ITEM 1.  BUSINESS

    To aid the reader, a "Glossary of Telecommunications Industry Terms," which
defines certain terms used in this "Business" section and elsewhere in this
Report, follows commencing on page 58.

INTRODUCTION

    The predecessor to Global TeleSystems Group, Inc. (the "Company" or "GTS")
was founded in 1983 as a not-for-profit company under the name San
Francisco/Moscow Teleport, Inc. The Company was incorporated as a California
for-profit corporation on September 25, 1986, and by way of a reincorporation
merger, merged with and into SFMT, Inc., a Delaware corporation formed for that
purpose on September 13, 1993. The Company was renamed Global TeleSystems
Group, Inc., on February 22, 1995. The Company's principal business office is
located at 1751 Pinnacle Drive, North Tower-12th Floor, McLean, Virginia 22102,
United States, and its telephone number is (703) 918-4500.

    The Company is a provider of a broad range of telecommunications services
to businesses, other telecommunications service providers and consumers in
Russia, the Commonwealth of Independent States ("CIS") and Central Europe.
Through its subsidiary Hermes Europe Railtel B.V. ("HER"), GTS is developing,
and operating the initial segments of, a pan-European high capacity fiber optic
network that is designed to interconnect a majority of the largest Western and
Central European cities and to transport international voice, data and
multimedia/image traffic for other carriers throughout Western and Central
Europe. GTS's strategy to develop its businesses generally has been to
establish joint ventures with a strong local partner or partners while
maintaining a significant degree of operational control. The Company's business
activities consist of the ownership and operation of (i) international long
distance businesses, which operate through international gateways that provide
international switching services and transmission capacity, (ii) local access
networks, which provide local telephone service, (iii) cellular networks, which
provide wireless telecommunications services, (iv) a domestic long distance
business, (v) data networks and (vi) carriers' carrier networks, which provide
high volume transmission capacity to other carriers.

    In Russia and the CIS, GTS's objective is to become the premier alternative
telecommunications operator. To attain its objective, the Company has partnered
with regional telephone companies and with Rostelecom, the national long
distance carrier in Russia. The Company currently operates in 24 oblasts
(regions) and the city of Moscow in Russia, as well as in 11 additional cities
in the CIS, and believes it is well-positioned to become the leading
independent telecommunications service provider in Russia. These businesses
include: (i) EDN Sovintel ("Sovintel"), which provides Moscow, and recently St.
Petersburg, with international long distance and local telephone services and
access to the major domestic long distance carriers; (ii) TeleCommunications of
Moscow ("TCM"), which provides local access services in Moscow; (iii) TeleRoss
(as defined below), which provides domestic long distance services in fourteen
cities in Russia, including Moscow, as well as Very Small Aperture Terminal
("VSAT") service to customers outside its primary long distance satellite
network; (iv) Sovam Teleport ("Sovam"), which provides data services, including
high-speed data transmission, electronic mail, Internet access services, as
well as Russia On Line, the first Russian language Internet service; and (v)
the Company's cellular operations ("GTS Cellular"), which operates cellular
networks in thirteen regions in Russia and also in Kiev, Ukraine, with licenses
covering regions with an aggregate population of approximately 25 million
people at the end of 1997. Whenever practical, GTS's businesses integrate and
co-market their service offerings in Russia and the CIS, utilizing TeleRoss as
the domestic long distance provider, Sovintel as the international gateway, TCM
and GTS Cellular for local access, and Sovam as the data communications and
Internet access network for business applications and on-line services.
Together, GTS's Russian and CIS ventures carried 442 million minutes of traffic
for the year ended December 31, 1997 and had approximately 33,300 customers,
including approximately 23,400 cellular subscribers, as of December 31, 1997.
See "-- Russia and the CIS."

    In Western Europe, GTS seeks to position itself as the leading independent
carriers' carrier through the development of two ventures, HER and GTS-Monaco
Access S.A.M. ("GTS-Monaco Access"). HER's objective is to become the leading
pan-European carriers' carrier by providing centrally managed cross-border



                                       5

 telecommunications transmission capacity to telecommunications companies
including traditional public telecommunications operators ("PTOs") and new
entrants, such as alternative carriers, global consortia of telecommunications
operators, international carriers, Internet backbone networks, resellers,
value-added networks and other service providers ("New Entrants") on an
approximately 18,000 kilometer pan-European high capacity fiber optic network
designed to interconnect a majority of the largest Western and Central European
cities. As of April 1, 1998, HER's network will link Brussels, Antwerp,
Rotterdam, Amsterdam, London, Paris, and Frankfurt. HER expects the initial five
country network and Switzerland to be placed in operation in the second quarter
of 1998. This segment of the network is expected to deliver managed transport
services over approximately 3,800 kilometers of fiber optic cable linking, in
addition to the cities discussed above, the cities of Zurich, Geneva,
Dusseldorf, Stuttgart, and Munich. The full 18,000 kilometer network is expected
to become fully operational during the year 2000. HER also plans to lease
capacity on a transatlantic cable linking the European network to North America
and is exploring various interconnectivity options to Russia and Asia. Such
intercontinental interconnectivity will help HER to satisfy the needs of its
European customers with respect to outgoing traffic and to attract additional
non-European customers with traffic terminating in Europe. HER commenced
commercial service over the Brussels-Amsterdam portion of the network in late
1996, and the London-Paris portion in November 1997. GTS-Monaco Access operates
an international gateway in Monaco in partnership with, and utilizing the
existing gateway infrastructure of, the Principality of Monaco and provides
transit and routing of international calls to other telecommunications
operators. Through its HER and GTS-Monaco Access ventures, GTS is building a new
network for transporting voice, data and multimedia/image traffic for other
carriers throughout Western and Central Europe and for worldwide international
voice, data and multimedia/image traffic that either originates or terminates
in, or transits through, Western and Central Europe. See " -- Western Europe."

    In Central Europe, GTS's objective is to become one of the leading
alternative telecommunications providers in the region. GTS currently provides
private data communications services to government and commercial customers in
Hungary and the Czech Republic. In the Czech Republic, the Company provides
outgoing voice services and operates an international gateway and a data
services network. In Hungary, GTS operates a VSAT network, which GTS believes
is the largest VSAT network in Central Europe as measured by number of VSAT
sites. The Company has also signed an agreement to provide international data
services in Poland, subject to the receipt of necessary governmental approvals.
GTS's strategy is to expand its service offerings as the regulatory environment
permits, leverage its existing VSAT and international gateway infrastructure
where possible and provide a broad range of services to its target markets. See
" -- Central Europe."

    Although GTS does not currently own or operate significant
telecommunication assets in Asia, GTS's objective is to become an established
and diversified telecommunications provider in China and India. GTS seeks to
leverage its position in these countries to capitalize on opportunities as they
arise. See "-- Asia."

    The following table sets forth certain information, as of December 31,
1997, for the principal ventures through which the Company conducts its
business:

BUSINESS STRATEGY

    GTS seeks to develop businesses to meet the rapidly expanding market demand
for telecommunications services. GTS's goal in emerging markets is to establish
itself as the leading alternative to the incumbent telecommunications service
providers and as a premier provider of value-added services. In addition, the
Company seeks to position itself as the leading independent carriers' carrier
within Western and Central Europe through the development of a pan-European
fiber optic network and an international gateway in Monaco.

    GTS believes that it will be able to successfully operate its businesses
and develop business opportunities by pursuing the following strategies:

    o   Identify and Seize Early Market Opportunities. GTS's primary strategy
        is to identify less developed markets in which the incumbent operator
        offers inadequate service and where liberalization of
        telecommunications regulations may be pending. The Company believes
        entering these less developed markets quickly is a key competitive
        advantage in the global telecommunications market. GTS leverages its
        management's knowledge of the markets in which the Company operates to
        assess and react quickly when attractive business opportunities arise.

    o   Establish Joint Ventures with Experienced Local Partners. GTS seeks to
        establish and maintain strategic partnerships and relationships with
        key telecommunications operators and service providers in the countries
        in which it operates. The Company believes that these relationships
        increase its ability to anticipate and respond to changes in the
        regulatory and legal environment and assist with license renewal and
        expansion of its operating companies.

    o   Retain Significant Operational Control. In general, GTS actively
        participates in the management of its ventures by (i) providing most of
        the funding for the ventures' operations, (ii) selecting key members of
        the local management team, (iii) developing business plans and
        marketing strategies together with local management, (iv) monitoring
        operating functions, (v) maintaining close working relationships with
        local partners and (vi) integrating its networks and businesses in a
        manner which is consistent with the Company's overall strategic
        objectives.

    o   Build Infrastructure to Provide High Quality Services. GTS continues to
        develop and expand its network infrastructure. The Company believes
        that its networks offer service, quality and cost advantages over
        incumbent providers as a result of the Company's customer support,
        network monitoring, management systems and its ability to integrate and
        co-market its service offerings.

    o   Leverage Management Depth and Experience. GTS's management has
        significant experience in the development and operation of
        telecommunications businesses outside the United States. The Company
        believes that this experience, together with the Company's extensive
        operations, has provided its management with the ability to identify,
        evaluate and pursue international telecommunications business
        opportunities. Additionally, GTS has assembled a management team
        comprised of executives with extensive experience managing
        telecommunications companies in the respective local markets. GTS
        believes that its management team possesses a broad knowledge of
        relevant political and regulatory structures, as well as the


                                       8
<PAGE>   9

        cultural awareness and fluency with international and local business
        practices necessary to implement the Company's objectives.

    o   Ability to Access Capital. In general, the Company's financing strategy
        is to establish parent level funding to meet general corporate needs
        and the costs of start-ups and acquisitions and, when it is possible
        and cost-effective, to finance ongoing operations at the venture level.
        From 1993 through 1997, the Company raised privately approximately $268
        million in equity and approximately $215 million of debt (of which
        approximately $74 million was raised through shareholders). In
        addition, HER completed a $265 million private placement of senior
        notes (of which $56.6 million was placed in escrow for the first two
        years' interest payments) in 1997. On February 10, 1998, the Company
        completed an initial public offering of its common stock. The Company
        sold 12,765,000 shares in the offering, including 1,665,000 shares sold
        as a result of the exercise of over-allotment options granted to the
        underwriters of the offering and realized net proceeds of $238.7
        million from the offering after the payment of underwriting fees but,
        before payment of other expenses associated with the offering. On the
        same date, the Company also sold $105 million aggregate principal
        amount of 9-7/8% Senior Notes due 2005 ("the Senior Notes"), and
        realized net proceeds of $82.3 million, after the payment of
        underwriting fees and the deposit of $19.6 million in escrow to cover
        the first four scheduled payments of interest on the Senior Notes, but
        before expenses associated with the sale of the Senior Notes.

    In addition to its overall business strategy, GTS has developed specific
market strategies to achieve its goals in emerging markets and Western Europe.

    Emerging Markets. The Company pursues its goals in emerging markets through
a three-stage approach of market entry, market expansion and market
integration.

    o   Market Entry. GTS identifies a market as a suitable target for entry
        based upon: (i) superior growth prospects for such market, demonstrated
        by growing demand for high quality telecommunications services; (ii)
        the provision of inadequate services by incumbent providers, typically
        resulting from the incumbents' unwillingness to offer high quality
        services with reliable customer support at attractive prices; and (iii)
        attractive regulatory environments in which emerging alternative
        telecommunications providers such as GTS have, or expect to have over a
        clearly defined time horizon, the ability to compete on a substantially
        equal basis with the incumbent providers in terms of certain services
        and the cost of providing those services. Once GTS has identified a
        market as suitable for entry, the Company seeks to establish its
        presence in that market by establishing a venture with a strong local
        partner or partners. In general, GTS maintains a significant degree of
        operational control in such ventures. Through such ventures, the
        Company benefits from its partners' ability to provide infrastructure,
        regulatory expertise and personnel that will provide GTS with a
        competitive advantage in entering that market. When entering a new
        market, GTS's strategy is to provide its customers with higher quality
        service as compared to the services offered by incumbent providers.

    o   Market Expansion. Having entered a market successfully and established
        a limited service offering to its targeted customer base, GTS then
        seeks to expand the range of services it offers to existing and
        potential customers and to further develop its relationships with local
        partners. By broadening its service offerings, GTS anticipates
        achieving increased economies of scale through the common use of
        administrative and operating functions already in place, increasing the
        Company's share of its customers' telecommunications spending and
        expanding GTS's base of potential customers through the provision of a
        bundled service offering. The Company also seeks to expand its targeted
        geographic market by forming new partnerships, installing
        infrastructure and offering services in additional geographic regions,
        allowing the Company to further enhance its operating leverage and
        ability to service its customers' telecommunications needs.

    o   Market Integration. GTS ultimately intends to integrate and co-market
        its service offerings in each of the markets in which it operates. The
        Company believes such integration enables it to enhance its operating
        efficiency by leveraging its distribution channels, infrastructure and
        networks, and management information systems. As customers develop a
        need for a broader variety of telecommunications services, the Company


                                       9
<PAGE>   10

        believes GTS's integrated operations will represent an attractive
        service alternative for customers seeking a single provider with the
        ability to meet all their telecommunications needs.

    Western Europe. The Company seeks to position itself as the leading
independent carriers' carrier within Western Europe through the development of
HER's pan-European fiber optic network and the operation of GTS-Monaco Access's
international gateway in partnership with, and utilizing the gateway
infrastructure of, the Principality of Monaco. The overall strategy of GTS in
Western Europe is to complement and enhance the services provided by PTOs and
New Entrants in a way that helps them to more successfully meet the needs of
their end-user customers. HER seeks to enter the market ahead of competition
and encourage a wide variety of carriers to use its network with service
offerings that meet their needs. To establish itself as the leading carriers'
carrier for international telecommunications within Europe, HER intends to
provide its customers with significantly higher quality transmission and
advanced network capabilities at a competitive price by utilizing advanced,
uniform technology across the region and providing redundant routing for higher
levels of reliability.

RUSSIA AND THE CIS

OVERVIEW

    GTS is a leading provider of a broad range of telecommunications services
in Russia. GTS's services include international long distance services,
domestic long distance services, high speed data transmission and Internet
access, cellular services and local access services. GTS was among the first
foreign telecommunications operators in the CIS, where it began offering data
links to the United States in 1986, international long distance services in
1992, local access to its networks in 1994 and cellular services in 1995. GTS
has developed these businesses into a leading provider of telecommunications
service offerings in Russia by building its own infrastructure, including a
fully digital overlay network and interconnections with its local Russian
telecommunications partners.

    The Company believes that evolving changes in government policy over the
last several years and the overall inadequacy of basic telecommunications
services throughout Russia have created a significant opportunity. Before 1990,
all international, domestic long distance and local telecommunications in the
Soviet Union were provided by a monopoly state telecommunications company
managed by the Ministry of Posts and Communications. In 1990, the Council of
Ministers established a joint-stock company called Sovtelecom and transferred
to it all of the telecommunications assets and operations of the Soviet
Ministry of Posts and Communications. Following the dissolution of the Soviet
Union in 1991, the name of the company was changed to Intertelecom. In 1992,
the Russian government decided to split Intertelecom into several components to
foster privatization, competition and investment. The international and
long-distance assets and operations were combined into Rostelecom, creating a
monopolistic service provider. The local telecommunications assets and
operations were broken up into 88 independent regional joint-stock companies,
seven of which serve cities, including the Moscow City Telephone Network and
the Petersburg Telephone Network. Most of the regional companies have a
telecommunications trunk operator and provide a domestic long distance service
within their service region. Domestic long distance calls to and from areas
outside the companies' service area, as well as international calls, are
switched to and from Rostelecom, which forwards the calls to and from another
regional company or a foreign carrier for international calls. Exceptions to
this rule include the seven city operators. In Moscow and St. Petersburg, the
trunk operators have been isolated into separate, long distance companies
called Moscow MMT and St. Petersburg MMT. All domestic long distance and
international calls originating from or terminating in Moscow and St.
Petersburg are switched through the MMTs, which forward the calls to and from
Rostelecom.

    Following the former Soviet Union's transformation from a centralized
economy to a more market-oriented economy, increased demand from emerging
private businesses and from individuals, together with the poor state of the
public telephone network, has led to rapid growth in the telecommunications
sector in Russia and the CIS. In 1991 the Ministry of Communications (the
"MOC") was established as the Russian successor to the Soviet Ministry of Posts
and Communications to regulate and improve the telecommunications industry and
to be the government's representative for its ownership share of the 88
regional operating companies, the assets currently held by (then the monopoly
international and domestic long distance service provider) and national radio,
television and satellite 


                                      10
<PAGE>   11


operating companies. This enabled the MOC and operating organizations to begin
the privatization process, attract foreign investment and initiate joint
ventures with foreign partners.

    Although it remains subject to certain restrictions, significant progress
in privatization of the telecommunications industry in Russia and the CIS has
occurred. Under Russian law, state-owned enterprises within the
telecommunications sector were subject to privatization but only pursuant to a
decision of the Russian government in each individual case and with the state
retaining a certain percentage of the stock of the privatized entity for three
years, subject to extension for national security reasons. At present,
virtually all of the former state telecommunications enterprises have been
privatized and, subject to the above restrictions, shares of the newly formed
joint stock companies have been sold to the public. Also, a significant number
of private operators provide a wide variety of telecommunications services
pursuant to licenses from the MOC to a growing number of customers throughout
Russia. According to the MOC, more than 6,000 licenses have been granted to
telecommunications operators in Russia, a large portion of which is assumed to
represent licenses reissued to the same operators as a result of their
reorganization or obligation to hold such licenses on counterfeit-proof paper.

    In October 1994, the President authorized the establishment of Svyazinvest
with the stated purpose of fostering greater efficiency and economies of scale
within the industry through competition. As a wholly government-owned company,
Svyazinvest was granted a controlling stake in approximately 85 regional
telecommunications companies in order to compete in these respective markets.
Svyazinvest was also given control of more than 20 million of the 25.5 million
telephone lines in Russia, except in Moscow and St. Petersburg.

    In April 1997, President Yeltsin approved the transfer of the federal
government's 51% stake in Rostelecom, as well as similar stakes in Central
Telegraph (the national PTO), the Ekaterinburg City Telephone Network and
Giprosvyaz (a telecommunications research institute), to Svyazinvest. On July
30, 1997, Mustcom Ltd., a Cyprus-based company that represents the interests of
a consortium which includes ICFI Cyprus, Renaissance International Ltd.,
Deutsche Morgan Grenfell, Morgan Stanley, and an affiliate of George Soros,
purchased a 25% stake in Svyazinvest for $1.87 billion. The President has also
authorized the sale of another 24% of Svyazinvest at a future date. This sale
is scheduled to occur in the second half of 1998 and is currently reserved
solely for Russian investors. The Russian government has announced that it will
retain a controlling 51% interest in Svyazinvest.

    As a result of the government's actions, a single entity, Svyazinvest, now
owns a majority interest in most of the Company's principal venture partners
and other telecommunication service providers in Russia which together provide
a range of international and domestic long distance and local
telecommunications services throughout Russia. The consolidation of many of its
partners under Svyazinvest and the possible sale of a significant interest in
Svyazinvest to foreign and/or Russian investors will likely subject the Company
to more coordinated competition from Svyazinvest, and may lead to material
adverse changes in the business relationships between the Company and such
partners, which business relationships represent a material component of the
Company's business strategy in Russia. There can be no assurance that the
continuing privatization of Svyazinvest, or the evolution of government policy
regarding Svyazinvest and Rostelecom, will not have a material adverse effect
on the Company or its ventures.

    The Russian government's interest in Svyazinvest is held by the MOC, which
was reclassified as the State Committee on Telecommunications and Informatics
during a recent government reorganization. The MOC remains the central body of
federal authority in the Russian Federation, having responsibility for state
management of the communications industry and supervisory responsibility for
the condition and development of all types of communications.

    Despite the recent changes in the Russian telecommunications industry, the
level of telecommunications service generally available from most public
operators in Moscow remains significantly below that available in cities of
Western Europe and the United States, although in recent years, the Moscow
local telephone infrastructure has benefited from significant capital
investment. By 1995, there were approximately 16 lines per 100 persons in
Russia and 45 lines per 100 persons in Moscow. In comparison, there were 60 and
58 lines per 100 persons in the United States and Western Europe, respectively.
In addition, the quality of services, reflected as the percentage of digital


                                      11
<PAGE>   12

switching in local telephone networks, currently is approximately 12% in Russia
compared to 65% and 66% in the United States and Western Europe, respectively.

    Outside Moscow (and to a lesser extent St. Petersburg), most standard
Russian telecommunications equipment is obsolete. For example, many of the
telephone exchanges are electromechanical and most telephones still use pulse
dialing. The Russian population is over 145 million, of which approximately
two-thirds is concentrated in urban areas. The telecommunications market in
Russia currently includes a number of operators that compete in different
service offering segments -- local, inter-city, international, data and
cellular services. In large measure, the relative lack of economic development
in the regions accounts for the lack of improvement in local telecommunications
infrastructure. Although the regions still generally rely on an outdated
infrastructure inherited from the former Soviet Union, they are starting to
resort to sophisticated sources of finance, such as municipal bond offerings,
in order to upgrade it.

    Growth in the Russian telecommunications industry has been principally
driven by businesses in Moscow requiring international and domestic long
distance voice and data services and by consumers using mobile telephony. This
growth has been most significant as multinational corporations have established
a presence in Moscow and Russian businesses have begun to expand. The service
sector, which includes operations in distribution, financial services and
professional services and tends to be the most telecommunications-intensive
service sector of the economy, is growing rapidly in Moscow. Since moving to a
more market-oriented economy, the economic conditions in the outlying regions
in Russia have also generally improved. The telecommunications industry in the
outlying regions has experienced recent growth, principally as a result of
growth in the industrial sector as well as the establishment of satellite
offices in the regions by multinational corporations and growing Russian
businesses. The extent of overall market growth will depend in part on the rate
at which the Russian economy expands, although recent revenue growth in the
sector has been significant (in spite of a declining economy in certain
regions) because of increasing traffic from pre-existing customers and the
normalization of tariffs for business services.

    The Company believes it is well-positioned to take advantage of market
growth factors due to (i) its early market entry, (ii) its strong
infrastructure position in Moscow, by far the most important regional market,
(iii) the local market experience of its local partners, (iv) the extent of its
existing customer base and (v) its extensive range of international and
domestic telecommunications services. GTS believes it is the only operator in
Russia currently capable of providing a broad range of service offerings and
marketing them as a single end-to-end service offering for its customers.

STRATEGY

    GTS's objective is to become the premier alternative carrier in Russia and
other key growth markets of the CIS. To attain this objective, the Company has
developed and implemented the following strategy:

    o   Develop Strong Local Partnerships. The Company has and continues to
        develop its Russian and CIS business through alliances with experienced
        local partners, which to date have been primarily regional telephone
        companies and Rostelecom. These ventures combine the management,
        financial and marketing expertise of GTS together with its partner's
        ability to provide infrastructure and local regulatory experience. GTS
        believes that these relationships lend it credibility and increase its
        ability to anticipate and respond to the evolving regulatory and legal
        environment. GTS maintains a significant degree of managerial and
        operational control in its joint ventures through its foundation
        documents, which enable GTS to develop them in a manner consistent with
        its overall strategic objectives.

    o   Expand Customer Base. The Company continues to expand its customer base
        through the provision of basic telephone and digital services in
        markets where such services are not currently provided. Once they have
        established a presence in a market, the Company's ventures seek for
        opportunities to expand further into neighboring regions and cities.



                                      12
<PAGE>   13

    o   Increase Range of Digital Services. As its business customers expand
        their operations throughout Russia and the CIS and as their
        telecommunications needs become more sophisticated, the Company seeks
        to increase its revenues by expanding the range of integrated digital
        services offered to its customers.

    o   Offer High Quality Telecommunications Service and Customer Service. The
        Company continues to invest in and build sophisticated high-speed
        digital networks and other infrastructure through which customers can
        gain local access to the Company's services. In addition to providing
        advanced, high quality network infrastructure, the Company emphasizes
        and offers its customers a level of customer service which the Company
        believes cannot be found elsewhere in the market.

    To date, GTS has made substantial progress employing this strategy. The
Company provides digital voice, data and local services in Moscow through its
Sovintel, Sovam and TCM ventures and provides these same services to thirteen
additional Russian cities through its TeleRoss long distance network.

OPERATIONS

    GTS provides a broad range of telecommunications services in Russia,
including international long distance services, domestic long distance
services, cellular services, high speed data transmission, Internet access and
local access services. These services are supported by operator assistance,
itemized call reporting and billing, and other value-added capabilities that
leverage GTS's investment in advanced switching, data collection and processing
equipment. GTS also provides customized systems integration, including PABXs,
key systems, wiring and interconnectivity. GTS's own infrastructure is
supplemented with dedicated and leased capacity to allow GTS to bypass the
severely congested and poorly maintained local, domestic and long distance
circuits of the Russian carriers.

    Whenever practical, GTS's business units integrate and co-market their
service offerings, utilizing TeleRoss as the long distance provider, Sovintel
as the international gateway, TCM and GTS Cellular for local access, and Sovam
as the data communications and Internet access network for business
applications and on-line services. Through this integrated marketing approach,
GTS is able to provide comprehensive telecommunications solutions to
multinational corporations operating throughout Russia and the CIS. Several of
the TeleRoss Ventures and the cellular joint ventures were not operational, or
had just commenced operating, in 1995. As a result, TeleRoss and GTS Cellular
did not generate significant revenues in 1995.

Company's operating ventures in Russia and the CIS.

SOVINTEL

    GTS owns 50% of Sovintel, a joint venture with Rostelecom, the national
long distance carrier. Sovintel was founded in 1990 by GTS, Rostelecom and GTE
Spacenet, with GTS acquiring GTE Spacenet's interest in 1994. Sovintel markets
a broad range of high quality telecommunications services by (i) directly
providing international direct dial access to over 170 countries and private
line dedicated voice channels and (ii) leveraging the 


                                      13
<PAGE>   14


infrastructure and services of the other GTS ventures, including TeleRoss, TCM
and Sovam. In addition, Sovintel provides and installs for its customers
equipment such as PABXs, key systems and wiring and provides maintenance and
other value-added services. Sovintel customers, which primarily consist of
businesses, hotels and Moscow-based cellular operators, are able to access
these telecommunications services through Sovintel's fully-digital overlay
network in Moscow. In addition, Sovintel has recently commenced construction of
a limited network in St. Petersburg that is interconnected to Sovintel's Moscow
network and is intended to support Sovintel's Moscow clients which have a
presence in St. Petersburg. Sovintel serviced over 43,900 telephone numbers, or
"ports," for business customers and cellular providers and had over 275
employees as of December 31, 1997.

    Sovintel has constructed and operates a fully-digital overlay network in
and around Moscow which consists of (i) an approximately 600-kilometer fiber
optic ring, (ii) over 250 PABXs linked to the fiber optic ring, (iii) a
fully-digital microwave network, (iv) a wireless local loop and (v) an
international gateway connected to the fiber optic ring. In addition, Sovintel
leases dedicated international long distance channels. Customers are connected
to the Sovintel network via last mile connections to over 250 PABXs that
provide "points-of-presence" in and around Moscow. The PABXs are connected to
the network through a direct fiber connection or a digital microwave network.
Some of Sovintel's new customers are temporarily connected to the network
through a wireless local loop. The wireless local loop provides a significant
competitive advantage because it allows Sovintel to connect customers to its
network more quickly than alternative methods. As these customers are provided
permanent connections to Sovintel's network through direct connections to the
PABXs, additional customers are rolled onto the wireless local loop.

    After a customer is connected to the Sovintel network, local telephone
services are provided through the Sovintel fiber optic ring's interconnection
with the switches of either TCM or MTU Inform. These switches provide access to
local telephone service in Moscow through interconnections with the Moscow city
telephone network ("MGTS") and the principal Moscow cellular providers.
Sovintel provides its customers access to domestic long distance service
through the TeleRoss long distance network, or through Rostelecom's network in
cities not currently served by TeleRoss. International service is provided
primarily through the Sovintel international gateway, which transmits
international traffic via dedicated international leased long distance
channels. Sovintel's customers also can receive high speed data services
through Sovintel's interconnection with the Sovam data network. Accordingly,
from a customer's perspective, Sovintel offers a broad range of
telecommunication services.

    The following table sets forth certain operating data related to Sovintel's
operations:

    Services. Sovintel markets a broad range of high quality telecommunications
services by (i) directly providing international direct dial access to over 170
countries and private line dedicated voice services and (ii) by leveraging the
infrastructure and services of the other GTS ventures. Sovintel's services
include:

    o   Switched International, Domestic Long Distance and Local Services.
        Customers are provided switched international long distance services
        directly through Sovintel's international gateway in Moscow and its
        leased long distance channels. Domestic long distance services are
        marketed by Sovintel and provided either through the TeleRoss long
        distance network or, where the call destination is not served by
        TeleRoss, through Rostelecom's network. Local call service is provided
        by Sovintel indirectly as a result of its interconnection, through TCM
        or MTU Inform, with the Moscow city telephone network. Based on its
        familiarity with the market, the Company believes that Sovintel's
        services are distinguished by a higher level of quality than those of
        its competitors, particularly with respect to call completion rates for
        its domestic long distance and local call services. In addition, the
        Company trains its employees to provide customer service at a level
        which is comparable to that provided by Western telecommunications
        companies. As a result, the Company believes that customers choose
        Sovintel over its competitors because it has earned a reputation for
        providing high quality telecommunications services through an
        experienced and professional customer service staff.

    o   Private Line Channels. Private line channels, which are provided over
        dedicated leased lines, are principally utilized by customers with
        high-volume data traffic needs, such as Sovam and large data providers.
        Private line customers have access to intra-city service in Moscow
        through Sovintel's fiber optic ring and to inter-city service between
        Moscow and St. Petersburg via fiber leased by Sovintel, in each case
        benefiting from Sovintel's high quality infrastructure. Private line
        domestic long distance service is provided through TeleRoss and, for
        cities not served by TeleRoss, through Rostelecom. International
        private line service is provided through dedicated leased fiber
        channels from Rostelecom.

    o   Equipment Sales, Installation Services and Project Planning and
        Management Services. In providing the above services to its customers,
        Sovintel installs and maintains equipment on its customers' premises,
        including PABXs, key systems and wiring. Sovintel also provides project
        planning and management services, including system design and
        management, to its customers.

    o   World Access Service. Customers are able to access Sovintel's
        international long distance services through the World Access Card,
        which provides customers either direct or calling-card-based portable
        access to domestic and international long distance service. The calling
        card can be used in 15 Russian cities, including Moscow and St.
        Petersburg, and 23 countries.

    Sovintel complements its service offerings by providing a wide range of
value-added services including operator assistance, maintenance and customer
support and itemized call reporting and billing.

    Customers and Pricing. Sovintel's customers consist primarily of
high-volume business and professional customers, such as IBM, Credit Suisse
Group and Reuters, other multinational corporations and Russian enterprises, a
number of premium Moscow hotels and other telecommunications carriers. In
addition, Sovintel is one of the primary providers of domestic and
international long distance service for the major cellular service providers in
Moscow, including VimpelCom, MTS and Moscow Cellular. Sovintel's customers
typically demand a higher level of service than generally available in the
market. Sovintel further provides to its large corporate customers data
services such as frame relay and Internet access contracted from Sovam in order
to offer "one-stop shopping" telecommunications solution to these customers,
who increasingly require this type of service.

    The pricing structure for international and domestic long distance calls is
based upon traffic volume and overall market rates, with Sovintel's rates
varying depending on the time and destination of the call. Local calls, other
than calls placed to cellular phones, are completed without charge. Sovintel
expects to continue its practice of not charging to complete local calls unless
and until the MGTS begins to charge for completion of such calls. Sovintel





                                      15
<PAGE>   16

prices its international long distance services slightly below those of its
principal competitors, and has recently reduced its rates in anticipation of
increased competitive pricing pressures. Sovintel's average revenue per minute
for outgoing international long distance calls has declined from approximately
$2.35 per minute for the year ended December 31, 1994 to approximately $1.12
per minute for the year ended December 31, 1997. Sovintel expects increased
pricing pressure from competitors over time. Sovintel prices domestic long
distance services in line with those of its principal competitors, however, due
to its obligations under certain agreements with affiliated entities,
Sovintel's margins for these services are declining. Prices for domestic long
distance services have increased significantly over the last several years,
although such prices stabilized in the second half of 1996. Sovintel's private
line services are priced competitively. Sovintel provides private line channels
by releasing lines it leases from Rostelecom. The lines are leased by Sovintel
from Rostelecom at wholesale rates and leased by Sovintel to its customers at
prices in line with Rostelecom's retail rate.

    Customers are billed monthly with larger-volume customers receiving
discounts of up to 25%. Customers using international services, domestic long
distance or data services are billed in U.S. dollars. To the extent permitted
by law, payment is made either in U.S. dollars or in rubles at the ruble/dollar
exchange rate at the time of payment, plus a conversion charge in order to
minimize the impact of currency fluctuations. Sovintel currently bills on an
invoicing system that was internally developed. Currently, the system is
adequate for Sovintel's present customer base; however, the Company is
evaluating alternatives for upgrading the system in anticipation of future
growth.

    Sales and Marketing. Sovintel's sales and marketing strategy targets large
multinational and Russian businesses both directly and through contacts with
real estate developers and business center managers in the greater Moscow area.
These developers and managers typically determine which telecommunications
service provider will service their respective properties. By identifying and
building relationships with these developers and managers at an early stage
(typically up to one year prior to the completion of a new building project),
Sovintel seeks to enhance the likelihood of winning the service contract. In
addition to its traditional target market, Sovintel has recently begun to
market its services to smaller businesses. Sovintel utilizes a departmentalized
sales force in order to focus its sale efforts on the different segments within
its target market. The sales force is comprised of 40 sales personnel,
including 15 account managers, all of whom specialize in serving specific
targeted industries. Dedicated marketing and customer support personnel provide
technical support, customer service, training, market monitoring and
promotional functions for Sovintel. Sovintel's sales and marketing personnel
are paid through a combination of salary, commissions and incentive bonuses.

    Ownership and Control. Sovintel is a joint venture between a wholly owned
entity of GTS and Rostelecom with each having a 50% ownership interest. Under
Sovintel's charter, GTS and Rostelecom each have the right to appoint three of
the six members of Sovintel's managing board. Rostelecom has the right to
nominate the Director General (the highest ranking executive officer at
Sovintel), while GTS has the right to nominate the First Deputy Director
General (the next-highest ranking executive officer at Sovintel). In practice,
the Director General and the First Deputy Director General together perform the
role of a chief executive officer. Certain business decisions, including the
adoption of Sovintel's annual budget and business plan as well as the
distribution of profits and losses require the approval of both GTS and
Rostelecom. Neither GTS nor Rostelecom are obligated to fund Sovintel's
operations or capital expenditures. Losses and profits of Sovintel are
allocated to the partners in accordance with their ownership percentages, in
consideration of funds at risk. As of December 31, 1997, GTS and Rostelecom
have each made equity contributions of $1.0 million to Sovintel. The Sovintel
joint venture agreement does not have an expiration date. See "--Certain
Considerations Generally Applicable to the Company's Operations-- Dependence on
Certain Local Parties; Absence of Control" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations --- Accounting
Methodology --- Profit and Loss Accounting."

TCM

    GTS beneficially owns approximately 50% of TCM, a joint venture founded in
1994 that provides a licensed numbering plan and interconnection to the Moscow
city telephone network for carriers needing basic local access service in
Moscow. GTS's partners in TCM are MTU-Inform and a group of entrepreneurs with
extensive telecommunications experience. TCM is currently licensed to provide
100,000 numbers in Moscow, of which approximately 50,000 have been leased. TCM
has contracted with MGTS to construct up to an additional 100,000

                                      16

<PAGE>   17

numbers in several stages over the next five years, and currently plans to
construct 10,000 numbers in each of 2000, 2001 and 2002. Any such construction,
however, is subject to TCM obtaining a license covering the additional numbers
and the availability of such numbers in the portion of the MGTS numbering plan
in which TCM plans to construct such numbers. TCM's switching facilities are
fully integrated with the networks of Rostelecom, Sovintel, and MGTS, allowing
it to provide high quality digital service to its customers.

    Services. TCM acts as a local gateway by providing numbers and ports to
carriers in Moscow, including Sovintel, VimpelCom, MTS and Moscow Cellular, and
thus providing interconnectivity to the Moscow city telephone network. Access
to the Moscow city telephone network provides customers with the higher quality
and broader range of services available in Moscow, such as the services
provided by Sovintel. Access from outlying regions is typically obtained
through a domestic long distance service provider such as TeleRoss. See "--
Sovintel" and "-- TeleRoss."

    Customers and Pricing. TCM provides its services on the wholesale level to
primary carriers. VimpelCom is TCM's primary customer and accounts for
substantially all of TCM's revenues, hence the loss of VimpelCom as a customer
would have a material adverse effect on the Company. TCM also provides ports to
Sovintel and to other network operators. TCM's ports are leased principally to
carriers in Moscow. Although local access services are priced upon the basis of
supply and demand factors in the local market, in general, for each port
cellular operators pay an approximately $300 installation fee and a $16 flat
monthly fee plus a per minute charge for traffic while other carriers pay a
larger initial fee of approximately $500 and a monthly fee of approximately
$25. Local access services are typically provided pursuant to five-year
contracts that may be renewed upon expiration for additional one-year periods.
TCM has entered into an agreement with Sovintel pursuant to which billing and
collecting functions for TCM-Sovintel joint customers are performed by
Sovintel, with Sovintel remitting such amounts (less applicable settlement
charges and administrative costs) to TCM. The rapid growth of cellular services
in markets like Moscow has placed a premium on new numbers, which has
translated into attractive prices for these numbers. TCM, however, believes
these prices will decline over time.

    Ownership and Control. GTS's indirect interest in TCM is represented by its
approximately 52% interest in a holding company, which owns 95% of TCM. This
structure provides GTS with 50% beneficial ownership interest in TCM. Decisions
of the holding company regarding TCM require unanimous board approval and
neither GTS nor its partner in the holding company is obligated to fund
operations or capital expenditures of the holding company. In addition, neither
the holding company nor the TCM shareholders are obligated to fund operations
or capital expenditures of TCM. At both the holding company and TCM level,
losses and profits are allocated to the partners in accordance with their
ownership percentages, in consideration of funds at risk. GTS acquired its
indirect, 50% beneficial interest in TCM for approximately $700,000 and certain
additional consideration. As of December 31, 1997, GTS had no outstanding loans
relating to TCM. None of the operative charters and agreements relating to the
holding company or TCM have expiration dates. See "Certain Considerations
Generally Applicable to the Company's Operations -- Dependence on Certain Local
Parties; Absence of Control" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations --- Accounting Methodology ---
Profit and Loss Accounting."

TELEROSS

    TeleRoss, which began operations in 1995, consists of (i) two wholly owned
holding companies and a 99% owned subsidiary of GTS that operates a domestic
long distance network (collectively, the "TeleRoss Operating Company") and (ii)
thirteen joint ventures that are 50% beneficially-owned by GTS that originate
traffic and provide local termination of calls (the "TeleRoss Ventures" and,
together with TeleRoss Operating Company, "TeleRoss"). The TeleRoss domestic
long distance network serves fourteen major Russian cities, including Moscow
and, through VSAT technology, 24 customers located outside these cities.
TeleRoss provides digital domestic long distance services and other value-added
services through its own infrastructure as well as access to Sovintel's
international gateway services and access to the Moscow city telephone network
through TCM's switching facilities. Sovam uses the TeleRoss digital channels to
provide regional data service and has co-located its access facilities with
TeleRoss. As of December 31, 1997, TeleRoss employed approximately 188 persons
of which approximately


                                      17
<PAGE>   18

90 people were based in Moscow and approximately 98 people were deployed in the
regions in which TeleRoss operates.

    TeleRoss's licenses cover the city of Moscow and a total of 39 regions
throughout Russia. Most of the thirteen cities in which TeleRoss primarily
operates are regional capitals, with an aggregate population of approximately
12 million. TeleRoss's licenses cover the entire oblast surrounding these
cities, with populations totaling approximately 38 million persons, and GTS
intends eventually to extend the reach of the TeleRoss network beyond the
regional capitals to the surrounding areas. The cities in which TeleRoss
currently offers its services are: Arkhangelsk, Ekaterinburg, Irkutsk,
Khabarovsk, Krasnodar, Nizhni Novgorod, Novosibirsk, Syktyvkar, Tyumen, Ufa,
Vladivostok, Volgograd and Voronezh. The Company has formed an additional
TeleRoss Venture in the city of Samara. As of March 1998, this venture was not
operational.


    The TeleRoss network architecture involves local city switches connected to
remote earth stations which communicate via satellite to a Moscow-based hub.
This hub consists of the network control center, earth station equipment,
multiplexing equipment and a switch. The earth stations, hub and related
equipment are owned by TeleRoss, which gives TeleRoss the flexibility to
redeploy network assets to other locations as necessary. The hub interconnects
to Sovintel's network providing access to Sovam's data networks, TCM's
switching facilities and Sovintel's international gateway, which transports
international traffic via dedicated international leased satellites and fiber
channels and provides access to Rostelecom's long distance networks. Outside of
Moscow, TeleRoss's local joint venture partners provide interconnection to the
local public telephone networks in each of the cities it serves. In addition to
providing services through its network, TeleRoss currently serves 24 customers
in 24 additional cities through VSAT technology which links the customers via
satellite to the Moscow hub.

    The following table sets forth certain operating data related to TeleRoss's
operations:

    Services. Through its network and VSAT offerings, TeleRoss offers the 
following services:

    o   Carriers' Carrier Services. TeleRoss provides services as a "carriers'
        carrier," providing domestic long distance carrier services to cellular
        operators, Sovintel, the TeleRoss Ventures' regional partners and
        competitive bypass operators from the cities in which the TeleRoss
        Ventures operate, and to customers in 


                                      18
<PAGE>   19


        remote cities using VSAT stations. These services are provided to and
        from Moscow, and are provided by TeleRoss at wholesale rates
        competitive with those offered by Rostelecom. TeleRoss also provides
        private line channels to Sovam in cities where the TeleRoss Ventures
        operate. In addition, TeleRoss has recently received a license to
        provide international private line service.

    o   World Connect Dial/Russia Connect Dial. Customers in TeleRoss's cities
        are provided dedicated local access to the regional TeleRoss switch
        through lines leased from the TeleRoss Venture's regional joint venture
        partner. These customers then have access to the domestic long distance
        service provided by TeleRoss, international long distance service
        provided by Sovintel and are fully integrated into the local phone
        networks operated by the applicable TeleRoss Venture's partner and to
        the Moscow city telephone network through TCM.

    o   Moscow Connect. Customers are provided with dedicated last mile
        connection over lines leased from the regional joint venture partner
        which lines are connected to a local TeleRoss switch. The TeleRoss
        network and its interconnection to TCM provide customers with a Moscow
        dial tone which allows users in remote locations better access to
        Moscow's advanced telecommunications infrastructure. In addition,
        Moscow Connect service provides better call quality at lower rates for
        domestic and international long distance. Moscow Connect also
        facilitates communications between users and their Moscow-based
        associates as calls can be made to and from Moscow without the use of
        prefixes and without long distance charges accruing to the Moscow-based
        parties.

    o   Dedicated Circuits. Customers are provided with point-to-point clear
        channel circuits within Russia and internationally through the TeleRoss
        backbone and its interconnection with Sovintel's international gateway
        in Moscow. Dedicated circuits are generally used by news services,
        banks and other commercial customers who require high capacity and high
        quality service. This service can be used for voice or data, depending
        on the user's needs. In providing dedicated circuits, TeleRoss competes
        against other alternative communications providers, however, TeleRoss
        believes that it has a distinct price advantage over its competitors
        because of the use of its own infrastructure and the bulk purchase of
        satellite capacity.

    o   World Access Service. TeleRoss and Sovintel co-market World Access
        Service to their customers in each of the cities they serve through two
        products: World Access Direct and World Access Card. Through World
        Access Direct, TeleRoss customers can access domestic long distance and
        international service anywhere within the customer's city through the
        local telephone network. The World Access Card is a calling card which
        allows TeleRoss customers portable access to domestic long distance and
        international service from 15 Russian cities, including Moscow and St.
        Petersburg, and 23 countries. This service is provided through
        Sovintel's infrastructure.

    o   VSAT Services. For customers that are located outside the cities
        serviced by TeleRoss or that cannot be physically linked to TeleRoss's
        regional switches, TeleRoss offers VSAT service which connects these
        customers directly to TeleRoss's Moscow-based hub through a VSAT
        antenna installed at the customer's location. Both dedicated and
        switched services are provided through these VSAT arrangements.

    In addition to continuing the development of its core domestic long
distance business, TeleRoss's strategy includes the development of local access
networks to capitalize on demand for local phone service and to capture
additional customers for its long distance and value-added service offerings.
Outside Moscow, TeleRoss has primarily pursued a strategy whereby it develops
its own intra-city trunking network with copper based or fiber optic facilities
leased from the regional joint venture partners. As of December 31, 1997,
TeleRoss, in conjunction with regional joint venture partners, has installed
approximately 25 kilometers of fiber optic cable in 3 cities and plans to
install an aggregate of approximately 100 kilometers of additional fiber optic
cable in up to an additional 6 cities over the next 24 to 30 months. Customers
who obtain local phone numbers from TeleRoss's venture partners are directly
interconnected to the local telephone company and to the Company's long
distance network and Sovintel's international gateway and may obtain a broad
range of value-added services offered by the Company.

    Customers and Pricing. TeleRoss's customers include businesses and other
telecommunications service providers such as carriers, PTOs, cellular
operators, Sovintel and Sovam. TeleRoss's business customers consist of large
multinational and Russian businesses in each of the regions it services, as
well as medium and small-sized businesses. Between 1993 and mid-1996, consumer
prices in TeleRoss's industry increased significantly as a result of Rostelecom
raising its prices in an effort to raise capital for investment and development
of its network infrastructure, although prices have stabilized over the past
six months. During the year ended December 31, 1997, TeleRoss increased sales
to carriers, which sales were made at wholesale rates, resulting in a decrease
in the average rate per minute for TeleRoss. TeleRoss strategically prices its
domestic long distance services at a slight premium over similar services
offered by Rostelecom to account for a higher quality of service, but in line
with the prices offered by regional competitors.

    Sales and Marketing. TeleRoss markets its services to carriers and
businesses through direct sales channels. As of December 31, 1997, TeleRoss
employed 31 sales and marketing personnel, approximately half of which are
based in Moscow with the other half deployed regionally to identify and contact
prospective customers. The Moscow-based sales and marketing personnel are
organized into industry groups in order to better identify and serve customer
needs. Each region is typically served by one or two sales representatives.
TeleRoss's sales efforts are supported by market research and promotional
activities carried out at the joint venture level and tailored to the specific
market base of each region. TeleRoss's marketing strategy is to attract carrier
customers by focusing on those carriers with high volume minutes operating in
regions where TeleRoss has a competitive advantage. Through cross-marketing
agreements with Sovintel and Sovam, TeleRoss markets many of the other service
offerings of GTS's Russian businesses to customers throughout its service
regions. Billing functions and the monitoring of quality control and technical
issues are performed centrally through the Moscow-based hub.

    Ownership and Control. TeleRoss consists of the TeleRoss Operating Company,
and the 50% beneficially owned TeleRoss Ventures. GTS controls TeleRoss
Operating Company (which holds the network license) and co-manages the TeleRoss
Ventures under the terms of the applicable TeleRoss Ventures' foundation
agreements and charters. Under some of these charters, GTS generally has the
right to designate the Chairman of the board of directors, and GTS's local
partner has the right to designate the Deputy Chairman, for the first two-year
term (and thereafter GTS and the local partner nominate the Chairman and Deputy
Chairman for approval by the entire board on a rotating basis). The foundation
agreements and charters do not have expiration dates. While GTS has significant
influence within these ventures, decisions, including the decision to declare
and pay dividends, are generally subject to GTS's partner's approval. See
"--Certain Considerations Generally Applicable to the Company's Operations --
Dependence on Certain Local Parties; Absence of Control." Neither GTS nor its
respective joint venture partners are obligated to fund operations or capital
expenditures of the TeleRoss Ventures. Losses and profits are allocated to the
partners in accordance with their ownership percentages, in consideration of
funds at risk. As of December 31, 1997, GTS and its partners had each made
equity contributions aggregating $1.7 million to the various TeleRoss Ventures.
Contributions made by the partners include contributions of cash and intangible
assets, such as licenses. In addition, the various TeleRoss Ventures had
outstanding loans of $3.4 million to GTS as of December 31, 1997. In addition,
as of December 31, 1997, GTS had made equity contributions of $5.8 million to
the TeleRoss Operating Company and the TeleRoss Operating Company had
outstanding loans of $37.4 million to GTS. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Accounting
Methodology -- Profit and Loss Accounting."

SOVAM

    Sovam is a venture that is wholly owned by GTS. Sovam was founded in 1990
as a venture equally owned by GTS and the Institute for Automated Systems
("IAS"). In 1992, Cable & Wireless acquired a 33% ownership interest in Sovam,
which interest was subsequently acquired by GTS in 1994, bringing GTS's
ownership interest to 66.7%. GTS purchased IAS's interest in Sovam in February
1998, thereby making Sovam a wholly owned subsidiary of GTS. Sovam provides
high-speed data communications services, electronic mail and database access
over a high-speed packet/frame relay network in 30 major Russian and CIS
cities. Sovam also offers Russia On Line, the first Russian language Internet
service, which provides direct access to the Internet as well as access to a
wide range of local and international information services and databases.
(Russia On Line(TM) is a trademark of the Company.) As of December 31, 1997,
Sovam had approximately 1,571 data service customers and approximately 


                                      20
<PAGE>   21


3,960 Russia On Line customers. Sovam employed over 110 persons in Moscow and
other regions of the CIS as of December 31, 1997. Sovam provides equipment and
maintains marketing and technical support personnel at each location either
through its own infrastructure or through the infrastructure of TeleRoss.

    In addition to serving the Moscow and St. Petersburg markets, Sovam
co-locates its operations with the TeleRoss Ventures, offering its services in
all TeleRoss cities, and also serves 15 additional cities in Russia and the
CIS. Sovam operates under its own license within Russia while services
elsewhere in the CIS are provided through applicable local partner licenses.
The local partners of the TeleRoss Ventures provide facilities, assist in the
provision of leased lines to Sovam customers that allow them to connect with
Sovam's local data switches and also provide technical support. Sovam utilizes
Sovintel's international capabilities and, in TeleRoss-served locations,
TeleRoss's satellite overlay network, to take data through its local data
switches and over the leased lines to its customers. Customers may obtain
virtual private data networks without investing in, acquiring, installing and
maintaining their own network nodes and switches.

    The following table sets forth certain operating data related to Sovam's
operations:

(1) In addition to the subscribers included above, Sovam frequently connects
    potential Russia On Line subscribers on a complimentary one-month trial
    basis. As of December 31, 1997, there were approximately 800 such potential
    subscribers.

    Services. Sovam's service offerings are comprised of data services,
equipment and hardware sales and its Russia On Line services.

    o   Data Services. Sovam provided high speed connectivity, electronic mail,
        database access and fax services to approximately 1,571 customers as of
        December 31, 1997, in Russia and the CIS. Sovam customers can use
        electronic mail systems to send and receive messages and data and to
        access public and private data networks (including the Internet)
        worldwide. Customers may obtain virtual private data networks without
        investing in, acquiring, installing and maintaining their own network
        nodes and switches. In addition, Sovam offers its customers value-added
        data services. For example, Sovam offers "one-stop shopping" for
        hardware, software, installation and maintenance support and products
        such as "SovamMail," an e-mail service which allows customers to use
        Sovam's data network to send telex or facsimile messages to overseas
        recipients worldwide. Data services are currently available in 30
        cities throughout Russia and the CIS, including Moscow, St. Petersburg,
        each of the cities served by TeleRoss and some cities outside of the
        TeleRoss network.

    o   Equipment and Hardware Sales. Sovam sells communications equipment and
        hardware, and provides related installation, maintenance and support
        functions, to its customers. Sovam's primary customers in the equipment
        and hardware market are banking clients who use the equipment to
        interface with Sovam's network.



                                      21

    o   Russia On Line. Russia On Line is the first Russian language, as well
        as the first dual language, graphical user interface online service for
        accessing domestic and international information sources designed to
        appeal to a wide commercial audience. This service, which is
        distributed via GTS's domestic long distance infrastructure, provides
        customers with access to international databases (including the
        Internet), as well as an array of proprietary Russian and English
        language information services, such as news stories and market updates.
        Sovam had 3,960 Russia On Line subscribers (which includes
        approximately 800 trial subscribers) as of December 31, 1997. Sovam has
        developed a modified version of Netscape's Internet browser, which
        utilizes the Cyrillic alphabet, as part of its Russia On Line package.
        Sovam's enhanced Russian version of Netscape's browser is provided by
        Sovam to its customers under a distribution agreement with Netscape. In
        addition, Sovam has also entered into agreements with equipment
        manufacturers, including Dell, Motorola and Acer, to include Russia On
        Line software with their products.

    Customers and Pricing. Sovam's data communications customers consist
primarily of banking and financial services organizations and large
multinational companies, while Sovam's Russia On Line customers consist of a
wide variety of commercial enterprises. Sovam charges customers an installation
fee when service is commenced and a charge for any equipment which is
installed. Thereafter, customers are billed on a monthly basis for leased line
fees, port access charges and charges for data and Russia On Line services
rendered during the month. Data services are priced on a two-tier structure
with high volume users generally negotiating a flat-rate fee and lower volume
uses paying a volume-based fee which on average was $446 and $728 per
subscriber in 1996 and 1997, respectively. Russia On Line customers pay a fixed
monthly access charge plus an additional volume-based fee. Customers are billed
in dollars and payment is remitted in rubles and, to the extent permitted by
law, in dollars, with a 5% conversion fee added to ruble-denominated payments.

    Sales and Marketing. Sovam employs a dedicated sales and marketing force
comprised of 23 Russian nationals, 18 of which are based in Moscow with the
remainder deployed in the other Russian and CIS regions. Salespersons are paid
a fixed salary supplemented by sales commissions and performance-based bonuses.
Sovam's sale efforts are focused primarily on the banking and financial
communities and large multinational companies, although small and medium sized
entities are also emerging as potential Sovam customers. Bundled service
packages, which include Sovam's data and Internet service, Sovintel's
international service and TeleRoss's long distance service, are frequently
marketed together in order to offer customers a comprehensive
telecommunications solution. In addition to data communications services, Sovam
offers its customers hardware, installation and maintenance service and is a
distributor of Northern Telecom equipment.

    Ownership and Control. At December 31, 1997, GTS owned 66.7% of Sovam and
IAS owned the remaining 33.3%. GTS purchased IAS's interest in Sovam in
February 1998, thereby making Sovam a wholly owned subsidiary of GTS. As of
December 31, 1997, neither GTS nor IAS were obligated to fund Sovam's
operations or capital expenditures. Losses and profits of Sovam were allocated
to the partners in accordance with their ownership percentages, in
consideration of funds at risk. As of December 31, 1997, GTS and its partner
had made equity contributions of $1.3 million and $0.7 million, respectively,
to Sovam. In addition, Sovam had outstanding loans of $5.7 million to GTS as of
December 31, 1997. See "Management's Discussion and Analysis of Financial
Condition and Results of Operation -- Accounting Methodology -- Profit and Loss
Accounting."

GTS CELLULAR

    GTS Cellular operates three cellular businesses in Russia and Ukraine. In
Russia, GTS has a wholly owned subsidiary Vostok Mobile (which is organized in
The Netherlands), which currently operates twelve AMPS cellular companies in
Russian regions west of the Urals under the trade name Unicel. Vostok Mobile
owns between 50% and 70% of these cellular joint ventures (the "Unicel
Ventures") in Russia. In addition, GTS intends to enter into the cellular
markets of additional Russian regions through its Vostok Mobile venture. GTS
also participates in PrimTelefone, a 50% owned joint venture that operates an
NMT-450 network in Vladivostok and four other cities in the Primorsky region of
Russia. In Ukraine, GTS has an approximately 25% beneficial interest in
Bancomsvyaz which operates a DCS-1800 cellular network in Kiev, and an

    Vostok Mobile. Through Vostok Mobile, GTS currently operates twelve
cellular joint ventures in Russia. Vostok Mobile owns between 50% and 70%
interests in each of the twelve Unicel Ventures with regional telephone
companies and, in one instance, a private Russian company, owning the remaining
ownership interest. The Unicel Ventures each operate an AMPS-based cellular
network, which was chosen principally because of the lower licensing fees and
equipment costs associated with AMPS operations. The Company believes that the
Unicel Ventures' AMPS-based networks can be upgraded to digital AMPS ("D-AMPS")
for an incremental capital investment. Cellular networks which utilize digital
technology, such as D-AMPS, DCS and GSM offer several advantages over analog
technology including improved overall signal and sound quality, improved call
security, potentially lower incremental infrastructure costs for additional
subscribers and the ability to provide enhanced data transmission services,
such as facsimile and e-mail. Digital technology also provides increased system
capacity. The ventures intend to convert to D-AMPS at such time as there exists
sufficient competitive pressures and/or market demand for digital services to
merit the additional investment.

