                          VIATEL, INC. AND SUBSIDIARIES

              CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

           (INFORMATION AS OF MARCH 31, 2000 AND FOR THE PERIODS ENDED
                MARCH 31, 2000 AND MARCH 31, 1999 ARE UNAUDITED)





(1)   DESCRIPTION OF BUSINESS

      Viatel, Inc. and subsidiaries (collectively,  the "Company") is a provider
      of   "ALL   DISTANCE"    telecommunications   services   to   individuals,
      corporations,  internet service providers,  applications service providers
      and other communications carriers in Europe and North America. The Company
      is a licensed  provider  of  telecommunications  services  in ten  western
      European  countries,  Canada and the United  States.  The Company owns and
      operates international telecommunications networks and has been building a
      fiber optic network in Western Europe.

(2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      (A)   BASIS OF PRESENTATION

      The  consolidated  financial  statements  as of March 31, 2000 and for the
      three month periods ended March 31, 2000 and 1999, respectively, have been
      prepared  by  the  Company  without  audit,  pursuant  to  the  rules  and
      regulations of the Securities and Exchange  Commission.  In the opinion of
      management,   all  adjustments   (consisting  of  only  normal   recurring
      adjustments)  necessary  for  a  fair  presentation  of  the  consolidated
      financial  position,  results of operations and cash flows for each period
      presented have been made on a consistent  basis.  Certain  information and
      footnote   disclosures   normally   included  in  consolidated   financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed  or  omitted  pursuant  to such rules and
      regulations  although  management believes that the disclosures herein are
      adequate to make the information presented not misleading. It is suggested
      that these financial  statements be read in conjunction with the Company's
      annual consolidated financial statements.  Certain  reclassifications have
      been made to the prior year's condensed  consolidated financial statements
      to conform to the current year's  presentation.  Operating results for the
      three  months  ended March 31, 2000 may not be  indicative  of the results
      that may be expected for the full year.

      (B)  REVENUE AND COST OF SERVICES AND SALES

      The Company records  communication  services revenue as earned at the time
      services  are  provided.  The related  cost of  communication  services is
      reported in the same period.

      Revenue from capacity sales mainly  represents  indefeasible-rights-of-use
      ("IRUs") for sales of portions of the network that qualify for  sales-type
      lease  accounting.   Transactions  that  do  not  meet  the  criteria  for
      sales-type  lease  accounting  are accounted  for as operating  leases and
      revenue is recognized over the term of the lease.

      Cost of capacity sales is determined based upon the ratio of total network
      capacity sold to total estimated network capacity, multiplied by the total
      capitalized costs of the related network.

      In June 1999, the Financial  Accounting  Standards  Board ("FASB")  issued
      Interpretation  No. 43,  "Real Estate  Sales,  an  interpretation  of FASB
      Statement No. 66" ("FIN 43") which is applicable for all contracts entered
      into  after  June 30,  1999.  FIN 43  requires  that a lease  of  property
      improvements or integral  equipment include a provision  allowing title to
      transfer  to the lessee in order for that lease to be  accounted  for as a
      sales-type lease.

      The  Company  recognizes  revenue  in  accordance  with  FIN  43  and  the
      Securities  and Exchange  Commission  Staff  Accounting  Bulletin No. 101,
      "Revenue  Recognition  in  Financial  Statements".   However,   accounting
      practices  and guidance for sales of IRUs is  evolving.  Standard  setting
      bodies are  currently  reviewing a number of issues  related to FIN 43 and
      other related issues are expected to be referred to these bodies.  Changes
      in the accounting treatment for IRUs could affect the way that the Company
      may recognize  revenue and costs  associated  with these capacity sales in
      the future.

      (C)      NEW PRONOUNCEMENT

      In March  2000,  FASB  Interpretation  No. 44 -  "Accounting  for  Certain
      Transactions  Involving  Stock  Compensation,  an  interpretation  of  APB
      Opinion No. 25" ("FIN 44") was issued. FIN 44 clarifies the application of
      APB No. 25  regarding  (a) the  definition  of  EMPLOYEE  for  purposes of
      applying  APB No.  25, (b) the  criteria  for  determining  whether a plan
      qualifies as a  noncompensatory  plan, (c) the  accounting  consequence of
      various  modifications  to the terms of a previously fixed stock option or
      award, and (d) the accounting for an exchange of stock compensation awards
      in a business combination.  FIN 44 does not address the application of the
      fair  value  method  of  Statement  No.  12  (Accounting  for  Stock-Based
      Compensation").  FIN 44 is effective July 1, 2000, but certain conclusions
      in this  interpretation  cover  specific  events that occur  after  either
      December  15,  1998,  or  January  12,  2000.  To  the  extent  that  this
      interpretation  covers events  occurring  during the period after December

      Europe.  For the periods  ended March 31, 2000 and 1999,  $4.2 million and
      $2.3 million, respectively, of interest was capitalized.

      In connection  with the Company's  joint  construction  of the civil works
      associated  with a national  communications  network being  constructed in
      Germany,  the Company was required to obtain a letter of credit in support
      of its obligations.  At March 31, 2000, the total amount outstanding under
      this letter of credit was  approximately  $45.4 million (DM92.5  million).
      This letter of credit is collateralized by cash deposits.

The Company has entered into a credit  facility  with NTFC,  which  provides for
borrowings to fund certain equipment acquisition costs and related expenses. The
facility  provides for an aggregate  commitment of NTFC of $49.0 million.  As of
March 31, 2000, the aggregate  amount due to NTFC was $30.6 million.  All of the
equipment  purchased  with the proceeds of the NTFC facility has been pledged to
NTFC.  The terms of the NTFC  facility  require the Company to maintain  certain
debt service coverage ratios,  certain EBITDA thresholds (both as defined in the
terms of the NTFC  facility),  and minimum cash  balances.  Due to the Company's
acquisition of Destia (as defined  below),  NTFC has the right to require Destia
to  exercise  its  right to repay  all  outstanding  obligtions  under  the NTFC
facility  within 90 days  following  Viatel's  acquisition  of Destia.  NTFC has
extended the date by which it must exercise its right until May 26, 2000. Before
May 26, 2000,  the Company will be required to either (i) obtain a waiver,  (ii)
prepay the  outstanding  amounts  owed at a premium of not more than 102% of the
amount outstanding or (iii) negotiate a new facility. The Company's intent is to
renegotiate  a new  facility  with NTFC and, as such,  the Company  continues to
record the NTFC borrowings as a long term liability.

(8)   SEGMENT AND GEOGRAPHIC DATA

      While the Company's management monitors the revenue streams of the various
      products and  geographic  locations,  operations are managed and financial
      performance  is evaluated  based on the  delivery of multiple,  integrated
      services to customers over a single network.  As a result,  there are many
      shared  expenses  generated by the various  revenue streams and management
      believes that any allocation of the expenses  incurred to multiple revenue
      streams  or  geographic  locations  would be  impractical  and  arbitrary.
      Management does not currently make such allocations internally.

      The  Company  groups its  products  and  services  by  retail,  wholesale,
      advanced services,  and capacity. The information below summarizes revenue
      by type for the three months ended March 31 (in thousands):

(9)   ACQUISITIONS

      DESTIA COMMUNICATIONS, INC.

      On December 8, 1999,  the Company  acquired  Destia  Communications,  Inc.
      ("Destia")   through  a  merger  of  Destia  with  one  of  the  Company's
      subsidiaries.  Destia  is a  facilities-based  provider  of  domestic  and
      international  long  distance  telecommunications  services  in Europe and
      North  America.  Its  customer  base  consists of  residential  customers,
      commercial customers, ethnic groups and other telecommunications carriers.
      Destia offers a variety of retail telecommunications  services,  including
      international  and domestic long  distance,  Internet  access and wireless
      services.  On  February  13,  2000,  Destia's  name was  changed to Viatel
      Communications, Inc.

      In  connection  with the  Company's  integration  plan, as of December 31,
      1999, the Company recorded accruals related to the closing and termination
      of Destia  facilities  and lease and other  contract costs of $9.2 million
      and  employee  termination  costs  relating  to Destia  employees  of $2.2
      million.  Payments  made  during the three  months  ended  March 31,  2000
      against these accruals totaled $5.1 million, of which $4.6 million related
      to lease and other contract cancellation costs and $0.5 million related to
      employee termination costs.

      AT&T COMMUNICATIONS (UK) LIMITED

      On  February  29,  2000,  the  Company  acquired  all  of the  issued  and
      outstanding  share  capital  of AT&T  Corporation's  UK  subsidiary,  AT&T
      Communications  (UK) Limited ("AT&T UK"). As a result of the  transaction,
      AT&T UK became a  wholly-owned  subsidiary  of the  Company.  AT&T UK is a
      provider  of voice  and  data  solutions  to  primarily  enterprise  level
      customers. In connection with the acquisition,  AT&T UK's name was changed
      to Viatel Global Communications Limited.

      The purchase price for AT&T UK was $117.3 million, net of cash acquired of
      $24.1  million,  and was comprised of a $125.0 million cash payment at the
      time  of  closing,  certain  post  closing  payments  in  connection  with
      preliminary acquired working capital, and estimated transaction costs. The
      acquisition   has  been  accounted  for  under  the  purchase   method  of
      accounting.  The purchase price has been preliminarily  allocated based on
      estimated  fair  values  at  the  date  of   acquisition,   pending  final
      determination of certain acquired balances.  The preliminary allocation of
      the AT&T UK purchase price is as follows (in thousands):

      AT&T UK had significant transactions and relationships with AT&T Corp. and
      its affiliates.  As a result of these  relationships,  it is possible that
      the terms of these transactions were not the same as those that would have
      resulted from transactions among wholly unrelated parties.

(10)  RESTRUCTURING

      During 1999, the Company recognized  restructuring charges relating to the
      streamlining of the Company's  organizational  structure and the strategic
      repositioning of certain  operations,  primarily as a result of the merger
      with  Destia.  These  restructuring  charges  were  composed  primarily of
      anticipated  costs  to  terminate  certain  leases,   and  other  contract
      cancellation   costs  and  employee   termination  costs  associated  with
      workforce  reductions.  As of March 31, 2000,  approximately  55 employees
      have been terminated due to the Company's streamlining activities.

      At March 31,  2000,  the Company has accruals  for  restructuring  of $2.8
      million.   During   1999,   a  total  of  $3.9  million  was  accrued  for
      restructuring,  consisting  primarily  of  charges  relating  to  employee
      terminations  and lease and other contract  cancellation  costs.  Payments
      made  during  the  three   months   ended  March  31,  2000   against  the
      restructuring accruals totaled $1.1 million, of which $0.1 million related
      to  employee  terminations  and $1.0  million  related  to lease and other
      contract cancellation costs. The Company recorded additional restructuring
      charges  of $0.6  million  for the three  months  ended  March  31,  2000,
      primarily related to employee termination costs. Additionally,  during the
      three months ended March 31, 2000, the Company accelerated depreciation on
      certain  assets that were taken out of service as of March 31,  2000.  The
      Company  anticipates that all remaining  actions required to complete this
      restructuring plan will be completed by December 2000.

(11)  CONVERTIBLE PREFERRED STOCK

      On March 9, 2000,  the Company  completed  an offering of $325  million in
      Series B Cumulative  Convertible  Preferred  Stock for net proceeds to the
      Company of $306.1 million.  The Series B preferred stock accrues  interest
      at an annual rate of 7.50%,  may be  converted at the option of the holder
      at a conversion price of $46.25 per share and is mandatorily redeemable in
      February 2015. As part of this financing, the Company also issued warrants
      to purchase  753,116 shares of common stock,  50% of which are exercisable
      for 5 years at a price of $75 per share,  and 50% of which are exercisable
      for 7 1/2 years at a price of $100 per share.  In  addition,  the  Company
      issued  warrants to purchase 7,532 shares of its Series C preferred  stock
      (each  share of which is  convertible  into 100  shares  of the  Company's
      common  stock),  50% of which  are  exercisable  for 5 years at a price of
      $7,500  per share and 50% of which  are  exercisable  for 7 1/2 years at a
      price of $10,000 per share.

(12)  SUBSEQUENT EVENTS

      SALE OF TRUST CONVERTIBLE PREFERRED SECURITIES

      On April  12,  2000,  Viatel  Financing  Trust  I, a  Delaware  trust  and
      subsidiary of the Company (the "Trust"), sold $180 million of 7 3/4% trust
      convertible   preferred   securities.   The  trust  convertible  preferred
      securities  were sold  pursuant  to a private  placement  transaction.  In
      connection  therewith,  the Company received net proceeds of approximately
      $171.4 million.

      DEBT OFFERING

      On April 20,  2000,  the Company  completed a high yield  offering of E300
      million principal amount of 12 3/4% senior Euro notes due 2008 pursuant to
      a private  placement  transaction.  In connection  therewith,  the Company
      received net proceeds of approximately $277.8 million.

      TRANS-ATLANTIC CAPACITY

      On April 10, 2000, the Company executed a definitive  agreement with Level
      3  Communications  ("Level  3"),  under  the  terms of which  the  Company
      acquired a 25% ownership interest in the trans-Atlantic  fiber optic cable
      project being developed by Level 3. The Company's  required  commitment in
      2000 to fund this purchase is approximately $140 million.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS
        OF OPERATIONS

OVERVIEW

We   are  a   rapidly   growing   provider   of   "ALL   DISTANCE,"   integrated
telecommunication  services  to  individuals,   corporations,  internet  service
providers,  applications service providers and other communications  carriers in
Europe  and North  America.  We operate  one of  Europe's  largest  pan-European
networks,  with international gateways in New York City and London, direct sales
forces in 12 Western  European  cities and New York City,  and an indirect sales
force in numerous  locations in Western Europe and North  America.  We have full
public  telecommunications  operator licenses in ten Western European countries,
Canada and the United States and  interconnection  agreements with the incumbent
telecommunications provider in each of these countries.

Historically,  our  revenues  have been  derived  primarily  from  communication
services  and the  provision of  telecommunications  services in Europe and more
recently in North America.  Communication services revenue is comprised of Basic
and Advanced Services. Basic Services can be provided as both retail and carrier
services.  Our  Basic  Services  revenue  includes  revenue  from  switched  and
dedicated  long distance,  800 services,  conference  calling,  and enhanced fax
services as well as prepaid,  postpaid,  and debit calling cards. Basic Services
revenue is primarily  generated from billed minutes of use. Advanced Services is
comprised of domestic and international private line services,  Internet access,
frame relay,  asynchronous transfer mode, Internet protocol services and managed
bandwidth.  Advanced  Services  have been  offered as a response  to the growing
demand for such services from our customers and are  anticipated  to continue to
grow as a percentage of revenue.

Capacity  sales  include sales of dark fiber and leases of capacity that qualify
for sales-type  accounting.  Each revenue  source has a different  impact on our
results  of  operations.  Revenue  from  capacity  sales will  continue  to vary
substantially from period-to-period and will cause fluctuations in our operating
results.  These sales  substantially  increase  our gross  profit  (I.E.,  total
revenue  less cost of  services  and sales)  because  our cost of  communication

                                       13
<PAGE>


services as a percentage of  communications  service revenue is currently higher
than the cost of capacity  sales as a percentage of capacity  sales.  Due to the
timing of capacity sales and the higher margin  associated with such sales,  our
gross profits and gross margin may also fluctuate  substantially  in the future,
in ways that  will not  necessarily  reflect  the  trends  in our  communication
services  business.  We capitalize all of the costs  associated  with designing,
building,  funding and placing  each  portion of our  constructed  network  into
service.

In December  1999, we completed our  acquisition of Destia and in February 2000,
we  completed  our  acquisition  of AT&T UK.  As a result,  our  March 31,  2000
consolidated  financial  statements  include three months of results from Destia
and one month of operations from AT&T UK.

Revenue from  capacity  sales  consists  mainly of revenues  recognized  when we
deliver indefeasible rights-of-use that qualify for sales-type lease accounting.
Transactions  that do not meet the criteria for sales-type  lease accounting are
accounted for as operating leases and revenue is recognized over the term of the
lease and is included in communication  services  revenue.

RESULTS OF OPERATIONS

The following  table  summarizes the breakdown of our results of operations as a
percentage of revenue.  Our revenue,  and  therefore  these  percentages,  could
fluctuate  substantially  from  period-to-period  due to revenues  from capacity
sales, which have a substantially different impact on margins than revenues from
communications services.

         a measure of financial  performance under generally accepted accounting
         principles,  is not necessarily comparable to similarly titled measures
         of other  companies and should not be considered as an  alternative  to

                THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO THE
                       THREE MONTHS ENDED MARCH 31, 1999

TOTAL REVENUE. Total revenue increased by 193.1% to $180.7 million for the three
months ended March 31, 2000 from $61.6  million for the three months ended March
31, 1999. This growth was  attributable  to a 231.9% increase in  communications
services  revenue to $160.6  million for the three  months  ended March 31, 2000
from $48.4 million for the three months ended March  31,1999.  Billable  minutes
increased  to 1.4 billion for the three  months  ended March 31, 2000 from 270.8
million for the three  months  ended March 31,  1999.  Within the  communication
services   revenue  for  the  quarter  ended  March  31,  2000,  Basic  Services
represented $149.0 million,  or 92.8%,  compared to $47.7 million, or 98.6%, for
the quarter ended March 31, 1999.  Advanced  Services reached $11.7 million,  or
7.2%, of  communication  services revenue for the first quarter of 2000 compared
to $0.7  million,  or  1.4%,  for the  first  quarter  of 1999.  Capacity  sales
increased  to $20.0  million,  or 11.1%,  of total  revenue for the three months
ended March 31, 2000 from $13.2 million,  or 21.5%,  of total  revenue,  for the
three  months  ended  March  31,1999.  Revenue  growth in 2000  continues  to be
generated primarily by growth from our European operations,  capacity sales, and
as a result of the Destia and AT&T UK acquisitions.

Although there was a substantial increase in billable minutes from 1999 to 2000,
the  effects of such growth  were  partially  offset by a decline in revenue per
billable  minute,  which  declined by 41.2% to $.10 for the three  months  ended
March 31, 2000 from $.17 for the three months  ended March 31,  1999,  primarily
because of (1) a higher percentage of lower-priced  intra-European  and national
long distance traffic on our network and (2) reductions in prices in response to
price reductions by incumbent telecommunications operators and other carriers in
many  of our  markets.  Communications  services  revenue  per  billable  minute
excludes  fixed  monthly  fees  associated  with our other  products and service
offerings.

Communication  services  revenue  per  billable  minute  from  the sale of Basic
Services to retail  customers,  which represented 55.3% of revenue for the three
months ended March 31, 2000,  compared to 44.3% for the three months ended March
31, 1999, decreased 26.7% to $.11 for the three months ended March 31, 2000 from
$.15 for the three months ended March 31, 1999.  Communication  services revenue
per  billable  minute  from the sale of Basic  Services  to  carriers  and other
resellers decreased 60.0% to $.10 for the three months ended March 31, 2000 from
$.25 for the three months ended March 31, 1999.

For the three months ended March 31, 2000,  as compared to the same period ended
March 31, 1999, our Basic Services revenue derived from carrier services grew on
an absolute  basis.  Basic Services  revenue from carrier  services  represented
approximately  60.0% of revenue and approximately  36.9% of billable minutes for
the three  months  ended March  31,2000 as compared  to  approximately  34.2% of
revenue, and approximately 27.1% of billable minutes, for the three months ended
March 31, 1999.

COST OF SERVICES  AND SALES.  Cost of  services  and sales  increased  to $130.2
million for the three  months  ended  March 31, 2000 from $51.0  million for the
three months ended March 31, 1999. As a percentage of revenue,  however, cost of
services and sales decreased to  approximately  72.0% for the three months ended
March 31, 2000 from  approximately  82.8% for the three  months  ended March 31,
1999. This decrease was due to our migration from leased  infrastructure  to our
own  network,  capacity  sales  and the  Destia  and AT&T UK  acquisitions.  The
beneficial  effect of bringing  traffic  on-net,  however,  is somewhat  delayed
because our leased line agreements require minimum notification to terminate our
obligations.

Cost of services and sales for the three  months  ended March 31, 2000  includes
costs  associated  with capacity  sales.  The cost of capacity sales  represents
non-cash  charges of the PRO RATA cost of the network  assets and is  determined
based upon the ratio of total network  capacity sold to total estimated  network
capacity, multiplied by the total capitalized costs of the related network.

SELLING,   GENERAL   AND   ADMINISTRATIVE   EXPENSES.   Selling,   general   and
administrative  expenses  increased to $61.4  million for the three months ended
March 31, 2000 from $18.8 million for the three months ended March 31, 1999 and,
as a  percentage  of revenue,  increased  to  approximately  34.0% for the three
months ended March 31, 2000 from approximately  30.4% for the three months ended
March  31,  1999.  The  increase  was  primarily  the  result  of  the  expanded
geographical reach of our network,  additional product offering capabilities and
reorganization  expenses  related to our strategic  acquisitions.  Much of these
expenses are  attributable to overhead costs  associated with our  headquarters,
back-office  and  operations  as well as  maintaining  a  physical  presence  in
multiple jurisdictions. We expect to incur additional expenses as we continue to
invest  in  operating  infrastructure  and  actively  market  our  products  and
services.  Salaries and commissions,  as a percentage of total selling,  general
and administrative expenses, were approximately 46.9% for the three months ended
March 31, 2000  compared  to 44.7% for the three  months  ended March 31,  1999,
respectively.  As a  percentage  of total  selling,  general and  administrative
expenses,  advertising and promotion expenses were  approximately  7.1%, for the
three  months ended March 31, 2000 and 7.6% for the three months ended March 31,
1999.  Advertising  and  promotion  expenses  will  continue to be a significant
component of selling, general and administrative expenses in the future.

EBITDA LOSS.  EBITDA loss  increased to $10.9 million for the three months ended
March 31, 2000 from $8.2 million for the three months ended March 31, 1999. As a
percentage of revenue, EBITDA loss decreased to approximately 6.0% for the three
months ended March 31, 2000 from approximately  13.3% for the three months ended
March 31, 1999.

DEPRECIATION AND  AMORTIZATION.  Depreciation and  amortization  expense,  which
includes  depreciation of our network,  increased to approximately $66.7 million
for the three  months ended March 31, 2000 from  approximately  $9.6 million for
the three  months ended March 31,  1999.  The increase was due  primarily to the
increase in gross  property and equipment to $1.2 billion at March 31, 2000 from
$440.0  million  at  March  31,  1999  and  an  increase  of  $34.3  million  in
amortization of goodwill related to our acquisition of Destia.

As a result of our acquisition of Destia,  amortization expense will continue to
increase significantly in 2000. The purchase price for Destia was $901.9 million
and was  allocated  based on estimated  fair values at the date of  acquisition,
pending  final  determination.  This  preliminary  allocation  has  resulted  in
intangible  assets and  goodwill  of  approximately  $131.0  million  and $822.3
million,  respectively,  which are being amortized on a straight-line basis over
their  estimated  useful  lives which are four to seven  years and seven  years,
respectively.

RESTRUCTURING.  During 1999, we recognized restructuring charges relating to the
streamlining of our organizational  structure and the strategic repositioning of
certain  operations,  primarily  as a result of the merger  with  Destia.  These
restructuring  charges were composed primarily of anticipated costs to terminate
leases and certain other contracts in connection with the Company's streamlining
activities,  as well as employee  termination  costs  associated  with workforce
reductions.

At March 31, 2000, we had accruals for  restructuring  of $2.8  million.  During
1999,  a  total  of $3.9  million  was  accrued  for  restructuring,  consisting
primarily  of charges  relating  to  employee  terminations  and lease and other
contract  cancellation costs.  Payments made during the three months ended March
31, 2000 against the restructuring  accruals totaled $1.1 million, of which $0.1
million related to employee  terminations  and $1.0 million related to lease and
other contract cancellation costs. We recorded additional  restructuring charges
of $0.6 million for the three months ended March 31, 2000,  primarily related to
employee  termination costs.  Additionally,  during the three months ended March
31, 2000, we accelerated  depreciation  on certain assets that were taken out of
service as of March 31, 2000. We anticipate that all remaining  actions required
to complete the restructuring plan will be completed by December 2000.

INTEREST.  Interest  expense  increased to  approximately  $48.4 million for the
three months ended March 31, 2000 from approximately $26.2 million for the three
months  ended  March  31,  1999,  primarily  as a  result  of  increases  in our
outstanding  indebtedness,  which includes notes and capital lease  obligations,
which increased to $1.8 billion at March 31, 2000 from $1.3 billion at March 31,
1999.  For the three months ended March 31, 2000, we  capitalized  approximately
$4.2 million of interest costs.  Interest income increased to approximately $7.3
million for the three  months  ended March 31,  2000,  from  approximately  $6.8
million for the three months ended March 31, 1999,  primarily as a result of the
interim investment of the net proceeds from our 2000 Convertible Preferred Stock
offering.

     LIQUIDITY AND CAPITAL RESOURCES

We have  incurred  losses from  operating  activities in each year of operations
since our inception and expect to continue to incur operating and net losses for
the next several years. Since inception, we have used cash provided by financing
activities to fund operating losses,  interest expense and capital expenditures.
The sources of this cash have primarily  been through  private and public equity
and debt financings and, to a lesser extent,  equipment-based  financing.  As of
March 31,  2000,  we had  $516.8  million  of cash,  cash  equivalents  and cash
securing  letters  of credit for  network  construction  and  $159.5  million of
restricted cash equivalents and other restricted  marketable  securities,  which
primarily  secure  interest  payments  on our  notes  through  April  2001.  The
following private and public equity and debt financing provided funds to satisfy
our  liquidity  needs.  Giving effect to the April 12 and the April 20 offerings
described   herein,   pro  forma  restricted  and   non-restricted   cash,  cash
equivalents,  marketable  securities  and cash  securing  letters  of credit for
network construction as of March 31, 2000 was $1.1 billion.

On February 1, 2000,  we executed a securities  purchase  agreement  pursuant to
which we agreed to sell,  and  affiliates of Hicks,  Muse Tate & Furst and Chase
Capital  Partners  committed  to  buy,  $325  million  in  Series  B  cumulative
convertible  preferred  stock  for net  proceeds  to us of $306.1  million.  The
transaction  closed on March 9, 2000,  following  receipt  of  Hart-Scott-Rodino
Antitrust Improvements Act clearance.  Following the initial closing, affiliates
of Chase Capital  Partners  sold a portion of their Series B preferred  stock to
certain  affiliates of The  Blackstone  Group.  The net proceeds of this private
placement are being used for network expansion, services development and general
corporate purposes.

Destia's credit facility with NTFC Capital  Corporation,  under which Destia had
borrowed  approximately  $30.6  million  as of  March  31,  2000,  provides  for
borrowings to fund certain equipment acquisition costs and related expenses. All
of the equipment  purchased  with the proceeds of the NTFC note has been pledged
to NTFC. The terms of the NTFC facility  require the company to maintain certain
debt service  coverage  ratios,  EBITDA,  and minimum cash balances.  Due to the
Company's  acquisiton of Destia,  NTFC has the right to require  Destia to repay
all  outstanding  obligations  under the NTFC facility  within 90 days following
Viatel's  acquisition  of Destia.  NTFC has  extended  the date by which it must
exercise its right until May 26, 2000.  Before May 26, 2000, we will be required
to (i) obtain a waiver from NTFC, (ii) prepay the outstanding  amounts owed at a
premium of not more than 102% of the amount outstanding or (iii) negotiate a new
facility.  The Company's  intent is to renegotiate a new facility with NTFC and,
as such,  the Company  continues  to record the NTFC  borrowings  as a long term
liability.

On February  29,  2000,  we acquired  the entire  issued and  outstanding  share
capital of AT&T UK. The purchase price was $117.3 million,  net of cash acquired
of $24.1 million, and was comprised of a $125.0 million cash payment at the time
of closing,  certain post closing  payments in connection  with the  preliminary
acquired working capital, and estimated transaction costs.

During  the  second  quarter  of  2000,  we  intend  to file a  universal  shelf
registration  statement  that  will  enable  us to  issue,  from  time to  time,
additional shares of our common stock and preferred stock or debt securities. At
this time, we have not determined  the dollar amount of securities  that will be
registered  for  future  offerings.  We have no current  intention  to issue any
securities pursuant to this shelf registration in the immediate future.

We have very  substantial  interest  expense.  Although we have  restricted cash
available  to make our  interest  payments  on  certain  of our high  yield debt
instruments  through  April 15,  2001,  thereafter  we need to pay our  interest
expense from operating income or borrowings. During the three months ended March
31, 2000,  we had an operating  loss of $78.1  million and we have no commitment
from any lender to make funds available.

On April 12, 2000,  Viatel  Financing  Trust I, a Delaware  statutory  trust and
consolidated  subsidiary of ours, sold $180 million of 7 3/4% trust  convertible
preferred  securities.  The proceeds  from this offering have been loaned by the
trust to us. We will use the net proceeds of $171.4  million from this  offering
to further develop and enhance our network,  to make selective  acquisitions and
investments and for working capital and general corporate purposes.

On April 20,  2000,  we  completed a high yield  offering of 12 3/4% senior Euro
notes due 2008 through  which we received  approximately  $277.8  million of net
proceeds.



                                       17
<PAGE>



We believe that the net proceeds from the  offerings  discussed  above  together
with cash and  marketable  securities on hand and future  capacity  sales on our
network will provide  sufficient  funds for us to expand our business as planned
and to fund operating losses for the next 12 to 18 months.  However,  the amount
of our future capital requirements will depend on a number of factors, including
the success of our  business,  any  acquisitions  or  investments  we make,  the
start-up dates of each additional segment of our network,  the dates on which we
further  expand our  network,  whether  our  network  build-out  is on-time  and
on-budget,  the types of services we offer, staffing levels, and customer growth
as well as other factors that are not within our control,  including competitive
conditions,  government regulatory  developments and capital costs. Depending on
the factors  listed above,  we may need more capital or may be required to delay
or  abandon  some or all of our  development  and  expansion  plans or we may be
required  to  seek  additional  sources  of  financing  earlier  than  currently
anticipated.  If we are required to seek additional  financing,  there can be no
assurance that such financing will be available on acceptable terms, or at all.

         CAPITAL ADDITIONS; COMMITMENTS

The  development  of our  business  has required  substantial  capital.  Capital
additions  consist of capital  expenditures,  the net  increase in property  and
equipment purchases payable, assets acquired under capital lease obligations and
capitalized  interest  during the period.  For the three  months ended March 31,
2000,  capital  additions  totaled  $133.6  million  and  consisted  of  capital
expenditures of approximately $104.8 million, a net increase of $20.7 million in
property and equipment purchases payable,  $3.9 million of assets acquired under
capital lease obligations and capitalized interest of $4.2 million. We have also
entered  into  certain   agreements   associated  with  our  network,   purchase
commitments  for network  expansion  and other items  aggregating  approximately
$210.0  million at March 31,  2000.  We expect to continue  to have  substantial
capital expenditures in the future.

In addition,  on April 10, 2000, we executed a definitive agreement with Level 3
Communications  under the terms of which we acquired a 25% ownership interest in
the  trans-Atlantic  fiber optic cable project  being  developed by Level 3. Our
required commitment in 2000 to fund this purchase is approximately $140 million.

         FOREIGN CURRENCY

We have  exposure to  fluctuations  in foreign  currencies  relative to the U.S.
Dollar as a result of billing portions of our communications services revenue in
the local European  currency in countries where the local currency is relatively
stable while many of our  obligations,  including a  substantial  portion of our
transmission  costs,  are  denominated in U.S.  dollars.  In countries with less
stable currencies, we bill in U.S. dollars. Debt service on certain of the notes
issued by us is currently payable in Euros. A substantial portion of our capital
expenditures  is  and  will  continue  to be  denominated  in  various  European
currencies,  including the Euro. Most of the European  currencies in which we do
business  converged on January 1, 1999,  with the exception of the British Pound
Sterling.

A significant  portion of our assets are  foreign-denominated  and, as such, are
subject to  fluctuations  in value due to movements in foreign  exchange  rates.
With the continued  expansion of our network, a substantial portion of the costs
associated with the network,  such as local access and termination charges and a
portion  of the  leased  line  costs,  as well as a  majority  of local  selling
expenses and debt service related to the Euro denominated  notes, are charged to
us in the same  currencies  as revenue is billed.  These  developments  create a
natural hedge against a portion of our foreign exchange exposure.  Our financial
position as of March 31, 2000 and our results of operations for the three months
ended March 31, 2000 were not significantly affected by fluctuations in the U.S.
Dollar in relation to foreign currencies.

EURO

On January 1, 1999, eleven of the fifteen member countries of the European Union
established  irrevocable fixed conversion rates between their existing sovereign
currencies and a single currency  called the Euro. The sovereign  currencies are
scheduled  to  remain  legal  tender  as  denominations  of the  Euro  during  a
transition period from January 1, 1999 to January 1, 2002.

We have  completed an internal  analysis  regarding  business and systems issues
related to the Euro conversion and, as a result, made necessary modifications to
our business processes and software  applications.  Throughout most of 1999, and
the three months  ended March 31, 2000 we have been able to conduct  business in
both the Euro and sovereign  currencies on a parallel  basis, as required by the
European Union.

We  believe  that the Euro  conversion  has not and will not have a  significant
impact on our  business  in Europe.  The costs to convert all systems to be Euro
compliant did not have a significant impact on our results of operations.

INFLATION

We do not believe that inflation has had a significant  effect on our operations
to date.

RECENT ACCOUNTING PRONOUNCEMENTS

SFAS NO. 133 AND SFAS NO. 137. Statement of Financial  Accounting  Standards No.
133  ("SFAS  133,")   "Accounting   for  Derivative   Instruments   and  Hedging
Activities,"  was issued in June 1998. SFAS 133  standardizes the accounting for
derivative  instruments,  including certain derivative  instruments  embedded in
other  contracts,  by requiring  recognition of those  instruments as assets and
liabilities  and to measure  them at fair value.  In June 1999,  the FASB issued
Statement of Financial  Accounting Standards No. 137, "Accounting for Derivative
Instruments  and Hedging  Activities  - Deferral of the  Effective  Date of SFAS
133," which amends SFAS 133 to delay the date by which all companies must comply
with  SFAS  133.  Companies  must  comply  with  SFAS 133 for all  fiscal  years
beginning  after June 15, 2000. We have not completed our analysis of the impact
of these statements on our consolidated financial statements.

In March 2000, FASB Interpretation No. 44 - "Accounting for Certain Transactions
involving Stock  Compensation,  an  interpretation  of APB Opinion No. 25" ("FIN
44") was issued.  FIN 44 clarifies the  application  of APB No. 25 regarding (a)
the definition of EMPLOYEE for purposes of applying APB No. 25, (b) the criteria
for  determining  whether a plan  qualifies as a  noncompensatory  plan, (c) the
accounting  consequence  of various  modifications  to the terms of a previously
fixed stock  option or award,  and (d) the  accounting  for an exchange of stock
compensation  awards in a  business  combination.  FIN 44 does not  address  the
application  of the fair value method of Statement No. 123. This  Interpretation
is effective July 1, 2000, but certain conclusions in this Interpretation  cover
specific  events that occur after either December 15, 1998, or January 12, 2000.
To the extent that this Interpretation covers events occurring during the period
after  December 15, 1998, or January 12, 2000,  but before the effective date of
July 1, 2000,  the effects of applying this  Interpretation  are recognized on a
prospective basis from July 1, 2000. The Company has not yet assessed the impact
of FIN 44.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are subject to foreign currency  exchange rate risk relating to receipts from
customers,  payments to suppliers  and interest  and  principal  payments on our
outstanding Euro  denominated  senior notes and senior discount notes in foreign
currencies.  We do not  consider  the market risk  exposure  relating to foreign
currency  exchange to be  material.  See "Item 2.  Management's  Discussion  and
Analysis of  Financial  Condition  and  Results of  Operations  - Liquidity  and
Capital Resources - Foreign Currency."

We have  financial  instruments,  which  are  subject  to  interest  rate  risk,
principally  short-term investments and debt obligations issued at a fixed rate.
Historically,  we have not experienced  material gains or losses due to interest
rate changes when selling  short-term  investments  and typically  holding these
securities until maturity.  Based on current holdings of short-term investments,
our exposure to interest rate risk is not material.  Fixed-rate debt obligations
issued by us are generally not callable until maturity.

ITEM 2.      CHANGES IN SECURITIES AND USE OF PROCEEDS.

On March 9,  2000,  the  Company  completed  the sale of $325  million  of 7.50%
Cumulative Convertible Preferred Stock Series B due 2015, liquidation preference
$1072,  par value $.01 (the "Series B Preferred  Stock") to affiliates of Hicks,
Muse, Tate & Furst,  Chase Capital Partners and The Blackstone Group. The Series
B Preferred  Stock was issued in two  tranches  -- Series B-1,  which has voting
rights (the "Series B-1 Preferred Stock") and Series B-2, which generally has no
voting  rights (the "Series B-2  Preferred  Stock").  The net proceeds from this
offering were $306.1  million,  which the Company is using to continue its build
out of the Viatel network,  to fund new  initiatives  and for general  corporate
purposes.

All shares of Series B Preferred Stock were issued pursuant to an
exemption from the  registration  requirements of the Securities Act of 1933, as
amended  (the  "Act"),  under  Section  4(2) of the Act.  Theses sales were made
without any general solicitation or advertising.  The Series B-1 Preferred Stock
is  convertible,  generally  at any  time,  into the  Company's  fully  paid and
non-assessable  shares  of common  stock.  The  Series  B-2  Preferred  Stock is
convertible,   generally  at  any  time,   into  a  number  of  fully  paid  and
non-assessable  shares  of  Series  C  preferred  stock  (calculated  as to each
conversion  to the  nearest  1/10,000  of a share)  equal to the then  effective
liquidation  preference thereof plus accrued and unpaid dividends to the date of
conversion  divided by the conversion  price in effect at the time of conversion
divided by 100. The initial conversion price for the Series B Preferred Stock is
$46.25 per share.

As part of this  financing,  the Company  issued  warrants  to purchase  753,116
shares of its common  stock,  50% of which are  exercisable  for five years at a
price of $75 per share,  and 50% of which are exercisable for seven and one half
years at a price of $100 per share. The Company also issued warrants to purchase
7,532 shares of its Series C preferred  stock,  50% of which are exercisable for
five years at a price of $7,500 per share and 50% of which are  exercisable  for
seven and one half years at a price of $10,000 per share.

     the Common Securities are deemed to have waived such Event of Default under

     such Event of  Default  under the  Declaration  as  provided  below in this
     Section  2.6(b),  the Event of Default  under the  Declaration  may only be
     waived by the vote of the Holders of at least the proportion in liquidation
     amount of the Common Securities that the relevant Super Majority represents

provided  further,  that each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default  with  respect to the
Common Securities and its consequences  until all Events of Default with respect
to the Convertible  Preferred  Securities  have been cured,  waived or otherwise
eliminated,  and until  such  Events of  Default  have been so cured,  waived or
otherwise  eliminated,  the Institutional  Trustee shall act solely on behalf of

Trustee to act in  accordance  with the terms of the  Securities.  The foregoing
provisions of this Section 2.6(b) shall be in lieu of Sections  316(a)(1)(A) and

316(a)(1)(B) of the Trust Indenture Act are hereby expressly  excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act. Subject
to the foregoing  provisions of this Section 2.6(b),  upon such waiver, any such
default shall cease to exist and any Event of Default with respect to the Common
Securities  arising  therefrom  shall be  deemed  to have  been  cured for every
purpose of this  Declaration,  but no such waiver shall extend to any subsequent
or other  default or Event of Default with respect to the Common  Securities  or
impair any right consequent thereon.

     (c)  A  waiver  of  an  Event  of  Default   under  the  Indenture  by  the
Institutional  Trustee  at the  direction  of  the  Holders  of the  Convertible
Preferred Securities, constitutes a waiver of the corresponding Event of Default
under this Declaration. The foregoing provisions of this Section 2.6(c) shall be
in lieu of Section  316(a)(1)(B)  of the Trust  Indenture  Act and such  Section


                                       11

Responsible  Officer of the Institutional  Trustee in good faith determines that
the  withholding  of such  notice  is in the  interests  of the  Holders  of the
Securities.  Any such notice given  pursuant to this Section  2.7(a) shall state
that an Event of  Default  under  the  Indenture  also  constitutes  an Event of
Default under this Declaration.

default except:

          (i) a default under Sections 5.1(a) and 5.1(b) of the Indenture; or

constitute  the act of and serve to bind the  Trust  and an action  taken by the
Institutional Trustee on behalf of the Trust in accordance with its powers shall

entitled to rely  conclusively on the power and authority of the Trustees as set
forth in this Declaration.

law,  any Regular  Trustee is  authorized  to execute on behalf of the Trust any
documents  which the Regular  Trustees have the power and authority to cause the
Trust to  execute  pursuant  to Section  3.6,  provided,  that the  registration
statement referred to in Section 3.6, including any amendments  thereto,  shall,

     affairs of and liquidation of the Trust and the preparation,  execution and
     filing of any  certificate of  cancellation  with the Secretary of State of
     the State of Delaware.

     SECTION 3.7. PROHIBITION OF ACTIONS BY THE TRUST AND THE TRUSTEES

     (a) The Trust shall not,  and the  Trustees  (including  the  Institutional
Trustee)  shall  cause the Trust not to  engage in any  activity  other  than as
required or authorized by this  Declaration.  In particular  the Trust shall not
and the Trustees (including the Institutional Trustee) shall cause the Trust not

     where such consent  shall be required  unless the Trust shall have received
     an opinion of counsel to the effect that such  modification  will not cause
     more  than an  insubstantial  risk  that (x) the  Trust  will be  deemed an
     Investment  Company required to be registered under the Investment  Company
     Act or (y) the Trust will not be  classified  as a grantor trust for United
     States federal income tax purposes.

     SECTION 3.8. POWERS AND DUTIES OF THE INSTITUTIONAL TRUSTEE

     (a) The legal title to the Debentures  shall be owned by and held of record
in the name of the  Institutional  Trustee in trust for the benefit of the Trust
and the  Holders  of the  Securities.  The  right,  title  and  interest  of the
Institutional  Trustee to the Debentures shall vest automatically in each Person
who may  hereafter be  appointed as  Institutional  Trustee in  accordance  with
Section 5.6. To the fullest extent  permitted by law, such vesting and cessation
of title shall be effective whether or not conveyancing documents with regard to
the Debentures have been executed and delivered.

     (b) The  Institutional  Trustee  shall not  transfer  its right,  title and
interest in the  Debentures to the Regular  Trustees or to the Delaware  Trustee
(if the Institutional Trustee does not also act as Delaware Trustee).

     (c) The Institutional Trustee shall:

          (i)  establish  and maintain a segregated  non-interest  bearing trust
     account (the "INSTITUTIONAL  TRUSTEE ACCOUNT") in the name of and under the
     exclusive control of the Institutional  Trustee on behalf of the Holders of
     the  Securities  and, upon the receipt of payments of funds made in respect
     of the Debentures  held by the  Institutional  Trustee,  deposit such funds
     into the Institutional  Trustee Account and make payments to the Holders of
     the Convertible  Preferred  Securities and Holders of the Common Securities
     from the  Institutional  Trustee  Account in  accordance  with Section 6.1.
     Funds in the  Institutional  Trustee Account shall be held uninvested until
     disbursed in accordance with this Declaration.  The  Institutional  Trustee
     Account shall be an account that is maintained  with a banking  institution
     the rating on whose long-term  unsecured  indebtedness is at least equal to
     the rating  assigned to the  Convertible  Preferred  Securities (or, if the
     Convertible  Preferred  Securities  are not rated,  the rating  assigned to
     Viatel's  senior  debt)  by a  "nationally  recognized  statistical  rating
     organization," as that term is defined for purposes of Rule 436(g)(2) under
     the Securities Act;



                                       18
<PAGE>

          (ii) engage in such  ministerial  activities  as shall be necessary or
     appropriate  to  effect  the  redemption  of  the   Convertible   Preferred
     Securities  and the Common  Securities  to the extent  the  Debentures  are
     redeemed or mature;

          (iii) engage in such  ministerial  activities as shall be necessary or
     appropriate to effect the  distribution of the Trust Property in accordance
     with the terms of this Declaration; and

          (iv)  to the  extent  provided  for in  this  Declaration,  take  such
     ministerial  actions  necessary  in  connection  with the winding up of the
     affairs of and liquidation of the Trust.

     (d) The  Institutional  Trustee  shall take all actions  and  perform  such
duties as may be specifically  required of the Institutional Trustee pursuant to
the terms of the Securities.

     (e) The Institutional  Trustee shall take any Legal Action which arises out
of or in connection with, an Event of Default of which a Responsible  Officer of
the Institutional Trustee has actual knowledge,  or the Institutional  Trustee's
duties  and  obligations  under this  Declaration  or the Trust  Indenture  Act;
provided,  however,  that if a Declaration  Event of Default has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay  interest or  principal on the  Debentures  on the date such  interest or
principal is otherwise payable (or in the case of redemption,  on the redemption
date), then a Holder of Convertible  Preferred Securities may directly institute
a proceeding  for  enforcement  of payment to such Holder of the principal of or
interest on the  Debentures  having a principal  amount  equal to the  aggregate
liquidation  amount of the  Convertible  Preferred  Securities of such Holder (a
"DIRECT ACTION") on or after the respective due date specified in the Debentures
and provided,  further,  that if the Institutional  Trustee fails to enforce its
rights under the Debentures, any Holder of Convertible Preferred Securities may,
to the fullest extent permitted by law, institute a legal proceeding against any
Person to enforce the  Institutional  Trustee's rights under the Debentures.  In
connection with such Direct Action, the Holders of the Common Securities will be
subrogated to the rights of such Holder of Convertible  Preferred  Securities to
the  extent  of any  payment  made by the  Debenture  Issuer  to such  Holder of
Convertible  Preferred  Securities in such Direct Action.  Except as provided in
the preceding  sentences,  the Holders of Convertible  Preferred Securities will
not be able to exercise  directly any other  remedy  available to the holders of
the Debentures.

     (f) The  Institutional  Trustee shall  continue to serve as a Trustee until
either:

          (i) the Trust has been  completely  liquidated and the proceeds of the
     liquidation  distributed to the Holders of Securities pursuant to the terms
     of the Securities; or



                                       19
<PAGE>

          (ii) a  Successor  Institutional  Trustee has been  appointed  and has
     accepted that appointment in accordance with Section 5.6.

     (g) The Institutional Trustee shall have the legal power to exercise all of
the rights,  powers and privileges of a holder of Debentures under the Indenture
and,  if an Event of  Default  actually  known to a  Responsible  Officer of the
Institutional Trustee occurs and is continuing, the Institutional Trustee shall,
for the  benefit of Holders of the  Securities,  enforce its rights as holder of
the  Debentures  subject to the rights of the  Holders  pursuant to the terms of
such Securities.

     (h) The  Institutional  Trustee may authorize one or more Persons  (each, a
"PAYING  AGENT")  to  pay  Distributions,  redemption  payments  or  Liquidation
Distributions on behalf of the Trust with respect to all Securities and any such
Paying Agent shall comply with Section  317(b) of the Trust  Indenture  Act. Any
Paying  Agent may be  removed  by the  Institutional  Trustee  at any time and a
successor Paying Agent or additional  Paying Agents may be appointed at any time
by the Institutional Trustee.

     (i) Subject to this Section 3.8, the Institutional  Trustee shall have none
of the duties, liabilities,  powers or the authority of the Regular Trustees set
forth in Section 3.6.

     The  Institutional  Trustee  must  exercise  the  powers  set forth in this
Section 3.8 in a manner that is  consistent  with the purposes and  functions of
the Trust set out in Section 3.3, and the  Institutional  Trustee shall not take
any action that is inconsistent with the purposes and functions of the Trust set
out in Section 3.3.

     SECTION  3.9.  CERTAIN  DUTIES AND  RESPONSIBILITIES  OF THE  INSTITUTIONAL
TRUSTEE.

     (a) The  Institutional  Trustee,  before  the  occurrence  of any  Event of
Default  and after the curing of all Events of Default  that may have  occurred,
shall  undertake  to perform only such duties as are  specifically  set forth in
this  Declaration and no implied  covenants shall be read into this  Declaration
against the  Institutional  Trustee.  In case an Event of Default  has  occurred
(that  has not  been  cured  or  waived  pursuant  to  Section  2.6) of  which a
Responsible  Officer of the  Institutional  Trustee  has actual  knowledge,  the
Institutional  Trustee shall exercise such of the rights and powers vested in it
by this  Declaration,  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 his or her own affairs.

     (b) No  provision  of this  Declaration  shall be  construed to relieve the
Institutional  Trustee from  liability  for its own  negligent  action,  its own
negligent failure to act, or its own willful misconduct, except that:

          (i)  prior to the  occurrence  of an Event of  Default  and  after the
     curing or waiving of all such Events of Default that may have occurred:



                                       20
<PAGE>

               (A) the duties and obligations of the Institutional Trustee shall
          be determined solely by the express provisions of this Declaration and
          the  Institutional   Trustee  shall  not  be  liable  except  for  the
          performance  of such duties and  obligations as are  specifically  set
          forth in this  Declaration,  and no implied  covenants or  obligations
          shall be read into this Declaration against the Institutional Trustee;
          and

               (B) in the absence of bad faith on the part of the  Institutional
          Trustee,  the Institutional  Trustee may conclusively  rely, as to the
          truth of the statements and the correctness of the opinions  expressed
          therein,   upon  any   certificates  or  opinions   furnished  to  the
          Institutional  Trustee  and  conforming  to the  requirements  of this
          Declaration; but in the case of any such certificates or opinions that
          by any provision hereof are  specifically  required to be furnished to
          the Institutional  Trustee, the Institutional Trustee shall be under a
          duty to examine the same to  determine  whether or not they conform to
          the  requirements  of  this  Declaration  (but  need  not  confirm  or
          investigate  the accuracy of any  mathematical  calculations  or other
          facts stated therein);

          (ii) the  Institutional  Trustee  shall not be liable for any error of
     judgment made in good faith by a Responsible  Officer of the  Institutional
     Trustee,  unless  it shall be proved  that the  Institutional  Trustee  was
     negligent in ascertaining the pertinent facts;

          (iii) the  Institutional  Trustee  shall not be liable with respect to
     any action  taken or omitted to be taken by it in good faith in  accordance
     with  the  direction  of  the  Holders  of not  less  than  a  Majority  in
     liquidation amount of the Securities relating to the time, method and place
     of conducting any proceeding for any remedy available to the  Institutional
     Trustee,  or exercising any trust or power conferred upon the Institutional
     Trustee under this Declaration;

          (iv) no provision of this Declaration  shall require the Institutional
     Trustee  to  expend  or risk its own  funds  or  otherwise  incur  personal
     financial  liability  in the  performance  of any of its  duties  or in the
     exercise  of any of its  rights  or  powers,  if it shall  have  reasonable
     grounds for believing  that the repayment of such funds or liability is not
     reasonably  assured to it under the terms of this  Declaration or indemnity
     reasonably  satisfactory to the Institutional  Trustee against such risk or
     liability is not reasonably assured to it;

          (v) the Institutional Trustee's sole duty with respect to the custody,
     safe  keeping  and  physical   preservation   of  the  Debentures  and  the
     Institutional  Trustee  Account  shall be to deal with such  property  in a
     similar manner as the Institutional Trustee deals with similar property for
     its own account,  subject to the  protections  and limitations on liability
     afforded to the Institutional  Trustee under this Declaration and the Trust
     Indenture Act;



                                       21
<PAGE>

          (vi) the Institutional  Trustee shall have no duty or liability for or
     with respect to the value,  genuineness,  existence or  sufficiency  of the
     Debentures or the payment of any taxes or assessments  levied thereon or in
     connection therewith;

          (vii) the  Institutional  Trustee shall not be liable for any interest

     Trustee  to so act or as to  its  compliance  with  any  of the  terms  and
     provisions  of  this  Declaration,  both of  which  shall  be  conclusively
     evidenced by the Institutional Trustee's or its agent's taking such action;

          (x)  whenever  in  the   administration   of  this   Declaration   the
     Institutional   Trustee   shall  deem  it  desirable  to  receive   written
     instructions  with respect to  enforcing  any remedy or right or taking any
     other action hereunder,  the Institutional  Trustee (i) may request written

shall be  unqualified  or  incompetent  in accordance  with  applicable  law, to
perform any such act or acts,  or to exercise  any such  right,  power,  duty or
obligation.  No  permissive  power or authority  available to the  Institutional

Section 3.4(d), be signed by all of the Regular Trustees.

     SECTION 3.13. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

organized as such under the laws of any State; provided that

          (i) such successor entity (the "SUCCESSOR ENTITY") either:

               (A) expressly  assumes all of the  obligations of the Trust under
          the Securities; or

               (B) substitutes for the Convertible  Preferred  Securities  other
          securities  having  substantially  the same  terms as the  Convertible
          Preferred  Securities  (the  "SUCCESSOR  SECURITIES")  so  long as the
          Successor  Securities  rank  the  same  as the  Convertible  Preferred
          Securities  rank with  respect  to  Distributions  and  payments  upon
          liquidation, redemption and otherwise;

          (ii) the  Debenture  Issuer  expressly  acknowledges  a trustee of the

                                       25
<PAGE>

          (iii) such merger, consolidation, amalgamation or replacement does not
     cause  the  Convertible   Preferred  Securities  (including  any  Successor
     Securities)  to be  downgraded  by any  nationally  recognized  statistical
     rating organization;

          (iv) such merger, consolidation,  amalgamation or replacement does not
     adversely  affect the rights,  preferences and privileges of the Holders of
     the Securities (including any Successor Securities) in any material respect
     (other than with respect to any  dilution of the  Holders'  interest in the
     Successor Entity);

          (v) such  Successor  Entity  has a  purpose  identical  to that of the
     Trust;

          (vi) prior to such merger, consolidation, amalgamation or replacement,
     the Sponsor has received an opinion of  nationally  recognized  independent
     counsel to the Trust experienced in such matters to the effect that:

               (A) such merger, consolidation,  amalgamation or replacement does
          not adversely  affect the rights,  preferences  and  privileges of the
          Holders of the Securities  (including any Successor Securities) in any
          material  respect  (other  than with  respect to any  dilution  of the
          Holders' interest in the Successor Entity);

               (B)  following  such  merger,   consolidation,   amalgamation  or
          replacement,  neither  the  Trust  nor the  Successor  Entity  will be
          required to register as an Investment Company; and

               (C)  following  such  merger,   consolidation,   amalgamation  or
          replacement,  the Trust (or such Successor Entity) will continue to be
          classified  as a grantor trust for United  States  federal  income tax
          purposes; and

          (vii) the Sponsor  guarantees the obligations of the Successor  Entity
     under the  Successor  Securities  at least to the  extent  provided  by the
     Securities Guarantees.

     (c) Notwithstanding  Section 3.15(b),  the Trust shall not, except with the
consent of Holders of 100% in liquidation amount of the Securities, consolidate,
amalgamate, merge with or into, or be replaced by any other entity or permit any
other entity to consolidate,  amalgamate,  merge with or into, or replace it, if
such consolidation, amalgamation, merger or replacement would cause the Trust or
the  Successor  Entity to be classified as other than a grantor trust for United
States federal income tax purposes.

          and

          (ii) no such  resignation  of the  Trustee  that acts as the  Delaware
     Trustee  shall be  effective  until a Successor  Delaware  Trustee has been
     appointed and has accepted such appointment by instrument  executed by such
     Successor  Delaware Trustee and delivered to the Trust, the Sponsor and the
     resigning Delaware Trustee.

     (d) The Holders of the Common  Securities  shall use their best  efforts to
promptly appoint a Successor Delaware Trustee or Successor Institutional Trustee
as the case may be if the Institutional Trustee or the Delaware Trustee delivers
an instrument of resignation in accordance with this Section 5.6.

     (e) If no Successor  Institutional  Trustee or Successor  Delaware  Trustee
shall have been  appointed and accepted  appointment as provided in this Section
5.6 within 60 days after  delivery of an instrument of  resignation  or removal,
the  Institutional  Trustee or Delaware Trustee  resigning or being removed,  as
applicable,  may petition, at the expense of the Sponsor, any court of competent
jurisdiction for appointment of a Successor  Institutional  Trustee or Successor
Delaware  Trustee.  Such court may thereupon,  after prescribing such notice, if
any, as it may deem  proper and  prescribe,  appoint a  Successor  Institutional
Trustee or Successor Delaware Trustee, as the case may be.

     (f) No  Institutional  Trustee or Delaware  Trustee shall be liable for the
acts or omissions  to act of any  Successor  Institutional  Trustee or Successor
Delaware Trustee, as the case may be.

     SECTION 5.7. VACANCIES AMONG TRUSTEES.

     If a  Trustee  ceases  to hold  office  for any  reason  and the  number of
Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is
increased  pursuant  to  Section  5.1,  a  vacancy  shall  occur.  A  resolution
certifying  the  existence of such vacancy by the Regular  Trustees or, if there
are more than two,  a  majority  of the  Regular  Trustees  shall be  conclusive
evidence of the  existence of such  vacancy.  The vacancy shall be filled with a
Trustee appointed in accordance with Section 5.6.

     SECTION 5.8. EFFECT OF VACANCIES.

     The  death,  resignation,  retirement,  removal,  bankruptcy,  dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee shall
not  operate  to annul the  Trust.  Whenever  a vacancy in the number of Regular
Trustees  shall  occur,  until such  vacancy is filled by the  appointment  of a
Regular Trustee in accordance with Section 5.6, the Regular  Trustees in office,
regardless  of their  number,  shall have all the powers  granted to the Regular
Trustees and shall discharge all the duties imposed upon the Regular Trustees by
this Declaration.

     SECTION 5.9. MEETINGS.

     If there is more than one Regular Trustee, meetings of the Regular Trustees
shall be held from time to time upon the call of any  Regular  Trustee.  Regular
meetings  of the  Regular  Trustees  may be held at a time  and  place  fixed by
resolution  of the Regular  Trustees.  Notice of any  in-person  meetings of the
Regular  Trustees  shall be hand  delivered  or  otherwise  delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 48
hours  before such  meeting.  Notice of any  telephonic  meetings of the Regular
Trustee or any committee thereof shall be hand delivered or otherwise  delivered
in writing  (including by facsimile,  with a hard copy by overnight courier) not
less than 24 hours before a meeting.  Notices shall contain a brief statement of
the time, place and anticipated  purposes of the meeting.  The presence (whether
in person or by telephone) of a Regular Trustee at a meeting shall  constitute a
waiver of notice  of such  meeting  except  where a  Regular  Trustee  attends a
meeting for the express  purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened.  Unless
provided  otherwise in this Declaration,  any action of the Regular Trustees may
be taken at a meeting  by vote of a majority  of the  Regular  Trustees  present
(whether in person or by  telephone)  and  eligible to vote with respect to such
matter, provided that a Quorum is present, or without a meeting by the unanimous
written consent of the Regular Trustees.  In the event there is only one Regular
Trustee,  any and all action of such  Regular  Trustee  shall be  evidenced by a
written consent of such Regular Trustee.

     SECTION 5.10. DELEGATION OF POWER.

     A Regular Trustee may, by power of attorney consistent with applicable law,
delegate to any other natural person over the age of 21 his or her power for the
purposes of executing any documents  contemplated in Section 3.6,  including any
registration statement or amendment thereto filed with the Commission, or making
any other governmental filing.

     The Regular Trustees shall have power to delegate from time to time to such
of their  number or to  officers  of the Trust the doing of such  things and the
execution  of such  instruments  either in the name of the Trust or the names of
the Regular Trustees or otherwise as the Regular Trustees may deem expedient, to
the extent such  delegation is not  prohibited by applicable  law or contrary to
the provisions of the Trust, as set forth herein.

     SECTION 5.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any  corporation  into  which the  Institutional  Trustee  or the  Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be  consolidated,  or any corporation  resulting from any merger,  conversion or
consolidation to which the Institutional Trustee or the Delaware Trustee, as the
case  may  be,  shall  be a  party,  or  any  corporation  succeeding  to all or
substantially all the corporate trust business of the  Institutional  Trustee or
the  Delaware  Trustee,  as the  case  may be,  shall  be the  successor  of the
Institutional  Trustee or the Delaware  Trustee,  as the case may be, hereunder,
provided such corporation  shall be otherwise  qualified and eligible under this
Article,  without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

Distributions  shall be made on the  Convertible  Preferred  Securities  and the
Common  Securities  in  accordance  with  the  preferences  set  forth  in their
respective terms. If and to the extent that the Debenture Issuer makes a payment
of interest  (including  Compound  Interest  (as defined in the  Indenture)  and
Additional Sums (as defined in the Indenture)),  premium and/or principal on the
Debentures  held by the  Institutional  Trustee  (the amount of any such payment
being a "PAYMENT AMOUNT"),  the Institutional  Trustee shall and is directed, to
the extent funds are  available  for that  purpose,  to make a  distribution  (a
"DISTRIBUTION") of the Payment Amount to Holders.

                             ISSUANCE OF SECURITIES

     SECTION 7.1. GENERAL PROVISIONS REGARDING SECURITIES.

     (a) The  Regular  Trustees  shall on behalf of the Trust issue one class of
convertible preferred securities  representing undivided beneficial interests in
the  assets  of the  Trust  having  such  terms as are set forth in Annex I (the
"CONVERTIBLE   PREFERRED  SECURITIES")  and  one  class  of  convertible  common
securities  representing  undivided  beneficial  interests  in the assets of the
Trust having such terms as are set forth in Annex I (the  "COMMON  SECURITIES").
The Trust  shall issue no  securities  or other  interests  in the assets of the
Trust other than the Convertible Preferred Securities and the Common Securities.

     (b)  The  consideration  received  by the  Trust  for the  issuance  of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

     (c) Upon issuance of the  Securities as provided in this  Declaration,  the
Securities  so issued  shall be  deemed to be  validly  issued,  fully  paid and
non-assessable.

     (d) Every  Person,  by virtue  of having  become a Holder or a  Convertible
Preferred  Security  Beneficial  Owner  in  accordance  with  the  terms of this
Declaration,  shall be deemed to have expressly assented and agreed to the terms
of and shall be bound by this Declaration.

     SECTION 7.2. EXECUTION AND AUTHENTICATION.

     (a) The  Certificates  shall be  signed on behalf of the Trust by a Regular
Trustee.  In case any Regular  Trustee of the Trust who shall have signed any of
the Securities shall cease to be such Regular Trustee before the Certificates so
signed shall be delivered by the Trust,  such  Certificates  nevertheless may be
delivered as though the person who signed such Certificates had not ceased to be
such Regular  Trustee;  and any Certificate may be signed on behalf of the Trust
by such persons who, at the actual date of execution of such Security,  shall be
the Regular  Trustees of the Trust,  although at the date of the  execution  and
delivery of the Declaration any such person was not such a Regular Trustee.

     (b) One Regular Trustee shall sign the Convertible Preferred Securities for
the Trust by manual or facsimile  signature.  Unless otherwise determined by the
Trust,  such  signature  shall,  in the case of Common  Securities,  be a manual
signature.



                                       34
<PAGE>

     A Convertible  Preferred Security shall not be valid until authenticated by
the manual signature of an authorized  signatory of the  Institutional  Trustee.
The  signature  shall be  conclusive  evidence  that the  Convertible  Preferred
Security has been authenticated under this Declaration.

     Upon a  written  order of the  Trust  signed by one  Regular  Trustee,  the
Institutional  Trustee shall authenticate the Convertible  Preferred  Securities
for original issue.

     The Institutional Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate  Convertible Preferred  Securities.  An authenticating
agent  may   authenticate   Convertible   Preferred   Securities   whenever  the
Institutional  Trustee  may  do  so.  Each  reference  in  this  Declaration  to
authentication  by the  Institutional  Trustee includes  authentication  by such
agent. An authenticating agent has the same rights as the Institutional  Trustee
to deal with the Company or an Affiliate.

     SECTION 7.3. FORM AND DATING.

     The  Convertible  Preferred  Securities  and  the  Institutional  Trustee's
certificate of authentication  shall be substantially in the form of Exhibit A-1
and the Common  Securities  shall be  substantially  in the form of Exhibit A-2,
each of  which  is  hereby  incorporated  in and  expressly  made a part of this
Declaration.  Certificates  may be printed,  lithographed  or engraved or may be
produced  in any  other  manner  as is  reasonably  acceptable  to  the  Regular
Trustees,  as evidenced by their  execution  thereof.  The  Securities  may have
letters,  numbers,  notations,  other marks of  identification or designation or
other changes or additions thereto or deletions  therefrom as may be required by
ordinary usage, custom or practice and such legends or endorsements  required by
law, stock  exchange rule and  agreements to which the Trust is subject,  if any
(provided that any such notation,  legend or endorsement is in a form acceptable
to the Trust).  The Trust at the direction of the Sponsor shall furnish any such
legend not  contained  in Exhibit A-1 to the  Institutional  Trustee in writing.
Each Convertible  Preferred Security  Certificate shall be dated the date of its
authentication.  The terms and provisions of the Securities set forth in Annex I
and the forms of  Securities  set forth in Exhibits  A-1 and A-2 are part of the
terms of this  Declaration  and,  to the extent  applicable,  the  Institutional
Trustee and the Sponsor,  by their  execution and delivery of this  Declaration,
expressly agree to such terms and provisions and to be bound thereby.

     SECTION 7.4. PAYING AGENT.

     The Trust shall  maintain in the  Borough of  Manhattan,  City of New York,
State of New York, an office or agency where  Convertible  Preferred  Securities
not held in book-entry only form may be presented for payment ("PAYING  Agent").
The Trust shall  maintain an office or agency where  Securities may be presented
for conversion  ("CONVERSION AGENT"). The Trust may appoint the Paying Agent and
the Conversion  Agent and may appoint one or more  additional  paying agents and
one or more  additional  conversion  agents in such other  locations as it shall
determine.  The term "Paying Agent" includes any additional paying agent and the
term "Conversion Agent" includes any additional  conversion agent. The Trust may


                                       35
<PAGE>

change any Paying Agent or Conversion  Agent without prior notice to any Holder.
The Trust  shall  notify  the  Institutional  Trustee in writing of the name and
address  of any Agent  not a party to this  Declaration.  If the Trust  fails to
appoint or maintain  another  entity as Paying Agent or  Conversion  Agent,  the
Institutional  Trustee shall act as such. The Trust or any of its Affiliates may
act as Paying Agent or Conversion Agent. The Trust shall act as Paying Agent and
Conversion Agent for the Common Securities.

     The Trust  initially  appoints  The Bank of New York,  101 Barclay  Street,
Floor  21  West,  New  York,  New  York  10286,   Attention:   Corporate   Trust
Administration,  as  Paying  Agent  and  Conversion  Agent  for the  Convertible
Preferred Securities.

     SECTION 7.5. CUSIP NUMBERS

     The Company in issuing  the  Securities  may use  "CUSIP"  numbers (if then
generally in use),  and, if so, the Trustee shall use "CUSIP" numbers in notices
of  redemption as a  convenience  to Holders;  PROVIDED that any such notice may
state  that no  representation  is made as to the  correctness  of such  numbers
either  as  printed  on  the  Securities  or as  contained  in any  notice  of a
redemption  and that  reliance  may be placed  only on the other  identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.  The Company will promptly  notify
the Trustee of any change in the "CUSIP" numbers.

                                  ARTICLE VIII

                                       36
<PAGE>

          (v) upon the occurrence and  continuation  of a Special Event pursuant
     to which the Trust shall have been  dissolved in accordance  with the terms
     of the  Securities  and all of the  Debentures  held  by the  Institutional
     Trustee  shall  have been  distributed  to the  Holders  of  Securities  in
     exchange for all of the Securities;

          (vi) upon the written direction to the Institutional  Trustee from the
     Sponsor  at any time to  dissolve  the Trust  and,  after  satisfaction  of
     liabilities  to creditors of the Trust as provided by  applicable  law, the
     distribution of Debentures  having an aggregate  principal  amount equal to
     the  aggregate  stated  liquidation  amount  of the  Convertible  Preferred
     Securities  and the Common  Securities  to the  Holders of the  Convertible
     Preferred  Securities  and the Common  Securities  in  liquidation  of such
     Holders'  interests in the Trust,  subject to the Regular Trustees' receipt
     of an opinion of nationally  recognized  independent counsel experienced in
     such matters to the effect that the Holders will not  recognize any income,
     gain or loss for United States  federal  income tax purposes as a result of
     the  dissolution  of  the  Trust  and  such   distribution  to  Holders  of
     Convertible Preferred Securities;

          (vii)  upon the  distribution  of the  Sponsor's  Common  Stock to all
     Holders  of  Convertible   Preferred  Securities  upon  conversion  of  all
     outstanding Convertible Preferred Securities;

          (viii) the expiration of the term of the Trust on April 15, 2035; or

          (ix) before the issuance of any Securities, with the consent of all of
     the Regular Trustees and the Sponsor.

     (b) As soon as is practicable  after the occurrence of an event referred to
in Section 8.1(a) and after liquidation of the assets of the Trust in accordance
with  applicable  law,  the  Regular   Trustees  shall  file  a  certificate  of
cancellation with the Secretary of State of the State of Delaware.

     (c) The provisions of Sections 3.9 and 3.10 and Article X shall survive the
termination of the Trust.

                                   ARTICLE IX

                              TRANSFER OF INTERESTS

     SECTION 9.1. TRANSFER OF SECURITIES.

     (a) Securities may only be transferred,  in whole or in part, in accordance
with the terms and conditions set forth in this  Declaration and in the terms of
the  Securities.  To the  fullest  extent  permitted  by law,  any  transfer  or
purported  transfer of any Security not made in accordance with this Declaration
shall be null and void.



                                       37
<PAGE>

     (b) Subject to this Article IX, Convertible  Preferred  Securities shall be
transferable.

     (c) Subject to this Article IX, the Sponsor and any Related  Party may only
transfer Common  Securities (i) to the Sponsor or a Related Party of the Sponsor
or (ii) to a Person in  accordance  with Article IX of the  Indenture;  provided
that,  any  such  transfer  is  subject  to the  condition  precedent  that  the
transferor  obtain the  written  opinion of  nationally  recognized  independent
counsel experienced in such matters that such transfer would not cause more than
an insubstantial risk that:

          (i) the Trust would not be classified for United States federal income
     tax purposes as a grantor trust; and

          (ii) the Trust  would be an  Investment  Company  required to register
     under  the  Investment  Company  Act  or the  transferee  would  become  an
     Investment Company required to register under the Investment Company Act.

     (d) Each Security that bears or is required to bear the legend set forth in
this  Section  9.1(d)  (a  "RESTRICTED   SECURITY")  shall  be  subject  to  the
restrictions  on  transfer  provided  in the  legend  set forth in this  Section
9.1(d),  unless such  restrictions  on  transfer  shall be waived by the written
consent of the Regular Trustees,  and the Holder of each Restricted Security, by
such   securityholder's   acceptance  thereof,   agrees  to  be  bound  by  such
restrictions on transfer.  As used in this Section 9.1(d) and in Section 9.1(e),
the term "transfer" encompasses any sale, pledge,  transfer or other disposition
of any Restricted Security.

     Prior  to  the  Transfer  Restriction  Termination  Date,  any  certificate
evidencing a Security shall bear a legend in  substantially  the following form,
unless  otherwise agreed by the Regular Trustees (with written notice thereof to
the Institutional Trustee):

     THE  SECURITY  EVIDENCED  HEREBY  HAS NOT BEEN  REGISTERED  UNDER  THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY
NOT BE OFFERED OR SOLD  WITHIN  THE UNITED  STATES OR TO, OR FOR THE  ACCOUNT OR
BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING  SENTENCE.  BY ITS
ACQUISITION   HEREOF,  THE  HOLDER  (1)  REPRESENTS  THAT  IT  IS  A  "QUALIFIED
INSTITUTIONAL  BUYER" (AS DEFINED IN RULE 144A UNDER THE  SECURITIES  ACT),  (2)
AGREES THAT IT WILL NOT PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE
TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES
ACT (OR ANY  SUCCESSOR  PROVISION)  RESELL OR  OTHERWISE  TRANSFER  THE SECURITY
EVIDENCED  HEREBY OR THE COMMON STOCK,  ISSUABLE UPON  CONVERSION OR EXCHANGE OF
THIS  SECURITY  EXCEPT (A) TO VIATEL,  INC. (THE  "COMPANY")  OR ANY  SUBSIDIARY
THEREOF,  (B)  PURSUANT  TO  AN  EFFECTIVE   REGISTRATION  STATEMENT  UNDER  THE
SECURITIES ACT, (C) TO A QUALIFIED  INSTITUTIONAL  BUYER IN COMPLIANCE WITH RULE
144A UNDER THE SECURITIES ACT, (D) TO AN "INSTITUTIONAL ACCREDITED INVESTOR" (AS
DEFINED IN RULE 501(A)(1),  (2)(3) OR (7) UNDER THE SECURITIES ACT) THAT,  PRIOR


                                       38
<PAGE>

TO  SUCH  TRANSFER,  FURNISHES  TO THE  TRUSTEE  FOR THE  CONVERTIBLE  PREFERRED
SECURITIES  OR THE  CONVERTIBLE  DEBENTURES,  AS THE  CASE  MAY BE (OR,  IF THIS
CERTIFICATE  EVIDENCES COMMON STOCK, THE TRANSFER AGENT FOR THE COMMON STOCK), A
SIGNED LETTER CONTAINING CERTAIN  REPRESENTATIONS AND AGREEMENTS RELATING TO THE
RESTRICTIONS  ON TRANSFER OF THE  SECURITY  EVIDENCED  HEREBY (THE FORM OF WHICH
LETTER CAN BE OBTAINED  FROM SUCH  TRUSTEE OR TRANSFER  AGENT),  (E) OUTSIDE THE
UNITED  STATES IN  COMPLIANCE  WITH RULE 904  UNDER  THE  SECURITIES  ACT OR (F)
PURSUANT  TO THE  EXEMPTION  FROM  REGISTRATION  PROVIDED  BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE) AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
TO WHOM THE SECURITY  EVIDENCED HEREBY IS TRANSFERRED A NOTICE  SUBSTANTIALLY TO
THE EFFECT OF THIS  LEGEND.  IN  CONNECTION  WITH ANY  TRANSFER OF THE  SECURITY
EVIDENCED  HEREBY PRIOR TO THE  EXPIRATION OF THE HOLDING  PERIOD  APPLICABLE TO
SALES OF THE SECURITY  EVIDENCED  HEREBY UNDER RULE 144(K) UNDER THE  SECURITIES
ACT (OR ANY SUCCESSOR PROVISION),  THE HOLDER MUST CHECK THE APPROPRIATE BOX SET
FORTH ON THE REVERSE  HEREOF  RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT
THIS CERTIFICATE TO THE TRUSTEE FOR THE CONVERTIBLE  PREFERRED SECURITIES OR THE
CONVERTIBLE  DEBENTURES,  AS THE CASE MAY BE (OR, IF THIS CERTIFICATE  EVIDENCES
COMMON   STOCK,   SUCH  HOLDER  MUST   FURNISH  TO  THE   TRANSFER   AGENT  SUCH
CERTIFICATIONS,  LEGAL  OPINIONS OR OTHER  INFORMATION  AS THE COMPANY OR VIATEL
FINANCING  TRUST I ("THE  TRUST") MAY  REASONABLY  REQUIRE TO CONFIRM  THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION  FROM, OR IN A TRANSACTIONS  NOT
SUBJECT  TO, THE  REGISTRATION  REQUIREMENTS  OF THE  SECURITIES  ACT).  IF THIS
CERTIFICATE DOES NOT EVIDENCE COMMON STOCK AND IF THE PROPOSED  TRANSFEREE IS AN
INSTITUTIONAL  ACCREDITED  INVESTOR OR A PURCHASER WHO IS NOT A U.S. PERSON, THE
HOLDER MUST, PRIOR TO SUCH TRANSFER,  FURNISH TO THE TRUSTEE FOR THE CONVERTIBLE
PREFERRED  SECURITIES OR THE  CONVERTIBLE  DEBENTURES,  AS THE CASE MAY BE, SUCH
CERTIFICATIONS,  LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY OR THE TRUST
MAY  REASONABLY  REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO
AN  EXEMPTION  FROM,  OR IN A  TRANSACTION  NOT  SUBJECT  TO,  THE  REGISTRATION
REQUIREMENTS  OF THE  SECURITIES  ACT.  THIS  LEGEND  WILL BE REMOVED  AFTER THE
EXPIRATION OF THE HOLDING PERIOD  APPLICABLE TO SALES OF THE SECURITY  EVIDENCED

HEREBY UNDER RULE 144(K)  UNDER THE  SECURITIES  ACT. AS USED HEREIN,  THE TERMS
"OFFSHORE  TRANSACTION,"  "UNITED  STATES" AND "U.S.  PERSON"  HAVE THE MEANINGS
GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

     Following  the  Transfer  Restriction  Termination  Date,  any  Security or
security issued in exchange or substitution  therefor (other than (i) Securities
acquired  by Viatel or any  Affiliate  and (ii)  Common  Stock  issued  upon the
conversion  or exchange of any Security  described in clause (i) above) may upon
surrender of such Security for exchange to any Regular  Trustee on behalf of the
Trust in accordance  with the  provisions of Section 9.2, be exchanged for a new
Security or Securities,  of like tenor and aggregate  liquidation amount,  which
shall not bear the restrictive legend required by this Section 9.1(d).

     Any  Convertible  Preferred  Security  or  Common  Stock  issued  upon  the
conversion or exchange of a Convertible  Preferred  Security that,  prior to the
Transfer  Restriction  Termination  Date, is purchased or owned by Viatel or any
Affiliate  thereof  may  not be  resold  by  Viatel  or  such  Affiliate  unless
registered  under the Securities Act or resold pursuant to an exemption from the
registration  requirements of the Securities Act in a transaction  which results
in such Convertible Preferred Securities or Common Stock, as the case may be, no
longer being "restricted securities" (as defined under Rule 144).

     SECTION 9.2. TRANSFER OF CERTIFICATES.

     The Regular Trustees shall provide for the registration of Certificates and
of transfers of Certificates,  which will be effected  without charge,  but only
upon  payment  in  respect of any tax or other  government  charges  that may be
imposed in relation to it. Upon  surrender for  registration  of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to be
issued  in  the  name  of  the  designated  transferee  or  transferees.   Every
Certificate  surrendered for  registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees duly
executed by the Holder or such  Holder's  attorney  duly  authorized in writing.
Each  Certificate  surrendered for registration of transfer shall be canceled by
the Regular  Trustees.  A transferee of a  Certificate  shall be entitled to the
rights and subject to the obligations of a Holder  hereunder upon the receipt by
such  transferee  of  a  Certificate.  By  acceptance  of  a  Certificate,  each
transferee shall be deemed to have agreed to be bound by this Declaration.

     SECTION 9.3. DEEMED SECURITY HOLDERS.

     The  Trustees may treat the Person in whose name any  Certificate  shall be
registered  on the books  and  records  of the Trust as the sole  holder of such
Certificate and of the Securities  represented by such  Certificate for purposes
of  receiving   Distributions  and  for  all  other  purposes   whatsoever  and,
accordingly,  shall not be bound to recognize any equitable or other claim to or
interest  in  such  Certificate  or  in  the  Securities   represented  by  such

actual or other notice thereof.

     SECTION 9.4. BOOK ENTRY INTERESTS.

     (a) So long as Convertible Preferred Securities are eligible for book-entry
settlement  with the Clearing  Agency or unless  otherwise  required by law, all
Convertible  Preferred Securities that are so eligible may be represented by one
or more fully registered  Convertible  Preferred  Security  Certificates (each a
"GLOBAL  CERTIFICATE")  in  global  form to be  delivered  to DTC,  the  initial
Clearing Agency, by, or on behalf of, the Trust. Such Global  Certificates shall
initially  be  registered  on the books and  records of the Trust in the name of
Cede & Co., the nominee of DTC, and no Convertible Preferred Security Beneficial
Owner will  receive a  definitive  Convertible  Preferred  Security  Certificate
representing such Convertible Preferred Security Beneficial Owner's interests in
such Global Certificates,  except as provided in Section 9.7 below. The transfer
and exchange of  beneficial  interests in any such Security in global form shall
be effected  through the Clearing Agency in accordance with this Declaration and
the procedures of the Clearing Agency therefor.

     (b)  Convertible  Preferred  Securities  that  upon  initial  issuance  are
beneficially  owned by QIBs may, at the option of the Trust,  be  represented by
one or more Global Certificates (a "144A GLOBAL SECURITY").

     Except as provided  below,  beneficial  owners of a  Convertible  Preferred
Security in global form shall not be entitled to have certificates registered in
their  names,  will not receive or be entitled to receive  physical  delivery of
certificates  in  definitive  form and will not be  considered  Holders  of such
Convertible Preferred Security in global form.

     (c) So  long as the  Convertible  Preferred  Securities  are  eligible  for
book-entry settlement and to the extent Convertible Preferred Securities held by
QIBs, are held in a global form, or unless  otherwise  required by law, upon any
transfer of a definitive  Convertible  Preferred Security to a QIB in accordance
with Rule 144A, unless otherwise  requested by the transferor,  and upon receipt
of the  definitive  Convertible  Preferred  Security  or  Convertible  Preferred
Securities  being  so  transferred,  together  with  a  certification  from  the
transferor  that the  transfer  is being made in  compliance  with Rule 144A (or
other  evidence  satisfactory  to the  Institutional  Trustee  on  behalf of the
Trust),  the  Institutional  Trustee  on  behalf  of the  Trust  shall  make  an
endorsement on any 144A Global  Security to reflect an increase in the number of
Convertible Preferred Securities represented by such Global Certificate, and the
Institutional  Trustee  on behalf  of the Trust  shall  cancel  such  definitive
Convertible Preferred Security or Convertible Preferred Securities in accordance
with the standing instructions and procedures of the Clearing Agency, the number
of Convertible  Preferred Securities  represented by such Convertible  Preferred
Security in global form to be increased accordingly; provided that no definitive
Convertible  Preferred  Security,  or portion  thereof,  in respect of which the
Trust or an  Affiliate  of the  Trust  held  any  beneficial  interest  shall be
included  in such  Convertible  Preferred  Security  in global  form  until such
definitive Convertible Preferred Security is freely tradeable in accordance with
Rule 144(k);  provided further that the Trust shall issue Convertible  Preferred
Securities in definitive form upon any transfer of a beneficial  interest in the


                                       41
<PAGE>

Convertible Preferred Security in global form to the Company or any Affiliate of
the Company.

     (d) Any Global Certificate may be endorsed with or have incorporated in the
text  thereof  such  legends or recitals or changes  not  inconsistent  with the
provisions of this Declaration as may be required by the Clearing Agency, by any
national  securities  exchange  or by the  National  Association  of  Securities
Dealers,  Inc. in order for the Convertible Preferred Securities to be tradeable
on the  PORTAL  Market  or as may be  required  for  the  Convertible  Preferred
Securities  to be  tradeable  on any  other  market  developed  for  trading  of
securities  pursuant to Rule 144A or required to comply with any  applicable law
or any regulation thereunder or with the rules and regulations of any securities
exchange upon which the Convertible Preferred Securities may be listed or traded
or to conform  with any usage with respect  thereto,  or to indicate any special
limitations  or  restrictions  to which  any  particular  Convertible  Preferred
Securities are subject.

     (e) Unless and until  definitive,  fully registered  Convertible  Preferred
Security   Certificates   (the  "DEFINITIVE   CONVERTIBLE   PREFERRED   SECURITY
CERTIFICATES") have been issued to the Convertible Preferred Security Beneficial
Owners of a  Convertible  Preferred  Security in global form pursuant to Section
9.7:

          (i) the  provisions  of this  Section  9.4 shall be in full  force and
     effect with respect to such Convertible Preferred Securities;

          (ii) the Trust and the  Trustees  shall be  entitled  to deal with the
     Clearing Agency for all purposes of this Declaration (including the payment
     of Distributions on the Global Certificates and receiving approvals,  votes
     or  consents  hereunder)  as  the  Holder  of  such  Convertible  Preferred
     Securities and the sole holder of the Global Certificates and shall have no
     obligation to the Convertible  Preferred Security Beneficial Owners of such
     Convertible Preferred Securities;

          (iii) to the extent that the  provisions  of this Section 9.4 conflict
     with any other  provisions  of this  Declaration,  the  provisions  of this
     Section 9.4 shall control; and

          (iv) the  rights  of the  Convertible  Preferred  Security  Beneficial
     Owners  of  Convertible  Preferred  Securities  in  global  form  shall  be
     exercised  only through the  Clearing  Agency and shall be limited to those
     established  by law  and  agreements  between  such  Convertible  Preferred
     Security  Beneficial  Owners and the  Clearing  Agency  and/or the Clearing
     Agency  Participants.  The Clearing Agency will make  book-entry  transfers
     among Clearing  Agency  Participants  and receive and transmit  payments of
     Distributions   on  the  Global   Certificates   to  such  Clearing  Agency
     Participants.  DTC will make book entry transfers among the Clearing Agency
     Participants provided,  that solely for the purposes of determining whether
     the Holders of the requisite  amount of  Convertible  Preferred  Securities


                                       42
<PAGE>

     have  voted on any  matter  provided  for in this  Declaration,  so long as
     Definitive  Convertible  Preferred  Security  Certificates  have  not  been
     issued,  the Trustees may  conclusively  rely on, and shall be protected in
     relying on, any written  instrument  (including  a proxy)  delivered to the
     Trustees by the Clearing  Agency  setting forth the  Convertible  Preferred
     Securities  Beneficial  Owners' votes or assigning the right to vote on any
     matter to any other Persons either in whole or in part.

     (f)  Notwithstanding  any other provisions of this Declaration  (other than
the  provisions  set forth in this  Section  9.4(f)),  a  Convertible  Preferred
Security in global form may not be transferred as a whole except by the Clearing
Agency to a nominee  of the  Clearing  Agency  or by a nominee  of the  Clearing
Agency to the Clearing Agency or another nominee to a successor  Clearing Agency
or a nominee of such successor Clearing Agency.

     SECTION 9.5. NOTICES TO CLEARING AGENCY.

     Whenever  a notice  or other  communication  to the  Convertible  Preferred
Security Holders is required under this Declaration, unless and until Definitive
Convertible  Preferred  Security  Certificates  shall  have  been  issued to the
Convertible  Preferred  Security  Beneficial Owners pursuant to Section 9.7, the
Regular Trustees shall give all such notices and communications specified herein
to be  given to the  Convertible  Preferred  Security  Holders  to the  Clearing
Agency,  and  shall  have no notice  obligations  to the  Convertible  Preferred
Security Beneficial Owners.

     SECTION 9.6. APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

     If any Clearing Agency notifies the Trust that it is unwilling or unable to
continue its services as securities  depositary  with respect to the Convertible
Preferred  Securities,  if such Clearing Agency ceases to perform such services,
or if at any time such Clearing Agency ceases to be a clearing agency registered
as such under the  Exchange Act when such  Clearing  Agency is required to be so
registered to act as such  depositary,  then the Regular  Trustees may, in their
sole  discretion,  appoint a  successor  Clearing  Agency  with  respect to such
Convertible Preferred Securities.

     SECTION 9.7. DEFINITIVE  CONVERTIBLE  PREFERRED SECURITY CERTIFICATES UNDER
CERTAIN CIRCUMSTANCES.

     If:

          (a) a  Clearing  Agency  notifies  the Trust that it is  unwilling  or
     unable to continue its services as  securities  depositary  with respect to
     the Convertible Preferred  Securities,  if at any time such Clearing Agency
     ceases to be a clearing  agency  registered  as such under the Exchange Act
     when such  Clearing  Agency is required to be so  registered to act as such
     depositary  and no  successor  Clearing  Agency  shall have been  appointed
     pursuant to Section 9.6 within 90 days of such notification;



                                       43
<PAGE>

          (b) the Regular  Trustees (with the consent of the Sponsor),  in their
     sole  discretion  determine that the  Convertible  Preferred  Securities in
     global  from shall be  exchanged  for  certificated  Convertible  Preferred
     Securities; or

          (c) there shall have occurred and be continuing an Event of Default;

     then:

          (d) Definitive  Convertible  Preferred Security  Certificates shall be
     prepared  by the Regular  Trustees  on behalf of the Trust with  respect to
     such Convertible Preferred Securities; and

          (e) upon surrender of the Global  Certificates by the Clearing Agency,
     accompanied by registration instructions,  the Regular Trustees shall cause
     Definitive  Convertible  Preferred Security Certificates to be delivered to
     Convertible  Preferred  Security  Beneficial  Owners  of  such  Convertible
     Preferred  Securities in accordance  with the  instructions of the Clearing
     Agency.

Neither the  Trustees nor the Trust shall be liable for any delay in delivery of
such  instructions  and  each of them  may  conclusively  rely on and  shall  be
protected  in  relying  on,  said  instructions  of  the  Clearing  Agency.  The
Definitive   Convertible  Preferred  Security  Certificates  shall  be  printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters,  numbers or other marks of  identification or designation
and such legends or endorsements as the Regular  Trustees may deem  appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant  thereto or with any rule or regulation of any stock  exchange on which
Convertible Preferred Securities may be listed, or to conform to usage.

     At such time as all interests in a Convertible Preferred Security in global
form have been redeemed,  converted,  exchanged,  repurchased or canceled,  such
Convertible  Preferred  Security in global form shall be, upon receipt  thereof,
canceled by the Trust in accordance with standing procedures and instructions of
the Clearing Agency.

     Convertible   Preferred   Securities   that  upon   initial   issuance  are
beneficially owned by persons that are neither QIBs nor Non-U.S. Persons will be
issued as Definitive  Convertible Preferred Security Certificates and may not be
represented by a Global Certificate.  Convertible Preferred Securities that upon
initial  issuance are  beneficially  owned by persons that are Non-U.S.  Persons
may, at the option of the Trust, be issued as Definitive  Convertible  Preferred
Security Certificates.

     SECTION 9.8. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

     If:



                                       44
<PAGE>

          (a) any mutilated  Certificates  should be  surrendered to the Regular
     Trustees,  or if the  Regular  Trustees  shall  receive  evidence  to their
     satisfaction of the destruction, loss or theft of any Certificate; and

          (b) there  shall be  delivered  to the  Institutional  Trustee  or the
     Regular  Trustees  such security or indemnity as may be required by them to
     keep each of them harmless,

     then:

in the absence of notice  that such  Certificate  shall have been  acquired by a
bona fide purchaser,  the Institutional Trustee or any Regular Trustee on behalf
of the Trust shall execute and deliver, in exchange for, or in lieu of, any such
mutilated,  destroyed,  lost or stolen  Certificate,  a new  Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.8, the  Institutional  Trustee or the Regular Trustees may require the
payment of a sum sufficient to cover any tax or other  governmental  charge that
may be  imposed  in  connection  therewith.  Any  duplicate  Certificate  issued
pursuant to this Section shall  constitute  conclusive  evidence of an ownership
interest in the relevant Securities, as if originally issued, whether or not the
lost, stolen or destroyed Certificate shall be found at any time.

              LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES,
                               TRUSTEES OR OTHERS

     SECTION 10.1. LIABILITY.

     (a)  Except as  expressly  set forth in this  Declaration,  the  Securities
Guarantees and the terms of the Securities, the Sponsor shall not be:

          (i)  personally  liable for the return of any  portion of the  capital
     contributions  (or any return  thereon)  of the  Holders of the  Securities
     which shall be made solely from assets of the Trust; or

          (ii) be  required  to pay to the Trust or to any Holder of  Securities
     any deficit upon dissolution of the Trust or otherwise.

     (b) The  Holder of the  Common  Securities  shall be liable  for all of the
debts and  obligations of the Trust (other than with respect to the  Securities)
to the extent not satisfied out of the Trust's assets.



                                       45
<PAGE>

     (c) Pursuant to Section  3803(a) of the Business  Trust Act, the Holders of
the Convertible Preferred Securities shall be entitled to the same limitation of
personal liability  extended to stockholders of private  corporations for profit
organized under the General Corporation Law of the State of Delaware.

     SECTION 10.2. EXCULPATION.

     (a) No  Indemnified  Person shall be liable,  responsible or accountable in
damages or otherwise to the Trust or any Covered Person for any loss, liability,
expense,  damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority  conferred on such  Indemnified  Person by this Declaration or by law,
except that an Indemnified  Person shall be liable for any such loss,  damage or
claim  incurred  by reason of such  Indemnified  Person's  gross  negligence  or
willful misconduct with respect to such acts or omissions.

     (b) An Indemnified Person shall be fully protected in relying in good faith
upon the records of the Trust and upon such  information,  opinions,  reports or
statements  presented  to the Trust by any Person as to matters the  Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust,  including information,  opinions,  reports or statements as to the value
and amount of the  assets,  liabilities,  profits,  losses,  or any other  facts
pertinent  to the  existence  and amount of assets from which  Distributions  to
Holders of Securities might properly be paid.

     SECTION 10.3. FIDUCIARY DUTY.

     (a) To the extent  that,  at law or in equity,  an  Indemnified  Person has
duties  (including  fiduciary  duties) and liabilities  relating  thereto to the
Trust or to any other Covered  Person,  an Indemnified  Person acting under this
Declaration  shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration. The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an  Indemnified  Person  otherwise  existing at law or in equity (other than the
duties imposed on the Institutional  Trustee under the Trust Indenture Act), are
agreed by the parties  hereto to replace  such other duties and  liabilities  of
such Indemnified Person.

     (b) Unless otherwise expressly provided herein:

          (i)  whenever a conflict  of  interest  exists or arises  between  any
     Covered Persons and any Indemnified Persons; or

          (ii) whenever this  Declaration  or any other  agreement  contemplated
     herein or therein provides that an Indemnified Person shall act in a manner


                                       46
<PAGE>

     that is, or provides  terms that are,  fair and  reasonable to the Trust or
     any Holder of Securities;

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms,  considering  in each case the relative  interest of each
party (including its own interest) to such conflict,  agreement,  transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the  resolution,  action or term so made,  taken or provided by the  Indemnified
Person shall not constitute a breach of this  Declaration or any other agreement
contemplated  herein or of any duty or obligation of the  Indemnified  Person at
law or in equity or otherwise.

     (c)  Whenever in this  Declaration  an  Indemnified  Person is permitted or
required to make a decision:

          (i) in its  "discretion"  or under a grant of similar  authority,  the
     Indemnified Person shall be entitled to consider such interests and factors
     as it  desires,  including  its own  interests,  and shall  have no duty or
     obligation  to  give  any  consideration  to  any  interest  of or  factors
     affecting the Trust or any other Person; or

          (ii) in its  "good  faith"  or under  another  express  standard,  the
     Indemnified  Person shall act under such express  standard and shall not be
     subject to any other or different  standard  imposed by this Declaration or
     by applicable law.

      SECTION 10.4.  INDEMNIFICATION.

     (a) (i) The Debenture Issuer shall indemnify,  to the full extent permitted
by law, any Company Indemnified Person who was or is a party or is threatened to
be  made a  party  to any  threatened,  pending  or  completed  action,  suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action  by or in the right of the  Trust) by reason of the fact that he is or
was a Company Indemnified Person against expenses (including attorneys' fees and
expenses),  judgments,  fines  and  amounts  paid  in  settlement  actually  and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he  reasonably  believed  to be in or not
opposed to the best  interests of the Trust,  and,  with respect to any criminal
action or  proceeding,  had no  reasonable  cause to  believe  his  conduct  was
unlawful. The termination of any action, suit or proceeding by judgment,  order,
settlement,  conviction,  or upon a plea of nolo  contendere or its  equivalent,
shall not, of itself,  create a presumption that the Company  Indemnified Person
did not act in good faith and in a manner which he reasonably  believed to be in
or not opposed to the best  interests  of the Trust,  and,  with  respect to any
criminal  action or  proceeding,  had no  reasonable  cause to believe  that his
conduct was unlawful.



                                       47
<PAGE>

     (ii) The Debenture Issuer shall indemnify,  to the full extent permitted by
law, any Company Indemnified Person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action or suit by or in the
right of the Trust to procure a judgment in its favor by reason of the fact that
he is or was a Company Indemnified Person against expenses (including attorneys'
fees and expenses)  actually and reasonably  incurred by him in connection  with
the defense or  settlement  of such action or suit if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Trust and except that no such indemnification shall be made in respect of
any claim,  issue or matter as to which such  Company  Indemnified  Person shall
have been  adjudged to be liable to the Trust unless and only to the extent that
the Court of  Chancery of Delaware or the court in which such action or suit was
brought shall  determine upon  application  that,  despite the  adjudication  of
liability  but in view of all the  circumstances  of the  case,  such  person is
fairly and  reasonably  entitled to indemnity for such expenses which such Court
of Chancery or such other court shall deem proper.

     (iii) To the extent that a Company  Indemnified  Person shall be successful
on the merits or otherwise  (including  dismissal of an action without prejudice
or the settlement of an action without admission of liability) in defense of any
action,  suit or  proceeding  referred  to in  paragraphs  (i) and  (ii) of this
Section 10.4(a),  or in defense of any claim, issue or matter therein,  he shall
be indemnified, to the full extent permitted by law, against expenses (including
attorneys'  fees  and  expenses)  actually  and  reasonably  incurred  by him in
connection therewith.

     (iv) Any  indemnification  under  paragraphs  (i) and (ii) of this  Section
10.4(a) (unless  ordered by a court) shall be made by the Debenture  Issuer only
as authorized in the specific case upon a determination that  indemnification of
the Company Indemnified Person is proper in the circumstances because he has met
the  applicable  standard of conduct set forth in paragraphs  (i) or (ii).  Such
determination  shall be made (1) by the Regular Trustees by a majority vote of a
quorum  consisting of such Regular Trustees who were not parties to such action,
suit  or  proceeding,  (2) if  such a  quorum  is not  obtainable,  or,  even if
obtainable,  if a quorum  of  disinterested  Regular  Trustees  so  directs,  by
independent  legal counsel in a written  opinion,  or (3) by the Common Security
Holder of the Trust.

     (v) Expenses (including attorneys' fees and expenses) incurred by a Company
Indemnified   Person  in  defending  a  civil,   criminal,   administrative   or
investigative  action, suit or proceeding referred to in paragraphs (i) and (ii)
of this Section 10.4(a) shall be paid by the Debenture  Issuer in advance of the
final  disposition  of  such  action,  suit or  proceeding  upon  receipt  of an
undertaking  by or on behalf of such  Company  Indemnified  Person to repay such
amount  if it shall  ultimately  be  determined  that he is not  entitled  to be
indemnified  by the  Debenture  Issuer as  authorized  in this Section  10.4(a).
Notwithstanding the foregoing,  no advance shall be made by the Debenture Issuer
if a determination  is reasonably and promptly made (i) by the Regular  Trustees
by a majority vote of a quorum of disinterested Regular Trustees, (ii) if such a
quorum is not obtainable,  or, even if obtainable,  if a quorum of disinterested
Regular Trustees so directs,  by independent  legal counsel in a written opinion
or (iii) by the Common Security Holder of the Trust,  that, based upon the facts
known to the Regular Trustees, counsel or the Common Security Holder at the time


                                       48
<PAGE>

such  determination is made, such Company  Indemnified Person acted in bad faith
or in a manner  that such  person did not believe to be in or not opposed to the
best interests of the Trust, or, with respect to any criminal  proceeding,  that
such Company  Indemnified Person believed or had reasonable cause to believe his
conduct was unlawful.  In no event shall any advance be made in instances  where
the  Regular  Trustees,  independent  legal  counsel or Common  Security  Holder
reasonably  determine  that such person  deliberately  breached  his duty to the
Trust or its Common or Convertible Preferred Security Holders.

     (vi) The  indemnification  and  advancement  of  expenses  provided  by, or
granted  pursuant to, the other  paragraphs of this Section 10.4(a) shall not be
deemed exclusive of any other rights to which those seeking  indemnification and
advancement  of  expenses  may  be  entitled   under  any  agreement,   vote  of
stockholders or  disinterested  directors of the Debenture Issuer or Convertible
Preferred  Security Holders of the Trust or otherwise,  both as to action in his
official  capacity  and as to action in  another  capacity  while  holding  such
office. All rights to indemnification under this Section 10.4(a) shall be deemed
to be  provided  by a contract  between the  Debenture  Issuer and each  Company
Indemnified  Person who serves in such  capacity at any time while this  Section
10.4(a) is in effect.  Any repeal or  modification of this Section 10.4(a) shall
not affect any rights or obligations then existing.

     (vii) The Debenture Issuer or the Trust may purchase and maintain insurance
on behalf of any person who is or was a Company  Indemnified  Person against any
liability  asserted  against him and  incurred by him in any such  capacity,  or
arising out of his status as such,  whether or not the  Debenture  Issuer  would
have the power to indemnify him against such  liability  under the provisions of
this Section 10.4(a).

     (viii) For  purposes of this  Section  10.4(a),  references  to "the Trust"
shall include, in addition to the resulting or surviving entity, any constituent
entity (including any constituent of a constituent)  absorbed in a consolidation
or  merger,  so that any person who is or was a  director,  trustee,  officer or
employee of such constituent entity, or is or was serving at the request of such
constituent entity as a director, trustee, officer, employee or agent of another
entity,  shall stand in the same position  under the  provisions of this Section
10.4(a) with respect to the resulting or surviving  entity as he would have with
respect to such constituent entity if its separate existence had continued.

     (ix) The  indemnification  and  advancement  of  expenses  provided  by, or
granted pursuant to, this Section 10.4(a) shall,  unless otherwise provided when
authorized  or ratified,  continue as to a person who has ceased to be a Company
Indemnified  Person and shall inure to the benefit of the heirs,  executors  and
administrators of such a person.

     (b) The Debenture  Issuer agrees to fully  indemnify the (i)  Institutional
Trustee,  (ii) the Delaware  Trustee,  (iii) any Affiliate of the  Institutional
Trustee  and  the  Delaware   Trustee,   and  (iv)  any   officers,   directors,
shareholders,   members,  partners,  employees,   representatives,   custodians,
nominees or agents of the  Institutional  Trustee and the Delaware Trustee (each
of the Persons in (i) through (iv) being referred to as a "FIDUCIARY INDEMNIFIED


                                       49
<PAGE>

PERSON") for, and to hold each Fiduciary  Indemnified  Person harmless  against,
any  and  all  loss,  liability,  claim,  damage  or  expense  incurred  without
negligence or bad faith on its part,  arising out of or in  connection  with the
acceptance or  administration  or the trust or trusts  hereunder,  including the
costs and expenses  (including  reasonable legal fees and expenses) of defending
itself against or  investigating  any claim or liability in connection  with the
exercise or performance of any of its powers or duties hereunder. The provisions
of this Section  10.4(b)  shall survive the  satisfaction  and discharge of this
Declaration or the  resignation or removal of the  Institutional  Trustee or the
Delaware Trustee, as the case may be.

     SECTION 10.5. OUTSIDE BUSINESS.

     Any Covered Person, the Sponsor, the Delaware Trustee and the Institutional
Trustee  (subject  to Section  5.3(c))  may engage in or possess an  interest in
other  business  ventures of any nature or  description,  independently  or with
others,  similar or dissimilar  to the business of the Trust,  and the Trust and
the Holders of Securities  shall have no rights by virtue of this Declaration in
and to such independent ventures or the income or profits derived therefrom, and
the pursuit of any such venture,  even if  competitive  with the business of the
Trust, shall not be deemed wrongful or improper. No Covered Person, the Sponsor,
the Delaware Trustee, or the Institutional Trustee shall be obligated to present
any  particular  investment  or  other  opportunity  to the  Trust  even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the  Trust,  and any  Covered  Person,  shall have the right to take for its own
account  (individually  or as a partner or  fiduciary) or to recommend to others
any such particular  investment or other  opportunity.  Any Covered Person,  the
Delaware  Trustee and the  Institutional  Trustee may engage or be interested in
any  financial  or other  transaction  with the Sponsor or any  Affiliate of the
Sponsor,  or may act as  depositary  for,  trustee or agent  for,  or act on any
committee or body of holders of,  securities or other obligations of the Sponsor
or its Affiliates.

     SECTION 11.1. FISCAL YEAR.

     The  fiscal  year  ("FISCAL  YEAR") of the  Trust  shall be the same as the
fiscal year of the Company.

     SECTION 11.2. CERTAIN ACCOUNTING MATTERS.

     (a) At all times during the  existence of the Trust,  the Regular  Trustees
shall keep, or cause to be kept, full books,  records and supporting  documents,
which  shall  reflect in detail,  each  transaction  of the Trust.  The books of
account shall be  maintained  on the accrual  method of accounting in compliance
with generally accepted accounting  principles,  consistently applied. The Trust
shall use the accrual  method of accounting for the United States federal income


                                       50
<PAGE>

tax  purposes.  The books of  account  and the  records  of the  Trust  shall be
examined by and reported  upon as of the end of each Fiscal Year of the Trust by
a firm of  independent  certified  public  accountants  selected  by the Regular
Trustees.

     (b) The Sponsor  shall cause to be prepared  and  delivered  to each of the
Holders of  Securities,  within 90 days after the end of each Fiscal Year of the
Sponsor,  annual financial statements of the Sponsor,  including a balance sheet
of the Sponsor as of the end of such Fiscal Year, and the related  statements of
income or loss.

     (c) The Regular  Trustees  shall cause to be duly prepared and delivered to
each of the Holders of  Securities,  any annual United States federal income tax
information  statement,  required by the Code,  containing such information with
regard to the Securities  held by each Holder as is required by the Code and the
Treasury  Regulations.  Notwithstanding  any right under the Code to deliver any
such statement at a later date,  the Regular  Trustees shall endeavor to deliver
all such  statements  within 30 days  after the end of each  Fiscal  Year of the
Trust.

