     satisfactory, showing that at the date therein mentioned such Person had on

     bearing a later date issued in respect of the same Bearer Security is
     produced, or (2) such Bearer Security is produced to the Trustee by some
     other person, or (3) such Bearer Security is surrendered in exchange for a

     of the matters referred to in this Section.

          (f)    Any request, demand, authorization, direction, notice, consent,
     waiver or other Act of the Holder of any Debt Security shall bind every
     future holder of the same Debt Security and the Holder of every Debt
     Security issued upon the registration of transfer thereof or in exchange
     therefor or in lieu thereof in respect of anything done, suffered or
     omitted by the Trustee or the Company in reliance thereon, whether or not
     notation of such action is made upon such Debt Security.

          (g)    For purposes of determining the principal amount of Outstanding
     Debt Securities of any series the Holders of which are required, requested
     or permitted to give any request, demand, authorization, direction, notice,
     consent, waiver or take any other Act under this Indenture, (i) each
     Original Issue Discount Security shall be deemed to have the principal
     amount determined by the Trustee that could be declared to be due and
     payable pursuant to the terms of such Original Issue Discount Security as
     of the date there is delivered to the Trustee and, where it is hereby
     expressly required, to the Company, such Act by Holders of the required
     aggregate principal amount of the Outstanding Debt Securities of such
     series and (ii) each Debt Security denominated in a Foreign Currency or
     composite currency shall be deemed to have the principal amount determined
     by the Exchange Rate Agent by converting the principal amount of such Debt
     Security in the currency in which such Debt Security is denominated into
     Dollars at the Exchange Rate as of the date such Act is delivered to the
     Trustee and, where it is hereby expressly required, to the Company, by
     Holders of the required aggregate principal amount of the Outstanding Debt
     Securities of such series.

          (h)    The Company may set any day as a record date for the purpose of
     determining the Holders of Outstanding Debt Securities of any series
     entitled to give, make or take any request, demand, authorization,
     direction, notice, consent, waiver or other action provided or permitted by
     this Indenture to be given, made or taken by Holders of Debt Securities of
     such series, provided that the Company may not set a record date for, and
     the provisions of this paragraph shall not apply with respect to, the
     giving or making of any notice, declaration, request or direction referred
     to in the next paragraph. If any record date is set pursuant to this
     paragraph, the Holders of Outstanding Debt Securities of the relevant
     series on such record date, and no other Holders, shall be entitled to take
     the relevant action, whether or not such Holders remain Holders after such
     record date; provided that no such action shall be effective hereunder
     unless taken on or prior to the applicable Expiration Date (as defined
     below) by Holders of the requisite principal amount of Outstanding Debt
     Securities of such series on such record date. Nothing in this paragraph
     shall be construed to prevent the Company from setting a new record date
     for any action for which a record date has previously been set pursuant to
     this paragraph (whereupon the record date previously set shall
     automatically and with no action by any Person be cancelled and of no
     effect), and nothing in this paragraph shall be construed to render
     ineffective any action taken by Holders of the requisite principal amount
     of Outstanding Debt Securities of the relevant series on the date such
     action is taken. Promptly after any record date is set pursuant to this
     paragraph, the Company, at its own expense, shall cause notice of such
     record date, the proposed action by Holders and the applicable Expiration
     Date to be given to the Trustee in writing and to each Holder of Debt
     Securities of the relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Debt Securities of any series entitled to join in the
giving or making of (i) any notice of an Event of Default, (ii) any declaration
of acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2), or (iv) any direction referred to in
Section 512, in each case with respect to Debt Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding Debt
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding Debt
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Debt Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of Debt
Securities of the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may

                                      -11-
<Page>

change the Expiration Date to any earlier or later day; provided that no such
change shall be effective unless notice of the proposed new Expiration Date is
given to the other party hereto in writing, and to each Holder of Debt
Securities of the relevant series in the manner set forth in Section 106, on or
prior to the existing Expiration Date. If an Expiration Date is not designated
with respect to any record date set pursuant to this Section, the party hereto
which set such record date shall be deemed to have initially designated the
180th day after such record date as the Expiration Date with respect thereto,
subject to its right to change the Expiration Date as provided in this
paragraph.

     Section 105.   NOTICES, ETC., TO TRUSTEE AND COMPANY.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of Holders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with,

          (1)    the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided),
     if made, given, furnished or filed in writing (which may be via original or
     facsimile, with original to follow promptly thereafter) to or with the
     Trustee at its Corporate Trust Office, or

          (2)    the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to the attention of its Secretary at the address of its principal
     office specified in the first paragraph of this instrument or at any other
     address previously furnished in writing to the Trustee by the Company.

     Section 106.   NOTICE TO HOLDERS; WAIVER.

     Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of any event, (1) such notice shall be
sufficiently given to Holders of Registered Securities if in writing and mailed,
first-class postage prepaid, to each Holder of a Registered Security affected by
such event, at such Holder's address as it appears in the Security Register, not
later than the latest date, and not earlier than the earliest date, prescribed
for the giving of such notice; and (2) such notice shall be sufficiently given
to Holders of Bearer Securities by publication thereof in an Authorized
Newspaper in The City of New York and, if the Debt Securities of such series are
then listed on The International Stock Exchange of the United Kingdom and the
Republic of Ireland and such stock exchange shall so require, in London, and, if
the Debt Securities of such series are then listed on the Luxembourg Stock
Exchange and such stock exchange shall so require, in Luxembourg and, if the
Debt Securities of such series are then listed on any other stock exchange
outside the United States and such stock exchange shall so require, in any other
required city outside the United States or, if not practicable, in Europe on a
Business Day at least twice, the first such publication to be not later than the
latest date and not earlier than the earliest date prescribed for the giving of
such notice.

