Ladies and Gentlemen:

            FLAG Telecom Holdings Limited, a company organized under the laws of
Bermuda (the "Company"), proposes to issue and sell to the parties named in
Schedule I hereto (the "Initial Purchasers"), for whom you are acting as
representatives (the "Representatives"), $300,000,000 aggregate principal amount
at maturity of its 11.625% Senior Dollar Notes Due 2010 (the "Dollar Notes") and
(euro)300,000,000 aggregate principal amount at maturity of its 11.625% Senior
Euro Notes Due 2010 (the "Euro Notes" and, together with the Dollar Notes, the
"Securities"). The Securities are to be issued under two separate indentures
(the "Indentures") to be dated as of March 17, 2000 between the Company and Bank
of New York, as trustee . If you are the only Initial Purchasers, all references
herein to the Representatives shall be deemed to be to the Initial Purchasers.

            The sale of the Securities to the Initial Purchasers will be made
without registration of the Securities under the Securities Act of 1933, as
amended (the "Securities Act"), in reliance upon exemptions from the
registration requirements of the Securities Act. You have advised the Company
that the Initial Purchasers will offer and sell the Securities purchased by them
hereunder in accordance with Section 4 hereof as soon as you deem advisable.

            The holders of the Securities will be entitled to the benefits of a
Registration Agreement to be dated as of March 17, 2000 between the Company and
Salomon Smith Barney Inc. (the "Registration Agreement"), pursuant to which the
Company will agree to file a registration statement with the Securities and
Exchange Commission (the "Commission") registering the Securities or New
Securities (referred to in the Registration Agreement) under the Securities Act.

<PAGE>

            In connection with the sale of the Securities, the Company has
prepared a preliminary offering memorandum, dated March 3, 2000 (including any
and all exhibits thereto, the "Preliminary Memorandum") and a final offering
memorandum, dated March 14, 2000 (as amended or supplemented at the Execution
Time (as defined below), including any and all exhibits thereto, the "Final
Memorandum"). Each of the Preliminary Memorandum and the Final Memorandum sets
forth certain information concerning the Company and the Securities. The Company
hereby confirms that it has authorized the use of the Preliminary Memorandum and
the Final Memorandum, and any amendment or supplement thereto, in connection
with the offer and sale of the Securities by the Initial Purchasers.

            1. Representations and Warranties. The Company represents and
warrants to each Initial Purchaser as set forth below in this Section 1.

            (a) The Preliminary Memorandum, at the date thereof, did not contain
      any untrue statement of a material fact or omit to state any material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading. At the Execution
      Time and on the Closing Date, the Final Memorandum did not, and will not
      (and any amendment or supplement thereto, at the date thereof and at the
      Closing Date, will not), contain any untrue statement of a material fact
      or omit to state any material fact necessary in order to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading; provided, however, that the Company
      makes no representation or warranty as to the information
      contained in or omitted from the Preliminary Memorandum or the Final
      Memorandum, or any amendment or supplement thereto, in reliance upon and
      in conformity with information furnished in writing to the Company by or
      on behalf of the Initial Purchasers through the Representatives
      specifically for inclusion therein.

            (b) Each of the Company, FLAG Atlantic Holdings Limited, FLAG
      Atlantic Limited and the Company's significant subsidiaries as identified
      on Schedule II hereto (referred to herein, together with FLAG Atlantic
      Holdings Limited and FLAG Atlantic Limited, as the "subsidiaries") has
      been duly incorporated and is validly existing as a corporation or company
      in good standing under the laws of the jurisdiction in which it is
      chartered or organized with the requisite corporate power and authority to
      own or lease, as the case may be, and to operate its properties and
      conduct its business as described in the Final Memorandum.

            (c) All the outstanding shares of capital stock of each subsidiary
      of the Company have been duly and validly authorized and issued and are
      fully paid and nonassessable, and, except as otherwise set forth in the
      Final Memorandum, all outstanding shares of capital stock of the
      subsidiaries are owned by the Company either directly or through wholly
      owned subsidiaries free and clear of any perfected security interest or
      any other security interests, claims, liens or encumbrances.

            (d) The Company has all requisite corporate power and authority to
      enter into and to perform its obligations under this Agreement, the
      Indentures, the Registration Agreement and the Securities.

<PAGE>

            (e) The Company has an authorized, issued and outstanding common
      stock capitalization as set forth in the Final Memorandum under the
      heading "Capitalization." All of the issued and outstanding shares of
      capital stock of the Company have been duly authorized and validly issued
      and are fully paid and nonassessable.

            (f) The financial statements and schedules of the Company and FLAG
      Limited included in the Final Memorandum fairly present the financial
      position of the Company and its consolidated subsidiaries and the results
      of operations and changes in financial condition as of the dates and for
      the periods therein specified. Such financial statements and schedules
      have been prepared in accordance with generally accepted accounting
      principles of the United States of America consistently applied throughout
      the periods involved (except as otherwise noted therein). The selected
      financial data set forth under the captions "Summary Financial Data" and
      "Selected Financial Data" in the Final Memorandum fairly present, on the
      basis stated in the Final Memorandum, the information included therein.

            (g) Arthur Andersen & Co., who have certified certain financial
      statements of the Company and its consolidated subsidiaries and delivered
      their report with respect to the audited financial statements and
      schedules included in the Final Memorandum, are independent public
      accountants with respect to the Company within the meaning of the
      Securities Act and the applicable published rules and regulations
      thereunder.

            (h) This Agreement has been duly authorized, executed, and delivered
      by the Company.

            (i) The Registration Agreement has been duly authorized by the
      Company and, when duly executed and delivered by the Company, will
      constitute a legal, valid and binding obligation of the Company
      enforceable against the Company in accordance with its terms (subject, as
      to the enforcement of remedies, to applicable bankruptcy, reorganization,
      insolvency, fraudulent conveyance, moratorium or other laws affecting
      creditors', rights generally from time to time in effect, general
      principles of equity (whether considered in a proceeding in equity or at
      law) and to the possible unenforceability of the indemnification or
      contribution provisions contained therein).

            (j) Each of the Indentures has been duly authorized by the Company
      and, when duly executed and delivered by the Company and the Trustee, will
      constitute a valid and binding instrument enforceable against the Company
      in accordance with its terms (subject, as to the enforcement of remedies,
      to applicable bankruptcy, reorganization, insolvency, fraudulent
      conveyance, moratorium or other laws affecting creditors' rights generally
      from time to time in effect, and general principles of equity (whether
      considered in a proceeding in equity or at law)); the Securities have been
      duly and validly authorized and, when executed and authenticated in
      accordance with the provisions of the related Indenture and delivered to
      and paid for by the Initial Purchasers pursuant to this Agreement, will
      constitute valid and binding obligations of the Company (subject, as to
      the enforcement of remedies, to applicable bankruptcy, reorganization,
      insolvency, fraudulent conveyance, moratorium or other laws affecting
      creditors' rights generally from time to time in effect, and to general
      equitable principles (whether considered in a


                                       3
<PAGE>

      proceeding in equity or at law)) entitled to the benefits of the related
      Indenture; and the statements set forth under the heading "Description of
      Notes" in the Final Memorandum, insofar as such statements purport to
      summarize certain provisions of the Securities and the Indentures, provide
      a fair summary of such provisions.

            (k) No action, suit or proceeding by or before any court or
      governmental agency, authority or body or any arbitrator involving the
      Company or any of its subsidiaries or its or their property is pending or,
      to the best knowledge of the Company, threatened that (i) would have a
      material adverse effect on the performance by the Company of this
      Agreement or the consummation of any of the transactions contemplated
      hereby or (ii) would have a material adverse effect on the condition
      (financial or otherwise), prospects, earnings, business or properties of
      the Company and its subsidiaries, taken as a whole, whether or not arising
      from transactions in the ordinary course of business (a "Material Adverse
      Effect"), except as set forth in or contemplated in the Final Memorandum
      (exclusive of any supplement thereto).

            (l) The Company has filed all foreign, federal, state and local tax
      returns that are required to be filed or has requested extensions thereof
      (except in any case in which the failure so to file would not have a
      Material Adverse Effect) and has paid all taxes required to be paid by it
      and any other assessment, fine or penalty levied against it, to the extent
      that any of the foregoing is due and payable, except for any such tax
      assessment, fine or penalty that is currently being contested in good
      faith or as would not have a Material Adverse Effect.

            (m) The issuance, offering and sale of the Securities to the Initial
      Purchasers by the Company pursuant to this Agreement, the performance by
      the Company of its obligations under this Agreement, the Registration
      Agreement, the Indentures and the Securities, the consummation of the
      transactions herein and therein and the application of proceeds from the
      sale of the Securities as described in the Final Memorandum (i) do not
      require the consent, approval, authorization, registration or
      qualification of or with any governmental authority, except such as have
      been obtained and such as may be required under state securities or blue
      sky laws and the filing of the Final Memorandum with the Registrar of
      Companies of Bermuda and the consent of the Bermuda Monetary Authority,
      and except as may be required under the Securities Act and the rules and
      regulations thereunder with respect to the Registration Agreement and
      transactions contemplated thereunder and (ii) will not at the time of such
      sale, performance, consummation and application, conflict with or result
      in a breach or violation of, or imposition of any lien, charge or
      encumbrance upon any property or assets of the Company or any of its
      subsidiaries pursuant to, any of the terms and provisions of, or
      constitute a default under, any indenture, mortgage, deed of trust, lease
      or other material agreement or instrument to which the Company or any of
      its subsidiaries is a party or by which the Company's or any of is
      subsidiaries' property is bound, or the charter documents or by-laws of
      the Company or any of its subsidiaries, or any statute or any judgment,
      decree, order, rule or regulation of any court or other governmental
      authority or any arbitrator applicable to the Company or any of its
      subsidiaries.

<PAGE>

            (n) Subsequent to the respective dates as of which information is
      given in the Final Memorandum, (i) neither the Company nor any of its
      subsidiaries has incurred any material liability or obligation, direct or
      contingent, nor entered into any material transaction not in the ordinary
      course of business except in each case as set forth or contemplated in the
      Final Memorandum (exclusive of any amendment or supplement thereto); (ii)
      the Company has not purchased any of its outstanding capital stock, nor
      declared, paid or otherwise made any dividend or distribution of any kind
      on its capital stock; (iii) there has not been any material change in the
      capital stock, short-term debt or long-term debt of the Company and its
      subsidiaries, except in each case as set forth in or contemplated by the
      Final Memorandum (exclusive of any amendment or supplement thereto); and
      (iv) there has not been any material adverse change in the condition
      (financial or otherwise), prospects, earnings, business or properties of
      the Company and its subsidiaries, taken as a whole, whether or not arising
      from transactions in the ordinary course of business.

            (o) Each of the Company and its subsidiaries owns or leases all such
      properties as are necessary to the conduct of its operations as presently
      conducted.

            (p) The Company and each of its subsidiaries are insured by insurers
      of recognized financial responsibility against such losses and risks and
      in such amounts as are prudent and customary in the businesses in which
      they are engaged; all policies of insurance and fidelity or surety bonds
      insuring the Company or any of its subsidiaries or their respective
      businesses, assets, employees, officers and directors are in full force
      and effect; the Company and its subsidiaries are in compliance with the
      terms of such policies and instruments in all material respects; and there
      are no claims by the Company or any of its subsidiaries under any such
      policy or instrument as to which any insurance company is denying
      liability or defending under a reservation of rights clause; neither the
      Company nor any such subsidiary has been refused any insurance coverage
      sought or applied for; and neither the Company nor any such subsidiary has
      any reason to believe that it will not be able to renew its existing
      insurance coverage as and when such coverage expires or to obtain similar
      coverage from similar insurers as may be necessary to continue its
      business at a cost that would not have a Material Adverse Effect, except
      as set forth in or contemplated by the Final Memorandum (exclusive of any
      amendment or supplement thereto).

            (q) No subsidiary of the Company is currently prohibited, directly
      or indirectly, from paying any dividends to the Company, from making any
      other distribution on such subsidiary's capital stock, from repaying to
      the Company any loans or advances to such subsidiary from the Company or
      from transferring any of such subsidiary's property or assets to the
      Company or any other subsidiary of the Company, except as set forth in or
      contemplated by the Final Memorandum (exclusive of any amendment or
      supplement thereto).

            (r) The Company and its subsidiaries possess all licenses,
      certificates, permits and other authorizations issued by the appropriate
      federal, state or foreign regulatory authorities necessary to conduct
      their respective businesses as presently conducted, except for those the
      failure to obtain which would not have a Material Adverse Effect,


                                       5
<PAGE>

      and neither the Company nor any such subsidiary has received any notice of
      proceedings relating to the revocation or modification of any such
      certificate, authorization or permit which, singly or in the aggregate, if
      the subject of an unfavorable decision, ruling or finding, would have a
      Material Adverse Effect, in each case except as set forth in or
      contemplated by the Final Memorandum (exclusive of any amendment or
      supplement thereto).

            (s) Each certificate signed by any officer of the Company and
      delivered to the Representatives or counsel for the Initial Purchasers
      shall be deemed to be a representation and warranty by the Company (and
      not individually by such officer) to the Initial Purchasers as to the
      matters covered thereby.

            (t) Neither the Company nor any subsidiary is in violation or
      default of (i) any provision of its charter or bylaws; (ii) the terms of
      any indenture, contract, lease, mortgage, deed of trust, note agreement,
      loan agreement or other agreement, obligation, condition, covenant or
      instrument to which it is a party or bound or to which its property is
      subject; or (iii) any statute, law, rule, regulation, judgment, order or
      decree applicable to the Company or any of its subsidiaries of any court,
      regulatory body, administrative agency, governmental body, arbitrator or
      other authority having jurisdiction over the Company or such subsidiary or

Delivery of the Securities shall be made to the Representatives for the
respective accounts of the Initial Purchasers against payment by the Initial

      Securities except (i) to those it reasonably believes to be qualified
      institutional buyers (as defined in Rule 144A under the Securities Act)
      and that, in connection with each such sale, it has taken or will take
      reasonable steps to ensure that the purchaser of such Securities is aware
      that such sale is being made in reliance on Rule 144A, or (ii) in
      accordance with the restrictions set forth in Exhibit A hereto.

            (b) Neither it nor any person acting on its behalf has made or will
      make offers or sales of the Securities by means of any form of general
      solicitation or general advertising (within the meaning of Regulation D)
      or in any manner involving a public offering within the meaning of Section
      4(2) of the Securities Act in the United States or, with respect to
      Securities to be sold in reliance on Regulation S, by means of any
      directed selling efforts.

            (c) It is a qualified institutional buyer (as defined in Rule 144A
      under the Securities Act) and it will offer the Securities for resale only

            5. Agreements. The Company agrees with each Initial Purchaser that:

            (a) The Company will furnish to each Initial Purchaser and to
      counsel for the Initial Purchasers, without charge, during the period
      referred to in paragraph (c) below, as many copies of the Final Memorandum
      and any amendments and supplements thereto it may reasonably request.

            (b) The Company will not amend or supplement the Final Memorandum
      without the prior consent of the Initial Purchasers as contemplated by
      paragraph (c) below.

            (c) If at any time prior to the completion of the sale of the
      Securities by the Initial Purchasers (as determined by the
      Representatives), any event occurs as a result of which the Final
      Memorandum, as then amended or supplemented, would include any untrue
      statement of a material fact or omit to state any material fact necessary
      to make the statements therein, in the light of the circumstances under
      which they were made, not misleading, or if it should be necessary to
      amend or supplement the Final Memorandum to comply with applicable law,
      the Company will promptly notify the Representatives of the same and,
      subject to the requirements of paragraph (b) of this Section 5, will
      prepare and, provide as promptly as practicable to the Representatives
      pursuant to paragraph (a) of this Section 5 an amendment or supplement
      which will correct such statement or omission or effect such compliance.

            (d) The Company will use its best efforts to arrange for the
      qualification of the Securities for sale by the Initial Purchasers under
      the laws of such jurisdictions as the Initial Purchasers may reasonably
      designate and will use its best efforts to maintain such qualifications in
      effect so long as required for the sale of the Securities. Notwithstanding
      the foregoing, the Company shall not be obligated to qualify as a foreign
      corporation in any jurisdiction in which it is not so qualified, to file a
      general consent to service of process in any jurisdiction or to take any
      action which would result in its being required to pay taxes in any
      jurisdiction where it is not currently required to do so. The Company will
      promptly advise the Representatives of the receipt by the Company of any
      notification with respect to the suspension of the qualification of the
      Securities for sale in any jurisdiction or the initiation or threatening
      of any proceeding for such purpose.

            (e) The Company will not resell any Securities that have been
      acquired by the Company.

            (f) The Company (i) will not, directly or indirectly, make offers or
      sales of any security, or solicit offers to buy any security, under
      circumstances that would require the registration of the securities under
      the Securities Act and (ii) will use its best efforts to cause any of its
      Affiliates or any person authorized to act on its or their behalf not to
      engage, directly or indirectly, in the activities described in (i) above.

            (g) The Company (i) will not engage in any form of general
      solicitation or general advertising (within the meaning of Regulation D)
      in connection with any offer or sale of the Securities in the United
      States and (ii) will use its best efforts to cause any of its


                                       10
<PAGE>

      Affiliates, or any person authorized to act on its or their behalf not to
      engage in the activities described in (i) above.

            (h) So long as any of the Securities are "restricted securities"
      within the meaning of Rule 144(a)(3) under the Securities Act, the Company
      will, during any period in which it is not subject to and in compliance
      with Section 13 or 15(d) of the Exchange Act and it is not exempt from
      such reporting requirements pursuant to and in compliance with Rule
      12g3-2(b) under the Exchange Act, provide to each holder of such
      restricted securities and to each prospective purchaser (as designated by
      such holder) of such restricted securities, upon the request of such
      holder or prospective purchaser, any information required to be provided
      by Rule 144A(d)(4) under the Securities Act and such information will not,
      as of the date of such information, contain any untrue statement of a
      material fact or omit to state any material fact necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading. This covenant is intended to be for the benefit
      of the holders, and the prospective purchasers designated by such holders,
      from time to time of such restricted securities.

            (i) The Company (i) will not engage in any directed selling efforts
      with respect to the Securities and (ii) will use its best efforts to cause
      any of its Affiliates or any person authorized to act on its or their
      behalf not to engage in the activities described in (i), and the Company
      will and will use its best efforts to cause each of the others to comply
      with the offering restrictions requirement of Regulation S. Terms used in
      this paragraph have the meanings given to them by Regulation S.

            (j) The Company will cooperate with the Representatives and use its
      best efforts to permit the Dollar Notes to be eligible for clearance and
      settlement through The Depository Trust Company and to permit the Euro
      Notes to be eligible for clearance and settlement through Euroclear and
      Clearstream, Luxembourg (each as defined in the Indentures).

            (k) The Company will use the net proceeds received by it from the
      sale of the Securities in the manner specified in the Final Memorandum
      under "Use of Proceeds."

            6. Conditions to the Obligations of the Initial Purchasers. The
obligations of the Initial Purchasers to purchase the Securities shall be
subject to the accuracy of the representations and warranties on the part of the
Company contained herein at the date and time that this Agreement is executed

            Company under New York law;

            the heading "Tax Considerations--Taxation of the Company--United
            States Federal Income Tax Considerations" fairly summarizes in all
            material respects the matters therein described and to the extent
            that such statements purport to describe certain provisions of U.S.
            federal laws, rules or regulations, have been reviewed by such
            counsel and are correct as to legal matters in all material
            respects;

                  (iii) assuming the due authorization of the Indentures by the
            Company under Bermuda law, each of the Indentures has been duly
            executed and delivered and constitutes a legal, valid and binding
            instrument enforceable against the Company in accordance with its
            terms (subject, as to the enforcement of remedies, to applicable
            bankruptcy, reorganization, insolvency, fraudulent conveyance,
            moratorium or other laws affecting creditors' rights generally from
            time to time in effect, and to general principles of equity (whether
            considered in a proceeding in equity or at law)); when the
            Securities have been duly and validly authorized and are executed
            and authenticated in accordance with the provisions of the related
            Indenture, and when the Securities are delivered to and paid for by
            the Initial Purchasers pursuant to this Agreement, the Securities
            will constitute legal, valid and binding obligations of the Company
            (subject, as to the enforcement of remedies, to applicable
            bankruptcy, reorganization, insolvency, fraudulent conveyance,
            moratorium or other laws affecting creditors' rights generally from
            time to time in effect, and to general equitable principles)
            entitled to the benefits of the related Indenture; and the
            Securities and the Indentures conform as to legal matters in all
            material respects to the descriptions thereof set forth under the
            heading "Description of Notes" in the Final Memorandum;

            remedies, to applicable bankruptcy, reorganization, insolvency,
            fraudulent conveyance, moratorium or other laws affecting creditors'
            rights generally from time to time in effect, and to general
            principles of equity), and further such counsel expresses no opinion
            as to (i) the enforceability of the indemnification or contribution
            provisions contained therein or (ii) the enforceability of any
            provision of the Registration Agreement that requires or relates to
            the payment of any interest at a rate or in an amount which a court
            would determine in the circumstances under applicable law to be
            commercially unreasonable or a penalty or a forfeiture, and the
            Registration Agreement conforms as to legal matters in all material
            respects to the description thereof contained in the Final
            Memorandum;

                  (v) to the best of such counsel's knowledge, no consent,
            approval, authorization or order of any court or governmental agency
            or body (other than such as may be required under the applicable
            securities laws of the various jurisdictions in which the Securities
            will be offered or sold, as to which such counsel expresses not
            opinion, or as required in connection with the

            prospectus filed as part of a registration statement on Form F-1
            under the Securities Act, that is not described or referred to as
            would be so required, and the descriptions thereof or references

            or the terms of any material indenture or other material agreement
            or instrument to which the Company or any of its subsidiaries is a

                  (viii) assuming the accuracy of the representations and
            warranties and compliance with the agreements contained in this
            Agreement, no registration of the Securities under the Securities
            Act is required, and no qualification of the Indentures under the
            Trust Indenture Act of 1939 is necessary, for the purchase by the
            Initial Purchases of the Securities, or the offer and sale by the
            Initial Purchasers of the Securities, in each case, in the manner
            contemplated by this Agreement (and not taking into account the
            transactions contemplated by the Registration Agreement);


                                       13

                  (ix) the Company is not and, after giving effect to the
            offering and sale of the Securities and the application of the
            proceeds thereof as described in the Final Memorandum, will not be
            an "investment company" within the meaning of the Investment Company
            Act of 1940, as amended.

            Such counsel shall also state that they have no reason to believe
that at the Execution Time or at the Closing Date the Final Memorandum contained
an untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
that such counsel expresses no belief as to the financial statements, including
the notes thereto, or supporting schedules or other financial, statistical and
accounting data included in the Final Memorandum.

            All references in this Section 6(a) to the Final Memorandum shall be
deemed to include any amendment or supplement thereto at the Closing Date

            (b) The Company shall have requested and caused Appleby, Spurling &
      Kempe, Bermuda counsel for the Company, to have furnished to the
      Representatives their opinion, dated the Closing Date and addressed to the
      Representatives, to the effect that:

                  (i) the Company and each of its subsidiaries organized under
            the laws of Bermuda has been duly organized and is validly existing
            as a company in good standing under the laws of Bermuda, with full
            corporate power and authority to own or lease its properties and
            conduct its business as described in the Final Memorandum, and the
            Company has full corporate power and authority to enter into and
            perform its obligations under this Agreement, the Registration
            Agreement, the Indentures and the Securities;

                  (ii) all of the outstanding shares of capital stock of the
            Company have been duly and validly authorized and issued and are
            fully paid and nonassessable, and the Company's authorized common
            stock capitalization is as set forth in the Final Memorandum under
            the heading "Capitalization";

                  (iii) all the outstanding shares of capital stock of each
            subsidiary organized under the laws of Bermuda have been duly and
            validly authorized and issued and are fully paid and nonassessable
            and, except as otherwise set forth in the Final Memorandum, all
            outstanding shares of capital stock of the subsidiaries are owned by
            the Company either directly or through wholly owned subsidiaries
            free and clear of any security interest and, to the knowledge of
            such counsel, after due inquiry, any other security interest, claim,
            lien or encumbrance;

                  (iv) each of this Agreement, the Registration Agreement, the
            Indentures and the Securities has been duly authorized by the
            Company;

                  (v) to the best of such counsel's knowledge, no consent,
            approval, authorization or order of any court or governmental agency
            or body of Bermuda (other than the filing of the Final Memorandum
            with the Registrar of Companies and the consent of the Bermuda
            Monetary Authority) is required in connection


                                       14
<PAGE>

            with the due authorization, execution and delivery of this
            Agreement, the Registration Agreement, the Indentures or the
            Securities, the performance by the Company of its obligations
            thereunder, the consummation of the transactions therein, the
            application of proceeds from the sale of the Securities as described
            in the Final Memorandum or for the issuance, offering and sale or
            delivery of the Securities to the Initial Purchasers or the resale
            of the Securities by the Initial Purchasers in accordance with this
            Agreement;

                  (vi) neither the issue and sale of the Securities, nor the
            consummation of any other of the transactions contemplated in this
            Agreement nor the fulfillment of the terms of this Agreement will
            conflict with, result in a breach or violation of or imposition of
            any lien, charge or encumbrance upon any property or assets of the
            Company or its subsidiaries pursuant to, (i) the charter or by-laws
            of the Company or its subsidiaries or (ii) any statute, law, rule,
            regulation, judgment, order or decree applicable to the Company or
            its subsidiaries of any court, regulatory body, administrative
            agency, governmental body, arbitrator or other authority having
            jurisdiction over the Company or its subsidiaries or any of its or
            their properties; and

                  (vii) the choice of law provision set forth in Section 14
            hereof is legal, valid and binding under the laws of Bermuda and
            such counsel knows of no reason why the courts of Bermuda would not
            give effect to the choice of New York law as the proper law of this
            Agreement; the Company has the legal capacity to sue and be sued in
            its own name under the laws of Bermuda; the Company has the power to
            submit, and has irrevocably submitted, to the non-exclusive
            jurisdiction of the New York Courts; the irrevocable submission of
            the Company to the non-exclusive jurisdiction of the New York Courts
            and the waivers by the Company of any immunity and any objection to
            the venue of the proceeding in a New York Court herein are legal,
            valid and binding under the laws of Bermuda and such counsel knows
            of no reason why the courts of Bermuda would not give effect to the
            submission and waivers; service of process in the manner set forth
            in Section 17 hereof, will be effective to confer valid personal
            jurisdiction over the Company under the laws of Bermuda; and the
            courts in Bermuda will recognize as valid and final, and will
            enforce, any final and conclusive judgment against the Company
            obtained in a New York Court arising out of or in relation to the
            obligations of the Company under this Agreement.

            All references in this Section 6(b) to the Final Memorandum shall be
deemed to include any amendment or supplement thereto at the Closing Date.

            (c) The Company shall have requested and caused Stuart Rubin,
      General Counsel for the Company, to have furnished to the Representatives
      his opinion, dated the Closing Date and addressed to the Representatives,
      in form and substance satisfactory to the Representatives, relating to
      certain regulatory matters in respect of the Company and certain of its
      subsidiaries.


                                       15
<PAGE>

            (d) The Representatives shall have received from Cleary, Gottlieb,
      Steen & Hamilton, counsel for the Initial Purchasers, such opinion or
      opinions, dated the Closing Date, with respect to the issuance and sale of
      the Securities, the Final Memorandum (as amended or supplemented at the
      Closing Date) and other related matters as the Representatives my
      reasonably require, and the Company shall have furnished or made available
      to such counsel such documents as they request for the purpose of enabling
      them to pass upon such matters.

            (e) The Company shall have furnished to Representatives a
      certificate of the Company, signed by any two of the following officers:
      the President, the Chief Operating Officer, the Chief Executive Officer,
      the Chief Financial Officer, the Treasurer or the General Counsel of the
      Company, dated the Closing Date, to the effect that the signers of such
      certificate have carefully reviewed the Final Memorandum, any amendment or
      supplement to the Final Memorandum and this Agreement and that:

                  (i) the representations and warranties of the Company in this
            Agreement are true and correct in all material respects on and as of
            the Closing Date with the same effect as if made on the Closing
            Date, except to the extent such representations and warranties speak
            as of an earlier date in which case they shall be true in all
            material respects as of such earlier date, and the Company has
            complied in all material respects with all the agreements and
            satisfied all the conditions on its part to be performed or
            satisfied hereunder at or prior to the Closing Date; and

                  (ii) since the date of the most recent financial statements
            included in the Final Memorandum, there has been no material adverse
            change in the condition (financial or otherwise), prospects,
            earnings, business or properties of the Company and its
            subsidiaries, taken as a whole, whether or not arising from
            transactions in the ordinary course of business, except as set forth
            in or contemplated in the Final Memorandum (exclusive of any
            amendment or supplement thereto).

            (f) (A) At the Execution Time, Arthur Andersen & Co. shall have
      furnished to the Representatives a letter dated such date, in form and
      substance satisfactory to the Initial Purchasers, containing statements
      and information of the type ordinarily included in accountants' "comfort
      letters" to underwriters with respect to the financial statements and
      certain financial information contained in the Final Memorandum and (B) at
      the Closing Date, Arthur Andersen & Co. shall have furnished to the
      Representatives a letter dated such date, in form and substance
      satisfactory to the Initial Purchasers, to the effect that they reaffirm
      the statements made in the letter furnished pursuant to clause (A) of this
      sentence, except that the specified date referred to shall be a date not
      more than three business days prior to the Closing Date.

            (g) Subsequent to the Execution Time or, if earlier, the dates as of
      which information is given in the Final Memorandum, there shall not have
      been (i) any change or decrease specified in the letters referred to in
      paragraph (e) of this Section 6 or (ii) any change, or any development
      involving a prospective change, in or affecting the condition


                                       16
<PAGE>

      (financial or otherwise), prospects, earnings, business or properties of
      the Company and its subsidiaries, taken as a whole, whether or not arising
      from transactions in the ordinary course of business, except as set forth
      or contemplated in the final Memorandum (exclusive of any amendment or
      supplement thereto), the effect of which, in any case referred to in
      clause (i) or (ii) above, is, in the sole judgment of the Representatives,
      so material and adverse as to make it impractical or inadvisable to market
      the Securities as contemplated by the Final Memorandum (exclusive of any
      amendment or supplement thereto).

            (h) The Dollar Notes shall have been designated as PORTAL-eligible
      securities in accordance with the rules and regulations of the National
      Association of Securities Dealers, Inc.

            (i) Subsequent to the Execution Time, there shall not have been any
      decrease in the rating of any of FLAG Limited's debt securities by any
      "nationally recognized statistical rating organization" (as defined for
      purposes of Rule 436(g) under the Securities Act) or any notice given of
      any intended or potential decrease in any such rating or of a possible
      change in any such rating that does not indicate the direction of the
      possible change.

            (j) Prior to the Closing Date, the Company shall have furnished to
      the Representatives such reasonable further information, certificates and
      documents as the Representatives may reasonably request.

            If any of the conditions specified in this Section 6 shall
not have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Initial Purchasers, this Agreement and all obligations of the Initial Purchasers
hereunder may be cancelled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Company in
writing, by facsimile or by telephone confirmed in writing.

            The documents required to be delivered by this Section 6 shall be
delivered at the office of counsel for the Initial Purchasers at One Liberty
Plaza, New York, New York, or such other place as the Representatives and the
Company shall mutually agree, on the Closing Date.

            7. Reimbursement of Expenses. If the sale of the Securities provided
for herein is not consummated because any condition to the obligations of the
Initial Purchasers set forth in Section 6 hereof is not satisfied, because of
any termination pursuant to Section 10(i)(A) hereof or because of any refusal,
inability or failure on the part of the Company to perform any agreement herein
or comply with any provision hereof other than by reason of a default by any of
the Initial Purchasers as described in Section 9 hereof, the Company will remain
obligated to reimburse the Initial Purchasers severally upon demand for all
reasonable and documented out-of-pocket expenses (including reasonable fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Securities.


                                       17
<PAGE>

            8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Initial Purchaser, the directors, officers,
employees and agents of each Initial Purchaser and each person who controls any
Initial Purchaser within the meaning of either the Securities Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Securities
Act, the Exchange Act or other federal or state or foreign statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
the Preliminary Memorandum, the Final Memorandum (or in any supplement or
amendment thereto) or any information provided by the Company to any holder or
prospective purchaser of Securities pursuant to Section 5(h), or in any
amendment thereof 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, in the light of the
circumstances under which they were made, not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the Company will 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 any such untrue
statement or alleged untrue statement or omission or alleged omission made in
the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof
or supplement thereto, in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any of the Initial
Purchasers through the Representatives specifically for inclusion therein; and
provided further, that the foregoing indemnity agreement with respect to the
Preliminary Memorandum shall not inure to the benefit of the Initial Purchasers
from whom the person asserting or causing any such losses, claims, damages or
liabilities purchased Securities (or to the benefit of any person controlling
any Initial Purchaser or any directors, officers, employees and agents of any
Initial Purchaser), if a copy of the Final Memorandum (or the Final Memorandum
as amended or supplemented) (if the Company shall have timely furnished the
Initial Purchasers with sufficient copies thereof) was not sent or given by or
on behalf of the Initial Purchasers to such person at or prior to the written
confirmation of the sales of the Securities to such person and if the Final
Memorandum (or the Final Memorandum as amended or supplemented) would have cured
the defect giving rise to such loss, claim, damage or liability. This indemnity
agreement will be in addition to any liability which the Company may otherwise
have.

            (b) Each Initial Purchaser severally agrees to indemnify and hold
harmless the Company, its directors, its officers, employees and agents and each
person who controls the Company within the meaning of either the Securities Act
or the Exchange Act, to the same extent as the foregoing indemnity from the
Company to each Initial Purchaser, but only with reference to written
information relating to such Initial Purchaser furnished to the Company by or on
behalf of such Initial Purchaser through the Representatives specifically for
inclusion in the Preliminary Memorandum or the Final Memorandum (or in any
amendment or supplement thereto). This indemnity agreement will be in addition
to any liability which any Initial Purchaser may otherwise have. The Company
acknowledges that the statements set forth in the last paragraph of the cover
page and under the heading "Plan of Distribution" in the Preliminary Memorandum
and the Final Memorandum constitute the only information furnished in writing by
or an behalf of the Initial Purchasers for inclusion in the Preliminary
Memorandum and the Final Memorandum (or in any amendment or supplement thereto).


                                       18
<PAGE>

            (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will notify the indemnifying party in writing of the commencement thereof; but
the failure so to notify the indemnifying party (i) will not relieve the
indemnifying party from liability under paragraph (a) or (b) above unless and to
the extent the indemnifying party did not otherwise learn of such action and
such failure results in the forfeiture by the indemnifying party of substantial
rights and defenses and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above. The
indemnifying party shall be entitled to appoint counsel of the indemnifying
party's choice at the indemnifying party's expense to represent the indemnified
party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses
of any separate counsel retained by the indemnified party or parties except as
set forth below); provided, however, that such counsel shall be satisfactory to
the indemnified party. Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the indemnified
party shall have the right to employ separate counsel (including local counsel),
and the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. No indemnifying party shall be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action,
the indemnifying party agrees to indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment. An indemnifying party will not, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

            (d) In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Initial Purchasers agree
to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Initial Purchasers may be subject in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and by the Initial Purchasers on the other from the offering of the
Securities; provided, however, that in no case shall any Initial Purchaser
(except as may be provided in any agreement among the Initial Purchasers
relating to the


                                       19
<PAGE>

offering of the Securities) be responsible for any amount in excess of the
purchase discount or commission applicable to the Securities purchased by such
Initial Purchaser hereunder. If the allocation provided by the immediately
preceding sentence is unavailable for any reason, the Company and the Initial
Purchasers shall contribute in such proportion as is appropriate to reflect not
only such relative benefits but also the relative fault of the Company on the
one hand and of the Initial Purchasers on the other in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the total net proceeds from the offering (before deducting
expenses), and benefits received by the Initial Purchasers shall be deemed to be
equal to the total purchase discounts and commissions received by the Initial
Purchasers from the Company in connection with the purchase of the Securities
hereunder, in each case as set forth on the cover of the Final Memorandum.
Relative fault shall be determined by reference to whether any untrue or any
alleged untrue statement or omission relates to information provided by the
Company on the one hand or the Initial Purchasers on the other. The Company and
the Initial Purchasers agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d) , 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. For purposes of this Section 8,
each person who controls an Initial Purchaser within the meaning of either the
Securities Act or the Exchange Act and each director, officer, employee and
agent of an Initial Purchaser shall have the same rights to contribution as such
Initial Purchaser, and each person who controls the Company within the meaning
of either the Securities Act or the Exchange Act and each director, officer,
employee, and agent of the Company shall have the same rights to contribution as
the Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

            9. Default by an Initial Purchaser. If any one or more Initial
Purchasers shall fail to purchase and pay for any of the Securities agreed to be
purchased by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Initial Purchasers) the Securities which the defaulting Initial
Purchaser or Initial Purchasers agreed but failed to purchase; provided,
however, that in the event that the aggregate principal amount of Securities
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed
to purchase shall exceed 10% of the aggregate principal amount of Securities set
forth in Schedule I hereto, the remaining Initial Purchasers shall have the
right to purchase all, but shall not be under any obligation to purchase any, of
the Securities, and if such non-defaulting Initial Purchasers do not purchase
all the Securities, this Agreement will terminate without liability to any
non-defaulting Initial Purchaser or the Company. In the event of a default by
any Initial Purchaser as set forth in this Section 9, the Closing Date shall be
postponed for such period, not exceeding seven days, as the Representatives
shall determine in order that the required changes in the Final Memorandum or in
any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Initial Purchaser of its liability, if
any, to the Company or any non-defaulting Initial Purchaser for damages
occasioned by its default hereunder.


                                       20
<PAGE>

            10. Termination. This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time (i)
(A) trading in the Company's securities shall have been suspended by the
Commission, the Nasdaq National Market or the London Stock Exchange, or trading
in securities generally on the New York Stock Exchange, the Nasdaq National
Market or the London Stock Exchange shall have been suspended or limited or (B)
minimum prices shall have been established on the New York Stock Exchange, the
Nasdaq National Market or the London Stock Exchange, (ii) a banking moratorium
shall have been declared either by federal or New York state authorities or
(iii) there shall have occurred any outbreak or escalation of hostilities,
declaration by the United States of a national emergency or war or other
calamity or crisis the effect of which on financial markets is such as to make
it, in the judgment of the Representatives, impracticable or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Final Memorandum (exclusive of any amendment or supplement thereto).

            11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Initial Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of the Initial Purchasers or the Company
or any of the officers, directors or controlling persons referred to in Section
8 hereof, and will survive delivery of and payment for the Securities. The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancellation of this Agreement.