     (d) The Regular Trustees shall cause to be duly prepared and filed with the
appropriate taxing authority, an annual United States federal income tax return,
on a Form 1041 or such other form required by United States  federal  income tax
law, and any other annual income tax returns required to be filed by the Regular
Trustees on behalf of the Trust with any state or local taxing authority.

     SECTION 11.3. BANKING.

     The Trust shall  maintain one or more bank accounts in the name and for the
sole  benefit of the Trust;  provided,  however,  that all  payments of funds in
respect  of the  Debentures  held by the  Institutional  Trustee  shall  be made
directly to the  Institutional  Trustee  Account and no other funds of the Trust
shall be deposited in the  Institutional  Trustee Account.  The sole signatories
for such  accounts  shall  be  designated  by the  Regular  Trustees;  provided,
however,  that the Institutional Trustee shall designate the signatories for the
Institutional Trustee Account.

     SECTION 11.4. WITHHOLDING.

     The  Trust and the  Regular  Trustees  shall  comply  with all  withholding
requirements  under United States federal,  state and local law. The Trust shall
request,  and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder,  and any  representations  and forms as shall reasonably be requested by
the Trust to assist it in  determining  the extent of,  and in  fulfilling,  its
withholding  obligations.  The Regular  Trustees  shall file required forms with
applicable  jurisdictions  and, unless an exemption from withholding is properly
established by a Holder, shall remit amounts withheld with respect to the Holder
to  applicable  jurisdictions.  To the  extent  that the  Trust is  required  to


                                       51
<PAGE>

withhold and pay over any amounts to any authority with respect to distributions
or  allocations  to any  Holder,  the  amount  withheld  shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of any
claimed  over-withholding,  Holders  shall be limited to an action  against  the
applicable jurisdiction.  If the amount required to be withheld was not withheld
from actual Distributions made, the Trust may reduce subsequent Distributions by
the  amount of such  withholding.  Furthermore,  if  withholding  is  imposed on
payments of  interest  on the  Debentures,  to the extent  such  withholding  is
attributable  to  ownership  by  a  specific  Holder  of  Convertible  Preferred
Securities,  the amount withheld shall be deemed a distribution in the amount of
the withholding to such specific Holder.


                                   ARTICLE XII

     (a) Meetings of the Holders of any class of Securities may be called at any
time by the Regular  Trustees (or as provided in the terms of the Securities) to


                                       54
<PAGE>

consider and act on any matter on which Holders of such class of Securities  are
entitled to act under the terms of this Declaration, the terms of the Securities
or the rules of any stock exchange on which the Convertible Preferred Securities
are listed or admitted for trading. The Regular Trustees shall call a meeting of
the Holders of such class if directed to do so by the Holders of at least 25% in
liquidation amount of such class of Securities. Such direction shall be given by
delivering to the Regular  Trustees one or more calls in a writing  stating that
the signing  Holders of  Securities  wish to call a meeting and  indicating  the
general or specific  purpose for which the meeting is to be called.  Any Holders
of  Securities   calling  a  meeting  shall  specify  in  writing  the  Security
Certificates  held by the Holders of Securities  exercising  the right to call a
meeting and only those  Securities  specified  shall be counted for  purposes of
determining  whether the required percentage set forth in the second sentence of
this paragraph has been met.

     (b) Except to the extent otherwise provided in the terms of the Securities,
the following provisions shall apply to meetings of Holders of Securities:

          (i) notice of any such  meeting  shall be given to all the  Holders of
     Securities having a right to vote thereat at least 7 days and not more than
     60 days before the date of such meeting. The presence of any Holder or such
     Holder's  proxy at a meeting  shall  constitute  a waiver of notice of such
     meeting  except when such Holder or proxy attends a meeting for the express
     purpose of objecting to the transaction of any activity on the grounds that
     the  meeting has not been  lawfully  called or  convened.  Whenever a vote,
     consent or approval of the Holders of  Securities  is permitted or required
     under  this  Declaration  or the rules of any stock  exchange  on which the
     Convertible  Preferred Securities are listed or admitted for trading,  such
     vote,  consent  or  approval  may be given at a meeting  of the  Holders of
     Securities.  Any action  that may be taken at a meeting  of the  Holders of
     Securities  may be taken without a meeting if a consent in writing  setting
     forth the action so taken is signed by the Holders of Securities owning not
     less than the minimum amount of Securities in liquidation amount that would
     be  necessary  to  authorize  or take such action at a meeting at which all
     Holders of  Securities  having a right to vote  thereon  were  present  and
     voting.  Prompt  notice of the taking of action  without a meeting shall be
     given to the Holders of Securities  entitled to vote who have not consented
     in  writing.  The Regular  Trustees  may  specify  that any written  ballot
     submitted  to the  Security  Holder  for the  purpose  of taking any action
     without a meeting shall be returned to the Trust within the time  specified
     by the Regular Trustees;

          (ii) each Holder of a Security may  authorize any Person to act for it
     by proxy on all  matters in which a Holder of  Securities  is  entitled  to
     participate,  including  waiving  notice  of  any  meeting,  or  voting  or
     participating at a meeting. No proxy shall be valid after the expiration of
     11 months from the date  thereof  unless  otherwise  provided in the proxy.
     Every proxy shall be revocable at the pleasure of the Holder of  Securities
     executing it. Except as otherwise  provided herein, all matters relating to
     the giving,  voting or validity of proxies shall be governed by the General


                                       55
<PAGE>

     Corporation Law of the State of Delaware relating to proxies,  and judicial
     interpretations thereunder, as if the Trust were a Delaware corporation and
     the Holders of the Securities were stockholders of a Delaware corporation;

          (iii) each meeting of the Holders of the Securities shall be conducted
     by the Regular  Trustees or by such other Person that the Regular  Trustees
     may designate; and

          (iv) unless the Business Trust Act, this Declaration, the terms of the
     Securities,  the  Trust  Indenture  Act or the  listing  rules of any stock
     exchange on which the Convertible  Preferred  Securities are then listed or
     trading,   otherwise  provides,   the  Regular  Trustees,   in  their  sole
     discretion,  shall establish all other  provisions  relating to meetings of
     Holders of Securities,  including  notice of the time,  place or purpose of
     any  meeting  at which  any  matter  is to be voted  on by any  Holders  of
     Securities, waiver of any such notice, action by consent without a meeting,
     the establishment of a record date, quorum  requirements,  voting in person
     or by proxy or any other  matter with  respect to the  exercise of any such
     right to vote.

                                     ANNEX I

                                    TERMS OF
                     7 3/4% CONVERTIBLE PREFERRED SECURITIES
                      7 3/4% CONVERTIBLE COMMON SECURITIES

     Pursuant to Section 7.1 of the Amended and Restated  Declaration  of Trust,
dated as of April 12, 2000 (as amended  from time to time,  the  "Declaration"),
the designation, rights, privileges,  restrictions,  preferences and other terms
and provisions of the Convertible Preferred Securities and the Common Securities
are set out below (each  capitalized  term used but not  defined  herein has the
meaning set forth in the Declaration or, if not defined in such Declaration,  as
defined in the Offering Memorandum referred to below):

     1. DESIGNATION AND NUMBER.

     (a)  CONVERTIBLE  PREFERRED  SECURITIES.  3,000,000  Convertible  Preferred
Securities  of the Trust  (3,600,000  Convertible  Preferred  Securities  if the
Initial  Purchasers'  over-allotment  option  is  exercised  in  full)  with  an
aggregate  liquidation  amount  with  respect  to the assets of the Trust of One
Hundred Fifty Million Dollars ($150,000,000) (One Hundred Eighty Million Dollars
($180,000,000) if the Initial Purchasers'  over-allotment option is exercised in
full),  and a  liquidation  amount  with  respect  to  the  assets  of  $50  per
convertible  preferred  security,  are hereby  designated  for the  purposes  of
identification  only  as  "7%  Trust  Convertible   Preferred  Securities"  (the
"CONVERTIBLE   PREFERRED   SECURITIES").   The  Convertible  Preferred  Security
Certificates   evidencing  the  Convertible   Preferred   Securities   shall  be
substantially in the form of Exhibit A-1 to the Declaration,  with such letters,
numbers,  notations,  other  means of  identification  or  designation  or other
changes or  additions  thereto or  deletions  therefrom  as may be  required  by
ordinary usage, custom or practice and such legends or endorsements  required by
law, state  exchange rule and  agreements to which the Trust is subject,  if any
(provided that any such notation,  legend or endorsement is in a form acceptable
to the Trust).

     (b) COMMON  SECURITIES.  92,783.5 Common Securities of the Trust (111,340.2
Common Securities if the Initial Purchasers'  over-allotment option is exercised
in full) with an aggregate  liquidation amount with respect to the assets of the
Trust of Four  Million  Six Hundred  Thirty-Nine  Thousand  Two Hundred  Dollars
($4,639,175)   (Five   Million  Five  Hundred   Sixty-Seven   Thousand   Dollars
($5,567,010) if the Initial  Purchasers'  over-allotment  option is exercised in
full),  and a liquidation  amount with respect to the assets of the Trust of $50
per common security,  are hereby  designated for the purposes of  identification
only as "7  3/4%  Common  Securities"  (the  "COMMON  SECURITIES").  The  Common
Securities Certificates evidencing the Common Securities shall be in the form of
Exhibit A-2 to the Declaration,  with such letters,  numbers,  notations,  other
means of  identification or designation or other changes or additions thereto or
deletions


                                      I-1
<PAGE>

therefrom  as may be  required by ordinary  usage,  custom or practice  and such
legends or  endorsements  required by law, state exchange rule and agreements to
which the Trust is subject,  if any (provided that any such notation,  legend or
endorsement is in a form acceptable to the Trust).

     2. DISTRIBUTIONS.

     (a)  Distributions  payable  on each  Security  will be fixed at a rate per
annum of 7 3/4% (the "COUPON  RATE")  of the stated  liquidation  amount  of $50
per Security,  such rate being the rate of interest payable on the Debentures to
be held by the Institutional Trustee. Distributions in arrears for more than one
quarter will bear interest thereon  compounded  quarterly at the Coupon Rate (to
the extent permitted by applicable law). The term "Distributions" as used herein
includes such interest  payable  unless  otherwise  stated.  A  Distribution  is
payable only to the extent that  payments are made in respect of the  Debentures
held by the Institutional  Trustee and to the extent the  Institutional  Trustee
has funds available therefor. The amount of Distributions payable for any period
will be computed for any full  quarterly  Distribution  period on the basis of a
360-day year of twelve  30-day  months,  and for any period  shorter than a full
quarterly   Distribution   period   for  which   Distributions   are   computed,
Distributions will be computed on the basis of the actual number of days elapsed
per 30-day month.

     (b)  Distributions  on the Securities will be cumulative,  will accrue from
April 12, 2000 and will be payable  quarterly  in arrears,  on January 15, April
15, July 15 and October 15 of each year,  commencing on July 15, 2000, except as
otherwise  described  below.  So long as the  Debenture  Issuer  shall not be in
default in the payment of interest on the Debentures,  the Debenture  Issuer has
the right under the Indenture to defer payments of interest on the Debentures by
extending the interest  payment period from time to time on the Debentures for a
period not  exceeding 20  consecutive  quarters  (each an  "EXTENSION  PERIOD"),
during  which  Extension  Period no  interest  shall be due and  payable  on the
Debentures,  provided  that no  Extension  Period  shall last beyond the date of
maturity or any  redemption  date of the  Debentures.  As a consequence  of such
deferral,  Distributions will also be deferred. Despite such deferral, quarterly
Distributions  will  continue  to accrue  with  interest  thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded  quarterly during any
such Extension  Period.  Prior to the termination of any such Extension  Period,
the Debenture  Issuer may further  extend such Extension  Period;  provided that
such  Extension  Period  together with all such previous and further  extensions
thereof may not exceed 20 consecutive  quarters or extend beyond the maturity or
any redemption date of the Debentures. Payments of accrued Distributions and, to
the extent  permitted by  applicable  law,  accrued  interest  thereon  shall be
payable on the Distribution  payment date on which the relevant Extension Period
terminates  and shall be  payable  to  Holders  as they  appear on the books and
records of the Trust at the close of business on the record date next  preceding
such Distribution payment date. Upon the termination of any Extension Period and


                                      I-2
<PAGE>

the payment of all amounts  then due,  the  Debenture  Issuer may commence a new
Extension Period,  subject to the above requirements.  Each Extension Period, if
any,  will end on an interest  payment date for the  Debentures;  such date will
also be a Distribution  payment date for the  Securities.  In the event that the
Debenture Issuer  exercises its right to defer payment of interest,  then during
such  Extension  Period  the  Debenture  Issuer  shall  not (a)  declare  or pay
dividends  on,  make  distributions  with  respect  to, or redeem,  purchase  or
acquire,  or make a  liquidation  payment  with  respect  to, any of its capital
stock, or (b) make any payment of interest,  principal or premium, if any, on or
repay,  repurchase or redeem any debt securities  issued by the Debenture Issuer
that rank pari passu with or junior in  interest to the  Debentures  or make any
guarantee  payments with respect to any guarantee by the Debenture Issuer of the
debt  securities of any  subsidiary of the  Debenture  Issuer if such  guarantee
ranks pari passu with or junior in interest to the Debentures (other than (i) as
a result of a  reclassification  of the capital stock of the Debenture Issuer or
the exchange or  conversion  of one class or series of the capital  stock of the
Debenture  Issuer  for  another  class or  series  of the  capital  stock of the
Debenture  Issuer,  (ii) the purchase of  fractional  interests in shares of the
capital stock of the  Debenture  Issuer  pursuant to the  conversion or exchange
provisions  of such  capital  stock  or the  security  being  converted  into or
exchanged for such capital stock,  (iii)  dividends or  distributions  in Common
Stock of the Debenture Issuer,  (iv) any declaration of a dividend in connection
with the implementation of a stockholders' rights plan, or the issuance of stock
under any such plan in the future,  or the  redemption or repurchase of any such
rights  pursuant  thereto,  (v) payments under the Securities  Guarantees,  (vi)
purchases of Common  Stock of the  Debenture  Issuer  related to the issuance of
Common  Stock of the  Debenture  Issuer  or rights  under  any of the  Debenture
Issuer's  benefit  plans for its  directors,  officers  or  employees  and (vii)
obligations under any dividend reinvestment and stock purchase plans).

     (c)  Distributions on the Securities will be payable to the Holders thereof
as they  appear on the books and  records  of the Trust on the  relevant  record
dates,  which shall be fifteen days prior to the relevant  payment dates,  which
payment  dates  correspond  to the  record  and  interest  payment  dates on the
Debentures.  The relevant  record dates for the Common  Securities  shall be the
same record dates as for the  Convertible  Preferred  Securities.  Distributions
payable  on any  Securities  that are not  punctually  paid on any  Distribution
payment  date,  as a result  of the  Debenture  Issuer  having  failed to make a
payment  under the  Debentures,  will cease to be payable to the Person in whose
name such  Securities  are  registered  on the relevant  record  date,  and such
defaulted  Distribution will instead be payable to the Person in whose name such
Securities  are  registered on the special  record date or other  specified date
determined in accordance with the Indenture.  If any date on which Distributions
are  payable  on the  Securities  is not a  Business  Day,  then  payment of the
Distributions  payable on such date will be made on the next succeeding day that
is a Business Day (and  without any interest or other  payment in respect of any
such delay) except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately  preceding  Business Day, in
each case with the same force and effect as if made on such date.

     (d) In the event of an  election  by the Holder to convert  its  Securities
through  the  Conversion  Agent into Common  Stock  pursuant to the terms of the
Securities  as set  forth  in  this  Annex  I to the  Declaration,  no  payment,
allowance or  adjustment  shall be made with respect to  accumulated  and unpaid
Distributions on such Securities, or be required to be made; provided,  however,


                                      I-3
<PAGE>

that Holders of  Securities  at the close of business on any record date for the
payment of Distributions  will be entitled to receive the Distributions  payable
on  such  Securities  on the  corresponding  payment  date  notwithstanding  the
conversion  of such  Securities  into Common Stock  following  such record date;
provided, further that if the date of any redemption of related Debentures falls
between such record date and such corresponding payment date, the amount of such
Distribution shall include accumulated and unpaid  Distributions  accrued to but
excluding  such  date  of  redemption  and  such  payment  shall  be made to the
converting holder.

     (e) In the event that there is any money or other  property  held by or for
the  Trust  that  is  not  accounted  for  hereunder,  such  property  shall  be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

     3. LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

     The  Sponsor  will  have the  right at any  time to cause  the  Trust to be
dissolved with the result that, after satisfaction of creditors of the Trust, as
provided by applicable  law,  Debentures  having an aggregate  principal  amount
equal to the aggregate stated  liquidation  amount of the Convertible  Preferred
Securities and the Common  Securities will be distributed on a pro rata basis to
the Holders of the Convertible Preferred Securities and the Common Securities in
liquidation  of such Holders'  interests in the Trust,  within 90 days following
notice given to the Holders of the Convertible Preferred Securities,  subject to
the Regular Trustees' receipt of an opinion of nationally recognized independent
counsel  experienced  in such  matters to the effect that the  Holders  will not
recognize any income, gain or loss for United States federal income tax purposes
as a result of the dissolution of the Trust and such  distribution to Holders of
Convertible Preferred Securities.

     In the event of any  voluntary  or  involuntary  liquidation,  dissolution,
winding-up or  termination of the Trust (each a  "LIQUIDATION"),  the Holders of
the Securities on the date of the Liquidation will be entitled to receive out of
the assets of the Trust  available  for  distribution  to Holders of  Securities
after  satisfaction of liabilities of creditors an amount equal to the aggregate
of the stated  liquidation  amount of $50 per  Security  plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "LIQUIDATION
DISTRIBUTION"),  unless, in connection with such  Liquidation,  Debentures in an
aggregate  stated  principal  amount equal to the aggregate  stated  liquidation
amount of such  Securities,  with an interest  rate equal to the Coupon Rate of,
and bearing  accrued and unpaid  interest in an amount  equal to the accrued and
unpaid  Distributions on, such Securities,  shall have been distributed on a Pro
Rata basis to the Holders of the Securities in exchange for such Securities.

     If, upon any such  Liquidation,  the Liquidation  Distribution  can be paid
only in part because the Trust has insufficient  assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Securities shall be paid on a Pro Rata basis.



                                      I-4

     4. REDEMPTION AND DISTRIBUTION.

     (a) The Debentures  will mature on April 15, 2015, and may be redeemed,  in
whole or in part,  at any time on or after  April  18,  2003,  or at any time in
certain  circumstances  upon the  occurrence of a Tax Event (as defined  below).
Upon the repayment of the  Debentures in whole or in part,  whether at maturity,
upon redemption  (either at the option of the Debenture  Issuer or pursuant to a
Tax Event as described below) or otherwise,  the proceeds from such repayment or
payment shall be simultaneously applied to redeem Securities having an aggregate
liquidation amount equal to the aggregate  principal amount of the Debentures so
repaid or redeemed at a redemption  price per Security  equal to the  redemption
price of the Debentures,  together with accrued and unpaid Distributions thereon
to, but excluding, the date of the redemption,  payable in cash (the "REDEMPTION
Price"). Holders will be given not less than 30 nor more than 60 days' notice of
such redemption.

     (b) If fewer than all the outstanding Securities are to be so redeemed, the
Common Securities and the Convertible  Preferred Securities will be redeemed Pro
Rata  and  the  Convertible  Preferred  Securities  to be  redeemed  will  be as
described in Section 4(f) below.

     (c) If, at any time, a Tax Event or an Investment  Company Event (each,  as
defined  below, a "SPECIAL  EVENT") shall occur and be  continuing,  the Regular
Trustees may with the consent of the Debenture Issuer, except in certain limited
circumstances  in  relation  to a Tax  Event  described  in this  Section  4(c),
dissolve the Trust and, after  satisfaction of creditors,  cause Debentures held
by the Institutional Trustee,  having an aggregate principal amount equal to the
aggregate stated  liquidation  amount of, with an interest rate identical to the
Coupon  Rate of, and  accrued  and unpaid  interest  equal to accrued and unpaid
Distributions on, and having the same record date for payment as the Securities,
to be  distributed  to the  Holders of the  Securities  in  liquidation  of such
Holders'  interests in the Trust on a Pro Rata basis,  within 90 days  following
the occurrence of such Special Event (the "90 DAY PERIOD");  provided,  however,
that such dissolution and  distribution  shall be conditioned on (i) the Regular
Trustees' receipt of an opinion of nationally recognized independent tax counsel
experienced in such matters (a "NO RECOGNITION OPINION"), which opinion may rely
on published revenue rulings of the Internal Revenue Service, to the effect that
the Holders of the  Securities  will not  recognize  any gain or loss for United
States federal  income tax purposes as a result of the  dissolution of the Trust
and the  distribution  of  Debentures,  (ii) in the  case  of a Tax  Event,  the
Debenture  Issuer or the Trust being unable to avoid,  within the 90 Day Period,
the Tax Event by taking some ministerial action, such as filing a form or making
an  election,  or pursuing  some other  similar  reasonable  measure that has no
adverse effect on the Trust, the Debenture Issuer, the Sponsor or the Holders of
the Securities  ("MINISTERIAL  ACTION"),  and (iii) the Debenture Issuer's prior
written consent to such dissolution and distribution.



                                      I-5
<PAGE>

     Furthermore,  if (i) after receipt of a Dissolution Tax Opinion (as defined
hereinafter)  by the Regular  Trustees,  the  Debenture  Issuer has  received an
opinion (a "REDEMPTION  TAX OPINION") of nationally  recognized  independent tax
counsel  experienced in such matters that, as a result of a Tax Event,  there is
more than an  insubstantial  risk that the  Debenture  Issuer would be precluded
from  deducting the interest on the  Debentures for United States federal income
tax  purposes  even after the  Debentures  were  distributed  to the  Holders of
Securities in liquidation  of such Holders'  interests in the Trust as described
in this Section 4(c), or (ii) the Regular  Trustees  shall have been informed by
such tax counsel that it cannot deliver a No  Recognition  Opinion to the Trust,
the Debenture  Issuer shall have the right,  upon not less than 30 nor more than
60 days' notice, to redeem the Debentures,  in whole or in part, at a redemption
price equal to 100% of the  principal  amount  thereof  plus  accrued and unpaid
interest  thereon  (including  Additional  Sums (as such term is  defined in the
Indenture),  if any, and, to the extent  permitted by applicable  law,  Compound
Interest (as such term is defined in the Indenture), if any), for cash within 90
days  following the  occurrence of such Tax Event.  Following  such  redemption,
Securities with an aggregate liquidation amount equal to the aggregate principal
amount of the  Debentures  so  redeemed  shall be  redeemed  by the Trust at the
Redemption Price on a Pro Rata basis;  provided,  however,  that, if at the time
there is  available  to the  Debenture  Issuer or the Trust the  opportunity  to
eliminate,  within such 90 day period,  the Tax Event by taking some Ministerial
Action, the Trust or the Debenture Issuer will pursue such Ministerial Action in
lieu of redemption.

     "TAX EVENT" means that the Regular  Trustees shall have received an opinion
of nationally recognized  independent tax counsel experienced in such matters (a
"DISSOLUTION  TAX  OPINION") to the effect that on or after April 12, 2000, as a
result of (a) any  amendment  to,  clarification  of, or change  (including  any
announced prospective change) in the laws (or any regulations thereunder) of the
United  States or any  political  subdivision  or taxing  authority  thereof  or
therein affecting taxation, (b) any judicial decision,  official  administrative
pronouncement,  ruling, regulatory procedure, notice or announcement,  including
any notice or announcement of intent to adopt such procedures or regulations (an
"ADMINISTRATIVE ACTION") or (c) any amendment to, clarification of, or change in
the official  position or the  interpretation of such  Administrative  Action or
judicial decision that differs from the theretofore generally accepted position,
in  each  case,  by any  legislative  body,  court,  governmental  authority  or
regulatory   body,   irrespective   of  the  manner  in  which  such  amendment,
clarification,  change or Administrative  Action is made known, which amendment,
clarification,   change  or   Administrative   Action  is   effective   or  such
pronouncement  or decision is  announced,  in each case,  on or after,  April 6,
2000,  there  is the  creation  by  such  amendment,  clarification,  change  or
Administrative  Action of more than an insubstantial risk that (i) the Trust is,
or will be within 90 days of the date thereof,  subject to United States federal
income tax with respect to income  accrued or received on the  Debentures,  (ii)
the Trust is, or will be  within 90 days of the date  thereof,  subject  to more
than a de minimis  amount of taxes  (other than  withholding  taxes),  duties or
other  governmental  charges,  or (iii)  interest  paid in cash by the Debenture
Issuer  to the  Trust on the  Debentures  is not,  or within 90 days of the date
thereof will not be,  deductible,  in whole or in part, by the Debenture  Issuer
for United States federal income tax purposes.  Notwithstanding the foregoing, a
Tax Event shall not include any change in tax law that  requires  the  Debenture


                                      I-6
<PAGE>

Issuer for United States federal income tax purposes to defer taking a deduction
for any  original  issue  discount  ("OID")  that  accrues  with  respect to the
Debentures  until  the  interest  payment  related  to  such  OID is paid by the
Debenture Issuer in cash; provided,  that such change in tax law does not create
more than an insubstantial risk that the Debenture Issuer will be prevented from
taking a deduction  for OID accruing  with respect to the  Debentures  at a date
that is no  later  than the date the  interest  payment  related  to such OID is
actually paid by the Debenture Issuer in cash.

     "INVESTMENT  COMPANY  EVENT"  means that the  Regular  Trustees  shall have
received an opinion of nationally recognized  independent counsel experienced in
such matters to the effect that,  as a result of the  occurrence  of a change in
law or regulation or a written change in interpretation or application of law or
regulation by any legislative  body,  court,  governmental  agency or regulatory
authority on or after April 6, 2000 (a "CHANGE IN 1940 ACT LAW"),  there is more
than  an  insubstantial  risk  that  the  Trust  is or  will  be  considered  an
"investment  company"  that is required to be  registered  under the  Investment
Company Act of 1940, as amended (the "1940 ACT").

     After  the date  fixed by the  Regular  Trustees  for any  distribution  of
Debentures upon  dissolution of the Trust:  (i) the Securities will no longer be
deemed to be outstanding,  (ii) The Depository Trust Company (the  "DEPOSITORY")
or its nominee (or any successor Clearing Agency or its nominee),  as the record
Holder of the Convertible Preferred Securities held in global form, will receive
a registered  certificate or  certificates  representing  the Debentures held in
global  form to be  delivered  upon such  distribution,  and (iii)  certificates
representing  Securities  held  in  definitive  form,  except  for  certificates
representing  Convertible  Preferred  Securities  held by the  Depository or its
nominee (or any successor  Clearing  Agency or its  nominee),  will be deemed to
represent Debentures having an aggregate principal amount equal to the aggregate
stated liquidation amount of, with an interest rate identical to the Coupon Rate
of, and accrued and unpaid interest  (including Compound Interest (as defined in
the  Indenture))  equal to accrued and unpaid  Distributions  on such Securities
until such  certificates  are presented to the Debenture Issuer or its agent for
transfer or reissue.

     (d) The Trust may not  redeem  fewer  than all the  outstanding  Securities
unless all accrued and unpaid Distributions have been paid on all Securities for
all  quarterly  Distribution  periods  terminating  on or  prior  to the date of
redemption.

     (e)  (i)  Notice  of any  redemption  of,  or  notice  of  distribution  of
Debentures in exchange for, the Securities (a "REDEMPTION/DISTRIBUTION  NOTICE")
will be given by the Trust by mail to each Holder of  Securities  to be redeemed
or  exchanged  not fewer than 30 nor more than 60 days before the date fixed for
redemption or exchange  thereof which, in the case of a redemption,  will be the
date fixed for redemption of the Debentures.  For purposes of the calculation of
the date of  redemption  or  exchange  and the dates on which  notices are given
pursuant to this Section 4(e), a Redemption/Distribution  Notice shall be deemed
to be given on the day such notice is first mailed by first-class mail,  postage
prepaid,  or by such other  means  suitable to assure  delivery of such  written
notice, to Holders of Securities. Each  Redemption/Distribution  Notice shall be


                                      I-7
<PAGE>

addressed  to the  Holders of  Securities  at the  address  of each such  Holder
appearing   in  the  books  and   records  of  the  Trust.   No  defect  in  the
Redemption/Distribution  Notice or in the mailing of either thereof with respect
to any Holder of  Securities  shall  affect the  validity of the  redemption  or
exchange proceedings with respect to any other Holder of Securities.

     (ii) In  addition to the  Redemption/Distribution  Notice to be provided to
the Holders of  Securities  pursuant  to clause (i) of this  Section  4(e),  the
Debenture Issuer or the Trust shall give public notice of any such redemption by
the  issuance of a press  release  through  the  services of the Dow Jones Broad
Tape, Reuters News Service and Bloomberg News Service.

     (f) In the event that fewer than all the  outstanding  Securities are to be
redeemed,  the  Securities  to be redeemed  shall be redeemed Pro Rata from each
Holder of Convertible Preferred Securities, it being understood that, in respect
of Convertible Preferred Securities registered in the name of and held of record
by the  Depository  or its  nominee  (or any  successor  Clearing  Agency or its
nominee) or any nominee,  the  distribution  of the proceeds of such  redemption
will be made to each Clearing Agency Participant (or Person on whose behalf such
nominee holds such securities) in accordance with the procedures applied by such
agency or nominee.

     (g)  If   Securities   are  to  be   redeemed   and  the   Trust   gives  a
Redemption/Distribution Notice, which notice may only be issued for a redemption
if the Debentures  are redeemed as set out in Article X of the Indenture  (which
notice will be  irrevocable),  then (i) with  respect to  Convertible  Preferred
Securities  held in  book-entry  form by 12:00 noon,  New York City time, on the
redemption date,  provided that the Debenture Issuer has paid the  Institutional
Trustee a sufficient amount of cash in connection with the related redemption of
the Debentures,  the  Institutional  Trustee will deposit  irrevocably  with the
Depository or its nominee (or successor  Clearing  Agency or its nominee)  funds
sufficient  to  pay  the  applicable  Redemption  Price  with  respect  to  such
Convertible  Preferred  Securities  and  will  give the  Depository  irrevocable
instructions  and authority to pay the  Redemption  Price to the Holders of such
Convertible Preferred Securities, and (ii) with respect to Convertible Preferred
Securities  issued in definitive form and Common  Securities,  provided that the
Debenture Issuer has paid the Institutional  Trustee a sufficient amount of cash
in connection with the related  redemption of the Debentures,  the Institutional
Trustee will pay the relevant Redemption Price to the Holders of such Securities
by check mailed to the address of the relevant Holder appearing on the books and
records of the Trust on the redemption date. If a Redemption/Distribution Notice
shall have been given in  connection  with a redemption  and funds  deposited as
required,  then from and after the required date of such deposit,  distributions
will cease to accrue on the  Securities so called for  redemption and all rights
of Holders of such  Securities so called for redemption  will cease,  except the
right of the Holders of such  Securities to receive the  Redemption  Price,  but
without  interest on such Redemption  Price. If any date fixed for redemption of
Securities is not a Business Day, then payment of the  Redemption  Price payable
on such date will be made on the next  succeeding  Business Day (and without any


                                      I-8
<PAGE>

interest or other  payment in respect of any such delay)  except  that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
in respect of any  Securities  is  improperly  withheld  or refused and not paid
either by the Institutional  Trustee or by the Sponsor as guarantor  pursuant to
the  relevant  Securities  Guarantee,  Distributions  on  such  Securities  will
continue  to accrue  from the  original  redemption  date to the actual  date of
payment, in which case the actual payment date will be considered the date fixed
for redemption for purposes of calculating the Redemption Price.

     Neither the  Regular  Trustees  nor the Trust shall be required  (i) in the
event of any redemption in part, to issue,  register the transfer of or exchange
any  Securities  during a period  beginning  at the  opening of business 15 days
before any  selection for  redemption  of Securities  and ending at the close of
business  on the  earliest  date in which the  relevant  Redemption/Distribution
Notice is  deemed  to have been  given to all  holders  of  Securities  to be so
redeemed or (ii) to register the transfer of or exchange any Securities selected
for redemption,  in whole or in part,  except for the unredeemed  portion of any
Securities being redeemed in part.

     (h)  Redemption/Distribution  Notices shall be sent by the Regular Trustees
on behalf of the Trust to (i) in respect  of  Convertible  Preferred  Securities
held in global form,  the  Depository or its nominee (or any successor  Clearing
Agency or its nominee),  (ii) with respect to Convertible  Preferred  Securities
held in  definitive  form, to the Holders  thereof,  and (iii) in respect of the
Common Securities, to the Holders thereof.

     (i)  Subject  to the  foregoing  and  applicable  law  (including,  without
limitation,  United States federal  securities  laws), the Sponsor or any of its
subsidiaries  may at any  time  and  from  time  to  time  purchase  outstanding
Convertible Preferred Securities by tender, in the open market or otherwise.

     5. CONVERSION RIGHTS.

     The Holders of Securities shall have the right at any time, after April 12,
2000,  through  the  close of  business  on April 14,  2015 (or,  in the case of
Securities called for redemption, prior to the close of business on the Business
Day prior to the  redemption  date),  at their option,  to cause the  Conversion
Agent to convert Securities, on behalf of the converting Holders, into shares of
Common  Stock in the manner  described  herein on and  subject to the  following
terms and conditions:

          (a) The Securities will be convertible at the office of the Conversion
     Agent into fully paid and nonassessable  shares of Common Stock pursuant to
     the Holder's  direction to the Conversion Agent to exchange such Securities
     for a portion of the Debentures  theretofore held by the Trust on the basis
     of one Security per $50 principal  amount of  Debentures,  and  immediately
     convert such amount of Debentures into fully paid and nonassessable  shares
     of Common  Stock at an initial rate of 1.048 shares of Common Stock per $50


                                      I-9
<PAGE>

     principal  amount of Debentures  (which is equivalent to a conversion price
     of $47.71 per share of Common  Stock,  subject to certain  adjustments  set
     forth  in  Article  XII  of the  Indenture  (as  so  adjusted,  "CONVERSION
     PRICE")).

          (b) In order to convert Securities into Common Stock, the Holder shall
     submit to the  Conversion  Agent at its  office an  irrevocable  request to
     convert  Securities  on behalf of such Holder (the  "CONVERSION  REQUEST"),
     together,   if  the  Securities  are  in   certificated   form,  with  such
     certificates.  The  Conversion  Request  shall (i) set forth the  number of
     Securities to be converted and the name or names, if other than the Holder,
     in which the shares of Common  Stock  should be issued and (ii)  direct the
     Conversion  Agent (a) to  exchange  such  Securities  for a portion  of the
     Debentures  held by the Trust  (at the rate of  exchange  specified  in the
     preceding  paragraph)  and (b) to  immediately  convert such  Debentures on
     behalf of such Holder,  into Common Stock (at the conversion rate specified
     in the preceding paragraph). The Conversion Agent shall notify the Trust of
     the  Holder's  election  to  exchange  Securities  for  a  portion  of  the
     Debentures  held by the Trust and the Trust  shall,  upon  receipt  of such
     notice, deliver to the Conversion Agent the appropriate principal amount of
     Debentures  for exchange in accordance  with this Section.  The  Conversion
     Agent shall  thereupon  notify  Viatel of the Holder's  election to convert
     such Debentures  into shares of Common Stock.  Holders of Securities at the
     close of business on a Distribution record date will be entitled to receive
     the   Distribution   payable  on  such  securities  on  the   corresponding
     Distribution payment date notwithstanding the conversion of such Securities
     following  such record date but prior to such  distribution  payment  date;
     provided,  however,  that if the  date  of any  redemption  of the  related
     Debentures  falls  between  such record  date and the related  Distribution
     payment date, the amount of such Distribution shall include accumulated and
     unpaid Distributions accrued to but excluding such date of redemption,  and
     such payment shall be made to the  converting  Holder.  Holders who convert
     Securities   after  April  15,  2014  shall  be  paid  accrued  and  unpaid
     Distributions  payable on such  Securities  within 5  Business  Days of the
     conversion of such Securities.  Except as provided above, neither the Trust
     nor the Sponsor will make, or be required to make,  any payment,  allowance
     or adjustment  upon any conversion on account of any accumulated and unpaid
     Distributions  accrued on the Securities  (including any Additional Amounts
     accrued  thereon)  surrendered  for  conversion,   or  on  account  of  any
     accumulated and unpaid  dividends on the shares of Common Stock issued upon
     such  conversion,  except to the extent that such shares are held of record
     on the record date for any such  distributions.  Securities shall be deemed
     to have been  converted  immediately  prior to the close of business on the
     day on which a Notice of Conversion relating to such Securities is received
     by the Trust in accordance  with the foregoing  provision (the  "CONVERSION
     DATE").  The Person or Persons  entitled to receive  Common Stock  issuable
     upon conversion of the Debentures  shall be treated for all purposes as the
     record  holder or holders of such Common Stock at such time. As promptly as
     practicable on or after the Conversion Date, Viatel shall issue and deliver
     at the office of the Conversion Agent a certificate or certificates for the
     number of full  shares  of  Common  Stock  issuable  upon such  conversion,


                                      I-10
<PAGE>

     together  with the cash  payment,  if any,  in lieu of any  fraction of any
     share to the  Person or  Persons  entitled  to  receive  the  same,  unless
     otherwise  directed  by the  Holder  in the  notice of  conversion  and the
     Conversion  Agent shall distribute such certificate or certificates to such
     Person or Persons.

          (c) Each Holder of a Security by his acceptance  thereof  appoints The
     Bank of New York as  "Conversion  Agent" for the purpose of  effecting  the
     conversion of Securities in accordance with this Section.  In effecting the
     conversion and transactions described in this Section, the Conversion Agent
     shall be acting  as agent of the  Holders  of  Securities  directing  it to
     effect  such  conversion  transactions.  The  Conversion  Agent  is  hereby
     authorized (i) to exchange Securities from time to time for Debentures held
     by the  Trust in  connection  with the  conversion  of such  Securities  in
     accordance  with this  Section  and (ii) to convert all or a portion of the
     Debentures into Common Stock and thereupon to deliver such shares of Common
     Stock in accordance  with the  provisions of this Section and to deliver to
     the Trust a new  Debenture  or  Debentures  for any  resulting  unconverted
     principal amount.

          (d) No fractional shares of Common Stock will be issued as a result of
     conversion of Securities, but in lieu thereof such fractional interest will
     be paid in cash by Viatel,  in an amount based on the Closing  Price of the
     Common Stock on the date such Securities are surrendered for conversion, to
     the Conversion Agent, which in turn will make such payment to the Holder or
     Holders of Securities so converted.

          (e) Viatel shall at all times  reserve and keep  available  out of its
     authorized  and  unissued  Common  Stock,  solely  for  issuance  upon  the
     conversion  of the  Debentures,  free from any  preemptive or other similar
     rights, such number of shares of Common Stock as shall from time to time be
     issuable  upon  the  conversion  of all the  Debentures  then  outstanding.
     Notwithstanding  the  foregoing,  Viatel  shall be entitled to deliver upon
     conversion of Debentures, shares of Common Stock reacquired and held in the
     treasury of Viatel (in lieu of the  issuance  of  authorized  and  unissued
     shares of Common Stock),  so long as any such treasury  shares are free and
     clear of all liens, charges, security interests or encumbrances. Any shares
     of Common  Stock issued upon  conversion  of the  Debentures  shall be duly
     authorized,  validly  issued  and fully paid and  nonassessable.  The Trust
     shall deliver the shares of Common Stock  received  upon  conversion of the
     Debentures to the converting  Holder free and clear of all liens,  charges,
     security  interests and encumbrances,  except for United States withholding
     taxes.  Each of Viatel and the Trust  shall  prepare and shall use its best
     efforts to obtain and keep in force such governmental or regulatory permits
     or other  authorizations  as may be required by law,  and shall comply with
     all applicable  requirements as to registration or  qualification of Common
     Stock (and all  requirements  to list Common Stock issuable upon conversion
     of Debentures that are at the time  applicable),  in order to enable Viatel
     to  lawfully  issue  Common  Stock  to the  Trust  upon  conversion  of the


                                      I-11
<PAGE>

     Debentures  and the Trust to lawfully  deliver  Common Stock to each Holder
     upon conversion of the Securities.

          (f)  Viatel  will pay any and all taxes that may be payable in respect
     of the  issue or  delivery  of  shares of  Common  Stock on  conversion  of
     Debentures and the delivery of the shares of Common Stock by the Trust upon
     conversion of the Securities. Viatel shall not, however, be required to pay
     any tax which may be payable in respect  of any  transfer  involved  in the
     issue and  delivery of shares of Common  Stock in a name other than that in
     which the  Securities so converted  were  registered,  and no such issue or
     delivery  shall be made unless and until the person  requesting  such issue
     has paid to the Trust the amount of any such tax, or has established to the
     satisfaction of the Trust that such tax has been paid.

          (g) Nothing in the preceding Paragraph (f) shall limit the requirement
     of the Trust to withhold  taxes  pursuant to the terms of the Securities or
     as set  forth  in this  Annex I to the  Declaration  or to the  Declaration
     itself or otherwise require the  Institutional  Trustee or the Trust to pay
     any amounts on account of such withholdings.

          (h) The term  "Closing  Price" with respect to any security on any day
     means the last reported sale price, regular way on such day, or, if no sale
     takes place on such day, the average of the reported  closing bid and asked
     prices on such day,  regular  way,  in either  case as reported on the NYSE
     Composite  Tape,  or, if such security is not listed or admitted to trading
     on the NYSE, on the principal  national  securities  exchange on which such
     security  is listed or admitted  to  trading,  or, if such  security is not
     listed or admitted  to trading on a national  securities  exchange,  on the
     National Market System of the National  Association of Securities  Dealers,
     Inc.,  or, if such  security  is not quoted or  admitted to trading on such
     quotation system, on the principal  quotation system on which such security
     is listed or admitted  to trading or quoted,  or, if not listed or admitted
     to trading  or quoted on any  national  securities  exchange  or  quotation
     system, the average of the closing bid and asked prices of such security in
     the  over-the-counter  market on the day in  question  as  reported  by the
     National  Quotation Bureau  Incorporated,  or a similar generally  accepted
     reporting service,  or, if not so available in such manner, as furnished by
     any NYSE member firm  selected  from time to time by the board of Directors
     (or any  committee  duly  authorized  by the  Board  of  Directors)  of the
     Debenture  Issuer for that  purpose or, if not so available in such manner,
     as otherwise  determined  in good faith by the Board of  Directors  (or any
     committee  duly  authorized  by the Board of  Directors)  of the  Debenture
     Issuer.

     6. VOTING AND OTHER RIGHTS - CONVERTIBLE PREFERRED SECURITIES.

     (a) Except as  provided  under  Sections  6(b) and 8 of this Annex I to the
Declaration and as otherwise required by law and the Declaration, the Holders of
the Convertible Preferred Securities will not have voting rights.



                                      I-12
<PAGE>

     (b) Subject to the requirements set forth in this paragraph, the Holders of
a Majority in liquidation  amount of the Convertible  Preferred  Securities then
outstanding,  voting  separately as a class,  may direct the time,  method,  and
place of conducting any proceeding for any remedy available to the Institutional
Trustee,  or may direct the  exercise of any trust or power  conferred  upon the
Institutional  Trustee under the Declaration,  including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the remedies
available  under the Indenture  with respect to the  Debentures,  (ii) waive any
past  default and its  consequences  that is waivable  under  Section 5.9 of the
Indenture,  or (iii)  exercise any right to rescind or annul a declaration  that
the principal of all the Debentures shall be due and payable, provided, however,
that if an Event of Default  under the  Indenture has occurred and is continuing
then the holders of 25% of the aggregate  liquidation  amount of the Convertible
Preferred  Securities then outstanding may direct the  Institutional  Trustee to
declare the  principal of and  interest on the  Debentures  immediately  due and
payable; and provided,  further, that, where a consent under the Indenture would
require  the  consent or act of the  Holders of greater  than a majority  of the
Holders in principal amount of Debentures then outstanding (a "SUPER  MAJORITY")
affected thereby,  the Institutional  Trustee may only give such consent or take
such action at the written  direction of the Holders of at least the  proportion
in liquidation amount of the Convertible Preferred Securities which the relevant
Super Majority  represents of the aggregate  principal  amount of the Debentures
then  outstanding.  The  Institutional  Trustee  shall  not  revoke  any  action
previously  authorized  or approved by a vote of the Holders of the  Convertible
Preferred Securities.  Other than with respect to directing the time, method and
place of conducting  any remedy  available to the  Institutional  Trustee as set
forth above, the  Institutional  Trustee shall not take any action in accordance
with the directions of the Holders of the Convertible Preferred Securities under
this  paragraph  unless the  Institutional  Trustee  has  obtained an opinion of
nationally recognized independent tax counsel experienced in such matters to the
effect that for the purposes of United States  federal income tax the Trust will
not be classified  as other than a grantor trust as a result of such action.  If
the Institutional Trustee fails to enforce its rights under the Debentures,  any
Holder of Convertible  Preferred Securities may, to the fullest extent permitted
by law,  institute  a  legal  proceeding  against  any  Person  to  enforce  the
Institutional  Trustee's rights under the Debentures.  If a Declaration Event of
Default has occurred and is  continuing  and such event is  attributable  to the
failure of the Debenture  Issuer to pay interest or principal on the  Debentures
on the date such  interest or principal is otherwise  payable (or in the case of
redemption,  on the redemption  date),  then a Holder of  Convertible  Preferred
Securities  may directly  institute a proceeding  for  enforcement of payment to
such Holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate  liquidation  amount of the Convertible  Preferred
Securities  of such Holder (a "DIRECT  ACTION") on or after the  respective  due
date specified in the  Debentures.  In connection  with such Direct Action,  the
rights of the Holders of Common  Securities  will be subrogated to the rights of
such Holder of  Convertible  Preferred  Securities  to the extent of any payment
made by the Issuer to such Holder of  Convertible  Preferred  Securities in such
Direct  Action.  Except as provided in the preceding  sentences,  the Holders of
Convertible Preferred Securities will not be able to exercise directly any other
remedy available to the holders of the Debentures.



                                      I-13
<PAGE>

     Any approval or direction of Holders of  Convertible  Preferred  Securities
may  be  given  at a  separate  meeting  of  Holders  of  Convertible  Preferred
Securities  convened  for such  purpose,  at a meeting of all of the  Holders of
Securities  in the Trust or pursuant to written  consent.  The Regular  Trustees
will cause a notice of any  meeting at which  Holders of  Convertible  Preferred
Securities  are entitled to vote,  or of any matter upon which action by written
consent of such Holders is to be taken, to be mailed to each Holder of record of
Convertible  Preferred  Securities.  Each such notice  will  include a statement
setting  forth (i) the date of such  meeting or the date by which such action is
to be taken, (ii) a description of any resolution  proposed for adoption at such
meeting on which such  Holders are entitled to vote or of such matter upon which
written consent is sought and (iii)  instructions for the delivery of proxies or
consents.

     No vote or consent of the Holders of the Convertible  Preferred  Securities
will be  required  for the  Trust to redeem  and  cancel  Convertible  Preferred
Securities or to distribute  the Debentures in accordance  with the  Declaration
and the terms of the Securities.

     Notwithstanding  that  Holders  of  Convertible  Preferred  Securities  are
entitled to vote or consent under any of the circumstances  described above, any
of the  Convertible  Preferred  Securities  that are owned by the Sponsor or any
Affiliate of the Sponsor shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.

     7. VOTING RIGHTS - COMMON SECURITIES.

     (a) Except as provided under  Sections 7(b),  7(c) and 8 of this Annex I of
the  Declaration  and as  otherwise  required  by law and the  Declaration,  the
Holders of the Common Securities will not have voting rights.

     (b) The Holders of the Common  Securities are entitled,  in accordance with
Article V of the Declaration,  to vote to appoint, remove or replace any Trustee
or to increase or decrease the number of Trustees.

     (c) Subject to Section 2.6 of the  Declaration  and only after any Event of
Default with respect to the  Convertible  Preferred  Securities  has been cured,
waived, or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common  Securities,  voting  separately as a class,  may direct the time,
method,  and place of conducting any proceeding for any remedy  available to the
Institutional  Trustee,  or  exercising  any trust or power  conferred  upon the
Institutional  Trustee under the Declaration,  including (i) directing the time,
method,  place of  conducting  any  proceeding  for any remedy  available to the
Debenture  Trustee,  or exercising any trust or power conferred on the Debenture
Trustee  with  respect to the  Debentures,  (ii) waive any past  default and its
consequences  that is  waivable  under  Section 5.9 of the  Indenture,  or (iii)
exercise any right to rescind or annul a  declaration  that the principal of all
the  Debentures  shall be due and  payable,  provided  that,  where a consent or
action  under the  Indenture  would  require the consent or act of the  relevant
Super  Majority,  the  Institutional  Trustee may only give such consent or take


                                      I-14
<PAGE>

such action at the written  direction of the Holders of at least the  proportion
in liquidation amount of the Common Securities which the relevant Super Majority
represents of the aggregate principal amount of the Debentures outstanding.  The
Institutional  Trustee  shall not  revoke any action  previously  authorized  or
approved by a vote of the Holders of the Convertible Preferred Securities. Other
than with  respect to directing  the time,  method and place of  conducting  any
remedy available to the  Institutional  Trustee or the Debenture  Trustee as set
forth above, the  Institutional  Trustee shall not take any action in accordance
with the directions of the Holders of the Common Securities under this paragraph
unless  the  Institutional   Trustee  has  obtained  an  opinion  of  nationally
recognized  independent  tax counsel  experienced  in such matters to the effect
that for the purposes of United States  federal income tax the Trust will not be
classified  as other  than a grantor  trust on account  of such  action.  If the
Institutional  Trustee  fails to enforce its rights under the  Declaration,  any
Holder of  Common  Securities  may,  to the  fullest  extent  permitted  by law,
institute  a legal  proceeding  directly  against  any  Person  to  enforce  the
Institutional Trustee's rights under the Declaration,  without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

     Any approval or direction of Holders of Common Securities may be given at a
separate meeting of Holders of Common Securities convened for such purpose, at a
meeting of all of the Holders of  Securities in the Trust or pursuant to written
consent.  The  Regular  Trustees  will  cause a notice of any  meeting  at which
Holders of Common  Securities  are entitled to vote, or of any matter upon which
action by written  consent of such Holders is to be taken,  to be mailed to each
Holder of record of Common Securities. Each such notice will include a statement
setting  forth (i) the date of such  meeting or the date by which such action is
to be taken, (ii) a description of any resolution  proposed for adoption at such
meeting on which such  Holders are entitled to vote or of such matter upon which
written consent is sought and (iii)  instructions for the delivery of proxies or
consents.

     No vote or consent of the Holders of the Common Securities will be required
for the Trust to redeem  and  cancel  Common  Securities  or to  distribute  the
Debentures in accordance with the Declaration and the terms of the Securities.

     8. AMENDMENTS TO DECLARATION AND INDENTURE.

     (a) In addition to any requirements  under Section 12.1 of the Declaration,
if any  proposed  amendment  to the  Declaration  provides  for,  or the Regular
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers,  preferences or special rights of the Securities,  whether by way of
amendment to the Declaration or otherwise,  or (ii) the dissolution,  winding-up
or  termination  of the Trust,  other than as  described  in Section  8.1 of the
Declaration,  then the Holders of outstanding  Securities  voting  together as a
single class, will be entitled to vote on such amendment or proposal (but not on
any other  amendment or proposal)  and such  amendment or proposal  shall not be
effective  except  with the  approval  of the  Holders of at least a Majority in
liquidation  amount  of  the  Securities  then  outstanding   affected  thereby;


                                      I-15
<PAGE>

provided,  however, if any amendment or proposal referred to in clause (i) above
would  adversely  affect only the Convertible  Preferred  Securities or only the
Common Securities, then only the affected class will be entitled to vote on such
amendment  or proposal  and such  amendment  or proposal  shall not be effective
except with the  approval of a Majority in  liquidation  amount of such class of
Securities then outstanding.

     (b) In the event the consent of the Institutional  Trustee as the holder of
the  Debentures is required  under the Indenture  with respect to any amendment,
modification   or   termination  of  the  Indenture  or  the   Debentures,   the
Institutional  Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment,  modification or termination as directed by
a Majority in liquidation  amount of the  Securities  then  outstanding,  voting
together as a single class;  provided,  however,  that where a consent under the
Indenture  would  require  the  consent  of the  relevant  Super  Majority,  the
Institutional Trustee may only give such consent at the direction of the Holders
of at  least  the  proportion  in  liquidation  amount  of the  Securities  then
outstanding  which the  relevant  Super  Majority  represents  of the  aggregate
principal amount of the Debentures then outstanding; provided, further, that the
Institutional  Trustee  shall  not  take  any  action  in  accordance  with  the
directions of the Holders of the  Securities  under this Section 8(b) unless the
Institutional   Trustee  has  obtained  an  opinion  of  nationally   recognized
independent  tax counsel  experienced in such matters to the effect that for the
purposes of United States federal income tax the Trust will not be classified as
other than a grantor trust as a result of such action.

     9. PRO RATA.

     A  reference  in  these  terms of the  Securities  to any  distribution  or
treatment  as being "PRO RATA" shall mean pro rata to each Holder of  Securities
according to the  aggregate  liquidation  amount of the  Securities  held by the
relevant  Holder  in  relation  to  the  aggregate  liquidation  amount  of  all
Securities  outstanding  unless,  in relation to a payment,  an Event of Default
under the  Declaration  has occurred and is continuing,  in which case any funds
available to make such payment shall be paid first in cash to each Holder of the
Convertible Preferred Securities pro rata according to the aggregate liquidation
amount of Convertible  Preferred Securities held by the relevant Holder relative
to the aggregate  liquidation  amount of all  Convertible  Preferred  Securities
outstanding,  and only after  satisfaction of all amounts owed to the Holders of
the Convertible  Preferred  Securities,  to each Holder of Common Securities pro
rata according to the aggregate  liquidation amount of Common Securities held by
the relevant Holder relative to the aggregate  liquidation  amount of all Common
Securities outstanding.

     10. RANKING.

     The  Convertible  Preferred  Securities rank pari passu and payment thereon
shall  be made  Pro  Rata  with  the  Common  Securities  except  that,  where a


                                      I-16
<PAGE>

Declaration Event of Default occurs and is continuing,  the rights of Holders of
the Common  Securities to payment in respect of Distributions  and payments upon
liquidation,  redemption and otherwise are subordinated to the rights to payment
of the Holders of the Convertible Preferred Securities.

     11. ACCEPTANCE OF SECURITIES GUARANTEE AND INDENTURE.

     Each Holder of Convertible  Preferred Securities and Common Securities,  by
the acceptance  thereof,  agrees to the provisions of the Convertible  Preferred
Securities  Guarantee  and  the  Common  Securities   Guarantee,   respectively,
including  the  subordination  provisions  therein and to the  provisions of the
Indenture.

     12. NO PREEMPTIVE RIGHTS.

     The Holders of the Securities shall have no preemptive  rights to subscribe
for any additional securities.

     13. MISCELLANEOUS.

     These terms constitute a part of the Declaration.  The Sponsor will provide
a copy of the Declaration, the Convertible Preferred Securities Guarantee or the
Common  Securities  Guarantee  (as may be  appropriate),  and the Indenture to a
Holder without charge on written  request to the Sponsor at its principal  place
of business.

                          [FORM OF REVERSE OF SECURITY]

     Distributions  payable on each Convertible Preferred Security will be fixed
at a rate per annum of 7 3/4% (the  "COUPON  RATE")  of the  stated  liquidation
amount  of $50 per  Preferred  Security,  such rate  being the rate of  interest
payable on the Debentures to be held by the Institutional Trustee. Distributions
in arrears  for more than one  quarter  will bear  interest  thereon  compounded
quarterly at the Coupon Rate (to the extent  permitted by applicable  law).  The
term  "Distributions"  as used herein includes such cash  distributions  and any
such interest payable unless otherwise stated. A Distribution is payable only to
the extent  that  payments  are made in respect  of the  Debentures  held by the
Institutional  Trustee  and to the extent the  Institutional  Trustee  has funds
available therefor.  The amount of Distributions  payable for any period will be
computed for any full  quarterly  Distribution  period on the basis of a 360-day
year of twelve 30-day  months,  and for any period shorter than a full quarterly
Distribution period for which Distributions are computed,  Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

     Except as  otherwise  described  below,  Distributions  on the  Convertible
Preferred  Securities  will be  cumulative,  will accrue from April 12, 2000 and
will be payable  quarterly  in  arrears,  on January  15,  April 15, July 15 and
October 15 of each year,  commencing on July 15, 2000, which payment dates shall
correspond to the interest payment dates on the Debentures, to Holders of record
at the close of business on the regular record date for such Distribution  which
shall be the close of business 15 days prior to such  Distribution  payment date
unless otherwise provided in the Declaration. The Debenture Issuer has the right
under the  Indenture  to defer  payments of interest by  extending  the interest
payment period from time to time on the Debentures for a period not exceeding 20
consecutive  quarters (each an "EXTENSION  PERIOD");  provided that no Extension
Period shall last beyond the date of the maturity or any redemption  date of the
Debentures  and, as a consequence of such deferral,  Distributions  will also be
deferred. Despite such deferral, quarterly Distributions will continue to accrue
with interest  thereon (to the extent permitted by applicable law) at the Coupon
Rate  compounded  quarterly  during  any  such  Extension  Period.  Prior to the
termination  of any such  Extension  Period,  the  Debenture  Issuer may further
extend such Extension Period;  provided that such Extension Period together with
all such previous and further  extensions  thereof may not exceed 20 consecutive
quarters or extend beyond the maturity or any redemption date of the Debentures.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Debenture  Issuer may commence a new Extension  Period,  subject to the
above requirements.

     The Convertible Preferred Securities shall be redeemable as provided in the
Declaration.

     The Convertible  Preferred  Securities  shall be convertible into shares of
Common Stock, through (i) the exchange of Convertible Preferred Securities for a
portion of the Debentures and (ii) the immediate  conversion of such  Debentures
into Debenture Issuer Common Stock, in the manner and according to the terms set
forth in the Declaration.

     THE  SECURITY  EVIDENCED  HEREBY  HAS NOT BEEN  REGISTERED  UNDER  THE U.S.

     THE  TRANSFER  OF THE  SECURITY  EVIDENCED  HEREBY IS ALSO  SUBJECT  TO THE

     Viatel Financing Trust I, a statutory business trust created under the laws
of the State of Delaware (the "TRUST"),  hereby certifies that Viatel, Inc. (the
"HOLDER") is the registered owner of common securities of the Trust representing
undivided  beneficial interests in the assets of the Trust designated the 7 3/4%
Common  Securities  (liquidation  amount $50 per Common  Security)  (the "COMMON

terms of the Common Securities as set forth in Annex I to the Declaration.

Securities  Guarantee to the extent provided therein. The Sponsor will provide a
copy of the Declaration,  the Common Securities Guarantee and the Indenture to a

     Upon receipt of this  certificate,  the Holder is bound by the  Declaration

evidence of indirect beneficial ownership in the Debentures.

     IN WITNESS  WHEREOF,  the Trust has executed this certificate this 12th day

                                     Title: Regular Trustee
                                     Solely as trustee and not in his individual

                          [FORM OF REVERSE OF SECURITY]

     Distributions  payable on each Common  Security will be fixed at a rate per
annum, of 7 3/4% (the "COUPON RATE") of the stated liquidation amount of $50 per
Common Security,  such rate being the rate of interest payable on the Debentures
to be held by the Institutional Trustee.  Distributions in arrears for more than
one quarter will bear interest thereon  compounded  quarterly at the Coupon Rate
(to the extent  permitted by applicable law). The term  "Distributions"  as used
herein  includes such cash  distributions  and any such interest  payable unless
otherwise stated. A Distribution is payable only to the extent that payments are
made in respect of the Debentures held by the  Institutional  Trustee and to the
extent the  Institutional  Trustee has funds available  therefor.  The amount of
Distributions  payable for any period will be  computed  for any full  quarterly
Distribution  period on the basis of a 360-day year of twelve 30-day months, and
for any  period  shorter  than a full  quarterly  Distribution  period for which
Distributions are computed,  Distributions  will be computed on the basis of the
actual number of days elapsed 30-day per month.

     Except as otherwise described below, Distributions on the Common Securities
will be  cumulative,  will  accrue  from  April  12,  2000 and  will be  payable
quarterly  in arrears,  on January 15,  April 15, July 15 and October 15 of each
year,  commencing on July 15, 2000,  which payment dates shall correspond to the
interest  payment dates on the Debentures,  to Holders of record at the close of
business on the regular  record  date for such  Distribution  which shall be the
close  of  business  15 days  prior to such  Distribution  payment  date  unless
otherwise provided in the Declaration.  The Debenture Issuer has the right under
the Indenture to defer  payments of interest by extending  the interest  payment
period  from  time to time on the  Debentures  for a  period  not  exceeding  20
consecutive  quarters (each an "EXTENSION  PERIOD"),  provided that no Extension
Period  shall last  beyond the date of  maturity  of the  Debentures  and,  as a
consequence of such deferral,  Distributions will also be deferred. Despite such
deferral,  quarterly Distributions will continue to accrue with interest thereon
(to the  extent  permitted  by  applicable  law) at the Coupon  Rate  compounded
quarterly during any such Extension Period. Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension  Period together with all such previous and further
extensions  thereof may not exceed 20 consecutive  quarters or extend beyond the
date of maturity of the Debentures. Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

     The Common Securities shall be redeemable as provided in the Declaration.

     The Common  Securities  shall be  convertible  into shares of Common Stock,
through (i) the exchange of Common  Securities  for a portion of the  Debentures
and (ii) the  immediate  conversion of such  Debentures  into  Debenture  Issuer
Common  Stock,  in the  manner  and  according  to the  term  set  forth  in the
Declaration.

     INVESTOR,  THE HOLDER MUST, PRIOR TO SUCH TRANSFER,  FURNISH TO EACH OF THE
     TRUSTEE AND  VIATEL,  INC.  SUCH  CERTIFICATIONS,  LEGAL  OPINIONS OR OTHER
     INFORMATION  AS SUCH  PERSONS MAY  REASONABLY  REQUIRE TO CONFIRM THAT SUCH
     TRANSFER IS BEING MADE  PURSUANT TO AN EXEMPTION  FROM, OR IN A TRANSACTION
     NOT SUBJECT TO, THE  REGISTRATION  REQUIREMENTS  OF THE SECURITIES  ACT. AS
     USED HEREIN,  THE TERMS "OFFSHORE  TRANSACTION",  "UNITED STATES" AND "U.S.
     PERSON"  HAVE  THE  MEANINGS  GIVEN  TO THEM  BY  REGULATION  S  UNDER  THE
     SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO
     REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE  FOREGOING
     RESTRICTIONS.

          (b)   RESTRICTED GLOBAL NOTE LEGEND. The DTC Rule 144A Global, whether
or not an  Exchange  Note,  shall  also  bear the  following  legend on the face
thereof:

     DEPOSITORY  TRUST COMPANY TO VIATEL,  INC. OR ITS AGENT FOR REGISTRATION OF

     NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED  BY AN  AUTHORIZED
     REPRESENTATIVE  OF THE DEPOSITORY  TRUST COMPANY (AND ANY PAYMENT HEREON IS
     MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
     REPRESENTATIVE  OF THE DEPOSITORY TRUST COMPANY),  ANY TRANSFER,  PLEDGE OR
     OTHER USE HEREOF  FOR VALUE OR  OTHERWISE  BY OR TO ANY PERSON IS  WRONGFUL
     INASMUCH  AS THE  REGISTERED  OWNER  HEREOF,  CEDE & CO.,  HAS AN  INTEREST
     HEREIN.

     TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO  TRANSFERS IN WHOLE,  BUT
     NOT IN PART,  TO NOMINEES  OF CEDE & CO. OR TO A SUCCESSOR  THEREOF OR SUCH
     SUCCESSOR'S  NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE
     LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE  RESTRICTIONS SET FORTH IN
     SECTION 2.08 OF THE INDENTURE.

          (c)   REGULATION  S GLOBAL NOTE LEGEND.  Each European 144A Global and
Regulation  S Global,  whether  or not an  Exchange  Note,  shall  also bear the
following legend on the face thereof:

     THIS NOTE IS HELD BY THE DEPOSITORY (AS DEFINED IN THE INDENTURE  GOVERNING
     THIS NOTE) IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF,  AND
     IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY  CIRCUMSTANCES  EXCEPT THAT (1)
     THE TRUSTEE MAY MAKE SUCH NOTATIONS  HEREON AS MAY BE REQUIRED  PURSUANT TO
     SECTION  2.08 OF THE  INDENTURE,  (2) THIS GLOBAL NOTE MAY BE  EXCHANGED IN

     GLOBAL NOTE MAY BE  DELIVERED TO THE TRUSTEE FOR  CANCELLATION  PURSUANT TO
     SECTION 2.12 OF THE  INDENTURE AND (4) THIS GLOBAL NOTE MAY BE DELIVERED TO
     A SUCCESSOR DEPOSITORY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

          SECTION 2.03. EXECUTION, AUTHENTICATION AND DENOMINATIONS.  Subject to
Article Four, the aggregate principal amount of Notes (including Exchange Notes)
which may be authenticated and delivered under this Indenture is unlimited.  The
Notes shall be executed by two Officers of the  Company,  by facsimile or manual
signature, in the name and on behalf of the Company.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee or authenticating agent authenticates the Note, the Note
shall be valid nevertheless.

          A Note shall not be valid  until the Trustee or  authenticating  agent
manually  signs the  certificate  of  authentication  on the Note. The signature
shall be  conclusive  evidence that the Note has been  authenticated  under this
Indenture.

          At any  time  and  from  time  to time  after  the  execution  of this
Indenture,  the Trustee or an  authenticating  agent  shall,  upon  receipt of a
Company Order,  authenticate for original issue Notes in the aggregate principal
amount  specified in such Company  Order.  Such Company  Order shall specify the
amount of Notes to be authenticated,  the date on which the issue of Notes is to
be authenticated  and, in case of an issuance of Notes pursuant to Section 2.15,
shall certify that such issuance is in compliance with Article Four.

          The Trustee may appoint an authenticating agent reasonably  acceptable
to the  Company  to  authenticate  Notes.  Unless  limited  by the terms of such
appointment, an authenticating agent may authenticate Notes whenever the Trustee
may do so. Each  reference in this  Indenture to  authentication  by the Trustee
includes  authentication by such authenticating  agent. An authenticating  agent
has the same rights as an Agent to deal with the Company or an  Affiliate of the
Company.

          The Notes shall be issuable only in registered form without coupons in
principal amount of Euro 1,000 and any integral multiple of Euro 1,000 in excess
thereof.

          SECTION 2.04.  REGISTRAR AND PAYING AGENT.  The Company shall maintain
an office or agency in the City of New York  where  Notes may be  presented  for
registration of transfer or for exchange (the "REGISTRAR"),  an office or agency
in the City of New York and in the City of London,  United  Kingdom  and, in the
event  the Notes are  included  on the  Frankfurt  over-the-counter  market,  in
Frankfurt where Notes may be presented for payment (the "PAYING AGENT"),  and an
office or agency where  notices and demands to or upon the Company in respect of
the Notes and this  Indenture  may be served,  which shall be in the City of New
York and, in the event the Notes are included on the


                                       25
<PAGE>

Frankfurt  over-the-counter  market,  in Frankfurt.  The Company shall cause the
Registrar  to keep a register of the Notes and of their  transfer  and  exchange
(the "NOTE REGISTER"). The Company may have one or more co-Registrars and one or
more additional Paying Agents.

          The Company shall enter into an appropriate  agency agreement with any
Agent  not a  party  to  this  Indenture.  The  agreement  shall  implement  the
provisions of this Indenture  that relate to such Agent.  The Company shall give
prompt  written  notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent.  If the Company fails to maintain a
Registrar,  Paying Agent  and/or  agent for service of notices and demands,  the
Trustee  shall act as such  Registrar,  Paying Agent and/or agent for service of
notices and demands for so long as such failure shall continue.  The Company may
remove any Agent upon  written  notice to such Agent and the  Trustee;  PROVIDED
that no such  removal  shall become  effective  until (i) the  acceptance  of an
appointment  by a successor  Agent to such Agent as evidenced by an  appropriate
agency  agreement  entered  into by the  Company  and such  successor  Agent and
delivered  to the Trustee or (ii)  notification  to the Trustee that the Trustee
shall  serve  as such  Agent  until  the  appointment  of a  successor  Agent in
accordance with clause (i) of this proviso.  The Company,  any Subsidiary of the
Company,  or any Affiliate of any of them may act as Paying Agent,  Registrar or
co-Registrar, and/or agent for service of notice and demands; PROVIDED, HOWEVER,
that neither the Company, a Subsidiary of the Company nor an Affiliate of any of
them shall act as Paying Agent in connection with the defeasance of the Notes or
the discharge of this Indenture under Article Eight.

          The Company initially appoints the Trustee as Registrar, Paying Agent,
authenticating  agent and agent for service of notice and  demands.  The Company
initially  appoints the Euro Paying  Agent,  as Paying Agent with respect to the
European 144A Global and  Regulation S Global.  If, at any time,  the Trustee is
not the  Registrar,  the  Registrar  shall make  available  to the Trustee on or
before  each  Interest  Payment  Date and at such other times as the Trustee may
reasonably request, the names and addresses of the Holders as they appear in the
Note Register.

          SECTION  2.05.  PAYING  AGENT TO HOLD  MONEY IN TRUST.  Not later than
10:00 a.m. New York City time or 10:00 a.m. London time, as applicable,  on each
due date of the  principal,  premium,  if any,  or  interest  on any Notes,  the
Company  shall  deposit  with the  relevant  Paying  Agent money in  immediately
available funds sufficient to pay such principal,  premium,  if any, or interest
so becoming due. The Company shall require each Paying Agent, if any, other than
the Trustee to agree in writing  that such Paying  Agent shall hold in trust for
the benefit of the Holders or the Trustee all money held by the Paying Agent for
the payment of principal of, premium,  if any, or interest on the Notes (whether
such  money  has been paid to it by the  Company  or any  other  obligor  on the
Notes),  and that such  Paying  Agent shall  promptly  notify the Trustee of any
default by the  Company  (or any other  obligor on the Notes) in making any such
payment.  The  Company at any time may  require a Paying  Agent to pay all money
held by it to the Trustee and account for any funds  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 pay all money held by it
to the Trustee and to account for any funds disbursed. Upon doing so, the Paying


                                       26
<PAGE>

Agent shall have no further liability for the money so paid over to the Trustee.
If the Company or any  Subsidiary of the Company or any Affiliate of any of them
acts as Paying  Agent,  it will, on or before each due date of any principal of,
premium,  if any,  or interest  on the Notes,  segregate  and hold in a separate
trust fund for the benefit of the Holders a sum of money  sufficient to pay such
principal,  premium, if any, or interest so becoming due until such sum of money
shall be paid to such  Holders or  otherwise  disposed  of as  provided  in this
Indenture,  and will promptly notify the Trustee of its action or failure to act
as required by this Section 2.05.

          SECTION 2.06.  TRANSFER AND  EXCHANGE.  The Notes are issuable only in
registered  form.  A Holder may  transfer a Note by written  application  to the
Registrar  stating the name of the proposed  transferee and otherwise  complying
with the terms of this Indenture.  No such transfer shall be effected until, and
such transferee  shall succeed to the rights of a Holder only upon  registration
of the transfer by the Registrar in the Note Register. Prior to the registration
of any transfer by a Holder as provided herein,  the Company,  the Trustee,  and
any agent of the Company or the Trustee shall treat the Person in whose name the
Note is registered as the owner thereof for all purposes whether or not the Note
shall be overdue, and neither the Company, the Trustee, nor any such agent shall
be affected by notice to the contrary.  Furthermore, any Holder of a Global Note
shall,  by  acceptance of such Global Note,  agree that  transfers of beneficial
interests in such Global Note may be effected  only through a book-entry  system
maintained by the Depository (or its agent),  and that ownership of a beneficial
interest  in the Note shall be required to be  reflected  in a book entry.  When
Notes are  presented  to the  Registrar  or a  co-Registrar  with a  request  to
register the transfer or to exchange them for an equal principal amount of Notes
of other authorized  denominations  (including an exchange of Notes for Exchange
Notes),  the  Registrar  shall  register  the  transfer or make the  exchange as
requested if its  requirements for such  transactions are met;  PROVIDED that no
exchanges of Notes for Exchange Notes shall occur until a Registration Statement
shall have been declared effective by the Commission and that any Notes that are
exchanged  for  Exchange  Notes shall be  cancelled  by the  Trustee.  To permit
registrations   of  transfers  and  exchanges  in  accordance  with  the  terms,
conditions and  restrictions  hereof,  the Company shall execute and the Trustee
shall authenticate Notes at the Registrar's  request. No service charge shall be
made to any Holder for any registration of transfer or exchange or redemption of
the Notes,  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 similar governmental charge payable
upon transfers, exchanges or redemptions pursuant to Section 2.11, 4.11, 4.12 or
9.04).

          SECTION  2.07.  BOOK-ENTRY  PROVISIONS  FOR  GLOBAL  NOTES.  (a)  Each
Restricted  Global and Regulation S Global  initially shall (i) be registered in
the  name  of the  Depository  for  such  Global  Note  or the  nominee  of such
Depository,  (ii)  be  delivered  to the  Trustee  as  custodian  or the  Common
Depositary,  as  applicable,  for such  Depository and (iii) bear legends as set
forth in Section 2.02 hereof.

          Members of, or Participants in, the Depository ("AGENT MEMBERS") shall
have no rights  under this  Indenture  with  respect to any Global  Note held on


                                       27
<PAGE>

their behalf by the  Depository,  or the Trustee as its  custodian or the Common
Depositary,  as applicable,  or under any Global Note, 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  Note  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 its Agent  Members,  the operation of
customary  practices  governing the exercise of the rights of a beneficial owner
of any Note.

          (b) Transfers of a Global Note shall be limited to transfers of such
Global Note in whole,  but not in part,  to the  Depository,  its  successors or
their respective nominees,  or transfers between the Depository for the DTC Rule
144A Global and the  Depository  for the European  144A Global and  Regulation S
Global.  Transfers  of interests in one Global Note to parties who will hold the
interests  through the same Global Note will be effected in the  ordinary way in
accordance with the respective rules and operating  procedures of DTC, Euroclear
or  Clearstream,  as the case may be, and the provisions of Section 2.08 hereof.
In addition, U.S. Certificated Notes or Regulation S Certificated Notes shall be
transferred to all beneficial owners in exchange for their beneficial  interests
in a  Restricted  Global  or a  Regulation  S Global,  respectively,  if (i) the
Depository  with  respect to such Global  Notes  notifies the Company that it is
unwilling or unable to continue as Depository for the  Restricted  Global or the
Regulation  S Global,  as the case may be,  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
to the foregoing effect from the Depository or the Trustee.

          (c) Any  beneficial  interest  in one of the  Global  Notes  that is
transferred to a Person who takes delivery in the form of an interest in another
Global Note will, upon transfer, cease to be an interest in such Global Note and
become an interest in such other Global Note and,  accordingly,  will thereafter
be subject to all transfer restrictions, if any, and other procedures applicable
to beneficial interests in such other Global Note for as long as it remains such
an interest.

          (d) In  connection  with any transfer  pursuant to paragraph  (b) of
this  Section  2.07 of a portion of the  beneficial  interests  in a  Restricted
Global or  Regulation  S Global to  beneficial  owners who are  required to hold
Certificated  Notes,  the  Registrar  shall reflect on its books and records the
date and a  decrease  in the  principal  amount  of such  Restricted  Global  or
Regulation S Global in an amount equal to the principal amount of the beneficial
interest in such Restricted Global or Regulation S Global to be transferred, and
the Company shall execute,  and the Trustee shall authenticate and deliver,  one
or more U.S.  Certificated Notes or Regulation S Certificated Notes, as the case
may be, of like tenor and amount.

          (e) In connection with the transfer of all the beneficial  interests
in a Restricted  Global or Regulation S Global to beneficial  owners pursuant to
paragraph  (b) of this  Section  2.07,  the  Restricted  Global or  Regulation S
Global, as the case may be, shall be deemed to be surrendered to the Trustee for
cancellation,  and the Company shall execute, and the Trustee shall authenticate
and deliver,  to each beneficial  owner identified by the Depository in exchange
for its beneficial  interest in the Restricted Global or Regulation S Global, as


                                       28
<PAGE>

the case may be, an equal aggregate principal amount of U.S.  Certificated Notes
or  Regulation  S  Certificated  Notes,  as  the  case  may  be,  of  authorized
denominations.

          (f) Any U.S. Certificated Note delivered in exchange for an interest
in a Restricted  Global  pursuant to  paragraph  (b), (d) or (e) of this Section
2.07 shall,  except as otherwise  provided by  paragraphs  (f)(i)(x)  and (d) of
Section 2.08 hereof, bear the legend regarding transfer restrictions  applicable
to the U.S. Certificated Note set forth in Section 2.02.

          (g) Any  Regulation S Certificated Note delivered in exchange for an
interest in a Regulation S Global  pursuant to paragraph (b), (d) or (e) of this
Section 2.07 shall, except as otherwise provided by paragraphs (f)(i)(x) and (d)
of  Section  2.08  hereof,  bear  the  legend  regarding  transfer  restrictions
applicable  to the  Regulation  S  Certificated  Note set forth in Section  2.02
hereof.

          (h) The  registered  holder of a Global  Note may grant  proxies and
otherwise  authorize  any Person,  including  Agent Members and Persons that may
hold  interests  through  Agent  Members,  to take any action  which a Holder is
entitled to take under this Indenture or the Notes.

          (i) QIBs  that are  beneficial  owners of interests in a Global Note
may receive Certificated Notes (which shall bear the Private Placement Legend if
required by Section  2.02) in  accordance  with the  procedures  of the relevant
Depository.  In connection  with the execution,  authentication  and delivery of
such Certificated  Notes, the Registrar shall reflect on its books and records a
decrease  in the  principal  amount of the  relevant  Global  Note  equal to the
principal  amount of such  Certificated  Notes and the Company shall execute and
the Trustee shall authenticate and deliver one or more Certificated Notes having
an equal aggregate principal amount.

          (j) All Notes issued upon any transfer or exchange of Notes shall be
valid obligations of the Company,  evidencing the same debt, and entitled to the
same benefits under this Indenture,  as the Notes surrendered upon such transfer
or exchange.

          SECTION 2.08. SPECIAL TRANSFER PROVISIONS.  Unless and until a Note is
exchanged  for an Exchange  Note in  connection  with an effective  Registration
Statement  pursuant  to  the  Registration   Rights  Agreement,   the  following
provisions shall apply:

          (a) TRANSFERS  TO QIBS.  The following  provisions  shall apply with
respect to the registration of any proposed transfer of a U.S. Certificated Note
or an interest in a Restricted Global to a QIB (excluding Non-U.S. Persons):

          (i) If the Note to be  transferred  consists of (x) U.S.  Certificated
     Notes,  the Registrar shall register the transfer if such transfer is being
     made by a proposed  transferor  who has checked the box provided for on the
     form  of  Note  stating,  or has  otherwise  advised  the  Company  and the
     Registrar in writing,  that the sale has been made in  compliance  with the
     provisions  of Rule 144A to a transferee  who has signed the  certification


                                       29
<PAGE>

     provided  for on the form of Note  stating,  or has  otherwise  advised the
     Company and the Registrar in writing,  that it is  purchasing  the Note for
     its own  account or an account  with  respect  to which it  exercises  sole
     investment  discretion and that it and any such account is a QIB within the
     meaning  of Rule  144A,  and is aware  that the sale to it is being made in
     reliance  on  Rule  144A  and  acknowledges   that  it  has  received  such
     information regarding the Company as it has requested pursuant to Rule 144A
     or has determined not to request such information and that it is aware that
     the  transferor is relying upon its foregoing  representations  in order to
     claim  the  exemption  from  registration  provided  by Rule 144A or (y) an
     interest in a  Restricted  Global,  the  transfer of such  interest  may be
     effected  only through the  book-entry  system  maintained  by the relevant
     Depository.

          (ii) If the proposed transferee is an Agent Member, and the Note to be
     transferred  consists  of U.S.  Certificated  Notes,  upon  receipt  by the
     Registrar of the documents referred to in clause (i) and instructions given
     in  accordance   with  the  relevant   Depository's   and  the  Registrar's
     procedures,  the Registrar  shall reflect on its books and records the date
     and an increase in the principal amount of the relevant  Restricted  Global
     in an amount equal to the principal amount of the U.S.  Certificated  Notes
     to be transferred,  and the Trustee shall cancel the  Certificated  Note so
     transferred.

          (b) TRANSFERS  OF INTERESTS IN  REGULATION S GLOBAL OR  REGULATION S
CERTIFICATED  NOTES TO U.S. PERSONS.  The following  provisions shall apply with
respect to any transfer of  interests  in a Regulation S Global or  Regulation S
Certificated Notes to U.S. Persons:

          (i)  prior to the  removal  of the  Private  Placement  Legend  from a
     Regulation S Global or a Regulation S Certificated Note pursuant to Section
     2.02, the Registrar shall refuse to register such transfer; and

          (ii) after such removal,  the Registrar shall register the transfer of
     any such Note without requiring any additional certification.

          (c) TRANSFERS  TO  NON-U.S.  PERSONS  AT  ANY  TIME.  The  following
provisions  shall  apply with  respect to any  transfer  of a Note to a Non-U.S.
Person:

          (i) The Registrar shall register any proposed transfer to any Non-U.S.
     Person  if the Note to be  transferred  is a U.S.  Certificated  Note or an
     interest  in a  Restricted  Global  only  upon  receipt  of  a  certificate
     substantially in the form of Exhibit E from the proposed transferor.

          (ii) (a) If the  proposed  transferor  is an Agent  Member  holding  a
     beneficial  interest in a Restricted Global,  upon receipt by the Registrar
     of (x) the  documents  required by paragraph  (i) and (y)  instructions  in
     accordance with the relevant  Depository's and the Registrar's  procedures,
     the  Registrar  shall  reflect  on its  books  and  records  the date and a
     decrease in the  principal  amount of such  Restricted  Global in an amount
     equal to the principal amount of the beneficial  interest in the Restricted
     Global to be  transferred,  and (b) if the proposed  transferee is an Agent
     Member,  upon receipt by the Registrar of instructions  given in accordance


                                       30
<PAGE>

     with  the  relevant  Depository's  and  the  Registrar's  procedures,   the
     Registrar  shall  reflect on its books and records the date and an increase
     in the principal  amount of such  Regulation S Global in an amount equal to
     the  principal  amount  of the U.S.  Certificated  Notes or the  Restricted
     Global, as the case may be, to be transferred, and the Trustee shall cancel
     the Certificated Note, if any, so transferred or decrease the amount of the
     relevant Restricted Global.

          (d) PRIVATE  PLACEMENT  LEGEND.  Upon the  registration of transfer,
exchange or replacement of Notes not bearing the Private Placement  Legend,  the
Registrar  shall  deliver Notes that do not bear the Private  Placement  Legend.
Upon the registration of transfer,  exchange or replacement of Notes bearing the
Private Placement  Legend,  the Registrar shall deliver only Notes that bear the
Private  Placement  Legend unless either (i) the Private  Placement Legend is no
longer  required by Section 2.02 or (ii) there is delivered to the  Registrar 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.

          (e) GENERAL.  By its  acceptance  of any Note  bearing  the  Private
Placement  Legend,  each Holder of such a Note  acknowledges the restrictions on
transfer of such Note set forth in this  Indenture and in the Private  Placement
Legend and  agrees  that it will  transfer  such Note only as  provided  in this
Indenture.  The Registrar  shall not register a transfer of any Note unless such
transfer  complies with the  restrictions  on transfer of such Note set forth in
this  Indenture.  In connection  with any transfer of Notes to an  Institutional
Accredited  Investor,  each  Holder  agrees  by its  acceptance  of the Notes to
furnish the  Registrar or the Company  such  certifications,  legal  opinions or
other information as either of them may reasonably  require to confirm that such
transfer is being made  pursuant to an  exemption  from,  or a  transaction  not
subject to, the registration  requirements of the Securities Act;  PROVIDED that
the  Registrar   shall  not  be  required  to  determine  (but  may  rely  on  a
determination  made by the Company with respect to) the  sufficiency of any such
certifications, legal opinions or other information.

          The  Registrar   shall  retain,   in  accordance  with  its  customary
procedures,  copies of all  letters,  notices and other  written  communications
received  pursuant to Section 2.07 or this Section 2.08.  The Company shall have
the right to  inspect  and make  copies of all such  letters,  notices  or other
written  communications  at any  reasonable  time upon the giving of  reasonable
written notice to the Registrar.

          (f) TRANSFERS TO NON-QIB  INSTITUTIONAL  ACCREDITED  INVESTORS.  The
following  provisions  shall  apply  with  respect  to the  registration  of any
proposed  transfer of a Note to any Institutional  Accredited  Investor which is
not a QIB (excluding Non-U.S. Persons):

          (i) The Registrar shall register the transfer of any Note,  whether or
     not such Note bears the  Private  Placement  Legend,  if (x) the  requested
     transfer  is after the time period  referred  to in Rule  144(k)  under the
     Securities  Act as in  effect  with  respect  to such  transfer  or (y) the
     proposed  transferee  has  delivered  to the  Registrar  (A) a  certificate
     substantially  in the form of  Exhibit  F hereto  and (B) if the  aggregate
     principal  amount of the Notes being  transferred is less than Euro 100,000


                                       31
<PAGE>

     at the time of such  transfer,  an  Opinion of  Counsel  acceptable  to the
     Company that such transfer is in compliance with the Securities Act.

          (ii)  If  the  proposed  transferor  is  an  Agent  Member  holding  a
     beneficial  interest in a Restricted Global,  upon receipt by the Registrar
     and the Company of (x) the documents, if any, required by paragraph (i) and
     (y) instructions given in accordance with the relevant Depository's and the
     Registrar's  procedures,  the  Registrar  shall  reflect  on its  books and
     records the date and a decrease in the principal  amount of such Restricted
     Global  in an  amount  equal  to the  principal  amount  of the  beneficial
     interest in the Restricted Global to be transferred,  and the Company shall
     execute,  and the Trustee shall authenticate and deliver,  one or more U.S.
     Certificated Notes of like tenor and amount.

          SECTION 2.09. REPLACEMENT NOTES. If a mutilated Note is surrendered to
the Trustee or if the Holder  claims that the Note has been lost,  destroyed  or
wrongfully  taken, the Company shall issue and the Trustee shall  authenticate a
replacement  Note of like tenor and  principal  amount and  bearing a number not
contemporaneously  outstanding;  PROVIDED that the  requirements of this Section
2.09 and the  second  paragraph  of Section  2.10 are met.  If  required  by the
Trustee or the Company,  an indemnity  bond must be furnished that is sufficient
in the judgment of both the Trustee and the Company to protect the Company,  the
Trustee  or any  Agent  from any loss  that any of them may  suffer if a Note is
replaced.  The Company may charge such Holder for its  expenses and the expenses
of the Trustee in replacing a Note. In case any such mutilated,  lost, destroyed
or wrongfully  taken Note has become or is about to become due and payable,  the
Company  in its  discretion  may pay such Note  instead of issuing a new Note in
replacement thereof.

          Every replacement Note is an additional  obligation of the Company and
shall be entitled to the benefits of this Indenture.

          SECTION 2.10. OUTSTANDING NOTES. Notes outstanding at any time are all
Notes that have been  authenticated by the Trustee except for those cancelled by
it, those delivered to it for  cancellation  and those described in this Section
2.10 as not outstanding.

          If a Note is  replaced  pursuant  to  Section  2.09,  it  ceases to be
outstanding  unless  and  until  the  Trustee  and  the  Company  receive  proof
reasonably  satisfactory  to them that the replaced  Note is held by a BONA FIDE
purchaser.

          If the Paying  Agent  (other than the Company or an  Affiliate  of the
Company) holds on the maturity date or a redemption date money sufficient to pay
all principal,  premium,  if any, and interest payable on that date with respect
to the Notes (or portions  thereof) to be redeemed or payable on that date, then
on and after that date such Notes cease to be  outstanding  and interest on them
shall cease to accrue.

          A Note does not cease to be outstanding  because the Company or one of
its Affiliates holds such Note; PROVIDED,  HOWEVER, that, in determining whether


                                       32
<PAGE>

the Holders of the  requisite  principal  amount of the  outstanding  Notes have
given any request, demand,  authorization,  direction, notice, consent or waiver
hereunder, Notes owned by the Company or any other obligor upon the Notes or any
Affiliate  of the  Company or of such other  obligor  shall be  disregarded  and
deemed not to be  outstanding,  except that, in determining  whether the Trustee
shall be  protected  in relying upon any such  request,  demand,  authorization,
direction,  notice, consent or waiver, only Notes which a Responsible Officer of
the Trustee knows to be so owned shall be so  disregarded.  Notes so owned which
have been  pledged in good faith may be regarded as  outstanding  if the pledgee
establishes  to the  satisfaction  of the Trustee the pledgee's  right so to act
with  respect to such Notes and that the pledgee is not the Company or any other
obligor upon the Notes or any Affiliate of the Company or of such other obligor.

          SECTION 2.11.  TEMPORARY  NOTES.  Until definitive Notes are ready for
delivery,  the Company may prepare and the Trustee shall authenticate  temporary
Notes.  Temporary Notes shall be  substantially  in the form of definitive Notes
but  may  have  insertions,   substitutions,   omissions  and  other  variations
determined to be appropriate by the Officers  executing the temporary  Notes, as
evidenced by their  execution of such temporary  Notes.  If temporary  Notes are
issued,  the  Company  will  cause  definitive  Notes  to  be  prepared  without
unreasonable  delay.  After the preparation of definitive  Notes,  the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the  office  or  agency  of the  Company  designated  for such  purpose
pursuant to Section  4.02,  without  charge to the Holder.  Upon  surrender  for
cancellation of any one or more temporary  Notes,  the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Notes of authorized denominations.  Until so exchanged, the
temporary  Notes shall be entitled to the same benefits  under this Indenture as
definitive Notes.

          SECTION 2.12. CANCELLATION. The Company at any time may deliver to the
Trustee  for  cancellation  any Notes  previously  authenticated  and  delivered
hereunder which the Company may have acquired in any manner whatsoever,  and may
deliver to the  Trustee  for  cancellation  any Notes  previously  authenticated
hereunder  which the  Company  has not issued and sold.  The  Registrar  and the
Paying  Agent shall  forward to the Trustee  any Notes  surrendered  to them for
registration  of  transfer,  exchange,  purchase or payment.  The Trustee  shall
cancel all Notes surrendered for registration of transfer,  exchange,  purchase,
payment or  cancellation  and shall  return all such Notes to the  Company.  The
Company  shall not issue Notes to replace Notes it has paid in full or delivered
to the Trustee for cancellation.

          SECTION 2.13. CUSIP NUMBERS.  The Company in issuing the Notes may use
"CUSIP," "CINS," or "ISIN" numbers,  or common codes (if then generally in use),
as the case may be, in notices of  redemption  or exchange as a  convenience  to
Holders;  PROVIDED  that any such notice shall state that no  representation  is
made as to the  correctness of such numbers either as printed on the Notes or as
contained  in any notice of  redemption  or exchange  and that  reliance  may be
placed only on the other


                                       33
<PAGE>

identification  numbers printed on the Notes.  The Company shall promptly advise
the Trustee of any change in the CUSIP, CINS or ISIN numbers or common codes for
the Notes.

          SECTION 2.14. DEFAULTED INTEREST. If the Company defaults in a payment
of interest on the Notes,  it shall pay, or shall  deposit with the Paying Agent
money in immediately  available funds sufficient to pay, the defaulted interest,
plus (to the extent lawful) interest on the defaulted  interest,  to the Persons
who are Holders on a subsequent  special  record date. A special record date, as
used in this Section 2.14 with respect to the payment of any defaulted interest,
shall mean the 15th day next  preceding  the date fixed by the  Company  for the
payment of  defaulted  interest,  whether or not such day is a Business  Day. At
least 15 days before the subsequent  special record date, the Company shall mail
to each Holder and to the Trustee a notice  that states the  subsequent  special
record date, the payment date and the amount of defaulted interest to be paid.

          SECTION 2.15.  ISSUANCE OF ADDITIONAL  NOTES. The Company may, subject
to Article Four of this Indenture,  issue additional Notes under this Indenture.
The Notes  issued on the  Closing  Date and any  additional  Notes  subsequently
issued shall be treated as a single class for all purposes under this Indenture.

                                  ARTICLE THREE
                                   [RESERVED]



                                  ARTICLE FOUR
                                    COVENANTS

          SECTION  4.01.  PAYMENT OF NOTES.  The Company shall pay the principal
of,  premium,  if any,  and interest on the Notes on the dates and in the manner
provided in the Notes and this Indenture. An installment of principal,  premium,
if any, or interest  shall be considered  paid on the date due if the Trustee or
Paying  Agent  (other than the Company,  a  Subsidiary  of the  Company,  or any
Affiliate of any of them) holds on that date money designated for and sufficient
to pay the  installment.  If the Company or any Subsidiary of the Company or any
Affiliate of any of them,  acts as Paying Agent,  an  installment  of principal,
premium,  if any, or interest  shall be  considered  paid on the due date if the
entity  acting as Paying Agent  complies with the last sentence of Section 2.05.
As provided in Section 6.09,  upon any  bankruptcy or  reorganization  procedure
relative  to the  Company,  the  Trustee  shall  serve as the  Paying  Agent and
conversion agent, if any, for the Notes.

          The Company shall pay interest on overdue principal,  premium, if any,
and interest on overdue  installments of interest,  to the extent lawful, at the
rate per annum specified in the Notes.


                                       34

          SECTION  4.02.  MAINTENANCE  OF OFFICE OR  AGENCY.  The  Company  will
maintain an office or agency in the Borough of Manhattan,  the City of New York,
where Notes may be surrendered  for  registration of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Company in
respect of the Notes and this  Indenture  may be served.  The Company  will give
prompt  written  notice to the  Trustee of the  location,  and any change in the
location,  of such office or agency.  If at any time the  Company  shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof,  such presentations,  surrenders,  notices and demands
may be made or served at the address of the  Trustee set forth in Section  11.02
hereof.

          The  Company  may also from time to time  designate  one or more other
offices or agencies  (in or outside the City of New York) where the Notes may be
presented or surrendered  for any or all such purposes and may from time to time
rescind such designations; PROVIDED that no such designation or rescission shall
in any manner  relieve  the Company of its  obligation  to maintain an office or
agency in the Borough of Manhattan, the City of New York, for such purposes. The
Company will give prompt written  notice to the Trustee of any such  designation
or  rescission  and of any change in the  location  of any such other  office or
agency.

          The Company hereby initially  designates the Corporate Trust Office of
the Trustee,  located in the Borough of Manhattan, the City of New York, as such
office of the Company in  accordance  with  Section  2.04.  The  Company  hereby
initially  designates  the Euro Paying Agent as an office where the Regulation S
Global and European 144A Global may be surrendered for presentation for payment.

          SECTION 4.03.  LIMITATION ON  INDEBTEDNESS.  (a) The Company will not,
and  will  not  permit  any  of  its  Restricted   Subsidiaries  to,  Incur  any
Indebtedness  (other  than the Notes and  Indebtedness  existing  on the Closing
Date);  PROVIDED that the Company may Incur Indebtedness if, after giving effect
to the Incurrence of such  Indebtedness  and the receipt and  application of the
proceeds therefrom,  the Consolidated  Leverage Ratio would be greater than zero
and less than 6:1.

          Notwithstanding   the  foregoing,   the  Company  and  any  Restricted
Subsidiary (except as specified below) may Incur each and all of the following:

          (i)  Indebtedness  outstanding  at any time in an aggregate  principal
     amount not to exceed $100 million of  Indebtedness  that is PARI PASSU with
     or  subordinated  to the Notes and $150  million  of  Indebtedness  that is
     subordinated to the Notes, less any amount of such Indebtedness permanently
     repaid as provided under Section 4.11 hereof;

          (ii) Indebtedness owed (A) by any Restricted Subsidiary to the Company
     or another  Restricted  Subsidiary or (B) by the Company to any  Restricted
     Subsidiary;  PROVIDED that any event which  results in any such  Restricted
     Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer
     of such  Indebtedness  (other  than to the  Company or  another  Restricted
     Subsidiary)  shall be deemed,  in each case, to constitute an Incurrence of
     such Indebtedness not permitted by this clause (ii);


                                       35
<PAGE>

          (iii)  Indebtedness  issued in exchange  for,  or the net  proceeds of
     which are used to repay, redeem, defease, refinance, refund, extend, renew,
     replace,  discharge or otherwise retire any then  outstanding  Indebtedness
     (other than  Indebtedness  Incurred  under clause (i),  (ii),  (iv),  (vi),
     (viii), (xi) or (xii) of this paragraph) and any refinancings thereof in an
     amount not to exceed the amount so refinanced or refunded  (plus  premiums,
     penalties, accrued interest, fees and expenses); PROVIDED that Indebtedness
     the  proceeds  of which  are  used to  refinance  or  refund  the  Notes or
     Indebtedness  that is PARI PASSU with, or  subordinated in right of payment
     to, the Notes shall only be  permitted  under this  clause  (iii) if (A) in
     case the Notes are refinanced in part or the  Indebtedness to be refinanced
     is PARI PASSU with the Notes, such new Indebtedness, by its terms or by the
     terms  of  any  agreement  or   instrument   pursuant  to  which  such  new
     Indebtedness  is  outstanding,  is  expressly  made  PARI  PASSU  with,  or
     subordinate  in right of payment to, the remaining  Notes,  (B) in case the
     Indebtedness  to be refinanced is  subordinated  in right of payment to the
     Notes, such new Indebtedness, by its terms or by the terms of any agreement
     or instrument  pursuant to which such new Indebtedness is issued or remains
     outstanding, is expressly made subordinate in right of payment to the Notes
     at  least  to  the  extent  that  the  Indebtedness  to  be  refinanced  is
     subordinated to the Notes and (C) such new  Indebtedness,  determined as of
     the date of Incurrence of such new  Indebtedness,  does not mature prior to
     the Stated Maturity of the  Indebtedness to be refinanced or refunded,  and
     the  Average  Life  of such  new  Indebtedness  is at  least  equal  to the
     remaining  Average Life of the  Indebtedness  to be refinanced or refunded;
     and PROVIDED  FURTHER that in no event may  Indebtedness  of the Company be
     refinanced  by  means  of any  Indebtedness  of any  Restricted  Subsidiary
     pursuant to this clause (iii);

          (iv)  Indebtedness  (A) in  respect of  performance,  surety or appeal
     bonds  provided in the  ordinary  course of  business,  (B) under  Currency
     Agreements and Interest Rate Agreements;  PROVIDED that such agreements (a)
     are  designed  solely  to  protect  the  Company  or any of its  Restricted
     Subsidiaries  against  fluctuations in foreign  currency  exchange rates or
     interest  rates and (b) do not  increase  the  Indebtedness  of the obligor
     outstanding at any time other than as a result of  fluctuations  in foreign
     currency exchange rates or interest rates or by reason of fees, indemnities
     and  compensation  payable  thereunder,  and (C)  arising  from  agreements
     providing  for  indemnification,  adjustment  of purchase  price or similar
     obligations,  or from  Guarantees  or letters of  credit,  surety  bonds or
     performance  bonds  securing any  obligations  of the Company or any of its
     Restricted  Subsidiaries pursuant to such agreements,  in any case Incurred
     in connection  with the  disposition of any business,  assets or Restricted
     Subsidiary  (other than Guarantees of  Indebtedness  Incurred by any Person
     acquiring  all or any  portion  of  such  business,  assets  or  Restricted
     Subsidiary for the purpose of financing such  acquisition),  in a principal
     amount not to exceed the gross proceeds actually received by the Company or
     any Restricted Subsidiary in connection with such disposition;

          (v)  Indebtedness  of the  Company,  to the  extent  the net  proceeds
     thereof are  promptly  (A) used to purchase  Notes  tendered in an Offer to
     Purchase  made as a result  of a Change  in  Control  or (B)  deposited  to
     defease the Notes as described below under Article Eight hereof;


                                       36
<PAGE>

          (vi)  Guarantees of the Notes and  Guarantees of  Indebtedness  of the
     Company  by any  Restricted  Subsidiary  PROVIDED  the  Guarantee  of  such
     Indebtedness  is  permitted  by and made in  accordance  with  Section 4.07
     hereof;

          (vii) Indebtedness (including Guarantees) Incurred to finance the cost
     (including  the cost of  design,  development,  acquisition,  construction,
     installation,   improvement,  transportation  or  integration)  to  acquire
     equipment,  inventory or network assets  (including  acquisitions by way of
     Capitalized  Lease and  acquisitions  of the Capital Stock of a Person that
     becomes a Restricted  Subsidiary  to the extent of the fair market value of
     the equipment, inventory or network assets so acquired) by the Company or a
     Restricted Subsidiary after the Closing Date;

          (viii)  Indebtedness  of the  Company  not to exceed,  at any one time
     outstanding,  two times (A) the Net Cash  Proceeds  received by the Company
     after March 19, 1999 as a capital  contribution  or from the  issuance  and
     sale of its Capital Stock (other than Disqualified  Stock) to a Person that
     is not a  Subsidiary  of  the  Company,  to the  extent  (I)  such  capital
     contribution  or Net Cash  Proceeds  have not been used  pursuant to clause
     (C)(2) of the first  paragraph or clause (iii),  (iv), (vi) or (vii) of the
     second  paragraph of Section  4.04 hereof to make a Restricted  Payment and
     (II)  if  such  capital  contribution  or Net  Cash  Proceeds  are  used to
     consummate  a  transaction  pursuant to which the Company  Incurs  Acquired
     Indebtedness,  the amount of such Net Cash Proceeds exceeds one-half of the
     amount of Acquired  Indebtedness so Incurred and (B) 80% of the fair market
     value of property  (other than cash and cash  equivalents)  received by the
     Company after March 19, 1999 from the sale of its Capital Stock (other than
     Disqualified Stock) to a Person that is not a Subsidiary of the Company, to
     the extent (I) such capital  contribution  or sale of Capital Stock has not
     been used  pursuant  to clause  (iii),  (iv),  (vi) or (vii) of the  second
     paragraph of Section  4.04 hereof to make a Restricted  Payment and (II) if
     such  capital  contribution  or  Capital  Stock  is  used to  consummate  a
     transaction pursuant to which the Company Incurs Acquired Indebtedness, 80%
     of the fair market value of the property  received  exceeds one-half of the
     amount of Acquired Indebtedness so Incurred PROVIDED that such Indebtedness
     does not  mature  prior to the  Stated  Maturity  of the  Notes  and has an
     Average Life longer than the Notes;

          (ix) Acquired Indebtedness;

          (x) Strategic Subordinated Indebtedness;

          (xii)  Indebtedness  arising  from  the  honoring  by a bank or  other
     financial  institution  of a check,  or  similar  instrument  inadvertently
     (except in the case of  daylight  overdrafts)  drawn  against  insufficient
     funds in the ordinary course of business,  PROVIDED that such  Indebtedness
     is extinguished within three Business Days of Incurrence.


                                       37
<PAGE>

          (b) Notwithstanding  any other  provision of this Section 4.03,  the
maximum amount of Indebtedness  that the Company or a Restricted  Subsidiary may
Incur  pursuant to this Section  4.03 shall not be deemed to be  exceeded,  with
respect to any outstanding Indebtedness due solely to the result of fluctuations
in the exchange rates of currencies.

          (c) For   purposes  of   determining   any   particular   amount  of
Indebtedness under this Section 4.03, (1) 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 and (2) any Liens
granted pursuant to the equal and ratable provisions referred to in Section 4.09
shall not be treated as  Indebtedness.  For purposes of  determining  compliance
with this  Section  4.03,  in the event that an item of  Indebtedness  meets the
criteria of more than one of the types of Indebtedness  described in clauses (i)
through (xii) of Section 4.03(a),  the Company,  in its sole  discretion,  shall
classify,  and from time to time may reclassify,  such item of Indebtedness  and
only be required to include the amount and type of such  Indebtedness  in one of
such clauses.

          SECTION 4.04. LIMITATION ON RESTRICTED PAYMENTS. The Company will not,
and will not permit any Restricted Subsidiary to, directly or indirectly,

          (i) declare or pay any  dividend or make any  distribution  on or with
     respect to its Capital  Stock (other than (A)  dividends  or  distributions
     payable  solely in shares of its Capital  Stock  (other  than  Disqualified
     Stock) or in options,  warrants or other  rights to acquire  shares of such
     Capital Stock and (B) PRO RATA dividends or  distributions  on Common Stock
     of Restricted  Subsidiaries held by minority  stockholders) held by Persons
     other than the Company or any of its Restricted Subsidiaries,

          (ii)  purchase,  redeem,  retire or  otherwise  acquire  for value any
     shares of Capital  Stock of (A) the Company or an  Unrestricted  Subsidiary
     (including  options,  warrants  or other  rights to acquire  such shares of
     Capital Stock) held by any Person or (B) a Restricted Subsidiary (including
     options,  warrants or other rights to acquire such shares of Capital Stock)
     held by any Affiliate of the Company (other than a Wholly Owned  Restricted
     Subsidiary)  or any holder (or any  Affiliate of such holder) of 5% or more
     of the Capital Stock of the Company,

redeemed, prior to the Stated Maturity of the Notes), in each case except to the
extent such Net Cash Proceeds are used to Incur Indebtedness  pursuant to clause

     pursuant  to this  clause  does not  exceed $1  million  per annum plus the
     cumulative  amount of such per annum  limit not used in prior years and the
     cash proceeds from such  Investments,  PROVIDED that such proceeds are used
     within 180 days of the receipt thereof;

          (ix)  Investments  in permitted  Wholesale  Consortiums  and Permitted

included  in  calculating  whether  the  conditions  of clause  (C) of the first
paragraph  of this  Section  4.04 have been met with  respect to any  subsequent
Restricted  Payments.  In the event the proceeds of an issuance of Capital Stock

redemption, repurchase or other acquisition of Indebtedness.

