                                      FOR
                 ALL OUTSTANDING 11 1/2% SENIOR NOTES DUE 2007
 
     THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK TIME ON
               , 1997, UNLESS EXTENDED, PROVIDED IT MAY NOT BE EXTENDED BEYOND
               , 1997.
 
   
    Hermes Europe Railtel B.V., a company organized in the Netherlands ("HER" or
the "Company"), hereby offers, upon the terms and subject to conditions set
forth in this Prospectus (the "Prospectus") and the accompanying Letter of
Transmittal (the "Letter of Transmittal"; together with the Prospectus, the
"Exchange Offer"), to exchange up to an aggregate principal amount of
$265,000,000 of its registered 11 1/2% Senior Notes due 2007 (the "Exchange
Notes") for up to an aggregate principal amount of $265,000,000 of its
outstanding unregistered 11 1/2% Senior Notes due 2007 (the "Outstanding
Notes"). The form and terms of the Exchange Notes are identical in all material
respects to those of the Outstanding Notes, except for certain transfer
restrictions and registration rights relating to the Outstanding Notes and
except for certain interest provisions related to such registration rights. The
Exchange Notes will be issued pursuant to, and entitled to the benefits of, the
Indenture (as defined) governing the Outstanding Notes. The Exchange Notes and
the Outstanding Notes are sometimes referred to collectively as the "Notes."
    
 
   
    The Exchange Notes will be general unsecured obligations of the Company and
will rank senior in right of payment to all future Indebtedness (as defined)of
the Company that is expressly subordinated in right of payment to the Exchange
Notes and pari passu in right of payment with all existing and future unsecured
liabilities of the Company that are not so subordinated. The Exchange Notes will
be effectively subordinated to all secured liabilities of the Company to the
extent of the assets securing such liabilities. In addition, the Exchange Notes
will be structurally subordinated to all liabilities (including trade payables)
of the Company's subsidiaries. As of September 30, 1997, the Company had no
Indebtedness other than the Outstanding Notes, and the Company's subsidiaries
had $19.0 million of total liabilities reflected on the Company's balance sheet.
During and following the Exchange Offer, the Company intends to transfer all or
substantially all of its assets and liabilities (other than the Exchange Notes)
to its subsidiaries. After such transfer, the Company will be a holding company
with limited assets and will operate its business through subsidiaries. See
"Capitalization" and "Description of the Exchange Notes."
    
 
    The Company will accept for exchange any and all Outstanding Notes which are
properly tendered in the Exchange Offer prior to 5:00 p.m., New York time, on
             , 1997, unless extended by the Company in its sole discretion (the
"Expiration Date"). The Exchange Offer will not in any event be extended to a
date beyond              , 1997. Tenders of Outstanding Notes may be withdrawn
at any time prior to 5:00 p.m., New York time, on the Expiration Date. If the
Company terminates the Exchange Offer and does not accept for exchange any
Outstanding Notes with respect to the Exchange Offer, the Company will promptly
return the Outstanding Notes to the holders thereof. The Exchange Offer is not
conditioned upon any minimum principal amount of Outstanding Notes being
tendered for exchange, but is otherwise subject to certain customary conditions.
The Outstanding Notes may be tendered only in integral multiples of $1,000.
 
    Interest on the Exchange Notes will be payable semiannually in cash on
February 15 and August 15 of each year, commencing February 15, 1998. Holders of
the Exchange Notes will receive interest on February 15, 1998, from the date of
initial issuance of the Exchange Notes, plus an amount equal to the accrued
interest on the Outstanding Notes from the later of (i) the most recent date to
which interest has been paid thereon and (ii) the date of issuance of the
Outstanding Notes, to the date of exchange thereof. The Exchange Notes will
mature on August 15, 2007. The Exchange Notes will be redeemable, in whole or in
part, at the option of the Company, at any time on or after August 15, 2002 at
the redemption prices set forth herein, plus accrued and unpaid interest to the
date of redemption. In addition, on or prior to August 15, 2000, the Company may
redeem Exchange Notes at a price in cash equal to 111.5% of the principal amount
thereof, plus accrued and unpaid interest to the date of redemption with the net
cash proceeds of one or more Public Equity Offerings (as defined) or Strategic
Equity Investments (as defined); provided, however, that at least two-thirds of
the principal amount of Exchange Notes originally issued remains outstanding
after each such redemption. Upon the occurrence of a Change of Control (as
defined), each holder of Exchange Notes will have the right to require the
Company to purchase such holder's Exchange Notes

     SEE "RISK FACTORS" BEGINNING ON PAGE 11 FOR CERTAIN INFORMATION THAT SHOULD
BE CONSIDERED IN CONNECTION WITH THE EXCHANGE OFFER.
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
                            ------------------------
            THE DATE OF THIS PROSPECTUS IS                  , 1997.

at a price in cash equal to 101% of the principal amount thereof, plus accrued
and unpaid interest to the date of purchase.
 
    The Exchange Notes are being offered hereunder in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreement dated
August 19, 1997 (the "Registration Rights Agreement") between the Company and
Donaldson, Lufkin & Jenrette Securities Corporation, UBS Securities LLC and
Lehman Brothers Inc., as the initial purchasers (the "Initial Purchasers") with
respect to the initial sale of the Outstanding Notes. The Outstanding Notes were
sold by the Company (the "Offering") on August 19, 1997 to the Initial
Purchasers who placed the Outstanding Notes with certain institutional investors
in reliance on certain exceptions under the Securities Act of 1933, as amended
(the "Securities Act"). Based on positions taken by the staff of the Securities
and Exchange Commission (the "Commission") that have been enunciated in
no-action letters issued in Exxon Capital Holdings Corp. (available April 13,
1989) and Morgan Stanley & Co. Inc. (available June 5, 1991), among others, the
Company believes that the Exchange Notes issued pursuant to the Exchange Offer
in exchange for Outstanding Notes may be offered for resale, resold and
otherwise transferred by the respective holders thereof (other than any such
holder which is (i) a broker-dealer who purchased such Outstanding Notes
directly from the Company to resell pursuant to Rule 144A or any other available
exemption under the Securities Act or (ii) an "affiliate" of the Company within
the meaning of Rule 405 under the Securities Act), without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the Exchange Notes are acquired in the ordinary course of such holder's
business and such holder has no arrangement with any person to participate in
the distribution of such Exchange Notes and is not engaged in and does not
intend to engage in a distribution of the Exchange Notes. However, the
Commission has not considered the Exchange Offer in the context of a no-action
letter and there can be no assurance that the staff of the Commission would make
a similar determination with respect to the Exchange Offer. Holders of
Outstanding Notes wishing to accept the Exchange Offer must represent to the
Company that such conditions have been met. Holders who tender Outstanding Notes
in the Exchange Offer with the intention to participate in a distribution of the
Exchange Notes may not rely upon the Morgan Stanley or similar no-action
letters. Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of the Exchange Notes received in exchange for Outstanding Notes if
such Exchange Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 180 days after the Expiration Date, it will make this
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."
 
    Any Outstanding Notes not tendered and accepted in the Exchange Offer will
remain outstanding and will be entitled to all the rights and preferences and
will be subject to the limitations applicable thereto under the Indenture.
Following consummation of the Exchange Offer, the holder of Outstanding Notes
will continue to be subject to the existing restrictions upon transfer thereof
and the Company will have no further obligation to such holders to provide for
the registration under the Securities Act of the Outstanding Notes held by them.
If the Company has exchanged Exchange Notes for all Outstanding Notes validly
tendered and not withdrawn in accordance with the terms of the Exchange Offer
and the Registration Statement remains effective until the expiration date of
the Exchange Offer, none of the Notes will be entitled to the contingent
increase in interest rate provided pursuant to the Registration Rights
Agreement.
 
    Prior to the Exchange Offer, there has been no public market for the
Exchange Notes. There can be no assurance as to the liquidity of any markets
that may develop for the Exchange Notes, the ability of holders to sell the
Exchange Notes or the price at which holders would be able to sell the Exchange
Notes. The Company does not intend to list the Exchange Notes for trading on any
U.S. national securities exchange or over-the-counter market system, but the
Outstanding Notes are eligible for trading in the Private Offerings, Resales and
Trading through Automated Linkages ("PORTAL") market and the Company expects to
list the Exchange Notes on the Luxembourg Stock Exchange. Future trading prices
of the Exchange Notes will depend on many factors, including among other things,
prevailing interest rates, the Company's operating results and the market for
similar securities. Historically, the market for securities similar to the
Exchange Notes, including non-investment grade debt, has been subject to
disruptions that have caused substantial volatility in the prices of such
securities. There can be no assurance that any market for the Exchange Notes, if
such market develops, will not be subject to similar disruptions. The Initial
Purchasers have advised the Company that they currently intend to make a market
in the Exchange Notes offered hereby. However, the Initial Purchasers are not
obligated to do so and any market making may be discontinued at any time without
notice.
 
    To comply with the securities laws of certain jurisdictions, it may be
necessary to qualify for sale or register the Exchange Notes prior to offering
or selling such Exchange Notes. The Company has agreed, pursuant to the
Registration Rights Agreement and subject to certain specified limitations
therein, to register or qualify the Exchange Notes held by broker-dealers for
offer or sale under the securities or blue sky laws of such jurisdictions as any
such holder reasonably requests in writing. Unless the Company is so requested,
the Company does not intend to take any action to register or qualify the
Exchange Notes for sale in any such jurisdictions.
 
    The Company will not receive any proceeds from the Exchange Offer. The
Company has agreed to pay certain expenses incident to the Exchange Offer.

    THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT

    NO DEALER, SALESPERSON OR OTHER INDIVIDUAL HAS BEEN AUTHORIZED TO GIVE ANY
INFORMATION OR MAKE ANY REPRESENTATION NOT CONTAINED IN THIS PROSPECTUS IN

IN ANY JURISDICTION WHERE, OR TO ANY PERSON TO WHOM, IT IS UNLAWFUL TO MAKE SUCH
OFFER OR SOLICITATION. NEITHER THE DELIVERY OF THIS PROSPECTUS, NOR ANY
DISTRIBUTION OF SECURITIES MADE HEREUNDER SHALL, UNDER ANY CIRCUMSTANCES, CREATE
ANY IMPLICATION THAT THERE HAS NOT BEEN ANY CHANGE IN THE FACTS SET FORTH IN
THIS PROSPECTUS OR IN THE AFFAIRS OF THE COMPANY SINCE THE DATE HEREOF.

                             AVAILABLE INFORMATION
 
     The Company has filed with the Securities and Exchange Commission (the
"Commission") a Registration Statement on Form S-4 (the "Registration
Statement," which term shall include all amendments, exhibits, annexes and
schedules thereto) under the Securities Act, and the rules and regulations
promulgated thereunder, covering the Exchange Notes being offered hereby. This
Prospectus does not contain all the information set forth in the Registration
Statement, certain parts of which are omitted in accordance with the rules and
regulations of the Commission. For further information with respect to the
Company and the Exchange Notes offered hereby, reference is made to the
Registration Statement, including the exhibits thereto, and financial statements
and notes filed as a part hereof. Statements made in this Prospectus concerning
the contents of any document referred to herein are not necessarily complete.
With respect to each such document filed with the Commission as an exhibit to
the Registration Statement, reference is made to the exhibit for a more complete
description of the matter involved, and each such statement shall be deemed
qualified in its entirety by such reference. The Registration Statement and the
exhibits and schedules thereto and reports and other information filed by the
Company with the Commission may be inspected at the public reference facilities
maintained by the Commission at Room 1024, 450 Fifth Street, N.W., Washington,
D.C. 20549, or at its regional offices located at the Citicorp Center, 500 West
Madison Street, Suite 1400, Chicago, Illinois 60661 and 7 World Trade Center,
13th Floor, New York, New York 10007. In addition, reports and other information
filed by the Company can be accessed via the Commission's Internet home page at
http://www.sec.gov/. Copies of such material also can be obtained from the
Public Reference Section of the Commission at 450 Fifth Street, N.W.,
Washington, D.C. 20549, at prescribed rates.
 
     The Company has agreed to file with the Commission, to the extent
permitted, and distribute to holders of the Exchange Notes reports, information
and documents specified in Section 13(a) and 15(d) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), so long as the Exchange Notes are
outstanding, whether or not the Company is subject to such informational
requirements of the Exchange Act.
 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
     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 Prospectus, and
particularly in the risk factors set forth herein under "Risk Factors." 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 roll-out of the
Company's Network (as defined), the Company's substantial leverage and the
Company's need for substantial additional capital requirements. These and other
factors are discussed herein under "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business" and
elsewhere in this Prospectus.
 
     The risk factors described herein 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 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.

                             SERVICE OF PROCESS AND
                      ENFORCEABILITY OF CIVIL LIABILITIES
 
   
     The Company is a Netherlands company and substantially all of its assets
are located outside the United States. In addition, certain members of the
Supervisory Board of the Company are residents of countries other than the
United States. As a result, it may not be possible for investors to effect
service of process within the United States upon such persons or to enforce
against such persons or the Company judgments of courts of the United States
predicated upon civil liabilities under the United States federal securities
laws. The Company has been advised by its Netherlands counsel, Loeff Claeys
Verbeke, that since there is no treaty between the United States and the
Netherlands providing for the reciprocal recognition and enforcement of
judgments, United States judgments are not enforceable in the Netherlands.
However, a final judgment for the payment of money obtained in a United States
court, which is not subject to appeal or any other means of contestation and is
enforceable in the United States, would in principle be upheld by a Netherlands
court of competent jurisdiction when asked to render a judgment in accordance
with such final judgment by a United States court, without substantive
re-examination of the merits of the subject matter thereof; provided that such
judgment has been rendered by a court of competent jurisdiction, in accordance
with rules of proper procedure, that it has not been rendered in proceedings of
a penal or revenue nature and that its content and possible enforcement are not
contrary to public policy or public order of the Netherlands. Notwithstanding
the foregoing, there can be no assurance that United States investors will be
able to enforce against the Company, or members of the Management or Supervisory
Boards, or certain experts named herein who are residents of the Netherlands or
other countries outside the United States, any judgments in civil and commercial
matters, including judgments under the federal securities laws. In addition,
there is doubt as to whether a Netherlands court would impose civil liability on
the Company or on the members of the Management or Supervisory Boards in an
original action predicated solely upon the federal securities laws of the United
States brought in a court of competent jurisdiction in the Netherlands against
the Company or such members.
    
 
     The Company is organized in the Netherlands and the Company's executive
offices are currently located at Terhulpsesteenweg 6A, 1560 Hoeilaart, Belgium,

                                  THE COMPANY
 
   
     Hermes Europe Railtel B.V. is developing an approximately 18,000 kilometer,
pan-European high capacity fiber optic network (the "HER Network" or the
"Network") designed to interconnect a majority of the largest Western and
Central European cities. 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
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"). HER intends to offer
these target customers a better transport system than is currently available in
Europe with a higher and more consistent level of transmission quality,
redundancy, network functionality and service at lower prices.
    
 
   
     HER began initial trials of the Brussels-Amsterdam portion of the Network
in the third quarter of 1996 and commenced commercial service in November 1996.
The Company expects to continue to roll out full telecommunications transport
service linking the cities of London, Rotterdam, Amsterdam, Antwerp, Brussels,
Paris, Dusseldorf and Frankfurt (the "initial five country network") in the
second quarter of 1998. The initial five country network is expected to consist
of 2,900 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 Network. Network coverage is
planned to be expanded to include Geneva, Zurich and Milan in the third quarter
of 1998. Additional extensions of the Network to be completed in phases through
the year 2000 will be built out into Scandinavia, Southern and Central Europe.
The HER Network is expected to have points of presence in at least 32 cities in
15 European countries (the "HER Geographical Area" or "HERGA"). HER is deploying
the Network along the rights-of-way of several of its rail-based shareholders as
well as the rights-of-way of a variety of alternative sources, including
motorways, waterways, pipelines and utilities.
    
 
     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 ("EC") adopted a directive (the "Full Competition Directive")
requiring the full liberalization of all telecommunications services in most
European Union ("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. These New Entrants will
seek to provide a more diverse offering of telecommunications services that are
priced competitively, that offer higher value added services to customers, and
that are accompanied by a high level of customer service. The Company 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. The Company 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 HER 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 one PTO therefore owns or controls
end-to-end cross-border circuit capacity. Consequently, the tariff for
cross-border switched voice traffic is determined by a series of bilateral
settlement agreements between PTOs. This system, known as the accounting rate
mechanism (the "ARM"),
    
 
                                        1

is highly complex and has kept the price of cross-border calls at levels
significantly higher than the underlying cost of transport and terminating
calls. Increasing competition, however, is forcing PTOs and New Entrants to
explore alternative means of transporting switched voice traffic across borders.
Full liberalization in 1998 will allow the PTOs and New Entrants to transport
this traffic across borders using dedicated circuits such as those provided by
the Company. The alternative for the transport of this traffic will be for these
competing carriers 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 will make the Company's
service offering attractive to these carriers. In particular, building 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. Significant among these is
obtaining the rights of way along which to construct fiber optic cable across
national borders as these typically do not meet at the border crossing. Those
that do meet are often not available on both sides. 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.
 
   
     The Company intends to address these deficiencies by creating a single
pan-European fiber network that will provide cross-border wholesale transport
services exclusively to the carrier market. The Company believes it is the only
operator currently developing such a network for this purpose. The HER Network
will provide the following advantages: the Network will (i) be wholly controlled
and operated by HER, allowing full end-to-end quality control, (ii) operate on a
low cost structure, which, combined with its ability to carry traffic from a
large number of carriers, will allow the Company to offer highly competitive
pricing, (iii) feature a network architecture and technology platform that will
allow for flexible network availability, full redundancy, high bandwidth speeds,
and low error performance and (iv) allow the Company to provide tailored
innovative service offerings to individual customers, allowing them to maximize
the efficiency of their own networks. The Company believes that these features
combined with the Company's early entry into the market, its carriers' carrier
strategy and the Company's current agreements and relationships with rail-based
entities will provide it with a sustainable competitive advantage.
    
 
     The Company's target customers carry a mixture of switched voice traffic,
data traffic and multimedia/image traffic. In 1995, the HERGA is estimated to
have generated in excess of 13 billion minutes of switched voice traffic with an
estimated value of approximately $9.4 billion, and to have required
approximately 5,900 E1 equivalents of circuit capacity. The market for switched
telecommunications traffic grew at 12% per annum from 1984 to 1992. The Company
expects this growth rate to continue through the year 2000 due to increased
demand for such services resulting from lower prices and the availability of new
services. Demand for switched voice capacity is expected by the Company to reach
11,300 E1 equivalents of circuit capacity by the year 2000. The market for data
traffic (which is currently carried primarily over IPLCs) is estimated to have
required approximately 250 E1 equivalents of circuit capacity in 1995. The
Company expects this market to grow at approximately 30% per annum due to the
increase in managed data network and other data services and to reach some 930
E1 equivalents of circuit capacity by the year 2000. The market for multimedia
and image traffic (primarily Internet traffic) is estimated to have required
approximately 180 E1 equivalents of circuit capacity in 1995. The Company
expects this market to grow at approximately 40% per annum primarily due to the
increase in Internet users and the increase in demand for high bandwidth
services and to reach some 970 E1 equivalents of circuit capacity by the year
2000.
 
   
     The Company has entered into agreements for the construction and/or lease
of the fiber optic routes for the initial five country network, except for some
of the routes in Germany which are currently under negotiation. The Company has
completed the construction of two undersea cables connecting the United Kingdom
to the Netherlands and to Belgium, which were placed in commercial service in
January 1998. In France, the Company has reached agreement with an operator of
motorways for the use of approximately 600 kilometers of infrastructure in
northern France, and has agreements with other providers to complete the French
segment of the initial five country network. The Company expects to start
commercial service connecting Paris to Brussels, Amsterdam and London by January
1998. Contracts have been concluded with respect to the portion of the Network
connecting Germany with each of France, the Netherlands and Switzerland.

     Currently, 16 customers are under contract for service on the HER Network.
These customers represent a range of telecommunications providers including
PTOs, a global consortium of PTOs, Internet service providers, an international
carrier, a value added network and resellers.
    
 
   
     The HER Network is 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 and bandwidth speeds
and error performance not otherwise available to carriers for transport of
telecommunications traffic across national borders in Europe. The Network is
designed to provide customers with a wide variety of network bandwidth speeds,
ranging from VC12/E1 Standard (equivalent to 2.048 Mbps) to STM-1/E4 Standard
(equivalent to 155 Mbps). The Network architecture specifies a meshed topology
that can reach destinations through multiple paths. Substantially all Network
equipment and control equipment will be owned by the Company. For all routings,
there will be at least two alternate paths. The Company expects to size the HER
Network through successive upgrades so that the Network has at least twice the
amount of capacity it is forecast to require in any given year. Network capacity
upgrades can be accomplished optically through the use of wave division
multiplexing ("WDM") technology without adding fiber optic cable. The HER
Network has been designed to be controlled by a single network management center
and supported by advanced operational support systems. The Network Operations
Center located in Brussels, Belgium and a 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.
    
 
   
     As of September 30, 1997, the Company will have had $103.2 million of cash
equity contributed by its shareholders. See "Certain Relationships and Related
Transactions." Based on the Company's business plan, the total capital
expenditures required for the HER Network are currently expected to be
approximately $335 million, with approximately $100 million required for the
rollout of the initial five country network. As of September 30, 1997,
approximately $27.3 million has been spent on Network capital expenditures. The
Company currently estimates that after the Offering, its capital resources will
be sufficient to fund operations and expected Network development through
December 1998. The Company expects that its operations will generate positive
EBITDA in the first year of full operation of the initial five country network.
Further, the Company does not expect that its operations will generate positive
cash flows from operations in the first year of full operation of the initial
five country network. Sources of capital to fund Network development after 1998
may include internally generated funds, bank debt and vendor financing.
    
 
   
     HER is owned approximately 79% by Global TeleSystems Group, Inc. ("GTS")
through its wholly-owned subsidiary, GTS-Hermes, Inc. ("GTS-Hermes"),
approximately 13% by HIT Rail B.V. ("HIT Rail"), a consortium of eleven European
railways, and approximately 8%, collectively, by two of the railways that
comprise the HIT Rail consortium. GTS is a U.S. based provider of a broad range
of telecommunications services to businesses, other telecommunications service
providers and consumers in Russia and the Commonwealth of Independent States,
Western and Central Europe and Asia. The Notes are obligations of the Company
only and are not guaranteed by, and do not otherwise constitute obligations of,
GTS.

             CONSEQUENCES OF FAILURE TO EXCHANGE OUTSTANDING NOTES
 
     Holders of Outstanding Notes who do not exchange their Outstanding Notes
for Exchange Notes pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer of such Outstanding Notes as set forth in the
legends thereon as a consequence of the issuance of the Outstanding Notes
pursuant to exemptions from, or in transactions not subject to the registration
requirements of the Securities Act and applicable state securities laws.
Accordingly, such Outstanding Notes may be resold only (i) to a person whom the
seller reasonably believes is a qualified institutional buyer (as defined in
Rule 144A under the Securities Act) in a transaction meeting the requirements of
Rule 144A, (ii) in a transaction meeting the requirements of Rule 144 under the
Securities Act, (iii) outside the United States to a foreign person in a
transaction meeting the requirements of Rule 904 under the Securities Act or
(iv) in accordance with another exemption from the registration requirements of
the Securities Act (and upon an opinion of counsel if the Company so requests),
(v) to the Company or (vi) pursuant to an effective registration statement, and,
in each case, in accordance with any applicable securities laws of any state of
the United States or any other applicable jurisdiction. The Company does not
currently anticipate that it will register the Outstanding Notes under the
Securities Act. See "Risk Factors -- Consequences of Failure to Exchange
Outstanding Notes" and "Terms of the Exchange Offer -- Consequences of Failure
to Exchange."

                                         payment to all future Indebtedness of
                                         the Company that is expressly
                                         subordinated in right of payment to the

                                         that are not so subordinated. The

                                         subordinated to any secured liabilities

                                         assets securing such liabilities. In

                                         structurally subordinated to all
                                         liabilities (including trade payables)
                                         of the Company's subsidiaries. As of

                                         the Company's subsidiaries had $19.0
                                         million of total liabilities reflected
                                         on the Company's balance sheet. During

                                         substantially all of its assets and
                                         liabilities (other than the Exchange
                                         Notes) to its subsidiaries. After such
                                         transfer, the Company will be a holding
                                         company with limited assets and will
                                         operate its business through
                                         subsidiaries. See "Capitalization" and

                                         approximately $56.5 million of the net
                                         proceeds of the offering of Outstanding
                                         Notes to acquire the Pledged
                                         Securities. The Pledged Securities have
                                         been pledged to the Trustee for the
                                         benefit of the holders of the Exchange
                                         Notes and deposited into an escrow
                                         account (the "Escrow Account") held by
                                         an escrow agent for the benefit of the
                                         Trustee and the holders of the Exchange
                                         Notes in accordance with an escrow
                                         agreement. Funds may be disbursed from
                                         the Escrow Account for interest
                                         payments on the Exchange Notes. Upon
                                         acceleration of the maturity of the
                                         Exchange Notes, the Escrow Agreement
                                         will provide for the payment of the
                                         amount remaining in the Escrow Account
                                         to the Trustee to be applied on account
                                         of amounts owing on the Exchange Notes
                                         as provided in the Indenture. Pending
                                         such disbursement, any uninvested funds
                                         contained in the Escrow Account will be
                                         invested in Cash Equivalents (as
                                         defined). See "Description of the
                                         Exchange Notes -- Escrow Account."
 
Optional Redemption.................     The Exchange Notes will be redeemable,
                                         in whole or in part, at the option of
                                         the Company, at any time on or after
                                         August 15, 2002 at the redemption

                                         plus accrued and unpaid interest to the

                                         Investments; provided, however, that at
                                         least two-thirds of the principal
                                         amount of Exchange Notes originally
                                         issued remains outstanding after each
                                         such redemption.
 
                                         The Company may, at any time, at its
                                         option, redeem all (but not less than
                                         all) of the Exchange Notes then
                                         outstanding at 100% of the principal
                                         amount thereof, plus accrued and unpaid
                                         interest, if any, to the date of
                                         redemption, if the Company has become
                                         or would become obligated to pay, on
                                         the next date on which any amount would
                                         be payable with respect to the Exchange
                                         Notes, any Additional Amounts (as
                                         defined) as a result of change in law
                                         (including any regulations promulgated
                                         thereunder) or in the interpretation or
                                         administration thereof, if such change
                                         is announced and becomes effective on
                                         or after the date of original issuance
                                         of the Outstanding Notes on or about
                                         August 19, 1997 (the "Issue Date" or
                                         the "Closing Date").
 
Change of Control...................     Upon the occurrence of a Change of
                                         Control, each holder of Exchange Notes
                                         will have the right to require the
                                         Company to purchase all or any portion
                                         of such holder's Exchange Notes at a
                                         price in cash equal to 101% of the
                                         principal amount thereof, plus accrued
                                         and unpaid interest to the date of
                                         purchase. There can be no assurance
                                         that the Company will have the
                                         financial resources necessary to
                                         purchase the Exchange Notes upon a
                                         Change of Control.

                                         (the "Indenture") contains covenants
                                         that limit the ability of the Company

- ------------------------------
 
(1) Although the Company was formed on July 6, 1993, the Company had no
    operations prior to 1994.
   
(2) EBITDA is earnings (loss) from operations before interest, taxes,
    depreciation and amortization. EBITDA is a measure of a company's
    performance commonly used in the telecommunications industry, but should not
    be construed as an alternative to net income (loss) determined in accordance
    with generally accepted accounting principles ("GAAP") as an indicator of
    operating performance or as an alternative to cash from operating activities
    determined in accordance with GAAP as a measure of liquidity. See line items
    "Net cash used in operating activities," "Net cash used in investing
    activities" and "Net cash provided by financing activities" on pages F-5 and
    F-18 of the Company's consolidated financial statements for disclosure of
    cash flows from operating, investing and financing activities.
    
   
(3) Because of the Company's historic losses, the Company has experienced a
    deficiency of earnings to fixed charges throughout its existence. The
    deficiency of earnings to fixed charges equals the loss from continuing
    operations before income taxes minus fixed charges. Fixed charges consist of
    interest on all indebtedness.

                                  RISK FACTORS
 
     An investment in the Notes offered hereby involves a high degree of risk.
Prospective participants in the Exchange Offer should consider carefully the
following factors in evaluating the Company and its business in addition to the
other information contained in this Prospectus.
 
   
RISKS RELATING TO HER NETWORK ROLL-OUT
    
 
   
     The Company's ability to achieve its strategic objective will depend in
large part on the successful, timely and cost-effective completion of the
Network. Although the Company currently operates commercially over the
Amsterdam-Brussels portion of the Network, the development of the remainder of
the Network may be delayed or adversely affected by a variety of factors,
uncertainties and contingencies. Many of these factors, such as strikes, natural
disasters and other casualties, are beyond the Company's control. In addition,
HER will need to negotiate and conclude additional agreements with various
parties regarding, among other things, rights-of-way and development and
maintenance of the Network infrastructure and equipment. Historically, the
Company 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 the Company of
substantial amounts of additional capital and financing (see "-- Substantial
Additional Capital Requirements"), (ii) timely performance by various third
parties of their contractual obligations to engineer, design and construct
portions of the Network and (iii) the Company's ability to obtain and maintain
applicable governmental approvals (see "-- Government Regulation").
    
 
   
     The Company expects to roll out full telecommunications service over the
initial five country network in the second quarter of 1998, and the 18,000
kilometer network to be operational during the year 2000. Although the Company
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 Network could have a material adverse effect on the Company, including
its ability to make payments on the Notes.
 
SUBSTANTIAL LEVERAGE
 
   
     The Company is highly leveraged. After the HER Recapitalization and the
Offering and the application of the proceeds thereof, at September 30, 1997, the
Company had total long-term debt of $265.4 million and total shareholders'
equity of $63.0 million. The Company had negative EBITDA of $15.7 million and
$13.4 million for the year ended December 31, 1996 and for the nine months ended
September 30, 1997, respectively. See "Capitalization" and "Selected
Consolidated Financial Data." The Indenture and certain debt instruments to
which the Company is a party limit but do not prohibit the incurrence of
additional indebtedness by the Company. Under the Indenture, the Company will be
able to and may incur a substantial amount of secured indebtedness in order to
complete the build-out of its Network. The Company expects to incur substantial
additional indebtedness in the future and that a substantial amount of its
vendor financing will be on a secured basis.
    
 
   
     The Company's ability to pay the principal of and interest on its
indebtedness will depend upon the Company's future performance, which is subject
to a variety of factors, uncertainties and contingencies, many of which are
beyond the Company's control. There can be no assurance that the Company will
generate sufficient cash flow in the future to enable it to meet its anticipated
debt service requirements (including those with respect to the Notes). Failure
to generate sufficient cash flow may impair the Company's ability to raise
additional equity or debt financing or to meet its debt service requirements,
including the payment obligations under the Notes, and to complete development
of the HER Network. In such circumstances, the Company may be required to
renegotiate the terms of the instruments relating to its long-term debt or to
refinance all or a portion thereof. There can be no assurance that the Company
would be able to renegotiate successfully such terms or refinance its
indebtedness when required or that the terms of any such refinancing would be
acceptable to management.
    
 
                                       11
<PAGE>   18
 
   
     The Company's leverage could result in adverse consequences to the holders
of the Notes. Such consequences may include, among other things: (i) certain of
the future borrowing by the Company may be at variable rates of interest that
could cause the Company to be vulnerable to increases in interest rates; (ii)
the Company may be more leveraged than certain of its competitors, which may
place it at a competitive disadvantage with respect to such competitors; (iii)
the Company's vulnerability to the effects of general economic downturns or to
delays or increases in the costs of developing the HER Network may be increased;
(iv) the Company's ability to take advantage of significant business
opportunities that may arise may be impaired; and (v) the Company's ability to
respond to changes affecting the implementation of its financing, construction,
development or operating plans may be impaired. The discretion of the Company's
management with respect to certain business matters will be limited by covenants
contained in the Indenture and future debt instruments. Among other things, the
covenants contained in the Indenture restrict, condition or prohibit the Company
from incurring additional indebtedness, creating liens on its assets, making
certain asset dispositions or entering into transactions with affiliates. There
can be no assurance that the Company's leverage and such restrictions or
restrictions in other debt instruments applicable to the Company will not
materially and adversely affect the Company's ability to finance its future
operations or capital needs or to engage in other business activities. Moreover,
a failure to comply with the obligations contained in the Indenture or any
future debt instrument could result in an event of default under such
agreements, which could permit acceleration of the related debt and acceleration
of debt under future debt agreements that may contain cross-acceleration or
cross-default provisions.
    
 
SUBSTANTIAL ADDITIONAL CAPITAL REQUIREMENTS
 
   
     Based on the Company's business plan, the total capital expenditures
required for the HER Network are currently expected to be approximately $335
million, with approximately $100 million required for the rollout of the initial
five country network. As of September 30, 1997, approximately $27.3 million has
been spent on Network capital expenditures. As of September 30, 1997, HER has
cash of $237.5 million available for operations and to construct and develop the
Network. Additional financing will be required to develop the Network. Under the
Indenture, the Company will be able to and may incur a substantial amount of
secured indebtedness in order to complete the build-out of its Network. The
Company expects that a substantial amount of its vendor financing will be on a
secured basis. Failure to obtain necessary financing may require the Company to
delay or abandon its plans for deploying the remainder of the Network, which may
have a material adverse effect on the Company, including its ability to make
payments on the Notes.
    
 
   
     The Company's revenues and the cost of rolling out its Network and
operating its business will depend upon a variety of factors including, among
other things, the Company'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 HER
Network, (iv) access markets and attract sufficient numbers of customers and (v)
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 development of the Network. See
"-- Government Regulation," "-- Competition," "-- Technology," and "-- Risks
Relating to HER Network Roll-out." 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 the Company's future capital
requirements. Accordingly, there can be no assurance that the amount of funds
required to complete the Network will not exceed the anticipated amounts
described above. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Use of Proceeds."
    
 
LIMITED OPERATING HISTORY; HISTORY OF OPERATING LOSSES AND WORKING CAPITAL
DEFICITS
 
   
     HER was considered a development stage enterprise through December 31,
1996. The Company's prospects must be considered in light of the risks,
expenses, problems and delays inherent in establishing a new business in a
rapidly changing industry. While the Company has commenced commercial operation
of the Brussels-Amsterdam portion of the Network, the Company has generated only
limited revenue, has limited experience in operating its business and intends to
enter countries where it has limited or no operating
    
 
                                       12
<PAGE>   19
 
experience. The Company's plans and development of the Network have been
substantially delayed in the past.
 
   
     The Company's business has generated operating losses and, as yet,
insufficient cash flow to meet its future debt service requirements, capital
expenditures and other cash needs. At September 30, 1997, the Company had a
cumulative net loss of $39.8 million and a working capital balance of $257.5
million. There can be no assurance that the Company will be able to achieve or
sustain operating profitability, or generate sufficient cash flow to make
payments on the Notes.
    
 
ANTICIPATED HOLDING COMPANY STRUCTURE; EFFECTIVE SUBORDINATION OF THE NOTES;
DEPENDENCE UPON CASH FLOW OF SUBSIDIARIES
 
     The Notes will be general unsecured obligations of the Company and will
rank senior in right of payment to all future Indebtedness of the Company that
is expressly subordinated in right of payment to the Notes and pari passu in
right of payment with all existing and future unsecured liabilities of the
Company that are not so subordinated. See "Description of Certain Indebtedness"
and "Use of Proceeds."
 
   
     During and following the Exchange Offer, the Company intends to transfer
all or substantially all of its assets and liabilities (other than the Notes) to
subsidiaries. After such transfer, the Company will be a holding company with
limited assets and will operate its business through subsidiaries. Accordingly,
the Company will rely entirely upon distributions from its subsidiaries to
generate the funds necessary to meet its obligations, including payments on the
Notes. Such subsidiaries will be separate and distinct legal entities which have
no obligation, contingent or otherwise, to pay any amount due pursuant to the
Notes or to make any funds available therefor, whether by dividends, loans or
other payments. Any right of the Company and its creditors, including holders of
the Notes, to participate in the assets of any of the Company's subsidiaries
upon any liquidation or administration of any such subsidiary will be subject to
the prior claims of the creditors of such subsidiary. The claims of creditors of
the Company, including holders of the Notes, will be effectively subordinated to
all existing and future third-party indebtedness and liabilities, including
trade payables, of the Company's subsidiaries. The Company and its subsidiaries
may incur other debt in the future, including secured debt.
    
 
     The Company expects that future indebtedness incurred by it may be secured,
particularly through equipment financings. As a result, any claims against the
Company will be effectively subordinated to indebtedness secured by mortgages or
other security interests or liens on the assets of the Company, which could have
material consequences to holders of the Notes. Such security may include
substantially all of the fixed assets of the Company. The value of a substantial
portion of such fixed assets is derived from employing such assets in a
telecommunications business. These assets are highly specialized and, taken
individually, can be expected to have limited marketability. Consequently, in
the event of a realization by secured creditors on the assets of the Company,
creditors would likely seek to sell the business as a going concern in order to
maximize the proceeds realized. The price obtained upon any such sale could be
adversely affected by the necessity to obtain approval of the sale or permits
from the applicable regulatory authorities and to comply with other applicable
governmental regulations.
 
UNCERTAINTY OF MARKET ACCEPTANCE; POTENTIAL LACK OF CUSTOMER DEMAND
 
     The Company only recently began delivering services to a limited number of
customers over a portion of the Network. Since there is no precedent for a
pan-European carriers' carrier network, the market acceptance and customer
demand for services over such a network are uncertain. There can be no assurance
that the Company will be able to achieve the traffic volume necessary to realize
the anticipated cash flow, operating efficiencies and cost benefits of the
Network.
 