    AMPS technology is widely used by other cellular networks throughout
Russia, making roaming commercially feasible. The Unicel Ventures have entered
into roaming agreements with other AMPS-based cellular providers, which allow
their subscribers to manually roam throughout Russia. Manual roaming, as
opposed to automated roaming, requires subscribers to notify their local
cellular providers of their travel plans in order to receive roaming
capability. Vostok Mobile is currently working with VimpelCom to develop
automated roaming standards which will provide subscribers with automated
roaming capability.



                                      24

    The Unicel Ventures, collectively, are licensed to provide cellular service
to regions with an aggregate population of approximately 18.4 million people
and the cellular networks of these ventures cover populations of approximately
6.5 million people. Over the next five years, Vostok Mobile plans to expand the
coverage of the cellular networks to approximately 9.8 million people.

    The Unicel Ventures are the only cellular operators in many of their
respective regions. Each region, however, has the potential for three licensed
operators, including one operator for each of the AMPS, NMT and GSM cellular
standards, and the Company expects competition to increase in the future as the
Russian economy develops and telephony demands increase. Each of the Unicel
Ventures operates independently within uniform guidelines established by Vostok
Mobile. The Unicel Ventures employ local engineering and marketing personnel,
which helps the ventures maximize their presence in their respective markets
and maintain quality control. Vostok Mobile and its ventures employed over 330
persons as of December 31, 1997, with over 290 persons employed regionally.

    PrimTelefone. GTS's cellular operations in Vladivostok are conducted
through PrimTelefone, a 50% owned GTS subsidiary, with the local electrosviaz
owning the remaining 50%. PrimTelefone began operations in 1995 and operates an
NMT-450 network in Vladivostok and four other cities in the Primorsky region.
PrimTelefone entered and penetrated the Vladivostok market by leveraging its
network design and full interconnection with the city telephone network. As a
result, PrimTelefone's total subscriber base has grown to 6,152 (including
5,212 active subscribers) as of December 31, 1997 and PrimTelefone has been
able to capture approximately half of the Vladivostok cellular market.
PrimTelefone has also updated its billing system, which allows it to offer
automated roaming. Although PrimTelefone has experienced significant growth, it
does face competition. PrimTelefone's only current competitor has recently
upgraded its network for more complete coverage and has been fully
interconnected to the city telephone network and may prove to be more
competitive in the future. PrimTelefone employs approximately 60 persons which
include dedicated sales, marketing and customer service personnel.

    PrimTelefone holds a license to provide cellular service to a region having
a population of approximately 2.2 million people and, as of December 31, 1997,
its cellular network covered an area with a population of approximately 1.2
million people. PrimTelefone plans to expand its network's coverage to
approximately 1.7 million people over the next five years.

    Bancomsvyaz. GTS owns a 50% economic interest in an intermediate holding
company which holds an approximately 49% interest in Bancomsvyaz, giving GTS an
indirect approximately 25% economic interest in Bancomsvyaz. The remaining
approximately 51% interest in Bancomsvyaz is owned by Bancomservice, a private
company whose principals include telecommunications industry participants in
Ukraine, and a Ukranian national. Bancomsvyaz is co-managed by GTS and
Bancomservice, with Bancomservice appointing the General Director and GTS
appointing the Chief Operating Officer, Chief Financial Officer and two
Business Line directors. The current General Director has been active in the
development of the telecommunications industry in Ukraine. Through Bancomsvyaz,
GTS participates in the operation of a cellular network and an international
overlay network. With approximately 100 employees, Bancomsvyaz markets its
services and closely monitors technical and quality-related issues.

    Cellular network. Bancomsvyaz operates a cellular network in Kiev utilizing
DCS-1800 cellular technology, and operates under a cellular license that covers
the Kiev oblast. Bancomsvyaz began cellular operations in 1996 by covering the
city center of Kiev and expanded its coverage to include the entire city in
1997. Bamcomsvyaz currently provides automated roaming capability in the U.K.
and has entered into a clearinghouse agreement with a European PTO which
provides Bancomsvyaz customers with automated roaming capability with all GSM
signatories with a roaming agreement with this PTO.

    Bancomsvyaz holds a license to provide cellular service to a region having
a population of approximately 4.5 million people and, as of December 31, 1997,
its cellular network covered an area with approximately 2.5 million people.
Bancomsvyaz plans to expand its network's coverage to approximately 3.2 million
people over the next five years.

    Overlay network. Bancomsvyaz provides switched traffic service through its
overlay network in Kiev. Bancomsvyaz owns and operates a partitioned mobile
switch for both its overlay and cellular businesses. 


                                      25
<PAGE>   26

Bancomsvyaz has seven central offices in the city and also provides last mile
connections (which are primarily copper) from the central offices to customers.
Local traffic is routed to the local telephone network through the mobile
switch. International traffic is routed through a government-owned satellite
dish to the GTS-Monaco Access international gateway. Bancomsvyaz emphasizes its
high quality service and markets primarily to multinational companies, real
estate developers and hotels. Bancomsvyaz is also negotiating with Sovintel to
provide a link to Moscow and plans to offer VSAT-based connections to its
network in the future.

    Sales and Marketing. The GTS Cellular entities have entered into agreements
with local distributors to more effectively reach their target markets.
Particular emphasis is placed on product branding. Vostok Mobile's sales and
marketing efforts are focused on the branding of its trade name, Unicel, which
is marketed and promoted at the local level by each of the Unicel Ventures. By
promoting the Unicel trade name, local ventures can emphasize their
relationships with Vostok Mobile and the other Unicel Ventures, allowing
customers to view the Unicel Ventures as integrated parts of a large cellular
organization rather than as lone, independent operators.
Bancomsvyaz operates under the trade name Golden Telecom.

    Customers and Pricing. GTS Cellular's customers are primarily large,
mid-sized and start-up businesses and wealthy individuals. Increases in the
number of customers for GTS Cellular's ventures is typically linked to the
economic health of the region in which such venture operates. Cellular service
is generally a premium service in the cities in which GTS Cellular operates and
is priced as such. Each venture begins with two tariff plans, a "standard"
tariff plan and a "premium" tariff plan, which includes a fixed amount of
airtime at a discounted per-minute rate. Each plan prices late night and
weekend calls at off-peak rates. The Company expects that prices will decrease
as competition increases. Connection fees are minimized in order to reduce
license fees in AMPS regions (which are partially calculated by reference to
connection fees), as well as to keep market entry costs low. GTS Cellular has
benefited from high margins generated by the sale of handsets, which are marked
up in line with other cellular operators in Russia and the CIS. Value-added
services, such as call forwarding and conference calling, when available, are
priced nominally and discounted when sold in packages. Cellular accounts are
recorded in dollars and customers remit payment in rubles at the exchange rate
on the date of the bill and, in instances permitted by law, in dollars. Ruble
accounts generally are charged a two percent conversion fee and payments in
rubles are applied at the rate of exchange on the date of payment. In order to
lessen risks to its receivables, the Company and its cellular ventures require
advance payment from all customers with prepayments averaging approximately
$250 per customer or six to eight weeks of service.

    Ownership and Control. GTS Cellular's Russian operations (except for the
Vladivostok operations) are conducted through ventures that are owned between
50% and 70% by Vostok Mobile, a wholly owned subsidiary of GTS. GTS Cellular's
Vladivostok and Ukrainian operations are conducted through ventures which
require partner approval for most decisions. The applicable foundation
agreements and charters do not have expiration dates. See "--Certain
Considerations Generally Applicable to the Company's Operations -- Dependence
on Certain Local Parties; Absence of Control." Neither GTS nor any of its
respective partners in its Vladivostok or Ukrainian operations are obligated to
fund operations or capital expenditures. Losses and profits of all such
ventures are allocated to the partners in accordance with their ownership
percentages, in consideration of funds at risk. As of December 31, 1997, GTS
and its partners had made equity contributions aggregating $15.8 million and
$15.3 million, respectively, to the various GTS Cellular Ventures.
Contributions made by the partners include contributions of cash and intangible
assets, such as licenses. In addition, the various GTS Cellular Ventures had
outstanding loans of $25.0 million to GTS as of December 31, 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Accounting Methodology -- Profit and Loss Accounting."

        LICENSES AND REGULATORY ISSUES

     Telecommunications operators in Russia are nominally subject to the
regulations of the Regional Communications Committee (the "RCC"). As a
practical matter, national telecommunications authorities of the individual CIS
countries and certain regional and local authorities generally regulate
telecommunications operators in their markets through their power to issue
licenses and permits.



                                      26
<PAGE>   27

    The Communications Law sets out a comprehensive legal and regulatory
framework for the sector. It also sets forth general principles for the right
to carry on telecommunications activities, describes government involvement in
telecommunications regulation and operation, establishes the institutional
framework involved in regulation and administration of telecommunications, and
deals with various operational matters, such as ownership of networks,
protection of fair competition, interconnection, privacy and liability. This
institutional framework is implemented by separate legislation.

    Licenses to provide telecommunications services are issued by the MOC on
the basis of a decision by the Licensing Commission at the MOC. No new
licensing regulations have been issued since the enactment of the
Communications Law and in practice the MOC continues to issue licenses based on
the Licensing Regulations. Under the Licensing Regulations, licenses for
rendering telecommunications services may be issued and renewed for periods
ranging from 3 to 10 years and several different licenses may be issued to one
person. Once the licenses are received, the licensee is required to register
its right to hold and operate under the license with Gossvyaznadzor, the
national authority responsible for monitoring compliance with regulatory and
technical norms. Renewals may be obtained upon application to the MOC and
verification by appropriate government authorities that the licensee has
conducted its activities in accordance with the licenses. Officials of the MOC
have fairly broad discretion with respect to both the issuance and renewal
procedures. Both the Communications Law and the Licensing Regulations provide
that a license may not be transferred. However, regional authorities are
sometimes in a practical position to limit these national authorities. In
August 1995, the Russian government created Svyazinvest, a holding company, to
hold the federal government's interests in the majority of Russian local
telecommunications operators. Such entities at the oblast and krai levels
(administrative regions within Russia) and two cities -- Moscow and St.
Petersburg -- exercise significant control over their respective local
telephone networks.

    License procedures for the Company's cellular services include frequency
licensing from the MOC through a two step process. A license must first be
obtained from the MOC for permission to operate mobile cellular services on a
commercial basis in a specific standard and frequency bandwidth. Thereafter, an
approval to use specific frequencies within the band must be received from the
State Radio Frequencies Commission. Once the licenses are received,
Gossvyaznadzor confirms the rights of an operator to offer radio frequency
transmissions on specific frequencies, administers type acceptance procedures
for radio communications equipment and monitors compliance with licensing
constraints. In each instance, the Company is required to obtain additional
licenses and permits with respect to the use of equipment and the provision of
services.

    Telecommunications laws and regulations in Ukraine are similar in many
respects to those of Russia but are subject to greater risks and uncertainties.
Regulations currently prohibit foreign entities from directly owning more than
49% of any telecommunications operating company. GTS's Ukrainian joint venture
agreements provide it with the option of purchasing an additional one percent
of the cellular network if these rules are liberalized. The Ukrainian
government has proposed substantial frequency permit fees in connection with
providing GSM service in Ukraine, and has notified Bancomsvyaz that it has
levied a $2.9 million frequency license fee on Bancomsvyaz's cellular license.
At this time, the Company is formulating its response to the government's action
and expects that the authorities will grant a ninety-day extension for payment
of such fee. The Company does not believe the outcome will have a material
adverse effect on the Company. There can be no assurance that additional fees
will not be imposed in the future.

    GTS's subsidiaries and ventures hold the following licenses in Russia and
Ukraine:

    Switched Services. In Russia, the Company holds two licenses. The first
license was reissued to Sovintel in November 1996 and authorizes Sovintel to
operate as an international overlay network with the ability to interconnect
with the Moscow region and St. Petersburg public switched telecommunications
network ("PSTN"). This license ultimately requires Sovintel to provide service
to at least 50,000 subscribers and expires in May 2000. It was amended in
February 1997 to cover the Leningrad region. The second license was reissued to
SFIT, Ltd., a wholly-owned subsidiary of GTS in February 1997, for provision of
intercity services in 39 regions and in Moscow with ability to interconnect
with the PSTN. In Kiev, Ukraine, the company holds a license for provision of
overlay network services, including international services, in the name of its
affiliate, Bancomsvyaz. In addition, Sovintel is an ITU recognized private
operating agency ("RPOA"), which enables it to maintain a separate dialing code
(7-501)


                                      27
<PAGE>   28

that can be directly dialed from over 170 countries. Sovintel's status as an
RPOA also enables it to terminate calls directly with other operators. Leased
Circuits. In September 1996 the MOC issued to Sovintel a five-year license to
lease local, intercity and international circuits in the territory of Moscow,
Moscow region and St. Petersburg, valid until September 2001. The total number
of circuits leased is approximately 444 and may be increased up to a total
authorized capacity of 2,500.

    Data Services. In August 1996, the MOC reissued to Sovam a 2 1/2-year
license, effective July 1996, to provide data transmission services via a
dedicated network to a number of oblasts and other regions covering a large
portion of Russia. The license permits a network capacity of not less than
5,000 customers, allows it to interconnect with other data transfer networks in
Russia, and expires January 1, 1999. The Company's purchase of IAS's 33.3%
interest in Sovam requires that Sovam re-register its license. The Company
expects that the license will be re-registered.

    Local Access Services. In January 1997, the MOC has licensed TCM to provide
local telephone service in Moscow to not less than 100,000 subscriber local
access lines. The license expires in May 2006. TCM has an agreement with MGTS
to provide up to 200,000 lines, which would require an extension to its
license, when its current capacity is reached.

    Cellular Services. In connection with cellular operations, Russian law
apportions the responsibility for regulating and licensing cellular businesses
between national and regional regulators. National telecommunications
regulators have been assigned the responsibility of regulating and licensing
cellular businesses utilizing the GSM and NMT-450 cellular standards prevalent
in Europe. These regulators have auctioned licenses to provide these services
to a number of ventures that have included large, well capitalized western
telecommunications providers such as U S WEST and Nokia during the last four
years. Regional telecommunications authorities have been given the rights to
supervise the observance of licenses by cellular businesses utilizing AMPS
cellular standard service, which is prevalent in the United States. However,
AMPS licenses are issued by the MOC. GTS believes that, in many instances,
cellular operators obtaining AMPS standard licenses, particularly those in
second tier cities, pay license fees that are lower than those paid for the GSM
and NMT-450 "national standards". Licenses for cellular providers have a term
of approximately 10 years.

    The Company's twelve Russian cellular companies have licenses which expire
between 2005 and 2007. One of the companies initially received an operating
license in 1994, six companies initially received an operating license in 1995
and five companies initially received an operating license in 1996.

    Bancomsvyaz holds a license for provision of DCS-1800 mobile services in
the Kiev oblast.

COMPETITION

    Overview. GTS faces significant competition in virtually all of its
existing telecommunications businesses in the CIS. Many of the Company's
competitors and potential competitors, which include large multinational
telecommunications companies, have substantially greater financial and
technical resources than the Company and have the ability to operate
independently or with global or local partners and to obtain a dominant
position in these markets. The Company believes that it has a competitive
advantage in each of these markets because of its operating history, its
ability to bundle a broad range of telecommunications services in the region
and its ability to make rapid decisions in pursuing new business opportunities
and addressing customer service needs. The Company also believes that its local
partnerships and reliance on nationals in the management of its businesses and
joint ventures provide it with better knowledge of local political and
regulatory structures, cultural awareness and access to customers.

    International Services. Sovintel faces significant competition from more
than ten other existing service providers in Moscow, including Rostelecom and
joint ventures between local parties and multinational telecommunications
providers. Large competitors include the "Combellga" joint venture, an RPOA
operator in which Alcatel and the Belgian PTO participate as foreign investors,
"Comstar", a joint venture between GPT Plessey 



                                      28
<PAGE>   29


and MGTS, providing services similar to those provided by the Company, TelMos,
a joint venture between AT&T, MGTS, Global One, through its Moscow based
ventures, and Peterstar, in Petersburg, which is part of the PLD Telekom group.
Several smaller companies, such as DirectNet, and Aerocom provide high-volume
and carrier's carrier services in Moscow. Bancomsvyaz competes in the switched
international traffic market with the Kiev electrosviaz and UTel, a joint
venture that includes Western partners with substantial capital and technical
resources who together hold a dominant share of the Kiev market. The Company
expects that market consolidation will take place among the competitive field
in international services.

    Domestic Long Distance Services. The Company believes its major competitors
in the Russian domestic long distance market consist of Rostelecom, the
electrosviazs, including those which are partners in the Company's TeleRoss
Ventures, and a variety of ventures that include foreign partners with
substantial financial resources. The most significant of such competitors
include: Global One, through its regional operations; Rustel, a venture that
includes Rostelecom, other Russian partners and International Business
Communication Systems, a Massachusetts telecommunications firm; Belcom, a
private company in which Comsat has a majority interest and which provides VSAT
services primarily to the energy sector; Satcom, a Russian joint venture
licensed to provide local, long distance and international service over private
and public switched networks; Teleport TP, a satellite overlay company jointly
owned by Rostelecom and Petersburg Long Distance that provides satellite
teleports in cities throughout Russia; and Comincom, a Russian private venture.
In the Russian far east, TeleRoss competes with Vostok Telecom, which is owned
by the Japanese companies KDD and NIC and certain Russian partners; and
Nakhodka Telecom, which is owned by Cable & Wireless and certain Russian
partners.

    GTS both cooperates and competes with Rostelecom. Rostelecom provides only
international and long distance services to international carriers and regional
electrosviazs, and does not provide end-to-end customer services. GTS provides
last mile, account management, and transit services for Rostelecom in Moscow,
and uses Rostelecom channels and switches for both international and long
distance services. GTS provides long distance and international services on an
end-to-end basis, using service elements of Rostelecom, the electrosviazs and
its own resources. However, Rostelecom does compete with Teleross, in that
Teleross provides intercity services to customers, using satellite channels
provided by other state agencies (Intersputnik), and provides transit services
to various electrosviazs, on a traffic overflow basis.

    GTS believes that it enjoys a number of competitive advantages in the
Russian domestic long distance market, the most important being the maturity of
its international and data service businesses in Russia. This provides GTS with
access to the services, customers, products, licenses and facilities of its
other businesses. The Company also believes that it has more experienced
management, a more comprehensive strategy to build out a nationwide long
distance network and stronger relationships with many regional telephone
companies and with satellite capacity providers, such as Intersputnik, than
most of its competitors. In addition, the Company believes that it does not
have any significant competitor in the regional inter-city market (i.e., calls
between Russian cities other than Moscow or St. Petersburg).

    Data Services. Sovam has several primary competitors in the market for data
services: Global One, which began packet-switched service in Moscow and St.
Petersburg in June 1992, under the Sprint Networks venture; Demos, an Internet
service provider; and Relcom, a cooperative affiliation of computer users that
relies on an older generation of technology that supplies slower and lower-cost
messaging facilities to customers (primarily domestic commodities traders) that
do not require higher levels of service. In addition MCI and Rostelecom have
recently announced their agreement to create a national Internet access network
utilizing Rostelecom's domestic network and MCI's international infrastructure.
Rostelecom has also announced the formation of a new Internet services company
called RTK Internet, with Relcom as its partner. Although Sovam's business has
grown quickly, the Company believes that Global One is the market leader. GTS
believes that other potential competitors, including foreign PSTNs, Infotel,
Infocom and Glasnet, are also active in this market.

    Although the Company faces significant competition in this market, it
believes that it enjoys certain competitive advantages, including the ability
to reach a wide area throughout Russia through TeleRoss, innovative service
offerings such as Russia On Line, the maturity of its business in the key
banking services segment, high levels of customer service and support, and high
speed digital channels through TeleRoss.



                                      29
<PAGE>   30

    Local Access Services. The Company believes that its major competition in
the Moscow local access market consists of a number of ventures with Western
partners, including Telmos (which includes AT&T), Comstar (which includes GPT
Plessey), and Combellga. However, since TCM has obtained an allocation of up to
100,000 numbers, the Company believes that TCM will account for a substantial
proportion of the new capacity to come onto the market within the next five
years.

    Cellular Services. Most Russian cellular markets have the potential for
three licensed operators, including one operator for each of the GSM and
NMT-450 cellular standards, which Russia has adopted as national standards, and
one operator using the AMPS cellular standard, which has been set as a regional
standard. Many large Western telecommunications operators, including U S WEST,
Deutsche Telekom, STET, Midcom and Millicom, have participated in auctions for
licenses to provide GSM and NMT-450 cellular service to certain significant
Russian urban centers. In addition, a CDMA auction is likely to occur in the
future which could result in one or more CDMA operators entering the market. In
Ukraine, Bancomsvyaz competes primarily with an NMT operator and a GSM operator
in Kiev. Additional GSM licenses were auctioned off in early 1997 and other GSM
operators may enter other markets in 1998.

CERTAIN CONSIDERATIONS APPLICABLE TO THE COMPANY'S OPERATIONS IN RUSSIA 
AND THE CIS

    Substantially all of the Company's revenue is derived from operations in
Russia and the CIS. Foreign companies conducting operations in the former
Soviet Union face significant political, economic, and legal risks.

    Political. The political systems of Russia and the other independent
countries of the CIS, which are in a stage of relative infancy, are vulnerable
to instability due to the populace's dissatisfaction with reform, social and
ethnic unrest and changes in government policies. Such instability could lead
to events that could have a material adverse effect on the Company's operations
in these countries. In recent years, Russia has been undergoing a substantial
political transformation. During this transformation, legislation has been
enacted to protect private property against expropriation and nationalization.
However, due to the lack of experience in enforcing these provisions in the
short time they have been in effect and due to potential political changes in
the future, there can be no assurance that such protections would be enforced
in the event of an attempted expropriation or nationalization. Expropriation or
nationalization of the Company, its assets or portions thereof, whether by an
outright taking or by confiscatory tax or other policies potentially without
adequate compensation, would have a material adverse effect on the Company.

    The various government institutions and the relations between them, as well
as the government's policies and the political leaders who formulate and
implement them, are subject to rapid and potentially violent change. For
example, the Constitution of the Russian Federation gives the President of the
Russian Federation substantial authority, and any major changes in, or
rejection of, current policies favoring political and economic reform by the
President may have a material adverse effect on the Company. In March 1998,
President Yeltsin dismissed his entire cabinet, including Prime Minister Victor
Chernomyrdin, citing, among other things, a need for more dynamism and
initiative in the Russian government. It was unclear, however, how the change
will affect governmental policy and constitutional issues, including the
identity of President Yeltsin's successor if he were not to survive his term of
office. In addition, it was uncertain whether the resolution of these and other
issues could have a material adverse effect on the Company.

    Furthermore, the political and economic changes in Russia have resulted in
significant dislocations of authority. The local press and international press
have reported that significant organized criminal activity has arisen and high
levels of corruption among government officials exist where the Company
operates. While the Company does not believe it has been adversely affected by
these factors to date, no assurance can be given that organized or other crime
will not in the future have a material adverse effect on the Company.

    Economic. Over the past five years the Russian government has enacted
reforms to create the conditions for a more market-oriented economy. Despite
some progress in implementing its reforms, including progress in reducing
inflation and stabilizing the currency and industrial production, there remains
generally rising unemployment and underemployment, high government debt
relative to gross domestic product and high levels of corporate insolvency.


                                      30
<PAGE>   31

No assurance can be given that reform policies will continue to be implemented
and, if implemented, will be successful, that Russia will remain receptive to
foreign trade and investment or that the economy will improve.

    In addition, Russia, the CIS and other emerging countries in which the
Company operates currently receive substantial financial assistance from
several foreign governments and international organizations. To the extent any
of this financial assistance is reduced or eliminated, economic development in
Russia, the CIS and such other countries may be adversely affected.

    Russian and CIS businesses have a limited operating history in
market-oriented conditions. The relative infancy of the business culture is
reflected in the Russian banking system's under-capitalization and liquidity
crises. There have been concerns about rumors that many Russian banks continue
to have cash shortages. The Russian Central Bank has reduced banks' reserve
requirements in order to inject more liquidity into the Russian financial
system, but has stressed that it will not bail out the weaker banks. Many of
these banks are expected to disappear over the next several years as a result
of bank failure and anticipated consolidation in the industry. A general
Russian banking crisis could have a material adverse effect on the Company's
operations and financial performance and on the viability of the Company's
receivables.

    Regulation of the Telecommunications Industry. The Russian
telecommunications system is currently regulated largely through the issuance
of licenses. There is currently no comprehensive legal framework with respect
to the provision of telecommunications services in Russia, although a number of
laws, decrees and regulations govern or affect the telecommunications sector.
As a result, ministry officials have a fairly high degree of discretion to
regulate the industry. Although telecommunication licenses may not be
transferred under Russian law, the Russian MOC has adopted the position that
licensees may enter into agreements with third parties in connection with the
provision of services under the licensee's license; however, the MOC does not
generally review agreements entered into by licensees. There can be no
assurances that the current or future regulation of the Russian
telecommunications systems will not have a material adverse effect on the
Company.

    Current Russian legislation governing foreign investment activities does
not prohibit or restrict foreign investment in the telecommunications industry.
However, on February 28, 1997, the State Duma, the lower house of parliament,
approved, on the first reading, draft foreign investment legislation which
would restrict any significant future foreign investment in numerous sectors of
the Russian economy, including telephone and radio communications. It is
unlikely that such restrictive legislation will be enacted, unless the
political climate changes dramatically. See "-- Political." More likely is the
emergence of restrictions on foreign investment in strategic industries, which
could result in foreign ownership limitations in industries such as
telecommunications which are not uncommon in many countries. The draft
legislation has been referred to the Russian government for comment. For such
draft legislation to become Federal law, it must be passed by a majority vote
of the State Duma at another two readings, then be approved by a majority of
the Federation Council, the upper house of parliament, and signed by the
President of the Russian Federation. Rejection of such legislation by the
Federation Council can be overridden by a two-thirds majority of the State
Duma. Rejection of such legislation by the President can be overridden by a
two-thirds majority of each of the Federation Council and the State Duma. As of
March 1998, there had not been any readings of the draft legislation beyond the
first reading. There can be no assurance that future regulation of foreign
investment in the telecommunications industry will not have a material adverse
effect on the Company.

    In addition, a lack of consensus exists over the manner and scope of
government control over the telecommunications industry. Because the
telecommunications industry is widely viewed as strategically important to
Russia, there can be no assurance that recent government policies liberalizing
control over the telecommunications industry will continue. Any change in or
reversal of such governmental policies could have a material adverse effect on
the Company. See "-- Russia and the CIS -- Licenses and Regulatory Issues."

    Legal Risks. As part of the effort to transform their economies into more
market-oriented economies, the Russian and other CIS governments have rapidly
introduced laws, regulations and legal structures intended to give participants
in the economy a greater degree of confidence in the legal validity and
enforceability of their obligations. Risks associated with the legal systems of
Russia and the other independent republics of the CIS include


                                      31
<PAGE>   32

(i) the untested nature of the independence of the judiciary and its immunity
from economic, political or nationalistic influence; (ii) the relative
inexperience of judges and courts in commercial dispute resolutions and
generally in interpreting legal norms; (iii) inconsistencies among laws,
presidential decrees, government resolutions and ministerial orders; (iv)
frequently conflicting local, regional and national laws, rules and
regulations; (v) the lack of legislative, judicial or administrative guidance
on interpreting the applicable rules; and (vi) a high degree of discretion on
the part of government authorities and arbitrary decision making which
increases, among other things, the risk of property expropriation. The result
has been considerable legal confusion, particularly in areas such as company
law, commercial and contract law, securities and antitrust law, foreign trade
and investment law and tax law. Accordingly, there can be no assurance that the
Company will be able to enforce its rights in any disputes with its joint
venture partners or other parties in Russia or the CIS or that its ventures
will be able to enforce their respective rights in any disputes with partners,
customers, suppliers, regulatory agencies or other parties in Russia or that
the Company can be certain that it will be found to be in compliance with all
applicable laws, rules and regulations.

    Russia has adopted currency and capital transfer regulations designed to
prevent the flight of capital from its borders. These regulations require
certain licenses for the movement of capital, which includes the incurrence and
repayment of indebtedness and the payment of capital contributions in foreign
exchange to Russian entities. The Company is resolving licensing issues with
respect to certain intercompany loans and capital contributions with the
applicable government agencies and believes that any licensing irregularities
that may arise will not have a material adverse effect on its financial
condition or results of operations. There can be no assurance, however, that
Russian government authorities will not take an unexpected adverse position
which could materially adversely affect the Company's business.

    Taxes. Generally, taxes payable by Russian companies are substantial. In
addition, taxes payable by Russian companies are numerous and include taxes on
profits, revenue, assets and payroll as well as value-added tax ("VAT").
Moreover, statutory tax returns of Russian companies are not consolidated and
therefore, each company must pay its own Russian taxes. Because there is no
consolidation provision, dividends are subject to Russian taxes at each level.
Currently, dividends are taxed at 15% and the payor is required to withhold the
tax when paying the dividend, except with respect to dividends to foreign
entities that qualify for an exemption under treaties on the avoidance of
double taxation. To date, the system of tax collection has been relatively
ineffective, resulting in the continual imposition of new taxes in an attempt
to raise government revenues. This history, plus the existence of large
government budget deficits, raises the risk of a sudden imposition of arbitrary
or onerous taxes, which could adversely affect the Company.

    Because of uncertainties associated with the laws and regulations of the
Russian tax system and the increasingly aggressive interpretation, enforcement
and collection activities of the Russian tax authorities, the Company's Russian
taxes may be in excess of the estimated amount expensed to date and accrued on
the Company's balance sheets. It is the opinion of management that the ultimate
resolution of the Company's Russian tax liability, to the extent not previously
provided for, will not have a material adverse effect on the financial
condition of the Company. However, depending on the amount and timing of an
unfavorable resolution of this contingency, it is possible that the Company's
future results of operations or cash flows could be materially affected in a
particular period.

    In various foreign jurisdictions, the Company is obligated to pay VAT on
the purchase or importation of assets, and for certain other transactions. In
many instances, VAT can be offset against VAT which the Company collects and
otherwise would remit to the tax authorities, or may be refundable. Because the
law in some jurisdictions is unclear, the local tax authorities could assert
that the Company is obligated to pay additional amounts of VAT. In the opinion
of management, any additional VAT which the Company may be obligated to pay
would not be material.

Exchange Controls and Repatriation Risks Relating to Russian Securities

    Russia has adopted currency and capital transfer regulations designed to
prevent the flight of capital from its borders. These regulations require
certain licenses for the movement of capital, which includes the incurrence and


                                      32

<PAGE>   33
repayment of indebtedness and the payment of capital contributions in foreign
exchange to Russian entities. The Company is resolving licensing issues with
respect to certain intercompany loans and capital contributions with the
applicable government agencies and believes that any licensing irregularities
that may arise will not have a material adverse effect on its financial
condition or results of operations. There can be no assurance, however, that
Russian government authorities will not take an unexpected adverse position
which could materially affect the Company's business.

    No assurance can be given that Russian foreign investment and currency
legislation will continue to permit repatriation of the proceeds from
investments. Furthermore, no assurance can be given that further restrictions
will not be imposed on the conversion of ruble earnings into foreign currency
for purposes of making dividend payments or on the repatriation of profits. If
any such further restrictions were imposed, they would have a material adverse
effect on the Company's interests in Russia.

    In Russia, where the Company derives most of its revenue, the ruble has
generally experienced a steady depreciation relative to the U.S. Dollar over
the past three years, although there has been some instability in the ruble
exchange rate over this period of time. The Company's tariffs are denominated
in U.S. Dollars but charges are invoiced and collected in rubles, while the
Company's major capital expenditures are generally denominated and payable in
various foreign currencies. To the extent such major capital expenditures
involve importation of equipment and the like, current law permits the Company
to convert its ruble revenues into foreign currency to make such payments. The
ruble is generally not convertible outside Russia. A market exists within
Russia for the conversion of rubles into other currencies, but it is limited in
size and is subject to rules limiting the purposes for which conversion and
payment may be effected. The limited availability of other currencies may tend
to inflate their values relative to the ruble and there can be no assurance
that such a market will continue to exist indefinitely. Moreover, the banking
system in Russia is not yet as developed as its Western counterparts and
considerable delays may occur in the transfer of funds within, and the
remittance of funds out of, Russia. Any delay in converting rubles into a
foreign currency in order to make a payment or delay in the transfer of such
foreign currency could have a material adverse effect on the Company. In
addition, since November 1997, Russian monetary authorities have pegged the
ruble/U.S. dollar exchange rate to fluctuate within a certain narrow range. It
is uncertain whether the Russian authorities will be able to maintain this
exchange rate and there can be no assurance that there will not be a
significant and sudden decline in the value of the ruble. Such a devaluation of
the ruble could have a material adverse effect on the Company and its results
of operations and on the Russian economy generally.

Dependence on Key Personnel

    The Company believes that its growth and future success will depend in
large part upon the efforts of a small number of key executive officers, as
well as on its ability to attract and retain highly skilled and qualified
personnel to work in the emerging markets in which it operates, particularly in
Russia and the CIS. The competition for qualified personnel in the
telecommunications industry is intense, particularly in emerging markets where
the Company operates and, accordingly, there can be no assurance that the
Company will be able to hire and retain qualified personnel. Although the
Company believes it has maintained a strong management team, there can be no
assurance as to what effect such personnel changes will have on the Company's
operations in Russia and the CIS.

WESTERN EUROPE

OVERVIEW

    GTS seeks to position itself as the leading independent carriers' carrier
within Western Europe through the development of two ventures, HER and
GTS-Monaco Access. HER's objective is to become the leading pan-European
carriers' carrier by providing centrally managed cross-border telecommunications
transmission capacity to telecommunications companies including traditional PTOs
and New Entrants on an approximately 18,000 kilometer high capacity fiber optic
network designed to interconnect a majority of the largest Western and Central
European cities. As of April 1, 1998, HER's network will link Brussels, Antwerp,
Rotterdam, Amsterdam, London,Paris, and Frankfurt. HER expects the initial five
country network and Switzerland to be placed in operation in the second quarter
of 1998. This



                                      33

<PAGE>   34

segment of the network is expected to deliver managed transport services over
approximately 3,800 kilometers of fiber optic cable linking the cities of
London, Rotterdam, Amsterdam, Antwerp, Brussels, Paris, Dusseldorf, Frankfurt,
Stuttgart, Munich, Geneva and Zurich. The full 18,000 kilometer network is
expected to become fully operational during the year 2000. HER also plans to
lease capacity on a transatlantic cable linking the European network with North
America and is exploring various interconnectivity options to Russia and Asia.
Such intercontinental interconnectivity will help HER satisfy the needs of its
European customers with respect to outgoing traffic and attract additional
non-European customers with traffic terminating in Europe. HER commenced
commercial service over the Brussels-Amsterdam portion of the network in late
1996, and the London-Paris portion in November 1997. GTS-Monaco Access operates
an international gateway in Monaco in partnership with, and utilizing the
existing gateway infrastructure of, the Principality of Monaco and provides
transit and routing of international calls to other telecommunications
operators. Through its HER and GTS-Monaco Access ventures, GTS is building a
new network for transporting voice, data and multimedia/image traffic for other
carriers throughout Western and Central Europe and for worldwide international
voice, data and multimedia/image traffic that either originates or terminates
in, or transits through, Western and Central Europe.

    The Company believes that the international segment of the Western and
Central European telecommunications market will be an attractive market for new
telecommunications entrants because of its large size, the high operating costs
and low productivity of current providers, and the barriers to entry created by
the need to control a network and its rights-of-way.

    The European telecommunications market has historically been dominated by
monopoly PTOs. This system has ensured the development of broad access to
telecommunications services in Europe, but it has also restricted the growth of
high quality and competitively priced pan-European voice and data services. The
current liberalization occurring in Europe is intended to address these
structural deficiencies by breaking down PTO monopolies, allowing new
telecommunications operators to enter the market and increasing the competition
within the European telecommunications market. In March 1996, the European
Commission adopted a directive (the "Full Competition Directive") requiring the
full liberalization of all telecommunications services in most EU member states
by January 1, 1998. The Company expects that full liberalization in these
European countries will lead to the emergence of New Entrants with new and
competitive service offerings. HER expects this increase in competition will
result in lower prices and a substantial increase in the volume of traffic and
range of telecommunication services provided. HER believes that as a result of
the increased call volume and growth in value added services, participants in
these markets will require significant amounts of new cross-border
telecommunications transport capacity to provide their services.

    The Hermes network will offer PTOs and New Entrants an attractive
alternative for the transport of cross-border European telecommunications
traffic. In the traditional system, PTOs own and control circuits only within
their national borders, and as a result, cross-border traffic must be passed
from one PTO to another PTO at the national boundary. No single PTO therefore
owns or controls end-to-end circuits for cross-border calls. The alternative
for carriers of this traffic will be to build their own transport capacity or
use International Private Leased Circuits ("IPLCs") which are provisioned by
combining half-circuits on the networks of two or more PTOs. The Company
believes that there are a number of problems with these options that result in
HER being well-positioned to become the leading independent carriers' carrier
in Western and Central Europe. In particular, building their own transport
capacity is unlikely to be an attractive option for most carriers because of
the high traffic volumes required to justify the expense, the need to focus
resources on marketing and customer service, the time commitment and the
regulatory and administrative complexities involved, particularly in obtaining
the rights of way across national borders. Likewise, IPLCs provided by the PTOs
also have a number of disadvantages, including high prices, lack of end-to-end
quality control, lack of redundancy, low quality due to diversity of network
systems and equipment, limited availability of bandwidth and long lead times
for provisioning.

    HER

    HER's objective is to become the leading pan-European carriers' carrier by
providing centrally managed cross-border telecommunications transmission
capacity to telecommunications companies including PTOs and New Entrants. HER
intends to offer these target customers a better transport system than is
currently available in Europe 


                                      34



<PAGE>   35

with a higher and more consistent level of transmission quality, redundancy,
network functionality and service across Europe at lower prices. Development of
the HER network is dependent upon, among other things, HER's continuing ability
to obtain the necessary financing, rights-of-way, licenses and other regulatory
approvals in a timely and cost-effective manner.

    HER is developing an approximately 18,000 kilometer, pan-European high
capacity fiber optic network designed to interconnect a majority of the largest
Western and Central European cities. Each access point of the network will be
placed in operation as it is linked to the network. HER intends to build the
network using the most accessible and cost-efficient infrastructure base in
each of the regions served, including using rights-of-way and existing
infrastructure of railways, motorways, pipeline companies, waterways and power
companies. HER plans a flexible approach to the network build-out plan and
intends to fine-tune the scope, route and design of the network based upon the
evaluation of customer demand. Historically, HER has experienced substantial
delays in concluding these agreements and developing its network. There can be
no assurance that HER will be successful in concluding necessary agreements, or
that delays in concluding such agreements will not materially and adversely
affect the speed or successful completion of the network. The successful and
timely completion of the network will also depend on, among other things, (i)
the availability to HER of substantial amounts of additional capital and
financing, (ii) timely performance by various third parties of their
contractual obligations to engineer, design and construct portions of the
network and (iii) HER's ability to obtain and maintain applicable governmental
approvals.

    HER expects to roll out full telecommunications service over the initial
five country network and Switzerland in the second quarter of 1998, as
discussed below, and the 18,000 kilometer network to be operational during the
year 2000. Although HER believes that its cost estimates and the build-out
schedule are reasonable, there can be no assurance that the actual construction
costs or time required to complete the network build-out will not substantially
exceed current estimates. Any significant delay or increase in the costs
associated with development of the HER network could have a material adverse
effect on HER and the Company.

    HER expects to continue to roll-out full telecommunications transport
service on the initial network in the first five countries and Switzerland
linking the additional cities of Dusseldorf, Stuttgart, Munich, Zurich and
Geneva by June 30, 1998. This initial network is expected to consist of
approximately 3,800 kilometers of fiber optic cable covering countries which,
in 1995, originated over 60% of all outgoing calls and terminated over 60% of
all incoming calls in the countries to be served by the full network. HER's
Network Operations Center located in Brussels, Belgium and its backup center
located in Antwerp, Belgium are fully operational and house network management
and customer support services which operate 24 hours a day, seven days a week.
Billing and customer service functions are also operational. Network coverage
is planned to be expanded to include the cities Berlin, Stockholm, Copenhagen,
and Milan in the third quarter of 1998. By the year 2000, the 18,000 kilometer
HER network is expected to have points of presence in at least 33 cities in 15
European countries, including Southern and Central Europe. HER also plans to
lease capacity on a transatlantic cable linking the European network with North
America and is exploring various interconnectivity options to Russia and Asia.

    HER has entered into agreements for the construction and/or lease of fiber
optic routes for the initial network in the first five countries. Contracts
have been concluded with respect to the portion of the network connecting
Germany with each of France, the Netherlands and Switzerland. Additional
contracts have been concluded in Switzerland, Denmark, Sweden, Spain and Italy.
HER continues to negotiate rights-of-way and other infrastructure arrangements
in order to extend its network in Western Europe. HER will need to negotiate
similar agreements to complete the network in four Central European countries.
Buildout of the HER network is subject to numerous risks and uncertainties that
could delay deployment or increase the costs of the network, or make the
network commercially unfeasible.

    Development of the HER network is capital intensive. Management expects
that approximately $290 million in capital expenditures will be incurred in
connection with the buildout of the HER network, with approximately $35 million
required for the roll out of the initial five country network that is expected
to be completed in the second quarter of 1998. While HER raised approximately
$265 million in a private placement of its senior notes in August 1997 (of
which $56.6 million has been placed in escrow for the first two years' interest
payments on the notes), additional financing may need to be obtained to
construct the HER network and there can be no assurance that such 



                                      35
<PAGE>   36

additional financing will be completed. Failure to obtain necessary financing
may require HER to delay or abandon its plans for deploying the remainder of
the network and would adversely affect the viability of HER, or may require the
Company to make additional capital contributions to HER at the expense of the
Company's other operations, either of which could have a material adverse
effect on the operations of the Company. HER's revenues and the cost of
deploying its network and operating its business will depend upon a variety of
factors including, among other things, HER's ability to (i) effectively and
efficiently manage the expansion of its network and operations, (ii) negotiate
favorable contracts with suppliers, (iii) obtain additional licenses,
regulatory approvals, rights-of-way and infrastructure contracts to complete
and operate the network, (iv) access markets and attract sufficient numbers of
customers and (v) provide and develop services for which customers will
subscribe. HER's revenues and costs are also dependent upon factors that are
not within HER's control such as regulatory changes, changes in technology,
increased competition and various factors such as strikes, weather and
performance by third-parties in connection with the development of the network.
Due to the uncertainty of these factors, actual costs and revenues may vary
from expected amounts, possibly to a material degree, and such variations would
likely affect HER's future capital requirements. HER must obtain additional
infrastructure provider 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 build out the network. There can be
no assurance that HER will be able to maintain all of its existing agreements,
rights and permits or to obtain and maintain the additional agreements, rights
and permits needed to implement its business plan on acceptable terms. Loss of
substantial agreements, rights and permits or the failure to enter into and
maintain required arrangements for the HER network could have a material
adverse effect to enter on HER's business. In addition, HER depends on third
parties for leases of dark fiber for substantial portions of its network. There
can be no assurance that HER will be able to enter into and maintain required
arrangements for leased portions of the HER network, which could have a
material adverse effect on HER's business.

    HER was formed on July 6, 1993 by HIT Rail B.V. ("Hit Rail"). Hit Rail was
incorporated in 1990 by eleven national railways to carry out
telecommunications engineering activities in order to construct and exploit a
data communications network for railway traffic. GTS-Hermes, Inc., a Delaware
corporation ("GTS-Hermes") purchased a 34.4% interest in HER in 1994 and has
increased its interest to 50% in 1995 and to 79% in 1997. In March 1998,
GTS-Hermes increased its ownership of HER to 89% by purchasing a portion of Hit
Rail's ownership interest in HER. GTS-Hermes is a wholly owned subsidiary of 
GTS.

Business and Marketing Strategy

    The overall strategy of HER is to offer PTOs and New Entrants pan-European
cross-border telecommunications transport services to help them, in turn, more
successfully meet the needs of their end-user customers. The HER network also
provides a vehicle through which a carrier can compete in markets where it does
not own infrastructure. HER expects to enter the market ahead of similar
competition and encourage a wide variety of carriers to use its network with
service offerings that meet their needs. HER's primary service offerings are
large-capacity circuits for "wholesale" customers such as PTOs and New
Entrants. HER's focus on carriers is designed to complement and not compete
with carriers' own business objectives in providing services to end-users.

    To establish HER as the leading carriers' carrier for international
telecommunications within Europe, HER offers its customers significantly higher
quality transmission and extended/advanced network capabilities at a
competitive price by focusing on the following:

        High Capacity International Network Facilities. The HER network is
    designed to offer its customers access to high capacity network facilities
    outside their domestic markets, providing cross-border capabilities without
    requiring customers to invest in network infrastructure or being
    constrained by a narrow range of capacity offerings. With STM-64 technology
    and Wavelength Division Multiplexing ("WDM") upgrades, HER's fiber
    deployment plan provides for the equivalent of 128 fiber pairs of capacity
    across Europe.

        Uniform Network Architecture. The HER network is designed to offer
    managed transport services from country to country and across multiple
    countries utilizing a single uniform network, in contrast to services
    currently available that use multiple providers over several networks with
    varying technologies and each under


                                      36
<PAGE>   37

    the control of separate, not necessarily compatible, network control
    systems. The HER network's uniform technology enhances service by providing
    quality and reliability as well as uniformity of features throughout the
    network.

        Diverse Routing. The HER network architecture includes diverse,
    redundant routes that are designed to provide high levels of reliability.
    The network is designed to provide availability of over 99.98% for most
    routes and to provide customers with a wide range of telecommunications
    transmission capacity. To achieve this level of reliability without the use
    of a network similar to the HER network, HER believes that carrier
    customers would need to purchase additional dedicated circuits to provide
    for redundancy.

        Rapid Provisioning. HER services provide access to the network, such
    that additional capacity can be provided to customers on the HER network on
    a rapid basis. This access provides a level of capabilities that HER
    believes is unavailable in Europe today. This ability to rapidly provide
    service is largely due to HER's development of capacity substantially in
    excess of HER's forecasted requirements.

    o   Flexibility. HER services are focused on providing customers
        flexibility across the network through which the customer may minimize
        risk by enabling network rerouting, eventually even under customer
        direct control.

    o   Advanced Technology. HER is deploying SDH technology which, by using
        WDM techniques and hardware, is upgradeable and will permit significant
        expansion of transmission capacity without increasing the number of
        fiber pairs in the network. This technology also provides the basis for
        structuring advanced operating features, such as virtual private
        network service and ATM-based services. Additionally, the SDH
        technology deployed by HER may be upgraded.

    o   Innovative Pricing. Currently the price of high-bandwidth E1 equivalent
        circuits on transborder European routes is artificially high and not
        necessarily related to the cost of such circuits. HER offers
        competitive pricing. HER also offers highly tailored contract terms and
        volume discounts, which allow carrier customers to plan more
        efficiently the fixed costs of their service portfolio. Customers can
        select varying capacity, access, guaranteed availability and contract
        terms at competitive prices. Customers sourcing from PTOs are generally
        limited to order from a very narrow set of capabilities offered under
        inflexible pricing plans.

    Although HER and GTS have relationships with certain PTOs or other access
providers for specific projects, they do not have wide-ranging alliances with
any of the major consortia or large Western telecommunications companies.
Additionally, HER's strategy calls for it to focus on carriers' carrier
services, so that it will limit overlap of target markets with its carrier
customers in end user markets. HER believes that this independence will make it
an attractive service provider for carriers who may otherwise be reluctant to
obtain services from other providers of intra-European transport that also may
be their competitors in the retail market.

SERVICES

    HER's primary service is large capacity cross-border European circuits
provided to carriers and service providers over an integrated, managed
pan-European network structure thus providing a service for wholesale customers
such as PTOs and New Entrants. The HER network will be based on SDH technology,
which provides for digital transmission capability upon which a broad range of
advanced functionality may be built and which offers network availability,
flexibility, bandwidth speeds and error performance not otherwise available to
carriers for transport of telecommunications traffic across national borders in
Western and Central Europe. The network is designed to provide customers with a
wide variety of bandwidth speeds, ranging from VC12/E1 Standard (equivalent to
2.048 Mbps) to STM-1/E4 Standard (equivalent to 155 Mbps) and beyond.

    HER will provide high quality cross-border transmission services for
licensed or otherwise authorized telecommunications providers. Services are
based on the principle of adding greater value than currently available in the
market while retaining competitive prices.



                                      37
<PAGE>   38

    Point-to-Point Transport Service. The current market for cross-border
transport is served by IPLCs provided by PTOs. IPLCs are formed by combining
half-circuits from two PTOs between customer locations, often with additional
PTOs providing transit segments. Under the IPLC service, overall service
quality guarantees generally are not provided and only a limited range of
bandwidth is available, usually only E1 and in certain instances, E3. The
Company believes that HER's Point-to-Point Transport Service will be a major
improvement to the PTO-based approach because it provides a greater range of
bandwidths (from 2 Mbps (E1 or VC-12) to 140/155 Mbps (E4 or VC-4)) and allows
customers to choose a service level agreement with guarantees appropriate for
their applications, including guarantees for on-time service delivery and
service availability.

    Point-to-Point Transport Service consists of two services, "Integrated" and
"Node-to-Node." The HER "Integrated" service provides an end-to-end service
between customer-specified locations where the customer can request for HER to
arrange for "last mile" services from the HER node location to the customer's
location. The HER "Node-to-Node" service can be selected when the customer
prefers to provide its own services to reach the local HER node location. In
Node-to-Node Service, HER guarantees service only on its portion of the network
between HER nodes. Both services are competitively priced relative to current
service offerings. A premium is charged for the highest guaranteed level of
service which incorporates an end-to-end, fully diverse, protected,
"Integrated" service. The customer can choose flexible contract terms from one
to five or more years' duration, with volume discount schemes designed to
ensure that HER remains a cost-effective solution.

    Virtual Infrastructure Service. Carriers and operators that plan to expand
their operations to become pan-European service providers as the European
marketplace is liberalized require a flexible and cost-effective means of
telecommunications transport. To date such service providers obtain
international transport service by leasing IPLCs. Leasing IPLCs requires a
carrier to lease channels on a segment-by-segment basis from multiple PTOs,
linking the target cities under arrangements having fixed capacity and pricing
structure for each segment of the carrier's network. Leasing IPLCs has several
disadvantages, including (i) difficulty in obtaining discount/volume pricing
schemes since there is no single provider of pan-European coverage, (ii) delays
in implementation due to numerous contractual negotiations and having to
interconnect numerous IPLCs, (iii) limited availability of pan-European leased
capacity at high bandwidth and (iv) variability of quality due to multiple
operators and the absence of a single uniform network. Operators could also
construct their own network, which is expensive, time-consuming and complex and
which may not be justified by such operators' traffic volume.

    HER's Virtual Infrastructure Service will offer a new solution and an
attractive alternative to leasing IPLCs or building infrastructure. This
service will enable HER's customers to obtain a uniform pan-European or
cross-border network under one service agreement by allowing the customer to
select any number of cities along the HER network at a pricing structure based
on the overall amount of leased capacity for the customer's entire network. The
key feature behind Virtual Infrastructure Service is that it gives the customer
the ability to add or reconfigure capacity in 24 hours between locations
connected in the Virtual Infrastructure Service, thereby enabling the customers
to respond almost immediately to changes in traffic. By being able to transfer
capacity among the network routes, HER's customers are able to avoid over- and
under-utilization of leased channels. This service offering provides a customer
with the benefits of ownership (rapid provisioning, freedom to rearrange and
control) with a "pay-as-you-go" managed service offering, without the burdens
of up-front investment and costs required to build a network, and without
having to manage the on-going maintenance and operation of the network.

    The service would be delivered through pre-installed physical facilities at
each of the customer locations. These facilities are designed to ensure that
most growth or changes in customer requirements can be addressed purely by
remote logical reconfiguration from the HER Network Operations Center. This
remote network management ability is inherent in SDH technology and allows
rapid provisioning and high quality of service.

    Ring Service. Most medium to large carriers and operators purchase network
capacity in excess of actual requirements, and prefer to have physical
configuration control over their networks. The HER Ring Service connects
multiple customer locations with multiple VC-4 paths in a ring configuration.
The customer has direct control over the configuration of the VC-3 and VC-12
paths within the ring, and has exclusive control over the routing. Additional
ring capacity can be added with no service interruption and additional customer
locations may be added to the ring with minimal service interruption. Because
HER is not required to configure 'idle' bandwidth or


                                      38

<PAGE>   39
to manage the 'SDH subnet' this service can be provided at a very competitive
rate vis-a-vis other point-to-point services.

    Sales and marketing of HER's services are conducted through its sales and
marketing department, which includes a director and senior sales managers
responsible for various regions and customer segments. Additionally, HER
expects that certain of its railway shareholders and/or railway or other
infrastructure providers that develop domestic telecommunications businesses,
or other local network access providers, can provide an effective distribution
channel to smaller carrier customers.

PRICING

    Currently the price of cross-border pan-European calls are often
significantly higher than the underlying cost of transport 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 HER
to attractively and competitively price services in the face of declining
overall tariffs for telecommunication services. HER's low-cost basis is due to,
among other things, its use of up-to-date technology without the burden of
legacy networks, which requires fewer employees to operate.

    The term of a typical customer agreement currently ranges from 1 to 3
years. The customer agrees to purchase, and HER agrees to provide, cross-border
transmission services. In general the customer agrees to pay certain
non-recurring charges upfront and recurring charges on an annual basis, payable
in twelve monthly installments. If the customer terminates the service order
prior to the end of the contract term, it is generally required to pay HER a
cancellation charge equal to three months service for each of the twelve months
remaining in the contract term. HER guarantees transmission services to a
certain service level. If such levels are not met or HER fails 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.

CUSTOMERS

    HER's high capacity, SDH-based fiber optic network is designed to enable
PTOs and New Entrants to integrate high quality, cross-border capacity into
their end user offerings. As of January 1998, twenty customers were under
contract for service on the HER network, including PTOs, a global consortium of
PTOs, Internet service providers, an international carrier, value added networks
("VANs") and resellers. HER provided capacity of approximately 446 E1 equivalent
circuits as of January 1998. The type and quality of HER's customers validates
the concept of the HER network, and illustrates the type of customers who will
be attracted to the full network. The success of this limited network also
demonstrates the demand for cross-border transport services. In total, HER is
targeting seven major market segments or customer groups which can be
characterized as follows:

    o   Existing PTOs. This customer segment consists of the traditional
        European PTOs that generally participate in the standard bilateral
        agreements for cross-border connectivity. Hermes provides a vehicle for
        PTOs to compete in non-domestic markets both before and after January
        1, 1998. As of January 1, 1998, both reserved and non-reserved traffic
        can be transported by alternative infrastructure providers, thus vastly
        expanding the available PTO market for HER.

    o   Global Consortia of Telecommunications Operators. Many of the largest
        PTOs and international carriers have pooled resources and formed
        consortia in order to compete more effectively in important
        telecommunications markets such as those in Western Europe particularly
        outside their home markets. Prior to liberalization of the provision of
        switched voice services in Western European markets, one of the primary
        objectives of these consortia is to provide non-reserved pan- European
        services to multinational business customers, including X.25/frame
        relay (high speed data network) service and closed-user group voice
        services. Under the current regulatory framework, consortia would
        otherwise be required to purchase leased lines at negotiated retail
        rates, even within their home countries. HER believes that it provides
        an attractive alternative at better pricing in those environments where
        such a consortium does not already own its



                                      39
<PAGE>   40

        infrastructure. Furthermore, HER believes that it is well positioned to
        provide cross-border connectivity between different domestic
        infrastructures of these alliances.

    o   International Carriers. This customer segment consists of non-European
        carriers with traffic between European and other international
        gateways. Such carriers include Teleglobe, GTS-Monaco Access and
        eventually the U.S. Regional Bell Operating Companies. HER can provide
        these customers a pan-European distribution network to gather and
        deliver traffic to and from their own and other hubs.

    o   Alternative Carriers. This segment consists of second carriers, cable
        TV and mobile carriers and competitive access providers. These new
        carriers have chosen to compete with the incumbent PTOs in their
        respective countries, and the Company believes that they would look
        favorably to an alternative such as HER. HER believes that this segment
        will sustain the largest growth as competition emerges in Europe. HER
        also believes that non-PTO competitors in Europe will prefer to use a
        non-PTO alternative like HER to meet their cross-border
        telecommunication transport needs.

    o   Internet Backbone Networks. Internet backbone networks are a fast
        emerging segment and are expected to generate significant requirements
        for the services HER offers. These require large capacity international
        connectivity services between Internet nodes (point of interconnection
        between local Internet service providers) in all local European
        markets. The Internet segment is experiencing significant growth in
        demand for transmission capacity.