          Any  Restricted  Payments  made in other  than cash shall be valued at

Guarantees,  in each case of or to the Company and its  Restricted  Subsidiaries
with respect to such Investment (up to the amount of such investment on the date

          SECTION 4.05.  LIMITATION  ON DIVIDEND AND OTHER PAYMENT  RESTRICTIONS
AFFECTING RESTRICTED SUBSIDIARIES. The Company will not, and will not permit any
Restricted Subsidiary to, create or otherwise cause or suffer to exist or become
effective any  consensual  encumbrance or restriction of any kind on the ability
of  any   Restricted   Subsidiary  to  (i)  pay  dividends  or  make  any  other
distributions  permitted  by  applicable  law  on  any  Capital  Stock  of  such
Restricted  Subsidiary owned by the Company or any other Restricted  Subsidiary,
(ii)  pay  any  Indebtedness  owed  to  the  Company  or  any  other  Restricted
Subsidiary,  (iii) make loans or advances to the Company or any other Restricted
Subsidiary  or (iv) transfer any of its property or assets to the Company or any
other Restricted Subsidiary.

          The  foregoing  provisions  shall not  restrict  any  encumbrances  or
restrictions:

          (i)  existing  on the  Closing  Date in this  Indenture  or any  other
     agreements in effect on the Closing Date, and any extensions, refinancings,


                                       41
<PAGE>

     renewals or replacements of such agreements; PROVIDED that the encumbrances
     and  restrictions  in  any  such  extensions,   refinancings,  renewals  or
     replacements  are no less favorable in any material  respect to the Holders
     than those  encumbrances or  restrictions  that are then in effect and that
     are being extended, refinanced, renewed or replaced;

          (ii) existing under or by reason of applicable law;

          (iii) existing with respect to any Person or the property or assets of
     such Person acquired by the Company or any Restricted Subsidiary,  existing
     at the time of such acquisition and not incurred in contemplation  thereof,
     which  encumbrances or restrictions are not applicable to any Person or the
     property or assets of any Person  other than such Person or the property or
     assets of such Person so acquired;

          (iv) in the case of clause (iv) of the first paragraph of this Section
     4.05, (A) that restrict in a customary manner the subletting, assignment or
     transfer of any property or asset that is a lease,  license,  conveyance or
     contract  or  similar  property  or asset,  (B)  existing  by virtue of any
     transfer of,  agreement  to  transfer,  option or right with respect to, or
     Lien on, any property or assets of the Company or any Restricted Subsidiary
     not otherwise  prohibited by this  Indenture or (C) arising or agreed to in
     the ordinary course of business, not relating to any Indebtedness, and that
     do not,  individually  or in the  aggregate,  detract  from  the  value  of
     property  or assets of the  Company  or any  Restricted  Subsidiary  in any
     manner material to the Company or any Restricted Subsidiary;

          (v) with respect to a Restricted Subsidiary and imposed pursuant to an
     agreement  that has been entered into for the sale or disposition of all or
     substantially  all of the Capital Stock of, or property and assets of, such
     Restricted Subsidiary;

          (vi)  contained  in the  terms of any  Indebtedness  or any  agreement
     pursuant to which such  Indebtedness  was issued if (A) the  encumbrance or
     restriction  applies  only in the event of a payment  default  or a default
     with  respect to a financial  covenant  contained in such  Indebtedness  or
     agreement,  (B) the  encumbrance  or  restriction  is not  materially  more
     disadvantageous to the Holders of the Notes than is customary in comparable
     financings  (as  determined by the Company) and (C) the Company  determines
     that any such  encumbrance  or restriction  will not materially  affect the
     Company's ability to make principal or interest payments on the Notes; or

          (vii) imposed in connection with a transaction described in clause (f)
     of the proviso to the  definition of "Asset Sale" and relating  solely to a
     Restricted  Subsidiary that transfers  assets to the special purpose entity
     referred to therein;  PROVIDED  that the Company  determines  that any such
     encumbrance or restriction will not materially affect the Company's ability
     to make principal or interest payments on the Notes.

Nothing  contained  in this  Section  4.05  shall  prevent  the  Company  or any
Restricted  Subsidiary  from (1) creating,  incurring,  assuming or suffering to
exist any Liens  otherwise  permitted in Section 4.09 hereof or (2)  restricting


                                       42
<PAGE>

the sale or other disposition of property or assets of the Company or any of its
Restricted  Subsidiaries  that secure  Indebtedness of the Company or any of its
Restricted Subsidiaries.

          SECTION 4.06.  LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF
RESTRICTED  SUBSIDIARIES.  The  Company  will not sell,  and will not permit any
Restricted Subsidiary,  directly or indirectly,  to issue or sell, any shares of

rights to purchase  shares of such Capital Stock) except (i) to the Company or a
Wholly Owned  Restricted  Subsidiary;  (ii)  issuances of director's  qualifying
shares or sales to  foreign  nationals  of shares of  Capital  Stock of  foreign
Restricted  Subsidiaries,  to the extent  required by applicable  law; (iii) if,
immediately  after  giving  effect to such  issuance  or sale,  such  Restricted
Subsidiary would no longer constitute a Restricted Subsidiary and any Investment
in such Person remaining after giving effect to such issuance or sale would have
been  permitted to be made under Section 4.04 hereof if made on the date of such
issuance or sale; (iv) a pledge or hypothecation of or Lien on any Capital Stock
of a Subsidiary to the extent not prohibited  under Section 4.09 hereof;  or (v)
sales by the Company or Restricted  Subsidiaries of Common Stock of a Restricted
Subsidiary,  PROVIDED that the Company or such Restricted Subsidiaries apply the
Net Cash Proceeds, if any, of any such sale in accordance with clause (A) or (B)
of Section 4.11 hereof.

          SECTION  4.07.  LIMITATION  ON ISSUANCES OF  GUARANTEES  BY RESTRICTED
SUBSIDIARIES. The Company will not permit any Restricted Subsidiary, directly or
indirectly,  to Guarantee  any  Indebtedness  of the Company which is PARI PASSU
with  or   subordinate   in  right  of   payment   to  the  Notes   ("Guaranteed
Indebtedness"),  unless (i) such Restricted Subsidiary  simultaneously  executes
and  delivers  a  supplemental  indenture  to  this  Indenture  providing  for a
Guarantee (a "Subsidiary  Guarantee") of payment of the Notes by such Restricted
Subsidiary  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;  PROVIDED that this paragraph shall
not be applicable to any Guarantee of any Restricted  Subsidiary that existed at
the time such Person  became a  Restricted  Subsidiary  and was not  Incurred in
connection  with,  or in  contemplation  of, such Person  becoming a  Restricted
Subsidiary.  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.

          Notwithstanding   the  foregoing,   any  Subsidiary   Guarantee  by  a
Restricted  Subsidiary  may 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 Company's
and each Restricted  Subsidiary's  Capital Stock in, or all or substantially all
the assets of, such Restricted  Subsidiary (which sale,  exchange or transfer is


                                       43
<PAGE>

not  prohibited  by 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  4.08.   LIMITATION  ON  TRANSACTIONS  WITH  SHAREHOLDERS  AND
AFFILIATES.  The Company will not, and will not permit any Restricted Subsidiary
to,  directly  or  indirectly,  enter  into,  renew or  extend  any  transaction
(including,  without  limitation,  the  purchase,  sale,  lease or  exchange  of
property or assets,  or the  rendering of any  service)  with any holder (or any
Affiliate  of such  holder) of 5% or more of any class of  Capital  Stock of the
Company  or with any  Affiliate  of the  Company or any  Restricted  Subsidiary,
except upon fair and  reasonable  terms no less favorable to the Company or such
Restricted  Subsidiary than could be obtained,  at the time of such  transaction
or, if such transaction is pursuant to a written  agreement,  at the time of the
execution of the  agreement  providing  therefor,  in a comparable  arm's-length
transaction with a Person that is not such a holder or an Affiliate.

          The foregoing limitation does not limit, and shall not apply to:

          (i)  transactions  (A)  approved  by a majority  of the  disinterested
     members  of the  Board of  Directors  or (B) for  which  the  Company  or a
     Restricted  Subsidiary  delivers  to the  Trustee  a written  opinion  of a
     nationally  recognized investment banking firm stating that the transaction
     is fair to the Company or such Restricted Subsidiary from a financial point
     of view;

          (ii)  any  transaction  solely  between  the  Company  and  any of its
     Restricted Subsidiaries or solely between Restricted Subsidiaries;

          (iii)  the  payment  of  reasonable  and  customary  regular  fees  to
     directors of the Company who are not employees of the Company;

          (iv) any payments or other  transactions  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;

          (v)  compensation,  indemnification  and other  benefits  paid or made
     available to officers,  directors and  employees in the ordinary  course of
     business in connection with services  actually rendered and consistent with
     past practice;

          (vi)   transactions  in  accordance  with  the  Existing   Stockholder
     Agreements as in effect on March 19, 1999; or

          (vii) any Restricted Payments not prohibited by Section 4.04 hereof.

Notwithstanding the foregoing, any transaction or series of related transactions
covered by the first  paragraph  of this Section 4.08 and not covered by clauses
(ii) through (v) of this paragraph,  the aggregate  amount of which exceeds $2.0
million  in value,  must be  approved  or  determined  to be fair in the  manner
provided for in clause (i)(A) or (B) of this Section 4.08.

          SECTION 4.09.  LIMITATION ON LIENS. The Company will not, and will not
permit any Restricted  Subsidiary to, create,  incur,  assume or suffer to exist
any Lien on any of its assets or properties of any character (including, without
limitation,  licenses),  or any shares of Capital Stock or  Indebtedness  of any
Restricted  Subsidiary,  without making effective provision for all of the Notes
and all other amounts due under this  Indenture to be directly  secured  equally
and ratably with (or, if the  obligation or liability to be secured by such Lien
is  subordinated  in right of payment to the Notes,  prior to) the obligation or
liability secured by such Lien.

          The foregoing limitation does not apply to:

          (i) Liens existing on the Closing Date;

          (ii) Liens  granted  after the  Closing  Date on any assets or Capital
     Stock of the Company or its Restricted Subsidiaries created in favor of the
     Holders;

          (iii)  Liens with  respect to the  assets of a  Restricted  Subsidiary
     granted by such  Restricted  Subsidiary  to the  Company or a Wholly  Owned
     Restricted  Subsidiary to secure  Indebtedness owing to the Company or such
     other Restricted Subsidiary;

          (iv) Liens securing Indebtedness permitted to be Incurred under clause
     (iii) of the second  paragraph  of Section 4.03 hereof which is Incurred to
     refinance secured  Indebtedness;  PROVIDED that such Liens do not extend to
     or cover any property or assets of the Company or any Restricted Subsidiary
     other  than  the  property  or  assets  securing  the  Indebtedness   being
     refinanced;

          (v) Liens on the  Capital  Stock of, or any  property  or assets of, a
     Restricted  Subsidiary securing  Indebtedness of such Restricted Subsidiary
     permitted under Section 4.03 hereof;

          (vi) Liens on the Capital Stock of Restricted  Subsidiaries that own a
     substantial  portion of assets  financed with  Indebtedness  Incurred under
     clause  (vii) of  Section  4.03  hereof,  if such  liens  secure  only such
     Indebtedness; or

          (vii) Permitted Liens.

          SECTION 4.10. LIMITATION ON SALE-LEASEBACK  TRANSACTIONS.  The Company
will not,  and will not  permit any  Restricted  Subsidiary  to,  enter into any
sale-leaseback transaction involving any of its assets or properties whether now
owned or  hereafter  acquired,  whereby the Company or a  Restricted  Subsidiary
sells or transfers such assets or properties and then or thereafter  leases such
assets or properties or any part thereof or any other assets or properties which
the Company or such  Restricted  Subsidiary,  as the case may be, intends to use
for  substantially the same purpose or purposes as the assets or properties sold
or transferred; PROVIDED that a sale-leaseback


                                       45
<PAGE>

transaction  shall not include any lease in connection with which the Company or
a  Restricted  Subsidiary  acquires  assets or property in  anticipation  of the
substantially contemporaneous sale or transfer to the lessor under such lease.

          The  foregoing  restriction  does  not  apply  to  any  sale-leaseback
transaction if:

          (i) the lease is for a period,  including  renewal  rights,  of not in
     excess of three years;

          (ii) the lease secures or relates to  industrial  revenue or pollution
     control bonds;

          (iii) the transaction is solely between the Company and any Restricted
     Subsidiary or solely between Restricted Subsidiaries; or

          (iv) the Company or such Restricted Subsidiary, within 12 months after
     the sale or transfer of any assets or properties  is completed,  applies an
     amount not less than the net proceeds received from such sale in accordance
     with clause (A) or (B) of the first paragraph of Section 4.11 hereof.

          SECTION  4.11.  LIMITATION  ON ASSET SALES.  The Company will not, and
will not permit any Restricted  Subsidiary to, consummate any Asset Sale, unless
(i) the consideration  received by the Company or such Restricted  Subsidiary is
at least  equal to the fair  market  value of the assets sold or disposed of and
(ii) at least 75% of the  consideration  received  consists of cash or Temporary
Cash  Investments.  In the event and to the  extent  that the Net Cash  Proceeds
received by the Company or any of its Restricted  Subsidiaries  from one or more
Asset  Sales  occurring  on or  after  the  Closing  Date  in any  period  of 12
consecutive  months  exceed 10% of Adjusted  Consolidated  Net  Tangible  Assets
(determined as of the date closest to the  commencement  of such 12-month period
for which a consolidated  balance sheet of the Company and its  Subsidiaries has
been filed  with the  Commission  pursuant  to Section  4.18  hereof),  then the
Company shall or shall cause the relevant Restricted Subsidiary to (i) within 12
months  after the date Net Cash  Proceeds  so  received  exceed 10% of  Adjusted
Consolidated Net Tangible  Assets,  (A) apply an amount equal to such excess Net
Cash Proceeds to permanently repay  unsubordinated  Indebtedness of the Company,

applied) during such 12-month period as set forth in clause (i) of the preceding
sentence  and  not  applied  as so  required  by the end of  such  period  shall
constitute "EXCESS PROCEEDS."

          If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 totals at least $10 million,  the Company must commence,  not later
than the  fifteenth  Business  Day of such  month,  and  consummate  an Offer to
Purchase from the Holders on a PRO RATA basis an aggregate  principal  amount of

existence and the existence of each of its Restricted Subsidiaries in accordance
with the  respective  organizational  documents  of the  Company  and each  such

(whether pursuant to charter,  partnership  certificate,  agreement,  statute or
otherwise),  material  licenses  and  franchises  of the  Company  and each such
Subsidiary; PROVIDED that the Company shall not be required to preserve any such
right, license or franchise,  or the existence of any Restricted Subsidiary,  if

the business of the Company and its Restricted Subsidiaries taken as a whole.

          SECTION 4.14.  PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay
or discharge and shall cause each of its  Subsidiaries  to pay or discharge,  or

the  Company  or any such  Subsidiary,  (b) the  income or  profits  of any such
Subsidiary which is a corporation or (c) the property of the Company or any such

good  condition,  repair and working order (ordinary wear and tear excepted) and
supplied  with all  necessary  equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Company may be necessary so that the business  carried on in
connection therewith may be properly and advantageously  conducted at all times;
PROVIDED that nothing in this Section 4.15 shall prevent the Company or any such
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 Company,  desirable in the conduct of the business of the
Company or such Subsidiary.

          The Company will  provide or cause to be provided,  for itself and its
Restricted  Subsidiaries,   insurance  (including  appropriate   self-insurance)
against loss or damage of the kinds customarily  insured against by corporations
similarly  situated and owning like properties,  with reputable insurers or with
the government of the United States of America,  or an agency or instrumentality
thereof, in such amounts,  with such deductibles and by such methods as shall be
customary  for  corporations  similarly  situated  in the  industry in which the
Company or such  Restricted  Subsidiary,  as the case may be, is then conducting
business.

          SECTION  4.16.  NOTICE  OF  DEFAULTS.  In the event  that the  Company

such obligation, specifying each such default and the nature and status thereof.
The  Company  shall also  notify the  Trustee of any  default or defaults in the

Offer (as defined in the Registration  Rights Agreement) or the effectiveness of
a Shelf Registration Statement (as defined in the Registration Rights Agreement)
(the  "REGISTRATION") and (ii) the date that is 180 days after the Closing Date,
in either case, whether or not the Company is then required to file reports with
the  Commission,  the  Company  shall  file with the  Commission  (to the extent
accepted by the Commission) all such reports


                                       48

Sections  13(a) or 15(d) under the  Securities  Exchange  Act of 1934 if it were
subject  thereto.  The Company shall supply the Trustee and each Holder or shall
supply to the Trustee for  forwarding to each such Holder,  without cost to such

Holder of the Notes  quarterly and annual  reports  substantially  equivalent to
those which would be required by the  Exchange  Act. In  addition,  at all times
prior to the  Registration,  upon the  request of any Holder or any  prospective
purchaser of the Notes designated by a Holder,  the Company shall supply to such
Holder or such  prospective  purchaser the information  required under Rule 144A
under the Securities Act.

          Delivery of such reports,  information and documents to the Trustee is
for  informational  purposes  only and the  Trustee's  receipt of such shall not
constitute   constructive  notice  of  any  information   contained  therein  or
determinable  from  information  contained  therein,   including  the  Company's
compliance  with any of its  covenants  hereunder  (as to which the  Trustee  is
entitled to rely exclusively on Officers' Certificates).

          SECTION  4.19.  WAIVER OF STAY,  EXTENSION OR USURY LAWS.  The Company
covenants  (to the extent  that it may  lawfully  do so) that it will not at any
time  insist  upon,  or 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
that would prohibit or forgive the Company from paying all or any portion of the
principal of, premium, if any, or interest on the Notes as contemplated  herein,
wherever enacted,  now or at any time hereafter in force, or that 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 will  not  hinder,  delay  or  impede  the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

entirety or  substantially an entirety in one transaction or a series of related
transactions)  to,  any  Person or permit  any  Person to merge with or into the
Company unless:

          (i) the  Company  shall be the  continuing  Person,  or the Person (if
     other  than the  Company)  formed by such  consolidation  or into which the
     Company is merged or that  acquired or leased such  property  and assets of
     the Company shall be a corporation organized and validly existing under the
     laws of the United States of America or any jurisdiction  thereof and shall


                                       49

          (ii) immediately after giving effect to such  transaction,  no Default

     Consolidated   Net  Worth  of  the  Company   immediately   prior  to  such
     transaction;

          (iv)  immediately  after giving  effect to such  transaction  on a PRO
     FORMA basis, the Company,  or any Person becoming the successor  obligor of
     the Notes,  as the case may be, could Incur at least $1.00 of  Indebtedness
     under the first paragraph of Section 4.03 hereof; PROVIDED that this clause
     (iv) shall not apply to (1) a consolidation, merger or sale of all (but not
     less than all) of the assets of the  Company if all Liens and  Indebtedness
     of the Company or any Person  becoming the successor  obligor on the Notes,
     as the case may be, and its Restricted Subsidiaries outstanding immediately
     after such transaction would, if Incurred at such time, have been permitted
     to be Incurred (and all such Liens and  Indebtedness,  other than Liens and
     Indebtedness  of the Company and its  Restricted  Subsidiaries  outstanding
     immediately  prior  to the  transaction,  shall  be  deemed  to  have  been
     Incurred) for all purposes of this Indenture or (2) a consolidation, merger
     or  sale of all or  substantially  all of the  assets  of the  Company  if,
     immediately  after giving effect to such  transaction on a PRO FORMA basis,

     clauses  (iii) and (iv) of this  Section  5.01) and Opinion of Counsel,  in
     each case  stating  that such  consolidation,  merger or transfer  and such
     supplemental indenture complies with this provision and that all conditions
     precedent  provided  for  herein  relating  to such  transaction  have been
     complied with;

PROVIDED, HOWEVER, that clauses (iii) and (iv) of this Section 5.01 do not apply
if,  in  the  good  faith  determination  of  the  Board  of  Directors,   whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such  transaction is to change the state of  incorporation  of the Company;  and
PROVIDED FURTHER that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

          SECTION 5.02. SUCCESSOR SUBSTITUTED. Upon any consolidation or merger,
or any sale,  conveyance,  transfer or other disposition of all or substantially
all of the property and assets of the Company in accordance with Section 5.01 of

the  Company  is merged or to which  such sale,  conveyance,  transfer  or other

                              DEFAULT AND REMEDIES

          SECTION  6.01.  EVENTS OF DEFAULT.  An "EVENT OF DEFAULT"  shall occur

     upon acceleration, redemption or otherwise;

          (b) the  Company  defaults in the payment of interest on any Note when
     the same becomes due and payable,  and such default  continues for a period
     of 30  days;  PROVIDED  that a  failure  to  make  any of the  first  three
     scheduled interest payments on the Notes in a timely manner will constitute

          (c)  the  Company  defaults  in  the  performance  or  breach  of  the
     provisions  of Article Five hereof or fails to make or  consummate an Offer

     issues of all such Persons,  whether such  Indebtedness now exists or shall
     hereafter  be created,  (I) an event of default  that has caused the holder
     thereof to declare  such  Indebtedness  to be due and payable  prior to its
     Stated  Maturity and such  Indebtedness  has not been discharged in full or
     such acceleration has not been rescinded or annulled within 30 days of such
     acceleration  and/or (II) 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 30 days of such  payment
     default;

          (f) any final  judgment or order (not  covered by  insurance)  for the
     payment  of money in excess of $10  million in the  aggregate  for all such
     final   judgments  or  orders  against  all  such  Persons   (treating  any
     deductibles,  self-insurance  or  retention  as not so  covered)  shall  be
     rendered against the Company or any Significant Subsidiary and shall not be
     paid or discharged,  and there shall be any period of 60  consecutive  days
     following  entry of the final  judgment or order that causes the  aggregate


                                       51
<PAGE>

     order  for  (A)  relief  in  respect  of the  Company  or  any  Significant
     Subsidiary  in  an  involuntary  case  under  any  applicable   bankruptcy,
     insolvency or other similar law now or hereafter in effect, (B) appointment
     of a receiver,  liquidator,  assignee,  custodian, trustee, sequestrator or
     similar official of the Company or any Significant Subsidiary or for all or
     substantially  all  of the  property  and  assets  of  the  Company  or any
     Significant  Subsidiary or (C) the winding up or liquidation of the affairs
     of the Company or any Significant Subsidiary and, in each case, such decree

     assets of the  Company or any  Significant  Subsidiary  or (C)  effects any
     general assignment for the benefit of creditors.

          SECTION  6.02.  ACCELERATION.  If an Event of Default  (other  than an
Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with
respect to the  Company)  occurs and is  continuing  under this  Indenture,  the
Trustee or the  Holders  of at least 25% in  aggregate  principal  amount of the
Notes then outstanding,  by written notice to the Company (and to the Trustee if
such  notice is given by the  Holders),  may,  and the Trustee at the request of
such  Holders  shall,  declare the  principal  amount of,  premium,  if any, and
accrued  interest  on the  Notes  to be  immediately  due  and  payable.  Upon a
declaration of  acceleration,  such principal  amount of,  premium,  if any, and
accrued  interest  shall  be  immediately  due and  payable.  In the  event of a
declaration of acceleration  because an Event of Default set forth in clause (e)
of Section 6.01 has occurred and is continuing, such declaration of acceleration
shall be automatically rescinded and annulled if the event of default triggering
such Event of Default  pursuant  to clause (e) shall be remedied or cured by the
Company or the relevant  Significant  Subsidiary or waived by the holders of the
relevant  Indebtedness within 60 days after the declaration of acceleration with
respect  thereto.  If an Event of  Default  specified  in  clause  (g) or (h) of
Section  6.01 occurs  with  respect to the  Company,  the  principal  amount of,
premium,  if any, and accrued interest on the Notes then outstanding  shall IPSO
FACTO become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder.

          The  Holders  of at  least  a  majority  in  principal  amount  of the
outstanding  Notes,  by written  notice to the Company and to the  Trustee,  may
waive all past defaults and rescind and annul a declaration of acceleration  and
its  consequences  if (i)  all  existing  Events  of  Default,  other  than  the


                                       52
<PAGE>

nonpayment of the principal of, premium,  if any, and interest on the Notes that
have become due solely by such declaration of  acceleration,  have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction.

          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,  premium,  if any, or interest
on the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

          The Trustee may maintain a proceeding  even if it does not possess any
of the Notes or does not produce any of them in the proceeding.

          SECTION 6.04. WAIVER OF PAST DEFAULTS. Subject to Section 9.02, at any
time after such a declaration of  acceleration,  but before a judgment or decree
for the payment of the money due has been  obtained by the Trustee,  the Holders
of at least a majority in aggregate principal amount of the outstanding Notes by
written notice to the Company and to the Trustee may waive all past Defaults and
rescind and annul a declaration of acceleration and its  consequences  (except a
Default in the payment of principal of premium,  if any, or interest on any Note
as  specified  in clause (a) or (b) of Section 6.01 (but not as a result of such
acceleration)  or in respect of a covenant or provision of this Indenture  which
cannot  be  modified  or  amended  without  the  consent  of the  Holder of each
outstanding Note affected) if (i) all existing Events of Default, other than the
nonpayment  of the  principal  amount of,  premium,  if any, and interest on the
Notes that have become due solely by such declaration of acceleration, have been
cured or waived and (ii) the rescission  would not conflict with any judgment or
decree of a court of competent jurisdiction.  Upon any such waiver, such Default
shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been  cured,  for every  purpose of this  Indenture;  but no such waiver
shall extend to any  subsequent  or other  Default or Event of Default or impair
any right consequent thereto.

          SECTION 6.05. CONTROL BY MAJORITY.  The Holders of at least a majority
in  aggregate  principal  amount of the  outstanding  Notes 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 the Trustee.  However, the
Trustee  may  refuse to follow any  direction  that  conflicts  with law or this
Indenture,  that may  involve the  Trustee in  personal  liability,  or that the
Trustee  determines  in good  faith may be unduly  prejudicial  to the rights of
Holders of the Notes,  not joining in the giving of such  direction and may take
any  other  action  it  deems  proper  that is not  inconsistent  with  any such
direction received from Holders of the Notes.

          SECTION 6.06.  LIMITATION ON SUITS. A Holder may not pursue any remedy
with respect to this Indenture or the Notes unless:


                                       53
<PAGE>

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

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

          (iii) such Holder or Holders offer the Trustee indemnity  satisfactory
     to the Trustee against any costs, liability or expense;

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

          (v) during such 60-day period,  the Holders of a majority in aggregate
     principal  amount  of the  outstanding  Notes  do not give  the  Trustee  a
     direction that is inconsistent with the request.

          For purposes of Section 6.05 of this  Indenture and this Section 6.06,
the Trustee shall comply with TIA Section 316(a) in making any  determination of
whether the Holders of the required  aggregate  principal  amount of outstanding
Notes have  concurred  in any request or  direction of the Trustee to pursue any
remedy available to the Trustee or the Holders with respect to this Indenture or
the Notes or otherwise under the law.

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

          SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE  PAYMENT.  Notwithstanding
any other  provision  of this  Indenture,  the right of any  Holder of a Note to
receive payment of principal of,  premium,  if any, or interest on such Holder's
Note on or after the  respective  due dates  expressed on such Note, 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 such Holder.

          SECTION 6.08.  COLLECTION  SUIT BY TRUSTEE.  If an Event of Default in
payment of  principal,  premium or  interest  specified  in clause (a) or (b) of
Section 6.01 of this Indenture occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express  trust against the Company
or any other obligor of the Notes for the whole amount of principal, premium, if
any, and accrued interest  remaining  unpaid,  together with interest on overdue
principal,  premium, if any, and, to the extent that payment of such interest is
lawful,  interest on overdue installments of interest,  in each case at the rate
specified in the Notes,  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, and
any other amounts due the Trustee under Section 7.07 hereof.

          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 any other  amounts due the Trustee  under
Section 7.07) and the Holders  allowed in any judicial  proceedings  relative to
the Company (or any other  obligor of the Notes),  its creditors or its property
and the  Trustee  shall be  entitled  and  empowered  to collect and receive any
monies,  securities or other property  payable or deliverable upon conversion or
exchange of the Notes or upon any such claims and to  distribute  the same,  and
any custodian,  receiver, assignee, trustee,  liquidator,  sequestrator or other
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder 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 Holders,  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 empower the Trustee to  authorize or consent to, or accept or adopt on
behalf of any Holder,  any plan of  reorganization,  arrangement,  adjustment or
composition  affecting  the Notes or the  rights of any  Holder  thereof,  or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

          SECTION 6.10.  PRIORITIES.  If the Trustee collects any money pursuant
to this Article Six, it shall pay out the money in the following order:

          FIRST: to the Trustee for all amounts due under Section 7.07;

          SECOND:  to Holders for amounts then due and unpaid for  principal of,
     premium,  if any,  and interest on the Notes in respect of which or for the
     benefit of which such money has been collected, ratably, without preference
     or priority of any kind,  according  to the amounts due and payable on such
     Notes for principal, premium, if any, 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 Holders 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 may require any party
litigant in such suit to file an  undertaking  to pay the costs of the suit, and
the court 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 does not apply


                                       55
<PAGE>

to a suit by the  Trustee,  a suit by a Holder  pursuant to Section 6.07 of this
Indenture,  or a suit by  Holders  of more than 10% in  principal  amount of the
outstanding Notes.

          SECTION 6.12.  RESTORATION  OF RIGHTS AND REMEDIES.  If the Trustee or
any Holder has  instituted  any  proceeding to enforce any right or remedy under
this Indenture and such  proceeding has been  discontinued  or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then,
and in every such case,  subject to any  determination in such  proceeding,  the
Company,   the  Trustee  and  the  Holders  shall  be  restored   severally  and
respectively to their former  positions  hereunder and thereafter all rights and
remedies of the Company, the Trustee and the Holders shall continue as though no
such proceeding had been instituted.

          SECTION  6.13.  RIGHTS AND  REMEDIES  CUMULATIVE.  Except as otherwise
provided with respect to the  replacement  or payment of  mutilated,  destroyed,
lost or  wrongfully  taken  Notes in  Section  2.09,  no right or remedy  herein
conferred  upon or  reserved  to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent  permitted by law, be cumulative and in addition to every other right and
remedy  given  hereunder  or now or  hereafter  existing  at law or in equity or
otherwise.  The  assertion or employment  of any right or remedy  hereunder,  or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          SECTION  6.14.  DELAY OR OMISSION NOT WAIVER.  No delay or omission of
the Trustee or of any Holder to exercise any right or remedy  accruing  upon any
Event of Default shall impair any such right or remedy or constitute a waiver of
any such Event of Default or an  acquiescence  therein.  Every  right and remedy
given by this  Article  Six or by law to the  Trustee or to the  Holders  may be
exercised  from time to time,  and as often as may be deemed  expedient,  by the
Trustee or by the Holders, as the case may be.

                                  ARTICLE SEVEN
                                     TRUSTEE

          SECTION 7.01. GENERAL.  The duties and responsibilities of the Trustee
shall be as provided  by the TIA and as set forth  herein.  Notwithstanding  the
foregoing, no provision of this Indenture 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 in the  exercise  of any of its  rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate  indemnity  against such risk or  liability is not  reasonably
assured to it. Whether or not therein expressly so provided,  every provision of
this  Indenture  relating  to the  conduct  or  affecting  the  liability  of or
affording  protection to the Trustee shall be subject to the  provisions of this
Article Seven.

          SECTION  7.02.  CERTAIN  RIGHTS OF  TRUSTEE.  Subject to TIA  Sections
315(a) through (d):

          (i) the Trustee may conclusively rely and shall be protected in acting
     or  refraining  from acting upon any  resolution,  certificate,  statement,
     instrument,  opinion, report, notice, request,  direction,  consent, order,
     bond,  debenture,  note,  other evidence of  indebtedness or other paper or
     document  (whether in its original or facsimile  form) 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 and
     may in good faith  conclusively  rely as to the truth of the statements and
     the correctness of the opinions therein;

          (ii) before the Trustee acts or refrains  from acting,  it may require
     an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be
     liable for any  action it takes or omits to take in good faith in  reliance
     on such certificate, opinion and/or an accountants' certificate if required
     under the TIA;

          (iii) the Trustee may act through its  attorneys  and agents and shall
     not be responsible  for the misconduct or negligence of any agent appointed
     with due care;

          (iv) the Trustee  shall be under no  obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the  Holders,  unless  such  Holders  shall  have  offered to the
     Trustee  security or indemnity  reasonably  satisfactory  to it against the
     costs,  expenses and liabilities  that might be incurred by it in complying
     with such request or direction;

          (v) the  Trustee  shall not be liable for any action it takes or omits
     to take in good  faith  that it  believes  to be  authorized  or within its
     rights or powers or for any action it takes or omits to take in  accordance
     with the direction of the Holders of a majority in principal  amount of the
     outstanding  Notes relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred upon the Trustee,  under this  Indenture;  PROVIDED that
     the Trustee's conduct does not constitute negligence or bad faith;

          (vi)  whenever in the  administration  of this  Indenture  the Trustee
     shall deem it  desirable  that a matter be proved or  established  prior to
     taking,  suffering  or omitting to take any action  hereunder,  the Trustee
     (unless  other  evidence  be herein  specifically  prescribed)  may, in the
     absence of bad faith on its part, rely upon an Officers' Certificate;

          (vii) 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  at the sole cost of the  Company to examine  the books,


                                       57
<PAGE>

     records and premises of the Company  personally or by agent or attorney and
     shall incur no liability or  additional  liability of any kind by reason of
     such inquiry or investigation;

          (viii) the Trustee shall not be charged with  knowledge of any Default
     or Event of Default,  the identity of any  Restricted  Subsidiary or of the
     existence  of any  Change of  Control  or Asset  Sale  unless  either (i) a
     Responsible  Officer  shall  have  actual  knowledge  thereof,  or (ii) the
     Trustee shall have received  written notice thereof from the Company or any
     Holder of the Notes; and

          (ix) the Trustee may consult  with  counsel of its  selection  and the
     advice of such counsel or any Opinion of Counsel shall be full and complete
     authorization  and  protection in respect of any action taken,  suffered or
     omitted to be taken by it hereunder in good faith and in reliance thereon.

          SECTION  7.03.  INDIVIDUAL  RIGHTS OF  TRUSTEE.  The  Trustee,  in its
individual or any other  capacity,  may become the owner or pledgee of Notes and
may otherwise  deal with the Company or its  Affiliates  with the same rights it
would  have if it were not the  Trustee.  Any  Agent  may do the same  with like
rights. However, the Trustee is subject to TIA Sections 310(b) and 311.

          SECTION  7.04.  TRUSTEE'S   DISCLAIMER.   The  Trustee  (a)  makes  no
representation  as to the  validity or adequacy of this  Indenture or the Notes,
(b)  shall  not be  accountable  for the  Company's  use or  application  of the
proceeds of the Notes and (c) shall not be responsible  for any statement in the
Notes other than its certificate of authentication.

          SECTION  7.05.  NOTICE  OF  DEFAULT.  If any  Default  or any Event of
Default  occurs  and is  continuing  and if such  Default or Event of Default is
known to a  Responsible  Officer of the Trustee,  the Trustee shall mail to each
Holder in the manner and to the extent  provided in TIA Section 313(c) notice of
the  Default or Event of Default  within 90 days  after it occurs,  unless  such
Default or Event of Default has been cured;  PROVIDED,  HOWEVER, that, except in
the case of a default in the payment of the  principal of,  premium,  if any, or
interest on any Note, the Trustee shall be protected in withholding  such notice
if and as long as the board of  directors,  the  executive  committee or a trust
committee of directors and/or Responsible  Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Holders.
If an Event of Default has occurred and is continuing, the Trustee shall use the
same degree of care and skill in its exercise of the rights and powers  invested
in it under  this  Indenture  as a  prudent  person  would  exercise  under  the
circumstances in the conduct of such person's own affairs.


                                       58
<PAGE>

          SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after each
May 15,  beginning  with May 15, 2000,  the Trustee shall mail to each Holder as
provided in TIA Section  313(c) a brief  report that  complies  with TIA Section
313(a) dated as of such May 15, if required by TIA Section 313(a).

          SECTION 7.07. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee such  compensation  as shall be agreed upon from time to time in writing
for its services.  The  compensation  of the Trustee 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 out-of-pocket expenses and
advances  incurred  or made by the  Trustee.  Such  expenses  shall  include the
reasonable compensation and expenses of the Trustee's agents and counsel.

          The Company shall  indemnify the Trustee and any  predecessor  trustee
for, and hold it harmless against,  any and all loss, claim, damage or liability
or  expense  (including  taxes  other  than  taxes  based upon the income of the
Trustee and  reasonable  compensation  and expenses of the Trustee's  agents and
counsel)  incurred  by it  without  negligence  or  bad  faith  on its  part  in
connection  with the  acceptance  or  administration  of this  Indenture and its
duties under this  Indenture and the Notes,  including the costs and expenses of
defending  itself  against  any claim or  liability  and of  complying  with any
process served upon it or any of its officers in connection with the exercise or
performance  of any of its powers or duties under this  Indenture and the Notes.
The Trustee shall notify the Company  promptly of any claim asserted against the
Trustee for which it may seek indemnity.  The Company shall defend the claim and
the Trustee shall provide reasonable cooperation at the Company's expense in the
defense.  The Trustee may have separate counsel of its selection and the Company
shall pay the reasonable fees and expenses of such counsel;  PROVIDED,  that the
Company  will not be  required  to pay such fees and  expenses if it assumes the
Trustee's  defense and there is no conflict of interest  between the Company and
the Trustee in connection  with such  defense.  The Company need not pay for any
settlement made without its written consent.

          To secure the Company's payment  obligations in this Section 7.07, the
Trustee shall have a lien prior to the Noteholders on 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,  premium,  if any, and interest on
particular Notes.

          If  the  Trustee  incurs  expenses  or  renders   services  after  the
occurrence  of an Event of  Default  specified  in clause  (h) or (i) of Section
6.01,  the expenses and the  compensation  for the services  will be intended to
constitute  expenses  of  administration  under  Title 11 of the  United  States
Bankruptcy  Code or any  applicable  federal  or  state  law for the  relief  of
debtors.

          The rights, privileges, protections and benefits given to the Trustee,
including,  without limitation,  its rights to be indemnified,  are extended to,
and shall be enforceable by, the Trustee in each of its capacities hereunder.


                                       59
<PAGE>

          The  provisions of this Section 7.07 shall survive the  resignation or
removal  of the  Trustee  and  the  defeasance  or  other  termination  of  this
Indenture.

          SECTION 7.08.  REPLACEMENT OF TRUSTEE. A resignation or removal of the
Trustee and appointment of a successor  Trustee shall become effective only upon
the  successor  Trustee's  acceptance  of its  appointment  as  provided in this
Section 7.08.

          The  Trustee  may resign at any time by so  notifying  the  Company in
writing  at least 30 days  prior to the date of the  proposed  resignation.  The
Holders of a majority in principal  amount of the  outstanding  Notes may remove
the Trustee by so  notifying  the Trustee in writing and may appoint a successor
Trustee with the consent of the Company.  The Company may at any time remove the
Trustee,  by  Company  Order  given at  least  30 days  prior to the date of the
proposed  removal;  PROVIDED  that, at such date, no Event of Default shall have
occurred and be continuing.

          If the Trustee  resigns or is removed,  or if a vacancy  exists in the
office of Trustee for any reason, 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  outstanding  Notes  may  appoint a
successor Trustee to replace the successor Trustee appointed by the Company.  If
the successor  Trustee does not deliver its written  acceptance  required by the
next succeeding paragraph of this Section 7.08 within 30 days after the retiring
Trustee resigns or is removed,  the retiring Trustee, the Company or the Holders
of a majority in principal  amount of the outstanding  Notes may petition at the
expense of the Company any court of competent  jurisdiction  for the appointment
of a successor Trustee.

          A  successor  Trustee  shall  deliver  a  written  acceptance  of  its
appointment to the retiring  Trustee and to the Company.  Immediately  after the
delivery of such  written  acceptance,  subject to the lien  provided in Section
7.07 of this  Indenture,  (i) the retiring  Trustee shall  transfer all property
held by it as Trustee to the successor Trustee,  (ii) the resignation or removal
of the retiring Trustee shall become  effective and (iii) the successor  Trustee
shall  have  all the  rights,  powers  and  duties  of the  Trustee  under  this
Indenture.  A  successor  Trustee  shall mail notice of its  succession  to each
Holder.

          If the  Trustee  is no  longer  eligible  under  Section  7.10 of this
Indenture,  any Holder who satisfies the  requirements of TIA Section 310(b) may
petition any court of competent  jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

          The Company  shall give notice of any  resignation  and any removal of
the Trustee and each  appointment  of a successor  Trustee to all Holders.  Each
notice shall  include the name of the  successor  Trustee and the address of its
Corporate Trust Office.

          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


                                       60
<PAGE>

corporation  or  national  banking  association,  the  resulting,  surviving  or
transferee  corporation or national banking  association without any further act
shall be the successor  Trustee with the same effect as if the successor Trustee
had been named as the Trustee herein.

          SECTION 7.10. ELIGIBILITY.  This Indenture shall always have a Trustee
who satisfies the  requirements  of TIA Sections  310(a)(1) and  310(a)(5).  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.

          SECTION 7.11. MONEY HELD IN TRUST. The Trustee shall not be liable for
interest  on any money  received  by it except as the Trustee may agree with the
Company in writing.  Money held in trust by the Trustee  need not be  segregated
from other funds except to the extent  required by law and except for money held
in trust under Article Eight of this Indenture.

          SECTION  7.12.  WITHHOLDING  TAXES.  The  Trustee,  as  agent  for the
Company,  shall exclude and withhold from each payment of principal and interest
and other amounts due hereunder or under the Notes any and all withholding taxes
applicable  thereto  as  required  by law.  The  Trustee  agrees  to act as such
withholding agent and, in connection  therewith,  whenever any present or future
taxes or similar charges are required to be withheld with respect to any amounts
payable in respect of the Notes,  to  withhold  such  amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the Holders of
the Notes, that it will file any necessary withholding tax returns or statements
when due, and that, as promptly as possible after the payment  thereof,  it will
deliver  to each  Holder  of a Note  appropriate  documentation  evidencing  the
payment  thereof,  together with such  additional  documentary  evidence as such
Holders may reasonably request from time to time.

                                  ARTICLE EIGHT
                             DISCHARGE OF INDENTURE

          SECTION  8.01.  TERMINATION  OF THE COMPANY'S  OBLIGATIONS.  Except as
otherwise  provided  in  this  Section  8.01,  the  Company  may  terminate  its
obligations under the Notes and this Indenture if:

          (i) all Notes  previously  authenticated  and  delivered  (other  than
     destroyed,  lost or stolen Notes that have been  replaced or Notes that are
     paid  pursuant to Section 4.01 hereof or Notes for whose  payment  money or
     securities have theretofore been held in trust and thereafter repaid to the
     Company,  as provided in Section 8.05  hereof)  have been  delivered to the
     Trustee for  cancellation  and the Company has paid all sums  payable by it
     hereunder; or


                                       61
<PAGE>

          (ii) (A) all of the Notes mature within one year or all of them are to
     be called for redemption within one year under arrangements satisfactory to
     the Trustee for giving the notice of redemption,  (B) the Company  deposits
     in trust with the Trustee during such one-year  period,  under the terms of
     an irrevocable  trust  agreement in form and substance  satisfactory to the
     Trustee,  as trust  funds  solely for the  benefit of the  Holders for that
     purpose,  money  or  European  Government  Obligations  sufficient  to  pay
     principal,  premium,  if,  any,  and  interest  on the Notes to maturity or
     redemption,  as the case may be,  and to pay all other  sums  payable by it
     hereunder,  (C) no Default or Event of  Default  with  respect to the Notes
     shall have occurred and be continuing on the date of such deposit, (D) such
     deposit  will not  result in a breach or  violation  of,  or  constitute  a
     default under, this Indenture or any other agreement or instrument to which
     the  Company  is a party or by which it is  bound,  (E) if at such time the
     Notes are listed on a national securities  exchange,  the Notes will not be
     delisted as a result of such  deposit,  defeasance or discharge and (F) the
     Company  has  delivered  to the  Trustee an  Officers'  Certificate  and an
     Opinion of Counsel,  in each case  stating  that all  conditions  precedent
     provided  for herein  relating to the  satisfaction  and  discharge of this
     Indenture have been complied with.

          With respect to the foregoing  clause (i), the  Company's  obligations
under Section 7.07 hereof shall  survive.  With respect to the foregoing  clause
(ii), the Company's  obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07,
2.08,  2.09, 2.14, 4.01, 4.02, 7.07, 7.08, 8.04, 8.05 and 8.06 of this Indenture
shall survive until the Notes are no longer  outstanding.  Thereafter,  only the
Company's  obligations in Sections 7.07,  8.05 and 8.06 of this Indenture  shall
survive.  After any such  irrevocable  deposit,  the Trustee upon request  shall
acknowledge in writing the discharge of the Company's  obligations,  as the case
may be,  under  the  Notes  and  this  Indenture,  except  for  those  surviving
obligations specified above.

          SECTION 8.02. DEFEASANCE AND DISCHARGE OF INDENTURE.  The Company will
be deemed to have paid and will be discharged  from any and all  obligations  in
respect of the Notes on the 123rd day after the deposit  referred to below,  and
the provisions of this Indenture will no longer be in effect with respect to the
Notes if:

          (A) the Company has deposited with the Trustee, in trust, money and/or
     European  Government  Obligations  that through the payment of interest and
     principal in respect  thereof in  accordance  with their terms will provide
     money in an amount sufficient to pay the principal of, premium, if any, and
     accrued  interest on the Notes on the Stated  Maturity of such  payments in
     accordance with the terms of this Indenture and the Notes;

          (B) the Company has delivered to the Trustee (i) either (1) an Opinion
     of Counsel to the effect that Holders will not  recognize  income,  gain or
     loss for federal income tax purposes as a result of the Company's  exercise
     of its option under this Section 8.02 and will be subject to federal income
     tax on the same  amount  and in the same  manner  and at the same  times as
     would have been the case if such deposit,  defeasance and discharge had not
     occurred, which Opinion of Counsel must be based upon (and accompanied by a
     copy of) a ruling of the Internal Revenue Service to the same effect unless


                                       62
<PAGE>

     there  has been a change in  applicable  federal  income  tax law after the
     Closing  Date  such that a ruling  is no  longer  required  or (2) a ruling
     directed to the Trustee  received from the Internal  Revenue Service to the
     same effect as the aforementioned Opinion of Counsel and (ii) an Opinion of
     Counsel to the effect that the  creation of the  defeasance  trust does not
     violate  the  Investment  Company  Act of 1940 and after the passage of 123
     days  following  the  deposit,  the trust  fund will not be  subject to the
     effect of Section 547 of the United States Bankruptcy Code or Section 15 of
     the New York Debtor and Creditor Law;

          (C)  immediately  after  giving  effect to such deposit on a PRO FORMA
     basis,  no Event of  Default,  or event  that after the giving of notice or
     lapse of time or both would become an Event of Default, shall have occurred
     and be  continuing  on the date of such deposit or during the period ending
     on the 123rd day after the date of such deposit, and such deposit shall not
     result in a breach or  violation  of, or  constitute a default  under,  any
     other  agreement  or  instrument  to  which  the  Company  or  any  of  its
     Subsidiaries is a party or by which the Company or any of its  Subsidiaries
     is bound; and

          (D) if at such  time the Notes are  listed  on a  national  securities
     exchange, the Company has delivered to the Trustee an Opinion of Counsel to
     the effect that the Notes will not be delisted as a result of such deposit,
     defeasance and discharge.

          Notwithstanding the foregoing,  prior to the end of the 123-day period
referred  to in clause  (B)(ii)  of this  Section  8.02,  none of the  Company's
obligations  under this Indenture shall be discharged.  Subsequent to the end of
such 123-day period with respect to this Section 8.02, the Company's obligations
in Sections 2.02,  2.03,  2.04,  2.05, 2.06, 2.07, 2.08, 2.09, 2.14, 4.01, 4.02,
4.17,  7.07,  7.08,  8.05 and 8.06 shall  survive  until the Notes are no longer
outstanding.  Thereafter,  only the Company's obligations in Sections 7.07, 8.05
and 8.06 shall survive.  If and when a ruling from the Internal  Revenue Service
or an Opinion of Counsel  referred to in clause  (B)(i) of this Section 8.02 may
be  provided  specifically  without  regard to, and not in  reliance  upon,  the
continuance of the Company's  obligations under Section 4.01, then the Company's
obligations  under such Section 4.01 shall cease upon delivery to the Trustee of
such  ruling or Opinion  of Counsel  and  compliance  with the other  conditions
precedent  provided for herein  relating to the defeasance  contemplated by this
Section 8.02.

          After the 123 day period referred to in clause (B)(ii) of this Section
8.02, the Trustee upon Company Order shall  acknowledge in writing the discharge
of the Company's obligations under the Notes and this Indenture except for those
surviving obligations in the immediately preceding paragraph.

          SECTION 8.03. DEFEASANCE OF CERTAIN OBLIGATIONS.  The Company may omit
to comply with any term,  provision or condition  set forth in clauses (iii) and
(iv) of Section 5.01 and  Sections  4.03  through  4.11 of this  Indenture,  and
clause (c) of  Section  6.01 with  respect to clauses  (iii) and (iv) of Section
5.01 of this  Indenture  and clause (d) of Section 6.01 with respect to Sections
4.01, 4.02 and 4.12 through 4.19 hereof, and clauses (e) and (f) of Section 6.01
hereof shall be deemed not to be Events of Default, upon:


                                       63
<PAGE>

          (a) the  deposit,  in trust,  with the  Trustee  (or  another  trustee
     satisfying  the  requirements  of  Section  7.10  hereof)  of money  and/or
     European  Government  Obligations that, through the payment of interest and
     principal in respect thereof in accordance  with their terms,  will provide
     money in an amount sufficient to pay the principal of, premium, if any, and
     accrued  interest on the Notes on the Stated  Maturity of such  payments in
     accordance with the terms of this Indenture and the Notes;

          (b) the satisfaction of the provisions described in clauses B(ii), (C)
     and (D) of Section 8.02 hereof;

          (c) delivery by the Company to the Trustee of an Opinion of Counsel to
     the effect that,  the Holders will not recognize  income,  gain or loss for
     federal  income tax purposes as a result of such deposit and defeasance and
     will be subject to  federal  income tax on the same  amount and in the same
     manner and at the same  times as would  have been the case if such  deposit
     and defeasance had not occurred; and

          (d) the  Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  and an  Opinion  of  Counsel,  in each case  stating  that all
     conditions  precedent  provided  for  herein  relating  to  the  defeasance
     contemplated by this Section 8.03 have been complied with.

          SECTION 8.04. APPLICATION OF TRUST MONEY. Subject to Section 8.06, the
Trustee  or  Paying  Agent  shall  hold in trust  money or  European  Government
Obligations  deposited  with it pursuant to Section  8.01,  8.02 or 8.03, as the
case may be, and shall  apply the  deposited  money and the money from  European
Government  Obligations  in accordance  with the Notes and this Indenture to the
payment of principal of,  premium,  if any, and interest on the Notes;  but such
money need not be segregated  from other funds except to the extent  required by
law.

          SECTION 8.05.  REPAYMENT TO COMPANY.  Subject to Sections 7.07,  8.01,
8.02 and 8.03,  the  Trustee  and the Paying  Agent  shall  promptly  pay to the
Company any excess  money,  as  determined  by a nationally  recognized  firm of
independent  public  accountants  expressed in a written  certification  thereof
delivered to the Trustee,  and held by them at any time and  thereupon  shall be
relieved  from all  liability  with  respect to such money.  The Trustee and the
Paying  Agent shall pay to the Company  upon  request any money held by them for
the payment of principal,  premium,  if any, or interest that remains  unclaimed
for two years;  PROVIDED  that the Trustee or such  Paying  Agent  before  being
required  to make any payment  may cause to be  published  at the expense of the
Company  once in a newspaper of general  circulation  in the City of New York or
mail to each  Holder  entitled  to such money at such  Holder's  address (as set
forth in the Note Register)  notice that such money remains  unclaimed  provided
that the Trustee or such Paying Agent before being  required to make any payment
may give notice in  accordance  with Section  11.02(b)  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  will be  repaid to the  Company.  After  payment  to the
Company, Holders entitled to such money must look to the


                                       64
<PAGE>

Company for payment as general  creditors  unless an applicable  law  designates
another  Person,  and all  liability  of the Trustee and such Paying  Agent with
respect to such money shall cease.

          SECTION  8.06.  REINSTATEMENT.  If the Trustee or the Paying  Agent is
unable to apply any money or European Government  Obligations in accordance with
Section  8.01,  8.02 or  8.03,  as the  case  may be,  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 Notes shall be revived and
reinstated as though no deposit had occurred  pursuant to Section 8.01,  8.02 or
8.03,  as the case may be,  until such time as the  Trustee  or Paying  Agent is
permitted  to  apply  all such  money  or  European  Government  Obligations  in
accordance  with Section 8.01,  8.02 or 8.03, as the case may be; PROVIDED that,
if the  Company  has made any  payment of  principal  of,  premium,  if any,  or
interest  on any Notes  because of the  reinstatement  of its  obligations,  the
Company  shall be  subrogated  to the  rights of the  Holders  of such  Notes to
receive such payment from the money or European  Government  Obligations held by
the Trustee or Paying Agent.

          SECTION 8.07.  DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT.  In the
event that the Company  exercises  its option to omit  compliance  with  certain
covenants and provisions of this Indenture with respect to the Notes pursuant to
Section  8.03 and  such  Notes  are  declared  due and  payable  because  of the
occurrence of an Event of Default that remains  applicable,  the amount of money
and/or  European  Government  Obligations  on deposit  with the Trustee  will be
sufficient  to pay  amounts  due on  such  Notes  at the  time of  their  Stated
Maturity.  If, in the event the Company  exercises its option to omit compliance
with certain  covenants  and  provisions of this  Indenture  with respect to the
Notes  pursuant  to Section  8.03 and such Notes are  declared  due and  payable
because of the  occurrence of an Event of Default that remains  applicable,  the
amount of money  and/or  European  Government  Obligations  on deposit  with the
Trustee  is  insufficient  to pay  amounts  due on the  Notes at the time of the
acceleration resulting from such Events of Default pursuant to Section 6.02, the
Company will remain liable for such payments.

                                  ARTICLE NINE
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 9.01. WITHOUT CONSENT OF HOLDERS. The Company, when authorized
by resolutions  of its Board of Directors (as evidenced by a Board  Resolution),
and the Trustee may amend or  supplement  this  Indenture  or the Notes  without
notice to, or the consent of, any Holder:

          (a) to cure any ambiguity,  defect or inconsistency in this Indenture;
     PROVIDED  that,  in the good faith opinion of the Board of Directors of the
     Company evidenced by a Board Resolution,  such amendments or supplements do
     not adversely affect the interests of the Holders in any material respect;


                                       65
<PAGE>

          (b) to comply with Article Five;

          (c) to comply with any  requirements  of the  Commission in connection
     with the qualification of this Indenture under the TIA;

          (d)  to  evidence  and  provide  for  the  acceptance  of  appointment
     hereunder by a successor Trustee; or

          (e) to make any change that, in the good faith opinion of the Board of
     Directors  of  the  Company  evidenced  by a  Board  Resolution,  does  not
     materially and adversely affect the rights of any Holder.

          SECTION  9.02.  WITH CONSENT OF HOLDERS.  Subject to Sections 6.07 and
without prior notice to the Holders,  the Company,  when authorized by its Board
of Directors  (as  evidenced by a Board  Resolution),  and the Trustee may amend
this  Indenture  and the Notes  with the  written  consent  of the  Holders of a
majority in aggregate  principal amount of the Notes then  outstanding,  and the
Holders  of  a  majority  in  aggregate  principal  amount  of  the  Notes  then
outstanding by written notice to the Trustee may waive compliance by the Company
with any provision of this Indenture or the Notes.

          Notwithstanding  the  provisions  of this  Section  9.02,  without the
consent of each Holder  affected  thereby,  an amendment or waiver,  including a
waiver pursuant to Section 6.04 hereof,  may not:

          (a) change the Stated Maturity of the principal of, or any installment
     of interest on, any Note;

          (b) reduce the  principal  amount of, or premium,  if any, or interest
     on, any Note;

          (c)  change the place or  currency  of  payment  of  principal  of, or
     premium, if any, or interest on, any Note;

          (d)  impair the right to  institute  suit for the  enforcement  of any
     payment on or after the Stated Maturity of any Note;

          (e) reduce the  above-stated  percentage  of  outstanding  Notes,  the
     consent of whose Holders is necessary to modify or amend this Indenture;

          (f) waive a default in the payment of principal of,  premium,  if any,
     or interest on the Notes; or

          (g) reduce the percentage or aggregate principal amount of outstanding
     Notes the consent of whose  Holders is necessary  for waiver of  compliance
     with  certain  provisions  of  this  Indenture  or for  waiver  of  certain
     defaults.


                                       66
<PAGE>

          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 Trustee  shall mail to the Holders  affected  thereby a
notice briefly describing the amendment,  supplement or waiver. The Company will
mail supplemental indentures to Holders upon request. 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 or waiver.

          SECTION 9.03. REVOCATION AND EFFECT OF CONSENT.  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 a Note or  portion  of a Note that
evidences the same debt as the Note of the consenting  Holder,  even if notation
of the consent is not made on any Note.  However,  any such Holder or subsequent
Holder  may revoke  the  consent  as to its Note or  portion  of its Note.  Such
revocation  shall be  effective  only if the  Trustee  receives  the  notice  of
revocation  before  the  date  the  amendment,   supplement  or  waiver  becomes
effective. An amendment,  supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite  percentage
in principal amount of the outstanding Notes.

          The Company may, but shall not be obligated  to, fix a record date for
the purpose of  determining  the Holders  entitled to consent to any  amendment,
supplement or waiver. If a record date is fixed, then,  notwithstanding the last
two sentences of the  immediately  preceding  paragraph,  those Persons who were
Holders 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  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  Holder  unless it is of the type  described  in any of  clauses  (i)
through  (vii) of Section  9.02.  In case of an  amendment or waiver of the type
described in clauses (i) through (vii) of Section 9.02,  the amendment or waiver
shall bind each Holder who has consented to it and every subsequent  Holder of a
Note that evidences the same indebtedness as the Note of the consenting Holder.

          SECTION  9.04.  NOTATION  ON OR EXCHANGE  OF NOTES.  If an  amendment,
supplement  or waiver  changes the terms of a Note,  the Trustee may require the
Holder to  deliver  it to the  Trustee.  The  Trustee  may place an  appropriate
notation on the Note about the changed terms and return it to the Holder and the
Trustee may place an appropriate notation on any Note thereafter  authenticated.
Alternatively,  if the  Company or the  Trustee so  determines,  the  Company in
exchange for the Note shall issue and the Trustee shall  authenticate a new Note
that reflects the changed terms.


                                       67
<PAGE>

          SECTION 9.05.  TRUSTEE TO SIGN  AMENDMENTS,  ETC. The Trustee shall be
entitled to receive,  and shall be fully  protected in relying upon, in addition
to the documents  required by Section 11.03,  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.  Subject to the
preceding sentence, the Trustee shall sign such amendment,  supplement or waiver
if the same does not  adversely  affect the rights of the  Trustee.  The Trustee
may, but shall not be obligated to,  execute any such  amendment,  supplement or
waiver that affects the  Trustee's own rights,  duties or immunities  under this
Indenture or otherwise.

          SECTION 9.06.  CONFORMITY WITH TRUST INDENTURE ACT. Every supplemental
indenture   executed  pursuant  to  this  Article  Nine  shall  conform  to  the
requirements of the TIA as then in effect.

                                   ARTICLE TEN
                                   [RESERVED]

          SECTION 11.01. TRUST INDENTURE ACT OF 1939. Prior to the effectiveness
of the Registration Statement,  this Indenture shall incorporate and be governed
by the  provisions  of the TIA that are  required or deemed to be part of and to
govern  indentures  qualified  under  the TIA.  After the  effectiveness  of the
Registration Statement, this Indenture shall be subject to the provisions of the
TIA that are required or deemed to be a part of this Indenture and shall, to the
extent applicable, be governed by such provisions.

          SECTION  11.02.  NOTICES.  (a) Any  notice or  communication  shall be
sufficiently  given if in  writing  and  delivered  in person or mailed by first

                  Attention:  Corporate Trust Administration

          The Company,  the Trustee,  or the  Depository by notice to the others
may  designate  additional  or different  addresses  for  subsequent  notices or
communications.

          All  notices  and  communications  (other  than those sent to Holders)
shall be deemed  to have been duly  given:  at the time  delivered  by hand,  if
personally  delivered;  five  Business  Days after being  deposited in the mail,
postage prepaid, if mailed; when receipt  acknowledged,  if telecopied;  and the
next Business Day after timely delivery to the courier, if sent by overnight air
courier guaranteeing next day delivery.

          (b) Any notice or  communication  mailed to a Holder shall be mailed
to him at his address as it appears on the Note Register by first class mail and
shall be  sufficiently  given to him if so mailed  within  the time  prescribed.
Copies of any such  communication  or notice to a Holder shall also be mailed to
the Trustee and each Agent at the same time.

          Failure to mail a notice or communication to a Holder or any defect in
it shall not affect its sufficiency with respect to other Holders.  Except for a
notice to the Trustee,  which is deemed given only when received,  and except as
otherwise provided in this Indenture,  if a notice or communication is mailed in
the manner provided in this Section 11.02, it is duly given,  whether or not the
addressee receives it.

          (c) Where  this  Indenture  provides for notice in any manner,  such
notice may be waived in writing by the Person  entitled to receive  such notice,
either  before or after the event,  and such waiver shall be the  equivalent  of
such notice.  Waivers of notice by Holders shall be filed with the Trustee,  but
such filing  shall not be a condition  precedent  to the  validity of any action
taken in reliance upon such waiver.

          In case by reason of the  suspension  of  regular  mail  service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such  notification  as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

          SECTION  11.03.  CERTIFICATE  AND OPINION AS TO CONDITIONS  PRECEDENT.

Trustee may make reasonable rules for action by or at a meeting of Holders.  The

          SECTION 11.06.  PAYMENT DATE OTHER THAN A BUSINESS DAY. If an Interest
Payment  Date,  Payment  Date,  Stated  Maturity or date of maturity of any Note
shall not be a Business Day, then payment of principal of,  premium,  if any, or
interest on such Note,  as the case may be,  need not be made on such date,  but
may be made on the next  succeeding  Business Day with the same force and effect
as if made on the  Interest  Payment  Date or  Payment  Date,  or at the  Stated
Maturity  or date of  maturity of such Note;  PROVIDED  that no  interest  shall
accrue for the period from and after such Interest  Payment Date,  Payment Date,

          SECTION  11.13.  TABLE  OF  CONTENTS,  HEADINGS,  ETC.  The  Table  of
Contents,  Cross-Reference  Table and  headings of the  Articles and Sections of
this Indenture have been inserted for  convenience of reference only, are not to
be  considered  a part hereof and shall in no way modify or restrict  any of the
terms and provisions hereof.

          SECTION  11.14.  METHOD OF PAYMENT.  (a) Euro is the sole  currency of
account and payment for all sums payable by the Company  under or in  connection
with the Notes, including damages, except as otherwise set forth in this Section
11.14.

          (b) Investors who hold beneficial  interests in the Notes,  directly
or  indirectly,  through DTC ("DTC  NOTEHOLDERS")  will be paid in U.S.  dollars
converted  from such payments in Euro by the Paying Agent unless the  registered
holder, on behalf of any such owner of beneficial  interests,  elects to receive
payments in Euro.

          Upon receipt of notice of such election and wire transfer instructions
on or prior to the fourth New York Business Day (as defined in clause (c) below)
after the record date for any  payment of interest  and on or prior to the sixth
New York Business Day prior to the payment of  principal,  the Paying Agent will
make such payments in Euro to the Euro accounts of the relevant Holders.

          The Paying Agent shall convert the  remainder of the aggregate  amount
of such payments into U.S.  dollars,  based on the Paying Agent's bid quotation,
at or prior to 11:00 a.m.,  New York Time,  on the second New York  Business Day
preceding the date of such payment,  for the purchase of U.S. dollars with Euro,
for  settlement  on the  date of such  payment.  If such  bid  quotation  is not
available,  all such payments will be made in Euro, outside DTC to Euro accounts
maintained by such DTC Noteholders.

          (c) All  costs  of  conversion,  if any,  will be  borne by such DTC
Noteholders,  by  deduction  from such  payments.  All costs of  payment by wire
transfer referred to in paragraph (b) above will be borne by registered  holders
receiving  such payments by deduction  from such  payments.  For purposes of the
foregoing,  "NEW YORK BUSINESS DAY" means a day all banking institutions are not
authorized  or obligated  by law or executive  order to be closed in the City of
New York.

          SECTION 11.15. JUDGMENT CURRENCY. Subject to Section 7.07, the Company
hereby agrees to indemnify the Trustee and any  predecessor  trustee  (acting on
behalf of the Holders or otherwise)  against any loss incurred by such person as
a result of any  judgment or order  being made or given  against the Company for
any Euro  amount due under this  Indenture.  The  Company  hereby also agrees to
indemnify such Trustee and any predecessor  trustee against any loss incurred by
such person if such judgment or order is being  expressed and paid in a currency
other  than Euro (the  "JUDGMENT  CURRENCY"),  as a result of any  variation  as
between (i) the rate of exchange at


                                       72
<PAGE>

which the Euro 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 on which such party on the date of  payment  of such  judgment  or order is
able to purchase Euro 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.  The term "spot rate of  exchange"
shall include any premiums or costs of exchange  payable in connection  with the
purchase of, or conversion into the Euro.

                        12 3/4% Senior Euro Note due 2008



1.    PRINCIPAL AND INTEREST.

          The Company will pay the principal of this Note on April 15, 2008.

          The Company  promises to pay interest on the principal  amount of this
Note on each Interest  Payment  Date, as set forth below,  at the rate per annum
shown above.

          Interest  will be  payable  semiannually  in cash (to the  holders  of
record  of the  Notes at the  close of  business  on the  April 1 or  October  1
immediately  preceding the Interest Payment Date) on each Interest Payment Date,
commencing October 15, 2000. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

          If an  exchange  offer  registered  under  the  Securities  Act is not
consummated,  and a shelf  registration  statement under the Securities Act with
respect to resales of the Notes is not declared effective by the Commission,  on
or before the date that is 180 days after the Closing  Date in  accordance  with
the terms of the Registration  Rights Agreement,  dated April 14, 2000,  between
the Company and Morgan Stanley & Co.  International  Limited, as the manager for
itself and the several  placement  agents  named on Schedule I to the  Placement
Agreement,  dated  April 14,  2000,  annual  interest  (in  addition to interest
otherwise  due on the Notes) will accrue,  at an annual rate of .5% per annum of
the principal amount,  payable in cash semiannually,  in arrears on April 15 and
October 15 of each year, commencing October 15, 2000 until the consummation of a
registered exchange offer or the effectiveness of a shelf-registration statement
with respect to resale of this Note.  The Holder of this Note is entitled to the
benefits of such Registration Rights Agreement.

          The Company shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at
a rate per annum that is 12 3/4% per annum.

2.    METHOD OF PAYMENT.

          The Company will pay principal as provided above and interest  (except
defaulted  interest) on the principal  amount of the Notes as provided  above on
each April 15 and October 15 to the Persons who are Holders (as reflected in the
Note  Register  at the  close  of  business  on  such  April  1 and  October  1,
immediately preceding the Interest Payment Date), in each case, even if the Note
is cancelled on  registration of transfer or registration of exchange after such
record  date;  PROVIDED  that,  with  respect to the payment of  principal,  the
Company will not make payment to the Holder unless this Note is surrendered to a
Paying Agent.


                                       A-5
<PAGE>

          The  Company  will pay  principal,  premium,  if any,  and as provided
above,  interest in Euros.  However, the Company may pay principal,  premium, if
any, and interest by its check payable in such currency. It may mail an interest
check to a Holder's registered address (as reflected in the Note Register). If a
payment date is a date other than a Business Day at a place of payment,  payment
may be made at that place on the next  succeeding day that is a Business Day and
no interest shall accrue for the intervening period.

3.    PAYING AGENT AND REGISTRAR.

          Initially,  the Trustee will act as Paying Agent and Registrar and the
Trustee  (through its London Branch) will act as Euro Paying Agent.  The Company
will  maintain a paying  agent in Frankfurt in the event the Notes are listed on
the Frankfurt  over-the-counter  market. The Company may change any Paying Agent
or Registrar without notice. The Company, any Subsidiary or any Affiliate of any
of them may act as Paying Agent, Registrar or co-Registrar.

4.    INDENTURE; ISSUANCE OF ADDITIONAL NOTES.

          This Note is one of a duly  authorized  issue of Notes of the  Company
designated  its 12 3/4% Senior Notes due 2008,  issued and to be issued under an
Indenture, dated as of April 20, 2000 (the "Indenture"), between the Company and
the Trustee.  Capitalized terms used herein are used as defined in the Indenture
unless otherwise  indicated.  The terms of the Notes include those stated in the
Indenture  and  those  made  part of the  Indenture  by  reference  to the Trust
Indenture Act. The Notes are subject to all such terms, and Holders are referred
to the Indenture and the Trust  Indenture Act for a statement of all such terms.
To the extent  permitted by  applicable  law, in the event of any  inconsistency
between the terms of this Note and the terms of the Indenture,  the terms of the
Indenture shall control.

5.    REPURCHASE UPON CHANGE IN CONTROL.

          Upon the  occurrence of any Change of Control,  each Holder shall have
the right to require the repurchase of its Notes by the Company in cash pursuant
to the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid  interest,  if any, to the date
of purchase (the "Change of Control Payment").

          A notice of such Change of Control will be mailed within 30 days after
any Change of Control occurs to each Holder at his last address as it appears in
the Note  Register.  Notes in original  denominations  larger than Euro 1,000 of
principal  amount may be sold to the  Company in part.  On and after the date of
the Change of Control Payment, interest ceases to accrue on Notes or portions of
Notes  surrendered for purchase by the Company,  unless the Company  defaults in
the payment of the Change of Control Payment.

6.    REGISTRATION RIGHTS

          Pursuant to the  Registration  Rights  Agreement,  the Company will be
obligated,  within 180 days  after the issue date of this Note,  to use its best
efforts to  consummate  an exchange  offer  pursuant to which the Holder of this


                                       A-6
<PAGE>

Note shall have the right to exchange this Note for the Company's Exchange Notes
(as defined in the  Registration  Rights  Agreement)  which have been registered
under the Securities Act, in like principal amount and having terms identical in
all material  respects to the initial  Notes.  The Holders of the initial  Notes
shall be entitled to receive certain  additional  interest payments in the event
such exchange offer is not  consummated and upon certain other  conditions,  all
pursuant and in accordance with the terms of the Registration Rights Agreement.

7.    DENOMINATIONS; TRANSFER; EXCHANGE.

          The Notes are in registered form without coupons in  denominations  of
Euro 1,000 of  principal  amount  and any  integral  multiples  of Euro 1,000 in
excess  thereof.  A Holder may  register  the  transfer  or exchange of Notes in
accordance with the Indenture.  The Registrar may require a Holder,  among other
things, to furnish  appropriate  endorsements and transfer  documents and to pay
any taxes and fees required by law or permitted by the Indenture.

8.    PERSONS DEEMED OWNERS.

          A Holder shall be treated as the owner of a Note for all purposes.

9.    UNCLAIMED MONEY.

          If money for the payment of  principal,  premium,  if any, or interest
remains  unclaimed for two years,  the Trustee and the Paying Agent will pay the
money back to the Company at its request.  After that,  Holders  entitled to the
money must look to the Company for  payment,  unless an  abandoned  property law
designates  another  Person,  and all  liability  of the Trustee and such Paying
Agent with respect to such money shall cease.

10.   DISCHARGE PRIOR TO REDEMPTION OR MATURITY.

          If the  Company  deposits  with  the  Trustee  money  and/or  European
Government  Obligations  sufficient  to pay the then  outstanding  principal of,
premium,  if any,  and  accrued  interest  on the  Notes  (a) to  redemption  or
maturity,  the Company  will be  discharged  from the  Indenture  and the Notes,
except in certain  circumstances for certain sections thereof, and (b) to Stated
Maturity, the Company will be discharged from certain covenants set forth in the
Indenture.

11.   AMENDMENT; SUPPLEMENT; WAIVER.

          Subject  to  certain  exceptions,  the  Indenture  or the Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in principal amount of the Notes then  outstanding,  and any existing default or
compliance  with any  provision may be waived with the consent of the Holders of
at least a majority in principal amount of the Notes then  outstanding.  Without
notice  to or the  consent  of any  Holder,  the  parties  thereto  may amend or
supplement  the  Indenture  or the  Notes  to,  among  other  things,  cure  any
ambiguity,  defect or inconsistency and make any change that does not materially
and adversely affect the rights of any Holder.

the Company (and to the Trustee if such notice is given by the Holders) may, and
the Trustee at the request of such Holders shall,  declare the principal  amount
of, premium, if any, and accrued interest on the Notes to be immediately due and
payable.

          If a  bankruptcy  or  insolvency  default  with respect to the Company
occurs  and is  continuing,  the Notes  automatically  become  due and  payable.
Holders  may not enforce the  Indenture  or the Notes  except as provided in the
Indenture.  The  Trustee  may  require  indemnity  satisfactory  to it before it
enforces the Indenture or the Notes. Subject to certain limitations,  Holders of

the Trustee in its exercise of any trust or power.

Affiliates as if it were not the Trustee.

          No incorporator or any past,  present or future partner,  stockholder,
other equity holder, officer, director,  employee or controlling person as such,

obligations  of the Company  under the Notes or the  Indenture  or for any claim
based on, in respect of or by reason of,  such  obligations  or their  creation.

Note on each Interest  Payment  Date, as set forth below,  at the rate per annum
shown above.

          Interest  will be  payable  semiannually  in cash (to the  holders  of
record  of the  Notes at the  close of  business  on the  April 1 or  October  1
immediately  preceding the Interest Payment Date) on each Interest Payment Date,
commencing October 15, 2000. Interest will be computed on the basis of a 360-day

Agreement,  dated  April 14,  2000,  annual  interest  (in  addition to interest
otherwise due on the Notes) will accrue,  at an annual rate of 0.5% per annum of
the principal amount,  payable in cash semiannually,  in arrears on April 15 and
October 15 of each year, commencing October 15, 2000 until the consummation of a
registered exchange offer or the effectiveness of a shelf-registration statement
with respect to resale of this Note.  The Holder of this Note is entitled to the
benefits of such Registration Rights Agreement.

          The Company shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at

each April 15 and October 15 to the Persons who are Holders (as reflected in the
Note  Register  at the  close  of  business  on  such  April  1 and  October  1,
immediately preceding the Interest Payment Date), in each case, even if the Note

          The  Company  will pay  principal,  premium,  if any,  and as provided
above,  interest in Euros.  However, the Company may pay principal,  premium, if
any, and interest by its check payable in such currency. It may mail an interest
check to a Holder's registered address (as reflected in the Note Register). If a
payment date is a date other than a Business Day at a place of payment,  payment
may be made at that place on the next  succeeding day that is a Business Day and
no interest shall accrue for the intervening period.

3.    PAYING AGENT AND REGISTRAR.

          Initially,  the Trustee will act as Paying Agent and Registrar and the
Trustee  (through its London Branch) will act as Euro Paying Agent.  The Company
will  maintain a paying  agent in Frankfurt in the event the Notes are listed on
the Frankfurt  over-the-counter  market. The Company may change any Paying Agent
or Registrar without notice. The Company, any Subsidiary or any Affiliate of any
of them may act as Paying Agent, Registrar or co-Registrar.

4.    INDENTURE; ISSUANCE OF ADDITIONAL NOTES.

          This Note is one of a duly  authorized  issue of Notes of the  Company
designated  its 12 3/4% Senior Notes due 2008,  issued and to be issued under an
Indenture, dated as of April 20, 2000 (the "Indenture"), between the Company and
the  Trustee.  Capitalized  terms  herein are used as  defined in the  Indenture
unless otherwise  indicated.  The terms of the Notes include those stated in the
Indenture  and  those  made  part of the  Indenture  by  reference  to the Trust
Indenture Act. The Notes are subject to all such terms, and Holders are referred
to the Indenture and the Trust  Indenture Act for a statement of all such terms.
To the extent  permitted by  applicable  law, in the event of any  inconsistency
between the terms of this Note and the terms of the Indenture,  the terms of the
Indenture shall control.

5.    REPURCHASE UPON CHANGE IN CONTROL.

          Upon the  occurrence of any Change of Control,  each Holder shall have
the right to require the repurchase of its Notes by the Company in cash pursuant
to the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid  interest,  if any, to the date
of purchase (the "Change of Control Payment").

          A notice of such Change of Control will be mailed within 30 days after
any Change of Control occurs to each Holder at his last address as it appears in
the Note  Register.  Notes in original  denominations  larger than Euro 1,000 of
principal  amount may be sold to the  Company in part.  On and after the date of
the Change of Control Payment, interest ceases to accrue on Notes or portions of
Notes  surrendered for purchase by the Company,  unless the Company  defaults in
the payment of the Change of Control Payment.

6.    REGISTRATION RIGHTS

          Pursuant to the  Registration  Rights  Agreement,  the Company will be
obligated,  within 180 days  after the issue date of this Note,  to use its best
efforts to  consummate  an exchange  offer  pursuant to which the Holder of this
Note shall have the right to exchange this Note for the Company's Exchange Notes

<PAGE>

under the Securities Act, in like principal amount and having terms identical in
all material  respects to the initial  Notes.  The Holders of the initial  Notes
shall be entitled to receive certain  additional  interest payments in the event
such exchange offer is not  consummated and upon certain other  conditions,  all
pursuant and in accordance with the terms of the Registration Rights Agreement.

7.    DENOMINATIONS; TRANSFER; EXCHANGE.

          The Notes are in registered form without coupons in  denominations  of
Euro 1,000 of  principal  amount  and any  integral  multiples  of Euro 1,000 in
excess  thereof.  A Holder may  register  the  transfer  or exchange of Notes in
accordance with the Indenture.  The Registrar may require a Holder,  among other
things, to furnish  appropriate  endorsements and transfer  documents and to pay
any taxes and fees required by law or permitted by the Indenture.

8.    PERSONS DEEMED OWNERS.

          A Holder shall be treated as the owner of a Note for all purposes.

9.    UNCLAIMED MONEY.

          If money for the payment of  principal,  premium,  if any, or interest
remains  unclaimed for two years,  the Trustee and the Paying Agent will pay the
money back to the Company at its request.  After that,  Holders  entitled to the
money must look to the Company for  payment,  unless an  abandoned  property law
designates  another  Person,  and all  liability  of the Trustee and such Paying
Agent with respect to such money shall cease.

10.   DISCHARGE PRIOR TO REDEMPTION OR MATURITY.

          If the  Company  deposits  with  the  Trustee  money  and/or  European
Government  Obligations  sufficient  to pay the then  outstanding  principal of,
premium,  if any,  and  accrued  interest  on the  Notes  (a) to  redemption  or
maturity,  the Company  will be  discharged  from the  Indenture  and the Notes,
except in certain  circumstances for certain sections thereof, and (b) to Stated
Maturity, the Company will be discharged from certain covenants set forth in the
Indenture.

11.   AMENDMENT; SUPPLEMENT; WAIVER.

          Subject  to  certain  exceptions,  the  Indenture  or the Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in principal amount of the Notes then  outstanding,  and any existing default or
compliance  with any  provision may be waived with the consent of the Holders of
at least a majority in principal amount of the Notes then  outstanding.  Without
notice  to or the  consent  of any  Holder,  the  parties  thereto  may amend or
supplement  the  Indenture  or the  Notes  to,  among  other  things,  cure  any
ambiguity,  defect or inconsistency and make any change that does not materially
and adversely affect the rights of any Holder.

obligations  of the Company  under the Notes or the  Indenture  or for any claim
based on, in respect of or by reason of,  such  obligations  or their  creation.

                             [REVERSE SIDE OF NOTE]

                                  VIATEL, INC.

                        12 3/4% Senior Euro Note due 2008



1.    PRINCIPAL AND INTEREST.

          The Company will pay the principal of this Note on April 15, 2008.

          The Company  promises to pay interest on the principal  amount of this
Note on each Interest  Payment  Date, as set forth below,  at the rate per annum
shown above.

          Interest  will be  payable  semiannually  in cash (to the  holders  of
record  of the  Notes at the  close of  business  on the  April 1 or  October  1
immediately  preceding the Interest Payment Date) on each Interest Payment Date,
commencing October 15, 2000. Interest will be computed on the basis of a 360 day
year of twelve 30 day months.

          If an  exchange  offer  registered  under  the  Securities  Act is not
consummated,  and a shelf  registration  statement under the Securities Act with
respect to resales of the Notes is not declared effective by the Commission,  on
or before the date that is 180 days after the Closing  Date in  accordance  with
the terms of the Registration  Rights Agreement dated April 14, 2000 between the
Company  and Morgan  Stanley & Co.  International  Limited,  as the  manager for
itself and the several  placement  agents  named on Schedule I to the  Placement
Agreement  dated  April 14,  2000,  annual  interest  (in  addition  to interest
otherwise due on the Notes) will accrue,  at an annual rate of 0.5% per annum of
the principal amount,  payable in cash semiannually,  in arrears on April 15 and
October 15 of each year, commencing October 15, 2000 until the consummation of a
registered exchange offer or the effectiveness of a shelf-registration statement
with respect to resale of this Note.  The Holder of this Note is entitled to the
benefits of such Registration Rights Agreement.

          The Company shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at
a rate per annum that is 12 3/4% per annum.

2.    METHOD OF PAYMENT.

          The Company will pay principal as provided above and interest  (except
defaulted  interest) on the principal  amount of the Notes as provided  above on
each April 15 and October 15 to the Persons who are Holders (as reflected in the
Note  Register  at the  close  of  business  on  such  April  1 and  October  1,
immediately preceding the Interest Payment Date), in each case, even if the Note
is cancelled on  registration of transfer or registration of exchange after such
record  date;  PROVIDED  that,  with  respect to the payment of  principal,  the
Company will not make payment to the Holder unless this Note is surrendered to a
Paying Agent.


                                      C-5
<PAGE>

          The  Company  will pay  principal,  premium,  if any,  and as provided
above,  interest in Euros.  However, the Company may pay principal,  premium, if
any, and interest by its check payable in such currency. It may mail an interest
check to a Holder's registered address (as reflected in the Note Register). If a
payment date is a date other than a Business Day at a place of payment,  payment
may be made at that place on the next  succeeding day that is a Business Day and
no interest shall accrue for the intervening period.

3.    PAYING AGENT AND REGISTRAR.

          Initially, the Trustee will act as U.S. Paying Agent and Registrar and
the Trustee  (through  its London  Branch)  will act as Euro Paying  Agent.  The
Company  will  maintain a paying  agent in  Frankfurt in the event the Notes are
listed on the  Frankfurt  over-the-counter  market.  The  Company may change any
Paying Agent or Registrar  without  notice.  The Company,  any Subsidiary or any
Affiliate of any of them may act as Paying Agent, Registrar or co-Registrar.

4.    INDENTURE; ISSUANCE OF ADDITIONAL NOTES.

          This Note is one of a duly  authorized  issue of Notes of the  Company
designated its 12 3/4% Senior Euro Notes due 2008, issued and to be issued under
an Indenture dated as of April 20, 2000 (the  "Indenture"),  between the Company
and the Trustee.  Capitalized  terms herein are used as defined in the Indenture
unless otherwise  indicated.  The terms of the Notes include those stated in the
Indenture  and  those  made  part of the  Indenture  by  reference  to the Trust
Indenture Act. The Notes are subject to all such terms, and Holders are referred
to the Indenture and the Trust  Indenture Act for a statement of all such terms.
To the extent  permitted by  applicable  law, in the event of any  inconsistency
between the terms of this Note and the terms of the Indenture,  the terms of the
Indenture shall control.

5.    REPURCHASE UPON CHANGE IN CONTROL.

          Upon the  occurrence of any Change of Control,  each Holder shall have
the right to require the repurchase of its Notes by the Company in cash pursuant
to the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid  interest,  if any, to the date
of purchase (the "Change of Control Payment").

          A notice of such Change of Control will be mailed within 30 days after
any Change of Control occurs to each Holder at his last address as it appears in
the Note  Register.  Notes in original  denominations  larger than Euro 1,000 of
principal  amount may be sold to the  Company in part.  On and after the date of
the Change of Control Payment, interest ceases to accrue on Notes or portions of
Notes  surrendered for purchase by the Company,  unless the Company  defaults in
the payment of the Change of Control Payment.

6.    REGISTRATION RIGHTS

          Pursuant to the  Registration  Rights  Agreement,  the Company will be
obligated,  within 180 days  after the issue date of this Note,  to use its best
efforts to  consummate  an exchange  offer  pursuant to which the Holder of this


                                      C-6
<PAGE>

Note shall have the right to exchange this Note for the Company's Exchange Notes
(as defined in the  Registration  Rights  Agreement)  which have been registered
under the Securities Act, in like principal amount and having terms identical in
all material  respects to the initial  Notes.  The Holders of the initial  Notes
shall be entitled to receive certain  additional  interest payments in the event
such exchange offer is not  consummated and upon certain other  conditions,  all
pursuant and in accordance with the terms of the Registration Rights Agreement.

7.    DENOMINATIONS; TRANSFER; EXCHANGE.

          The Notes are in registered form without coupons in  denominations  of
Euro 1,000 of  principal  amount  and any  integral  multiples  of Euro 1,000 in
excess  thereof.  A Holder may  register  the  transfer  or exchange of Notes in
accordance with the Indenture.  The Registrar may require a Holder,  among other
things, to furnish  appropriate  endorsements and transfer  documents and to pay
any taxes and fees required by law or permitted by the Indenture.

8.    PERSONS DEEMED OWNERS.

          A Holder shall be treated as the owner of a Note for all purposes.

9.    UNCLAIMED MONEY.

          If money for the payment of  principal,  premium,  if any, or interest
remains  unclaimed for two years,  the Trustee and the Paying Agent will pay the
money back to the Company at its request.  After that,  Holders  entitled to the
money must look to the Company for  payment,  unless an  abandoned  property law
designates  another  Person,  and all  liability  of the Trustee and such Paying
Agent with respect to such money shall cease.

10.   DISCHARGE PRIOR TO REDEMPTION OR MATURITY.

          If the  Company  deposits  with  the  Trustee  money  and/or  European
Government  Obligations  sufficient  to pay the then  outstanding  principal of,
premium,  if any,  and  accrued  interest  on the  Notes  (a) to  redemption  or
maturity,  the Company  will be  discharged  from the  Indenture  and the Notes,
except in certain  circumstances for certain sections thereof, and (b) to Stated
Maturity, the Company will be discharged from certain covenants set forth in the
Indenture.

11.   AMENDMENT; SUPPLEMENT; WAIVER.

          Subject  to  certain  exceptions,  the  Indenture  or the Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in principal amount of the Notes then  outstanding,  and any existing default or
compliance  with any  provision may be waived with the consent of the Holders of
at least a majority in principal amount of the Notes then  outstanding.  Without
notice  to or the  consent  of any  Holder,  the  parties  thereto  may amend or
supplement  the  Indenture  or the  Notes  to,  among  other  things,  cure  any
ambiguity,  defect or inconsistency and make any change that does not materially
and adversely affect the rights of any Holder.

          Re: Viatel, Inc. (the "Company")
              12 3/4% Senior Euro Notes
              DUE 2008 (THE "NOTES")

Dear Sirs:

          In connection with our proposed purchase of Euro ___________ aggregate
principal amount of the Notes, we confirm that:

          1. We understand that any subsequent  transfer of the Notes is subject
     to certain  restrictions and conditions set forth in the Indenture dated as
     of  April  20,  2000  relating  to the  Notes  (the  "Indenture")  and  the
     undersigned  agrees to be bound by, and not to resell,  pledge or otherwise
     transfer  the Notes  except  in  compliance  with,  such  restrictions  and
     conditions  and the  Securities  Act of 1933,  as amended (the  "Securities
     Act").

          2. We  understand  that the offer and sale of the Notes  have not been
     registered  under the Securities Act, and that the Notes may not be offered
     or sold except as permitted in the following sentence. We agree, on our own
     behalf and on behalf of any accounts for which we are acting as hereinafter
     stated,  that if we should  sell any  Notes,  we will do so only (A) to the
     Company or any subsidiary  thereof,  (B) in accordance with Rule 144A under
     the  Securities  Act  to a  "qualified  institutional  buyer"  (as  defined
     therein), (C) to an institutional  "accredited investor" (as defined below)
     that, prior to such transfer,  furnishes (or has furnished on its behalf by
     a  U.S.   broker-dealer)  to  you  and  to  the  Company  a  signed  letter
     substantially in the form of this letter,  (D) outside the United States in
     accordance  with Rule 904 of  Regulation  S under the  Securities  Act, (E)
     pursuant to the  provisions  of Rule 144 under the  Securities  Act, or (F)
     pursuant to an effective  registration  statement under the Securities Act,
     and we further agree to provide to any person  purchasing  any of the Notes
     from us a notice  advising  such  purchaser  that  resales of the Notes are
     restricted as stated herein.

          3. We understand that, on any proposed resale of any Notes, we will be
     required  to  furnish to you and the  Company  such  certifications,  legal


                                      F-1
<PAGE>

     opinions  and  other  information  as you and the  Company  may  reasonably
     require to confirm  that the  proposed  sale  complies  with the  foregoing
     restrictions.  We further  understand  that the Notes  purchased by us will
     bear a legend to the foregoing effect.

          4. We are an institutional  "accredited  investor" (as defined in Rule
     501(a)(1),  (2), (3) or (7) of Regulation D under the  Securities  Act) and
     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.

          5. We are acquiring  the Notes  purchased by us for our own account or
     for one or more  accounts  (each of which is an  institutional  "accredited
     investor") as to each of which we exercise sole investment discretion.

          You and the  Company  are  entitled  to rely upon this  letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any  administrative  or legal  proceedings  or  official  inquiry  with

Depositary  or by a nominee  of the  Depositary  to the  Depositary  or  another
nominee to a successor Depositary or a nominee of such successor Depositary.

registered  in the name of Cede & Co.,  as the  nominee of the  Depositary,  and
deposited with the Trustee as custodian for Cede & Co.

               Definitive Convertible Debentures issued in exchange for all or a
part of a Global  Debenture  pursuant to this Section 2.4(d) shall be registered
in such names and in such authorized  denominations as the Depositary,  pursuant
to instructions  from its direct or indirect  participants  or otherwise,  shall
instruct the Trustee.  Upon  execution  and  authentication,  the Trustee  shall
deliver such definitive Convertible Debentures to the person in whose names such
definitive Convertible Debentures are so registered.

               At such time as all  interests  in a Global  Debenture  have been
redeemed, converted,  exchanged,  repurchased or canceled, such Global Debenture
shall be, upon  receipt  thereof,  canceled by the  Trustee in  accordance  with
standing  procedures and  instructions of the  Depositary.  At any time prior to
such  cancellation,  if any  interest in a Global  Debenture  is  exchanged  for
definitive Convertible Debentures, redeemed, converted, exchanged or repurchased
by the Company  pursuant to Article X or canceled,  or transferred for part of a
Global  Debenture,  the  principal  amount of such Global  Debenture  shall,  in
accordance  with the standing  procedures and  instructions of the Depositary be
reduced or increased,  as the case may be, and an  endorsement  shall be made on
such Global  Debenture  by, or at the  direction of, the Trustee to reflect such
reduction or increase.

               (e) Any  Convertible  Debenture  or Common  Stock issued upon the
conversion or exchange of a Convertible  Debenture  that,  prior to the Transfer
Restriction  Termination  Date,  is  purchased  or owned by the  Company  or any
Affiliate  thereof  may not be resold by the  Company or such  Affiliate  unless
registered  under the Securities Act or resold pursuant to an exemption from the
registration  requirements of the Securities Act in a transaction  which results
in such  Convertible  Debentures or Common Stock,  as the case may be, no longer
being "restricted securities" (as defined under Rule 144).

               Section 2.5 INTEREST.

               (a) Each Convertible  Debenture will bear interest at the rate of
7:% per annum  (the  "Coupon  Rate")  from April 12,  2000  until the  principal
thereof becomes due and payable, and on any overdue principal and (to the extent
that  payment of such  interest  is  enforceable  under  applicable  law) on any
overdue  installment  of  interest  at the Coupon  Rate,  compounded  quarterly,

<PAGE>
                                       16

payable  (subject  to the  provisions  of Article  XI)  quarterly  in arrears on
January 15,  April 15, July 15 and October 15 of each year (each,  an  "Interest
Payment  Date"),  commencing  on July 15, 2000, to the Person in whose name such
Convertible Debenture or any Predecessor Convertible Debenture is registered, at
the close of business on the record date for such  interest  installment,  which
shall be the close of  business  on the  fifteenth  day  prior to that  Interest
Payment Date.

               (b)  The  amount  of  interest  payable  for any  period  will be
computed on the basis of a 360-day year of twelve 30-day  months.  The amount of
interest  payable for any period shorter than a full quarterly  period for which
interest is computed, will be computed on the basis of the actual number of days
elapsed  per  30-day  month.  In the event  that any date on which  interest  is
payable on the  Convertible  Debentures  is not a Business  Day, then payment of
interest  payable on such date will be made on the next succeeding day that is a
Business Day (and  without any interest or other  payment in respect of any such
delay),  except that,  if such Business Day is in the next  succeeding  calendar
year, such payment shall be made on the immediately  preceding  Business Day, in
each case with the same force and effect as if made on such date.

               (c) If at any  time  the  Trust  is  required  to pay any  taxes,
duties,  assessments  or  governmental  charges of whatever  nature  (other than
withholding  taxes) imposed by the United States, or any other taxing authority,
then,  in any such case,  the Company will pay as additional  sums  ("Additional
Sums")  such  additional  amounts as shall be  required  so that the net amounts
received  and  retained  by the  Trust  after  paying  any such  taxes,  duties,
assessments or other governmental  charges will not be less than the amounts the
Trust  would have  received  had no such  taxes,  duties,  assessments  or other
government  charges  been  imposed  so long as the  Trust is the  holder  of the
Convertible Debentures.

               The   definitive   Convertible   Debentures   shall  be  printed,
lithographed  or  engraved on steel  engraved  borders or may be produced in any
other  manner,  all as  determined by the officers  executing  such  Convertible
Debentures, as evidenced by their execution of such Convertible Debentures.

               Section  2.6   AUTHENTICATION   AND   DELIVERY   OF   CONVERTIBLE
Debentures.

               At any  time  and  from  time to time  after  the  execution  and
delivery of this Indenture,  the Company may deliver  Convertible  Debentures in
the aggregate principal amount of up to $185,567,010  executed by the Company to
the Trustee for authentication, and the Trustee shall thereupon authenticate and
make available for delivery such  Convertible  Debentures to or upon the written
order of the Company, signed by both (i) the chairman of its Board of Directors,
or any vice  chairman of its Board of  Directors,  or its  president or any vice
president and (ii) its treasurer or any assistant  treasurer or its secretary or
any  assistant  secretary,  without  any  further  action  by  the  Company.  In
authenticating   such  Convertible   Debentures  and  accepting  the  additional
responsibilities   under  this   Indenture  in  relation  to  such   Convertible
Debentures,  the Trustee  shall be provided  with and  (subject to Section  6.1)
shall be fully protected in relying upon:

<PAGE>
                                       17

               (a) a copy of any  resolution  or  resolutions  of the  Board  of
          Directors relating to the issuance of such Convertible Debentures,  in
          each case certified by the secretary or an assistant  secretary of the
          Company;

               (b) a supplemental indenture, if any;

               (c) an Opinion of Counsel,  prepared in  accordance  with Section
          15.5, which shall state that the Convertible Debentures have been duly
          authorized,  and, when  authenticated and delivered by the Trustee and
          issued by the  Company  in the manner  and  subject to any  conditions
          specified  in such  Opinion  of  Counsel,  will  constitute  valid and
          legally binding  obligations of the Company  enforceable in accordance
          with  their  terms,  subject  to  applicable  bankruptcy,  insolvency,
          fraudulent  conveyance,  reorganization  or other laws  relating to or
          affecting  the  enforcement  of  creditors'  rights  generally  and by
          general   equitable    principles,    regardless   of   whether   such
          enforceability is considered in a proceeding in equity or at law.

               Notwithstanding the provisions of the preceding paragraph, if the
Convertible Debentures are not to be originally issued at one time, it shall not
be necessary to deliver the  resolution of the Board of Directors and Opinion of
Counsel otherwise  required pursuant to such preceding  paragraph at or prior to
the time of authentication  of each Convertible  Debenture if such documents are
delivered at or prior to the time of  authentication  upon original  issuance of
the first  Convertible  Debentures to be issued.  After the original issuance of
the first  Convertible  Debenture to be issued,  any separate written request by
the Company that the Trustee  authenticate  Convertible  Debentures for original
issuance  will be  deemed to be a  certification  by the  Company  that it is in
compliance with all conditions precedent provided for in this Indenture relating
to the authentication and delivery of such Convertible Debentures.

               The Trustee shall have the right to decline to  authenticate  and
deliver any Convertible  Debentures under this Section if the Trustee is advised
by counsel in good faith that the issuance of such Convertible  Debentures would
expose the Trustee to personal liability or is unlawful.

               If the Convertible Debentures are to be issued in the form of one
or more Global Debentures, then the Company shall execute and the Trustee shall,
in  accordance  with this Section,  authenticate  and deliver one or more Global
Debentures  that (i) shall represent and shall be denominated in an amount equal
to the aggregate  principal amount of all of the Convertible  Debentures  issued
and not yet  cancelled,  (ii) shall be registered in the name of the  Depositary
for such  Global  Debenture  or  Convertible  Debentures  or the nominee of such
Depositary,  (iii)  shall be  delivered  by the  Trustee to such  Depositary  or
pursuant  to  such  Depositary's  instructions  and  (iv)  shall  bear a  legend
substantially  to the  following  effect:  "Unless and until it is  exchanged in
whole or in part for Convertible  Debentures in definitive registered form, this
Convertible Debenture may not be transferred except as a whole by the Depositary
to the  nominee  of the  Depositary  or by a nominee  of the  Depositary  to the
Depositary or another nominee of the Depositary or by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary."

                                       18

               Each  Depositary  must, at the time of its designation and at all
times while it serves as Depositary,  be a clearing agency  registered under the
Exchange Act and any other applicable  statute or regulation to be so registered
to act as such depositary.

               Section 2.7 EXECUTION OF CONVERTIBLE DEBENTURES.  The Convertible
Debentures shall be signed on behalf of the Company by the chairman of its Board
of Directors,  or any vice chairman of its Board of Directors,  or its president
or any vice  president and attested by its treasurer or any assistant  treasurer
or its secretary or any assistant  secretary,  under its  corporate  seal.  Such
signatures may be the manual or facsimile signatures of such officers.  The seal
of the Company may be in the form of a facsimile  thereof and may be  impressed,
affixed,  imprinted  or  otherwise  reproduced  on the  Convertible  Debentures.
Typographical  and other minor errors or defects in any such reproduction of the
seal or any such signature  shall not affect the validity or  enforceability  of
any Convertible  Debenture that has been duly authenticated and delivered by the
Trustee.

               In case any  officer of the  Company who shall have signed any of
the Convertible Debentures shall cease to be such officer before the Convertible
Debenture  so signed  shall be  authenticated  and  delivered  by the Trustee or
disposed of by the  Company,  such  Convertible  Debenture  nevertheless  may be
authenticated  and delivered or disposed of as though the person who signed such
Convertible  Debenture had not ceased to be such officer of the Company; and any
Convertible Debenture may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Convertible Debenture,  shall be the
proper  officers  of the  Company,  although  at the date of the  execution  and
delivery of this Indenture any such person was not such an officer.

               Section 2.8 CERTIFICATE OF AUTHENTICATION.  Only such Convertible
Debentures as shall bear thereon a certificate of  authentication  substantially
in the form  attached  hereto as a part of Exhibit A and executed by the Trustee
by the manual signature of one of its authorized  signatories  shall be entitled
to the benefits of this Indenture or be valid or obligatory for any purpose. The
execution  of such  certificate  by the Trustee upon any  Convertible  Debenture
executed  by the  Company  shall be  conclusive  evidence  that the  Convertible
Debenture so authenticated has been duly  authenticated and delivered  hereunder
and that the Holder is entitled to the benefits of this Indenture.

               Notwithstanding the foregoing, if any Convertible Debenture shall
have been duly  authenticated and delivered  hereunder but never issued and sold
by the Company,  the Company  shall  deliver such  Convertible  Debenture to the
Trustee for  cancellation  as provided in Section 2.12  together  with a written
statement  (which need not comply with Section 15.5 and need not be  accompanied
by an Opinion of Counsel) stating that such Convertible Debenture has never been
issued  and  sold by the  Company,  for all  purposes  of  this  Indenture  such
Convertible  Debenture  shall be  deemed  never to have been  authenticated  and
delivered  hereunder  and  shall  never  be  entitled  to the  benefits  of this
Indenture.

               Section  2.9  DENOMINATION  AND DATE OF  CONVERTIBLE  DEBENTURES;
PAYMENTS OF INTEREST.

               Convertible  Debentures shall be issuable in denominations of $10
and any integral multiple thereof. The Convertible Debentures shall be numbered,
lettered,  or otherwise  distinguished in such manner or in accordance with such
plans as the officers of the Company  executing the same may determine  with the
approval  of the  Trustee  as  evidenced  by the  execution  and  authentication
thereof.

               Each  Convertible  Debenture  shall  be  dated  the  date  of its
authentication.

               The term  "record  date" as used  with  respect  to any  interest
payment date (except for payment of defaulted  interest) shall mean the close of
business on the fifteenth day preceding such interest  payment date,  whether or
not such record date is a Business Day.

               Any interest on any Convertible  Debenture which is payable,  but
is not  punctually  paid or duly  provided  for, on any interest  payment  date,
subject  to the  provisions  of  Article XI  (called  "defaulted  interest"  for
purposes of this Section) shall  forthwith  cease to be payable to the Holder on
the  relevant  record  date by virtue of his having been such  Holder;  and such
defaulted interest may be paid by the Company,  at its election in each case, as
provided in clause (1) or clause (2) below:

               (1) The  Company  may  elect  to make  payment  of any  defaulted
          interest to the persons in whose names any such Convertible Debentures
          (or  their   respective   predecessor   Convertible   Debentures)  are
          registered  at the close of business on a special  record date for the
          payment  of such  defaulted  interest,  which  shall  be  fixed in the
          following  manner.  The Company shall notify the Trustee in writing of
          the  amount  of  defaulted  interest  proposed  to  be  paid  on  each
          Convertible  Debentures and the date of the proposed  payment,  and at
          the same time the Company  shall deposit with the Trustee an amount of
          money equal to the aggregate  amount proposed to be paid in respect of
          such defaulted interest or shall make arrangements satisfactory to the
          Trustee for such deposit  prior to the date of the  proposed  payment,
          such money when  deposited  to be held in trust for the benefit of the
          persons  entitled  to  such  defaulted  interest  as  in  this  clause
          provided.  Thereupon the Trustee  shall fix a special  record date for
          the  payment of such  defaulted  interest  in  respect of  Convertible
          Debentures which shall not be more than 15 nor less than 10 days prior
          to the date of the  proposed  payment  and not less than 10 days after
          the receipt by the Trustee of the notice of the proposed payment.  The
          Trustee shall promptly  notify the Company of such special record date
          and, in the name and at the expense of the Company  shall cause notice
          of the  proposed  payment of such  defaulted  interest and the special
          record date thereof to be mailed, first class postage prepaid, to each
          Holder at his address as it appears in the Security Register, not less
          than 10 days prior to such special record date. Notice of the proposed
          payment  of such  defaulted  interest  and  the  special  record  date
          therefor having been mailed as aforesaid,  such defaulted  interest in
          respect of Convertible Debentures shall be paid to the person in whose
          names such  Convertible  Debentures (or their  respective  predecessor
          Convertible Debentures) are registered on such special record date and
          such  defaulted  interest  shall no longer be payable  pursuant to the
          following  clause  (2).  (2)  The  Company  may  make  payment  of any

<PAGE>
                                       20

          defaulted  interest on the Convertible  Debentures in any other lawful
          manner  not  inconsistent  with  the  requirements  of any  securities
          exchange on which the Convertible  Debentures may be listed,  and upon
          such notice as may be  required by such  exchange,  if,  after  notice
          given by the Company to the Trustee of the proposed  payment  pursuant
          to this clause,  such manner of payment shall be deemed practicable by
          the Trustee.