GOVERNMENT REGULATION
 
     As a multinational telecommunications company, the Company is subject to
varying degrees of regulation in each of the jurisdictions in which it provides
services. Local laws and regulations, and the interpretation of such laws and
regulations, differ significantly among the jurisdictions in which the Company
operates. 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
 
                                       13
<PAGE>   20
 
regard to the Company's 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.
 
     A substantial portion of the Company's strategy is based upon the timely
implementation of regulatory liberalization of the EU telecommunications market
on January 1, 1998 under existing 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, the Company faces the risk
that it will establish the 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 the Company's ability to
provide certain services. Furthermore, national governments may not necessarily
pass legislation implementing an EC directive in the form 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, the
Company'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 the
Company's operations by preventing the Company from establishing its Network as
currently intended, as well as a material adverse effect on the Company's
ability to make payments on the Notes.
 
   
     The Company has obtained licenses, authorizations and/or registrations in
the United Kingdom, Belgium, the Netherlands and Germany. The Company has filed
an application for authorization in France and is awaiting final approval
thereof. In addition, the Company 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 these licenses may limit or otherwise
affect the Company's scope of operations. 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 in the future can be obtained by the Company. The loss of, or failure
to obtain, these telecommunications licenses or a substantial limitation upon
the terms of these telecommunications licenses could have a material adverse
effect on the Company. See "Licenses and Regulatory Issues."
    
 
NEED TO OBTAIN AND MAINTAIN INFRASTRUCTURE PROVIDER AND RIGHTS-OF-WAY
AGREEMENTS; DEPENDENCE ON LEASED FIBER
 
   
     The Company 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 the Company 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 on the Company's business. In
addition, the Company depends on third parties for leases of dark fiber for
portions of its Network. There can be no assurance that the Company 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 the Company's business.

<PAGE>   21
 
COMPETITION
 
     The European and international telecommunications industries are
competitive. The Company is providing "point-to-point" transborder services, and
upon completion of the Brussels-Amsterdam-London ring of the initial five
country network, will begin to offer "virtual infrastructure" services. See
"Business -- Services." The Company believes that there is currently no
competition for the provision of virtual infrastructure services on a
pan-European centrally managed network, although the Company faces potential
competition from other telecommunications companies who may develop centrally
managed pan-European networks. PTOs, multinational telecommunications carriers,
other telecommunications developers and certain niche telecommunications
providers could proceed to build a competitive network. Such competition could
have a material adverse effect on the Company and its ability to make payments
on the Notes. WorldCom, Inc. recently announced plans to construct a
pan-European fiber network, the first phase of which is expected to connect
London, Amsterdam, 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.
 
     The Company competes with respect to its "point-to-point" transborder
service offering against circuits currently provided by PTOs through IPLCs.
Although the Company believes that it has certain competitive advantages over
PTOs in this market, there can be no assurance that the Company will compete
effectively against PTOs, which have established customer bases and greater
technical, financial, marketing and other resources.
 
     The Company believes that liberalization of the European telecommunications
market is likely to attract entrants to the market. Many of the Company's
current or potential competitors have technical, financial, marketing and other
resources substantially greater than those of the Company. There can be no
assurance that the Company will be able to overcome successfully the competitive
pressures to which it is or may become subject, both in the markets in which it
currently operates and in markets into which it might expand. See
"Business -- Competition."
 
MANAGING RAPID GROWTH
 
   
     As a result of the Company's expected growth and expansion, significant
demands will be placed on the Company's management, operational and financial
resources and on its systems and controls. In order to manage its growth
effectively, the Company must continue to develop 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 its
operations. There can be no assurance that the Company will be able to develop
and operate the entire HER Network as currently planned, expand into additional
markets at the rate currently 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 demands on
the Company's customer support, sales and marketing and administrative resources
and Network infrastructure. There can be no assurance that the operating and
financial control systems and infrastructure of the Company will be adequate to
maintain and effectively manage future growth. 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.
    
 
DEPENDENCE ON SIGNIFICANT CUSTOMERS
 
     Telecommunications companies constitute, and will continue to constitute,
the Company's customer base. The Company may become dependent on a small number
of significant customers. The loss of a significant customer may have a material
adverse effect on the Company and its ability to make payments on the Notes.
 
                                       15
<PAGE>   22
 
CURRENCY AND EXCHANGE RISKS
 
   
     The Company's functional and reporting currencies are the Belgian franc and
the U.S. dollar, respectively. The Company conducts and will continue to conduct
business transactions in currencies other than its functional and reporting
currencies; accordingly, appreciation or depreciation in the value of other
currencies as compared to the functional currency or reporting currency could
result in a material transaction or translation gain or loss, respectively. The
Company experienced a foreign currency gain of $0.1 million for the nine months
ended September 30, 1997 and a foreign currency loss of $0.8 million for the
nine months ended September 30, 1996. The Company experienced a $1.1 million
foreign currency transaction loss for the year ended December 31, 1996. The
Company operates in a multi-currency environment and is subject to the effects
of fluctuations in exchange rates. The Company transacts its business in the
following significant currencies: the Belgian franc and the European Currency
Unit. The Company is in the process of developing risk management policies that
will establish guidelines for managing foreign exchange risk. The Company
expects that these policies will be implemented in the first quarter of 1998 and
anticipates that these policies will allow management to use financial hedging
instruments to manage foreign exchange exposure. Currently, the Company is
considering alternatives to hedge foreign exchange exposure resulting from the
issuance of the Outstanding Notes.
    
 
     The Company has not entered into hedging transactions to limit its foreign
currency risk exposure, although the Company may implement such practices in the
future. In addition, the Company's revenues have been, and the Company currently
expects that its revenues will be, generated primarily in the ECU while the
interest and principal payment obligations with respect to the Notes will be
payable in U.S. dollars. Accordingly, the Company is subject to the risk that it
will be unable to generate a sufficient amount of ECU-based revenue to meet its
principal and interest obligations with respect to the Notes.
 
RISK OF ERROR IN FORWARD LOOKING STATEMENTS
 
   
     HER is a development stage company. All statements in this Prospectus that
are not clearly historical in nature are forward looking. Examples of such
forward looking statements include the statements concerning HER's operations,
prospects, markets, technical capabilities, funding needs, financing sources,
commercial operations schedule and future regulatory approvals, as well as
information concerning expected characteristics of competing systems and
expected actions of third parties such as equipment suppliers and partners.
These forward looking statements are inherently predictive and speculative and
no assurance can be given that any of such statements will prove to be correct.
Actual results and developments may be materially different from those expressed
or implied by such statements. Prospective investors should carefully review the
other risk factors set forth in this section of the Prospectus for a discussion
of various factors which could result in any of such forward looking statements
proving to be inaccurate.
    
 
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 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, the Company's
ability to upgrade technology from this platform to WDM may be important in
establishing and/or maintaining a cost advantage over competitive carriers.
While the current operational network segment has performed at or above design
specifications since November 1996, there can be no assurance that the HER
Network will achieve the technical specifications for which it was designed or
that the Company will be able to upgrade the Network as technological
improvements in telecommunications
    
 
                                       16
<PAGE>   23
 
   
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 the Company.
    
 
ENFORCEABILITY OF JUDGMENTS
 
     All of the assets of the Company 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 U.S. court against the assets of the
Company, including in order to foreclose upon such assets. In addition, it may
not be possible for investors to: (i) effect service of process within the
United States upon the Company or (ii) enforce U.S. court judgements against
such persons obtained in such courts predicated upon U.S. federal securities
laws. See "Service of Process and Enforceability of Civil Liabilities."
 
LACK OF PUBLIC MARKET
 
     The Exchange Notes will constitute a new issue of securities with no
established trading market. There can be no assurance as to the liquidity of
markets that may develop for the Exchange Notes or the ability of holders of the
Exchange Notes to sell them, or the prices at which such holders would be able
to sell the Exchange Notes. If such markets were to exist, the Exchange Notes
could trade at prices that may be lower than the initial market values thereof
depending on many factors, including prevailing interest rates, the Company's
operating results and the markets for similar securities. The Company does not
intend to apply for listing of the Exchange Notes on any securities exchange
(other than the Luxembourg Stock Exchange) or for inclusion of the Exchange
Notes in any automated quotation system. The Exchange Notes are expected to be
eligible for trading in the PORTAL market. Accordingly, there can be no
assurance as to the development or liquidity of any market for the Exchange
Notes. Historically, the market for non-investment grade debt has been subject
to disruptions that have caused substantial volatility in the prices of
securities similar to the Exchange Notes. There can be no assurance that, if a
market for the Exchange Notes were to develop, such a market would not be
subject to similar disruptions. See "Description of the Exchange
Notes -- Exchange Offer; Registration Rights; Additional Interest" and "Plan of
Distribution."
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each holder of Notes will be
entitled to require the Company to purchase any or all of the Notes held by such
holder at the prices stated herein. However, the Company's ability to repurchase
the Notes upon a Change of Control may be limited by the terms of then existing
contractual obligations of the Company and its subsidiaries. In addition, the
Company may not have adequate financial resources to effect such a purchase, and
there can be no assurance that the Company would be able to obtain such
resources through a refinancing of the Notes to be purchased or otherwise. If
the Company fails to repurchase all of the Notes tendered for purchase upon the
occurrence of a Change of Control, such failure will constitute an Event of
Default under the Indenture.
 
     With respect to the sale of assets referred to in the definition of Change
of Control, the phrase "all or substantially all" as used in such definition
varies according to the facts and circumstances of the subject transaction, has
no clearly established meaning under the relevant law and is subject to judicial
interpretation. Accordingly, in certain circumstances there may be a degree of
uncertainty in ascertaining whether a particular transaction would involve a
disposition of "all or substantially all" of the assets of a person and
therefore it may be unclear whether a Change of Control has occurred and whether
the Notes are subject to an offer to purchase.
 
     The Change of Control provision may not necessarily afford the holders
protection in the event of a highly leveraged transaction, including a
reorganization, restructuring, merger or other similar transaction involving the
Company that may adversely affect the holders, because such transactions may not
involve a shift in voting power or beneficial ownership or, even if they do, may
not involve a shift of the magnitude required under the definition of Change of
Control to trigger such provisions. Except as described under "Description of
the Notes -- Change of Control," the Indenture does not contain provisions that
permit the holders of the Notes
 
                                       17
<PAGE>   24
 
to require the Company to repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction.
 
RELIANCE ON KEY PERSONNEL
 
     The Company's operations are managed by a small number of key executive
officers, the loss of any of whom could have a material adverse effect on the
Company. The Company believes that its growth and future success will depend in
large part on its continued ability to attract and retain highly skilled and
qualified personnel. The competition for qualified personnel in the
telecommunications industry is intense and, accordingly, there can be no
assurance that the Company will be able to hire or retain necessary personnel.
The loss of senior management or the failure to recruit additional qualified
personnel in the future could significantly impede attainment of the Company's
financial, Network development, marketing and other objectives. Although the
Company has designed incentive and compensation programs to retain key employees
and has entered into employment agreements with certain executive officers, no
assurance can be given as to the continued availability of qualified key
executive officers. See "Management."
 
COUNTRY AND EUROPEAN COMMUNITY ECONOMIC, POLITICAL AND LEGAL CONSIDERATIONS
 
     All of the Company's investments have been, and are expected to continue to
be, in Europe. Risks include loss of or damage to property from terrorism and
other political risks (such as the risks of increases in taxes or changes in law
or governmental regulation).
 
RELATIONSHIP WITH GTS; POTENTIAL CONFLICTS OF INTEREST
 
     As of the date hereof, GTS beneficially owns approximately 79% of the
outstanding capital stock of the Company through GTS-Hermes Inc., a wholly owned
subsidiary, which is the sole Managing Director of the Company. In either case,
however, GTS, through GTS-Hermes, Inc., will be a majority shareholder of the
Company and will have the ability to strongly influence and/or control the
affairs and business of the Company. Circumstances may occur in which the
interests of GTS could be in conflict with the interests of the holders of the
Notes. In addition, GTS may have an interest in pursuing transactions that, in
its judgment, enhance the value of its equity investments in the Company, even
though such transactions may involve risks to the holders of the Notes. There
can be no assurance that any such conflicts of interests will be resolved in
favor of such holders of the Notes. See "Security Ownership of Principal
Shareholders and Management."
 
ESCROW ARRANGEMENTS
 
     Although the Escrow Account is designed to secure a portion of the
Company's obligations under the Notes, the ability to deal freely with the funds
in the Escrow Account following an Event of Default under the Indenture may be
limited by applicable bankruptcy, reorganization, receivership, insolvency,
liquidation or other similar legislation or legal principles. See "Description
of the Notes -- Escrow Account."
 
CONSEQUENCES OF FAILURE TO EXCHANGE OUTSTANDING NOTES
 
     Holders of Outstanding Notes who do not exchange their Outstanding Notes
for Exchange Notes pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer of such Outstanding Notes as set forth in the
legend thereon as a consequence of the issuance of the Outstanding Notes
pursuant to exemptions from, or in transactions not subject to, the registration
requirements of the Securities Act and applicable state securities laws. In
general, the Outstanding Notes may not be offered or sold, unless registered
under the Securities Act and applicable state securities laws, or pursuant to an
exemption therefrom. Except under certain limited circumstances, the Company
does not intend to register the Outstanding Notes under the Securities Act. In
addition, any holder of Outstanding Notes who tenders in the Exchange Offer for
the purpose of participating in a distribution of the Exchange Notes may be
deemed to have received restricted securities and, if so, will be required to
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. To the extent
Outstanding Notes are tendered and accepted in the Exchange Offer, the trading
market, if any, for the Outstanding Notes not tendered could be adversely
affected. See "The Exchange Offer" and "Description of the Exchange
Notes -- Registration Rights."

<PAGE>   25
 
                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby. In consideration for issuing the Exchange Notes
as contemplated herein, the Company will receive in exchange Outstanding Notes
in like principal amount. The Outstanding Notes surrendered in exchange for the
Exchange Notes will be retired and cancelled and cannot be reissued.
Accordingly, issuance of the Exchange Notes will not result in any change in the
indebtedness of the Company.
 
   
     The net proceeds received by the Company from the Offering, after deducting
the underwriting discounts and commissions and estimated expenses of the
Offering, are approximately $251.8 million. The net proceeds of the Offering
will be used, together with the $51.8 million equity contribution from
GTS-Hermes (described below), to complete the development and operational
start-up of the initial five country network and the full 18,000 kilometer
Network and for general working capital purposes. As of September 30, 1997, the
Company has spent approximately $27.3 million on Network capital expenditures.
The Company's sources of liquidity through the end of September 1997 have been
capital contributions totaling $2.9 million in the form of common equity and
shareholder loans totaling $48.5 million, which were converted into common
equity upon the finalization of the HER Recapitalization. Additional cash
proceeds of approximately $51.8 million were contributed (the "GTS
Contribution") as common equity, on September 30, 1997, by GTS-Hermes pursuant
to the HER Recapitalization.
    
 
                          TERMS OF THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     The Outstanding Notes were sold by the Company on August 19, 1997 to the
Initial Purchasers who placed the Outstanding Notes with certain institutional
investors in reliance on Section 4(2) and Regulation S of, and Rule 144A under,
the Securities Act. In connection with the sale of the Outstanding Notes, the
Company entered into the Registration Rights Agreement, pursuant to which the
Company agreed to use its best efforts to consummate an offer to exchange the
Outstanding Notes for the Exchange Notes pursuant to an effective registration
statement within 90 days of August 19, 1997. A copy of the Registration Rights
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part. Unless the context requires otherwise, the term
"holder" with respect to the Exchange Offer means any person in whose name
Outstanding Notes are registered on the books of Company or any other person who
has obtained a properly completed bond power from the registered holder, or any
person whose Outstanding Notes are held of record by DTC who desires to deliver
such Outstanding Notes by book-entry transfer at DTC.
 
     The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the
Exchange Notes issued pursuant to the Exchange Offer in exchange for the
Outstanding Notes may be offered for sale, resold or otherwise transferred by
any holder without compliance with the registration and prospectus delivery
provisions of the Securities Act. Based on interpretations by the staff of the
Commission set forth in no-action letters issued to third parties, the Company
believes that Exchange Notes issued pursuant to the Exchange Offer in exchange
for Outstanding Notes may be offered for resale, resold and otherwise
transferred by any holder of such Exchange Notes (other than any such holder
that is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act and except in the case of broker-dealers, as set forth below)
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such Exchange Notes are acquired in the
ordinary course of such holder's business and such holder has no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes. Any holder who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes or who is an affiliate of
the Company may not rely on such interpretation by the staff of the Commission
and must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any secondary resale transaction. Each
broker-dealer that receives Exchange Notes for its own account in exchange for
Outstanding Notes, where such Outstanding Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "Plan of Distribution."
 
                                       19
<PAGE>   26
 
     By tendering in the Exchange Offer, each holder of Outstanding Notes will
represent to the Company that, among other things, (i) the Exchange Notes
acquired pursuant to the Exchange Offer are being obtained in the ordinary
course of business of the person receiving such Exchange Notes, whether or not
such person is such holder, (ii) neither the holder of Outstanding Notes nor any
such other person has an arrangement or understanding with any person to
participate in the distribution of such Exchange Notes, (iii) if the holder is
not a broker-dealer, or is a broker-dealer but will not receive Exchange Notes
for its own account in exchange for Outstanding Notes, neither the holder nor
any such other person is engaged in or intends to participate in the
distribution of such Exchange Notes and (iv) neither the holder nor any such
other person is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act or, if such holder is an "affiliate," that such holder
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable.
 
     Following the consummation of the Exchange Offer, holders of Outstanding
Notes not tendered will not have any further registration rights and the
Outstanding Notes will continue to be subject to certain restrictions on
transfer. Accordingly, the liquidity of the market for the Outstanding Notes
could be adversely affected.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept for exchange any and
all Outstanding Notes properly tendered and not withdrawn prior to 5:00 p.m.,
New York time, on the Expiration Date. The Company will issue $1,000 principal
amount of Exchange Notes in exchange for each $1,000 principal amount of
Outstanding Notes surrendered pursuant to the Exchange Offer. Outstanding Notes
may be tendered only in integral multiples of $1,000.
 
     The form and terms of the Exchange Notes will be the same as the form and
terms of the Outstanding Notes, except that the Exchange Notes will be
registered under the Securities Act and hence will not bear legends restricting
the transfer thereof. The Exchange Notes will evidence the same debt as the
Outstanding Notes. The Exchange Notes will be issued under and entitled to the
benefits of the Indenture, which also authorized the issuance of the Outstanding
Notes, such that both series will be treated as a single class of debt
securities under the Indenture.
 
     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Outstanding Notes being tendered for exchange. Holders of Outstanding
Notes do not have any appraisal or dissenters' rights in connection with the
Exchange Offer.
 
     As of the date of this Prospectus, $265,000,000 aggregate principal amount
of the Outstanding Notes are outstanding. This Prospectus, together with the
Letter of Transmittal, is being sent to all registered holders of Outstanding
Notes. There will be no fixed record date for determining registered holders of
Outstanding Notes entitled to participate in the Exchange Offer.
 
     The Company intends to conduct the Exchange Offer in accordance with the
provisions of the Registration Rights Agreement and the applicable requirements
of the Exchange Act, and the rules and regulations of the Commission thereunder.
Outstanding Notes which are not tendered for exchange in the Exchange Offer will
remain outstanding and continue to accrue interest and will be entitled to the
rights and benefits such holders have under the Indenture and the Registration
Rights Agreement.
 
     The Company shall be deemed to have accepted for exchange properly tendered
Outstanding Notes when, as and if the Company shall have given oral or written
notice thereof to the Exchange Agent and complied with the applicable provisions
of the Registration Rights Agreement. The Exchange Agent will act as agent for
the tendering holders for the purposes of receiving the Exchange Notes from the
Company. The Company expressly reserves the right to amend or terminate the
Exchange Offer, and not to accept for exchange any Outstanding Notes not
theretofore accepted for exchange, upon the occurrence of any of the conditions
specified below under "-- Certain Conditions to the Exchange Offer."
 
     Holders who tender Outstanding Notes in the Exchange Offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the Letter of Transmittal, transfer taxes with respect to
 
                                       20
<PAGE>   27
 
the exchange of Outstanding Notes pursuant to the Exchange Offer. The Company
will pay all charges and expenses, other than certain applicable taxes described
below, in connection with the Exchange Offer. See "The Exchange Offer -- Fees
and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York time on
            , 1997, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended. The Exchange Offer will
not in any event be extended beyond             , 1997.
 
     In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and will mail to the registered
holders of Outstanding Notes an announcement thereof, each prior to 9:00 a.m.,
New York time, on the next business day after the then Expiration Date.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting for exchange any Notes, to extend the Exchange Offer or to terminate
the Exchange Offer if any of the conditions set forth below under "-- Certain
Conditions to the Exchange Offer" shall not have been satisfied, by giving oral
or written notice of such delay, extension or termination to the Exchange Agent
or (ii) to amend the terms of the Exchange Offer in any manner. Any such delay
in acceptance, extension, termination or amendment will be followed as promptly
as practicable by oral or written notice thereof to the registered holders of
Outstanding Notes. If the Exchange Offer is amended in a manner determined by
the Company to constitute a material change, the Company will promptly disclose
such amendment by means of a prospectus supplement that will be distributed to
the registered holders, and the Company will extend the Exchange Offer,
depending upon the significance of the amendment and the manner of disclosure to
the registered holders, if the Exchange Offer would otherwise expire during such
period.
 
INTEREST ON THE EXCHANGE NOTES
 
     The Exchange Notes will bear interest at a rate of 11 1/2% per annum,
payable semi-annually, on each February 15 and August 15, commencing February
15, 1998. Holders of Exchange Notes will receive interest on February 15, 1998
from the date of initial issuance of the Exchange Notes, plus an amount equal to
the accrued and unpaid interest on the Outstanding Notes from the date of
initial issuance to the date of exchange thereof for Exchange Notes. Interest on
the Outstanding Notes accepted for exchange will cease to accrue upon issuance
of the Exchange Notes.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other term of the Exchange Offer, the Company will not
be required to accept for exchange, or exchange any Exchange Notes for, any
Outstanding Notes, and may terminate the Exchange Offer as provided herein
before the acceptance of any Outstanding Notes for exchange, if:
 
          (a) any action or proceeding is instituted or threatened in any court
     or by or before any governmental agency with respect to the Exchange Offer
     which, in the Company's reasonable judgment, might materially impair the
     ability of the Company to proceed with the Exchange Offer; or
 
          (b) any law, statute, rule or regulation is proposed, adopted or
     enacted, or any existing law, statute, rule or regulation is interpreted by
     the staff of the Commission, which, in the Company's reasonable judgment,
     might materially impair the ability of the Company to proceed with the
     Exchange Offer; or
 
          (c) any governmental approval has not been obtained, which approval
     the Company shall reasonably deem necessary for the consummation of the
     Exchange Offer as contemplated hereby.
 
     The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Outstanding Notes not theretofore
accepted for exchange, upon the occurrence of any of the conditions of the
Exchange Offer specified above. The Company will give oral or written notice of
any extension, amendment, non-acceptance or termination to the holders of the
Outstanding Notes as promptly as
 
                                       21
<PAGE>   28
 
practicable, such notice in the case of any extension to be issued no later than
9:00 a.m., New York time, on the next business day after the previously
scheduled Expiration Date.
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its reasonable judgment. The failure by the Company at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right, and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
     In addition, the Company will not accept for exchange any Outstanding Notes
tendered, and no Exchange Notes will be issued in exchange for any such
Outstanding Notes, if at such time any stop order shall be threatened or in
effect with respect to the Registration Statement of which this Prospectus
constitutes a part or the qualification of the Indenture under the Trust
Indenture Act of 1939.
 
PROCEDURES FOR TENDERING
 
     Only a holder of Outstanding Notes may tender such Outstanding Notes in the
Exchange Offer. To tender in the Exchange Offer, a holder must complete, sign
and date the Letter of Transmittal, or facsimile thereof, have the signature
thereon guaranteed if required by the Letter of Transmittal, and mail or
otherwise deliver such Letter of Transmittal or such facsimile to the Exchange
Agent prior to 5:00 p.m., New York time, on the Expiration Date. In addition,
either (i) Outstanding Notes must be received by the Exchange Agent along with
the Letter of Transmittal, or (ii) a timely confirmation of book-entry transfer
(a "Book-Entry Confirmation") of such Outstanding Notes, if such procedure is
available, into the Exchange Agent's account at The Depository Trust Company
(the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry
transfer described below must be received by the Exchange Agent prior to the
Expiration Date, or (iii) the holder must comply with the guaranteed delivery
procedures described below. To be tendered effectively, the Letter of
Transmittal and other required documents must be received by the Exchange Agent
at the address set forth below under "Exchange Agent" prior to 5:00 p.m., New
York time, on the Expiration Date.
 
     If delivery of the Outstanding Notes is to be made by book-entry transfer
to the account maintained by the Exchange Agent at DTC, the Letter of
Transmittal need not be manually executed; provided, however, that tenders of
Outstanding Notes must be effected in accordance with the procedures mandated by
DTC's Automated Tender Offer Program ("ATOP"). To tender Outstanding Notes
through ATOP, the electronic instructions sent to DTC and transmitted by DTC to
the Exchange Agent must contain the character by which the participant
acknowledges its receipt of and agrees to be bound by the Letter of Transmittal.
 
     The tender by a holder which is not withdrawn prior to the Expiration Date
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.
 
THE METHOD OF DELIVERY OF OUTSTANDING NOTES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE COMPANY.
HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR OTHER NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner whose Outstanding Notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct such
registered holder of Outstanding Notes to tender on such beneficial owner's
behalf. If such beneficial owner wishes to tender on such owner's own behalf,
such owner must, prior to completing and executing the Letter of Transmittal and
delivering such owner's Outstanding Notes, either make appropriate arrangements
to register ownership of the Outstanding Notes in such owner's name or
 
                                       22
<PAGE>   29
 
obtain a properly completed bond power from the registered holder of Outstanding
Notes. The transfer of registered ownership may take considerable time and may
not be able to be completed prior to the Expiration Date.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal described
below, as the case may be, must be guaranteed by an Eligible Institution (as
defined) unless the Outstanding Notes tendered pursuant thereto are tendered (i)
by a registered holder who has not completed the box entitled "Special Issuance
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. If signatures on a Letter of
Transmittal or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantor must be a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act which is a member of one of the recognized
signature guarantee programs identified in the Letter of Transmittal (an
"Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered holder of any Outstanding Notes listed therein, such Outstanding
Notes must be endorsed or accompanied by a properly completed bond power, signed
by such registered holder as such registered holder's name appears on such
Outstanding Notes with the signature thereon guaranteed by an Eligible
Institution.
 
     If the Letter of Transmittal or any Outstanding Notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Outstanding Notes and withdrawal of tendered
Outstanding Notes will be determined by the Company in its sole discretion,
which determination will be final and binding. The Company reserves the absolute
right to reject any and all Outstanding Notes not properly tendered or any
Outstanding Notes the Company's acceptance of which would, in the opinion of
counsel for the Company, be unlawful. The Company also reserves the right to
waive any defects, irregularities or conditions of tender as to particular
Outstanding Notes. The Company's interpretation of the terms and conditions of
the Exchange Offer (including the instructions in the Letter of Transmittal)
will be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of Outstanding Notes must be cured
within such time as the Company shall determine. Although the Company intends to
notify holders of defects or irregularities with respect to tenders of
Outstanding Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give such notification. Tenders of
Outstanding Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Outstanding Notes received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holders, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
     In all cases, issuance of Exchange Notes for Outstanding Notes that are
accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of Outstanding Notes or a timely Book-Entry
Confirmation of such Outstanding Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal and all other required documents. If any tendered Outstanding Notes
are not accepted for exchange for any reason set forth in the terms and
conditions of the Exchange Offer or if Outstanding Notes are submitted for a
greater principal amount than the holder desires to exchange, such unaccepted or
non-exchanged Outstanding Notes will be returned without expense to the
tendering holder thereof (or, in the case of Outstanding Notes tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer
Facility pursuant to the book-entry transfer procedures described below, such
non-exchanged Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration or
termination of the Exchange Offer.
 
                                       23
<PAGE>   30
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Outstanding Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Outstanding Notes by causing
the Book-Entry Transfer Facility to transfer such Outstanding Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility in accordance with
such Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Notes may be effected through book-entry transfer at the Book-Entry
Transfer Facility, the Letter of Transmittal or facsimile thereof, with any
required signature guarantees and any other required documents, must, in any
case, be transmitted to and received by the Exchange Agent at the address set
forth below under "Exchange Agent" on or prior to the Expiration Date or, if the
guaranteed delivery procedures described below are to be complied with, within
the time period provided under such procedures. Delivery of documents to the
Book-Entry Transfer Facility does not constitute delivery to the Exchange Agent.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Outstanding Notes and (i) whose
Outstanding Notes are not immediately available or (ii) who cannot deliver their
Outstanding Notes, the Letter of Transmittal or any other required documents to
the Exchange Agent prior to the Expiration Date, may effect a tender if:
 
          (a) The tender is made through an Eligible Institution;
 
          (b) Prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
     setting forth the name and address of the holder, the registered number(s)
     of such Outstanding Notes and the principal amount of Outstanding Notes
     tendered, stating that the tender is being made thereby and guaranteeing
     that, within three New York Stock Exchange trading days after the
     Expiration Date, the Letter of Transmittal (or facsimile thereof) together
     with the Outstanding Notes or a Book-Entry Confirmation, as the case may
     be, and any other documents required by the Letter of Transmittal will be
     deposited by the Eligible Institution with the Exchange Agent; and
 
          (c) Such properly completed and executed Letter of Transmittal (or
     facsimile thereof), as well as all tendered Notes in proper form for
     transfer or a Book-Entry Confirmation, as the case may be, and all other
     documents required by the Letter of Transmittal, are received by the
     Exchange Agent within three New York Stock Exchange trading days after the
     Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Outstanding Notes according to the
guaranteed delivery procedures set forth above.

and otherwise comply with the procedures of such facility. All questions as to
the validity, form and eligibility (including time of receipt) of such notices
will be determined by the Company, whose determination shall be final and
binding on all parties. Any Outstanding Notes so withdrawn will be deemed not to
have been validly tendered for exchange for purposes of the Exchange Offer. Any
Outstanding Notes which have been tendered for exchange but which are not
exchanged for any reason will be returned to the holder thereof without cost to
such holder (or, in the case of Outstanding Notes tendered by book-entry
transfer into the Exchange Agent's account at the Book-Entry Transfer Facility
pursuant to the book-entry transfer procedures described above, such Outstanding
Notes will be credited to an account maintained with such Book-Entry Transfer
Facility for the Outstanding Notes) as soon as practicable after withdrawal,

Outstanding Notes may be retendered by following one of the procedures described
under "-- Procedures for Tendering" above at any time on or prior to the
Expiration Date.

person other than the registered holder of Notes tendered, or if tendered Notes
are registered in the name of any person other than the person signing the
Letter of Transmittal, or if a transfer tax is imposed for any reason other than
the exchange of Notes pursuant to the Exchange Offer, then the amount of any
such transfer taxes (whether imposed on the registered holder or any other

CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Outstanding Notes who do not exchange their Outstanding Notes
for Exchange Notes pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer of such Outstanding Notes, as set forth in the
legend thereon, as a consequence of the issuance of the Outstanding Notes
pursuant to the exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In general, the Outstanding Notes may not be offered or sold, unless
registered under the Securities Act, except pursuant to an exemption from, or in
a transaction not subject to, the Securities Act and applicable state securities
laws. The Company does not currently anticipate that it will register the
Outstanding Notes under the Securities Act.

(2) EBITDA is earnings (loss) from operations before interest, taxes,
    depreciation and amortization. EBITDA is a measure of a company's
    performance commonly used in the telecommunications industry, but should not
    be construed as an alternative to net income (loss) determined in accordance
    with GAAP as an indicator of operating performance or as an alternative to
    cash from operating activities determined in accordance with GAAP as a
    measure of liquidity. See line items "Net cash used in operating
    activities," "Net cash used in investing activities" and "Net cash provided

    financial statements for disclosure of cash flows from operating, investing
    and financing activities.
    
 
   
(3) Because of the Company's historic losses, the Company has experienced a
    deficiency of earnings to fixed charges throughout its existence. The
    deficiency of earnings to fixed charges equals the loss from continuing
    operations before income taxes minus fixed charges. Fixed charges consist of
    interest on all indebtedness.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   
     The following is a discussion of the financial condition and results of
operations of the Company as of September 30, 1997 and 1996, December 31, 1996,
1995 and 1994 and for the nine months ended September 30, 1997 and 1996 and for
the years ended December 31, 1996, 1995 and 1994. The following discussion
should be read in conjunction with the Company's audited consolidated financial
statements, the notes related thereto and the other financial data included
elsewhere in this Prospectus. 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 revenue and costs and (iii) changes in the Company's competitive
environment, 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. Factors that
could cause such differences include, but are not limited to, those discussed
under "Risk Factors."
    
 
OVERVIEW
 
     The Company is a development stage enterprise and has invested heavily in
developing its Network. The Company realized a small stream of revenues in 1996
from its commencement of commercial service on the Amsterdam-Brussels portion of
its Network in November 1996. The Company expects that its operations will
generate positive EBITDA in the first year of full operation of the initial five
country network.
 
RESULTS OF OPERATIONS
 
   
  NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996
    
 
   
     Revenue.  For the nine months ended September 30, 1997, the Company
generated revenue of $2.3 million. This revenue was generated from the operation
of the Brussels to Amsterdam segment of the HER Network, which began commercial
operation in November 1996. There was no revenue generated from operations for
the nine months ended September 30, 1996.
    
 
   
     Gross Margin.  The Company had unfavorable gross margins of $(3.7) million
and $(3.4) million in the nine months ended September 30, 1997 and 1996,
respectively. The unfavorable margin was primarily due to higher depreciation on
Network assets related to the Brussels to Amsterdam segment which were
transferred from construction in process to telecommunications equipment at the
end of 1996.
    
 
   
     Selling, General and Administrative.  Selling, general and administrative
expenses were $11.6 million and $7.3 million for the nine months ended September
30, 1997 and 1996, respectively. The increase in selling, general, and
administrative expenses was due mostly to the increase in the number of
employees. The Company had 125 and 91 employees at September 30, 1997 and 1996,
respectively.
    
 
   
     Foreign Currency.  HER experienced foreign currency gains of $0.1 million
and foreign currency losses of $0.8 million for the nine months ended September
30, 1997 and 1996, respectively. The Company operates in a multi-currency
environment and is subject to the effects of fluctuations in exchange rates. See
"Risk Factors -- Currency and Exchange Risks."
    
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995 COMPARED
TO YEAR ENDED DECEMBER 31, 1994
 
   
     Revenue.  HER had minimal revenues for the year ended December 31, 1996 and
no revenues for the years ended December 31, 1995 and 1994.
    
 
   
     Gross Margin.  HER had an unfavorable gross margin of $(4.7) million for
the year ended December 31, 1996 and no gross margin for the years ended
December 31, 1995 and 1994.
    
 
     Selling, General and Administrative.  Selling, general and administrative
expenses were $10.6 million, $6.6 million and $0.2 million for the years ended
December 31, 1996, 1995 and 1994, respectively. In addition,
 
                                       29
<PAGE>   36
 
   
the Company had 101, 29 and 2 employees at December 31, 1996, 1995 and 1994,
respectively. The increase in selling, general and administrative expenses and
employees reflects HER's continued transition from the start-up phase to the
operational phase.
    
 
   
     Foreign Currency.  HER experienced a $1.1 million foreign currency
transaction loss for the year ended December 31, 1996. The Company operates in a
multi-currency environment and is subject to the effects of fluctuations in
exchange rates. See "Risk Factors -- Currency and Exchange Risks."
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The primary source of funding for HER through September 30, 1997 has been
cash equity contributions of $103.2 million and net proceeds from the Offering
of $251.8 million.
    
 
   
     Development of the HER fiber optic network is capital intensive. The
buildout of the Network is expected to require approximately $335 million of
capital expenditures, with approximately $100 million required for the initial
five country network. The Company currently estimates that after the Offering
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. The Company expects that its operations will generate positive
EBITDA in the first year of full operation of the initial five country network.
Further, the Company does not expect that its operations will generate positive
cash flows from operations in the first year of full operation of the initial
five country network. Sources of capital to fund Network development after 1998
may include internally generated funds, bank debt and vendor financing. The
Company is currently in discussion with a number of financial institutions to
obtain debt financing and to negotiate vendor financing with key suppliers of
network equipment.
    
 
  CAPITAL EXPENDITURES AND WORKING CAPITAL
 
   
     The development of the Company's business in the past has required
substantial capital expenditures. In the future, the Company will require
substantial capital expenditures significantly in excess of historical levels to
develop and expand the Network generally. The Company had negative working
capital balances of $0.4 million and $4.4 million as of December 31, 1995 and
1996, respectively, and a working capital balance of $257.5 million as of
September 30, 1997. The Company had an accumulated deficit of $39.8 million at
September 30, 1997 including net losses of approximately $16.0 million and $17.1
million for the periods ending December 31, 1996 and September 30, 1997,
respectively.
    
 
  LIQUIDITY ANALYSIS
 
   
     The Company had cash and cash equivalents of $237.5 million and $2.0
million at September 30, 1997 and December 31, 1996, respectively. The Company
had $57.0 million and $3.8 million of restricted cash at September 30, 1997 and
December 31, 1996, respectively, representing the Company's obligation to place
into escrow the first four scheduled semi-annual interest payments on the Notes
and cash held in escrow pursuant to an agreement with a major vendor.
    