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

    o   VANs and other Service Providers. VANs are data communications systems
        in which special service features 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. VANs' basic
        network transmission requirement is to connect data switches or
        processors. VANs currently purchase their own international circuits
        and build additional resiliency into their network infrastructure. HER
        will allow them to meet these needs cost-effectively, and to extend
        their services to new markets or customers without substantial capital
        investment.

    HER expects that additional demand for alternative service providers will
come from increased usage of dedicated circuits for Internet access, private
lines for the deployment of wide-area networks by large corporations, "single
source" local and long distance services by small and medium-sized businesses
and emerging broad band applications such as cable TV programming distribution
(other than broadcast) to the end user.


NETWORK DESIGN

    Network Architecture. The network architecture is based on a highly meshed
flat topology which covers a wide geographical area with large distances
between individual network nodes. This architecture allows rerouting of traffic
at electronic speeds in the event of a network failure. This approach also
lowers network cost by allowing each node to be sized to match anticipated
traffic volumes rather than to a standard capacity. Individual nodes can be
configured to connect any trunk to any other in the nodes, thus allowing
efficient transmission of traffic. Each node will be connected to at least two
other nodes allowing rerouting of traffic in the event of a network failure.
HER believes that its network will be the first cross border pan-European
network with such redundancy.

    The HER network has been designed to be controlled by a single network
management center and supported by advanced operational support systems. A
centralized network center can pinpoint overloaded pathways or malfunctioning
circuitry and reroute traffic much more quickly than networks controlled by
separate network centers operated by PTOs in different countries. HER primarily
uses Alcatel for the supply of transmission



                                      40
<PAGE>   41

equipment and network management systems. HER's advanced operational support
systems allow it to correct network failures and isolate equipment faults with
greater speed and at a lower cost than is the case with heterogeneous
multi-operator networks. Critical elements of the network, including network
maintenance and control systems, are designed with redundancy in order to
ensure a high quality of service. The network design has several important
resilience features including: multiple paths to each node, built-in hardware
redundancy and redundant power supplies. For all network routings, there will
be at least two paths. Should service failure occur on one route, the network
is designed to automatically re-route traffic to another route. HER believes
that these techniques will result in performance of 99.98 percent or better for
premium service customers for most routes.

    HER expects to operate the entire network and to own substantially all of
the 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 HER because they reduce the capital expense
burden of building large quantities of capacity before they can be used. Where
HER leases dark fiber, the infrastructure provider will generally be
responsible for maintaining such fiber optic cable. HER will enter into
agreements with Alcatel and infrastructure providers and other third parties to
supply and/or maintain the equipment for the HER network.

    Network Capacity. The network will consist of Synchronous Digital Hierarchy
("SDH") STM-16 links managed by equipment and operating centers owned by HER
and running on dark fiber leased from infrastructure providers or built by HER
on leased rights of way. Each line system and multiplexer works initially at
the 2.5 Gbps (STM-16) level. The most important types of equipment used or to
be used in this network are Add-Drop Multiplexors ("ADMs") and regenerators and
a variety of optical amplifiers for boosting optical signals. The STM-16 links
are expected, where needed, to be upgraded to STM-64. Furthermore, fibers will
be multiplexed using WDM, also as required. Additional capacity can be achieved
by adding new fiber accesses to a given city over alternative routes, thereby
achieving more meshing and the resulting improved network availability.

    Network Agreements. HER has entered into agreements and letters of intent
with various infrastructure providers for construction and/or dark fiber lease
of portions of the HER network. HER's agreements for leases of portions of the
network typically required the infrastructure provider to provide a certain
number of pairs of dark fiber and node and/or regenerator sites along the
network route commencing on certain dates provided by HER. The term of a lease
agreement typically ranges from 10 to 18 years. An agreement typically contains
optical specification standards for the fiber and methods of testing. HER is
allowed to use the cable for the transmission of messages and in other ways,
including increasing capacity. The infrastructure provider also provides space
for the location of equipment and spare parts and guarantees the provision of
power and other utilities together with environmental controls and security to
ensure the proper functioning of the equipment. The infrastructure provider is
typically responsible for maintenance of the cable and the provision of first
line maintenance to equipment and permits HER access to such facilities. Access
arrangements to the nodes are also provided so that connection may be made to
HER customers or to the rest of the network. An agreement also provides for an
annual price for the provision of fiber and for the facilities and maintenance.
The agreements typically provide for termination by the parties only for
material breach, with a 90 day minimum cure period. The agreements typically
contain a transition period after termination of the agreement to allow HER to
continue to serve its customers until it can reach agreement with an
alternative infrastructure provider.

    Local Access. Access to the HER network will be provided to clients through
SDH access lines including at the STM-1 or STM-4 level. However, customers who
continue to use the older PDH technology may also access the HER network. In
each city, as a HER point of presence is deployed, HER may contract with a
local access network supplier for "last mile" services to customer locations.
HER will not invest in building local access infrastructure but such
connectivity can be supplied on a case-by-case basis via preferred local access
partner arrangements. Currently Telfort in the Netherlands and Belgacom in
Belgium are providing local access to the operating Amsterdam-Brussels route.
In London and Paris, HER has contracted with local access providers to connect
the HER network to intra-city networks in those cities. Pursuant to this
agreement, HER can offer its carrier customers local connectivity in those
cities. Various Local Access Network Suppliers may also be interested in HER
for the purpose of linking the business centers in which they are active.
Therefore, the Company believes that the relationships between HER and local
access network suppliers can benefit both parties.



                                      41
<PAGE>   42

    Network Routes. HER's current planning dates for operation in certain
cities and kilometers covered by the initial network in the first five
countries and Switzerland are set forth below . 

Expected to be operational by:

April 30, 1998 - Brussels, Antwerp, Rotterdam, Amsterdam, London, Paris,
Strasbourg, Frankfurt, Zurich and Geneva - covering approximately
3,000 kilometers.

June 30, 1998 - Above cities and Dusseldorf, Stuttgart and Munich - covering
approximately 3,800 kilometers.

    HER expects to have an aggregate of approximately 10,000 kilometers
completed at the end of 1998 and the entire 18,000 kilometer network completed
by the year 2000. Hermes also plans to lease capacity on a transatlantic cable
linking the European network with North America in 1999.

    The routes planned to be operational in the second quarter of 1998 are
currently under construction. "Under construction" means that with respect to
each of the segments that make up each of these routes, one of the following is
occurring: (i) HER has contracted to build or is contracting to build the fiber
optic cable segment, and (ii) HER has leased or will lease such segment of dark
fiber optic cable from a third party who has built or is currently building
such segment. The dates set forth above may be subject to delays due to a
variety of factors, many of which are beyond the control of the Company.

    HER is deploying the network along the rights-of-way of a variety of
alternative sources, including railways, motorways, waterways, pipelines and
utilities. The rights-of-way of HER-built portions of the network will be
provided pursuant to long-term leases or other arrangements entered into with
railways, highway commissions, pipeline owners, utilities or others. It is the
policy of HER to evaluate multiple alternative infrastructure suppliers in
order to maximize flexibility. As a result of its network development
activities to date, HER has gained access to infrastructure for its network
routes which, in certain cases, HER believes will be difficult for its
competitors to duplicate.

Competition

    The European and international telecommunications industries are
competitive. HER's success depends upon its ability to compete with a variety
of other telecommunications providers offering or seeking to offer cross-border
services, including (i) the respective PTO in each country in which HER
operates and (ii) global alliances among some of the world's largest
telecommunications carriers. HER expects that some of these potential
competitors may also become its customers. HER believes that the ongoing
liberalization of the European telecommunications market will attract New
Entrants to the market and increase the intensity of competition. Competitors
in the market compete primarily on the basis of price and quality. HER intends
to focus on these factors and on service innovation as well. HER business plan
anticipates substantial head-to-head competition as well as indirect
competition.

    WorldCom, Inc. ("WorldCom") recently announced plans to construct a
pan-European fiber network, the first phase of which is expected to connect
London, Amsterdam, Frankfurt, Brussels and Paris by early 1998. Although the
Company believes that the proposed WorldCom pan-European network is primarily
intended to carry WorldCom traffic, WorldCom has stated that any excess
capacity on such network will be used to provide a competitive carrier's
carrier service.

    Viatel, Inc. ("Viatel") also recently announced its intention to build a
pan-European fiber optic network connecting select cities in Belgium, France,
the Netherlands and the United Kingdom. Excess capacity would be available for
other carriers. Viatel has stated that, assuming that it obtains necessary
financing, construction would begin in spring 1998 and the network would become
operational in 1999.



                                      42
<PAGE>   43

    In addition, Exprit Telecom Group plc ("Esprit") also recently announced
plans to construct an SDH fiber optic ring network that will connect the United
Kingdom, France, the Netherlands and Belgium.

    HER also competes with respect to its "point-to-point" transborder service
offering against circuits currently provided by PTOs through International
Private Leased Circuits. In addition, the liberalization of the European
telecommunications market is likely to attract additional entrants to both the
"point-to-point" and other telecommunications markets.

    If HER's competitors, many of whom possess greater technical, financial and
other resources than HER, devote significant resources to the provision of
pan-European, cross-border telecommunications transport services to carriers,
such action could have a material adverse effect on HER's business, financial
condition and results of operations. There can be no assurance that HER will be
able to compete successfully against such new or existing competitors. See
"--Certain Considerations Generally Applicable to the Company's Operations -
Competition."

HER RECAPITALIZATION

    During 1997, HER completed a recapitalization (the "HER Recapitalization"),
wherein HER extended rights to subscribe to additional shares of HER to
GTS-Hermes, HIT Rail and the eleven railways comprising the HIT Rail
consortium. Pursuant thereto, GTS-Hermes and two of the eleven railways that
comprise the HIT Rail consortium have exercised their subscription rights,
while HIT Rail and the other nine railways have declined to exercise their
subscription rights. HER has issued (i) 150,592 shares to GTS-Hermes in
exchange for the conversion of loans and additional consideration, (ii) 24,007
shares to HIT Rail in exchange for the conversion of loans, (iii) 11,424 shares
to Societe Nationale des Chemins de Fer Belges S.A. de Droit Public/Nationale
Maatschappij der Belgische Spoorwegen N.V. Van Publiek Recht (the Belgian
national railway) ("SNCB/NMBS") and (iv) 4,365 shares to AB Swed Carrier (a
wholly owned subsidiary of SJ, the Swedish national railway). As a result,
GTS-Hermes owns 79.1%, HIT Rail owns approximately 12.6%, SNCB/NMBS owns 6.0%
and AB Swed Carrier owns 2.3% of the issued HER shares. Pursuant to the HER
Recapitalization, HER, GTS-Hermes, HIT Rail, SNCB/NMBS and AB Swed Carrier have
executed a new Shareholders Agreement, the principal terms of which are set
forth below. In March 1998, Hit Rail sold all of its shares in HER to
GTS-Hermes, SNCB/NMBS and AB Swed Carrier. As a result of such sale,
GTS-Hermes, SNCB/NMBS and AB Swed Carrier currently own 170,307, 13,610, and
6,551 shares of HER, repectively, or 89.4%, 7.2%, and 3.4%, respectively of
HER.

    Under the new Shareholders Agreement, actions to be taken by shareholders
will be adopted by a simple majority vote with the exception of certain actions
which will require at least 85% of the votes cast: (i) purchase by HER of its
own shares and any redemption thereof, (ii) exclusion of preemptive rights in
the case of the issuance of new shares and the transfer of shares held by HER,
except in the event of a public listing of the shares or of new shares or of an
offering of shares or options on new shares (warrants) to professional
investors in order to obtain further funding, (iii) winding up or dissolution
of HER, (iv) any amendment to the articles of association other than those
pertaining to increases in the authorized capital of HER or to convert HER into
an N.V. ("Naamloze Vennootschap") to enable a public listing of shares or new
shares, (v) any amendment to the scope of HER's business, (vi) the declaration
of dividends and (vii) the admission of new shareholders to the Shareholders
Agreement. In addition, the Shareholders Agreement provides that (a) if
GTS-Hermes is the owner of at least 50% of the issued shares, then it will have
the right to make a binding nomination for the appointment of half of the
members of the Board of Supervisory Directors or (b) if GTS-Hermes is the owner
of at least two-thirds of the issued shares, then it will have the right to
make a binding nomination for the appointment of half of the members of the
Board of Supervisory Directors plus one member more, appointed pursuant to
nominations by all other shareholders. As long as HIT Rail is the owner of at
least one share, HIT Rail will be entitled to make a binding nomination for the
appointment of at least one member of the Supervisory Board. The Shareholders
Agreement also provides that shareholders who participated in the capital
restructuring other than GTS-Hermes and HIT Rail with a shareholding of at
least 6.8% subject to adjustment in the discretion of the other shareholders
will be entitled to make a binding nomination for the appointment of one member
of the Board of Supervisory Directors. Shareholders who participated in the
capital restructuring other than GTS-Hermes and HIT Rail who hold fewer than
6.8% of the issued share capital of HER will be entitled on a rotating basis to
make one binding nomination for the appointment of a member of the Board of
Supervisory Directors for two-year periods. As a result of the March 1998 sale
by Hit


                                      43
<PAGE>   44

Rail of all its shares in HER, Hit Rail no longer has any rights or
obligations, except as set forth below, under the Shareholders Agreement and
GTS-Hermes, acting alone, can approve all the matters described above which
require an 85% HER shareholder vote.

Articles of Association and Shareholders Agreement

    Under the Articles of Association and the Shareholders Agreement, HER's
shareholders have preemptive rights in connection with issuances of ordinary
shares and options on shares to be issued in proportion to the total nominal
value of the shares held by it. Preemptive rights can be exercised for four
weeks after the date the notice of the offer is received by the shareholders.

    The Shareholders Agreement provides that HER or its designated vendor will
provide fiber capacity in its network for use by the shareholders of HER on
fair commercial terms, use, quantity and price to be negotiated on a bilateral
basis. In the Shareholders Agreement, HIT Rail has covenanted to (i) use its
best efforts to establish such commercial agreements between individual HIT
Rail shareholders and HER, to obtain rights of way from individual HIT Rail
shareholders and to cooperate in obtaining such licenses as may advance the
business of HER, (ii) use its best efforts to ensure that the HIT Rail
shareholders cooperate in obtaining such license in accordance with the
business plan of HER and as may be necessary or advisable in furtherance of
HER's business, (iii) will not, so long as both HIT Rail and GTS-Hermes are
shareholders of HER and for one year after HIT Rail ceases to be a shareholder,
agree with any entity other than GTS-Hermes or HER to assist or cooperate in
the development of any pan-European telecommunications operator and (iv) use
its best efforts to obtain on HER's behalf such materials as may be required
and arrange inspection visits of selected rights of way for the purpose of
making initial cost estimates.

    The foregoing summary of the Shareholders Agreement does not purport to be
complete and is qualified in its entirety by reference to the Shareholders
Agreement, which is an Exhibit to this Report.

LICENSES AND REGULATORY ISSUES

    A summary discussion of the regulatory framework in the countries of the
network in the first five countries and the next five countries into which HER
expects to develop the 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.

    National authorities in individual member states of the EU are responsible
for regulating the operation (and in some cases the construction) of
telecommunications infrastructure. HER believes that the adoption of the Full
Competition Directive and the various related Directives adopted by the
European Parliament and the Council of the EU have resulted in the removal of
most regulatory barriers to the operation of telecommunications infrastructure
in the countries of the initial network in the first five countries.

    HER requires licenses, authorizations or registrations in all countries to
operate the network. There can be no assurance that HER will be able to obtain
such licenses, authorizations or registrations or that HER's operations will
not become subject to other regulatory, authorization or registration
requirements in the countries in which it plans to operate. Licenses,
authorizations or registrations have been obtained in the United Kingdom, the
Netherlands, Belgium, France and Germany and a trial concession has been
granted in Switzerland. HER intends to file applications in other countries in
anticipation of service launch in accordance with the network roll-out plan.

    On June 28, 1990, the European Commission, in an effort to promote
competition and efficiency in the European Union, issued a directive (the "1990
Directive") requiring EU member states to immediately liberalize all
telecommunication services with the exception of voice telephony to the general
public (basic voice services provided over the public switched voice network).
This step liberalized value added services and voice services over corporate
networks and/or "closed user groups," although the exact definitions of the
terms used in the 1990 Directive were not altogether clear.


                                      44
<PAGE>   45


    On July 22, 1993, the Council of EU agreed that all voice telephony
services in EU member states should be liberalized by January 1, 1998 subject
to additional transitional periods of up to five years to allow member states
with less developed networks to achieve the necessary adjustments. It was
agreed that such exemptions would be granted to Spain, Ireland, Greece and
Portugal, subject to formal application and satisfaction of certain
requirements. Luxembourg, because of the small size of its market, would be
eligible for a special transitional period of up to two years.

    In April 1995, a communication from the European Commission sought to
clarify the types of services that were liberalized by the 1990 Directive,
stating that the burden of proof as to why a service should be considered
"reserved" and therefore not open to competition should be upon the PTOs and
the regulatory authorities of member states. Along with this statement came the
threat of formal procedures under the Treaty of Rome against member states that
do not implement the 1990 Directive "within a reasonable time." Procedures have
been brought so far against Italy, Greece, Germany and Spain for failing to
apply the requirements of the 1990 Directive.

    On March 13, 1996, the European Commission adopted the Full Competition
Directive extending the 1990 Directive to all services, requiring that
licensing procedures for these services be transparent and non-discriminatory,
requiring member states to fully liberalize alternative infrastructure to allow
a competitive market for "non-reserved" services such as data, value added
services and non-public (closed-user group) switched voice services by July 1,
1996 and mandating open competition in all public telecommunications services,
including voice telephony to the general public, by January 1, 1998 (except for
countries to which grace periods were granted in accordance with the 1993
Council Resolution).

    On April 10, 1997, the European Parliament and the Council of Ministers
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 will be required to be dealt with in a
timely fashion. The number of licenses may only be restricted to the extent
required to ensure the efficient use of radio frequencies or for the time
necessary to make available sufficient numbers in accordance with EC law.

    HER believes that many European countries have revised telecommunications
regulations to comply with the 1990 Directive and the Full Competition
Directive and that such changes will enhance HER's ability to obtain other
necessary regulatory approvals for its operations.

    As a multinational telecommunications company, HER is subject to varying
degrees of regulation in each of the jurisdictions in which it provides its
services. Local laws and regulations and the interpretation of such laws and
regulations, differ significantly among the jurisdictions in which HER
operates. There can be no assurance that future regulatory, judicial and
legislative changes will not have a material adverse effect on HER, that
domestic or international regulators or third parties will not raise material
issues with regard to HER's compliance or noncompliance with applicable
regulations or that regulatory activities will not have a material adverse
effect on HER. See -- "Certain Considerations Generally Applicable to the
Company's Operations -- Government Regulation." The regulatory framework in
certain jurisdictions in which HER provides its services is briefly described
below.

United Kingdom

    Since the elimination in 1991 of the United Kingdom telecommunications
duopoly consisting of British Telecommunications and Mercury, it has been the
stated goal of Oftel, the United Kingdom telecommunications regulatory
authority, 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.
HER has received a license from the Secretary of State for Trade and Industry
which grants it the right to run a telecommunications system or systems in the
United Kingdom connected to an overseas telecommunications system and to
provide international services over such systems. Like the licenses granted to
other providers of international facilities-based services, the license granted
to HER on December 18, 1996 was for an initial six months' duration and
thereafter is


                                      45

subject to revocation on one month's notice in writing. The short duration of
these initial licenses was adopted for administrative convenience on the
opening-up of the United Kingdom market for international facilities-based
services. The Department of Trade and Industry ("DTI") has confirmed that it
intends to replace the initial licenses with new licenses and that it would not
normally expect to revoke an initial license without replacing it with another
license giving an equivalent authorization. The DTI is currently discussing
with license holders the arrangements to put these new licenses into effect and
although the DTI has indicated that the new licenses are expected to be of 25
years duration, there can be no certainty that this will be the case or that
the new licenses will not contain terms or conditions unfavorable to HER.

The Netherlands

    On July 1, 1997 the Dutch government abolished the prohibition on the use
of fixed infrastructure for the provision of public voice telephony, thereby
complying with the requirements of the Full Competition Directive six months
ahead of schedule. On August 1, 1996, HER was granted a license for the
installation, maintenance and use of a fixed telecommunications infrastructure.

    An entirely new Telecommunications Bill was introduced to the Second
Chamber (the House of Representatives) of the Parliament on September 15, 1997.
The new Telecommunications Act is intended to confirm the full liberalization
of the telecommunications market according to European Community standards. It
is not expected that the new Telecommunications Act will detrimentally affect
the conduct of business by HER.

Belgium

    Belgium has implemented the "alternative infrastructure" provider provision
of the Full Competition Directive. The decision-making process regarding the
adoption of the full package of liberalization legislation (including licensing
regimes for voice telephony and public network infrastructure) is in the final
stages and is anticipated to be completed by mid - 1998.] Given the fact that
the implementation of the EC Directives is late, the Belgian authorities have
made public that they will work during the first months of 1998 with a system
of provisional licenses. HER has obtained, through a wholly-owned subsidiary, a
license from the Belgian regulatory authority to provide liberalized services
using alternative infrastructure and is currently operating under its license
in Belgium on the Brussels-Amsterdam route. HER also has authorization to build
infrastructure between major Belgian population centers and the relevant border
crossings. The liberalization legislation is expected to require all previously
licensed operators to apply for new licenses or authorizations. HER expects
that, in such event, its existing licenses and authorizations would be renewed
in due course, although there can be no assurance that this will be the case.

Germany

    Germany has approved legislation to implement the Full Competition
Directive and remove all remaining restrictions on competition from January
1998. HER was granted a license by the German regulatory authorities on July
18, 1997. The license permits HER to operate the portions of the network in
Germany connecting Dusseldorf, Frankfurt and Stuttgart; Dusseldorf to the Dutch
border; and Stuttgart to the French and Swiss borders. HER expects to extend
its license in Germany as appropriate in order to enable it to operate the
remaining portions of the network in Germany.

France

    A new regulatory agency, the Autorite de Regulation des Telecommunications
("ART"), was established in France effective January 1, 1997. In 1996, France
approved legislation to implement the Full Competition Directive and to remove
all remaining restrictions on competition from January 1998. HER applied for an
authorization to operate its network in specific regions of France, which was
approved on October 22, 1997. In October 1997, HER obtained authorization to
operate its network in specific regions of France. Such authorization requires
prior notification to and approval of the ART of any substantial changes in the
capital of HER or its controlling 


                                      46
<PAGE>   47

shareholder. HER has notified the ART of the initial public offering of the
Company's common stock and intends to notify the ART of the March 1998 increase
to approximately 89% of GTS-Hermes, ownership interest in HER.

Switzerland

    The Swiss Parliament has recently passed a new Telecommunications Law which
will enter into force on January 1, 1998. Although Switzerland is not a Member
State of the EU, the effect of the law is largely to mirror the EC
telecommunications liberalization Directives and therefore from that date
existing voice telephony monopoly will be abolished and such services will be
fully liberalized. An independent national regulatory authority has previously
been established. HER obtained a trial concession on October 30, 1997, in order
to roll out its network and to provide its services in advance of the full
liberalization coming into effect on January 1, 1998. This concession expired
on December 31, 1997. HER has filed an application for a concession for the
operation of a telecommunications infrastructure and was granted a provisional
concession on March 16, 1998. The provisional concession takes retroactive
effect as of January 1, 1998 and HER expects that the Swiss regulatory
authority will grant HER a final concession by the end of the third quarter
1998. However, no assurance can be given that such final concession will be
granted or granted on terms acceptable to HER.

Italy

    Although in the past Italy has been dilatory in implementing EC
liberalization measures, Italy enacted legislation on July 31, 1997 which
substantially completes the liberalization of services in accordance with the
Full Competition Directive. The Parliament has also approved the creation of an
independent national regulatory authority for the telecommunications and
audiovisual sectors. The most recent EC liberalization Directives relating to
licensing and interconnection has been implemented. HER intends to apply for a
license to provide its services in due course.

Spain

    Under the Full Competition Directive Spain was granted the right to request
a delay of up to five years in liberalizing fully its telecommunications
market. However, the Spanish government and the European Commission have agreed
that full liberalization should take place on December 1, 1998. In order to
ensure effective liberalization from that date, the Commission Decision
granting the eleven month extension sets out a timetable of interim measures
leading up to full liberalization. These measures include the passing of
legislation authorizing regional cable operators to provide telecommunications
services and the adoption of a new General Telecommunications Bill effectively
transposing EC Directives into Spanish law. Further RETEVISION, S.A. has been
granted a second national operator's license to compete with the national PTO
and Spain has agreed to grant a third national operator license in early 1998.
HER intends to apply for a license to provide its services in due course.

Sweden

    Full liberalization of the Swedish telecommunications market occurred in
1993. A new Telecommunications Act was passed this year to reinforce the powers
of the national regulatory authority, to ensure conformity with EC Directives
and to supplement the pre-existing licensing regime with a general
authorization regime for services other than telephony services, mobile
services and leased lines. HER intends to register to provide its services in
due course.

Denmark

    With the liberalization of infrastructure from July 1, 1997 Denmark has
fully liberalized its telecommunications markets in accordance with the
requirements of the relevant EC Directives. An independent national regulatory
authority has been established. According to the Danish rules, HER will not
require any regulatory approval in order to install or operate the network in
Denmark.


                                      47
<PAGE>   48


    In addition, to the discussion above, HER intends to file applications in
other countries in anticipation of service launch in accordance with the HER
network roll-out plan. The terms and conditions of HER's licenses,
authorizations or registrations may limit or otherwise affect HER's scope of
operations. There can be no assurance that HER will be able to obtain, maintain
or renew licenses, authorizations or registrations to provide the services it
currently provides and plans to provide, that such licenses, authorizations or
registrations will be issued or renewed on terms or with fees that are
commercially viable, or that the licenses, authorizations or registrations
required in the future can be obtained by HER. 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 HER and the Company.

GTS-MONACO ACCESS

    GTS owns a 50% interest in and manages GTS-Monaco Access, a joint venture
with the Principality of Monaco created to develop Monaco's existing
international telecommunications infrastructure into an international gateway
hub for transport of international traffic to European and overseas
destinations. The Principality has constructed and operates a sophisticated
international gateway infrastructure that includes an international digital
switching center and a satellite earth station to support significant amounts
of carriers' carrier traffic. Through Monaco's network, GTS-Monaco Access is
linked to approximately 170 countries worldwide. GTS believes that this
partnership provides it with the opportunity to build a strong international
gateway operator in lucrative Western European markets.

    GTS-Monaco Access offers competitively priced international switching and
transit services, primarily to the "wholesale" international gateway and
carrier-to-carrier portion of the international calling market, as
distinguished from "retail" services offered to end users. Basic service
offerings include (i) international switched traffic; (ii) international
private lines; (iii) facilities management, including billing, customer
management and fault reduction systems; (iv) resale distribution for Internet
service providers; and (v) prepaid calling card platform services.

    With the cooperation of Monaco Telecom ("MT"), GTS-Monaco Access is
entitled to exercise the privileges of signatories to international treaties
such as the ITU, and to international satellite agreements, such as Intelsat,
Inmarsat and Eutelsat. Other signatories are generally PTOs and other
quasi-governmental telecommunications entities. GTS-Monaco Access purchases
capacity on international fiber routes at rates available only to recognized
operators which are substantially below the rates charged to other service
providers. These fiber-based facilities are an important element for GTS-Monaco
Access's core network and provide it with capacity that may be leased or resold
to customers. Monaco inaugurated its independent country code, 377, on June 21,
1996, which made it eligible for certain privileges, including special terms
(generally reserved for PTOs) in connection with transmission agreements,
transit agreements, settlements and low-cost accounting rates with select
carriers.

    GTS's partner in GTS-Monaco Access is an investment fund designated by the
Principality of Monaco to represent its interests. GTS-Monaco Access functions
in cooperation with MT under a commercial agreement governing, among other
things, the terms of use of existing facilities, access to and acquisition of
new international infrastructure, and sales and marketing. GTS exercises
operational control of the joint venture, and provides managerial and financial
support, international telecommunications expertise and strategic planning.
Neither GTS nor its partner is obligated to fund operations or capital
expenditures of GTS-Monaco Access. Losses and profits of GTS-Monaco Access are
allocated to the partners in accordance with their ownership percentages, in
consideration of funds at risk. As of December 31, 1997, GTS and its partner
had each made equity contributions of $0.8 million to GTS-Monaco Access. In
addition, GTS-Monaco Access had outstanding loans of $2.8 million to GTS as of
December 31, 1997. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Accounting Methodology -- Profit and
Loss Accounting." The agreement between GTS-Monaco Access and MT, by its terms,
continues in operation until 2020.

BUSINESS AND MARKETING STRATEGY

    GTS's strategy for developing GTS-Monaco Access into an international
gateway hub includes the following:


                                      48
<PAGE>   49


    o   Develop Advanced Carrier Services Offerings. GTS-Monaco Access may
        develop its "advanced carrier services" offerings to include global
        0800 services and international free phone services, which GTS believes
        will broaden customer relationships, enhance revenues and help to
        protect it from price-based competition.

    o   Develop Relationships to Broaden Service Offerings. GTS-Monaco Access
        may develop relationships to broaden its service offerings. GTS-Monaco
        Access has entered into agreements with UUNET, one of its gateway
        customers, to provide wholesale Internet access to GTS-Monaco Access's
        carrier customers in a number of Western European countries. The
        agreement allows these services to be "cobranded" with GTS's
        affiliates.

    o   Pricing. Price is a critical factor in the market for international
        switching as competition increases due to expanding international
        capacity, advances in technology and falling regulatory barriers.
        GTS-Monaco Access intends to price its services competitively with the
        prevailing price for comparable inter-PTO transit and gateway services.
        GTS-Monaco Access is not bound by legacy systems, infrastructure and
        personnel levels and can, therefore, manage competitive cost
        operations.

    o   Leverage Non-Aligned Position. Because GTS's Western European
        activities are not allied with any of the major consortia or large
        Western European telecommunications companies, and generally focus on
        carriers' carrier services, GTS-Monaco Access will not compete with its
        carrier customers in retail markets. This independence should make
        GTS-Monaco Access an attractive service provider for Western European
        carriers who may otherwise be reluctant to obtain services from the
        larger operators of international gateways that are often their
        competitors in the retail market.

    o   Exploit GTS Synergies. GTS-Monaco Access may ally with other GTS
        companies in Europe and the CIS. GTS-Monaco Access is expected to
        realize significant reductions in its cost structure through access to
        low-cost pan-European transmission capacity through alternative
        infrastructure providers such as HER, Sovintel and C-Datacom
        International, Inc., GTS's Indian venture, already route international
        traffic through GTS-Monaco Access's gateway.

CUSTOMERS

Targeted customers for GTS-Monaco Access include:

    o   Non-Aligned PTOs. GTS believes that various large American and Western
        European PTOs that lack adequate international switching and transport
        facilities of their own may be persuaded to purchase international
        services from GTS-Monaco Access, rather than from competing PTOs or
        consortia.

    o   Mobile Carriers. GTS believes that some of the non-PTO mobile carriers,
        which currently provide only a small percentage of Western European
        mobile telecommunications traffic, may prefer the "independent"
        international gateway service offerings of GTS-Monaco Access to those
        of their PTO competitors.

    o   Internet Service Providers. Growth in Internet usage creates a
        significant opportunity for a nonaligned Internet access provider such
        as GTS-Monaco Access, since many Internet service providers will be in
        direct competition with PTO-owned services in large European markets.

    o   Second Carriers/Resellers. GTS believes that many second carriers will
        seek to enter new markets quickly without investing in international
        switching capacity.

    o   Established ("Aligned") PTOs. This customer segment will be a niche
        market for GTS-Monaco Access. As markets are deregulated and carriers
        become increasingly competitive, traditional friendly correspondent
        relations may become strained, and opportunities may emerge to leverage
        GTS's non-aligned status to route traffic between rivals or to displace
        incumbents for transit relationships.


                                      49
<PAGE>   50



    o   Other GTS Companies. GTS-Monaco Access currently provides gateway
        services indirectly to Sovintel, CDI and other GTS companies that
        aggregate traffic or provide international long distance services. It
        may also provide these services to HER.

    In January 1998, GTS-Monaco Access terminated its relationship with a major
traffic partner as a result of which GTS expects that the venture will lose
approximately $6 million of revenues in 1998. Although GTS-Monaco Access is
putting in place plans to replace such revenues from other sources, no
assurance can be provided that such revenues will be replaced in the current
fiscal year.

NETWORK

    GTS has enhanced MT's existing technology platform of digital switching,
fiber optic transmission, satellite and submarine cable facilities by
interconnecting this existing network infrastructure to multiple terrestrial
routes covering Europe and to undersea fiber optic cables connecting the
GTS-Monaco Access network to Asia and the Americas.

    The network infrastructure of GTS-Monaco Access is complementary with that
of HER, with each serving the carriers' carrier market from different
perspectives; HER for bandwidth services and GTS-Monaco Access for switched
call terminations and other carrier services.

LICENSES AND REGULATORY ISSUES

    Because it operates in coordination with MT, the licensed operator of the
Monaco public network, and in indirect partnership with the government,
GTS-Monaco Access's telecommunications activities in Monaco require no
telecommunications license.

    Because the Principality of Monaco is not an EU member state, GTS-Monaco
Access's telecommunications activities in the Principality are not subject to
European law. However, GTS-Monaco Access will have to comply with EU regulation
to the extent it does business in EU member states. The regulatory requirements
established by the EU create general guidelines under which the national
agencies of EU member states regulate. Accordingly, local laws and regulations
may differ significantly among these jurisdictions, and the interpretation and
enforcement of such laws and regulations may vary. Local rules are sometimes
based on the informal views of the local ministries which, in some cases, are
subject to influence by the local PTOs. In certain of the Company's existing
and target markets, there are laws and regulations which affect the number and
types of customers which the Company can address. For instance, certain
countries may and do require licenses for communication companies to
interconnect to the public network to originate traffic.

    In addition, one of the services provided by GTS-Monaco Access is a form of
transit service, known in the industry as "re-filing." Re-filing is the
practice of routing traffic through a third country in order to take advantage
of disparities in settlement rates between different countries, allowing
traffic to a potential country to be treated as if it originated in the third
country that enjoys lower settlement rates with the destination country,
thereby resulting in lower overall costs on an end-to-end basis. Re-filing is
prevalent in the industry even though the practice is technically in
contravention of ITU regulations. In practice, because of the widespread
non-observance of these regulations, such a contravention normally does not
give rise to specific legal problems. However, their enforceability essentially
depends on the status given to ITU obligations by Member countries' domestic
laws. Accordingly, there can be no assurance that GTS-Monaco Access's re-filing
services might not be disrupted or be the subject of legal process at some time
in the future. In such event, within the EU a defense may be available that the
ITU regulations are anti-competitive and contravene the Treaty of Rome,
although there can be no certainty that such a defense would succeed.

COMPETITION

    GTS-Monaco Access faces competition from consortia of telecommunications
operators, large PTOs and other international telephone operators with advanced
network infrastructures, access to large quantities of long-haul

                                       50




<PAGE>   51

                                      
capacity and established customer bases. PTOs currently providing large amounts
of international traffic have already established direct routes, transit
arrangements and correspondent relations and many have excess capacity that
they resell in competition with GTS-Monaco Access.

    With the advent of deregulation in the Western European telecommunications
markets in 1998, opportunities for the establishment of international gateways
will likely develop in Europe and as a result competition in the market for
GTS-Monaco Access's services will increase. GTS intends to evaluate additional
locations in Europe for the establishment of international hubs based upon
prospective costs and the availability of call routing at these locations. GTS
plans to locate these prospective points of presence in cities served by HER
and to allow the termination of traffic through HER. GTS Monaco Access may
benefit from the establishment of these points of presence by incurring reduced
transmission expenses.

    While GTS believes that GTS-Monaco Access will be able to compete
effectively in certain identified market segments because most of its targeted
customers are in new and fast growing markets and have not established
long-term relationships with international gateway providers, and because it
has equal access to advanced infrastructure and international fiber routes,
potential access to low cost transport from HER and an "independent" status
that allows it to service a worldwide range of potential customers, GTS intends
continually to review the competitiveness of GTS-Monaco Access with respect to
its competitors.

CENTRAL EUROPE

    In Central Europe, GTS's objective is to become one of the leading
alternative telecommunications providers in the region. GTS currently provides
private data communications services to government and commercial customers in
Hungary and the Czech Republic. In the Czech Republic, the Company provides
outgoing voice services and operates an international gateway and a data
services network. In Hungary, GTS operates a VSAT network which GTS believes is
the largest VSAT network in Central Europe as measured by number of VSAT sites.
The Company has also signed an agreement to provide international data services
in Poland, subject to receipt of necessary governmental approvals. GTS's
strategy is to expand its service offerings as the regulatory environment
permits, leveraging its existing VSAT and international gateway infrastructure
where possible and providing a broad range of services to its target markets.

    Hungary

    GTS-Hungary. GTS-Hungary, a 99% owned subsidiary of GTS, is a leading
provider of customized data services offering high quality, reliable virtual
private network services to customers throughout Hungary and, through other GTS
affiliates, other countries in Central Europe. GTS-Hungary provides these
services through VSATs installed at customer sites throughout the country and a
microwave-based high speed overlay network for points in the Budapest
metropolitan area. Along with these data transmission services, GTS-Hungary
provides high quality customer service including (i) significant system
integration support in the initial implementation of the customers' networks
and in on-going expansion and improvements and (ii) a unique maintenance and
technical support service, which include "rapid response" service calls and
24-hour hub service operations support, which can be backed by financial
guarantees when required.

    As of December 31, 1997, GTS-Hungary's VSAT network consisted of
approximately 968 owned and operated VSAT sites which the Company believes
makes it the largest VSAT-based network in Central Europe. GTS believes that
its choice of VSAT technology as a way of quickly deploying a full range of
business services nationwide will allow it to capture key customers and market
segments. Such positioning, the Company believes, will enable GTS-Hungary to
expand its service offerings as the Central European market matures and as
regulatory authorities further privatize and deregulate the telecommunications
industry. GTS-Hungary is undertaking a nationwide expansion of its
microwave-based Budapest overlay network. The expansion will increase
GTS-Hungary's revenue base in the region and provide opportunities to leverage
further its other service offerings. There can be no assurance, however, that
the expansion will be completed on a timely and commercially feasible basis.


                                      51
<PAGE>   52


    The Hungarian state lottery is GTS-Hungary's largest customer, accounting
for more than 50% of GTS-Hungary's total revenue for the year ended December
31, 1997. GTS-Hungary has also targeted its VSAT network services to business
customers in the domestic service industry and other government organizations.
Although GTS-Hungary continues to diversify its revenue and customer base, the
loss of the Hungarian state lottery as a customer would have a material adverse
effect on GTS-Hungary's business.

    GTS-Hungary generally charges its data services customers a flat monthly
fee for a fixed amount of usage and usage-based fees for use above the
contractual amount. Customers are billed in Hungarian forints (indexed to U.S.
dollars) on a monthly basis. Pricing is generally determined for an individual
client based upon the size of traffic requirements. In general, GTS-Hungary's
strategy is to minimize the initial customer investment in order to lower the
barriers to purchase, while committing customers to long-term contracts.

    GTS-Hungary's major competitors include BankNet, Hungaro-DigiTel and MATAV,
the Hungarian PTO, each of which operates a network with at least 200 VSAT
sites. MATAV offers a broad range of services and has recently targeted the
business sector that GTS serves. GTS believes that, while some of its
competitors have stronger financial resources, GTS-Hungary remains the leading
VSAT service provider in Hungary in terms of number of VSAT sites, the size and
quality of its infrastructure and the quality of its service. GTS also believes
it has distinguished itself from its competition by its superior customer
service.

    Currently, all VSAT licenses in Hungary have been granted under temporary
telecommunications regulations. The temporary licenses prohibit connection to
public telecommunications networks or other international or domestic
data-transmitting systems. In December 1993, GTS received a temporary service
permit to provide data-transfer services utilizing a VSAT-based wireless
communications system throughout Hungary. In March 1997 the government issued
new telecommunications regulations which require all operations with temporary
licenses to apply for permanent licenses by the end of April 1997. GTS-Hungary
has submitted applications for the conversion of its temporary licenses to
permanent ones. While no assurances can be given, GTS expects permanent
licenses to be issued in due course. The failure to receive such licenses would
have a material adverse effect on the business of GTS-Hungary.

    Neither GTS nor its partner in GTS-Hungary are obligated to fund operations
or capital expenditures of GTS-Hungary. Losses and profits of GTS-Hungary are
allocated to the partners in accordance with their ownership percentages, in
consideration of funds at risk. As of December 31, 1997, GTS had made equity
contributions of $12.5 million to GTS-Hungary, GTS' partner has not made any
equity contributions as of December 31, 1997. In addition, GTS-Hungary had
outstanding loans of $2.8 million to GTS as of December 31, 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Accounting Methodology -- Profit and Loss Accounting." Further,
the joint venture does not have an expiration date.

    EuroHivo. In addition to its network and data services, GTS also provides
nationwide paging services primarily to the retail consumer market through its
70% owned joint venture, EuroHivo. GTS has concluded that EuroHivo is not a
core business and is currently assessing offers to sell its interests in
EuroHivo. In connection with this anticipated divestiture, the Company
wrote-off its investment in EuroHivo in the third quarter of 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations --Results of Operations -- Consolidated Ventures."

Czech Republic

    The Czech Companies. The Czech Companies, which consist of two wholly owned
subsidiaries of GTS, offer the only alternative international telephony service
in the Czech Republic, as well as a full range of private data services,
delivered through a combination of a fully digital microwave overlay network
and an international satellite gateway in Prague and GTS-Hungary's VSAT
network. Through an intercompany arrangement with GTS-Hungary, the Czech
Companies provide all of the same VSAT services offered by GTS-Hungary. In
addition, the Czech Companies offer high-speed Internet access service and are
among the leading Internet access providers in the Czech Republic. The Czech
Companies seek to become the second carrier in the Czech Republic and are also
targeting opportunities in Slovakia, based upon the historic relationship
between the Czech and Slovak markets.



                                      52
<PAGE>   53


    The Czech Companies network consist of an earth station linked to
GTS-Monaco Access and to British Telecom, a series of point-to-point and
point-to-multipoint microwave connections providing dedicated access to the
buildings served by the Czech Companies and individual VSATs based on, and
controlled by, GTS-Hungary's hub in Budapest.

    The Czech Companies target customers include real estate developers, hotels
and multinational companies which require international voice or data services
or Internet connectivity, where both GTS's own services and the services of GTS
partners are sold. The Czech Companies provide outgoing international voice
services and high-speed Internet access to large commercial buildings in
Prague. As of December 31, 1997, the Czech Companies had concluded agreements
with building owners to convert PABXs in 25 buildings in Prague. International
voice services are offered at prices similar to those of the Czech PTO. The
Czech market for VSAT services is extremely competitive, with prices at
approximately 50% of those in Hungary for basic services. The Czech Companies
plan to pursue customers who require value-added services which may be offered
at higher prices and better margins.

    The Czech Companies are licensed to provide international satellite and
domestic private voice and data services. They received their operating
licenses in 1994 and 1995 and began offering services in 1995. The licenses
grant permission to install and operate up to 150 earth stations and, upon
application, an additional 150 earth stations. The licenses currently prohibit
the provision of switched voice services and the interconnection to public
voice, telex and data networks and telecommunications networks of other
providers.

    The Czech Companies are the only alternative international telephony
provider licensed in the Czech Republic. As such, their only competitor is SPT
Telecom, the Czech PTO. Should SPT decide to compete aggressively with the
Czech Companies, it has the ability to discount prices below those which could
be easily sustained by the Czech Companies. In data services, Telenor, GITY and
Nextel (a subsidiary of SPT Telecom) are the Czech Companies' three major
competitors for data services in the Czech Republic. GTS believes that its
experience in establishing VSAT services in the region and its emphasis on
integrated voice and data services provides the Czech Companies with a
competitive advantage. Additionally, GTS's transmission facilities and
infrastructure in Hungary and Monaco provide them with a relatively low cost
infrastructure and, as a consequence, greater pricing flexibility than their
competitors. With respect to Internet services, GTS believes that, although
this market consists of a large number of small providers and that SPT Telecom
will seek to enter this market, the dedicated, high-speed infrastructure that
the Czech Companies are installing will provide superior services to its
customers.

ASIA

    Chinese law generally prohibits foreign investment or participation in the
operation of telecommunications services, while Indian law requires foreign
telecommunications operators to conduct certain telecommunications businesses,
including basic switched telephony and cellular services, through joint
ventures that are at least 51% owned by Indian partners. GTS believes that
these restrictive regulations will eventually be liberalized and that its early
entry into these markets and its strong relationships with influential
commercial firms and with local, regional and national-level government
entities will provide it with a strong competitive advantage over competitors
that await more explicit regulatory regimes authorizing direct
telecommunications investments.

China

    GTS participates in the nationwide tourist industry VSAT network through
GTS China Investments LLC, a company in which GTS holds a 75% interest and an
affiliate of a shareholder of the Company owns a 25% interest. See "Certain
Related Party Transactions" in the Company's Proxy Statement for its 1998
Annual Meeting. GTS China Investments LLC holds an indirect 63% interest in

    With respect to V-Tech, in addition to the Company's initial equity
contribution of $3.75 million, GTS committed to fund up to an additional $3.0
million (all of which has been funded by the end of the third quarter of 1997).
The joint venture expires in April 2015, and profits and losses are allocated
according to ownership interests in consideration of funds at risk. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Accounting Methodology -- Profit and Loss Accounting." GTS
currently is evaluating adding additional partners to V-Tech which may reduce
GTS's ownership interest in V-Tech.

    With respect to Beijing Tianmu, in addition to the Company's initial equity
contribution of $8.75 million, GTS is responsible for arranging additional
financing of up to $14.4 million, subject to the approval of the venture's
Board of Directors, the majority of members of which are elected by GTS. The
joint venture expires in March 2021, and profits and losses are allocated
according to ownership interests, in consideration of funds at risk. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Accounting Methodology -- Profit and Loss Accounting."

India

    In India, GTS is following the strategy it implemented in Moscow and is
currently pursuing in Central Europe, in which it initially penetrates the
telecommunications market by developing satellite-based international gateway
networks to provide telecommunications services to targeted business customers.
GTS's operations in India are conducted through C-Datacom International, Inc.
("CDI"), a wholly owned subsidiary which provides digital international private
line communications to and from India for multiple applications, including data
and voice. While not permitted to provide telephony services, CDI is currently
in the process of installing an international gateway switch adjacent to
GTS-Monaco Access's international gateway for the purpose of handling
international traffic.

EMPLOYEES

    On December 31, 1997, GTS and its consolidated subsidiaries employed a
total of 387 persons. On December 31, 1997, the joint ventures in which GTS
participates employed approximately 1,195 persons. The Company believes its
future success will depend on its continued ability to attract and retain
highly skilled and qualified employees. The Company believes that its relations 
with its employees are good.

    Although GTS's employees are not unionized, unions represent employees of
the Company's railroad partners in HER. Under the agreements contemplated
between HER and its railroad partners, some of these employees will be required
to construct and maintain certain portions of the HER network. There can be no
assurances that unionized employees of HER's partners will not experience labor
unrest.

CERTAIN CONSIDERATIONS GENERALLY APPLICABLE TO THE COMPANY'S OPERATIONS

Managing Rapid Growth

    As a result of the Company's past and expected continued growth and
expansion, significant demands have been placed on the Company's management,
operational and financial resources and on its systems and controls. The
Company continues to construct segments of the HER network, expand its
operations within Russia and the CIS and expand into additional geographic and
service markets when business and regulatory conditions warrant. In order to
manage its growth effectively, the Company must continue to implement and
improve its operational and financial systems and controls, purchase and
utilize additional telecommunications facilities and expand, train and manage
its employee base. Inaccuracies in the Company's forecasts of market demand
could result in insufficient or excessive telecommunications facilities and
disproportionate fixed expenses for certain of its operations. There can be no
assurance that the Company will be able to construct and operate the entire HER
network as currently planned, expand with the markets in which its ventures are
currently operating or expand into additional markets at the rate presently
planned by the Company, or that any existing regulatory barriers to such
expansion will be reduced or eliminated. As the Company proceeds with its
development and expansion, there will be additional demands on the Company's
customer support, sales and marketing and administrative resources and network
infrastructure. There


                                      54
<PAGE>   55


can be no assurance that the operating and financial control systems and
infrastructure of the Company and its ventures will be adequate to maintain and
effectively manage future growth. The failure to continue to upgrade the
administrative, operating and financial control systems or the emergence of
unexpected expansion difficulties could materially and adversely affect the
Company's business, results of operations and financial condition.

Risks Relating to Emerging Markets

    Substantially all of the Company's revenue is derived from operations in
emerging markets, where the Company's businesses are subject to numerous risks
and uncertainties, including political, economic and legal risks, such as
unexpected changes in regulatory requirements, tariffs, customs, duties and
other trade barriers, difficulties in staffing and managing foreign operations,
problems in collecting accounts receivable, political risks, fluctuations in
currency exchange rates, foreign exchange controls which restrict or prohibit
repatriation of funds, technology export and import restrictions or
prohibitions, delays from customs brokers or government agencies, seasonal
reductions in business activity, and potentially adverse tax consequences
resulting from operating in multiple jurisdictions with different tax laws,
which could materially adversely impact the Company's business, results of
operations and financial condition.

    The political systems of many of the emerging market countries in which the
Company operates or plans to operate are slowly emerging from a legacy of
totalitarian rule. Political conflict and, in some cases, civil unrest and
ethnic strife may continue in some of these countries for a period of time.
Many of the economies of these countries are weak, volatile and reliant on
substantial foreign assistance. Expropriation of private businesses in such
jurisdictions remains a possibility, whether by an outright taking or by
confiscatory tax or other policies. There can be no assurance that GTS's
operations will not be materially and adversely affected by such factors or by
actions to expropriate or seize its operations. The success of free market
reforms undertaken in certain of the emerging market countries in which the
Company operates is also uncertain, and further economic instability may occur.
These factors may reduce and delay business activity, economic development and
foreign investment.

    Legal systems in emerging market countries frequently have little or no
experience with commercial transactions between private parties. The extent to
which contractual and other obligations will be honored and enforced in
emerging market countries is largely unknown. Accordingly, there can be no
assurance that difficulties in protecting and enforcing rights in emerging
market countries will not have a material adverse effect upon GTS and its
operations. Additionally, the Company's businesses operate in uncertain
regulatory environments. The laws and regulations applicable to GTS's
activities in emerging market countries are in general new and subject to
change and, in some cases, incomplete. There can be no assurance that local
laws and regulations will become stable in the future, or that changes thereto
will not materially adversely affect the operations of GTS. Additionally,
telecommunications regulations in the more developed Western European markets
in which GTS participates are currently undergoing changes initiated by the
Commission of the European Union.

Adequacy of Management, Legal and Financial Controls in Emerging Markets

    Many of the emerging market countries in which the Company operates,
particularly in Russia and the CIS where the Company has to date derived most
of its revenues, are deficient in management and financial reporting concepts
and practices, as well as in modern banking, computer and other control
systems. The Company historically has had difficulty in hiring and retaining a
sufficient number of qualified employees to work in these markets. As a result
of these factors, the Company has experienced difficulty in establishing
management, legal and financial controls, collecting financial data and
preparing financial statements, books of account and corporate records and
instituting business practices that meet Western standards.

    The Company has a policy worldwide of complying with all applicable laws
and seeks to ensure that all persons in its employ comprehend and comply with
such laws. The application of the laws of any particular country, however, is
not always clear, particularly in emerging market countries where commercial
practices differ significantly from practices in the United States and other
Western countries and the legal and regulatory frameworks are less developed.
In addition, some practices, such as the payment of fees for the purpose of
obtaining expedited customs clearance and other commercial benefits, that may
be common methods of doing business in



                                      55
<PAGE>   56

these markets might be unlawful under the laws of the United States. As a
result of the difficulty the Company historically has experienced in emerging
markets in instituting business practices that meet Western reporting and
control standards, it historically has been unable to ascertain whether certain
practices by its ventures, which were not in accordance with Company policy,
were in compliance with applicable U.S. and foreign laws. If it were to be
determined that the Company or any of its ventures were involved in unlawful
practices and were the factual and legal issues relating thereto to be resolved
adversely, the Company or its ventures could be exposed, among other things, to
significant fines, risk of prosecution and loss of its licenses.

    In light of these circumstances, in the second half of 1996 the Company
increased its efforts to improve its management and financial controls and
business practices. The Company recruited a more experienced financial and
legal team, including a new Chief Financial Officer of the Company, a senior
finance officer overseeing all of the regions in which the Company operates, a
senior finance officer for the CIS region, and a senior legal officer for the
CIS region. The Company also established a Treasury group and adopted a more
rigorous Foreign Corrupt Practices Act ("FCPA") compliance program. The Company
has developed and implemented a training program for employees regarding U.S.
legal and foreign local law compliance. The Company also appointed a Compliance
Officer responsible for monitoring compliance with such laws and training
Company personnel around the world. In connection with these developments, the
Company expanded its corporate business practices policy to include, in
addition to compliance with U.S. laws such as the FCPA, compliance with
applicable local laws such as the conflict of interest rules under the 1996
Russian Joint Stock Company Law, currency regulations and applicable tax laws.

    In early 1997, the Company retained special outside counsel to conduct a
thorough review of certain business practices of the Company in the emerging
markets in which the Company operates in order to determine whether
deficiencies existed that needed to be remedied. As a result of this review,
the Company replaced certain senior employees in Russia and instituted
additional and more stringent management and financial controls. As a result of
the review, the Company has not identified any violations of law that
management believes would have a material adverse effect on the Company's
financial condition. There can be no assurances, however, that if the Company
or any of its ventures were found by government authorities to have committed
violations of law that, depending on the penalties assessed and the timing of
any unfavorable resolution, the Company's future results of operations and cash
flows would not be materially adversely affected in a particular period.

    Although the Company believes that this review was properly conducted and
was sufficient in scope, there can be no assurance that all potential
deficiencies have been identified or that the control procedures and compliance
programs initiated by the Company will be effective. If the Company or any of
its ventures are ever found to have committed violations of law, depending on
the penalties assessed and the timing of any unfavorable resolution, the
Company's future results of operations and cash flows could be materially
adversely affected in a particular period. Management believes, however, that
the actions taken during the past twelve months to strengthen the Company's
management, financial controls and legal compliance, coupled with the
implementation of the recommendations from the review and the oversight
provided through the Audit Committee of the Board of Directors of the Company
to ensure compliance, will be adequate to address the recurrence of any past
possible deficiencies.

Dependence on Certain Local Parties; Absence of Control

    Many GTS operations including Sovintel, TeleRoss and GTS Cellular have been
developed in cooperation or partnership with key local parties, such as
regional PTOs. The Company is substantially dependent on its local partners to
provide marketing expertise and knowledge of the local regulatory environment
in order to facilitate the acquisition of necessary licenses and permits. Any
failure by the Company to form or maintain alliances with local partners, or
the preemption or disruption of such alliances by the Company's competitors or
otherwise, could adversely affect the Company's ability to penetrate and
compete successfully in the emerging markets it operates in or enters. In
addition, in the uncertain legal environments in which GTS operates, certain
GTS businesses may be vulnerable to local government agencies or other parties
who wish to renegotiate the terms and conditions of, or terminate, their
agreements or other understandings with GTS.

    While the Company may have the right to nominate key employees, direct the
operations and determine the strategies of such joint ventures, under the terms
of their respective constituent documents, the Company's partners

                                      56
<PAGE>   57


in some of the ventures have the ability to frustrate the exercise of such
rights. Significant actions by most of GTS's ventures, such as approving
budgets and business plans, declaring and paying dividends, and entering into
significant corporate transactions effectively require the approval of GTS's
local partners. Further, the Company would be unlikely as a practical matter to
want to take significant initiatives without the approval of its joint venture
partners. Accordingly, the absence of unilateral control by the Company over
the operations of its joint ventures could have a material adverse effect on
the Company.