               Subject  to  the  foregoing  provisions  of  this  Section,  each
Convertible  Debenture  delivered  under this  Indenture  upon transfer of or in
exchange  for or in lieu of any  other  Convertible  Debenture  shall  carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Convertible Debenture.

               In the case of any Convertible  Debenture which is converted into
Common  Stock of the  Company  after any record date and on or prior to the next
succeeding  Interest  Payment Date (other than any  Convertible  Debenture whose
Maturity is prior to such Interest Payment Date), interest whose Stated Maturity
is on such Interest  Payment Date shall be payable on such Interest Payment Date
notwithstanding  such conversion,  and such interest  (whether or not punctually
paid or duly  provided  for)  shall be paid to the  Person  in whose  name  that
Convertible  Debenture (or one or more  Predecessor  Convertible  Debentures) is
registered  at the  close  of  business  on  such  record  date.  However,  if a
redemption date falls between a record date and the subsequent  Interest Payment
Date, the amount of such payment shall include  accumulated  and unpaid interest
accrued to, but excluding,  such redemption date. Except as otherwise  expressly
provided  in the  first  two  sentences  of this  paragraph,  in the case of any
Convertible  Debenture  which is converted,  interest  whose Stated  Maturity is
after the date of conversion of such Convertible Debenture shall not be payable.

               Section 2.10 REGISTRATION,  TRANSFER AND EXCHANGE.The  provisions
of this Section  2.10 shall be subject in their  entirety to the  provisions  of
Section  2.4.  The Company  will cause to be kept at each office or agency to be
maintained  for the purpose as  provided in Section 3.2 a register or  registers
(herein sometimes referred to as the "Security  Register") in which,  subject to
such  reasonable  regulations as it may prescribe,  the Company will provide for
the  registration  and the  registration  of the  transfer  or  exchange  of the
Convertible  Debentures.  The  Trustee  is  hereby  appointed  and  accepts  the
appointment  as Registrar (the  "Registrar")  for purposes of  registering,  and
registering  transfers  of,  the  Convertible  Debentures.  Upon  surrender  for
registration  of transfer  of any  Convertible  Debenture  at any such office or
agency to be maintained  for the purpose as provided in Section 3.2, the Company
shall execute and the Trustee shall authenticate and make available for delivery
in the name of the  transferee  or  transferees a new  Convertible  Debenture or
Convertible  Debentures and of a like tenor and containing the same terms (other
than the principal  amount thereof,  if more than one  Convertible  Debenture is
executed, authenticated and delivered in respect to any Convertible Debenture so
presented,  in which  case  the  aggregate  principal  amount  of the  executed,
authenticated  and delivered  Convertible  Debentures  shall equal the principal
amount  of  the  Convertible   Debenture   presented  in  respect  thereof)  and
conditions.

               At the  option  of the  Holder  thereof,  Convertible  Debentures
(other than a Global Debenture,  except as set forth below) may be exchanged for
a   Convertible   Debenture  or   Convertible   Debentures   having   authorized
denominations and an equal aggregate  principal  amount,  upon surrender of such
Convertible  Debentures  to be exchanged at the agency of the Company that shall

<PAGE>
                                       21

be maintained for such purpose in accordance  with Section 3.2 and upon payment,
if the Company shall so require,  of the charge hereinafter  provided.  Whenever
any Convertible  Debentures are so surrendered  for exchange,  the Company shall
execute,  and the  Trustee  shall  authenticate  and  deliver,  the  Convertible
Debentures  which the Holder  making the  exchange is  entitled to receive.  All
Convertible Debentures surrendered upon any exchange or transfer provided for in
this Indenture shall be promptly  cancelled by the Trustee and the Trustee shall
dispose of such  cancelled  Convertible  Debentures in its customary  manner and
will deliver a certificate of cancellation thereof to the Company.

               All Convertible  Debentures  issued upon any transfer or exchange
of Convertible  Debentures shall be the valid and legally binding obligations of
the Company,  evidencing  the same debt, and entitled to the same benefits under
this Indenture,  as the Convertible Debentures surrendered upon such transfer or
exchange.

               Every   Convertible   Debenture   presented  or  surrendered  for
registration of transfer or exchange shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form  satisfactory to the Company and the Trustee duly executed by the Holder
thereof or his attorney duly authorized in writing.

               No  service   charge   shall  be  made  to  the  Holder  for  any
registration of transfer or exchange of Convertible Debentures,  but the company
may require  payment of a sum sufficient to cover any tax or other  governmental
charge  that may be imposed in  connection  with any  transfer  or  exchange  of
Convertible  Debentures,  other than exchanges pursuant to Sections 2.13, 8.5 or
12.5 not involving any transfer.

               The Company  shall not be  required  (i) to issue,  register  the
transfer of or exchange any Convertible  Debenture  during a 15-day period prior
to the day of mailing of the relevant  notice of  redemption or (ii) to register
the transfer of or exchange any Convertible Debenture so selected for redemption
in whole or in part,  except,  in the case of any  Convertible  Debenture  to be
redeemed in part, the portion thereof not redeemed.

               Notwithstanding any other provisions of this Section 2.10, unless
and until it is  exchanged  in whole or in part for  Convertible  Debentures  in
definitive registered form, a Global Debenture  representing all or a portion of
the  Convertible  Debentures  may not be  transferred  except  as a whole by the
Depositary to a nominee of such Depositary or by a nominee of such Depositary to
such  Depositary or another  nominee of such Depositary or by such Depositary or
any such  nominee  to a  successor  Depositary  or a nominee  of such  successor
Depositary.

               If at any  time the  Depositary  for any  Convertible  Debentures
represented  by one or more Global  Debentures  notifies  the Company that it is
unwilling or unable to continue as Depositary for such Convertible Debentures or
if at any time the Depositary for such Convertible Debentures shall no longer be
eligible  under Section 2.6, the Company  shall  appoint a successor  Depositary
with respect to such Convertible Debentures.  If a successor Depositary for such
Convertible  Debentures is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility, as the case
may be, the Company's  election that such Convertible  Debentures be represented
by one or more Global  Debentures  shall no longer be effective  and the Company
will execute, and the Trustee,  upon receipt of an Officers' Certificate for the

<PAGE>
                                       22

authentication  and  delivery  of  definitive   Convertible   Debentures,   will
authenticate and deliver,  Convertible Debentures in definitive registered form,
in any authorized  denominations,  in an aggregate principal amount equal to the
principal amount of the Global Debenture or Convertible Debentures  representing
such Convertible Debentures in exchange for such Global Debenture or Convertible
Debentures.

               The Company may at any time and in its sole discretion  determine
that  the  Convertible  Debentures  issued  in the  form of one or  more  Global
Debentures shall no longer be represented by a Global  Debenture.  In such event
the  Company  will  execute,  and the  Trustee,  upon  receipt  of an  Officers'
Certificate  for the  authentication  and  delivery  of  definitive  Convertible
Debentures, will authenticate and deliver,  Convertible Debentures in definitive
registered  form, in any  authorized  denominations,  in an aggregate  principal
amount equal to the principal  amount of the Global  Debenture,  in exchange for
such Global Debenture.

               If an Event of Default  occurs and is continuing  with respect to
Convertible Debentures issued in the form of one or more Global Debentures, upon
written notice from the Depositary,  the Company will execute,  and the Trustee,
upon receipt of an Officers'  Certificate for the authentication and delivery of
definitive Convertible  Debentures,  will authenticate and deliver,  Convertible
Debentures in definitive registered form, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Global Debenture
or Convertible Debentures, representing such Convertible Debentures, in exchange
for such Global Debenture or Convertible Debentures.

               If  specified  by the  Company,  the  Depositary  for such Global
Debenture  may surrender  such Global  Debenture in exchange in whole or in part
for  Convertible  Debentures in definitive  registered form on such terms as are
acceptable  to the Company and such  Depositary.  Thereupon,  the Company  shall
execute, and the Trustee shall authenticate and deliver,  without service charge
to the Holder:

               (i) to the Person  specified by such Depositary a new Convertible
          Debenture or Convertible Debentures,  of any authorized  denominations
          as requested by such Person, in an aggregate principal amount equal to
          and in exchange for such  Person's  beneficial  interest in the Global
          Debenture; and

               (ii) to such Depositary a new Global  Debenture in a denomination
          equal to the difference,  if any,  between the principal amount of the
          surrendered  Global  Debenture and the aggregate  principal  amount of
          Convertible Debentures  authenticated and delivered pursuant to clause
          (i) above.

               Upon  the  exchange  of  a  Global   Debenture  for   Convertible
Debentures in definitive  registered  form,  in authorized  denominations,  such
Global Debenture shall be cancelled by the Trustee or an agent of the Company or
the Trustee.  Convertible  Debentures  in definitive  registered  form issued in
exchange  for a  Global  Debenture  pursuant  to  this  Section  2.10  shall  be
registered in such names and in such authorized  denominations as the Depositary
for such Global Debenture,  pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee or agent of the Company or
the Trustee. The Trustee or such agent shall deliver such Convertible Debentures

<PAGE>
                                       23

to or as directed by the Persons in whose names such Convertible  Debentures are
so registered.

               Section  2.11  MUTILATED,  DEFACED,  DESTROYED,  LOST AND  STOLEN
CONVERTIBLE  DEBENTURES.   In  case  any  temporary  or  definitive  Convertible
Debenture  shall become  mutilated or defaced or be  destroyed,  lost or stolen,
then,  in  the  absence  of  notice  to the  Company  or the  Trustee  that  the
Convertible  Debenture has been acquired by a bona fide  purchaser,  the Company
shall execute,  and upon the written request of any officer of the Company,  the
Trustee shall  authenticate  and make  available for delivery a new  Convertible
Debenture  and of like  tenor and  principal  amount and with the same terms and
conditions,  bearing a number not contemporaneously outstanding, in exchange and
substitution  for the mutilated or defaced  Convertible  Debenture or in lieu of
and substitution for the Convertible Debenture so destroyed,  lost or stolen. In
every case the applicant for a substitute Convertible Debenture shall furnish to
the  Company  and to the  Trustee and to any agent of the Company or the Trustee
such  security or indemnity  as may be required by them to indemnify  and defend
and to save each of them  harmless  and, in every case of  destruction,  loss or
theft, evidence to their satisfaction of the destruction,  loss or theft of such
Convertible Debenture and of the ownership thereof and in the case of mutilation
or defacement  shall surrender the Convertible  Debenture to the Trustee or such
agent.

               Upon the issuance of any substitute  Convertible  Debenture,  the
Company may require  the payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee or its agent) connected
therewith.  In case any  Convertible  Debenture which has matured or is about to
mature or has been  called for  redemption  in full shall  become  mutilated  or
defaced or be destroyed,  lost or stolen,  the Company may, instead of issuing a
substitute  Convertible  Debenture,  pay or  authorize,  the payment of the same
(without  surrender  thereof  except  in the  case  of a  mutilated  or  defaced
Convertible Debenture);  provided,  however, that the applicant for such payment
shall  furnish to the Company and to the Trustee and any agent of the Company or
the Trustee  such  security or indemnity as any of them may require to save each
of them  harmless,  and,  in  every  case of  destruction,  loss or  theft,  the
applicant shall also furnish to the Company and the Trustee and any agent of the
Company or the Trustee evidence to their  satisfaction of the destruction,  loss
or theft of such Convertible Debenture and of the ownership thereof.

               Every  substitute  Convertible  Debenture  issued pursuant to the
provisions of this Section by virtue of the fact that any Convertible  Debenture
is  destroyed,  lost  or  stolen  shall  constitute  an  additional  contractual
obligation  of the  Company,  whether  or not  the  destroyed,  lost  or  stolen
Convertible  Debenture  shall be at any time  enforceable by anyone and shall be
entitled to all the benefits of (but shall be subject to all the  limitations of
rights set forth in) this Indenture equally and proportionately with any and all
other Convertible  Debentures duly  authenticated and delivered  hereunder.  All
Convertible  Debentures  shall be held upon the express  condition  that, to the
extent permitted by law, the foregoing  provisions are exclusive with respect to
the  replacement  or payment of mutilated,  defaced,  destroyed,  lost or stolen
Convertible  Debentures  and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the  replacement  or payment of negotiable  instruments or other
securities without their surrender.

               Section   2.12   CANCELLATION  OF  CONVERTIBLE   DEBENTURES.  All
Convertible   Debentures  surrendered  for  payment,   redemption,   conversion,
registration  of  transfer  or  exchange,  or for credit  against any payment in
respect of a sinking or analogous fund,  shall, if surrendered to the Company or
any agent of the  Company  or the  Trustee,  be  delivered  to the  Trustee  for
cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no
Convertible  Debentures  shall be issued in lieu  thereof,  except as  expressly
permitted by any of the  provisions  of this  Indenture.  The Company may at any
time  deliver  to  the  Trustee  for  cancellation  any  Convertible  Debentures
previously authenticated hereunder which the Company has not issued and sold and
all  Convertible  Debentures  so  delivered  shall be promptly  cancelled by the
Trustee.  If the Company shall acquire any of the Convertible  Debentures,  such
acquisition   shall  not  operate  as  a  redemption  or   satisfaction  of  the
indebtedness  represented by such  Convertible  Debentures  unless and until the
same are delivered to the Trustee for  cancellation.  All cancelled  Convertible
Debentures  shall be  disposed of in  accordance  with the  Trustee's  customary
practices.

               Section  2.13  TEMPORARY   CONVERTIBLE   DEBENTURES. Pending  the
preparation of definitive  Convertible  Debentures,  the Company may execute and
the  Trustee  shall  authenticate  and make  available  for  delivery  temporary
Convertible   Debentures  (printed,   lithographed,   typewritten  or  otherwise
reproduced,  in  each  case  in  form  reasonably  acceptable  to the  Trustee).
Temporary   Convertible   Debentures   shall  be  issuable  in  any   authorized
denomination,  and  substantially  in the  form  of the  definitive  Convertible
Debentures  but  with  such  omissions,  insertions  and  variations  as  may be
appropriate for temporary  Convertible  Debentures,  all as may be determined by
the  Company  with  the  reasonable   concurrence  of  the  Trustee.   Temporary
Convertible  Debentures  may contain such  reference to any  provisions  of this
Indenture as may be appropriate.  Every temporary Convertible Debenture shall be
executed  by the  Company  and be  authenticated  by the  Trustee  upon the same
conditions and in substantially  the same manner,  and with like effect,  as the
definitive Convertible Debentures.  Without unreasonable delay the Company shall
execute  and shall  furnish  definitive  Convertible  Debentures  and  thereupon
temporary Convertible Debentures may be surrendered in exchange therefor without
charge to the Holder at each  office or agency to be  maintained  by the Company
for that purpose pursuant to Section 3.2, and the Trustee shall authenticate and
make  available  for  delivery  in  exchange  for  such  temporary   Convertible
Debentures  an  equal  aggregate  principal  amount  of  definitive  Convertible
Debentures  of  authorized  denominations.  Until so  exchanged,  the  temporary
Convertible  Debentures  shall be  entitled  to the  same  benefits  under  this
Indenture as definitive Convertible Debentures.

               Section 2.14 CUSIP NUMBERS.

               The Company in issuing the Convertible Debentures may use "CUSIP"
numbers (if then  generally in use),  and, if so, the Trustee  shall use "CUSIP"
numbers in notices of redemption as a convenience to Holders;  PROVIDED that any
such notice may state that no  representation  is made as to the  correctness of
such numbers either as printed on the Convertible  Debentures or as contained in
any notice of a  redemption  and that  reliance  may be placed only on the other
identification  numbers  printed  on the  Convertible  Debentures,  and any such
redemption  shall not be affected by any defect in or omission of such  numbers.
The  Company  will  promptly  notify the  Trustee  of any change in the  "CUSIP"
numbers.

                            COVENANTS OF THE COMPANY


               Section 3.1 PAYMENT OF PRINCIPAL AND INTEREST.

               The  Company   covenants  and  agrees  for  the  benefit  of  the
Convertible  Debentures that it will duly and punctually pay or cause to be paid
the  principal  of, and  interest  on,  each of the  Convertible  Debentures  in
accordance with the terms of such Convertible  Debentures and of this Indenture.
The interest on Convertible  Debentures  (together  with any additional  amounts
payable pursuant to the terms of such Convertible  Debentures)  shall be payable
only to or upon the written  order of the  Holders  thereof and at the option of
the Company may be paid by wire transfer or by mailing  checks for such interest
payable to or upon the written order of such Holders at their last  addresses as
they appear on the Security Register.

               Payment  of  principal  of and any  interest  on any  Convertible
Debenture  in  definitive  global  form  shall be made to the  Person or Persons
specified therein.  Except as provided in the preceding paragraph,  the Company,
the Trustee and any agent of the Company and the Trustee shall treat a Person as
the  Holder of such  principal  amount  of  Outstanding  Convertible  Debentures
represented by a Global  Debenture as shall be specified in a written  statement
of the Holder of such Global Debenture.

               Section  3.2  OFFICES  FOR  PAYMENT,  ETC.  So long as any of the
Convertible  Debentures  remain  outstanding,  the  Company  will  maintain  the
following: an office or agency in the Borough of Manhattan, City of New York (a)
where the  Convertible  Debentures  may be presented for payment,  (b) where the
Convertible  Debentures  may be presented for  registration  of transfer and for
exchange as provided in this Indenture, and (c) where notices and demands may be
served  upon the  Company  in  respect of the  Convertible  Debentures,  or this
Indenture.

               The  Company  will  give to the  Trustee  written  notice  of the
location of any such office or agency and of any change of location thereof.  In
case the  Company  shall fail to so  designate  or  maintain  any such office or
agency or shall fail to give such notice of the location or of any change in the
location  thereof,  presentations  and  demands  may be made and  notices may be
served at the  Corporate  Trust  Office.  The Trustee is hereby  appointed,  and
accepts its appointment as, Paying Agent.

               Section 3.3 PAYING AGENTS. Whenever  the Company  shall appoint a
Paying Agent other than the Trustee with respect to the Convertible  Debentures,
it will  cause  such  Paying  Agent to execute  and  deliver  to the  Trustee an
instrument  in which such Paying Agent shall agree with the Trustee,  subject to
the provisions of this Section:

               (a)  that it will  hold all sums  received  by it as such  Paying
          Agent  for  the  payment  of  the  principal  of or  interest  on  the
          Convertible  Debentures (whether such sums have been paid to it by the
          Company or by any other  obligor  on the  Convertible  Debentures)  in
          trust for the benefit of the Holders of the Convertible  Debentures or

<PAGE>
                                       26

          of the  Trustee,  and upon the  occurrence  of an Event of Default and
          upon the  written  request  of the  Trustee,  pay  over all such  sums
          received by it to the Trustee; and

               (b) that it will give the Trustee  written  notice of any failure
          by the Company (or by any other obligor on the Convertible Debentures)
          to make any payment of the principal of or interest on the Convertible
          Debentures  when the same shall be due and payable.  The Company will,
          on or prior to each due date of the  principal  of or  interest on the
          Convertible  Debentures,  deposit in a timely  manner  with the Paying
          Agent a sum  sufficient to pay such  principal or interest so becoming
          due,  and (unless  such Paying  Agent is the Trustee) the Company will
          promptly notify the Trustee of any failure to take such action.

               If the Company  shall act as its own Paying Agent with respect to
the Convertible Debentures, it will, on or before each due date of the principal
of or interest on the Convertible  Debentures,  set aside, segregate and hold in
trust  for the  benefit  of the  holders  of the  Convertible  Debentures  a sum
sufficient  to pay such  principal or interest so becoming due. The Company will
promptly notify the Trustee of any failure to take such action.

               Section  3.4 WRITTEN  STATEMENT  TO  TRUSTEE.  The  Company  will
deliver to the Trustee, within 120 days after the end of each fiscal year of the
Company ending after the date hereof, a brief certificate (which need not comply
with Section 15.5) from the principal executive, financial or accounting officer
of the Company as to his or her knowledge,  after due inquiry,  of the Company's
compliance  with  all  conditions  and  covenants  under  this  Indenture  (such
compliance to be determined without regard to any period of grace or requirement
of notice  provided  under this  Indenture),  and if the Company shall not be in
compliance,  specifying all such defaults or  non-compliance  and the nature and
status  thereof.  The Company  shall deliver to the Trustee  promptly  after the
Company  becomes  aware of the  occurrence  of any Event of  Default or an event
which,  with notice or the lapse of time or both,  would  constitute an Event of
Default,  an Officers'  Certificate  setting  forth the details of such Event of
Default  or default  and the  action  which the  Company  proposes  to take with
respect thereto.

               Section  3.5   LIMITATION   ON   DIVIDENDS;   TRANSACTIONS   WITH
AFFILIATES. If  any  Convertible  Debentures are outstanding and (i) there shall
have occurred any Event of Default or any event that,  with the giving of notice
or lapse of time or  both,  would  constitute  an  Event  of  Default,  (ii) the
Guarantor  shall be in default with respect to its payment or other  obligations
under the Preferred Securities Guarantee or the Common Securities Guarantee,  or
(iii) the Company  shall have given notice of its election to defer  payments of
interest on Convertible  Debentures by extending the interest  payment period as
provided  in Article XI and such  period,  or any  extension  thereof,  shall be
continuing,  then the Company shall not (a) declare or pay any dividend on, make

payment  with  respect to, any of its  Capital  Stock or (b) make any payment of
interest,  principal or premium,  if any, on or repay,  repurchase or redeem any
debt  securities  issued by the  Company  that rank pari passu with or junior in
interest to the  Convertible  Debentures  or make any  guarantee  payments  with
respect to any guarantee by the Company of the debt securities of any subsidiary
of the Company if such guarantee  ranks pari passu with or junior in interest to
the Convertible  Debentures (other than (i) as a result of a reclassification of
the Capital  Stock of the Company or the exchange or  conversion of one class or
series of the Capital  Stock of the  Company for another  class or series of the

<PAGE>

exchange  provisions of such Capital Stock or the security being  converted into
or exchanged for such Capital Stock,  (iii) dividends or distributions in Common

Trust Securities remain  outstanding,  the Company will (a) maintain 100% direct
or  indirect  ownership  of the Common  Securities  of Viatel  Trust;  provided,
however,  that any permitted  successor of the Company under this  Indenture may
succeed  to the  Company's  ownership  of the  Common  Securities,  (b)  use its
reasonable  efforts to cause  Viatel  Trust (i) to remain a  statutory  business
trust,  except in connection with the distribution of Convertible  Debentures to
the holders of Trust  Securities in liquidation of Viatel Trust,  the redemption
of  all  of  the  Trust   Securities  of  Viatel  Trust,  or  certain   mergers,
consolidations or amalgamations,  each as permitted by the Declaration, and (ii)
to continue to be classified as a grantor trust for United States federal income
tax purposes and (c) to use its reasonable efforts to cause each holder of Trust
Securities  to be  treated as owning an  undivided  beneficial  interest  in the
Convertible Debentures.

               Section 3.7  EXISTENCE.Subject to Article IX, the Company will do
or cause to be done all things  necessary to preserve and keep in full force and
effect its existence,  rights (charter and statutory) and franchises;  provided,

franchise  if the  Board of  Directors  shall  determine  that the  preservation
thereof is no longer desirable in the conduct of the business of the Company and

Holders.

the Holders of the Convertible Debentures:

               (a) semiannually and not more than 15 days after each record date
          for the  payment  of  interest  on  such  Convertible  Debentures,  as
          hereinabove specified, as of such record date, and

<PAGE>
                                       28

               (b) at such other times as the Trustee may reasonably  request in
          writing,  within 30 days  after  receipt  by the  Company  of any such
          request,  such list to be as of a date not more than 15 days  prior to
          the time such  information is furnished,  provided that if and so long
          as the Trustee shall be the Registrar, such list shall not be required
          to be furnished.

               Section 4.2 PRESERVATION AND DISCLOSURE OF HOLDERS OF CONVERTIBLE
DEBENTURES'  LISTS.  (a) The Trustee shall preserve,  in as current a form as is
reasonably  practicable,  all  information  as to the names and addresses of the
Holders of Convertible Debentures contained in the most recent list furnished to
it as provided in Section 4.1 or  maintained  by the Trustee in its  capacity as
Registrar,  if so acting.  The Trustee may destroy any list  furnished  to it as
provided in Section 4.1 upon receipt of a new list so furnished.

               (b) In case  three  or more  Holders  of  Convertible  Debentures
(hereinafter  referred to as  "applicants")  apply in writing to the Trustee and
furnish to the Trustee  reasonable  proof that each such  applicant  has owned a
Convertible  Debenture for a period of at least six months preceding the date of
such  application,  and such  application  states that the applicants  desire to
communicate  with other  Holders of  Convertible  Debentures  (in which case the
applicants  must  all  hold  Convertible  Debentures)  or  with  Holders  of all
Convertible  Debentures  with respect to their  rights  under this  Indenture or
under such Convertible  Debentures and such application is accompanied by a copy
of the form of proxy or other  communication  which such  applicants  propose to
transmit, then the Trustee shall, within five business days after the receipt of
such application, at is election, either

               (i) afford to such applicants access to the information preserved
          at the  time by the  Trustee  in  accordance  with the  provisions  of
          subsection (a) of this Section, or

               (ii)  inform  such  applicants  as to the  approximate  number of
          Holders of Convertible Debentures or of all Convertible Debentures, as
          the case may be, whose names and addresses  appear in the  information
          preserved  at  the  time  by  the  Trustee,  in  accordance  with  the
          provisions of subsection  (a) of this Section,  as to the  approximate
          cost of mailing to such Holders of Convertible  Debentures the form of
          proxy or other  communication,  if any, specified in such application.
          If the Trustee shall elect not to afford to such applicants  access to
          such information,  the Trustee shall, upon the written request of such
          applicants,  mail to each  Holder  of  Convertible  Debentures  or all
          Holders of Convertible Debentures,  as the case may be, whose name and
          address  appears  in the  information  preserved  at the  time  by the
          Trustee in accordance  with the  provisions of subsection  (a) of this
          Section, a copy of the form of proxy or other  communication  which is
          specified in such request,  with reasonable  promptness after a tender
          to the  Trustee  of the  material  to be  mailed  and of  payment,  or
          provision  for the  payment,  of the  reasonable  expenses of mailing,
          unless  within five days after such tender,  the Trustee shall mail to
          such  applicants and file with the Commission  together with a copy of
          the material to be mailed, a written  statement to the effect that, in
          the opinion of the Trustee, such mailing would be contrary to the best
          interests  of the  Holders of  Convertible  Debentures  or could be in
          violation of applicable law. Such written  statement shall specify the
          basis of such opinion.  If the  Commission,  after  opportunity  for a
          hearing  upon the  objections  specified  in the written  statement so
          filed, shall enter an order refusing to sustain any of such objections

<PAGE>
                                       29

          or if,  after the entry of such order  sustaining  one or more of such
          objections,  the Commission  shall find,  after notice and opportunity
          for hearing,  that all the  objections so sustained have been met, and
          shall enter an order so  declaring,  the Trustee  shall mail copies of
          such  material  to all such  Holders of  Convertible  Debentures  with
          reasonable promptness after the entry of such order and the renewal of
          such tender; otherwise the Trustee shall be relieved of any obligation
          or duty to such applicants respecting their application.

               (c) Each and every Holder of Convertible Debentures, by receiving
and holding the same,  agrees with the Company and the Trustee  that neither the
Company nor the  Trustee  nor any agent of the  Company or the Trustee  shall be
held  accountable by reason of the disclosure of any such  information as to the
names and addresses of the Holders of Convertible  Debentures in accordance with
the provisions of subsection (b) of this Section,  regardless of the source from
which such  information  was  derived,  and that the  Trustee  shall not be held
accountable  by reason of mailing any material  pursuant to a request made under
such subsection (b).

               Section 4.3 REPORTS BY THE COMPANY. The Company covenants: (a) to
file with the Trustee,  within 15 days after the Company is required to file the
same with the Commission,  copies of the annual reports and of the  information,
documents,  and  other  reports  (or  copies  of  such  portions  and any of the
foregoing  as the  Commission  may from  time to time by rules  and  regulations
prescribe)  which  the  Company  may be  required  to file  with the  Commission

securities  exchange  as may be  prescribed  from time to time in such rules and
regulations;

               (b) to file with the Trustee and the  Commission,  in  accordance
with rules and regulations prescribed from time to time by the Commission,  such
additional information, documents, and reports with respect to compliance by the
Company with the conditions and covenants  provided for in this Indenture as may
be required from time to time by such rules and regulations; and

               (c) to transmit by mail to the Holders of Convertible  Debentures
in the manner and to the extent  required  by Sections  6.6 and 15.4,  within 30
days  after  the  filing  thereof  with  the  Trustee,  such  summaries  of  any
information, documents, and reports required to be filed by the Company pursuant
to subsections  (a) and (b) of this Section as may be required to be transmitted
to such  Holders by rules and  regulations  prescribed  from time to time by the
Commission.

          proceeding   under  any  applicable   federal  or  state   bankruptcy,
          insolvency,  reorganization  or other similar law or of any other case

          of  the  Company  in an  involuntary  case  or  proceeding  under  any
          applicable federal or state bankruptcy, insolvency,  reorganization or
          other  similar  law  or to  the  commencement  of  any  bankruptcy  or
          insolvency  case or  proceeding  against  it, or the filing by it of a
          petition or answer or consent seeking  reorganization  or relief under
          any  applicable  federal  or state  law,  or the  consent by it to the

               (f) failure by the Company to convert Convertible Debentures into
          shares of Common Stock of the Company upon an appropriate  election by
          a holder of Trust Securities or Convertible Debentures to convert such
          Trust Securities or Convertible  Debentures,  as the case may be, into
          such Common Stock (whether or not conversion or exchange is prohibited
          by the subordination provisions set forth herein); or

               (g) the Viatel  Trust  shall have  voluntarily  or  involuntarily
          dissolved, wound up its business or otherwise terminated its existence
          except  in  connection  with  (i)  the   distribution  of  Convertible
          Debentures  to holders of Trust  Securities  in  liquidation  of their
          interest in the Viatel Trust upon the occurrence of a Special Event or
          upon the  occurrence of events as described in Section 3 of Annex I to
          the Declaration,  (ii) the redemption of all of the outstanding  Trust

          outstanding  Convertible Preferred Securities into Common Stock of the
          Company or (iv) certain mergers, consolidations or amalgamations, each
          as permitted by the Declaration.

               If an Event of Default occurs and is continuing, then and in each
and every such case,  unless the principal of all Convertible  Debentures  shall
have already  become due and  payable,  either the Trustee or the Holders of not
less than 25% in aggregate  principal amount of the Convertible  Debentures then
Outstanding  hereunder,  by notice in writing to the Company (and to the Trustee
if given by such Holders), may declare the entire principal of, plus accrued and
unpaid interest on, all the Convertible  Debentures  (including Additional Sums,
if any, and, to the extent permitted by applicable law,  Compound  Interest,  if
any) and any other amounts  payable  under this  Indenture to be due and payable
immediately,  and upon any such  declaration  the same shall become and shall be
immediately  due and  payable.  These  provisions,  however,  are subject to the
condition  that if at any time after the  principal and other amounts due on the
Convertible  Debentures shall have been so declared due and payable,  and before
any  judgment  or decree  for the  payment  of the  moneys  due shall  have been
obtained or entered as  hereinafter  provided,  the  Company  shall pay or shall
deposit with the Trustee a sum  sufficient  to pay all matured  installments  of
interest,  if any, upon all the Convertible  Debentures and the principal of any
and all  Convertible  Debentures  which shall have become due otherwise  than by
such  acceleration  (with  interest upon such  principal and, to the extent that

<PAGE>
                                       32

payment of such interest is enforceable  under applicable law, Compound Interest
to the date of such  payment)  or  deposit in  Dollars  such  amount as shall be
sufficient  to  cover  reasonable  compensation  to  the  Trustee,  its  agents,
attorneys and counsel and all other expenses and liabilities  incurred,  and all
advances with interest made, by the Trustee, its agents,  attorneys and counsel,
and if any and all defaults under this  Indenture,  other than the nonpayment of
the principal and interest of Convertible Debentures which shall have become due
by such acceleration,  shall have been cured or waived as provided herein,  then
and in every such case the Holders of a majority in aggregate  principal  amount
of the Convertible Debentures then Outstanding, by written notice to the Company
and to the Trustee for the  Convertible  Debentures,  may waive all defaults and
rescind and annul such declaration and its  consequences;  but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent  default
or shall impair any right consequent thereon.

               Section 5.2 COLLECTION OF  INDEBTEDNESS  BY TRUSTEE;  TRUSTEE MAY
PROVE DEBT.The  Company  covenants that (a) in case default shall be made in the
payment of any installment of interest on any of the Convertible Debentures when
such  interest  shall have become due and payable,  and such default  shall have
continued  for a period of 30 days,  or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Convertible Debentures
when the same shall have become due and payable,  whether upon  Maturity or upon
any redemption or by  declaration or otherwise,  then upon demand of the Trustee
for the  Convertible  Debentures,  the  Company  will pay to the Trustee for the
benefit of the Holders of the Convertible  Debentures the whole amount that then
shall have become due and payable on all Convertible Debentures for principal of
or interest,  as the case may be (with interest to the date of such payment upon
the  overdue  principal  and,  to the extent  that  payment of such  interest is
enforceable  under  applicable  law, on overdue  installments of interest at the
same rate as the rate of interest specified in the Convertible Debentures);  and
in addition  thereto,  such further  amount as shall be  sufficient to cover the
costs and expenses of collection,  including reasonable compensation to, and all
expenses and  liabilities  incurred and all advances  with interest made by, the
Trustee and each predecessor Trustee except as a result of its negligence or bad
faith.

               Until such demand is made by the Trustee, the Company may pay the
principal of and interest on the Convertible  Debentures to the persons entitled
thereto,  whether  or not  the  principal  of and  interest  on the  Convertible
Debentures are overdue.

               In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee for the Convertible Debentures,  in its own name and as
trustee of an express  trust,  shall be entitled and  empowered to institute any
action or  proceedings at law or in equity for the collection of the sums so due
and unpaid,  and may  prosecute  any such action or  proceedings  to judgment or
final  decree,  and may enforce any such  judgment or final  decree  against the
Company or other  obligor upon such  Convertible  Debentures  and collect in the
manner  provided by law out of the property of the Company or other obligor upon
such Convertible  Debentures,  wherever situated, the moneys adjudged or decreed
to be payable.

               In case  there  shall  be  pending  proceedings  relative  to the
Company or any other  obligor upon the  securities  under Title 11 of the United
States Code or any other applicable  federal or state bankruptcy,  insolvency or
other  similar law, or in case a receiver,  assignee or trustee in bankruptcy or
reorganization,  liquidator,  sequestrator  or similar  official shall have been
appointed  for or taken  possession of the Company or its property or such other

                                       33

obligor, or in case of any other comparable judicial proceedings relative to the
Company or other obligor under the Convertible Debentures, or to the property of
the Company or such other  obligor,  the  Trustee,  irrespective  of whether the
principal of any Convertible Debentures shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section,  shall be
entitled and empowered, by intervention in such proceeding or otherwise:

               (a) to file and prove a claim or claims  for the whole  amount of
          principal and interest owing and unpaid in respect of the  Convertible
          Debentures,  and to file  such  other  papers or  documents  as may be
          necessary  or  advisable  in order to have the  claims of the  Trustee
          (including any claim for reasonable  compensation to, and all expenses
          and  liabilities  incurred and all advances with interest made by, the
          Trustee and each predecessor  Trustee,  and their  respective  agents,
          attorneys and counsel,  except as a result of negligence or bad faith)
          and of the Holders of Convertible  Debentures  allowed in any judicial
          proceedings  relative  to  the  Company  or  other  obligor  upon  all
          Convertible  Debentures,  or to the  property  of the  Company or such
          obligor, and

               (b) to collect and receive any moneys or other  property  payable
          or deliver  able on any such  claims,  and to  distribute  all amounts
          received  with  respect  to the claims of the  Holders of  Convertible
          Debentures  and of the  Trustee  on  their  behalf;  and any  trustee,
          receiver,  liquidator,  custodian or other similar  official is hereby
          authorized  by each of the Holders of  Convertible  Debentures to make
          payments to the Trustee for the  Convertible  Debentures,  and, in the
          event  that such  Trustee  shall  consent  to the  making of  payments
          directly  to the  Holders of  Convertible  Debentures,  to pay to such
          Trustee  such  amounts  as shall  be  sufficient  to cover  reasonable
          compensation  to, and all  expenses and  liabilities  incurred and all
          advances with interest made by, such Trustee, each predecessor Trustee
          and their  respective  agents,  attorneys  and  counsel  and all other
          amounts due to such  Trustee or any  predecessor  Trustee  pursuant to
          Section 6.7, except as a result of Trustee's negligence or bad faith.

               Nothing herein contained shall be deemed to authorize the Trustee
to  authorize  or  consent  to or accept  or adopt on  behalf  of any  Holder of
Convertible  Debentures any plan of reorganization,  arrangement,  adjustment or
composition  affecting  the  Convertible  Debentures or the rights of any Holder
thereof,  or to  authorize  the  Trustee  to vote in respect of the claim of any
Holder of Convertible Debentures in any such proceeding.

               All  rights  of  action  and  of  asserting   claims  under  this
Indenture,  or under any of the Convertible  Debentures,  may be enforced by the

<PAGE>
                                       34

Trustee for the  Convertible  Debentures  without the  possession  of any of the
Convertible  Debentures  or  the  production  thereof  at  any  trial  or  other
proceedings relative thereto,  any such action or proceedings  instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the expenses,  disbursements and
compensation  of the  Trustee,  each  predecessor  Trustee and their  respective
agents and  attorneys,  shall be for the  ratable  benefit of the Holders of the
Convertible Debentures in respect of which such action was taken.

               In any  proceedings  brought by the Trustee  for the  Convertible
Debentures  (and  also  any  proceedings  involving  the  interpretation  of any
provision of this Indenture to which the Trustee shall be a party),  the Trustee
shall be held to  represent  all the Holders of the  Convertible  Debentures  in
respect to which such action was taken,  and it shall not be  necessary  to make
any Holders of such Convertible Debentures parties to any such proceedings.

               Section 5.3 APPLICATION OF PROCEEDS. Any  moneys collected by the
Trustee for the  Convertible  Debentures  pursuant to this Article in respect of
the Convertible  Debentures  shall be applied in the following order at the date
or dates fixed by such Trustee and, in case of the  distribution  of such moneys

          payments to be made ratably to the persons entitled  thereto,  without

          thereto,  without  discrimination  or  preference,  according  to  the

          principal and interest, respectively; and

               FOURTH: To the payment of the remainder, if any, to the Company.

               Section   5.4   RESTORATION   OF   RIGHTS   ON   ABANDONMENT   OF
PROCEEDINGS. In  case the Trustee for the Convertible  Debentures  or any Holder
shall  have  proceeded  to  enforce  any right  under  this  Indenture  and such
proceedings  shall have been  discontinued or abandoned for any reason, or shall
have been  determined  adversely to the Trustee or to such  Holder,  then and in
every  such case,  subject  to the  determination  in any such  proceeding,  the
Company,  the Trustee and the Holders  shall be restored  respectively  to their
former positions and rights  hereunder,  and all rights,  remedies and powers of
the  Company,  the  Trustee  and the  Holders of  Convertible  Debentures  shall
continue as though no such proceedings had been taken.

               Section  5.5  LIMITATIONS  ON SUITS  BY  HOLDERS  OF  CONVERTIBLE
DEBENTURES.

               No Holder of any  Convertible  Debenture  shall have any right by
virtue or by availing of any provision of this Indenture to institute any action
or proceeding  at law or in equity or in  bankruptcy or otherwise  upon or under

<PAGE>
                                       35

with respect to this Indenture,  or for the appointment of a trustee,  receiver,
liquidator,  custodian  or  other  similar  official  or for  any  other  remedy
hereunder, unless such Holder previously shall have given to the Trustee written
notice of any Event of Default and of the continuance  thereof,  as hereinbefore
provided,  and, if the Viatel  Trust is not the sole  Holder of the  Convertible
Debentures,  unless also the Holders of not less than 25% in aggregate principal
amount of the Convertible  Debentures then  Outstanding  shall have made written
request upon the Trustee to institute such action or proceedings in its own name
as trustee  hereunder  and shall have  offered to the  Trustee  such  reasonable
indemnity, as it may require,  against the costs, expenses and liabilities to be
incurred  therein or thereby  and the  Trustee  for 60 days after its receipt of
such notice,  request and offer of indemnity  shall have failed to institute any
such  action or  proceeding  and no  direction  inconsistent  with such  written
request  shall  have been  given to the  Trustee  during  such 60 day  period by
Holders of a majority in principal  amount of the  Convertible  Debentures  then
Outstanding; it being understood and intended, and being expressly covenanted by
the taker and Holder of every  Convertible  Debenture with every other taker and
Holder of a Convertible  Debenture and the Trustee,  that no one or more Holders
of Convertible Debentures shall have any right in any manner whatever, by virtue
or by  availing  of any  provision  of this  Indenture  to  affect,  disturb  or
prejudice the rights of any other such Holder of Convertible  Debentures,  or to
obtain or seek to obtain priority over or preference to any other such Holder or
to enforce any right under this Indenture,  except in the manner herein provided
and for the equal,  ratable  and common  benefit of all  Holders of  Convertible
Debentures.

               Section  5.6  UNCONDITIONAL   RIGHT  OF  HOLDERS  OF  CONVERTIBLE
DEBENTURES TO INSTITUTE  CERTAIN  SUITS.  Notwithstanding  any provision in this
Indenture  and any  provision  of any  Convertible  Debenture,  the right of any
Holder of any  Convertible  Debenture to receive payment of the principal of and
(subject to Section 2.9 and Article XI) interest on such  Convertible  Debenture
at the respective rates, in the respective amount on or after the respective due
dates  expressed in such  Convertible  Debenture,  and to institute suit for the
enforcement of any such payment on or after such respective dates,  shall not be
impaired or affected without the consent of such Holder.

               Section 5.7 POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT
WAIVER OF DEFAULT.  Except as provided in Section 2.11 and Section 5.5, no right
or remedy herein  conferred upon or reserved to the Trustee or to the Holders of
Convertible Debentures is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent  permitted by law, be cumulative
and in  addition  to every  other  right and remedy  given  hereunder  or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

               No  delay  or  omission  of  the  Trustee  or of  any  Holder  of
Convertible Debentures to exercise any right or power accruing upon any Event of
Default  occurring and  continuing  as aforesaid  shall impair any such right or
power or shall be  construed  to be a waiver of any such  Event of Default or an
acquiescence  therein; and, subject to Section 5.5, every power and remedy given
by this  Indenture  or by law to the  Trustee or to the  Holders of  Convertible
Debentures  may be exercised  from time to time, and as often as shall be deemed
expedient, by the Trustee or the Holders of Convertible Debentures.

               Section 5.8  CONTROL BY HOLDERS OF  CONVERTIBLE  DEBENTURES.  The
Holders  of  a  majority  in  aggregate  principal  amount  of  the  Convertible
Debentures  at the time  Outstanding  shall  have the right to 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 the Trustee with respect
to the Convertible  Debentures by this  Indenture;  provided that such direction
shall  not be in  conflict  with  any  rule  of law or the  provisions  of  this
Indenture;  and provided  further that the  Trustee,  being  advised by counsel,
shall  have the right to decline to follow  any such  direction  if the  Trustee
shall  determine  that the action or  proceedings  so directed would involve the
Trustee in personal liability or if the Trustee in good faith shall so determine
that the actions or forbearance specified in or pursuant to such direction would
be unduly  prejudicial to the interest of Holders of the Convertible  Debentures
not joining in the giving of said direction.

               Section 5.9 WAIVER OF PAST DEFAULTS. The Holders of not less than
a majority in aggregate  principal  amount of the Convertible  Debentures at the
time Outstanding may on behalf of the Holders of all the Convertible  Debentures
waive any past default hereunder or its consequences, except a default:

               (a) in the payment of the  principal of (or  premium,  if any) or
          any interest on any  Convertible  Debenture as and when the same shall
          become due by the terms of  Convertible  Debentures  otherwise than by
          acceleration  (unless such default has been cured and sums  sufficient
          to pay all matured  installments  of interest  and  principal  and any
          premium  has been  deposited  with the  Trustee  (in  accordance  with
          Section 5.1)), or

               (b) in respect of a covenant  or  provision  hereof  which  under
          Article VIII cannot be modified or amended  without the consent of the
          Holder of each Outstanding Convertible Debenture affected;

provided,  however,  that if the  Convertible  Debentures are held by the Viatel
Trust or the Institutional Trustee of such Trust, such waiver or modification to
such waiver shall not be effective  until the holders of a majority in aggregate
liquidation  amount of Trust Securities of the Viatel Trust shall have consented
to such waiver or modification  to such waiver;  provided  further,  that if the
consent of the Holder of each  Outstanding  Convertible  Debenture  is required,
such waiver shall not be effective until each holder of the Trust  Securities of
the Viatel Trust shall have consented to such waiver.

               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;  but no such waiver  shall  extend to any
subsequent or other  default or Event of Default or impair any right  consequent
thereon.

               Section 5.10 RIGHT OF COURT TO REQUIRE  FILING OF  UNDERTAKING TO
PAY  COSTS. All  parties  to  this  Indenture  agree, and  each  Holder  of  any
Convertible  Debenture,  by his  acceptance  thereof,  shall be  deemed  to have
agreed,  that  any  court  may in its  discretion  require,  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,  suffered  or omitted by it as Trustee,  the
filing by any party  litigant in such suit of an undertaking to pay the costs of

<PAGE>
                                       37

such suit, and that such court may in its discretion  assess  reasonable  costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such  suit,  having  due  regard to the  merits  and good faith of the claims or
defenses made by such party  litigant;  but the provisions of this Section shall
not apply to any suit  instituted by the Trustee,  to any suit instituted by any
Holder of Convertible  Debentures or group of Holders of Convertible  Debentures
holding in the aggregate  more than 10% in principal  amount of the  Outstanding
Convertible  Debentures,  or to any suit  instituted by a Holder of  Convertible
Debentures for the enforcement of the payment of the principal of or interest on
any Convertible Debenture on or after the due date expressed in such Convertible
Debenture or any date fixed for redemption.

               Section 5.11 SUITS FOR ENFORCEMENT.

               In case an Event of Default has occurred, has not been waived and
is continuing,  the Trustee may in its discretion proceed to protect and enforce
the  rights  vested  in  it by  this  Indenture  by  such  appropriate  judicial
proceedings  as the Trustee shall deem most effectual to protect and enforce any
of such  rights,  either  at law or in  equity or in  bankruptcy  or  otherwise,
whether for the specific  enforcement of any covenant or agreement  contained in
this  Indenture or in aid of the exercise of any power granted in this Indenture
or to enforce any other legal or  equitable  right vested in the Trustee by this
Indenture or by law.


                                   ARTICLE VI

                             CONCERNING THE TRUSTEE


               Section 6.1 DUTIES OF THE TRUSTEE. (a) If an Event of Default has
occurred and is  continuing  with  respect to the  Convertible  Debentures,  the
Trustee shall  exercise the rights and powers vested in it by this Indenture and
use the same degree of care and skill in its exercise as a prudent  person would
exercise  or use  under  the  circumstances  in the  conduct  of his or her  own
affairs.

               (b) Except  during the  continuance  of an Event of Default  with
respect to the Convertible Debentures:

               (i)  the  Trustee   need  perform  only  those  duties  that  are
          specifically  set forth in this Indenture and no other duties shall be
          inferred or implied against the Trustee; and

               (ii) 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  furnished to the Trustee and conforming on their face to the
          requirements  of this  Indenture.  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 the  certificates  and opinions to determine  whether or
          not they conform on their face to the requirements of this Indenture.

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

<PAGE>
                                       38

               (i) this paragraph (c) does not limit the effect of paragraph (b)
          of this Section 6.1;

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

               (iii) 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 5.8.

               (d) Every  provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 6.1.

               (e) No provision of this  Indenture  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 in the  exercise of any of its
rights or powers  hereunder,  if it shall have reasonable  grounds for believing
that the  repayment  of such funds or adequate  indemnity  against  such risk or
liability is not reasonably assured to it.

               (f) Money  held by the  Trustee  in trust  hereunder  need not be
segregated  from other funds  except to the extent  required by law. The Trustee
shall be under no liability  for interest on any money  received by it hereunder

               Section  6.2 RIGHTS OF TRUSTEE. Subject  to  Section  6.1 and the
provisions of the Trust Indenture Act:

               (a) The Trustee may conclusively rely on any document (whether in
its  original or facsimile  form)  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,  but the Trustee, in its discretion,  may
make such further inquiry or investigation  into such facts or matters as it may
see fit,  and, if the Trustee  shall  determine to make such further  inquiry or
investigation,  it shall be entitled to examine the books,  records and premises
of the  Company,  personally  or by agent or  attorney  at the sole  cost of the
Company.

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

               (c)  Subject to the  provisions  of Section  6.1(c),  the Trustee
shall not be liable for any action it takes or omits to take in good faith which
it believes to be authorized or within its rights or powers.

               (d) The Trustee may consult with counsel of its selection and the
advice of such  counsel or any  Opinion of  Counsel  shall be full and  complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance  thereon in  accordance  with such
advice or Opinion of Counsel.

                                       39

               (e) The Trustee  shall be under no  obligation to exercise any of
the rights or powers vested in it by this  Indenture at the request or direction
of any of the Holders pursuant to this Indenture, unless such Holders shall have

expenses and  liabilities  which might be incurred by it in compliance with such
request or direction.

               (f) The Trustee may execute any of the trusts or powers hereunder
or perform  any duties  hereunder  either  directly  or by or through  agents or
attorneys  and the  Trustee  shall  not be  responsible  for any  misconduct  or
negligence  on the part of any agent or attorney  appointed  with due care by it
hereunder.

               (g) The rights, privileges,  protections, immunities and benefits
given  to  the  Trustee,   including,   without  limitation,  its  right  to  be
indemnified,  are extended to, and shall be enforceable  by, the Trustee in each
of its  capacities  hereunder,  and to each agent,  custodian  and other  Person
employed by the Trustee with due care to act hereunder.

               Section  6.3  INDIVIDUAL  RIGHTS OF  TRUSTEE. The  Trustee in its
individual or any other  capacity may become the owner or pledgee of Convertible
Debentures and may otherwise  deal with the Company or its  affiliates  with the
same rights it would have if it were not Trustee. Any Paying Agent, Registrar or
co- Registrar may do the same with like rights. However, the Trustee must comply
with Sections 6.10 and 6.11.

               Section   6.4   TRUSTEE'S   DISCLAIMER. The  Trustee   makes   no
representation  as to  the  validity  or  adequacy  of  this  Indenture  or  the
Convertible Debentures, it shall not be accountable for the Company's use of the
proceeds from the  Convertible  Debentures,  it shall not be responsible for any
statement in the registration statement for the Convertible Debentures under the
Securities Act or in the Indenture or the Convertible Debentures (other than its
certificate of authentication).

               Section  6.5  NOTICE  OF  DEFAULTS. If a  default  occurs  and is
continuing with respect to any Convertible  Debentures and if it is known to the
Trustee  through oral or written  notice to a Responsible  Officer,  the Trustee
shall give to each Holder of Convertible Debentures notice of the default within
90 days after such default occurs.  Except in the case of a default described in
Section  5.1(a) or (b),  the Trustee may withhold the notice if and so long as a
committee of its Responsible  Officers in good faith determines that withholding
the notice is in the interest of Holders of Convertible Debentures.

               Section  6.6 REPORTS BY TRUSTEE TO  HOLDERS. Within 60 days after
each May 15, beginning with the May 15 following the date of this Indenture, the
Trustee  shall  mail to each  Holder of  Convertible  Debentures  and each other
person  specified  in TIA Section  313(c) a brief report dated as of such May 15
that  complies  with TIA  Section  313(a) to the extent  required  thereby.  The
Trustee also shall comply with TIA Section 313(b).

               A copy of each  report at the time of its  mailing  to Holders of
Convertible  Debentures  shall be filed with the Commission and each  securities
exchange on which the  Convertible  Debentures  are listed.  The Company  agrees

<PAGE>
                                       40

promptly to notify the Trustee whenever the Convertible Debentures become listed
on any securities exchange and of any delisting thereof.

               Section 6.7 COMPENSATION AND INDEMNITY. The Company agrees:

               (a) to pay to the  Trustee  from  time to time  in  Dollars  such
compensation  as shall be agreed  to in  writing  between  the  Company  and the
Trustee for all services rendered by it hereunder (which  compensation shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust);

               (b) to reimburse the Trustee upon its request for all  reasonable
expenses,  disbursements  and advances with interest thereon incurred or made by
the Trustee in accordance  with any provision of this  Indenture  (including the
reasonable  compensation  and the expenses,  advances with interest  thereon and
disbursements of its agents and counsel), except to the extent any such expense,
disbursement or advance may be attributable to its negligence or bad faith; and

               (c) to fully indemnify the Trustee and any predecessor Trustee in
Dollars for, and to hold it harmless against, any loss, liability, claim, damage
or expense arising out of or in connection with the acceptance or administration
of this trust or the  performance of its duties  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
(including the reasonable compensation and the expenses,  advances with interest
thereon and disbursements of its agents and counsel),  except to the extent that
any such loss,  liability,  claim,  damage or expense may be attributable to its
negligence or bad faith.

               As security for the performance of the obligations of the Company
in this  Section  6.7,  the Trustee  shall have a lien prior to the  Convertible
Debentures  on all money or property  held or collected  by the Trustee,  except
that held in trust to pay the  principal of or interest,  if any, on  particular
Convertible Debentures.

               "Trustee"   for   purposes  of  this  Section  6.7  includes  any
predecessor  Trustee,  provided that the  negligence or bad faith of any Trustee
shall not be attributable to any other Trustee.

               The Company's  payment  obligations  pursuant to this Section 6.7
shall survive the discharge of this Indenture.  When the Trustee incurs expenses
after the occurrence of a default specified in Sections 5.1(d) and 5.1(e),  such
expenses are intended to constitute expenses of administration  under bankruptcy
law.

               Section 6.8 REPLACEMENT OF TRUSTEE. The Trustee may resign at any
time with  respect  to  Convertible  Debentures  by so  notifying  the  Company;
provided,  however,  no such  resignation  shall be effective  until a successor
Trustee has accepted its  appointment  pursuant to this Section 6.8. The Holders
of a majority  in  aggregate  principal  amount of the  Outstanding  Convertible
Debentures  may remove the Trustee at the time  outstanding  by so notifying the
Trustee and the Company. The Company shall remove the Trustee if:

<PAGE>
                                       41

               (1) the Trustee fails to comply with Section 6.10;

               (2) the Trustee is adjudged bankrupt or insolvent;

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

               (4) the Trustee otherwise becomes incapable of acting.

               If the  Trustee  resigns or is removed or if a vacancy  exists in
the  office  of  Trustee  for  any  reason,  with  respect  to  the  Convertible
Debentures,  the Company shall promptly  appoint,  by resolution of its Board of
Directors, a successor Trustee with respect to the Convertible Debentures.

               A successor  Trustee  shall  deliver a written  acceptance of its
appointment  to  the  retiring  Trustee  and  to  the  Company.   Thereupon  the
resignation or removal of the retiring Trustee shall become  effective,  and the
successor  Trustee  shall have all the rights,  powers and duties of the Trustee
under this Indenture with respect to the Convertible  Debentures.  The successor
Trustee  shall  mail a  notice  of its  succession  to  Holders  of  Convertible
Debentures  so  affected.  The  retiring  Trustee  shall  promptly  transfer all
property  held by it as Trustee to the  successor  Trustee,  subject to the lien
provided for in Section 6.7.

               If a successor  Trustee does not take office within 30 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Company or
the  Holders of a majority  in  aggregate  principal  amount of the  Convertible
Debentures  at the time  Outstanding  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  6.10,  any Holder of
Convertible  Debentures may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

               Section  6.9  SUCCESSOR   TRUSTEE  BY  MERGER.   If  the  Trustee
consolidates  with,  merges or converts into, or transfers all or  substantially
all its  corporate  trust  business  or  assets  to,  another  corporation,  the
resulting,  surviving or transferee corporation without any further act shall be
the successor Trustee.

               Section 6.10 ELIGIBILITY;  DISQUALIFICATION. The Trustee shall at
all  times  satisfy  the  requirements  of TIA  Section  310(a)(1)  and  Section
310(a)(5).  The  Trustee  shall have  combined  capital  and surplus of at least
$50,000,000  as  set  forth  in its  most  recent  published  annual  report  of
condition. The Trustee shall comply with TIA Section 310(b).

               Section 6.11  PREFERENTIAL  COLLECTION OF CLAIMS AGAINST COMPANY.

removed shall be subject to TIA Section 311(a) to the extent indicated therein.

               Section 6.12  TRUSTEE'S  APPLICATION  FOR  INSTRUCTIONS  FROM THE
COMPANY.

               Any application by the Trustee for written  instructions from the
Company  may,  at the option of the  Trustee,  set forth in  writing  any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or  after  which such  action  shall be taken or such  omission  shall be
effective.  The Trustee shall not be liable for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or
after the date specified in such application  (which date shall not be less than
five Business Days after the date any officer of the Company  actually  receives
such application,  unless an such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the  effective  date in
the case of an omission),  the Trustee shall have received written  instructions
in response to such application specifying the action to be taken or omitted.

               CONCERNING THE HOLDERS OF CONVERTIBLE DEBENTURES


               Section 7.1  EVIDENCE OF ACTION  TAKEN BY HOLDERS OF  CONVERTIBLE
DEBENTURES.(a) Any request, demand,  authorization,  direction, notice, consent,
waiver or other  action  provided  in this  Indenture  to be given or taken by a
specified   percentage  in  principal  amount  of  the  Holders  of  Convertible
Debentures  may be  embodied  in and  evidenced  by one or more  instruments  or
substantially  similar tenor signed by such  specified  percentage of Holders of
Convertible  Debentures  in person or by agent duly  appointed in writing;  and,
except  as  herein  otherwise  expressly  provided,  such  action  shall  become
effective  when such  instrument  or  instruments  are delivered to the Trustee.
Proof of execution of any  instrument or of a writing  appointing any such agent
shall be sufficient  for any purpose of this  Indenture and (subject to Sections
6.1 and 6.2) conclusive in favor of the Trustee and the Company,  if made in the
manner provided in this Article.

               (b)  The  ownership  of  such  Convertible  Debentures  shall  be
provided by the Security Register.

<PAGE>
                                       43

               Section  7.2  PROOF  OF  EXECUTION  OF  INSTRUMENTS.  Subject  to
Sections 6.1 and 6.2, the execution of any instrument by a Holder of Convertible
Debentures  or his  agent  or  proxy  may be  proved  in  accordance  with  such
reasonable  rules and regulations as may be prescribed by the Trustee or in such
manner as shall be satisfactory to the Trustee.

               Section  7.3  HOLDERS TO BE TREATED AS  OWNERS. The  Company, the
Trustee  and any  agent of the  Company  or the  Trustee  may deem and treat the
person in whose name any  Convertible  Debenture  shall be  registered  upon the
Security Register as the absolute owner of such Convertible  Debenture  (whether
or not such  Convertible  Debenture  shall be overdue  and  notwithstanding  any
notification of ownership or other writing thereon) for the purpose of receiving
payment  of or on account  of the  principal  of and  (subject  to Section  2.9)
interest on such Convertible  Debenture and for all other purposes;  and neither
the Company nor the Trustee nor any agent of the Company or the Trustee shall be
affected by any notice to the contrary.

               Section 7.4  CONVERTIBLE  DEBENTURES  OWNED BY COMPANY DEEMED NOT
OUTSTANDING. In determining  whether  the  Holders  of the  requisite  aggregate
principal  amount of Outstanding  Convertible  Debentures  have concurred in any
direction, consent or waiver under this Indenture,  Convertible Debentures which
are owned by the Company or any other obligor on the Convertible Debentures with
respect to which such  determination  is being made or by any person directly or
indirectly  controlling  or  controlled  by or under  direct or indirect  common
control with the Company or any other obligor on the Convertible Debentures with
respect to which such  determination  is being  made  shall be  disregarded  and
deemed not to be Outstanding for the purpose of any such  determination,  except
that for the purpose of  determining  whether the Trustee  shall be protected in
relying on any such  direction,  consent or waiver only  Convertible  Debentures
which a Responsible  Officer of the Trustee actually knows are so owned shall be
so disregarded.  Convertible Debentures so owned which have been pledged in good
faith  may  be  regarded  as  Outstanding  if  the  pledgee  establishes  to the
satisfaction  of the Trustee the pledgee's  right so to act with respect to such
Convertible  Debentures  and that the  pledgee  is not the  Company or any other
obligor upon the  Convertible  Debentures  or any person  directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any other obligor on the Convertible Debentures.

               Section 7.5 RIGHT OF REVOCATION OF ACTION TAKEN.

               At any time  prior  to (but  not  after)  the  evidencing  to the
Trustee,  as provided in Section 7.1, of the taking of any action by the Holders
of the percentage in aggregate  principal amount of the Convertible  Debentures,
as the case may be,  specified in this Indenture in connection with such action,
any Holder of a Convertible Debenture the serial number of which is shown by the
evidence to be included among the serial numbers of the  Convertible  Debentures
the Holders of which have consented to such action may, by filing written notice
at the  Corporate  Trust  Office and upon proof of holding as  provided  in this
Article,  revoke  such  action so far as concerns  such  Convertible  Debenture.
Except as  aforesaid  any such  action  taken by the  Holder of any  Convertible
Debentures  shall be conclusive and binding upon such Holder and upon all future
Holders  and  owners  of  such  Convertible  Debenture  and of  any  Convertible
Debentures issued in exchange or substitution therefor,  irrespective of whether
or not any  notation  in  regard  thereto  is made  upon  any  such  Convertible
Debenture.  Any action  taken by the  Holders  of the  percentage  in  aggregate

<PAGE>
                                       44

principal amount of the Convertible Debentures, as the case may be, specified in
this Indenture in connection with such action shall be conclusively binding upon
the  Company,  the  Trustee and the  Holders of all the  Convertible  Debentures
affected by such action.

               Section 8.1 SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS OF
CONVERTIBLE  DEBENTURES.  The Company,  when  authorized  by a resolution of its
Board of Directors, and the Trustee for the Convertible Debentures may from time
to time and at any time  enter  into an  indenture  or  indentures  supplemental
hereto (which shall conform to the  provisions of the Trust  Indenture Act as in
force  at the  date of the  execution  thereof),  in form  satisfactory  to such
Trustee, for one or more of the following purposes:

               (a) to  convey,  transfer,  assign,  mortgage  or  pledge  to the
          Trustee as security  for the  Convertible  Debentures  any property or
          assets;

               (b) to evidence  the  succession  of another  corporation  to the
          Company,  or  successive  successions,   and  the  assumption  by  the
          successor corporation of the covenants,  agreements and obligations of
          the Company pursuant to Article IX;

               (c)  to  add  to  the  covenants  of  the  Company  such  further
          covenants,  restrictions,  conditions or provisions for the protection
          of the Holders of Convertible Debentures;

               (d) to  cure  any  ambiguity  or to  correct  or  supplement  any
          provision contained herein or in any supplemental  indenture which may
          be defective or inconsistent with any other provision contained herein
          or in any supplemental  indenture; or to make such other provisions in
          regard to matters or questions  arising under this  Indenture or under
          any  supplemental  indenture  as  the  Board  of  Directors  may  deem
          necessary or desirable  and which shall not  materially  and adversely
          affect the interests of the Holders of the Convertible Debentures; or

               (e) to evidence  and provide for the  acceptance  of  appointment
          hereunder  by a  successor  Trustee  with  respect to the  Convertible
          Debentures.

               The Trustee is hereby  authorized to join with the Company in the
execution of any such supplemental  indenture,  to make any further  appropriate
agreements  and  stipulations  which may be therein  contained and to accept the
conveyance, transfer, assignment, mortgage or pledge of any property thereunder,
but the  Trustee  shall not be  obligated  to enter  into any such  supplemental
indenture  which affects the Trustee's  own rights,  duties or immunities  under
this Indenture or otherwise.

               Any supplemental  indenture  authorized by the provisions of this

provisions of Section 8.2.

CONVERTIBLE  DEBENTURES. With the consent (evidenced as provided in Article VII)
of the Holders of not less than a majority in aggregate  principal amount of the
Convertible  Debentures  at the time  Outstanding  (voting  as one  class),  the
Company,  when  authorized by a resolution  of its Board of  Directors,  and the
Trustee  may,  from time to time and at any time,  enter  into an  indenture  or
indentures  supplemental  hereto (which shall  conform to the  provisions of the
Trust  Indenture  Act as in  force  at the date of  execution  thereof)  for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the  provisions  of this  Indenture  or of any  supplemental  indenture or of
modifying in any manner the rights of the Holders of the Convertible Debentures;
provided,  however, that no such supplemental  indenture shall (a) except to the
extent  permitted by Article XI, extend the Stated  Maturity of any  Convertible
Debenture,  or reduce the principal  amount thereof or any premium  thereon,  or
reduce the rate or extend the time of payment of interest thereon, or reduce any
amount payable on redemption  thereof, or make the principal thereof or interest
thereon  payable  in any  coin or  currency  other  than  that  provided  in the
Convertible  Debentures or in accordance  with the terms  thereof,  or impair or
affect the right of any Holder of  Convertible  Debentures to institute suit for
payment  thereof,   or  adversely  affect  the  right  to  convert   Convertible
Debentures,  or modify the  subordination  provisions  of this  Indenture in any
manner adverse to the Holders of Convertible  Debentures  without the consent of
the  Holders  of each  Convertible  Debenture  so  affected,  or (b)  reduce the
aforesaid  percentage of Convertible  Debentures,  the consent of the Holders of
which is required for any such  supplemental  indenture,  without the consent of
the Holders of each Convertible Debenture so affected.

               Upon  the  request  of the  Company,  accompanied  by a copy of a
resolution  of the Board of Directors  certified  by the  secretary or assistant
secretary of the Company  authorizing  the  execution  of any such  supplemental
indenture,  and upon the filing  with the  Trustee of evidence of the consent of
Holders of  Convertible  Debentures  as aforesaid and other  documents,  if any,
required  by  Section  7.1,  the  Trustee  shall  join with the  Company  in the
execution  of such  supplemental  indenture  or  otherwise,  in which  case such
Trustee may in its  discretion,  but shall not be obligated  to, enter into such
supplemental  indenture  which  affects  the  Trustee's  own  rights,  duties or
immunities under this Indenture or otherwise.

               It shall not be  necessary  for the  consent  of the  Holders  of
Convertible  Debentures under this Section to approve the particular form of any
proposed  supplemental  indenture,  but it shall be  sufficient  if such consent
shall approve the substance thereof.

               Promptly  after the  execution  by the Company and the Trustee of
any  supplemental  indenture  pursuant to the  provisions of this  Section,  the
Company shall give notice thereof to the Holders of then Outstanding Convertible
Debentures,  by mailing a notice thereof by first-class  mail to such Holders at
their addresses as they shall appear on the Security Register,  and in each case
such notice shall set forth in general terms the substance of such  supplemental
indenture.  Any  failure  of the  Company  to give such  notice,  or any  defect
therein,  shall not,  however,  in any way impair or affect the  validity of any
such supplemental indenture.

               Section 8.3 EFFECT OF SUPPLEMENTAL INDENTURE. Every  supplemental
indenture   executed  pursuant  to  this  Article  VIII  shall  conform  to  the
requirements of the Trust Indenture Act. Upon the execution of any  supplemental
indenture  pursuant to the provisions  hereof,  this  Indenture  shall be and be

<PAGE>
                                       46

deemed to be modified and amended in  accordance  therewith  and the  respective
rights,  limitations of rights,  obligations,  duties and immunities  under this
Indenture of the Trustee, the Company and the Holders of Convertible  Debentures
shall thereafter be determined,  exercised and enforced hereunder subject in all
respects to such modifications and amendments,  and all the terms and conditions
of any such  supplemental  indenture  shall be and be deemed to be a part of the
terms and conditions of this Indenture for any and all purposes.

               Section  8.4  DOCUMENTS  TO BE GIVEN  TO  TRUSTEE.  The  Trustee,
subject to the  provisions  of Section 6.1 and 6.2,  shall  receive an Officers'
Certificate  and  an  Opinion  of  Counsel  as  conclusive   evidence  that  any
supplemental  indenture executed pursuant to this Article VIII complies with the
applicable provisions of this Indenture.

               Section 8.5  NOTATION  ON  CONVERTIBLE  DEBENTURES  IN RESPECT OF
SUPPLEMENTAL  INDENTURES.  Convertible  Debentures  authenticated  and delivered
after the execution of any supplemental  indenture pursuant to the provisions of
this Article  VIII may bear,  upon the  direction of the Company,  a notation in
form satisfactory to the Trustee for the Convertible Debentures as to any matter
provided for by such supplemental indenture. If the Company or the Trustee shall
so  determine,  new  Convertible  Debentures  so modified as to conform,  in the
opinion of the Trustee and the Company,  to any  modification  of this Indenture
contained  in any such  supplemental  indenture  may be prepared by the Company,
authenticated  by the Trustee and  delivered  in  exchange  for the  Convertible
Debentures then Outstanding.

                  CONSOLIDATION, MERGER, SALE OR CONVEYANCE


               Section 9.1 COMPANY MAY CONSOLIDATE,  ETC., ON CERTAIN TERMS. The
Company may sell,  transfer,  lease or otherwise convey all or substantially all
of its assets on a  consolidated  basis to any Person,  or  consolidate or merge
with or into,  any other Person,  provided that in any such case, (a) either (i)
the Company shall be the continuing  corporation,  or (ii) if the Company is not
the continuing  corporation,  the successor corporation or Person which acquires
by sale,  transfer,  lease or other conveyance all or  substantially  all of the
assets of the Company,  shall be a corporation  organized  and validly  existing
under the laws of the  United  States of  America  or any state  thereof  or the
District of Columbia and shall expressly  assume the due and punctual payment of
the principal of, premium, if any, and interest  (including  Additional Sums and
Compound  Interest)  on all of the  Convertible  Debentures  according  to their
tenor,  and  the due  and  punctual  performance  and  observance  of all of the
covenants,  agreements  and  conditions (A) of this Indenture to be performed or
observed by the Company by supplemental  indenture  satisfactory to the Trustee,
executed and delivered to the Trustee by such corporation or entity,  and (B) of
the Preferred  Securities  Registration Rights Agreement,  by amendment thereto,
(b)  immediately  after such merger or  consolidation,  or such sale,  transfer,
lease or other conveyance, no Event of Default, and no event which, after notice

Certificate  and an Opinion of Counsel,  each stating that the  requirements  of
this Section have been complied with.

               Section 9.2  SUCCESSOR  CORPORATION  SUBSTITUTED.  In case of any
such consolidation,  merger, sale, transfer, lease or conveyance,  and following
such an assumption  by the successor  corporation,  such  successor  corporation
shall succeed to and be substituted for the Company,  with the same effect as if
it had been named herein,  and (except in the case of a lease) the Company shall
be discharged  from all  obligations  and covenants  under this  Indenture,  the
Convertible   Debentures  and  the  Preferred  Securities   Registration  Rights
Agreement and may be liquidated and dissolved.  Such successor  corporation  may
cause to be signed,  and may issue  either in its own name or in the name of the
Company  any or  all of the  Convertible  Debentures  issuable  hereunder  which
theretofore  shall not have been signed by the Company and be  delivered  to the
Trustee;  and,  upon the  order of such  successor  corporation  instead  of the
Company  and  subject  to all the  terms,  conditions  and  limitations  in this
Indenture  prescribed,  the Trustee shall  authenticate and shall make available

and delivered by the officers of the Company to the Trustee for  authentication,
and any  Convertible  Debentures,  which such successor  corporation  thereafter
shall cause to be signed and delivered to the Trustee for that  purpose.  All of
the  Convertible  Debentures so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Convertible  Debentures theretofore
or thereafter  issued in accordance  with the terms of this  Indenture as though
all of such Convertible  Debentures had been issued at the date of the execution
hereof.

               In case of any such consolidation,  merger, sale, transfer, lease
or conveyance such changes in phraseology and form (but not in substance) may be
made  in  the  Convertible   Debentures  thereafter  to  be  issued  as  may  be
appropriate.

               Section 9.3 OPINION OF COUNSEL TO TRUSTEE.  The Trustee,  subject
to the  provisions  of Section  6.1 and 6.2,  may receive an Opinion of Counsel,

consolidation,  merger, sale, lease or conveyance,  and any such assumption, and
any such liquidation or dissolution,  complies with the applicable provisions of
this Indenture.


                                    ARTICLE X

                   REDEMPTION OF THE CONVERTIBLE DEBENTURES


               Section 10.1 TAX EVENT REDEMPTION.

               If a Tax Event (as defined in the  Declaration)  has occurred and
is continuing and:

               (a) the Company has received a Redemption Tax Opinion (as defined
          in the Declaration); or

               (b) after  receiving a Dissolution Tax Opinion (as defined in the
          Declaration),  the Regular  Trustees  shall have been  informed by tax
          counsel  rendering the Dissolution  Tax Opinion that a  No-Recognition
          Opinion (as defined in the  Declaration)  cannot be  delivered  to the
          Trust,  then,  notwithstanding  Section 10.2(a) but subject to Section
          10.2(b),  the Company  shall have the right upon not less than 30 days
          nor  more  than 60  days  notice  to the  Holders  of the  Convertible
          Debentures to redeem the Convertible Debentures,  in whole or in part,

<PAGE>
                                       48

          for cash within 90 days  following  the  occurrence  of such Tax Event
          (the  "90-Day  Period")  at a  redemption  price  equal to 100% of the
          principal  amount to be redeemed plus any accrued and unpaid  interest
          thereon  (including  Additional  Sums,  if  any,  and,  to the  extent
          permitted by applicable law, Compound Interest, if any) to the date of
          such redemption (the "Redemption Price"), provided that if at the time
          there is  available  to the  Company or the Trust the  opportunity  to
          eliminate,  within the  90-Day  Period,  the Tax Event by taking  some
          ministerial action  ("Ministerial  Action"),  such as filing a form or
          making an election,  or pursuing some other similar reasonable measure
          which has no adverse  effect on the Company,  the Trust or the Holders
          of the Trust Securities  issued by the Trust, the Company shall pursue
          such  Ministerial  Action in lieu of redemption.  The Redemption Price
          shall be paid prior to 12:00 noon,  New York time, on the date of such
          redemption  or such earlier time as the Company  determines,  provided
          that the Company shall  deposit with the Trustee an amount  sufficient
          to pay the Redemption Price prior to the redemption date.

               Section 10.2 OPTIONAL  REDEMPTION BY  COMPANY.(a)  Subject to the
provisions of Section 10.2(b) and to the provisions of this Article X generally,
except as  otherwise  may be  specified  in Section  10.1 or  elsewhere  in this
Indenture,   the  Company  shall  have  the  right  to  redeem  the  Convertible
Debentures,  in whole or in part, from time to time, on or after April 18, 2003.
Any  redemption  pursuant to this  paragraph  will be made upon not less than 30
days nor more than 60 days notice to the Holders of the Convertible  Debentures,
at the following prices (expressed as percentages of the principal amount of the
Convertible  Debentures) (the "Optional Redemption Price") together with accrued
and unpaid  interest  (including  Additional  Sums,  if any,  and, to the extent
permitted by applicable law, Compound Interest,  if any) to, but excluding,  the
redemption  date, if redeemed during the 12-month period  beginning April 18, of
the applicable year set forth below:

                --------------------------------------
                YEAR               REDEMPTION PRICE
                --------------------------------------
                2003                    105.43%
                --------------------------------------
                2004                    104.65%

                --------------------------------------
                2006                    103.10%
                --------------------------------------
                2007                    102.33%
                --------------------------------------
                2008                    101.55%
                --------------------------------------
                2009                    100.78%
                --------------------------------------

and 100% if redeemed on or after April `8, 2010.

               If  Convertible  Debentures are redeemed on any January 15, April
15,  July 15 and October 15,  accrued  and unpaid  interest  shall be payable to
holders of record on the relevant record date.

               The  Company  may not redeem  fewer  than all of the  outstanding
Convertible  Debentures  unless all accrued and unpaid interest has been paid on
all  Convertible   Debentures  for  all  quarterly   interest   payment  periods
terminating on or prior to the date of redemption.

<PAGE>
                                       49

               So long as the  corresponding  Trust  Securities are outstanding,
the proceeds from the redemption of the  Convertible  Debentures will be used to
redeem the Trust  Securities.  If the Convertible  Debentures are only partially
redeemed  pursuant to this Section  10.2,  the  Convertible  Debentures  will be
redeemed pro rata.  The Optional  Redemption  Price,  together with any required
interest  payment,  shall be paid prior to 12:00  noon,  New York  time,  on the
redemption date or at such earlier time as the Company determines  provided that
the  Company  shall  deposit  with the Trustee an amount  sufficient  to pay the
Optional Redemption Price, together with any required interest payment, by 10:00
a.m.,  New  York  time,  on  the  date  such  amounts  are to be  paid.  Partial
redemptions  must be in an  amount  not less  than  $1,000  principal  amount of
Convertible Debentures.

               If  Convertible  Debentures  selected for partial  redemption are
converted in part before termination of the conversion right with respect to the
portion of the Convertible  Debentures so selected, the converted portion of the
Convertible  Debentures  shall be  deemed  (so far as may be) to be the  portion
selected for redemption. Convertible Debentures (or portions thereof) which have
been converted during a selection of Convertible Debentures to be redeemed shall
be treated by the Trustee as Outstanding for the purpose of such  selection.  In
any case where more than one  Convertible  Debenture is  registered  in the same
name, the Trustee in its discretion may treat the aggregate  principal amount so
registered as if it were represented by one Convertible Debenture.

               If any Convertible  Debenture  called for redemption is converted
into Common Stock of the Company,  any money  deposited with the Trustee or with
any Paying Agent or so segregated  and held in trust for the  redemption of such
Convertible  Debenture  shall  (subject  to any  right  of the  Holder  of  such
Convertible  Debenture  or any  Predecessor  Convertible  Debenture  to  receive
interest  as  provided  in the last  paragraph  of  Section  2.9) be paid to the
Company upon the  Company's  request or, if then held by the  Company,  shall be
discharged from such trust.

               (b) If a partial  redemption of the Convertible  Debentures would
result in the delisting of the Convertible  Preferred  Securities  issued by the
Trust from any national  securities  exchange or other organization on which the
Convertible  Preferred  Securities  are then  listed,  the Company  shall not be
permitted to effect such partial  redemption and may only redeem the Convertible
Debentures in whole.

               Section 10.3 NO SINKING FUND. The Convertible  Debentures are not
entitled to the benefit of any sinking fund or subject to any sinking fund.

               Section 10.4 ELECTION TO REDEEM;  NOTICE OF  REDEMPTION;  PARTIAL
REDEMPTIONS.

               The election of the Company to redeem any Convertible  Debentures
shall be evidenced  by, or pursuant to, a resolution  of the Board of Directors.
Notice of redemption  to the Holders of  Convertible  Debentures  required to be
redeemed  or to be  redeemed  as a whole or in part at the option of the Company
shall be given by giving notice of such  redemption as provided in Section 15.4,
at  least  30 days  and not  more  than 60 days  prior  to the  date  fixed  for
redemption to such Holders of Convertible Debentures. Any notice which is mailed
in the manner herein provided shall be  conclusively  presumed to have been duly
given,  whether or not the Holder  receives  the notice.  Neither the failure to

<PAGE>
                                       50

give notice by mail, nor any defect in the notice so mailed to the Holder of any
Convertible  Debenture  designated  for  redemption  as a whole or in part shall
affect the validity of the proceedings for such redemption.

               The notice of  redemption  to each such Holder shall  specify the
date fixed for  redemption,  the  "CUSIP"  number or numbers,  if any,  for such
Convertible  Debentures,  the redemption  price, the Place or Places of Payment,
that payment will be made upon  presentation  and surrender of such  Convertible
Debentures,  that interest accrued to the date fixed for redemption will be paid
as specified in such notice and that on and after said date interest  thereon or
on the portions thereof to be redeemed will cease to accrue, the conversion rate
or price,  the date on which the right to convert the Convertible  Debentures to
be  redeemed  will  terminate  and the place or places  where  such  Convertible
Debentures  may  be  surrendered  for  conversion.  If  less  than  all  of  the
Convertible  Debentures  are to be  redeemed,  the  notice of  redemption  shall
specify the number of the  Convertible  Debentures  to be redeemed.  In case any
Convertible  Debenture is to be redeemed in part, the notice of redemption shall
state the portion of the principal amount thereof to be redeemed and shall state
that on and  after  the  date  fixed  for  redemption,  upon  surrender  of such
Convertible  Debenture, a new Convertible Debenture or Convertible Debentures in
principal amount equal to the unredeemed portion thereof will be issued.

               The notice of redemption of Convertible Debentures to be redeemed
at the option of the Company  shall be given by the Company or, at the Company's
request,  by the Trustee in the name and at the expense of the Company.  If such
notice is to be given by the Trustee,  the Company shall provide  notice of such
redemption  to the  Trustee  at  least  60 days  prior  to the  date  fixed  for
redemption  (unless a shorter notice shall be satisfactory  to the Trustee).  If
such notice is given by the Company,  the Company  shall  provide a copy of such
notice  given to the Holders of such  redemption  to the Trustee at least 2 days
prior to the date  such  notice  is given to such  Holders,  but in any event at
least 30 days and not more than 60 days prior to the date fixed for redemption.

               The  Company or the Trust  shall give  public  notice of any such
redemption  by the issuance of a press  release  through the services of the Dow
Jones Broad Tape, Reuters News Service and Bloomberg News Service.

               Not later than the  redemption  date  specified  in the notice of
redemption  given as provided in this Section,  the Company will have on deposit
with the Trustee or with one or more Paying Agents (or, if the Company is acting
as its own Paying Agent,  set aside,  segregate and hold in trust as provided in
Section 3.3) in funds  available on such date an amount of money  sufficient  to
redeem on the  redemption  date all the  Convertible  Debentures  so called  for
redemption at the appropriate  redemption price,  together with accrued interest
to the  date  fixed  for  redemption.  If  less  than  all  of  the  Outstanding
Convertible  Debentures  are to be redeemed at the election of the Company,  the
Company will deliver to the Trustee at least 60 days prior to the date fixed for
redemption  (unless a shorter  notice shall be  satisfactory  to the Trustee) an
Officers'  Certificate  stating the aggregate  principal  amount of  Convertible
Debentures to be redeemed.

               For all purposes of this Indenture,  unless the context otherwise
requires,  all provisions  relating to the redemption of Convertible  Debentures

<PAGE>
                                       51

shall  relate,  in the  case  of any  Convertible  Debenture  redeemed  or to be
redeemed  only  in  part,  to  the  portion  of the  principal  amount  of  such
Convertible Debenture which has been or is to be redeemed.

               Section  10.5  PAYMENT  OF  CONVERTIBLE   DEBENTURES  CALLED  FOR
REDEMPTION. If  notice of  redemption  has been  given as  above  provided,  the
Convertible  Debentures or portions of Convertible  Debentures specified in such
notice  shall become due and payable on the date and at the place stated in such
notice at the applicable redemption price, together with interest accrued to the
date fixed for redemption,  and on and after said date (unless the Company shall
default in the payment of such Convertible  Debentures at the redemption  price,
together  with  interest  accrued  to said  date)  interest  on the  Convertible
Debentures or portions of Convertible  Debentures so called for redemption shall
cease to accrue,  and,  except as  provided  in Section  6.1,  such  Convertible
Debentures  shall  cease  from and after the date  fixed  for  redemption  to be
entitled  to any  benefit or  security  under this  Indenture,  and the  Holders
thereof shall have no right in respect of such Convertible Debentures except the
right to receive the  redemption  price thereof and unpaid  interest to the date
fixed  for  redemption.  On  presentation  and  surrender  of  such  Convertible
Debentures  at a Place of Payment  specified  in said notice,  said  Convertible
Debentures or the specified  portions  thereof shall be paid and redeemed by the
Company at the  applicable  redemption  price,  together with  interest  accrued
thereon to the date fixed for  redemption;  provided  that,  payment of interest
becoming  due on or prior to the date fixed for  redemption  shall be payable to
the Holders of such  Convertible  Debentures  registered as such on the relevant
record date subject to the terms and provisions of Section 2.9 hereof.

               If any Convertible  Debenture  called for redemption shall not be
so paid upon surrender thereof for redemption,  the principal shall,  until paid
or duly provided  for,  bear interest from the date fixed for  redemption at the
Coupon Rate.

               Upon presentation of any Convertible  Debenture  redeemed in part
only,  the Company  shall execute and the Trustee  shall  authenticate  and make
available for delivery to or on the order of the Holder thereof,  at the expense
of the Company,  a new  Convertible  Debenture  or  Convertible  Debentures,  of
authorized denominations, in principal amount equal to the unredeemed portion of
the Convertible Debenture so presented.

               Section 10.6  EXCLUSION OF CERTAIN  CONVERTIBLE  DEBENTURES  FROM
ELIGIBILITY  FOR  SELECTION  FOR  REDEMPTION.  Convertible  Debentures  shall be
excluded from eligibility for selection for redemption if they are identified by
registration  and  certificate  number  in a  written  statement  signed  by  an
authorized  officer of the Company and delivered to the Trustee at least 30 days
prior to the last date on which notice of redemption may be given as being owned
of record and  beneficially  by, and not pledged or hypothecated  by, either (a)
the Company or (b) an entity  specifically  identified in such written statement
as  directly or  indirectly  controlling  or  controlled  by or under  direct or
indirect common control with the Company.


                                   ARTICLE XI

                      EXTENSION OF INTEREST PAYMENT PERIOD


<PAGE>
                                       52

               Section 11.1 EXTENSION OF INTEREST PAYMENT PERIOD.

               As long as an Event  of  Default  under  Section  5.1(a)  of this
Indenture shall not have occurred and be continuing,  the Company shall have the
right,  at any time and from  time to time  during  the term of the  Convertible
Debentures,  to defer  payments of interest by extending  the  interest  payment
period of such Convertible  Debentures for a period not exceeding 20 consecutive
quarters (the "Extension  Period"),  during which  Extension  Period no interest
shall be due and payable;  provided  that no Extension  Period may extend beyond
the Maturity Date or any earlier  redemption  date.  To the extent  permitted by
applicable law, interest,  the payment of which has been deferred because of the
extension of the interest  payment  period  pursuant to this Section 11.1,  will
bear interest  thereon at the Coupon Rate compounded  quarterly for each quarter
of the Extension Period  ("Compound  Interest").  Each Extension Period, if any,
will end on an Interest  Payment Date. At the end of the Extension  Period,  the
Company shall pay all interest accrued and unpaid on the Convertible Debentures,
including  any  Additional  Sums and, to the extent  permitted by law,  Compound
Interest (together, "Deferred Interest") that shall be payable to the Holders of
the  Convertible  Debentures  in whose  names  the  Convertible  Debentures  are
registered in the Security  Register at the close of business on the record date
next  preceding  such  Interest  Payment  Date.  Before the  termination  of any
Extension Period, the Company may further extend such period, provided that such
period  together  with all previous  and further  extensions  thereof  shall not
exceed 20  consecutive  quarters,  or extend  beyond  the  Maturity  Date or any
earlier  redemption  date. Upon the termination of any Extension Period and upon
the payment of all  Deferred  Interest  then due, the Company may commence a new
Extension Period,  subject to the foregoing  requirements.  No interest shall be
due and payable during an Extension Period,  except at the end thereof,  but the
Company may prepay at any time all or any portion of the interest accrued during
an Extension Period.

               Section 11.2 NOTICE OF EXTENSION.(a) If the Institutional Trustee
is the only  registered  Holder of the  Convertible  Debentures  at the time the
Company  selects an Extension  Period,  the Company shall give written notice to
the Regular Trustees, the Institutional Trustee and the Trustee of its selection
of such Extension Period at least one Business Day before the earlier of (i) the
next succeeding date on which  Distributions on the Trust  Securities  issued by
the Trust are  payable,  or (ii) the date the Regular  Trustees  are required to
give notice of the record date, or the date such  Distributions are payable,  to
the New York Stock Exchange or other applicable self-regulatory  organization or
to holders of the Convertible  Preferred  Securities issued by the Trust, but in
any event at least ten Business Days before such record date.  The Company shall
cause the Trust to give  notice of the  Company's  selection  of such  Extension
Period to holders of the Convertible Preferred Securities.

               (b) If the  Institutional  Trustee is not the only  Holder of the
Convertible  Debentures at the time the Company selects an Extension Period, the
Company shall give the Holders of the Convertible Debentures,  the Institutional
Trustee and the Trustee written notice of its selection of such Extension Period
at least 10 Business Days before the earlier of (i) the next succeeding Interest
Payment  Date or (ii) the date the  Company is  required  to give  notice of the
record or payment date of such interest  payment to the New York Stock  Exchange
or  other  applicable  self-  regulatory  organization  or  to  Holders  of  the
Convertible  Debentures,  but in any event not less than two Business Days prior
to such record date.

               (c) The  quarter  in  which  any  notice  is  given  pursuant  to
paragraphs  (a) or (b) of this  Section  11.2  shall be counted as one of the 20
consecutive  quarters  permitted in the maximum Extension Period permitted under

                                   ARTICLE XII

                      CONVERSION OF CONVERTIBLE DEBENTURES


               Section 12.1  CONVERSION  RIGHTS. Subject to and upon  compliance
with  the  provisions  of this  Article  XII,  the  Convertible  Debentures  are
convertible,  at the option of the Holders,  at any time beginning July 11, 2000
through the close of business on April 14, 2015 (or, in the case of  Convertible
Debentures called for redemption, prior to the close of business on the Business
Day  prior  to  the   corresponding   redemption   date)  into  fully  paid  and
nonassessable  shares of Common  Stock of the  Company at an initial  conversion
rate of 1.048  shares  of  Common  Stock  for each $50 in  principal  amount  of
Convertible  Debentures (equivalent to a conversion price of $47.71 per share of
Common  Stock (the  "Conversion  Price")),  subject to  adjustment  and reset as
described in this Article XII. A Holder of  Convertible  Debentures  may convert
any portion of the  principal  amount of the  Convertible  Debentures  into that
number  of fully  paid and  nonassessable  shares of Common  Stock  obtained  by
dividing the principal  amount of the Convertible  Debentures to be converted by
such Conversion Price. All calculations  under this Article XII shall be made to
the nearest cent or to the nearest 1/100th of a share, as the case may be.

               Section 12.2 CONVERSION PROCEDURES.

               (a) In order  to  convert  all or a  portion  of the  Convertible
Debentures,  the  Holder  thereof  shall  deliver  to the  Conversion  Agent  an
irrevocable notice of conversion (the "Notice of Conversion")  setting forth the
principal  amount of Convertible  Debentures to be converted,  together with the
name or names,  if other than the  Holder,  in which the shares of Common  Stock
should be  issued  upon  conversion  and,  if such  Convertible  Debentures  are
definitive  Convertible  Debentures,  surrender  to  the  Conversion  Agent  the
Convertible Debentures to be converted, duly endorsed or assigned to the Company
or in blank.  In addition,  a holder of  Convertible  Preferred  Securities  may
exercise its right under the Declaration to convert such  Convertible  Preferred
Securities  into  Common  Stock  by  delivering  to  the  Conversion   Agent  an
irrevocable Notice of Conversion setting forth the information called for by the
preceding  sentence and  directing  the  Conversion  Agent (i) to exchange  such
Convertible Preferred Security for a portion of the Convertible  Debentures held
by the  Trust  (at an  exchange  rate of $50  principal  amount  of  Convertible
Debentures  for each  Convertible  Preferred  Security) and (ii) to  immediately
convert such Convertible Debentures, on behalf of such holder, into Common Stock
of the Company pursuant to this Article XII and, if such  Convertible  Preferred
Securities  are in definitive  form,  surrendering  such  Convertible  Preferred
Securities, duly endorsed or assigned to the Company or in blank. So long as any
Convertible  Preferred  Securities are outstanding,  the Trust shall not convert
any Convertible  Debentures except pursuant to a Notice of Conversion  delivered
to the Conversion Agent by a holder of Convertible Preferred Securities.

<PAGE>
                                       54

               If a Notice of  Conversion  is  delivered  on or after the record
date and prior to the  subsequent  Interest  Payment  Date,  the Holder  will be
entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of  Convertible  Debentures to be converted  notwithstanding  the
conversion thereof prior to such Interest Payment Date. However, if a redemption
date falls between a record date and the subsequent  Interest  Payment Date, the
Holder will be entitled to receive,  on such Interest Payment Date, the interest
accrued to, but excluding,  the redemption date. Except as otherwise provided in
the first and second sentences of this paragraph, in the case of any Convertible
Debenture  which is converted,  interest whose Stated Maturity is after the date
of  conversion  of such  Convertible  Debenture  shall not be  payable,  and the
Company shall not make nor be required to make any other payment,  adjustment or
allowance  with  respect  to  accrued  but unpaid  interest  on the  Convertible
Debentures  being  converted,  which  shall be deemed  to be paid in full.  Each
conversion shall be deemed to have been effected  immediately prior to the close
of  business  on the day on which the Notice of  Conversion  was  received  (the
"Conversion  Date") by the Conversion  Agent from the Holder or from a holder of
the Convertible  Preferred Securities effecting a conversion thereof pursuant to
its conversion  rights under the Declaration,  as the case may be. The Person or
Persons entitled to receive the Common Stock issuable upon such conversion shall
be treated for all purposes as the record holder or holders of such Common Stock
as of the Conversion Date. As promptly as practicable on or after the Conversion
Date, the Company shall issue and deliver at the office of the Conversion Agent,
unless  otherwise  directed  by  the  Holder  in the  Notice  of  Conversion,  a
certificate  or  certificates  for the  number of full  shares  of Common  Stock
issuable upon such conversion,  together with the cash payment,  if any, in lieu
of any  fraction  of any share to the Person or Persons  entitled to receive the
same. The Conversion  Agent shall deliver such  certificate or  certificates  to
such Person or Persons.

               (b) The Company's delivery upon conversion of the fixed number of
shares of Common Stock into which the  Convertible  Debentures  are  convertible
(together with the cash payment,  if any, in lieu of fractional shares) shall be
deemed to  satisfy  the  Company's  obligation  to pay the  principal  amount at
Maturity of the portion of  Convertible  Debentures  so converted and any unpaid
interest (including Compound Interest) accrued on such Convertible Debentures at
the time of such conversion.

               (c) No  fractional  shares  of Common  Stock  will be issued as a
result  of  conversion,  but in  lieu  thereof,  the  Company  shall  pay to the
Conversion  Agent a cash  adjustment  in an amount equal to the same fraction of
the  Closing  Price  of  such  fractional  interest  on the  date on  which  the
Convertible  Debentures  were  duly  surrendered  to the  Conversion  Agent  for
conversion,  or, if such day is not a Trading  Day, on the next Trading Day, and
the  Conversion  Agent in turn will make such payment,  if any, to the Holder of
the Convertible Debentures or the holder of the Convertible Preferred Securities
so converted.

               (d) In the event of the conversion of any  Convertible  Debenture
in part only, the Company shall execute and the Trustee shall  authenticate  and
make  available  for delivery to or on the order of the Holder  thereof,  at the
expense of the Company, a new Convertible Debenture or Convertible Debentures in
the aggregate principal amount equal to the unconverted portion thereof.

                                       55

               (e) In effecting the  conversion  transactions  described in this
Section  12.2,  the  Conversion  Agent is  acting  as agent  of the  holders  of
Convertible  Preferred  Securities  (in the  exchange of  Convertible  Preferred
Securities  for  Convertible   Debentures)  and  as  agent  of  the  Holders  of
Convertible  Debentures (in the conversion of Convertible Debentures into Common
Stock),  as the case may be. The  Conversion  Agent is hereby  authorized (i) to
exchange  Convertible  Debentures  held by the  Trust  from  time  to  time  for
Convertible  Preferred  Securities  in  connection  with the  conversion of such
Convertible Preferred Securities in accordance with this Article XII and (ii) to
convert all or a portion of the  Convertible  Debentures  into Common  Stock and
thereupon  to  deliver  such  shares  of  Common  Stock in  accordance  with the
provisions  of this  Article  XII and to deliver to the Trust a new  Convertible
Debenture or  Convertible  Debentures  for any resulting  unconverted  principal
amount.

               Section 12.3 CONVERSION PRICE  ADJUSTMENTS.  The Conversion Price
shall be adjusted from time to time as follows:

               (a) In case  the  Company  shall,  while  any of the  Convertible
          Debentures are outstanding,  (i) pay a dividend or make a distribution
          with respect to Common Stock in shares of Common Stock, (ii) subdivide
          outstanding shares of Common Stock,  (iii) combine  outstanding shares
          of  Common  Stock  into a smaller  number  of shares or (iv)  issue by
          reclassification  of its shares of Common  Stock any shares of capital
          stock of the Company,  the  conversion  privilege  and the  Conversion
          Price for the  Convertible  Debentures  shall be  adjusted so that the
          Holder  of  any  Convertible  Debenture  thereafter   surrendered  for
          conversion  shall be  entitled  to  receive  the  number  of shares of
          capital  stock of the  Company  which  such  Holder  would  have owned
          immediately  following such action had such Convertible Debenture been
          converted  immediately  prior thereto.  An adjustment made pursuant to
          this  subsection  (a) shall  become  effective  immediately  after the
          record date in the case of a dividend or other  distribution and shall
          become  effective  immediately  after the effective  date in case of a
          subdivision, combination or reclassification (or immediately after the
          record  date if a record  date  shall have been  established  for such
          event).  If,  as a  result  of an  adjustment  made  pursuant  to this
          subsection  (a), the Holder of any  Convertible  Debenture  thereafter
          surrendered for conversion  shall become entitled to receive shares of
          two or more  classes or series of capital  stock of the  Company,  the
          Board of Directors (whose  determination shall be conclusive and shall
          be  evidenced  by a Board  Resolution  filed with the  Trustee)  shall
          determine  the  allocation  of the adjusted  Conversion  Price for the
          Convertible  Debentures  between  or among  shares of such  classes or
          series of capital stock.

               (b) In case  the  Company  shall,  while  any of the  Convertible
          Debentures are outstanding, issue rights or warrants to all holders of
          its Common Stock  entitling them (for a period expiring within 45 days
          after the record date  mentioned  below) to subscribe  for or purchase
          shares of Common  Stock at a price  per  share  less than the  current
          market  price per share of Common  Stock (as  determined  pursuant  to
          subsection  (g)  below)  on  the  record  date  mentioned  below,  the
          Conversion  Price for the Convertible  Debentures shall be adjusted so
          that the same shall  equal the price  determined  by  multiplying  the
          Conversion Price in effect  immediately  prior to the date of issuance
          of such rights or warrants by a fraction of which the numerator  shall
          be the  number of shares of Common  Stock  outstanding  on the date of
          issuance of such rights or  warrants  plus the number of shares  which

<PAGE>
                                       56

          the aggregate  offering price of the total number of shares so offered
          for  subscription  or purchase  would  purchase at such current market
          price,  and of which the denominator  shall be the number of shares of
          Common  Stock  outstanding  on the date of  issuance of such rights or
          warrants plus the number of additional  shares of Common Stock offered
          for  subscription or purchase.  Such adjustment shall become effective
          immediately   after  the  record   date  for  the   determination   of
          stockholders  entitled  to receive  such  rights or  warrants.  To the
          extent  that no  shares of Common  Stock  are so  delivered  after the
          expiration of such rights or warrants,  the Conversion  Price shall be
          readjusted  to the  Conversion  Price which would then be in effect if
          such date fixed for the  determination  of  stockholders  entitled  to
          receive such rights or warrants  had not been fixed.  For the purposes
          of this  subsection,  the number of shares of Common Stock at any time
          outstanding  shall not  include  shares  held in the  treasury  of the
          Company. In case any rights or warrants referred to in this subsection
          in respect of which an  adjustment  shall have been made shall  expire
          unexercised  within 45 days after the same shall have been distributed
          or issued by the Company,  the Conversion Price shall be readjusted at
          the time of such  expiration to the  Conversion  Price that would have
          been in  effect  if no  adjustment  had been  made on  account  of the
          distribution or issuance of such expired rights or warrants.

               (c) Subject to the last sentence of this  subsection (c), in case
          the Company shall, by dividend or otherwise, distribute to all holders
          of its Common Stock evidences of its indebtedness, shares of any class
          or series of capital  stock,  cash or assets or rights or  warrants to
          subscribe for or purchase any of its securities  (excluding any rights
          or  warrants   referred  to  in   subsection   (b),  any  dividend  or
          distribution paid exclusively in cash and any dividend or distribution
          referred to in subsection  (a) of this Section  12.3),  the Conversion
          Price  shall be  reduced  so that  the  same  shall  equal  the  price
          determined by multiplying the Conversion  Price in effect  immediately
          prior  to  the   effectiveness   of  the  Conversion  Price  reduction
          contemplated  by  this  subsection  (c) by a  fraction  of  which  the
          numerator  shall be the current market price per share  (determined as
          provided in subsection  (g)) of the Common Stock on the date fixed for
          the payment of such  distribution (the "Reference Date") less the fair
          market value (as  determined  in good faith by the Board of Directors,
          whose  determination shall be conclusive and evidenced by a resolution
          of the Board of Directors),  on the Reference  Date, of the portion of
          the  evidences  of  indebtedness,  shares of capital  stock,  cash and
          assets so  distributed  or of such  subscription  rights  or  warrants
          applicable to one share of Common Stock and the  denominator  shall be
          such  current  market  price  per  share  of the  Common  Stock,  such
          reduction  to become  effective  immediately  prior to the  opening of
          business on the day following the Reference Date;  provided,  however,
          that in the event the numerator shall be less than one, in lieu of the
          foregoing  adjustment,  adequate  provision shall be made so that each
          Holder of Convertible  Debentures shall have the right to receive upon
          conversion  the amount of such  distribution  such  Holder  would have
          received  had  such  Holder  converted  each   Convertible   Debenture
          immediately  prior to the  Reference  Date.  In the event that no such
          dividend or  distribution  is so paid or made,  the  Conversion  Price
          shall again be adjusted to be the Conversion Price which would then be
          in effect if such dividend or  distribution  had not occurred.  If the
          Board  of   Directors   determines   the  fair  market  value  of  any
          distribution  for purposes of this  subsection (c) by reference to the
          actual or when issued  trading  market for any  securities  comprising

<PAGE>
                                       57

          such  distribution,  it must in doing so  consider  the prices in such
          market over the same period used in computing the current market price
          per share of Common Stock  (determined as provided in subsection (g)).
          For purposes of this subsection (c), any dividend or distribution that
          includes  shares of Common  Stock,  or rights or  warrants of the type
          described in subsection  (b), shall be deemed instead to be a dividend
          or  distribution of the evidences of  indebtedness,  shares of capital
          stock,  cash or assets or rights or warrants other than such shares of
          Common  Stock,  or such rights or warrants  of the type  described  in
          subsection (b) (making any Conversion Price reduction required by this
          subsection (c)), immediately followed by a dividend or distribution of
          such  shares of Common  Stock or such  rights or  warrants of the type
          described  in  subsection  (b) (making any  further  Conversion  Price
          adjustment  required  by  subsection  (a)  or  (b)),  except  (A)  the
          Reference  Date of such  dividend or  distribution  as defined in this
          subsection  (c) shall be  substituted  as (1) "the  record date in the
          case of a dividend  or other  distribution,"  and (2) "the record date
          for the determination of stockholders  entitled to receive such rights
          or warrants"  and (3) "the date fixed for such  determination"  within
          the  meaning of  subsections  (a) and (b) and (B) any shares of Common
          Stock  included in such dividend or  distribution  shall not be deemed
          outstanding for purposes of computing any adjustment of the Conversion
          Price in subsection (b).

               (d) In case the  Company  shall pay or make a  dividend  or other
          distribution  on its Common Stock  exclusively in cash  (excluding any
          quarterly  cash  dividend  on  Common  Stock  to the  extent  that the
          aggregate  cash dividend per share of Common Stock in any quarter does
          not exceed the greater of (i) the amount per share of Common  Stock of
          the next  preceding  quarterly  dividend on Common Stock to the extent
          such preceding quarterly dividend did not require an adjustment of the
          Conversion  Price  pursuant  to this  subsection  (d) (as  adjusted to
          reflect  subdivisions or combinations of Common Stock), and (ii) 3.75%
          of the daily  Closing  Price  per  share  determined  as  provided  in
          subsection   (g),  and  excluding  any  dividend  or  distribution  in
          connection  with the  liquidation,  dissolution  or  winding-up of the
          Company), the Conversion Price shall be reduced so that the same shall
          equal the price  determined by  multiplying  the  Conversion  Price in
          effect  immediately prior to the effectiveness of the Conversion Price
          reduction  contemplated  by this subsection (d) by a fraction of which
          the numerator shall be the current market price per share  (determined
          as provided in  subsection  (g)) of the Common Stock on the date fixed
          for the  payment  of such  distribution  less  the  amount  of cash so
          distributed  (and not excluded as provided  above)  applicable  to one
          share of Common Stock and the denominator shall be such current market
          price  per  share of the  Common  Stock  (determined  as  provided  in
          subsection (g)), such reduction to become effective  immediately prior
          to the opening of business on the day following the date fixed for the
          payment of such distribution; provided, however, that in the event the
          portion of the cash so  distributed  applicable to one share of Common
          Stock is equal to or greater  than the current  market price per share
          (as defined in subsection  (g)) of the Common Stock on the record date
          mentioned  above,  in  lieu  of  the  foregoing  adjustment,  adequate
          provision  shall be made so that each Holder of shares of  Convertible
          Debentures  shall have the right to receive upon conversion the amount
          of cash such Holder would have received had such Holder converted each
          Convertible  Debenture  immediately  prior to the record  date for the
          distribution  of the cash.  If an  adjustment  is  required to be made
          pursuant to this subsection (d) as a result of a distribution  that is

<PAGE>
                                       58

          a quarterly  dividend,  such adjustment shall be based upon the amount
          by which such  distribution  exceeds the amount of the quarterly  cash
          dividend  permitted to be excluded as provided above. If an adjustment
          is required to be made pursuant to this  subsection (d) as a result of
          a distribution that is not a quarterly dividend, such adjustment shall
          be based upon the full amount of the  distribution.  In the event that
          no such dividend or  distribution  is so paid or made,  the Conversion
          Price shall again be adjusted to be the  Conversion  Price which would
          then be in effect if such Record Date had not been fixed.