 
   
     During the nine months ended September 30, 1997 and 1996, the Company's
operating activities used $12.3 million and $8.4 million of cash, respectively.
During the years ended December 31, 1996, 1995 and 1994, the Company used $11.9
million, $2.5 million and $0.2 million, respectively, of cash for operating
activities. Cash used for investing activities was $20.1 million, $4.6 million
and $0.1 million for the years ended December 31, 1996, 1995 and 1994,
respectively. The use of cash in operating and investing activities reflects the
developmental stage of the Company's commercial activities and the engineering
and equipment costs associated with the initial buildout of the fiber optic
network.

                               INDUSTRY OVERVIEW
 
   
     HER's primary service offering consists of high capacity cross-border
circuits in Europe for wholesale customers provided over an integrated, managed
pan-European Network. The Company expects that such customers will include PTOs
and New Entrants. These target customers carry a mixture of voice traffic, data
traffic and multimedia/image traffic. Historically European PTOs have
monopolized the provision of these telecommunications services resulting in high
prices and limited service for both carriers and end-users. The liberalization
in the European telecommunications market is creating more demand for
cross-border transport capacity through (i) the entry of increased numbers of,
and different types of, New Entrants to the market, (ii) increased end-user
demand for capacity due to the introduction of new services and for improved
quality, and (iii) increased use of existing services due to lower prices. HER
intends to capitalize on the opportunities arising from this large and
inefficient market as well as this increased demand for cross-border transport
capacity by being the first or among the first operators in the European market
to provide pan-European carrier's carrier services.
    
 
THE TELECOMMUNICATIONS SERVICES MARKET
 
   
     The telecommunications services market being addressed by HER target
customers can be divided broadly into three categories: voice traffic, data
traffic and multimedia/image traffic which includes Internet traffic.
    
 
     Voice Traffic.  In 1995 the HERGA is estimated to have generated in excess
of 13 billion minutes of international switched telecommunications traffic
("MITT") which both originate and terminate in the HERGA with a total value of
$9.4 billion. European international switched telecommunications traffic has
historically grown at a rate of approximately 12% annually from 1984 to 1992.
The table below summarizes the intra-HERGA MITTs by country which terminate
within the HERGA for 1995:

     The Company's basic service offering is wholesale transmission capacity
measured in E1 equivalents of circuit capacity. An E1 circuit is capable of
handling 30 simultaneous voice calls. Minutes of traffic may be translated into
E1 equivalent circuit capacity by calculating the average number of MITT per
minute and then making an adjustment for the uneven distribution of calls. In
1995, within the HERGA, there were approximately 13.4 billion MITT. This is
equivalent to an average of approximately 25,400 MITT per minute.This figure may
be divided by 30 to yield E1 equivalent circuits in use at a given time.
However, an
 
                                       31
<PAGE>   38
 
adjustment must be made to allow for the uneven distribution of calls, with peak
usage estimated at approximately 7 times average usage. Based on this algorithm,
the approximately 13.4 billion of intra-HERGA MITT generated in 1995 translate
into capacity requirements of approximately 5,900 E1 equivalent circuits. The
Company expects this capacity requirement to grow at a rate of approximately 14%
per year to some 11,300 E1 equivalent circuits of capacity in the year 2000. The
Company expects that the introduction of competition in the liberalizing
European market and its impact on pricing and infrastructure utilization will
drive the peak usage average up yielding this increase in the prospective growth
rate. In 1995, the total value of this traffic is estimated to have been $9.4
billion.
 
     Data Traffic.  In 1995 the market for data traffic within the HERGA is
estimated to have been about 250 E1 equivalent circuits, which the Company
expects will grow on the order of 30% per annum to approximately 930 E1
equivalent circuits in the year 2000. Driving the growth for data networks is
the expected increase in managed data network services and a transition from
private leased circuits to Virtual Private Networks.
 
     Multimedia/Image Traffic.  Multimedia/image traffic usage for 1995 is
estimated at approximately 180 E1 equivalents of circuit capacity with a rapidly
growing number of users. The Company expects a growth rate of approximately 40%
per annum resulting in traffic use of approximately 970 E1 equivalents of
circuit capacity in the year 2000. The increase in the growth rate is expected
primarily due to increased demand for and use of these services.
 
THE CURRENT EUROPEAN MARKET
 
     Current telecommunications service provided by PTOs is characterized by a
number of shortcomings. 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. PTOs therefore
do not own or control end-to-end cross-border circuit capacity. Pan-European
service has been provided through the networks of the PTOs linked by an
extensive system of multiple, point-to-point links. As a consequence cross-
border transport has been possible in only two ways: (i) either through the
transport and termination of traffic by the PTO under the bilateral ARM or (ii)
through the leasing by carriers or large businesses of IPLCs provided by PTOs.
 
     The ARM.  Under the ARM, international switched voice traffic is exchanged
under bilateral correspondent agreements between carriers in two countries.
Correspondent agreements provide for the termination of traffic in, and return
traffic to, the carriers' respective countries at negotiated accounting rates.
In addition, correspondent agreements provide for network coordination and
accounting and settlement procedures between the carriers. Both carriers are
responsible for their own costs and expenses related to operating their
respective halves of end-to-end international connection. The ARM, to which only
PTOs could be participants, has been responsible for keeping the price of
cross-border calls in Europe at levels significantly higher than the underlying
cost of transporting and terminating the calls. The continuing liberalization of
the telecommunications market is, however, putting increasing pressure on both
accounting rates and on the ARM itself.
 
     IPLCs.  IPLCs are private leased circuits that are provisioned on a
half-circuit basis through the networks of two or more PTOs. IPLCs may be
composed of a mix of circuit capacities (generally limited to low capacities) as
well as a mix of transmission technologies including PDH and SDH. The HERGA
includes six of the top ten IPLC routes in the world. Customers for IPLCs
include multinational corporations, PTOs, global consortia of telecommunications
operators and other carriers. IPLCs provided by PTOs have a number of inherent
disadvantages including high prices, lack of redundancy, lack of end-to-end
quality control, low quality due to diversity of network systems and equipment,
limited availability of bandwidth and long lead times for provisioning.
 
   
     The Company intends to address the above deficiencies by creating a single
pan-European fiber network that will provide cross-border wholesale transport
services exclusively to the carrier market for this purpose. The Company
believes it is the only operator currently developing such a network. The
Company's network will be wholly controlled and operated by HER, allowing full
end-to-end quality control. The Company's low
    
 
                                       32
<PAGE>   39
 
   
cost structure and its ability to load the network with traffic from a large
number of carriers will allow the Company to offer highly competitive pricing.
The HER network architecture and technology platform allows for flexible network
availability, full redundancy, high bandwidth speeds, and low error performance.
It will also allow the Company to provide tailored innovative service offerings
to individual customers, allowing them to maximize the efficiency of their own
networks. The Company believes that these features combined with the Company's
early entry into the market, its carriers' carrier strategy and the Company's
current agreements and relationships with rail-based entities will provide it
with competitive advantages.
    
 
  LIBERALIZATION OF THE EUROPEAN MARKET
 
     In Europe, the traditional system of monopoly PTOs has ensured the
development of broad access to telecommunications services; however, 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. The
inefficiencies of the traditional monopoly system combined with the EU
liberalization initiatives have created the current market opportunity for the
Company's service offerings.
 
     In March 1996, the European Commission adopted the Full Competition
Directive requiring the full liberalization of all telecommunications markets in
EU member states by January 1, 1998 with the exception of certain countries that
were granted an additional grace period. The Company expects that full
liberalization in Europe will lead to the emergence of multiple New Entrants
with new and competitive service offerings. Increasing competition is forcing
these PTOs and New Entrants to explore alternative means of transporting
switched voice traffic across borders in order to reduce the high costs
associated with the ARM. Full liberalization will allow the PTOs and New
Entrants to transport this traffic across borders using dedicated circuits such
as those provided by the Company. The alternative for the transport of this
traffic will be for these competing carriers to build their own transport
capacity or to use IPLCs. 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. In addition, IPLCs provided by the PTOs also have a
number of disadvantages, including high prices, lack of end-to-end quality
control, low quality due to diversity of network systems and equipment, limited
availability of bandwidth and long lead times for provisioning.
 
     The Company also expects this increase in competition to result in lower
prices and a substantial increase in the volume of traffic and range of
telecommunication services provided. As a result of the increased call volume
and growth in the offerings of value added services, participants in these
markets will require significant amounts of new cross-border telecommunications
transport capacity to provide their services. Service provider demand for
cross-border infrastructure is expected to exceed the demand due to switched
minute market growth. Customers will demand higher bandwidth and increased
quality levels required in a competitive environment. End users will have
requirements for vastly increased data traffic which has not been captured in
historical traffic statistics and requirements for increased bandwidth for new
applications.
 
   
HER POTENTIAL CUSTOMER BASE
    
 
   
     The Company is a carrier's carrier and will not offer services to end-user
customers. The Company's target customers include PTOs and New Entrants.
Currently an operator wishing to transport and terminate cross-border traffic in
Europe relies on the services of at least two (and in most cases more than two)
PTOs and is required to pay high prices without quality guarantees across the
circuit. HER intends to offer these target customers a better transport system
that can provide a higher level of transmission quality and service across
Europe at lower prices. The advantages that HER can offer its target customers
can be divided into two categories: advantages for facilities-based carriers,
such as PTOs and global consortia of telecommunications operators, and
advantages for non-facilities based carriers, which could include international
carriers, alternative carriers, value added networks, Internet backbone networks
and resellers.
    
 
                                       33
<PAGE>   40
 
   
     Facilities-based carriers.  The Company expects that carriers that already
own facilities will be interested in using the HER Network for a number of
reasons. PTOs are beginning to provide services in markets other than their home
market and are interested in procuring end-to-end connectivity. The HER Network
gives PTOs the ability to reconfigure or shift capacity among routes to avoid
over- and under-utilization of certain routes and to respond to changes in
end-user customer traffic. The HER Network can also provide additional
redundancy to a PTO or other facilities-based carrier's already existing
network. In addition, the Company believes that facilities-based carriers will
be attracted to the high quality of the HER Network.
    
 
   
     Non-facilities based carriers.  The Company expects that non-facilities
based carriers will be interested in using the HER Network because the Network
will offer high quality service at lower prices than currently offered by PTOs.
In addition, for Internet backbone networks, HER offers advanced technology and
is capable of handling large volumes of traffic. For all customers, HER virtual
network service offering is expected to be attractive because it allows for
flexibility in the provisioning of telecommunications transmission capacity.
Carriers from outside Europe will be able to connect to the HER Network for all
pan-European service needs. Additionally, the Company expects that New Entrants
who compete with facilities-based carriers will be reluctant to use a
competitor's facilities if alternative infrastructure such as the HER Network is
available, providing better quality service and pricing flexibility.
    
 
     Special pricing plans have been tailored to the unique needs of these
customer groups.

                                    BUSINESS
 
GENERAL
 
   
     HER's objective is to become the leading pan-European carriers' carrier by
providing cross-border centrally managed 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 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 ability to obtain the necessary financing, rights-of-way,
licenses and other regulatory approvals in a timely and cost-effective manner.
See "Risk Factors -- Risks Relating to HER Network Roll-out."
    
 
   
     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. HER began initial trials of the
Brussels-Amsterdam portion of the Network in the third quarter of 1996 and
commenced commercial service in November 1996. The Company expects the initial
five country network to be placed in operation in the second quarter of 1998 and
the 18,000 kilometer Network to be operational during the year 2000. 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.
    
 
   
     The Company expects to continue to roll-out full telecommunications
transport service on the initial five country network linking London, Rotterdam,
Amsterdam, Antwerp, Brussels, Paris, Dusseldorf and Frankfurt in the second
quarter of 1998. The initial five country network is expected to consist of
2,900 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 Network. Network coverage is
planned to be expanded to include Munich, Berlin, Geneva, Zurich, Stockholm,
Copenhagen and Milan in the third quarter of 1998. Additional extensions of the
Network to be completed in phases through the year 2000 will be built-out into
Southern and Central Europe. The HER Network is expected to have points of
presence in at least 32 cities in 15 European countries.
    
 
   
     HER has entered into agreements for the construction and/or lease of fiber
optic routes for the initial five country network, except for some of the routes
in Germany which are currently under negotiation. The Company has completed the
construction of two undersea cables connecting the United Kingdom to the
Netherlands and to Belgium, which were placed in commercial service in January
1998. In France, HER has reached agreement with an operator of motorways for the
use of approximately 600 kilometers of infrastructure in northern France, and
has agreements with other providers to complete the French segment of the
initial five country network. The Company expects to start commercial service
connecting Paris to Brussels, Amsterdam and London by January 1998. Contracts
have been concluded with respect to the portion of the Network connecting
Germany with each of France, the Netherlands and Switzerland.
    
 
   
     HER continues to negotiate rights-of-way and other infrastructure
arrangements in six other Western European countries representing the remainder
of the Western European portion of the rollout, which negotiations involve
railway and other infrastructure providers. The Company 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. See "Risk Factors -- Risks Relating to HER Network
Roll-out."
    
 
   
     HER was formed on July 6, 1993 by 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 purchased a 34.4% interest in HER in 1994 and has
increased its interest to 50% in 1995 and to approximately 79% in 1997.
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 other markets where
the carrier 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 intends to offer 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.
    
 
   
          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 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, the Company 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 the
     Company believes is unavailable in Western Europe today.
    
 
   
          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.
    
 
   
          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.
    
 
   
          Innovative Pricing.  Currently the price of E1 equivalent circuits on
     transborder European routes is artificially high and not necessarily
     related to the cost of such circuits. HER intends to offer competitive
     pricing. HER will also offer 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 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
not compete with
    
 
                                       36
<PAGE>   43
 
   
its carrier customers in end-user markets. HER believes that this independence
will make it an attractive service provider for Western European 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 over an integrated, managed pan-European network structure thus
providing a service for wholesale customers such as PTOs and New Entrants. HER's
service is not intended for business or residential end users. 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 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 telecommunications providers. Services are based on the principle of
adding greater value than currently available in the market while retaining
competitive prices.
    
 
   
     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 from PTOs. 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
    
 
                                       37
<PAGE>   44
 
   
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 is 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 fashion. 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. Due to the fact that HER is not required to
configure 'idle' bandwidth or 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, the Company
expects that its railway shareholders 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 the
Company to attractively and competitively price services in the face of
declining overall tariffs for telecommunication services. The Company'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 is expected to be from 1 to 3
years. The customer agrees to purchase, and the Company agrees to provide,
cross-border transmission services. In general, the customer agrees to pay
certain non-recurring charges 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 required to pay the Company a
cancellation charge equal to three months' service for each of the twelve months
remaining in the contract term. The Company guarantees transmission services to
a certain service level. If such levels are not met or the Company 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. HER will target seven major market segments or
customer groups which can be characterized as follows:
    
 
   
          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 very favorably to
     an alternative such as HER The Company believes that this segment will
     sustain the largest growth as competition emerges in Europe. The Company
     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.
    
 
   
          Existing PTOs.  This customer segment consists of the traditional
     European PTOs that generally participate in the standard bilateral
     agreements for cross-border connectivity. HER provides a vehicle for PTOs
     to compete in non-domestic markets both before and after January 1, 1998.
     Prior to January 1, 1998 when liberalization of the provision of switched
     telephony (reserved traffic) is scheduled to occur in the majority of
     Western European markets, a significant market opportunity for HER exists
     to provide cross-border transport services to PTOs for their non-reserved
     international traffic outside the standard ITU settlement process. 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
    
 
   
          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 infrastructure. Furthermore, HER believes that it is well
     positioned to provide cross-border connectivity between different domestic
     infrastructures of these alliances.
    
 
   
          International Carriers.  This customer segment consists of carriers
     whose primary business is to transport traffic between European and other
     international gateways. Such carriers include Teleglobe and GTS-Monaco
     Access. HER can provide these customers a pan-European distribution network
     to gather and deliver traffic to and from their own and other hubs.
    
 
   
          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.
    
 
          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.
 
   
          Value Added Networks ("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
    
 
                                       39
<PAGE>   46
 
     these needs cost-effectively, and to extend their services to new markets
     or customers without substantial capital investment.
 
     The Company 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.
 
CURRENT OPERATIONS
 
   
     HER currently operates a limited network connecting the cities of
Amsterdam, Brussels and recently London. HER is currently operating the network
on the Brussels-Amsterdam-London links with additional access points in Antwerp
and Rotterdam. HER began initial trials of a 244 kilometer portion of the
Network between Brussels and Amsterdam in the third quarter of 1996 and
commenced commercial service in November 1996. The Company'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. Currently 16 customers are under
contract for service on the HER Network, including PTOs, a global consortium of
PTOs, Internet service providers, an international carrier, a VAN and resellers.
HER provided capacity of approximately 110 E1 equivalent circuits as of October
31, 1997.
    
 
   
     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.
    
 
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. The Company
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 currently
uses a single vendor for the supply of transmission 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. The Company 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 the Company because they reduce the capital
expense burden
    
 
                                       40
<PAGE>   47
 
   
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. See "Risk Factors -- Risks Relating to HER
Network Roll-out."
    
 
   
     Network Capacity.  The Network will consist of SDH STM-16 links delivered
over fiber owned by HER and dark fiber leased from infrastructure providers.
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 the Network are Add-
Drop Multiplexors ("ADMs") and regulators and a variety of optical amplifiers
for boosting optical signals.
    
 
   
     Network Agreements.  The Company 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. The Company'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 the Company 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 an HER POP 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 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. 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
    
 
                                       41
<PAGE>   48
 
   
between HER and local access network suppliers can benefit both parties. Set
forth below is an illustration of the connection between the HER Network and
local access providers.

     The Dusseldorf-Amsterdam, Frankfurt-Dusseldorf and Paris-Frankfurt fiber
optic routes 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 or (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. See "Risk Factors -- Risks Related to HER Network Roll-Out."

     HER is deploying the Network along the rights-of-way of several
shareholders as well as the rights-of-way of a variety of alternative sources,
including motorways, waterways, pipelines and utilities. The rights-of-way of
Hermes-built portions of the Network will be provided pursuant to long-term
leases or other arrangements entered into with railroads, highway commissions,
pipeline owners, utilities or others. HER generally prefers to use the
infrastructure of its rail-based shareholders when such infrastructure is
available on a timely and commercially reasonable basis. In certain cases,
however, HER has not been able to reach agreement with such shareholders for the
provision of rights-of-way along their railways, which has resulted in
significant delays to the Network buildout. In all cases, 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,
the Company has gained access to infrastructure for its Network routes which, in
certain cases, the Company 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. The Company 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's business plan anticipates
substantial head-to-head competition as well as indirect competition.
    
 
     WorldCom, Inc. recently announced plans to construct a pan-European fiber
network, the first phase of which is expected to connect London, Amsterdam,
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.
 
   
     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 "Risk
Factors -- Competition."
    
 
                         LICENSES AND REGULATORY ISSUES
 
   
     A summary discussion of the regulatory framework in the countries of the
initial five country network and the next five countries into which HER expects
to develop a 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. The Company 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 five country network.
 
   
     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
and Germany and a license application for a trial concession has been filed in
Switzerland. A draft license has been received from the French regulatory
authorities which will be the basis for the final license. However, there can be
no assurance that such license will be granted. The
    
 
                                       43
<PAGE>   50
 
Company 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.
    
 
     On July 22, 1993, the Council of the 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.
 
   
     The Company 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 the Company'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 the Company
operates. There can be no assurance that future regulatory, judicial and
legislative changes will not have a material adverse effect on the Company, that
domestic or international regulators or third parties will not raise material
issues with regard to the Company's compliance or noncompliance with applicable
regulations or that regulatory activities will not have a material adverse
effect on the Company. See "Risk Factors -- Government Regulation." The
regulatory framework in certain jurisdictions in which the Company 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 telecommunica-
 
                                       44
<PAGE>   51
 
   
tions 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. The Company 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 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

     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. Full liberalization of competition, including
the provision of voice telephony, requires further legislation which is expected
to be introduced to the legislature in the near future. 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.
    
 
GERMANY
 
   
     Germany has approved legislation to implement the Full Competition
Directive and remove all remaining restrictions on competition from January
1998. The Company was granted a license by the German regulatory authorities on
July 18, 1997. The license permits the Company 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. The Company
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 has applied for
an authorization to operate its Network in specific regions of France.

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 has applied for a trial concession in order to roll out
its Networks and to provide its services in advance of the full liberalization
coming into effect on January 1998.
    
 
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 remain to be 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.

BOARD OF SUPERVISORY DIRECTORS
 
     The general affairs and business of the Company and the board which manages
the Company (the "Board of Managing Directors") (Directie) are supervised by a
board appointed by the general meeting of shareholders (the "Board of
Supervisory Directors") (Raad van Commissarissen).
 
     The Company's Articles of Association (the "Articles of Association")
provide for at least four and no more than ten supervisory directors who must be
natural persons ("Supervisory Directors") to serve on the Board of Supervisory
Directors. Under the law of the Netherlands, a Member of the Board of
Supervisory Directors of a Company cannot be a member of the Board of Managing
Directors of the same Company. The members of the Board of Supervisory Directors
are appointed by the general meeting of shareholders. The Board of Supervisory
Directors elects a chairman from among its members. See "Certain Relationships
and Related Transactions." Under the new Shareholders Agreement, resolutions of
the Board of Supervisory
 
                                       47
<PAGE>   54
 
Directors will require the approval of a majority of the Supervisory Directors
present. The quorum for a valid meeting is a majority of the members of the
Supervisory Board with a minimum of four members. The Board of Supervisory
Directors meets four times a year and also upon the request of its chairman or
the Board of Managing Directors. Pursuant to the Articles of Association,
Supervisory Directors may be suspended or dismissed by the general meeting of
shareholders. The remuneration or compensation of the Supervisory Directors is
determined by the general meeting of shareholders.
 
     While the Board of Managing Directors is the executive body of the Company
and is responsible for managing its affairs and representing the Company in its
dealings with third parties, the primary responsibility of the Board of
Supervisory Directors is to supervise the policies enacted by the Board of
Managing Directors and the general course of affairs of the Company. The Board
of Supervisory Directors advises the Board of Managing Directors. In the
fulfilment of their duties, members of the Board of Supervisory Directors are
required to act in the best interests of the Company.
 
BOARD OF MANAGING DIRECTORS
 
     The Board of Managing Directors, having one managing director (GTS-Hermes),
is charged with the management of the Company in accordance with the business
plan of the Company under the supervision of the Board of Supervisory Directors.
Jan Loeber acts on behalf of GTS-Hermes in this capacity. Under the Articles of
Association, the Board of Managing Directors must obtain the approval of the
Board of Supervisory Directors in order to take the following actions: (a) to
adopt and amend the business plan and the annual budget of the Company; (b) to
incur expenses in excess of the adopted or amended annual budget; (c) to incur
loans outside of the Company's ordinary business, except draw-downs of amounts
previously approved on the Company's account with a bank designated by the Board
of Supervisory Directors; (d) to lend sums which exceed the amounts previously
approved by the Board of Supervisory Directors outside the Company's ordinary
business; (e) to commit the Company to guarantee debts of third parties outside
the Company's ordinary business; (f) to extend the Company's business into a new
line of business and to discontinue the business of the Company; and (g) to
alienate a considerable part of the assets of the Company.
 
     The Articles of Association provide that the Board of Managing Directors
shall consist of one member. The member of the Board of Managing Directors is
appointed by the general meeting of shareholders. The general meeting of
shareholders may suspend or dismiss the member of the Management Board by a vote
of a majority of votes cast in a meeting in which at least four-fifths of the
issued capital is present or represented. If the office of the sole member of
the Board of Managing Directors is vacated or the sole member is prevented from
acting, the Board of Supervisory Directors is charged temporarily with
management of the Company and may appoint one or more of the directors of the
Board of Supervisory Directors to represent the Company. The compensation and
other terms and conditions of employment of the member of the Board of Managing
Directors is determined by the general meeting of shareholders.

 (1) The terms of the Named Executive Officer's employment are included in an
     agreement between the Named Executive Officer and GTS. Such Named Executive
     Officer is seconded to the Company for a fee.
 
 (2) Mr. Loeber received a cost of living allowance and paid home leave during
     fiscal year 1996. The Company provided Mr. Loeber with a tax equalization
     that compensates him for the higher taxes he pays because he resides in
     Belgium instead of the United States. Furthermore, the Company provided Mr.
     Loeber with a housing allowance equal to $31,836 per year (converted from
     Belgian Francs to U.S. Dollars at an exchange rate of BF32.0392=$1.00). In
     addition, the Company provides Mr. Loeber with the use of a company car.
 
 (3) Mr. Loeber has been granted a restricted stock award of 20,000 shares of
     GTS common stock which vests in equal thirds, beginning in January 2, 1997.
     GTS common stock is not registered or publicly traded and no market price
     is available for such stock. GTS completed a private placement of common
     stock in the third quarter of 1996 pursuant to which the common stock was
     valued at $20 per share. At December 31, 1996, GTS deemed the value of its
     common stock to be approximately $20 per share.
 
                                       51
<PAGE>   58
 
 (4) Stock options were granted under the GTS-Hermes, Inc. 1994 Stock Option
     Plan (the "GTS-Hermes Plan"). Each stock option is exercisable for one
     share of GTS-Hermes common stock, par value $0.01 per share at an exercise
     price equal to the fair market value of the stock on the date of grant as
     determined by a committee of the board of directors of GTS-Hermes. There is
     no ready market for the GTS-Hermes common stock. As of December 31, 1996,
     100 shares of GTS-Hermes common stock were outstanding. In the aggregate

GTS-HERMES 1994 STOCK OPTION PLAN
 
   
     The GTS-Hermes, Inc. 1994 Stock Option Plan (the "GTS-Hermes Plan") was
adopted by the board of directors of GTS-Hermes in 1994 to enable employees of
GTS-Hermes and its subsidiaries, including HER, and affiliates to participate in
ownership of GTS-Hermes and to attract and retain key employees of particular
merit. The GTS-Hermes Plan provides for the award of incentive stock options,
nonqualified stock options and stock appreciation rights. All employees of
GTS-Hermes and its subsidiaries, including HER, and affiliates are eligible to
participate in the GTS-Hermes Plan.
    
 
   
     The maximum number of shares authorized with respect to grants of awards
under the GTS-Hermes Plan in each calendar year is 6.5% of the shares of common
stock, par value $0.01 per share, of GTS-Hermes issued and outstanding, and the
aggregate number of shares of stock subject to the GTS-Hermes Plan is 13% of the
total shares of stock issued and outstanding. The GTS-Hermes Plan is
administered by a committee appointed by the board of directors of GTS-Hermes,
which has broad discretion to determine who shall receive awards under the HER
Plan and the characteristics of any award thereunder, including the price, term
and vesting of such award. However, stock appreciation rights may not be awarded
alone and may only be awarded in tandem with an option grant.
    
 
     The GTS-Hermes Plan provides that in the event of a change in control, as
defined under the GTS-Hermes Plan, any stock appreciation rights outstanding for
at least six months and any stock options awarded under the GTS-Hermes Plan not
previously exercisable and vested which have been held for at least six months
from the date of grant will become fully vested and exercisable at an adjusted
price to be determined according to the highest sales price per share paid in
any transaction reported or offer made at any time during the preceding 60 days
as determined by the committee.
 
     The board of directors of GTS-Hermes may amend, alter or discontinue the
GTS-Hermes Plan at any time, provided that the rights of participants are not
impaired.
 
   
     HER intends to establish a new stock option plan to replace the GTS-Hermes
Plan during the fourth quarter of 1997. The new plan, the Key Employee Stock
Option Plan of Hermes Europe Railtel B.V. (the "New Plan"), and the stock option
agreements that will be issued pursuant thereto have been drafted and are
pending final approval and execution. The options outstanding under the
GTS-Hermes Plan will be converted into options under the New Plan as soon as
practicable after such plan becomes effective. Upon establishment of the New
Plan, the GTS-Hermes Plan will be terminated.
    
 
PENSION PLAN
 
     In 1995, the Company established a defined benefit pension plan (the
"Pension Plan") that covers substantially all of its employees that are at least
twenty-five years of age and have at least one year of service. The benefits are
based on years of service and the employee's compensation at retirement. Messrs.
Magnus and Shearing participate in the Pension Plan. Each participant in the
Pension Plan will receive a lump sum at
 
                                       53
<PAGE>   60
 
retirement equal to 450% of final annual salary up to a specified ceiling which
changes every year (in 1996 the ceiling was BF1,352,000) plus 910% of the excess
multiplied by the years of service divided by 35. The maximum years of service
taken into account under the formula is 35. The normal retirement age is 60. The
Company has entered into an agreement with an insurance company for the
provision of a group insurance policy (the "Policy"). Under the Policy, the
insurance provider has undertaken a legal obligation to provide specified
benefits to participants in return for a fixed premium; accordingly, the Company
does not bear significant financial risk. Premium payments for the Policy are
partly paid by the employee based on specified terms that consider the
employee's annual salary, with the remaining premium paid by the Company.
Premiums are intended to provide not only for benefits attributed to service to
date but also for those expected to be earned in the future. (See Note 5 to the
Notes to Consolidated Financial Statements). Upon termination of employment
prior to retirement age, employer contributions cease and the participant may
decide to receive the cash surrender value of the policy, to continue paying
premiums or cease paying premiums but in either case maintaining the policy
which is paid out according to its terms.

The above pension benefits are based on the following formula:  (260% S1 + 910%
S2) X N/35
 
     S = annual salary
     S1 = S up to the "ceiling"
     S2 = S above the "ceiling"
     N = years of service up to a maximum of 35
 
For purposes of this calculation the "ceiling" is U.S. $42,200.
 
EMPLOYMENT AGREEMENTS
 
     All the Named Executive Officers have employment agreements with either the
Company (the "Company Employment Agreements") or GTS (the "GTS Employment
Agreements"). The Company reimburses GTS for payments made to Named Executive
Officers under contracts with GTS. The Employment Agreements generally are each
for a term of two to three years and include an automatic renewal provision
unless either party provides notice of termination on or prior to 90 days
thereof.
 
     Messrs. Magnus and Shearing have Company Employment Agreements. The
following is a summary of the material terms of such agreements. Mr. Magnus'
Company Employment Agreement was entered into by the parties on January 3, 1995

(2) The Company intends to establish a stock option plan pursuant to which key
    officers and employees will be granted options to purchase Ordinary Shares
    of the Company. The Company expects that the number of Ordinary Shares of

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
   
     HER was formed on July 6, 1993 by HIT Rail, a consortium of eleven Western
European railways. HIT Rail was incorporated in 1990 by these national railways
to carry out telecommunications engineering activities in order to construct and
exploit a data communications network for railway traffic. GTS-Hermes purchased
a 34.4% interest in HER in 1994, increased its interest to 50% in 1995 and
approximately 79% in 1997.
    
 
   
     GTS-Hermes is a wholly owned subsidiary of GTS. GTS is a U.S.-based
provider of a broad range of telecommunications services to businesses, other
telecommunications service providers and consumers in Russia and the
Commonwealth of Independent States, Western and Central Europe and Asia. GTS is
organized in the state of Delaware. At September 30, 1997, GTS had approximately
37.6 million shares of common stock outstanding and shareholders' equity of
$63.4 million.

<PAGE>   62
 
   
     HER has formed a wholly owned subsidiary, Hermes Europe Railtel N.V., a
company incorporated in Belgium in December 1996. The registered office of
Hermes Europe Railtel N.V. is 1560 Hoeilaart, Terhulpsesteenweg 6A, Belgium. The
authorized share capital is 2,500 shares (of which 2,499 shares are owned by the
Company) and the share capital is fully subscribed and amounts to BF 2,500,000.
Hermes Europe Railtel N.V. currently has no operations or revenue. Following the
Offering, HER intends to transfer all or substantially all of its assets and
liabilities (other than the Notes) to Hermes Europe Railtel N.V. After such
transfer, the Company will be a holding company with limited assets and will
operate its business through subsidiaries. As of the date hereof, the Company
has only one subsidiary and expects to form one or more subsidiaries in the
future.
    
 
   
HER RECAPITALIZATION
    
 
   
     HER has 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 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 79.08%, HIT Rail owns 12.63%, SNCB/NMBS owns 6.00%
and AB Swed Carrier owns 2.29% 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.
    
 
   
     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 as 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
the 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 HER Recapitalization 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 HER Recapitalization
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.
    
 
ARTICLES OF ASSOCIATION AND SHAREHOLDERS AGREEMENT
 
     Under the Articles of Association and the Shareholders Agreement between
GTS-Hermes and HIT Rail, both GTS-Hermes and HIT Rail 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 each of them.

     The Shareholders Agreement provides that the Company or its designated
vendor will provide fiber capacity in its Network for use by the shareholders of
the Company 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 the Company, to obtain rights of way from
individual HIT Rail shareholders and to cooperate in obtaining such licenses as
may advance the business of the Company, (ii) use its best efforts to ensure
that the HIT Rail shareholders cooperate in obtaining such license in accordance
with the business plan of the Company and as may be necessary or advisable in
furtherance of the Company's business, (iii) will not, so long as both HIT Rail
and GTS-Hermes are shareholders of the Company and for one year after HIT Rail
ceases to be a shareholder, agree with any entity other than GTS-Hermes and the
Company to assist or cooperate in the development of any pan-European
telecommunications operator and (iv) use its best efforts to obtain on the
Company'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.

complete and is qualified in its entirety by reference to the Shareholders
Agreement.

                       DESCRIPTION OF THE EXCHANGE NOTES
 
     The Outstanding Notes were issued under an Indenture (the "Indenture")
dated as of August 19, 1997 among the Company, GTS (with respect only to the
provisions described under "-- Covenant of GTS") and The Bank of New York, as
trustee (the "Trustee"). The Exchange Notes will be issued under the Indenture,
which will be qualified under the United States Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"), upon the effectiveness of the Registration
Statement of which this Prospectus is a part. The form and terms of the Exchange
Notes are the same in all material respects as the form and terms of the
Outstanding Notes, except that the Exchange Notes will have been registered
under the Securities Act and, therefore, will not bear legends restricting
transfer thereof. Upon the consummation of the Exchange Offer, holders of
Outstanding Notes will not be entitled to registration rights under, or the
contingent increase in interest rate provided pursuant to, the Registration
Rights Agreement. The Exchange Notes will evidence the same debt as the
Outstanding Notes and will be treated as a single class under the Indenture with
any Outstanding Notes that remain outstanding. The Outstanding Notes and
Exchange Notes are herein collectively referred to as the "Notes."
 
   
     The following summary of certain provisions of the Indenture, the Escrow
Agreement and the Registration Rights Agreement does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, the Trust
Indenture Act, and to all of the provisions of the Indenture, the Escrow
Agreement and the Registration Rights Agreement, including the definitions of
certain terms therein and those terms made a part of the Indenture by reference
to the Trust Indenture Act. Copies of the Indenture, the Escrow Agreement and
the Registration Rights Agreement have been filed with the Commission as an
Exhibit to the Registration Statement of which this Prospectus is part. The
definitions of certain terms used in the following summary are set forth under
"-- Certain Definitions." References in this "Description of the Exchange Notes"
section to "the Company" mean only HER and not any Subsidiary.
    
 
GENERAL
 
     The Notes will be issued only in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. The Company will
initially appoint the Trustee to serve as registrar and principal paying agent
under the Indenture at its offices at 101 Barclay Street, New York, New York
10286. The registrar, paying agents, and transfer agents (the "Registrar,"
"Paying Agents" and "Transfer Agents," respectively) are appointed in accordance
with the Indenture and initially are as set forth on the inside back cover page
hereof. No service charge will be made for any registration of transfer or
exchange of the Notes, except for any tax or other governmental charge that may
be imposed in connection therewith.
 
RANKING
 
     The Notes will be general unsecured obligations of the Company and will
rank senior in right of payment to all future Indebtedness of the Company that
is, by its terms or by the terms of the agreement or instrument governing such
Indebtedness, expressly subordinated in right of payment to the Notes and pari
passu in right of payment with all existing and future unsecured liabilities of
the Company that are not so subordinated.
 
   
     During and following the Exchange Offer, the Company intends to transfer
all or substantially all of its assets and liabilities (other than the Notes) to
Subsidiaries. After such transfer, the Company will be a holding company with
limited assets and will operate its business through Subsidiaries. Any right of
the Company and its creditors, including holders of the Notes, to participate in
the assets of any of the Company's Subsidiaries upon any liquidation or
administration of any such Subsidiary will be subject to the prior claims of the
creditors of such Subsidiary. The claims of creditors of the Company, including
holders of the Notes, will be effectively subordinated to all existing and
future third-party indebtedness and liabilities, including trade payables, of
the Company's Subsidiaries. At September 30, 1997, the Company's Subsidiaries
had total liabilities of $19.0 million reflected on the Company's balance sheet.
The Company and its Subsidiaries may incur other debt in the future, including
secured debt.
    
 
                                       58

     The Notes will not be entitled to any security, except as described under
"-- Escrow Account" and will not be entitled to the benefit of any guarantees,
except under the circumstances described under "-- Certain
Covenants -- Limitation on Issuances of Guarantees by Restricted Subsidiaries."
 
MATURITY, INTEREST AND PRINCIPAL OF THE NOTES
 
     The Notes will be limited to $265.0 million aggregate principal amount and
will mature on August 15, 2007. The Notes will be payable at maturity at par,
plus accrued and unpaid interest, if any. Cash interest on the Notes will accrue
at the rate per annum set forth on the cover page of this Prospectus and will be
payable semi-annually in arrears on each February 15 and August 15, commencing
February 15, 1998, to the holders of record of Notes (the "Holders") at the
close of business on February 1 and August 1, respectively, immediately
preceding such interest payment date. Cash interest will accrue from the most
recent interest payment date to which interest has been paid or, if no interest
has been paid, from the Issue Date. Holders of the Exchange Notes will receive
interest on February 15, 1998, from the date of initial issuance of the Exchange
Notes, plus an amount equal to the accrued interest on the Outstanding Notes
from the later of (i) the most recent date to which interest has been paid
thereon and (ii) the date of issuance of the Outstanding Notes, to the date of
exchange thereof. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.
 
