                              THE EXCHANGE OFFERS

     On February 22, 2000, we issued the old 12 7/8% dollar notes in an
aggregate principal amount of $100,000,000 and the old 12 7/8% euro notes in an
aggregate principal amount of (U)100,000,000. The offering of old notes was
exempt from registration under the Securities Act of 1933.

     We have agreed to use our best efforts to complete the exchange offers for
the old notes by September 19, 2000. The terms of the exchange offers, which are
specified in greater detail in the main body of this prospectus and the
accompanying letter of transmittal, include the following:

EXCHANGE OFFERS

<TABLE>
<S>                                         <C>
New Dollar Notes..........................  We are offering up to $100,000,000 principal amount of 12 7/8% senior
                                            dollar exchange notes due 2010 in exchange for a like principal
                                            amount of old 12 7/8% dollar notes.

New Euro Notes............................  We are offering up to (U)100,000,000 principal amount of 12 7/8% senior
                                            euro exchange notes due 2010 in exchange for a like principal amount
                                            of old 12 7/8% euro notes.

Exchange Procedures.......................  The procedures that you must follow to tender old notes in the
                                            exchange offers are specified in the section of this prospectus
                                            titled "The Exchange Offers."

Consequence of Failure to Exchange Old
  Notes...................................  You will continue to hold old notes which will remain subject to
                                            their existing transfer restrictions if you do not tender your old
                                            notes or you tender your old notes and they are not accepted for
                                            exchange. We will have no obligation to register the old notes after
                                            we consummate the exchange offers. See "The Exchange Offers--
                                            Consequences of Failure to Exchange."

Expiration Date...........................  Each exchange offer will expire at 5:00 p.m. New York City time, on
                                                         , 2000 unless we extend it to a later date and time.

Withdrawal................................  You may withdraw your tender of old notes at any time prior to the
                                            expiration of the exchange offer for those notes. If for any reason
                                            we do not accept any old note that you tender for exchange we will
                                            return that old note to you at our expense as promptly as practicable
                                            after the expiration or termination of the related exchange offer.

Conditions to the Exchange Offer..........  We can terminate or amend the exchange offers if at any time prior to
                                            5:00 p.m., New York City time on the expiration date, we determine
                                            that either exchange offer violates any applicable law or
                                            governmental order. In addition, we will not accept for exchange any
                                            old notes or issue any new notes if any stop order is threatened

                                            constitute a taxable exchange for U.S. federal income tax purposes.
                                            See "Certain United States Federal Income Tax Considerations."

<TABLE>
<S>                                         <C>

Guarantors................................  RSL Communications, Ltd, or RSL COM, and RSL COM U.S.A., Inc., or RSL
                                            USA.

  New Dollar Notes........................  Up to $100,000,000 principal amount of dollar denominated 12 7/8%
                                            senior exchange notes due 2010, or the new dollar notes.

  New Euro Notes..........................  Up to (U)100,000,000 principal amount of euro denominated 12 7/8% notes
                                            due 2010, or the new euro notes.

Maturity..................................  March 1, 2010.

Interest..................................  Annual rate: 12 7/8% on the principal amount.
                                            Payment frequency: Every six months on each March 1 and September 1,
                                            beginning on September 1, 2000.

Accrual of Interest.......................  Interest on each new note will accrue from the last interest payment
                                            date on which interest is paid on the old note surrendered in
                                            exchange therefor or, if no interest has been paid on such old note,
                                            from the date of the original issue of such old note. You will not
                                            receive interest on any old note we accept for exchange that would
                                            otherwise be payable on any interest payment date, the record date
                                            for which occurs on or after consummation of the exchange offer for
                                            the old notes.

Resales...................................  We believe that you may offer the new notes for resale, resell the
                                            new notes and otherwise transfer the new notes without complying with
                                            the registration and prospectus delivery provisions of the Securities
                                            Act, so long as:

                                            o you acquire the new notes in the exchange offer in the ordinary
                                              course of your business;

                                            o you are not participating in any distribution of the new notes that
                                              you obtain in the exchange offer and you do not intend to
                                              participate and have no arrangement or understanding with any
                                              person to participate in any such distribution; and

                                            o you are not affiliated with us.

New Notes Guarantees......................  Each of RSL COM and RSL USA has unconditionally guaranteed the
                                            payment of principal, interest and any other amounts owed with
                                            respect to the new notes. If RSL PLC cannot make payments on the new
                                            notes when they are due then RSL COM and RSL USA will be required to
                                            make those payments. RSL USA's guarantee of the new notes is subject
                                            to release without note holder consent if we sell 100% of RSL USA's
                                            capital stock or substantially all of its assets, or if Standard &
                                            Poor's Corporation advises us that the release of RSL USA's guarantee
                                            would not result in a downgrade of the rating of the new notes or a
                                            placement of the new notes on creditwatch with negative implications

Ranking...................................  The new notes and the new notes guarantees will rank equally with our
                                            other unsecured senior indebtedness. Our principal operations are
                                            conducted through subsidiaries. Accordingly, the new notes
                                            and the new notes guarantees will effectively rank behind all
                                            indebtedness of RSL COM's subsidiaries other than RSL PLC and RSL
                                            USA. In addition, holders of our secured obligations will have claims
                                            that rank ahead of the claims of the holders of the new notes and the
                                            new notes guarantees with respect to the assets securing those other
                                            obligations. As of December 31, 1999, on a pro forma basis after
                                            giving effect to the issuance of the old notes and RSL USA's
                                            guarantee of RSL PLC's previously issued notes:

                                            o the total amount of our outstanding liabilities (excluding those of
                                              our subsidiaries), including trade payables, would have been
                                              approximately $1.6 billion; and

                                            o the total amount of outstanding liabilities of RSL COM's
                                              subsidiaries (other than RSL PLC and RSL USA), including trade
                                              payables, would have been approximately $448.1 million.

Additional Amounts;
  Tax Redemption..........................  Payments we make pursuant to the new notes or the new notes
                                            guarantees will be made without withholding or deduction for taxes
                                            unless required by law. If withholding is required as a result of
                                            (1) a change to current law or the interpretation or administration
                                            thereof, or (2) a listing failure (as defined in the section
                                            "Description of the New Notes and the New Notes Guarantees" under the
                                            heading "Additional Amounts"), we will pay, subject to certain
                                            exceptions, additional amounts as may be necessary so that net
                                            payments will be no less than the amounts provided for in the new
                                            notes. In the event that (A) we have become or will become obligated
                                            to pay any additional amounts as a result of such change (or, in
                                            certain cases, such listing failure) and (B) we are unable to avoid
                                            such obligation to pay additional amounts by taking reasonable
                                            measures available to us, then we may redeem all, but not less than
                                            all, either or both series of new notes at any time at 100% of their
                                            principal amount plus accrued interest.

Change of Control.........................  If we sell certain assets or if we experience specific kinds of
                                            changes of control, we must offer to repurchase the new notes at a
                                            purchase price equal to 101% of their principal amount plus accrued
                                            interest, if any, to the date of purchase.

Basic Covenants...........................  Each of the new dollar notes and the new euro notes is governed by
                                            indentures that we have established with an indenture trustee. Each
                                            indenture restricts our ability to:

                                            o borrow money,

                                            o pay dividends or make distributions on our capital stock,

                                            o make investments or certain other restricted payments,

                                            o use assets as security in other transactions,

                                            o sell assets,

                                            o issue or sell capital stock of restricted subsidiaries (as
                                              defined), or effect a consolidation or merger.

- ------------------
(1)  Effective with the acquisition of a majority equity interest in RSL North
     America, in September 1995, we began to consolidate RSL North America's
     operations. From March 1995, the date of our initial investment, to
     September 1995, we accounted for our investment in RSL North America using
     the equity method of accounting.

(2)  In the third quarter of 1999, we recorded a special charge of $32.1 million
     for consolidating locations, streamlining operations and exiting certain
     product lines and distribution channels, including telemarketing and
     certain prepaid calling card plans. The charge is composed of approximately
     $13.1 million for terminating various operating leases, $12.4 million for
     the severance of 189 employees and $6.6 million for the cost of exiting
     certain product lines and other items, of which $2.0 million was associated
     with the write-off of inventory which was recorded as part of cost of
     services.

(3)  Other income--net includes the reversal of certain liabilities accrued in
     connection with our obligations under an agreement that required us to meet
     a carrier vendor's minimum usage requirements, which agreement was entered
     into by one of our subsidiaries prior to our acquisition of that
     subsidiary. During May 1997, we renegotiated the contract with this carrier
     vendor resulting in the elimination of approximately $7.0 million of
     previously accrued charges.

(4)  Extraordinary item represents primarily the premium paid to retire
     approximately $127.5 million of the original $300.0 million of the notes we
     issued in 1996.

(5)  Loss per share is calculated by dividing the loss attributable to our
     common shares (Class A common shares and Class B common shares) by the
     weighted average number of common shares outstanding, and has been
     retroactively restated to reflect a 2.19-for-one stock split in 1997.
     Shares issuable pursuant to (a) outstanding stock options, (b) unexercised
     warrants, (c) warrants to purchase 459,900 Class B common shares at an
     exercise price of $.00457 per share, subject to adjustment, issued to
     Ronald S. Lauder as consideration for his previous guarantee of a revolving
     credit facility, (d) options granted to a number of minority shareholders
     of our subsidiaries, exercisable on the occurrence of certain events, to
     exchange their shares in the respective subsidiaries for, in certain
     circumstances, Class A common shares or, in specific circumstances, cash or
     (e) incentive units, which are options granted to some of the employees of
     our subsidiaries to acquire shares of those subsidiaries or similar rights,
     some of which are exercisable currently

                                              (Footnotes continued on next page)

                                       9

<PAGE>

(Footnotes continued from previous page)

     and the right to exchange these incentive units for Class A common shares
     or, in other circumstances, at our option, cash, are not included in the
     loss per share calculation as their effect is anti-dilutive.

(6)  EBITDA, as used herein, consists of loss from operations before
     depreciation and amortization and also excludes a special charge and
     non-cash compensation recorded in 1999. Specifically, EBITDA excludes a
     $2.0 million charge for inventory write-off recorded in cost of services
     and a special charge of $30.1 million to reorganize and streamline
     operations and $23.6 million of non-cash compensation expense primarily
     attributable to deltathree.com. In addition, if the EBITDA loss of
     deltathree.com were also excluded from our results, we would have reported
     positive EBITDA for 1999 of $1.8 million. EBITDA is provided because it is
     a measure commonly used in the telecommunications industry. It is presented
     to enhance an understanding of our operating results and is not intended to
     represent cash flow or results of operations in accordance with U.S. GAAP
     for the periods indicated.

(7)  For the years ended December 31, 1995 through 1999, our earnings were
     insufficient to cover our fixed charges. The deficiency was approximately
     $9.4 million, $37.7 million, $100.0 million, $199.9 million and
     $338.8 million for the years ended December 31, 1995 through December 31,
     1999, respectively.

(8)  Capital expenditures include assets acquired through capital lease
     financing and other debt.

(9)  Restricted marketable securities held to maturity consist of U.S.
     government securities which were pledged for a three year period to secure
     the payment of interest on the principal amount of the notes we issued in
     1996.

(10) During 1998, we acquired various companies. See footnote 2 to our
     consolidated financial statements for information regarding these
     acquisitions.

(11) As of December 31, 1999, we had approximately $38 million of available
     (undrawn) borrowing capacity under our current bank and vendor facilities.
     The availability of these amounts is dependent upon our compliance with
     various financial ratios at the time of borrowing.

                                  RISK FACTORS

     An investment in the new notes involves risks, some of which could be
substantial and, if they occurred, could adversely affect our business,
financial condition or results of operations. You should carefully consider the
following information about these risks, together with the other information in
this prospectus, annual report for the year ended December 31, 1999 on Form
10-K, including the risk factors applicable to our business in general and other
documents we file with the SEC and incorporate in this prospectus by reference
before exchanging your notes for the new notes.

OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION AND
PREVENT US FROM SATISFYING OUR OBLIGATIONS, INCLUDING THE NEW NOTES.

     At December 31, 1999, we had total consolidated indebtedness of
approximately $1.2 billion ($1.4 billion after giving effect to our dollar and
euro notes offerings) and shareholders' deficit of approximately $83.6 million.
Subject to our compliance with the limitations contained in our outstanding
indebtedness, we may incur substantial amounts of additional indebtedness.

     For the years ended December 31, 1995, 1996, 1997, 1998 and 1999, our
earnings were insufficient to cover our fixed charges. The deficiency was
approximately $9.4 million for the year ended December 31, 1995, $37.7 million
for the year ended December 31, 1996, $100.0 million for the year ended December
31, 1997, $199.9 million for the year ended December 31, 1998 and
$338.8 million for the year ended December 31, 1999.

     If our operations do not generate enough revenues or we cannot obtain
sufficient funds at acceptable rates to make our debt payments when they are due
or we fail to comply with the material terms of the legal documents governing
our indebtedness, the value of our securities, including the notes, could be
adversely affected.

THE LEGAL DOCUMENTS GOVERNING OUR INDEBTEDNESS RESTRICT OUR ABILITY TO TAKE
CERTAIN ACTIONS.

     The legal documents governing our outstanding indebtedness contain
restrictive covenants which impose limitations on our ability and the ability of
most of our subsidiaries to:

     o incur additional indebtedness

     o pay dividends or make other distributions

     o issue capital stock of some of our subsidiaries

     o guarantee debt

     o enter into transactions with shareholders and affiliates

     o create liens

     o enter into sale-leaseback transactions

     o sell assets

     o make some types of investments

     As described above, these restrictions could inhibit us from raising
additional capital to fund our operations and planned expansions, which could
adversely affect our ability to generate cash to service our outstanding
indebtedness, including the notes offered hereby.

OUR ABILITY TO PAY OUR OBLIGATIONS, INCLUDING THE NOTES, DEPENDS UPON OUR
ABILITY TO RECEIVE CASH FROM OUR SUBSIDIARIES.

     Each of RSL COM and RSL PLC is a holding company and their only material
assets consist of shares of their subsidiaries and fluctuating cash balances.
RSL COM and RSL PLC have contributed or loaned to their subsidiaries a
substantial majority of the net proceeds from their prior sales of common shares
and notes. Our ability to pay our obligations, including the new notes and the
new notes guarantees, depends upon our ability to

                                       11

<PAGE>

receive cash from our subsidiaries. However, these subsidiaries may face
difficulties distributing cash to us because:

     o they are separate and distinct legal entities and may have no obligation
       to make funds available to us;

     o their ability to make distributions to us is subject to the availability
       of funds and the terms of their indebtedness;

     o their repayment of loans and advances made to them by us may be subject
       to statutory or contractual restrictions or taxation;

     o their repayment of loans and advances is contingent upon their earnings;

     o their payment of dividends to us may have adverse tax consequences; and

     o their ability to declare and pay dividends to us may be subject to legal
       restrictions or restrictions contained in organizational documents or
       loan agreements.

     If a subsidiary is liquidated or reorganized, there may not be sufficient
assets for us to recover our investment in that subsidiary. Any right we have to
receive assets from a subsidiary upon its liquidation or reorganization (and the
consequent right of the holders of the notes and the notes guarantee to those
assets) is secondary to the claims of the subsidiary's creditors, unless we are
independently recognized as a creditor. Even if we are recognized as a creditor,
our claims could be junior to claims held by other creditors.

THE NOTES AND THE NOTES GUARANTEES ARE STRUCTURALLY SUBORDINATED TO THE
OBLIGATIONS OF OUR SUBSIDIARIES.

     Because each of RSL COM and RSL PLC is a holding company and their assets
consist primarily of equity interests in their subsidiaries, the notes and the
notes guarantees will be structurally subordinated to all indebtedness and other
liabilities of their subsidiaries other than RSL USA. As of December 31, 1999,
on a pro forma basis after giving effect to the issuance of the old notes and
RSL USA's guarantee of RSL PLC's previously issued and outstanding notes:

     o the total of outstanding liabilities of RSL COM, RSL PLC and RSL USA
       (excluding liabilities of their subsidiaries), including trade payables,
       would have been approximately $1.6 billion; and

     o the total amount of outstanding liabilities of the subsidiaries of RSL
       COM (other than RSL PLC and RSL USA), including trade payables, would
       have been approximately $448.1 million.

     In certain circumstances, RSL USA's new notes guarantees could be
unenforceable or claims thereunder could be subordinated to claims of other
creditors of RSL USA.

     If, under relevant federal and state fraudulent transfer and conveyance
statutes, in a bankruptcy or reorganization case or a lawsuit by or on behalf of
unpaid creditors of RSL USA, a court were to find that, at the time RSL USA
entered into the old notes guarantees, RSL USA (a) did so with the intent of
hindering, delaying or defrauding current or future creditors or (b) (i)
received less than reasonably equivalent value or fair consideration, as
applicable, in exchange for entering into the old notes guarantees, and
(ii) (A) was insolvent or was rendered insolvent by reason of entering into the
old notes guarantees, (B) was engaged, or about to engage, in a business or
transaction for which its assets constituted unreasonably small capital,
(C) intended to incur, or believed that it would incur, debts beyond its ability
to pay as such debts matured (as all of the foregoing terms are defined in or
interpreted under the relevant fraudulent transfer or conveyance statutes) or
(D) was a defendant in an action for money damages docketed against it (if, in
either case, after final judgment the judgment is unsatisfied), such court could
avoid or subordinate RSL USA's new notes guarantees to presently existing and
future indebtedness of RSL USA and take other action detrimental to the holders
of the new notes, including, under certain circumstances, invalidating RSL USA's
new notes guarantees. The measure of insolvency for purposes of the foregoing
considerations will vary depending upon the law of the jurisdiction that is
being applied in any such proceeding. There can be no assurance as to what
standards a court would use to determine whether RSL USA was solvent at the
relevant time, or whether, whatever standard was used, RSL USA's new notes
guarantees would not be avoided on another of the grounds set forth above.

                                       12

EFFECTS OF INCORPORATION UNDER UNITED KINGDOM CORPORATE LAW.

     RSL PLC, as a United Kingdom corporation, is governed by the Companies Act
1985 of the United Kingdom. This act differs from laws generally applicable to
United States corporations and their shareholders, including regulations
relating to interested directors, mergers and indemnifications of directors.

NO PUBLIC MARKET EXISTS FOR THE NOTES.

     The new notes offered hereby are new issuances of securities for which
there is currently no active trading market. If the new notes are traded after
their initial issuance, they may trade at a discount from their initial offering
price, depending upon prevailing interest rates, the market for similar
securities and other factors, including general economic conditions and our
financial condition, performance and prospects. Even though we are obligated to
complete exchange offers or shelf registrations for the old notes by September
19, 2000, there can be no assurance that exchanges or shelf registrations will
occur in the required time period or whether, even after exchanges or
registrations are effected, an active trading market will develop for any of the
notes. The SEC has broad discretion to determine whether any registration
statement will be declared effective and may delay or deny the effectiveness of
any registration statement for a variety of reasons. Failure to have old
registration statements declared effective could adversely affect the liquidity
and prices of the notes. If we do not comply with our registration obligations
in a timely manner, we will be obligated to pay additional interest in cash on
the old notes.

IF YOU DO NOT PROPERLY TENDER YOUR OLD NOTES, YOU WILL CONTINUE TO HOLD
UNREGISTERED OLD NOTES; THE OLD NOTES ARE SUBJECT TO TRANSFER RESTRICTIONS, AND
YOUR ABILITY TO TRANSFER OLD NOTES WILL BE ADVERSELY AFFECTED.

     As old notes are tendered and accepted in the exchange offer, the trading
market for the remaining untendered or tendered but not accepted old notes will
be adversely affected. We anticipate that most holders of the old notes will
elect to exchange the old notes for new notes due to the absence of restrictions
on the resale of new notes under the Securities Act. Therefore, we anticipate
that the liquidity of the market for any old notes remaining after the
consummation of the exchange offer will be substantially limited.

     We will only issue new notes in exchange for old notes that you timely and
properly tender. Therefore, you should allow sufficient time to ensure timely
delivery of the old notes and you should carefully follow the instructions on
how to tender your old notes. Neither we nor the exchange agent are required to
tell you of any defects or irregularities with respect to your tender of the old
notes. If you do not tender your old notes for new notes in the exchange offers,
the old notes you hold will continue to be subject to the existing transfer
restrictions. In general, you may not offer or sell the old notes unless they
are registered under the Securities Act, or are exempt from registration under
the Securities Act and applicable state securities laws. If you do not tender
your old notes or they are not accepted for exchange, you will have no further
rights under the registration rights agreement. See the section "The Exchange
Offers" under the heading "Consequences of Failure to Exchange." We do not
anticipate that we will register old notes under the Securities Act.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Any statements in this prospectus about our expectations, beliefs, plans,
objectives, assumptions or future events or performance are not historical facts
and are forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934.
These statements are often, but not always, made through the use of words or
phrases such as "will likely result," "expect," "will continue," "anticipate,"
"estimate," "intend," "plan," "projection," "would" and "outlook." Accordingly,
these statements involve estimates, assumptions and uncertainties that could
cause actual results to differ materially from those expressed in them. Any
forward-looking statements are qualified in their entirety by reference to the
factors discussed throughout this document. The following cautionary statements
identify important factors that could cause our actual results to differ
materially from those projected in the forward-looking statements made in this
document. Among the key factors that have a direct bearing on our results of
operation are:

     o general economic and business conditions;

                                       13

<PAGE>

     o changes in, or failure to comply with, government regulations;

     o changes in marketing and technology in the telecommunications industry;

     o changes in political, social and economic conditions;

     o competition in the telecommunications industry;

     o general risks of the telecommunications industry;

     o success of acquisition and operating initiatives;

     o management of growth;

     o availability, terms and deployment of capital; and

     o deregulation of the telecommunications market.

     These factors and the risk factors referred to above could cause actual
results or outcomes to differ materially from those expressed in any
forward-looking statements we make. You should not place undue reliance on any
such forward-looking statements. Further, any forward-looking statement speaks
only as of the date on which it is made and we undertake no obligation to update
any forward-looking statement to reflect events or circumstances after the date
on which such statement is made or to reflect the occurrence of unanticipated
events. New factors emerge from time to time, and it is not possible for us to
predict them. In addition, we cannot assess the impact of each factor on our
business or the extent to which any factor, or combination of factors, may cause
actual results to differ materially from those contained in any forward-looking
statements.

     For a discussion of important risks of an investment in our securities,
including factors that could cause actual results to differ materially from
results referred to in the forward-looking statements, see the section in this
prospectus entitled "Risk Factors" as well as the section entitled "Risk
Factors" in our annual report for the year ended December 31, 1999 filed on Form
10-K and incorporated in this prospectus by reference. You should carefully
consider the information discussed in those sections. In light of these risks,
uncertainties and assumptions, the forward-looking events discussed in or
incorporated by reference in this offering circular might not occur.

     Throughout this prospectus we have used industry data obtained from
internal surveys, market research, publicly available information and industry
publications. Industry publications generally state that the information they
contain has been obtained from sources believed to be reliable but that the
accuracy and completeness of that information is not guaranteed. Although these
data have been correctly reproduced in this prospectus from the internal
surveys, market research, publicly available information and industry
publications, we have not independently verified the data.

                              THE EXCHANGE OFFERS

REGISTRATION RIGHTS AGREEMENT FOR OLD NOTES

     We entered into a registration rights agreement in connection with our
issuance of the old notes. This summary of provisions of the registration rights
agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the registration rights
agreement, a copy of which is incorporated by reference into the registration
statement of which this prospectus is a part.

REGISTRATION RIGHTS

     We have agreed in the registration rights agreement:

     o to file this registration statement with the SEC and use our reasonable
       best efforts to complete the exchange offers as soon as practicable, but
       no later than September 19, 2000;

     o to hold each exchange offer open for at least 30 days and exchange new
       notes for all old notes validly tendered and not withdrawn before its
       expiration; and

     o if the new notes will not be freely transferable in general upon exchange
       in the exchange offer because of a change in the SEC's interpretation of
       its rules, in lieu of effecting registration of new notes, to use our
       reasonable best efforts to effect a shelf registration of the old notes
       for resale by holders, and keep the registration effective for a period
       of up to two years ending February 22, 2002.

SHELF REGISTRATION

     In the event we effect a shelf registration we will provide holders of the
old notes copies of the prospectus that is a part of the registration statement,
notify holders when the resale registration for the old notes has become
effective and take other actions as are required to permit unrestricted resales
of the old notes. A holder that sells old notes pursuant to the resale
registration generally will be required to be named as a selling security holder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act in
connection with such sales and will be bound by the provisions of the
registration rights agreement that are applicable to such a holder (including
certain indemnification obligations).

LIQUIDATED DAMAGES

     In the event that:

     o the exchange offers are not completed by September 19, 2000 (or, if
       applicable, the resale registration is not effective within the required
       period) or

     o any resale registration required by the registration rights agreement is
       filed and declared effective but thereafter ceases to be effective
       (except as specifically permitted in the registration rights agreement)
       without being succeeded promptly by an additional registration statement
       filed and declared effective,

then interest will accrue (in addition to any stated interest on the old notes)
at the rate of 0.5% per annum, determined daily, on the principal amount at
maturity of the old notes that remain unexchanged or unregistered as required
until such notes are exchanged or become registered or their registration is no
longer required.

RESALES OF NEW NOTES ISSUED IN THE EXCHANGE OFFERS

     Based on SEC interpretations we believe that the new notes issued in the
exchange offers may be offered for resale, resold and otherwise transferred by
any holder (other than any holder that is a broker-dealer or our "affiliate"
within the meaning of Rule 405 under the Securities Act) without compliance with
the registration and prospectus delivery provisions of the Securities Act,
provided that:

     o the new notes sold are acquired in the ordinary course of business;

     o at the time of the commencement of the exchange offers the selling holder
       had no arrangement or understanding with any person to participate in a
       distribution of the new notes; and

                                       15

<PAGE>

     o the selling holder is not engaged in, and does not intend to engage in, a
       distribution of the new notes.

     We have not sought, and do not intend to seek, a no-action letter from the
Commission with respect to the effects of the exchange offers, and there can be
no assurance that the staff would make a similar determination with respect to
the new notes as it has previously in other similar offerings.

REPRESENTATIONS HOLDERS WILL MAKE WHEN THEY TENDER

     By tendering old notes in exchange for new notes and by executing the
letter of transmittal, each holder will represent to us that:

     o any new notes to be received by it will be acquired in the ordinary
       course of business;

     o it has no arrangements or understandings with any person to participate
       in the distribution of the old notes or new notes within the meaning of
       the Securities Act; and

     o it is not our "affiliate," as defined in Rule 405 under the Securities
       Act.

     Each broker-dealer that receives new notes for its own account in exchange
for old notes, where such old notes were acquired by such broker-dealer as a
result of market-making or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such new notes. Each
holder, whether or not it is a broker-dealer, shall also represent that it is
not acting on behalf of any person that could not truthfully make any of the
foregoing representations contained in this paragraph. Any holder of old notes
who is unable to make the foregoing representations and any broker-dealer who
acquired the old notes directly from us may not rely on the applicable
interpretations of the staff of the Commission and must comply with the
registration and prospectus delivery requirements of the Securities Act,
including being named as selling security holders, in order to resell the notes.

TERMS OF THE EXCHANGE OFFERS; PERIOD FOR TENDERING OLD NOTES

     Upon the terms and subject to the conditions set forth in this prospectus
and in the accompanying Letter of Transmittal, we will accept for exchange old
notes which are properly tendered on or prior to the expiration date and not
withdrawn as permitted below. As used herein, the term "expiration date" means
5:00 p.m., New York time, on                 , 2000; provided, however, that if
we, in our sole discretion, have extended the period of time for which the
exchange offer is open, the term "expiration date" means the latest time and
date to which the exchange offer is extended.

     As of the date of this prospectus, $100,000,000 aggregate principal amount
of old dollar notes and (U)100,000,000 aggregate principal amount of old euro
notes are outstanding. We are sending this prospectus, together with the letter
of transmittal, on or about             , 2000 to all holders of old notes known
to us. Our obligation to accept old notes for exchange pursuant to the exchange
offers is subject to certain conditions as set forth below under the subsection
"--Conditions."

     We expressly reserve the right, at any time or from time to time, to extend
the period of time during which an exchange offer is open, and thereby delay
acceptance for exchange of any old notes pursuant to that exchange offer, by
giving oral or written notice of any extension, amendment, non-acceptance or
termination to you as promptly as practicable, such notice in the case of any
extension to be issued by means of a press release or other public announcement
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date.

EFFECT OF TENDER

     If you tender to us old notes as set forth below, our acceptance of your
tender will constitute a binding agreement between you and us upon the terms and
conditions set forth in this prospectus and in the accompanying letter of
transmittal.

                                       16

<PAGE>

PROCEDURES FOR TENDERING

     To tender in an exchange offer, a holder must complete, sign and date the
letter of transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the letter of transmittal, and mail or otherwise
deliver the letter of transmittal or such facsimile, together with any other
required documents, to the exchange agent prior to 5:00 p.m., New York City
time, on the expiration date. A holder may tender old notes only in integral
multiples of $1,000, in the case of the old dollar notes and (U)1,000, in the
case of the old euro notes, in exchange for an equal principal amount,
respectively, of new notes. In addition, either:

     o certificates of such old notes must be received by the exchange agent
       along with the letter of transmittal; or

     o a timely confirmation of a book-entry transfer of such old notes, if such
       procedure is available, into the exchange agent's account at The
       Depository Trust Company, in the case of the old dollar notes, or
       EuroClear or Clearstream, in the case of the old euro notes, under the
       procedures for book-entry transfer described below, must be received by
       the exchange agent prior to the expiration date with the letter of
       transmittal; or

     o the holder must comply with the guaranteed delivery procedures described
       below.

     The method of delivery of old notes, letter of transmittal and all other
required documents is at the election and risk of the holders. If such delivery
is by mail, it is recommended that registered mail, properly insured, with
return receipt requested, be used. In all cases, sufficient time should be
allowed to assure timely delivery. No old notes, letters of transmittal or other
required documents should be sent to us. Delivery of all old notes, if
applicable, letters of transmittal and other documents must be made to the
exchange agent at its address set forth below. Holders may also request their
respective brokers, dealers, commercial banks, trust companies or nominees to
effect such tender for such holders.

     The tender by a holder of old notes will constitute an agreement between
such holder and us in accordance with the terms and subject to the conditions
set forth herein and in the letter of transmittal. Any beneficial owner whose
old notes are registered in the name of a broker, dealer, commercial bank, trust
company or other nominee and who wishes to tender should contact such registered
holder promptly and instruct such registered holder to tender on his behalf.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by any member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor" institution within the meaning of Rule
17Ad-15 under the Exchange Act unless the old notes tendered are tendered:

     o by a registered holder of old notes who has not completed the box
       entitled "Special Issuance Instructions" or "Special Delivery
       Instructions" on the Letter of Transmittal; or

     o for the account of an eligible guarantor institution.

     If the letter of transmittal is signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or others
acting in a fiduciary or representative capacity, such person should so indicate
with signing, and unless waived by us, evidence satisfactory to us of their
authority to so act must be submitted with the letter of transmittal.

     All questions as to the validity, form, eligibility, time of receipt and
withdrawal of the tendered old notes will be determined by us in our sole
discretion, which determination will be final and binding. We reserve the
absolute right to reject any and all old notes not properly tendered or any old
notes which, if accepted, would, in the opinion of our counsel, be unlawful. We
also reserve the absolute right to waive any irregularities or conditions of
tender as to particular old notes. Our interpretation of the terms and
conditions of the exchange offers, including the instructions in the letter of
transmittal, will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of old notes must be cured
within such time as we shall determine. Neither we, the exchange agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of old notes, nor shall any of them incur
any liability for failure

                                       17

<PAGE>

to give such notification. Tenders of old notes will not be deemed to have been
made until such irregularities have been cured or waived.

     In addition, we reserve the right in our sole discretion, subject to the
provisions of the indentures for the old notes:

     o to purchase or make offers for any old notes that remain outstanding
       subsequent to the expiration date or, as set forth under "--Conditions;"

     o to terminate the exchange offers;

     o to redeem old notes as a whole or in part at any time and from time to
       time, as set forth under "Description of the New Notes and the New Notes
       Guarantee--Optional Redemption;" and

     o to the extent permitted under applicable law, to purchase old notes in
       the open market, in privately negotiated transactions or otherwise.

     The terms of any such purchases or offers could differ from the terms of
the exchange offers.

ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES

     Upon satisfaction or waiver of all of the conditions to an exchange offer,
all old notes validly tendered pursuant to the exchange offer and not withdrawn
prior to 5:00 pm, New York City time, on the expiration date will be accepted
promptly after the expiration date, and the new notes will be issued promptly
after acceptance of the old notes. For purposes of the exchange offers, old
notes shall be deemed to have been accepted as validly tendered for exchange
when, as and if we have given oral or written notice thereof to the exchange
agent. For each old note accepted for exchange, the holder of such old note will
receive a new note having a principal amount equal to that of the surrendered
old note. In all cases, issuance of new notes for old notes that are accepted
for exchange in an exchange offer will be made only after timely receipt by the
exchange agent of the required documents.

     If any tendered old notes are not accepted for any reason, such unaccepted
or such nonexchanged old notes will be returned without expense to the tendering
holder (if in certificated form) or credited to an account maintained with The
Depositary Trust Company or Euroclear or Clearstream, as the case may be, as
promptly as practicable after nonacceptance, withdrawal of tender or the
expiration or termination of the relevant exchange offers.

BOOK-ENTRY TRANSFER

     The exchange agent will make a request to establish an account with respect
to the old notes at The Depositary Trust Company, in the case of the old dollar
notes, or Euroclear and Clearstream, in the case of the old euro notes, for
purposes of the exchange offer within two business days after the date of this
prospectus. With respect to the old dollar notes, the exchange agent and The
Depositary Trust Company have confirmed that any financial institution that is a
participant in The Depositary Trust Company may utilize The Depositary Trust
Company Automated Tender Offer Program procedures to tender old notes.

     With respect to the old dollar notes, any participant in The Depositary
Trust Company may make book-entry delivery of old dollar notes by causing The
Depositary Trust Company to transfer the old dollar notes into the exchange
agent's account in accordance with The Depositary Trust Company's Automated
Tender Offer Program procedures for transfer. With respect to the old euro
Notes, any participant in Euroclear and Clearstream may make book-entry delivery
of old euro Notes by causing Euroclear and Clearstream to transfer the old euro
Notes into the exchange agent's account in accordance with established Euroclear
and Clearstream procedures for transfer. However, the exchange for the old
dollar notes and the old euro Notes so tendered will only be made after a
book-entry confirmation of such book-entry transfer of old dollar notes or the
old euro Notes, as the case may be, into the exchange agent's account, and
timely receipt by the exchange agent of an agent's message and any other
documents required by the Letter of Transmittal. The term "agent's message"
means a message, transmitted by The Depositary Trust Company or Euroclear and
Clearstream, as the case may be, and received by the exchange agent and forming
part of a book-entry confirmation, which states that The Depositary Trust
Company or Euroclear and Clearstream, as the case may be, has received an
express acknowledgment from a

                                       18

<PAGE>

participant tendering old notes that are the subject of the book-entry
confirmation that the participant has received and agrees to be bound by the
terms of the letter of transmittal, and that we may enforce that agreement
against the participant.

GUARANTEED DELIVERY PROCEDURES

     If the procedures for book-entry transfer cannot be completed on a timely
basis, a tender may be effected if:

     o the tender is made through an eligible institution;

     o prior to the expiration date, the exchange agent receives by facsimile
       transmission, mail or hand delivery from such eligible institution a
       properly completed and duly executed Letter of Transmittal and notice of
       guaranteed delivery, substantially in the form provided by us that:

          1. sets forth the name and address of the holder of old notes and the
     amount of old notes tendered;

          2. states that the tender is being made thereby; and

          3. guarantees that within three New York Stock Exchange trading days
     after the date of execution of the notice of guaranteed delivery, the
     certificates for all physically tendered old notes, in proper form for
     transfer, or a book-entry confirmation, as the case may be, and any other
     documents required by the letter of transmittal will be deposited by the
     eligible institution with the exchange agent; and

          4. the certificates for all physically tendered old notes, in proper
     form for transfer, or a book-entry confirmation, as the case may be, and
     all other documents required by the Letter of Transmittal are received by
     the exchange agent within three New York Stock Exchange trading days after
     the date of execution of the notice of guaranteed delivery.

WITHDRAWAL OF TENDERS

     Tenders of old notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the expiration date of the exchange offer for those old
notes.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent prior to 5:00 p.m., New York City time on the
expiration date at one of the addresses set forth below under "--Exchange
Agent." Any such notice of withdrawal must:

     o specify the name of the person having tendered the old notes to be
       withdrawn;

     o identify the old notes to be withdrawn, including the principal amount of
       such old notes;

     o in the case of old notes tendered by book-entry transfer, specify the
       number of the account at The Depositary Trust Company or Euroclear or
       Clearstream, as the case may be, from which the old notes were tendered
       and specify the name and number of the account at The Depositary Trust
       Company or Euroclear or Clearstream, as the case may be, to be credited
       with the withdrawn old notes and otherwise comply with the procedures of
       such facility;

     o contain a statement that the holder is withdrawing its election to have
       the old notes exchanged;

     o be signed by the holder in the same manner as the original signature on
       the letter of transmittal by which the old notes were tendered, including
       any required signature guarantees, or be accompanied by documents of
       transfer to have the trustee with respect to the old notes register the
       transfer of the old notes in the name of the person withdrawing the
       tender; and

     o specify the name in which the old notes are registered, if different from
       the person who tendered the old notes.

     All questions as to the validity, form, eligibility and time of receipt of
such notice will be determined by us and our determination shall be final and
binding on all parties. Any old notes so withdrawn will be deemed not to have
been validly tendered for exchange for purposes of the exchange offer. Properly
withdrawn old notes may be retendered by following one of the procedures
described under "--Procedures for Tendering" and

                                       19

<PAGE>

"--Book-Entry Transfer" above at any time on or prior to 5:00 p.m., New York
City time, on the expiration date of the exchange offer for those old notes.

CONDITIONS

     The exchange offers are not conditioned upon any minimum principal amount
of old notes being tendered for exchange. Notwithstanding any other provision of
the exchange offers, we shall not be required to accept for exchange, or to
issue new notes in exchange for, any old notes and may terminate or amend the
exchange offer if at any time prior to 5:00 p.m., New York City time, on the
relevant expiration date, we determine that the exchange offer violates
applicable law, any applicable interpretation of the staff of the SEC or any
order of any governmental agency or court of competent jurisdiction.

     In addition, we will not accept for exchange any old notes tendered, and no
new notes will be issued in exchange for any such old notes, if at such time any
stop order shall be threatened or in effect with respect to the registration
statement of which this prospectus constitutes a part or the qualification of
the indenture under the Trust Indenture Act of 1939. We are required to use
every reasonable effort to obtain the withdrawal of any order suspending the
effectiveness of the registration statement at the earliest possible moment.

     Delivery of the Letter of Transmittal to an address other than as set forth
above or transmission of instructions via facsimile other than as set forth
above does not constitute a valid delivery of such Letter of Transmittal.

FEES AND EXPENSES

     We will not make any payment to brokers, dealers, or others soliciting
acceptances of the exchange offer.

     We will pay the estimated cash expenses to be incurred in connection with
the exchange offers, which are estimated in the aggregate to be approximately
$100,000.

TRANSFER TAXES

     Holders who tender their old notes for exchange will not be obligated to
pay any transfer taxes in connection therewith, except that holders who instruct
RSL PLC to register new notes in the name of, or request that old notes not
tendered or not accepted in the exchange offer be returned to, a person other
than the registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.

CONSEQUENCES OF FAILURE TO EXCHANGE

     We will have no obligation to register old notes after we complete the
exchange offers. Holders of old notes who do not exchange their old notes for
new notes in the exchange offers will continue to be subject to the restrictions
on transfer of those old notes as set forth in the legend on the old notes as a
consequence of the issuance of the old notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
and applicable state securities laws. In general, the old notes may not be
offered or sold, unless registered under the Securities Act, except in an
exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. We do not anticipate that we will register the
old notes under the Securities Act. To the extent that old notes are tendered
and accepted in the exchange offers, the trading market for untendered and
tendered but unaccepted old notes will be adversely affected.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

CREDIT FACILITIES

     One of our primary equipment vendors has provided to certain of our
subsidiaries financing commitments to fund the purchase of additional switches
and related equipment. As of December 31, 1999, such commitments were in the
aggregate limited to approximately $85 million, all of which had been drawn.
Borrowings from this equipment vendor will accrue interest at a rate of LIBOR
plus 3.5% to 5.25%, depending on the equipment purchased and whether the loan is
guaranteed by the Swedish Export Credits Guarantee Board. Through Telegate, we
have $26 million of revolving credit facilities with various banks, all of which
was available at December 31, 1999. Through RSL COM Canada, we also have a $6.9
million revolving credit facility that accrues interest at an annual rate of
8.7%, $1.6 million of which was available at December 31, 1999.

pursuant to an indenture, dated October 3, 1996, or the 1996 Indenture, among
RSL PLC, RSL COM and The Chase Manhattan Bank, as trustee, which were exchanged
on May 22, 1997 for $300.0 million of substantially identical notes that had
been registered under the Securities Act, or the 1996 Notes, of which
$172.5 million in aggregate principal amount remain outstanding as of the date

unconditionally guaranteed the 1996 Notes.

  PRINCIPAL, MATURITY AND INTEREST

     The 1996 Notes are limited in aggregate principal amount to $300.0 million
and will mature on October 3, 2006. Interest on the 1996 Notes accrues at
12 1/4% per annum and is payable semiannually in arrears on May 15 and November
15 of each year. Interest is computed on the basis of a 360-day year comprised
of twelve 30-day months. RSL PLC used $102.8 million of the net proceeds of the
1996 Notes to purchase a portfolio of securities, initially consisting of U.S.
government securities, to pledge as security for payment of interest on the
principal of the 1996 Notes. Proceeds from the pledged securities have been used
by RSL PLC to make interest payments on the 1996 Notes through November 15,
1999.

right of payment with all existing and future senior obligations of RSL PLC, and
rank senior in right of payment to all of the future subordinated obligations of
RSL PLC and RSL COM.

  REDEMPTION

     The 1996 Notes are not redeemable prior to November 15, 2001. Thereafter,

will accrue on the principal amount at maturity of such notes at the rate of
10 1/2% per annum and is payable semiannually on May 15 and November 15 of each
year. Interest is computed on the basis of a 360-day year comprised of twelve
30-day months.

COM receives net cash proceeds from the public or private sale of its common
stock, RSL PLC may (to the extent it receives such proceeds and has not used
them, directly or indirectly, to redeem or repurchase other securities pursuant
to optional redemption provided), at its option, apply an amount equal to any
such net cash proceeds or any portion thereof to redeem, from time to time,
10 1/2% Notes in a principal amount at maturity of up to an aggregate amount
equal to one-third of the aggregate principal amount at maturity of the 10 1/2%
Notes, provided, however, that 10 1/2% Notes in an amount equal to at least
two-thirds of the aggregate principal amount at maturity of the 10 1/2% Notes
remain outstanding immediately after such redemption.

  COVENANTS; EVENTS OF DEFAULT

     The 10 1/2% Notes Indenture contains covenants and provides for events of

9 7/8% NOTES

  GENERAL

     On May 13, 1999, RSL PLC issued the 9 7/8% Notes, or the old 9 7/8% Notes
pursuant to an indenture, dated as of May 13, 1999, or the 9 7/8% Notes
Indenture, among RSL PLC, RSL COM and The Chase Manhattan Bank, as Trustee. On
December 10, 1999, the old 9 7/8% Notes were exchanged for $175 million
principal amount at maturity of substantially identical notes that had been
registered under the Securities Act, or the 9 7/8% Notes. RSL COM has
unconditionally guaranteed the 9 7/8% Notes.

  PRINCIPAL, MATURITY AND INTEREST

     The 9 7/8% Notes are limited in aggregate principal amount at maturity to
$175 million and will mature on November 15, 2009. Interest on the 9 7/8% Notes

AMENDMENTS TO INDENTURES

     In September 1999, we amended the 1996 Indenture, the U.S. Dollar Notes
Indentures, the DM Notes Indenture, the 12% Notes Indenture, the 10 1/2% Notes
Indenture and the 9 7/8% Indenture to modify exceptions to the limitations on
issuances and sales of capital stock of certain subsidiaries to limitations on
asset dispositions contained in the Indentures to permit the issuance and sale
of capital stock of deltathree.com and our Australian subsidiary in public or
private transactions without restricting use of proceeds solely to investments
in telecommunications assets and to employees, directors and consultants
pursuant to customary equity compensation and incentive plans.

     In connection with our Dollar and Euro Notes offerings, RSL USA entered
into supplemental indentures with respect to the 1996 Indenture, U.S. Dollar
Notes Indentures, the DM Notes Indenture, the 12% Notes Indenture, the 10 1/2%
Notes Indenture and the 9 7/8% Indenture, pursuant to which RSL USA guaranteed
the obligations of RSL PLC under those indentures and the related notes. RSL
USA's guarantees will be released in the event of the release of RSL USA's
guarantee of the new notes as described in the section "Description of the New
Notes and the New Notes Guarantees" under the heading "Description of the New
Notes Guarantees."

                                       28

<PAGE>

           DESCRIPTION OF THE NEW NOTES AND THE NEW NOTES GUARANTEES

     The new dollar notes and the new euro notes will be issued under
Indentures, each dated as of February 22, 2000, or the Indentures, between RSL
PLC, RSL COM and RSL USA, as guarantors, or the Guarantors, and The Chase
Manhattan Bank, as trustee. The new dollar notes and the new euro notes are
referred to collectively in this prospectus as "the new notes." The statements
under this caption relating to the new notes and the Indentures are summaries
and do not purport to be complete, and are subject to, and are qualified in
their entirety by reference to, all the provisions of the Indenture, including
the definitions of certain terms therein. The Indentures are by their terms
subject to and governed by the Trust Indenture Act of 1939, as amended. Unless
otherwise indicated, references under this caption to sections, "ss." or
articles are references to the Indentures. Where reference is made to particular
provisions of the Indentures or to defined terms not otherwise defined herein,
such provisions or defined terms are incorporated herein by reference. The
definitions of certain capitalized terms used in the following summary are set
forth below under the heading "Certain Definitions."

GENERAL

     The new notes will be senior unsecured obligations of RSL PLC and will
mature on March 1, 2010. Interest on each new note will accrue at the rate of
12 7/8% on the principal amount thereof from the last Interest Payment Date on
which interest has been paid on the old note in exchange therefore, or, if no
interest has been paid on such old note, from February 22, 2000. Interest will
be payable semiannually in cash on March 1 and September 1 of each year,
commencing September 1, 2000, to the Book-Entry Depositary (in the case of
Global Notes) or to the Person in whose name the note (or any predecessor note)
is registered (in the case of Definitive Registered Notes) at the close of
business on the preceding February 15 and August 15, as the case may be.
Interest on the notes will be computed on the basis of a 360-day year of twelve
30-day months. (ss.ss. 301, 307 & 310). You will not receive interest on any old
notes we accept for exchange that could otherwise be payable on any Interest
Payment Date, the record date for which occurs on or after consummation of the
exchange offer for the old notes.

     The guarantee by the Guarantors of payments in respect of each of the new
dollar notes and the new euro notes or, collectively the "notes guarantees,"
will rank equal in right of payment with the Guarantors' unsecured
unsubordinated obligations.

     Principal of and premium, if any, and interest on the new notes may be
presented for registration of transfer and exchange, at the office or agency of
RSL PLC maintained for that purpose in the Borough of Manhattan, The City of New
York, provided that at the option of RSL PLC, payment of interest on the notes
may be made by check mailed to the address of the Person entitled thereto as it
appears in the related Note Register. Until otherwise designated by RSL PLC,
such office or agency will be the corporate trust office of the Trustee, as
Paying Agent and Registrar. (ss.ss. 301, 305 & 1002)

     The new notes will be issued without coupons, in denominations of $1,000 in
the case of the new dollar notes and (U)1,000 in the case of the new euro notes,
and any integral multiples of $1,000 or (U)1,000 in excess thereof. (ss. 302) No
service charge will be made for any registration of transfer or exchange of
notes, but RSL PLC may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith. (ss. 305)

     The new dollar notes are initially limited to $100,000,000 in aggregate
principal amount and the new euro notes are initially limited to (U)100,000,000
in aggregate principal amount. We may issue additional dollar notes or euro
notes (in either case "additional notes") from time to time after the date of
the Indentures, subject to the provisions of the Indentures, as well as the
provisions of our outstanding indebtedness, including the provisions restricting
additional indebtedness under the Indentures and those other obligations.

RANKING

     The new notes and the new notes guarantees will be unsecured obligations of
RSL PLC and the Guarantors, respectively, rank equal in right of payment with
all existing and future unsecured obligations of RSL PLC and the Guarantors,
respectively, and rank senior in right of payment to all future subordinated
obligations of RSL PLC and the Guarantors, respectively. Holders of secured
obligations of RSL PLC or the Guarantors, however,

                                       29

<PAGE>

will have claims that are prior to the claims of the holders of the new notes or
the new notes guarantees with respect to the assets securing such other
obligations.

     RSL PLC is a direct wholly-owned subsidiary of RSL COM. RSL COM's principal
operations are conducted through subsidiaries of RSL PLC and, therefore, RSL COM
and RSL PLC are dependent upon the cash flow of such subsidiaries to meet their
respective obligations. RSL COM's subsidiaries (other than RSL PLC and RSL USA)
have no obligation to guarantee or otherwise pay amounts due under the notes.
Therefore, the new notes are effectively subordinated to all indebtedness and
other liabilities and commitments (including trade payables) of RSL COM's
subsidiaries (other than RSL PLC and RSL USA). Any right of RSL PLC to receive
assets of any of the subsidiaries other than RSL USA upon any liquidation or
reorganization of such subsidiary (and the consequent right of holders of the
notes to participate in those assets) is effectively subordinated to the claims
of the subsidiary's creditors, except to the extent that RSL PLC is itself
recognized as a creditor of the subsidiary. Any recognized claims of RSL PLC as
a creditor of the subsidiary would be subordinate to any prior security interest
held by any other creditor of the subsidiary and obligations of the subsidiary
that are senior to those owing to RSL PLC.

     As of December 31, 1999, on a pro forma basis after giving effect to the
issuance of the old notes and RSL USA's guarantee of RSL PLC's previously issued
and outstanding notes:

     o the total amount of outstanding liabilities of the Guarantors and RSL PLC
       (excluding their subsidiaries), including trade payables, would have been
       approximately $1.6 billion; and

     o the total amount of outstanding liabilities of the subsidiaries of RSL
       COM (other than RSL PLC and RSL USA), including trade payables, would
       have been approximately $463.6 million.

BOOK-ENTRY; DELIVERY AND FORM

  GENERAL

     Each of the new dollar notes and the new euro notes will initially be
represented by one or more global securities in bearer form without interest
coupons, which will be issued in denominations equal to the outstanding
principal amount of the notes represented thereby. Each Restricted Global Note
will be deposited with the Book-Entry Depositary pursuant to the terms of a Note
Deposit Agreement, dated as of February 22, 2000 (the "Deposit Agreement"),
between RSL PLC, for the limited purposes set forth therein, and The Chase
Manhattan Bank, as book-entry depositary (the "Book-Entry Depositary").

     In the case of new dollar notes, the Book-Entry Depositary will issue a
certificateless interest for each Global Note, representing a 100% interest in
the respective underlying Global Note in the name of Cede & Co., as a nominee of
The Depository Trust Company ("DTC"). Beneficial interests in the Global Notes
representing new dollar notes will be shown on, and transfers thereof will be
effected only through, records maintained in book-entry form by DTC (with
respect to its participants) and its participants.

     In the case of euro notes, the Book-Entry Depositary will issue a
certificated depositary interest for each Global Note, representing a 100%
interest in the respective underlying Global Note, in the name of Euroclear and
Clearstream Banking, societe anonyme ("Clearstream"). Beneficial interests in
the Global Notes representing euro notes will be shown on, and transfers thereof
will be effected only through, records maintained in book-entry form by
Euroclear and Clearstream (with respect to their participants) and their
participants.

     All interests in the Global Notes representing new euro notes will be
subject to the procedures and requirements of Euroclear or Clearstream, as the
case may be.

     Beneficial interests in each Global Note are referred to herein as
"Book-Entry Interests."

                                       30

<PAGE>

DEFINITIVE REGISTERED NEW NOTES

     Under the terms of the Deposit Agreement and the Indentures, owners of
Book-Entry Interests in the Global Notes will receive definitive notes in
registered form ("Definitive Registered Notes"):

          (1) if DTC, in the case of the dollar notes, or Euroclear and
     Clearstream, in the case of the euro notes, notifies RSL PLC or the
     Book-Entry Depositary in writing that it (or its nominee) is unwilling or
     unable to continue to act as depositary or ceases to be a clearing agency
     registered under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), and, in either case, a successor depositary registered as
     a clearing agency under the Exchange Act is not appointed by RSL PLC within
     90 days,

          (2) at any time if RSL PLC determines that the Global Notes (in whole
     but not in part) should be exchanged for Definitive Registered Notes,
     provided that (x) such exchange is required by (A) any applicable law or
     (B) any event beyond RSL PLC's control or (y) payments of interest on any
     Global Note, Depositary Interest or Book-Entry Interest are, or would
     become, subject to any deduction or withholding for taxes,

          (3) at any time after the consummation of the Exchange Offer, if the
     owner of a Book-Entry Interest requests such exchange in writing delivered
     to DTC, or Euroclear and Clearstream, as applicable and through DTC, or
     Euroclear and Clearstream, as applicable to the Book-Entry Depositary and
     the Trustee or

          (4) if the Book-Entry Depositary is at any time unwilling or unable to
     continue as Book-Entry Depositary and a successor Book-Entry Depositary is
     not appointed by RSL PLC within 90 days.

     In no event will definitive securities in bearer form be issued. Any
Definitive Registered Notes will be issued in fully registered form in
denominations of $1,000 principal amount or (U)1,000 principal amount, as
applicable, and integral multiples thereof. Any Definitive Registered Notes will
be registered in such name or names as DTC, or Euroclear and Clearstream, as
applicable, shall instruct the Trustee, through the Book-Entry Depositary. It is
expected that the instructions will be based upon directions received by DTC, or
Euroclear and Clearstream, as applicable, from the participants reflecting the
beneficial ownership of Book-Entry Interests. To the extent permitted by law,
RSL PLC, the Trustee and any paying agent shall be entitled to treat the person
in whose name any Definitive Registered Note is registered as the absolute owner
thereof. While any Global Note is outstanding, holders of Definitive Registered
Notes may exchange their Definitive Registered Notes for a corresponding
Book-Entry Interest in such Global Note by surrendering their Definitive
Registered Notes to the Book-Entry Depositary and providing the certificates and
opinions required by the Indentures. The Book-Entry Depositary will make the
appropriate adjustments to the Global Note underlying such Book-Entry Interest
to reflect any issue or surrender of Definitive Registered Notes. The Indentures
contain provisions relating to the maintenance by a registrar of a register
reflecting ownership of Definitive Registered Notes, if any, and other
provisions customary for a registered debt security. Payment of principal and
interest on each Definitive Registered Note will be made to the holder appearing
on the register at the close of business on the record date at his address shown
on the register on the record date.

     U.S. HOLDERS SHOULD BE AWARE THAT, UNDER CURRENT U.K. LAW, UPON THE
ISSUANCE TO A HOLDER OF DEFINITIVE REGISTERED NOTES, SUCH HOLDER WILL BECOME
SUBJECT TO U.K. INCOME TAX (CURRENTLY 20%) TO BE WITHHELD ON ANY PAYMENTS OF
INTEREST ON THE DEFINITIVE REGISTERED NOTES AS SET FORTH UNDER THE SECTION
"CERTAIN UNITED KINGDOM TAX CONSIDERATIONS FOR U.S. HOLDERS OF NOTES." SEE BELOW
UNDER THE HEADING "ADDITIONAL AMOUNTS." A U.S. HOLDER OF DEFINITIVE REGISTERED
NOTES WILL NOT, UNLESS THERE HAS BEEN A CHANGE IN LAW OR A "LISTING FAILURE" (AS
DEFINED HEREIN) AND CERTAIN OTHER CONDITIONS ARE MET, BE ENTITLED TO RECEIVE
ADDITIONAL AMOUNTS WITH RESPECT TO SUCH DEFINITIVE REGISTERED NOTES. HOWEVER, A
U.S. HOLDER OF DEFINITIVE REGISTERED NOTES MAY BE ENTITLED TO RECEIVE A REFUND
OF WITHHELD AMOUNTS FROM THE INLAND REVENUE IN CERTAIN CIRCUMSTANCES.

DESCRIPTION OF BOOK-ENTRY SYSTEMS

     Upon receipt of the Global Notes, the Book-Entry Depositary will issue a
certificateless interest (in the case of the new dollar notes) or a certificated
depositary interest (in the case of the new euro notes) for each such Global
Note, representing a 100% interest in the respective underlying Global Note, in
the name of DTC's nominee (in the case of the new dollar notes) or in the name
of the common depositary for Euroclear and

                                       31

<PAGE>

Clearstream (in the case of new euro notes). Ownership of Book-Entry Interests
will be limited to persons who have accounts with DTC, including Euroclear and
Clearstream ("participants"), or persons who have accounts through participants
("indirect participants"). Upon such issuance of interests in such Global Notes,
DTC, Euroclear or Clearstream, as applicable, will credit, on its internal
book-entry registration and transfer system, its participants' accounts with the
respective interests owned by such participants. Such accounts initially will be
designated by or on behalf of the initial purchasers. Ownership of Book-Entry
Interests will be shown on, and the transfer of such ownership will be effected
only through, records maintained by DTC, Euroclear or Clearstream, as
applicable, or its nominee (with respect to interests of participants) and the
records of participants (with respect to interests of indirect participants).

     The laws of some countries and some states in the United States may require
that certain purchasers of securities take physical delivery of such securities
in definitive form. Such limits and such laws may impair the ability to own,
transfer or pledge the Book-Entry Interests in the Global Notes.

     So long as the Book-Entry Depositary, or its nominee, is the holder of the
Global Notes, the Book-Entry Depositary or such nominee, as the case may be,
will be considered the sole holder of such Global Notes for all purchases under
the Indentures and the notes. Except as set forth above, participants or
indirect participants will not be entitled to have notes or Book-Entry Interests
registered in their names, will not receive or be entitled to receive physical
delivery of notes or Book-Entry Interests in definitive bearer or registered
form and will not be considered the owners or holders thereof under the
Indentures. Accordingly, each person owning a Book-Entry Interest must rely on
the procedures of the Book-Entry Depositary and DTC, Euroclear and Clearstream
and, if such person is an indirect participant in DTC, the procedures of the
participants through which such person owns its interest, to exercise any rights
and remedies of a holder under the Indentures. If any definitive notes are
issued to participants or indirect participants, they will be issued in
registered form, as described above. Unless and until Book-Entry Interests are
exchanged for Definitive Registered Notes, the certificateless interest held by
DTC and the certificated depositary interest held by the common depositary may
not be transferred except as a whole between DTC (in the case of the dollar
notes) or Euroclear and Clearstream (in the case of the euro notes) and a
nominee between nominees of each of them or any such nominee to a successor of
DTC or Euroclear and Clearstream, as applicable, or a successor of such nominee.

PAYMENTS ON THE GLOBAL NOTES

     Payments of any amounts owing in respect of the Global Notes will be made
through one or more paying agents appointed under the Indentures (which
initially will include The Chase Manhattan Bank in New York and The Chase
Manhattan Bank in London, as paying agent for the notes) to the Book-Entry
Depositary as the holder of the Global Notes. All such amounts will be payable
in U.S. dollars in the case of the new dollar notes, and in euros in the case of
the new euro notes. Upon receipt of any such amounts in respect of the Global
Notes, the Book-Entry Depositary will pay such amounts to DTC, Euroclear or
Clearstream in proportion to its respective interests, as shown on the
Book-Entry Depositary's records.

     RSL PLC expects that DTC or Euroclear or Clearstream, as applicable or a
nominee, upon receipt of any payment made in respect of the Global Notes, will
credit its participants' accounts with such payments in amounts proportionate to
their respective interest in the principal amount of such Global Note as shown
on the records of DTC or Euroclear or Clearstream, as applicable, or its
nominee. RSL PLC expects that payments by participants to owners of Book-Entry
Interests held through such participants will be governed by standing customer
instructions and customary practices, as is now the case with the securities
held for the account of customers in bearer form or registered in "street name,"
and will be the responsibility of such participants. Distribution with respect
to ownership of Book-Entry Interests held through Euroclear or Clearstream will
be credited to the cash accounts of Euroclear participants or Clearstream
participants in accordance with the relevant system's rules and procedures, to
the extent received by its depositary.

     None of RSL PLC, the Book-Entry Depositary or any paying agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of Book-Entry Interests or for maintaining, supervising
or reviewing all records relating to such Book-Entry Interests or beneficial
ownership interests.

                                       32

<PAGE>

REDEMPTION OF GLOBAL NOTES

     In the event any Global Note (or any portion thereof) is redeemed, the
Book-Entry Depositary will, through DTC, Euroclear or Clearstream, as
applicable, redeem, from the amount received by it in respect of the redemption
of such Global Note, an equal amount of the Book-Entry Interests in such Global
Note. The redemption price payable in connection with the redemption of such
Book-Entry Interest will be equal to the amount received by the Book-Entry
Depositary in connection with the redemption of such Global Note (or any portion
thereof). RSL PLC understands that under existing DTC, Euroclear and Clearstream
practices, if fewer than all of the notes are to be redeemed at any time, DTC,
Euroclear or Cedelbank, as applicable, will credit participants' accounts on a
proportionate basis (with adjustments to prevent fractions) or by lot or on such
other basis as DTC, Euroclear or Clearstream, as applicable, deems fair and
appropriate; provided that no beneficial interests of less than $1,000 principal
amount (in the case of the new dollar notes) or (U)1,000 (in the case of the new
euro notes) may be redeemed in part.

TRANSFERS

     Pursuant to the Deposit Agreement, the Global Notes may be transferred only
to the successor to the Book-Entry Depositary.

     All transfers of Book-Entry Interests between participants in DTC,
Euroclear or Clearstream, as applicable, will be effected by DTC, Euroclear or
Clearstream, as applicable, pursuant to customary procedures established by such
entity and its participants.

ACTION BY OWNERS OF BOOK-ENTRY INTERESTS

     As soon as practicable after receipt by the Book-Entry Depositary of notice
of any solicitation of consents or request for a waiver of other action by the
holders of notes, or of any offer to purchase the notes with Excess Proceeds or
upon a Change of Control (as defined under the headings "Change of Control" and
"Certain Definitions," respectively), the Book-Entry Depositary will mail to
DTC, Euroclear and Clearstream a notice containing (a) such information as is
contained in the notice received by the Book-Entry Depositary, (b) a statement
that at the close of business on a specified record date DTC, Euroclear and
Clearstream will be entitled to instruct the Book-Entry Depositary as to the
consent, waiver or other action, if any, pertaining to such notes and (c) a
statement as to the manner in which such instructions may be given. In addition,
the Book-Entry Depositary will forward to DTC, Euroclear or Clearstream, as
applicable, all materials pertaining to any such solicitation, request, offer or
other action. Upon the written request of DTC, Euroclear or Clearstream, as
applicable, the Book-Entry Depositary shall endeavor insofar as practicable to
take such action regarding the requested consent, waiver, offer or other action
in respect of such notes in accordance with any instructions set forth in such
request. DTC, Euroclear and Clearstream may grant proxies or otherwise authorize
their respective participants or indirect participants to provide such
instructions to the Book-Entry Depositary so that they may exercise any rights
of a holder or take any other actions which a holder is entitled to take under
the Indentures. Under its usual procedures, DTC would mail an omnibus proxy to
RSL PLC and the Book-Entry Depositary assigning Euroclear's and Clearstream's
consenting or voting rights to those DTC participants to whose accounts such
Book-Entry Interests are credited on a record date as soon as possible after
such record date. Euroclear or Clearstream, as the case may be, will take any
action permitted to be taken by a holder under the Indentures on behalf of a
Euroclear participant or Clearstream participant only in accordance with its
relevant rules and procedures and subject to its depositary's ability to effect
such actions on its behalf. The Book-Entry Depositary will not exercise any
discretion in the granting of consents or waivers or the taking of any other
action relating to the Indentures.