               (e) In case a tender or  exchange  offer  (other  than an odd-lot
          offer) made by the Company or any Subsidiary of the Company for all or
          any portion of the Company's Common Stock shall expire and such tender
          or  exchange  offer  shall  involve the payment by the Company or such
          subsidiary  of  consideration  per share of Common Stock having a fair
          market value (as  determined  in good faith by the Board of Directors,
          whose  determination shall be conclusive and evidenced by a resolution
          of the Board of  Directors) at the last time (the  "Expiration  Time")
          tenders or exchanges  may be made  pursuant to such tender or exchange
          offer (as it shall have been  amended)  that exceeds the Closing Price
          of the Common Stock on the Trading Day next  succeeding the Expiration
          Time,  the  Conversion  Price  shall be reduced so that the same shall
          equal the price  determined by  multiplying  the  Conversion  Price in
          effect  immediately prior to the effectiveness of the Conversion Price
          reduction  contemplated  by this  subsection (e) by a fraction  (which
          shall not be  greater  than one) of which the  numerator  shall be the
          number of shares of Common Stock  outstanding  (including any tendered
          or exchanged  shares) at the Expiration Time multiplied by the Closing
          Price of the  Common  Stock on the  Trading  Day next  succeeding  the
          Expiration Time and the  denominator  shall be the sum of (i) the fair
          market value (determined as aforesaid) of the aggregate  consideration
          payable to  stockholders  based on the  acceptance  (up to any maximum
          specified in the terms of the tender or exchange  offer) of all shares
          validly  tendered or exchanged and not withdrawn as of the  Expiration
          Time (the shares  deemed so accepted,  up to any such  maximum,  being
          referred  to as the  "Purchased  Shares")  and (ii) the product of the
          number  of  shares of Common  Stock  outstanding  (less any  Purchased
          Shares) at the  Expiration  Time and the  Closing  Price of the Common
          Stock on the Trading Day next  succeeding  the Expiration  Time,  such
          reduction to become retroactively  effective  immediately prior to the
          opening of business on the day following the Expiration Time.

               (f) In case a tender or  exchange  offer  made by a Person  other
          than the  Company  or any  Subsidiary  of the  Company  for all or any
          portion of the Common  Stock shall  expire and such tender or exchange
          offer shall  involve the payment by a Person other than the Company or
          any  Subsidiary  of the Company of  consideration  per share of Common
          Stock having a fair market value (as  determined  in good faith by the
          Board  of  Directors,  whose  determination  shall be  conclusive  and
          evidenced by a resolution of the Board of Directors) at the applicable
          Expiration  Time that exceeds the Closing Price of the Common Stock on
          the Trading Day next  succeeding  the  applicable  Expiration  Time in
          which as of the closing  date of the offer the Board of  Directors  of
          the Company is not recommending rejection of the offer, the Conversion
          Price  shall be  reduced  so that  the  same  shall  equal  the  price
          determined by multiplying the Conversion  Price in effect  immediately
          prior  to  the   effectiveness   of  the  Conversion  Price  reduction
          contemplated  by this subsection (f) by a fraction (which shall not be

<PAGE>
                                       59

          greater than one) of which the numerator shall be the number of shares
          of Common  Stock  outstanding  (including  any  tendered or  exchanged
          shares) at the Expiration  Time multiplied by the Closing Price of the
          Common Stock on the Trading Day next  succeeding the  Expiration  Time
          and the  denominator  shall  be the sum of (i) the fair  market  value
          (determined  as aforesaid) of the aggregate  consideration  payable to
          stockholders  based on the acceptance (up to any maximum  specified in
          the terms of the tender or  exchange  offer) of the  Purchased  Shares
          and,  (ii) the  product  of the  number  of  shares  of  Common  Stock
          outstanding (less any Purchased Shares) at the Expiration Time and the
          Closing  Price of the Common Stock on the Trading Day next  succeeding
          the Expiration Time, such reduction to become retroactively  effective
          immediately  prior to the opening of business on the day following the
          Expiration  Time;  provided,   however,  that  the  reduction  of  the
          Conversion Price contemplated by this subsection (f) will only be made
          if the  tender  offer or  exchange  offer is made for an amount  which
          increases that Person's  ownership of Common Stock to more than 25% of
          the total shares of Common Stock  outstanding  and provided,  further,
          that  the  reduction  of the  Conversion  Price  contemplated  by this
          subsection  (f) will not be made if as of the close of the offer,  the
          offering  documents  with respect to such offer  disclose a plan or an
          intention to cause the Company to engage in a consolidation  or merger
          of the Company or a sale of all or substantially  all of the assets of
          the Company.

               (g) For the purpose of any computation  under subsection (b), (c)
          or (d), the current market price per share of Common Stock on any date
          in  question  shall be deemed to be the  average of the daily  Closing
          Prices for the ten Trading Day period ending on the earlier of the day
          in  question  and,  if  applicable,  the day before the "ex" date with
          respect to the issuance or  distribution  requiring such  computation;
          provided,  however,  that if more than one  event  occurs  that  would
          require  an  adjustment  pursuant  to  subsections  (a)  through  (f),
          inclusive,  the Board of Directors  may make such  adjustments  to the
          Closing  Prices  during  such  ten  Trading  Day  period  as it  deems
          appropriate  to  effectuate  the  intent  of the  adjustments  in this
          Section  12.3,  in which case any such  determination  by the Board of
          Directors  shall  be set  forth  in a Board  Resolution  and  shall be
          conclusive.  For purposes of this  paragraph,  the term "ex" date, (1)
          when used with  respect to any  issuance  or  distribution,  means the
          first date on which the Common  Stock  trades  regular  way on the New
          York Stock  Exchange or on such successor  securities  exchange as the
          Common  Stock may be listed or in the  relevant  market from which the
          Closing  Prices  were  obtained  without  the  right to  receive  such
          issuance or distribution, and (2) when used with respect to any tender
          or  exchange  offer  means the first  date on which the  Common  Stock
          trades regular way on such securities exchange or in such market after
          the Expiration Time of such offer.

               (h) The Company may make such reductions in the Conversion Price,
          in addition to those required by  subsections  (a) through (f), as the
          Board of Directors  considers to be advisable to avoid or diminish any
          income  tax to holders of Common  Stock or rights to  purchase  Common
          Stock  resulting from any dividend or distribution of stock (or rights
          to  acquire  stock) or from any event  treated  as such for income tax
          purposes.  The  Company  from time to time may reduce  the  Conversion
          Price by any  amount  for any period of time if the period is at least
          twenty (20) days. Whenever the Conversion Price is reduced pursuant to
          the preceding sentence, the Company shall mail to Holders of record of

<PAGE>
                                       60

          the Convertible  Debentures a notice of the reduction at least 15 days
          prior to the date the reduced  Conversion Price takes effect, and such
          notice shall state the reduced Conversion Price and the period it will
          be in effect.

               (i) No  adjustment  in the  Conversion  Price  shall be  required
          unless  such  adjustment  would  require an increase or decrease of at
          least  1%  in  the  Conversion  Price;  provided,  however,  that  any
          adjustments which by reason of this subsection (i) are not required to
          be made shall be carried forward and taken into account in determining
          whether any subsequent adjustment shall be required.

               (j) If any action  would  require  adjustment  of the  Conversion
          Price  pursuant to more than one of the  provisions  described  above,
          only one  adjustment  shall be made and such  adjustment  shall be the
          amount of adjustment that has the highest absolute value to the Holder
          of Convertible Debentures.

               (k)  Except  as stated  above,  the  Conversion  Rate will not be
          adjusted  for  the   issuance  of  Common  Stock  or  any   securities
          convertible  into, or exchangeable  for, Common Stock, or carrying the
          right to purchase any of the foregoing.

               Section 12.4 MERGER,  CONSOLIDATION OR SALE OF ASSETS. (a) In the
event that the Company shall be a party to any  transaction  (including  without
limitation  (i) any  recapitalization  or  reclassification  of the Common Stock
(other than a change in par value, or from par value to no par value, or from no
par value to par value,  or as a result of a subdivision  or  combination of the
Common  Stock),  (ii) any  consolidation  of the Company  with, or merger of the
Company into,  any other Person,  any merger of another  Person into the Company
(other than a merger  which does not result in a  reclassification,  conversion,
exchange or cancellation of outstanding  shares of Common Stock of the Company),
(iii) any sale or  transfer  of all or  substantially  all of the  assets of the
Company or (iv) any compulsory  share exchange)  pursuant to which either shares
of Common Stock shall be converted  into the right to receive other  securities,
cash  or  other  property,  or,  in the  case of a sale  or  transfer  of all or
substantially  all of the assets of the  Company,  the  holders of Common  Stock
shall be entitled to receive  other  securities,  cash or other  property,  then
lawful provision shall be made as part of the terms of such transaction  whereby
the Holder of each Convertible  Debenture then outstanding  shall have the right
thereafter to convert such Convertible Debenture only into:

               (i) in the case of any such  transaction that does not constitute
          a Common Stock  Fundamental  Change and subject to funds being legally
          available  for such purpose under  applicable  law at the time of such
          conversion,  the  kind and  amount  of the  securities,  cash or other
          property that would have been receivable  upon such  recapitalization,
          reclassification,  consolidation,  merger,  sale,  transfer  or  share
          exchange by a holder of the number of shares of Common Stock  issuable
          upon conversion of such  Convertible  Debenture  immediately  prior to
          such recapitalization,  reclassification, consolidation, merger, sale,
          transfer or share  exchange,  after giving effect,  in the case of any
          Non-Stock  Fundamental  Change,  to any  adjustment in the  Conversion
          Price in accordance  with clause (i) of subsection (c) of this Section
          12.4; and

               (ii) in the  case of any  such  transaction  that  constitutes  a
          Common Stock Fundamental Change,  common stock of the kind received by

<PAGE>
                                       61

          holders of Common Stock as a result of such Common  Stock  Fundamental
          Change in an amount  determined  in  accordance  with  clause  (ii) of
          subsection (c) of this Section 12.4.

               (b) The  Company or the Person  formed by such  consolidation  or
resulting  from such merger or which  acquired such assets or which acquires the
Company's shares, as the case may be, shall make provision in its certificate or
articles of incorporation or other constituent document to establish such right.
Such  certificate or articles of  incorporation  or other  constituent  document
shall provide for adjustments which, for events subsequent to the effective date
of such certificate or articles of incorporation or other constituent  document,
shall be as nearly equivalent as may be practicable to the adjustments  provided
for in  this  Article  XII.  The  above  provisions  shall  similarly  apply  to
successive transactions of the foregoing type.

               (c)  Notwithstanding  any other provision of this Section 12.4 to
the contrary,  if any Fundamental  Change occurs,  then the Conversion  Price in
effect will be adjusted immediately after such Fundamental Change as follows:

               (i) in the case of a Non-Stock Fundamental Change, the Conversion
          Price  of  the  Convertible   Debentures  immediately  following  such
          Non-Stock  Fundamental Change shall be the lower of (A) the Conversion
          Price  in  effect  immediately  prior  to such  Non-Stock  Fundamental
          Change,  but  after  giving  effect  to any  other  prior  adjustments
          effected pursuant to Section 12.3, and (B) the Applicable Price; and

               (ii) in the  case  of a  Common  Stock  Fundamental  Change,  the
          Conversion Price of the Convertible  Debentures  immediately following
          such Common Stock Fundamental  Change shall be the Conversion Price in
          effect immediately prior to such Common Stock Fundamental  Change, but
          after giving effect to any other prior  adjustments  effected pursuant
          to Section 12.3,  multiplied by a fraction,  the numerator of which is
          the  Purchaser  Stock  Price  and  the  denominator  of  which  is the
          Applicable  Price;  provided,  however,  that in the event of a Common
          Stock  Fundamental  Change  in  which  (A)  100% of the  value  of the
          consideration  received by a holder of Common Stock is common stock of
          the  successor,  acquiror or other third party (and cash, if any, paid
          with  respect  to  any  fractional  interests  in  such  common  stock
          resulting  from such Common Stock  Fundamental  Change) and (B) all of
          the Common  Stock shall have been  exchanged  for,  converted  into or
          acquired for,  common stock of the successor,  acquiror or other third
          party  (and  any cash  with  respect  to  fractional  interests),  the
          Conversion Price of the Convertible  Debentures  immediately following
          such Common Stock Fundamental  Change shall be the Conversion Price in
          effect  immediately  prior to such  Common  Stock  Fundamental  Change
          multiplied  by a fraction,  the  numerator of which is one (1) and the
          denominator  of which is the  number of shares of common  stock of the
          successor,  acquiror or other third party  received by a holder of one
          share of Common  Stock as a result of such  Common  Stock  Fundamental
          Change.

               Section 12.5 NOTICE OF ADJUSTMENTS OF CONVERSION PRICE.  Whenever
the Conversion Price is adjusted as herein provided:

               (a) the Company shall compute the adjusted  Conversion  Price and
          shall prepare a certificate  signed by the Chief Financial  Officer or

<PAGE>
                                       62

          the  Treasurer of the Company  setting  forth the adjusted  Conversion
          Price and  showing  in  reasonable  detail  the facts  upon which such
          adjustment is based,  and such  certificate  shall  forthwith be filed
          with the Trustee and the transfer agent for the Convertible  Preferred
          Securities and the Convertible Debentures; and

               (b) a notice stating the  Conversion  Price has been adjusted and
          setting  forth  the  adjusted   Conversion  Price  shall  as  soon  as
          practicable  be  mailed  by the  Company  to  all  record  holders  of
          Convertible  Preferred  Securities and the  Convertible  Debentures at
          their last  addresses  as they appear upon the  transfer  books of the
          Company and the Trust.

               Section 12.6 PRIOR NOTICE OF CERTAIN EVENTS. In case:

               (a) the  Company  shall (i) declare  any  dividend  (or any other
          distribution)  on its Common Stock,  other than (A) a dividend payable
          in shares of Common Stock or (B) a dividend payable in cash that would
          not require an adjustment  pursuant to Section  12.3(c) or (d) or (ii)
          authorize a tender or exchange  offer that would require an adjustment
          pursuant to Section 12.3(e);

               (b) the Company  shall  authorize  the granting to all holders of
          Common  Stock of rights or warrants to  subscribe  for or purchase any
          shares  of stock of any  class or  series  or of any  other  rights or
          warrants;

               (c)  of  any  reclassification  of  Common  Stock  (other  than a
          subdivision  or  combination  of the  outstanding  Common Stock,  or a
          change in par value, or from par value to no par value, or from no par
          value to par value),  or of any  consolidation  or merger to which the
          Company is a party and for which approval of any  stockholders  of the
          Company  shall  be  required,  or of the  sale or  transfer  of all or
          substantially  all of the assets of the  Company or of any  compulsory
          share  exchange  whereby  the  Common  Stock is  converted  into other
          securities, cash or other property; or

               (d) of the voluntary or involuntary  dissolution,  liquidation or
          winding up of the Company;

then  the  Company  shall  (i)  if  any  Convertible  Preferred  Securities  are
outstanding,  cause to be filed  with the  transfer  agent  for the  Convertible
Preferred  Securities,  and shall cause to be mailed to the holders of record of
the  Convertible  Preferred  Securities,  at their last  addresses as they shall
appear  upon the stock  transfer  books of the Trust or (ii)  shall  cause to be
mailed to all  Holders  at their  last  addresses  as they  shall  appear in the
Security Register,  at least 15 days prior to the applicable record or effective
date hereinafter  specified, a notice stating (A) the date on which a record (if
any) is to be taken for the purpose of such  dividend,  distribution,  rights or
warrants or, if a record is not to be taken, the date as of which the holders of
Common Stock of record to be entitled to such dividend, distribution,  rights or
warrants are to be  determined  or (B) the date on which such  reclassification,
consolidation,  merger, sale, transfer, share exchange, dissolution, liquidation
or winding up is expected to become  effec tive,  and the date as of which it is

notice or any defect therein or in the mailing thereof shall affect the validity
of the corporate action required to be specified in such notice). If at any time
the Trustee shall not be the Conversion  Agent, a copy of such notice shall also
forthwith be filed by the Company with the Trustee.

                                       64

               Section  12.7  CERTAIN  ADDITIONAL  RIGHTS.  In case the  Company
shall,  by dividend or otherwise,  declare or make a distribution  on the Common
Stock referred to in Section  12.3(c) or 12.3(d),  the Holder of the Convertible
Debentures,  upon the conversion  thereof subsequent to the close of business on
the date fixed for the  determination  of stockholders  entitled to receive such
distribution  and prior to the  effectiveness of the Conversion Price adjustment
in respect of such  distribution,  shall also be  entitled  to receive  for each
share of Common Stock into which the Convertible  Debentures are converted,  the
portion  of  the  shares  of  Common  Stock,  rights,  warrants,   evidences  of
indebtedness, shares of capital stock, cash and assets so distributed applicable
to one share of Common Stock;  provided,  however,  that, at the election of the
Company  (whose  election  shall be evidenced  by a  resolution  of the Board of
Directors)  with respect to all Holders so converting,  the Company may, in lieu
of distributing to such Holder any portion of such  distribution  not consisting
of cash or securities of the Company, pay such Holder an amount in cash equal to
the fair  market  value  thereof  (as  determined  in good faith by the Board of
Directors, whose determination shall be conclusive and evidenced by a resolution
of  the  Board  of  Directors).  If any  conversion  of  Convertible  Debentures
described in the immediately preceding sentence occurs prior to the payment date
for a  distribution  to holders of Common Stock which the Holder of  Convertible
Debentures  so  converted  is  entitled  to  receive  in  accordance   with  the
immediately  preceding  sentence,  the Company  may elect  (such  election to be
evidenced by a  resolution  of the Board of  Directors)  to  distribute  to such
Holder a due bill for the shares of Common Stock, rights, warrants, evidences of
indebtedness, shares of capital stock, cash or assets to which such Holder is so
entitled,  provided, that such due bill (a) meets any applicable requirements of
the principal national  securities  exchange or other market on which the Common
Stock is then  traded and (b)  requires  payment or  delivery  of such shares of
Common Stock,  rights,  warrants,  evidences of indebtedness,  shares of capital
stock,  cash or assets no later than the date of payment or delivery  thereof to
holders of shares of Common Stock receiving such distribution.

               Section 12.8 TRUSTEE NOT RESPONSIBLE  FOR DETERMINING  CONVERSION
PRICE OR  ADJUSTMENTS.Neither  the Trustee nor any Conversion Agent shall at any
time be under  any  duty or  responsibility  to any  Holder  of any  Convertible
Debenture to determine  whether any facts exist which may require any adjustment
of the  Conversion  Price,  or with  respect to the nature or extent of any such
adjustment  when  made,  or with  respect to the method  employed.  Neither  the
Trustee  nor any  Conversion  Agent  shall be  accountable  with  respect to the
validity  or value (or the kind or amount)  of any shares of Common  Stock or of
any  securities or property,  which may at any time be issued or delivered  upon
the  conversion of any  Convertible  Debenture;  and neither the Trustee nor any
Conversion  Agent makes any  representation  with respect  thereto.  Neither the
Trustee nor any  Conversion  Agent shall be  responsible  for any failure of the
Company to make any cash payment or to issue,  transfer or deliver any shares of
Common Stock or stock  certificates  or other  securities  or property  upon the
surrender  of any  Convertible  Debenture  for the  purpose of  conversion.  All
Convertible  Debentures  delivered  for  conversion  shall be  delivered  to the
Trustee to be cancelled  by or at the  discretion  of the  Trustee,  which shall
dispose of the same as provided in Section 2.12 of this Indenture.

               Section 12.9  RESERVATION OF SHARES OF COMMON  STOCK.The  Company
shall at all times reserve and keep available,  free from preemptive rights, out
of its authorized but unissued Common Stock or treasury shares,  for the purpose

<PAGE>
                                       65

of effecting the conversion of Convertible Debentures, the full number of shares
of  Common  Stock  of the  Company  then  issuable  upon the  conversion  of all
outstanding Convertible Debentures.

               Section 12.10  PAYMENT  OF  CERTAIN  TAXES  UPON  CONVERSION. The
Company  will pay any and all taxes  that may be payable in respect of the issue
or  delivery  of  shares  of its  Common  Stock  on  conversion  of  Convertible
Debentures  pursuant hereto. The Company shall not, however,  be required to pay
any tax which may be payable in respect of any  transfer  involved  in the issue
and  delivery  of shares of its  Common  Stock in a name  other than that of the
Holder of the Convertible  Debenture or Convertible  Debentures to be converted,
and no such  issue or  delivery  shall  be made  unless  and  until  the  person
requesting such issue has paid to the Company the amount of any such tax, or has
established, to the satisfaction of the Company, that such tax has been paid.

               Section 12.11  NONASSESSABILITY.  The Company  covenants that all
shares  of Common  Stock  which may be issued  upon  conversion  of  Convertible
Debentures  will upon  issue in  accordance  with the  terms  hereof be duly and
validly issued and fully paid and nonassessable.


                                  ARTICLE XIII

                     SUBORDINATION OF CONVERTIBLE DEBENTURES


               Section  13.1  CONVERTIBLE   DEBENTURES   SUBORDINATE  TO  SENIOR
INDEBTEDNESS. The Company covenants and agrees, and each Holder of a Convertible
Debenture,  by the Holder's acceptance  thereof,  likewise covenants and agrees,
that, to the extent and in the manner hereinafter set forth in this Article, the
indebtedness  represented by the  Convertible  Debentures and the payment of the
principal  of  (and  premium,  if  any)  and  interest  on  each  and all of the
Convertible Debentures are hereby expressly made subordinate and junior in right
of  payment  to the prior  payment  in full of all  Senior  Indebtedness  of the
Company,  whether  outstanding  at the  date of  this  Indenture  or  thereafter
incurred.  No provision  of this Article  shall  prevent the  occurrence  of any
default or Event of Default hereunder.

               Section 13.2 PAYMENT OVER OF PROCEEDS  UPON  DISSOLUTION, ETC. In
the  event  of  (i)  any  insolvency,  bankruptcy,  receivership,   liquidation,
reorganization,  readjustment,  composition or other similar proceeding relating
to the Company,  its  creditors or its  property,  (ii) any  proceeding  for the

involuntarily,  whether or not involving  insolvency or bankruptcy  proceedings,

other  marshalling  of assets of the  Company,  all  amounts due upon all Senior
Indebtedness of the Company  (including any interest  thereon accruing after the
commencement  of such  proceedings)  shall  first  be paid in full,  or  payment
thereof  provided for in money in accordance with its terms,  before any payment
is made by the  Company on account of the  principal  (and  premium,  if any) or
interest  on the  Convertible  Debentures;  and any payment by the  Company,  or
distribution of assets of the Company of any kind or character, whether in cash,

payment or distribution,  or by the Holders of the Convertible  Debentures or by
the Trustee  under this  Indenture  if  received by them or it,  directly to the
holders of Senior  Indebtedness  of the Company (pro rata to such holders on the
basis of the respective amounts of Senior  Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to the
trustee  or  trustees  under any  indenture  pursuant  to which any  instruments
evidencing such Senior  Indebtedness  may have been issued,  as their respective
interests may appear,  to the extent  necessary to pay such Senior  Indebtedness
(including  any  interest  thereon  accruing  after  the  commencement  of  such
proceedings)  in  full,  after  giving  effect  to  any  concurrent  payment  or
distribution  to or for the  holders  of such  Senior  Indebtedness,  before any
payment or distribution is made to the Holders of the Convertible  Debentures or
to the Trustee.

               In the event that,  notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities,  prohibited by the  foregoing,  shall be received by the
Trustee  before  all Senior  Indebtedness  of the  Company  is paid in full,  or
provision is made for such payment,  such payment or distribution  shall be held
in trust for the benefit of and shall be paid over or  delivered  to the holders
of such Senior Indebtedness or their  representative or  representatives,  or to
the trustee or trustees  under any indenture  pursuant to which any  instruments
evidencing such Senior  Indebtedness may have been issued,  and their respective
interests  may appear,  as  calculated by the Company,  for  application  to the
payment of all Senior Indebtedness of the Company, as the case may be, remaining
unpaid to the extent  necessary to pay such Senior  Indebtedness in full,  after
giving effect to any concurrent payment or distribution to or for the benefit of
the holders of such Senior Indebtedness.

               For purposes of this Article only,  the words "cash,  property or
securities"  shall not be deemed to  include  shares of stock of the  Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment  which are subordinated
in  right  of  payment  to all  Senior  Indebtedness  which  may at the  time be
outstanding  to  substantially  the same extent as, or to a greater extent than,
the Convertible  Debentures are so subordinated as provided in this Article. The
consolidation  of the Company with,  or the merger of the Company into,  another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and  conditions  set forth in Article IX of this Indenture
shall not be deemed a  dissolution,  winding  up,  liquidation,  reorganization,
readjustment,   composition,   assignment   for  the  benefit  of  creditors  or
marshalling  of assets and  liabilities  of the Company for the purposes of this
Section if the Person formed by such  consolidation or into which the Company is
merged or the Person which  acquires by conveyance  or transfer such  properties
and assets substantially as an entirety, as the case may be, shall, as a part of
such consolidation,  merger,  conveyance or transfer, comply with the conditions
set forth in Article IX of this Indenture.

               Section   13.3  PRIOR   PAYMENT  TO  SENIOR   INDEBTEDNESS   UPON
ACCELERATION  OF  CONVERTIBLE  DEBENTURES. In  the event  that  any  Convertible
Debentures are declared due and payable before their Stated  Maturity,  then and
in such event the  holders of Senior  Indebtedness  shall be entitled to receive
payment  in full of all  amounts  due or to become  due on or in  respect of all
Senior  Indebtedness or provision shall be made for such payment in cash, before
the Holders of the  Convertible  Debentures  are entitled to receive any payment

                                       67

(including  any  payment  which may be payable  by reason of the  payment of any
other  indebtedness  of the  Company  being  subordinated  to the payment of the
Convertible  Debentures)  by the  Company  on account  of the  principal  of (or
premium, if any) or interest on the Convertible  Debentures or on account of the
purchase or other acquisition of Convertible Debentures.

               In the event that,  notwithstanding  the  foregoing,  the Company
shall make any payment to the Trustee or the Holder of any Convertible Debenture
prohibited by the foregoing  provisions of this Section, and if such fact shall,
at or prior to the time of such payment, have been made known to the Trustee or,
as the case may be, such Holder,  then and in such event such  payment  shall be
paid over and delivered forthwith to the Company. The provisions of this Section
shall not apply to any  payment  with  respect  to which  Section  13.2 would be
applicable.

               Section 13.4 NO PAYMENT WHEN SENIOR INDEBTEDNESS  IN  DEFAULT. In
the event and  during the  continuation  of any  default  by the  Company in the
payment of principal,  premium, if any, interest or any other payment due on any
Senior  Indebtedness  of the Company,  as the case may be, beyond any applicable
grace  period with  respect  thereto,  or in the event that the  maturity of any
Senior  Indebtedness of the Company has been  accelerated  because of a default,
then,  in any such case, no payment shall be made by the Company with respect to
the principal (including  redemption  payments,  if any) of, premium, if any, or
interest on the Convertible  Debentures until such default is cured or waived or
ceases  to  exist  or any such  acceleration  or  demand  for  payment  has been
rescinded.

               Section 13.5 PAYMENT  PERMITTED  IN CERTAIN  SITUATIONS.  Nothing
contained in this Article or elsewhere in this  Indenture or in the  Convertible
Debentures shall prevent (a) the Company, at any time except during the pendency
of any dissolution,  winding-up,  liquidation or  reorganization of the Company,
whether voluntary or involuntary or any bankruptcy, insolvency,  receivership or
other  proceedings  of the  Company  referred  to in  Section  13.2 or under the
conditions  described in Section 13.3 or 13.4,  from making payments at any time
of principal of or premium,  if any, or interest on the Convertible  Debentures,
or (b) the  application by the Trustee of any money  deposited with it hereunder
to the  payment of or on account of the  principal  of, or  premium,  if any, or
interest on the  Convertible  Debentures or the retention of such payment by the
Holders,  if, at the time of such  application  by the Trustee,  it did not have
knowledge that such payment would have been prohibited by the provisions of this
Article.

               Section  13.6   SUBROGATION   TO  RIGHTS  OF  HOLDERS  OF  SENIOR
INDEBTEDNESS. Subject  to the payment in full of all Senior  Indebtedness or the
provision for such payment in cash or cash  equivalents or otherwise in a manner
satisfactory to the holders of Senior Indebtedness, the rights of the Holders of
Convertible  Debentures  shall be  subrogated  to the extent of the  payments or
distributions  made to the holders of such Senior  Indebtedness  pursuant to the
provisions of this Article (equally and ratably with the holders of indebtedness
of the Company which by its express terms is subordinated to indebtedness of the
Company to  substantially  the same  extent as the  Convertible  Debentures  are
subordinated  to the  Senior  Indebtedness  and is  entitled  to like  rights of
subrogation) to the rights of the holders of such Senior Indebtedness to receive
payments and  distributions of cash,  property and securities  applicable to the
Senior Indebtedness until the principal of (and premium, if any) and interest on
the  Convertible  Debentures  shall  be  paid  in  full.  For  purposes  of such
subrogation,  no  payments  or  distributions  to  the  holders  of  the  Senior
Indebtedness  of any  cash,  property  or  securities  to which the  Holders  of

<PAGE>
                                       68

Convertible  Debentures  or  the  Trustee  would  be  entitled  except  for  the
provisions of this Article,  and no payments over pursuant to the  provisions of
this  Article to or for the  benefit of the  holders of Senior  Indebtedness  by
Holders of Convertible  Debentures or the Trustee,  shall, as among the Company,
its  creditors  other than  holders of Senior  Indebtedness  and the  Holders of
Convertible Debentures, be deemed to be a payment or distribution by the Company
to or on account of the Senior Indebtedness.

               Section 13.7  PROVISIONS  SOLELY TO DEFINE  RELATIVE  RIGHTS. The
provisions  of this  Article  are and are  intended  solely  for the  purpose of
defining the relative rights of the Holders of Convertible Debentures on the one
hand and the holders of Senior Indebtedness on the other hand. Nothing contained
in this Article or elsewhere in this Indenture or in the Convertible  Debentures
is intended to or shall (a) impair,  as among the Company,  its creditors  other
than holders of Senior  Indebtedness and the Holders of Convertible  Debentures,
the obligation of the Company,  which is absolute and unconditional  (and which,
subject to the rights under this Article of the holders of Senior  Indebtedness,
is intended to rank equally with all other general  obligations of the Company),
to pay to the Holders of  Convertible  Debentures the principal of (and premium,
if any) and interest on the  Convertible  Debentures  as and when the same shall
become  due and  payable  in  accordance  with  their  terms;  or (b) affect the
relative rights against the Company of the Holders of Convertible Debentures and
creditors of the  Company,  as the case may be, other than the holders of Senior
Indebtedness;  or (c)  prevent  the  Trustee  or the  Holder of any  Convertible
Debenture  from  exercising all remedies  otherwise  permitted by applicable law
upon default under this  Indenture,  subject to the rights,  if any,  under this
Article of the holders of Senior  Indebtedness  to receive  cash,  property  and
securities otherwise payable or deliverable to the Trustee or such Holder.

               Section 13.8 TRUSTEE TO EFFECTUATE SUBORDINATION.  Each Holder of
a  Convertible  Debenture by such Holder's  acceptance  thereof  authorizes  and
directs  the  Trustee  on such  Holder's  behalf to take  such  action as may be
necessary  or  appropriate  to  effectuate  the  subordination  provided in this
Article and appoints the Trustee such Holder's  attorney-in-fact for any and all
such purposes.

               Section 13.9 NO WAIVER OF  SUBORDINATION  PROVISIONS. No right of
any present or future holder of any Senior Indebtedness to enforce subordination
as herein provided shall at any time in any way be prejudiced or impaired by any
act or  failure  to act on the part of the  Company  or by any act or failure to
act, in good faith, by any such holder,  or by any  noncompliance by the Company
with the terms,  provisions and covenants of this  Indenture,  regardless of any
knowledge thereof any such holder may have or be otherwise charged with.

               Without  in any way  limiting  the  generality  of the  foregoing
paragraph,  the holders of Senior Indebtedness may, at any time and from time to
time,  without  the  consent of or notice to the  Trustee or the  Holders of the
Convertible  Debentures,  without  incurring  responsibility  to the  Holders of
Convertible  Debentures  and without  impairing or releasing  the  subordination
provided  in  this  Article  or the  obligations  hereunder  of the  Holders  of
Convertible  Debentures to the holders of Senior Indebtedness do any one or more
of the following (a) change the manner,  place or terms of payment or extend the
time of payment of, or renew or alter, Senior Indebtedness or otherwise amend or
supplement in any manner Senior  Indebtedness  or any instrument  evidencing the

<PAGE>
                                       69

same or any agreement under which Senior Indebtedness is outstanding;  (b) sell,
exchange,  release or  otherwise  deal with any property  pledged,  mortgaged or
otherwise  securing  Senior  Indebtedness;  (c) release any Person liable in any
manner for the  collection of Senior  Indebtedness;  and (d) exercise or refrain
from exercising any rights against the Company and any other Person.

               Section  13.10 NOTICE TO TRUSTEE.  The Company  shall give prompt
written notice to a Responsible  Officer of the Trustee of any fact known to the
Company  which would  prohibit the making of any payment to or by the Trustee in
respect  of the  Convertible  Debentures  pursuant  to the  provisions  of  this
Article.  Notwithstanding  the provisions of this Article or any other provision
of this  Indenture,  the  Trustee  shall not be charged  with  knowledge  of the
existence  of any facts which would  prohibit the making of any payment to or by
the Trustee in respect of the Convertible  Debentures pursuant to the provisions
of this  Article,  unless and until a  Responsible  Officer of the Trustee shall
have received  written notice thereof from the Company or a holder or holders of
Senior  Indebtedness or from any trustee therefor;  and, prior to the receipt of
any such written notice,  the Trustee,  subject to the provisions of Section 6.2
of this  Indenture,  shall be  entitled  in all  respects to assume that no such
facts exist; provided,  however, that if the Trustee shall have not received the
notice provided for in this Section at least two Business Days prior to the date
upon  which by the terms  hereof any money may become  payable  for any  purpose
(including,  without limitation, the payment of the principal of (or premium, if
any) or interest on any Convertible Debentures,  then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive  such money and to apply the same to the purposes for which they were
received,  and shall not be affected by any notice to the  contrary  that may be
received by it within two Business Days prior to such date.

               Subject to the provisions of Section 6.2 of this  Indenture,  the
Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing  himself to be a holder of Senior Indebtedness (or a trustee
therefor)  to  establish  that such  notice has been given by a holder of Senior
Indebtedness (or a trustee  therefor).  In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior  Indebtedness  to  participate  in any  payment  or
distribution  pursuant to this  Article,  the Trustee may request such Person to
furnish evidence to the reasonable  satisfaction of the Trustee as to the amount
of Senior  Indebtedness held by such Person,  the extent to which such Person is
entitled to  participate  in such  payment or  distribution  and any other facts
pertinent to the rights of such Person under this Article,  and if such evidence
is not  furnished,  the Trustee  may defer any  payment to such  Person  pending
judicial determination as to the right of such Person to receive such payment.

               Section  13.11  RELIANCE  ON  JUDICIAL  ORDER OR  CERTIFICATE  OF
LIQUIDATING  AGENT. Upon  any  payment or distribution  of assets of the Company
referred to in this Article,  the Trustee,  subject to the provisions of Section
6.2 of this  Indenture,  and the  Holders  of  Convertible  Debentures  shall be
entitled to  conclusively  rely upon any order or decree entered by any court of
competent  jurisdiction  in which  such  insolvency,  bankruptcy,  receivership,
liquidation,  reorganization,   dissolution,  winding  up  or  similar  case  or
proceeding is pending, or a certificate of the trustee in bankruptcy,  receiver,
liquidating trustee, custodian,  assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the  Holders of  Convertible  Debentures,  for the purpose of  ascertaining  the
Persons entitled to participate in such payment or distribution,  the holders of

<PAGE>
                                       70

Senior  Indebtedness and other indebtedness of the Company,  as the case may be,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article.

               Section  13.12  TRUSTEE  NOT  FIDUCIARY  FOR  HOLDERS  OF  SENIOR
INDEBTEDNESS. With  respect to the  holders of Senior Indebtedness,  the Trustee
undertakes to perform or to observe only such of its  covenants and  obligations
as are  specifically  set forth in this  Article,  and no implied  covenants  or
obligations  with  respect to the holders of such Senior  Indebtedness  shall be
read into this  Indenture  against the  Trustee.  Except with respect to Section
13.4,  the Trustee shall not be deemed to owe any fiduciary  duty to the holders
of Senior  Indebtedness and shall not be liable to any such holders or creditors
if it shall in good  faith pay over or  distribute  to  Holders  of  Convertible
Debentures or to the Company or to any other Person cash, property or securities
to which any holders of Senior  Indebtedness shall be entitled by virtue of this
Article or otherwise.

               Section 13.13 RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS;
PRESERVATION OF TRUSTEE'S RIGHTS.  The Trustee  in its individual capacity shall
be  entitled  to all the rights set forth in this  Article  with  respect to any
Senior  Indebtedness  which may at any time be held by it, to the same extent as
any other  holder of Senior  Indebtedness  and nothing in this  Indenture  shall
deprive the Trustee of any of its rights as such holder.

               Nothing  in this  Article  XIII  shall  apply to  claims  of,  or
payments to, the Trustee under or pursuant to Section 6.7 of this Indenture.

               Section 13.14 ARTICLE APPLICABLE TO PAYING AGENTS. In case at any
time any Paying  Agent other than the Trustee  shall have been  appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case  (unless the context  otherwise  requires)  be  construed  as
extending to and including such Paying Agent within its meaning as fully for all
intents  and  purposes  as if such  Paying  Agent were named in this  Article in
addition to or in place of the Trustee;  provided,  however,  that Section 13.13
shall not apply to the  Company or any  Affiliate  of the  Company if it or such
Affiliate acts as Paying Agent.

               Section 13.15 CERTAIN CONVERSIONS DEEMED PAYMENT. For purposes of
this Article only,  (a) the issuance and delivery of junior  securities (or cash
paid in lieu of fractional shares) upon conversion of Convertible  Debentures in
accordance  with  Article  XII shall not be deemed to  constitute  a payment  or
distribution  on  account  of  the  principal  of  or  premium  or  interest  on
Convertible  Debentures  or on account of the purchase or other  acquisition  of
Convertible  Debentures,  and (b) the  payment,  issuance  or  delivery of cash,
property or securities  (other than junior  securities  and cash paid in lieu of
fractional shares) upon conversion of a Convertible Debenture shall be deemed to
constitute  payment on account of the principal of such  Convertible  Debenture.
For the purposes of this Section,  the term "junior securities" means (i) shares
of any stock of any class of the  Company  and (ii)  securities  of the  Company
which are subordinated in right of payment to all Senior  Indebtedness which may
be  outstanding  at the time of  issuance  or  delivery  of such  securities  to
substantially  the same extent as, or to a greater extent than, the  Convertible
Debentures are so subordinated as provided in this Article. Nothing contained in
this Article or elsewhere in this Indenture or in the Convertible  Debentures is
intended to or shall impair, as among the Company, its creditors other than

<PAGE>
                                       71

holders of Senior  Indebtedness and the Holders of Convertible  Debentures,  the
right,  which is absolute and  unconditional,  of the Holder of any  Convertible
Debenture to convert such Convertible Debenture in accordance with Article XII.

Company is filed by the Company  with the  Trustee) to Viatel,  Inc.,  685 Third
Avenue, 24th Floor, New York, New York, 10017,  Attention:  General Counsel. Any
notice, direction, request or demand by the Company or any Holder of Convertible
Debentures  to or upon the  Trustee  shall be deemed  to have been  sufficiently
given or made, for all purposes, if given or made at the Corporate Trust Office.

               Where  this   Indenture   provides   for  notice  to  Holders  of
Convertible  Debentures  of any event such notice  shall be  sufficiently  given
(unless  otherwise  herein  expressly  provided)  if in  writing  and  mailed by
first-class  mail,  postage prepaid to such Holders as their names and addresses
appear in the Convertible  Debenture register within the time prescribed.  Where
this Indenture  provides for notice in any manner,  such notice may be waived in
writing by the Person  entitled to receive such notice,  either  before or after
the event,  and such waiver shall be the  equivalent of such notice.  Waivers of
notice by Holders shall be filed with the Trustee,  but such filing shall not be
a condition  precedent to the validity of any action taken in reliance upon such
waiver.  In any case  where  notice to  Holders  is given by mail,  neither  the
failure to mail such  notice,  nor any  defect in any  notice so  mailed,  shall
affect the  sufficiency  of such  notice,  and any notice which is mailed in the
manner herein provided shall be conclusively presumed to have been duly given.

               In case,  by reason of the  suspension  of or  irregularities  in
regular mail service,  it shall be  impracticable  to mail notice to the Company
and Holders of Convertible  Debentures  when such notice is required to be given
pursuant  to any  provision  of this  Indenture,  then any manner of giving such
notice as shall be reasonably  acceptable to the Trustee shall be deemed to be a
sufficient giving of such notice.

               Section  15.5  OFFICERS'  CERTIFICATES  AND  OPINIONS OF COUNSEL;
STATEMENTS  TO BE  CONTAINED  THEREIN.  Upon any  application  or  demand by the

relating  to the  proposed  action  have been  complied  with and an  Opinion of

precedent,  if any, have been complied with, except that in the case of any such
application  or  demand  as  to  which  the  furnishing  of  such  documents  is
specifically  required  by any  provision  of this  Indenture  relating  to such
particular  application or demand, no additional  certificate or opinion need be
furnished.

               Each  certificate  or opinion  provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this  Indenture  shall  include (a) a statement  that the person
making such  certificate  or opinion has read such covenant or condition and the
definitions herein relating thereto,  (b) a brief statement as to the nature and
scope of the examination or investigation  upon which the statements or opinions
contained in such certificate or opinion are based, (c) a statement that, in the
opinion of such person,  he has made such  examination  or  investigation  as is
necessary to enable him to express an informed opinion as to whether or not such
covenant or condition  has been  complied with and (d) a statement as to whether
or not, in the  opinion of such  person,  such  condition  or covenant  has been
complied  with.  Any  certificate,  statement  or opinion of any  officer of the
Company may be based, insofar as it relates to legal matters, upon a certificate
or opinion of or representations by counsel,  unless such officer knows that the

certificate or opinion or representations with respect to the matters upon which
his  certificate,  statement or opinion may be based as aforesaid are erroneous,
or in the exercise of reasonable  care should know that the same are  erroneous.
Any  certificate,  statement  or opinion of counsel may be based,  insofar as it
relates  to  factual  matters  or  information  with  respect to which is in the
possession  of the  Company,  upon the  certificate,  statement or opinion of or
representations  by an officer or officers of the  Company,  unless such counsel
knows that the certificate, statement or opinion or representations with respect
to the matters upon which his certificate,  statement or opinion may be based as
aforesaid are erroneous,  or in the exercise of reasonable care should know that

Company or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or  representations by an accountant or firm of

case may be,  knows that the  certificate  or opinion  or  representations  with
respect to the  accounting  matters  upon which his  certificate,  statement  or
opinion  may  be  based  as  aforesaid  are  erroneous,  or in the  exercise  of
reasonable  care should know that the same are  erroneous.  Any  certificate  or
opinion of any independent firm of public accountants filed with and directed to
the Trustee shall contain a statement that such firm is independent.

               Section 15.6  PAYMENTS DUE ON  SATURDAYS,  SUNDAYS AND  HOLIDAYS.
Except as otherwise provided in Section 2.5, if the date of Maturity of interest
on or principal of the  Convertible  Debentures or the date fixed for redemption
or repayment of any such Convertible Debenture shall not be a Business Day, then
payment of interest or principal  need not be made on such date, but may be made
on the next  succeeding  Business  Day;  provided  that if such next  succeeding
Business Day falls in the next  succeeding  calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on the date of Maturity or the date fixed for  redemption,
and no interest shall accrue for the period after such date.

               Section 15.7  CONFLICT OF ANY  PROVISION OF INDENTURE  WITH TRUST
INDENTURE ACT. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another  provision  included in this Indenture which
is required by the Trust Indenture Act, such required provision shall control.

               Section  15.8  NEW  YORK  LAW TO  GOVERN. THIS INDENTURE  AND THE
CONVERTIBLE  DEBENTURES SHALL BE DEEMED TO BE CONTRACTS MADE AND TO BE PERFORMED

number  of  counterparts,   each  of  which  shall  be  an  original;  but  such
counterparts shall together constitute but one and the same instrument.

               Viatel, Inc., a Delaware  corporation (the "Company",  which term
includes any successor corporation under the Indenture hereinafter referred to),
for  value  received,  hereby  promises  to pay to,  The  Bank of New  York,  as
Institutional Trustee (the "Institutional Trustee") for Viatel Financing Trust I
or registered assigns, the principal sum of One Hundred Eighty-Five Million Five
Hundred Sixty-Seven Thousand Ten Dollars  ($185,567,010)]1 on April 15, 2015 and
to pay  interest on said  principal  sum from April 12,  2000,  or from the most
recent  interest  payment date to which  interest has been paid or duly provided
for,  quarterly  (subject to deferral as set forth herein) in arrears on January
15,  April 15,  July 15 and  October 15 (each such date,  an  "Interest  Payment
Date") of each year  commencing  July 15, 2000,  at the rate of 7 3/4% per annum
until the principal hereof shall have become due and payable, and on any overdue
principal and premium,  if any, and (without  duplication and to the extent that
payment of such interest is  enforceable  under  applicable  law) on any overdue
installment  of interest at the same rate per annum  compounded  quarterly.  The
amount of interest payable on any Interest Payment Date shall be computed on the
basis of a 360-day year of twelve 30-day months.  The amount of interest payable
for any  period  shorter  than a full  quarterly  period for which  interest  is
computed, will be computed on the basis of the actual number of days elapsed per
30-day  month.  In the event that any date on which  interest is payable on this
Convertible Debenture is not a Business Day, then payment of interest payable on
such date will be made on the next  succeeding  day that is a Business  Day (and
without any  interest  or other  payment in respect of any such  delay),  except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately  preceding  Business Day, in each case with the
same force and  effect as if made on such  date.  The  interest  installment  so
payable,  and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Indenture  (referred to on the reverse  hereof) be paid
to the  person  in  whose  name  this  Convertible  Debenture  (or  one or  more
Predecessor Convertible Debentures,  as defined in said Indenture) is registered
on the record date for such  interest  installment,  which shall be the close of
business on the  fifteenth day prior to such  Interest  Payment  Date.  Any such
interest  installment  not punctually  paid or duly provided for shall forthwith
cease to be payable to the  registered  Holders on such  record  date and may be
paid to the  Person in whose  name this  Convertible  Debenture  (or one or more
Predecessor  Convertible Debentures) is registered at the close of business on a
special record date to be fixed by the Trustee for the payment of such defaulted
interest,  notice  whereof  shall  be  given to the  registered  Holders  of the
Convertible  Debentures not less than 10 days prior to such special record date,
or may be paid at any time in any other lawful manner not inconsistent  with the
requirements of any securities exchange on which the Convertible  Debentures may
be listed, and upon such notice as may be required by such exchange, all as more
fully provided in the Indenture.  The principal of (and premium, if any) and the
interest on this Convertible Debenture shall be payable at the office or agency

States of America  that at the time of payment  is legal  tender for  payment of
public and private  debts;  provided,  however,  that payment of interest may be
made at the option of the Company by check  mailed to the  registered  Holder at
such  address as shall  appear in the  Security  Register.  Notwithstanding  the
foregoing,  so  long  as  the  Holder  of  this  Convertible  Debenture  is  the
Institutional Trustee, the payment of the principal of (and premium, if any) and
interest on this  Convertible  Debenture  will be made at such place and to such
account as may be designated by the Institutional Trustee.

               The indebtedness  evidenced by this Convertible  Debenture is, to
the extent provided in the Indenture, subordinate and junior in right of payment
to the prior payment in full of all Senior  Indebtedness,  and this  Convertible
Debenture is issued  subject to the  provisions  of the  Indenture  with respect
thereto. Each Holder of this Convertible  Debenture,  by accepting the same, (a)
agrees to and shall be bound by such provisions,  (b) authorizes and directs the
Trustee  on his or her  behalf  to  take  such  action  as may be  necessary  or
appropriate to acknowledge or effectuate the  subordination  so provided and (c)
appoints the Trustee his or her  attorney-in-fact for any and all such purposes.
Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of
the  acceptance  of the  subordination  provisions  contained  herein and in the
Indenture  by each holder of Senior  Indebtedness,  whether now  outstanding  or
hereafter  incurred,   and  waives  reliance  by  each  such  holder  upon  said
provisions.

               This  Convertible  Debenture shall not be entitled to any benefit
under the Indenture  hereinafter  referred to, be valid or become obligatory for
any purpose  until the  Certificate  of  Authentication  hereon  shall have been
signed by or on behalf of the Trustee.

               The provisions of this Convertible Debenture are continued on the
reverse side hereof and such  continued  provisions  shall for all purposes have
the same effect as though fully set forth at this place.

               Capitalized  terms  used but not  defined  herein  shall have the
meaning given them in the Indenture.

               This  Convertible  Debenture  is one  of  the 7 3/4%  Convertible
Junior   Subordinated   Debentures  (herein  referred  to  as  the  "Convertible
Debentures"),  all issued or to be issued  under and  pursuant  to an  Indenture
dated as of April 12, 2000, duly executed and delivered  between the Company and
The Bank of New York, as Trustee (the  "Trustee")  (the  "Indenture"),  to which
Indenture and all indentures supplemental thereto reference is hereby made for a
description  of the  rights,  limitations  of  rights,  obligations,  duties and
immunities  thereunder  of the  Trustee,  the  Company  and the  Holders  of the
Convertible  Debentures.  The  Convertible  Debentures  are limited in aggregate
principal amount as specified in the Indenture.

               Because of the occurrence  and  continuation  of a Tax Event,  in
certain circumstances,  this Convertible Debenture may become due and payable at
the  principal  amount  specified on the face hereof  together with any interest
accrued thereon (the  "Redemption  Price").  The Redemption  Price shall be paid
prior to 12:00 noon,  New York City time,  on the date of such  redemption or at
such earlier time as the Company determines. The Company shall have the right to
redeem this  Convertible  Debenture at the option of the Company,  upon not less
than 30 nor more than 60 days notice, without premium or penalty, in whole or in
part at any time on or after April 18, 2003 (an  "Optional  Redemption")  at the
following  prices  (expressed  as  percentages  of the  principal  amount of the
Convertible  Debentures) (the "Optional Redemption Price") together with accrued
and unpaid  interest  (including  Additional  Sums,  if any,  and, to the extent
permitted by applicable law, Compound Interest,  if any) to, but excluding,  the
redemption  date, if redeemed during the 12-month  period  beginning April 18 of
the applicable year set forth below:

and 100% if redeemed on or after April 18, 2010.

               If  Convertible  Debentures are redeemed on any January 15, April
15,  July 15 or October  15,  accrued  and unpaid  interest  shall be payable to
holders of record on the relevant record date.

               So long as the  corresponding  Trust  Securities are outstanding,
the proceeds from the redemption of any of the  Convertible  Debentures  will be
used to redeem Trust Securities.

Company pursuant to an Optional Redemption,  the Convertible  Debentures will be
redeemed pro rata.

               In the event of redemption of this Convertible  Debenture in part
only, a new Convertible  Debenture or Convertible  Debentures for the unredeemed
portion  hereof  will be  issued  in the  name of the  Holder  hereof  upon  the
cancellation hereof.

               In case an Event of Default,  as defined in the Indenture,  shall
have  occurred  and be  continuing,  the  principal  of  all of the  Convertible
Debentures  and the  interest  accrued  thereon may be  declared,  and upon such
declaration shall become,  due and payable,  in the manner,  with the effect and
subject to the conditions provided in the Indenture.

               The Indenture contains provisions  permitting the Company and the
Trustee,  with  the  consent  of the  Holders  of a  majority  of the  aggregate
principal  amount  of  the  Convertible  Debentures  at  the  time  Outstanding,
evidenced  as  provided in the  Indenture,  to execute  supplemental  indentures
adding any  provisions  to or changing in any manner or  eliminating  any of the
provisions of the Indenture or of any supplemental indenture or modifying in any
manner  the  rights of the  Holders  of the  Convertible  Debentures;  provided,
however,  that no such  supplemental  indenture  shall  (i)  extend  the  Stated
Maturity of any Convertible Debenture, or reduce the principal amount thereof or
any  premium  thereon,  or reduce  the rate or  extend  the time of  payment  of
interest  thereon,  or reduce any amount  payable upon  redemption  thereof,  or
impair or affect  the right of any  Holder  to  institute  suit for the  payment
thereof,  without the  consent of the Holder of each  Convertible  Debenture  so
affected, or (ii) reduce the aforesaid percentage of Convertible Debentures, the
Holders of which are  required  to consent to any such  supplemental  indenture,
without  the  consent of the Holder of each  Convertible  Debenture.  It is also
provided in the Indenture  that,  with respect to certain  defaults or Events of
Default  regarding  the  Convertible   Debentures,   prior  to  any  declaration
accelerating  the  maturity  of  such  Convertible  Debentures,  or  after  such
declaration  and before any judgment or decree for the payment of the moneys due
is obtained or entered,  and provided the Company has paid or made provision for
payment of any  unaccelerated  amounts  then due,  the  Holders of a majority in
aggregate principal amount Outstanding of the Convertible Debentures (or, in the
case  of  certain  defaults  or  Events  of  Default,  all  of  the  Convertible
Debentures),  may on behalf of the  Holders  of all the  Convertible  Debentures
waive  any such past  default  or Event of  Default  and its  consequences.  The
preceding sentence shall not, however,  apply to a default in the payment of the
principal  of or  premium,  if  any,  or  interest  on any  of  the  Convertible
Debentures.  Any such  consent  or  waiver  by the  Holder  of this  Convertible
Debenture  (unless revoked as provided in the Indenture) shall be conclusive and
binding  upon  such  Holder  and upon all  future  Holders  and  owners  of this
Convertible  Debenture  and any  Convertible  Debenture  which  may be issued in
exchange or substitution  therefor,  irrespective of whether or not any notation
thereof  is made upon  this  Convertible  Debenture  or such  other  Convertible
Debenture.

               No  reference  herein to the  Indenture  and no provision of this
Convertible  Debenture or of the Indenture  shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of and
premium,  if any,  and  interest on this  Convertible  Debenture at the time and
place and at the rate and in the money herein prescribed.

               As long as an  Event  of  Default  under  Section  5.1(a)  of the
Indenture shall not have occurred and be continuing,  the Company shall have the
right at any time during the term of the Convertible Debentures and from time to
time to extend the interest payment period of such Convertible Debentures for up
to 20 consecutive quarters (an "Extension  Period"),  at the end of which period

                                      A-7
<PAGE>

the  Company  shall pay all  interest  then  accrued and unpaid  (together  with
interest  thereon at the rate  specified for the  Convertible  Debentures to the
extent that  payment of such  interest is  enforceable  under  applicable  law).
Before the  termination  of any such Extension  Period,  the Company may further
extend such Extension Period,  provided that such Extension Period together with
all such further extensions thereof shall not exceed 20 consecutive quarters. At
the termination of any such Extension Period and upon the payment of all accrued
and unpaid  interest  and any  additional  amounts  then due,  the  Company  may
commence a new Extension Period.

               As provided in the Indenture  and subject to certain  limitations
therein set forth, this Convertible  Debenture is transferable by the registered
Holder hereof on the Security  Register of the Company,  upon  surrender of this
Convertible  Debenture for  registration  of transfer at the office or agency of
the  Trustee  in the  City  and  State  of New  York  accompanied  by a  written
instrument or instruments of transfer in form satisfactory to the Company or the
Trustee duly  executed by the  registered  Holder  hereof or his  attorney  duly
authorized in writing,  and thereupon one or more new Convertible  Debentures of
authorized  denominations  and for the same aggregate  principal  amount will be
issued to the designated  transferee or  transferees.  No service charge will be
made for any  such  transfer,  but the  Company  may  require  payment  of a sum
sufficient  to cover any tax or other  governmental  charge  payable in relation
thereto.

               Prior to due  presentment  for  registration  of transfer of this
Convertible  Debenture,  the  Company,  the  Trustee,  any paying  agent and the
Registrar may deem and treat the registered  holder hereof as the absolute owner
hereof  (whether  or  not  this  Convertible  Debenture  shall  be  overdue  and
notwithstanding  any notice of ownership or writing  hereon made by anyone other
than the Registrar) for the purpose of receiving payment of or on account of the
principal hereof and premium,  if any, and interest due hereon and for all other
purposes,  and neither the Company nor the Trustee nor any paying  agent nor any
Registrar shall be affected by any notice to the contrary.

               No recourse  shall be had for the payment of the  principal of or
the interest on this Convertible  Debenture,  or for any claim based hereon,  or
otherwise in respect hereof, or based on or in respect of the Indenture, against
any incorporator,  stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation,  whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise,  all such liability being, by the acceptance
hereof  and as part of the  consideration  for the  issuance  hereof,  expressly
waived and released.

               The  Holder  of  any   Convertible   Debenture   has  the  right,
exercisable  at any time  beginning  July 11, 2000 through the close of business
(New York time) on April 14,  2015 (or, in the case of a  Convertible  Debenture
called for redemption,  prior to the close of business on the Business Day prior
to the  corresponding  redemption date), to convert the principal amount thereof
(or any  portion  thereof  that is an  integral  multiple of $50) into shares of
Common Stock at the initial  conversion rate of 1.048 shares of Common Stock for
each Convertible Debenture (equivalent to a Conversion Price of $47.71 per share
of Common Stock), subject to adjustment under certain circumstances.

                                      A-8

               To convert a  Convertible  Debenture,  a Holder must (a) complete
and sign a conversion  notice  substantially  in the form attached  hereto,  (b)
surrender  the  Convertible   Debenture  to  a  Conversion  Agent,  (c)  furnish
appropriate  endorsements  or transfer  documents if required by the  Conversion
Agent and (d) pay any transfer or similar tax, if required. Upon conversion,  no
adjustment or payment will be made for interest or dividends,  but if any Holder
surrenders a Convertible  Debenture  for  conversion on or after the record date
for the  payment  of an  installment  of  interest  and prior to the  opening of
business  on  the  next  Interest  Payment  Date,  then,   notwithstanding  such
conversion,  the interest  payable on such Interest Payment Date will be paid to
the registered Holder of such Convertible Debenture on such record date. In such
event, such Convertible Debenture, when surrendered for conversion,  need not be
accompanied  by  payment  of an amount  equal to the  interest  payable  on such
Interest Payment Date on the portion so converted. However, if a redemption date
falls between a record date and the subsequent Interest Payment Date, the Holder
will be entitled to receive,  on such redemption  date, the interest accrued to,
but  excluding,  the  redemption  date.  The  number  of  shares  issuable  upon
conversion  of a  Convertible  Debenture is determined by dividing the principal
amount of the Convertible  Debenture converted by the Conversion Price in effect
on the Conversion Date. No fractional  shares will be issued upon conversion but
a cash  adjustment  will be made for any fractional  interest.  The  outstanding
principal amount of any Convertible Debenture shall be reduced by the portion of
the principal amount thereof converted into shares of Common Stock.

               The  Convertible  Debentures are issuable only in registered form
without coupons in denominations of $10 and any integral multiple thereof.2 This
Global Debenture is exchangeable  for Convertible  Debentures in definitive form
only under certain limited circumstances set forth in the Indenture. Convertible
Debentures  so issued are issuable only in  registered  form without  coupons in
denominations  of $10 and any  integral  multiple  thereof.3  As provided in the
Indenture  and subject to certain  limitations  therein  set forth,  Convertible
Debentures are exchangeable for a like aggregate principal amount of Convertible
Debentures of a different  authorized  denomination,  as requested by the Holder
surrendering the same.

               THE INDENTURE AND THE CONVERTIBLE  DEBENTURES  SHALL BE DEEMED TO
BE CONTRACTS MADE AND TO BE PERFORMED ENTIRELY IN THE STATE OF NEW YORK, AND FOR
ALL PURPOSES  SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF
SAID STATE WITHOUT REGARD TO THE CONFLICTS OF LAW RULES OF SAID STATE.

          (a) To the extent not  prohibited by any  applicable law or applicable
interpretation  of the staff of the SEC, the Company  shall use its best efforts
to cause to be filed an Exchange Offer Registration Statement covering the offer
by the  Company to the  Holders to  exchange  all of the  Registrable  Notes for
Exchange Notes and to have such  Registration  Statement  remain effective until
the closing of the Exchange Offer. The Company shall commence the Exchange Offer
promptly  after the Exchange  Offer  Registration  Statement  has been  declared
effective  by the SEC and  use its  best  efforts  to have  the  Exchange  Offer
consummated  not later than 60 days after such effective date. The Company shall
commence the Exchange Offer by mailing the related exchange offer Prospectus and
accompanying  documents  to each  Holder  stating,  in  addition  to such  other
disclosures as are required by applicable law:

          (i)  that  the  Exchange   Offer  is  being  made   pursuant  to  this
     Registration  Rights  Agreement  and that  all  Registrable  Notes  validly
     tendered will be accepted for exchange;

          (ii) the dates of acceptance for exchange  (which shall be a period of
     at least 20  business  days  from the date  such  notice  is  mailed)  (the
     "EXCHANGE DATES");

          (iii) that any Registrable  Note not tendered will remain  outstanding
     and continue to accrue interest,  but will not retain any rights under this
     Registration Rights Agreement;


                                        4

<PAGE>

          (iv)  that  Holders  electing  to have a  Registrable  Note  exchanged
     pursuant  to  the  Exchange  Offer  will  be  required  to  surrender  such
     Registrable Note, together with the enclosed letters of transmittal, to the
     institution  and at the address  (located in the Borough of Manhattan,  The
     City of New York) specified in the notice prior to the close of business on
     the last Exchange Date; and

          (v) that  Holders  will be entitled to withdraw  their  election,  not
     later than the close of business on the last  Exchange  Date, by sending to
     the  institution  and at the address  (located in the Borough of Manhattan,
     The City of New York) specified in the notice a telegram,  telex, facsimile
     transmission or letter setting forth the name of such Holder, the principal
     amount of  Registrable  Notes  delivered for exchange and a statement  that
     such Holder is  withdrawing  his or her  election to have such  Registrable
     Notes exchanged.

          As  soon  as  practicable  after  the  last Exchange Date, the Company
 shall:

          (i) accept for exchange Registrable Notes or portions thereof tendered
     and not validly withdrawn pursuant to the Exchange Offer; and

          (ii)  deliver,   or  cause  to  be  delivered,   to  the  Trustee  for
     cancellation  all  Registrable  Notes or portions  thereof so accepted  for
     exchange  by the  Company  and issue,  and cause the  Trustee  to  promptly
     authenticate  and mail to each Holder,  an Exchange Note equal in principal
     amount  and of like  terms to the  Registrable  Notes  surrendered  by such
     Holder.

The  Company  shall use its best  efforts  to  complete  the  Exchange  Offer as
provided  above and shall comply with the  applicable  requirements  of the 1933
Act, the 1934 Act and other  applicable  laws and regulations in connection with
the Exchange  Offer.  The Exchange Offer shall not be subject to any conditions,
other  than that the  Exchange  Offer  does not  violate  applicable  law or any
applicable  interpretation of the staff of the SEC. The Company shall inform the
Placement  Agents of the names and addresses of the Holders to whom the Exchange
Offer is made,  and the  Placement  Agents  shall  have the  right,  subject  to
applicable  law, to contact such Holders and otherwise  facilitate the tender of
Registrable Notes in the Exchange Offer.

          (b) In the event that (i) the  Company  determines  that the  Exchange
Offer  Registration  provided for in Section 2(a) above is not  available or may
not be consummated  as soon as practicable  after the last Exchange Date because
it would violate  applicable law or the applicable  interpretations of the staff
of the SEC, (ii) the Exchange  Offer is not for any other reason  consummated by
the date that is six months after the Closing  Date or (iii) the Exchange  Offer
has been  completed  and in the  opinion of counsel for the  Placement  Agents a
Registration  Statement must be filed and a Prospectus  must be delivered by the
Placement Agents in connection with any offering or sale of Registrable Notes by
such Placement  Agents, of Registrable Notes that were acquired by the Placement
Agents from the Company, the Company


                                        5

<PAGE>

shall use its best  efforts  to cause to be filed as soon as  practicable  after
such  determination,  date or notice of such  opinion of counsel is given to the
Company,  as the case may be, a Shelf Registration  Statement  providing for the
sale by the  Holders  of all of the  Registrable  Notes and to have  such  Shelf
Registration  Statement declared effective by the SEC. The Company agrees to use
its best efforts to keep the Shelf Registration Statement continuously effective
until the expiration of the period referred to in Rule 144(k) under the 1933 Act
with  respect  to  all  Registrable  Notes  covered  by the  Shelf  Registration
Statement,  or  such  shorter  period  that  will  terminate  when  all  of  the
Registrable  Notes covered by the Shelf  Registration  Statement  have been sold
pursuant to the Shelf  Registration  Statement  or as would be  permitted by the
current rules and regulations. The Company further agrees to supplement or amend
the Shelf  Registration  Statement  if  required  by the rules,  regulations  or
instructions  applicable to the  registration  form used by the Company for such
Shelf Registration Statement or by the 1933 Act or by any other applicable rules
and regulations  thereunder for shelf registration or if reasonably requested by
a Holder with respect to  information  relating to such  Holder,  and to use its
best  efforts to cause any such  amendment  to become  effective  and such Shelf
Registration Statement to become usable as soon as thereafter  practicable.  The
Company agrees to furnish to the Holders of Registrable Notes copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

          (c) The Company shall pay all Registration Expenses in connection with
the registration pursuant to Section 2(a) or Section 2(b). Each Holder shall pay
all underwriting  discounts and commissions and transfer taxes, if any, relating
to the sale or  disposition of such Holder's  Registrable  Notes pursuant to the
Shelf Registration Statement.

          (d) An Exchange Offer Registration  Statement pursuant to Section 2(a)
hereof or a Shelf  Registration  Statement  pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared  effective by
the SEC unless such action by the SEC is no longer required;  PROVIDED, HOWEVER,
that,  if, after it has been  declared  effective,  the offering of  Registrable
Notes pursuant to a Shelf Registration  Statement is interfered with by any stop
order,  injunction  or  other  order  or  requirement  of the  SEC or any  other
governmental agency or court, such Registration  Statement will be deemed not to
have become effective during the period of such interference  until the offering
of Registrable Notes pursuant to such Registration Statement may legally resume.
In the  event  that  the  Exchange  Offer  is not  consummated  and,  if a Shelf
Registration  Statement is required hereby, the Shelf Registration  Statement is
not  declared or  permitted  to go effective on or prior to the date that is six
months after the Closing Date, the annual  interest rate borne by the Notes will
increase by 0.5% per annum,  until the date the Exchange Offer is consummated or
a Shelf Registration Statement is declared effective.

          (e) Without  limiting the remedies  available to the Placement  Agents
and the  Holders,  the Company  acknowledges  that any failure by the Company to
comply with its  obligations  under  Section  2(a) and  Section  2(b) hereof may
result in material irreparable injury to the Placement Agents or the Holders for
which  there is no  adequate  remedy  at law,  that it will not be  possible  to
measure damages for such injuries precisely  and that, in  the event of any such

                                        6

<PAGE>

failure,  the  Placement  Agents or any Holder may obtain  such relief as may be
required to specifically  enforce the Company's  obligations  under Section 2(a)
and Section 2(b) hereof.

          3. REGISTRATION PROCEDURES.

          In connection  with the obligations of the Company with respect to the
Registration  Statements  pursuant to Section 2(a) and Section 2(b) hereof,  the
Company shall as expeditiously as possible:

     in accordance with Section 2 hereof;

          (b) prepare and file with the SEC such  amendments and  post-effective
     amendments to each Registration  Statement as may be necessary to keep such
     Registration  Statement  effective for the applicable period and cause each
     Prospectus to be supplemented by any required prospectus supplement and, as
     so  supplemented,  to be filed  pursuant to Rule 424 under the 1933 Act; to
     keep each Prospectus current during the period described under Section 4(3)
     and Rule 174  under  the 1933 Act that is  applicable  to  transactions  by
     brokers or dealers with respect to the Registrable Notes or Exchange Notes;

          (c) in the case of a Shelf  Registration,  furnish  to each  Holder of
     Registrable  Notes, to counsel for the Placement Agents, to counsel for the

     Notes, if any, without charge, as many copies of each Prospectus, including
     each preliminary  Prospectus,  and any amendment or supplement  thereto and
     such other documents as such Holder or Underwriter may reasonably  request,
     in  order  to  facilitate  the  public  sale or  other  disposition  of the
     Registrable  Notes;  and the Company consents to the use of such Prospectus
     and any amendment or supplement  thereto in accordance  with applicable law
     by  each  of  the  selling  Holders  of  Registrable  Notes  and  any  such
     Underwriters  in connection  with the offering and sale of the  Registrable
     Notes  covered by and in the manner  described  in such  Prospectus  or any
     amendment or supplement thereto in accordance with applicable law;

          (d) use its  reasonable  best  efforts  to  register  or  qualify  the
     Registrable  Notes under all applicable state securities or "blue sky" laws
     of such  jurisdictions  as any  Holder of  Registrable  Notes  covered by a
     Registration  Statement shall reasonably request in writing by the time the
     applicable Registration Statement is declared effective by the SEC,

                                        7

<PAGE>

     to cooperate with  such  Holders  in  connection  with any filings required
     to be made with the National Association of Securities Dealers, Inc. and do
     any and all other  acts and things  which may be  reasonably  necessary  or
     advisable to enable such Holder to consummate the  disposition in each such
     jurisdiction  of such  Registrable  Notes owned by such  Holder;  PROVIDED,
     HOWEVER, that the Company shall not be required to (i) qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction where it would
     not otherwise be required to qualify but for this Section  3(d),  (ii) file
     any  general  consent to service  of  process  or (iii)  subject  itself to

     such  advice  in  writing  (i) when a  Registration  Statement  has  become
     effective and when any post-effective  amendment thereto has been filed and

     securities  authority of any stop order  suspending the  effectiveness of a
     Registration  Statement  or the  initiation  of any  proceedings  for  that
     purpose,  (iv) if, between the effective  date of a Registration  Statement
     and the  closing of any sale of  Registrable  Notes  covered  thereby,  the
     representations and warranties of the Company contained in any underwriting
     agreement,  securities sales agreement or other similar agreement,  if any,
     relating  to the  offering  cease to be true and  correct  in all  material
     respects or if the Company  receives any  notification  with respect to the
     suspension of the  qualification  of the Registrable  Notes for sale in any
     jurisdiction  or the initiation of any proceeding for such purpose,  (v) of
     the happening of any event during the period a Shelf Registration Statement
     is effective which makes any statement made in such Registration  Statement
     or the related  Prospectus untrue in any material respect or which requires
     the making of any changes in such  Registration  Statement or Prospectus in
     order to make the statements therein not misleading in any material respect

     requested);

          (h) in the case of a Shelf  Registration,  cooperate  with the selling
     Holders of  Registrable  Notes to  facilitate  the timely  preparation  and
     delivery of certificates  representing Registrable Notes to be sold and not
     bearing any restrictive  legends and enable such Registrable Notes to be in
     such  denominations  (consistent  with the provisions of the Indenture) and
     registered in such names as the selling  Holders may reasonably  request at
     least two  business  days prior to the  closing of any sale of  Registrable
     Notes;

          (i) in the case of a Shelf  Registration,  upon the  occurrence of any
     event  contemplated  by Section  3(e)(v)  hereof,  use its best  efforts to

     Registration   Statement  or  the  related   Prospectus   or  any  document
     incorporated  therein by reference or file any other  required  document so
     that, as thereafter  delivered to the purchasers of the Registrable  Notes,
     such Prospectus will not contain any untrue statement of a material fact or
     omit to state a material fact 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 the  Prospectus
     as promptly as practicable  after the occurrence of such an event,  and the
     Holders hereby agree to suspend use of the Prospectus until the Company has
     amended or  supplemented  the  Prospectus to correct such  misstatement  or
     omission;

          (j) a  reasonable  time  prior  to  the  filing  of  any  Registration

     the  Exchange  Act)  which  is to  be  incorporated  by  reference  into  a
     Registration  Statement or a Prospectus,  of which the Placement Agents and
     their  counsel  (and, in the case of a Shelf  Registration  Statement,  the
     Holders  and their  counsel)  shall not have  previously  been  advised and
     furnished a copy or to which the Placement Agents or their counsel (and, in
     the case of a Shelf Registration  Statement,  the Holders or their counsel)
     shall reasonably object;

          (k) obtain a CUSIP and a Common Code number for all Exchange  Notes or

     reasonable manner, all financial and other records, pertinent documents and
     properties of the Company, and cause the respective officers, directors and
     employees of the Company to supply all information  reasonably requested by
     any such representative,  Underwriter, attorney or accountant in connection

     efforts to enter  into such  customary  agreements  and take all such other
     actions in connection  therewith  (including those requested by the Holders
     of a majority in principal  amount of the Registrable  Notes being sold) in
     order to expedite or facilitate the disposition of such  Registrable  Notes
     including,  but  not  limited  to,  an  Underwritten  Offering  and in such
     connection,  (i) to the  extent  possible,  make such  representations  and
     warranties to the Holders and any  Underwriters of such  Registrable  Notes
     with respect to the business of the Company and its subsidiaries, the Shelf
     Registration Statement,  Prospectus and documents incorporated by reference
     therein or deemed  incorporated by reference therein, if any, in each case,

     of the  Company,  or of any  business  acquired  by the  Company  for which
     financial  statements and financial data are or are required to be included
     in the Shelf Registration  Statement)  addressed to each selling Holder and

     in connection with underwritten offerings,  and (iv) deliver such documents

     Underwriters,   and  which  are   customarily   delivered  in  underwritten
     offerings,  to evidence the continued validity of the  representations  and
     warranties of the Company made pursuant to clause (i) above and to evidence
     compliance  with any  customary  conditions  contained  in an  underwriting
     agreement.

          In the case of a Shelf Registration Statement, the Company may require
each  Holder of  Registrable  Notes to furnish to the Company  such  information
regarding  the  Holder  and the  proposed  distribution  by such  Holder of such
Registrable  Notes as the  Company may from time to time  reasonably  request in
writing.  No Holder of Registrable  Notes may include its  Registrable  Notes in
such Shelf  Registration  Statement  unless and until such Holder furnishes such
information to the Company.  Each Holder including  Registrable Notes in a Shelf
Registration  shall agree to furnish  promptly  to the  Company any  information
regarding  such  Holder and the  proposed  distribution  by such  Holder of such
Registrable Notes required to make any information  previously  furnished to the
Company by such Holder not materially misleading.

          In the case of a Shelf  Registration  Statement,  each  Holder  agrees
that,  upon receipt of any notice from the Company of the happening of any event
of the kind  described in Section  3(e)(v)  hereof,  such Holder will  forthwith
discontinue  disposition of Registrable  Notes pursuant to a Shelf  Registration
Statement  until such  Holder's  receipt of the  copies of the  supplemented  or
amended Prospectus  contemplated by Section 3(i) hereof,  and, if so directed by
the Company, such Holder will deliver to the Company (at its expense) all copies
in its  possession,  other than  permanent  file  copies  then in such  Holder's
possession,  of the Prospectus  covering such  Registrable  Notes current at the
time of receipt of such  notice.  If the  Company  shall give any such notice to
suspend the  disposition of Registrable  Notes pursuant to a Shelf  Registration
Statement,  the Company  shall extend the period  during which the  Registration
Statement shall be maintained effective pursuant to this Agreement by the number
of days  during the  period  from and  including  the date of the giving of such
notice to and including the date when the Holders shall have received  copies of
the supplemented or amended  Prospectus  necessary to resume such  dispositions.
There may not be more than two such  suspensions  during  any 365 day period and
any such suspensions may not exceed 30 days for each suspension.

          The  Holders of  Registrable  Notes  covered  by a Shelf  Registration
Statement who desire to do so may sell such Registrable Notes in an Underwritten
Offering; PROVIDED THAT the Company shall be required to use its reasonable best
efforts to effect an  underwritten  offering only upon the request of Holders of
at least 25% in aggregate  principal amount of the Registrable Notes outstanding
at the time such request is delivered to the Company. In any such

                                        11

<PAGE>

Underwritten  Offering,  the investment banker or investment bankers and manager
or managers  (the  "UNDERWRITERS")  that will  administer  the offering  will be
selected  by the  Majority  Holders of the  Registrable  Notes  included in such
offering,  subject  to  approval  by the  Company,  which  approval  will not be
unreasonably withheld.

          4. PARTICIPATION OF BROKER-DEALERS IN EXCHANGE OFFER.

          (a) The staff of the SEC has taken the position that any broker-dealer
that  receives  Exchange  Notes for its own  account  in the  Exchange  Offer in
exchange  for Notes  that were  acquired  by such  broker-dealer  as a result of
market-making or other trading activities (a "Participating  Broker-Dealer") may
be deemed to be an  "underwriter"  within  the  meaning of the 1933 Act and must
deliver a prospectus meeting the requirements of the 1933 Act in connection with
any resale of such Exchange Notes.

     The  Company  understands  that it is the  position of the staff of the SEC
that if the Prospectus  contained in the Exchange Offer  Registration  Statement
includes a plan of  distribution  containing a statement to the above effect and
the means by which  Participating  Broker-Dealers may resell the Exchange Notes,
without  naming the  Participating  Broker-Dealers  or specifying  the amount of
Exchange Notes owned by them, such Prospectus may be delivered by  Participating
Broker-Dealers  to satisfy their prospectus  delivery  obligation under the 1933
Act in connection with resales of Exchange Notes for their own accounts, so long
as the Prospectus otherwise meets the requirements of the 1933 Act.

          (b) In light of the above,  notwithstanding  the other  provisions  of
this Agreement, the Company agrees that the provisions of this Agreement as they
relate  to  a  Shelf   Registration  shall  also  apply  to  an  Exchange  Offer
Registration to the extent,  and with such reasonable  modifications  thereto as
may  be,  reasonably  requested  by the  Placement  Agents  or by  one  or  more
Participating Broker-Dealers,  in each case as provided in clause (ii) below, in
order to  expedite  or  facilitate  the  disposition  of any  Exchange  Notes by
Participating  Broker-Dealers  consistent with the positions of the staff of the
SEC recited in Section 4(a) above; provided that:

          (i) the  Company  shall not be  required  to amend or  supplement  the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 3(i), for a period  exceeding 180 days
     after the last  Exchange  Date (as such period may be extended  pursuant to
     the penultimate paragraph of Section 3 of this Agreement) and Participating
     Broker-Dealers  shall not be authorized by the Company to deliver and shall
     not  deliver  such  Prospectus  after such  period in  connection  with the
     resales contemplated by this Section 4; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this  Agreement  to an  Exchange  Offer  Registration,  to the
     extent not  required by the  positions  of the staff of the SEC or the 1933
     Act and the rules and  regulations  thereunder,  will be in conformity with
     the reasonable  request to the Company by the Placement  Agents or with the
     reasonable request in writing to the Company by

                                        12

<PAGE>

     one  or  more  broker-dealers  who  certify to the Placement Agents and the
     Company in writing  that they  anticipate  that they will be  Participating
     Broker-Dealers;   and  PROVIDED  FURTHER  that,  in  connection  with  such
     application of the Shelf Registration  procedures set forth in Section 3 to
     an Exchange Offer Registration,  the Company shall be obligated (x) to deal
     only with one entity representing the Participating  Broker-Dealers,  which
     shall be Morgan Stanley & Co.  Incorporated  unless it elects not to act as
     such  representative,  (y) to pay the fees and expenses of only one counsel
     representing the  Participating  Broker-Dealers,  which shall be counsel to
     the Placement  Agents unless such counsel  elects not to so act, and (z) to
     cause to be delivered only one, if any, "cold comfort"  letter with respect
     to the  Prospectus  in the form existing on the last Exchange Date and with
     respect to each subsequent amendment or supplement, if any, effected during
     the period specified in clause (i) above.

          (c) the Placement Agents shall have no liability to the Company or any
Holder with  respect to any request  that it may make  pursuant to Section  4(b)
above.

          5. INDEMNIFICATION AND CONTRIBUTION.

          (a) The Company  agrees to indemnify  and hold  harmless the Placement
Agents, each Holder and each person, if any, who controls any Placement Agent or
any Holder within the meaning of either Section 15 of the 1933 Act or Section 20
of the 1934 Act, or is under  common  control  with,  or is  controlled  by, any
Placement Agent or any Holder, from and against all losses,  claims, damages and
liabilities  (including,   without  limitation,  any  legal  or  other  expenses
reasonably  incurred by any Placement  Agent, any Holder or any such controlling
or affiliated  person in connection  with  defending or  investigating  any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
pursuant to which Exchange Notes or Registrable  Notes were registered under the
1933 Act, including all documents  incorporated therein by reference,  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 not misleading, or
caused by any untrue  statement or alleged  untrue  statement of a material fact
contained in any  Prospectus  (as amended or  supplemented  if the Company shall
have furnished any amendments or supplements thereto), or caused by any omission
or alleged  omission  to state  therein a material  fact  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 such  untrue  statement  or  omission  or alleged
untrue  statement or omission based upon  information  relating to any Placement
Agent or any Holder  furnished to the Company in writing by any Placement  Agent
or any selling  Holder  expressly  for use therein;  PROVIDED THAT the foregoing
indemnity  agreement  shall not inure to the benefit of any Holder or any Person
controlling such Holder,  with respect to any sale or disposition of Registrable
Notes by such Holder in violation of the  penultimate  paragraph of Section 3 of
this  Agreement.  In  connection  with any  Underwritten  Offering  permitted by
Section 3, the Company will also  indemnify the  Underwriters,  if any,  selling
brokers, dealers and similar securities industry professionals  participating in
the distribution, their officers

                                        13

<PAGE>

and directors  and each Person who controls such Persons  (within the meaning of
either  Section  15 of the 1933 Act or  Section  20 of the 1934 Act) to the same
extent as provided above with respect to the  indemnification of the Holders, if
requested in connection with any Registration Statement.

          (b) Each Holder  agrees,  severally and not jointly,  to indemnify and
hold harmless the Company,  each Placement Agent and the other selling  Holders,
and each of  their  respective  directors,  officers  who sign the  Registration
Statement and each Person, if any, who controls the Company, any Placement Agent
and any other selling Holder within the meaning of either Section 15 of the 1933
Act or Section 20 of the 1934 Act to the same extent as the foregoing  indemnity
from the  Company  to the  Placement  Agents  and the  Holders,  but  only  with
reference  to  information  relating to such Holder  furnished to the Company in
writing by such Holder expressly for use in any  Registration  Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).

          (c) In case any proceeding (including any governmental  investigation)
shall be instituted  involving  any Person in respect of which  indemnity may be
sought pursuant to either paragraph (a) or paragraph (b) above, such person (the
"indemnified  party")  shall  promptly  notify  the  Person  against  whom  such
indemnity may be sought (the  "indemnifying  party") in writing (but the failure
to so notify an indemnifying party shall not relieve it from any liability which
it may have under this Section, except to the extent that it has been prejudiced
in any material respect by such failure,  or from any liability it may otherwise
have) and the indemnifying  party, upon request of the indemnified  party, shall
retain counsel reasonably satisfactory to the indemnified party to represent the
indemnified  party and any others the  indemnifying  party may designate in such
proceeding and shall pay the fees and  disbursements  of such counsel related to
such proceeding.  In any such proceeding,  any indemnified  party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified  party unless (i) the  indemnifying  party
and the  indemnified  party shall have mutually  agreed to the retention of such
counsel  or (ii)  the  named  parties  to any  such  proceeding  (including  any
impleaded parties) include both the indemnifying party and the indemnified party
and  representation  of both parties by the same counsel would be  inappropriate
due to actual or potential  differing  interests  between them. It is understood
that the  indemnifying  party shall not, in respect of the legal expenses of any
indemnified  party in connection  with any proceeding or related  proceedings in
the same  jurisdiction,  be liable for (A) the  reasonable  fees and expenses of
more than one separate firm (in addition to any local counsel) for the Placement
Agents and all Persons,  if any,  who control the  Placement  Agents  within the
meaning of either  Section 15 of the 1933 Act or Section 20 of the 1934 Act, (B)
the reasonable  fees and expenses of more than one separate firm (in addition to
any local  counsel) for the Company,  its  directors,  its officers who sign the
Registration  Statement and each Person, if any, who controls the Company within
the meaning of either such Section and (C) the  reasonable  fees and expenses of
more than one separate  firm (in addition to any local  counsel) for all Holders
and all Persons,  if any,  who control any Holders  within the meaning of either
such  Section,  and that all such fees and expenses  shall be reimbursed as they
are  incurred.  In such case  involving  any  Placement  Agents and  Persons who
control such Placement Agent, such firm shall be designated in writing by Morgan
Stanley & Co. Incorporated. In such case involving the

                                           14

<PAGE>


Holders and such Persons who control  Holders,  such firm shall be designated in
writing  by the  Majority  Holders.  In all  other  cases,  such  firm  shall be
designated by the Company.  The  indemnifying  party 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  party agrees to indemnify the  indemnified  party from and against
any loss or liability by reason of such settlement or judgment.  Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying  party to reimburse the indemnified  party for fees and expenses
of counsel as  contemplated by the second and third sentences of this paragraph,
the indemnifying  party agrees that it shall be liable for any settlement of any
proceeding  effected  without  its  written  consent if (x) such  settlement  is
entered into more than 60 days after receipt by such  indemnifying  party of the
aforesaid request and (y) such indemnifying  party shall not have reimbursed the
indemnified  party for such fees and expenses of counsel in accordance with such
request  prior to the date of such  settlement.  No  indemnifying  party  shall,
without the prior written  consent of the  indemnified  party (which consent may
not  be  unreasonably  withheld),  effect  any  settlement  of  any  pending  or
threatened  proceeding  in respect of which such  indemnified  party is or could
have been a party and indemnity could have been sought hereunder (whether or not
any  indemnified  party is an actual or potential  party to such  proceeding) by
such indemnified party, unless such settlement includes an unconditional release
of such  indemnified  party from all  liability  on claims  that are the subject
matter of such proceeding.

          (d) To the extent the indemnification provided for in paragraph (a) or
paragraph  (b) of this  Section  5 is  unavailable  to an  indemnified  party or
insufficient in respect of any losses,  claims,  damages or liabilities referred
to  therein,  then each  indemnifying  party  under such  paragraph,  in lieu of
indemnifying such indemnified  party thereunder,  shall contribute to the amount
paid or payable by such  indemnified  party as a result of such losses,  claims,
damages or  liabilities  in such  proportion  as is  appropriate  to reflect the
relative fault of the indemnifying party or parties, on the one hand, and of the
indemnified  party  or  parties,  on the  other  hand,  in  connection  with the
statements  or  omissions  that  resulted  in such  losses,  claims,  damages or
liabilities,  as  well  as any  other  relevant  equitable  considerations.  The
relative  fault of the Company and the Holders  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  or by the  Holders  and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct  or  prevent  such  statement  or  omission.   The  Holders'  respective
obligations  to  contribute  pursuant  to  this  Section  5(d)  are  several  in
proportion  to the  respective  principal  amount of  Registrable  Notes of such
Holder that were registered pursuant to a Registration Statement.

          (e) The  Company  and each  Holder  agree that it would not be just or
equitable if contribution pursuant to this Section 5 were determined by PRO RATA
allocation  or by any other method of  allocation  that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified  party as a result of the losses,  claims,  damages
and  liabilities  referred to in paragraph (d) above shall be deemed to include,
subject  to the  limitations  set  forth  above,  any  legal or  other  expenses
reasonably incurred by such indemnified party in connection with investigating

                                        15

<PAGE>

or defending any such action or claim.  Notwithstanding  the  provisions of this
Section 5, no Holder shall be required to indemnify or contribute  any amount in
excess of the amount by which the total  price at which  Registrable  Notes were
sold by such  Holder  exceeds  the amount of any  damages  that such  Holder 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 1933 Act) shall be
entitled to  contribution  from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive
and shall not limit any rights or remedies  which may  otherwise be available to
any indemnified party at law or in equity.

          The indemnity and contribution  provisions contained in this Section 5
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
termination of this Agreement,  (ii) any  investigation  made by or on behalf of
any Placement Agent, any Holder or any Person controlling any Placement Agent or
any Holder, or by or on behalf of the Company,  its officers or directors or any
Person  controlling the Company,  (iii)  acceptance of any of the Exchange Notes
and  (iv)  any  sale of  Registrable  Notes  pursuant  to a  Shelf  Registration
Statement.

          6. MISCELLANEOUS.

          (a) NO INCONSISTENT AGREEMENTS.  The Company has not entered into, and
on or after the date of this Agreement will not enter into, any agreement  which
is inconsistent  with the rights granted to the Holders of Registrable  Notes in
this Agreement or otherwise  conflicts with the  provisions  hereof.  The rights
granted to the Holders  hereunder  do not in any way  conflict  with and are not
inconsistent  with the rights  granted to the  holders  of the  Company's  other
issued and outstanding securities under any such agreements.

          (b)  AMENDMENTS  AND  WAIVERS.   The  provisions  of  this  Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given unless the Company has obtained the written  consent of Holders
of at  least  a  majority  in  aggregate  principal  amount  of the  outstanding
Registrable   Notes  which  are  affected  by  such   amendment,   modification,
supplement,   waiver  or  consent;   PROVIDED,   HOWEVER,   that  no  amendment,
modification, supplement, waiver or consent to any departure from the provisions
of Section 5 hereof  shall be  effective  as against  any Holder of  Registrable
Notes unless consented to in writing by such Holder.

          (c)  NOTICES.  All notices and other  communications  provided  for or
permitted  hereunder  shall  be made in  writing  by hand  delivery,  registered
first-class  mail,  telex,  telecopier  or any  courier  guaranteeing  overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address  initially is, with respect to the Placement Agents,
the address set forth in the  Placement  Agreement;  and (ii) if to the Company,
initially at the Company's address set

                                        16

<PAGE>

forth in the Placement Agreement and thereafter at such other address, notice of
which is given in accordance with the provisions of this Section 6(c).

          All such notices and communications  shall be deemed to have been duly
given:  at the time  delivered by hand, if personally  delivered;  five business
days after  being  deposited  in the mail,  postage  prepaid,  if  mailed;  when
answered back, if telexed; when receipt is acknowledged,  if telecopied;  and on
the next  business  day,  if timely  delivered  to an air  courier  guaranteeing
overnight delivery.

          Copies of all such notices,  demands or other  communications shall be
concurrently  delivered  by the person  giving the same to the  Trustee,  at the
address specified in the Indenture.

          (d) SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the benefit
of and be binding upon the  successors,  assigns and  transferees of each of the
parties,  including,  without  limitation  and  without  the need for an express
assignment,  subsequent Holders; PROVIDED THAT nothing herein shall be deemed to
permit any  assignment,  transfer or other  disposition of Registrable  Notes in
violation of the terms of the  Placement  Agreement.  If any  transferee  of any
Holder shall acquire  Registrable Notes, in any manner,  whether by operation of
law or  otherwise,  such  Registrable  Notes shall be held subject to all of the
terms of this Agreement,  and by taking and holding such Registrable  Notes such
person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and  provisions  of this  Agreement  and such  person  shall be
entitled to receive the benefits hereof. The Placement Agents (in their capacity
as the  Placement  Agents)  shall have no liability or obligation to the Company
with  respect to any  failure by a Holder to comply  with,  or any breach by any
Holder of, any of the obligations of such Holder under this Agreement.

          (e) PURCHASES AND SALES OF NOTES. The Company shall not, and shall use
its best efforts to cause its  affiliates (as defined in Rule 405 under the 1933
Act) not to, purchase and then resell or otherwise transfer any Notes.

          (f)  THIRD  PARTY  BENEFICIARY.  The  Holders  shall  be  third  party
beneficiaries to the agreements made hereunder  between the Company,  on the one
hand, and the Placement  Agents,  on the other hand, and shall have the right to
enforce  such  agreements  directly  to the  extent  it deems  such  enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

          (g)  COUNTERPARTS.  This  Agreement  may be  executed in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

          (h) HEADINGS.  The headings in this  Agreement are for  convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (i) GOVERNING LAW. This  Agreement  shall be governed by and construed
in accordance with the internal laws of the State of New York.

          (j) SEVERABILITY.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held
invalid, illegal or unenforceable,  the validity, legality and enforceability of

                          REGISTRATION RIGHTS AGREEMENT


               THIS REGISTRATION  RIGHTS AGREEMENT (the "AGREEMENT") is made and
entered  into on April 6,  2000  between  VIATEL  FINANCING  TRUST I, a  special
statutory  trust formed under the laws of the State of Delaware  (the  "TRUST"),
VIATEL,  INC., a Delaware  corporation  ("VIATEL" or the "COMPANY"),  and MORGAN
STANLEY & CO.  INCORPORATED,  SALOMON  SMITH  BARNEY  INC.  and BANC OF  AMERICA
SECURITIES LLC (the "PLACEMENT AGENTS").

               This Agreement is made pursuant to the Placement Agreement, dated
the date hereof,  between the Trust,  the Company and the Placement  Agents (the
"PLACEMENT  AGREEMENT").  In order to induce the Placement  Agents to enter into
the  Placement  Agreement,  the Trust and the Company have agreed to provide the
registration rights set forth in this Agreement. The execution of this Agreement
is a condition to the closing under the Purchase Agreement.

               The Trust and the Company  agree with the Placement  Agents,  (i)
for their  benefit as  Placement  Agents and (ii) for the benefit of the holders

<PAGE>

               (a) SHELF  REGISTRATION.  The Company and the Trust shall prepare
and file with the SEC,  as soon as  practicable  but in any event on or prior to
the date ninety (90) days following the latest date of original  issuance of the
Convertible  Preferred Securities (the "FILING DATE"), a registration  statement
for an offering to be made on a delayed or continuous basis pursuant to Rule 415
of the 1933 Act (the "SHELF  REGISTRATION")  registering the resale from time to
time by Holders thereof of all of the Registrable Securities (the "INITIAL SHELF
REGISTRATION").  The Initial Shelf  Registration shall be on Form S-3 or another
appropriate  form  permitting  registration  of the  Registrable  Securities for
resale  by  the  Holders  in  one  or  more  Underwritten  Offerings,  privately
negotiated  transactions,  sales on the Nasdaq National Market, sales to brokers
or dealers or  otherwise.  The Company and the Trust shall use their  reasonable
best efforts to cause the Initial Shelf  Registration  to be declared  effective

after the date hereof, and to keep the Initial Shelf  Registration  continuously
effective  under the 1933 Act until the earlier of the end of the  Effectiveness
Period.

               (b) If the Initial Shelf  Registration  or any  Subsequent  Shelf
Registration  (as defined  below)  ceases to be effective  for any reason at any
time  during the  Effectiveness  Period  (other  than  because  all  Registrable
Securities registered thereunder shall have been sold or shall have ceased to be
Registrable  Securities),  the Company and the Trust shall use their  reasonable
best  efforts  to obtain  the  prompt  withdrawal  of any order  suspending  the
effectiveness  thereof,  and in any event shall, subject to Section 2(d), within
thirty  (30)  days  of  such  cessation  of   effectiveness   amend  such  Shelf
Registration  in a manner  reasonably  expected to obtain the  withdrawal of the
order  suspending  the  effectiveness  thereof,  or  file  an  additional  Shelf
Registration  covering all of the  Registrable  Securities (a "SUBSEQUENT  SHELF
REGISTRATION"). If a Subsequent Shelf Registration is filed, the Company and the
Trust shall use their  reasonable  best efforts to cause such  Subsequent  Shelf
Registration to be declared  effective as soon as practicable  after such filing
and to keep such Registration  Statement continuously effective until the end of
the Effectiveness Period.

               (c) The  Company  and the Trust  shall  supplement  and amend the
Shelf  Registration  if  required  by the  rules,  regulations  or  instructions
applicable to the  registration  form under the 1933 Act used by the Company and
the  Trust  for  such  Shelf  Registration,  if  required  by the 1933 Act or if
reasonably  requested  by the  Placement  Agents on behalf of the Holders of the
Registrable Securities covered by such Registration Statement or by the Managing
Underwriters of such Registrable Securities;  provided that the party or parties

                                       6
<PAGE>

making such request shall have  furnished to the Company and the Trust with such
request a written  description  of such  request and  reasonable  legal  grounds
therefor.

               (d) Each  Holder of  Registrable  Securities  agrees that if such
Holder  wishes to  distribute  its  Registrable  Securities  pursuant to a Shelf
Registration and related Prospectus,  it will do so only in accordance with this
Section  2(d).  Each Holder of  Registrable  Securities  agrees to give  written
notice  to the  Company  and the Trust  prior to any  intended  distribution  of
Registrable Securities under the Shelf Registration,  which notice shall specify
the  date on which  such  Holder  intends  to begin  such  distribution  and any
information  with  respect  to such  Holder  and the  intended  distribution  of
Registrable  Securities  by such  Holder  required  to  amend  the  Registration
Statement with respect to such intended  distribution of Registrable  Securities
by such Holder.  Within five business days after such date,  the Company and the
Trust shall either:

               (i)  (A)  If   necessary,   prepare  and  file  with  the  SEC  a
          post-effective  amendment to the Shelf Registration or a supplement to
          the related  Prospectus  or a supplement  or amendment to any document
          incorporated  therein by reference or file any other required document
          so that  such  Registration  Statement  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 not
          misleading,  and so that, as thereafter delivered to purchasers of the
          Registrable Securities being sold thereunder, 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 light of the  circumstances  under which they
          were made, not misleading;  (B) provide the Holders of the Registrable
          Securities who gave such notice copies of any documents filed pursuant
          to  Section  2(d)(i)(A);  and (C)  inform  each such  Holder  that the
          Company and the Trust have complied with their  obligations in Section
          2(d)(i)(A) and that the Registration  Statement and the Prospectus may
          be used for sales of  Registrable  Securities (or that, if the Company
          or the  Trust  has  filed  a  post-effective  amendment  to the  Shelf
          Registration  which has not yet been declared  effective,  the Company
          and the Trust will notify each such  Holder to that  effect,  will use
          reasonable efforts to secure the effectiveness of such  post-effective
          amendment  and will  immediately  notify each such Holder  pursuant to
          Section  2(d)(i)(A) hereof when the amendment has become effective and
          that the  Registration  Statement and the  Prospectus  may be used for
          sales of Registrable Securities).

               Each Holder who has given notice of intention to distribute  such
          Holder's  Registrable  Securities in accordance with this Section 2(d)
          (a  "NOTICE  HOLDER")  shall  distribute  all or any such  Registrable
          Securities  pursuant to the Shelf  Registration and related Prospectus
          only during the 45-day  period  commencing  with the date on which the
          Company and the Trust give such notice (such 45-day period is referred
          to as a "SELLING PERIOD").  The Notice Holders will not distribute any

                                       7
<PAGE>

          Registrable  Securities  pursuant to such  Registration  Statement  or
          Prospectus  after such Selling  Period  without giving a new notice of
          intention to distribute  pursuant to Section 2(d) hereof and receiving
          a further  notice from the  Company and the Trust  pursuant to Section
          2(d)(i)(C) hereof.

               (ii) In the event of the  happening  of any event (A) of the kind
          described in Section  2(e) hereof or (B) that the Company  believes in
          good faith makes it advisable to suspend use of the  Prospectus  for a
          discrete period of time due to pending material corporate developments
          or similar  material events that have not yet been publicly  disclosed
          and as to  which  the  Company  believes  in good  faith  that  public
          disclosure will be  disadvantageous  to the Company or the Trust,  the
          Company shall deliver a  certificate  in writing,  signed by its Chief
          Executive Officer or Chief Financial  Officer,  to the Notice Holders,
          and the Managing Underwriters,  if any, to the effect of the foregoing
          and,  upon  receipt of such  certificate,  each such  Notice  Holder's
          Selling  Period will not  recommence or shall be suspended  until such
          Notice  Holder's  receipt  of copies of the  supplemented  or  amended
          Prospectus  provided for in Section  2(d)(i)(A) hereof, or until it is
          advised in writing by the Company that the Prospectus may be used, and
          it has received copies of any additional or supplemental  filings that
          are   incorporated  or  deemed   incorporated  by  reference  in  such
          Prospectus.  The Company and the Trust will use their  reasonable best
          efforts to ensure that the use of the Prospectus  may be resumed,  and
          the Selling Period will commence or recommence, as soon as practicable
          and,  in the case of a pending  development  or event  referred  to in
          Section  2(d)(ii)(B)  hereof,  as soon as the  earlier  of (x)  public
          disclosure of such pending material  corporate  development or similar
          material  event or (y) the date  upon  which  in the  judgment  of the
          Company,  public disclosure of such material corporate  development or
          similar material event would not be  disadvantageous to the Company or
          the Trust.  Notwithstanding  the foregoing,  the period during which a
          Selling  Period  is  suspended,  whether  or not  consecutive,  in any
          12-month period, shall not exceed 60 days (a "DEFERRAL PERIOD").

               (e) The  parties  hereto  agree that the  Holders of  Registrable
Securities will suffer  damages,  and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) the Initial Shelf Registration
has not been filed on or prior to the Filing Date,  (ii) prior to the end of the
Effectiveness  Period,  the SEC shall have  issued a stop order  suspending  the
effectiveness of the Shelf  Registration,  (iii) the aggregate number of days in
any one  Deferral  Period  exceeds  the  periods  permitted  pursuant to Section
2(d)(ii)  hereof  or  (each  of the  events  of a type  described  in any of the
foregoing  clauses (i) through (iii) are  individually  referred to herein as an
"Event,"  and the Filing Date in the case of clause  (i),  the date on which the
effectiveness  of the Shelf  Registration has been suspended or proceedings with
respect to the Shelf  Registration  under  Section  8(d) or 8(e) of the 1933 Act
have been  commenced in the case of clause (ii),  the date on which the duration
of a Deferral  Period exceeds the aggregate  number of days permitted by Section
2(d)(ii)  hereof being referred to herein as an "EVENT  DATE").  Events shall be
deemed to  continue  until the  "EVENT  TERMINATION  DATE,"  which  shall be the

                                       8
<PAGE>

following  dates with respect to the  respective  types of Events:  the date the
Initial  Registration  Statement  is  filed  in the case of an Event of the type
described in clause (i), the date that all stop orders suspending  effectiveness
of the Shelf  Registration have been removed and the proceedings  initiated with
respect to the Shelf Registration under Section 8(d) or (e) of the 1933 Act have
terminated,  as the case may be, in the case of Events of the types described in
clause (ii), and  termination  of the Deferral  Period which caused the limit on
the duration of a Deferral  Period set forth in Section  2(d)(ii) to be exceeded
in the case of the  commencement  of an Event of the type  described  in  clause
(iii).

               Accordingly, upon the occurrence of any Event Date and until such
time as there are no Events which have  occurred and are  continuing (a "DAMAGES
ACCRUAL  PERIOD"),  commencing  on and  including  the Event  Date on which such
Damages Accrual Period began, the Company agrees to pay, as liquidated  damages,
and not as a penalty,  an additional  amount (the "LIQUIDATED  DAMAGES AMOUNT"):
(i) to each Holder of (x) a Convertible  Preferred  Security or (y) in the event
that the  Convertible  Debentures  are  distributed  to holders  of  Convertible
Preferred  Securities  upon  dissolution  of the  Trust in  accordance  with the
Declaration,  a Convertible  Debenture,  accruing at a rate equal to one-half of
one percent per annum (50 basis  points) on an amount  equal to the  liquidation
amount  of such  Convertible  Preferred  Security  or  principal  amount of such
Convertible Debenture,  as the case may be, held by such Holder and (ii) to each
Holder of Underlying  Common Stock,  accruing at a rate equal to one-half of one
percent per annum (50 basis points) calculated on an amount equal to the product
of (x) the Applicable  Conversion Price as of the business day immediately prior
to the applicable  Damages Payment Date times (y) the number of shares of Common
Stock   that  are   Registrable   Securities   held  by  such   Notice   Holder.
Notwithstanding  the foregoing,  no Liquidated Damages Amounts shall accrue with
respect to any  Registrable  Security from and after the earlier of (x) the date
such security is no longer a  Registrable  Security,  and (y)  expiration of the
Effectiveness  Period. The rate of accrual of the Liquidated Damages Amount with
respect to any period shall not exceed the rate  provided for in this  paragraph
notwithstanding the occurrence of multiple concurrent Events. Liquidated Damages
Amounts  shall be  computed  on the  basis of a 360-day  year of  twelve  30-day
months,  PROVIDED that Liquidated Damages Amounts payable for any period shorter
than a month will be computed on the basis of the actual  number of days elapsed
per 30- day month.