     The Luxembourg Stock Exchange will be informed of each change in the
interest rate of the Notes on the date of such change. The Company will cause a
copy of such notice to be published in a daily newspaper with general
circulation in Luxembourg (which is expected to be the Luxemburger Wort).
 
     Principal of, and interest on, the Notes will be payable, and the transfer
of Notes will be registrable, at the office of the Trustee, and at the offices
of the Paying Agents and Transfer Agents, respectively. Payments of such
principal and premium, if any, will be made against surrender of Certificated
Notes at the corporate trust office of the Paying Agent in New York City or,
subject to any applicable laws and regulations, at the offices of the Paying
Agent in Luxembourg by United States dollar check drawn on, or wire transfer to
a United States dollar account maintained by the holder with, a bank located in
New York City. Payments of any installment of interest on Certificated Notes
will be made by a United States dollar check drawn on a bank in New York City
mailed to the holder at such holder's registered address or (if arrangements
satisfactory to the Company and the Paying Agents are made) by wire transfer to
a dollar account maintained by the holder with a bank in New York City. For so
long as the Notes are listed on the Luxembourg Stock Exchange and the rules of
such stock exchange so require, the Company will maintain a Paying Agent and a
Transfer Agent in Luxembourg.
 
     If a payment date is not a Business Day at a place of payment, payment may
be made at that place on the next succeeding Business Day and no interest shall
accrue for the intervening period.
 
     The Company may at any time deliver Notes to the Trustee for cancellation.
Subject to the terms of the Indenture, the Company may not issue new Notes to
replace Notes that it has paid or delivered to the Trustee for cancellation.
 
ADDITIONAL AMOUNTS
 
     All payments made by the Company under or with respect to the Notes will be
made free and clear of and without withholding or deduction for or on account of
any present or future Taxes imposed or levied by or on behalf of any Taxing
Authority within the Netherlands, or within any other 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 the
Netherlands, or within any other jurisdiction in which the Company is organized
or engaged in business for tax purposes, from any payment made under or with
respect to the Notes, the Company will pay such additional amounts ("Additional
Amounts") as may be necessary so that the net amount received by each holder of
Notes (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
 
                                       59
<PAGE>   66
 
ultimately entitled to obtain an interest in, such Notes) and the Netherlands or
other jurisdiction in which the Company is organized or engaged in business for
tax purposes other than the mere holding of the Notes; (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 Notes (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 Notes had
been the holder of the Notes and would not be entitled to the payment of
Additional Amounts. 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 Notes.
 
     Whenever in the Indenture or in this "Description of the Notes" there is
mentioned, in any context, the payment of amounts based upon the principal
amount of the Notes or of principal, interest or of any other amount payable
under or with respect to any of the Notes, such mention shall be deemed to
include mention of the payment of Additional Amounts to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof.
 
ESCROW ACCOUNT
 
     Pursuant to the Indenture, the Company has purchased, pledged and
transferred to the Trustee for the benefit of the holders of the Notes the
Pledged Securities in such amount as will be sufficient upon scheduled interest
and principal payments of such securities to provide for the payment in full of
the first four scheduled interest payments on the Notes (excluding any
Additional Amounts or Additional Interest). The Company has used approximately
$56.5 million of the net proceeds of the Offering to acquire the Pledged
Securities. The Pledged Securities have been pledged to the Trustee for the
benefit of the Holders of the Notes and deposited into an escrow account (the
"Escrow Account") held by the Escrow Agent for the benefit of the Trustee and
the Holders in accordance with an escrow agreement entered into among the
Company, The Bank of New York, as escrow agent (the "Escrow Agent") and the
Trustee (the "Escrow Agreement"). The Escrow Agreement provides, among other
things, that funds may be disbursed from the Escrow Account for interest
payments on the Notes. The Escrow Agent has been instructed to cause any
uninvested funds in the Escrow Account to be invested, pending disbursement, in
Cash Equivalents. Interest earned on the Pledged Securities and any Cash
Equivalents will be added to the Escrow Account.
 
     Under the Escrow Agreement, the Company granted to the Trustee, for the
benefit of the Holders, a first priority and exclusive security interest in all
funds and securities in the Escrow Account and the proceeds thereof (the "Escrow
Collateral"). The Escrow Agreement provides that the Trustee may foreclose on
the Escrow Collateral upon acceleration of the maturity of the Notes. Under the
terms of the Indenture, the proceeds of the Escrow Collateral will be applied,
first, to amounts owing to the Trustee in respect of fees and expenses of the
Trustee, and second, to the Obligations of the Company to the Holders under the
Notes and the Indenture. The ability of Holders to realize upon the Escrow
Collateral may be subject to certain bankruptcy law limitations in the event of
the bankruptcy of the Company.
 
     Upon payment in full of the first four scheduled interest payments
(including any Additional Amounts or Additional Interest), if no Default has
occurred and is continuing, the Escrow Collateral will be released to the
Company.
 
OPTIONAL REDEMPTION
 
     The Notes 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 August 15, 2002, upon not
less than 30 nor more than 60 days' prior notice mailed by first class mail to
each Holder's registered address, at the redemption prices (expressed as a
percentage of principal
 
                                       60

  REDEMPTION UPON PUBLIC EQUITY OFFERING OR STRATEGIC EQUITY INVESTMENT
 
     At any time or from time to time prior to August 15, 2000, upon not less
than 30 nor more than 60 days' prior notice mailed by first class mail to each
Holder's registered address, the Company may redeem Notes at a redemption price
equal to 111.5% of the principal amount of the Notes so redeemed, plus accrued
and unpaid interest thereon, if any, to the date of redemption with the net cash
proceeds of one or more Public Equity Offerings or Strategic Equity Investments
resulting in aggregate gross cash proceeds to the Company of at least $75.0
million; provided, however, that at least two-thirds of the principal amount of
Notes originally issued would remain outstanding immediately after giving effect
to any such redemption (excluding any Notes owned by the Company or any of its
Affiliates) (it being understood that the foregoing shall not apply to proceeds
received in connection with the GTS Contribution). Notice of any such redemption
must be given within 60 days after the date of a 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.
 
  REDEMPTION FOR CHANGES IN WITHHOLDING TAXES
 
     The Company may, at any time, at its option, redeem all (but not less than
all) of the Notes then outstanding at 100% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of redemption, if the Company
has become or would become obligated to pay, on the next date on which any
amount would be payable with respect to the Notes, any Additional Amounts as a
result of change in law (including any regulations promulgated thereunder) or in
the interpretation or administration thereof, if such change is announced and
becomes effective on or after the Issue Date.
 
SELECTION AND NOTICE OF REDEMPTION
 
     In the event that less than all of the Notes are to be redeemed at any time
pursuant to an optional redemption, selection of such Notes for redemption will
be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not then listed on a national securities exchange, on a pro rata
basis, by lot or by such method as the Trustee shall deem fair and appropriate;
provided, however, that no Notes of a principal amount of $1,000 or less shall
be redeemed in part; provided, further, however, that if a partial redemption is
made pursuant to the provisions described in the second paragraph under
"-- Optional Redemption," selection of the Notes 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
Trust Company), unless such method is otherwise prohibited. Notice of redemption
shall be mailed by first-class mail at least 30 but not more than 60 days before
the date of redemption to each Holder of Notes to be redeemed at its registered
address. The Company will cause a copy of such notice to be published in a daily
newspaper with general circulation in Luxembourg (which is expected to be the
Luxembourger Wort). If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note 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 Note. On and after the date of redemption, interest
will cease to accrue on Notes or portions thereof called for redemption as long
as the Company has deposited with the Paying Agents in New York and Luxembourg
for the Notes funds in satisfaction of the redemption price pursuant to the
Indenture.

<PAGE>   68
 
CHANGE OF CONTROL
 
     Following the occurrence of a Change of Control (the date of such
occurrence being the "Change of Control Date"), the Company shall notify the
Holders of such occurrence in the manner prescribed by the Indenture and shall,
within 30 days after the Change of Control Date, make an Offer to Purchase all
Notes then outstanding 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. The Company will cause a copy of such notice to be
published in a daily newspaper with general circulation in Luxembourg (which is
expected to be the Luxembourger Wort). 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 the Indenture
applicable to an Offer to Purchase made by the Company and purchases all Notes
validly tendered and not withdrawn under such Offer to Purchase.
 
     If an Offer to Purchase is made, there can be no assurance that the Company
will have available funds sufficient to pay for all of the Notes that might be
tendered by Holders seeking to accept the Offer to Purchase. If the Company
fails to purchase all of the Notes tendered for purchase upon the occurrence of
a Change of Control, such failure will constitute an Event of Default. See
"-- Events of Default" and "-- Risk Factors -- Change of Control."
 
     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 Notes are listed, and any
violation of the provisions of the Indenture relating to such Offer to Purchase
occurring as a result of such compliance shall not be deemed a Default.

        Interests after the Issue Date (other than any issuance and sale of
        Qualified Equity Interests financed, directly or indirectly, using funds
        (I) borrowed from the Company or any Subsidiary until and to the extent
        such borrowing is repaid or (II) contributed, extended, guaranteed or
        advanced by the Company or any Subsidiary (including, without
        limitation, in respect of any employee stock ownership or benefit
        plan)), plus
 
             (3) the aggregate amount by which Indebtedness (other than any
        Subordinated Indebtedness) of the Company or any Restricted Subsidiary
        is reduced on the Company's balance sheet upon the conversion or
        exchange (other than by a Subsidiary of the Company) subsequent to the
        Issue Date into Qualified Equity Interests (less the amount of any cash,
        or the fair value of property, distributed by the Company or any
        Restricted Subsidiary upon such conversion or exchange), plus
 
             (4) in the case of the disposition or repayment of any Investment
        that was treated as a Restricted Payment made after the Issue Date, an
        amount (to the extent not included in the computation of Cumulative
        Operating Cash Flow) equal to the lesser of: (x) the return of capital
        with respect to such Investment and (y) the amount of such Investment
        that was treated as a Restricted Payment, in either case, less the cost
        of the disposition of such Investment and net of taxes, plus
 
             (5) so long as the Designation thereof was treated as a Restricted
        Payment made after the Issue Date, with respect to any Unrestricted
        Subsidiary that has been redesignated as a Restricted Subsidiary after
        the Issue Date in accordance with "-- Designation of Unrestricted
        Subsidiaries," the Company's proportionate interest in an amount equal
        to the excess of (x) the total assets of such Subsidiary, valued on an
        aggregate basis at the lesser of book value and Fair Market Value, over
        (y) the total liabilities of such Subsidiary, determined in accordance
        with GAAP (and provided that such amount shall not in any case exceed
        the Designation Amount with respect to such Restricted Subsidiary upon
        its Designation), minus
 
             (6) with respect to each Subsidiary of the Company which has been
        designated as an Unrestricted Subsidiary after the Issue Date in
        accordance with "-- Designation of Unrestricted Subsidiaries," the
        greater of (x) $0 and (y) the Designation Amount thereof (measured as of
        the Date of Designation).
 
     Notwithstanding the foregoing, the GTS Contribution shall not be taken into
account in calculating the Basket.
 
     The foregoing provisions will not prevent (i) the payment of any dividend
or distribution on, or redemption of, Equity Interests within 60 days after the
date of declaration of such dividend or distribution or the giving of formal
notice of such redemption, if at the date of such declaration or giving of
formal notice such payment or redemption would comply with the provisions of the
Indenture; (ii) the purchase, redemption, retirement or other acquisition of any
Equity Interests of the Company in exchange for, or out of the net cash proceeds
of the substantially concurrent (A) common equity capital contribution to the
Company from any Person (other than a Subsidiary) or (B) issue and sale (other
than to a Subsidiary) of, Qualified Equity Interests; (iii) any Investment to
the extent that the consideration therefor consists of the net proceeds of the
substantially concurrent issue and sale (other than to a Subsidiary) of
Qualified Equity Interests; (iv) the purchase, redemption, retirement,
defeasance or other acquisition of Subordinated Indebtedness made in exchange
for, or out of the net cash proceeds of, a substantially concurrent issue and
sale (other than to a Subsidiary) of, (x) Qualified Equity Interests or (y)
other Subordinated Indebtedness having no stated maturity for the payment of
principal thereof prior to the Maturity Date; or (v) any Investment in any
Person principally engaged in a Telecommunications Business; provided, however,
that Investments pursuant to this clause (v) shall not exceed $25.0 million in
the aggregate at any time outstanding; provided, further, however,
 
                                       63
<PAGE>   70
 
that in the case of each of clauses (ii), (iii), (iv) and (v), no Default shall
have occurred and be continuing or would arise therefrom.
 
     Limitation on Incurrence of Indebtedness.  (a) The Company shall not, and
shall not cause or permit any Restricted Subsidiary to, directly or indirectly,
Incur any Indebtedness; provided, however, that the Company may Incur
Indebtedness if, at the time of such Incurrence, the Debt to Annualized
Operating Cash Flow Ratio would be less than or equal to 6.0 to 1.0.
 
          (b) The foregoing limitations of paragraph (a) of this covenant will
     not apply to any of the following, each of which shall be given independent
     effect:
 
             (i) the Notes and the Exchange Notes, and Permitted Refinancings
        thereof;
 
             (ii) Indebtedness of the Company or any Restricted Subsidiary to
        the extent outstanding on the date of the Indenture, and Permitted
        Refinancings thereof;
 
             (iii) Indebtedness of the Company or Qualified Subsidiary
        Indebtedness, 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
        the Company or a Restricted Subsidiary after the Issue Date, and
        Permitted Refinancings thereof;
 
             (iv) (1) Indebtedness of the Company or Qualified Subsidiary
        Indebtedness, in each case, to the extent that the proceeds of or credit
        support provided by such Indebtedness is used to finance a
        Telecommunications Acquisition, or working capital for, or to finance
        the construction of, the business or network acquired and (2) Acquired
        Indebtedness, and, in each case, Permitted Refinancings thereof, but in
        each case only to the extent that (x) the aggregate amount of
        Indebtedness outstanding of the Company and the Restricted Subsidiaries
        after giving effect to the Incurrence of such Indebtedness and the
        application of the proceeds therefrom does not exceed the product of 2.0
        and the Share Capital of the Company at the date of Incurrence of such
        Indebtedness or (y) the aggregate amount of such Indebtedness or
        Acquired Indebtedness, together with all Indebtedness of the Person, if
        any, that is to become a Restricted Subsidiary or be merged or
        consolidated with or into the Company or any Restricted Subsidiary in
        the contemplated transaction outstanding at the time of such transaction
        (whether or not Incurred in connection with, or in contemplation of,
        such transaction), does not exceed the net sum of the plant, property
        and equipment set forth on the Latest Balance Sheet of such Person;
 
             (v) (1) Indebtedness of any Restricted Subsidiary owed to and held
        by the Company or any Restricted Subsidiary and (2) Indebtedness of the
        Company owed to and held by any Restricted Subsidiary which is unsecured
        and subordinated in right of payment to the payment and performance of
        the Company's obligations under the Notes; provided, however, that an
        Incurrence of Indebtedness that is not permitted by this clause (v)
        shall be deemed to have occurred upon (x) any sale or other disposition
        of any Indebtedness of the Company or any Restricted Subsidiary referred
        to in this clause (v) to any Person other than the Company or any
        Restricted Subsidiary or (y) any Restricted Subsidiary that holds
        Indebtedness of the Company or another Restricted Subsidiary ceasing to
        be a Restricted Subsidiary;
 
             (vi) Interest Rate Protection Obligations of the Company or any
        Restricted Subsidiary relating to Indebtedness of the Company or such
        Restricted Subsidiary, as the case may be (which Indebtedness (x) bears
        interest at fluctuating interest rates and (y) 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 Indebtedness to which such Interest
        Rate Protection Obligations relate;
 
             (vii) Indebtedness of the Company or any Restricted Subsidiary
        under Currency Agreements to the extent relating to (x) Indebtedness of
        the Company or such Restricted Subsidiary, as the case may be, and/or
        (y) obligations to purchase assets, properties or services incurred in
        the ordinary course of business of the Company or such Restricted
        Subsidiary, as the case may be; provided, however, that such Currency
        Agreements do not increase the Indebtedness or other obligations of
 
                                       64
<PAGE>   71
 
        the Company and the Restricted Subsidiaries outstanding other than as a
        result of fluctuations in foreign currency exchange rates or by reason
        of fees, indemnities or compensation payable thereunder;
 
             (viii) Indebtedness of the Company and/or any Restricted Subsidiary
        in respect of performance bonds of the Company or any Restricted
        Subsidiary or surety bonds provided by the Company or any Restricted
        Subsidiary incurred in the ordinary course of business and on ordinary
        business terms in connection with the construction or operation of a
        Telecommunications Business; and
 
             (ix) in addition to the items referred to in clauses (i) through
        (viii) above, Indebtedness of the Company or Qualified Subsidiary
        Indebtedness in an aggregate amount not to exceed $15.0 million at any
        time outstanding.
 
          (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 "-- Limitation on Issuances of Guarantees by Restricted
     Subsidiaries."
 
          (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.
 
     Limitation on Restrictions Affecting Restricted Subsidiaries.  The Company
shall not, and shall not cause or permit any Restricted Subsidiary 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 Subsidiary to
(x) pay dividends or make any other distributions to the Company or any other
Restricted Subsidiary 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 Subsidiary, (y) make
loans or advances to, or guarantee any Indebtedness or other obligations of, the
Company or any other Restricted Subsidiary or (z) transfer any of its properties
or assets to the Company or any other Restricted Subsidiary.
 
     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 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 Capital Stock or assets of a Restricted Subsidiary;
provided, however, that (x) such encumbrance or restriction is applicable only
to such Restricted Subsidiary or assets and (y) such sale or disposition is made
in accordance with "-- Limitation on Asset Sales"; (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 Subsidiary; (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 a Restricted Subsidiary (to the extent that such Liens were
otherwise incurred in accordance with "-- Limitation on Liens") 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 Subsidiary 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; or (h) 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 in
existence at the Issue Date.

     Designation of Unrestricted Subsidiaries.  (a) The Company may designate
any Subsidiary of the Company as an "Unrestricted Subsidiary" under the
Indenture (a "Designation") only if:
 
          (i) no Default shall have occurred and be continuing at the time of or
     after giving effect to such Designation;
 
          (ii) at the time of and after giving effect to such Designation, the
     Company could Incur $1.00 of additional Indebtedness under the first
     paragraph of "-- Limitation on Incurrence of Indebtedness"; and
 
          (iii) the Company would be permitted to make an Investment (other than
     a Permitted Investment) at the time of Designation (assuming the
     effectiveness of such Designation) pursuant to the first paragraph of
     "-- Limitation on Restricted Payments" in an amount (the "Designation
     Amount") equal to the Fair Market Value of the Company's proportionate
     interest in the net worth of such Subsidiary on such date calculated in
     accordance with GAAP.
 
     All Subsidiaries of Unrestricted Subsidiaries shall be Unrestricted
Subsidiaries.
 
     The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, directly or indirectly, at any time (x) provide credit support
for, subject any of its properties or assets (other than the Equity Interests of
any Unrestricted Subsidiary) to the satisfaction of, or guarantee, any
Indebtedness of any Unrestricted Subsidiary (including any undertaking,
agreement or instrument evidencing such Indebtedness), (y) be liable for any
Indebtedness of any Unrestricted Subsidiary or (z) be liable for any
Indebtedness 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 Subsidiary.
 
     (b) The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") only if:
 
          (i) no 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 Subsidiary
     outstanding immediately following such Revocation would, if Incurred at
     such time, have been permitted to be Incurred for all purposes of the
     Indenture; and
 
          (iii) any transaction (or series of related transactions) between such
     Subsidiary and any of its Affiliates that occurred while such Subsidiary
     was an Unrestricted Subsidiary would be permitted by "-- Limitation on
     Transactions with Affiliates" as if such transaction (or series of related
     transactions) had occurred at the time of such Revocation (after giving
     effect to any modification to such transaction (or series of related
     transactions) effective at such time).
 
     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.
 
     Limitation on Liens.  The Company shall not, and shall not cause or permit
any Restricted Subsidiary to, directly or indirectly, Incur 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
Notes, effective provision is made to secure the Notes 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 Notes, effective provision is made to secure the Notes 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.
 
     Limitation on Asset Sales.  The Company shall not, and shall not cause or
permit any Restricted Subsidiary to, directly or indirectly, make any Asset
Sale, unless (x) the Company or such Restricted Subsidiary, 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
 
                                       66
<PAGE>   73
 
(i) cash or Cash Equivalents, (ii) Replacement Assets, (iii) publicly traded
Equity Interests of a Person who is engaged primarily in a Telecommunications
Business; provided, however, that the Company or such Restricted Subsidiary
shall sell (a "Monetization Sale"), for cash or Cash Equivalents, such Equity
Interests to a third Person (other than to the Company or a Subsidiary thereof)
at a price not less than the Fair Market Value thereof within 365 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 Subsidiary that is
actually assumed by the transferee in such Asset Sale and from which the Company
and the Restricted Subsidiaries are fully released shall be deemed to be cash
for purposes of determining the percentage of cash consideration received by the
Company or such Restricted Subsidiary and (y) notes or other similar obligations
received by the Company or any Restricted Subsidiary from such transferee that
are immediately converted, sold or exchanged (or are converted, sold or
exchanged within 365 days of the related Asset Sale) by the Company or any
Restricted Subsidiary 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 Subsidiary. Any Net Cash Proceeds from any Asset Sale
or any Monetization Sale that are not invested in Replacement Assets or used to
repay and permanently reduce the commitments under Indebtedness of any
Restricted Subsidiary within 365 days of the consummation of such Asset Sale or
Monetization Sale 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 Notes as can be purchased with the
Note Portion of Excess Proceeds at a price in cash equal to 100% of the
principal amount thereof, plus accrued and unpaid interest, if any, to any
purchase date. To the extent that the aggregate amount of principal and accrued
interest of Notes 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 amount of principal and accrued
interest of Notes validly tendered and not withdrawn by Holders thereof exceeds
the amount of Notes that can be purchased with the Note Portion of Excess
Proceeds, Notes to be purchased will be selected pro rata based on the aggregate
principal amount of Notes tendered by each Holder. Upon completion of an Offer
to Purchase, the amount of Excess Proceeds with respect to the applicable Asset
Sale or Monetization Sale shall be reset to zero.
 
     In the event that any other Indebtedness of the Company that ranks pari
passu with the Notes (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
Notes is not less than the Note 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, "Note 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 Notes tendered
pursuant to the Offer to Purchase related to such Excess Proceeds (the "Note
Amount") and the denominator of which is the sum of the Note 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.
 
     In the event that the Company makes an Offer to Purchase the Notes, 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 the 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.
 
                                       67
<PAGE>   74
 
     Limitation on Transactions with Affiliates.  The Company shall not, and
shall not cause or permit any Restricted Subsidiary 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 or any officer, director or employee of the
Company or any Restricted Subsidiary (each, an "Affiliate Transaction"), unless
such Affiliate Transaction is on terms that are no less favorable to the Company
or such Restricted Subsidiary, 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 $12.5 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 Subsidiary, 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 Subsidiaries or between or among Restricted Subsidiaries; (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 Subsidiary 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 Subsidiary for travel, entertainment,
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 Subsidiary, on the one hand, and any
Affiliate of the Company 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; (vi) any payment pursuant to any tax sharing agreement
between the Company and any other Person with which the Company files a
consolidated tax return or with which the Company is part of a consolidated
group for tax purposes; provided that such payment is not greater than that
which the Company would be required to pay as a stand-alone taxpayer; (vii) the
pledge of Equity Interests of Unrestricted Subsidiaries to support the
Indebtedness thereof; and (viii) payment of dividends in respect of Equity
Interests of the Company or any Restricted Subsidiary permitted under the
covenant described under "-- Limitation on Restricted Payments."
 
     Limitation on Issuances of Guarantees by Restricted Subsidiaries.  The
Company shall not cause or permit any Restricted Subsidiary, directly or
indirectly, to guarantee any Indebtedness of the Company ("Guaranteed
Indebtedness"), unless (i) such Restricted Subsidiary simultaneously executes
and delivers a supplemental indenture to the Indenture pursuant to which such
Restricted Subsidiary guarantees (a "Subsidiary Guarantee") all of the Company's
obligations under the Notes and the Indenture and (ii) such Restricted
Subsidiary 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 Subsidiary as a
result of any payment by such Restricted Subsidiary under its Subsidiary
Guarantee. If the Guaranteed Indebtedness is (A) pari passu with the Notes, then
the guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated to the Notes, then
the guarantee of such Guaranteed Indebtedness shall be subordinated to the
Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness is
subordinated to the Notes.
 
     Any Subsidiary Guarantee by a Restricted Subsidiary 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
Subsidiary in, or all or substantially all the assets of, such Restricted
Subsidiary (which sale, exchange or transfer is made in accordance with the
Indenture) or (ii) the release or discharge of the guarantee which
 
                                       68
<PAGE>   75
 
resulted in the creation of such Subsidiary Guarantee, except a discharge or
release by or as a result of payment under such guarantee.
 
     Limitation on the Issuance and Sale of Capital Stock of Restricted
Subsidiaries.  The Company shall not sell, and shall not cause or permit any
Restricted Subsidiary, directly or indirectly, to issue or sell, any Equity
Interests of a Restricted Subsidiary, except (i) to the Company or a Wholly
Owned Restricted Subsidiary; (ii) if, immediately after giving effect to such

COVENANT OF GTS

constitutes "Senior Indebtedness" under that certain indenture noted as of July
14, 1997 between GTS and The Bank of New York relating to GTS' Senior
Subordinated Convertible Bonds due 2000, and is incurred pursuant to clause (c)
of the second paragraph of the "Limitation on Indebtedness" covenant.
 
EVENTS OF DEFAULT
 
     The occurrence of any of the following will be defined as an "Event of
Default" under the Indenture: (a) failure to pay principal of any Note when due;
(b) failure to pay any interest on any Note when due, continued for 30 days or
more; (c) failure to pay on the Purchase Date the Purchase Price for any Note
validly tendered pursuant to any Offer to Purchase; (d) failure to perform or

Covenants -- Merger, Sale of Assets, etc."; (e) failure to perform any other
covenant, warranty or agreement of the Company under the Indenture or the Escrow
Agreement or in the Notes continued for 30 days or more after written notice to
the Company by the Trustee or Holders of at least 25% in aggregate principal
amount of the outstanding Notes; (f) there shall be, with respect to any issue
or issues of Indebtedness of the Company or any Restricted Subsidiary 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
proceeding 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 (but not any interim) 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 against the Company or any
Restricted Subsidiary in an amount of $10.0 million or more which remains
undischarged or unstayed for a period of 60 consecutive days; (h) certain events

Significant Restricted Subsidiary; or (i) 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 Escrow Collateral
shall become subject to any Lien other than the Lien under the Escrow Agreement.
 
     If an Event of Default with respect to the Notes (other than an Event of
Default with respect to the Company described in clause (h) of the preceding
paragraph) occurs and is continuing, the Trustee or the Holders of at least 25%
in aggregate principal amount of the outstanding Notes by notice in writing to
the Company may declare the unpaid principal of and accrued interest to the date
of acceleration on all the outstanding Notes to be due and payable immediately
and, upon any such declaration, such principal amount and accrued interest,
notwithstanding anything contained in the Indenture or the Notes to the
contrary, will become immediately due and payable; provided, however, that after
such acceleration, but before a judgment or decree based on acceleration, the
Holders of a majority in aggregate principal amount of outstanding Notes may,
under certain circumstances, rescind and annul such acceleration if all Events
of Default, other than the nonpayment of accelerated principal, have been cured
or waived as provided in the Indenture. If an Event or Default specified in
clause (h) of the preceding paragraph with respect to the Company occurs under
the
 
                                       70
<PAGE>   77
 
Indenture, the Notes will ipso facto become immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.
 
     The Indenture provides that the Trustee shall, within 30 days after the
occurrence of any Default with respect to the Notes, 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 Notes or a
Default or Event of Default in complying with "-- Certain Covenants -- Merger,
Sale of Assets, etc.," 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.
 
     No Holder will have any right to institute any proceeding with respect to
the 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 of Notes 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 of the
outstanding Notes a direction inconsistent with such request. However, such
limitations do not apply to a suit instituted by a Holder of any Note for
enforcement of payment of the principal of or interest on such Note on or after
the due date therefor (after giving effect to the grace period specified in
clause(b) of the first paragraph of this "-- Events of Default" section).
 
     The Company will be required to furnish to the Trustee after the end of
each fiscal year a statement as to the performance by it of certain of its
obligations under the Indenture and as to any default in such performance.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATOR AND
STOCKHOLDERS
 
     No director, officer, employee, incorporator or stockholder of the Company
or any of its Affiliates, as such, shall have any liability for any obligations
of the Company or any of its Affiliates under the Notes or the Indenture or for
any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of
the Notes.
 
SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE
 
     The Company may terminate its substantive obligations in respect of the
Notes by delivering all outstanding Notes to the Trustee for cancellation and
paying all sums payable by it on account of principal of, premium, if any, and
interest on all Notes or otherwise. In addition to the foregoing, the Company
may terminate the applicability of the covenants under "-- Certain Covenants"
and "-- Change of Control" or any Event of Default under clause (e) of
"-- Events of Default" by (i) depositing with the Trustee, under the terms of an
irrevocable trust agreement, money or United States Government Obligations
sufficient (without reinvestment) to pay all remaining indebtedness on such
Notes 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 Notes 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 United States Investment
Company Act of 1940, as amended (the "Investment Act"); and (iv) complying with
certain other requirements set forth in the Indenture. In addition, the Company
may, provided that no Default has occurred and is continuing or would arise
therefrom (or, with respect to a Default specified in clause (h) of "-- Events
of Default," occurs at any time on or prior to the 91st calendar day after the
date of the deposit (it being understood that this condition shall not be deemed
satisfied until after such 91st day)) under the Indenture, terminate all of its
substantive obligations in respect of the Notes (including its obligations to
pay the principal of and interest on such Notes) by (i) depositing with the
Trustee, under the terms of an irrevocable trust agreement, money or United
States Government Obligations sufficient (without reinvestment) to pay all
 
                                       71
<PAGE>   78
 
remaining Indebtedness on such Notes 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 such Notes 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 the 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, such Trustee or the relevant 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 Act; and (iv) complying with certain other
requirements set forth in the Indenture.
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of a majority in aggregate
principal amount of the Notes (including consents obtained in connection with a
tender offer or exchange offer for such Notes); provided, however, that no such
modification or amendment to the Indenture may, without the consent of the
Holder of each Note affected thereby, (a) change the maturity of the principal
of any such Note; (b) alter the optional redemption or repurchase provisions of
any such Note or the Indenture in a manner adverse to the Holders of such Notes;
(c) reduce the principal amount of any such Note; (d) reduce the rate of or
extend the time for payment of interest on any such Note; (e) change the place
or currency of payment of principal of or interest on any such Note; (f) modify

or with respect to any such Note in respect thereof or the modification and
amendment provisions of the Indenture and such Notes (other than to add sections
of the Indenture or such Notes which may not be amended, supplemented or waived
without the consent of each Holder therein affected); (g) reduce the percentage
of the principal amount of outstanding Notes necessary for amendment to or
waiver of compliance with any provision of the Indenture or the Notes or for
waiver of any Default in respect thereof; (h) waive a default in the payment of
principal of, interest on, or redemption payment with respect to, such Note
(except a rescission of acceleration of the relevant Notes by the Holders
thereof as provided in the Indenture and a waiver of the payment default that
resulted from such acceleration); (i) modify the ranking or priority of any such
Note; (j) modify the provisions of any covenant (or the related definitions) in
the Indenture requiring the Company to make an Offer to Purchase in a manner
materially adverse to the Holders of Notes affected thereby; or (k) modify the
provisions of the Escrow Agreement or the Indenture relating to the Escrow
Collateral in any manner adverse to the Holders or release any of the Escrow
Collateral from the Lien under the Escrow Agreement or permit any other
obligation to be secured by the Escrow Collateral.
 
     The Holders of a majority in aggregate principal amount of the outstanding
Notes, on behalf of all Holders, may waive compliance by the Company with
certain restrictive provisions of the Indenture. Subject to certain rights of
the Trustee as provided in the Indenture, the Holders of a majority in aggregate
principal amount of the Notes, on behalf of all Holders, may waive any past
default under the Indenture (including any such waiver obtained in connection
with a tender offer or exchange offer for such Notes), except a default in the
payment of principal or interest or a default arising from failure to purchase
any Notes tendered pursuant to an Offer to Purchase pursuant thereto, or a
default in respect of a provision that under the Indenture cannot be modified or
amended without the consent of the Holder of each Note that is affected.
 
GOVERNING LAW
 
     The Indenture and the Notes will be governed by the laws of the State of
New York without regard to principles of conflicts of laws.

<PAGE>   79
 
THE TRUSTEE
 
     Except during the continuance of a Default, the Trustee will perform only
such duties as are specifically set forth in the Indenture. During the existence
of a Default under the Indenture, the Trustee will exercise such rights and
powers vested in it under the Indenture and use the same degree of care and
skill in its exercise as a prudent person would exercise under the circumstances
in the conduct of such person's own affairs.
 
     The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of the Company or any other obligor upon the Notes, to obtain
payment of claims in certain cases or to realize on certain property received by
it in respect of any such claim as the Notes or otherwise. The Trustee is
permitted to engage in other transactions with the Company or an Affiliate of
the Company; provided, however, that if it acquires any conflicting interest (as
defined in the Indenture or in the Trust Indenture Act), it must eliminate such
conflict or resign.

Refinanced only with Indebtedness that is made pari passu with or subordinate in

REGISTRATION RIGHTS; ADDITIONAL INTEREST
 
     Holders of Exchange Notes are not entitled to any registration rights with
respect to the Exchange Notes. Pursuant to the Registration Rights Agreement,
the Company has agreed to file with the Commission on or before the Filing Date,
an offer to exchange (the "Exchange Offer") any and all of the Registrable
Securities for a like aggregate principal amount of senior debt securities of
the Company which are identical to the Outstanding Notes (the "Exchange
Securities") (and which are entitled to the benefits of the Indenture or a trust
indenture which is substantially identical to the Indenture (other than such
changes as are necessary to comply with any requirements of the Commission to
effect or maintain the qualification of such trust indenture under the Trust
Indenture Act (the "TIA")) and which has been qualified under the TIA), except
that the Exchange Securities shall have been registered pursuant to an effective
registration statement under the Securities Act and shall contain no restrictive
legend thereon. The Exchange Notes are intended to constitute Exchange
Securities under the Registration Rights Agreement. The Company has agreed to
use its reasonable best efforts to (i) cause such registration statement to
become effective and commence the Exchange Offer on or prior to the
Effectiveness Date, (ii) keep the Exchange Offer open for 30 days (or longer if
required by applicable law) (the last day of such period, the "Expiration Date")
and (iii) exchange Exchange Securities for all Notes validly tendered and not
withdrawn pursuant to the Exchange Offer on or prior to the fifth day following
the Expiration Date. The Company will cause a copy of any notice regarding the
Exchange Offer to be published in a daily newspaper with general circulation in
Luxembourg (which is expected to be the Luxemburger Wort).
 
     The Company has agreed to use its reasonable best efforts to keep such
registration statement effective and to amend and supplement the prospectus
contained therein in order to permit such prospectus to be lawfully delivered by
all persons subject to the prospectus delivery requirements of the Securities
Act for at least 180 days (or such shorter time as such persons must comply with
such requirements in order to resell the Exchange Securities) (the "Applicable
Period").
 
     The Exchange Offer and the Registration Statement (of which this Prospectus
constitutes a part) filed in connection with the Exchange Offer are intended to
satisfy the Company's obligations under the Registration Rights Agreement. If
the Company does not consummate the Exchange Offer, or, in lieu thereof, the
Company does not file and cause to become effective a resale shelf registration
for the Notes within the time periods set forth herein, special interest will
accrue and be payable on the Notes either temporarily or permanently.
 
     Although the Company has filed the Registration Statement in satisfaction
of its obligations under the Registration Rights Agreement, as previously
described, there can be no assurance that the Registration Statement will become
effective. If, (i) because of any change in law or in currently prevailing
interpretations of the Staff of the Commission, the Company is not permitted to
effect the Exchange Offer, (ii) the Exchange Offer is not commenced on or prior
to the Effectiveness Date, (iii) the Exchange Offer is not, for any reason,
consummated on or prior to the 165th day after the Issue Date, (iv) any Holder
of Private Exchange Securities (as defined in the Registration Rights Agreement)
so requests, or (v) in the case of any Holder that
 
                                       85
<PAGE>   92
 
participates in the Exchange Offer, such Holder does not receive Exchange
Securities on the date of the exchange that may be sold without restriction
under state and federal securities laws (the occurrence of any such event, a
"Shelf Registration Event"), then, in the case of each of clauses (i) to and
including (v) of this sentence, the Company shall promptly deliver to the
Holders and the Trustee notice thereof (the "Shelf Notice") and shall thereafter
file an Initial Shelf Registration Statement pursuant to the terms of the
Registration Rights Agreement.
 