     In case, by reason of the suspension of or irregularities in regular mail
service or for any other reason, it shall be impossible or impracticable to mail
notice of any event to Holders of Registered Securities when said notice is
required to be given pursuant to any provision of this

                                      -12-
<Page>

Indenture or of the Debt Securities, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice. In any case where notice to Holders of Registered Securities is
to be given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder of a Registered Security shall
affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice by publication to Holders
of Bearer Securities given as provided above.

     In case, by reason of the suspension of publication of any Authorized
Newspaper, or by reason of any other cause, it shall be impossible or
impracticable to make publication of any notice to Holders of Bearer Securities
as provided above, then such method of publication or notification as shall be
made with the approval of the Trustee shall constitute a sufficient publication
of such notice. Neither failure to give notice by publication to Holders of
Bearer Securities as provided above, nor any defect in any notice so published,
shall affect the sufficiency of any notice mailed to Holders of Registered
Securities as provided above.

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

     Any request, demand, authorization, direction, notice, consent, election,
waiver or other Act required or permitted under this Indenture shall be in the
English language, except that any published notice may be in an official
language of the country of publication.

     Section 107.   CONFLICT WITH TRUST INDENTURE ACT.

     If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control.

     Section 108.   EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

     Section 109.   SUCCESSORS AND ASSIGNS.

     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

     Section 110.   SEPARABILITY CLAUSE.

     In case any provision in this Indenture or in the Debt Securities or any
coupons 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 111.   BENEFITS OF INDENTURE.

<Page>

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

     Section 112.   GOVERNING LAW; WAIVER OF JURY TRIAL..

     This Indenture and the Debt Securities and any coupons shall be governed by
and construed in accordance with the laws of the State of New York. Each of the
Company and the Trustee hereby irrevocably waives, to the fullest extent
permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Indenture, the Debt Securities or
the transaction contemplated hereby.

     Section 113.   LEGAL HOLIDAYS.

     In any case where any Interest Payment Date, Redemption Date, Repayment
Date or Stated Maturity of any Debt Security shall not be a Business Day at any
Place of Payment, then (notwithstanding any other provision of this Indenture or
of the Debt Securities or any coupons) payment of interest or principal (and
premium, if any) need not be made at such Place of Payment on such date, but may
be made on the next succeeding Business Day at such Place of Payment with the
same force and effect as if made on the Interest Payment Date, Redemption Date,
Repayment Date or at the Stated Maturity, and no interest shall accrue on the
amount so payable for the period from and after such Interest Payment Date,
Redemption Date, Repayment Date or Stated Maturity, as the case may be.

     Section 114.   EXEMPTION FROM INDIVIDUAL LIABILITY.

     No recourse under or upon any obligation, covenant or agreement of this
Indenture, or of any Debt Security or any coupon, or for any claim based thereon
or otherwise in respect thereof, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor corporation, either directly or through the Company,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations of the Company, and that no such personal liability
whatever shall attach to, or is or shall be incurred by, the incorporators,
stockholders, officers or directors, as such, of the Company or of any successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debt Securities or any coupon or
implied therefrom; and that any and all such personal liability, either at
common law or in equity or by constitution or statute, of, and any and all such
rights and claims against, every such incorporator, stockholder, officer or
director, as such, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debt Securities or any coupon or
implied therefrom, are hereby expressly waived and released as a condition of,
and as a consideration for, the execution of this Indenture and the issue of
such Debt Securities.

                               DEBT SECURITY FORMS

     Section 201.   FORMS GENERALLY.

     The Registered Securities, if any, and the Bearer Securities and related
coupons, if any, of each series shall be in substantially the form (including
temporary or permanent global form) as shall be established in or pursuant to a
Board Resolution or in one or more indentures supplemental hereto, in each case
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture, and may have such letters,

thereon, as may be required to comply with the rules of any securities exchange,
or as may, consistently herewith, be determined by the officers executing such
Debt Securities or coupons, as evidenced by their signatures on the Debt

     The definitive Debt Securities and coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any

     Section 203.   DEBT SECURITIES IN GLOBAL FORM.

     If Debt Securities of a series are issuable in whole or in part in global
form, as specified as contemplated by Section 301, then, notwithstanding clause
(10) of Section 301 and the provisions of Section 302, such Global Security
shall represent such of the outstanding Debt Securities of such series as shall
be specified therein and may provide that it shall represent the aggregate
amount of Outstanding Debt Securities from time to time endorsed thereon and
that the aggregate amount of Outstanding Debt Securities represented thereby may
from time to time be reduced to reflect exchanges. Any endorsement of a Global
Security to reflect the amount, or any increase or decrease in the amount, of
Outstanding Debt Securities represented thereby shall be made in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 303
or Section 304.