               The  Company  shall  pay  the  liquidated   damages  due  on  any
Convertible Preferred Security, Convertible Debenture or Underlying Common Stock
by  depositing  with the  Trustee,  in trust for the  benefit of the  Holders of
Convertible Preferred Securities or Convertible Debentures entitled thereto (or,
in the case of Underlying  Common Stock,  by depositing  with the transfer agent
for the benefit of the Holders of Underlying Common Stock entitled thereto),  as
the case may be,  at least one  business  day  prior to the  applicable  Damages
Payment Date, sums sufficient to pay all accrued and unpaid  liquidated  damages
from and including  the last Damages  Payment Date to which  liquidated  damages
have been paid in full (or, if no  liquidated  damages have been paid in respect
of the relevant Damages Accrual Period, from and including the first day of such

                                       9
<PAGE>

Damages  Accrual  Period) to, but  excluding,  such Damages  Payment  Date.  The
Liquidated  Damages Amount due shall be payable on each Damages  Payment Date to
the Holders of Registrable  Securities entitled thereto holding such Registrable
Securities on the record date for such Damages  Payment Date (which record date,
in the case of Underlying Common Stock,  shall be established by the Company but
shall in any  event be  between  10 and 60 days  prior to the  relevant  Damages
Payment  Date);  PROVIDED  that,  if any  Convertible  Preferred  Securities  or
Convertible Debentures (or portions thereof) are called for redemption,  accrued
and unpaid  liquidated  damages  thereon shall be paid to the person entitled to
receive accrued and unpaid interest  thereon;  and PROVIDED  FURTHER that if any
Convertible  Preferred Security or Convertible Debenture (or portion thereof) is
surrendered  for  conversion  from and after the close of  business on a regular
record  date and prior to the  corresponding  distribution  payment or  interest
payment  date,  as the case may be, then accrued and unpaid  liquidated  damages
thereon  shall be paid to the  person  entitled  to receive  accrued  and unpaid
distributions  or interest,  as the case may be, in respect of such  Convertible
Preferred Security or Convertible Debenture (or portion thereof) as the case may
be;  and  PROVIDED  FURTHER  that  if  any  Convertible  Preferred  Security  or
Convertible  Debenture (or portion thereof) is surrendered for conversion at any
other time, then the converting  Holder thereof shall be entitled to receive all
accrued  and unpaid  Liquidated  Damages  thereon to but  excluding  the date of
conversion.  The Trustee shall be entitled,  on behalf of the Notice Holders and
the Holders of  Convertible  Preferred  Securities,  Convertible  Debentures  or
Underlying  Common Stock,  to seek any available  remedy for the  enforcement of
this  Agreement,   including  for  the  payment  of  such  liquidated   damages.
Notwithstanding  the foregoing,  the parties agree that the sole damages payable
for a violation of the terms of this Agreement with respect to which  liquidated
damages are expressly provided shall be such liquidated damages.

               All of the Company's  obligations  set forth in this Section 2(e)
which are  outstanding  with respect to any  Registrable  Securities at the time
such security ceases to be a Registrable  Security shall survive until such time
as all such  obligations  with respect to such security  have been  satisfied in
full.

               The parties hereto agree that the liquidated damages provided for
in this Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by holders of Registrable Securities,  other than the Placement Agents,
by  reason of the  failure  of the Shelf  Registration  to be filed or  declared
effective or  unavailable  (absolutely  or as a practical  matter) for effecting
resales of Registrable  Securities,  as the case may be, in accordance  with the
provisions hereof.

               (f) The Company shall pay all Registration Expenses in connection
with  the  registration  pursuant  to  Section  2.  Each  Holder  shall  pay all
underwriting  discounts and commissions and transfer taxes, if any,  relating to
the sale or disposition of such Holder's Registrable  Securities pursuant to the
Shelf Registration.

          proceeding for such purpose,  (v) of the happening of any event during

          representing  Registrable  Securities  to be sold and not  bearing any
          restrictive  legends and enable such  Registrable  Securities to be in
          such denominations and registered in such names as the selling Holders
          may reasonably request at least two business days prior to the closing
          of any sale of Registrable Securities;

               (i) upon the  occurrence  of any event  contemplated  by  Section
          3(e)(v)  hereof,  use their best  efforts to prepare and file with the
          SEC  a  supplement  or  post-effective  amendment  to  a  Registration
          Statement  or the  related  Prospectus  or any  document  incorporated
          therein by reference or file any other  required  document so that, as
          thereafter delivered to the purchasers of the Registrable  Securities,
          such  Prospectus  will not contain any untrue  statement of a material
          fact or omit to state a material fact necessary to make the statements
          therein, in the light of the circumstances under which they were made,

          Prospectus after initial filing of a Registration  Statement,  provide
          copies of such document to the Holders and their counsel and make such
          of the representatives of the Company as shall be reasonably requested
          by the  Holders or their  counsel  available  for  discussion  of such
          document,  and shall not at any time file or make any amendment to the
          Registration  Statement,   any  Prospectus  or  any  amendment  of  or
          supplement to a Registration Statement or a Prospectus or any document
          (other than a document  which the Company is legally  required to file
          under the 1934 Act) which is to be  incorporated  by reference  into a
          Registration Statement or a Prospectus, of which the Holders and their
          counsel shall not have previously been advised and furnished a copy or

          Registration Statement to be registered with or approved by such other
          governmental  agencies or authorities within the United States (except
          as may be  required  solely  as a  consequence  of the  nature of such
          selling  Holder,  in which case Viatel and the Trust will cooperate in
          all reasonable respects with the filing of such Registration Statement
          and the granting of such  approvals) as may be necessary to enable the
          selling  Holder or Holders  thereof to consummate  the  disposition of

          of Registrable Securities covered by such Registration Statement,  (i)
          promptly  incorporate  in a Prospectus  supplement  or  post-effective
          amendment such  information  with respect to such Holder as is legally
          required to be included  therein and (ii) make all required filings of
          such Prospectus supplement or such post-effective amendment as soon as
          the Company and the Trust have received notification of the matters to
          be incorporated in such filing;

               (o)  use  their  reasonable  best  efforts  to  enter  into  such
          customary  agreements  and take all such other  actions in  connection
          therewith  (including  those requested by the Holders of a majority of
          the  Registrable  Securities  being  sold)  in order  to  expedite  or
          facilitate the disposition of such Registrable  Securities  including,
          but not limited to, an Underwritten  Offering and in such  connection,
          (i) to the extent possible,  make such  representations and warranties
          to the Holders and any  Underwriters  of such  Registrable  Securities
          with respect to the business of the Company and its subsidiaries,  the
          Shelf Registration, Prospectus and documents incorporated by reference
          therein or deemed  incorporated by reference therein,  if any, in each
          case, in form,  substance and scope as are customarily made by issuers
          to underwriters in Underwritten  Offerings and confirm the same if and
          when  requested,  (ii) use their  reasonable  best  efforts  to obtain
          opinions of counsel to the Company  (which  counsel and  opinions,  in
          form,  scope and substance,  shall be reasonably  satisfactory  to the
          Holders and such Underwriters and their respective  counsel) addressed

                                       14

          to each selling  Holder and  Underwriter  of  Registrable  Securities,
          covering  the matters  customarily  covered in opinions  requested  in
          underwritten  offerings,  (iii) use their  reasonable  best efforts to
          obtain "cold comfort"  letters from the independent  certified  public
          accountants  of the Company (and, if  necessary,  any other  certified
          public accountant of any subsidiary of the Company, or of any business
          acquired by the Company for which  financial  statements and financial
          data are or are required to be included in the Registration Statement)
          addressed  to each  selling  Holder  and  Underwriter  of  Registrable
          Securities,  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  (iv)  deliver  such
          documents  and  certificates  as may be  reasonably  requested  by the
          Holders of a majority of the Registrable  Securities being sold or the
          Underwriters,  and which are  customarily  delivered  in  underwritten
          offerings,  to evidence the continued validity of the  representations
          and warranties of the Company made pursuant to clause (i) above and to
          evidence  compliance  with any  customary  conditions  contained in an
          underwriting agreement;

               (q) cooperate with the selling Holders of Registrable  Securities
          to  facilitate  the timely  preparation  and delivery of  certificates
          representing  Registrable  Securities  to be sold and not  bearing any
          restrictive legends;  and enable such Registrable  Securities to be in
          such  denominations  and  registered  in such names as the Holders may
          request;

               (r) cause all Underlying Common Stock covered by the Registration
Statement to be listed on each securities  exchange or quotation system on which
the  Common  Stock  is then  listed  no later  than  the  date the  Registration
Statement is declared  effective  and, in  connection  therewith,  to the extent
applicable,  to make such  filings  under the 1934 Act  (E.G.,  the  filing of a
Registration  Statement on Form 8-A) and to have such filings declared effective
thereunder.

               The Company and the Trust may require each Holder of  Registrable
Securities to furnish to the Company such  information  regarding the Holder and
the proposed  distribution by such Holder of such Registrable  Securities as the
Company  may from  time to time  reasonably  request  in  writing.  No Holder of
Registrable   Securities  may  include  its   Registrable   Securities  in  such
Registration  Statement  unless and until such Holder furnishes such information
to  the  Company.  Each  Holder  including  Registrable  Securities  in a  Shelf
Registration  shall agree to furnish  promptly  to the  Company any  information
regarding  such  Holder and the  proposed  distribution  by such  Holder of such
Registrable  Securities required to make any information previously furnished to
the Company by such Holder not materially misleading.

               Each  Holder  agrees  that,  upon  receipt of any notice from the
Company  or the Trust of the  happening  of any event of the kind  described  in
Section 3(e)(v) hereof,  such Holder will forthwith  discontinue  disposition of
Registrable  Securities  pursuant to a Shelf  Registration  until such  Holder's
receipt of the copies of the supplemented or amended Prospectus  contemplated by

                                       15
<PAGE>

Section  3(i)  hereof,  and,  if so directed  by the  Company,  such Holder will
deliver to the Company (at its expense) all copies in its possession, other than
permanent  file  copies  then in such  Holder's  possession,  of the  Prospectus
covering  such  Registrable  Securities  current  at the time of receipt of such
notice.  If the Company shall give any such notice to suspend the disposition of
Registrable  Securities  pursuant to a Shelf  Registration,  the Company and the
Trust shall extend the period during which the  Registration  Statement shall be
maintained effective pursuant to this Agreement by the number of days during the
period from and including the date of the giving of such notice to and including
the date when the Holders  shall have  received  copies of the  supplemented  or
amended Prospectus necessary to resume such dispositions.  There may not be more
than two such suspensions during any 365 day period and any such suspensions may
not exceed 30 days for each suspension.

               The  Holders  of  Registrable   Securities  covered  by  a  Shelf
Registration  who  desire to do so may sell such  Registrable  Securities  in an
Underwritten Offering; PROVIDED that the Company and the Trust shall be required
to use their  reasonable  best efforts to effect an  underwritten  offering only
upon the  request  of  Holders  of at least  25% of the  Registrable  Securities
outstanding  at the time such request is  delivered to the Company.  In any such
Underwritten  Offering,  the investment banker or investment bankers and manager
or managers  (the  "UNDERWRITERS")  that will  administer  the offering  will be
selected by the Majority Holders of the Registrable  Securities included in such
offering,  subject  to  approval  by the  Company,  which  approval  will not be
unreasonably withheld.

               4. HOLDER'S OBLIGATIONS.

               Each Holder, severally and not jointly, agrees, by acquisition of
the Registrable Securities, that such Holder of Registrable Securities shall not
be  entitled  to  sell  any  of  such  Registrable   Securities  pursuant  to  a
Registration Statement or to receive a Prospectus relating thereto,  unless such
Holder has furnished  Viatel and the Trust with the notice required  pursuant to
Section  2(d) hereof  (including  the  information  required to  accompany  such
notice)  and,  promptly  after the  request by Viatel and the Trust,  such other
information  regarding  such  Holder and the  distribution  of such  Registrable
Securities  as Viatel  and the Trust may from time to time  reasonably  request.
Viatel  and the  Trust  may  exclude  from  such  registration  the  Registrable
Securities of any Holder who does not furnish such  information  provided  above
for so long as such information is not so furnished.  Each Holder of Registrable
Securities as to which any Registration  Statement is being effected,  severally
and not  jointly,  agrees  promptly  to  furnish  to  Viatel  and the  Trust all
information required to be disclosed in order to make the information previously
furnished to Viatel and the Trust by such Holder not misleading. Any sale of any
Registrable  Securities  by any Holder  shall  constitute a  representation  and
warranty  by such  Holder,  severally  and not  jointly,  that  the  information
relating  to such  Holder  and its plan of  distribution  is as set forth in the
Prospectus  delivered by such Holder in connection with such  disposition,  that

                                       16
<PAGE>

such  Prospectus  does  not as of the  time  of such  sale  contain  any  untrue
statement of a material fact relating to such Holder or its plan of distribution
and that such  Prospectus does not as of the time of such sale omit to state any
material fact relating to such Holder or its plan of  distribution  necessary to
make the statements in such Prospectus,  in the light of the circumstances under
which they were made, not misleading.

               5. INDEMNIFICATION AND CONTRIBUTION.

               (a) The  Company  agrees  to  indemnify  and  hold  harmless  the
Placement  Agents,  each  Holder  and each  person,  if any,  who  controls  the
Placement  Agents or any Holder  within the meaning of either  Section 15 of the
1933 Act or Section 20 of the 1934 Act, or is under common  control  with, or is
controlled by, the Placement Agents or any Holder,  from and against all losses,
claims,  damages and liabilities  (including,  without limitation,  any legal or
other expenses  reasonably  incurred by the Placement Agents,  any Holder or any
such   controlling  or  affiliated   person  in  connection  with  defending  or
investigating  any such  action or  claim)  caused by any  untrue  statement  or
alleged  untrue  statement  of a material  fact  contained  in any  Registration
Statement (or any amendment  thereto) pursuant to which  Registrable  Securities
were registered under the 1933 Act, including all documents incorporated therein
by reference,  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 not  misleading,  or caused by any untrue  statement  or alleged  untrue
statement  of a  material  fact  contained  in any  Prospectus  (as  amended  or
supplemented  if the Company shall have  furnished any amendments or supplements
thereto),  or caused by any  omission  or alleged  omission  to state  therein a
material  fact  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 such untrue statement
or omission or alleged  untrue  statement  or  omission  based upon  information
relating  to the  Placement  Agents or any Holder  furnished  to the  Company in
writing by the Placement Agents or any selling Holder expressly for use therein;
PROVIDED that the foregoing  indemnity  agreement shall not inure to the benefit
of any Holder or any Person controlling such Holder, with respect to any sale or
disposition  of  Registrable  Securities  by such  Holder  in  violation  of the
penultimate  paragraph of Section 3 of this  Agreement.  In connection  with any
Underwritten  Offering  permitted by Section 3, the Company will also  indemnify
the  Underwriters,  if any,  selling  brokers,  dealers and  similar  securities
industry  professionals  participating in the  distribution,  their officers and
directors  and each  Person who  controls  such  Persons  (within the meaning of
either  Section  15 of the 1933 Act or  Section  20 of the 1934 Act) to the same
extent as provided above with respect to the  indemnification of the Holders, if
requested in connection with any Registration Statement.

               The foregoing notwithstanding, the Company shall not be liable to
the extent that such losses,  claims, damages or liabilities arise out of or are
based upon an untrue  statement  or alleged  untrue  statement  or  omission  or
alleged omission made in any Prospectus that is a preliminary  prospectus if (i)
such indemnified  person failed to send or deliver a copy of the Prospectus with
or prior to the  delivery  of written  confirmation  of the dale of  Registrable

                                       17
<PAGE>

Securities giving rise to such losses,  claims,  damages or liabilities and (ii)
the Prospectus would have corrected such untrue statement or omission.

               (b) Each Holder agrees,  severally and not jointly,  to indemnify
and hold  harmless  the  Company,  the  Placement  Agents and the other  selling
Holders,  and  each  of  their  respective  directors,  officers  who  sign  the
Registration  Statement and each Person,  if any, who controls the Company,  the
Placement  Agents and any other  selling  Holder  within  the  meaning of either
Section 15 of the 1933 Act or  Section 20 of the 1934 Act to the same  extent as
the  foregoing  indemnity  from the  Company  to the  Placement  Agents  and the
Holders,  but  only  with  reference  to  information  relating  to such  Holder
furnished  to the  Company in writing by such  Holder  expressly  for use in any
Registration  Statement (or any  amendment  thereto) or any  Prospectus  (or any
amendment or supplement thereto).

                  (c)  In  case  any  proceeding   (including  any  governmental
investigation)  shall be  instituted  involving  any  Person in respect of which
indemnity may be sought pursuant to either paragraph (a) or paragraph (b) above,
such person (the  "INDEMNIFIED  PARTY") shall promptly notify the Person against
whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing (but the
failure  to so notify  an  indemnifying  party  shall  not  relieve  it from any
liability which it may have under this Section, except to the extent that it has
been prejudiced in any material  respect by such failure,  or from any liability
it  may  otherwise  have)  and  the  indemnifying  party,  upon  request  of the
indemnified  party,   shall  retain  counsel  reasonably   satisfactory  to  the
indemnified  party  to  represent  the  indemnified  party  and any  others  the
indemnifying  party may designate in such  proceeding and shall pay the fees and
disbursements  of  such  counsel  related  to  such  proceeding.   In  any  such
proceeding,  any  indemnified  party  shall  have the  right to  retain  its own
counsel,  but the fees and expenses of such  counsel  shall be at the expense of
such  indemnified  party unless (i) the  indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall  not,  in  respect  of the  legal  expenses  of any  indemnified  party in
connection with any proceeding or related  proceedings in the same jurisdiction,
be liable for (A) the  reasonable  fees and  expenses of more than one  separate
firm (in  addition  to any  local  counsel)  for the  Placement  Agents  and all
Persons,  if any, who control the Placement  Agents within the meaning of either
Section  15 of the 1933 Act or Section  20 of the 1934 Act,  (B) the  reasonable
fees and  expenses  of more than one  separate  firm (in  addition  to any local
counsel) for the Trust and the Company, its directors, its officers who sign the
Registration  Statement and each Person, if any, who controls the Company or the
Trust within the meaning of either such Section and (C) the reasonable  fees and
expenses of more than one separate  firm (in addition to any local  counsel) for
all Holders and all Persons,  if any, who control any Holders within the meaning
of either such Section,  and that all such fees and expenses shall be reimbursed
as they are  incurred.  In cases  involving  the  Placement  Agents and  Persons

                                       18
<PAGE>

controlling  the  Placement  Agents,  the firm shall be designated in writing by
Morgan Stanley & Co. Incorporated. In the case of any such separate firm for the
Company and the Trust and any such control  persons of the Company or the Trust,
such firm shall be designated in writing by the Company.  In such case involving
the Holders and such Persons who control Holders,  such firm shall be designated
in writing  by the  Majority  Holders.  In all other  cases,  such firm shall be
designated by the Company.  The  indemnifying  party 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  party agrees to indemnify the  indemnified  party from and against
any loss or liability by reason of such settlement or judgment.  Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying  party to reimburse the indemnified  party for fees and expenses
of counsel as  contemplated by the second and third sentences of this paragraph,
the indemnifying  party agrees that it shall be liable for any settlement of any
proceeding  effected  without  its  written  consent if (x) such  settlement  is
entered into more than 60 days after receipt by such  indemnifying  party of the
aforesaid request and (y) such indemnifying  party shall not have reimbursed the
indemnified  party for such fees and expenses of counsel in accordance with such
request  prior to the date of such  settlement.  No  indemnifying  party  shall,
without the prior written  consent of the  indemnified  party (which consent may
not  be  unreasonably  withheld),  effect  any  settlement  of  any  pending  or
threatened  proceeding  in respect of which such  indemnified  party is or could
have been a party and indemnity could have been sought hereunder (whether or not
any  indemnified  party is an actual or potential  party to such  proceeding) by
such indemnified party, unless such settlement includes an unconditional release
of such  indemnified  party from all  liability  on claims  that are the subject
matter of such proceeding.

               (d) To the extent the  indemnification  provided for in paragraph
(a) or paragraph (b) of this Section 5 is unavailable to an indemnified party or
insufficient in respect of any losses,  claims,  damages or liabilities referred
to  therein,  then each  indemnifying  party  under such  paragraph,  in lieu of
indemnifying such indemnified  party thereunder,  shall contribute to the amount
paid or payable by such  indemnified  party as a result of such losses,  claims,
damages or  liabilities  in such  proportion  as is  appropriate  to reflect the
relative fault of the indemnifying party or parties, on the one hand, and of the
indemnified  party  or  parties,  on the  other  hand,  in  connection  with the
statements  or  omissions  that  resulted  in such  losses,  claims,  damages or
liabilities,  as  well  as any  other  relevant  equitable  considerations.  The
relative fault of the Company,  the Trust and the Holders 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, the Trust or by the Holders and
the parties' relative intent,  knowledge,  access to information and opportunity
to correct or prevent  such  statement  or  omission.  The  Holders'  respective
obligations  to  contribute  pursuant  to  this  Section  5(d)  are  several  in
proportion to the respective principal amount of Registrable  Securities of such
Holder that were registered pursuant to a Registration Statement.

                                       19
<PAGE>

               (e) The  Company,  the Trust and each Holder  agree that it would
not be just or  equitable  if  contribution  pursuant  to  this  Section  5 were
determined by PRO RATA allocation or by any other method of allocation that does
not take account of the  equitable  considerations  referred to in paragraph (d)
above.  The amount  paid or payable by an  indemnified  party as a result of the
losses, claims, damages and liabilities referred to in paragraph (d) above shall
be deemed to include,  subject to the limitations set forth above,  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or  defending  any such  action  or  claim.  Notwithstanding  the
provisions  of this  Section 5, no Holder  shall be  required  to  indemnify  or
contribute  any amount in excess of the amount by which the total price at which
Registrable  Securities  were  sold by such  Holder  exceeds  the  amount of any
damages that such Holder 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 1933 Act)  shall be  entitled  to  contribution  from any person who was not
guilty of such fraudulent  misrepresentation.  The remedies provided for in this
Section 5 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.

               The  indemnity  and  contribution  provisions  contained  in this
Section 5 shall remain operative and in full force and effect  regardless of (i)
any termination of this Agreement,  (ii) any investigation  made by or on behalf
of the  Placement  Agents,  any Holder or any Person  controlling  the Placement
Agents or any  Holder,  or by or on  behalf of the  Trust,  the  Company,  their
officers or  directors  or any Person  controlling  the Trust or the Company and
(iii) any sale of Registrable Securities by any Holder.

               6. MISCELLANEOUS.

               (a) NO INCONSISTENT AGREEMENTS. Neither the Company nor the Trust
has entered into,  and on or after the date of this  Agreement  will enter into,
any agreement  which is  inconsistent  with the rights granted to the Holders of
Registrable  Securities  in this  Agreement  or  otherwise  conflicts  with  the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's or the Trust's other issued and outstanding  securities  under any
such agreements.

               (b)  AMENDMENTS AND WAIVERS.  The  provisions of this  Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given  unless the  Company  and the Trust have  obtained  the written
consent of Holders of at least a  majority  of the then  outstanding  Underlying
Common Stock  constituting  Registrable  Securities (with Holders of Convertible
Preferred  Securities deemed to be the Holders, for purposes of this Section, of
the number of  outstanding  shares of  Underlying  Common  Stock into which such
Convertible  Preferred  Securities are  convertible or  exchangeable  or, in the
event that the  Convertible  Debentures  have been  distributed  to Holders upon
liquidation of the Trust,  with the Holders of Convertible  Debentures deemed to

                                       20
<PAGE>

be the Holders,  for purposes of this Section,  the number of outstanding shares
of  Underlying   Common  Stock  into  which  such  Convertible   Debentures  are
convertible);  PROVIDED, HOWEVER, that no amendment,  modification,  supplement,
waiver or consent to any departure from the provisions of Section 5 hereof shall
be effective as against any Holder of Registrable Securities unless consented to
in writing by such Holder.

               (c) NOTICES. All notices and other communications provided for or
permitted  hereunder  shall  be made in  writing  by hand  delivery,  registered
first-class  mail,  telex,  telecopier  or any  courier  guaranteeing  overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address  initially is, with respect to the Placement Agents,
the address set forth in the Purchase  Agreement;  and (ii) if to the Company or
the Trust,  initially at the Company's or the Trust's address,  respectively set
forth in the Placement Agreement and thereafter at such other address, notice of
which is given in accordance with the provisions of this Section 6(c).

               All such notices and communications  shall be deemed to have been
duly  given:  at the time  delivered  by hand,  if  personally  delivered;  five
business days after being  deposited in the mail,  postage  prepaid,  if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next  business  day, if timely  delivered to an air courier  guaranteeing
overnight delivery.

               Copies of all such notices, demands or other communications shall
be concurrently  delivered by the person giving the same to the Trustee,  at the
address specified in the Indenture.

               (d)  SUCCESSORS AND ASSIGNS.  This  Agreement  shall inure to the
benefit of and be binding upon the  successors,  assigns and transferees of each
of the  parties,  including,  without  limitation  and  without  the need for an
express assignment,  subsequent  Holders;  PROVIDED that nothing herein shall be
deemed to permit any  assignment,  transfer or other  disposition of Registrable
Securities  in  violation  of  the  terms  of  the  Purchase  Agreement.  If any
transferee of any Holder shall acquire  Registrable  Securities,  in any manner,
whether by operation of law or otherwise,  such Registrable  Securities shall be
held  subject to all of the terms of this  Agreement,  and by taking and holding
such  Registrable  Securities such person shall be  conclusively  deemed to have
agreed to be bound by and to  perform  all of the terms and  provisions  of this
Agreement and such person shall be entitled to receive the benefits hereof.  The
Placement  Agents (in their  capacity  as the  Placement  Agents)  shall have no
liability or  obligation to the Company or the Trust with respect to any failure
by a  Holder  to  comply  with,  or any  breach  by any  Holder  of,  any of the
obligations of such Holder under this Agreement.

                                       21
<PAGE>

               (e) PURCHASES AND SALES OF  REGISTRABLE  SECURITIES.  Neither the
Company  nor the  Trust  shall,  and  shall  use its best  efforts  to cause its
affiliates (as defined in Rule 405 under the 1933 Act) not to, purchase and then
resell or otherwise transfer any Registrable Securities.

               (f) THIRD PARTY  BENEFICIARY.  The  Holders  shall be third party
beneficiaries  to the  agreements  made  hereunder  between  the Company and the
Trust, on the one hand, and the Placement  Agents,  on the other hand, and shall
have the right to enforce such  agreements  directly to the extent it deems such
enforcement  necessary  or  advisable  to  protect  its  rights or the rights of
Holders hereunder.

               (g) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

               (h) HEADINGS.  The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

               (i)  GOVERNING  LAW.  This  Agreement  shall be  governed  by and
construed in accordance with the internal laws of the State of New York.

               (j)  SEVERABILITY.  In the  event  that  any  one or  more of the
provisions contained herein, or the application thereof in any circumstance,  is
held   invalid,   illegal  or   unenforceable,   the   validity,   legality  and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby

               (k)  JOINT  AND  SEVERAL  OBLIGATIONS.  Anything  herein  to  the
contrary  notwithstanding,   the  representations,   warranties,  covenants  and
agreements  of Viatel and the Trust  contained in this  Agreement  are joint and
several, other than the obligations under Section 5 hereof.

              [THE REST OF THIS PAGE IS INTENTIONALLY LEFT BLANK.]

Act ("REGULATION S").

     The  Placement  Agents and their  direct and indirect  transferees  will be
entitled to the  benefits of a  Registration  Rights  Agreement  relating to the
Notes, to be dated the date hereof, and to be substantially in the form attached
hereto as EXHIBIT A (the "REGISTRATION RIGHTS AGREEMENT").

     In  connection  with the sale of the  Notes to the  Placement  Agents,  the
Company has prepared a preliminary  offering  memorandum issued on April 7, 2000
(the "PRELIMINARY MEMORANDUM") and a final offering memorandum,  dated April 14,

          Adverse Effect (as defined below) on the Company and its  Subsidiaries
          (as defined below), taken as a whole.

          rights generally and subject to general equitable  principles (whether
          considered in a proceeding  in equity or at law) (the  "ENFORCEABILITY
          EXCEPTIONS"),  and (y) be  entitled to the  benefits of the  Indenture
          pursuant  to which such Notes are to be issued,  and the  Registration
          Rights Agreement.

               (f) The  Preliminary  Memorandum  as of the date  hereof does not
          contain and the Final Memorandum,  on the Closing Date and in the form
          used by the Placement  Agents to confirm  sales,  will not contain any
          untrue  statement of a material  fact or omit to state a material fact
          necessary  to  make  the  statements  therein,  in  the  light  of the
          circumstances under which they were made, not misleading,  except that
          the  representations and warranties set forth in this paragraph do not
          apply to statements  in or omissions  from either  Memorandum  (or any
          supplement or amendment  thereto) based upon  information  relating to
          any  Placement  Agent  furnished  to the  Company  in  writing by such
          Placement Agent expressly for use therein.

               (g)  The  execution  and  delivery  by the  Company  of,  and the
          performance by the Company of its obligations  under,  this Agreement,
          the  Indenture,  the  Registration  Rights  Agreement  and  the  Notes
          (collectively, the "TRANSACTION DOCUMENTS") and the issuance, sale and
          delivery  of the  Notes  in  accordance  with  their  terms  will  not
          contravene (i) any provision of applicable  law, (ii) the  certificate
          of  incorporation  or  by-laws  of the  Company,  (iii)  any  material
          agreement or other  instrument  binding upon the Company or any of its
          Subsidiaries,   or  (iv)  any   judgment,   order  or  decree  of  any
          governmental  body,  agency  or  court  having  jurisdiction  over the
          Company or any  Subsidiary,  except  with  respect to clauses  (i) and
          (iii) to the extent that any  contravention  would not have a Material
          Adverse Effect (as defined below) on the Company and its Subsidiaries,
          taken as a whole, and, no consent, approval, authorization,  exemption
          or order of, or qualification or filing with, any governmental body or
          agency  is  required  for  the  performance  by  the  Company  of  its
          obligations under the Transaction  Documents (other than such consent,
          approval,  authorization,  exemption,  order or other action which has
          been  obtained),  except (x) such as may be required by the securities
          or Blue Sky laws of the various  states in  connection  with the offer
          and sale of the Notes,  (y) such as may be  required  by  federal  and
          state securities laws with respect to the Company's  obligations under
          the Registration Rights Agreement and (z) for any consents, approvals,
          authorizations,  orders or qualifications, the failure to obtain which
          would not have a Material Adverse Effect on the ability of the Company
          to perform its obligations under the Transaction Documents.

               (h) The Indenture and the Registration Rights Agreement have been
          duly  authorized  by the Company and, when duly executed and delivered
          by the Company,  will constitute valid and legally binding obligations
          of the Company,  enforceable  against the Company in  accordance  with
          their terms, subject to the Enforceability Exceptions and except  that

          (x)  rights to  indemnification  and  contribution  may be  limited by
          public policy and (y) provisions of the Indenture,  if any,  requiring
          any waiver of stay or extension  laws,  diligent  performance or other
          acts on the part of the Trustee may be unenforceable  under principles
          of public policy.

               (i) The Notes and the Indenture  conform in all material respects
          to the  descriptions  thereof  contained in the Final Memorandum under
          the heading "Description of the Notes."

               (j)   Assuming   the   accuracy   of   the   Placement    Agents'
          representations  contained herein and the Placement Agents' compliance
          with their agreements  hereunder,  it is not necessary to register the
          Notes under the Securities  Act or to qualify the Indenture  under the
          Trust Indenture Act of 1939, as amended.

               (k) There has not occurred any material  adverse  change,  or any
          development  involving a prospective  material adverse change,  in the
          condition,  financial or otherwise,  or in the  earnings,  business or
          operations  (a  "MATERIAL  ADVERSE  EFFECT")  of the  Company  and its
          Subsidiaries,  taken as a whole,  from  that  set  forth in the  Final
          Memorandum,  attached  as EXHIBIT C;  furthermore,  (i) other than the
          transactions  contemplated  hereby,  the Company and its  Subsidiaries
          have not  incurred any material  liability  or  obligation,  direct or
          contingent,  nor  entered  into any  material  transaction  not in the
          ordinary course of business; (ii) the Company has not purchased any of
          its outstanding  capital stock,  nor declared,  paid or otherwise made
          any dividend or  distribution  of any kind on its capital  stock other
          than  ordinary and customary  dividends;  and (iii) there has not been
          any material change in the capital stock, short-term debt or long-term
          debt of the  Company  and its  consolidated  Subsidiaries,  taken as a
          whole, except in each case as described in the Final Memorandum.

               (l) There are no legal or governmental proceedings pending or, to
          the  knowledge of the Company,  threatened to which the Company or any
          of its  Subsidiaries  is or may be a  party,  or to  which  any of the
          properties  of the  Company  or any of its  Subsidiaries  is or may be
          subject other than  proceedings  accurately  described in all material
          respects  in  the  Final  Memorandum  and  proceedings  that  are  not
          reasonably likely to have a Material Adverse Effect on the Company and
          its Subsidiaries,  taken as a whole, or on the power or ability of the
          Company  to  perform  its  obligations  under  any of the  Transaction
          Documents or to consummate the transactions  contemplated by the Final
          Memorandum.

               (m) The Company is not, and after  giving  effect to the offering
          and sale of the Notes,  and the application of the proceeds thereof as
          described in the Final Memorandum under the caption "Use of Proceeds,"
          will not be an  "investment  company"  as such term is  defined in the
          Investment Company Act of 1940, as amended.

               (n)  Neither the  Company  nor any  affiliate  of the Company (as
          defined in Rule 501(b) of  Regulation D under the  Securities  Act, an
          "AFFILIATE") has directly, or through any agent, (i) sold, offered for
          sale,  solicited offers to buy or otherwise  negotiated in respect of,
          any  security (as defined in the  Securities  Act) which is or will be
          integrated  with the sale of the Notes in a manner that would  require
          the registration under the Securities Act of the Notes or (ii) engaged
          in any form of general  solicitation or general  advertising (as those
          terms are used in Regulation D under the Securities Act) in connection
          with the  offering  of the  Notes  in any  manner  involving  a public
          offering within the meaning of Section 4(2) of the Securities Act.

               (o) The Company and its  Subsidiaries  (i) are in compliance with
          any and all  applicable  foreign,  federal,  state and local  laws and
          regulations relating to the protection of human health and safety, the
          environment or hazardous or toxic substances or wastes,  pollutants or
          contaminants  ("ENVIRONMENTAL  LAWS"), (ii) have received all permits,
          licenses  or  other  approvals   required  of  them  under  applicable
          Environmental  Laws to conduct their  respective  businesses and (iii)
          are in  compliance  with all terms and  conditions of any such permit,
          license   or   approval,   except   where  such   noncompliance   with
          Environmental  Laws, failure to receive required permits,  licenses or
          other  approvals or failure to comply with the terms and conditions of
          such  permits,  licenses  or  approvals  would  not,  singly or in the
          aggregate,  have a  Material  Adverse  Effect on the  Company  and its
          Subsidiaries, taken as a whole.

               (p)  There  are  no  costs  and   liabilities   associated   with
          Environmental  Laws  (including,  without  limitation,  any capital or
          operating expenditures required for clean-up, closure of properties or
          compliance with Environmental Laws or any permit, license or approval,
          any related  constraints  on operating  activities  and any  potential
          liabilities to third parties) which would, singly or in the aggregate,
          have a Material  Adverse  Effect on the Company and its  Subsidiaries,
          taken as a whole.

               (q)  The  Notes  satisfy  the  requirements  set  forth  in  Rule
          144A(d)(3) under the Securities Act.

               (r) Except as described in the Final Memorandum,  the Company and
          its  Subsidiaries  (i) have all  necessary  consents,  authorizations,
          approvals, orders, certificates and permits of and from, and have made
          all declarations and filings with, all federal, state, local and other
          governmental,    administrative   or   regulatory   authorities,   all
          self-regulatory  organizations and all courts and other tribunals,  to
          own, lease, license and use their properties and assets and to conduct
          their business in the manner described in the Final Memorandum, except
          to  the   extent   that  the   failure   to  obtain   such   consents,
          authorizations,  approvals,  orders,  certificates  or permits or make
          such  declarations or filings would not have a Material Adverse Effect
          on the Company and its  Subsidiaries,  taken as a whole; and (ii) have
          not received any notice of  proceedings  relating  to  the  violation,
<PAGE>



          revocation   or   modification   of   any   such   license,   consent,
          authorization, approval, order, certificate or permit which, singly or
          in the aggregate, if the subject of an unfavorable decision, ruling or
          finding,  would  reasonably  be  expected  to have a Material  Adverse
          Effect on the Company and its Subsidiaries, taken as a whole.

               (s) The Company  and its  Subsidiaries  have good and  marketable
          title in fee simple to all real property and good and marketable title
          to all  personal  property  owned  by them  which is  material  to the
          business  of the Company and its  Subsidiaries,  taken as a whole,  in
          each case free and clear of all liens, encumbrances and defects except
          (i) such as are reflected in the Company's financial statements or are
          described  in the Final  Memorandum;  (ii)  such as do not  materially
          affect the value of such  property and do not  interfere  with the use
          made and  proposed to be made of such  property by the Company and its
          Subsidiaries;  or (iii) such as do not have a Material  Adverse Effect
          on the Company and its  Subsidiaries,  taken as a whole;  and any real
          property  and  buildings  held  under  lease  by the  Company  and its
          Subsidiaries  are held by them under  valid,  binding and  enforceable
          leases with such  exceptions as are not material and do not materially
          interfere  with the use made and proposed to be made of such  property
          and buildings by the Company and its Subsidiaries, in each case except
          as described in or contemplated by the Final Memorandum and subject to
          the Enforceability Exceptions.

               (t) The  Company  and its  Subsidiaries  own or  possess,  or can
          acquire on reasonable  terms,  all material  patents,  patent  rights,
          licenses,  inventions,  copyrights,  know-how (including trade secrets
          and other unpatented and/or  unpatentable  proprietary or confidential
          information,  systems or  procedures),  trademarks,  service marks and
          trade names currently employed by them in connection with the business
          now  operated  by  them,  and,  except  as  set  forth  in  the  Final
          Memorandum,  neither  the  Company  nor  any of its  Subsidiaries  has
          received  any notice of  infringement  of or  conflict  with  asserted
          rights of others with respect to any of the foregoing which, singly or
          in the aggregate, if the subject of an unfavorable decision, ruling or
          finding,  would be reasonably likely to have a Material Adverse Effect
          on the Company and its Subsidiaries, taken as a whole.

               (u) No material  labor  dispute with the employees of the Company
          or  any  of  its  Subsidiaries  exists,  except  as  described  in  or
          contemplated  by the Final  Memorandum,  or, to the  knowledge  of the
          Company,  is imminent;  and the Company is not aware of any  existing,
          threatened or imminent  labor  disturbance  by the employees of any of
          its  principal  suppliers,  manufacturers  or  contractors  that might
          reasonably  be  expected  to have a  Material  Adverse  Effect  on the
          Company and its Subsidiaries, taken as a whole.

               (v) (i) The Company and its Subsidiaries are insured against such
          losses  and  risks  and in  such  amounts  as the  Company  reasonably
          believes are prudent and customary in the businesses in which they are
          engaged;  (ii)  neither the Company nor any such  Subsidiary  has been
          refused any insurance coverage sought or applied for; and (iii)


                                        6

<PAGE>



          neither the Company nor any such  Subsidiary has any reason to believe
          that it will not be able to renew its existing  insurance  coverage as
          and when such  coverage  expires or to obtain  similar  coverage  from
          similar  insurers as may be  necessary  to continue  its business at a
          cost that would not have a Material  Adverse Effect on the Company and
          its  Subsidiaries,  taken  as a  whole,  except  as  described  in  or
          contemplated by the Final Memorandum.

               (w) The  Company  and  its  Subsidiaries  maintain  a  system  of
          internal   accounting   controls   sufficient  to  provide  reasonable
          assurance  that (i)  transactions  are  executed  in  accordance  with
          management's general or specific authorizations; (ii) transactions are
          recorded as necessary to permit preparation of financial statements in
          conformity  with  generally  accepted  accounting  principles  and  to
          maintain  asset  accountability;  (iii)  access to assets is permitted
          only   in   accordance   with   management's   general   or   specific
          authorization;  and (iv) the  recorded  accountability  for  assets is
          compared  with  the  existing  assets  at  reasonable   intervals  and
          appropriate action is taken with respect to any differences.

     2.  AGREEMENTS TO SELL AND PURCHASE.  The Company  hereby agrees to sell to
the several  Placement  Agents,  and each Placement  Agent upon the basis of the
representations  and warranties herein contained,  but subject to the conditions
hereinafter  stated,  agrees,  severally  and not jointly,  to purchase from the

     The Company hereby agrees that, without the prior written consent of Morgan

of any  debt  of the  Company  or  warrants  to  purchase  debt  of the  Company
substantially  similar to the Notes (other than the sale of the Notes under this
Agreement).

the  Placement  Agents  will  make an  offering  of the Notes  purchased  by the

               any  notice  have  been  given  of  any   intended  or  potential
               downgrading or of any review for a possible  change that does not
               indicate the  direction of the  possible  change,  other than any
               notice which shall already have been given as of the date hereof,
               in the rating  accorded  to the  Company or any of the  Company's

the Placement  Agents  contained in this Agreement,  the Company  covenants with
each Placement Agent as follows:

               (a) To use its best efforts to furnish to each Placement Agent in
          New York City,  without charge,  prior to 9:00 a.m. New York City time

          many copies of the Final  Memorandum,  any  supplements and amendments
          thereto and any documents incorporated by reference therein as you may
          reasonably request.

               (b) Before amending or  supplementing  the Final  Memorandum,  to
          furnish to each Placement Agent a copy of each such proposed amendment
          or supplement and not to use any such proposed amendment or supplement

          which consent shall not be unreasonably withheld or delayed.

               (c) If, during such period after the date hereof and prior to the
          date on which all of the Notes  shall have been sold by the  Placement
          Agents,  any event shall occur or condition exist as a result of which
          it is necessary to amend or supplement  the Final  Memorandum in order

          to amend or supplement the Final  Memorandum to comply with applicable
          law,  forthwith  to prepare and furnish,  at its own  expense,  to the
          Placement  Agents,  either  amendments  or  supplements  to the  Final
          Memorandum  so that  the  statements  in the  Final  Memorandum  as so
          amended or  supplemented  will not, in the light of the  circumstances
          when the Final  Memorandum is delivered to a purchaser,  be misleading
          or so that the Final Memorandum,  as so amended or supplemented,  will
          comply with applicable law.

               (d) To endeavor to qualify the Notes for offer and sale under the
          securities  or Blue Sky laws of such  jurisdictions  as the  Placement
          Agents shall reasonably  request;  PROVIDED THAT in no event shall the
          Company be obligated to qualify to do business in any  jurisdiction in
          which it is not now so  qualified  or to take any action  which  would
          subject it to taxation in any  jurisdiction  in which it is not now so
          subject or to service  or process in suits,  other than those  arising
          out of the offering or sale of the Notes in any  jurisdiction in which
          it is not now so subject.

          Agreement are  consummated or this Agreement is terminated,  to pay or

                  (a) The Company  agrees to indemnify  and hold  harmless  each
Placement  Agent,  and each person,  if any, who controls such  Placement  Agent
within the meaning of either  Section 15 of the  Securities Act or Section 20 of
the  Exchange  Act from and  against  any and all  losses,  claims,  damages and
liabilities  (including,   without  limitation,  any  legal  or  other  expenses
reasonably  incurred in  connection  with  defending or  investigating  any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in each  Memorandum (as amended or  supplemented  if the
Company shall have furnished any amendments or supplements  thereto),  or caused
by any omission or alleged  omission to state therein a material fact  necessary
to make the statements  therein,  in the light of the circumstances  under which
they were made, not misleading;  PROVIDED, HOWEVER, that the Company will not be
liable in any such case to the  extent,  but only to the  extent,  that any such
losses,  claims,  damages or liabilities are caused by any such untrue statement
or omission or alleged  untrue  statement  or  omission  based upon  information
relating  to the  Placement  Agents  furnished  to the Company in writing by the
Placement Agents expressly for use therein.

                  (b) Each Placement Agent agrees, severally and not jointly, to
indemnify and hold harmless the Company,  its  directors,  its officers and each
person, if any, who controls the Company within the meaning of either 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 such Placement Agent, but only with
reference  to  information  relating to such  Placement  Agent  furnished to the
Company  in  writing  by  such  Placement  Agent  expressly  for  use in  either
Memorandum or any amendments or supplements thereto.

                  (c)  In  case  any  proceeding   (including  any  governmental
investigation)  shall be  instituted  involving  any  person in respect of which
indemnity  may be sought  pursuant to any  provision  of Section 8(a) or Section
8(b),  such person (the  "INDEMNIFIED  PARTY") shall promptly  notify the person
against whom such indemnity may be sought (the "INDEMNIFYING  PARTY") in writing
(but the  failure to so notify an  indemnifying  party shall not relieve it from
any liability  which it may have under this Section 8, except to the extent that
it has been  prejudiced  in any material  respect by such  failure,  or from any
liability it may otherwise have) and the indemnifying party, upon request of the
indemnified  party,   shall  retain  counsel  reasonably   satisfactory  to  the
indemnified  party  to  represent  the  indemnified  party  and any  others  the
indemnifying  party may designate in such  proceeding and shall pay the fees and
disbursements  of  such  counsel  related  to  such  proceeding.   In  any  such
proceeding,  any  indemnified  party  shall  have the  right to  retain  its own
counsel,  but the fees and expenses of such  counsel  shall be at the expense of
such  indemnified  party unless (i) the  indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall  not,  in  respect  of the  legal  expenses  of any  indemnified  party in
connection with any proceeding or related  proceedings in the same jurisdiction,
be liable for the  reasonable  fees and expenses of more than one separate  firm
(in addition to any local counsel) for all such indemnified parties and that all
such fees and expenses shall be reimbursed as they are incurred. Such firm shall
be designated in writing by Morgan  Stanley & Co.  International  Limited in the
case of parties  indemnified  pursuant to Section 8(a) and by the Company in the
case of parties  indemnified  pursuant to Section 8(b). The  indemnifying  party
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  party  agrees to indemnify  the
indemnified  party  from and  against  any loss or  liability  by reason of such
settlement or judgment.  Notwithstanding the foregoing sentence,  if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this  paragraph,  the  indemnifying  party 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  party of the  aforesaid  request  and (ii)  such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such  settlement.  No indemnifying  party
shall, without the prior written consent of the indemnified

                                       15

<PAGE>

party, which consent may not be unreasonably withheld,  effect any settlement of
any pending or threatened  proceeding in respect of which any indemnified  party
is or could have been a party and  indemnity  could have been  sought  hereunder
(whether or not any  indemnified  party is an actual or potential  party to such
proceeding)  by such  indemnified  party,  unless  such  settlement  includes an
unconditional  release of such  indemnified  party from all  liability on claims
that are the subject matter of such proceeding.

                  (d) To the  extent  the  indemnification  provided  for in any
provision of Section 8(a) or Section 8(b) is unavailable to an indemnified party
or  insufficient  in  respect of any  losses,  claims,  damages  or  liabilities
referred to therein, then each indemnifying party under such section, in lieu of
indemnifying such indemnified  party thereunder,  shall contribute to the amount
paid or payable by such  indemnified  party as a result of such losses,  claims,
damages or liabilities  (i) in such  proportion as is appropriate to reflect the
relative  benefits  received by the Company,  on the one hand, and the Placement
Agents,  on the other hand,  from the  offering  of such  Notes,  or (ii) if the
allocation  provided by clause 8(d)(i) above is not permitted by applicable law,
in such  proportion as is appropriate to reflect not only the relative  benefits
referred to in clause  8(d)(i) above but also the relative  fault of the Company
and the Placement  Agents in connection  with the  statements or omissions  that
resulted in such losses,  claims,  damages or liabilities,  as well as any other
relevant  equitable  considerations.  The  relative  benefits  received  by  the
Company,  on the one hand,  and the  Placement  Agents,  on the other  hand,  in
connection  with the  offering  of the  Notes  shall be deemed to be in the same
respective  proportions  as the net proceeds from the offering of the Notes (net
of discounts and  commissions  but before  deducting  expenses)  received by the
Company and the total discounts and commissions received by the Placement Agents
in respect  thereof  bear to the  aggregate  offering  price of the  Notes.  The
relative fault of the Company, on the one hand, and the Placement Agents, on the
other hand, 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
or the Placement Agents and the parties' relative intent,  knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission.
The Placement  Agents'  respective  obligations  to contribute  pursuant to this
Section 8 are several in proportion to the respective  principal amount of Notes
they have purchased hereunder, and not joint.

                  (e) The Company and the  Placement  Agents agree that it would
not be just or  equitable  if  contribution  pursuant  to  this  Section  8 were
determined by PRO RATA allocation or by any other method of allocation that does
not take account of the  equitable  considerations  referred to in Section 8(d).
The amount  paid or payable by an  indemnified  party as a result of the losses,
claims,  damages  and  liabilities  referred  to in Section  8(d) above shall be
deemed to include,  subject to the  limitations  set forth  above,  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or  defending  any such  action  or  claim.  Notwithstanding  the
provisions  of this  Section 8, the  Placement  Agents  shall not be required to
contribute  any amount in excess of the amount by which the total price at which
the Notes resold

                                       16

<PAGE>

by it in the initial  placement of such Notes were offered to investors  exceeds
the amount of any damages that such Placement  Agent 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 remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies  which may  otherwise be available to
any indemnified party at law or in equity.

                  (f) The indemnity  and  contribution  provisions  contained in
this Section 8 and the  representations,  warranties and other statements of the
Company contained in this Agreement shall remain operative and in full force and
effect   regardless  of  (i)  any  termination  of  this  Agreement,   (ii)  any
investigation  made  by or on  behalf  of any  Placement  Agent  or  any  person
controlling any Placement Agent or by or on behalf of the Company, or any of its
officers  or  directors  or  any  person  controlling  the  Company,  and  (iii)
acceptance of and payment for any of the Notes.

     9.  TERMINATION.  This Agreement  shall be subject to termination by notice
given by the  Placement  Agents to the Company,  if (a) after the  execution and
delivery of this  Agreement and prior to the Closing Date (i) trading  generally
shall have been  suspended or  materially  limited on or by, as the case may be,
any of the New York Stock Exchange,  the American Stock  Exchange,  the National
Association of Securities Dealers,  Inc., the Chicago Board of Options Exchange,
the Chicago  Mercantile  Exchange or the Chicago Board of Trade, (ii) trading of
any  securities of the Company  shall have been  suspended on any exchange or in
any  over-the-counter  market,  (iii) a general moratorium on commercial banking
activities  in New York shall have been  declared by either  Federal or New York
State  authorities  or (iv) there shall have occurred any outbreak or escalation
of  hostilities  or any change in  financial  markets or any  calamity or crisis
that,  in your  judgment,  is material and adverse and (b) in the case of any of
the events  specified in clauses  9(a)(i) through  9(a)(iv)  above,  such event,
singly  or  together  with any other  such  event,  makes it, in your  judgment,
impracticable to market the Notes on the terms and in the manner contemplated in
the Final Memorandum.

     10. EFFECTIVENESS; DEFAULTING PLACEMENT AGENTS. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date, any one or more of the Placement Agents shall fail
or refuse to purchase Notes that it or they have agreed to purchase hereunder on
such date,  and the aggregate  principal  amount of Notes which such  defaulting
Placement Agent or Placement  Agents agreed but failed or refused to purchase is
not  more  than  one-tenth  of the  aggregate  principal  amount  of Notes to be
purchased on such date, the other Placement Agents shall be obligated  severally
in the proportions  that the principal  amount of Notes set forth opposite their
respective names in Schedule I bears to the aggregate  principal amount of Notes
set forth opposite the names of all such non-defaulting  Placement Agents, or in
such other  proportions  as you may  specify,  to purchase  the Notes which such
defaulting Placement Agent or Placement

                                       17

<PAGE>

Agents  agreed but failed or refused to purchase on such date;  PROVIDED that in
no event shall the principal amount of Notes that any Placement Agent has agreed
to purchase pursuant to this Agreement be increased  pursuant to this Section 10
by an amount in excess of one-ninth of such  principal  amount of Notes  without
the  written  consent of such  Placement  Agent.  If, on the Closing  Date,  any
Placement Agent or Placement Agents shall fail or refuse to purchase Notes which
it or they have  agreed to  purchase  hereunder  on such date and the  aggregate
principal amount of Notes with respect to which such default occurs is more than
one-tenth  of the  aggregate  principal  amount of Notes to be purchased on such
date, and  arrangements  satisfactory to you and the Company for the purchase of
such Notes are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Placement Agent or
of the Company.  In any such case either you or the Company shall have the right
to postpone  the Closing  Date,  but in no event for longer than seven days,  in
order that the required changes, if any, in the Final Memorandum or in any other
documents or arrangements may be effected. Any action taken under this paragraph
shall not relieve any  defaulting  Placement  Agent from liability in respect of
any default of such Placement Agent under this Agreement.

     If this Agreement  shall be terminated by the Placement  Agents,  or any of
them,  because of any  failure  or refusal on the part of the  Company to comply
with the terms or to fulfill any of the conditions of this Agreement,  or if for
any reason the  Company  shall be unable to perform its  obligations  under this
Agreement  (other  than by reason of a breach  of this  Agreement  by any of the
Placement  Agents),  the Company  will  reimburse  the  Placement  Agent or such
Placement   Agents  as  have  so  terminated  this  Agreement  with  respect  to
themselves,  severally,  for all out-of-pocket  expenses (including the fees and
disbursements  of its counsel)  reasonably  incurred by such Placement Agents in
connection with this Agreement or the offering contemplated hereunder.

     11. NOTICES. All notices and other communications  required or permitted to
be given  under this  Agreement  shall be in writing and shall be deemed to have

<PAGE>

                                                                       EXHIBIT D

                               FORM OF OPINION OF
                            KELLEY DRYE & WARREN LLP

                  Pursuant to Section 5(d) of the  Placement  Agreement,  Kelley
Drye & Warren LLP shall deliver an opinion to the effect that:

               (A)  the  Company  has  been  duly  incorporated  and is  validly
          existing as a corporation in good standing under the laws of the State
          of Delaware with full corporate  power and corporate  authority to own
          its  properties  and to conduct its business as described in the Final
          Memorandum  (references  herein to the Final Memorandum being taken to
          mean the same, as amended or  supplemented),  and is duly qualified to
          transact business as a foreign  corporation and is in good standing in
          each  jurisdiction  in  which  the  conduct  of  its  business  or its
          ownership or leasing of property requires such  qualification,  except
          to the  extent  that  the  failure  to be so  qualified  or be in good
          standing  would not have a Material  Adverse Effect on the Company and
          its Subsidiaries, taken as a whole;

               (B) the Company has all necessary  corporate power and authority,
          and has taken all  necessary  corporate  action,  to duly and  validly
          authorize the issuance and sale of the Notes, the execution,  delivery
          and  performance  of,  and  the   consummation  of  the   transactions
          contemplated  in, this Agreement,  the Indenture and the  Registration
          Rights  Agreement (such documents shall,  hereinafter,  be referred to
          collectively  as, the  "Transaction  Documents" and such  transactions
          shall, hereinafter,  be referred to collectively as, the "Contemplated
          Transactions"),  and no other corporate proceedings by the Company are
          necessary to authorize  the  execution  and delivery by the Company of
          the  Transaction  Documents or the  performance  by the Company of the
          Contemplated Transactions;

               (C) the Placement  Agreement has been duly  authorized,  executed
          and delivered by the Company;

               (D) the Notes have been duly authorized,  executed, and issued by
          the Company and, assuming due authentication thereof by the Trustee in
          accordance  with the  terms of the  Indenture  and  upon  payment  and
          delivery in accordance with the terms of the Placement Agreement, will
          (x) constitute  valid and legally  binding  obligations of the Company
          enforceable against the Company in accordance with their terms, except
          as the enforceability thereof may be limited by applicable bankruptcy,
          insolvency,  fraudulent  conveyance,  reorganization,  moratorium  and
          other similar laws affecting creditors' rights generally and equitable
          principles  (whether  considered  in a proceeding in equity or at law)
          and  (y)  be  entitled  to  the  benefits  of the  Indenture  and  the
          Registration Rights Agreement;


<PAGE>



               (E) each of the Indenture and the  Registration  Rights Agreement
          has been duly authorized,  executed and delivered by the Company, and,
          assuming the due  authorization,  execution  and delivery by the other
          parties thereto, constitutes a valid and legally binding obligation of
          the Company,  enforceable  against the Company in accordance  with its
          terms  except as (x) the  enforceability  thereof  may be  limited  by
          bankruptcy,   insolvency,   fraudulent   conveyance,   reorganization,
          moratorium  and other  similar  state or federal  laws  affecting  the
          rights and  remedies of  creditors  generally  and  general  equitable
          principles  (whether  considered in a proceeding in equity or at law),
          (y)  rights to  indemnification  and  contribution  may be  limited by
          public policy and (z) provisions of the Indenture,  if any,  requiring
          any waiver of stay or extension  laws,  diligent  performance or other
          acts on the part of the Trustee may be unenforceable  under principles
          of public policy;

               (F)  neither  the  execution,  delivery  nor  performance  by the
          Company of its  obligations  under the  Transaction  Documents nor the
          issuance,  sale and  delivery  of the Notes in  accordance  with their
          terms  will  contravene  (i) the DGCL or any U.S.  federal or New York
          State law, statute,  ordinance,  rule, regulation,  judgment, order or
          decree  applicable to the Company or any of its assets or  properties,
          whether owned or leased,  (ii) the  Certificate  of  Incorporation  or
          By-laws  of the  Company,  (iii)  any  agreement  or other  instrument
          binding upon the Company or any of its  Subsidiaries  that is material
          to the Company  and its  Subsidiaries,  taken as a whole,  or (iv) any
          judgment,  order or decree of any governmental  body,  agency or court
          having jurisdiction over the Company or any Subsidiary, except, in the
          case of clauses (i),  (iii) and (iv),  for such  contraventions  which
          would  not have a  Material  Adverse  Effect  on the  Company  and its
          Subsidiaries,  taken as a whole and,  except as may be required  under
          applicable  state  securities  or Blue Sky laws,  and  except  for the
          filing  of  registration  statements  under  the  Securities  Act  and
          qualification  of the  Indenture  under  the  Trust  Indenture  Act in
          connection  with  the  Registration  Rights  Agreement,   no  consent,
          approval,  authorization or order of, or qualification  with, any U.S.
          federal or New York or Delaware state  governmental  body or agency is
          required for the performance by the Company of its  obligations  under
          the Transaction Documents;

               (G) to the best  knowledge of such counsel,  there is no legal or
          governmental  proceeding,  now  pending  or  threatened,  to which the
          Company or any of its  Subsidiaries  is a party or to which any of the
          properties  of the  Company  or any of its  Subsidiaries  is or may be
          subject that is required to be disclosed in the Final  Memorandum  and
          that is not so  disclosed,  or which could  reasonably  be expected to
          have a Material  Adverse  Effect on the Company and its  Subsidiaries,
          taken as a whole,  or on the  ability of the  Company  to perform  its
          obligations  under the  Transaction  Documents  or to  consummate  the
          transactions contemplated by the Final Memorandum;

               (H) the Company is not, and after  giving  effect to the offering
          and sale of the Notes and the  application of the proceeds  thereof as
          described in the Final Memorandum,

                                       TO

                    FORM OF KELLEY DRYE & WARREN LLP OPINION


     In the course of the preparation by the Company of the Final Memorandum, we
have participated in conferences with officers, directors and representatives of
the  Company,   its   independent   auditors,   officers,   directors  and  your
representatives  and  representatives  of your counsel at which  conferences the
contents of the Final Memorandum and related matters were discussed. Although we
have not  independently  verified the accuracy or completeness  of, or otherwise
verified the statements  made in the Final  Memorandum  (other than as expressly
provided  above),  nothing has come to our attention  that has led us to believe
that the  Final  Memorandum,  as of its date or the date  hereof,  contained  an
untrue  statement  of a  material  fact or  omitted  to  state a  material  fact
necessary  in  order  the  make  the  statements  therein,  in the  light of the
circumstances  under which they were made, not misleading.  Notwithstanding  the
foregoing,  we are not expressing any belief as to the financial  statements and
supporting  notes and schedules and other  financial data contained in the Final
Memorandum.

                      FORM OF FOREIGN LOCAL COUNSEL OPINION


     (A)  [________]  (the  "Company")  has been duly  incorporated,  is validly
existing as a company  under the laws of [Name of  Country],  has the  corporate
power and authority to own its property and to conduct its business as described
in the Offering  Memorandum  of Viatel,  Inc.  dated April ___, 2000 (the "Final
Memorandum") and is duly qualified to transact  business in each jurisdiction in
which the  conduct of its  business  or its  ownership  or  leasing of  property
requires  such  qualification  (except to the extent  that the  failure to be so
qualified  would not in our view have a Material  Adverse  Effect on the Company
and its subsidiaries taken as a whole).

     (B) The Company has no subsidiaries.

     (C) The Company has all materially necessary certificates, orders, permits,
licenses,  authorizations,  consents and approvals of and from, and has made all
declarations  and  filings  with  all  relevant  governmental  authorities,  all
self-regulatory  organizations  and all relevant  courts and tribunals,  to own,
lease,  license and use its properties and assets and to conduct its business in
the manner described in the Final Memorandum, and, to the best of our knowledge,
after due  inquiry  has not  received  any  notice of  proceedings  relating  to
revocation or modification of any such certificates,  orders, permits, licenses,
authorizations, consents or approvals, nor is the Company in violation of, or in
default under, any federal,  state, local, national or regional law, regulation,
rule, decree,  order or judgment applicable to the Company, the effect of which,
singly  or in  the  aggregate,  would  have a  material  adverse  effect  on the
prospects,  condition,  financial or otherwise, or in the earnings,  business or
operations  of  the  Company,  except  as  described  herein  or  in  the  Final
Memorandum.

     (D) The statements in the Final Memorandum  under the caption  "Business --
[_______]"  are  accurate in all  material  respects  and fairly  summarize  all
matters referred to therein.

     (E) There are no  restrictions  (legal,  contractual  or  otherwise) on the
ability of the  Company to declare  and pay any  dividend or make any payment or
transfer of property or assets to its stockholders other than those described in
the Final Memorandum and such  restrictions as would not have a material adverse
effect on the prospects,  condition, financial or otherwise, or in the earnings,
business or  operations  of the Company and such  descriptions,  if any,  fairly
summarize such restrictions.

                     FORM OF U.S. REGULATORY COUNSEL OPINION


     Pursuant to Section 5(f) of the  Placement  Agreement,  Morrison & Foerster
LLP, regulatory counsel for the Company,  shall furnish an opinion to the effect
that:

                  (A) (1) the execution and delivery of the Placement  Agreement
         by the Company and the  consummation of the  transactions  contemplated
         thereby do not violate (i) the federal  Communications  Act of 1934, as
         amended,  and  the   Telecommunications  Act  of  1996,  any  rules  or
         regulations of the Federal Communications Commission ("FCC") applicable
         to the Company (collectively, the "Communications Act"), (ii) any state
         telecommunications  law, rules or regulations  ("State Law") applicable
         to the Company, and (iii) to the best of such counsel's knowledge,  any
         decree from any court, and (2) no consent,  approval,  authorization or
         order of or  filing  with  the FCC or any  state  authority  overseeing
         telecommunications  matters  ("State  Authority")  is necessary for the
         execution  and delivery of the  Placement  Agreement by the Company and
         except  to the  extent  that  the  failure  to  obtain  such  consents,
         approvals,  authorizations or orders or to make filings with the FCC or
         any State Authority would not, individually or in the aggregate, have a
         material  adverse  effect on the  prospects,  condition  (financial  or
         otherwise)  or on the  earnings,  business or operations of the Company
         and the  subsidiaries  listed in Schedule B to the  Purchase  Agreement
         (the "Subsidiaries") taken as a whole;

                  (B) except as  indicated  in this  paragraph B, to the best of
         our  knowledge,  (1) the  Company  and its  Subsidiaries  have made all
         reports  and  filings,  and paid all fees,  required by the FCC and the
         State  Authorities,   and  have  all  certificates,   orders,  permits,
         licenses, authorizations,  consents and approvals of and from, and have
         made  all  filings  and  registrations,  with  the FCC  and  the  State
         Authorities necessary to own, lease, license and use its properties and
         assets and to conduct its respective  business in the manner  described
         in the Final Memorandum,  except for those filings, fees, and approvals
         the failure to obtain or file of which would not have material  adverse
         effect on the financial  condition,  or on the earnings,  business,  or
         operations of the Company and its  Subsidiaries,  taken as a whole; (2)
         has not received any notice of  proceedings  relating to the violation,
         revocation or modification of any such certificates,  orders,  permits,
         licenses,  authorizations,  consents or approvals, or the qualification
         or rejection of any such filing or  registration,  the effect of which,
         singly or in the aggregate, would have a material adverse effect on the
         prospects,  condition,  financial  or  otherwise,  or in the  earnings,
         business  or  operations  of the  Company,  taken as a  whole;  and (3)
         neither the  Company nor its  Subsidiaries  is in  violation  of, or in
         default  under,  the  Communications  Act or State  Law,  the effect of
         which, singly or in the aggregate, would have a material adverse effect
         on  the  prospects,  condition,  financial  or  otherwise,  or  in  the
         earnings,  business or operations of the Company and its  Subsidiaries,
         taken as a whole;


<PAGE>


                  (C) to the best of such counsel's  knowledge after due inquiry
         (i) no  adverse  judgment,  decree  or  order  of the FCC or any  State
         Authority has been issued against the Company or its  Subsidiaries  and
         (ii) no  litigation,  proceeding,  inquiry  or  investigation  has been
         commenced or threatened against the Company or its Subsidiaries  before
         or by the FCC or any State Authority which, if decided adversely to the
         interests  of the  Company  or its  Subsidiaries  would have a material
         adverse effect on the Company and its  Subsidiaries,  taken as a whole;
         and

                  (D) the statements in the Final  Memorandum under the captions
         "Risk Factors -- Competition," "Risk Factors -- Substantial  Government

         telecommunications regulation referred to therein, fairly summarize the
         matters referred to therein.

Agents  not more than an  additional  600,000  of its 7 3/4%  Trust  Convertible
Preferred  Securities,  liquidation  preference  $50 per  convertible  preferred
security (the "ADDITIONAL SECURITIES"),  if and to the extent that the Placement
Agents shall have  determined to exercise the right to purchase such  additional
securities granted to the several Placement Agents in Section 2 hereof. The Firm

to as the "CONVERTIBLE PREFERRED SECURITIES."

                  The Convertible  Preferred  Securities will be guaranteed (the

(the "GUARANTEE  TRUSTEE"),  and will be convertible  into the common stock, par
value $0.01 per share, of Viatel ("VIATEL COMMON STOCK" or the "COMMON  STOCK").
The  Trust  will use the  proceeds  from the sale of the  Convertible  Preferred
Securities  and the sale of the Trust Common  Securities  (as defined  below) to
purchase from the Company $154,639,175  aggregate principal amount of its 7 3/4%

beneficial interests in the assets of the Trust (the "TRUST COMMON SECURITIES"),
which the Company will purchase from the Trust  pursuant to a Common  Securities
Purchase  Agreement  to be dated as of April 12,  2000 (the  "COMMON  SECURITIES
PURCHASE  AGREEMENT" and, together with the Debenture  Purchase  Agreement,  the
"PURCHASE  AGREEMENTS")  between  the Company  and the Trust.  The Trust  Common
Securities  will be  guaranteed  by the  Company to the extent  provided  in the
Common  Securities  Guarantee  Agreement  to be dated as of April 12,  2000 (the
"COMMON SECURITIES  GUARANTEE AGREEMENT" and, together with Preferred Securities
Guarantee  Agreement,  the  "GUARANTEE  AGREEMENTS")  to be entered  into by the
Company.

                  The Trust has been formed  under  Delaware  law  pursuant to a
Declaration  of Trust,  dated as of March 31, 2000, as amended by an Amended and
Restated  Declaration  of Trust to be dated as of April 12,  2000 (as so amended
and restated,  the "DECLARATION"),  executed by the Company, as sponsor,  and by
the trustees of the Trust (the "VFT  TRUSTEE"),  all of whom have been appointed
by the Company as holder of one hundred percent of the Trust Common  Securities.
A majority of the VFT  Trustees  (the  "REGULAR  TRUSTEES")  are persons who are
employees or officers of the Company.  One VFT Trustee, The Bank of New York, is
unaffiliated  with the  Company  and shall  act as  institutional  trustee  (the
"INSTITUTIONAL  TRUSTEE") and as indenture trustee under the Declaration for the
purposes of the Trust  Indenture Act of 1939,  as amended (the "TRUST  INDENTURE
ACT").  The  Bank of New  York  (Delaware)  will act as  Delaware  trustee  (the
"DELAWARE TRUSTEE") under the Declaration.

                  The Company and the Trust will be  obligated  to file with the
Securities  and  Exchange  Commission  (the  "COMMISSION"),  and  to  use  their
reasonable  best efforts to cause the Commission to declare  effective,  a shelf
registration  statement  covering  certain resales of the Convertible  Preferred
Securities,  Convertible  Debentures,  the  Guarantee  and Viatel  Common  Stock
pursuant to the  Registration  Rights  Agreement to be dated as of April 6, 2000
(the  "REGISTRATION  RIGHTS  AGREEMENT")  among the Trust,  the  Company and the
Placement  Agents and to be substantially in the form attached hereto as EXHIBIT
A.

                  The Declaration,  the Convertible  Preferred  Securities,  the
Trust Common Securities, the Indenture, the Convertible Debentures, the Purchase
Agreements, the Guarantee Agreements, the Registration Rights Agreement and this
Agreement are hereinafter called, collectively, the "OPERATIVE INSTRUMENTS."

                  The Convertible  Preferred  Securities will be offered without
being  registered  under the Securities Act of 1933, as amended (the "SECURITIES
ACT"),  to "qualified  institutional  buyers" (as defined in Rule 144A under the
Securities Act) in compliance with the exemption from  registration  provided by
Rule 144A under the Securities Act.

                  In  connection  with  the  sale of the  Convertible  Preferred
Securities, the Company has prepared a preliminary Offering Memorandum issued on
March 31, 2000 (the  "PRELIMINARY  MEMORANDUM") and a final Offering  Memorandum
dated April 6, 2000 (the "FINAL

         requires such  qualification,  except to the extent that the failure to
         be so  qualified  or be in good  standing  would  not  have a  Material
         Adverse Effect (as defined  below) on the Company and its  Subsidiaries
         (as defined below), taken as a whole.

                  (b) Each  subsidiary  of the  Company  is listed on  EXHIBIT B

         be so  qualified  or be in good  standing  would  not  have a  Material
         Adverse  Effect  (defined  below) on the Company and the  Subsidiaries,

         there has not been any material change in the capital stock, short-term
         debt  or   long-term   debt  of  the  Company   and  its   consolidated
         Subsidiaries, taken as a whole, except in each case as described in the
         Final Memorandum.

                  (v) There are no legal or governmental proceedings pending or,
         to the knowledge of the Trust and the Company,  threatened to which the
         Trust or the Company or any of its  Subsidiaries  is or may be a party,
         or to which any of the properties of the Trust or the Company or any of
         its Subsidiaries is or may be subject other than proceedings accurately
         described  in  all  material  respects  in  the  Final  Memorandum  and
         proceedings  that are not reasonably  likely to have a Material Adverse
         Effect on Company  and its  Subsidiaries,  taken as a whole,  or on the
         power or ability of the Trust or the Company to perform its  respective
         obligations under any of the Operative Instruments or to consummate the
         transactions contemplated by the Final Memorandum.

                  (w) Each of the Trust and the Company is not, and after giving
         effect to the issuance of the Convertible  Preferred Securities and the
         Convertible  Debentures,  and the  application  of the  proceeds of the
         Convertible  Preferred  Securities as described in the Final Memorandum
         under  the  caption  "Use  of  Proceeds,"  will  not be an  "investment
         company" as such term is defined in the Investment Company Act of 1940,
         as amended.

                  (x) Neither the Company nor any  affiliate  of the Company (as
         defined in Rule 501(b) of  Regulation  D under the  Securities  Act, an
         "AFFILIATE") has directly,  or through any agent, (i) sold, offered for
         sale,  solicited  offers to buy or otherwise  negotiated in respect of,
         any  security  (as defined in the  Securities  Act) which is or will be
         integrated  with the sale of any of the Offered  Securities in a manner
         that would require the registration  under the Securities Act of any of
         the  Offered  Securities  or  (ii)  engaged  in  any  form  of  general
         solicitation  or  general  advertising  (as  those  terms  are  used in
         Regulation D under the Securities  Act) in connection with the offering
         of any of the  Offered  Securities  in any  manner  involving  a public
         offering within the meaning of Section 4(2) of the Securities Act.

                  (y) The Company  and its  Subsidiaries  (i) are in  compliance
         with any and all applicable foreign,  federal, state and local laws and
         regulations  relating to the protection of human health and safety, the
         environment or hazardous or toxic  substances or wastes,  pollutants or
         contaminants  ("ENVIRONMENTAL  LAWS"),  (ii) have received all permits,
         licenses  or  other  approvals   required  of  them  under   applicable
         Environmental Laws to conduct their respective businesses and (iii) are
         in compliance with all terms and conditions of any such permit, license
         or approval,  except where such noncompliance with Environmental  Laws,
         failure to receive  required  permits,  licenses or other  approvals or
         failure  to  comply  with the  terms and  conditions  of such  permits,
         licenses or approvals  would not,  singly or in the  aggregate,  have a
         Material Adverse Effect on the Company and its Subsidiaries, taken as a
         whole.

                  (z)  There  are  no  costs  and  liabilities  associated  with
         Environmental  Laws  (including,  without  limitation,  any  capital or
         operating expenditures required for clean-up,  closure of properties or
         compliance with Environmental Laws or any permit,  license or approval,
         any related  constraints  on  operating  activities  and any  potential
         liabilities to third parties) which would,  singly or in the aggregate,
         have a Material  Adverse  Effect on the Company  and its  Subsidiaries,
         taken as a whole.

                  (aa) The Convertible  Preferred Securities and the Convertible
         Debentures  satisfy the requirements set forth in Rule 144A(d)(3) under
         the Securities Act.

                  (bb) Except as described in the Final Memorandum,  the Company
         and its Subsidiaries (i) have all necessary  consents,  authorizations,
         approvals,  orders, certificates and permits of and from, and have made
         all declarations and filings with, all federal,  state, local and other
         governmental, administrative or regulatory authorities, all

         self-regulatory  organizations  and all courts and other tribunals,  to
         own, lease,  license and use their properties and assets and to conduct
         their business in the manner described in the Final Memorandum,  except
         to the extent that the failure to obtain such consents, authorizations,
         approvals, orders, certificates or permits or make such declarations or
         filings would not have a Material Adverse Effect on the Company and its
         Subsidiaries,  taken as a whole;  and (ii) have not received any notice
         of proceedings relating to the violation, revocation or modification of
         any such license, consent, authorization,  approval, order, certificate
         or permit  which,  singly or in the  aggregate,  if the  subject  of an
         unfavorable decision,  ruling or finding,  would reasonably be expected
         to have a Material Adverse Effect on the Company and its  Subsidiaries,
         taken as a whole.

                  (cc) The Company and its Subsidiaries have good and marketable
         title in fee simple to all real property and good and marketable  title
         to all  personal  property  owned  by them  which  is  material  to the
         business of the Company and its Subsidiaries, taken as a whole, in each
         case free and clear of all liens,  encumbrances  and defects except (i)
         such as are  reflected in the  Company's  financial  statements  or are
         described  in the  Final  Memorandum;  (ii)  such as do not  materially
         affect the value of such  property  and do not  interfere  with the use
         made and  proposed  to be made of such  property by the Company and its
         Subsidiaries; or (iii) such as do not have a Material Adverse Effect on
         the  Company  and its  Subsidiaries,  taken  as a  whole;  and any real
         property  and  buildings  held  under  lease  by the  Company  and  its
         Subsidiaries  are held by them under  valid,  binding  and  enforceable
         leases with such  exceptions as are not material and do not  materially
         interfere  with the use made and  proposed to be made of such  property
         and buildings by the Company and its Subsidiaries,  in each case except
         as described in or contemplated by the Final  Memorandum and subject to
         the Enforceability Exceptions.

                  (dd) The Company and its Subsidiaries  own or possess,  or can
         acquire on  reasonable  terms,  all material  patents,  patent  rights,
         licenses, inventions, copyrights, know-how (including trade secrets and
         other  unpatented  and/or  unpatentable   proprietary  or  confidential
         information,  systems or  procedures),  trademarks,  service  marks and
         trade names currently  employed by them in connection with the business
         now operated by them, and, except as set forth in the Final Memorandum,
         neither the Company nor any of its Subsidiaries has received any notice
         of  infringement  of or conflict  with  asserted  rights of others with
         respect to any of the foregoing which,  singly or in the aggregate,  if
         the subject of an  unfavorable  decision,  ruling or finding,  would be
         reasonably  likely to have a Material Adverse Effect on the Company and
         its Subsidiaries, taken as a whole.

                  (ee) No  material  labor  dispute  with the  employees  of the
         Company or any of its  Subsidiaries  exists,  except as described in or
         contemplated  by the  Final  Memorandum,  or, to the  knowledge  of the
         Company,  is  imminent;  and the Company is not aware of any  existing,
         threatened or imminent labor disturbance by the employees of any of its
         principal suppliers, manufacturers or contractors that might reasonably
         be  expected to have a Material  Adverse  Effect on the Company and its
         Subsidiaries, taken as a whole.

                  (ff) (i) The Company and its  Subsidiaries are insured against
         such  losses and risks and in such  amounts as the  Company  reasonably
         believes are prudent and customary in the  businesses in which they are
         engaged;  (ii)  neither the Company  nor any such  Subsidiary  has been
         refused any insurance coverage sought or applied for; and (iii) neither
         the Company nor any such  Subsidiary  has any reason to believe that it
         will not be able to renew its existing  insurance  coverage as and when
         such  coverage  expires  or to obtain  similar  coverage  from  similar
         insurers as may be  necessary  to continue  its business at a cost that
         would  not  have a  Material  Adverse  Effect  on the  Company  and its
         Subsidiaries,  taken as a whole, except as described in or contemplated
         by the Final Memorandum.

                  (gg) The  Company  and its  Subsidiaries  maintain a system of
         internal accounting controls sufficient to provide reasonable assurance
         that (i)  transactions  are executed in  accordance  with  management's
         general or specific  authorizations;  (ii) transactions are recorded as
         necessary to permit  preparation of financial  statements in conformity
         with  generally  accepted  accounting  principles and to maintain asset
         accountability;  (iii) access to assets is permitted only in accordance
         with  management's  general  or  specific  authorization;  and (iv) the
         recorded accountability for assets is compared with the existing assets
         at reasonable intervals and appropriate action is taken with respect to
         any differences.

                  2. AGREEMENTS TO SELL AND PURCHASE. The Trust hereby agrees to
sell to the several Placement Agents, and each Placement Agent upon the basis of
the  representations  and  warranties  herein  contained,  but  subject  to  the
conditions  hereinafter stated,  agrees,  severally and not jointly, to purchase
the respective  number of Firm  Securities set forth in Schedule II opposite its
name from the Trust,  at a purchase  price of $50.00 per  Convertible  Preferred
Security (the "PURCHASE PRICE").

                  On the  basis of the  representations  and  warranties  of the
Trust and the Company contained in this Agreement,  and subject to its terms and
conditions,  the Trust  agrees to sell to the  Placement  Agents the  Additional
Securities,  and the Placement Agents shall have a right to purchase,  severally
and not jointly, up to 600,000 Additional Securities at the Purchase Price, plus
accrued  dividends,  if any. If the  Placements  Agents  elect to exercise  such
option,  the  Placements  Agents  shall so notify  the Trust and the  Company in
writing not later than 30 days after the date of this  Agreement,  which  notice
shall  specify  the  number of  Additional  Securities  to be  purchased  by the
Placement  Agents and the date on which  such  Additional  Securities  are to be
purchased.  Such date may be the same as the Closing  Date but not earlier  than
the Closing Date nor later than ten business days after the date of such notice.
If any Additional  Securities are to be purchased,  each Placement Agent agrees,
severally  and not  jointly,  to purchase  the number of  Additional  Securities
(subject to such  adjustments to eliminate  fractional  securities the Placement
Agents may  determine)  that bears the same  proportion  to the total  number of
Additional Securities to be purchased as the number of Firm Securities set forth
in  Schedule I hereto  opposite  the name of such  Placement  Agent bears to the
total number of Firm Securities.

                  In  view  of the  fact  that  proceeds  from  the  sale of the
Convertible   Preferred  Securities  will  be  invested  by  the  Trust  in  the
Convertible Debentures, the Company hereby agrees to pay the Placement Agents as
compensation (the "PLACEMENT  AGENTS'  COMPENSATION")  for the Placement Agents'
arranging for the  investment  therein of such proceeds,  $1.75 per  Convertible
Preferred Security purchased by the Placement Agents on the Closing Date and the
Option  Closing Date (as defined  below),  if any  ($5,250,000  in the aggregate
assuming  no exercise  of the  Placement  Agents'  option or  $6,300,000  in the
aggregate  assuming  exercise of such  option in full).  The  Placement  Agents'
Compensation  shall be  payable  to the  Placement  Agents by wire  transfer  of
immediately  available funds on the Closing Date and on the Option Closing Date,
if any.

                  The Trust and the Company hereby agree, jointly and severally,
that, without the prior written consent of Morgan Stanley & Co.  Incorporated on
behalf of the Placement Agents,  they will not, during the period ending 90 days
after the date of this Agreement,  (i) offer,  pledge,  sell,  contract to sell,
sell any option or  contract  to  purchase,  purchase  any option or contract to
sell, grant any option,  right or warrant to purchase,  or otherwise transfer or
dispose of, directly or indirectly,  any equity  securities of the Company,  the
Trust or any similar trust or any securities  convertible into or exercisable or
exchangeable  for any equity  security of the Company,  the Trust or any similar
trust  or (ii)  enter  into  any swap or other  agreement  or  arrangement  that
transfers to another,  in whole or in part,  directly or indirectly,  any of the
economic  consequences of ownership of any equity securities of the Company, the
Trust or any similar trust, whether any such transaction described in clause (i)
or (ii) above is to be settled by delivery of equity  securities of the Company,
the Trust or any similar  trust,  other  securities,  in cash or otherwise.  The
foregoing sentence shall not apply to (A) the Convertible  Preferred  Securities
to be sold  hereunder,  (B)  the  issuance  by the  Company  of the  Convertible
Debentures pursuant to the Debenture Purchase Agreement, (C) the issuance by the
Trust of the Trust Common Securities  pursuant to the Common Securities Purchase
Agreement,  (D) the  issuance  by the  Company  of shares of Common  Stock  upon
conversion  of the  Convertible  Preferred  Securities  sold  hereunder  and the
related  Convertible  Debentures,  (E) the  issuance by the Company of shares of
Common Stock or options to purchase  Common Stock  pursuant to employee  benefit
plans described in the Final  Memorandum or (F)  transactions by an person other
than the  Company  or the Trust  pertaining  to shares of Common  Stock or other
securities  acquired in open market  transactions  after the  completion  of the
offering of Convertible Preferred Securities.

                  3. TERMS OF OFFERING.  The  Placement  Agents have advised the
Trust and the  Company  that the  Placement  Agents will make an offering of the
Convertible  Preferred Securities purchased by the Placement Agents hereunder on
the terms set forth in the Final  Memorandum,  as soon as practicable after this
Agreement  is  entered  into  as in the  judgment  of the  Placement  Agents  is
advisable.

                  4. PAYMENT AND DELIVERY. Payment for the Firm Securities shall
be made in federal or other funds immediately available in New York City against
delivery  of such Firm  Securities  for the  respective  accounts of the several
Placement Agents at the closing to be held at

                                       11

are herein referred to as the "CLOSING DATE."

                  Payment for any Additional Securities shall be made in federal

Securities for the respective accounts of the Placement Agents at 9:00 A.M., New
York City time, on the date specified in the notice described in Section 2 or on
such other date, in any event not later than May 8, 2000, as shall be designated
in  writing  by the  Placement  Agents.  The time and date of such  payment  are
hereinafter referred to as the "OPTION CLOSING DATE."

                  Certificates for the Firm Securities and Additional Securities
shall be in  definitive  form or global  form,  as  specified  by the  Placement
Agents,  and registered in such names and in such denominations as the Placement
Agents shall  request in writing not later than two full  business days prior to
the  Closing  Date  or  the  Option  Closing  Date,  as the  case  may  be.  The
certificates  evidencing the Firm Securities and Additional  Securities shall be
delivered  to the  Placement  Agents on the Closing  Date or the Option  Closing
Date, as the case may be, with any transfer taxes payable in connection with the
transfer of the Convertible  Preferred  Securities to the Placement  Agents duly
paid, against payment of the Purchase Price therefor.

                  5.  CONDITIONS  TO  THE  PLACEMENT  AGENTS'  OBLIGATION.   The
obligations  of the  Placement  Agents to purchase  and pay for the  Convertible
Preferred Securities on the Closing Date is subject to the following conditions:

                  (a) Subsequent to the execution and delivery of this Agreement
         and prior to the Closing Date,

                           (i) there shall not have  occurred  any  downgrading,
                  nor  shall  any  notice  have been  given of any  intended  or
                  potential  downgrading or of any review for a possible  change
                  that does not indicate the  direction of the possible  change,
                  other than any notice  which shall  already have been given as
                  of the date hereof,  in the rating  accorded to the Company or
                  any of the Company's  securities or in the rating  outlook for
                  the Company by any "nationally  recognized  statistical rating
                  organization,"  as such term is defined  for  purposes of Rule
                  436(g)(2) under the Securities Act; and

                           (ii) there shall not have occurred any change, or any
                  development  involving a prospective change, in the condition,
                  financial  or  otherwise,  or in  the  earnings,  business  or
                  operations,  of the Company,  its  Subsidiaries  or the Trust,
                  taken as a whole,  from that set forth in the Final Memorandum
                  (exclusive of any amendments or supplements thereto subsequent
                  to the  date  of  this  Agreement)  that,  in  the  reasonable
                  judgment of the Placement Agents, is material and adverse

                                       12

<PAGE>



                  and that makes it, in the reasonable judgment of the Placement
                  Agents,  impracticable  to market  the  Convertible  Preferred
                  Securities on the terms and in the manner  contemplated in the
                  Final Memorandum.

                  (b) The  Placement  Agents shall have  received on the Closing
         Date a  certificate,  dated the Closing Date and signed by an executive
         officer of the  Company  and a Regular  Trustee  of the  Trust,  to the
         effect set forth in Section 5(a)(i) of this Agreement and to the effect
         that the  representations  and  warranties of the Company and the Trust
         contained in this Agreement are true and correct as of the Closing Date
         and that each of the Company and the Trust has complied with all of the
         agreements and satisfied all of the conditions  contained herein on its
         part to be performed  or  satisfied  hereunder on or before the Closing
         Date.  The  officer of the  Company  and  Regular  Trustee  signing and
         delivering  such  certificate  may  rely  upon  the  best of his or her
         knowledge as to any proceedings threatened.

                  (c) The Placement  Agents shall have received,  (A) on each of
         the date hereof and the Closing Date, a letter dated the date hereof or
         the  Closing   Date,  as  the  case  may  be,  in  form  and  substance
         satisfactory to the Placement Agents, from KPMG LLP, independent public
         accountants,   containing   statements  and  information  of  the  type
         ordinarily  included in accountants'  "comfort letters" to underwriters
         with  respect  to  the  financial   statements  and  certain  financial
         information  contained  in the  Final  Memorandum  and (B) on the  date
         hereof,   letters  dated  the  date  hereof,   in  form  and  substance
         satisfactory to the Placement Agents, from KPMG LLP, independent public
         accountants,  with respect to  agreed-upon  procedures to be applied to
         information  contained in the Final Memorandum with respect to billable
         minutes, revenue per billable minute and number of customers;  PROVIDED
         THAT the  letters  delivered  pursuant  to Section  5(c)(A) and Section
         5(c)(B)  shall use a "cut-off  date" not earlier  than 2 business  days
         prior to the date hereof.

                  (d) The  Placement  Agents shall have  received on the Closing
         Date an opinion of Kelley  Drye & Warren  LLP,  outside  counsel to the
         Company,  dated the Closing Date, to the effect set forth in EXHIBIT D.
         Such opinion shall be rendered to the  Placement  Agents at the request
         of the Company and the Trust and shall so state therein.

                  (e) The  Placement  Agents shall have  received on the Closing
         Date opinions of foreign local counsel in Germany, Switzerland,  Italy,
         France,  Belgium,  Spain, The Netherlands and the United Kingdom, dated
         the  Closing  Date,  each to the effect set forth in EXHIBIT E or as to
         such other form as agreed to by the  Placement  Agents.  Such  opinions
         shall be rendered to the Placement Agents at the request of the Company

         together  with an opinion of Nebraska  counsel,  each dated the Closing

         thereto and any  documents  incorporated  by reference  therein as such
         Placement Agent may reasonably request.

                  (b) Before amending or supplementing the Final Memorandum,  to
         furnish to each Placement Agent a copy of each such proposed  amendment
         or supplement and not to use any such proposed  amendment or supplement
         without the consent of Morgan Stanley & Co. Incorporated, which consent
         shall not be unreasonably withheld or delayed.

                  (c) If,  during such period after the date hereof and prior to
         the date on which all of the  Convertible  Preferred  Securities  shall
         have been  sold by the  Placement  Agents,  any  event  shall  occur or
         condition  exist as a  result  of  which  it is  necessary  to amend or
         supplement  the  Final  Memorandum  in  order  to make  the  statements
         therein, in the light of the circumstances when the Final Memorandum is
         delivered  to a  purchaser,  not  misleading,  or if, in the opinion of
         counsel to the Placement  Agents it is necessary to amend or supplement
         the Final  Memorandum  to comply  with  applicable  law,  forthwith  to
         prepare and  furnish,  at its own  expense,  to the  Placement  Agents,
         either  amendments or supplements  to the Final  Memorandum so that the
         statements in the Final  Memorandum as so amended or supplemented  will
         not, in the light of the  circumstances  when the Final  Memorandum  is
         delivered  to  a  purchaser,   be  misleading  or  so  that  the  Final
         Memorandum, as so amended or supplemented,  will comply with applicable
         law.

                  (d) To endeavor to qualify  the Offered  Securities  for offer
         and sale under the securities or Blue Sky laws of such jurisdictions as
         the  Placement  Agents shall  reasonably  request;  PROVIDED THAT in no
         event shall the Company be  obligated  to qualify to do business in any
         jurisdiction  in which it is not now so qualified or to take any action
         which would subject it to taxation in any  jurisdiction  in which it is
         not now so subject or to service or process in suits,  other than those
         arising out of the  offering or sale of the Offered  Securities  in any
         jurisdiction in which it is not now so subject.

                  (e) To  reserve  and  keep  available  at all  times,  free of
         preemptive  and similar  rights,  shares of Viatel Common Stock for the
         purpose of enabling  the Company to satisfy  any  obligations  to issue
         shares of Viatel Common Stock upon the  conversion  of the  Convertible
         Debentures and the Convertible Preferred Securities.

                  (f)  Whether  or not  the  transactions  contemplated  in this
         Agreement are  consummated or this  Agreement is terminated,  to pay or
         cause to be paid all reasonable expenses incident to the performance of
         its obligations under this Agreement, including: (i) the preparation of
         each  Memorandum and all amendments and supplements  thereto,  (ii) the
         preparation, issuance and delivery of the Offered Securities, (iii) the

         filing  fees and the  fees and  disbursements  of one  counsel  for the
         Placement  Agents in connection  therewith  and in connection  with the

         (vi) any fees charged by rating agencies, (vii) all reasonable document
         production  charges and expenses of one counsel to the Placement Agents
         (but not including their fees for professional  services) in connection
         with the preparation of this  Agreement,  (viii) the fees and expenses,
         if any,  incurred in  connection  with the  admission  of such  Offered
         Securities  for trading in the Private  Offerings,  Resales and Trading

         market system,  (ix) the costs and expenses of the Company  relating to
         investor presentations on any "road show" undertaken in connection with
         the marketing of the  offering,  whether by  traditional  or electronic

         production of road show slides and  graphics,  fees and expenses of any
         consultants engaged in connection with the road show presentations with
         the prior approval of the Company,  travel and lodging  expenses of the
         representatives  and officers of the Company and any such  consultants,
         and the cost of any aircraft chartered in connection with the road show
         with the  prior  approval  of the  Company,  (x) all fees and  expenses

         transfer  agents,  registrars  and  depositaries,  and (xii) such other
         reasonable  costs  and  expenses  incident  to the  performance  of the
         obligations  of  the  Company  hereunder  for  which  provision  is not
         otherwise made in this Section. It is understood,  however, that except
         as provided in this Section 6, Section 8 and Section 10, the  Placement
         Agents will pay all of their  costs and  expenses,  including  fees and
         disbursements of their counsel, transfer taxes payable on resale of any
         of the  Convertible  Preferred  Securities by them and any  advertising
         expenses connected with any offers they may make.

                  (g)  Neither  the  Company  nor the  Trust  nor  any of  their
         respective  Affiliates  will sell,  offer for sale or solicit offers to
         buy or  otherwise  negotiate  in respect of any security (as defined in
         the Securities  Act) which would be integrated  with the sale of any of
         the Offered Securities in a manner which would require the registration
         under the Securities Act of any of such Offered Securities.

                  (h) Neither the Company nor any  Subsidiary  will  solicit any
         offer to buy or offer or sell any of the Offered Securities by means of
         any form of general  solicitation  or general  advertising  (within the
         meaning  of Rule  502(c)  under the  Securities  Act) or in any  manner
         involving a public  offering  within the meaning of Section 4(2) of the
         Securities  Act,  except  as may be  contemplated  by the  Registration
         Rights Agreement.

                  (i) While any of the  Offered  Securities  remain  "restricted
         securities" within the meaning of Rule 144 under the Securities Act, to
         make  available,  upon  request,  to any seller of any of such  Offered
         Securities  the  information  concerning  the  Company  and  the  Trust
         specified  in Rule  144A(d)(4)  under the  Securities  Act,  unless the
         Company is then subject to and in  compliance  with Section 13 or 15(d)
         of the Exchange Act.

                                       16

<PAGE>



                  (j)  To  use  its  reasonable   best  efforts  to  permit  the
         Convertible Preferred Securities and, if the Convertible Debentures are
         at any time  distributed to holders,  the Convertible  Debentures to be
         designated   PORTAL   securities  in  accordance  with  the  rules  and
         regulations adopted by the National  Association of Securities Dealers,
         Inc. relating to trading in the PORTAL Market.

                  (k) The Company  shall not,  and shall use its best efforts to
         cause its  Affiliates  not to,  purchase  and then resell or  otherwise
         transfer any of the Offered Securities.

                  7. OFFERING OF CONVERTIBLE PREFERRED SECURITIES;  RESTRICTIONS
ON TRANSFER. (a) Each Placement Agent, severally and not jointly, represents and
warrants that such Placement Agent is a qualified institutional buyer as defined
in Rule 144A under the Securities Act (a "QIB"). Each Placement Agent, severally
and not  jointly,  agrees  with the  Company  and the Trust that (i) it will not
solicit offers for, or offer or sell,  Convertible  Preferred  Securities by any
form of general  solicitation or general advertising (as those terms are used in
Rule  502(c)  under the  Securities  Act) or in any  manner  involving  a public
offering  within the meaning of Section 4(2) of the  Securities  Act and (ii) it
will solicit offers for  Convertible  Preferred  Securities  only from, and will
offer such Convertible  Preferred Securities only to, persons that it reasonably
believes  to be  other  QIBs  who,  in  purchasing  such  Convertible  Preferred
Securities  are  deemed to have  represented  and agreed as  provided  in either
Memorandum under the caption "Transfer Restrictions."

                  (b)  Each   Placement   Agent,   severally  and  not  jointly,
represents,  warrants,  and agrees with respect to offers and sales  outside the
United States that:

                  (i) it understands that no action has been or will be taken in
         any jurisdiction by the Company or the Trust that would permit a public
         offering of the  Convertible  Preferred  Securities,  or  possession or
         distribution  of either  Memorandum or any other  offering or publicity
         material  relating  to the  Convertible  Preferred  Securities,  in any
         country or jurisdiction where action for that purpose is required;

                  (ii) such Placement Agent will comply with all applicable laws
         and  regulations  in each  jurisdiction  in which it acquires,  offers,
         sells  or  delivers  Convertible  Preferred  Securities  or  has in its
         possession or distributes either Memorandum or any such other material,
         in all cases at its own expense;

                  (iii) such  Placement  Agent has (A) not  offered or sold and,
         prior to the date six months after the Closing Date,  will not offer or
         sell any  Convertible  Preferred  Securities  to  persons in the United
         Kingdom  except to persons whose  ordinary  activities  involve them in
         acquiring,  holding, managing or disposing of investments (as principal
         or  agent)  for the  purposes  of  their  businesses  or  otherwise  in
         circumstances  which have not  resulted and will not result in an offer
         to the public in the United  Kingdom  within the  meaning of the Public
         Offers of  Securities  Regulations  1995;  (B) complied and will comply
         with all

                                       17

<PAGE>



         applicable  provisions of the Financial  Services Act 1986 with respect
         to  anything  done  by it in  relation  to  the  Convertible  Preferred
         Securities in, from or otherwise involving the United Kingdom;  and (C)
         only  issued or passed on and will only  issue or pass on in the United
         Kingdom any document received by it in connection with the issue of the
         Convertible Preferred Securities to a person who is of a kind described
         in  Article  11(3)  of the  Financial  Services  Act  1986  (Investment
         Advertisements)  (Exemptions)  Order 1996,  or is a person to whom such
         document may otherwise lawfully be issued or passed on; and

                  (iv) such Placement  Agent  understands  that the  Convertible
         Preferred Securities have not been and will not be registered under the
         Securities and Exchange Law of Japan,  and  represents  that it has not
         offered  or  sold,  and  agrees  that it will not  offer  or sell,  any
         Convertible Preferred Securities directly or indirectly in Japan or for
         the account of any resident  thereof  except  pursuant to any exemption
         from the  registration  requirements of the Securities and Exchange Law
         of Japan and  otherwise in  compliance  with  applicable  provisions of
         Japanese law.

                  8. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to
indemnify and hold harmless each Placement Agent,  and each person,  if any, who
controls  any  Placement  Agent  within the meaning of either  Section 15 of the
Securities  Act or Section 20 of the  Exchange  Act from and against any and all
losses,  claims,  damages and liabilities  (including,  without limitation,  any
legal or other  expenses  reasonably  incurred in connection  with  defending or
investigating  any such  action or  claim)  caused by any  untrue  statement  or
alleged  untrue  statement of a material fact  contained in each  Memorandum (as
amended or  supplemented  if the Company shall have  furnished any amendments or
supplements  thereto),  or caused by any  omission or alleged  omission to state
therein a material fact necessary to make the statements  therein,  in the light
of the  circumstances  under  which they were made,  not  misleading;  PROVIDED,
HOWEVER,  that the foregoing indemnity agreement with respect to any Preliminary
Memorandum  shall not inure to the benefit of any Placement  Agent from whom the
person  asserting  any such losses,  claims,  damages or  liabilities  purchased
Convertible  Preferred  Securities,  or any person  controlling  such  Placement
Agent, if a copy of the Final Memorandum (as then amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) was not sent
or given by or on behalf of such  Placement  Agent to such person at or prior to
the written confirmation of the sale of the Convertible  Preferred Securities to
such person,  and if the Final Memorandum (as so amended or supplemented)  would
have  cured  the  defect  giving  rise  to  such  losses,   claims,  damages  or
liabilities,  unless such failure is the result of  noncompliance by the Company
with Section 6(a) hereof;  PROVIDED FURTHER that each of the Company will not be
liable in any such case to the  extent,  but only to the  extent,  that any such
losses,  claims,  damages or liabilities are caused by any such untrue statement
or omission or alleged  untrue  statement  or  omission  based upon  information
relating  to any  Placement  Agent  furnished  to the Company in writing by such
Placement Agent expressly for use therein.


                                       18

<PAGE>



                  (b) Each Placement Agent agrees, severally and not jointly, to
indemnify and hold harmless the Company,  its  directors,  its officers and each
person, if any, who controls the Company within the meaning of either 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 such Placement Agent, but only with
reference  to  information  relating to such  Placement  Agent  furnished to the
Company  in  writing  by  such  Placement  Agent  expressly  for  use in  either
Memorandum or any amendments or supplements thereto.

                  (c)  In  case  any  proceeding   (including  any  governmental
investigation)  shall be  instituted  involving  any  person in respect of which
indemnity  may be sought  pursuant to any  provision  of Section 8(a) or Section
8(b),  such person (the  "INDEMNIFIED  PARTY") shall promptly  notify the person
against whom such indemnity may be sought (the "INDEMNIFYING  PARTY") in writing
(but the  failure to so notify an  indemnifying  party shall not relieve it from
any liability  which it may have under this Section 8, except to the extent that
it has been  prejudiced  in any material  respect by such  failure,  or from any
liability it may otherwise have) and the indemnifying party, upon request of the
indemnified  party,   shall  retain  counsel  reasonably   satisfactory  to  the
indemnified  party  to  represent  the  indemnified  party  and any  others  the
indemnifying  party may designate in such  proceeding and shall pay the fees and
disbursements  of  such  counsel  related  to  such  proceeding.   In  any  such
proceeding,  any  indemnified  party  shall  have the  right to  retain  its own
counsel,  but the fees and expenses of such  counsel  shall be at the expense of
such  indemnified  party unless (i) the  indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall  not,  in  respect  of the  legal  expenses  of any  indemnified  party in
connection with any proceeding or related  proceedings in the same jurisdiction,
be liable for the  reasonable  fees and expenses of more than one separate  firm
(in addition to any local counsel) for all such indemnified parties and that all
such fees and expenses shall be reimbursed as they are incurred. Such firm shall
be designated  in writing by Morgan  Stanley & Co.  Incorporated  in the case of
parties  indemnified  pursuant to Section 8(a) and by the Company in the case of
parties  indemnified  pursuant to Section 8(b). The indemnifying party 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 party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding  the foregoing  sentence,  if at any time an  indemnified  party
shall have requested an indemnifying  party to reimburse the  indemnified  party
for fees and  expenses  of  counsel  as  contemplated  by the  second  and third
sentences  of this  paragraph,  the  indemnifying  party 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  party of the aforesaid  request and (ii) such  indemnifying  party
shall not have reimbursed the indemnified  party in accordance with such request
prior to the date of such settlement.  No indemnifying party shall,  without the
prior written consent of the indemnified party, which consent may not be

                                       19

<PAGE>



unreasonably  withheld,  effect any  settlement  of any  pending  or  threatened
proceeding  in  respect of which any  indemnified  party is or could have been a
party  and  indemnity  could  have been  sought  hereunder  (whether  or not any
indemnified  party is an actual or potential  party to such  proceeding) by such
indemnified party, unless such settlement  includes an unconditional  release of
such indemnified  party from all liability on claims that are the subject matter
of such proceeding.

                  (d) To the  extent  the  indemnification  provided  for in any
provision of Section 8(a) or Section 8(b) is unavailable to an indemnified party
or  insufficient  in  respect of any  losses,  claims,  damages  or  liabilities
referred to therein, then each indemnifying party under such section, in lieu of
indemnifying such indemnified  party thereunder,  shall contribute to the amount
paid or payable by such  indemnified  party as a result of such losses,  claims,
damages or liabilities  (i) in such  proportion as is appropriate to reflect the
relative  benefits  received by the Company and the Trust,  on the one hand, and
Placement  Agents,  on the other hand,  from the  offering  of such  Convertible
Preferred Securities, or (ii) if the allocation provided by clause 8(d)(i) above
is not permitted by applicable  law, in such  proportion  as is  appropriate  to
reflect not only the relative  benefits  referred to in clause 8(d)(i) above but
also the relative fault of the Company and the Trust and the Placement Agents in
connection  with the  statements  or  omissions  that  resulted in such  losses,
claims,  damages  or  liabilities,  as  well  as any  other  relevant  equitable
considerations.  The relative benefits received by the Company and the Trust, on
the one hand, and the Placement  Agents,  on the other hand, in connection  with
the offering of the Convertible  Preferred  Securities  shall be deemed to be in
the same  respective  proportions  as the net proceeds  from the offering of the
Convertible  Preferred  Securities  (net of discounts and commissions but before
deducting  expenses)  received  by the  Company  and the  Trust  and  the  total
discounts and  commissions  received by the Placement  Agents in respect thereof
bear to the aggregate offering price of $50 per Convertible  Preferred Security.
The  relative  fault of the  Company  and the  Trust,  on the one hand,  and the
Placement  Agents, on the other hand, 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 and the Trust or the  Placement  Agents and
the parties' relative intent,  knowledge,  access to information and opportunity
to correct  or  prevent  such  statement  or  omission.  The  Placement  Agents'
respective  obligations to contribute  pursuant to this Section 8 are several in
proportion to the respective  number of Convertible  Preferred  Securities  they
have purchased hereunder and not joint.