     DTC has advised RSL PLC that it will take any action permitted to be taken
by a holder of notes (including the presentation of notes for exchange as
described above) only at the direction of one or more participants to whose
account the DTC interests in the Global Notes are credited and only in respect
of such portion of the aggregate principal amount of notes, as to which such
participant or participants has or have given such direction.

REPORTS

     The Book-Entry Depositary will immediately send to DTC, Euroclear or
Clearstream, as applicable, a copy of any notices, reports and other
communications received relating to RSL PLC, the notes or the Book-Entry
Interests.

ACTION BY BOOK-ENTRY DEPOSITARY

     Upon the occurrence of a Default with respect to the new notes, or in
connection with any other right of the holder of a Global Note under the
Indentures, if requested in writing by DTC, Euroclear or Clearstream, as
applicable, the Book-Entry Depositary will take any such action as shall be
requested in such notice; provided that the Book-Entry Depositary has been
offered reasonable security or indemnity against the costs, expenses and
liabilities that might be incurred by it in compliance with such request by the
owners of Book-Entry Interests.

RESIGNATION OF BOOK-ENTRY DEPOSITARY

     The Book-Entry Depositary may at any time resign as Book-Entry Depositary
by written notice to RSL PLC and DTC, Euroclear or Clearstream, as applicable,
such resignation to become effective upon the appointment of a successor book
entry depositary, in which case the Global Notes shall be delivered to that
successor. If no such successor has been so appointed by RSL PLC within
90 days, the Book-Entry Depositary may request RSL PLC to issue Definitive
Registered Notes as described above.

     If at any time DTC is unwilling or unable to continue as a depositary for
the Book-Entry Interests for the dollar notes and a successor depositary is not
appointed by RSL PLC within 90 days, DTC may request that RSL PLC issue
Definitive Registered Notes in exchange therefor.

EXPENSES OF BOOK-ENTRY DEPOSITARY

     RSL PLC has agreed to indemnify the Book-Entry Depositary against certain
liabilities incurred by it and pay the charges of the Book-Entry Depositary as
agreed between RSL PLC and the Book-Entry Depositary.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     The Deposit Agreement may be amended by RSL PLC and the Book-Entry
Depositary without notice to or consent of DTC, Euroclear or Clearstream or any
owner of a Book-Entry Interest: (a) to cure any ambiguity, defect or
inconsistency, provided that such amendment or supplement does not adversely
affect the rights of DTC or Euroclear or Clearstream, as applicable, or any
holder of Book-Entry Interests, (b) to evidence the succession of another person
to RSL PLC (when a similar amendment with respect to the Indentures is being
executed) and the assumption by any such successor of the covenants of RSL PLC
therein, (c) to evidence or provide for a successor Book-Entry Depositary, (d)
to make any amendment, change or supplement that does not adversely affect DTC
or Euroclear or Clearstream, as applicable, or any owner of Book-Entry
Interests, (e) to add to the covenants of RSL PLC or the Book-Entry Depositary,
(f) to add a guarantor when a guarantor is made a party to the Indentures
pursuant to the Indentures or (g) to comply with the United States federal and
U.K. securities laws. Except as provided in the Deposit Agreement, no amendment
that adversely affects DTC or Euroclear or Clearstream, as applicable, may be
made to the Deposit Agreement without the consent of DTC or Euroclear or
Clearstream, as applicable, and no amendment that adversely affects the holders
of Book-Entry Interests may be made without the consent of a majority of the
aggregate principal amount of Book-Entry Interests outstanding. Upon the
issuance of Definitive Registered Notes in exchange for Book-Entry Interests
constituting the entire principal amount of notes, the Deposit Agreement will
terminate. The Deposit Agreement may be terminated upon the resignation of the
Book-Entry Depositary if no successor has been appointed within 90 days as set
forth above.

INFORMATION CONCERNING DTC, EUROCLEAR AND CLEARSTREAM

     RSL PLC understands as follows with respect to DTC, Euroclear and
Clearstream:

     DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a

                                       34

<PAGE>

"clearing corporation" within the meaning of the New York Uniform Commercial
Code, and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Securities Exchange Act of 1934, as amended. DTC was created
to hold securities of its participants and to facilitate the clearance and
settlement of transactions among its participants in such securities through
electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. DTC
participants include securities brokers and dealers (including the initial
purchasers), banks, trust companies, clearing corporations and certain other
organizations, some of whom (and/or their representatives) own DTC. Access to
the DTC book-entry system is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

     Because DTC can only act on behalf of participants, who in turn act on
behalf of indirect participants and certain banks, the ability of an owner of a
Book-Entry Interest to pledge such interest to persons or entities that do not
participate in the DTC system, or otherwise take actions in respect of such
interest, may be limited by the lack of a definitive certificate for such
interest. The laws of some states require that certain persons take physical
delivery of securities in definitive form. Consequently, the ability to transfer
Book-Entry Interests to such persons may be limited. In addition, beneficial
owners of Book-Entry Interests through the DTC system will receive distributions
attributable to the Global Notes only through DTC participants.

     Euroclear and Clearstream hold securities for participating organizations
and facilitate the clearance and settlement of securities transactions between
their respective participants through electronic book-entry changes in accounts
of such participants. Euroclear and Clearstream provide to their participants,
among other things, services for safekeeping, administration, clearance and
settlement of internationally traded securities and securities lending and
borrowing. Euroclear and Clearstream interface with some domestic securities
markets. Euroclear and Clearstream participants are mainly financial
institutions such as underwriters, securities brokers and dealers, banks, trust
companies and certain other organizations. Indirect access to Euroclear or
Clearstream is also available to others such as banks, brokers, dealers and
trust companies that clear through or maintain a custodian relationship with a
Euroclear or Clearstream participant, either directly or indirectly.

GLOBAL CLEARANCE AND SETTLEMENT UNDER BOOK-ENTRY SYSTEM

     Initial Settlement.  Investors that own their Book-Entry Interest through
DTC (other than through accounts at Euroclear or Clearstream) will follow the
settlement practices applicable to U.S. corporate debt obligations. The
securities custody accounts of investors will be credited with their holdings
against payment in same-day funds on the settlement date.

     Investors that own their Book-Entry Interests through Euroclear or
Clearstream accounts will follow the settlement procedures applicable to
conventional eurobonds in registered form. Book-Entry Interests will be credited
to the securities custody accounts of Euroclear and Clearstream holders on the
business day following the settlement date against payment for value on the
settlement date.

     Secondary Market Trading.  Secondary market trading activity in such
Book-Entry Interests will settle in same-day funds.

     Since the purchasers determine the place of delivery, it is important to
establish at the time of trading of any initial Book-Entry Interests where both
the purchaser's and seller's accounts are located to ensure that settlement can
be made on the desired value date.

OPTIONAL REDEMPTION

     The new notes are subject to redemption, at the option of RSL PLC, in whole
or in part, at any time on or after March 1, 2005 and prior to maturity, upon
not less than 30 nor more than 60 days' notice mailed to each holder of notes to
be redeemed at such holder's address appearing in the note register, in
principal amounts of $1,000 or (U)1,000, as the case may be, or an integral
multiple of $1,000 or (U)1,000, at the following redemption prices (expressed as
percentages of the principal amount thereof) plus accrued interest to but
excluding the

(ss.ss. 203, 1101, 1105 & 1107)

     In addition, at any time prior to March 1, 2003, in the event that RSL COM
receives net cash proceeds from the public or private sale of its Common Stock,
RSL PLC (to the extent it receives such proceeds) may, at its option, apply an
amount equal to any such net cash proceeds or any portion thereof to redeem,
from time to time, new dollar notes or new euro notes in a principal amount of
up to an aggregate amount equal to 33 1/3% of the original aggregate principal
amount of each of the new dollar notes and the new euro notes, as applicable
(including any additional notes issued after the closing date) provided,
however, that at least 66 2/3% of the aggregate original principal amount at
maturity of each of the new dollar notes and the new euro notes, as applicable
(including any additional notes issued after the closing date) remain
outstanding after each redemption. Each redemption must occur on a Redemption
Date within 180 days of the related sale and upon not less than 30 nor more than
60 days' notice mailed to each holder of notes to be redeemed at such holder's
address appearing in the Note Register, in amounts of $1,000 or (U)1,000, as the
case may be, or an integral multiple of $1,000 or (U)1,000 at redemption prices
equal to 112.875% and 112.875% of the principal amount of the dollar and the
euro notes redeemed, respectively, plus accrued interest to but excluding the
Redemption Date.

     If less than all the notes are to be redeemed, the Trustee shall select, in
such manner as it shall deem fair and appropriate, the particular notes to be
redeemed or any portion thereof that is an integral multiple of $1,000 or
(U)1,000, as the case may be. (ss.1104)

     In the event that (1) the Guarantors or RSL PLC has become or would become
obligated to pay any Additional Amounts (as defined herein) as a result of
(x) certain changes in or affecting withholding tax laws or (y) a Listing
Failure (as defined herein) provided that RSL PLC has used reasonable best
efforts to list and maintain a listing of the notes on a "recognized stock
exchange" (within the meaning of Section 841 of the U.K. Income and Corporation
Taxes Act 1988), and (2) the Guarantors and RSL PLC are unable to avoid the
requirement to pay such Additional Amounts by taking reasonable measures
available to them (including, without limitation, the Guarantors making payments
directly to holders under the notes guarantees, unless such payment is likely to
result in adverse consequences to RSL PLC or the Guarantors), then RSL PLC may
redeem all, but not less than all, of the dollar notes or the euro notes or
both, as applicable at any time, at 100% of the principal amount thereof on the
redemption date, together with accrued interest thereon, if any, to but
excluding the redemption date.

     Prior to the publication of the notice of redemption in accordance with the
foregoing, RSL PLC shall deliver to the Trustee an officer's certificate stating
that RSL PLC is entitled to effect such redemption based on a written opinion of
independent tax counsel or accounting firm reasonably satisfactory to the
Trustee. See the heading "Additional Amounts."

     The new notes do not have the benefit of any sinking fund.

COVENANTS

     Each Indenture contains, among others, the following covenants:

  LIMITATION ON CONSOLIDATED DEBT

     RSL COM may not, and may not permit any Restricted Subsidiary to, incur any
Debt unless the ratio of (a) the aggregate consolidated principal amount of Debt
(which is defined in the Indentures to include the accreted value of any Debt
issued at a discount) of RSL COM outstanding as of the most recent available
quarterly or annual balance sheet, after giving pro forma effect to the
Incurrence of such Debt and any other Debt Incurred since such balance sheet
date and the receipt and application of the proceeds thereof, to (b) four (4)
times the Consolidated Cash Flow Available for Fixed Charges for the most recent
fiscal quarter next preceding the Incurrence of such Debt for which consolidated
financial statements are available, determined on a pro forma basis as if any
such Debt had been Incurred and the proceeds thereof had been applied at the
beginning of such recent fiscal quarter, would be less than 7.0 to 1.0 for such
period.

     Notwithstanding the foregoing limitation, RSL COM and any Restricted
Subsidiary may Incur the following:

          (1) Debt under Credit Facilities in an aggregate principal amount at
     any one time not to exceed $200 million, and any renewal, extension,
     refinancing or refunding thereof in an amount which, together with any
     principal amount remaining outstanding under all Credit Facilities, does
     not exceed the aggregate principal amount outstanding under all Credit
     Facilities immediately prior to such renewal, extension, refinancing or
     refunding;

          (2) Debt owed by RSL COM to any Restricted Subsidiary or Debt owed by
     a Restricted Subsidiary to RSL COM or a Restricted Subsidiary; provided,
     however, that upon either (x) the transfer or other disposition by such
     Restricted Subsidiary or RSL COM of any Debt so permitted to a Person other
     than RSL COM or another Restricted Subsidiary or (y) such Restricted
     Subsidiary ceasing to be a Restricted Subsidiary, the provisions of this
     clause (2) shall no longer be applicable to such Debt and such Debt shall
     be deemed to have been Incurred at the time of such transfer or other
     disposition;

          (3) Debt Incurred to renew, extend, refinance or refund (each, a
     "refinancing") (x) Debt outstanding at the date of the Indentures or
     (y) Incurred pursuant to the first paragraph of this "Limitation on
     Consolidated Debt," or clause (6) or (8) of this paragraph or (z) the notes
     originally issued on the date of the Indentures or notes exchanged
     therefore, in each case, in an aggregate principal amount not to exceed the
     aggregate principal amount of and accrued interest on the Debt so
     refinanced plus the amount of any premium required to be paid in connection
     with such refinancing pursuant to the terms of the Debt so refinanced or
     the amount of any premium reasonably determined by RSL COM as necessary to
     accomplish such refinancing by means of a tender offer or privately
     negotiated repurchase, plus the expenses of RSL COM or the Restricted
     Subsidiary effecting such refinancing incurred in connection with such
     refinancing; provided, however, that Debt the proceeds of which are used to
     refinance the new notes or Debt which is equal in right of payment to the
     new notes and the new notes guarantees or Debt which is subordinate in
     right of payment to the new notes and the new notes guarantees, shall only
     be permitted if (A) in the case of any refinancing of the new notes or Debt
     which is equal in right of payment to the new notes and the new notes
     guarantees, the refinancing Debt is made equal in right of payment or
     subordinated to the new notes and the new notes guarantees and, in the case
     of any refinancing of Subordinated Debt, the refinancing Debt constitutes
     Subordinated Debt and (B) in any case, the refinancing Debt by its terms,
     or by the terms of any agreement or instrument pursuant to which such Debt
     is issued, does not have a final stated maturity prior to the final stated
     maturity of the Debt being refinanced, and the Average Life of such new
     Debt is at least equal to the remaining Average Life of the Debt being
     refinanced (assuming that such Debt being refinanced had a final stated
     maturity three months later than its actual final stated maturity);

          (4) Debt in an aggregate principal amount not in excess of (A) two
     (2) times the aggregate amount of RSL COM's Incremental Paid-in Capital
     minus (B) $165 million;

                                       37

<PAGE>

          (5) Debt in an aggregate principal amount not in excess of 80% of the
     aggregate amount of accounts receivable set forth on the most recent
     unaudited quarterly or audited annual financial statements of RSL COM and
     its consolidated subsidiaries filed with the Commission;

          (6) Purchase Money Debt, which is incurred for the construction,
     acquisition or improvement of Telecommunications Assets, provided that the
     amount of such Purchase Money Debt does not exceed the cost of the
     construction, acquisition or improvement of the applicable
     Telecommunications Assets;

          (7) Debt consisting of Permitted Interest Rate and Currency Protection
     Agreements; and

          (8) Debt not otherwise permitted to be Incurred pursuant to clauses
     (1) through (7) above, which, together with any other outstanding Debt
     Incurred pursuant to this clause (8), has an aggregate principal amount not
     in excess of $50 million at any time outstanding.

     For purposes of determining compliance with this "Limitation on
Consolidated Debt" covenant, with respect to any item of Debt (x) in the event
that an item of Debt meets the criteria of more than one of the types of Debt
RSL COM or a Restricted Subsidiary is permitted to Incur pursuant to the
foregoing clauses (1) through (8), RSL COM shall have the right, in its sole
discretion, to classify such item of Debt and shall only be required to include
the amount and type of such Debt under the clause permitting the Debt as so
classified and (y) any other obligation of the obligor on such Debt (or of any
other Person who could have Incurred such Debt under this covenant) arising
under any Guarantee, Lien or letter of credit supporting such Debt shall be
disregarded to the extent that such Guarantee, Lien or letter of credit secures
the principal amount of such Debt.

     For purposes of determining compliance with the foregoing restriction on
the Incurrence of Debt with respect to Debt denominated in a foreign currency,
the dollar-equivalent principal amount of such foreign-currency-denominated Debt
shall be calculated based on the relevant currency exchange rate in effect on
the date that such foreign-currency-denominated Debt was Incurred, in the case
of term debt, or first committed, in the case of revolving credit debt, provided
that (x) the dollar-equivalent principal amount of any such Debt outstanding on
the Closing Date shall be calculated based on the relevant currency exchange
rate in effect on the Closing Date and (y) if such Debt is Incurred to refinance
other Debt denominated in a foreign currency, and such refinancing would cause
the applicable dollar-denominated restriction to be exceeded if calculated at
the relevant currency exchange rate in effect on the date of such refinancing,
such dollar-denominated restriction shall be deemed not to have been exceeded so
long as the principal amount of such refinancing Debt does not exceed the
principal amount of such Debt being refinanced. The principal amount of any Debt
Incurred to refinance other Debt, if Incurred in a different currency from the
Debt being refinanced, shall be calculated based on the currency exchange rate
applicable to the currencies in which such respective Debt is denominated that
is in effect on the date of such refinancing.

  LIMITATION ON RESTRICTED PAYMENTS

     RSL COM:

          (A) may not, and will not permit any Restricted Subsidiary, directly
     or indirectly, to declare or pay any dividend, or make any distribution, in
     respect of its Capital Stock or to the holders thereof, excluding (x) any
     dividends or distributions payable solely in shares of its Capital Stock
     (other than Disqualified Stock) or in options, warrants or other rights to
     acquire its Capital Stock (other than Disqualified Stock), (y) any
     dividends paid to RSL COM or a Restricted Subsidiary or (z) pro rata
     dividends paid on shares of Common Stock of Restricted Subsidiaries;

          (B) may not, and may not permit any Restricted Subsidiary to,
     purchase, redeem, or otherwise retire or acquire for value (x) any Capital
     Stock of RSL COM or any Related Person of RSL COM (other than a permitted
     refinancing) or (y) any options, warrants or rights to purchase or acquire
     shares of Capital Stock of RSL COM or any Related Person of RSL COM or any
     securities convertible or exchangeable into shares of Capital Stock of RSL
     COM or any Related Person of RSL COM (other than a permitted refinancing);

          (C) may not make, or permit any Restricted Subsidiary to make, any
     Investment, except for Permitted Investments; and

                                       38

<PAGE>

          (D) may not, and may not permit any Restricted Subsidiary to, redeem,
     defease, repurchase, retire or otherwise acquire or retire for value, prior
     to any scheduled maturity, repayment or sinking fund payment, Debt of the
     Guarantors or RSL PLC which is subordinate in right of payment to the notes
     or the notes guarantees (each of clauses (A) through (D) being a
     "Restricted Payment")

     if:

          (1) an Event of Default, or an event that with the passing of time or
     the giving of notice, or both, would constitute an Event of Default, shall
     have occurred and be continuing; or

          (2) except with respect to Investments, upon giving effect to such
     Restricted Payment, RSL COM could not Incur at least $1.00 of additional
     Debt pursuant to the terms of the Indentures described in the first
     paragraph of "Limitation on Consolidated Debt" above; or

          (3) upon giving effect to such Restricted Payment, the aggregate of
     all Restricted Payments from the date of the Indentures exceeds the sum of:

             (a) (x) Consolidated Cash Flow Available for Fixed Charges since
        the end of the last full fiscal quarter prior to the date of the
        Indentures through the last day of the last full fiscal quarter ending
        immediately preceding the date of such Restricted Payment (the
        "Calculation Period") minus (y) 1.5 times Consolidated Interest Expense
        for the Calculation Period plus

             (b) an amount equal to the net reduction in Investments (other than
        reductions in Permitted Investments) in any Person resulting from
        payments of interest on Debt, dividends, repayments of loans or
        advances, or other transfers of assets, in each case to RSL COM or any
        Restricted Subsidiary or from the Net Cash Proceeds from the sale of any
        such Investment (except, in each case, to the extent any such payment or
        proceeds are included in the calculation of Consolidated Cash Flow
        Available for Fixed Charges for the Calculation Period, or from
        redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
        (valued in each case as provided in the definition of "Investments"),
        not to exceed, in each case, the amount of Investments previously made
        by RSL COM or any Restricted Subsidiary in such Person or Unrestricted
        Subsidiary plus

             (c) an amount equal to the aggregate net proceeds received after
        the date of the Indentures, including the fair market value of property
        other than cash (determined in good faith by the Board of Directors as
        evidenced by a resolution of the Board of Directors filed with the
        Trustee), as capital contributions to RSL COM or from the issuance
        (other than to a Subsidiary) of Capital Stock (other than Disqualified
        Stock) of RSL COM and warrants, rights or options on Capital Stock
        (other than Disqualified Stock) of RSL COM and the principal amount of
        Debt of RSL COM or any Restricted Subsidiary that has been converted
        into Capital Stock (other than Disqualified Stock and other than by a
        Subsidiary) of RSL COM after the date of the Indentures plus

             (d) $30 million.

     Notwithstanding the foregoing:

          (1) RSL COM may pay any dividend on Capital Stock of any class of RSL
     COM within 60 days after the declaration thereof if, on the date when the
     dividend was declared, RSL COM could have paid such dividend in accordance
     with the foregoing provisions;

          (2) RSL COM may make acquisitions of a minority equity interest in
     entities engaged in the Telecommunications Business; provided that

             (a) the acquisition of a majority equity interest in such entities
        is not then permitted or practicable under applicable law without
        regulatory consent or change of law,

             (b) the Board of Directors of RSL COM determines in good faith that
        there is a substantial probability that such approval or change of law
        will be obtained,

             (c) RSL COM or one of its Restricted Subsidiaries has the right to
        acquire Capital Stock representing a majority of the voting power of the
        Voting Stock of such entity upon receipt of

                                       39

<PAGE>

        regulatory consent or change of law and does acquire such Voting Stock
        reasonably promptly upon receipt of such consent or change of law, and

             (d) in the event that such consent or change of law has not been
        obtained within 18 months of funding such Investment, RSL COM or one of
        its Restricted Subsidiaries has the right to sell such minority equity
        interest to the Person from whom it acquired such interest, for
        consideration consisting of the consideration originally paid by RSL COM
        and its Restricted Subsidiaries for such minority equity interest;

          (3) RSL COM may repurchase any shares of its Common Stock or options
     to acquire its Common Stock from Persons who were formerly directors,
     officers or employees of RSL COM or any of its Subsidiaries, provided that
     the aggregate amount of all such repurchases made pursuant to this clause
     (3) shall not exceed $6 million, plus the aggregate cash proceeds received
     by RSL COM since the date of the Indentures from issuances of its Common
     Stock or options to acquire its Common Stock to directors, officers and
     employees of RSL COM or any of its Restricted Subsidiaries;

          (4) RSL COM or a Restricted Subsidiary may redeem, defease,
     repurchase, retire or otherwise acquire or retire for value Debt of the
     Guarantors or RSL PLC which is subordinated in right of payment to the
     notes or the notes guarantees, as the case may be, in exchange for, or out
     of the proceeds of a substantially concurrent sale (other than to a
     Subsidiary) of, Capital Stock (other than Disqualified Stock of RSL COM) or
     in a refinancing that satisfies the requirements of clause (3) of the
     second paragraph under "Limitation on Consolidated Debt";

          (5) RSL COM and its Restricted Subsidiaries may retire or repurchase
     any Capital Stock of RSL COM or of any Subsidiary of RSL COM in exchange
     for, or out of the proceeds of the substantially concurrent sale (other
     than to a Subsidiary of RSL COM) of, Capital Stock (other than Disqualified
     Stock) of RSL COM or such Restricted Subsidiary; and

          (6) RSL COM or a Restricted Subsidiary may make payments or
     distributions to dissenting stockholders pursuant to applicable law or
     pursuant to or in connection with a transaction governed by the provisions
     described below under "Mergers, Consolidations and Certain Sales of
     Assets," provided that the number of shares as to which dissent or
     appraisal rights are exercised and such payments or distributions are being
     made does not exceed 1% of the total number of shares of all classes for
     which such rights are exercisable.

  LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
  SUBSIDIARIES

     RSL COM may not, and may not permit any Restricted Subsidiary to, directly
or indirectly, create or otherwise cause or suffer to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary:

          (1) to pay dividends (in cash or otherwise) or make any other
     distributions in respect of its Capital Stock owned by RSL COM or any
     Restricted Subsidiary or pay any Debt or other obligation owed to RSL COM
     or any Restricted Subsidiary;

          (2) to make loans or advances to RSL COM or any Restricted Subsidiary;
     or

          (3) to transfer any of its property or assets to RSL COM or any
     Restricted Subsidiary.

     Notwithstanding the foregoing, RSL COM may, and may permit any Restricted
Subsidiary to, suffer to exist any such encumbrance or restriction:

          (a) pursuant to any agreement in effect on the date of the Indentures;

          (b) pursuant to an agreement relating to any Acquired Debt, which
     encumbrance or restriction is not applicable to any Person, or the
     properties or assets of any Person, other than the Person so acquired and
     was not Incurred in anticipation of such Person being acquired;

          (c) pursuant to an agreement effecting a renewal, refunding or
     extension of Debt Incurred pursuant to an agreement referred to in clause
     (a) or (b) above, provided, however, that the provisions contained in such

                                       40

<PAGE>

     renewal, refunding or extension agreement relating to such encumbrance or
     restriction are no more restrictive in any material respect than the
     provisions contained in the agreement the subject thereof;

          (d) in the case of clause (3) above, contained in any security
     agreement (including a Capital Lease Obligation) securing Debt of RSL COM
     or a Restricted Subsidiary otherwise permitted under the Indentures, but
     only to the extent such restrictions restrict the transfer of the property
     subject to such security agreement;

          (e) in the case of clause (3) above, with respect to customary
     nonassignment provisions entered into in the ordinary course of business in
     leases and other agreements;

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

             (x) the consummation of such transaction would not result in an
        Event of Default or an event that, with the passing of time or the
        giving of notice or both, would constitute an Event of Default,

             (y) such restriction terminates if such transaction is not
        consummated and

             (z) the consummation or abandonment of such transaction occurs
        within one year of the date such agreement was entered into;

          (g) pursuant to applicable law or required by any regulatory authority
     having jurisdiction over RSL COM or any Restricted Subsidiary;

          (h) pursuant to the Indentures and the new notes;

          (i) constituting a Lien otherwise permitted pursuant to "Limitations
     on Liens"; and

          (j) other encumbrances or restrictions that are not materially more
     restrictive than customary provisions in comparable financings provided
     that RSL PLC and the Guarantors provide an Officer's Certificate to the
     Trustee to the effect that in the opinion of the signers of such
     certificate such encumbrances or restrictions will not materially impact
     RSL PLC's and Guarantors' ability to make scheduled payments of interest
     and principal under the notes.

  LIMITATION ON ISSUANCE OF GUARANTEES OF DEBT BY RESTRICTED SUBSIDIARIES

     RSL COM will not permit any Restricted Subsidiary, directly or indirectly,
to incur any Guarantee of any Debt of the Guarantors or RSL PLC (other than the
notes) unless such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture providing for a Guarantee by such Subsidiary of the new
notes; any Subsidiary Guarantee by such Subsidiary of the new notes (x) will be
senior in right of payment to any Guarantee of Subordinated Debt of the
Guarantors or RSL PLC and (y) will be equal with or senior to any Guarantee of
any other Debt of the Guarantors or RSL PLC.

     Notwithstanding the foregoing, any Subsidiary Guarantee may provide by its
terms that it shall be automatically and unconditionally released and discharged
upon:

          (1) any sale, exchange or transfer, to any Person not an Affiliate of
     RSL COM, of all of RSL COM'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 not prohibited by the Indentures); or

          (2) 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.

  LIMITATION ON LIENS

     RSL COM may not, and may not permit any Restricted Subsidiary to, Incur or
suffer to exist any Lien on or with respect to any property or assets now owned
or hereafter acquired to secure any Debt without making, or causing such
Restricted Subsidiary to make, effective provision for securing the notes (x)
equally and ratably with such Debt as to such property for so long as such Debt
will be so secured or (y) in the event such Debt is

                                       41

<PAGE>

Debt of either Guarantor which is subordinate in right of payment to the notes,
prior to such Debt as to such property for so long as such Debt will be so
secured.

     The foregoing restrictions shall not apply to:

          (1) Liens existing on the date of the Indentures and securing Debt
     outstanding on the date of the Indentures;

          (2) Liens securing Debt outstanding or available under all Credit
     Facilities to the extent such Debt is permitted under clause (i) of the
     "Limitation in Consolidated Debt";

          (3) Liens in favor of RSL COM or any Restricted Subsidiary;

          (4) Liens on real or personal property of RSL COM or a Restricted
     Subsidiary acquired, constructed or constituting improvements made after
     the date of original issuance of the notes to secure Purchase Money Debt
     which is Incurred for the construction, acquisition and improvement of
     Telecommunications Assets and is otherwise permitted under the Indentures,
     provided, however, that

             (a) the principal amount of any Debt secured by such a Lien does
        not exceed 100% of such purchase price or cost of construction or
        improvement of the property subject to such Liens,

             (b) such Lien attaches to such property prior to, at the time of or
        within 180 days after the acquisition, completion of construction or
        commencement of operation of such property and

             (c) such Lien does not extend to or cover any property other than
        the specific item of property (or portion thereof) acquired, constructed
        or constituting the improvements made with the proceeds of such Purchase
        Money Debt;

          (5) Liens to secure Acquired Debt, provided, however, that

             (a) such Lien attaches to the acquired asset prior to the time of
        the acquisition of such asset and

             (b) such Lien does not extend to or cover any other asset;

          (6) Liens to secure Debt Incurred to extend, renew, refinance or
     refund (or successive extensions, renewals, refinancings or refundings), in
     whole or in part, Debt secured by any Lien referred to in the foregoing
     clauses (1), (2), (4) and (5) so long as the principal amount of Debt so
     secured is not increased except as otherwise permitted under clause (3) of
     "--Limitation on Consolidated Debt" and, in the case of Liens to secure
     Debt incurred to extend, renew, refinance or refund Debt secured by a Lien
     referred to in the foregoing clause (1), (4) or (5), such Liens do not
     extend to any other property; and

          (7) Permitted Liens.

  LIMITATION ON ASSET DISPOSITIONS

     RSL COM may not, and may not permit any Restricted Subsidiary to, make any
Asset Disposition in one or more related transactions unless:

          (1) RSL COM or the Restricted Subsidiary, as the case may be, receives
     consideration for such disposition at least equal to the fair market value
     for the assets sold or disposed of as determined by the Board of Directors
     in good faith and, in the case of an Asset Disposition in an amount greater
     than $5 million, evidenced by a resolution of the Board of Directors filed
     with the Trustee; and

          (2) at least 75% of the consideration for such disposition consists
     of:

             (a) cash or readily marketable cash equivalents or the assumption
        of Debt of the Guarantors or RSL PLC (other than Debt that is
        subordinated to the new notes and the new notes guarantees) or of a
        Restricted Subsidiary and release from all liability on the Debt
        assumed; or

             (b) Telecommunications Assets.

     However, none of the provisions of this "Limitation on Asset Dispositions"
shall apply to the issuance or sale of capital stock of (x) deltathree.com,
(y) RSL COM Australia Holdings Pty. Limited or a newly-formed

                                       42

<PAGE>

parent or subsidiary thereof organized under the laws of Australia ("RSL
Australia") or (z) RSL Communications Spain S.A. or a newly-formed parent or
subsidiary thereof organized under the laws of Spain ("RSL Spain"), in each
case, made in compliance with clause (5) of "Limitation on Issuance and Sales of
Capital Stock of Restricted Securities" below.

     In the event and to the extent that the Net Available Proceeds received by
RSL COM or any of its Restricted Subsidiaries from one or more Asset
Dispositions occurring on or after the Closing Date in any period of 12
consecutive months exceed 10% of Consolidated Tangible Assets (determined as of
the date closest to the commencement of such 12-month period for which a
consolidated balance sheet of RSL COM and its subsidiaries have been filed with
the Commission), then RSL COM or RSL PLC shall or shall cause the relevant
Restricted Subsidiary to:

          (1) within twelve months after the date Net Available Proceeds so
     received exceed 10% of Consolidated Tangible Assets:

             (a) apply an amount equal to such excess Net Available Proceeds to
        permanently repay unsubordinated Debt of RSL COM or any Restricted
        Subsidiary providing a Subsidiary Guarantee pursuant to the "Limitation
        on Issuances of Guarantees by Restricted Subsidiaries" covenant or Debt
        of any other Restricted Subsidiary, in each case owing to a Person other
        than RSL COM or any of its Restricted Subsidiaries; or

             (b) invest an equal amount, or the amount not so applied pursuant
        to clause (a) (or enter into a definitive agreement committing to so
        invest within twelve months after the date of such agreement), in
        Telecommunications Assets; and

          (2) apply (no later than the end of the twelve-month period referred
     to in clause (1)) such excess Net Available Proceeds (to the extent not
     applied pursuant to clause (1)) as provided in the following paragraph of
     this "Limitation on Asset Dispositions" covenant.

     The amount of such excess Net Available Proceeds required to be applied (or
to be committed to be applied) during such twelve-month period as set forth in
clause (1) 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
"Limitation on Asset Dispositions" covenant totals at least $10 million, RSL PLC
shall repay any Debt of RSL COM or any Restricted Subsidiary to the extent the
terms of such Debt require repayment prior to an Offer to Purchase being made
hereunder (including by way of an offer to purchase to the holders of such Debt,
if so required). To the extent there are Excess Proceeds after such repayment
(or offer to purchase), RSL PLC must commence, not later than the fifteenth
Business Day of such month (or if later, the fifteenth Business Day after the
expiration of any such required offer to purchase), and consummate an Offer to
Purchase from the holders of the new notes on a pro rata basis an aggregate
principal amount of such new notes on the relevant Payment Date equal to the
Excess Proceeds on such date not applied or to be applied pursuant to the first
sentence of this paragraph, at a purchase price equal to 100% of the principal
amount of the new notes, plus, in each case, accrued interest (if any) to but
excluding the Payment Date and, to the extent required by the terms thereof, any
other Debt of RSL COM that is equal with the new notes at a price no greater
than 100% of the principal amount (or 100% of the accreted value in the case of
original issue discount Debt) thereof plus accrued interest to but excluding the
date of purchase. To the extent there are any remaining Excess Proceeds
following the completion of the Offer to Purchase, RSL PLC must repay such other
Debt of RSL COM or Debt of a Restricted Subsidiary, to the extent permitted
under the terms thereof and, to the extent there are any remaining Excess
Proceeds after such repayment, RSL PLC shall apply such amount to any other use
as determined by RSL PLC which is not otherwise prohibited by the Indentures.

  LIMITATION ON ISSUANCES AND SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES

     RSL COM may not, and may not permit any Restricted Subsidiary to, issue,
transfer, convey, sell or otherwise dispose of any shares of Capital Stock of a
Restricted Subsidiary or securities convertible or exchangeable into, or
options, warrants, rights or any other interest with respect to, Capital Stock
of a Restricted Subsidiary to any Person other than RSL COM or a Wholly-Owned
Restricted Subsidiary except:

          (1) a sale of all of the Capital Stock of such Restricted Subsidiary
     owned by RSL COM and any Restricted Subsidiary that complies with the
     provisions described under "Limitation on Asset Dispositions" above to the
     extent such provisions apply;

          (2) if required, the issuance, transfer, conveyance, sale or other
     disposition of directors' qualifying shares;

          (3) Disqualified Stock issued in exchange for, or upon conversion of,
     or the proceeds of the issuance of which are used to redeem, refinance,
     replace or refund shares of Disqualified Stock of such Restricted
     Subsidiary, provided that the amounts of the redemption obligations of such
     Disqualified Stock shall not exceed the amounts of the redemption
     obligations of, and such Disqualified Stock shall have redemption
     obligations no earlier than those required by, the Disqualified Stock being
     exchanged, converted, redeemed, refinanced, replaced or refunded;

          (4) issuances of not more than 49% of the Voting Stock and equity
     interest in a Restricted Subsidiary engaged in the Telecommunications
     Business:

             (a) in connection with the acquisition of such Restricted
        Subsidiary or of Telecommunications Assets acquired or to be acquired by
        RSL COM or a Restricted Subsidiary; or

             (b) to a Strategic Investor, provided that RSL COM complies with
        the provisions described under "Limitation on Asset Dispositions" above
        to the extent such provisions apply; and

          (5) issuances or sales of capital stock of each of deltathree.com, RSL
     Australia and RSL Spain, including pursuant to stock option plans or other
     equity compensation and incentive plans established for each of their
     respective employees, directors and consultants, so long as immediately
     after giving effect to such issuances and sales, RSL PLC of such capital
     stock is a Restricted Subsidiary.

  LIMITATION ON TRANSACTIONS WITH AFFILIATES AND RELATED PERSONS

     RSL COM 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 Related Person or with any Affiliate
of RSL COM or any Restricted Subsidiary, except upon fair and reasonable terms
no less favorable to RSL COM 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 a
Related Person or an Affiliate.

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

          (1) transactions:

             (a) approved by a majority of the disinterested members of the
        Board of Directors; or

             (b) for which RSL COM or a Restricted Subsidiary delivers to the
        Trustee a written opinion of a nationally recognized investment banking
        firm (or a subsidiary or affiliate thereof) in the United States stating
        that the transaction is fair to RSL COM or such Restricted Subsidiary
        from a financial point of view;

          (2) any transaction solely between RSL COM and any of its Wholly-Owned
     Restricted Subsidiaries or solely between Wholly-Owned Restricted
     Subsidiaries; and

                                       44

<PAGE>

          (3) any payments or other transactions pursuant to any tax-sharing
     agreement between RSL COM and any other Person with which RSL COM files a
     consolidated tax return or with which RSL COM is part of a consolidated
     group for tax purposes.

     Notwithstanding the foregoing, any transaction covered by the first
paragraph of this "Limitation on Transactions with Affiliates and Related
Persons" covenant and not covered by clauses (2) through (3) of this paragraph
must be approved or determined to be fair in the manner provided for in clause
(1) above, unless the aggregate amount of such transaction is less than $5
million in value.

  CHANGE OF CONTROL

     Unless RSL PLC has theretofore exercised its right to redeem all of the new
notes in accordance with the Indentures, within 30 days of the occurrence of a
Change of Control, RSL PLC will be required to make an Offer to Purchase all
outstanding new notes at a purchase price equal to 101% of their principal
amount plus accrued interest to but excluding the date of purchase. A "Change of
Control" will be deemed to have occurred at such time as either:

          (1) a "person" or "group" (within the meaning of Sections 13(d) and
     14(d)(2) of the Exchange Act) becomes the ultimate "beneficial owner" (as
     defined in Rule 13d-3 under the Exchange Act) of more than 35% of the total
     voting power of the Voting Stock of RSL COM on a fully diluted basis and
     such ownership is greater than the amount of voting power of the Voting
     Stock of RSL COM, on a fully diluted basis, held by the Existing
     Stockholders and their Affiliates on such date;

          (2) individuals who on the Closing Date constitute the Board of
     Directors (together with any new directors whose election by the Board of
     Directors or whose nomination for election by the Guarantor's stockholders
     was approved by a vote of at least two-thirds of the members of the Board
     of Directors then in office who either were members of the Board of
     Directors on the Closing Date or whose election or nomination for election
     was previously so approved) cease for any reason to constitute a majority
     of the members of the Board of Directors then in office; or

          (3) all of the Common Stock of RSL PLC is not beneficially owned by
     RSL COM (other than directors' qualifying shares). (ss.1017)

     In the event that RSL PLC makes an Offer to Purchase the notes, RSL PLC and
the Guarantors intend to comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and Rule
14e-1 under, the Exchange Act.

  REPORTS

     The Guarantors and RSL PLC have agreed that, for so long as any new notes
remain outstanding, each will furnish to the holders of the new notes and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act. In addition, the Guarantors and RSL PLC will file with the
Trustee within 15 days after it files them with the Commission copies of the
annual and quarterly reports and the information, documents, and other reports
that either Guarantor or RSL PLC is required to file with the Commission
pursuant to Section 13(a) or 15(d) of the Exchange Act ("Commission Reports").
In the event either Guarantor or RSL PLC shall cease to be required to file
Commission Reports pursuant to the Exchange Act, the Guarantors and RSL PLC will
nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing) and the Trustee. The Guarantors and
RSL PLC will furnish copies of the Commission Reports to the holders of notes at
the time the Guarantors or RSL PLC is required to file the same with the Trustee
and will make such information available to investors who request it in writing.
(ss. 1018)

  MERGERS, CONSOLIDATIONS AND CERTAIN SALES OF ASSETS

     Neither RSL COM, RSL PLC nor, so long as its notes guarantees have not been
released as provided below under "Description of New Notes Guarantees," RSL USA
may, in a single transaction or a series of related transactions, (except, in
the case of RSL USA, in any transaction or series of related transactions as a
result of which RSL USA's notes guarantees will be released) (a) consolidate
with or merge into any other Person or

                                       45

<PAGE>

permit any other Person to consolidate with or merge into either Guarantor or
RSL PLC, or (b) directly or indirectly, transfer, sell, lease or otherwise
dispose of all or substantially all of its assets to any other Person, unless:

          (1) in a transaction in which either Guarantor or RSL PLC, as
     applicable does not survive or in which either Guarantor or RSL PLC sells,
     leases or otherwise disposes of all or substantially all of its assets to
     any other Person (other than, in any such case, either Guarantor or RSL
     PLC), the successor entity to such Guarantor or RSL PLC is organized under
     the laws of Bermuda, the United Kingdom, the United States of America or
     any State thereof or the District of Columbia, the British Virgin Islands,
     Cayman Islands, The Netherlands, Ireland or Jersey and shall expressly
     assume, by a supplemental indenture executed and delivered to the Trustee
     in form satisfactory to the Trustee, all of such Guarantor's or RSL PLC's
     obligations under the Indentures;

          (2) immediately before and after giving effect to such transaction and
     treating any Debt which becomes an obligation of the Guarantors or a
     Subsidiary as a result of such transaction as having been Incurred by the
     Guarantors or such Subsidiary at the time of the transaction, no Event of
     Default or event that with the passing of time or the giving of notice, or
     both, would constitute an Event of Default shall have occurred and be
     continuing;

          (3) immediately after giving effect to such transaction, the
     Consolidated Net Worth of RSL COM (or other successor entity to RSL COM) is
     equal to or greater than that of RSL COM immediately prior to the
     transaction;

          (4) if, as a result of any such transaction, property or assets of RSL
     COM or any Subsidiary would become subject to a Lien prohibited by the
     provisions of the Indentures described under "Limitation on Liens" above,
     RSL COM or the successor entity to RSL COM shall have secured the notes as
     required by said covenant;

          (5) in the event that the continuing Person is incorporated in a
     jurisdiction other than the United States or the jurisdiction in which such
     Person was incorporated immediately prior to such transaction:

             (a) RSL PLC delivers to the Trustee an Opinion of Counsel stating
        that the obligations of the continuing Person under the Indentures are
        enforceable under the laws of the new jurisdiction of its incorporation
        to the same extent as the obligations of RSL PLC or such Guarantor, as
        the case may be, under the Indentures immediately prior to such
        transaction;

             (b) the continuing Person agrees in writing to submit to
        jurisdiction and appoints an agent for the service of process, each
        under terms substantially similar to the terms contained in the
        Indentures with respect to RSL PLC or such Guarantor, as the case may
        be;

             (c) the continuing Person agrees in writing to pay "Additional
        Amounts" as provided under the Indentures with respect to RSL PLC or
        such Guarantor, as the case may be, except that such "Additional
        Amounts" shall relate to any withholding tax whatsoever regardless of
        any change of law (subject to exceptions substantially similar to those
        contained in the Indentures and described under the heading "Additional
        Amounts");

             (d) the Board of Directors of such Guarantor determines in good

     Debt of either Guarantor, RSL PLC or any Subsidiary having an outstanding

     appeal) against either Guarantor, RSL PLC or any Subsidiary of an amount in

Trustee in case an Event of Default (as defined) shall occur and be continuing,
the Trustee will be under no obligation to exercise any of its rights or powers

indemnity. (ss. 603) Subject to such provisions for the indemnification of the

acceleration, the holders of a majority in aggregate principal amount at
maturity of such outstanding new notes may, under certain circumstances, rescind
and annul such acceleration if all Events of Default, other than the non-payment
of accelerated principal amount have been cured or waived as provided in the
Indentures. If an Event of Default specified in clause (8) above occurs, the

(ss. 502) For information as to waiver of defaults, see the heading
"Modification and Waiver."

     No holder of any new note will have any right to institute any proceeding
with respect to the Indentures or for any remedy thereunder, unless such holder
shall have previously given to the Trustee written notice of a continuing Event
of Default (as defined) and unless also the holders of at least 25% in aggregate
principal amount at maturity of the outstanding new notes shall have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as trustee, and the Trustee shall not have received from the
holders of a majority in aggregate principal amount at maturity of the
outstanding new notes a direction inconsistent with such request and shall have
failed to institute such proceeding within 60 days. (ss. 507) However, such
limitations do not apply to a suit instituted by a holder of a new note for
enforcement of payment of the principal amount of and premium, if any, or
interest on such new note on or after the respective due dates expressed in such
note. (ss. 508)

     The Guarantors and RSL PLC will be required to furnish to the Trustee

any amounts that would have been received but for such exercise of its option

event that after the giving of notice or lapse of time or both would become a
Default or 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 RSL
PLC or any of its Subsidiaries is a party or by which RSL PLC or any of its
Subsidiaries is bound, (E) if at such time the new notes are listed on a
national securities exchange, RSL PLC has delivered to the Trustee an Opinion of
Counsel to the effect that the new notes will not be delisted as a result of RSL
PLC's exercise of its option under this "Defeasance" provision, and (F) RSL PLC
shall have delivered to the Trustee an Officer's Certificate and an Opinion of
Counsel, in each case stating that all the above conditions precedent have been
complied with.

     Defeasance of Certain Covenants and Certain Events of Default.  The
Indentures further will provide that the provisions of the Indentures will no
longer be in effect with respect to clauses (3) and (4) under "Mergers,
Consolidations and Certain Sale of Assets" and all the covenants described
herein under "Covenants" (other than "Mergers, Consolidations and Certain Sales
of Assets"), clauses (c), (f) and (g) under "Events of Default" with respect to
such clauses (3) and (4) under "Mergers, Consolidations and Certain Sale of
Assets" and such covenants and clauses (c), (f) and (g) under "Events of
Default" shall be deemed not to be Events of Default, upon, among other things,
the deposit with the Trustee, in trust, of money and/or U.S. 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
new notes on the stated maturity of such payments in accordance with the terms
of the Indentures and the new notes, the satisfaction of the provisions
described in clauses (C)(2) and (D) of the preceding paragraph and the delivery
by RSL PLC to the Trustee of an Opinion of Counsel to the effect that, among
other things, the holders will not recognize any income, gain or loss for U.S.
federal income tax purposes as a result of such deposit and defeasance of
certain covenants and Events of Default and will be subject to U.S. 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.

     Defeasance and Certain Other Events of Default.  In the event RSL PLC
exercises its option to omit compliance with certain covenants and provisions of
the Indentures with respect to the new notes as described in the immediately
preceding paragraph and the new notes are declared due and payable because of
the occurrence of an Event of Default that remains applicable, the amount of
money and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the new notes at the time of their stated
maturity but may not be sufficient to pay amounts due on the new notes at the
time of the acceleration resulting from such Event of Default. However, RSL PLC
will remain liable for such payments and the new notes guarantees with respect
to such payments will remain in effect.

MODIFICATION AND WAIVER

     Modifications and amendments of the Indentures may be made by RSL PLC, the
Guarantors and the Trustee with the consent of the holders of a majority in
aggregate principal amount of the outstanding new notes; provided, however, that
no such modification or amendment may, without the consent of the holder of each
outstanding new note, affected thereby, (a) change the due date of any
installment of principal or interest on any new notes, (b) reduce the principal
amount of, (or the premium) or interest on, any new notes, (c) change the
currency of payment of principal of, (or premium) or interest on, any new notes,
(d) impair the right to institute suit for the enforcement of any payment on or
with respect to any new notes, (e) reduce the above-stated percentage of
outstanding new notes necessary to modify or amend the Indentures, (f) reduce
the percentage of aggregate principal amount of outstanding new notes necessary
for waiver of compliance with certain provisions of the Indentures or for waiver
of certain defaults, (g) modify any provisions of the Indentures relating to the
modification and amendment of the Indentures or the waiver of past defaults or
covenants, except as otherwise

                                       60

<PAGE>

specified, or (h) following the mailing of any Offer to Purchase, modify any
Offer to Purchase for the new notes required under the "Limitation on Asset
Dispositions" and the "Change of Control" covenants contained in the Indentures
in a manner materially adverse to the holders thereof. (ss. 902)

     The holders of a majority in aggregate principal amount of the outstanding
new notes, on behalf of all holders of new notes, may waive compliance by the
Guarantors and RSL PLC with certain restrictive provisions of the Indentures.
(ss. 1020) Subject to certain rights of the Trustee, as provided in the
Indentures, the holders of a majority in aggregate principal amount of the
outstanding new notes, on behalf of all holders of new notes, may waive any past
default under the Indentures, except a default in the payment of principal,
premium or interest or a default arising from failure to purchase any note
tendered pursuant to an Offer to Purchase. (ss. 513)

     Notwithstanding the foregoing, without the consent of any holder of new
notes, the Guarantors and the Trustee may amend or supplement the Indentures and
the new notes:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to provide for uncertificated new notes in addition to or in place
     of certificated new notes;

          (c) to provide for the assumption of obligations of RSL PLC and the
     Guarantors to holders of the new notes in the case of a transaction
     governed by the provisions described above under "Mergers, Consolidations
     and Certain Sales of Assets" or to secure the new notes;

          (d) to make any change that would provide any additional rights or
     benefits to the holders of the new notes or that does not adversely affect
     the legal rights under the Indentures of any such holder; or

          (e) to comply with requirements of the Commission in order to effect
     or maintain the qualification of the Indentures under the Trust Indentures
     Act. (ss. 901).

THE TRUSTEE

     The Indentures provide that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indentures. During the existence of an Event of Default, the Trustee will
exercise such rights and powers vested in it under the Indentures and use the
same degree of care and skill in its existence as a prudent person would
exercise under the circumstances in the conduct of such person's own affairs.
(ss. 601)

     The Indentures and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of RSL PLC or either Guarantor, to obtain payment of claims in
certain cases or to realize on certain property received by it in respect of any
such claim as security or otherwise. The Trustee is permitted to engage in other
transactions with RSL PLC, the Guarantors or any Affiliate, provided, however,
that if it acquires any conflicting interest (as defined in the Indentures or in
the Trust Indenture Act), it must eliminate such conflict or resign.
(ss.ss. 608, 613)

ADDITIONAL AMOUNTS

     Payments made by RSL PLC or the Guarantors pursuant to the new notes or the
new notes guarantees will be made without withholding or deduction for taxes
unless required by law. In the event of (1) any change that becomes effective
after the date hereof in the laws of the U.K. or Bermuda or of any political
subdivision or taxing authority thereof or therein or any change in the
interpretation or administration thereof or (2) a failure by RSL PLC to list or
maintain a listing of the new notes on a "recognized stock exchange" (within the
meaning of Section 841 of the U.K. Income and Corporation Taxes Act 1988) (a
"Listing Failure"), the effect of which, in each case, is to require the
withholding or deduction by RSL PLC or the Guarantors pursuant to the new notes
or the new notes guarantees, respectively, of any amount for taxes that would
not have been required to be withheld or deducted absent such event, RSL PLC or
the Guarantors will pay, to the extent it may then lawfully do so, such
additional amounts ("Additional Amounts") as may be necessary in order that
every net payment of the principal of and interest on the new notes, after
deduction for withholding for or on account of any future tax, assessment or
other governmental charge will not be less than the amount provided for in the
notes to be then due

                                       61

<PAGE>

and payable; provided, however, that the foregoing obligation to pay Additional
Amounts shall not apply in respect of:

          (a) any tax, withholding, assessment or other governmental charge
     which would not have been imposed but for (x) the existence of any present
     or former connection between such holder (or between a fiduciary, settlor,
     beneficiary, member or shareholder of, or possessor of a power over, such
     holder, if such holder is an estate, trust, partnership or corporation) and
     the U.K. or Bermuda or any political subdivision or taxing authority
     thereof including, without limitation, such holder (or such fiduciary,
     settlor, beneficiary, member, shareholder or possessor) being or having
     been a citizen or resident thereof or being or having been present or
     engaged in trade or business therein or having or having had a permanent
     establishment therein or (y) the presentation of a new note or a new notes
     guarantee (where presentation is required) for payment on a date more than
     30 days after the date on which such payment became due and payable or the
     date on which payment thereof is duly provided for, whichever occurs later,
     except for Additional Amounts with respect to taxes that would have been
     imposed had the holder presented the note for payment within such 30-day
     period;

          (b) any estate, inheritance, gift, sale, transfer or personal property
     tax;

          (c) any tax, assessment or other governmental charge that is withheld
     by reason of the failure to timely comply by the holder or the beneficial
     owner of the new note with a request in writing of RSL PLC or either
     Guarantor (which request shall be furnished to the Trustee) (x) to provide
     information concerning the nationality, residence or identity of the holder
     or such beneficial owner or (y) to make any declaration or other similar
     claim or satisfy any information or reporting requirement, which, in the
     case of (x) or (y), is required or imposed by a statute, treaty, regulation
     or administrative practice of the taxing or domicile jurisdiction as a
     precondition to exemption from or reduction of all or part of such tax,
     assessment or other governmental charge; provided, however, that this
     clause (c) shall not apply to limit RSL PLC's or the Guarantors' obligation
     to pay Additional Amounts if the completing and filing of the information
     described in subclause (x) or the declaration or other claim described in
     subclause (y) would be materially more onerous in form, in procedure or in
     substance of information disclosed, in comparison to the information
     reporting requirements imposed under U.S. tax law with respect to Forms
     1001, W-8 and W-9; or

          (d) any tax, withholding, assessment or other governmental charge
     resulting from a Listing Failure with respect to any note issued in the
     form of a Definitive Registered Note pursuant to the terms of the Deposit
     Agreement and the relevant Indentures; or

          (e) any combination of items (a), (b),(c) and (d) above; nor shall
     Additional Amounts be paid with respect to any payment of the principal of,
     or any interest on, any new note or new notes guarantees to any holder who
     is not the sole beneficial owner of such new note or new notes guarantees
     or is a fiduciary or partnership, but only to the extent that a beneficial
     owner, a beneficiary or a settlor with respect to a fiduciary or a member
     of the partnership would not have been entitled to the payment of the
     Additional Amount had the beneficial owner, beneficiary, settlor or member
     of such partnership received directly its beneficial or distributive share
     of the payment.

     At least 30 days prior to each date on which any payment under or with
respect to the new notes is due and payable, if RSL PLC or the Guarantors will
be obligated to pay Additional Amounts with respect to such payment, RSL PLC or
the Guarantors will deliver to the Trustee an Officer's Certificate stating the
fact that such Additional Amounts will be payable and the amounts so payable and
will set forth such other information necessary to enable the Trustee to pay
such Additional Amounts to Holders on the payment date. Whenever in the
Indentures or in this offering circular there is mentioned, in any context, the
payment of principal (and premium, if any), redemption price, interest or any
other amount payable under or with respect to any new note, such mention shall
be deemed to include mention of the payment of Additional Amounts to the extent
that, in such. context, Additional Amounts are, were or would be payable in
respect thereof. See the heading "Optional Redemption."

     RSL PLC or the Guarantors, as the case may be, will also (1) make (or cause
to be made) such withholding or deduction and (2) remit (or cause to be
remitted) the full amount deducted or withheld to the relevant authority in
accordance with applicable law. RSL PLC or the Guarantors, as the case may be,
will make reasonable efforts

                                       62

<PAGE>

to obtain certified copies of tax receipts evidencing the payment of any taxes
so deducted or withheld from each taxing authority imposing such taxes. RSL PLC
or the Guarantors, as the case may be, will furnish to the Trustee as promptly
as practicable after the payment of any taxes so deducted or withheld is due
pursuant to applicable law, either certified copies of tax receipts evidencing
such payment or, if the receipts are not obtainable, other evidence of such
payments by RSL PLC or the Guarantors.

CONSENT TO JURISDICTION AND SERVICE

     RSL COM, RSL USA and RSL PLC have appointed RSL Communications N. America,
Inc. as their agent for service of process in any suit, action or proceeding
with respect to the Indentures or the new notes or the new notes guarantees and
for actions brought under federal or state securities laws brought in any
federal or state court located in the City of New York and will agree to submit
to such jurisdiction.

GOVERNING LAW

     The Indentures, the new notes and the new notes guarantees are governed by,
and construed in accordance with, the laws of the State of New York.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following summary describes the material U.S. federal income tax
consequences of the exchange of old notes for new notes as of the date hereof.
Such summary is not binding on any taxing authority or the courts, and no U.S.
tax ruling has been or will be sought. The discussion below is based upon the
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and
regulations, rulings and judicial decisions as of the date hereof, and such
authorities may be repealed, revoked or modified so as to result in U.S. federal
income tax consequences different from those discussed below. Certain holders
(including insurance companies, tax-exempt organizations, financial
institutions, broker-dealers, foreign corporations and persons who are not
citizens or residents of the United States) may be subject to special rules not
discussed below.

     The exchange of an old note for a corresponding new note pursuant to the
exchange offer will not be a taxable event for U.S. federal income tax purposes
because such new note will not be considered to differ materially in kind or
extent from the corresponding old note. As a result, there should be no material
U.S. federal income tax consequences to a holder exchanging an old note for a
corresponding new note pursuant to the exchange offer.

     Each holder of old notes should consult his, her or its own tax advisor as
to the particular tax consequences of exchanging old notes for new notes,
including the applicability and effect of any state, local or foreign tax laws.

                   CERTAIN UNITED KINGDOM TAX CONSIDERATIONS

     The following summary describes the material U.K. income and capital gains
tax consequences expected to result to holders whose old notes are exchanged for
new notes in the exchange offer. This summary is based on current U.K. law and
U.K. Inland Revenue practice which may change prospectively or retrospectively.
There can be no assurance that the U.K. Inland Revenue would not take a contrary
view and no ruling from the U.K. Inland Revenue has been or will be sought.

     For U.K. tax purposes, the exchange of the old notes for the new notes will
have no U.K. capital gains tax consequences for a U.S. holder who is neither
resident nor ordinarily resident in the U.K. (nor has become non-U.K. resident
or ordinarily resident in the last five tax years), nor carries on a trade,
profession or vocation in the U.K. through a branch or agency to which the new
notes are attributable.

     U.S. holders should be aware that, under current U.K. law, upon the
issuance to the holder of Definitive Registered Notes, such holder will become
subject to U.K. income tax (currently 20%) to be withheld on any payments of
interest on the Definitive Registered Notes. The U.S. holder of Definitive
Register Notes will not, unless there has been a change in law or a "Listing
Failure" (as defined herein) and certain other conditions are met, be entitled
to receive Additional Amounts (as referred to above) with respect to such
Definitive Registered Notes. However, a U.S. holder of Definitive Registered
Notes may be entitled to receive a refund of part of the withheld amounts from
the Inland Revenue in certain circumstances.

     In May 1998, the European Commission presented to the Council of Ministers
of the European Union a proposal to oblige Member States to adopt either a
"withholding tax system" or an "information reporting system" in relation to
interests, discounts and premiums. This proposal was not adopted and it is
uncertain whether or not it will be reconsidered. If it is subsequently adopted,
it is not clear whether it will be adopted in its original form. The
"withholding tax system" would require a paying agent established in a Member
State to withhold tax at a minimum rate of 20 per cent from any discount paid to
an individual resident in another Member States unless such an individual
presents a certificate obtained from the tax authorities of the Member State in
which he is resident confirming that those authorities are aware of the payment
due to that individual. Difficulties in establishing who is beneficially
entitled to the income might result in a payment being subject to withholding
tax where the income is collected by an agent in a Member State. The
"information reporting system" would require a Member State to supply, to the
other Member States, details of any discount made by the paying agents within
its jurisdiction to an individual resistant in another Member State. For these
purposes, the term "paying agent" is widely defined and includes an agent who
collects discounts on behalf of an individual beneficially entitled thereto.

<PAGE>

                              PLAN OF DISTRIBUTION

     A broker-dealer that is the holder of old notes that were acquired for the
account of such broker-dealer as a result of market-making or other trading
activities (other than old notes acquired directly from RSL PLC or any affiliate
of RSL PLC) may exchange such old notes for new notes pursuant to the exchange
offer, provided, that each broker-dealer that receives new notes for its own
account pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such new notes. This prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of new notes received in exchange for
old notes where such old notes were acquired as a result of market-making
activities or other trading activities. RSL PLC has agreed to keep the
Registration Statement effective for a period of 90 days following the closing
of the exchange offer.

     RSL PLC will not receive any proceeds from any sale of new notes by
broker-dealers or any holder of new notes. New notes received by broker-dealers
for their own account pursuant to the exchange offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the new notes or a combination
of such methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
such broker-dealer and/or the purchasers of new notes. Any broker-dealer that
resells new notes that were received by it for its own account pursuant to the
exchange offer and any broker or dealer that participates in a distribution of
such new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of new notes and any
commissions or concessions received by any such persons may be deemed to be an
underwriting compensation under the Securities Act. The letter of transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     RSL PLC has agreed to pay all expenses incident to the exchange offer and
to RSL PLC's performance of, or compliance with, the registration rights
agreement (other than commissions or concessions of any brokers or dealers) and
will indemnify the holders of the new notes (including any broker-dealers)
against any liabilities under the Securities Act.

     Following consummation of the exchange offer, RSL PLC may, in its sole
discretion, commence one or more additional exchange offers to holders of old
notes who did not exchange their old notes for new notes in the exchange offer
on terms which may differ from those contained in the registration rights
agreement. This prospectus, as it may be amended or supplemented from time to
time, may be used by RSL PLC in connection with any such additional exchange
offers. Such additional exchange offers will take place from time to time until
all outstanding old notes have been exchanged for new notes pursuant to the
terms and conditions contained herein.

                                 LEGAL MATTERS

     Certain matters relating to the new notes are being passed upon for us by
Field Fisher Waterhouse, London, United Kingdom. Certain matters relating to the
new notes and the new notes guarantees are being passed upon for us by Debevoise
& Plimpton, New York, New York and by Conyers, Dill & Pearman, Hamilton,
Bermuda.

                                    EXPERTS

     The consolidated financial statements included in this prospectus have been
audited by Deloitte & Touche LLP, independent auditors, as stated in their
report appearing herein and elsewhere in this Registration Statement and are
included in reliance upon the report of such firm given upon their authority as
experts in accounting and auditing.

               SERVICE OF PROCESS AND ENFORCEMENT OF LIABILITIES

     RSL COM is a Bermuda corporation and RSL PLC is a United Kingdom
corporation. Certain of their directors and officers, and certain of the experts
named herein, are not residents of the United States. All or a substantial
portion of the assets of such persons are or may be located outside the United
States. As a result, it may not be possible for investors to effect service of
process within the United States upon such persons or to enforce against them
judgments obtained in the United States courts. RSL COM has been advised by its
legal counsel in Bermuda, Conyers, Dill & Pearman, that there is doubt as to the
enforcement in Bermuda, in original actions or in actions for enforcement of
judgments of United States courts, or liabilities predicated upon U.S. Federal
securities laws, although Bermuda courts will enforce foreign judgments for
liquidated amounts in civil matters, subject to certain conditions and
exceptions. RSL PLC has been advised by its legal counsel in the United Kingdom,
Field Fisher Waterhouse, that there is doubt as to the enforceability of certain
civil liabilities under U.S. Federal securities laws in original actions of
English courts, but that, subject to certain exceptions and time limitations,
English courts may treat a final and conclusive judgment of a U.S. court for a
liquidated amount as a debt enforceable by fresh proceedings in the English
courts. Such counsel has expressed no opinion, however, as to whether an
enforcement by an English court of any judgment would be in pounds sterling or
as of which date, if any, the determination of the applicable exchange rate from
U.S. dollars to pounds sterling may be made.

     Each of RSL PLC, RSL COM and RSL USA has appointed RSL Communications N.
America, with an address at 810 Seventh Avenue, 39th Floor, New York, New York
10019, as its agent for services for this offering of the new notes.

                          INDEPENDENT AUDITORS' REPORT

To the Shareholders of
RSL Communications, Ltd.

        We have audited the accompanying consolidated balance sheets of RSL
Communications, Ltd., a Bermuda corporation, and its subsidiaries (together, the
"Company"), as of December 31, 1999 and 1998, and the related consolidated
statements of operations and comprehensive loss, shareholders' equity (deficit)
and cash flows for each of the three years in the period ended December 31,
1999. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

        In our opinion, such consolidated financial statements present fairly,
in all material respects, the consolidated financial position of the Company and
its subsidiaries at December 31, 1999 and 1998 and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States of America.