    In addition, the Company and its venture partners frequently compete in the
same markets. For example, Rostelecom, GTS's partner in Sovintel, is the
dominant international and domestic long distance carrier in Russia. In
addition, many of the regional telephone companies partnered with GTS in the
TeleRoss Ventures offer cellular services in direct competition with certain of
the operations of GTS Cellular. Such competition with its partners may lead to
conflicts of interest for GTS and its partners in the operations of their
ventures. There can be no assurance that any such conflicts will be resolved in
favor of GTS. In addition, the combination under Svyazinvest of the Russian
government's majority interest in Rostelecom and 85 of the regional telephone
companies gives Svyazinvest a majority interest in entities that provide
international and domestic long distance and local telecommunications services
throughout Russia and may expose the Company to more coordinated competition
from its partners in the Russian telecommunications market.

Government Regulation

    As a multinational telecommunications company, GTS through its ventures is
subject to varying degrees of regulation in each of the jurisdictions in which
its ventures provide services. Local laws and regulations, and the
interpretation of such laws and regulations, differ significantly among the
jurisdictions in which the Company and its ventures operate. There can be no
assurance that future regulatory, judicial and legislative changes will not
have a material adverse effect on the Company, that regulators or third parties
will not raise material issues with regard to the Company's or its ventures'
compliance or noncompliance with applicable regulations or that any changes in
applicable laws or regulations will not have a material adverse effect on the
Company or any of its ventures.

    Many of GTS's ventures require telecommunications licenses, most of which
have been granted for periods of three to ten years. The terms and conditions
of these licenses may limit or otherwise affect the ventures' scope of
operations. The Company has had favorable experience obtaining, maintaining and
renewing licenses in the past. However, there can be no assurance that it will
be able to obtain, maintain or renew licenses to provide the services it
currently provides and plans to provide, that such licenses will be issued or
renewed on terms or with fees that are commercially viable, or that licenses
required by future ventures can be obtained by the Company or its partners. The
loss of or a substantial limitation upon the terms of these telecommunications
licenses could have a material adverse effect on the Company. See each section
under "Business" entitled "Licenses and Regulatory Issues."

    A substantial portion of HER's strategy is based upon the timely
implementation of regulatory liberalization of EU telecommunications market on
January 1, 1998 under existing European Community ("EC") directives. Although
EU member states have a legal obligation to liberalize their markets in
accordance with their requirements, certain more detailed aspects of the EU
regulatory framework to apply in the liberalized environment after January 1,
1998 still remain to be adopted. In addition, Ireland, Portugal, Spain,
Luxembourg and Greece have been granted extensions from the January 1, 1998
deadline. There can be no assurance that each EU member state will proceed with
the expected liberalization on schedule, or at all, or that the trend toward
liberalization will not be stopped or reversed in any of the countries.
Accordingly, HER faces the risk that it will establish the HER network and make
capital expenditures in a given country in anticipation of regulatory
liberalization which does not subsequently occur.

    In order to give effect to EC directives in each member state, national
governments must pass legislation liberalizing their respective markets. This
applies not only to the liberalization requirements set out in existing EC
directives, but also to requirements set out in directives which have yet to be
adopted. The implementation of EC directives in the telecommunications sector
has been inconsistent or ambiguous in some EU member states. Such
implementation could limit, constrain or otherwise adversely affect HER's
ability to provide certain services. Furthermore, national governments may not
necessarily pass legislation implementing an EC directive in the form 


                                      57
<PAGE>   58

required, or at all, or may pass such legislation only after a significant
delay. Even if a national legislature enacts appropriate regulation within the
time frame established by the EU, there may be significant resistance to the
implementation of such legislation from PTOs, regulators, trade unions and
other sources. Further, HER's provision of services in Europe may be materially
adversely affected if any EU member state imposes greater restrictions on
non-EU international services than on international services within the EU.
These and other potential obstacles to liberalization could have a material
adverse effect on HER's operations by preventing HER from establishing its
network as currently intended, as well as a material adverse effect on the
Company.

Competition

    GTS faces significant competition in all of its existing telecommunications
businesses and for the types of acquisition and development opportunities it
seeks in both emerging and Western European markets. GTS's competition in these
markets includes national PTOs, multinational telecommunications carriers,
other telecommunications developers and certain niche telecommunications
providers. In addition, certain of the Company's joint venture partners,
including Rostelecom and the regional telephone companies in Russia, certain of
HER's rail-based shareholders and other entities in the emerging markets in
which the Company operates, are also competitors of the Company. As a result of
the recent combination under Svyazinvest of the government's majority interest
in Rostelecom and 85 of the regional telephone companies, the Company may in
the future be subject to more coordinated competition from its partners in the
Russian telecommunications market. Although the Company believes it has a
favorable and cooperative relationship with its joint venture partners, there
can be no assurance that these partners will continue to cooperate with the
Company in the future or that they will not increase competitive pressures on
the Company. Any measures taken by the partners that reduce the level of
cooperation with the Company could jeopardize the Company's ability to
participate in the management and operation of its joint ventures and could
have a material adverse effect on the Company.

    HER also competes with respect to its "point-to-point" transborder service
offering against circuits currently provided by PTOs through International
Private Leased Circuits. In addition, the liberalization of the European
telecommunications market is likely to attract additional entrants to both the
"point-to-point" and other telecommunications markets. There can be no
assurance that HER will compete effectively against its current or future
competitors. See also "---Western Europe - HER - Competition" for a discussion
of the plans of WorldCom, Viatel and Esprit to build fiber optic networks in
Western Europe.

    Many of the Company's competitors have technical, financial, marketing and
other resources substantially greater than those of GTS. There can be no
assurance that the Company will be able to overcome successfully the
competitive pressures to which it is subject, both in the markets in which it
currently operates and in markets into which it might expand. See each section
under "Business" entitled "Competition." In addition, many of the Company's
current and potential competitors are not subject to, or constrained by the
prohibitions of, the FCPA, including the prohibition against making payments to
government officials in order to obtain commercial benefits. The Company is
subject to and seeks to comply with the limitations and prohibitions of such
law, and accordingly may be subject to competitive disadvantages to the extent
that its competitors are able to secure business, licenses or other
preferential treatment through the making of such payments. Accordingly, there
can be no assurances that the Company will be able to compete effectively
against companies free from such limitations in the emerging markets where such
commercial practices are commonplace. See "-- Adequacy of Management, Legal and
Financial Controls in Emerging Markets."

Currency and Exchange Risks

    All of GTS's operations are conducted outside the United States. A
substantial portion of the Company's anticipated revenues (as well as the
majority of its operating expenses) will be in foreign currency. As a result,
the Company will be subject to significant foreign exchange risks. In
particular, GTS's ventures in countries whose currencies are considered "soft
currencies" subject the Company to the risk that it will accumulate currencies
which may not be readily convertible into hard currency and which may be
subject to significant limitations on repatriation. The Company does not enter
into hedging transactions to limit its foreign currency risk exposure, although
the Company may implement such practices in the future. There can be no
assurance that GTS's operations 



                                      58
<PAGE>   59

will not be adversely affected by such factors. In addition, these factors may
limit the ability of the Company to reinvest earnings from ventures in one
country to fund the capital requirements of ventures in other countries.

Dependence on Effective Information Systems

    To complete its billing, the Company must record and process massive
amounts of data quickly and accurately. While the Company believes its
ventures' management information systems are currently adequate, certain of
such systems will have to grow as the ventures' businesses expand. The Company
believes that the successful expansion of its information systems and
administrative support will be important to its continued growth, its ability
to monitor and control costs, to bill customers accurately and in a timely
fashion and to achieve operating efficiencies. There can be no assurance that
the Company will not encounter delays or cost-overruns or suffer adverse
consequences in implementing these systems. Any such delay or other malfunction
of the Company's management information systems could have a material adverse
effect on the Company's business, financial condition and results of
operations.

Technology

    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 Company obtains
telecommunications equipment from a number of vendors, upon whom it is
dependent for the adaptation of such equipment to meet varying local
telecommunications standards. The cost of implementation of emerging and future
technologies could be significant. There can be no assurance that the Company
will maintain competitive services or that the Company will obtain appropriate
new technology on a timely basis or on satisfactory terms. Any failure by the
Company to maintain competitive services or obtain new technologies could have
a material adverse effect on the Company's business, financial condition and
results of operations.

    Development and operation of the HER network are also subject to certain
technological risks. The network has been designed to utilize SDH technology.
While SDH represents an advanced, new transmission technology, HER's ability to
upgrade technology from this platform may be important in establishing and/or
maintaining a cost advantage over competitive carriers. There can be no
assurance that the HER network will achieve the technical specifications for
which it was designed or that HER will be able to upgrade the network as
technological improvements in telecommunications equipment are introduced.
Failure to achieve current specifications for, or future upgrades of, the
network may materially and adversely affect the viability of the HER network
and could have a material adverse effect on the business and prospects of GTS.

Difficulty in Obtaining Reliable Market Information

    The Company operates in markets in which it is difficult to obtain reliable
market information. The Company's business planning has been based on certain
assumptions concerning subscriber base, usage levels, pricing and operating
expenses based on the Company's experience and the Company's own investigation
of market conditions in the emerging market countries in which it operates. No
assurances can be given as to the accuracy of such assumptions, and such
assumptions may not be indicative of the actual performance of the Company's
operations.

Enforceability of Judgments

    Substantially all of the assets of the Company (including all of the assets
of the Company's operating ventures) are located outside the United States. As
a result, it will be necessary for investors to comply with foreign laws in
order to enforce judgments obtained in a United States court (including those
with respect to federal securities law claims) against the assets of the
operating ventures, including foreclosure upon such assets, and there can be no
assurance that any U.S. judgments would be enforced under any such foreign
laws.

    Kbps -- Kilobits per second, which is a measurement of speed for digital
signal transmission expressed in thousands of bits per second.

    Local Area Network (LAN) -- The interconnection of computers for the
purpose of sharing files, programs and peripheral devices such as printers and
high-speed modems. LANs may include dedicated computers or file servers that
provide a centralized source of shared files and programs. LANs are generally
confined to a single customer's premises and may be extended or interconnected
to other locations through the use of bridges and routers.

    Local Loop -- The local loop is that portion of the local telephone network
that connects the customer's premises to the local exchange provider's central
office or switching center. This includes all the facilities starting from the
customer premise interface which connects to the inside wiring and equipment at
the customer premise to a terminating point within the switching wire center.

    Mbps -- Megabits per second, which is a measurement of speed for digital
signal transmission expressed in millions of bits per second.

ITEM 2.           PROPERTIES

    The Company leases, under long-term leases, office space to serve as sales
office and/or administrative facilities, including its 15,000 square-foot
headquarters in McLean, Virginia with a five year lease expiring December,
2000. The Company maintains regional headquarters offices in Moscow and
Budapest, as well as facilities in London. HER is headquartered just outside of
Brussels, Belgium.

    HER leases, under long-term leases, portions of railroad, utility and other
rights-of-way for its fiber-optic routes. HER is creating a fiber optic network
consisting of optical fiber pairs, which are leased under long-term leases, and
technical sites leased under long-term leases. See "Business -Western Europe -
HER."

ITEM 3.           LEGAL PROCEEDINGS

    In addition to routine legal proceedings incidental to the conduct of its
business, the Company, GTS-Hungaro and GTS-Hungary are named as defendants in
an action captioned USH Ventures and USH Telecom, L.L.C. v. Global TeleSystems
Group, Inc. and GTS-Hungaro, Inc., Civil Action No. 97C-08-86, commenced in
August 1997, which is currently pending in the Superior Court of the State of
Delaware in and for New Castle County. The complaint alleges breach of contract
and interference with a business relationship. While it is not possible at this
time to make a meaningful assessment of the outcome of this litigation, based
upon information currently available and upon consultation with counsel, the
Company does not believe that the outcome of this litigation will have a
material adverse effect upon the financial condition of the Company.

    On March 27, 1998, V-Tech brought a claim for approximately $1.1 million
against Gilat Satellite Networks, Ltd. ("Gilat"), the vendor of a Ku-band VSAT
hub and system which V-Tech purchased in 1996, in an arbitration proceeding
under the Rules of Arbitration of the ICC International Court of Arbitration.
V-Tech has demanded in the request for arbitration that Gilat accept return of
the equipment, which V-Tech has not accepted or commissioned because it has
failed to meet contract specifications, and refund purchase amounts already paid
under the contract, plus other sums. Gilat has previously asserted that the
equipment meets specifications and demanded that V-Tech pay the balance due
under the contract, approximately $400,000. It is not possible at this time to
make an assessment of the outcome of the arbitration proceeding.

ITEM 4.           SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS

         During the fourth quarter of 1997 and first quarter of 1998, the
Company, in lieu of calling stockholders meetings, solicited written consents
from its common stockholders with respect to the following three proposed
actions:

1) The Company solicited written consents from its common stockholders of record
   on November 14, 1997, regarding a proposal to amend the Company's Certificate
   of Incorporation, as amended (the "Charter"), to:

    a)   change the par value per share of the Company's common stock from
         $0.0001 to $0.10;

    b)   effect a 3-for-2 split of the Company's common stock; and

    c)   increase the authorized common stock from 60 million to 135 million
         shares.

    As of December 1, 1997, holders representing 17,847,036 shares of the
Company's common stock, or 71% of the outstanding shares of common stock,
submitted written consents approving such proposed amendment of the Charter.
The Company did not receive any responses "against," or abstentions with
respect to, the proposed amendment.

2) The Company solicited written consents from its common stockholders of
   record on December 10, 1997 regarding a proposal to amend its Charter to:

    a)   classify its Board of Directors into three classes and stagger the
         election of each such class for three-year terms commencing at the
         annual stockholders meetings to be held in 1998, 1999 and 2000;

    b)   eliminate the ability of the stockholders to act by written consent;
         and

    c)   provide that the provisions of the charter set forth in (a) and (b)
         above can be amended only by an affirmative vote of 75% of the shares
         present and eligible to vote (the "Locking Provision").

    As of January 29, 1998, holders representing 20,627,807 shares of the
Company's common stock, or 55% of the outstanding shares of common stock,
submitted written consents approving such proposed amendments of the Charter.
The Company received 2,014,287 votes, or 5% of the outstanding common stock,
against the proposed amendment. The Company did not receive any abstentions
with respect to the proposed amendment.



                                       64
<PAGE>   65

2)  The Company solicited written consents from its common stockholders of
    record on January 12, 1998 regarding a proposal to amend the Charter to
    require an affirmative vote of 75% of the shares present and eligible to
    vote to amend the Locking Provision. As of January 29, 1998 holders
    representing 23,595,352 shares of the Company's common stock, or 63% of the
    outstanding shares of common stock, submitted written consents approving
    such proposed amendment of the Charter. The Company did not receive any
    responses "against," or abstentions with respect to, the proposed amendment.

                                     PART II

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

    The listing of the Company's common stock on the NASDAQ National Market
commenced on February 5, 1997. The high and low sale prices of the Company's
common stock as reported by the NASDAQ National Market from February 5, 1998
through February 27, 1998 were:

               High $38.75;      Low $25

As of February 27, 1997, the Company's common stock was held by 179 holders of
record.

    The Company has not paid any dividend on its common stock and does not
intend to pay dividends in the foreseeable future. In addition, the indenture
governing the Company's 9-7/8% Senior Notes due 2005 contains restrictions on
the making of restricted payments (in the form of the declaration or payment of
certain dividends or distributions, the purchase, redemption or other
acquisition of any capital stock of the Company, the voluntary prepayment of
pari passu or subordinated indebtedness and the making of certain investments,
loans and advances) unless no Default or Event of Default (each, as defined in
such indenture) exists, its leverage ratio does not exceed 6.0 to 1.0 and such
restricted payments do not exceed the Basket (as defined in such indenture).
Moreover, GTS is a holding company which has no significant business operations
or assets other than its interests in joint ventures and its subsidiaries.
Accordingly, GTS must rely entirely upon distributions from the joint ventures
and its subsidiaries and investments to generate the funds necessary to pay any
dividends. The joint ventures and the Company's subsidiaries are separate and
distinct legal entities which have no obligation, contingent or otherwise, to
pay any amount to the Company, whether by dividends, loans or other payments,
except for payments under certain intercompany indebtedness. See "Business." In
addition, should the Company receive dividends or other distributions from its
joint ventures, subsidiaries or investments, the ability of the Company to
repatriate such profits and capital is dependent upon the provisions of the
applicable foreign investment and exchange laws and availability of foreign
exchange in sufficient quantities in those countries. The amount of such
dividends and other distributions from these entities will be affected by the
current tax systems in these jurisdictions, primarily the provisions relating
to corporate profits and withholding taxes. Furthermore, because consent is
required of the venture partners in some of the Company's joint ventures for
distributions from such joint ventures, the Company's ability to receive
dividends and other distributions is to some degree dependent on cooperation
from its joint venture partners. Thus, there can be no assurance that the
Company will be able to realize benefits from its joint ventures, subsidiaries
and investments through the receipt of dividends or other distributions at such
times and amounts it desires. In addition, the Company and certain operating
subsidiaries of the Company may enter into future financings, the terms of
which may include dividend restrictions.

    The foregoing reflects a 3-for-2 common stock split and an increase in the
par value per share of common stock to $0.10 effective December 1, 1997.

    During the year ended December 31, 1997 the Company issued securities which
were not registered under the Securities Act of 1933, as amended (the
"Securities Act") as follows:

    On July 14, 1997 and July 31, 1997, the Company issued an aggregate
$141,295,000 of its Senior Subordinated Convertible Bonds due 2000, convertible
into the common stock, par value $0.10 per share, at a purchase price of 100%,
pursuant to a subscription agreement. UBS Securities LLC, Donaldson, Lufkin &
Jenrette Securities 



                                       65
<PAGE>   66

Corporation and Merrill Lynch & Co. acted as managers in the offering and the
aggregate discount was $5,651,800. The securities were sold to a limited number
of qualified institutional buyers as defined in Rule 144A under the Securities
Act and to non-U.S. persons outside the United States. Exemption from
registration was claimed under Rule 144A and Regulation S of the Securities Act.
On February 10, 1998, the Company completed a "Complying Public Equity
Offering," as defined in the indenture for such Bonds, and, as a result, such
Bonds became convertible into the common stock at a conversion price of $20 per
share.

    On August 15, 1997, August 29, 1997 and September 5, 1997, the Company
issued an aggregate 2,502,686 shares of common stock, par value $0.10 per
share, at a purchase price of $15.67 per share, for an aggregate offering price
of $39.2 million, pursuant to a stock purchase agreement. In addition to (i)
certain investment funds and (ii) certain individual private investors, these
shares were issued to certain members of management and various entities
affiliated with certain members of management. Exemption from registration was
claimed under Section 4(2) of the Securities Act regarding transactions by an
issuer not involving any public offering.

    On August 29, 1997, the Company issued $3.5 million of its Senior
Subordinated Convertible Bonds due 2000, convertible into the common stock, par
value $0.10 per share, at a purchase price of 100%. In addition to (i) certain
investment funds and (ii) certain individual private investors, these shares
were issued to certain members of management and various entities affiliated
with certain members of management. Exemption from registration was claimed
under Section 4(2) of the Securities Act regarding transactions by an issuer
not involving any public offering. See the discussion above concering the terms
of conversion of these Bonds.

    On September 26, 1997, the Company filed a registration statement
(Commission file no. 333-36555) (the "Stock Registration Statement") with the
Securities and Exchange Commission (the "Commission") to offer and sell to the
public, in an underwritten offering, 11,100,000 shares of its common stock, par
value $0.10 per share (the "Stock Offering"). Merrill Lynch & Co., Donaldson,
Lufkin & Jenrette Securities Corporation, UBS Securities LLC, Lehman Brothers
Inc. and Furman Selz LLC acted as the managers of the U.S. portion (7,400,000
shares) of the Stock Offering. Merrill Lynch International, UBS Limited,
Donaldson, Lufkin and Jenrette International, Lehman Brothers International
(Europe) and Baring Brothers Limited (as agent for ING Bank N.V.) acted as the
managers of the international portion (3,700,000 shares) of the Stock Offering.
The Stock Registration Statement was declared effective by the Commission on
February 5, 1998. In connection with the Stock Offering, the managing
underwriters exercised an overallotment option of 1, 665,000 shares. The Stock
Offering has terminated. The Company realized from the sale of a total of
12,765,000 common shares at $20 per share net proceeds from the Stock Offering,
including shares issued pursuant to exercise of the overallotment option, of
$238,705,500, after payment of $16,594,500 in underwriting discounts. On
December 23, 1997, the Company also filed a registration statement (Commission
file no. 333-43155) (the "Debt Registration Statement") to offer and sell to the
public, in an underwritten offering, senior notes due 2005 of the Company (the
"Debt Offering"). Donaldson, Lufkin & Jenrette Securities Corporation, Merrill
Lynch & Co. and UBS Securities acted as managers of this offering. The Debt
Registration Statement was declared effective by the Commission on February 5,
1998. The Debt Offering has terminated and the Company issued $105 million
aggregate principal amount of 9-7/8% Senior Notes due 2005 (the "Senior Notes").
The Company realized from the sale of the Senior Notes net proceeds of $82.3
million, after payment of underwriting discounts and commissions of $3,150,000,
and the deposit of $19.6 million in escrow to cover the first four scheduled
payments of interest on the Senior Notes. In February 1998, the Company
applied a portion of the net proceeds of the Offerings, approximately $85.2
million, to repay the outstanding principal of, and accrued interest on, certain
loans from related parties. See Note 5 --- Debt Obligations --- the Company's
audited consolidated financial statements for a description of such related
party loans. The Company will disclose additional information regarding expenses
incurred in connection with, and application of net proceeds of, the Offerings
in its quarterly report on Form 10-Q for the quarter ended March 31, 1998.

<PAGE>   67

    The following selected historical consolidated financial data as of and for
the years ended December 31, 1993, 1994, 1995, 1996 and 1997 are derived from
the Company's audited Consolidated Financial Statements. The selected financial
data presented below should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the audited Consolidated Financial Statements and related notes thereto
appearing elsewhere in this Prospectus.

Under generally accepted accounting principles, many of the Company's ventures
are accounted for by the equity method of accounting. Under this method, the
operating results of the ventures are included in the Company's Consolidated
Statement of Operations as a single line item, "Equity in (losses) earnings of
ventures." The Company recognizes 100% of the losses in ventures where the
Company bears all of the financial risk (which includes all of the Company's
significant ventures except for Sovintel and, historically, HER). Also, the
assets, liabilities and equity of the ventures are included in the Company's
Consolidated Balance Sheets as a single line item "Investments in and Advances
to Ventures." See Note 3 to the Company's audited Consolidated Financial
Statements and "Management's Discussion and Analysis of Financial Condition and
Results of Operations --Overview." Financial information about the Company's
equity ventures is included below under "Supplemental Information -- Selected
Historical Financial Data -- Combined Equity Investments."

(1)   As a result of the Company's increase in ownership interest and amendment
      to the HER Shareholders Agreement that was completed on July 16, 1997,
      the Company accounts for its ownership interest in HER under the
      consolidation method of accounting. Prior to this date, the Company
      accounted for HER under the equity method of accounting.

(2)   The above unaudited pro forma information gives effect to the
      underwritten public offerings by the Company of common stock and debt
      securities consummated in February 1998, as though the transactions had
      occurred on December 31, 1997. The adjustments include the raising of
      $255.3 million from the sale of 12.8 million

     shares of common stock at an issue price of $20.00 per share. In addition,
     the Company issued $105.0 million in senior notes. Approximately $85.2
     million of the net proceeds were used to repay the related party debt
     obligations. See Note 15, Audited Financial Statements of the Company.

                 SUPPLEMENTAL INFORMATION -- SELECTED HISTORICAL
                  FINANCIAL DATA -- COMBINED EQUITY INVESTMENTS

The following unaudited selected historical financial data -- equity
investments for the years ended December 31, 1995, 1996 and 1997, are derived
from the Company's financial records. It is intended to supplement the
aforementioned selected historical consolidated financial data. The financial
data set forth below represents 100% of the results of operations for each of
the entities.

    The Company believes that this information provides additional insight on
the Company's unconsolidated equity method investments. Generally accepted
accounting principles prescribe inclusion of revenues and expenses for
consolidated interests (generally interests of more than 50%, absent some other
factors), but not for equity interests (generally interests of 20% to 50%) or
cost interests (generally interests of less than 20%). Equity accounting
ordinarily results in the same net income as consolidation; however, the net
operating results are reflected on one line within the income statement.

    The following is a discussion of the financial condition and results of
operations of the Company as of December 31, 1997, 1996 and 1995 and for the
years ended December 31, 1997, 1996, 1995. The following discussion should be
read in conjunction with the Company's 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,
(iii) changes in the Company's competitive environment and (iv) the performance
of future equity-method investments, contain forward-looking statements
concerning the Company's 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 the Company's results of
operations are the potential risk of delay in implementing the Company's
business plan; the political, economic and legal aspects of the markets in
which the Company operates; competition and the Company's 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 of
the Company made by or on behalf of the Company, 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 the Company undertakes 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, management
cannot assess the impact of each such factor on the Company's 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

    Business. GTS is a provider of a broad range of telecommunications services
to businesses, other telecommunications service providers and consumers in
Russia and the CIS, Central Europe and Asia. In Western Europe, through HER,
GTS is developing and operating the initial segment of a pan-European high
capacity fiber optic network which is designed to interconnect a majority of
the largest Western and Central European cities and to transport international
voice, data and multimedia/image traffic for other carriers throughout Western
and Central Europe. GTS's strategy to develop its businesses generally has been
to establish joint ventures with a strong local partner or partners while
maintaining a significant degree of operational control. The Company's business
activities consist of the ownership and operation of (i) international long
distance businesses, which operate through 


                                       69
<PAGE>   70

international gateways that provide international switching services and
transmission capacity, (ii) local access networks, which provide local telephone
service, (iii) cellular networks, which provide wireless telecommunications
services, (iv) a domestic long distance business, (v) data networks and (vi)
carriers' carrier networks, which provide high volume transmission capacity to
other carriers.

    The Company began to acquire interests in numerous telecommunications
ventures beginning in 1994 and continued to acquire such interests throughout
1995 and 1996. Ventures with significant financial results in 1994 included
Sovintel (an international long distance and domestic and local access
telecommunications service provider) and GTS-Hungary (a VSAT network
telecommunications service provider); ventures that incurred start-up costs
associated with building out their business infrastructure in 1994 included
Sovam (a data and internet telecommunications service provider) and EuroHivo (a
paging telecommunications service provider). In 1995, TeleRoss (a domestic long
distance telecommunications service provider) and GTS Cellular (a basic
cellular telecommunications service provider) began operations and expanded
into numerous regions within the CIS by the end of 1996. Telecommunications of
Moscow ("TCM") (a local access telecommunications service provider) began
operations in 1996. HER (a carriers' carrier telecommunications service
provider) began its network build-out in 1995, began limited operations at the
end of 1996 and expects to continue to develop its network during 1998 and
beyond. The fact that these ventures are in various stages of development
affects the discussion of comparative results below. See "Business."

    GTS has invested significantly in its ventures through capital
contributions and loans. In addition, the Company has made a significant
commitment to its businesses and ventures through the provision of management
assistance and training. GTS has also incurred significant expenses in
identifying, negotiating and pursuing new telecommunications opportunities. GTS
and certain of its ventures are experiencing continuing losses and negative
operating cash flow primarily because the businesses are in the developmental
and start-up phases of operations. Management recognizes that the Company must
generate additional capital resources in order to continue its operations and
meet its new development initiatives. The ultimate recoverability of the
Company's investments in and advances to ventures is dependent on many factors
including, but not limited to, the ability of the Company to obtain sufficient
financing to continue to meet its capital and operational commitments, the
economies of the countries in which it does business and the ability of the
Company to maintain the necessary telecommunications licenses.

    The Company's businesses are developing rapidly. Some of the businesses
operate in countries with emerging economies which have uncertain economic,
political and regulatory environments. The general risks of operating
businesses in the CIS and other developing countries include the possibility
for rapid change in government policies including telecommunications
regulations, economic conditions, the tax regime and foreign currency
regulations. See "Business--Certain Considerations Applicable to the Company's
Operations in Russia and the CIS" and "--Certain Considerations Generally
Applicable to the Company's Operations."

ACCOUNTING METHODOLOGY

    Accounting for Business Ventures. Wholly-owned subsidiaries and
majority-owned ventures where the Company has unilateral operating and
financial control are consolidated. Those ventures where the Company exercises
significant influence, but does not exercise unilateral operating and financial
control, are accounted for by the equity method. The Company has certain
majority-owned ventures that are accounted for by the equity method as a result
of minority shareholder rights, super-majority voting conditions or other
governmentally imposed uncertainties so severe that they prevent the Company
from obtaining unilateral control of the venture.

    Profit and Loss Accounting. The Company recognizes profits and losses in
accordance with its underlying ownership percentage or allocation percentage as
specified in the agreements with its partners; however, the Company recognizes
100% of the losses in ventures where the Company bears all of the financial
risk (which includes all of the Company's significant ventures except for
Sovintel and, historically, HER). Accordingly, the portion of the losses that
would normally be assigned to the minority interest partner ("Excess Losses")
is recognized by the Company. When such ventures become profitable, the Company
recognizes 100% of the profits until such time as the Excess Losses previously
recognized by the Company have been recovered. As of December 


                                       70
<PAGE>   71


31, 1997, $5.3 million and $10.0 million represent the net unrecovered Excess
Losses for the Company's consolidated and equity method investments,
respectively, that is expected to favorably benefit future period results from
operations upon the Company's existing business ventures becoming profitable.
This accounting policy was adopted prior to 1995; however, 1995 was the first
year that the excess loss amount was deemed material for recognition within the
Company's accounting records. For the period from January 1, 1997, through
August 31, 1997, the Company recognized 100% of HER's losses due to GTS being
the financing partner during this period. As a result of HER's issuance of $265
million aggregate principal amount of senior notes (of which $56.6 million was
placed in escrow for the first two years' interest payments) in August 1997, the
Company no longer considers itself as the financing partner.

    Inter-Affiliate Transactions. Several of the Company's ventures have
entered into business arrangements through which they provide integrated
solutions for their customers by leveraging each others' telecommunications
infrastructure. These arrangements have historically been focused primarily
within a region; however, as GTS has increased its geographic coverage and
telecommunication capabilities, these arrangements have expanded between
regions. In accordance with generally accepted accounting principles, all
significant intercompany accounts and transactions are eliminated upon
consolidation.

    Turnover Taxes. The Company's ventures within the CIS region incur a 4%
turnover tax that is based on the revenues earned. The Company includes these
taxes as a component of its operating expenses, since these taxes are
incidental to the revenue cycle.

    The following table summarizes the accounting methodology for the principal
business ventures through which the Company conducts its business.

(1) The TeleRoss Operating Company is comprised of two wholly-owned holding
    companies and a 99% owned subsidiary that operates a domestic long distance
    network and holds the applicable operating license for TeleRoss and performs
    the customer invoicing and collection functions for telecommunications
    services. TeleRoss Operating Company is accounted for under the
    consolidation method of accounting because GTS has unilateral control over
    the operations and management decisions. TeleRoss Operating Company's
    operations are further discussed in "--Results of Operations--Consolidated
    Ventures" and "Business--Russia and the CIS--TeleRoss." A significant
    portion of TeleRoss Operating Company's costs of revenue consists of
    settlement fees paid to the TeleRoss Ventures, with such fees being recorded
    as revenue by the TeleRoss


                                       71

    Ventures. In 1996 and 1997, all of the TeleRoss Ventures' revenue was
    derived from such fees. Any decline in the business or operations of the
    TeleRoss Ventures would have a material adverse effect on the results of
    TeleRoss Operating Company.

(2) TeleRoss Ventures is comprised of thirteen operating joint ventures that are
    50% beneficially owned by GTS, which originate traffic and provide local
    termination of calls through agency arrangements with TeleRoss Operating
    Company. GTS does not exercise unilateral control over the TeleRoss
    Ventures, and therefore they are appropriately accounted for under the
    equity method of accounting. TeleRoss Ventures' operations are further
    discussed in "--Results of Operations--Non-Consolidated Ventures."

(3) GTS purchased the remaining 33% interest in Sovam in February 1998.

(4) GTS conducts its cellular operations through (i) Vostok Mobile, a wholly
    owned GTS venture that owns between 50% and 70% of a series of 12 cellular
    joint ventures in various regions in Russia, (ii) PrimTelefone, a 50% owned
    venture in Vladivostok, Russia and (iii) Bancomsvyaz, an approximately 25%
    beneficially owned venture in Kiev, Ukraine.

(5) As of July 16, 1997, HER is accounted for by the consolidation as opposed to
    the equity method of accounting.

RESULTS OF OPERATIONS -- CONSOLIDATED VENTURES

    Management's discussion included within "--Results of
Operations--Consolidated Ventures" reflects the following significant operating
ventures: TeleRoss Operating Company, GTS-Hungary, the Czech Companies and HER
(for 1997). See "Results of Operations--Non-Consolidated Ventures (Equity
Investees)" for a discussion of the operating results of Sovintel, TCM, Sovam,
TeleRoss Ventures, GTS Cellular, HER (prior to 1997), GTS-Monaco Access,
EuroHivo and the Asia business ventures.

    Revenue. The Company's consolidated revenue was $47.1 million, $24.1
million and $8.4 million for the years ended December 31, 1997, 1996, and 1995,
respectively. The growth in revenue was attributable to the commencement in
1995 of commercial operations by TeleRoss Operating Company, as well as the
continued expansion of services and customer base in Central Europe, and HER's
initial Amsterdam to Brussels route and further expansion to London and Paris
during 1997.

    The CIS region's consolidated revenue was $27.1 million, $12.7 million, and
$3.8 million for the years ended December 31, 1997, 1996 and 1995 respectively.
TeleRoss Operating Company generated revenue of $24.7 million, $9.2 million and
$3.8 million, representing 91.1%, 72.4% and 100% of the region's consolidated
revenue for the years ended December 31, 1997, 1996 and 1995, respectively.
Service revenue represented 81.8%, 64.1% and 21.1% of TeleRoss Operating
Company's revenue for the years ended December 31, 1997, 1996 and 1995,
respectively, with the balance of its revenue in such periods principally
represented by installation and equipment sales. The growth in revenue was a
result of increased traffic volume generated by the TeleRoss Ventures as they
expanded to 13 cities for the year ended December 31, 1997, added customers in
existing cities and installed several VSATs at customer locations outside of
cities in which they have a presence.

    Within the Central Europe region, GTS-Hungary and the Czech Companies
accounted for 100% of the revenue earned, of which GTS-Hungary and the Czech
Companies provided $8.5 million and $5.1 million of the Company's consolidated
revenue in 1997, respectively, compared to $6.9 million and $2.3 million in
1996, respectively, and $4.2 million and $0.3 million in 1995, respectively.
The growth in revenue of GTS-Hungary from 1995 to 1997 was due to the expansion
of its customer base and the introduction of microwave technology services. The
Hungary state lottery accounted for 50.6%, 55.3% and 65.0% of GTS-Hungary's
revenue in 1997, 1996 and 1995, respectively. The growth in revenue of the
Czech Companies was generated through increases in voice traffic carried from
twenty-five buildings at December 31, 1997, as compared to sixteen buildings at
December 31, 1996.

    All of Western Europe's consolidated revenue of $5.4 million for the year
ended December 31, 1997 was derived from HER.


                                       72

    Gross Margin. GTS's consolidated gross margin was $4.4 million, or 9.3% of
revenue, for the year ended December 31, 1997, $5.2 million, or 21.6% of
revenue, for the year ended December 31, 1996 and $0.02 million, or 0.0% of
revenue, for the year ended December 31, 1995.

    The CIS region had a gross margin of $4.0 million, $0.8 million and $(0.9)
million for the years ended December 31, 1997, 1996 and 1995, respectively.
TeleRoss Operating Company had a gross margin of $3.5 million, or 14.2% of
revenues, for the year ended December 31, 1997 and a negative gross margin of
$(1.0) million for each of the years ended December 31, 1996 and 1995, which
was the result of the high fixed cost component of its network hub in Moscow.
GTS-Hungary and the Czech Companies comprised 100% of the Central Europe
region's gross margin. GTS-Hungary had a gross margin of $3.5 million, $3.0
million, and $1.7 million, representing 41.2%, 43.4%, and 40.5% of
GTS-Hungary's revenue for the years ended December 31, 1997, 1996 and 1995,
respectively. The favorable gross margin trend reflected the increased
utilization of GTS-Hungary's 1,000 VSAT capacity hub located in Budapest. The
Czech Companies had a gross margin of $1.5 million, $0.3 million and $(0.1)
million for the years ended December 31, 1997, 1996 and 1995, respectively. HER
incurred a negative gross margin of $(4.6) million for the year ended December
31, 1997, which was primarily due to the initial cost structure of the new
routes and minimal revenue generated.

    Operating Expenses. Consolidated operating costs were $76.7 million, $52.9
million, and $41.0 million for the years ended December 31, 1997, 1996 and
1995, respectively. The increase in operating costs reflected the growth in
expenditures associated with building business infrastructure for primarily the
TeleRoss Operating Company and GTS-Hungary, the inclusion of HER's operating
expenses in 1997 and increasing corporate staff.

    Equity in (Losses)/Earnings of Ventures. GTS recognized losses from its
investments in non-consolidated ventures of $14.6 million, $10.2 million and
$7.9 million for the years ended December 31, 1997, 1996 and 1995,
respectively. Included in these losses were $3.6 million, $5.7 million and $5.2
million for the years ended December 31, 1997, 1996 and 1995, respectively,
that related to GTS's ownership share of the losses. Also included in the
losses for the year ended December 31, 1997 was a write-off of approximately
$5.4 million which represented the net balance of certain investments in and
advances to ventures in Asia (primarily Beijing Tianmu and V-Tech) and Central
Europe (EuroHivo) that were stated in excess of their net realizable value. The
Company followed the authoritative guidance as prescribed by APB No. 18, "The
Equity Method of Accounting for Investments in Common Stock," for its
determination of the $5.4 million charge. The Company's recoverability analysis
was based on its projected undiscounted cash flows of their equity investees,
since this is the lowest level of cash flow information available. The
underlying reasons for the write-down of the Company's investments were the
result of the problems that are more specifically addressed in "Results of
Operations--Non-Consolidated Ventures (Equity Investees)--Asia,"
"Business--Central Europe" and "Business--Asia." Additionally, included within
GTS's ownership share of the losses incurred and the Excess Losses for the year
ended December 31, 1997 is approximately $14.4 million of losses (of the $14.4
million, approximately $13.5 million related to the write-off of advances to
several Chinese-owned operating telecommunications companies to which the
Company provides technical and financial assistance, and $0.9 million related
to the write-off of inventories, receivables, and other assets) which
represented the Company's share of asset write-offs recorded by certain of the
ventures in Asia (Beijing Tianmu and V-Tech). See "--Results of
Operations--Non-Consolidated Ventures (Equity Investees)--Asia." The Company
would have recognized earnings from its investments in non-consolidated
ventures of $5.2 million for the year ended December 31, 1997, had the Company
not recognized the write-downs of investments and assets of approximately $5.4
million and $14.4 million, respectively. The write-down of Central Europe's
investment in EuroHivo was a result of the Company's decision in the third
quarter to recognize the contingent liabilities associated with the expected
liquidation and discontinuation of EuroHivo's operations as of September 30,
1997. In addition, the Company's results were negatively affected due to the
recognition of Excess Losses of $5.6 million, $4.5 million and $2.7 million for
the years ended December 31, 1997, 1996 and 1995, respectively. See
"--Overview." The Company's losses from its ventures were primarily the result
of most of its ventures being in the early stages of operations. Sovintel and
TCM, however, generated combined earnings of $15.5 million, $11.8 million and
$3.8 million for the years ended December 31, 1997, 1996 and 1995,
respectively, which partially offset losses generated by other ventures.


                                       73
<PAGE>   74


    Other Non-Operating Income. Favorably affecting the 1995 results was the
non-recurring $10.3 million gain that the Company recognized as a result of its
cash settlement of certain claims with a third party in 1995.

    Interest, Net. GTS incurred interest expense of $39.1 million, $11.1
million and $0.7 million for the years ended December 31, 1997, 1996 and 1995,
respectively. Interest expense is comprised of interest incurred from debt
maturing within one year, long-term debt obligations, capital lease
obligations, amortization of debt discount on the long-term debt obligations
and various other debt obligations. The significant increase in interest
expense was due to the $409.8 million increase in debt raised in 1997. See
"--Liquidity and Capital Resources."

    GTS earned interest income of $11.4 million, $3.6 million and $2.2 million
for the years ended December 31, 1997, 1996 and 1995, respectively, primarily
as a result of investing the proceeds from private placements of common stock
in various highly liquid investments.

    Provision for Income Taxes. The Company's consolidated tax provision was
$2.5 million, $1.4 million and $2.6 million for the years ended December 31,
1997, 1996 and 1995, respectively. The Company's financial statements do not
reflect any provision for benefits that might be associated with the U.S. and
non-U.S. loss carryforwards. There can be no assurance that such non-U.S. loss
carryforwards will be allowed, in part or in full, by local tax authorities
against future income.

RESULTS OF OPERATIONS -- NON-CONSOLIDATED VENTURES (EQUITY INVESTEES)

RUSSIA -- CIS

    Sovintel. Sovintel's revenue for the years ended December 31, 1997, 1996
and 1995 was $114.0 million, $75.0 million and $44.3 million, respectively. The
increase in revenue was primarily the result of telecommunications service
revenue, which increased to $85.4 million for the year ended December 31, 1997
from $50.8 million and $26.8 million for the years ended December 31, 1996 and
1995, respectively, due to the Moscow customer base growth and traffic from
other GTS ventures that generated increased volume of outgoing international
and domestic minutes carried by Sovintel. Revenue from incoming international
minutes also increased to $13.1 million for the year ended December 31, 1997,
from $6.8 million and $2.2 million for the years ended December 31, 1996 and
1995, respectively. Included in Sovintel's traffic revenue for 1997 and 1996
was $12.4 million and $5.0 million, respectively, that was related to customers
using phone numbers provided by TCM. This revenue was derived primarily from
international/long distance traffic and local traffic. Sovintel and TCM have an
arrangement whereby Sovintel reimburses TCM 50% of installation charges,
monthly fees and local traffic revenues and approximately 33% of
international/long distance billings from TCM-supplied phone numbers.

    Sovintel's non-traffic-related revenue of $28.6 million, $24.2 million and
$17.5 million for the years ended December 31, 1997, 1996 and 1995,
respectively, was primarily attributable to port sales and monthly port fees
revenues.

    Sovintel's gross margin was $41.3 million, $31.1 million and $18.0 million,
or 36.2%, 41.5% and 40.6% of revenue, for the years ended December 31, 1997,
1996 and 1995, respectively. The decrease in gross margin percentage was
attributable to a general price decrease in international and domestic revenues
due to competitive pressures and a higher percentage of domestic minutes, which
yield a lower margin.

    Operating expenses were $17.0 million, $10.3 million and $7.1 million, or
14.9%, 13.7% and 16.0% of total revenue, for the years ended December 31, 1997,
1996 and 1995, respectively. The increase in operating expenses was related to
increases in turnover taxes associated with revenues and also increased
personnel, advertising and sales force costs required to support Sovintel's
growth.

    Income tax expense was $5.7 million, $5.2 million and $2.6 million for the
years ended December 31, 1997, 1996 and 1995, respectively. The increase in
income tax expense was attributable to Sovintel's profitable operations.

    TCM. TCM's revenue was $29.3 million and $16.5 million for the years ended
December 31, 1997 and 1996, respectively. TCM had minimal activities in 1995.
TCM had a gross margin of $22.1 million and $13.2 million, or 75.4% and 80.0%
of total revenue. The decrease in gross margin as a percentage of revenue was
attributable to higher infrastructure and settlement costs. TCM had operating
expenses of $3.3 million and $1.9 million, or 11.3% and 11.5% of total revenue,
for the years ended December 31, 1997 and 1996, respectively.

    Sovam. Sovam's revenue was $17.8 million, $11.7 million and $4.4 million
for the years ended December 31, 1997, 1996 and 1995, respectively. The
increase in revenues is primarily attributable to the expansion of Sovam's
network throughout Russia and the CIS and the wider variety of service
offerings, including the introduction of Russia On Line services.

    Gross margin was $7.1 million, $3.4 million and $1.5 million, or 39.9%,
29.1% and 34.1% of total revenue for the years ended December 31 in 1997, 1996
and 1995, respectively. Operating expenses were $5.7 million, $5.7 million and
$3.3 million, or 32.0%, 48.7% and 75.0% of total revenue, for the years ended
December 31, 1997, 1996 and 1995, respectively.

    TeleRoss Ventures. Revenue for the TeleRoss Ventures for the years ended
December 31, 1997, 1996 and 1995 was $6.8 million, $2.4 million and $0.2
million, respectively. Revenues resulted from settlement fees charged to
TeleRoss Operating Company. The growth in total revenue was the result of
steady growth in sales of core switched voice services in the five cities
serviced in 1995, an additional seven new cities in the network in 1996 and an
additional city in 1997.

    Gross margin for the years ended December 31, 1997, 1996 and 1995 was $4.7
million, $1.6 million and $0.1 million, respectively. Operating expenses of
$3.6 million, $2.3 million and $0.2 million were incurred for the years ended
December 31, 1997, 1996 and 1995, respectively.

    GTS Cellular. The Company operates three cellular networks through differing
ownership structures: Vostok Mobile, PrimTelefone and Bancomsvyaz.

    Revenue for Vostok Mobile was $25.8 million, $16.5 million and $2.0 million
for the years ended December 31, 1997, 1996 and 1995, respectively. Vostok
Mobile's gross margin was $13.6 million, $9.3 million and $1.1 million, or
52.7%, 56.4% and 55.0% of total revenue, and operating expenses were $10.1
million, $9.2 million and $4.7 million for the years ended December 31, 1997,
1996 and 1995, respectively.

    Revenue for PrimTelefone was $12.1 million, $8.4 million and $2.2 million
for the years ended December 31, 1997, 1996 and 1995, respectively.
PrimTelefone's gross margin was $6.6 million, $4.7 million and $0.6 million, or
54.5%, 56.0% and 27.3% of total revenue, and operating expenses were $3.6
million, $3.7 million and $0.7 million for the years ended December 31, 1997,
1996 and 1995, respectively.

    Bancomsvyaz did not have significant operations until 1997. Revenue for
Bancomsvyaz was $7.2 million and gross margin was $2.8 million, or 38.9% of
total revenue, for the year ended December 31, 1997. Operating expenses were
$4.9 million for the year ended December 31, 1997.

WESTERN EUROPE

    HER. HER earned a small revenue stream in 1996 and no revenue in 1995.
Operating expenses were $16.0 million and $6.7 million for the years ended
December 31, 1996 and 1995, respectively. The increase in selling, general and
administrative expenses reflected HER's continued transition from the start-up
phase to the operational phase. In 1997, HER was included in the consolidated
results of the Company.

    GTS-Monaco Access. Limited international traffic was carried from GTS
subsidiaries through GTS-Monaco Access for termination worldwide during 1995
which resulted in minimal revenues earned. Total revenue was $13.0 million and
$3.9 million and gross margin was $0.2 million and $(0.4) million for the years
ended December 31, 1997 and 1996, respectively.

CENTRAL EUROPE

     EuroHivo. EuroHivo's operating results were minimal for the years ended
December 31, 1997, 1996 and 1995. In September 1997, the Company recorded a
$2.4 million charge to recognize the liabilities associated with the planned
liquidation and discontinuance of EuroHivo's operations. See Footnote 3 in the
Company's audited financial statements for additional disclosures related to
EuroHivo.

ASIA

    Most of the Company's ventures within the Asia region were in the start-up
phase and had not commenced operations in 1996. The non-consolidated ventures
in the Asia region had revenue of $7.0 million for the year ended December 31,
1996, and had minimal revenues in 1997 and 1995. The revenue in 1996 consisted
principally of equipment sales. The Company believes that future revenue will
be derived primarily from providing telecommunications engineering and
consulting services.

    During the year ended December 31, 1997, the V-Tech and Beijing Tianmu
business ventures (the "Asia Ventures") determined that a charge of $14.4
million (GTS's portion) was appropriate as a result of the write-off of $13.5
million of advances to several Chinese-owned operating telecommunications
companies to which the Asia Ventures provide technical and financial assistance
and $0.9 million related to the write-off of inventories, receivables and other
assets. The Asia Ventures followed the authoritative guidance as prescribed by
SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," for their determination of the $13.5
million charge as they believed that the advances, as evidenced by legal
agreements between the Asia Ventures and the underlying operating
telecommunications companies, represents long-lived assets. (The Asia Ventures
would have reflected the same charge had they followed the authoritative
accounting guidance as prescribed by APB No. 18 or SFAS No. 5, "Accounting for
Contingencies.") The Asia Ventures recoverability analysis was based on their
projected undiscounted cash flows of their respective operations since this is
the lowest level of cash flow information available. The underlying reasons for
the write-offs were the result of problems dealing with one of the Asian
partners, the inability of the Chinese operating telecommunications companies
to develop markets for their services, and technical problems, all of which
surfaced during the third quarter of 1997. See Footnote 3 in the Company's
audited financial statements for additional disclosures related to the
Company's Asia operations and "Business--Asia."

LIQUIDITY AND CAPITAL RESOURCES

    The telecommunications business is capital intensive. The Company generally
is the primary source of funding for its ventures, both for working capital and
capital expenditures. Under a typical arrangement, GTS's venture partner
contributes the necessary licenses or permits under which the venture will
conduct its business, office space and other equipment. GTS's contribution is
generally cash and equipment, but may consist of other specific assets as
required by the joint venture agreement.

    The Company has raised capital through the issuance of equity securities
and through various debt agreements. The issuance of equity securities has
raised $36.4 million, $107.7 million, $42.1 million and $62.1 million in 1997,
1996, 1995 and 1994, respectively, net of placement fees, for a total of $248.3
million. In addition, the Company and HER received $409.8 million, $60.0
million and $23.3 million in 1997, 1996 and 1995, respectively, for a total of
$493.1 million under various debt agreements. Included within the debt proceeds
identified above, the Company received $3.5 million, $60.0 million and $10.0
million in 1997, 1996 and 1995, respectively, from lenders who are affiliated
with, and are considered related parties to, the Company as a result of their
(or their affiliates) ownership of the Company's Common Stock.

    The Company had working capital of $285.3 million and $46.9 million as of
December 31, 1997 and 1996, respectively. Approximately $190.5 million of
working capital at December 31, 1997 is intended to be used for the buildout of
the HER Network. The Company had an accumulated deficit of $242.9 million as of
December 31, 1997, including net losses of approximately $117.0 million, $68.0
million and $40.4 million for the years ended 




                                       76

December 31, 1997, 1996 and 1995, respectively. During 1997, the Company has
incurred and expects to continue to incur substantial expenditures to fund the
working capital requirements of its ventures, to provide capital equipment for
certain of its ventures, and to engage in new development and acquisitions.

    GTS will require substantial capital investment to execute its business
plans and to fund expected operating losses. Management expects that GTS and
its ventures will incur over $515.0 million of capital expenditures and
investments in ventures during the next three years, of which approximately
$235.0 million will be incurred in 1998. The Company has obtained funds in 1997
through a variety of financing arrangements, including (i) the issuance in
September 1997 of $39.2 million of Common Stock in a private placement of
equity with a value of $15.67 per common share, (ii) the issuance in August
1997 of $265.0 million in gross proceeds (of which $56.6 million was placed
into escrow to fund the first two years' interest payments) of 11.5% Senior
Notes due in August 2007 by HER that may be redeemed upon the successful
completion of a complying equity offering by HER or meeting other certain
criteria, and (iii) the issuance in July and August 1997 of $144.8 million in
gross proceeds of the Convertible Bonds by GTS that are convertible into Common
Stock upon the Company's completion of a complying equity offering.

    The Company effected a three-for-two split of its common stock effective
December 31, 1997, and the information presented in this "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
reflects that action.

    Subsequent to December 31, 1997, the Company raised approximately $255.3
million in gross proceeds from an initial public stock offering of 12.8 million
common shares at $20.00 per share. Such initial public offering constituted a
"complying public equity offering" under the Company's Convertible Bonds. As a
result, the conversion price of the Bonds is $20 per share. In addition, the
Company issued $105.0 million in gross proceeds of 9.875% senior notes due
February 15, 2005, of which $19.6 million was placed in escrow to fund the
first two years' interest payments. The Company believes that the net proceeds
from these offerings, together with existing cash, will be sufficient to fund
its expected capital needs until at least June 1999. The Company expects that
it may require additional capital to execute its current business plan and to
fund expected operating losses, as well as to consummate future acquisitions
and exploit opportunities to expand and develop its businesses.

    The actual amount and timing of the Company's future capital requirements
may differ materially from management's estimates. In particular, the accuracy
of management's estimates is subject to changes and fluctuations in the
Company's revenues, operating costs and development expenses, which can be
affected by the Company's ability to (i) effectively and efficiently manage the
expansion of the HER network and operations, (ii) obtain infrastructure
contracts, rights-of-way, licenses and other regulatory approvals necessary to
complete and operate the HER network, (iii) negotiate favorable contracts with
suppliers, including large volume discounts on purchases of capital equipment
and (iv) access markets, attract sufficient numbers of customers and provide
and develop services for which customers will subscribe. The Company's revenues
and costs are also dependent upon factors that are not within the Company's
control such as regulatory changes, changes in technology, increased
competition and various factors such as strikes, weather, and performance by
third parties in connection with the Company's operations. Due to the
uncertainty of these factors, actual revenues and costs may vary from expected
amounts, possibly to a material degree, and such variations are likely to
affect the Company's future capital requirements. Historically, GTS has
experienced liquidity problems resulting in part from the Company's need to
meet the capital requirements of certain of its joint ventures in excess of
forecast amounts. In addition, certain of the Company's joint ventures have not
met management's financial performance expectations or have not been able to
secure local country financing and thus have not been able to generate the
expected cash inflows. In addition, if the Company expands its operations at an
accelerated rate or consummates acquisitions, the Company's funding needs will
increase, possibly to a significant degree, and it will expend its capital
resources sooner than currently expected. The Company may also be required to
repay its Convertible Bonds upon maturity in the year 2000 to the extent such
bonds are not converted into Common Stock. As a result of the foregoing, or if
the Company's capital resources otherwise prove to be insufficient, the Company
may need to raise additional capital. See "Business."

    There can be no assurances that the Company will be able to consummate
additional financing on favorable terms. As a result, the Company may be
subject to additional or more restrictive financial covenants, its interest


                                       77

obligations may increase significantly and its existing shareholders may be
adversely diluted. Failure to generate sufficient funds in the future, whether
from operations or by raising additional debt or equity capital, may require
the Company to delay or abandon some or all of its anticipated expenditures, to
sell assets, or both, either of which could have a material adverse effect on
the operations of the Company.

HER

    Construction of the HER fiber optic network is one of the Company's most
significant business activities. The buildout of the network is expected to
require approximately $290.0 million of capital expenditures, with
approximately $35 million required for the initial five country network. See
"Business--Western Europe--HER." As of December 31, 1997, approximately $34.3
million has been spent on network capital expenditure. In August 1997, HER
completed the issuance of $265.0 million in gross proceeds of 11.5% Senior
Notes due in August 2007. The Senior Notes are general unsecured obligations of
HER. HER currently estimates that its capital resources will be sufficient to
fund operations and expected network development through December 1998, at
which time it may be required to obtain additional funds. Sources of capital to
fund network development after 1998 may include internally generated funds,
bank debt and vendor financing. HER is currently in discussions with a number
of financial institutions to obtain debt financing and to negotiate vendor
financing with key suppliers of network equipment. Any failure to obtain
necessary financing may require HER to delay or abandon its plans for deploying
the remainder of the network and would jeopardize the viability of HER, or may
require the Company to make additional capital contributions to HER at the
expense of the Company's other operations, either of which could have a
material adverse effect on the operations of the Company. There can be no
assurance that GTS or its partners in HER would have sufficient capital to make
contributions to HER, or that they would be willing to do so.

    Pursuant to the HER Recapitalization, in 1997, HER offered to GTS-Hermes,
HIT Rail and the eleven individual members of the HIT Rail consortium the right
to subscribe to additional common stock of HER. GTS-Hermes and two of the
members of HIT Rail exercised their rights, while HIT Rail and the nine
remaining members of HIT Rail declined to participate.