                  (e) The Company, the Trust and the Placement Agents agree that
it would not be just or  equitable  if  contribution  pursuant to this Section 8
were determined by PRO RATA allocation or by any other method of allocation that
does not take  account of the  equitable  considerations  referred to in Section
8(d).  The amount  paid or payable  by an  indemnified  party as a result of the
losses,  claims, damages and liabilities referred to in Section 8(d) above shall
be deemed to include,  subject to the limitations set forth above,  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or  defending  any such  action  or  claim.  Notwithstanding  the
provisions of this Section 8, the Placement Agents

                                       20

<PAGE>



shall not be required to contribute  any amount in excess of the amount by which
the total price at which the Convertible  Preferred  Securities  resold by it in
the initial placement of such Convertible  Preferred  Securities were offered to
investors  exceeds  the amount of any  damages  that the  Placement  Agents have
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 remedies  provided for in this Section 8 are
not exclusive and shall not limit any rights or remedies  which may otherwise be
available to any indemnified party at law or in equity.

                  (f) The indemnity  and  contribution  provisions  contained in
this Section 8 and the  representations,  warranties and other statements of the
Company and the Trust contained in this Agreement shall remain  operative and in
full force and effect regardless of (i) any termination of this Agreement,  (ii)
any  investigation  made by or on behalf of any  Placement  Agent or any  person
controlling  any  Placement  Agent  or by or on  behalf  of the  Trust,  the VFT
Trustees,  the  Company,  or any of its  officers  or  directors  or any  person
controlling  the Company or the Trust,  and (iii)  acceptance of and payment for
any of the Convertible Preferred Securities.

                  9. TERMINATION. This Agreement shall be subject to termination
by  notice  given by the  Placement  Agents  to the  Company,  if (a)  after the
execution  and  delivery of this  Agreement  and prior to the  Closing  Date (i)
trading  generally shall have been suspended or materially  limited on or by, as
the  case  may be,  any of the New  York  Stock  Exchange,  the  American  Stock
Exchange,  the National  Association  of Securities  Dealers,  Inc., the Chicago
Board of Options Exchange,  the Chicago Mercantile Exchange or the Chicago Board
of  Trade,  (ii)  trading  of any  securities  of the  Company  shall  have been
suspended on any  exchange or in any  over-the-counter  market,  (iii) a general
moratorium on commercial banking activities in New York shall have been declared
by either  Federal  or New York  State  authorities  or (iv)  there  shall  have
occurred any outbreak or  escalation of  hostilities  or any change in financial
markets or any  calamity or crisis  that,  in your  judgment,  is  material  and
adverse and (b) in the case of any of the events  specified  in clauses  9(a)(i)
through  9(a)(iv)  above,  such event,  singly or  together  with any other such
event,  makes it, in your  judgment,  impracticable  to market  the  Convertible
Preferred  Securities on the terms and in the manner  contemplated  in the Final
Memorandum.

                  10. EFFECTIVENESS; DEFAULTING PLACEMENT AGENTS. This Agreement
shall become  effective  upon the execution  and delivery  hereof by the parties
hereto.

                  If, on the Closing  Date or the Option  Closing  Date,  as the
case may be,  any one or more of the  Placement  Agents  shall fail or refuse to
purchase  Convertible  Preferred  Securities  that it has or they have agreed to
purchase  hereunder  on such  date,  and the  aggregate  number  of  Convertible
Preferred  Securities which such defaulting  Placement Agent or Placement Agents
agreed  but  failed or refused to  purchase  is not more than  one-tenth  of the
aggregate number of the Convertible Preferred Securities to be purchased on such
date, the other Placement Agents shall be obligated severally in the proportions
that the number of Firm Securities set forth opposite

                                       21

<PAGE>



their  respective  names in  Schedule  I bears to the  aggregate  number of Firm
Securities  set forth  opposite the names of all such  non-defaulting  Placement
Agents,  or in such  other  proportions  as you may  specify,  to  purchase  the
Convertible  Preferred  Securities  which  such  defaulting  Placement  Agent or
Placement Agents agreed but failed or refused to purchase on such date; PROVIDED
that in no event shall the number of Convertible  Preferred  Securities that any
Placement  Agent has agreed to purchase  pursuant to this Agreement be increased
pursuant to this  Section 10 by an amount in excess of  one-ninth of such number
of  Convertible  Preferred  Securities  without  the  written  consent  of  such
Placement  Agent.  If, on the Closing  Date,  any  Placement  Agent or Placement
Agents shall fail or refuse to purchase Firm Securities and the aggregate number
of Firm  Securities  with  respect  to which  such  default  occurs is more than
one-tenth  of the  aggregate  number of Firm  Securities  to be  purchased,  and
arrangements  satisfactory to you, the Trust and the Company for the purchase of
such Firm  Securities  are not made  within 36 hours  after such  default,  this
Agreement shall terminate  without  liability on the part of any  non-defaulting
Placement  Agent,  the Trust or the Company.  In any such case either you or the
Trust shall have the right to postpone  the  Closing  Date,  but in no event for
longer than seven days, in order that the required changes, if any, in the Final
Memorandum or in any other documents or arrangements may be effected. If, on the
Option  Closing  Date,  any  Placement  Agent or Placement  Agents shall fail or
refuse to purchase Additional  Securities and the aggregate number of Additional
Securities  with respect to which such default  occurs is more than one-tenth of
the   aggregate   number  of  Additional   Securities   to  be  purchased,   the
non-defaulting  Placement  Agents shall have the option to (i)  terminate  their
obligation hereunder to purchase Additional Securities or (ii) purchase not less
than the number of  Additional  Securities  that such  non-defaulting  Placement
Agents would have been obligated to purchase in the absence of such default. Any
action taken under this  paragraph  shall not relieve any  defaulting  Placement
Agent from  liability  in respect of any default of such  Placement  Agent under
this Agreement.

                  If this Agreement shall be terminated by the Placement Agents,
or any of them,  because of any failure or refusal on the part of the Company or
the Trust to comply with the terms or to fulfill any of the  conditions  of this
Agreement,  or if for any  reason the  Company  or the Trust  shall be unable to
perform its obligations  under this Agreement  (other than by reason of a breach
of this  Agreement by any of the  Placement  Agents),  the Company and the Trust
will  reimburse  the  Placement  Agent  or  such  Placement  Agents  as  have so
terminated  this  Agreement  with  respect  to  themselves,  severally,  for all
out-of-pocket  expenses  (including the fees and  disbursements  of its counsel)
reasonably  incurred by such Placement  Agents in connection with this Agreement
or the offering contemplated hereunder.

                  11. NOTICES. All notices and other communications  required or
permitted  to be given  under this  Agreement  shall be in writing  and shall be

                    FORM OF KELLEY DRYE & WARREN LLP OPINION


                  In the course of the  preparation by the Trust and the Company
of the Final  Memorandum,  we have  participated  in conferences  with officers,
directors  and  representatives  of the Trust and the Company,  its  independent
auditors,  officers,  directors and your  representatives and representatives of
counsel for the Placement Agents at which  conferences the contents of the Final
Memorandum   and  related   matters  were   discussed.   Although  we  have  not
independently  verified the accuracy or completeness  of, or otherwise  verified
the statements made in the Final  Memorandum  (other than as expressly  provided
above),  nothing has come to our  attention  that has led us to believe that the
Final  Memorandum,  as of its  date or the  date  hereof,  contained  an  untrue
statement of a material  fact or omitted to state a material  fact  necessary in
order the make the statements  therein,  in the light of the circumstances under
which they were made, not misleading.  Notwithstanding the foregoing, we are not
expressing any belief as to the financial  statements  and supporting  notes and
schedules and other financial data contained in the Final Memorandum.

                                                                       EXHIBIT E

                      FORM OF FOREIGN LOCAL COUNSEL OPINION


                  (A) [________] (the "Company") has been duly incorporated,  is
validly  existing  as a  company  under the laws of [Name of  Country],  has the
corporate power and authority to own its property and to conduct its business as
described in the Offering Memorandum of Viatel Financing Trust I dated April __,
2000 (the "Final Memorandum") and is duly qualified to transact business in each
jurisdiction in which the conduct of its business or its ownership or leasing of
property requires such  qualification  (except to the extent that the failure to
be so  qualified  would not in our view have a  Material  Adverse  Effect on the
Company and its subsidiaries taken as a whole).

                  (B) The Company has no subsidiaries.

                  (C) The Company  has all  materially  necessary  certificates,
orders, permits, licenses,  authorizations,  consents and approvals of and from,
and has  made all  declarations  and  filings  with  all  relevant  governmental
authorities,  all  self-regulatory  organizations  and all  relevant  courts and
tribunals,  to own,  lease,  license  and use its  properties  and assets and to
conduct its business in the manner  described in the Final  Memorandum,  and, to
the best of our  knowledge,  after due  inquiry has not  received  any notice of
proceedings  relating to revocation or  modification  of any such  certificates,
orders, permits,  licenses,  authorizations,  consents or approvals,  nor is the
Company in  violation  of, or in  default  under,  any  federal,  state,  local,
national or regional law, regulation, rule, decree, order or judgment applicable
to the Company,  the effect of which,  singly or in the aggregate,  would have a
material adverse effect on the prospects,  condition, financial or otherwise, or
in the  earnings,  business or  operations  of the Company,  except as described
herein or in the Final Memorandum.

                  (D) The statements in the Final  Memorandum  under the caption
"Business  --  [_______]"  are  accurate  in all  material  respects  and fairly
summarize all matters referred to therein.

                  (E)  There  are  no   restrictions   (legal,   contractual  or
otherwise) on the ability of the Company to declare and pay any dividend or make
any payment or transfer  of  property or assets to its  stockholders  other than
those described in the Final Memorandum and such  restrictions as would not have
a material adverse effect on the prospects,  condition,  financial or otherwise,
or in the earnings, business or operations of the Company and such descriptions,
if any, fairly summarize such restrictions.

                     FORM OF U.S. REGULATORY COUNSEL OPINION


         Pursuant  to  Section  5(f)  of the  Placement  Agreement,  Morrison  &
Foerster LLP,  regulatory  counsel for the Company,  shall furnish an opinion to
the effect that:

                  (A) (1) the execution and delivery of the Placement  Agreement
         by the Trust and the Company and the  consummation of the  transactions
         contemplated thereby do not violate (i) the federal  Communications Act
         of 1934, as amended, and the  Telecommunications Act of 1996, any rules
         or  regulations  of  the  Federal  Communications   Commission  ("FCC")
         applicable to the Company  (collectively,  the  "Communications  Act"),
         (ii) any state  telecommunications  law, rules or  regulations  ("State
         Law")  applicable  to the  Company,  and  (iii)  to the  best  of  such
         counsel's  knowledge,  any decree  from any court,  and (2) no consent,
         approval, authorization or order of or filing with the FCC or any state
         authority overseeing telecommunications matters ("State Authority"), is
         necessary for the execution and delivery of the Placement  Agreement by
         the  Company and the Trust and except to the extent that the failure to
         obtain such consents,  approvals,  authorizations  or orders or to make
         filings with, the FCC or any State Authority would not, individually or

         Re:  VIATEL FINANCING TRUST I

Ladies and Gentlemen:

         The undersigned, an officer and/or director of Viatel, Inc., a Delaware
corporation (the "Company"),  understands that Morgan Stanley & Co. Incorporated
("Morgan  Stanley") intends to enter into a Placement  Agreement (the "Placement
Agreement") with the Company and Viatel Financing Trust I, a statutory  business
trust formed under the laws of the State of Delaware  (the  "Trust"),  providing
for the offering by the several Placement Agents,  including Morgan Stanley (the
"Placement  Agents")  of  convertible   preferred   securities  (the  "Preferred
Securities") of the Trust.

         To induce the Placement  Agents to enter into the Placement  Agreement,
and in recognition of the benefit that the offering of the Preferred  Securities
will confer upon the  undersigned as an officer and/or  director of the Company,
and for other good and valuable  consideration,  the receipt and  sufficiency of
which are hereby  acknowledged,  the undersigned hereby agrees that, without the
prior written consent of Morgan Stanley on behalf of the Placement  Agents,  the
undersigned will not, during the period commencing on the date hereof and ending
90 days after the date of the  Placement  Agreement,  (i) offer,  pledge,  sell,
contract to sell,  sell any option or contract to purchase,  purchase any option
or  contract  to sell,  grant any  option,  right or  warrant  to  purchase,  or
otherwise transfer or dispose of, directly or indirectly,  any equity securities
of the Company,  the Trust or any similar  trust or any  securities  convertible
into or exchangeable  or exercisable  for any equity  securities of the Company,
the Trust or any similar trust,  whether now owned or hereafter  acquired by the
undersigned or with respect to which the undersigned  has or hereafter  acquires
the power of disposition,  or (ii) enter into any swap or any other agreement or
arrangement  that  transfers  to  another,  in  whole or in  part,  directly  or
indirectly,  any  of the  economic  consequences  of  ownership  of  any  equity
securities  of the  Company,  the Trust or any similar  trust,  whether any such
transaction described in clause (i) or


<PAGE>


                                       I-2

(ii) above is to be settled by delivery of any equity securities of the Company,
the Trust or any similar  trust,  other  securities,  in cash or otherwise.  The
foregoing  sentence shall not apply to (a) the sale of any equity  securities to
the Placement  Agents pursuant to the Placement  Agreement,  or (b) transactions
relating to equity  securities  acquired in open market  transactions  after the
completion of the offering of the Preferred Securities.

         The  undersigned  recognizes  that  whether or not the  offering of the
Preferred  Securities actually occurs depends on a number of factors,  including
market  conditions.  Any such offering will only be made pursuant to a Placement
Agreement,  the terms of which are subject to  negotiation  between the Company,
the Trust and the Placement Agents.

         In the event the Closing Date (as defined in the  Placement  Agreement)
does not occur by April 17, 2000,  this  lock-up  agreement  will  automatically
expire and be of no further effect.

         This  agreement  shall be governed by and construed in accordance  with
the laws of the State of New York.


                                                    Very truly yours,


                                                    Signature:

                  This PREFERRED  SECURITIES GUARANTEE AGREEMENT (the "Preferred
Securities Guarantee"), dated as of April 12, 2000, is executed and delivered by
Viatel,  Inc., a Delaware  corporation  (the  "Guarantor"),  and The Bank of New
York, a New York State banking corporation, as trustee (the "Preferred Guarantee
Trustee"),  for the benefit of the Holders (as defined herein) from time to time
of the Preferred  Securities (as defined herein) of Viatel  Financing Trust I, a
Delaware statutory business trust (the "Trust").

                  WHEREAS,  pursuant to an Amended and Restated  Declaration  of

liquidation  amount of $150,000,000  (plus up to an additional 600,000 preferred
securities,  having an aggregate  liquidation  amount of  $30,000,000,  to cover
over-allotments),  designated the 7 3/4% Trust Convertible  Preferred Securities
(the "Preferred Securities").

                  WHEREAS,   as  incentive  for  the  Holders  to  purchase  the
Preferred  Securities,  the Guarantor desires irrevocably and unconditionally to
agree,  to the  extent  set forth in this  preferred  Securities  Guarantee,  to
guarantee  the  obligations  of the  Trust  to  the  Holders  of  the  Preferred
Securities on the terms and conditions set forth herein.

                  WHEREAS,  the  Guarantor is also  executing  and  delivering a
guarantee  agreement  (the  "Common  Securities   Guarantee")  in  substantially
identical  terms to this Preferred  Securities  Guarantee for the benefit of the
holders of the Common Securities (as defined herein), except that if an event of
default (as defined in the Indenture (as defined  herein)),  has occurred and is
continuing,  the rights of holders of the Common Securities to receive Guarantee
Payments  (as  defined  in the  Common  Securities  Guarantee)  under the Common
Securities Guarantee shall be subordinated to the rights of Holders of Preferred
Securities  to  receive  Guarantee  Payments  (as  defined  herein)  under  this
Preferred Securities Guarantee.

                  NOW THEREFORE, in consideration of the purchase by each Holder
of Preferred  Securities,  which  purchase  the  Guarantor  hereby  agrees shall
benefit the  Guarantor,  the  Guarantor  executes  and delivers  this  Preferred
Securities Guarantee for the benefit of the Holders.

misconduct, except that:

                  (i) prior to the  occurrence of any Event of Default and after

                  Preferred Guarantee Trustee shall not be liable except for the
                  performance of such duties and obligations as are specifically
                  set  forth  in this  Preferred  Securities  Guarantee,  and no

                           (B) in the  absence  of bad  faith on the part of the
                  Preferred  Guarantee Trustee,  the Preferred Guarantee Trustee

         Preferred Securities Guarantee; and

         or otherwise incur personal  financial  liability it the performance of
         any of its duties or in the exercise of any of its rights or powers, if
         the  Preferred  Guarantee  Trustee  shall have  reasonable  grounds for
         believing  that  the  repayment  of  such  funds  or  liability  is not
         reasonably assured to it under

SECTION 5.1       Guarantee

                  The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders  the  Guarantee  Payments  (without  duplication  of amounts
theretofore  paid by the Trust),  as and when due,  regardless  of any  defense,

causing the Trust to pay such amounts to the Holders.

SECTION 5.2       Subordination

                  If an Event of  Default  (as  defined in the  Indenture),  has
occurred  and is  continuing,  the  rights of Holders  of Common  Securities  to
receive Guarantee Payments under the Common Securities Guarantee are subordinate
to the rights of Preferred  Securities to receive Guarantee  Payments under this
Preferred Securities Guarantee.

SECTION 5.3       Waiver of Notice and Demand

                  The  Guarantor  hereby  waives  notice of  acceptance  of this

apply, presentment,  demand for payment, any right to require a proceeding first
against the Trust or any other Person before  proceeding  against the Guarantor,
protest, notice of nonpayment,  notice of dishonor, notice of redemption and all
other notices and demands.

following:

                  (a) the release or waiver,  by operation of law or  otherwise,

         Securities to be performed or observed by the Trust;

                  (b) the  extension of time for the payment by the Trust of all
         or any  portion of the  Distributions,  Redemption  Price,  Liquidation
         Distribution or any other sums payable under the terms of the Preferred
         Securities  or the extension of time for the  performance  of any other
         obligation under,  arising out of, or in connection with, the Preferred
         Securities   (other   than  an   extension   of  time  for  payment  of
         Distributions,  Redemption Price, Liquidation Distribution or other sum
         payable that results from the extension of any interest  payment period
         on  the  Debentures  or  any  extension  of the  maturity  date  of the
         Debentures permitted by the Indenture);

                  (c) any failure,  omission,  delay or lack of diligence on the
         part  of  the  Holders  to  enforce,  assert  or  exercise  any  right,
         privilege,  power or remedy  conferred  on the Holders  pursuant to the
         terms of the  Preferred  Securities,  or any  action on the part of the
         Trust granting indulgence or extension of any kind;


                                       13

<PAGE>



                  (d) the  voluntary or  involuntary  liquidation,  dissolution,
         sale  of  any   collateral,   receivership,   insolvency,   bankruptcy,
         assignment for the benefit of creditors,  reorganization,  arrangement,
         composition or  readjustment  of debt of, or other similar  proceedings
         affecting, the Trust or any of the assets of the Trust;

                  (e) any  invalidity of, or defect or deficiency in, the
         Preferred Securities;

                  (f) the settlement or compromise of any obligation guaranteed
         hereby or hereby incurred; or

                  (g) any other  circumstance  whatsoever  that might  otherwise
         constitute a legal or equitable discharge or defense of a guarantor, it
         being  the  intent  of this  Section  5.4 that the  obligations  of the
         Guarantor  hereunder shall be absolute and unconditional  under any and
         all circumstances.

                  There shall be no obligation of the Holders to give notice to,
or obtain  consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.5       Rights of Holders

                  (a) The  Holders of a Majority  in  liquidation  amount of the
Preferred  Securities  have the right to direct  the time,  method  and place of
conducting of any proceeding for any remedy available to the Preferred Guarantee
Trustee in respect of this  Preferred  Securities  Guarantee or  exercising  any
trust or power  conferred  upon  the  Preferred  Guarantee  Trustee  under  this
Preferred Securities Guarantee.

                  (b) Any Holder of Preferred  Securities may directly institute
a legal  proceeding  against the  Guarantor  to enforce the  obligations  of the
Guarantor under this Preferred  Securities Guarantee without first instituting a
legal proceeding against the Trust, the Preferred Guarantee Trustee or any other
Person to the fullest extent permitted by law.

                  (c) If an Event of Default with respect to the  Debentures (an
"Indenture  Event of  Default"),  constituting  the  failure to pay  interest or
principal on the  Debentures on the date such interest or principal is otherwise
payable has occurred and is  continuing,  then a Holder of Preferred  Securities
may directly,  at any time, institute a proceeding for enforcement of payment to
such Holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate  liquidation amount of the Preferred Securities of
such Holder on or after the respective due date specified in the Debentures. The
Holders of Preferred  Securities will not be able to exercise directly any other
remedy  available  to the  holders of the  Debentures  unless the  Institutional
Trustee (as defined in the Indenture) fails to do so.

SECTION 5.7       Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the Holders
of Preferred Securities against the Trust in respect of any amounts paid to such
Holders by the Guarantor under this Preferred  Securities  Guarantee;  PROVIDED,
HOWEVER,  that the  Guarantor  shall  not  (except  to the  extent  required  by
mandatory  provisions  of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any  indemnity,  reimbursement  or other
agreement,  in all cases as a result of payment under this Preferred  Securities
Guarantee,  if, at the time of any such payment,  any amounts are due and unpaid
under this Preferred  Securities  Guarantee.  If any amount shall be paid to the
Guarantor in violation of the preceding  sentence,  the Guarantor agrees to hold
such amount in trust for the Holders and to pay over such amount to the Holders.

SECTION 5.8       Independent Obligations

                  The Guarantor  acknowledges that its obligations hereunder are
independent  of the  obligations  of the Trust  with  respect  to the  Preferred

hereunder to make  Guarantee  Payments  pursuant to the terms of this  Preferred
Securities Guarantee  notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.4 hereof.

thereof,  shall be  continuing,  (ii)  there  shall have  occurred  any Event of
Default or (iii) there shall have  occurred  and be  continuing  any event that,

and stock purchase plans).

SECTION 6.2       Ranking

                  (a) This Preferred  Securities  Guarantee  will  constitute an
unsecured  obligation of the Guarantor and will rank (i)  subordinate and junior
in right of  payment  to all  other  liabilities  of the  Guarantor  except  any
liabilities  that may be PARI PASSU  expressly by their  terms,  (ii) PARI PASSU

Guarantor's  common stock or rights under any of the  Guarantor's  benefit plans
for the Guarantor's  directors,  officers or employees;  or (vii) obligations of
the Guarantor under any dividend reinvestment and stock purchase plans).


SECTION 3.2.               RANKING

                  (a)  This  Common  Securities  Guarantee  will  constitute  an
         unsecured obligation of the Guarantor and will rank (i) subordinate and
         junior in right of payment to all other  liabilities  of the Guarantor,

         stock now or hereafter  issued by the  Guarantor and with any guarantee
         now or  hereafter  entered  into by the  Guarantor  in  respect  of any
         preferred or preference  stock of any Affiliate of the  Guarantor,  and
         (iii) senior to the Common Stock.

                  (b) The holders of any  obligations  of the Guarantor that are

         Guarantee  will be entitled to all of the rights inuring to the holders
         of "Senior  Indebtedness"  under Article 12 of the  Indenture,  and the

             WHEREAS,  the  Parties  now desire to amend and  restate  the Fixed

          SECTION 2. INTENT OF CONTRACT AND RELATIONSHIP OF THE PARTIES

2.1.  GENERALLY. The Contractor shall:

      (a)   undertake  all  necessary  Work and perform in full its  obligations
            hereunder  in order to plan,  supply,  install,  assemble,  test and
            furnish  to each Owner (to the  extent of its  respective  ownership
            interest  therein)  each Outside  Plant (or segment  thereof) as set
            forth in the Technical Requirements; and

      (b)   achieve RFS Acceptance  for each Outside Plant (or segment  thereof)
            on or before the Guaranteed RFS Date therefor,

      in each case, upon and subject to the provisions of this Contract.

2.2.  INTERPRETATION.  The Contractor shall perform all of the Work specified or
      reasonably  inferred  from this  Contract.  The  Contractor's  performance
      hereunder shall include everything requisite and necessary to complete the
      entire Work  notwithstanding the fact that every item necessarily involved
      may not be  specifically  mentioned  in the  Technical  Requirements.  The
      intent of this  Contract is to relieve the Owner  Persons of the necessity
      of engaging or  supplying  any labor,  service,  equipment  or material to
      complete  the Outside  Plants,  unless the labor,  service,  equipment  or
      material is expressly  itemized in this Contract as being furnished by any
      such Owner Persons.

2.3.  RELATIONSHIPS AMONG THE PARTIES. The Parties hereto agree that:

      (a)   THE OWNERS.  Each of the Owners is entering  into this Contract as a
            several but not joint obligor,  and, in any event, each such Owner's
            liability with respect to all obligations hereunder shall be limited
            pro rata to its  percentage of ownership in the Outside Plants to be
            delivered by the Contractor hereunder, which percentage shall be:

            (i)   [REDACTED], in the case of Viatel;

            (ii)  [REDACTED], in the case of MFN; and


                                       3
<PAGE>

        (iii) [REDACTED], in the case of Carrier 1,

            subject to the proviso that,  such  percentages may be adjusted from
            time to time and the Developer  shall  provide  timely Notice to the
            Contractor with respect to any such adjustment.

      (b)   APPOINTMENT  OF DEVELOPER  AS AGENT.  Each Owner has  appointed  the
            Developer as its sole and  exclusive  agent,  with full and complete
            authority to act on its behalf with respect to all matters  relating
            to the administration and performance of this Contract.

      (c)   NON-LIABILITY  OF THE DEVELOPER TO THE CONTRACTOR.  The Developer is
            acting  solely in the  capacity  as an agent of each Owner and shall
            bear no liability hereunder to any Contractor Person.

      (d)   EXCLUSIVE POINT OF CONTACT. No Owner Person other than the Developer
            shall be entitled to instruct or direct the Contractor  with respect
            to  any  matter  hereunder.   The  Contractor  shall  disregard  any
            instructions  purported  to be given on behalf  of any Owner  unless
            given by the Developer acting through its Developer's Representative
            appointed pursuant to Section 19.2. In the event,  however, that the
            Contractor  has  failed to achieve  RFS  Acceptance  of the  Outside
            Plants by March 31, 2000,  each Owner  (acting  singly or with other
            Owners as they may elect) shall be entitled to pursue all  available
            remedies  against the  Contractor to the full extent of such Owner's
            (or Owners') pro rata ownership interest in the Outside Plants.

      (e)   NO IMPLIED RELATIONSHIPS.  Unless expressly contemplated herein, the
            relationships  between  and among the  Parties  shall not be that of
            partners or joint  venturers,  and nothing herein contained shall be
            deemed to  constitute a  partnership  or joint  venture  among them.
            Except for the  Developer's  agency for the Owners as  expressed  in
            clause (b) of this Section 2.3 and  elsewhere in this  Contract,  or
            unless otherwise  expressly  stipulated  herein, no Party shall have
            authority  or power  to bind or act  unilaterally  as agent  for any
            other Party.

                          SECTION 3. CONTRACT DOCUMENTS

3.1.  FORM PART OF THIS CONTRACT. Each Contract Document shall be deemed to form
      and be read and  construed as part of this  Contract,  and all matters and
      things  herein  expressed as a duty or  obligation of either Party (either
      actual or potential) therein shall be the duty or obligation of such Party
      hereunder.

3.2.  CONFLICTS.  In the  event of any  conflict  between  a  provision  of this
      Contract  and a  provision  of any  Contract  Document,  the former  shall
      prevail.  In the event of any conflict  between or among the provisions of
      one or more Contract Documents that cannot be resolved by any provision of
      this  Contract,  then the  provision in the Contract  Document  having the
      highest order of precedence below shall prevail:

            Schedule  Recovery Plan immediately  after directed by the Developer
            to  implement  such  Schedule  Recovery  Plan  and  its  failure  to
            implement  it at the  rate of  progress  set  forth  therein,  shall
            constitute an Event of Default under Section 24.1(a) hereof.

      (b)   NO DIMINISHMENT.  The Contractor's preparation and implementation of
            any  Schedule  Recovery  Plan  shall in no way  relieve or limit the
            Contractor's  obligations to comply with the Critical Path Items set
            forth in the  Milestone  Schedule and to achieve RFS  Acceptance  by
            each  Guaranteed  RFS Date, and the  Developer's  acceptance of Work
            performed  pursuant to any such Schedule  Recovery Plan shall not be

      the Milestone Schedule, and providing projections (identifying anticipated
      items of Subcontractor  Supplies and Subcontractor  Services together with
      the  Subcontractor  Costs payable in respect  thereof) of the Reimbursable
      Costs  that  the  Contractor   reasonably  expects  to  incur  during  the
      subsequent month with a comparison of such  Reimbursable  Costs as against
      the budget; and, in connection therewith,  the Contractor shall (i) attend
      meetings with the Developer's Representative,  at such times and places as
      may be  reasonably  required  by the  Developer,  to discuss  the  general
      progress of the Work, and (ii) furnish,  at least twice  monthly,  summary
      progress reports as against the budget and the Milestone  Schedule and any

7.1.  GENERALLY.  APPENDIX 2 hereto sets forth the planned  Scheduled Route upon
      which  each  Outside  Plant is to be  completed.  It is the intent of this
      Contract  that  such  Scheduled   Route  shall,   to  the  maximum  extent
      practicable,  be located in its entirety  upon Public  Wayleaves  that the
      Contractor,  as agent for the  Owners,  shall  procure  and present to the
      Developer  for  approval  and  signature  in  accordance  with Section 7.2
      hereof.

7.2.  WAYLEAVE PROCUREMENT AND APPROVAL. As part of the Work, the Contractor has
      conducted,  and shall continue to conduct,  negotiations with Governmental
      Authorities  and  others in  appropriate  jurisdictions  to  document  and
      secure, as agent for the Owners,  sufficient Public Wayleaves to allow the
      Outside Plants to be completed  along the entirety of the Scheduled  Route
      in accordance  with the Technical  Requirements  and applicable  Codes and
      Standards.

      (a)   DOCUMENTATION  PROCEDURES. As part of the Work, the Contractor shall
            compile and prepare all documentation  necessary to secure each such
            Public  Wayleave  for the benefit of the Owners,  and shall  present
            such documentation to the Developer, whereupon the Developer shall:

            (i)   in the case of Public  Forms,  approve  and sign  (or,  in the
                  Developer's  discretion,  cause each  relevant  Owner to grant
                  power of attorney to a Contractor  Person to approve and sign)
                  each such Public Form, returning the same to the Contractor or
                  the appropriate Governmental Authority, as applicable,  within
                  a period of  [REDACTED]  Business  Days after the  Developer's
                  receipt thereof; and

            (ii)  in the case of Public Contracts meeting all criteria specified
                  in APPENDIX 5 hereto,  review,  approve,  sign and return each
                  such Public  Contract  to the  Contractor  or the  appropriate
                  Governmental  Authority,  as  applicable,  within a period  of
                  [REDACTED]   Business  Days  after  the  Developer's   receipt
                  thereof.

      (b)   GENERAL TERMS AND CONDITIONS OF PUBLIC  WAYLEAVES.  Without limiting
            the criteria  specified with respect to Public Contracts in APPENDIX


                                       10
<PAGE>

            5 hereto, each Public Wayleave procured by the Contractor,  as agent
            for the Owners,  shall,  absent a Regulatory  Change occurring after
            the RFS Date:

            (i)   be effective for the period  provided by the relevant Laws and
                  Codes and Standards relating thereto; and

            (ii)  [REDACTED]

      (c)   APPROVAL BY THE DEVELOPER. The Owners shall assume (in proportion to
            their pro rata  ownership  interests in the Outside  Plants) any and
            all costs or fees payable to any  Governmental  Authority in respect
            of the use and maintenance of Public  Wayleaves  entered into by the
            Developer,  and the  Contractor  shall be relieved  from any further
            liability with respect thereto.

7.3.  ALTERNATIVE  WAYLEAVES.  If the Contractor is unable, despite commercially
      reasonable  professional  efforts and compliance  with all applicable Laws
      and Codes and Standards,  to procure Public  Wayleaves with respect to any
      portion or portions of the Scheduled  Route it shall provide Notice to the
      Developer and, after consultation with the Developer, as part of the Work,
      prepare a  work-around  plan  identifying  alternative  wayleaves or other
      System access rights ("ALTERNATIVE WAYLEAVES") complying with this Section
      7.3  and  the  other  requirements  of  this  Contract  and  the  Contract
      Documents.

      (a)   GENERAL  REQUIREMENTS  FOR CONTRACTOR  PROPOSALS.  Each  Alternative
            Wayleave  proposed by the  Contractor  shall (x) be effective (or be
            subject  to  successive  renewal)  for  a  period  of no  less  than
            [REDACTED] from the RFS Date for the Outside Plant of which it
            is a part,  and (y) comply in all  respects  with the  criteria  set
            forth therefor in APPENDIX 5 hereto.  Each work-around plan prepared
            and submitted by the Contractor in connection  with any  Alternative
            Wayleave shall:

            (i)   contain a detailed  description of the terms and conditions of
                  each   Alternative   Wayleave,   demonstrating,   by  specific
                  reference  to the  appropriate  sections of APPENDIX 5 hereto,
                  satisfaction of each of the criteria set forth therein;


                                       11
<PAGE>

            (ii)  attach  form  documentation  for the  conveyance  of each such
                  Alternative Wayleave; and

            (iii) specify the adjustment to the Milestone  Schedule,  if any, to
                  which  the  Contractor  would be  entitled  if  Outside  Plant
                  completion   were  to  be   effected  on  the  basis  of  such
                  Alternative Wayleaves.

      (b)   DEVELOPER REVIEW AND APPROVAL. The Developer shall, immediately upon
            receipt thereof, review and consider each such work-around plan and,
            within [REDACTED] after such receipt, shall notify the Contractor:

            (i)   of its acceptance of such plan,  whereupon the Developer shall
                  (x) execute  and return to the  Contractor  the  documentation
                  presented  to  the  Developer   for  the   conveyance  of  the
                  applicable Alternative Wayleaves and, (y) if applicable, enter
                  into a Contract  Variation with the Contractor  reflecting the
                  appropriate adjustment to the Guaranteed RFS Dates; or

            (ii)  of its rejection thereof, specifying, by detailed reference to
                  each relevant Contract Document,  the Developer's  reasons for
                  its determination that (x) the Alternative  Wayleaves proposed
                  do not  comply  with the  criteria  set  forth in  APPENDIX  5
                  hereto,  or (y) such work-around plan is not acceptable to the
                  Developer  in  light  of  the  Vendor  Specifications,   other
                  Technical Requirements or applicable Codes and Standards;

            PROVIDED,  that  nothing in this  Section 7.3 shall be deemed to (A)
            require the  Developer  to consider or accept as part of the Work or
            pay for any  Contractor  proposal  that  does  not  comply  with the
            express  terms of this  Section 7 or any Contract  Document,  or (B)
            prohibit   or  limit  any   activity   by  the   Developer   in  the
            identification,   development   and   implementation   of   suitable
            work-around  plans,  subject to any rights that the  Contractor  may
            have for Contract Variations in respect of Work affected by any such
            plans.

                          SECTION 8. OWNER OBLIGATIONS

8.1.  OWNER-PROCURED  EQUIPMENT  AND VENDOR  SPECIFICATIONS.  Each  Owner  shall
      procure  and  install (or cause to be  installed)  each item of  equipment
      identified in APPENDIX 3 hereto (such items  individually or collectively,
      the "OWNER-PROCURED EQUIPMENT"), in each case, by the date(s) set forth in
      the Milestone  Schedule for the  Contractor's  commencement  of Work on or
      involving any such item. All vendors of Owner-Procured  Equipment shall be
      obligated by the Developer  or, as  applicable,  the relevant  Owner(s) to
      cooperate with the Contractor and to so conduct their operations so as not
      to interfere with or impede the Contractor in carrying out the Work,  and,
      to the  extent  of any  Owner-Caused  Delay  on  account  of any  Vendor's
      non-cooperation,  the Contractor shall be entitled to a Contract Variation
      in respect thereof  pursuant to Section 15.1 hereof.  Contractor shall use
      reasonable  efforts to avoid waste of Owner-Procured  Equipment.  Prior to


                                       12
<PAGE>

      the  Contractor's  commencement  of any Work (i) on or with respect to any
      item(s)  of  Owner-Procured  Equipment  or (ii)  that is,  by its  nature,
      dependent upon or subject to coordination with the  specifications for any
      item(s) of  Owner-Procured  Equipment,  the Developer shall furnish to the
      Contractor any  modifications or supplements to the Vendor  Specifications
      (all of which shall be  integrated  into and form a part of the  Technical
      Requirements)  for each  relevant item of  Owner-Procured  Equipment on or
      before the date set forth in the Milestone  Schedule for the  Contractor's
      commencement  of any such Work. If any  modification  or supplement to any
      Vendor  Specification  requires a change in the scope of Work as set forth
      in the Technical  Requirements  which affects  materially a Guaranteed RFS
      Date, the Parties shall  equitably  adjust the  applicable  Guaranteed RFS
      Date pursuant to a Contract Variation.

8.2.  POP SITES AND OWNER SPECIFICATIONS.  The Developer shall, as agent for and
      at the sole cost and expense of the  Owners,  select and procure POP Sites
      complying  in all  respects  with the POP Site  Specifications  annexed as
      APPENDIX 2 hereto.

      (a)   POP SITES GENERALLY.  With respect to each such POP Site so selected
            and  procured  after  the  effective  date  of  this  Contract,  the
            Developer shall:

            (i)   promptly  notify the Contractor of the location  thereof,  and
                  furnish  all   specifications   and  data  necessary  for  the
                  Contractor  to  verify  its  compliance   with  the  POP  Site
                  Specifications,  however,  such verification  shall not confer
                  any  responsibility  on the part of the  Contractor  for floor
                  loadings or hazardous materials;

            (ii)  obtain all landlord consents,  planning  permissions,  Permits
                  and Wayleaves necessary for refurbishment of the POP Sites and
                  the  conversion  thereof,  if applicable  (other than building
                  permits which will be procured by the  Contractor) to the uses
                  envisioned by this Contract; and

            (iii) secure all other consents and approvals,  if any, necessary to
                  allow  Contractor  Persons  to  enter  upon  such POP Site and
                  commence the Work to be  performed  thereon on or prior to the
                  date specified in the Milestone  Schedule for the commencement
                  of such Work.

     The  Contractor  shall  review  all POP Site  specifications,  records  and
     documents  supplied by the  Developer  and shall notify the  Developer,  no
     later than ten (10) Business  Days after its receipt of the relevant  data,
     of its consent, not to be unreasonably  withheld,  to the proposed POP Site
     (PROVIDED,  that the Contractor  shall not be entitled to any such right of
     consent   with  respect  to  the   selection  of  POP  Sites   procured  or
     contractually  committed to by the Owners, or by the Developer on behalf of
     such Owners,  on or before the  effective  date of this  Contract).  As the
     Contractor's   review  of  proposed  POP  Sites  shall  not  encompass  any
     assessment  of  potentially  hazardous  materials  or floor  loadings,  the
     Contractor's consent to any POP Site shall not be construed as its approval
     with respect tosuch matters.  In the event that the Contractor is unable to
     grant  its  consent  to any such  Developer  proposal,  it shall  provide a
     written  statement  identifying,  by  specific  reference  to the  relevant
     sections of the POP Site  Specifications,  the  reasons  for its  rejection
     thereof. The Contractor shall, in


                                       13
<PAGE>

     accordance  with and  subject  to  Section  15.1  hereof,  be  entitled  to
     appropriate  adjustments  through a  Contract  Variation  for any  material
     Owner-Caused Delays associated with the Developer's selection (on behalf of
     the Owners) of  acceptable  POP Sites,  or if any such POP Site selected is
     subsequently  found to contain  hazardous  materials or  substandard  floor
     loadings rising to the level of Owner-Caused Delay.

      (b)   OWNER SPECIFICATIONS. Included as part of the Technical Requirements
            are Owner  Specifications  that provide (subject to the remainder of
            this Section 8.2(b)),  with respect to the POP Sites and in relation
            to items of equipment, materials and services to be furnished by the
            Owners  (whether  acting  directly or by and through the  Developer)
            hereunder,    detailed    specifications    therefor   (the   "OWNER
            SPECIFICATIONS")    containing   sufficient   technical   data   and
            instruction  to enable the Contractor to complete each Outside Plant
            in accordance  with the Technical  Requirements.  From time to time,
            the  Developer  may  provide on behalf of the Owners  modifications,
            clarifications  or  additions  to  the  Owner  Specifications.   The
            Contractor shall comply in all respects with and be entitled to rely
            upon such Owner  Specifications,  as modified, in the performance of
            the Work.  The Owners shall be  responsible  (to the extent of their
            respective  ownership  interests  in the  Outside  Plants)  for  the
            overall  network  design for the System,  including  the  selection,
            configuration  and  integration  of System  components.  The  Owners
            shall, in accordance with their pro rata ownership  interests in the
            Outside Plants  indemnify the Contractor from and against any Losses
            to the extent arising from any infringement or claimed  infringement
            of patent,  copyright or other  industrial or intellectual  property
            rights by reason of the  Contractor's  use, in  accordance  with the
            terms and conditions of this Contract, of the Owners' overall system
            design or Owner-supplied or  Owner-supplied  technology,  design and
            equipment.  To the  extent  that  any  modifications  to  the  Owner
            Specifications  purport  to require a change in the scope of Work as
            set forth in the Technical  Requirements,  the applicable Guaranteed
            RFS  Date(s)  shall be  equitably  adjusted  pursuant  to a Contract
            Variation  subject to Section  15.1 hereof.  In the event,  however,
            that the Contractor determines, in respect of any item of Work, that
            (x) an Owner Specification  conflicts with any Vendor  Specification
            or other  Technical  Requirement,  or (y) any technical  information
            needed  by the  Contractor  for due  performance  of the Work is not
            accurately or comprehensively  set forth in the Contract  Documents,
            it shall immediately apply to the Developer for instruction  thereon
            and shall not  continue  such Work  until it has  received  an Owner
            Specification  with respect  thereto.  The  Contractor  shall not be
            entitled to receive any payment for Work performed in  contravention
            of the preceding sentence.

8.3.  THE DEVELOPER'S  REVIEW AND APPROVAL.  The Developer hereby undertakes to,
      as  expeditiously as possible (but in no event later than the dates herein
      specified therefor), to (i) review and approve all items of Work complying
      with the Contract  Documents for which such approval is required hereunder
      and,  (ii)  in  relation  to  any  application  for,  or  granting  of any
      authorizations  or rights of way  (including any  Wayleaves,  Permits,  or


                                       14
<PAGE>

      other rights and interests in the Sites and the Systems)  required for the
      installation  of Outside Plant  components,  review,  approve and sign all
      relevant documentation  conforming to this Contract submitted to it by the
      Contractor  (unless  the  Contractor  is  duly  authorized  to sign on the
      Owners' behalf) and take such other steps that may be necessary (including
      the  payment  of any fees,  premiums  or rents)  in  connection  with such
      applications,   authorizations   and  grants   hereunder.   The  Developer
      recognizes  that such  expeditious  review and approval is critical to the
      Contractor's  completion  of the Work in  accordance  with  the  Milestone
      Schedule,  and the Developer acknowledges that its unreasonable refusal or
      delay with  respect to  conforming  Work may  entitle  the  Contractor  to
      schedule  relief  pursuant  to  Contract  Variations.   In  addition,  the
      Developer  shall  use   commercially   reasonable   efforts  to  meet  the
      Contractor's  requests for  accelerated  review of all  submissions to the
      Developer  conspicuously  marked  "Urgent - For Expedited  Review" or with
      words of similar effect.

8.4.  OWNER PERMITS. The Owners shall, at their own expense and in proportion to
      their  respective  ownership  interests,  procure and  maintain  the Owner
      Permits.

8.5.  ACCESS TO OWNER FACILITIES. The Developer shall grant or obtain permission
      for Contractor  Persons to enter into Owner  facilities  forming a part of
      the Systems to perform items of Work hereunder.

8.6.  COOPERATION AND NON-INTERFERENCE  WITH WORK. The Developer shall cooperate
      with, and refrain from interfering  with, the Contractor  Persons in their
      performance of the Work,  and the Developer  shall cause all Owner Persons
      to so cooperate and refrain from such interference.

8.7   NO  DIMINISHMENT.  The  Contractor's  responsibility  for the  design  and
      installation of each Outside Plant shall not in any way be diminished, nor
      shall the  Contractor's  design approach be restricted or limited,  by any
      Owner Person's:

      (a)   acceptance of the  Contractor's  guidance or  recommendations  as to
            engineering standards and design specifications;

      (b)   suggestions  or  recommendations  on any aspect of the design of any
            part of the Outside Plants,  except to the extent  specifically  set
            forth  in any  Vendor  Specification  or in an  Owner  Specification
            expressly marked as such;

      (c)   acceptance  or  approval  of any  portion of the Work  delivered  in
            connection therewith; or

      (d)   acceptance or approval of any Subcontractor.

                   SECTION 9. MAINTENANCE OF BOOKS AND RECORDS

9.1.  MAINTENANCE OF RECORDS.  The  Contractor  shall compile and shall maintain
      for a period ending upon the later of:

      (a)   three (3) years after the RFS Date; and


                                       15
<PAGE>

      (b)   the date on which no claim based upon,  arising out of or related to
            this Contract is outstanding,

      all books, records,  vouchers and accounts pertaining to this Contract and
      the Work, including such books, records,  accounts and vouchers related to
      the  Contractor's   payments  to  Subcontractors   and  the  Reimbursement
      Invoices.

      All such books,  records,  vouchers and accounts  shall be  maintained  in
      accordance  with generally  accepted  accounting  principles and practices
      consistently  applied,  and shall, upon the Developer's prior instruction,
      be organized to allow for  segregation  of System  investment  and related
      records as the  Developer  may direct.  At the  Developer's  request,  all
      records  required to be  maintained  pursuant to this Section 9.1 shall be
      delivered  to the  Developer  on  Final  Acceptance,  in  which  case  the
      Contractor  shall be  entitled  to keep  copies  thereof  (subject  to its
      confidentiality obligations under Section 42 hereof). The Contractor shall
      maintain its customary  fiscal  records and books of account in accordance
      with generally accepted accounting  principles and practices  consistently
      applied. Nothing contained herein shall give any Owner Person the right to
      audit or examine the actual costs incurred by the Contractor  with respect
      to any  Reimbursable  Costs for which the  Owners  have  agreed to pay the
      rates specified on Table (1-A) to Appendix 1 to this Contract.

9.2.  ACCESS TO  RECORDS.  The  Contractor  shall,  during  the  period in which
      Contractor is required to compile and maintain  books,  records,  vouchers
      and  accounts  pursuant  to Section  9.1  hereof,  give each Owner  Person
      access,  at the times and in such a manner as the Developer may direct, to
      all documentation and records required to be kept, obtained and maintained
      pursuant to Section 9.1 hereof;  PROVIDED,  HOWEVER,  that with respect to
      all such books,  vouchers,  documentation and records created prior to the
      execution date of this Contract (the "PRE-CONTRACT EXECUTION PERIOD"), the
      Contractor  shall  provide all such  material to the Owner  Persons to the
      extent  and in the  form it  exists  and to  provide  it in a  format  the
      Developer or such Owner Person may  reasonably  request,  to the extent to
      which it has not  previously  been  delivered.  The  Contractor  shall not
      destroy any such  documentation or records without affording the Developer
      an  opportunity  to review or copy the same. At the  Developer's  request,
      prior  to  Final  Acceptance,  copies  of all  documentation  and  records
      required  to be kept,  obtained  and  maintained  pursuant  to Section 9.1
      hereof shall be delivered to the Developer (subject to any confidentiality
      obligations under Section 42 hereof).

      Notwithstanding  any of the  foregoing,  with respect to the  Pre-Contract
      Execution  Period,  the Contractor  shall be relieved of any obligation to
      provide any Owner Person with access to or copies of  documentation of the
      nature set forth in Section 9.1 hereof that were not in  existence  during
      the Pre-Contract  Execution Period. To the extent that such  documentation
      was  in  existence  during  the  Pre-Contract   Execution  Period  and  in
      Contractor's possession,  the provisions of the first paragraph of Section
      9.1 hereof shall apply to such documentation.

9.3.  SUBCONTRACTORS.  The Contractor shall obtain from its Subcontractors  such
      supporting  records,  as  applicable,  in form and  substance  similar  to
      thoserequired of the Contractor


                                       16
<PAGE>

      under Section 9.1 above,  and the Contractor shall maintain such records
      for the period referred to in Section 9.1 above.

                                SECTION 10. TAXES

10.1. GENERAL.  The Owner  acknowledges  that Taxes in respect of the Work shall
      constitute Reimbursable Costs, and that any Taxes actually paid in respect
      of any Subcontractor  Services or Subcontractor  Supplies shall constitute
      Subcontractor Costs.

10.2. EXEMPTION  FROM TAXES.  The  Parties  shall take  commercially  reasonable
      measures   (including,    without   limitation,   the   accommodation   of
      Tax-efficient   Owner  Person   entity   structures   and   title-transfer
      arrangements)  to have all items of Work made exempt from all Taxes (or to
      maximize  later  refunds or credits  in respect of Value  Added  Taxes and
      other  Taxes  already  assessed  or  paid),  whether  in the  procurement,
      assembly or  installation  thereof,  and shall  cooperate  fully with each
      other in this respect.

10.3. WITHHOLDING.  With  respect to any Tax  payable or assessed in relation to
      any payment due to the Contractor, the following procedures shall apply:

      (a)   If the Developer or any Owner:

            (i)   receives  a  notice,  order or  instruction  from a  competent
                  Governmental  Authority  that a Tax is required to be withheld
                  by Law; or

            (ii)  otherwise has a reasonable  belief that any Tax is required to
                  be withheld from any payment due to the Contractor,

            then the  Developer  (acting for itself or on behalf of the relevant
            Owner) shall  promptly so inform the Contractor as far in advance of
            any proposed withholdings as practicable.

      (b)   If  any  requirement  to  withhold  Tax  becomes   applicable,   the
            Contractor  shall  obtain  documentary  evidence  from the  relevant
            taxing authorities reasonably satisfactory to the Developer that the
            Developer (or relevant  Owner) is not required to withhold such Tax.
            If the Contractor is unable to obtain such documentary evidence on a
            timely basis,  then the Developer (or relevant  Owner) shall proceed
            to  withhold  any such  Tax via an  escrow  agent or other  mutually
            agreeable procedure.  Thereafter,  the Developer (or relevant Owner)
            shall, at the  Contractor's  expense,  provide any  documentation or
            other  cooperation as may be reasonably  requested by the Contractor
            to permit the  Contractor  to recover any withheld  amounts to which
            the Contractor is entitled.

10.4. INDEMNITY.  The Contractor  shall protect,  defend,  indemnify in full and
      hold  harmless  each Owner  Person from and against any Losses based upon,
      arising  out of or  otherwise  related  to  Taxes  that  are  owed  by the
      Contractor to any taxing authority.

                                  SECTION 11.  INTELLECTUAL PROPERTY RIGHTS

11.1. GENERALLY. The Parties hereby acknowledge and agree that:

     (a)  the Developer  shall  furnish on behalf of the Owners,  and the Owners
          shall  be  solely  responsible  (to  the  pro  rata  extent  of  their
          respective   ownership  interests  in  the  Outside  Plants)  for  the
          procurement of intellectual  property  rights,  if any,  sufficient to
          realize  the goals  contemplated  by this  Contract  relating  to, the
          Owner-Procured   Equipment,  the  Vendor  Specifications,   the  Owner
          Specifications   and  the  overall  network  design  for  the  Systems
          (including  the  selection,  configuration  and  integration of System
          components),  and  that the  Owners  shall  (to such pro rata  extent)
          indemnify,  protect,  defend and hold harmless the Contractor from and
          against all Losses based upon, arising out of, or otherwise related to
          an infringement or claimed infringement of patent,  copyright or other
          industrial  or   intellectual   property   rights  by  reason  of  the
          Contractor's  possession  or use of such Owner- or  Developer-supplied
          items in its performance of the Work; PROVIDED, that (i) the Developer
          shall bear no such indemnity  liability  hereunder,and (ii) the Owners
          shall be under no  indemnity  obligation  with  respect  to any Losses
          arising out of or relating to any  Contractor  Person's  possession or
          use of any such item in a manner or for a  purpose  inconsistent  with
          terms of this Contract or any Contract Document; and

      (b)   with respect to all items other than as  addressed in the  preceding
            clause (a) of this Section  11.1,  the  Contractor  (i) grants to or
            shall  cause the  respective  owners of such  intellectual  property
            rights  to grant to  Developer  and the  Owners  all  other  patent,
            copyright  and other  industrial  or  intellectual  property  rights
            applicable  to  the  Work  or  necessary  for  completion,  use  and
            operation  of each Outside  Plant or any part thereof in  accordance
            with  this  Contract  (and  all  costs  incurred  by the  Contractor
            relating to this clause (i) shall be Reimbursable  Costs hereunder),
            and (ii) in  connection  with  clause  (i) above,  shall  indemnify,
            protect, defend and hold harmless each Owner Person from and against
            all Losses based upon,  arising out of, or  otherwise  related to an
            infringement or claimed  infringement of patent,  copyright or other
            industrial or  intellectual  property  rights by reason of any Owner
            Person's  possession,  enjoyment  or use of the Work or the  Outside
            Plants  or any part  thereof.  Notwithstanding  the  foregoing,  the
            Contractor  shall be under no obligation to indemnify  Owner Persons
            with respect to any Losses  relating to any  infringement or claimed
            infringement where the assembly, installation, possession or use for
            which  infringement  is claimed was  undertaken by the Contractor at
            the Developer's express written instruction or direction. The Owners
            (to the pro rata extent of their respective  ownership  interests in
            the  Outside  Plants)  shall,  in such  cases,  indemnify  and  hold
            harmless the  Contractor  from and against any Losses so incurred by
            the Contractor at the Developer's written direction.

11.2. INJUNCTION.  If, as a  consequence  of any  action or claim  described  in
      Section  11.1 hereof,  the use of either  Outside  Plant is enjoined,  the
      Party  subject to the  indemnity  obligation  therefor  shall use its best
      efforts to negotiate with the claimant so as to remove such  injunction or


                                       18
<PAGE>

      to obtain for the Developer,  the Contractor or the relevant Owner(s),  as
      the case may be, a license or other  agreement in respect  thereof as soon
      as possible.  If such  responsible  Party is unable to have the injunction
      removed,  and such Party is (i) the Contractor,  it shall be liable to the
      Owners for any and all Losses arising as a result of such  injunction,  or
      (ii) the  Developer  (or any Owner or all of them),  the  Developer  shall
      execute and deliver to the  Contractor,  in accordance with and subject to
      Section 15.1 hereof, a Contract  Variation  providing for equitable relief
      to Contractor in respect of the material  impact upon the  Guaranteed  RFS
      Date(s) caused by such injunction on the Work.

11.3. INFRINGEMENT  ORDER.  Except to the extent relating to the  Owner-Procured
      Equipment, the Vendor Specifications and the Owner Specifications,  in the
      event that either  Outside Plant or any part thereof is held to constitute
      infringement  and is subject to an order  restraining its use or providing
      for its surrender or destruction,  the Contractor shall at its own expense
      promptly  (but  in  no  event  later  than  sixty  (60)  Days  after  such
      injunction, or such shorter period imposed by any claimant) either:

      (a)   procure  for the  Developers  and the Owners the right to retain and
            continue to use the affected portions of the Outside Plant; or

      (b)   modify  the  Outside  Plant so that it becomes  non-infringing  in a
            manner acceptable to the Developer.

11.4. NEW  DEVELOPMENTS  BY THE  CONTRACTOR.  If, in  performing  the Work,  the
      Contractor  develops any new items or processes  that are  independent  of
      items or processes developed by the Contractor  otherwise than pursuant to
      this Contract,  any  intellectual  property rights therein shall belong to
      the Owners (pro rata in accordance with their  ownership  interests in the
      Outside   Plants),   and  the  Contractor   shall  have  a   non-exclusive
      royalty-free license to use the same for any purpose.

11.5. THE CONTRACTOR'S EXISTING INTELLECTUAL PROPERTY. All intellectual property
      rights in items or processes  developed by the  Contractor  otherwise than
      pursuant to this Contract shall remain the property of the Contractor, but
      to the extent  that the  Contractor  uses any such items or  processes  in
      performing  the Work,  the  Owners  (pro  rata in  accordance  with  their
      ownership  interests in the Outside  Plants)  shall have a  non-exclusive,
      royalty-free  license to use the same for any purpose  connected  with the
      Systems, including the right to grant sub-licenses for any such purpose.

      (c)   PAYMENTS  GENERALLY.  Neither the Developer nor any Owner shall have
            any  obligation  to pay  for any  portion  of the  Work  that is not
            complete or has a Defect;  and all amounts invoiced pursuant to this
            Section 12.4 shall be:

            (i)   subject to  appropriate  inspection  by the  Developer  or its
                  designee  of any  Work  tendered  by the  Contractor  and  the
                  Developer's determination in accordance with Sections 12.6 and
                  13 hereof;

            (ii)  due and payable [REDACTED] Days after the earlier of:

                  (A)   the date that the  Contractor  provides the  Developer a
                        copy of the  Contractor  Invoice by facsimile  (PROVIDED
                        that the original Contractor Invoice is delivered to the
                        Developer within one week thereafter); or

                  (B)   the  date  that  the  Developer  receives  the  original
                        Contractor Invoice.

      (d)   OWNER  ESCROW.  The  Owners  shall,  on or before  March  31,  1999,
            establish for the benefit of the Contractor,  an escrow account (the
            "OWNER  ESCROW")  on terms  substantially  in the form of  EXHIBIT 7
            hereto and with a bank  reasonably  acceptable to the  Contractor as
            security  for payments  for the Work.  The Owners shall  maintain in
            such Owner Escrow,  for each relevant period,  the amounts set forth
            in APPENDIX 10 hereto (as such  amounts may be revised  from time to
            time  pursuant to the Owner Escrow  Agreement).  The Owners shall be
            entitled to withdraw  from the Owner  Escrow any amounts that are in
            excess of the  required  amount  specified in APPENDIX 10 hereto (as
            such  required  amount may be revised from time to time  pursuant to
            the Owner  Escrow  Agreement).  If the Owners,  or the  Developer on
            behalf thereof, request the Contractor to review proposed changes to
            the Owner Escrow,  the Contractor  shall respond to any such request
            within [REDACTED]  following receipt of such request. The Contractor
            shall be entitled to have a security  interest in the Owner  Escrow.
            Prior to  exercising  any  rights  against  the  Owner  Escrow,  the
            Contractor  shall  notify  the  Developer  and each  Owner  that the
            Developer  has  failed to pay on behalf of the  Owners,  within  the
            period specified for such payment,  an amount due and payable to the
            Contractor in respect of a Contractor  Invoice duly submitted by the
            Contractor in accordance with this Section 12. The Developer  shall,
            to the extent that no Event of Default nor other event entitling the
            Developer to withhold payments to the Contractor has occurred and is
            continuing,  reimburse the requested  amount on behalf of the Owners
            to the  Contractor  by  the  close  of  business  on the  [REDACTED]
            Business Day next succeeding the Contractor's Notice,  whereupon the
            Developer's  failure to do so, shall entitle the  Contractor to draw
            upon the Owner  Escrow in the  amount of such  outstanding  payment.
            Upon the Contractor's exercise of any rights


                                       23
<PAGE>

            against the Escrow Account in accordance with this Section  12.4(d),
            the  Owners  shall,  within  [REDACTED]  Business  Days  thereafter,
            deposit  (in  accordance  with  such  Owners'  respective  ownership
            interests  in the  Outside  Plants)  funds  in an  aggregate  amount
            sufficient  to restore  the  balance  of the  Escrow  Account to the
            required  amount  specified in APPENDIX 10 hereto (as such  required
            amount may be revised from time to time pursuant to the Owner Escrow
            Agreement),  for the date on which  such  funds  are  restored.  Any
            failure by the Owners to so  replenish  the Owner Escrow to the full
            required  balance  thereof  within such  [REDACTED]  period shall be
            deemed an Owner Default for purposes of Section 24.4 hereof.

                  Subcontractor  Cost  (including all prior payments made to the
                  relevant  Subcontractor  in  respect  thereof)  in  excess  of
                  [REDACTED]  for  which  reimbursement  is  sought;   PROVIDED,
                  HOWEVER,   that  if  the   Contractor  has  certified  in  its

                  this   clause   (ii),   that   it  will   pay   the   relevant

                  its payment to the Subcontractor(s).

                  Notwithstanding  anything contained in this clause (ii) to the
                  contrary,  at the  request of the  Developer,  the  Contractor
                  shall submit the documents  referred to in (2) and (3) of this
                  clause (ii) without regard to whether the Subcontractor  Costs
                  are less than [REDACTED] for which  reimbursement is sought if
                  the   Subcontract   or   Subcontracts   associated   with  the
                  Developer's  request  are still open and have not been  closed
                  out as a  result  of the  completion  of the  Subcontractor(s)
                  work.

                  The Contractor  shall  indemnify in full and hold harmless the
                  Developer and the Owners from and against any Losses  suffered
                  or incurred by the  Developer or the Owners  arising out of or
                  related to instances  wherein the  Contractor has certified to
                  the Developer  that it will pay the relevant  Subcontractor(s)
                  when  due  or  that  it  will   furnish   the   lien   release
                  certification  from such  Subcontractor(s)  within  [REDACTED]
                  after  the   Contractor   has  effected  its  payment  to  the
                  Subcontractor(s) and the Contractor either has not effectuated
                  such payment when due or at all or has not provided  such lien
                  release  certification  within [REDACTED] after the Contractor
                  has effected its payment to the Subcontractor(s) or at all.

                  Notwithstanding   the   foregoing,   with   respect   to   the
                  Pre-Contract   Execution  Period,   the  Contractor  shall  be
                  relieved  of the  obligation  to provide  the  Developer  with
                  documentation of the nature set forth in this clause (ii) that
                  (A) was not in  existence  during the  Pre-Contract  Execution
                  Period  and (B) cannot be  procured  by the  Contractor  using
                  Prudent  Practices.  To the extent that such documentation was
                  in existence during the  Pre-Contract  Execution Period or can
                  be procured by the  Contractor  using Prudent  Practices,  the
                  provisions   of  this   clause   (ii)  shall   apply  to  such
                  documentation.

                  within a  reasonable  time after the  Contractor's  submission
                  thereof  for  signature)  - One (1)  original  and  three  (3)
                  copies; and

                  Developer shall request.

12.6. THE DEVELOPER'S RIGHT TO WITHHOLD PAYMENT.

      (a)   GENERALLY. Notwithstanding the foregoing, the Developer may withhold
            any payment or other  amount due to the  Contractor  hereunder in an
            amount  and to such  extent as the  Developer  may  determine  to be
            reasonably  necessary  to protect the Owners from any Loss or damage
            reasonably  determined by the Developer to exceed the then-available
            funds under the Contractor Security because of:

            (i)   Defective Work not remedied in accordance with this Contract;

            (ii)  Work that has been paid for and is not complete;

            (iii) the Contractor's failure to comply with any Warranty;

            (iv)  the  Contractor's  failure to perform  the Work in  accordance
                  with this Contract;

            (v)   third-party suits, stop notices, attachments,  levies or Liens
                  (other than Owner Liens) against  either  Outside  Plant,  the
                  Work or any Party resulting from the  Contractor's  failure to
                  perform its obligations in accordance with this Contract;

            (vi)  Losses or other damage to any Owner or any Subcontractor  that
                  results  from the  Contractor's  failure to obtain or maintain
                  insurance required hereunder;

            (vii) the  Contractor's  failure to  provide  on a timely  basis the
                  documentation required under Section 12 hereof; or

            (viii)reasonable   evidence   that  any  payment   previously   made
                  hereunder  (together  with  all  other  previously   requested
                  amounts)  exceeds the amount  payable with respect to the Work
                  actually performed.

            In the Notice to the  Contractor  referenced  above,  the  Developer
            shall set forth its justification  for the proposed  withholding and
            provide the Contractor  with a [REDACTED]  period to cure the matter
            (or agree in  principle  with the  Developer  on a plan for remedial
            action with respect thereto) giving rise to the proposed withholding
            prior to the implementation thereof.


                                       26

      (b)   THE DEVELOPER'S  APPLICATION OF FUNDS  WITHHELD.  The Developer may,
            upon Notice to the  Contractor  of its intention to do so, apply any
            funds withheld or moneys to become due to the Contractor to satisfy,
            discharge or secure the matters set forth in Section  12.6(a)  above
            if the  Contractor  has continued to fail to cure such matter within
            [REDACTED]  after  Notice by the  Developer  as  provided in Section
            12.6(a) above. Any such  application  shall be deemed payment to the
            Contractor.  No action by either Party  during the above  activities
            shall affect the Milestone  Schedule unless a Contract  Variation is
            agreed  to by the  Developer.  If  the  Developer's  withholding  is
            determined  to be  wrongful,  the  Developer  shall  promptly pay on
            behalf of the Owners the withheld  amount with  interest at the rate
            set forth in Section 12.7 from the due date  thereof  until the date
            of payment.

      (c)   RELEASE  OF  PUNCH  LIST  RESERVE.   Within   [REDACTED]  after  the
            Contractor  has,  to  the  Developer's  satisfaction,  remedied  the
            deficiencies and completed the Work indicated on any Punch List, the
            Developer  shall  release to the  Contractor  the Punch List Reserve
            held by the  Developer  in respect of such  incomplete  or Defective
            Work.

12.7. OVERDUE  PAYMENTS.  If a party  shall  fail to pay any  undisputed  amount
      within  [REDACTED] after the due date for such payment,  such amount shall
      accrue  interest,  at a rate  equal to the lesser of (i) the one (1) month
      London  Interbank  Offered Rate for Euros (as published for such period in
      THE FINANCIAL  TIMES) PLUS [REDACTED]  percent  ([REDACTED]%)  or (ii) the
      maximum  interest rate permitted by applicable Law, for each day from such
      due date until payment in full.

             SECTION 13. DEDUCTIONS FROM PAYMENTS TO THE CONTRACTOR

13.1. AMOUNTS  PAYABLE.  To the extent that an amount is not withheld in respect
      thereof  pursuant to Section 12.6 hereof or has not been drawn or obtained
      for the Owners'  benefit under any  Contractor  Security,  all Losses that
      Owner  Persons  shall have incurred or sustained by reason of any act that
      entitles the Owners to indemnification  under this Contract or any default
      or  omission  of the  Contractor  in the  performance  of  this  Contract,
      together  with any sum or sums payable to the  Developer  (for the Owners'
      account) under this Contract,  shall be paid by the Contractor on or prior
      to the earlier of:

      (a)   the  date  that  is  [REDACTED]  after  receipt  of the  certificate
            referenced in Section 13.3 hereof; and

      (b)   the date the Final Payment is made.

13.2. DEDUCTION.  Should the Contractor fail to make any payment  required under
      Section 13.1 hereof by the due date thereof, the Developer may then deduct
      the  amount of the  requested  payment  from any moneys  that are,  or may
      become,  due to the Contractor or have been made available by it under any
      Contractor Security.  If the moneys so due or deposited shall be less than
      the amount so deductible, the difference shall be treated as a debt by the
      Contractor to the Owners (the collection of which to be carried out by the
      Developer)  and shall be paid by the  Contractor to the  Developer  within


                                       27
<PAGE>

      [REDACTED]  after  the  Contractor's  receipt  of the  Developer's  demand
      therefor. If the Contractor fails to make such payment within such period,
      then the  amount  of such  deficiency  may be  recovered  in any  court of
      competent jurisdiction.

13.3. CERTIFICATE.  A certificate  signed by the Developer stating the amount of
      the Losses, costs, charges, expenses, damages or other amounts referred to
      in this Section 13 shall be PRIMA FACIE evidence of the matter stated.

                               SECTION 14.  CONTRACTOR SECURITY

14.1. GENERALLY.  In  addition  to the  Contractor's  security  provided  by the
      Retainage  LC as set forth in  Section  12.4(a),  the  performance  of the
      Contractor's  obligations under this Contract shall also be secured by the
      following:

      (a)   the Corporate Guarantee, which shall be delivered on or before April
            15, 1999 and remain in effect  until the Final  Acceptance  Date and
            shall secure the  Contractor's  unconditional  obligation to achieve
            RFS Acceptance of each Outside Plant; and

      (b)   a performance  and payment  surety bond in  substantially  the form,
            with such changes as the issuer  thereof may  require,  of EXHIBIT 2
            hereto (the "CONTRACTOR SURETY BOND") which shall be delivered on or
            before August 1, 1999 and shall secure the performance of all of the
            Contractor's obligations under this Contract.

14.2. FORM OF CONTRACTOR SURETY BOND. The Contractor Surety Bond shall:

      (a)   be issued  and  outstanding  until  the date on which the  Developer
            issues the  Certificate of RFS Acceptance in respect of the later of
            the two Outside Plants to achieve RFS Acceptance;

      (b)   be in an amount equal to [REDACTED]; and

      (c)   name the Developer,  each Owner or their  respective  successors and
            permitted assigns as beneficiaries thereof.

14.3. ISSUER  REQUIREMENTS.   The  Contractor  Surety  Bond  and  all  renewals,
      extensions  and  replacements  thereof  shall be issued  by a  bonding  or
      insurance company acceptable to the Developer at the time of issuance.  If
      the financial  condition of any such bonding or insurance company declines
      to less than an A.M. Best rating of A, the Contractor  shall,  at its sole
      cost and  expense,  within  thirty  (30) Days  after any such  decline  in
      rating,  replace the issuer of the  Contractor  Surety Bond with an entity
      acceptable to the Developer;  PROVIDED that if the Contractor  Surety Bond
      is provided by more than one  bonding or  insurance  company and each such
      company is jointly and severally liable thereunder,  the highest rating of
      any one of such companies shall be controlling.

                         SECTION 15. CONTRACT VARIATIONS

15.1. EQUITABLE  RELIEF.  The parties shall be entitled to equitable relief with
      respect  to  the   requirements   of  this   Contract  in  the   following
      circumstances  and in accordance  with the following  procedures (any such
      equitable  relief in accordance  with this Section 15 shall be recorded by
      means of a formal writing (a "CONTRACT  VARIATION") agreed to between, and
      executed  by,  the  Parties in  accordance  with the  procedure  set forth
      herein):

      (a)   ADJUSTMENT TO GUARANTEED  RFS DATES.  If the  Contractor is, despite
            the exercise of Prudent  Practices  and through no fault or omission
            of any Contractor  Person,  delayed in its  performance of the Work,
            the Contractor  may, to the extent that such delays result  directly
            from any Change Event or any change or addition to the general scope
            of this Contract or change to the method or manner of performance of
            the Work as  instructed  by the  Developer  on behalf of the  Owners
            (such instructions, "OWNER-REQUESTED VARIATIONS") or any combination
            of Change Events or  Owner-requested  Variations,  be entitled to an
            adjustment to the applicable Guaranteed RFS Date(s). Notwithstanding
            anything to the contrary set forth herein,  the Contractor  shall be
            entitled  to  a  Contract   Variation   executed  and  delivered  in
            accordance  with this Section 15.1(a) with respect to the applicable
            Guaranteed  RFS Date only to the extent that its  performance of the
            Work is  materially  delayed or is likely to be  materially  delayed
            (despite the  Contractor's  use of Prudent  Practices in  mitigation
            thereof)  by any  Change  Event or  Owner-requested  Variations  (or
            combination thereof).

      (b)   ADJUSTMENT TO FIXED FEE OR INCENTIVE FEES IN LIMITED  CIRCUMSTANCES.
            The  Developer  may from time to time issue  written  notices to the
            Contractor  directing  additions to,  revisions to or deletions from
            the scope of Work under this  Contract.  The  Contractor  shall give
            immediate  effect to each such  notice;  PROVIDED,  that such notice
            shall in no way limit the  Contractor's  entitlement to Reimbursable
            Costs in  respect of Work  performed  by the  Contractor  in its due
            prosecution of the Work prior to the Developer's notice of additions
            to,  deletions or  reductions of the relevant  item(s) of Work.  The
            Fixed  Fee and  Incentive  Fees  referred  to in  Sections  12.2 and
            12.2(a) and (b) hereof shall be subject to  adjustment in accordance
            with this  Section  15.1(b) by adjusting  the Target  Cost,  and the
            Incentive  Fees  referred  to in  Section  12.2(c)  hereof  shall be
            subject to  adjustment in  accordance  with this Section  15.1(b) by
            adjusting  the  Total  Completion  Cost  column in the table in such
            Section 12.2(c),  in each case only in the following  circumstances:
            (i) the  addition or deletion of a POP or (ii) the addition of a new
            point-to-point  route (e.g., a proposed Hamburg to Hanover to Bremen
            POP route) to the Detailed  Cable Routing  described in Table 2-B of
            Appendix  2. In the  case  of an  additional  POP or  point-to-point
            route,  the amount of the  increase  in the Target Cost shall be the
            Reimbursable  Costs  incurred in the Work. If a POP is deleted,  the
            Target Cost will be decreased by the  unexpended  amount  associated
            with the deleted  POP  remaining  in the  then-current  budget.  The
            Target Cost (or Total Completion Cost column in the table in Section
            12.2(c)), as so adjusted, will be set forth in a Contract Variation.

15.2. PROCEDURE FOR IMPLEMENTING CONTRACT VARIATIONS.  In the event that a Party
      wishes to claim any  equitable  relief  hereunder on account of any Change
      Event,  such Party shall give the other Party written notice of its intent
      to submit such claim (which notice shall state the basis of such claim and
      the general nature of the relief  requested)  within  [REDACTED]  after it
      becomes aware of such basis for equitable  relief.  The  submitting  Party
      shall submit to the recipient its documented and  substantiated  claim for
      such  adjustment(s) as soon as practicable  after giving such notice,  but
      not later than  [REDACTED]  after giving such notice,  unless  extended in
      writing by the submitting  Party.  Such claim shall include an estimate of
      the  impact  of such  proposed  relief on the  Guaranteed  RFS  Dates,  as
      applicable,  as supported by sufficient  costing and description detail to
      allow the recipient to make a reasonable  determination  as to such impact
      and the desirability of such relief in light of available alternatives.

      The  recipient  shall  respond  to the  submitting  Party's  claim  within
      [REDACTED]  after  receipt.  If the recipient  agrees that the  submitting
      Party's claim should be implemented,  the recipient shall issue a Contract
      Variation  incorporating such claim. If the recipient disagrees in any way
      with  the  submitting  Party's  claim  for  the  Contract  Variation,  the
      recipient  shall return the submitting  Party's claim,  marked to show the
      recipient's  modifications  thereto.  The original  submitting Party shall
      within  [REDACTED] of receipt of such mark-up,  either advise the original
      recipient of its agreement to such modifications or request a meeting with
      the  original  recipient  to resolve  any and all  disagreements  with the
      modifications  made by the  original  recipient.  If the latter  option is
      taken,  the Parties shall meet as soon as  practicable  to resolve in good
      faith  discussions  any  disagreements.  In the event that the Parties are
      unable to resolve any such dispute within [REDACTED] after commencement of
      mutual discussions in respect thereof,  such dispute shall be referred for
      resolution,  within  [REDACTED]  after  such  referral,  by  the  Parties'
      respective senior  management  personnel  directly,  or by the independent
      technical  expert  ("INDEPENDENT  EXPERT") whom they may agree to appoint.
      All matters that the Parties may desire to refer to an Independent  Expert
      shall be governed by Independent  Expert Procedures annexed as APPENDIX 11
      hereto.  The  resolutions of all  disagreements  shall be reflected in the
      Contract Variation.

15.3. EFFECT OF CONTRACT VARIATIONS.  Each Contract Variation,  to be effective,
      shall be in writing and executed by the Contractor  and the Developer.  No
      Contract  Variation shall vitiate or invalidate this Contract.  Subject to
      the  provisions of this Section 15, the  Contractor  comply with each such
      Contract Variation.

15.4. PERFORMANCE  PENDING  RESOLUTION.  If the  Parties  are unable to agree on
      certain  aspects  of  any  Contract  Variation,  at  the  request  of  the
      Developer, the Contractor shall continue to perform, pending resolution of
      the relevant matter, this Contract as provisionally modified by such terms
      of the relevant Contract  Variation as to which the Parties have evidenced
      their agreement in a writing signed by both Parties.

15.5. NO  DELAY.  In  preparing  any  proposal  for a  Contract  Variation,  the
      Contractor  shall  structure  its claims for  equitable  relief such as to
      envision  completion,  to the extent  practicable,  of the Work under this
      Contract,  as modified by the proposed Contract  Variation,  in accordance


                                       30
<PAGE>

      with  the  Milestone  Schedule.  In this  respect,  the  Contractor  shall
      cooperate with the Developer to prepare all reasonable  work-around plans,
      alternate sources or any other means available in order to prevent delays.

                         SECTION 16. OWNER-CAUSED DELAYS

16.1  GENERALLY. The following events or circumstances,  to the extent resulting
      directly in any increased delay to the Contractor in its completion of the
      Work in accordance with the Milestone  Schedule and the other requirements
      of this Contract, shall, upon the Developer's failure to effect a cure (or
      any Owner's  failure to effect such cure,  the tender of which directly by
      any Owner the Contractor  hereby agrees to accept) within [REDACTED] after
      the  Contractor's  Notice  thereof,  constitute  "OWNER-CAUSED  DELAY" for
      purposes of this Contract:

      (a)   acts or  omissions  of Owner  Persons or  Vendors of  Owner-Procured
            Equipment  (A) causing any  casualty or damage to the Systems or any

            inspection  or otherwise,  to the extent not otherwise  contemplated
            herein) with the provision of the Work;

      (b)   except to the extent that any relevant  obligation  of the Developer
            or the Owners is  governed  by  another  express  provision  of this
            Contract,  the Developer's or any Owner Person's failure to furnish,
            by the date set forth in the Milestone Schedule for the Contractor's
            commencement   of  Work   with   respect   thereto,   any   item  of
            Owner-Procured  Equipment  (including  the  Developer's or any Owner
            Person's failure to furnish items of  Owner-Procured  Equipment that
            are  free  from  defects  and   deficiencies)   or  any  information
            (including the  Developer's  failure to timely provide  accurate and
            complete  information)  that it is  required  to provide  hereunder,
            which failure, in each case (A) relates to an item that is necessary
            to the  Contractor in order to complete the Work in accordance  with
            the Milestone  Schedule and (B) continues  (without the  Developer's
            furnishing thereof or accommodation therefor) for a period in excess
            of  [REDACTED]  after  the  Contractor's  Notice  to  the  Developer
            thereof;

      (c)   any Owner Person's unreasonable refusal to review or approve, or any
            unreasonable  delay in its review,  approval,  signature or delivery
            of,  any  item  of  Work   (including,   without   limitation,   the
            Wayleave-related   documentation  specified  in  Section  7  hereof)
            complying with this Contract and Contract  Documents,  in each case,
            within the time periods  specified in this Contract for such review,
            approval, signature or delivery;

      (d)   the failure by the Developer to make available to Contractor Persons
            the Sites  (including any such failure with respect to the POP Sites
            to be made available in accordance  with Section 8.2(a)) on a timely
            basis,  or any  interruption  (except  for  purposes  of  reasonable
            inspection as envisioned by this  Contract) in the  availability  to
            the relevant Contractor Persons of any such Site caused by any Owner
            Person (including by virtue of any Owner Person's  commercial use or
            operation of the Systems or any RFCS Portion thereof); or


                                       31
<PAGE>

      (e)   the  Developer's  exercise of suspension  rights pursuant to Section
            22.1 hereof.

16.2. EFFECT.  At such time as the Developer (or any Owner,  as applicable)  has
      failed to cure any event or circumstance of Owner-Caused  Delay within the
      period specified in Section 16.1 hereof, the Contractor may be entitled to
      a  Contract  Variation,  and the  procedures  of  Section  15 shall  apply
      thereto.

                         SECTION 17. GUARANTEED RFS DATE

17.1. GUARANTEED  RFS DATE. The  Contractor  guarantees  that RFS Acceptance for
      each  Outside  Plant (or  segment  thereof)  shall  occur on or before the
      Guaranteed RFS Date for such Outside Plant (or segment  thereof),  as each
      such date may be extended in accordance with Sections 15 and 18 hereof.

17.2. [INTENTIONALLY OMITTED].

                  measures of performance; and

                  Subcontractor or (C) any of their respective agents hereunder;

            (ii)  late delivery of equipment or materials  (except to the extent
                  caused by a Force Majeure Event);

            (iii) economic hardship;

            (iv)  default of  Subcontractors  (except to the extent  caused by a
                  Force Majeure Event);

            (v)   events  and  conditions  of which  the  Contractor  is  deemed
                  hereunder to have fully informed itself; and

            (vi)  all other  events and acts failing to meet any of the criteria
                  set forth in Section 18.1(a) hereof for a Force Majeure Event.

18.2. MITIGATION.  The Contractor shall use commercially  reasonable  efforts to
      mitigate and minimize the effects of any Force Majeure Event and to resume
      in full its performance under this Contract.

18.3. NOTICE.  The Contractor  shall advise the  Developer's  Representative  in
      reasonable  detail of any Force Majeure Event within  [REDACTED]  from the
      date  of the  occurrence  thereof;  PROVIDED  that if the  Contractor  can
      satisfactorily  demonstrate  to the Developer that the Contractor has been
      unavoidably  delayed in  becoming  aware of the  occurrence  of such Force
      Majeure  Event,  such period and the time period set forth in Section 18.4
      hereof shall commence from the date reasonably determined by the Developer
      that the  Contractor  became aware,  or should have become aware,  of such
      occurrence.

18.4. APPLICATION. If the Contractor is directly delayed in the execution of the
      Work by any Force Majeure Event,  the  Contractor  shall have the right to
      apply in writing to the Developer's Representative within [REDACTED] after
      the  occurrence  of such  Force  Majeure  Event  for an  extension  of any
      Guaranteed  RFS Date or any date set forth in the Milestone  Schedule,  if
      and to the extent any such date is affected by such Force  Majeure  Event.
      Such application shall set forth a statement of all the facts on which the
      Contractor bases such an application,  including a detailed description of
      work-around  plans,  alternate  sources or any other means the  Contractor
      will  utilize to make up for any such  period of delay and to prevent  any
      further delay to the Work.

18.5. EXTENSION OF TIME.  The  extension  of time,  if any, to be allowed to the
      Contractor  pursuant  to this  Section 18 shall be set forth in a Contract
      Variation  duly  executed  and  delivered  in  accordance  with Section 15
      hereof,  and shall be for such periods as the  Developer  approves  (which
      approval  shall not be  unreasonably  withheld) as necessary to remedy the
      schedule  effects of the Force Majeure Event,  but shall in no event limit
      either Party's  rights under this  Contract,  including any Party's rights
      with  respect  to matters  arising  prior to the  occurrence  of the Force
      Majeure Event.

18.6. LIMITATION. Unless:

      (a)   an event  is a Force  Majeure  Event as  provided  in  Section  18.1
            hereof;

      (b)   the Contractor notifies the Developer thereof within the time period
            provided in Section 18.3 hereof;

      (c)   the Contractor  applies for an extension of time in respect  thereof
            within the time period provided in Section 18.4 hereof; and

      (d)   the  Developer  approves an extension of time in respect  thereof in
            accordance with Section 18.5 hereof,

      the Contractor  shall not be entitled to, and shall not claim an extension
      of time,  for such event,  except to the extent  that (i) the  Contractor,
      despite its exercise of due diligence, did not know and was unaware of the
      nature and extent of the relevant  Force Majeure  Event,  and (ii) neither
      the  Developer  nor any  Owner  was not  substantially  prejudiced  by the
      Contractor's  failure  to provide  the  notices  within  the time  periods
      referenced in items (b) and (c) above.

         SECTIOM 19. PROJECT MANAGER AND THE DEVELOPER'S REPRESENTATIVE

19.1. PROJECT  MANAGER.  The  Contractor  shall  designate  in writing a project
      manager (the "PROJECT MANAGER") to be responsible for the coordination and
      monitoring of the Work on the Contractor's  behalf,  and shall provide the
      Developer with a summary of such Project Manager's background and relevant
      experience.  The  Project  Manager  shall  act as the  principal  point of


                                       34
<PAGE>

      contact between the Contractor and the Developer, and shall have authority
      to act and make  decisions  on behalf  of,  and be  authorized  to bind by
      contract or otherwise, the Contractor. If the Project Manager shall resign
      or at any  time  be  unable  to  act,  the  Contractor  shall  immediately
      designate a successor by Notice to the Developer.

19.2. THE DEVELOPER'S REPRESENTATIVE. The Developer shall designate in writing a
      system manager (the  "DEVELOPER'S  REPRESENTATIVE")  to be responsible for
      coordination  and monitoring of the Work on the  Developer's  behalf.  The
      Developer's Representative shall provide the interface with the Contractor
      on all technical and contractual matters pertaining hereto, and shall have
      authority  to act and make  decisions on behalf of, and be  authorized  to
      bind by  contract or  otherwise,  the  Developer  (and,  accordingly,  the
      Owners). The Developer's  Representative shall from time to time authorize
      in writing Persons to carry out specific tasks on the Developer's  behalf.
      To the extent that the Developer  desires to appoint a third-party  (I.E.,
      any Person  other than an employee or  Affiliate  of the  Developer or any
      Owner) as the Developer's Representative, the Developer shall consult with
      the Contractor as to such  appointment,  providing the Contractor with the
      opportunity to make reasonable comments with respect thereto.

                          SECTION 20. INSPECTION RIGHTS

20.1. GENERALLY.  At all times during which Work is being  performed  hereunder,
      the Developer and its designees  shall,  upon reasonable  prior notice and
      within normal business hours, have full access to the Work. The Contractor
      shall provide  appropriate  facilities for such access and for the purpose
      of  inspection  and  testing  in  accordance  with the  provisions  of the
      Technical  Requirements.  The Developer and its designees shall be allowed
      full access to all plants,  offices  and Sites of the  Contractor  and its
      Subcontractors  to enable it to inspect the Work and to monitor  progress.
      The Developer and its designees shall have the right to establish resident
      representative(s)  at the Contractor's and its Subcontractors'  plants and
      at all Sites,  and, at the  Developer's  or its  designee's  request,  the
      Contractor and its  Subcontractors  shall make available  suitable  office
      space and  facilities for such  representative(s)  and, to the extent such
      office space and facilities  are not otherwise  specified in the Technical
      Requirements  as included in the Work, the Contractor may be entitled,  to
      the extent provided in Section 15 hereof, to Contract Variation in respect
      thereof  to the  extent  the  provision  of  additional  office  space and
      facilities impacts the Milestone Schedule. The Contractor shall include in
      all of its Subcontracts such provisions as may be necessary to secure such
      rights on behalf of the Developer or its designees.  The  Developer's  and
      its designee's inspection activities may include:

      (a)   an audit of the Contractor's and its Subcontractors' quality control
            system and practices and their application to the Work, including to
            the design, manufacture, transportation, installation and testing of
            the Work,  each Outside  Plant,  and all  materials  and  components
            thereof; and

      (b)   inspection  of all parts of the Work to ensure  compliance  with the
            Technical Requirements.


                                       35
<PAGE>

20.2  COVERED  WORK.  If any portion of the Work is believed by the Developer to
      have  been  covered   contrary  to  the  request  of  or  to  requirements
      specifically  expressed in this  Contract,  the  Developer  shall  provide
      Notice to the  Contractor  setting  forth  the  basis for the  Developer's
      belief and the Contractor  shall provide its written response within three
      (3) Business Days after such Notice. Any disputes shall be settled by good
      faith   discussion   amongst  the  Project  Manager  and  the  Developer's
      Representative. If the Developer is able to substantiate its position, the
      Work  involved  must,  if  required  in  writing by the  Developer  or its
      designee,   be  uncovered  for  its  observation  and  replaced,   at  the
      Contractor's  expense. If any other portion of the Work is covered and the
      Developer or its designee had not  specifically  requested the opportunity
      to inspect  such Work  prior to it being  covered  and it was not  covered
      contrary to  requirements  specifically  expressed in this  Contract,  the
      Developer or its designee may request the opportunity to inspect such Work
      and it shall be uncovered by the  Contractor.  If such Work is found to be
      in accordance  with this  Contract,  the cost of uncovering and recovering
      shall be  charged to the Owners as a  Reimbursable  Cost.  If such Work is
      found not to be in accordance with this Contract, the Contractor shall pay
      all costs of uncovering and recovering.

20.3. NO RELIEF.  Except as provided by Section  20.1, no  inspection,  audit or
      approval by or on behalf of the  Developer  or any other  Owner  Person in
      respect of any aspect of the Work shall  relieve the  Contractor of any of
      its responsibilities  under this Contract.  Notwithstanding the foregoing,
      to the extent that the Contractor is required to interrupt  performance of
      any portion of the Work on account of the  Developer's  inspection  of any
      Work found in such inspection to be in compliance with all requirements of
      this Contract,  the  Contractor  shall be entitled to an extension of time
      equal to the  duration of such  interruption,  to the extent  specified in
      Section 15.1 hereof.

                           SECTION 21. DEFECTIVE WORK

21.1. GENERALLY.  Without  limiting or impairing  the  Contractor's  obligations
      pursuant to Section 32 hereof with respect to any Defects in the Work,  if
      at any time before the relevant RFS Date, any of the Contractor's  Work is
      found to contain  Defects,  or is  otherwise  not in  accordance  with the
      Contract  Documents,  the  Developer or its designee may reject such Work,
      and the Owners shall have no liability  with respect to payment  therefor,
      notwithstanding that:

      (a)   satisfaction may previously have been expressed;

      (b)   title to such Work may have passed to the Owners in accordance  with
            Section 36 hereof;

      (c)   such Work may previously have been accepted; or

      (d)   payment may have been made in respect of such Work.

21.2. EXISTENCE  OF  DEFECTS.  A Defect  shall be deemed to exist when  actually
      discovered  or when it should have been  apparent to a prudent  contractor
      performing  the Work,  after  reasonable  inspection or testing,  that the
      relevant Work is not in conformity  with the  requirements of the Contract


                                       36
<PAGE>

      or any Contract  Document.  Each  occurrence of an alleged Defect shall be
      subject  to  expedited  review  by the  Parties  as to  whether  a  Defect
      attributable  to the  Contractor or a deficiency  attributable  to a third
      party. If the Contractor has reasonable  grounds for disagreement with any
      Developer  determination as to the existence of a Defect attributed to the
      Contractor,  such dispute shall be immediately  (but in no event more than
      two (2) Business Days after the Developer's Notice of such  determination)
      referred to deliberation amongst the Parties' senior-management  personnel
      for resolution.  If the senior-management  personnel are unable to resolve
      the  dispute  within  five (5)  Business  Days  after  such  referral  for
      resolution in accordance  with the  Independent  Expert  Procedures as set
      forth in APPENDIX 11 hereto.

                 SECTION 22. SUSPENSION OF WORK BY THE DEVELOPER

22.1. GENERALLY. Should the Developer desire, in its sole discretion, to suspend
      the whole or any part of the Work or  suspend  for a further  period  Work
      already suspended  pursuant to this Section 22, the Developer shall notify
      the  Contractor,  indicating  the  period of the  proposed  suspension  or
      further  suspension.  If the Contractor believes that such suspension will
      result in additional  costs or delay for the  Contractor,  the  Contractor
      shall, within [REDACTED] after such Notice,  furnish an itemized statement
      to the  Developer  indicating  (a) the  extension  of time  to  which  the
      Contractor   believes  it  would  be  entitled  if  the  suspension   were
      implemented,  (b) the Contractor's estimate of the additional Reimbursable
      Costs, if any, that would result from the proposed  suspension and (c) the
      Contractor's  estimate as to additional  terms of this  Contract,  if any,
      which would be affected by the proposed  suspension.  Upon receipt of such
      itemized  statement  (or if no  such  statement  is  received  within  the
      stipulated  [REDACTED],  the Developer  shall either confirm or cancel the
      proposal to suspend or further  suspend the Work or further  question  the
      Contractor on the basis of such  itemized  statement.  Promptly  after the
      Parties  agree on any  extension  of time,  they shall  execute a Contract
      Variation in respect thereof in accordance with Section 15 hereof.

      In the event that the  Developer  shall,  pursuant to this  Section  22.1,
      suspend the Work in its entirety for (i) a period of  [REDACTED],  or (ii)
      periods totaling  [REDACTED],  such suspension  shall,  upon the expiry of
      such  [REDACTED]  period,  as  applicable,  constitute a  Termination  for
      Convenience for all purposes hereof.

22.2. THE CONTRACTOR'S DUTIES UPON SUSPENSION.  During any such suspension,  the
      Contractor shall:

      (a)   cease  performance  of the  Work  and  place no  further  orders  or
            Subcontracts relating to the suspended Work;

      (b)   protect and care for all materials, equipment and supplies forming a
            part of the Work or each  Outside  Plant,  in transit to or from the
            Sites or at storage areas for which it is responsible; and


                                       37
<PAGE>

      (c)   give the Developer  copies of all  outstanding  orders and contracts
            for  materials and services and take any action with respect to such
            orders and contracts as the Developer may direct.

22.3. THE  CONTRACTOR'S  DUTIES  AFTER  SUSPENSION.  Upon the  cessation of such
      suspension,  the Contractor shall resume  performance of the Work within a
      reasonable period after being directed to do so by the Developer.

                     SECTION 23. TERMINATION FOR CONVENIENCE

23.1. TERMINATION.  The  Developer  may,  upon  written  Notice  (a  "NOTICE  OF
      TERMINATION  FOR  CONVENIENCE")  to the Contractor at any time,  terminate
      this Contract or otherwise terminate the Contractor's employment hereunder
      as  to  either  the  whole  or  part  of  the  Work  (a  "TERMINATION  FOR
      CONVENIENCE").  A  Termination  for  Convenience  shall not  nullify  this
      Contract but shall operate to terminate the Contractor's  right to proceed
      with the Work and to  discharge  the Owners from their  obligations  under
      this Contract,  except for the Owners'  obligation to pay the  Termination
      Payment (Convenience). A Termination for Convenience shall not relieve the
      Contractor from liability under applicable Law for damages for any failure
      or  omission  to  perform  any  portion  of this  Contract  prior  to such
      termination  or  prejudice  any legal  rights  of the Owner  Person or the
      Contractor, whether those rights arise under this Contract or otherwise.

23.2. TERMINATION  DATE. A Termination for Convenience  shall be effective,  and
      this Contract  shall be  terminated,  when the Notice of  Termination  for
      Convenience is delivered to the Contractor.

23.3. TERMINATION PAYMENT (CONVENIENCE).

      (a)   AMOUNT.  In the case of a Termination  for  Convenience,  the Owners
            shall make a payment to the  Contractor  (the  "TERMINATION  PAYMENT
            (CONVENIENCE)")  equal to the sum of (i) Reimbursable Costs incurred
            by the Contractor as of the Termination Date, (ii) the Fixed Fee and
            any Incentive Fee payable in accordance  with Section 12.2 hereof so
            long as the  Contractor  has  met the  criteria  for  any  such  fee
            pursuant to such Section 12.2, and (iii) the Contractor's reasonable
            and necessary  costs incurred in connection  with the termination of
            vendor orders and  Subcontracts,  demobilization  from the Sites and
            the  performance  of  its  duties  upon   termination  as  specified
            hereunder

      (b)   TERMINATION  CLAIM.  The Contractor  shall submit to the Developer a
            written termination claim (the "TERMINATION CLAIM"). The Termination
            Claim  shall  set forth a  calculation  of the  Termination  Payment
            (Convenience)  and all  other  relevant  facts,  and  shall  contain
            supporting  documentation in respect thereof.  The Termination Claim
            shall be  submitted  promptly,  but,  in any  event,  no later  than
            [REDACTED]  from the effective date of termination of this Contract;
            PROVIDED,  however,  that the Developer and the Contractor may agree
            to such additional time as may be reasonably required to compile and
            submit   such   Termination   Claim  and   gather   the   supporting
            documentation therefor.


                                       38
<PAGE>

       (c)  REVIEW  PERIOD.   Within   [REDACTED]   after  its  receipt  of  the
            Termination  Claim (the  "TERMINATION  CLAIM  REVIEW  PERIOD"),  the
            Developer  shall convey any  objections  or requests for  additional
            information  it may have with  respect to the  determination  of the
            Termination Payment (Convenience). The Contractor shall provide such
            information  to  the  Developer  as  soon  as  practicable.  If  the
            Developer objects to any portion of the Termination  Claim, it shall
            notify  the  Contractor  in  writing,  not later than the end of the
            Termination  Claim Review Period,  of each item it believes requires
            adjustment and, for not more than  [REDACTED](or  such longer period
            as the Parties may agree),  the Parties shall attempt to resolve any
            differences.

      (d)   ACCOUNTING  FIRM.  If the  Parties  are  unable to so  resolve  such
            differences within such time period,  they shall, within [REDACTED],
            jointly submit the items in dispute to a "Big Four"  accounting firm
            mutually  agreed  upon  by the  Contractor  and  the  Developer  for
            resolution on an expedited basis with a request for a written report
            thereon to be submitted  within  [REDACTED] from such submittal.  If
            the Parties cannot agree on the  determination of the accountant for
            the purposes hereof, the accountant shall be a "Big Four" accounting
            firm designated by the mutual  agreement of a "Big Four"  accounting
            firm  designated by the Developer and a "Big Four"  accounting  firm
            designated by the Contractor.  Adjustments to the Termination  Claim
            by the accountant, if any, shall be:

            (i)   made in accordance with the criteria set forth in this Section
                  23.3;

            (ii)  set forth in its written report; and

            (iii) final and  binding on the  Parties in the  absence of manifest
                  error.

            Judgment   may  be  entered   thereon   in  a  court  of   competent
            jurisdiction.  The  accountant  shall have no authority to change or
            alter the terms and conditions of this Contract.  Such determination
            by the  accountant  shall not relieve  either  Party from  liability
            under applicable Law for damages for breach of contract or prejudice
            any legal right of the  Parties,  whether  those  rights arise under
            this  Contract  or  otherwise.  The  Contractor  shall  provide  the
            accountant with access,  under  confidentiality  conditions,  to all
            books of account and records of the  Contractor  that relate to each
            Outside  Plant  and  are  relevant  to  the   determination  of  the
            Termination  Claim,  based on the criteria set forth in this Section
            23.3. The fees and expenses  incurred in connection  with any review
            by the  accountant  pursuant to this Section  23.3(d) shall be borne
            one-half by the Owners and one-half by the Contractor.

      (a)   the  Contractor  fails to (i)  carry out  engineering,  fabrication,
            supply,  delivery,  installation  and testing of the Work on or with

            accordance with the provisions set forth in Section 5.2 hereof; or

      (b)   the  Contractor  commits  any  material  breach  of, or fails in any
            material  respect to comply with and observe,  any provision of this
            Contract; or

      (c)   the  Contractor  abandons  the  Work  for  a  period  in  excess  of
            [REDACTED] or intimates  without lawful cause or justification  that
            the Work will not or cannot be completed; or

      (d)   the  Contractor  shall make a general  assignment for the benefit of
            creditors,  or any proceeding  shall be instituted by the Contractor
            seeking  to  adjudicate  it a  bankrupt  or  insolvent,  or  seeking

            protection,  relief or  composition  of the  Contractor or its debts
            under Law relating to bankruptcy,  insolvency or  reorganization  or
            relief or the  appointment  of a receiver,  trustee or other similar
            official  for  the  Contractor  or for any  substantial  part of its
            property  or the  Contractor  shall  take any  corporate  action  to
            authorize  any of the  actions  set  forth  above  in  this  Section
            24.1(d); or

      (e)   an  involuntary  petition  shall be filed or an action or proceeding
            otherwise  commenced against the Contractor seeking  reorganization,
            arrangement or  readjustment  of the  Contractor's  debts or for any
            other relief under any  bankruptcy or insolvency  act or Law, now or
            hereafter  existing and remain undismissed or unvacated for a period
            of [REDACTED]; or

      (f)   a receiver, assignee, liquidator, trustee or similar officer for the
            Contractor or for all or any part of its property shall be appointed
            involuntarily; or

      (g)   the  Contractor  shall  file  a  certificate  of  dissolution  under
            applicable  Law or shall  be  liquidated,  dissolved  or wound up or
            shall commence or have commenced against it any action or proceeding
            for  dissolution,  winding  up or  liquidation,  or  shall  take any
            corporate action in furtherance thereof; or

      (h)   the Contractor either:

            (i)   fails to make prompt payment of any undisputed  invoice due to
                  any Subcontractor or otherwise for materials or labor; or


                                       40
<PAGE>

            (ii)  repudiates  or is in  default  with  respect  to  any  of  its
                  obligations to a Subcontractor; or

      (i)   the Contractor fails, after being notified thereof by the Developer,
            to promptly  correct any Defective  Work during  performance  of the
            Work or within the Warranty Period; or

      (j)   any  representation  or warranty made by the Contractor herein or in
            any certificate,  financial statement or other document furnished to
            any Owner Person by or on behalf of the Contractor shall prove to be
            false or  misleading  in any  material  respect as of the time made,
            confirmed or furnished;

            then,  upon the  occurrence  of any Event of Default  referred to in
            paragraph  (a), (b), (i) or (j) of this Section 24.1,  the Developer
            may, by Notice in writing,  advise the  Contractor  of such Event of
            Default and the  Contractor  shall have  [REDACTED]  to correct such
            Event of  Default to the  satisfaction  of the  Developer  PROVIDED,
            HOWEVER,  that,  if such  Event of  Default  cannot be cured in such
            [REDACTED]  period through the diligent  efforts of Contractor,  but
            can be cured in a longer period without there  occurring any failure
            to  meet  the  Milestone  Schedule,  the  Contractor  shall  have an
            additional  period,  not to exceed  [REDACTED],  so long as it shall
            commence  the cure  during  such  [REDACTED]  period and  diligently
            pursue such cure. If the Contractor  fails to correct any such Event
            of  Default  to  the  satisfaction  of  the  Developer  within  such
            [REDACTED]  (or subject to the  conditions set forth in the previous
            sentence,  such longer period), or, upon the occurrence of any other
            Event of Default,  then the  Developer  on behalf of the Owners may,
            upon  written  Notice (a "NOTICE OF  EXERCISE OF  REMEDIES")  to the
            Contractor,  exercise  any  or  all  of  the  following  rights  and
            remedies:

                  (A)   exercise their rights under the Contractor Security;

                  (B)   exercise their rights with respect to the withholding of
                        payments to the  Contractor in  accordance  with Section
                        12.5 hereof;

                  (C)   take the Work wholly or partly out of the control of the
                        Contractor  or any  other  Person  in whose  control  or
                        possession  the Work or any part of it may be, and cause
                        to be completed the same in  accordance  with Section 25
                        hereof (a "TAKE OVER");

                  (D)   terminate  this Contract in  accordance  with Section 26
                        hereof (such event,  a "TERMINATION  FOR DEFAULT";  such
                        Notice of Exercise of Remedies, a "NOTICE OF TERMINATION
                        FOR DEFAULT"); or

                  (E)   exercise any and all rights and  remedies  they may have
                        under  law  or  equity,   including   seeking   specific
                        performance and the recovery of damages, subject, in any
                        event, to the provisions of Section 28 hereof.


                                       41

            The foregoing  remedies are cumulative,  and the Developer on behalf
            of the Owners may elect one or more thereof without prejudice to any
            other  right or remedy  the Owners may have,  subject,  however,  to
            Section 28 hereof. Notwithstanding any of the foregoing,  Contractor
            shall be  entitled  upon a  Termination  for  Default to be paid its
            Reimbursable  Costs (and any applicable  Fixed Fee and Incentive Fee
            so long as the Contractor has met the criteria for such fee pursuant
            to Section 12.2 hereof) for Work  performed in accordance  with this
            Contract and the  Contract  Documents  by the  Contractor  up to the
            effective  date of such  termination,  less any amount  owing to the
            Owners hereunder,  the latter of which amounts may be applied by the
            Owners to the payment and performance of any outstanding obligations
            of the Contractor hereunder.

24.2. NO PREJUDICE. No action taken by the Developer under this Section 24 shall
      prejudice any right of the Owners under Section 13 hereof.

24.3. NOTICE OF EXERCISE OF REMEDIES.  Any Notice of Exercise of Remedies  shall
      be conclusive  evidence of the matters  stated  therein for the purpose of
      allowing the Developer on behalf of the Owners to implement the provisions
      of this Section 24.

24.4. CONTRACTOR'S RIGHT TO SUSPEND WORK AND TERMINATE CONTRACT.

      (a)   SUSPENSION OF WORK BY THE CONTRACTOR.  [REDACTED]

      (b)   TERMINATION BY THE CONTRACTOR.  [REDACTED]

                                       42
<PAGE>

      (c)   EFFECT OF CONTRACTOR  TERMINATION.  Any termination of this Contract
            by the Contractor on account of any of the circumstances  referenced
            in the foregoing  Section 24.4(b) hereof shall be treated  hereunder
            as a  Termination  for  Convenience  for  purposes  of  the  Owners'
            obligation  to make payment to the  Contractor in the amounts and in
            the manner specified in Section 24.3 hereof.

               SECTION 25. TAKE OVER AND PAYMENTS TO THE DEVELOPER

25.1. REPLACEMENT CONTRACTORS. If the Developer on behalf of the Owners elects a
      Take Over,  the Owners may contract  with and employ any Person or Persons
      (each, a  "REPLACEMENT  CONTRACTOR")  to further  execute and complete the
      Work or any portion thereof,  and each Replacement  Contractor may provide
      such supplies and labor as may be necessary to enable that completion.