  SHELF REGISTRATION
 
     If a Shelf Registration Event has occurred (and whether or not this
Registration Statement has become effective, or the Exchange Offer has been
consummated), then:
 
          Initial Shelf Registration Statement.  The Company shall promptly
     prepare and file with the Commission a Registration Statement for an
     offering to be made on a continuous basis pursuant to Rule 415 covering all
     of the Registrable Securities (the "Initial Shelf Registration Statement").
     The Company shall file with the Commission the Initial Shelf Registration
     Statement on or prior to the Filing Date. The Initial Shelf Registration
     Statement shall be on Form S-1 or another appropriate form if available,
     permitting registration of such Registrable Securities for resale by such
     holders in the manner designated by them (including, without limitation, in
     one or more underwritten offerings). The Company shall not permit any
     securities other than the Registrable Securities to be included in the
     Initial Shelf Registration Statement or any Subsequent Shelf Registration
     Statement. The Company shall use its reasonable best efforts to cause the
     Initial Shelf Registration Statement to be declared effective under the
     Securities Act on or prior to the Effectiveness Date, and to keep the
     Initial Shelf Registration Statement continuously effective under the
     Securities Act until the date which is 24 months from the Issue Date (or
     such shorter period under Rule 144 under the Securities Act then in effect
     permitting resales of securities by non-affiliates of the issuer without
     registration), or such shorter period ending when (i) all Registrable
     Securities covered by the Initial Shelf Registration Statement have been
     sold in the manner set forth and as contemplated in the Initial Shelf
     Registration Statement or (ii) a Subsequent Shelf Registration Statement
     covering all of the Registrable Securities has been declared effective
     under the Securities Act (such period, the "Effectiveness Period").
 
          Subsequent Shelf Registration Statements.  If the Initial Shelf
     Registration Statement or any Subsequent Shelf Registration Statement
     ceases to be effective for any reason at any time during the Effectiveness
     Period (other than because of the sale of all of the securities registered
     thereunder), the Company shall use its reasonable best efforts to obtain
     the prompt withdrawal of any order suspending the effectiveness thereof,
     and in any event the Company shall within 45 days of such cessation of
     effectiveness amend the Shelf Registration Statement in a manner reasonably
     expected to obtain the withdrawal of the order suspending the effectiveness
     thereof, or file an additional "shelf" Registration Statement pursuant to
     Rule 415 covering all of the Registrable Securities (a "Subsequent Shelf
     Registration Statement"). If a Subsequent Shelf Registration Statement is
     filed, the Company shall use its reasonable best efforts to cause the
     Subsequent Shelf Registration Statement to be declared effective as soon as
     reasonably practicable after such filing and to keep such Registration
     Statement continuously effective until the end of the Effectiveness Period.
     As used herein the term "Shelf Registration Statement" means the Initial
     Shelf Registration Statement and any Subsequent Shelf Registration
     Statement.
 
          Supplements and Amendments.  The Company shall promptly supplement and
     amend the Shelf Registration Statement if required by the rules,
     regulations or instructions applicable to the registration form used for
     such Shelf Registration Statement, if required by the Securities Act, or if
     reasonably requested by the Holders of a majority in aggregate principal
     amount of the Registrable Securities covered by such Registration Statement
     or by any underwriter of such Registrable Securities.

the Notes ("Additional Interest") under the circumstances and to the extent set
forth below (each of which shall be given independent effect):

     described in clause (i) of the third paragraph under "-- Exchange Offer"
     above shall have occurred prior to the Filing Date), Additional Interest
     shall accrue on the Notes over and above the stated interest on the
     principal at a rate equal to 50 basis points for the first 90 days (for any
     part thereof), immediately following such date, such Additional Interest
     increasing by an additional 50 basis points for each subsequent 90-day
     period (or any part thereof);
 
          (ii) if either the Registration Statement or the Initial Shelf
     Registration Statement is not declared effective by the Commission on or
     prior to the Effectiveness Date (unless, with respect to the Registration
     Statement, a Shelf Event described in clause (i) of the third paragraph
     under "-- Exchange Offer" above shall have occurred), Additional Interest
     shall accrue on the Notes included or which should have been included in
     such Registration Statement over and above the stated interest on the
     principal at a rate equal to 50 basis points for the first 90 days (for any
     part thereof), immediately following the day after such date, such
     Additional Interest increasing by an additional 50 basis points for each
     subsequent 90-day period (or any part thereof); and
 
          (iii) if (A) the Company has not exchanged Exchange Securities for all
     Notes validly tendered and not withdrawn in accordance with the terms of
     the Exchange Offer on or prior to the fifth day after the Expiration Date,
     or (B) the Registration Statement ceases to be effective at any time prior
     to the Expiration Date, or (C) if applicable, any Shelf Registration
     Statement has been declared effective and such Shelf Registration Statement
     ceases to be effective at any time during the Effectiveness Period, then
     Additional Interest shall accrue on the Notes (over and above any interest
     otherwise payable on principal of the Notes) in an amount equal to 50 basis
     points for the first 90 days (or any part thereof) commencing on the (x)
     sixth day after the Expiration Date, in the case of (A) above, or (y) the
     day the Registration Statement ceases to be effective in the case of (B)
     above, or (z) the day such Shelf Registration Statement ceases to be
     effective in the case of (C) above, such Additional Interest increasing by
     an additional 50 basis points at the beginning of each such subsequent
     90-day period (or any part thereof);
 
   
provided, however, that the Additional Interest rate on the Notes may not exceed
at any one time in the aggregate 150 basis points, provided further, that (1)
upon the filing of the Exchange Offer Registration Statement or a Shelf
Registration Statement as required hereunder (in the case of clause (i) of this
paragraph), (2) upon the effectiveness of the Registration Statement or the
Shelf Registration Statement as required hereunder (in the case of clause (ii)

ceased to remain effective (in the case of (iii)(B) of this paragraph), or upon
the effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of (iii)(C) of paragraph), Additional Interest on the
Notes as a result of such clause (or the relevant subclause thereof), as the
case may be, shall cease to accrue (but any accrued amount shall be payable).

                           CERTAIN TAX CONSIDERATIONS
 
     The following is a summary of the principal Netherlands and United States
federal tax consequences to U.S. Holders (as defined below) of the exchange of
Outstanding Notes for Exchange Notes pursuant to the Exchange Offer and the
ownership and disposition of Exchange Notes by a holder acquiring the Exchange
Notes pursuant to the Exchange Offer. The summary is based on the opinion of
Shearman & Sterling as to United States federal income tax matters. This
discussion is not exhaustive of all the possible tax considerations and
potential investors are advised to consult their own tax advisors in order to
determine the final tax consequences of exchanging Outstanding Notes for
Exchange Notes in their own particular circumstances.
 
THE NETHERLANDS
 
     This summary is based on the tax laws of the Netherlands, as well as the
Convention between the United States of America and the Kingdom of the
Netherlands for the Avoidance of Double Taxation and the Prevention of Fiscal
Evasion with respect to Taxes on Income (the "Treaty"), to the extent they were
published and effective on October 1, 1997. Changes made to these laws after
that date may have retroactive effect, and may affect the tax consequences
described herein.
 
   
     The outline below is based on the assumption that the U.S. Holder is not,
and has not been for at least five years, a resident of the Netherlands for
purposes of Dutch tax legislation and is not engaged in a trade or business
through a branch or agency in the Netherlands and does not have a permanent
establishment therein (a "Non-Resident Holder"). In addition, it is assumed that
holders who are individuals do not own, either alone or together with related
individuals, 25% or more of any class of shares of HER Finally it is assumed
that the limitation on benefits provision in the Treaty cannot be invoked
against the holder.
    
 
  GENERAL APPLICATION OF DUTCH TAX LAW
 
   
     A Non-Resident Holder of Notes is liable for Corporate or Individual Income
Tax ("CIT" or "IIT"), according to Dutch Law, if he/she receives interest with
respect to the Notes provided that either (i) he or she has, directly or
indirectly, a substantial interest or a deemed substantial interest (as defined
below) in HER or (ii) such interest is attributable to a Dutch enterprise.
Similarly, the capital gains realized upon sale of the Outstanding Notes are
only taxable if the Notes are (deemed to be) part of such "substantial"
interest.
    
 
   
     A substantial interest is deemed to exist if the Non-Resident Holder,
either alone or together with related individuals, owns at least five percent of
the share capital in any class of shares issued by HER or if he/she holds an
option to buy at least 5% in any class of shares in the capital of HER
    
 
  INTEREST -- WITHHOLDING TAX AND TAX TREATY LIMITATIONS
 
     According to article 12 of the Treaty, interest can only be subject to
CIT/IIT in the country of residence of the recipient of the interest. As a
result, no Dutch CIT or IIT will be due on interest received on the Notes.
 
     In addition, the Netherlands does not levy any withholding taxes on the
payment of interest, provided that these payments do not depend and/or are not
deemed to be dependent on the profits realized and/or distributed by the company
paying the interest. If such link can be established, payments are likely to be
reclassified as payments of dividends. Although amounts reclassified as
dividends generally would be subject to Dutch withholding tax when paid to a
Non-Resident Holder, it does not appear that any substantial basis exists for
such reclassification. The forced reduction under the Treaty of the maximum
withholding tax to zero in such a case would, however, be irrelevant.
 
  CAPITAL GAINS
 
     As a result of article 14 of the Treaty, the Dutch intention to impose CIT
or IIT on capital gains realized upon disposal of any or all of the Notes by a
Non-Resident Holder can only be effectuated, where a Holder who is an
individual, at the time of the alienation, owns, either alone or together with
related individuals, at least 25% of any class of shares of the Company.

  EXCHANGE OFFER
 
     Pursuant to the Exchange Offer contemplated by the Company herein, an
exchange of Outstanding Notes for Exchange Notes will not be a taxable event for
Netherlands income tax purposes.
 
THE UNITED STATES
 
     The following is a summary of the principal U.S. federal income tax
considerations relevant to the purchase, ownership and disposition of the Notes.
This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), existing and proposed Treasury Regulations, revenue rulings,
administrative interpretations and judicial decisions (all as currently in
effect and all of which are subject to change, possibly with retroactive
effect). Except as specifically set forth herein, this summary deals only with
Notes held as capital assets within the meaning of Section 1221 of the Code.
This summary does not discuss all of the tax consequences that may be relevant
to holders in light of their particular circumstances or to holders subject to
special tax rules, such as insurance companies, dealers in securities or foreign
currencies, tax-exempt investors, persons holding the Notes as part of a hedging
transaction, "straddle," conversion transaction, or other integrated
transaction, or U.S. Holders whose functional currency (as defined in Section
985 of the Code) is not the U.S. dollar. Persons considering the exchange of
Outstanding Notes for Exchange Notes should consult with their own tax advisors
with regard to the application of the U.S. federal income tax laws to their
particular situations as well as any tax consequences arising under the laws of
any state, local or foreign jurisdiction.
 
     As used herein, the term "U.S. Holder" means a beneficial owner of a Note
who or that is for U.S. federal income tax purposes (i) a citizen or individual
resident of the United States, (ii) a corporation created or organized in or
under the laws of the United States or any political subdivision thereof, (iii)
a domestic partnership within the meaning of the Code (i.e., a partnership
created or organized in or under the laws of the United States or any political
subdivision thereof, unless future Treasury regulations provide otherwise), (iv)
an estate the income of which is subject to U.S. federal income taxation
regardless of its source, or (v) a trust if both: (A) a U.S. court is able to
exercise primary supervision over the administration of the trust, and (B) one
or more U.S. persons have the authority to control all substantial decisions of
the trust. A "Foreign Holder" means a holder of Notes who or that is not a U.S.
Holder.
 
  INTEREST
 
     Interest on the Notes and Additional Amounts, if any, paid in respect of
withholding taxes imposed on payments on the Notes (as described in "Description
of the Notes -- Payments of Additional Amounts") generally will be taxable to a
U.S. Holder as ordinary income at the time accrued or received, in accordance
with such U.S. Holder's method of accounting for U.S. federal income tax
purposes. The amount of interest required to be included in income by a U.S.
Holder will include the amount of such taxes, if any, withheld by the Company in
respect thereof. Thus, in the event of such withholding, a U.S. Holder would be
required to report gross income in an amount greater than the cash it receives
in respect of payments on its Note. However, a U.S. Holder could, subject to
certain limitations, be eligible to claim as a credit or deduction for purposes
of computing its U.S. federal income tax liability such taxes withheld,
notwithstanding that the payment of such taxes will be made by the Company. The
rules relating to foreign tax credits and the timing thereof are extremely
complex and U.S. Holders should consult with their own tax advisors with regard
to the availability of a foreign tax credit and the application of the foreign
tax credit limitations to their particular situations.
 
  EXCHANGE OFFER; ADDITIONAL INTEREST; ADDITIONAL AMOUNTS
 
   
     Pursuant to the Exchange Offer contemplated by the Company herein, in the
opinion of Shearman & Sterling an exchange of Outstanding Notes for Exchange
Notes will not be a taxable event for U.S. federal income tax purposes and a
U.S. Holder will have the same tax basis and holding period in the Exchange
Notes as in the Outstanding Notes. The Company will be required to pay
Additional Interest in certain circumstances as described in "Description of
Notes -- Registration Rights; Additional Interest" herein. Also, subject to
certain exceptions, the Company will pay Additional Amounts to Holders in the
event that withholding taxes are imposed in respect to payments on the Notes.
See "Description of the Notes --
    
 
                                       90
<PAGE>   97
 
Additional Amounts." According to the Treasury Regulations, the possibility of
additional payments in respect of the Notes will not affect their yield (and,
accordingly, will not affect the inclusion of interest in income) if the
likelihood of such payments, as of the date the Notes are issued, is remote. The
Company does not intend to treat the possibility of additional interest as
affecting the yield to maturity of any Note. If, however, additional payments
are made on the Notes, then, solely for the purposes of determining the yield to
maturity of a Note, the Note could be treated as reissued with "original issue
discount," which could result in a U.S. Holder having to include amounts in
income prior to the receipt of payments in respect thereof.
 
  MARKET DISCOUNT AND PREMIUM
 
     If a U.S. Holder purchases a Note for an amount that is less than its
principal amount, the amount of the difference will be treated as "market
discount" for U.S. federal income tax purposes, unless such difference is less
than a specified de minimis amount.
 
     Under the market discount rules of the Code, a U.S. Holder will be required
to treat any partial principal payment on, or any gain realized on the sale,
exchange, retirement or other disposition of, a Note as ordinary income to the
extent of the lesser of (i) the amount of such payment or realized gain or (ii)
the market discount that has not previously been included in income and is
treated as having accrued on such Note at the time of such payment or
disposition. If such Note is disposed of in a nontaxable transaction (other than
a nonrecognition transaction described in Code Section 1276(c)), the amount of
gain realized on such disposition for purposes of the market discount rules
shall be determined as if such holder had sold the Note at its then fair market
value. Market discount will be considered to accrue on a straight-line basis
during the period from the date of acquisition to the maturity date of the Note,
unless the U.S. Holder elects to accrue on the basis of a constant interest
rate.
 
     A U.S. Holder may be required to defer the deduction of all or a portion of
the interest paid or accrued on any indebtedness incurred or maintained to
purchase or carry such Note until the maturity of the Note or its earlier
disposition (except for certain nonrecognition transactions). However, a U.S.
Holder may elect to include market discount in income currently as it accrues
(on either a straight-line or a constant interest rate basis), in which case the
rules described above regarding the treatment as ordinary income of gain upon
the disposition of the Note and upon the receipt of certain cash payments and
regarding the deferral of interest deductions will not apply.
 
     If a U.S. Holder purchases a Note for an amount that is greater than the
amount payable at maturity (or on the earlier call date, in the case of a Note
that is redeemable at the option of the Company), such holder will be considered
to have purchased such Note with "amortizable bond premium" equal in amount to
such excess, and may elect (in accordance with applicable Code provisions) to
amortize such premium, using a constant yield method over the remaining term of
the Note and to offset interest otherwise required to be included in income in
respect of such Note during any taxable year by the amortized amount of such
excess for such taxable year. However, if such Note may be optionally redeemed
after the U.S. Holder acquires it at a price in excess of its stated redemption
price at maturity, special rules would apply which could result in a deferral of
the amortization of some bond premium until later in the term of such Note. If
an election to amortize bond premium is not made, a U.S. Holder must include the
full amount of each interest payment in income in accordance with such U.S.
Holder's regular method of accounting and will receive a tax benefit from the
premium only in computing its gain or loss upon the sale or other disposition or
payment of the principal amount of the Note.
 
     U.S. Holders are permitted to elect to include all interest on a Note using
the constant yield method. For this purpose, interest includes stated interest,
acquisition discount, market discount, de minimis market discount, and unstated
interest, as adjusted by any amortizable bond premium or acquisition premium.
Special rules apply to such elections made with respect to Notes with
amortizable bond premium or market discount and U.S. Holders considering such an
election should consult with their own tax advisors. Once made, the election
cannot be revoked without the consent of the IRS.
 
  DISPOSITIONS
 
     Upon the sale, exchange or retirement of a Note, a U.S. Holder generally
will recognize taxable gain or loss equal to the difference between the amount
realized on the sale, exchange or retirement and such holder's adjusted tax
basis (as increased by any market discount previously includible in income by
the U.S. Holder
 
                                       91
<PAGE>   98
 
and decreased by amortizable bond premium, if any, deducted over the term of the
Notes) in the Note. For these purposes, the amount realized on the sale,
exchange or retirement of a Note does not include any amount attributable to
accrued but unpaid interest, which will be taxable as such unless previously
taken into account. Gain or loss recognized on the sale, exchange or retirement
of a Note will be capital gain or loss and will be long-term capital gain or
loss if the Note was held for more than one year. Under recently enacted
legislation, an individual generally will be taxed on the net amount of his or
her capital gain derived in respect of the Notes at a maximum rate of (i) 28%,
for Notes held for more than one year but not more than 18 months, or (ii) 20%,
for Notes held for more than 18 months. Special rules (and generally lower
maximum rates) apply for individuals in lower tax brackets.
 
  BACKUP WITHHOLDING
 
     "Backup" withholding and information reporting requirements may apply to
certain payments of principal and interest on a Note and to certain payments of
proceeds of the sale or retirement of a Note. The Company, its agent, a broker,
the Trustee or any paying agent, as the case may be, will be required to
withhold tax from any payment that is subject to backup withholding at a rate of
31% of such payment if the U.S. Holder fails to furnish his taxpayer
identification number (social security number or employer identification number)
within a reasonable time after a request therefor, to certify that such U.S.
Holder is not subject to backup withholding, or to otherwise comply with the
applicable requirements of the backup withholding rules. Certain U.S. Holders
(including, among others, all corporations) are not subject to the backup
withholding and information reporting requirements.
 
     Under current Treasury Regulations, backup withholding and information
reporting will not apply to payments made by the Company or any agent thereof
(in its capacity as such) to a Holder of a Note who has provided certain
required certification under penalties of perjury that it is not a U.S. Holder
or has otherwise established an exemption (provided that neither the Company nor
such agent has actual knowledge that the Holder is a U.S. Holder or that the
conditions of any other exemption are in fact satisfied).
 
     Payment of the proceeds from the sale by a U.S. Holder of a Note made to or
through a non-U.S. office of a broker will not be subject to U.S. information
reporting or backup withholding, except that, if the broker is a U.S. person, a
controlled foreign corporation for U.S. federal income tax purposes or a foreign
person 50% or more of whose gross income is effectively connected with a United
States trade or business for a specified three-year period, U.S. information
reporting, but not backup withholding, may apply to such payments. Payments of
the proceeds from the sale of a Note to or through the United States office of a
broker are subject to U.S. information reporting and backup withholding unless
the Holder certifies as to its non-U.S. status or otherwise establishes an
exemption from U.S. information reporting and backup withholding.
 
     Any amounts withheld under the backup withholding rules from a payment to a
Holder may be claimed as a credit against such Holder's U.S. federal income tax
liability; provided that the required information is provided to the IRS.
 
  FOREIGN HOLDERS
 
     Foreign Holders generally will not be subject to U.S. federal income or
withholding tax on (a) interest and Additional Amounts, if any, in respect of
the Notes unless such payments are effectively connected with the conduct by the
Foreign Holder of a trade or business within the United States, or (b) gains
realized on the sale, exchange or retirement of a Note unless (i) such gain is
effectively connected with the conduct by the Foreign Holder of a trade or
business within the United States or (ii) in the case of gain realized by an
individual Foreign Holder, the Foreign Holder is present in the United States
for 183 days or more in the taxable year of the disposition and certain other
conditions are met.
 
     Notes held (or treated as held) by an individual who is a Foreign Holder at
the time of his or her death will not be subject to U.S. federal estate tax,
provided that any interest on the Notes would have qualified as portfolio
interest if received by such individual at the time of his or her death.

                              PLAN OF DISTRIBUTION
 
     Based on positions taken by the staff of the Commission set forth in
no-action letters issued to Exxon Capital Holdings Corp. and Morgan Stanley &
Co. Inc., among others, the Company believes that Exchange Notes issued pursuant
to the Exchange Offer in exchange for Outstanding Notes may be offered for
resale, resold and otherwise transferred by holders thereof (other than any
holder which is (i) an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act, (ii) a broker-dealer who acquired Notes directly from
the Company, or (iii) broker-dealers who acquired Notes as a result of
market-making or other trading activities) without compliance with the
registration and prospectus delivery provisions for the Securities Act provided
that such Exchange Notes are acquired in the ordinary course of such holders'
business, and such holders are not engaged in, and do not intend to engage in,
and have no arrangement or understanding with any person to participate in, a
distribution of such Exchange Notes; provided that broker-dealers
("Participating Broker-Dealers") receiving Exchange Notes in the Exchange Offer
will be subject to a prospectus delivery requirement with respect to resales of
such Exchange Notes. To date, the staff of the Commission has taken the position
that Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to transactions involving an exchange of securities
such as the exchange pursuant to the Exchange Offer (other than a resale of an
unsold allotment from the sale of the Outstanding Notes to the Initial
Purchasers thereof) with the Prospectus contained in the Exchange Offer
Registration Statement. Pursuant to the Registration Rights Agreement, the
Company has agreed to permit Participating Broker-Dealers and other persons, if
any, subject to similar prospectus delivery requirements to use this Prospectus
in connection with the resale of such Exchange Notes. The Company has agreed
that, for a period of 180 days after the Exchange Offer has been consummated, it
will make this Prospectus, and any amendment or supplement to this Prospectus,
available to any broker-dealer that requests such documents in the Letter of
Transmittal.
 
     Each holder of Outstanding Notes who wishes to exchange its Outstanding
Notes for Exchange Notes in the Exchange Offer will be required to make certain
representations to the Company as set forth in "Terms of the Exchange
Offer -- Terms and Conditions of the Letter of Transmittal". In addition, each
holder who is a broker-dealer and who receives Exchange Notes for its own
account in exchange for Outstanding Notes that were acquired by it as a result
of market-making activities or other trading activities, will be required to
acknowledge that it will deliver a prospectus in connection with any resale by
it of such Exchange Notes.
 
     Holders who tender Outstanding Notes in the Exchange Offer with the
intention to participate in a distribution of the Exchange Notes may not rely
upon the Morgan Stanley or similar no-action letters.
 
     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or at negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
such broker-dealer and/or the purchasers of any such Exchange Notes. The Letter
of Transmittal states that by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter' within the meaning of the Securities Act.
 
     The Company has agreed to pay all expenses incidental to the Exchange Offer
other than commissions and concessions of any brokers or dealers and will
indemnify holders of the Outstanding Notes (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act, as
set forth in the Registration Rights Agreement.

spurs which branch off the through-portions.
 
     Bandwidth.  The range of frequencies that can be passed through a medium,
such as glass fibers, without distortion. The greater the bandwidth, the greater
the information-carrying capacity of such medium. For fiber optic transmission,
electronic transmitting devices determine the bandwidth, not the fibers
themselves. Bandwidth is measured in Hertz (analog) or Bits Per Second
(digital).

services.
 
     Frame Relay.  A wide area transport technology that organizes data into
units called frames instead of providing fixed bandwidth as with private lines.
A high-speed, data-packet switching service used to transmit data between
computers. Frame Relay supports data units of variable lengths at access speeds
ranging from 56 kilobits per second to 1.5 megabits per second. This service is
well-suited for connecting local area networks, but is not presently well suited
for voice and video applications due to the variable delays which can occur.
Frame Relay was designed to operate at high speeds on modern fiber optic
networks.

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.

tell the switch where to route the call. The switch opens or closes circuits or
selects the paths or circuits to be used for transmission of information.
Switching is a process of interconnection circuits to form a transmission path
between users. Switches allow local telecommunications service providers to
connect calls directly to their destination, while providing advanced features
and recording connection information for future billing.
 
     Synchronous Digital Hierarchy (SDH).  SDH is a set of standards for optical
communications transmission systems that define optical rates and formats,
signal characteristics, performance, management and maintenance information to
be embedded within the signals and the multiplexing techniques to be employed in
optical communications transmission systems. SDH facilitates the
interoperability of dissimilar vendors' equipment and benefits customers by
minimizing the equipment necessary for telecommunications applications. SDH also
improves the reliability of the local loop connecting customers' premises to the
local exchange provider, historically one of the weakest links in the service
delivery.

                 REPORT OF ERNST & YOUNG, INDEPENDENT AUDITORS
 
To the Board of Directors and
the Shareholders of
Hermes Europe Railtel B.V.
 
     We have audited the accompanying consolidated balance sheets of Hermes
Europe Railtel B.V. (a development stage company) as of December 31, 1995 and
1996, and the related consolidated statements of operations, cash flows, and
shareholders' equity for the years ended December 31, 1995 and 1996. 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 consolidated financial position of Hermes Europe
Railtel B.V. at December 31, 1995 and 1996, and the consolidated results of its
operations and its cash flows for the years then ended in conformity with United
States generally accepted accounting principles.

                           HERMES EUROPE RAILTEL B.V.
                         (A DEVELOPMENT STAGE COMPANY)
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1:  NATURE OF BUSINESS OPERATIONS
 
     Hermes Europe Railtel B.V. (the "Company") intends to become the leading
pan-European carriers' carrier by constructing and operating a managed,
seamless, fiber optic, pan-European network, and providing high-quality
trans-border transmission services to telecommunications carriers across Europe.
 
     The Company is 50% owned by HIT Rail B.V.("HIT Rail"), a consortium of
eleven European railway companies and 50% owned by GTS-Hermes,
Inc.("GTS-Hermes"), a U.S. holding company that is a wholly-owned subsidiary of
Global TeleSystems Group, Inc., a provider of a broad range of
telecommunications services to businesses, other telecommunications service
providers and consumers through its operations of voice and data networks,
international gateways, local access and cellular networks and the provision of
various value added services in markets outside of the United States.
 
     The Company is still a development stage enterprise, as currently the
telecommunications network is being configured. The buildout of the network
started in 1996; full commercial services are anticipated to commence in the
first half of 1998.
 
     The Company had working deficits of approximately $4.4 million and $0.4
million as of December 31, 1996 and 1995, respectively. The Company had an
accumulated deficit of $22.7 million as of December 31, 1996, including a net
loss of approximately $16.0 million for the year then ended. During 1997, the
Company expects to incur substantial expenditures for working capital and
capital expenditure requirements. The Company's working capital at December 31,
1996, plus its anticipated cash flows from operations for 1997, will not be
sufficient to meet such objectives as presently planned.
 
     Management recognizes that the Company must generate additional capital
resources in order to continue its buildout of the network. The Company is
pursuing other equity and debt financing sources and has entered into
substantive negotiations with various financial institutions in order to obtain
further debt financing and is expecting to complete a recapitalization (the
"Recapitalization") by the end of August, 1997 (see Note 9, "Subsequent Events
and Pro Forma Adjustments").
 
     The financial statements have been prepared on the basis of accounting
principles applicable to a going concern, which assumes that the Company will
continue in the foreseeable future and will be able to realize its assets and
discharge its liabilities in the normal course of business. If the going concern
assumptions were not appropriate for these financial statements, then
adjustments would have been necessary in the carrying value of assets and
liabilities and the reported revenues and expenses.
 
NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The financial statements include the accounts of Hermes Europe Railtel
B.V., its Belgian branch and of Hermes Europe Railtel N.V. All significant
intercompany accounts and transactions are eliminated upon consolidation.
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made to the 1995 consolidated financial
statements in order to conform to the 1996 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 $3.8 million of restricted cash at December 31, 1996.

                         (A DEVELOPMENT STAGE COMPANY)
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
The restricted cash is primarily related to cash held in escrow in compliance
with an agreement with a major vendor.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost. Depreciation is calculated on a
straight-line basis over the estimated lives ranging from five to seven years
for telecommunications equipment and three to ten years for furniture, fixtures
and equipment and other property. A substantial part of the costs includes
construction in process, which is currently related to the configuration and
build-out of the network, and these costs primarily consist of labor. These
costs are transferred to telecommunications equipment in service as construction
is completed and/or equipment is placed into service. Depreciation is recorded
commencing with the first full month that the assets are in service. Maintenance
and repairs are charged to expense as incurred.
 
     The Company intends to capitalize material interest costs associated with
the construction of telecommunications equipment; however, no interest costs
have been capitalized as of December 31, 1996.
 
LONG-LIVED ASSETS
 
     Effective January 1, 1995, 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." In accordance
with SFAS No. 121, long-lived assets to be held and used by the Company are
reviewed to determine whether any events or changes in circumstances indicate
that the carrying amount of the asset may not be recoverable. For long-lived
assets to be held and used, the Company bases its evaluation on such impairment
indicators as the nature of the assets, the future economic benefit of the
assets, any historical or future profitability measurements, as well as other
external market conditions or factors that may be present. If such impairment
indicators are present or other factors exist that indicate that the carrying
amount of the asset may not be recoverable, the Company determines whether an
impairment has occurred through the use of an undiscounted cash flow analysis of
assets at the lowest level for which identifiable cash flows exist. If an
impairment has occurred, the Company recognizes a loss for the difference
between the carrying amount and the estimated value of the asset. The fair value
of the asset is measured using quoted market prices or, in the absence of quoted
market prices, fair value is based on an estimate of discounted cash flow
analysis. During the years ended December 31, 1995 and 1996, the Company's
analyses indicated that there was not an impairment of its long-lived assets.
 
INCOME TAXES
 
     The Company uses the liability method of accounting for income taxes.
Deferred income taxes result from temporary differences between the tax basis of
assets and liabilities and the basis as reported in the consolidated financial
statements.
 
FOREIGN CURRENCY TRANSLATION
 
     The accounting records of the Dutch B.V. company are maintained in Dutch
guilders. The accounting records of the Belgian branch and the Belgian N.V.
company are maintained in Belgian francs. The functional currency for the
Company has been determined to be the Belgian franc. Therefore, the Dutch
guilder statements have been remeasured into Belgian franc equivalents,
consolidated with the Belgian branch and Belgian N.V. statements and then
translated into U.S. dollar equivalents for the purpose of preparing the
accompanying financial statements, in accordance with accounting principles
generally accepted in the United States.

                         (A DEVELOPMENT STAGE COMPANY)
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     The Company follows a translation policy in accordance with SFAS No. 52,
"Foreign Currency Translation." Assets and liabilities are translated at the
rates of exchange at the balance sheet date. Income and expense accounts are
translated at average monthly rates of exchange. The resultant translation
adjustments are included in the cumulative translation adjustment, a separate
component of shareholders' equity. Gains and losses from foreign currency
transactions are included in the operations.
 
REVENUE RECOGNITION
 
     The Company's revenue is associated with its customers right to use the
network and is recognized on a straight-line basis over the terms of the
customer contracts.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company believes that the carrying amount of its assets and liabilities
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
receivable. The Company maintains most of its cash and cash equivalents in high
quality European financial institutions.
 
     The Company does not now hedge against foreign currency fluctuations,
although the Company may implement such practices in the future. Under current
practices, the Company's results from operations could be adversely affected by
fluctuations in foreign currency exchange rates.
 
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.

NOTE 5:  DEFINED BENEFIT PLAN
 
     The Company established a defined benefit pension plan in 1995 that covers
substantially all of its employees upon twenty-five years of age and at least
one year of service. The benefits are based on years of service and the
employee's compensation. The Company has entered into an arrangement with an
insurance company for the provision of a group insurance policy (the "Policy").
Under the Policy, the insurance provider has undertaken a legal obligation to
provide specified benefits to participants in return for a fixed premium;
accordingly, the Company no longer bears significant financial risk. Premium

the employees annual salary, with the remaining premium paid by the employer.
Premiums are intended to provide not only for benefits attributed to service to
date but also for those expected to be earned in the future.
 
   
     The Company's expense under the plan was $0.05 million in 1995. No
actuarial calculation was performed due to the immateriality to the financial
statements.

NOTE 7:  COMMITMENTS AND CONTINGENCIES
 
OPERATING LEASES
 
     Operating lease commitments are primarily for office space and car rental.
The office lease has a term of nine years, expiring on June 30, 2005, with an
option to cancel January 1, 2002 with a penalty of six months, rental payment as
well as the remaining principal due on the debt obligation (see Note 4, "Debt
Obligations"). In addition, the Company received a reduction in annual expense
during the first three years of the lease. This reduction is being amortized
over the first six years of the lease, using a straight-line method.
 
     Rental expense aggregated approximately $0.5 million and $0.7 million, net
of sublease income of $0.01 million and $0.08 million for the years ended
December 31, 1996 and 1995, respectively. The Company did not have rent expense
in 1994.
 
     Future minimum lease payments under these non-cancelable operating leases
with terms of one year or more, as of December 31, 1996, are as follows:
1997 -- $1.1 million, 1998 -- $1.1 million, 1999 -- $1.2 million, 2000 -- $1.2
million, 2001 -- $1.2 million and $0.6 million thereafter.
 
OTHER MATTERS
 
     In the ordinary course of business, the Company may be party to various
legal and tax proceedings, and subject to claims, certain of which relate to the
regulatory environments in which the Company currently or intends to operate. In
the opinion of management, the Company's liability, if any, in all pending
litigation, or other legal proceeding or other matter other than what is
discussed above, will not have a material effect upon the financial condition,
results of operations or liquidity of the Company.

     The amount due from GTS HER includes $0.1 million of accrued interest at
December 31, 1996. The loans will be converted into shares of the Company's
common stock as part of the Recapitalization which is expected to be completed
by the end of August, 1997 (see Note 9, "Subsequent Events and Pro Forma
Adjustments").
    
 
NOTE 9:  SUBSEQUENT EVENTS AND PRO FORMA ADJUSTMENTS
 
     Subsequent to December 31, 1996, Hermes Europe Railtel N.V. began
negotiating a new lease on a second office building, which is currently being
constructed. The terms of the lease are expected to be finalized by the fourth
quarter of 1997, the expected completion date of the construction. The lease
period will be for eight years and will have an annual expense of $0.4 million
to be paid in quarterly installments.
 
     In January and February 1997, additional loans of ECU 6.4 million
(approximately $7.5 million) were advanced to the Company by GTS-Hermes. These
loans were converted into shares of the Company's common stock ("Common Stock")
as part of the Recapitalization. In addition, loans of ECU 5.4 million
(approximately $6.1 million) were advanced to the Company in February and April
1997 by individual members of HIT Rail. These loans are expected to be converted
into Common Stock as part of the Recapitalization discussed below.
 
     To increase the equity of the Company by means of the contribution of fiber
optic cable leases and/or cash by its current partners and individual
shareholders of HIT Rail, the Company expects to complete the Recapitalization
by the end of August, 1997.
 
     Pursuant to the Recapitalization, the Company extended rights to subscribe
to additional Common Stock to GTS-Hermes, HIT Rail and the eleven individual
members of the HIT Rail consortium. HIT Rail and eight of the members of HIT
Rail have declined to exercise their rights, while GTS-Hermes and three of the
members of HIT Rail have indicated that they intend to exercise their rights.
 
     The first phase of the Recapitalization was completed on July 7, 1997. As a
result, all shareholders' loans from GTS-Hermes and HIT Rail were converted into
Common Stock. In addition, GTS-Hermes exercised its right to subscribe to
additional Common Stock, resulting in a contribution of ECU 46.0 million
(approximately $51.1 million), which will be paid to the Company by September
30, 1997. The first phase of the Recapitalization resulted in the following
ownership of the Company:

the Company by two of the individual members of HIT Rail, as well as the
contribution of fiber optic cable leases. If all three individual members of HIT
Rail participate in the Recapitalization as anticipated, it will result in the

contain all adjustments (consisting only of normal recurring accruals) necessary
to present fairly the Company's financial position as of December 31, 1996 and
September 30, 1997, and the results of operations and cash flows for the periods
indicated.
 
     Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted. Material intercompany affiliate account
transactions have been eliminated; however, other adjustments may have been
required had an audit been performed. It is suggested that these financial
statements be read in conjunction with the Company's 1996 audited consolidated
financial statements and the notes related thereto. The results of operations
for the nine months ended September 30, 1997 may not be indicative of the
operating results for the full year.
 
     The Company intends to become the leading pan-European carriers' carrier by
constructing and operating a managed, seamless, fiber optic, pan-European
network, and providing high quality trans-border transmission services to
telecommunications carriers across Europe.
 
   
     In an effort to generate sufficient capital resources to continue its
buildout of the network and sustain working capital requirements, the Company
undertook a recapitalization (the "Recapitalization") during the first quarter
of 1997, which was completed in September 1997. Prior to the recapitalization,
the Company was 50% owned by HIT Rail B.V. ("HIT Rail"), a consortium of eleven
European railway companies, and 50% owned by GTS-Hermes, Inc. ("GTS-Hermes"), a
U.S. holding company that is a wholly owned subsidiary of Global TeleSystems
Group, Inc. ("GTS"), 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 value-added services, in markets
outside the United States.
    
