                         11 1/2% SENIOR NOTES DUE 2007
                                      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 (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 June 30, 1997, on a pro forma basis, the Company would have had no
Indebtedness other than the Outstanding Notes, and the Company's subsidiaries
would have had $10.0 million of total liabilities reflected on the Company's
balance sheet. 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

  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.

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
SURRENDERS OF OR EXCHANGE FROM, HOLDERS OF OUTSTANDING NOTES IN ANY JURISDICTION

    NO DEALER, SALESPERSON OR OTHER INDIVIDUAL HAS BEEN AUTHORIZED TO GIVE ANY
INFORMATION OR MAKE ANY REPRESENTATION NOT CONTAINED IN THIS PROSPECTUS IN
CONNECTION WITH THE OFFERING COVERED BY THIS PROSPECTUS. IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED

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

                             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. 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 or
relitigation on 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,
and its telephone number is 32-2-658-5200.
 
                              CERTAIN DEFINITIONS
 
     As used in this Prospectus, "H.E.R." or the "Company" means Hermes Europe
Railtel B.V., a Netherlands corporation. References to "guilders" or "NLG" are

                                  THE COMPANY
 
     Hermes Europe Railtel B.V. is developing an approximately 17,000 kilometer,
pan-European high capacity fiber optic network (the "H.E.R. Network" or the
"Network") designed to interconnect a majority of the largest Western and
Central European cities. H.E.R.'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"). H.E.R. 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.
 
     H.E.R. 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") through April 1998. The initial five country network is
expected to consist of 2,600 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 H.E.R. Network is expected to have points of presence in at
least 32 cities in 15 European countries (the "H.E.R. Geographical Area" or
"HERGA"). H.E.R. 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 H.E.R. 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
<PAGE>   8
 
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 H.E.R.
Network will provide the following advantages: the Network will (i) be wholly
controlled and operated by H.E.R., 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 should be 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 are currently being negotiated with respect to the portion of
the Network connecting Germany with each of France, the Netherlands and
Switzerland. The Company has also entered into an agreement with two utility
companies to
 
                                        2

develop portions of the Network in Germany and expects that Dusseldorf,
Frankfurt and Stuttgart will be connected to the Network by April 1998. In
addition, the Company will be provided transport services between Stockholm and
Copenhagen pursuant to an agreement.
 
     Currently, nine customers are under contract for service on the H.E.R.
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 a reseller.
 
     The H.E.R. 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
H.E.R. 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
H.E.R. 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.
 
     Pro forma for the H.E.R. Recapitalization (as defined), the Company will
have had $102.4 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 H.E.R. 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 June
30, 1997, approximately $22.6 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. Sources of capital to fund Network development after 1998 may
include internally generated funds, bank debt and vendor financing.
 
     H.E.R. 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."

                                         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
                                         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 any 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
                                         June 30, 1997 on a pro forma basis, the
                                         Company would have had no Indebtedness
                                         other than the Notes, and the Company's
                                         subsidiaries would have had $10.0
                                         million of total liabilities reflected
                                         on the Company's balance sheet.
                                         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."

                                         Notes to acquire the Pledged
                                         Securities. The Pledged Securities have

                                         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

                                         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."

                                         in whole or in part, at the option of
                                         the Company, at any time on or after

                                         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.
(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.
(4) Adjusted to reflect the H.E.R. Recapitalization and the Offering.

                                  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 H.E.R. 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,
H.E.R. 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 H.E.R. 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").
 
     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 giving pro forma effect to the
H.E.R. Recapitalization and the Offering and the estimated application of the
proceeds thereof, at June 30, 1997, the Company would have had total long-term
debt of $265.4 million and total shareholders' equity of $68.8 million. The
Company had negative EBITDA of $15.7 million and $8.6 million for the year ended
December 31, 1996 and for the six months ended June 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. The Company
expects to incur substantial additional indebtedness in the future.
 
     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 H.E.R. 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.
 
     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
 
                                       11
<PAGE>   18
 
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 H.E.R. 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 H.E.R. 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 June 30, 1997, approximately $22.6 million has been
spent on Network capital expenditures. After giving pro forma effect to the
Offering and the completion of the H.E.R. Recapitalization, H.E.R. has cash of
$240.5 million available for operations and to construct and develop the
Network. Additional financing will be required to develop the Network. 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 H.E.R.
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 H.E.R. 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
 
     H.E.R. is a development stage enterprise. 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 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 June 30, 1997, the Company had a
cumulative net loss of $32.7 million and a negative working capital balance of
$6.7 million. The Company's negative working capital balance limits its cash
resources, resulting in reduced liquidity. There can
 
                                       12
<PAGE>   19
 
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."
 
     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 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
 
                                       13
<PAGE>   20
 
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 H.E.R.
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
H.E.R. 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
H.E.R. Network, which could have a material adverse effect on the Company's
business.
 
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
 
                                       14
<PAGE>   21
 
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 H.E.R. 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.
 
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 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
 
                                       15
<PAGE>   22
 
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
 
     H.E.R. 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 H.E.R.'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 H.E.R. 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 H.E.R.
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 equipment are introduced. Failure to achieve
current specifications for, or future upgrades of, the Network may materially
and adversely affect the viability of the H.E.R. 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
 
                                       16
<PAGE>   23
 
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 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."

                                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 $251.5 million. The net proceeds of the Offering
will be used, together with the $51.1 million equity contribution from
GTS-Hermes (described below), to complete the development and operational
start-up of the initial five country network and for general working capital
purposes. As of June 30, 1997, the Company has spent approximately $22.6 million
on Network capital expenditures. The Company's sources of liquidity through the
end of June 1997 have been capital contributions totaling $2.9 million in the
form of common equity and shareholder loans totaling $48.4 million, which were
converted into common equity upon the finalization of the H.E.R.
Recapitalization. Additional cash proceeds of approximately $51.1 million were
contributed (the "GTS Contribution") as common equity, on September 30, 1997, by
GTS-Hermes pursuant to the H.E.R. 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.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to 5:00 p.m., New York time, on the Expiration Date.
 
     For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent at the address set forth below under "Exchange
Agent." Any such notice of withdrawal must specify the name of the person having
tendered the Outstanding Notes to be withdrawn, identify the Outstanding Notes
to be withdrawn (including the principal amount of such Outstanding Notes), and
(where certificates for Outstanding Notes have been transmitted) specify the
name in which such Outstanding Notes were registered, if different from that of
the withdrawing holder. If certificates for Outstanding Notes have been
delivered or otherwise identified to the Exchange Agent, then, prior to the
release of such certificates, the withdrawing holder must also submit the serial
numbers of the particular certificates to be withdrawn and a signed notice of
withdrawal with signatures guaranteed by an Eligible Institution unless such
holder is an Eligible Institution. If Outstanding Notes have been tendered

                      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 June 30, 1997 and 1996, December 31, 1996, 1995
and 1994 and for the three and six months ended June 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
 
  THREE AND SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO THREE AND SIX MONTHS
ENDED JUNE 30, 1996
 
     Revenue.  For the three months and six months ended June 30, 1997, the
Company generated revenue of $0.4 million and $0.6 million, respectively. This
revenue was generated from the operation of the Brussels to Amsterdam segment of
the H.E.R. Network, which began commercial operation in November 1996. There was
no revenue generated from operations for the three and six months ended June 30,
1996, respectively.
 
     Gross Margin.  The Company had gross margins of $(1.1) million in both the
three months ended June 30, 1997 and 1996, respectively and $(2.7) million and
$(2.3) million for the six months ended June 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 $3.7 million and $2.2 million for the three months ended June 30,
1997 and 1996, respectively, and $6.3 million and $4.7 million for the six
months ended June 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 115 and 74 employees at June 30, 1997 and
1996, respectively.
 
     Foreign Currency.  H.E.R. experienced foreign currency losses of $0.7
million and $0.3 million for the three months ended June 30, 1997 and 1996,
respectively, and $0.4 million and $0.5 million for the six months ended June
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.  H.E.R. had minimal revenues for the year ended December 31, 1996
and no revenues for the years ended December 31, 1995 and 1994.
 
     Gross Margin.  H.E.R. 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.
 
                                       29
<PAGE>   36
 
     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, 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
H.E.R.'s continued transition from the start-up phase to the operational phase.
 
     Foreign Currency.  H.E.R. 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 H.E.R. through June 30, 1997 has been
equity contributions of $2.9 million and shareholder loans of $48.4 million, all
of which have been converted by September 1997. Additional cash proceeds of
approximately $51.1 million have been contributed by GTS-Hermes.
 
     Development of the H.E.R. 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.
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 a negative working
capital balance of $0.4 million, $4.4 million and $6.7 million as of December
31, 1995, December 31, 1996, and June 30, 1997, respectively. The Company had an
accumulated deficit of $32.7 million at June 1997 including net losses of
approximately $16.0 million and $10.0 million for the periods ending December
31, 1996 and June 30, 1997, respectively.
 
  LIQUIDITY ANALYSIS
 
     The Company had cash and cash equivalents of $1.1 million and $2.0 million

                               INDUSTRY OVERVIEW
 
     H.E.R.'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.
H.E.R. 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 H.E.R. 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 H.E.R., 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 H.E.R. 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.
 
H.E.R. 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. H.E.R. 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 H.E.R. 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 H.E.R. 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 H.E.R.
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 H.E.R. 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 H.E.R. Network.
 
     Non-facilities based carriers.  The Company expects that non-facilities
based carriers will be interested in using the H.E.R. Network because the
Network will offer high quality service at lower prices than currently offered
by PTOs. In addition, for Internet backbone networks, H.E.R. offers advanced
technology and is capable of handling large volumes of traffic. For all
customers, H.E.R. 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 H.E.R. 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 H.E.R. 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
 
     H.E.R.'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. H.E.R.
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 H.E.R. Network is dependent upon,
among other things, H.E.R.'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 H.E.R. Network
Roll-out."
 
     H.E.R. is developing an approximately 17,000 kilometer, pan-European high
capacity fiber optic network designed to interconnect a majority of the largest
Western and Central European cities. H.E.R. 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 17,000 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.
H.E.R. 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. H.E.R. 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 through April
1998. The initial five country network is expected to consist of 2,600
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, 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
H.E.R. Network is expected to have points of presence in at least 32 cities in
15 European countries.
 
     H.E.R. 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 should be placed in commercial service
in January 1998. In France, H.E.R. 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 are currently being negotiated with respect to the portion of
the Network connecting Germany with each of France, the Netherlands and
Switzerland. The Company has also entered into an agreement with two utility
companies to develop portions of the Network in Germany and expects that
Dusseldorf, Frankfurt and Stuttgart will be connected to the Network by April
1998. In addition, H.E.R. will be provided transport services between Stockholm
and Copenhagen pursuant to an agreement.
 
     H.E.R. 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 H.E.R. 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 H.E.R.
Network Roll-out."
 
     H.E.R. 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
 
                                       35
<PAGE>   42
 
communications network for railway traffic. GTS-Hermes purchased a 34.4%
interest in H.E.R. in 1994 and has increased its interest to 50% in 1995 and to
79% in 1997. GTS-Hermes is a wholly owned subsidiary of GTS.
 
BUSINESS AND MARKETING STRATEGY
 
     The overall strategy of H.E.R. 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 H.E.R.
Network also provides a vehicle through which a carrier can compete in other
markets where the carrier does not own infrastructure. H.E.R. expects to enter
the market ahead of competition and encourage a wide variety of carriers to use
its Network with service offerings that meet their needs. H.E.R.'s primary
service offerings are large-capacity circuits for "wholesale" customers such as
PTOs and New Entrants. H.E.R. does not intend to market its services to retail
end-user customers such as corporations. H.E.R.'s focus on carriers is designed
to complement and not compete with carriers' own business objectives in
providing services to end-users.
 
     To establish H.E.R. as the leading carriers' carrier for international
telecommunications within Europe, H.E.R. 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 H.E.R. 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 H.E.R. 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 H.E.R. Network's
     uniform technology enhances service by providing quality and reliability as
     well as uniformity of features throughout the Network.
 
          Diverse Routing.  The H.E.R. 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 H.E.R. Network, the Company believes that
     carrier customers would need to purchase additional dedicated circuits to
     provide for redundancy.
 
          Rapid Provisioning.  H.E.R. services provide access to the Network,
     such that additional capacity can be provided to customers on the H.E.R.
     Network on a rapid basis. This access provides a level of capabilities that
     the Company believes is unavailable in Western Europe today.
 
          Flexibility.  H.E.R. 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.  H.E.R. 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. H.E.R. intends to offer competitive
     pricing. H.E.R. 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

<PAGE>   43
 
     from PTOs are generally limited to order from a very narrow set of
     capabilities offered under inflexible pricing plans.
 
     Although H.E.R. 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, H.E.R.'s
Western European strategy calls for it to focus on carriers' carrier services,
so that it will not compete with its carrier customers in consumer or corporate
markets. H.E.R. 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
 
     H.E.R.'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.
H.E.R.'s service is not intended for business or residential end users. The
H.E.R. 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.
 
     H.E.R. 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. Currently, H.E.R. is providing one structured service
offering (Point-to-Point Transport Service) on its Brussels-Amsterdam link and
an additional service offering (Virtual Infrastructure) will be available upon
completion of the Brussels-Amsterdam-London ring of the initial five country
network.
 
     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 H.E.R.'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 H.E.R. "Integrated" service provides an end-to-end service
between customer-specified locations where the customer can request for H.E.R.
to arrange for "last mile" services from the H.E.R. node location to the
customer's location. The H.E.R. "Node-to-Node" service can be selected only
where the customer provides its own services to reach the local H.E.R. node
location. In Node-to-Node Service, H.E.R. guarantees service only on its portion
of the Network between H.E.R. nodes. Both services will be 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 H.E.R. 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 European
cross-border 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
 
                                       37
<PAGE>   44
 
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.
 
     H.E.R.'s Virtual Infrastructure Service will offer a new solution and an
attractive alternative to leasing IPLCs or building infrastructure. This service
will enable H.E.R.'s customers to obtain a uniform pan-European or cross-border
network under one service agreement by allowing the customer to select any
number of cities along the H.E.R. 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 reconfigure or shift capacity among the customer's leased channels,
thereby enabling the customers to respond almost immediately to changes in
traffic. By being able to transfer capacity among the Network routes, H.E.R.'s
customers are able to avoid the risks of 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 H.E.R. Network Operations Center. This remote
Network management ability is inherent in SDH technology and allows rapid
provisioning and high quality of service.
 
     Sales and marketing of H.E.R.'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
 
     H.E.R.'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. H.E.R. will target seven major market segments or
customer groups which can be characterized as follows:
 
                                       38
<PAGE>   45
 
          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 H.E.R. 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 H.E.R. 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. H.E.R. 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 H.E.R.
     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 H.E.R.
 
          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. H.E.R. believes that it provides an attractive alternative at
     better pricing in those environments where such a consortium does not
     already own its infrastructure. Furthermore, H.E.R. 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. H.E.R. 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 H.E.R. 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. H.E.R. will allow them to meet 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
 
                                       39
<PAGE>   46
 
emerging broad band applications such as cable TV programming distribution
(other than broadcast) to the end user.
 
CURRENT OPERATIONS
 
     H.E.R. is currently operating the network on the Brussels-Amsterdam link
with additional access points in Antwerp and Rotterdam. H.E.R. began initial
trials of this 244 kilometer portion of the Network 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 nine customers are
under contract for service on the H.E.R. Network, including PTOs, a global
consortium of PTOs, Internet service providers, an international carrier, a VAN
and a reseller. H.E.R. provided capacity of approximately 30 E1 equivalent
circuits as of July 30, 1997.
 
     The Brussels-Amsterdam route is a relatively small part of the initial five
country network and is only a point-to-point link that does not provide the
automated redundancy and access of a complete ring network. The route does have
a spare backup fiber pair on key segments to enhance customer reliability. The
type and quality of H.E.R.'s customers validates the concept of the H.E.R.
Network, and illustrates the type of customers who will be attracted to the full
Network. The success of this link 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 H.E.R. 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. H.E.R. uses a
single vendor for the supply of transmission equipment and network management
systems. H.E.R.'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.
 
     H.E.R. 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 of building large quantities of capacity before they can be used.
Where H.E.R. leases dark fiber, the infrastructure provider will generally be
responsible for maintaining such fiber optic cable. H.E.R. has concluded an
agreement with Alcatel to supply equipment. H.E.R. will enter into agreements
with Alcatel and
 
                                       40
<PAGE>   47
 
infrastructure providers and other third parties to maintain the equipment for
the H.E.R. Network. See "Risk Factors -- Risks Relating to H.E.R. Network
Roll-out."
 
     Network Capacity.  The Network will consist of SDH STM-16 links delivered
over fiber owned by H.E.R. and dark fiber leased from infrastructure providers.
Each line system and multiplexer works initially at the 2.5 Gbps (STM-16) level.
Systems with higher bit rates (STM-64) are planned for introduction after 1999.
The most important types of equipment used or to be used in the Network are
Alcatel 1661 SM-C ADM nodes used as Add-Drop Multiplexors ("ADMs") and
regulators and a variety of optical amplifiers for boosting optical signals. The
Company expects to size the 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
WDM technology to multiply the then-existing Network capacity without adding
fiber optic cable.
 
     Network Agreements.  The Company has entered into agreements and letters of
intent with various infrastructure providers for construction and/or lease of
portions of the H.E.R. 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 H.E.R. The term of a
lease agreement typically ranges from 10 to 15 years. An agreement typically
contains optical specification standards for the fiber and methods of testing.
H.E.R. 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 H.E.R. access to such facilities.
Access arrangements to the nodes are also provided so that connection may be
made to H.E.R. 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 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 H.E.R. 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
H.E.R. Network. In each city, as an H.E.R. POP is deployed, H.E.R. may contract
with a local access network supplier for"last mile" services to customer
locations. H.E.R. 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, H.E.R. has contracted to connect the H.E.R. Network to
intra-city networks in those cities. Pursuant to this agreement, H.E.R. can
offer its carrier customers local connectivity in those cities. Local access
network suppliers may also be interested in H.E.R. for the purpose of linking
the business centers in which they are active. Therefore, the Company believes
that the
 
                                       41
<PAGE>   48
 
relationships between H.E.R. and local access network suppliers can benefit both
parties. Set forth below is an illustration of the connection between the H.E.R.
Network and local access providers.

     The Amsterdam-London, Brussels-London, Paris-Brussels and Paris-Strasbourg
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) H.E.R. has contracted to build or is
contracting to build the fiber optic cable segment or (ii) H.E.R. has leased or
will lease such segment of fiber optic cable from a third party who has built or
is currently building such segment. For each of the Frankfurt-Dusseldorf and
Dusseldorf-Amsterdam routes, H.E.R. is currently negotiating construction and/or
lease contracts. For the Strasbourg-Frankfurt route, H.E.R. is negotiating
construction and/or lease contracts for some segments of the route and has some
segments of the route under construction. The dates set forth above
 
                                       42

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 H.E.R. Network
Roll-Out."
 
     H.E.R. 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. H.E.R. 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, H.E.R. 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
H.E.R. 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. H.E.R.'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 H.E.R.
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. H.E.R. 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. H.E.R. intends
to focus on these factors and on service innovation as well. H.E.R.'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 H.E.R.'s competitors, many of whom possess greater technical, financial
and other resources than H.E.R., 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 H.E.R.'s business, financial
condition and results of operations. There can be no assurance that H.E.R. 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 H.E.R.
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.
 
     H.E.R. requires licenses, authorizations or registrations in all countries
to operate the Network. There can be no assurance that H.E.R. will be able to
obtain such licenses, authorizations or registrations or that H.E.R.'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
 
                                       43
<PAGE>   50
 
United Kingdom, the Netherlands, Belgium and Germany and a license application
has been filed in France. 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 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 Western European telecommunications industry,
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.
 
     In the specific area of concern to H.E.R., the European Commission is
seeking to establish EU level guidelines for coordinating national regulatory
frameworks to facilitate the development of pan-European networks. 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, H.E.R. 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 telecommunications regulatory
authority, to create a competitive marketplace from which detailed regulation
could eventually be withdrawn. The United Kingdom has already liberalized its
market beyond the requirements of the Full Competition Directive, and most
restrictions on competition have been removed in practice as well as in law. 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 H.E.R. 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 indicated that it
intends to replace the initial licenses with new licenses and that it would not
normally expect to revoke an initial license without replacing it with another
license giving an equivalent authorization. The DTI is currently discussing with
license holders the arrangements to put these new licenses into effect and
although the DTI has indicated that the new licenses are expected to be of 25
years' duration, there can be no certainty that this will be the case or that
the new licenses will not contain terms or conditions unfavorable to the
Company. It is a condition of the license that H.E.R. notify the DTI of certain
changes in its share ownership. In connection therewith, the DTI has been
notified of the H.E.R. Recapitalization.
 
THE NETHERLANDS
 
     On July 1, 1997 the Dutch government abolished the prohibition on the use
of fixed infrastructure for the provision of public voice telephony, thereby
complying with the requirements of the Full Competition Directive six months
ahead of schedule. On August 1, 1996, H.E.R. was granted a license for the
installation, maintenance and use of a fixed telecommunications infrastructure.
H.E.R. is currently operating under its license in the Netherlands on the
Brussels-Amsterdam-route.
 
     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 H.E.R.
 
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. H.E.R. 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. H.E.R. also has authorization to build infrastructure between major
Belgian population centers.
 
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 file applications to extend its license in Germany as appropriate in
order to enable it to operate the remaining portions of the Network in Germany.

<PAGE>   52
 
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. However, since this
regulatory agency was established, no licenses for alternative networks have
been granted. To operate the Network in France, the Company must receive an
authorization from the French Telecommunications Minister. The Company filed its
application for authorization in November 1996 and received from the ART a draft
license in May 1997, which will be the basis for the final license. The Company
has been informed that the ART has approved a recommendation to the French
minister as to the form of the authorization to be granted to H.E.R. and passed
it on to the responsible ministry for finalization. Upon receipt of such
authorization, the Company will be allowed to operate the 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. H.E.R. intends to apply for a license to provide its services
in due course.
 
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. H.E.R. 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. H.E.R. 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. H.E.R. 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.

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
 
                                       47
<PAGE>   54
 
and Related Transactions." Under the new Shareholders Agreement, resolutions of
the Board of Supervisory 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.

     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.

 (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
     13% of this stock is subject to the GTS-Hermes Plan. Generally, one-third
     of the stock options vest on each of the first three anniversaries of the
     date of grant.
 
 (5) These Named Executive Officers participate in the GTS 401(k) plan to which
     GTS contributed the amounts indicated for 1996.
 
 (6) Mr. Caccappolo received a cost of living allowance of $11,200 and resides
     in a Company apartment which the Company pays the equivalent of $17,928 per
     year in rent (converted from Belgian Francs to U.S. Dollars at an exchange
     rate of BF32.0392=$1.00). In addition, the Company provides Mr. Caccappolo
     with the use of a Company car.
 
 (7) Converted from Belgian Francs to U.S. Dollars at an exchange rate of
     BF32.0392=$1.00.
 
 (8) Perquisites and other personal benefits paid to Mr. Magnus and Mr. Shearing
     during fiscal year 1996 were less than the lesser of $50,000 and 10 percent
     of the total of annual salary and bonus reported for the Named Executive
     Officer.
 
 (9) Mr. Rudy received a housing allowance of $16,855 during fiscal year 1996.
     In addition, the Company provides Mr. Rudy with the use of a Company car.
 
(10) This amount represents premiums paid by GTS for $1,000,000 in term life
     insurance for Mr. Loeber and contributions to Mr. Loeber's account by GTS
     under the 401(k) Plan.

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 H.E.R., 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 H.E.R., 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
H.E.R. 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.
 
     H.E.R. intends to establish a stock option plan to replace the GTS-Hermes
Plan for the purpose of incentivizing H.E.R. key employees, in substantially
similar form to the GTS-Hermes Plan. The aggregate number of shares of H.E.R.
stock subject to the proposed plan would be approximately 13% of the total
shares of H.E.R. stock issued and outstanding including options. Grants under
the GTS-Hermes Plan would be converted into grants under the proposed H.E.R.
plan. Upon establishment of such plan, the GTS-Hermes Plan would 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 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
for an initial term ending December 31, 1996. The parties have agreed to extend
the term for an indefinite period of time. Mr. Magnus' initial gross annual
salary was BF4,080,000. He may also receive a yearly performance-based bonus of
up to 30% of his base salary based at the discretion of the Company. Under the
agreement, Mr. Magnus is entitled to the use of a company car. The agreement
also provides that Mr. Magnus shall be granted an option to buy shares under the
GTS-Hermes Plan under a separate stock option agreement.
 
     Mr. Shearing's Company Employment Agreement was entered into by the parties
of November 1, 1995 for an undetermined period of time. Mr. Shearing's initial
annual salary was BF2,800,000, which is net of all tax and social security
contributions. He may also receive a yearly performance-based bonus of up to 10%
of his base salary at the discretion of the Company. Furthermore, beginning in
1996, Mr. Shearing may receive an additional deferred bonus of up to 10% of his
base salary, which will be payable on the third anniversary of the date such
bonus is awarded, provided that Mr. Shearing is still employed by the Company on
December 31, 1998. Mr. Shearing participates in the Company's pension plan and
is provided with a company car.

(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
    Hermes subject to the proposed plan will be approximately 13% of the total
    Ordinary Shares of Hermes issued and outstanding. See "Executive
    Compensation and Other Information -- GTS-Hermes 1994 Stock Option Plan."
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     H.E.R. 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 H.E.R. 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 June 30, 1997, GTS had approximately 23.5
million shares of common stock outstanding and a stockholders' equity of $76.2
million.
 
     H.E.R. 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, H.E.R. 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.
 
H.E.R. RECAPITALIZATION
 
     H.E.R. has completed a recapitalization (the "H.E.R. Recapitalization"),
wherein H.E.R. extended rights to subscribe to additional shares of H.E.R. to
GTS-Hermes, HIT Rail and the eleven railways
 
                                       55
<PAGE>   62
 
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. H.E.R. 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 approximately 79%, HIT Rail owns approximately 13%, SNCB/NMBS owns
approximately 6% and AB Swed Carrier owns approximately 2% of the outstanding
H.E.R. shares. Pursuant to the H.E.R. Recapitalization, H.E.R., 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 H.E.R. 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
H.E.R., 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
H.E.R., (iv) any amendment to the articles of association other than those
pertaining to increases in the authorized capital of H.E.R. or to convert H.E.R.
into an N.V. ("Naamloze Vennootschap") to enable a public listing of shares or
new shares, (v) any amendment to the scope of H.E.R.'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 additional member. 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 that are not
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 other than GTS-Hermes who hold fewer than
6.8% of the issued share capital of H.E.R. 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.
Preemption rights can be exercised for four weeks after the date the notice of
the offer is received by the shareholders.
 
     The Shareholders Agreement provides that 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.

SHAREHOLDER LEASES AND LOANS
 
     The Company currently leases dark fiber and facilities from, and has
entered into a contract to construct portions of the initial five country
network with, Telfort which is a subsidiary of Nederlandse Spoorwegen, a member

Company. The Company has also entered into a contracts with SNCB/NMBS for the
provision of fiber and facilities for portions of the initial five country
network. SNCB/NMBS is a member of HIT Rail and thus an indirect shareholder of
the Company and is also a direct shareholder of H.E.R. As such, it is entitled

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 the HIT Rail
consortium. The loans were converted into equity as part of the H.E.R.
Recapitalization.

                       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 Hermes Europe Railtel B.V. 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.
 
     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 June 30, after giving pro forma effect to the
H.E.R. Recapitalization and the transfer of all or substantially all of the
Company's assets and liabilities (other than the Notes) to Subsidiaries as
described above, the Company's Subsidiaries would have had total liabilities of
$10.0 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

August 15 of the years indicated below:

  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.

<PAGE>   69
 
        (treated as one accounting period) commencing on the Issue Date and

        preceding the date of such Restricted Payment for which consolidated
        financial information of the Company is required to be available, plus
 
             (2) the aggregate net cash proceeds received by the Company either
        (x) as capital contributions to the Company after the Issue Date or (y)

        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

        Payment made after the Issue Date, with respect to any Unrestricted

        the Issue Date in accordance with "-- Designation of Unrestricted
        Subsidiaries," the Company's proportionate interest in an amount equal

        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

     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

defeasance or other acquisition of Subordinated Indebtedness made in exchange
for, or out of the net cash proceeds of, a substantially concurrent issue and

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
issuance or sale, such Restricted Subsidiary would no longer constitute a
Restricted Subsidiary; or (iii) in the case of issuance of Equity Interests by a
non-Wholly Owned Restricted Subsidiary if, after giving effect to such issuance,
the Company maintains its direct or indirect percentage of beneficial and
economic ownership of such non-Wholly Owned Restricted Subsidiary.
 
     Merger, Sale of Assets, etc.  The Company shall not consolidate with or
merge with or into (whether or not the Company is the Surviving Person) any
other Person and the Company shall not, and shall not cause or permit any
Restricted Subsidiary to, sell, convey, assign, transfer, lease or otherwise
dispose of all or substantially all of the property and assets of the Company
and the Restricted Subsidiaries, taken as a whole, to any Person or Persons
(other than any Restricted Subsidiary), in each case, in a single transaction or
series of related transactions, unless: (i) either (x) the Company shall be the
Surviving Person or (y) the Surviving Person (if other than the Company) shall
be a corporation organized and validly existing under the laws of The
Netherlands, the United States of America or any State thereof or the District
of Columbia, and shall, in any such case, expressly assume by a supplemental
indenture, the due and punctual payment of the principal of and interest on the
Notes and the performance and observance of every covenant of the Indenture, the
Escrow Agreement and the Registration Rights Agreement to be performed or
observed on the part of the Company; (ii) immediately after giving effect to
such transaction, no Default shall have occurred and be continuing; and (iii)
immediately after giving effect to such transaction, the Surviving Person (as
the Company) could Incur at least $1.00 of additional Indebtedness under the
first paragraph of "-- Limitation on Incurrence of Indebtedness."
 
     For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all the properties and assets of one or more Restricted
Subsidiaries the Equity Interests of which constitute all or substantially all
the properties and assets of the Company shall be deemed to be the transfer of
all or substantially all the properties and assets of the Company.
 
     In the event of any transaction (other than a lease) described in and
complying with the conditions listed in the first paragraph of this covenant in
which the Company is not the Surviving Person and the Surviving Person is to
assume all the Obligations of the Company under the Notes, the Indenture, the
Escrow Agreement and the Registration Rights Agreement pursuant to a
supplemental indenture, such Surviving Person shall succeed to, and be
substituted for, and may exercise every right and power of, the Company and the
Company shall be discharged from its Obligations under the Notes, the Indenture,
the Escrow Agreement and the Registration Rights Agreement.
 
     Provision of Financial Information.  Whether or not the Company is subject
to Section 13(a) or 15(d) of the Exchange Act, or any successor provision
thereto, the Company shall file with the SEC (if permitted by SEC practice and
applicable law and regulations) the annual reports, quarterly reports and other
documents which the Company would have been required to file with the SEC
pursuant to such Section 13(a) or 15(d) or any successor provision thereto if
the Company were so required, such documents to be filed with the SEC on or
prior to the respective dates (the "Required Filing Dates") by which the Company
would have been required so to file such documents if the Company were so
required; provided, however, that until the Company is subject to Section 13(a)
or Section 15(d) of the Exchange Act or any successor provisions thereto, the

COVENANT OF GTS
 
     GTS has consummated the GTS Contribution. This obligation 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
comply with any of the provisions described under "-- Certain
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
of bankruptcy, insolvency or reorganization affecting the Company or any
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

than to add sections of the Indenture or the Notes subject thereto) or the right

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.

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.

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.

  ADDITIONAL INTEREST
 
     The Company agrees to pay, as liquidated damages, additional interest on
the Notes ("Additional Interest") under the circumstances and to the extent set
forth below (each of which shall be given independent effect):
 
          (i) if either the Registration Statement or the Initial Shelf
     Registration Statement has not been filed on or prior to the Filing 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 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)
of this paragraph) or (3) upon the exchange of Exchange Securities for all Notes
validly tendered and not withdrawn (in the case of clause (iii)(A) of this
paragraph), or upon the effectiveness of the Registration Statement which had
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 H.E.R. 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 H.E.R. 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 H.E.R. or if he/she holds an
option to buy at least 5% in any class of shares in the capital of H.E.R.
 
  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.
 
                                       89
<PAGE>   96
 
  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, 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 -- Additional Amounts."
According to the Treasury
 
                                       90
<PAGE>   97
 
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.

between individual circuits by software, permitting dynamic cross connect of
individual 64 kbps circuits within an E1 line.
 
     Asynchronous Transfer Mode (ATM).  A switching and transmission technology
that is one of a general class of packet technologies that relay traffic by way
of an address contained within the first five bits of a standard fifty-three
bit-long packet or cell. ATM-based packet transport was specifically developed
to allow switching and transmission of mixed voice, data and video at varying
rates. The ATM format can be used by many different information systems,
including LANs.

transmission system; the number of bits that a transmission facility can convey
between a sending location and a receiving location in one second.
 
     Backbone.  The through-portions of a transmission network, as opposed to
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).
 
     Capacity.  Refers to transmission.
 
     Carrier.  A provider of communications transmission services by fiber, wire
or radio.
 
     CCITT.  International Telegraph and Telephone Consultative Committee.

     Competitive Local Telecommunications Provider.  A company that provides its
customers with an alternative to the local telephone company for local transport
of private line, special access and transport of switched access
telecommunications services. Competitive Local Telecommunications Providers are
also referred to in the industry as alternative local telecommunications service
providers (ALTS), Competitive Access Providers (CAPs) and Competitive Local
Exchange Carriers (CLECs).
 
     Dark Fiber.  Fiber that lacks the requisite electronic and optronic
equipment necessary to use the fiber for transmission.

interexchange private line facilities. Enhanced network services also include
applications on such networks, including Internet access and other Internet
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.
 
     Mbps.  Megabits per second, which is a measurement of speed for digital

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

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

                           HERMES EUROPE RAILTEL B.V.
                         (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

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 H.E.R. 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:

     Under Dutch law, the Company is required to pay a 1% capital duty tax on
all issuances of common stock, which will result in the Company paying a capital
duty tax of approximately $0.9 million. The pro forma balance sheet at December
31, 1996 gives effect to the first phase of the Recapitalization as discussed
above.
 
     Additional phases of the Recapitalization are expected to include the
conversion of loans of ECU 5.4 million (approximately $6.1 million) advanced to
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

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (unaudited)
 
NOTE 1:  FINANCIAL PRESENTATION AND DISCLOSURES
 
     In the opinion of management, the accompanying unaudited condensed,
consolidated financial statements of Hermes Europe Railtel B.V. (the "Company")
contain all adjustments (consisting only of normal recurring accruals) necessary
to present fairly the Company's financial position as of December 31, 1996, June
30, 1997 and pro forma at June 30, 1997 (see Note 3, "Subsequent Events and Pro
Forma Adjustments to Balance Sheet"), 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 three and six months ended June 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
developing and operating a managed, seamless, fiber optic, pan-European network,
and providing high quality trans-border transmission services to
telecommunications carriers across Europe.
 
     As of June 30, 1997, 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 various value-added services in markets outside of the United
States. In an effort to increase the equity of the Company by means of the
contribution of fiber optic cable leases and/or cash by its current owners and
individual shareholders of HIT Rail, the Company undertook a recapitalization
(the "Recapitalization") during the first quarter of 1997 which is expected to
be completed by the end of August 1997 (see Note 3, "Subsequent Events and Pro
Forma Adjustments to Balance Sheet").
 
NOTE 2:  RELATED PARTY TRANSACTIONS
 
     The Company received financing through shareholders' loans transactions
provided by HIT Rail and GTS-Hermes and individual members of HIT Rail. The
components of the Company's shareholders' loans are as follows:

NOTE 3:  SUBSEQUENT EVENTS AND PRO FORMA ADJUSTMENTS TO BALANCE SHEET
 
FINANCING TRANSACTION
 
     Subsequent to June 30, 1997, the Company initiated a debt offering that is
expected to raise $265 million through a series of senior notes due August 15,
2007 ("Senior Notes"). The Senior Notes will be general unsecured obligations of
the Company, with interest payable semiannually at a rate of 11.5%.
Approximately $56.5 million of the net proceeds of the offering will be held in
escrow for the first four semi-annual interest payments commencing in 1998. The
offering includes an optional redemption clause that allows the Company to
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
cash proceeds of a public offering that results in gross proceeds of at least
$75 million or in certain other circumstances specified in the indenture for the
Senior Notes, provided, however, that at least two-thirds of the principal
amount of the Senior Notes originally issued remains outstanding after each such
redemption. Pursuant to the covenants in the offering, the Company will be
required to file a registration statement with the Securities Exchange
Commission within 90 days of the closing of the offering.
 