    As a result of the finalization of the HER Recapitalization, total
shareholder loans of ECU 39.4 million (approximately $48.5 million) from,
collectively, GTS-Hermes, HIT Rail and two of the members of HIT Rail, were
converted into equity. Additionally, GTS-Hermes contributed ECU 46.0 million
(approximately $51.8 million) and one of the members of HIT Rail contributed a
ten-year fiber optic cable lease which was valued at ECU 1.8 million
(approximately $2.0 million). The ownership of HER subsequent to the HER
Recapitalization was as follows: GTS-Hermes, 79.08%; HIT Rail, 12.63%; and the
two members of HIT Rail combined, 8.29%. See "Business -- Western Europe -- HER
- -- HER Recapitalization." In March 1998, Hit Rail sold a portion of its
ownership interest to GTS-Hermes for ECU 13.5 million (approximately $14.6
million) and, as a result, GTS-Hermes increased its ownership of HER to 89.42%.
See "Business---Western Europe---HER---HER Recapitalization."

LIQUIDITY ANALYSIS

    The Company had cash and cash equivalents of $318.8 million and $57.9
million as of December 31, 1997 and 1996, respectively. Approximately $190.5
million of the $319.0 million of cash and cash equivalents at December 31,
1997, is intended to be used for the build-out of the HER network. The Company
had restricted cash of $66.9 million and $16.2 million as of December 31, 1997
and 1996, respectively. Restricted cash included $29.0 million held in escrow
to pay the first two years' interest payments on the Senior Notes of HER,
amounts held for equipment purchases under various debt agreements, and cash
maintained in foreign financial institutions that may not be readily
convertible into dollars or easily repatriated.

    During the years ended December 31, 1997 and 1996, the Company used $48.6
million and $39.0 million, respectively, of cash for operating activities. Cash
used for investing activities was $103.4 million and $80.9 million for the
years ended December 31, 1997 and 1996, respectively. The use of cash in
operations and for investing activities reflected primarily the development and
buildout of existing telecommunications networks and the funding of fully
operational ventures. There can be no assurance that the Company's operations
will achieve or sustain profitability or positive cash flow in the future. If
the Company cannot achieve and sustain operating 






                                       78
<PAGE>   79

profitability or positive cash flow from operations, it may not be able to meet
its debt service obligations or working capital requirements.

    Substantially all of the Company's operations are in foreign countries and
therefore the Company's consolidated financial results are subject to
fluctuations in currency exchange rates. The Company's consolidated operations
transact their business in the following significant currencies: Russian Ruble,
Hungarian Florint, Belgium Franc and the European Currency Equivalent. For
those operating companies that transact their business in currencies that are
not readily convertible, the Company attempts to minimize its exposure by
indexing its invoices and collections to the applicable dollar/foreign currency
exchange rate to the extent its costs (including interest expense, capital
expenditures and equity) are incurred in U.S. dollars. Although the Company is
attempting to match revenues, costs, borrowing and repayments in terms of their
respective currencies, the Company may experience economic loss and a negative
impact on earnings with respect to holdings solely as a result of foreign
currency exchange rate fluctuations, which include foreign currency
devaluations against the U.S. dollar. Furthermore, certain of the Company's
operations have notes payable and notes receivable which are denominated in a
currency other than their own functional currency or loans linked to the U.S.
dollar. The Company may also experience economic loss and a negative impact on
earnings related to these monetary assets and liabilities. See
"Business--Russia and the CIS--Certain Considerations Applicable to the
Company's Operations in Russia and the CIS--Exchange Controls and Risks
Relating to Russian Securities" and "Business--Certain Considerations Generally
Applicable to the Company's Operations--Currency and Exchange Risks."

    The Company has developed risk management policies that establish
guidelines for managing foreign exchange risk. The Company is currently
evaluating the materiality of foreign exchange exposures in different countries
and the financial instruments available to mitigate this exposure. The
Company's ability to hedge its exposure is limited since certain of its
operations are located in countries whose currencies are not easily
convertible. Financial hedge instruments for these countries are nonexistent or
limited and also pricing of these instruments is often volatile and not always
efficient. The Company is designing reporting processes to monitor the
potential exposure on an ongoing basis and expects to implement this process
before the end of 1998. The Company will use the output of this process to
execute financial hedges to cover foreign exchange exposure when practical and
economically justified.

    The Company is considering alternatives to hedge the foreign exchange
exposure resulting from the issuance of $265 million senior notes by HER. It
expects to have a transaction which eliminates this risk consummated by the end
of April 1998.

YEAR 2000 COMPLIANCE

    The Company is currently in the process of assessing its year 2000
compliance costs and of converting its computer systems to year 2000 compliant
software. This process includes obtaining confirmations from the Company's
primary vendors that plans are being developed or are already in place to
address processing of transactions in the year 2000. The Company does not
expect that the cost of converting such systems will be material to its
financial condition or results of operations. The Company currently believes it
will be able to achieve year 2000 compliance by the end of 1999, and currently
does not anticipate any material disruption in its operations as the result of
any failure by the Company to be in compliance or that year 2000 compliance
costs will have a material effect on the Company's earnings.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS







         The Board of Directors
         Global TeleSystems Group, Inc.

                  We have audited the accompanying consolidated balance sheets
         of Global TeleSystems Group, Inc. as of December 31, 1996 and 1997, and
         the related consolidated statements of operations, cash flows, and
         shareholders' equity for each of the three years in the period ended
         December 31, 1997. Our audits also included the financial statement
         schedules listed in the Index at Item 14(a). These financial statements
         and schedules are the responsibility of the Company's management. Our
         responsibility is to express an opinion on these financial statements
         and schedules based on our audits.

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

                  In our opinion, the financial statements referred to above
         present fairly, in all material respects, the consolidated financial
         position of Global TeleSystems Group, Inc. at December 31, 1996 and
         1997, and the consolidated results of its operations and its cash flows
         for each of the three years in the period ended December 31, 1997, in
         conformity with generally accepted accounting principles. Also, in our
         opinion, the related financial statement schedules, when considered in
         relation to the basic financial statements taken as a whole, present
         fairly in all material respects the information set forth therein.

GLOBAL TELESYSTEMS GROUP, INC.
Notes to Consolidated Financial Statements


NOTE 1:        NATURE OF BUSINESS OPERATIONS

Global TeleSystems Group, Inc. ("GTS" or "the Company"), is a provider of a
broad range of telecommunications services to businesses, other
telecommunications service providers and consumers through its operation of
voice and data networks, international gateways, local access and cellular
networks and the provision of various value-added services in the Commonwealth
of Independent States ("CIS"), primarily Russia, Central Europe, and India and
China ("Asia"). The Company, through two of its ventures, is also building a new
infrastructure for transporting international voice, data and video traffic for
other carriers throughout Western Europe and for worldwide international voice,
data and video traffic that either originates or terminates in, or transits
through, Western Europe. See further discussion of the Company's business
operations within Note 3, "Investments In and Advances to Ventures," and Note
14, "Segment Information and Certain Geographical Data."

Certain of the Company's ventures are in the early stages of operations in the
telecommunications industry. The Company's businesses are developing rapidly;
some are in countries with an emerging economy, which by nature have an
uncertain economic, political and regulatory environment. The general risks of
operating businesses in the CIS and other developing countries include the
possibility for rapid change in government policies, economic conditions, the
tax regime and foreign currency regulations.

The ultimate recoverability of the Company's investments in and advances to
ventures is dependent on many factors including, but not limited to, the
economies of the countries in which it does business; the ability of the Company
to maintain the necessary telecommunications licenses; and the ability of the
Company to obtain sufficient financing to continue to meet its capital and
operational commitments.

On December 1, 1997, the Company filed an amendment to its Certificate of
Incorporation to effect an increase in the authorized common shares from
60,000,000 to 135,000,000; a 3 for 2 common share stock split, 1 1/2 common
shares for every common share issued and outstanding; and an increase in the par
value of its authorized common shares from $0.0001 to $0.10 on a post-split
basis. Accordingly, the Company has presented share and per share data for
issued and outstanding shares as well as options and warrants on a restated
basis to give effect to the increase in authorized common shares, the stock
split and the increase in par value for its capital stock.

Subsequent to year end, the Company completed an initial public offering of 12.8
million shares of common stock at $20 per common share (the "Stock Offering").
The Company also issued aggregate principal amount $105.0 million of 9.875%
senior notes due 2005 (the "Notes Offering" and together with the Stock
Offering, the "Offerings"). See Note 15, "Subsequent Events."



NOTE 2:        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

Wholly-owned subsidiaries and majority-owned ventures where the Company has
unilateral operating and financial control are consolidated. Those ventures
where the Company exercises significant influence, but does not exercise
unilateral operating and financial control are accounted for by the equity
method. The Company has certain majority-owned ventures that are accounted for
by the equity method as a result of minority shareholder rights, super majority
voting conditions or other governmentally imposed uncertainties so severe that
they prevent the Company from obtaining unilateral control of the venture. If
the Company has little ability to exercise significant influence over a venture,
the venture is accounted for by the cost method. All significant intercompany
accounts and transactions are eliminated upon consolidation.

GLOBAL TELESYSTEMS GROUP, INC.
Notes to Consolidated Financial Statements

NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The Company recognizes profits and losses in accordance with its underlying
ownership percentage or allocation percentage as specified in the agreements
with its partners; however, the Company recognizes 100% of the losses in
ventures where the Company bears all of the financial risk. When such ventures
become profitable, the Company recognizes 100% of the profits until such time as
the excess losses previously recognized have been recovered.

RECLASSIFICATIONS

Certain reclassifications have been made to the 1995 and 1996 consolidated
financial statements in order to conform to the 1997 presentation.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less at the time of purchase to be cash equivalents. The Company had
$16.2 million and $66.9 million of restricted cash at December 31, 1996 and
1997, respectively. The restricted cash is primarily related to cash held in
escrow for interest payments associated with the Company's debt obligations.

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 telecommunications equipment and three to five years for
furniture, fixtures and equipment and other property, or their contractual term.
Construction in process reflects amounts incurred for the configuration and
build-out of telecommunications equipment and telecommunications equipment not
yet 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 intends to capitalize material
interest costs associated with the construction of capital assets for business
operations and amortize the costs over the assets' useful lives. The Company has
not capitalized any interest costs through December 31, 1997.

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 their estimated useful lives ranging from three to ten
years. Intangible assets, principally telecommunications service contracts,
licenses and deferred financing costs, are amortized on a straight-line basis
over the lesser of their estimated useful lives, generally three to fifteen
years, or their contractual term. In accordance with Accounting Principles Board
("APB") Opinion No. 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 intangible assets.

LONG-LIVED ASSETS

In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of," 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

<PAGE>   88
GLOBAL TELESYSTEMS GROUP, INC.
Notes to Consolidated Financial Statements

NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 flows 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. During the year ended December 31, 1996, the Company's analyses
indicated that there was not an impairment of its long-lived assets. During the
year ended December 31, 1997, the Company's analyses indicated that there was an
impairment of its long-lived assets. Accordingly, the Company recorded a
write-down of long-lived assets associated with its investments in the Asia and
Central Europe regions (see Note 3, "Investments in and Advances to Ventures").

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. The Company does not provide for deferred taxes on the undistributed
earnings of its foreign companies, as such earnings are intended to be
permanently reinvested in those operations.

FOREIGN CURRENCY TRANSLATION

The Company follows a translation policy in accordance with SFAS No. 52,
"Foreign Currency Translation." In most instances, the local currency is
considered the functional currency for the Company's subsidiaries and ventures,
except for operations in the CIS, where the U.S. dollar has been designated as
the functional currency. Assets and liabilities of these subsidiaries and
ventures 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 the cumulative translation
adjustment, a separate component of shareholders' equity. Gains and losses from
foreign currency transactions of these subsidiaries and ventures are included in
the operations of the subsidiary or venture.

For those ventures operating in the CIS, the temporal method for translating
assets and liabilities is used. Accordingly, monetary assets and liabilities are
translated at current exchange rates while non-monetary assets and liabilities
are translated at their historical rates. Income and expense accounts are
translated at average monthly rates of exchange. The resultant translation
adjustments are included in the operations of the subsidiaries and ventures.

REVENUE RECOGNITION

The Company records as revenue the amount of telecommunications services
rendered, as measured primarily by the minutes of traffic processed, after
deducting an estimate of the traffic that will be neither billed nor collected.
Revenue from service or consulting contracts is accounted for when the services
are provided. Equipment sales revenue is generally recognized upon shipment of
the equipment. Billings received in advance of service being performed are
deferred and recognized as revenue as the service is performed.

NET LOSS PER SHARE

During 1997, the Company adopted SFAS No. 128, "Earnings Per Share," which
requires the Company to present basic and fully diluted earnings per share for
all years presented. The Company's net loss per share calculation (basic and
fully diluted) is based upon the weighted average common shares issued. There
are no reconciling items in the numerator or denominator of the Company's net
loss per share calculation. Employee stock options,



                                       88
<PAGE>   89
GLOBAL TELESYSTEMS GROUP, INC.
Notes to Consolidated Financial Statements


NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

warrants, and convertible debt instruments have been excluded from the net loss
per share calculation because their effect would be anti-dilutive (see Note 5,
"Debt Obligations," Note 6, Shareholders' Equity and Note 7, "Stock Option
Plans").

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company believes that the carrying amount of its financial instruments
reported in the balance sheets approximates their fair value.

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 and
notes receivable. The Company maintains most of its cash and cash equivalents in
one high-quality U.S. financial institution. 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. The
Company provides allowances for potential credit losses when necessary.

The Company does not currently hedge against foreign currency fluctuations,
although the Company may implement such practices in the future. Under current
practices, the Company's results of operations could be adversely affected by
fluctuations in foreign currency exchange rates.

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.

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board has issued two new standards which
become effective for reporting periods beginning after December 15, 1997. SFAS
No. 130, "Reporting Comprehensive Income," requires additional disclosures with
respect to certain changes in assets and liabilities that previously were not
required to be reported as results of operations for the period. The Company
will begin making the additional disclosures required by SFAS No. 130 in the
first quarter of 1998. SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," requires financial and descriptive
information with respect to "operating segments" of an entity based on the way
management disaggregates the entity for making internal operating decisions. The
Company will begin making the disclosures required by SFAS No. 131 with
financial statements for the period ending December 31, 1998.

NOTE 3:       INVESTMENTS IN AND ADVANCES TO VENTURES

The Company has various investments in ventures that are accounted for by the
equity method. The Company's ownership percentages in its equity method
investments range from 49% to 80%. The Company has no investments in ventures
that are accounted for by the cost method.

The components of the Company's investments in and advances to ventures are as
follows:

</TABLE>

In applying the equity method of accounting, the Company's policy is to amortize
the excess of investment cost over equity in net assets acquired based upon an
assignment of the excess to the fair value of the venture's identifiable
tangible and intangible assets, with any unassigned amounts designated as
goodwill. The Company then amortizes the allocated costs in accordance with its
policies defined in Note 2, "Summary of Significant Accounting Policies."

The Company has financed the operating and investing cash flow requirements of
several of its ventures in the form of cash advances. The Company anticipates
that these ventures will generate sufficient cash inflows for the repayment of
the cash advances as their businesses mature. Also, due to the long-term nature
of the anticipated repayment period and the potential risk associated with the
repatriation of the cash advances, the Company has aggregated its investments in
and cash advances to the ventures.

The Company's share of the ventures' foreign currency translation adjustments is
reflected in the investment accounts.

INVESTMENT RECOVERABILITY

The Company periodically evaluates the recoverability of its equity investments,
in accordance with APB No. 18, "The Equity Method of Accounting for Investments
in Common Stock," and if circumstances arise where a loss in value is considered
to be other than temporary, the Company will record a write-down of excess
investment cost. The Company's recoverability analysis is based on the projected
undiscounted cash flows of the operating ventures, which is the lowest level of
cash flow information available. As of December 31, 1997, the Company recorded a
write-off of approximately $5.4 million, which represented the net balance of
certain investments in and advances to ventures located in Asia (primarily
Beijing Tianmu and V-Tech) and Central Europe (Eurohivo) which were stated in
excess of their net realizable value. The entire net balance of these
investments in and advances to ventures was written-off based on the fact that
these ventures project overall negative cash flows for the foreseeable future.
The ventures projected future operations deteriorated during 1997 as a result of
problems

</TABLE>

Prior to the write-off detailed above, the Company included approximately $14.4
million in its accumulated losses (of the $14.4 million, approximately $13.5
million related to the write-off of advances to several Chinese owned operating
telecommunications companies to which the Company provides technical and
financial assistance and $0.9 million related to the write-off of inventories,
receivables, and other assets) which represented the Company's share of asset
write-offs recorded by certain of the Company's equity method investments in
Asia during the year ended December 31, 1997. Such write-offs, for the same
reasons mentioned in the previous paragraph, were recorded by the Company's
equity method investments pursuant to SFAS No. 121 and are included in the
$(23.3) million accumulated (losses) detailed above. Additionally, during the
year ended December 31, 1997 the Company recorded a charge of $1.7 million in
order to write off certain holding company assets associated with the ventures
located in Asia and Central Europe. This charge has been included as a separate
line item in the Company's statement of operations.

HERMES EUROPE RAILTEL B.V. ("HER") RECAPITALIZATION

During the year ended December 31, 1997, HER recapitalized its equity structure
and amended its existing shareholder agreement. In connection with the HER
recapitalization the Company contributed approximately $51.8 million and
converted existing note receivables of approximately $28.4 million in exchange
for an additional 29% equity interest in HER. As a result of the
recapitalization and amended shareholder agreement, the Company obtained
unilateral control over HER. As such, HER has been consolidated into the
Company's financial statements effective July 6, 1997, the effective date of the
recapitalization. The Company recognized approximately $8.7 million of goodwill
in connection with the recapitalization. As a result of the Company's loss
recognition policy, the consolidation of HER would not have a material impact on
the Company's historical financial position or operating results and thus no pro
forma information is disclosed herein.

As of December 31, 1997, the consolidation of HER resulted in reductions of
$72.9 million, $10.0 million, and $4.6 million in the equity in net assets
acquired, excess of investment cost over equity in net assets acquired, and cash
advances and other, respectively. Additionally, as of December 31, 1997 the
consolidation of HER had a $21.4 million favorable impact on the accumulated
(losses) earnings recognized.

NOTE 5:  DEBT OBLIGATIONS (CONTINUED)

In the third quarter of 1997, HER issued $265.0 million aggregate principal
amount of senior notes due August 15, 2007 (the "Senior Notes"). The Senior
Notes are general unsecured obligations of the subsidiary with interest payable
semiannually at a rate of 11.5%. Approximately $56.6 million of the net proceeds
of the offering of the Senior Notes is being held in escrow for the first four
semiannual interest payments commencing in 1998. HER may redeem the Senior
Notes, in whole or in part, any time on or after August 15, 2002 at specific
redemption prices. HER may also redeem a portion of the Senior Notes 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 of HER with gross proceeds of at least $75
million or in certain other circumstances specified in the indenture for the
Senior Notes, provided, however, that at least two-thirds of the principal
amount of the Senior Notes originally issued remain outstanding after each such
redemption.

In July 1997, the Company issued $144.8 million aggregate principal amount of
senior subordinated convertible bonds (the "Bonds") due June 30, 2000. The Bonds
constitute direct, unsecured senior subordinated indebtedness after existing
debt of $82.7 million. Upon completion of a complying public equity offering as
defined in the Bond agreement (an "Offering") or in certain other circumstances
as defined in the Bond agreement, the Bonds may be converted at the option of
the holders from time to time, in whole or in part, prior to the close of
business on June 30, 2000, into shares of the Company's common stock, par value
$0.10 per share. The Bonds will be convertible into such number of shares of the
Company's common stock as is equal to the principal amount of such Bonds divided
by the applicable conversion price as defined in the Bond Agreement. The Bonds
bear interest payable semiannually at a stated rate of 8.75% for the first year,
9.25% for the second year and 9.75% for the final year. In the event of an
Offering, the interest rate will remain at the interest rate prevailing at the
time of the Offering until maturity. In the event that an Offering has not
occurred by the maturity date, the Bonds will be redeemed at 121% of their
principal amount. As a result of the redemption feature, interest expense is
being accrued and accreted at a 15% annual rate. (Subsequent to year end, the
Company completed the Stock Offering at $20.00 per common share which will
result in the Bonds being convertible into approximately 7.2 million shares of
the Company's common stock. In addition, due to the completion of the Stock
Offering, the interest rate will remain at 8.75% until maturity (see Note 15,
"Subsequent Events").)

In 1996, the Company entered into long-term obligations ("Debt Obligations"),
totaling $70.0 million, with lenders (the "Lenders"). The Lenders are affiliated
with and are considered related parties to the Company, as a result of their
ownership of the Company's common stock (see Note 12, "Related Party
Transactions"). The Debt Obligations require principal payments beginning in the
third year, to maturity in the fifth year. The Debt Obligations bear an interest
rate of 10.0% and require interest payments beginning in the first fiscal
quarter subsequent to the date of issuance. At the Company's discretion, the
initial interest accrued until the first principal payment can be deferred until
maturity. Upon commencement of principal payments, the Company is obligated to
make concurrent interest payments. Further, in connection with the Debt
Obligations, the Company issued warrants to purchase 7,777,776 common shares,
valued at $20.7 million. In accordance with the terms of the warrant agreement,
the exercise price of the warrants was reduced from $10.27 per share to $9.33
per share, as the outstanding debt had not been repaid prior to December 31,
1996. The warrants may be exercised up to six years after the date of the
relevant agreements. The Company is subject to certain restrictive covenants
pursuant to these Debt Obligations, including restrictions on the payment of
dividends and indebtedness to affiliated ventures. As of December 31, 1997, the
Debt Obligations have been classified within "Related party long-term debt, less
current portion" on the balance sheet. Subsequent to year end the Company repaid
the Debt Obligations by using a portion of the proceeds from the Offerings (see
Note 15, "Subsequent Events").

Certain of the Company's consolidated ventures maintain credit facilities for
their local operations. Borrowings under such credit facilities bear interest at
prevailing negotiated market rates.

Aggregate maturities of long-term debt, as of December 31, 1997, are as follows:
1998 - $12.1 million, 1999 - $1.1 million, 2000 - $149.4 million, 2001 - $0.2
million and $349.5 million thereafter.

NOTE 5:  DEBT OBLIGATIONS (CONTINUED)

The Company paid interest of $0.7 million, $0.2 million and $2.0 million in
1995, 1996 and 1997, respectively. The Company incurred interest expense of
$39.1 million in 1997 and would have recorded $33.1 million in additional
interest expense in 1997 had the Senior Notes and Bonds been outstanding on
January 1, 1997.

During 1995, the Company issued 400,000 shares of common stock to an independent
third party in connection with the purchase of an interest in a venture within
the CIS region. At the discretion of the holder of these shares, the Company is
obligated to repurchase these shares at the prevailing fair market value of the
Company's common stock on the date of repurchase. During 1995, the Company
repurchased 75,000 shares at $10.00 per share and the repurchased shares became
treasury stock. In March 1997, the Company repurchased 32,500 shares at $13.33
per share, and these shares became treasury stock. The Company will be required
to repurchase the remaining shares over the next three years. During 1997, the
Company issued 504,600 shares of common stock pursuant to a purchase agreement
with a seller for a portion of their interest in a venture within the CIS
region. Pursuant to the purchase agreement, the Company is obligated to assist
the seller in locating a purchaser for the common stock, and if unable to do so,
to repurchase the issued common stock. The Company has accreted the value of the
outstanding common stock subject to repurchase (325,000 shares at December 31,
1996 and 797,100 shares at December 31, 1997), to the fair value of the
Company's common stock as of December 31, 1996 and 1997 ($13.33 and $15.67 per
share, respectively).

During 1996, the Company entered into the Debt Obligations totaling $70.0
million with the Lenders. In connection with the Debt Obligations, the Company
issued warrants to purchase 7,777,776 common shares at $10.27 per share. The
exercise price of the warrants was automatically reduced to $9.33 per share as
of December 31, 1996, because the Debt Obligations remained outstanding. The
warrants expire during the first and second quarters of 2002.

The Company does not intend to pay dividends on common stock in the foreseeable
future. In addition, certain of the Company's financing agreements include
covenant restrictions precluding the payment of dividends by the Company.

The Company has reserved 15,572,260 shares of common stock for issuance upon
conversion of the exercise of outstanding and future stock options, warrants and
similar rights.

PREFERRED STOCK

As of December 31, 1996 and 1997, there were 10,000,000 shares of $0.0001 par
value preferred stock authorized, with rights and preferences to be determined
by the Board of Directors. As of December 31, 1996 and 1997, no shares of
preferred stock had been issued.

NOTE 7:  STOCK OPTION PLANS

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
loss for the years ended December 31, 1995, 1996 and 1997 would have been
approximately $40.9 million, $69.4 million and $123.4 million, respectively. The
fair value of options granted during 1995 and 1996 are estimated as $2.19 and
$2.93 per common share, respectively, on the date of grant using the minimum
value option pricing model with the following assumptions: dividend yield 0%,
risk free interest rate of 5.50% for 1995 and 6.13% for 1996, and an expected
life of five years. The fair value of options granted during 1997 are estimated
as $7.35 per common share, on the date of grant using the Black Scholes option
valuation model with the following assumptions: dividend yield 0%, risk free
interest rate of 5.74%, an expected life of five years, and an expected
volatility of .50. The Company determined its volatility factor with the
assistance of an investment banker, based on peer group public companies.

The Company maintains the 1992 Stock Option Plan, the Non-Employee Directors
Stock Option Plan and the GTS Equity Compensation Plan (the "Option Plans"). As
of December 31, 1997, the maximum number of shares of common stock available for
grant under the Option Plans was 8,836,534. All options granted under the Option
Plans are 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
Option Plans 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

NOTE 7:  STOCK OPTION PLANS (CONTINUED)

In addition, prior to the establishment of the Option Plans, certain options
were granted in 1991 to certain key employees and former employees to purchase
1,172,250 shares of the Company's common stock at an exercise price of $0.53 per
share. All options were granted at an exercise price equal to the fair value of
the underlying common stock at the date of grant. The options vested in equal
increments over a three-year period. During 1993, 603,000 of the options were
canceled and in 1994, 50,250 options were exercised, leaving 519,000 fully
vested options outstanding at December 31, 1995, 1996 and 1997.

During 1996, the Company implemented the GTS 1996 Top Talent Retention Program
(the "Program"), which granted options to certain employees under the 1992 Stock
Option Plan. The Program was offered to 28 employees, who had an aggregate of
339,524 options, and provided for an altered vesting period based on certain
revenue levels achieved and certain stock price levels maintained. If these
performance-based achievements are not attained, the options vest in April 2001.
As of December 31, 1997 no performance levels were met.

In the fourth quarter of 1997, HER implemented a stock option plan for its key
officers and employees (the "HER Plan"). The ownership dilution caused by the
HER Plan is not expected to be significant. As a result of issuing options under
the HER Plan, HER will incur a non-cash charge of approximately $3.7 million, of
which $2.6 million was recorded during the fourth quarter and the remaining $1.1
million will be recognized in 1998.

NOTE 8:        EMPLOYEE BENEFIT PLAN

The Company has a 401(k) retirement savings plan (the "Savings Plan") covering
all U.S. citizen employees. The Savings Plan qualifies under section 401(k) of
the Internal Revenue Code and as such, participants may defer pretax income in
accordance with federal income tax limitations. The Company provides a 50%
matching contribution on the first 5% contributed by the employee. The Company
may also, at its discretion, make non-matching contributions. Both matching and
non-matching contributions by the Company vest 100% after three years of
service. The Company's expense under the Savings Plan was approximately $0.1
million, $0.2 million and $0.2 million for the years ended December 31, 1995,
1996 and 1997, respectively. The Company made no discretionary (non-matching)
contributions for the years ended December 31, 1995, 1996 or 1997.

HER established a pension plan in 1995 that covers all HER employees upon
twenty-five years of age and at least one year of service. HER has entered into
an insurance arrangement (an annuity contract) whereby an insurance provider has
undertaken a legal obligation to provide specific benefits to participants in
return for a fixed premium. As such, HER does not bear significant financial
risk for its pension plan. HER's expense under the pension plan was $0.05
million, $0.4 million and $0.7 million for the years ended December 31, 1995,
1996 and 1997, respectively.

NOTE 9:        OTHER NON-OPERATING INCOME

Favorably affecting the 1995 results was the non-recurring $10.3 million gain
the Company recognized as a result of its cash settlement of certain claims with
a third party in 1995.

As of December 31, 1997, the Company had net operating loss carryforwards for
U.S. federal income tax purposes of approximately $110 million expiring in
fiscal years 2003 through 2012. Because of the "change in ownership" provisions
of the Tax Reform Act of 1986, the utilization of the Company's net operating
loss carry-forwards will be subject to an annual limitation.

Notes to Consolidated Financial Statements




NOTE 10:  INCOME TAXES (CONTINUED)

The Company's investment in EDN Sovintel is treated for U.S. tax purposes as a
partnership and, therefore, the Company's share of EDN Sovintel's income or loss
flows through to the Company's consolidated federal income tax return on a
current basis. Undistributed earnings of the Company's other foreign investments
are considered to be indefinitely reinvested and, accordingly, no provision for
U.S. federal and state income taxes, or foreign withholding taxes has been made.
Upon distribution of those earnings, the Company would be subject to foreign
withholding taxes and U.S. income taxes (subject to reduction for foreign tax
credits).

Certain of the Company's foreign ventures have foreign tax loss carryforwards in
excess of $60 million. The Company's financial statements do not reflect any
provision for benefits that might be associated with such loss carryforwards.

NOTE 11:  COMMITMENTS AND CONTINGENCIES (CONTINUED)

OTHER COMMITMENTS AND CONTINGENCIES

In September 1997, the Company purchased the remaining interest in one of its
subsidiaries, which owns interests in cellular ventures within the CIS region,
for $5.2 million, which was paid in October 1997. Furthermore, the Company is
required to pay additional consideration of a minimum of $2.4 million when
certain revenue levels are met, certain other events occur or, if neither has
occurred, on April 1, 1999. The purchase price and consideration have been
allocated to net assets based on the fair value at the date of acquisition. The
excess of the purchase price over the fair value of the net assets acquired was
$5.9 million, which has been recorded as goodwill and is being amortized on a
straight-line basis over five years.

The Company's consolidated and non-consolidated ventures have future purchase
commitments amounting to $2.7 million and $1.1 million, respectively, as of
December 31, 1997.

In the ordinary course of business, the Company has issued financial guarantees
on debt and equities for the benefit of certain of its non-consolidated
ventures. The total amount guaranteed at December 31, 1997 was approximately
$29.0 million.

MAJOR CUSTOMERS

In 1995, the Company had one major customer, a foreign governmental agency in
Central Europe, representing $2.7 million, or 32.1%, of total revenue. In 1996,
the Company had two major customers, a foreign governmental agency in Central
Europe and a customer in the CIS, representing $3.8 million, or 15.8%, of total
revenue and $2.6 million, or 10.8%, of total revenue, respectively. There were
no major customers in 1997.

TAX MATTERS

The taxation system in Russia ("Russian Taxes") is evolving as the central
government transforms itself from a command to a market oriented economy. The
Russian Federation has introduced and continues to introduce new tax and royalty
laws and related regulations. These laws and regulations are not always clearly
written and their interpretation is subject to the opinions of the local tax
inspectors, Central Bank officials and the Ministry of Finance. Instances of
inconsistent opinions between local, regional and federal tax authorities and
between the Central Bank and Ministry of Finance are not unusual.

The Company's policy is to accrue for contingencies in the accounting period in
which a liability is deemed probable and the amount is reasonably determinable.
In this regard, because of the uncertainties associated with the Russian Taxes,
the Company's Russian Taxes may be in excess of the estimated amount expensed to
date and accrued at December 31, 1996 and 1997. It is the opinion of management
that the ultimate resolution of the Company's Russian Tax liability, to the
extent not previously provided for, will not have a material effect on the
financial condition of the Company. However, depending on the amount and timing
of an unfavorable resolution of this contingency, it is possible that the
Company's future results of operations or cash flows could be materially
affected in a particular period.

In various foreign jurisdictions, the Company is obligated to pay value added
taxes ("VAT") on the purchase or importation of assets, and for certain other
transactions. In many instances, VAT can be offset against VAT the Company
collects and otherwise would remit to the tax authorities, or may be refundable.
Because the law in some jurisdictions is unclear, the local tax authorities
could assert that the Company is obligated to pay additional amounts of VAT. In
the opinion of management, any additional VAT the Company may be obligated to
pay would not be material.

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
developing markets and evolving fiscal and regulatory environments in which the
Company operates. In the opinion of management, the Company's liability, if any,
in all pending litigation, 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 12:  RELATED PARTY TRANSACTIONS

As discussed within Note 5, "Debt Obligations," the Company entered into the
Debt Obligations during 1996 with the Lenders. The Lenders are shareholders of
the Company. As part of these transactions, the Company provided one of the
Lenders with the opportunity, at its discretion, to co-invest with the Company
in all of the Company's new ventures within the Asia region. The Company repaid
the Debt Obligations subsequent to year end (see Note 15, "Subsequent Events").

During 1996 and 1997, the Company, in connection with a venture investment,
entered into two financing agreements with a shareholder of the Company for a
total of approximately $8.6 million. Subject to certain conditions, the
shareholder has the right to require the repayment of this amount in cash or
713,311 shares of the Company's common stock. Subsequent to the Stock Offering,
repayment of this financing must be in exchange for the Company's common stock.
This amount has been included in "Other financing agreements" (see Note 5, "Debt
Obligations").

During 1997, the Company issued 504,600 shares of common stock pursuant to a
purchase agreement with a seller for a portion of their interest in a venture
within the CIS region. As a result of the issuance of the common shares, the
seller became a shareholder of the Company (see Note 3, "Investments in and
Advances to Ventures," and Note 6, "Shareholders' Equity").

The Company has entered into certain consulting agreements with directors of the
Company and paid $0.2 million, $0.2 million and $0.4 million in 1995, 1996, and
1997, respectively, pursuant to those agreements.

The Company had notes receivable due from employees aggregating $0.1 million and
less than $0.1 million as of December 31, 1996 and 1997, respectively, with no
single amount due from any individual in excess of $0.1 million.

The Company derived revenue from affiliates of $3.3 million and $4.4 million in
1996 and 1997, respectively. There was no significant revenue earned from
affiliate sales in 1995.

NOTE 15:  SUBSEQUENT EVENTS

THE OFFERINGS

In February 1998, the Company completed the Stock Offering in which the Company
raised $255.3 million in gross proceeds, including $33.3 million attributable to
the sale of shares resulting from the exercise by the underwriters of an
over-allotment option, from the sale of 12.8 million shares of common stock at
an issue price of $20.00 per share. The Stock Offering resulted in the Company's
common stock being listed in the United States on the National Association of
Securities Dealers Automated Quotation Market and internationally on the
European Association of Securities Dealers Automated Quotation Market. Also in
February 1998, the Company completed the Notes Offering and issued $105.0
million aggregate principal amount of senior notes, due February 15, 2005.
Interest at 9.875% on the Notes will be payable in cash semiannually on February
15 and August 15 of each year, commencing August 15, 1998. Net proceeds from the
Offerings were approximately $336.7 million. Approximately $19.6 million of the
net proceeds of the Notes Offering is being held in escrow for the first four
semiannual interest payments commencing in 1998. Approximately $85.2 million of
the net proceeds of the Offerings has been used to repay the related party Debt
Obligations (see Note 5, "Debt Obligations") of $70.0 million plus accrued
interest that were due March 31, 2001. In addition, approximately $13.2 million
in unamortized discount and debt issuance costs on the Debt Obligations was
written off at the time of repayment. The remaining net proceeds from the
Offerings will primarily be used to provide working capital for existing
ventures, particularly in Russia and the CIS, to expand the Company's operations
and for general corporate purposes, including strategic acquisitions.

As a result of the completion of the Stock Offering, the interest rate for the
Bonds will remain at 8.75% until maturity (see Note 5, "Debt Obligations") and
the 6.25% additional interest that was previously accrued, $4.2 million, has
been reflected as an increase to additional paid-in capital. The Bonds are
convertible into approximately 7.2 million common shares at a conversion price
of $20.00 per share.

The following unaudited pro forma condensed balance sheet and results of
operations of the Company give effect to the Offerings as though the
transactions had occurred on December 31, 1997. The pro forma shares and per
share data have been calculated assuming the Stock Offering occurred on January
1, 1997. The pro forma results are presented for informational purposes only and
do not purport to be indicative of the results of operations which actually
would have been obtained if the transactions had occurred in such periods, or
which may exist or be obtained in the future.

OTHER SUBSEQUENT EVENT TRANSACTIONS

Pursuant to a purchase agreement that the Company has with a venture's partner
in the CIS region (see Note 3, "Investments in and Advances to Ventures," Note
6, "Shareholders' Equity," and Note 12, "Related Party Transactions") the
Company is obligated to pay additional consideration, via shares of common
stock, based on the subsidiary's earnings performance. Based on the 1997
results, the Company is obligated to issue 336,630 shares of common stock during
the first quarter of 1998.

Subsequent to December 31, 1997, HER entered into contractual commitments to
lease fiber pairs, including facilities and maintenance and utilizing the
partial routes for laying fiber optic cable. Based on the contract provisions,
these commitments are currently estimated to aggregate approximately $12.9
million. The commitments have expected lease terms of ten to twenty-one years
with options for renewal rights of one and one-half to five additional years.

The Company entered into a rights agreement (the "Rights Agreement") on February
2, 1998, and accordingly, the Company authorized the distribution of one right
(a "Right") for each common share outstanding from February 2, 1998 through the
distribution date (the "Distribution Date"). Each Right entitles the registered
holder, subject to the terms of the Rights Agreement, to purchase from the
Company one one-thousandth of a share (a "Unit") of Series A Preferred Stock at
an exercise price of $75 per Unit, subject to adjustment. The Distribution Date,
as defined in further detail within the Rights Agreement, is triggered when a
person acquires 15% of the outstanding common stock of the Company, or a tender
or exchange offer is commenced for 15% of such outstanding stock, except in
the case of two related party shareholders in which case the acquisition
threshold that applies is 20% of such outstanding stock. Under certain
circumstances thereafter, certain Rightholders may have the right to purchase
common stock of the Company, or of an Acquiring Person, as defined in the
Rights Agreement, having a value equal to two times the exercise price of the
Rights. In addition, the Rights are redeemable or exchangeable under certain
circumstances.


NOTE 16:  EVENTS OCCURRING SUBSEQUENT TO DATE OF AUDIT REPORT

In March 1998, the Company purchased an additional 10% interest in HER from an
existing shareholder of HER for ECU 13.5 million (approximately $14.6 million).
As a result of the purchase, the Company owns approximately 89% of HER.

                         Report of Independent Auditors



The Board of Directors and Shareholders
EDN Sovintel


We have audited the accompanying balance sheets of EDN Sovintel as of December
31, 1997 and 1996, and the related statements of income and retained earnings,
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of EDN Sovintel at December 31,
1997 and 1996, and the results of its operations and its cash flows for each of
the three years in the period ended December 31, 1997, in conformity with
accounting principles generally accepted in the United States of America.

We have also audited the financial statements of the Company at December 31,
1997 and 1996 and for each of the three years ended December 31, 1997, not
presented herewith, prepared in compliance with the regulations for bookkeeping
and accounting for income tax and statutory reporting purposes in the Russian
Federation on which we expect to report separately for the 1997 audited
financial statements and have reported separately for the 1996 and 1995
financial statements. The significant differences between the accounting
principles applied in preparing the statutory financial statements and
accounting principles generally accepted in the United States of America are
summarized in Note 2.

1.  DESCRIPTION OF BUSINESS

EDN Sovintel (the "Company") was created in August 1990 to design, construct,
and operate a telecommunications network in Moscow. This network provides
worldwide communications services, principally to major hotels, business offices
and mobile communication companies. Telecommunications services are subject to
local licensing. The Company's license for international, intercity and local
calls was most recently renewed on November 4, 1996 and is valid until May 1,
2000. The Company received a license for leased lines on September 20, 1996
valid for 5 years. The Company began operating in December 1991, providing
services under long-term contracts payable in US dollars.

The Company initially registered as a Soviet-American joint venture. The venture
re-registered as a Russian limited liability partnership in November 1992. The
Company is 50% owned by Open Joint Stock Company "Rostelecom", an intercity and
long-distance carrier which is 38% owned by Svyazinvest, and 50% owned by
Sovinet, a US general partnership, owned by two wholly-owned Global TeleSystems
Group, Inc. ("GTS") subsidiaries.

2.  BASIS OF PRESENTATION

The Company maintains its records and prepares its financial statements in
Russian roubles in accordance with the requirements of Russian accounting and
tax legislation. The accompanying financial statements differ from the financial
statements used for statutory purposes in Russia in that they reflect certain
adjustments, not recorded on the Company's books, which are appropriate to
present the financial position, results of operations and cash flows in
accordance with generally accepted accounting principles in the United States of
America ("US GAAP"). The principal adjustments are related to certain accrued
revenue and expenses, foreign currency translation, deferred taxation, and
depreciation and valuation of property and equipment.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements, in conformity with US GAAP, requires
management to make estimates and assumptions that affect the amounts reported in
the financial statements and accompanying notes. Actual results could differ
from those estimates.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

FOREIGN CURRENCY TRANSLATION

The Company's functional currency is the US dollar because the majority of its
revenues, costs, property and equipment purchased, and debt and trade
liabilities are either priced, incurred, payable or otherwise measured in US
dollars. Accordingly, transactions and balances not already measured in US
dollars (primarily Russian roubles) have been remeasured into US dollars in
accordance with the relevant provisions of US Financial Accounting Standard
("FAS") No. 52, "Foreign Currency Translation".

Under FAS No. 52, revenues, costs, capital and non-monetary assets and
liabilities are translated at historical exchange rates prevailing on the
transaction dates. Monetary assets and liabilities are translated at exchange
rates prevailing on the balance sheet date. Exchange gains and losses arising
from remeasurement of monetary assets and liabilities that are not denominated
in US dollars are credited or charged to operations.

The rouble is not a convertible currency outside the territory of Russia.
Official exchange rates are determined daily by the Central Bank of Russia
("CBR") and are generally considered to be a reasonable approximation of market
rates. The translation of rouble denominated assets and liabilities into US
dollars for the purpose of these financial statements does not indicate that the
Company could realize or settle in US dollars the reported values of the assets
and liabilities. Likewise, it does not indicate that the Company could return or
distribute the reported US dollar values of capital and retained earnings to its
shareholders.

The exchange rates at December 31, 1997, 1996 and 1995 for one US dollar were
RUR 5,960, RUR 5,560 and RUR 4,640 respectively. At February 16, 1998, the CBR
rate had changed to RUR 6,050. The effect of this devaluation of the rouble on
monetary assets and liabilities has not been determined.

On January 1, 1998, the CBR introduced a new rouble to replace existing roubles.
The new rouble has been redonominated so that one new rouble is equivalent to
one thousand old roubles. The old rouble will continue in circulation until
December 31, 1998 and will be accepted as legal tender until December 31, 2002.

All rouble amounts reflected in these financial statements are stated in old
roubles.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of cash on hand and in the bank.

ACCOUNTS RECEIVABLE

Accounts receivable are shown at their net realizable value which approximates
fair value. Accounts receivable are shown in the balance sheet net of an
allowance for uncollectible accounts of $643,000 and $900,000 at December 31,
1997 and 1996, respectively.

INVENTORIES

Inventories consist of telecommunications equipment held for resale and are
stated at the lower of cost or market. Cost is computed on a weighted average
basis.

PROPERTY AND EQUIPMENT

Property and equipment are recorded at their historical cost. Depreciation is
provided on the straight-line method over the following estimated useful lives:

     Network equipment                                         10 years
     Other property and equipment                             3-5 years

There is no depreciation charge for construction-in-progress. Depreciation
commences upon completion of the related project.

DEFERRED EXPENSES

Deferred expenses represent the Company's interest in the historical cost of
network equipment owned by MTU Inform, a partner in a commercial venture (Note
8). These expenses are amortized over the equipment's useful life of 10 years.

REVENUE RECOGNITION AND TAXES ON REVENUE

Revenues from telecommunication traffic are recognized in the period in which
the traffic occurs. Revenues from product sales, connection fees, and other
services are recognized in the period in which the products are shipped,
connections made, and services rendered. Taxes on certain revenues were charged
at rates ranging from 1.5% to 4.0% over the three years ended December 31, 1997,
1996 and 1995 and amounted to $4,458,000, $2,792,000 and $1,166,000,
respectively, and are charged to selling general and administrative expenses.

ADVERTISING

The Company expenses the cost of advertising as incurred. Advertising expenses
for the years ended December 31, 1997, 1996 and 1995 were $671,000, $512,000 and
$395,000, respectively, and are included in selling, general and administrative
expenses.

INVESTMENT INCENTIVE DEDUCTIONS

Russian legislation allows for certain additional tax deductions related to new
asset investments. These deductions are accounted for as a reduction to current
income taxes in the year in which they arise.

INCOME TAXES

The Company computes and records income taxes in accordance with FAS No. 109,
"Accounting for Income Taxes".

GOVERNMENT PENSION FUNDS

The Company contributes to the Russian Federation state pension fund, social
fund, medical insurance fund, unemployment fund and transport fund on behalf of
all its Russian employees. Contributions were 40.5%, 40.5% and 41.0% from base
payroll for 1997, 1996 and 1995, respectively.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value of financial instruments included in current assets and
liabilities is considered to be the carrying value.

NEW ACCOUNTING PRONOUNCEMENTS

In 1997, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of". SFAS 121 requires recognition of impairment of
long-lived assets in the event the net book value of such assets exceeds the
future undiscounted cash flows attributable to such assets. The adoption of SFAS
No. 121 had no impact on the Company's financial position or results of
operations.

In June 1997, SFAS No. 130, "Reporting Comprehensive Income", was issued. SFAS
No. 130 establishes standards for the reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements
and is effective for fiscal years beginning after December 15, 1997. The Company
will adopt SFAS No. 130 in fiscal 1998. SFAS No. 130 expands or modifies
disclosures and, accordingly, will have no impact on the Company's reported
financial position, results of operations or cash flows.

RECLASSIFICATIONS

Certain 1996 and 1995 comparative figures have been reclassified to conform to
the presentation adopted in the current year.

5.  INCOME TAXES (CONTINUED)

For financial reporting purposes, a valuation allowance has been recognised to
reflect management's estimate of the deferred tax assets that are less likely
than not to be realized.

The Company paid Russian profits tax of $4,302,000, $5,849,000 and $2,660,000 in
1997, 1996 and 1995, respectively.

6.  NOTE DUE TO SHAREHOLDER AND LONG-TERM DEBT

In October 1995, the Company entered into a $5,000,000 credit facility with
Sovinet, one of the Company's shareholders. It was subsequently increased to
$7,000,000. In January 1997, this facility was repaid and on January 16, 1997, a
new six-month facility was established with GTS Finance, Inc. for $7,000,000
which was then extended to December 19, 1997. The loan was repaid prior to
December 31, 1997 except for withholding taxes on interest. The loan carried
interest at a rate equal to the then current six month LIBOR rate (5.6%) plus
5.0 percent per annum. As of December 31, 1997, 1996 and 1995, the outstanding
borrowings under this agreement were $39,000, $5,700,000 and $5,500,000,
respectively.

The Company believes that the carrying value of the above loans approximates
fair values.

The Company paid interest of $697,000, $542,000 and $576,000 in 1997, 1996 and
1995, respectively.

256 billion roubles or approximately $42,953,000 at applicable year-end exchange

</TABLE>

At the request of Rostelecom, a shareholder, the Company placed a deposit of
2.65 billion roubles in August 1996 with a Russian bank related to this
shareholder. The bank deposit agreement states a deposit term of one year, which
was rolled over for an additional year during 1997. The deposit earns interest
quarterly at a rate of 15% per annum plus any devaluation losses against the US
dollar up to a maximum of 4.8% per quarter. Management is aware that the
deposited amount collateralizes certain obligations of the shareholder.

9.  CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS

Financial instruments that potentially subject the Company to concentration of
credit risk consist primarily of temporary cash deposits and trade accounts
receivables. The Company deposits its available cash with several Russian
financial institutions. The Company's sales and accounts receivable are made to
and due from a variety of international and Russian business customers. As of
December 31, 1997, two customers accounted for 16% and 11% of revenues and 11%
and 7% of accounts receivable, respectively. As of December 31, 1996, these same
two customers accounted for 17% and 16% of revenues and 25% and 10% of accounts
receivable, respectively. As of December 31, 1995, these two customers accounted
for 1% and 14% of revenues and 10% and 11% of accounts receivable, respectively.
The Company has no other significant concentrations of credit risk.

                   Notes to Financial Statements (continued)


10.  COMMITMENTS

The Company has several cancelable operating leases for office and warehouse
space and telecommunications lines with terms ranging from one to five years.

Total rent expense for 1997, 1996 and 1995 was $2,794,000, $2,137,000 and
$1,234,000, respectively.

11.  CONTINGENCIES

Legislation and regulations regarding taxation, foreign currency transactions
and licensing of foreign currency loans in the Russian Federation continues to
evolve as the central government manages the transformation from a command to a
market-oriented economy. The various legislation and regulations are not always
clearly written and their interpretation is subject to the opinions of the tax
inspectors, Central Bank officials and the Ministry of Finance. Instances of
inconsistent opinions between local, regional and national tax authorities and
between the Central Bank and Ministry of Finance are not unusual.

The Company believes that it has paid or accrued all taxes that are applicable.
Where practice concerning the provision of taxes is unclear, the Company has
accrued tax liabilities based on management's best estimate. The Company's
policy is to accrue contingencies in the accounting period in which a loss is
deemed probable and the amount is reasonably determinable.

Because of the uncertainties associated with the Russian tax and legal systems,
the ultimate amount of taxes, penalties and interest, if any, assessed may be in
excess of the amount expensed to date and accrued at December 31, 1997. It is
the opinion of the Company's management that any material amounts are either not
probable, not reasonably determinable, or both.

The Company's operations and financial position will continue to be affected by
Russian political developments, including the application of existing and future
legislation and tax regulations. The Company does not believe that these
contingencies, as related to its operations, are any more significant than those
of similar enterprises in Russia.

                         GLOBAL TELESYSTEMS GROUP, INC.



         GLOBAL TELESYSTEMS GROUP, INC., a Delaware corporation, HEREBY

         1. The name of the corporation is Global TeleSystems Group, Inc. The
date of filing of its Certificate of Incorporation with the Secretary of State
of the State of Delaware was September 30, 1993.

         2. This Certificate of Amendment sets forth amendments to the

adopted by the written consent of the holders of a majority of the outstanding
stock of the Corporation entitled to vote thereon in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware. Written notice of the taking of corporate action has been or shall be
given promptly in accordance with the provisions of Section 228 of the General
Corporation Law of the State of Delaware.

         3. Article SIXTH of the Certificate of Incorporation, as amended, of
the Corporation is hereby amended to read in full as follows:

         "SIXTH: The Corporation reserves the right to amend, alter, change or
         repeal any provision contained in this Certificate of Incorporation, in
         the manner now or hereafter prescribed by statute, and, except as
         provided in the next following sentence, all rights and powers
         conferred herein upon stockholders and directors are granted subject to
         this reservation. This Article Sixth and Article Eleventh of this
         Certificate of Incorporation of the Corporation, each as amended, and
         notwithstanding the fact that a lesser percentage may be specified by
         law, may not be amended, altered, changed or repealed without the
         affirmative vote of the holders of at least seventy-five percent (75%)
         of the shares of capital stock of the Corporation issued and
         outstanding and entitled to vote."

         4. The Certificate of Incorporation of the Corporation, as amended, is
hereby amended by inserting a new Article ELEVENTH as follows:



<PAGE>   2

         "ELEVENTH:  This Article is inserted for the management of the business
         and for the conduct of the affairs of the Corporation.

                  11.1. The number of directors of the Corporation shall not be
         less than three. The exact number of directors within the limitations
         specified in the preceding sentence shall be fixed from time to time
         by, or in the manner provided in, the Corporation's By-Laws.

                  11.2. The Board of Directors shall be and is divided into
         three classes: Class I, Class II and Class III. No one class shall have
         more than one director more than any other class. If a fraction is
         contained in the quotient arrived at by dividing the designated number
         of directors by three, then, if such fraction is one-third, the extra
         director shall be a member of Class I, and if such fraction is
         two-thirds, one of the extra directors shall be a member of Class I and
         one of the extra directors shall be a member of Class II, unless
         otherwise provided from time to time by resolution adopted by the Board
         of Directors.

                  11.3. Each director shall serve for a term ending on the date
         of the third annual meeting following the annual meeting at which such
         director was elected; provided, that each initial director in Class I
         shall serve for a term ending on the date of the annual meeting in
         1998; each initial director in Class II shall serve for a term ending
         on the date of the annual meeting in 1999; and each initial director in
         Class III shall serve for a term ending on the date of the annual
         meeting in 2000; and provided further, that the term of each director
         shall be subject to the election and qualification of his successor and
         to his earlier death, resignation or removal.


                  11.4. In the event of any increase or decrease in the
         authorized number of directors, (i) each director then serving as such
         shall nevertheless continue as a director of the class of which he is a
         member and (ii) the newly created or eliminated directorships resulting
         from such increase or decrease shall be apportioned by the Board of
         Directors among the three classes of directors so as to ensure that no
         one class has more than one director more than any other class. To the
         extent possible, consistent with the foregoing rule, any newly created
         directorships shall be added to those classes whose terms of office are
         to expire at the latest dates following such allocation, and any newly
         eliminated directorships shall be subtracted from those classes whose
         terms of offices are to expire at the earliest dates following such
         allocation, unless otherwise provided from time to time by resolution
         adopted by the Board of Directors.

<PAGE>   3

               11.5. A majority of the directors at any time in office shall
         constitute a quorum for the transaction of business. In the event one
         or more of the directors shall be disqualified to vote at any meeting,
         then the required quorum shall be reduced by one for each director so
         disqualified, provided that in no case shall less than one-third of the
         number of directors fixed pursuant to Article 11.1 above constitute a
         quorum. If at any meeting of the Board of Directors there shall be less
         than such a quorum, a majority of those present may adjourn the meeting
         from time to time. Every act or decision done or made by a majority of
         the directors present at a meeting duly held at which a quorum is
         present shall be regarded as the act of the Board of Directors unless a
         greater number is required by law, by the By-Laws of the Corporation or
         by this Certificate of Incorporation.

               11.6. Any vacancy in the Board of Directors, however occurring,
         including a vacancy resulting from an enlargement of the Board of
         Directors, shall be filled only by a vote of a majority of the
         directors then in office, although less than a quorum, or by a sole
         remaining director. A director elected to fill a vacancy shall be
         elected to hold office until the next election of the class for which
         such director shall have been chosen, subject to the election and
         qualification of his successor and to his earlier death, resignation or
         removal."

certificate to be signed by Grier C. Raclin, its Senior Vice President, General
Counsel and Secretary,  and attested by Arnold Y. Dean, its Assistant Secretary,

                      -----------------------------------

                         Pursuant to Section 151 of the
                           General Corporation Law of
                             the State of Delaware

                      -----------------------------------


                 I, Grier Raclin, Senior Vice President, General Counsel and
Secretary of Global TeleSystems Group, Inc., a corporation organized and
existing under the General Corporation Law of the State of Delaware (the
"Corporation"), DO HEREBY CERTIFY:

                 that, pursuant to authority conferred upon the Board of
Directors of the Corporation by its Certificate of Incorporation (the
"Certificate") and delegated to a committee of the Board of Directors of the
Corporation at a duly called meeting held on December 5, 1997, at which a
quorum was present and acted throughout, and, pursuant to the provisions of
Section 151 of the General Corporation Law of the State of Delaware, said
committee acting by unanimous written consent on January 30, 1998, adopted the
following resolutions, which resolutions remain in full force and effect on the
date hereof, creating a series of 200,000 shares of Preferred Stock having a
par value of $.0001 per share, designated as Series A Preferred Stock (the
"Series A Preferred Stock") out of the authorized preferred stock, par value of
$.0001 per share (the "Preferred Stock"):

                 RESOLVED, that pursuant to the authority vested in this
committee of the Board of Directors in accordance with the provisions of the
Certificate and resolutions of the Board or Directors duly adopted on December
5, 1997, this committee of the Board of Directors does hereby create, authorize
and provide for the issuance of the Series A Preferred Stock having the voting
powers, designation, relative, participating, optional and other special
rights, preferences, and qualifications, limitations and restrictions thereof
that are set forth as follows:

                 Section 1.  Designation and Amount.  The shares of such series
shall be designated as "Series A Preferred Stock" and the number of shares
constituting such series shall be 200,000.