2. ACQUISITIONS--(CONTINUED)

Accounting Treatment

     Acquisitions, unless otherwise stated, have been accounted for by the
purchase method of accounting and, accordingly, the purchase prices have been
allocated to the assets acquired, primarily fixed assets, accounts receivable
and customer bases, and liabilities assumed based on their estimated fair values
at the dates of acquisition. The excess of the purchase price over the estimated
fair values of the net assets acquired has primarily been recorded as goodwill,
which is amortized over five to twenty years. The valuation of our acquired
assets and liabilities for the 1999 acquisitions are preliminary and as a
result, the allocation of the acquisition costs among the tangible and
intangible assets may change.

     The following presents our unaudited pro forma consolidated statements of
operations data for the years ended December 31, 1997 and 1998 as though the
acquisitions of Westinghouse, Westel, LDM, Call Australia Group, and EZI had
occurred on January 1, 1997. All other acquisitions had insigificant operations
prior to the date of acquisition. The unaudited pro forma consolidated
statements do not necessarily represent what our results of operations would
have been had such acquisitions actually occurred on such date.

Europe. In June 1998, Metro Holding converted all of its interest in RSL Europe
into 1,607,142 shares of our Class A Common Stock (based on value for value) and
purchased an equal number of Class A Common Stock from certain of our
shareholders. In the aggregate at December 31, 1999, Metro Holding holds
approximately 5.8% of our outstanding stock, which it is required to hold until
at least April 1, 2001. We have recorded in the consolidated financial
statements the issuance of such equity at fair market value, $45 million, based
on the quoted market value of our stock at the time of the transaction, and have
recorded the distribution rights as an intangible asset in a like amount which
is being amortized over the five-year life of the agreement.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation and Basis of Presentation--The consolidated
financial statements include the accounts of RSL Communications, Ltd. and its
majority-owned subsidiaries from the date of acquisition or commencement of
operations. All significant intercompany transactions have been eliminated in
consolidation.

     We have majority ownership of all of our subsidiaries except for Maxitel,
MK Network and Cetel which we account for under the equity method of accounting.

     Management Assumptions--The preparation of the consolidated financial
statements requires us to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities and the reported amounts of revenues and expenses. Such
estimates primarily relate to

                                      F-12

reserves recorded for doubtful accounts and accruals for other claims. Actual
results could differ from these estimates.

     Foreign Currency Translation and Transaction--Local currencies are
considered the functional currencies of our foreign operating entities. Assets
and liabilities of foreign entities have been translated into United States
dollars using the exchange rates in effect at the balance sheet dates. Results
of operations of foreign entities are translated using the average exchange
rates prevailing throughout the period. We utilize a net settlement process with
our correspondents comprised of special drawing rights ("SDRs"). SDRs are the
established method of settlements among international telecommunications
carriers. The SDRs are valued based upon the values of a basket of foreign
currencies. Translation effects are accumulated as part of other comprehensive
loss in equity. Gains and losses from foreign currency transactions are included
in the consolidated statements of operations and comprehensive loss. Foreign
currency transaction gains for the year ended December 31,1999 were $17 million
as compared to losses for the year ended December 31, 1998 of $11 million
primarily as a result of the decrease in the Deutsche mark against the U.S.
dollar in 1999 as compared with an increase in the Deutsche mark against the
U.S. dollar in 1998 in connection with our 1998 Deutsche mark denominated Senior
Discount Notes.

     Cash and Cash Equivalents--We consider all highly liquid investments
purchased with an original maturity of three months or less to be cash
equivalents.

     Accounts Receivable--Accounts receivable are stated net of the allowance
for doubtful accounts of approximately $26,000,000 and $37,000,000 at December
31, 1998 and 1999, respectively. We recorded bad debt expense of approximately
$10,900,000, $9,000,000 and $18,000,000 for the years ended December 31, 1997,
1998 and 1999, respectively.

     Accrued Expenses--Accrued expenses for the years ended December 31, 1998
and 1999 consist primarily of accrued interest, accrued acquisition costs and
accrued transmission costs.

     Marketable Securities--Marketable securities consist principally of U.S.
Treasury bills, commercial paper and corporate notes with a maturity date
greater than three months when purchased. Available for sale securities are
stated at the lower of amortized cost or market value, and the held to maturity
securities are stated at amortized cost. Gains and losses, both realized and
unrealized, are measured using the specific identification method. Market value
is determined by the most recently traded price of the security at the balance
sheet date. Marketable securities are defined as either available for sale or
held to maturity securities under the provisions of SFAS No. 115, "Accounting
for Certain Investments in Debt and Equity Securities," depending on the
security.

     Property and Equipment and Related Depreciation--Property and equipment are
stated at cost or fair value at the date of acquisition, and in the case of
equipment under capital leases, the present value of the future minimum lease
payments, less accumulated depreciation and are amortized over the remainder of
the life. Depreciation is calculated using the straight-line method over the
estimated useful lives of the depreciable assets, which range from three to
fifteen years. Improvements are capitalized, while repair and maintenance costs
are charged to operations as incurred. Depreciation expense was $9,794,000,
$32,439,000 and $90,477,000 for the years ended December 31, 1997, 1998 and
1999, respectively.

     Impairment of Assets--Our long-lived assets and identifiable intangibles
are reviewed for impairment whenever events or changes in circumstances indicate
that the net carrying amount may not be recoverable. When such events occur, we
measure impairment by comparing the carrying value of the long-lived asset to
the estimated undiscounted future cash flows expected to result from the use of
the assets and their eventual disposition. If the sum of the expected
undiscounted future cash flows is less than the carrying amount of the assets,
we would recognize an impairment loss. The impairment loss, if determined to be
necessary, would be measured as the amount by which the carrying amount of the
asset exceeds the fair value of the asset. We determined that, as of December
31, 1998 and 1999, there had been no impairment in the carrying value of the
long-lived assets.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

     Goodwill and Related Amortization--Goodwill represents the excess of cost
over the fair value of the net assets of acquired entities, and is being
amortized using the straight-line method over five to twenty years. We
periodically review the value of our goodwill to determine if an impairment has
occurred. We measure the potential impairment of recorded goodwill by the
undiscounted value of expected future cash flows in relation to our net goodwill
in our subsidiary. Based on our review, we do not believe that an impairment of
our goodwill has occurred as of December 31, 1998 and 1999.

     Other Intangible Assets--Other intangible assets acquired through purchase
acquisitions include distribution rights, customer bases and operating licenses
which are being amortized over lives ranging from two to five years using the
straight-line method. Deferred financing costs incurred in connection with the
Senior Notes are being amortized on a straight-line basis over ten years.

     Deposits and Other Assets--Deposits consist principally of amounts paid to
our carrier vendors.

     Revenue Recognition and Deferred Revenue--We record revenue based on
minutes (or fractions thereof) of customer usage. We record payments received in
advance for prepaid calling card services and services to be supplied under
contractual agreements as deferred revenue until such related services are
provided.

     Other Liabilities--Other liabilities consists primarily of value-added tax
and payroll and related benefits obligations.

     Cost of Services--Cost of services is comprised primarily of transmission
costs.

     Selling Expenses--Selling costs such as recurring commissions and marketing
costs are treated as period costs. Customer acquisition costs, primarily related
to our cellular businesses, are amortized over the average lives of the
contracts of approximately twelve months. Such costs are recorded in selling,
general and administrative expenses in our consolidated statements of operations
and comprehensive loss.

     Income Taxes--We account for income taxes under the provisions of Statement
of Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income
Taxes". SFAS No. 109 establishes financial accounting and reporting standards
for the effect of income taxes that result from activities during the current
and preceding years. SFAS No. 109 requires an asset and liability approach for
financial reporting for income taxes. Our foreign subsidiaries file separate
income tax returns in the jurisdiction of their operations. Our United States
subsidiaries file stand-alone United States income tax returns.

     Loss per Common Share--Our loss per common share is calculated by dividing
the loss attributable to common shares by the weighted average number of shares
outstanding. Outstanding common stock options and warrants are not included in
the loss per common share calculation as their effect is antidilutive.

     Sales of Subsidiary Stock--During 1999 our subsidiaries Telegate AG and
deltathree.com issued common shares in connection with their initial public
offerings raising $144.0 million in the aggregate. We recorded our share of the
net proceeds of these sales as additional paid in capital.

Effects of Recently Issued Accounting Standards

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which establishes accounting and reporting
standards for derivative instruments and hedging activities. Generally, it
requires that an entity recognize all derivatives as either an asset or
liability and measure those instruments at fair value, as well as identify the
conditions for which a derivative may be specifically designed as a hedge. SFAS
No. 133 is effective for fiscal years beginning after June 15, 2000. We have not
participated in any hedging activities in connection with foreign currency
exposure.

Reclassification

     Certain previously reported amounts have been reclassified to conform with
the current period presentation.

4. SPECIAL CHARGE

     During the third quarter of 1999, we recorded a special charge of
approximately $32.1 million, primarily for consolidating locations, streamlining
operations, discontinuing certain prepaid calling card plans and exiting the
telemarketing business. The special charge is comprised of approximately
$13.1 million for terminating various operating leases, $12.4 million for the
severance of 74 telemarketing employees, as well as world-wide staff reductions
of 115 employees, and $6.6 million for the write down of certain telemarketing
and prepaid calling card assets of which $2.0 million was associated with the
write-off of inventory. These expenses appear in the accompanying year ended
December 31, 1999 income statement as $30.1 million in the special charge line
item and $2.0 million in the cost of services line item. During the fourth
quarter of 1999, we incurred $3.0 million for terminating leases, $5.8 million
for the severance of 76 telemarketing employees and 104 other staff employees
and $6.6 million for asset write downs including inventory. As of December 31,
1999 the reserve balance was $16.7 million, of which $10.1 million is for
terminating leases and $6.6 million is for severance payments to be paid out
primarily to former employees who have already been severed, during the first
three quarters of 2000 in accordance with local country requirements.

5. CONCENTRATION OF CREDIT RISK

     We are subject to significant concentrations of credit risk which consist
principally of trade accounts receivable, cash and cash equivalents, and
marketable securities. Our U.S. subsidiaries sell a significant portion of their
services to other carriers and, as a result, maintain significant receivable
balances with certain carriers. If the financial condition and operations of
these customers deteriorate below critical levels, our operating results could
be adversely affected.

     We maintain our cash with high quality credit institutions, and our cash
equivalents and marketable securities are in high quality securities.

$41,840,000, respectively. Gross gains (losses) of $(2,000), $(367,000) and
$11,000 were realized on these sales for the years ended December 31, 1997, 1998
and 1999.

7. INCOME TAXES

     We have incurred consolidated losses since inception for both book and tax
purposes. Several of our subsidiaries which are profitable have recorded income
tax expense in the aggregate of approximately $401,000, $1,334,000 and
$3,341,000 for the years ended December 31, 1997, 1998 and 1999, respectively.
As of December 31, 1997, 1998 and 1999, we had net operating loss carryforwards
generated primarily in the United States and the United Kingdom of approximately
$148 million, $367 million and $725 million, respectively. The net operating
loss carryforwards will expire at various dates beginning in 2010 through 2014
if not utilized. The utilization of the net operating loss carryforwards is
subject to certain limitations.

     In accordance with SFAS No. 109, we have computed the components of
deferred income taxes as of December 31, 1998 and 1999 as follows (in

assets is not assured.

8. NOTES PAYABLE AND LONG-TERM DEBT

  Senior Notes

     On October 3, 1996, RSL Communications PLC ("RSL PLC"), a wholly-owned
subsidiary of RSL Communications, Ltd. (apart from its subsidiaries, the
"Guarantor"), issued (the "Debt Offering") 300,000 Units, each consisting of an
aggregate of one $1,000 Senior Note (collectively, the "1996 Notes") due 2006
bearing interest at the rate of 12 1/4% and one warrant to purchase 3.975 Class
A common shares which expire in ten years (collectively, the "Warrants"). The
exercise price of such Warrants is $0.00457.

     The value ascribed to the Warrants was $4,000,000. The unamortized discount
is recorded as a reduction against the face value of the 1996 Notes, and is
amortized over the life of the 1996 Notes.

     Such unamortized discount was $1,783,000 and $1,553,000 at December 31,
1998 and December 31, 1999, respectively.

     The 1996 Notes, which are guaranteed by the Guarantor, are redeemable, at
RSL PLC's option, subsequent to November 15, 2001, initially at 106.1250% of
their principal amount, declining to 103.0625% of their

principal amount for the calendar year subsequent to November 15, 2002, and at
100% of their principal amount subsequent to November 15, 2003. The 1996 Notes,
or a portion thereof, may also be redeemed upon the consummation of a public
equity offering which yields proceeds in excess of a specified amount.

     In April 1998, we used approximately $101.0 million of the net proceeds
from our initial public offering of shares of Class A Common Stock (the "IPO")
in 1997 to redeem (the "Equity Clawback") $90.0 million of the 1996 Notes at a
premium of $11.0 million, as permitted under the 1996 Indenture. In April 1998,
we used approximately $43.1 million to redeem (the "Buyback") $37.5 million of
the 1996 Notes at a premium of $5.6 million, as permitted under the 1996
Indenture. The redemption premiums, and part of the discount and offering costs
were expensed in the amount of $20.8 million in the second quarter of 1998 as an
extraordinary item.

     In connection with the issuance of the 1996 Notes, we were required to
maintain restricted marketable securities in order to make the first six
scheduled interest payments on the 1996 Notes. Such restriction was ended with
the sixth semi--annual payment made in November 1999 and the securities matured.

     On February 27, 1998, RSL PLC completed concurrent offerings (the "1998
U.S. Offerings") of $200.0 million principal amount of 9 1/8% Senior Notes due
2008 and $328.1 million principal amount at maturity ($200.0 million initial
accreted value) of 10 1/8% Senior Discount Notes due 2008 (together, the "1998
U.S. Notes"). The 1998 U.S. Offerings generated gross proceeds to us of $400.0
million. On March 16, 1998, RSL PLC completed an offering (the "1998 DM
Offering," and together with the 1998 U.S. Offerings, the "1998 Offerings") of
182.0 million Deutsche mark denominated 10% Senior Discount Notes due 2008 (the
"1998 DM Notes," and together with the 1998 U.S. Notes, the "1998 Notes"). The
1998 DM Offering generated gross proceeds to us of $99.0 million.

     In November 1998, RSL PLC issued (the "12% Notes Offering") $100 million
aggregate principal amount at maturity of 12% Senior Notes due 2008 (the "12%
Notes"). The 12% Notes generated gross proceeds to us of approximately $94.5
million.

     In December 1998, RSL PLC issued (the "10 1/2% Notes Offering" and,
together with the 12% Notes Offering, the "New Notes Offerings") $200 million
aggregate principal amount of 10 1/2% Senior Notes due 2008 (the "10 1/2% Notes"
and, together with the 12% Notes, the "New Notes"). The 10 1/2% Notes generated
gross proceeds to us of approximately $198.5 million.

     In May, 1999 RSL PLC issued (the "9 7/8% Notes Offering") $175 million
aggregate principal amount at maturity of 9 7/8% Senior Notes due 2009. The
9 7/8% Notes generated gross proceeds to us of approximately $170.8 million.

     In September, 1999, pursuant to a consent solicitation, we obtained the
consent of holders of our outstanding debt and amended our indentures governing
our debt. These amendments were to permit the issuance and sale of capital stock
of deltathree.com and our Australian subsidiary in public or private
transactions without restricting the use of proceeds solely to investments in
telecommunications assets. In connection with the consent solicitation, total
fees paid were approximately $6.8 million. We recorded these fees as a reduction
in paid in capital received by deltathree.com in connection with its initial
public offering.

     In connection with the New 1998 Notes Offerings, RSL PLC entered into
registration rights agreements for the benefit of the holders of the New Notes
(the "New Notes Registration Rights Agreements"), pursuant to which RSL PLC
agreed to offer to exchange the New Notes for substantially identical notes
registered under the Securities Act. In February and March of 1999, in
accordance with the New Notes Registration Rights Agreements, RSL and RSL PLC
offered for exchange the New Notes for substantially identical notes registered
under the Securities Act. The Company's Registration Statement on Form S-4
(Registration No. 333-70023) filed with the Commission with respect to such
offering was declared effective by the Commission on January 26, 1999.

8. NOTES PAYABLE AND LONG-TERM DEBT--(CONTINUED)

     The 1996 Notes, the 1998 Notes, the New 1998 Notes and the 1999 Notes are
collectively referred to herein as the "Notes." The Notes are fully and
unconditionally guaranteed as to payment of principal, interest and any other
amounts thereof by us and RSL COM U.S.A.

     The indentures pursuant to which the Notes were issued contains certain
restrictive covenants which impose limitations on RSL and certain of its
subsidiaries ability to, among other things: (i) incur additional indebtedness,
(ii) pay dividends or make certain other distributions, (iii) issue capital
stock of certain subsidiaries, (iv) guarantee debt, (v) enter into transactions
with shareholders and affiliates, (vi) create liens, (vii) enter into
sale-leaseback transactions, and (viii) sell assets. Notwithstanding the
foregoing, these indentures do not impose restrictions on our ability to obtain
funds by dividends or loans from our subsidiaries.

     At December 31, 1998 and 1999, we were in compliance with the above
restrictive covenants.

  Credit Facilities

     Through LDM, we have a $10.0 million revolving credit facility all of which
was available at December 31,1999. This facility accrues interest at the prime
rate plus 2.5% per annum.

     At December 31, 1999, Telegate had $26 million of revolving credit
facilities with various banks that accrue interest at a rate of 6.0%, all of
which was available.

     Through RSL COM Canada, we have a $6.9 million revolving credit facility of
which $5.3 million was used for the lease of telecommunications equipment. The
lease terms provide for monthly payments through February 2006 at an interest
rate of 8.7% per annum.

  Vendor Financing

     One of our primary equipment vendors has provided some of our subsidiaries
approximately $85 million in vendor financing to fund the purchase of additional
switching and related telecommunications capital equipment. At December 31,
1999, all available amounts were utilized under this facility. Borrowings from
this equipment vendor accrue interest at a rate of LIBOR, plus 3.50% to 5.25% or
STIBOR plus 3.50% depending on the equipment purchased and whether the loan is
guaranteed by the Swedish Export Credits Guarantee Board. We repaid
approximately $30 million of the outstanding balance by the end of the first
quarter of 2000.

     At December 31, 1999, the Notes had a fair value of approximately $1,099
million. The decline in the fair value is primarily due to changes in the
interest rate environment. The remainder of our long-term debt had fair values
which approximated their carrying amounts.

     Interest expense on the above notes was approximately $37,136,000,
$70,860,000 and $118,379,000 for the years ended December 31, 1997, 1998 and

10. SHAREHOLDERS' EQUITY

  Common Stock

     On September 30, 1997, we revised our capital structure (the
"Recapitalization"), in part to (i) effect a 2.19-for-one stock split for each
outstanding share of each class of common shares and each outstanding share of
Preferred Stock, (ii) increase the number of authorized shares of its Class A
Common Stock and Class B Common Stock to an aggregate of 438,000,000 shares and
(iii) increase the number of authorized shares of its Preferred Stock to
65,700,000. The holders of the Class A Common Stock are entitled to one vote per
share, and the holders of the Class B Common Stock are entitled to ten votes per
share. During 1998, 4,515,411 shares were converted from Class B Common Stock in
exchange for Class A Common Stock.

     On September 30, 1997, we commenced an initial public offering of 8,280,000
shares of its Class A Shares. The aggregate offering price of the 8,280,000
shares of Class A Common Stock sold in the equity offering to the public was
$182,160,000 (at $22.00 per share), with net proceeds to us of $167,542,000.

     On November 30, 1998, we commenced a secondary public offering of 7,544,278
shares of its Class A Shares. The aggregate offering price of the 7,544,278
shares of Class A Common Stock sold in the equity offering to the public was
$180,120,000 (at $23.875 per share), with net proceeds to us of $169,989,000.

     In June 1997, RSL North America's founder and former Chairman elected to
exchange his shares in RSL North America, a subsidiary of the Company, for
shares in the Company. Accordingly, we issued 1,457,094 of the Class A Common
Stock, par value $0.00457 per share, of the Company in exchange for 15,619
shares of common stock of RSL North America and recorded approximately
$32,575,000 as additional paid in capital and an equal amount as goodwill.

     In March 1998, we registered 1,152,715 shares of Class A Common Stock to be
issued pursuant to the terms of the warrant agreement governing the Warrants
(the "Warrant Registration") and 300,000 shares of Class A Common Stock to be
sold by a corporation wholly owned by a former Vice Chairman of the Company, and
members of his family (the "Selling Shareholder") (which necessarily assumes the
conversion by the Selling Shareholder of an identical number of shares of Class
B Common Stock). The Warrant Registration was required pursuant to a
registration rights agreement entered into in connection with the private
offering (the "1996 Units Offering") of 300,000 units (the "Units") each
consisting of (i) $1,000 principal amount of 12 1/4% Senior Notes due 2006 and
(ii) one warrant to purchase 3.975 shares of Class A Common Stock of RSL (each a
"Warrant"). During 1997, 1998 an 1999 we issued 39,740, 242,943 and 179,445
shares of Class A Common Stock upon the exercise of warrants, respectively.

10. SHAREHOLDERS' EQUITY--(CONTINUED)

     In connection with the marketing and distribution services agreement
entered into with Metro Holding in June 1998, as mentioned in Note 2, we issued
1,607,142 shares of Class A Common Stock.

     During 1998 and 1999, we issued 1,232,339 and 798,475 shares of Class A
Common Stock upon the exercise of options, respectively. In addition, we issued
54,750 shares in both 1998 and in 1999 of Class A Common Stock upon the vesting
of restricted stock.

     During 1998 and 1999, in connection with the acquisition of certain
minority interests, we issued 428,272 and 1,492,314 shares of Class A Common
Stock, respectively.

  Preferred Stock

     During 1995, we issued 9,243,866 shares of our preferred stock to the
holders of our Class B Common Stock for cash of $13,354,000. The preferred stock
ranked senior to our common stock as to dividends and a liquidation preference
of $1.00 per share. Each share was convertible at the holder's option into 2.19
shares of Class B Common Stock. All preferred shares were automatically
converted into our Class B Common Stock in 1997 as the public offering yielded
proceeds in excess of $25,000,000, in accordance with the terms of the Preferred
Stock agreement. Dividends, at the rate of 8%, were cumulative. Upon conversion
of the shares of the preferred stock, the cumulative dividends were deemed to be
canceled and waived upon conversion. The cumulative amount of such dividends was
approximately $16,000. As of December 31, 1998 and 1999, there was no preferred
stock outstanding.

12. RELATED PARTY TRANSACTIONS

     During 1999 RSL Management Corporation ("RSL Management"), which is wholly
owned by Ronald S. Lauder, the Chairman of the Board of the Company and our
principal shareholder, sublet an aggregate of 7,500 square feet of office space
to us at an annual rent of $591,000 per annum. RSL Management sublet such space

of Estee Lauder and Leonard A. Lauder, a director of the Company, is the
Chairman of the Board of Directors of Estee Lauder. Fred Langhammer, a director,
is the President and Chief Executive Officer of Estee Lauder. This sublease
agreement was terminated without penalty on March 31, 2000. In addition, RSL
Management provides payroll and benefit services to the Company for an annual
fee of $6,000, $9,000 and $12,000 for the years ended December 31, 1997, 1998
and 1999, respectively.

     We have employment contracts with certain of our executive officers. These
agreements expire beginning December 2000 through January, 2003 unless
terminated earlier by the executive or by us, and provide for annual salaries,
and bonuses based on our performance. Salary expense for executive officers was
approximately $1.6 million, $2.1 million and $2.3 million for the years ended
December 31, 1997, 1998 and 1999, respectively. The aggregate commitment for
annual future salaries pursuant to the employment agreements at December 31,
1999, excluding bonuses, is approximately $2.1 million, $2.2 million and $2.3
million for 2000, 2001 and 2002, respectively.

13. EMPLOYEE BENEFIT PLANS

     In 1996, we instituted a defined 401(k) contribution plan which provides
retirement benefits for most of our U.S. employees. Our contributions to the
defined contribution plan, which are based on a percentage of the employee's
annual compensation subject to certain limitations, were not significant for the
years ended December 31, 1997, 1998 and 1999. Our subsidiary, Telegate,
established a defined benefit pension plan covering the members of Telegate's
board of directors effective December 31, 1998. Telegate did not make any
contributions to the plan nor did the plan pay any benefits in the year ended
December 31, 1999.

14. STOCK OPTION PLANS

  1995 Stock Option Plan

     In April 1995, we established an Incentive Stock Option Plan (as amended
and restated, the "1995 Plan") to reward employees, nonemployee consultants and
directors for service to us and to provide incentives for future service and
enhancement of shareholder value. The 1995 Plan is administered by the
Compensation Committee of our Board of Directors (the "Committee"). The
Committee consists of three members of the Board of Directors. The Plan provides
for awards of up to 2,847,000 shares of our Class A Common Stock.

     The options granted under the 1995 Plan terminate on the tenth anniversary
of the date of grant. As of December 31, 1999 a total of 2,716,617 options have
been granted of which 444,868 were outstanding (and 327,703 were outstanding and
exercisable) under this plan. In connection with the initial public offering of
our Class A Common Shares in 1997, this plan was replaced by our other existing
plans. We will not grant further options under the 1995 Plan.

  1997 Stock Incentive Plan

     The 1997 Stock Incentive Plan (the "1997 Stock Plan") was adopted in
conjunction with the initial public offering of our Class A common shares in
1997 to attract, retain and motivate our key employees. The 1997 Stock Plan is
administered by the Committee. The 1997 Stock Plan provides for the grant of the
incentive and non-incentive stock options, stock appreciation rights, restricted
stock, and various combinations thereof. The maximum number of shares of
Class A Common Stock available under the 1997 Stock Plan is 8,100,000, with no
more than 500,000 options or stock appreciation rights to be granted to any one
participant in a calendar year. In March, 1999 the Committee determined that
with respect to awards previously granted and awards granted in the future, in
the event of a change in control, 100% of the awards granted will immediately
become fully vested and excercisable or, at the Committee's sole discretion, the
award may be exchanged for a payment to a participant in cash of an amount equal
to the excess of the change in control price over the exercise price for the
award, provided certain conditions are met. The options vest over a three-year
period and terminate on the seventh

anniversary of the date of grant, unless a different vesting schedule is
designated by the Committee. As of December 31, 1999, a total of 4,605,617
options and 164,250 shares of restricted stock have been granted under this
plan.

  1997 Performance Incentive Compensation Plan

     During 1997, we established the 1997 Performance Incentive Compensation
Plan (the "1997 Performance Plan") to reward employees for superior performance.
The 1997 Performance Plan is effective through and including the year 2000,
unless extended or earlier terminated by the Board of Directors. Awards under
the 1997 Performance Plan may be made to key employees recommended by the Chief
Executive Officer, selected by the Committee and approved by the Board of
Directors, and may be paid in cash, in shares of Class A Common Stock or in any
combination thereof, provided that at least 50% of such award is required to be
paid in cash. The 1997 Performance Plan provides for the grant of up to 400,000
shares of Class A Common Stock. No shares have been granted under the 1997
Performance Plan.

  1997 Directors' Compensation Plan

     During 1997, we adopted the 1997 Directors' Compensation Plan (the "1997
Directors' Plan"). Under the 1997 Directors' Plan, each non-employee Director
will be granted options annually to acquire a number of Class A Common Stock
with an aggregate fair market value on the date of grant equal to $50,000,
except for the Chairman and the Vice Chairman of the Board, whose grants have a
fair market value of $150,000 and $75,000, respectively. The 1997 Directors'
Plan provides for the grant of up to 250,000 shares of Class A Common Stock. The
options have a ten-year term and vest over a five-year period, subject to
certain acceleration provisions. A total of 103,365 options have been granted
under this plan.

     The exercise price of stock options granted under the 1997 Stock Plan, the
1997 Performance Plan and the 1997 Directors' Plan (collectively, the "1997
Plans") will equal the fair market value of the Class A Common Stock on the date
of the grant. We record stock option grants under the 1997 Plans based on the
fair market value of the underlying security on the date of grant. We used the
expected life of the underlying security to calculate the fair market value of
such security.

     At December 31, 1999, we have authorized and reserved the following amounts
for future grants: approximately 3,514,842 shares of Class A Common Stock under
the 1997 Stock Plan, 400,000 under the 1997 Performance Plan and 150,044 under
the 1997 Directors' Plan.

     SFAS Statement No. 123, "Accounting for Stock Based Compensation" ("SFAS
No. 123") was issued by the FASB in 1995 and if fully adopted, changes the
methods for recognition of costs on plans similar to those we have. Adoption of
the recognition provisions of SFAS No. 123 is optional; however, pro forma
disclosures as if we adopted the cost recognition requirements under SFAS No.
123 are presented below.

     Under SFAS No. 123, for options granted, the fair value at the date of
grant was estimated using the Black-Scholes option pricing model. The fair value
was estimated using the minimum value method. Under this method, a volatility
factor of approximately 0.7 was used for options granted on or after the date of
the initial public offering and the minimum value method was used for options
granted prior to the date of the initial public offering, as there was no market
for our common stock in which to measure the stock price volatility.

     The following weighted average assumptions were used in calculating the
fair value of the options granted in the years ended December 31, 1997, 1998 and
1999, respectively: risk-free interest rates between 4.54% and 5.95%; no
dividends are expected to be declared; expected life of the options are between
39 and 51 months, between 18 and 42 months and between 18 and 42 months,
respectively; and a maximum contractual life of 10 years.

     For purposes of the pro forma disclosures, the estimated fair value of the

     We also granted restricted units ("Restricted Units") under the 1997 Stock
Plan. All grants of Class A Common Stock and Restricted Units vest over a
three-year period and were made at the fair market value on the date of grant.
Restricted Units granted under the 1997 Plan to certain employees generally are
convertible into shares of Class A Common Stock or cash, at our discretion.

     As of December 31, 1999, the approximate total number of shares of Class A
Common Stock into which all outstanding Restricted Units may be converted, based
on the valuations attributed to our subsidiaries is estimated to be
approximately 1,099,000. As of December 31, 1999, vested and exercisable
Restricted Units which may be converted, based on the valuations attributed to
the Company's subsidiaries is estimated to be 447,000 at a weighted average
exercise price of $2.47 per share.

     Upon completion of deltathree.com's initial public offering, shares of its
Class A common stock were issued in exchange for vested restricted units on a
one-for-one basis upon payment of the related exercise price. In addition,
options were issued to purchase shares of deltathree.com's Class A common stock
in exchange for unvested restricted units on a one-for-one basis, with the same
exercise prices and vesting schedules as the corresponding restricted units.
Pursuant to generally accepted accounting principles, the restricted units were
considered variable grants. Consequently, the changes in the fair value of the
underlying shares at each balance date affected the aggregate amount of deferred
compensation recorded by deltathree.com and by us.

     In April 1999, deltathree.com granted options to purchase an aggregate of
1.1 million shares of its common stock to executive officers of deltathree.com,
subject to completion of its initial public offering. Such options vest over a
three-year period from the date of grant and are exercisable for a period of
seven years from the date of grant. We recorded deferred compensation expense of
$23.6 million in 1999 primarily related to the deltathree.com restricted units
and options. As of December 31, 1999 $8.3 million was deferred and is included
as a reduction of stockholders' equity and is being amortized by charges to
operations over the three-year vesting period.

     In addition, in November 1999, deltathree.com adopted the 1999 Stock
Incentive Plan ("the Plan"). Under the Plan, 4,000,000 shares were reserved for
issuance upon the exercise of awards to be granted. In addition,
deltathree.com's compensation committee may grant both incentive and
non-incentive stock options for common stock of deltathree.com. The options
generally have a term of seven years and become exercisable in three equal
installments commencing on the first anniversary of the date of the grant. The
purchase price per share payable upon exercise of an option is no less than the
fair market value of the share at the date of grant. As of December 31, 1999,
options to purchase 502,800 shares of deltathree.com were outstanding with
exercise prices of $15 and $25 per share.

     We recorded expenses in connection with such commitments for the years
ended December 31, 1997, 1998 and 1999 of approximately $9,100,000, $81,997,000
and $141,781,000 respectively.

     Commitments and Contingencies--On October 8, 1999, Aerotel, Ltd. and
Aerotel U.S.A. commenced a suit against us, deltathree.com and one of our U.S.
subsidiaries in the United States District Court for the Southern District of
New York. Aerotel alleges that we are infringing on a patent issued to Aerotel
in November 1987 by making, using, selling and offering for sale prepaid
telephone card products in the United States. Aerotel seeks an injunction to
stop us from using technology covered by this patent, monetary damages in an
unspecified amount and reimbursement of attorneys' fees. We have answered the
complaint and the parties are currently engaged in pre-trial discovery. As we
continue to evaluate these claims, we believe that we have meritorious defenses
to the claims and intend to defend the lawsuit vigorously. However, the outcome
of the litigation is inherently unpredictable and an unfavorable result may have
a material adverse effect on us. Regardless of the ultimate outcome, the
litigation could result in substantial expenses to us and significant diversion
of efforts by our managerial and other personnel.

     We are, from time to time, a party to litigation that arises in the normal
course of our business operations. Except as previously described, we are not
presently a party to any litigation that we believe could reasonably be expected
to have a material adverse effect on our business or results of operations.

     We are involved in various claims that arose in the ordinary course of our
businesses. The expected settlements from certain of these matters have been
accrued and are recorded as Other Liabilities. In our opinion,

the settlement of such claims would not have a material adverse effect on our
consolidated financial position or results of our operations.

     In connection with the acquisition of one of our United States
subsidiaries, we recorded what we believed to be our best estimate of the
unfavorable portion related to certain transmission capacity agreements. During
1997, we successfully amended such transmission capacity agreements. The
resulting settlement of approximately $7,000,000 was recorded as Other
Income--Net in the statements of operations and comprehensive loss.

     We are a party to separate stockholder agreements with certain minority
stockholders of our subsidiaries, pursuant to which we have granted put rights
with roll-up right provisions ("put rights"). These agreements restrict the sale
of the minority stockholders' interest to any person or entity other than us and
in certain cases require us to purchase these interests in certain of our
subsidiaries. Certain of the minority stockholders have the option to require us
to purchase their interests at any time in exchange for cash or Class A Common
Stock (in most instances, at our sole discretion) and have the right to require
us to purchase their interests in whole or in part at various times through
December 31, 2005 or upon cessation of such stockholder's employment with us for
any reason. Generally, the minority stockholder remains employed by us and
receives a salary and a performance based bonus. We have issued put rights to
substantially all of our subsidiaries' minority stockholders at the time we
acquired a majority shareholding in the entity acquired or formed. Such put
rights were issued to create an incentive for our minority shareholders to
maximize the long term value of their respective subsidiaries and to provide
liquidity to the shareholders at the time of exercise.

     Our issuance of put rights did not at the time of grant provide the
recipient of such rights with any tangible value other than the right to put
their minority shares to us, in a value for value exchange (fair value of the
minority shares of the subsidiary for fair value of Class A Common Stock or
cash), in most instances, at our sole discretion. Solely for the purpose of
illustration, if all such options were in effect on December 31, 1999, our
aggregate purchase obligation is estimated to be approximately $50.3 million at
that date.

16. SIGNIFICANT CUSTOMER

     For the years ended December 31, 1997, 1998 and 1999 no customer accounted
for more than 10% of our revenues.

17. SEGMENT REPORTING AND GEOGRAPHIC INFORMATION

  General Information

     We have four reportable segments: three regional segments in, Europe, North
America and Asia/Pacific and other operations (which include immaterial
operations in Latin America) and deltathree.com, our global internet telephony
subsidiary. Revenues from deltathree.com have been immaterial to us. However
with the proceeds of deltathree.com's initial public offering in November 1999,
it will incur significant marketing and infrastructure costs as it executes its
expansion plans. The Company's three regional segments are strategic business
units that offer primarily identical products and services. They are managed
separately because each business within the regions is naturally aligned to its
geographic neighbors. Similar operating segments that operate in different
countries are managed separately, and, in accordance with the provisions of SFAS
131, we have aggregated similar operating segments into the three regional
segments.

     (a) Information about Operating Profit or Loss and Total Assets

     The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. We evaluate performance based on
the profit or loss from operations.

17. SEGMENT REPORTING AND GEOGRAPHIC INFORMATION--(CONTINUED)

     We account for inter-segment sales and transfers as if the sales or
transfers were inter-company and accordingly, no profit or loss is included
among the segments. We do not systematically allocate assets or a proportionate
allocation of indebtedness to the divisions of the subsidiaries constituting our
consolidated group.

     General corporate expenses are included within selling, general and
administrative expenses in the statements of operations and comprehensive loss.

     The following table provides certain segment data on our operations for the
years ended December 31, 1997, 1998 and 1999 (in thousands).

19. SUBSEQUENT EVENT

     In February, 2000 we issued 2.3 million Series A Cumulative Convertible
Preferred Shares (preferred shares) at a price of $50 per share, and received
net proceeds of $111.0 million. The preferred shares are convertible at any time
by the holders into our Class A Common shares at a conversion rate of 2.2584
shares for each preferred share subject to adjustments under certain
circumstances. Dividends accrue at the rate of 7 1/2 % per year and are payable
quarterly. Beginning in February, 2005 we will have the right to redeem some or
all of the preferred shares at a predetermined redemption price plus accrued
dividends, if any. We will be required to

redeem any preferred shares still outstanding on February 1, 2012 at a
redemption price of $50 per share plus accrued dividends. Holders of the
preferred shares are generally not entitled to any voting rights. The preferred
shares, which have a liquidation value of $50 per share, rank junior to all of
our existing and future debts and obligations.

     Concurrent with the issuance of the preferred shares, RSL PLC issued
$100 million and 100 million Euro-denominated Senior Notes due 2010 (the "2000
Notes"). The notes, which are guaranteed by us and by RSL COM U.S.A., a wholly
owned subsidiary of RSL PLC, bear interest at an annual rate of 12 7/8 %. The
debt issuances generated combined proceeds to us of approximately $192.2
million. In connection with the guarantee of the 2000 Notes, RSL COM U.S.A. also
became a guarantor of RSL PLC's previously issued and outstanding Notes.

The following presents summarized financial information of RSL COM U.S.A. as of
December 31, 1998 and 1999 and for the years ended December 31, 1997, 1998 and

relation to any of the affairs of the Registrant and every one of them, and
their heirs, executors and administrators, shall be indemnified and secured
harmless out of the assets of the Registrant from and against all actions,
costs, charges, losses, damages and expenses which they or any of them, their
heirs, executors or administrators, shall or may incur or sustain by or by
reason of any act done, concurred in or omitted in or about the execution of
their duty, or supposed duty, or in their respective offices or trusts, and none
of them shall be answerable for the acts, receipts, neglects or defaults of the
others of them or for joining in any receipts for the sake of conformity, or for
any bankers or other persons with whom any moneys or effects belonging to the
Registrant shall or may be lodged or deposited for safe custody, or for
insufficiency or deficiency of any security upon which any moneys of or
belonging to the Registrant shall be placed out on or invested, or for any other
loss, misfortune or damage which may happen in the execution of their respective
offices or trusts, or in relation thereto, provided that this indemnity shall
not extend to any matter in respect of any fraud or dishonesty which may attach

ITEM 22. UNDERTAKINGS

     (1) The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrants' annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (2) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that, in the opinion of the Commission, such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     (3) The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (4) The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

    A duly executed proxy shall be irrevocable if it states that it is
irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power. A proxy may be made
irrevocable regardless of whether the interest with which it is coupled is an
interest in the stock itself or an interest in the corporation generally. All
proxies shall be filed with the Secretary of the meeting before being voted
upon.

Global Notes and, as holder of the Global Notes, the Book-Entry Depositary
promptly shall cause such consents or waivers to be granted and such action to
be taken with respect to the Global Notes as DTC, Euroclear or Clearstream had
given or had taken.

                  (b) As soon as practicable after receipt by the Book-Entry
Depositary of an Offer to Purchase with respect to the Global Notes, the
Book-Entry Depositary shall mail to DTC, Euroclear and Clearstream a notice
containing (i) such information as is contained in such notice, (ii) a statement
that the holders of Depositary Interests at the close of business on a specified
record date (established in accordance with Section 2.8 hereof) will be
entitled, subject to the provisions of or governing the Depositary Interests, to
elect to have all or any portion of their interest in the Global Notes
repurchased in accordance with such Offer to Purchase and (iii) such
documentation provided by the Issuer as is necessary for DTC, Euroclear or
Clearstream, as applicable, to elect to have all or any portion of the
Depositary Interests repurchased pursuant to such Offer to Purchase. In the case
of the Dollar Notes, so long as DTC or its nominee own Depositary Interests,
such notice to DTC or its nominee shall also comply with the Letter of
Representations. In the case of the Euro Notes, so long as Euroclear and
Clearstream own Depositary Interests (through the Common Depositary), such
notice to

                                      xiv

<PAGE>

Euroclear and Clearstream shall also comply with the applicable rules and
procedures of Euroclear and Clearstream. Upon receipt of elections relating to
such Offer to Purchase from DTC, Euroclear or Clearstream, as applicable,
received on or before the date established by the Issuer for such purpose, the
Book-Entry Depositary shall endeavor insofar as practicable and permitted under
the provisions of or governing the Depositary Interests and the Global Notes to
tender the Global Notes or portions thereof requested to be tendered by DTC,
Euroclear or Clearstream, as applicable, for repurchase in accordance with such
Offer to Purchase. The Book-Entry Depositary shall not itself exercise any
discretion in the tender of any Global Notes pursuant to an Offer to Purchase.

                  (c) As soon as practicable after receipt by the Book-Entry
Depositary of any notice of redemption with respect to the Global Notes pursuant
to Section 11.01 of the Indentures, the Book-Entry Depositary shall mail to DTC,
Euroclear and Clearstream a notice containing (i) such information as is
contained in such notice and (ii) a statement that Notes called for redemption
must be surrendered to the Paying Agent in order to collect the Redemption
Price. In the case of the Dollar Notes, so long as DTC or its nominee own
Depositary Interests, such notice shall also comply with the Letter of
Representations. In the case of the Euro Notes, so long as Euroclear and
Clearstream own Depositary Interests (through the Common Depositary) such notice
shall also comply with the applicable rules and procedures of Euroclear and
Clearstream.

                  (d) DTC, Euroclear and Clearstream may direct in writing the
time, method and place of conducting any proceeding for any remedy available to
the Book-Entry Depositary with respect to the Global Notes or exercising any
power conferred on the Book-Entry Depositary. However, the Book-Entry Depositary
may refuse to follow any direction that conflicts with law, the Indentures or
this Agreement, that may involve the Book-Entry Depositary in personal
liability, or that the Book-Entry Depositary determines in good faith may be
unduly prejudicial to the rights of the holders of Book-Entry Notes not joining
in the giving of such direction and may take any other action it deems proper
that is not inconsistent with any directions received from DTC, Euroclear or
Clearstream pursuant to this Section 2.9(d).

                  SECTION 2.10 Changes Affecting the Global Notes. Upon any
reclassification of the Global Notes, or upon any recapitalization,
reorganization, merger or consolidation or sale of assets affecting the Issuer
or to which the Issuer is a party, any securities that shall be received by the

                                       xv
<PAGE>

Book-Entry Depositary in exchange for or in respect of a Global Note shall be
treated as a new Global Note under this Agreement and any corresponding
Depositary Interests shall thenceforth represent such new securities so
received; provided, however, that any security issued in exchange for or in
respect of a Global Note under such circumstances shall not be deemed to be a
new security if the Issuer delivers to the Book-Entry Depositary an Opinion of
Counsel, to the effect that the recapitalization, reorganization, merger or
consolidation or sale of assets, as appropriate, did not result in the creation
of a security materially different from that represented by such Global Note.

                  SECTION 2.11 Surrender of the Global Notes. In the event of
the redemption, payment or purchase in full of all the Notes represented by any
of the Global Notes, then the applicable Depositary Interest and the applicable
Global Note shall become void and the Book-Entry Depositary shall surrender such
Global Note to the Trustee for cancellation. In the event of a partial
redemption of the Notes represented by a Global Note, the Book-Entry Depositary
shall comply with the requirements of Section 2.7 hereof.

                  SECTION 2.12 Reports. The Book-Entry Depositary shall promptly
send to DTC, Euroclear and Clearstream any notices, reports and other
communications received from the Issuer that are received by the Book-Entry
Depositary as holder of the Global Notes.

                            THE BOOK-ENTRY DEPOSITARY

                  SECTION 3.1 Certain Duties and Responsibilities. (a) The
Book-Entry Depositary undertakes to perform such duties and only such duties as
are specifically set forth in this Agreement.

                  (b) No provision of this Agreement shall be construed to
relieve the Book-Entry Depositary from liability for its own negligent action,
its own negligent failure to act, or its own bad faith or willful misconduct,
except that:

                  (1) the duties and obligations of the Book-Entry Depositary
         with respect to the Global Notes and the Depositary Interests shall be
         determined solely by the express provisions of this Agreement and
         neither the Book-Entry Depositary, nor its officers, directors,
         employees and agents shall be liable except for the performance of such
         duties and obligations as are specifically set forth in this Agreement,
         and no

                                      xvi

<PAGE>

         implied covenants or obligations shall be read into
         this Agreement against the Book-Entry Depositary; and

                  (2) in the absence of bad faith on its part, the Book-Entry
         Depositary 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 Book-Entry Depositary and
         conforming to the requirements of this Agreement, but in the case of
         any such certificates or opinions that by any provision hereof are
         specifically required to be furnished to the Book-Entry Depositary, the
         Book-Entry Depositary shall be under a duty to examine the same to
         determine whether or not they conform to the requirements of this
         Agreement.

                  (c) The Book-Entry Depositary shall not be liable for any
error of judgment made in good faith by a Responsible Officer of the Book-Entry
Depositary, unless it shall be proved that the Book-Entry Depositary was grossly
negligent in ascertaining the pertinent facts.

                  (d) The Book-Entry Depositary shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance
with the written direction of DTC, Euroclear or Clearstream pursuant to Section
2.9 hereof relating to the time, method and place of conducting any proceeding
for any remedy available to the Book-Entry Depositary, or exercising any power
conferred upon the Book-Entry Depositary, under this Agreement.

                  (e) No provision of this Agreement will require the Book-Entry
Depositary 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.

                  (f) Whether or not therein expressly so provided, every
provision of this Agreement relating to the conduct or affecting the liability
of or affording protection to the Book-Entry Depositary shall be subject to the
provisions of this Section.

                  (g) The Book-Entry Depositary owes no fiduciary duties to any
person by virtue of this Agreement except as expressly set forth herein.

                  SECTION 3.2 Notice of Default. The Book-Entry Depositary shall

the Global Notes of which

Services department has actual knowledge or (y) promptly after being notified of
an Event of Default by the Trustee, transmit by mail to DTC, Euroclear and
Clearstream in the manner provided in Section 5.2, notice of such Event of
Default, unless such Event of Default shall have been cured or waived.

                  SECTION 3.3 Certain Rights of Book-Entry Depositary. Subject
to the provisions of Section 3.1 hereof:

                  (a) the Book-Entry Depositary may conclusively rely and shall
be protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction,

document delivered to it in accordance with the terms of this Agreement and
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

the Issuer may be sufficiently evidenced by a Board Resolution;

                  (c) the Book-Entry Depositary may consult with counsel and the
advice of such counsel confirmed in writing or any Opinion of Counsel shall be
full and complete authorization and protection with respect to any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon in

                  (d) the Book-Entry Depositary shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order,
approval, appraisal, bond, debenture, note, coupon, security or other paper or
document, but the Book-Entry Depositary, may (but shall have no obligation to)
make reasonable further inquiry or investigation into such facts or matters
related to the issuance of the Global Notes and, if the Book-Entry Depositary
shall determine to make such further inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Issuer, at the
Issuer's expense, at reasonable times during normal business hours, personally
or by agent or attorney;

                  (e) the Book-Entry Depositary may execute any of the powers
hereunder or perform any duties hereunder either

<PAGE>

directly or by or through agents or attorneys and the Book-Entry Depositary
shall not be responsible for any misconduct or negligence on the part of any
such agent or attorney appointed with due care;

                  (f) the Book-Entry Depositary shall be under no obligation to
exercise any of the rights or powers vested in it by this Agreement at the
request, order or direction of DTC, Euroclear or Clearstream pursuant to this
Agreement, unless DTC, Euroclear or Clearstream shall have offered or caused to
be offered to the Book-Entry Depositary security or indemnity reasonably
satisfactory to it against the costs, expenses and liabilities that might be
incurred by it in compliance with such request or direction, provided that such
request, order or direction shall not expose the Book-Entry Depositary to
personal liability;

                  (g) the Book-Entry Depositary shall not be liable for any
action taken or omitted by it in good faith and reasonably believed by it to be
authorized or within the discretion, rights or powers conferred upon it by this
Agreement; and

                  (h) whenever in the administration of its duties under this
Agreement the Book-Entry Depositary shall deem it necessary or desirable that a
matter be proved or established prior to taking or suffering or omitting any
action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Book-Entry Depositary, be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Book-Entry
Depositary, and such certificate, in the absence of negligence or bad faith on
the part of the Book-Entry Depositary, shall be full warrant to the Book-Entry
Depositary for any action taken, suffered or omitted by it under the provisions
of the Agreement, upon the faith thereof.

                  SECTION 3.5 Not Responsible for Recitals or Issuance of Notes.
The recitals contained in the Indentures and in the Notes, except the Trustee's
certificates of authentication, shall be taken as the statements of the Issuer,
and the Book-Entry Depositary assumes no responsibility for their correctness.

sufficiency of the Indentures or of the Notes, (ii) the sufficiency of this
Agreement or (iii) the validity, with respect to the Issuer, of this Agreement.

                  SECTION 3.5 Money Held in Trust. Money held by the Book-Entry
Depositary in trust hereunder need not be segregated from other funds held by
the Book-Entry Depositary, except to the extent required by law. The Book-Entry
Depositary shall be under no obligation to invest or pay interest on any money
received by it hereunder, except as otherwise agreed in writing with the Issuer.
Any interest accrued on funds deposited with the Book-Entry Depositary under
this Agreement shall be paid to the Issuer from time to time and DTC shall have
no claim to any such interest.

                  SECTION 3.6 Compensation and Reimbursement. The Issuer and
Holdings, jointly and severally agree:

                  (a) to pay to the Book-Entry Depositary from time to time
reasonable compensation agreed in writing for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law with
regard to the compensation of a trustee of an express trust);

                  (b) except as otherwise expressly provided herein, to
reimburse the Book-Entry Depositary upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Book-Entry
Depositary in accordance with any provision of this Agreement (including the
reasonable compensation, expenses and disbursements of its agents and counsel),
except any such expense, disbursement or advance as may be attributable to its
negligence, bad faith or willful misconduct; and

                  (c) to indemnify the Book-Entry Depositary and its directors,
officers, agents and employees for, and to hold it harmless against, any loss,
liability or expense incurred without negligence, bad faith on its part, arising
out of or in connection with the acceptance or administration of this Agreement
and its duties hereunder, including the costs and expenses of defending itself
against or investigating any claim of liability in connection with the exercise
or performance of any of its powers or duties hereunder.

                  The obligations of the Issuer under this Section to compensate
and indemnify the Book-Entry Depositary and to pay or reimburse the Book-Entry
Depositary for reasonable expenses, disbursements and advances shall survive the
satisfaction and discharge of this Agreement or the earlier of the resignation
or the removal of the Book-Entry Depositary. Such obligations shall be a senior
claim to that of the Notes upon all property and funds held or collected by the
Book-Entry Depositary as such, except funds held in trust for the benefit of the
holders of the Notes.

                  SECTION 3.7 Book-Entry Depositary Required: Eligibility. At
all times when there is a Book-Entry Depositary hereunder, such Book-Entry
Depositary shall be a corporation organized and doing business under the laws of
the United States of America, any State thereof or the District of Columbia,
having, together with its parent, a combined capital and surplus of at least
$50,000,000, subject to supervision or examination by federal, state or District
of Columbia authority, willing to act on reasonable terms. Such corporation
shall have its principal place of business in the Borough of Manhattan, The City
of New York, if there be such a corporation in such location willing to act upon
reasonable and customary terms and conditions. If such corporation, or its
parent, publishes reports of condition at least annually, pursuant to law or to
the requirements of the aforesaid supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. The Book-Entry Depositary
shall have executed a letter of representations to DTC acceptable in form and
substance to DTC and the Issuer with respect to the Depositary Interests. The
Book-Entry Depositary hereunder shall at all times be the Trustee under the
Indentures, subject to receipt by the Issuer of an Opinion of Counsel that the
same Person is precluded by law from acting in such capacities. If at any time
the Book-Entry Depositary shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

                  SECTION 3.8 Resignation and Removal, Appointment of Successor.
(a) No resignation or removal of the Book-Entry Depositary and no appointment
of a successor Book-Entry Depositary pursuant to this Article shall become
effective until (i) the approval in writing of a successor Book-Entry Depositary
by the Issuer and the acceptance of the appointment by such successor Book-Entry
Depositary in accordance with the applicable requirements of Section 3.9 hereof
or (ii) the issuance of Registered Notes in accordance with Section 2.5 hereof
and the Indentures.

                  (b) The Book-Entry Depositary may resign all of its rights and
duties with respect to the Global Notes and the Depositary Interests by giving
written notice thereof to the Issuer, DTC, Euroclear and Clearstream in
accordance with Sections 5.1 and 5.2 hereof. The Book-Entry Depositary may be
removed at any time upon 30 days' notice by the filing with it of an instrument
in writing signed on behalf of the Issuer and specifying such removal and the
date when it is intended to become effective. If the instrument of acceptance by
a successor Book-Entry Depositary or the

                                      xxi
<PAGE>

approval by the Issuer required by Section 3.9 hereof shall not have been
delivered to the Book-Entry Depositary within 30 days after the giving of such
notice of resignation, the resigning Book-Entry Depositary may petition any
court of competent jurisdiction for the appointment of a successor Book-Entry
Depositary.

                  (c)  If at any time:

                  (1) the Book-Entry Depositary shall cease to be eligible under
         Section 3.7 hereof or shall cease to be eligible as Trustee under the
         Indentures, and shall fail to resign after written request therefor by
         the Issuer or DTC, Euroclear, and Clearstream, or

                  (2) the Book-Entry Depositary shall become incapable of acting
         with respect to the Global Notes and the Depositary Interests, or shall
         be adjudged bankrupt or insolvent, or a receiver or liquidator of the
         Book-Entry Depositary or its property shall be appointed or any public
         officer shall take charge or control of the Book-Entry Depositary or
         its property or affairs for the purpose of rehabilitation, conservation
         or liquidation,

then, in any such case, (i) the Issuer, by Board Resolution, may remove the
Book-Entry Depositary and appoint a successor Book-Entry Depositary and (ii) if
the Issuer does not remove the Book-Entry Depositary and appoint a successor
pursuant to clause (i), DTC, Euroclear, and Clearstream, upon the direction of
holders of at least a majority of the total aggregate principal amount of the
Book-Entry Notes outstanding, may petition any court of competent jurisdiction
for the removal of the Book-Entry Depositary with respect to the Global Notes
and the Depositary Interests and the appointment of a successor Book-Entry
Depositary or Book-Entry Depositaries unless Registered Notes have been issued
in accordance with the Indentures. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, remove the Book-Entry Depositary
with respect to the Global Notes and the Depositary Interests and appoint a
successor Book-Entry Depositary for the Global Notes and the Depositary
Interests.

                  (d) If the Book-Entry Depositary shall resign, be removed or
become incapable of acting, or if a vacancy shall occur in the office of
Book-Entry Depositary for any cause, the Issuer, by Board Resolution, shall
promptly appoint a successor Book-Entry Depositary (other than the Issuer) and
shall comply with the applicable requirements of Section 3.9 hereof. If no
successor Book-Entry Depositary with respect to the Notes shall have been so
appointed by the Issuer and

                                      xxii
<PAGE>

accepted appointment in the manner required by Section 3.9, DTC, Euroclear and
Clearstream, upon direction of holders of at least a majority of the total
aggregate principal amount of Book-Entry Notes outstanding, may petition any
court of competent jurisdiction for the appointment of a successor Book-Entry
Depositary unless Registered Notes have been issued in accordance with the
Indenture and Section 2.5 hereof.

                  (e) The Issuer shall give, or shall cause such successor
Book-Entry Depositary to give, notice of each resignation and each removal of a
Book-Entry Depositary and each appointment of a successor Book-Entry Depositary
to DTC, Euroclear and Clearstream in accordance with Section 5.2 hereof. Each
notice shall include the name of the successor Book-Entry Depositary and the
address of its Corporate Trust Office.

                  (f) If a Book-Entry Depositary hereunder shall resign, it
shall not be relieved of any responsibility for its actions or omissions
hereunder solely by virtue of such resignation.

                  SECTION 3.9 Acceptance of Appointment by Successor. (a) In
case of the appointment hereunder of a successor Book-Entry Depositary, every
such successor Book-Entry Depositary so appointed shall execute, acknowledge
and deliver to the Issuer and to the retiring Book-Entry Depositary an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Book-Entry Depositary shall become effective and such successor
Book-Entry Depositary, without any further act, deed or conveyance, shall become
vested with all the rights, powers, agencies and duties of the retiring
Book-Entry Depositary, with like effect as if originally named as Book-Entry
Depositary hereunder; but, on the request of the Issuer or the successor
Book-Entry Depositary, such retiring Book-Entry Depositary shall, upon payment
of all amounts due and payable to it pursuant to Section 3.6 hereof, execute and
deliver an instrument transferring to such successor Book-Entry Depositary all
the rights and powers of the retiring Book-Entry Depositary and shall duly
assign, transfer and deliver to such successor Book-Entry Depositary all
property and money held by such retiring Book-Entry Depositary hereunder. Any
retiring Book-Entry Depositary shall, nonetheless, retain a prior claim upon all
property or funds held or collected by such Book-Entry Depositary to secure any
amounts then due it pursuant to Section 3.6 hereof. The Book-Entry Depositary
will not be liable for any acts or omissions of any successor Book-Entry
Depositary appointed pursuant to Section 3.8 hereof.

                                     xxiii
<PAGE>

                  (b) Upon request of any such successor Book-Entry Depositary,
the Issuer shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Book-Entry Depositary all such
rights, powers and agencies referred to in paragraph (a) of this Section.

                  (c) No successor Book-Entry Depositary shall accept its
appointment unless at the time of such acceptance such successor Book-Entry
Depositary shall be eligible to serve as such under this Article.

                  (d) Upon acceptance of appointment by any successor Book-Entry
Depositary as provided in this Section, the Issuer shall give notice thereof to
DTC in accordance with Section 5.02 hereof. If the acceptance of appointment is
substantially contemporaneous with the resignation of the Book-Entry Depositary,
then the notice called for by the preceding sentence may be combined with the
notice called for by Section 3.8 hereof. If the Issuer fails to give such notice
within ten days after acceptance of appointment by the successor Book-Entry
Depositary, the successor Book-Entry Depositary shall cause such notice to be
given at the expense of the Issuer.

                  SECTION 3.10 Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Book-Entry Depositary 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 Book-Entry Depositary
shall be a party, or any corporation succeeding to all or substantially all the
agency business of the Book-Entry Depositary, shall be the successor of the
Book-Entry Depositary hereunder, without the execution or filing of any paper or
any further act on the part of any of the parties hereto; provided that such
corporation shall be otherwise eligible to serve as Book-Entry Depositary under
this Article.

                  SECTION 3.11 Compliance with Letter of Representations. As
long as DTC or its nominee is DTC, the Book-Entry Depositary shall comply with
all of its representations made to DTC in the Letter of Representations, and any
successor Book-Entry Depositary shall comply with all representations made to
DTC in a similar letter of representations in form and substance acceptable to
DTC and the Issuer.

<PAGE>


such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Issuer or the Guarantors. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein

instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01) conclusive in favor of the Trustee and the Issuer
and Parent Guarantor, if made in the manner provided in this Section.

                  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, the

such action is made upon such Security.

determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities; provided that the Issuer may not set a record date for,
and the provisions of this paragraph shall not apply with respect to, the giving
or making of any notice, declaration, request or direction referred to in the
next paragraph. If not set by


                                      -33-
<PAGE>


the Issuer prior to the first solicitation of a Holder made by any Person in
respect of any such matter referred to in the foregoing sentence, the record
date for any such matter shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 7.01)
prior to such first solicitation. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Securities on such record date, and no
other Holders, shall be entitled to take the relevant action, whether or not
such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount at maturity of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Issuer from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be canceled and of no effect), and nothing in this paragraph shall
be construed to render ineffective any action taken by Holders of the requisite
principal amount at maturity of Outstanding Securities on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Issuer, at its own expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Trustee
in writing and to each Holder of Securities in the manner set forth in Section
1.06.

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.02, (iii) any request to institute
proceedings referred to in Section 5.07(2) or (iv) any direction referred to in
Section 5.12. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount at maturity of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Trustee from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with


                                      -35-
<PAGE>


no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount at maturity of Outstanding Securities on the
date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the Issuer's expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Issuer in writing and to each Holder of Securities in the
manner set forth in Section 1.06.

                  With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities in the manner set forth in Section
1.06, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

                  Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

                  SECTION 1.05. Notices, Etc., to Trustee, Issuer and
Guarantors. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

         the Holders, or

                  (2) the Issuer or either Guarantor by the Trustee or by any
         Holder shall be sufficient for every purpose hereunder (unless
         otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Issuer or either Guarantor as
         applicable, addressed to it, if prior to receipt by the Trustee of
         written notice pursuant to this Section 1.05 of a change of address, at
         the address of its principal office specified in the first paragraph of
         this instrument, or, if after receipt by the Trustee of written notice
         pursuant to this Section 1.05 of a change of address, at such other
         address as may be previously furnished in writing to the Trustee by the
         Issuer or either Guarantor, as applicable.

                  SECTION 1.06. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date
(if any), and not earlier than the earliest date (if any), prescribed for the
giving of such notice. 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,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. 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 1.07. Application of Trust Indenture Act. The Trust
Indenture Act shall apply as a matter of contract to this Indenture for purposes
of interpretation, construction and defining the rights and obligations


                                      -36-
<PAGE>


hereunder. If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

                  SECTION 1.08. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 1.09. Successors and Assigns. All covenants and
agreements in this Indenture by the Issuer and the Guarantors shall bind their
respective successors and assigns, whether so expressed or not.

                  SECTION 1.10. Separability Clause. In case any provision in
this Indenture or in the Securities shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

                  SECTION 1.11. Benefits of Indenture. Nothing in this Indenture
or in the Securities, express or implied, shall give to any Person, other than
the parties hereto and their successors hereunder and the Holders of Securities,
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

                  SECTION 1.12. Governing Law. This Indenture, the Securities
and the Securities Guarantee shall be governed by and construed in accordance
with the laws of the State of New York.

                  SECTION 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, Purchase Date or Stated Maturity of any Security
shall not be a Business Day, then (notwithstanding any other provision of this
Indenture or of the Securities) payment of interest or principal (and premium,
if any) 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, Redemption Date, Purchase Date or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date, Purchase Date or Stated Maturity, as the case may be.

                  SECTION 1.15. Agent for Service; Submission to Jurisdiction;
Waiver of Immunities. By the execution and delivery of this Indenture, each of
the Issuer, the Parent Guarantor and the Subsidiary Guarantor (i) represents
that it has designated and appointed RSL Communications N. America, Inc.
("RSLNA"), as its authorized agent upon which process may be served in any suit,
action or proceeding arising out of or relating to the Securities, the
Securities Guarantee or this Indenture that may be instituted in any Federal or
state court in the State of New York, Borough of Manhattan, or brought under
Federal or state securities laws or brought by the Trustee (whether in its
individual capacity or in its capacity as Trustee hereunder), and that RSLNA has
accepted such designation, (ii) submits to the non-exclusive jurisdiction of any
such court in any such suit, action or proceeding, (iii) agrees that service of
process upon RSLNA and written notice of said service to the Issuer or the
Parent Guarantor, as applicable, (mailed or delivered to its President at its
principal office as specified in Section 1.05) shall be deemed in every respect
effective service of process upon it in any such suit or proceeding, and (iv)
agrees to take any and all action, including the execution and filing of any and
all such documents and instruments as may be necessary to continue such
designation and appointment of RSLNA in full force and effect so long as any of
the Securities shall be Outstanding.

                  To the extent that the Issuer or either Guarantor has or
hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, each of the Issuer, Parent Guarantor and the Subsidiary
Guarantor hereby irrevocably waives such immunity in respect of its obligations
under this Indenture, the Securities Guarantee and the Securities, to the extent
permitted by law.