RECAPITALIZATION
 
     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 nine of the members of HIT Rail
have declined to exercise their rights, while GTS-Hermes and two 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 in cash, net of
the Company's outstanding payables to GTS and GTS-Hermes (approximately $5.7
million at June 30, 1997, as reflected in Due to/from affiliated companies on
the balance sheet) by September 30, 1997. The ECU 46.0 million obligation has
been reflected as paid in the pro forma balance sheet. The first phase of the
Recapitalization resulted in the following ownership of the Company.

     In addition, under Dutch law, the Company is required to pay a 1% capital
duty tax on all issuances of common stock, which will result in the Company
paying a capital duty tax of approximately $0.9 million. The pro forma balance
sheet at June 30, 1997 gives effect to the financing transaction and the first
phase of the Recapitalization as discussed above.
 
     The Recapitalization is expected to be completed by the end of August 1997.
Additional phases of the Recapitalization are expected to include the conversion
of loans of ECU 5.4 million (approximately $6.1 million) advanced to the Company
by two of the individual members of HIT Rail, as well as the

ITEM 22.  UNDERTAKINGS.
 
     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.

The person appearing, acting on behalf of HIT RAIL B.V., declared to hereby

                            ARTICLES OF ASSOCIATION:
                                Name and office.

                                                                               2


                                    Capital.
                                   Article 4.

1. The authorized share capital of the Company amounts to two hundred thousand
Dutch guilders (NLG 200,000), and is divided into two hundred (200) shares of a
nominal value of one thousand Dutch guilders (NLG 1,000) each.

2. Shares not yet issued shall only be issued by notarial deed under the
obligation of payment of at least twenty-five per cent (25%) of their nominal
value, at a rate - provided not below par - and on such conditions and dates as
determined by the Board of Supervisory Directors. 

Options on shares still to be issued may only be granted by the Board of
Supervisory Directors.

Payment in foreign currency of shares, to be issued after the incorporation, can
only be made with the approval of the Company.

3. Shareholders shall have a pre-emption right to the shares to be issued and
options on shares to be issued in proportion to the total nominal value of the
shares held by each of them. 

However, individual shareholders shall not have a pre-emption right to shares,
issued to employees of the Company or a group company in virtue of a resolution
of the general meeting or to shares, issued in case of a merger.

4. A pre-emption right is transferable with due observance of the stipulations
of the present Articles of Association regarding the transfer and transition of
shares.

5. Issue of shares with a pre-emption right and the term, during which it may be
exercised, shall be notified in writing by the Company to all shareholders. A
pre-emption right can be exercised during at least four weeks after the day the
notice was sent. 

The Board of Supervisory Directors, or the Board of Managing Directors after
having obtained the approval thereto of the Board of Supervisory Directors,
shall determine when and at which amount additional payment of shares that have
not been paid up in full, shall take place. The Board of Managing Directors
shall inform the shareholders concerned thereof without any delay. If a
shareholder has not complied with his obligation to pay on the shares in time,
he cannot execute the rights to meet and to vote in respect of his shares as
long as he is default, and his right to dividends is deferred.

6. The Board of Managing Directors shall carry out the resolution of the Board
of Supervisory Directors to issue shares with due observance of the law, the
formalities therein mentioned and on the conditions determined by the Board of
Supervisory Directors.

7. If the capital of the Company consists of different classes of shares, the
general meeting may pass a resolution with respect to each class of shares,
aiming at refunding on shares, at exemption from the obligation to pay on
shares, as well as at drawing and/or cancellation of shares with refunding of
the capital paid thereon. 

8. In order to subscribe or acquire shares in its capital or certificates of
beneficial ownership thereof, the Company

                                                                               3


may only grant loans not exceeding the amount of the payable reserves and
provided that the general meeting has granted its approval; the Company shall
then keep a non-payable reserve to the amount of the outstanding loans.

9. The Company shall not cooperate in the issue of depositary receipts of shares
in the Company. 

                                    Shares.

shall be issued in respect of shares.

                                   Article 6.

1. The Board of Managing Directors shall keep a register into which the names of
all the holders of shares are entered together with the nominal amount paid on
every share, and the quantity and the numbers of the shares, held by every
shareholder; as far as shares that have not paid up in full are concerned, each
release from liability for payment not yet made shall be recorded. 

2. The register shall likewise contain the names and addresses of those who have
a right of usufruct or a pledge with regard to such shares, stating to which
rights attached to the shares they are entitled pursuant to paragraphs 8 and 9
of this article.

3. Furthermore, the register shall contain the names and addresses of the
holders of registered certificates of beneficial ownership in respect of shares,
issued with the co-operation of the Company.

4. Every shareholder, usufructuary and pledge and every holder of registered
certificates in respect of shares issued with the co-operation of the Company,
shall have the obligation to take care that his address is known to the Company.

5. The register should be kept up regularly. 

Any entry in the register and any extract, as referred to in paragraph 6, shall
be signed by a managing director.

6. Upon request, the Board of Managing Directors shall provide a shareholder,
usufructuary or pledgee with a free extract from the register concerning his
rights with respect to the shares. 

In case a right of usufruct or a pledge is established on a share, the register
shall indicate who shall be entitled to the rights referred to in paragraphs 8
and 9 of this article.

7. The Board of Managing Directors shall deposit the register at the office of
the Company for inspection by shareholders as well as by usufructuaries and
pledgees entitled to vote and to attend meetings. 

The particulars in respect of shares that have not been paid up in full shall be
available for public inspection; a copy of or an extract from such particulars
shall be provided at cost price.

8. The shares may be encumbered with usufruct and a pledge. The voting right in
respect of the shares shall, however,

                                                                               4


remain vested in the pledgee.

9. The usufructuary and the pledgee shall not have the rights conferred by law
to the holders of depositary receipts of shares issued with the co-operation of
the Company.

10. Rights ensuing from a share and aiming at the acquisition of shares, shall
belong to the shareholder, provided that he shall compensate the usufructuary
for the value thereof as far as the latter is entitled to such compensation
pursuant to his right of usufruct.

                                   Article 7.

If a share is held jointly by more than one person, the Company may require that
the joint holders shall grant one person a written power of attorney to
represent them in their relations to the Company.

               Transfer and transition of shares (Blocking rules).
                                   Article 8.

1. Every transfer of one or more shares by a shareholder may only be effectuated
in the way and with due observance of the provisions of this article and article
9. These provisions need not to be observed, if within a period of two months
after the shareholder who wants to transfer, has requested for the permission,
all shareholders have granted written permission for the transfer and, moreover,
the transfer is effected within three months after the approval has been granted
by all shareholders.

2. A shareholder intending to alienate one or more of his shares shall give
notice thereof to the Board of Managing Directors and to the Board of
Supervisory Directors, which notice shall be considered to be an offer for sale.

3. Within one month after receipt of that notice, the Board of Managing
Directors shall give relevant notice to all shareholders.

4. Within one month after the date of the notice to the shareholders, the
shareholders shall inform the Board of Managing Directors, if they wish to take
over either all the shares offered or part thereof.

5. If shareholders apply for a number of shares exceeding the number that is
available, shares shall be allocated by the Board of Managing Directors as far
as possible in proportion to the total nominal amount of shares held by each
applicant and, insofar proportional distribution is impossible, to several
applicants jointly.

6. As soon as it becomes clear that not all the shares offered are taken over by
other shareholders, the offeror shall have the rights as hereinafter referred to
in paragraph 14.

Without the offeror being bound thereto in whatever way, within three months
after receipt of the notice referred to in paragraph 2 the Board of Managing
Directors may apply for the shares that are not taken over, on behalf of the
Company with due observance of the provisions of article 11. 

If the offeror wishes to accept, he may do so on the condition that the price to
be paid be increased by the additional income tax due he has to pay as compared
with the income tax to be paid in case of a sale to a third party.

                                                                               5


7. Within three months after receipt of the notice referred to in paragraph 2,
the Board of Managing Directors shall inform the offeror whether or not
application was made for the shares and in the affirmative, inform him of the
name(s) of the applicant(s) and the number of shares he/they wish(es) to buy,
while at the same time the Board of Managing Directors shall inform the
applicant(s) of the number or shares, allocated to him/them for the time being,
pursuant to paragraph 5. 

8. The price at which shares are to be transferred shall be fixed by the offeror
and the applicant(s) by common agreement.

If they fail to reach an agreement on the price within one month after the date
of the informing notice referred to in the preceding paragraph, the price shall
be the value of the offered shares as determined by an independent expert, to be
appointed by the Chairman of the Chamber of Commerce and Industry of the
district in which the Company has its principal office, upon request of the most
diligent party.

9. The costs of valuation shall be paid by the Company. 

If the right referred to in the paragraphs 11 or 13 of the present article is
made use of, half of the valuation costs shall be paid by the person who
withdraws.

The Company is obliged to provide the expert(s) with all the data relevant for
the valuation, upon first request and without any delay.

10. The expert shall inform the Board of Managing Directors of his decision.
Within one week after receipt of that decision, the Board of Managing Directors
shall notify the same to the offeror and to the applicant(s).

11. Until one month after the date of that notification, each applicant shall
have the right to withdraw by means of a notice to the Board of Managing
Directors.

In case of withdrawal by an applicant the Board of Managing Directors shall
inform the applicant(s) who has/have not withdrawn, and the offeror thereof
within one week after receipt of the notice referred to above.

After the price of all the shares has been determined by common agreement
respectively after expiry of the term of one month referred to in the present
paragraph, the offeror may demand that each of the applicants, who did not
withdraw, provide security - by means of an irrevocable bank guarantee or
otherwise - for the payment of the purchase price within a reasonable period of
time.

12. In case of withdrawal by an applicant or failure of a purchaser to grant the
security referred to in paragraph 11, the shares that have come out, shall be
offered again to the other applicants at the determined price and in the way
described above, or may also be purchased by the Company in accordance with the
provisions, mentioned in paragraph 6 of this article, be it that (an)
applicant(s) who take(s) up the offer shall no longer be entitled to withdraw
and on the understanding, that it shall not be possible to offer to a
shareholder/buyer in default and/or the person who has withdrawn.

A renewed offer needs not to be made more than once; the
<PAGE>   6

                                                                               6


offeror should be notified thereof by the Board of Managing Directors.

13. The offeror shall always be entitled to withdraw his offer, provided he does
so within one month after having been informed of the applicant(s) to whom he
may transfer all the shares offered and at which price. 

Shares should be transferred within one month after the expiration of the term
within which the offeror may withdraw.

not sufficient applicants or after it appeared that the security referred to
above was not granted within the term fixed.

2. The relevant provisions of article 8 - including paragraph 1 of that article
- - shall be applicable to the offer referred to above and the subsequent

1. Unless the Company acquires shares for no value or under an universal title,
the Company may only acquire fully paid-up shares in its own capital, if the
acquisition has been authorized by the Board of Supervisory Directors and:

a. the shareholders' equity of the Company, decreased with the acquisition
price, is not less than the paid-up and claimed part of the capital, increased
with the reserves to be kept in accordance with the law or the Articles of
Association;

b. the nominal amount of the shares to be acquired and those already held by the
Company and its subsidiaries jointly, amounts to no more than half of the issued

A subsidiary of the Company may not subscribe or cause the subscription for
shares in the Company's capital for its own account. A subsidiary of the Company
may only acquire such shares for its own account and on a particular basis of

shares, held by the Company itself, or of which it has a right of usufruct or a
pledge, or of which it holds depositary receipts.

Such shares shall not be taken into consideration when calculating the
distribution of profits or liquidation balance, unless a right of usufruct or a
pledge has been established on those shares in behalf of another person than the
Company.

The provision of the first sentence of this paragraph is accordingly applicable
to shares or depositary receipts of shares held by subsidiaries of the Company
or on which subsidiaries have a right of usufruct or a pledge.

after refunding of shares drawn by lot after drawing, is possible; resolutions
with respect to cancellation shall be passed in a general meeting of

part of the capital being lower than one/fifth part of the authorized capital or
than the minimal capital prescribed by law at the moment of the resolution.

4. Shares held by the Company itself can only be alienated in the manner
prescribed for issue of shares not yet issued. The articles 8 and 9 do not apply

1. The share capital issued at the incorporation of the Company amounts to forty
thousand Dutch guilders (NLG 40,000).

In the issued share capital the founder HIT RAIL B.V. participates with forty
(40) shares of one thousand Dutch guilders (NLG 1,000) nominal value each.

The shares shall be issued at par and are fully paid up in Dutch currency.

RAIL B.V. is hereby appointed as managing director. Supervisory directors will
be appointed as soon as possible.

3. The first financial year shall end on the thirty-first day of December
nineteen hundred and ninety-three.

annotated on a draft of this deed.

                                   Article 2.

The Company has been established for an indefinite period of time.

                                    Capital.
                                   Article 4.

1.    The authorized share capital of the Company amounts to three hundred five
      thousand Dutch guilders (NLG 305,000), and is divided into three hundred
      and five (305) shares of a nominal value of one thousand Dutch guilders
      (NLG 1,000) each.

2.    Shares not yet issued shall only be issued by notarial deed under the
      obligation of payment of their nominal value in full, at a rate - provided
      not below par - and on such conditions and dates as determined by the
      Board of Supervisory Directors. The pre-emption right may, but only for
      individual issues, be limited or excluded by a unanimous resolution of the
      general meeting representing the entire issued share capital of the
      Company. 

      Payment in foreign currency of shares, to be issued after the
      incorporation, can only be made with the approval of the Company.

      be exercised, shall be notified in writing by the Company to all
      shareholders. A pre-emption right can be exercised during at least four
      weeks after the day the notice was received by all shareholders.

      If a shareholder has not complied with his obligation to pay the shares in
      time, he cannot execute the rights to meet and to vote in respect of his
      shares as long as he is default, and his right to dividends is deferred.

5.    In order to subscribe or acquire shares in its capital or certificates of
      beneficial ownership thereof, the Company may only grant loans not

                                   Article 6.

1.    The Board of Managing Directors shall keep a register into which the names
      and addresses of all the holders of shares are entered together with the
      nominal amount paid on every share, and the quantity and the numbers of
      the shares, held by every shareholder.

2.    The register shall likewise contain the names and addresses of those who
      have a right of usufruct or a pledge with regard to such shares, stating
      to which rights attached to the shares they are entitled pursuant to
      paragraphs 7 and 6 of this article.

3.    Every shareholder, usufructuary and pledgee, shall have the obligation to
      take care that his address is known to the Company.

4.    The register should be kept up regularly. 

      Any entry in the register and any extract, as referred to in paragraph 5,
      shall be signed by the managing director.

      usufructuary or pledgee with a

      free extract from the register concerning his rights with respect to the
      shares. 

In case a right of usufruct or a pledge is established on a share, the register
shall indicate who shall be entitled to the rights referred to in paragraphs 7
and 8 of this article.

6.    The Board of Managing Directors shall deposit the register at the office
      of the Company for inspection by shareholders as well as by usufructuaries
      and pledgees.

7.    The shares may be encumbered with usufruct and a pledge. The voting right
      in respect of the shares shall, however, remain vested in the shareholder.

8.    The usufructuary and the pledgee shall not have the rights conferred by
      law to the holders of depositary receipts of shares issued with the
      co-operation of the Company.

9.    Rights ensuing from a share and aiming at the acquisition of shares, shall
      belong to the shareholder, provided that he shall compensate the
      usufructuary for the value thereof as far as the latter is entitled to
      such compensation pursuant to his right of usufruct.

                                   Article 7.

If a share is held jointly by more than one person, the Company may require that

               Transfer and transition of shares (Blocking rules).
                                   Article 8.

1.    Every transfer of one or more shares by a shareholder may only be
      effectuated in the way and with due observance of the provisions of this
      article and article 9. These provisions need not to be observed, if within
      a period of thirty days after the shareholder who wants to transfer, has
      requested for the permission, all shareholders have granted written
      permission for the transfer and, moreover, the transfer is effected within
      three months after the approval has been granted by all shareholders.

2.    A shareholder intending to alienate one or more of his shares shall give
      notice thereof to the Board of Managing Directors and to the Board of
      Supervisory Directors, which notice shall be considered to be an offer for
      sale.

3.    As soon as possible but no later than five working days after receipt of
      that notice, the Board of Managing Directors shall give relevant notice to
      all shareholders.

4.    Within one month after the date of the notice to the shareholders, the
      shareholders shall inform the Board of Managing Directors, if they wish to
      take over either all the shares offered or part thereof.

5.    If shareholders apply for a number of shares exceeding the number that is
      available, shares shall be allocated by the Board of Managing Directors as
      far as possible in proportion to the total nominal amount of shares held
      by each applicant and, insofar proportional
<PAGE>   22

                                                                               4


      distribution is impossible, to several applicants jointly.

6.    As soon as it becomes clear that not all the shares offered are taken over
      by other shareholders, the offeror shall have the rights as hereinafter
      referred to in paragraph 13.

      Without the offeror being bound thereto in whatever way, within thirty
      days after receipt of the notice referred to in paragraph 2 the Board of
      Managing Directors may apply for the shares that are not taken over, on
      behalf of the Company.

      If the offeror wishes to accept, he may do so on the condition that the
      price to be paid be increased by the additional income tax due he has to
      pay as compared with the income tax to be paid in case of a sale to a
      third party.

7.    Within thirty days after receipt of the notice referred to in paragraph 2,
      the Board of Managing Directors shall inform the offeror whether or not
      application was made for the shares and in the affirmative, inform him of
      the name(s) of the applicant(s) and the number of shares he/they wish(es)
      to buy, while at the same time the Board of Managing Directors shall
      inform the applicant(s) of the number of shares, allocated to him/them for
      the time being, pursuant to paragraph 5.

8.    The price at which shares are to be transferred shall be fixed by the
      offeror and the applicant(s) by common agreement.

      If they fail to reach an agreement on the price within one month after the
      date of the informing notice referred to in the preceding paragraph, the
      price shall be the value of the offered shares as determined by an
      independent expert, to be appointed by the Chairman of the Chamber of
      Commerce and Industry of the district in which the Company has its
      principal office, upon request of the most diligent party. The expert so
      appointed shall take into account any bona fide offer made by a third
      party to purchase the shares, including the price and any other conditions
      of such offer.

9.    The costs of valuation shall be paid by the Company, except in case the
      price determined by the expert is equal to or more than the price
      originally offered by the offeror, in which case the costs shall be borne
      by the party requesting the independent valuation. 

      If the right referred to in paragraph 12 of the present article is made
      use of, half of the valuation costs shall be paid by the person who
      withdraws.

      The Company is obliged to provide the expert(s) with all the data relevant
      for the valuation, upon first request and without any delay, including the
      price and the conditions of the offer of a bona fide third party.

10.   The expert shall inform the Board of Managing Directors of his decision.
      Within five working days after receipt of that decision, the Board of
      Managing Directors shall notify the same to the offeror and to the
      applicant(s).

11.   After the price of all the shares has been determined,
<PAGE>   23

                                                                               5


      the offeror may demand that each of the applicants, provides security - by
      means of an irrevocable bank guarantee or otherwise - for the payment of
      the purchase price within a reasonable period of time.

12.   The offeror shall always be entitled to withdraw his offer, provided he
      does so within one month after having been informed of the applicant(s) to
      whom he may transfer all the shares offered and at which price. Shares
      should be transferred within one month after the expiration of the term
      within which the offeror may withdraw, against payment of the purchase
      price.

13.   If not all the shares offered are taken over or the above mentioned
      security, demanded by the offeror for the payment to him of the purchase
      price of all his shares, has not been granted, the offeror shall be
      entitled to withdraw in respect of all the shares offered, he may consider
      the purchase agreements and any transfer with respect to part of the
      shares as cancelled and he shall be free to transfer all the shares
      offered to whatever party he wishes, within three months after having been
      informed of the fact that there are no or not sufficient applicants or
      after it appeared that the security referred to above was not granted
      within the term fixed, provided that the transfer price is not lower than
      the price for which the shares were originally offered; in the event that
      the transfer price is lower, the shares shall be offered to the other
      shareholders first, in accordance with the rules as mentioned in this
      article and in article 9.

14.   In case the offeror fails to co-operate with the transfer, notwithstanding
      payment or security for payment of the purchase price, the Company shall
      be irrevocably authorized to effectuate the transfer and to record the
      transfer in the register of shareholders.

15.   All notices and communications referred to in this article shall be made
      by registered mail with postal receipt or by means of service of a writ.

16.   The Board of Managing Directors is obliged to keep the Board of
      Supervisory Directors informed of the progress and the results of the
      actions meant in the present article.

                                   Article 9.

1.    The shares of a shareholder, being a legal entity, which is dissolved,
      adjudicated bankrupt or has obtained a provisional official moratorium,
      and the shares being part of any community which is dissolved, shall be
      offered for sale by the person or persons entitled to transfer, within two
      months after the decease or dissolution referred to above or after any of
      the other events referred to above is irrevocably established,
      respectively after expiry of the term of two years referred to in
      paragraph 4 without the allotment mentioned therein being effectuated.

      As long as the  transfer  has not been  effectuated,  all the  rights in
      respect of the shares involved may not be

                                                                               6


      exercised.

2.    The relevant provisions of article 8 - including paragraph 1 of that
      article - shall be applicable to the offer referred to above and the
      subsequent effectuation thereof, on the understanding however, that the
      offeror shall not be entitled to withdraw as mentioned in paragraph 12 of
      article 8 and in case no offer is made the Company shall also be
      irrevocably authorized to make an offer and to effectuate the transfer. 

      If not all the shares thus offered are taken over, the shareholder shall
      be bound, however, to keep his shares and he shall be deprived of the
      right, provided for in paragraph 13 of article 8, to alienate the shares
      to whomever he wishes.

3.    The obligation to make an offer shall not apply in case of allotment to
      the person who contributed the share or the shares to the community which
      has been dissolved.

4.    The allotment referred to in the preceding paragraph shall be effectuated
      within two years after the dissolution and the Company shall be informed
      of the allotment within one month.

5.    If, owing to the same legal fact, several persons are bound to offer, they
      shall be entitled to offer the shares concerned as one package.

                               Transfer of shares.
                                   Article 10.

1.    The transfer of shares shall be effected in accordance with the applicable
      statutory regulations.

2.    In case of allotment of shares as a result of a division of a community
      and in case of establishment and transfer of a right of usufruct or pledge
      on shares, paragraph 1 shall apply accordingly.

3.    The provisions of this article can be only applied with regard to a
      transfer and allotment of shares and division of any community, if the
      provisions of article 8 and 9 have been observed. 

              Acquisition and possession of shares by the Company.
                                   Article 11.

1.    Unless the Company acquires shares for no value or under an universal
      title, the Company may, subject to prior authorization of the Board of
      Supervisory Directors and pursuant to a resolution of the general meeting,
      only acquire fully paid-up shares in its own capital, if.

      a.    the shareholders' equity of the Company, decreased with the
            acquisition price, is not less than the paid-up and claimed part of
            the capital, increased with the reserves to be kept in accordance

      b.    the nominal amount of the shares to be acquired and those already
            held by the Company and its subsidiaries jointly, amounts to no more
            than half of the issued share capital;

      c.    in the event that the current financial year has ended more than six
            months ago - the annual

                                                                               7


            accounts of the preceding year have been adopted. In this paragraph
            shares also include depositary receipts of shares. 

            A subsidiary of the Company may not subscribe or cause the
            subscription for shares in the Company's capital for its own
            account. A subsidiary of the Company may only acquire such shares
            for its own account and on a particular basis of title insofar as
            the Company itself may acquire shares in its own capital pursuant to
            the provisions of this paragraph.

2.    The Company cannot exercise voting rights in respect of shares, held by
      the Company itself, or of which it has a right of usufruct or a pledge.

      Such shares shall not be taken into consideration when calculating the
      distribution of profits or liquidation balance, unless a right of usufruct
      or a pledge has been established on those shares in favour of another
      person than the Company. 

      The provision of the first sentence of this paragraph is accordingly
      applicable to shares held by subsidiaries of the Company or on which
      subsidiaries have a right of usufruct or a pledge.

3.    Cancellation of shares held by the Company in its capital and cancellation
      after refunding of shares drawn by lot after drawing, is possible;
      resolutions with respect to cancellation shall be adopted in a general
      meeting of shareholders, convened with notification of the purpose of the
      cancellation and its procedure. A cancellation is not allowed to result in
      a paid and claimed part of the capital being lower than one/fifth part of
      the authorized capital or than the minimal capital prescribed by law at
      the moment of the resolution.

4.    Shares held by the Company itself can only be alienated in the manner
      prescribed for issue of snares not yet issued.

      The articles 8 and 9 do not apply to this alienation.

      managing  director and the  remuneration of the managing  director.  The
      remuneration and/or compensation of Supervisory  Directors shall also be
      determined by the general meeting.

      A legal entity can be a managing  director  but cannot be a  Supervisory
      Director.

1.    Every share shall represent the right to cast one vote. Blank and invalid
      votes shall be deemed not to be cast. When determining to what extent
      shareholders vote, are present or represented, or to what extent the share

      second meeting of shareholders will be called on a date which is at least
      five business days and no more than four weeks after the date of the first
      meeting of shareholders; in such second meeting resolutions on the
      subjects put before the first meeting of shareholders can be adopted in
      conformity with the two/third majority stipulated in this article
      irrespective of the number of shareholders attending such second meeting.

4.    In case votes are equally divided with regard to a proposal, on which a
      resolution may be adopted by a two/third majority of votes, the following
      rules shall apply:

      a.    Within two weeks after the meeting referred to under (b) was held,
            the Board of Managing Directors of the Company shall be bound -
            unless the proposal hereinafter stated under (b) is adopted - to
            request the President of the Chamber of Commerce and Industry,
            within the jurisdiction of which the Company is situated, to appoint
            a committee of three experts which shall decide whether the proposal
            on which votes were equally divided, shall be adopted or rejected.

      b.    As soon as there is an equal division of votes during a general
            meeting, the chairman of the meeting shall be obliged to bring up
            for discussion a new proposal aiming at not submitting

            the proposal, in respect of which during the discussions the votes
            were equally divided, to the committee of experts referred to under
            (a). 

            In case such new proposal is adopted, the proposal on which the
            votes were equally divided, shall be rejected and, therefore, shall
            not be submitted to the committee of experts referred to above for
            decision;

            in case votes are equally divided on the new proposal, made by the
            chairman, that proposal shall be deemed to be rejected and the Board
            of Managing Directors of the Company shall therefore have the
            obligation referred to under (a).

      c.    When taking its decision the committee shall first of all take into
            account the interests of the Company.

      d.    Its fees shall be paid entirely by the Company.

      e.    After being appointed the committee shall render its decision as
            soon as possible and shall inform every shareholder and the Company
            of its decision in writing.

            The committee shall not take a decision before having heard all
            parties involved in the relevant proposal or at least before having
            summoned them properly. 

            The members of the committee of experts shall render their decision
            as good men in equity. They shall establish proceeding rules
            themselves and may extend the term of their mandate. They may take
            advice from third parties. The members of the committee of experts
            shall have access to the offices and to other rooms of the Company
            and they shall be entitled to inspect all books, registers and other
            documents of the Company; moreover, the Board of Managing Directors
            is obliged to provide the members of the committee with every
            information they ask.

      f.    The decision of the committee of experts shall be recorded in the
            minute book of the Company.

            A decision taken in the way described above, shall be considered as
            a resolution of the general meeting.

                                 THE SECURITIES


SECTION 2.01. Form and Dating.

                  The Series A Securities and the Trustee's certificate of
authentication thereof shall be substantially in the form of Exhibit A hereto,
which is hereby incorporated in and expressly made a part of this Indenture. The
Series B Securities and the Trustee's certificate of authentication thereof
shall be substantially in the form of Exhibit B hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The Securities may

any notation, legend or endorse-
<PAGE>   26
                                      -20-

ment on them. Each Security shall be dated the date of its issuance and shall
show the date of its authentication.

                  Securities initially offered and sold by the Initial
Purchasers shall, unless the applicable Holder requests Securities in the form
of certificated Securities in registered form ("Physical Securities"), which
shall be in substantially the form set forth in Exhibit A hereto, be issued
initially in the form of one or more permanent Global Securities in registered
form, substantially in the form set forth in Exhibit A hereto, deposited with
the Trustee, as custodian for the Depository, and shall bear the legend set
forth in Exhibit C hereto. One or more separate Global Securities shall be
issued to represent Securities held by (i) Qualified Institutional Buyers (a
"QIB Global Security") and (ii) Persons acquiring Securities in offshore
transactions in reliance on Regulation S (a "Regulation S Global Security"). The
Company shall cause the QIB Global Securities and Regulation S Global Securities
to have separate CUSIP numbers.

                  Upon consummation of the Registration, Series B Securities may
be issued in the form of one or more permanent Global Securities in registered
form, substantially in the form set forth in Exhibit B hereto, deposited with
the Trustee, as custodian for the Depository, and shall bear the legend set
forth on Exhibit C hereto.

                  The aggregate principal amount of any Global Security may from
time to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for the Depository, as hereinafter provided.

SECTION 2.02. Execution and Authentication.

                  Two Officers, or an Officer and an Assistant Secretary, shall
sign, or one Officer shall sign and one Officer or an Assistant Secretary (each
of whom shall, in each case, have been duly authorized by all requisite
corporate actions) shall attest to, the Securities for the Company by manual or
facsimile signature.

                  If an Officer whose signature is on a Security was an Officer
at the time of such execution but no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

                  A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.

                  The Trustee shall authenticate (i) Series A Securities for
original issue in the aggregate principal amount not to exceed $265,000,000 and
(ii) Series B Securities from time to time only in exchange for a like principal
amount of Series A Securities in accordance with the Registration Rights
Agreement, in each case upon a written order of the Company in the form of an
Officers' Certificate. The Officers' Certificate shall specify the amount of
Securities to be authenticated, the series of Securities and the date on which
the Securities are to be authenticated. The aggregate principal amount of
Securities outstanding at any time may not exceed $265,000,000, except as
provided in Section 2.07. Upon receipt of a written order of the Company in the
form of an Officers' Certificate, the Trustee shall authenticate Securities in
substitution for Securities originally issued to reflect any name change of the
Company.

                  The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate Securities. Unless otherwise provided
in the appointment, an authenticating agent may authenti-
<PAGE>   27
                                      -21-

cate Securities whenever the Trustee may do so. Each reference in this Indenture
to authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company
and Affiliates of the Company.

                  The Securities shall be issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.

SECTION 2.03. Registrar and Paying Agent.

                  The Company shall maintain an office or agency in the Borough
of Manhattan, The City of New York, and, so long as the Securities are listed on
the Luxembourg Stock Exchange and the rules of such stock exchange require, in
Luxembourg where (a) Securities may be presented or surrendered for registration
of transfer or for exchange ("Registrar"), (b) Securities may be presented or
surrendered for payment ("Paying Agent") and (c) notices and demands in respect
of the Securities and this Indenture may be served. The Registrar shall keep a
register or registers of the Securities and of their transfer and exchange. The
Company, upon notice to the Trustee, may appoint one or more co-Registrars and
one or more additional Paying Agents. The term "Paying Agent" includes any
additional Paying Agent. Except as provided herein, the Company, or any
Subsidiary may act as Paying Agent, Registrar or co-Registrar.

                  The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture, which shall incorporate the
provisions of the TIA. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall notify the Trustee of the
name and address of any such Agent. If the Company fails to maintain a Registrar
or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as
such and shall be entitled to appropriate compensation in accordance with
Section 7.07.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent until such time as the Trustee has resigned or a successor has been
appointed.

SECTION 2.04. Paying Agent to Hold Assets in Trust.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all assets held by the Paying Agent for the
payment of principal of, or interest on, the Securities, and shall notify the
Trustee of any Default by the Company in making any such payment. The Company at
any time may require a Paying Agent to distribute all assets held by it to the
Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent (if other than the Company), the Paying Agent shall have no further
liability for such assets. If the Company, any Subsidiary or any of their
respective Affiliates acts as Paying Agent, it shall, on or before each due date
of the principal of or interest on the Securities, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure so to act.

SECTION 2.05. Securityholder Lists.

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

SECTION 2.06. Transfer and Exchange.

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

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

SECTION 2.07. Replacement Securities.

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

                  Every replacement Security is an additional obligation of the
Company.

                                      -23-

SECTION 2.08. Outstanding Securities.

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

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

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

SECTION 2.09. Treasury Securities.

                  In determining whether the Holders of the required principal
amount of Securities have concurred in any direction, waiver or consent,
Securities owned by the Company or any of its Affiliates shall be disregarded,
except that, for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities
that a Trust Officer of the Trustee actually knows are so owned shall be
disregarded.

SECTION 2.10. Temporary Securities.

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

SECTION 2.11. Cancellation.

                  The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar and the Paying Agent shall forward to the
Trustee any Securities surrendered to them for transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel all Securities surrendered for transfer,
exchange, payment or cancellation and deliver to the Company such cancelled
Securities for disposal. Subject to Section 2.07, the Company may not issue new
Securities to replace Securities that it has paid or delivered to the Trustee
for cancellation. If the Company shall acquire any of the Securities, such
acquisition shall not operate as a redemption or satisfaction of the
Indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 2.11. The
Trustee shall cancel all Securities surrendered for transfer, exchange, payment
or cancellation and shall dispose of them in accordance with its normal
procedure.

SECTION 2.12. Defaulted Interest.

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

SECTION 2.13. CUSIP Number.

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

SECTION 2.14. Deposit of Moneys.

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

SECTION 2.15. Book-Entry Provisions for Global Securities.

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

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

                  (b) Transfers of Global Securities shall be limited to

respective nominees. Interests of beneficial owners in the Global Securities may
be transferred or exchanged for Physical Securities in accordance with the rules
and procedures of the Depository and the provisions of Section 2.16. In
addition, Physical Securities shall be transferred to all beneficial owners in
exchange for their beneficial interests in Global Securities if (i) the
Depository notifies the Company that it is unwilling or unable to continue as
Depository for any Global Security and a successor Depository is not appointed
by the Company within 90 days of such notice or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a request from the
Depository to issue Physical Securities.

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

                  (d) Any Physical Security constituting a Restricted Security
delivered in exchange for an interest in a Global Security pursuant to paragraph
(b) of this Section 2.15 shall, except as otherwise provided by Section 2.16,
bear the Private Placement Legend.

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

Securities presented or surrendered for registration of transfer or exchange:

                  (B)      written instructions directing the Registrar or
                           co-Registrar to make, or to direct the Depository to
                           make, an endorsement on the applicable Global
                           Security to reflect an increase in the aggregate
                           amount of the Securities represented by the Global

Global Security to be increased accordingly. If no Global Security representing
Securities held by Qualified Institutional Buyers, Institutional Accredited
Investors or Persons acquiring Securities in offshore transactions in reliance

Depository or its nominee, requesting the registration of transfer of an
interest in a QIB Global Security, an Accredited Investor Global Security or
Regulation S Global Security, as the case may be, to another type of Global

type of Global Security required to represent the interest as requested to be
transferred is not then outstanding, only the Global Security representing the
interest being transferred), the Registrar or Co-Registrar shall cancel such
Global Securities (or Global Security) and the Company shall issue and the
Trustee shall, upon written instructions from the Company in accordance with
Section 2.02, authenticate new Global Securities of the types so cancelled (or

requested to be transferred) reflecting the applicable increase and decrease of
the principal amount of Securities represented by such types of Global
Securities, giving effect to such transfer. If the applicable type of Global
Security required to represent the interest as requested to be transferred is
not outstanding at the time of such request, the Company shall issue and the
Trustee shall, upon written instructions from the Company in accordance with
Section 2.02, authenticate a new Global Security of such type in principal
amount equal to the principal amount of the interest requested to be
transferred.

                  (d)  Transfer of a Beneficial Interest in a Global Security
for a Physical Security.