                 Section 2.  Dividends and Distributions.  (A)  Subject to the
prior and superior rights of the holders of any shares of any other series of
Preferred Stock or any other shares of
<PAGE>   2
                                       2

preferred stock of the Corporation ranking prior and superior to the shares of
Series A Preferred Stock with respect to dividends, each holder of one
one-thousandth (1/1,000) of a share (a "Unit") of Series A Preferred Stock
shall be entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available for that purpose, (i) quarterly
dividends payable in cash on the last day of March, June, September and
December in each year (each such date being a "Quarterly Dividend Payment
Date"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of such Unit of Series A Preferred Stock, in an amount per Unit
(rounded to the nearest cent) equal to the greater of (a) $.01 or (b) subject
to the provision for adjustment hereinafter set forth, the aggregate per share
amount of all cash dividends declared on shares of the Common Stock since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of a Unit of
Series A Preferred Stock, and (ii) subject to the provision for adjustment
hereinafter set forth, quarterly distributions (payable in kind) on each
Quarterly Dividend Payment Date in an amount per Unit equal to the aggregate
per share amount of all non-cash dividends or other distributions (other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock, by reclassification or otherwise) declared on shares of
Common Stock since the immediately preceding Quarterly Dividend Payment Date,
or with respect to the first Quarterly Dividend Payment Date, since the first
issuance of a Unit of Series A Preferred Stock.  In the event that the
Corporation shall at any time after February 2, 1998 (the "Rights Declaration
Date") (i) declare any dividend on outstanding shares of Common Stock payable
in shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or
(iii) combine outstanding shares of Common Stock into a smaller number of
shares, then in each such case the amount to which the holder of a Unit of
Series A Preferred Stock was entitled immediately prior to such event pursuant
to the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which shall be the number of shares of Common Stock
that are outstanding immediately after such event and the denominator of which
shall be the number of shares of Common Stock that were outstanding immediately
prior to such event.

                 (B)      The Corporation shall declare a dividend or
distribution on Units of Series A Preferred Stock as provided in paragraph (A)
above immediately after it declares a dividend or distribution on the shares of
Common Stock (other than a dividend payable in shares of Common Stock);
provided, however, that, in the event no dividend or distribution shall have
been declared on the Common Stock during the period between any Quarterly
Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date,
a dividend of $0.01 per Unit on the Series A Preferred Stock shall nevertheless
be payable on such subsequent Quarterly Dividend Payment Date.

                 (C)      Dividends shall begin to accrue and shall be
cumulative on each outstanding Unit of Series A Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issuance of such
Unit of Series A Preferred Stock, unless the date of issuance of such  Unit is
prior to the record date for the first Quarterly Dividend Payment Date, in
which case, dividends on such Unit shall begin to accrue from the date of
issuance of such
<PAGE>   3
                                       3

Unit, or unless the date of issuance is a Quarterly Dividend Payment Date or is
a date after the record date for the determination of holders of Units of
Series A Preferred Stock entitled to receive a quarterly dividend and before
such Quarterly Dividend Payment Date, in either of which events such dividends
shall begin to accrue and be cumulative from such Quarterly Dividend Payment
Date.  Accrued but unpaid dividends shall not bear interest. Dividends paid on
Units of Series A Preferred Stock in an amount less than the aggregate amount
of all such dividends at the time accrued and payable on such Units shall be
allocated pro rata on a unit-by-unit basis among all Units of Series A
Preferred Stock at the time outstanding.  The Board of Directors may fix a
record date for the determination of holders of Units of Series A Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date
fixed for the payment thereof.

                 Section 3.  Voting Rights.  The holders of Units of Series A
Preferred Stock shall have the following voting rights:

         (A)     Subject to the provision for adjustment hereinafter set forth,
each Unit of Series A Preferred Stock shall entitle the holder thereof to one
vote on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time after the Rights Declaration
Date (i) declare any dividend on outstanding shares of Common Stock payable in
shares of Common Stock, (ii) subdivide outstanding shares of Common Stock or
(iii) combine the outstanding shares of Common Stock into a smaller number of
shares, then in each such case the number of votes per Unit to which holders of
Units of Series A Preferred Stock were entitled immediately prior to such event
shall be adjusted by multiplying such number by a fraction the numerator of
which shall be the number of shares of Common Stock outstanding immediately
after such event and the denominator of which shall be the number of shares of
Common Stock that were outstanding immediately prior to such event.

         (B)     Except as otherwise provided herein or by law, the holders of
Units of Series A Preferred Stock and the holders of shares of Common Stock
shall vote together as one class on all matters submitted to a vote of
stockholders of the Corporation.

         (C)     (i)  If at any time dividends on any Units of Series A
Preferred Stock shall be in arrears in an amount equal to six quarterly
dividends thereon, then during the period (a "default period") from the
occurrence of such event until such time as all accrued and unpaid dividends
for all previous quarterly dividend periods and for the current quarterly
dividend period on all Units of Series A Preferred Stock then outstanding shall
have been declared and paid or set apart for payment, all holders of Units of
Series A Preferred Stock, voting separately as a class, shall have the right to
elect two Directors.

         (ii)  During any default period, such voting rights of the holders of
Units of Series A Preferred Stock may be exercised initially at a special
meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any
annual meeting of stockholders, and thereafter at annual
<PAGE>   4
                                       4

meetings of stockholders, provided that neither such voting rights nor any
right of the holders of Units of Series A Preferred Stock to increase, in
certain cases, the authorized number of Directors may be exercised at any
meeting unless one-third of the outstanding Units of Preferred Stock shall be
present at such meeting in person or by proxy.  The absence of a quorum of the
holders of Common Stock shall not affect the exercise by the holders of Units
of Series A Preferred Stock of such rights.  At any meeting at which the
holders of Units of Series A Preferred Stock shall exercise such voting rights
initially during an existing default period, they shall have the right, voting
separately as a class, to elect Directors to fill up to two vacancies in the
Board of Directors, if any such vacancies may then exist, or, if such right is
exercised at an annual meeting, to elect two Directors.  If the number which
may be so elected at any special meeting does not amount to the required
number, the holders of the Series A Preferred Stock shall have the right to
make such increase in the number of Directors as shall be necessary to permit
the election by them of the required number.  After the holders of Units of
Series A Preferred Stock shall have exercised their right to elect Directors
during any default period, the number of Directors shall not be increased or
decreased except as approved by a vote of the holders of Units of Series A
Preferred Stock as herein provided or pursuant to the rights of any equity
securities ranking senior to the Series A Preferred Stock.

         (iii)  Unless the holders of Series A Preferred Stock shall, during an
existing default period, have previously exercised their right to elect
Directors, the Board of Directors may order, or any stockholder or stockholders
owning in the aggregate not less than 25% of the total number of the Units of
Series A Preferred Stock outstanding may request, the calling of a special
meeting of the holders of Units of Series A Preferred Stock, which meeting
shall thereupon be called by the Secretary of the Corporation.  Notice of such
meeting and of any annual meeting at which holders of Units of Series A
Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall
be given to each holder of record of Units of Series A Preferred Stock by
mailing a copy of such notice to him at his last address as the same appears on
the books of the Corporation.  Such meeting shall be called for a time not
earlier than 20 days and not later then 60 days after such order or request or
in default of the calling of such meeting within 60 days after such order or
request, such meeting may be called on similar notice by any stockholder or
stockholders owning in the aggregate not less than 25% of the total number of
outstanding Units of Series A Preferred Stock.  Notwithstanding the provisions
of this paragraph (C)(iii), no such special meeting shall be called during the
60 days immediately preceding the date fixed for the next annual meeting of the
stockholders.

         (iv)  During any default period, the holders of shares of Common Stock
and Units of Series A Preferred Stock, and other classes or series of stock of
the Corporation, if applicable, shall continue to be entitled to elect all the
Directors until holders of the Units of Series A Preferred Stock shall have
exercised their right to elect two Directors voting as a separate class, after
the exercise of which right (x) the Directors so elected by the holders of
Units of Series A Preferred Stock shall continue in office until their
successors shall have been elected by such holders or until the expiration of
the default period, and (y) any vacancy in the Board of Directors may (except
as provided in paragraph (C)(ii) of this Section 3) be filled by vote of
<PAGE>   5
                                       5

a majority of the remaining Directors theretofore elected by the holders of the
class of capital stock which elected the Director whose office shall have
become vacant.  References in this paragraph (C) to Directors elected by the
holders of a particular class of capital stock shall include Directors elected
by such Directors to fill vacancies as provided in clause (y) of the foregoing
sentence.

         (v)  Immediately upon the expiration of a default period, (x) the
right of the holders of Units of Series A Preferred Stock as a separate class
to elect Directors shall cease, (y) the term of any Directors elected by the
holders of Units of Series A Preferred Stock as a separate class shall
terminate, and (z) the number of Directors shall be such number as may be
provided for in the Certificate or by-laws irrespective of any increase made
pursuant to the provisions of paragraph (C)(ii) of this Section 3 (such number
being subject, however, to change thereafter in any manner provided by law or
in the Certificate or by-laws).  Any vacancies in the Board of Directors
effected by the provisions of clauses (y) and (z) in the preceding sentence may
be filled by a majority of the remaining Directors.

         (vi)  The provisions of this paragraph (C) shall govern the election
of Directors by holders of Units of Preferred Stock during any default period
notwithstanding any provisions of the Certificate to the contrary.

                 (D)      Except as set forth herein, holders of Units of
Series A Preferred Stock shall have no special voting rights and their consents
shall not be required (except to the extent they are entitled to vote with
holders of shares of Common Stock as set forth herein) for taking any corporate
action.

                 Section 4.  Certain Restrictions.  (A)  Whenever quarterly
dividends or other dividends or distributions payable on Units of Series A
Preferred Stock as provided in Section 2 are in arrears, thereafter and until
all accrued and unpaid dividends and distributions, whether or not declared, on
outstanding Units of Series A Preferred Stock shall have been paid in full, the
Corporation shall not

                 (i)  declare or pay dividends on, make any other distributions
         on, or redeem or purchase or otherwise acquire for consideration any
         shares of junior stock;

                 (ii)  declare or pay dividends on or make any other
         distributions on any shares of parity stock, except dividends paid
         ratably on Units of Series A Preferred Stock and shares of all such
         parity stock on which dividends are payable or in arrears in
         proportion to the total amounts to which the holders of such Units and
         all such shares are then entitled;

                 (iii)  redeem or purchase or otherwise acquire for
         consideration shares of any parity stock, provided, however, that the
         Corporation may at any time redeem, purchase or otherwise acquire
         shares of any such parity stock in exchange for shares of
<PAGE>   6
                                       6

         any junior stock;

                 (iv) purchase or otherwise acquire for consideration any Units
         of Series A Preferred Stock, except in accordance with a purchase
         offer made in writing or by publication (as determined by the Board of
         Directors) to all holders of such Units.

                 (B)      The Corporation shall not permit any subsidiary of
the Corporation to purchase or otherwise acquire for consideration any shares
of stock of the Corporation unless the Corporation could, under paragraph (A)
of this Section 4, purchase or otherwise acquire such shares at such time and
in such manner.

                 Section 5.  Reacquired Shares.  Any Units of Series A
Preferred Stock purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such Units shall, upon their cancellation, become authorized but
unissued Units of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

                 Section 6.  Liquidation, Dissolution or Winding Up.  (A)  Upon
any voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, no distribution shall be made (i) to the holders of shares of
junior stock unless the holders of Units of Series A Preferred Stock shall have
received, subject to adjustment as hereinafter provided in paragraph (B), the
greater of either (a) $0.01 per Unit plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not earned or declared, to the
date of such payment, or (b) the amount equal to the aggregate per share amount
to be distributed to holders of shares of Common Stock, or (ii) to the holders
of shares of parity stock, unless simultaneously therewith distributions are
made ratably on Units of Series A Preferred Stock and all other shares of such
parity stock in proportion to the total amounts to which the holders of Units
of Series A Preferred Stock are entitled under clause (i)(a) of this sentence
and to which the holders of shares of such parity stock are entitled, in each
case upon such liquidation, dissolution or winding up.

                 (B)      In the event the Corporation shall at any time after
the Rights Declaration Date (i) declare any dividend on outstanding shares of
Common Stock payable in shares of Common Stock, (ii) subdivide outstanding
shares of Common Stock, or (iii) combine outstanding shares of Common Stock
into a smaller number of shares, then in each such case the aggregate amount to
which holders of Units of Series A Preferred Stock were entitled immediately
prior to such event pursuant to clause (i)(b) of paragraph (A) of this Section
6 shall be adjusted by multiplying such amount by a fraction the numerator of
which shall be the number of shares of Common Stock that are outstanding
immediately after such event and the denominator of which shall be the number
of shares of Common Stock that were outstanding immediately prior to such
event.
<PAGE>   7
                                       7


                 Section 7.  Consolidation, Merger, etc.  In case the
Corporation shall enter into any consolidation, merger, combination or other
transaction in which the shares of common stock are exchanged for or converted
into other stock or securities, cash and/or any other property, then in any
such case Units of Series A Preferred Stock shall at the same time be similarly
exchanged for or converted into an amount per Unit (subject to the provision
for adjustment hereinafter set forth) equal to the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is converted or
exchanged.  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on outstanding shares of Common Stock
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common
Stock, or (iii) combine outstanding Common Stock into a smaller number of
shares, then in each such case the amount set forth in the immediately
preceding sentence with respect to the exchange or conversion of Units of
Series A Preferred Stock shall be adjusted by multiplying such amount by a
fraction the numerator of which shall be the number of shares of Common Stock
that are outstanding immediately after such event and the denominator of which
shall be the number of shares of Common Stock that were outstanding immediately
prior to such event.

                 Section 8.  Redemption.  The Units of Series A Preferred Stock
shall not be redeemable.

                 Section 9.  Ranking.  The Units of Series A Preferred Stock
shall rank junior to all other series of the Preferred Stock and to any other
class of preferred stock that hereafter may be issued by the Corporation as to
the payment of dividends and the distribution of assets, unless the terms of
any such series or class shall provide otherwise.

                 Section 10.  Amendment.  The Certificate, including, without
limitation, this resolution, shall not hereafter be amended, either directly or
indirectly, or through merger or consolidation with another corporations in any
manner that would alter or change the powers, preferences or special rights of
the Series A Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority or more of the outstanding Units
of Series A Preferred Stock, voting separately as a class.

                 Section 11.  Fractional Shares.  The Series A Preferred Stock
may be issued in Units or other fractions of a share, which Units or fractions
shall entitle the holder, in proportion to such holder's fractional shares, to
exercise voting rights, receive dividends, participate in distributions and to
have the benefit of all other rights of holders of Series A Preferred Stock.

                 Section 12.  Certain Definitions.  As used herein with respect
to the Series A Preferred Stock, the following terms shall have the following
meanings:

                 (A)      The term "Common Stock" shall mean the class of stock
designated as the common stock, par value $0.10 per share, of the Corporation
at the date hereof or any

                                       8

other class of stock resulting from successive changes or reclassification of
such common stock.

                 (B)      The term "junior stock" (i) as used in Section 4,
shall mean the Common Stock and any other class or series of capital stock of
the Corporation hereafter authorized or issued over which the Series A
Preferred Stock has preference or priority as to the payment of dividends and
(ii) as used in Section 6, shall mean the Common Stock and any other class or
series of capital stock of the Corporation over which the Series A Preferred
Stock has preference or priority in the distribution of assets on any
liquidation, dissolution or winding up of the Corporation.

                 (C)      The term "parity stock" (i) as used in Section 4,
shall mean any class or series of stock of the Corporation hereafter authorized
or issued ranking pari passu with the Series A Preferred Stock as to the
payment of dividends and (ii) as used in Section 6, shall mean any class or
series of capital stock ranking pari passu with the Series A Preferred Stock in

Person which is redeemed, defeased, retired or otherwise repaid at the time of
or immediately upon consummation of the transactions by which such Person
becomes a Restricted Group Member or is merged or consolidated with or into the
Company or any Restricted Group Member, or such Acquisition shall not be

Member or its Equity Interest holders; provided, however, that with respect to
any restriction on the declaration or payment of dividends or similar
distribution in place on the Issue Date pursuant to any agreement in effect on
the Issue Date (or any amendment or modification thereto no more restrictive

connection with a Restricted Payment described in clauses (i), (ii) and (iii)
of the first paragraph of Section 4.11; and (g) to the extent not otherwise

capitalized debt issuance costs for such period, all of the foregoing
determined in accordance with GAAP minus non-cash items to the extent they
increase Adjusted Net Income (including the partial or entire reversal of
reserves taken in prior periods) for such period. In calculating

GAAP), after deducting therefrom (i) all current liabilities of the Company and
such Restricted Group Members; and (ii) all goodwill, trade names, trademarks,

time during the continuance of any payment Default, upon written request to a
Paying Agent, require such Paying Agent to distribute all assets held by it to
the Trustee and to account for any assets distributed.  Upon distribution to
the Trustee of all assets that shall have been delivered by the Company to the
Paying Agent (if other than the Company), the Paying Agent shall have no
further liability for such assets.  If the Company or any Subsidiary acts as
Paying Agent, it shall, on or before each due date of the principal of or
interest on the Securities, segregate and





<PAGE>   28
                                      -22-


hold in trust for the benefit of the Persons entitled thereto a sum sufficient
to pay the principal or interest so becoming due until such sums shall be paid
to such Persons or otherwise disposed of as herein provided and will promptly
notify the Trustee of its action or failure so to act.

SECTION 2.05.  Securityholder Lists.

                 The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders.  If the Trustee is not the Registrar, the Company shall
furnish to the Trustee as soon as possible after each Interest Record Date and
at such other times as the Trustee may request in writing a list as of such
date and in such form as the Trustee may reasonably require of the names and
addresses of Holders, which list may be conclusively relied upon by the
Trustee.

SECTION 2.06.  Transfer and Exchange.

                 Subject to the provisions of Sections 2.15 and 2.16, when
Securities are presented to the Registrar or a co-Registrar with a request to
register the transfer of such Securities or to exchange such Securities for an
equal principal amount of Securities of other authorized denominations of the
same series, the Registrar or co-Registrar shall register the transfer or make
the exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar or co-Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.  To
permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Securities at the Registrar's or co-Registrar's
written request.  No service charge shall be made for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient
to cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or other governmental charge
payable upon exchanges or transfers pursuant to Section 2.02, 2.10, 3.06, 4.10,
4.16 or 9.05).  The Registrar or co-Registrar shall not be required to register
the transfer or exchange of any Security (i) during a period beginning at the
opening of business 15 days before the mailing of a notice of redemption of
Securities and ending at the close of business on the day of such mailing and
(ii) selected for redemption in whole or in part pursuant to Article Three
hereof, except the unredeemed portion of any Security being redeemed in part.

                 Prior to the registration of any transfer by a Holder as
provided herein, the Company, the Trustee, and any Agent of the Company shall
treat the person in whose name the Security is registered as the owner thereof
for all purposes whether or not the Security shall be overdue, and neither the
Company, the Trustee, nor any such Agent shall be affected by notice to the
contrary.  Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book-entry system maintained by the Depository
(or its agent), and that ownership of a beneficial interest in a Global
Security shall be required to be reflected in a book entry.

SECTION 2.07.  Replacement Securities.

                 If a mutilated Security is surrendered to the Trustee or if
the Holder of a Security claims that the Security has been lost, destroyed or
wrongfully taken, the Company shall issue and the Trustee shall authenticate a
replacement Security if the Trustee's requirements for replacement of
Securities are met.  Such Holder must provide an indemnity bond or other
indemnity, sufficient in the judgment of both the Company and the Trustee, to
protect the Company, the Trustee and any Agent from any loss which any of them
may suffer if a Security is replaced and evidence to their satisfaction of the
apparent loss, destruction or theft of such Security.  The Company may charge
such Holder for its reasonable out-of-pocket expenses in replacing a Security,
in-





<PAGE>   29
                                      -23-


cluding reasonable fees and expenses of counsel.  In case any such mutilated,
lost, destroyed or wrongfully taken Security has become or is about to become
due and payable, the Company in its discretion may pay such Security instead of
issuing a new Security in replacement thereof.

                 Every replacement Security is an additional obligation of the
Company.

SECTION 2.08.  Outstanding Securities.

                 Securities outstanding at any time are all the Securities that
have been authenticated by the Trustee except those cancelled by it, those
delivered to it for cancellation and those described in this Section 2.08 as
not outstanding.  Subject to Section 2.09, a Security does not cease to be
outstanding because the Company or any of its Affiliates holds the Security.

                 If a Security is replaced pursuant to Section 2.07 (other than
a mutilated Security surrendered for replacement), it ceases to be outstanding
unless a Trust Officer of the Trustee receives proof satisfactory to him that
the replaced Security is held by a bona fide purchaser.  A mutilated Security
ceases to be outstanding upon surrender of such Security and replacement
thereof pursuant to Section 2.07.

                 If on a Redemption Date, Purchase Date or the Maturity Date
the Paying Agent holds money sufficient to pay all of the principal and
interest due on the Securities payable on that date, then on and after that
date such Securities cease to be outstanding and interest on them ceases to
accrue.

SECTION 2.09.  Treasury Securities.

                 In determining whether the Holders of the required principal
amount of Securities have concurred in any direction, waiver or consent,
Securities owned by the Company or any of its Affiliates shall be disregarded,
except that, for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities
that a Trust Officer of the Trustee actually knows are so owned shall be
disregarded.  Securities so owned which have been pledged in good faith may be
regarded as outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Securities and that
the pledgee is not the Company or any other obligor upon the Securities or any
Affiliate of the Company or of such other obligor.

SECTION 2.10.  Temporary Securities.

                 Until definitive Securities are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive
Securities but may have variations that the Company considers appropriate for
temporary Securities.  Without unreasonable delay, the Company shall prepare
and the Trustee shall authenticate upon receipt of a written order of the
Company pursuant to Section 2.02 definitive Securities in exchange for
temporary Securities.

SECTION 2.11.  Cancellation.

                 The Company at any time may deliver Securities to the Trustee
for cancellation.  The Registrar and the Paying Agent shall forward to the
Trustee any Securities surrendered to them for transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel all Securities surrendered for transfer,
exchange, payment or cancellation and deliver to the Company such cancelled
Securities for disposal.  Subject to Section 2.07, the Company may not issue
new Securities





<PAGE>   30
                                      -24-


to replace Securities that it has paid or delivered to the Trustee for
cancellation.  If the Company shall acquire any of the Securities, such
acquisition shall not operate as a redemption or satisfaction of the
Indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 2.11.  The
Trustee shall cancel all Securities surrendered for transfer, exchange, payment
or cancellation and shall dispose of them in accordance with its normal
procedure.

SECTION 2.12.  Defaulted Interest.

                 If the Company defaults in a payment of principal or interest
on the Securities, it shall pay interest on overdue principal and on overdue
installments of interest (without regard to any applicable grace periods) from
time to time on demand at the rate per annum borne by the Securities, to the
extent lawful.

SECTION 2.13.  CUSIP Number.

                 The Company in issuing the Securities will use one or more
"CUSIP" numbers and the Trustee shall use the appropriate CUSIP number in
notices of redemption or exchange as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to
the correctness or accuracy of the CUSIP number printed in the notice or on the
Securities, and that reliance may be placed only on the other identification
numbers printed on the Securities.  The Company shall promptly notify the
Trustee of any changes in CUSIP numbers.

SECTION 2.14.  Deposit of Moneys.

                 Prior to 10:00 a.m. New York City time on each Interest
Payment Date, Redemption Date, Purchase Date and the Maturity Date, the Company
shall deposit with the Paying Agent in immediately available funds money
sufficient to make cash payments, if any, due on such Interest Payment Date,
Redemption Date, Purchase Date or Maturity Date, as the case may be, in a
timely manner which permits the Paying Agent to remit payment to the Holders on
such Interest Payment Date, Redemption Date, Purchase Date or Maturity Date, as
the case may be.

SECTION 2.15.  Book-Entry Provisions for Global Securities.

                 (a)  The Global Securities initially shall (i) be registered
in the name of the Depository or the nominee of such Depository, (ii) be
delivered to the Trustee as custodian for such Depository and (iii) bear
legends as set forth in Exhibit B hereto.

                 Members of, or participants in, the Depository
("Participants") shall have no rights under this Indenture with respect to any
Global Security held on their behalf by the Depository, or the Trustee as its
custodian, or under such Global Security, and the Depository may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and Participants, the operation of
customary practices governing the exercise of the rights of a beneficial owner
of any Security.

                 (b)  Transfers of Global Securities shall be limited to
transfers in whole, but not in part, to the Depository, its successors or their
respective nominees.  Physical Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in Global
Securities if (i) the Depository notifies the Company





<PAGE>   31
                                      -25-


that it is unwilling or unable to continue as Depository for any Global
Security and a successor Depository is not appointed by the Company within 90
days of such notice or (ii) an Event of Default has occurred and is continuing
and the Registrar has received a request from the Depository to issue Physical
Securities.

                 (c)  In connection with the transfer of Global Securities as
an entirety to beneficial owners pursuant to paragraph (b) of this Section
2.15, the Global Securities shall be deemed to be surrendered to the Trustee
for cancellation, and the Company shall execute, and the Trustee shall upon
written instructions from the Company authenticate and make available for
delivery, to each beneficial owner identified by the Depository in exchange for
its beneficial interest in the Global Securities, an equal aggregate principal
amount of Physical Securities of authorized denominations.

                 (d)  The Holder of any Global Security may grant proxies and
otherwise authorize any Person, including Participants and Persons that may
hold interests through Participants, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

SECTION 2.16.  Registration of Transfers and Exchanges.

                 (a)  Transfer and Exchange of Physical Securities.  When
Physical Securities are presented to the Registrar or co-Registrar with a
request:

                (i)    to register the transfer of the Physical Securities; or

               (ii)    to exchange such Physical Securities for an equal
         principal amount of Physical Securities of other authorized
         denominations,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if the requirements under this Indenture as set forth in this
Section 2.16 for such transactions are met; provided, however, that the
Physical Securities presented or surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Registrar or co-Registrar, duly executed
by the Holder thereof or his attorney duly authorized in writing.

                 (b)  Transfer and Exchange of Global Securities.  The transfer
and exchange of Global Securities or beneficial interests therein shall be
effected through the Depository in accordance with this Indenture and the
procedures of the Depository therefor.

                 (c)  Restrictions on Transfer and Exchange of Global
Securities.  Notwithstanding any other provisions of this Indenture, a Global
Security may not be transferred as a whole except by the Depository to a
nominee of the Depository or by a nominee of the Depository to the Depository
or another nominee of the Depository or by the Depository or any such nominee
to a successor Depository or a nominee of such successor Depository.

                 (d)  General.  The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Indenture or under applicable law with respect to
any transfer of any interest in any Security (including any transfers between
or among Participants or beneficial owners of interest in any Global Security)
other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by the terms of, this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.





<PAGE>   32
                                      -26-


                 The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.15 or this Section
2.16.  The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon
the giving of reasonable written notice to the Registrar.

                                 ARTICLE THREE

                                   REDEMPTION

SECTION 3.01.  Notices to Trustee.

                 If the Company elects to redeem Securities pursuant to
paragraph 5 of the Securities at the applicable redemption price set forth
thereon, it shall notify the Trustee in writing of the Redemption Date and the
principal amount of Securities to be redeemed. The Company shall give such
notice to the Trustee at least 45 days before the Redemption Date (unless a
shorter notice shall be agreed to by the Trustee in writing), together with an
Officers' Certificate stating that such redemption will comply with the
conditions contained herein.

SECTION 3.02.  Selection of Securities to Be Redeemed.

                 If less than all of the Securities are to be redeemed pursuant
to paragraph 5(a) or (b) of the Securities, the Trustee shall select the
Securities to be redeemed in compliance with the requirements of the principal
national securities exchange, if any, on which the Securities are listed or, if
the Securities are not then listed on a national securities exchange, on a pro
rata basis, by lot or by such other manner as the Trustee shall deem fair and
appropriate; provided, however, that (1) no Securities of a principal amount of
$1,000 or less shall be redeemed in part and (2) if a partial redemption is
made pursuant to the provisions of paragraph 5 of the Securities, selection of
the Securities or portions thereof for redemption shall be made by the Trustee
only on a pro rata basis or on as nearly a pro rata basis as is practicable
(subject to the procedures of the Depository), unless such method is otherwise
prohibited.  The Trustee shall make the selection from the Securities then
outstanding, subject to redemption and not previously called for redemption.

                 The Trustee may select for redemption pursuant to paragraph
5(a) or (b) of the Securities portions of the principal amount of Securities
that have denominations equal to or larger than $1,000 principal amount.
Securities and portions of them the Trustee so selects shall be in amounts of
$1,000 principal amount or integral multiples thereof. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption.

SECTION 3.03.  Notice of Redemption.

                 At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail a notice of redemption by first-class mail to each
Holder whose Securities are to be redeemed at such Holder's registered address;
provided, however, that notice of a redemption pursuant to paragraph 5(b) of
the Securities shall be mailed to each Holder whose Securities are to be
redeemed no later than 60 days following the consummation of the last Public
Equity Offering or Strategic Equity Investment resulting in gross cash proceeds
to the Company, when aggregated with all prior Public Equity Offerings and
Strategic Equity Investments, of at least $75.0 million.





<PAGE>   33
                                      -27-



                 Each notice of redemption shall identify the Securities to be
redeemed (including the CUSIP number thereon) and shall state:

                 (1)      the Redemption Date;

                 (2)      the redemption price;

                 (3)      the name and address of the Paying Agent to which the
         Securities are to be surrendered for redemption;

                 (4)      that Securities called for redemption must be
         surrendered to the Paying Agent to collect the redemption price;

                 (5)      that, unless the Company defaults in making the
         redemption payment, interest on Securities called for redemption
         ceases to accrue on and after the Redemption Date and the only
         remaining right of the Holders is to receive payment of the redemption
         price upon surrender to the Paying Agent; and

                 (6)      if any Security is being redeemed in part, the
         portion of the principal amount of such Security to be redeemed and
         that, after the Redemption Date, upon surrender of such Security, a
         new Security or Securities in principal amount equal to the unredeemed
         portion thereof will be issued.

                 At the Company's request, the Trustee shall give the notice of
redemption on behalf of the Company, in the Company's name and at the Company's
expense.

SECTION 3.04.  Effect of Notice of Redemption.

                 Once a notice of redemption is mailed, Securities called for
redemption become due and payable on the Redemption Date and at the redemption
price. Upon surrender to the Paying Agent, such Securities shall be paid at the
redemption price, plus accrued interest thereon, if any, to the Redemption
Date, but interest installments whose maturity is on or prior to such
Redemption Date shall be payable to the Holders of record at the close of
business on the relevant Interest Record Date.

SECTION 3.05.  Deposit of Redemption Price.

                 Prior to 10:00 a.m. New York City time on the Redemption Date,
the Company shall deposit with the Paying Agent (or if the Company is its own
Paying Agent, shall, on or before the Redemption Date, segregate and hold in
trust) money sufficient to pay the redemption price of and accrued interest, if
any, on all Securities to be redeemed on that date other than Securities or
portions thereof called for redemption on that date which have been delivered
by the Company to the Trustee for cancellation.

                 If any Security surrendered for redemption in the manner
provided in the Securities shall not be so paid on the Redemption Date due to
the failure of the Company to deposit with the Paying Agent money sufficient to
pay the redemption price thereof, the principal and accrued and unpaid
interest, if any, thereon shall, until paid or duly provided for, bear interest
as provided in Sections 2.12 and 4.01 with respect to any payment default.

SECTION 3.06.  Securities Redeemed in Part.

                 Upon surrender of a Security that is redeemed in part, the
Trustee shall authenticate for the Holder a new Security equal in principal
amount to the unredeemed portion of the Security surrendered.

                                  ARTICLE FOUR

                                   COVENANTS

SECTION 4.01.  Payment of Securities.

                 The Company shall pay the principal of and interest on the
Securities in the manner provided in the Securities. An installment of
principal or interest shall be considered paid on the date due if the Trustee
or Paying Agent (other than the Company, a Subsidiary or an Affiliate of the
Company) holds on that date money designated for and sufficient to pay the
installment in full and is not prohibited from paying such money to the Holders
of the Securities pursuant to the terms of this Indenture.

                 The Company shall pay cash interest on overdue principal at
the same rate per annum borne by the Securities. The Company shall pay cash
interest on overdue installments of interest at the same rate per annum borne
by the Securities, to the extent lawful, as provided in Section 2.12.

SECTION 4.02.  Maintenance of Office or Agency.

                 The Company shall maintain in the Borough of Manhattan, The
City of New York, the office or agency required under Section 2.03.  The
Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 10.02 hereof.  The Company hereby initially
designates the Trustee at its address set forth in Section 10.02 hereof as its
office or agency in The Borough of Manhattan, The City of New York, for such
purposes.

SECTION 4.03.  Corporate Existence.

                 Subject to Article Five, the Company shall do or shall cause
to be done all things necessary to preserve and keep in full force and effect
its corporate existence and the corporate, partnership or other existence of
each Restricted Subsidiary in accordance with the respective organizational
documents of each such Restricted Subsidiary and the rights (charter and
statutory) and material franchises of the Company and the Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right or franchise, or the corporate existence of any
Restricted Subsidiary, if the Board of Directors of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and the Restricted Subsidiaries, taken as a whole, and
that the loss thereof is not, and will not be, adverse in any material respect
to the Holders; provided, further, however, that a determination of the Board
of Directors of the Company shall not be required in the event of a merger of
one or more Wholly Owned Restricted Subsidiaries of the Company with or into
another Wholly Owned Restricted Subsidiary of the Company or another Person, if
the surviving Person is a Wholly Owned Restricted Subsidiary of the Company
organized under the laws of the United States or a State thereof or of the
District of Columbia.

SECTION 4.04.  Payment of Taxes and Other Claims.

                 The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any
Restricted Subsidiary or upon the income, profits or property of the Company or
any Restricted Subsidiary and (2) all lawful claims for labor, materials and
supplies which, in each case, if unpaid, might by law become a material
liability, or Lien upon the property, of the Company or any Restricted
Subsidiary; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings and for which appropriate provision has been made.

SECTION 4.05.  Notice of Defaults.

                 (a)  In the event that any Indebtedness of the Company or any
of its Subsidiaries is declared due and payable before its maturity because of
the occurrence of any default (or any event which, with notice or lapse of
time, or both, would constitute such a default) under such Indebtedness, the
Company shall promptly give written notice to a Trust Officer of the Trustee of
such declaration, the status of such default or event and what action the
Company is taking or proposes to take with respect thereto.

                 (b)  Upon becoming aware of any Default, the Company shall
promptly deliver an Officers' Certificate to a Trust Officer of the Trustee
specifying the Default.

SECTION 4.06.  Maintenance of Properties and Insurance.

                 (a)  The Company shall cause all material properties owned by
or leased to it or any Restricted Subsidiary and used or useful in the conduct
of its business or the business of any Restricted Subsidiary to be maintained
and kept in normal condition, repair and working order and supplied with all
necessary equipment and shall cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary, so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section 4.06 shall prevent the Company or any
Restricted Subsidiary from discontinuing the use, operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors or of the board of
directors of the Restricted Subsidiary concerned, or of an officer (or other
agent employed by the Company or of any Restricted Subsidiary) of the Company
or such Restricted Subsidiary having managerial responsibility for any such
property, desirable in the conduct of the business of the Company or any
Restricted Subsidiary, and if such discontinuance or disposal is not adverse in
any material respect to the Holders.

                 (b)  The Company shall maintain, and shall cause the
Restricted Subsidiaries to maintain, insurance with responsible carriers
against such risks and in such amounts, and with such deductibles, retentions,
self-insured amounts and co-insurance provisions, as are customarily carried by
similar businesses of similar size, including property and casualty loss, and
workers' compensation insurance.

SECTION 4.07.  Compliance Certificate.

                 The Company shall deliver to the Trustee within 120 days after
the close of each fiscal year a certificate signed by the principal executive
officer, principal financial officer or principal accounting officer stating
that a review of the activities of the Company has been made under the
supervision of the signing officers





<PAGE>   36
                                      -30-


with a view to determining whether a Default has occurred and whether or not
the signers know of any Default by the Company that occurred during such fiscal
year. If they do know of such a Default, the certificate shall describe all
such Defaults, their status and the action the Company is taking or proposes to
take with respect thereto. The first certificate to be delivered by the Company
pursuant to this Section 4.07 shall be for the fiscal year ending December 31,
1998.

SECTION 4.08.  Waiver of Stay, Extension or Usury Laws.

                 The Company covenants (to the extent that it may lawfully do
so) that it shall not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
or any usury law or other law, which would prohibit or forgive the Company from
paying all or any portion of the principal of and/or interest, if any, on the
Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of
this Indenture; and (to the extent that it may lawfully do so) the Company
hereby expressly waives all benefit or advantage of any such law, and covenants
that it shall not hinder, delay or impede the execution of any power herein
granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law had been enacted.

SECTION 4.09.  Provision of Financial Information.

                 Whether or not the Company is subject to Section 13(a) or
15(d) of the Exchange Act, or any successor provision thereto, the Company
shall file with the SEC (if permitted by SEC practice and applicable law and
regulations) the annual reports, quarterly reports and other documents which
the Company would have been required to file with the SEC pursuant to such
Section 13(a) or 15(d) or any successor provision thereto if the Company were
so required, such documents to be filed with the SEC on or prior to the
respective dates (the "Required Filing Dates") by which the Company would have
been required so to file such documents if the Company were so required. The
Company shall also in any event (a) within 15 days of each Required Filing Date
(whether or not permitted or required to be filed with the SEC) (i) transmit
(or cause to be transmitted) by mail to all Holders, as their names and
addresses appear in the Securities register, without cost to such Holders, and
(ii) file with the Trustee, copies of the annual reports, quarterly reports and
other documents which the Company is required to file with the SEC pursuant to
the preceding sentence, or, if such filing is not so permitted, information and
data of a similar nature, and (b) if, notwithstanding the preceding sentence,
filing such documents by the Company with the SEC is not permitted by SEC
practice or applicable law or regulations, promptly upon written request supply
copies of such documents to any Holder.  Delivery of such reports, information
and documents to the Trustee is for informational purposes only and the
Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers'
Certificates).

SECTION 4.10.  Change of Control.

notify the Holders of such occurrence in the manner prescribed by this
Indenture and shall, within 30 days after the Change of Control Date, make an
Offer to Purchase all Securities then outstanding at a purchase price in cash
equal to 101% of the principal amount thereof, plus accrued and unpaid interest
thereon, if any, to the date of purchase. The Company's obligations may be
satisfied if a third party makes the Offer to Purchase in the manner, at the
times and otherwise in compliance with the requirements of this Indenture
applicable to an Offer to Purchase made by the Company and purchases all
Securities validly tendered and not withdrawn under such Offer to Purchase.
Each Holder shall be entitled to tender all or any

portion of the Securities owned by such Holder pursuant to the Offer to
Purchase, subject to the requirement that any portion of a Security tendered
must be tendered in an integral multiple of $1,000 principal amount.

                 (b)  On or prior to the Purchase Date specified in the Offer
to Purchase, the Company shall (i) accept for payment all Securities or
portions thereof validly tendered pursuant to the Offer, (ii) deposit with the
Paying Agent or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 2.04, money sufficient to pay the
Purchase Price of all Securities or portions thereof so accepted and (iii)
deliver or cause to be delivered to the Trustee for cancellation all Securities
so accepted together with an Officers' Certificate stating the Securities or
portions thereof accepted for payment by the Company. The Paying Agent (or the
Company, if so acting) shall promptly mail or make available for delivery to
Holders of Securities so accepted, payment in an amount equal to the Purchase
Price for such Securities, and the Trustee shall promptly authenticate and mail
or make available for delivery to each Holder of Securities a new Security or
Securities equal in principal amount to any unpurchased portion of the Security
surrendered as requested by the Holder. Any Security not accepted for payment
shall be promptly mailed or delivered by the Company to the Holder thereof. The
Company shall publicly announce the results of the Offer on or as soon as
practicable after the Purchase Date.

                 (c)  If the Company makes an Offer to Purchase, the Company
will comply with all applicable tender offer laws and regulations, including,
to the extent applicable, Section 14(e) and Rule 14e-1 under the Exchange Act,
and any other applicable Federal or state securities laws and regulations and
any applicable requirements of any securities exchange on which the Securities
are listed, and any violation of the provisions of this Indenture relating to
such Offer to Purchase occurring as a result of such compliance shall not be
deemed a Default.

paragraph of this covenant; or (vii) Investments in a Person which has ceased
to be a Restricted Affiliate or ceases to observe any of the provisions of the
covenants applicable to it as a result of an Involuntary Event if (a) such
Investment is made with the proceeds of a substantially concurrent capital
contribution to the Company from any Person (other than a Restricted Group

                (i)    at the date that any Restricted Group Member ceases to
         be a Restricted Group Member for any reason (other than by virtue of a
         Designation), including without limitation, by virtue of any
         transaction permitted by clause (iii) of Section 4.19, in an amount
         equal to the greater of (I) $0 and (II) the lesser of (A) the Fair

         aggregate amount of Investments made prior to such date in such
         Restricted Group Member by the Company or any Restricted Group Member
         (valued in each case at the time such Investment was made) over the
         net reduction of such Investments; and

               (ii)    at the time that any Investment has ceased to be a
         Permitted Investment pursuant to clause (j)(II) of the definition of
         Permitted Investments, in an amount equal to the Fair Market Value of
         such Investment at the time it was made.

Restricted Group Member to, directly or indirectly, Incur any Indebtedness

              (iii)    indebtedness of the Company pursuant to the Senior
         Credit Facility in an aggregate amount at any time outstanding not to
         exceed $100.0 million;

               (iv)     Indebtedness of the Company or any Restricted Group
         Member, in each case, to the extent that the proceeds of or credit
         support provided by such Indebtedness is used to finance the cost
         (including the cost of design, development, construction, installation
         or integration) of network assets, equipment or inventory acquired by

         Acquired Indebtedness in connection with the consummation of) a
         Telecommunications Acquisition (or is used to provide working capital
         for, or to finance the construction of, the business or network
         acquired), and, in each case, Permitted Refinancings thereof, but in
         each case only to the extent that the aggregate amount of outstanding
         Indebtedness of the Company and the Restricted Group Members
         immediately after giving effect to the Incurrence of such Indebtedness
         and the application of the proceeds therefrom does not exceed the

         under the Securities; provided, however, that an Incurrence of
         Indebtedness that is not permitted by this clause (vii) shall be
         deemed to have occurred upon (x) any sale or other disposition of any
         Indebtedness of the Company or any Restricted Group Member referred to
         in this clause (vii) to any Person other than the Company or any
         Restricted Group Member or (y) any Restricted Group Member that holds

         is otherwise permitted to be Incurred under this covenant); provided,
         however, that the notional principal amount of such Interest Rate
         Protection Obligations does not exceed the principal amount of the

         such Restricted Group Member, as the case may be; provided, however,
         that such Currency Agreements do not increase the Indebtedness or
         other obligations of the Company and the Restricted Group Members
         outstanding other than as a result of fluctuations in foreign currency
         exchange rates or by reason of fees, indemnities or compensation
         payable thereunder;

                (x)    Indebtedness of the Company and/or any Restricted Group
         Member in respect of performance bonds of the Company or any

         or from guarantees or letters of credit, surety bonds or performance
         bonds securing any obligations of the Company or any Restricted Group
         Member pursuant to such agreements, in any case Incurred in connection
         with the disposition of any business, assets or Restricted Group
         Member (other than guarantees of Indebtedness Incurred by any Person
         acquiring all or any portion of such business, assets or Restricted
         Group Member for the purpose of financing such acquisition), in a
         principal amount not to exceed the gross proceeds actually received by
         the Company or any Restricted Group Member in connection with such
         disposition;

              (xii)    Indebtedness of the Company or any Restricted Group
         Member so long as the sum of (1) the aggregate amount of Indebtedness
         Incurred and outstanding by the Company pursuant to this clause (xii)
         and (2) the product of 2.0 and the aggregate amount of Indebtedness
         Incurred and outstanding by the Restricted Group Members
         (collectively) pursuant to this clause (xii) does not exceed the
         product of 2.0 and (A) 100% of the Net Proceeds received by the
         Company after the Issue Date from contributions of capital or the
         issuance and sale of its Qualified Equity Interests to any Person
         (other than any Restricted Group Member) and (B) 80% of the Net
         Proceeds of property other than cash received by the Company after the
         Issue Date from contributions of capital or the issuance and sale of
         its Qualified Equity Interests to any Person (other than any
         Restricted Group Member), in each case (A) and (B) only to the extent
         that such Net Proceeds have not been used pursuant to clause (c)(2) of
         the first paragraph of Section 4.11 to make a Restricted Payment;
         provided, however, that no such Indebtedness may be Incurred pursuant
         to this clause (xii) to the extent that such contributions to capital
         or issuance and sale of Qualified Equity Interests were previously
         included in the determination of Share Capital for purposes of
         Incurring Indebtedness under clause (v) above of this paragraph (b) of
         this covenant;

             (xiii)    in addition to the items referred to in clauses (i)
         through (xii) above, Indebtedness of the Company or any Restricted
         Group Member in an aggregate amount not to exceed $20.0 million at any
         time outstanding; and

              (xiv)    guarantees by the Company of any Indebtedness of any
         Restricted Group Member permitted to be Incurred by such Restricted
         Group Member under this paragraph (b).

                 (c)  For purposes of determining any particular amount of
Indebtedness under this covenant, guarantees, Liens or obligations with respect
to letters of credit supporting Indebtedness otherwise included in the
determination of such particular amount shall not be included; provided,
however, that the foregoing shall not in any way be deemed to limit the
provisions of Section 4.18.

                 (d)  For purposes of determining compliance with this
covenant, in the event that an item of Indebtedness may be Incurred through the
first paragraph of this covenant or by meeting the criteria of one or more of
the types of Indebtedness described in the second paragraph of this covenant
(or the definitions of the terms used therein), the Company, in its sole
discretion, may, at the time of such Incurrence, (i) classify such item of
Indebtedness under and comply with either of such paragraphs (or any of such
definitions), as applicable, (ii) classify and divide such item of Indebtedness
into more than one of such paragraphs (or definitions), as applicable, and
(iii) elect to comply with such paragraphs (or definitions), as applicable, in
any order.

                 (e)  Notwithstanding any other provision of this covenant, the
maximum amount of Indebtedness that the Company or a Restricted Group Member
may Incur pursuant to this covenant shall not be deemed





<PAGE>   43
                                      -37-


to be exceeded, with respect to any outstanding Indebtedness, due solely to the
result of fluctuations in the exchange rates of currencies.

SECTION 4.13.  Limitations on Restrictions Affecting Restricted Group Members.

                 The Company shall not, and shall not cause or permit any
Restricted Group Member to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any encumbrance or restriction on the
ability of any Restricted Group Member to (x) pay dividends or make any other
distributions to the Company or any other Restricted Group Member on its Equity
Interests or with respect to any other interest or participation in, or
measured by, its profits, or pay any Indebtedness owed to the Company or any
other Restricted Group Member, (y) make loans or advances to, or guarantee any
Indebtedness or other obligations of, the Company or any other Restricted Group
Member, or (z) transfer any of its properties or assets to the Company or any
other Restricted Group Member.

                 The foregoing shall not prohibit (a) any encumbrance or
restriction existing under or by reason of any agreement in effect on the Issue
Date, as any such agreement is in effect on such date or as thereafter amended
or supplemented but only if such encumbrance or restriction is no more
restrictive than that in the agreement being amended; (b) customary provisions
contained in an agreement that has been entered into for the sale or
disposition of all or substantially all of the Equity Interests or assets of a
Restricted Group Member; provided, however, that (x) such encumbrance or
restriction is applicable only to such Restricted Group Member (or the
applicable assets to be sold) and (y) such sale or disposition is made in
accordance with Section 4.16; (c) any encumbrance or restriction existing under
or by reason of applicable law; (d) customary provisions restricting subletting
or assignment of any lease governing any leasehold interest of any Restricted
Group Member; (e) covenants in purchase money obligations for property acquired
in the ordinary course of business restricting transfer of such property; (f)
covenants in security agreements securing Indebtedness of the Company or any
Restricted Group Member (to the extent that such Liens were otherwise incurred
in accordance with Section 4.15) that restrict the transfer of property subject
to such agreements; (g) any agreement or other instrument of a Person acquired
by the Company or any Restricted Group Member in existence at the time of such
acquisition, which encumbrance or restriction (x) is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or
the properties or assets of the Person so acquired, and (y) is not incurred in
connection with or in contemplation of such acquisition; (h) any encumbrance or
restriction contained in any agreement entered into after the Issue Date, so
long as such encumbrance or restriction is not materially more disadvantageous
to the Holders than the encumbrances and restrictions of the Company or any
Restricted Group Member in existence at the Issue Date; (i) any encumbrance or
restriction contained in any stockholders, joint venture or similar agreement,
so long as such encumbrance or restriction is not materially more
disadvantageous to the Holders than the encumbrances and restrictions contained
in comparable agreements entered into prior to the Issue Date by the Company or
a Restricted Group Member; (j) any encumbrance or restriction contained in any
Senior Credit Facility; or (k) any encumbrance or restriction contained in any
agreement entered into after the Issue Date for Indebtedness so long as (A)
such encumbrance or restriction is not more restrictive than that which is
customary in comparable financing agreements and (B) management of the Company
determines that such encumbrance or restriction will not materially impair the
Company's ability to make payments when due on the Securities.

                 Nothing contained in this covenant shall prevent the Company
or any Restricted Group Member from (i) creating, Incurring, assuming or
suffering to exist any Liens not prohibited by Section 4.15; or (ii)
restricting the sale or other disposition of property or assets of the Company
or any Restricted Group Member that secure Indebtedness of the Company or any
Restricted Group Member.

SECTION 4.14.  Designation of Unrestricted Group Members.

                 (a)  The Company may designate any Restricted Group Member as
an "Unrestricted Group Member" under this Indenture (a "Designation") only if:

Either (A):

                (i)    no Default or Event of Default shall have occurred and
         be continuing after giving effect to such Designation;

               (ii)    the Company would be permitted to make an Investment
         (other than a Permitted Investment) at the time of such Designation
         (assuming the effectiveness of such Designation) pursuant to Section
         4.11 in an amount (the "Designation Amount") equal to the Fair Market
         Value of the Equity Interests of such Restricted Group Member owned
         directly or indirectly by the Company on such date; and

              (iii)    if such Restricted Group Member is a Subsidiary of
         Hermes Europe, simultaneously with such Designation, Hermes Europe
         shall make a similar designation of such Subsidiary in accordance with
         the terms of the Hermes Europe Senior Notes Indenture; or

(B):

                 (i)  such Restricted Group Member is not in compliance with
         one or more covenants under this Indenture that it is required to
         comply with;

                 (ii)  the Company has used its diligent best efforts to
         procure compliance by such Restricted Group Member with the covenants
         of this Indenture that such Restricted Group Member is required to
         comply with;

                 (iii)  the Company has used its diligent best efforts to cure
         such noncompliance; and

                 (iv)  the aggregate sum of (x) the Fair Market Value of all
         Equity Interests owned directly or indirectly by the Company of all
         Restricted Group Members which have been the subject of a Designation
         pursuant to this clause (B) since the Issue Date and which Designation
         has not been the subject of a Revocation (each such Fair Market Value
         of the Equity Interests of any such Restricted Group Member to be the
         Fair Market Value thereof at the date of each such Designation) plus
         (y) the greater of (1) $0 and (2) the excess of the Fair Market Value
         at the date of Designation pursuant to this clause (B) of the Equity
         Interests of such Restricted Group Member owned directly or indirectly
         by the Company over the Fair Market Value at the date of Revocation of
         the status of such Restricted Group Member as an Unrestricted Group
         Member does not exceed $25.0 million (such sum, at any date, the
         "Designation Basket").

                 All Subsidiaries of Unrestricted Subsidiaries shall be
Unrestricted Group Members. On the Issue Date, the Company shall effect
Designations of each Subsidiary of Hermes Europe that Hermes Europe has
previously designated as an Unrestricted Subsidiary in accordance with terms of
the Hermes Europe Senior Notes Indenture.





<PAGE>   45
                                      -39-


                 The Company shall not, and shall not cause or permit any
Restricted Group Member to, directly or indirectly, at any time be liable for
any Indebtedness (other than any Senior Credit Facility) which provides that
the holder thereof may (upon notice, lapse of time or both) declare a default
thereon or cause the payment thereof to be accelerated or payable prior to its
final scheduled maturity upon the occurrence of a default with respect to any
Indebtedness of any Unrestricted Group Member.

                 (b)  The Company may revoke any Designation of a Subsidiary or
Affiliate as an Unrestricted Group Member (a "Revocation") only if:

                 (i)   no Default or Event of Default shall have occurred and
         be continuing at the time of and after giving effect to such
         Revocation;

                 (ii)  all Liens and Indebtedness of such Unrestricted Group
         Member outstanding immediately following such Revocation would, if
         Incurred at such time, have been permitted to be Incurred for all
         purposes of this Indenture; and

                 (iii) if such Subsidiary is a Subsidiary of Hermes Europe,
         simultaneously with such Revocation, Hermes Europe shall make a
         similar revocation with respect to such Subsidiary in accordance with
         the terms of the Hermes Europe Senior Notes Indenture.

                 All Designations and Revocations must be evidenced by
resolutions of the Board of Directors of the Company, delivered to the Trustee
certifying compliance with the foregoing provisions.

SECTION 4.15.  Limitation on Liens.

                 The Company shall not, and shall not cause or permit any
Restricted Group Member to, directly or indirectly, Incur or suffer to exist
any Lien (other than any Permitted Lien) of any kind against or upon any of
their respective properties or assets now owned or hereafter acquired, or any
proceeds, income or profits therefrom, unless contemporaneously therewith or
prior thereto, (i) in the case of any Lien securing an obligation that ranks
pari passu with the Securities, effective provision is made to secure the
Securities equally and ratably with or prior to such obligation with a Lien on
the same collateral and (ii) in the case of any Lien securing an obligation
that is subordinated in right of payment to the Securities, effective provision
is made to secure the Securities with a Lien on the same collateral that is
prior to the Lien securing such subordinated obligation, in each case, for so
long as such obligation is secured by such Lien.

SECTION 4.16.  Limitation on Asset Sales.

                 The Company shall not, and shall not cause or permit any
Restricted Group Member to, directly or indirectly, make any Asset Sale, unless
(x) the Company or such Restricted Group Member, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the assets sold or otherwise disposed of and (y) at least 75% of such
consideration consists of (i) cash or Cash Equivalents, (ii) Replacement
Assets, (iii) publicly traded Equity Interests of a Person; provided, however,
that the Company or such Restricted Group Member shall sell (a "Monetization
Sale"), for cash or Cash Equivalents, such Equity Interests to a third Person
(other than to the Company or a Restricted Group Member) at a price not less
than the Fair Market Value thereof within 425 days of the consummation of such
Asset Sale, or (iv) any combination of the foregoing clauses (i) through (iii).
The amount of any (x) Indebtedness (other than any Subordinated Indebtedness)
of the Company or any Restricted Group Member that is actually assumed by the
transferee in such Asset Sale and from which the Company and the Restricted
Group Members are fully released shall be deemed to





<PAGE>   46
                                      -40-


be cash for purposes of determining the percentage of cash consideration
received by the Company or such Restricted Group Member and (y) notes or other
similar obligations received by the Company or any Restricted Group Member from
such transferee that are converted, sold or exchanged within 365 days of the
related Asset Sale by the Company or any Restricted Group Member into cash
shall be deemed to be cash, in an amount equal to the net cash proceeds
realized upon such conversion, sale or exchange for purposes of determining the
percentage of cash consideration received by the Company or such Restricted
Group Member. Any Net Cash Proceeds from any Asset Sale or any Monetization
Sale that are not, within 425 days of the consummation of such Asset Sale or
Monetization Sale, (A) invested in Replacement Assets or (B) used to repay and
permanently reduce the commitments under Indebtedness of the Company or any
Restricted Group Member other than Subordinated Indebtedness or Indebtedness of
the Company (other than under the Senior Credit Facility) with a Weighted
Average Life to Maturity or stated final maturity longer than that of the
Securities shall constitute "Excess Proceeds" subject to disposition as
provided below.

                 Within 40 days after the aggregate amount of Excess Proceeds
equals or exceeds $10.0 million, the Company shall make an Offer to Purchase,
from all Holders, that aggregate principal amount of Securities as can be
purchased with the Security Portion of Excess Proceeds (as defined below) at a
price in cash equal to 100% of the outstanding principal amount thereof, plus
accrued and unpaid interest, if any, to any purchase date. To the extent that
the aggregate of the principal and accrued interest of Securities validly
tendered and not withdrawn pursuant to an Offer to Purchase is less than the
Excess Proceeds, the Company may use such surplus for general corporate
purposes. If the aggregate of the principal and accrued interest of Securities
validly tendered and not withdrawn by Holders thereof exceeds the amount of
Securities that can be purchased with the Security Portion of Excess Proceeds,
Securities to be purchased will be selected pro rata based on the aggregate
principal amount of Securities tendered by each Holder. Upon completion of an
Offer to Purchase, the amount of Excess Proceeds shall be reset to zero.