                                   ARTICLE II

                                 Security Forms

                  SECTION 2.01. Forms Generally. The Securities and the
Trustee's certificates of authentication thereof shall be in substantially the
forms set forth in this Article, with such appropriate legends, insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture, and may have such


                                      -38-
<PAGE>


letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such Securities, as evidenced by their execution of the
Securities.

                  Upon their original issuance, Rule 155A Securities shall be
issued in the form of a Global Security in bearer form without interest coupons,
which shall be deposited on behalf of the Initial Purchasers with the Book-Entry
Depositary at its New York corporate trust office, duly executed by the Issuer
and authenticated by the Trustee as hereinafter provided. Such Global Security,
together with its Successor Securities which are Global Securities other than
the Regulation S Global Security, are collectively herein called the "Restricted
Global Security". Upon their original issuance, Regulation S Securities shall be
issued in the form of a Global Security in bearer form without interest coupons,
which shall be deposited on behalf of the Initial Purchasers with the Book-Entry
Depositary at its New York corporate trust office, duly executed by the Issuer
and authenticated by the Trustee as hereinafter provided. Such Global Security,
together with its Successor Securities which are Global Securities other than
the Restricted Global Security, are collectively herein called the "Regulation S
Global Security".

                  Upon receipt of the Restricted Global Security and the
Regulation S Global Security authenticated and delivered by the Trustee, the
Book-Entry Depositary shall issue to the Depositary a Depositary Interest in
each such Global Security by recording the Depositary Interest in the register
of the Book Entry Depositary in the name of Cede & Co., as nominee of the
Depositary. Ownership of beneficial interests shall be limited to Participants,
including Euroclear and Clearstream, and Indirect Participants. Upon the
issuance of the Depositary Interest in such Global Security to the Depositary,
the Depositary shall credit, on its internal book-entry registration and
transfer system, its Participant's accounts with respective interests owned by
such Participants.

                  Neither the Depositary nor its Participants shall have any
rights either under this Indenture or under any Global Security with respect to
such Global Security held on their behalf by the Book-Entry Depositary, and the
Book- Entry Depositary may be treated by the Issuer, the Trustee and any agent
of the Issuer or the Trustee as the absolute owner of such Global Security for
the purpose of receiving


                                      -39-
<PAGE>


payment of or on account of the principal of (premium, if any) and, subject to
the provisions of this Indenture, interest on the Global Security and for all
other purposes. Notwithstanding the foregoing, nothing herein shall prevent the
Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect
to any written certification, proxy or other authorization furnished by the
Book-Entry Depositary or impair, as between the Book-Entry Depositary and the
Depositary and its Participants, the operation of customary practices of such
Depositary governing the exercise of the rights of an owner of a beneficial
interest in any Global Security.

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

the bearer hereof] [If this Security is not a Global Security issued in bearer
form, then insert: _____________, or registered assigns], the principal sum of
______________ DOLLARS [if this Security is a Global Security, then insert:
(which principal amount may from time to time be increased or decreased to such
other principal amounts by adjustments made on the records of the Trustee
hereinafter referred to in accordance with the Indenture)] on March 1, 2010, and
to pay interest thereon from February 22, 2000 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, semi-annually
on March 1 and September 1, in each year, at the rate of 12.875% per annum,
until the principal hereof is paid or made available for payment; [If Original
Securities, then insert: provided, however, that if the Issuer has not filed a
registration statement (an "Exchange Offer Registration Statement") under the
Securities Act of 1933, as amended (the "Securities Act"), registering a
security substantially identical to this Security (except that such Security
will not contain terms with respect to the Special Interest payments described
below or transfer restrictions) pursuant to an exchange offer (the "Exchange
Offer") (or, in lieu thereof, a registration statement registering this Security
for resale (a "Resale Registration Statement")), and (i) the Exchange Offer has
not been completed by 210 days after the date of original issuance of this
Security or its predecessors (if an Exchange Offer is then required to be made
pursuant to the Exchange and Registration Rights Agreement (an "Exchange and
Registration Rights Agreement"), by and between the Issuer, the Parent
Guarantor, as defined in the Indenture, the Subsidiary Guarantor as defined in
the Indentrue, the Purchasers (as defined therein) and the Holders from time to
time of the Securities) or (ii) any Resale Registration Statement required to be

additional registration statement filed and declared effective upon the terms

such event referred to in clauses (i) and (ii), a "Registration Default"), then
interest will accrue (in addition to the stated interest on the Securities) (the
"Step-Up") at a rate of 0.5% per annum, determined daily, on the principal
amount of the Securities, from the period from and including the date of
occurrence of the Registration Default to but excluding such date (the
"Step-Down Date") as no Registration Default is in effect (commencing on which
date such interest rate will be restored to its initial rate). Interest accruing
as a result of the Step-Up is referred to herein as "Special Interest." Accrued
Special Interest, if any, shall be paid semi-annually on March 1 and September 1
in each year; and the amount of accrued Special Interest shall be determined on
the basis of the number of days actually elapsed. Any accrued and unpaid
interest (including Special Interest) on this Security upon the issuance of an
Exchange Security (as defined in the Indenture) in exchange for this Security
shall cease to be payable to the Holder hereof but such accrued and unpaid
interest (including Special Interest) shall be payable on the next Interest
Payment Date for such Exchange Security to the Holder thereof [if not a Global
Security in bearer form, insert: on the related Regular Record Date].] The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in such Indenture, be paid to [If this Security

provided for will forthwith cease to be payable to the Holder on such Interest
Payment Date and may either be paid to [If this Security is a Global Security

Date] [If this Security is not a Global Security issued in bearer form, then
insert: the Person in whose name this Security (or one or more Predecessor

any securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in said
Indenture.

Issuer (or the Guarantors) also shall pay Additional Amounts to the Holders of
Securities equal to an amount that the Issuer or Guarantors, as the case may be,

Guarantee.

paid on demand, such interest shall itself bear interest at the rate of 15.875%
per annum (to the extent that the payment of such interest shall be legally
enforceable), and shall accrue from the date of such demand for payment to the
date payment of such interest has been made or duly provided for, and such
interest on unpaid interest shall also be payable on demand.

corporate trust office of the Trustee and at the office or agency of the Issuer
maintained for that purpose in the Borough of Manhattan, The City of New York,
New York, and at any other office or agency maintained by the Issuer for such
purpose, in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Issuer payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address [If
this Security is a Global Security in bearer form, then insert: is specified by
the bearer hereof] [If this Security is a Definitive Security, then insert:

Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

executed by the Trustee referred to on the reverse hereof by manual signature,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

                  SECTION 2.03. Form of Reverse of Security. This Security is
one of a duly authorized issue of Securities of the Issuer designated as its
12 7/8% Senior Notes due 2010 (the "Securities") issued under an Indenture,
dated as of February 22, 2000 (herein called the "Indenture"), between the
Issuer, RSL Communications, Ltd., as a Parent Guarantor (the "Parent Guarantor",
which term includes any successor Person under the Indenture) RSL COM U.S.A.,
Inc., as a guarantor (the "Subsidiary Guarantor", which term includes any
successor Person under the Indenture, and together with the Parent Guarantor,
the "Guarantors") and The Chase Manhattan Bank, as trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture).
Reference is hereby made to the Indenture and all indentures supplemental
thereto for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Issuer, the Guarantors, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

                  The Securities are subject to redemption upon not less than 30
nor more than 60 days' notice by mail to each Holder of Securities to be
redeemed at such Holder's address appearing in the Security Register, in amounts
of $1,000 or an integral multiple of $1,000, at any time on or after March 1,
2005 and prior to maturity, as a whole or in part, at the election of the
Issuer, at the following Redemption Prices (expressed as percentages of the

interest installments whose Stated Maturity is on or prior to such Redemption

Predecessor Securities [If this Security is not a Global Security issued in
bearer form, insert:, of record at the close of business on the relevant Record
Dates referred to on the face hereof,] all as provided in the Indenture.

                  In addition, at any time prior to March 1, 2003, in the event
that the Parent Guarantor receives net cash proceeds from the public or private
sale of its Common Stock (other than Disqualified Stock), the Issuer (to the
extent it receives such proceeds and has not used such proceeds, directly or
indirectly, to redeem or repurchase other securities pursuant to optional
redemption provisions) may, at its option, apply an amount equal to any such net
cash proceeds or any portion thereof to redeem, from time to time, Securities in
a principal amount at maturity of up to an aggregate amount equal to 33 1/3% of
the original aggregate principal amount at maturity of the Securities; provided,
however, that Securities in an amount equal to at least 66 2/3% of the aggregate
original principal amount at maturity of the Securities remain Outstanding after
each redemption. Each redemption must occur on a Redemption Date within 180 days
of the related sale and upon not less than 30 nor more than 60 days' notice by
mail to each Holder of Securities to be redeemed at such Holder's address
appearing in the Security Register, in amounts of $1,000 or an integral multiple
of $1,000 at a Redemption Price of 112.875% of the principal amount of the
Securities plus accrued interest to but excluding the Redemption Date.

                  Furthermore, in the event that (i) the Guarantors or the
Issuer has become or would become obligated to pay any Additional Amounts as a
result of (x) changes affecting withholding tax laws or (y) a Listing Failure,
provided that the Issuer has used reasonable best efforts to list and maintain a
listing of the Securities on a "recognized stock exchange" (within the meaning
of Section 851 of the U.K. Income and Corporation Taxes Act 1988) (as provided
for in Section 10.09), and (ii) the Guarantors and the Issuer are unable to
avoid the requirement to pay such Additional Amounts by taking reasonable
measures available to them (including, without limitation, the Guarantors making
payments directly to holders under the Securities Guarantee, unless such payment
is likely to result in adverse consequences to the Issuer or the Guarantors),
then the Issuer may redeem all, but not less than all, of the Securities at any
time at 100% of the principal amount


                                      -57-

thereof on the Redemption Date, together with accrued interest thereon, if any,
to but excluding the Redemption Date. Prior to the publication of the notice of
redemption in accordance with the foregoing, the Issuer shall deliver to the
Trustee an officer's certificate stating that the Issuer is entitled to effect
such redemption based on a written opinion of independent tax counsel or
accounting firm reasonably satisfactory to the Trustee.

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Indenture provides that, subject to certain conditions, if
(i) a Change of Control occurs or (ii) certain Net Available Proceeds are
available to the Issuer as a result of any Asset Disposition, the Issuer shall
be required to make an Offer to Purchase for all or a specified portion of the
Securities.

                  [If not a Global Security: In the event of redemption or
purchase pursuant to an Offer to Purchase of this Security in part only, a new
Security or Securities of like tenor for the unredeemed or unpurchased portion
hereof will be issued in the name of the Holder hereof upon the cancelation
hereof.]

                  [If a Global Security insert: In the event of a deposit or
withdrawal of a beneficial interest in this Security (including upon an
exchange, transfer, redemption or repurchase of this Security in part only)
effected in accordance with the Applicable Procedures, the Security Registrar,
upon receipt of notice of such event from the Depositary's custodian for this
Security shall make an adjustment on its records to reflect an increase or
decrease of the Outstanding principal amount at maturity of this Security
resulting from such deposit or withdrawal, as the case may be, and shall
instruct the Book-Entry Depositary to make a similar notation in its book-entry
system to the corresponding Depositary Interest.]

                  If an Event of Default shall occur and be continuing, the
principal of all the Securities may be declared due and payable in the manner
and with the effect provided in the Indenture.

                  The Indenture contains provisions for defeasance at any time
of (i) the entire indebtedness of this Security, or (ii) certain restrictive
covenants and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

                  Unless the context otherwise requires, the Original Securities
and the Exchange Securities shall constitute one series for all purposes under
the Indenture, including without limitation, amendments, waivers, redemptions
and Offers to Purchase.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer, the Guarantors and the rights of the Holders of the
Securities under the Indenture at any time by the Issuer, the Guarantors and the
Trustee with the consent of the Holders of a majority in aggregate principal
amount at maturity of the Securities at the time Outstanding. The Indenture also
contains provisions permitting the Holders of specified percentages in aggregate
principal amount at maturity of the Securities at the time Outstanding, on
behalf of the Holders of all the Securities, to waive compliance by the Issuer
or the Guarantors with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

                  [If this Security is not a Global Security issued in bearer
form, then insert: As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Issuer in the Borough of Manhattan, the
City of New York, New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Issuer and the Security
Registrar duly executed by the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securities, of authorized denominations
and like tenor and for the same aggregate principal amount at maturity, will be
issued to the designated transferee or transferees.]

                  The Global Securities are issuable only in bearer form without
coupons in denominations of $1,000 and any integral multiple thereof. Definitive
Securities shall be issuable in registered form without interest coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like tenor and aggregate principal amount at maturity of
Securities of a different authorized denomination, as requested by the Holder
surrendering the same.

                  [If this Security is a Global Security issued in bearer form,
then insert: The bearer of this Security shall be treated as the owner of this
Security for all purposes.]

                  No service charge shall be made for any such registration of
transfer or exchange, but the Issuer may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  [If this Security is not a Global Security issued in bearer
form, insert: Prior to due presentment of this Security for registration of
transfer, the Issuer, the Guarantors, the Trustee and any agent of the Issuer,
the Guarantors, or the Trustee may treat the Person in whose name this Security
is registered as the owner hereof for all purposes, whether or not this Security
be overdue, and neither the Issuer, the Parent Guarantor, the Subsidiary
Guarantor, the Trustee nor any such agent shall be affected by notice to the
contrary.]

                  Interest on this Security shall be computed on the basis of a
360-day year of twelve 30-day months [If Original Securities, then insert:   ;
provided, however, that Special Interest shall be computed on the basis of a
365- or 366-day year, as the case may be, and the number of days actually
elapsed].

                  Generally, when a successor Person assumes all of the
obligations of its predecessor under the Notes and the Indenture, the
predecessor Person will be released from these obligations. In addition, the
Subsidiary Guarantor may be released from the Securities Guarantee under certain
circumstances provided in the Indenture.

                  All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

                                 The Securities

                  SECTION 3.01. Title and Terms. The aggregate principal amount
of Securities which may be authenticated and delivered under this Indenture is
unlimited; provided that unless the Issuer authorizes the execution and delivery

amount of Securities shall be limited to $100,000,000 except for Securities
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, other Securities pursuant to Section 3.05, 3.05, 3.06, 9.06
or 11.08 or in connection with an Offer to Purchase pursuant to Section 10.13 or
10.17 (all Securities referred to in this exception being deemed "Substitute
Securities"). The Issuer may issue Exchange Securities from time to time
pursuant to an Exchange Offer or otherwise, in each case pursuant to a Board
Resolution, subject to Section 3.03, included in an Officers' Certificate
delivered to the Trustee, in authorized denominations in exchange for a like
principal amount at maturity of Original Securities. Upon any such exchange the
Original Securities shall be canceled in accordance with Section 3.09 and shall
no longer be deemed Outstanding for any purpose. In no event shall the aggregate
principal amount at maturity of Original Securities and Exchange Securities
Outstanding exceed $100,000,000.

                  The Securities shall be known and designated as the "12 7/8%

22, 2000 or from the most recent Interest Payment Date thereafter to which
interest has been paid or duly provided for, as the case may be, payable
semi-annually on March 1 and September 1, commencing September 1, 2000, until
the principal thereof is paid or made available for payment; provided, however,
with respect to Original Securities, if there has been a Registration Default, a
Step-Up will occur and the Original Securities will from then bear Special
Interest to but excluding the Step-Down Date. Accrued Special Interest, if any,
shall be paid in cash in arrears semi-annually on March 1 and September 1 in
each year, and the amount of accrued Special Interest shall be determined on the
basis of the number of days actually elapsed.

                  With respect to Global Securities, the Issuer will pay
interest, if any, on such Securities to the bearers of such Securities. Holders
of such Global Securities must surrender such Securities to the Trustee to
collect principal payments. The principal of and premium, if any, and interest
on the Securities shall be payable at the


                                      -52-

corporate trust office of the Trustee in the Borough of Manhattan, the City of
New York, New York, maintained for such purpose and at any other office or
agency maintained by the Issuer for such purpose; provided, however, that at the
option of the Issuer payment of interest may be made by check mailed to the

Security Register.

                  The Securities shall be redeemable as provided in Article
Eleven.

                  The Securities shall not have the benefit of any sinking fund
obligations.

                  The Securities shall be subject to defeasance at the option of
the Issuer as provided in Article Twelve.

                  The Securities are guaranteed by the Guarantors as set forth
in Article IV of this Indenture.

                  A copy of an appropriate record of such action shall be
certified by the Secretary or any Assistant Secretary of the Issuer and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate or the trust indenture supplemental hereto setting forth the terms
of such Securities.

                  Unless the context otherwise requires, the Original Securities
and the Exchange Securities shall constitute one series for all purposes under
the Indenture, including without limitation, amendments, waivers, redemptions
and Offers to Purchase.

                  SECTION 3.02. Denominations. The Global Securities shall be
issuable in bearer form without coupons and only in denominations of $1,000 and
any integral multiple of $1,000 in excess thereof. Definitive Registered
Securities shall be issuable in registered form without interest coupons in
denominations of $1,000 and any integral multiple thereof.

                  SECTION 3.03. Execution, Authentication, Delivery and Dating.

Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Issuer shall bind
the Issuer, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Issuer may deliver Securities executed by the
Issuer to the Trustee for authentication, together with a Issuer Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Issuer Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise.

                  At any time and from time to time after the execution and
delivery of this Indenture and after the effectiveness of a Registration
Statement under the Securities Act with respect thereto, the Issuer may deliver
Exchange Securities executed by the Issuer to the Trustee for authentication,
together with an Issuer Order for the authentication and delivery of such
Exchange Securities and a like principal amount at maturity of Original
Securities for cancelation in accordance with Section 3.09 of this Indenture,
and the Trustee in accordance with the Issuer Order shall authenticate and
deliver such Securities. In authenticating such Exchange Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to
Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel
stating,

                  (a) that such Exchange Securities have been duly and validly
         issued in accordance with the terms of the Indenture, and are entitled
         to all the rights and benefits set forth herein; and

                  (b) that the issuance of the Exchange Securities in exchange
         for the Original Securities has been effected in compliance with the
         Securities Act of 1933, as amended.

                  Each Security shall be dated the date of its authentication.

<PAGE>


                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

                  SECTION 3.05. Temporary Securities. Pending the preparation of
definitive Securities, the Issuer may execute, and upon Issuer Order the Trustee
shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

                  If temporary Securities are issued, the Issuer will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Issuer designated pursuant to Section
10.02, without charge to the Holder. Upon surrender for cancelation of any one
or more temporary Securities, the Issuer shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like tenor and principal amount
at maturity of definitive Securities of authorized denominations. Until so
exchanged, the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities.

                  SECTION 3.05. Registration, Registration of Transfer and
Exchange. (a) The Issuer shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.02 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Issuer shall provide for the
registration of Definitive Securities and of transfers of such Securities. The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
such Securities and transfers of such Securities as herein provided. Such
Security Register shall distinguish between Original Securities and Exchange
Securities.

<PAGE>


                  Subject to the other provisions of this Indenture regarding
restrictions on transfer, upon surrender for registration of transfer of any
Definitive Security at an office or agency of the Issuer designated pursuant to
Section 10.02 for such purpose in accordance with the terms hereof, the Issuer
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like tenor and aggregate principal amount at
maturity and bearing such restrictive legends as may be required by this
Indenture.

                  At the option of the Holder, and subject to the other
provisions of this Section 3.05, Securities may be exchanged for other
Securities of any authorized denominations and of a like tenor and aggregate
principal amount at maturity, upon surrender of such Securities to be exchanged
at such office or agency. Whenever any Securities are so surrendered for
exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Issuer, evidencing
the same debt, and (subject to the provisions in the Original Securities
regarding the payment of Special Interest) entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Issuer or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Security Registrar 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 Securities, but the Issuer may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 3.05, 3.05(d), 9.06 or
11.08 or in accordance with any Offer to Purchase pursuant to Section 10.13 or
10.17 not involving any transfer.

                  The Issuer shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 11.05 and ending at the close
of business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

                  (b) Certain Transfers and Exchanges. Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 3.05(b) shall be made only in accordance with this Section
3.05(b) or, if necessary, in accordance with such other procedures as the Issuer
shall develop which shall comply with applicable securities laws.

                         (i) Restricted Global Security to Regulation S Global
         Security. If the owner of a beneficial interest in the Restricted
         Global Security wishes at any time to transfer such interest to a
         Person who wishes to acquire the same in the form of a beneficial
         interest in the Regulation S Global Security, such transfer may be
         effected only in accordance with the provisions of this Clause (b)(i)
         and Clause (b)(v) below and subject to the Applicable Procedures. Upon
         receipt by the Trustee, as Security Registrar, of (A) an order given by
         the Depositary or its authorized representative directing that a
         beneficial interest in the Regulation S Global Security in a specified
         Agent Member's principal amount at maturity be credited to a specified
         Agent Member's account and that a beneficial interest in the Restricted
         Global Security in an equal principal amount at maturity be debited
         from another specified Agent Member's account and (B) a Regulation S
         Certificate, satisfactory to the Trustee and duly executed by the owner
         of such beneficial interest in the Restricted Global Security or his
         attorney duly authorized in writing, then the Trustee, as Security
         Registrar but subject to Clause (b)(v) below, shall reduce or cause to
         be reduced the principal amount at maturity of the Restricted Global
         Security and increase the principal amount at maturity of the
         Regulation S Global Security by such specified principal amount at
         maturity as provided in Section 3.05(e).

                        (ii) Regulation S Global Security to Restricted Global
         Security. If the owner of a beneficial interest


                                      -57-
<PAGE>


         in the Regulation S Global Security wishes at any time to transfer such
         interest to a Person who wishes to acquire the same in the form of a
         beneficial interest in the Restricted Global Security, such transfer
         may be effected only in accordance with this Clause (b)(ii) and subject
         to the Applicable Procedures. Upon receipt by the Trustee, as Security
         Registrar, of (A) an order given by the Depositary or its authorized
         representative directing that a beneficial interest in the Restricted
         Global Security in a specified principal amount at maturity be credited
         to a specified Agent Member's account and that a beneficial interest in
         the Regulation S Global Security in an equal principal amount at
         maturity be debited from another specified Agent Member's account and
         (B) if such transfer is to occur during the Restricted Period, a
         Restricted Securities Certificate, satisfactory to the Trustee and duly
         executed by the owner of such beneficial interest in the Regulation S
         Global Security or his attorney duly authorized in writing, then the
         Trustee, as Security Registrar, shall reduce or cause to be reduced the
         principal amount at maturity of the Regulation S Global Security and
         increase the principal amount at maturity of the Restricted Global
         Security by such specified principal amount at maturity as provided in
         Section 3.05(e).

                       (iii) Definitive Security to Definitive Security. A
         Security that is a Definitive Security may be transferred, in whole or
         in part, to a Person who takes delivery in the form of another Security
         that is a Definitive Security as provided in Section 3.05(a), provided
         that, if the Security to be transferred in whole or in part is a
         Restricted Security, or is a Regulation S Security and the transfer is
         to occur during the Restricted Period, then the Trustee shall have
         received (A) a Restricted Securities Certificate, satisfactory to the
         Trustee and duly executed by the transferor Holder or his attorney duly
         authorized in writing, in which case the transferee Holder shall take
         delivery in the form of a Restricted Security, or (B) a Regulation S
         Certificate, satisfactory to the Trustee and duly executed by the
         transferor Holder or his attorney duly authorized in writing, in which
         case the transferee Holder shall take delivery in the form of a
         Regulation S Security (subject in every case to Section 3.05(c)).

                        (iv) Exchanges between Global Security and Definitive
         Security. A beneficial interest in a Global


                                      -58-
<PAGE>


         Security may be exchanged for a Security that is a Definitive Security
         as provided in Section 3.05(d), provided that, if such interest is a
         beneficial interest in the Restricted Global Security, or if such
         interest is a beneficial interest in the Regulation S Global Security
         and such exchange is to occur during the Restricted Period, then such
         interest shall be exchanged for a Restricted Security or a Regulation S
         Security, as the case may be (subject in each case to Section 3.05(c)).

                  (v) Regulation S Global Security to be Held Through Euroclear
         or Clearstream during Restricted Period. The Issuer shall use its best
         efforts to cause the Depositary to ensure that, until the expiration of
         the Restricted Period, beneficial interests in the Regulation S Global
         Security may be held only in or through accounts maintained at the
         Depositary by Euroclear or Clearstream (or by Agent Members acting for
         the account thereof), and no person shall be entitled to effect any
         transfer or exchange that would result in any such interest being held
         otherwise than in or through such an account; provided that this Clause
         (b)(v) shall not prohibit any transfer or exchange of such an interest
         in accordance with Clause (b) above.

                  (c) Securities Act Legends. Rule 155A Securities and their
Successor Securities shall bear a Restricted Securities Legend, and the
Regulation S Securities and their Successor Securities shall bear a Regulation S
Legend, subject to the following:

                         (i) subject to the following Clauses of this Section
         3.05(c), a Security or any portion thereof which is exchanged, upon
         transfer or otherwise, for a Global Security or any portion thereof
         shall bear the Securities Act Legend borne by such Global Security
         while represented thereby;

                        (ii) subject to the following Clauses of this Section
         3.05(c), a new Security which is a Definitive Security and is issued in
         exchange for a Global Security or any portion thereof, upon transfer or
         otherwise, shall bear the Securities Act Legend borne by such other
         Security, provided that, if such new Security is required pursuant to
         Section 3.05(b)(iii) or (iv) to be issued in the form of a Restricted
         Security, it shall bear a Restricted Securities Legend and, if such new
         Security is so required to be issued


                                      -59-
<PAGE>


         in the form of a Regulation S Security, it shall bear a
         Regulation S Legend;

                       (iii) Registered Securities shall not bear a
         Securities Act Legend;

                        (iv) at any time after the Securities may be freely
         transferred without registration under the Securities Act or without
         being subject to transfer restrictions pursuant to the Securities Act,
         a new Security which does not bear a Securities Act Legend may be
         issued in exchange for or in lieu of a Security (other than a Global
         Security) or any portion thereof which bears such a legend if the
         Trustee has received an Unrestricted Securities Certificate,
         satisfactory to the Trustee and duly executed by the Holder of such
         legended Security or his attorney duly authorized in writing, and after
         such date and receipt of such certificate, the Trustee shall
         authenticate and deliver such a new Security in exchange for or in lieu
         of such other Security as provided in this Article III;

                         (v) a new Security which does not bear a Securities Act
         Legend may be issued in exchange for or in lieu of a Security (other
         than a Global Security) or any portion thereof which bears such a
         legend if, in the Issuer's judgment, placing such a legend upon such
         new Security is not necessary to ensure compliance with the
         registration requirements of the Securities Act, and the Trustee, at
         the direction of the Issuer, shall authenticate and deliver such a new
         Security as provided in this Article III; and

                        (vi) notwithstanding the foregoing provisions of this
         Section 3.05(c), a Successor Security of a Security that does not bear
         a particular form of Securities Act Legend shall not bear such form of
         legend unless the Issuer has reasonable cause to believe that such
         Successor Security is a "restricted security" within the meaning of
         Rule 155, in which case the Trustee, at the direction of the Issuer,
         shall authenticate and deliver a new Security bearing a Restricted
         Securities Legend in exchange for such Successor Security as provided
         in this Article III.

                  (d) Exchanges of Global Security for Definitive Security.
Transfers of Global Securities shall be by delivery. The Book-Entry Depositary
and the Issuer have agreed that the Global Securities shall only be delivered in
the circumstances described in the Deposit Agreement.


                                      -60-
<PAGE>


Notwithstanding any other provision in this Indenture, no Global Security may be
exchanged in whole or in part for Definitive Securities unless (i) the
Depositary notifies the Issuer or the Book-Entry Depositary in writing that it
(or its nominee) is unwilling or unable to continue to act as depositary, or
ceases to be, a clearing agency registered under the Exchange Act, and, in
either case, a successor depositary registered as a clearing agency under the
Exchange Act is not appointed by the Issuer within 90 days, (ii) at any time if
the Issuer determines that the Global Securities (in whole but not in part)
should be exchanged for Definitive Securities; provided, that (x) such exchange
is required by (A) any applicable law or (B) any event beyond the Issuer's
control or (y) payments of interest on any Global Security, Depositary Interest
or beneficial interest are, or would become, subject to any deduction or
withholding for taxes, (iii) at any time after the consummation of the Exchange
Offer, if the owner of a beneficial interest requests such exchange in writing
delivered to the Depositary and through the Depositary to the Book-Entry
Depositary and the Trustee, or (iv) if the Book-Entry Depositary is at any time
unwilling or unable to continue as Book-Entry Depositary and a successor
Book-Entry Depositary is not appointed by the Issuer within 90 days. Upon the
occurrence of any of the preceding events, Definitive Securities shall be issued
in such names as the Book-Entry Depositary shall instruct the Trustee based on
the instructions of the Depositary.

                  (e) If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Book-Entry Depositary or its nominee to the Trustee, as Security Registrar, for
exchange or cancelation as provided in this Article III. If any Global Security
is to be exchanged for other Securities or canceled in part, or if another
Security is to be exchanged in whole or in part for a beneficial interest in any
Global Security, then either (i) such Global Security shall be so surrendered
for exchange or cancelation as provided in this Article III or (ii) the
principal amount at maturity thereof shall be reduced or increased by an amount
equal to the portion thereof to be so exchanged or canceled, or equal to the
principal amount at maturity of such other Security to be so exchanged for a
beneficial interest therein, as the case may be, by means of an appropriate
adjustment made by the Book-Entry Depositary as directed by the Trustee in such
Book-Entry Depositary's book-entry system to the corresponding Depositary
Interest, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized


                                      -61-
<PAGE>


representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Security, the Trustee shall, subject to
Section 3.05(b) and as otherwise provided in this Article III, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered (if applicable) in such
names as may be directed by, the Book-Entry Depositary or its authorized
representative. Upon the request of the Trustee in connection with the
occurrence of any of the events specified in the preceding paragraph, the Issuer
shall promptly make available to the Trustee a reasonable supply of Securities
that are not in the form of Global Securities. The Trustee shall be entitled to
rely upon any order, direction or request of the Book-Entry Depositary or the
Depositary or any of their authorized representatives which is given or made
pursuant to this Article III if such order, direction or request is given or
made in accordance with the Deposit Agreement with respect to the Book-Entry
Depositary and the Applicable Procedures with respect to the Depositary.

                  SECTION 3.06. Mutilated, Destroyed, Lost and Stolen
Securities. If any mutilated Security is surrendered to the Trustee, the Issuer
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount at maturity and
bearing a number not contemporaneously outstanding.

                  If there shall be delivered to the Issuer and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of written
notice to the Issuer or the Trustee that such Security has been acquired by a
bona fide purchaser, the Issuer shall execute and the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of like tenor and principal amount at maturity and bearing a number not
contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Issuer in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section, the
Issuer may require the payment of a sum sufficient to cover any tax or other
governmental charge


                                      -62-
<PAGE>


that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Trustee) connected therewith.

                  Every new Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Issuer, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                  SECTION 3.07. Payment of Interest; Interest Rights Preserved.
Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the bearer thereof
on the Interest Payment Date in the case of a Global Security in bearer form
and, in the case of a Definitive Security, to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

                  Any interest (including Special Interest) on any Security
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall (a) bear
interest at the rate per annum stated in the form of Security included herein
(to the extent that the payment of such interest shall be legally enforceable),
and (b) forthwith cease to be payable to the bearer thereof on such Interest
Payment Date with respect to a Global Security in bearer form and, with respect
to a Definitive Security, to the Holder on the relevant Regular Record Date by
virtue of having been such Holder, and, in each case, such Defaulted Interest
may be paid by the Issuer, at its election in each case, as provided in Clause
(a) or (b) below:

                  (a) The Issuer may elect to make payment of any Defaulted
         Interest to the bearer of such Security on any Special Payment Date (as
         defined below) with respect to any Global Security in bearer form and,
         with respect to a Definitive Security, to the Persons in whose names
         the Securities (or their respective Predecessor Securities) are
         registered at the close of


                                      -63-
<PAGE>


         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Issuer
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on each Security and the date of the proposed
         payment, and at the same time the Issuer 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 which shall be not more than
         15 days and not 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 Issuer of such Special Record Date and, in the name and at the
         expense of the Issuer, shall cause notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor to be
         mailed, first-class postage prepaid, to each Holder, 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 so mailed, such Defaulted Interest shall be paid, with respect to
         any Definitive Security, to the Persons in whose names the Securities
         (or their respective Predecessor Securities) are registered at the
         close of business on such Special Record Date and shall no longer be
         payable pursuant to the following Clause (b). As used in this Clause
         (a), "Special Payment Date" means the date on which Defaulted Interest
         is paid to the Holder.

                  (b) The Issuer may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Securities may be listed, and upon
         such notice as may be required by such exchange, if, after notice given
         by the Issuer 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
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest


                                      -65-
<PAGE>


accrued and unpaid, and to accrue, which were carried by such other Security.

                  SECTION 3.08. Persons Deemed Owners. Prior to due presentment
of a Security for registration of transfer, the Issuer, the Parent Guarantor,
the Subsidiary Guarantor, the Trustee and any agent of the Issuer, the Parent
Guarantor, the Subsidiary Guarantor or the Trustee may treat the Person in whose
name a Definitive Security is registered as the owner of such Security and may
treat the bearer of a Global Security as the owner of such Security, in each
case, for the purpose of receiving payment of principal of and premium, if any,
and (subject to Section 3.07) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Issuer, the Parent Guarantor, the Subsidiary Guarantor, the Trustee nor any
agent of the Issuer, the Parent Guarantor, the Subsidiary Guarantor or the
Trustee shall be affected by notice to the contrary.

                  SECTION 3.09. Cancelation. All Securities surrendered for
payment, redemption, registration of transfer, exchange or pursuant to any Offer
to Purchase pursuant to Section 10.13 or 10.17 shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly
canceled by it. The Issuer may at any time deliver to the Trustee for
cancelation any Securities previously authenticated and delivered hereunder
which the Issuer may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in accordance with its
standard procedures or as directed by an Issuer Order; provided, however, that
the Trustee shall not be required to destroy such Securities.

                  SECTION 3.10. Computation of Interest. Interest on the
Securities shall be computed on the basis of a 360-day year of twelve 30-day
months, provided, however, that Special Interest on Original Securities shall be
computed on the basis of a 365- or 366-day year, as the case may be, and the
number of days actually elapsed.

                  SECTION 3.11. CUSIP and ISIN Numbers. The Issuer in issuing
Securities may use "CUSIP and "ISIN" numbers (if then generally in use) in
addition to serial numbers; if so, the Trustee shall use such "CUSIP" and "ISIN"
numbers in


                                      -65-
<PAGE>


addition to serial numbers in notices of redemption and repurchase as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such "CUSIP" and "ISIN" numbers
either as printed on the Securities or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Securities, and any such redemption
or repurchase shall not be affected by any defect in or omission of such "CUSIP"
and "ISIN" numbers.

                  SECTION 3.12. Additional Securities. Subject to Article X of
this Indenture, the Issuer may authorize the issuance of Additional Securities.
All Securities originally issued on the date of this Indenture and any
Additional Securities originally issued after the date of this Indenture shall
be treated as a single class of Securities for all purposes under this
Indenture.

                  Additional Securities shall be issued, authenticated and
delivered in accordance with the provisions of Section 3.03 and shall be
entitled to the benefits of the Guarantees of the Guarantors to the same extent
as all other Securities. The Issuer shall specify in the Issuer Order pursuant
to Section 3.03 the aggregate principal amount of Additional Securities and
shall certify that the issuance complies with the requirements of the Indenture,
including Article X. The Issuer shall be entitled to issue Additional Securities
initially as Original Securities or as Exchange Securities. If Additional
Securities are issued as Original Securities, they may be exchanged for Exchange
Securities in accordance with this Indenture and the applicable Exchange and
Registration Rights Agreement.

                                   ARTICLE IV

                             Guarantee Of Securities

                  SECTION 5.01. Guarantee. Subject to the provisions of this
Article Four, the Guarantors hereby fully, unconditionally and irrevocably
guarantee to each Holder and to the Trustee on behalf of the Holders: (i) the
due and punctual payment of the principal of, premium, if any, on and interest
(including Special Interest) on each Security, when and as the same shall become
due and payable, whether at maturity, by acceleration or otherwise, the due and
punctual payment of interest on the overdue principal of and interest, if any,
on the Securities, to the extent


                                      -66-
<PAGE>


lawful, and the due and punctual performance of all other obligations of the
Issuer to the Holders or the Trustee, all in accordance with the terms of such
Security and this Indenture and (ii) in the case of any extension of time of
payment or renewal of any Securities or any of such other obligations, that the
same will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, at Stated Maturity, by acceleration or
otherwise. The Guarantors hereby waive diligence, presentment, demand of
payment, filing of claims with a court in the event of merger or bankruptcy of
the Issuer, any right to require a proceeding first against the Issuer, the
benefit of discussion, protest or notice with respect to any such Security or
the debt evidenced thereby and all demands whatsoever, and covenants that this
Securities Guarantee will not be discharged as to any such Security except by
payment in full of the principal thereof and interest thereon and as provided in
Section 12.01 and Section 12.02 (subject to Section 12.06). The maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five for
the purposes of this Article Four. In the event of any declaration of
acceleration of such obligations as provided in Article Five, such obligations
(whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of this Article Four. In addition, without limiting
the foregoing provisions, upon the effectiveness of an acceleration under
Article Five, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article Four.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or either Guarantor, or any
custodian, receiver, liquidator, trustee, sequestrator or other similar official
acting in relation to the Issuer or either Guarantor, any amount paid to the
Trustee or such Holder in respect of a Security, this Securities Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect.
The Guarantors further agree, to the fullest extent that they may lawfully do
so, that, as between them, on the one hand, and the Holders and the Trustee, on
the other hand, the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Five hereof for the purposes of this
Securities Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.


                                      -67-
<PAGE>


                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Guarantors hereby irrevocably waive any claim or other rights which
they may now or hereafter acquire against the Issuer that arise from the
existence, payment, performance or enforcement of their obligations under this
Securities Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to either
Guarantor in violation of the preceding sentence and the principal of, premium,
if any, and accrued interest on the Securities shall not have been paid in full,
such amount shall be deemed to have been paid to such Guarantor for the benefit
of, and held in trust for the benefit of, the Holders, and shall forthwith be
paid to the Trustee for the benefit of the Holders to be credited and applied
upon the principal of, premium, if any, and accrued interest on the Securities.
The Guarantors acknowledge that they will receive direct and indirect benefits
from the issuance of the Securities pursuant to this Indenture and that the
waivers set forth in this Section 5.01 are knowingly made in contemplation of
such benefits.

                  The Guarantee set forth in this Section 5.01 shall not be
valid or become obligatory for any purpose with respect to a Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 5.02. Obligations Unconditional. Subject to Section
5.05, nothing contained in this Article Four or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Guarantors and
the holders of the Securities, the obligation of the Guarantors, which is
absolute and unconditional, upon failure by the Issuer, to pay to the holders of
the Securities the principal of, premium, if any, and interest on the Securities
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Securities and creditors of


                                      -68-
<PAGE>


either Guarantor, nor shall anything herein or therein prevent the holder of any
Securities or the Trustee on their behalf from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article Four will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 or to
pursue any rights or remedies hereunder.

                  SECTION 5.03. Notice to Trustee. The Guarantors shall give
prompt written notice to the Trustee of any fact known to either Guarantor which
would prohibit the making of any payment to or by the Trustee in respect of the
Securities Guarantee pursuant to the provisions of this Article Four.

                  SECTION 5.05. Release of Subsidiary Guarantor. The Subsidiary
Guarantor shall be automatically and unconditionally released and discharged
from its obligations under this Securities Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Parent Guarantor, of all of
the Parent Guarantor's and each Restricted Subsidiary's Capital Stock in, or all
or substantially all the assets of, the Subsidiary Guarantor (which sale,
exchange or transfer is not prohibited by this Indenture) or (ii) at any time,
so long as in the case of this clause (ii) Standard & Poor's Corporation is
notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications. Upon the release and
discharge of the Subsidiary Guarantor from its obligations under the Securities
Guarantee pursuant to this Section 5.05, the Subsidiary Guarantor shall also be
released and discharged from any other obligations it has under this Indenture
in its capacity as Subsidiary Guarantor, provided that no such release and
discharge shall affect any obligation of the Subsidiary Guarantor in its
capacity as a Restricted Subsidiary of the Guarantor.

                                      -71-

         constituting such Guarantor or the Issuer shall cease to be such
         Guarantor or the Issuer following a transaction governed by the
         provisions of Article VIII.

                  SECTION 5.02. Acceleration of Maturity; Rescission and
Annulment. If an Event of Default (other than an Event of Default specified in
Section 5.01(h) or (i)) occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in principal amount at maturity
of the Outstanding Securities may declare the principal amount at maturity of
all the Securities to be due and payable immediately, by a notice in writing to
the Issuer (and to the Trustee if given by Holders), and upon any such
declaration such principal amount and any accrued interest shall become
immediately due and payable. If an Event of Default specified in Section 5.01(h)
or (i) occurs, the principal amount of and any accrued interest on the
Securities then Outstanding shall ipso facto become immediately due and payable
without any declaration or other Act on the part of the Trustee or any Holder.

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due based on
acceleration has been obtained by the Trustee as hereinafter in this Article


                                      -72-
<PAGE>


provided, the Holders of a majority in principal amount at maturity of the
Outstanding Securities, by written notice to the Issuer and the Trustee, may
rescind and annul such declaration and its consequences if:

                  (1) the Issuer has paid or deposited with the
         Trustee a sum sufficient to pay

                           (A) all overdue interest on all Securities,

                           (B) the principal amount of (and premium, if any, on)
                  any Securities which have become due otherwise than by such
                  declaration of acceleration (including any Securities required
                  to have been purchased on the Purchase Date pursuant to an
                  Offer to Purchase made by the Issuer) and interest thereon at
                  the rate borne by the Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate borne by
                  the Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

         and

                  (2) all Events of Default, other than the non- payment of the
         principal of Securities which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 5.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                        SECTION 5.03. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Issuer covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof or, with
         respect to any Security required to have been purchased pursuant to an
         Offer to


                                      -73-
<PAGE>


         Purchase made by the Issuer, at the Purchase Date
         thereof,

the Issuer will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
provided by the Securities, and, in addition thereto, 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.

                  If the Issuer fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Issuer or any other obligor upon the Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Issuer or any other obligor upon the Securities,
wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such appropriate judicial proceedings as the Trustee shall
deem most effective to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

                  SECTION 5.05. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Issuer (or any other obligor upon the
Securities), its property or its creditors, the Trustee shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have claims of the
Holders and the Trustee allowed in any such proceeding. In particular, the
Trustee shall be authorized to collect and receive any moneys, securities or
other property payable or deliverable upon the exchange of the Securities 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


                                      -75-
<PAGE>


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 it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.07.

                  No provision of this Indenture shall be deemed to authorize
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 Securities 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;
provided, however, that the Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a
creditors or other similar committee.

                  SECTION 5.05. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

                  SECTION 5.06. Application of Money Collected. Any money
collected by the Trustee pursuant to this Article shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal (or premium, if any) or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  FIRST:  To the payment of all amounts due the
         Trustee under Section 6.07; and

                  SECOND:  To the payment of the amounts then due
         and unpaid for principal of (and premium, if any) and
         interest on the Securities in respect of which or for
         the benefit of which such money has been collected,
         ratably, without preference or priority of any kind,


                                      -75-
<PAGE>


         according to the amounts due and payable on such Securities for
         principal (and premium, if any) and interest, respectively.

                  SECTION 5.07. Limitation on Suits. No Holder of any Security
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless

                  (1) such Holder has previously given written
         notice to the Trustee of a continuing Event of Default;

                  (2) the Holders of not less than 25% in aggregate principal
         amount at maturity of the Outstanding Securities shall have made
         written request to the Trustee to institute proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered and, if requested,
         provided to the Trustee reasonable indemnity against the costs,
         expenses and liabilities to be incurred in compliance with such
         request;

                  (5) the Trustee for 60 days after its receipt of such notice,
         request and offer and, if requested, provision of indemnity has failed
         to institute any such proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount at maturity of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

                  SECTION 5.08. Unconditional Right of Holders To Receive
Principal, Premium and Interest. Notwithstanding any other provision in this
Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of (and premium, if any)
and (subject to Section 3.07) interest on such Security on the respective Stated
Maturities expressed


                                      -76-
<PAGE>


in such Security (or, in the case of redemption, on the Redemption Date or, in
the case of an Offer to Purchase made by the Issuer and required to be accepted
as to such Security, on the Purchase Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

                  SECTION 5.09. 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 Issuer, the Trustee and the Holders shall be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

                  SECTION 5.10. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.06, 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 5.11. Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder of any Security 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 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.

                  SECTION 5.12. Control by Holders. The Holders of a majority in
principal amount at maturity of the Outstanding Securities 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; provided that


                                      -77-
<PAGE>


                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or expose the Trustee to personal liability
         (as determined in the sole discretion of the Trustee), and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  SECTION 5.13. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount at maturity of the Outstanding
Securities may on behalf of the Holders of all the Securities by written notice
to the Trustee waive any past default hereunder and its consequences, except a
default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Security (including any Security which is required to
         have been purchased pursuant to an Offer to Purchase which has been
         made by the Issuer), or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected or

                  (3) arising from failure to purchase any Security tendered
         pursuant to Sections 10.13 and 10.17 of this Indenture.

                  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 impair any right consequent thereon.

                  SECTION 5.15. 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 such suit, and may assess costs against any such party litigant, in the
manner and to the extent provided in the Trust Indenture Act; provided that
neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any
suit instituted by the Issuer or the Parent Guarantor; further provided, that
the provisions of this Section 5.15 shall not apply to any suit


                                      -78-
<PAGE>


instituted by the Trustee, to any suit instituted by any Holder or group of
Holders holding more than 10% in aggregate principal amount at maturity of the
Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of, or premium, if any, or interest
on any Security on or after the respective due dates expressed in such Security.

                  SECTION 5.15. Waiver of Stay or Extension Laws. Each of the
Issuer and the Parent Guarantor 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
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and each of the Issuer and the
Parent Guarantor (to the extent that it may lawfully do so) 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.

                                   ARTICLE VI

                                   The Trustee

                  SECTION 6.01. Certain Duties and Responsibilities. (a) Except
during the continuance of an Event of Default,

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants, duties or obligations shall be read into this
         Indenture against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but 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 be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.


                                      -79-
<PAGE>


                  (b) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

                  (c) No provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own wilful misconduct, except that

                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) the 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 a majority in principal amount at maturity
         of the Outstanding Securities 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; and

                  (5) 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.

                  (d) 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 Section.

                  SECTION 6.02. Notice of Defaults. The Trustee shall give the
Holders notice of any default hereunder known to the Trustee as and to the
extent provided by the Trust Indenture Act; provided, however, that in the case
of any default of the character specified in Section 5.01(e), no


                                      -80-
<PAGE>


such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default.

                  SECTION 6.03. Certain Rights of Trustee. Subject to the
provisions of Section 6.01:

                  (a) the Trustee may conclusively rely and shall be completely
         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 believed by it to be genuine
         and to have been signed or presented by the proper party or parties;

                  (b) any request or direction of the Issuer mentioned herein
         shall be sufficiently evidenced by a Issuer Request or Issuer Order and
         any resolution of the Board of Directors may be sufficiently evidenced
         by a Board Resolution;

                  (c) 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 any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, request from the Issuer and be
         completely protected in relying upon an Officers' Certificate received
         in response to such request;

                  (d) the Trustee may consult with counsel of its selection and
         the written 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;

                  (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 offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction reasonably
         satisfactory to the Trustee;


                                      -81-
<PAGE>


                  (f) 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 may (but shall have no
         obligation to) 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 Issuer or the Parent
         Guarantor, personally or by agent or attorney;

                  (g) 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;

                  (h) the Trustee shall not be liable with respect to any action
         taken, suffered or omitted to be taken by it in accordance with the
         direction of Holders of Outstanding Securities as provided in Sections
         5.02, 5.12 and 5.13 hereof; and

                  (i) for all purposes under this Indenture, the Trustee shall
         not be deemed to have notice of any Event of Default unless a
         Responsible Officer of the Trustee has actual knowledge thereof or
         unless written notice of any event which is in fact such a default is
         received by the Trustee at the Corporate Trust Office of the Trustee,
         and such notice references the Securities and this Indenture.

                  SECTION 6.05. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Issuer, and the Trustee assumes no responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or the Securities Guarantee. The Trustee shall
not be accountable for the use or application by the Issuer of Securities or the
proceeds thereof.

                  SECTION 6.05. May Hold Securities. The Trustee, any Paying
Agent, any Security Registrar or any other agent of the Issuer, in its
individual or any other capacity, may


                                      -82-
<PAGE>


become the owner or pledgee of Securities and, subject to Sections 6.08 and
6.13, may otherwise deal with the Issuer or the Parent Guarantor with the same
rights it would have if it were not Trustee, Paying Agent, Security Registrar or
such other agent.

                  SECTION 6.06. Money Held in Trust. 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 except as otherwise agreed with the Issuer.

                  SECTION 6.07. Compensation and Reimbursement. The Issuer and
the Parent Guarantor jointly and severally agree

                  (1) to pay to the Trustee from time to time reasonable
         compensation 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);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the
         acceptance or administration of this trust, including the costs and
         expenses of enforcing this Indenture against the Issuer or the Parent
         Guarantor (including, without limitation, this Section 6.07) and of
         defending itself against any claim (whether asserted by any Holder or
         the Issuer or the Parent Guarantor) or liability in connection with the
         exercise or performance of any of its powers or duties hereunder. The
         provisions of this Section 6.07 shall survive any termination of this
         Indenture and the resignation or removal of the Trustee.

                  As security for the performance of the obligations
of the Issuer under this Section 6.07, the Trustee shall


                                      -83-
<PAGE>


have a lien prior to the Securities upon all property and funds held or
collected by the Trustee, except funds held in trust for the payment of
principal of (and premium, if any) or interest on particular Securities. The
Trustee's right to receive payment of any amounts due under this Section 6.07
shall not be subordinate to any other liability or indebtedness of the Issuer
(even though the Securities may be so subordinated).

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(h) or Section
5.01(i), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or State bankruptcy,
insolvency or other similar law.

                  The provisions of this Section shall survive the termination
of this Indenture or the earlier resignation or termination of the Trustee.

                  SECTION 6.08. Disqualification; Conflicting Interests. If the
Trustee has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign,
to the extent and in the manner provided by, and subject to the provisions of,
the Trust Indenture Act and this Indenture.

                  SECTION 6.09. Corporate Trustee Required; Eligibility. There
shall at all times be a Trustee hereunder which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000 and its Corporate Trust Office in
the Borough of Manhattan, the City of New York, New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of a Federal, State, Territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

                  SECTION 6.10. Resignation and Removal; Appointment of
Successor. (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee


                                      -85-
<PAGE>


pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 6.11, at which time the
retiring Trustee shall be fully discharged from its obligations hereunder.

                  (b) The Trustee may resign at any time by giving written
notice thereof to the Issuer. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (c) The Trustee may be removed at any time by Act of the
Holders of a majority in principal amount at maturity of the Outstanding
Securities, delivered to the Trustee and to the Issuer.

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 6.08 after
         written request therefor by the Issuer or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.09
         and shall fail to resign after written request therefor by the Issuer
         or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuer by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.15, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Issuer, by a Board Resolution, shall promptly appoint a successor
Trustee. If,


                                      -85-
<PAGE>


within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount at maturity of the Outstanding
Securities delivered to the Issuer and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Issuer. If no successor Trustee shall have been so appointed by the Issuer
or the Holders and accepted appointment in the manner hereinafter provided, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Issuer shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 1.06. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

                  SECTION 6.11. Acceptance of Appointment by Successor. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Issuer and to the retiring Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Issuer or the successor Trustee,
such retiring Trustee shall, upon payment of all sums owing to the Trustee under
Section 6.07, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Issuer shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

                  No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

                  SECTION 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the


                                      -86-
<PAGE>


Trustee 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
Trustee shall be a party, or any corporation succeeding to all or substantially
all the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, without the execution or filing of any paper or any further
act on the part of any of the parties hereto; provided that such corporation
shall be otherwise qualified and eligible under this Article. In case any
Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

                  SECTION 6.13. Preferential Collection of Claims Against Issuer
or Guarantors. If and when the Trustee shall be or become a creditor of the
Issuer or either Guarantor (or any other obligor upon the Securities), the
Trustee shall be subject to the provisions of the Trust Indenture Act regarding
the collection of claims against the Issuer or Parent Guarantor (or any such
other obligor).

                  SECTION 6.15. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to the Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 3.06, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Issuer and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant


                                      -87-
<PAGE>


to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent;
provided, such corporation shall be otherwise eligible under this Section.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Issuer. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Issuer. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Issuer and shall give notice of such
appointment in the manner provided in Section 1.06 to all Holders of Securities.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.07.

                  If an appointment is made pursuant to this Section, the
Securities may have endorsed thereon, in lieu


                                      -88-
<PAGE>


of the Trustee's certificate of authentication, an alternative certificate of
authentication in the following form:

                  This is one of the Securities referred to in the
within-mentioned Indenture.

Dated:


                                       THE CHASE MANHATTAN BANK, as
                                       Trustee,

                                         by

                  SECTION 6.15. Withholding Taxes. Notwithstanding any other
provision of this Agreement, the Trustee, as agent for the Issuer and the Parent
Guarantor, shall exclude and withhold from each payment of principal and
interest and other amounts due hereunder or under the Securities or the
Securities Guarantee 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 Securities or the Securities Guarantee, 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 Securities, that it will furnish to the Holders of the Securities
such forms or certificates as are necessary or appropriate to provide the
information described in Section 10.09(c)(i) hereof or make the declaration or
claim described in Section 10.09(c)(ii) hereof, 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 Security
appropriate documentation showing the payment thereof, together with such
additional documentary evidence as such Holders may reasonably request from time
to time.

                  In the event that the Trustee is also acting as Paying Agent,
Authenticating Agent, transfer agent, or


                                      -89-

Registrar hereunder, the rights and protections afforded to the Trustee pursuant
to this Article Six shall also be afforded to such Paying Agent, Authenticating
Agent, transfer agent, or Registrar.

                                   ARTICLE VII

Guarantor may, in a single transaction or a series of related transactions,
(except, in the case of the Subsidiary Guarantor, in any transaction or series
of related transactions as a result of which the Subsidiary Guarantor is
released from its obligations under the Securities Guarantee) (i) consolidate
with or merge into any other Person or permit any other Person to consolidate
with or merge into either Guarantor or the Issuer, or (ii) directly or
indirectly, transfer, sell, lease or otherwise dispose of all or substantially
all of its assets to any other Person, unless:

                  (1) in a transaction in which either Guarantor or the Issuer,
         as applicable, does not survive or in which either Guarantor or the
         Issuer sells, leases or otherwise disposes of all or substantially all
         of its assets to any other Person (other than, in any such case, either
         Guarantor or the Issuer), the successor entity to such Guarantor or the
         Issuer is organized under the laws of Bermuda, the United Kingdom, the
         United States of America or any State thereof or the District of
         Columbia, the British Virgin Islands, Cayman Islands, The Netherlands,
         Ireland or Jersey and shall expressly assume, by a supplemental
         indenture executed and delivered to the Trustee in form satisfactory to
         the Trustee, all of such Guarantors' or the Issuer's obligations under
         the Indenture;

                  (2) immediately before and after giving effect to such
         transaction and treating any Debt which becomes an obligation of either
         Guarantor or a Subsidiary as a result of such transaction as having
         been Incurred by such Guarantor or such Subsidiary at the time of the
         transaction, no Event of Default or event that with the passing of time
         or the giving of notice, or both, would constitute an Event of Default
         shall have occurred and be continuing;

                  (3) immediately after giving effect to such transaction, the
         Consolidated Net Worth of the Parent Guarantor (or other successor
         entity to the Parent Guarantor) is equal to or greater than that of the
         Parent Guarantor immediately prior to the transaction;

                  (5) if, as a result of any such transaction, property or
         assets of the Parent Guarantor or any Subsidiary would become subject
         to a Lien prohibited by Section 10.15, the Parent Guarantor or the
         successor entity to the Parent Guarantor shall have secured the
         Securities as required by said covenant; and

                  (5) in the event that the continuing Person is incorporated in
         a jurisdiction other than the United States or the jurisdiction in
         which such Person was incorporated immediately prior to such
         transaction, (A) the Issuer delivers to the Trustee an Opinion of
         Counsel stating that the obligations of the continuing Person under the
         Indenture are enforceable under the laws of the new jurisdiction of its
         incorporation to the same extent as the obligations of the Issuer or
         the Parent Guarantor, as the case may be, under the Indenture
         immediately prior to such transaction; (B) the continuing Person agrees
         in writing to submit to jurisdiction and appoints an agent for the
         service of process, each under terms substantially similar to the terms
         contained in the Indenture with respect to the Issuer or such
         Guarantor, as the case may be; (C) the continuing Person agrees in
         writing to pay Additional Amounts as provided under this Indenture
         under Section 10.09 with respect to the Issuer or such Guarantor, as
         the case may be, except that such Additional Amount shall relate to any
         withholding tax whatsoever regardless of any change of law (subject to
         exceptions substantially similar to those contained in Section 10.09);
         (D) the Board of Directors of the Parent Guarantor determines in good
         faith that such transaction will have no material adverse effect on any
         Holder and a Board Resolution to that effect is delivered to the
         Trustee; and (E) the principal purpose of the continuing Person being
         incorporated in such jurisdiction is to obtain tax benefits for such
         Guarantor, the Issuer, their direct and indirect stockholders or the
         Holders.

                  SECTION 8.02. Successor Substituted. Upon any consolidation of
either Guarantor or the Issuer with, or merger of either Guarantor or the Issuer
with or into, any other Person or any conveyance, transfer or lease of the
properties and assets of either Guarantor or the Issuer substantially as an
entirety in accordance with Section 8.01, the successor Person formed by such
consolidation or into which such Guarantor or the Issuer, as applicable, is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, such
Guarantor or the Issuer, as applicable, under this Indenture with the same
effect as if such successor Person had been named as such Guarantor or the
Issuer herein, and thereafter, except in the case of a lease, the predecessor
Person shall be relieved of all obligations and covenants under this Indenture
and the Securities.

         covenants of the Issuer or such Guarantor herein and in the Securities;
         or

                  (2) to add to the covenants of the Issuer or either Guarantor
         for the benefit of the Holders, or to surrender any right or power
         herein conferred upon the Issuer or either Guarantor; or

         Indenture to such extent as shall be necessary to comply with any
         requirement of the Commission in order to effect qualification of this
         Indenture under the Trust Indenture Act in connection with the issuance
         of Exchange Securities or Registered Securities or thereafter to
         maintain the qualification of this Indenture under the Trust Indenture
         Act; or

                  (5) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture which shall not be inconsistent
         with the provisions of this Indenture; provided that such action
         pursuant to this Clause (5) shall not adversely affect the interests of
         the Holders in any material respect; or

                  (6) to provide for uncertificated Securities in addition to or
         in place of certified Securities.

Security affected thereby,

                  (1) change the Stated Maturity of the principal of, or any
         installment of interest on, any Security, or reduce the principal
         amount thereof or the rate of interest thereon or any premium payable
         thereon, or change the coin or currency in which, any Security or any
         premium or interest thereon is payable, or impair the right to
         institute suit for the enforcement of any such payment on or after the
         Stated Maturity thereof (or, in the case of redemption, on or after the
         Redemption Date) or, in the case of an Offer to Purchase which has been
         made, on or after the applicable Purchase Date, or

                  (2) reduce the percentage in principal amount at maturity of
         the Outstanding Securities, the consent of whose Holders is required
         for any such supplemental indenture, or the consent of whose Holders is
         required for any waiver (of compliance with certain provisions of this

         provided for in this Indenture, or

                  (3) modify any of the provisions of this Section, Section 5.13

                  It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

                  SECTION 9.03. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.01) shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but 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.

                  SECTION 9.05. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form

                  SECTION 10.02. Maintenance of Office or Agency. The Issuer
will maintain in the Borough of Manhattan, the City of New York, New York, an
office or agency where Securities may be presented or surrendered for payment,
where Securities may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Issuer in respect of the Securities and
this Indenture may be served. The Issuer 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 Issuer 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
Corporate Trust Office of the Trustee, and the Issuer hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

                  The Issuer may also from time to time designate one or more
other offices or agencies (in or outside the Borough of Manhattan, the City of
New York, New York) where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Issuer of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York, New York for such purposes. The
Issuer 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.

                  SECTION 10.03. Money for Security Payments To Be Held in
Trust. If the Issuer shall at any time act as its own Paying Agent, it will, on
or before each due date of the principal of (and premium, if any) or interest on
any of the Securities, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
in writing of its action or failure so to act. As provided in Section 5.05, upon
any bankruptcy or reorganization proceeding relative to the Issuer, the Trustee
shall serve as the Paying Agent for the Securities.

                  Whenever the Issuer shall have one or more Paying Agents, it
will, prior to each due date of the principal of


                                      -98-
<PAGE>


(and premium, if any) or interest on any Securities, deposit with a Paying Agent
a sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Issuer will promptly notify the Trustee in writing of its
action or failure so to act. Upon any bankruptcy or reorganization proceeding
relative to the Issuer, the Trustee shall serve as the Paying Agent for the
Securities.

                  The Issuer will cause each Paying Agent other than the Trustee
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, that
such Paying Agent will:

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest on Securities in trust for the
         benefit of the Persons entitled thereto until such sums shall be paid
         to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee written notice of any default by the
         Issuer (or any other obligor upon the Securities) in the making of any
         payment of principal (and premium, if any) or interest;

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent; and

                  (5) acknowledge, accept and agree to comply in all respects
         with the provisions of this Indenture relating to the duties, rights
         and obligations of such Paying Agent.

                  The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Issuer or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Issuer or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Issuer, in trust for the payment of the principal of (and
premium, if any) or interest on any


                                      -99-
<PAGE>


Security and remaining unclaimed for two years after such principal (and
premium, if any) or interest has become due and payable shall be paid to the
Issuer on Issuer Request, or (if then held by the Issuer) shall be discharged
from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Issuer for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Issuer as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Issuer cause to be
published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, the City of New York, New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Issuer.

                  SECTION 10.05. Existence. Subject to Article Eight, the
Guarantors will do or cause to be done all things necessary to preserve and keep
in full force and effect the existence, rights (charter and statutory) and
franchises of the Guarantors, the Issuer and each of the Restricted
Subsidiaries; provided, however, that the Guarantors shall not be required to
preserve any such right or franchise if either Guarantor shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of such Guarantor, the Issuer or the Restricted Subsidiaries and that the loss
thereof is not disadvantageous in any material respect to the Holders.

                  SECTION 10.05. Maintenance of Properties. The Guarantors will
cause all properties used or useful in the conduct of their business or the
business of the Issuer or any Restricted Subsidiary to be maintained and kept in
good condition, repair and working order 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 Guarantors may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent either Guarantor from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the reasonable judgment of the Parent Guarantor, desirable
in the conduct of its business or the business of the Issuer or any Restricted
Subsidiary and not disadvantageous in any material respect to the Holders.

                  SECTION 10.06. Payment of Taxes and Other Claims. Neither
Guarantor will pay or discharge or cause to be paid or discharged, before the
same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon such Guarantor or the Issuer or any
Restricted Subsidiaries or upon the income, profits or property of such
Guarantor or the Issuer or any Restricted Subsidiaries, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of such Guarantor or the Issuer or any Restricted
Subsidiaries; provided, however, that neither Guarantor shall be required to pay
or discharge or cause to be paid or discharged any such tax, assessment, charge
or claim whose amount, applicability or validity is being contested in good
faith by appropriate proceedings.

                  SECTION 10.07. Maintenance of Insurance. The Guarantors shall,
and shall cause the Issuer and the Restricted Subsidiaries to, keep at all times
all of their properties which are of an insurable nature insured against loss or
damage with insurers believed by the Guarantors to be responsible to the extent
that property of similar character is usually so insured by corporations
similarly situated and owning like properties in accordance with good business
practice.

                  SECTION 10.08. Limitation on Consolidated Debt. The Parent
Guarantor may not, and may not permit any Restricted Subsidiary of the Parent
Guarantor to, Incur any Debt (other than the Securities and the Securities
Guarantee) unless the ratio of (i) the aggregate consolidated principal amount
of Debt (which is defined to include the accreted value of any Debt issued at a
discount) of the Parent Guarantor outstanding as of the most recent available
quarterly or annual balance sheet, after giving pro forma effect to the
Incurrence of such Debt and any other Debt Incurred since such balance sheet
date and the receipt and application of the proceeds thereof, to (ii) four (5)
times the Consolidated Cash Flow Available for Fixed Charges for the most recent
fiscal quarter next preceding the Incurrence of such Debt for which consolidated
financial statements are available, determined on a pro forma basis as if any
such Debt had been Incurred and the proceeds thereof had been applied at the
beginning of such recent fiscal quarter, would be less than 7.0 to 1.0 for such
period.