                 (i) Any Person having a beneficial interest in a Global
         Security may upon request exchange such beneficial interest for a

         and upon receipt by the Trustee of a written order or such other form

                           the Person designated by the Depository as being the
                           beneficial owner, a certification from such Person to
                           that effect (substantially in the form of Exhibit D
                           hereto); or

                  (B)      if such beneficial interest is being transferred to a
                           Qualified Institutional Buyer in accordance with Rule
                           l44A, a certification to that effect (substantially
                           in the form of Exhibit D hereto); or

                           Company to the effect that such transfer is in
                           compliance with the Securities Act; or

                           satisfactory to the Company to the effect that such
                           transfer is in compliance with the Securities Act; or

                  (E)      if such beneficial interest is being transferred in
                           reliance on Rule 144 under the Securities Act,
                           delivery of a certification to that effect
                           (substantially in the form of Exhibit D hereto) and
                           an Opinion of Counsel reasonably satisfactory to the
                           Company to the effect that such transfer is in
                           compliance with the Securities Act; or

                  (F)      if such beneficial interest is being transferred in
                           reliance on another exemption from the registration
                           requirements of the Securities Act, a certification
                           to that effect (substantially in the form of Exhibit
                           D hereto) and an Opinion of Counsel reasonably

                           transfer is in compliance with the Securities Act,

         then the Registrar or co-Registrar will cause, in accordance with the
         standing instructions and procedures existing between the Depository
         and the Registrar or co-Registrar, the aggregate principal amount of
         the applicable Global Security to be reduced and, following such
         reduction, the Company will execute and, upon receipt of an
         authentication order in the form of an Officers' Certificate in

         a Global Security pursuant to this Section 2.16(d) shall be registered
         in such names and in such authorized denominations as the Depository,
         pursuant to instructions from its direct or indirect participants or
         otherwise, shall instruct the Registrar or co-Registrar in writing. The

successor Depository or a nominee of such successor Depository.

                  (f) Private Placement Legend. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the
Registrar or co-Registrar shall deliver Securities that do not bear the Private
Placement Legend. Upon the transfer, exchange or replacement of Securities
bearing the Private Placement Legend, the Registrar or co-Registrar shall
deliver only Securities that bear the Private Placement Legend unless, and the
Trustee is hereby authorized to deliver Securities without the Private Placement
Legend if, (i) there is delivered to the Trustee an Opinion of Counsel
reasonably satisfactory to the Company and the Trustee to the effect that
neither such legend nor the related restrictions on transfer are required in
order to maintain compliance with the provisions of the Securities Act or (ii)
such Security has been sold pursuant to an effective registration statement
under the Securities Act (including pursuant to a Registration).

                  (g) General. By its acceptance of any Security bearing the
Private Placement Legend, each Holder of such a Security acknowledges the
restrictions on transfer of such Security set forth in this Indenture and in the
Private Placement Legend and agrees that it will transfer such Security only as
provided in this Indenture.

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

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

                                  ARTICLE THREE

                                   REDEMPTION


SECTION 3.01.  Notices to Trustee.

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

SECTION 3.02.  Selection of Securities to Be Redeemed.

                  If less than all of the Securities are to be redeemed pursuant
to paragraph 5(a) or (b) of the Securities, the Trustee shall select the
Securities to be redeemed in compliance with the requirements of the national
securities exchange, if any, on which the Securities are listed or, if the
Securities are not then listed on a national securities exchange, on a pro rata
basis, by lot or in such other manner as the Trustee shall deem fair and
appropriate. The Trustee shall make the selection from the Securities then
outstanding, subject to redemption and not previously called for redemption.

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

SECTION 3.03.  Notice of Redemption.

                  At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail a notice of redemption by first-class mail to each
Holder whose Securities are to be redeemed at such Holder's registered address;
provided, however, that notice of a redemption pursuant to paragraph 5(b) of the
<PAGE>   36
                                      -30-


Securities shall be mailed to each Holder whose Securities are to be redeemed no
later than 60 days following the consummation of the last Public Equity Offering
or Strategic Equity Investment resulting in gross cash proceeds to the Company,
when aggregated with all prior Public Equity Offerings and Strategic Equity
Investments, of at least $75.0 million.

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

                  (1)      the Redemption Date;

                  (2)      the redemption price;

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

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

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

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

portions thereof called for redemption on that date which have been delivered by
the Company to the Trustee for cancellation.

provided in the Securities shall not be so paid on the Redemption Date due to
the failure of the Company to deposit with the Paying Agent money

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

statutory) and material franchises of the Company and the Restricted
Subsidiaries; provided, however, that the Company shall not be required to
preserve any such right or franchise, or the corporate existence of any
Restricted Subsidiary, if the Board of Directors of the Company shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and the Restricted Subsidiaries, taken as a whole, and
that the loss thereof is not, and will not be, adverse in any material respect
to the Holders; provided, further, however, that a determination of the Board of
Directors of the

Subsidiary; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith

or both, would constitute such a default) under such Indebtedness, the Company

status of such default or event and what action the Company is taking or
proposes to take with respect thereto.

Restricted Subsidiary from discontinuing the use, operation or maintenance of
any of such properties, or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors or of the board of
directors of the Restricted Subsidiary concerned, or of an officer (or other
agent employed by the Company or of any Restricted Subsidiary) of the Company or
such Restricted Subsidiary having managerial responsibility for any such
property, desirable in the conduct of the business of the Company or any
Restricted Subsidiary, and if such discontinuance or disposal is not adverse in
any material respect to the Holders.

certificate to be delivered by the Company pursuant to this Section 4.07 shall
be for the fiscal year ending December 31, 1997.

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

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

SECTION 4.09.  Provision of Financial Information.

                  Whether or not the Company is subject to Section 13(a) or
15(d) of the Exchange Act, or any successor provision thereto, the Company shall
file with the SEC (if permitted by SEC practice and applicable law and
regulations) the annual reports, quarterly reports and other documents which the
Company would have been required to file with the SEC pursuant to such Section
13(a) or 15(d) or any successor provision thereto if the Company were so
required, such documents to be filed with the SEC on or prior to the respective
dates (the "Required Filing Dates") by which the Company would have been
required so to file such documents if the Company were so required; provided,
however, that until the Company is subject to Section 13(a) or Section 15(d) of
the Exchange Act or any successor provisions thereto, the Required Filing Dates
for such quarterly reports shall be 75 days following the end of the applicable
fiscal quarter. The Company shall also in any event (a) within 15 days of each

to be transmitted) by mail to all Holders, as their names and addresses appear
in the Note register, without cost to such Holders, and (ii) file with the
Trustee, copies of the annual reports, quarterly reports and other documents

sentence, or, if such filing is not so permitted, information and data of a
similar nature, and (b) if, notwithstanding the preceding sentence, filing such
documents by the Company with the SEC is not permitted by SEC practice or
applicable law or regulations, promptly upon written request supply copies of
such documents to any Holder. In addition, for so long as any Securities remain

upon the request of any such holder.

SECTION 4.10.  Change of Control.

                  (a) Following the occurrence of a Change of Control (the date

prescribed by this Indenture and shall, within 30 days after the Change of
Control Date, make an Offer to Purchase all Securities then outstanding at a
purchase price in cash equal to 101% of the 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 Luxembourg
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 this Indenture applicable to an Offer to Purchase made by
the Company and purchases all Securities validly tendered and not withdrawn
under such Offer to Purchase. Each Holder shall be entitled to tender all or any
portion of the Securities owned by such Holder pursuant to the Offer to
Purchase, subject to the requirement that any portion of a Security tendered
must be tendered in an integral multiple of $1,000 principal amount.

Purchase, the Company shall (i) accept for payment all Securities or portions
thereof validly tendered pursuant to the Offer, (ii) deposit with the Paying

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

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

                  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

                  Designation Amount with respect to such Restricted Subsidiary
                  upon its Designation), minus

                          (6) with respect to each Subsidiary of the Company

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)

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, that in the

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

         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 Securities;
         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;

                                      -38-


               (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 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

         (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 Section 4.18.

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

SECTION 4.13.  Limitations 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 Section 4.16; (c) any encumbrance or re-
<PAGE>   45
                                      -39-


striction 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 Section 4.15) that restrict the transfer
of property subject to such agreements; (g) any agreement or other instrument of
a Person acquired by the Company or any Restricted 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.

SECTION 4.14.  Designation of Unrestricted Subsidiaries.

                  (a) The Company may designate any Subsidiary of the Company as
an "Unrestricted Subsidiary" under this 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 Section 4.12(a); 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 Section 4.11 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;
<PAGE>   46
                                      -40-



                (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 Section
         4.17 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.

SECTION 4.15.  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 Securities,
effective provision is made to secure the Securities equally and ratably with or
prior to such obligation with a Lien on the same collateral and (ii) in the case
of any Lien securing an obligation that is subordinated in right of payment to
the Securities, effective provision is made to secure the Securities with a Lien
on the same collateral that is prior to the Lien securing such subordinated
obligation, in each case, for so long as such obligation is secured by such
Lien.

SECTION 4.16.  Limitation on Asset Sales.

                  The Company shall not, and shall not cause or permit any
Restricted 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 (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
<PAGE>   47
                                      -41-


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 Securities 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 Securities validly tendered and not withdrawn pursuant to an
Offer to Purchase is less than the Excess Proceeds, the Company may use such
surplus for general corporate purposes. If the aggregate amount of principal and
accrued interest of Securities validly tendered and not withdrawn by Holders
thereof exceeds the amount of Securities that can be purchased with the Note
Portion of Excess Proceeds, Securities to be purchased will be selected pro rata
based on the aggregate principal amount of Securities tendered by each Holder.
Upon completion of an Offer to Purchase, the amount of Excess Proceeds 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 Securities (the "Other Debt") requires an offer to
purchase to be made to repurchase such Other Debt upon the consummation of an
Asset Sale, the Company may apply the Excess Proceeds otherwise required to be
applied to an Offer to Purchase to offer to purchase such Other Debt and to an
Offer to Purchase so long as the amount of such Excess Proceeds applied to
purchase the Securities is not less than the 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 Securities 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
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and Rule
14e-1 under, the Exchange Act, and any violation of the provisions of 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.

SECTION 4.17.  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
<PAGE>   48
                                      -42-


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 transactions 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 Section
4.11.

SECTION 4.18.  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 Securities 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 Securities, then the guarantee of such Guaranteed
Indebtedness shall be pari passu with, or subordinated to, the Subsidiary
Guarantee or (B) subordinated to the Securities, 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
Securities.

                  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 this Indenture) or (ii) the release or discharge of the guarantee which
resulted in the creation of such Subsidiary Guarantee, except a discharge or
release by or as a result of payment under such guarantee.

SECTION 4.19. Limitation on the Issuance and Sale of 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
issuance or sale, such Restricted Subsidiary would no longer constitute a
Restricted Subsidiary; or (iii) in the case of issuance of Equity Interests by a
non-Wholly Owned Restricted Subsidiary if, after giving effect to such issuance,
the Company maintains its direct or indirect percentage of beneficial and
economic ownership of such non-Wholly Owned Restricted Subsidiary.

SECTION 4.20.  Additional Amounts.

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

SECTION 4.21.  Deposit of Funds with Escrow Agent.

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

                                      -44-


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

sell, convey, assign, transfer, lease or otherwise dispose of all or
substantially all of the property and assets of the Company and the Restricted
Subsidiaries, taken as a whole, to any Person or Persons (other than any
Restricted Subsidiary), in each case, in a single transaction or series of

corporation organized and validly existing under the laws of The Netherlands,
the United States of America or any State thereof or the District of Columbia,
and shall, in any such case, expressly assume by a supplemental indenture, the

assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all the properties and assets of one or
more Restricted Subsidiaries the Equity Interests of which constitutes all or
substantially all the properties and assets of the Company shall be deemed to be
the transfer of all or substantially all the properties and assets of the
Company.

SECTION 5.02.  Successor Corporation Substituted.

                  In the event of any transaction (other than a lease) described

covenant in which the Company is not the Surviving Person and the Surviving
Person is to assume all the Obligations of the Company under the Securities,
this Indenture, the Escrow Agreement and the Registration Rights Agreement
pursuant to a supplemental indenture, such Surviving Person shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
and the Company shall be discharged from its Obligations under the Securities,
this Indenture, the Escrow Agreement and the Registration Rights Agreement.

                              DEFAULT AND REMEDIES


SECTION 6.01.  Events of Default.

                  Each of the following shall be an "Event of Default" for
purposes of this Indenture:

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

                  (2) failure to pay any interest on any Security when due,
         continued for 30 days or more;

                  (3) failure to pay on the Purchase Date the Purchase Price for

         Section 5.01;

                  (5) failure to perform any other covenant, warranty or
         agreement of the Company under this Indenture or the Escrow Agreement
         or in the Securities, and the Default continues for the period and
         after the notice specified in the last paragraph of this Section 6.01;

                  (6) 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 aggregate for
         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;

                  (7) there shall have been any final judgment or judgments
         against the Company or any Restricted Subsidiary in an amount of $10.0
         million or more which remain undischarged or unstayed for a period of
         60 consecutive days;

                  (8) the Company or any Significant Restricted Subsidiary
         pursuant to or within the meaning of any Bankruptcy Law:

                           (A) admits in writing its inability to pay its debts
                  generally as they become due,

                           (B) commences a voluntary case or proceeding,

                           (C) consents to the entry of an order for relief
                  against it in an involuntary case or proceeding,
<PAGE>   52
                                      -46-


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

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

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

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

                           (A) is for relief against the Company or any
                  Significant Restricted Subsidiary in an involuntary case or
                  proceeding,

                           (B) appoints a Custodian of the Company or any
                  Significant Restricted Subsidiary or for all or substantially
                  all of its property, or

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

                  (10) the Company challenges the Lien on the Collateral under
         the Escrow Agreement prior to such time as the Collateral is to be
         released to the Company, or the Collateral becomes subject to any Lien
         other than the Lien under the Escrow Agreement.

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

                  A Default under clause (5) is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in aggregate
principal amount of the outstanding Securities notify the Company and the
Trustee, of the Default in writing and the Company does not cure the Default
within 30 days after receipt of the notice. The notice must specify the Default,
demand that it be remedied and state that the notice is a "Notice of Default."
Such notice shall be given by the Trustee if so requested by the Holders of at
least 25% in principal amount of the Securities then outstanding. When a Default
is cured, it ceases.

SECTION 6.02.  Acceleration.

                  If an Event of Default with respect to the Securities (other
than an Event of Default specified in clause (8) or (9) of Section 6.01 with
respect to the Company) occurs and is continuing, the Trustee or the Holders of
at least 25% in aggregate principal amount of the outstanding Securities by
notice in writing to the Company may declare the unpaid principal of and accrued
interest to the date of acceleration on all outstanding Securities to be due and
payable immediately and, upon any such declaration, such principal amount and
accrued interest, notwithstanding anything contained in this Indenture or the
Securities to the contrary, shall become immediately due and payable.
<PAGE>   53
                                      -47-


                  If an Event of Default specified in clause (8) or (9) of
Section 6.01 with respect to the Company occurs, all unpaid principal of and
accrued interest on all outstanding Securities shall ipso facto become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder.

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

SECTION 6.03.  Other Remedies.

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

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

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

SECTION 6.04.  Waiver of Past Default.

                  Subject to Sections 2.09, 6.07 and 9.02, prior to the
declaration of acceleration of the Securities, the Holders of not less than a
majority in aggregate principal amount of the outstanding Securities by written
notice to the Trustee may waive an existing Default and its consequences, except
a Default in the payment of principal of or interest on any Security as
specified in Section 6.01(1) or (2) or a Default in respect of any term or
provision of this Indenture that may not be amended or modified without the
consent of each Holder affected as provided in Section 9.02. The Company shall
deliver to the Trustee an Officers' Certificate stating that the requisite
percentage of Holders have consented to such waiver and attaching copies of such
consents. In case of any such waiver, the Company, the Trustee and the Holders
shall be restored to their former positions and rights hereunder and under the
Securities, respectively. This paragraph of this Section 6.04 shall be in lieu
of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is
hereby expressly excluded from this Indenture and the Securities, as permitted
by the TIA.

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

SECTION 6.05.  Control by Majority.

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

SECTION 6.06.  Limitation on Suits.

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

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

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

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

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

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

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

SECTION 6.07.  Rights of Holders to Receive Payment.

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

SECTION 6.08.  Collection Suit by Trustee.

                  If an Event of Default in payment of principal or interest
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust
<PAGE>   55
                                      -49-


against the Company or any other obligor on the Securities for the whole amount
of principal and accrued interest remaining unpaid, together with interest
overdue on principal and to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per annum
borne by the Securities and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.  Trustee May File Proofs of Claim.

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

SECTION 6.10.  Priorities.

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

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

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

                  Third: to the Company.

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

SECTION 6.11.  Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 6.11 shall not apply to a suit by the Trustee,
a suit by a Holder or group of Holders of more than 10% in aggregate principal
amount of the outstanding Securities, or to any suit instituted by any Holder
for the
<PAGE>   56
                                      -50-


enforcement or the payment of the principal or interest on any Securities on or
after the respective due dates therefor.

                                     TRUSTEE


SECTION 7.01.  Duties of Trustee.

                  (a) If a Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

                  (b) Except during the continuance of a Default:

                  (1) The Trustee shall not be liable except for the performance
         of such duties as are specifically set forth herein; and

                  (2) In the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions conforming to the requirements of this Indenture or the Escrow
         Agreement; however, in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall examine such certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture or the Escrow Agreement.

                  (c) The Trustee shall not be relieved from liability for its
own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (1) This paragraph does not limit the effect of paragraph (b)
         of this Section 7.01;

                  (2) The Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer, unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts; and

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 6.05.

                  (d) No provision of this Indenture or the Escrow Agreement
shall require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or to take
or omit to take any action under this Indenture or take any action at the
request or direction of Holders if it shall have reasonable grounds for
believing that repayment of such funds is not assured to it or it does not
receive from such Holders an indemnity or security satisfactory to it in its
sole discretion against such risk, liability, loss, fee or expense which might
be incurred by it in compliance with such request or direction.

                  (e) Every provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section
7.01.
<PAGE>   57

                  (f) The Trustee shall not be liable for interest on any money
received by it. Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

SECTION 7.02.  Rights of Trustee.

                  Subject to Section 7.01:

                  (a) The Trustee may rely on any document believed by it to be
genuine and to have been signed or presented by the proper person. The Trustee
need not investigate any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate and/or an Opinion of Counsel, which shall
conform to the provisions of Section 10.05. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on such
certificate or opinion.

                  (c) The Trustee may act through attorneys and agents of its
selection and shall not be responsible for the misconduct or negligence of any
agent or attorney (other than an agent who is an employee of the Trustee)
appointed with due care.

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it reasonably believes to be authorized or
within its rights or powers.

                  (e) The Trustee may consult with counsel of its selection and
the advice or opinion of such counsel as to matters of law shall be full and
complete authorization and protection from liability in respect of any action
taken, omitted or suffered by it hereunder in good faith and in accordance with
the advice or opinion of such counsel.

                  (f) Any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution.

                  (g) The Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture or the Escrow Agreement
at the request or direction of any of the Securityholders pursuant to this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction.

                  (h) The Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to
examine the books, records and premises of the Company, personally or by agent
or attorney.

                  (i) The Trustee shall not be deemed to have notice of any
Event of Default unless a Trust Officer of the Trustee has actual knowledge
thereof or unless the Trustee shall have received written notice thereof at the
Corporate Trust Office of the Trustee, and such notice references the Securities
and this Indenture.

SECTION 7.03.  Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company or
its Affiliates with the same rights it would have if it were not Trustee,
subject to Section 7.10 hereof. Any Agent may do the same with like rights.
However, the Trustee is subject to Sections 7.10 and 7.11.

SECTION 7.04.  Trustee's Disclaimer.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture, the Escrow
Agreement or the Securities, it shall not be accountable for the Company's use
of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company in this Indenture or any document issued in connection
with the sale of Securities or any statement in the Securities other than the
Trustee's certificate of authentication.

SECTION 7.05.  Notice of Defaults.

                  If a Default occurs and is continuing and the Trustee actually
knows of such Default, the Trustee shall mail to each Securityholder notice of
the Default within 30 days after the occurrence thereof. Except in the case of a
Default in payment of principal of or interest on any Security or a Default in
complying with any of the provisions of the Escrow Agreement, the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interest of
Securityholders. This Section 7.05 shall be in lieu of the proviso to Section
315(b) of the TIA and such proviso to Section 315(b) of the TIA is hereby
expressly excluded from this Indenture and the Securities, as permitted by the
TIA.

SECTION 7.06.  Reports by Trustee to Holders.

                  If required by TIA Section 313(a), within 60 days after each
September 1 beginning with September 1, 1998, the Trustee shall mail to each
Securityholder a report dated as of such September 1 that complies with TIA
Section 313(a). The Trustee also shall comply with TIA Section 313(b), (c) and
(d).

                  A copy of each such report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange, if any, on
which the Securities are listed.

                  The Company shall promptly notify the Trustee in writing if
the Securities become listed on any stock exchange or of any delisting thereof.

SECTION 7.07.  Compensation and Indemnity.

                  The Company shall pay to the Trustee from time to time such
compensation as the Company and the Trustee shall from time to time agree in
writing for its services. The Trustee's compensation shall not be limited by any
law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable disbursements, expenses
and advances (including fees, disbursements and expenses of its agents and
counsel) incurred or made by it in addition to the compensation for its services
except any such disbursements, expenses and advances as may be attributable to
the Trustee's negligence or bad faith. Such expenses shall include the
reasonable compensation, disbursements and expenses of the Trus-

                                      -53-


tee's agents, accountants, experts and counsel and any taxes or other expenses
incurred by a trust created pursuant to Section 8.01 hereof.

                  The Company shall indemnify the Trustee, its agents and
officers, for, and hold it harmless against any and all loss, damage, claims,
liability or expense, including taxes (other than franchise taxes imposed on the
Trustee and taxes based upon, measured by or determined by the income of the
Trustee), arising out of or in connection with the acceptance or administration
of the trust or trusts hereunder, including the costs and expenses of defending
itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent that
such loss, damage, claim, liability or expense is due to its own negligence or
bad faith. The Trustee shall notify the Company promptly of any claim asserted
against the Trustee for which it may seek indemnity. However, the failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense (and may employ its own counsel) at the Company's
expense; provided, however, that the Company's reimbursement obligation with
respect to counsel employed by the Trustee will be limited to the reasonable
fees and expenses of such counsel.

                  The Company need not pay for any settlement made without its
written consent, which consent shall not be unreasonably withheld. The Company
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee as a result of the violation of this Indenture by the
Trustee.

                  To secure the Company's payment obligations in this Section
7.07, the Trustee shall have a Lien prior to the Securities against all money or
property held or collected by the Trustee, in its capacity as Trustee, except
money or property held in trust to pay principal of or interest on particular
Securities or the Purchase Price or redemption price of any Securities to be
purchased or pursuant to an Offer to Purchase or redeemed.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(8) or (9) occurs, the expenses
(including the reasonable fees and expenses of its agents and counsel) and the
compensation for the services shall be preferred over the status of the Holders
in a proceeding under any Bankruptcy Law and are intended to constitute expenses
of administration under any Bankruptcy Law. The Company's obligations under this
Section 7.07 and any claim arising hereunder shall survive the resignation or
removal of any Trustee, the discharge of the Company's obligations pursuant to
Article Eight and any rejection or termination under any Bankruptcy Law, and the
termination of this Indenture.

SECTION 7.08.  Replacement of Trustee.

                  The Trustee may resign at any time by so notifying the Company
in writing. The Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Trustee and the Company in
writing and may appoint a successor Trustee with the Company's consent. The
Company may remove the Trustee if:

                  (1) the Trustee fails to comply with Section 7.10;

                  (2) the Trustee is adjudged a bankrupt or an insolvent under
         any Bankruptcy Law;

                  (3) a custodian or other public officer takes charge of the
         Trustee or its property; or

                  (4) the Trustee becomes incapable of acting.
<PAGE>   60
                                      -54-


                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in principal amount of the Securities may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. As promptly as
practicable after that, the retiring Trustee shall transfer, after payment of
all sums then owing to the Trustee pursuant to Section 7.07, all property held
by it as Trustee to the successor Trustee, subject to the Lien provided in
Section 7.07, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have the rights, powers and duties of
the Trustee under this Indenture. A successor Trustee shall mail notice of its
succession to each Securityholder.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in principal amount of the outstanding
Securities may petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 7.10, any
Securityholder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

                  Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

SECTION 7.09.  Successor Trustee by Merger, etc.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation or banking corporation, the resulting, surviving or transferee
corporation or banking corporation without any further act shall be the
successor Trustee.

SECTION 7.10.  Eligibility; Disqualification.

                  This Indenture shall always have a Trustee which shall be
eligible to act as Trustee under TIA Sections 310(a)(1) and 310(a)(2). The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition. If the Trustee
has or shall acquire any "conflicting interest" within the meaning of TIA
Section 310(b), the Trustee and the Company shall comply with the provisions of
TIA Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 7.10, the Trustee
shall resign immediately in the manner and with the effect hereinbefore
specified in this Article Seven.

SECTION 7.11.  Preferential Collection of Claims Against Company.

                  The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein.

                             DISCHARGE OF INDENTURE


SECTION 8.01.  Termination of Company's Obligations.

                  The Company may terminate its substantive obligations in
respect of the Securities by delivering all outstanding Securities to the
Trustee for cancellation and paying all sums payable by it on account of
principal of and interest on all Securities or otherwise. In addition to the
foregoing, the Company may terminate its obligation under Sections 4.04, 4.06,
4.08, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 (and
no Default with respect to such Sections under Section 6.01(5) shall thereafter
apply), by (i) depositing with the Trustee, under the terms of an irrevocable
trust agreement, money or U. S. Government Obligations sufficient (without
reinvestment) to pay all remaining indebtedness on the Securities at maturity or
an earlier redemption, (ii) delivering to the Trustee either an Opinion of
Counsel or a ruling directed to the Trustee from the Internal Revenue Service to
the effect that the Holders of the Securities will not recognize income, gain or
loss for federal income tax purposes as a result of such deposit and termination
of obligations, (iii) delivering to the Trustee an Opinion of Counsel to the
effect that the Company's exercise of its option under this paragraph will not
result in any of the Company, the Trustee or the trust created by the Company's
deposit of funds pursuant to this provision becoming or being deemed to be an
"investment company" under the Investment Company Act of 1940, as amended (the
"Investment Company Act"), and (iv) delivering to the Trustee an Officers'
Certificate and an Opinion of Counsel each stating compliance with all
conditions precedent provided for herein. In addition, the Company may, provided
that no Default has occurred and is continuing or would arise therefrom (or,
with respect to a Default specified in Section 6.01(8) or (9), occurs at any
time on or prior to the 91st calendar day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until after
such 91st day)), terminate all of its substantive obligations in respect of the
Securities (including its obligations to pay the principal of and interest on
the Securities) by (i) depositing with the Trustee, under the terms of an
irrevocable trust agreement, money or U.S. Government Obligations sufficient
(without reinvestment) to pay all remaining indebtedness on the Securities at
maturity or upon earlier redemption, (ii) delivering to the Trustee either a
ruling directed to the Trustee from the Internal Revenue Service to the effect
that the Holders of the Securities will not recognize income, gain or loss for
federal income tax purposes as a result of such deposit and termination of
obligations or an Opinion of Counsel addressed to the Trustee based upon such a
ruling or based on a change in the applicable Federal tax law since the date of
this Indenture to such effect, (iii) delivering to the Trustee an Opinion of
Counsel to the effect that the Company's exercise of its option under this
paragraph will not result in any of the Company, the Trustee or the trust
created by the Company's deposit of funds pursuant to this provision becoming or
being deemed to be an "investment company" under the Investment Company Act and
(iv) delivering to the Trustee an Officers' Certificate and an Opinion of
Counsel each stating compliance with all conditions precedent provided for
herein.

                  Notwithstanding the foregoing paragraph, the Company's
obligations under Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.10, 2.12, 2.13
and 4.01 (but not with respect to termination of substantive obligations
pursuant to the third sentence of the foregoing paragraph), 4.02, 7.07, 7.08,
8.03 and 8.04 shall survive until the Securities are no longer outstanding.
Thereafter the Company's obligations in Sections 7.07, 8.03 and 8.04 shall
survive.
<PAGE>   62
                                      -56-


                  After such delivery or irrevocable deposit and delivery of an
Officers' Certificate and Opinion of Counsel, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Securities and this Indenture except for those surviving obligations specified
above.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U. S. Government
Obligations deposited pursuant to this Section 8.01 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of outstanding Securities.

SECTION 8.02.  Application of Trust Money.

                  The Trustee shall hold in trust money or U. S. Government
Obligations deposited with it pursuant to Section 8.01, and shall apply the
deposited money and the money from United States Government Obligations in
accordance with this Indenture solely to the payment of principal of and
interest on the Securities.

SECTION 8.03.  Repayment to Company.

                  Subject to Sections 7.07 and 8.01, the Trustee shall promptly
pay to the Company upon written request any excess money held by it at any time.
The Trustee shall pay to the Company upon written request any money held by it
for the payment of principal or interest that remains unclaimed for two years;
provided, however, that the Trustee before being required to make any payment
may at the expense of the Company cause to be published once in a newspaper of
general circulation in The City of New York and in a newspaper of general
circulation in Luxembourg or mail to each Holder entitled to such money notice
that such money remains unclaimed and that, after a date specified therein which
shall be at least 30 days from the date of such publication or mailing, any
unclaimed balance of such money then remaining shall be repaid to the Company.
After payment to the Company, Securityholders entitled to money must look to the
Company for payment as general creditors unless an applicable abandoned property
law designates another person and all liability of the Trustee or Paying Agent
with respect to such money shall thereupon cease.

SECTION 8.04.  Reinstatement.

                  If the Trustee is unable to apply any money or U.S. Government
Obligations in accordance with Section 8.01 by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01 until such
time as the Trustee is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 8.01; provided, however, that if the
Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS


SECTION 9.01.  Without Consent of Holders.

                  The Company, when authorized by a resolution of its Board of
Directors, and the Trustee may amend or supplement this Indenture or the
Securities without notice to or consent of any Securityholder:

                  (i) to cure any ambiguity, defect or inconsistency; provided,
         however, that such amendment or supplement does not materially
         adversely affect the rights of any Holder;

                  (ii) to effect the assumption by a successor Person of all
         obligations of the Company under the Securities, this Indenture, the
         Registration Rights Agreement and the Escrow Agreement in connection
         with any transaction complying with Article Five of this Indenture;

                  (iii) to provide for uncertificated Securities in addition to
         or in place of certificated Securities;

                  (iv) to comply with any requirements of the SEC in order to
         effect or maintain the qualification of this Indenture under the TIA;

                  (v) to make any change that would provide any additional
         benefit or rights to the Holders;

                  (vi) to make any other change that does not materially
         adversely affect the rights of any Holder under this Indenture;

                  (vii) to add to the covenants of the Company for the benefit
         of the Holders, or to surrender any right or power herein conferred
         upon the Company; or

                  (viii) to secure the Securities pursuant to the requirements
         of Section 4.20 or otherwise;

provided, however, that the Company has delivered to the Trustee an Opinion of
Counsel stating that such amendment or supplement complies with the provisions
of this Section 9.01.

SECTION 9.02.  With Consent of Holders.

                  Subject to Section 6.07, the Company, when authorized by a
resolution of its Board of Directors, and the Trustee may amend or supplement
this Indenture or the Securities with the written consent of the Holders of a
majority in principal amount of the outstanding Securities. Subject to Section
6.07, the Holders of a majority in principal amount of the outstanding
Securities may waive compliance by the Company with any provision of this
Indenture or the Securities. However, without the consent of the Holder of each
Security affected, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.04, may not:

                  (1) change the maturity of the principal of any such Security;
<PAGE>   64
                                      -58-


                  (2) alter the optional redemption or repurchase provisions of
         any such Security or this Indenture in a manner adverse to the Holders
         of such Security;

                  (3) reduce the principal amount of any such Security;

                  (4) reduce the rate of or extend the time for payment of
         interest on any such Security;

                  (5) change the place or currency of payment of the principal
         of or interest on any such Security;

                  (6) modify any provisions of Section 6.04 (other than to add
         sections of this Indenture or the Securities subject thereto) or 6.07
         or this Section 9.02 (other than to add sections of this Indenture or
         the Securities which may not be amended, supplemented or waived without
         the consent of each Securityholder affected);

                  (7) reduce the percentage of the principal amount of
         outstanding Securities necessary for amendment to or waiver of
         compliance with any provision of this Indenture or the Securities or
         for waiver of any Default in respect thereof;

                  (8) waive a default in the payment of the principal of or
         interest on or redemption payment with respect to any such Security
         (except a rescission of acceleration of the Securities by the Holders
         as provided in Section 6.02 and a waiver of the payment default that
         resulted from such acceleration);

                  (9) modify the ranking or priority of such Security;

                  (10) modify the provisions of any covenant (or the related
         definitions in this Indenture) requiring the Company to make any Offer
         to Purchase in a manner materially adverse to the Holders; or

                  (11) modify the provisions of the Escrow Agreement or this
         Indenture relating to the Collateral from the Lien under the Escrow
         Agreement or permit any other obligation to be secured by the
         Collateral.

                  It shall not be necessary for the consent of the Holders under
this Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                  After an amendment, supplement or waiver under this Section
9.02 becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03.  Compliance with Trust Indenture Act.

                  Every amendment to or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.
<PAGE>   65
                                      -59-


SECTION 9.04.  Revocation and Effect of Consents.

                  Until an amendment or waiver becomes effective, a consent to
it by a Holder is a continuing consent by the Holder and every subsequent Holder
of that Security or portion of that Security that evidences the same debt as the
consenting Holder's Security, even if notation of the consent is not made on any
Security. Subject to the following paragraph, any such Holder or subsequent
Holder may revoke the consent as to such Holder's Security or portion of such
Security by notice to the Trustee or the Company received before the date on
which the Trustee receives an Officers' Certificate certifying that the Holders
of the requisite principal amount of Securities have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders of Securities entitled to
consent to any amendment, supplement or waiver. If a record date is fixed, then,
notwithstanding the last sentence of the immediately preceding paragraph, those
persons who were Holders of Securities at such record date (or their duly
designated proxies), and only those persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously given,
whether or not such persons continue to be Holders of such Securities after such
record date. No such consent shall be valid or effective for more than 90 days
after such record date.

                  After an amendment, supplement or waiver becomes effective, it
shall bind every Securityholder, unless it makes a change described in any of
clauses (1) through (11) of Section 9.02. In that case the amendment, supplement
or waiver shall bind each Holder of a Security who has consented to it and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security.

SECTION 9.05.  Notation on or Exchange of Securities.

                  If an amendment, supplement or waiver changes the terms of a
Security, the Trustee may require the Holder of the Security to deliver it to
the Trustee. The Trustee may place an appropriate notation on the Security about
the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Security shall issue
and the Trustee shall authenticate a new Security that reflects the changed
terms. Failure to make the appropriate notation or issue a new Security shall
not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06.  Trustee to Sign Amendments, etc.

                  The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article Nine is
authorized or permitted by this Indenture and that such amendment, supplement or
waiver constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms (subject to customary exceptions). The
Trustee may, but shall not be obligated to, execute any such amendment,
supplement or waiver which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise. In signing any amendment,
supplement or waiver, the Trustee shall be entitled to receive an indemnity
reasonably satisfactory to it.

applicable, be governed by such provisions. If any provision of this Indenture
modifies any TIA provision that may be so modified, such TIA provision shall be
deemed to apply to this Indenture as so modified. If any provision of this
Indenture excludes any TIA provision that may be so excluded, such TIA provision
shall be excluded from this Indenture.

                  The provisions of TIA Sections 310 through 317 that

The Company further agrees to take any and all action, including the execution

the basis contemplated herein shall, by written notice to the Trustee, designate
such additional or alternative agent for service of process under this Section
10.14 that (i) maintains an office located in the Borough of Manhattan, City of

provided in the Escrow Agreement which the Company and the Trustee have entered

required by the provisions of the Escrow Agreement, to assure and confirm to the

Agreement or any part thereof, as from time to time constituted, so as to render
the same available for the security and benefit of this Indenture with respect
to, and of, the Securities, according to the intent and purposes expressed in
the Escrow Agreement. The Company shall take any and all actions reasonably
required to cause the Escrow Agreement to create and maintain (to the extent
possible under applicable law), as security for the obligations of the Company
hereunder, a first priority and exclusive security interest in and on all the
Collateral, in favor of the Trustee for the benefit of the Holders of
Securities, superior to and prior to the rights of all third Persons and subject
to no other Liens. The Trustee shall have no responsibility for perfecting or
maintaining the perfection of the Trustee's security interest in the Collateral
or for filing any instrument, document or notice in any public office at any
time or times.

respect to the recording, registering and filing of this Indenture, financing
statements or other instruments necessary to make effective the security
interest intended to be created by the Escrow Agreement and reciting the details
of such action, or (ii) stating that in the opinion of such counsel no such
action is necessary to make such security interest effective.