 
   
     Pursuant to the Recapitalization, the Company 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 the Company. GTS-Hermes and two of the
members of HIT Rail, Societe Nationale des Chemins de Fer Belges S.A. de Droit
Public/Nationale Maatschappij der Belgische Spoorwegen N.V. ("NMBS") and AB Swed
Carrier ("Swed Carrier"), 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 Recapitalization, total shareholder
loans of ECU 39.4 million (approximately $48.5 million) from, collectively,
GTS-Hermes, HIT Rail, NMBS and Swed Carrier were converted into equity.
Additionally, GTS-Hermes contributed ECU 46.0 million (approximately $51.8
million) and NMBS contributed a ten-year fiber optic cable lease which was
valued at ECU 1.8 million (approximately $2.0 million).
    
 
     In addition, under Dutch law, the Company is required to pay a 1% capital
duty tax on issuances of common stock, resulting in a tax of approximately $1.0
million, of which $0.6 million remains to be paid at September 30, 1997.

</TABLE>
 
     In an additional effort to obtain capital resources, the Company completed
a debt offering in August 1997 that raised $265.0 million (see Note 2, "Debt
Obligations").
 
     The Company was a development stage enterprise through December 31, 1996.
 
NOTE 2.  DEBT OBLIGATIONS
 
   
     On August 15, 1997, the Company issued aggregate principal amount $265.0
million of senior notes due August 15, 2007 (the "Senior Notes"). The Senior
Notes are general unsecured obligations of the Company, with interest payable
semiannually at a rate of 11.5%. Approximately $56.6 million of the net proceeds
of the offering of the Senior Notes is being held in escrow for the first four
semiannual interest payments commencing on February 15, 1998. The Company may
redeem the Senior Notes, in whole or in part, any time on or after August 15,
2002 at specific redemption prices. The Company may also redeem the Senior Notes
at a price equal to 111.5% of the principal amount prior to August 15, 2000 with
net cash proceeds of a public equity offering with gross proceeds of at least
$75.0 million or in certain other circumstances specified in the indenture for
the Senior Notes, provided, however, that at least two-thirds of the principal
amount of the Senior Notes originally issued remains outstanding after each such
redemption. Pursuant to the covenants in the offering, the Company has filed an
S-4 registration statement with the Securities Exchange Commission to exchange
registered senior notes, with the same terms and conditions as the Senior Notes,
for the Senior Notes.
    
 
NOTE 3.  RELATED PARTY TRANSACTIONS
 
   
     During 1997, additional shareholder loans of $7.5 million, $3.9 million and
$2.2 million were received from GTS-Hermes, NMBS and Swed Carrier, respectively.
All shareholder loans outstanding were converted into equity prior to September
30, 1997 (See Note 1, "Financial Presentation and Disclosures").
    
 
NOTE 4.  SUBSEQUENT EVENTS
 
   
     Subsequent to September 30, 1997, the Company 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
$98.0 million. The commitments have expected lease terms of three to twenty
years with options for renewal rights of five additional years. As of September
30, 1997, the Company made deposits of approximately $6.8 million related to the
above leases.

ITEM 22.  UNDERTAKINGS.
 
   
     The undersigned registrant hereby undertakes:
    
 
   
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
    
 
   
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;
    
 
   
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.
    
 
   
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
    
 
   
     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section
     do not apply if the registration statement is on Form S-3, Form S-8 or Form
     F-3, and the information required to be included in a post-effective
     amendment by those paragraphs is contained in periodic reports filed with
     or furnished to the Commission by the registrant pursuant to section 13 or
     section 15(d) of the Securities Exchange Act of 1934 that are incorporated
     by reference in the registration statement.
    
 
   
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
    
 
   
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
    
 
   
          (4) If the registrant is a foreign private issuer, to file a
     post-effective amendment to the registration statement to include any
     financial statements required by sec.210.3-19 of this chapter at the start
     of any delayed offering or throughout a continuous offering. Financial
     statements and information otherwise required by Section 10(a)(3) of the
     Act need not be furnished, provided that the registrant includes in the
     prospectus, by means of a post-effective amendment, financial statements
     required pursuant to this paragraph(a)(4) and other information necessary
     to ensure that all other information in the prospectus is at least as
     current as the date of those financial statements. Notwithstanding the
     foregoing, with respect to registration statements on Form F-3, a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or sec.210.3-19 of
     this chapter if such financial statements and information are contained in
     periodic reports filed with or furnished to the Commission by the
     registrant pursuant to section 13 or section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Form F-3.

     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.
 
     The undersigned registrant hereby undertakes that every prospectus (i) that
is filed pursuant to the immediately preceding paragraph, or (ii) that purports
to meet the requirements of section 10(a)(3) of the Securities Act and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     The undersigned registrant hereby undertakes: (i) to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means; and (ii) to arrange or provide for a facility in the
U.S. for the purpose of responding to such requests. The undertaking in
subparagraph (i) above includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20 "Indemnification
of Directors and Officers," above, or otherwise, the Registrant has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the paying by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification is against public policy
as expressed in the Act and will be governed by the final adjudication of such
issue.

Ladies and Gentlemen:

         We have acted as special United States counsel to Hermes Europe Railtel
B.V., a Netherlands company (the "Company"), in connection with the filing by
the Company under the Securities Act of 1933, as amended (the "Act") of a
registration statement on Form S-4 (the "Registration Statement") with the
United States Securities and Exchange Commission (the "Commission"). Pursuant to
the Registration Statement, up to U.S.$265,000,000 aggregate principal amount of
the Company's outstanding 11 1/2% Senior Notes due 2007 (the "Outstanding
Notes") are exchangeable for up to a like principal amount of the Company's 
11 1/2% Senior Notes due 2007 (the "Exchange Notes"). The Outstanding Notes 
were, and the Exchange Notes will be, issued pursuant to an indenture (the
"Indenture") dated as of August 19, 1997 among the Company, Global TeleSystems
Group, Inc. and The Bank of New York, as trustee (the "Trustee"), registrar,
paying agent and transfer agent. The Exchange Notes and the Outstanding Notes
are collectively referred to herein as the "Notes."

         In our capacity as special United States counsel to the Company, we
have examined the Registration Statement, the Indenture filed as Exhibit 4.3 to
the Registration Statement, the Outstanding Notes, a form of the Exchange Notes
contained in such Indenture and originals or copies certified or otherwise
identified to our satisfaction of such documents as we have deemed necessary or
appropriate to enable us to render the opinions expressed below.

         Based upon the foregoing, it is our opinion that when the Exchange
Notes are exchanged for the Outstanding Notes as contemplated in the
Registration Statement, assuming they have been duly authorized, executed,
issued and delivered by the Company under the laws of the Netherlands and have
been duly authenticated by the Trustee, the Notes will constitute the legal,
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms, except as enforcement thereof may be limited by
bankruptcy, insolvency (including, without limitation, all laws relating to
fraudulent

transfers), reorganization, moratorium and other similar laws relating to or
affecting enforcement of creditors' rights generally and by possible judicial
action giving effect to foreign governmental actions or foreign laws affecting
creditors' rights and except as enforcement thereof is subject to general
principles of equity (regardless of whether such enforcement may be sought in a
proceeding in equity or law).

         The opinion set forth in the above paragraph is qualified to the extent
that we have assumed the due authorization, execution and delivery of the
Indenture by the Trustee and the Company.

         We are attorneys admitted to practice law in the State of New York and
we do not express herein any opinion as to any matters governed by or involving
conclusions under the laws of any other jurisdiction other than the federal law
of the United States of America. In rendering the opinion expressed herein, we
have, with your approval, relied without independent investigation as to all
matters governed by or involving conclusions under the law of the Netherlands
upon the opinion (including the qualifications, assumptions and limitations
expressed therein) of Loeff Claeys Verbeke, Dutch counsel for the Company, of
even date herewith, a copy of which is attached hereto.

         This opinion may be delivered to Loeff Claeys Verbeke which may rely on
this opinion to the same extent as if such opinion were addressed to it.

         We hereby consent to the use of this opinion as Exhibit 5.1 to the
Registration Statement and to the use of our name under the caption "Legal
Matters" contained in the prospectus which is included in the Registration
Statement.


                                                   Very truly yours,


                                                  [Shearman & Sterling]

WHEREAS:

a.          in 1990, HIT Rail was incorporated by the National Railways as
            hereinafter defined to carry out telecommunications engineering
            activities in order to construct and exploit a data communications
            network for railway traffic;


b.          HIT Rail established the Company on July 6, 1993 to conduct the
            Business as defined in Article 3 of this Agreement;

c.          GTS Hermes acquired a fifty percent interest in the Company in 1994
            and HIT Rail and GTS Hermes presently own the entire issued share
            capital of the Company;

d.          the Company has in January 1997 launched a capital restructuring
            plan allowing for direct participation of the National Railways and
            of selected other participants in the Company's capital and for the
            issue of additional shares to the existing shareholders of the
            Company;

e.          it is the intention of HIT Rail to transfer its shares in the
            Company to the HIT Rail Shareholders in proportion to their current
            indirect shareholding in the Company and as a result the HIT Rail

                    It is the intention of the Parties to maximize distributions

                                                                          - 17 -

                    not be less than four (4) members.

          (c)       The Board of Supervisory Directors shall designate its
                    Chairman and Vice Chairman and the Shareholders shall
                    procure that the Board of Supervisory Directors appoints as
                    Chairman and Vice Chairman the persons so designated. The
                    Chairman shall prepare an agenda for the meetings of the
                    Board of Supervisory Directors, without prejudice to the
                    right of the members to put up for discussion at meetings
                    issues other than those set out in the agenda. The Chairman,
                    or in his absence the Vice Chairman, shall preside the
                    meetings.

          (d)       Each Participating Shareholder who holds an interest of at
                    least 6.8% in the issued capital of the Company shall be
                    entitled to make a binding nomination for the appointment of
                    one (1) Supervisory Director, and, the other Participating
                    Shareholders together to the extent each holds less than
                    6.8% shall be entitled by rotation to make a binding
                    nomination for the appointment for 2 years of one (1)
                    Supervisory Director, provided that, so long as HIT Rail is
                    the legal owner of at least one (1) Share. HIT Rail shall be
                    entitled to nominate at least one (1) Supervisory Director.
                    If the Participating Shareholders together holding less than
                    6.8% cannot agree on the person to be appointed, any one of
                    them may refer the decision to appoint a new member to the
                    Supervisory Board whose decision shall be binding on the
                    Participating Shareholders. So long as GTS Hermes is the
                    legal owner of 50% of the Shares, GTS Hermes shall have the
                    right to make a binding nomination for appointment of such
                    number of members of the Board of Supervisory Directors as
                    matches the number of members appointed by the other
                    Shareholders. If GTS Hermes is the legal owner of two-thirds
                    (2/3) or more of the Shares, GTS Hermes shall have the right
                    to make a binding nomination for appointment of such number
                    of members to the Board of Supervisory Directors equal to
                    one member more than appointed pursuant to the nominations
                    by all the other Shareholders. The percentage of 6.8%
                    reflects the estimated increase of the interest of NMBS in
                    the Company after the HIT Rail Shareholders have become
                    direct shareholders of the Company as mentioned in the
                    "WHEREAS" clause under e., and consequently, such percentage
                    is subject to change if the issued capital of the Company as
                    set forth in Article 2, is increased.

                    meeting shall be provided by the Chairman no less than two
                    (2) weeks in advance. The quorum for meetings of the Board
                    of Supervisory Directors validly convened shall be a simple
                    majority of the members of the Board of Supervisory
                    Directors. If the quorum is not represented in such meeting,
                    a second meeting of the Board of Supervisory Directors will
                    be called on a date which is at least 5 business days and
                    not more than 4 weeks after the date of the first meeting.
                    In such second meeting, resolutions on the subjects put
                    before the first meeting can be adopted by a majority of the
                    votes cast irrespective of the number of Supervisory
                    Directors represented at such second meeting. Each
                    Supervisory Director may designate any other Supervisory
                    Director to serve as his attorney-in-fact at any such
                    meeting. The Company shall bear the reasonable costs and
                    expenses of the attendance of the members at the meetings of
                    the Board of Supervisory Directors.

          (f)       At each of its regular meetings, the Board of Supervisory
                    Directors shall determine the time and place of the Board's
                    next regular meeting. The Chairman may, on his own
                    initiative or at the request of any other member, call
                    non-regular meetings of the Board of Supervisory Directors.

          (g)       The Board of Supervisory Directors may also convene and/or
                    take action by telephone or video-conferencing, provided
                    that the quorum set out in paragraph (e) above is present
                    thereat. The Board may also take action by unanimous written
                    consent.

          (h)       Subject to the Articles of Association, issues arising at

              Shareholder shall be obliged to transfer such Shares (or the
              rights to be allotted Shares) to such third party who shall be
              deemed to be acceptable to the other Shareholders. The purchase
              price of any transferred Shares shall be determined pursuant to

         cooperate in the preparation and delivery of the notification or
         information.

12.2     Publicity

         For the duration of this Agreement, any formal press, public
         announcement, news release or other form of major publicity relating to
         this Agreement or any of its terms shall be made only after prior
         consultation between the Parties and if the substantive content is
         mutually agreed upon. No party shall unreasonably withhold or delay its
         consent to any formal press, public announcement, news release,
         filings, or other form of major publicity relating to the existence of
         this Agreement or its terms, if such is required by the laws of any
         jurisdiction governing any of the Parties or in connection with the
         procurement of capital.

12.3     Severability

         Each and every obligation under this Agreement shall be treated as a
         separate obligation and shall be severally enforceable as such and in

         unenforceable in whole or in part such



<PAGE>   27
                                                                          - 27 -

        part or parts as are unenforceable shall be deemed deleted from this
        Agreement and any such deletion shall not affect the enforceability of
        the remainder of this Agreement.

12.4    Force Majeure

        The failure or delay of any Shareholder (the "Affected Shareholder") to
        perform any obligation under this Agreement or the Company being unable
        to conduct its business solely by reason of acts of civil or military
        authority, civil disturbance, war, strikes or other labour disputes (by
        employees of any third party) or disturbances, fire, or laws,
        regulations, acts, or orders of any governmental agency or official
        thereof, other catastrophes, or any other circumstances beyond its
        reasonable control ("Force Majeure") shall not be deemed to be a breach
        of this Agreement so long as the Affected Shareholder or its Affiliated
        Company shall not have contributed to such Force Majeure, shall have
        used its best reasonable efforts to avoid such Force Majeure or to
        ameliorate its effects, and shall continue to take all actions within
        its power to comply to the extent possible with the terms of this
        Agreement. In the event of any such failure or delay, performance of the
        obligations shall be deferred until the Force Majeure ceases to affect
        the performance of obligations hereunder, provided that if the Force
        Majeure affects the performance of a material obligation and has not
        ceased within nine (9) months, any Affected Shareholder may withdraw as
        a Party to this Agreement.

12.5    Entire Agreement

        This Agreement and the agreements to be entered into pursuant to it
        supersede all prior agreements among the Parties with respect to the
        subject matter hereof and contain the entire agreement among the Parties
        with respect to the subject matter hereof, including the Annexes. Each
        party confirms to each of the others that it is not relying on any
        representation, warranty, or commitment of any kind save as set out in
        or explicitly contemplated by this Agreement and the Annexes and, for
        the avoidance of doubt, the Parties (other than the Company) acknowledge
        that their respective Shareholders are not parties hereto and are in no
        way whatsoever bound by, and will not be held to by the Company, any
        Shareholder or any of their



<PAGE>   28
                                                                          - 28 -

        respective Affiliated Companies, any of the terms hereof.

12.6    Amendment

        This Agreement may not be amended, supplemented, or discharged, and no
        provision may be modified or waived, except as expressly provided in
        this Agreement or by an instrument in writing signed by such a number of
        Parties together holding at least (eighty-five) (85)% of the voting
        shares in the capital of the Company, in which case the amended
        Agreement shall be effective in respect of all Parties to the Agreement
        as of the date of the signed instrument, notwithstanding the fact that
        any one Party has not approved such amendment. No waiver of any
        provision hereof by any Party shall be deemed a waiver by or in favour
        of any other Party, nor shall any such waiver by any Party be deemed a
        continuing waiver of any matter or a waiver of any other matter by such
        Party. No allowance of time or other indulgence shall constitute a
        waiver or preclude the subsequent assertion or enforcement of the right
        or remedy concerned or any other right or remedy. No exercise of any
        right or remedy shall be deemed to imply a waiver of, or prevent the
        subsequent assertion or exercise of, any other right or remedy in
        respect of the same or any other matter. No amendment, modification,
        supplement, discharge, or waiver hereof or hereunder shall require the
        consent of any person not a Party to this Agreement except as required
        by law.

12.7    Variations in Terms and Pronouns

        All terms, pronouns, and any variations thereof, shall be deemed to
        refer to the masculine, feminine, neuter, singular, or plural as the
        identify of the person or persons or entity or entities require.

12.8    Headings

        All captions or headings contained in this Agreement are for convenience
        or the Parties only and shall not affect the interpretation of any
        provision of this Agreement.

Dear Sir:

      I hereby inform you that, pursuant to the ministerial decision dated
3/29/1996 for the trial projects mentioned in your aforementioned letter, IBPT
can allow an exception to Article 92, ss. 1 of the law dated March 21st
pertaining to reform of certain semi-public corporations.

      The projects have been registered under the number

                                  NRS/96/4002/1

      As stated in the declaration, they comply with specific criteria, namely:

- -     they will be carried out on a clearly defined layout, geographically
      limited from Brussels to Essen via Anvers;
- -     the duration is limited from 8/15 to 12/15/96 inclusive;
- -     there is no commercial development;
- -     no communication for the public in general is possible.

      The competent supervisory department has been informed of this letter.

      Finally, I hope that the trials will have the outcome anticipated. Future
projects may always be certified in the same way.

                                          Sincerely,

Class 3, across which telecommunication services are offered to the public by it

with Sections 44 through 48 TKG and the frequency regulations based
thereupon. Such frequency assignments are an integral part of this license. The
right to further specify the object of the license is reserved if radio
frequencies are used for services within the framework of License Class 3.

mobile phone services or satellite phone services for the public
(Section 6 Para. 2 No. 1 Items a) and b) TKG), or to operate

the right to use, at no charge, public traffic routes for telecommunication
lines (Section 3 No. 20 TKG) which it needs to exercise the licensed rights, in
accordance with Sections 50 through 58 TKG, insofar as such use does not
perpetually restrict the established purpose of the traffic route.


3 INCIDENTAL PROVISIONS

3.1 Changes in the Commercial Register shall be reported to the licensor without
delay, with attachment of a certified excerpt from the Commercial Register. The
information is needed to allow an evaluation of the continued presence of the
license preconditions pursuant to Section 8 Para. 3 Clause 2 No. 2 TKG and to
ensure compliance with the obligations upon a change in the licensee and/or a
change of ownership status pursuant to Section 9 TKG.

representative, to submit the documents named in Section 87 Para. 2 TKG,
and to issue the statement pursuant to Section 87 Para. 2 Clause 2 TKG,
all prior to the initial commissioning.


4 REMARKS

4.1 As long as transmission capacity is provided by the licensee's
telecommunications installation exclusively in the manner depicted under Points
5.1 through 5.3 of the license application and no end-customers are connected to
the telecommunications installation, no technical precautions shall be
instituted to apply monitoring measures pursuant to Section 88 of the
Telecommunications Act, until further notice. Such precautions are necessary as
soon as end-customers are connected to the telecommunications installation. They
can similarly become necessary if telecommunication services other than those
indicated in the license application are provided by way of the
telecommunications installation.
<PAGE>   4
The licensee is urged to comply with this provision in the planning and
execution of its telecommunications installation; noncompliance can result in
revocation of the license pursuant to Section 15 of the Telecommunications Act.

The fundamental statutory obligations from the provisions of Sections 100a
and 100b of the Code of Criminal Procedure, the Law on Restricting Mail, Postal,
and Communications Confidentiality, and Sections 39 through 43 of the
External Economic Relations Act are
unaffected by this license provision.

4.2 Granting of the license is subject to a fee pursuant to Section 16
Para. 1 Clause 1 TKG. The fee is established through a separate
ruling, based on the legal regulation to be issued pursuant to
Section 16 Para. 1 Clause 2 TKG.

4.3 Any assignments of frequencies to operate transmission paths in the form of
radio links are subject to a fee and to contributions pursuant to Section 48 TKG
and the legal regulations issued on the basis of this provision. Frequency
assignment fees and frequency usage contributions are established through
separate rulings. Changes in assignment and new assignments of frequencies are
effected through independent administrative acts.

4.4 Under Section 8 Para. 2 Clause 2 TKG, further incidental provisions
can be added to this license even after it is granted.

4.5 It is pointed out that in addition to this license, the special provisions
of the TKG must be complied with.


                         INSTRUCTIONS ON RIGHT OF APPEAL

Action can be brought against this administrative act within one month of
publication before the Cologne Administrative Court, Appellhofplatz, 50667

9.    EGT SECURITY MEASURES

      EGT's standard security measures are detailed below. More in depth
      measures may be implemented by mutual agreement and would be subject to
      separate negotiation.

9.1   Equipment Rooms

      EGT equipment rooms will be built out of materials designed to provide a
      minimal protection of 2 hours against fire coming from the adjoining
      spaces both internal or external. All holes in walls, floor and ceiling of
      the room, i.e. for pipes, wires, etc. are filled with fire proof materials
      and ducts are equipped with fire barriers.

      Normally windows are not fitted but where they are special protection
      measures are taken.

9.2   Doors

      Doors will be made of 1 hour fire proof material and will be equipped with
      panic bars. Door entry alarms will be fitted which will be remotely
      monitored by the EGT Network Management Centre.


                                      -20-
<PAGE>   23

9.3   Locks

      Doors will be fitted with a security lock for which keys cannot be
      reproduced without the agreement of EGT. Access control and management of
      key distribution will be implemented.

9.4   Fire Extinguishing System

      Where Sites are not located close to a 24 hours a day, 7 days a week basis
      security centre allowing rapid intervention of less than 3 minutes in case
      of fire detection, such Sites will be protected by a halon free
      extinguishing system (type Argonite, Inergen or other). This system will
      be connected to a fire detection system which operates automatically after
      a predetermined time in case of fire detection. The system will generate
      as a minimum the following alarms which will be remotely monitored by the
      EGT Network Management Centre:

      o     Fault

      o     Operation

9.5   Fire Extinguishers

      A minimum of two CO2 fire extinguishers will be installed in all equipment
      rooms.

9.6   Lightning Protection

      Buildings will be equipped with an appropriate number of lightning
      conductors. External inputs to the building such as, cables, pipes, power
      supplies, ducts, etc. will also be protected against lightning strikes

9.7   HVAC

      The temperature and humidity of equipment rooms is controlled and
      maintained between the following parameters:

      o     Temperature: 20 (degree)C +/ 2 (degree)C

      o     Humidity: 50% +/ 10%


                                      -21-
<PAGE>   24

      The system will generate as a minimum the following alarms which will be
      remotely monitored by the EGT Network Management Centre:

      o     Fault

      o     Shutdown

9.8   Signs

      Signs will be fitted in accordance with relevant Health and Safety
      Regulations and will include the evacuation procedure and the list of
      important numbers such as police, fire brigade etc.

9.9   Electrical Network

      A simplified diagram showing the electrical path and location of equipment
      from the public power supply network inlet to all equipment will be
      available and maintained.

9.10  Inspection

      The following will be inspected at least annually to ensure they are fully
      functional and safe:

      o     Fire Extinguishing System

      o     Fire extinguishers

      o     Power and electrical systems

      o     HVAC system

      o     Lightning Protection

            accordance with Schedule 4 provided there is no deterioration to the
            Services.

      5.2   EGT shall use its reasonable endeavours to ensure that the Fibres
            and Interface Equipment are fully prepared to be connected to the
            User's Equipment or the User's fibre by the Ready for Testing dates
            set. Once the Fibres and Interface Equipment are so prepared the
            User shall carry out the connection.

      5.3   EGT and the User shall each carry out the Acceptance Tests
            designated as their responsibility in the Technical Definition and
            exchange test results. Each party shall complete their Acceptance

      5.4   On satisfactory completion of the Acceptance, EGT and the User shall
            each sign a Certificate of Readiness indicating the Provision Date.

      5.5   If an Acceptance Test ("the Initial Acceptance Test") is not
            satisfactorily completed, the parties agree to co-operate in order
            to identify the cause of the failure of the Acceptance Test. EGT and
            the User shall use best efforts to resolve the problem. Once the
            problem has been resolved, the parties shall carry out the
            Acceptance Tests ("the Further Acceptance Tests") in accordance with
            the provisions of the Annex. Unless the failure of the Initial
            Acceptance Test is due to any negligent act, omission or breach of
            contract by the User the costs of Further Acceptance Tests will be
            borne by EGT.

      5.6   If the cause of the failure of the Acceptance Tests has not been
            identified within 5 Business Days of the date upon which the Initial
            Acceptance Test failed to be


                                      -33-
<PAGE>   36

                             CONFIDENTIAL TREATMENT

            satisfactorily completed EGT shall use reasonable endeavors to
            identify suitable alternative fibres (which shall themselves be
            subject to Acceptance Testing under this Clause); or an alternative
            solution that will meet the Acceptance Tests.

6.    PAYMENTS

      6.1   In consideration of EGT providing the Services, and the other
            obligations assumed by EGT pursuant to the Agreement, the User
            shall at the due dates pay Usage Payments (less any payments due
            under Clauses 6, 8 or 9 of Schedule 1) to EGT.

      6.2   EGT will invoice the User for Usage Payment Quarterly in advance.

      6.3   The User shall pay the said invoices within 45 days of the date of
            the said invoices.

      6.4   The Usage Payment will be subject to annual review and uplift on
            each anniversary of the Provision Date using the formula below:

            new Usage Payment = last Usage Payment x (## MATERIAL OMITTED AND
            SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## +
            fractional change in RPI since last annual review - ## MATERIAL
            OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
            TREATMENT ##)

            limited to a maximum uplift of ## MATERIAL OMITTED AND SEPARATELY
            FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## for any one
            annual period.

            For the purposes of this calculation the new RPI used shall be the
            one published most recently prior to the relevant anniversary of the
            Provision Date.

            All RPI Uplifts shall be calculated on this basis.

      6.5   If the User fails to pay for the Services on or before the due date,
            EGT may without prejudice to any rights or remedies it may have:

            6.5.1 if payment in full is not made within 30 days of due date
                  cancel or suspend any further provision to the User of the
                  Services;

            6.5.2 charge the User interest on the outstanding amounts (both
                  before and after any judgment) at the rate of ## MATERIAL
                  OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
                  TREATMENT ## above the National Westminster Bank Plc base rate
                  per annum calculated on a daily basis from the date the
                  payment was due until the total sum has been paid.

      6.6   The Usage Payment is expressed exclusive of VAT and any VAT
            chargeable shall be paid in addition by the User.

      6.7   Loss of Service Payments and payments under Clause 6 of Schedule 1
            shall appear as a deduction from the Usage Payment otherwise payable
            on User's account for the Quarter following the Quarter in which the
            Loss of Service Payment arose.

            (provided that the time of performance is not of the essence).

      7.5   Termination of the Agreement shall be without prejudice to the
            rights by the party accrued prior to termination including any right
            to payment of any sum and any right to sue in respect of any

9.    CONFIDENTIALITY AND INTELLECTUAL PROPERTY

      9.1   Each Party agrees to keep confidential all Confidential Information
            of the other Party and to use the same exclusively for the purposes
            of or as contemplated by the Agreement and to disclose the same only
            to those of its employees, Group companies, agents and
            sub-contractors pursuant to the Agreement (if any) to whom and to
            the extent that such disclosure is reasonably necessary for the
            purposes of the Agreement.

      9.2   The obligations and restrictions contained in this Clause 9 shall
            not apply to information:

            9.2.1 which is now or subsequently becomes available to the public
                  otherwise than by breach of the Agreement by the receiving
                  Party;

            9.2.2 which the receiving Party can prove by documentary evidence
                  was already in the receiving Party's possession and at its
                  free disposal prior to obtaining the same directly or
                  indirectly from the other Party;

            9.2.3 which is subsequently disclosed to the receiving Party free of
                  restrictions on disclosure and use by a third party not acting
                  on behalf of the other Party or directly or indirectly bound
                  to the other Party by obligations of confidentiality or
                  non-use in relation to such information; or

            9.2.4 which the receiving Party is required by any reason of law to
                  disclose.

      9.3   For the avoidance of doubt nothing in this Clause 9 shall be
            interpreted as preventing either Party making full and unrestricted
            use of its knowledge and expertise pertaining generally to the
            industry of the other Party.

      9.4   All intellectual property relating to the subject matter of this

            EGT, its officers or employees shall vest in EGT.

      9.5   The User acknowledges that it shall have no licence, right, title or
            interest in or to any intellectual property relating to the Network
            or Services.

            both the Parties so decide the provision of Clause 10.2 shall apply.

      10.2  If both Parties agree to refer an issue to an Expert and the Parties
            fail to nominate or agree such Expert within 10 days, then the

            10.2.1 in the case of a dispute as to the interpretation or
                   construction of this Agreement, by the President or other

                   appropriate in the circumstances.

      10.3  Each of the Parties shall be entitled to provide the Expert with
            such information and such written representation as may be necessary
            to assist in the determination of the dispute in question provided

            the date of the referral.

      10.4  The Expert shall be entitled to seek expert evidence at his

            final and binding on both Parties.

            circumstances of Force Majeure.

                  inaccuracy; or

            3.5.2 it is found that the deterioration in the Service which is the
                  subject of the Fault Notice has been caused by the act or
                  omission of the User or its Customers contrary to the notified
                  requirements of EGT or to the ordinary and proper standards of
                  usage applicable to the Designated Purpose; or

            3.5.3 it is found that the deterioration in the Service which is the
                  subject of the Fault Notice is not due to a Disruption;

            (any such Fault Notice hereinafter referred to as a "Defective
            Notice") then:-

            3.5.4 immediately on becoming aware of a matter referred to in

<PAGE>   49

            3.5.6 the Defective Notice shall cease to have effect and all
                  provisions in respect of Time Limits for the completion of
                  Corrective Maintenance and the provisions in respect of the
                  Loss of Service Payments in the Agreement shall cease to have
                  effect in respect of the Defective Notice but without
                  prejudice to other relevant provisions in the Agreement; and

            3.5.7 in the event that:

                3.5.7.1 The Defective Notice is in respect of a Disruption;
                        and

                3.5.7.2 the User continues to require EGT to carry out
                        Corrective Maintenance hereunder;

                  the User shall issue a further Fault Notice which shall
                  validly contain the information referred to in Clause 3.3
                  hereof.

      3.6   Subject to Clause 5.1.4 the User shall provide assistance to carry
            out the above Corrective Maintenance in which case the User shall
            act reasonably and without delay in determining whether it will
            agree to such a request and shall not delay in notifying EGT of its
            decision. For the avoidance of doubt the User will not be requested
            to provide on-site assistance.

      3.7   For the avoidance of doubt the User shall be responsible for all
            corrective maintenance, preventative maintenance and all other works
            or tests of whatsoever kind to the User's Equipment for the purpose
            of using the Services but shall not carry out Corrective Maintenance
            or Preventative Maintenance.

      3.8   It is recognised by the User that in certain circumstances EGT may
            require the User to power down the lasers and otherwise make safe
            the User's Equipment to allow work to take place on the Network or
            Interface Equipments; the User will comply with all such requests
            and will leave the User's Equipment in such condition until
            authorised by EGT's Fault Control Point that it may be restored to
            its operational condition. Such requirements will be considered
            Corrective Maintenance or Preventative Maintenance as appropriate.

4     DUTIES OF EGT

      4.1   EGT shall supply the User with such accurate records of the Network
            and interface Equipment as the User may reasonably request in order

                  Preventative Maintenance; and

            4.3.3 all works in respect of such Preventative Maintenance shall be
                  carried out by EGT as Planned Work in accordance with Clause
                  6.

      4.4   EGT shall carry out Corrective Maintenance to the Network and
            Interface Equipment upon:-

            4.4.1 receipt of a Fault Notice in accordance with Clause 3.2; such

<PAGE>   52

            5.6.2 any period wherein EGT was unable to perform its obligations
                  contained in this Schedule due to an act or omission of the
                  User (which shall include any delay by the User in performing

            follows:-

            6.1.1 for Planned Work to the Network or Interface Equipments not
                  involving an interruption to the Services EGT shall give three
                  working days notice of the commencement of the work;

            6.1.2 should it be necessary for Planned Work to involve
                  interruption to the Services EGT shall give the User as much
                  notice as it is reasonably able to give but in any event not
                  less than 30 days notice of the commencement of such Planned
                  Work and the User shall afford all assistance to EGT to enable
                  the work to commence on the planned date and for it to be
                  completed efficiently;

            6.1.3 Planned Work undertaken in order to complete a Permanent
                  Repair under Clause 5.3 hereof shall be carried out at the
                  time agreed by the Parties in accordance with Clause 5.3
                  hereof.

      6.2   For the avoidance of doubt, a Planned Outage which lasts longer than

            remainder of its duration.

      6.3   EGT shall not arrange for Planned Outages on both Routes at the same
            time under any circumstances; subsequent Planned Outages shall be at
            least 3 working days apart. Furthermore, EGT shall use reasonable
            endeavours not to implement any Planned Outage when the User
            notifies EGT that there is or is likely to be an isolation of one of
            the User's nodes (bearing in mind the impact on EGT's Network of
            carrying out the works against the impact of delaying the works
            until the outage on the User's Network is repaired).

      6.4   For the purpose of calculating time elapsed during a Planned Outage,
            Planned Work shall be deemed to have commenced at the time agreed
            between the parties under Clause 6.1.3 hereof and ended on issue of
            a notice under Clause 7.1.2 hereof.

17.   Exoneration

17.1. In this Agreement, "Event of Force Majeure" means any abnormal or
      overwhelming circumstances which (despite prudent management and
      operations) are beyond the control of the party affected and which prevent
      that party from fulfilling its obligations under this Agreement in a
      timely manner or in compliance with this Agreement, including any storm,
      tempest, fire, flood, snow, water, sabotage, riot, rebellion or government
      action (save to the extent that the government is acting as shareholder in
      the party in question) or industrial disputes by any person other than
      employees of the party claiming the benefit of Force Majeure or its
      Affiliates, but specifically excluding failures or delays on the part of
      the defaulting party, arising out of:

      (a)   any failure or delay on the part of any defaulting party or any
            sub-contractor engaged by the defaulting party which is not itself
            caused by Force Majeure; or

      (b)   shortages of fuel, supplies or services which are not themselves
            caused by Force Majeure.

                                                                   Page 19 of 42

17.2  A party affected by an Event of Force Majeure or strike action by its
      employees shall use its best endeavours to minimise its effects.

17.3  No party shall be responsible for any failure to fulfil its obligations
      under this Agreement if, and only to the extent that such failure shall be
      caused by an Event of Force Majeure or strike action by its employees
      which makes in impossible or impractical for than party to comply with
      such obligations.

17.4  If a party considers than any Event of force Majeure has arisen or may
      arise, or that strike action by its employees is planned it shall
      immediately notify the other Party of its reasons and likely extent of the
      delay and the parties shall endeavour to find a means of avoiding the
      delay or disruption.

      calculated in accordance with Schedule 3 and the Participating Railway

      Majeure.

            details of which have been communicated to the Participating Railway
            in writing;


                                                                        38 of 42

      (b)   comply with all regulations and or laws in every country over which
            the HER Links run which concern the provision of services by the
            Participating Railway; and

      (c)   restrict its use of the Services to the application described in
            Paragraph 2.1.

7.3   The Participating Railway shall indemnify HER and hold it harmless against
      all actions, proceedings, claims, demands or costs howsoever arising out
      of any breach by the Participating Railway of any provision of this
      Schedule or any infringement of third party intellectual property rights
      arising from the carriage of signals introduced into the HER Network by
      the Participating Railway or of any breach by the Participating Railway of
      any law, regulation, licence approval authorisation applicable to the
      provision or use of Services.

7.4   The Participating Railway and HER agree that, should the Participating
      Railway use the Services to provide a commercial service to a third parry
      in violation of Paragraph 7.2(c), the appropriate measure of the damage
      suffered by HER as result of that breach is an amount equal to the total
      revenues derived by the Participating Railway from the provision of such
      service.

8.    Liability

8.1   Provided that HER is able to offer diverse routing along any HER Link, HER
      shall pay Service Credits to the Participating Railway for any Loss of
      Service exceeding the Thresholds on that HER Link, arising due to the
      gross negligence of HER. The aggregate Service Credits payable in any ##
      MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
      TREATMENT ## period shall not exceed the annual contract value of the
      Fibre Agreement

      For the avoidance of doubt, HER shall not be liable to the Participating
      Railway for any delay in the implementation of the Services or any part
      thereof.

8.2   HER shall in no event be liable to the Participating Railway for any loss
      of revenue, loss of profit, loss of contract or loss of goodwill, or any
      indirect or other consequential loss, howsoever caused, arising under or
      in connection with this Schedule.

8.3   The provisions of this paragraph will survive termination of this
      Schedule.


                                                                        39 of 42

9.    Right of Rescission

9.1   If, despite using best endeavours, HER is unable to obtain or maintain any
      licences required by HER in any country to establish or operate the HER
      Network or any HER Link or to provide transmission services, or if they
      are revoked, or if HER's provision of transmission services is challenged
      in any country over which the HER Links run by a formal written
      communication from any relevant national regulatory authority or Court,
      HER shall not face any claim for loss damage or compensation from the
      Participating Railway;

10.   Termination

10.1  Notwithstanding clauses 21 and 22 of this Agreement, if the Participating
      Railway commits a material breach of its obligations under this Schedule
      which is capable of remedy, HER shall serve notice in writing on the
      Participating Railway, requiring the Participating Railway to cure the
      breach:

      (a)   within two months if it is a breach of the proviso to paragraph 2.1
            of this Schedule or a breach of paragraph 7.1 or 7.2 of this
            Schedule or if the Participating Railway's use of the Services
            damages or disrupts the HER Network; or

      (b)   within six months for any other material breach.