                  Notwithstanding the foregoing limitation, the Parent Guarantor
and any Restricted Subsidiary may Incur the following:

                  (i) Debt under Credit Facilities in an aggregate principal
         amount at any one time not to exceed $200


                                      -101-
<PAGE>


         million, and any renewal, extension, refinancing or refunding thereof
         in an amount which, together with any principal amount remaining
         outstanding under all Credit Facilities, does not exceed the aggregate
         principal amount outstanding under all Credit Facilities immediately
         prior to such renewal, extension, refinancing or refunding;

                  (ii) Debt owed by the Parent Guarantor to any Restricted
         Subsidiary of the Parent Guarantor or Debt owed by a Restricted
         Subsidiary of the Parent Guarantor to the Parent Guarantor or a
         Restricted Subsidiary of the Parent Guarantor; provided, however, that
         upon either (x) the transfer or other disposition by such Restricted
         Subsidiary or the Parent Guarantor of any Debt so permitted to a Person
         other than the Parent Guarantor or another Restricted Subsidiary of the
         Parent Guarantor or (y) such Restricted Subsidiary ceasing to be a
         Restricted Subsidiary, the provisions of this clause (ii) shall no
         longer be applicable to such Debt and such Debt shall be deemed to have
         been Incurred at the time of such transfer or other disposition;

                  (iii) Debt Incurred to renew, extend, refinance or refund
         (each, a "refinancing") (x) Debt outstanding at the date hereof (after
         giving effect to the Equity Clawback) or (y) Incurred pursuant to the
         first paragraph of this Section, or clause (vi) or (vii) of this
         paragraph or (z) the Securities issued on the date hereof or Securities
         exchanged therefore, in each case, in an aggregate principal amount not
         to exceed the aggregate principal amount of and accrued interest on the
         Debt so refinanced plus the amount of any premium required to be paid
         in connection with such refinancing pursuant to the terms of the Debt
         so refinanced or the amount of any premium reasonably determined by the
         Parent Guarantor as necessary to accomplish such refinancing by means
         of a tender offer or privately negotiated repurchase, plus the expenses
         of the Parent Guarantor or the Restricted Subsidiary effecting such
         refinancing incurred in connection with such refinancing; provided,
         however, that Debt the proceeds of which are used to refinance the
         Securities or Debt which is pari passu to the Securities and the
         Security Guarantee or Debt which is subordinate in right of payment to
         the Securities and the Security Guarantee shall only be permitted if
         (A) in the case of any refinancing of the Securities or Debt which is
         pari passu to the Securities and the Security Guarantee, the
         refinancing Debt is made pari passu or subordinated to the Securities
         and the Security Guarantee, and, in the case of any refinancing of
         Subordinated Debt, the


                                      -102-
<PAGE>


         refinancing Debt constitutes Subordinated Debt and (B) in any case, the
         refinancing Debt by its terms, or by the terms of any agreement or
         instrument pursuant to which such Debt is issued, does not have a final
         stated maturity prior to the final stated maturity of the Debt being
         refinanced, and the Average Life of such new Debt is at least equal to
         the remaining Average Life of the Debt being refinanced (assuming that
         such Debt being refinanced had a final stated maturity three months
         later than its actual final stated maturity);

                  (iv) Debt in an aggregate principal amount not in excess of
         (A) two (2) times the aggregate amount of the Parent Guarantor's
         Incremental Paid-in Capital minus (B) $165 million;

                  (v) Debt in an aggregate principal amount not in excess of 80%
         of the aggregate amount of accounts receivable set forth on the most
         recent unaudited quarterly or audited annual financial statements of
         the Parent Guarantor and its consolidated subsidiaries filed with the
         Commission;

                  (vi) Purchase Money Debt, which is incurred for the
         construction, acquisition and improvement of Telecommunications Assets,
         provided that the amount of such Purchase Money Debt does not exceed
         the cost of the construction, acquisition or improvement of the
         applicable Telecommunications Assets;

                  (vii) Debt consisting of Permitted Interest Rate and
         Currency Protection Agreements; and

                  (viii) Debt not otherwise permitted to be Incurred pursuant to
         clauses (i) through (vii) above, which, together with any other
         outstanding Debt Incurred pursuant to this clause (viii), has an
         aggregate principal amount not in excess of $50 million at any time
         outstanding.

                  For purposes of determining compliance with this Section, with
respect to any item of Debt, (x) in the event that such item of Debt meets the
criteria of more than one of the types of Debt the Parent Guarantor or a
Restricted Subsidiary is permitted to Incur pursuant to the foregoing clauses
(i) through (viii), the Parent Guarantor shall have the right, in its sole
discretion, to classify such item of Debt and shall only be required to include
the amount and type of such Debt under the clause permitting the Debt as so
classified and (y) any other obligation of the obligor on such Debt (or of any
other Person who could have Incurred such Debt under this Section) arising under
any Guarantee, Lien or letter of credit supporting such Debt shall be


                                      -103-
<PAGE>


disregarded to the extent that such Guarantee, Lien or letter of credit secures
the principal amount of such Debt.

                  For purposes of determining compliance with any
Dollar-denominated restriction on the Incurrence of Debt denominated in a
foreign currency, the Dollar-equivalent principal amount of such
foreign-currency-denominated Debt Incurred pursuant thereto shall be calculated
based on the relevant currency exchange rate in effect on the date that such
foreign-currency-denominated Debt was Incurred, in the case of term debt, or
first committed, in the case of revolving credit debt; provided that (x) the
Dollar-equivalent principal amount of any such Debt outstanding on the date
hereof shall be calculated based on the relevant currency exchange rate in
effect on the date hereof and (y) if such Debt is Incurred to refinance other
Debt denominated in a foreign currency, and such refinancing would cause the
applicable Dollar-denominated restriction to be exceeded if calculated at the
relevant currency exchange rate in effect on the date of such refinancing, such
Dollar denominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing Debt does not exceed the principal
amount of such Debt being refinanced. The principal amount of any Debt Incurred
to refinance other Debt, if Incurred in a different currency from the Debt being
refinanced, shall be calculated based on the currency exchange rate applicable
to the currency in which such respective Debt is denominated that is in effect
on the date of such refinancing.

                  SECTION 10.09. Additional Amounts. Payments made by the Issuer
or the Guarantors pursuant to the Securities or the Securities Guarantee will be
made without withholding or deduction for taxes unless required by law. In the
event of (x) any change that becomes effective after the date hereof in the laws
of the U.K. or Bermuda or of any political subdivision or taxing authority
thereof or therein or any change in the interpretation or administration thereof
or (y) a failure by the Issuer to list and maintain a listing of the Securities
on a "recognized stock exchange" (within the meaning of Section 851 of the U.K.
Income and Corporation Taxes Act 1988) prior to the first date upon which
interest is required to be paid hereunder (a "Listing Failure"), the effect of
which is to require the withholding or deduction by the Issuer or the Guarantors
pursuant to the Securities or the Securities Guarantee, respectively, of any
amount for taxes that would not have been required to be withheld or deducted
absent such change or Listing Failure, as the case may be, the Issuer or the
Guarantors will pay, to the extent they may then lawfully do so, such additional
amounts ("Additional Amounts") as may be necessary in order that every net
payment of the principal of and interest on the Securities, after deduction for
withholding for or on


                                      -105-
<PAGE>


account of any future tax, assessment or other governmental charge will not be
less than the amount provided for in the Securities to be then due and payable;
provided, however, that the foregoing obligation to pay Additional Amounts shall
not apply in respect of:

                  (i) any tax, withholding, assessment or other governmental
         charge which would not have been imposed but for (x) the existence of
         any present or former connection between such holder (or between a
         fiduciary, settlor, beneficiary, member or shareholder of, or possessor
         of a power over, such holder, if such holder is an estate, trust,
         partnership or corporation) and the U.K. or Bermuda or any political
         subdivision or taxing authority thereof including, without limitation,
         such holder (or such fiduciary, settlor, beneficiary, member,
         shareholder or possessor) being or having been a citizen or resident
         thereof or being or having been present or engaged in trade or business
         therein or having or having had a permanent establishment therein or
         (y) the presentation of a Security or a Securities Guarantee (where
         presentation is required) for payment on a date more than 30 days after
         the date on which such payment became due and payable or the date on
         which payment thereof is duly provided for, whichever occurs later,
         except for Additional Amounts with respect to Taxes that would have
         been imposed had the holder presented the Security for payment within
         such 30-day period;

                  (ii) any estate, inheritance, gift, sale, transfer
         or personal property tax;

                  (iii) any tax, assessment or other governmental charge that is
         withheld by reason of the failure to timely comply by the holder or the
         beneficial owner of the Security with a request in writing of the
         Issuer or the Parent Guarantor (which request shall be furnished to the
         Trustee) (x) to provide information concerning the nationality,
         residence or identity of the holder or such beneficial owner or (y) to
         make any declaration or other similar claim or satisfy any information
         or reporting requirement, which, in the case of (x) or (y), is required
         or imposed by a statute, treaty, regulation or administrative practice
         of the taxing or domicile jurisdiction as a precondition to exemption
         from or reduction of all or part of such tax, assessment or other
         governmental charge; provided, however, that this clause (iii) shall
         not apply to limit the Issuer's or Guarantors' obligation to pay
         Additional Amounts if the completing and filing of the information
         described in subclause (x) or the declaration or other claim described
         in subclause (y)


                                      -105-
<PAGE>


         would be materially more onerous in form, in procedure or in substance
         of information disclosed, in comparison to the information reporting
         requirements imposed under U.S. tax law with respect to Forms 1001, W-8
         and W-9; or

                  (iv) any tax, withholding, assessment or other governmental
         charge resulting from a Listing Failure with respect to any Security
         issued in the form of a Definitive Security pursuant to the terms of
         the Deposit Agreement and this Indenture; or

                  (v) any combination of items (i), (ii), (iii) and (iv) above;
         nor shall Additional Amounts be paid with respect to any payment of the
         principal of, or any interest on, any Security or Securities Guarantee
         to any holder who is not the sole beneficial owner of such Security or
         Securities Guarantee or is a fiduciary or partnership, but only to the
         extent that a beneficial owner, a beneficiary or a settlor with respect
         to a fiduciary or a member of the partnership would not have been
         entitled to the payment of the Additional Amount had the beneficial
         owner, beneficiary, settlor or member of such partnership received
         directly its beneficial or distributive share of the payment.

                  At least 30 days prior to each date on which any payment under
or with respect to the Securities is due and payable, if the Issuer or the
Guarantors will be obligated to pay Additional Amounts with respect to such
payment, the Issuer or the Guarantors will deliver to the Trustee an Officer's
Certificate stating the fact that such Additional Amounts will be payable and
the amounts so payable and will set forth such other information necessary to
enable the Trustee to pay such Additional Amounts to Holders on the payment
date. Whenever in this Indenture there is mentioned, in any context, the payment
of principal (and premium, if any), Redemption Price, interest or any other
amount payable under or with respect to any Security, such mention shall be
deemed to include mention of the payment of Additional Amounts to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof.

                  SECTION 10.10. Limitation on Restricted Payments. The Parent
Guarantor (i) may not, and will not permit any Restricted Subsidiary, directly
or indirectly, to declare or pay any dividend, or make any distribution, in
respect of its Capital Stock or to the holders thereof, excluding (x) any
dividends or distributions payable solely in shares of its Capital Stock (other
than Disqualified Stock) or in options, warrants or other rights to acquire its
Capital Stock (other than Disqualified Stock), (y) any dividends


                                      -106-
<PAGE>


paid to the Parent Guarantor or a Restricted Subsidiary, or (z) pro rata
dividends paid on shares of Common Stock of Restricted Subsidiaries, (ii) may
not, and may not permit any Restricted Subsidiary to, purchase, redeem, or
otherwise retire or acquire for value (a) any Capital Stock of the Parent
Guarantor or any Related Person of the Parent Guarantor (other than a permitted
refinancing) or (b) any options, warrants or rights to purchase or acquire
shares of Capital Stock of the Parent Guarantor or any Related Person of the
Parent Guarantor or any securities convertible or exchangeable into shares of
Capital Stock of the Parent Guarantor or any Related Person of the Parent
Guarantor (other than a permitted refinancing), (iii) may not make, or permit
any Restricted Subsidiary to make, any Investment, except for Permitted
Investments, and (iv) may not, and may not permit any Restricted Subsidiary to,
redeem, defease, repurchase, retire or otherwise acquire or retire for value,
prior to any scheduled maturity, repayment or sinking fund payment, Debt of the
Guarantors or the Issuer which is subordinate in right of payment to the
Securities or the Securities Guarantee (each of clauses (i) through (iv) being a
"Restricted Payment") if: (1) an Event of Default, or an event that with the
passing of time or the giving of notice, or both, would constitute an Event of
Default, shall have occurred and be continuing, or (2) except with respect to
Investments, upon giving effect to such Restricted Payment, the Parent Guarantor
could not Incur at least $1.00 of additional Debt pursuant to the first
paragraph of Section 10.08, or (3) upon giving effect to such Restricted
Payment, the aggregate of all Restricted Payments from the date hereof exceeds
the sum of: (a)(x) Consolidated Cash Flow Available for Fixed Charges since the
end of the last full fiscal quarter prior to the date hereof through the last
day of the last full fiscal quarter ending immediately preceding the date of
such Restricted Payment (the "Calculation Period") minus (y) 1.5 times
Consolidated Interest Expense for the Calculation Period plus (b) an amount
equal to the net reduction in Investments (other than reductions in Permitted
Investments) in any Person resulting from payments of interest on Debt,
dividends, repayments of loans or advances, or other transfers of assets, in
each case to the Parent Guarantor or any Restricted Subsidiary or from the Net
Cash Proceeds from the sale of any such Investment (except, in each case, to the
extent any such payment or proceeds are included in the calculation of
Consolidated Cash Flow Available for Fixed Charges for the Calculation Period),
or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
(valued in each case as provided in the definition of Investment), not to
exceed, in each case, the amount of Investments previously made by the Parent
Guarantor or any Restricted Subsidiary in such Person or Unrestricted Subsidiary
plus (c) an amount equal to the aggregate net proceeds received after the date


                                      -107-
<PAGE>


hereof, including the fair market value of property other than cash (determined
in good faith by the Board of Directors as evidenced by a resolution of the
Board of Directors filed with the Trustee), as capital contributions to the
Parent Guarantor or from the issuance (other than to a Subsidiary) of Capital
Stock (other than Disqualified Stock) of the Parent Guarantor and warrants,
rights or options on Capital Stock (other than Disqualified Stock) of the Parent
Guarantor and the principal amount at maturity of Debt of the Parent Guarantor
or any Restricted Subsidiary that has been converted into Capital Stock (other
than Disqualified Stock and other than by a Subsidiary) of the Parent Guarantor
after the date hereof plus (d) $30 million.

                  Notwithstanding the foregoing, (i) the Parent Guarantor may
pay any dividend on Capital Stock of any class of the Parent Guarantor within 60
days after the declaration thereof if, on the date when the dividend was
declared, the Parent Guarantor could have paid such dividend in accordance with
the foregoing provisions, (ii) the Parent Guarantor may make acquisitions of a
minority equity interest in entities engaged in the Telecommunications Business;
provided that (A) the acquisition of a majority equity interest in such entities
is not then permitted or practicable under applicable law without regulatory
consent or change of law, (B) the Board of Directors of the Parent Guarantor
determines in good faith that there is a substantial probability that such
approval or change of law will be obtained, (C) the Parent Guarantor or one of
its Restricted Subsidiaries has the right to acquire Capital Stock representing
a majority of the voting power of the Voting Stock of such entity upon receipt
of regulatory consent or change of law and does acquire such Voting Stock
reasonably promptly upon receipt of such consent or change of law and (D) in the
event that such consent or change of law has not been obtained within 18 months
of funding such Investment, the Parent Guarantor or one of its Restricted
Subsidiaries has the right to sell such minority equity interest to the Person
from whom it acquired such interest, for consideration consisting of the
consideration originally paid by the Parent Guarantor and its Restricted
Subsidiaries for such minority equity interest; (iii) the Parent Guarantor may
repurchase any shares of its Common Stock or options to acquire its Common Stock
from Persons who were formerly directors, officers or employees of the Parent
Guarantor or any of its Subsidiaries, provided that the aggregate amount of all
such repurchases made pursuant to this clause (iii) shall not exceed $6 million,
plus the aggregate cash proceeds received by the Parent Guarantor since the date
hereof from issuances of its Common Stock or options to acquire its Common Stock
to directors, officers and employees of the Parent Guarantor or any of its
Subsidiaries, (iv) the Parent Guarantor or a Restricted


                                      -108-
<PAGE>


Subsidiary may redeem, defease, repurchase, retire or otherwise acquire or
retire for value Debt of the Guarantors or the Issuer which is subordinated in
right of payment to the Securities or the Security Guarantees, as the case may
be, in exchange for, or out of the proceeds of a substantially concurrent sale
(other than to a Subsidiary) of, Capital Stock (other than Disqualified Stock of
the Parent Guarantor) or in a refinancing that satisfies the requirements of
clause (iii) of the second paragraph of Section 10.08, (v) the Parent Guarantor
and its Restricted Subsidiaries may retire or repurchase any Capital Stock of
the Parent Guarantor or of any Subsidiary of the Parent Guarantor in exchange
for, or out of the proceeds of the substantially concurrent sale (other than to
a Subsidiary of the Parent Guarantor) of, Capital Stock (other than Disqualified
Stock) of the Parent Guarantor or such Restricted Subsidiary and (vi) the Parent
Guarantor or a Restricted Subsidiary may make payments or distributions to
dissenting stockholders pursuant to applicable law or pursuant to or in
connection with a transaction governed by the provisions of Article VIII hereof,
provided that the number of shares as to which dissent or appraisal rights are
exercised and such payments or distributions are being made does not exceed 1%
of the total number of shares of all classes for which such rights are
exercisable.

                  SECTION 10.11. Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries. The Parent Guarantor may not,
and may not permit any Restricted Subsidiary to, directly or indirectly, create
or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary of the
Parent Guarantor (i) to pay dividends (in cash or otherwise) or make any other
distributions in respect of its Capital Stock owned by the Parent Guarantor or
any other Restricted Subsidiary of the Parent Guarantor or pay any Debt or other
obligation owed to the Parent Guarantor or any other Restricted Subsidiary; (ii)
to make loans or advances to the Parent Guarantor or any other Restricted
Subsidiary; or (iii) to transfer any of its property or assets to the Parent
Guarantor or any other Restricted Subsidiary.

                  Notwithstanding the foregoing, the Parent Guarantor may, and
may permit any Restricted Subsidiary to, suffer to exist any such encumbrance or
restriction (a) pursuant to any agreement in effect on the date hereof; (b)
pursuant to an agreement relating to any Acquired Debt, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person so acquired and was not Incurred in anticipation
of such Person being acquired; (c) pursuant to an agreement effecting a renewal,
refunding or extension of


                                      -109-
<PAGE>


Debt Incurred pursuant to an agreement referred to in clause (a) or (b) above;
provided, however, that the provisions contained in such renewal, refunding or
extension agreement relating to such encumbrance or restriction are no more
restrictive in any material respect than the provisions contained in the
agreement the subject thereof; (d) in the case of clause (iii) in the above
paragraph, contained in any security agreement (including a Capital Lease
Obligation) securing Debt of the Parent Guarantor or a Restricted Subsidiary
otherwise permitted hereunder, but only to the extent such restrictions restrict
the transfer of the property subject to such security agreement; (e) in the case
of clause (iii) in the above paragraph, with respect to customary nonassignment
provisions entered into in the ordinary course of business in leases and other
agreements; (f) with respect to a Restricted Subsidiary of the Parent Guarantor
imposed pursuant to an agreement which has been entered into for the sale or
disposition of all or substantially all of the Capital Stock or assets of such
Restricted Subsidiary, provided that (x) the consummation of such transaction
would not result in an Event of Default or an event that, with the passing of
time or the giving of notice or both, would constitute an Event of Default, (y)
such restriction terminates if such transaction is not consummated and (z) the
consummation or abandonment of such transaction occurs within one year of the
date such agreement was entered into; (g) pursuant to applicable law or required
by any regulatory authority having jurisdiction over the Parent Guarantor or any
Subsidiary; (h) pursuant to this Indenture and the Securities; (i) constituting
a Lien otherwise permitted pursuant to Section 10.15; and (j) other encumbrances
or restrictions that are not materially more restrictive than customary
provisions in comparable financings provided that each of the Issuer and the
Guarantors provides an Officer's Certificate to the Trustee to the effect that
in the opinion of the signers of such certificate such encumbrances or
restrictions will not materially impact the Issuer's and the Guarantors' ability
to make scheduled payments of interest and principal under the Securities.

                  SECTION 10.12. Limitation on Transactions with Affiliates and
Related Persons. The Parent Guarantor 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
Related Person or with any Affiliate of the Parent Guarantor or any Restricted
Subsidiary, except upon fair and reasonable terms no less favorable to the
Parent Guarantor or such Restricted Subsidiary than could be obtained, at the
time of such transaction or, if such transaction is pursuant to a written


                                      -110-
<PAGE>


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 a Related Person
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 Parent Guarantor or a Restricted
Subsidiary delivers to the Trustee a written opinion of a nationally recognized
investment banking firm (or a subsidiary or affiliate thereof) in the United
States stating that the transaction is fair to the Parent Guarantor or such
Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Parent Guarantor and any of its Wholly Owned Restricted
Subsidiaries or solely between Wholly Owned Restricted Subsidiaries; and (iii)
any payments or other transactions pursuant to any tax-sharing agreement between
the Parent Guarantor and any other Person with which the Parent Guarantor files
a consolidated tax return or with which the Parent Guarantor is part of a
consolidated group for tax purposes. Notwithstanding the foregoing, any
transaction covered by the first paragraph of this Section and not covered by
clauses (ii) through (iii) of this paragraph must be approved or determined to
be fair in the manner provided for in clause (i)(A) or (B) above unless the
aggregate amount of such transaction is less than $5 million in value.

                  SECTION 10.13. Limitation on Asset Dispositions. (a) The
Parent Guarantor may not, and may not permit any Restricted Subsidiary of the
Parent Guarantor to, make any Asset Disposition in one or more related
transactions unless: (i) the Parent Guarantor or the Restricted Subsidiary, as
the case may be, receives consideration for such disposition at least equal to
the fair market value for the assets sold or disposed of as determined by the
Board of Directors in good faith and, in the case of an Asset Disposition in an
amount greater than $5 million, evidenced by a resolution of the Board of
Directors filed with the Trustee; and (ii) at least 75% of the consideration for
such disposition consists of (1) cash or readily marketable cash equivalents or
the assumption of Debt of the Guarantors (other than Debt that is subordinated
to the Securities and the Securities Guarantee) or of a Restricted Subsidiary
and release from all liability on the Debt assumed, or (2) Telecommunications
Assets. However, none of the provisions of Section 10.13 shall apply to the
issuance or sale of capital stock of (x) deltathree.com, (y) RSL Australia or
(z) RSL Spain, in each case, made in compliance with clause (v) of Section
10.15. In the event and to the extent that the Net Available Proceeds received
by the Parent Guarantor or any of its Restricted Subsidiaries from one or more
Asset Dispositions occurring on or after the


                                      -111-
<PAGE>


date hereof in any period of 12 consecutive months exceed 10% of Consolidated
Tangible Assets (determined as of the date closest to the commencement of such
12-month period for which a consolidated balance sheet of the Parent Guarantor
and its subsidiaries have been filed with the Commission), then the Parent
Guarantor or the Issuer shall or shall cause the relevant Restricted Subsidiary
to (i) within 12 months after the date Net Available Proceeds so received exceed
10% of Consolidated Tangible Assets (A) apply an amount equal to such excess Net
Available Proceeds to permanently repay unsubordinated Debt of the Parent
Guarantor or any Restricted Subsidiary providing a Subsidiary Guarantee pursuant
to Section 10.15 or Debt of any other Restricted Subsidiary, in each case owing
to a Person other than the Parent Guarantor or any of its Restricted
Subsidiaries or (B) invest an equal amount, or the amount not so applied
pursuant to clause (A) (or enter into a definitive agreement committing to so
invest within 12 months after the date of such agreement), in Telecommunications
Assets and (ii) apply (no later than the end of the 12-month period referred to
in clause (i)) such excess Net Available Proceeds (to the extent not applied
pursuant to clause (i)) as provided in the paragraph (b) below. The amount of
such excess Net Available Proceeds required to be applied (or to be committed to
be 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".

                  (b) 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 totals at least $10 million, the Issuer shall
repay any Debt of the Parent Guarantor or any Restricted Subsidiary to the
extent the terms of such Debt require repayment prior to an Offer to Purchase
being made hereunder (including by way of an offer to purchase to the holders of
such Debt, if so required). To the extent there are Excess Proceeds after such
repayment (or offer to purchase), the Issuer must commence, not later than the
fifteenth Business Day of such month (or if later, the fifteenth Business Day
after the expiration of any such required offer to purchase), and consummate an
Offer to Purchase from the holders of the Securities on a pro rata basis an
aggregate principal amount of Securities on the relevant Payment Date equal to
the Excess Proceeds on such date not applied or to be applied pursuant to the
first sentence of this paragraph (b), at a purchase price equal to 100% of the
principal amount of the Securities, plus, in each case, accrued interest (if
any) to but excluding the Payment Date and, to the extent required by the terms
thereof, any other Debt of the Parent Guarantor that is pari passu with the
Securities at a price no greater than 100% of the principal amount


                                      -112-
<PAGE>


thereof plus accrued interest to but excluding the date of purchase (or 100% of
the accreted value in the case of original issue discount Debt). To the extent
there are any remaining Excess Proceeds following the completion of the Offer to
Purchase, the Issuer must repay such other Debt of the Parent Guarantor or Debt
of a Restricted Subsidiary of the Parent Guarantor, to the extent permitted
under the terms thereof and, to the extent there are any remaining Excess
Proceeds after such repayment, the Issuer shall apply such amount to any other
use as determined by the Issuer which is not otherwise prohibited by this
Indenture.

                  SECTION 10.15. Limitation on Issuances and Sales of Capital
Stock of Restricted Subsidiaries. The Parent Guarantor may not, and may not
permit any Restricted Subsidiary of the Parent Guarantor to, issue, transfer,
convey, sell or otherwise dispose of any shares of Capital Stock of a Restricted
Subsidiary of the Parent Guarantor or securities convertible or exchangeable
into, or options, warrants, rights or any other interest with respect to,
Capital Stock of a Restricted Subsidiary of the Parent Guarantor to any Person
other than the Parent Guarantor or a Wholly Owned Restricted Subsidiary of the
Parent Guarantor except (i) a sale of all of the Capital Stock of such
Restricted Subsidiary owned by the Parent Guarantor and any Restricted
Subsidiary of the Parent Guarantor that complies with Section 10.13 above to the
extent such Section applies, (ii) if required, the issuance, transfer,
conveyance, sale or other disposition of directors' qualifying shares, (iii)
Disqualified Stock issued in exchange for, or upon conversion of, or the
proceeds of the issuance of which are used to redeem, refinance, replace or
refund shares of Disqualified Stock of such Restricted Subsidiary; provided that
the amounts of the redemption obligations of such Disqualified Stock shall not
exceed the amounts of the redemption obligations of, and such Disqualified Stock
shall have redemption obligations no earlier than those required by, the
Disqualified Stock being exchanged, converted, redeemed, refinanced, replaced or
refunded and (iv) issuances of not more than 59% of the voting stock and equity
interest in a Restricted Subsidiary engaged in the Telecommunications Business
(1) in connection with the acquisition of such Restricted Subsidiary or of
Telecommunications Assets acquired or to be acquired by the Parent Guarantor or
a Restricted Subsidiary or (2) to a Strategic Investor; provided, that the
Parent Guarantor complies with Section 10.13 above to the extent such Section
applies and (v) issuances or sales of capital stock of each of deltathree.com,
RSL Australia and RSL Spain, including pursuant to stock option plans or other
equity compensation and incentive plans established for each of their respective
employees, directors, and consultants, so long as


                                      -113-
<PAGE>


immediately after giving effect to such issuances and sales, the issuer of such
capital stock is a Restricted Subsidiary.

                  SECTION 10.15. Limitation on Liens. The Parent Guarantor may
not, and may not permit any Restricted Subsidiary of the Parent Guarantor to,
Incur or suffer to exist any Lien on or with respect to any property or assets
now owned or hereafter acquired to secure any Debt without making, or causing
such Restricted Subsidiary to make, effective provision for securing the
Securities (x) equally and ratably with such Debt as to such property for so
long as such Debt will be so secured or (y) in the event such Debt is Debt of
the Parent Guarantor which is subordinate in right of payment to the Securities,
prior to such Debt as to such property for so long as such Debt will be so
secured.

                  The foregoing restrictions shall not apply to: (i) Liens
existing on the date hereof and securing Debt outstanding on the date hereof;
(ii) Liens securing Debt outstanding or available under all Credit Facilities to
the extent such Debt is permitted under clause (i) of the second paragraph of
Section 10.08; (iii) Liens in favor of the Parent Guarantor or any Restricted
Subsidiary of the Parent Guarantor; (iv) Liens on real or personal property of
the Parent Guarantor or a Restricted Subsidiary of the Parent Guarantor
acquired, constructed or constituting improvements made after the date of
original issuance of the Securities to secure Purchase Money Debt which is
Incurred for the construction, acquisition and improvement of Telecommunications
Assets and is otherwise permitted under this Indenture; provided, however, that
(a) the principal amount of any Debt secured by such a Lien does not exceed 100%
of such purchase price or cost of construction or improvement of the property
subject to such Liens, (b) such Lien attaches to such property prior to, at the
time of or within 180 days after the acquisition, completion of construction or
commencement of operation of such property and (c) such Lien does not extend to
or cover any property other than the specific item of property (or portion
thereof) acquired, constructed or constituting the improvements made with the
proceeds of such Purchase Money Debt; (v) Liens to secure Acquired Debt;
provided, however, that (a) such Lien attaches to the acquired asset prior to
the time of the acquisition of such asset and (b) such Lien does not extend to
or cover any other asset; (vi) Liens to secure Debt Incurred to extend, renew,
refinance or refund (or successive extensions, renewals, refinancings or
refundings), in whole or in part, Debt secured by any Lien referred to in the
foregoing clauses (i), (ii), (iv) and (v) so long as the principal amount of
Debt so secured is not increased except as otherwise permitted under clause
(iii) of the second paragraph of Section 10.08 and, in the case of Liens to
secure Debt incurred to extend, renew, refinance or


                                      -115-
<PAGE>


refund Debt secured by a Lien referred to in the foregoing clause (i), (iv) or
(v), such Liens do not extend to any other property; and (vii) Permitted Liens.

                  SECTION 10.16. Limitation on Issuance of Guarantees of Debt by
Restricted Subsidiaries. The Parent Guarantor will not permit any Restricted
Subsidiary, directly or indirectly, to incur any Guarantee of any Debt of the
Guarantors or the Issuer unless such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture providing for a Guarantee by such
Subsidiary of the Securities; any Subsidiary Guarantee by such Subsidiary of the
Securities (x) will be senior in right of payment to any Guarantee of
Subordinated Debt of the Guarantors or the Issuer and (y) will be pari passu
with or senior to any Guarantee of any other Debt of the Guarantors or the
Issuer.

                  Notwithstanding the foregoing, any Subsidiary Guarantee 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 Parent Guarantor, of all of the Parent Guarantor'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 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 10.17. Change of Control. (a) Unless the Issuer has
heretofore exercised its right to redeem all of the Securities in accordance
with the terms of this Indenture and the Securities, upon the occurrence of a
Change of Control (as defined below), each Holder of a Security shall have the
right to have such Security repurchased by the Issuer on the terms and
conditions precedent set forth in this Section 10.17 and otherwise in this
Indenture. The Issuer shall, within 30 days following the date of the
consummation of a transaction resulting in a Change of Control, mail an Offer
with respect to an Offer to Purchase all Outstanding Securities at a purchase
price equal to 101% of their principal amount plus accrued interest to but
excluding the date of purchase. Installments of interest (including Special
Interest) whose Stated Maturity is on or prior to the Purchase Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.07. Each Holder
shall be entitled to tender all or any portion of the Securities owned by such
Holder pursuant to the Offer to Purchase,


                                      -115-
<PAGE>


subject to the requirement that any portion of a Security tendered must be
tendered in an integral multiple of $1,000 principal amount at maturity.

                  (b) The Issuer and Trustee shall perform their respective
obligations specified in the Offer for the Offer to Purchase. Prior to the
Purchase Date, the Issuer shall (i) accept for payment Securities or portions
thereof tendered pursuant to the Offer, (ii) deposit with the Paying Agent (or,
if the Issuer is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) money sufficient to pay the purchase price of all
Securities or portions thereof so accepted and (iii) deliver or cause to be
delivered to the Trustee all Securities so accepted together with an Officers'
Certificate stating the Securities or portions thereof accepted for payment by
the Issuer. The Paying Agent shall promptly mail or deliver to Holders of
Securities so accepted payment in an amount equal to the purchase price, and the
Trustee shall promptly authenticate and mail or deliver to such Holders a new
Security or Securities equal in principal amount to any unpurchased portion of
the Security surrendered as requested by the Holder. Any Security not accepted
for payment shall be promptly mailed or delivered by the Issuer to the Holder
thereof.

                  (c) A "Change of Control" shall be deemed to have occurred in
the event that, after the date of this Indenture, either (i) a "person" or
"group" (within the meaning of Sections 13(d) and 15(d)(2) of the Exchange Act)
becomes the ultimate "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act) of more than 35% of the total voting power of the Voting Stock of
the Parent Guarantor, on a fully diluted basis, and such ownership is greater
than the amount of voting power of the Voting Stock of the Parent Guarantor, on
a fully diluted basis, held by the Existing Stockholders and their Affiliates on
such date; (ii) individuals who on the date of this Indenture constitute the
Board of Directors (together with any new directors whose election by the Board
of Directors or whose nomination for election by the Parent Guarantor's
stockholders was approved by a vote of at least two-thirds of the members of the
Board of Directors then in office who either were members of the Board of
Directors on the date of this Indenture or whose election or nomination for
election was previously so approved) cease for any reason to constitute a
majority of the members of the Board of Directors then in office; or (iii) all
of the Common Stock of the Issuer is not beneficially owned by the Parent
Guarantor (other than directors' qualifying shares).

                  (d) In the event that the Issuer makes an Offer to Purchase
the Securities, the Issuer and the Guarantors


                                      -116-
<PAGE>


shall comply with any applicable securities laws and regulations, including any
applicable requirements of Section 15(e) of, and Rule 15e-1 under, the
Securities Exchange Act.

                  SECTION 10.18. Provision of Financial Information. The
Guarantors and the Issuer have agreed that, for so long as any Securities remain
Outstanding, each will furnish to the holders of the Securities and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 155A(d)(5) under the
Securities Act. In addition, the Guarantors and the Issuer will file with the
Trustee within 15 days after it files them with the Commission copies of the
annual and quarterly reports and the information, documents, and other reports
that the Guarantors or the Issuer is required to file with the Commission
pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC Reports"). In the
event either Guarantor or the Issuer shall cease to be required to file SEC
Reports pursuant to the Exchange Act, such Guarantor and the Issuer will
nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing) and the Trustee. The Guarantors and
the Issuer will furnish copies of the SEC Reports to the holders of Securities
at the time the Guarantors or the Issuer is required to file the same with the
Trustee and will make such information available to investors who request it in
writing.

                  SECTION 10.19. Statement by Officers as to Default. (a) The
Issuer and the Guarantors will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Parent Guarantor ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof either Guarantor or the Issuer is in default in the performance
and observance of any of the terms, provisions and conditions of Sections 10.05
to 10.18, inclusive, and if either Guarantor or the Issuer shall be in default,
specifying all such defaults and the nature and status thereof of which they may
have knowledge.

                  (b) The Issuer and the Guarantors shall deliver to the
Trustee, as soon as possible and in any event within 10 days after the Issuer or
either Guarantor becomes aware of the occurrence of an 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 Issuer or such Guarantor proposes to
take with respect thereto.

<PAGE>


                  SECTION 10.20. Waiver of Certain Covenants. The Issuer, the
Parent Guarantor or the Subsidiary Guarantor, as applicable, may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 10.05 to 10.17, inclusive, if before or after the time for such
compliance the Holders of at least a majority in aggregate principal amount at
maturity of the Outstanding Securities shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Issuer and the Guarantors
and the duties of the Trustee in respect of any such covenant or condition shall
remain in full force and effect.

                  SECTION 10.21. Paying Agent. The Issuer shall not authorize or
designate any Person (including the Trustee) as a Paying Agent hereunder unless
such Person is located outside of the United Kingdom.

                                   ARTICLE XI

                            Redemption of Securities

                  SECTION 11.01. Right of Redemption. (a) At any time prior to
March 1, 2003, in the event that the Parent Guarantor receives net cash proceeds
from the public or private sale of its Common Stock (other than Disqualified
Stock), the Issuer (to the extent it receives such proceeds and has not used
such proceeds, directly or indirectly, to redeem or repurchase other securities
pursuant to optional redemption provisions) may, at its option, apply an amount
equal to any such net cash proceeds to redeem, from time to time, Securities in
a principal amount at maturity of up to an aggregate amount equal to 33 1/3% of
the original aggregate principal amount at maturity of the Securities; provided,
however, that Securities in an amount equal to at least 66 2/3% of the original
aggregate principal amount at maturity of the Securities remain Outstanding
after each redemption. Each redemption must occur on a Redemption Date within
180 days of the related sale and upon not less than 30 nor more than 60 days'
notice by mail to each Holder of Securities to be redeemed at such Holder's
address appearing in the Security Register, in amounts of $1,000 or an integral
multiple of $1,000 at a Redemption Price of 112.875% of the principal amount of
the Securities plus accrued interest to but excluding the Redemption Date
(subject to, in the case of a Global Security in bearer form, the right of the
Holder thereof and, in the case of Definitive Securities, the right of Holders
of record on the relevant Regular Record Date, to receive Interest due on an


                                      -118-
<PAGE>


Interest Payment Date that is on or prior to the Redemption Date).

                  (b) In the event that (i) the Guarantors or the Issuer has
become or would become obligated to pay any Additional Amounts as a result of
(x) changes affecting withholding tax laws or (y) a Listing Failure (as defined
herein) provided that the Issuer has used reasonable best efforts to list and
maintain the listing of the Securities on a "recognized stock exchange" (within
the meaning of Section 851 of the U.K. Income and Corporation Taxes Act 1988)
(as provided for in Section 10.09), and (ii) the Guarantors and the Issuer are
unable to avoid the requirement to pay such Additional Amounts by taking
reasonable measures available to them (including, without limitation, the
Guarantors making payments directly to holders under the Securities Guarantee,
unless such payment is likely to result in adverse consequences to the Issuer or
either Guarantor), then the Issuer may redeem all, but not less than all, of the
Securities at any time at 100% of the principal amount thereof on the Redemption
Date, together with accrued interest thereon, if any, to but excluding the
Redemption Date (subject to, in the case of a Global Security in bearer form,
the right of the Holder thereof and, in the case of Definitive Securities, the
right of Holders of record on the relevant Regular Record Date, to receive
Interest due on an Interest Payment Date that is on or prior to the Redemption
Date). Prior to the publication of the notice of redemption in accordance with
the foregoing, the Issuer shall deliver to the Trustee an officer's certificate
stating that the Issuer is entitled to effect such redemption based on a written
opinion of independent tax counsel or accounting firm reasonably satisfactory to
the Trustee.

                  (c) The Securities further may be redeemed, as a whole or in
part, at the election of the Issuer, at any time on or after March 1, 2005 and
prior to maturity, upon not less than 30 nor more than 60 days' notice by mail
to each Holder of Securities to be redeemed at such Holder's address appearing
in the Security Register, in amounts of $1,000 or an integral multiple of
$1,000, at the Redemption Prices specified in the form of Security hereinbefore
set forth, together with accrued interest to but excluding the Redemption Date
(subject to, in the case of a Global Security in bearer form, the right of the
Holder thereof and, in the case of Definitive Securities, the right of Holders
of record on the relevant Regular Record Date, to receive Interest due on an
Interest Payment Date that is on or prior to the Redemption Date).

                  SECTION 11.02. Applicability of Article. Redemption of
Securities at the election of the Issuer, as


                                      -119-
<PAGE>


permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

                  SECTION 11.03. Election To Redeem; Notice to Trustee. The
election of the Issuer to redeem any Securities pursuant to Section 11.01 shall
be evidenced by a Board Resolution. In case of any redemption at the election of
the Issuer of less than all the Securities, the Issuer shall, at least 5 days
prior to giving notice of such redemption pursuant to Section 11.05 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of Securities to be
redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Issuer shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

                  SECTION 11.05. Securities To Be Redeemed Pro Rata. If less
than all the Securities are to be redeemed in any redemption, the Securities to
be redeemed shall be selected by the Trustee by prorating, as nearly as may be
practicable, the principal amount at maturity of Securities to be redeemed. In
any proration pursuant to this Section, the Trustee shall make such adjustments,
reallocations and eliminations as it shall deem proper to the end that the
principal amount at maturity of Securities so prorated shall be $1,000 or a
multiple thereof, by increasing or decreasing or eliminating the amount which
would be allocable to any Holder on the basis of exact proportion by an amount
not exceeding $1,000. The Trustee in its discretion may determine the particular
Securities (if there are more than one) registered in the name of any Holder
which are to be redeemed, in whole or in part. The Trustee shall incur no
liabilities for any selection made pursuant to this Section 11.05.

                  The Trustee shall promptly notify the Issuer and each Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount at
maturity thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal amount at maturity of such Securities
which has been or is to be redeemed.

                  SECTION 11.05. Notice of Redemption. Notice of redemption
shall be given by first-class mail, postage prepaid, mailed not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Securities to
be redeemed, at such Holder's address appearing in the Security Register.

                  All notices of redemption shall state:

                            (1) the Redemption Date,

                            (2) the Redemption Price,

                  (3) whether the redemption is being made pursuant to Section
         11.01(a), (b) or (c) and, if being made pursuant to Section 11.01(a) or
         (b), a brief statement setting forth the Issuer's right to effect such
         redemption and the Issuer's basis therefor,

                  (5) if less than all the Outstanding Securities are to be
         redeemed, the identification (and, in the case of partial redemption of
         any Securities, the principal amounts at maturity) of the particular
         Securities to be redeemed,

                  (5) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and that
         interest thereon will cease to accrue on and after said date,

                  (6) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

                  (7) that in the case that a Security is only redeemed in part,
         the Issuer shall execute and the Trustee shall authenticate and deliver
         to the Holder of such Security without service charge, a new Security
         or Securities in an aggregate amount equal to the unredeemed portion of
         the Security.

                  Notice of redemption of Securities to be redeemed at the
election of the Issuer shall be given by the Issuer or, at the Issuer's request,
by the Trustee in the name and at the expense of the Issuer. If so requested by
the Issuer, the Trustee shall mail any such notice not later than the date
specified for mailing by the Issuer, which shall not be sooner than 5 days after
receipt by the Trustee of such request (unless a shorter period shall be
satisfactory to the Trustee).

                  SECTION 11.06. Deposit of Redemption Price. Prior to any
Redemption Date, the Issuer shall deposit with


                                      -121-

the Trustee or with a Paying Agent (or, if the Issuer is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 10.03) an
amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

                  SECTION 11.07. Securities Payable on Redemption Date. Notice
of redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Issuer shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Issuer at the
Redemption Price, together with accrued interest to but excluding the Redemption
Date; provided, however, that installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the bearer of such
Security, in the case of a Global Security in bearer form, and, in the case of a
Definitive Security, to Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.07.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium, if any)
shall, until paid, bear interest from the Redemption Date at the rate provided
by the Security.

                  SECTION 11.08. Securities Redeemed in Part. Any Security which
is to be redeemed only in part shall be surrendered at an office or agency of
the Issuer designated for that purpose pursuant to Section 10.02 (with, if the
Issuer or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Issuer
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of like
tenor, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

                  (b) 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 Guarantors, the Issuer or any of their
         Subsidiaries is a party or by which the Guarantors, the Issuer or any

         a ruling based on relevant law and practice at the time directed to the
         Trustee from the Inland Revenue or other relevant tax authority to the

         U.K. income tax or other tax purposes as a result of the Issuer's
         exercise of its option under this Section 12.02, disregarding income
         tax on any amounts that would have been received but for such exercise
         of its option under this Section 12.02, and will be subject to U.K.
         income tax on the same amount and in the same manner and at the same
         time as would have been the case if such option had not been exercised
         or (ii) an Opinion of Counsel to the same effect as the ruling

                  (e) the Issuer shall have delivered to the Trustee (i) either
         (A) a ruling directed to the Trustee received from the Internal Revenue
         Service to the effect that the Holders will not recognize additional
         income, gain or loss for U.S. federal income tax purposes as a result
         of the Issuer's exercise of its option under this Section 12.02 and
         will be subject to U.S. 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 option had not been exercised or (B) an Opinion of Counsel to the
         same effect as the ruling described in clause (A) above accompanied by
         a ruling to that effect published by the Internal Revenue Service,
         unless there has been a change in the relevant U.S. federal income tax
         law since the date of this Indenture and (ii) an Opinion of Counsel to
         the effect that (A) the creation of the defeasance trust does not
         violate the Investment Company Act of 1950 and (B) after the passage of
         123 days following the deposit


                                      -125-

         (except, with respect to any trust funds for the account of any Holder
         who may be deemed to be "connected" with the Issuer for purposes of the
         Insolvency Act 1986 after two years following the deposit), the trust
         funds will not be subject to the effect of Section 557 of the United
         States Bankruptcy Code or Section 15 of the New York Debtor and
         Creditor Law and either (I) the trust funds will no longer remain the
         property of the Issuer (and therefore will not be subject to the effect
         of any applicable bankruptcy, insolvency, reorganization or similar
         laws affecting creditors' rights generally) or (II) if a court were to
         rule under any such law in any case or proceeding that the trust funds
         remained property of the Issuer (1) assuming such trust funds remained
         in the possession of the Trustee prior to such court ruling to the
         extent not paid to the Holders, the Trustee will hold, for the benefit
         of the Holders, a valid and perfected security interest in such trust
         funds that is not avoidable in bankruptcy or otherwise and (2) no
         property, rights in property or other interests granted to the Trustee
         or the Holders in exchange for, or with respect to, such trust funds
         will be subject to any prior rights of holders of other Debt of the
         Issuer or any of its Securities;

                  (f) if at such time the Securities are listed on a national
         securities exchange, the Issuer shall have delivered to the Trustee an
         Opinion of Counsel to the effect that the Securities will not be
         delisted as a result of the Issuer's exercise of its opinion under this
         Section 12.02; and

                  (g) the Issuer 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 12.02 have been complied with.

                  Notwithstanding the foregoing, prior to the end of the post
deposit period referred to in clause (e)(ii)(B) of this Section 12.02, none of
the Issuer's obligations under this Indenture shall be discharged. Subsequent to
the end of such period with respect to this Section 12.02, the Issuer's
obligations in Sections 3.03, 3.05, 3.05, 3.06, 3.07, 10.01, 10.09, 6.07, 6.10,
6.11, 12.05, 12.05 and 12.06 shall survive until the Securities mature or are
redeemed. Thereafter, only the Issuer's obligations in Sections 6.07, 12.05 and
12.06 shall survive. If and when a ruling from the Internal Revenue Service or
an Opinion of Counsel referred to in clause (e)(i) of this Section 12.02 may be
provided specifically without regard to, and not in reliance


                                      -126-

upon, the continuance of the Issuer's obligations under Section 10.01, then the
Issuer's obligations under such sentence 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 12.02.

                  After any such irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of the Issuer's obligations under the
Securities, any Subsidiary Guarantee, if any, and this Indenture except for
those surviving obligations in the immediately preceding paragraph.

                  SECTION 12.03. Defeasance of Certain Obligations. The Issuer
and the Guarantors may omit to comply with any term, provision or condition set
forth in clauses (3) and (5) of Section 8.01 and Sections 10.05 through 10.18
(except for Section 10.09 and any covenant otherwise required by the TIA), and
clause (d) of Section 5.01 with respect to clauses (3) and (5) of Section 8.01,
clauses (d) and (e) of Section 5.01 with respect to Sections 10.05 through
10.18, except as aforesaid, and clauses (c), (f) and (g) of Section 5.01 shall
be deemed not to be Events of Default, in each case with respect to the
Outstanding Securities if:

                  (a) with reference to this Section 12.03, the Issuer has
         irrevocably deposited or caused to be irrevocably deposited with the
         Trustee and conveyed all right, title and interest to the Trustee for
         the benefit of the Holders, under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee as trust
         funds in trust, specifically pledged to the Trustee for the benefit of
         the Holders as security for payment of the principal of, premium, if
         any, and interest, if any, on the Securities, and dedicated solely to,
         the benefit of the Holders, in and to (i) money in an amount, (ii) U.S.
         Government Obligations that, through the payment of interest and
         principal in respect thereof in accordance with their terms, will
         provide, not later than one day before the due date of any payment
         referred to in this clause (a), money in an amount or (iii) a
         combination thereof in an amount sufficient, in the opinion of a
         nationally recognized firm of independent public accountants expressed
         in a written certification thereof delivered to the Trustee, to pay and
         discharge, without consideration of the reinvestment of such interest
         and after payment of all federal, state and local taxes or other
         charges and assessments in respect thereof payable by the Trustee, the
         principal of, premium, if any, and interest on the Outstanding
         Securities on the Stated Maturity or upon earlier


                                      -127-
<PAGE>


         redemption of such principal or interest; provided that the Trustee
         shall have been irrevocably instructed to apply such money or the
         proceeds of such U.S. Government Obligations to the payment of such
         principal, premium, if any, and interest with respect to the Securities
         and to give any related notice of redemption;

                  (b) 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 Parent Guarantor, the Issuer or any of their
         Subsidiaries is a party or by which the Parent Guarantor, the Issuer or
         any of their Subsidiaries is bound;

                  (c) immediately after giving effect to such deposit or a pro
         forma basis, no Default or Event of Default, or event that after the
         giving of notice or lapse of time or both would become a Default or
         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 day
         of such deposit;

                  (d) the Issuer has delivered to the Trustee an Opinion of
         Counsel to the effect that (i) the creation of the defeasance trust
         does not violate the Investment Company Act of 1950, (ii) the Holders
         will not recognize income, gain or loss for U.S. federal income tax
         purposes as a result of such deposit and the defeasance of the

         and will be subject to U.S. 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 (iii) after the
         passage of 123 days following the deposit (except with respect to any
         trust funds for the account of any Holder who may be deemed to be
         "connected" with the Issuer for purposes of the Insolvency Act 1986
         after two years following the deposit), the trust funds will not be
         subject to the effect of Section 557 of the United States Bankruptcy
         Code or Section 15 of the New York Debtor and Creditor Law, and either
         (A) the trust funds will no longer remain the property of the Issuer
         (and therefore will not be subject to the effect of any applicable
         bankruptcy, insolvency, reorganization or similar laws affecting
         creditor's rights generally) or (B) if a court were to rule under any
         such law in any case or proceeding that the trust funds remained
         property of the Issuer (1) assuming such trust funds remained in the
         possession of the Trustee prior to such court ruling to the extent not
         paid to the Holders, the


                                      -128-
<PAGE>


         Trustee will hold, for the benefit of the Holders, a valid and
         perfected security interest in such trust funds that is not avoidable
         in bankruptcy or otherwise and (2) no property, rights in property or
         other interests granted to the Trustee or the Holders in exchange for,
         or with respect to, such trust funds will be subject to any prior
         rights or holders of other Indebtedness of the Issuer or any of its
         Securities;

                  (e) if at such time the Securities are listed on a national
         securities exchange, the Issuer has delivered to the Trustee an Opinion
         of Counsel to the effect that the Securities will not be delisted as a
         result of the Issuer's exercise of its option under Section 12.03; and

                  (f) the Issuer 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 defeasance
         contemplated by this Section 12.03 have been complied with.

                  SECTION 12.05. Application of Trust Money. Subject to Section
12.06, the Trustee or Paying Agent shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to Section 12.01, 12.02 or 12.03, as the
case may be, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with the Securities and this Indenture to
the payment of principal of, premium, if any, and interest on the Securities;
but such money need not be segregated from other funds except to the extent
required by law.

                  SECTION 12.05. Repayment to Issuer. Subject to Sections 6.07,
12.01, 12.02 and 12.03, the Trustee and the Paying Agent shall promptly pay to
the Issuer upon request set forth in an Officers' Certificate any excess money
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 Issuer
any money held by them for the payment of principal, premium, if any, or
interest that remains unclaimed in accordance with Section 10.02.

                  SECTION 12.06. Reinstatement. If the Trustee or Paying Agent
is unable to apply any money or U.S. Government Obligations in accordance with
Section 12.01, 12.02 or 12.03, 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
obligations of the Issuer and the Guarantors under this Indenture, the
Securities Guarantee, and the Securities shall be revived and


                                      -129-
<PAGE>


reinstated as though no deposit had occurred pursuant to Section 12.01, 12.02 or
12.03, as the case may be, until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S. Government Obligations in accordance
with Section 12.01, 12.02 or 12.03, as the case may be; provided that, if the
Issuer has made any payment of principal of, premium, if any, or interest on any
Securities because of the reinstatement of its obligations, the Issuer shall be
subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent.

                  SECTION 12.07. Insiders. With respect to the determination of
the Persons constituting beneficial owners of Securities and whether any such
Person is "connected" with the Issuer for purposes of Sections 12.02(e)(ii)(B)
and 12.03(d)(iii), the Trustee may rely on an Officers' Certificate.

                  an affiliate of the Issuer or any such distributor or a person
                  acting on behalf of any of the foregoing;

                           (B)  the offer of the Specified Securities
                  was not made to a person in the United States;

                           (C)  either:

                                    (i) at the time the buy order was
                           originated, the Transferee was outside the United
                           States or the Owner and any person acting on its
                           behalf reasonably believed that the Transferee was
                           outside the United States, or

                                    (ii) the transaction is being executed in,
                           on or through the facilities of the Eurobond market,

                           Dealers, or another designated offshore securities
                           market and neither the Owner nor any person acting on
                           its behalf knows that the transaction has been
                           prearranged with a buyer in the United States;

                           (D)      no directed selling efforts have been
                  made in the United States by or on behalf of the
                  Owner or any affiliate thereof;

                  respect of the Specified Securities, and the transfer is to
                  occur during the Restricted Period, then the requirements of

                  of at least one year (computed in accordance with paragraph

                  SECTION 1.02. Compliance Certificates and Opinions. Upon any
application or request by the Issuer to the Trustee to take any action under any
provision of this Indenture, the Issuer and Guarantors shall furnish to the

Indenture Act and under this Indenture. Each such certificate or opinion shall
be given in the form of an Officers' Certificate, if to be given by an officer
of the Issuer or the Guarantors, or an Opinion of Counsel, if to be given by
counsel, and shall comply with the requirements of the Trust Indenture Act and

         individual, such condition or covenant has been complied with.


                                      -31-

<PAGE>



                  SECTION 1.03. Form of Documents Delivered to Trustee. In any
case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

                  Any certificate of an officer of the Issuer or either
Guarantor may be based, insofar as it relates to legal matters, upon an opinion
of counsel submitted therewith, unless such officer knows, or in the exercise of
reasonable care should know, that the opinion with respect to the matters upon
which his certificate is based is erroneous. Any opinion of counsel may be
based, insofar as it relates to factual matters, upon a certificate of an
officer or officers of the Issuer or either Guarantor submitted therewith
stating the information on which counsel is relying, unless such counsel knows,
or in the exercise of reasonable care should know, that the certificate with
respect to such matters is erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

                  SECTION 1.05. Acts of Holders; Record Dates. Any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such Holders 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 and, where it is
hereby expressly required, to the Issuer or the Guarantors. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 6.01) conclusive in favor of the Trustee


                                      -32-

<PAGE>



and the Issuer and Parent Guarantor, if made in the manner provided in this
Section.

                  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

                  The ownership of Securities shall be proved by the Security
Register.

                  Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, the
Issuer or the Parent Guarantor in reliance thereon, whether or not notation of
such action is made upon such Security.

                  The Issuer may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities; provided that the Issuer may not set a record date for,
and the provisions of this paragraph shall not apply with respect to, the giving
or making of any notice, declaration, request or direction referred to in the
next paragraph. If not set by the Issuer prior to the first solicitation of a
Holder made by any Person in respect of any such matter referred to in the
foregoing sentence, the record date for any such matter shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 7.01) prior to such first solicitation. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take
the relevant action,


                                      -33-

<PAGE>



whether or not such Holders remain Holders after such record date; provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount at
maturity of Outstanding Securities on such record date. Nothing in this
paragraph shall be construed to prevent the Issuer from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount at maturity of Outstanding Securities on the
date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Issuer, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Trustee in writing and to each Holder of Securities in the
manner set forth in Section 1.06.

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.02, (iii) any request to institute
proceedings referred to in Section 5.07(2) or (iv) any direction referred to in
Section 5.12. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount at maturity of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Trustee from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be canceled and of no effect), and nothing in this paragraph shall
be construed to render ineffective any action taken by Holders of the requisite
principal amount at maturity of Outstanding Securities on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Trustee, at the Issuer's expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration


                                      -35-

<PAGE>



Date to be given to the Issuer in writing and to each Holder of Securities in
the manner set forth in Section 1.06.

                  With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities in the manner set forth in Section
1.06, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

                  Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

                  SECTION 1.05. Notices, Etc., to Trustee, Issuer and
Guarantors. Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Issuer or the either
         Guarantor shall be sufficient for every purpose hereunder if in writing
         and delivered in person or by first class mail, commercial courier
         service or telecopies communication to a Responsible Officer of the
         Trustee at its Corporate Trust Office, Attention: Corporate Trust
         Administration, or as may otherwise be expressly provided in any
         solicitation of any Act of the Holders, or

                  (2) the Issuer or either Guarantor by the Trustee or by any
         Holder shall be sufficient for every purpose hereunder (unless
         otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Issuer or either Guarantor as
         applicable,


                                      -35-

<PAGE>



         addressed to it, if prior to receipt by the Trustee of written notice
         pursuant to this Section 1.05 of a change of address, at the address of
         its principal office specified in the first paragraph of this
         instrument, or, if after receipt by the Trustee of written notice
         pursuant to this Section 1.05 of a change of address, at such other
         address as may be previously furnished in writing to the Trustee by the
         Issuer or either Guarantor, as applicable.

                  SECTION 1.06. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date
(if any), and not earlier than the earliest date (if any), prescribed for the
giving of such notice. 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,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. 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 1.07. Application of Trust Indenture Act. The Trust
Indenture Act shall apply as a matter of contract to this Indenture for purposes
of interpretation, construction and defining the rights and obligations
hereunder. If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply


                                      -36-

<PAGE>



to this Indenture as so modified or to be excluded, as the case may be.

                  SECTION 1.08. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 1.09. Successors and Assigns. All covenants and
agreements in this Indenture by the Issuer and the Guarantors shall bind their
respective successors and assigns, whether so expressed or not.

                  SECTION 1.10. Separability Clause. In case any provision in
this Indenture or in the Securities shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

                  SECTION 1.11. Benefits of Indenture. Nothing in this Indenture
or in the Securities, express or implied, shall give to any Person, other than
the parties hereto and their successors hereunder and the Holders of Securities,
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

                  SECTION 1.12. Governing Law. This Indenture, the Securities
and the Securities Guarantee shall be governed by and construed in accordance
with the laws of the State of New York.

                  SECTION 1.13. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, Purchase Date or Stated Maturity of any Security
shall not be a Business Day, then (notwithstanding any other provision of this
Indenture or of the Securities) payment of interest or principal (and premium,
if any) 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, Redemption Date, Purchase Date or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date, Purchase Date or Stated Maturity, as the case may be.

                  SECTION 1.15. Agent for Service; Submission to Jurisdiction;
Waiver of Immunities. By the execution and delivery of this Indenture, each of
the Issuer, the Parent Guarantor and the Subsidiary Guarantor (i) represents
that it has designated and appointed RSL Communications N. America, Inc.
("RSLNA"), as its authorized agent upon


                                      -37-

<PAGE>



which process may be served in any suit, action or proceeding arising out of or
relating to the Securities, the Securities Guarantee or this Indenture that may
be instituted in any Federal or state court in the State of New York, Borough of
Manhattan, or brought under Federal or state securities laws or brought by the
Trustee (whether in its individual capacity or in its capacity as Trustee
hereunder), and that RSLNA has accepted such designation, (ii) submits to the
non-exclusive jurisdiction of any such court in any such suit, action or
proceeding, (iii) agrees that service of process upon RSLNA and written notice
of said service to the Issuer or the Parent Guarantor, as applicable, (mailed or
delivered to its President at its principal office as specified in Section 1.05)
shall be deemed in every respect effective service of process upon it in any
such suit or proceeding, and (iv) agrees to take any and all action, including
the execution and filing of any and all such documents and instruments as may be
necessary to continue such designation and appointment of RSLNA in full force
and effect so long as any of the Securities shall be Outstanding.

                  To the extent that the Issuer or either Guarantor has or
hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, each of the Issuer, Parent Guarantor and the Subsidiary
Guarantor hereby irrevocably waives such immunity in respect of its obligations
under this Indenture, the Securities Guarantee and the Securities, to the extent
permitted by law.

                  SECTION 1.15. Currency Indemnity. The Euro is the sole
currency of account and payment for all sums payable by the Issuer or the
Guarantors under or in connection with the Securities, including damages. Any
amount received or recovered in a currency other than the Euro (whether as a
result of, or the enforcement of, a judgment or order of a court of any
jurisdiction, in the winding-up or dissolution of the Issuer or the Guarantors
or otherwise) by any Holder of a Security in respect of any sum expressed to be
due to it from the Issuer or the Guarantors shall only constitute a discharge to
the Issuer or the Guarantors, as applicable, to the extent of the Euro amount
which the recipient is able to purchase with the amount so received or recovered
in that other currency on the date of that receipt or recovery (or, if it is not
practicable to make that purchase on that date, on the first date on which it is
practicable to do so). If the Euro amount received is


                                      -38-

<PAGE>



less than the Euro amount expressed to be due to the recipient under any
Security, the Issuer or the Guarantors, as applicable, shall indemnify it
against any loss sustained by it as a result. In any event, the Issuer or
Guarantors shall indemnify the recipient against the cost of making any such
purchase. For the purposes of this Section, it will be sufficient for the Holder
of a Security to certify in a satisfactory manner (indicating the sources of
information used) that it would have suffered a loss had an actual purchase of
the Euro been made with the amount so received in that other currency on the
date of receipt or recovery (or, if a purchase of the Euro on such date had not
been practicable, on the first date on which it would have been practicable, it
being required that the need for a change of date be certified in the manner
mentioned above). These indemnities constitute a separate and independent
obligation from the Issuer's and the Guarantors' other obligations, shall give
rise to a separate and independent cause of action, shall apply irrespective of
any indulgence granted by any Holder of a Security and shall continue in full
force and effect despite any other judgment, order, claim or proof for a
liquidated amount in respect of any sum due under any Security.

their Participants shall have any rights either under this Indenture or under
any Global Security with respect to such Global Security held on their behalf by
the Book-Entry Depositary, and the Book-Entry Depositary may be treated by the
Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute
owner of such Global Security for the purpose of receiving payment of or on
account of the principal of (premium, if any) and, subject to the provisions of
this Indenture, interest on the Global Security and for all other purposes.

Trustee or any agent of the Issuer or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Book-Entry
Depositary or impair, as between the Book-Entry Depositary, the Common
Depositary, Euroclear and Clearstream, and their Participants, the operation of
customary practices of Euroclear and Clearstream governing the exercise of the
rights of an owner of a beneficial interest in any Global Security.