     The provisions of the last sentence of Section 303(g) shall apply to any
Debt Securities represented by a Debt Security in global form if such Debt
Security was never issued and sold by the Company and the Company delivers to
the Trustee the Debt Security in global form together with written instructions
(which need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel) with respect to the reduction in the principal amount of
Debt Securities represented thereby, together with the written statement
contemplated by the last sentence of Section 303(g).

     Global Securities may be issued in either registered or bearer form and in
permanent form or, in the case of Bearer Securities, either temporary or
permanent form.

Officers' Certificate setting forth the terms of the series.

     Section 302.   DENOMINATIONS.

     Debt Securities of each series shall be issuable in such form and
denominations as shall be specified in the form of Debt Security for such series
approved or established pursuant to Section 201 or in the Officers' Certificate
delivered pursuant to Section 301. In the absence of any specification with
respect to the Debt Securities of any series, the Registered Securities of

                                      -19-
<Page>

such series, if any, shall be issuable in denominations of $1,000 and any
integral multiple thereof and the Bearer Securities of such series, if any,
shall be issuable in the denominations of $5,000.

     Section 303.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

          (a)    The Debt Securities shall be executed on behalf of the Company
     by its Chairman of the Board, a Vice Chairman of the Board, the President,
     a Vice President, the Treasurer or one of its Assistant Treasurers and by
     its Secretary or one of its Assistant Secretaries. The signature of any of
     these officers on the Debt Securities may be manual or facsimile. Coupons
     shall bear the facsimile signature of an authorized officer of the Company.

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

          (b)    At any time and from time to time after the execution and
     delivery of this Indenture, Debt Securities of any series may be executed
     by the Company and delivered to the Trustee for authentication, and, except
     as otherwise provided in this Article Three, shall thereupon be
     authenticated and delivered by the Trustee upon Company Order, without any
     further action by the Company; provided, however, that, in connection with
     its original issuance, a Bearer Security may be delivered only outside the
     United States and, except in the case of a temporary Global Security, only
     if the Company or its agent shall have received the certification required
     pursuant to Sections 304(b)(iii) and (iv), unless such certification shall
     have been provided earlier pursuant to Section 304(b)(v) hereof, and only
     if the Company has no reason to know that such certification is false.

          To the extent authorized in or pursuant to a Board Resolution and set
     forth in an Officers' Certificate, or established in one or more indentures
     supplemental hereto, such written Company Order may be given by any one
     officer or employee of the Company, may be electronically transmitted, and
     may provide instructions as to registration of holders, principal amounts,
     rates of interest, maturity dates and other matters contemplated by such
     Board Resolution and Officers' Certificate or supplemental indenture to be
     so instructed in respect thereof. Before authorizing and delivering the
     first Debt Securities of any series (and upon request of the Trustee
     thereafter), the Company shall deliver to the Trustee (i) the certificates
     called for under Sections 201 and 301 hereof and (ii) an Opinion of Counsel
     described in the next sentence.

          In authenticating such Debt Securities, and accepting the additional
     responsibilities under this Indenture in relation to any such Debt
     Securities, the Trustee shall be entitled to receive, prior to the initial
     authentication of such Debt Securities, and (subject to Section 601) shall
     be fully protected in relying upon:

                                      -20-
<Page>

          (i)    a Board Resolution relating thereto and, if applicable, an
     appropriate record of any action taken pursuant to such resolution
     certified by the Secretary or an Assistant Secretary of the Company;

          (ii)   an executed supplemental indenture, if any, relating thereto;

          (iii)  an Officers' Certificate setting forth the form and terms of
     the Debt Securities of such series and coupons, if any, pursuant to
     Sections 201 and 301 and stating that all conditions precedent provided for
     in this Indenture relating to the issuance of such Debt Securities have
     been complied with; and

          (iv)   an Opinion of Counsel stating

          (A)    that the form of such Debt Securities and coupons, if any, has
     been established in or pursuant to a Board Resolution or by a supplemental
     indenture as permitted by Section 201 in conformity with the provisions of
     this Indenture;

          (B)    that the terms of such Debt Securities and coupons, if any,
     have been established in or pursuant to a Board Resolution or by a
     supplemental indenture as permitted by Section 301 in conformity with the
     provisions of this Indenture; and

          (C)    that such Debt Securities and coupons, if any, when
     authenticated and delivered by the Trustee and issued by the Company in the
     manner and subject to any conditions specified in such Opinion of Counsel,
     will constitute valid and binding obligations of the Company, enforceable
     in accordance with their terms, subject, as to enforcement of remedies, to
     applicable bankruptcy, reorganization, insolvency, moratorium or other laws
     affecting creditors' rights generally and the application of general
     principles of equity and except further as enforcement thereof may be
     limited by (i) requirements that a claim with respect to any Debt
     Securities denominated other than in Dollars (or a Foreign Currency or
     currency unit judgment in respect of such claim) be converted into Dollars
     at a rate of exchange prevailing on a date determined pursuant to
     applicable law or (ii) governmental authority to limit, delay or prohibit
     the making of payments in Foreign Currencies or currency units or payments
     outside the United States.