            17. Submission to Jurisdiction; Appointment of Agents for Service;
Currency Indemnity. (a) To the fullest extent permitted by applicable law, the
Company irrevocably submits to the jurisdiction of any Federal or State court in
the Borough of Manhattan, in the City of New York, New York, in any suit, action
or proceeding based on or arising under this Agreement (solely in connection
with any such suit or proceeding), and irrevocably agrees that all claims in
respect of such suit or proceeding may be determined in any such court. The
Company irrevocably waives, to the fullest extent permitted by law, any
objection which it may have to the laying of the venue of any such suit, action
or proceeding brought in such a court and any claim that any suit, action or
proceeding brought in such a court has been brought in an inconvenient forum.
The Company agrees that final judgment in any such suit, action or proceeding
brought in such a court shall be conclusive and binding upon the Company and may
be enforced in the courts of Bermuda (or any other courts to the jurisdiction of
which the Company is subject) by a suit upon such judgment, provided that
service of process is effected upon the Company in the manner specified herein
or as otherwise permitted by law. The Company hereby irrevocably designates and
appoints FLAG Telecom USA Ltd., 570 Lexington Avenue, New York, New York 10020,
U.S.A. (the "Process Agent"), as the authorized agent of the Company upon whom
process may be served in any such suit or proceeding, it being understood that
the designation and appointment of the Process Agent as such authorized agent
shall become effective immediately without any further action on the part of the
Company. The Company represents to the Initial Purchasers that it has notified
the Process Agent of such designation and appointment and that the Process Agent
has accepted the same in writing. The Company hereby irrevocably authorizes and
directs the Process Agent to accept such service. The Company further agrees
that service of process upon the Process Agent and written notice of said
service to the Company mailed by prepaid registered first class mail or
delivered to the Process Agent at its principal office, shall be deemed in every
respect effective service of process upon the Company in any such suit or
proceeding. Nothing herein shall affect the right of the Initial Purchasers or
any person controlling the Initial Purchasers to serve process in any other
manner permitted by law. The Company further agrees to take any and all action,
including the execution and filing of any and all such documents and instruments
as may be necessary to continue such designation and appointment of the Process
Agent in full force and effect so long as the Company has any outstanding
obligations under this Agreement, the Securities or the Indentures. To the
extent that the Company has or hereafter may require any immunity from
jurisdiction of any court or from any legal process (whether through service of
note, attachment prior to judgment, attachment in aid of execution, executor or
otherwise) with respect to itself or its property, the Company hereby
irrevocably waives such immunity in respect of its obligations under this
Agreement, to the extent permitted by law.

            (b) The obligation of the parties to make payments hereunder for the
Dollar Notes is in U.S. dollars and the obligation of the parties to make
payments hereunder for the Euro Notes is in Euros (in each case, the "Obligation
Currency") and, unless otherwise agreed by the parties hereto, such obligations
shall not be discharged or satisfied by any tender or recovery pursuant to any
judgment expressed in or converted into any currency other than the applicable
Obligation Currency or any other realization in such other currency, whether as
proceeds of


                                       22
<PAGE>

set-off, security, guarantee, distributions, or otherwise, except to the extent
such tender, recovery or realization shall result in the effective receipt by
the party which is to receive such payment of the full amount of the applicable
Obligation Currency payable hereunder, and the party liable to make such payment
agrees to indemnify the party which is to receive such payment (as an
additional, separate and independent obligation) for the amount (if any) by
which such effective receipt is less than the full amount of the applicable
Obligation Currency payable hereunder and such obligation to indemnify shall not
be affected by judgment being obtained for any other sums due under this
Agreement.

            18. Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            19. Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other

            (b) Each Initial Purchaser represents, warrants and agrees that it

            (c) At any time and from time to time after the execution and
delivery of this Indenture, the Trustee shall authenticate and make available
for delivery Notes upon a written order of the Company signed by two Officers or
by an Officer and either an Assistant Treasurer or an Assistant Secretary of the
Company (the "Company Order"). A Company Order shall specify the amount of the
Notes to be authenticated and the date on which the original issue of Notes is
to be authenticated. The aggregate principal amount of Notes that may be
authenticated and delivered under this Indenture is limited to Euro 300 million.

            (d) The Trustee may appoint an agent (the "Authenticating Agent")
reasonably acceptable to the Company to authenticate the Notes. Unless limited
by the terms of such appointment, any such Authenticating Agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by the Authenticating
Agent.

            (e)  In case the Company:

            (i)  shall be consolidated with or merged into any other Person, or

            (ii)  shall convey, transfer, lease or otherwise dispose of its
      properties and assets substantially as an entirety to any Person,

and the Surviving Entity resulting from such consolidation, or surviving such
merger, or which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article IV, any of the Notes authenticated or
delivered prior to such transaction may, from time to time, at the request of
the Surviving Entity, be exchanged for other Notes executed in the name of the
Surviving Entity with such changes in phraseology and form as may be
appropriate, but otherwise identical to the Notes surrendered for such exchange
and of like principal amount; and the Trustee, upon Company Order of the
Surviving Entity, shall authenticate and deliver Notes as specified in such
order for the purpose of such exchange. If Notes shall at any time be
authenticated and delivered in any new name of a Surviving Entity pursuant to
this Section 2.2 in exchange or substitution for or upon registration of
transfer of any Notes, such Surviving Entity, at the option of the Holders but
without expense to them, shall provide for the exchange of all Notes at the time
Outstanding for Notes authenticated and delivered in such new name.

            Section 2.3.  Registrar and Paying Agent.

            (a) The Company shall maintain in the Borough of Manhattan, The City
of New York, New York or in London, England (the "Corporate Trust Office") and,
as long as the Notes are listed on the Luxembourg Stock Exchange and the rules
of The Luxembourg Stock Exchange so require, in Luxembourg, (i) offices or
agencies where the Notes may be presented for registration of transfer or for
exchange ("Registrar") and (ii) offices or agencies where the Notes may be
presented for payment ("Paying Agent"). The Company initially designates the
Trustee at its corporate trust office in the Borough of Manhattan, The City of
New York, New


                                       29
<PAGE>

York to act as Registrar and principal Paying Agent and Kredietbank SA
Luxembourgeoise as Paying Agent and co-Registrar in Luxembourg (the "Luxembourg
Paying Agent"). The Company shall also maintain a Paying Agent and Registrar in
London, England, and initially designates the Trustee at its corporate trust
office in London to act as such Paying Agent and Registrar. The Trustee, as
Registrar at its corporate trust office in the Borough of Manhattan, The City of
New York, New York or in London, England, shall keep a register of the Notes and
of their transfer and exchange (the "Note Register"). The Note Register shall be
in written form or in any other form capable of being converted into written
form within a reasonable time. The Company may appoint one or more co-registrars
and one or more additional paying agents in such other locations as it shall
determine. The term "Registrar" includes any co-registrar and the term "Paying
Agent" includes the Luxembourg Paying Agent and any additional paying agent. The
Company may at any time and from time to time authorize any Person to act as any
Agent in place of the Trustee without prior notice to any Holder. The Company
shall notify the Trustee of the name and address of any Agent not a party to
this Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Affiliates may act as Paying Agent or Registrar.

            (b) The Company shall enter into an appropriate agency agreement
with any Registrar, Paying Agent or co-Registrar not a party to this Indenture,
which shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of each such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.7. The
Company may act as Paying Agent, Registrar, co-Registrar or transfer agent.

            (c)  The Company initially appoints The Bank of New York (Nominees),
Ltd., as common depositary (the "Depositary") for Euroclear and Clearstream,
Luxembourg to act as Depositary with respect to the Global Notes.

            Section 2.4. Paying Agent to Hold Money in Trust. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that such
Paying Agent shall hold in trust for the benefit of Holders or the Trustee all
money held by such Paying Agent for the payment of principal of or interest on
the Notes and shall notify the Trustee in writing of any default by the Company
in making any such payment. If the Company or an Affiliate of the Company acts
as Paying Agent, it shall segregate the money held by it as Paying Agent and
hold it as a separate trust fund. The Company at any time may require a Paying
Agent (other than the Trustee) to pay all money held by it to the Trustee and to
account for any funds disbursed by such Paying Agent. Upon complying with this
Section 2.4, the Paying Agent (if other than the Company) shall have no further
liability for the money delivered to the Trustee. Upon any proceeding under any
Bankruptcy Law with respect to the Company or any Affiliate of the Company, if
the Company or such Affiliate is then acting as Paying Agent, the Trustee shall
replace the Company or such Affiliate as Paying Agent.

            Section 2.5. Holder Lists. The Trustee shall preserve in as current
a form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, or to the
extent otherwise required under the TIA, the Company shall furnish to the
Trustee, in writing at least seven Business Days before each


                                       30
<PAGE>

Interest Payment Date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Holders.

            Section 2.6.  Global Note Provisions.

            (a) Each Global Note initially shall: (i) be registered in the name
of the Depositary or the nominee of the Depositary, (ii) be delivered to the
Note Custodian, and (iii) bear the appropriate legend, as set forth in Section
2.7 and Exhibit A. Any Global Note may be represented by more than one
certificate. The aggregate principal amount of each Global Note may from time to
time be increased or decreased by adjustments made on the records of the Note
Custodian, as provided in this Indenture.

            (b) Members of, or participants in, Euroclear or Clearstream
Luxembourg ("Agent Members") shall have no rights under this Indenture with
respect to any Global Note held on their behalf by the Depositary or by the Note
Custodian under such Global Note, and the Depositary may be treated by the
Company, the Trustee, the Paying Agent and the Registrar and any of their agents
as the absolute owner of such Global Note for all purposes whatsoever (except
with respect to determination of Additional Amounts). Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee, the Paying
Agent or the Registrar or any of their agents from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or
impair, as between Euroclear or Clearstream Luxembourg and its Agent Members,
the operation of customary practices of such clearing system governing the
exercise of the rights of an owner of a beneficial interest in any Global Note.
The registered Holder of a Global Note may grant proxies and otherwise authorize
any person, including Agent Members and persons that may hold interests through
Agent Members, to take any action that a Holder is entitled to take under this
Indenture or the Notes.

            (c) Except as provided below, owners of beneficial interests in
Global Notes will not be entitled to receive Certificated Notes. Certificated
Notes shall be issued to all owners of beneficial interests in a Global Note in
exchange for such interests if:

            (i) Euroclear or Clearstream Luxembourg notifies the Company that it
      is unwilling or unable to continue as depositary for such Global Note, and
      a successor depositary is not appointed by the Company within 90 days of
      such notice,

            (ii) the Company executes and delivers to the Trustee and Registrar
      an Officers' Certificate stating that such Global Note shall be so
      exchangeable, or

            (iii)  an Event of Default has occurred and is continuing.

In connection with the exchange of an entire Global Note for Certificated Notes
pursuant to this paragraph (c), such Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
upon Company Order the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in such Global Note, an equal aggregate principal amount of
Certificated Notes of authorized denominations.


                                       31
<PAGE>

            (d) In the event of the occurrence of the events specified in
Section 2.6(c), the Company will promptly make available to the Trustee a
reasonable supply of certificated Notes in definitive, fully registered form
without interest coupons.

            Section 2.7.  Legends.

            (a) Each Global Note shall bear the legend specified therefor in
Exhibit A on the face thereof.

            (b) Each Restricted Note shall bear the private placement legend
specified therefor in Exhibit A on the face thereof (together with, if
applicable, the legend specified in paragraph (c) of this Section 2.7, the
"Private Placement Legend").

            (c) Each Certificated Note that is a Restricted Note shall bear the
legend specified therefor in Exhibit A on the face thereof.

            Section 2.8.  Transfer and Exchange.

            (a) If (1) the owner of a beneficial interest in a Rule 144A Global
Note that is a Restricted Note wishes to transfer such interest (or portion
thereof) to a Non-U.S. Person pursuant to Regulation S and (2) such Non-U.S.
Person wishes to hold its interest in the Notes through a beneficial interest in
the Regulation S Global Note, (x) upon receipt by the Note Custodian and
Registrar of:

      (A) instructions from the Holder of the Rule 144A Global Note directing
      the Note Custodian and Registrar to credit or cause to be credited a
      beneficial interest in the Regulation S Global Note equal to the principal
      amount of the beneficial interest in the Rule 144A Global Note to be
      transferred, and

      (B)  a certificate in the form of Exhibit C from the transferor,


                                       32
<PAGE>

and (y) subject to the rules and procedures of Euroclear or Clearstream
Luxembourg, the Note Custodian and Registrar shall increase the Regulation S
Global Note and decrease the Rule 144A Global Note by such amount in accordance
with the foregoing.

            (b) If the owner of an interest in a Regulation S Global Note wishes
to transfer such interest (or any portion thereof) to a QIB pursuant to Rule
144A prior to the expiration of the Distribution Compliance Period therefor, (x)
upon receipt by the Note Custodian and Registrar of:

      (A) instructions from the Custodian and Holder of the Regulation S Global
      Note directing the Note Registrar to credit or cause to be credited a
      beneficial interest in the Rule 144A Global Note equal to the principal
      amount of the beneficial interest in the Regulation S Global Note to be
      transferred, and

      (B)  a certificate in the form of Exhibit B duly executed by the
      transferor,

and (y) in accordance with the rules and procedures of Euroclear or Clearstream
Luxembourg, the Note Custodian and Registrar shall increase the Rule 144A Global
Note and decrease the Regulation S Global Note by such amount in accordance with
the foregoing.

            (c) Other Transfers. Any transfer of Restricted Notes not described
above (other than a transfer of a beneficial interest in a Global Note that does
not involve an exchange of such interest for a Certificated Note or a beneficial
interest in another Global Note, which must be effected in accordance with
applicable law and the rules and procedures of Euroclear or Clearstream
Luxembourg, but is not subject to any procedure required by this Indenture)
shall be made only upon receipt by the Registrar of such opinions of counsel,
certificates and/or other information reasonably required by and satisfactory to
it in order to ensure compliance with the Securities Act or in accordance with
paragraph (d) of this Section 2.8.

            (d) Use and Removal of Private Placement Legends. Upon the transfer,
exchange or replacement of Notes (or beneficial interests in a Global Note) not
bearing a Private Placement Legend, the Note Custodian and Registrar shall
exchange such Notes (or beneficial interests) for beneficial interests in a
Global Note (or Certificated Notes if they have been issued pursuant to Section
2.6(c)) that does not bear a Private Placement Legend. Upon the transfer,
exchange or replacement of Notes (or beneficial interests in a Global Note)
bearing a Private Placement Legend, the Note Custodian and Registrar shall
deliver only Notes (or beneficial interests in a Global Note) that bear a
Private Placement Legend unless:

            (i) such Notes (or beneficial interests) are exchanged in a
      Registered Exchange Offer;

            (ii) such Notes (or beneficial interests) are transferred pursuant
      to a Registration Statement;

            (iii) such Notes (or beneficial interests) are transferred pursuant
      to Rule 144 upon delivery to the Registrar of a certificate of the
      transferor in the form of Exhibit D and an Opinion of Counsel reasonably
      satisfactory to the Registrar;

            (iv) such Notes (or beneficial interests) are transferred, replaced
      or exchanged after the Resale Restriction Termination Date therefor; or

            (v) in connection with such transfer, exchange or replacement the
      Registrar shall have received an Opinion of Counsel and other evidence
      reasonably satisfactory to it to the effect that neither such Private
      Placement Legend nor the related restrictions on transfer are required in
      order to maintain compliance with the provisions of the Securities Act.

The Private Placement Legend on any Note shall be removed at the request of the
Holder on or after the Resale Restriction Termination Date therefor. The Holder
of a Global Note may exchange an interest therein for an equivalent interest in
a Global Note not bearing a Private Placement Legend (other than a Regulation S
Global Note) upon transfer of such interest pursuant to any of clauses (i)
through (v) of this paragraph (e). The Company shall deliver to the Trustee an
Officers' Certificate promptly upon effectiveness, withdrawal or suspension of
any Registration Statement.

            (e) Consolidation of Global Notes and Exchange of Certificated Notes
for Beneficial Interests in Global Notes. If a Global Note not bearing a Private
Placement Legend (other than a Regulation S Global Note) is Outstanding at the
time of a Registered Exchange Offer, any interests in a Global Note exchanged in
such Registered Exchange Offer shall be exchanged for interests in such
Outstanding Global Note.

            (f) Retention of Documents. The Registrar shall retain copies of all
letters, notices and other written communications received pursuant to this
Article II. The Company shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
upon the giving of reasonable written notice to the Registrar.

            (g)  Execution, Authentication of Notes, etc.

                  (i) Subject to the other provisions of this Section 2.8, when
      Notes are presented to the Registrar or a co-Registrar with a request to
      register the transfer of such Notes or to exchange such Notes for an equal
      principal amount of Notes of other authorized denominations, the Registrar
      or co-Registrar shall register the transfer or make the exchange as
      requested if its requirements for such transaction are met; provided that
      any Notes presented or surrendered for registration of transfer or
      exchange shall be duly endorsed or accompanied by a written instrument of
      transfer in form satisfactory to the Registrar or co-Registrar, duly
      executed by the Holder thereof or his attorney duly authorized in writing.
      To permit registrations of transfers and exchanges and subject to the
      other terms and conditions of this Article II, the Company will execute
      and upon Company Order the Trustee will authenticate Certificated Notes
      and Global Notes at the Registrar's or co-Registrar's request. In
      accordance with the Registration Agreement, the Company will execute and
      upon Company Order the Trustee will authenticate Exchange Notes or Private
      Exchange Notes, as the case may be in exchange for Notes.

                  (ii) No service charge shall be made to a Holder for any
      registration of transfer or exchange, but the Company may require payment
      of a sum sufficient to cover any transfer tax, assessments, or similar
      governmental charge payable in connection therewith (other than any such
      transfer taxes, assessments or similar governmental charges payable upon
      exchange or transfer pursuant to a Registered Exchange Offer, or Sections
      5.1, 3.8, 3.15 or 9.5).

                  (iii) The Registrar or co-Registrar shall not be required to
      register the transfer of or exchange of any Note for a period beginning:
      (1) 15 days before the mailing of a notice of an offer to repurchase or
      redeem Notes and ending at the close of business on the day of such
      mailing or (2) 15 days before an Interest Payment Date and ending on such
      Interest Payment Date.

                  (iv) Prior to the due presentation for registration of
      transfer of any Note, the Company, the Trustee, the Paying Agent, the
      Registrar or any co-Registrar may deem and treat the person in whose name
      a Note is registered as the absolute owner of such Note for the purpose of
      receiving payment of principal of and interest on such Note and for all
      other purposes whatsoever, whether or not such Note is overdue, and none
      of the


                                       34
<PAGE>

      Company, the Trustee, the Paying Agent, the Registrar or any co-Registrar
      shall be affected by notice to the contrary.

                  (v) All Notes issued upon any transfer or exchange pursuant to
      the terms of this Indenture shall evidence the same debt and shall be
      entitled to the same benefits under this Indenture as the Notes
      surrendered upon such transfer or exchange.

            (h)  No Obligation of the Trustee.

                  (i) The Trustee shall have no responsibility or obligation to
      any beneficial owner of interest in a Global Note, a member of, or a
      participant in, Euroclear or Clearstream Luxembourg or other Person with
      respect to the accuracy of the records of Euroclear or Clearstream
      Luxembourg or its nominee or of any participant or member thereof, with
      respect to any ownership interest in the Notes or with respect to the
      delivery to any participant, member, beneficial owner or other Person
      (other than the Depositary, Euroclear or Clearstream Luxembourg) of any
      notice (including any notice of redemption) or the payment of any amount
      or delivery of any Notes (or other security or property) under or with
      respect to such Notes. All notices and communications to be given to the
      Holders and all payments to be made to Holders in respect of the Notes
      shall be given or made only to or upon the order of the registered Holders
      (which shall be the Depositary, Euroclear or Clearstream Luxembourg or its
      nominee in the case of a Global Note). The Trustee may rely and shall be
      fully protected in relying upon information furnished by Euroclear or
      Clearstream Luxembourg with respect to its members, participants and any
      beneficial owners.

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

            Section 2.9.  Mutilated, Destroyed, Lost or Stolen Notes.

            (a) If a mutilated Note is surrendered to the Registrar or if the
Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall execute and upon Company Order the Trustee shall
authenticate a replacement Note if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such
Holder shall furnish an affidavit of loss and indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-Registrar from any loss that any of them
may suffer if a Note is replaced, and, in the absence of notice to the Company
or the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
make


                                       35
<PAGE>

available for delivery, in exchange for any such mutilated Note or in lieu
of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, bearing a number not contemporaneously Outstanding.

            (b) Upon the issuance of any new Note under this Section 2.9, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

            (c) Every new Note issued pursuant to this Section 2.9 in exchange
for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, shall
constitute an original additional contractual obligation of the Company and any
other obligor upon the Notes, whether or not the mutilated, destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

            Section 2.10. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may execute and upon Company Order the Trustee will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of definitive Notes but may have variations that the Company considers
appropriate for temporary Notes. Without unreasonable delay, the Company will
prepare and execute and upon Company Order the Trustee will authenticate
definitive Notes. After the preparation of definitive Notes, the temporary Notes
will be exchangeable for definitive Notes upon surrender of the temporary Notes
at any office or agency maintained by the Company for that purpose and such
exchange shall be without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Notes, the Company will execute and upon Company
Order the Trustee will authenticate and make available for delivery in exchange
therefor one or more definitive Notes representing an equal principal amount of
Notes. Until so exchanged, the Holder of temporary Notes shall in all respects
be entitled to the same benefits under this Indenture as a Holder of definitive
Notes.

            Section 2.11. Cancellation. The Company at any time may deliver
Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee, the Paying Agent and no one else
shall cancel and dispose of cancelled Notes in accordance with its policy of
disposal or return to the Company or to the Trustee all Notes surrendered for
registration of transfer, exchange, payment or cancellation. The Company may not
issue new Notes to replace Notes it has paid or delivered to the Trustee for
cancellation for any reason other than in connection with a transfer or exchange
upon Company Order.

            Section 2.12. Defaulted Interest. When any installment of interest
becomes Defaulted Interest, such installment shall forthwith cease to be payable
to the Holders in whose names the Notes were registered on the Record Date
applicable to such installment of interest. Defaulted Interest (including any
interest on such Defaulted Interest) may be paid by the Company, at its
election, as provided in clause (A) or (B) below.

            (A) The Company may elect to make payment of any Defaulted Interest
      (including any interest on such Defaulted Interest) to the Holders in
      whose names the


                                       36
<PAGE>

      Notes are registered at the close of business on a special record date for
      the payment of such Defaulted Interest (a "Special Record Date"), which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      and the date of the proposed payment, and at the same time the Company
      shall deposit with the Trustee an amount of money equal to the aggregate
      amount proposed to be paid in respect of such Defaulted Interest or shall
      make arrangements satisfactory to the Trustee for such deposit prior to
      the date of the proposed payment, such money when deposited to be held in
      trust for the benefit of the Holders entitled to such Defaulted Interest
      as provided in this clause (A). Thereupon the Trustee shall fix a Special
      Record Date for the payment of such Defaulted Interest, which shall be not
      more than 15 calendar days and not less than ten calendar days prior to
      the date of the proposed payment and not less than ten calendar days after
      the receipt by the Trustee of the notice of the proposed payment. The
      Trustee shall promptly notify the Company of such Special Record Date and,
      in the name and at the expense of the Company, shall cause notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor to be sent, first-class mail, postage prepaid, to each Holder at
      such Holder's address as it appears in the registration books of the
      Registrar, not less than ten calendar days prior to such Special Record
      Date. Notice of the proposed payment of such Defaulted Interest and the
      Special Record Date therefor having been mailed as aforesaid, such
      Defaulted Interest shall be paid to the Holders in whose names the Notes
      are registered at the close of business on such Special Record Date and
      shall no longer be payable pursuant to the following clause (B).

            (B) Alternatively, the Company may make payment of any Defaulted
      Interest (including any interest on such Defaulted Interest) in any other
      lawful manner not inconsistent with the requirements of any securities
      exchange on which the Notes may be listed, and upon such notice as may be
      required by such exchange, if, after notice given by the Company to the
      Trustee of the proposed payment pursuant to this clause (B), such manner
      of payment shall be deemed practicable by the Trustee.

            Section 2.13. Additional Interest Under Registration Agreements.
Under certain circumstances, the Company may be obligated to pay additional
interest to Holders, all as and to the extent set forth in the Registration
Agreement. The terms thereof are hereby incorporated herein by reference and
such additional interest is deemed to be interest for purposes of this
Indenture.

            Section 3.1.  Payment of Notes.

            (a) The Company shall pay the principal of and interest (including
Defaulted Interest) on the Notes in Euros on the dates and in the manner
provided in the Notes and in this Indenture. Prior to 10:00 a.m. (London,
England time) two business days before the date on which any principle of or
interest on any Note is due and payable, the Company shall irrevocably deposit
with the Trustee or the Paying Agent in immediately available funds Euros
sufficient


                                       37
<PAGE>

to make cash payments due on such Interest Payment Date or Maturity
Date, as the case may be. If the Company or an Affiliate of the Company is
acting as Paying Agent, the Company or such Affiliate shall, prior to 10:00 a.m.
on each Interest Payment Date and the Maturity Date, segregate and hold in trust
Euros sufficient to make cash payments due on such Interest Payment Date or
Maturity Date, as the case may be. Principal and interest shall be considered
paid on the date due if on such date the Trustee or the Paying Agent (other than
the Company or an Affiliate of the Company) holds in accordance with this
Indenture Euros designated for and sufficient to pay all principal and interest
then due and the Trustee or the Paying Agent, as the case may be, is not
prohibited from paying such money to the Holders on that date pursuant to the
terms of this Indenture.

            (b) Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United States of
America from principal or interest payments hereunder.

            Section 3.2.  Maintenance of Office or Agency.

            (a) The Company shall maintain each office or agency required under
Section 2.3. The Company will give prompt written notice to the Trustee of any
change in the location of any such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

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

            (c) In addition, the Company shall maintain in London, England, an
office or agency where Notes may be presented or surrendered for payment. So
long as the Notes are listed on the Luxembourg Stock Exchange and the rules of
the Luxembourg Stock Exchange so require, the Company shall maintain an agent
for making payments on, and transfers of, Notes in Luxembourg.

            Section 3.3. Corporate Existence. Subject to Article IV, the Company
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence.

            Section 3.4. Payment of Taxes and Other Claim. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all


                                       38
<PAGE>

taxes, assessments and governmental charges levied or imposed upon the Company
or any Restricted Subsidiary or for which it or any of them are otherwise
liable, or upon the income, profits or property of the Company or any Restricted
Subsidiary and (ii) all lawful claims for labor, materials and supplies, which,
if unpaid, might by law become a liability or Lien upon the property of the
Company or any Restricted Subsidiary; provided, however, that the Company shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings and for which
appropriate reserves, if necessary (in the good faith judgment of management of
the Company), are being maintained in accordance with U.S. GAAP or where the
failure to effect such payment will not be disadvantageous to the Holders.

            Section 3.5. Compliance Certificate. (a) The Company shall deliver
to the Trustee within 90 days after the end of each fiscal year of the Company,
commencing with fiscal year 2000, an Officers' Certificate stating that in the
course of the performance by the signers of their duties as Officers of the
Company they would normally have knowledge of any Default or Event of Default
and whether or not the signers know of any Default or Event of Default that
occurred during such period. If they do, the certificate shall describe the
Default or Event of Default, its status and what action the Company is taking or
proposes to take with respect thereto. The Company also shall comply with TIA
ss. 314(a)(4).

            (b) So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants or to the policies of the
Company's independent accountants, the annual Officers' Certificate delivered
pursuant to this Section 3.5 to the Trustee shall be accompanied by a written
report of the Company's independent accountants (who shall be a firm of
established national reputation) that in conducting their audit of the financial
statements of the Company for the most recent fiscal year nothing has come to
their attention that would lead them to believe that a Default or Event of
Default under this Indenture has occurred insofar as they relate to accounting
matters or, if any such violation has occurred, specifying the nature and period
of existence thereof, it being understood that such accountants shall not be
liable directly or indirectly to any Person for any failure to obtain knowledge
of any such violation that would not be disclosed in the course of an audit
examination conducted in accordance with U.S. GAAP.

            Section 3.6. Further Instruments and Acts. The Company will execute
and deliver such further instruments and do such further acts as may be
reasonably necessary or proper or as the Trustee may reasonably request to carry
out more effectively the purpose of this Indenture.

            Section 3.7. Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other law that
would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Notes as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture. The Company hereby expressly waives (to the
extent that it may lawfully do so) all benefit or advantage of any such law, and
covenants that it will not hinder, delay or impede


                                       39
<PAGE>

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.

            Section 3.8.  Change Of Control.

            (a) Upon the occurrence of a Change of Control, each Holder of Notes
will have the right to require that the Company purchase all or a portion (in
integral multiples of Euro 1,000) of the Holder's Notes at a purchase price
equal to 101% of the principal amount thereof, plus accrued and unpaid interest
through the date of purchase (the "Change of Control Payment").

            (b) Within 30 days following the date upon which the Change of
Control occurred, the Company must send a Change of Control Notice to each
Holder of Notes, with a copy to the Trustee, offering to purchase such Notes as
described above (a "Change of Control Offer"). The Change of Control Offer shall
state, among other things, the purchase date, which must be no earlier than 30
days nor later than 60 days from the date the notice is mailed, other than as
may be required by law (the "Change of Control Payment Date").

            (c)  On the Change of Control Payment Date, the Company will, to the
extent lawful:

            (1) accept for payment all Notes or portions thereof properly
      tendered pursuant to a Change of Control Offer (or, if the Trustee is
      acting as agent for the Company, direct the Trustee to so accept);

            (2) deposit with the Paying Agent funds in an amount equal to the
      Change of Control Payment in respect of all Notes or portions thereof so
      tendered; and

            (3) deliver or cause to be delivered to the Trustee (including by
      designating the Trustee as its agent for acceptance of Notes) the Notes so
      accepted together with an Officers' Certificate stating the aggregate
      principal amount of Notes or portions thereof being purchased by the
      Company.

            (d) If only a portion of a Note is purchased pursuant to a Change of
Control Offer, a new Note in a principal amount equal to the portion thereof not
purchased will be issued in the name of the Holder thereof upon cancellation of
the original Note (or appropriate adjustments to the amount and beneficial
interests in the applicable Global Note will be made, as appropriate).

            (e) The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other applicable securities laws and regulations
in connection with the purchase of Notes in connection with any Change of
Control Offer. To the extent that the provisions of any securities laws or
regulations conflict with this Section 3.8, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under such Indenture by doing so.

            Section 3.9.  Additional Amounts.


                                       40

      thereof or therein having power to tax,

            (2) any jurisdiction, other than the United States, the United

subdivision or taxing authority) in respect of any amounts to be paid by the
Company or a successor corporation under the Notes, the Company or a successor
corporation will pay each holder of such a Note as additional interest, such
additional amounts ("Additional Amounts") as may be necessary in order that the
net amounts paid to such Holder who, with respect to any such tax, assessment or
other governmental charge, is not resident in, or a citizen of, such
jurisdiction, after deduction or withholding, shall be not less than the amount
specified in such Note to which such Holder is entitled; provided, however, the
Company or a successor corporation shall not be required to make any payment of
Additional Amounts for or on account of:

            (i) any tax, 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,

      taxing jurisdiction or any political subdivision or territory or

      mere receipt of such payment or the ownership or holding of such Note),
      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,

      addressed to the Holder:

            (x)   to provide information, documents or other evidence concerning

                  beneficial owner; or

            (y)   to make and deliver any declaration or other similar claim
                  (other than a claim for refund of a tax, assessment or other
                  governmental charge withheld by the Company) or satisfy any
                  information or reporting requirements,

which, in the case of (x) or (y), is required or imposed by a statute, treaty,
regulation or administrative practice of the taxing jurisdiction as a
precondition to exemption from all or part of such tax, assessment or other
governmental charge; 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 premium or interest on, any Note to any Holder who is a fiduciary or
partnership or limited liability company or other than the sole beneficial owner
of such payment to the extent such payment would be required by the laws of:

            (1)  Bermuda or any political subdivision or governmental authority
      thereof or therein having the power to tax;

            (2) any jurisdiction, other than the United States, the United
      Kingdom or Luxembourg, from or through which payment on the Notes is made
      by the Company or a successor corporation, or its paying agent in its
      capacity as such, or any political subdivision or governmental authority
      thereof or therein having the power to tax; or

            (3) any other jurisdiction, other than the United States, in which

      subdivision or governmental authority having the power to tax

to be included in the income for tax purposes of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership or limited liability
company or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the holder of such Note.

            (b) The Company shall provide the Trustee with the official
acknowledgment of the relevant taxing authority (or, if such acknowledgment is
not available, a certified copy thereof) evidencing the payment of the
withholding taxes, if any, by the Company. Copies of


                                       42
<PAGE>

such documentation shall be made available to the holders of the Notes or the
Paying Agents, as applicable, upon request therefor.

            Section 3.10. Limitation On Incurrence Of Additional Indebtedness

      or the Company of any Indebtedness so Incurred to a Person other than the
      Company or another Restricted Subsidiary or (y) if for any reason a
      Restricted Subsidiary that is either an issuer or lender of such
      Indebtedness ceases to be a Restricted Subsidiary, the provisions of this
      clause (b) shall no longer be applicable to such Indebtedness); provided

      subordinated in all respects to the Company's obligations pursuant to the

      in respect of Indebtedness that is permitted by the terms of the relevant
      Indenture to be outstanding; provided that the notional amount of any such

      such Hedging Obligation relates;

            (g) Indebtedness of the Company or any Restricted Subsidiary solely

            (3) For purposes of determining compliance with, and the outstanding
principal amount of any particular Indebtedness Incurred pursuant to, and in
compliance with, this covenant, the amount of Indebtedness issued at a price
that is less than the principal amount thereof will be equal to the amount of
the liability in respect thereof determined in accordance with U.S. GAAP.
Accrual of interest, the accretion or amortization of original issue discount,
the payment of regularly scheduled interest in the form of additional
Indebtedness of the same instrument or the payment of regularly scheduled
dividends on Disqualified Stock in the form of additional Disqualified Stock
with the same terms will not be deemed to be an Incurrence of Indebtedness for
purposes of this Section 3.10.

            (4) The Company will not, directly or indirectly, Incur any
Indebtedness that is subordinate in right of payment to any other Indebtedness,
unless such Indebtedness is expressly subordinate in right of payment to the
Notes to the same extent and on the same terms as such Indebtedness is
subordinate to such other Indebtedness.

            (y) that portion of the Fair Market Value of the net assets of such
            Unrestricted Subsidiary at the time of such Revocation that is
            proportionate to the Company's equity interest in such Unrestricted
            Subsidiary at the time of the Revocation; and

            (z) the Designation Amount with respect to such Unrestricted
            Subsidiary upon its Designation which was treated as a Restricted
            Payment plus any Investment made after Designation and prior to
            Revocation that was treated as a Restricted Payment, in each case
            less any amounts included in clause (A) or (C) above.

            Notwithstanding the preceding, this Section 3.11 does not prohibit:

            (1) the payment of any dividend within 60 days after the date of
      declaration of such dividend if the dividend would have been permitted on
      the date of declaration;

            (2)  if no Default or Event of Default shall have occurred and be
      continuing, the acquisition of any shares of Capital Stock of the Company,

            (a)  in exchange for Qualified Capital Stock of the Company, or

            (b) through the application of the net cash proceeds received by the
Company from a substantially concurrent sale of Qualified Capital Stock of the
Company or a contribution to the equity capital of the Company not representing
an interest in Disqualified Capital Stock, in each case not received from a
Subsidiary of the Company; provided, that the value of any such Qualified
Capital Stock issued in exchange for such acquired Capital Stock and any such
net cash proceeds shall be excluded from clause (3)(B) of the first paragraph of
this Section 3.11;

            (3) if no Default or Event of Default shall have occurred and be
continuing, the voluntary prepayment, purchase, defeasance, redemption or other
acquisition or retirement for value of any Subordinated Indebtedness solely in
exchange for, or through the application of net cash proceeds of a substantially
concurrent sale, other than to a Subsidiary of the Company, of:

            (x)  Qualified Capital Stock of the Company, or

            (y)  Permitted Refinancing Indebtedness for such Subordinated
Indebtedness;

provided, that the value of any Qualified Capital Stock issued in exchange for
Subordinated Indebtedness and any net cash proceeds referred to above shall be
excluded from clause (3)(B) of the first paragraph of this Section 3.11;

            (4) the payment of any dividend or other distribution by a

for value of any Capital Stock (other than Disqualified Stock) of the Company or
any of its Restricted Subsidiaries held by any member of the Company's or such

exceed $5 million in any fiscal year (with unused amounts being carried over to
succeeding fiscal years, subject to a maximum of $10 million in any fiscal
year);

            (6)  Investments in any Permitted Joint Venture; and

            (7) Investments in any Person engaged, except to a de minimis
extent, in a Telecommunications Business, the aggregate Fair Market Value of
which (measured on the date each such Investment was made or returned, as
applicable), when taken together with all other Investments made pursuant to
this clause (7) that are at any time outstanding, does not exceed the sum of:

            (x)  $50 million, plus

            (y) the amount then available for the making of Restricted Payments
pursuant to clause (3) of the preceding paragraph without giving effect to
subclause (A) thereof.


                                       47
<PAGE>

            Each Restricted Payment permitted pursuant to clauses (1), (4), (5),
(6) and (7) of this paragraph shall be included, and each Restricted Payment
permitted pursuant to clauses (2) and (3) of this paragraph shall be excluded
(except as specifically set forth in each such clause), for all purposes when
performing the calculation set forth in clause (3) of the first paragraph of
this Section 3.11.

            Section 3.12. Limitation on Designation of Unrestricted
Subsidiaries.

            (a) The Board of Directors may not designate a Subsidiary of the
Company (other than a newly created Subsidiary in which no Investment has
previously been made (other than any de minimus amount required to capitalize
such Subsidiary in connection with its organization)) as an Unrestricted
Subsidiary (a "Designation") if:

            (1) a Default or Event of Default shall have occurred and be
      continuing at the time of or after giving effect to such Designation, and

            (2) the Company would be prohibited under this Indenture from making
      a Restricted Investment at the time of such Designation (assuming the
      effectiveness of such Designation for purposes of this Section 3.12) in an
      amount equal to the Designation Amount (as defined below).

            (b) Any Designation shall be made by Board Resolution. In the event
of any such Designation, all outstanding Investments owned by the Company and
its Restricted Subsidiaries in the Subsidiary at Designation will be deemed to
be a Restricted Investment made as of the time of such Designation and will
reduce the amount available for Restricted Payments under the first or second
paragraph of this Section 3.12. All such outstanding Investments will be deemed
to constitute Restricted Payments in an amount equal to the Fair Market Value of
such Investments at the time of such Designation (the "Designation Amount").

            (c) A Designation may be revoked and an Unrestricted Subsidiary may
thus be redesignated as a Restricted Subsidiary (a "Revocation") by Board
Resolution, provided that the Company will not make any Revocation unless after
giving pro forma effect to such Revocation:

            (1)  no Default or Event of Default shall have occurred and be
      continuing;

            (2) all Liens of such Unrestricted Subsidiary outstanding
      immediately following such Revocation would, if Incurred at such time,
      have been permitted to be Incurred at such time for all purposes under
      this Indenture; and

            (3) the Company could Incur $1 of additional Indebtedness pursuant
      to clause (1) Section 3.10.

            (d) Neither the Company nor any Restricted Subsidiary will at any
      time:

            (1) provide credit support for, subject any of its property or
      assets (other than the Capital Stock of any Unrestricted Subsidiary) to
      the satisfaction of, or guarantee, any Indebtedness of any Unrestricted
      Subsidiary (including any undertaking, agreement or instrument evidencing
      such Indebtedness);


                                       48
<PAGE>

            (2) be directly or indirectly liable for any Indebtedness of any
      Unrestricted Subsidiary; or

            (3) be directly or indirectly liable for any Indebtedness which
      provides that the holder thereof may (upon notice, lapse of time or both)
      declare a default thereon or cause the payment thereof to be accelerated
      or payable prior to its final scheduled maturity upon the occurrence of a
      default with respect to any Indebtedness of any Unrestricted Subsidiary,
      except for any non-recourse guarantee given solely to support the pledge
      by the Company or any Restricted Subsidiary of the Capital Stock of any
      Unrestricted Subsidiary.

            Section 3.13. Limitation on Liens.

            The Company will not, and will not cause or permit any Restricted
Subsidiary to, directly or indirectly, Incur or suffer to exist or become
effective any Liens of any kind (except for Permitted Liens) against or upon any
of their respective properties or assets, whether owned on the Issue Date or
acquired after the Issue Date, or any income, profits or proceeds therefrom,
unless contemporaneously therewith effective provision is made by the Company to
secure the Notes and all other amounts due under the relevant Indenture equally
and ratably with such Indebtedness with a Lien on the same properties and assets
securing such Indebtedness for so long as such Indebtedness is secured by such
Lien; provided, that no such Lien may secure Subordinated Indebtedness except as
permitted by clause 3(a) of the definition of "Permitted Liens."