                  SECTION 2.03. Form of Reverse of Security. This Security is
one of a duly authorized issue of Securities of the Issuer designated as its
12 7/8% Senior Notes due 2010 (the "Securities") issued under an Indenture,
dated as of February 22, 2000 (herein called the "Indenture"), between the
Issuer, RSL Communications, Ltd., as a Parent Guarantor (the "Parent Guarantor",
which term includes any successor Person under the Indenture) RSL COM U.S.A.,
Inc., as a guarantor (the "Subsidiary Guarantor", which term includes any
successor Person under the Indenture, and together with the Parent Guarantor,
the "Guarantors") and The Chase Manhattan Bank, as trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture).
Reference is hereby made to the Indenture and all indentures supplemental
thereto for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Issuer, the Guarantors, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

                  The Securities are subject to redemption upon not less than 30
nor more than 60 days' notice by mail to each Holder of Securities to be
redeemed at such Holder's address appearing in the Security Register, in amounts
of (U)1,000 or an integral multiple of (U)1,000, at any time on or after March
1, 2005 and prior to maturity, as a whole or in part, at the election of the
Issuer, at the following Redemption Prices (expressed as percentages of the
principal amount) plus accrued interest to but excluding the Redemption Date
(subject to the right of Holders [If this Security is not a Global Security
issued in bearer form, insert: on the relevant Regular Record Date] to receive
interest due on an Interest Payment Date that is on or prior to the Redemption
Date), if redeemed during the 12-month period beginning March 1, of each of the
years indicated below:

                   Year                           Price
                   ----                           -----
                   2005                          106.538%
                   2006                          105.292%
                   2007                          102.156%
                 2008 and
                thereafter                       100.000%

and thereafter at a Redemption Price equal to 100% of the principal amount,
together in the case of any such


                                      -56-

<PAGE>



redemption with accrued interest to but excluding the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities [If this Security is not a Global Security issued in
bearer form, insert:, of record at the close of business on the relevant Record
Dates referred to on the face hereof,] all as provided in the Indenture.

                  In addition, at any time prior to March 1, 2003, in the event
that the Guarantors receive net cash proceeds from the public or private sale of
its Common Stock (other than Disqualified Stock), the Issuer (to the extent it
receives such proceeds and has not used such proceeds, directly or indirectly,
to redeem or repurchase other securities pursuant to optional redemption
provisions) may, at its option, apply an amount equal to any such net cash
proceeds or any portion thereof to redeem, from time to time, Securities in a
principal amount of up to an aggregate amount equal to 33 1/3% of the aggregate
principal amount at maturity of the Securities; provided, however, that
Securities in an amount equal to at least 66 2/3% of the aggregate principal
amount at maturity of the Securities remain Outstanding after each redemption.
Each redemption must occur on a Redemption Date within 180 days of the related
sale and upon not less than 30 nor more than 60 days' notice by mail to each
Holder of Securities to be redeemed at such Holder's address appearing in the
Security Register, in amounts of (U)1,000 or an integral multiple of (U)1,000 at
a Redemption Price of 112.875% of the principal amount of the Securities plus
accrued interest to but excluding the Redemption Date.

                  Furthermore, in the event that (i) the Guarantors or the
Issuer has become or would become obligated to pay any Additional Amounts as a
result of (x) changes affecting withholding tax laws or (y) a Listing Failure,
provided that the Issuer has used reasonable best efforts to list and maintain a
listing of the Securities on a "recognized stock exchange" (within the meaning
of Section 851 of the U.K. Income and Corporation Taxes Act 1988) (as provided
for in Section 10.09), and (ii) the Guarantors and the Issuer are unable to
avoid the requirement to pay such Additional Amounts by taking reasonable
measures available to them (including, without limitation, the Guarantors making
payments directly to holders under the Securities Guarantee, unless such payment
is likely to result in adverse consequences to the Issuer or the Guarantors),
then the Issuer may redeem all, but not less than all, of the Securities at any
time at 100% of the principal amount


                                      -57-

<PAGE>



thereof on the Redemption Date, together with accrued interest thereon, if any,
to but excluding the Redemption Date. Prior to the publication of the notice of
redemption in accordance with the foregoing, the Issuer shall deliver to the
Trustee an officer's certificate stating that the Issuer is entitled to effect
such redemption based on a written opinion of independent tax counsel or
accounting firm reasonably satisfactory to the Trustee.

                  The Securities do not have the benefit of any sinking fund
obligations.

                  The Indenture provides that, subject to certain conditions, if
(i) a Change of Control occurs or (ii) certain Net Available Proceeds are
available to the Issuer as a result of any Asset Disposition, the Issuer shall
be required to make an Offer to Purchase for all or a specified portion of the
Securities.

                  [If not a Global Security: In the event of redemption or
purchase pursuant to an Offer to Purchase of this Security in part only, a new
Security or Securities of like tenor for the unredeemed or unpurchased portion
hereof will be issued in the name of the Holder hereof upon the cancelation
hereof.]

                  [If a Global Security insert: In the event of a deposit or
withdrawal of a beneficial interest in this Security (including upon an
exchange, transfer, redemption or repurchase of this Security in part only)
effected in accordance with the Applicable Procedures, the Security Registrar,
upon receipt of notice of such event from Euroclear or Clearstream, shall make
an adjustment on its records to reflect an increase or decrease of the
Outstanding principal amount at maturity of this Security resulting from such
deposit or withdrawal, as the case may be, and shall instruct the Book-Entry
Depositary to make a similar notation in its book-entry system to the
corresponding Depositary Interest.]

                  If an Event of Default shall occur and be continuing, the
principal of all the Securities may be declared due and payable in the manner
and with the effect provided in the Indenture.

                  The Indenture contains provisions for defeasance at any time
of (i) the entire indebtedness of this Security, or (ii) certain restrictive
covenants and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

                  Unless the context otherwise requires, the Original Securities
and the Exchange Securities shall constitute one series for all purposes under
the Indenture, including without limitation, amendments, waivers,
redemptions and Offers to Purchase.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Issuer, the Guarantors and the rights of the Holders of the
Securities under the Indenture at any time by the Issuer, the Guarantors and the
Trustee with the consent of the Holders of a majority in aggregate principal
amount at maturity of the Securities at the time Outstanding. The Indenture also
contains provisions permitting the Holders of specified percentages in aggregate
principal amount at maturity of the Securities at the time Outstanding, on
behalf of the Holders of all the Securities, to waive compliance by the Issuer
or the Guarantors with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent or waiver
by the Holder of this Security shall be conclusive and binding upon such Holder
and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest on this Security at the times, place and rate, and in the coin
or currency, herein prescribed.

                  [If this Security is not a Global Security issued in bearer
form, then insert: As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Issuer in the Borough of Manhattan, the
City of New York, New York, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Issuer and the Security
Registrar duly executed by the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securities, of authorized denominations
and like tenor and for the same aggregate principal amount at maturity, will be
issued to the designated transferee or transferees.]

coupons in denominations of (U)1,000 and any integral multiple thereof.
Definitive Securities shall be issuable in registered form without interest
coupons in denominations of (U)1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities are exchangeable for a like tenor and aggregate principal amount at
maturity of Securities of a different authorized denomination, as requested by
the Holder surrendering the same.

then insert: The bearer of this Security shall be treated as the owner of this
Security for all purposes.]

                  No service charge shall be made for any such registration of

cover any tax or other governmental charge payable in connection therewith.

                                 The Securities

                  SECTION 3.01. Title and Terms. The aggregate principal amount
of Securities which may be authenticated and delivered under this Indenture is
unlimited; provided that unless the Issuer authorizes the execution and delivery
of Additional Securities pursuant to Section 3.12, the aggregate principal
amount of Securities shall be limited to (U)100,000,000, except for Securities
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, other Securities pursuant to Section 3.05, 3.05, 3.06, 9.06
or 11.08 or in connection with an Offer to Purchase pursuant to Section 10.13 or
10.17 (all Securities referred to in this exception being deemed "Substitute
Securities"). The Issuer may issue Exchange Securities from time to time
pursuant to an Exchange Offer or otherwise, in each case pursuant to a Board
Resolution, subject to Section 3.03, included in an Officers' Certificate
delivered to the Trustee, in authorized denominations in exchange for a like
principal amount at maturity of Original Securities. Upon any such exchange the
Original Securities shall be canceled in accordance with Section 3.09 and shall
no longer be deemed Outstanding for any purpose. In no event shall the aggregate
principal amount at maturity of Original Securities and Exchange Securities
Outstanding exceed (U)100,000,000.

                  The Securities shall be known and designated as the "12 7/8%
Senior Notes due 2010" of the Issuer. The Stated Maturity of the Securities
shall be March 1, 2010. The Securities shall bear cash interest at the rate of
12.875% per annum on the principal amount at maturity of the Securities, from
February 22, 2000 or from the most recent Interest Payment Date thereafter to
which interest has been paid or duly provided for, as the case may be, payable
semi-annually on March 1 and September 1, commencing September 1, 2000 until the
principal thereof is paid or made available for payment; provided, however, with
respect to Original Securities, if there has been a Registration Default, a
Step-Up will occur and the Original Securities will from then bear Special
Interest to but excluding the Step-Down Date. Accrued Special Interest, if any,
shall be paid in cash in arrears semi-annually on March 1 and September 1 in
each year, and the amount of accrued Special Interest shall be determined on the
basis of the number of days actually elapsed.

                  With respect to Global Securities, the Issuer will pay
interest, if any, on such Securities to the bearers of such Securities. Holders
of such Global Securities must surrender such Securities to the Trustee to

on the Securities shall be payable at the corporate trust office of the Trustee
in the Borough of Manhattan, the City of New York, New York, maintained for such
purpose and at any other office or agency maintained by the Issuer for such
purpose; provided, however, that at the option of the Issuer payment of interest
may be made by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register.

                  The Securities shall be subject to repurchase by the Issuer
pursuant to an Offer to Purchase as provided in Sections 10.13 and 10.17 of the
Indenture.

                  The Securities shall be redeemable as provided in Article
Eleven.

                  The Securities shall not have the benefit of any sinking fund
obligations.

                  The Securities shall be subject to defeasance at the option of
the Issuer as provided in Article Twelve.

                  The Securities are guaranteed by the Guarantors as set forth
in Article IV of this Indenture.

                  A copy of an appropriate record of such action shall be
certified by the Secretary or any Assistant Secretary of the Issuer and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate or the trust indenture supplemental hereto setting forth the terms
of such Securities.

                  Unless the context otherwise requires, the Original Securities
and the Exchange Securities shall constitute one series for all purposes under
the Indenture, including without limitation, amendments, waivers,
redemptions and Offers to Purchase.

                  SECTION 3.02. Denominations. The Global Securities shall be
issuable in bearer form without coupons and only in denominations of (U)1,000
and any integral multiple of (U)1,000 in excess thereof. Definitive Registered
Securities shall be issuable in registered form without interest coupons in
denominations of (U)1,000 and any integral multiple thereof.

                  SECTION 3.03. Execution, Authentication, Delivery and Dating.
The Securities shall be executed on behalf of the Issuer by its Chairman of the
Board, its Vice Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Issuer shall bind
the Issuer, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Issuer may deliver Securities executed by the
Issuer to the Trustee for authentication, together with a Issuer Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Issuer Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise.

                  At any time and from time to time after the execution and
delivery of this Indenture and after the effectiveness of a Registration
Statement under the Securities Act with respect thereto, the Issuer may deliver
Exchange Securities executed by the Issuer to the Trustee for authentication,
together with an Issuer Order for the authentication and delivery of such
Exchange Securities and a like principal amount at maturity of Original
Securities for cancelation in accordance with Section 3.09 of this Indenture,
and the Trustee in accordance with the Issuer Order shall authenticate and
deliver such Securities. In authenticating such Exchange Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to
Section 6.01) shall be fully protected in relying upon, an Opinion of Counsel
stating,

                  (a) that such Exchange Securities have been duly and validly
         issued in accordance with the terms of the Indenture, and are entitled
         to all the rights and benefits set forth herein; and

                  (b) that the issuance of the Exchange Securities in exchange
         for the Original Securities has been


                                      -55-

<PAGE>



         effected in compliance with the Securities Act of 1933, as amended.

                  Each Security shall be dated the date of its authentication.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

                  SECTION 3.05. Temporary Securities. Pending the preparation of
definitive Securities, the Issuer may execute, and upon Issuer Order the Trustee
shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

                  If temporary Securities are issued, the Issuer will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Issuer designated pursuant to Section
10.02, without charge to the Holder. Upon surrender for cancelation of any one
or more temporary Securities, the Issuer shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like tenor and principal amount
at maturity of definitive Securities of authorized denominations. Until so
exchanged, the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities.

                  SECTION 3.05. Registration, Registration of Transfer and
Exchange. (a) The Issuer shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.02 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Issuer shall provide for the


                                      -55-

<PAGE>



registration of Definitive Securities and of transfers of such Securities. The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
such Securities and transfers of such Securities as herein provided. Such
Security Register shall distinguish between Original Securities and Exchange
Securities.

                  Subject to the other provisions of this Indenture regarding
restrictions on transfer, upon surrender for registration of transfer of any
Definitive Security at an office or agency of the Issuer designated pursuant to
Section 10.02 for such purpose in accordance with the terms hereof, the Issuer
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like tenor and aggregate principal amount at
maturity and bearing such restrictive legends as may be required by this
Indenture.

                  At the option of the Holder, and subject to the other
provisions of this Section 3.05, Securities may be exchanged for other
Securities of any authorized denominations and of a like tenor and aggregate
principal amount at maturity, upon surrender of such Securities to be exchanged
at such office or agency. Whenever any Securities are so surrendered for
exchange, the Issuer shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Issuer, evidencing
the same debt, and (subject to the provisions in the Original Securities
regarding the payment of Special Interest) entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Issuer or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Security Registrar 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 Securities, but the Issuer may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in


                                      -56-

<PAGE>



connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.05, 3.05(d), 9.06 or 11.08 or in accordance
with any Offer to Purchase pursuant to Section 10.13 or 10.17 not involving any
transfer.

                  The Issuer shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 11.05 and ending at the close
of business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

                  (b) Certain Transfers and Exchanges. Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 3.05(b) shall be made only in accordance with this Section
3.05(b) or, if necessary, in accordance with such other procedures as the Issuer
shall develop which shall comply with applicable securities laws.

                         (i) Restricted Global Security to Regulation S Global
         Security. If the owner of a beneficial interest in the Restricted
         Global Security wishes at any time to transfer such interest to a
         Person who wishes to acquire the same in the form of a beneficial
         interest in the Regulation S Global Security, such transfer may be
         effected only in accordance with the provisions of this Clause (b)(i)
         and subject to the Applicable Procedures. Upon receipt by the Trustee,
         as Security Registrar, of (A) an order given by Euroclear or
         Clearstream or an authorized representative of Euroclear or Clearstream
         directing that a beneficial interest in the Regulation S Global
         Security in a specified principal amount at maturity be credited to a
         specified Participant's account and that a beneficial interest in the
         Restricted Global Security in an equal principal amount at maturity be
         debited from another specified Participant's account and (B) a
         Regulation S Certificate, satisfactory to the Trustee and duly executed
         by the owner of such beneficial interest in the Restricted Global
         Security or his attorney duly authorized in writing, then the Trustee,
         as Security Registrar, shall reduce or cause to be reduced the
         principal amount at maturity of the Restricted Global Security and
         increase the principal amount at maturity


                                      -57-

<PAGE>



         of the Regulation S Global Security by such specified principal amount
         at maturity as provided in Section 3.05(e).

                        (ii) Regulation S Global Security to Restricted Global
         Security. If the owner of a beneficial interest in the Regulation S
         Global Security wishes at any time to transfer such interest to a
         Person who wishes to acquire the same in the form of a beneficial
         interest in the Restricted Global Security, such transfer may be
         effected only in accordance with this Clause (b)(ii) and subject to the
         Applicable Procedures. Upon receipt by the Trustee, as Security
         Registrar, of (A) an order given by Euroclear or Clearstream or an
         authorized representative of Euroclear or Clearstream directing that a
         beneficial interest in the Restricted Global Security in a specified
         principal amount at maturity be credited to a specified Participant's
         account and that a beneficial interest in the Regulation S Global
         Security in an equal principal amount at maturity be debited from
         another specified Participant's account and (B) if such transfer is to
         occur during the Restricted Period, a Restricted Securities
         Certificate, satisfactory to the Trustee and duly executed by the owner
         of such beneficial interest in the Regulation S Global Security or his
         attorney duly authorized in writing, then the Trustee, as Security
         Registrar, shall reduce or cause to be reduced the principal amount at
         maturity of the Regulation S Global Security and increase the principal
         amount at maturity of the Restricted Global Security by such specified
         principal amount at maturity as provided in Section 3.05(e).

                       (iii) Definitive Security to Definitive Security. A
         Security that is a Definitive Security may be transferred, in whole or
         in part, to a Person who takes delivery in the form of another Security
         that is a Definitive Security as provided in Section 3.05(a), provided
         that, if the Security to be transferred in whole or in part is a
         Restricted Security, or is a Regulation S Security and the transfer is
         to occur during the Restricted Period, then the Trustee shall have
         received (A) a Restricted Securities Certificate, satisfactory to the
         Trustee and duly executed by the transferor Holder or his attorney duly
         authorized in writing, in which case the transferee Holder shall take
         delivery in the form of a Restricted Security, or (B) a Regulation S
         Certificate, satisfactory to the Trustee and duly executed by the
         transferor Holder or his attorney duly authorized in writing, in which
         case the


                                      -58-

<PAGE>



         transferee Holder shall take delivery in the form of a Regulation S
         Security (subject in every case to Section 3.05(c)).

                        (iv) Exchanges between Global Security and Definitive
         Security. A beneficial interest in a Global Security may be exchanged
         for a Security that is a Definitive Security as provided in Section
         3.05(d), provided that, if such interest is a beneficial interest in
         the Restricted Global Security, or if such interest is a beneficial
         interest in the Regulation S Global Security and such exchange is to
         occur during the Restricted Period, then such interest shall be
         exchanged for a Restricted Security or a Regulation S Security, as the
         case may be (subject in each case to Section 3.05(c)).

                  (c) Securities Act Legends. Rule 155A Securities and their
Successor Securities shall bear a Restricted Securities Legend, and the
Regulation S Securities and their Successor Securities shall bear a Regulation S
Legend, subject to the following:

                         (i) subject to the following Clauses of this Section
         3.05(c), a Security or any portion thereof which is exchanged, upon
         transfer or otherwise, for a Global Security or any portion thereof
         shall bear the Securities Act Legend borne by such Global Security
         while represented thereby;

                        (ii) subject to the following Clauses of this Section
         3.05(c), a new Security which is a Definitive Security and is issued in
         exchange for a Global Security or any portion thereof, upon transfer or
         otherwise, shall bear the Securities Act Legend borne by such other
         Security, provided that, if such new Security is required pursuant to
         Section 3.05(b)(iii) or (iv) to be issued in the form of a Restricted
         Security, it shall bear a Restricted Securities Legend and, if such new
         Security is so required to be issued in the form of a Regulation S
         Security, it shall bear a Regulation S Legend;

                       (iii) Registered Securities shall not bear a Securities
         Act Legend;

                        (iv) at any time after the Securities may be freely
         transferred without registration under the Securities Act or without
         being subject to transfer restrictions pursuant to the Securities Act,
         a new


                                      -59-


<PAGE>

         Security which does not bear a Securities Act Legend may be issued in
         exchange for or in lieu of a Security (other than a Global Security) or
         any portion thereof which bears such a legend if the Trustee has
         received an Unrestricted Securities Certificate, satisfactory to the
         Trustee and duly executed by the Holder of such legended Security or
         his attorney duly authorized in writing, and after such date and
         receipt of such certificate, the Trustee shall authenticate and deliver
         such a new Security in exchange for or in lieu of such other Security
         as provided in this Article III;

                         (v) a new Security which does not bear a Securities Act
         Legend may be issued in exchange for or in lieu of a Security (other
         than a Global Security) or any portion thereof which bears such a
         legend if, in the Issuer's judgment, placing such a legend upon such
         new Security is not necessary to ensure compliance with the
         registration requirements of the Securities Act, and the Trustee, at
         the direction of the Issuer, shall authenticate and deliver such a new
         Security as provided in this Article III; and

                        (vi) notwithstanding the foregoing provisions of this
         Section 3.05(c), a Successor Security of a Security that does not bear
         a particular form of Securities Act Legend shall not bear such form of
         legend unless the Issuer has reasonable cause to believe that such
         Successor Security is a "restricted security" within the meaning of
         Rule 155, in which case the Trustee, at the direction of the Issuer,
         shall authenticate and deliver a new Security bearing a Restricted
         Securities Legend in exchange for such Successor Security as provided
         in this Article III.

                  (d) Exchanges of Global Security for Definitive Security.
Transfers of Global Securities shall be by delivery. The Book-Entry Depositary
and the Issuer have agreed that the Global Securities shall only be delivered in
the circumstances described in the Deposit Agreement. Notwithstanding any other
provision in this Indenture, no Global Security may be exchanged in whole or in
part for Definitive Securities unless (i) Euroclear and Clearstream each
notifies the Issuer or the Book-Entry Depositary in writing that it (or its
nominee) is unwilling or unable to continue to act as, or ceases to be, a
clearing agency registered under the Exchange Act, and, in either case, a
successor registered as a clearing agency under the Exchange Act is not
appointed by the Issuer within 90 days, (ii) at any time if the Issuer
determines that the Global Securities


                                      -60-

<PAGE>



(in whole but not in part) should be exchanged for Definitive Securities;
provided, that (x) such exchange is required by (A) any applicable law or (B)
any event beyond the Issuer's control or (y) payments of interest on any Global
Security, Depositary Interest or beneficial interest are, or would become,
subject to any deduction or withholding for taxes, (iii) at any time after the
consummation of the Exchange Offer, if the owner of a beneficial interest
requests such exchange in writing delivered to Euroclear or Clearstream and
through Euroclear or Clearstream to the Book-Entry Depositary and the Trustee,
or (iv) if the Book-Entry Depositary is at any time unwilling or unable to
continue as Book-Entry Depositary and a successor Book-Entry Depositary is not
appointed by the Issuer within 90 days. Upon the occurrence of any of the
preceding events, Definitive Securities shall be issued in such names as the
Book-Entry Depositary shall instruct the Trustee based on the instructions of
Euroclear or Clearstream.

                  (e) If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Book-Entry Depositary or its nominee to the Trustee, as Security Registrar, for
exchange or cancelation as provided in this Article III. If any Global Security
is to be exchanged for other Securities or canceled in part, or if another
Security is to be exchanged in whole or in part for a beneficial interest in any
Global Security, then either (i) such Global Security shall be so surrendered
for exchange or cancelation as provided in this Article III or (ii) the
principal amount at maturity thereof shall be reduced or increased by an amount
equal to the portion thereof to be so exchanged or canceled, or equal to the
principal amount at maturity of such other Security to be so exchanged for a
beneficial interest therein, as the case may be, by means of an appropriate
adjustment made by (x) the Book-Entry Depositary as directed by the Trustee in
such Book-Entry Depositary's book-entry system to the corresponding Depositary
Interest and (y) the Common Depositary as directed by the Book-Entry Depositary
in accordance with the Deposit Agreement to the corresponding Depositary
Interest, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct Euroclear or Clearstream (as applicable) or their authorized
representatives to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Security, the Trustee shall, subject to
Section 3.05(b) and as otherwise provided in this Article III, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of,


                                      -61-

<PAGE>



and registered (if applicable) in such names as may be directed by, the
Book-Entry Depositary or its authorized representative. Upon the request of the
Trustee in connection with the occurrence of any of the events specified in the
preceding paragraph, the Issuer shall promptly make available to the Trustee a
reasonable supply of Securities that are not in the form of Global Securities.
The Trustee shall be entitled to rely upon any order, direction or request of
the Book-Entry Depositary or Euroclear or Clearstream or any of their authorized
representatives which is given or made pursuant to this Article III if such
order, direction or request is given or made in accordance with the Deposit
Agreement with respect to the Book-Entry Depositary and the Applicable
Procedures with respect to Euroclear and Clearstream.

                  SECTION 3.06. Mutilated, Destroyed, Lost and Stolen
Securities. If any mutilated Security is surrendered to the Trustee, the Issuer
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount at maturity and
bearing a number not contemporaneously outstanding.

                  If there shall be delivered to the Issuer and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of written
notice to the Issuer or the Trustee that such Security has been acquired by a
bona fide purchaser, the Issuer shall execute and the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of like tenor and principal amount at maturity and bearing a number not
contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Issuer in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section, the
Issuer 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) connected therewith.

                  Every new Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall


                                      -62-

<PAGE>



constitute an original additional contractual obligation of the Issuer, whether
or not the destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                  SECTION 3.07. Payment of Interest; Interest Rights Preserved.
Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the bearer thereof
on the Interest Payment Date in the case of a Global Security in bearer form
and, in the case of a Definitive Security, to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest.

                  Any interest (including Special Interest) on any Security
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") shall (a) bear
interest at the rate per annum stated in the form of Security included herein
(to the extent that the payment of such interest shall be legally enforceable),
and (b) forthwith cease to be payable to the bearer thereof on such Interest
Payment Date with respect to a Global Security in bearer form and, with respect
to a Definitive Security, to the Holder on the relevant Regular Record Date by
virtue of having been such Holder, and, in each case, such Defaulted Interest
may be paid by the Issuer, at its election in each case, as provided in Clause
(a) or (b) below:

                  (a) The Issuer may elect to make payment of any Defaulted
         Interest to the bearer of such Security on any Special Payment Date (as
         defined below) with respect to any Global Security in bearer form and,
         with respect to a Definitive Security, to the Persons in whose names
         the Securities (or their respective Predecessor Securities) 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 Issuer shall notify the Trustee in writing of the
         amount of Defaulted Interest proposed to be paid on each Security and
         the date of the proposed payment, and at the same time the Issuer shall


                                      -63-

<PAGE>



         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 which shall be not more than 15 days and not 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 Issuer of such Special Record
         Date and, in the name and at the expense of the Issuer, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to each Holder, 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 so mailed, such Defaulted
         Interest shall be paid, with respect to any Definitive Security, to the
         Persons in whose names the Securities (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         Clause (b). As used in this Clause (a), "Special Payment Date" means
         the date on which Defaulted Interest is paid to the Holder.

                  (b) The Issuer may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Securities may be listed, and upon
         such notice as may be required by such exchange, if, after notice given
         by the Issuer 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
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                  SECTION 3.08. Persons Deemed Owners. Prior to due presentment
of a Security for registration of transfer, the Issuer, the Parent Guarantor,
the Subsidiary Guarantor,


                                      -65-

<PAGE>



the Trustee and any agent of the Issuer, the Parent Guarantor, the Subsidiary
Guarantor or the Trustee may treat the Person in whose name a Definitive
Security is registered as the owner of such Security and may treat the bearer of
a Global Security as the owner of such Security, in each case, for the purpose
of receiving payment of principal of and premium, if any, and (subject to
Section 3.07) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Issuer, the Parent
Guarantor, the Subsidiary Guarantor, the Trustee nor any agent of the Issuer,
the Parent Guarantor, the Subsidiary Guarantor or the Trustee shall be affected
by notice to the contrary.

                  SECTION 3.09. Cancelation. All Securities surrendered for
payment, redemption, registration of transfer, exchange or pursuant to any Offer
to Purchase pursuant to Section 10.13 or 10.17 shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly
canceled by it. The Issuer may at any time deliver to the Trustee for
cancelation any Securities previously authenticated and delivered hereunder
which the Issuer may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in accordance with its
standard procedures or as directed by an Issuer Order; provided, however, that
the Trustee shall not be required to destroy such Securities.

                  SECTION 3.10. Computation of Interest. Interest on the
Securities shall be computed on the basis of a 360-day year of twelve 30-day
months, provided, however, that Special Interest on Original Securities shall be
computed on the basis of a 365- or 366-day year, as the case may be, and the
number of days actually elapsed.

                  SECTION 3.11. ISIN Numbers and Common Code Numbers. The Issuer
in issuing Securities may use "ISIN" and "Common Code" numbers (if then
generally in use) in addition to serial numbers; if so, the Trustee shall use
such "ISIN" and "Common Code" numbers in addition to serial numbers in notices
of redemption and repurchase as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such
"ISIN" and "Common Code" numbers either as printed on the Securities or as
contained in any notice of a


                                      -65-

<PAGE>



redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Securities, and any such redemption
or repurchase shall not be affected by any defect in or omission of such "ISIN"
and "Common Code" numbers.

                  SECTION 3.12. Additional Securities. Subject to Article X of
this Indenture, the Issuer may authorize the issuance of Additional Securities.
All Securities originally issued on the date of this Indenture and any
Additional Securities originally issued after the date of Securities for all
purposes under this Indenture.

                  Additional Securities shall be issued, authenticated and
delivered in accordance with the provisions of Section 3.03 and shall be
entitled to the benefits of the Guarantees of the Guarantors to the same extent
as all other Securities. The Issuer shall specify in the Issuer Order pursuant
to Section 3.03 the aggregate principal amount of Additional Securities and
shall certify that the issuance complies with the requirements of the Indenture,
including Article X. The Issuer shall be entitled to issue Additional Securities
initially as Original Securities or as Exchange Securities. If Additional
Securities are issued as Original Securities, they may be exchanged for Exchange
Securities in accordance with this Indenture and the applicable Exchange and
Registration Rights Agreement.


                                   ARTICLE IV

                             Guarantee Of Securities

                  SECTION 5.01. Guarantee. Subject to the provisions of this
Article Four, the Guarantors hereby fully, unconditionally and irrevocably
guarantee to each Holder and to the Trustee on behalf of the Holders: (i) the
due and punctual payment of the principal of, premium, if any, on and interest
(including Special Interest) on each Security, when and as the same shall become
due and payable, whether at maturity, by acceleration or otherwise, the due and
punctual payment of interest on the overdue principal of and interest, if any,
on the Securities, to the extent lawful, and the due and punctual performance of
all other obligations of the Issuer to the Holders or the Trustee, all in
accordance with the terms of such Security and this Indenture and (ii) in the
case of any extension of time of payment or renewal of any Securities or any of
such other obligations, that the same will be promptly paid in full


                                      -66-

<PAGE>



when due or performed in accordance with the terms of the extension or renewal,
at Stated Maturity, by acceleration or otherwise. The Guarantors hereby waive
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Issuer, any right to require a proceeding
first against the Issuer, the benefit of discussion, protest or notice with
respect to any such Security or the debt evidenced thereby and all demands
whatsoever, and covenants that this Securities Guarantee will not be discharged
as to any such Security except by payment in full of the principal thereof and
interest thereon and as provided in Section 12.01 and Section 12.02 (subject to
Section 12.06). The maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Five for the purposes of this Article Four.
In the event of any declaration of acceleration of such obligations as provided
in Article Five, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purpose of this
Article Four. In addition, without limiting the foregoing provisions, upon the
effectiveness of an acceleration under Article Five, the Trustee shall promptly
make a demand for payment on the Securities under the Guarantee provided for in
this Article Four.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or either Guarantor, or any
custodian, receiver, liquidator, trustee, sequestrator or other similar official
acting in relation to the Issuer or either Guarantor, any amount paid to the
Trustee or such Holder in respect of a Security, this Securities Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect.
The Guarantors further agree, to the fullest extent that they may lawfully do
so, that, as between them, on the one hand, and the Holders and the Trustee, on
the other hand, the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Five hereof for the purposes of this
Securities Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Guarantors hereby irrevocably waive any claim or other rights which
they may now or hereafter acquire against the Issuer that arise from the
existence, payment, performance or enforcement of their obligations under this
Securities


                                      -67-

<PAGE>



Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, any
right to participate in any claim or remedy of the Holders against the Issuer or
any collateral which any such Holder or the Trustee on behalf of such Holder
hereafter acquires, whether or not such claim, remedy or right arises in equity,
or under contract, statute or common law, including, without limitation, the
right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or security on
account of such claim or other rights. If any amount shall be paid to either
Guarantor in violation of the preceding sentence and the principal of, premium,
if any, and accrued interest on the Securities shall not have been paid in full,
such amount shall be deemed to have been paid to such Guarantor for the benefit
of, and held in trust for the benefit of, the Holders, and shall forthwith be
paid to the Trustee for the benefit of the Holders to be credited and applied
upon the principal of, premium, if any, and accrued interest on the Securities.
The Guarantors acknowledge that they will receive direct and indirect benefits
from the issuance of the Securities pursuant to this Indenture and that the
waivers set forth in this Section 5.01 are knowingly made in contemplation of
such benefits.

                  The Guarantee set forth in this Section 5.01 shall not be
valid or become obligatory for any purpose with respect to a Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 5.02. Obligations Unconditional. Subject to Section
5.05, nothing contained in this Article Four or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Guarantors and
the holders of the Securities, the obligation of the Guarantors, which is
absolute and unconditional, upon failure by the Issuer, to pay to the holders of
the Securities the principal of, premium, if any, and interest on the Securities
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Securities and creditors of either Guarantor, nor shall anything herein or
therein prevent the holder of any Securities or the Trustee on their behalf from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article Four will restrict the right of the Trustee


                                      -68-

<PAGE>



or the holders of the Securities to take any action to declare the Guarantee to
be due and payable prior to the Stated Maturity of the Securities pursuant to
Section 5.02 or to pursue any rights or remedies hereunder.

                  SECTION 5.03. Notice to Trustee. The Guarantors shall give
prompt written notice to the Trustee of any fact known to either Guarantor which
would prohibit the making of any payment to or by the Trustee in respect of the
Securities Guarantee pursuant to the provisions of this Article Four.

                  SECTION 5.05. Release of Subsidiary Guarantor. The Subsidiary
Guarantor shall be automatically and unconditionally released and discharged
from its obligations under this Securities Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Parent Guarantor, of all of
the Parent Guarantor's and each Restricted Subsidiary's Capital Stock in, or all
or substantially all the assets of, the Subsidiary Guarantor (which sale,
exchange or transfer is not prohibited by this Indenture) or (ii) at any time,
so long as in the case of this clause (ii) Standard & Poor's Corporation is
notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications. Upon the release and
discharge of the Subsidiary Guarantor from its obligations under the Securities
Guarantee pursuant to this Section 5.05, the Subsidiary Guarantor shall also be
released and discharged from any other obligations it has under this Indenture
in its capacity as Subsidiary Guarantor, provided that no such release and
discharge shall affect any obligation of the Subsidiary Guarantor in its
capacity as a Restricted Subsidiary of the Guarantor.

                                    Remedies

         individually or in the aggregate, in excess of $10 million, whether
         such indebtedness now exists or shall hereafter be created, which

         maturity thereof, or shall have resulted in excess of $10 million of
         indebtedness becoming or being declared due and payable prior to the
         date on which it would otherwise have become due and payable; or

         order for relief or any such other decree or order unstayed and in
         effect for a period of 60 consecutive days; or

                  (i) the commencement by either Guarantor, the Issuer or any
         Significant Subsidiaries of a voluntary case or proceeding under any
         applicable bankruptcy, insolvency, reorganization or other similar law
         or of any other case or proceeding to be adjudicated a bankrupt or
         insolvent, or the consent by it to the entry of a decree or order for
         relief in respect of either Guarantor, the Issuer or any Significant
         Subsidiaries in an involuntary case or proceeding under any applicable
         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 law, or the consent by it
         to the filing of such petition or to the appointment of or taking
         possession


                                      -71-

         by a custodian, receiver, liquidator, assignee, trustee, sequestrator
         or other similar official of either Guarantor, the Issuer or any
         Significant Subsidiaries or of any substantial part of its property, or
         the making by it of an assignment for the benefit of creditors, or the
         admission by it in writing of its inability to pay its debts generally
         as they become due, or the taking of corporate action by either
         Guarantor, the Issuer or any Significant Subsidiaries in furtherance of
         any such action; provided that this clause (i) shall not apply to any
         actions in connection with the winding up or liquidation of the
         Guarantors or the Issuer to be effected after the Person then
         constituting such Guarantors or the Issuer shall cease to be such
         Guarantors or the Issuer following a transaction governed by the
         provisions of Article VIII.

                  SECTION 5.02. Acceleration of Maturity; Rescission and
Annulment. If an Event of Default (other than an Event of Default specified in
Section 5.01(h) or (i)) occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in principal amount at maturity
of the Outstanding Securities may declare the principal amount at maturity of
all the Securities to be due and payable immediately, by a notice in writing to
the Issuer (and to the Trustee if given by Holders), and upon any such
declaration such principal amount and any accrued interest shall become
immediately due and payable. If an Event of Default specified in Section 5.01(h)
or (i) occurs, the principal amount of and any accrued interest on the
Securities then Outstanding shall ipso facto become immediately due and payable
without any declaration or other Act on the part of the Trustee or any Holder.

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due based on
acceleration has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount at maturity of the
Outstanding Securities, by written notice to the Issuer and the Trustee, may
rescind and annul such declaration and its consequences if:

                  (1) the Issuer has paid or deposited with the Trustee a sum
         sufficient to pay

                           (A) all overdue interest on all Securities,

                           (B) the principal amount of (and premium, if any, on)
                  any Securities which have become due


                                      -72-

<PAGE>



                  otherwise than by such declaration of acceleration (including
                  any Securities required to have been purchased on the Purchase
                  Date pursuant to an Offer to Purchase made by the Issuer) and
                  interest thereon at the rate borne by the Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate borne by
                  the Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

         and

                  (2) all Events of Default, other than the non-payment of the
         principal of Securities which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 5.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                  SECTION 5.03. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Issuer covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof or, with
         respect to any Security required to have been purchased pursuant to an
         Offer to Purchase made by the Issuer, at the Purchase Date thereof,

the Issuer will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
provided by the Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of


                                      -73-

<PAGE>



collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

                  If the Issuer fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Issuer or any other obligor upon the Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Issuer or any other obligor upon the Securities,
wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such appropriate judicial proceedings as the Trustee shall
deem most effective to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

                  SECTION 5.05. Trustee May File Proofs of Claim. In case of any
judicial proceeding relative to the Issuer (or any other obligor upon the
Securities), its property or its creditors, the Trustee shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have claims of the
Holders and the Trustee allowed in any such proceeding. In particular, the
Trustee shall be authorized to collect and receive any moneys, securities or
other property payable or deliverable upon the exchange of the Securities 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 it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.07.

                  No provision of this Indenture shall be deemed to authorize
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


                                      -75-

<PAGE>



Securities 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; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors or
other similar committee.

                  SECTION 5.05. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

                  SECTION 5.06. Application of Money Collected. Any money
collected by the Trustee pursuant to this Article shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal (or premium, if any) or
interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 6.07; and

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities 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 Securities for
         principal (and premium, if any) and interest, respectively.

                  SECTION 5.07. Limitation on Suits. No Holder of any Security
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;


                                      -75-

<PAGE>



                  (2) the Holders of not less than 25% in aggregate principal
         amount at maturity of the Outstanding Securities shall have made
         written request to the Trustee to institute proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered and, if requested,
         provided to the Trustee reasonable indemnity against the costs,
         expenses and liabilities to be incurred in compliance with such
         request;

                  (5) the Trustee for 60 days after its receipt of such notice,
         request and offer and, if requested, provision of indemnity has failed
         to institute any such proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount at maturity of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

                  SECTION 5.08. Unconditional Right of Holders To Receive
Principal, Premium and Interest. Notwithstanding any other provision in this
Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of (and premium, if any)
and (subject to Section 3.07) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date or, in the case of an Offer to Purchase made by the Issuer and
required to be accepted as to such Security, on the Purchase Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

                  SECTION 5.09. 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


                                      -76-

<PAGE>



determination in such proceeding, the Issuer, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                  SECTION 5.10. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.06, 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 5.11. Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder of any Security 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 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.

                  SECTION 5.12. Control by Holders. The Holders of a majority in
principal amount at maturity of the Outstanding Securities 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; provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or expose the Trustee to personal liability
         (as determined in the sole discretion of the Trustee), and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  SECTION 5.13. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount at maturity of the Outstanding
Securities may on


                                      -77-

<PAGE>



behalf of the Holders of all the Securities by written notice to the Trustee
waive any past default hereunder and its consequences, except a default

                  (1) in the payment of the principal of (or premium, if any) or
         interest on any Security (including any Security which is required to
         have been purchased pursuant to an Offer to Purchase which has been
         made by the Issuer), or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected or

                  (3) arising from failure to purchase any Security tendered
         pursuant to Sections 10.13 and 10.17 of this Indenture.

                  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 impair any right consequent thereon.

                  SECTION 5.15. 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 such suit, and may assess costs against any such party litigant, in the
manner and to the extent provided in the Trust Indenture Act; provided that
neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any
suit instituted by the Issuer or the Parent Guarantor; further provided, that
the provisions of this Section 5.15 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Holder or group of Holders holding
more than 10% in aggregate principal amount at maturity of the Outstanding
Securities, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of, or premium, if any, or interest on any Security on
or after the respective due dates expressed in such Security.

                  SECTION 5.15. Waiver of Stay or Extension Laws. Each of the
Issuer and the Parent Guarantor 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


                                      -78-

<PAGE>



claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and each of the Issuer and the Parent
Guarantor (to the extent that it may lawfully do so) 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.


                                   ARTICLE VI

                                   The Trustee

                  SECTION 6.01. Certain Duties and Responsibilities. (a) Except
during the continuance of an Event of Default,

                  (1) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants, duties or obligations shall be read into this
         Indenture against the Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but 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 be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.

                  (b) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

                  (c) No provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own wilful misconduct, except that



                                      -79-

<PAGE>



                  (1) this Subsection shall not be construed to limit the effect
         of Subsection (a) of this Section;

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

                  (3) the 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 a majority in principal amount at maturity
         of the Outstanding Securities 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; and

                  (5) 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.

                  (d) 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 Section.

                  SECTION 6.02. Notice of Defaults. The Trustee shall give the
Holders notice of any default hereunder known to the Trustee as and to the
extent provided by the Trust Indenture Act; provided, however, that in the case
of any default of the character specified in Section 5.01(e), no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default.

                  SECTION 6.03. Certain Rights of Trustee. Subject to the
provisions of Section 6.01:

                  (a) the Trustee may conclusively rely and shall be completely
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,


                                      -80-

<PAGE>



         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document believed by it to be genuine
         and to have been signed or presented by the proper party or parties;

                  (b) any request or direction of the Issuer mentioned herein
         shall be sufficiently evidenced by a Issuer Request or Issuer Order and
         any resolution of the Board of Directors may be sufficiently evidenced
         by a Board Resolution;

                  (c) 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 any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, request from the Issuer and be
         completely protected in relying upon an Officers' Certificate received
         in response to such request;

                  (d) the Trustee may consult with counsel of its selection and
         the written 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;

                  (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 offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction reasonably
         satisfactory to the Trustee;

                  (f) 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 may (but shall have no
         obligation to) make such further inquiry or investigation into such
         facts or matters as it may see fit, and, if the Trustee shall determine

         appointed with due care by it hereunder;

                  (h) the Trustee shall not be liable with respect to any action

         direction of Holders of Outstanding Securities as provided in Sections
         5.02, 5.12 and 5.13 hereof; and

                  (i) for all purposes under this Indenture, the Trustee shall
         not be deemed to have notice of any Event of Default unless a
         Responsible Officer of the Trustee has actual knowledge thereof or
         unless written notice of any event which is in fact such a default is
         received by the Trustee at the Corporate Trust Office of the Trustee,
         and such notice references the Securities and this Indenture.

the Parent Guarantor with the same rights it would have if it were not Trustee,
Paying Agent, Security Registrar or such other agent.

                  SECTION 6.06. Money Held in Trust. 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


                                      -82-

         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the

         expenses of enforcing this Indenture against the Issuer or the Parent
         Guarantor (including, without limitation, this Section 6.07) and of
         defending itself against any claim (whether asserted by any Holder or
         the Issuer or the Parent Guarantor) or liability in connection with the

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(h) or Section

                  SECTION 6.10. Resignation and Removal; Appointment of
Successor. (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11, at which
time the retiring Trustee shall be fully discharged from its obligations
hereunder.

                  (b) The Trustee may resign at any time by giving written
notice thereof to the Issuer. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (c) The Trustee may be removed at any time by Act of the
Holders of a majority in principal amount at maturity of the Outstanding

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 6.08 after
         written request therefor by the Issuer or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 6.09

         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuer by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.15, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

<PAGE>



                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Issuer, by a Board Resolution, shall promptly appoint a successor
Trustee. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount at maturity of the Outstanding
Securities delivered to the Issuer and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Issuer. If no successor Trustee shall have been so appointed by the Issuer
or the Holders and accepted appointment in the manner hereinafter provided, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Issuer shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 1.06. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

                  SECTION 6.11. Acceptance of Appointment by Successor. Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Issuer and to the retiring Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Issuer or the successor Trustee,
such retiring Trustee shall, upon payment of all sums owing to the Trustee under
Section 6.07, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Issuer shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

                  No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

                  SECTION 6.12. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee 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 Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided that such corporation shall be otherwise
qualified and eligible under this Article. In case any Securities shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities.

                  SECTION 6.13. Preferential Collection of Claims Against Issuer
or Guarantors. If and when the Trustee shall be or become a creditor of the
Issuer or either Guarantor (or any other obligor upon the Securities), the
Trustee shall be subject to the provisions of the Trust Indenture Act regarding
the collection of claims against the Issuer or Parent Guarantor (or any such
other obligor).

                  SECTION 6.15. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to the Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 3.06, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Issuer and shall at all times be a corporation organized and doing business
under the laws of the United States of


                                      -87-

America, any State thereof or the District of Columbia, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal
or State authority. If such Authenticating Agent publishes reports of condition
at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent;
provided, such corporation shall be otherwise eligible under this Section.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Issuer. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Issuer. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Issuer and shall give notice of such
appointment in the manner provided in Section 1.06 to all Holders of Securities.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its


                                      -88-

<PAGE>



services under this Section, and the Trustee shall be entitled to be reimbursed
for such payments, subject to the provisions of Section 6.07.

                  If an appointment is made pursuant to this Section, the
Securities may have endorsed thereon, in lieu of the Trustee's certificate of
authentication, an alternative certificate of authentication in the following
form:

                  This is one of the Securities referred to in the
within-mentioned Indenture.

Guarantor, shall exclude and withhold from each payment of principal and
interest and other amounts due hereunder or under the Securities or the
Securities Guarantee 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 Securities or the Securities Guarantee, 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 Securities, that it will furnish to the Holders of the Securities
such forms or certificates as are necessary or appropriate to provide the
information described in Section 10.09(c)(i) hereof or make the declaration or
claim described in Section 10.09(c)(ii) hereof, 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 Security
appropriate documentation showing the


                                      -89-

Holders may reasonably request from time to time.

protections afforded to the Trustee pursuant to this Article Six shall also be
afforded to such Paying Agent, Authenticating Agent,
transfer agent, or Registrar.

         immediately prior to the transaction;

                  (5) if, as a result of any such transaction, property or
         assets of the Parent Guarantor or any Subsidiary would become subject
         to a Lien prohibited by Section 10.15, the Parent Guarantor or the
         successor entity to the Parent Guarantor shall have secured the
         Securities as required by said covenant; and

                  (5) in the event that the continuing Person is incorporated in
         a jurisdiction other than the United States or the jurisdiction in
         which such Person was incorporated immediately prior to such
         transaction, (A) the Issuer delivers to the Trustee an Opinion of
         Counsel stating that the obligations of the continuing Person under the
         Indenture are enforceable under the laws of the new jurisdiction of its
         incorporation to the same extent as the obligations of the Issuer or
         the Parent Guarantor, as the case may be, under the Indenture
         immediately prior to such transaction; (B) the continuing Person agrees
         in writing to submit to jurisdiction and appoints an agent for the
         service of process, each under terms substantially similar to the terms
         contained in the Indenture with respect to the Issuer or such
         Guarantor, as the case may be; (C) the continuing Person agrees in
         writing to pay Additional Amounts as provided under this Indenture
         under Section 10.09 with respect to the Issuer or such Guarantor, as
         the case may be, except that such Additional Amount shall relate to any
         withholding tax whatsoever regardless of any change of law (subject to
         exceptions substantially similar to those contained in Section 10.09);
         (D) the Board of Directors of the Parent Guarantor determines in good
         faith that such transaction will have no material adverse effect on any
         Holder and a Board Resolution to that effect is delivered to the
         Trustee; and (E) the principal purpose of the continuing Person being
         incorporated in such jurisdiction is to obtain tax benefits for such
         Guarantor, the Issuer, their direct and indirect stockholders or the
         Holders.

                  SECTION 8.02. Successor Substituted. Upon any consolidation of
either Guarantor or the Issuer with, or merger of either Guarantor or the Issuer
with or into, any other Person or any conveyance, transfer or lease of the
properties and assets of either Guarantor or the Issuer substantially as an
entirety in accordance with Section 8.01, the successor Person formed by such

merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, such
Guarantor or the Issuer, as applicable, under this Indenture with the same
effect as if such successor Person had been named as such Guarantor or the
Issuer herein, and thereafter, except in the case of a lease, the predecessor
Person shall be relieved of all obligations and covenants under this Indenture
and the Securities.

                             Supplemental Indentures

                  SECTION 9.01. Supplemental Indentures Without Consent of
Holders. Without the consent of any Holders, the Issuer and the Guarantors, each
when authorized by a Board Resolution, and the Trustee, at any time and from
time to time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the Issuer
         or either Guarantor and the assumption by any such successor of the
         covenants of the Issuer or such Guarantor herein and in the Securities;
         or

                  (2) to add to the covenants of the Issuer or either Guarantor
         for the benefit of the Holders, or to surrender any right or power
         herein conferred upon the Issuer or either Guarantor; or

                  (3) to secure the Securities pursuant to the requirements of
         Section 10.15 or otherwise; or

                  (5) to modify, eliminate or add to the provisions of this
         Indenture to such extent as shall be necessary to comply with any
         requirement of the Commission in order to effect qualification of this
         Indenture under the Trust Indenture Act in connection with the issuance
         of Exchange Securities or Registered Securities or thereafter to
         maintain the qualification of this Indenture under the Trust Indenture
         Act; or

                  (5) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision
         herein, or to make any other provisions with respect to matters or
         questions arising under this Indenture which shall not


                                      -95-

<PAGE>



         be inconsistent with the provisions of this Indenture; provided that
         such action pursuant to this Clause (5) shall not adversely affect the
         interests of the Holders in any material respect; or

                  (6) to provide for uncertificated Securities in addition to or
         in place of certified Securities.

                  SECTION 9.02. Supplemental Indentures with Consent of Holders.
With the written consent of the Holders of not less than a majority in aggregate
principal amount at maturity of the Outstanding Securities, by Act of said
Holders delivered to the Issuer and the Trustee, and consistent with Section
5.13, the Issuer and the Guarantors, each when authorized by a Board Resolution,
and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders under this Indenture; provided, however, that
no such supplemental indenture shall, without the written consent of the Holder
of each Outstanding Security affected thereby,

                  (1) change the Stated Maturity of the principal of, or any
         installment of interest on, any Security, or reduce the principal
         amount thereof or the rate of interest thereon or any premium payable
         thereon, or change the coin or currency in which, any Security or any
         premium or interest thereon is payable, or impair the right to
         institute suit for the enforcement of any such payment on or after the
         Stated Maturity thereof (or, in the case of redemption, on or after the
         Redemption Date) or, in the case of an Offer to Purchase which has been
         made, on or after the applicable Purchase Date, or

                  (2) reduce the percentage in principal amount at maturity of
         the Outstanding Securities, the consent of whose Holders is required
         for any such supplemental indenture, or the consent of whose Holders is
         required for any waiver (of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences)
         provided for in this Indenture, or

                  (3) modify any of the provisions of this Section, Section 5.13
         or Section 10.20, except to increase any such percentage or to provide
         that certain other provisions of this Indenture cannot be modified or


                                      -95-

<PAGE>



         waived without the consent of the Holder of each Outstanding Security
         affected thereby, or

                  (5) following the making of an Offer with respect to an Offer
         to Purchase pursuant to Sections 10.13 or 10.17, modify the provisions
         of this Indenture with respect to such Offer to Purchase in a manner
         materially adverse to such Holder, or

                  (5) release either Guarantor from its Securities Guarantee,
         except for a release of the Subsidiary Guarantor pursuant to Section
         5.05.

                  It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

                  SECTION 9.03. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.01) shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but 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.

                  SECTION 9.05. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby.

                  SECTION 9.05. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act.

                  SECTION 9.06. Reference in Securities to Supplemental
Indentures. Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as


                                      -96-

<PAGE>



to any matter provided for in such supplemental indenture. If the Issuer shall
so determine, new Securities so modified as to conform, in the opinion of the
Trustee and the Issuer, to any such supplemental indenture may be prepared and
executed by the Issuer and authenticated and delivered by the Trustee in
exchange for Outstanding Securities.


                                    ARTICLE X

                                    Covenants

                  SECTION 10.01. Payment of Principal, Premium and Interest. The
Issuer will duly and punctually pay the principal of and premium, if any, and
interest on the Securities in accordance with the terms of the Securities and
this Indenture. Payments of principal, interest and premium, if any, shall be
made in Euros.

                  SECTION 10.02. Maintenance of Office or Agency. The Issuer
will maintain in the Borough of Manhattan, the City of New York, New York, an
office or agency where Securities may be presented or surrendered for payment,
where Securities may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Issuer in respect of the Securities and
this Indenture may be served. The Issuer 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 Issuer 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
Corporate Trust Office of the Trustee, and the Issuer hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

                  The Issuer may also from time to time designate one or more
other offices or agencies (in or outside the Borough of Manhattan, the City of
New York, New York) where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Issuer of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York, New York for such purposes. The
Issuer 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.

                  SECTION 10.03. Money for Security Payments To Be Held in
Trust. If the Issuer shall at any time act as its own Paying Agent, it will, on
or before each due date of the


                                      -97-

<PAGE>



principal of (and premium, if any) or interest on any of the Securities,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee in writing of its
action or failure so to act. As provided in Section 5.05, upon any bankruptcy or
reorganization proceeding relative to the Issuer, the Trustee shall serve as the
Paying Agent for the Securities.

                  Whenever the Issuer shall have one or more Paying Agents, it
will, prior to each due date of the principal of (and premium, if any) or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal, premium
or interest, and (unless such Paying Agent is the Trustee) the Issuer will
promptly notify the Trustee in writing of its action or failure so to act. Upon
any bankruptcy or reorganization proceeding relative to the Issuer, the Trustee
shall serve as the Paying Agent for the Securities.

                  The Issuer will cause each Paying Agent other than the Trustee
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, that
such Paying Agent will:

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest on Securities in trust for the
         benefit of the Persons entitled thereto until such sums shall be paid
         to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee written notice of any default by the
         Issuer (or any other obligor upon the Securities) in the making of any
         payment of principal (and premium, if any) or interest;

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent; and

                  (5) acknowledge, accept and agree to comply in all respects
         with the provisions of this Indenture relating


                                      -98-

<PAGE>



         to the duties, rights and obligations of such Paying Agent.

                  The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Issuer or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Issuer or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Issuer, in trust for the payment of the principal of (and
premium, if any) or interest on any Security and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Issuer on Issuer Request, or (if then held by the
Issuer) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Issuer as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Issuer cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation
in the Borough of Manhattan, the City of New York, New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Issuer.

                  SECTION 10.05. Existence. Subject to Article Eight, the
Guarantors will do or cause to be done all things necessary to preserve and keep
in full force and effect the existence, rights (charter and statutory) and
franchises of the Guarantors, the Issuer and each of the Restricted
Subsidiaries; provided, however, that the Guarantors shall not be required to
preserve any such right or franchise if either Guarantor shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of such Guarantor, the Issuer or the Restricted Subsidiaries and that the loss
thereof is not disadvantageous in any material respect to the Holders.


                                      -99-

<PAGE>



                  SECTION 10.05. Maintenance of Properties. The Guarantors will
cause all properties used or useful in the conduct of their business or the
business of the Issuer or any Restricted Subsidiary to be maintained and kept in
good condition, repair and working order 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 Guarantors may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent either Guarantor from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the reasonable judgment of the Parent Guarantor, desirable
in the conduct of its business or the business of the Issuer or any Restricted
Subsidiary and not disadvantageous in any material respect to the Holders.

                  SECTION 10.06. Payment of Taxes and Other Claims. Neither
Guarantor will pay or discharge or cause to be paid or discharged, before the
same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon such Guarantor or the Issuer or any
Restricted Subsidiaries or upon the income, profits or property of such
Guarantor or the Issuer or any Restricted Subsidiaries, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of such Guarantor or the Issuer or any Restricted
Subsidiaries; provided, however, that neither Guarantor shall be required to pay
or discharge or cause to be paid or discharged any such tax, assessment, charge
or claim whose amount, applicability or validity is being contested in good
faith by appropriate proceedings.

                  SECTION 10.07. Maintenance of Insurance. The Guarantors shall,
and shall cause the Issuer and the Restricted Subsidiaries to, keep at all times
all of their properties which are of an insurable nature insured against loss or
damage with insurers believed by the Guarantors to be responsible to the extent
that property of similar character is usually so insured by corporations
similarly situated and owning like properties in accordance with good business
practice.

                  SECTION 10.08. Limitation on Consolidated Debt. The Parent
Guarantor may not, and may not permit any Restricted Subsidiary of the Parent
Guarantor to, Incur any Debt (other than the Securities and the Securities
Guarantee) unless the ratio of (i) the aggregate


                                      -100-

<PAGE>



consolidated principal amount of Debt (which is defined to include the accreted
value of any Debt issued at a discount) of the Parent Guarantor outstanding as
of the most recent available quarterly or annual balance sheet, after giving pro
forma effect to the Incurrence of such Debt and any other Debt Incurred since
such balance sheet date and the receipt and application of the proceeds thereof,
to (ii) four (5) times the Consolidated Cash Flow Available for Fixed Charges
for the most recent fiscal quarter next preceding the Incurrence of such Debt
for which consolidated financial statements are available, determined on a pro
forma basis as if any such Debt had been Incurred and the proceeds thereof had
been applied at the beginning of such recent fiscal quarter, would be less than
7.0 to 1.0 for such period.

                  Notwithstanding the foregoing limitation, the Parent Guarantor
and any Restricted Subsidiary may Incur the following:

                  (i) Debt under Credit Facilities in an aggregate principal
         amount at any one time not to exceed $200 million, and any renewal,
         extension, refinancing or refunding thereof in an amount which,
         together with any principal amount remaining outstanding under all
         Credit Facilities, does not exceed the aggregate principal amount
         outstanding under all Credit Facilities immediately prior to such
         renewal, extension, refinancing or refunding;

                  (ii) Debt owed by the Parent Guarantor to any Restricted
         Subsidiary of the Parent Guarantor or Debt owed by a Restricted
         Subsidiary of the Parent Guarantor to the Parent Guarantor or a
         Restricted Subsidiary of the Parent Guarantor; provided, however, that
         upon either (x) the transfer or other disposition by such Restricted
         Subsidiary or the Parent Guarantor of any Debt so permitted to a Person
         other than the Parent Guarantor or another Restricted Subsidiary of the
         Parent Guarantor or (y) such Restricted Subsidiary ceasing to be a
         Restricted Subsidiary, the provisions of this clause (ii) shall no
         longer be applicable to such Debt and such Debt shall be deemed to have
         been Incurred at the time of such transfer or other disposition;

                  (iii) Debt Incurred to renew, extend, refinance or refund
         (each, a "refinancing") (x) Debt outstanding at the date hereof (after
         giving effect to the Equity Clawback) or (y) Incurred pursuant to the
         first


                                      -101-

<PAGE>



         paragraph of this Section, or clause (vi) or (vii) of this paragraph or
         (z) the Securities issued on the date hereof or Securities exchanged
         therefore, in each case, in an aggregate principal amount not to exceed
         the aggregate principal amount of and accrued interest on the Debt so
         refinanced plus the amount of any premium required to be paid in
         connection with such refinancing pursuant to the terms of the Debt so
         refinanced or the amount of any premium reasonably determined by the
         Parent Guarantor as necessary to accomplish such refinancing by means
         of a tender offer or privately negotiated repurchase, plus the expenses
         of the Parent Guarantor or the Restricted Subsidiary effecting such
         refinancing incurred in connection with such refinancing; provided,
         however, that Debt the proceeds of which are used to refinance the
         Securities or Debt which is pari passu to the Securities and the
         Security Guarantee or Debt which is subordinate in right of payment to
         the Securities and the Security Guarantee shall only be permitted if
         (A) in the case of any refinancing of the Securities or Debt which is
         pari passu to the Securities and the Security Guarantee, the
         refinancing Debt is made pari passu or subordinated to the Securities
         and the Security Guarantee, and, in the case of any refinancing of
         Subordinated Debt, the refinancing Debt constitutes Subordinated Debt
         and (B) in any case, the refinancing Debt by its terms, or by the terms
         of any agreement or instrument pursuant to which such Debt is issued,
         does not have a final stated maturity prior to the final stated
         maturity of the Debt being refinanced, and the Average Life of such new
         Debt is at least equal to the remaining Average Life of the Debt being
         refinanced (assuming that such Debt being refinanced had a final stated
         maturity three months later than its actual final stated maturity);

                  (iv) Debt in an aggregate principal amount not in excess of
         (A) two (2) times the aggregate amount of the Parent Guarantor's
         Incremental Paid-in Capital minus
         (B) $165 million;

                  (v) Debt in an aggregate principal amount not in excess of 80%
         of the aggregate amount of accounts receivable set forth on the most
         recent unaudited quarterly or audited annual financial statements of
         the Parent Guarantor and its consolidated subsidiaries filed with the
         Commission;

                  (vi) Purchase Money Debt, which is incurred for the
         construction, acquisition and improvement of


                                      -102-

<PAGE>



         Telecommunications Assets, provided that the amount of such Purchase
         Money Debt does not exceed the cost of the construction, acquisition or
         improvement of the applicable Telecommunications Assets;

                  (vii) Debt consisting of Permitted Interest Rate and
         Currency Protection Agreements; and

                  (viii) Debt not otherwise permitted to be Incurred pursuant to
         clauses (i) through (vii) above, which, together with any other
         outstanding Debt Incurred pursuant to this clause (viii), has an
         aggregate principal amount not in excess of $50 million at any time
         outstanding.

                  For purposes of determining compliance with this Section, with
respect to any item of Debt, (x) in the event that such item of Debt meets the
criteria of more than one of the types of Debt the Parent Guarantor or a
Restricted Subsidiary is permitted to Incur pursuant to the foregoing clauses
(i) through (viii), the Parent Guarantor shall have the right, in its sole
discretion, to classify such item of Debt and shall only be required to include
the amount and type of such Debt under the clause permitting the Debt as so
classified and (y) any other obligation of the obligor on such Debt (or of any
other Person who could have Incurred such Debt under this Section) arising under
any Guarantee, Lien or letter of credit supporting such Debt shall be
disregarded to the extent that such Guarantee, Lien or letter of credit secures
the principal amount of such Debt.

                  For purposes of determining compliance with any
Dollar-denominated restriction on the Incurrence of Debt denominated in a
foreign currency, the Dollar-equivalent principal amount of such
foreign-currency-denominated Debt Incurred pursuant thereto shall be calculated
based on the relevant currency exchange rate in effect on the date that such
foreign-currency-denominated Debt was Incurred, in the case of term debt, or
first committed, in the case of revolving credit debt; provided that (x) the
Dollar-equivalent principal amount of any such Debt outstanding on the date
hereof shall be calculated based on the relevant currency exchange rate in
effect on the date hereof and (y) if such Debt is Incurred to refinance other
Debt denominated in a foreign currency, and such refinancing would cause the
applicable Dollar-denominated restriction to be exceeded if calculated at the
relevant currency exchange rate in effect on the date of such refinancing, such
Dollar denominated restriction shall be deemed not to have been exceeded so long
as the principal amount of such refinancing


                                      -103-

<PAGE>



Debt does not exceed the principal amount of such Debt being refinanced. The
principal amount of any Debt Incurred to refinance other Debt, if Incurred in a
different currency from the Debt being refinanced, shall be calculated based on
the currency exchange rate applicable to the currency in which such respective
Debt is denominated that is in effect on the date of such refinancing.