          (c)    If the Company shall establish pursuant to Section 301 that the
     Debt Securities of a series are to be issued in whole or in part in the
     form of one or more Global Securities, then the Company shall execute and
     the Trustee shall, in accordance with this Section and the Company Order
     with respect to such series, authenticate and deliver one or more Global
     Securities in permanent or temporary form that (i) shall represent and
     shall be denominated in an aggregate amount equal to the aggregate
     principal amount of the Outstanding Debt Securities of such series to be
     represented by one or more Global Securities, (ii) shall be registered in
     the name of the Depositary for such Global Security or Securities or the
     nominee of such Depositary and (iii) shall be delivered by the Trustee to
     such Depositary or pursuant to such Depositary's instructions.

          (d)    The Trustee shall have the right to decline to authenticate and
     deliver any Debt Securities under this Section 303 if the issuance of such
     Debt Securities will adversely affect the Trustee's own rights, duties or
     immunities under the Debt Securities

                                      -21-
<Page>

     and this Indenture or otherwise in a manner which is not reasonably
     acceptable to the Trustee.

          (e)    If all the Debt Securities of any series are not to be issued
     at onetime, it shall not be necessary to deliver an Opinion of Counsel at
     the time of issuance of each Debt Security, but such Opinion of Counsel,
     with appropriate modifications, may instead be delivered at or prior to the
     time of the first issuance of Debt Securities of such series.

          (f)    Each Registered Security shall be dated the date of its
     authentication. Each Bearer Security shall be dated as of the date
     specified as contemplated by Section 301.

          (g)    No Debt Security or coupon attached thereto shall be entitled
     to any benefit under this Indenture or be valid or obligatory for any
     purpose, unless there appears on such Debt Security a certificate of
     authentication substantially in the form provided for herein executed by
     the Trustee, and such certificate upon any Debt Security shall be
     conclusive evidence, and the only evidence, that such Debt Security has
     been duly authenticated and delivered hereunder. Except as permitted by
     Section 306, the Trustee shall not authenticate and deliver any Bearer
     Security unless all appurtenant coupons for interest then matured have been
     detached and cancelled. Notwithstanding the foregoing, if any Debt Security
     or portion thereof shall have been duly authenticated and delivered
     hereunder but never issued and sold by the Company, and the Company shall
     deliver such Debt Security to the Trustee for cancellation as provided in
     Section 309 together with a written statement (which need not comply with
     Section 102 and need not be accompanied by an Opinion of Counsel) stating
     that such Debt Security or portion thereof has never been issued and sold
     by the Company, for all purposes of this Indenture such Debt Security shall
     be deemed never to have been authenticated and delivered hereunder and
     shall never be entitled to the benefits of this Indenture.

          (h)    Each Depositary designated pursuant to Section 301 for a Global
     Security in registered form must, at the time of its designation and at all
     times while it serves as Depositary, be a clearing agency registered under
     the Securities Exchange Act of 1934 and any other applicable statute or
     regulation.

     Section 304.   TEMPORARY DEBT SECURITIES.

          (a)    Pending the preparation of definitive Debt Securities of any
     series, the Company may execute, and upon receipt of documents required by
     Sections 301 and 303, together with a Company Order, the Trustee shall
     authenticate and deliver, temporary Debt Securities which are printed,
     typewritten or otherwise produced, in any denomination, substantially of
     the tenor and terms of the definitive Debt Securities in lieu of which they
     are issued in registered form or, if authorized, in bearer form with one or
     more coupons or without coupons, and with such appropriate insertions,
     omissions, substitutions and other variations as the officers executing
     such Debt Securities may determine, as evidenced by their signatures on
     such Debt Securities. In the case of Debt Securities of any series issuable
     as Bearer Securities, such temporary Debt Securities may be in global form,
     representing all or any part of the Outstanding Debt Securities of such
     series.

                                      -22-
<Page>

          (b)    Unless otherwise provided pursuant to Section 301:

          (i)    Except in the case of temporary Debt Securities in global form,
     if temporary Debt Securities of any series are issued, the Company will
     cause definitive Debt Securities of such series to be prepared without
     unreasonable delay. After the preparation of definitive Debt Securities of
     such series, the related temporary Debt Securities shall be exchangeable
     for such definitive Debt Securities upon surrender of the temporary Debt
     Securities of such series at the office or agency of the Company in the
     Place of Payment for such series, without charge to the Holder. Upon
     surrender for cancellation of any one or more temporary Debt Securities of
     any series (accompanied, if applicable, by all unmatured coupons and all
     matured coupons in default appertaining thereto), the Company shall execute
     and the Trustee shall authenticate and deliver in exchange therefor a like
     principal amount of definitive Debt Securities of the same series of like
     tenor and terms and of authorized denominations; provided, however, that no
     Bearer Security shall be delivered in exchange for a Registered Security;
     and provided, further, that a Bearer Security shall be delivered in
     exchange for a Bearer Security only in compliance with the conditions set
     forth in Section 305.

          (ii)   If Debt Securities of any series are issued in temporary global
     form, any such temporary Global Security shall, unless otherwise provided
     pursuant to Section 301, be delivered to the Depositary for credit to the
     respective accounts of the beneficial owners of such Debt Securities (or to
     such other accounts as they may direct).