            Section 3.14. Limitation On Dividend And Other Payment Restrictions
Affecting Restricted Subsidiaries.

            (a) Except as provided in clause (b) below, the Company will not,
and will not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or permit to exist or become effective any
encumbrance or restriction on the ability of any Restricted Subsidiary to:

            (1) pay dividends or make any other distributions on or in respect
      of its Capital Stock or with respect to any other interest or
      participation, or measured by its profits, to the Company or any other
      Restricted Subsidiary or pay any Indebtedness owed to the Company or any
      other Restricted Subsidiary;

            (2) make loans or advances to, or guarantee any Indebtedness or
      other obligations of, or make any Investment in, the Company or any other
      Restricted Subsidiary; or

            (3) transfer any of its property or assets to the Company or any
      other Restricted Subsidiary.

            (b) Clause (a) will not apply to encumbrances or restrictions
      existing under or by reason of:

            (1) Existing Indebtedness as in effect on the Issue Date;


                                       49
<PAGE>

            (2) this Indenture and the Notes;

            (3) any Permitted Credit Facility or Vendor Facility, provided that:

            (a) the outstanding Indebtedness under such Permitted Credit
Facility or Vendor Facility does not exceed the amounts permitted under clause
2(d) or 2(e)(y), as the case may be, of Section 3.10, and

            (b) the Chief Financial Officer of the Company determines in good
      faith that:

            (x) such encumbrances or restrictions are no more restrictive, taken
      as a whole, than those that would be contained in a credit agreement with
      terms that are commercially reasonable for a borrower engaged in a
      business comparable to the Company that has substantially comparable
      Indebtedness, and

            (y) any such restrictions will not materially affect the Company's
      ability to make principal, premium or interest payments on the Notes
      pursuant to the terms of this Indenture,

            (4) applicable law,

            (5) any instrument governing Indebtedness or Capital Stock of a
      Person or assets acquired by the Company or any of its Restricted
      Subsidiaries as in effect at the time of such acquisition (except to the
      extent such Indebtedness was Incurred in connection with or in
      contemplation of such acquisition), which encumbrances or restrictions are
      not applicable to any Person, or the properties or assets of any Person,
      other than the Person, or the property or assets of the Person, so
      acquired, provided that any such Indebtedness or Preferred Stock was
      permitted by the terms of this Indenture to be incurred,

            (6) customary non-assignment provisions in leases entered into in
      the ordinary course of business and consistent with past practices,

            (7) any agreement for the sale or other disposition of a Restricted
      Subsidiary that restricts distributions by that Restricted Subsidiary
      pending its sale or other disposition, provided that the consummation of
      such transaction would not result in a Default or Event of Default, that
      such restriction terminates if such transaction is not consummated and
      that the consummation or abandonment of such transaction occurs within one
      year of the date such agreement was entered into,

            (8) Permitted Refinancing Indebtedness, provided that the
      restrictions contained in the agreements governing such Permitted
      Refinancing Indebtedness are no more restrictive, taken as a whole, than
      those contained in the agreements governing the Indebtedness being
      Refinanced,

            (9) limitations on the right to dispose of assets subject to a Lien
      securing Indebtedness to the extent that such Lien is permitted to be
      Incurred pursuant to Section 3.13, and


                                       50
<PAGE>

            (10) provisions with respect to the disposition or distribution of
      assets or property in joint venture agreements and other similar
      agreements entered into in the ordinary course of business.

            Section 3.15 Limitation On Asset Sales.

            (a) The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, consummate an Asset Sale unless:

            (i) the Company or the applicable Restricted Subsidiary, as the case
      may be, receives consideration at the time of the Asset Sale at least
      equal to the Fair Market Value of the assets sold or otherwise disposed
      of, and

            (ii) at least 75% of the consideration received for the assets
      disposed of by the Company or the Restricted Subsidiary, as the case may
      be, in the Asset Sale shall be in the form of:

            (1) cash or Cash Equivalents, or

            (2) (A) tangible or intangible assets to be used by the Company or
      any Restricted Subsidiary in the Telecommunications Business, or

            (B) Capital Stock of a Person engaged, except to a de minimis
      extent, solely in a Telecommunications Business that will become, upon
      purchase, a Restricted Subsidiary (collectively, "Replacement Assets"),

            (b) The Company or such Restricted Subsidiary, as the case may be,
may apply the Net Cash Proceeds of any such Asset Sale within 360 days of
receipt thereof to:

            (i) permanently repay or repurchase outstanding (without Refinancing
      and including a permanent reduction in commitments in the case of a
      revolving credit facility) (x) Indebtedness of the Company (other than
      Subordinated Indebtedness or Disqualified Stock) that is secured
      Indebtedness or which has a final maturity date prior to the final
      maturity date of the Notes or (y) Indebtedness (other than Disqualified
      Stock) of any Restricted Subsidiary, or

            (ii) purchase Replacement Assets from a Person other than the
      Company and its Subsidiaries.

            The balance of the Net Cash Proceeds that are not applied or
invested as described in the immediately preceding clauses (i) and (ii), shall
constitute "Excess Proceeds."

            (c) When the aggregate amount of Excess Proceeds equals or exceeds
$25 million, taking into account income earned on such Excess Proceeds, the
Company will be required to make a pro rata offer (an "Asset Sale Offer") to all
holders of Notes and of pari passu Indebtedness with comparable provisions
requiring such Indebtedness to be purchased with the proceeds of such Asset Sale
to purchase the maximum principal amount (or accreted value in the case of
Indebtedness issued with original issue discount) (the "Asset Sale Offer
Amount") of


                                       51
<PAGE>

Notes and such pari passu Indebtedness that may be purchased with the Excess
Proceeds, at a purchase price in cash in an amount equal to 100% of the
principal amount thereof (or the accreted value thereof in the case of
Indebtedness issued with original issue discount) plus accrued and unpaid
interest or accretion thereon to the date of purchase, subject to the right of
holders on the relevant record date to receive interest due on the relevant
interest payment date, in accordance with the procedures set forth in the
Indenture and the agreements governing such pari passu Indebtedness. To the
extent that any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use such Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount (or accreted
values) of Notes and pari passu Indebtedness tendered into such Asset Sale Offer
surrendered by holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes and pari passu Indebtedness to be purchased on a
pro rata basis in proportion to the respective principal amounts (or accreted
values) of the Notes and such other Indebtedness. Upon completion of such Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero for purposes of
the first sentence of this paragraph.

            (d) Pending application in accordance with this Section 3.15, Net
Cash Proceeds may be applied to temporarily reduce revolving credit borrowings
which can be reborrowed or invested in Cash Equivalents. An Asset Sale Offer
Notice will be mailed first class, postage prepaid, to the record Holders as
shown on the register of Holders within 30 days following such 360th day, with a
copy to the Trustee offering to purchase the Notes as described above. Each
notice of an Asset Sale Offer shall state, among other things, the purchase
date, which must be no earlier than 30 days nor later than 60 days from the date
the notice is mailed, other than as may be required by law (the "Asset Sale
Offer Payment Date"). Upon receiving an Asset Sale Offer Notice, Holders may
elect to tender their Notes in whole or in part in integral multiples of Euro
1,000 in exchange for cash.

            (e) On the Asset Sale Offer Payment Date, the Company will, to the
extent lawful:

            (1) accept for payment all Notes or portions thereof properly
      tendered pursuant to the Asset Sale Offer (or, if the Trustee is acting as
      agent for the Company, direct the Trustee to so accept);

            (2) deposit with the Paying Agent funds in an amount equal to the
      Asset Sale Offer Amount in respect of all Notes or portions thereof so
      tendered; and

            (3) deliver or cause to be delivered to the Trustee (including by
      designating the Trustee as its agent for acceptance of Notes) the Notes so
      accepted together with an Officers' Certificate stating the aggregate
      principal amount of Notes or portions thereof being purchased by the
      Company.

            (f) The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other applicable securities laws in connection
with the purchase of Notes pursuant to an Asset Sale Offer. To the extent that
the provisions of any applicable securities laws or regulations conflict with
this Section 3.15, the Company shall comply with these laws


                                       52
<PAGE>

and regulations and shall not be deemed to have breached its obligations under
this Section 3.15 by doing so.

            (g) In the event of the transfer of substantially all (but not all)
of the property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 4.1 the surviving
entity shall be deemed to have sold the properties and assets of the Company and
its Restricted Subsidiaries not so transferred for purposes of this Section
3.15, and shall comply with the provisions of this Section 3.15 with respect to
the deemed sale as if it were an Asset Sale. In addition, the Fair Market Value
of properties and assets of the Company or its Restricted Subsidiaries so deemed
to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section
3.15.

            (h) If at any time any non-cash consideration received by the
Company or any Restricted Subsidiary, as the case may be, in connection with any
Asset Sale is converted into or sold or otherwise disposed of for cash (other
than interest received with respect to any non-cash consideration), the
conversion or disposition shall be deemed to constitute an Asset Sale hereunder
and the Net Cash Proceeds thereof shall be applied in accordance with this
Section 3.15 within 360 days of conversion or disposition.

            Section 3.16.  Limitation On Transactions With Affiliates.

            (1) The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless:

            (a) such Affiliate Transaction is on terms that are not materially
less favorable to the Company or the relevant Restricted Subsidiary than those
that would have been obtained in a comparable transaction on an arm's length
basis by the Company or such Restricted Subsidiary with a Person that is not an
Affiliate, and

            (b)  with respect to any Affiliate Transaction or series of related
Affiliate Transactions:

            (x) involving aggregate consideration in excess of $10 million, the
      Company delivers to the Trustee a resolution of the Board of Directors set
      forth in an Officers' Certificate that such Affiliate Transaction is
      approved by a majority of the disinterested members of the Board of
      Directors and certifying that such Affiliate Transaction complies with
      clause (a) above and is in the best interests of the Company or such
      Restricted Subsidiary, or

            (y) if involving aggregate consideration in excess of $25 million, a
      favorable written opinion as to the fairness to the Company of such
      Affiliate Transaction from a financial point of view is also obtained by
      the Company from an independent accounting, appraisal or investment
      banking firm of national standing and delivered to the Trustee.

            (2)  Clause (1) will not apply to the following:


                                       53
<PAGE>

            (a) the entering into, maintaining or performance of any employment
contract, collective bargaining agreement, benefit plan, program or arrangement,
related trust agreement or any other similar arrangement for or with any
employee, officer or director of the Company or any Restricted Subsidiary
heretofore or hereafter entered into in the ordinary course of business,
including vacation, health, insurance, deferred compensation, retirement,
savings or other similar plans;

            (b) the payment of compensation, performance of indemnification or
contribution obligations, or an issuance, grant or award of stock, options, or
other equity-related interests or other securities, to employees, officers or
directors of the Company or any Restricted Subsidiary in the ordinary course of
business;

            (c)  transactions between or among the Company and/or its Restricted
Subsidiaries;

            (d)  payment of reasonable fees to directors of the Company;

            (e)  any sale or other issuance of Capital Stock (other than
Disqualified Stock) of the Company;

            (f) Affiliate Transactions in effect or approved by the Board of
Directors on the Issue Date, including any amendments thereto; provided that the
terms of such amendments are not materially less favorable to the Company than
the terms of such agreement prior to such amendment;

            (g)  Restricted Payments that are permitted by Section 3.11; and

            (h) (x) the Primary Supplier Agreement dated January 18, 2000
between Bell Atlantic Global Systems Company and the Company, including any
amendments thereto, provided that the terms of such amendments are not
materially less favorable to the Company than the terms of such agreements prior
to such amendment, or

            (y) any transaction with respect to capacity and/or the provision of
      telecommunications services between the Company or any Restricted
      Subsidiary and any Affiliates, provided that such transaction complies
      with clause (1)(a) of this Section 3.16.

            Section 3.17.  Limitation On Business Activities.
            The Company will not, and will not permit any of its Restricted
Subsidiaries to, engage, to more than a de minimus extent, in any business other
than a Telecommunications Business.

            Section 3.18.  Reports To Holders.

            Whether or not the Company is subject to the reporting requirements
of Section 13 or 15(d) of the Exchange Act, so long as any Notes remain
outstanding, the Company will:


                                       54
<PAGE>

            (1) provide the Trustee and the Holders with the annual reports and

15(d) of the Exchange Act subject to such Sections within 15 days after the

satisfying the requirements therefor established by the Commission; and

            (2) file with the Commission, to the extent permitted, the
information, documents and reports referred to in clause (1) within the periods
specified under such Sections; provided that the quarterly information specified
in clause (1) shall be filed within 45 days after the end of the relevant fiscal
quarter or such shorter time established by the Commission.

            At any time when the Company is not subject to or is not current in
its reporting obligations under clause (2) of the preceding paragraph, the
Company will make available, upon request, to any holder and any prospective
purchaser of Notes the information required pursuant to Rule 144A(d)(4) under
the Securities Act.

                                   ARTICLE IV

            Section 4.1. Merger, Consolidation and Sale of Assets. The Company
will not, directly or indirectly, consolidate or merge with or into (whether or
not the Company is the surviving corporation), or sell, assign, transfer, convey
or otherwise dispose of all or substantially all of its properties or assets, in
one or more related transactions, to another Person unless:

            (1) the Company is the surviving corporation or the Person formed by

which such sale, assignment, transfer, conveyance or other disposition shall
have been made is a corporation organized or existing under the laws of Bermuda

obligations of the Company under the Registration Agreement, the Notes and this
Indenture pursuant to supplemental indenture in a form reasonably satisfactory
to the Trustee;

            (3) no Default or Event of Default shall exist or shall occur
immediately after giving effect on a pro forma basis to such transaction;

            (4) except in the case of a merger of the Company with or into a
Wholly Owned Restricted Subsidiary of the Company, the Company or the Person
formed by or surviving any such consolidation or merger (if other than the
Company), or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made will immediately after such transaction and
after giving pro forma effect thereto and any related financing transactions as

to incur at least $1.00 of additional Indebtedness pursuant to paragraph (1) of
Section 3.10;

            (5) if, as a result of any such transaction, property or assets of
the Company or any Restricted Subsidiary would become subject to a Lien (other
than a Permitted Lien), the Company or the successor entity to the Company shall
have secured the Notes as required by Section 3.10; and

            (6) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and such supplemental indenture (if any) comply with this
Indenture.

                                    ARTICLE V

                          OPTIONAL REDEMPTION OF NOTES

            Section 5.1. Optional Redemption. The Company may redeem the Notes,
as a whole or from time to time in part, at any time on or after March 30, 2005,
subject to the conditions and at the redemption prices specified in the form of
Notes in Exhibit A. In addition, at any time prior to March 30, 2003, the
Company may redeem a portion of the Notes at the redemption prices specified in
the form of Notes in Exhibit A with the proceeds of Public Equity Offerings.

            Section 5.2.  Election to Redeem.  The Company shall evidence its
election to redeem any Notes pursuant to Section 5.1 by a Board Resolution.

            Section 5.3.  Notice of Redemption.

            (a) The Company shall give or cause the Trustee to give notice of
redemption, in the manner provided for in Section 11.2, not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Notes to be
redeemed at its registered address. If the Company itself gives the notice, it
shall also deliver a copy to the Trustee.

            (b) If either (i) the Company is not redeeming all Outstanding
Notes, or (ii) the Company elects to have the Trustee give notice of redemption,
then the Company shall deliver to the Trustee, at least 45 days prior to the
Redemption Date (unless the Trustee is satisfied with a shorter period), an
Officer's Certificate requesting that the Trustee select the Notes to be
redeemed and/or give notice of redemption and setting forth the information
required by paragraph (c) of this Section 5.3 (with the exception of the
identification of the particular Notes, or portions of the particular Notes, to
be redeemed in the case of a partial redemption). If the Company elects to have
the Trustee give notice of redemption, the Trustee shall give the notice in the
name of the Company and at the Company's expense.

            (c)  All notices of redemption shall state:

                  (1)  the Redemption Date,


                                       56
<PAGE>

                  (2) the redemption price and the amount of any accrued
      interest payable as provided in Section 5.6,

                  (3) whether or not the Company is redeeming all Outstanding
      Notes,

                  (4) if the Company is not redeeming all Outstanding Notes, the
      aggregate principal amount of Notes that the Company is redeeming and the
      aggregate principal amount of Notes that will be Outstanding after the
      partial redemption, as well as the identification of the particular Notes,
      or portions of the particular Notes, that the Company is redeeming,

                  (5) if the Company is redeeming only part of a Note, the
      notice that relates to that Note shall state that on and after the
      Redemption Date, upon surrender of that Note, the Holder will receive,
      without charge, a new Note or Notes of authorized denominations for the
      principal amount of the Note remaining unredeemed,

                  (6) that on the Redemption Date the redemption price and any
      accrued interest payable to the Redemption Date as provided in Section 5.6
      will become due and payable in respect of each Note, or the portion of
      each Note, to be redeemed, and, unless the Company defaults in making the
      redemption payment, that interest on each Note, or the portion of each
      Note, to be redeemed, will cease to accrue on and after the Redemption
      Date,

                  (7) the place or places where a Holder must surrender the
      Holder's Notes for payment of the redemption price, and

                  (8) the ISIN number, if any, listed in the notice or printed
      on the Notes, and that no representation is made as to the accuracy or
      correctness of such ISIN number.

            Section 5.4. Selection of Notes to Be Redeemed in Part. (a) If the
Company is not redeeming all Outstanding Notes, the Trustee shall select the
Notes to be redeemed in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not then listed on a national securities exchange, on a pro rata
basis, by lot or in another fair and reasonable manner chosen at the discretion
of the Trustee; provided, however, that if a partial redemption is made with the
proceeds of a Public Equity Offering, selection of the Notes, or portions of the
Notes, for redemption shall be made by the Trustee only on a pro rata basis as
is practicable (subject to the procedures of Euroclear or Clearstream,
Luxembourg, as the case may be), unless that method is prohibited. The Trustee
shall make the selection from the Outstanding Notes not previously called for
redemption. The Trustee shall promptly notify the Company in writing of the
Notes selected for redemption and, in the case of any Notes selected for partial
redemption, the principal amount of the Notes to be redeemed. In the event of a
partial redemption by lot, the Trustee shall select the particular Notes to be
redeemed not less than 30 nor more than 60 days prior to the relevant Redemption
Date from the Outstanding Notes not previously called for redemption. The
Company may redeem Notes in denominations of Euro 1,000 only in whole. The
Trustee may select for redemption portions (equal to Euro 1,000 or any integral
multiple of Euro 1,000) of the principal of Notes that have denominations larger
than Euro 1,000.


                                       57
<PAGE>

            (b) For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Notes shall relate, in the
case of any Note redeemed or to be redeemed only in part, to the portion of the
principal amount of that Note which has been or is to be redeemed.

            Section 5.5. Deposit of Redemption Price. On or prior to 10 a.m. on
the relevant Redemption Date, the Company shall deposit with the Trustee or with
a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 2.4) an amount of money in immediately
available funds sufficient to pay the redemption price of, and accrued interest
on, all the Notes that the Company is redeeming on that date.

            Section 5.6. Notes Payable on Redemption Date. If the Company, or
the Trustee on behalf of the Company, gives notice of redemption in accordance
with this Article V, the Notes, or the portions of Notes, called for redemption,
shall, on the Redemption Date, become due and payable at the redemption price
specified in the notice (together with accrued and unpaid interest, if any, to
the Redemption Date), and from and after the Redemption Date (unless the Company
shall default in the payment of the redemption price and accrued interest) the
Notes or the portions of Notes shall cease to bear interest. Upon surrender of
any Note for redemption in accordance with the notice, the Company shall pay the
Notes at the redemption price, together with accrued and unpaid interest, if
any, to the Redemption Date (subject to the rights of Holders of record on the
relevant record date to receive interest due on the relevant Interest Payment
Date). If the Company shall fail to pay any Note called for redemption upon its
surrender for redemption, the principal shall, until paid, bear interest from
the Redemption Date at the rate borne by the Notes.

            Section 5.7. Unredeemed Portions of Partially Redeemed Note. Upon
surrender of a Note that is to be redeemed in part, the Company shall execute,
and the Trustee shall authenticate and make available for delivery to the Holder
of the Note at the expense of the Company, a new Note or Notes, of any
authorized denomination as requested by the Holder, in an aggregate principal
amount equal to, and in exchange for, the unredeemed portion of the principal of
the Note surrendered, provided that each new Note will be in a principal amount
of Euro 1,000 or integral multiple of Euro 1,000.

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

      amount of the Notes;

            (5)  default by the Company or any Restricted Subsidiary under any
      Indebtedness which:

      period; or

            (b) results in the acceleration of such Indebtedness prior to its

      of the affairs of the Company or any Restricted Subsidiary of the Company,
      and in each case, the continuance of any such decree or order for relief
      or any such other decree or order unstayed and in effect for a period of
      60 consecutive calendar days; or

            (8) (i) the commencement by the Company or any Restricted Subsidiary
      of the Company of a voluntary case or proceeding under any Bankruptcy Law

      generally as they become due, or (vii) the approval by stockholders of the
      Company or any Restricted Subsidiary of the Company of any plan or
      proposal for the liquidation or dissolution of the Company or any
      Restricted Subsidiary of the Company, or (viii) the taking of corporate
      action by the Company or any Restricted Subsidiary of the Company in
      furtherance of any such action.

The foregoing will constitute Events of Default whatever the reason for any such
Event of Default and whether it is voluntary or involuntary or is effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

            (b) The Company shall deliver to the Trustee upon becoming aware of
any Default or Event of Default written notice in the form of an Officers'
Certificate of any Default or Event of Default, their status and what action the
Company is taking or proposes to take in respect thereof.

            Section 6.2.  Acceleration.

            (a) If an Event of Default (other than an Event of Default specified
in clauses (7) and (8) above with respect to the Company) shall occur and be
continuing, the Trustee or the Holders of at least 25% in principal amount of
outstanding Notes may declare the unpaid principal of and accrued and unpaid
interest on all the Notes to be immediately due and payable by notice in writing
to the Company and the Trustee specifying the Event of Default and that it is a
"notice of acceleration." If an Event of Default specified in clauses (7) and
(8) above occurs with respect to the Company, then the unpaid principal of and
accrued and unpaid interest on all the Notes will become immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

            (b) At any time after a declaration of acceleration with respect to
the Notes as described in the preceding paragraph, the Holders of a majority in
principal amount of such Notes may rescind and cancel such declaration and its
consequences:

            (1) if the rescission would not conflict with any judgment or
      decree;


                                       60
<PAGE>

            (2) if all existing Events of Default have been cured or waived,
      except nonpayment of principal or interest that has become due solely
      because of the acceleration;

            (3) to the extent the payment of such interest is lawful, interest
      on overdue installments of interest and overdue principal, which has
      become due otherwise than by such declaration of acceleration, has been
      paid; and

            (4) if the Company has paid the Trustee its reasonable compensation
      and reimbursed the Trustee for its reasonable expenses, disbursements and
      advances.

No recission shall affect any subsequent Default or impair any rights relating
thereto.

            Section 6.3. Other Remedies.

            (a) If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal of and interest
on the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

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

            Section 6.4. Waiver of Past Defaults. The Holders of a majority in
principal amount of the Notes may waive any existing Default or Event of
Default, and its consequences, except a default in the payment of the principal
of, premium, if any, or interest on such Notes.

            Section 6.5. Control by Majority. The Holders of a majority in
principal amount of the Outstanding Notes may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. Subject to Sections 7.1
and 7.2, however, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction.

            Section 6.6. Limitation on Suits. (a) Subject to the provisions of
this Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under this Indenture at the
request, order or direction of any of the Holders of the Notes unless such
Holders have offered to the Trustee reasonable security or indemnity. Subject to
all provisions of this Indenture and applicable law, the Holders of a majority
in aggregate principal amount of the then outstanding Notes 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.

            (b) No Holder of any Notes will have any right to institute any
proceeding with respect to this Indenture or for any remedy thereunder, unless:


                                       61
<PAGE>

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

            (2) Holders of at least 25% in principal amount of the then
      outstanding Dollar Notes or Euro Notes, as the case may be, make a written
      request to pursue the remedy;

            (3)  such Holders of the Dollar Notes or Euro Notes, as the case may
      be, provide to the Trustee satisfactory indemnity;

            (4)  the Trustee does not comply within 60 days; and

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

            Otherwise, no Holder of any Notes will have any right to institute
any proceeding with respect to this Indenture or for any remedy hereunder,
except:

            (1) a Holder of Notes may institute suit for enforcement of payment
of the principal of and premium, if any, or interest on such Note held by it on
or after the respective due dates expressed in such Note, or

            (2) for the institution of any proceeding with respect to this
Indenture or any remedy hereunder, including, without limitation, acceleration,
by the Holders of a majority in principal amount of the outstanding Notes;
provided, that upon institution of any proceeding or exercise of any remedy,
such Holder or Holders provide the Trustee with prompt notice thereof.

            Section 6.7. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture (including, without limitation, Section
6.6), the right of any Holder to receive payment of principal of or interest on
the Notes held by such Holder, on or after the respective due dates, Redemption
Dates or repurchase date expressed in this Indenture or the Notes, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

            Section 6.8. Collection Suit by Trustee. If an Event of Default
specified in Section 6.1 (1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with applicable
interest on any overdue principal and, to the extent lawful, interest on overdue
interest) and the amounts provided for in Section 7.7.

            Section 6.9.  Trustee May File Proofs of Claim, etc.

            (a)  The Trustee may (irrespective of whether the principal of the
Notes is then due):

            (i) file such proofs of claim and other papers or documents as may
      be necessary or advisable in order to have the claims of the Trustee and
      the Holders under this Indenture and the Notes allowed in any bankruptcy,
      insolvency, liquidation or other


                                       62
<PAGE>

      judicial proceedings relative to the Company or any Subsidiary of the
      Company or its or their respective creditors or properties; and

            (ii) collect and receive any monies or other property payable or
      deliverable in respect of any such claims and distribute them in
      accordance with this Indenture.

Any receiver, trustee, liquidator, sequestrator (or other similar official) in
any such proceeding is hereby authorized by each Holder to make such payments to
the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, taxes, disbursements and advances
of the Trustee, its agent and counsel, and any other amounts due to the Trustee
pursuant to Section 7.7.

            (b) Nothing in 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
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceeding.

            Section 6.10. Priorities. If the Trustee collects any money or
property pursuant to this Article VI, it shall pay out the money or property in
the following order:

            FIRST: to the Trustee for amounts due under Section 7.7;

            SECOND: if the Holders proceed against the Company directly without
      the Trustee in accordance with this Indenture, to Holders for their
      collection costs;

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

            FOURTH: to the Company or to such party as a court of competent
      jurisdiction shall direct.

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

            Section 6.11. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by the Company, a suit by a Holder pursuant to Section 6.7 or a
suit by Holders of more than 10% in principal amount of Outstanding Notes.

                                   ARTICLE VII

                                     TRUSTEE

            Section 7.1. Duties of Trustee.

            (a) If a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise 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.

            (b) Except during the continuance of a Default or 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 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.
      However, in the case of any such certificates or opinions which by any
      provisions hereof are specifically required to be furnished to the
      Trustee, the Trustee shall examine such certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture (but need not confirm or investigate the accuracy of
      mathematical calculations or other facts stated therein).

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

            (1) this paragraph (c) does not limit the effect of paragraph (b) of
      this Section 7.1;

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

            (3) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.2, 6.4 or 6.5.

            (d) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

            (e) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

            (f) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder


                                       64
<PAGE>

or in the exercise of any of its rights or powers, if it shall have reasonable
grounds to believe that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.

            (g) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Article VII and to the provisions of the TIA.

            (h) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

            (i) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

            Section 7.2. Rights of Trustee. Subject to Section 7.1:

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

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

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

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute
willful misconduct or negligence.

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

            (f) If the Trustee shall determine, it shall be entitled to examine
the books, records and premises of the Company, personally or by agent or
attorney.

            (g) The Trustee shall not be deemed to have notice of any Default or
Event of Default unless an 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 Notes and this Indenture.


                                       65
<PAGE>

            (h) The rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder.

            (i) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

            Section 7.3. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee. Any Paying Agent, Registrar or
co-Registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

            Section 7.4. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Company's use
of the proceeds from the Notes, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Trustee's
certificate of authentication.

            Section 7.5.  Notice of Defaults.

            If a Default or Event of Default occurs and is continuing and if a
Trust Officer has actual knowledge thereof, the Trustee shall mail to each
Holder notice of the Default or Event of Default within 90 days after the
occurrence thereof. Except in the case of a Default or Event of Default in
payment of principal of or interest on any Note (including payments pursuant to
the optional redemption or required repurchase provisions of such Note, if any),
the Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of the Holders.

            Section 7.6. Reports by Trustee to Holders. The Trustee shall comply
with TIA ss. 313. The Company agrees to notify promptly the Trustee whenever the
Notes become listed on any stock exchange and of any delisting thereof.

            Section 7.7.  Compensation and Indemnity.

            (a) The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the
Company and the Trustee shall from time to time agree in writing. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, costs of preparing and reviewing reports, certificates and other


                                       66
<PAGE>

documents, costs of preparation and mailing of notices to Holders and reasonable
costs of counsel retained by the Trustee in connection with the delivery of an
Opinion of Counsel or otherwise, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts.

            (b) The Company shall indemnify the Trustee against any and all
loss, liability or expense (including reasonable attorneys' fees and expenses)
incurred by it without gross negligence, willful misconduct or bad faith on its
part in connection with the acceptance and administration of this trust and the
performance of its duties hereunder, including the costs and expenses of
enforcing this Indenture (including this Section 7.7) and of defending itself
against any claims (whether asserted by any Holder, the Company or otherwise).
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee may have separate counsel and the Company shall pay the fees and
expenses of such counsel provided that the Company shall not be required to pay
such fees and expenses if it assumes the Trustee's defense, and, in the
reasonable judgment of outside counsel to the Trustee, there is no conflict of
interest between the Company and the Trustee in connection with such defense.
The Company need not reimburse any expense or indemnify against any loss,
liability or expense incurred by the Trustee through the Trustee's own willful
misconduct, gross negligence or bad faith.

            (c) To secure the Company's payment obligations in this Section 7.7,
the Trustee shall have a lien prior to the Notes on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Notes. The Trustee's right to receive
payment of any amounts due under this Section 7.7 shall not be subordinate to
any other liability or Indebtedness of the Company.

            (d) The Company's payment obligations pursuant to this Section 7.7
shall survive the discharge of this Indenture and the resignation or removal of
the Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.1(7) or (8) , the expenses are intended to constitute
expenses of administration under any Bankruptcy Law; provided, however, that
this shall not affect the Trustee's rights as set forth in this Section 7.7 or
Section 6.10.

            Section 7.8. Replacement of Trustee.

            (a) The Trustee may resign at any time by so notifying the Company.
The Holders of a majority in principal amount of the Outstanding Notes may
remove the Trustee by so notifying the Trustee and may appoint a successor
Trustee reasonably acceptable to the Company. The Company shall remove the
Trustee if:

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee otherwise becomes incapable of acting.


                                       67
<PAGE>

            (b) If the Trustee resigns or is removed by the Company or by the
Holders of a majority in principal amount of the Outstanding Notes and such
Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy
exists in the office of the Trustee for any reason (the Trustee in such event
being referred to herein as the retiring Trustee), the Company shall promptly
appoint a successor Trustee.

            (c) A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject to the lien provided for
in Section 7.7.

            (d) If a successor Trustee does not take office within 30 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders
of 10% in principal amount of the Outstanding Notes may petition, at the
Company's expense, any court of competent jurisdiction for the appointment of a
successor Trustee.

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

            (f) Notwithstanding the replacement of the Trustee pursuant to this
Section 7.8, the Company's obligations under Section 7.7 shall continue for the
benefit of the retiring Trustee.

            Section 7.9. Successor Trustee by Merger.

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

            (b) In case at the time such successor or successors to the Trustee
shall succeed to the trusts created by this Indenture, any of the Notes shall
have been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not
have been authenticated, any successor to the Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Notes or in this Indenture provided that
the certificate of the Trustee shall have.

            Section 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have a
combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities or


                                       68
<PAGE>

certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

            Section 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

            Section 7.12. Appointment of Co-Trustee. (a) Notwithstanding any
other provisions in this Indenture, at any time, solely for the purpose of
meeting the legal requirements of any jurisdiction, the Trustee shall have the
power and may execute and deliver all instruments necessary to appoint one or
more Persons to act as separate trustee or trustees or as co-trustee or
co-trustees, and to vest in such Person or Persons, in such capacity and subject
to the other provisions of this Indenture, such powers, duties, obligations and
rights as the Trustee may consider necessary or desirable. No co-trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under this Indenture and no notice to holders of Notes of the
appointment of a separate trustee or co-trustee shall be required under this
Indenture.

            (b) Every separate trustee or co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

            (i) all rights, powers, duties and obligations conferred or imposed
      upon the Trustee shall be conferred or imposed upon and exercised or
      performed by the Trustee and such separate trustee or co-trustee jointly
      (it being understood that such separate trustee or co-trustee us not
      authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations shall be exercised and
      performed singly by such co-trustee, but solely at the direction of the
      Trustee;

            (ii) no trustee hereunder shall be personally liable by reason of
      any act or omission of any other trustee hereunder; and

            (iii) the Trustee may at any time accept the resignation of or
      remove any separate trustee or co-trustee.

            (c) Any notice, request or other writing given to the Trustee shall
      be deemed to have been given to each of the then separate trustees or
      co-trustees, as effectively as if given to each of them. Every instrument
      appointing any separate trustee or co-trustee shall refer to this
      Indenture and the conditions of this Article VII. Each separate trustee or
      co-trustee, upon its acceptance of the trusts conferred, shall be vested
      with the estates or property specified in its instrument of appointment,
      jointly with the Trustee, subject to all the provisions of this Indenture,
      specifically including every provision of this Indenture relating to the
      conduct of, affecting the liability of, or affording protection or rights
      (including the rights to compensation, reimbursement and indemnification
      hereunder) to, the Trustee. Every such instrument shall be filed with the
      Trustee.


                                       69
<PAGE>

            (d) Any separate trustee or co-trustee may at any time constitute
the Trustee or its agent or attorney-in-fact with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
this Indenture on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                                  ARTICLE VIII

                       DEFEASANCE; DISCHARGE OF INDENTURE

            Section 8.1.  Legal Defeasance and Covenant Defeasance.

            (a) The Company may, at its option, at any time, elect to have
either paragraph (b) or (c) of this Section 8.1 be applied to all Outstanding
Notes upon compliance with the conditions set forth in Section 8.2.

            (b) Upon the Company's exercise under paragraph (a) of this Section
8.1 of the option applicable to this paragraph (b), the Company shall, subject
to the satisfaction of the conditions set forth in Section 8.2, be deemed to
have paid and been discharged from its obligations with respect to all
Outstanding Notes on the date all of the conditions set forth in Section 8.2
(including Section 8.2(4)(b)) are satisfied (hereinafter, "Legal Defeasance").
For this purpose, Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire Indebtedness represented by the Outstanding
Notes, which shall thereafter be deemed to be Outstanding only for the purposes
of Section 8.3 and the other Sections of this Indenture referred to in clause
(i) or (ii) of this paragraph (b), and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions, which shall
survive until otherwise terminated or discharged hereunder:

            (i) the rights of Holders of Outstanding Notes to receive solely
      from the trust fund described in Section 8.3, and as more fully set forth
      in Section 8.3, payments in respect of the principal of and interest on
      such Notes when such payments are due,

            (ii) the Company's obligations with respect to such Notes under
      Article II and Section 3.2,

            (iii) the rights, powers, trusts, duties and immunities of the
      Trustee hereunder and the Company's obligations in connection therewith,
      and

            (iv) this Article VIII.

Subject to compliance with this Article VIII, the Company may exercise its
option under this paragraph (b) notwithstanding the prior exercise of its option
under paragraph (c) of this Section 8.1.

            (c) Upon the Company's exercise under paragraph (a) of this Section
8.1 of the option applicable to this paragraph (c), the Company shall, subject
to the satisfaction of the


                                       70
<PAGE>

applicable conditions set forth in Section 8.2, be released from its obligations
under the covenants contained in Sections 3.4, 3.5, 3.8 to 3.18 and 4.1 with
respect to the Outstanding Notes on and after the date the conditions set forth
below are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not Outstanding for the purposes of any direction, waiver,
consent or declaration or act of Holders (and the consequences of any thereof)
in connection with such covenants, but shall continue to be Outstanding for all
other purposes hereunder (it being understood that such Notes shall not be
deemed Outstanding for accounting purposes). For this purpose, such Covenant
Defeasance means that, with respect to the Outstanding Notes, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event or Default under Section 6.1(3) to (6), but, except as specified
above, the remainder of this Indenture and such Notes shall be unaffected
thereby.

            Section 8.2. Conditions to Defeasance. The Company may exercise its
Legal Defeasance option or its Covenant Defeasance option only if:

            (1) the Company irrevocably deposits with the Trustee, in trust for
      the benefit of the Holders, Euros, European Union Obligations or a
      combination thereof in such amounts as will be sufficient without
      reinvestment, in the opinion of a nationally recognized firm of
      independent public accountants, to pay the principal of and interest on
      the Notes on the stated date for payment thereof or on the applicable
      redemption date, as the case may be, and the Trustee has a perfected first
      priority security interest under applicable law in such Euros and European
      Union Obligations;

            (2) in the case of Legal Defeasance, the Company shall have
      delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee to the effect that: (A) the Company
      has received from, or there has been published by, the Internal Revenue
      Service a ruling or (B) since the Issue Date, there has been a change in
      the applicable federal income tax law, in either case to the effect that,
      and based thereon such Opinion of Counsel shall state that, the Holders
      will not recognize income, gain or loss for federal income tax purposes as
      a result of such Legal Defeasance and will be subject to federal income
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if such Legal Defeasance had not occurred;

            (3) in the case of Covenant Defeasance, the Company shall have
      delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee to the effect that the Holders will
      not recognize income, gain or loss for federal income tax purposes as a
      result of such Covenant Defeasance and will be subject to federal income
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if such Covenant Defeasance had not occurred;

            (4) the Trustee shall have received, on the date of the deposit
      pursuant to paragraph (1) above and on the 91st day after such date, an
      Officers' Certificate stating that (a) no Default or Event of Default
      shall have occurred and be continuing on the date


                                       71
<PAGE>

      of the deposit pursuant to paragraph (1) above (except any Default or
      Event of Default resulting from the failure to comply with Section 3.10
      hereof as a result of the borrowing of the funds required to effect such
      deposit) and, (b) insofar as Events of Default from bankruptcy or
      insolvency events are concerned, no Default or Event of Default shall have
      occurred at any time in the period ending on the 91st day after the date
      of deposit and, in the case of Legal Defeasance, no such Default or Event
      of Default shall have occurred and be continuing on such 91st day;

            (5) the Trustee shall have received an Officers' Certificate stating
      that such Legal Defeasance or Covenant Defeasance shall not result in a
      breach or violation of, or constitute a default under this Indenture or
      any other material agreement or instrument to which the Company or any of
      its Restricted Subsidiaries is a party or by which the Company or any of
      its Subsidiaries is bound;

            (6) the Company shall have delivered to the Trustee an Officers'
      Certificate stating that the deposit was not made by the Company with the
      intent of preferring the Holders over any other creditors of the Company
      or any Subsidiary of the Company or with the intent of defeating,
      hindering, delaying or defrauding any other creditors of the Company or
      others;

            (7) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with;

            (8) the Company shall have delivered to the Trustee an Opinion of
      Counsel to the effect that after the 91st day following the deposit, the
      trust funds will not be subject to the effect of any applicable
      bankruptcy, insolvency, reorganization or similar laws affecting
      creditors' rights generally; and

            (9) the Company shall have delivered to the Trustee an Opinion of
      Counsel (subject to customary assumptions and exclusions) to the effect
      that the trust resulting from the deposit does not constitute, or is
      qualified as, a regulated investment company under the Investment Company
      Act of 1940.