                  SECTION 10.09. Additional Amounts. Payments made by the Issuer
or the Guarantors pursuant to the Securities or the Securities Guarantee will be
made without withholding or deduction for taxes unless required by law. In the
event of (x) any change that becomes effective after the date hereof in the laws
of the U.K. or Bermuda or of any political subdivision or taxing authority
thereof or therein or any change in the interpretation or administration thereof
or (y) a failure by the Issuer to list and maintain a listing of the Securities
on a "recognized stock exchange" (within the meaning of Section 851 of the U.K.
Income and Corporation Taxes Act 1988) prior to the first date upon which
interest is required to be paid hereunder (a "Listing Failure"), the effect of
which is to require the withholding or deduction by the Issuer or the Guarantors
pursuant to the Securities or the Securities Guarantee, respectively, of any
amount for taxes that would not have been required to be withheld or deducted
absent such change or Listing Failure, as the case may be, the Issuer or the
Guarantors will pay, to the extent they may then lawfully do so, such additional
amounts ("Additional Amounts") as may be necessary in order that every net
payment of the principal of and interest on the Securities, after deduction for
withholding for or on account of any future tax, assessment or other
governmental charge will not be less than the amount provided for in the
Securities to be then due and payable; provided, however, that the foregoing
obligation to pay Additional Amounts shall not apply in respect of:

                  (i) any tax, withholding, assessment or other governmental
         charge which would not have been imposed but for (x) the existence of
         any present or former connection between such holder (or between a
         fiduciary, settlor, beneficiary, member or shareholder of, or possessor
         of a power over, such holder, if such holder is an estate, trust,
         partnership or corporation) and the U.K. or Bermuda or any political
         subdivision or taxing authority thereof including, without limitation,
         such holder (or such fiduciary, settlor, beneficiary, member,
         shareholder or possessor) being or having been a citizen or resident
         thereof or being or having been present or engaged in trade or business
         therein or


                                      -105-

<PAGE>



         having or having had a permanent establishment therein or (y) the
         presentation of a Security or a Securities Guarantee (where
         presentation is required) for payment on a date more than 30 days after
         the date on which such payment became due and payable or the date on
         which payment thereof is duly provided for, whichever occurs later,
         except for Additional Amounts with respect to Taxes that would have
         been imposed had the holder presented the Security for payment within
         such 30-day period;

                  (ii) any estate, inheritance, gift, sale, transfer or personal
         property tax;

                  (iii) any tax, assessment or other governmental charge that is
         withheld by reason of the failure to timely comply by the holder or the
         beneficial owner of the Security with a request in writing of the
         Issuer or the Parent Guarantor (which request shall be furnished to the
         Trustee) (x) to provide information concerning the nationality,
         residence or identity of the holder or such beneficial owner or (y) to
         make any declaration or other similar claim or satisfy any information
         or reporting requirement, which, in the case of (x) or (y), is required
         or imposed by a statute, treaty, regulation or administrative practice
         of the taxing or domicile jurisdiction as a precondition to exemption
         from or reduction of all or part of such tax, assessment or other
         governmental charge; provided, however, that this clause (iii) shall
         not apply to limit the Issuer's or Guarantors' obligation to pay
         Additional Amounts if the completing and filing of the information
         described in subclause (x) or the declaration or other claim described
         in subclause (y) would be materially more onerous in form, in procedure
         or in substance of information disclosed, in comparison to the
         information reporting requirements imposed under U.S. tax law with
         respect to Forms 1001, W-8 and W-9; or

                  (iv) any tax, withholding, assessment or other governmental
         charge resulting from a Listing Failure with respect to any Security
         issued in the form of a Definitive Security pursuant to the terms of
         the Deposit Agreement and this Indenture; or

                  (v) any combination of items (i), (ii), (iii) and (iv) above;
         nor shall Additional Amounts be paid with respect to any payment of the
         principal of, or any interest on, any Security or Securities Guarantee
         to


                                      -105-

<PAGE>



         any holder who is not the sole beneficial owner of such Security or
         Securities Guarantee or is a fiduciary or partnership, but only to the
         extent that a beneficial owner, a beneficiary or a settlor with respect
         to a fiduciary or a member of the partnership would not have been
         entitled to the payment of the Additional Amount had the beneficial
         owner, beneficiary, settlor or member of such partnership received
         directly its beneficial or distributive share of the payment.

                  At least 30 days prior to each date on which any payment under
or with respect to the Securities is due and payable, if the Issuer or the
Guarantors will be obligated to pay Additional Amounts with respect to such
payment, the Issuer or the Guarantors will deliver to the Trustee an Officer's
Certificate stating the fact that such Additional Amounts will be payable and
the amounts so payable and will set forth such other information necessary to
enable the Trustee to pay such Additional Amounts to Holders on the payment
date. Whenever in this Indenture there is mentioned, in any context, the payment
of principal (and premium, if any), Redemption Price, interest or any other
amount payable under or with respect to any Security, such mention shall be
deemed to include mention of the payment of Additional Amounts to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof.

                  SECTION 10.10. Limitation on Restricted Payments. The Parent
Guarantor (i) may not, and will not permit any Restricted Subsidiary, directly
or indirectly, to declare or pay any dividend, or make any distribution, in
respect of its Capital Stock or to the holders thereof, excluding (x) any
dividends or distributions payable solely in shares of its Capital Stock (other
than Disqualified Stock) or in options, warrants or other rights to acquire its
Capital Stock (other than Disqualified Stock), (y) any dividends paid to the
Parent Guarantor or a Restricted Subsidiary, or (z) pro rata dividends paid on
shares of Common Stock of Restricted Subsidiaries, (ii) may not, and may not
permit any Restricted Subsidiary to, purchase, redeem, or otherwise retire or
acquire for value (a) any Capital Stock of the Parent Guarantor or any Related
Person of the Parent Guarantor (other than a permitted refinancing) or (b) any
options, warrants or rights to purchase or acquire shares of Capital Stock of
the Parent Guarantor or any Related Person of the Parent Guarantor or any
securities convertible or exchangeable into shares of Capital Stock of the
Parent Guarantor or any Related Person of the Parent Guarantor (other than a
permitted refinancing), (iii) may not make, or


                                      -106-

permit any Restricted Subsidiary to make, any Investment, except for Permitted
Investments, and (iv) may not, and may not permit any Restricted Subsidiary to,
redeem, defease, repurchase, retire or otherwise acquire or retire for value,
prior to any scheduled maturity, repayment or sinking fund payment, Debt of the
Guarantors or the Issuer which is subordinate in right of payment to the
Securities or the Securities Guarantee (each of clauses (i) through (iv) being a
"Restricted Payment") if: (1) an Event of Default, or an event that with the
passing of time or the giving of notice, or both, would constitute an Event of
Default, shall have occurred and be continuing, or (2) except with respect to
Investments, upon giving effect to such Restricted Payment, the Parent Guarantor
could not Incur at least $1.00 of additional Debt pursuant to the first
paragraph of Section 10.08, or (3) upon giving effect to such Restricted
Payment, the aggregate of all Restricted Payments from the date hereof exceeds
the sum of: (a)(x) Consolidated Cash Flow Available for Fixed Charges since the
end of the last full fiscal quarter prior to the date hereof through the last
day of the last full fiscal quarter ending immediately preceding the date of
such Restricted Payment (the "Calculation Period") minus (y) 1.5 times
Consolidated Interest Expense for the Calculation Period plus (b) an amount
equal to the net reduction in Investments (other than reductions in Permitted
Investments) in any Person resulting from payments of interest on Debt,
dividends, repayments of loans or advances, or other transfers of assets, in
each case to the Parent Guarantor or any Restricted Subsidiary or from the Net
Cash Proceeds from the sale of any such Investment (except, in each case, to the
extent any such payment or proceeds are included in the calculation of
Consolidated Cash Flow Available for Fixed Charges for the Calculation Period),
or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries
(valued in each case as provided in the definition of Investment), not to
exceed, in each case, the amount of Investments previously made by the Parent
Guarantor or any Restricted Subsidiary in such Person or Unrestricted Subsidiary
plus (c) an amount equal to the aggregate net proceeds received after the date
hereof, including the fair market value of property other than cash (determined
in good faith by the Board of Directors as evidenced by a resolution of the
Board of Directors filed with the Trustee), as capital contributions to the
Parent Guarantor or from the issuance (other than to a Subsidiary) of Capital
Stock (other than Disqualified Stock) of the Parent Guarantor and warrants,
rights or options on Capital Stock (other than Disqualified Stock) of the Parent
Guarantor and the principal amount at maturity of Debt of Parent Guarantor or
any Restricted Subsidiary that


                                      -107-

<PAGE>



has been converted into Capital Stock (other than Disqualified Stock and other
than by a Subsidiary) of the Parent Guarantor after the date hereof plus (d) $30
million.

                  Notwithstanding the foregoing, (i) the Parent Guarantor may
pay any dividend on Capital Stock of any class of the Parent Guarantor within 60
days after the declaration thereof if, on the date when the dividend was
declared, the Parent Guarantor could have paid such dividend in accordance with
the foregoing provisions, (ii) the Parent Guarantor may make acquisitions of a
minority equity interest in entities engaged in the Telecommunications Business;
provided that (A) the acquisition of a majority equity interest in such entities
is not then permitted or practicable under applicable law without regulatory
consent or change of law, (B) the Board of Directors of the Parent Guarantor
determines in good faith that there is a substantial probability that such
approval or change of law will be obtained, (C) the Parent Guarantor or one of
its Restricted Subsidiaries has the right to acquire Capital Stock representing
a majority of the voting power of the Voting Stock of such entity upon receipt
of regulatory consent or change of law and does acquire such Voting Stock
reasonably promptly upon receipt of such consent or change of law and (D) in the
event that such consent or change of law has not been obtained within 18 months
of funding such Investment, the Parent Guarantor or one of its Restricted
Subsidiaries has the right to sell such minority equity interest to the Person
from whom it acquired such interest, for consideration consisting of the
consideration originally paid by the Parent Guarantor and its Restricted
Subsidiaries for such minority equity interest; (iii) the Parent Guarantor may
repurchase any shares of its Common Stock or options to acquire its Common Stock
from Persons who were formerly directors, officers or employees of the Parent
Guarantor or any of its Subsidiaries, provided that the aggregate amount of all
such repurchases made pursuant to this clause (iii) shall not exceed $6 million,
plus the aggregate cash proceeds received by the Parent Guarantor since the date
hereof from issuances of its Common Stock or options to acquire its Common Stock
to directors, officers and employees of the Parent Guarantor or any of its
Subsidiaries, (iv) the Parent Guarantor or a Restricted Subsidiary may redeem,
defease, repurchase, retire or otherwise acquire or retire for value Debt of the
Guarantors or the Issuer which is subordinated in right of payment to the
Securities or the Security Guarantees, as the case may be, in exchange for, or
out of the proceeds of a substantially concurrent sale (other than to a
Subsidiary) of, Capital Stock (other than Disqualified Stock of the


                                      -108-

<PAGE>



Parent Guarantor) or in a refinancing that satisfies the requirements of clause
(iii) of the second paragraph of Section 10.08, (v) the Parent Guarantor and its
Restricted Subsidiaries may retire or repurchase any Capital Stock of the Parent
Guarantor or of any Subsidiary of the Parent Guarantor in exchange for, or out
of the proceeds of the substantially concurrent sale (other than to a Subsidiary
of the Parent Guarantor) of, Capital Stock (other than Disqualified Stock) of
the Parent Guarantor or such Restricted Subsidiary and (vi) the Parent Guarantor
or a Restricted Subsidiary may make payments or distributions to dissenting
stockholders pursuant to applicable law or pursuant to or in connection with a
transaction governed by the provisions of Article VIII hereof, provided that the
number of shares as to which dissent or appraisal rights are exercised and such
payments or distributions are being made does not exceed 1% of the total number
of shares of all classes for which such rights are exercisable.

                  SECTION 10.11. Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries. The Parent Guarantor may not,
and may not permit any Restricted Subsidiary to, directly or indirectly, create
or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction on the ability of any Restricted Subsidiary of the
Parent Guarantor (i) to pay dividends (in cash or otherwise) or make any other
distributions in respect of its Capital Stock owned by the Parent Guarantor or
any other Restricted Subsidiary of the Parent Guarantor or pay any Debt or other
obligation owed to the Parent Guarantor or any other Restricted Subsidiary; (ii)
to make loans or advances to the Parent Guarantor or any other Restricted
Subsidiary; or (iii) to transfer any of its property or assets to the Parent
Guarantor or any other Restricted Subsidiary.

                  Notwithstanding the foregoing, the Parent Guarantor may, and
may permit any Restricted Subsidiary to, suffer to exist any such encumbrance or
restriction (a) pursuant to any agreement in effect on the date hereof; (b)
pursuant to an agreement relating to any Acquired Debt, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person so acquired and was not Incurred in anticipation
of such Person being acquired; (c) pursuant to an agreement effecting a renewal,
refunding or extension of Debt Incurred pursuant to an agreement referred to in
clause (a) or (b) above; provided, however, that the provisions contained in
such renewal, refunding or extension agreement relating to such encumbrance or
restriction are no


                                      -109-

<PAGE>



more restrictive in any material respect than the provisions contained in the
agreement the subject thereof; (d) in the case of clause (iii) in the above
paragraph, contained in any security agreement (including a Capital Lease
Obligation) securing Debt of the Parent Guarantor or a Restricted Subsidiary
otherwise permitted hereunder, but only to the extent such restrictions restrict
the transfer of the property subject to such security agreement; (e) in the case
of clause (iii) in the above paragraph, with respect to customary nonassignment
provisions entered into in the ordinary course of business in leases and other
agreements; (f) with respect to a Restricted Subsidiary of the Parent Guarantor
imposed pursuant to an agreement which has been entered into for the sale or
disposition of all or substantially all of the Capital Stock or assets of such
Restricted Subsidiary, provided that (x) the consummation of such transaction
would not result in an Event of Default or an event that, with the passing of
time or the giving of notice or both, would constitute an Event of Default, (y)
such restriction terminates if such transaction is not consummated and (z) the
consummation or abandonment of such transaction occurs within one year of the
date such agreement was entered into; (g) pursuant to applicable law or required
by any regulatory authority having jurisdiction over the Parent Guarantor or any
Subsidiary; (h) pursuant to this Indenture and the Securities; (i) constituting
a Lien otherwise permitted pursuant to Section 10.15; and (j) other encumbrances
or restrictions that are not materially more restrictive than customary
provisions in comparable financings provided that each of the Issuer and the
Guarantors provides an Officer's Certificate to the Trustee to the effect that
in the opinion of the signers of such certificate such encumbrances or
restrictions will not materially impact the Issuer's and the Guarantors' ability
to make scheduled payments of interest and principal under the Securities.

                  SECTION 10.12. Limitation on Transactions with Affiliates and
Related Persons. The Parent Guarantor 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
Related Person or with any Affiliate of the Parent Guarantor or any Restricted
Subsidiary, except upon fair and reasonable terms no less favorable to the
Parent Guarantor 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


                                      -110-

<PAGE>



providing therefor, in a comparable arm's-length transaction with a Person that
is not a Related Person 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 Parent Guarantor or a Restricted
Subsidiary delivers to the Trustee a written opinion of a nationally recognized
investment banking firm (or a subsidiary or affiliate thereof) in the United
States stating that the transaction is fair to the Parent Guarantor or such
Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Parent Guarantor and any of its Wholly Owned Restricted
Subsidiaries or solely between Wholly Owned Restricted Subsidiaries; and (iii)
any payments or other transactions pursuant to any tax-sharing agreement between
the Parent Guarantor and any other Person with which the Parent Guarantor files
a consolidated tax return or with which the Parent Guarantor is part of a
consolidated group for tax purposes. Notwithstanding the foregoing, any
transaction covered by the first paragraph of this Section and not covered by
clauses (ii) through (iii) of this paragraph must be approved or determined to
be fair in the manner provided for in clause (i)(A) or (B) above unless the
aggregate amount of such transaction is less than $5 million in value.

                  SECTION 10.13. Limitation on Asset Dispositions. (a) The
Parent Guarantor may not, and may not permit any Restricted Subsidiary of the
Parent Guarantor to, make any Asset Disposition in one or more related
transactions unless: (i) the Parent Guarantor or the Restricted Subsidiary, as
the case may be, receives consideration for such disposition at least equal to
the fair market value for the assets sold or disposed of as determined by the
Board of Directors in good faith and, in the case of an Asset Disposition in an
amount greater than $5 million, evidenced by a resolution of the Board of
Directors filed with the Trustee; and (ii) at least 75% of the consideration for
such disposition consists of (1) cash or readily marketable cash equivalents or
the assumption of Debt of the Guarantors (other than Debt that is subordinated
to the Securities and the Securities Guarantee) or of a Restricted Subsidiary
and release from all liability on the Debt assumed, or (2) Telecommunications
Assets. However, none of the provisions of Section 10.13 shall apply to the
issuance or sale of capital stock of (x) deltathree.com, (y) RSL Australia or
(z) RSL Spain, in each case, made in compliance with clause (v) of Section
10.15. In the event and to the extent that the Net Available Proceeds received
by the


                                      -111-

<PAGE>



Parent Guarantor or any of its Restricted Subsidiaries from one or more Asset
Dispositions occurring on or after the date hereof in any period of 12
consecutive months exceed 10% of Consolidated Tangible Assets (determined as of
the date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Parent Guarantor and its subsidiaries have
been filed with the Commission), then the Parent Guarantor or the Issuer shall
or shall cause the relevant Restricted Subsidiary to (i) within 12 months after
the date Net Available Proceeds so received exceed 10% of Consolidated Tangible
Assets (A) apply an amount equal to such excess Net Available Proceeds to
permanently repay unsubordinated Debt of the Parent Guarantor or any Restricted
Subsidiary providing a Subsidiary Guarantee pursuant to Section 10.15 or Debt of
any other Restricted Subsidiary, in each case owing to a Person other than the
Parent Guarantor or any of its Restricted Subsidiaries or (B) invest an equal
amount, or the amount not so applied pursuant to clause (A) (or enter into a
definitive agreement committing to so invest within 12 months after the date of
such agreement), in Telecommunications Assets and (ii) apply (no later than the
end of the 12-month period referred to in clause (i)) such excess Net Available
Proceeds (to the extent not applied pursuant to clause (i)) as provided in the
paragraph (b) below. The amount of such excess Net Available Proceeds required
to be applied (or to be committed to be 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".

                  (b) 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 totals at least $10 million, the Issuer shall
repay any Debt of the Parent Guarantor or any Restricted Subsidiary to the
extent the terms of such Debt require repayment prior to an Offer to Purchase
being made hereunder (including by way of an offer to purchase to the holders of
such Debt, if so required). To the extent there are Excess Proceeds after such
repayment (or offer to purchase), the Issuer must commence, not later than the
fifteenth Business Day of such month (or if later, the fifteenth Business Day
after the expiration of any such required offer to purchase), and consummate an
Offer to Purchase from the holders of the Securities on a pro rata basis an
aggregate principal amount of Securities on the relevant Payment Date equal to
the Excess Proceeds on such date not applied or to be applied pursuant to the
first sentence of this paragraph (b), at a purchase price equal to 100% of the
principal


                                      -112-

<PAGE>



amount of the Securities, plus, in each case, accrued interest (if any) to but
excluding the Payment Date and, to the extent required by the terms thereof, any
other Debt of the Parent Guarantor that is pari passu with the Securities at a
price no greater than 100% of the principal amount thereof plus accrued interest
to but excluding the date of purchase (or 100% of the accreted value in the case
of original issue discount Debt). To the extent there are any remaining Excess
Proceeds following the completion of the Offer to Purchase, the Issuer must
repay such other Debt of the Parent Guarantor or Debt of a Restricted Subsidiary
of the Parent Guarantor, to the extent permitted under the terms thereof and, to
the extent there are any remaining Excess Proceeds after such repayment, the
Issuer shall apply such amount to any other use as determined by the Issuer
which is not otherwise prohibited by this Indenture.

                  SECTION 10.15. Limitation on Issuances and Sales of Capital
Stock of Restricted Subsidiaries. The Parent Guarantor may not, and may not
permit any Restricted Subsidiary of the Parent Guarantor to, issue, transfer,
convey, sell or otherwise dispose of any shares of Capital Stock of a Restricted
Subsidiary of the Parent Guarantor or securities convertible or exchangeable
into, or options, warrants, rights or any other interest with respect to,
Capital Stock of a Restricted Subsidiary of the Parent Guarantor to any Person
other than the Parent Guarantor or a Wholly Owned Restricted Subsidiary of the
Parent Guarantor except (i) a sale of all of the Capital Stock of such
Restricted Subsidiary owned by the Parent Guarantor and any Restricted
Subsidiary of the Parent Guarantor that complies with Section 10.13 above to the
extent such Section applies, (ii) if required, the issuance, transfer,
conveyance, sale or other disposition of directors' qualifying shares, (iii)
Disqualified Stock issued in exchange for, or upon conversion of, or the
proceeds of the issuance of which are used to redeem, refinance, replace or
refund shares of Disqualified Stock of such Restricted Subsidiary; provided that
the amounts of the redemption obligations of such Disqualified Stock shall not
exceed the amounts of the redemption obligations of, and such Disqualified Stock
shall have redemption obligations no earlier than those required by, the
Disqualified Stock being exchanged, converted, redeemed, refinanced, replaced or
refunded and (iv) issuances of not more than 59% of the voting stock and equity
interest in a Restricted Subsidiary engaged in the Telecommunications Business
(1) in connection with the acquisition of such Restricted Subsidiary or of
Telecommunications Assets acquired or to be acquired by the Parent Guarantor or
a Restricted Subsidiary or (2) to a


                                      -113-

<PAGE>



Strategic Investor; provided, that the Parent Guarantor complies with Section
10.13 above to the extent such Section applies and (v) issuances or sales of
capital stock of each of deltathree.com, RSL Australia and RSL Spain, including
pursuant to stock option plans or other equity compensation and incentive plans
established for each of their respective employees, directors, and consultants,
so long as immediately after giving effect to such issuances and sales, the
issuer of such capital stock is a Restricted Subsidiary.

                  SECTION 10.15. Limitation on Liens. The Parent Guarantor may
not, and may not permit any Restricted Subsidiary of the Parent Guarantor to,
Incur or suffer to exist any Lien on or with respect to any property or assets
now owned or hereafter acquired to secure any Debt without making, or causing
such Restricted Subsidiary to make, effective provision for securing the
Securities (x) equally and ratably with such Debt as to such property for so
long as such Debt will be so secured or (y) in the event such Debt is Debt of
the Parent Guarantor which is subordinate in right of payment to the Securities,
prior to such Debt as to such property for so long as such Debt will be so
secured.

                  The foregoing restrictions shall not apply to: (i) Liens
existing on the date hereof and securing Debt outstanding on the date hereof;
(ii) Liens securing Debt outstanding or available under all Credit Facilities to
the extent such Debt is permitted under clause (i) of the second paragraph of
Section 10.08; (iii) Liens in favor of the Parent Guarantor or any Restricted
Subsidiary of the Parent Guarantor; (iv) Liens on real or personal property of
the Parent Guarantor or a Restricted Subsidiary of the Parent Guarantor
acquired, constructed or constituting improvements made after the date of
original issuance of the Securities to secure Purchase Money Debt which is
Incurred for the construction, acquisition and improvement of Telecommunications
Assets and is otherwise permitted under this Indenture; provided, however, that
(a) the principal amount of any Debt secured by such a Lien does not exceed 100%
of such purchase price or cost of construction or improvement of the property
subject to such Liens, (b) such Lien attaches to such property prior to, at the
time of or within 180 days after the acquisition, completion of construction or
commencement of operation of such property and (c) such Lien does not extend to
or cover any property other than the specific item of property (or portion
thereof) acquired, constructed or constituting the improvements made with the
proceeds of such Purchase Money Debt; (v) Liens to secure Acquired Debt;
provided, however, that (a) such Lien attaches to the acquired asset prior to


                                      -115-

the time of the acquisition of such asset and (b) such Lien does not extend to
or cover any other asset; (vi) Liens to secure Debt Incurred to extend, renew,
refinance or refund (or successive extensions, renewals, refinancings or
refundings), in whole or in part, Debt secured by any Lien referred to in the
foregoing clauses (i), (ii), (iv) and (v) so long as the principal amount of
Debt so secured is not increased except as otherwise permitted under clause
(iii) of the second paragraph of Section 10.08 and, in the case of Liens to
secure Debt incurred to extend, renew, refinance or refund Debt secured by a
Lien referred to in the foregoing clause (i), (iv) or (v), such Liens do not
extend to any other property; and (vii) Permitted Liens.

                  SECTION 10.16. Limitation on Issuance of Guarantees of Debt by
Restricted Subsidiaries. The Parent Guarantor will not permit any Restricted
Subsidiary, directly or indirectly, to incur any Guarantee of any Debt of the
Guarantors or the Issuer unless such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture providing for a Guarantee by such
Subsidiary of the Securities; any Subsidiary Guarantee by such Subsidiary of the
Securities (x) will be senior in right of payment to any Guarantee of
Subordinated Debt of the Guarantors or the Issuer and (y) will be pari passu
with or senior to any Guarantee of any other Debt of the Guarantors or the
Issuer.

                  Notwithstanding the foregoing, any Subsidiary Guarantee 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 Parent Guarantor, of all of the Parent Guarantor'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 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 10.17. Change of Control. (a) Unless the Issuer has
heretofore exercised its right to redeem all of the Securities in accordance
with the terms of this Indenture and the Securities, upon the occurrence of a
Change of Control (as defined below), each Holder of a Security shall have the
right to have such Security repurchased by the Issuer on the terms and
conditions precedent set forth in this Section 10.17 and otherwise in this
Indenture. The Issuer shall, within 30 days following


                                      -115-

<PAGE>



the date of the consummation of a transaction resulting in a Change of Control,
mail an Offer with respect to an Offer to Purchase all Outstanding Securities at
a purchase price equal to 101% of their principal amount plus accrued interest
to but excluding the date of purchase. Installments of interest (including
Special Interest) whose Stated Maturity is on or prior to the Purchase Date
shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.07. Each Holder
shall be entitled to tender all or any portion of the Securities owned by such
Holder pursuant to the Offer to Purchase, subject to the requirement that any
portion of a Security tendered must be tendered in an integral multiple of
(U)1,000 principal amount at maturity.

                  (b) The Issuer and Trustee shall perform their respective
obligations specified in the Offer for the Offer to Purchase. Prior to the
Purchase Date, the Issuer shall (i) accept for payment Securities or portions
thereof tendered pursuant to the Offer, (ii) deposit with the Paying Agent (or,
if the Issuer is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) money sufficient to pay the purchase price of all
Securities or portions thereof so accepted and (iii) deliver or cause to be
delivered to the Trustee all Securities so accepted together with an Officers'
Certificate stating the Securities or portions thereof accepted for payment by
the Issuer. The Paying Agent shall promptly mail or deliver to Holders of
Securities so accepted payment in an amount equal to the purchase price, and the
Trustee shall promptly authenticate and mail or deliver to such Holders a new
Security or Securities equal in principal amount to any unpurchased portion of
the Security surrendered as requested by the Holder. Any Security not accepted
for payment shall be promptly mailed or delivered by the Issuer to the Holder
thereof.

                  (c) A "Change of Control" shall be deemed to have occurred in
the event that, after the date of this Indenture, either (i) a "person" or
"group" (within the meaning of Sections 13(d) and 15(d)(2) of the Exchange Act)
becomes the ultimate "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act) of more than 35% of the total voting power of the Voting Stock of
the Parent Guarantor, on a fully diluted basis, and such ownership is greater
than the amount of voting power of the Voting Stock of the Parent Guarantor, on
a fully diluted basis, held by the Existing Stockholders and their Affiliates on
such date;


                                      -116-

<PAGE>



(ii) individuals who on the date of this Indenture constitute the Board of
Directors (together with any new directors whose election by the Board of
Directors or whose nomination for election by the Parent Guarantor's
stockholders was approved by a vote of at least two-thirds of the members of the
Board of Directors then in office who either were members of the Board of
Directors on the date of this Indenture or whose election or nomination for
election was previously so approved) cease for any reason to constitute a
majority of the members of the Board of Directors then in office; or (iii) all
of the Common Stock of the Issuer is not beneficially owned by the Parent
Guarantor (other than directors' qualifying shares).

                  (d) In the event that the Issuer makes an Offer to Purchase
the Securities, the Issuer and the Guarantors shall comply with any applicable
securities laws and regulations, including any applicable requirements of
Section 15(e) of, and Rule 15e-1 under, the Securities Exchange Act.

                  SECTION 10.18. Provision of Financial Information. The
Guarantors and the Issuer have agreed that, for so long as any Securities remain
Outstanding, each will furnish to the holders of the Securities and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 155A(d)(5) under the
Securities Act. In addition, the Guarantors and the Issuer will file with the
Trustee within 15 days after it files them with the Commission copies of the
annual and quarterly reports and the information, documents, and other reports
that the Guarantors or the Issuer is required to file with the Commission
pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC Reports"). In the
event either Guarantor or the Issuer shall cease to be required to file SEC
Reports pursuant to the Exchange Act, such Guarantor and the Issuer will
nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing) and the Trustee. The Guarantors and
the Issuer will furnish copies of the SEC Reports to the holders of Securities
at the time the Guarantors or the Issuer is required to file the same with the
Trustee and will make such information available to investors who request it in
writing.

                  SECTION 10.19. Statement by Officers as to Default. (a) The
Issuer and the Guarantors will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Parent Guarantor ending after the date hereof,


                                      -117-

<PAGE>



an Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof either Guarantor or the Issuer is in default in the performance
and observance of any of the terms, provisions and conditions of Sections 10.05
to 10.18, inclusive, and if either Guarantor or the Issuer shall be in default,
specifying all such defaults and the nature and status thereof of which they may
have knowledge.

                  (b) The Issuer and the Guarantors shall deliver to the
Trustee, as soon as possible and in any event within 10 days after the Issuer or
either Guarantor becomes aware of the occurrence of an 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 Issuer or such Guarantor proposes to
take with respect thereto.

                  SECTION 10.20. Waiver of Certain Covenants. The Issuer, the
Parent Guarantor or the Subsidiary Guarantor, as applicable, may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 10.05 to 10.17, inclusive, if before or after the time for such
compliance the Holders of at least a majority in aggregate principal amount at
maturity of the Outstanding Securities shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Issuer and the Guarantors
and the duties of the Trustee in respect of any such covenant or condition shall
remain in full force and effect.

                  SECTION 10.21. Paying Agent. The Issuer shall not authorize or
designate any Person (including the Trustee) as a Paying Agent hereunder unless
such Person is located outside of the United Kingdom.


                                   ARTICLE XI

                            Redemption of Securities

                  SECTION 11.01. Right of Redemption. (a) At any time prior to
March 1, 2003, in the event that the Parent Guarantor receives net cash proceeds
from the public or private sale of its Common Stock (other than Disqualified
Stock), the Issuer (to the extent it receives such proceeds


                                      -118-

<PAGE>



and has not used such proceeds, directly or indirectly, to redeem or repurchase
other securities pursuant to optional redemption provisions) may, at its option,
apply an amount equal to any such net cash proceeds to redeem, from time to
time, Securities in a principal amount at maturity of up to an aggregate amount
equal to 33 1/3% of the original aggregate principal amount at maturity of the
Securities; provided, however, that Securities in an amount equal to at least 66
2/3% of the original aggregate principal amount at maturity of the Securities
remain Outstanding after each redemption. Each redemption must occur on a
Redemption Date within 180 days of the related sale and upon not less than 30
nor more than 60 days' notice by mail to each Holder of Securities to be
redeemed at such Holder's address appearing in the Security Register, in amounts
of (U)1,000 or an integral multiple of (U)1,000 at a Redemption Price of
112.875% of the principal amount of the Securities plus accrued interest to but
excluding the Redemption Date (subject to, in the case of a Global Security in
bearer form, the right of the Holder thereof and, in the case of Definitive
Securities, the right of Holders of record on the relevant Regular Record Date,
to receive Interest due on an Interest Payment Date that is on or prior to the
Redemption Date).

                  (b) In the event that (i) the Guarantors or the Issuer has
become or would become obligated to pay any Additional Amounts as a result of
(x) changes affecting withholding tax laws or (y) a Listing Failure (as defined
herein) provided that the Issuer has used reasonable best efforts to list and
maintain the listing of the Securities on a "recognized stock exchange" (within
the meaning of Section 851 of the U.K. Income and Corporation Taxes Act 1988)
(as provided for in Section 10.09), and (ii) the Guarantors and the Issuer are
unable to avoid the requirement to pay such Additional Amounts by taking
reasonable measures available to them (including, without limitation, the
Guarantors making payments directly to holders under the Securities Guarantee,
unless such payment is likely to result in adverse consequences to the Issuer or
either Guarantor), then the Issuer may redeem all, but not less than all, of the
Securities at any time at 100% of the principal amount thereof on the Redemption
Date, together with accrued interest thereon, if any, to but excluding the
Redemption Date (subject to, in the case of a Global Security in bearer form,
the right of the Holder thereof and, in the case of Definitive Securities, the
right of Holders of record on the relevant Regular Record Date, to receive
Interest due on an Interest Payment Date that is on or prior to the Redemption
Date). Prior to the publication


                                      -119-

<PAGE>



of the notice of redemption in accordance with the foregoing, the Issuer shall
deliver to the Trustee an officer's certificate stating that the Issuer is
entitled to effect such redemption based on a written opinion of independent tax
counsel or accounting firm reasonably satisfactory to the Trustee.

                  (c) The Securities further may be redeemed, as a whole or in
part, at the election of the Issuer, at any time on or after March 1, 2005 and
prior to maturity, upon not less than 30 nor more than 60 days' notice by mail
to each Holder of Securities to be redeemed at such Holder's address appearing
in the Security Register, in amounts of (U)1,000 or an integral multiple of
(U)1,000, at the Redemption Prices specified in the form of Security
hereinbefore set forth, together with accrued interest to but excluding the
Redemption Date (subject to, in the case of a Global Security in bearer form,
the right of the Holder thereof and, in the case of Definitive Securities, the
right of Holders of record on the relevant Regular Record Date, to receive
Interest due on an Interest Payment Date that is on or prior to the Redemption
Date).

                  SECTION 11.02. Applicability of Article. Redemption of
Securities at the election of the Issuer, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and
this Article.

                  SECTION 11.03. Election To Redeem; Notice to Trustee. The
election of the Issuer to redeem any Securities pursuant to Section 11.01 shall
be evidenced by a Board Resolution. In case of any redemption at the election of
the Issuer of less than all the Securities, the Issuer shall, at least 5 days
prior to giving notice of such redemption pursuant to Section 11.05 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date and of the principal amount of Securities to be
redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Issuer shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

                  SECTION 11.05. Securities To Be Redeemed Pro Rata. If less
than all the Securities are to be redeemed in any redemption, the Securities to
be redeemed shall be selected by the Trustee by prorating, as nearly as may be
practicable, the principal amount at maturity of Securities


                                      -120-

<PAGE>



to be redeemed. In any proration pursuant to this Section, the Trustee shall
make such adjustments, reallocations and eliminations as it shall deem proper to
the end that the principal amount at maturity of Securities so prorated shall be
(U)1,000 or a multiple thereof, by increasing or decreasing or eliminating the
amount which would be allocable to any Holder on the basis of exact proportion
by an amount not exceeding (U)1,000. The Trustee in its discretion may determine
the particular Securities (if there are more than one) registered in the name of
any Holder which are to be redeemed, in whole or in part. The Trustee shall
incur no liabilities for any selection made pursuant to this Section 11.05.

                  The Trustee shall promptly notify the Issuer and each Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount at
maturity thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal amount at maturity of such Securities
which has been or is to be redeemed.

                  SECTION 11.05. Notice of Redemption. Notice of redemption
shall be given by first-class mail, postage prepaid, mailed not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Securities to
be redeemed, at such Holder's address appearing in the Security Register.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (3) whether the redemption is being made pursuant to Section
         11.01(a), (b) or (c) and, if being made pursuant to Section 11.01(a) or
         (b), a brief statement setting forth the Issuer's right to effect such
         redemption and the Issuer's basis therefor,

                  (5) if less than all the Outstanding Securities are to be
         redeemed, the identification (and, in the case of partial redemption of
         any Securities, the


                                      -121-

<PAGE>



         principal amounts at maturity) of the particular Securities to be
         redeemed,

                  (5) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and that
         interest thereon will cease to accrue on and after said date,

                  (6) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

                  (7) that in the case that a Security is only redeemed in part,
         the Issuer shall execute and the Trustee shall authenticate and deliver
         to the Holder of such Security without service charge, a new Security
         or Securities in an aggregate amount equal to the unredeemed portion of
         the Security.

                  Notice of redemption of Securities to be redeemed at the
election of the Issuer shall be given by the Issuer or, at the Issuer's request,
by the Trustee in the name and at the expense of the Issuer. If so requested by
the Issuer, the Trustee shall mail any such notice not later than the date
specified for mailing by the Issuer, which shall not be sooner than 5 days after
receipt by the Trustee of such request (unless a shorter period shall be
satisfactory to the Trustee).

                  SECTION 11.06. Deposit of Redemption Price. Prior to any
Redemption Date, the Issuer shall deposit with the Trustee or with a Paying
Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 10.03) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed
on that date.

                  SECTION 11.07. Securities Payable on Redemption Date. Notice
of redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Issuer shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Issuer at the
Redemption Price, together with accrued interest to but excluding the


                                      -122-

<PAGE>



Redemption Date; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the bearer of
such Security, in the case of a Global Security in bearer form, and, in the case
of a Definitive Security, to Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
3.07.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium, if any)
shall, until paid, bear interest from the Redemption Date at the rate provided
by the Security.

                  SECTION 11.08. Securities Redeemed in Part. Any Security which
is to be redeemed only in part shall be surrendered at an office or agency of
the Issuer designated for that purpose pursuant to Section 10.02 (with, if the
Issuer or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Issuer
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of like
tenor, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

                  (a) all Securities previously authenticated and delivered
         (other than destroyed, lost or stolen Securities that have been
         replaced or Securities for whose payment money or securities have
         theretofore been held in trust and thereafter repaid to the Issuer, as
         provided in Section 12.05) have been delivered to the Trustee for
         cancelation and the Issuer has paid all sums payable by it hereunder;
         or

                  (b)(i) all such Securities 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, (ii)
         the Issuer irrevocably deposits in trust with the Trustee during such
         one-year period, under the terms of an irrevocable trust agreement in
         form satisfactory to the Trustee, as trust funds solely for the benefit
         of the Holders of such Securities for that purpose, money or U.S.
         Government Obligations sufficient (in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee), without
         consideration of any reinvestment of any interest thereon, to pay
         principal, premium, if any, and interest on such Securities to maturity
         or redemption, as the case may be, and to pay all other sums payable by
         it hereunder, (iii) no Default or Event of Default with respect to the
         Securities shall have occurred and be continuing on the date of such

         or constitute a default under, this Indenture or any other agreement or
         instrument to which the Parent Guarantor or the Issuer is a party or by
         which it is bound, (v) if at such time the Securities are listed on a
         national securities exchange, the Securities will not be delisted as a

         has delivered to the Trustee an Officers' Certificate and an Opinion of
         Counsel, in each case stating that all conditions precedent provided

Securities have matured or have been redeemed. Thereafter, only the Issuer's
obligations in Sections 6.07, 12.05 and 12.06 shall survive. After any such
irrevocable deposit, the Trustee upon written request shall acknowledge in
writing the discharge of the Issuer's obligations under the Securities and this
Indenture, and the Parent Guarantor's obligations under the Guarantee and this
Indenture, except for those surviving obligations specified above.

                  SECTION 12.02. Defeasance and Discharge of Indenture. The
Issuer will be deemed to have paid and the Issuer and the Guarantors will be
discharged from any and all obligations in respect of the Securities and the
Securities Guarantee on the 123rd day after the date of the deposit referred to

         Trustee and has conveyed all right, title and interest for the benefit
         of the Holders, under the terms of an irrevocable trust agreement in
         form satisfactory to the Trustee as trust funds in trust, specifically
         pledged to the Trustee for the benefit of the Holders as security for
         payment of the principal of, premium, if any, and interest, if any, on
         the Securities, and dedicated solely to, the benefit of the Holders, in
         and to (i) money in an amount, (ii) U.S. Government Obligations that,
         through the payment of interest, premium, if any, and principal in

         than one day before the due date of any payment referred to in this
         clause (a), money in an amount or (iii) a combination thereof in an
         amount sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, without
         consideration of the reinvestment of such interest and after payment of
         all federal, state and local taxes or other charges and assessments in
         respect thereof payable by the Trustee, the principal of, premium, if
         any, and accrued interest on the Outstanding Securities at the Stated
         Maturity of such principal or interest or upon earlier redemption;
         provided that the Trustee shall have been irrevocably instructed to
         apply such money or the proceeds of such U.S. Government Obligations to
         the payment of such principal, premium, if any, and interest with
         respect to the Securities and to give any related notice of redemption;

                  (b) 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 Guarantors, the Issuer or any of their
         Subsidiaries is a party or by which the Guarantors, the Issuer or any
         of their Subsidiaries is bound;

                  (c) immediately after giving effect to such deposit on a pro
         forma basis, no Default or Event of


                                      -125-

<PAGE>



         Default, or event that after the giving of notice or lapse of time or
         both could become a Default or 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;

                  (d) the Issuer shall have delivered to the Trustee either (i)
         a ruling based on relevant law and practice at the time directed to the
         Trustee from the Inland Revenue or other relevant tax authority to the
         effect that the Holders will not recognize income, gain or loss for
         U.K. income tax or other tax purposes as a result of the Issuer's
         exercise of its option under this Section 12.02, disregarding income
         tax on any amounts that would have been received but for such exercise
         of its option under this Section 12.02, and will be subject to U.K.
         income tax on the same amount and in the same manner and at the same
         time as would have been the case if such option had not been exercised
         or (ii) an Opinion of Counsel to the same effect as the ruling
         described in clause (i) above;

                  (e) the Issuer shall have delivered to the Trustee (i) either
         (A) a ruling directed to the Trustee received from the Internal Revenue
         Service to the effect that the Holders will not recognize additional
         income, gain or loss for U.S. federal income tax purposes as a result
         of the Issuer's exercise of its option under this Section 12.02 and
         will be subject to U.S. 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 option had not been exercised or (B) an Opinion of Counsel to the
         same effect as the ruling described in clause (A) above accompanied by
         a ruling to that effect published by the Internal Revenue Service,
         unless there has been a change in the relevant U.S. federal income tax
         law since the date of this Indenture and (ii) an Opinion of Counsel to
         the effect that (A) the creation of the defeasance trust does not
         violate the Investment Company Act of 1950 and (B) after the passage of
         123 days following the deposit (except, with respect to any trust funds
         for the account of any Holder who may be deemed to be "connected" with
         the Issuer for purposes of the Insolvency Act 1986 after two years
         following the deposit), the trust funds will not be subject to the
         effect of Section 557 of the United States Bankruptcy Code or Section
         15 of the New York Debtor and Creditor Law and either (I) the trust
         funds will no longer remain the property of the Issuer (and therefore
         will


                                      -126-

<PAGE>



         not be subject to the effect of any applicable bankruptcy, insolvency,
         reorganization or similar laws affecting creditors' rights generally)
         or (II) if a court were to rule under any such law in any case or
         proceeding that the trust funds remained property of the Issuer (1)
         assuming such trust funds remained in the possession of the Trustee
         prior to such court ruling to the extent not paid to the Holders, the
         Trustee will hold, for the benefit of the Holders, a valid and
         perfected security interest in such trust funds that is not avoidable
         in bankruptcy or otherwise and (2) no property, rights in property or
         other interests granted to the Trustee or the Holders in exchange for,
         or with respect to, such trust funds will be subject to any prior
         rights of holders of other Debt of the Issuer or any of its Securities;

                  (f) if at such time the Securities are listed on a national
         securities exchange, the Issuer shall have delivered to the Trustee an
         Opinion of Counsel to the effect that the Securities will not be
         delisted as a result of the Issuer's exercise of its opinion under this
         Section 12.02; and

                  (g) the Issuer 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 12.02 have been complied with.

                  Notwithstanding the foregoing, prior to the end of the post
deposit period referred to in clause (e)(ii)(B) of this Section 12.02, none of
the Issuer's obligations under this Indenture shall be discharged. Subsequent to
the end of such period with respect to this Section 12.02, the Issuer's
obligations in Sections 3.03, 3.05, 3.05, 3.06, 3.07, 10.01, 10.09, 6.07, 6.10,
6.11, 12.05, 12.05 and 12.06 shall survive until the Securities mature or are
redeemed. Thereafter, only the Issuer's obligations in Sections 6.07, 12.05 and
12.06 shall survive. If and when a ruling from the Internal Revenue Service or
an Opinion of Counsel referred to in clause (e)(i) of this Section 12.02 may be
provided specifically without regard to, and not in reliance upon, the
continuance of the Issuer's obligations under Section 10.01, then the Issuer's
obligations under such sentence 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
12.02.

                  After any such irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of the Issuer's obligations under the
Securities, any Subsidiary Guarantee, if any, and this Indenture except for
those surviving obligations in the immediately preceding paragraph.

                  SECTION 12.03. Defeasance of Certain Obligations. The Issuer
and the Guarantors may omit to comply with any term, provision or condition set

(except for Section 10.09 and any covenant otherwise required by the TIA), and
clause (d) of Section 5.01 with respect to clauses (3) and (5) of Section 8.01,
clauses (d) and (e) of Section 5.01 with respect to Sections 10.05 through
10.18, except as aforesaid, and clauses (c), (f) and (g) of Section 5.01 shall
be deemed not to be Events of Default, in each case with respect to the
Outstanding Securities if:

                  (a) with reference to this Section 12.03, the Issuer has
         irrevocably deposited or caused to be irrevocably deposited with the
         Trustee and conveyed all right, title and interest to the Trustee for
         the benefit of the Holders, under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee as trust
         funds in trust, specifically pledged to the Trustee for the benefit of
         the Holders as security for payment of the principal of, premium, if
         any, and interest, if any, on the Securities, and dedicated solely to,
         the benefit of the Holders, in and to (i) money in an amount, (ii) U.S.
         Government Obligations that, through the payment of interest and
         principal in respect thereof in accordance with their terms, will
         provide, not later than one day before the due date of any payment
         referred to in this clause (a), money in an amount or (iii) a
         combination thereof in an amount sufficient, in the opinion of a
         nationally recognized firm of independent public accountants expressed
         in a written certification thereof delivered to the Trustee, to pay and
         discharge, without consideration of the reinvestment of such interest
         and after payment of all federal, state and local taxes or other
         charges and assessments in respect thereof payable by the Trustee, the
         principal of, premium, if any, and interest on the Outstanding
         Securities on the Stated Maturity or upon earlier redemption of such
         principal or interest; provided that the Trustee shall have been
         irrevocably instructed to apply such money or the proceeds of such U.S.
         Government Obligations to the payment of such


                                      -128-

         principal, premium, if any, and interest with respect to the Securities
         and to give any related notice of redemption;

                  (b) 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 Parent Guarantor, the Issuer or any of their
         Subsidiaries is a party or by which the Parent Guarantor, the Issuer or
         any of their Subsidiaries is bound;

                  (c) immediately after giving effect to such deposit or a pro
         forma basis, no Default or Event of Default, or event that after the
         giving of notice or lapse of time or both would become a Default or
         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 day
         of such deposit;

                  (d) the Issuer has delivered to the Trustee an Opinion of
         Counsel to the effect that (i) the creation of the defeasance trust
         does not violate the Investment Company Act of 1950, (ii) the Holders
         will not recognize income, gain or loss for U.S. federal income tax
         purposes as a result of such deposit and the defeasance of the
         obligations referred to in the first paragraph of this Section 12.03
         and will be subject to U.S. federal income tax on the same amount and

         passage of 123 days following the deposit (except with respect to any
         trust funds for the account of any Holder who may be deemed to be
         "connected" with the Issuer for purposes of the Insolvency Act 1986
         after two years following the deposit), the trust funds will not be
         subject to the effect of Section 557 of the United States Bankruptcy
         Code or Section 15 of the New York Debtor and Creditor Law, and either
         (A) the trust funds will no longer remain the property of the Issuer
         (and therefore will not be subject to the effect of any applicable
         bankruptcy, insolvency, reorganization or similar laws affecting
         creditor's rights generally) or (B) if a court were to rule under any
         such law in any case or proceeding that the trust funds remained
         property of the Issuer (1) assuming such trust funds remained in the
         possession of the Trustee prior to such court ruling to the extent not
         paid to the Holders, the Trustee will hold, for the benefit of the
         Holders, a


                                      -129-

<PAGE>



         valid and perfected security interest in such trust funds that is not
         avoidable in bankruptcy or otherwise and (2) no property, rights in
         property or other interests granted to the Trustee or the Holders in
         exchange for, or with respect to, such trust funds will be subject to
         any prior rights or holders of other Indebtedness of the Issuer or any
         of its Securities;

                  (e) if at such time the Securities are listed on a national
         securities exchange, the Issuer has delivered to the Trustee an Opinion
         of Counsel to the effect that the Securities will not be delisted as a
         result of the Issuer's exercise of its option under Section 12.03; and

                  (f) the Issuer 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 defeasance
         contemplated by this Section 12.03 have been complied with.

                  SECTION 12.05. Application of Trust Money. Subject to Section
12.06, the Trustee or Paying Agent shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to Section 12.01, 12.02 or 12.03, as the
case may be, and shall apply the deposited money and the money from U.S.
Government Obligations in accordance with the Securities and this Indenture to
the payment of principal of, premium, if any, and interest on the Securities;
but such money need not be segregated from other funds except to the extent
required by law.

                  SECTION 12.05. Repayment to Issuer. Subject to Sections 6.07,
12.01, 12.02 and 12.03, the Trustee and the Paying Agent shall promptly pay to
the Issuer upon request set forth in an Officers' Certificate any excess money
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 Issuer
any money held by them for the payment of principal, premium, if any, or
interest that remains unclaimed in accordance with Section 10.02.

                  SECTION 12.06. Reinstatement. If the Trustee or Paying Agent
is unable to apply any money or U.S. Government Obligations in accordance with
Section 12.01, 12.02 or 12.03, 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
obligations of the Issuer


                                      -130-

<PAGE>



and the Guarantors under this Indenture, the Securities Guarantee, and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.01, 12.02 or 12.03, as the case may be, until such time
as the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 12.01, 12.02 or 12.03, as the
case may be; provided that, if the Issuer has made any payment of principal of,
premium, if any, or interest on any Securities because of the reinstatement of
its obligations, the Issuer shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

                  SECTION 12.07. Insiders. With respect to the determination of
the Persons constituting beneficial owners of Securities and whether any such
Person is "connected" with the Issuer for purposes of Sections 12.02(e)(ii)(B)
and 12.03(d)(iii), the Trustee may rely on an Officers' Certificate.

         2. Registration Under the Securities Act.

         (a) Except as set forth in Section 2(b) below, the Issuer agrees to
file under the Securities Act and use its reasonable best efforts to cause to be
declared effective, a registration statement relating to an offer to exchange
any and all of the Dollar Notes and an offer to exchange any and all of the Euro
Notes (such registration statement, the "Exchange Registration Statement", and
such offers, the "Exchange Offers" and each individually, an "Exchange Offer")
for a like aggregate principal dollar or euro amount, as applicable, of debt
securities issued by the Issuer and guaranteed by the Guarantor, which debt
securities and guarantees are substantially identical to the Securities (and are
entitled to the benefits of trust indentures which are substantially identical
to the Indentures or are the Indentures, and which have each been qualified
under the Trust Indenture Act), except that they have been registered pursuant
to an effective registration statement under the Securities Act and do not
contain registration rights, transfer restrictions and provisions for the
additional interest contemplated in Section 2(c) below (such new debt securities
hereinafter called "Exchange Securities"). The Issuer agrees to use its
reasonable best efforts to cause the Exchange Registration Statement to become
effective under the Securities Act and to consummate each Exchange Offer as soon
as practicable, but no later than 210 days after the Closing Date. The Exchange
Offers will be registered under the Securities Act on the appropriate form
required by the Commission and will comply with all applicable tender offer
rules and regulations under the Exchange Act and all applicable federal and
state securities laws. The Issuer further agrees to use its reasonable best
efforts to hold each Exchange Offer open for at least 30 days and issue Exchange
Securities for all Registrable Securities that have been properly tendered and
not withdrawn on or prior to the expiration of each Exchange Offer. Each
Exchange Offer will be deemed to have been "completed" only if the debt
securities and related guarantees received by holders other than Restricted
Holders in the Exchange Offer for Registrable Securities are, upon receipt,
transferable by each such holder without need for


                                                   -5-


<PAGE>

further compliance with Section 5 of the Securities Act (except for the
requirement to deliver a prospectus included in the Exchange Registration
Statement applicable to resales by broker-dealers of Exchange Securities
received by such broker-dealer pursuant to an Exchange Offer in exchange for
Registrable Securities other than those acquired by the broker-dealer directly
from the Issuer) and without material restrictions under the blue sky or
securities laws of a substantial majority of the States of the United States of
America. Each Exchange Offer shall be deemed to have been completed upon the
earlier to occur of (i) the Issuer having exchanged the Exchange Securities for
all outstanding Registrable Securities pursuant to such Exchange Offer and (ii)
the Issuer having exchanged, pursuant to such Exchange Offer, Exchange
Securities for all Registrable Securities that have been properly tendered and
not withdrawn before the expiration of such Exchange Offer, which shall be on a
date that is at least 30 days following the commencement of the Exchange Offer.
The Issuer agrees (x) to include in the Exchange Registration Statement a
prospectus for use in connection with any resales of Exchange Securities by a
broker-dealer, other than resales of Exchange Securities received by a
broker-dealer pursuant to an Exchange Offer in exchange for Registrable
Securities acquired by the broker-dealer directly from the Issuer, and (y) to
keep such Exchange Registration Statement effective for a period (the "Resale
Period") beginning when Exchange Securities are first issued in the Exchange
Offers and ending upon the earlier of (x) the expiration of the 90th day after
the Exchange Offers have been completed and (y) such time as such broker-dealers
no longer own any Registrable Securities. With respect to such Exchange
Registration Statement, each broker-dealer that holds Exchange Securities
received in an Exchange Offer in exchange for Registerable Securities not
acquired by it directly from the Issuer shall have the benefit of the rights of
indemnification and contribution set forth in Sections 6(a), (c), (d) and (e)
hereof.

         (b) If prior to the time the Exchange Offers are completed existing
Commission interpretations are changed such that the debt securities or any
related guarantees received by holders other than Restricted Holders in the
Exchange Offers for Registrable Securities are not or would not be, upon
receipt, transferable by each such holder without need for further compliance
with Section 5 of the Securities Act (except for the requirement to deliver a
prospectus included in the Exchange Registration Statement applicable to resales
by broker-dealers of Exchange Securities received by such broker-dealer pursuant
to an Exchange Offer in exchange for Registrable Securities other than those
acquired by the broker-dealer directly from the Issuer) in lieu of conducting
the Exchange Offers contemplated by Section 2(a), the Issuer shall file under
the Securities Act and use its reasonable best efforts to cause to be declared
effective a "shelf" registration statement providing for the registration of,
and the sale on a continuous or delayed basis by the holders of, all of the
Registrable Securities, pursuant to Rule 515 or any similar rule that may be
adopted by the Commission (such filing, the "Shelf Registration" and such
registration statement, the "Shelf Registration Statement"), provided, however,
if the Issuer determines that it is advisable to disclose in the Shelf
Registration Statement a financing, acquisition or other corporate transaction,
and the Board of Directors of the Issuer shall have determined in good faith
that such disclosure would not be in the best interests of the Issuer and its
stockholders, the Issuer shall not be required to prepare and file such
amendment, supplement or document for such period or periods as the Board of
Directors of the Issuer shall have determined in good faith is in the best
interests of the Issuer and shall be entitled to suspend the availability of the
Shelf Registration Statement, provided further, however that such period or
periods of suspension shall not exceed 90 days in the aggregate in any
consecutive 365-day period. In addition, in the event that the Purchasers shall
not have resold all of the Securities initially purchased by them from the
Issuer pursuant to the Purchase Agreement, prior to the consummation of the
Exchange Offers, the Issuer shall file under the Securities Act as soon as
practicable a Shelf

                                                   -5-


<PAGE>

Registration Statement, which if permitted by the Commission may be by way of a
post-effective amendment to the Exchange Registration Statement. The Issuer
agrees to use its best efforts to cause the Shelf Registration Statement to
become or be declared effective no later than 210 days after the Closing Date
and to keep such Shelf Registration Statement continuously effective for a
period ending on the earlier of (x) the second anniversary of the Closing Date
and (y) such time as there are no longer any Registrable Securities outstanding.
The Issuer further agrees to supplement or make amendments to the Shelf
Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Issuer for such
Shelf Registration Statement or by the Securities Act or rules and regulations
promulgated thereunder for a shelf registration, and the Issuer agrees to
furnish to the holders of the Registrable Securities copies of any such
supplement or amendment to such registration statement prior to its being used
or promptly following its filing with the Commission. Attached as Exhibit A
hereto is a form of Notice of Registration Statement and Selling Securityholder
Questionnaire to be completed by holders in connection with a Shelf Registration
of the Dollar Notes pursuant to this Section 2(b).

         (c) In the event that (i) either Exchange Offer has not been completed,
or a Shelf Registration Statement has not been declared effective, within 210
days after the Closing Date or (ii) any Exchange Registration Statement or Shelf
Registration Statement required by Section 2(a) or 2(b) hereof is filed and
declared effective but shall thereafter, prior to the time such Exchange
Registration Statement or Shelf Registration Statement is no longer required to
be effective pursuant to Section 2(a) or 2(b) hereof, as the case may be, either
be withdrawn by the Issuer or shall become subject to an effective stop order
issued pursuant to Section 8(d) of the Securities Act suspending the
effectiveness of such registration statement (except as specifically permitted
herein) without being succeeded immediately by an additional registration
statement filed and declared effective (each such event referred to in clauses
(i) and (ii), a "Registration Default" and each period during which a
Registration Default has occurred and is continuing, a "Registration Default
Period"), then, as liquidated damages for such Registration Default, subject to
the provisions of Section 9(b), special interest ("Special Interest"), in
addition to the Base Interest, shall accrue at a per annum rate of 0.50% for the
Registration Default Period. The Special Interest shall be payable in cash
semi-annually in arrears on each March 1 and September 1. Special Interest, if
any, shall be computed on the basis of a 360 day year of twelve 30-day months
and the number of days actually elapsed.

         (d) The Issuer and the Guarantor shall take all actions reasonably
necessary or advisable to be taken by them to ensure that the transactions
contemplated herein are effected as so contemplated.

         (e) Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be
incorporated, therein by reference as of such time and any reference herein to
any post-effective amendment to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time.

         3. Registration Procedures.

         (a) (i) In connection with the Exchange Offers, the Issuer shall comply
with all of the provisions of Section 3(d) and Section 3(e) below, shall use its
reasonable best efforts to effect such exchanges to permit the sale of
Registrable Securities being sold in accordance with the intended method or
methods of distribution thereof, and, prior to effectiveness of the Exchange
Offer Registration Statement, shall, if required by the

                                                   -6-

Commission, provide a supplemental letter to the Commission (A) stating that the
Issuer is registering the Exchange Offers in reliance on the position of the
Commission enunciated in Exxon Capital Holdings Corporation (available May 13,
1988) and Morgan Stanley and Co., Inc. (available June 5, 1991) and (B)
including a representation that the Issuer has not entered into any arrangement
or understanding with any person to distribute the Exchange Securities to be
received in the Exchange Offers and that, to the best of the Issuer's
information and belief, each holder participating in the Exchange Offers is
acquiring the Exchange Securities in its ordinary course of business and has no
arrangement or understanding with any person to participate in the distribution
of the Exchange Securities received in the Exchange Offers.

                  (ii) As a condition to its participation in either Exchange
Offer pursuant to the terms of this Agreement, each holder of Registrable
Securities shall furnish, upon the request of the Issuer, prior to the
consummation thereof, a written representation to the Issuer (which may be
contained in the letter of transmittal contemplated by the Exchange Offer
Registration Statement) to the effect that (A) it is not an affiliate of the
Issuer or the Guarantor, (B) it is not engaged in, and does not intend to engage
in, and has no arrangement or understanding with any person to participate in, a
distribution of the Exchange Securities to be issued in either Exchange Offer
and (C) it is acquiring the Exchange Securities in its ordinary course of
business. In addition, all such holders of Registrable Securities shall
otherwise cooperate in the Issuer's and the Guarantor's preparations for the
Exchange Offers. Each holder hereby acknowledges and agrees that any
broker-dealer and any such holder, in either case, exchanging Registrable
Securities in either Exchange Offer, in connection with the resale of Exchange
Securities acquired in such Exchange Offer, (1) could not under Commission
policy as in effect on the date of this Agreement rely on the position of the
Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991)
and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted
in the Commission's letter to Shearman & Sterling dated July 2, 1993, and
similar no-action letters, and (2) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction and that such a secondary resale transaction should
be covered by an effective registration statement containing the selling
security holder information required by Item 507 or 508, as applicable, of
Regulation S-K if the resales are of Exchange Securities obtained by such holder
in exchange for Registrable Securities acquired by such holder directly from the
Issuer.

         If the Issuer files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

         (b) At or before the Effective Time of the Exchange Offers or the Shelf
Registration, as the case may be, the Issuer shall qualify the Indentures under
the Trust Indenture Act.

         (c) In the event that such qualification would require the appointment
of a new trustee under either or both of the Indentures, the Issuer shall
appoint a new trustee thereunder pursuant to the applicable provisions of such
Indenture or Indentures.

         (d) In connection with the Issuer's obligations with respect to the
registration of Exchange Securities as contemplated by Section 2(a) (the
"Exchange Registration"), if applicable, the Issuer shall, as soon as reasonably
possible (or as otherwise specified):

                  (i) prepare and file with the Commission an Exchange
         Registration Statement on any form which may be utilized by the Issuer
         and which shall permit

                                       -7-


<PAGE>




the Exchange Offer and resales of Exchange Securities by broker-dealers during
the Resale Period to be effected as contemplated by Section 2(a), and use its
reasonable best efforts to cause such Exchange Registration Statement to become
effective and to consummate the Exchange Offer, as soon as practicable
thereafter, but no later than 210 days after the Closing Date;

         (ii) as soon as practicable prepare and file with the Commission such
amendments and supplements to such Exchange Registration Statement and the
prospectus included therein as may be necessary to effect and maintain the
effectiveness of such Exchange Registration Statement for the periods and
purposes contemplated in Section 2(a) hereof and as may be required by the
applicable rules and regulations of the Commission and the instructions
applicable to the form of such Exchange Registration Statement, and promptly
provide each broker-dealer holding Exchange Securities with such number of
copies of the prospectus included therein (as then amended or supplemented), in
conformity in all material respects with the requirements of the Securities Act
and the Trust Indenture Act and the rules and regulations of the Commission
thereunder, as such broker-dealer reasonably may request prior to the expiration
of the Resale Period, for use in connection with resales of Exchange Securities;

         (iii) promptly notify the Purchasers and their counsel and, with
respect to clause C, E and F below only, any broker-dealer that has advised the
Issuer or the Guarantor that it is entitled to a resale prospectus during the
Resale Period, and confirm such advice in writing, (A) when such Exchange
Registration Statement or the prospectus included therein or any prospectus
amendment or supplement or post-effective amendment has been filed, and, with
respect to such Exchange Registration Statement or any post-effective amendment,
when the same has become effective, (B) of any comments by the Commission and by
the Blue Sky or securities commissioner or regulator of any state with respect
thereto or any request by the Commission for amendments or supplements to such
Exchange Registration Statement or prospectus or for additional information, (C)
of the issuance by the Commission of any stop order suspending the effectiveness
of such Exchange Registration Statement or the initiation or threatening of any
proceedings for that purpose, (D) if at any time the representations and
warranties of the Issuer and the Guarantor contemplated by Section 5 hereof
cease to be true and correct in all material respects, (E) of the receipt by the
Issuer or the Guarantor of any notification with respect to the suspension of
the qualification of the Exchange Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose or (F) at any time
during the Resale Period when a prospectus is required to be delivered under the
Securities Act, that such Exchange Registration Statement, prospectus,
prospectus amendment or supplement or post-effective amendment thereto does not
conform in all material respects to the applicable requirements of the
Securities Act and the Trust Indenture Act and the rules and regulations of the
Commission thereunder or contains an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing;

         (iv) in the event that the Issuer would be required, pursuant to
Section 3(d)(iii)(F) above, to notify any broker-dealer entitled to a resale
prospectus during the Resale Period, prepare and furnish without delay to each
such holder a reasonable number of copies of a prospectus supplemented or
amended so that, as thereafter delivered to purchasers of such Exchange
Securities

                                       -8-


<PAGE>




         during the Resale Period, such prospectus shall conform in all material
         respects to the applicable requirements of the Securities Act and the
         Trust Indenture Act and the rules and regulations of the Commission
         thereunder and shall 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 in light of the
         circumstances then existing;

                  (v) use its reasonable best efforts to obtain the withdrawal
         of any order suspending the effectiveness of such Exchange Registration
         Statement or any post-effective amendment thereto at the earliest
         practicable date;

                  (vi) use its reasonable best efforts to (A) register or
         qualify the Exchange Securities under the securities laws or blue sky
         laws of such jurisdictions in the United States as are contemplated by
         Section 2(a) no later than the commencement of the Exchange Offers, (B)
         keep such registrations or qualifications in effect and comply with
         such laws so as to permit the continuance of offers, sales and dealings
         therein in such jurisdictions until the expiration of the Resale Period
         and (C) take any and all other actions as may be reasonably necessary
         or advisable to enable each broker-dealer holding Exchange Securities
         to consummate the disposition thereof in such jurisdictions; provided,
         however, that neither the Issuer nor the Guarantor shall be required
         for any such purpose to (1) qualify as a foreign corporation in any
         jurisdiction wherein it would not otherwise be required to qualify but
         for the requirements of this Section 3(d)(vi), (2) consent to general
         service of process in any such jurisdiction, (3) become subject to any

         approval of each governmental agency or authority, whether federal,

         Registration, the Exchange Offers and the offering and sale of Exchange

any, thereof, as applicable, the Issuer shall without delay prepare and furnish
to each such holder, to each placement or sales agent, if any, and to each such
underwriter, if any, a reasonable number of copies of a prospectus supplemented
or amended so that, as thereafter delivered to purchasers of Registrable
Securities, such prospectus shall conform in all material respects to the
applicable requirements of the Securities Act and the Trust Indenture Act and
the rules and regulations of the Commission thereunder and shall 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 in

agrees that upon receipt of any notice from the Issuer pursuant to Section
3(e)(vi)(F) hereof, such holder shall forthwith discontinue the disposition of
Registrable Securities pursuant to the Shelf Registration Statement applicable
to such Registrable Securities until such holder shall have received copies of
such amended or supplemented prospectus, and if so directed by the Issuer, such
holder shall deliver to the Issuer, (at the Issuer's expense) all copies, other

which any Shelf Registration pursuant to Section 2(b) is being effected to
furnish to the Issuer such information regarding such holder and such holder's
intended method of distribution of such Registrable Securities as the Issuer may
from time to time reasonably request in writing, but only to the extent that
such information is required in order to comply with the Securities Act. Each
such holder agrees to notify the Issuer as promptly as practicable of any
inaccuracy or change in information previously furnished by such holder to the
Issuer or of the occurrence of any event in either case as a result of which any
prospectus relating to such Shelf Registration contains or would contain an
untrue statement of a material fact regarding such holder or such holder's
intended method of disposition of such Registrable Securities or omits to state
any material fact regarding such holder or such holder's intended method of
disposition of such Registrable Securities required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing, and promptly to furnish to the Issuer any
additional information required to correct and update any previously furnished
information or required so that such prospectus shall not contain, with respect
to such holder or the disposition of such Registrable Securities, 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 in
light of the circumstances then existing.