          (iii)  Without unnecessary delay but in any event not later than the
     date specified in, or determined pursuant to the terms of, any such
     temporary Global Security (the "Global Exchange Date"), the Company shall
     deliver definitive Debt Securities to the Trustee or the agent appointed by
     the Company pursuant to Section 301 to effect the exchange of the temporary
     Global Security for definitive Debt Securities (the "Global Exchange
     Agent"), in an aggregate principal amount equal to the principal amount of
     such temporary Global Security, executed by the Company. On or after the
     Global Exchange Date, such temporary Global Security shall be surrendered
     by the Depositary to the Global Exchange Agent, to be exchanged, in whole
     or from time to time in part, for definitive Debt Securities without charge
     and the Trustee or the Global Exchange Agent, if authorized by the Trustee
     pursuant to Section 614, shall authenticate and deliver, in exchange for
     each portion of such temporary Global Security, an equal aggregate
     principal amount of definitive Debt Securities of the same series of
     authorized denominations and of like tenor and terms as the portion of such
     temporary Global Security to be exchanged. Upon any exchange of a part of
     such temporary Global Security for definitive Debt Securities, the portion
     of the principal amount and any interest thereon so exchanged shall be
     endorsed by the Global Exchange Agent on a schedule to such temporary
     Global Security, whereupon the principal amount and interest payable with
     respect to such temporary Global Security shall be reduced for all purposes
     by the amount so exchanged and endorsed. The definitive Debt Securities to
     be delivered in exchange for any such temporary Global Security shall be in
     bearer form, registered form, global registered form or global bearer form,
     or any combination thereof, as specified as contemplated by Section 301,
     and, if any combination thereof is so specified, as requested by the
     beneficial owner thereof; provided, however, that definitive Bearer

                                      -23-
<Page>

     Securities (including a definitive Global Bearer Security) shall be
     delivered in exchange for a portion of a temporary Global Security only in
     compliance with the requirements of Section 303.

          (iv)   The interest of a beneficial owner of Debt Securities of a
     series in a temporary Global Security shall be exchanged for definitive
     Debt Securities of the same series and of like tenor and terms following
     the Global Exchange Date upon request by the account holder and, in the
     case of the exchange of the temporary Global Security for definitive Bearer
     Securities (including a definitive Global Bearer Security), the account
     holder delivers a certificate in the form set forth in Exhibit A-1 and, if
     applicable, A-2 to this Indenture, dated no earlier than 15 days prior to
     the Global Exchange Date, copies of which certificate shall be available
     from the Global Exchange Agent, any authenticating agent appointed for such
     series of Debt Securities and each Paying Agent. Unless otherwise specified
     in such temporary Global Security, any such exchange shall be made free of
     charge to the beneficial owners of such temporary Global Security, except
     that a Person receiving definitive Debt Securities must bear the cost of
     insurance, postage, transportation and the like in the event that such
     Person does not take delivery of such definitive Debt Securities in person
     at the offices of Global Exchange Agent. Definitive Debt Securities in
     bearer form to be delivered in exchange for any portion of a temporary
     Global Security shall be delivered only outside the United States.

          (v)    Until exchanged in full as hereinabove provided, the temporary
     Debt Securities of any series shall in all respects be entitled to the same
     benefits under this Indenture as definitive Debt Securities of the same
     series and of like tenor and terms authenticated and delivered hereunder.

     Section 305.   REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company shall cause to be kept at one of the offices or agencies to be
maintained by the Company in accordance with the provisions of this Section 305
and Section 1002, with respect to the Debt Securities of each series which are
Registered Securities, a register (herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Registered Securities and of
transfers of Registered Securities. Pursuant to Section 301, the Company shall
appoint, with respect to Debt Securities of each series which are Registered
Securities, a "Security Registrar" for the purpose of registering such Debt
Securities and transfers and exchanges of such Debt Securities as herein
provided.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency of the Company maintained for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Registered
Securities of the same series of any authorized denomination or denominations,
of like tenor and terms and aggregate principal amount.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
form and denomination, of like tenor and terms and aggregate principal amount,
upon surrender of the Registered Securities to

                                      -24-
<Page>

be exchanged at such office or agency. Bearer Securities may not be delivered in
exchange for Registered Securities.

     At the option of the Holder, Registered Securities or Bearer Securities of
any series may be issued in exchange for Bearer Securities (except as otherwise
specified as contemplated by Section 301 with respect to a Bearer Security in
global form) of the same series, of any authorized denominations and of like
tenor and terms and aggregate principal amount, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security
of the same series and like tenor and terms after the close of business at such
office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be.

     Whenever any Debt Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debt
Securities which the Holder making the exchange is entitled to receive.

     If at any time the Depositary for the Debt Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Debt Securities of such series or if at any time the Depositary for the Debt
Securities of such series shall no longer be eligible under Section 303(h), the
Company shall appoint a successor Depositary with respect to the Debt Securities
of such series. If a successor Depositary for the Debt Securities of such series
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company's election pursuant
to Section 301(9) shall no longer be effective with respect to the Debt
Securities of such series and the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of definitive
Debt Securities of such series, will authenticate and deliver, Debt Securities
of such series in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing such series
in exchange for such Global Security or Securities. Neither the Trustee nor any
agent shall have any responsibility for any actions taken or not taken by the
Depositary.

                                      -25-
<Page>

     The Company may at any time and in its sole discretion determine that the
Debt Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by such Global Security or Securities.
In such event the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Debt Securities
of such series, will authenticate and deliver, Debt Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Security or Securities representing such series in exchange
for such Global Security or Securities.