            Section 8.3. Application of Trust Money. The Trustee shall hold in
trust Euros or European Union Obligations deposited with it pursuant to this

            (a) The Trustee and the Paying Agent shall promptly turn over to the
Company upon request any excess money or securities held by them upon payment of
all the obligations under this Indenture.

            (b) Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of


                                       72
<PAGE>

principal of or interest on the Notes that remains unclaimed for two years, and,
thereafter, Holders entitled to the money must look to the Company for payment
as general creditors.

            Section 8.5. Indemnity for European Union Obligations The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited European Union Obligations or the
principal and interest received on such European Union Obligations.

            Section 8.6. Reinstatement. If the Trustee or Paying Agent is unable
to apply any Euros or European Union Obligations in accordance with this Article
VIII 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 Company under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to this Article VIII until such time as the Trustee or Paying
Agent is permitted to apply all such Euros or European Union Obligations in
accordance with this Article VIII; provided, however, that, if the Company has
made any payment of interest on or principal of any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the Euros or European
Union Obligations held by the Trustee or Paying Agent.

            Section 8.7. Satisfaction and Discharge. The Indenture will be
discharged and will cease to be of further effect (except as to surviving rights
or registration of transfer or exchange of the Notes, as expressly provided for
in the Indenture) as to all Outstanding Notes when:

            (a)  either:

            (1) all the Notes theretofor executed, authenticated and delivered
      (except lost, stolen or destroyed Notes which have been replaced or paid
      and Notes for whose payment money has theretofor been deposited in trust
      or segregated and held in trust by the Company and thereafter repaid to
      the Company or discharged from such trust) have been delivered to the
      Trustee for cancellation; or

            (2) all Notes not theretofor delivered to the Trustee for
      cancellation have become due and payable, and the Company has irrevocably
      deposited or caused to be deposited with the Trustee Euros or European
      Union Obligations sufficient to pay and discharge the entire Indebtedness
      on the Notes not theretofor delivered to the Trustee for cancellation, for
      principal of and interest on the Notes to the date of deposit, together
      with irrevocable instructions from the Company directing the Trustee to
      apply such funds to the payment;

            (b) the Company has paid all other sums payable under this Indenture
and the Notes by the Company; and

            (c) the Company has delivered to the Trustee an Officers'
Certificate stating that all conditions precedent under this Indenture relating

                                   ARTICLE IX

                                   AMENDMENTS

            Section 9.1.  Without Consent of Holders.

            (a) The Company and the Trustee may amend this Indenture or the
Notes without notice to or consent of any Holder:

            (1)  to cure any ambiguity, omission, defect or inconsistency;

            (2) to comply with Article IV in respect of the assumption by a
      Surviving Entity of the obligations of the Company under the Notes and
      this Indenture;

            (3) to provide for uncertificated Notes in addition to or in place
      of certificated Notes; provided, however, that the uncertificated Notes
      are issued in registered form for purposes of Section 163(f) of the Code;

            (4) to add guarantees with respect to the Notes or to secure the
      Notes;

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

            (6) to comply with any requirements of the SEC in connection with
      qualifying this Indenture under the TIA;

            (7) to make any change that does not, in the opinion of the Trustee,
      adversely affect the rights of any Holder in any material respect; or

            (8) to provide for the issuance of the Exchange Notes and Private
      Exchange Notes, which will have terms substantially identical to the other
      Outstanding Notes except for the requirement of a Private Placement Legend
      and related transfer restrictions under the Securities Act and this
      Indenture and as to the applicability of additional interest payable as
      provided in Section 2.14, and which will be treated, together with any
      other Outstanding Notes, as a single issue of securities.

            (b) After an amendment under this Section 9.1 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.1.

            Section 9.2.  With Consent of Holders.

            (a) The Company and the Trustee may amend this Indenture or the
Notes without notice to any Holder but with the written consent of the Holders
of at least a majority in principal amount of the then Outstanding Notes
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes). However, without the consent
of each Holder affected, an amendment may not:


                                       74
<PAGE>

            (1) reduce the amount of Notes whose Holders must consent to an
      amendment or waiver;

            (2) reduce the rate of or change or have the effect of changing the
      time for payment of interest, including Defaulted Interest, on any Notes;

            (3) reduce the principal of or change or have the effect of changing
      the fixed maturity of any Notes, or change the date on which any Notes may
      be subject to redemption, or reduce the redemption price therefor;

            (4) make any Notes payable in money other than that stated in the
      Notes;

            (5) make any change in the provisions of this Indenture entitling
      each Holder to receive payment of principal of and interest on such Notes
      on or after the due date thereof or to bring suit to enforce such payment,
      or permitting Holders of a majority in principal amount of Outstanding
      Notes to waive Defaults or Events of Default;

            (6) amend, change or modify in any material respect any obligation
      of the Company to make and consummate a Change of Control Offer in respect
      of a Change of Control that has occurred or make and consummate an Asset
      Sale Offer with respect to any Asset Sale that has been consummated; or

            (7) amend, change or modify the seniority of the Notes or eliminate,
      release or modify any guarantee or security for the Notes except in
      accordance with the terms of the Notes or this Indenture.

            (b) It shall not be necessary for the consent of the Holders under
this Section 9.2 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent approves the substance thereof.

            (c) After an amendment under this Section 9.2 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.2.

            Section 9.3. Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Notes shall comply with the TIA as then in effect.

            Section 9.4.  Revocation and Effect of Consents and Waivers.

            (a) A consent to an amendment or a waiver by a Holder of a Note
shall bind the Holder and every subsequent Holder of that Note or portion of the
Note that evidences the same debt as the consenting Holder's Note, even if
notation of the consent or waiver is not made on the Note. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Note or portion of the Note if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Holder. An amendment or waiver
shall become effective upon receipt by the Trustee of the requisite number of
written consents under Section 9.2.


                                       75

            (b) The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 90
days after such record date.

            Section 9.5. Notation on or Exchange of Notes. If an amendment
changes the terms of a Note, the Trustee may require the Holder of the Note to
deliver it to the Trustee. The Trustee may place an appropriate notation on the
Note regarding the changed terms and return it to the Holder. Alternatively, if
the Company or the Trustee so determines, the Company in exchange for the Note
will execute and upon Company Order the Trustee will authenticate a new Note
that reflects the changed terms. Failure to make the appropriate notation or to
issue a new Note shall not affect the validity of such amendment.

            Section 9.6. Trustee to Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in
relying upon, such evidence as it deems appropriate, including, without
limitation, solely on an Opinion of Counsel stating that such amendment is
authorized or permitted by this Indenture.

the TIA shall control.

<PAGE>

Indenture or the Notes. The Company, the Trustee, the Registrar and anyone else
shall have the protection of TIA ss. 312(c).

            Section 10.4. Certificate and Opinion as to Conditions Precedent.
Upon any request or application by the Company to the Trustee to take or refrain
from taking any action under this Indenture, the Company shall furnish to the
Trustee:

            (1) an Officers' Certificate in form and substance reasonably
      satisfactory to the Trustee stating that, in the opinion of the signers,
      all conditions precedent, if any, provided for in this Indenture relating
      to the proposed action have been complied with; and

            (2) an Opinion of Counsel in form and substance reasonably
      satisfactory to the Trustee stating that, in the opinion of such counsel,
      all such conditions precedent have been complied with.

            Section 10.5. Statements Required in Certificate or Opinion. Each

provided for in this Indenture shall include:

            (1) a statement that the individual making such certificate or

            (4) a statement as to whether or not, in the opinion of such

            Section 10.7.  Currency Indemnity.

            (a) Euros are the sole currency of account and payment for all sums
payable by the Company under or in connection with the Notes or this Indenture,
including damages. Any amount received or recovered in currency other than Euro
in respect of the Notes (whether as a result of, or of the enforcement of, a
judgment or order of a court of any jurisdiction, in the winding-up or
dissolution of the Company, any Subsidiary or otherwise) by any Holder of the


                                       79
<PAGE>

Notes in respect of any sum expressed to be due to it from the Company or its
Subsidiaries shall only constitute a discharge of the Company and its
Subsidiaries under the Notes and this Indenture only 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 that Euro amount is less than the Euro
amount expressed to be due to the recipient under the Notes or this Indenture,
the Company shall indemnify and hold harmless the recipient against any loss or
cost sustained by it in making any such purchase. For the purposes of this
Section 10.7, it will be sufficient for the Holder of a Note to certify that it
would have suffered a loss had an actual purchase of Euros been made with the
amount so received in that other currency on the date of receipt or recovery
(or, if a purchase of Euros on such date had not been practicable, on the first
date on which it would have been practicable).

            (b) The indemnities of the Company contained in this Section 10.7,
to the extent permitted by law: (i) constitute a separate and independent
obligation from the other obligations of the Company under this Indenture and
the Notes; (ii) shall give rise to a separate and independent cause of action
against the Company; (iii) shall apply irrespective of any waiver granted by any
Holder of the Notes or the Trustee from time to time; and (iv) shall continue in
full force and effect notwithstanding any other judgment, order, claim or proof
of claim for a liquidated amount in respect of any sum due under the Notes or
this Indenture or any other judgment or order.

            Section 10.8. Legal Holidays. A "Legal Holiday" is a Saturday, a
Sunday or other day on which commercial banking institutions are authorized or
required to be closed in New York City. If a payment date is a Legal Holiday,
payment shall be made on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period. If a regular record
date is a Legal Holiday, the record date shall not be affected.

            Section 10.9. Governing Law, etc. THIS INDENTURE AND THE NOTES SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO
THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY. THE PARTIES HERETO EACH HEREBY WAIVE ANY RIGHT TO TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS INDENTURE OR THE NOTES OR ANY TRANSACTION RELATED HERETO OR THERETO.

            Section 10.10. No Recourse Against Others. An incorporator,
director, officer, employee, stockholder or controlling person, as such, of the
Company shall not have any liability for any obligations of the Company under
the Notes, this Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. By accepting a Note, each Holder shall
waive and release all such liability. The waiver and release shall be part of
the consideration for the issue of the Notes.

            Section 10.11. Successors. All agreements of the Company in this
Indenture and the Notes shall bind its successors. All agreements of the Trustee
in this Indenture shall bind its successors.

            Section 10.12. Duplicate and Counterpart Originals. The parties may
sign any number of copies of this Indenture. One signed copy is enough to prove
this Indenture. This Indenture may be executed in any number of counterparts,
each of which so executed shall be an original, but all of them together
represent the same agreement.

            Section 10.13. Severability. In case any provision in this Indenture
or in the Notes 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 10.14. Qualification of Indenture. The Company shall qualify
this Indenture under the TIA in accordance with the terms and conditions of the
Registration Agreement and shall pay all reasonable costs and expenses
(including attorneys' fees and expenses for the Company, the Trustee and the
Holders) incurred in connection therewith, including, but not limited to, costs
and expenses of qualification of this Indenture and the Notes and printing this
Indenture and the Notes. The Trustee shall be entitled to receive from the
Company any such Officers' Certificates, Opinions of Counsel or other
documentation as it may reasonably request in connection with any such
qualification of this Indenture under the TIA.

            Section 10.15. Table of Contents; Headings. The table of contents
and headings of the Articles and Sections of this Indenture have been inserted
for convenience of reference only, are not intended to be considered a part
hereof and shall not modify or restrict any of the terms or provisions hereof.

            Section 10.16. Agent for Service; Submission to Jurisdiction; Waiver
of Immunities.

            The Company agrees that any suit, action or proceeding against the
Company brought by any Holder or the Trustee arising out of or based upon this
Indenture or the Notes may be instituted in any state or federal court in the
Borough of Manhattan, The City of New York, New York, United States, any court
of competent jurisdiction in Bermuda or England and Wales and any appellate
court from any thereof. The Company hereby irrevocably submits to the
non-exclusive jurisdiction of such courts for such purpose and waives, to the
fullest extent permitted by law, trial by jury and any objection it may now or
hereafter have to the laying of venue of any such proceeding, and any claim it
may now or hereafter have that any proceeding in any such court is brought in an
inconvenient forum. The Company has appointed FLAG Telecom Holdings Ltd., 570
Lexington Avenue, New York, New York 10020 as its authorized agent (the
"Authorized Agent") upon whom all writs, process and summonses may be served in
any suit, action or proceeding arising out of or based upon this Indenture or
the Notes which may be instituted in any state or federal court in the Borough
of Manhattan, The City of New York, New York. The Company hereby represents and
warrants that the Authorized Agent has accepted such appointment and has agreed
to act as said agent for service of process, and the Company agrees to take any
and all action, including the filing of any and all documents, that may be
necessary to continue each such appointment in full force and effect as
aforesaid so long


                                       81
<PAGE>

as the Notes remain outstanding. The Company agrees that the appointment of the
Authorized Agent shall be irrevocable so long as any of the Notes remain
outstanding or until the irrevocable appointment by the Company of a successor
agent in The City of New York, New York as its authorized agent for such purpose
and the acceptance of such appointment by such successor. Service of process
upon the Authorized Agent shall be deemed, in every respect, effective service
of process upon the Company.

            To the extent that the Company has or hereafter may acquire any
immunity (sovereign or otherwise) from any legal action, suit or proceeding,
from jurisdiction of any court or from set-off or any legal process (whether
service or notice, attachment in aid or otherwise) with respect to itself or any
of its property, the Company hereby irrevocably waives and agrees not to plead
or claim such immunity in respect of its obligations under this Indenture or the
Notes.

            Nothing in this Section 10.16 shall affect the right of the Trustee
or any Holder of the Notes to serve process in any other manner permitted by
law.

                       11.625% Senior Euro Notes Due 2010

1. Interest

            FLAG Telecom Holdings Limited, a Bermuda corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown above.

            The Company will pay interest semiannually in arrears on each
Interest Payment Date of each year commencing September 30, 2000. Interest on
the Notes will accrue from the most recent date to which interest has been paid
on the Notes or, if no interest has been paid, from the Issue Date. The Company
shall pay interest on overdue principal (plus interest on such interest to the
extent lawful), at the rate borne by the Notes to the extent lawful. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

            The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal and, to the extent
such payments are lawful, interest on overdue installments of interest
("Defaulted Interest") without regard to any applicable grace periods at the
rate of 2.0% per annum in excess of the rate shown on this Note, as provided in
the Indenture.

            All payments made by the Company in respect of the Notes will be
made free and clear of and without deduction or withholding for or on account of
any Taxes imposed or levied by or on behalf of any Taxing Authority, unless such
withholding or deduction is required by law or by the interpretation or
administration thereof. In that event, the Company will pay to each Holder of
the Notes Additional Amounts as provided in the Indenture subject to the
limitations set forth in the Indenture.



2. Method of Payment

            By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Note is due and payable, the Company shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal and/or interest. The Company will pay interest (except Defaulted
Interest) to the Persons who are registered Holders of Notes at the close of
business on the Record Date preceding the Interest Payment Date even if Notes
are canceled, repurchased or redeemed after the Record Date and on or before the
relevant Interest Payment Date. Holders must surrender Notes to a Paying Agent
to collect principal payments. The Company will pay principal and interest in
Euros.

            The Notes will be payable as to principal, premium, if any, and
interest (including Additional Amounts, if any) in Euros at the offices or
agencies of the Company maintained for such purposes within the Borough of
Manhattan, The City of New York, New York and London, England or, at the option
of the Company, payment of interest may be made by check mailed to

York, 101 Barclay Street, Floor 21 West, New York, New York, 10286 and The Bank

            The Trustee will act as principal Paying Agent and Registrar at its
office in the City of New York, New York and as Paying Agent at its office in

            Change Of Control Offer. Upon the occurrence of a Change of Control,

all or a portion (in integral multiples of Euro 1,000) of the Holder's Notes at
a purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest through the date of purchase. Within 30 days following the date
upon which the Change of Control occurred, the Company must send, by first-class
mail, a notice to each Holder of Notes, with a copy to the Trustee, offering to

Offer"). The Change of Control Offer shall state, among other things, the
purchase date, which must be no earlier than 30 days nor later than 60 days from

reinvest the proceeds of such Asset Sale in a Permitted Business, use such
proceeds to retire debt, or to make an Asset Sale Offer to purchase a certain
amount of each Holder's Notes at 100% of the principal amount thereof, plus
accrued interest (if any) to the Asset Sale Offer Payment Date, as more fully
set forth in the Indenture.

denominations of principal amount of Euro 1,000 and any integral multiple
thereof. A Holder may transfer or exchange Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes and fees
required by law or permitted by the Indenture. The Registrar need not register
the transfer of or exchange (i) any Notes selected for redemption (except, in
the case of a Note to be redeemed in part, the portion of the Note not to be
redeemed) for a period beginning 15 days before the mailing of a notice of Notes
to be redeemed and ending on the date of such mailing or (ii) any Notes for a
period beginning 15 days before an interest payment date and ending on such

<PAGE>

9. Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

10. Discharge Prior to Redemption or Maturity

            Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the Notes
and the Indenture if the Company deposits with the Trustee Euros or European
Union Obligations for the payment of principal of and interest on the Notes to
redemption or maturity, as the case may be.

11. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Notes may be amended with the written consent of the Holders of
at least a majority in principal amount of the then Outstanding Notes and (ii)
any default (other than with respect to nonpayment or in respect of a provision
that cannot be amended without the written consent of each Holder affected) or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in principal amount of the then Outstanding Notes. Subject
to certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Notes to,
among other things, cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated Notes
in addition to or in place of certificated Notes, or to add guarantees with
respect to the Notes or to secure the Notes, or to add additional covenants or
surrender rights and powers conferred on the Company, or to comply with any
request of the SEC in connection with qualifying the Indenture under the Act, or
to make any change that does not adversely affect the rights of any Holder, or
to provide for the issuance of Exchange Notes.

12. Defaults and Remedies

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes may declare all the
Notes to be due and payable immediately. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Notes being due and
payable immediately upon the occurrence of such Events of Default.

            Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Notes unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the
Outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing Default or Event
of Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

the owner or pledgee of Notes and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

14. No Recourse Against Others

            An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of or by reason of such obligations or their creation. By
accepting a Note, each Holder waives and releases all such liability. The waiver
and release are part of the consideration for the issue of the Notes.

has directed the Trustee to use ISIN numbers in notices of redemption as a
convenience to Holders. No representation is made as to the accuracy of such
numbers either as printed on the Notes or as contained in any notice of
redemption and reliance may be placed only on the other identification numbers
placed thereon.

            This Note shall be governed by, and construed in accordance with,
the laws of the State of New York, but without giving effect to applicable
principles of conflicts of law to the extent that the application of the law of
another jurisdiction would be required thereby.

payable by the Company under or in connection with the Notes or the Indenture,
including damages. The

inconvenient forum. The Company has appointed FLAG Telecom Holdings Ltd. as its
authorized agent upon whom all writs, process and summonses may be served in any
suit, action or proceeding arising out of or based upon the Indenture or the

any legal process (whether service or notice, attachment in aid or otherwise)
with respect to itself or any of its property, the Company has irrevocably
waived and agreed not to plead or claim such immunity in respect of its
obligations under the Indenture or the Notes.

Such Indebtedness shall be deemed to have been Incurred at the time such Person
becomes a Restricted Subsidiary or at the time it merges or consolidates with

maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.7. The
Company may act as Paying Agent, Registrar, co-Registrar or transfer agent.

            (c) The Company initially appoints the Trustee at its principal
corporate trust office in the Borough of Manhattan, City of New York (the
"Corporate Trust Office") as Registrar, Paying Agent and agent for service of
demands and notices in connection with the Notes and this Indenture, until such
time as another Person is appointed as such.

            Section 2.4. Paying Agent to Hold Money in Trust. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that such
Paying Agent shall hold in trust for the benefit of Holders or the Trustee all
money held by such Paying Agent for the payment of principal of or interest on
the Notes and shall notify the Trustee in writing of any default by the Company
in making any such payment. If the Company or an Affiliate of the Company acts
as Paying Agent, it shall segregate the money held by it as Paying Agent and
hold it as a separate trust fund. The Company at any time may require a Paying
Agent (other than the Trustee) to pay all money held by it to the Trustee and to
account for any funds disbursed by such Paying Agent. Upon complying with this
Section 2.4, the Paying Agent (if other than the Company) shall have no further
liability for the money delivered to the Trustee. Upon any


                                       29
<PAGE>

proceeding under any Bankruptcy Law with respect to the Company or any Affiliate
of the Company, if the Company or such Affiliate is then acting as Paying Agent,
the Trustee shall replace the Company or such Affiliate as Paying Agent.

            Section 2.5. Holder Lists. The Trustee shall preserve in as current
a form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, or to the
extent otherwise required under the TIA, the Company shall furnish to the
Trustee, in writing at least seven Business Days before each Interest Payment
Date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Holders.

            Section 2.6. Global Note Provisions.

            (a) Each Global Note initially shall: (i) be registered in the name
of DTC or the nominee of DTC, (ii) be delivered to the Note Custodian, and (iii)
bear the appropriate legend, as set forth in Section 2.7 and Exhibit A. Any
Global Note may be represented by more than one certificate. The aggregate
principal amount of each Global Note may from time to time be increased or
decreased by adjustments made on the records of the Note Custodian, as provided
in this Indenture.

            (b) Members of, or participants in, DTC ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note held on their
behalf by DTC or by the Note Custodian under such Global Note, and DTC may be
treated by the Company, the Trustee, the Paying Agent and the Registrar and any
of their agents as the absolute owner of such Global Note for all purposes
whatsoever (except with respect to determination of Additional Amounts).
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee, the Paying Agent or the Registrar or any of their agents from giving
effect to any written certification, proxy or other authorization furnished by
DTC or impair, as between DTC and its Agent Members, the operation of customary
practices of DTC governing the exercise of the rights of an owner of a
beneficial interest in any Global Note. The registered Holder of a Global Note
may grant proxies and otherwise authorize any person, including Agent Members
and persons that may hold interests through Agent Members, to take any action
that a Holder is entitled to take under this Indenture or the Notes.

            (c) Except as provided below, owners of beneficial interests in
Global Notes will not be entitled to receive Certificated Notes. Certificated
Notes shall be issued to all owners of beneficial interests in a Global Note in
exchange for such interests if:

            (i) DTC notifies the Company that it is unwilling or unable to
      continue as depositary for such Global Note or DTC ceases to be a clearing
      agency registered under the Exchange Act, at a time when DTC is required
      to be so registered in order to act as depositary, and in each case a
      successor depositary is not appointed by the Company within 90 days of
      such notice,

            (ii) the Company executes and delivers to the Trustee and Registrar
      an Officers' Certificate stating that such Global Note shall be so
      exchangeable, or


                                       30
<PAGE>

            (iii) an Event of Default has occurred and is continuing and the
      Registrar has received a request from DTC.

In connection with the exchange of an entire Global Note for Certificated Notes
pursuant to this paragraph (c), such Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
upon Company Order the Trustee shall authenticate and deliver, to each
beneficial owner identified by DTC in exchange for its beneficial interest in
such Global Note, an equal aggregate principal amount of Certificated Notes of
authorized denominations.

            (d) In the event of the occurrence of the events specified in
Section 2.6(c), the Company will promptly make available to the Trustee a
reasonable supply of certificated Notes in definitive, fully registered form
without interest coupons.

            Section 2.7. Legends.

            (a) Each Global Note shall bear the legend specified therefor in
Exhibit A on the face thereof.

            (b) Each Restricted Note shall bear the private placement legend
specified therefor in Exhibit A on the face thereof (together with, if
applicable, the legend specified in paragraph (c) of this Section 2.7, the
"Private Placement Legend").

            (c) Each Certificated Note that is a Restricted Note shall bear the
legend specified therefor in Exhibit A on the face thereof.

            Section 2.8. Transfer and Exchange.

            (a) If (1) the owner of a beneficial interest in a Rule 144A Global
Note that is a Restricted Note wishes to transfer such interest (or portion
thereof) to a Non-U.S. Person pursuant to Regulation S and (2) such Non-U.S.
Person wishes to hold its interest in the Notes through a beneficial interest in
the Regulation S Global Note, (x) upon receipt by the Note Custodian and
Registrar of:

                        (A) instructions from the Holder of the Rule 144A Global
                  Note directing the Note Custodian and Registrar to credit or
                  cause to be credited a beneficial interest in the Regulation S
                  Global Note equal to the principal amount of the beneficial
                  interest in the Rule 144A Global Note to be transferred, and

                        (B) a certificate in the form of Exhibit C from the
                  transferor,

and (y) subject to the rules and procedures of DTC, the Note Custodian and
Registrar shall increase the Regulation S Global Note and decrease the Rule 144A
Global Note by such amount in accordance with the foregoing.


                                       31
<PAGE>

            (b) If the owner of an interest in a Regulation S Global Note wishes
to transfer such interest (or any portion thereof) to a QIB pursuant to Rule
144A prior to the expiration of the Distribution Compliance Period therefor, (x)
upon receipt by the Note Custodian and Registrar of:

                        (A) instructions from the Custodian and Holder of the
                  Regulation S Global Note directing the Note Registrar to
                  credit or cause to be credited a beneficial interest in the
                  Rule 144A Global Note equal to the principal amount of the
                  beneficial interest in the Regulation S Global Note to be
                  transferred, and

                        (B) a certificate in the form of Exhibit B duly executed
                  by the transferor,

and (y) in accordance with the rules and procedures of DTC, the Note Custodian
and Registrar shall increase the Rule 144A Global Note and decrease the
Regulation S Global Note by such amount in accordance with the foregoing.

            (c) Other Transfers. Any transfer of Restricted Notes not described
above (other than a transfer of a beneficial interest in a Global Note that does
not involve an exchange of such interest for a Certificated Note or a beneficial
interest in another Global Note, which must be effected in accordance with
applicable law and the rules and procedures of DTC, but is not subject to any
procedure required by this Indenture) shall be made only upon receipt by the
Registrar of such opinions of counsel, certificates and/or other information
reasonably required by and satisfactory to it in order to ensure compliance with
the Securities Act or in accordance with paragraph (d) of this Section 2.8.

            (d) Use and Removal of Private Placement Legends. Upon the transfer,
exchange or replacement of Notes (or beneficial interests in a Global Note) not
bearing a Private Placement Legend, the Note Custodian and Registrar shall
exchange such Notes (or beneficial interests) for beneficial interests in a
Global Note (or Certificated Notes if they have been issued pursuant to Section
2.6(c)) that does not bear a Private Placement Legend. Upon the transfer,
exchange or replacement of Notes (or beneficial interests in a Global Note)
bearing a Private Placement Legend, the Note Custodian and Registrar shall
deliver only Notes (or beneficial interests in a Global Note) that bear a
Private Placement Legend unless:

            (i) such Notes (or beneficial interests) are exchanged in a
      Registered Exchange Offer;

            (ii) such Notes (or beneficial interests) are transferred pursuant
      to a Registration Statement;

            (iii) such Notes (or beneficial interests) are transferred pursuant
      to Rule 144 upon delivery to the Registrar of a certificate of the
      transferor in the form of Exhibit D and an Opinion of Counsel reasonably
      satisfactory to the Registrar;

            (iv) such Notes (or beneficial interests) are transferred, replaced
      or exchanged after the Resale Restriction Termination Date therefor; or


                                       32
<PAGE>

            (v) in connection with such transfer, exchange or replacement the
      Registrar shall have received an Opinion of Counsel and other evidence
      reasonably satisfactory to it to the effect that neither such Private
      Placement Legend nor the related restrictions on transfer are required in
      order to maintain compliance with the provisions of the Securities Act.

The Private Placement Legend on any Note shall be removed at the request of the
Holder on or after the Resale Restriction Termination Date therefor. The Holder
of a Global Note may exchange an interest therein for an equivalent interest in
a Global Note not bearing a Private Placement Legend (other than a Regulation S
Global Note) upon transfer of such interest pursuant to any of clauses (i)
through (v) of this paragraph (e). The Company shall deliver to the Trustee an
Officers' Certificate promptly upon effectiveness, withdrawal or suspension of
any Registration Statement.

            (e) Consolidation of Global Notes and Exchange of Certificated Notes
for Beneficial Interests in Global Notes. If a Global Note not bearing a Private
Placement Legend (other than a Regulation S Global Note) is Outstanding at the
time of a Registered Exchange Offer, any interests in a Global Note exchanged in
such Registered Exchange Offer shall be exchanged for interests in such
Outstanding Global Note.

            (f) Retention of Documents. The Registrar shall retain copies of all
letters, notices and other written communications received pursuant to this
Article II. The Company shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
upon the giving of reasonable written notice to the Registrar.

            (g) Execution, Authentication of Notes, etc.

            (i) Subject to the other provisions of this Section 2.8, when Notes
      are presented to the Registrar or a co-Registrar with a request to
      register the transfer of such Notes or to exchange such Notes for an equal
      principal amount of Notes of other authorized denominations, the Registrar
      or co-Registrar shall register the transfer or make the exchange as
      requested if its requirements for such transaction are met; provided that
      any Notes presented or surrendered for registration of transfer or
      exchange shall be duly endorsed or accompanied by a written instrument of
      transfer in form satisfactory to the Registrar or co-Registrar, duly
      executed by the Holder thereof or his attorney duly authorized in writing.
      To permit registrations of transfers and exchanges and subject to the
      other terms and conditions of this Article II, the Company will execute
      and upon Company Order the Trustee will authenticate Certificated Notes
      and Global Notes at the Registrar's or co-Registrar's request. In
      accordance with the Registration Agreement, the Company will execute and
      upon Company Order the Trustee will authenticate Exchange Notes or Private
      Exchange Notes, as the case may be in exchange for Notes.

            (ii) No service charge shall be made to a Holder for any
      registration of transfer or exchange, but the Company may require payment
      of a sum sufficient to cover any transfer tax, assessments, or similar
      governmental charge payable in connection therewith (other than any such
      transfer taxes, assessments or similar governmental


                                       33
<PAGE>

      charges payable upon exchange or transfer pursuant to a Registered
      Exchange Offer, or Sections 5.1, 3.8, 3.15 or 9.5).

            (iii) The Registrar or co-Registrar shall not be required to
      register the transfer of or exchange of any Note for a period beginning:
      (1) 15 days before the mailing of a notice of an offer to repurchase or
      redeem Notes and ending at the close of business on the day of such
      mailing or (2) 15 days before an Interest Payment Date and ending on such
      Interest Payment Date.

            (iv) Prior to the due presentation for registration of transfer of
      any Note, the Company, the Trustee, the Paying Agent, the Registrar or any
      co-Registrar may deem and treat the person in whose name a Note is
      registered as the absolute owner of such Note for the purpose of receiving
      payment of principal of and interest on such Note and for all other
      purposes whatsoever, whether or not such Note is overdue, and none of the
      Company, the Trustee, the Paying Agent, the Registrar or any co-Registrar
      shall be affected by notice to the contrary.

            (v) All Notes issued upon any transfer or exchange pursuant to the
      terms of this Indenture shall evidence the same debt and shall be entitled
      to the same benefits under this Indenture as the Notes surrendered upon
      such transfer or exchange.

            (h) No Obligation of the Trustee.

            (i) The Trustee shall have no responsibility or obligation to any
      beneficial owner of interest in a Global Note, a member of, or a
      participant in, DTC or other Person with respect to the accuracy of the
      records of DTC or its nominee or of any participant or member thereof,
      with respect to any ownership interest in the Notes or with respect to the
      delivery to any participant, member, beneficial owner or other Person
      (other than DTC) of any notice (including any notice of redemption) or the
      payment of any amount or delivery of any Notes (or other security or
      property) under or with respect to such Notes. All notices and
      communications to be given to the Holders and all payments to be made to
      Holders in respect of the Notes shall be given or made only to or upon the
      order of the registered Holders (which shall be DTC or its nominee in the
      case of a Global Note). The Trustee may rely and shall be fully protected
      in relying upon information furnished by DTC with respect to its members,
      participants and any beneficial owners.

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

            Section 2.9. Mutilated, Destroyed, Lost or Stolen Notes.

            (a) If a mutilated Note is surrendered to the Registrar or if the
Holder of a Note claims that the Note has been lost, destroyed or wrongfully
taken, the Company shall execute and upon Company Order the Trustee shall
authenticate a replacement Note if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such
Holder shall furnish an affidavit of loss and indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-Registrar from any loss that any of them
may suffer if a Note is replaced, and, in the absence of notice to the Company
or the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
make available for delivery, in exchange for any such mutilated Note or in lieu
of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, bearing a number not contemporaneously Outstanding.

            (b) Upon the issuance of any new Note under this Section 2.9, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

            (c) Every new Note issued pursuant to this Section 2.9 in exchange
for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, shall
constitute an original additional contractual obligation of the Company and any
other obligor upon the Notes, whether or not the mutilated, destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

            Section 2.10. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may execute and upon Company Order the Trustee will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of definitive Notes but may have variations that the Company considers
appropriate for temporary Notes. Without unreasonable delay, the Company will
prepare and execute and upon Company Order the Trustee will authenticate
definitive Notes. After the preparation of definitive Notes, the temporary Notes
will be exchangeable for definitive Notes upon surrender of the temporary Notes
at any office or agency maintained by the Company for that purpose and such
exchange shall be without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Notes, the Company will execute and upon Company
Order the Trustee will authenticate and make available for delivery in exchange
therefor one or more definitive Notes representing an equal principal amount of
Notes. Until so exchanged, the Holder of temporary Notes shall in all respects
be entitled to the same benefits under this Indenture as a Holder of definitive
Notes.

            Section 2.11. Cancellation. The Company at any time may deliver
Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel and
dispose of cancelled Notes in accordance with its policy of disposal or return
to the Company all Notes surrendered for registration of transfer, exchange,
payment or


                                       35
<PAGE>

cancellation. The Company may not issue new Notes to replace Notes it has paid
or delivered to the Trustee for cancellation for any reason other than in
connection with a transfer or exchange upon Company Order.

            Section 2.12. Defaulted Interest. When any installment of interest
becomes Defaulted Interest, such installment shall forthwith cease to be payable
to the Holders in whose names the Notes were registered on the Record Date
applicable to such installment of interest. Defaulted Interest (including any
interest on such Defaulted Interest) may be paid by the Company, at its
election, as provided in clause (A) or (B) below.

            (A) The Company may elect to make payment of any Defaulted Interest
      (including any interest on such Defaulted Interest) to the Holders in
      whose names the Notes are registered at the close of business on a special
      record date for the payment of such Defaulted Interest (a "Special Record
      Date"), which shall be fixed in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest proposed
      to be paid and the date of the proposed payment, and at the same time the
      Company shall deposit with the Trustee an amount of money equal to the
      aggregate amount proposed to be paid in respect of such Defaulted Interest
      or shall make arrangements satisfactory to the Trustee for such deposit
      prior to the date of the proposed payment, such money when deposited to be
      held in trust for the benefit of the Holders entitled to such Defaulted
      Interest as provided in this clause (A). Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be not more than 15 calendar days and not less than ten calendar
      days prior to the date of the proposed payment and not less than ten
      calendar days after the receipt by the Trustee of the notice of the
      proposed payment. The Trustee shall promptly notify the Company of such
      Special Record Date and, in the name and at the expense of the Company,
      shall cause notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor to be sent, first-class mail, postage
      prepaid, to each Holder at such Holder's address as it appears in the
      registration books of the Registrar, not less than ten calendar days prior
      to such Special Record Date. Notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor having been mailed
      as aforesaid, such Defaulted Interest shall be paid to the Holders in
      whose names the Notes are registered at the close of business on such
      Special Record Date and shall no longer be payable pursuant to the
      following clause (B).

            (B) Alternatively, the Company may make payment of any Defaulted
      Interest (including any interest on such Defaulted Interest) in any other
      lawful manner not inconsistent with the requirements of any securities
      exchange on which the Notes may be listed, and upon such notice as may be
      required by such exchange, if, after notice given by the Company to the
      Trustee of the proposed payment pursuant to this clause (B), such manner
      of payment shall be deemed practicable by the Trustee.

            Section 2.13. Additional Interest Under Registration Agreements.
Under certain circumstances, the Company may be obligated to pay additional
interest to Holders, all as and to the extent set forth in the Registration
Agreement. The terms thereof are hereby incorporated herein by reference and
such additional interest is deemed to be interest for purposes of this
Indenture.

                                    COVENANTS

            Section 3.1. Payment of Notes.

            (a) The Company shall pay the principal of and interest (including
Defaulted Interest) on the Notes in U.S. Legal Tender on the dates and in the
manner provided in the Notes and in this Indenture. By at least 10:00 a.m. (New
York City time) on the date on which any principal of or interest on any Note is
due and payable, the Company shall irrevocably deposit with the Trustee or the
Paying Agent in immediately available funds U.S. Legal Tender sufficient to make
cash payments due on such Interest Payment Date or Maturity Date, as the case
may be. If the Company or an Affiliate of the Company is acting as Paying Agent,
the Company or such Affiliate shall, prior to 10:00 a.m. on each Interest
Payment Date and the Maturity Date, segregate and hold in trust U.S. Legal
Tender sufficient to make cash payments due on such Interest Payment Date or
Maturity Date, as the case may be. Principal and interest shall be considered
paid on the date due if on such date the Trustee or the Paying Agent (other than
the Company or an Affiliate of the Company) holds in accordance with this
Indenture U.S. Legal Tender designated for and sufficient to pay all principal
and interest then due and the Trustee or the Paying Agent, as the case may be,
is not prohibited from paying such money to the Holders on that date pursuant to
the terms of this Indenture.

            (b) Notwithstanding anything to the contrary contained in this
Indenture, the Company may, to the extent it is required to do so by law, deduct
or withhold income or other similar taxes imposed by the United States of
America from principal or interest payments hereunder.

            Section 3.2. Maintenance of Office or Agency.

            (a) The Company shall maintain each office or agency required under
Section 2.3. The Company will give prompt written notice to the Trustee of any
change in the location of any such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

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

            Section 3.3. Corporate Existence. Subject to Article IV, the Company
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence.

            Section 3.4. Payment of Taxes and Other Claim. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Restricted Subsidiary or for which it or any of
them are otherwise liable, or upon the income, profits or property of the
Company or any Restricted Subsidiary and (ii) all lawful claims for labor,
materials and supplies, which, if unpaid, might by law become a liability or
Lien upon the property of the Company or any Restricted Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which appropriate reserves, if necessary (in the good faith
judgment of management of the Company), are being maintained in accordance with
GAAP or where the failure to effect such payment will not be disadvantageous to
the Holders.

            Section 3.5. Compliance Certificate. (a) The Company shall deliver
to the Trustee within 90 days after the end of each fiscal year of the Company,
commencing with fiscal year 2000, an Officers' Certificate stating that in the
course of the performance by the signers of their duties as Officers of the
Company they would normally have knowledge of any Default or Event of Default
and whether or not the signers know of any Default or Event of Default that
occurred during such period. If they do, the certificate shall describe the
Default or Event of Default, its status and what action the Company is taking or
proposes to take with respect thereto. The Company also shall comply with TIA
ss. 314(a)(4).

            (b) So long as not contrary to the then current recommendations of
the American Institute of Certified Public Accountants or to the policies of the
Company's independent accountants, the annual Officers' Certificate delivered
pursuant to this Section 3.5 to the Trustee shall be accompanied by a written
report of the Company's independent accountants (who shall be a firm of
established national reputation) that in conducting their audit of the financial
statements of the Company for the most recent fiscal year nothing has come to
their attention that would lead them to believe that a Default or Event of
Default under this Indenture has occurred insofar as they relate to accounting
matters or, if any such violation has occurred, specifying the nature and period
of existence thereof, it being understood that such accountants shall not be
liable directly or indirectly to any Person for any failure to obtain knowledge
of any such violation that would not be disclosed in the course of an audit
examination conducted in accordance with GAAP.