                 In the event that any other Indebtedness of the Company that
ranks pari passu with the Securities (the "Other Debt") requires an offer to
purchase to be made to repurchase such Other Debt upon the consummation of an
Asset Sale, the Company may apply the Excess Proceeds otherwise required to be
applied to an Offer to Purchase to offer to purchase such Other Debt and to an
Offer to Purchase so long as the amount of such Excess Proceeds applied to
purchase the Securities is not less than the Security Portion of Excess
Proceeds. With respect to any Excess Proceeds, the Company shall make the Offer
to Purchase in respect thereof at the same time as the analogous offer to
purchase is made pursuant to any Other Debt and the Purchase Date in respect
thereof shall be the same as the purchase date in respect thereof pursuant to
any Other Debt.

                 For purposes of this covenant, "Security Portion of Excess
Proceeds" means (1) if no Other Debt is being offered to be purchased, the
amount of the Excess Proceeds and (2) if Other Debt is being offered to be
purchased, the amount of the Excess Proceeds equal to the product of (x) the
Excess Proceeds and (y) a fraction the numerator of which is the aggregate
amount of all Securities tendered pursuant to the Offer to Purchase related to
such Excess Proceeds (the "Security Amount") and the denominator of which is
the sum of the Security Amount and the aggregate amount as of the relevant
purchase date of all Other Debt tendered and purchased pursuant to a concurrent
offer to purchase such Other Debt made at the time of such Offer to Purchase.

                 If and to the extent that the Excess Proceeds from any Asset
Sale of any Restricted Group Member cannot at such time be paid as a dividend
to the Company by virtue of the Hermes Europe Senior Note Indenture as in
effect on the issue date, such Excess Proceeds shall not be deemed to
constitute Excess Proceeds until such time as and to the extent that such
Excess Proceeds are permitted to be paid as a dividend thereunder.

                                      -41-


                 Notwithstanding the foregoing, to the extent that any or all
of the Net Cash Proceeds of any Asset Sale of assets based outside the United
States are prohibited or delayed by applicable local law from being repatriated
to the United States and such Net Cash Proceeds are not actually applied in
accordance with the foregoing paragraphs, the Company shall not be required to
apply the portion of such Net Cash Proceeds so affected but may permit the
applicable Restricted Group Members to retain such portion of the Net Cash
Proceeds so long as the applicable local law will not permit repatriation to
the United States (the Company hereby agreeing to cause the applicable
Restricted Group Member to promptly take all actions required by the applicable
local law to permit such repatriation) and once such repatriation of any such
affected Net Cash Proceeds is permitted under the applicable local law, such
repatriation will be immediately effected and such repatriated Net Cash
Proceeds will be applied in the manner set forth in this covenant as if the
Asset Sale had occurred on such date; provided, however, that to the extent
that the Company has determined in good faith that repatriation of any or all
of the Net Cash Proceeds of such Asset Sale would have a material adverse tax
cost consequence, the Net Cash Proceeds so affected may be retained by the
applicable Restricted Group Member for so long as such material adverse tax
cost event would continue.

                 In the event that the Company makes an Offer to Purchase the
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and
Rule 14e- 1 under, the Exchange Act, and any violation of the provisions of
this Indenture relating to such Offer to Purchase occurring as a result of such
compliance shall not be deemed a Default or an Event of Default.

SECTION 4.17.  Limitation on Transactions with Affiliates.

                 The Company shall not, and shall not cause or permit any
Restricted Group Member to, directly or indirectly, conduct any business or
enter into any transaction or series of related transactions with or for the
benefit of any Affiliate, any holder of 5% or more of any class of Equity
Interests of the Company or any Restricted Group Member or any officer,
director or employee of the Company or any Restricted Group Member (each, an
"Affiliate Transaction"), unless such Affiliate Transaction is on terms that
are no less favorable to the Company or such Restricted Group Member, as the
case may be, than could reasonably be obtained at such time in a comparable
transaction with an unaffiliated third party. For any such transaction that
involves value in excess of $5.0 million, the Company shall deliver to the
Trustee an officers' certificate stating that a majority of the Disinterested
Directors has determined that the transaction satisfies the above criteria and
shall evidence such a determination by a Board Resolution delivered to the
Trustee. For any such transaction that involves value in excess of $20.0
million, the Company shall also obtain a written opinion from an Independent
Financial Advisor to the effect that such transaction is fair, from a financial
point of view, to the Company or such Restricted Group Member, as the case may
be.

                 Notwithstanding the foregoing, the restrictions set forth in
this covenant shall not apply to (i) transactions between or among the Company
and one or more Restricted Group Members or between or among Restricted Group
Members; (ii) customary directors' fees, indemnification and similar
arrangements, employee salaries, bonuses or employment agreements, compensation
or employee benefit arrangements and incentive arrangements with any officer,
director or employee of the Company or any Restricted Group Member entered into
in the ordinary course of business (including customary benefits thereunder);
(iii) transactions pursuant to agreements in effect on the Issue Date, as such
agreements are in effect on the Issue Date or as thereafter amended or
supplemented in a manner not adverse to the Holders; (iv) loans and advances to
officers, directors and employees of the Company or any Restricted Group Member
for travel, entertainment, housing, moving and other relocation expenses, in
each case made in the ordinary course of business and consistent with past
business practices; (v) any transaction between the Company or any Restricted
Group Member, on the one hand, and any





<PAGE>   48
                                      -42-


Affiliate of the Company or any Restricted Group Member engaged primarily in a
Telecommunications Business, on the other hand, (x) in the ordinary course of
business and consistent with commercially reasonable practices or (y) approved
by a majority of the Disinterested Directors; and (vi) payment of dividends in
respect of Equity Interests of the Company or any Restricted Group Member
permitted under Section 4.11 above; and (vii) any transaction or series of
related transactions involving consideration or payments of less than $25,000.

SECTION 4.18.  Limitation on Issuances of Guarantees by Restricted Group
               Members.

                 The Company shall not cause or permit any Restricted Group
Member, directly or indirectly, to guarantee any Indebtedness of the Company
("Guaranteed Indebtedness") (other than any guarantee of the Senior Credit
Facility), unless (i) such Restricted Group Member simultaneously executes and
delivers a supplemental indenture to this Indenture pursuant to which such
Restricted Group Member guarantees (a "Guarantee") all of the Company's
obligations under the Securities and this Indenture and (ii) such Restricted
Group Member waives, and will not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against the Company or any other Restricted Group Member as
a result of any payment by such Restricted Group Member under its Guarantee. If
the Guaranteed Indebtedness is (A) pari passu with the Securities, then the
guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Guarantee or (B) subordinated to the Securities, then the
guarantee of such Guaranteed Indebtedness shall be subordinated to the
Guarantee at least to the extent that the Guaranteed Indebtedness is
subordinated to the Securities.

                 Any Guarantee by a Restricted Group Member shall provide by
its terms that it shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all of the Equity Interests of the Company or any
Restricted Group Member in, or all or substantially all the assets of, such
Restricted Group Member (which sale, exchange or transfer is made in accordance
with this Indenture) or (ii) the release or discharge of the guarantee which
resulted in the creation of such Guarantee, except a discharge or release by or
as a result of payment under such guarantee.

SECTION 4.19.  Limitation on the Issuance and Sale of Equity Interests of
               Restricted Group Members.

                 The Company shall not sell, and shall not cause or permit any
Restricted Group Member, directly or indirectly, to issue or sell, any Equity
Interests of any Restricted Group Member, except (i) to the Company or a
Restricted Group Member; (ii) issuances of director's qualifying shares or
sales to foreign nationals of shares of Equity Interests of a foreign
Restricted Group Member, to the extent required by applicable law; (iii) if,
immediately after giving effect to such issuance or sale, such Restricted Group
Member would no longer constitute a Restricted Group Member; provided, however,
any investment in such Person remaining after giving effect to such issuance or
sale would have been permitted to be made under Section 4.11 above, if made on
the date of such issuance or sale; (iv) issuances or other sales of common
stock (including options, warrants or other rights to purchase common stock) of
a Restricted Group Member; provided, however, the Net Cash Proceeds, if any, of
such sale are applied in accordance with Section 4.16 above; (v) issuances of
common stock for cash (including options, warrants or other rights to purchase
common stock) of a Restricted Group Member; provided, however, that the per
share price to the investor of each share of common stock sold in such issuance
shall not be less than the book value per share of such Restricted Group
Member's common stock prior to such issuance (after adjusting for the effect of
such issuance);(vi) issuances of Equity Interests pursuant to employee stock
option plans created in the ordinary course of business on ordinary business
terms; and (vii) issuances of Equity Interests by any Restricted Group Member
in a transaction in which the Company acquires at the same time sufficient
Equity Interests of such Restricted Group Member to at least maintain the same
percentage ownership interest it had prior to such transaction.

SECTION 4.20.  Limitations on Lines of Business.

                 The Company shall not, and shall not cause or permit any
Restricted Group Members to, directly or indirectly engage to any substantial
extent in any line or lines of business other than a Related Business.

SECTION 4.21.  Additional Amounts.

                 All payments made by the Company under or with respect to the
Securities will be made free and clear of and without withholding or deduction
for or on account of any present of future Taxes imposed or levied by or on
behalf of any Taxing Authority within any jurisdiction in which the Company is
organized or engaged in business for tax purposes, unless the Company is
required to withhold or deduct Taxes by law or by the interpretation or
administration thereof.  If the Company is required to withhold or deduct any
amount for or on account of Taxes imposed by a Taxing Authority within any
jurisdiction in which the Company is organized or engaged in business for tax
purposes, from any payment made under or with respect to the Securities, the
Company will pay such additional amounts ("Additional Amounts") as may be
necessary so that the net amount received by each holder of Securities
(including Additional Amounts) after such withholding or deduction will equal
the amount the holder would have received if such Taxes had not been withheld
or deducted; provided, however, that no Additional Amounts will be payable with
respect to any Tax that would not have been imposed, payable or due (i) but for
the existence of any present or former connection between the holder (or the
beneficial owner of, or person ultimately entitled to obtain an interest in,
such Securities) and the jurisdiction in which the Company is organized or
engaged in business for tax purposes other than the mere holding of the
Securities; (ii) but for the failure to satisfy any certification,
identification or other reporting requirements whether imposed by statute,
treaty, regulation or administrative practice, provided that the Company has
delivered a request to the holder to comply with such requirements at least 30
days prior to the date by which such compliance is required; (iii) if the
presentation of Securities (where presentation is required) for payment has
occurred within 30 days after the date such payment was due and payable or was
duly provided for, whichever is later; or (iv) if the beneficial owner of, or
person ultimately entitled to obtain an interest in, such Securities had been
the holder of the Securities and would not be entitled to the payment of
Additional Amounts (excluding the impact of the book-entry procedures described
in Section 2.15).  In addition, Additional Amounts will not be payable with
respect to any Tax which is payable otherwise than by withholding from payments
of, or in respect of principal of, or any interest on, the Securities.

SECTION 4.22.  Deposit of Funds with Escrow Agent.

                 (a)  On the Issue Date, the Company shall deposit with the
Escrow Agent funds that together with the proceeds from the investment thereof
will be sufficient to pay the first four scheduled interest payments on the
Securities (excluding any Additional Amounts or Additional Interest).  All
Escrow Collateral shall be held in the Escrow Account until permitted to be
disbursed pursuant to the Escrow Agreement and then shall be disbursed strictly
in accordance with the terms thereof.

                 (b)  Pending release of the Escrow Funds as provided in the
Escrow Agreement, the Escrow Funds will be invested in Cash Equivalents as
specifically directed in writing by the Company.  Any interest or other profit
resulting from such investment will be deposited in the Escrow Account.

be a corporation organized and validly existing under the laws of Bermuda, the
British Virgin Islands, Netherlands Antilles, Canada, any country which is a
member of the European Union or the United States of America or any State

Company) would be less than the Debt to Annualized Operating Cash Flow Ratio of
the Company immediately prior to such transaction.

                 For purposes of the foregoing, the transfer (by lease,
assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all the properties and assets of one or
more Restricted Group Members the Equity Interests of which constitutes all or
substantially all the properties and assets of the Company shall be deemed to

power of, the Company, and the Company shall be discharged from its Obligations
under the Securities, this Indenture and the Escrow Agreement.

                              DEFAULT AND REMEDIES

SECTION 6.01.  Events of Default.

                 The occurrence of any of the following will be an "Event of
Default" under this Indenture:

                 (a)  failure to pay principal of any Security when due;

                 (b)  failure to pay any interest on any Security when due,

         notice to the Company by the Trustee or Holders of at least 25% in
         aggregate principal amount of the outstanding Securities; provided,
         however, that a default or breach of a covenant or agreement arising
         from a Restricted Affiliate ceasing to observe any covenant applicable
         to it resulting from an Involuntary Event shall not constitute an
         Event of Default unless such Involuntary Event continues for 90 days;

                 (f)  there shall be, with respect to any issue or issues of
         Indebtedness of the Company or any Significant Restricted Group Member
         having an outstanding principal amount of $10.0 million or more in the
         aggregate for all such issues of all such Persons, whether such
         Indebtedness now exists or shall hereafter be created, (x) an event of
         default that has caused the holders thereof (or their representative)
         (I) to declare such Indebtedness to be due and payable prior to its
         scheduled maturity and such Indebtedness has not been discharged in
         full or such acceleration has not been rescinded or annulled within 45
         days following such acceleration and/or (II) to commence judicial
         proceedings to foreclose upon, or to exercise remedies under
         applicable law or applicable security documents to take ownership of,
         the property or assets securing such Indebtedness and/or (y) the
         failure to make a principal payment at the final fixed maturity and
         such defaulted payment shall not have been made, waived or extended
         within 45 days of such payment default;

                 (g)  the rendering of a final judgment or judgments (not
         covered by insurance) against the Company or any Significant
         Restricted Group Member in an amount of $10.0 million or more which
         remains undischarged or unstayed for a period of 60 consecutive days;

                 (h)  the Company or any Significant Restricted Group Member
         pursuant to or within the meaning of any Bankruptcy Law:

         generally as they become due,

                 (2)      commences a voluntary case or proceeding,





<PAGE>   52
                                      -46-



                 (3)      consents to the entry of an order for relief against
         it in an involuntary case or proceeding,

                 (4)      consents or acquiesces in the institution of a
         bankruptcy or insolvency proceeding against it,

                 (5)      consents to the appointment of a Custodian of it or
         for all or substantially all of its property, or

                 (6)      makes a general assignment for the benefit of its
         creditors, or any of them takes any action to authorize or effect any
         of the foregoing;

                 (i)  a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that:

                 (1)      is for relief against the Company or any Significant
         Restricted Group Member in an involuntary case or proceeding,

                 (2)      appoints a Custodian of the Company or any
         Significant Restricted Group Member or for all or substantially all of
         its property, or

                 (3)      orders the liquidation of the Company or any
         Significant Restricted Group Member, and in each case the order or
         decree remains unstayed and in effect for 60 days; provided, however,
         that if the entry of such order or decree is appealed and dismissed on
         appeal, then the Event of Default hereunder by reason of the entry of
         such order or decree shall be deemed to have been cured; or

                 (j)  the Company shall challenge the Lien on the Escrow
         Collateral under the Escrow Agreement prior to such time as the Escrow
         Collateral is to be released to the Company, or the Trustee (on behalf
         of the Holders) shall fail to have a first priority perfected security
         interest in Escrow Collateral.

                 The term "Bankruptcy Law" means Title 11, U.S. Code or any
similar Federal, state or foreign law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, sequestrator or
similar official under any Bankruptcy Law.

                 The Trustee shall, within 30 days after receiving actual
notice of any Default or Event of Default with respect to the Securities, give
the Holders notice of all uncured Defaults thereunder known to it; provided,
however, that, except in the case of an Event of Default in payment with
respect to the Securities or a Default or Event of Default in complying with
Section 5.01, the Trustee shall be protected in withholding such notice if and
so long as a committee of its Trust Officers in good faith determines that the
withholding of such notice is in the interest of the Holders.

SECTION 6.02.  Acceleration.

                 If an Event of Default with respect to the Securities (other
than an Event of Default specified in clause (h) or (i) of Section 6.01 with
respect to the Company) occurs and is continuing, the Trustee or the Holders of
at least 25% in aggregate principal amount of the outstanding Securities by
notice in writing to the Company may declare the unpaid principal of (and
premium, if any) and accrued interest to the date of acceleration on all the
outstanding Securities to be due and payable immediately and, upon any such
declaration, such





<PAGE>   53
                                      -47-


principal amount (and premium, if any) and accrued interest, notwithstanding
anything contained in this Indenture or the Securities to the contrary, will
become immediately due and payable.

                 If an Event of Default specified in clause (h) or (i) of
Section 6.01 with respect to the Company occurs, all unpaid principal of and
accrued interest on all outstanding Securities shall ipso facto become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

                 After a declaration of acceleration, but before a judgment or
decree of the money due in respect of the Securities has been obtained, the
Holders of not less than a majority in aggregate principal amount of the
Securities then outstanding by written notice to the Trustee may rescind an
acceleration and its consequences if all existing Events of Default (other than
the nonpayment of principal of and interest on the Securities which has become
due solely by virtue of such acceleration) have been cured or waived and if the
rescission would not conflict with any judgment or decree. No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

                 No Holder will have any right to institute any proceeding with
respect to this Indenture or for any remedy thereunder, unless the Trustee (i)
shall have failed to act for a period of 60 days after receiving written notice
of a continuing Event of Default by such Holder and a request to act by Holders
of at least 25% in aggregate principal amount at maturity of Securities
outstanding, (ii) shall have been offered indemnity reasonably satisfactory to
it and (iii) shall not have received from the Holders of a majority in
aggregate principal amount at maturity of the outstanding Securities a
direction inconsistent with such request. However, such limitations do not
apply to a suit instituted by a Holder of any Security for enforcement of
payment of the principal of or interest on such Security on or after the due
date therefor (after giving effect to the grace period specified in clause (b)
of the first paragraph of this Article Six).

SECTION 6.03.  Other Remedies.

                 If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect
the payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities, this Indenture or the Escrow
Agreement.

                 The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy maturing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative to the extent permitted by law.

                 Upon a declaration of acceleration of the Securities in
accordance with Section 6.02, the Trustee shall foreclose on all Escrow
Collateral and take all other actions permitted of a secured party under the
UCC or otherwise.

SECTION 6.04.  Waiver of Past Default.

                 Subject to Sections 2.09, 6.07 and 9.02, prior to the
declaration of acceleration of the Securities, the Holders of not less than a
majority in aggregate principal amount of the outstanding Securities by written
notice to the Trustee may waive an existing Default and its consequences,
except a Default in the payment of principal of or interest on any Security as
specified in Section 6.01(a), (b) or (c) or a Default in respect of any term or
provision of this Indenture that may not be amended or modified without the
consent of each Holder





<PAGE>   54
                                      -48-


affected as provided in Section 9.02. The Company shall deliver to the Trustee
an Officers' Certificate stating that the requisite percentage of Holders have
consented to such waiver and attaching copies of such consents. In case of any
such waiver, the Company, the Trustee and the Holders shall be restored to
their former positions and rights hereunder and under the Securities,
respectively. This paragraph of this Section 6.04 shall be in lieu of Section
316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby
expressly excluded from this Indenture and the Securities, as permitted by the
TIA.

                 Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured and not to have occurred
for every purpose of this Indenture and the Securities, but no such waiver
shall extend to any subsequent or other Default or impair any right consequent
thereon.

SECTION 6.05.  Control by Majority.

                 Subject to Section 2.09, the Holders of a majority in
principal amount of the outstanding Securities may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on it.  However, the Trustee may refuse
to follow any direction that conflicts with law, this Indenture or the Escrow
Agreement, that the Trustee determines may be unduly prejudicial to the rights
of another Securityholder, or that may involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction. In the
event the Trustee takes any action or follows any direction pursuant to this
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against any loss or expense caused by taking such action
or following such direction. This Section 6.05 shall be in lieu of Section
316(a)(1)(A) of the TIA, and such Section 316(a)(1)(A) of the TIA is hereby
expressly excluded from this Indenture and the Securities, as permitted by the
TIA.

SECTION 6.06.  Limitation on Suits.

                 A Securityholder may not pursue any remedy with respect to
this Indenture or the Securities unless:

                (i)    the Holder gives to the Trustee written notice of a
         continuing Event of Default;

               (ii)    the Holders of at least 25% in aggregate principal
         amount of the outstanding Securities make a written request to the
         Trustee to pursue a remedy;

              (iii)    such Holder or Holders offer and, if requested, provide
         to the Trustee indemnity reasonably satisfactory to the Trustee
         against any loss, liability or expense;

               (iv)    the Trustee does not comply with the request within 60
         days after receipt of the request; and

                (v)    during such 60-day period the Holders of a majority in
         principal amount of the outstanding Securities (excluding Affiliates
         of the Company) do not give the Trustee a direction which, in the
         opinion of the Trustee, is inconsistent with the request.

                 A Securityholder may not use this Indenture to prejudice the
rights of another Securityholder or to obtain a preference or priority over
such other Securityholder.





<PAGE>   55
                                      -49-



SECTION 6.07.  Rights of Holders to Receive Payment.

                 Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of principal of or interest on a
Security, on or after the respective due dates therefor, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of the Holder.

SECTION 6.08.  Collection Suit by Trustee.

                 If an Event of Default in payment of principal or interest
specified in Section 6.01(a), (b) or (c) occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Company or any other obligor on the Securities for the whole amount of
principal and accrued interest remaining unpaid, together with interest overdue
on principal and to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per
annum borne by the Securities and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

SECTION 6.09.  Trustee May File Proofs of Claim.

                 The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Securityholders allowed in any judicial proceedings relative to the Company (or
any other obligor upon the Securities), its creditors or its property and shall
be entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same, and any
Custodian in any such judicial proceedings is hereby authorized by each
Securityholder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agent
and counsel, and any other amounts due the Trustee under Section 7.07. Nothing
herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Securityholder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Securityholder in any such proceeding.

SECTION 6.10.  Priorities.

                 If the Trustee collects any money or property pursuant to this
Article Six or the Escrow Agreement, it shall pay out the money or property in
the following order:

                 First: to the Trustee for amounts due under Section 7.07;

                 Second: to Holders for amounts due and unpaid on the
         Securities for principal and interest, ratably, without preference or
         priority of any kind, according to the amounts due and payable on the
         Securities for principal and interest, respectively; and

                 Third: to the Company.





<PAGE>   56
                                      -50-



                 The Trustee, upon prior written notice to the Company, may fix
a record date and payment date for any payment to Securityholders pursuant to
this Section 6.10.

SECTION 6.11.  Undertaking for Costs.

                 In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 shall not apply to a suit by the
Trustee, a suit by a Holder or group of Holders of more than 10% in aggregate
principal amount of the outstanding Securities, or to any suit instituted by
any Holder for the enforcement or the payment of the principal or interest on
any Securities on or after the respective due dates therefor.

                                 ARTICLE SEVEN

                                    TRUSTEE

SECTION 7.01.  Duties of Trustee.

                 (a)  If a Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

                 (b)  Except during the continuance of a Default:

                (1)    The Trustee shall not be liable except for the
         performance of such duties as are specifically set forth herein; and

                (2)    In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions conforming to the requirements of this Indenture or the
         Escrow Agreement; however, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine such certificates
         and opinions to determine whether or not they conform to the
         requirements of this Indenture or the Escrow Agreement.

                 (c)  The Trustee shall not be relieved from liability for its
own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                (1)    This paragraph does not limit the effect of paragraph
         (b) of this Section 7.01;

                (2)    The Trustee shall not be liable for any error of
         judgment made in good faith by a Trust Officer, unless it is proved
         that the Trustee was negligent in ascertaining the pertinent facts;
         and

                (3)    The Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05.





<PAGE>   57
                                      -51-



                 (d)  No provision of this Indenture or the Escrow Agreement
shall require the Trustee to expend or risk its own funds or otherwise incur
any financial liability in the performance of any of its duties hereunder or to
take or omit to take any action under this Indenture or take any action at the
request or direction of Holders if it shall have reasonable grounds for
believing that repayment of such funds is not assured to it or it does not
receive from such Holders an indemnity or security satisfactory to it in its
sole discretion against such risk, liability, loss, fee or expense which might
be incurred by it in compliance with such request or direction.

                 (e)  Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section
7.01.

                 (f)  The Trustee shall not be liable for interest on any money
received by it. Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

SECTION 7.02.  Rights of Trustee.

                 Subject to Section 7.01:

                 (a)  The Trustee shall conclusively rely on any document
believed by it to be genuine and to have been signed or presented by the proper
person. The Trustee need not investigate any fact or matter stated in the
document.

                 (b)  Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate and/or an Opinion of Counsel, which shall
conform to the provisions of Section 10.05. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on such
certificate or opinion.

                 (c)  The Trustee may act through attorneys and agents of its
selection and shall not be responsible for the misconduct or negligence of any
agent or attorney (other than an agent who is an employee of the Trustee)
appointed with due care.

                 (d)  The Trustee shall not be liable for any action it takes
or omits to take in good faith which it reasonably believes to be authorized or
within its rights or powers.

                 (e)  The Trustee may consult with counsel of its selection and
the advice or opinion of such counsel as to matters of law shall be full and
complete authorization and protection from liability in respect of any action
taken, omitted or suffered by it hereunder in good faith and in accordance with
the advice or opinion of such counsel.

                 (f)  Any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution.

                 (g)  The Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture or the Escrow Agreement
at the request or direction of any of the Securityholders pursuant to this
Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity satisfactory to the Trustee against the costs, expenses
and liabilities which might be incurred by it in compliance with such request
or direction.

                                      -52-



                 (h)  The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled
to examine the books, records and premises of the Company, personally or by
agent or attorney at the sole cost of the Company and shall incur no liability
or additional liability of any kind by reason of such inquiry or investigation.

                 (i)  The Trustee shall not be deemed to have notice of any
Event of Default unless a Trust Officer of the Trustee has actual knowledge
thereof or unless the Trustee shall have received written notice thereof at the
Corporate Trust Office of the Trustee, and such notice references the
Securities (including CUSIP Number) and this Indenture.

SECTION 7.03.  Individual Rights of Trustee.

                 The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company or
its Affiliates with the same rights it would have if it were not Trustee,
subject to Section 7.10 hereof. Any Agent may do the same with like rights.
However, the Trustee is subject to Sections 7.10 and 7.11.


SECTION 7.04.  Trustee's Disclaimer.

                 The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, the Escrow
Agreement or the Securities, it shall not be accountable for the Company's use
of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or any document issued in connection
with the sale of Securities or any statement in the Securities other than the
Trustee's certificate of authentication.

SECTION 7.05.  Notice of Defaults.

                 If a Default occurs and is continuing and the Trustee actually
knows of such Default, the Trustee shall mail to each Securityholder notice of
the Default within 30 days after the occurrence thereof. Except in the case of
a Default in payment of principal of or interest on any Security or a Default
in complying with any of the provisions of the Escrow Agreement, the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interest of
Securityholders. This Section 7.05 shall be in lieu of the proviso to Section
315(b) of the TIA and such proviso to Section 315(b) of the TIA is hereby
expressly excluded from this Indenture and the Securities, as permitted by the
TIA.

SECTION 7.06.  Reports by Trustee to Holders.

                 If required by TIA Section 313(a), within 60 days after each
September 1 beginning with September 1, 1998, the Trustee shall mail to each
Securityholder a report dated as of such September 1 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Section 313(b), (c) and
(d).

                 A copy of each such report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange, if any, on
which the Securities are listed.





<PAGE>   59
                                      -53-


                 The Company shall promptly notify the Trustee in writing if
the Securities become listed on any stock exchange or of any delisting thereof.

SECTION 7.07.  Compensation and Indemnity.

                 The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for its services. The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable disbursements, expenses
and advances (including fees, disbursements and expenses of its agents and
counsel) incurred or made by it in addition to the compensation for its
services except any such disbursements, expenses and advances as may be
attributable to the Trustee's negligence or bad faith. Such expenses shall
include the reasonable compensation, disbursements and expenses of the
Trustee's agents, accountants, experts and counsel and any taxes or other
expenses incurred by a trust created pursuant to Section 8.01 hereof.

                 The Company shall indemnify the Trustee, its agents and
officers, for, and hold it harmless against any and all loss, damage, claims,
liability or expense, including taxes (other than franchise taxes imposed on
the Trustee and taxes based upon, measured by or determined by the income of
the Trustee), arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent that such loss, damage, claim, liability or expense is due to its
own negligence or bad faith. The Trustee shall notify the Company promptly of
any claim asserted against the Trustee for which it may seek indemnity.
However, the failure by the Trustee to so notify the Company shall not relieve
the Company of its obligations hereunder.  The Company shall defend the claim
and the Trustee shall cooperate in the defense (and may employ its own counsel)
at the Company's expense; provided, however, that the Company's reimbursement
obligation with respect to counsel employed by the Trustee will be limited to
the reasonable fees and expenses of such counsel.

                 The Company need not pay for any settlement made without its
written consent, which consent shall not be unreasonably withheld. The Company
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee as a result of the material violation of this Indenture
by the Trustee.

                 To secure the Company's payment obligations in this Section
7.07, the Trustee shall have a Lien prior to the Securities against all money
or property held or collected by the Trustee, in its capacity as Trustee,
except money or property held in trust to pay principal of or interest on
particular Securities or the Purchase Price or redemption price of any
Securities to be purchased or pursuant to an Offer to Purchase or redeemed.

                 When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(h) or (i) occurs, the expenses
(including the reasonable fees and expenses of its agents and counsel) and the
compensation for the services shall be preferred over the status of the Holders
in a proceeding under any Bankruptcy Law and are intended to constitute
expenses of administration under any Bankruptcy Law. The Company's obligations
under this Section 7.07 and any claim arising hereunder shall survive the
resignation or removal of any Trustee, the discharge of the Company's
obligations pursuant to Article Eight and any rejection or termination under
any Bankruptcy Law, and the termination of this Indenture.

                                      -54-



SECTION 7.08.  Replacement of Trustee.

                 The Trustee may resign at any time by so notifying the Company
in writing. The Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Trustee and the Company
in writing and may appoint a successor Trustee with the Company's consent. The
Company may at any time, other than during the existence of a Default or an
Event of Default, remove the Trustee by Company Order given at least 30 days
prior to the date of the proposed removal.

                 If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office,
the Holders of a majority in principal amount of the Securities may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

                 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. As promptly as
practicable after that, the retiring Trustee shall transfer, after payment of
all sums then owing to the Trustee pursuant to Section 7.07, all property held
by it as Trustee to the successor Trustee, subject to the Lien provided in
Section 7.07, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have the rights, powers and duties
of the Trustee under this Indenture. A successor Trustee shall mail notice of
its succession to each Securityholder.

                 If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in principal amount of the outstanding
Securities may petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor Trustee.

                 If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

                 Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

SECTION 7.09.  Successor Trustee by Merger, etc.

                 If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation or banking corporation, the resulting, surviving or transferee
corporation or banking corporation without any further act shall be the
successor Trustee.

SECTION 7.10.  Eligibility; Disqualification.

                 This Indenture shall always have a Trustee which shall be
 eligible to act as Trustee under TIA Sections 310(a)(1) and 310(a)(2). The
 Trustee shall have a combined capital and surplus of at least $50,000,000 as
 set forth in
its most recent published annual report of condition. If the Trustee has or
shall acquire any "conflicting interest" within the meaning of TIA Section
310(b), the Trustee and the Company shall comply with the provisions of TIA
Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which
other securities or certificates of interest or participation in other
securities of the Company are outstanding if the requirements for such
exclusion set forth in TIA Section 310(b)(1) are met. If at





<PAGE>   61
                                      -55-


any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.10, the Trustee shall resign immediately in the
manner and with the effect hereinbefore specified in this Article Seven.

SECTION 7.11.  Preferential Collection of Claims Against Company.

                 The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein.

SECTION 7.12.  Trustee's Application for Instructions from the Company.

                 Any  application by the Trustee for written instructions from
the Company may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the
date on and/or after which such action shall be taken or such omission shall be
effective.  The Trustee shall not be liable for any action taken by, or
omission of, the Trustee in accordance with a proposal included in such
application on or after the date specified in such application (which date
shall not be less than three Business Days after the date any officer of the
Company actually receives such application, unless any such officer shall have
consented in writing to any earlier date) unless prior to taking any such
action (or the effective date in the case of an omission), the Trustee shall
have received written instructions in response to such application specifying
the action to be taken or omitted.

                                 ARTICLE EIGHT

                             DISCHARGE OF INDENTURE

SECTION 8.01.  Termination of Company's Obligations.

                 The Company may terminate its substantive obligations in
respect of the Securities by delivering all outstanding Securities to the
Trustee for cancellation and paying all sums payable by it on account of
principal of and interest on all Securities or otherwise. In addition to the
foregoing, the Company may terminate its obligation under Sections 4.04, 4.06,
4.08, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 (and
no Default with respect to such Sections under Section 6.01(c) shall thereafter
apply), by (i) depositing with the Trustee, under the terms of an irrevocable
trust agreement, money or U. S. Government Obligations sufficient (without
reinvestment) to pay all remaining indebtedness on the Securities at maturity
or upon earlier redemption, (ii) delivering to the Trustee either an Opinion of
Counsel or a ruling directed to the Trustee from the Internal Revenue Service
to the effect that the Holders of the Securities will not recognize income,
gain or loss for federal income tax purposes as a result of such deposit and
termination of obligations, (iii) delivering to the Trustee an Opinion of
Counsel to the effect that the Company's exercise of its option under this
paragraph will not result in any of the Company, the Trustee or the trust
created by the Company's deposit of funds pursuant to this provision becoming
or being deemed to be an "investment company" under the Investment Company Act
of 1940, as amended (the "Investment Company Act"), and (iv) delivering to the
Trustee an Officers' Certificate and an Opinion of Counsel each stating
compliance with all conditions precedent provided for herein. In addition, the
Company may, provided that no Default or Event of Default has occurred and is
continuing or would arise therefrom (or, with respect to a Default specified in
Section 6.01(h) or (i), occurs at any time on or prior to the 91st calendar day
after the date of such deposit (it being understood that this condition shall
not be deemed satisfied until after such 91st day)), terminate all of its
substantive obligations in respect of the Securities (including





<PAGE>   62
                                      -56-


its obligations to pay the principal of and interest on the Securities) by (i)
depositing with the Trustee, under the terms of an irrevocable trust agreement,
money or U.S. Government Obligations sufficient (without reinvestment) to pay
all remaining indebtedness on the Securities at maturity or upon earlier
redemption, (ii) delivering to the Trustee either a ruling directed to the
Trustee from the Internal Revenue Service to the effect that the Holders of the
Securities will not recognize income, gain or loss for federal income tax
purposes as a result of such deposit and termination of obligations or an
Opinion of Counsel addressed to the Trustee based upon such a ruling or based
on a change in the applicable Federal tax law since the date of this Indenture
to such effect, (iii) delivering to the Trustee an Opinion of Counsel to the
effect that the Company's exercise of its option under this paragraph will not
result in any of the Company, the Trustee or the trust created by the Company's
deposit of funds pursuant to this provision becoming or being deemed to be an
"investment company" under the Investment Company Act and (iv) delivering to
the Trustee an Officers' Certificate and an Opinion of Counsel each stating
compliance with all conditions precedent provided for herein.

                 Notwithstanding the foregoing paragraph, the Company's
obligations under Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.10, 2.12, 2.13
and 4.01 (but not with respect to termination of substantive obligations
pursuant to the third sentence of the foregoing paragraph), 4.02, 7.07, 7.08,
8.03 and 8.04 shall survive until the Securities are no longer outstanding.
Thereafter the Company's obligations in Sections 7.07, 8.03 and 8.04 shall
survive.

                 After such delivery or irrevocable deposit and delivery of an
Officers' Certificate and Opinion of Counsel, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture except for those surviving obligations specified
above.

                 The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U. S. Government
Obligations deposited pursuant to this Section 8.01 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of outstanding
Securities.

SECTION 8.02.  Application of Trust Money.

                 The Trustee shall hold in trust money or U. S. Government
Obligations deposited with it pursuant to Section 8.01, and shall apply the
deposited money and the money from United States Government Obligations in
accordance with this Indenture solely to the payment of principal of and
interest on the Securities.

SECTION 8.03.  Repayment to Company.

                 Subject to Sections 7.07 and 8.01, the Trustee shall promptly
pay to the Company upon written request any excess money held by it at any
time. The Trustee shall pay to the Company upon written request any money held
by it for the payment of principal or interest that remains unclaimed for two
years; provided, however, that the Trustee before being required to make any
payment may at the expense of the Company cause to be published once in a
newspaper of general circulation in The City of New York or mail to each Holder
entitled to such money notice that such money remains unclaimed and that, after
a date specified therein which shall be at least 30 days from the date of such
publication or mailing, any unclaimed balance of such money then remaining
shall be repaid to the Company. After payment to the Company, Securityholders
entitled to money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another person and all
liability of the Trustee or Paying Agent with respect to such money shall
thereupon cease.

SECTION 8.04.  Reinstatement.

                 If the Trustee is unable to apply any money or U.S. Government
Obligations in accordance with Section 8.01 by reason of any legal proceeding
or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01 until
such time as the Trustee is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 8.01; provided, however, that
if the Company has made any payment of interest on or principal of any
Securities because of the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee.

                                  ARTICLE NINE

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.  Without Consent of Holders.

                 The Company, when authorized by a resolution of its Board of
Directors, and the Trustee may amend or supplement this Indenture or the
Securities without notice to or consent of any Securityholder:

                (i)    to cure any ambiguity, defect or inconsistency;
         provided, however, that such amendment or supplement does not
         materially adversely affect the rights of any Holder;

               (ii)    to effect the assumption by a successor Person of all
         obligations of the Company under the Securities, this Indenture and
         the Escrow Agreement in connection with any transaction complying with
         Article Five of this Indenture;

              (iii)    to provide for uncertificated Securities in addition to
         or in place of certificated Securities;

               (iv)    to comply with any requirements of the SEC in order to
         effect or maintain the qualification of this Indenture under the TIA;

                (v)    to make any change that would provide any additional
         benefit or rights to the Holders;

               (vi)    to make any other change that does not materially
         adversely affect the rights of any Holder under this Indenture;

              (vii)    to add to the covenants of the Company for the benefit
         of the Holders, or to surrender any right or power herein conferred
         upon the Company; or

             (viii)    to secure the Securities pursuant to the requirements of
         Section 4.15 or otherwise;

provided, however, that the Company has delivered to the Trustee an Opinion of
Counsel stating that such amendment or supplement complies with the provisions
of this Section 9.01.

                                      -58-



SECTION 9.02.  With Consent of Holders.

                 Subject to Section 6.07, the Company, when authorized by a
resolution of its Board of Directors, and the Trustee may amend or supplement
this Indenture or the Securities with the written consent of the Holders of a
majority in principal amount of the outstanding Securities. Subject to Section
6.07, the Holders of a majority in principal amount of the outstanding
Securities may waive compliance by the Company with any provision of this
Indenture or the Securities. However, without the consent of the Holder of each
Security affected, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not:

                (1)    change the maturity of the principal of any such
         Security;

                (2)    alter the optional redemption or repurchase provisions
         of any such Security or this Indenture in a manner adverse to the
         Holders of such Security;

                (3)    reduce the principal amount of any such Security;

                (4)    reduce the rate of or extend the time for payment of

         of or interest on any such Security;

                (6)    modify any provisions of Section 6.04 (other than to add
         sections of this Indenture or the Securities subject thereto) or 6.07
         or this Section 9.02 (other than to add sections of this Indenture or
         the Securities which may not be amended, supplemented or waived
         without the consent of each Securityholder affected);

                (7)    reduce the percentage of the principal amount of
         outstanding Securities necessary for amendment to or waiver of
         compliance with any provision of this Indenture or the Securities or
         for waiver of any Default in respect thereof;

                (8)    waive a default in the payment of the principal of or
         interest on or redemption payment with respect to any such Security
         (except a rescission of acceleration of the Securities by the Holders
         as provided in Section 6.02 and a waiver of the payment default that
         resulted from such acceleration);

                (9)    modify the ranking or priority of such Security;

               (10)    modify the provisions of any covenant (or the related
         definitions in this Indenture) requiring the Company to make any Offer
         to Purchase in a manner materially adverse to the Holders; or

               (11)    modify the provisions of the Escrow Agreement or this
         Indenture relating to the Escrow Collateral or release the Escrow
         Collateral from the Lien under the Escrow Agreement or permit any
         other obligation to be secured by the Escrow Collateral.

                 It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.





<PAGE>   65
                                      -59-



                 After an amendment, supplement or waiver under this Section
9.02 becomes effective, the Company shall mail to the Holders affected thereby
a notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03.  Compliance with Trust Indenture Act.

                 Every amendment to or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.

SECTION 9.04.  Revocation and Effect of Consents.

                 Until an amendment or waiver becomes effective, a consent to
it by a Holder is a continuing consent by the Holder and every subsequent
Holder of that Security or portion of that Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is
not made on any Security. Subject to the following paragraph, any such Holder
or subsequent Holder may revoke the consent as to such Holder's Security or
portion of such Security by notice to the Trustee or the Company received
before the date on which the Trustee receives an Officers' Certificate
certifying that the Holders of the requisite principal amount of Securities
have consented (and not theretofore revoked such consent) to the amendment,
supplement or waiver.

                 The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders of Securities entitled to
consent to any amendment, supplement or waiver. If a record date is fixed,
then, notwithstanding the last sentence of the immediately preceding paragraph,
those persons who were Holders of Securities at such record date (or their duly
designated proxies), and only those persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such persons continue to be Holders of such Securities after
such record date. No such consent shall be valid or effective for more than 90
days after such record date.

                 After an amendment, supplement or waiver becomes effective, it
shall bind every Securityholder, unless it makes a change described in any of
clauses (1) through (11) of Section 9.02. In that case the amendment,
supplement or waiver shall bind each Holder of a Security who has consented to
it and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security.

SECTION 9.05.  Notation on or Exchange of Securities.

                 If an amendment, supplement or waiver changes the terms of a
Security, the Trustee may require the Holder of the Security to deliver it to
the Trustee. The Trustee may place an appropriate notation on the Security
about the changed terms and return it to the Holder. Alternatively, if the
Company or the Trustee so determines, the Company in exchange for the Security
shall issue and the Trustee shall authenticate a new Security that reflects the
changed terms. Failure to make the appropriate notation or issue a new Security
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06.  Trustee to Sign Amendments, etc.

                 The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this





<PAGE>   66
                                      -60-


Article Nine is authorized or permitted by this Indenture and that such
amendment, supplement or waiver constitutes the legal, valid and binding
obligation of the Company, enforceable in accordance with its terms (subject to
customary exceptions). The Trustee may, but shall not be obligated to, execute
any such amendment, supplement or waiver which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise. In signing any
amendment, supplement or waiver, the Trustee shall be entitled to receive an
indemnity reasonably satisfactory to it.

SECTION 11.01.  Escrow Agreement.

                 The due and punctual payment of the first four scheduled
interest payments on the Securities when and as the same shall be due and
payable on an Interest Payment Date or by acceleration shall be secured as
provided in the Escrow Agreement which the Company and the Trustee have entered
into simultaneously with the execution of this Indenture.  Upon the
acceleration of the maturity of the Securities, the Trustee shall foreclose
upon the Escrow Collateral.  Each Holder of Securities, by its acceptance
thereof, consents and agrees to the terms of the Escrow Agreement (including,
without limitation, the provisions providing for foreclosure and disbursement
of Escrow Collateral) as the same may be in effect or may be amended from time
to time in accordance with its terms and the terms hereof and authorizes and
directs the Escrow Agent and the Trustee to enter into the Escrow Agreement and
to perform its obligations and exercise its rights thereunder in accordance
therewith.  The Trustee is hereby empowered and directed to act as secured
party hereunder and under the Escrow Agreement for the benefit of the Holders.
The Company shall deliver to the Trustee copies of the Escrow Agreement, and
shall do or cause to be done all such acts and things as may be necessary or
proper, or as may be required by the provisions of the Escrow Agreement, to
assure and confirm to the Trustee the security interest in the Escrow
Collateral contemplated by the Escrow Agreement or any part thereof, as from
time to time constituted, so as to render the same available for the security
and benefit of this Indenture with respect to, and of, the Securities,
according to the intent and purposes expressed in the Escrow Agreement.  The
Company shall take any and all actions reasonably required to cause the Escrow
Agreement to create and maintain (to the extent possible under applicable law),
as security for the obligations of the Company hereunder, a first priority and
exclusive security interest in and on all the Escrow Collateral, in favor of
the Trustee for the benefit of the Holders of Securities, superior to and prior
to the rights of all third Persons and subject to no other Liens.  The Trustee
shall have no responsibility for perfecting or maintaining the perfection of
the Trustee's security interest in the Escrow Collateral or for filing any
instrument, document or notice in any public office at any time or times.

                 (a)  The Company shall furnish to the Trustee simultaneously
with the execution and delivery of this Indenture an Opinion of Counsel either
(i) stating that in the opinion of such counsel all action has been taken with
respect to the recording, registering and filing of this Indenture, financing
statements or other instruments necessary to make effective the security
interest intended to be created by the Escrow Agreement and reciting the
details of such action, or (ii) stating that in the opinion of such counsel no
such action is necessary to make such security interest effective.

                 (b)  The Company shall furnish to the Trustee on each
anniversary of the Issue Date (upon receipt of written notice from Escrow
Agent) until the date upon which the balance of Escrow Funds shall have been
reduced to zero, an Opinion of Counsel, dated as of such date, either (i)
stating that (A) in the opinion of such counsel, action has been taken with
respect to the recording, registering, filing, re-recording, re-registering and
refiling of all supplemental indentures, financing statements, continuation
statements or other instruments of further assurance as is necessary to
maintain the Lien of the Escrow Agreement and reciting the details of such
action or referring to prior Opinions of Counsel in which such details are
given and (B) based on relevant laws as in effect on the date of such Opinion
of Counsel, all financing statements and continuation statements have been
executed and filed that are necessary as of such date and during the succeeding
12 months fully to preserve and protect, to the extent such protection and
preservation are possible by filing, the rights of the Holders of Securities
and the Trustee hereunder and under the Escrow Agreement with respect to the
security interests in the Escrow Collateral or (ii) stating that, in the
opinion of such counsel, no such action is necessary to maintain such Lien and
assignment.

SECTION 11.03.  Release of Escrow Collateral.

                 (a)  Subject to subsections (b), (c) and (d) of this Section
11.03, the Escrow Collateral may be released from the security interest created
by the Escrow Agreement only in accordance with the provisions of the Escrow
Agreement.

                 (b)  Except to the extent that any security interest on
proceeds of Escrow Collateral is automatically released by operation of Section
9-306 of the Uniform Commercial Code or other similar law, no Escrow Collateral
shall be released from the security interest created by the Escrow Agreement
pursuant to the provisions of the Escrow Agreement, other than to the Holders
pursuant to the terms thereof.

                 (c)  At any time when an Event of Default shall have occurred
and be continuing and the maturity of the Securities shall have been
accelerated (whether by declaration or otherwise), no Escrow Collateral shall
be released pursuant to the provisions of the Escrow Agreement, and no release
of Escrow Collateral in contravention of this Section 11.03(c) shall be
effective as against the Holders of Securities, except for the disbursement of
all Escrow Funds (as defined in the Escrow Agreement) and other Escrow
Collateral to the Trustee pursuant to Section 6(c) of the Escrow Agreement.

                 (d)  The release of any Escrow Collateral from the security
interests created by this Indenture and the Escrow Agreement shall not be
deemed to impair the security under this Indenture in contravention of the
provisions hereof if and to the extent the Escrow Collateral is released
pursuant to the terms hereof or pursuant to the terms of the Escrow Agreement.
To the extent applicable, the Company shall cause TIA Section 314(d) relating
to the release of property or securities from the security interest of the
Escrow Agreement to be complied with.  Any certificate or opinion required by
TIA Section 314(d) may be made by an Officer of the Company except in cases
where TIA Section 314(d) requires that such certificate or opinion be made by
an independent Person, which





<PAGE>   71
                                      -65-


Person shall be an independent engineer, appraiser or other expert selected or

                Escrow Agreement.

                 Subject to the provisions of Section 7.01 and Section 7.02,
the Trustee may, without the consent of the Holders of Securities, on behalf of
the Holders of Securities, take all actions it deems necessary or appropriate
in order to (a) enforce any of the terms of the Escrow Agreement and (b)
collect and receive any and all amounts payable in respect of the obligations
of the Company hereunder.  The Trustee shall have power to institute and
maintain such suits and proceedings as it may deem expedient to prevent any
impairment of the Escrow Collateral by any acts that may be unlawful or in
violation of the Escrow Agreement or this Indenture, and such suits and
proceedings as the Trustee may deem expedient to preserve or protect its
interests and the interests of the Holders of Securities in the Escrow
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or
order would impair the security interest hereunder or be prejudicial to the
interests of the Holders of Securities or of the Trustee).

SECTION 11.05.  Authorization of Receipt of Funds by the Trustee Under the
                Escrow Agreement.

                 The Trustee is authorized to receive any funds for the benefit
of the Holders of Securities disbursed under the Escrow Agreement, and to make
further distributions of such funds to the Holders of Securities according to
the provisions of this Indenture.

SECTION 11.06.  Termination of Security Interest.

                 Upon the earliest to occur of (i) the date upon which the

                             (REVERSE OF SECURITY)

                         GLOBAL TELESYSTEMS GROUP, INC.

                          9 7/8% Senior Note due 2005

1.       Interest.

                 GLOBAL TELESYSTEMS GROUP, INC., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Security
at the rate per annum shown above.  Cash interest on the Securities will accrue
from the most recent date to which interest has been paid or, if no interest
has been paid, from February 10, 1998.  The Company will pay interest
semi-annually in arrears on each Interest Payment Date, commencing August 15,
1998.  Interest will be computed on the basis of a 360-day year of twelve
30-day months.

                 The Company shall pay interest on overdue principal from time
to time on demand at the rate borne by the Securities and on overdue
installments of interest (without regard to any applicable grace periods) at
the rate borne by the Securities to the extent lawful.

2.       Method of Payment.

                 The Company shall pay interest on the Securities (except
defaulted interest) to the persons who are the registered Holders at the close
of business on the Interest Record Date immediately preceding the Interest
Payment Date even if the Securities are cancelled on registration of transfer
or registration of exchange after such Interest Record Date.  Holders must
surrender Securities to a Paying Agent to collect principal payments.  The
Company shall pay principal and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts
("U.S. Legal Tender").  However, the Company may pay principal and interest by
wire transfer of Federal funds (provided that the Paying Agent shall have
received wire instructions on or prior to the relevant Interest Record Date),
or interest by check payable in such U.S. Legal Tender.  The Company may
deliver any such interest payment to the Paying Agent or to a Holder at the
Holder's registered address.

3.       Paying Agent and Registrar.

                 Initially, The Bank of New York, a New York banking
corporation  (the "Trustee"), will act as Paying Agent and Registrar in the
Borough of Manhattan, The City of New York.  The Company may change any Paying
Agent or Registrar without notice to the Holders.  The Company or any of its
Subsidiaries may, subject to certain exceptions, act as Registrar.

4.       Indenture.

                 The Company issued the Securities under an Indenture, dated as
of February 10, 1998 (the "Indenture"), among the Company, Global TeleSystems
Group, Inc. and the Trustee.  Capitalized terms herein are used as defined in
this Indenture unless otherwise defined herein.  The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections  77aaa-77bbbb)
(the "TIA"), as in effect on the date of the Indenture until such time as the
Indenture is




                                     A-3
<PAGE>   76

qualified under the TIA, and thereafter as in effect on the date on which the
Indenture is qualified under the TIA.  Notwithstanding anything to the contrary
herein, the Securities are subject to all such terms, and holders of Securities
are referred to the Indenture and the TIA for a statement of them.  This is one
of the Securities referred to in the Indenture.  The Securities referred to in
the Indenture are general obligations of the Company limited in aggregate
principal amount to $105,000,000.

5.       Optional Redemption.

         (a)  The Securities will be redeemable at the option of the Company,
in whole or in part, at any time or from time to time, on or after February 15,
2002 at the redemption prices (expressed as a percentage of principal amount)
set forth below, plus accrued and unpaid interest thereon, if any, to the
redemption date if redeemed during the twelve- month period commencing on

         (b)  Redemption Upon Public Equity Offering or Strategic Equity
Investment.

                 At any time, or from time to time, prior to February 15, 2001,
the Company may redeem up to one-third of the original aggregate principal
amount of the Securities at a redemption price equal to 109.875% of the
principal amount of the Securities so redeemed, plus accrued and unpaid
interest thereon, if any, to the redemption date, with the net cash proceeds of
one or more Public Equity Offerings or Strategic Equity Investments resulting
in aggregate gross proceeds to the Company of at least $75.0 million; provided,
however, that at least two-thirds of the principal amount of Securities
originally issued would remain outstanding immediately after giving effect to
any such redemption (excluding any Securities owned by the Company or any of
its Affiliates).

6.       Notice of Redemption.

                 Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Securities to be redeemed at its registered address; provided,
however, that notice of redemption pursuant to paragraph 5(b) of this Security
will be mailed to each Holder of Securities to be redeemed no later than 60
days following the consummation of the last Public Equity Offering resulting in
gross cash proceeds to the Company, when aggregated with all prior Public
Equity Offerings, of at least $75.0 million.  The Trustee may select for
redemption portions of the principal amount of Securities that have
denominations equal to or larger than $1,000 principal amount.  Securities and
portions of them the Trustee so selects shall be in amounts of $1,000 principal
amount or integral multiples thereof.

                 If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed.  A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the
Holder thereof upon cancellation of the original Security.  On and after the
Redemption Date, interest will cease to accrue on Securities or




                                     A-4
<PAGE>   77


portions thereof called for redemption so long as the Company has deposited
with the Paying Agent for the Securities funds in satisfaction of the
redemption price pursuant to this Indenture.

7.       Change of Control Offer.

                 Upon the occurrence of a Change of Control, the Company will
be required to offer to purchase all outstanding Securities at a purchase price
in cash equal to 101% of the aggregate principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the Purchase Date.

8.       Limitation on Disposition of Assets.

                 Upon the occurrence of certain Asset Sales, the Company is,
subject to certain conditions, obligated to make an offer to purchase
Securities at a purchase price in cash equal to 100% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon, if any, to the
Purchase Date.

9.       Denominations; Transfer; Exchange.

                 The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000.  A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture.  The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

10.      Persons Deemed Owners.

                 The registered Holder of a Security shall be treated as the
owner of it for all purposes.

11.      Unclaimed Funds.

                 If funds for the payment of principal or interest remain
unclaimed for two years, the Trustee and the Paying Agent will repay the funds
to the Company at its written request.  After that, all liability of the
Trustee and such Paying Agent with respect to such funds shall cease.

12.      Legal Defeasance and Covenant Defeasance.

                 The Company may be discharged from its obligations under the
Indenture and the Securities except for certain provisions thereof, and may be
discharged from obligations to comply with certain covenants contained in the
Indenture and the Securities, in each case upon satisfaction of certain
conditions specified in the Indenture.

13.      Amendment; Supplement; Waiver.

                 Subject to certain exceptions, the Indenture and the
Securities may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or compliance with any provision may
be waived with the consent of the Holders of a majority in aggregate principal
amount of the Securities then outstanding.  Without no-




                                     A-5
<PAGE>   78

tice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture and the Securities to, among other things, cure any ambiguity,
defect or inconsistency, provide for uncertificated Securities in addition to
or in place of certificated Securities, effect the assumption by a successor
person of all obligations of the Company under Securities, the Indenture and
the Escrow Agreement in connection with any transaction complying with Article
Five of the Indenture or comply with any requirements of the SEC in connection
with the qualification of the Indenture under the TIA, or make any other change
that does not materially adversely affect the rights of any Holder of a
Security.

14.      Restrictive Covenants.

                 The Indenture contains certain covenants that, among other
things, limit the ability of the Company and the Restricted Group Members to
make restricted payments, to incur indebtedness, to create liens, to sell
assets, to permit restrictions on dividends and other payments to become
applicable to Restricted Group Members, to consolidate, merge or sell all or
substantially all of its assets, to engage in transactions with affiliates or
certain other related persons.  The limitations are subject to a number of
important qualifications and exceptions.  The Company must annually report to
the Trustee on compliance with such limitations.