     If specified by the Company pursuant to Section 301 with respect to a
series of Debt Securities, the Depositary for such series of Debt Securities may
surrender a Global Security for such series of Debt Securities in exchange in
whole or in part for Debt Securities of such series of like tenor and terms and
in definitive form on such terms as are acceptable to the Company and such
Depositary. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without charge to any Holder,

          (a)    to each Person specified by such Depositary a new Debt Security
     or Securities of the same series, of like tenor and terms and of any
     authorized denominations as requested by such person in aggregate principal
     amount equal to and in exchange for such Person's beneficial interest in
     the Global Security; and

          (b)    to such Depositary a new Global Security of like tenor and
     terms and in a denomination equal to the difference, if any, between the
     principal amount of the surrendered Global Security and the aggregate
     principal amount of Debt Securities delivered to Holders thereof.

     In any exchange provided for in any of the preceding three paragraphs, the
Company will execute and the Trustee will authenticate and deliver Debt
Securities (a) in definitive registered form in authorized denominations, if the
Debt Securities of such series are issuable as Registered Securities, (b) in
definitive bearer form in authorized denominations, with coupons attached, if
the Debt Securities of such series are issuable as Bearer Securities or (c) as
either Registered or Bearer Securities, as shall be specified by the beneficial
owner thereof, if the Debt Securities of such series are issuable in either
form; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary Global Security unless the Company or its agent
shall have received from the person entitled to receive the definitive Bearer
Security a certificate substantially in the form set forth in Exhibit A-1 and,
if applicable, A-2 hereto; and provided further that delivery of a Bearer
Security shall occur only outside the United States; and provided further that
no definitive Bearer Security will be issued if the Company has reason to know
that any such certificate is false.

     Upon the exchange of a Global Security for Debt Securities in definitive
form, such Global Security shall be cancelled by the Trustee. Registered
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Registered Securities to the persons in whose names such Debt
Securities are so registered. The Trustee shall deliver Bearer Securities issued
in exchange for a Global Security pursuant to this

                                      -26-
<Page>

Section to the persons, and in such authorized denominations, as the Depositary
for such Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee; provided, however, that
no definitive Bearer Security shall be delivered in exchange for a temporary
Global Security unless the Company or its agent shall have received from the
person entitled to receive the definitive Bearer Security a certificate
substantially in the form set forth in Exhibit A-1 and, if applicable, A-2
hereto; and provided further that delivery of a Bearer Security shall occur only
outside the United States; and provided further that no definitive Bearer
Security will be issued if the Company has reason to know that any such
certificate is false.

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

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

     No charge to any Holder shall be made for any registration of transfer or
exchange of Debt Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer, registration of transfer or exchange of Debt
Securities, other than exchanges expressly provided in this Indenture to be made
at the Company's own expense or without expense or without charge to the
Holders.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Debt Securities of any particular series to be redeemed for a period of
fifteen days preceding the first publication of the relevant notice of
redemption or, if Registered Securities are outstanding and there is no
publication, the mailing of the relevant notice of redemption of Debt Securities
of such series selected for redemption under Section 1103 and ending at the
close of business on the day of such mailing, or (ii) to register the transfer
of or exchange any Registered Security so selected for redemption in whole or in
part, except the unredeemed portion of such Registered Security being redeemed
in part, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of
like tenor and terms of that series, provided that such Registered Security
shall be simultaneously surrendered for redemption.

     Notwithstanding anything herein to the contrary, the exchange of Bearer
Securities into Registered Securities shall be subject to applicable laws and
regulations in effect at the time of exchange; neither the Company, the Trustee
nor the Security Registrar shall exchange any Bearer Securities into Registered
Securities if it has received an Opinion of Counsel that as a result of such
exchanges the Company would suffer adverse consequences under the United States
Federal income tax laws and regulations then in effect and the Company has
delivered to the Trustee a Company Order directing the Trustee not to make such
exchanges thereafter unless and

                                      -27-
<Page>

until the Trustee receives a subsequent Company Order to the contrary. The
Company shall deliver copies of such Company Orders to the Security Registrar.

     Section 306.   MUTILATED, DESTROYED, LOST AND STOLEN DEBT SECURITIES.

     If (i) any mutilated Debt Security or a Bearer Security with a mutilated
coupon appertaining to it is surrendered to a Paying Agent outside the United
States designated by the Company, or, in the case of any Registered Security, to
the Trustee, or (ii) the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Debt Security or coupon,
and there is delivered to the Company and the Trustee such security or indemnity
as may be required by them to save each of them harmless, then, in the absence
of notice to the Company and the Trustee that such Debt Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon its
written request the Trustee shall authenticate and deliver, in exchange for any
such mutilated Debt Security or Bearer Security with a mutilated coupon
appertaining to it or to which a destroyed, lost or stolen coupon appertains
(with all appurtenant coupons not destroyed, lost or stolen) or in lieu of any
such destroyed, lost or stolen Debt Security, a new Debt Security of like tenor
and terms and principal amount, bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
such destroyed, lost or stolen Debt Security or to the Debt Security to which
such destroyed, lost or stolen coupon appertains; provided, however, that any
such new Bearer Security will be delivered only in compliance with the
conditions set forth in Section 305.