            Section 3.6. Further Instruments and Acts. The Company will execute
and deliver such further instruments and do such further acts as may be
reasonably necessary or proper or as the Trustee may reasonably request to carry
out more effectively the purpose of this Indenture.

            Section 3.7. Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay or extension law or any usury law or other law that
would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Notes as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture. The Company hereby expressly waives (to the
extent that it may lawfully do so)


                                       38
<PAGE>

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.

            Section 3.8. Change Of Control.

            (a) Upon the occurrence of a Change of Control, each Holder of Notes
will have the right to require that the Company purchase all or a portion (in
integral multiples of $1,000) of the Holder's Notes at a purchase price equal to
101% of the principal amount thereof, plus accrued and unpaid interest through
the date of purchase (the "Change of Control Payment").

            (b) Within 30 days following the date upon which the Change of
Control occurred, the Company must send a Change of Control Notice to each
Holder of Notes, with a copy to the Trustee, offering to purchase such Notes as
described above (a "Change of Control Offer"). The Change of Control Offer shall
state, among other things, the purchase date, which must be no earlier than 30
days nor later than 60 days from the date the notice is mailed, other than as
may be required by law (the "Change of Control Payment Date").

            (c) On the Change of Control Payment Date, the Company will, to the
extent lawful:

            (1) accept for payment all Notes or portions thereof properly
      tendered pursuant to a Change of Control Offer (or, if the Trustee is
      acting as agent for the Company, direct the Trustee to so accept);

            (2) deposit with the Paying Agent funds in an amount equal to the
      Change of Control Payment in respect of all Notes or portions thereof so
      tendered; and

            (3) deliver or cause to be delivered to the Trustee (including by
      designating the Trustee as its agent for acceptance of Notes) the Notes so
      accepted together with an Officers' Certificate stating the aggregate
      principal amount of Notes or portions thereof being purchased by the
      Company.

            (d) If only a portion of a Note is purchased pursuant to a Change of
Control Offer, a new Note in a principal amount equal to the portion thereof not
purchased will be issued in the name of the Holder thereof upon cancellation of
the original Note (or appropriate adjustments to the amount and beneficial
interests in the applicable Global Note will be made, as appropriate).

            (e) The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other applicable securities laws and regulations
in connection with the purchase of Notes in connection with any Change of
Control Offer. To the extent that the provisions of any securities laws or
regulations conflict with this Section 3.8, the Company will comply with the
applicable securities laws and regulations and will not be deemed to have
breached its obligations under such Indenture by doing so.

additional amounts ("Additional Amounts") as may be necessary in order that the
net amounts paid to such Holder who, with respect to any such tax, assessment or
other governmental charge, is not resident in, or a citizen of, such
jurisdiction, after deduction or withholding, shall be not less than the amount
specified in such Note to which such Holder is entitled; provided, however, the
Company or a successor corporation shall not be required to make any payment of
Additional Amounts for or on account of:

            (i) any tax, assessment or other governmental charge which would not
      have been imposed but for:

                  over, such Holder, if such Holder is an estate, trust,
                  partnership, limited liability company or corporation) and the

                  or possession thereof or area subject to its jurisdiction
                  (other than the mere receipt of such payment or the ownership
                  or holding of such Note), including, without limitation, such
                  Holder (or such fiduciary, settlor, beneficiary, member,

                  the

<PAGE>

                  date on which payment thereof is duly provided for, whichever

            (ii) any estate, inheritance, gift, sales, transfer, personal
      property or similar tax, assessment or other governmental charge; (iii)

      otherwise than by withholding from a payment of the principal of, premium,
      if any, or any interest on, the Notes;

            (iv) any tax, assessment or other governmental charge that is
      imposed or withheld by reason of the failure by the Holder or the
      beneficial owner of the Note to comply with a request of the Company
      addressed to the Holder:

            (x)   to provide information, documents or other evidence concerning
                  the nationality, residence or identity of the Holder or such
                  beneficial owner; or

            (y)   to make and deliver any declaration or other similar claim
                  (other than a claim for refund of a tax, assessment or other
                  governmental charge withheld by the Company) or satisfy any
                  information or reporting requirements,

which, in the case of (x) or (y), is required or imposed by a statute, treaty,
regulation or administrative practice of the taxing jurisdiction as a
precondition to exemption from all or part of such tax, assessment or other
governmental charge; or

            (v) any combination of items (i), (ii), (iii) and (iv) above, nor

of such payment to the extent such payment would be required by the laws of:

            (1) Bermuda or any political subdivision or governmental authority
      thereof or therein having the power to tax;

            (2) any jurisdiction, other than the United States, the United
      Kingdom or Luxembourg, from or through which payment on the Notes is made
      by the Company or a successor corporation, or its paying agent in its
      capacity as such, or any political subdivision or governmental authority
      thereof or therein having the power to tax; or

            (3) any other jurisdiction, other than the United States, in which
      the Company or a successor corporation is organized, or any political
      subdivision or governmental authority having the power to tax


                                       41
<PAGE>

to be included in the income for tax purposes of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership or limited liability
company or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the holder of such Note.

            (b) The Company shall provide the Trustee with the official
acknowledgment of the relevant taxing authority (or, if such acknowledgment is
not available, a certified copy thereof) evidencing the payment of the
withholding taxes, if any, by the Company. Copies of such documentation shall be
made available to the holders of the Notes or the Paying Agents, as applicable,
upon request therefor.

            Section 3.10. Limitation On Incurrence Of Additional Indebtedness
And Preferred Stock.

            (1) The Company will not, and will not cause or permit any
Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness,
including Acquired Indebtedness, or permit any Restricted Subsidiary to Incur
Preferred Stock, except that the Company may Incur Indebtedness, including
Acquired Indebtedness, and any Restricted Subsidiary may Incur Acquired
Indebtedness or Acquired Preferred Stock, if, at the time of and immediately
after giving pro forma effect to the Incurrence thereof and the application of
the proceeds therefrom:

            (a) the Consolidated Leverage Ratio is less than 6.0 to 1.0, or

            (b) Indebtedness Incurred by the Company to any Restricted
      Subsidiary or Indebtedness or Preferred Stock Incurred or issued by any
      Restricted Subsidiary to the Company or any Restricted Subsidiary
      (provided, however, that (x) upon a Disposition by a Restricted Subsidiary
      or the Company of any Indebtedness so Incurred to a Person other than the
      Company or another Restricted Subsidiary or (y) if for any reason a
      Restricted Subsidiary that is either an issuer or lender of such
      Indebtedness ceases to be a Restricted Subsidiary, the provisions of this
      clause (b) shall no longer be applicable to such Indebtedness); provided
      that any such Indebtedness of the Company shall be unsecured and
      subordinated in all respects to the Company's obligations pursuant to the
      Notes;

            (c) Indebtedness of the Company in an aggregate amount outstanding
      at any time of up to $50 million;

            (d) Indebtedness of the Company or any Restricted Subsidiary
      pursuant to any Permitted Credit Facility in an aggregate amount
      outstanding at any time pursuant to this clause (d) of up to $350 million,
      minus the amount of any such Indebtedness:


                                       42
<PAGE>

                  (x) permanently repaid with the Net Cash Proceeds from any
            Asset Sale pursuant to Section 3.15; or

                  (y) assumed by a transferee in an Asset Sale;

            (e) (x) Purchase Money Indebtedness of the Company in respect of

                  (y) Purchase Money Indebtedness of any Restricted Subsidiary
            in respect of Telecommunications Assets Incurred pursuant to any
            Permitted Credit Facility or Vendor Facility;

            (f) Hedging Obligations of the Company or any Restricted Subsidiary
      in respect of Indebtedness that is permitted by the terms of the relevant
      Indenture to be outstanding; provided that the notional amount of any such
      Hedging Obligation does not exceed the amount of Indebtedness to which
      such Hedging Obligation relates;

            (g) Indebtedness of the Company or any Restricted Subsidiary solely
      in respect of bankers acceptances, letters of credit and performance
      bonds, in each case Incurred in the ordinary course of business;

            (h) Permitted Refinancing Indebtedness; and

      Indebtedness"), other than Indebtedness described in clause 2(d) of this
      Section 3.10.

            (3) For purposes of determining compliance with, and the outstanding
principal amount of any particular Indebtedness Incurred pursuant to, and in
compliance with, this covenant, the amount of Indebtedness issued at a price
that is less than the principal amount thereof will be equal to the amount of
the liability in respect thereof determined in accordance with GAAP. Accrual of
interest, the accretion or amortization of original issue discount, the payment
of regularly scheduled interest in the form of additional Indebtedness of the
same instrument or the payment of regularly scheduled dividends on Disqualified
Stock in the form of additional Disqualified Stock with the same terms will not
be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.10.

            (4) The Company will not, directly or indirectly, Incur any
Indebtedness that is subordinate in right of payment to any other Indebtedness,
unless such Indebtedness is expressly subordinate in right of payment to the
Notes to the same extent and on the same terms as such Indebtedness is
subordinate to such other Indebtedness.

            Section 3.11. Limitation On Restricted Payments.

                  Company,

            Subsidiary at the time of the Revocation; and


                                       45
<PAGE>

this clause (7) that are at any time outstanding, does not exceed the sum of:

            (x) $50 million, plus

            (y) the amount then available for the making of Restricted Payments
pursuant to clause (3) of the preceding paragraph without giving effect to
subclause (A) thereof.

            Each Restricted Payment permitted pursuant to clauses (1), (4), (5),
(6) and (7) of this paragraph shall be included, and each Restricted Payment
permitted pursuant to clauses (2) and (3) of this paragraph shall be excluded
(except as specifically set forth in each such clause), for all purposes when
performing the calculation set forth in clause (3) of the first paragraph of
this Section 3.11.

            Section 3.12. Limitation on Designation of Unrestricted
Subsidiaries.

            (a) The Board of Directors may not designate a Subsidiary of the
Company (other than a newly created Subsidiary in which no Investment has
previously been made (other than any de minimus amount required to capitalize
such Subsidiary in connection with its organization)) as an Unrestricted
Subsidiary (a "Designation") if:

            (1) a Default or Event of Default shall have occurred and be
      continuing at the time of or after giving effect to such Designation, and

            (2) the Company would be prohibited under this Indenture from making
      a Restricted Investment at the time of such Designation (assuming the
      effectiveness of such Designation for purposes of this Section 3.12) in an
      amount equal to the Designation Amount (as defined below).

            (b) Any Designation shall be made by Board Resolution. In the event
of any such Designation, all outstanding Investments owned by the Company and
its Restricted Subsidiaries in the Subsidiary at Designation will be deemed to
be a Restricted Investment made as of the time of such Designation and will
reduce the amount available for Restricted Payments under the first or second
paragraph of this Section 3.12. All such outstanding Investments will be deemed
to constitute Restricted Payments in an amount equal to the Fair Market Value of
such Investments at the time of such Designation (the "Designation Amount").

            (c) A Designation may be revoked and an Unrestricted Subsidiary may
thus be redesignated as a Restricted Subsidiary (a "Revocation") by Board
Resolution, provided that the Company will not make any Revocation unless after
giving pro forma effect to such Revocation:

            (1) no Default or Event of Default shall have occurred and be
      continuing;


                                       47
<PAGE>

            (2) all Liens of such Unrestricted Subsidiary outstanding
      immediately following such Revocation would, if Incurred at such time,
      have been permitted to be Incurred at such time for all purposes under
      this Indenture; and

            (3) the Company could Incur $1 of additional Indebtedness pursuant
      to clause (1) Section 3.10.

            (d) Neither the Company nor any Restricted Subsidiary will at any
      time:

            (1) provide credit support for, subject any of its property or
      assets (other than the Capital Stock of any Unrestricted Subsidiary) to
      the satisfaction of, or guarantee, any Indebtedness of any Unrestricted
      Subsidiary (including any undertaking, agreement or instrument evidencing
      such Indebtedness);

            (2) be directly or indirectly liable for any Indebtedness of any
      Unrestricted Subsidiary; or

            (3) be directly or indirectly liable for any Indebtedness which
      provides that the holder thereof may (upon notice, lapse of time or both)
      declare a default thereon or cause the payment thereof to be accelerated
      or payable prior to its final scheduled maturity upon the occurrence of a
      default with respect to any Indebtedness of any Unrestricted Subsidiary,
      except for any non-recourse guarantee given solely to support the pledge
      by the Company or any Restricted Subsidiary of the Capital Stock of any
      Unrestricted Subsidiary.

            Section 3.13. Limitation on Liens.

            The Company will not, and will not cause or permit any Restricted
Subsidiary to, directly or indirectly, Incur or suffer to exist or become
effective any Liens of any kind (except for Permitted Liens) against or upon any
of their respective properties or assets, whether owned on the Issue Date or
acquired after the Issue Date, or any income, profits or proceeds therefrom,
unless contemporaneously therewith effective provision is made by the Company to
secure the Notes and all other amounts due under the relevant Indenture equally
and ratably with such Indebtedness with a Lien on the same properties and assets
securing such Indebtedness for so long as such Indebtedness is secured by such
Lien; provided, that no such Lien may secure Subordinated Indebtedness except as
permitted by clause 3(a) of the definition of "Permitted Liens."

            Section 3.14. Limitation On Dividend And Other Payment Restrictions
Affecting Restricted Subsidiaries.

            (a) Except as provided in clause (b) below, the Company will not,
and will not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or permit to exist or become effective any
encumbrance or restriction on the ability of any Restricted Subsidiary to:

            (1) pay dividends or make any other distributions on or in respect
      of its Capital Stock or with respect to any other interest or
      participation, or measured by its profits, to


                                       48
<PAGE>

      the Company or any other Restricted Subsidiary or pay any Indebtedness
      owed to the Company or any other Restricted Subsidiary;

            (2) make loans or advances to, or guarantee any Indebtedness or
      other obligations of, or make any Investment in, the Company or any other
      Restricted Subsidiary; or

            (3) transfer any of its property or assets to the Company or any
      other Restricted Subsidiary.

            (b) Clause (a) will not apply to encumbrances or restrictions
existing under or by reason of:

            (1) Existing Indebtedness as in effect on the Issue Date;

            (2) this Indenture and the Notes;

            (3) any Permitted Credit Facility or Vendor Facility, provided that:

            (a) the outstanding Indebtedness under such Permitted Credit
Facility or Vendor Facility does not exceed the amounts permitted under clause
2(d) or 2(e)(y), as the case may be, of Section 3.10, and

            (b) the Chief Financial Officer of the Company determines in good
faith that:

            (x) such encumbrances or restrictions are no more restrictive, taken
      as a whole, than those that would be contained in a credit agreement with
      terms that are commercially reasonable for a borrower engaged in a
      business comparable to the Company that has substantially comparable
      Indebtedness, and

            (y) any such restrictions will not materially affect the Company's
      ability to make principal, premium or interest payments on the Notes
      pursuant to the terms of this Indenture,

            (4) applicable law,

            (5) any instrument governing Indebtedness or Capital Stock of a
      Person or assets acquired by the Company or any of its Restricted
      Subsidiaries as in effect at the time of such acquisition (except to the
      extent such Indebtedness was Incurred in connection with or in
      contemplation of such acquisition), which encumbrances or restrictions are
      not applicable to any Person, or the properties or assets of any Person,
      other than the Person, or the property or assets of the Person, so
      acquired, provided that any such Indebtedness or Preferred Stock was
      permitted by the terms of this Indenture to be incurred,

            (6) customary non-assignment provisions in leases entered into in
      the ordinary course of business and consistent with past practices,

            (7) any agreement for the sale or other disposition of a Restricted
      Subsidiary that restricts distributions by that Restricted Subsidiary
      pending its sale or other disposition,


                                       49
<PAGE>

      provided that the consummation of such transaction would not result in a
      Default or Event of Default, that such restriction terminates if such
      transaction is not consummated and that the consummation or abandonment of
      such transaction occurs within one year of the date such agreement was
      entered into,

            (8) Permitted Refinancing Indebtedness, provided that the
      restrictions contained in the agreements governing such Permitted
      Refinancing Indebtedness are no more restrictive, taken as a whole, than
      those contained in the agreements governing the Indebtedness being
      Refinanced,

            (9) limitations on the right to dispose of assets subject to a Lien
      securing Indebtedness to the extent that such Lien is permitted to be
      Incurred pursuant to Section 3.13, and

            (10) provisions with respect to the disposition or distribution of
      assets or property in joint venture agreements and other similar
      agreements entered into in the ordinary course of business.

            Section 3.15 Limitation On Asset Sales.

            (a) The Company will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, consummate an Asset Sale unless:

            (i) the Company or the applicable Restricted Subsidiary, as the case
      may be, receives consideration at the time of the Asset Sale at least
      equal to the Fair Market Value of the assets sold or otherwise disposed
      of, and

            (ii) at least 75% of the consideration received for the assets
      disposed of by the Company or the Restricted Subsidiary, as the case may
      be, in the Asset Sale shall be in the form of:

            (1) cash or Cash Equivalents, or

            (2) (A) tangible or intangible assets to be used by the Company or
      any Restricted Subsidiary in the Telecommunications Business, or

            (B) Capital Stock of a Person engaged, except to a de minimis
      extent, solely in a Telecommunications Business that will become, upon
      purchase, a Restricted Subsidiary (collectively, "Replacement Assets"),

            (b) The Company or such Restricted Subsidiary, as the case may be,
may apply the Net Cash Proceeds of any such Asset Sale within 360 days of
receipt thereof to:

            (i) permanently repay or repurchase outstanding (without Refinancing
      and including a permanent reduction in commitments in the case of a
      revolving credit facility) (x) Indebtedness of the Company (other than
      Subordinated Indebtedness or Disqualified Stock) that is secured
      Indebtedness or which has a final maturity date prior to the final


                                       50
<PAGE>

      maturity date of the Notes or (y) Indebtedness (other than Disqualified
      Stock) of any Restricted Subsidiary, or

            (ii) purchase Replacement Assets from a Person other than the
      Company and its Subsidiaries.

            The balance of the Net Cash Proceeds that are not applied or
invested as described in the immediately preceding clauses (i) and (ii), shall
constitute "Excess Proceeds."

            (c) When the aggregate amount of Excess Proceeds equals or exceeds
$25 million, taking into account income earned on such Excess Proceeds, the
Company will be required to make a pro rata offer (an "Asset Sale Offer") to all
holders of Notes and of pari passu Indebtedness with comparable provisions
requiring such Indebtedness to be purchased with the proceeds of such Asset Sale
to purchase the maximum principal amount (or accreted value in the case of
Indebtedness issued with original issue discount) (the "Asset Sale Offer
Amount") of Notes and such pari passu Indebtedness that may be purchased with
the Excess Proceeds, at a purchase price in cash in an amount equal to 100% of
the principal amount thereof (or the accreted value thereof in the case of
Indebtedness issued with original issue discount) plus accrued and unpaid
interest or accretion thereon to the date of purchase, subject to the right of
holders on the relevant record date to receive interest due on the relevant
interest payment date, in accordance with the procedures set forth in the
Indenture and the agreements governing such pari passu Indebtedness. To the
extent that any Excess Proceeds remain after consummation of an Asset Sale
Offer, the Company may use such Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount (or accreted
values) of Notes and pari passu Indebtedness tendered into such Asset Sale Offer
surrendered by holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes and pari passu Indebtedness to be purchased on a
pro rata basis in proportion to the respective principal amounts (or accreted
values) of the Notes and such other Indebtedness. Upon completion of such Asset
Sale Offer, the amount of Excess Proceeds shall be reset at zero for purposes of
the first sentence of this paragraph.

            (d) Pending application in accordance with this Section 3.15, Net
Cash Proceeds may be applied to temporarily reduce revolving credit borrowings
which can be reborrowed or invested in Cash Equivalents. An Asset Sale Offer
Notice will be mailed first class, postage prepaid, to the record Holders as
shown on the register of Holders within 30 days following such 360th day, with a
copy to the Trustee offering to purchase the Notes as described above. Each
notice of an Asset Sale Offer shall state, among other things, the purchase
date, which must be no earlier than 30 days nor later than 60 days from the date
the notice is mailed, other than as may be required by law (the "Asset Sale
Offer Payment Date"). Upon receiving an Asset Sale Offer Notice, Holders may
elect to tender their Notes in whole or in part in integral multiples of $1,000
in exchange for cash.

            (e) On the Asset Sale Offer Payment Date, the Company will, to the
extent lawful:


                                       51
<PAGE>

            (1) accept for payment all Notes or portions thereof properly
      tendered pursuant to the Asset Sale Offer (or, if the Trustee is acting as
      agent for the Company, direct the Trustee to so accept);

            (2) deposit with the Paying Agent funds in an amount equal to the
      Asset Sale Offer Amount in respect of all Notes or portions thereof so
      tendered; and

            (3) deliver or cause to be delivered to the Trustee (including by
      designating the Trustee as its agent for acceptance of Notes) the Notes so
      accepted together with an Officers' Certificate stating the aggregate
      principal amount of Notes or portions thereof being purchased by the
      Company.

            (f) The Company will comply with the requirements of Rule 14e-1
under the Exchange Act and any other applicable securities laws in connection
with the purchase of Notes pursuant to an Asset Sale Offer. To the extent that
the provisions of any applicable securities laws or regulations conflict with
this Section 3.15, the Company shall comply with these laws and regulations and
shall not be deemed to have breached its obligations under this Section 3.15 by
doing so.

            (g) In the event of the transfer of substantially all (but not all)
of the property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 4.1 the surviving
entity shall be deemed to have sold the properties and assets of the Company and
its Restricted Subsidiaries not so transferred for purposes of this Section
3.15, and shall comply with the provisions of this Section 3.15 with respect to
the deemed sale as if it were an Asset Sale. In addition, the Fair Market Value
of properties and assets of the Company or its Restricted Subsidiaries so deemed
to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section
3.15.

            (h) If at any time any non-cash consideration received by the
Company or any Restricted Subsidiary, as the case may be, in connection with any
Asset Sale is converted into or sold or otherwise disposed of for cash (other
than interest received with respect to any non-cash consideration), the
conversion or disposition shall be deemed to constitute an Asset Sale hereunder
and the Net Cash Proceeds thereof shall be applied in accordance with this
Section 3.15 within 360 days of conversion or disposition.

            Section 3.16. Limitation On Transactions With Affiliates.

            (1) The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless:

            (a) such Affiliate Transaction is on terms that are not materially
less favorable to the Company or the relevant Restricted Subsidiary than those
that would have been obtained in a comparable transaction on an arm's length
basis by the Company or such Restricted Subsidiary with a Person that is not an
Affiliate, and


                                       52
<PAGE>

            (b) with respect to any Affiliate Transaction or series of related
Affiliate Transactions:

            (x) involving aggregate consideration in excess of $10 million, the
      Company delivers to the Trustee a resolution of the Board of Directors set
      forth in an Officers' Certificate that such Affiliate Transaction is
      approved by a majority of the disinterested members of the Board of
      Directors and certifying that such Affiliate Transaction complies with
      clause (a) above and is in the best interests of the Company or such
      Restricted Subsidiary, or

            (y) if involving aggregate consideration in excess of $25 million, a
      favorable written opinion as to the fairness to the Company of such
      Affiliate Transaction from a financial point of view is also obtained by
      the Company from an independent accounting, appraisal or investment
      banking firm of national standing and delivered to the Trustee.

            (2) Clause (1) will not apply to the following:

            (a) the entering into, maintaining or performance of any employment
contract, collective bargaining agreement, benefit plan, program or arrangement,
related trust agreement or any other similar arrangement for or with any
employee, officer or director of the Company or any Restricted Subsidiary
heretofore or hereafter entered into in the ordinary course of business,
including vacation, health, insurance, deferred compensation, retirement,
savings or other similar plans;

            (b) the payment of compensation, performance of indemnification or
contribution obligations, or an issuance, grant or award of stock, options, or
other equity-related interests or other securities, to employees, officers or
directors of the Company or any Restricted Subsidiary in the ordinary course of
business;

            (c) transactions between or among the Company and/or its Restricted
Subsidiaries;

            (d) payment of reasonable fees to directors of the Company;

            (e) any sale or other issuance of Capital Stock (other than
Disqualified Stock) of the Company;

            (f) Affiliate Transactions in effect or approved by the Board of
Directors on the Issue Date, including any amendments thereto; provided that the
terms of such amendments are not materially less favorable to the Company than
the terms of such agreement prior to such amendment;

            (g) Restricted Payments that are permitted by Section 3.11; and

            (h) (x) the Primary Supplier Agreement dated January 18, 2000
between Bell Atlantic Global Systems Company and the Company, including any
amendments thereto, provided that the terms of such amendments are not
materially less favorable to the Company than the terms of such agreements prior
to such amendment, or


                                       53
<PAGE>

            (y) any transaction with respect to capacity and/or the provision of
      telecommunications services between the Company or any Restricted
      Subsidiary and any Affiliates, provided that such transaction complies
      with clause (1)(a) of this Section 3.16.

            Section 3.17. Limitation On Business Activities.

            The Company will not, and will not permit any of its Restricted
Subsidiaries to, engage, to more than a de minimus extent, in any business other
than a Telecommunications Business.

            Section 3.18. Reports To Holders.

            Whether or not the Company is subject to the reporting requirements
of Section 13 or 15(d) of the Exchange Act, so long as any Notes remain
outstanding, the Company will:

            (1) provide the Trustee and the Holders with the annual reports and
information, documents and other reports as are specified in Sections 13 and
15(d) of the Exchange Act subject to such Sections within 15 days after the
times specified for the filing of the information, documents and reports under
such Sections; provided that, whether or not required under such Sections, the
Company shall provide quarterly financial statements (including a balance sheet,
income statement and cash flow statement and notes thereto) and "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
satisfying the requirements therefor established by the Commission; and

            (2) file with the Commission, to the extent permitted, the
information, documents and reports referred to in clause (1) within the periods
specified under such Sections; provided that the quarterly information specified
in clause (1) shall be filed within 45 days after the end of the relevant fiscal
quarter or such shorter time established by the Commission.

            At any time when the Company is not subject to or is not current in
its reporting obligations under clause (2) of the preceding paragraph, the
Company will make available, upon request, to any holder and any prospective
purchaser of Notes the information required pursuant to Rule 144A(d)(4) under
the Securities Act.

            interest payable as provided in Section 5.6,

                  (3) whether or not the Company is redeeming all Outstanding
            Notes,

                  (4) if the Company is not redeeming all Outstanding Notes, the
            aggregate principal amount of Notes that the Company is redeeming
            and the aggregate principal amount of Notes that will be Outstanding
            after the partial redemption, as well as the identification of the
            particular Notes, or portions of the particular Notes, that the
            Company is redeeming,

                  (5) if the Company is redeeming only part of a Note, the
            notice that relates to that Note shall state that on and after the
            Redemption Date, upon surrender of that Note, the Holder will
            receive, without charge, a new Note or Notes of authorized
            denominations for the principal amount of the Note remaining
            unredeemed,

                  (6) that on the Redemption Date the redemption price and any
            accrued interest payable to the Redemption Date as provided in
            Section 5.6 will become due and payable in respect of each Note, or
            the portion of each Note, to be redeemed, and, unless the Company
            defaults in making the redemption payment, that interest on each
            Note, or the portion of each Note, to be redeemed, will cease to
            accrue on and after the Redemption Date,

            Holder's Notes for payment of the redemption price, and

                  (8) the CUSIP or ISIN number, if any, listed in the notice or
            printed on the Notes, and that no representation is made as to the
            accuracy or correctness of such CUSIP or ISIN number.

            Section 5.4. Selection of Notes to Be Redeemed in Part. (a) If the
Company is not redeeming all Outstanding Notes, the Trustee shall select the
Notes to be redeemed in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not then listed on a national securities exchange, on a pro rata
basis, by lot or in another fair and reasonable manner chosen at the discretion
of the Trustee; provided, however, that if a partial redemption is made with the
proceeds of a Public Equity Offering, selection of the Notes, or portions of the
Notes, for redemption shall be made by the Trustee only on a pro rata basis as
is practicable (subject to the procedures of DTC, Euroclear or Clearstream,
Luxembourg, as the case may be), unless that method is prohibited. The Trustee
shall make the selection from the Outstanding Notes not previously called for
redemption. The Trustee shall promptly notify the Company in writing of the
Notes selected for redemption and, in the case of any Notes selected for partial
redemption, the principal amount of the Notes to be redeemed. In the event of a
partial redemption by lot, the Trustee shall select the particular Notes to be
redeemed not less than 30 nor more than 60 days prior to the relevant Redemption
Date from the Outstanding Notes not previously called for redemption. The
Company may redeem Notes in denominations of $1,000 only in whole. The Trustee
may select for redemption portions (equal to $1,000 or any integral multiple of
$1,000) of the principal of Notes that have denominations larger than $1,000.

            (b) For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Notes shall relate, in the
case of any Note redeemed or to be redeemed only in part, to the portion of the
principal amount of that Note which has been or is to be redeemed.

            Section 5.5. Deposit of Redemption Price. On or prior to 10 a.m. on
the relevant Redemption Date, the Company shall deposit with the Trustee or with
a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 2.4) an amount of money in immediately
available funds sufficient to pay the redemption price of, and accrued interest
on, all the Notes that the Company is redeeming on that date.

            Section 5.6. Notes Payable on Redemption Date. If the Company, or
the Trustee on behalf of the Company, gives notice of redemption in accordance
with this Article V, the Notes, or the portions of Notes, called for redemption,
shall, on the Redemption Date, become due and payable at the redemption price
specified in the notice (together with accrued and unpaid interest, if any, to
the Redemption Date), and from and after the Redemption Date (unless the Company
shall default in the payment of the redemption price and accrued interest) the
Notes or the portions of Notes shall cease to bear interest. Upon surrender of
any Note for redemption in accordance with the notice, the Company shall pay the
Notes at the redemption price, together with accrued and unpaid interest, if
any, to the Redemption Date (subject to the rights of Holders of record on the
relevant record date to receive interest due on the relevant Interest Payment
Date). If the Company shall fail to pay any Note called for redemption upon its
surrender for redemption, the principal shall, until paid, bear interest from
the Redemption Date at the rate borne by the Notes.

            Section 5.7. Unredeemed Portions of Partially Redeemed Note. Upon
surrender of a Note that is to be redeemed in part, the Company shall execute,
and the Trustee shall authenticate and make available for delivery to the Holder
of the Note at the expense of the


                                       57
<PAGE>

Company, a new Note or Notes, of any authorized denomination as requested by the
Holder, in an aggregate principal amount equal to, and in exchange for, the
unredeemed portion of the principal of the Note surrendered, provided that each
new Note will be in a principal amount of $1,000 or integral multiple of $1,000.

                                   ARTICLE VI

                              DEFAULTS AND REMEDIES

      amount of the Notes;

            (5) default by the Company or any Restricted Subsidiary under any
      Indebtedness which:

            (a) is caused by a failure to pay principal of or premium, if any,

      period; or

            (b) results in the acceleration of such Indebtedness prior to its
      Stated Maturity; and the principal amount of Indebtedness covered by (a)
      or (b) at the relevant time, aggregates $15 million or more.

            (6) failure by the Company or any of its Restricted Subsidiaries to

      solvent insurer of national or international reputation which has
      acknowledged its obligations in writing), aggregating $15 million or more,
      which judgment(s) are not paid, discharged or stayed for a period of 60
      days or more;


                                       58
<PAGE>

            (7) the entry by a court of competent jurisdiction of: (i) a decree

      of the affairs of the Company or any Restricted Subsidiary of the Company,
      and in each case, the continuance of any such decree or order for relief
      or any such other decree or order unstayed and in effect for a period of
      60 consecutive calendar days; or

            (8) (i) the commencement by the Company or any Restricted Subsidiary
      of the Company of a voluntary case or proceeding under any Bankruptcy Law
      or of any other case or proceeding to be adjudicated a bankrupt or
      insolvent, (ii) the consent by the Company or any Restricted Subsidiary of
      the Company to the entry of a decree or order for relief in respect of the
      Company or any Restricted Subsidiary of the Company in an involuntary case
      or proceeding under any Bankruptcy Law or to the commencement of any
      bankruptcy or insolvency case or proceeding against the Company or any
      Restricted Subsidiary of the Company, (iii) the filing by the Company or

      any Restricted Subsidiary of the Company of any plan or proposal for the
      liquidation or dissolution of the Company or any Restricted Subsidiary of
      the Company, or (viii) the taking of corporate action by the Company or
      any Restricted Subsidiary of the Company in furtherance of any such
      action.

The foregoing will constitute Events of Default whatever the reason for any such
Event of Default and whether it is voluntary or involuntary or is effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

            (b) The Company shall deliver to the Trustee upon becoming aware of
any Default or Event of Default written notice in the form of an Officers'
Certificate of any Default or Event of Default, their status and what action the
Company is taking or proposes to take in respect thereof.

            Section 6.2. Acceleration.


                                       59
<PAGE>

            (a) If an Event of Default (other than an Event of Default specified
in clauses (7) and (8) above with respect to the Company) shall occur and be
continuing, the Trustee or the Holders of at least 25% in principal amount of
outstanding Notes may declare the unpaid principal of and accrued and unpaid
interest on all the Notes to be immediately due and payable by notice in writing
to the Company and the Trustee specifying the Event of Default and that it is a
"notice of acceleration." If an Event of Default specified in clauses (7) and
(8) above occurs with respect to the Company, then the unpaid principal of and
accrued and unpaid interest on all the Notes will become immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

            (b) At any time after a declaration of acceleration with respect to
the Notes as described in the preceding paragraph, the Holders of a majority in
principal amount of such Notes may rescind and cancel such declaration and its
consequences:

            (1) if the rescission would not conflict with any judgment or
      decree;

            (2) if all existing Events of Default have been cured or waived,
      except nonpayment of principal or interest that has become due solely
      because of the acceleration;

            (3) to the extent the payment of such interest is lawful, interest
      on overdue installments of interest and overdue principal, which has
      become due otherwise than by such declaration of acceleration, has been
      paid; and

            (4) if the Company has paid the Trustee its reasonable compensation
      and reimbursed the Trustee for its reasonable expenses, disbursements and
      advances.

No recission shall affect any subsequent Default or impair any rights relating
thereto.

            Section 6.3. Other Remedies.

            (a) If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal of and interest
on the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

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

            Section 6.4. Waiver of Past Defaults. The Holders of a majority in
principal amount of the Notes may waive any existing Default or Event of
Default, and its consequences, except a default in the payment of the principal
of, premium, if any, or interest on such Notes.

            Section 6.5. Control by Majority. The Holders of a majority in
principal amount of the Outstanding Notes may direct the time, method and place
of conducting any proceeding


                                       60
<PAGE>

for any remedy available to the Trustee or of exercising any trust or power
conferred on the Trustee. Subject to Sections 7.1 and 7.2, however, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction.

            Section 6.6. Limitation on Suits. (a) Subject to the provisions of
this Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under this Indenture at the
request, order or direction of any of the Holders of the Notes unless such
Holders have offered to the Trustee reasonable security or indemnity. Subject to
all provisions of this Indenture and applicable law, the Holders of a majority
in aggregate principal amount of the then outstanding Notes 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.

            (b) No Holder of any Notes will have any right to institute any
proceeding with respect to this Indenture or for any remedy thereunder, unless:

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

            (2) Holders of at least 25% in principal amount of the then
      outstanding Dollar Notes or Euro Notes, as the case may be, make a written
      request to pursue the remedy;

            (3) such Holders of the Dollar Notes or Euro Notes, as the case may
      be, provide to the Trustee satisfactory indemnity;

            (4) the Trustee does not comply within 60 days; and

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

            Otherwise, no Holder of any Notes will have any right to institute
any proceeding with respect to this Indenture or for any remedy hereunder,
except:

            (1) a Holder of Notes may institute suit for enforcement of payment
of the principal of and premium, if any, or interest on such Note held by it on
or after the respective due dates expressed in such Note, or

            (2) for the institution of any proceeding with respect to this
Indenture or any remedy hereunder, including, without limitation, acceleration,
by the Holders of a majority in principal amount of the outstanding Notes;
provided, that upon institution of any proceeding or exercise of any remedy,
such Holder or Holders provide the Trustee with prompt notice thereof.

            Section 6.7. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture (including, without limitation, Section
6.6), the right of any Holder to receive payment of principal of or interest on
the Notes held by such Holder, on or after the respective due dates, Redemption
Dates or repurchase date expressed in this Indenture or the


                                       61
<PAGE>

Notes, or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

            Section 6.8. Collection Suit by Trustee. If an Event of Default
specified in Section 6.1 (1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with applicable
interest on any overdue principal and, to the extent lawful, interest on overdue
interest) and the amounts provided for in Section 7.7.

            Section 6.9. Trustee May File Proofs of Claim, etc.

            (a) The Trustee may (irrespective of whether the principal of the
Notes is then due):

            (i) file such proofs of claim and other papers or documents as may
      be necessary or advisable in order to have the claims of the Trustee and
      the Holders under this Indenture and the Notes allowed in any bankruptcy,
      insolvency, liquidation or other judicial proceedings relative to the
      Company or any Subsidiary of the Company or its or their respective
      creditors or properties; and

            (ii) collect and receive any monies or other property payable or
      deliverable in respect of any such claims and distribute them in
      accordance with this Indenture.

Any receiver, trustee, liquidator, sequestrator (or other similar official) in
any such proceeding is hereby authorized by each Holder to make such payments to
the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, taxes, disbursements and advances
of the Trustee, its agent and counsel, and any other amounts due to the Trustee
pursuant to Section 7.7.

            (b) Nothing in 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
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceeding.

            Section 6.10. Priorities. If the Trustee collects any money or
property pursuant to this Article VI, it shall pay out the money or property in
the following order:

            FIRST: to the Trustee for amounts due under Section 7.7;

            SECOND: if the Holders proceed against the Company directly without
      the Trustee in accordance with this Indenture, to Holders for their
      collection costs;

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


                                       62
<PAGE>

            FOURTH: to the Company or to such party as a court of competent
      jurisdiction shall direct.

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

            Section 6.11. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by the Company, a suit by a Holder pursuant to Section 6.7 or a
suit by Holders of more than 10% in principal amount of Outstanding Notes.

                                   ARTICLE VII

                                     TRUSTEE

            Section 7.1. Duties of Trustee.

            (a) If a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise 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.

            (b) Except during the continuance of a Default or 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 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.
      However, in the case of any such certificates or opinions which by any
      provisions hereof are specifically required to be furnished to the
      Trustee, the Trustee shall examine such certificates and opinions to
      determine whether or not they conform to the requirements of this
      Indenture (but need not confirm or investigate the accuracy of
      mathematical calculations or other facts stated therein).

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

            (1) this paragraph (c) does not limit the effect of paragraph (b) of
      this Section 7.1;


                                       63
<PAGE>

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

            (3) the Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.2, 6.4 or 6.5.

            (d) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

            (e) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

            (f) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur 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 to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

            (g) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Article VII and to the provisions of the TIA.

            (h) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

            (i) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

            Section 7.2. Rights of Trustee. Subject to Section 7.1:

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

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

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


                                       64
<PAGE>

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute
willful misconduct or negligence.

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

            (f) If the Trustee shall determine, it shall be entitled to examine
the books, records and premises of the Company, personally or by agent or
attorney.

            (g) The Trustee shall not be deemed to have notice of any Default or
Event of Default unless an 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 Notes and this Indenture.

            (h) The rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder.

            (i) The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

            Section 7.3. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or any of its Affiliates with the same
rights it would have if it were not Trustee. Any Paying Agent, Registrar or
co-Registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

            Section 7.4. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Company's use
of the proceeds from the Notes, and it shall not be responsible for any
statement of the Company in this Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Trustee's
certificate of authentication.

            Section 7.5. Notice of Defaults.

            If a Default or Event of Default occurs and is continuing and if a
Trust Officer has actual knowledge thereof, the Trustee shall mail to each
Holder notice of the Default or Event of Default within 90 days after the
occurrence thereof. Except in the case of a Default or Event of Default in
payment of principal of or interest on any Note (including payments pursuant to
the


                                       65
<PAGE>

optional redemption or required repurchase provisions of such Note, if any), the
Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of the Holders.