         (h) Until the expiration of two years after the Closing Date, the
Issuer will not, and will not permit any of its "affiliates" (as defined in Rule
155) to, resell any of the Securities that have been reacquired by any of them
except pursuant to an effective registration statement under the Securities Act.

the Issuer's and the Guarantor's officers and employees performing legal or

5. Representations and Warranties.

         The Issuer and the Guarantor, jointly and severally, represents and
warrants to, and agrees with, the Purchasers and each of the holders from time
to time of Registrable Securities that:

                  (a) Each registration statement covering Registrable
         Securities and each prospectus (including any preliminary or summary
         prospectus) contained therein or furnished pursuant to Section 3(e) or
         Section 3(d) hereof and any further amendments or supplements to any
         such registration statement or prospectus, when it becomes effective or
         is filed with the Commission, as the case may be, and, in the case of
         an underwritten offering of Registrable Securities, at the time of the
         closing under the underwriting agreement relating thereto, will conform
         in all material respects to the applicable requirements of the
         Securities Act and the Trust Indenture Act and the rules and
         regulations of the Commission thereunder and 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 at all times subsequent to the Effective Time when a
         prospectus would be required to be delivered under the Securities Act,
         other than from (i) such time as a notice has been given to holders of
         Registrable Securities pursuant to Section 3(e)(vi)(F) or Section
         3(d)(iii)(F) hereof until (ii) such time as the Issuer furnishes an
         amended or supplemented prospectus pursuant to Section 3(f) or Section
         3(d)(iv) hereof, each such registration statement, and each prospectus
         (including any summary prospectus) contained therein or furnished
         pursuant to Section 3(e) or Section 3(d) hereof, as then amended or
         supplemented, will conform in all material respects to the applicable
         requirements of the Securities Act and the Trust Indenture Act and the
         rules and regulations of the Commission thereunder and will not contain
         an untrue statement of a material fact


                                      -17-


<PAGE>

         or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading in the light of
         the circumstances then existing; provided, however, that this
         representation and warranty shall not apply to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Issuer by or on behalf of a holder of
         Registrable Securities expressly for use therein.

                  (b) Any documents incorporated by reference in any prospectus
         referred to in Section 5(a) hereof, when they become or became
         effective or are or were filed with the Commission, as the case may be,
         will conform or conformed in all material respects to the requirements
         of the Securities Act or the Exchange Act, as applicable, and none of
         such documents will contain or contained an untrue statement of a
         material fact or will omit or omitted to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading; provided, however, that this representation and warranty
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished in writing to the Issuer
         by or on behalf of a holder of Registrable Securities expressly for use
         therein.

                  (c) The compliance by the Issuer and the Guarantor with all of
         the provisions of this Exchange and Registration Rights Agreement and
         the consummation of the transactions herein contemplated will not (i)
         result in any violation of the provisions of the Memorandum and
         Articles of Association of the Issuer, the Memorandum of Association or
         Bye-laws of the Guarantor, (ii) result in a breach or violation of any
         of the terms or provisions of, or constitute a default under, any
         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument to which the Issuer or the Guarantor or any of their
         subsidiaries is a party or by which the Issuer or the Guarantor or any
         of their subsidiaries is bound or to which any of the property or
         assets of the Issuer or the Guarantor or any of their subsidiaries is
         subject, nor (iii) will such action result in any violation of any
         existing statute, order, rule or regulation of any court or
         governmental agency or body having jurisdiction over the Issuer, the
         Guarantor or any of their subsidiaries or any of their properties
         except, in the case of clauses (ii) and (iii) above, such breaches or
         violations which would not, individually or in the aggregate, be
         reasonably likely to have a material adverse change, in or affecting
         the general affairs, management, financial position, shareholders'
         equity or results of operations of the Issuer, the Guarantor and their
         subsidiaries taken as a whole; and no consent, approval, authorization,
         order, registration or qualification of or with any such governmental
         agency is required for the issue and sale of the Securities or the
         consummation by the Issuer or the Guarantor of the transactions
         contemplated by this Registration Rights Agreement, except the
         registration under the Securities Act of the Securities, qualification
         of the Indenture, under the Trust Indenture Act and such consents,
         approvals, authorizations, registrations or qualifications as may be
         required under State or foreign securities or blue sky laws in
         connection with the offering and distribution of the Securities.

                  (d) This Exchange and Registration Rights Agreement has been
         duly authorized, executed and delivered by the Issuer and the
         Guarantor.

         6. Indemnification.

         (a) Indemnification by the Issuer and the Guarantor. The Issuer and the
Guarantor, jointly and severally, will indemnify and hold harmless each of the
holders of

                                      -18-


<PAGE>



Registrable Securities included in a registration statement filed pursuant to
Section 2(a) or 2(b) hereof, and each person who participates as a placement or
sales agent or as an underwriter in any offering or sale of such Registrable
Securities against any losses, claims, damages or liabilities, joint or several,
to which such holder, agent or underwriter may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registrable Securities were registered
under the Securities Act, or any preliminary, final or summary prospectus
contained therein or furnished by the Issuer or the Guarantor to any such
holder, agent or underwriter, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, and will
reimburse such holder, such agent and such underwriter for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
however, that the Issuer and the Guarantor shall not be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement, or preliminary, final or
summary prospectus, or amendment or supplement thereto, in reliance upon and in
conformity with written information furnished to the Issuer or the Guarantor by
or on behalf of holders of Registrable Securities expressly for use therein;

         (b) Indemnification by the Holders and any Agents and Underwriters. The
Issuer may require, as a condition to including any Registrable Securities in
any registration statement filed pursuant to Section 2(b) hereof and to entering
into any underwriting agreement with respect thereto, that the Issuer shall have
received an undertaking reasonably satisfactory to it from the holder of such
Registrable Securities and from each underwriter named in any such underwriting
agreement, severally and not jointly, to (i) indemnify and hold harmless the
Issuer and the Guarantor, and all other holders of Registrable Securities,
against any losses, claims, damages or liabilities to which the Issuer or the
Guarantor or such other holders of Registrable Securities may become subject,
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, or any preliminary, final or summary prospectus
contained therein or furnished by the Issuer to any such holder, agent or
underwriter, or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished to the
Issuer or the Guarantor by or on behalf of such holder or underwriter expressly
for use therein, and (ii) reimburse the Issuer or the Guarantor for any legal or
other expenses reasonably incurred by the Issuer or the Guarantor in connection
with investigating or defending any such action or claim as such expenses are
incurred; provided, however, that no such holder shall be required to undertake
liability to any person under this Section 6(b) for any amounts in excess of the
dollar amount of the proceeds to be received by such holder from the sale of
such holder's Registrable Securities pursuant to such registration.

         (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be
made against an

                                      -19-


<PAGE>



indemnifying party pursuant to the indemnification provisions of or contemplated
by this Section 6, notify such indemnifying party in writing of the commencement
of such action; but the omission so to notify the indemnifying party shall not
relieve it from any liability which it may have to any indemnified party other
than under the indemnification provisions of or contemplated by Section 6(a) or
6(b) hereof. In case any such action shall be brought against any indemnified
party and it shall notify an indemnifying party of the commencement thereof, and
such indemnifying party shall be entitled to participate therein and, to the
extent that it shall wish, jointly with any other indemnifying party similarly
noti fied, to assume the defense thereof, with counsel reasonably satisfactory
to such indemnified party (who shall not, except with the consent of the
indemnified party, be counsel to the indemnifying party), and, after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, such indemnifying party shall not be liable to such
indemnified party for any legal expenses of other counsel or any other expenses,
in each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (d) Contribution. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 6(d) were determined by
pro rata allocation (even if the holders or any agents or underwriters or all of
them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 6(d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any
amount in excess

                                      -20-


<PAGE>

of the amount by which the dollar amount of the proceeds received by such holder
from the sale of any Registrable Securities (after deducting any fees, discounts
and commissions applicable thereto) exceeds the amount of any damages which such
holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission, and no underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such underwriter 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 holders' and any underwriters'
obligations in this Section 6(d) to contribute shall be several in proportion to
the principal amount of Registrable Securities registered or underwritten, as
the case may be, by them and not joint.

         (e) The obligations of the Issuer and the Guarantor under this Section
6 shall be in addition to any liability which the Issuer or the Guarantor may
otherwise have and shall extend, upon the same terms and conditions, to each
officer, director and partner of each holder, agent and underwriter and each
person, if any, who controls any holder, agent or underwriter within the meaning
of the Securities Act; and the obligations of the holders and any agents or
underwriters contemplated by this Section 6 shall be in addition to any
liability which the respective holder, agent or underwriter may otherwise have
and shall extend, upon the same terms and conditions, to each officer and
director of the Issuer and the Guarantor (including any person who, with his
consent, is named in any registration statement as about to become a director of
the Issuer or the Guarantor) and to each person, if any, who controls the Issuer
or the Guarantor within the meaning of the Securities Act.

         7. Underwritten Offerings.

         (a) Selection of Underwriters. If any of the Registrable Securities
covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be designated
by the holders of at least a majority in aggregate principal amount of the
Registrable Securities to be included in such offering, provided that such
designated managing underwriter or underwriters is or are reasonably acceptable
to the Issuer.

         (b) Participation by Holders. Each holder of Registrable Securities
hereby agrees with each other such holder that no such holder may participate in
any underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         8. Rule 155.

         Each of the Issuer and the Guarantor covenants to the holders of
Registrable Securities that to the extent it shall be required to do so under
the Exchange Act, it shall timely file the reports required to be filed by it
under the Exchange Act or the Securities Act (including the reports under
Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of
Rule 155 adopted by the Commission under the Securities Act) and the rules and
regulations adopted by the Commission thereunder, and shall take such further
action as any holder of Registrable Securities may reasonably request, all to
the extent required from time to time to enable such holder to sell Registrable
Securities without registration under the Securities Act within the limitations
of the exemption provided by Rule 155 under the Securities Act, as such Rule may
be amended from time to time, or any similar or successor rule or regulation
hereafter adopted by the Commis-

                                      -21-


<PAGE>

sion. Upon the request of any holder of Registrable Securities in connection
with that holder's sale pursuant to Rule 155, the Issuer or the Guarantor, as
applicable, shall deliver to such holder a written statement as to whether it
has complied with such requirements.

         9. Miscellaneous.

         (a) No Inconsistent Agreements. The Issuer represents, warrants,
covenants and agrees that it has not granted, and shall not grant, registration
rights with respect to Registrable Securities or any other securities which
would be inconsistent with the terms contained in this Exchange and Registration
Rights Agreement.

         (b) Specific Performance. The parties hereto acknowledge that there
would be no adequate remedy at law if any party fails to perform any of their
respective obligations hereunder and that each party may be irreparably harmed
by any such failure, and accordingly agree that each party, in addition to any
other remedy to which they may be entitled at law or in equity, shall be
entitled to compel specific performance of the respective obligations of any
other party under this Exchange and Registration Rights Agreement in accordance
with the terms and conditions of this Exchange and Registration Rights
Agreement, in any court of the United States or any State thereof having
jurisdiction.

         (c) Notices. All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally or by courier, or
three days after being deposited in the mail (registered or certified mail,
postage prepaid, return receipt requested) as follows: If to the Issuer or the
Guarantor, to it at 767 Fifth Avenue, Suite 5300, New York, New York 10153, c/o

address as the Issuer or any such holder may have furnished to the other in
writing in accordance herewith, except that notices of change of address shall
be effective only upon receipt.

         (d) Parties in Interest. All the terms and provisions of this Exchange
and Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders from
time to time of the Registrable Securities and the respective successors and
assigns of the parties hereto and such holders. In the event that any transferee
of any holder of Registrable Securities shall acquire Registrable Securities, in
any manner, whether by gift, bequest, purchase, operation of law or otherwise,
such transferee shall, without any further writing or action of any kind, be
deemed a beneficiary hereof for all purposes and such Registrable Securities
shall be held subject to all of the terms of this Exchange and Registration
Rights Agreement, and by taking and holding such Registrable Securities such
transferee shall be entitled to receive the benefits of, and be conclusively
deemed to have agreed to be bound by, all of the applicable terms and provisions
of this Exchange and Registration Rights Agreement. If the Issuer shall so
request, any such successor, assign or transferee shall acknowledge in writing
that such successor, assign, or transferee will acquire and hold the Registrable
Securities subject to all of the applicable terms hereof.

         (e) Survival. The respective indemnities, agreements, representations,
warranties and each other provision set forth in this Exchange and Registration
Rights Agreement or made pursuant hereto shall remain in full force and effect
regardless of any investigation

                                      -22-


<PAGE>

(or statement as to the results thereof) made by or on behalf of the Purchasers
or any holder of Registrable Securities, any director, officer or partner of
such holder, any agent or underwriter or any director, officer or partner
thereof, or any controlling person of any of the foregoing, and shall survive
delivery of and payment for the Registrable Securities pursuant to the Purchase
Agreement and the transfer and registration of Registrable Securities by such
holder and the consummation of each Exchange Offer.

         (f) LAW GOVERNING. THIS EXCHANGE AND REGISTRATION RIGHTS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAW OF THE STATE OF NEW YORK.

         (g) Headings. The descriptive headings of the several Sections and
paragraphs of this Exchange and Registration Rights Agreement are inserted for
convenience only, do not constitute a part of this Exchange and Registration
Rights Agreement and shall not affect in any way the meaning or interpretation
of this Exchange and Registration Rights Agreement.

         (h) Entire Agreement; Amendments. This Exchange and Registration Rights
Agreement and the other writings referred to herein (including the Indentures
and the form of Securities) or delivered pursuant hereto which form a part
hereof contain the entire understanding of the parties with respect to its
subject matter. This Exchange and Registration Rights Agreement supersedes all
prior agreements and understandings between the parties with respect to its
subject matter. This Exchange and Registration Rights Agreement may be amended
and the observance of any term of this Exchange and Registration Rights
Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively) only by a written instrument duly executed by
the Issuer and the holders of at least a majority in aggregate principal amount
of the Registrable Securities at the time outstanding. Each holder of any
Registrable Securities at the time or thereafter outstanding shall be bound by
any amendment or waiver effected pursuant to this Section 9(h), whether or not
any notice, writing or marking indicating such amendment or waiver appears on
such Registrable Securities or is delivered to such holder. Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of holders whose Registrable Securities are
being tendered pursuant to the Exchange Offer and that does not affect directly
or indirectly the rights of other holders whose Registrable Securities are not
being tendered pursuant to such Exchange Offer may be given by the holders of at
least a majority of the outstanding principal amount of Registrable Securities
being tendered or registered.

         (i) Inspection. For so long as this Exchange and Registration Rights
Agreement shall be in effect, this Exchange and Registration Rights Agreement
and a complete list of the names and addresses of all the holders of Registrable
Securities shall be made available for inspection and copying on any business
day by any holder of Registrable Securities for proper purposes only (which
shall include any purpose related to the rights of the holders of Registrable
Securities under the Securities, the Indentures and this Agreement) at the
offices of the Issuer at the address thereof set forth in Section 9(c) above and
at the office of the Trustee under the Indentures.

         (j) Counterparts. This agreement may be executed by the parties in
counterparts, each of which shall be deemed to be an original, but all such
respective counterparts shall together constitute one and the same instrument.

                  WHEREAS, the Issuer, the Guarantor and the Trustee entered
into the Indenture pursuant to which the Issuer issued its 10 1/2% Senior Notes
due 2008 (the "Securities");

irrevocably guaranteeing, on an unsubordinated basis, all of the obligations of

                  WHEREAS, Section 10.16 of the Indenture provides that the

Securities on the terms provided herein;



<PAGE>

                  WHEREAS, the Boards of Directors of the Issuer, the Guarantor
and the Subsidiary Guarantor have authorized the execution of the Second
Supplemental Indenture and its delivery to the Trustee;

                  WHEREAS, the Company and the Guarantor have delivered an
Opinion of Counsel to the Trustee pursuant to Section 9.03 of the Indenture;

                  WHEREAS, all other actions necessary to make this Second

and the Trustee desire to enter into, execute and deliver this Second
Supplemental Indenture in compliance with the provisions of the Indenture.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee
hereby agree as follows for the benefit of each other and for the equal and
ratable benefit of the Holders of the Notes:

                                   ARTICLE I
                              SUBSIDIARY GUARANTEE

                  SECTION 1.01. Guarantee. Subject to the provisions of this
Article One, the Subsidiary Guarantor hereby fully, unconditionally and
irrevocably guarantees to each Holder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
on and interest (including Special Interest) on each Security, when and as the
same shall become due and payable, whether at maturity, by acceleration or
otherwise, the due and punctual payment of interest on the overdue principal of
and interest, if any, on the Securities, to the extent lawful, and the due and
punctual performance of all other obligations of the Issuer to the Holders or
the Trustee, all in accordance with the terms of such Security and this
Indenture and (ii) in the case of any extension of time of payment or renewal of
any Securities or any of such other obligations, that the same will be promptly
paid in full when due or performed in accordance with the terms of the extension
or renewal, at Stated Maturity, by acceleration or otherwise. The Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger or bankruptcy of the Issuer, any
right to require a proceeding first against the Issuer, the benefit of
discussion, protest or notice with respect to any such Security or the debt
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged as to any such Security except by payment in full of the
principal thereof and interest thereon and as provided in Section 12.01 and
Section 12.02 (subject to Section 12.06) of the Indenture. The maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five of
the Indenture for the purposes of this Article One. In the

                                        2

<PAGE>

event of any declaration of acceleration of such obligations as provided in
Article Five of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Article One. In addition, without limiting the foregoing
provisions, upon the effectiveness of an acceleration under Article Five of the
Indenture, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article One.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or the Subsidiary Guarantor, or
any custodian, receiver, liquidator, trustee, sequestrator or other similar
official acting in relation to the Issuer, the Guarantor or the Subsidiary
Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Subsidiary Guarantor further agrees, to
the fullest extent that the Subsidiary Guarantor may lawfully do so, that, as
between the Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

<PAGE>

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Security unless the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 1.02. Obligations Unconditional. Subject to Section
1.05, nothing contained in this Article One or elsewhere in the Indenture or in
the Securities is intended to or shall impair, as among the Subsidiary Guarantor
and the holders of the Securities, the obligation of the Subsidiary Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the
holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
holders of the Securities and creditors of the Subsidiary Guarantor, nor shall
anything herein or therein prevent the holder of any Securities or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor
shall give prompt written notice to the Trustee of any fact known to the
Subsidiary Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee pursuant to the provisions of this Article
One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                  SECTION 2.01. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Second Supplemental Indenture or the Securities, and it shall not be
responsible for any statement of the Issuer or the Guarantor or the Subsidiary
Guarantor in this Second Supplemental Indenture.

amended, the Indenture and the Securities issued thereunder are in all respects
ratified and confirmed and all the terms, conditions and provisions thereof
shall remain in full force and effect. Upon execution, this Second Supplemental
Indenture shall form a part of the Indenture and the Second Supplemental
Indenture and the Indenture shall be read, taken and construed as one and the
same instrument for all purposes, and every holder of Securities heretofore or
hereafter authenticated and delivered under the Indenture shall be bound hereby.

                  SECTION 2.03. Effectiveness. This Second Supplemental
Indenture shall become effective as of the date first above written.

                  SECTION 2.05. Governing Law. THIS SECOND SUPPLEMENTAL

STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE

number of copies of this Second Supplemental Indenture. Each signed copy shall
be an original, but all of them together represent the same agreement. One
signed copy is enough to prove this Second Supplemental Indenture.

including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

                  The Guarantee set forth in this Section 1.01 shall not be or

behalf of the Trustee.

                  SECTION 1.02. Obligations Unconditional. Subject to Section
1.05, nothing contained in this Article One or elsewhere in the Indenture or in

and the holders of the Securities, the obligation of the Subsidiary Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the

anything herein or therein prevent the holder of any Securities or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable

prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor
shall give prompt written notice to the Trustee of any fact known to the
Subsidiary Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee pursuant to the provisions of this Article
One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                          SECOND SUPPLEMENTAL INDENTURE

                  SECOND SUPPLEMENTAL INDENTURE, dated as of February 22, 2000
(the "Second Supplemental Indenture"), between RSL Communications PLC, a United
Kingdom corporation, as issuer (hereinafter called the "Issuer"), RSL

the "Guarantor"), RSL COM U.S.A., Inc., a Delaware corporation, as guarantor
(hereinafter called the "Subsidiary Guarantor"), and The Chase Manhattan Bank, a
corporation duly organized and existing under the laws of the State of New York,
as Trustee (hereinafter called the "Trustee").

                  Capitalized terms used herein but not otherwise defined herein
shall have the meanings given to such terms in the Indenture, dated as of
October 3, 1996, between the Company, the Guarantor and the Trustee (the
"Indenture").

                                    Recitals

                  WHEREAS, the Issuer, the Guarantor and the Trustee entered
into the Indenture pursuant to which the Issuer issued its 12 1/5% Senior Notes
due 2006 (the "Notes");

                  WHEREAS, the Issuer desires to issue its euro denominated
senior notes due 2010 (the "Euro Notes") and its dollar denominated senior notes
due 2010 (the "Dollar Notes") in an aggregate principal amount of up to

                  WHEREAS, the Subsidiary Guarantor has substantially benefited
from the issuance of the Notes and expects to substantially benefit from the
issuance of the Dollar Notes and the Euro Notes;

                  WHEREAS, to facilitate the offering of the Dollar Notes and
the Euro Notes, the Subsidiary Guarantor is fully, unconditionally and
irrevocably guaranteeing, on an unsubordinated basis, all of the obligations of
the Issuer under the Dollar Notes, the Euro Notes and the indentures pursuant to
which they will be issued;

                  WHEREAS, Section 5.07 of the Indenture provides that the
Subsidiary Guarantor may not guarantee any Indebtedness of the Issuer unless the
Subsidiary Guarantor simultaneously executes and delivers a supplemental
indenture to the Indenture providing for a guarantee of payment of the Notes on
the terms provided herein;


<PAGE>


                  WHEREAS, the Boards of Directors of the Issuer, the Guarantor
and the Subsidiary Guarantor have authorized the execution of the Second
Supplemental Indenture and its delivery to the Trustee;

                  WHEREAS, the Company and the Guarantor have delivered an
Opinion of Counsel to the Trustee pursuant to Section 9.05 of the Indenture;

                  WHEREAS, all other actions necessary to make this Second
Supplemental Indenture a legal, valid and binding obligation of the parties
hereto in accordance with its terms and the terms of the Indenture have been
performed; and

                  WHEREAS, the Issuer, the Guarantor, the Subsidiary Guarantor
and the Trustee desire to enter into, execute and deliver this Second
Supplemental Indenture in compliance with the provisions of the Indenture.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee
hereby agree as follows for the benefit of each other and for the equal and
ratable benefit of the Holders of the Notes:

                                   Article I
                              SUBSIDIARY GUARANTEE

                  SECTION 1.01. Guarantee. Subject to the provisions of this
Article One, the Subsidiary Guarantor hereby fully, unconditionally and
irrevocably guarantees to each Holder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
on and interest (including Special Interest) on each Note, when and as the same
shall become due and payable, whether at maturity, by acceleration or otherwise,
the due and punctual payment of interest on the overdue principal of and
interest, if any, on the Notes, to the extent lawful, and the due and punctual
performance of all other obligations of the Issuer to the Holders or the
Trustee, all in accordance with the terms of such Note and this Indenture and
(ii) in the case of any extension of time of payment or renewal of any Notes or
any of such other obligations, that the same will be promptly paid in full when
due or performed in accordance with the terms of the extension or renewal, at
Stated Maturity, by acceleration or otherwise. The Subsidiary Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of merger or bankruptcy of the Issuer, any right to require a
proceeding first against the Issuer, the benefit of discussion, protest or
notice with respect to any such Note or the debt evidenced thereby and all
demands whatsoever, and covenants that this Guarantee will not be discharged as
to any such Note except by payment in full of the principal thereof and interest
thereon and as provided in Section 8.01 and Section 8.02 (subject to Section
8.06) of the Indenture. The maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six of the Indenture for the purposes of this
Article One. In the event of any declaration of

                                       2

<PAGE>

acceleration of such obligations as provided in Article Six of the Indenture,
such obligations (whether or not due and payable) shall forthwith become due and
payable by the Subsidiary Guarantor for the purpose of this Article One. In
addition, without limiting the foregoing provisions, upon the effectiveness of
an acceleration under Article Six of the Indenture, the Trustee shall promptly
make a demand for payment on the Notes under the Guarantee provided for in this
Article One.

                  If the Trustee or the Holder of any Note is required by any
court or otherwise to return to the Issuer or the Subsidiary Guarantor, or any
custodian, receiver, liquidator, trustee, sequestrator or other similar official
acting in relation to the Issuer, the Guarantor or the Subsidiary Guarantor, any
amount paid to the Trustee or such Holder in respect of a Note, this Guarantee,
to the extent theretofore discharged, shall be reinstated in full force and
effect. The Subsidiary Guarantor further agrees, to the fullest extent that the
Subsidiary Guarantor may lawfully do so, that, as between the Subsidiary
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand,
the maturity of the obligations guaranteed hereby may be accelerated as provided
in Article Six of the Indenture for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition extant under any
applicable bankruptcy law preventing such acceleration in respect of the
obligations guaranteed hereby.

                  Until such time as the Notes are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Note on account
of such claim or other rights. If any amount shall be paid to the Subsidiary
Guarantor in violation of the preceding sentence and the principal of, premium,
if any, and accrued interest on the Notes shall not have been paid in full, such
amount shall be deemed to have been paid to the Subsidiary Guarantor for the
benefit of, and held in trust for the benefit of, the Holders, and shall
forthwith be paid to the Trustee for the benefit of the Holders to be credited
and applied upon the principal of, premium, if any, and accrued interest on the
Notes. The Subsidiary Guarantor acknowledges that the Subsidiary Guarantor has
received and will receive direct and indirect benefits from the issuance of the
Notes pursuant to the Indenture and that the waivers set forth in this Section
1.01 are knowingly made in contemplation of such benefits.

                                       3

<PAGE>

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Note unless the
certificate of authentication on such Note shall have been signed by or on
behalf of the Trustee.

                  SECTION 1.02. Obligations Unconditional. Subject to Section
1.05, nothing contained in this Article One or elsewhere in the Indenture or in
the Notes is intended to or shall impair, as among the Subsidiary Guarantor and
the holders of the Notes, the obligation of the Subsidiary Guarantor, which is
absolute and unconditional, upon failure by the Issuer, to pay to the holders of
the Notes the principal of, premium, if any, and interest on the Notes as and
when the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the holders of the Notes and
creditors of the Subsidiary Guarantor, nor shall anything herein or therein
prevent the holder of any Notes or the Trustee on their behalf from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the Notes
to take any action to declare the Guarantee to be due and payable prior to the
Stated Maturity of the Notes pursuant to Section 6.02 of the Indenture or to
pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor
shall give prompt written notice to the Trustee of any fact known to the
Subsidiary Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee pursuant to the provisions of this Article
One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Notes or placement of the Notes on
creditwatch with negative implications.

                                   Article II
                                  MISCELLANEOUS

                  SECTION 2.01. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of

Supplemental Indenture or the Notes, and it shall not be responsible for any
statement of the Issuer or the Guarantor or the Subsidiary Guarantor in this
Second Supplemental Indenture.

                  SECTION 2.02. Ratification. Except as hereby expressly
amended, the Indenture and the Notes issued thereunder are in all respects
ratified and confirmed and all the terms, conditions and provisions thereof
shall remain in full force and effect. Upon execution, this Second Supplemental
Indenture shall form a part of the Indenture and the Second Supplemental
Indenture and the Indenture shall be read, taken and construed as one and the
same instrument for all purposes, and every holder of Notes heretofore or
hereafter authenticated and delivered under the Indenture shall be bound hereby.

                  SECTION 2.03. Effectiveness. This Second Supplemental
Indenture shall become effective as of the date first above written.

                  SECTION 2.05. Governing Law. THIS SECOND SUPPLEMENTAL
INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE

number of copies of this Second Supplemental Indenture. Each signed copy shall
be an original, but all of them together represent the same agreement. One
signed copy is enough to prove this Second Supplemental Indenture.

                  SECOND SUPPLEMENTAL INDENTURE, dated as of February 22, 2000

(hereinafter called the "Subsidiary Guarantor"), and The Chase Manhattan Bank, a

                  Capitalized terms used herein but not otherwise defined herein
shall have the meanings given to such terms in the Indenture, dated as of
November 9, 1998, between the Company, the Guarantor and the Trustee (the
"Indenture").

                                    Recitals

                  WHEREAS, the Issuer, the Guarantor and the Trustee entered
into the Indenture pursuant to which the Issuer issued its 12% Senior Notes due
2008 (the "Securities");

                  WHEREAS, the Issuer desires to issue its euro denominated
senior notes due 2010 (the "Euro Notes") and its dollar denominated senior notes
due 2010 (the "Dollar Notes") in an aggregate principal amount of up to
approximately $230,000,000 (or the U.S. dollar equivalent);

                  WHEREAS, the Subsidiary Guarantor has substantially benefited
from the issuance of the Notes and expects to substantially benefit from the
issuance of the Dollar Notes and the Euro Notes;

                  WHEREAS, to facilitate the offering of the Dollar Notes and
the Euro Notes, the Subsidiary Guarantor is fully, unconditionally and
irrevocably guaranteeing, on an unsubordinated basis, all of the obligations of
the Issuer under the Dollar Notes, the Euro Notes and the indentures pursuant to
which they will be issued;

                  WHEREAS, Section 10.16 of the Indenture provides that the
Subsidiary Guarantor may not guarantee any Indebtedness of the Issuer unless the
Subsidiary Guarantor simultaneously executes and delivers a supplemental
indenture to the Indenture providing for a guarantee of payment of the
Securities on the terms provided herein;


<PAGE>

                  WHEREAS, the Boards of Directors of the Issuer, the Guarantor
and the Subsidiary Guarantor have authorized the execution of the Second
Supplemental Indenture and its delivery to the Trustee;

                  WHEREAS, the Company and the Guarantor have delivered an
Opinion of Counsel to the Trustee pursuant to Section 9.03 of the Indenture;

                  WHEREAS, all other actions necessary to make this Second
Supplemental Indenture a legal, valid and binding obligation of the parties
hereto in accordance with its terms and the terms of the Indenture have been
performed; and

                  WHEREAS, the Issuer, the Guarantor, the Subsidiary Guarantor
and the Trustee desire to enter into, execute and deliver this Second
Supplemental Indenture in compliance with the provisions of the Indenture.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee
hereby agree as follows for the benefit of each other and for the equal and
ratable benefit of the Holders of the Notes:

                                   Article I
                              SUBSIDIARY GUARANTEE

                  SECTION 1.01. Guarantee. Subject to the provisions of this
Article One, the Subsidiary Guarantor hereby fully, unconditionally and
irrevocably guarantees to each Holder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
on and interest (including Special Interest) on each Security, when and as the
same shall become due and payable, whether at maturity, by acceleration or
otherwise, the due and punctual payment of interest on the overdue principal of
and interest, if any, on the Securities, to the extent lawful, and the due and
punctual performance of all other obligations of the Issuer to the Holders or
the Trustee, all in accordance with the terms of such Security and this
Indenture and (ii) in the case of any extension of time of payment or renewal of
any Securities or any of such other obligations, that the same will be promptly
paid in full when due or performed in accordance with the terms of the extension
or renewal, at Stated Maturity, by acceleration or otherwise. The Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger or bankruptcy of the Issuer, any
right to require a proceeding first against the Issuer, the benefit of
discussion, protest or notice with respect to any such Security or the debt
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged as to any such Security except by payment in full of the
principal thereof and interest thereon and as provided in Section 12.01 and
Section 12.02 (subject to Section 12.06) of the Indenture. The maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five of
the Indenture for the purposes of this Article One. In the

                                       2

<PAGE>

event of any declaration of acceleration of such obligations as provided in
Article Five of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Article One. In addition, without limiting the foregoing
provisions, upon the effectiveness of an acceleration under Article Five of the
Indenture, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article One.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or the Subsidiary Guarantor, or
any custodian, receiver, liquidator, trustee, sequestrator or other similar
official acting in relation to the Issuer, the Guarantor or the Subsidiary
Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Subsidiary Guarantor further agrees, to
the fullest extent that the Subsidiary Guarantor may lawfully do so, that, as
between the Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

<PAGE>

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Security unless the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 1.02. Obligations Unconditional. Subject to Section
1.05, nothing contained in this Article One or elsewhere in the Indenture or in
the Securities is intended to or shall impair, as among the Subsidiary Guarantor
and the holders of the Securities, the obligation of the Subsidiary Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the
holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
holders of the Securities and creditors of the Subsidiary Guarantor, nor shall
anything herein or therein prevent the holder of any Securities or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor
shall give prompt written notice to the Trustee of any fact known to the
Subsidiary Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee pursuant to the provisions of this Article
One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                  SECTION 2.01. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Second Supplemental Indenture or the Securities, and it shall not be
responsible for any statement of the Issuer or the Guarantor or the Subsidiary
Guarantor in this Second Supplemental Indenture.

shall remain in full force and effect. Upon execution, this Second Supplemental
Indenture shall form a part of the Indenture and the Second Supplemental
Indenture and the Indenture shall be read, taken and construed as one and the
same instrument for all purposes, and every holder of Securities heretofore or
hereafter authenticated and delivered under the Indenture shall be bound hereby.

                  SECTION 2.03. Effectiveness. This Second Supplemental
Indenture shall become effective as of the date first above written.

INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE

number of copies of this Second Supplemental Indenture. Each signed copy shall
be an original, but all of them together represent the same agreement. One
signed copy is enough to prove this Second Supplemental Indenture.

Opinion of Counsel to the Trustee pursuant to Section 9.03 of the Indenture;

                  WHEREAS, all other actions necessary to make this Second
Supplemental Indenture a legal, valid and binding obligation of the parties
hereto in accordance with its terms and the terms of the Indenture have been
performed; and

                  WHEREAS, the Issuer, the Guarantor, the Subsidiary Guarantor
and the Trustee desire to enter into, execute and deliver this Second
Supplemental Indenture in compliance with the provisions of the Indenture.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee
hereby agree as follows for the benefit of each other and for the equal and
ratable benefit of the Holders of the Notes:

                                    ARTICLE I
                              SUBSIDIARY GUARANTEE

                  SECTION 1.01. Guarantee. Subject to the provisions of this
Article One, the Subsidiary Guarantor hereby fully, unconditionally and
irrevocably guarantees to each Holder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
on and interest (including Special Interest) on each Security, when and as the
same shall become due and payable, whether at maturity, by acceleration or
otherwise, the due and punctual payment of interest on the overdue principal of
and interest, if any, on the Securities, to the extent lawful, and the due and
punctual performance of all other obligations of the Issuer to the Holders or
the Trustee, all in accordance with the terms of such Security and this
Indenture and (ii) in the case of any extension of time of payment or renewal of
any Securities or any of such other obligations, that the same will be promptly
paid in full when due or performed in accordance with the terms of the extension
or renewal, at Stated Maturity, by acceleration or otherwise. The Subsidiary
Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger or bankruptcy of the Issuer, any
right to require a proceeding first against the Issuer, the benefit of
discussion, protest or notice with respect to any such Security or the debt
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged as to any such Security except by payment in full of the
principal thereof and interest thereon and as provided in Section 12.01 and
Section 12.02 (subject to Section 12.06) of the Indenture. The maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five of
the Indenture for the purposes of this Article One. In the

                                       2
<PAGE>

event of any declaration of acceleration of such obligations as provided in
Article Five of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Article One. In addition, without limiting the foregoing
provisions, upon the effectiveness of an acceleration under Article Five of the
Indenture, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article One.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or the Subsidiary Guarantor, or
any custodian, receiver, liquidator, trustee, sequestrator or other similar
official acting in relation to the Issuer, the Guarantor or the Subsidiary
Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Subsidiary Guarantor further agrees, to
the fullest extent that the Subsidiary Guarantor may lawfully do so, that, as
between the Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Security unless the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 1.02. Obligations Unconditional. Subject to Section
1.05, nothing contained in this Article One or elsewhere in the Indenture or in
the Securities is intended to or shall impair, as among the Subsidiary Guarantor
and the holders of the Securities, the obligation of the Subsidiary Guarantor,
which is absolute and unconditional, upon failure by the Issuer, to pay to the
holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
holders of the Securities and creditors of the Subsidiary Guarantor, nor shall
anything herein or therein prevent the holder of any Securities or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor
shall give prompt written notice to the Trustee of any fact known to the
Subsidiary Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee pursuant to the provisions of this Article
One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee

ratable benefit of the Holders of the Notes:

                                   ARTICLE I
                              SUBSIDIARY GUARANTEE

         SECTION 1.01. Guarantee. Subject to the provisions of this Article One,
the Subsidiary Guarantor hereby fully, unconditionally and irrevocably
guarantees to each Holder and to the Trustee on behalf of the Holders: (i) the
due and punctual payment of the principal of, premium, if any, on and interest
(including Special Interest) on each Security, when and as the same shall become
due and payable, whether at maturity, by acceleration or otherwise, the due and
punctual payment of interest on the overdue principal of and interest, if any,

all other obligations of the Issuer to the Holders or the Trustee, all in
accordance with the terms of such Security and this Indenture and (ii) in the
case of any extension of time of payment or renewal of any Securities or any of
such other obligations, that the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, at Stated
Maturity, by acceleration or otherwise. The Subsidiary Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Issuer, any right to require a proceeding
first against the Issuer, the benefit of discussion, protest or notice with
respect to any such Security or the debt evidenced thereby and all demands
whatsoever, and covenants that this Guarantee will not be discharged as to any
such Security except by payment in full of the principal thereof and interest
thereon and as provided in Section 12.01 and Section 12.02 (subject to Section

be accelerated as provided in Article Five of the Indenture for the purposes of
this Article One. In the

                                       2
<PAGE>


event of any declaration of acceleration of such obligations as provided in
Article Five of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Article One. In addition, without limiting the foregoing
provisions, upon the effectiveness of an acceleration under Article Five of the
Indenture, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article One.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or the Subsidiary Guarantor, or
any custodian, receiver, liquidator, trustee, sequestrator or other similar
official acting in relation to the Issuer, the Guarantor or the Subsidiary
Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Subsidiary Guarantor further agrees, to
the fullest extent that the Subsidiary Guarantor may lawfully do so, that, as
between the Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Security unless the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

         SECTION 1.02. Obligations Unconditional. Subject to Section 1.05,
nothing contained in this Article One or elsewhere in the Indenture or in the
Securities is intended to or shall impair, as among the Subsidiary Guarantor and
the holders of the Securities, the obligation of the Subsidiary Guarantor, which
is absolute and unconditional, upon failure by the Issuer, to pay to the holders
of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms, or is intended to or shall affect the relative rights of the
holders of the Securities and creditors of the Subsidiary Guarantor, nor shall
anything herein or therein prevent the holder of any Securities or the Trustee
on their behalf from exercising all remedies otherwise permitted by applicable
law upon default under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

         SECTION 1.03. Notice to Trustee. The Subsidiary Guarantor shall give
prompt written notice to the Trustee of any fact known to the Subsidiary
Guarantor which would prohibit the making of any payment to or by the Trustee in
respect of the Guarantee pursuant to the provisions of this Article One.

         SECTION 1.05. Release of the Subsidiary Guarantor. The Subsidiary
Guarantor shall be automatically and unconditionally released and discharged
from its obligations under this Guarantee (i) upon any sale, exchange or
transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                  WHEREAS, the Issuer, the Guarantor and the Trustee entered
into the Indenture pursuant to which the Issuer issued its 9 7/8% Senior Notes
due 2009 (the "Securities");

                  WHEREAS, the Issuer desires to issue its euro denominated

                  WHEREAS, to facilitate the offering of the Dollar Notes and
the Euro Notes, the Subsidiary Guarantor is fully, unconditionally and
irrevocably guaranteeing, on an unsubordinated basis, all of the obligations of
the Issuer under the Dollar Notes, the Euro Notes and the indentures pursuant to
which they will be issued;

                  WHEREAS, Section 10.16 of the Indenture provides that the
Subsidiary Guarantor may not guarantee any Indebtedness of the Issuer unless the
Subsidiary Guarantor simultaneously executes and delivers a supplemental

Securities on the terms provided herein;

<PAGE>
                  WHEREAS, the Boards of Directors of the Issuer, the Guarantor
and the Subsidiary Guarantor have authorized the execution of the Second
Supplemental Indenture and its delivery to the Trustee;

                  WHEREAS, the Company and the Guarantor have delivered an
Opinion of Counsel to the Trustee pursuant to Section 9.03 of the Indenture;

                  WHEREAS, all other actions necessary to make this Second

performed; and

                  WHEREAS, the Issuer, the Guarantor, the Subsidiary Guarantor
and the Trustee desire to enter into, execute and deliver this Second
Supplemental Indenture in compliance with the provisions of the Indenture.

                  NOW, THEREFORE, the Issuer, the Guarantor and the Trustee
hereby agree as follows for the benefit of each other and for the equal and
ratable benefit of the Holders of the Notes:

                                   ARTICLE I
                              SUBSIDIARY GUARANTEE

                  SECTION 1.01. GuaranteeSECTION 5.01. Guarantee. Subject to the
provisions of this Article One, the Subsidiary Guarantor hereby fully,
unconditionally and irrevocably guarantees to each Holder and to the Trustee on
behalf of the Holders: (i) the due and punctual payment of the principal of,
premium, if any, on and interest (including Special Interest) on each Security,
when and as the same shall become due and payable, whether at maturity, by
acceleration or otherwise, the due and punctual payment of interest on the
overdue principal of and interest, if any, on the Securities, to the extent
lawful, and the due and punctual performance of all other obligations of the
Issuer to the Holders or the Trustee, all in accordance with the terms of such
Security and this Indenture and (ii) in the case of any extension of time of
payment or renewal of any Securities or any of such other obligations, that the
same will be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, at Stated Maturity, by acceleration or
otherwise. The Subsidiary Guarantor hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of merger or bankruptcy
of the Issuer, any right to require a proceeding first against the Issuer, the
benefit of discussion, protest or notice with respect to any such Security or
the debt evidenced thereby and all demands whatsoever, and covenants that this
Guarantee will not be discharged as to any such Security except by payment in
full of the principal thereof and interest thereon and as provided in Section
12.01 and Section 12.02 (subject to Section 12.06) of the Indenture. The
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article Five of the Indenture for the purposes of this Article One. In the

                                       2
<PAGE>

event of any declaration of acceleration of such obligations as provided in
Article Five of the Indenture, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Subsidiary Guarantor for the
purpose of this Article One. In addition, without limiting the foregoing
provisions, upon the effectiveness of an acceleration under Article Five of the
Indenture, the Trustee shall promptly make a demand for payment on the
Securities under the Guarantee provided for in this Article One.

                  If the Trustee or the Holder of any Security is required by
any court or otherwise to return to the Issuer or the Subsidiary Guarantor, or
any custodian, receiver, liquidator, trustee, sequestrator or other similar
official acting in relation to the Issuer, the Guarantor or the Subsidiary
Guarantor, any amount paid to the Trustee or such Holder in respect of a
Security, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. The Subsidiary Guarantor further agrees, to
the fullest extent that the Subsidiary Guarantor may lawfully do so, that, as
between the Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee, on the other hand, the maturity of the obligations guaranteed hereby
may be accelerated as provided in Article Five of the Indenture for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

                  Until such time as the Securities are fully and finally paid,
including all interest, premium, principal and liquidated damages with respect
thereto, the Subsidiary Guarantor hereby irrevocably waives any claim or other
rights which they may now or hereafter acquire against the Issuer that arise
from the existence, payment, performance or enforcement of their obligations
under this Guarantee and this Indenture, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution, indemnification,
any right to participate in any claim or remedy of the Holders against the
Issuer or any collateral which any such Holder or the Trustee on behalf of such
Holder hereafter acquires, whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or Security on
account of such claim or other rights. If any amount shall be paid to the
Subsidiary Guarantor in violation of the preceding sentence and the principal
of, premium, if any, and accrued interest on the Securities shall not have been
paid in full, such amount shall be deemed to have been paid to the Subsidiary
Guarantor for the benefit of, and held in trust for the benefit of, the Holders,
and shall forthwith be paid to the Trustee for the benefit of the Holders to be
credited and applied upon the principal of, premium, if any, and accrued
interest on the Securities. The Subsidiary Guarantor acknowledges that the
Subsidiary Guarantor has received and will receive direct and indirect benefits
from the issuance of the Securities pursuant to the Indenture and that the
waivers set forth in this Section 1.01 are knowingly made in contemplation of
such benefits.

                                       3
<PAGE>

                  The Guarantee set forth in this Section 1.01 shall not be or
become valid or obligatory for any purpose with respect to a Security unless the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

                  SECTION 1.02. Obligations UnconditionalSECTION 5.02.
Obligations Unconditional. Subject to Section 1.05, nothing contained in this
Article One or elsewhere in the Indenture or in the Securities is intended to or
shall impair, as among the Subsidiary Guarantor and the holders of the
Securities, the obligation of the Subsidiary Guarantor, which is absolute and
unconditional, upon failure by the Issuer, to pay to the holders of the
Securities the principal of, premium, if any, and interest on the Securities as
and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the holders of the
Securities and creditors of the Subsidiary Guarantor, nor shall anything herein
or therein prevent the holder of any Securities or the Trustee on their behalf
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture.

                  Without limiting the foregoing, nothing contained in this
Article One will restrict the right of the Trustee or the holders of the
Securities to take any action to declare the Guarantee to be due and payable
prior to the Stated Maturity of the Securities pursuant to Section 5.02 of the
Indenture or to pursue any rights or remedies hereunder.

                  SECTION 1.03. Notice to TrusteeSECTION 5.03. Notice to
Trustee. The Subsidiary Guarantor shall give prompt written notice to the
Trustee of any fact known to the Subsidiary Guarantor which would prohibit the
making of any payment to or by the Trustee in respect of the Guarantee pursuant
to the provisions of this Article One.

                  SECTION 1.05. Release of the Subsidiary Guarantor. The
Subsidiary Guarantor shall be automatically and unconditionally released and
discharged from its obligations under this Guarantee (i) upon any sale, exchange
or transfer, to any Person not an Affiliate of the Guarantor, of all of the
Guarantor's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all the assets of, the Subsidiary Guarantor (which sale, exchange
or transfer is not prohibited by the Indenture) or (ii) at any time, so long as
in the case of this clause (ii) Standard & Poor's Corporation, or any successor,
is notified by the Issuer of the proposed termination of the Guarantee of the
Subsidiary Guarantor and advises the Issuer that such termination would not
result in a downgrade of the rating on the Securities or placement of the
Securities on creditwatch with negative implications.

                  SECTION 2.01. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of

responsible for any statement of the Issuer or the Guarantor or the Subsidiary
Guarantor in this Second Supplemental Indenture.

Indenture shall form a part of the Indenture and the Second Supplemental

         The undersigned acknowledges that he or she has received and reviewed
the Prospectus, dated ___________, 2000, (the "Prospectus"), of RSL
Communications PLC ("RSL PLC"), and this Letter of Transmittal (the "Letter"),
which together constitute RSL PLC's offer (the "Exchange Offer") to exchange an
aggregate principal amount of up to US$100,000,000 of its 12 7/8% Senior Dollar
Exchange Notes Due 2010 (the "New Dollar Notes") of RSL PLC for a like principal
amount of the issued and outstanding 12 7/8% Senior Dollar Notes Due 2010 (the
"Old Dollar Notes") of RSL PLC from the holders thereof and an aggregate
principal amount of up to 100,000,000 of its 12 7/8% Senior Euro Exchange
Notes due 2010 (the "New Euro Notes" and, together with the New Dollar Notes,
the "New Notes") of RSL PLC for a like principal amount of the issued and
outstanding 12 7/8% Senior Euro Notes due 2010 (the "Old Euro Notes" and,
together with the Old Dollar Notes, the "Old Notes") of RSL PLC from the holders
thereof.

         For each Old Dollar Note and each Old Euro Note accepted for exchange,
the holder of such Old Dollar Note or Old Euro Note, as the case may be, will
receive a New Dollar Note or a New Euro Note, having a principal amount equal to
that of the surrendered Old Dollar Note or Old Euro Note, as the case may be.
The New Notes will bear interest from the most recent date to which interest has
been paid on the Old Notes, or, if no interest has been paid on the Old Notes,
from February 22, 2000. Accordingly, registered holders of New Notes on the
relevant record date for the first interest payment date following the
consummation of the Exchange Offer will receive interest accruing from the most
recent date to which interest has been paid or, if no interest has been paid,
from February 22, 2000. Old Notes accepted for exchange use will cease to accrue
interest from and after the date of consummation of the Exchange Offer. Holders
of Old Notes whose Old Notes are accepted for exchange will not receive any
payment in respect of accrued interest on such Old Notes.

         This Letter is to be completed by a holder of Old Notes if either
certificates are to be forwarded herewith or if a tender of certificates for Old
Notes, if available, is to be made by book-entry transfer to the account
maintained by the book-entry depositary at The Depository Trust Company, in the
case of the Old Dollar Notes, or Euroclear and Clearstream, in the case of the
Old Euro Notes (in either case, the "Book-Entry Transfer Facility"), pursuant to
the procedures set forth in "The Exchange Offers--Book-Entry Transfer" section
of the Prospectus and an Agent's Message is not delivered. Tenders by book-entry
transfer may also be made by delivering an Agent's Message in lieu of this
Letter. The term "Agent's Message" means a message, transmitted by the
Book-Entry Transfer Facility to and received by the Exchange Agent and forming a
part of a Book-Entry Confirmation (as defined below), which states that the
Book-Entry Transfer Facility has received an express acknowledgment from the
tendering participant, which acknowledgment states that such participant has
received and agrees to be bound by, and makes the representations and warranties
contained in, this Letter and that RSL PLC may enforce this Letter against such
participant. Holders of Old Notes whose certificates are not immediately
available, or who are unable to deliver their certificates or confirmation of
the book-entry tender of their Old Notes into the Book-Entry Depositary's
account at the Book-Entry Transfer Facility (the "Book-Entry Confirmation") and
all other documents required by this Letter to the Exchange Agent on or prior to
the Expiration Date, must tender their Old Notes according to the guaranteed
delivery procedures set forth in "The Exchange Offers--Guaranteed Delivery
Procedures" section of the Prospectus. See Instruction 1. Delivery of documents
to the Book-Entry Transfer Facility does not constitute delivery to the Exchange
Agent.

         The undersigned has completed the appropriate boxes below and signed
this Letter to indicate the action the undersigned desires to take with respect
to the Exchange offer.

         List below the Old Notes to which this Letter relates. If the space
provided below is inadequate, the certificate numbers and principal amount of
the Old Notes should be listed on a separate signed schedule affixed hereto.

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

         Upon the terms and subject to the conditions of the Exchange Offers,
the undersigned hereby tenders to RSL PLC the aggregate principal amount of Old
Notes indicated above. Subject to, and effective upon, the acceptance of
exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns
and transfers to, or upon the order of, RSL PLC all rights, title and interest
in and to such Old Notes as are being tendered hereby.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that RSL PLC will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim where the same are accepted by RSL PLC. The
undersigned hereby further represents that any New Notes acquired in exchange
for Old Notes tendered hereby will have been acquired in the ordinary course of
business of the person receiving such New Notes, whether or not such person is
the undersigned, that neither the holder of such Old Notes nor any such other
person has an arrangement or understanding with any person to participate in the
distribution of such New Notes and that neither the holder of such Old Notes nor
any such other person is an "affiliate," as defined in Rule 505 under the
Securities Act of 1933, as amended (the "Securities Act"), of RSL PLC, RSL
Communications, Ltd. ("RSL COM") or RSL U.S.A., Inc. ("RSL USA").

         The undersigned also acknowledges that these Exchange Offers are being
made in reliance on an interpretation by the staff of the SEC (the "Commission")
that the New Notes issued in exchange for the Old Notes pursuant to the Exchange
Offer may be offered for resale, resold and otherwise transferred by holders
thereof (other than any such holder that is an "affiliate" of RSL PLC, RSL COM
or RSL USA within the meaning of Rule 505 under the Securities Act), without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Notes are acquired in the ordinary course
of such holders' business and such holders have no arrangements with any person
to participate in the distribution of such New Notes. If the undersigned is not
a broker-dealer, the undersigned represents that it is not engaged in, and does
not intend to engage in, a distribution of New Notes. If the undersigned is a
broker-dealer that will receive New Notes for its own account in exchange for
Old Notes, it represents that the Old Notes to be exchanged for the New Notes
were acquired by it as a result of market-making activities or other trading
activities and acknowledges that it will deliver a prospectus in connection with
any resale of such New Notes; however, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

         The undersigned will, upon request, execute and deliver any additional
documents deemed by RSL PLC to be necessary or desirable to complete the sale,
assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer -- Withdrawal of Tenders"
section of the Prospectus.

         Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please deliver the New Notes (and, if applicable,
substitute certificates representing Old Notes for any Old Notes not exchanged)
in the name of the undersigned or, in the case of a book-entry delivery of Old
Notes, please credit the account indicated above maintained at the Book-Entry
Transfer Facility. Similarly, unless otherwise indicated under the box entitled
"Special Delivery Instructions" below, please send the New Notes (and, if
applicable, substitute certificates representing Old Notes for any Old Notes not
exchanged) to the undersigned at the address shown above in the box entitled
"Description of Old Notes."

manually signed facsimile hereof or Agent's Message in lieu thereof) and any
other documents required by this Letter, must be received by the Exchange Agent
at the address set forth herein or prior to the Expiration Date, or the
tendering holder must comply with the guaranteed delivery procedures set forth
below. Old Dollar Notes tendered hereby must be in denominations of principal
amount of US$1,000 and any integral multiple thereof. Old Euro Notes tendered
hereby must be in denominations of principal amount of 1,000 and any integral
multiple thereof.

         Noteholders whose certificates for Old Notes are not immediately
available or who cannot deliver their certificates and all other required
documents to the Exchange Agent on or prior to the Expiration Date, or who
cannot complete the procedure for book-entry transfer on a timely basis, may
tender their Old Notes pursuant to the guaranteed delivery procedures set forth
in "The Exchange Offers -- Guaranteed Delivery Procedures" section of the
Prospectus. Pursuant to such procedures, (i) such tender must be made through an
Eligible Institution, (ii) prior to 5:00 p.m., New York City time, on the
Expiration Date, the Exchange Agent must receive from such Eligible Institution
a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form provided by RSL PLC (by telegram, telex, facsimile
transmission, mail or hand delivery), setting forth the name and address of the
holder of Old Notes and the amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that within three New York Stock
Exchange ("NYSE") trading days after the date of execution of the Notice of
Guaranteed Delivery, the certificates for all physically tendered Old Notes, in
proper form for transfer, or a Book-Entry Confirmation, as the case may be,
together with a properly completed and duly executed Letter (or facsimile
thereof or Agent's Message in lieu thereof) with any required signature
guarantees and any other documents required by this Letter will be deposited by
the Eligible Institution with the Exchange Agent, and (iii) the certificates for
all physically tendered Old Notes, in proper form for transfer, or Book-Entry

executed Letter (or facsimile thereof or Agent's Message in lieu thereof) with
any required signature guarantees and all other documents required by this
Letter, are received by the Exchange Agent within three NYSE trading days after
the date of execution of the Notice of Guaranteed Delivery.

         The method of delivery of this Letter, the Old Notes and all other
required documents is at the election and risk of the tendering holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If Old Notes are sent by mail, it is suggested that the mailing
be made sufficiently in advance of the Expiration Date to permit delivery to the
Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date.

         See "The Exchange Offers" section of the Prospectus.

2.       Partial Tenders (not applicable to noteholders who tender by book-entry
         transfer).

         If less than all of the Old Notes evidenced by a submitted certificate
are to be tendered, the tendering holder(s) should fill in the aggregate
principal amount of Old Notes to be tendered in the box above entitled
"Description of Old Notes -- Principal Amount at Maturity Tendered." A reissued
certificate representing the balance of nontendered Old Notes will be sent to
such tendering holder, unless otherwise provided in the appropriate box on this
Letter, promptly after the Expiration Date. All of the Old Notes delivered to
the Exchange Agent will be deemed to have been tendered unless otherwise
indicated.

3.       Signatures on this Letter; Bond Powers and Endorsements; Guarantee of
         Signatures.

         If this Letter is signed by the registered holder of the Old Notes
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificate without any change whatsoever.

         If any tendered Old Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter.

         If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this Letter as there are different registrations of certificates.

         When this Letter is signed by the registered holder or holders of the
Old Notes specified herein and tendered hereby, no endorsements of certificates
or separate bond powers are required. If, however, the New Notes are to be
issued, or any untendered Old Notes are to be reissued, to a person other than
the registered holder, then endorsements of any certificates transmitted hereby
or separate bond powers are required. Signatures on such certificate(s) must be
guaranteed by an Eligible Institution.

         If this Letter is signed by a person other than the registered holder
or holders of any certificate(s) specified herein, such certificate(s) must be
endorsed or accompanied by appropriate bond powers, in either case signed
exactly as the name or names of the registered holder or holders appear(s) on
the certificate(s) and signatures on such certificate(s) must be guaranteed by
an Eligible Institution.

         If this Letter or any certificates or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
person should so indicate when signing, and, unless waived by RSL PLC, proper
evidence satisfactory to RSL PLC of their authority to so act must be submitted.

         Endorsements on certificates for Old Notes or signatures on bond powers
required by this Instruction 3 must be guaranteed by a firm which is a member of
a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc. or by a commercial bank or trust company
having an officer or correspondent in the United States (an "Eligible
Institution").

         Signatures on this Letter need not be guaranteed by an Eligible
Institution, provided the Old Notes are tendered: (i) by a registered holder of
Old Notes (which term, for purposes of the Exchange Offer, includes any
participant in the Book-Entry Transfer Facility system whose name appears on a
security position listing as the holder of such Old Notes) who has not completed
the box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on this Letter, or (ii) for the account of an Eligible
Institution.

5.       Special Issuance and Delivery Instructions.

         Tendering holders of Old Notes should indicate in the applicable box
the name and address to which New Notes issued pursuant to the Exchange Offer
and/or substitute certificates evidencing Old Notes not exchanged are to be
issued or sent, if different from the name or address of the person signing this
Letter. In the case of issuance in a different name, the employer identification
or social security number of the person named must also be indicated.
Noteholders tendering Old Notes by book-entry transfer may request that Old
Notes not exchanged be credited to such account maintained at the Book-Entry
Transfer Facility as such noteholder may designate hereon. If no such

<PAGE>

instructions are given, such Old Notes not exchanged will be returned to the
name or address of the person signing this Letter.

5.       Tax Identification Number.

         U.S. Federal income tax law generally requires that a tendering holder
whose Old Notes are accepted for exchange must provide RSL PLC (as payer) with
such holder's correct Taxpayer Identification Number ("TIN") on Substitute Form
W-9 below, which in the case of a tendering holder who is an individual, is his
or her social security number. If RSL PLC is not provided with the current TIN
or an adequate basis for an exemption, such tendering holder may be subject to a
US$50 penalty imposed by the Internal Revenue Service. In addition, delivery to
such tendering holder of New Notes may result in backup withholding in an amount
equal to 31% of all reportable payments made after the exchange. If withholding
results in an overpayment of taxes, a refund may be obtained.

         Exempt holders of Old Notes (including, among others, all corporations
and certain foreign individuals) are not subject to these backup withholding and
reporting requirements. See the enclosed Guidelines of Certification of Taxpayer
Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for
additional instructions.

         To prevent backup withholding, each tendering holder of Old Notes must
provide its correct TIN by completing the Substitute Form W-9 set forth below,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN) and that (i) the holder is exempt from backup withholding, or (ii) the
holder has not been notified by the Internal Revenue Service that such holder is
subject to backup withholding as a result of a failure to report all interest or
dividends or (iii) the Internal Revenue Service has notified the holder that
such holder is no longer subject to backup withholding. If the tendering holder
of Old Notes is a nonresident alien or foreign entity not subject to backup
withholding, such holder must give RSL PLC a completed Form W-8, Certificate of
Foreign Status. These forms may be obtained from the Exchange Agent. If the Old
Notes are in more than one name or are not in the name of the actual owner, such
holder should consult the W-9 Guidelines for information on which TIN to report.
If such holder does not have a TIN, such holder should consult the W-9
Guidelines for instructions on applying for a TIN, check the box in Part 2 of
the Substitute Form W-9 and write "applied for" in lieu of its TIN. Note:
Checking this box and writing "applied for" on the form means that such holder
has already applied for a TIN or that such holder intends to apply for one in
the near future. If such holder does not provide its TIN to RSL PLC within 60
days, backup withholding will begin and continue until such holder furnishes its
TIN to RSL PLC.

6.       Transfer Taxes.

         RSL PLC will pay all transfer taxes, if any, applicable to the transfer
of Old Notes to it or its order pursuant to the Exchange Offer. If however, New
Notes and/or substitute Old Notes not exchanged are to be delivered to, or are
to be registered or issued in the name of, any person other than the registered
holder of the Old Notes tendered hereby, or if tendered Old Notes are registered
in the name of any person other than the person signing this Letter, or if a
transfer tax is imposed for any reason other than the transfer of Old Notes to
RSL PLC or its order pursuant to the Exchange Offer, the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted herewith, the amount of such
transfer taxes will be billed directly to such tendering holder.

         Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter.

7.       No Conditional Tenders.

         No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Notes, by execution of this Letter or an
Agent's Message in lieu thereof, shall waive any right to receive notice of the
acceptance of their Old Notes for exchange.

8.       Mutilated, Lost, Stolen or Destroyed Old Notes.

         Any holder whose Old Notes have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.

9.       Requests for Assistance or Additional Copies.

         Questions relating to the procedure for tendering, as well as requests
for additional copies of the Prospectus and this Letter, may be directed to the
Exchange Agent, at the address and telephone number indicated above.