     In case any such mutilated, destroyed, lost or stolen Debt Security or
coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Debt Security, pay such Debt Security
or coupon; provided, however, that payment of principal of (and premium, if any)
and any interest on Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an office or agency located outside the United
States; and provided, further, that, with respect to any such coupons, interest
represented thereby (but not any additional amounts payable as provided in
Section 1006), shall be payable only upon presentation and surrender of the
coupons appertaining thereto.

     Upon the issuance of any new Debt Security or coupons under this Section,
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 and printing expenses)
connected therewith.

     Every new Debt Security of any series, with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Debt Security,
or in exchange for a Bearer Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Debt Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and any such new Debt Security and coupons, if any, shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Debt Securities of that series and their coupons, if any,
duly issued hereunder.

                                      -28-

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

     Section 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Interest on any Registered Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Registered Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest. In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture. At the option of the Company, payment of interest on any Registered
Security may be made by check in the currency designated for such payment
pursuant to the terms of such Registered Security mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register or
by wire transfer to an account in such currency designated by such Person in
writing not later than fifteen days prior to the date of such payment.

     Any interest on any Registered Security of any series which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of his having
been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

          (1)    The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment, and at the same time the Company shall deposit with the
     Trustee an amount of money and/or Government Obligations the payments of
     principal and interest on which when due (and without reinvestment) will
     provide money in such amounts as will (together with any money irrevocably
     deposited in trust with the Trustee, without investment) be 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 and/or Government
     Obligations when deposited to be held in trust for the benefit of the
     Persons entitled to such Defaulted Interest as in this Clause provided.
     Thereupon the Trustee shall fix a Special Record Date for the payment of
     such Defaulted Interest which shall be not more than 15 days and not less
     than 10 days prior to the date of the proposed payment and not less than 10
     days after the receipt by the Trustee of the notice of the proposed
     payment. The Trustee shall

                                      -29-
<Page>

     promptly notify the Company of such Special Record Date. Unless the Trustee
     is acting as the Security Registrar, promptly after such Special Record
     Date, the Company shall furnish the Trustee with a list, or shall make
     arrangements satisfactory to the Trustee with respect thereto, of the names
     and addresses of, and principal amounts of Registered Securities of such
     series held by, the Holders appearing on the Security Register at the close
     of business on such Special Record Date. In the name and at the expense of
     the Company, the Trustee shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder of Registered Securities of
     such series at his address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been mailed as aforesaid, such Defaulted Interest shall be paid to
     the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following Clause (2). In case a Bearer Security of any
     series is surrendered at the office or agency in a Place of Payment for
     such series in exchange for a Registered Security of such series after the
     close of business at such office or agency on any Special Record Date and
     before the opening of business at such office or agency on the related
     proposed date for payment of Defaulted Interest, such Bearer Security shall
     be surrendered without the coupon relating to such proposed date of payment
     and Defaulted Interest will not be payable on such proposed date of payment
     in respect of the Registered Security issued in exchange for such Bearer
     Security, but will be payable only to the Holder of such coupon when due in
     accordance with the provisions of this Indenture.

          (2)    The Company may make payment of any Defaulted Interest on the
     Registered Securities of any series in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which the
     Registered Securities may be listed, and upon such notice as may be
     required by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this Clause, such manner of
     payment shall be deemed practicable by the Trustee.

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

     Subject to the limitations set forth in Section 1002, the Holder of any
coupon appertaining to a Bearer Security shall be entitled to receive the
interest payable on such coupon upon presentation and surrender of such coupon
on or after the Interest Payment Date of such coupon at an office or agency
maintained for such purpose pursuant to Section 1002.

     Section 308.   PERSONS DEEMED OWNERS.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or of the
Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Registered Security for

                                      -30-
<Page>

the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 307) interest on such Registered Security and for all other
purposes whatsoever, whether or not such Registered Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security and the bearer of any coupon as the
absolute owner of such Bearer Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Bearer Security or coupon be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     Section 309.   CANCELLATION.

     Unless otherwise provided with respect to a series of Debt Securities, all
Debt Securities and coupons surrendered for payment, redemption, repayment,
transfer, exchange or credit against any sinking fund payment pursuant to this
Indenture shall, if surrendered to the Company or any agent of the Company, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Debt Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Debt Securities so delivered shall be
promptly cancelled by the Trustee. No Debt Securities shall be authenticated in
lieu of or in exchange for any Debt Securities cancelled as provided in this
Section, except as expressly permitted by this Indenture. All cancelled Debt
Securities and coupons held by the Trustee shall be disposed of by the Trustee
in accordance with customary procedures.

     Section 310.   COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 301 for Debt
Securities of any series, interest on the Debt Securities of each series shall
be computed on the basis of a 360-day year of twelve 30-day months.

     Section 311.   CERTIFICATION BY A PERSON ENTITLED TO DELIVERY OF A BEARER
SECURITY.

     Whenever any provision of this Indenture or a Debt Security contemplates
that certification be given by a Person entitled to delivery of a Bearer
Security, such certification shall be provided substantially in the form of
Exhibit A-1 and, if applicable, A-2 hereto, with only such changes as shall be
approved by the Company and consented to by the Trustee, whose consent shall not
unreasonably be withheld.

     Section 312.   JUDGMENTS.