10.2  on receipt of the notice in paragraph 10.1 the Participating Railway shall
      with all reasonable diligence take such steps as shall be reasonable and
      necessary to remedy the breach and shall keep HER informed of the progress
      being made.

10.3  Without prejudice to paragraph 10.4. in the event that the Participating
      Railway disputes that there is a material breach then the parties will
      appoint a Project Mediator in accordance with Schedule 4 paragraphs 5 to
      10 to resolve the issue within the cure period mentioned above.

10.4  If the breach is not cured within the periods stated above and no solution
      has been found under paragraph 10.3 HER shall be entitled to terminate the
      Services and clause 22.2(b) shall apply.

10.5  For the avoidance of doubt. In the event and for the period that HER is
      using the Railway Fibre after the Participating Railway has terminated
      this Agreement, as provided for by sub-clause 22.2(a), HER shall continue
      to provide the Services to the Participating Railway.


                                                                        40 of 42

11.   Assignment

      The Participating Railway may not assign or sub-contract its rights or
      obligations under this Service Agreement without the prior written consent
      of HER.

3 - SPECIFICATIONS FOR FIBRES LEASED BY HERMES

      3.1.  NEW CABLES BUILT BY THE RAILWAYS:

            In the case of new cables built by the RAILWAYS, it is recommended
            that, as a minimum, specifications for cables as defined in chapter
            2 (including for the cable splices and connectors) are applicable.
            The minimum cable specification required for the HERMES Network is
            as defined in 3.2. Existing cables

      3.2.  EXISTING CABLES:

            In the case of existing cables owned by the RAILWAYS, the
            specifications in Chapter 2 must be met with respect to the
            following optical properties at 1550 nm : Attenuation, Chromatic
            Dispersion, and Polarization Mode Dispersion. The specifications for
            the cable splices and connectors in chapter 2 are also applicable.

4 - CABLE TESTING

      4.1.  INTRODUCTION:

            This chapter describes tests related to cable. For existing and new
            leased cables this chapter provides advice to the RAILWAYS on test
            procedures to be applied.

            It should be noted that all measurements must be carried out by
            personnel who are skilled and experienced in the use of test
            equipment involved and have proven ability to carry out these
            measurements in a field environment.

      4.2.  GENERALITIES:

            The purpose of the testing during and alter installation is:

            - To check that cable laying operation did not adversely affect the
            attenuation of the optical fibres, compared to that recorded during
            factor acceptance tests.

            - To check that splices on the optical fibres are satisfactory, and
            do not adversely affect the attenuation values.

            - To establish validity of the link by measuring its performances
            from end to end.

            Measurements made on optical fibres refer to CCITT recommendation G
            652 for single mode fibers and C 653 for dispersion shifted fibers.

            The characteristics of optical fibre transmission mostly concern
            transmission attenuation and determines the ability to transmit data
            across the link. It can also reveal mechanical strains that may
            cause later fibre breakage.

            There are two types of attenuation measurements:

            - Optical power attenuation measurement : measuring the power
            launched into the fibre as well as that restored at the receiver
            input enables accurate calculation of the complete link attenuation.

                  Att (dB) = Tx P (dB) - R x P (dB)

            - Back scattering measurement: Measuring the light scattered into
            the fibre, to draw up the attenuation curve. This measurement shows
            any variation in attenuation, and allows the location to be
            determined.

      4.3.  TESTS TO BE PERFORMED ON SITE FOR NEW CABLES:

            The tests described in this section are recommended to the RAILWAYS
            for new cables leased by HERMES from the RAILWAYS. For new cables
            delivered and installed by ALCATEL the tests described here can be
            considered as part of ALCATEL's standard practice.

            4.3.1. - TESTS AFTER LAYING THE CABLE AND BEFORE JOINTING: 
                     (only in case of difficult laying or important traction 
                      force)

            The purpose of this test is to check that the quality of the cable
            has not been adveresly affected during laying.

            A back-scattering measurement is done at 1550 nm and in both
            directions for each fibre, and from each origin of laid sections of
            cable.

            4.3.2. - TESTS DURING JOINTING:

            The purpose of this test is to assess the quality of each splice. An
            estimate of the attenuation value is directly indicated by the
            splicing machine.

            4.3.3. - TESTS AFTER JOINTING:

            The purpose of this test is to check the quality of the splices in
            detail.

            An OTDR-based back-scattering measurement is done at 1550 nm and in
            both directions for each fibre, and from each origin of laid
            sections of cable.

      4.4   PARAMETERS TO BE CHECKED:

            For leased fibre, the Chromatic Dispersion (CD) and Polarization
            Mode Dispersion (PMD) parameters need to be checked by the RAILWAYS
            in order to verify whether the fibres meet the specifications of
            HERMES as defined in chapters 2 and 3.

            If these parameters are not available to the RAILWAYS, they should
            request their manufacturer to deliver that data. If PMD data remains
            unavailable, it should be measured on site.

            For new fibre delivered by ALCATEL, the CD and PMD values will be
            made available from factory measurements.

      4.5.  LINK ACCEPTANCE TEST:

            For both fibres leased from the RAILWAYS and cable delivered by
            ALCATEL, tests shall be performed in both directions in the 1550 nm
            window.

            The purpose of the tests is to check that the fibres between two
            stations (nodes and/or regenerators) can operate in the 1550 nm
            window, according to the technical specifications

            The following tests are to be performed :

                  - Back scattering measurements. 
                  - Attenuation measurement.

                  - Section 5 describes the test Methods to be used
                  - Section 6 provides blank copies of the tests sheets to be
                    used

      4.6.  PRINCIPLES OF WORKING:

            4.6.1. - Leased fibre links:

            4.6.1.1. - For input into the Design Report, it is required for
            existing cables that the RAILWAYS supply measurement values as
            defined in 4.6.1.2. For new cables the RAILWAYS are required to
            provide a prediction of values as defined in 4.6.1.2. Assumptions
            used in the prediction to be stated.

            4.6.1.2 - As soon as the fibre is available, fibre measurement
            values are to be provided and communicated to ALCATEL / HERMES by
            the RAILWAYS. ALCATEL will include these values in the Design
            Report.

            The following measures are carried out at 1550 nm:

            ATTENUATION:

                  - Total budget of the route or link
                  - Analysis of each splice and of each particular point where
                    the average attenuation value is equal or more than 0.1 db
                  - Analysis of ODF for each section (<=  0.5 db) 
                  - Return loss ODF for each link (>= 50 db)

            CHROMATIC DISPERSION:

                  - Given by the manufacturer of optical fibre cables.

                  - To be communicated by the RAILWAYS which have this value in
                    their files.

            POLARIZATION MODE DISPERSION:

                  - To be measured on site for each link, if the tests realised
                    in factory are not available

                                     ALCATEL

            4.6.1.3. - ALCATEL will provide to HERMES a report that contains the
            fibre performance data obtained from the RAILWAYS and complete this
            report with an assessment of the received fibre information. If the
            leased fibre data shows that the fibre is not compliant with the
            HERMES specifications, HERMES will, in collaboration with ALCATEL,
            define the necessary actions. Subsequently, HERMES and ALCATEL will
            proceed jointly to incorporate any required changes in the planning
            and the costs into the Design Report.

            If repairs by the RAILWAYS are necessary, ALCATEL will verify the
            new fibre data obtained from the RAILWAYS after their repairs and
            ALCATEL will issue a new report containing the new fibre parameter
            values and the associated assessment by ALCATEL.

            If one or several assessments are neccessary, following the refusal
            of the second one, ALCATEL will ask for a financial compensation
            concerning this extra performance.

            ALCATEL will send HERMES its report, no more than ten working-days
            after receiving test results from the RAILWAYS.

            4.6.1.4. - When asked by HERMES, ALCATEL will perform the acceptance
            tests. These tests will be executed to verify the fibre data made
            available by the RAILWAYS. ALCATEL will execute the link acceptance
            tests as presented in section 4.5. on the fibres that HERMES will
            lease for the link envisaged. Furthermore, if the RAILWAYS cannot
            provide PMD values from their cable manufacturers, ALCATEL will
            verify, at this moment, the PMD through its own tests.

            The test data from the tests performed by ALCATEL will be written on
            measurements sheets as shown in Section 6.

            If the test results obtained from the ALCATEL tests are in
            accordance with the HERMES specifications (as outlined in chapters 2
            and 3), the test sheets will be chronologically signed by:

                  - the RAILWAYS first,
                  - ALCATEL then,

            and later approved by HERMES.

            If the test results obtained from the ALCATEL tests are not in
            accordance with the HERMES specifications, ALCATEL will reject the
            acceptance of these fibres. ALCATEL will then ask HERMES how to
            proceed.

            The tests realised by ALCATEL, at the request of HERMES, will be
            executed only once.

            ALCATEL will send HERMES its report, no more than ten working-days
            after receiving test results signed by the RAILWAYS.

            4.6.2. - Cable links built by ALCATEL for HERMES:

            ALCATEL will execute the link acceptance tests specified in sections
            4.3 and 4.5 to verify conformance with the specifications of chapter
            2. These tests will be executed as part of installation works. CD
            and PMD values will be made available from factory tests.

            The test results obtained from the ALCATEL tests and realised by the
            country ALCATEL's team, will be in accordance with the HERMES
            specifications (as outlined in chapters 2 and 3). The test sheets
            provided by it, will be chronologically signed by:

                  - ALCATEL first, 
            and later approved by HERMES.

            The test results will be provided to HERMES within 5 working-days
            after the completion of the tests.

3 - TEST METHODS

      5.1.  POWER LOSS MEASUREMENTS:

            The purpose of this test is to measure accurately the value of the
            total end-to-end optical loss along the considered link. (It only
            shows the total link loss, without identification of local
            concentration of losses). This test is executed in the field, in
            both directions at 1550 nm.

            The measurement is done with an optical wattmeter connected to one
            end of the fibre and an optical laser light source (at 1550 nm) to
            the other end of the fibre. Measured attenuation is recorded on a
            test sheet, as shown in Section 6 Appendix 3. The test is then
            repeated in the opposite direction.

            The test equipment must be calibrated according to the prescriptions
            of the manufacturer of the test equipment.

            The test provides a global and very accurate measurement of the
            complete link attenuation, and allows the optical power of the
            receiver input to be calculated.

      5.2.  OPTICAL TIME DOMAIN REFLECTORY MEASUREMENTS (O.T.D.R.):

            The purpose of this test is to measure any problem points with
            respect to the transmission or reflection losses of the fibre link
            and to locate the position of these points. This test is executed in
            the field.

            This measurement is done with an optical reflectometer, connected to
            both fibres end points and is used to perform remote measurements.

            The optical reflectometer launches power into the fibre and analyses
            the reflected signal, which permits the fibre attenuation due to
            scattering, absorption and reflections to be calculated.

            Part of the scattered power pulse is sent back to the optical
            reflectometer where it is detected and displayed on a
            cathode-ray-screen.

            The rate of returned power depends on the power launched into the
            fibre and on the back scattering factor of the latter.

            The optical reflectometer displays on its screen the optical power
            of the received signals on a logarithmic scale.

                                     ALCATEL

            Direct reading of the following can be made:

             - On the X axis : distance between each point of the fibre and the
             measuring instrument.

             - On the Y axis : power scattered by each point of the fibre. Any
             sudden drop of the curve means punctual attenuation.

            This measure is performed in both directions of a link. It is the
            average of both results which is considered.

            This measure also provides an accurate value of the Return Loss for
            each O.D.F. situated at both extremities of the measured link.

      5.3.  POLARIZATION MODE DISPERSION MEASUREMENTS (P.M.D.):

            The purpose of this test is to measure the end to end Polarization
            Mode Dispersion of the optical fibre link. This test is routinely
            performed in factory; field tests will be performed if factory data
            is not available for existing cable.

            In this case, this test is carried out in one direction only, and
            the results filled on test sheets (Section 6 - Appendices 4 and 6).

            The source consists of a LED and of a polarizer (transmitter). The
            receiver consists of a MICHELSON's interferometer.

            The measurement is performed by analysing the decomposition into two
            perpendicularly polarized modes of a light signal injected into the
            fibre under test (bi-refrangibility phenomenon).

            The two modes do not propagate at the same speed because of the
            anomalies of the fibre (ovality of the heart, local constraint,
            etc...).

            The measured lateness of transmission (in picoseconds) allows to
            obtain the Polarization Dispersion value in picoseconds per square
            root kilometer (Ps / (checkmark)Km).

      5.4.  CHROMATIC DISPERSION MEASUREMENTS (C.D.):

            The purpose of this test is to measure the end to end Chromatic
            Dispersion of the optical fibre link. This test is routinely
            performed in factory. For existing cables, factory data should be
            made available.

            The Chromatic Dispersion is the difference, expressed in
            picoseconds, between the propagation times of the different modes at
            a specific wavelength (1550 nm), depending on the index of the
            materials used for the construction of the fibre.

            properly cleaned. Here is a short list (for example) of different
            materials to use for cleaning:

             * Dry air spray
             * Alcohol at 90(degrees)
             * Gauze
             * Cotton-buds
               etc....

1.2 Basic Service

Basic service is offered only to locations where, due to the logistics of
network rollout, only one fiber-optic path exists between two locations. All
procedures and performance measures in the Service Level Agreement apply.

Note that Basic service is only a temporary service existing. Subject to
existing contractual commitments, the offering will be withdrawn once Standard
and Premium are available to the location (multiple fiberoptic paths exist).

1.3 Standard service

Standard service has as a prerequisite minimum the availability of two
fiber-optic paths operational between locations. It is designed with extensive
redundancy built-in for high availability performance. The following table
indicates the design criteria and guaranteed operational performance; please see
Schedule 2 for details of the service level agreements.

3. Service Delivery

3.1 General Principles

Service delivery is defined as the period between receipt of HER Service Order
and handover of acceptance-tested operational service. HER will accept Service
Orders up to 3 months prior to the planned 'live' date of a HER node.

This process will be managed through single points of contact from both the
Participating Railway and HER; the HER contact will be assigned upon receipt of
Service Order.

3.3 Service Order Placement

Service Orders may be initiated via fax or E-Mail to the HER point of contact
listed above, and must contain at minimum the following information:

o     request service delivery date
o     type of service required (Standard, Premium)
o     details of bandwidth required including interfacing details
o     the Participating Railway single point of contact for service delivery
      planning

Alternatively, the Participating Railway may proceed directly to complete a
Service Order.

Upon receipt of Service Order, HER will confirm to the Participating Railway
that order is received via fax or E-mail. HER will in parallel determine whether
the requested date is feasible, and will confirm this within 3 days.

HER will then confirm this by sending the complete and verified HER Service
Order with above details and a "Committed Service Delivery Date". This must then
be signed by the contracting party, and returned to HER single point of contact
above.

3.4 Installation

If the Participating Railway requires the service, at the Participating
Railway's cost, HER will provide a service design and coordinate with the
Participating Railway's specified contact persons all installation activities.
Depending on the contracted service, this may include:

o     local access provider equipment installation in the Participating
      Railway's Points of Presence
o     the Participating Railway or local access provider equipment installation
      in HER Points of Presence.

3.5 Acceptance Testing and Commissioning

HER will coordinate with the Participating Railway-specified contact persons all
acceptance testing activities. Depending on the contracted service, this may
include:

o     local access network BIS testing
o     HER end-to-end service BIS testing

3.6 Handover

Upon successful results from HER end-to-end BIS testing, a certificate will be
provided to the Participating Railway. the Participating Railway shall then have
72 hours, measured from time of receipt of HER BIS results, to perform its
internal testing. At end of this period, billing shall commence unless the
Participating Railway notifies HER that its tests have failed, and agreement is
reached with HER to extend BIS testing.

3.7 Escalation

if the stated delivery standards are not met, the following escalation sequence
should be used to find a satisfactory solution.

Planned Works Notification Procedure

HER and local access providers will from time to time undertake scheduled
service-affecting works. HER will inform the Participating Railway by fax
containing the proposed time and date, duration, and description of any such
works. HER has a target of 30 days advance notice. If the proposed time and date
are not acceptable, the Participating Railway must reply immediately with a
preferred alternative. If agreement cannot be reached, HER will decide the time
and date at its discretion, but with the target to minimize the participating
Railway inconvenience.

Planned works are not included in service availability calculations, but are
included in the monthly performance report.

the Participating Railway contacts for planned works notification are to be
formally specified.

                             CONFIDENTIAL TREATMENT

1. Preamble

      1.    By virtue of a convention concerning concession of construction,
            maintenance and operation of motorways concluded with the State on
            June 27, 1990, and approved by a Council of State decree on October
            29, 1990, the SANEF is the concessionaire of a motorway network
            located in Northern and Eastern France (autoroutes ## MATERIAL
            OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
            TREATMENT ##).

      2.    On certain sections of its network described in Appendix 1 to the
            present Convention, the SANEF intends to deploy black optical fibres
            in order to improve the conditions of operating the motorway public
            service for which it is responsible. The SANEF also wishes to
            reserve the part of the optical fibres it does not use for third
            party operators working in the telecommunications field.

      3.    The OPERATOR intends to install and exploit a telecommunications
            network within the framework of article I. 33-1 of the
            Telecommunications Code, and it filed an authorisation application
            for this purpose on November 15, 1996.

      4.    The Parties have consulted each other on a project under which the
            SANEF would make a certain number of black optical fibres along its
            motorway network available to the OPERATOR.

      5.    The present Convention falls within the framewotk of the principles
            of the law of July 26, 1996, regulating telecommunications, and
            hence will observe strict equality of treatment among the various
            operators in connections with making F.o.n. available on the
            equipped motorway sections (cf. the following definitions).

 HAVING SET FORTH THESES PREMISES, NOW THEREFORE THE PARTIES HEREBY ENTER INTO
                            THE FOLLOWING AGREEMENT:

4. Legal nature and scope of the Convention

      4.1 Authorisation to occupy the public domain

      Since the Motorway Network is part of the State's motorway public domain,
      the Convention in particular is tantamount to authorisation to occupy the
      motorway public domain, but does not grant the OPERATOR any real property
      rights to the said public domain (article L.34-1 of the State Domain
      Code).

      4.2 Intuitu personae

      The Convention is concluded intuitu personae.

      The Parties may not transfer their rights and obligations under the terms
      of the Convention except with the other Party's written consent in
      advance. The said consent is hereby granted, subject to advance
      notification, in case of transfer to any subsidiary of one of the Parties,
      or to a company belonging to the group of one of the Parties, or to its
      direct or indirect parent company under the same conditions, as long as
      the assignee company is legally authorised to carry on the activities
      making the present Convention possible.

      4.3 Exclusivity

      For its entire duration, the Convention does not grant any exclusive right
      to the OPERATOR for using the F.o.n. installed by the SANEF, with the
      exception of the ones made available to it under the conditions laid down
      in the said Convention.

      4.4 Contractual relationships - Validity

      The present Convention constitutes the totality of the agreements between
      the Parties.

      The illegality or nullity of any provision whatsoever of the Convention
      that is not of an essential nature shall not cast doubt on the validity of
      the other provisions. The Parties agree to replace the invalid provisions
      by provisions coming as close as possible to their joint intention
      expressed within the framework of the Convention. Any modification of the
      present Convention shall be the object of a rider signed by the authorised
      representative of each of the Parties.

      4.5 Equal treatment

      The OPERATOR shall benefit by right from the most favourable treatment
      granted by the SANEF to an Operator placed in a comparable situation and
      for comparable service.

      4.6 Miscellaneous

      The SANEF agrees not to make F.o.n. available to third parties for
      purposes of supplying optical connectivity.

      In case of a modification of the legal or economic environment in which
      the Parties have contracted that has a significant effect on the
      provisions included in the present Convention, the Parties shall confer to
      agree on the related adaptations.

9. Availability of F.o.n. and of Sites

      9.1 Firm services

      9.1.1 Content

      The SANEF shall make the Equipped Motorway Sections available to the
      OPERATOR in accordance with the technical characteristics spelled out in
      Appendix No. 4 and in accordance with the OPERATOR's needs spelled out in
      Appendix No. 3, namely:

      1. ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ##

      2. ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ##

      3. ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ##

      The OPERATOR shall have to implement, at its own expense, the
      telecommunications equipment it needs to use the F.o.n., and particularly
      the hardware and software making it possible, in case of an interruption,
      to shift operations from one F.o.n. to another and vice versa.

      9.1.2 Deadlines

      The F.o.n. and the Sites shall be made available to the OPERATOR at the
      latest on the dates indicated in the schedule attached in Appendix No. 2.

      In case of a delay in availability on an Equipped Itinerary, the SANEF
      shall compensate the OPERATOR by allocating an hourly credit free to it
      relating to availability of the F.o.n. equal to ## MATERIAL OMITTED AND
      SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## of the
      anticipated annual fee for the Equipped Itinerary in question until ##
      MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
      TREATMENT ## increased to ## MATERIAL OMITTED AND SEPARATELY FILED UNDER
      A REQUEST FOR CONFIDENTIAL TREATMENT ## beyond that date, for each week's
      lateness. However, the penalties as a whole are limited to ## MATERIAL
      OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT
      ## of the amount of the prefinancing mentioned in article 14.3.

      The credit constituted in this way shall be calculated and be deducted
      from the amount of the fee to become due starting with the third year
      following the availability date of the last of the delivered Equipped
      Motorway Sections.

      In case the availability date of the last Equipped Motorway Section comes
      after ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ##, the OPERATOR shall be entitled to cancel the
      present Convention under the conditions mentioned in article 16.1.

      9.1.3 Special conventions regarding Site availability

      At the end of a detailed study, one or several special conventions will
      spell out the technical conditions regarding availability of the Sites and

      This information will also have to be communicated by the SANEF whenever
      the OPERATOR so requests.

      9.2.2 Request for additional F.o.n.

      The OPERATOR may request the SANEF at any time, by registered mail with
      receipt, to have additional F.o.n. made available without reservation in
      the light of the increase in its needs during the present Convention.

      The SANEF undertakes to consider the technical feasibility of making
      additional F.o.n. available in order to meet the OPERATOR's request. The
      SANEF will provide its response within 30 days following the OPERATOR's
      request.

      9.2.3 Request for optional F.o.n.

      The OPERATOR shall also be entitled to reserve optional F.o.n. to be made
      available by the SANEF under the following conditions:

      1) The OPERATOR shall inform the SANEF by registered mail with receipt of
      the number of F.o.n. it wants to have reserved (hereinafter: "the
      Request").

      The Request may not bear on more F.o.n. than exploited by the OPERATOR.

      2) The SANEF has two weeks to acknowledge the Request, which may be
      rejected only in case of circumstances beyond its control. After that
      time, the Request is considered to have been accepted by the SANEF subject
      to payment by the OPERATOR of an amount equal to ## MATERIAL OMITTED AND
      SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## of the
      amount of the annual fee relating to the request calculated on the price
      terms provided for in the present Convention. Payment shall have to be
      made within 30 days starting with the SANEF's explicit or tacit response,
      failing which the Request will no longer be considered as having been
      accepted.

      3) The Request is valid for ## MATERIAL OMITTED AND SEPARATELY FILED UNDER
      A REQUEST FOR CONFIDENTIAL TREATMENT ## starting with the date of
      acceptance of the Request, during which the OPERATOR may request at any
      time, by registered mail with receipt addressed to the SANEF, to have the
      F.o.n. that are the object of the Request made available. The SANEF will
      make the F.o.n. in question available within 2 weeks following the date of
      receipt of the above-mentioned letter and will deduct the amount of the ##
      MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
      TREATMENT ## paid in connection with the reservation from the fee for the
      F.o.n. that are the object of the Request.

      4) During the period of Request validity, and in case the SANEF's
      available F.o.n. are in the limit of capacity, the SANEF may request the
      OPERATOR at any time, by registered mail with receipt, to make a decision
      as to the final nature of the availability of the F.o.n. that are the
      object of the Request.

      The OPERATOR shall then have a period of 2 weeks starting with the date of
      receipt of the above-mentioned letter to make its response by registered
      mail with receipt addressed to the SANEF.

      In the absence of a response within that period or in case of a negative
      response, the SANEF:

      - shall be entitled to exploit the F.o.n. in question itself or make them
      available to another Operator;

      - to return the sum paid to the OPERATOR pursuant to section 2 of the
      present article.

      5) One month before the end of the reservation, the SANEF will ask the
      OPERATOR by registered mail with receipt whether it wants to renew its
      option. If so, the latter shall have to again pay an amount equal to ##
      MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
      TREATMENT ## of the annual fee relative to the Request. In this case, the
      amount of ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ## paid by the OPERATOR for the past year shall
      definitively remain the SANEF's property.

      9.2.4 Making additional F.o.n. available

      The technical conditions relating to making additional F.o.n. available
      will be defined by a rider modifying Appendix No. 3 and, if the case
      arises, Appendix No. 6 section 3.2 "motorway sections". The additional
      F.o.n. will be subject to the same financial conditions as the ones laid
      down in the present Convention. The base price of the work unit is defined
      in Appendix 6. However, in case of prefinancing, the base price of the
      work unit shall be the one for the year 1996/1997 or ## MATERIAL OMITTED
      AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## per
      linear meter per year. The payment schedule appearing to Appendix No. 8
      will also be updated.

10. Technical provisions relative to the work

      information it needs to evaluate the progress and the quality of the work
      of installing the Optical Cable.

      The means used to reach this objective concern access to the technical
      documents relative to the project as well as the response to the
      OPERATOR's written questions.

      Some job site inspections will be arranged by SANEF for the OPERATOR's
      benefit, at the latter's inquest.

      10.2 Sites

      10.2.1 Evaluation of OPERATOR's needs

      With a view to establishing the special convention(s) spelling out the
      conditions of making the Sites available, upon signature of the Convention
      the Parties shall inspect the Sites. The OPERATOR shall then indicate by
      registered mail with receipt addressed to the SANEF the list of the SANEF
      Sites at which it wishes to install its telecommunications equipment or
      any other equipment, required for exploitation of the F.o.n., or failing
      this, the Sites that can be installed by the OPERATOR. For each Site the
      OPERATOR shall supply specifications including, in particular, a detailed
      layout plan of the equipment items as well as the specifications of the
      required environment.

                                                                              12


      The OPERATOR's specifications will be considered by the SANEF before any
      work within a period of one month starting with the date of receipt
      thereof. They shall give rise to a technical and financial evaluation.

      In the interest of proper management of the motorway public domain, the
      preferred solution is the one calling for installation of the OPERATOR's
      equipment in the SANEF Sites in which private spaces are to be arranged
      for the OPERATOR's benefit.

      Furthermore, except in its private spaces in the SANEF Sites, the OPERATOR
      shall not be entitled to oppose the presence of equipment belonging to the
      SANEF or to other OPERATORS.

      The OPERATOR may not oppose installation of a technical shelter near its
      Site.

      10.2.2 Improvement of the SANEF Sites

      If the SANEF Sites made available in accordance with the special
      conventions mentioned in article 10.2.1 are to be the object of other
      improvements at the OPERATOR's request, such as, for instance, security of
      the energy supply, air conditioning or access control, etc., the work will
      be performed by the SANEF and will be paid for by the OPERATOR in
      accordance with the financial evaluation that will have been made in
      advance and which will have been approved by the two Parties.

      In case the improvements financed by the OPERATOR are also used by other
      Operators, the incoming Operator will be asked by the SANEF to make an
      improvement contribution and this will be rebated to the OPERATOR in
      proportion to the surface area occupied.

      10.2.3 Construction of Sites by the OPERATOR

      In case the SANEF cannot make the Sites desired by the OPERATOR available,
      the latter is authorised to construct pursuant to the technical conditions
      spelled out in a special convention in accordance with article 10.2.1 and
      under the following conditions:

      1.    The Sites will be built by the OPERATOR, at its own expense, the
            latter also paying the expenses induced by the work (fencing
            modification, etc.),

      2.    The Sites shall be of a model approved by the SANEF,

      3.    The Sites may not occupy a surface area of more than 15 square
            meters,

      4.    A plan of the Site's territorial area will be drawn up by the SANEF
            for each place in question and will be signed by the two Parties'
            contacts designated in article 5,

      5.    The OPERATOR shall see to installation and consumption of the
            electricity, and shall be entitled to make the best possible use of
            the existing electrical installations,

      6.    The Sites shall always be maintained in a good condition of
            maintenance,

      7.    The OPERATOR shall see to the required administrative formalities.

      10.2.4 OPERATOR's equipment installations

      The OPERATOR or its representative shall enjoy continuous access to the
      Sites or to the territories in accordance with the safety rules spelled
      out by SANEF in Appendix No. 5

      10.2.5 Use and maintenance of the Sites

      The OPERATOR undertakes to keep the private space of the SANEF Sites
      reserved for it in good maintenance condition. However, it shall reimburse
      the SANEF for its share of the electricity consumed. It shall remain fully
      responsible under all circumstances for its use of its private spaces. In
      this connection, it will have to take out insurance making it possible, at
      the appropriate time, to cover the various risks connected with its use of
      the Sites.

11. Technical provisions relative to operations

      11.1 Acceptance

      11.1.1 Acceptance of the F.o.n. by the SANEF

      As soon as SANEF pronounces acceptance of the F.o.n. vis-a-vis its
      manufacturer in an F.o.n. district, the SANEF shall inform the OPERATOR by
      registered mail with receipt that the F.o.n. in question may become the
      object of acceptance by the OPERATOR and it shall inform it of the result
      of the measurements made.

      11.1.2 Acceptance of the F.o.n. by the OPERATOR

      In the interest of making sure that the technical characteristics of the
      F.o.n. made available to it meet the technical specifications laid down in
      Appendix No. 4, the OPERATOR must make its own acceptance tests, F.o.n.
      District by F.o.n. District, pursuant to Appendix No 4, within a maximum
      of 2 weeks following the date of receiving the registered letter with
      receipt mentioned in article 11.1.1.

      The following constraints shall be observed:

      1.    After having informed the SANEF of the place and date of acceptance
            with 48 hours' notice, the OPERATOR shall carry out the test
            operations relating to acceptance of the F.o.n. The said operations
            shall be carried out as the SANEF makes F.o.n. available in each
            F.o.n. District.

      2.    The results of the acceptance tests shall be recorded in minutes
            concerning the operations prior to acceptance, to be drawn up and
            signed by the Parties present at the time of the operations. If the
            SANEF is absent, the minutes shall be applicable to it.

      3.    If the acceptance tests are positive, the OPERATOR shall send an
            acceptance report signed by it within one week following the date of
            the tests, by registered mail with receipt, to the SANEF.

      4.    In case of difficulties, the acceptance test operations shall have
            to be renewed within 30 days at the latest starting with the date of
            the first test operation.

      5.    If the OPERATOR does not pronounce acceptance of the F.o.n. at the
            end of the latter period on the ground that the F.o.n. made
            available do not meet the technical

                                                                              14


            specifications laid down in Appendix No. 4, the OPERATOR shall be
            entitled to cancel the Convention under the conditions of article
            16.1. The same applies when the lack of acceptance results from
            SANEF's absence.

      6.    If the OPERATOR does not pronounce acceptance of the F.o.n. within
            the periods indicated for any reason other then the ones described
            above, acceptance is considered to have occurred.

      11.1.3 Acceptance of the SANEF Sites

      The SANEF Sites shall be accepted by the OPERATOR at the same time as the
      F.o.n. Districts concerned and in accordance with the specifications
      appearing in the special convention mentioned in article 10.2.1 of the
      present Convention.

      11.1.4 Acceptance of an Equipped Motorway Section

      When the OPERATOR has pronounced acceptance of all of the F.o.n. Districts
      and of the SANEF Sites made available to the OPERATOR by SANEF in one and
      the same Equipped Motorway Section, the latter is considered to have been
      accepted by right.

      11.1.5 Compliance of the OPERATOR Sites

      On the basis of the documents provided for in article 10.2.3, the
      compliance of the OPERATOR Sites will be checked by the SANEF on a date
      set by the OPERATOR, the said inspection giving rise to signature of a
      report.

      11.1.6 Compliance of the OPERATOR's technical equipment

      The compliance with specifications of the OPERATOR's technical equipment
      will be checked by the SANEF at the same time and on the basis of the same
      procedure as described in article 11.1.5, and within the limits of what is
      necessary to verify the absence of disturbances.

      11.2 Maintenance

      The SANEF warrants the OPERATOR with respect to the compliance of the
      F.o.n. made available to it with the technical specifications spelled out
      in Appendix No. 4, and their proper operation for the entire duration of
      the present Convention.

                                                                              15


      11.2.1 Preventive maintenance

      The list of the work on motorways planned by the SANEF that could
      interfere with proper operation of the F.o.n. will be transmitted to the
      OPERATOR on the occasion of each updating, and if possible 45 days before
      the start of work. The SANEF will inform the OPERATOR of the provision to
      be adopted to minimise possible disturbances.

      If the case arises, for unplanned motorway work, SANEF will inform the
      OPERATOR in accordance with the procedure to be defined as soon as it
      becomes aware thereof and it will indicate the provisions adopted to
      minimise possible disturbances.

      Preventive maintenance consists in carrying out the following:

      1.    semi-annually:

            -     a check on the mechanical and optical condition, including the
                  verification of the Connectors,

            -     a verification of the quality of the F.o.n. by checking on its
                  performance level in accordance with the technical
                  specifications described in Appendix No. 4.

      2.    every two months:

      -     a routine inspection making it possible to detect possible
            deterioration including civil engineering, or departures from
            desired performance.

      In particular preventive maintenance includes the labour and the
      replacement of defective equipment as well as keeping maintenance
      documentation and a work ledger up to date.

      All of the work carried out by the SANEF on the F.o.n. and Connectors,
      including on behalf of third parties, as well as the events having given
      rise thereto must be entered in a ledger called "journal de bord" kept on
      the SANEF premises and which can be consulted by the OPERATOR.

      The "journal de bord" must include the following information as a minimum
      for each SANEF intervention: date, starting and ending time, nature of the
      anomalies noted, work carried out and subassemblies replaced, indication
      of the checks and measurements made, and an account of the incidents or
      difficulties encountered.

      Preventive maintenance is carried out In accordance with a schedule drawn
      up by agreement with the OPERATOR.

      The definition of the test, measurements and performance levels is given
      in Appendix No. 4.

      It must be possible to carry out the preventive maintenance work without
      interruption. To this end, the SANEF shall keep at least one pair of
      F.o.n. known as "manoeuvring fibres" on each side of the motorway that can
      be used by the various Operators. This "manoeuvring" connection will have
      to be as close as possible to the connection made available and comparable
      in every respect. It will be accepted and maintained in identical fashion.

      11.2.2 Remedial maintenance

            11.2.2.1 General principles

      The SANEF, at its own expense, shall see to repair of the F.o.n. made
      available to the OPERATOR in case of interruption or of dysfunction.

      The OPERATOR will be reimbursed for any interruption for the amount of the
      fee on the Equipped Itinerary in question for the duration of the
      interruption upon submission of an invoice payable at thirty (30) days or
      in the form of an hourly credit, at its choice.

      The remedial maintenance conditions will be assured by the SANEF under the
      conditions described below.

            11.2.2.2  Alert procedure

      The SANEF shall have to install means making it possible to receive
      telephone calls and faxes 7 days a week, 24 hours a day.

      As soon as the failure of an F.o.n. is noted, the OPERATOR shall inform
      the SANEF of this fact by telephone and fax.

      The OPERATOR shall make sure that the failure does not result from
      equipment it has connected to the F.o.n. made available or from the part
      of the optical connection between the Connector and its equipment, for
      which the SANEF is not responsible.

      If appropriate, the OPERATOR shall confirm its request to the SANEF for
      intervention by telephone and fax.

      At the time of such interventions, the SANEF shall have to have qualified
      staff and the required tooling to carry out all checks and to make the
      analyses and the repair.

      When there has been a request for intervention, the SANEF shall designate
      a contact who will be able to supply the OPERATOR with full information
      concerning the progress made in putting the optical connection back into
      proper condition.

      The work periods begin starting at the time of receipt of the work request
      and are specified below.

      However, the SANEF undertakes to see to it that the required means are
      applied to avoid disturbing the operation of the F.o.n. made available to
      the OPERATOR.

      In case the work should necessarily affect proper operation of the F.o.n.,
      the SANEF shall consider with the OPERATOR, as soon as possible and in any
      event before the startup of the work, except in case of force majeure, the
      steps to be taken to maintain the same service quality.

      12.3 Work on the telecommunications network

      The SANEF shall supply the OPERATOR with continuous information concerning
      the state of the work relating to the F.o.n. In case the work should
      necessarily affect proper operation of the F.o.n., the SANEF shall
      consider with the OPERATOR, as soon as possible and in any event before
      the startup of the work, except in case of force majeure, the steps to be
      taken to maintain the same service quality.

13. Liability

      13.1 General principle

      The Parties are liable between themselves for any direct damage resulting
      from the existence and the operation of their installations on the
      Motorway Network.

      The OPERATOR undertakes to strictly respect the conditions regarding
      operation of its equipment and of the F.o.n. made available to it laid
      down in the regulations applicable to the telecommunications sector, and
      to obtain all advance authorisations required. The SANEF may not be held
      liable in any way in this connection.

                                                                              20


      13.2 Equipment compatibility and maintenance

      Each Party assures itself and warrants the other with respect to the
      compliance of the installation of its equipment with the standards and
      practices in the business, particularly with the recommendations relative
      to electromagnetic compatibility, and that operation thereof is compatible
      with the other Party's equipment.

      Each Party remains responsible for proper performance of the present
      article.