                  (b) The Company shall furnish to the Trustee on each
anniversary of the Issue Date (upon receipt of written notice from Escrow Agent)
until the date upon which the balance of Escrow Funds shall have been reduced to
zero, an Opinion of Counsel, dated as of such date, either (i) stating that (A)
in the opinion of such counsel, action has been taken with respect to the
recording, registering, filing, re-recording, re-registering and refiling of all
supplemental indentures, financing statements, continuation statements or other
instruments of further assurance as is necessary to maintain the Lien of the
Escrow Agreement and reciting the details of such action or referring to prior
Opinions of Counsel in which such details are given and (B) based on relevant
laws as in effect on the date of such Opinion of Counsel, all financing
statements and continuation statements have been executed and filed that are
necessary as of such date and during the succeeding 12 months fully to preserve
and protect, to the extent such protection and preservation are possible by
filing, the rights of the Holders of Securities and the Trustee hereunder and
under the Escrow Agreement with respect to the security interests in the
Collateral or (ii) stating that, in the opinion of such counsel, no such action
is necessary to maintain such Lien and assignment.


SECTION 11.03.  Release of Collateral.

                  (a) Subject to subsections (b), (c) and (d) of this Section
11.03, the Collateral may be released from the security interest created by the
Escrow Agreement only in accordance with the provisions of the Escrow Agreement.

                  (b) Except to the extent that any security interest on
proceeds of Collateral is automatically released by operation of Section 9-306
of the Uniform Commercial Code or other similar law, no Collateral shall be
released from the security interest created by the Escrow Agreement pursuant to
the provisions of the Escrow Agreement, other than to the Holders pursuant to
the terms thereof.

                  (c) At any time when an Event of Default shall have occurred
and be continuing and the maturity of the Securities shall have been accelerated
(whether by declaration or otherwise), no Collateral shall be released pursuant
to the provisions of the Escrow Agreement, and no release of Collateral in
contravention of this Section 11.03(c) shall be effective as against the Holders
of Securities, except for the disbursement of all Escrow Funds (as defined in
the Escrow Agreement) and other Collateral to the Trustee pursuant to Section
6(c) of the Escrow Agreement.

                  (d) The release of any Collateral from the security interests
created by this Indenture and the Escrow Agreement shall not be deemed to impair
the security under this Indenture in contravention of the provisions hereof if
and to the extent the Collateral is released pursuant to the terms hereof or
pursuant to the terms of the Escrow Agreement. To the extent applicable, the
Company shall cause TIA Section 314(d) relating to the release of property or
securities from the security interest of the Escrow Agreement to be complied
with. Any certificate or opinion required by TIA Section 314(d) may be made by
an Officer of the Company except in cases where TIA Section 314(d) requires that
such certificate or opinion be made by an independent Person, which Person shall
be an independent engineer, appraiser or other expert selected or approved by
the Trustee in the exercise of reasonable care.

SECTION 11.04. Authorization of Actions to Be Taken by the Trustee Under the
Escrow Agreement.

                  Subject to the provisions of Section 7.01 and Section 7.02,
the Trustee may, without the consent of the Holders of Securities, on behalf of
the Holders of Securities, take all actions it deems necessary or appropriate in
order to (a) enforce any of the terms of the Escrow Agreement and (b) collect
and receive any
<PAGE>   73
                                      -67-


and all amounts payable in respect of the obligations of the Company hereunder.
The Trustee shall have power to institute and maintain such suits and
proceedings as it may deem expedient to prevent any impairment of the Collateral
by any acts that may be unlawful or in violation of the Escrow Agreement or this
Indenture, and such suits and proceedings as the Trustee may deem expedient to
preserve or protect its interests and the interests of the Holders of Securities
in the Collateral (including power to institute and maintain suits or
proceedings to restrain the enforcement of or compliance with any legislative or
other governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the security interest hereunder or be prejudicial to
the interests of the Holders of Securities or of the Trustee).

SECTION 11.05. Authorization of Receipt of Funds by the Trustee Under the Escrow
Agreement.

                  The Trustee is authorized to receive any funds for the benefit
of the Holders of Securities disbursed under the Escrow Agreement, and to make
further distributions of such funds to the Holders of Securities according to
the provisions of this Indenture.

SECTION 11.06.  Termination of Security Interest.

                  Upon the earliest to occur of (i) the date upon which the
balance of Escrow Funds and other Collateral shall have been reduced to zero,
(ii) the payment of the first four scheduled interest payments on the
Securities, (iii) legal defeasance pursuant to Section 8.01 and (iv) covenant
defeasance pursuant to Section 8.01, the Trustee shall, at the written request
of the Company, release the security interest in the Collateral pursuant to this
Indenture and the Escrow Agreement upon the Company's compliance with the

                           HERMES EUROPE RAILTEL B.V.


                          11-1/2% Senior Note due 2007


1.       Interest.

                  HERMES EUROPE RAILTEL B.V., a Netherlands limited company (the
"Company"), promises to pay interest on the principal amount of this Security at
the rate per annum shown above. Cash interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from August 19, 1997. The Company will pay interest semi-annually in
arrears on each Interest Payment Date, commencing February 15, 1998. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

                  The Company shall pay interest on overdue principal from time
to time on demand at the rate borne by the Securities and on overdue
installments of interest (without regard to any applicable grace periods) at the
rate borne by the Securities to the extent lawful.

2.       Method of Payment.

                  The Company shall pay interest on the Securities (except
defaulted interest) to the persons who are the registered Holders at the close
of business on the Interest Record Date immediately preceding the Interest
Payment Date even if the Securities are cancelled on registration of transfer or
registration of exchange after such Interest Record Date. Holders must surrender
Securities to a Paying Agent to collect principal payments. The Company shall
pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts ("U.S. Legal
Tender"). However, the Company may pay principal and interest by wire transfer
of Federal funds (provided that the Paying Agent shall have received wire
instructions on or prior to the relevant Interest Record Date), or interest by
check payable in such U.S. Legal Tender. The Company may deliver any such
interest payment to the Paying Agent or to a Holder at the Holder's registered
address.

3.       Paying Agent and Registrar.

                  Initially, The Bank of New York (the "Trustee") will act as
Paying Agent and Registrar in the Borough of Manhattan, The City of New York,
and Banque Internationale a Luxembourg S.A. will act as Paying Agent and
Registrar in Luxembourg. The Company may change any Paying Agent or Registrar
without notice to the Holders. The Company or any of its Subsidiaries may,
subject to certain exceptions, act as Registrar.

4.       Indenture.

                  The Company issued the Securities under an Indenture, dated as
of August 19, 1997 (the "Indenture"), among the Company, Global TeleSystems
Group, Inc. and the Trustee. Capitalized terms herein are used as defined in the
Indenture unless otherwise defined herein. The terms of the Securities include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture


                                      A-5
<PAGE>   80
Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the "TIA"), as in effect on
the date of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. Notwithstanding anything to the contrary herein, the
Securities are subject to all such terms, and holders of Securities are referred
to the Indenture and the TIA for a statement of them. This is one of the Series
A Securities referred to in the Indenture. The Series A Securities and the
Series B Securities referred to in the Indenture are general obligations of the
Company limited in aggregate principal amount to $265,000,000.

5.       Optional Redemption.

         (a) The Securities will be redeemable at the option of the Company, in
whole or in part, at any time or from time to time, on or after August 15, 2002
at the redemption prices (expressed as a percentage of principal amount) set

date if redeemed during the twelve-month period commencing on of the years set

</TABLE>

         (b) Redemption Upon Public Equity Offering or Strategic Equity
Investment.

                  At any time, or from time to time, prior to August 15, 2000,
the Company may redeem Securities at a redemption price equal to 111.5% of the
principal amount of the Securities so redeemed, plus accrued and unpaid interest
thereon, if any, to the redemption date, with the net cash proceeds of one or
more Public Equity Offerings or Strategic Equity Investments resulting in
aggregate gross cash proceeds to the Company of at least $75 million; provided,
however, that at least two-thirds of the principal amount of Securities
originally issued would remain outstanding immediately after giving effect to
any such redemption (excluding any Securities owned by the Company or any of its
Affiliates) (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 the last Public Equity Offering
or Strategic Equity Investment resulting in gross cash proceeds to the Company,
when aggregated with all prior Public Equity Offerings and Strategic Equity
Investments, of at least $75.0 million.

         (c) Redemption for Changes in Withholding Taxes.

                  The Company may, at any time, at its option, redeem all (but
not less than all) of the Securities 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 Securities,
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.

<PAGE>   81
6.       Notice of Redemption.

                  Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Securities to be redeemed at its registered address; provided,
however, that notice of redemption pursuant to paragraph 5(b) of this Security
will be mailed to each Holder of Securities to be redeemed no later than 60 days
following the consummation of the last Public Equity Offering resulting in gross
cash proceeds to the Company, when aggregated with all prior Public Equity
Offerings, of at least $75.0 million. The Trustee may select for redemption
portions of the principal amount of Securities that have denominations equal to
or larger than $1,000 principal amount. Securities and portions of them the
Trustee so selects shall be in amounts of $1,000 principal amount or integral
multiples thereof.

                  If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption so long as the Company has deposited with the Paying Agent for the
Securities funds in satisfaction of the redemption price pursuant to the
Indenture.

7.       Change of Control Offer.

                  Upon the occurrence of a Change of Control, the Company will
be required to offer to purchase all outstanding Securities at a purchase price
in cash equal to 101% of the aggregate principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the Purchase Date.

8.       Limitation on Disposition of Assets.

                  Upon the occurrence of certain Asset Sales, the Company is,
subject to certain conditions, obligated to make an offer to purchase Securities
at a purchase price in cash equal to 100% of the aggregate principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the Purchase Date.

9.       Denominations; Transfer; Exchange.

                  The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

10.      Persons Deemed Owners.

                  The registered Holder of a Security shall be treated as the
owner of it for all purposes.

<PAGE>   82
11.      Unclaimed Funds.

                  If funds for the payment of principal or interest remain
unclaimed for two years, the Trustee and the Paying Agent will repay the funds
to the Company at its written request. After that, all liability of the Trustee
and such Paying Agent with respect to such funds shall cease.

12.      Legal Defeasance and Covenant Defeasance.

                  The Company may be discharged from its obligations under the
Indenture and the Securities except for certain provisions thereof, and may be
discharged from obligations to comply with certain covenants contained in the
Indenture and the Securities, in each case upon satisfaction of certain
conditions specified in the Indenture.

13.      Amendment; Supplement; Waiver.

                  Subject to certain exceptions, the Indenture and the
Securities may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or compliance with any provision may
be waived with the consent of the Holders of a majority in aggregate principal
amount of the Securities then outstanding. Without notice to or consent of any
Holder, the parties thereto may amend or supplement the Indenture and the
Securities to, among other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Securities in addition to or in place of certificated
Securities, effect the assumption by a successor person of all obligations of
the Company under Securities, the Indenture, the Registration Rights Agreement
and the Escrow Agreement in connection with any transaction complying with
Article Five of the Indenture or comply with any requirements of the SEC in
connection with the qualification of the Indenture under the TIA, or make any
other change that does not materially adversely affect the rights of any Holder
of a Security.

14.      Restrictive Covenants.

                  The Indenture contains certain covenants that, among other
things, limit the ability of the Company and the Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to create liens, to sell assets, to
permit restrictions on dividends and other payments to become applicable to
Restricted Subsidiaries, to consolidate, merge or sell all or substantially all
of its assets, to engage in transactions with affiliates or certain other
related persons. The limitations are subject to a number of important
qualifications and exceptions. The Company must annually report to the Trustee
on compliance with such limitations.

15.      Defaults and Remedies.

                  If an Event of Default (other than certain events of
bankruptcy, insolvency or reorganization affecting the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Securities then outstanding by notice in writing to the Company may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture. If certain events of bankruptcy,
insolvency or reorganization affecting the Company occur under the Indenture,
the Securities will ipso facto become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder of Securities.
Holders of Securities may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee is not obligated to enforce the Indenture
or the Securities unless it has received indemnity reasonably satisfactory to
it. The Indenture permits, subject to certain limitations therein provided,
Holders of a majority in aggregate principal amount of the Securities then
outstanding


                                      A-8
<PAGE>   83
to direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of Securities notice of certain continuing Defaults if it
determines that withholding notice is in their interest.

16.      Trustee Dealings with Company.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company, its Subsidiaries or their respective Affiliates as if it
were not the Trustee.

17.      No Recourse Against Others.

                  No stockholder, director, officer, employee or incorporator,
as such, of the Company or any of its Affiliates shall have any liability for
any obligation of the Company or any of its Affiliates under the Securities or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of a Security by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities.

18.      Authentication.

                  This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

19.      Abbreviations and Defined Terms.

                  Customary abbreviations may be used in the name of a Holder of
a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

20.      CUSIP Numbers.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the
Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other
identification numbers printed hereon.

21.      Governing Law.

                  The laws of the State of New York shall govern the Indenture
and this Security without regard to principles of conflicts of laws.

                           HERMES EUROPE RAILTEL B.V.


                     11-1/2% Senior Note due 2007, Series B


1.       Interest.

                  HERMES EUROPE RAILTEL B.V., a Netherlands limited company (the
"Company"), promises to pay interest on the principal amount of this Security at
the rate per annum shown above. Cash interest on the Securities will accrue from
the most recent date to which interest has been paid or, if no interest has been
paid, from August 19, 1997. The Company will pay interest semi-annually in
arrears on each Interest Payment Date, commencing February 15, 1998. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

                  The Company shall pay interest on overdue principal from time
to time on demand at the rate borne by the Securities and on overdue
installments of interest (without regard to any applicable grace periods) at the
rate borne by the Securities to the extent lawful.

2.       Method of Payment.

                  The Company shall pay interest on the Securities (except
defaulted interest) to the persons who are the registered Holders at the close
of business on the Interest Record Date immediately preceding the Interest
Payment Date even if the Securities are cancelled on registration of transfer or
registration of exchange after such Interest Record Date. Holders must surrender
Securities to a Paying Agent to collect principal payments. The Company shall
pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts ("U.S. Legal
Tender"). However, the Company may pay principal and interest by wire transfer
of Federal funds (provided that the Paying Agent shall have received wire
instructions on or prior to the relevant Interest Record Date), or interest by
check payable in such U.S. Legal Tender. The Company may deliver any such
interest payment to the Paying Agent or to a Holder at the Holder's registered
address.

3.       Paying Agent and Registrar.

                  Initially, The Bank of New York (the "Trustee") will act as
Paying Agent and Registrar in the Borough of Manhattan, The City of New York,
and Banque Internationale a Luxembourg S.A. will act as Paying Agent and
Registrar in Luxembourg. The Company may change any Paying Agent or Registrar
without notice to the Holders. The Company or any of its Subsidiaries may,
subject to certain exceptions, act as Registrar.

4.       Indenture.

                  The Company issued the Securities under an Indenture, dated as
of August 19, 1997 (the "Indenture"), among the Company, Global TeleSystems
Group, Inc. and the Trustee. Capitalized terms herein are used as defined in the
Indenture unless otherwise defined herein. The terms of the Securities include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture


                                      B-3
<PAGE>   89
Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the "TIA"), as in effect on
the date of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. Notwithstanding anything to the contrary herein, the
Securities are subject to all such terms, and holders of Securities are referred
to the Indenture and the TIA for a statement of them. This is one of the Series
A Securities referred to in the Indenture. The Series A Securities and the
Series B Securities referred to in the Indenture are general obligations of the
Company limited in aggregate principal amount to $265,000,000.

5.       Optional Redemption.

         (a) The Securities will be redeemable at the option of the Company, in
whole or in part, at any time or from time to time, on or after August 15, 2002

</TABLE>

         (b) Redemption Upon Public Equity Offering or Strategic Equity
Investment.

                  At any time, or from time to time, prior to August 15, 2000,
the Company may redeem Securities at a redemption price equal to 111.5% of the
principal amount of the Securities so redeemed, plus accrued and unpaid interest
thereon, if any, to the redemption date, with the net cash proceeds of one or
more Public Equity Offerings or Strategic Equity Investments resulting in
aggregate gross cash proceeds to the Company of at least $75 million; provided,
however, that at least two-thirds of the principal amount of Securities
originally issued would remain outstanding immediately after giving effect to
any such redemption (excluding any Securities owned by the Company or any of its
Affiliates) (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 the last Public Equity Offering
or Strategic Equity Investment resulting in gross cash proceeds to the Company,
when aggregated with all prior Public Equity Offerings and Strategic Equity
Investments, of at least $75.0 million.

         (c)  Redemption for Changes in Withholding Taxes.

                  The Company may, at any time, at its option, redeem all (but
not less than all) of the Securities 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 Securities,
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.

<PAGE>   90
6.       Notice of Redemption.

                  Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the Redemption Date to each
Holder of Securities to be redeemed at its registered address; provided,
however, that notice of redemption pursuant to paragraph 5(b) of this Security
will be mailed to each Holder of Securities to be redeemed no later than 60 days
following the consummation of the last Public Equity Offering resulting in gross
cash proceeds to the Company, when aggregated with all prior Public Equity
Offerings, of at least $75.0 million. The Trustee may select for redemption
portions of the principal amount of Securities that have denominations equal to
or larger than $1,000 principal amount. Securities and portions of them the
Trustee so selects shall be in amounts of $1,000 principal amount or integral
multiples thereof.

                  If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption so long as the Company has deposited with the Paying Agent for the
Securities funds in satisfaction of the redemption price pursuant to the
Indenture.

7.       Change of Control Offer.

                  Upon the occurrence of a Change of Control, the Company will
be required to offer to purchase all outstanding Securities at a purchase price
in cash equal to 101% of the aggregate principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the Purchase Date.

8.       Limitation on Disposition of Assets.

                  Upon the occurrence of certain Asset Sales, the Company is,
subject to certain conditions, obligated to make an offer to purchase Securities
at a purchase price in cash equal to 100% of the aggregate principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the Purchase Date.

9.       Denominations; Transfer; Exchange.

                  The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000. A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

10.      Persons Deemed Owners.

                  The registered Holder of a Security shall be treated as the
owner of it for all purposes.

<PAGE>   91
11.      Unclaimed Funds.

                  If funds for the payment of principal or interest remain
unclaimed for two years, the Trustee and the Paying Agent will repay the funds
to the Company at its written request. After that, all liability of the Trustee
and such Paying Agent with respect to such funds shall cease.

12.      Legal Defeasance and Covenant Defeasance.

                  The Company may be discharged from its obligations under the
Indenture and the Securities except for certain provisions thereof, and may be
discharged from obligations to comply with certain covenants contained in the
Indenture and the Securities, in each case upon satisfaction of certain
conditions specified in the Indenture.

13.      Amendment; Supplement; Waiver.

                  Subject to certain exceptions, the Indenture and the
Securities may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or compliance with any provision may
be waived with the consent of the Holders of a majority in aggregate principal
amount of the Securities then outstanding. Without notice to or consent of any
Holder, the parties thereto may amend or supplement the Indenture and the
Securities to, among other things, cure any ambiguity, defect or inconsistency,
provide for uncertificated Securities in addition to or in place of certificated
Securities, effect the assumption by a successor person of all obligations of
the Company under Securities, the Indenture, the Registration Rights Agreement
and the Escrow Agreement in connection with any transaction complying with
Article Five of the Indenture or comply with any requirements of the SEC in
connection with the qualification of the Indenture under the TIA, or make any
other change that does not materially adversely affect the rights of any Holder
of a Security.

14.      Restrictive Covenants.

                  The Indenture contains certain covenants that, among other
things, limit the ability of the Company and the Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to create liens, to sell assets, to
permit restrictions on dividends and other payments to become applicable to
Restricted Subsidiaries, to consolidate, merge or sell all or substantially all
of its assets, to engage in transactions with affiliates or certain other
related persons. The limitations are subject to a number of important
qualifications and exceptions. The Company must annually report to the Trustee
on compliance with such limitations.

15.      Defaults and Remedies.

                  If an Event of Default (other than certain events of
bankruptcy, insolvency or reorganization affecting the Company) occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Securities then outstanding by notice in writing to the Company may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture. If certain events of bankruptcy,
insolvency or reorganization affecting the Company occur under the Indenture,
the Securities will ipso facto become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder of Securities.
Holders of Securities may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee is not obligated to enforce the Indenture
or the Securities unless it has received indemnity reasonably satisfactory to
it. The Indenture permits, subject to certain limitations therein provided,
Holders of a majority in aggregate principal amount of the Securities then
outstanding


                                      B-6
<PAGE>   92
to direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of Securities notice of certain continuing Defaults if it
determines that withholding notice is in their interest.

16.      Trustee Dealings with Company.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities and may otherwise
deal with the Company, its Subsidiaries or their respective Affiliates as if it
were not the Trustee.

17.      No Recourse Against Others.

                  No stockholder, director, officer, employee or incorporator,
as such, of the Company or any of its Affiliates shall have any liability for
any obligation of the Company or any of its Affiliates under the Securities or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of a Security by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Securities.

18.      Authentication.

                  This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

19.      Abbreviations and Defined Terms.

                  Customary abbreviations may be used in the name of a Holder of
a Security or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

20.      CUSIP Numbers.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Securities as a convenience to the Holders of the
Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other
identification numbers printed hereon.

21.      Governing Law.

                  The laws of the State of New York shall govern the Indenture
and this Security without regard to principles of conflicts of laws.

                    OR REGISTRATION OF TRANSFER OF SECURITIES

         Re:      11-1/2% Senior Notes due 2007
                  (the "Securities"), of Hermes Europe Railtel B.V.

                  This Certificate relates to $_______ principal amount of
Securities held in the form of* ___ a beneficial interest in a Global Security
or* _______ Physical Securities by_____________________ (the "Transferor").

The Transferor:*

         |_| has requested by written order that the Registrar deliver in
exchange for its beneficial interest in the Global Security held by the
Depositary a Physical Security or Physical Securities in definitive, registered
form of authorized denominations and an aggregate number equal to its beneficial
interest in such Global Security (or the portion thereof indicated above); or

         |_| has requested that the Registrar by written order to exchange or
register the transfer of a Physical Security or Physical Securities.

                  In connection with such request and in respect of each such
Security, the Transferor does hereby certify that the Transferor is familiar
with the Indenture relating to the above captioned Securities and the
restrictions on transfers thereof as provided in Section 2.06 of such Indenture,
and that the transfer of the Securities does not require registration under the
Securities Act of 1933, as amended (the "Act"), because*:

         |_| Such Security is being acquired for the Transferor's own account,
without transfer (in satisfaction of Section 2.06 of the Indenture).

         |_| Such Security is being transferred to a "qualified institutional
buyer" (as defined in Rule 144A under the Act), in reliance on Rule 144A.

investor" (within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule
501 under the Act) which delivers a certificate to the Trustee in the form of
Exhibit E to the Indenture. An opinion of counsel to the effect that such
transfer does not require registration under the Securities Act accompanies this
certification.

         |_| Such Security is being transferred in reliance on Regulation S
under the Act. An opinion of counsel to the effect that such transfer does not
require registration under the Securities Act accompanies this certification.

         |_| Such Security is being transferred in reliance on Rule 144 under
the Act. An opinion of counsel to the effect that such transfer does not require
registration under the Securities Act accompanies this certification.

         |_| Such Security is being transferred in reliance on and in compliance
with an exemption from the registration requirements of the Act other than Rule
144A or Rule 144 or Regulation S under the Act to a person other than an
institutional "accredited investor." An opinion of counsel to the effect that
such transfer does not require registration under the Securities Act accompanies
this certification.

                  Senior Notes due 2007


Ladies and Gentlemen:

                  In connection with our proposed purchase of $ aggregate
principal amount of 11-1/2% Senior Notes due 2007 (the "Notes") of Hermes Europe
Railtel B.V., a Netherlands limited company (the "Company"), we confirm that:

                  1. We understand that the Notes have not been registered under
             the Securities Act of 1933, as amended (the "Securities Act"), and
             may not be sold except as permitted in the following sentence. We
             understand and agree, on our own behalf and on behalf of any
             accounts for which we are acting as hereinafter stated, (x) that
             such Notes are being offered only in a transaction not involving
             any public offering within the meaning of the Securities Act and
             (y) that if we decide to resell, pledge or otherwise transfer such
             Notes within two years after the date of the original issuance of
             the Notes or if within three months after we cease to be an
             affiliate (within the meaning of Rule 144 under the Securities Act)
             of the Company, such Notes may be resold, pledged or transferred
             only (i) to the Company, (ii) so long as the Notes are eligible for
             resale pursuant to Rule 144A under the Securities Act ("Rule
             144A"), to a person whom we reasonably believe is a "qualified
             institution buyer" (as defined in Rule 144A) ("QIB") that purchases
             for its own account or for the account of a QIB to whom notice is
             given that the resale, pledge or transfer is being made in reliance
             on Rule 144A (as indicated by the box checked by the transferor on
             the Certificate of Transfer on the reverse of the certificate for
             the Notes), (iii) in an offshore transaction in accordance with
             Regulation S under the Securities Act (as indicated by the box
             checked by the transferor on the Certificate of Transfer on the
             reverse of the Note if the Note is not in book-entry form), and, if
             such transfer is being effected by certain transferors prior to the
             expiration of the "40 day restricted period" (within the meaning of
             Rule 903(c)(2) of Regulation S under the Securities Act), a
             certificate that my be obtained from the Trustee is delivered by
             the transferee, (iv) to an institution that is an "accredited
             investor" as defined in Rule 501(a)(1), (2), (3) or (7) under the
             Securities Act (as indicated by the box checked by the transferor
             on the Certificate of Transfer on the reverse of the certificate
             for the Notes) which has certified to the Company and the Trustee
             for the Notes that it is such an accredited investor and is
             acquiring the Notes for investment purposes and not for
             distribution (provided that no Notes purchased from a foreign
             purchaser or from any person other than a QIB or an institutional
             accredited investor pursuant to this clause (iii) shall be
             permitted to transfer any Notes so purchased to an institutional
             accredited investor pursuant to this

             period" (within the meaning of Regulation S under the Securities
             Act)), (v) pursuant to an exemption from registration under the
             Securities Act provided by Rule 144 (if applicable) under the
             Securities Act, or (vi) pursuant to an effective registration
             statement under the Securities Act, in each case in accordance with
             any applicable securities laws of any state of the United States,
             and we will notify any purchaser of the Notes from us of the above
             resale restriction, if then applicable. We further understand that
             in connection with any transfer of the Notes by us that the Company
             and the Trustee for the Notes may request, and if so requested we
             will furnish, such certificates, legal opinions and other
             information as they may reasonably require to confirm that any such
             transfer complies with the foregoing restrictions.

                  2. We are able to fend for ourselves in the transactions
             contemplated by this Offering Memorandum, we have such knowledge
             and experience in financial and business matters as to be capable
             of evaluating the merits and risks of our investment in the Notes,
             and we and any accounts for which we are acting are each able to
             bear the economic risk of our or its investment and can afford the
             complete loss of such investment.

                  3. We understand that the minimum principal amount of Notes
             that may be purchased by an investor is $250,000.

                  4. We understand that the Company, Donaldson, Lufkin &
             Jenrette Securities Corporation, UBS Securities LLC and Lehman
             Brothers Inc., as the initial purchasers of the Securities
             ("Initial Purchasers"), and others will rely upon the truth and
             accuracy of the foregoing acknowledgments, representations and
             agreements and we agree that if any of the acknowledgments,
             representations and warranties deemed to have been made by us by
             our purchase of Notes, for our own account or of one or more
             accounts as to each of which we exercise sole investment
             discretion, are no longer accurate, we shall promptly notify the
             Company and the Initial Purchasers.

                  5. We are acquiring the Notes purchased by us for investment
             purposes and not for distribution of our own account or for one or
             more accounts as to each of which we exercise sole investment
             discretion and we are or such account is an institutional

indenture that 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 TIA) and
that 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
Offer will be registered under the Securities Act on the appropriate form (the
"Exchange Offer Registration Statement") and will comply with all applicable
tender offer rules and regulations under the Exchange Act. The Company agrees to
use its reasonable best efforts (i) to cause the Exchange Offer Registration
Statement to become effective and to commence the Exchange Offer on or prior to
the Effectiveness Date, (ii) to keep the Exchange Offer open for 30 days (or
longer if required by applicable law) (the last day of such period, the

validly tendered and not withdrawn pursuant to the Exchange Offer on or prior to

deemed to represent that any Exchange Securities received by it will be acquired
in the ordinary course of its business, that at the time of the consummation of
the Exchange Offer such Holder will have no arrangement with any person to
participate in the distribution of the Exchange Securities in violation of the
provisions of the Securities Act, and that such Holder is not an affiliate of
the Company within the meaning of the Securities Act.

                  Upon consummation of the Exchange Offer in accordance with
this Section 2, the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to Registrable Securities that are Private
Exchange Securities, Exchange Securities to which Section 2(c)(v) is applicable
and Exchange Securities held by Participating Broker-Dealers, and the Company
shall have no further obligation to register Registrable Securities (other than
Private Exchange Securities and other than Exchange Securities as to which
Section 2(c)(v) hereof applies) pursuant to Section 3 of this Agreement. No
Securities other than the Exchange Securities shall be included in the Exchange
Offer Registration Statement.

                  (b) The Company shall include within the Prospectus contained
in the Exchange Offer Registration Statement a Section entitled "Plan of
Distribution," reasonably acceptable to the Initial Purchasers, which
<PAGE>   6
                                      -5-

shall contain a summary statement of the positions taken or policies made by the
Staff of the Commission (and publicly disseminated) with respect to the
potential "underwriter" status of any broker-dealer that is the beneficial owner
(as defined in Rule 13d-3 under the Exchange Act) of Exchange Securities
received by such broker-dealer in the Exchange Offer (a "Participating
Broker-Dealer"). Such "Plan of Distribution" section shall also allow the use of
the prospectus by all persons subject to the prospectus delivery requirements of
the Securities Act, including all Participating Broker-Dealers, and include a
statement describing the means by which Participating Broker-Dealers may resell
the Exchange Securities.

                  The Company shall use its reasonable best efforts to keep the
Exchange Offer 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 following the first bona fide offering of
securities under such Registration Statement (or such shorter time as such
persons must comply with such requirements in order to resell the Exchange
Securities) (the "Applicable Period").

                  If, prior to consummation of the Exchange Offer, the Initial
Purchasers hold any Notes acquired by them and having, or which are reasonably
likely to be determined to have, the status of an unsold allotment in the
initial distribution, the Company upon the request of the Initial Purchasers
shall, simultaneously with the delivery of the Exchange Securities in the
Exchange Offer, issue and deliver to the Initial Purchasers, in exchange (the
"Private Exchange") for the Notes held by the Initial Purchasers, a like
principal amount of debt securities of the Company that are identical to the
Exchange Securities (the "Private Exchange Securities") (and which are issued
pursuant to the same indenture as the Exchange Securities) (except for the
placement of a restrictive legend on such Private Exchange Securities). The
Private Exchange Securities shall bear the same CUSIP number as the Exchange
Securities. Interest on the Exchange Securities and Private Exchange Securities
will accrue from the last interest payment date on which interest was paid on
the Notes surrendered in exchange therefor or, if no interest has been paid on
the Notes, from the Issue Date.

                  Any indenture under which the Exchange Securities or the
Private Exchange Securities will be issued shall provide that the holders of any
of the Exchange Securities and the Private Exchange Securities will vote and
consent together on all matters to which such holders are entitled to vote or
consent as one class and that none of the holders of the Exchange Securities and
the Private Exchange Securities will have the right to vote or consent as a
separate class on any matter.

                  (c) 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, for any
reason, not consummated on or prior to the 165th day after the Issue Date, (iv)
any Holder of Private Exchange Securities so requests, or (v) in the case of any
Holder that 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 Section 3.

3.    SHELF REGISTRATION

                  If a Shelf Registration Event has occurred (and whether or not
an Exchange Offer Registration Statement has been filed with the Commission or
has become effective, or the Exchange Offer has been consummated), then:
<PAGE>   7
                                      -6-



                  (a) 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 after which non-affiliates of the issuer are permitted to resell
securities 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").

                  (b) 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.

                  (c) 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.

                  (d)  Hold-Back Agreements.

                  (i) Restrictions on Public Sale by Holders of Registrable
         Securities. Each Holder of Registrable Securities whose Registrable
         Securities are covered by a Shelf Registration Statement (which
         Registrable Securities are not being sold in the underwritten offering
         described below) agrees, if requested (pursuant to a timely written
         notice) by the Company or by the managing underwriter or underwriters
         in an underwritten offering of Registrable Securities, not to effect
         any public sale or distribution of any securities within the class of
         securities covered by such Shelf Registration Statement or any similar
         class of securities of the Company, including a sale pursuant to Rule
         144 or Rule 144A (except as part of such underwritten offering), during
         the period beginning 10 days prior to, and ending 60 days after, the
         Issue Date of each underwritten offering made pursuant to each Shelf
         Registration Statement, to the
<PAGE>   8
                                      -7-



         extent timely notified in writing by the Company or by the managing
         underwriter or underwriters; provided, however, that each holder of
         Registrable Securities shall be subject to the hold-back restrictions
         of this Section 3(d)(i) only once during the term of this Agreement.

                  The foregoing provisions shall not apply to any Holder of
         Registrable Securities if such Holder is prevented by applicable
         statute or regulation from entering into any such agreement; provided,
         however, that any such Holder shall undertake, in its request to
         participate in any such underwritten offering, not to effect any public
         sale or distribution of the class of securities covered by such Shelf
         Registration Statement (except as part of such underwritten offering)
         during such period unless it has provided 45 days' prior written notice
         of such sale or distribution to the Company or the managing underwriter
         or underwriters, as the case may be.

                  (ii) Restrictions on the Company and Others. The Company
         agrees (A) not to effect any public or private sale or distribution
         (including, without limitation, a sale pursuant to Regulation D under
         the Securities Act) of any securities the same as or similar to those
         covered by a Shelf Registration Statement or any securities convertible
         into or exchangeable or exercisable for such securities, during the 10
         days prior to, and during the 60-day period beginning on, the
         commencement of an underwritten public distribution of Registrable
         Securities, where the managing underwriter or underwriters so requests
         pursuant to timely written notice; (B) to include in any agreements
         entered into by the Company on or after the date of this Agreement
         (other than any underwriting agreement relating to a public offering
         registered under the Securities Act) pursuant to which the Company
         issues or agrees to issue securities the same as or similar to the
         Notes a provision substantially identical to Section 3(d)(i); and (C)
         not to grant or agree to grant any "piggy-back registration" or other
         similar rights to any holder of the Company's or any of its
         subsidiaries' securities issued on or after the date of this Agreement
         with respect to any Registration Statement.

4.    ADDITIONAL INTEREST

                  (a) The Company and the Initial Purchasers agree that the
Holders of Notes will suffer damages if the Company fails to fulfill its
obligations under Section 2 or Section 3 hereof and that it would not be
feasible to ascertain the extent of such damages with precision. Accordingly,
the Company agrees to pay, as liquidated damages, additional interest on the
Notes ("Additional Interest") under the circumstances and to the extent set
forth below (each of which shall be given independent effect):

  (i)      if either the Exchange Offer Registration Statement or the Initial
           Shelf Registration Statement has not been filed on or prior to the
           Filing Date (unless, with respect to the Exchange Offer Registration
           Statement, a Shelf Registration Event described in Section 2(c)(i)
           shall have occurred prior to the Filing Date), Additional Interest
           shall accrue on the Notes over and above the stated interest on the
           principal of a rate equal to 50 basis points for the first 90 days
           (or any part thereof) immediately following such date, such
           Additional Interest rate increasing by an additional 50 basis points
           for each subsequent 90-day period (or any part thereof);

                     (ii) if either the Exchange Offer 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 Exchange Offer Registration Statement, a Shelf
           Registration Event described in Section 2(c)(i) 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 (or any part thereof) immediately
           fol-
<PAGE>   9
                                      -8-






         lowing the day after such date, such Additional Interest rate
         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 Exchange Offer 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) at a rate equal to 50 basis points
         for the first 90 days (or any part thereof) commencing on (x) the sixth
         day after the Expiration Date, in the case of (A) above, or (y) the day
         the Exchange Offer 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 rate increasing by an additional 50 basis points for 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
Section 4(a)), (2) upon the effectiveness of the Exchange Offer Registration
Statement or the Shelf Registration Statement as required hereunder (in the case
of clause (ii) of this Section 4(a)) or (3) upon the exchange of Exchange
Securities for all Notes validly tendered and not withdrawn (in the case of
clause (iii)(A) of this Section 4(a)), or upon the effectiveness of the Exchange
Offer Registration Statement which had ceased to remain effective (in the case
of clause (iii)(B) of this Section 4(a)), or upon the effectiveness of the Shelf
Registration Statement which had ceased to remain effective (in the case of
clause (iii)(C) of this Section 4(a)), 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).