            Section 7.6. Reports by Trustee to Holders. The Trustee shall comply
with TIA ss. 313. The Company agrees to notify promptly the Trustee whenever the
Notes become listed on any stock exchange and of any delisting thereof.

            Section 7.7. Compensation and Indemnity.

            (a) The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the
Company and the Trustee shall from time to time agree in writing. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, costs of preparing and reviewing reports, certificates and other
documents, costs of preparation and mailing of notices to Holders and reasonable
costs of counsel retained by the Trustee in connection with the delivery of an
Opinion of Counsel or otherwise, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts.

            (b) The Company shall indemnify the Trustee against any and all
loss, liability or expense (including reasonable attorneys' fees and expenses)
incurred by it without gross negligence, willful misconduct or bad faith on its
part in connection with the acceptance and administration of this trust and the
performance of its duties hereunder, including the costs and expenses of
enforcing this Indenture (including this Section 7.7) and of defending itself
against any claims (whether asserted by any Holder, the Company or otherwise).
The Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company of its obligations hereunder. The Company shall defend the claim and the
Trustee may have separate counsel and the Company shall pay the fees and
expenses of such counsel provided that the Company shall not be required to pay
such fees and expenses if it assumes the Trustee's defense, and, in the
reasonable judgment of outside counsel to the Trustee, there is no conflict of
interest between the Company and the Trustee in connection with such defense.
The Company need not reimburse any expense or indemnify against any loss,
liability or expense incurred by the Trustee through the Trustee's own willful
misconduct, gross negligence or bad faith.

            (c) To secure the Company's payment obligations in this Section 7.7,
the Trustee shall have a lien prior to the Notes on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Notes. The Trustee's right to receive
payment of any amounts due under this Section 7.7 shall not be subordinate to
any other liability or Indebtedness of the Company.

            (d) The Company's payment obligations pursuant to this Section 7.7
shall survive the discharge of this Indenture and the resignation or removal of
the Trustee. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.1(7) or (8) , the expenses are intended to constitute
expenses of administration under any Bankruptcy Law; provided,


                                       66
<PAGE>

however, that this shall not affect the Trustee's rights as set forth in this
Section 7.7 or Section 6.10.

            Section 7.8. Replacement of Trustee.

            (a) The Trustee may resign at any time by so notifying the Company.
The Holders of a majority in principal amount of the Outstanding Notes may
remove the Trustee by so notifying the Trustee and may appoint a successor
Trustee reasonably acceptable to the Company. The Company shall remove the
Trustee if:

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee otherwise becomes incapable of acting.

            (b) If the Trustee resigns or is removed by the Company or by the
Holders of a majority in principal amount of the Outstanding Notes and such
Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy
exists in the office of the Trustee for any reason (the Trustee in such event
being referred to herein as the retiring Trustee), the Company shall promptly
appoint a successor Trustee.

            (c) A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject to the lien provided for
in Section 7.7.

            (d) If a successor Trustee does not take office within 30 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders
of 10% in principal amount of the Outstanding Notes may petition, at the
Company's expense, any court of competent jurisdiction for the appointment of a
successor Trustee.

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

            (f) Notwithstanding the replacement of the Trustee pursuant to this
Section 7.8, the Company's obligations under Section 7.7 shall continue for the
benefit of the retiring Trustee.

            Section 7.9. Successor Trustee by Merger.

            (a) If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all its corporate trust business or assets to,
another corporation or banking


                                       67
<PAGE>

association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

            (b) In case at the time such successor or successors to the Trustee
shall succeed to the trusts created by this Indenture, any of the Notes shall
have been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not
have been authenticated, any successor to the Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Notes or in this Indenture provided that
the certificate of the Trustee shall have.

            Section 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA ss. 310(a). The Trustee shall have a
combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

            Section 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

            Section 7.12. Appointment of Co-Trustee. (a) Notwithstanding any
other provisions in this Indenture, at any time, solely for the purpose of
meeting the legal requirements of any jurisdiction, the Trustee shall have the
power and may execute and deliver all instruments necessary to appoint one or
more Persons to act as separate trustee or trustees or as co-trustee or
co-trustees, and to vest in such Person or Persons, in such capacity and subject
to the other provisions of this Indenture, such powers, duties, obligations and
rights as the Trustee may consider necessary or desirable. No co-trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under this Indenture and no notice to holders of Notes of the
appointment of a separate trustee or co-trustee shall be required under this
Indenture.

            (b) Every separate trustee or co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

            (i) all rights, powers, duties and obligations conferred or imposed
      upon the Trustee shall be conferred or imposed upon and exercised or
      performed by the Trustee and such separate trustee or co-trustee jointly
      (it being understood that such separate trustee or co-trustee us not
      authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations shall be exercised and
      performed singly by such co-trustee, but solely at the direction of the
      Trustee;


                                       68
<PAGE>

            (ii) no trustee hereunder shall be personally liable by reason of
      any act or omission of any other trustee hereunder; and

            (iii) the Trustee may at any time accept the resignation of or
      remove any separate trustee or co-trustee.

            (c) Any notice, request or other writing given to the Trustee shall
      be deemed to have been given to each of the then separate trustees or
      co-trustees, as effectively as if given to each of them. Every instrument
      appointing any separate trustee or co-trustee shall refer to this
      Indenture and the conditions of this Article VII. Each separate trustee or
      co-trustee, upon its acceptance of the trusts conferred, shall be vested
      with the estates or property specified in its instrument of appointment,
      jointly with the Trustee, subject to all the provisions of this Indenture,
      specifically including every provision of this Indenture relating to the
      conduct of, affecting the liability of, or affording protection or rights
      (including the rights to compensation, reimbursement and indemnification
      hereunder) to, the Trustee. Every such instrument shall be filed with the
      Trustee.

            (d) Any separate trustee or co-trustee may at any time constitute
      the Trustee or its agent or attorney-in-fact with full power and
      authority, to the extent not prohibited by law, to do any lawful act under
      or in respect of this Indenture on its behalf and in its name. If any
      separate trustee or co-trustee shall die, become incapable of acting,
      resign or be removed, all of its estates, properties, rights, remedies and
      trusts shall vest in and be exercised by the Trustee, to the extent
      permitted by law, without the appointment of a new or successor trustee.

                                  ARTICLE VIII

                       DEFEASANCE; DISCHARGE OF INDENTURE

            Section 8.1. Legal Defeasance and Covenant Defeasance.

            (a) The Company may, at its option, at any time, elect to have
either paragraph (b) or (c) of this Section 8.1 be applied to all Outstanding
Notes upon compliance with the conditions set forth in Section 8.2.

            (b) Upon the Company's exercise under paragraph (a) of this Section
8.1 of the option applicable to this paragraph (b), the Company shall, subject
to the satisfaction of the conditions set forth in Section 8.2, be deemed to
have paid and been discharged from its obligations with respect to all
Outstanding Notes on the date all of the conditions set forth in Section 8.2
(including Section 8.2(4)(b)) are satisfied (hereinafter, "Legal Defeasance").
For this purpose, Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire Indebtedness represented by the Outstanding
Notes, which shall thereafter be deemed to be Outstanding only for the purposes
of Section 8.3 and the other Sections of this Indenture referred to in clause
(i) or (ii) of this paragraph (b), and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions, which shall
survive until otherwise terminated or discharged hereunder:


                                       69
<PAGE>

            (i) the rights of Holders of Outstanding Notes to receive solely
      from the trust fund described in Section 8.3, and as more fully set forth
      in Section 8.3, payments in respect of the principal of and interest on
      such Notes when such payments are due,

            (ii) the Company's obligations with respect to such Notes under
      Article II and Section 3.2,

            (iii) the rights, powers, trusts, duties and immunities of the
      Trustee hereunder and the Company's obligations in connection therewith,
      and

            (iv) this Article VIII.

Subject to compliance with this Article VIII, the Company may exercise its
option under this paragraph (b) notwithstanding the prior exercise of its option
under paragraph (c) of this Section 8.1.

            (c) Upon the Company's exercise under paragraph (a) of this Section
8.1 of the option applicable to this paragraph (c), the Company shall, subject
to the satisfaction of the applicable conditions set forth in Section 8.2, be
released from its obligations under the covenants contained in Sections 3.4,
3.5, 3.8 to 3.18 and 4.1 with respect to the Outstanding Notes on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"), and the Notes shall thereafter be deemed not Outstanding for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be Outstanding for all other purposes hereunder (it being understood
that such Notes shall not be deemed Outstanding for accounting purposes). For
this purpose, such Covenant Defeasance means that, with respect to the
Outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event or Default under Section
6.1(3) to (6), but, except as specified above, the remainder of this Indenture
and such Notes shall be unaffected thereby.

            Section 8.2. Conditions to Defeasance. The Company may exercise its
Legal Defeasance option or its Covenant Defeasance option only if:

            (1) the Company irrevocably deposits with the Trustee, in trust for
      the benefit of the Holders, U.S. Legal Tender, U.S. Government Obligations
      or a combination thereof in such amounts as will be sufficient without
      reinvestment, in the opinion of a nationally recognized firm of
      independent public accountants, to pay the principal of and interest on
      the Notes on the stated date for payment thereof or on the applicable
      redemption date, as the case may be, and the Trustee has a perfected first
      priority security interest under applicable law in such U.S. Legal Tender
      and U.S. Government Obligations;

            (2) in the case of Legal Defeasance, the Company shall have
      delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee to the effect that: (A) the Company
      has received from, or there has been published by, the

<PAGE>

      Internal Revenue Service a ruling or (B) since the Issue Date, there has
      been a change in the applicable federal income tax law, in either case to
      the effect that, and based thereon such Opinion of Counsel shall state
      that, the Holders will not recognize income, gain or loss for federal
      income tax purposes as a result of such Legal Defeasance and will be
      subject to federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such Legal Defeasance had
      not occurred;

            (3) in the case of Covenant Defeasance, the Company shall have
      delivered to the Trustee an Opinion of Counsel in the United States
      reasonably acceptable to the Trustee to the effect that the Holders will
      not recognize income, gain or loss for federal income tax purposes as a
      result of such Covenant Defeasance and will be subject to federal income
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if such Covenant Defeasance had not occurred;

            (4) the Trustee shall have received, on the date of the deposit
      pursuant to paragraph (1) above and on the 91st day after such date, an
      Officers' Certificate stating that (a) no Default or Event of Default
      shall have occurred and be continuing on the date of the deposit pursuant
      to paragraph (1) above (except any Default or Event of Default resulting
      from the failure to comply with Section 3.10 hereof as a result of the
      borrowing of the funds required to effect such deposit) and, (b) insofar
      as Events of Default from bankruptcy or insolvency events are concerned,
      no Default or Event of Default shall have occurred at any time in the
      period ending on the 91st day after the date of deposit and, in the case
      of Legal Defeasance, no such Default or Event of Default shall have
      occurred and be continuing on such 91st day;

            (5) the Trustee shall have received an Officers' Certificate stating
      that such Legal Defeasance or Covenant Defeasance shall not result in a
      breach or violation of, or constitute a default under this Indenture or
      any other material agreement or instrument to which the Company or any of
      its Restricted Subsidiaries is a party or by which the Company or any of
      its Subsidiaries is bound;

            (6) the Company shall have delivered to the Trustee an Officers'
      Certificate stating that the deposit was not made by the Company with the
      intent of preferring the Holders over any other creditors of the Company
      or any Subsidiary of the Company or with the intent of defeating,
      hindering, delaying or defrauding any other creditors of the Company or
      others;

            (7) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with;

            (8) the Company shall have delivered to the Trustee an Opinion of
      Counsel to the effect that after the 91st day following the deposit, the
      trust funds will not be subject to the effect of any applicable
      bankruptcy, insolvency, reorganization or similar laws affecting
      creditors' rights generally; and


                                       71
<PAGE>

            (9) the Company shall have delivered to the Trustee an Opinion of
      Counsel (subject to customary assumptions and exclusions) to the effect
      that the trust resulting from the deposit does not constitute, or is
      qualified as, a regulated investment company under the Investment Company
      Act of 1940.

            Section 8.3. Application of Trust Money. The Trustee shall hold in
trust U.S. Legal Tender or U.S. Government Obligations deposited with it

the Notes.

            Section 8.4. Repayment to Company.

            (a) The Trustee and the Paying Agent shall promptly turn over to the
Company upon request any excess money or securities held by them upon payment of
all the obligations under this Indenture.

            (b) Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal of or interest on the Notes that remains
unclaimed for two years, and, thereafter, Holders entitled to the money must
look to the Company for payment as general creditors.

            Section 8.5. Indemnity for U.S. Government Obligations The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

            Section 8.6. Reinstatement. If the Trustee or Paying Agent is unable
to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with
this Article VIII 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 Company under
this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S.
Government Obligations in accordance with this Article VIII; provided, however,
that, if the Company has made any payment of interest on or principal of any
Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the U.S. Legal Tender or U.S. Government Obligations held by the Trustee or
Paying Agent.

            Section 8.7. Satisfaction and Discharge. The Indenture will be
discharged and will cease to be of further effect (except as to surviving rights
or registration of transfer or exchange of the Notes, as expressly provided for

      and Notes for whose payment money has theretofor been deposited in trust
      or segregated and held in trust by the Company and thereafter repaid to
      the Company or discharged from such trust) have been delivered to the
      Trustee for cancellation; or

            (2) all Notes not theretofor delivered to the Trustee for
      cancellation have become due and payable, and the Company has irrevocably
      deposited or caused to be deposited with the Trustee U.S. Legal Tender or

      Indebtedness on the Notes not theretofor delivered to the Trustee for
      cancellation, for principal of and interest on the Notes to the date of
      deposit, together with irrevocable instructions from the Company directing
      the Trustee to apply such funds to the payment;

            (b) the Company has paid all other sums payable under this Indenture

                                   ARTICLE IX

                                   AMENDMENTS

            Section 9.1. Without Consent of Holders.

            (a) The Company and the Trustee may amend this Indenture or the
Notes without notice to or consent of any Holder:

            (1) to cure any ambiguity, omission, defect or inconsistency;

      Surviving Entity of the obligations of the Company under the Notes and
      this Indenture;

            (3) to provide for uncertificated Notes in addition to or in place
      of certificated Notes; provided, however, that the uncertificated Notes
      are issued in registered form for purposes of Section 163(f) of the Code;

            (4) to add guarantees with respect to the Notes or to secure the

<PAGE>

            (7) to make any change that does not, in the opinion of the Trustee,
      adversely affect the rights of any Holder in any material respect; or

            (8) to provide for the issuance of the Exchange Notes and Private
      Exchange Notes, which will have terms substantially identical to the other
      Outstanding Notes except for the requirement of a Private Placement Legend
      and related transfer restrictions under the Securities Act and this
      Indenture and as to the applicability of additional interest payable as
      provided in Section 2.14, and which will be treated, together with any
      other Outstanding Notes, as a single issue of securities.

            (b) After an amendment under this Section 9.1 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.1.

            Section 9.2. With Consent of Holders.

            (a) The Company and the Trustee may amend this Indenture or the
Notes without notice to any Holder but with the written consent of the Holders
of at least a majority in principal amount of the then Outstanding Notes
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes). However, without the consent
of each Holder affected, an amendment may not:

            (1) reduce the amount of Notes whose Holders must consent to an
      amendment or waiver;

            (2) reduce the rate of or change or have the effect of changing the
      time for payment of interest, including Defaulted Interest, on any Notes;

            (3) reduce the principal of or change or have the effect of changing
      the fixed maturity of any Notes, or change the date on which any Notes may
      be subject to redemption, or reduce the redemption price therefor;

            (4) make any Notes payable in money other than that stated in the
      Notes;

            (5) make any change in the provisions of this Indenture entitling
      each Holder to receive payment of principal of and interest on such Notes
      on or after the due date thereof or to bring suit to enforce such payment,
      or permitting Holders of a majority in principal amount of Outstanding
      Notes to waive Defaults or Events of Default;

            (6) amend, change or modify in any material respect any obligation
      of the Company to make and consummate a Change of Control Offer in respect
      of a Change of Control that has occurred or make and consummate an Asset
      Sale Offer with respect to any Asset Sale that has been consummated; or

            (7) amend, change or modify the seniority of the Notes or eliminate,
      release or modify any guarantee or security for the Notes except in
      accordance with the terms of the Notes or this Indenture.


                                       74
<PAGE>

            (b) It shall not be necessary for the consent of the Holders under
this Section 9.2 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent approves the substance thereof.

            (c) After an amendment under this Section 9.2 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.2.

            Section 9.3. Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Notes shall comply with the TIA as then in effect.

            Section 9.4. Revocation and Effect of Consents and Waivers.

            (a) A consent to an amendment or a waiver by a Holder of a Note
shall bind the Holder and every subsequent Holder of that Note or portion of the
Note that evidences the same debt as the consenting Holder's Note, even if
notation of the consent or waiver is not made on the Note. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Note or portion of the Note if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Holder. An amendment or waiver
shall become effective upon receipt by the Trustee of the requisite number of
written consents under Section 9.2.

            (b) The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall become valid or effective more than 90
days after such record date.

            Section 9.5. Notation on or Exchange of Notes. If an amendment
changes the terms of a Note, the Trustee may require the Holder of the Note to
deliver it to the Trustee. The Trustee may place an appropriate notation on the
Note regarding the changed terms and return it to the Holder. Alternatively, if
the Company or the Trustee so determines, the Company in exchange for the Note
will execute and upon Company Order the Trustee will authenticate a new Note
that reflects the changed terms. Failure to make the appropriate notation or to
issue a new Note shall not affect the validity of such amendment.

            Section 9.6. Trustee to Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in
relying upon, such evidence as it deems appropriate, including, without
limitation, solely on an Opinion of Counsel stating that such amendment is
authorized or permitted by this Indenture.

<PAGE>

            (1) an Officers' Certificate in form and substance reasonably
      satisfactory to the Trustee stating that, in the opinion of the signers,
      all conditions precedent, if any, provided for in this Indenture relating
      to the proposed action have been complied with; and

            (2) an Opinion of Counsel in form and substance reasonably
      satisfactory to the Trustee stating that, in the opinion of such counsel,
      all such conditions precedent have been complied with.

            Section 10.5. Statements Required in Certificate or Opinion. Each

            (1) a statement that the individual making such certificate or

      an informed opinion as to whether or not such covenant or condition has
      been complied with; and

            (4) a statement as to whether or not, in the opinion of such
      individual, such covenant or condition has been complied with.

In giving such Opinion of Counsel, counsel may rely as to factual matters on an
Officers' Certificate or on certificates of public officials.

            Section 10.6. Rules by Trustee, Paying Agent and Registrar. The
Trustee may make reasonable rules for action by, or a meeting of, Holders. The
Registrar and the Paying Agent may make reasonable rules for their functions.

            Section 10.7. Currency Indemnity.

            (a) U.S. Legal Tender is the sole currency of account and payment
for all sums payable by the Company under or in connection with the Notes or
this Indenture, including damages. Any amount received or recovered in currency
other than U.S. Legal Tender in respect of the Notes (whether as a result of, or
of the enforcement of, a judgment or order of a court of any jurisdiction, in
the winding-up or dissolution of the Company, any Subsidiary or otherwise) by
any Holder of the Notes in respect of any sum expressed to be due to it from the
Company or its Subsidiaries shall only constitute a discharge of the Company and
its Subsidiaries under the Notes and this Indenture only to the extent of the
U.S. Legal Tender 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 that U.S. Legal Tender
amount is less than the U.S. Legal Tender amount expressed to be due to the
recipient under the Notes or this Indenture, the


                                       77
<PAGE>

Company shall indemnify and hold harmless the recipient against any loss or cost
sustained by it in making any such purchase. For the purposes of this Section
10.7, it will be sufficient for the Holder of a Note to certify that it would
have suffered a loss had an actual purchase of U.S. Legal Tender been made with
the amount so received in that other currency on the date of receipt or recovery
(or, if a purchase of U.S. Legal Tender on such date had not been practicable,
on the first date on which it would have been practicable).

            (b) The indemnities of the Company contained in this Section 10.7,
to the extent permitted by law: (i) constitute a separate and independent
obligation from the other obligations of the Company under this Indenture and
the Notes; (ii) shall give rise to a separate and independent cause of action
against the Company; (iii) shall apply irrespective of any waiver granted by any
Holder of the Notes or the Trustee from time to time; and (iv) shall continue in
full force and effect notwithstanding any other judgment, order, claim or proof
of claim for a liquidated amount in respect of any sum due under the Notes or
this Indenture or any other judgment or order.

            Section 10.8. Legal Holidays. A "Legal Holiday" is a Saturday, a
Sunday or other day on which commercial banking institutions are authorized or
required to be closed in New York City. If a payment date is a Legal Holiday,
payment shall be made on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period. If a regular record
date is a Legal Holiday, the record date shall not be affected.

            Section 10.9. Governing Law, etc. THIS INDENTURE AND THE NOTES SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO
THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY. THE PARTIES HERETO EACH HEREBY WAIVE ANY RIGHT TO TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
THIS INDENTURE OR THE NOTES OR ANY TRANSACTION RELATED HERETO OR THERETO.

            Section 10.10. No Recourse Against Others. An incorporator,
director, officer, employee, stockholder or controlling person, as such, of the
Company shall not have any liability for any obligations of the Company under
the Notes, this Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. By accepting a Note, each Holder shall
waive and release all such liability. The waiver and release shall be part of
the consideration for the issue of the Notes.

            Section 10.11. Successors. All agreements of the Company in this
Indenture and the Notes shall bind its successors. All agreements of the Trustee
in this Indenture shall bind its successors.

            Section 10.12. Duplicate and Counterpart Originals. The parties may
sign any number of copies of this Indenture. One signed copy is enough to prove
this Indenture. This Indenture may be executed in any number of counterparts,
each of which so executed shall be an original, but all of them together
represent the same agreement.

            Section 10.13. Severability. In case any provision in this Indenture
or in the Notes 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 10.14. Qualification of Indenture. The Company shall qualify
this Indenture under the TIA in accordance with the terms and conditions of the
Registration Agreement and shall pay all reasonable costs and expenses
(including attorneys' fees and expenses for the Company, the Trustee and the
Holders) incurred in connection therewith, including, but not limited to, costs
and expenses of qualification of this Indenture and the Notes and printing this
Indenture and the Notes. The Trustee shall be entitled to receive from the
Company any such Officers' Certificates, Opinions of Counsel or other
documentation as it may reasonably request in connection with any such
qualification of this Indenture under the TIA.

            Section 10.15. Table of Contents; Headings. The table of contents
and headings of the Articles and Sections of this Indenture have been inserted
for convenience of reference only, are not intended to be considered a part
hereof and shall not modify or restrict any of the terms or provisions hereof.

            Section 10.16. Agent for Service; Submission to Jurisdiction; Waiver
of Immunities.

            The Company agrees that any suit, action or proceeding against the
Company brought by any Holder or the Trustee arising out of or based upon this
Indenture or the Notes may be instituted in any state or federal court in the
Borough of Manhattan, The City of New York, New York, United States, any court
of competent jurisdiction in Bermuda or England and Wales and any appellate
court from any thereof. The Company hereby irrevocably submits to the
non-exclusive jurisdiction of such courts for such purpose and waives, to the
fullest extent permitted by law, trial by jury and any objection it may now or
hereafter have to the laying of venue of any such proceeding, and any claim it
may now or hereafter have that any proceeding in any such court is brought in an
inconvenient forum. The Company has appointed FLAG Telecom Holdings Ltd., 570
Lexington Avenue, New York, New York 10020 as its authorized agent (the
"Authorized Agent") upon whom all writs, process and summonses may be served in
any suit, action or proceeding arising out of or based upon this Indenture or
the Notes which may be instituted in any state or federal court in the Borough
of Manhattan, The City of New York, New York. The Company hereby represents and
warrants that the Authorized Agent has accepted such appointment and has agreed
to act as said agent for service of process, and the Company agrees to take any
and all action, including the filing of any and all documents, that may be
necessary to continue each such appointment in full force and effect as
aforesaid so long as the Notes remain outstanding. The Company agrees that the
appointment of the Authorized Agent shall be irrevocable so long as any of the
Notes remain outstanding or until the irrevocable appointment by the Company of
a successor agent in The City of New York, New York as its authorized agent for
such purpose and the acceptance of such appointment by such successor. Service
of process upon the Authorized Agent shall be deemed, in every respect,
effective service of process upon the Company.

            To the extent that the Company has or hereafter may acquire any
immunity (sovereign or otherwise) from any legal action, suit or proceeding,
from jurisdiction of any court


                                       79
<PAGE>

or from set-off or any legal process (whether service or notice, attachment in
aid or otherwise) with respect to itself or any of its property, the Company
hereby irrevocably waives and agrees not to plead or claim such immunity in
respect of its obligations under this Indenture or the Notes.

Nothing in this Section 10.16 shall affect the right of the Trustee or any
Holder of the Notes to serve process in any other manner permitted by law.


                                       80

                          FORM OF REVERSE SIDE OF NOTE

                      11.625% Senior Dollar Notes Due 2010

1. Interest

            FLAG Telecom Holdings Limited, a Bermuda corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown above.

            The Company will pay interest semiannually in arrears on each
Interest Payment Date of each year commencing September 30, 2000. Interest on
the Notes will accrue from the most recent date to which interest has been paid
on the Notes or, if no interest has been paid, from the Issue Date. The Company
shall pay interest on overdue principal (plus interest on such interest to the
extent lawful), at the rate borne by the Notes to the extent lawful. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

            The Company shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal and, to the extent
such payments are lawful, interest on overdue installments of interest
("Defaulted Interest") without regard to any applicable grace periods at the
rate of 2.0% per annum in excess of the rate shown on this Note, as provided in
the Indenture.

            All payments made by the Company in respect of the Notes will be
made free and clear of and without deduction or withholding for or on account of
any Taxes imposed or levied by or on behalf of any Taxing Authority, unless such
withholding or deduction is required by law or by the interpretation or
administration thereof. In that event, the Company will pay to each Holder of
the Notes Additional Amounts as provided in the Indenture subject to the
limitations set forth in the Indenture.

2. Method of Payment

            By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Note is due and payable, the Company shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal and/or interest. The Company will pay interest (except Defaulted
Interest) to the Persons who are registered Holders of Notes at the close of
business on the Record Date preceding the Interest Payment Date even if Notes
are canceled, repurchased or redeemed after the Record Date and on or before the
relevant Interest Payment Date. Holders must surrender Notes to a Paying Agent
to collect principal payments. The Company will pay principal and interest in
U.S. Legal Tender.

            Payments in respect of Notes represented by a Global Note (including
principal and interest) will be made by the transfer of immediately available
funds to the accounts specified by DTC. The Company will make all payments in
respect of a Certificated Note (including principal and interest) by mailing a
check to the registered address of each Holder


                                      A-5
<PAGE>

thereof; provided, however, that payments on the Notes may also be made, in the
case of a Holder of at least $1,000,000 aggregate principal amount of Notes, by
wire transfer to a U.S. dollar account maintained by the payee with a bank in
the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or the Paying Agent to such effect designating
such account no later than 15 days immediately preceding the relevant due date
for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar

            Initially, The Bank of New York (the "Trustee"), will act as
Trustee, Paying Agent and Registrar. The Company may appoint and change any
Paying Agent, Registrar or co-registrar without prior notice to any Holder. The
Company may act as Paying Agent, Registrar or co-registrar.

4. Indenture

            The Company issued the Notes under an Indenture, dated as of March
17, 2000 (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the "Indenture"), between the Company and the Trustee.
The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture. The Notes are subject to all such terms, and Holders
are referred to the Indenture and the Act for a statement of those terms. Each
Holder by accepting a Note, agrees to be bound by all of the terms and
provisions of the Indenture, as amended from time to time.

            The Notes are senior unsecured obligations of the Company, ranking
pari passu in right of payment with each other, the Euro Notes and with all
senior unsecured Indebtedness of the Company and senior in right of payment to
all Subordinated Indebtedness. The Notes are limited to $300 million aggregate
principal amount.

            The Indenture imposes certain limitations on, among other things,
the ability of the Company and its Restricted Subsidiaries to: incur
Indebtedness, make Restricted Payments, incur Liens, issue or sell Capital
Interests of Restricted Subsidiaries, consummate Asset Sales, enter into
transactions with Affiliates, or consolidate or merge or transfer or convey all
or substantially all of the Company's and its Restricted Subsidiaries' assets.

5. Redemption

            Optional Redemption. Except as stated below, the Company may not
redeem the Notes prior to March 30, 2005. The Company may redeem the Notes, at
its option, in whole at any time or in part from time to time, on and after
March 30, 2005, at the following redemption prices, expressed as percentages of
the principal amount thereof, plus accrued and unpaid interest to the date of
redemption, if redeemed during the twelve-month period commencing on March 30 of
any year set forth below:


                                      A-6
<PAGE>

       YEAR                                                    PERCENTAGE

            Optional Redemption Upon Public Equity Offerings. At any time, or
from time to time, on or prior to March 30, 2003 the Company may, at its option,
use the net cash proceeds of one or more Public Equity Offerings to redeem in
the aggregate up to 35% of the aggregate principal amount of the Notes
originally issued at a redemption price equal to 111.625% of the principal
amount thereof, plus accrued and unpaid interest thereon to the date of
redemption, provided, that:

            (1) after giving effect to any such redemption at least 65% of the
      aggregate principal amount of the Notes, originally issued remains
      outstanding; and

            (2) the Company shall make such redemption not more than 90 days
      after the consummation of such Public Equity Offering.

            Optional Tax Redemption. The Notes will be subject to redemption at
the option of the Company or a successor corporation at any time, in whole but
not in part, upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to the principal amount thereof plus accrued and unpaid
interest to the redemption date if, as a result of any change in or amendment to
the laws or any regulations or rulings promulgated thereunder of:

            (1) Bermuda or any political subdivision or governmental authority
      thereof or therein having power to tax,

            (2) any jurisdiction, other than the United States, the United
      Kingdom or Luxembourg, from or through which payment on the Notes is made
      by the Company or a successor corporation, or its paying agent in its
      capacity as such, or any political subdivision or governmental authority
      thereof or therein having the power to tax, or

            (3) any other jurisdiction, other than the United States, in which
      the Company or a successor corporation is organized, or any political
      subdivision or governmental authority thereof or therein having the power
      to tax, or any Change in Tax Law, which becomes effective on or after the
      date of the Offering Memorandum, the Company or a successor corporation is
      or would be required on the next succeeding Interest Payment Date to pay
      Additional Amounts with respect to the Notes, and the payment of such
      Additional Amounts cannot be avoided by the use of any reasonable measures
      available to the Company or the successor corporation.

            In the case of any partial redemption, selection of the Notes for
redemption will be made in accordance with Article V of the Indenture. On and
after the redemption date, interest will cease to accrue on Notes or portions
thereof called for redemption as long as the Company has deposited with the
Paying Agent funds in satisfaction of the applicable redemption price pursuant
to the Indenture.

6. Repurchase Provisions

            Change Of Control Offer. Upon the occurrence of a Change of Control,
each Holder of Notes will have the right to require that the Company purchase
all or a portion (in integral multiples of $1,000) of the Holder's Notes at a
purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest through the date of purchase. Within 30 days following the date
upon which the Change of Control occurred, the Company must send, by first-class
mail, a notice to each Holder of Notes, with a copy to the Trustee, offering to
purchase such Notes as described in the preceding sentence (a "Change of Control
Offer"). The Change of Control Offer shall state, among other things, the
purchase date, which must be no earlier than 30 days nor later than 60 days from
the date the notice is mailed, other than as may be required by law (the "Change
of Control Payment Date").

            Asset Sale Offer. The Indenture imposes certain limitations on the
ability of the Company and its Restricted Subsidiaries to sell assets. In the
event the proceeds from a permitted Asset Sale exceed certain amounts, as
specified in the Indenture, the Company generally will be required either to
reinvest the proceeds of such Asset Sale in a Permitted Business, use such
proceeds to retire debt, or to make an Asset Sale Offer to purchase a certain
amount of each Holder's Notes at 100% of the principal amount thereof, plus
accrued interest (if any) to the Asset Sale Offer Payment Date, as more fully
set forth in the Indenture.

7. Denominations; Transfer; Exchange

            The Notes are in fully registered form without coupons, and only in
denominations of principal amount of $1,000 and any integral multiple thereof. A
Holder may transfer or exchange Notes in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Notes selected for redemption (except, in the case of a Note
to be redeemed in part, the portion of the Note not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Notes to be redeemed and
ending on the date of such mailing or (ii) any Notes for a period beginning 15
days before an interest payment date and ending on such interest payment date.

8. Persons Deemed Owners

            The registered holder of this Note may be treated as the owner of it
for all purposes.

9. Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.


                                      A-8
<PAGE>

10. Discharge Prior to Redemption or Maturity

            Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of its obligations under the Notes
and the Indenture if the Company deposits with the Trustee U.S. Legal Tender or
U.S. Government Obligations for the payment of principal of and interest on the
Notes to redemption or maturity, as the case may be.

11. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Notes may be amended with the written consent of the Holders of
at least a majority in principal amount of the then Outstanding Notes and (ii)
any default (other than with respect to nonpayment or in respect of a provision
that cannot be amended without the written consent of each Holder affected) or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in principal amount of the then Outstanding Notes. Subject
to certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Notes to,
among other things, cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated Notes
in addition to or in place of certificated Notes, or to add guarantees with
respect to the Notes or to secure the Notes, or to add additional covenants or
surrender rights and powers conferred on the Company, or to comply with any
request of the SEC in connection with qualifying the Indenture under the Act, or
to make any change that does not adversely affect the rights of any Holder, or
to provide for the issuance of Exchange Notes.

12. Defaults and Remedies

            If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Notes may declare all the
Notes to be due and payable immediately. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Notes being due and
payable immediately upon the occurrence of such Events of Default.

            Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Notes unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the
Outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing Default or Event
of Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

13. Trustee Dealings with the Company

            Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Notes and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.


                                      A-9
<PAGE>

14. No Recourse Against Others

            An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of or by reason of such obligations or their creation. By
accepting a Note, each Holder waives and releases all such liability. The waiver
and release are part of the consideration for the issue of the Notes.

15. Authentication

            This Note shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Note.

entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

17. CUSIP Numbers

            Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Notes and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders. No representation is made as
to the accuracy of such numbers either as printed on the Notes or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

redemption and reliance may be placed only on the other identification numbers
placed thereon.]

18. Governing Law

            This Note shall be governed by, and construed in accordance with,
the laws of the State of New York, but without giving effect to applicable
principles of conflicts of law to the extent that the application of the law of
another jurisdiction would be required thereby.


                                      A-10

19. Currency of Account; Conversion of Currency.

            U.S. Legal Tender is the sole currency of account and payment for
all sums payable by the Company under or in connection with the Notes or the
Indenture, including damages. The Company will indemnify the Holders pursuant to
Section 10.7 of the Indenture in respect of the conversion of currency relating
to the Notes and the Indenture.

20. Agent for Service; Submission to Jurisdiction; Waiver of Immunities.

            The Company has agreed that any suit, action or proceeding against
the Company brought by any Holder or the Trustee arising out of or based upon
the Indenture or the Notes may be instituted in any state or federal court in
the Borough of Manhattan, The City of New York, New York, United States, and any
appellate court from any thereof. The Company has irrevocably submitted to the
non-exclusive jurisdiction of such courts for such purpose and waived, to the
fullest extent permitted by law, trial by jury and any objection it may now or
hereafter have to the laying of venue of any such proceeding, and any claim it
may now or hereafter have that any proceeding in any such court is brought in an
inconvenient forum. The Company has appointed FLAG Telecom Holdings Ltd. as its
authorized agent upon whom all writs, process and summonses may be served in any
suit, action or proceeding arising out of or based upon the Indenture or the
Notes which may be instituted in any state or federal court in the Borough of
Manhattan, The City of New York, New York. To the extent that the Company has or
hereafter may acquire any immunity (sovereign or otherwise) from any legal
action, suit or proceeding, from jurisdiction of any court or from set-off or
any legal process (whether service or notice, attachment in aid or otherwise)
with respect to itself or any of its property, the Company has irrevocably
waived and agreed not to plead or claim such immunity in respect of its
obligations under the Indenture or the Notes.

            The Company will furnish to any Holder upon written request and
without charge to the Holder a copy of the Indenture which has in it the text of
this Note in larger type. Requests may be made to:

                  Dollar Notes Due 2010 (the "Notes")

Ladies and Gentlemen:

governing the Exchange Notes and Private Exchange Notes.

            Underwritten registration or underwritten offering: A registration
in which securities of the Issuer are sold to an underwriter for reoffering to
the public.

            2. Exchange Offer.

            (a) The Issuer shall (A) prepare and, on or prior to 60 days after
the Issue Date (the "Exchange Filing Date"), file with the SEC a Registration
Statement under the Securities Act with respect to an offer by the Company to
the holders of the Notes to issue and deliver to such holders, in exchange for
Notes, a like principal amount of Exchange Notes (the "Exchange Offer"), (B) use
its best efforts to cause the Registration Statement relating to the Exchange
Offer to be declared effective by the SEC under the Securities Act on or prior
to 150 days after the Issue Date (the "Exchange Effectiveness Date") and (C)
commence the Exchange Offer and use its best efforts to issue, on or prior to
180 days after the Issue Date, the Exchange Notes. The offer and sale of the
Exchange Notes pursuant to the Exchange Offer shall be registered pursuant to
the Securities Act on the appropriate form (the "Exchange Registration
Statement") and duly registered or qualified under all applicable state
securities or Blue Sky laws and will comply with all applicable tender offer
rules and regulations under the Exchange Act and state securities or Blue Sky
laws. The Exchange Offer shall not be subject to any condition, other than that
the Exchange Offer does not violate any applicable law or interpretation of the
staff of the SEC. Upon consummation of the Exchange Offer in accordance with
this Section 2, the Issuer shall have no further registration obligations other
than with respect to (i) Private Exchange Notes, (ii) Exchange Notes held by
Participating Broker-Dealers and (iii) Notes or Exchange Notes as to which
Section 3 hereof applies. No securities shall be included in the Exchange
Registration Statement other than the Exchange Notes.

            (b) The Issuer may require each holder of Notes as a condition to
its participation in the Exchange Offer to represent to the Issuer and its
counsel in writing (which may be contained in the applicable letter of
transmittal) that at the time of the consummation of the Exchange Offer (i) any
Exchange Notes received by such holder will be acquired in the ordinary course
of its business, (ii) such holder will have no arrangement or understanding with
any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes and (iii) such holder is not an Affiliate
of the Issuer, or if it is an Affiliate of the Issuer, it will comply with the
registration and prospectus delivery requirements of the Securities Act, to the
extent applicable.

            If, prior to consummation of the Exchange Offer, an Initial
Purchaser holds any Notes acquired by it and having, or that are reasonably
likely to be determined to have, the status of an unsold allotment in the
initial distribution, or any other holder of Notes is not entitled to
participate in the Exchange Offer, the Company upon the request of such Initial
Purchaser or any such holder shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to such Initial


                                       5
<PAGE>

Purchaser and any such holder, in exchange (the "Private Exchange") for such
Notes held by such Initial Purchaser and any such holder, a like principal
amount of debt securities of the Company, that are identical in all material
respects to the Exchange Notes (the "Private Exchange Notes") (and that are
issued pursuant to the same indenture as the Exchange Notes). The Private
Exchange Notes shall bear the same CUSIP number as the Exchange Notes.

            The Issuer and the Initial Purchasers acknowledge that the staff of
the SEC has taken the position that any broker-dealer that owns Exchange Notes
that were received by such broker-dealer for its own account in the Exchange
Offer (a "Participating Broker-Dealer") may be deemed to be an "underwriter"
within the meaning of the Securities Act and must deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such
Exchange Notes (other than a resale of an unsold allotment resulting from the
original offering of the Notes).