      The OPERATOR shall have to monitor and maintain its equipment in a good
      maintenance condition, at its own expense and risk, so as not to cause any
      disturbance and not to create any danger to the motorway public domain
      under concession and operation thereof. In case of a failure or of
      insufficiency of the measures adopted for such maintenance, the SANEF
      shall be entitled to have the required work done at its own initiative,
      after having served formal notice, except in case of urgency, on the
      OPERATOR by registered mail with receipt calling on it to record, in the
      Parties' presence, the work required and to carry it out within 2 weeks.

      13.3 Insurance

      Each Party has taken an insurance policy out with an insurance company
      represented in France concerning the Sites and covering the risks of fire,
      explosion, water damage, public liability generally, and all risks
      connected with its activity in particular linked with the Convention.

      A Party may not be held liable in any way for the insufficiency of the
      coverage taken out by another Party.

14. Financial provisions

      14.1 Fees

      In exchange for the authorisation to occupy the motorway public domain and
      for the availability of the F.o.n. and of the Sites provided for under the
      present Convention, the OPERATOR shall be required to pay two fees to the
      SANEF:

      1.    an annual fee (R1) for the availability of the F.o.n. (cf. article
            9.1.1) in an amount laid down in Appendix 6 for all of the Equipped
            Motorway Sections delivered.

            If the OPERATOR sees to prefinancing in accordance with articles
            14.3.2 and 14.3.3 below, the duration discount (3.4.2 of the price
            list in Appendix No. 6) shall apply as of the first year and for the
            entire duration of the present Convention, to all F.o.n.
            availabilities at the rate of ## MATERIAL OMITTED AND SEPARATELY
            FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ##. In addition,
            the base price of the work unit shall, for the duration of the
            Convention, be the one in effect in the year of signature of the
            present Convention.

      2.    an annual fee (R2) for making the Sites available, which shall be
            calculated excluding taxes in accordance with the fee schedule laid
            down in Appendix 6 (point 6).

      The two fees (R1 and R2) shall follow the following rules:

      -     the beginning date of their payability for an Equipped Itinerary
            shall be the Availability Date of the last Equipped Motorway Section
            of the said Itinerary.

      -     invoices shall be issued for them in accordance with the procedures
            of article 14.3.2 below.

      14.2 Revision

      The amount of the fees provided for in article 14.1 shall be revised
      annually as follows:

            ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
            CONFIDENTIAL TREATMENT ## in which:

      R = Revised fee: R1 or R2

      Ro= Fee corresponding to the latest known indices at the time of signature
      of the Convention

      So = The weighted general index of salaries in the electronic and
      engineering industries as published by the INSEE

      FCI o = The base index for insulated wires and cables established and
      published by the INSEE under the reference NAF No. 2818/36

      S and FCI = The revision indices, the latest indices known on the
      invoicing date

      The variation shall be taken into account and applied every year on
      January 1.

      The Parties agree to renegotiate the choice or structure of the revision
      index adopted if ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST
      FOR CONFIDENTIAL TREATMENT ## is less than or equal to ## MATERIAL OMITTED
      AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## or
      greater then or equal to ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A
      REQUEST FOR CONFIDENTIAL TREATMENT ##.

      In case an index disappears, the calculation shall be made by using the
      substitute index and the required correlation coefficient.

      14.3 Payment and invoicing procedures

      14.3.1 Downpayment

      The OPERATOR shall pay the amount of ## MATERIAL OMITTED AND SEPARATELY
      FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## excluding taxes to the

      On the day of signature of the present Convention, the SANEF shall supply
      the OPERATOR with the corresponding invoice, which the OPERATOR shall pay
      within two weeks.

      14.3.2 Prefinancing option

      The procedures for payment of the R1 fee shall vary depending on whether
      the OPERATOR has been able to use its option to prefinance the work of
      installing the F.o.n. under the terms of article 14.3.3 below. In this
      connection, the OPERATOR shall inform the SANEF of its decision to provide
      or not provide the said prefinancing by registered mail with receipt sent
      as soon as possible, and at the latest on May 15, 1997.

      14.3.3 Payment of prefinancing of the F.o.n.

      prefinancing (P) equal to ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A
      REQUEST FOR CONFIDENTIAL TREATMENT ## excluding taxes, payable in three
      instalments by April 20, 1997, and releasing the OPERATOR from payment of

      but before ## MATERIAL OMITTED AND SEPARATELY FILED UNDER

      and P3 at the same time as P1.

      In case of early payment, a payment discount shall be granted on the basis
      of the overnight rate on the money market less ## MATERIAL OMITTED AND
      SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ##.

      If payment of P1 has not been made by ## MATERIAL OMITTED AND SEPARATELY
      FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## at the latest, the
      Parties shall consider that the OPERATOR is not providing prefinancing,
      and if the OPERATOR fails to call upon the termination clause stipulated
      in article 18, the F.o.n. shall be made available under the conditions of
      the present Convention without any prefinancing discount, R1 being payable
      as of the first year the F.o.n. are made available.

      In case of late payment of the prefinancing instalments (P2) and (P3), the

      After the deadline for payment of the prefinancing instalments (P2) and
      (P3), the SANEF shall be entitled to serve formal notice to pay on the

      formal notice, the SANEF shall be entitled to cancel the present
      Convention under the conditions described in article 16.1.1.2.

      In exchange for the prefinancing and subject to full payment thereof by ##
      MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
      TREATMENT ## the OPERATOR shall benefit for the duration of the present
      Convention from an exceptional discount on the R1 fee, which shall vary
      depending on the P1 transfer date in the following proportions:

      - if P1 is paid between ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A
      REQUEST FOR CONFIDENTIAL TREATMENT ## and ## MATERIAL OMITTED AND
      SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## the amount
      of the exceptional discount on R1 shall be equal to:

            ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
            CONFIDENTIAL TREATMENT ## per day's lateness starting on ## MATERIAL
            OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL

      In the absence of payment of the entire prefinancing (P) on ## MATERIAL
      OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ##
      and in the absence of cancellation of the present Convention by the SANEF
      or the application of the termination clause stipulated in article 18, the
      F.o.n. shall be made available under the conditions of the present
      Convention, but without any prefinancing discount, the first invoice in
      connection with R1 being payable as of the date of availability of the
      last Equipped Motorway Section of each Equipped Itinerary. In this case,
      the amounts paid to the SANEF as prefinancing shall be returned to the
      OPERATOR within three (3) days, with the exception of the downpayment
      mentioned in article 14.3.1 of the present Convention, which shall be
      applied to the amount of the said invoice.

      F.o.n. and of the Sites

            14.3.4.1 Invoicing procedure

      The invoices are sent to the OPERATOR by registered mail with receipt.

      i) In case of prefinancing (articles 14.3.2 end 14.3.3), at the end of a
      period of three years starting with the date of availability of the last
      Equipped Motorway Section of an Equipped Itinerary, an invoice shall be
      issued less than 60 days before the due date in an amount equal to a
      fraction of the annual fee calculated in proportion to the time remaining
      until the end of the year.

      ii) In the absence of prefinancing, an invoice will be issued less than 60
      days before the availability date of each Equipped Itinerary in an amount
      equal to the annual amount of the corresponding R1 fee, reduced by the
      downpayment made pursuant to article 14.3.1.

      In November 1997, a third invoice will be issued in an amount equal to the
      fraction of the R1 fee in proportion to the time that has elapsed since
      the availability date of the last Equipped Motorway Section of each of the
      Equipped Itineraries.

15. Declarations and guarantees

      The SANEF declares and warrants the OPERATOR:

      1.    that it is and remains the holder of the Convention for the
            concession of construction and operation of motorways concluded with
            the State on June 27, 1990, and approved by a Council of State
            Decree on October 29, 1990, pursuant to the terms of the convention
            published in the JORF on October 31, 1990;

      2.    that it is unaware of any fact or event of such nature as to entail
            total or partial invalidation of the said concession;

      3.    that it has seen to the steps preliminary to installation of the
            F.o.n.;

      4.    that it is authorised to install F.o.n. along the motorway public
            domain for which it is the concessionaire;

      5.    that it is authorised to make the above-mentioned F.o.n. available
            to the OPERATOR under the present Convention.

16. Cancellation

      In case one of the Parties does not perform an essential obligation of the
      present Convention, particularly in case the required provisions are not
      adopted by the SANEF to ensure the availability of the F.o.n., the other
      Party shall serve formal notice on it by registered mail with receipt
      calling on it to perform within a minimum period of 30 days starting with
      the date of receipt of the said letter, in the absence of a stipulation to
      the contrary laid down in the present Convention under the following
      conditions:

      If the formal notice produces no effect, the Party sending it shall be
      entitled to cancel the present Convention under the following conditions.

      The statement of cancellation for any reason whatsoever by one or the
      other of the Parties shall be made in a registered letter with receipt

      D is equal to the exact duration of use of the F.o.n. between the date of
      availability of the last Equipped Motorway Section and the date of
      cancellation, expressed in fractions of a year.

      The amounts paid in advance to the SANEF by the OPERATOR for which the
      OPERATOR may be reimbursed by the SANEF under the stipulations of the
      present article shall be increased on the basis of the T4M money market
      rate.

      The cancellation penalties provided for in the present article shall be

      arises, under a particular provision of the present Convention for the
      reason having led to cancellation thereof.

      OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT
      ##. The SANEF shall return to the OPERATOR the balance of the sums to the
      OPERATOR's credit in the SANEF accounts.

17. Force Majeure

      Under the terms of the present Convention, a case of force majeure shall
      be any circumstance beyond the Parties' control that is irresistible and
      unpredictable in the meaning of the Council of State precedents.

      The Parties agree that one will treat as a case of force majeure a traffic
      accident or a demonstration on the motorway simultaneously affecting both
      traffic directions, cases of external strikes, and sabotage.

      No Party shall be considered as in default or as failing to meet its
      contractual obligations in case performance of its obligations is
      prevented by a case of force majeure.

      The Parties shall consult each other to limit the effects of the case of
      force majeure as far as possible.

18. Condition subsequent

      The OPERATOR has applied to the European Investment Fund for guarantees in
      an amount of ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR
      CONFIDENTIAL TREATMENT ## in order to be able to obtain a bank loan with a
      view to assuring the financing of its pan-European telecommunications
      network.

      Within 3 days following notification of the OPERATOR by the European
      Investment Fund of its decision to grant the said guarantees, the OPERATOR
      shall inform the SANEF of the said decision by registered mail with
      receipt.

      If the OPERATOR has not obtained the above-mentioned guarantees from the
      European Investment Fund before May 20, 1997, the present Convention shall
      be terminated by right if the OPERATOR so decides.

      In case the OPERATOR intends to call upon the present termination clause,
      it shall notify the SANEF by registered mail with receipt by May 23, 1997,
      of the European Investment Fund's decision refusing to grant the said
      guarantee and of its decision to call upon the present clause.

      In case of application of the termination clause by the OPERATOR, the
      SANEF shall retain the downpayment provided for in article 14.3.1 of the
      present Convention as fixed and definitive compensation.

19. Disputes

      The present Convention is governed by French law. Any dispute relative to
      the formation, construction, performance or cancellation of the present
      Convention that cannot be resolved by the Parties in a friendly fashion
      shall be submitted to the competent courts of Paris.

20. Election of domicile

      The Parties elect domicile at the respective addresses indicated in
      article 5 for management of the present Convention. Notifications by
      registered mail with receipt by telephone and/or by fax shall be sent to
      the said addresses.

================================================================================

1.   FEE CALCULATION (R1)

The R1 fee due in exchange for the availability of F.o.n. is calculated by
multiplying the base price of the work unit by the number of work units defined
below (ss. 3.1), reduced by the general discounts defined in ss. 3.4 if any.

The obtained result is then revised in accordance with a revision formula
defined in the Convention.

2.   BASE PRICE OF THE WORK UNIT

The base price excluding taxes of the work unit expressed in KF (000 F) per km
is defined in the light of the year of contract signature regarding availability
of the pair of F.o.n. in accordance with the table given below.

- --------------------------------------------------------------------------------
   1996-1997       1998         1999         2000          2001         2002

## MATERIAL OMITTED AND SEPARATELY FILE UNDER A REQUEST FOR CONFIDENTIAL 
TREATMENT ##
- --------------------------------------------------------------------------------

Remark: The values given in the above table are values as of December 1996,
and are revised in accordance with the revision formula given in the
Convention.

3.   CALCULATION OF THE NUMBER OF WORK UNITS

3.1  Definition

The number of work units (U.O) made available for a year is equal to the length
of an Equipped Motorway Section in kilometres multiplied by the number of pairs
made available.

For instance, on a 100-kilometre Motorway Section, a pair of F.o.n. made
available represents ## MATERIAL OMITTED AND SEPARATELY FILE UNDER A REQUEST FOR
CONFIDENTIAL TREATMENT ## for the year in question.

3.2  Motorway sections

The work units may be requested by the Operators on the following Motorway
Sections:

- --------------------------------------------------------------------------------
Motorway                      Section                       Length

(*) this section cannot be taken separately. It must necessarily be associated
with at least one of the other two sections of which ## MATERIAL OMITTED AND
SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## constitutes the
extremity.

3.3  Discounts by section

Each motorway section defines a certain quantity to U.O corresponding to the
length of the said section.

3.3.1 Quantitative discounts

     ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
     TREATMENT ## discount is granted for the first pair of F.o.n.

     ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
     TREATMENT ## discount is calculated on the length of the section in
     question for the second pair of F.o.n., which defines a new quantity of
     U.O.

     ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
     TREATMENT ## discount is calculated on the length of the section in
     question starting with the third pair of F.o.n., which defines a new
     quantity of U.O.

3.3.2 "Securisation"

If an operator wishes to make a pair of F.o.n. secured, the said security is
obtained by using another pair of F.o.n. located on the other side of the
motorway.

The number of U.O associated with a pair used on a standby basis is equal to ##
MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT
## of the number of U.O of the pair made secured in this way, starting with the
first F.o.n. requested by the operator.

3.3.3 Calculation of the number of U.O per section

The number of U.O for each section is the sum of the different U.O
associated with the F.o.n. requested for the said section.

3.4  Additional discounts by pairs

Additional discounts are applied to each pair of F.o.n. The said discounts may
be cumulated in succession in the following order:
<PAGE>   48

                             CONFIDENTIAL TREATMENT

                                                                              33

3.4.1 Length discount

If a pair of F.o.n. is requested for all sections offered by the SANEF, then
the said F.o.n. benefits from a "length discount" of ## MATERIAL OMITTED AND
SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ##

3.42 Duration discount

if a pair of F.o.n. is requested for a duration of more than ## MATERIAL OMITTED
AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## years, an
additional discount is applied to the U.O reduced by the length discount if
any, pursuant to the following scale:

- --------------------------------------------------------------------------------
                Duration                               Discount
- --------------------------------------------------------------------------------

                            CONFIDENTIALITY AGREEMENT
<PAGE>   51

                            CONFIDENTIALITY AGREEMENT

PARTIES:

HERMES EUROPE RAILTEL B.V., "HER", a Dutch Company, whose registered office is
at Radioweg 2, 1305 KW Almere, The Netherlands, and whose principal place of
business is at Avenue Louise 106, 1050 Brussels, Belgium; and

SOCIETE DES AUTOROUTES DU NORD ET DE L'EST DE LA FRANCE S.A.
"SANEF", of 4l Bis Avenue Bosquet 75007 Paris France.

In connection with a potential transaction by and between HER and SANEF relating
to the supply by SANEF of dark fibre and ancillary accommodation and services to
HER (the Transaction), the Parties have requested certain information concerning
each other and their respective affiliates. As a condition to providing
confidential or proprietary information the Parties agree to treat the
Evaluation Information (as defined below) as confidential in accordance with the
provisions of this Agreement.

Evaluation Information is defined as any technical or commercial information
concerning a Party (the Disclosing Party) which has been or may be provided by
the Disclosing Party or any of its affiliates or their respective directors,
officers, employees or agents, in oral, written, visual, magnetic, electronic or
other form to the other Party (the Recipient) or to any Recipient's directors,
officers, employees, lawyers, accountants, financial advisors or other agents
(collectively, Representatives), regardless of whether specifically identified
as confidential, together with analyses, compilations, studies or other
documents prepared by Recipient or Recipient's Representatives, which contain or
otherwise reflect such information, or Recipient's review of, or interest in the
Disclosing Party.

The term 'Evaluation Information' shall not include any information which:

     i.   was or becomes generally available to the public other than as a
          result of a disclosure by Recipient;

     ii.  was available to Recipient on a non confidential basis prior to its
          disclosure to the Recipient by the Disclosing Party; or

     iii. was or becomes available to Recipient on a non-confidential basis from
          a source other than the Disclosing Party or its affiliates, provided
          that such source is not bound by a confidentiality agreement with the
          Disclosing Party.

Recipient hereby agrees that the Evaluation Information will be used solely for
the purpose of evaluating the Transaction and that such information will be kept
confidential by Recipient and its Representatives and will not be disclosed or
divulged by Recipient or any of its Representatives without the express prior
written consent of the Disclosing Party. However, Recipient is permitted to
disclose the Evaluation Information to those of its Representatives (other than
any such person or a director, officer, employee or a substantial investor in a
direct competitor of the Disclosing Party) who need to know such information for
the purpose of evaluating the Transaction. Recipient agrees that such
Representatives shall be informed of the confidential nature of such
information, shall be directed by Recipient to treat such information as
confidential and shall agree to be bound by the provisions of this
Confidentiality Agreement.
<PAGE>   52

Recipient will be responsible for any breach of this Confidentiality Agreement
by its Representatives (including employees who, after the first date of
disclosure of Evaluation Information hereunder, become former employees).
Recipient agrees, at its sole expense, to take all reasonable measures,
including but not limited to court proceedings, to restrain its Representatives
from unauthorised disclosure or use of Evaluation Information.

In addition, without the prior written consent of the Disclosing Party,
Recipient will not disclose and will direct its Representatives not to disclose
to any person the fact that discussions or negotiations are taking place
concerning a possible Transaction, or any of the terms, conditions or other
facts with respect to any such Transaction, including the status thereof. The
term 'person' as used in this letter shall be broadly interpreted to include
without limitation any individual, governmental body, partnership, corporation
or other entity.

Upon the request of the Disclosing Party, Recipient will promptly deliver to the
Disclosing Party all documents provided by the Disclosing Party or any of its
affiliates or their respective directors, officers, employees, or agents, to
Recipient or its Representatives constituting Evaluation Information, without
retaining any copies, extracts or other reproductions of all or part thereof. In
the event of such request, all documents, memoranda, notes and other materials
prepared by Recipient or its Representatives based on the Evaluation Information
will be promptly destroyed. Notwithstanding the return or destruction of any
Evaluation Information and materials based on the Evaluation Information,
Recipient will continue to be bound by its obligations of confidentiality and
other obligations hereunder.

Although the Disclosing Party and its affiliates have endeavoured to include in
the Evaluation Information known to them which they believe to be relevant for
the purpose of Recipient's investigation, Recipient understands, acknowledges
and agrees that neither the Disclosing Party nor any of its affiliates, nor any
of their respective directors, officers, employees or agents, makes any
representation or warranty, expressed or implied, as to the accuracy or
completeness of the Evaluation Information. Recipient understands, acknowledges
and agrees that neither the Disclosing Party nor any of its affiliates, nor any
of their respective directors, officers, employees or agents shall have any
liability to Recipient or any of Recipient's Representatives resulting from the
use of any of the Evaluation Information by Recipient or Recipient's
Representatives.

The Confidentiality Agreement shall be governed by and construed in accordance
with the laws of France.



Approved and agreed:

               Rider No. 1 to the Convention of February 3, 1997

                          SANEF/ HERMES EUROPE RAILTEL

================================================================================

Article 1

The second sentence of article 14.3.2 of the Convention is modified as follows:

"In this connection, the OPERATOR shall inform the SANEF of its decision to
provide or not provide the said prefinancing by registered mail with receipt
sent as early as possible, and by May 22, 1997, at the latest."

Article 2

Article 14.3.3 is cancelled and is replaced by the following wording:

"The OPERATOR shall have the option of providing, to the SANEF's benefit,
prefinancing (P) equal to ## MATERIAL OMITTED AND SEPARATELY FILED UNDER A
REQUEST FOR CONFIDENTIAL TREATMENT ## excluding taxes payable by June 20, 1997,
and releasing the OPERATOR from payment of the R1 fee for ## MATERIAL OMITTED
AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## years
starting with the date of availability of the last Equipped Motorway Section of
each Equipped Itinerary, within the framework of the payment schedule in
Appendix 8.

The SANEF shall issue an invoice addressed by registered mail with receipt to
the OPERATOR upon receiving the registered letter mentioned in section 14.3.2
informing it of its decision to provide the prefinancing. The downpayment made
pursuant to section 14.3.1 shall be applied to the amount of the prefinancing
invoice (P).

Payment of the prefinancing shall occur upon submission of the corresponding
invoice by bank transfer to a SANEF account within a maximum of 30 days starting
with the day of dispatch of the letter mentioned in section 14.3.2, and at the
latest on June 20, 1997.

In case of early payment, a payment discount will be granted on the basis of the
money market overnight rate less ## MATERIAL OMITTED AND SEPARATELY FILED UNDER
A REQUEST FOR CONFIDENTIAL TREATMENT ##.

If payment of P has not been made by June 20, 1997, the Parties shall consider
that the OPERATOR is not providing prefinancing, and unless the latter calls
upon the termination clause stipulated in article 18 the F.o.n. shall be made
available under the conditions of the present Convention without any
prefinancing discount, R1 being payable as of the first year of the availability
of the F.o.n. In this case, the downpayment made to the SANEF as prefinancing
under article 14.3.1 of the Convention shall be applied to the amount of the
said invoice.

                                                                              37

In exchange for the prefinancing, and subject to full payment thereof by June
20, 1997, the OPERATOR shall benefit for the duration of the present Convention
from an exceptional discount on the R1 fee that will vary in the following
proportions depending on the date of payment of P:

## MATERIAL OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL
TREATMENT ##, in which J represents the number of calendar days between the
payment date and January 30, 1997."

Article 3

The second sentence of the second paragraph of article 9.1.2 is modified as
follows:

"However, the penalties as a whole are subject to a ceiling of ## MATERIAL
OMITTED AND SEPARATELY FILED UNDER A REQUEST FOR CONFIDENTIAL TREATMENT ## of
the amount of the prefinancing mentioned in article 14.3, and the penalties
shall be suspended for the first seven days."

LADIES AND GENTLEMEN:

         Subject to the terms of the Exchange Offer, the undersigned hereby
tenders to the Company the principal amount of Outstanding Notes indicated
above.  Subject to and effective upon the acceptance for exchange of the
principal amount of Outstanding Notes tendered in accordance with this Letter
of Transmittal, the undersigned sells, assigns and transfers to, or upon the
order of, the Company all right, title and interest in and to the Outstanding
Notes tendered hereby.  The undersigned hereby irrevocably constitutes and
appoints the Exchange Agent its agent and attorney-in-fact (with full knowledge
that the Exchange Agent also acts as the agent of the Company and as Trustee
under the Indenture for the Outstanding Notes and the Exchange Notes) with
respect to the tendered Outstanding Notes with full power of substitution to
(i) deliver certificates for such Outstanding Notes to the Company, or transfer
ownership of such Outstanding Notes on the account books maintained by DTC,
together, in either such case, with all accompanying evidences of transfer and
authenticity to, or upon the order of, the Company and (ii) present such
Outstanding Notes for transfer on the books of the Company and receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Outstanding Notes, all in accordance with the terms of the Exchange Offer.  The
power of attorney granted in this paragraph shall be deemed irrevocable and
coupled with an interest.

         The undersigned hereby represents and warrants that he or she has full
power and authority to tender, sell, assign and transfer the Outstanding Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances
and not subject to any adverse claim, when the same are acquired by the
Company.  The undersigned also acknowledges that this Exchange Offer is being
made in reliance upon an interpretation by the staff of the Securities and
Exchange Commission that the Exchange Notes issued in exchange for the
Outstanding Notes pursuant to the Exchange Offer may be offered for sale,
resold and otherwise transferred by holders thereof (other than any such holder
that is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such Exchange Notes
are acquired in the ordinary course of such holder's business and such holders
have no arrangement with any person to participate in the distribution of such
Exchange Notes.  If the undersigned is not a broker-dealer, the undersigned
represents that it is not engaged in, and does not intend to engage in, a
distribution of the Exchange Notes.  If the undersigned is a broker-dealer that
will receive Exchange Notes from its own account in exchange for Outstanding
Notes, the undersigned represents that such Outstanding Notes were acquired as
a result of market-making activities or other trading activities and
acknowledges that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Notes; however,
by so acknowledging and by delivering a prospectus, the undersigned will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
<PAGE>   7
                                       7

         The undersigned Holder represents that (i) the Exchange Notes acquired
pursuant to the Exchange Offer are being obtained in the ordinary course of
business of the person receiving such Exchange Notes, whether or not such
person is such Holder, (ii) neither the Holder of Outstanding Notes nor any
other person has an arrangement or understanding with any person to participate
in the distribution of such Exchange Notes, (iii) if the Holder is not a
broker-dealer, or is a broker-dealer but will not receive Exchange Notes for
its own account in exchange for Outstanding Notes, neither the Holder nor any
such other person is engaged in or intends to participate in the distribution
of such Exchange Notes and (iv) neither the Holder nor any such other person is
an "affiliate" of the Company within the meaning of Rule 405 of the Securities
Act or, if such Holder is an affiliate, that such Holder will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable.

         The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the assignment and transfer of the Outstanding Notes
tendered hereby.

         For purposes of the Exchange Offer, the Company shall be deemed to
have accepted validly tendered Outstanding Notes when, as and if the Company
has given oral or written notice thereof to the Exchange Agent and complied
with the applicable provisions of the Registration Rights Agreement.  If any
tendered Outstanding Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason or if Outstanding Notes are submitted for a
greater principal amount than the holder desires to exchange, such unaccepted
or non-exchanged Outstanding Notes will be returned without expense to the
tendering Holder thereof (or, in the case of Outstanding Notes tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry
Transfer Facility pursuant to the book-entry transfer procedures described in
the Prospectus under "Terms of the Exchange Offer--Book-Entry Transfer," such
non-exchanged Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration
or termination of the Exchange Offer.

         All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned and every obligation under this Letter of Transmittal shall be
binding upon the undersigned's heirs, personal representatives, successors and
assigns.

         The undersigned understands that tenders of Outstanding Notes pursuant
to the procedures described under the caption "Terms of the Exchange
Offer--Procedures for Tendering" in the Prospectus and in the instructions
hereto will constitute a binding agreement between the undersigned and the
Company upon the terms and subject to the conditions of the Exchange Offer.

         Unless otherwise indicated under "Special Issuance Instructions,"
please issue the certificates representing the Exchange Notes issued in
exchange for the Outstanding Notes

accepted for exchange and return any Outstanding Notes not tendered or not
exchanged, in the name(s) of the undersigned (or in either such event in the
case of Outstanding Notes tendered by DTC, by credit to the account at DTC).
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please send the certificates representing the Exchange Notes issued in exchange
for the Outstanding Notes accepted for exchange and any certificates for
Outstanding Notes not tendered or not exchanged (and accompanying documents, as
appropriate) to the undersigned at the address shown below the undersigned's
signatures, unless, in either event, tender is being made through DTC.  In the
event that both "Special Issuance Instructions" and "Special Delivery
Instructions" are completed, please issue the certificates representing the
Exchange Notes issued in exchange for the Outstanding Notes accepted for
exchange and return any Outstanding Notes not tendered or not exchanged in the
name(s) of, and send said certificates to, the person(s) so indicated.  The
undersigned recognizes that the Company has no obligation pursuant to the
"Special Issuance Instructions" and "Special Delivery Instructions" to transfer
any Outstanding Notes from the name of the registered holder(s) thereof if the
Company does not accept for exchange any of the Outstanding Notes so tendered.

                                  INSTRUCTIONS

                    FORMING PART OF THE TERMS AND CONDITIONS
                   OF THE EXCHANGE OFFER AND THE SOLICITATION

    1.       DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES.  The
certificates for the tendered Outstanding Notes (or a confirmation of a
book-entry into the Exchange Agent's account at DTC of all Outstanding Notes
delivered electronically), as well as a properly completed and duly executed
copy of this Letter of Transmittal or facsimile hereof and any other documents
required by this Letter of Transmittal must be received by the Exchange Agent
at its address set forth herein prior to 5:00 P.M., New York City time, on the
Expiration Date.  The method of delivery of the tendered Outstanding Notes,
this Letter of Transmittal and all other required documents to the Exchange
Agent are at the election and risk of the Holder and, except as otherwise
provided below, the delivery will be deemed made only when actually received by
the Exchange Agent.  Instead of delivery by mail, it is recommended that the
Holder use an overnight or hand delivery service.  In all cases, sufficient
time should be allowed to assure timely delivery.  No Letter of Transmittal or
Outstanding Notes should be sent to the Company.

      Holders who wish to tender their Outstanding Notes and (i) whose
Outstanding Notes are not immediately available or (ii) who cannot deliver
their Outstanding Notes, this Letter of Transmittal or any other documents
required hereby to the Exchange Agent prior to the Expiration Date, or who
cannot complete the procedure for book-entry transfer on a timely basis must
tender their Outstanding Notes and follow the guaranteed delivery procedures
set forth in the Prospectus.  Pursuant to such procedures:  (i) such tender
must be made by or through an Eligible Institution (as defined below); (ii)
prior to the Expiration Date, the Exchange Agent must have received from the
Eligible Institution a properly completed and duly executed Notice of
Guaranteed Delivery (by facsimile transmission, mail or hand delivery) setting
forth the name and address of the Holder of the Outstanding Notes, the
certificate number or numbers of such Outstanding Notes and the principal
amount of Outstanding Notes tendered, stating that the tender is being made
thereby and guaranteeing that within three New York Stock Exchange trading days
after the Expiration Date, this Letter of Transmittal (or copy thereof)
together with the certificate(s) representing the Outstanding Notes (or a
confirmation of electronic mail delivery of book-entry delivery into the
Exchange Agent's account at DTC) and any of the required documents will be
deposited by the Eligible Institution with the Exchange Agent; and (iii) such
properly completed and executed Letter of Transmittal (or copy thereof), as
well as all other documents required by this Letter of Transmittal and the
certificate(s) representing all tendered Outstanding Notes in proper form for
transfer (or a confirmation of electronic mail delivery of book-entry delivery
into the Exchange Agent's account at DTC), must be received by the Exchange
Agent within three New York Stock Exchange trading days after the Expiration
Date, all as provided in the Prospectus under the caption "Terms of the
Exchange Offer--Guaranteed Delivery Procedures." Any Holder of Outstanding
Notes who wishes to tender his Outstanding Notes pursuant to the guaranteed
delivery procedures described above
<PAGE>   16
                                      16

must ensure that the Exchange Agent receives the Notice of Guaranteed Delivery
prior to 5:00 P.M., New York City time, on the Expiration Date.

      All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Outstanding Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding.  The Company reserves the absolute right to reject any and
all Outstanding Notes not properly tendered or any Outstanding Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful.  The Company also reserves the absolute right to waive any
defects, irregularities or conditions of tender as to particular Outstanding
Notes.  The Company's interpretation of the terms and conditions of the
Exchange Offer (including the instructions in this Letter of Transmittal) will
be final and binding on all parties.  Unless waived, any defects or
irregularities in connection with tenders of Outstanding Notes must be cured
within such time as the Company shall determine.  Although the Company intends
to notify Holders of defects or irregularities with respect to tenders of
Outstanding Notes, neither the Company, the Exchange Agent nor any other person
shall be under any duty to give notification of defects or irregularities with
respect to tenders of Outstanding Notes, nor shall any of them incur any
liability for failure to give such notification.  Tenders of Outstanding Notes
will not be deemed to have been made until such defects or irregularities have
been cured or waived.  Any Outstanding Notes received by the Exchange Agent
that are not properly tendered and as to which the defects or irregularities
have not been cured or waived will be returned without cost by the Exchange
Agent to the tendering Holders of Outstanding Notes, unless otherwise provided
in this Letter of Transmittal, as soon as practicable following the Expiration
Date.

    2.       PARTIAL TENDERS.  Tenders of Outstanding Notes will be accepted
only in authorized denominations of $1,000.  If less than the entire principal
amount of any Outstanding Notes is tendered,  the tendering Holder should fill
in the principal amount tendered in the third column of the chart entitled
"Description of Outstanding Notes."  The entire principal amount of Outstanding
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.  If the entire principal amount of all Outstanding
Notes is not tendered, Outstanding Notes for the principal amount of
Outstanding Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.  If the entire principal amount of all
Outstanding Notes is not tendered, Outstanding Notes for the principal amount
of Outstanding Notes not tendered and a certificate or certificates
representing Exchange Notes issued in exchange of any Outstanding Notes
accepted will be sent to the Holder at his or her registered address, unless a
different address is provided in the appropriate box on this Letter of
Transmittal or unless tender is made through DTC, promptly after the
Outstanding Notes are accepted for exchange.

    3.       SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND
ENDORSEMENTS; GUARANTEE OF SIGNATURES.  If this Letter of Transmittal (or copy
hereof) is signed by the registered Holder(s) of the Outstanding Notes tendered
hereby, the signature must correspond
<PAGE>   17
                                       17

with the name(s) as written on the face of the Outstanding Notes without
alteration, enlargement or any change whatsoever.

      If this Letter of Transmittal (or copy hereof) is signed by the
registered Holder(s) of Outstanding Notes tendered and the certificate(s) for
Exchange Notes issued in exchange therefor is to be issued (or any untendered
principal amount of Outstanding Notes is to be reissued) to the registered
Holder, such Holder need not and should not endorse any tendered Outstanding
Note, nor provide a separate bond power.  In any other case, such holder must
either properly endorse the Outstanding Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal, with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.

    If this Letter of Transmittal (or copy hereof) is signed by a person other
than the registered Holder(s) of Outstanding Notes listed therein, such
Outstanding Notes must be endorsed or accompanied by properly completed bond
powers which authorize such person to tender the Outstanding Notes on behalf of
the registered Holder, in either case signed as the name of the registered
Holder or Holders appears on the Outstanding Notes.

      If this Letter of Transmittal (or copy hereof) or any Outstanding Notes
or bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of corporations or others acting in a fiduciary
or representative capacity, such persons should so indicate when signing, and
unless waived by the Company, evidence satisfactory to the Company of their
authority to so act must be submitted with this Letter of Transmittal.

      Endorsements on Outstanding Notes or signatures on bond powers required
by this Instruction 3 must be guaranteed by an Eligible Institution.

      Signatures on this Letter of Transmittal (or copy hereof) or a notice of
withdrawal, as the case may be, must be guaranteed by a member firm of a
registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office
or correspondent in the United States or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible
Institution") unless the Outstanding Notes tendered pursuant thereto are
tendered (i) by a registered Holder (including any participant in DTC whose
name appears on a security position listing as the owner of Outstanding Notes)
who has not completed the box set forth herein entitled "Special Issuance
Instructions" or "Special Delivery Instructions" of this Letter of Transmittal
or (ii) for the account of an Eligible Institution.

    4.       SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering Holders
should indicate, in the applicable spaces, the name and address to which
Exchange Notes or substitute Outstanding Notes for principal amounts not
tendered or not accepted for exchange are to be issued or sent, if different
from the name and address of the person signing this Letter of Transmittal (or
in the
<PAGE>   18
                                       18

case of tender of the Outstanding Notes through DTC, if different from the
account maintained at DTC indicated above).  In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.

    5.       TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the exchange of Outstanding Notes pursuant to the Exchange Offer.
If, however, certificates representing Exchange Notes or Outstanding Notes for
principal amounts not tendered or accepted for exchange are to be delivered to,
or are to be registered or issued in the name of, any person other than the
registered Holder of the Outstanding Notes tendered hereby, or if tendered
Outstanding Notes are registered in the name of any person other than the
person signing this Letter of Transmittal, or if a transfer tax is imposed for
any reason other than the exchange of Outstanding Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered Holder or any other person) will be payable by the tendering
Holder.  If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with this Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering Holder.

      Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the Outstanding Notes listed in this
Letter of Transmittal.

    6.       WAIVER OF CONDITIONS.  The Company reserves the absolute right to
amend, waive or modify specified conditions in the Exchange Offer in the case
of any Outstanding Notes tendered.

    7.       MUTILATED, LOST, STOLEN OR DESTROYED OUTSTANDING NOTES.  Any
tendering Holder whose Outstanding Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated herein for
further instruction.

    8.       REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and
requests for assistance and requests for additional copies of the Prospectus or
this Letter of Transmittal may be directed to the Exchange Agent at the address
specified in the Prospectus.  Holders may also contact their broker, dealer,
commercial bank, trust company or other nominee for assistance concerning the
Exchange Offer.

    9.       IRREGULARITIES.  All questions as to the validity, form,
eligibility (including time of receipt), and acceptance of Letters of
Transmittal or Outstanding Notes will be resolved by the Company, whose
determination will be final and binding.  The Company reserves the absolute
right to reject any or all Letters of Transmittal or tenders that are not in
proper form or the acceptance of which would, in the opinion of the Company's
counsel, be unlawful.  The Company also reserves the absolute right to waive
any irregularities or conditions of tender as to the particular Outstanding
Notes covered by any Letter of Transmittal or tendered pursuant to such Letter
of Transmittal.  None of the Company, the Exchange Agent or any other person
<PAGE>   19
                                       19

will be under any duty to give notification of any defects or irregularities in
tenders or incur any liability for failure to give any such notification.  The
Company's interpretation of the terms and conditions of the Exchange Offer
shall be final and binding.

    IMPORTANT:  THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER
WITH CERTIFICATES FOR OUTSTANDING NOTES AND ALL OTHER REQUIRED DOCUMENTS) OR A
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR
PRIOR TO 5:00 P.M., NEW YORK CITY TIME ON THE EXPIRATION DATE.