                  (b) The Company shall notify the Trustee within one business
day after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). The Company shall
pay the Additional Interest due on the Registrable Securities by depositing with
the Trustee, in trust, for the benefit of the Holders thereof, on or before the
applicable semi-annual interest payment date, immediately available funds in
sums sufficient to pay the Additional Interest then due to Holders of
Registrable Securities. Each obligation to pay Additional Interest shall be
deemed to accrue immediately following the occurrence of the applicable Event
Date. Any accrued Additional Interest amount shall be due and payable on each
interest payment date immediately after the applicable Event Date to the record
Holder of Registrable Securities entitled to receive the interest payment to be
made on such date as set forth in the Indenture. The parties hereto agree that
the Additional Interest provided for in this Section 4 constitutes a reasonable
estimate of the damages that may be incurred by Holders of Registrable
Securities by reason of the failure of a Shelf Registration Statement or
Exchange Offer Registration Statement to be filed or declared effective, or a
Shelf Registration Statement to remain effective, as the case may be, in
accordance with this Section 4.

5.    REGISTRATION PROCEDURES

                  In connection with the registration of any Registrable
Securities pursuant to Sections 2 or 3 hereof, the Company shall use its
reasonable best efforts to effect such registrations to permit the sale of such
Registrable Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall:
<PAGE>   10
                                      -9-



                  (a) prepare and file with the Commission on or before the
Filing Date, a Registration Statement or Registration Statements as prescribed
by Section 2 or 3, and to use its reasonable best efforts to cause each such
Registration Statement to become effective and remain effective as provided
herein; provided, however, that, if (1) such filing is pursuant to Section 3, or
(2) a Prospectus contained in an Exchange Offer Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Securities during the
Applicable Period, before filing any Registration Statement or Prospectus or any
amendments or supplements thereto, the Company shall furnish to and afford the
Holders of the Registrable Securities and each such Participating Broker-Dealer,
as the case may be, covered by such Registration Statement, their counsel and
the managing underwriters, if any, a reasonable opportunity to review copies of
all such documents (including copies of any documents to be incorporated by
reference therein) proposed to be filed; the Company shall not file any
Registration Statement or Prospectus or any amendments or supplements thereto in
respect of which the Holders must be afforded a reasonable opportunity to review
prior to the filing of such document, if the Holders of a majority in aggregate
principal amount of the Registrable Securities covered by such Registration
Statement, or such Participating Broker-Dealer, as the case may be, their
counsel, or the managing underwriters, if any, shall not have been afforded such
opportunity or shall reasonably object, except for any amendment or supplement
or document that counsel to the Company shall advise the Company in writing is
required in order to comply with applicable law;

                  (b) prepare and file with the Commission such amendments and
post-effective amendments to each Shelf Registration Statement or Exchange Offer
Registration Statement, as the case may be, as may be necessary to keep such
Registration Statement continuously effective for the Effectiveness Period, in
the case of a Shelf Registration Statement, or until the later of the Expiration
Date and the Applicable Period (if applicable), in the case of the Exchange
Offer Registration Statement; cause the related Prospectus to be supplemented by
any required Prospectus supplement, and as so supplemented to be filed pursuant
to Rule 424 (or any similar provisions then in force) under the Securities Act;
and comply with the provisions of the Securities Act, the Exchange Act and the
rules and regulations of the Commission promulgated thereunder applicable to it
with respect to the disposition of all securities covered by such Registration
Statement as so amended or in such Prospectus as so supplemented and with
respect to the subsequent resale of any securities being sold by a Participating
Broker-Dealer covered by any such Prospectus;

                  (c) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, notify the selling Holders of
Registrable Securities, or each such Participating Broker-Dealer, as the case
may be, their counsel and the managing underwriters, if any, promptly, and
confirm such notice in writing, (i) when a Prospectus or any Prospectus
supplement or post-effective amendment has been filed, and, with respect to a
Registration Statement or any post-effective amendment, when the same has become
effective (including in such notice a written statement that any Holder may,
upon request, obtain, without charge, one conformed copy of such Registration
Statement or post-effective amendment including financial statements and
schedules, but without documents incorporated or deemed to be incorporated by
reference or exhibits unless specifically requested); (ii) of the issuance by
the Commission of any stop order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus or the initiation of any proceedings for that purpose; (iii) if at
any time when a prospectus is required by the Securities Act to be delivered in
connection with sales of the Registrable Securities the representations and
warranties of the Company contained in any agreement (including any underwriting
agreement) contemplated by Section 5(n) below cease to be true and correct; (iv)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of a Registration Statement
or any of the Registrable Securities or the Exchange Securities to be sold by
any Participating Broker-Dealer for offer or sale in any
<PAGE>   11
                                      -10-

jurisdiction, or the initiation or threatening of any proceeding for such
purpose; (v) of the happening of any event or any information becoming known
that makes any statement made in such Registration Statement or related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires the making of any
changes in such Registration Statement, Prospectus or documents so that, in the
case of the Registration Statement, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, and that in the case
of the Prospectus, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided, however, that such notification need not
specifically identify such event if notification of the occurrence thereof would
in the Company's reasonable judgment, involve the disclosure of confidential
non-public information; and (vi) of the Company's reasonable determination that
a post-effective amendments to the Registration Statement would be appropriate;

                  (d) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, use its reasonable best efforts to
prevent the issuance of any order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of a Prospectus or
suspending the qualification (or exemption from qualification) of any of the
Registrable Securities or the Exchange Securities to be sold by any
Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
order is issued, to use its reasonable best efforts to obtain the withdrawal of
any such order at the earliest possible moment;

                  (e) if a Shelf Registration Statement is filed pursuant to
Section 3 and if requested by the managing underwriters, if any, or the Holders
of a majority in aggregate principal amount of the Registrable Securities being
sold in connection with an underwritten offering, (i) promptly incorporate in a
prospectus supplement or post-effective amendment such information as the
managing underwriters, if any, or such Holders or their respective counsel
reasonably request to be included therein; and (ii) make all required filings of
such prospectus supplement or such post-effective amendment as soon as
reasonably practicable after the Company has received notification of the
matters to be incorporated in such prospectus supplement or post-effective
amendment;

                  (f) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, furnish to each selling Holder of
Registrable Securities and to each such Participating Broker-Dealer who so
requests and upon request to their respective counsel and each managing
underwriter, if any, without charge, one conformed copy of the Registration
Statement or Statements and each post-effective amendment thereto, including
financial statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference and all exhibits;

                  (g) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, deliver to each selling Holder of
Registrable Securities, or each such Participating Broker-Dealer, as the case
may be, their counsel, and the underwriters, if any, without charge, as many
copies of the Prospectus or Prospectuses (including each form of preliminary
prospectus) and each amendment or supplement thereto and any documents
incorporated by reference therein as such Persons may reasonably request; and,
sub-

                                      -11-


ject to the last paragraph of this Section 5, the Company hereby consents to
the use of such Prospectus and each amendment or supplement thereto by each of
the selling holders of Registrable Securities or each such Participating
Broker-Dealer, as the case may be, and the underwriters or agents, if any, and
dealers (if any), in connection with the offering and sale of the Registrable
Securities covered by or the sale by Participating Broker-Dealers of the
Exchange Securities pursuant to such Prospectus and any amendment or supplement
thereto provided such use complies with all applicable laws and regulations;

                  (h) prior to any public offering of Registrable Securities or
any delivery of a Prospectus contained in the Exchange Offer Registration
Statement by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, use its reasonable best efforts to
register or qualify, and to cooperate with the selling Holders of Registrable
Securities or each such Participating Broker-Dealer, as the case may be, the
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any selling Holder, Participating Broker-Dealer, or the managing underwriters
reasonably request in writing; provided, however, that where Exchange Securities
held by Participating Broker-Dealers or Registrable Securities are offered other
than through an underwritten offering, the Company shall cause its counsel to
(i) perform Blue Sky investigations and file registrations and qualifications
required to be filed pursuant to this Section 5(h); (ii) use its reasonable best
efforts to keep each such registration or qualification (or exemption therefrom)
effective during the period such Registration Statement is required to be kept
effective; and (iii) do any and all other acts or things necessary or advisable
to enable the disposition in such jurisdictions of the Exchange Securities held
by Participating Broker-Dealers or the Registrable Securities covered by the
applicable Registration Statement; provided, further, that the Company shall not
in any case be required to (A) qualify generally to do business in any
jurisdiction where it is not then so qualified, (B) take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject, (C) subject itself to taxation in excess of a nominal
dollar amount in any such jurisdiction;

                  (i) if a Shelf Registration Statement is filed pursuant to
Section 3, cooperate with the selling Holders of Registrable Securities and the
managing underwriters, if any, to facilitate the timely preparation and delivery
of certificates representing Registrable Securities to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company; and enable such
Registrable Securities to be in such denominations and registered in such names
as the managing underwriter or underwriters, if any, or Holders may reasonably
request;

                  (j) use its reasonable best efforts to cause the Registrable
Securities covered by the Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to enable the seller or sellers thereof or the underwriters, if any, to
consummate the disposition of such Registrable Securities, except as may be
required solely as a consequence of the nature of such selling Holder's
business, in which case the Company will cooperate in all reasonable respects
with the filing of such Registration Statement and the granting of such
approvals; provided, further, that the Company shall not in any case be required
to (A) qualify generally to do business in any jurisdiction where it is not then
so qualified, (B) take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject, (C) subject
itself to taxation in excess of a nominal dollar amount in any such
jurisdiction;

                  (k) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, upon the occurrence of any event
contemplated by paragraph 5(c)(v) or 5(c)(vi) above, as
<PAGE>   13
                                      -12-

promptly as practicable prepare and (subject to Section 5(a) above) file with
the Commission, solely at the expense of the Company, a supplement or
post-effective amendment to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities being sold thereunder
or to the purchasers of the Exchange Securities to whom such Prospectus will be
delivered by a Participating Broker-Dealer, any such Prospectus will not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. The Company
agrees to notify the Holders to suspend use of any such Prospectus as promptly
as practicable after the occurrence of such event, and the Holders agree, upon
receipt of such notice, to suspend use of any such Prospectus until the Company
has amended or supplemented such Prospectus to correct such misstatement or
omission;

                  (l) use its reasonable best efforts to cause the Registrable
Securities covered by a Registration Statement or the Exchange Securities, as
the case may be, to be rated with the appropriate rating agencies, if so
requested by the Holders of a majority in aggregate principal amount of

Securities, as the case may be, or the managing underwriters, if any;

                  (m) prior to the effective date of the first Registration
Statement relating to the Registrable Securities, (i) provide the Trustee with
certificates for the Registrable Securities in a form eligible for deposit with
The Depository Trust Company; and (ii) provide a CUSIP number for the
Registrable Securities;

                  (n) in connection with an underwritten offering of Registrable
Securities pursuant to a Shelf Registration Statement, enter into an
underwriting agreement as is customary in underwritten offerings, provided such
agreement is reasonably acceptable to the Company and provided that the
underwriters are reasonably acceptable to the Company, and take all such other
actions as are reasonably requested by the managing underwriters in order to
expedite or facilitate the registration or the disposition of such Registrable
Securities, and in such connection if reasonably requested, (i) make such
representations and warranties to the underwriters, with respect to the business
of the Company and its subsidiaries and the Registration Statement, Prospectus
and documents, if any, incorporated or deemed to be incorporated by reference
therein, in each case, as are customarily made by issuers to underwriters in
underwritten offerings, and confirm the same if and when reasonably requested;
(ii) use its reasonable best efforts to obtain opinions of counsel to the
Company and updates thereof in form and substance reasonably satisfactory to the
managing underwriters, addressed to the underwriters covering the matters
customarily covered in opinions requested in underwritten offerings and such
other matters as may be reasonably requested by underwriters; (iii) use its
reasonable best efforts to obtain "cold comfort" letters and updates thereof in

or of any business acquired by the Company or any of its subsidiaries for which
financial statements and financial data are, or are required to be, included in
the Registration Statement), addressed to each of the underwriters, such letters
to be in customary form and covering matters of the type customarily covered in
"cold comfort" letters in connection with underwritten offerings and such other
matters as reasonably requested by underwriters; and (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and
procedures comparable to those set forth in Section 7 hereof (or such other
provisions and procedures reasonably acceptable to the Company and the Holders
of a majority in aggregate principal amount of Registrable Securities covered by
such Registration Statement and the managing underwriters or agents) with
respect to all parties to be indemnified pursuant to said section, all of which
shall be done at each closing under such underwriting agreement, or as and to
the extent required thereunder;
<PAGE>   14
                                      -13-

                  (o) if (1) a Shelf Registration Statement is filed pursuant to
Section 3, or (2) a Prospectus contained in an Exchange Offer Registration
Statement filed pursuant to Section 2 is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Securities during the Applicable Period, subject to the prior receipt by the
Company of undertakings to use commercially reasonable best efforts to preserve
the confidentiality of any information disclosed by the Company pursuant hereto
in form and substance reasonably satisfactory to the Company, make available for
inspection by any selling Holder of such Registrable Securities being sold, or
each such Participating Broker-Dealer, as the case may be, any underwriter
participating in any such disposition of Registrable Securities, if any, and any
attorney, accountant or other agent retained by any such selling holder or each
such Participating Broker-Dealer, as the case may be, or underwriter
(collectively, the "Inspectors"), at the offices where normally kept, during
reasonable business hours, all relevant financial and other records, pertinent
corporate documents and properties of the Company and its subsidiaries
(collectively, the "Records") as shall be necessary to enable them to exercise
any applicable due diligence responsibilities, and cause the officers, directors
and employees of the Company and its subsidiaries to supply all information in
each case requested by any such Inspector in connection with such Registration
Statement; however, records which the Company determines, in good faith, to be
confidential and any Records which the Company notifies the Inspectors are
confidential shall not be disclosed by the Inspectors unless (i) the disclosure
of such Records is necessary to avoid or correct a misstatement or omission in
such Registration Statement; (ii) the release of such Records is ordered
pursuant to a subpoena or other order from a court of competent jurisdiction;
(iii) the information in such Records has been made generally available to the
public; or (iv) release thereof is necessary or advisable in connection with any
action, suit or proceeding involving any Holder or other Inspector;

                  (p) provide for an indenture trustee for the Registrable
Securities or the Exchange Securities, as the case may be, and cause the
Indenture or the trust indenture provided for in Section 2(a), as the case may
be, to be qualified under the TIA not later than the effective date of the
Exchange Offer or the first Registration Statement relating to the Registrable
Securities; and in connection therewith, cooperate with the trustee under any
such indenture and the holders of the Registrable Securities, to effect such
changes to such indenture as may be required for such indenture to be so
qualified in accordance with the terms of the TIA; and execute, and use its
reasonable best efforts to cause such trustee to execute, all documents as may
be required to effect such changes, and all other forms and documents required
to be filed with the Commission to enable such indenture to be so qualified in a
timely manner;

                  (q) comply with all applicable rules and regulations of the
Commission to the extent and so long as they are applicable to the Exchange
Offer Registration Statement or the Shelf Registration Statement and make
generally available to their Securityholders earning statements satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or
any similar rule promulgated under the Securities Act) no later than 45 days
after the end of any 12-month period (or 90 days after the end of any 12-month
period if such period is a fiscal year) (i) commencing at the end of any fiscal
quarter in which Registrable Securities are sold to underwriters in a firm
commitment or best efforts underwritten offering; and (ii) if not sold to
underwriters in such an offering, commencing on the first day of the first
fiscal quarter of the Company after the effective date of a Registration
Statement, which statements shall cover said 12-month periods;

                  (r) upon consummation of an Exchange Offer or a Private
Exchange, obtain an opinion of counsel to the Company in customary form,
relating to the Exchange Securities or the Private Exchange Securities, as
the case may be, addressed to the Trustee for the benefit of all Holders of
Registrable Securities participating in the Exchange Offer or the Private
Exchange, as the case may be, and which includes an opinion that (i) the Company
has duly authorized, executed and delivered the Exchange Securities and Private
Exchange Securities and the related indenture; and (ii) each of the Exchange
Securities or the Private Exchange Securities, as
<PAGE>   15
                                      -14-


the case may be, and related indenture constitute valid and legally binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms (with customary exceptions);

                  (s) if an Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Securities by Holders to the
Company (or to such other Person as directed by the Company) in exchange for the
Exchange Securities or the Private Exchange Securities, as the case may be,
mark, or caused to be marked, on such Registrable Securities that such
Registrable Securities are being canceled in exchange for the Exchange
Securities or the Private Exchange Securities, as the case may be; in no event
shall such Registrable Securities be marked as paid or otherwise satisfied;

                  (t) cooperate with each seller of Registrable Securities
covered by any Registration Statement and each underwriter, if any,
participating in the disposition of such Registrable Securities and their
respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. (the "NASD"); and

                  (u) use its reasonable best efforts to take all other steps
necessary to effect the registration of the Registrable Securities covered by a
Registration Statement contemplated hereby.

                  The Company may require each seller of Registrable Securities
or Participating Broker-Dealer as to which any registration is being effected to
furnish to the Company such information regarding such seller or Participating
Broker-Dealer and the distribution of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
as the Company may, from time to time, reasonably request. The Company may
exclude from such registration the Registrable Securities of any seller or
Participating Broker-Dealer who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

                  Each Holder of Registrable Securities and each Participating
Broker-Dealer agrees by acquisition of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi), such
Holder will forthwith discontinue disposition of such Registrable Securities
covered by such Registration Statement or Prospectus or Exchange Securities to
be sold by such Participating Broker-Dealer, as the case may be, until such
holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto.

6.    REGISTRATION EXPENSES

                  (a) All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by the Company
whether or not the Exchange Offer Registration Statement or a Shelf Registration
Statement is filed or becomes effective, including, without limitation, (i) all
registration and filing fees (including, without limitation, (A) fees with
respect to filings required to be made with the NASD in connection with an

for deposit with The Depository Trust Company and of printing prospectuses if
the printing of prospectuses is requested by the managing underwriters, if any,
or, in respect of Registrable Securities or Exchange Securities to be sold by
any Participating Broker-Dealer during the Applicable Period, by the Holders of
a majority in aggregate principal amount of the Registrable Securities included
in any Registration Statement or of such Exchange Securities, as the case may
be); (iii) messenger, telephone and delivery expenses incurred by the Company;
(iv) fees and disbursements of counsel for the Company and all documentation

Securities on any Securities exchange; and (xiii) the expenses relating to
printing, word processing and distributing all Registration Statements,

herein to the contrary notwithstanding, the Company shall not have any
obligation whatsoever in respect of any fees or expenses of counsel to any
underwriters, underwriters' discounts or commissions, brokerage commissions,
dealers' selling concessions, transfer taxes or any other selling expenses
(other than those expressly enumerated in clauses (i) through (xiii) above)
incurred in connection with the underwriting, offering or sale of Registrable
Securities or Exchange Securities by or on behalf of any Person.

                  (b) In connection with any Shelf Registration Statement
hereunder, the Company shall reimburse the Holders of the Registrable Securities
being registered in such registration for the reasonable fees and disbursements
of not more than one counsel (in addition to appropriate local counsel) chosen
by the Holders of a majority in aggregate principal amount of the Registrable
Securities to be included in such Registration Statement and other reasonable
out-of-pocket expenses of the Holders of Registrable Securities incurred in
connection with the registration of the Registrable Securities.

7.    INDEMNIFICATION

                  The Company agrees to indemnify and hold harmless each Holder
of Registrable Securities and each Participating Broker-Dealer selling Exchange
Securities during the Applicable Period, the officers and directors of each such
person, and each person, if any, who controls any such person within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act
(each, a "Participant"), from and against any and all losses, claims, damages
and liabilities (including, without limitation, the reasonable legal fees and
other expenses incurred in connection with any suit, action or proceeding or any
claim asserted) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto) or any preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any untrue statement
or omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to such Participant furnished to the
Company in writing by such Participant (or, if such Participant is not a Holder
or a Participating Broker-Dealer, furnished in writing by the Holder or
Participating Broker-Dealer in respect of which such person is a Participant
<PAGE>   17
                                      -16-

relating to such Participant) expressly for use therein; provided, however, that
the foregoing indemnity with respect to any preliminary prospectus shall not
inure to the benefit of any Participant (or, if such Participant is not a Holder
or a Participating Broker-Dealer, furnished in writing by the Holder or
Participating Broker-Dealer in respect of which such person is a Participant
relating to such Participant) from whom the person asserting any such losses,
claims, damages or liabilities purchased Registrable Securities to the extent
that such untrue statement or omission or alleged untrue statement or omission
made in such preliminary prospectus is eliminated or remedied in the related
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) and a copy of the related Prospectus (as so
amended or supplemented) shall not have been furnished to such person at or
prior to the sale of such Registrable Securities or Exchange Securities, as the
case may be, to such person .

                  Each Participant will be required to agree, severally and not
jointly, to indemnify and hold harmless each of the Company, its directors, its
officers who sign the Registration Statement and each person who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act to the same extent as the foregoing indemnity from the Company
to each Participant, but only with reference to information relating to such
Participant furnished to the Company in writing by such Participant expressly
for use in any Registration Statement or Prospectus, any amendment or supplement
thereto, or any preliminary prospectus. The liability of any Participant under
this paragraph shall in no event exceed the proceeds received by such
Participant from sales of Registrable Securities giving rise to such
obligations.

                  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding; and shall pay the
reasonable fees and expenses incurred by such counsel related to such
proceeding, provided, however, that the failure to so notify the Indemnifying
Person shall not relieve it of any obligation or liability which it may have
hereunder or otherwise (unless and only to the extent that such failure actually
prejudices the Indemnifying Person). In any such proceeding, any Indemnified
Person shall have the right to retain its own counsel, but, other than in
circumstances involving a conflict among Indemnified Persons, the fees and
expenses of such counsel shall be at the expense of such Indemnified Person
unless (i) the Indemnifying Person and the Indemnified Person shall have agreed
to the contrary; (ii) the Indemnifying Person has failed within a reasonable
time to retain counsel reasonably satisfactory to the Indemnified Person; or
(iii) the named parties in any such proceeding (including any impleaded parties)
include both the Indemnifying Person and the Indemnified Person and
representation of both parties by the same counsel would be inappropriate due to
an actual or potential conflict of interest. It is understood that, other than
in circumstances involving a conflict among Indemnified Persons, the
Indemnifying Person shall not, in connection with any proceeding or related
proceeding in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for the Participants shall be designated in
writing by Participants who sold a majority in interest of Registrable
Securities sold by all such Participants and any such separate firm for the
Company, its directors, its officers and such control persons of the Company
shall be designated in writing by the Company. The Indemnifying Person shall not
be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified
Person from and against any loss or liability by reason of such settlement or
judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified
Person shall have requested an Indemnifying Person to reimburse the Indemnified
Person for reasonable fees and expenses
<PAGE>   18
                                      -17-

incurred by counsel as contemplated by the third sentence of this paragraph, the
Indemnifying Person agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 60 days after receipt by such Indemnifying Person of the
aforesaid request and (ii) such Indemnifying Person shall not have reimbursed
the Indemnified Person in accordance with such request prior to the date of such
settlement. No Indemnifying Person shall, without the prior written consent of
the Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party, unless such settlement includes an unconditional written release of such
Indemnified Person in form and substance satisfactory to the Indemnified Persons
from all liability on claims that are the subject matter of such proceeding.

                  If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
(i) the relative benefits received by the Indemnifying Person or Persons on the
one hand and the Indemnified Person or Persons on the other from the initial
offering of the Notes or (ii) if the allocation provided by the foregoing clause
(i) is not permitted by applicable law, not only such relative benefits but also
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Participants on the other shall be deemed to be
in the same proportion as the total proceeds from the initial offering (net of
discounts and commissions but before deducting expenses) of the Notes received
by the Company bears to the total proceeds received by such Participant from the
sale of Registrable Securities. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, on the one hand,
or such Participant or such other Indemnified Person, as the case may be, on the
other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances.

                  The parties shall agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Participants were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any reasonable legal or other expenses actually incurred by such
Indemnified Person in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Securities
exceeds the amount of any damages that such Participant has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                  The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability which the Indemnifying Persons
may otherwise have to the Indemnified Persons referred to above.

8.    RULE 144 AND RULE 144A

                  The Company covenants that it will file the reports required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations adopted by the Commission thereunder in a timely manner and, if
at any time the Company is not required to file such reports, it will, upon the
request of any Holder of Registrable Securities, make publicly available other
information so long as necessary to permit sales pursuant to Rule 144 and Rule
144A under the Securities Act. The Company further covenants that it will take
such further action as any Holder of Registrable Securities may reasonably
request, to the extent required from time to time to enable such Holder to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 and Rule 144A under the
Securities Act.

9.    UNDERWRITTEN REGISTRATIONS

                  If any of the Registrable Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will manage
the offering will be selected by the Holders of a majority in aggregate
principal amount of such Registrable Securities included in such offering and
reasonably acceptable to the Company.

                  No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements (however the terms applicable to each Holder shall be identical in
all respects) and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements applicable to all Holders.

10.    MISCELLANEOUS

                  (a) Remedies. In the event of a breach by the Company of any
of its obligations under this Agreement, each Holder of Registrable Securities,
in addition to being entitled to exercise all rights provided herein, in the
Indenture or, in the case of the Initial Purchasers, in the Purchase Agreement
or granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Agreement. The Company agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by it of any of the provisions of this Agreement and hereby further
agrees that, in the event of any action for specific performance in respect of
such breach, it shall waive the defense that a remedy at law would be adequate.

                  (b) No Inconsistent Agreements. The Company has not, as of the
date hereof, entered into and shall not, after the date of this Agreement, enter
into any agreement with respect to any of its Securities that is inconsistent
with the rights granted to the Holders of Registrable Securities in this
Agreement or otherwise conflicts with the provisions hereof. The Company has not
entered into and will not enter into any agreement with respect to any of its
securities which will grant to any Person "piggy-back" rights with respect to a
Registration Statement.

                  (c) Adjustments Affecting Registrable Securities. The Company
shall not, directly or indirectly, take any action with respect to the
Registrable Securities as a class that would adversely affect the ability of the
Holders of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement.
<PAGE>   20
                                      -19-



                  (e) Amendments and Waivers. Except as provided in paragraph
(d) above, the provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, otherwise than by an instrument executed and delivered by (A)
the Holders of not less than a majority in aggregate principal amount of the
then outstanding Registrable Securities and (B) in circumstances that would
adversely affect the Participating Broker-Dealers, the Participating
Broker-Dealers holding not less than a majority in aggregate principal amount of
the Exchange Securities held by all Participating Broker-Dealers; provided,
however, that Section 7 and this Section 10(e) may not be amended, modified or
supplemented except by an instrument executed and delivered by each Holder and
each Participating Broker-Dealer (including any person who was a Holder or
Participating Broker-Dealer of Registrable Securities or Exchange Securities, as

      Escrow Account at any time shall be invested by Escrow Agent in Cash
      Equivalents in accordance with Company's written instructions from time to
      time to Escrow Agent; provided, however, that (1) Company shall only

      if required, and shall be executed by an Officer of Company. Escrow Agent

      Section 2(d)(i), Escrow Agent shall have no obligation to invest funds
      held in the Escrow Account.

                                       -6-


            (ii) Security Interest in Investments. No investment of funds in the
      Escrow Account shall be made unless the Company has certified to Escrow
      Agent and Trustee that, upon such investment, Escrow Agent will have a
      first priority perfected security interest in the applicable investment.
      If a certificate as to a class of investments has been provided to Escrow
      Agent, a certificate need not be issued with respect to individual
      investments in securities in that class if the certificate applicable to
      the class remains accurate with respect to such individual investments,
      which continued accuracy Escrow Agent may conclusively assume. On the date
      of this Agreement, and on each anniversary thereof (upon receipt of
      written notice from Escrow Agent), until the date upon which the balance
      of the Available Funds shall have been reduced to zero, each of Trustee
      and Escrow Agent shall receive an Opinion of Counsel to Company, dated
      each such date as applicable, which opinion shall meet the requirements of
      Section 314(b) of the United States Trust Indenture Act of 1939, as
      amended (the "TIA") and shall comply with Section 11.02 of the Indenture.

            (iii) Interest and Dividends. All interest earned and dividends paid
      on the Pledged Securities or any funds invested in Cash Equivalents shall
      be deposited in the Escrow Account as additional Collateral for the
      exclusive benefit of the Beneficiaries and, if not required to be
      disbursed in accordance with the terms hereof, subject to subsections
      6(b)(iii), 6(e) and 6(f), shall be reinvested in accordance with the terms
      hereof at Company's written instruction unless a Default or Event of
      Default has occurred or Trustee has notified Escrow Agent that it should
      only take direction from Trustee or should no longer take direction from
      Company.

            (iv) Limitation on Escrow Agent's Responsibilities. Escrow Agent's
      sole responsibilities under this Section 2 shall be (A) to retain
      possession of certificated Cash Equivalents (except, however, that Escrow
      Agent may surrender possession to the issuer of any such Cash Equivalent
      for the purposes of effecting assignment, crediting interest, or
      reinvesting such security or reducing such security to cash) and to be the
      registered or designated owner of the Pledged Securities and any Cash
      Equivalents which are not certificated, (B) to follow Company's written
      instructions given in accordance with Section 2(d)(i), (C) to invest and
      reinvest funds pursuant to this Section 2(d) and (D) to use reasonable
      efforts to
<PAGE>   7

                                       -7-


      reduce to cash such Cash Equivalents as may be required to fund any
      disbursement or payment in accordance with Section 3. In connection with
      clause (A) above, Escrow Agent will maintain continuous possession in the
      jurisdiction of its principal place of business of certificated Cash
      Equivalents and cash included in the Collateral and will cause the Pledged
      Securities and any uncertificated Cash Equivalents to be registered in the
      book-entry system of, and transferred to an account of Escrow Agent or a
      sub-agent of Escrow Agent at, any Federal Reserve Bank. Except as provided
      in Section 6, Escrow Agent shall have no other responsibilities with
      respect to perfecting or maintaining the perfection of the security
      interest in the Collateral and shall not be required to file any
      instrument, document or notice in any public office at any time or times.
      In connection with clause (D) above and subject to the following sentence,
      Escrow Agent shall not be required to reduce to cash any Cash Equivalents
      to fund any disbursement or payment in accordance with Section 3 in the
      absence of written instructions signed by an Officer of Company specifying
      the particular investment to liquidate. If no such written instructions
      are received, Escrow Agent may liquidate those Cash Equivalents having the
      lowest interest rate per annum or if none such exist, those having the
      nearest maturity.

            (e) Substitution of Escrow Agent. Escrow Agent may resign by giving
no less than 15 Business Days prior written notice to Company and Trustee. Such
resignation shall take effect upon the later to occur of (i) delivery of all
funds, the Pledged Securities and any Cash Equivalents maintained by Escrow
Agent hereunder and copies of all books, records, plans and other documents in
Escrow Agent's possession relating to such funds, the Pledged Securities or any
Cash Equivalents or this Agreement to a successor escrow agent mutually approved
by Company and Trustee (which approvals shall not be unreasonably withheld or
delayed) and the taking of such other steps as may be necessary to give the
successor escrow agent a first priority security interest in the Pledged
Securities and (ii) Company, Trustee and such successor escrow agent entering
into this Agreement or any written successor agreement no less favorable to the
interests of the holders of the Securities and Trustee than this Agreement; and
Escrow Agent shall thereupon be discharged of all obligations under this
Agreement and shall have no further duties, obligations or responsibilities in
connection herewith, except as set forth in Section 4. If a successor escrow
agent has not been appointed or has not accepted
<PAGE>   8

                                       -8-


such appointment within 20 Business Days after notice of resignation is given to
Company, Escrow Agent may apply to a court of competent jurisdiction for the
appointment of a successor escrow agent.

            (f) Escrow Account Statement. At least 30 days prior to each
Interest Payment Date, Escrow Agent shall deliver to Company and Trustee a
statement setting forth with reasonable particularity the balance of funds then
in the Escrow Account and the manner in which such funds are invested ("Escrow
Account Statement"). The parties hereto irrevocably instruct Escrow Agent that
on the first date upon which the balance in the Escrow Account (including the
holdings of all Cash Equivalents) is reduced to zero, Escrow Agent shall deliver
to Company and to Trustee a notice that the balance in the Escrow Account has
been reduced to zero.

            3. Disbursements

            (a) Payment Notice and Disbursement Request; Disbursements. Up to
five business days prior to an Interest Payment Date, Company may submit to
Escrow Agent, with a copy to Trustee a completed Payment Notice and Disbursement
Request substantially in the form of Exhibit A hereto.

            Escrow Agent's disbursement pursuant to any Payment Notice and
Disbursement Request shall be subject to the satisfaction of the applicable
conditions set forth in Section 3 (b). Provided such Payment Notice and
Disbursement Request is not rejected by it, Escrow Agent, as soon as reasonably
practicable on the Interest Payment Date, but in no event later than 12:00 Noon
(New York City time) on the Interest Payment Date, shall disburse the funds
requested in such Payment Notice and Disbursement Request by wire or book-entry
transfer of immediately available funds to the account of Trustee for the
benefit of the Beneficiaries. Escrow Agent shall notify Trustee as soon as
reasonably possible (but not later than two (2) Business Days from the date of
receipt of the Payment Notice and Disbursement Request) if any Payment Notice
and Disbursement Request is rejected and the reason(s) therefor. In the event
such rejection is based upon nonsatisfaction of the condition in Section 3 (b)
(I), Company shall thereupon resubmit the Payment Notice and Disbursement
Request with appropriate changes.

            (b) Conditions Precedent to Disbursement. Escrow Agent's payment of
any disbursement shall be made only if: (I) Company shall have submitted, in
accordance with the provisions
<PAGE>   9

                                       -9-


of Section 3(a), a completed Payment Notice and Disbursement Request to Escrow
Agent substantially in the form of Exhibit A with blanks appropriately filled
in, and (II) Escrow Agent shall not have received any notice from Trustee that
as a result of an Event of Default the indebtedness represented by the
Securities has been accelerated and has become due and payable (in which event
Escrow Agent shall apply all Available Funds as required by Section 6(b)(iii)).

            (c) Company Payments. If Company makes any interest payment or
portion of an interest payment on the Securities from a source of funds other
than the Escrow Account ("Company Funds"), Company may, after payment in full of
such interest payment, direct Escrow Agent to release to Company or at the
direction of Company an amount of funds from the Escrow Account less than or
equal to the amount of Company Funds so expended. Upon receipt of a request from
Company (including the certificate described in the following sentence), Escrow
Agent will pay over to Company the requested amount. Concurrently with any
release of funds to Company pursuant to this Section 3(c), Company will deliver
to Escrow Agent a certificate signed by an authorized signatory of Company
stating that such release has been duly authorized by all necessary corporate
action, and does not contravene, or constitute a default under, any provision of
applicable law or regulation or of the Articles of Association of Company or of
any agreement, judgment, injunction, order, decree or other instrument binding
upon Company or result in the creation or imposition of any Lien on any assets
of Company.

            (d) If at any time the principal of and interest on the Collateral
exceeds 100% of the amount sufficient, in the written opinion of a nationally
recognized firm of independent accountants selected by Company and delivered to
Escrow Agent and Trustee, to provide for payment in full of the interest on
outstanding Securities on each Interest Payment Date beginning on and including
February 15, 1998 and through and including the Interest Payment Date on August
15, 1999 (or, in the event one or more interest payments have been made thereon,
an amount sufficient to provide for the payment in full of any and all interest
payments on the Securities then remaining, up to and including the fourth
scheduled interest payment), Company may direct Escrow Agent and Trustee to
release any such overfunded amount to Company or to such other party as Company
may direct. Upon receipt of written instructions executed by Company in the form
of an Officers' Certificate, Trustee shall pay, or shall cause the payment, over
to Company or Company's designee, as
<PAGE>   10

                                      -10-


the case may be, any such overfunded amount.