            The Issuer and the Initial Purchasers also acknowledge that it is
the SEC staff's position that if the Prospectus contained in the Exchange
Registration Statement includes a plan of distribution containing a statement to
the above effect and the means by which Participating Broker-Dealers may resell
the Exchange Notes, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Notes owned by them, such Prospectus may be
delivered by Participating Broker-Dealers to satisfy their prospectus delivery
obligations under the Securities Act in connection with resales of Exchange
Notes for their own accounts, so long as the Prospectus otherwise meets the
requirements of the Securities Act.

            In light of the foregoing, if requested by a Participating
Broker-Dealer, the Issuer agrees (x) to use its best efforts to keep the
Exchange Registration Statement continuously effective for a period of up to six
months or such earlier date as each Participating Broker-Dealer shall have
notified the Company in writing that such Participating Broker-Dealer has resold
all Exchange Notes acquired in the Exchange Offer, (y) to comply with the
provisions of Section 5 of this Agreement, as they relate to the Exchange Offer
and the Exchange Registration Statement, and (z) to deliver to such
Participating Broker-Dealer a "cold comfort" letter of the independent public
accountants of the Issuer and a legal opinion as to matters reasonably requested
by such Participating Broker-Dealer relating to the Exchange Registration
Statement and the related Prospectus and any amendments or supplements thereto.

            Interest on the Exchange Notes and the Private Exchange Notes will
accrue from (A) the later of (i) the last interest payment date on which
interest was paid on the Notes surrendered in exchange therefor and (ii) if the
Notes are surrendered for exchange on a date in a period which includes the
record date for an interest payment date to occur on or after the


                                       6
<PAGE>

date of such exchange and as to which interest will be paid, the date of such
interest payment date or (B), if no interest has been paid on the Notes, from
the Issue Date.

In connection with each Exchange Offer, the Issuer shall:

            (1) mail, or cause to be mailed, to each Holder of record entitled
      to participate in the Exchange a copy of the Prospectus forming part of
      the Exchange Registration Statement, together with an appropriate letter
      of transmittal and related documents;

            (2) use their best efforts to keep the Exchange Offer open for not
      less than 20 business days after the date that notice of the Exchange
      Offer is mailed to Holders (or longer if required by applicable law);

            (3) utilize the services of a depositary for the Exchange Offer with
      an address in the Borough of Manhattan, The City of New York;

            (4) permit Holders to withdraw validly tendered Notes at any time
      prior to the close of business, New York time, on the last business day on
      which the Exchange Offer shall remain open; and

            (5) otherwise comply in all material respects with all applicable
      laws, rules and regulations.

            As soon as practicable after the close of the applicable Exchange
Offer and the applicable Private Exchange, if any, the Issuer shall:

            (1) accept for exchange all Registrable Notes validly tendered and
      not validly withdrawn pursuant to the applicable Exchange Offer and the
      applicable Private Exchange, if any;

            (2) deliver to the Trustee for cancellation all Registrable Notes so
      accepted for exchange and cause the Trustee to authenticate and deliver
      promptly to each Holder of Registrable Notes, Exchange Notes or Private
      Exchange Notes, as the case may be, equal in principal amount to the
      securities of such Holder so accepted for exchange.

            The Exchange Notes and the Private Exchange Notes shall be issued
under (i) the Indenture or (ii) an indenture identical in all material respects
to the Indenture and that, in either case, has been qualified under the TIA or
is exempt from such qualification and shall provide that (a) the Exchange Notes
shall not be subject to the transfer restrictions


                                       7
<PAGE>

set forth in the Indenture and (b) the Private Exchange Notes shall be subject
to the transfer restrictions set forth in such indenture. The Indenture or such
indenture shall provide that the Exchange Notes, the Private Exchange Notes and
the Notes shall vote and consent together on all matters as one class and that
none of the Exchange Notes, the Private Exchange Notes or the Notes will have
the right to vote or consent as a separate class on any matter.

            (c) If, (i) because of any change in law or in currently prevailing
interpretations of the staff of the SEC, the Issuer is not permitted to effect
the Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days
of the Issue Date, (iii) any holder of any Private Exchange Notes so requests in
writing to the Issuer within 45 days after the consummation of the Exchange
Offer, or (iv) in the case of any Holder that participates in the Exchange
Offer, such Holder does not receive Exchange Notes on the date of the exchange
that may be sold without restriction under state and federal securities laws
(other than due solely to the status of such Holder as an affiliate of the
Issuer within the meaning of the Securities Act), then in the case of each of
clauses (i) to and including (iv) of this sentence, the Issuer shall promptly
deliver to the Holders and the Trustee written notice thereof (the "Shelf
Notice") and shall file a Shelf Registration pursuant to Section 3 hereof.

            3. Shelf Registration.

            If at any time a Shelf Notice is delivered as contemplated by
Section 2(c) hereof, then:

            (a) Shelf Registration. The Issuer shall file with the SEC a
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange
Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is
applicable (the "Initial Shelf Registration"). The Issuer shall use its best
efforts to file with the SEC the Initial Shelf Registration on or before the
60th day after the occurrence of any of the events set forth in Section 2(c)
(the "Initial Shelf Registration Filing Date"). The Initial Shelf Registration
shall be on Form F-1 or another appropriate form permitting registration of such
Registrable Notes for resale by Holders in the manner or manners designated by
them (including, without limitation, one or more underwritten offerings). The
Issuer shall not permit any securities other than the Registrable Notes to be
included in the Initial Shelf Registration or any Subsequent Shelf Registration
(as defined below).

            The Issuer shall use its best efforts to cause the Initial Shelf
Registration to be declared effective under the Securities Act on or prior to
the 90th day after the Initial Shelf Registration Filing Date (the "Initial
Shelf Registration Effectiveness Date") and to keep the Initial Shelf
Registration continuously effective under the Securities Act until the date
which is the earlier of (a) two years from the Issue Date (the "Effectiveness
Period") and (b) such shorter period ending when (i) all Registrable Notes
covered by the Initial Shelf Registration have been sold in the manner set forth
and as contemplated in the Initial Shelf Registration or


                                       8
<PAGE>

(ii) a Subsequent Shelf Registration covering all of the Registrable Notes
covered by and not sold under the Initial Shelf Registration or an earlier
Subsequent Shelf Registration has been declared effective under the Securities
Act (the "Applicable Period"); provided, however, that the Effectiveness Period
in respect of the Initial Shelf Registration shall be extended to the extent
required to permit dealers to comply with the applicable prospectus delivery
requirements of Rule 174 under the Securities Act and as otherwise provided
herein.

            (b) Subsequent Shelf Registrations. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Issuer shall use its
best efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 30 days of such cessation
of effectiveness amend the Initial Shelf Registration in a manner to obtain the
withdrawal of the order suspending the effectiveness thereof, or file an
additional "shelf" Registration Statement pursuant to Rule 415 covering all of
the Registrable Notes covered by and not sold under the Initial Shelf
Registration or an earlier Subsequent Shelf Registration (each, a "Subsequent
Shelf Registration"). If a Subsequent Shelf Registration is filed, the Issuer
shall use its best efforts to cause the Subsequent Shelf Registration to be
declared effective under the Securities Act as soon as practicable after such
filing and to keep such subsequent Shelf Registration continuously effective for
the remainder of the Effectiveness Period. As used herein the term "Shelf
Registration" means the Initial Shelf Registration and any Subsequent Shelf
Registration.

            (c) Supplements and Amendments. The Issuer shall promptly supplement
and amend any Shelf Registration if required by the rules, regulations or
instructions applicable to the registration form used for such Shelf
Registration, if required by the Securities Act, or if reasonably requested by
the Holders of a majority in aggregate principal amount of the Registrable Notes
covered by such Registration Statement or by any underwriter of such Registrable
Notes.

            4. Additional Interest.

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

      (i) if (A) neither the Exchange Registration Statement nor the Initial
      Shelf Registration has been filed on or prior to the applicable Filing
      Date or (B) notwithstanding that the Issuer has consummated or will
      consummate the


                                       9
<PAGE>

      Exchange Offer, the Issuer is required to file a Shelf Registration and
      such Shelf Registration is not filed on or prior to the Filing Date
      applicable thereto, then commencing on the day after any such Filing Date,
      Additional Interest shall accrue on the principal amount of the Notes at a
      rate of 0.25% per annum for the first 30 days immediately following each
      such Filing Date, and such Additional Interest shall increase by an
      additional 0.25% per annum at the beginning of each subsequent 30-day
      period; or

      (ii) if (A) neither the Exchange Registration Statement nor the Initial
      Shelf Registration is declared effective by the SEC on or prior to the
      relevant Effectiveness Date or (B) notwithstanding that the Issuer has
      consummated or will consummate the Exchange Offer, the Issuer is required
      to file a Shelf Registration and such Shelf Registration is not declared
      effective by the SEC on or prior to the Effectiveness Date in respect of
      such Shelf Registration, then, commencing on the day after the applicable
      Effectiveness Date, Additional Interest shall accrue on the principal
      amount of the Notes at a rate of 0.25% per annum for the first 30 days
      immediately following the day after such Effectiveness Date, and the rate
      of such Additional Interest shall increase by an additional 0.25% per
      annum at the beginning of each subsequent 30-day period; or

      (iii) if (A) the Issuer has not exchanged Exchange Notes for all Notes
      validly tendered in accordance with the terms of the Exchange Offer on or
      prior to the 180th day after the Issue Date or (B) if applicable, a Shelf
      Registration has been declared effective and such Shelf Registration
      ceases to be effective at any time during the Effectiveness Period (other
      than such time as all Notes have been disposed of thereunder), then
      Additional Interest shall accrue on the principal amount of the Notes at a
      rate of 0.25% per annum for the first 30 days commencing on the (x) 181st
      day after such Issue Date, in the case of (A) above, or (y) the day such
      Shelf Registration ceases to be effective in the case of (B) above, such
      Additional Interest shall increase by an additional 0.25% per annum at the
      beginning of each such subsequent 30-day period (it being understood and
      agreed that, notwithstanding any provision to the contrary, so long as any
      Note that is the subject of a Shelf Notice is then covered by an effective
      Shelf Registration, no Additional Interest shall accrue or accumulate on
      such Notes);

provided, however, that the rate of Additional Interest that shall accrue on the
Notes may not exceed in the aggregate 1.50% per annum; provided, further,
however, that (1) upon the filing of the applicable Exchange Registration
Statement or the applicable Shelf Registration as required hereunder (in the
case of clause (i) above of this Section 4(a)), (2) upon the effectiveness of
the applicable Exchange Registration Statement or the applicable Shelf
Registration Statement as required hereunder (in the case of clause (ii) of this
Section 4(a)), or (3) upon the exchange of the applicable Exchange Notes for all
Notes tendered (in the case of


                                       10
<PAGE>

clause (iii)(A) of this Section 4(a), or upon the effectiveness of the
applicable Shelf Registration Statement which had ceased to remain effective (in
the case of (iii)(B) of this Section 4(a)), Additional Interest on the Notes in
respect of which such events relate as a result of such clause (or the relevant
subclause thereof), as the case may be, shall cease to accrue or accumulate, as
the case may be.

            (b) The Issuer shall notify the Trustee (who shall be acting under
and protected by the terms of the Indenture) within three business days after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date"). Any amounts of Additional
Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 shall be
payable in cash semiannually on each March 30 and September 30 (to the holders
of record on the March 15 and September 15 immediately preceding such dates),
commencing with the first such date occurring after any such Additional Interest
commences to accrue. The amount of Additional Interest will be determined by
multiplying the applicable rate of Additional Interest by the principal amount
of the Registrable Notes, multiplied by a fraction, the numerator of which is
the number of days such rate of Additional Interest was applicable during such
period (determined on the basis of a 360-day year comprised of twelve 30-day
months and, in the case of a partial month, the actual number of days elapsed),
and the denominator of which is 360.

            5. Registration Procedures.

            In connection with the filing of any Registration Statement pursuant
to Sections 2 or 3 hereof, the Issuer shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuer hereunder, the Issuer shall:

            (a) Prepare and file with the SEC prior to the applicable Filing
Date, a Registration Statement or Registration Statements as prescribed by
Sections 2 or 3 hereof, and use its best efforts to cause each such Registration
Statement to become effective and remain effective as provided herein; provided,
however, that, if (1) such filing is pursuant to Section 3 hereof, or (2) a
Prospectus contained in the Exchange Registration Statement filed pursuant to
Section 2 hereof is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period relating thereto, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, the Issuer shall furnish to
and afford the Holders of the Registrable Notes included in such Registration
Statement or each such Participating Broker-Dealer, as the case may be, their
counsel and the managing underwriters, if any, a reasonable opportunity to
review copies of all such documents (including copies of any documents to be
incorporated by reference therein and all exhibits thereto) proposed to be filed
(in each case at least five days prior to such filing, or such later date as is
reasonable under the


                                       11
<PAGE>

circumstances). The Issuer shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in aggregate principal amount of the Registrable Notes included in such
Registration Statement, or any such Participating Broker-Dealer, as the case may
be, their counsel, or the managing underwriters, if any, shall reasonably object
in writing on a timely basis.

            (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration Statement or Exchange Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented by
any prospectus supplement required by applicable law, and as so supplemented to
be filed pursuant to Rule 424 (or any similar provisions then in force)
promulgated under the Securities Act; and comply with the provisions of the
Securities Act and the Exchange Act applicable to it with respect to the
disposition of all securities covered by such Registration Statement as so
amended or in such Prospectus as so supplemented and with respect to the
subsequent resale of any securities being sold by a Participating Broker-Dealer
covered by any such Prospectus. The Issuer shall be deemed not to have used its
best efforts to keep a Registration Statement effective during the Effectiveness
Period or the Applicable Period, as the case may be, relating thereto if the
Issuer voluntarily takes any action that would result in selling Holders of the
Registrable Notes covered thereby or Participating Broker-Dealers seeking to
sell Exchange Notes not being able to sell such Registrable Notes or such
Exchange Notes during that period unless such action is required by applicable
law or permitted by this Agreement.

            (c) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto from whom the Company has
received written notice that it will be a Participating Broker-Dealer in the
applicable Exchange Offer, notify the selling Holders of Registrable Notes or
each such Participating Broker-Dealer, as the case may be, their counsel and the
managing underwriters, if any, promptly (but in any event within 2 business
days), and confirm such notice in writing, (i) when a Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon request, obtain, at the sole expense
of the Issuer, one conformed copy of such Registration Statement or
post-effective amendment including financial statements and schedules, documents
incorporated or deemed to be incorporated by reference and exhibits), (ii) of
the issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose,
(iii) if at any


                                       12
<PAGE>

time when a prospectus is required by the Securities Act to be delivered in
connection with sales of the Registrable Notes or resales of Exchange Notes by
Participating Broker-Dealers the representations and warranties of the Issuer
contained in any agreement (including any underwriting agreement) contemplated
by Section 5(l) hereof cease to be true and correct in all material respects,
(iv) of the receipt by the Issuer of any notification with respect to the
suspension of the qualification or exemption from qualification of a
Registration Statement or any of the Registrable Notes or the Exchange Notes to
be sold by any Participating Broker-Dealer for offer or sale in any
jurisdiction, or the initiation or written threat of any proceeding for such
purpose, (v) of the happening of any event, the existence of any condition or
any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in or amendments or supplements to such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Issuer's determination that a
post-effective amendment to a Registration Statement would be appropriate.

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

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


                                       13
<PAGE>

(iii) supplement or make amendments to such Registration Statement.

            (f) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, furnish to each selling Holder of
Registrable Notes and to each such Participating Broker-Dealer who so requests
and to their respective counsel and each managing underwriter, if any, at the
sole expense of the Issuer, one conformed copy of the Registration Statement or
Registration Statements and each post-effective amendment thereto, including
financial statements and schedules, and, if requested, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

            (g) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, deliver to each selling Holder of
Registrable Notes or each such Participating Broker-Dealer, as the case may be,
their respective counsel, and the underwriters, if any, at the sole expense of
the Issuer, as many copies of the Prospectus or Prospectuses (including each
form of preliminary prospectus) and each amendment or supplement thereto and any
documents incorporated by reference therein as such Persons may reasonably
request; and, subject to the last paragraph of this Section 5, the Issuer hereby
consents to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, and the underwriters or agents, if any, and
dealers (if any), in connection with the offering and sale of the Registrable
Notes covered by, or the sale by Participating Broker-Dealers of the Exchange
Notes pursuant to, such Prospectus and any amendment or supplement thereto.

            (h) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Registration Statement by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its best efforts to register or qualify, and to cooperate
with the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, the managing underwriter or underwriters, if
any, and their respective counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Notes for offer and sale under the securities or Blue Sky laws of
such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters reasonably request in
writing; provided, however, that where Exchange Notes held by Participating
Broker-Dealers or Registrable Notes are offered other than through an
underwritten offering, the Issuer agrees to cause its counsel to perform Blue
Sky


                                       14
<PAGE>

investigations and file registrations and qualifications required to be filed
pursuant to this Section 5(h), keep each such registration or qualification (or
exemption therefrom) effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things reasonably
necessary or advisable to enable the disposition in such jurisdictions of the
Exchange held by Participating Broker-Dealers or the Registrable Notes covered
by the Registration Statement; provided, however, that the Issuer shall not be
required to (A) qualify generally to do business in any jurisdiction where it is
not then so qualified, (B) take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject or
(C) subject itself to taxation in excess of a nominal dollar amount in any such
jurisdiction where it is not then so subject.

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

            (j) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, upon the occurrence of any event
contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable
prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole
expense of the Issuer, a supplement or post-effective amendment to the
applicable Registration Statement or a supplement to the related Prospectus or
any document incorporated or deemed to be incorporated therein by reference, or
file any other required document so that, as thereafter delivered to the
purchasers of the Registrable Notes being sold thereunder or to the purchasers
of the Exchange Notes to whom such Prospectus will be delivered by a
Participating Broker-Dealer, any such Prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Notwithstanding the
foregoing, the Issuer shall not be required to amend or supplement a
Registration Statement, any related Prospectus or any document incorporated
therein by reference, in the event that, and for a period not to exceed an
aggregate of 75 days in any calendar year if, (i) an event occurs and is
continuing as a result of which a Shelf Registration would, in the Issuer's good
faith judgment, contain an untrue statement of a material fact or omit to state
a material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading, and (ii) (a)
the Issuer determines in its good faith judgment that the disclosure of such
event at such time would have a material


                                       15
<PAGE>

adverse effect on the business, operations or prospects of the Issuer or (b) the
disclosure otherwise relates to a pending material business transaction that has
not yet been publicly disclosed.

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

            (l) in the case of a Shelf Registration, enter into such agreements
(including underwriting agreements) and take all such other appropriate actions
as are reasonably requested in order to expedite or facilitate the registration
or the disposition of such Registrable Notes, and in such connection, (i) make
such representations and warranties to Holders of such Registrable Notes with
respect to the business of the Issuer and its subsidiaries as then conducted and
the Registration Statement, Prospectus and documents, if any, incorporated or
deemed to be incorporated by reference therein, in each case, as are customarily
made by issuers to underwriters in underwritten offerings, and confirm the same
if and when requested; (ii) obtain an opinion of counsel to the Issuer and
updates thereof in form and substance reasonably satisfactory to the Holders of
a majority in principal amount of the Registrable Notes being sold, addressed to
each selling Holder covering the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably
requested by such Holders; (iii) obtain "cold comfort" letters and updates
thereof from the independent certified public accountants of the Issuer (and, if
necessary, any other independent certified public accountants of any subsidiary
of the Issuer or of any business acquired by any of the Issuer for which
financial statements and financial data are, or are required to be, included in
the Registration Statement), addressed to the selling Holders of Registrable
Notes that satisfy the applicable requirements of Statement of Accounting
Standards No. 72, such letters to be in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
underwritten offerings and such other matters as reasonably requested by such
selling Holders; and (iv) if an underwriting agreement is entered into, the same
shall contain indemnification provisions and procedures no less favorable than
those set forth in Section 7 hereof (or such other provisions and procedures
acceptable to the Issuer and the Holders of a majority in aggregate principal
amount of Registrable Notes covered by such Registration with respect to all
parties to be indemnified pursuant to said Section including, without
limitation, such selling Holders). The above shall be done at each closing in
respect of the sale of Registrable Notes, or as and to the extent required
thereunder.

            (m) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer


                                       16
<PAGE>

who seeks to sell Exchange Notes during the Applicable Period, make available
for inspection by any selling Holder of such Registrable Notes being sold, or
each such Participating Broker-Dealer, as the case may be, any underwriter
participating in any such disposition of Registrable Notes, if any, and any
attorney, accountant or other agent retained by any such selling Holder or each
such Participating Broker-Dealer, as the case may be, or underwriter
(collectively, the "Inspectors"), at the offices where normally kept, during
regular business hours and upon reasonable notice, all financial and other
records, pertinent corporate documents and instruments of the Issuer and
subsidiaries of the Issuer (collectively, the "Records") as shall be reasonably
necessary to enable them to exercise any applicable due diligence
responsibilities, and cause the officers, directors and employees of the Issuer
and any of its subsidiaries to supply all information reasonably requested by
any such Inspector in connection with such Registration Statement and
Prospectus. Each Inspector shall agree in writing that it will keep the Records
confidential and that it will not disclose any of the Records that the Issuer
determines, in good faith, to be confidential and notify the Inspectors in
writing are confidential unless (i) the disclosure of such Records is necessary
to avoid or correct a material misstatement or material omission in such
Registration Statement or Prospectus, (ii) the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction, or (iii) the information in such Records has been made generally
available to the public; provided, however, that prior notice shall be provided
as soon as practicable to the Issuer of the potential disclosure of any
information by such Inspector pursuant to clauses (i) or (ii) of this sentence
to permit the Issuer to obtain a protective order (or waive the provisions of
this paragraph (m)) and that such Inspector shall take such actions as are
reasonably necessary to protect the confidentiality of such information (if
practicable) to the extent such action is otherwise not inconsistent with, an
impairment of or in derogation of the rights and interests of the Holder or any
Inspector.

            (n) Provide an indenture trustee for the Registrable Notes or the
Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Registrable Notes; and in connection
therewith, cooperate with the trustee under any such indenture and the Holders
of the Registrable Notes, to effect such changes to such indenture as may be
required for such indenture to be so qualified in accordance with the terms of
the TIA; and execute, and use their best efforts to cause such trustee to
execute, all documents as may be required to effect such changes, and all other
forms and documents required to be filed with the SEC to enable such indenture
to be so qualified in a timely manner.

            (o) Comply with all applicable rules and regulations of the SEC and
make generally available to their securityholders with regard to any applicable
Registration Statement, a consolidated earning statement satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or
any similar rule promulgated under the Securities


                                       17
<PAGE>

Act) no later than 45 days after the end of any twelve-month period (or 90 days
after the end of any 12-month period if such period is a fiscal year) (i)
commencing at the end of any fiscal quarter in which any Registrable Notes are
sold to underwriters in a firm commitment or best efforts underwritten offering
and (ii) if not sold to underwriters in such an offering, commencing on the
first day of the first fiscal quarter of the Issuer after the effective date of
a Registration Statement, which statements shall cover said 12-month periods.

            (p) Upon consummation of an Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Issuer addressed to the Trustee for the
benefit of all Holders of Registrable Notes participating in the Exchange Offer
or Private Exchange, as the case may be, that the Exchange Notes or Private
Exchange Notes as the case may be, and the related indenture constitute legal,
valid and binding obligations of the Issuer, enforceable against it in
accordance with their respective terms subject to customary exceptions and
qualifications.

            (q) If the Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Notes by Holders to the Issuer (or
to such other Person as directed by the Issuer) in exchange for the Exchange
Notes or the Private Exchange Notes, as the case may be, the Issuer shall mark,
or cause to be marked, on such Registrable Notes that such Registrable Notes are
being canceled in exchange for the Exchange Notes or the Private Exchange Notes,
as the case may be; provided that in no event shall such Registrable Notes be
marked as paid or otherwise satisfied.

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

            (s) Use its best efforts to take all other steps reasonably
necessary to effect the registration of the applicable Registrable Notes covered
by a Registration Statement contemplated hereby.

            The Issuer may require each seller of any Registrable Notes as to
which any registration is being effected to furnish to the Issuer such
information regarding such seller and the distribution of such Registrable Notes
as the Issuer may, from time to time, reasonably request. The Issuer may exclude
from such registration the Registrable Notes of any seller for so long as such
seller fails to furnish such information within a reasonable time after
receiving such request and in such event shall have no further obligation under
this Agreement (including without limitation the obligation under Section 4)
with respect to such seller or any subsequent holder of such Registrable Notes.
Each seller as to which any Shelf Registration is being effected agrees to
furnish promptly to the Issuer all information required to be disclosed in order
to make the information previously furnished to the Issuer by such


                                       18
<PAGE>

seller not materially misleading.

            If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Issuer, then such Holder shall
have the right to require (i) the insertion therein of language, in form and
substance reasonably satisfactory to such Holder, to the effect that the holding
by such Holder of such securities is not to be construed as a recommendation by
such Holder of the investment quality of the securities covered thereby and that
such holding does not imply that such Holder will assist in meeting any future
financial requirements of the Issuer, or (ii) in the event that such reference
to such Holder by name or otherwise is not required by the Securities Act or any
similar federal statute then in force, the deletion of the reference to such
Holder in any amendment or supplement to the applicable Registration Statement
filed or prepared subsequent to the time that such reference ceases to be
required.

            Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange
Notes, as the case may be, to be sold by such Participating Broker-Dealer, as
the case may be, that, upon actual receipt of any notice from the Issuer of the
happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv),
5(c)(v), or 5(c)(vi) hereof, such Holder or Participating Broker-Dealer, as the
case may be, will forthwith discontinue disposition of such Registrable Notes or
Exchange Notes, as the case may be, covered by such Registration Statement or
Prospectus until such Holder's or Participating Broker-Dealer's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 5(j)
hereof, or until it is advised in writing (the "Advice") by the Issuer that the
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto. In the event that the Issuer shall give any
such notice, the Applicable Period shall be extended by the number of days
during such periods from and including the date of the giving of such notice to
and including the date when each seller of Registrable Notes covered by such
Registration Statement or Exchange Notes to be sold by such Participating
Broker-Dealer, as the case may be, shall have received (x) the copies of the
supplemented or amended Prospectus contemplated by Section 5(j) hereof or (y)
the Advice.

            6. Registration Expenses.

            All fees and expenses incident to the performance of or compliance
with this Agreement by the Issuer (other than any underwriting discounts or
commissions) shall be borne by the Issuer whether or not the Exchange
Registration Statement or any Shelf Registration is filed or becomes effective
or the Exchange Offer is consummated, including, without limitation, (i) all
registration and filing fees (including, without limitation, (A) fees with
respect to filings required to be made with the NASD in connection with an
underwritten offering and (B) fees and expenses of compliance with state
securities or Blue Sky laws (including, without limitation, reasonable fees and
disbursements of counsel in connection


                                       19
<PAGE>

with Blue Sky qualifications of the Registrable Notes or Exchange Notes and
determination of the eligibility of the Registrable Notes or Exchange Notes for
investment under the laws of such jurisdictions (x) where the holders of
Registrable Notes or Exchange Notes, as the case may be, are located, or (y) as
provided in Section 5(h) hereof, in the case of Registrable Notes or Exchange
Notes, as the case may be, to be sold by a Participating Broker-Dealer during
the Applicable Period)), (ii) printing expenses, including, without limitation,
expenses of printing certificates for Registrable Notes or Exchange Notes in a
form eligible for deposit with The Depository Trust Company and of printing
prospectuses if the printing of prospectuses is requested by the managing
underwriter or underwriters, if any, by the Holders of a majority in aggregate
principal amount of the Registrable Notes included in any Registration Statement
or to be sold by any Participating Broker-Dealer, as the case may be, (iii)
messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Issuer and fees and disbursements of one special counsel for all
of the sellers of each of the Registrable Notes (exclusive of any counsel
retained pursuant to Section 7 hereof), (v) fees and disbursements of all
independent certified public accountants referred to in Section 5(l)(iii) hereof
(including, without limitation, the expenses of any special audit and "cold
comfort" letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Issuer desires such insurance, (vii) fees and
expenses of all other Persons retained by the Issuer, (viii) internal expenses
of the Issuer (including, without limitation, all salaries and expenses of
officers and employees of the Issuer performing legal or accounting duties),
(ix) the expense of any annual audit, (x) any fees and expenses incurred in
connection with the listing of the securities to be registered on any securities
exchange, and the obtaining of a rating of the securities, in each case, if
applicable, and (xi) the expenses relating to printing, word processing and
distributing all Registration Statements, underwriting agreements, indentures
and any other documents necessary in order to comply with this Agreement.

            7. Indemnification and Contribution.

            (a) The Issuer agrees to indemnify and hold harmless each Holder of
the Registrable Notes and each Participating Broker-Dealer selling the Exchange
Notes during the Applicable Period, the affiliates, officers and directors of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "Participant"), from and against any and all losses,
claims, damages, judgments, liabilities and expenses (including, without
limitation, the legal fees and other expenses actually incurred in connection
with any suit, action or proceeding or any claim asserted) caused by, arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if the Issuer shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by,
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements


                                       20
<PAGE>

therein, in the case of the Prospectus in the light of the circumstances under
which they were made, not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
information relating to any Participant furnished to the Issuer in writing by
such Participant expressly for use therein and with respect to any preliminary
Prospectus, to the extent that any such loss, claim, damage or liability arises
solely from the fact that any Participant sold Registrable Notes or Exchange
Notes to a person to whom there was not sent or given a copy of the Prospectus
(as amended or supplemented) at or prior to the written confirmation of such
sale if the Issuer shall have previously furnished copies thereof to the
Participant in accordance herewith and the Prospectus (as amended or
supplemented) would have corrected any such untrue statement or omission.

            (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Issuer, the affiliates, officers and directors of the
Issuer and each Person who controls the Issuer within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act to the same extent (but
on a several, and not joint, basis) as the foregoing indemnity from the Issuer
to each Participant, but only with reference to information relating to such
Participant furnished to the Issuer in writing by or on behalf of such
Participant expressly for use in any Registration Statement or Prospectus, any
amendment or supplement thereto, or any preliminary prospectus. The liability of
any Participant under this paragraph shall in no event exceed the proceeds
received by such Participant from sales of Registrable Notes or Exchange Notes
giving rise to such obligations.

            (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such Person (the "Indemnified Person") shall promptly
notify the Persons against whom such indemnity may be sought (the "Indemnifying
Persons") in writing, and the Indemnifying Persons, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Persons may reasonably designate in such proceeding and shall pay
the fees and expenses actually incurred by such counsel related to such
proceeding; provided, however, that the failure to so notify the Indemnifying
Persons will not relieve it from any liability under paragraph (a) or (b) above
unless and to the extent such failure results in the forfeiture by the
Indemnifying Person of substantial rights and defenses and the Indemnifying
Person was not otherwise aware of such action or claim. In any such proceeding,
any Indemnified Person shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Person unless (i) the Indemnifying Persons and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed
within a reasonable period of time to retain counsel reasonably satisfactory to
the Indemnified Person or (iii) the named parties in any such proceeding


                                       21
<PAGE>

(including any impleaded parties) include both any Indemnifying Person and the
Indemnified Person or any affiliate thereof and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Persons shall
not, in connection with such proceeding or separate but substantially similar
related proceedings in the same jurisdiction arising out of the same general
allegations, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed promptly as they are incurred. Any
such separate firm for the Participants and such control Persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Notes and Exchange Notes sold by all such Participants and shall
be reasonably acceptable to the Issuer, and any such separate firm for the
Issuer, their affiliates, officers, directors, representatives, employees and
agents and such control Persons of the Issuer shall be designated in writing by
the Issuer and shall be reasonably acceptable to the Holders.

            The Indemnifying Persons shall not be liable for any settlement of
any proceeding effected without its prior written consent (which consent shall
not be unreasonably withheld or delayed), but if settled with such consent or if
there be a final non-appealable judgment for the plaintiff for which the
Indemnified Person is entitled to indemnification pursuant to this Agreement,
each of the Indemnifying Persons agrees to indemnify and hold harmless each
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Person shall, without the prior written
consent of the Indemnified Persons (which consent shall not be unreasonably
withheld or delayed), effect any settlement or compromise of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party, or indemnity could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional written
release of such Indemnified Person, in form and substance reasonably
satisfactory to such Indemnified Person, from all liability on claims that are
the subject matter of such proceeding and (B) does not include any statement as
to an admission of fault, culpability or failure to act by or on behalf of such
Indemnified Person.

            (d) If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as


                                       22
<PAGE>

well as any other relevant equitable considerations. The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Issuer
on the one hand or such Participant or such other Indemnified Person, as the
case may be, on the other, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission,
and any other equitable considerations appropriate in the circumstances.

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

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

            8. Rules 144 and 144A.

            The Issuer covenants and agrees that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and,
if at any time the Issuer is not required to file such reports, the Issuer will,
upon the request of any Holder or beneficial owner of Registrable Notes, make
available such information necessary to permit sales pursuant to Rule 144A under
the Securities Act. The Issuer further covenants and agrees, for so long as any
Registrable Notes remain outstanding that it will take such further action as
any Holder of Registrable Notes may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Notes
without registration under the Securities Act within the limitation of the


                                       23
<PAGE>

exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act,
as such Rules may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC.

            9. Miscellaneous.

            (a) No Inconsistent Agreements. The Issuer has not, as of the date
hereof, and the Issuer shall not, after the date of this Agreement, enter into
any agreement with respect to any of their securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Issuer's other issued and outstanding
securities under any such agreements. The Issuer will not enter into any
agreement with respect to any of its securities which will grant to any Person
piggy-back registration rights with respect to any Registration Statement.

            (b) Adjustments Affecting Registrable Securities. The Issuer shall
not, directly or indirectly, take any action with respect to the Registrable
Notes that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

            (c) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (I) the Issuer and (II)(A) the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Notes and (B) in
circumstances that would adversely affect the Participating Broker-Dealers, the
Participating Broker-Dealers holding not less than a majority in aggregate
principal amount or liquidation preference, as the case may be, of the Exchange
Notes held by all Participating Broker-Dealers; provided, however, that Section
7 and this Section 10(c) may not be amended, modified or supplemented without
the prior written consent of each Holder and each Participating Broker-Dealer
(including any person who was a Holder or Participating Broker-Dealer of
Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to
any Registration Statement) affected by any such amendment, modification or
supplement. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders of Registrable Notes whose securities are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect,
impair, limit or compromise the rights of other Holders of Registrable Notes may
be given by Holders of at least a majority in aggregate principal amount of the
Registrable Notes being sold pursuant to such Registration Statement.

            (d) Notices. All notices and other communications (including,
without


                                       24

limitation, any notices or other communications to the Trustee) provided for or

      Broker-Dealer, as the case may be, set forth on the records of the
      registrar under the Indenture, the Exchange Indenture or of the Issuer, as
      appropriate.

            (ii) if to the Issuer, at the address as follows:

             FLAG Telecom Holdings Limited
             3rd Floor, 103 Mount Street

             Attention: Stuart Rubin, General Counsel

            All such notices and communications shall be deemed to have been
duly given: when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; one business day
after being timely delivered to a next-day air courier; and when receipt is
acknowledged by the addressee, if sent by facsimile.

            Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee at the
address and in the manner specified in the Indenture if such communication
relates to the Notes, Exchange Notes or Private Exchange Notes.

            (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
hereto, the Holders and the Participating Broker-Dealers; provided, however,
that this Agreement shall not inure to the benefit of or be binding upon a
successor or assign of a Holder or a Participating Broker-Dealer unless and to
the extent such successor or assign holds Registrable Notes.

            (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

            (g) Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

            (h) Governing Law. THIS AGREEMENT SHALL BE GOVERNED


                                       25
<PAGE>

BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS
APPLIED TO CONTRACTS MADE AND PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK,
WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO
AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN
ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

            (i) Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

            (j) Securities Held by the Issuer or Its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable Notes is
required hereunder, Registrable Notes held by the Issuer or its affiliates (as
such term is defined in Rule 405 under the Securities Act) shall not be counted
in determining whether such consent or approval was given by the Holders of such
required percentage.

            (k) Third-Party Beneficiaries. Holders of Registrable Notes, and
Participating Broker-Dealers are intended third-party beneficiaries of this
Agreement, and this Agreement may be enforced by such Persons.

            (l) Entire Agreement. This Agreement, the Purchase Agreement and the
Indenture are intended by the parties as a final and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject
matter contained herein and therein and any and all prior oral or written
agreements, representations, or warranties, contracts, understandings,
correspondence, conversations and memoranda between the Holders on the one hand
and the Issuer on the other, or between or among any agents, representatives,
parents, subsidiaries, affiliates, predecessors in interest or successors in
interest with respect to the subject matter hereof and thereof are merged herein
and replaced hereby.

                             REGISTRATION AGREEMENT

            This Registration Agreement (this "Agreement") is dated as of March
17, 2000, by and among FLAG TELECOM HOLDINGS LIMITED, a Bermuda corporation (the
"Company" or the "Issuer), as issuer, and SALOMON SMITH BARNEY INC., MORGAN
STANLEY & CO. INTERNATIONAL LIMITED, DEUTSCHE BANK SECURITIES INC. AND BEAR,
STEARNS & CO. INC., as Initial Purchasers (the "Initial Purchasers").

            This Agreement is entered into in connection with the Purchase
Agreement, dated March 14, 2000, by and among the Company and the Initial
Purchasers (the "Purchase Agreement"), which provides for, among other things,
the sale by the Company to the Initial Purchasers of $300 million aggregate
principal amount of the Company's 11.625% Senior Dollar Notes due 2010 (the
"Notes") and (euro)300 million aggregate principal amount of the Company's
11.625% Senior Euro Notes due 2010. In order to induce the Initial Purchasers to

governing the Exchange Notes and Private Exchange Notes.

            Underwritten registration or underwritten offering: A registration
in which securities of the Issuer are sold to an underwriter for reoffering to
the public.

            2. Exchange Offer.

            (a) The Issuer shall (A) prepare and, on or prior to 60 days after
the Issue Date (the "Exchange Filing Date"), file with the SEC a Registration
Statement under the Securities Act with respect to an offer by the Company to
the holders of the Notes to issue and deliver to such holders, in exchange for
Notes, a like principal amount of Exchange Notes (the "Exchange Offer"), (B) use
its best efforts to cause the Registration Statement relating to the Exchange
Offer to be declared effective by the SEC under the Securities Act on or prior
to 150 days after the Issue Date (the "Exchange Effectiveness Date") and (C)
commence the Exchange Offer and use its best efforts to issue, on or prior to
180 days after the Issue Date, the Exchange Notes. The offer and sale of the
Exchange Notes pursuant to the Exchange Offer shall be registered pursuant to
the Securities Act on the appropriate form (the "Exchange Registration
Statement") and duly registered or qualified under all applicable state
securities or Blue Sky laws and will comply with all applicable tender offer
rules and regulations under the Exchange Act and state securities or Blue Sky
laws. The Exchange Offer shall not be subject to any condition, other than that
the Exchange Offer does not violate any applicable law or interpretation of the
staff of the SEC. Upon consummation of the Exchange Offer in accordance with
this Section 2, the Issuer shall have no further registration obligations other
than with respect to (i) Private Exchange Notes, (ii) Exchange Notes held by
Participating Broker-Dealers and (iii) Notes or Exchange Notes as to which
Section 3 hereof applies. No securities shall be included in the Exchange
Registration Statement other than the Exchange Notes.