15.      Defaults and Remedies.

                 If an Event of Default (other than certain events of
bankruptcy, insolvency or reorganization affecting the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Securities then outstanding by notice in writing to the Company may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture.  If certain events of bankruptcy,
insolvency or reorganization affecting the Company occur under the Indenture,
the Securities will ipso facto become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder of
Securities.  Holders of Securities may not enforce the Indenture or the
Securities except as provided in this Indenture.  The Trustee is not obligated
to enforce the Indenture or the Securities unless it has received indemnity
reasonably satisfactory to it.  The Indenture permits, subject to certain
limitations therein provided, Holders of a majority in aggregate principal
amount of the Securities then outstanding to direct the Trustee in its exercise
of any trust or power.  The Trustee may withhold from Holders of Securities
notice of certain continuing Defaults if it determines that withholding notice
is in their interest.

16.      Trustee Dealings with Company.

                 The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company, its Subsidiaries or their respective Affiliates as if it
were not the Trustee.

17.      No Recourse Against Others.

                 No stockholder, director, officer, employee or incorporator,
as such, of the Company or any of its Affiliates shall have any liability for
any obligation of the Company or any of its Affiliates under the Securities or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder of a Security by accepting a
Security waives and releases all such liability.  The waiver and release are
part of the consideration for the issuance of the Securities.

18.      Authentication.

                 This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

19.      Abbreviations and Defined Terms.

                 Customary abbreviations may be used in the name of a Holder of
a Security or an assignee, such as:  TEN COM (= tenants in common), TEN ENT (=

Uniform Security Identification Procedures, the Company has caused CUSIP

Securities.  No representation is made as to the accuracy of such numbers as

identification numbers printed hereon.

all outstanding awards under the Plan, the Board shall preserve the value of the
outstanding awards by adjusting the maximum number and class of shares available
under the Plan to reflect the effect on such event or change in the Company's
capital structure, and by making appropriate adjustments to the number and class
of shares subject to an outstanding award or the Option price of each
outstanding Option, except that any fractional shares resulting from such
adjustments shall be eliminated by rounding any portion of a share equal to .500
or greater up, and any portion of a share equal to less than .500 down, in each
case to the nearest

practices governing this Plan as it shall from time to time deem advisable;

settle all claims and disputes arising under the Plan;

         (c) delegate responsibility and authority for the operation and

responsibilities under the Plan; and

         (d) otherwise supervise the administration of the Plan; provided,
however, that the Board shall have no discretion with respect to the selection
of Eligible Directors to receive Options hereunder, the number of shares of
Common Stock covered by such Option or the price or timing of any Options

the Plan will be taken only if approved by the affirmative vote of a majority of

         (ii) Initial Grants Made On Or After February 10, 1998. With respect to

following the first annual meeting of the Company's shareholders to occur after

         (iv) Subsequent Grants Made On Or After February 10, 1998. With respect

         (e) Method of Exercise. Options may be exercised, in whole or in part,
at any time and from time to time during the Option exercise period, by giving
written notice of exercise to the Company specifying the number of shares to be
purchased. Such notice shall be accompanied by payment in full of the purchase
price, either in cash or by certified or bank check, or such other instrument as
the Board may accept. Payment in full or in part may also be made in the form of
unrestricted Common Stock already owned by the Optionee (and based upon the Fair
Market Value of the Common Stock so tendered as of the date the Option is
exercised, as determined by the Board). No shares of Common Stock shall be
issued until full payment therefor has been made. Eligible Directors shall
generally have the rights to dividends or other rights of a stockholder with
respect to shares subject to the Option when the Eligible Director has given
notice as to exercise, has paid in full for such shares and, if requested, has
given any representations required by the Board.

         (f) Non-transferability. No Option shall be transferable by the
Optionee otherwise than by will, by the laws of descent and distribution,
pursuant to a qualified domestic relations order or as permitted under the
Rules, and all Options shall be exercisable, during the Optionee's lifetime,
only by the Optionee.

         (g) Termination by Reason of Death. If an Optionee ceases to be an
Eligible Director by reason of death, any Option held by such Optionee may
thereafter be exercised to the extent then exercisable, by the legal
representative of the estate or by the legatee of the Optionee under 




                                       5
<PAGE>   6

the will of the Optionee, for a period of one year from the date of such death
or until the expiration of the stated term of such Option, whichever period is
shorter.

         (h) Termination by Reason of Disability. If an Optionee ceases to be an
Eligible Director by reason of Disability, any Option held by such Optionee may
thereafter be exercised by the Optionee, to the extent it was exercisable at the
time of termination, for a period of one year from the date of such termination
or until the expiration of the stated term of such Option, whichever period is
shorter; provided, however, that if the Optionee dies within such one-year
period, any unexercised Option held by such Optionee shall thereafter be
exercisable to the extent it was exercisable at the time of death for a period
of one year from the date of such death or until the expiration of the stated
term of such Option, whichever period is shorter.

         (i) Other Termination. If an Optionee ceases to be an Eligible Director
for any reason other than death or Disability (except as a result of becoming an
employee of the Company), any Option held by such Optionee may thereafter be
exercised by the Optionee, to the extent it was exercisable at the time of such
termination, for a period of three months from the date of such termination or
the expiration of the stated term of such Option, whichever period is shorter;
provided, however, that if the Optionee dies within such three-month period, any
unexercised Option held by such Optionee shall thereafter be exercisable, to the
extent to which it was exercisable at the time of death, for a period of one
year from the date of such death or until the expiration of the stated term of
the Option, whichever period is shorter. If an Optionee ceases to be an Eligible
Director by reason of his becoming an employee of the Company and his employment
with the Company is subsequently terminated, any Option held by such Optionee
may thereafter be exercised by the Optionee, to the extent that it was
exercisable at the time of such termination, for a period of three months from
the date of such termination or the expiration of the stated term of the Option,
whichever period is shorter; provided, however, that if the Optionee dies within
such three-month period, any unexercised Option held by such Optionee shall
thereafter be exercisable, to the extent to which it was exercisable at the time
of death, for a period of one year from the date of such death or until the
expiration of the stated term of the Option, whichever period is shorter.

         7.  Amendment and Termination.

         The Board may amend, alter or discontinue the Plan at any time and from
time to time (either by resolution or unanimous consent), but no amendment,
alteration, or discontinuation shall be made which would impair the rights of an
Optionee under an Option theretofore granted, without the Optionee's consent, or
which, without the approval of the Company's stockholders, would require
stockholder approval under the Rules or under the requirements of any applicable
federal or state law or regulation; provided, however, that in no event may the
provisions of the Plan respecting eligibility to participate be amended more
frequently than once every six months, other than to comport with changes in the
Code, or the Employee Retirement Income Security Act of 1974, as amended, and
any rules or regulations thereunder; provided, further, that any amendment
which, under the requirements of applicable federal or state law or regulation
or the rules of any stock exchange or automated quotation system on which the
Common Stock may then be listed or quoted must be approved by the stockholders
of the Company, shall not be 




                                       6
<PAGE>   7


effective unless and until such stockholder approval has been obtained in
compliance with such law; and provided, further, that any amendment that must be
approved by the stockholders of the Company in order to maintain the continued
qualification of the Plan under Rule 16b-3(c)(2)(ii) under the Exchange Act, or
any successor provision, shall not be effective unless and until such
stockholder approval has been obtained in compliance with such Rule. The
Committee may amend the terms of any Option theretofore granted, prospectively
or retroactively, but no such amendment shall impair the rights of any Optionee
without the Optionee's consent. Notwithstanding any provision herein to the
contrary, the Board shall have broad authority to amend the Plan or any Option
to take into account changes in applicable tax laws, securities laws, accounting
rules and other applicable state and federal laws.

         8.  Unfunded Status of the Plan.

         The Plan is intended to constitute an unfunded plan for incentive
compensation. With respect to any payments not yet made to an Optionee by the
Company, nothing contained herein shall give any such Optionee any rights that
are greater than those of a general creditor of the Company. In its sole
discretion, the Board may authorize the creation of trusts or other arrangements
to meet the obligations created under the Plan to deliver Common Stock or
payments in lieu thereof or with respect to awards hereunder.

         9.  General Provisions.

         (a) Representations by Optionees. The Board may require each Optionee
to represent to and agree with the Company in writing that the Optionee is
acquiring the shares of Common Stock without a view to distribution thereof. The
certificates for such shares may include any legend that the Company deems
appropriate to reflect any restrictions on transfer.

         (b) No Restrictions on Adoption of Other Compensation Arrangements.
Nothing contained in this Plan shall prevent the Board from adopting other or
additional compensation arrangements (subject to stockholder approval, if such
approval is required) and such arrangements may be either generally applicable
or applicable only in specific cases.

         (c) No Right to Continuing Employment or Re-election. The adoption of
the Plan shall not confer upon any Optionee any right to continued employment
with the Company nor shall it interfere in any way with the right of the Company
to terminate its relationship with any of its employees, directors, or
independent contractors at any time.

         (d) Tax Withholding. No later than the date as of which an amount first
becomes includable in the gross income of the Optionee for applicable income tax
purposes with respect to any award under the Plan, the Optionee shall pay to the
Company or make arrangements satisfactory to the Board regarding the payment of
any federal, state or local taxes of any kind required by law to be withheld
with respect to such amount. Unless otherwise determined by the Board, the
minimum required withholding obligations may be settled with Common Stock,
including Common Stock that is part of the award that gives rise to the
withholding requirement. The obligation of the Company under the Plan shall be
conditional upon such payment or arrangements and the Company shall to the
extent permitted by law have the right to deduct any 




                                       7
<PAGE>   8

such taxes from any payment of any kind otherwise due to the Optionee.

         (e) Right of First Refusal. At the time of grant, the Board may provide
in connection with any grant made under this Plan that the shares of Common
Stock received as a result of such grant shall be subject to a right of first
refusal pursuant to which the Optionee shall be required to offer to the Company
any shares that the Optionee wishes to sell with the price being the then Fair
Market Value of the Common Stock, subject to such other terms and conditions as
the Board may specify at the time of grant.

         (f) Designation of a Beneficiary. The Board shall establish such
procedures as it deems appropriate for an Optionee to designate a beneficiary to
whom any amounts payable in the event of the Optionee's death are to be paid.

         (g) Applicable Law. The Plan shall be governed by and subject to the
laws of the State of Delaware and to all applicable laws and to the approvals by
any governmental or regulatory agency as may be required.

         (h) Severability. If any provision of this Plan shall be held illegal
or invalid for any reason, such illegality or invalidity shall not affect the
remaining provisions of this Plan, but this Plan shall be construed and enforced
as if such illegal or invalid provision had never been included herein.

         (i) Compliance with Rule 16b-3. It is the intent of the Company that
this Plan comply in all respects with applicable provisions of Rule 16b-3 under
the Exchange Act in connection with any grant of Options. Accordingly, if any
provision of this Plan or any agreement hereunder does not comply with the
requirements of Rule 16b-3 as then applicable to any such Optionee, or would
cause any Optionee to no longer be deemed a "disinterested person" within the
meaning of Rule 16b-3, such provision shall be construed or deemed amended to
the extent necessary to conform to such requirements with respect to such
Optionee. In addition, the Board shall have no authority to make any amendment,
alteration, suspension, discontinuation, or termination of the Plan or any
agreement hereunder to take other action if and to the extent such authority
would cause an Optionee's transactions under the Plan not to be exempt, or
Optionees no longer to be deemed "disinterested persons," under Rule 16b-3 of
the Exchange Act.

         10. Effective Date and Term of the Plan.

         The Plan shall be effective as of November 14, 1994. No Options shall
be granted pursuant to the Plan on or after November 14, 2004, but Options
granted prior to such date may extend beyond that date.

                      whether now or hereafter existing, as defined in Section

         3. STOCK SUBJECT TO THE PLAN. Without limiting the application of
Section 11 of the Plan, the maximum aggregate number of Shares which may be
optioned and sold under the Plan is 18.5% of the total number of Shares
outstanding at the beginning of each calendar year. The Shares may include
authorized but unissued or reacquired Common Stock. If an Option is surrendered
for cash or other consideration or expires or becomes unexercisable for any
reason without having been exercised in full, the Shares which were subject to
the Option but as to which the Option was not exercised shall become available
for future Option grants under the Plan, unless the Plan shall have been
terminated. Shares subject to an Option that is forfeited or settled in cash or
otherwise terminated without a delivery of Shares to the Optionee, including
Shares withheld in payment of taxes relating to awards and the number of Shares
equal to the number of Shares surrendered in payment of the exercise price of
Options (or any other awards in the nature of purchase rights) or taxes relating
to awards, will again be available for awards under the Plan.

                  The Committee may adopt reasonable counting procedures to
ensure appropriate counting, avoid double counting and make adjustments if the
number of Shares actually delivered differs from the number of Shares previously
counted in connection with an award.


                  The Company intends that as long as it is not subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act and is not an
investment company registered or required to be registered under the Investment
Company Act of 1940, all offers and sales of Options and Common Stock issuable
upon exercise of any Option shall be exempt from registration under the
provisions of Section 5 of the Securities Act, and the Plan and the Trust shall
be administered in such a manner so as to preserve such exemption. The Company
intends that the Plan shall constitute a written compensatory benefit plan
within the meaning of Rule 701(b) of 17 CFR Section 230.701 promulgated by the
Securities and Exchange Commission pursuant to such Act. The Committee shall
designate which Options granted under the Plan by the Company are intended to be
granted in reliance on Rule 701.


         4. ADMINISTRATION OF THE PLAN.


            (a)       Procedure. The Plan shall be administered by the Board. 
                      The Board may appoint a Compensation Committee consisting
                      of not less than two (2) members of the Board to 
                      administer the Plan, subject to the direction of the 
                      Board and such terms and conditions as the Board may 
                      prescribe. 


                                       3

                      Once appointed, the Committee shall continue to serve
                      until otherwise directed by the Board.


                      From time to time, the Board may increase the size of the
                      Committee and appoint additional members thereof, remove
                      members (with or without cause) and appoint new members in
                      substitution therefor, fill vacancies, however caused, and
                      remove all members of the Committee and, thereafter,
                      directly administer the Plan. Members of the Board or
                      Committee who are either eligible for Options or have been
                      granted Options (either directly or as a beneficiary of
                      the Trust) may vote on any matters affecting the
                      administration of the Plan or the grant of Options
                      pursuant to the Plan, except that no such member shall act
                      upon the granting of an Option to such member (either
                      directly or as a beneficiary of the Trust) but any such
                      member may be counted in determining the existence of a
                      quorum at any meeting of the Board or the Committee during
                      which action is taken with respect to the granting of an
                      Option to such member (either directly or as a beneficiary
                      of the Trust).


                      The Committee shall meet at such times and places and upon
                      such notice as the Chairperson determines. A majority of
                      the Committee shall constitute a quorum. Any acts by the
                      Committee may be taken at any meeting at which a quorum is
                      present and shall be by majority vote of those members
                      entitled to vote. Additionally, any acts reduced to
                      writing or approved in writing by all of the members of
                      the Committee shall be valid acts of the Committee.


            (b)       Procedure After Registration Date.  Notwithstanding 
                      subsection (a) above, after the Registration Date, the
                      Plan shall be administered either by: (i) the full Board;
                      or (ii) a Committee of two (2) or more directors, each of
                      whom is a Non-Employee Director. After the Registration
                      Date, the Board shall take all action necessary to
                      administer the Plan in accordance with the then effective
                      provisions of Rule 16b-3 promulgated under the Exchange
                      Act, provided that any amendment to the Plan required for
                      compliance with such provisions shall be made in
                      accordance with Section 13 of the Plan.


            (c)       Powers of the Committee.  Subject to the provisions of the
                      Plan, the Committee shall have discretionary authority:
                      (i) to determine, upon review of relevant information, the
                      fair market value of the Common Stock; (ii) to determine
                      the exercise price of Options to be granted, the persons
                      (including the Trust) to whom and the time or times at
                      which Options shall be granted, and the number of Shares
                      to be represented by each Option; (iii) to interpret the
                      Plan; (iv) to prescribe, amend and rescind rules and
                      regulations relating to the Plan; (v) to establish the



                                       4
<PAGE>   5


                      terms and conditions of each Option granted under the Plan
                      (which terms and conditions need not be identical in any
                      two Options) and, with the consent of the holder thereof,
                      to modify or amend any Option; (vi) to authorize any
                      person to execute on behalf of the Company any instruments
                      required to effect the grant of an Option awarded by the
                      Committee; (vii) to accelerate or (with the consent of an
                      Optionee) to defer an exercise date of any Option subject
                      to the provisions of Section 9(a) of the Plan; (viii) to
                      determine whether Options granted under the Plan will be
                      Incentive Stock Options or Nonstatutory Stock Options; and
                      (ix) to make all other determinations deemed necessary or
                      advisable for the administration of the Plan.


            (d)       Effect of Committee's Decision. All decisions, 
                      determinations and interpretations of the Committee shall
                      be final and binding on all potential or actual Optionees,
                      any other holder of an Option or other equity security of
                      the Company and all other persons. In any controversy
                      regarding the administration of the Plan, any arbitrator
                      or court reviewing any decision, determination or
                      interpretation by the Committee shall not set aside or
                      modify such decision, determination or interpretation
                      unless it is arbitrary, capricious or clearly contrary to
                      the terms of the Plan.


         5. ELIGIBILITY.


            (a)       Persons Eligible to Participate. Options under the Plan 
                      may be granted only to Employees or the Trust for the
                      benefit of Employees whom the Committee may designate from
                      time to time. Each Employee in certain jurisdictions, as
                      designated by the Committee from time to time, must be a
                      beneficiary of the Trust in order to be a participant
                      under this Plan. Incentive Stock Options may be granted
                      only to Employees. An Optionee who has been granted an
                      Option may receive an additional Option or Options, if he
                      or she is otherwise eligible for such grant. Such
                      additional Option or Options may be granted to the Trust
                      for the benefit of such eligible Optionee. However, the
                      aggregate fair market value (determined in accordance with
                      the provisions of Section 8(a) of the Plan) of the Shares
                      subject to one or more Incentive Stock Options that are
                      exercisable for the first time by an Optionee during any
                      calendar year (under all stock option plans of the
                      Company) shall not exceed $100,000 (determined as of the
                      grant date).


            (b)       No Right to Continuing Employment. Neither the 
                      establishment nor operation of the Plan or the Trust shall
                      confer upon any Optionee or any other person any right
                      with respect to continuation of employment or other
                      service with the Company, nor shall the Plan or the Trust
                      interfere 


                                       5
<PAGE>   6

                      in any way with the right of the Optionee or other person
                      or the right of the Company to terminate such employment
                      or service at any time.


         6. TERM OF PLAN. This Third Amended and Restated Plan shall become
effective upon its adoption by the Board. The Plan shall continue until November
14, 2004 unless sooner terminated under Section 13 of the Plan.


         7. TERM OF OPTION. Unless the Committee determines otherwise, at the
time of the grant of an Option, the term of each Nonstatutory Stock Option
granted under the Plan shall be ten (10) years and one (1) day from the date of
grant; and the term of each Incentive Stock Option shall be ten (10) years from
the date of grant. No Option shall be exercisable after the expiration of its
term. In all cases the terms of an Option shall be set forth in the Option
Agreement.


         8.       OPTION PRICE, CONSIDERATION AND RESTRICTIONS.


                  (a)     Option Price.  Except as provided in subsection 8(b),
                          the option price for the Shares to be issued pursuant
                          to any Option shall be such price as is determined by
                          the Committee which, in the case of Incentive Stock
                          Options, shall in no event be less than the fair
                          market value of such Shares on the date the Option is
                          granted. Fair market value of the Common Stock shall
                          be determined by the Committee using such criteria as
                          it deems relevant; provided, however, that where there
                          is a public market for the Common Stock, the fair
                          market value per Share shall be the average of the
                          last reported bid and asked prices of the Common Stock
                          on the date of grant, as reported in The Wall Street
                          Journal (or, if not so reported, as otherwise reported
                          by the National Association of Securities Dealers
                          Automated Quotation ("NASDAQ") System; or, in the
                          event the Common Stock is listed on a national
                          securities exchange, within the meaning of Section 6
                          of the Exchange Act, the fair market value per Share
                          shall be the closing price on such exchange on the
                          date of grant of the Option, as reported in The Wall
                          Street Journal.


                  (b)     Ten Percent Shareholders. No Incentive Stock Option
                          shall be granted to any Employee who, at the date such
                          Option is granted, owns (within the meaning of Section
                          424(d) of the Code) more than ten percent (10%) of the
                          total combined voting power of all classes of stock of
                          the Company, its Parent or any Subsidiary, unless the
                          option price for the Shares to be issued pursuant to
                          such Incentive Stock Option is equal to at least 110
                          percent (110%) of the fair market value of such Shares
                          on the grant date as determined by the Committee in
                          the manner set forth in subsection (a) above.


                  (c)     Consideration.  The consideration to be paid for the 
                          Shares to be issued upon exercise of an Option shall
                          be payment in cash or by check or with 


                                       6
<PAGE>   7

                          Shares of the Company's Common Stock. The Committee
                          may also, in its discretion, authorize at the time of
                          the grant of the Option payment in some other
                          consideration or method (such as by promissory note)
                          for the issuance of Shares as may be permitted under
                          Section 157 of the General Corporation Law of the
                          State of Delaware. Any cash or other property received
                          by the Company from the sale of Common Stock pursuant
                          to the Plan shall constitute part of the general
                          assets of the Company.


         9.       EXERCISE OF OPTION.


                  (a)     Vesting Period.  Any Option granted hereunder shall be
                          exercisable at such times and under such conditions as
                          determined by the Committee and as shall be
                          permissible under the terms of the Plan, which times
                          and conditions shall be specified in the Option
                          Agreement evidencing the grant of the Option. Unless
                          the Committee specifically determines otherwise in the
                          Option Agreement, each Option shall vest and become
                          exercisable, cumulatively, by an Optionee or by the
                          Trust on behalf of an Optionee, to the extent of (i)
                          one-third (1/3) of the Optioned Shares as of the first
                          anniversary of the date on which the Option is
                          granted, (ii) two-thirds (2/3) of the Optioned Shares
                          as of the second anniversary of the date on which the
                          Option is granted, and (iii) all of the Optioned
                          Shares as of the third anniversary of the date on
                          which the Option is granted, subject to the Optionee's
                          Continuous Employment; provided, however, that the
                          Optionee must complete twelve (12) months of
                          employment to exercise an Incentive Stock Option. An
                          Option may not be exercised for fractional Shares or
                          for less than ten (10) Shares.


                  (b)     Exercise Procedures.  An Option shall be deemed to be
                          exercised when written notice of such exercise has
                          been given to the Company in accordance with the terms
                          of the Option Agreement by an Optionee or by the Trust
                          on behalf of an Optionee and full payment for the
                          Shares with respect to which the Option is exercised
                          has been received by the Company. As soon as
                          administratively practicable following the exercise of
                          an Option in the manner set forth above, the Company
                          shall issue or cause its transfer agent to issue stock
                          certificates representing the Shares purchased. Until
                          the issuance of such stock certificates (as evidenced
                          by the appropriate entry on the books of the Company
                          or of a duly authorized transfer agent of the
                          Company), no right to vote or receive dividends or any
                          other rights as a stockholder shall exist with respect
                          to the Optioned Shares notwithstanding the exercise of
                          the Option. Except as provided in Section 11 below, no
                          adjustment will be made for a dividend or other rights
                          for which the record date occurs prior to the date the
                          stock certificates are issued.

                  (c)      Exercise of Option with Stock or Net of Exercise 
                           Price. The Committee, in its discretion, may permit
                           an Optionee or the Trust on behalf of an Optionee to
                           exercise an Option in whole or in part by (i)
                           delivering whole Shares of the Company's Common Stock
                           previously owned by such Optionee or the Trust on
                           behalf of an Optionee (whether or not acquired
                           through the prior exercise of a stock option) having
                           a fair market value equal to the option price; or
                           (ii) directing the Company to withhold from the
                           Shares that would otherwise be issued upon exercise
                           of the Option that number of whole Shares having a
                           fair market value equal to the Option price. Shares
                           of the Company's Common Stock so delivered or
                           withheld shall be valued at their fair market value
                           at the close of the last business day immediately
                           preceding the date of exercise of the Option, as
                           determined by the Committee. Any balance of the
                           Option price shall be paid in cash. Any Shares
                           delivered or withheld in accordance with this
                           provision shall again become available for purposes
                           of the Plan and for Options subsequently granted
                           thereunder.


                   (d)     Termination of Status as Employee. If an Optionee 
                           shall cease to be an Employee for any reason other
                           than permanent and total disability (within the
                           meaning of Section 22(e)(3) of the Code as determined
                           in the sole discretion of the Committee), retirement
                           or death, such individual's Option (irrespective of
                           whether such Option has been transferred to the
                           Trust) shall automatically terminate thirty (30) days
                           following the date he or she ceases to be an
                           Employee, unless the Committee, in its discretion,
                           determines to permit a longer post-employment
                           exercise period (which shall in no event extend
                           beyond the term of the relevant Option). Prior to
                           such termination of the Option, the Optionee or the
                           Trust on behalf of an Optionee may exercise such
                           Option to the extent that the Optionee or the Trust
                           on behalf of an Optionee was entitled to exercise on
                           the exercise date, subject to the condition that no
                           Option shall be exercised after the expiration of the
                           term of the Option.


                  (e)      Disability of Optionee.  In the event of the 
                           permanent and total disability (within the meaning of
                           Section 22(e)(3) of the Code as determined in the
                           sole discretion of the Committee) during the term of
                           the Option of an Optionee who is at the time of such
                           disability, or was within the 90-day period prior
                           thereto, an Employee and who was in Continuous
                           Employment as such from the date of the grant of the
                           Option until the date of disability or termination,
                           the Option may be exercised at any time within one
                           (1) year following the date of disability (or such
                           longer period as may be established by the Committee,
                           in its discretion), but only to the extent that the
                           Optionee or the Trust was entitled to exercise the
                           Option at the time of the termination or disability,
                           whichever comes 


                                       8
<PAGE>   9

                           first, subject to the condition that no Option shall
                           be exercised after the expiration of the term of the
                           Option.


                  (f)      Retirement of Optionee.  In the event of the 
                           retirement during the Option period of an Optionee
                           who is at the time of such retirement, or was within
                           the 90-day period prior thereto, an Employee and who
                           was in Continuous Employment as such from the date of
                           the grant of the Option until the date of the
                           retirement, the Option may be exercised by the
                           Optionee or the Trust on behalf of an Optionee at any
                           time within ninety (90) days following the retirement
                           date (or such longer period as may be established by
                           the Committee, in its discretion), but only to the
                           extent that the Optionee or the Trust was entitled to
                           exercise the Option at the time of the Optionee's
                           retirement, subject to the condition that no Option
                           shall be exercised after the expiration of the Option
                           period. For purposes of this Section 9, the term
                           "retirement" shall mean voluntary termination of
                           employment by an Employee who is at least age
                           fifty-five (55) and who has completed five (5) years
                           of employment with the Company.


                  (g)      Death of Optionee.  In the event of the death during
                           the term of the Option of an Optionee who is at the
                           time of his or her death, or was within the 90-day
                           period immediately prior thereto, an Employee and who
                           was in Continuous Employment as such from the date of
                           the grant of the Option until the date of death, the
                           Option may be exercised for a period up to one (1)
                           year following the date of death (or such longer
                           period as may be established by the Committee, in its
                           discretion), at any time prior to the expiration of
                           the term of the Option, by the Optionee's estate or
                           by a person who acquired the right to exercise the
                           Option by bequest, inheritance or otherwise as a
                           result of the Optionee's death, or by the Trust for
                           the benefit of such estate or person, but only to the
                           extent that the Optionee or Trust was entitled to
                           exercise the Option at the time of the death, subject
                           to the condition that no Option shall be exercised
                           after the expiration of the Option period.


                  (h)      Tax Withholding.  When an Optionee or the Trust on 
                           behalf of an Optionee is required to pay to the
                           Company an amount with respect to income or
                           employment tax withholding obligations in connection
                           with the exercise of an Option granted under the
                           Plan, the Optionee or the Trust on behalf of an
                           Optionee may elect, prior to the date the amount of
                           such withholding is determined (the "Tax Date") to
                           make such payment, or such increased payment as the
                           Optionee or the Trust on behalf of an Optionee elects
                           to make up to the maximum federal, state and local
                           marginal tax rates (including any related obligation
                           under the Federal Insurance Contribution Act)
                           applicable to the Optionee and the particular



                                       9
<PAGE>   10

                           transaction, by (i) delivering cash; (ii) delivering
                           part or all of the payment in previously owned stock
                           (whether or not acquired through the prior exercise
                           of a stock option); or (iii) subject to the consent
                           of the Committee, irrevocably directing the Company
                           to withhold from the Shares that would otherwise be
                           issued upon exercise of the Option that number of
                           whole Shares having a fair market value equal to the
                           amount of tax required or elected to be withheld (a
                           "Withholding Election"). If an Optionee's Tax Date is
                           deferred beyond the date of exercise and the Optionee
                           or the Trust on behalf of an Optionee makes a
                           Withholding Election, the Optionee or the Trust on
                           behalf of an Optionee will receive the full amount of
                           Shares otherwise issuable upon exercise of the Option
                           minus the number of Shares necessary to satisfy the
                           minimum withholding requirements measured on the date
                           the Option is exercised (or such higher payment as
                           the Optionee or the Trust may have elected to make)
                           with adjustments to be made in cash after the Tax
                           Date.


                           Any adverse consequences incurred by an Optionee with
                           respect to his or her participation in the Plan or
                           the Trust, the use of Shares to pay any part of the
                           Option price or income or employment tax arising in
                           connection with the exercise of an Option (including
                           without limitation any adverse tax consequences
                           arising as result of a disqualifying disposition
                           within the meaning of Section 422 of the Code) shall
                           be the sole responsibility of the Optionee or Trust.
                           The Company does not warrant or represent to the
                           Optionee any tax consequence of any transaction under
                           this Plan or the Trust, including the initial and
                           continuing satisfaction of the conditions for an
                           Incentive Stock Option under Section 422 of the Code.


         10.      NON-TRANSFERABILITY OF OPTIONS AND SHARES OF COMMON STOCK.


                  (a)      Options.  An Option may not be sold, pledged, 
                           assigned, hypothecated, transferred or disposed of in
                           any manner other than by will or by the laws of
                           descent and distribution and may be exercised, during
                           the lifetime of the Optionee, only by the Optionee.
                           Notwithstanding the preceding sentence, (i) an
                           Optionee who is eligible to participate in the Trust
                           may transfer or direct the Company to transfer
                           Options or Optioned Shares to the Trust, subject to
                           the terms and conditions of this Plan and the Trust,
                           and (ii) the Option may be transferred to a spouse of
                           the Optionee only upon approval of the Committee,
                           providing all the conditions of exercisability and
                           vesting have been met. If the Option Agreement
                           permits, the Optionee may designate a beneficiary who
                           may (i) exercise an Option under Section 9(g) above,
                           or (ii) receive Shares issued pursuant to the
                           exercise of an Option where the death of an 


                                       10
<PAGE>   11

                           Optionee occurs between the date on which the
                           Optionee exercises the Option and the date the
                           Company issues the Shares.


                  (b)      Shares of Common Stock.  The Committee may impose 
                           such other restrictions on Shares issued under this
                           Plan as it deems advisable. Except as otherwise
                           provided by the Committee, and except for transfers
                           of Optioned Shares to the Trust, Optioned Shares
                           acquired under an Option may not be sold, pledged,
                           assigned, hypothecated, transferred or disposed of in
                           any manner other than by will or by the laws of
                           descent and distribution (provided the assigns or
                           successors in interests to such Optioned Shares
                           remain subject to the terms and conditions of this
                           Plan and the Trust including the Company's right of
                           first refusal to repurchase the Optioned Shares)
                           without the Optionee first offering to the Company
                           the right to purchase the Optioned Shares at the fair
                           market value of the Shares on the date such offer is
                           received by the Secretary of the Company. If the
                           Company fails to accept the offer to purchase such
                           Shares within seven (7) days after receipt of such
                           offer, the Optionee shall be free to sell or transfer
                           such Shares at the same fair market value at which
                           they were offered to the Company. If the Optionee
                           does not sell or transfer such Shares within ninety
                           (90) days, then the restrictions of this Section 10
                           shall remain in effect. The certificates representing
                           the Optioned Shares shall bear a legend which shall
                           give notice of such restrictions on the
                           transferability of the Optioned Shares.


         11.     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. Subject to any 
required action by the shareholders of the Company, the number of Shares of
Common Stock covered by each outstanding Option and the per share price thereof
in each such Option, shall be proportionately adjusted for any increase or
decrease in the number of issued Shares of Common Stock resulting from a stock
split, reverse stock split, combination, reclassification, the payment of a
stock dividend on the Common Stock or any other increase or decrease in the
number of such Shares of Common Stock effected without receipt of consideration
by the Company; provided, however, that conversion of any convertible securities
of the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Committee, whose
determination in that respect shall be final, binding and conclusive. Except as
expressly provided herein, no issue by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall affect
(and no adjustment by reason thereof shall be made with respect to) the number
or price of Shares subject to an Option.


         The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the number or class of securities
covered by any Option, as well as the price to be paid therefor, in the event of
the Company's effecting one or more reorganizations, recapitalizations, rights
offerings, or other increases or reductions of the number of Shares of 

                                       11

<PAGE>   12

its outstanding Common Stock, or in the event of the Company's being
consolidated with or merged into any other corporation.


         Unless otherwise determined by the Board, upon the dissolution or
liquidation of the Company or upon any merger or consolidation, if the Company
is not the surviving corporation, the Options (irrespective of whether such
Options have been transferred to the Trust) granted hereby shall terminate and
thereupon become null and void; provided, however, that the Optionee and the
Trust shall be given not less than ten (10) days' notice of such event and the
exercisability of each outstanding Option shall be accelerated so that the
Optionee and the Trust may within such period exercise up to the entire
unexercised portion of their respective options. Upon the occurrence of any such
event, any Option not exercised pursuant thereto shall terminate.


         12. TIME OF GRANTING OPTIONS. Unless otherwise specified by the
Committee or as may be required by applicable law, regulation or rule (including
rules of stock exchanges or other self-regulatory organizations), the date of
grant of an Option under the Plan shall be the date on which the Committee makes
the determination to grant such Option or, if later, the date on which are
satisfied any conditions precedent to such grant. As soon as feasible after the
Committee makes its determination regarding the grant of an Option, the
Committee shall notify the individual or class of persons who are the recipients
of the grant.


         13. AMENDMENT AND TERMINATION OF THE PLAN. The Board may amend or
terminate the Plan from time to time in such respects as the Board may deem
advisable, except that amendments or modifications to the Plan shall be subject
to shareholder approval (a) if such amendment or modification increases the
Shares available for issuance under the Plan or (b) to the extent required by
applicable law, regulation or rule (including rules of stock exchanges or other
self-regulatory organizations). Any amendment or termination of the Plan shall
not adversely affect any Option already granted without the relevant Optionee's
consent; and if no such consent is secured such Option shall remain in full
force and effect as if the Plan had not been amended or terminated.


         14. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with

and the issuance and delivery of such Shares pursuant thereto shall comply with
all relevant provisions of law, including, without limitation, the Securities
Act, the Exchange Act, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the Shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect

         15. RESERVATION OF SHARES. During the term of this Plan, the Company
will at all times reserve and keep available the number of Shares as shall be
sufficient to satisfy the requirements of the Plan. Inability of the Company to
obtain from any regulatory body having jurisdiction and authority deemed by the
Company's counsel to be necessary to the lawful issuance and sale of any Shares
hereunder shall relieve the Company of any liability in respect to the
nonissuance or sale of such Shares as to which such requisite authority shall
not have been obtained.


         16. INFORMATION TO OPTIONEE. During the term of any Option granted
under the Plan, the Company shall provide or otherwise make available to each
Optionee and the Trust a copy of its annual report to shareholders and financial
information which is provided to its shareholders in accordance with the
provisions of the Company's Bylaws and applicable law.


         17. OPTION AGREEMENT. All Options granted under Plan shall be evidenced
by Option Agreements.


         18. BEST PAYMENTS. If the gross amount of any payment or benefit under
the Plan, either separately or in combination with any other payment or benefit
payable by the Company or pursuant to a plan of the Company would constitute a
parachute payment within the meaning of Code Section 280G, then the total
payments and benefits accrued and payable under this Plan shall not exceed the
amount necessary to maximize the amount received by the Optionee after payment
of all employment, income and excise taxes imposed on the Optionee with respect
to such payments and benefits. The Optionee may elect, by written notice to the
Board, which items of compensation, if any, shall be reduced so as to meet the
requirements of the preceding sentence. If there is a dispute between the
Company and the Optionee regarding (i) the extent, if any, to which any payments
or benefits to the Optionee are parachute payments or excess parachute payments,
under Code Section 280G, (ii) the base amount of such Optionee's compensation,
under Code Section 280G, or (iii) the status of such Optionee as a disqualified
individual, under Code Section 280G, such dispute shall be resolved as provided
in Section 20 below. Within 30 days of the Optionee's receiving notice of (a) a
change of control of the Company within the meaning of Code Section 280G or (b)
the Optionee's termination of service with the Company or the Company's
receiving notice of such termination, either the Optionee or the Company may
request, in accordance with Section 19 below, (a) a determination of the amount
of any parachute payment, excess parachute payment, or base amount of
compensation, or (b) a determination of the reduction necessary to maximize the
amount receivable by the Optionee as described above. Any fees, costs or
expenses incurred by the Optionee or the Trust in connection with such
determinations shall be paid by the Optionee.


         19. MANDATORY ARBITRATION. Any dispute arising out of or relating to
this Plan or any Option Agreement shall be resolved solely by arbitration before
one arbitrator in accordance with the Employee Benefit Plan Claim Rules of the
American Arbitration Association. The location of the arbitration proceeding
shall be in Washington, D.C. Judgment on the award rendered by the arbitrator
may be entered in any court having 



                                       13
<PAGE>   14

jurisdiction. Each party to any dispute regarding the Plan or an Option
Agreement shall pay the costs and fees (including attorneys' fees) of presenting
his, her or its case in arbitration. All other costs of arbitration, including
the costs of any transcript of the proceedings, administrative fees and the
arbitrator's fees, shall be borne equally by the parties. All statutes of
limitation which would otherwise be applicable shall apply to any arbitration
proceeding. The provisions of this Section 20 are exclusive for all purposes and
applicable to any and all disputes arising out of or relating to the Plan or any
Option Agreement. The arbitrator who hears and decides any dispute shall have
jurisdiction and authority to award only compensatory damages to make whole a
person or entity sustaining foreseeable economic loss, and shall not have
jurisdiction or authority to make any other award of any type, including,
without limitation, punitive damages, unforeseeable economic damages, adverse
tax consequences, damages for pain, suffering or emotional distress, or any
other kind or form of damages. The remedy, if any, awarded by the arbitrator
shall be the sole and exclusive remedy for any dispute which is subject to
arbitration under this Plan.


         20. GOVERNING LAW. The validity, construction and effect of the Plan
and any agreement hereunder shall be determined in accordance with the laws of
the State of Delaware and applicable federal law.


         21. COMPLIANCE WITH RULE 16B-3. It is the intent of the Company that
this Plan and the Trust comply in all respects with applicable provisions of
Rule 16b-3 under the Exchange Act in connection with any grant of Options.
Accordingly, if any provision of this Plan or the Trust or any agreement
hereunder does not comply with the requirements of Rule 16b-3 as then applicable
to any such Optionee, such provision shall be construed or deemed amended to the
extent necessary to conform to such requirements with respect to such Optionee.
In addition, the Board shall have no authority to make any amendment,
alteration, suspension, discontinuation, or termination of the Plan or the Trust
or any agreement hereunder to take other action if and to the extent such
authority would cause an Optionee's transactions under the Plan or the Trust not
to be exempt under Rule 16b-3 of the Exchange Act.

3.       STOCK SUBJECT TO THE PLAN.

                  cancellation of any Option granted under the Plan without the

                  Receipts) subject to or reserved for such Option may be used

                  event may the number of Option Shares for which Receipts will
                  be issued hereunder exceed 24,760. Any Receipts and Option
                  Shares withheld or surrendered to arrange for the payment of
                  withholding taxes pursuant to Section 7(n) or withheld or
                  surrendered in full or partial payment of the exercise price
                  of an Option pursuant to Section 7(e) may be used again in
                  connection with the grant of new Options, subject to the
                  maximum limitation of 24,760 Receipts and Option Shares.

         (c)      Future Value Determinations. So long as the Company is
                  privately-owned, an internationally recognized investment
                  banking firm annually shall determine the Fair Market Value of
                  the Option Shares as at December 31, and deliver to the
                  Company and the Participants a certificate setting forth the
                  fair market value of the Option Shares as soon as practicable
                  after the completion of the audit of the financial statements
                  of the Company, but no later than March 15 of the immediately
                  following year, such Fair Market Value shall be applicable for
                  purposes of the Plan for the immediately following
                  twelve-month period..

4.       ADMINISTRATION OF THE PLAN.

                  terms and conditions as the Board may prescribe. Members of
                  the Committee may not hold or receive an Option. Once
                  appointed, the Committee shall continue to serve until

                  may increase the size of the Committee, remove members (with
                  or without cause), and appoint replacement or additional
                  members of the Committee. The Board also may remove all
                  members of the Committee and, thereafter, directly administer
                  the Plan.

         (b)      Powers of the Committee.  Subject to the provisions of the 
                  Plan, the Committee shall have discretionary authority to: (i)
                  grant Options to Employees; (ii) determine the number of
                  Shares represented by Receipts to be issued upon exercise of

                  rules and regulations relating to the Plan; (v) establish the
                  terms and conditions of each Option granted under the Plan
                  (which terms and conditions need not be identical in any two
                  Options); (vi) with the consent of the holder thereof, modify
                  or amend any Option; (vii) authorize any person to execute on
                  behalf of the Company any instruments required to effect the
                  grant of an Option awarded by the Committee; (viii) accelerate
                  or (with the consent of an Optionee) defer an exercise date of
                  any Option subject to the provisions of Section 7(a) of the
                  Plan; (ix) make changes to the Plan which are required to
                  comply with any applicable securities law; and (x) to make all
                  other determinations deemed necessary or advisable for the
                  administration of the Plan. The Committee shall also
                  constitute the governing board of the Trust.

         (c)      Indemnification.  No member of the Committee shall be liable  
                  for any action or determination made in good faith with
                  respect to the Plan or any Option awarded under it. To the
                  maximum extent permitted by applicable law, each member of the
                  Committee shall be indemnified and held harmless by the
                  Company against any cost or expense (including legal fees) or
                  liability (including any sum paid in settlement of a claim
                  with the approval of the Company) arising out of any act or
                  omission to act in connection with the Plan unless arising out
                  of such member's own fraud or bad faith. Such indemnification
                  shall be in addition to any rights of indemnification the
                  members may have as members of the Board or under the by-laws
                  of the Company.

         (d)      Effect of the Committee's Decision. All decisions,
                  determinations and interpretations of the Committee shall be
                  final and binding on all potential or actual Optionees, any
                  other holder of an Option, Receipt or other equity security of
                  the Company, and all other persons. The Committee may employ
                  counsel to advise it on any matter. In any controversy
                  regarding the administration of the Plan, any arbitrator or
                  court reviewing any decision, determination or interpretation
                  of the Committee shall not set aside or modify such decision,
                  determination or interpretation unless it is arbitrary,
                  capricious or clearly contrary to the terms of the Plan.

5.       ELIGIBILITY.

         (a)      Persons Eligible to Participate. Options under the Plan shall
                  be granted only to Employees. Each Employee who is nominated
                  for a grant of Initial Options shall, as a condition to such
                  grant, surrender and agree to the termination of any Original
                  Options granted pursuant to the Original Plan.

         (b)      No Right to Continuing Employment. Neither the establishment
                  nor operation of the Plan shall confer upon any Optionee or
                  any other person any right with respect to continuation of
                  employment or other service with the Company, any parent,
                  subsidiary or division, nor shall the Plan interfere in any
                  way with the right of the Optionee or other person or the
                  right of the Company, parent, subsidiary or division to
                  terminate such employment or service at any time.

6.       TERM OF PLAN. The Plan shall become effective upon its adoption by the
Board and shall continue in effect until 6 December, 2004, unless terminated
earlier by the Board pursuant to Section 10 of the Plan.

7.       TERM AND CONDITIONS OF OPTIONS. Each Option shall be evidenced by an 
Option Agreement, in form and substance as shall be determined by the Committee,
and shall be subject to the following terms and conditions and to such other
terms and conditions determined by the Committee:

         (a)      Term. The term of each Option, except Initial Options, granted
                  under the Plan shall be ten (10) years from the date of grant
                  of such Option unless terminated earlier under the terms
                  hereof or the applicable Option Agreement. The term of any
                  Initial Option shall be ten (10) years from the date of grant
                  of the Original Option it replaces. Upon the expiration of the
                  term of each Option and without any action by the Company or
                  Committee, no Option shall be exercisable after the expiration
                  of its term.

         (b)      Exercise Price. The price at which a Receipt for an Option
                  Share may be purchased pursuant to the exercise of an Option
                  shall be determined by the Committee at the time of grant of
                  such Option provided that except with respect to the Initial
                  Options, such exercise price shall not be less than the Fair
                  Market Value of that underlying Option Share on the date of
                  the grant of the Option

         (c)      Vesting Period. Any Option granted hereunder shall be
                  exercisable at such times and under such conditions as
                  determined by the Committee and as shall be permissible under
                  the terms of the Plan, but only after the Optionee shall have
                  satisfied all applicable conditions to such exercise. Unless
                  the Committee specifically determines otherwise in the Option
                  Agreement at the time of the grant of the Option, each Initial
                  Option shall vest and become exercisable in accordance with
                  the vesting provision of the Original Options granted to each
                  Employee under the Original Plan.

         (d)      Exercise Procedures. An Option shall be deemed to be exercised
                  when written notice of such exercise has been given to the
                  Company and to the member (designated by the Company) of the
                  Committee (which also serves as governing Board of the Trust)
                  in accordance with the terms of the applicable Option
                  Agreement by the person entitled to exercise the Option, and
                  full payment for the Receipts for Option Shares with respect
                  to which the Option is exercised has been received by the
                  Company. As soon as administratively practicable following the
                  exercise of an Option in the manner set forth herein, the
                  Committee shall cause the Trust to issue Receipts for the
                  Option Shares represented thereby. An Optionee shall be deemed
                  to be the beneficial holder of the number of the Option Shares
                  underlying the Receipts acquired pursuant to the exercise of
                  an Option as of the date of exercise of the Option. When
                  Options have been duly exercised hereunder and under the
                  Option Agreements, the Company shall issue to the Trust for
                  the benefit of the Optionee a number of Option Shares to the
                  Trust equal to the number of Receipts issued to such Optionee.

         (e)      Consideration. The consideration to be paid for the Receipts
                  upon exercise of an Option shall be made either (i) in cash or
                  cash equivalent, including cashiers' check; (ii) by surrender
                  to the Purchase Office of previously-acquired Receipts of
                  which underlying Option Shares have a Fair Market Value at the
                  time of such surrender at least equal to the Exercise Price of
                  the Options; (iii) through the withholding by the Company of
                  Receipts of which underlying Option Shares have a Fair Market
                  Value at the time of withholding at least equal to the
                  Exercise Price of the Options; or (iv) by a combination of the
                  foregoing.

         (f)      Adjustments Upon Changes in Capitalization.

                   (i)    Subject to any required action by the shareholders of 
                          the Company, the number of Receipts for Option Shares
                          covered by each outstanding Option and the per-Receipt
                          exercise price for each such Option, shall be
                          proportionately adjusted for any increase or decrease
                          in the number of issued Shares resulting from a stock
                          split, reverse stock split, combination,
                          reclassification, the payment of a stock dividend on
                          the Stock of the Company, or any other increase or
                          decrease in the number of Shares of the Company
                          effected without receipt of consideration by the
                          Company; provided, however, that conversion of any
                          convertible securities of the Company shall not cause
                          such adjustment. Such adjustments shall be made by the
                          Committee, whose determination in that respect shall
                          be final, binding and conclusive. Except as expressly
                          provided herein, no issue by the Company of shares of
                          stock of any class, or securities convertible into
                          shares of stock of any class, shall affect (and no
                          adjustment by reason thereof shall be made with
                          respect to) the number and price of Receipts subject
                          to an Option or the number or price of related Option
                          Shares.

                   (ii)   The Committee may, if it so determines in the exercise
                          of its sole discretion, also make provision for
                          adjusting the number of Receipts or number or class of
                          securities underlying Receipts covered by any Option,
                          as well as the price paid therefor, in the event of
                          the Company's effecting one or more reorganizations,
                          recapitalizations, rights offerings, or other
                          increases or reductions of the number of Shares of its
                          outstanding Stock, or in the event of the Company's
                          consolidation with or merger into any other
                          corporation.

                  (iii)   Unless otherwise determined by the Board, upon the  
                          dissolution or liquidation of the Company, the Options
                          granted hereby shall terminate and thereupon become
                          unexercisable, null and void. Optionees shall be given
                          not less than ten (10) days' notice of an anticipated
                          dissolution or liquidation and exercisability of each
                          outstanding Option shall be accelerated so that the
                          Optionee may within such period exercise up to the
                          entire unexercised portion of his or her Option.
                          Optionees shall not be entitled hereunder to any
                          payment, severance, consideration or damages
                          whatsoever as a result of such dissolution or
                          liquidation.

         (g)      Disability of Optionee. In the event of an Optionee's 
                  Disability during the Term of an Option, any vested Option
                  held by the Optionee at the time of Disability may be
                  exercised at any time within one (1) year following the date
                  of Disability to the extent that the Optionee was entitled to
                  exercise the Option at the date of the Disability provided
                  that such Optionee is at the time of such Disability, or was
                  within the 90-day period prior thereto, an Employee of the
                  Company in Continuous Employment of the Company from the date
                  of the grant of the Option until the date of such Disability,
                  and provided further that no Option may be exercised after the
                  expiration of the term of the Option.

         (h)      Retirement of Option. In the event of the Retirement of an  
                  Optionee during the Term of a vested Option, such Option may
                  be exercised by the Optionee at any time within ninety (90)
                  days following the Retirement date to the extent that the
                  Optionee was entitled to exercise the Option at the time of
                  his or her retirement; provided that such Optionee is at the
                  time of such Retirement, or was within the 90-day period
                  immediately prior thereto, an Employee of the Company in
                  Continuous Employment with the Company from the date of the
                  grant of the Option until the date of Retirement; and provided
                  further that no Option may be exercised after the expiration
                  of the Term of the Option.

         (i)      Death of Optionee. In the event of the death of an Optionee
                  during the Term of a vested Option, the Option may be
                  exercised by the estate or other legal representative of the
                  Optionee for a period of up to one (1) year following the
                  Optionee's date of death to the extent that the Optionee was
                  entitled to exercise the Option at the time of the death
                  provided that no Option may be exercised after the expiration
                  of the Term of the Option.

         (j)      Optionee's Termination for Cause. In the event that an
                  Optionee is terminated as an Employee of the Company for Cause
                  during the Term of an Option, all Options previously granted
                  to the Employee shall immediately terminate and become
                  unexercisable, null and void, and no Receipts for Option
                  Shares shall be issued with respect to any Option held by the
                  Optionee.

         (k)      Other Termination. Unless otherwise determined by the 
                  Committee at or after a grant of an Option, if an Optionee
                  shall cease to be an Employee for any reason other than
                  Disability, Retirement, death, or for Cause, such individual's
                  Option shall automatically terminate; provided that, if the
                  Optionee is involuntarily terminated without Cause, any vested
                  Options held by such Optionee may be exercised for the lesser
                  of three months or the balance of such Option's Term. Except
                  as specifically set forth herein, all Options held by an
                  Employee shall automatically terminate and no longer be
                  exercisable as of the date of such Employee's termination of
                  employment with the Company.


         (l)      Change in Control. An Option Agreement may contain provisions
                  for accelerated vesting of the Option upon certain
                  circumstances arising subsequent to a change 


                                       8
<PAGE>   9


                  in control of or over the Company. The existence and terms and
                  conditions of such provisions shall be at the sole and
                  absolute discretion of the Committee as determined at the time
                  the Option is granted and set forth in the applicable Option
                  Agreement.

         (m)      Tax Withholding.  When an Optionee is required to pay to the 
                  Company an amount with respect to income or employment tax
                  withholding obligations in connection with the exercise of an
                  Option granted under the Plan, the Optionee may elect, prior
                  to the date the amount of such withholding is determined (the
                  "Tax Date") to make such payment, or an increased payment by
                  delivering cash or irrevocably directing the Trust to withhold
                  from the Receipts, which would otherwise be issued upon
                  exercise of the Option, such number of Receipts representing
                  Option Shares having a Fair Market Value equal to the amount
                  of tax required or elected to be withheld (a "Withholding
                  Election"). If an Optionee's Tax Date is deferred beyond the
                  date of exercise and the Optionee makes a Withholding
                  Election, the Optionee will receive the full number of
                  Receipts otherwise issuable upon exercise of the Option minus
                  the number of Receipts necessary to satisfy his or her minimum
                  withholding requirements measured on the date the Option is
                  exercised (or such higher payment as he or she may have
                  elected to make) with adjustments to be made in cash after the
                  Tax Date. Optionees shall be responsible for any income or
                  other taxes triggered by the grant, exercise or transfer of
                  Options and for any such taxes resulting from the Trust's sale
                  of Option Shares.

8.       NON-TRANSFERABILITY OF OPTIONS AND RECEIPTS FOR OPTION SHARES.

         (a)      Options. An Option may not be sold, pledged, assigned,
                  hypothecated, transferred or disposed of in any manner other
                  than by will or by the laws of descent and distribution and
                  may be exercised, during the lifetime of the Optionee, only by
                  the Optionee. If the Option Agreement permits, the Optionee
                  may designate a beneficiary who may (i) exercise an Option
                  under Section 7(d) above, or (ii) receive Receipts for Option
                  Shares issued pursuant to the exercise of an Option where the
                  death of an Optionee occurs between the date on which the
                  Optionee exercises the Option and the date the Company issues
                  the Receipt.

         (b)      Receipts and Option Shares.

                  (i)     The Committee may impose such other restrictions on
                          Receipts and Option Shares as it deems advisable. The
                          certificates, if any, representing the Receipts or
                          Option Shares shall bear a legend which shall give
                          notice of such restrictions on the transferability of
                          the such Receipts or Option Shares.

                  (ii)    Except as otherwise provided by the Committee, if 
                          there is no public market for the Option Shares at the
                          time the Optionee wishes to sell any Receipts, the
                          Optionee shall first offer to sell such Receipts to
                          the Purchase Office at the Fair Market Value of the
                          Option Shares represented 



                                       9
<PAGE>   10

                          by such Receipts. If the Purchase Office fails to
                          accept the offer to purchase such Receipts within
                          forty-five (45) days after receipt of such offer, the
                          Optionee shall be free to sell or transfer such
                          Receipts in compliance with applicable law. If the
                          Optionee does not sell or transfer such Receipts
                          within ninety (90) days, then the Optionee may not
                          sell such Receipts without again offering the Receipts
                          to the Purchase Office pursuant to the terms of this
                          Paragraph. If the Purchase Office accepts the
                          Optionee's initial or later offer(s), the Purchase
                          Office shall pay the Optionee the purchase price for
                          all accepted Receipts within thirty six (36) months of
                          the Receipts tendered payable, such payment to be made
                          in four equal annual installments commencing on the
                          date of such acceptance by the Purchase Office. The
                          Purchase Office may make payments for purchasing the
                          Receipts in cash, stock of Global TeleSystems Group,
                          Inc. (provided its stock is publicly traded) or both.
                          Determinations by the Purchase Office whether to
                          accept the offer of an Optionee to purchase Receipts
                          shall be made by the Committee.

                  (iii)   If there is a public market for the Option Shares,
                          then the Receipts shall be freely transferable by the
                          Optionee to the extent permitted by applicable law.

9.       TIME OF GRANTING OPTIONS. Unless otherwise specified by the Committee,

or modification shall increase the number of Shares subject to the Plan or add
any material rights or modifications to Options under the Plan. The Committee
may amend the Plan from time to time to ensure the Plan's compliance with
applicable securities laws, regulations or rulings. Any amendment or termination
of the Plan, other than any amendment required by applicable securities laws,
regulations or rulings, shall not affect Options already granted; and such
Options shall remain in full force and effect as if the Plan had not been
amended or terminated.

11.      CONDITIONS UPON ISSUANCE OF RECEIPTS, OPTION SHARES. Notwithstanding
anything to the contrary herein, Receipts shall not be issued unless the
exercise of the associated Option and the issuance and delivery of such Receipts
pursuant thereto shall comply with all relevant provisions of law and the