            4. Escrow Agent.

            (a) Limitation of Escrow Agent's Liability; Responsibilities of
Escrow Agent. Escrow Agent's responsibility and liability under this Agreement
shall be limited as follows: (i) Escrow Agent does not represent, warrant or
guaranty to the holders of the Securities from time to time the performance of
Company; (ii) Escrow Agent shall have no responsibility to Company or the
holders of the Securities or Trustee from time to time as a consequence of
performance or non-performance by Escrow Agent hereunder, except for any bad
faith, gross negligence or willful misconduct of Escrow Agent; (iii) Company
shall remain solely responsible for all aspects of Company's business and
conduct; and (iv) Escrow Agent is not obligated to supervise, inspect or inform
Company or any third party of any matter referred to above. In no event shall
Escrow Agent be liable (i) for acting in accordance with or relying upon any
instruction, notice, demand, certificate or document from Company or any entity
acting on behalf of Company, (ii) for any consequential, punitive or special
damages, (iii) for the acts or omissions of its nominees, correspondents,
designees, subagents or subcustodians or (iv) for an amount in excess of the
value of the Escrow Account, valued as of the date of deposit.

            No implied covenants or obligations shall be inferred from this
Agreement against Escrow Agent, nor shall Escrow Agent be bound by the
provisions of any agreement beyond the specific terms hereof. Specifically and
without limiting the foregoing, Escrow Agent shall in no event have any
liability in connection with its investment, reinvestment or liquidation, in
good faith and in accordance with the terms hereof, of any funds, the Pledged
Securities or Cash Equivalents held by it hereunder, including without
limitation any liability for any delay not resulting from gross negligence or
willful misconduct in such investment, reinvestment or liquidation, or for any
loss of principal or income incident to any such delay.

            Escrow Agent shall be entitled to rely upon any judicial or
administrative order or judgment, upon any opinion of counsel or upon any
certification, instruction, notice, or other writing delivered to it by Company
or Trustee in compliance with the provisions of this Agreement without being
required to determine the authenticity or the correctness of any fact stated
therein or the propriety or validity of service thereof. Escrow Agent may act in
reliance upon any instrument
<PAGE>   11

                                      -11-


comporting with the provisions of this Agreement or signature believed by it to
be genuine and may assume that any person purporting to give notice or receipt
or advice or make any statement or execute any document in connection with the
provisions hereof has been duly authorized to do so.

            At any time Escrow Agent may request in writing an instruction in
writing from Company (other than any disbursement pursuant to Section
6(b)(iii)), and may at its own option include in such request the course of
action it proposes to take and the date on which it proposes to act, regarding
any matter arising in connection with its duties and obligations hereunder;
provided, however, that Escrow Agent shall state in such request that it
believes in good faith that such proposed course of action is consistent with
another identified provision of this Agreement. Escrow Agent shall not be liable
to Company for acting without Company's consent in accordance with such a
proposal on or after the date specified therein if (i) the specified date is at
least four Business Days after Company receives Escrow Agent's request for
instructions and its proposed course of action, and (ii) prior to so acting,
Escrow Agent has not received the written instructions requested from Company.

            At the expense of Company, Escrow Agent may act pursuant to the
advice of counsel chosen by it with respect to any matter relating to this
Agreement and (subject to clause (ii) of the first paragraph of this Section
4(a)) shall not be liable for any action taken or omitted in accordance with
such advice.

            Escrow Agent shall not be called upon to advise any party as to
selling or retaining, or taking or refraining from taking any action with
respect to, any securities or other property deposited hereunder.

            In the event of any ambiguity in the provisions of this Agreement
with respect to any funds, securities or property deposited hereunder, Escrow
Agent shall be entitled to refuse to comply with any and all claims, demands or
instructions with respect to such funds, securities or property, and Escrow
Agent shall not be or become liable for its failure or refusal to comply with
conflicting claims, demands or instructions. Escrow Agent shall be entitled to
refuse to act until either any conflicting or adverse claims or demands shall
have been finally determined by a court of competent jurisdiction or settled by
agreement between the conflicting claimants as evidenced in a writing,
satisfactory to Escrow Agent, or Escrow
<PAGE>   12

                                      -12-


Agent shall have received security or an indemnity satisfactory to Escrow Agent
sufficient to save Escrow Agent harmless from and against any and all loss,
liability or expense which Escrow Agent may incur by reason of its acting.
Escrow Agent may in addition elect in its sole option to commence an
interpleader action or seek other judicial relief or orders as Escrow Agent may
deem necessary. The costs and expenses (including reasonable attorney's fees and
expenses) incurred in connection with such proceedings shall be paid by, and
shall be deemed an obligation of Company.

            No provision of this Agreement shall require Escrow Agent to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder.

            Escrow Agent shall not incur any liability for not performing any
act or fulfilling any duty, obligation or responsibility hereunder by reason of
any occurrence beyond the control of Escrow Agent (including but not limited to
any act or provision of any present or future law or regulation or governmental
authority, any act of God or war, or the unavailability of the Federal Reserve
Bank wire or telex or other wire or communication facility).

            5. Indemnity. Company shall indemnify, hold harmless and defend
Trustee and Escrow Agent and their respective directors, officers, agents,
employees and controlling persons, from and against any and all claims, actions,
obligations, liabilities and expenses, including reasonable defense costs,
reasonable investigative fees and costs, reasonable legal fees, and claims for
damages, arising from Trustee's or Escrow Agent's performance or
non-performance, or in connection with Escrow Agent's acceptance of appointment
as Escrow Agent under this Agreement, except to the extent that such liability,
expense or claim is solely and directly attributable to the bad faith, gross
negligence or willful misconduct of any of the foregoing persons. The provisions
of this Section 5 shall survive any termination, satisfaction or discharge of
this Agreement as well as the resignation or removal of Escrow Agent.

            6. Grant of Security Interest; Instructions to Escrow Agent.

            (a) Company hereby irrevocably grants a first priority security
interest in and lien on, and pledges, assigns, transfers and sets over to Escrow
Agent for the ratable benefit of the Beneficiaries, all of Company's right,
title and inter-
<PAGE>   13

                                      -13-


est in the Escrow Account, and all property now or hereafter placed or deposited
in, or delivered to Escrow Agent for placement or deposit in, the Escrow
Account, including, without limitation, the Pledged Securities, all funds held
therein, all Cash Equivalents held by (or otherwise maintained in the name of)
Escrow Agent pursuant to Section 2, and all proceeds thereof as well as all
rights of Company under this Agreement (collectively, the "Collateral"), in
order to secure all obligations and indebtedness of Company under the Indenture,
the Securities and any other obligation, now or hereafter arising, of every kind
and nature, owed by Company under the Indenture or the Securities to the holders
of the Securities or to Trustee or any predecessor Trustee (the "Secured
Obligations"). Escrow Agent hereby acknowledges Trustee's security interest and
lien as set forth above. Company shall take all actions necessary on its part to
insure the continuance of a first priority security interest in the Collateral
in favor of Trustee in order to secure all such obligations and indebtedness.

            (b) Company and Trustee hereby irrevocably instruct Escrow Agent to,
and Escrow Agent shall:

            (i)(A) maintain sole dominion and control over the Pledged
Securities, funds and any Cash Equivalents in the Escrow Account for the benefit
of Trustee to the extent specifically required herein, (B) maintain, or cause
its agent within the jurisdiction of its principal place of business to
maintain, possession of all certificated Cash Equivalents purchased hereunder
that are physically possessed by Escrow Agent in order for Trustee to enjoy a
continuous perfected first priority security interest therein under the law of
the State of New York (Company hereby agreeing that in the event any
certificated Cash Equivalents are in the possession of Company or a third party,
Company shall use its best efforts to deliver all such certificates to Escrow
Agent), (C) take all steps specified by Company pursuant to paragraph (a) of
this Section 6 to cause Escrow Agent to enjoy a continuous perfected first
priority security interest under any applicable Federal and State of New York
law in all Cash Equivalents purchased hereunder that are not certificated and
(D) maintain the Collateral free and clear of all liens, security interests,
safekeeping or other charges, demands and claims against Escrow Agent of any
nature now or hereafter existing in favor of anyone other than Trustee;

            (ii) promptly notify Trustee if Escrow Agent receives written notice
that any Person other than Escrow Agent has a lien or security interest upon any
portion of the Collateral;
<PAGE>   14

                                      -14-


and

            (iii) in addition to disbursing amounts held in escrow pursuant to
any Payment Notice and Disbursement Requests given to it pursuant to Section 3,
upon receipt of written notice from Trustee of the acceleration of the maturity
of the Securities, and direction from Trustee to disburse all Available Funds to
Trustee, as promptly as practicable, disburse all funds held in the Escrow
Account to Trustee and transfer title to all Cash Equivalents held by Escrow
Agent hereunder to Trustee. In addition, upon an Event of Default (as defined in
the Indenture) and for so long as such Event of Default continues, Trustee may,
and Escrow Agent shall on behalf of Trustee when instructed by Trustee, exercise
in respect of the Collateral, in addition to other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party under the UCC or other applicable law, and Trustee may, and Escrow
Agent shall on behalf of Trustee when instructed by Trustee, also upon obtaining
possession of the Collateral as set forth herein, without notice to Company
except as specified below, sell the Collateral or any part thereof in one or
more parcels at public or private sale, at any exchange, broker's board or at
any of Trustee's offices or elsewhere, for cash, on credit or for future
delivery, and upon such other terms as Trustee may deem commercially reasonable.
Company acknowledges and agrees that any such private sale may result in prices
and other terms less favorable to the seller than if such sale were a public
sale. Company agrees that, to the extent notice of sale shall be required by
law, at least ten (10) days' notice to Company of the time and place of any
public sale or the time after which any private sale is to be made shall
constitute reasonable notification. Trustee shall not be obligated to make any
sale regardless of notice of sale having been given. Trustee may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.

            The lien and security interest provided for by this Section 6 shall
automatically terminate and cease as to, and shall not extend or apply to, and
Trustee and Escrow Agent shall have no security interest in, any funds disbursed
by Escrow Agent whether for payment of interest or to Company pursuant to this
Agreement to the extent not inconsistent with the terms hereof. Notwithstanding
any other provision contained in this Agreement, Escrow Agent shall act solely
as Trustee's agent in connection with its duties under this Section 6 or any
other duties herein relating to the Escrow Account or the
<PAGE>   15

                                      -15-


Pledged Securities or any funds or Cash Equivalents held thereunder. Escrow
Agent shall not have any right to receive compensation from Trustee and shall
have no authority to obligate Trustee or to compromise or pledge its security
interest hereunder. Accordingly, Escrow Agent is hereby directed to cooperate
with Trustee in the exercise of its rights in the Collateral provided for
herein.

            (c) Any money and Cash Equivalents collected by Trustee pursuant to
Section 6(b)(iii) shall be applied as provided in Section 4.21 of the Indenture.
Any surplus of such cash or cash proceeds held by Trustee and remaining after
indefeasible payment in full of all the obligations under the Indenture (the
"Escrow Funds") shall be paid over to Company upon Company request or as a court
of competent jurisdiction may direct.

            (d) Company will execute and deliver or cause to be executed and
delivered, or use its best efforts to procure, all stock powers, proxies,
assignments, instruments and other documents, deliver any instruments to Trustee
and take any other actions that are necessary or desirable to perfect, continue
the perfection of, or protect the first priority of Trustee's security interest
in and to the Collateral, to protect the Collateral against the rights, claims,
or interests of third persons or to effect the purposes of this Agreement.
Company also hereby authorizes Trustee to file any financing or continuation
statements with respect to the Collateral without the signature of Company (to
the extent permitted by applicable law). Company will pay all reasonable costs
incurred in connection with any of the foregoing. It being understood that
Trustee has no duty to determine whether to file or record any document or
instrument relating to Collateral.

            (e) Company hereby appoints Trustee as its attorney-in-fact with
full power of substitution to do any act which Company is obligated hereto to
do, and Trustee may, but shall not be obligated to, exercise such rights as
Company might exercise with respect to the Collateral and take any action in
Company's name to protect Trustee's security interest hereunder.

            (f) If at any time Escrow Agent shall receive an "entitlement order"
(within the meaning of Section 8-102(a)(8) of the Revised UCC) issued by Trustee
and relating to the Escrow Account, Escrow Agent shall comply with such
entitlement order without further consent by Company or any other person.

                                     - 16 -


            7. Termination. This Agreement and the security interest in the
Collateral evidenced by this Agreement shall terminate automatically and be of
no further force or effect upon the payment in full in cash of all interest
(including any Additional Interest and any Additional Amounts) due through the
Interest Payment Date occurring on August 15, 1999 and the Collateral shall
promptly be paid over and transferred to the Company; provided, however, that
the obligations of Company under Section 2(c) and Section 5 (and any existing
claims thereunder) shall survive termination of this Agreement and the
resignation of Escrow Agent. At such time, Escrow Agent shall, pursuant to a
certificate of an officer of Company, reassign and redeliver to the Company all
of the Collateral hereunder that has not been sold, disposed of, retained or
applied by Escrow Agent in accordance with the terms of this Agreement and the
Indenture. Such reassignment and delivery shall be without warranty by or
recourse to Escrow Agent in its capacity as such, except as to the absence of
any liens on the Collateral created by or arising through Escrow Agent, and
shall be at the sole expense of Company.

            8. Representations and Warranties.

            Company hereby represents and warrants that:

            (a) The execution, delivery and performance by Company of this
      Agreement are within Company's corporate powers, have been duly authorized
      by all necessary corporate action, and do not contravene, or constitute a
      default under, any provision of applicable law or regulation or of the
      Articles of Association of Company or of any agreement, judgment,
      injunction, order, decree or other instrument binding upon Company or
      result in the creation or imposition of any Lien on any assets of Company,
      except for the security interests granted under this Agreement.

            (b) Company is the beneficial owner of the Collateral, free and
      clear of any Lien or claims of any person or entity (except for the
      security interest, granted under this Agreement). No financing statement
      covering the Collateral is on file in any public office other than the
      financing statements, if any, filed pursuant to this Agreement.

            (c) This Agreement has been duly executed and delivered by Company
      and assuming the due authorization and valid execution and delivery of

      Escrow Agent and Trustee in accordance with its terms, constitutes a valid
      and binding obligation of Company, enforceable against Company in

      (i) the effect of any applicable bankruptcy, insolvency, reorganization,
      moratorium or other similar laws affecting creditors' rights generally,
      (ii) general principles of equity and commercial reasonableness or, (iii)
      the exculpation provisions and rights to indemnification hereunder may be
      limited by U.S. federal and state securities laws and public policy
      considerations and (iv) the waiver of rights and defenses contained in

      instruments, if any, representing the Collateral and the filing of
      financing statements, if any, required by the Uniform Commercial Code (the
      "UCC"), and the transfer and pledge to Escrow Agent of the Collateral and
      the acquisition by Escrow Agent of a security entitlement thereto in
      accordance with Section 6 the pledge of the Collateral pursuant to this
      Agreement creates a valid and perfected first priority security interest
      in and to the Collateral, securing the payment of the Secured Obligations
      for the benefit of the Beneficiaries, enforceable as such against all
      creditors of the Company and any persons purporting to purchase any of the
      Collateral from Company other than as permitted by the Indenture.

            (e) No consent of any other person and no consent, authorization,
      approval, or other action by, and no notice to or filing with, any
      governmental authority or regulatory body is required either (i) for the
      pledge by Company of the Collateral pursuant to this Agreement or for the
      execution, delivery or performance of this Agreement by Company (except
      for any filings necessary to perfect Liens on the Collateral) or (ii) for
      the exercise by Trustee of the rights provided for in this Agreement or
      the remedies in respect of the Collateral pursuant to this Agreement,
      except, in each case, as may be required in connection with such
      disposition by laws affecting the offering and sale of securities.

            (f) No litigation, investigation or proceeding of or before any
      arbitrator or governmental authority is
<PAGE>   18

                                      -18-

      with respect to this Agreement or any of the transactions contemplated
      hereby.

            (g) The pledge of the Collateral pursuant to this Agreement is not
      prohibited by any applicable law or governmental regulation, release,

      Regulations G, T, U and X of the Board of Governors of the Federal Reserve
      System).

            9. Covenants.

therewith other than those imposed under applicable law. Except as provided by
applicable law or by the Indenture, Trustee shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which Trustee accords similar property in similar situations, it being
understood that Trustee shall not have any responsibility for (i) ascertaining
or taking action with respect to calls,
<PAGE>   20

                                      -20-


conversions, exchanges, maturities, tenders or other matters relative to any
Collateral, whether or not Trustee has or is deemed to have knowledge of such
matters or (ii) taking any necessary steps to preserve rights against any
parties with respect to any Collateral; provided, however, that nothing
contained in this Agreement shall relieve Trustee of any responsibilities as a
securities intermediary under applicable law.

            13. Expenses.

            Company will upon demand pay to Trustee the amount of any and all
reasonable expenses, including, without limitation, the reasonable fees,
expenses and disbursements of its counsel, experts and agents retained by
Trustee that Trustee may incur in connection with (i) the administration of this
Agreement, (ii) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, (iii) the exercise or
enforcement of any of the rights of the Beneficiaries hereunder, or (iv) the
failure by Company to perform or observe any of the provisions hereof.

            14. Security Interest Absolute.

            All rights of the Beneficiaries and security interests hereunder,
and all obligations of Company hereunder, shall be absolute and unconditional
irrespective of:

            (a) any lack of validity or enforceability of the Indenture or any
      other agreement or instrument relating thereto;

            (b) any change in the time, manner or place of payment of, or in any
      other term of, all or any of the Secured Obligations, or any other
      amendment or waiver of or any consent to any departure from the Indenture;

            (c) any exchange, surrender, release or nonperfection of any Liens
      on any other collateral for all or any of the Secured Obligations; or

            (d) to the extent permitted by applicable law, any other
      circumstance which might otherwise constitute a defense available to, or a
      discharge of, Company in respect of the Secured Obligations or of this
      Agreement.

            15. Miscellaneous.

            (a) Waiver. Any party hereto may specifically waive any breach of
this Agreement by any other party, but no such waiver shall be deemed to have
been given unless such waiver is in writing, signed by the waiving party and
specifically designating the breach waived, nor shall any such waiver constitute
a continuing waiver of similar or other breaches.

            (b) Invalidity. If for any reason whatsoever any one or more of the
provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of rendering any of the other provisions
of this Agreement inoperative, unenforceable or invalid, and the inoperative,
unenforceable or invalid provision shall be construed as if it were written so
as to effectuate, to the maximum extent possible, the parties' intent.

            (c) Assignment. This Agreement is personal to the parties hereto,
and the rights and duties of any party hereunder shall not be assignable except
with the prior written consent of the other parties. Notwithstanding the
foregoing, this Agreement shall inure to and be binding upon the parties and
their successors and permitted assigns.

            (d) Benefit. The parties hereto and their successors and permitted
assigns, but no others, shall be bound hereby and entitled to the benefits
hereof; provided, however, that the Beneficiaries (including holders of the
Securities) and their assigns shall be entitled to the benefits hereof and to
enforce this Agreement.

            (e) Time. Time is of the essence with respect to each provision of
this Agreement.

            (f) Entire Agreement; Amendments. This Agreement and the Indenture
contain the entire agreement among the parties with respect to the subject
matter hereof and supersede any and all prior agreements, understandings and
commitments, whether oral or written. Any amendment or waiver of any provision
of this Agreement and any consent to any departure by Company from any provision
of this Agreement shall be effective only if made or duly given in compliance
with all of the terms and provisions of the Indenture, and none of Escrow Agent,
Trustee or any Holder of Securities shall be deemed, by any act, delay,
indulgence, omission or otherwise, to have waived any right or remedy hereunder
or to have acquiesced in any De-
<PAGE>   22

                                      -22-


fault or Event of Default or in any breach of any of the terms and conditions
hereof. Failure of Escrow Agent, Trustee or any Holder of Securities to
exercise, or delay in exercising, any right, power or privilege hereunder shall
not operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall not operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Escrow Agent, Trustee or any Holder of Securities of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy that Escrow Agent, Trustee or such Holder of
Securities would otherwise have on any future occasion. The rights and remedies
herein provided are cumulative, may be exercised singly or concurrently and are
not exclusive of any rights or remedies provided by law.

            (g) Notices. All notices and other communications required or
permitted to be given or made under this Agreement shall be in writing and shall
be deemed to have been duly given and received when actually received,
including: (a) on the day of hand delivery; (b) three business days following
the day sent, when sent by United States certified mail, postage and
certification fee prepaid, return receipt requested, addressed as set forth

ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAWS
PROVISIONS) AND DECISIONS OF THE STATE OF NEW YORK.

            (ii) COMPANY AGREES THAT TRUSTEE SHALL, IN ITS CAPACITY AS TRUSTEE
OR IN THE NAME AND ON BEHALF OF ANY HOLDER OF SECURITIES, HAVE THE RIGHT, TO THE
EXTENT PERMITTED BY APPLICABLE LAW, TO PROCEED AGAINST COMPANY OR ITS PROPERTY
IN A COURT IN ANY LOCATION REASONABLY SELECTED IN GOOD FAITH (AND HAVING
PERSONAL OR IN REM JURISDICTION OVER COMPANY OR ITS PROPERTY, AS THE CASE MAY
BE) TO ENABLE TRUSTEE TO REALIZE ON SUCH PROPERTY, OR TO ENFORCE A JUDGMENT OR
OTHER COURT ORDER ENTERED IN FAVOR OF TRUSTEE. COMPANY AGREES THAT IT WILL NOT
ASSERT ANY COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS IN ANY PROCEEDING BROUGHT BY
TRUSTEE TO REALIZE ON SUCH PROPERTY OR TO ENFORCE A JUDGMENT OR OTHER COURT
ORDER IN FAVOR OF TRUSTEE, EXCEPT FOR SUCH COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS

INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON

            (iv) COMPANY AGREES THAT NONE OF ESCROW AGENT, TRUSTEE OR ANY HOLDER
OF SECURITIES SHALL HAVE ANY LIABILITY TO COMPANY (WHETHER SOUNDING IN TORT,
CONTRACT OR OTHERWISE) FOR LOSSES SUFFERED BY COMPANY IN CONNECTION WITH,
ARISING OUT OF, OR IN ANY WAY RELATED TO, THE TRANSACTIONS CONTEMPLATED AND THE
RELATIONSHIP ESTABLISHED BY THIS AGREEMENT, OR ANY ACT, OMISSION OR EVENT
OCCURRING IN CONNECTION THEREWITH, UNLESS IT IS DETERMINED BY A FINAL AND
NONAPPEALABLE JUDGMENT OF A COURT THAT IS BINDING ON ESCROW AGENT, TRUSTEE OR
SUCH HOLDER OF SECURITIES, AS THE CASE MAY BE, THAT SUCH LOSSES WERE THE RESULT
OF ACTS OR OMISSIONS ON THE PART OF ESCROW AGENT,
<PAGE>   25

                                      -25-


TRUSTEE OR SUCH HOLDER OF SECURITIES, AS THE CASE MAY BE, CONSTITUTING BAD

Company or any subsidiary thereof. No such pledge, security or debt agreement
may be used to interpret this Agreement.

            (1) Benefits of Agreement. Nothing in this Agreement, express or
implied, shall give to any person, other than the parties hereto and their
successors hereunder, and the Holders of Securities, any benefit or any legal or
equitable right, remedy or claim under this Agreement.

            (m) Interpretation of Agreement. All terms not defined herein or in
the Indenture shall have the meaning set forth in the applicable Uniform
Commercial Code, except where the context otherwise requires. To the extent a
term or provision of this Agreement conflicts with the Indenture, the Indenture

            (n) Survival of Provisions. All representations, warranties and
covenants of Company contained herein shall survive the execution and delivery
of this Agreement, and shall terminate only upon the termination of this
Agreement.

            (o Waivers. Company waives presentment and demand for payment of
any of the Secured Obligations, protest and notice of dishonor or default with
respect to any of the Secured Obligations, and all other notices to which the
Pledgor might otherwise be entitled, except as otherwise expressly provided
herein or in the Indenture.

            (p) Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. By the execution and delivery of this Agreement, the Company (i)
acknowledges that it has, by separate written instruments, designated and
appointed CT Corporation System, 1633 Broadway, New York, NY 10019 ("CT
Corporation System") (and any successor entity), as its authorized agent upon
which process may be served in any suit or proceeding arising out of or relating
to this Agreement that may be instituted in any federal or state court in the
Borough of Manhattan, City of New York, State of New York or brought under
federal or state securities laws, and represent and warrant that CT Corporation
System has accepted such designation, (ii) submit to the jurisdiction of any
such court in any such suit or proceeding and (iii) agree that service of
process upon CT Corporation System and written notice of said service to the
Company in accordance with the provisions of this Agreement shall be deemed in
every respect effective service of process upon the Company in any such suit or
proceeding. The Company further agrees to take any and all action, including the
execution and filing of any and all such documents and instruments, as may be
necessary to continue such designation and appointment of CT Corporation System
in full force and effect for as long as any of the Securities remain outstanding
(subject to the limitation set forth in clause (i)); provided, however, that the
Company may, and to the extent CT Corporation System ceases to be able to be
served on the basis contemplated herein shall, by written notice to the Escrow
Agent and the Trustee, designate such additional or alternative agent for
service of process that (i) maintains an office located in the Borough of
Manhattan, City of New York, State of New York, and (ii) is either (x) United
States counsel for the Company or (y) a corporate service company which acts as
agent for service of process for other persons in the ordinary course of its
business. Such written notice shall identify the name of such agent for service
of process and the address of the office of such agent for
<PAGE>   27

                                      -27-


service of process in the Borough of Manhattan, City of New York, State of New
York.

            To the extent that the Company has or hereafter may acquire any
immunity from jurisdiction of any court of (i) any jurisdiction in which the
Company owns or leases property or assets, (ii) the United States or the State
of New York or (iii) the Netherlands or from any legal process (whether through
service of notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) with respect to itself or its property and assets or
this Agreement or the Escrow Account or actions to enforce judgments in respect
of any thereof, the Company hereby irrevocably waives such immunity in respect
of its obligations under the above-referenced documents, to the extent permitted
by law.

            (q) Judgment Currency. The Company hereby agrees to indemnify each
of the Escrow Agent and the Trustee, their directors, their officers and each
person, if any, who controls the Escrow Agent or the Trustee, as the case may
be, within the meaning of Section 15 of the Act or Section 20 of the Exchange
Act against any loss incurred by such person as a result of any judgment or
order being given or made against the Company for any U.S. dollar amount due
under this Agreement and such judgment or order being expressed and paid in a
currency (the "Judgment Currency") other than United States dollars and as a
result of any variation as between (i) the rate of exchange at which the United
States dollar amount is converted into the Judgment Currency for the purpose of
such judgment or order and (ii) the spot rate of exchange in The City of New
York at which such party on the date of payment of such judgment or order is
able to purchase United States dollars with the amount of the Judgment Currency
actually received by such party. The foregoing indemnity shall continue in full
force and effect notwithstanding any such judgment or order as aforesaid. The
term "spot rate of exchange" shall include any premiums and costs of exchange
payable in connection with the purchase of, or conversion into, United States
dollars.

Ladies and Gentlemen:

            We refer to the Escrow Agreement, dated as of August 19, 1997 (the

                                   WITNESSETH:

covenants herein set forth, the parties hereto, intending to be legally bound,
hereby agree as follows:

rate of Two Hundred Thirty-Five Thousand Dollars ($235,000) per annum, payable
in accordance with the Corporation's customary payment practices for executive
officers.

      (b) Thereafter, at the end of each year the Compensation Committee of the
Board of Directors of the Corporation shall review the salary of the Executive,
and shall make such increases to such salary as the Board of Directors shall, in
its sole and absolute discretion, deem appropriate.

      (c) For the purposes of this Agreement, "Salary" shall mean any payment by
the Corporation to the Executive pursuant to this Section 3.

      4. Bonus.

Notwithstanding the foregoing, in the event the Hermes Europe business plan is
revised to provide for the capitalization of Hermes Europe on a date subsequent

date of commitments for such capitalization (subject to its completion within
six months thereafter), and one-third of such options shall vest on the close of
business on each of the date of such commitment, and the first and second
anniversaries of the commitment of such financing (in each case subject to
completion of such financing within six months of the commitment for such
financing).

      (b) The Corporation has a Restricted Stock Plan (the "Restricted Plan").
Subject to the provision of the Restricted Plan, the Corporation shall grant to
the Executive Twenty Thousand (20,000) shares of Restricted Stock of the
Corporation ("Restricted Stock") upon achievement of the first year Hermes
Europe Business Plan objectives. The shares shall vest as follows:

      Officer of the Corporation shall be deemed to be continuing if the
      Executive shall have received written notice thereof and shall have not
      terminated the conflict of interest or failure to follow directions within

have no obligation to pay to the Executive his Salary or any other compensation

      11. Covenants of the Executive. In order to induce the Corporation to
enter into this Agreement and employ the Executive hereunder, the Executive
hereby covenants and agrees as follows:

      (a) During the Term and for a period of Twelve (12) months thereafter, the
Executive shall not, without the prior written consent of the Corporation:

            (i) directly or indirectly acquire or own in any manner any interest
      in any person, firm, partnership, corporation, association or other entity
      which competes with the Corporation or any of its affiliates or
      subsidiaries; or

            (ii) be employed by, or serve as an employee, agent, officer,
      director of, any person, firm, partnership, corporation association which
      competes with the Corporation or any of its affiliates or subsidiaries.

The foregoing provisions of this Section 11(a) shall not prevent the Executive
from acquiring and/or owning not more than nine per cent of the equity or debt
securities of any company which has securities listed for trading on a
recognized securities exchange or are regularly traded in the National
Association of Securities Dealers Automated Quotation System.

      (b) The Executive shall not at any time, other than in the ordinary course
of business of the Corporation, when and if required, disclose, directly or
indirectly, to any person, firm, corporation, partnership, association or other
entity, any confidential information relating to the Corporation or any of its
affiliates or subsidiaries, or any information concerning the financial
condition, suppliers, customers, lessors, lessees, sources of leads for and
methods of obtaining new business or the methods generally of doing and
operating the respective businesses of the Corporation, its affiliates and
subsidiaries, except to the extent that such information is a matter of public
knowledge or is required to be disclosed by law or judicial or administrative
process.

      (c) During the Term and for a period of Twelve (12) months thereafter, the
Executive shall not, without the prior written consent of the Corporation,
directly or indirectly through any other individual or entity:

            (i) solicit, entice, persuade or induce any individual who currently
      is, or at any time during the Term shall be, an employee of the
      Corporation, or any of its affiliates, to


                                       7
<PAGE>   8

      terminate or refrain from renewing or extending such person's employment
      with the Corporation or such subsidiary or affiliate, or to become
      employed by or enter into contractual relations with any other individual
      or entity, and the Executive shall not approach any such employee for any
      such purpose or authorize or knowingly cooperate with the taking of any
      such actions by any other individual or entity; or

            (ii) except in accordance with the Executive's duties hereunder on
      behalf of the Corporation, solicit, entice, persuade, or induce any
      individual or entity which currently is, or at any time during the Term
      shall be, a customer, supplier, lessor or lessee of the Corporation, or
      any of its subsidiaries of affiliates, to terminate or refrain from
      renewing or extending its contractual or other relationship with the
      Corporation or such subsidiary or affiliate, and the Executive shall not
      approach any such customer, supplier, lessor or lessee for such purpose or
      authorize or knowingly cooperate with the taking of any such actions by
      any other individual or entity.

      12. Specific Performance. The Executive acknowledges that a breach or
violation by the Executive of the covenants or agreements contained in Section
11 of this Agreement would cause irreparable harm and damage to the Corporation
if such provisions are not specifically enforced, the monetary amount of which
would be impossible to ascertain. Therefore, the Corporation shall be entitled
to enforce such provisions in a court of equity by a decree of specific
performance and to obtain an injunction from any court of competent jurisdiction
enjoining and restraining any breach or violation of any or all of the covenants
and agreements contained in Section 11 of this Agreement by the Executive and/or
his employees, associates, partners or agents, or entities controlled by one or
more of them, either directly or indirectly. Such remedies shall be cumulative
and not exclusive and shall be in addition to whatever other rights or remedies
the Corporation shall have for damages for a breach by the Executive of the
covenants or agreements contained in Section 11 or elsewhere in this Agreement.

      13. Foreign Corrupt Practices Act. The Executive agrees to comply in all
respects with the U.S. Foreign Corrupt Practices Act of 1977 (the "FCPA"), as
amended, which provides generally that: under no circumstances will foreign
officials, representatives, political parties or holders of public offices be
offered, promised or paid any money, remuneration, things of value, or provided
any other benefit, direct or indirect, in connection with obtaining or
maintaining contracts or orders hereunder. The Executive's failure to comply in
all respects with the provisions of the FCPA shall constitute a material breach
by him of his obligations hereunder and shall entitle SFMT to terminate this
Agreement immediately. A copy of the Corporation's FCPA policy is annexed hereto
as Exhibit C.

      14. No Delegation. The Executive shall not delegate his employment
obligations under this Agreement to any other person.

      15. Notices. Any notice required or permitted to be given under this
Agreement shall he in writing and sent by facsimile, with appropriate

however, that the waiver by any party of compliance by any other party with
respect to any provision hereof or of any breach by such other party need be
signed only by the party waiving such provision or breach; provided, further,
that the waiver by either party hereto of a breach or compliance with any
provision of this Agreement shall not operate nor be construed as a waiver of

      Employee Officer of the Corporation. A conflict of interest or a failure
      to follow directions of the Board of Directors or the Chief Employee
      Officer of the Corporation shall be deemed to be continuing if the
      Employee shall have received written notice thereof and shall have not
      terminated the conflict of interest or failure to follow directions within
      Thirty (30) days after receipt of such notice; or

            (iii) an extended period of absence by the Employee from the

such applicable three-month period.

      (c) This Agreement shall terminate automatically upon the date of the
death of the Employee.

      (a) If the Corporation shall terminate the employment of the Employee
under this Agreement pursuant to Section 9 (a) hereof, or if the employment of

have no obligation to pay to the Employee his Salary or any other compensation
or benefits provided under this Agreement for any period after the date of such
termination, or to pay any Bonus for the year in which such termination occurs;
provided, however, that the Corporation shall pay all Salary earned by the
Employee prior to the date of such termination and the reimbursement of all

the provisions of this Agreement, the Corporation shall pay to the Employee or
his Estate, as the case may be, the Salary and Bonus for the fiscal year in
which such termination occurs, prorated for the number of weeks during which the
Employee was employed by the Corporation during such fiscal year.

      (c) In the event that the Corporation terminates the employment of the
Employee by delivering notice in accordance with Section 2, or for any reason
other than those set forth in Section 9 above, the Employee shall receive as
severance an amount equal to the greater of (i) three (3) months salary, and

      (d) In the event that the employment of the Employee is terminated due to
a Total Disability or the death of the Employee in accordance with Section 9
(b) or 9 (c) hereof, then the Employee or his designated beneficiary, as the
case may be, shall be entitled to receive such amounts as are provided for in
any disability policy or life insurance policy provided by the Corporation for
the benefit of the Employee.

      11. Covenants of the Employee. In order to induce the Corporation to enter

      which competes with the Corporation or any of its affiliates or
      subsidiaries; or

            (ii) be employed by, or serve as an employee, agent, officer,
      director of, any person, firm, partnership, corporation association which

      (b) The Employee shall not at any time, other than in the ordinary course
of business of the Corporation, when and if required, disclose, directly or
indirectly, to any person, firm, corporation, partnership, association or other
entity, any confidential information relating to the Corporation or any of its
affiliates or subsidiaries, or any information concerning the financial
condition, suppliers, customers, lessors, lessees, sources of leads for and
methods of obtaining new business or the methods generally of doing and
operating the respective businesses of the Corporation, its affiliates and
subsidiaries, except to the extent that such information is a matter of public
knowledge or is required to be disclosed by law or judicial or administrative
process.