25.2. NO RIGHT OF  COMPENSATION.  In the  event of a Take Over  (whether  or not
      through a Replacement  Contractor),  the Contractor shall have no right to
      any  compensation  arising  from such  action  and the Owners may pay each
      Replacement Contractor such amounts of money as may be agreed upon between
      such Replacement Contractor and the Owners.

25.3. PAYMENTS TO THE OWNERS.  If the Developer on behalf of the Owners elects a
      Take Over, the Contractor shall,  without prejudice to any other rights or
      remedies of the Owners  hereunder or under  applicable Law with respect to


                                       43
<PAGE>

      the Event of Default (including recourse to the Contractor  Security),  be
      liable to the Owners (subject,  in any event, to the provisions of Section
      28 hereof) as direct damages for an amount equal to:

      (a)   all costs  (including  the costs of redoing  any portion of the Work
            not  reasonably  usable in the  completion of each Outside Plant) so
            incurred by the Owners; MINUS

      (b)   the total amount paid to the Owners under the Contractor Security.

      The  Contractor  shall  refund  to the  Owners  all  amounts  paid  to the
      Contractor  for Work  not  reasonably  usable  in the  completion  of each
      Outside Plant within  [REDACTED]  after written  Notice that such Work has
      been rejected by the Developer.

                       SECTION 26. TERMINATION FOR DEFAULT

26.1. EFFECT OF  TERMINATION.  A Termination  for Default shall not nullify this
      Contract but shall operate to terminate the Contractor's  right to proceed
      with the Work and to  discharge  the Owners from their  obligations  under
      this Contract.  A Termination for Default shall not relieve the Contractor
      from  liability  under  applicable  Law for  damages  for any  failure  or
      omission to perform any portion of this Contract prior to such termination
      or prejudice any legal rights of the Owners or  Contractor,  whether those
      rights arise under this Contract or otherwise,  subject,  in any event, to
      the provisions of Section 28 hereof.

26.2. TERMINATION  DATE. A Termination for Default shall be effective,  and this
      Contract shall be terminated,  when the Notice of Termination  for Default
      is served upon the Contractor.

26.3. RIGHT TO  TERMINATE.  The  Developer  on behalf of the Owners may exercise
      their  right to  terminate  this  Contract  whether or not any of the Work
      remains to be executed or whether or not the time limit for  completion of
      the Work has expired.

26.4. RIGHT TO COMPLETE THE WORK. On a Termination for Default, the Owners shall
      be empowered to complete the Work in the same manner as provided for under
      Section 25 hereof, as if the Work had been taken wholly out of the control
      of the Contractor by the Owners and this Contract had not been terminated.

                       SECTION 27. DUTIES UPON TERMINATION

27.1. GENERALLY.  Upon receipt of a Notice of Termination  for  Convenience or a
      Notice of  Termination  for  Default  (each,  a "NOTICE OF  TERMINATION"),

      (c)   unless otherwise  directed by the Developer,  use reasonable efforts
            to terminate all orders and contracts and  Subcontracts  (other than
            Subcontracts conditionally assigned to the Owners in accordance with
            Section  33.5  hereof)  to  the  extent  that  they  relate  to  the
            performance of Work terminated by the Notice of Termination;

      (d)   assign  to  the  Owners  (or  at  the  Developer's  direction,   any

            extent  directed by the Developer,  all of the  Contractor's  right,

                  connection with, the performance of the Work terminated by the
                  Notice of Termination; and

            (ii)  the  completed  or  partially   completed   plans,   drawings,
                  information, Permits and other property or items that, if this
                  Contract had not been terminated,  would have been required to
                  be furnished to the Owners;

      (g)   in the case of any property or items referred to in Section  27.1(f)
            hereof:

            (i)   use its best  efforts  in the case of an Event of  Default  or
                  reasonable   efforts  in  the  case  of  a   Termination   for

                  of other projects that the Contractor has, or will have, under
                  contract  for  other   customers;   the  amount   received  by
                  Contractor  therefor  shall be deducted  from the  Termination
                  Payment  (Convenience)  or paid in such  other  manner  as the
                  Developer on behalf of the Owners may direct; and

            (ii)  use reasonable  efforts to sell, in the manner,  at the times,
                  to  the  extent  and  at  the  price  or  prices  directed  or

            direct,  for the protection and preservation of the property related
            to this Contract that is in the Contractor's possession and in which
            the Owners have or may acquire an interest;


                                       45
<PAGE>

      (j)   grant  to  the  Owners,   any   Replacement   Contractor   and  each
            Subcontractor  a  continuing  right to use any and all  patented  or

            complete  each  Outside  Plant,  subject to  reasonable  proprietary
            restrictions; and

      (k)   at the Developer's request and at the Contractor's expense:

            (iv)  remove all such equipment,  waste and rubbish as the Developer
                  may designate.

27.2. SUBCONTRACTOR   CLAIMS.   For  a  Notice  of   Termination   for  Default,
      notwithstanding  Section  27.1(e),  the Owners  shall not be liable to the

      determination  of the rights and  obligations  of the  Parties  under this
      Contract.

                       SECTION 28. LIMITATION OF LIABILITY

28.1. NO CONSEQUENTIAL  DAMAGES.  Except as otherwise specified herein,  neither
      Party  (which  shall  include,  for  purposes  of  this  Section  28,  all
      Subcontractors and Vendors) shall be liable,  whether by contract, at law,
      in tort or otherwise, for any indirect or consequential losses or any loss
      of  income  or  profit,  loss of  opportunity  to do  business,  claims of
      customers  or the costs of, or  associated  with,  the use of  restoration
      facilities  or like items of indirect  or  consequential  damage.  Neither
      Party  shall make claims to the other for such  indirect or  consequential
      loss and each Party  hereby  releases,  subject to the other terms of this
      Contract,  the  other  from any  such  losses  and  shall  take all  steps
      necessary to extend like releases to such other Party's  Subcontractors or
      Vendors, as applicable.

<PAGE>

28.2. OTHER LIMITATIONS.  The total aggregate liability of the Contractor to all
      Owner Persons under, arising out of or in connection with this Contract or
      otherwise  with respect to the Work shall not exceed an  aggregate  amount
      (the "TOTAL LIABILITY CAP") equal to [REDACTED] of the Reimbursable Costs.
      Notwithstanding any of the foregoing,  the following shall not be included
      in, or subject to, the Total  Liability  Cap,  and shall not be taken into
      account  in  establishing  the  Contractor's  total  aggregate   liability
      hereunder:

      (a)   Indemnifiable Losses, for which there shall be no limit; and

      (b)   the Contractor's unconditional obligations to achieve RFS Acceptance
            of each Outside Plant.

28.3. SCOPE OF  LIMITATIONS.  With respect to matters  falling  within the Total
      Liability  Cap, the waivers and  disclaimers  of liability,  releases from
      liability,  limitations  and  apportionments  of liability  and  exclusive
      remedy provisions expressed in this Contract shall apply even in the event
      of the fault,  negligence (in whole or in part), strict liability,  breach
      of  contract,  or otherwise  of the Party  released or whose  liability is
      waived, disclaimed, limited, apportioned or fixed by such exclusive remedy
      provision, and shall extend to such Party's related or Affiliated entities
      and its and their directors, officers, employees and agents.

28.4. WORK  PROVIDED  BY OTHERS.  The  Contractor  shall have no  liability  for
      services,  materials  or  equipment  furnished  by Vendors.  To the extent
      practicable, the Owners shall procure that all indemnity, all releases and
      all  hold-harmless  agreements  contained in such Owner's  contracts  with
      third  parties  engaged to perform  services or supply  materials  for the
      System,  whereby such  parties  agree to  indemnify,  release and hold the
      Owner harmless shall extend like protection to the Contractor.

28.5. LOSS,  INJURY OR DAMAGE TO PERSONS,  THE SYSTEM OR THE WORK. Except to the
      extent constituting  Indemnifiable Losses hereunder,  (i) the Contractor's
      liability for Loss of or damage to any elements of the System or the Work,
      or for any injury to, or death or disease of, any Person, shall be limited
      to  those  payments  made  on the  Contractor's  behalf  by  the  insurers
      affording  the  insurance  described  in Section  41 hereof,  and (ii) the
      Owners shall release the  Contractor  from any Loss,  damage or expense in
      excess  of  those  payments  as a  result  of Loss of or  damage  to other
      property  of the Owners or in the custody of the Owners (or as a result of
      any injury to, or death or disease of, any Person).

28.6. TRANSFER OF OWNERSHIP.  The Owners agree that any future  recipient of any
      interest  in the  Systems  or the  Outside  Plant  will be  bound  by such
      releases  and  limitations  of  liability  such that the  total  aggregate
      liability of the Contractor to such Persons shall not exceed the limits of
      liability set forth herein.

28.7. HAZARDOUS   WASTE  OR  MATERIALS.   Except  to  the  extent   constituting
      Indemnifiable Losses hereunder, the Contractor shall have no liability for
      or in respect of hazardous  waste or materials  that may be encountered in
      carrying  out the Work,  and the Owners  shall  indemnify  the  Contractor
      against any additional costs and any liabilities to third parties that the
      Contractor  may incur as a  consequence  of such waste or materials  being
      encountered.

                   SECTION 29. THE CONTRACTOR'S ON-SITE DUTIES

29.1. REASONABLE PRECAUTIONS.  The Contractor acknowledges that, until such time
      as title to each  Outside  Plant has passed in its entirety to the Owners,
      it shall remain solely  responsible for the institution and maintenance of
      all such usual and reasonable precautions for the protection of the Sites,
      the Outside Plant and any Work, and for the prevention of danger or damage
      to all  persons or  property on or near the Sites.  Without  limiting  the
      generality of the foregoing,  the Contractor  shall,  as part of the Work,
      ensure that each Site is constructed,  secured, illuminated and maintained
      in such manner as would a reasonably prudent owner of a facility analogous
      to such Site.

29.2. WASTE  DISPOSAL.  The  Contractor  shall,  as part of its Work  hereunder,
      manage  and  dispose  of all waste  materials  in strict  accordance  with
      applicable Codes and Standards,  and shall, as part of its Work hereunder,
      keep each Site free from debris and waste  resulting from the  performance
      of the Work and the presence of the  Contractor  Persons at such Site.  In
      the event that any  Contractor  Person shall  discover the presence of, or
      cause the discharge of, any material of a hazardous  nature on or from any
      Site, the Contractor  shall  immediately  notify the Developer,  and shall
      instruct all Contractor  Persons to desist immediately from the Work until
      further instruction from the Developer.

                          SECTION 30. PERFORMANCE TESTS

30.1. GENERALLY.

      (a)   THE  CONTRACTOR'S  OBLIGATION  TO  CONDUCT  PERFORMANCE  TESTS.  The
            Contractor  shall  conduct and repeat as necessary  the  Performance
            Tests as required  hereunder in connection with RFS Acceptance (and,
            as  applicable,  Commercial  Acceptance)  and Final  Acceptance,  in
            accordance with the Performance Test Standards and such supplemental
            testing procedures, consistent with such Performance Test Standards,
            prepared  by the  Contractor  in  accordance  with  normal  industry
            standards.    The   Contractor    shall   permit   the   Developer's
            representatives  to be  present  during the  conduct of  Performance
            Tests and shall  provide to the  Developer  reports  and result data
            based upon the conduct of such Performance Tests.

      (b)   SAFETY.  If during  any  Performance  Test,  it is  discovered  that
            testing  cannot be  conducted  in a safe manner in  accordance  with
            industry practice, such Performance Test shall be terminated and the
            Contractor  shall  remedy  the  unsafe  condition,   whereupon  such
            Performance Test shall start over.

30.2. RIGHT OF WAIVER.  The  Developer  may,  but shall have no  obligation  to,
      waive, defer or reduce any of the requirements relating to the achievement
      of RFS Acceptance or Final Acceptance at any time by written Notice to the
      Contractor; PROVIDED that the Developer's exercise of any rights hereunder


                                       48
<PAGE>

      shall apply only to such  requirements  as the  Developer  may specify and
      shall in no event relieve the Contractor of any requirements, liability or
      other obligations not so specified.

30.3. LONG-TERM   OBLIGATIONS.   Nothing  in  this  Section  30,  including  the
      Developer's  approvals,  nor the issuance of a  Certificate  of Commercial
      Acceptance or a Certificate of RFS Acceptance,  shall in any way modify or
      alter the Contractor's  obligations with respect to Warranties  hereunder.
      Neither the inspection,  approval or payment, including the Final Payment,
      under this Contract shall:

      (a)   be construed to be an acceptance of any Defective Work;

      (b)   be an admission of the Contractor's  satisfactory performance of the
            Work; or

      (c)   relieve  the  Contractor  of  any  of  its  obligations  under  this
            Contract.

30.4. OPERATING REVENUES. Any and all revenues generated by the operation of the
      Outside Plants shall be solely for the account of the Owners.

                          SECTION 31. PLANT ACCEPTANCE

31.1. INITIAL  PLANT  COMMISSIONING  REPORT.  At  such  time  as the  Contractor
      determines  that it has  met the  requirements  for a  Certificate  of RFS
      Acceptance  in respect of either  Outside Plant (or segment  thereof),  it
      shall  submit to the  Developer  under cover of a Notice an initial  plant
      commissioning  report  (an  "INITIAL  PLANT  COMMISSIONING  Report")  with
      respect to such Outside Plant (or segment thereof)  prepared in accordance
      with the Testing and Acceptance  Specifications referenced in Table 2-C to
      the Network  Description and Project Scope.  Within thirty (30) Days after
      its  receipt of the  relevant  Initial  Plant  Commissioning  Report,  the
      Developer shall:

      (a)   issue a Certificate  of RFS  Acceptance  in accordance  with Section
            31.2 hereof; or

      (b)   not accept the relevant  Outside  Plant (or segment  thereof) in its
            existing  condition  and the terms and  provisions  of Section  31.5
            hereof shall apply.

31.2. RFS ACCEPTANCE.

      (a)   GENERALLY.  The  Contractor  shall,  together with its submission of
            Initial  Plant  Commissioning  Report to the Developer in connection
            with its  application for RFS Acceptance of either Outside Plant (or
            segment thereof),  certify to the Developer that, as of the date set
            forth in such certification:

            (i)   such Outside Plant (or segment thereof) (A) has been completed
                  in accordance  with the Technical  Requirements  and any other
                  requirements of this Contract (except for Punch List Items, if
                  any), and (B) has passed, as of such  certification  date, all
                  Performance  Tests as required by the Technical  Requirements;
                  and


                                       49
<PAGE>

            (ii)  all  requirements  of this  Contract  (except  for Punch  List
                  Items,  if any)  relating  to such  Outside  Plant or  segment
                  thereof  (including  all  Technical  Requirements)  have  been
                  fulfilled and all required  documentation  has been completed,
                  in each case  other than  those  that do not,  by the  express
                  terms hereof, have to be fulfilled or completed on or prior to
                  the RFS  Date;  PROVIDED,  that RFS  Acceptance  shall  not be
                  deemed to  include or require  (A)  completion  of work by the
                  Vendors  or  other  of  the  Owners'   agents  or  contractors
                  hereunder,  except  to  the  extent  necessary  to  allow  the
                  Contractor to test each Outside  Plant in accordance  with the
                  Performance  Test  Standards  (and to the extent that any such
                  necessity  results  in any  delay  or  increased  cost  to the
                  Contractor  in achieving RFS  Acceptance,  such event shall be
                  deemed  a  Owner-Caused  Delay,  and the  Contractor  shall be
                  entitled  to  equitable  relief  to the  extent  specified  in
                  Section 15.1 hereof) or (B) the absence of minor  defects that
                  do not  materially  affect the use or operation of the Outside
                  Plant and are included on a Punch List adopted by the Parties.

            The Developer shall review the  Contractor's  submission  within the
            period  specified in Section 31.1 hereof and, to the extent that the
            Developer has neither requested additional  information nor raised a
            Dispute  with  respect  to the  Contractor's  submission  by written
            Notice to the Contractor  (which Notice shall articulate the reasons
            for   the   Developer's    determination   that   the   Contractor's
            certifications  made  in its  application  for  RFS  Acceptance  are
            erroneous or are inaccurately dated) prior to the expiration of such
            period,  shall issue a "CERTIFICATE OF RFS ACCEPTANCE" in accordance
            with the Technical  Requirements  dated,  and to be effective as of,
            the date (the "RFS DATE") as of which the  Contractor has certified,
            by its Notice  given  pursuant  to  Section  31.1  hereof,  that all
            conditions  for RFS  Acceptance  have been met. The following  shall
            occur on the RFS Date:

                  (A)   each Outside  Plant shall be deemed to be  provisionally
                        accepted by the Owners; and

                  (B)   title to any part of the relevant Outside Plant that has
                        not previously passed shall be transferred to the Owners
                        in  accordance  with  Section  36.7 hereof and the risks
                        thereof  and  responsibility  for  routine   maintenance
                        shall,  subject to Section 31.2(b)  hereof,  pass to the
                        Owners.

      (b)   PUNCH  LIST.  The   Certificate  of  RFS  Acceptance   may,  in  the
            Developer's sole  discretion,  be unqualified or may have annexed to
            it a Punch List,  which shall be compiled by the  Developer,  of any
            outstanding  minor  deficiencies  or  items to be  completed  by the
            Contractor.  The Contractor shall, as part of its Work hereunder and
            as soon as  practicable,  remedy the  deficiencies  and complete the
            Work  indicated  on all  such  listed  items  so as to  ensure  full
            compliance with the requirements of this Contract.


                                       50

31.3. COMMERCIAL ACCEPTANCE. If at any time the Developer determines that, based
      upon  information  supplied by the Contractor,  any portion of the Outside
      Plant is suitable to be put into  commercial  service (such  portion,  the
      "RFCS PORTION"),  then the Developer, at its option and without obligation
      (except to the extent specified in clause (a) of this Section 31.3), shall
      issue,  with the  consent  (except as  provided in such clause (a)) of the
      Contractor (which consent shall not be unreasonably  withheld or delayed),
      to the Contractor a "CERTIFICATE OF COMMERCIAL ACCEPTANCE."

      (a)   RFCS SEGMENTS.  If, based upon ODF-to-ODF  Performance  Test results
            (as well as any  other  information  and  testing  data  that  would
            otherwise  be  required to  demonstrate  RFS  Acceptance  for either
            Outside Plant on an overall basis) provided to it by the Contractor,
            the  Developer  determines  that any RFCS Segment meets the criteria
            for RFS  Acceptance  as set  forth in  Section  32.1  hereof  and is
            suitable to be put into commercial service, then the Developer shall
            issue to the  Contractor,  within fifteen (15) Days after  receiving
            from the Contractor all testing data and other information necessary
            to make the foregoing  determination,  a  Certificate  of Commercial
            Acceptance  in respect of the relevant  RFCS  Segment.  In the event
            that the  Developer is unable to issue a  Certificate  of Commercial
            Acceptance  for any RFCS  Segment,  it shall  notify the  Contractor
            promptly  (but,  in any event,  within the  foregoing  15-Day period
            after the  Contractor's  submission  of the  relevant  data)  with a
            written Notice  specifying in reasonable  detail the reasons for its
            inability to do so.

      (b)   EFFECT OF COMMERCIAL ACCEPTANCE. Upon the Commercial Acceptance Date
            with respect to any RFCS Portion:

            (i)   the Owners  shall be entitled to commence  commercial  service
                  over such RFCS Portion;

            (ii)  title to the RFCS Portion that has not previously passed shall
                  be transferred  to the Owners in accordance  with Section 36.7
                  hereof,  and  the   responsibility  for  routine   maintenance
                  thereof, pass to the Owners;

            (iii) the risk for the RFCS  Portion  shall be vested in the Owners,
                  except that any risk attributable to the Outside Plant or part
                  of the Outside  Plant that requires  corrective  action by the
                  Contractor  shall  remain  the  sole   responsibility  of  the
                  Contractor;

            (iv)  the requirements of RFS Acceptance for such RFCS Portion shall
                  be  deemed  to have  been met as of the  date of the  relevant
                  Certificate of Commercial  Acceptance and, for purposes of the
                  Developer's  assessment of RFS Acceptance for overall  Outside
                  Plant of which such RFCS Portion is a part,  such RFCS Portion
                  shall  require no further  testing or inspection in connection
                  with that RFS Acceptance process; and

            (v)   the  Warranty  Period  shall  commence in respect of such RFCS
                  Portion.


                                       51
<PAGE>

      (c)   PUNCH LIST. The Certificate of Commercial  Acceptance  shall have as
            an attachment a list of items requiring  corrective action and items
            still to be provided. Such corrective action shall be taken promptly
            and  such  items  completed  by the  Contractor  as part of its Work
            hereunder. When:

            (i)   the outstanding corrective action has been taken;

            (ii)  all outstanding items have been delivered and approved; and

            (iii) the  conditions  described  in Section  31.2  hereof have been
                  satisfied,   the  Developer   shall  issue  a  Certificate  of
                  Commercial  Acceptance.  Upon  such  issuance,  title  to  the
                  remainder  of the Outside  Plant shall be  transferred  to the
                  Owners in  accordance  with  Section  36.7 hereof and the risk
                  with respect to such remainder of the Outside Plant shall pass
                  to the Owners and the  provisions  of  Section  31.2(b)  shall
                  apply.

      (d)   NO DIMINISHMENT OF THE CONTRACTOR'S  OBLIGATIONS.  The issuance of a
            Certificate  of  Commercial  Acceptance  shall in no way relieve the
            Contractor from its obligation to provide  Outside Plants  complying
            with the technical and other  requirements  of this Contract and, in
            particular,  any  deterioration  or Defects in either  Outside Plant
            occurring  or  becoming  known  between the date of issuance of such
            Certificate  and  the  date  of  issuance  of a  Certificate  of RFS
            Acceptance shall be corrected at the sole expense of the Contractor,
            except to the  extent  that such  Defects  are  attributable  to the
            operation or maintenance (or lack thereof) of the RFCS Portion under
            the control of the Owners.

      (e)   EQUITABLE RELIEF FOR  INTERFERENCE  WITH WORK. In the event that the
            Owners' commencement of commercial  operations on or with respect to
            any RFCS Portion(s)  obstructs,  delays or otherwise interferes with
            the Contractor's prosecution of the Work, such obstruction, delay or
            interference shall be treated as an "Owner-Caused Delay" pursuant to
            Section  16.1(e)  hereof,  entitling the  Contractor to  appropriate
            adjustment to the Milestone Schedule or the Target Cost,  determined
            in accordance with Section 15.1 hereof.

31.4. DOCUMENTATION   TO  BE  DELIVERED   UPON  RFS   ACCEPTANCE  OR  COMMERCIAL
      ACCEPTANCE.  Within forty-five (45) Days after achieving each RFS Date and
      any Commercial Acceptance Date, as applicable, the Contractor shall submit
      to the Developer the following  documents,  in each case,  relating to the
      particular  Outside Plant or RFCS Portion having  achieved,  respectively,
      RFS Acceptance or Commercial Acceptance:

      (a)   one (1) hard  copy  and one (1)  electronic  copy of the "as  built"
            drawings for such Outside Plant or RFCS Portion; and

      (b)   test documentation, the operating manuals and serial numbers for the
            equipment associated with such Outside Plant or RFCS Portion.

31.5. FAILURE TO ACHIEVE RFS ACCEPTANCE OR COMMERCIAL  ACCEPTANCE.  If neither a
      Certificate of RFS  Acceptance nor a Certificate of Commercial  Acceptance


                                       52
<PAGE>

      is issued due to the  existence of Defects with respect to either  Outside
      Plant or the Work, the Developer  shall,  without  prejudice to any of its
      other rights and remedies under this Contract, issue a list detailing such
      Defects  and  advise  the  Contractor  of a period  of time in which  such
      Defects  shall be  remedied  to the  satisfaction  of the  Developer.  The
      Contractor shall issue an additional  commissioning report similar in form
      and substance to the Initial Plant  Commissioning  Report to the Developer
      after all actions  required to remedy such  Defects have been taken by the
      Contractor  and such report shall be  considered  in  accordance  with the
      provisions of Section 31.1 hereof.

31.6. FINAL   ACCEPTANCE.   The  Developer  shall  issue  to  the  Contractor  a
      "CERTIFICATE OF FINAL  ACCEPTANCE" in respect of each Outside Plant within
      ten (10)  Days  after the date on which  all of the  following  conditions
      have, in the Developer's judgment, been satisfied in full:

      (a)   the Developer has issued a Certificate of RFS Acceptance;

      (b)   the  Warranty  Period  applicable  to each  component of the Outside
            Plant has expired and there are no Warranty claims  outstanding with
            respect thereto;

      (c)   any and all items on all Punch Lists  relating to the Outside  Plant
            have been completed; and

      (d)   the  Developer  has  received the  Certificate  of Payment and Final
            Release.

                             SECTION 32. WARRANTIES

32.1. GENERAL   WARRANTIES.   Notwithstanding  any  Outside  Plant  having  been
      provisionally  accepted by the Owners and without  prejudice  to any other
      warranty made by the Contractor  hereunder,  the Contractor warrants until
      the expiration of the Warranty Period to the Owners that the Work and each
      Outside Plant shall (each of the following, a "GENERAL WARRANTY"):

      (a)   be free from  Defects in design  (to the extent of the  Contractor's
            responsibility  therefor,  as limited as  described  in Section  4.2
            hereof), materials, construction and workmanship;

      (b)   comply  with  all  applicable  requirements  of Laws and  Codes  and
            Standards;

      (c)   be  fit  for  the   particular   use   described  in  the  Technical
            Requirements; and

      (d)   meet the Network  Description  and Project  Scope,  the  Performance
            Parameters and all other requirements of this Contract.

32.2. NOTIFICATION OF BREACH OF WARRANTY. If any aspect of the Work has not been
      performed in accordance with any General  Warranty,  the Contractor shall,
      at its own expense, either repair (in accordance with Section 32.3 hereof)
      or replace (in accordance with Section 32.4) all such Work; PROVIDED that:


                                       53
<PAGE>

      (a)   the  Developer  has provided the  Contractor  with a written  Notice
            stating with reasonable specificity the basis for Developer's belief
            that the relevant Work has not been performed to the requirements of
            the applicable General Warranty; and

      (b)   such  Notice  has been  given  within a  reasonable  time  after any
            Owner's discovery of the facts or circumstances  giving rise to such
            Owner's  belief  and,  except to the extent  relating  to any latent
            Defect not  reasonably  discoverable  by the Owners  within the time
            period available,  is issued prior to the expiration of the Warranty
            Period.

32.3. REPAIR  GENERALLY.  If at any time within the  Warranty  Period any Defect
      occurs in  either  Outside  Plant as a result  of a  failure  of a General
      Warranty, the Contractor shall, upon receiving appropriate Notice given in
      accordance with Section 32.2 hereof,  promptly repair or replace such part
      or parts  thereof to the  satisfaction  of the  Developer on behalf of the
      Owners without any charge to the Owners.  The Contractor  shall make every
      reasonable effort to minimize the period of time that any Outside Plant is
      out of service for repair and testing. For failures or any situations that
      cause  or risk an  outage  of any  Outside  Plant,  the  Contractor  shall
      initiate a corrective  intervention  immediately  after  receipt of Notice
      from the Developer.

32.4. REPAIR OR REPLACEMENT. During the Warranty Period:

      (a)   the Contractor shall make an appropriate investigation,  at its sole
            cost  and  expense,  of any  items of  Defective  Work  repaired  or
            replaced pursuant to this Section 32 to determine, to the reasonable
            satisfaction  of the Developer,  the type of Defect and the cause of
            failure of the defective item or items. The Contractor shall provide
            a descriptive  written report to the Developer on the results of the
            investigation,  the type of Defect found and, when appropriate,  the
            repair carried out on such  defective item or items.  The Contractor
            shall also state  whether the type of Defect and the "root cause" of
            the failure  are the result of a generic  Defect  occasioned  by not
            adhering to the Technical  Requirements  and whether such failure is
            expected to occur elsewhere in the Outside Plant;  PROVIDED that the
            Contractor's  determination shall not be conclusive for the purposes
            of  this  Section  32.  Additionally,  whether  or not  having  been
            occasioned by a Defect,  the Contractor may independently  undertake
            such  investigations to determine whether a generic Defect may exist
            and, if any generic Defect is identified,  the Contractor  shall, in
            coordination with the Developer  appropriately repair or replace all
            affected elements of the Outside Plant; or

      (b)   the Developer may alternatively  direct the Contractor to conduct an
            investigation  of suspected  generic  Defects wherein the Contractor
            shall  prepare  a  descriptive  written  report as  provided  for in
            Section  32.4(a).  If,  as  the  result  of any  such  investigation
            conducted pursuant to this Section 32.4(b),  all Work is found to be
            free  of  any  Defects  for  which  the  Contractor  is  responsible
            hereunder,  the Developer shall, on behalf of each Owner,  reimburse
            the  Contractor  for  all  costs  incurred  in the  conduct  of such
            inspection  and  evaluation,   which  reimbursement  shall  include,
            exclusively  for purposes of this Section 32.4,  compensation to the


                                       54

            Contractor  for  Contractor  Persons  engaged and its  equipment and
            facilities  utilized in such connection at each of their  respective
            rates customarily charged in similar projects.

32.5. REPAIR BY THE DEVELOPER. If upon the occurrence of any breach of a General
      Warranty  during the  Warranty  Period the  Contractor  has failed,  after
      proper  Notice  given by the  Developer  in  accordance  with Section 32.2
      hereof, to (i) make prompt repair or replacement, or (ii) minimize Outside
      Plant  out-of-service  time for  testing  and repair,  the  Developer  may
      arrange  for the  repair  or  replacement  of any  Defective  Work and the
      Contractor  shall  reimburse  the  Developer  for the cost of  repairs  or
      replacements; PROVIDED, the Developer satisfies its commitment to (i) give
      the  Contractor  prompt  Notice  of  any  such  repair  undertaking,  (ii)
      coordinate its repair  activities with those of the Contractor,  and (iii)
      comply with the Contractor's  repair policies  delivered to the Developer,
      and the Contractor shall be permitted to have a representative  present to
      observe such  repairs.  Any repair by the  Developer  shall not in any way
      diminish the Contractor's obligations under this Section 32.

32.6. REPAIRED OR  REPLACEMENT  PARTS.  Each defective part repaired or replaced
      pursuant to this Section 32 (a "REPLACEMENT ITEM") shall itself be subject
      to the provisions of this Section, and shall be warranted from the date of
      repair  or  replacement,  as  applicable,  until  a  date  two  (2)  years
      thereafter;   PROVIDED  that  the  Warranty   Period   applicable  to  any
      Replacement Item shall in no case exceed thirty-three (33) months from the
      applicable RFS Date.

32.7. THE DEVELOPER'S  EXPENSES.  The Contractor  shall pay to the Developer all
      the  expenses (if any)  incurred by the  Developer in testing or examining
      any part of each Outside  Plant for the purpose of or in  connection  with
      this  Section  32 or in or about  or in  connection  with the  correction,
      replacement  or repair of any part of such Outside Plant  attributable  to
      the Contractor's breach of its General Warranty obligations.

32.8. SCOPE OF LIABILITY FOR DEFECTS. Except to the extent that the Developer or
      any Owner may have a remedy  pursuant to Section 39 hereof,  the  remedies
      specified in this Section 32 are the  Developer's and the Owners' sole and
      exclusive  remedies for Defects  arising out of or in connection  with the
      Contractor's  performance  under this Contract.  There are no standards of
      performance,  guarantees or warranties  with respect to Defects other than
      those expressed in this Section 32.

                    SECTION 33. ASSIGNMENT AND SUBCONTRACTING

33.1. GENERALLY.  The Contractor shall not, without the prior written consent of
      the  Developer,  assign this  Contract or any part of the Work, or assign,
      mortgage,  charge or encumber  any of the moneys due or becoming due under
      this Contract,  or any other benefit or obligation  whatsoever arising, or
      that may arise under this Contract.  The Contractor  shall not be relieved
      of  responsibility  under this  Contract for such parts of the Work as are
      assigned or as may be  subcontracted.  To the extent  that the  Contractor
      subcontracts portions of the Work to any of its Affiliates, the Contractor
      guarantees  and  shall  ensure  such   Affiliate's   compliance  with  all


                                       55
<PAGE>

      requirements  of  this  Contract  and  the  Contract  Documents,  and  the
      Developer  and the Owners  agree to hold only the  Contractor  and, to the
      extent provided for in the Corporate Guarantee, Bechtel Corporation liable
      for any Affiliate's failure to so comply.

33.2. SUBCONTRACTS.  From and after the  execution  date of this  Contract,  the
      Contractor  shall not enter  into a  contract  with a  Subcontractor  that
      requires  payment in excess of DM 200,000 without the written  approval of
      the Developer. In addition,  Contractor shall ensure that each Subcontract
      shall contain:

      (a)   provisions  allowing the  Developers  and its  designees  reasonable
            access to all plants,  offices and Sites in accordance  with Section
            19 hereof;

      (b)   provisions  stating  that the  Subcontractor  shall  have no  rights
            against  the  Developer  or any Owner and shall not create or assert
            any Lien (equitable or otherwise) against the Developer,  any Owner,
            any Outside Plant or any of the Work;

      (c)   provisions  designating the Developers and the Owners as third-party
            beneficiaries  and setting  forth a  conditional  assignment of such
            Subcontract to such Persons in accordance  with Section 33.5 hereof;
            and

      (d)   such other  provisions of this Contract as prudently  should be made
            applicable to such  Subcontract or  Subcontractor in order to permit
            the  Contractor  to fulfill its  obligations  hereunder or otherwise
            give full effect to the provisions of this Contract.

33.3. EXISTING SUBCONTRACTS.  The Contractor represents,  warrants and covenants
      that all  Subcontracts  entered into by the  Contractor on or prior to the
      date hereof contain, or shall be amended to contain, provisions addressing
      the matters set forth in Section 33.2 hereof.

33.4. BREACH.  If the  Contractor  commits  any breach of this  Section  33, any
      assignment,  mortgage, charge, encumbrance or Subcontract in contravention
      of this Section 33 shall,  as against the Developer or any Owner,  be null
      and void and of no force and  effect,  and may be  ignored  by such  Owner
      Persons.  The  Contractor  shall  protect,   defend,  indemnify  and  keep
      indemnified  the Developer and the Owners  against all Losses  suffered or
      incurred by such  Persons  arising  out of or related to such  assignment,
      mortgage, charge, encumbrance or Subcontract.

33.5. CONDITIONAL ASSIGNMENT. The Contractor shall make a conditional assignment
      to the Developer for the benefit of the Owners of all of the  Contractor's
      Subcontracts  and all Permits entered into,  acquired or obtained,  as the
      case may be, in connection  with the  performance  of this Contract or any
      part of the Work.  Upon a  Termination  for  Default  or Take  Over,  such
      conditional assignment shall become fully effective and the Developer (and
      the Owners, as applicable) shall acquire all benefits of such Subcontracts
      and Permits (including prices and delivery dates,  discounts,  rebates and
      refunds)  except for those  Subcontracts  or Permits,  if any, that relate
      exclusively to the portion of the Work, if any, not Taken Over.


                                       56
<PAGE>

33.6. NO OBLIGATIONS OF OWNER PERSONS TO SUBCONTRACTORS. No Subcontractor or any
      of its employees,  representatives  or agents shall be deemed or construed
      to be employees,  representatives or agents of the Developer or any Owner.
      No Subcontractor shall be deemed a third-party beneficiary of, or have any
      interest in, this Contract.

                     SECTION 34. THE CONTRACTOR'S PERSONNEL

The Contractor shall employ,  and shall ensure that its  Subcontractors  employ,
for Work to be performed in connection  with this Contract only such persons who
are safety-conscious, suitably skilled and experienced, and the Contractor shall
agree to provide to the  Developer,  subject to the  Developer's  assumption  of
appropriate  confidentiality  undertakings in respect thereof,  such resumes and
other relevant biographical and employment data as of such date on file with the
Contractor  for all such persons as the Developer may  reasonably  request.  The
Developer,  or its designee,  may object to and direct the  Contractor to remove
any  person  employed  by the  Contractor  or any  Subcontractor  as to whom the
Developer may provide substantiation of a lack of safety-consciousness, suitable
skills or experience and such person shall be removed within a reasonable period
of time and shall not be employed  again for any portion of the Work without the
prior approval of the Developer's Representative.

                        SECTION 35. THE DEVELOPER'S STAFF

35.1. GENERALLY. Where the Technical Requirements provide for stipulated Work to
      be carried  out by the  Developer,  such Work shall be carried  out in the
      manner   and  with  the   responsibilities   as  defined   therein.   Such
      participation  by  any of the  Developer's  staff  (or  any  other  Person
      designated  by the  Developer by contract or  otherwise) in the Work shall
      not be construed as relieving the Contractor of its responsibility for the
      design, quality and performance of each Outside Plant.

35.2. LIMITATIONS.  Where any of the  Developer's  staff  (or any other  Persons
      designated by the Developer by contract or otherwise)  participate  in the
      Work, they shall remain officers,  partners, employees or agents and under
      the administrative  control of the Developer.  The Contractor shall not be
      liable  for any  negligent  act or  omission  of  such  staff,  agents  or
      designees,  but if in giving  instructions  to be carried  out by any such
      Persons, or by omitting to give such instructions, the Contractor fails to
      use proper  skill and care,  the  Contractor  shall be deemed to have been
      negligent and shall be liable for the consequence of such negligence.

                                SECTION 36. TITLE

36.1. GENERALLY.  The Contractor shall transfer title  ("EIGENTUM") to the Cable
      Links (and all  portions  thereof)  in  accordance  with the German Law of
      Property ("SACHENRECHT").  Such transfer of title shall be effected by the
      Contractor  in such  manner as to realize  that (i) Carrier 1 and MFN will
      each acquire separate title ("ALLEINEIGENTUM") to one identical Cable Link
      and   (ii)   Viatel   will   acquire    separate    title   to   (A)   one
      Contractor-completed  Cable Link  including  Fiber Optic Cable pulling and


                                       57
<PAGE>

      (B) one  Contractor-completed  Cable Link  without  such Fiber Optic Cable
      pulling.  Each of Carrier 1, MFN and Viatel (or any assignee thereof as to
      whom the  Contractor  has been  notified in  accordance  with  Section 2.3
      hereof)  is,  for  purposes  of its right to  receive  title to Work items
      hereunder, referred to in this Section 36 as a "DESIGNATED OWNER".

36.2. TITLE TO SUPPLIES AND WORK.  When held or installed by the  Contractor  at
      any Site,  all  physical  items  ("KORPERLICHE  GEGENSTANDE")  of  supply,
      equipment,  materials and other Work (each, an "ITEM") intended for use in
      each Cable Link shall be identified  by the  prominent  display of notices
      and by marking  the Items,  in  accordance  with the  Storage  and Marking
      Procedures  to be attached  hereto as APPENDIX 8, as being the property of
      each Designated Owner. The Contractor shall suitably annotate the relevant
      books of inventory and installation, and shall allow the Developer access,
      for and on behalf of the Designated Owners, to its premises and records in
      order to check that such identification has been carried out.

36.3. TRANSFER OF TITLE.  The Contractor  shall transfer title  ("EIGENTUM")  to
      each Item  intended  for use in each  Cable Link to the  Designated  Owner
      thereof  upon  submission  to  the  Developer  of the  Contractor  Invoice
      (together with all  documentation  required under Section 12.5 hereof) for
      the  Reimbursement  Invoice,  specifying that such Item is payable by such
      Designated Owner, subject, in any event, to any rights the Owners may have
      under  Section  12.5  hereof.  For  the  purpose  of this  title  transfer
      ("EIGENTUMSUBER-TRAGUNG"), the submission of the Contractor Invoice to the
      Developer for payment by the Developer on behalf of each Designated  Owner
      constitutes the offer,  and the payment thereof by the Developer on behalf
      of such Designated  Owner  constitutes  the  acceptance,  of the agreement
      among the Contractor and such Designated Owner that the title to all Items
      either  (i)   identified  in  such   Contractor   Invoice  and  supporting
      documentation or (ii) specified in this Contract or any Contract  Document
      as included in the Milestone  Event for which such  Contractor  Invoice is
      paid  or  payable  (the  "TRANSFERRED  PROPERTY"),   shall  pass  to  such
      Designated   Owner.  The  Contractor  shall  transfer  direct   possession
      ("UNMITTELBARER   BESITZ")  of  each  Item  of  Transferred  Property,  as
      identified in accordance with the Storage and Marking Procedures,  to each
      Designated Owner upon the agreement  referred to in the preceding sentence
      relating thereto;  PROVIDED, that if the Contractor is to retain, pursuant
      to any  provision of this  Contract or any Contract  Document,  possession
      ("BESITZ",  hereinafter  "POSSESSION") of any Item of Transferred Property
      (each, a "RETAINED  ITEM") until any later date, the provisions of Section
      36.5 hereof shall apply. The Contractor  represents and warrants that each
      Designated  Owner shall  acquire good and clear title to such  Transferred
      Property, free and clear of all Liens (other than Owner Liens).

36.4. REMOVAL OF LIENS.  The  Contractor  shall  secure the  removal of any Lien
      (other than Owner  Liens) on the Work or any portion of each Cable Link or
      Outside Plant within thirty (30) Days after obtaining  notice thereof.  If
      any Lien (other than Owner Liens) is not discharged, satisfied or released
      within such 30 Days or such  earlier time as may be necessary in order for
      any Owner to avoid being damaged  thereby,  the Developer may, upon Notice
      to the  Contractor of its intention to do so, apply any funds  withheld or
      moneys to become due to the Contractor hereunder to satisfy,  discharge or


                                       58
<PAGE>

      secure the release  (including by posting a bond) of such items.  Any such
      application  by the  Developer  shall be deemed  payment  on behalf of the
      Owners to the Contractor. Any additional expense incurred by the Developer
      (or any Owner) as a result of the Contractor's  breach of any provision of
      this Section 36.4 shall be borne by the Contractor.

36.5. NO RELEASE OF THE CONTRACTOR;  CONTRACTOR  OBLIGATIONS IN LIEU OF TRANSFER
      OF DIRECT  POSSESSION.  The transfer of title shall not absolve or release
      the Contractor from any other obligation or liability under this Contract.
      With respect to Retained Items,  the Contractor and each of the Designated
      Owners  hereby agree that, in lieu of delivering  direct  Possession,  the
      Contractor shall diligently  safeguard such Retained Items for each of the
      Designated  Owners  ("BESITZMITTLUNGSVERHALTNIS",  Secs.  868,  930 of the
      German  Civil Code  [BGB]).  To the extent  that  third  parties  (such as
      Subcontractors  or vendors) are in Possession of any Transferred  Property
      at the time of the  transfer of title  ("EIGENTUMSUBERTRAGUNG")  or obtain
      such  Possession  from the Contractor  thereafter,  the Contractor  hereby
      assigns to each Designated Owner any claim the Contractor may have for the
      retrieval or reconveyance  ("ABTRETUNG DES  HERAUSGABEANSPRUCHS")  of such
      Transferred Property.

36.6. BAILMENT.  The Contractor  shall serve as bailee of any Retained Items and
      shall remain  liable to each  Designated  Owner (acting by and through the
      Developer in the enforcement of such liability) and shall bear the risk of
      loss or damage thereto,  until the risk of loss thereof has passed to such
      Designated Owner in accordance with Section 40 hereof. Notwithstanding the
      foregoing,  it shall be the individual  responsibility  of the appropriate
      Designated  Owner to take all  action  within  its  reasonable  control to
      prevent any third party in  contravention  of the  Contractor's  aforesaid
      bailee rights to take direct  Possession of any of the Designated  Owner's
      Items  of  Transferred  Property  while  Work on such  property  is  still
      ongoing.

36.7. TITLE TO THE CABLE  LINKS.  To the extent  title has not  previously  been
      transferred to the appropriate  Designated  Owner pursuant to Section 36.3
      hereof  (other  than Work being  completed  pursuant  to  Section  27.1(h)
      hereof), then, upon:

      (a)   the issuance of a Certificate  of RFS Acceptance or a Certificate of
            Commercial Acceptance in accordance with Section 31 hereof; or

      (b)   termination, in whole or in part, of this Contract or the Contractor
            pursuant to Sections 23 or 26 hereof,

      Contractor shall be obligated to transfer absolute and exclusive right and
      title  to and  interest  in any and all  parts  of the  Cable  Links  (the
      "Remaining Parts"), as such parts shall be specifically  identified as the
      separate property reserved for each of the Designated Owners:

            (i)   in  the  relevant  "as  built"   drawings,   in  the  case  of
                  Certificate  of RFS  Acceptance or a Certificate of Commercial
                  Acceptance,  to be delivered to the Developer (for the benefit
                  of the Owners) within the time periods specified herein; or


                                       59
<PAGE>

            (ii)  in the case of any  termination  pursuant to Sections 23 or 26
                  hereof,   all  such  plans,   specifications  and  inventories
                  otherwise  required to be  prepared  for or  delivered  to the
                  Developer (for the benefit of the Owners)  pursuant to Section
                  27.1 hereof;

      to such  Designated  Owner upon the  Developer's  payment on behalf of the
      Owners of the Final Payment (or, as applicable,  any Termination Payment).
      To the extent that  Possession has not been  previously  transferred  from
      Contractor to the Designated Owners, Contractor shall also be obligated to
      transfer direct Possession  (UNMITTELBARER  BESITZ) to the Remaining Parts
      to  the  Designated  Owners.  For  this  purpose,  the  submission  of the
      Contractor's  invoice (with the relevant  supporting  information)  to the
      Developer  for  such  payments  from  the  Developer  on  behalf  of  each
      Designated  Owner shall  constitute the offer,  and the payment thereof by
      the  Developer on behalf of such  Designated  Owner shall  constitute  the
      acceptance,  of the agreement  among the  Contractor  and such  Designated
      Owner that the title to all remaining  Cable Link  portions  shall pass to
      such Designated  Owner.  The Contractor  represents and warrants that each
      Designated  Owner shall  acquire  good and clear title  thereto,  free and
      clear of all Liens (other than Owner Liens).

                   SECTION 37. REPRESENTATIONS AND WARRANTIES

37.1. CONTRACTOR'S   REPRESENTATIONS  AND  WARRANTIES.   The  Contractor  hereby
      represents and warrants that:

      (a)   ORGANIZATION; POWER AND AUTHORITY. It is a limited liability company
            duly  organized  and validly  existing  under the Laws of the United
            Kingdom,  and it or its relevant  Affiliates  are  authorized  to do
            business in all jurisdictions where the Work is to be performed, and
            it has all  requisite  legal  power and  authority  to execute  this
            Contract  and  to  perform  the  terms,  conditions  and  provisions
            thereof.

      (b)   AUTHORIZATION.  The execution and delivery by the Contractor of this
            Contract has been duly authorized by all requisite corporate action.

      (c)   ENFORCEABILITY.  This  Contract  constitutes  the  legal,  valid and
            binding obligation of the Contractor, enforceable in accordance with
            the  terms  thereof  except  as  enforceability  may be  limited  by
            applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
            other similar Laws affecting  creditors' rights generally and to the
            extent that the remedies of specific performance,  injunctive relief
            and  other  forms of  equitable  relief  are  subject  to  equitable
            defenses,  the  discretion of the court before which any  proceeding
            therefor may be brought, and the principles of equity in general.

      (d)   NO CONFLICT.  Neither the execution,  delivery or performance by the

<PAGE>

            (i)   a  violation  of, or a conflict  with,  any  provision  of the
                  organizational documents of the Contractor;

            (ii)  a contravention  or breach of, or a default under, any term or
                  provision of any material contract, agreement or instrument to
                  which the Contractor is a party or by which it or its property
                  may be bound, which contravention,  breach or default could be
                  reasonably  expected to have a material  adverse effect on the
                  ability of the  Contractor  to perform its  obligations  under
                  this Contract to consummate the  transactions  contemplated by
                  this Contract; or

            (iii) a violation by the Contractor of any Law.

      (e)   NO VIOLATION OF LAW. It is not in violation of any Law  promulgated,
            or  judgment   entered,   by  any  governmental   authority,   which
            violations, individually or in the aggregate, would adversely affect
            it or its performance of any obligations hereunder.

      (f)   LITIGATION.  There are no actions, suits or proceedings, now pending
            or (to its best knowledge) threatened against it before any court or
            administrative  body or  arbitral  tribunal  that  might  materially
            adversely affect the ability of the Contractor or any  Subcontractor
            to perform its obligations hereunder.

      (g)   LICENSES.  It will hold all  national,  provincial,  local and other
            Permits  required to allow it to operate or conduct its business now
            and as contemplated by this Contract.

                  obstacles  to  construction,   and  other  general  and  local
                  conditions  (including labor,  safety and environmental)  that
                  might affect its  performance  of the Work; but the Contractor
                  has not carried out a detailed  survey of the  proposed  route
                  and has not established whether  unconditional  Wayleaves will
                  be available for the whole of the proposed route; accordingly,
                  the Contractor does not warrant that the whole of the proposed
                  route will be suitable  or  feasible  and does not warrant the
                  precise nature or scope of the work which will be required.

      in force any of the  insurance  required by this Section 41, the Developer
      may, without  prejudice to any other rights it or any Owner may have under

      conditions  and  guaranties  contained  in all  policies  relating  to the

      remedy any such loss or damage with due  diligence  and dispatch and shall

      of  any  insurer   providing   insurance   for  the   Contractor   or  any
      Subcontractor,  or  failure of any such  insurer  to pay claims  accruing,
      shall not be  considered  a waiver of, nor shall it excuse the  Contractor


                                       67
<PAGE>

      from complying with, any of the provisions of this Contract.

     NOW,  THEREFORE,  the parties,  in consideration of the mutual undertakings
herein expressed, covenant and agree with each other as follows:

     1. ADDENDUM TO THE AMENDED EPC CONTRACT.  The Amended EPC Contract shall be
and hereby is amended as follows:

     deleted  in  its  entirety  and  the  following  language  shall  be and is
     substituted therefor:

          "9.2 ACCESS TO RECORDS.  The  Contractor  shall,  during the period in
     which  Contractor  is  required  to compile and  maintain  books,  records,
     vouchers  and  accounts  pursuant to Section  9.1  hereof,  give each Owner
     Person  access  to all  documentation  and  records  required  to be  kept,
     obtained and maintained pursuant to Section 9.1 hereof; PROVIDED,  HOWEVER,
     that with respect to all such books,  vouchers,  documentation  and records

     Owner  Persons to the extent and in the form it exists and to provide it in
     a format the Developer or such Owner Person may reasonably  request, to the
     extent to which it has not previously been delivered.  The Contractor shall
     not  destroy  any such  documentation  or  records  without  affording  the
     Developer an  opportunity  to review or copy the same.  At the  Developer's
     request, prior to Final Acceptance, copies of all documentation and records
     required to be kept, obtained and maintained pursuant to Section 9.1 hereof
     shall  be  delivered  to the  Developer  (subject  to  any  confidentiality
     obligations under Section 42 hereof).



<PAGE>

          Notwithstanding any of the foregoing, with respect to the Pre-Contract
     Execution  Period,  the  Contractor  shall be relieved of any obligation to
     provide any Owner Person with access to or copies of  documentation  of the

     was  in  existence  during  the   Pre-Contract   Execution  Period  and  in
     Contractor's  possession,  the provisions of the first paragraph of Section
     9.1 hereof shall apply to such documentation."

1.2  The definition of "Warranty  Period"  contained in Exhibit 1 to the Amended
     EPC  Contract  shall  be and is  hereby  deleted  in its  entirety  and the
     following language shall be and is substituted therefor:

            "WARRANTY  PERIOD" [REDACTED]

     2.  REFERENCE TO AND EFFECT ON THE AMENDED EPC CONTRACT.  Each reference in
the  Amended EPC  Contract  to "the  Contract,"  "this  Contract,"  "hereunder,"

      the  Developer  or the Owners to  perform  or comply  with any term of any
      Relevant Agreement;

            (iii)  Any  waiver,  consent,  extension,  indulgence,   compromise,
      release or other  action or inaction  under or in respect of any  Relevant
      Agreement or any  obligation or liability of the Contractor or the Owners,
      or any exercise or non-exercise of any right,  remedy,  power or privilege

      obligation or liability;

                                       2
<PAGE>

            (iv)  Any  bankruptcy,  insolvency,   reorganization,   arrangement,
      readjustment,  composition, liquidation or similar proceeding with respect

      of their  respective  properties or creditors,  or any action taken by any
      trustee or receiver or by any court in any such proceeding;

            (v)   Any   discharge,   termination,   cancellation,   frustration,
      irregularity, invalidity, unenforceability, illegality or impossibility of
      performance, in whole or in part, of any Relevant Agreement;

      (vi) Any  dissolution,  merger  or  consolidation  (whether  permitted  or
      otherwise)  of the  Contractor  or the  Guarantor  into or with any  other
      Person  or any  sale,  lease  or  transfer  of any  of the  assets  of the
      Contractor or the Guarantor to any other Person;

            (vii) Any change in the ownership of the Contractor;

            (viii) Any payment by the Guarantor to the  Contractor or the Owners
      pursuant to an agreement other than this Guarantee; or

            (ix)  Any  other  occurrence  or  circumstance  whatsoever,  whether
      similar or dissimilar to the foregoing,  that might otherwise constitute a
      legal or equitable  defense or discharge of the liabilities of a guarantor
      or surety or that might otherwise limit recourse against the Guarantor.

      (c) WAIVERS BY THE GUARANTOR.  To the extent  permitted by applicable law,
the Guarantor  hereby  unconditionally  waives and agrees to waive at any future
time any and all rights that the  Guarantor  may have or that now or at any time
hereafter  may  be  conferred  upon  it,  by  applicable  law or  otherwise,  to
terminate,  cancel,  quit or  surrender  this  Guarantee.  Without  limiting the
generality  of the  foregoing,  it is agreed  that,  at any time or from time to
time, the occurrence or existence of any one or more of the following  shall not
release,  relieve or discharge the Guarantor from liability  hereunder,  and the
Guarantor  hereby  unconditionally  waives  and  agrees to waive,  to the extent
permitted by applicable law:

            (i)   Notice  of  any  of the matters  referred  to  in Section 2(b)
      hereof;

            (ii)  All  notices  that  may  be  required  by  applicable  law  or
      otherwise,  now or  hereafter  in effect,  to  preserve  intact any rights
      against  the  Guarantor   including,   without  limitation,   any  demand,
      presentment and protest,  proof of notice of nonpayment under any Relevant
      Agreement,  and  notice  of any  default  or  failure  on the  part of the
      Contractor  to perform and comply with any  covenant,  agreement,  term or
      condition of the EPC Contract;

            (iii) The enforcement,  assertion or exercise against the Contractor
      of any  right,  power,  privilege  or  remedy  conferred  in any  Relevant
      Agreement or otherwise;

            (iv)  Any requirement of diligence on the part of any Person;

                                       3
<PAGE>

             (v)   Any requirement to proceed  against the  Contractor  prior to
      proceeding  against the Guarantor or any other  guarantee or to utilize or
      exhaust any remedies;

            (vi)  Acceptance of this Guarantee by the Owners; or

           (vii)  Any other  occurrence   or  circumstance  whatsoever,  whether
      similar or dissimilar to the foregoing,  that might otherwise constitute a
      legal or equitable discharge, release or defense of a guarantor or surety,
      or that might otherwise limit recourse against the Guarantor.

The  Guarantor  hereby agrees that a separate  action may be brought  against it
whether or not an action is commenced against the Contractor with respect to any
of the  Guaranteed  Obligations.  It is the intention  hereof that the Guarantor
shall remain liable as principal  until the full  performance  of the Guaranteed
Obligations.

      (d)  REINSTATEMENT  OF  GUARANTEE.  This  Guarantee  shall  continue to be
effective, or be reinstated,  as the case may be, if at any time payment, or any
part  thereof,  of  any of the  Guaranteed  Obligations  is  rescinded  or  must
otherwise be restored or returned by the recipient  thereof upon the insolvency,
bankruptcy,  dissolution,  liquidation or reorganization  of the Contractor,  or
upon or as a result of the appointment of a custodian,  receiver,  intervenor or
conservator  of, or  trustee or  similar  officer  for,  the  Contractor  or any
substantial  part of its property,  or upon any  settlement or compromise of any
claim effected by the Owners in connection with any such insolvency, bankruptcy,
dissolution, liquidation or reorganization with any claimant (including, without
limitation,  the  Contractor) or otherwise,  all as though such payments had not
been made. If any event  specified in the immediately  preceding  sentence shall
occur, and such occurrence shall prevent, delay or otherwise affect the right of
the Owners to receive any payment in respect of any Guaranteed  Obligation,  the
Guarantor  agrees  that,  for  purposes of this  Guarantee  and its  obligations
hereunder and notwithstanding the occurrence of any of the foregoing events, the
Guarantor shall  forthwith pay any such Guaranteed  Obligation at such times and
in such amounts as are specified in the EPC Contract.

      (e) NO  SUBROGATION.  Notwithstanding  anything  to the  contrary  in this
Guarantee,  the  Guarantor  hereby  irrevocably  waives all rights that may have
arisen in connection  with this  Guarantee to be subrogated to any of the rights
(whether contractual, under the Bankruptcy Code (including Section 509 thereof),
under common law or otherwise) of the Owners  against the  Contractor or against
any collateral  security or guarantee held by the Owners for the  performance of
the  Guaranteed  Obligations.  So  long  as the  Guaranteed  Obligations  remain
outstanding,  if any amount shall be paid by or on behalf of the  Contractor  to
the Guarantor on account of any of the rights waived in this Section 2(e),  such
amount shall be held by the Guarantor in trust,  segregated  from other funds of
the Guarantor,  and shall,  forthwith  upon receipt by the Guarantor,  be turned
over to the Owners in the exact form received by the Guarantor (duly indorsed by
the Guarantor to the Owners, if required),  to be applied against the Guaranteed
Obligations  in such order as the Owners may  determine.  The provisions of this
Section 2(e) shall survive the term of this Guarantee and the payment in full of
the Guaranteed Obligations.

                                       4
<PAGE>

      (f) LIMITATIONS.  Notwithstanding  the foregoing or any other provision of
this Guarantee:

            (i) The  Guarantor's  obligations  hereunder  shall  be  excused  or
      reduced  to  the  extent  that  the  Contractor's  obligations  under  the
      Guaranteed  Obligations  are excused or reduced,  whether  pursuant to the
      terms of the EPC  Contract,  or under law,  except those  available at law
      relating to the lack of validity or  enforceability  of the  obligation of
      the Contractor under or with respect to the EPC Contract; and

            (ii) Without limiting the generality of the foregoing, the Guarantor
      shall be entitled to all defenses,  set-offs,  recoupments  and deductions
      available to the  Contractor  under the EPC  Contract.  In  addition,  any
      indemnity or release given by the Owners in favor of the Contractor in the
      EPC Contract shall inure to the benefit of the Guarantor and any provision
      of the EPC Contract which limits the liability of the Contractor connected
      with any event shall  constitute  and be deemed an aggregate  limit on the
      cumulative liabilities of Contractor and Guarantor relating to such event.

            (iii) Payment or performance of any of the Guaranteed Obligations or
      other obligations, duties, liabilities,  covenants or agreements under the
      EPC  Contract  or  other  acts  which  toll  any  statute  of  limitations
      applicable  to  the  Guaranteed   Obligations  or  the  liability  of  the
      Contractor  under  the EPC  Contract,  shall  also  toll  the  statute  of
      limitations applicable to the Guarantor's liability under this Guarantee.

      SECTION 3. RIGHTS OF THIRD PARTIES.  This Guarantee shall not be construed
to create any right in any Person  other than the Owners or to be a contract  in
whole or in part for the benefit of any Person other than the Owners.

      SECTION 4. REPRESENTATIONS AND WARRANTIES. The Guarantor hereby represents
and warrants to the Owners as follows:

      (a) ORGANIZATION; POWER AND AUTHORITY. The Guarantor is a corporation duly
      organized,  validly  existing and in good  standing  under the laws of the
      State of Nevada and is qualified  to do business in the United  States and
      has all requisite  legal power and authority to execute this Guarantee and
      to perform the terms, conditions and provisions hereof.

      (b)  AUTHORIZATION.  The  execution  and delivery by the Guarantor of this
      Guarantee have been duly authorized by all requisite corporate action.

      (c)  ENFORCEABILITY.  This  Guarantee  constitutes  the  legal,  valid and
      binding obligation of the Guarantor,  enforceable against the Guarantor in
      accordance  with its  terms,  except as  enforceability  may be limited by
      applicable  bankruptcy,  insolvency,  reorganization,  moratorium or other
      similar laws affecting  creditors' rights generally and to the extent that
      the remedies of specific performance, injunctive relief and other forms of
      equitable relief are subject to equitable defenses,  the discretion of the
      court  before  which  any  proceeding  therefor  may be  brought,  and the
      principles of equity in general.

                                       5
<PAGE>

      (d) NO CONFLICT.  Neither the  execution,  delivery or  performance by the
      Guarantor of this  Guarantee,  nor the  consummation  of the  transactions
      contemplated thereby, will result in:

            (i) A  violation  of,  or a  conflict  with,  any  provision  of the
            organizational documents of the Guarantor;

            (ii) A contravention  or breach of, or a default under,  any term or
            provision of any material contract, agreement or instrument to which
            the  Guarantor  is a party  or by which  it or its  property  may be
            bound,  which  contravention,  breach or default could be reasonably
            expected  to have a material  adverse  effect on the  ability of the
            Guarantor  to  perform  its  obligations  under  this  Guarantee  to
            consummate the transactions contemplated by this Guarantee; or

            (iii) A violation by the Guarantor of any Law.

      (e) NO  VIOLATION  OF LAW.  The  Guarantor  is not in violation of any Law
      promulgated,  or judgment entered,  by any Governmental  Authority,  which
      violations, individually or in the aggregate, would adversely affect it or
      its performance of any obligations under this Guarantee.

      (f) LITIGATION. There are no actions, suits or proceedings, now pending or
      (to its best knowledge)  threatened against the Guarantor before any court
      or  administrative   body  or  arbitral  tribunal  that  might  materially
      adversely  affect the ability of the Guarantor to perform its  obligations
      under this Guarantee.

      SECTION 5.  ASSIGNMENT.  (a)  GENERALLY.  The Guarantor may not assign its
rights and obligations under this Guarantee, directly or indirectly,  whether by
pledge,  assignment,  sale  of  assets  or the  sale  or  merger  (statutory  or
otherwise),  without  the prior  written  consent of the Owners.  The  Guarantor

     with respect to any  Collateral  credited or required to be credited to the
     Collateral  Account.  Collateral  Agent  agrees  that  it  shall  take  all
     entitlement  orders with respect to the Collateral Account or any financial
     asset  credited  thereto or  required to be  credited  thereto  solely from
     Contractor  and that it will not transfer or release any  Collateral to the
     Owners or any other Person,  except in accordance with an entitlement order
     from Contractor.

          (x) Collateral Agent represents,  warrants and agrees that it does not
     currently  hold, and during the existence of this Agreement shall not hold,
     any "adverse interest", by way of security, setoff or otherwise, in (A) the
     Collateral  Account or in any financial  asset credited  thereto or carried
     therein,  or (B) in other  Collateral,  and hereby  waives and releases any
     such interest which it may have in any of the foregoing.  Without prejudice
     to the  preceding  sentence  in the  event  that  Collateral  Agent  has or
     subsequently obtains by agreement, operation of law or otherwise a security
     interest in the  Collateral  Account or any security  entitlement  credited
     thereto  or carried  therein,  Collateral  Agent  hereby  agrees  that such
     security  interest shall be subordinate  to the security  interest  granted
     herein to the Contractor.  The financial assets and other items credited to
     or  carried in the  Collateral  Account  will not be subject to  deduction,
     setoff, banker's Lien, or any other right in favor of any Person other than
     Contractor.

          (xi)  Except for the claims and  interests  of  Contractor  and of the
     Owners in the Collateral Account,  Collateral Agent represents and warrants
     that it does not know of any claim  to,  or  interest  in,  the  Collateral
     Account or in any  financial  asset  credited  thereto or carried  therein.
     Collateral  Agent  will  not (A)  permit  any of its  creditors  to  obtain


                                     - 5 -
<PAGE>

     "control"  (as such term is defined in Articles 8 and 9 of the NYUCC ) over
     the Collateral  Account or any financial asset credited  thereto or carried
     therein, or (B) enter into any agreement, arrangement or understanding with
     any other  Person  relating to any part of the  Collateral  Account and the
     financial  assets  credited  or to be  credited  thereto  or to be  carried
     therein pursuant to which it has agreed to comply with  entitlement  orders
     of such Person. If any Person asserts any Lien or adverse claim against the
     Collateral  Account  or any  financial  asset  credited  thereto or carried
     therein,  and  Collateral  Agent has actual  notice of such Lien or adverse
     claim,  Collateral Agent shall promptly notify Contractor and the Developer
     (on behalf of the Owners) thereof.

          (xii)  Collateral  Agent shall promptly send copies of all statements,
     confirmations and other correspondence concerning the Collateral Account or
     any financial asset credited thereto or carried therein  simultaneously  to
     Contractor and Developer (on behalf of the Owners) at the address set forth
     in Section 6.1.

          (xiii) By this  Agreement  the  parties  hereto  intend and agree that
     Contractor has obtained "control" (within the meaning of Section 8106(d) of
     the NY-UCC) of the Collateral  Account,  the financial  assets  credited or
     required to be credited to the Collateral Account and any other Collateral.

          (xiv)  Collateral  Agent  confirms and agrees that the first  priority
     security  interest of Contractor with respect to the Collateral is and will
     remain reflected in its books and records.

          (xv) By this  Agreement  the  parties  hereto  intend and  agree,  and
     Collateral  Agent  confirms,  that Contractor is the  "entitlement  holder"
     (within the meaning of Section  8102(a)(7) of the NY-UCC) of the Collateral
     Account and all financial  assets held by Collateral Agent hereunder as the
     securities intermediary.

     (b)  NOTICE  OF  SECURITY  INTEREST.   Collateral  Agent  (i)  acknowledges
Contractor's   security  interest  in  the  Collateral  Account  and  the  other
Collateral  granted by the Owners pursuant to Section 3.2, (ii) shall record the
pledge of the  Collateral  Account and the other  Collateral  made hereby on its
books and  (iii)  agrees to  execute  and  deliver  such  acknowledgments  as is
customary in its business or as Contractor may reasonably request.

     3.2. COLLATERAL; PLEDGE; NO LIENS; TITLE

     (a) PLEDGE.  As collateral  security for the prompt payment when due of all
amounts from time to time payable by the Owners to  Contractor  under  Section 2
and 3.12 of this Agreement and of all Owner Payment  Obligations  (collectively,
the "SECURED  OBLIGATIONS"),  the Owners  hereby  pledge,  hypothecate,  assign,
transfer, set over and deliver unto Contractor, and grant to Contractor, a first
priority  security  interest  in,  Lien  upon and right of set off  against  the
following (collectively, the "COLLATERAL"):

          (i) the Collateral Account,  including any credit or other balances of
     account  credited  thereto or carried  therein or other  amounts  otherwise
     transferred thereto;



                                     - 6 -
<PAGE>

          (ii) all investment property,  cash,  Permitted  Investments and other
     instruments  or amounts  or other  Property  deposited  or  required  to be
     deposited  from time to time in, or  credited to or required to be credited
     from  time to time to,  the  Collateral  Account  and held or to be held by
     Collateral Agent hereunder and all income therefrom;

          (iii) the Owners' securities entitlement with respect to the financial
     assets  credited  or  required  to be  credited  from  time  to time to the
     Collateral Account;

          (iv) all rights,  claims and causes of action, if any, that the Owners
     may have against any Person in respect of the foregoing; and

          (v) all proceeds of any or all of the foregoing.

     TO HAVE AND TO HOLD the  Collateral,  together  with  all  rights,  titles,
interests,  powers, privileges and preferences pertaining or incidental thereto,
unto Contractor,  its successors and assigns,  forever; subject, however, to the
terms, covenants and conditions hereinafter set forth.

     (b) LIENS,  ETC.  The Owners  agree not to  withdraw  (except as  expressly
provided for pursuant to Section  3.5(a)),  liquidate,  sell,  convey,  endorse,
negotiate,  or in any way dispose of, or create,  incur,  or permit to exist any
pledge, mortgage, Lien, charge,  encumbrance or security interest whatsoever, or
cause  any  of  the  foregoing  to  occur  in or  with  respect  to,  any of the
Collateral,  any  interest  therein  or any  cash or  other  property  held  and
maintained in or credited to the Collateral  Account.  The Owners agree at their
own expense, to defend  Contractor's  security interest in and to the Collateral
against the claims of any Person and to ensure that  Contractor has at all times
a first  priority  perfected  Lien on and security  interest in the  Collateral,
subject to no prior or equal Lien whatsoever.

     (c) TITLE.  The Owners hereby  represent and warrant to Contractor that the
Owners have good title to the Collateral and the cash or other property held and
maintained  in or  credited  to the  Collateral  Account,  free and clear of all
Liens,  other than the Lien created  hereby,  and that this Agreement  grants to
Contractor  a first  priority  perfected  Lien on and  security  interest in the
Collateral, subject to no prior or equal Lien whatsoever.

     3.3. INVESTMENTS.

     (a)  GENERALLY.  The Owners and Contractor  agree that all funds  deposited
into the  Collateral  Account shall be invested and  reinvested,  and Contractor
hereby  instructs  Collateral  Agent to so invest  and  reinvest  such  funds in
Permitted Investments.  All earnings on such investment or reinvestment shall be
paid  to the  Collateral  Account  as  part of the  Collateral.  Contractor  and
Collateral Agent shall have no liability for any losses or liabilities  incurred
as a result  of such  investments  (excluding  losses  resulting  from the gross
negligence or willful misconduct of Contractor or Collateral Agent).

     (b) INVESTMENT OF COLLATERAL. All interest,  dividends and distributions of
property on or in respect of the Collateral,  whether constituting  scheduled or


                                     - 7 -
<PAGE>

unscheduled  payments and whether received in exchange for the Collateral or any
part thereof or as a result of any merger,  consolidation,  acquisition or other
exchange of assets or on the liquidation,  whether voluntary or involuntary,  of
any issuer of the Collateral, or otherwise, and all amounts received pursuant to
Section 3.7, shall constitute Collateral  hereunder,  shall be promptly credited
to the  Collateral  Account  and shall be  applied  to the  prompt  purchase  of
Permitted Investments. Contractor hereby instructs Collateral Agent to invest in
such  Permitted  Investments as shall be directed by Developer (on behalf of the
Owners) from time to time until such time that  Contractor  otherwise  instructs
Collateral Agent. Contractor shall not instruct Collateral Agent to not act upon
Developer's  direction (on behalf of the Owners) in connection with investing in
Permitted Investments so long as no Default has occurred and is continuing.

     3.4  TERMINATION  OF  COLLATERAL  ACCOUNT.  At the request of Developer (on
behalf of the Owners)  given to  Contractor  on or after the  Termination  Date,
Contractor shall deliver prompt written notice of such termination to Collateral
Agent (a "TERMINATION NOTICE"),  whereupon the Collateral shall be released from
the Lien of this  Agreement,  and  Collateral  Agent shall  promptly  deliver to
Developer  (on behalf of the Owners) or its  designee  each of the  certificates
evidencing  the  Collateral,  as  well as any  other  instruments  or  documents
delivered to Contractor pursuant to this Agreement.

     3.5 RELEASE OF COLLATERAL

     (a)  PERIODIC  RELEASE.  If at any time during any Deposit  Date Period the
Fair Market Value of the Permitted  Investments  (and other  Collateral,  if any
credited to the  Collateral  Account as to which the  Contractor has a perfected
security  interest) is greater than the Required  Amount set forth  opposite the
Deposit Date for such  Deposit  Date Period,  as set forth in SCHEDULE I hereto,
and the  Collateral  Agent has not received a notice that a Default has occurred
and is continuing, then, upon delivery of a certificate in the form of EXHIBIT A
executed  by a person  whose  authority  to  execute  such  certificate  for the
Developer  (on  behalf  of the  Owners)  is  evidenced  by an  extract  from the
Handelsregister,  the  Contractor  hereby  instructs  the  Collateral  Agent  to
transfer the amount of such excess to the account identified in such certificate
within two Business Days and shall sell any such Permitted Investments as may be
required in order to make such transfer. The Collateral Agent shall send written
notice of such transfer via facsimile  and overnight  courier to the  Contractor
and the Developer immediately upon such transfer.

     (b)  PAYMENT  AMOUNT.  If at any  time  the  Collateral  Agent  receives  a
certificate  in the form of EXHIBIT B executed  by a person  purporting  to be a
duly authorized signatory of the Contractor, it shall transfer the amount stated
in such  certificate as being due and owing,  to the Payment  Account within two
Business Days and shall sell any such  Permitted  Investments as may be required
in order to make such transfer.  The Collateral  Agent shall send written notice
of such transfer via facsimile and overnight  courier to the  Contractor and the
Developer immediately upon such transfer.

     3.6 REMEDIES.

     (a) SECURED OBLIGATIONS.  Upon the occurrence of a Default,  Contractor may
take any action permitted herein with respect to the Collateral.



                                     - 8 -
<PAGE>

     (b)  REMEDIES.  If  a  Default  shall  have  occurred  and  be  continuing,
Contractor may from time to time:

          (i) sell,  assign,  transfer,  endorse  and deliver the whole or, from
     time to time,  any part of the  Collateral  at public or private sale or on
     any securities exchange,  for cash, upon credit or for other property,  for
     immediate  or future  delivery,  and for such  price or prices  and on such
     terms as Contractor in its reasonable  discretion  shall deem  appropriate;
     and (ii) instead of exercising  its remedy under clause (i) of this Section
     3.6(b), have any or all of the Collateral registered in its name or that of
     its  nominee  and/or  any cash or other  property,  transferred  to it.  To
     effectuate the foregoing, Contractor may notify Collateral Agent in writing
     that  Contractor  wishes to register or transfer the Collateral and or such
     cash or other  property to  Contractor,  whereupon  Collateral  Agent shall
     cause the same to be so  registered or  transferred  without the consent of
     the Owners or any other Person.  Whether or not the  Collateral  shall have
     been  registered  in the name of  Contractor or its nominee or such cash or
     other property shall have been transferred to Contractor, Contractor or its
     nominee shall have the right to exercise sole dominion and control over the
     Collateral,  such cash and such other property, to liquidate the Collateral
     and to receive  all  proceeds  thereof,  to receive  all such cash or other
     property  and to  exercise  all  voting  rights,  if any,  as to all of the
     Collateral, all other rights and all conversion, exchanged, subscription or
     other rights,  privileges or options  pertaining  thereto as if it were the
     absolute  owner  thereof,  including,  without  limitation,  the  right  to
     exchange  or  redeem  any  or  all  of  the  Collateral  upon  the  merger,
     consolidation,  reorganization,  recapitalization  or other readjustment of
     the issuer  thereof,  or upon the  exercise  by the  issuer  thereof of any
     right,  privilege,  or option pertaining to any of the Collateral,  and, in
     connection  therewith,  to deliver any of the  Collateral to any committee,
     depository,  transfer agent, registrar or other designated agency upon such
     terms and conditions as it may determine,  all without  liability except to
     account for property  actually received by it, but Contractor shall have no
     duty to exercise any of the  aforesaid  rights,  privileges  or options and
     shall not be responsible for any failure to do so or any delay in so doing;
     and

          (iii)  exercise any and all of the rights and remedies with respect to
     all or any part of the Collateral of a secured party under the NYUCC and or
     under other applicable law;

          provided,  however,  that nothing  herein shall be deemed to allow the
     Contractor to sell or foreclose upon any portion of the Collateral  that is
     in excess of the Secured Obligations.

     (c) SALES TO PURCHASERS UNDER  SECURITIES ACT OF 1933.  Contractor shall be
authorized  at any  sale (if it deems it  advisable  to do so) to  restrict  the
prospective  bidders or purchasers to persons who will  represent and agree that
they are purchasing the Collateral for their own account in compliance with, and
otherwise  satisfy the  requirements of, the Securities Act of 1933, as amended,


                                     - 9 -
<PAGE>

and upon  consummation  of any such  sale,  Contractor  shall  have the right to
assign, transfer, endorse and deliver to the purchaser or purchasers thereof the
Collateral so sold.

     (d) PRIVATE SALES.  The Owners hereby  acknowledge  and agree that a public
sale of the Collateral might require the filing of registration  statements with
the Securities and Exchange Commission and various state securities authorities.
Accordingly,  the Owners  hereby  expressly (i) authorize any sale of Collateral
under  this  Agreement  to be made in such a manner  as to avoid  the  foregoing
registration  requirements,  and (ii) acknowledge that such sales may be made in
one or more  privately  negotiated  transactions  without public offer which may
result in a lower overall sales price for the Collateral  than could be obtained
in a public  offering of the  Collateral.  Each such  purchaser at any such sale
shall hold the property sold absolutely free from any claim or right on the part
of Owners,  and the Owners  hereby  waive (to the extent  permitted  by law) all
rights of redemption,  stay and/or appraisal which the Owners now have or may at
any time in the future have under any law now existing or hereafter enacted.

     (e) NOTICE AND CONDUCT OF SALES. The Owners  acknowledge and agree that the
Collateral  is  of  a  type  customarily  sold  on  a  recognized   market  and,
accordingly,  to the extent  permitted  by law, the Owners  expressly  waive any
notice by  Contractor  or any other Person of sale or other  disposition  of the
Collateral  and all  other  rights or  remedies  of the  Owners  or  formalities
prescribed by law relative to sale or  disposition of the Collateral or exercise
of any other right or remedy of Contractor, and to the extent any such notice is
required and cannot be waived,  the Owners agree that if such notice is given in
the manner  provided  in Section 6.1 at least one day before the time of sale or
disposition,  such notice shall be deemed reasonable and shall fully satisfy any
requirement  for the giving of such  notice.  At any sale,  the  Collateral,  or
portion thereof to be sold, may be sold in one lot as an entirety or in separate
parcels,  as  Contractor  may in its sole  and  absolute  discretion  determine.
Contractor shall not be obligated to make any sale of the Collateral if it shall
determine  not to do so,  regardless  of the  fact  that  notice  of sale of the
Collateral may have been given.  Contractor may,  without notice or publication,
adjourn any public or private sale or cause the same to be  adjourned  from time
to time by announcement at the time and place fixed for sale, and such sale may,
without further  notice,  be made at the time and place to which the same was so
adjourned.  In case  the sale of all or any  part of the  Collateral  is made on
credit  or for  future  delivery,  the  Collateral  so sold may be  retained  by
Contractor until the sale price is paid by the purchaser or purchasers  thereof,
but  Contractor  shall not incur any  liability  in case any such  purchaser  or
purchasers shall fail to take up and pay for the Collateral so sold and, in case
of any such failure,  such Collateral may be sold again upon like notice. At any
public or private sale made pursuant to this  Agreement,  Contractor may bid for
or purchase,  free from any right of  redemption,  stay and/or  appraisal on the
part of the Owners (all said rights being also hereby waived and released to the
extent permitted by law), all or any part of the Collateral offered for sale and
may make payment on account thereof by using any amounts then due and payable to
Contractor  from  the  Owners  as a  credit  against  the  purchase  price,  and
Contractor may, upon compliance with the terms of sale, hold, retain and dispose
of such property  without further  accountability  to the Owners  therefor.  For
purposes hereof, a written notice by Contractor of purchase by Contractor or any
other  Person of all or any part of the  Collateral  shall be  treated as a sale
thereof.  As an alternative  to exercising  the power of sale herein  conferred,
Contractor  may proceed by suit or suits at law or in equity to  foreclose  this
Agreement and sell the Collateral or any portion thereof pursuant to judgment or
decree of a court or courts having competent jurisdiction.



                                     - 10 -
<PAGE>

     (f) ELECTION TO RETAIN  COLLATERAL.  The Owners  acknowledge and agree that
the exercise by  Contractor of any or all of its rights  hereunder  shall not be
deemed an  election  to retain the  Collateral  in  satisfaction  of any Secured
Obligations  secured  hereby and that any election to retain the  Collateral  in
satisfaction of any Secured Obligations secured hereby (in lieu of sale pursuant
to this Section 3.6 and application of proceeds  pursuant to Section 3.7 hereof)
shall only be deemed to have  occurred  if  Contractor  expressly  notifies  the
Owners of such election and the Owners do not object thereto.

     (g) COMPLIANCE  WITH LAW. The Owners hereby agree that any sale pursuant to
this Section 3.6 conforms to  commercially  reasonable  standards as provided in
the NYUCC.

     3.7  APPLICATION OF PROCEEDS.  The proceeds of any sale pursuant to Section
3.6 hereof of all or any part of the  Collateral  and all or any part of amounts
credited to the Collateral Account from time to time shall be paid by Collateral
Agent to Contractor upon the written request of Contractor and such amount shall
be applied by Contractor as follows:

          FIRST, to the payment of any fees due and payable to Collateral Agent;

          SECOND,  to the payment of all reasonable costs and expenses  incurred
     by Collateral  Agent and Contractor in connection  with the  enforcement of
     this Agreement, including, but not limited to, all court costs and the fees
     and  disbursements  of  counsel  for  Contractor  and  Collateral  Agent in
     connection with such enforcement;

          THIRD, to the payment in full to Contractor of all Secured Obligations
     then due and owing in such order as Contractor may determine; and

          FOURTH, following any such termination pursuant to Section 3.4 hereof,
     the  remainder,  if any,  to the  Owners  (or as the  Owners  or a court of
     competent jurisdiction may direct).

     3.8 CONTINUING SECURITY INTEREST.  This Agreement shall create a continuing
security  interest  in the  Collateral  and shall (i)  remain in full  force and
effect until termination pursuant to Section 3.4 hereto and (ii) be binding upon
the Owners and their respective  successors and assigns.  Upon such termination,
the  Owners  shall be  entitled  to the  prompt  return  of any  portion  of the
Collateral that shall not have been sold or otherwise  disposed of by Contractor
pursuant to the terms hereof.

     3.9 DELIVERY OF PERMITTED INVESTMENTS.

     (a)  CERTIFICATED  SECURITIES.  To  the  extent  that  any  portion  of the
Collateral constitutes certificated securities,  all certificates or instruments
evidencing  the same shall be in registered  form and  specifically  indorsed to
Contractor  by an effective  indorsement  and delivered  into the  possession of
Collateral Agent, to be held by Collateral Agent on behalf of Contractor for the
purpose of perfecting  the security  interests  granted to Contractor  hereunder
with  respect to such  Collateral  and disposed of pursuant to the terms of this
Agreement.

     (b)  UNCERTIFICATED  SECURITIES.  To the  extent  that any  portion  of the
Collateral  constitutes  an  uncertificated   security,   other  than  Permitted


                                     - 11 -
<PAGE>

Investments   credited  to  the  Collateral  Agent  pursuant  to  3.9(a),   such
uncertificated  security shall be registered in the name of the Collateral Agent
and credited by the Collateral Agent to the Collateral Account.

     3.10  FURTHER  ASSURANCES.  The  Owners  agree  that  they  will  join with
Contractor  in  executing  and  will  file or  record  such  notices,  financing
statements  or other  documents as may be necessary  for the  perfection  of the
security  interests  granted to Contractor  hereunder,  and as Contractor or its
counsel may  reasonably  request,  such  instruments to be in form and substance
satisfactory to Contractor. The Owners also agree that they will do such further
acts  and  things  and  execute  and  deliver  to  Contractor   such  additional
conveyances,  assignments,  agreements and  instruments as Contractor may at any
time reasonably request in connection with the administration and enforcement of
this  Agreement or relative to the Collateral or any part thereof or in order to
assure and confirm unto Contractor its rights, powers and remedies hereunder.

     3.11 ATTORNEY-IN-FACT. Contractor is hereby appointed the attorneyinfact of
the Owners (i) for any period,  for the purpose of signing  documents and taking
other action to perfect its security  interest in the Collateral and (ii) during
any period during which a Default has occurred and has been continuing,  for the
purpose of carrying out the  provisions of this  Agreement and taking any action
and executing any instruments  which  Contractor may deem necessary or advisable
to accomplish  the purposes  hereof,  which  appointment  as  attorneyinfact  is
irrevocable and coupled with an interest. Without limiting the generality of the
foregoing,  during any such period  described  in clause (ii) above,  Contractor
shall have the right and power to  receive,  endorse and collect all checks made
payable to the order of the Owners  representing  any  payment in respect of the
Collateral or the cash or other  property held and  maintained in or credited to
the  Collateral  Account  or any part of any of the  foregoing  and to give full
discharge for the same.

     3.12 EXPENSES.

     (a)  EXPENSES OF  CONTRACTOR.  The Owners  agree to pay to  Contractor  all
reasonable costs and expenses (including  reasonable expenses for legal services
of every  kind) of, or  incident  to,  the  enforcement  of,  or  protection  or
preservation of any right under, any of the provisions of this Agreement, or any
actual or attempted sale, or any exchange, enforcement,  collection,  compromise
or  settlement  in  respect  of any of the  Collateral,  and for the care of the

     3.14  ADJUSTMENTS  TO  SCHEDULES.  Developer  (on behalf of the Owners) and
Contractor  hereby agree to work together,  in good faith,  to make promptly any
necessary  adjustments  to  SCHEDULE I hereto  from time to time to reflect  any

and  Contractor  may deliver to the  Collateral  Agent a  substitute  SCHEDULE I
reflecting any such agreed to adjustments thereto.


SECTION 4.  COLLATERAL AGENT

     4.1 APPOINTMENT.  Contractor hereby appoints  Collateral Agent as its agent
for  purposes  of holding the  Collateral  on the terms and  conditions  of this
Agreement.  Collateral  Agent hereby accepts such  appointment.

     4.2 REMOVAL AND RESIGNATION.

     (a) Collateral  Agent or any successor  Collateral  Agent may resign at any
time  without  cause  by  giving  at  least 60 days'  prior  written  notice  to
Contractor,  with copies thereof to Developer,  such resignation to be effective
upon the  acceptance  of  appointment  by the successor  Collateral  Agent under
Section 4.2(b) hereof. In addition, Contractor may at any time remove Collateral
Agent without cause by an instrument in writing  delivered to Collateral  Agent,
with  copies  thereof  to  Developer,  such  removal  to be  effective  upon the
acceptance of appointment by the successor Collateral Agent under Section 4.2(b)
hereof.  In  the  case  of the  resignation  or  removal  of  Collateral  Agent,
Contractor may appoint a successor  Collateral Agent by an instrument  signed by
Contractor,   which  successor,  if  no  Default  shall  have  occurred  and  be
continuing,  shall  be  approved  by  Developer  (which  approval  shall  not be
unreasonably  withheld or delayed).  If a successor  Collateral  Agent shall not
have been  appointed  within 30 days after the giving of written  notice of such
resignation  or the  delivery of the  written  instrument  with  respect to such
removal,  Collateral  Agent,  Contractor  or Developer may apply to any court of
competent jurisdiction to appoint a successor Collateral Agent to act until such
time, if any, as a successor  shall have been appointed as above  provided.  Any
successor  Collateral  Agent so  appointed by such court shall  immediately  and
without further act be superseded by any successor Collateral Agent appointed as
above provided within one year from the date of the appointment by such court.

     (b) ACCEPTANCE OF  APPOINTMENT.  Any successor  Collateral  Agent,  however
appointed,  shall execute and deliver to the predecessor  Collateral Agent, with
copies  thereof to  Contractor  and  Developer,  an  instrument  accepting  such
appointment, and thereupon such successor Collateral Agent, without further act,
shall become vested with all the estates, properties, rights, powers, duties and
trusts of the  predecessor  Collateral  Agent in the trust  hereunder  with like
effect as if originally named Collateral Agent herein;  but  nevertheless,  upon
the  written  request  of such  successor  Collateral  Agent,  such  predecessor
Collateral  Agent shall execute and deliver an instrument  transferring  to such
successor  Collateral Agent, all Collateral held by such predecessor  Collateral
Agent.  Upon  any  such  transfer  by  a  predecessor   Collateral  Agent,  such
predecessor  Collateral  Agent shall  provide the  successor  Collateral  Agent,
Developer and Contractor an accounting of Collateral hereunder.

     (c) QUALIFICATION. Any successor Collateral Agent, however appointed, shall
be a bank  incorporated and doing business within the United States and having a


                                     - 13 -
<PAGE>

combined  capital  and  surplus  of at least  $100,000,000,  if there be such an
institution  willing,  able and  legally  qualified  to  perform  the  duties of
Collateral Agent hereunder upon reasonable or customary terms.

     4.3 WAIVER OF OFFSET RIGHTS.  Collateral  Agent hereby expressly waives any
right of  offset,  banker's  lien or other  similar  rights  that it might  have
against,  or any assignment,  security  interest or other interest that it might
have in, the Collateral.

     4.4 DEFAULT.  Collateral Agent shall have no responsibility for determining
whether a Default  shall have  occurred  and shall be  entitled to rely upon any
notice thereof delivered to it by Contractor.

     4.5 DUTIES. The duties and  responsibilities  of Collateral Agent hereunder
shall be determined solely by the express  provisions of this Agreement,  and no
other or further duties or responsibilities  shall be implied.  Collateral Agent
shall  not have any  liability  under,  no duty to  inquire  into the  terms and
provisions  of any  agreement  or  instructions,  other than as outlined in this
Agreement.  Anything in this  Agreement to the contrary  notwithstanding,  in no
event shall  Collateral  Agent be liable for special,  indirect or consequential
loss or  damage  of any  kind  whatsoever  (including  but not  limited  to lost
profits),  even if Collateral  Agent has been advised of the  likelihood of such
loss or damage and regardless of the form of action.  Collateral  Agent confirms
that it shall carry out all duties  placed  upon it  hereunder,  but  Collateral
Agent shall have no  responsibility  for  determining  whether  Contractor has a
first  priority  perfected  Lien on and  security  interest  in the  Collateral.
Collateral  Agent in its capacity as escrow agent  hereunder  shall not have any
liability for any loss sustained as a result of any investment  made pursuant to
the  instructions of the parties hereto or as a result of any liquidation of any
investment  prior to its  maturity  or for the  failure  of the  parties to give
Collateral  Agent  instructions  to invest or  reinvest  the  Collateral  or any
earnings  thereon.  Any  corporation  into  which  the  Collateral  Agent in its
individual  capacity  may  be  merged  or  converted  or  with  which  it may be
consolidated,  or any  corporation  resulting  from any  merger,  conversion  or
consolidation to which the Collateral Agent in its individual  capacity shall be
a party,  or any  corporation  to which  substantially  all the corporate  trust
business of the Collateral Agent in its individual  capacity may be transferred,
shall be the Collateral Agent under this Agreement without further act.

     4.6 INDEMNIFICATION.  The Owners shall release,  indemnify, defend and hold
harmless  Collateral Agent and each of its officers,  directors,  affiliates and
employees  (collectively  "INDEMNIFIED  PARTIES")  from and  against  any claim,
liability,  loss, damage or expense  (including  reasonable outside counsel fees
and  disbursements  of such  Indemnified  Parties)  of any  nature,  directly or
indirectly  arising  out of or  relating  to  any  act or  omission  under  this
Agreement, except for any such claim, liability, loss, damage or expense arising
out of an  Indemnified  Party's  gross  negligence or willful  misconduct.  This
provision shall survive the termination of this Agreement.

     4.7 TAX  IDENTIFICATION  NUMBERS.  Developer shall provide Collateral Agent
with Tax  Identification  Number (TIN) of the Owners as assigned by the Internal
Revenue Service.  All items of income,  gain, expense and loss recognized in the
Collateral  Account  shall be reported  to the United  States  Internal  Revenue
Service and all state and local taxing authorities under the name and TIN of the
Owners.

          (iv)  Neither the  execution or delivery by  Collateral  Agent of this

     judgment  or order  or any  judicial  or  administrative  order  or  decree
     applicable to or binding upon  Collateral  Agent or any of its  properties,
     (b)   conflicts  or  will   conflict   with  or  violate  the  articles  of

     bound, in any such case which does or will materially  adversely affect the
     financial  condition or the business or assets of  Collateral  Agent or its
     ability to perform its obligations  under this  Agreement,  (d) requires or
     will require,  on the part of Collateral Agent, the consent or approval of,

     Agent.

          (v) There are no actions, suits or proceedings pending, or to the best
     knowledge of Collateral Agent,  threatened before any court or by or before
     any other federal,  state or local government or public commission,  board,
     authority  or agency,  or any  arbitrator,  domestic or foreign,  which can
     reasonably  be expected to have a materially  adverse  effect on Collateral
     Agent's  ability to perform its  obligations  under this Agreement or which
     call into question the validity of any such agreement or instrument.

          (vi) As of the date hereof, Collateral Agent has received no notice of
     any  Lien  on any of the  Collateral  other  than  the  lien  in  favor  of

                                     - 18 -
<PAGE>

provided are  cumulative  and not exclusive of any rights or remedies  which any

     6.7  JURISDICTION.  Each of the  Owners,  Developer  and  Contractor  (each
individually a "PARTY" and collectively,  the "PARTIES") (i) hereby  irrevocably
submits itself to the  non-exclusive  jurisdiction of the United States District
Court for the  Southern  District  of New York and,  if such court does not have
jurisdiction, to the courts of the State of New York in New York County, for the
purposes of any suit,  action or other proceeding  arising out of this Agreement
or the subject matter thereof brought by any Party or its successors or assigns;
PROVIDED, HOWEVER, that the foregoing submission to jurisdiction shall not limit
the availability of any other forum with respect to enforcement of any judgment,
and (ii) to the extent  permitted by applicable law,  hereby waives,  and agrees
not to assert,  by way of motion,  as a defense,  or  otherwise,  any such suit,
action  or  proceeding   that  such  action  or  proceeding  is  brought  in  an
inconvenient forum, that the venue of the suit, action or proceeding is improper
or that this Agreement or the subject matter hereof may not be enforced in or by
such court.  Each Party agrees that its submission to  jurisdiction  is made for
the express  benefit of each of the other Parties.  Final  judgment  against any
Party in any suit in any court of competent  jurisdiction  shall be  conclusive,
and may be enforced in other jurisdictions by suit on the judgment,  a certified
or true copy of which shall be conclusive evidence of the fact and of the amount
of any  indebtedness  or liability of such Party  therein  described;  PROVIDED,
always that the  plaintiff  may at its option  bring suit,  or  institute  other
judicial  proceedings,  to enforce any such judgment against any Party or any of
its  assets in the  courts of any  country  or place  where  such  Party or such
assets,  as the case may be, may be found. All parties hereto waive their rights
to a trial by jury in connection  with any disputes  arising in connection  with
this  Agreement.  The  Developer,  and each of the  Owners,  hereby  irrevocably
appoints  Viatel,  Inc.  at the  address  set forth in Section 6.1 hereof as its
agent for  service  of  process  in  connection  with any suit,  action or other
proceeding  arising out of this Agreement or the subject matter hereof or any of
the transactions contemplated hereby and agrees that it will at all times during
the term of this Agreement  maintain a duly authorized  agent to receive service
of process.  Any and all service of  process,  and any other  notice in any such
action,  shall be given  personally  or by  registered  mail or certified  mail,
return receipt  requested,  or by any other means of mail that requires a signed
receipt,  postage  prepaid,  mailed  to  (i)  with  respect  to  Contractor  and
Collateral  Agent, at their  respective  address as provided in Section 6.1, and
(ii) with  respect to  Developer  and each  Owner,  to its agent for  service of
process at the address as identified above.

     6.8 GOVERNING LAW. This Agreement and all rights and obligations  hereunder
shall be governed by the laws of the State of New York.

     6.9 SEVERABILITY. Any provision of this Agreement which is invalid, illegal
or  unenforceable  in  any  jurisdiction  shall,  as to  such  jurisdiction,  be
ineffective  to the extent of such  invalidity,  illegality or  unenforceability
without invalidating,  prohibiting the observance of or rendering  unenforceable
the  remaining  provisions  hereof,  and  any  such  invalidity,  illegality  or
unenforceability  in  any  jurisdiction  shall  not  invalidate,   prohibit  the
observance of or render unenforceable such provision in any other jurisdiction.

     6.10  FURTHER  ASSURANCES.  Each of the  parties  hereto  shall cause to be
promptly and duly taken,  executed,  acknowledged and delivered all such further


                                     - 19 -
<PAGE>

acts,  documents  and  assurances  as the  other  party  may  from  time to time
reasonably  request  in order  to carry  out more  effectively  the  intent  and
purposes of this Agreement and the transactions contemplated hereby and thereby.

     6.11 WAIVER OF IMMUNITY. Each Owner, to the extent that it has or hereafter
may acquire any immunity (sovereign or otherwise) from any legal action, suit or
proceeding,  from  jurisdiction of any court or from setoff or any legal process
(whether service or notice,  attachment prior to judgment,  attachment in aid of
judgment,  attachment in aid to execution of judgment or otherwise) with respect
to itself or any of its  property,  whether or not held for its own account,  to
the  fullest  extent   permitted  by  applicable  law  hereby   irrevocably  and
unconditionally waives and agrees not to plead or claim such immunity in respect
of its obligations under this Agreement.

     6.12 THIRD PARTIES.  This Agreement shall not be deemed to create any right
in any person or entity  other than the  parties  hereto,  and their  respective
successors  and  assigns,  nor be  construed  in any respect to be a contract in
whole or in part for the benefit of any person or entity  other than the parties
hereto, and their respective successors and assigns.

     IN WITNESS  WHEREOF,  the parties hereto have caused their duly  authorized
officers or representatives to execute and deliver this Agreement as of the date
first above written

                         STORAGE AND MARKING PROCEDURES


SECTION I   DEFINITION

"PHYSICAL ITEM" shall have the meaning  ascribed thereto in ss. 90 of the German
Civil  Code  (BURGERLICHES  GESETZBUCH);  i.e.  an  item  of  physical  identity
("KORPERLICHER  GEGENSTAND")  which is not built into or otherwise linked to any
other  item  of  personal  or  real  property  in a way  that  would  make it an
inseparable part ("WESENTLICHER  BESTANDTEIL") of such other item of personal or
real  property  within the  meaning of ss.ss.  93 and 94,  respectively,  of the
German Civil Code.

SECTION II  MARKING OBLIGATIONS

(1) The  Contractor  shall,  and shall  cause all  Subcontractors  to, mark each
Physical Item of supply,  equipment,  material and other Work, including but not
limited to all  ducts,  cables and joints  (each an  "Item"),  in a manner  that
clearly identifies the Designated Owner of such Item.

(2) Each Item designated to be installed within the four Cable Links, except for
the HDPE ducts  described in Appendix 2, Section  3.2.2.  of this  Contract (for
which  sub-section  (3) shall apply),  shall bear a clearly legible imprint or a
securely  and durably  fixed tag with the name of the  Designated  Owner of such
Item:  Each Item  designated  to be  installed  within the first  Cable Link for
Viatel  German Asset GmbH shall bear an imprint or name tag reading  "Viatel 1".
Each Item  designated  to be  installed  within the second Cable Link for Viatel
German  Asset GmbH shall bear an imprint or name tag  reading  "Viatel  2". Each
Item  designated  to be  installed  within the Cable Link for  Metromedia  Fiber
Network  GmbH  shall  bear an  imprint  or name tag  reading  "MFN".  Each  Item
designated  to be  installed  within the Cable Link for Carrier 1 Fiber  Network
GmbH & Co. oHG shall bear an imprint or name tag reading "Carrier 1".

(3) Each of the HDPE ducts  described  in Appendix  2,  Section  3.2.2.  of this
Contract  (each a "Duct")  shall be  color-coded  in a way that  identifies  the
Designated  Owner of each Duct. The Duct  designated to be installed  within the
first  Cable  Link for  Viatel  German  Asset  GmbH shall be of light gray color
(color code:  gray). The Duct designated to be installed within the second Cable
Link for Viatel German Asset GmbH shall be of light gray and green striped color
(color code:  green).  The Duct designated to be installed within the Cable Link
for Metromedia Fiber Network GmbH shall be of light gray and black striped color
(color code:  black).  The Duct designated to be installed within the Cable Link
for  Carrier 1 Fiber  Network  GmbH & Co.  oHG shall be of light gray and yellow
striped color (color code: yellow).

(4) In order to identify the Designated  Owner of each manhole,  the entrance to
each manhole  shall be marked by clearly  visible gray,  green,  black or yellow
color spots of a minimum  diameter of 80 mm in accordance  with the  color-codes
provided in sub-section (3) above.



                                        1
<PAGE>

(5) Each Item, Duct and manhole shall be marked in accordance with  sub-sections
(1), (2), (3) and (4) above prior to being invoiced to its respective Designated
Owner pursuant to Sections 37.3 and 37.7,  respectively.  To ensure a timely and
cost-effective marking procedure,  each Item, Duct and manhole should be marked,
to the extent  possible  and  economically  reasonable,  during the stage of its
production  or assembly.  Since the Fiber Optic Cables will be supplied by or on
behalf of the  Developer  in  accordance  with  Appendix 3 hereof,  the  marking
obligations  with respect to such Fiber Optic Cables are primarily  borne by the
Developer, subject to sub-section (6) below.

(6) In order to ensure a clear  identification  of the Designated  Owner of each
Fiber Optic Cable, the Contractor shall verify,  upon the delivery of each Fiber
Optic  Cable by or on behalf of the  Developer,  that such Fiber Optic Cable has
been marked in accordance  with either  sub-section (2) above or the color codes
provided  in  sub-section  (3) above.  If such Fiber  Optic  Cable is not marked
accordingly upon such delivery,  the Contractor shall mark it in accordance with
either  sub-section  (2) or the color codes provided in  sub-section  (3) above,
whichever is more economical,  at the expense of the respective Designated Owner
prior to its assembly and installation within the respective Cable Link.

PROPOSAL TO REFER OR NOMINATE.  Proposals  shall be raised and considered in the
following manner:

     o    the appropriate senior-management  representative of the Party wishing
          to refer a matter to, nominate a candidate to serve as, an Independent

     o    the  Parties  shall meet and  endeavor in good faith to agree upon (i)
          referral of the relevant matter to an Independent Expert, and (ii) the
          person to serve as the Independent Expert;  PROVIDED,  that, if within
          ten (10) Days from the date of the notice given in accordance with the
          foregoing  paragraph,  the  Parties  have  failed  to  agree  upon  an
          Independent  Expert,  the matter  shall  forthwith  be referred to the
          dispute resolution procedures set forth in Section 38 of the Contract.

CONFIRMATION OF APPOINTMENT. Upon a person being appointed as Independent Expert
under the foregoing provisions,

     o    the Parties  forthwith  shall notify the relevant  appointee of his or
          her selection and shall request that such person  confirm  within five
          (5)  Business  Days  whether or not he or she is  willing  and able to
          accept an appointment as Independent Expert, and, to the extent that

     o    the first nominee so proposed is either  unwilling or unable to accept
          the  appointment  to act as  Independent  Expert,  or  shall  not have
          confirmed  his  or  her   willingness   and  ability  to  accept  such
          appointment  within the said period of five (5)  Business  Days,  then
          (unless the Parties are able to agree upon the  appointment of another
          Independent Expert), the matter shall be referred (by either Party) to
          the  dispute  resolution  procedures  set forth in  Section  39 of the
          Contract.

DISQUALIFICATION.  No person shall be appointed as an  Independent  Expert under
the Contract:

     o    unless he or she is qualified by education, experience and training to
          determine the matter in dispute; or

     o    if he or she has an interest or duty which would  materially  conflict
          with his or her role (including being a director, officer, employee or
          consultant to a Party or its Affiliates).

          (10) Business Days after such  Independent  Expert's  confirmation  of
          appointment, all such information,  records, statements and other data
          for which  such  Party  desires  review,  and each  Party  shall  make
          available to the Independent Expert all such additional information as
          the Independent Expert may request;

     o    the  Independent   Expert  shall  ignore  any  data,   information  or
          submissions  supplied and made after the ten (10)  Business Day period
          noted above,  unless the same are  furnished in response to a specific
          request from him or her;

     o    the  Independent  Expert  shall  make his or her  decision  as soon as
          reasonably  practicable  after receipt of sufficient  information from
          the Parties (but, in no event,  more than ten (10) Business Days after
          the  deadline  above for the Parties'  submissions  or the date of the
          Independent Expert's last request for supplemental  information),  the
          failure to so render a decision  shall  entitle  either Party to refer
          the matter to the dispute  resolution  procedures set forth in Section
          38 of the Contract;

     o    the  Independent  Expert shall be entitled to obtain such  independent
          professional  and/or  technical  advice  as he or she  may  reasonably

          shall be made in writing and a copy thereof provided simultaneously to
          the other Party.  No meeting  between the  Independent  Expert and the
          Parties or either of them,  shall take place unless all Parties have a
          reasonable opportunity to attend any such meeting.

DECISION-MAKING PROCEDURES. The following provisions shall apply:

     o    the  determination  of the Independent  Expert shall be in writing and
          shall provide full written reasons for his or her decisions;

          resolution  procedure in accordance  with the  procedures set forth in
          Section 38 of the Contract; and

     o    the  Independent  Expert shall be deemed not to be an arbitrator,  but
          shall  render his or her decision as an expert and the law relating to
          arbitration  shall not apply to the  Independent  Expert or his or her
          determination or the procedure by which he or she reaches a decision.

ALLOCATION  OF COSTS AND  EXPENSES.  The Parties shall share equally in all fees
charged by the Independent Expert in respect of any referral thereto. Each Party
shall bear the costs of providing all data, information and submissions given by

advisers to the Independent Expert shall be equally borne by the Parties.
