1. FINANCIAL PRESENTATION

   The financial statements of Hermes Europe Railtel B.V. (the "Company")
   included herein are unaudited and have been prepared in accordance with
   generally accepted accounting principles for interim financial reporting and
   Securities and Exchange Commission regulations.  Certain information and
   footnote disclosures normally included in financial statements prepared in
   accordance with generally accepted accounting principles have been condensed
   or omitted pursuant to such rules and regulations.  Material intercompany
   affiliate account transactions have been eliminated; however, other
   adjustments may have been required had an audit been performed.  In the
   opinion of management, the financial statements reflect all adjustments of a
   normal and recurring nature necessary to present fairly the Company's
   financial position, results of operations and cash flows for the interim
   periods.  These financial statements should be read in conjunction with the
   Company's 1997 audited consolidated financial statements and the notes
   related thereto.  The results of operations for the three months ended March
   31, 1998 may not be indicative of the operating results for the full year.
        
   The Company is developing and operating the initial segments of a
   pan-European high capacity fiber optic network that is designed to
   interconnect a majority of the largest Western and Central European cities
   and to transport international voice, data and multimedia/image traffic for
   other carriers throughout Western and Central Europe.  

   The Company'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 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.
        
2. POLICIES AND PROCEDURES

   On January 1, 1998, the Company adopted Statement of Financial Accounting
   Standards ("SFAS") No. 130, "Reporting Comprehensive Income," which
   establishes standards for reporting and display of comprehensive income and
   its components in a full set of general purpose financial statements. 
   Comprehensive income is defined as the change in equity of a business
   enterprise during a period from nonowner sources.  Comprehensive loss was
   $5.9 million and $12.7 million for the three months ended March 31, 1997 and
   1998, respectively, and was comprised of net loss of $4.2 million and $11.3
   million and foreign currency translation adjustments of $0.9 million and $1.4
   million for the three months ended March 31, 1997 and 1998, respectively.  
        
   During 1997, the Company adopted SFAS No. 128, "Earnings Per Share," which
   requires the Company to present basic and fully diluted earnings per share
   for all periods presented.  The Company's net loss per share calculation
   (basic and fully diluted) is based upon the weighted average common shares
   issued.  There are no reconciling items in the numerator or denominator of
   the Company's net loss per share calculation.  Employee stock options have
   been excluded from the net loss per share calculation because their effect
   would be anti-dilutive.  
        
   Certain reclassifications have been made to the March 1997 condensed,
   consolidated financial statements in order to conform to the 1998
   presentation.

3. CAPITAL LEASE OBLIGATIONS

   During the three months ended March 31, 1998, HER entered into contractual
   commitments to lease fiber pairs, including facilities and maintenance and
   utilizing the partial routes for laying fiber optic cable.  Based on the
   contract provisions, these commitments are currently estimated to aggregate
   approximately $26.9 million.  The commitments have expected lease terms of
   ten to twenty-one years with options for renewal rights of one and one-half
   to five additional years.  Subsequent to March 31, 1998, HER entered into
   additional contractual commitments to lease fiber pairs that are currently
   estimated to aggregate approximately $22.5 million.  These commitments have
   expected lease terms of eight and one-half to eighteen years with certain of
   the leases having options for renewal rights of five additional years.

Item 2.  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 March 31, 1998 and 1997 and for the three months
ended March 31, 1998 and 1997 and of certain factors that management believes
are likely to affect the Company's prospective financial condition. The
following discussion should be read in conjunction with the Company's Condensed,
Consolidated Financial Statements and the notes related thereto.

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


OVERVIEW

         The Company is developing and operating the initial segments of a
pan-European high capacity fiber optic network and has been delivering services
to customers since November 1996 when the Brussels-Amsterdam route came into
operation. The cities of London and Paris came into commercial operation during
the last quarter of 1997 and in the first quarter of 1998, Frankfurt was added
to the network. 

RESULTS OF OPERATIONS

         Revenue. The Company's consolidated revenues for the three months ended
March 31, 1998 were $4.7 million compared to $0.2 million for the same period in
1997. Revenue for the three months ended March 31, 1998 was generated from the
Brussels-Amsterdam-London-Paris routes whereas revenue for the three months
ended March 31, 1997 was only from the Brussels-Amsterdam route. 

         Cost of Revenue. The Company's cost of revenue for the three months
ended March 31, 1998 and 1997 was $6.1 million and $1.8 million, respectively.
The increase in cost of revenue for the three months ended March 31, 1998 as
compared to the same period in 1997 was associated with the costs related to
operating and maintaining the network, local access costs and the depreciation
of the network.