      (c) During the Term and for a period of twelve (12) months thereafter, the
Employee shall not, without the prior written consent of the Corporation,
directly or indirectly through any other individual or entity:

            (i) solicit, entice, persuade or induce any individual who currently
      is, or at any time during the Term shall be, an employee of the
      Corporation, or any of its affiliates, to terminate or refrain from
      renewing or extending such person's employment with the Corporation or
      such subsidiary or affiliate, or to become employed by or enter into
      contractual relations with any other individual or entity, and the
      Employee shall not approach any such employee for any such purpose or
      authorize or knowingly cooperate with the taking of any such actions by
      any other individual or entity; or


                                       6
<PAGE>   7

            (ii) except in accordance with the Employee's duties hereunder on
      behalf of the Corporation, solicit, entice, persuade, or induce any
      individual or entity which currently is, or at any time during the Term
      shall be, a customer, supplier, lessor or lessee of the Corporation, or
      any of its subsidiaries of affiliates, to terminate or refrain from
      renewing or extending its contractual or other relationship with the
      Corporation or such subsidiary or affiliate, and the Employee shall not
      approach any such customer, supplier, lessor or lessee for such purpose or
      authorize or knowingly cooperate with the taking of any such actions by
      any other individual or entity.

      12. Specific Performance. The Employee acknowledges that a breach or
violation by the Employee of the covenants or agreements contained in Section 11
of this Agreement would cause irreparable harm and damage to the Corporation if
such provisions are not specifically enforced, the monetary amount of which
would be impossible to ascertain. Therefore, the Corporation shall be entitled
to enforce such provisions in a court of equity by a decree of specific
performance and to obtain an injunction from any court of competent jurisdiction
enjoining and restraining any breach or violation of any or all of the covenants
and agreements contained in Section 11 of this Agreement by the Employee and/or
his employees, associates, partners or agents, or entities controlled by one or
more of them, either directly or indirectly. Such remedies shall be cumulative
and not exclusive and shall he in addition to whatever other rights or remedies
the Corporation shall have for damages for a breach by the Employee of the
covenants or agreements contained in Section 11 or elsewhere in this Agreement.

      13. Foreign Corrupt Practices Act. The Employee agrees to comply in all
respects with the U.S. Foreign Corrupt Practices Act of 1977 (the "FCPA"), as
amended, which provides generally that: under no circumstances will foreign
officials, representatives, political parties or holders of public offices be
offered, promised or paid any money, remuneration, things of value, or provided
any other benefit, direct or indirect, in connection with obtaining or
maintaining contracts or orders hereunder. The Executive's failure to comply in
all respects with the provisions of the FCPA shall constitute a material breach
by him of his obligations hereunder and shall entitle SFMT to terminate this
Agreement immediately. A copy of the Corporation's FCPA policy is annexed hereto
as Exhibit A.

      14. No Delegation. The Employee shall not delegate his employment
obligations under this Agreement to any other person.

      15. Notices. Any notice required or permitted to be given under this

signed only by the party waiving such provision or breach; provided, further;
that the waiver by either party hereto of a breach or compliance with any
provision of this Agreement shall not operate nor be construed as a waiver of

            (i) fraud, embezzlement or any felony in connection with the
      Employee's duties as an Employee officer of the Corporation or any

      of this Agreement;

            (ii) a continuing conflict of interest or continuing failure to
      follow reasonable directions or instructions of the Board of Directors or
      Chief Executive Officer of the Corporation. A conflict of interest or a
      failure to follow directions of the Chief Executive Officer of the
      Corporation shall be deemed to be continuing if the Employee shall have
      received written notice thereof and shall have not terminated the conflict
      of interest or failure to follow directions within thirty days after
      receipt of such notice;

            (iii) an extended period of absence by the Employee from the
      performance of the obligations of the Employee provided hereunder, which

death of the Employee.

      (d) The Employee may terminate the Agreement at any time by giving 120
days written notice to the Corporation in accordance with Section 15. Upon
giving such notice, the Employee shall be continued in employment with the
Corporation for the full 120 days of the notice period, be continued in
employment with the Corporation without the existence of an employement
agreement, or at the discretion of the Corporation may be paid the Employee's
salary and have applicable benefits hereunder continued for such 120 days period
in lieu of continued employment. Failure of the Employee to provide the full 120
days notice shall be deemed a breach of the agreement by the Employee and permit
the Corporation to cease immediately the compensation and benefits provided
herein, and if deemed necessary, to take remedial action to prohibit any further
damages as may occur from the breach by the Employee.

      10.   Payments Upon Termination.

      (a) If the Corporation shall terminate the employment of the Employee
under this Agreement pursuant to Section 9(a) hereof, or if the employment of
the Employee hereunder shall be terminated by the Employee other than in
accordance with Section 2 or Section 9(d), then, in any such event, the
Corporation shall have no obligation to pay to the Employee base salary or any
other compensation or benefits provided under this Agreement for any period
after the date of such termination, or to pay any Bonus for the year in which
such termination occurs; provided, however, that the Corporation shall pay all
Salary earned by the Employee prior to the date of such termination and the
reimbursement of all expenses incurred by the Employee prior to the date of such
termination in accordance with Section 7 hereof. Upon termination pursuant to
Section 9(a) or by the Employee other than in accordance with Section 2 or
Section 9(d), all options granted to the Employee pursuant to Section 5 shall
immediately be canceled and no further options shall vest.

      (b) If the employment of the Employee hereunder shall terminate pursuant
to subsections 9(b) or (c) hereof, if the employment of the Employee shall be
terminated by the Corporation in accordance with Section 2 hereof, or if the
Employee shall be terminated by the Corporation other than in accordance with
the provisions of this Agreement, the Corporation shall pay to the Employee or
the Employee's Estate, as the case may be, the Salary and target Bonus for the
fiscal year in which the termination occurs, prorated for the number of weeks
during which the Employee was employed by the Corporation during such fiscal
year.

      (c) In the event that the Corporation terminates the employment of the
Employee by delivering notice in accordance with Section 2, or for any reason
other than those set forth in Section 9 above, the Employee shall receive as
severance an amount equal to 120 days of Salary and benefits. Such severance pay
shall be paid in equal monthly installments, commencing the month following such
termination, and shall be payable in accordance with the Corporation's customary

<PAGE>   6
      (d) In the event that the employment of the Employee is terminated due to
a Total Disability or the death of the Employee in accordance with Section 9(b)
or 9(c) hereof, then the Employee or his designated beneficiary, as the case may
be, shall receive such amounts as are provided for in the disability policy or
life insurance policy provided by the Corporation for the benefit of the
Employee.

      11. Covenants of the Employee. In order to induce the Corporation to enter
into this Agreement and employ the Employee hereunder, the Employee hereby
covenants and agrees as follows:

      (a) During the term and for a period of twelve months thereafter, the
Employee shall not, without the prior written consent of the Corporation,
directly or indirectly, own, acquire, manage, operate, join, control, finance or
participate in the ownership, management, operation, control or financing of, or
be connected as an officer, director, employee, partner, principal, agent,
representative, consultant or otherwise with or use or permit his/her name to be
used in connection with:

            (i) any business or enterprise engaged in the business of providing
      carrier's carrier services in the European Union, including but not
      limited to the following businesses or enterprises: AT&T/Unisource,
      /Atlas, Phoenix (this subparagraph shall include any business operations
      and activities that Hermes will expand into after the date this agreement
      is extended); and

            (ii) in a geographic area in which the Corporation or any of its
      affiliates is operating either during the term or on the date Employee's
      employment terminates and within which the Employee provides services or
      has responsibility for the business operations and activities of the
      Corporation, including but not limited to the following: the member states
      of the European Union and the EFTA (including any area into which the
      Corporation's business operations or activities expand after the date
      hereof and within which the Employee provides services or as
      responsibility for such business operations or activities) (the
      "Geographic Area).

      It is recognized by the Employee that the business of the Corporation,
Hermes, and their respective affiliates and the Employee's connection therewith
is or will be involved in activity throughout the Geographic Area and that more
limited geographical limitations on this non-competition covenant are therefore
not appropriate.

      The foregoing provisions of this Section 11(a) shall not prevent the
Employee from acquiring and/or owning not more than nine per cent of the equity
or debt securities of any company which has securities listed for trading on a
recognized securities exchange or are regularly traded in the National
Association of Securities Dealers Automated Quotation System.

      (b) The Employee shall not at any time, other than in the ordinary course
of business of the Corporation, when and if required, disclose, directly or
indirectly, to any person, firm, corporation, partnership, association or other
entity, any confidential information concerning the financial condition,
suppliers, customers, lessors, lessees, sources of leads for and methods of
obtaining new business or the methods generally of doing and operating the
respective businesses of the Corporation, its affiliates and subsidiaries,
except that such information is a matter of public knowledge or is required to
be disclosed by law or judicial or administrative process.


                                       6
<PAGE>   7

      (c) During the Term and for a period of twelve months thereafter, the
Employee shall not, without the prior written consent of the Corporation,
directly or indirectly through any other individual or entity:

            (i) solicit, entice, persuade or induce any individual who currently
      is, or at any time during the Term shall be, an employee of the
      Corporation, or any of its affiliates, to terminate or refrain from
      renewing or extending such person's employment with the Corporation or
      such subsidiary or affiliate, or to become employed by or enter into
      contractual relations with any other individual or entity, and the
      Employee shall not approach any such employee for any such purpose or
      authorize or knowingly cooperate with the taking of any such actions by
      any other individual or entity; or

            (ii) except in accordance with the Executive's duties hereunder on
      behalf of the Corporation, solicit, entice, persuade, or induce any
      individual or entity which currently is, or at any time during the Term
      shall be, a customer, supplier, lessor or lessee of the Corporation, or
      any of its subsidiaries or affiliates, to terminate or refrain from
      renewing or extending its contractual or other relationship with the
      Corporation or such subsidiary or affiliate, and the Employee shall not
      approach any such customer, supplier, lessor or lessee for such purpose or
      authorize or knowingly cooperate with the taking of any such actions by
      any other individual or entity.

      12. Specific Performance. The Employee acknowledges that a breach or
violation by the Employee of the covenants or agreements contained in Sections
11 and 13 of this Agreement would cause irreparable harm and damage to the
Corporation if such provisions are not specifically enforced, the monetary
amount of which would be impossible to ascertain. Therefore, the Corporation
shall be entitled to enforce such provisions in a court of equity by a decree of
specific performance and to obtain an injunction from any court of competent
jurisdiction enjoining and restraining any breach or violation of any or all of
the covenants and agreements contained in Sections 11 and 13 of this Agreement
by the Employee and/or his employees, associates, partners or agents, or
entities controlled by one or more of them, either directly or indirectly. Such
remedies shall be cumulative and not exclusive and shall be in addition to
whatever other rights or remedies the Corporation shall have for damages for a
breach by the Employee of the covenants or agreements contained in Section 11 or
elsewhere in this Agreement. Notwithstanding anything herein to the contrary,
the Corporation hereby expressly reserves the right to seek damages and other
economic remedies for a breach by the Employee of the covenants or agreements
contained in Section 11 or elsewhere in this Agreement.

      13. Foreign Corrupt Practices Act. You agree to comply in all respects
with the U.S. Foreign Corrupt Practices Act of 1977 (FCPA), as amended, which
provides generally that: under no circumstances will foreign officials,
representatives, political parties or holders of public offices be offered,
promised or paid any money, remuneration, things of value, or provided any other
benefit, direct or indirect, in connection with obtaining or maintaining
contracts or orders hereunder. Your failure to comply in all respects with the
provisions of the FCPA shall constitute a material breach by you of your
obligations hereunder and shall entitle SFMT to terminate this Agreement
immediately. A copy of the Corporation's FCPA policy is annexed hereto as
Exhibit C:

      14. No Delegation. The Employee shall not delegate his employment
obligations under this Agreement to any other person.

            telecommunication systems connected to the operator's system and
            persons running telecommunication systems connected to the
            Applicable Systems to exercise freedom of choice as to the extent to
            which Messages are conveyed by means of the Applicable Systems and
            in routing Messages so conveyed; and

      (c)   to provide such other telecommunication services (including the
            conveyance of Messages which have been, or are to be, transmitted or
            received at such Points of Connection), information and other
            services as the Director determines are reasonably required (but no
            more than reasonably required) to secure that Points of Connection
            are established and maintained and to enable the Operator
            effectively to provide the Connection Services which he provides or
            proposes to provide.

5.2   The Licensee shall not be obliged under paragraph 5.1 to enter into an
agreement to do anything or agree to amend such an agreement to do anything if:

      (a)   in the opinion of the Licensee it would be liable to cause the death
            of or personal injury to, or damage to the property of, the Licensee
            or any person engaged in the Licensee's business, or materially to
            impair the quality of any telecommunication service provided by
            means of the Applicable Systems or
<PAGE>   22
                                       18


            any telecommunication system (other than the Operator's system)
            connected thereto and the Director has not expressed a contrary
            opinion; or

      (b)   in the opinion of the Licensee:

            (i)   it would require an adjustment to, or modification of, the
                  Applicable Systems whether by incorporation of apparatus or
                  otherwise or the provision by the Licensee of services or
                  information which in any particular case would not be
                  reasonably required; or

            (ii)  it would not be reasonably practicable to require the Licensee
                  to do that thing, or permit it to be done, at the time or in
                  the manner required by the Operator, having regard to the
                  state of technical development of the Applicable Systems or
                  any other relevant matter,

            and the Director has not expressed a contrary opinion.

5.3   The Licensee may require that an agreement under paragraph 5.1 should be
subject to such terms and conditions as are, in the opinion of the Director,
reasonable.

5.4   Apparatus shall not be regarded as approved for connection to any system
for the purposes of paragraph 5.1 unless that apparatus is Compliant Terminal
Equipment or has been so approved:

      (a)   by the Secretary of State; or

      (b)   by some other person by virtue of an authorisation given by the
            Secretary of State being an authorisation which required the person
            authorised, before approving any apparatus or designating any
            standard to which apparatus must conform if it is to be approved, to
            be satisfied that connection of the apparatus to the system would
            not be likely:

            (i)   to cause the death of, or personal injury to, or damage to the
                  property of the Licensee or any person engaged in the running
                  of that system; or

            (ii)  materially to impair the quality of any telecommunication
                  service provided by means of that system or any system
                  connected to it (other than the system being connected).

5.5   No apparatus or system is required under paragraph 5.1 to be, or to be
permitted to be, connected or kept connected to the Applicable Systems if the
apparatus, or any apparatus comprised in that system, as the case may be:

      (a)   conformed to the relevant standard or standards at the time when the
            connection to the Applicable Systems was made but no longer does so
            and does not conform to the relevant standard or standards (if any)
            for the time being designated under section 22(6) of the Act; or
<PAGE>   23
                                       19


      (b)   was at the time when the connection to the Applicable Systems was
            made but has since ceased to be Complaint Terminal Equipment; or

      (c)   while continuing to conform to the relevant standard is in the
            opinion of the Licensee liable to cause the death of, or personal
            injury to, or damage to the property of, the Licensee, or any person
            engaged in the running of the Applicable Systems or materially to
            impair the quality of any telecommunication service provided by
            means of the Applicable Systems and the Director has not directed
            otherwise.

5.6   An agreement made pursuant to this Condition shall not contain any
restrictive provision unless, before the agreement is made, the Director has
expressly consented to the inclusion of such a provision. For the purposes of
this paragraph, a provision in an agreement is a restrictive provision if by
virtue of the existence of such a provision (taken alone or with other
provisions) the agreement is one to which the Restrictive Trade Practices Act
1976 would apply but for paragraph 1(1) of Schedule 3 to that Act.

5.7   Where the Director so directs the Crown shall be treated for the purposes
of this Condition as a person authorised to run a Relevant Connectable System
and where he does so he may also direct that the Crown is to be treated as a
Long Line Public Telecommunications Operator for those purposes.

PROVISION BY OTHERS OF SERVICES BY MEANS OF THE APPLICABLE SYSTEMS

6.1   The Licensee shall permit any person, who is licensed to run a Connectable
System under a Licence which authorises it to provide telecommunication services
to others, including Connection Services, to provide such services whilst that
Connectable System is connected to the relevant Applicable System.

6.2   The Licensee shall permit any person:

      (a)   using telecommunication apparatus which has been lawfully connected
            to the Applicable Systems or which is connected to another
            telecommunication system which itself has been lawfully connected to
            the Applicable Systems; or

      (b)   running a telecommunication system which is so connected,

to provide by means of the Applicable Systems any service other than the
installation, maintenance, adjustment, repair, alteration, moving, removal or
replacement of telecommunication apparatus comprised in the Applicable Systems.

PUBLICATION OF CHARGES, TERMS AND CONDITIONS TO BE APPLIED

7.1   The Licensee shall subject to paragraph 7.2, except insofar as the
Director may otherwise consent in writing and except in respect of charges,
terms and conditions in agreements made or modified to comply with Condition 5:

      (a)   publish in the manner and at the times specified in paragraph 7.4 a
            notice specifying, or specifying the method that is to be adopted
            for determining, the charges and other terms and conditions on which
            it offers:

            (i)   to provide each description of telecommunication services by
                  means of the Applicable Systems; or

            (ii)  to maintain, adjust, repair or replace any apparatus comprised
                  in the Applicable Systems; or

            (iii) to connect to the Applicable Systems any other system which is
                  not and is not to be comprised in the Applicable Systems; or

            (iv)  to grant permission to connect such systems to, or to provide
                  services by means of the Applicable Systems;

            where such things are done in accordance with an obligation imposed
            by or under this Licence.

      (b)   Where the Licensee does any of the things described in paragraphs
            7.1(a)(i) to 7.1(a)(iv) it shall do those things at the charges and
            on the other terms and conditions so published and not depart
            therefrom. Provided that this obligation will not be breached by
            variations to the charges, terms and conditions referred to in
            paragraph 7(1)(z) to the extent that the method which is adopted for
            determining those variations has been disclosed to the Director,
            except insofar as those charges, terms and conditions relate to a
            particular market in respect of which the Director has made a
            determination that the Licensee is a Well Established International
            Operator.

7.2   Where the Director has made a determination that the Licensee is a Well
Established International Operator in a particular market the Licensee shall
specify the precise amount of such charges in accordance with paragraph 7.1(a),
insofar as they relate to the market in respect of which such a determination
has been made.

7.3   The requirement to publish under paragraph 7.1 shall not apply in respect
of any service which is materially different from any service already provided
by the Licensee by means of the Applicable Systems until such time as it is
provided and a copy of the notice shall be sent to the Director at that time.
<PAGE>   26
                                       22


7.4   Publication of the notice shall be effected by:

      (a)   sending a copy thereof to the Director to arrive not more than 28
            days after the date on which the Licensee first provides services
            under the Licence and thereafter not less than one day before any
            proposal to amend any charge, term or condition or the method of
            determining the same is to become effective; provided that where the
            Director has made a determination that the Licensee is a Well
            Established International Operator in a particular market, this sub-
            paragraph shall have effect as if the words "28 days" were
            substituted for the words "one day" insofar as any such proposal
            relates to the provision of services in relation to the market in
            respect of which such a determination has been made;

      (b)   placing as soon as practicable thereafter a copy thereof in a
            publicly accessible part of every Major Office of the Licensee in
            such a manner and in such a place that it is readily available for
            inspection free of charge by members of the general public during
            such hours as the Secretary of State may by order prescribe under
            section 19(4) of the Act that the register of Licences and final and
            provisional orders is to be open to public inspection, or in the
            absence of any such order having been made by the Secretary of
            State, during normal office hours; and

      (c)   sending a copy thereof or such part or parts thereof as are
            appropriate to any person who may request such a copy.

7.5   The obligations imposed on the Licensee by this Condition are without
prejudice to any determination which the Director may make under Condition 9 of
this Licence.

PROHIBITION ON UNDUE PREFERENCE AND UNDUE DISCRIMINATION

8.1   The Licensee shall not (whether in respect of the charges or other terms
or conditions applied or otherwise) show undue preference to, or exercise undue
discrimination against, particular persons or persons of any class or
description as respects:

      (a)   the connection to the Applicable Systems of any other system which
            is not and is not to be comprised in the Applicable Systems in
            accordance with an obligation imposed by or under this Licence; or

      (b)   the maintenance, adjustment, repair or replacement of any apparatus
            comprised in the Applicable Systems in accordance with an obligation
            imposed by or under this Licence; or

      (c)   the provision by means of the Applicable Systems of any
            telecommunication service in accordance with an obligation imposed
            by or under this Licence; or

      (d)   the granting of permission to connect such systems to, or to provide
            services by means of the Applicable Systems in accordance with an
            obligation imposed by or under this Licence.

8.2   The Licensee may be deemed to have shown such undue preference or to have
exercised such undue discrimination if it unfairly favours to a material extent
a business carried on by it in relation to the doing of any of the things
mentioned in paragraph 8.1 so as to place at a significant competitive
disadvantage persons competing with that business.

8.3   Any question relating to whether any act done or course of conduct pursued
by the Licensee amounts to such undue preference or such undue discrimination
shall be determined by the Director, but nothing done in any manner by the
Licensee shall be regarded as undue preference or undue discrimination if and to
the extent that the Licensee is required or permitted to do the thing in that
manner by or under any provision of this Licence.

8.4   The obligations imposed on the Licensee by this Condition are without
prejudice to any determination which the Director may make under Condition 9 of
this Licence.

PART 3:     OTHER CONDITIONS INCLUDED UNDER SECTION 7 OF THE ACT

                                                                     Condition 9

MAINTENANCE OF EFFECTIVE COMPETITION WHERE THE LICENSEE
OPERATES A SYSTEM OR PROVIDES SERVICE OVERSEAS

9.1   This Condition shall apply where the Licensee or any Associated Person is
the operator of any telecommunication system or provides telecommunication
services in a country or territory outside the United Kingdom.

9.2   Where it appears to the Director that as a result of any act or omission
of the Licensee either by itself or with or through any Associated Person
competition in the provision of any telecommunication service or any particular
description of telecommunication services in the United Kingdom is being or is
likely to be restricted, distorted or prevented he may make a determination to
that effect.

9.3   Where the Director makes a determination under paragraph 9.2 the Licensee
shall take such steps as the Director may direct for the purpose of remedying
the situation. In particular (and without prejudice to the generality of the
foregoing) any such direction may require compliance by the Licensee with any
other Condition, as appropriate, including in particular any Condition providing
for publication of charges, terms and conditions or prohibiting undue
discrimination and undue preference, in relation to the provision of any
telecommunication service within the United Kingdom notwithstanding that any
condition precedent to the application of that Condition is not otherwise
satisfied.

                                                                    Condition 10

FAIR TRADING

10.1  The Licensee shall not do any thing, whether by act or omission, which has
or is intended to have or is likely to have the effect of preventing,
restricting or distorting competition where such act or omission is done in the
course of, as a result of or in connection with, providing telecommunication
services, or any particular description of telecommunication service, or running
a telecommunication system.

For the purpose of this Condition such an act or omission will take the form
of:-

      (a)   any abuse by the Licensee, either alone or with other undertakings,
            of a dominant position within the United Kingdom or a substantial
            part of it. Such abuse may, in particular, consist in:

            (i)   directly or indirectly imposing unfair purchase or selling
                  prices or other unfair trading conditions;

            (ii)  limiting production, markets or technical development to the
                  prejudice of consumers;

            (iii) applying dissimilar conditions to equivalent transactions with
                  other parties, thereby placing them at a competitive
                  disadvantage; or

            (iv)  making the conclusion of contracts subject to acceptance by
                  the other parties of supplementary obligations which, by their
                  nature or according to commercial usage, have no connection
                  with the subject of such contracts; or

      (b)   the making (including the implementation) of any agreement, the
            compliance with any decision of any association of undertakings or
            the carrying on of any concerted practice with any other undertaking
            which has the object or effect of preventing, restricting or
            distorting competition within the United Kingdom.

10.2  (a)   An act or omission of a kind described in paragraph 10.1 is not
            prohibited where:

            (i)   it has or would have no appreciable effect on competition; or

            (ii)  it has or would have no effect on competition between persons
                  engaged in commercial activities connected with
                  telecommunications and it would have no effect on users of
                  telecommunication services.

      (b)   An act or omission of a kind described in paragraph 10.1(b) is not
            prohibited by this Condition if the agreement decision or concerted
            practice contributes to improving the provision of any goods or
            services or to promoting technical or
<PAGE>   30
                                       26


            economic progress, while allowing consumers a fair share of the
            resulting benefit and does not:

            (i)   impose on the parties concerned restrictions which are not
                  indispensable to attaining those objectives; and

            (ii)  afford such parties the possibility of eliminating competition
                  in respect of a substantial part of the goods or services in
                  question.

      (c)   This Condition shall not apply to any provision of an agreement
            insofar as it is a provision by virtue of which the Restrictive
            Trade Practices Act 1976 applies to that agreement.

      (d)   This Condition shall not apply to a merger situation qualifying for
            investigation under the Fair Trading Act 1973.

10.3  Whether any act or omission is prohibited by this Condition shall be
determined:-

      (a)   with a view to securing that there is no inconsistency with the
            general principles having application to similar questions of
            directly applicable competition law, in particular those laid down
            by the Court of Justice of the European Communities on the scope of
            the competition rules contained in the EC Treaty and block
            exemptions adopted by the European Commission under Article 85(3);
            and

      (b)   having regard to -

            (i)   any decision taken, or notice issued, by the European
                  Commission in applying the competition rules contained in the
                  EC Treaty and any relevant pronouncement of the Director
                  General of Fair Trading or report of the Monopolies and
                  Mergers Commission; and

            (ii)  any guidelines on the application of this Condition issued
                  from time to time by the Director.

10.4  (a)   If it appears to the Director that an act or omission of the
            Licensee is or was prohibited by this Condition he may make an
            initial determination to that effect (an "Initial Determination").

      (b)   Before making an Initial Determination the Director shall give a
            notice to the Licensee:

            (i)   stating that he is investigating a possible contravention of
                  this Condition;
<PAGE>   31
                                       27


            (ii)  setting out the reasons why it appears to him that this
                  Condition may be being, or may have been, breached, including
                  any matters of fact or law which he thinks relevant;

            (iii) requesting within a reasonable period laid down by the
                  Director such further information as he may require from the
                  Licensee in order to complete his Determination; and

            (iv)  where appropriate, setting out the steps he believes the
                  Licensee would have to take in order to remedy the alleged
                  breach.

10.5  (a)   Within 28 days of the Director -

            (i)   making an Initial Determination;

            (ii)  making a provisional order; or

            (iii) giving notice of his proposal to make a final order under
                  section 17(1) of the Act

            in respect of the contravention in question, the Licensee may notify
            the Director that it -

            (iv)  requires him to make a final determination (a "Final
                  Determination") of the matter;

            (v)   requires that in making the Final Determination he take into
                  account a report of a body of experts appointed by him to
                  consider the matter ("the Advisory Body").

      (b)   Before making a Final Determination the Director shall -

            (i)   give a notice to the Licensee setting out the matters referred
                  to in paragraph 10.4(b); and

            (ii)  if the Licensee has given notice under sub-paragraph (a) (v)
                  above, take into account the report of the Advisory Body on
                  the matter.

      (c)   The Director shall then determine whether he is satisfied that the
            act or omission in respect of which the Initial Determination was
            made is or was prohibited by this Condition.

10.6  (a)   Before making his Initial Determination or Final Determination the
            Director shall give the Licensee, and any other person whom he
            considers it appropriate to consult, such period within which to
            make representations (both orally and in writing) in response to the
            notice as he considers reasonable in all the circumstances.
<PAGE>   32
                                       28


      (b)   The Director shall notify the Licensee and any other person whom he
            considers it appropriate to notify of every Initial Determination
            and Final Determination made by him and of his reasons for making
            it; and he shall, if so requested by the Licensee, publish any
            report of the Advisory Body on the matter, subject to such
            exclusions as he may consider it appropriate to make of matters of a
            kind mentioned in section 48(2) of the Act.

10.7  The Director shall publish a description of his office's procedures for
the enforcement of this Condition including the steps taken to ensure that he
has access to appropriate independent advice in enforcing this Condition.

10.8  This Condition shall not limit or affect in any way the Licensee's
obligations arising under any other Condition of this Licence nor limit the
Director's powers of enforcement under sections 16 to 18 of the Act.

10.9  (a)   On the coming into force of any Act or subordinate legislation which
            -

            (i)   contains a prohibition enforceable by the Director, or gives
                  to the Director the power to enforce an existing prohibition,
                  of any behaviour prohibited under paragraph 10.1;

            (ii)  gives to third parties in respect of a breach of that
                  prohibition at least the rights they have under section 18 of
                  the Act in respect of a breach of a provisional or final
                  order; and

            (iii) permits the imposition on the Licensee of monetary, penalties
                  in respect of the breach of that prohibition

            this Condition shall cease to apply to the behaviour prohibited by
            or the prohibition enforceable by such Act or subordinate
            legislation.

ESSENTIAL INTERFACES

11.1 This Condition operates without prejudice to the provisions of Condition 5.

11.2 The Director may, having first notified the Licensee of his proposal and
given the Licensee not less than 28 days in which to make representations,
specify an Essential Interface.

11.3 Where in pursuance of paragraph 11.2 the Director specifies an interface as
an Essential Interface, and the Licensee thereafter makes that interface
available to an Operator in relation to its Applicable Systems, it shall do so
in such a manner as it considers appropriate, but shall ensure such availability
in compliance with a Relevant Standard if the Operator so requires.

11.4 For the purposes of paragraph 11.3 "Relevant Standard" means:

     (a)  an appropriate European or other international standard; or

     (b)  in the absence of such a standard, any other standard specified by the
          Director after he has notified the Licensee of his proposal to make
          the specifications in question and allowed the Licensee not less than
          28 days in which to make representations, provided that the Director
          shall not specify a standard if an appropriate European or other
          international standard is expected to be promulgated within a
          reasonable time, including, by way of example, if the European
          Telecommunications Standards Institute have published a work programme
          for the development of such a standard.

to the extent that such a standard is necessary to ensure interoperability.

11.5 Where in pursuance of paragraph 11.4(b) the Director specifies a standard
as a Relevant Standard, he shall include in that Relevant Standard a technical
specification, using all reasonable endeavours to obtain the agreement of the
Licensee and other relevant licensees to a technical specification applicable to
that Relevant Standard, being a specification defined if possible by reference 
to:

     (a)  an appropriate European or other international specification; or

     (b)  in the absence of such a specification, a specification defined by
          reference to any other standard having currency within the European
          Community at the time.

11.6 Where after a reasonable time the Director has been unable in accordance
with paragraph 11.5 to secure the agreement of the Licensee and other relevant
licensees to a technical specification, the Director shall adopt for inclusion
in the Relevant Standard an appropriate technical specification which has been
promulgated by a recognised standards

                                       30


body, including, by way of example, the European Telecommunications Standards
Institute, or the British Standards Institution, or other such body as the
Director considers to be representative of all relevant telecommunications
interests.

11.7 The Director shall specify a Relevant Standard in pursuance of paragraph
11.4 only if the owners of relevant intellectual property rights have agreed to
grant any necessary licences in respect thereof to the Licensee on reasonable
terms.

11.8 For the avoidance of doubt this Condition shall not:

     (a)  without prejudice to paragraph 11.3, prevent the Licensee using such
          interfaces as it considers appropriate in relation to the Applicable
          Systems; or

     (b)  where it makes available to an Operator an interface which the
          Director has specified as an Essential Interface, require the Licensee
          to comply with the Relevant Standard if the Operator does not require
          it to do so.

11.9 When implementing an Essential Interface, the Licensee shall not be obliged
to conform with the Relevant Standard:

     (a)  if to do so would necessitate the Licensee:

          (i)  acquiring apparatus, software or other goods or supplies of any
               kind, or implementing any operation, incompatible with, as the
               case may be, apparatus, software or such other goods or supplies
               already in use at the time, or the subject of contracts for their
               procurement for use, in connection with the Applicable Systems,
               or, in the case of an operation, incompatible with any other
               operation being carried out at the time in connection therewith;
               or

          (ii) incurring any cost, or having to resolve technical difficulties,
               disproportionate to the benefits to be gained from the
               implementation of the Relevant Standard,

          provided that the Licensee shall take reasonable steps to incorporate
          the Relevant Standard in its plans for network development, with a
          view to implementation of that Standard in connection with the
          Applicable Systems, but without the Licensee incurring any incremental
          expenditure which, but for the implementation of the Relevant
          Standard, would not have been incurred;

     (b)  if the Relevant Standard is inappropriate for the particular
          application for any reason, including, without limitation:

          (i)  that it does not afford the Licensee adequate protection for the
               security of the Applicable Systems;
<PAGE>   35

                                       31


          (ii) that its implementation would be liable to cause material
               impairment in the quality of any telecommunication service
               provided by means of the Applicable Systems;

          (iii) that it does not cater adequately for billing, metering or other
                customer administration systems; or

          (iv) that it is technically inadequate in the light of technical
               developments which have taken place since it was originally
               created;

     (c)  if the Essential Interface concerned is of a genuinely innovative
          nature and accordingly the use in connection with it of the Relevant
          Standard would not be appropriate;

     (d)  if compliance with the Relevant Standard would involve the
          infringement by the Licensee of any intellectual property right vested
          in any person; or

     (e)  if the Director so agrees.

11.10 Where paragraph 11.9(b) or 11.9(c) applies, the Licensee shall notify the
Director thereof in writing, providing an explanation why.

11.11 It is a precondition of any obligation on the Licensee under this
Condition that an equivalent Condition to this Condition is included in the
respective Licences of all Operators running telecommunication systems that are
connected to the Applicable Systems.

CUSTOMER INTERFACE STANDARDS

12.1 This Condition shall only apply where the Applicable Systems are connected
to a telecommunication system not run under a licence issued to a particular
person.

12.2 The Licensee shall ensure that on each occasion on which it introduces an
interface provided or to be provided at a Network Termination Point on the
Applicable Systems not previously so provided a notice is published specifying
the technical characteristics of the interface introduced.

12.3 The technical characteristics to be included in such a notice shall
include:

     (a)  physical, electrical and other relevant characteristics;

     (b)  network interworking and service management protocols; and

     (c)  reference to national and international standards and recommendations
          with which the interface complies.

in sufficient detail for compatible terminal apparatus to be produced, tested
and approved.

12.4 Subject to paragraph 12.5, any notice under this Condition shall be
published in a manner appropriate for bringing the matters to which the notice
relates to the attention of persons likely to be affected by or to have an
interest in them.

12.5 Where the Director following any representation or observation made to him
reasonably concludes that a notice under paragraph 12.2 has not been published
in an appropriate manner he may direct the Licensee to carry out such further
publication as he considers reasonably necessary to meet the requirements of
paragraph 12.4.

METERING AND BILLING ARRANGEMENTS

13.1 This Condition shall only apply where the Applicable Systems are connected
to a telecommunication system not run under a Licence issued to a particular
person.

13.2 As regards any description of Meter in use on a date specified by the
Director in connection with the Applicable Systems and which has been specified
by the Director, the Licensee shall apply for Approval as soon as is practicable
and in any case not later than such date as the Director may determine in
relation to that description of Meter.

13.3 As regards any description of Meter specified by the Director and not in
use in connection with the Applicable Systems on the date specified under
paragraph 13.2, the Licensee shall, unless the Director consents otherwise,
apply for Approval not later than such date as is further specified by the
Director or not fewer than six months before the date on which the Licensee
intends to bring that Meter into such use, whichever shall be the later.

13.4 The Licensee shall not after such date as the Director may determine in
relation to any description of Meter so specified by him, keep in use or bring
into use in connection with the Applicable systems, any Meter of a description
so specified which is not Approved or for which the Licensee has not made an
application for Approval.

13.5 Where Approval is not granted to or is withdrawn from a particular
description of Meter the Licensee shall, as soon as is reasonably practicable,
either;

     (a)  inform the Director of the action to be taken by the Licensee to
          remedy the absence of Approval in relation to that description of
          Meter and the anticipated date of such Approval; or

     (b)  inform the Director that the Licensee intends to cease use of that
          description of Meter in connection with the Applicable Systems within
          a time reasonably practicable for the Licensee whereupon, on request
          of the Director, the Licensee shall provide the Director with a
          timetable for the withdrawal of that description of Meter.

13.6 The Licensee shall not render any bill in respect of any description of
telecommunication Service provided by means of the Applicable Systems unless
every amount (other than an indication of unit charge) stated in that bill is no
higher than an amount which represents the true extent of any such Service
actually provided by the Licensee to the customer in question. In this paragraph
"customer" does not include an Operator.

13.7 Without prejudice to the generality of paragraph 13.6 the Licensee shall at
all times maintain in operation such a Billing Process as facilitates compliance
by the Licensee with, and is calculated to prevent contravention by it of, that
paragraph.
<PAGE>   38

                                       34


13.8 The Licensee shall not be regarded as being in contravention of its
obligation under paragraph 13.6 except where the failure is in relation to the
Billing Process and the Licensee has failed to take all reasonable steps to
prevent a contravention of that obligation.