            (b) The Issuer may require each holder of Notes as a condition to
its participation in the Exchange Offer to represent to the Issuer and its
counsel in writing (which may be contained in the applicable letter of
transmittal) that at the time of the consummation of the Exchange Offer (i) any
Exchange Notes received by such holder will be acquired in the ordinary course
of its business, (ii) such holder will have no arrangement or understanding with
any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes and (iii) such holder is not an Affiliate
of the Issuer, or if it is an Affiliate of the Issuer, it will comply with the
registration and prospectus delivery requirements of the Securities Act, to the
extent applicable.

            If, prior to consummation of the Exchange Offer, an Initial
Purchaser holds any Notes acquired by it and having, or that are reasonably
likely to be determined to have, the status of an unsold allotment in the
initial distribution, or any other holder of Notes is not entitled to
participate in the Exchange Offer, the Company upon the request of such Initial


                                       5
<PAGE>

Purchaser or any such holder shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to such Initial
Purchaser and any such holder, in exchange (the "Private Exchange") for such
Notes held by such Initial Purchaser and any such holder, a like principal
amount of debt securities of the Company, that are identical in all material
respects to the Exchange Notes (the "Private Exchange Notes") (and that are
issued pursuant to the same indenture as the Exchange Notes). The Private
Exchange Notes shall bear the same CUSIP number as the Exchange Notes.

            The Issuer and the Initial Purchasers acknowledge that the staff of
the SEC has taken the position that any broker-dealer that owns Exchange Notes
that were received by such broker-dealer for its own account in the Exchange
Offer (a "Participating Broker-Dealer") may be deemed to be an "underwriter"
within the meaning of the Securities Act and must deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such
Exchange Notes (other than a resale of an unsold allotment resulting from the
original offering of the Notes).

            The Issuer and the Initial Purchasers also acknowledge that it is
the SEC staff's position that if the Prospectus contained in the Exchange
Registration Statement includes a plan of distribution containing a statement to
the above effect and the means by which Participating Broker-Dealers may resell
the Exchange Notes, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Notes owned by them, such Prospectus may be
delivered by Participating Broker-Dealers to satisfy their prospectus delivery
obligations under the Securities Act in connection with resales of Exchange
Notes for their own accounts, so long as the Prospectus otherwise meets the
requirements of the Securities Act.

            In light of the foregoing, if requested by a Participating
Broker-Dealer, the Issuer agrees (x) to use its best efforts to keep the
Exchange Registration Statement continuously effective for a period of up to six
months or such earlier date as each Participating Broker-Dealer shall have
notified the Company in writing that such Participating Broker-Dealer has resold
all Exchange Notes acquired in the Exchange Offer, (y) to comply with the
provisions of Section 5 of this Agreement, as they relate to the Exchange Offer
and the Exchange Registration Statement, and (z) to deliver to such
Participating Broker-Dealer a "cold comfort" letter of the independent public
accountants of the Issuer and a legal opinion as to matters reasonably requested
by such Participating Broker-Dealer relating to the Exchange Registration
Statement and the related Prospectus and any amendments or supplements thereto.

            Interest on the Exchange Notes and the Private Exchange Notes will
accrue from (A) the later of (i) the last interest payment date on which
interest was paid on the Notes surrendered in exchange therefor and (ii) if the
Notes are surrendered for exchange on a date in a period which includes the
record date for an interest payment date to occur on or after the


                                       6
<PAGE>

date of such exchange and as to which interest will be paid, the date of such
interest payment date or (B), if no interest has been paid on the Notes, from
the Issue Date.

In connection with each Exchange Offer, the Issuer shall:

            (1) mail, or cause to be mailed, to each Holder of record entitled
      to participate in the Exchange a copy of the Prospectus forming part of
      the Exchange Registration Statement, together with an appropriate letter
      of transmittal and related documents;

            (2) use their best efforts to keep the Exchange Offer open for not
      less than 20 business days after the date that notice of the Exchange
      Offer is mailed to Holders (or longer if required by applicable law);

            (3) utilize the services of a depositary for the Exchange Offer with
      an address in the Borough of Manhattan, The City of New York;

            (4) permit Holders to withdraw validly tendered Notes at any time
      prior to the close of business, New York time, on the last business day on
      which the Exchange Offer shall remain open; and

            (5) otherwise comply in all material respects with all applicable
      laws, rules and regulations.

            As soon as practicable after the close of the applicable Exchange
Offer and the applicable Private Exchange, if any, the Issuer shall:

            (1) accept for exchange all Registrable Notes validly tendered and
      not validly withdrawn pursuant to the applicable Exchange Offer and the
      applicable Private Exchange, if any;

            (2) deliver to the Trustee for cancellation all Registrable Notes so
      accepted for exchange and cause the Trustee to authenticate and deliver
      promptly to each Holder of Registrable Notes, Exchange Notes or Private
      Exchange Notes, as the case may be, equal in principal amount to the
      securities of such Holder so accepted for exchange.

            The Exchange Notes and the Private Exchange Notes shall be issued
under (i) the Indenture or (ii) an indenture identical in all material respects
to the Indenture and that, in either case, has been qualified under the TIA or
is exempt from such qualification and shall provide that (a) the Exchange Notes
shall not be subject to the transfer restrictions set forth in the Indenture and
(b) the Private Exchange Notes shall be subject to the transfer restrictions


                                       7
<PAGE>

set forth in such indenture. The Indenture or such indenture shall provide that
the Exchange Notes, the Private Exchange Notes and the Notes shall vote and
consent together on all matters as one class and that none of the Exchange
Notes, the Private Exchange Notes or the Notes will have the right to vote or
consent as a separate class on any matter.

            (c) If, (i) because of any change in law or in currently prevailing
interpretations of the staff of the SEC, the Issuer is not permitted to effect
the Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days
of the Issue Date, (iii) any holder of any Private Exchange Notes so requests in
writing to the Issuer within 45 days after the consummation of the Exchange
Offer, or (iv) in the case of any Holder that participates in the Exchange
Offer, such Holder does not receive Exchange Notes on the date of the exchange
that may be sold without restriction under state and federal securities laws
(other than due solely to the status of such Holder as an affiliate of the
Issuer within the meaning of the Securities Act), then in the case of each of
clauses (i) to and including (iv) of this sentence, the Issuer shall promptly
deliver to the Holders and the Trustee written notice thereof (the "Shelf
Notice") and shall file a Shelf Registration pursuant to Section 3 hereof.

            3. Shelf Registration.

            If at any time a Shelf Notice is delivered as contemplated by
Section 2(c) hereof, then:

            (a) Shelf Registration. The Issuer shall file with the SEC a
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange
Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is
applicable (the "Initial Shelf Registration"). The Issuer shall use its best
efforts to file with the SEC the Initial Shelf Registration on or before the
60th day after the occurrence of any of the events set forth in Section 2(c)
(the "Initial Shelf Registration Filing Date"). The Initial Shelf Registration
shall be on Form F-1 or another appropriate form permitting registration of such
Registrable Notes for resale by Holders in the manner or manners designated by
them (including, without limitation, one or more underwritten offerings). The
Issuer shall not permit any securities other than the Registrable Notes to be
included in the Initial Shelf Registration or any Subsequent Shelf Registration
(as defined below).

            The Issuer shall use its best efforts to cause the Initial Shelf
Registration to be declared effective under the Securities Act on or prior to
the 90th day after the Initial Shelf Registration Filing Date (the "Initial
Shelf Registration Effectiveness Date") and to keep the Initial Shelf
Registration continuously effective under the Securities Act until the date
which is the earlier of (a) two years from the Issue Date (the "Effectiveness
Period") and (b) such shorter period ending when (i) all Registrable Notes
covered by the Initial Shelf Registration have been sold in the manner set forth
and as contemplated in the Initial Shelf Registration or


                                       8
<PAGE>

(ii) a Subsequent Shelf Registration covering all of the Registrable Notes
covered by and not sold under the Initial Shelf Registration or an earlier
Subsequent Shelf Registration has been declared effective under the Securities
Act (the "Applicable Period"); provided, however, that the Effectiveness Period
in respect of the Initial Shelf Registration shall be extended to the extent
required to permit dealers to comply with the applicable prospectus delivery
requirements of Rule 174 under the Securities Act and as otherwise provided
herein.

            (b) Subsequent Shelf Registrations. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Issuer shall use its
best efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 30 days of such cessation
of effectiveness amend the Initial Shelf Registration in a manner to obtain the
withdrawal of the order suspending the effectiveness thereof, or file an
additional "shelf" Registration Statement pursuant to Rule 415 covering all of
the Registrable Notes covered by and not sold under the Initial Shelf
Registration or an earlier Subsequent Shelf Registration (each, a "Subsequent
Shelf Registration"). If a Subsequent Shelf Registration is filed, the Issuer
shall use its best efforts to cause the Subsequent Shelf Registration to be
declared effective under the Securities Act as soon as practicable after such
filing and to keep such subsequent Shelf Registration continuously effective for
the remainder of the Effectiveness Period. As used herein the term "Shelf
Registration" means the Initial Shelf Registration and any Subsequent Shelf
Registration.

            (c) Supplements and Amendments. The Issuer shall promptly supplement
and amend any Shelf Registration if required by the rules, regulations or
instructions applicable to the registration form used for such Shelf
Registration, if required by the Securities Act, or if reasonably requested by
the Holders of a majority in aggregate principal amount of the Registrable Notes
covered by such Registration Statement or by any underwriter of such Registrable
Notes.

            4. Additional Interest.

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

            (i) if (A) neither the Exchange Registration Statement nor the
      Initial Shelf Registration has been filed on or prior to the applicable
      Filing Date or (B) notwithstanding that the Issuer has consummated or will
      consummate the


                                       9
<PAGE>

      Exchange Offer, the Issuer is required to file a Shelf Registration and
      such Shelf Registration is not filed on or prior to the Filing Date
      applicable thereto, then commencing on the day after any such Filing Date,
      Additional Interest shall accrue on the principal amount of the Notes at a
      rate of 0.25% per annum for the first 30 days immediately following each
      such Filing Date, and such Additional Interest shall increase by an
      additional 0.25% per annum at the beginning of each subsequent 30-day
      period; or

            (ii) if (A) neither the Exchange Registration Statement nor the
      Initial Shelf Registration is declared effective by the SEC on or prior to
      the relevant Effectiveness Date or (B) notwithstanding that the Issuer has
      consummated or will consummate the Exchange Offer, the Issuer is required
      to file a Shelf Registration and such Shelf Registration is not declared
      effective by the SEC on or prior to the Effectiveness Date in respect of
      such Shelf Registration, then, commencing on the day after the applicable
      Effectiveness Date, Additional Interest shall accrue on the principal
      amount of the Notes at a rate of 0.25% per annum for the first 30 days
      immediately following the day after such Effectiveness Date, and the rate
      of such Additional Interest shall increase by an additional 0.25% per
      annum at the beginning of each subsequent 30-day period; or

            (iii) if (A) the Issuer has not exchanged Exchange Notes for all
      Notes validly tendered in accordance with the terms of the Exchange Offer
      on or prior to the 180th day after the Issue Date or (B) if applicable, a
      Shelf Registration has been declared effective and such Shelf Registration
      ceases to be effective at any time during the Effectiveness Period (other
      than such time as all Notes have been disposed of thereunder), then
      Additional Interest shall accrue on the principal amount of the Notes at a
      rate of 0.25% per annum for the first 30 days commencing on the (x) 181st
      day after such Issue Date, in the case of (A) above, or (y) the day such
      Shelf Registration ceases to be effective in the case of (B) above, such
      Additional Interest shall increase by an additional 0.25% per annum at the
      beginning of each such subsequent 30-day period (it being understood and
      agreed that, notwithstanding any provision to the contrary, so long as any
      Note that is the subject of a Shelf Notice is then covered by an effective
      Shelf Registration, no Additional Interest shall accrue or accumulate on
      such Notes);

provided, however, that the rate of Additional Interest that shall accrue on the
Notes may not exceed in the aggregate 1.50% per annum; provided, further,
however, that (1) upon the filing of the applicable Exchange Registration
Statement or the applicable Shelf Registration as required hereunder (in the
case of clause (i) above of this Section 4(a)), (2) upon the effectiveness of
the applicable Exchange Registration Statement or the applicable Shelf
Registration Statement as required hereunder (in the case of clause (ii) of this
Section 4(a)), or (3) upon the exchange of the applicable Exchange Notes for all
Notes tendered (in the case of


                                       10
<PAGE>

clause (iii)(A) of this Section 4(a), or upon the effectiveness of the
applicable Shelf Registration Statement which had ceased to remain effective (in
the case of (iii)(B) of this Section 4(a)), Additional Interest on the Notes in
respect of which such events relate as a result of such clause (or the relevant
subclause thereof), as the case may be, shall cease to accrue or accumulate, as
the case may be.

            (b) The Issuer shall notify the Trustee (who shall be acting under
and protected by the terms of the Indenture) within three business days after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date"). Any amounts of Additional
Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 shall be
payable in cash semiannually on each March 30 and September 30 (to the holders
of record on the March 15 and September 15 immediately preceding such dates),
commencing with the first such date occurring after any such Additional Interest
commences to accrue. The amount of Additional Interest will be determined by
multiplying the applicable rate of Additional Interest by the principal amount
of the Registrable Notes, multiplied by a fraction, the numerator of which is
the number of days such rate of Additional Interest was applicable during such
period (determined on the basis of a 360-day year comprised of twelve 30-day
months and, in the case of a partial month, the actual number of days elapsed),
and the denominator of which is 360.

            5. Registration Procedures.

            In connection with the filing of any Registration Statement pursuant
to Sections 2 or 3 hereof, the Issuer shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuer hereunder, the Issuer shall:

            (a) Prepare and file with the SEC prior to the applicable Filing
Date, a Registration Statement or Registration Statements as prescribed by
Sections 2 or 3 hereof, and use its best efforts to cause each such Registration
Statement to become effective and remain effective as provided herein; provided,
however, that, if (1) such filing is pursuant to Section 3 hereof, or (2) a
Prospectus contained in the Exchange Registration Statement filed pursuant to
Section 2 hereof is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period relating thereto, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, the Issuer shall furnish to
and afford the Holders of the Registrable Notes included in such Registration
Statement or each such Participating Broker-Dealer, as the case may be, their
counsel and the managing underwriters, if any, a reasonable opportunity to
review copies of all such documents (including copies of any documents to be
incorporated by reference therein and all exhibits thereto) proposed to be filed
(in each case at least five days prior to such filing, or such later date as is
reasonable under the


                                       11
<PAGE>

circumstances). The Issuer shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in aggregate principal amount of the Registrable Notes included in such
Registration Statement, or any such Participating Broker-Dealer, as the case may
be, their counsel, or the managing underwriters, if any, shall reasonably object
in writing on a timely basis.

            (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration Statement or Exchange Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented by
any prospectus supplement required by applicable law, and as so supplemented to
be filed pursuant to Rule 424 (or any similar provisions then in force)
promulgated under the Securities Act; and comply with the provisions of the
Securities Act and the Exchange Act applicable to it with respect to the
disposition of all securities covered by such Registration Statement as so
amended or in such Prospectus as so supplemented and with respect to the
subsequent resale of any securities being sold by a Participating Broker-Dealer
covered by any such Prospectus. The Issuer shall be deemed not to have used its
best efforts to keep a Registration Statement effective during the Effectiveness
Period or the Applicable Period, as the case may be, relating thereto if the
Issuer voluntarily takes any action that would result in selling Holders of the
Registrable Notes covered thereby or Participating Broker-Dealers seeking to
sell Exchange Notes not being able to sell such Registrable Notes or such
Exchange Notes during that period unless such action is required by applicable
law or permitted by this Agreement.

            (c) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto from whom the Company has
received written notice that it will be a Participating Broker-Dealer in the
applicable Exchange Offer, notify the selling Holders of Registrable Notes or
each such Participating Broker-Dealer, as the case may be, their counsel and the
managing underwriters, if any, promptly (but in any event within 2 business
days), and confirm such notice in writing, (i) when a Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon request, obtain, at the sole expense
of the Issuer, one conformed copy of such Registration Statement or
post-effective amendment including financial statements and schedules, documents
incorporated or deemed to be incorporated by reference and exhibits), (ii) of
the issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose,
(iii) if at any


                                       12
<PAGE>

time when a prospectus is required by the Securities Act to be delivered in
connection with sales of the Registrable Notes or resales of Exchange Notes by
Participating Broker-Dealers the representations and warranties of the Issuer
contained in any agreement (including any underwriting agreement) contemplated
by Section 5(l) hereof cease to be true and correct in all material respects,
(iv) of the receipt by the Issuer of any notification with respect to the
suspension of the qualification or exemption from qualification of a
Registration Statement or any of the Registrable Notes or the Exchange Notes to
be sold by any Participating Broker-Dealer for offer or sale in any
jurisdiction, or the initiation or written threat of any proceeding for such
purpose, (v) of the happening of any event, the existence of any condition or
any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in or amendments or supplements to such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Issuer's determination that a
post-effective amendment to a Registration Statement would be appropriate.

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

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


                                       13
<PAGE>

(iii) supplement or make amendments to such Registration Statement.

            (f) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, furnish to each selling Holder of
Registrable Notes and to each such Participating Broker-Dealer who so requests
and to their respective counsel and each managing underwriter, if any, at the
sole expense of the Issuer, one conformed copy of the Registration Statement or
Registration Statements and each post-effective amendment thereto, including
financial statements and schedules, and, if requested, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

            (g) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, deliver to each selling Holder of
Registrable Notes or each such Participating Broker-Dealer, as the case may be,
their respective counsel, and the underwriters, if any, at the sole expense of
the Issuer, as many copies of the Prospectus or Prospectuses (including each
form of preliminary prospectus) and each amendment or supplement thereto and any
documents incorporated by reference therein as such Persons may reasonably
request; and, subject to the last paragraph of this Section 5, the Issuer hereby
consents to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, and the underwriters or agents, if any, and
dealers (if any), in connection with the offering and sale of the Registrable
Notes covered by, or the sale by Participating Broker-Dealers of the Exchange
Notes pursuant to, such Prospectus and any amendment or supplement thereto.

            (h) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Registration Statement by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its best efforts to register or qualify, and to cooperate
with the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, the managing underwriter or underwriters, if
any, and their respective counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Notes for offer and sale under the securities or Blue Sky laws of
such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters reasonably request in
writing; provided, however, that where Exchange Notes held by Participating
Broker-Dealers or Registrable Notes are offered other than through an
underwritten offering, the Issuer agrees to cause its counsel to perform Blue
Sky


                                       14
<PAGE>

investigations and file registrations and qualifications required to be filed
pursuant to this Section 5(h), keep each such registration or qualification (or
exemption therefrom) effective during the period such Registration Statement is
required to be kept effective and do any and all other acts or things reasonably
necessary or advisable to enable the disposition in such jurisdictions of the
Exchange held by Participating Broker-Dealers or the Registrable Notes covered
by the Registration Statement; provided, however, that the Issuer shall not be
required to (A) qualify generally to do business in any jurisdiction where it is
not then so qualified, (B) take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject or
(C) subject itself to taxation in excess of a nominal dollar amount in any such
jurisdiction where it is not then so subject.

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

            (j) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, upon the occurrence of any event
contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable
prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole
expense of the Issuer, a supplement or post-effective amendment to the
applicable Registration Statement or a supplement to the related Prospectus or
any document incorporated or deemed to be incorporated therein by reference, or
file any other required document so that, as thereafter delivered to the
purchasers of the Registrable Notes being sold thereunder or to the purchasers
of the Exchange Notes to whom such Prospectus will be delivered by a
Participating Broker-Dealer, any such Prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. Notwithstanding the
foregoing, the Issuer shall not be required to amend or supplement a
Registration Statement, any related Prospectus or any document incorporated
therein by reference, in the event that, and for a period not to exceed an
aggregate of 75 days in any calendar year if, (i) an event occurs and is
continuing as a result of which a Shelf Registration would, in the Issuer's good
faith judgment, contain an untrue statement of a material fact or omit to state
a material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading, and (ii) (a)
the Issuer determines in its good faith judgment that the disclosure of such
event at such time would


                                       15
<PAGE>

have a material adverse effect on the business, operations or prospects of the
Issuer or (b) the disclosure otherwise relates to a pending material business
transaction that has not yet been publicly disclosed.

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

            (l) in the case of a Shelf Registration, enter into such agreements
(including underwriting agreements) and take all such other appropriate actions
as are reasonably requested in order to expedite or facilitate the registration
or the disposition of such Registrable Notes, and in such connection, (i) make
such representations and warranties to Holders of such Registrable Notes with
respect to the business of the Issuer and its subsidiaries as then conducted and
the Registration Statement, Prospectus and documents, if any, incorporated or
deemed to be incorporated by reference therein, in each case, as are customarily
made by issuers to underwriters in underwritten offerings, and confirm the same
if and when requested; (ii) obtain an opinion of counsel to the Issuer and
updates thereof in form and substance reasonably satisfactory to the Holders of
a majority in principal amount of the Registrable Notes being sold, addressed to
each selling Holder covering the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably
requested by such Holders; (iii) obtain "cold comfort" letters and updates
thereof from the independent certified public accountants of the Issuer (and, if
necessary, any other independent certified public accountants of any subsidiary
of the Issuer or of any business acquired by any of the Issuer for which
financial statements and financial data are, or are required to be, included in
the Registration Statement), addressed to the selling Holders of Registrable
Notes that satisfy the applicable requirements of Statement of Accounting
Standards No. 72, such letters to be in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
underwritten offerings and such other matters as reasonably requested by such
selling Holders; and (iv) if an underwriting agreement is entered into, the same
shall contain indemnification provisions and procedures no less favorable than
those set forth in Section 7 hereof (or such other provisions and procedures
acceptable to the Issuer and the Holders of a majority in aggregate principal
amount of Registrable Notes covered by such Registration with respect to all
parties to be indemnified pursuant to said Section including, without
limitation, such selling Holders). The above shall be done at each closing in
respect of the sale of Registrable Notes, or as and to the extent required
thereunder.

            (m) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer


                                       16
<PAGE>

who seeks to sell Exchange Notes during the Applicable Period, make available
for inspection by any selling Holder of such Registrable Notes being sold, or
each such Participating Broker-Dealer, as the case may be, any underwriter
participating in any such disposition of Registrable Notes, if any, and any
attorney, accountant or other agent retained by any such selling Holder or each
such Participating Broker-Dealer, as the case may be, or underwriter
(collectively, the "Inspectors"), at the offices where normally kept, during
regular business hours and upon reasonable notice, all financial and other
records, pertinent corporate documents and instruments of the Issuer and
subsidiaries of the Issuer (collectively, the "Records") as shall be reasonably
necessary to enable them to exercise any applicable due diligence
responsibilities, and cause the officers, directors and employees of the Issuer
and any of its subsidiaries to supply all information reasonably requested by
any such Inspector in connection with such Registration Statement and
Prospectus. Each Inspector shall agree in writing that it will keep the Records
confidential and that it will not disclose any of the Records that the Issuer
determines, in good faith, to be confidential and notify the Inspectors in
writing are confidential unless (i) the disclosure of such Records is necessary
to avoid or correct a material misstatement or material omission in such
Registration Statement or Prospectus, (ii) the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction, or (iii) the information in such Records has been made generally
available to the public; provided, however, that prior notice shall be provided
as soon as practicable to the Issuer of the potential disclosure of any
information by such Inspector pursuant to clauses (i) or (ii) of this sentence
to permit the Issuer to obtain a protective order (or waive the provisions of
this paragraph (m)) and that such Inspector shall take such actions as are
reasonably necessary to protect the confidentiality of such information (if
practicable) to the extent such action is otherwise not inconsistent with, an
impairment of or in derogation of the rights and interests of the Holder or any
Inspector.

            (n) Provide an indenture trustee for the Registrable Notes or the
Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Registrable Notes; and in connection
therewith, cooperate with the trustee under any such indenture and the Holders
of the Registrable Notes, to effect such changes to such indenture as may be
required for such indenture to be so qualified in accordance with the terms of
the TIA; and execute, and use their best efforts to cause such trustee to
execute, all documents as may be required to effect such changes, and all other
forms and documents required to be filed with the SEC to enable such indenture
to be so qualified in a timely manner.

            (o) Comply with all applicable rules and regulations of the SEC and
make generally available to their securityholders with regard to any applicable
Registration Statement, a consolidated earning statement satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or
any similar rule promulgated under the Securities


                                       17
<PAGE>

Act) no later than 45 days after the end of any twelve-month period (or 90 days
after the end of any 12-month period if such period is a fiscal year) (i)
commencing at the end of any fiscal quarter in which any Registrable Notes are
sold to underwriters in a firm commitment or best efforts underwritten offering
and (ii) if not sold to underwriters in such an offering, commencing on the
first day of the first fiscal quarter of the Issuer after the effective date of
a Registration Statement, which statements shall cover said 12-month periods.

            (p) Upon consummation of an Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Issuer addressed to the Trustee for the
benefit of all Holders of Registrable Notes participating in the Exchange Offer
or Private Exchange, as the case may be, that the Exchange Notes or Private
Exchange Notes as the case may be, and the related indenture constitute legal,
valid and binding obligations of the Issuer, enforceable against it in
accordance with their respective terms subject to customary exceptions and
qualifications.

            (q) If the Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Notes by Holders to the Issuer (or
to such other Person as directed by the Issuer) in exchange for the Exchange
Notes or the Private Exchange Notes, as the case may be, the Issuer shall mark,
or cause to be marked, on such Registrable Notes that such Registrable Notes are
being canceled in exchange for the Exchange Notes or the Private Exchange Notes,
as the case may be; provided that in no event shall such Registrable Notes be
marked as paid or otherwise satisfied.

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

            (s) Use its best efforts to take all other steps reasonably
necessary to effect the registration of the applicable Registrable Notes covered
by a Registration Statement contemplated hereby.

            The Issuer may require each seller of any Registrable Notes as to
which any registration is being effected to furnish to the Issuer such
information regarding such seller and the distribution of such Registrable Notes
as the Issuer may, from time to time, reasonably request. The Issuer may exclude
from such registration the Registrable Notes of any seller for so long as such
seller fails to furnish such information within a reasonable time after
receiving such request and in such event shall have no further obligation under
this Agreement (including without limitation the obligation under Section 4)
with respect to such seller or any subsequent holder of such Registrable Notes.
Each seller as to which any Shelf Registration is being effected agrees to
furnish promptly to the Issuer all information required to be disclosed in order
to make the information previously furnished to the Issuer by such


                                       18
<PAGE>

seller not materially misleading.

            If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Issuer, then such Holder shall
have the right to require (i) the insertion therein of language, in form and
substance reasonably satisfactory to such Holder, to the effect that the holding
by such Holder of such securities is not to be construed as a recommendation by
such Holder of the investment quality of the securities covered thereby and that
such holding does not imply that such Holder will assist in meeting any future
financial requirements of the Issuer, or (ii) in the event that such reference
to such Holder by name or otherwise is not required by the Securities Act or any
similar federal statute then in force, the deletion of the reference to such
Holder in any amendment or supplement to the applicable Registration Statement
filed or prepared subsequent to the time that such reference ceases to be
required.

            Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange
Notes, as the case may be, to be sold by such Participating Broker-Dealer, as
the case may be, that, upon actual receipt of any notice from the Issuer of the
happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv),
5(c)(v), or 5(c)(vi) hereof, such Holder or Participating Broker-Dealer, as the
case may be, will forthwith discontinue disposition of such Registrable Notes or
Exchange Notes, as the case may be, covered by such Registration Statement or
Prospectus until such Holder's or Participating Broker-Dealer's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 5(j)
hereof, or until it is advised in writing (the "Advice") by the Issuer that the
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto. In the event that the Issuer shall give any
such notice, the Applicable Period shall be extended by the number of days
during such periods from and including the date of the giving of such notice to
and including the date when each seller of Registrable Notes covered by such
Registration Statement or Exchange Notes to be sold by such Participating
Broker-Dealer, as the case may be, shall have received (x) the copies of the
supplemented or amended Prospectus contemplated by Section 5(j) hereof or (y)
the Advice.

            6. Registration Expenses.

            All fees and expenses incident to the performance of or compliance
with this Agreement by the Issuer (other than any underwriting discounts or
commissions) shall be borne by the Issuer whether or not the Exchange
Registration Statement or any Shelf Registration is filed or becomes effective
or the Exchange Offer is consummated, including, without limitation, (i) all
registration and filing fees (including, without limitation, (A) fees with
respect to filings required to be made with the NASD in connection with an
underwritten offering and (B) fees and expenses of compliance with state
securities or Blue Sky laws (including, without limitation, reasonable fees and
disbursements of counsel in connection


                                       19
<PAGE>

with Blue Sky qualifications of the Registrable Notes or Exchange Notes and
determination of the eligibility of the Registrable Notes or Exchange Notes for
investment under the laws of such jurisdictions (x) where the holders of
Registrable Notes or Exchange Notes, as the case may be, are located, or (y) as
provided in Section 5(h) hereof, in the case of Registrable Notes or Exchange
Notes, as the case may be, to be sold by a Participating Broker-Dealer during
the Applicable Period)), (ii) printing expenses, including, without limitation,
expenses of printing certificates for Registrable Notes or Exchange Notes in a
form eligible for deposit with The Depository Trust Company and of printing
prospectuses if the printing of prospectuses is requested by the managing
underwriter or underwriters, if any, by the Holders of a majority in aggregate
principal amount of the Registrable Notes included in any Registration Statement
or to be sold by any Participating Broker-Dealer, as the case may be, (iii)
messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Issuer and fees and disbursements of one special counsel for all
of the sellers of each of the Registrable Notes (exclusive of any counsel
retained pursuant to Section 7 hereof), (v) fees and disbursements of all
independent certified public accountants referred to in Section 5(l)(iii) hereof
(including, without limitation, the expenses of any special audit and "cold
comfort" letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Issuer desires such insurance, (vii) fees and
expenses of all other Persons retained by the Issuer, (viii) internal expenses
of the Issuer (including, without limitation, all salaries and expenses of
officers and employees of the Issuer performing legal or accounting duties),
(ix) the expense of any annual audit, (x) any fees and expenses incurred in
connection with the listing of the securities to be registered on any securities
exchange, and the obtaining of a rating of the securities, in each case, if
applicable, and (xi) the expenses relating to printing, word processing and
distributing all Registration Statements, underwriting agreements, indentures
and any other documents necessary in order to comply with this Agreement.

            7. Indemnification and Contribution.

            (a) The Issuer agrees to indemnify and hold harmless each Holder of
the Registrable Notes and each Participating Broker-Dealer selling the Exchange
Notes during the Applicable Period, the affiliates, officers and directors of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "Participant"), from and against any and all losses,
claims, damages, judgments, liabilities and expenses (including, without
limitation, the legal fees and other expenses actually incurred in connection
with any suit, action or proceeding or any claim asserted) caused by, arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if the Issuer shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by,
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements


                                       20
<PAGE>

therein, in the case of the Prospectus in the light of the circumstances under
which they were made, not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
information relating to any Participant furnished to the Issuer in writing by
such Participant expressly for use therein and with respect to any preliminary
Prospectus, to the extent that any such loss, claim, damage or liability arises
solely from the fact that any Participant sold Registrable Notes or Exchange
Notes to a person to whom there was not sent or given a copy of the Prospectus
(as amended or supplemented) at or prior to the written confirmation of such
sale if the Issuer shall have previously furnished copies thereof to the
Participant in accordance herewith and the Prospectus (as amended or
supplemented) would have corrected any such untrue statement or omission.

            (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Issuer, the affiliates, officers and directors of the
Issuer and each Person who controls the Issuer within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act to the same extent (but
on a several, and not joint, basis) as the foregoing indemnity from the Issuer
to each Participant, but only with reference to information relating to such
Participant furnished to the Issuer in writing by or on behalf of such
Participant expressly for use in any Registration Statement or Prospectus, any
amendment or supplement thereto, or any preliminary prospectus. The liability of
any Participant under this paragraph shall in no event exceed the proceeds
received by such Participant from sales of Registrable Notes or Exchange Notes
giving rise to such obligations.

            (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such Person (the "Indemnified Person") shall promptly
notify the Persons against whom such indemnity may be sought (the "Indemnifying
Persons") in writing, and the Indemnifying Persons, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Persons may reasonably designate in such proceeding and shall pay
the fees and expenses actually incurred by such counsel related to such
proceeding; provided, however, that the failure to so notify the Indemnifying
Persons will not relieve it from any liability under paragraph (a) or (b) above
unless and to the extent such failure results in the forfeiture by the
Indemnifying Person of substantial rights and defenses and the Indemnifying
Person was not otherwise aware of such action or claim. In any such proceeding,
any Indemnified Person shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such Indemnified
Person unless (i) the Indemnifying Persons and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed
within a reasonable period of time to retain counsel reasonably satisfactory to
the Indemnified Person or (iii) the named parties in any such proceeding


                                       21
<PAGE>

(including any impleaded parties) include both any Indemnifying Person and the
Indemnified Person or any affiliate thereof and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Persons shall
not, in connection with such proceeding or separate but substantially similar
related proceedings in the same jurisdiction arising out of the same general
allegations, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed promptly as they are incurred. Any
such separate firm for the Participants and such control Persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Notes and Exchange Notes sold by all such Participants and shall
be reasonably acceptable to the Issuer, and any such separate firm for the
Issuer, their affiliates, officers, directors, representatives, employees and
agents and such control Persons of the Issuer shall be designated in writing by
the Issuer and shall be reasonably acceptable to the Holders.

            The Indemnifying Persons shall not be liable for any settlement of
any proceeding effected without its prior written consent (which consent shall
not be unreasonably withheld or delayed), but if settled with such consent or if
there be a final non-appealable judgment for the plaintiff for which the
Indemnified Person is entitled to indemnification pursuant to this Agreement,
each of the Indemnifying Persons agrees to indemnify and hold harmless each
Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Person shall, without the prior written
consent of the Indemnified Persons (which consent shall not be unreasonably
withheld or delayed), effect any settlement or compromise of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party, or indemnity could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional written
release of such Indemnified Person, in form and substance reasonably
satisfactory to such Indemnified Person, from all liability on claims that are
the subject matter of such proceeding and (B) does not include any statement as
to an admission of fault, culpability or failure to act by or on behalf of such
Indemnified Person.

            (d) If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as


                                       22
<PAGE>

well as any other relevant equitable considerations. The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Issuer
on the one hand or such Participant or such other Indemnified Person, as the
case may be, on the other, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission,
and any other equitable considerations appropriate in the circumstances.

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

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

            8. Rules 144 and 144A.

            The Issuer covenants and agrees that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the SEC thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and,
if at any time the Issuer is not required to file such reports, the Issuer will,
upon the request of any Holder or beneficial owner of Registrable Notes, make
available such information necessary to permit sales pursuant to Rule 144A under
the Securities Act. The Issuer further covenants and agrees, for so long as any
Registrable Notes remain outstanding that it will take such further action as
any Holder of Registrable Notes may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Notes
without registration under the Securities Act within the limitation of the


                                       23
<PAGE>

exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act,
as such Rules may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC.

            9. Miscellaneous.

            (a) No Inconsistent Agreements. The Issuer has not, as of the date
hereof, and the Issuer shall not, after the date of this Agreement, enter into
any agreement with respect to any of their securities that is inconsistent with
the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Issuer's other issued and outstanding
securities under any such agreements. The Issuer will not enter into any
agreement with respect to any of its securities which will grant to any Person
piggy-back registration rights with respect to any Registration Statement.

            (b) Adjustments Affecting Registrable Securities. The Issuer shall
not, directly or indirectly, take any action with respect to the Registrable
Notes that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

            (c) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (I) the Issuer and (II)(A) the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Notes and (B) in
circumstances that would adversely affect the Participating Broker-Dealers, the
Participating Broker-Dealers holding not less than a majority in aggregate
principal amount or liquidation preference, as the case may be, of the Exchange
Notes held by all Participating Broker-Dealers; provided, however, that Section
7 and this Section 10(c) may not be amended, modified or supplemented without
the prior written consent of each Holder and each Participating Broker-Dealer
(including any person who was a Holder or Participating Broker-Dealer of
Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to
any Registration Statement) affected by any such amendment, modification or
supplement. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders of Registrable Notes whose securities are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect,
impair, limit or compromise the rights of other Holders of Registrable Notes may
be given by Holders of at least a majority in aggregate principal amount of the
Registrable Notes being sold pursuant to such Registration Statement.

            (d) Notices. All notices and other communications (including,
without


                                       24

FOR IMMEDIATE RELEASE

   FLAG TELECOM HOLDINGS LIMITED CLOSES HIGH YIELD OFFERING WITH SALE OF $588
                        MILLION IN 10-YEAR SENIOR NOTES

London, 17 March 2000 - FLAG Telecom (Nasdaq: FTHL; LSE: FTL), a leading global
carriers' carrier, today announced the company has successfully sold $300
million of 10-year senior notes and 300 million Euro ($288 million) of 10-year
senior notes, at a rate of 11.625% for both currencies. The notes were offered
to qualified institutional buyers in the United States within the meaning of the
Securities Act of 1933 and to non-United States persons overseas pursuant to
Regulation S under the Securities Act. The notes have not been registered under
the Securities Act and may not be offered or sold in the United States absent
registration or an applicable exemption from registration requirements. FLAG
Telecom owns and operates the FLAG (Fiberoptic Link Around the Globe)
Europe-Asia cable system, stretching 28,000 km from the UK to Japan, and
provides an innovative range of products and services to the international
carrier community and Internet Service Providers. The company's latest venture,
FLAG Atlantic-1 (FA-1), now under construction, will provide fully protected
services between London, Paris and New York and extend the network to 42,500
route kilometres. The FA-1 cable project is on track and is expected to enter
commercial service during March 2001.

Ed McCormack, COO and CFO, FLAG Telecom, said: "We are very pleased with the
results of this offering. Following the recent IPO of the company and this
additional fundraising we are now set to accelerate the development of
innovative products and services and extend the reach of the FLAG Telecom
network."

The FLAG Europe-Asia cable, with 16 operational landing points in 13 countries,
directly connects landings in Japan (2) and the UK, via the Atlantic Ocean,
Mediterranean Sea, Red Sea, Indian Ocean, the South China Sea, and the Pacific
Ocean. The cable is the longest private cable system ever built and provides
high-capacity digital services to international carriers, resellers, and ISPs.

The FLAG Europe-Asia cable, along what is considered the most difficult route of
any cable system in the world, took 27 months and required approximately 4,000
permits to install. It spans many of the world's fastest growing economies and
offers direct connectivity to over 75 percent of the world's population. Built
at a cost of $1.6bn, the cable is designed to meet the growing demand for
international communications services, providing carriers with a world-class

<PAGE>

broadband superhighway. Currently the company has over 90 telecommunications
operators as customers, including most of the world's top carriers.

FLAG Atlantic-1, the company's latest venture now under construction, is
designed to be the world's first terabit/s transoceanic dual cable system
offering fully protected services between Paris, London and New York. The system
will be a triple-ring, dual cable system, connecting the East Coast of the
United States, with nodes in the heart of New York to two landings in Europe -
one in Brittany, France and the other in Cornwall, UK, with city nodes in Paris
and London. Customers will be able to add traffic either at the shore landing
stations or the city nodes. The planned three self-healing rings are designed to
provide secure end to end circuits to most of the major world business centres.
FA-1 will connect to the FLAG Europe-Asia cable system in Cornwall, UK.

FLAG Telecom offers terrestrial connections between FLAG Telecom's landing
stations in the United Kingdom and Spain to the city centres of London and
Madrid, and intra-European connections to major European metropolitan areas.
This capacity is provided through arrangements with key European bandwidth
providers, including iaxis.

The single FLAG network operations centre (FNOC) is located in the central time
zone of the Europe-Asia route, at Fujairah in the United Arab Emirates. The FNOC
manages all maintenance activity, performance monitoring and activates capacity
on demand. With the addition of FLAG Atlantic-1, which will be built and
operated as a 50:50 joint venture with GTS, the network is expected to extend to
over 42,500 route kilometers, enough to encircle the globe.