         Gross Margin. The Company had negative gross margins of $1.4 million
and $1.6 million for the three months ended March 31, 1998 and 1997,
respectively. The growth in revenues for the three months ended March 31, 1998
as compared to 1997 was more than offset by its increase of cost of revenues
during the same period.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the three months ended 1998 were $4.6 million as
compared to $2.7 million for the same period in 1997. The increase in selling,
general and administrative expenses is reflective of the growth of the Company's
business operations and support personnel.  At March 31, 1998 the Company
employed 153 people as compared to 107 people at March 31, 1997.

         Interest. Interest expense for the three months ended March 31, 1998
was $7.4 million as compared to $0.2 million for the same period in 1997. The
increase was primarily attributable to the interest and related costs associated
with the issuance in August 1997 of $265 million aggregate principal amount of
11.5% Senior Notes due 2007 (The "Senior Notes").

         Interest income for the three months ended March 31, 1998 was $3.3
million. Interest income was minimal for the same period in 1997. The increase
in interest income was the result of investing the excess cash generated from
the issuance of the Senior Notes in various highly liquid investments. 

<PAGE>   10
 Global TeleSystems Group, Inc. ("GTS"), a Delaware corporation that provides a
broad range of telecommunications services to businesses, other
telecommunications service providers and consumers in Russia, The Commonwealth
of Independent States and Central Europe, owns 89.4% of the Company. In May
1998, GTS filed registration statements with the Securities and Exchange
Commission to offer for sale concurrently $300 million of GTS's common stock and
$400 million aggregate principal amount of GTS's convertible senior debentures.
GTS indicated in such filings that the net proceeds of such offerings would be
applied primarily to the implementation of its plans to offer, through one or
more subsidiaries, facilities-based telecommunications products and services
primarily to business and other high-usage customers in certain metropolitan
markets throughout Europe ("GTS's European Services Strategy"). Many of GTS's
planned service offerings will compete with the services offered by customers
that HER targets as an independent carrier's carrier. To the extent that GTS's
other subsidiaries offering the new services discussed above contract with HER
for capacity, GTS expects that such arrangements will be entered into on an
arm's length basis. However, GTS's European Services Strategy could affect the
perception of HER as an independent operator and could negatively impact HER's
ability to attract and retain customers.


LIQUIDITY AND CAPITAL RESOURCES

         The primary sources of Company funding through March 31, 1998 have been
cash equity contributions of $103.2 million in 1997 and net proceeds of $251.3
million from the issuance of the Senior Notes.

         Development of the Company's fiber optic network is capital intensive.
The build-out of the network is expected to require approximately $290.0 million
of capital expenditures. Through March 31, 1998 approximately $64.7 million has
been spent on network capital expenditures. An additional $173.1 million has
been capitalized in connection with long-term fiber lease arrangements. In
August 1997, HER completed the issuance of $265.0 million in gross proceeds of
11.5% Senior Notes, due in August 2007. The 11.5% Senior Notes are general
unsecured obligations of HER. The Company believes that the net proceeds of the
Senior Notes, combined with HER's projected internally generated funds, should
be sufficient to fund HER's expected capital expenditures. However, the actual
amount and timing of HER's future requirements may differ materially from
management's estimates. Any failure to obtain necessary financing may require
the Company to delay or abandon its plans for deploying the remainder of the
network and would jeopardize the viability of the Company.

         The Company had a positive working capital of $180.7 million at 
March 31, 1998 compared to a negative working capital of $2.5 million at March
31, 1997. The Company had cash and cash equivalents of $182.8 million and $2.2
million as at March 31, 1998 and 1997 respectively. The Company had $43.6
million and $3.6 million of restricted cash at March 31, 1998 and 1997,
respectively. The restricted cash at March 31, 1998 primarily represents the
Company's obligation to place into escrow the first four scheduled semi-annual
interest payments on the Senior Notes.

         During the three months ended March 31, 1998 and 1997, the Company used
$19.5 million and $5.8 million, respectively, of cash for operating activities.
Investing activities provided cash of $1.7 million and used cash of $4.4 million
for the three months ended March 31, 1998 and 1997, respectively.

         The Company has developed risk management policies that establish
guidelines for managing foreign exchange risk. The Company is currently
evaluating the materiality of foreign exchange exposures in different countries
and the financial instruments available to mitigate this exposure. The Company
is designing reporting processes to monitor the potential exposure on an ongoing
basis and expects to implement this process by the end of 1998. In April 1998,
the Company consummated a transaction to hedge the foreign exchange exposure
resulting from the issuance of the Senior Notes.

YEAR 2000 COMPLIANCE

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