13.9 The Licensee shall keep such records as may be necessary or as may be
determined by the Director to be necessary for the purpose of satisfying the
Director that the Billing Process has the characteristics required by paragraph
13.7, provided that nothing in this paragraph shall require the Licensee to
retain any records for more than 2 years from the date on which they came into
being.

13.10 For the purpose of giving the Director an independent quality assurance
from time to time that the Billing Process has the characteristics required by
paragraph 13.7, the Licensee shall, where the Director has prima facie grounds
to believe the Billing Process does not have those characteristics and has so
notified the Licensee, extend its prompt co-operation to the Director and, in
particular, on request by the Director shall;

     (a)  furnish the Director in accordance with the Director's reasonable
          requirements any Information, document (including any facility
          enabling him to read data not held in readable form) or other thing;

     (b)  carry out (or cause to be carried out by such person having such
          special expertise as the Director may specify and to whom the Director
          has raised no reasonable objection) in such manner as the Director may
          specify an examination of the whole or of any part of the Billing
          Process and as soon as practicable after the conclusion of such
          examination furnish to the Director a written report by the Licensee
          or that specified person, as the case may be, of the results of such
          examination;

     (c)  on reasonable notice by him allow at all reasonable times the Director
          and, in the case of any member of his staff, on production of his
          special authority in that behalf, access to any relevant premises,
          plant or equipment of the Licensee;

     (d)  on reasonable notice by him allow at all reasonable times the Director
          and, in the case of any member of his staff, on production of his
          special authority in that behalf, to examine or test the whole or any
          part of the Billing Process including any plant or equipment whether
          or not forming part of the Applicable Systems;

     (e)  for the purpose of paragraphs 13.10(c) and 13.10(d), allow the
          Director to be accompanied by any person as the Director may specify
          and to whom the Licensee has raised no reasonable objection whose
          assistance he might reasonably require for the purpose described at
          the beginning of this paragraph provided that the Director shall have
          given the Licensee notice (save in exceptional circumstances) of at
          least 5 working days of the identity of that person; and
<PAGE>   39

                                       35


     (f)  install and keep installed any equipment (whether or not supplied by
          the Director) for the purpose of verifying;

          (i)  the accuracy and reliability of any equipment or apparatus
               (including any Meter) of the Licensee;

          (ii) in the case of any Meter which is or is required to be Approved
               and is in use in connection with the Applicable Systems,
               compliance with any conditions or other matters which may be
               required as regards such use of that Meter.

13.11 In this Condition:

     (a)  "Approval" and "Approved" mean approval and approved under section 24
          of the Act.

     (b)  "Billing Process" means Metering systems and Billing Systems taken
          together, where "Billing System" means the totality of all apparatus,
          data, procedures and activities which the Licensee employs to
          determine the charges to be sought for Service usage recorded by a
          Metering System based on published or previously negotiated pricing
          structures and to present these charges on customers' bills and
          "Metering System" means the totality of all apparatus, data,
          procedures and activities which the Licensee employs to determine the
          extent of any telecommunication Services provided by means of the
          Applicable Systems;

     (c)  "Information" includes accounts, estimates and returns;

     (d)  "Meter" means any system or apparatus constructed or adapted for use
          in ascertaining the extent of telecommunication Services provided by
          means of the Applicable Systems; and

     (e)  "Service" includes any service provided by any person to whom the
          Licensee is bound to account for any part of the amount charged by the
          Licensee.

NUMBERING ARRANGEMENTS

14.1 This Condition shall only apply where the Applicable Systems are connected
to a telecommunication system not being run under a Licence issued to a
particular person, or where the Licensee has been granted Numbers by the
Director.

14.2 The Licensee shall from the day on which it first provides a switched
telecommunication service or any other telecommunication service in connection
with which the Licensee allocates to users Numbers adopt a Numbering Plan and
shall furnish details thereof to the Director and on request to any other person
having a reasonable interest.

14.3 The Numbering Plan shall describe the method adopted and to be adopted for
allocating and re-allocating in respect of each Network Termination Point such
Number or Numbers as may be necessary for each item of Relevant Apparatus or
each Relevant System that is or is to be connected by means of that Network
Termination Point to any of the switched Applicable Systems.

14.4 The Licensee shall install, maintain or adjust its switched Applicable
Systems so that those Systems convey Messages to Network Termination Points in
respect of which Numbers have been allocated in accordance with the Numbering
Plan.

14.5 The Licensee shall from time to time consult:

     (a)  the Director about the arrangements for the allocation and
          reallocation of Numbers within the Numbering Plan; and

     (b)  in one body approved by the Director for the purpose and
          representative of telecommunications operators and other persons whom
          the Director considers appropriate about any developments of,
          additions to or replacements of, the Numbering Plan.

14.6 The Licensee shall from time to time prepare, taking into account the
consultations mentioned in paragraph 14.5(b), and furnish to the Director
proposals for developing, adding to or replacing the Numbering Plan and changing
the switched Applicable Systems to the extent necessary to secure that:

     (a)  sufficient Numbers are made available, having regard to the
          anticipated growth in demand for telecommunication services, for a
          Number or Numbers to be allocated without undue delay;

     (b)  Numbers include as few digits as practicable and their allocation does
          not confer any undue advantage on the Licensee or undue disadvantage
          on persons running Relevant Systems;
<PAGE>   41

                                       37


     (c)  the cost of changing any of the switched Applicable Systems or any
          Relevant Apparatus or Relevant System in order to accommodate the
          revised Numbering Plan is reasonable; and

     (d)  inconvenience caused by the alteration of the Numbering Plan to the
          Licensee and to persons using Relevant Apparatus or Relevant Systems
          in respect of which Numbers have previously been allocated is
          minimised.

14.7 If the Director determines that the Numbering Plan with any developments,
additions and replacements submitted in accordance with paragraph 14.6 is
sufficient to provide compatibility with the numbering arrangements applied or
to be applied by telecommunications operators and to meet the objectives
specified in paragraph 14.6 the Licensee shall adopt the Numbering Plan but, if
the Director determines that it is not compatible with numbering arrangements
applied or to be applied by another public telecommunications operator or will
not be sufficient to achieve the objectives specified in paragraph 14.6, then
the Licensee shall adopt the Numbering Plan with such developments, additions or
replacements as the Director may determine are best calculated to secure the
objectives specified in paragraph 14.6.

14.8 Before making a determination under paragraph 14.7 the Director shall take
account of:

     (a)  the state of technical development of the Applicable Systems and the
          Licensee's plans for their commercial development;

     (b)  the balance of advantage between:

          (i)  making developments of, additions to or replacements of numbering
               arrangements applied or to be applied, or making changes to
               systems run, by others; and

          (ii) making any requirement of the Licensee;

     (c)  the cost to the Licensee and to those to whom the Licensee provides
          telecommunication services arising from any determination;

     (d)  any obligations and recommendations of the International
          Telecommunication Union which apply to Her Majesty's Government and
          are accepted by it and any other standard to which the Director
          consents for the purpose from time to time; and

     (e)  the views of the Licensee and such other persons (including operators
          of telecommunication systems, those to whom telecommunication services
          are provided or telecommunication apparatus is supplied and producers
          of telecommunication apparatus) as appear to the Director to have an
          interest in the matter.

                                       38


14.9 Where the Licensee has adopted a Numbering Plan in accordance with 
paragraph 14.7, or the Director has made a determination under that paragraph
(by virtue of which the Licensee shall adopt the Numbering Plan), the Numbering
Plan so adopted shall be the Licensee's Numbering Plan until the Licensee adopts
a Numbering Plan pursuant to the following provisions of this Condition. The
Numbering Plan referred to in the following provisions of this Condition is the
Numbering Plan adopted pursuant to those provisions.

14.10 The Director may determine a Specified Numbering Scheme (the "Scheme") in
accordance with the National Numbering Conventions (the "Conventions") published
in accordance with paragraph 14.14 and he will allocate Numbers from this Scheme
to the Licensee in accordance with the Conventions. The initial allocation of
Numbers to the Licensee shall be of those Numbers to which the Numbering Plan
referred to in paragraph 14.3 relates and of any other Numbers to which any
other Numbering Plan in force immediately before such allocation relates,
provided that, at such time of initial allocation, those Numbers are currently
in use by the Licensee, and where not so in use, the Director shall have due
regard to the Licensee's plans and future requirements for its use and
allocation of additional Numbers. The Director shall, at the request from time
to time of the Licensee, allocate to it:

     (a)  such quantity of additional Numbers as it may require; and

     (b)  in accordance with the Conventions, such specific Numbers as it may
          request and which the Director is satisfied are not required for other
          purposes.

14.11 The Licensee shall adopt a Numbering Plan for such Numbers as the Director
may allocate to it from time to time in accordance with the Conventions. It
shall within three month's of being notified of such allocation furnish details
of the Numbering Plan to the Director, and keep him informed of material changes
to the Numbering Plan as they occur. The Licensee shall also furnish details of
the Numbering Plan together with any material changes to that Numbering Plan on
request to any other person having a reasonable interest. Except where the
Director agrees otherwise, the Numbering Plan shall be consistent with the
Conventions published in accordance with paragraph 14.14. If the Numbering Plan
is not consistent with those Conventions, the Director may direct the Licensee
to adopt and furnish him with a new Numbering Plan or to take such other
reasonable remedial action which does not cause undue inconvenience to the
Licensee's customers, as may be necessary to ensure consistency.

14.12 The Licensee shall install, maintain and adjust its switched Applicable
Systems so that those Systems route Messages and otherwise operate in accordance
with the Numbering Plan. The Licensee shall not use Numbers other than those
allocated to it from the Scheme except:

     (a)  with the written consent of the Director; or

     (b)  where the use of those Numbers is the subject of an agreement to which

                                       39


14.13 (a) The Licensee shall provide to the Director, on request, such
          information about its operations under its Numbering Plan as he may
          reasonably require to administer the Scheme and in particular on:

          (i)  the percentages of Numbers in significant ranges which have
               already been allocated to end-users or which for other reasons
               are unavailable for further allocation;

          (ii) any allocation of blocks of Numbers to any person for purposes
               other than end use;

          (iii) Numbers whose use has been transferred at an end-user's request
                to another Operator; and

          (iv) the Licensee's current forecasts of all of the above matters.

     (b)  The Licensee shall not be required to provide information about
          individual end-user customers.

     (c)  In making any such request the Director shall ensure that no undue
          burden is imposed on the Licensee in procuring and furnishing such
          information and, in particular, that the Licensee is not required to
          procure or furnish information which would not normally be available
          to it, unless the Director is satisfied that such information is
          essential to the administration of the Scheme.

14.14 (a) The Conventions referred to in this Condition will be a set of
          principles and rules published from time to time by the Director after
          consultation with interested parties who are members of the
          Telecommunications Numbering and Addressing Body and, if deemed
          appropriate, with end-users.

     (b)  In consulting the said interested parties, the Director shall afford a
          reasonable period, not being less than 28 days, for them to make
          representations, and he shall take the said representations into
          account when publishing the Conventions. The Conventions shall govern
          the specification and application of the Scheme and the Numbering Plan
          of the Licensee and may also include such other matters relating to
          the use and management of Numbers as (but not limited to):

          (i)  criteria and procedures relating to the application for,
               allocation of and withdrawal of Numbers;

          (ii) dialling plans;

          (iii) access codes;

          (iv) prefixes;
<PAGE>   44

                                       40


          (v)  standard ways of recording Numbers for convenience or ease of
               use, such as the grouping of digits in Numbers of particular
               lengths; and

          (vi) methods of enabling end-users to understand the meaning implicit
               in Numbers or other dialled digits, and in particular the rate at
               which a call to a particular Number will be chargeable.

     (c)  The Director may from time to time amend or withdraw a Convention
          already published, after consultation with interested parties who are
          members of the Telecommunications Numbering and Addressing Body. The
          Licensee shall not be required to comply with any such amendment or
          withdrawal unless the Licensee has been given a reasonable period of
          notice, such notice not being less than three months. Numbers
          allocated to the Licensee may only be withdrawn after similar
          consultation and notice, and the Director shall consult end-users
          affected by such withdrawal. Subject to overriding national interests,
          or where there is no alternative solution available, the power to
          withdraw Numbers shall not apply to any Numbers which the Director has
          approved from time to time as part of a specific service of the
          Licensee, which, as a result of investment by the Licensee, has a
          recognised identity and quality associated with that particular
          Number and which the Licensee is using and plans to continue to use.

14.15 In deciding on the details of and any subsequent changes to the Scheme and
the Conventions, and when making or changing Number allocations within the
Scheme or making determinations under this Condition, the Director shall ensure
that the Scheme complies with the Conventions and shall have regard to:

     (a)  the need for sufficient Numbers to be made available, having regard to
          the anticipated growth in demand for telecommunication services,
          together with the need for good husbandry of that supply at any time;

     (b)  the need to ensure Compatibility with the the Numbering Plans adopted
          or to be adopted by telecommunications operators; 

     (c)  the convenience and preferences of end-users;

     (d)  the requirements of effective competition;

     (e)  the practicability of implementing the Conventions in licensed systems
          by the date when the Conventions are intended to apply;

     (f)  any costs or inconvenience imposed on the Licensee, other
          telecommunications operators, end-users and other interested parties
          (including those overseas);

     (g)  any relevant international agreements, recommendations or standards;

     (h)  the views of the Licensee and other interested parties; and
<PAGE>   45

                                       41


     (i)  any other matters he regards as relevant.

14.16 The Licensee shall not, unless the Director consents otherwise, charge any
person for a Number which is allocated to him (other than a coveted Number
allocated to a person who is not a public telecommunications operator at the
request of such a person), but nothing in this Condition shall preclude the
Licensee from recovering from the operator of a Relevant System the reasonable
costs associated with allocating Numbers to and routing calls to that System;
save that in the case of any dispute or difference as to those costs the
Director may determine them and the Licensee shall not be obliged so to allocate
Numbers and route calls unless such operator agrees to bear the costs so
determined.

14.17 For the purposes of this Condition, "Telecommunications Numbering and
Addressing Body" means a body approved by the Director as representative of the
Licensee and other persons whom the Director considers it appropriate to include
in consultations about the content of the Conventions and the Scheme.

14.18 For the avoidance of doubt, it is hereby declared that this Condition
applies notwithstanding any arrangements for numbering arising by virtue of any
agreement to which Condition 5 applies. But nothing in this paragraph shall
affect the operation of any such agreements entered into before the coming into
force of this Licence.

14.19 The Numbers to which this Condition applies are Numbers:

     (a)  of a class described in CCITT Recommendation E.160, E.163, E.164,
          E.165, E.166 or F.69 or their functional successors; or

     (b)  which are of a class described in CCITT Recommendation X.121 and which
          include any Data Network Identification Code which has been:

          (i)  allocated before 14 November 1986 in accordance with a Numbering
               Plan furnished to the Director; or

          (ii) specified by the Director for the purposes of this Licence and
               described in a list kept for that purpose by the Director and
               made available by him for inspection to the general public.

ARRANGEMENTS FOR PROPORTIONATE RETURN

15.1 This Condition shall apply in respect of the conveyance of Messages to or
from each country and territory in the world other than as specified from time
to time by the Secretary of State.

15.2 Except insofar as the Director may otherwise consent in writing, the
Licensee shall ensure (using the most up-to-date information available) that
over each quarterly period for each Accounting Rate Service the First Ratio
shall be no greater than the Second Ratio.

15.3 Where it appears to the Director that in respect of any country or
territory the obligation imposed by paragraph 15.2 is being breached, he may
make a determination to that effect and the Licensee shall take such steps as
the Director may direct for the purpose of remedying the situation. In
particular, and without prejudice to the generality of the foregoing, any such
direction may require the Licensee to cease to convey any Messages to that
country or territory.

15.4 In this Condition:

     "First Ratio"                    means the volume of Messages comprised in
                                      each Accounting Rate Service which are
                                      conveyed by the Applicable Systems and are
                                      delivered to the United Kingdom divided by
                                      the volume of all Messages comprised in
                                      each Accounting Rate Service which are
                                      delivered to the United Kingdom; and

     "Second Ratio"                   means the volume of all Messages comprised
                                      in each Accounting Rate Service which are
                                      conveyed by the Applicable Systems and are
                                      sent from the United Kingdom divided by
                                      the volume of all Messages comprised in
                                      each Accounting Rate Service which are
                                      sent from the United Kingdom.

ARRANGEMENTS FOR ACCOUNTING IN RESPECT OF INTERNATIONAL CONVEYANCE SERVICES

16.1 This Condition shall apply in respect of the conveyance of Messages to or
from each country and territory in the world other than as specified from time
to time by the Secretary of State.

16.2 The Licensee shall inform the Director of accounting rates and methods of
settlement and division of the accounting rates agreed for all Accounting Rate
Services, before those rates are put into operation.

16.3 As soon as practicably possible after making any correspondent arrangement
with an overseas operator, the Licensee shall inform the Director and all other
holders of a Licence authorising the provision of International Conveyance
Services in the United Kingdom and who are operating, or who have announced an
intention to operate on that particular route, of the terms of that arrangement,
in particular and without prejudice to the generality of the foregoing,
including details of any changes to existing accounting rates or methods of
settlement or division of the accounting rates.

16.4 Where it appears to the Director that any accounting rate or methods of
settlement or division of the accounting rates agreed by the Licensee in respect
of any Accounting Rate Service has or is likely to have an effect to the
detriment of providers and users of International Conveyance Services in the
United Kingdom, he may make a determination to that effect and the Licensee
shall take such steps as the Director may direct for the purpose of remedying
the situation. In particular, and without prejudice to the generality of the
foregoing, any such direction may require the Licensee to cease to convey any
Messages to that country or territory.

PROHIBITION OF EXCLUSIVE DEALING IN INTERNATIONAL SERVICES

17.1 The Licensee shall not enter into any agreement or arrangement with any
person running an Authorised Overseas System on terms or conditions which
unfairly preclude or restrict the provision by another public telecommunications
operator of International Conveyance Services.

17.2 The Licensee shall not unreasonably exclude any other public
telecommunications operator who is authorised by a licence to connect his system
to another telecommunication system situated outside the United Kingdom so as to
convey Messages to that other system from a reasonable opportunity to
participate in any international arrangements into which it proposes to enter
after the date on which this Licence enters into force for the installation and
operation of any submarine cable linking any of the Applicable Systems to any
telecommunication system outside the United Kingdom.

NOTIFICATION OF CHANGES IN SHAREHOLDINGS

18.1 The Licensee shall notify the Secretary of State if an undertaking becomes
a Parent Undertaking in relation to the Licensee.

18.2 Subject to paragraph 18.3, the Licensee shall notify the Secretary of State
of:

      (a)   any change in the proportion of the Shares held in a Relevant
            Company by any person;

      (b)   the acquisition of any Shares in a Relevant Company by a person not
            already holding any such Shares, and the proportion of any such
            Shares held by that person immediately after that acquisition.

18.3 The Licensee shall be obliged to notify the Secretary of State of any
acquisition of Shares or change in the Shareholding of a Relevant Company by any
person only if, by reason of that acquisition or change, the total number of
Shares in that Relevant Company held by that person otherwise than as trustee or
nominee for another person together with any Shares held by any nominee or
trustee for that person immediately after that change or acquisition:

      (a)   exceeds 15 per cent of the total number of Shares in that company
            (where it did not exceed 15 per cent prior to that change or
            acquisition);

      (b)   exceeds 30 per cent of the total number of Shares in that company
            (where it did not exceed 30 per cent prior to that change or
            acquisition); or

      (c)   exceeds 50 per cent of the total number of Shares in that company
            (where it did not exceed 50 per cent prior to that change or

the Secretary of State as soon as practicable all information in respect of that
acquisition or that change as is entered on or received for entry on the
register required to be maintained by that Relevant Company under section 211 of
the Companies Act 1985.

18.4 In any case referred to in paragraph 18.1 or 18.2, notification shall be

LICENSEE'S GROUP

19.1 Without prejudice to the Licensee's obligations under these Conditions in
respect, in particular, of anything done on its behalf, where:

      (a)   the Director determines either:

            (i)   that a member of the Licensee's Group has done something which
                  would, if it had been done by the Licensee, be prohibited or
                  not be authorised under these Conditions; or

            (ii)  that a member of the Licensee's Group has done something which
                  would, if it had been done by the Licensee, require the
                  Licensee to take or refrain from taking a particular action
                  under these Conditions and that neither the Licensee nor the
                  member has met that further requirement; and

      (b)   the Director is not satisfied that the Licensee has taken all
            reasonable steps to prevent any member acting in that way,

then the Director may direct the Licensee to take such steps as the Director
deems appropriate for the purpose of remedying the matter, including refraining
from carrying on with that member such commercial activities connected with
telecommunications as the Director may determine.

19.2 Where these Conditions apply in respect of the Applicable Systems they do
not apply in respect of any other telecommunication system, whether run by the
Licensee or another.

19.3 Where any person becomes a member of the Licensee's Group then the Licensee
shall not be subject to paragraph 19.1 before that is reasonably practicable but
shall be so not later than one year after that person becomes such a member or
such later date as the Director may determine.

19.4 This Condition shall not apply to any particular member of the Licensee's
Group if and to the extent that the Director so determines.

PAYMENT OF FEES

20.1 The Licensee shall pay the following amounts to the Secretary of State at
the times stated:

      (a)   on the grant of this Licence the sum of (pounds)7,000;

      (b)   on 1 April 1997 a renewal fee of (at the option of the Director)
            either(pounds)8,000 or such amount which shall represent a fair
            proportion, to be determined each year by the Director according to
            a method that has been disclosed to the Licensee, of the estimated
            costs to be incurred in that fiscal year by the Director in the
            regulation and enforcement of telecommunication licences and in the
            exercise of his other functions under the Act. The first renewal fee
            shall be reduced by the proportion which the period from the date of
            granting of this Licence until the next following 1 April 1997 bears
            to the period of one year; and

      (c)   when the Director so determines, a special fee which shall represent
            a fair proportion, to be determined by the Director according to a
            method that has been disclosed to the Licensee of the amount, if
            any, by which the aggregate of:

            (i)   the costs estimated to have been already incurred in that
                  fiscal year by the Director in the regulation and enforcement
                  of telecommunication licences and in the exercise of his other
                  functions under the Act;

            (ii)  the costs estimated to have been already incurred in that
                  fiscal year by the Monopolies and Mergers Commission following
                  licence modification references under section 13 of the Act;
                  and

            (iii) the estimated costs to be incurred in the remainder of that
                  fiscal year:

                  (A)   by the Director in the regulation and enforcement of
                        telecommunication licences and in the exercise of his
                        other functions under the Act; and

                  (B)   by the Monopolies and Mergers Commission following
                        licence modification references under section 13 of the
                        Act,

            exceeds the renewal fee for that year,

save always that the aggregate of the renewal fee and the special fee for any
fiscal year shall not exceed 0.08% of the annual turnover of the Systems
Business in the financial year before the last complete financial year of the
Licensee before the renewal fee is payable, or (pounds)35,000 (adjusted in the
manner described in paragraph 20.1(b), whichever is the greater (the "normal
<PAGE>   52

                                       48


aggregate fee"), unless the Director determines that the costs incurred in any
fiscal year by him and the Monopolies and Mergers Commission in respect of the
Licensee's activities exceeds the normal aggregate fee, in which case the
aggregate of the renewal fee and the special fee for the following year shall be
such amount as the Director determines is sufficient to take account of that
excess as well as of the other costs to be incurred as mentioned in this
paragraph.

REQUIREMENT TO FURNISH INFORMATION TO THE DIRECTOR

21.1 Without prejudice to Condition 22, the Licensee shall furnish to the
Director, in such manner and at such times as the Director may reasonably
request, such documents, accounts, estimates, returns or other information and
procure and furnish to him such reports as he may reasonably require for the
purpose of exercising the functions assigned or transferred to him by or under
Parts II and III of the Act.

21.2 In making any such request the Director shall ensure that no undue burden
is imposed on the Licensee in procuring and furnishing such information and, in
particular, that the Licensee is not required to procure or furnish a report
which would not normally be available to it unless the Director considers the
particular report essential to enable him to exercise his functions.

REQUIREMENT TO SUBMIT ACCOUNTS TO THE DIRECTOR

22.1 The Licensee shall maintain such accounting records dealing separately with
its International Business carried on in the United Kingdom as will enable it to
show separately and explain, in response to any request from the Director under
paragraph 22.4, all the transactions to which paragraph 22.2 refers.

22.2 This paragraph refers to:

      (a)   all transactions between each Relevant International Function run as
            part of the Licensee's International Business; and

      (b)   all transactions between the Licensee's International Business and:

            (i)   any other business carried on by the Licensee whether in the

            (ii)  the business of any Associated Person whether in the United
                  Kingdom or elsewhere.

22.3 The Licensee shall update the accounting records referred to in paragraph
22.1 no less frequently than monthly and those records shall include in
particular the costs (including capital costs), revenue and a reasonable
assessment of assets employed in and liabilities attributable to the
International Business and, separately, the amount of any material item of
revenue, cost, asset or liability which has been either:

      (a)   charged from or to any other business of the Licensee or Associated
            Person together with a description of the basis of the value on
            which the charge was made; or

      (b)   determined by apportionment or attribution from an activity common
            to the business and any other business of the Licensee or any
            Associated Person and, if not otherwise disclosed, the basis of the
            apportionment or attribution.

22.4 The Director may at any time request from the Licensee copies of any of the
accounting records and detailed attribution policies and procedures which the
Licensee is obliged to maintain by this Condition, covering any period between:

      (a)   the date on which the Licensee first carried on any International
            Business in the United Kingdom or, if later, the date of this
            Licence; and

      (b)   the date on which such records were, or should have been, last
            updated in accordance with paragraph 22.3.
<PAGE>   55

The Licensee shall provide any such records requested by the Director within
28 days of receiving such a request in writing.

22.5        (1) Accounting records submitted to the Director shall, so far as
            reasonably practicable, be prepared in the formats and in accordance
            with the accounting principles and rules which apply to the annual
            statutory accounts of the Licensee and shall state the attribution
            policies and procedures used and where the Licensee is a body
            corporate incorporated outside the United Kingdom the preparation
            and adoption of those accounts shall comply with the requirements of
            sections 226 and 231 to 234A of the Companies Act 1985 as if that
            body corporate were incorporated in the United Kingdom.

            (ii) The Licensee shall procure in respect of each set of accounting
            records submitted to the Director an audit report which shall
            conform to UK auditing standards by the Auditor in which he shall
            state whether in his opinion the record complies with paragraph 22.1
            and is fairly presented in accordance with the formats, accounting
            principles, rules and requirements referred to in paragraph 22.5(i).

22.6 Where it appears to the Director that to do so would be beneficial to the
promotion or maintenance of competition he may direct the Licensee to publish
the accounting statements submitted to the Director in such way as he sees fit.
In so directing the Licensee the Director shall have regard to the need for
excluding, so far as that is practicable, any matter where publication of that
matter might, in the opinion of the Director, seriously and prejudicially affect
the interests of the Licensee or any Associated Person.

                                                                    Condition 23

EXCEPTIONS AND LIMITATIONS ON OBLIGATIONS IN SCHEDULE 1

23.1 Unless the context otherwise requires and subject to paragraph 23.9, the
Licensee's obligations under these Conditions have effect subject to the
following exceptions and limitations. 

23.2 The Licensee is not obliged to do anything which is not practicable.

23.3 The Licensee shall not be held to have failed to comply with an obligation
imposed upon it by or under these Conditions if and to the extent that the
Licensee is prevented from complying with that obligation by any physical,
topographical or other natural obstacle, by the malfunction or failure of any
apparatus or equipment owing to circumstances beyond the control of the
Licensee, by the act of any national authority, local authority or international
organisation or as the result of fire, flood, explosion, accident, emergency,
riot or war. 

23.4 An obligation to provide any telecommunication service shall not apply:

      (a)   where there is no reasonable demand for it; or

      (b)   where provision of the service requested would expose any person
            engaged in its provision to undue risk to health or safety; or

      (c)   where the Licensee is unable to obtain (either because it has not
            been developed or for some other reason beyond the Licensee's
            control) anything necessary to provide a service of the quality or
            standard required by the person who requests the provision of the
            service and, in the event of dispute, the Director's decision as to
            whether anything is necessary shall be final; or

      (d)   where the person to whom the Licensee would otherwise be under an
            obligation to provide any service requests a service at a place in
            which the apparatus necessary to provide that service in that area
            has not been installed (or in which the installation of such
            apparatus has not been completed) or as the case may be such
            apparatus has not been adapted or modified to make it capable of
            providing that service or the trained manpower necessary to provide
            that service is not available in that area, provided that in every
            case where the Licensee declines to provide a service to which this
            paragraph relates it shall have published, or furnished to the
            Director, within 28 days (or such longer period as the Director
            considers reasonable) following receipt by it of the request that
            that service be provided, proposals for:

            (i)   progressively installing, or completing the installation,
                  adaptation or modification of, the apparatus; or

            (ii)  the allocation of the trained manpower,
<PAGE>   57

                                       53


                  necessary for the provision of that service in that area and
                  the Director has not determined that those proposals are
                  unreasonable or are not being effectively carried out; or

      (e)   where the person to whom the Licensee would otherwise be under an
            obligation to provide any service requests a service at a place in
            an area in which the demand or the prospective demand for the
            service is not sufficient, having regard to the revenue likely to be
            earned from the provision of the service in that area, to meet all
            the costs reasonably to be incurred by the Licensee in providing the
            service there, including:

            (i)   the cost of apparatus necessary for the provision of the
                  service there;

            (ii)  the cost of installing, maintaining and operating such
                  apparatus for the purpose of providing the service there; and

            (iii) the cost of the trained manpower necessary to provide the
                  service there; or

      (f)   where in the opinion of the Director it is not reasonably
            practicable in all the circumstances for the Licensee to provide the
            service requested at the time or place demanded.

23.5 The Licensee shall not be obliged to connect or to keep connected to the
Applicable Systems or to permit to be so connected or kept connected any
telecommunication system or telecommunication apparatus or to provide
telecommunication services or to permit the provision of any service if the
person to or for whom that is or is to be done:

      (a)   has not entered or will not enter into a contract for the purpose
            with the Licensee for reasons other than the unreasonable refusal of
            the Licensee to agree terms for the purpose but this paragraph does
            not apply in a case where the Director is satisfied that:

            (i)   the Licensee has not published standard terms and conditions
                  which it proposes to apply for the purpose in question, or the
                  transaction is not fit to be governed by such terms and
                  conditions; and

            (ii)  the Licensee has unreasonably refused to agree terms and
                  conditions for the purpose;

      (b)   is, or in the Director's opinion has given reasonable cause to
            believe that he may become:

            (i)   in breach of a contract with the Licensee for the provision of
                  telecommunication services by the Licensee; or
<PAGE>   58

                                       54


            (ii)  in default in regard to any debt or liability owed to the
                  Licensee in respect of any such contract;

      (c)   is using, or permitting the use of, apparatus so connected or kept
            connected for any illegal purpose or has done so in the past and is
            likely to do so again; or

      (d)   has obtained, or attempted to obtain, any telecommunication service
            from the Licensee by corrupt, dishonest or illegal means at any
            time.

23.6 Nothing in these Conditions shall prevent the Licensee from withdrawing
from, or declining to provide to, any person any telecommunication service which
the Licensee has notified the Director that it is providing in a limited area,
or to a limited class of customers, for the purpose of evaluating the technical
feasibility of, or the commercial prospects for, that service.

23.7 Nothing in these Conditions shall require the Licensee to provide any
telecommunication service, or to provide any telecommunication service of any
particular class or description, if it provides instead a service, or a service
of a class or description, which satisfies the purposes of that requirement at
least to the same extent.

23.8 This Condition shall apply without prejudice to any limitation or
qualification of the requirements imposed by or under any other Condition.

23.9 This Condition does not apply to Condition 5, 8 or 10 and:

      (a)   only paragraphs 23.1, 23.2, 23.3 and 23.8 apply to Conditions 7,
            13.2, 13.3, 19, 20 and 21;

      (b)   only paragraphs 23.1, 23.5(a) and 23.8 apply to Condition 4.2;

            14;

      (d)   only paragraphs 23.1, 23.2, 23.3, 23.4(b), 23.5(a) and 23.8 apply to
            Condition 3; and

      (e)   only paragraphs 23.1, 23.2, 23.3, 23.4, 23.6 and 23.8 apply to

                  that he is minded to revoke this Licence on the grounds either
                  that:

OVERHEAD LINES

3.1 Without prejudice to Condition 1.1 and subject to paragraph 3.4, the
Licensee shall take steps to ensure that, wherever practicable, taking into
account the need to provide telecommunication services at the lowest reasonable
cost, new Lines (other than overhead Service Lines flown from poles) installed
after the date on which this Licence enters into force are installed
underground.

3.2 The Licensee shall consider carefully a request by any person that any of
its existing Lines be resited underground. If the Licensee is satisfied that the
person making the request will pay the costs of placing any such Line
underground, the Licensee shall, wherever it is reasonable and practicable, so
place the Line. In other cases, except where the request is frivolous, the
Licensee shall be obliged within 28 days of receiving it, to give notice in
writing of its decision whether or not to accede to the request to the person
making the request giving, where it decides to refuse, reasons.

3.3 Where telecommunication services are to be provided to a person occupying or
proposing to occupy a new development the Licensee shall consider in conjunction
with those responsible for the development and any other statutory undertaker
providing or proposing to provide a service to persons occupying that
development whether Lines can be installed underground on a shared cost basis.

3.4 Nothing in this Condition or Condition 4 shall prevent the Licensee from
installing new overhead Telecommunication Apparatus where that Apparatus is
supported on poles or pylons belonging to a Relevant Owner and used by that
Relevant Owner for the transport of electricity at a nominal voltage of at least
6,000 volts.

employees and agents) that:

      (a)   where apparatus is to be installed underground in a Street or, in
            Scotland, a Road, the normal practice will be to place it in the
            verge or footway (or the prospective verge or footway), if any,
            rather than the carriageway;

      (b)   provision is made for any new Ducts installed after the date on
            which this Licence comes into effect to, contain sufficient spare
            capacity to meet demand which is reasonably foreseeable by the
            Licensee for telecommunication services provided by it;

      (c)   where apparatus is to be installed underground in a Street or, in
            Scotland, a Road the Street Authority or, in Scotland, the Road

            position in that Street or Road, as the case may be;

      (d)   effective liaison is maintained with Highway Authorities or, in
            Scotland, Road Authorities with a view to ensuring that works which
            entail breaking up the surface of a Maintainable Highway or, in
            Scotland, a Public Road are carried out in advance of scheduled
            resurfacing works or together with other schemes affecting the
            highway;

      (e)   effective liaison is maintained with Relevant Undertakers with a
            view to avoiding the disruption of the services provided by those
            persons;

      (f)   effective liaison is maintained, with the Street Authority or, in
            Scotland, the Road Works Authority in order to ensure that

            Apparatus, whether such damage occurs before or after the Relevant
            Event;

      (c)   any other costs or expenses reasonably incurred by any Appropriate
            Authority or other responsible authority after the Relevant Event
            occurs in removing any Telecommunication Apparatus:

            (i)   which is installed under, over, along or across a Street;

            (ii)  which is not, or is no longer, used for the purposes of any

                  reasonable likelihood that it will be so used; and

            (iii) the removal of which is desirable having regard to any harm it
                  may cause to other persons or property, or to the visual

            (ii)  (pounds)1,000,000,

            whichever is the lesser, or such greater amount as the Director may
            direct; and

      (b)   an amount which, having regard to any works begun by the Licensee
            before the beginning of the period in question, is sufficient to
            meet any liabilities of the kinds described in paragraph 13.2(a)
            which may arise.

13.4 The Licensee shall:

      (a)   within three months of this Licence coming into force; and

      (b)   once a year thereafter,

inform the Director of the steps taken to implement this Condition.

13.5 Where:

      (a)   the Licensee has failed to inform the Director in accordance with
            paragraph 13.4; or

      (b)   the Director is not satisfied that the arrangements made by the
            Licensee are adequate to secure that sufficient funds are available
            after the Relevant Event occurs for meeting the liabilities
            described in paragraph 13.1

the Director may direct the Licensee to take such steps as the Director
considers appropriate for the purpose of securing that such sufficient funds are
available and the Licensee shall comply with any such direction.