                                      -31-
<Page>

     The Company agrees that, to the fullest extent possible under applicable
law and except as may otherwise be specified as contemplated in Section 301, (a)
the obligation, if any, of the Company to pay the principal of (and premium, if
any) and interest on the Debt Securities of any series and any appurtenant
coupons in a Foreign Currency, composite currency or Dollars (the "Designated
Currency") as may be specified pursuant to Section 301 is of the essence, and
judgments in respect of such Debt Securities shall be given in the Designated
Currency; (b) the obligation of the Company to make payments in the Designated
Currency of the principal of (and premium, if any) and interest on such Debt
Securities and any appurtenant coupons shall, notwithstanding any payment in any
other currency (whether pursuant to a judgment or otherwise), be discharged only
to the extent of the amount in the Designated Currency that the Holder receiving
such payment may, in accordance with normal banking procedures, purchase with
the sum paid in such other currency (after any premium and cost of exchange) in
the country of issue of the Designated Currency in the case of Foreign Currency
or Dollars or in the international banking community in the case of a composite
currency on the Business Day immediately following the day on which such Holder
receives such payment; (c) if the amount in the Designated Currency that may be
so purchased for any reason falls short of the amount originally due, the
Company shall pay such additional amounts as may be necessary to compensate for
such shortfall; and (d) any obligation of the Company not discharged by such
payment shall be due as a separate and independent obligation and, until
discharged as provided herein, shall continue in full force and effect.

     Section 313.   CUSIP NUMBERS.

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

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

     Section 401.   SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Debt Securities herein expressly provided for and rights to receive payments of
principal and interest thereon and any right to receive additional amounts, as
provided in Section 1006) and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture when

          (1)    either

                                      -32-
<Page>

          (A)    all Debt Securities theretofore authenticated and delivered and
     all coupons appertaining thereto (other than (i) coupons appertaining to
     Bearer Securities surrendered in exchange for Registered Securities and
     maturing after such exchange, surrender of which is not required or has
     been waived as provided in Section 305, (ii) Debt Securities and coupons
     which have been destroyed, lost or stolen and which have been replaced or
     paid as provided in Section 306, (iii) coupons appertaining to Bearer
     Securities called for redemption or surrendered for repayment and maturing
     after the relevant Redemption Date or Repayment Date, as appropriate,
     surrender of which has been waived as provided in Section 1106 or 1303 and
     (iv) Debt Securities and coupons for whose payment money and/or Government
     Obligations have theretofore been deposited in trust or segregated and held
     in trust by the Company and thereafter repaid to the Company or discharged
     from such trust, as provided in Section 1003) have been delivered to the
     Trustee cancelled or for cancellation; or

          (B)    all such Debt Securities not theretofore delivered to the
     Trustee for cancellation

          (i)    have become due and payable, or

          (ii)   will become due and payable at their Stated Maturity within one
     year, or

          (iii)  are to be called for redemption within one year under
     arrangements satisfactory to the Trustee for the giving of notice of
     redemption by the Trustee in the name, and at the expense, of the Company,
     and the Company, in the case of (B)(i), (B)(ii) or (B)(iii) above, has
     irrevocably deposited or caused to be deposited with the Trustee as trust
     funds in trust for the purpose money and/or Government Obligations the
     payments of principal and interest on which when due (and without
     reinvestment) will provide money in such amounts as will (together with any
     money irrevocably deposited in trust with the Trustee, without investment)
     be sufficient to pay and discharge the entire indebtedness on such Debt
     Securities and coupons of such series for principal (and premium, if any)
     and interest, and any mandatory sinking fund, repayment or analogous
     payments thereon, on the scheduled due dates therefor to the date of such
     deposit (in the case of Debt Securities and coupons which have become due
     and payable) or to the Stated Maturity or Redemption Date, if any, and all
     Repayment Dates (in the case of Debt Securities repayable at the option of
     the Holders thereof); provided, however, that in the event a petition for
     relief under any applicable Federal or state bankruptcy, insolvency,
     reorganization or other similar law is filed with respect to the Company
     within 91 days after the deposit, the obligations of the Company under the
     Indenture with respect to the Debt Securities of such series shall not be
     deemed terminated or discharged, and in such event the Trustee shall be
     required to return the deposited money and Government Obligations then held
     by the Trustee to the Company;

          (2)    the Company has paid or caused to be paid all other sums
     payable hereunder by the Company; and

                                      -33-
<Page>

          (3)    the Company has delivered to the Trustee an
     Officers'Certificate and an Opinion of Counsel each stating that all
     conditions precedent herein provided for relating to the satisfaction and
     discharge of this Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607 and, if money or
Government Obligations shall have been deposited with the Trustee pursuant to
Subclause (B) of Clause (1) of this Section, the obligations of the Trustee
under Section 402 and the last paragraph of Section 1003 shall survive.

     Section 402.   APPLICATION OF TRUST MONEY AND GOVERNMENT OBLIGATIONS.

          (a)    Subject to the provisions of the last paragraph of
     Section 1003, all money and Government Obligations deposited with the
     Trustee pursuant to Section 401, 403 or 1501 shall be held in trust and
     such money and the principal and interest received on such Government
     Obligations shall be applied by it, in accordance with the provisions of
     the Debt Securities, any coupons and this Indenture, to the payment, either
     directly or through any Paying Agent (including the Company acting as its
     own Paying Agent) as the Trustee may determine, to the Persons entitled
     thereto, of the principal (and premium, if any) and interest for whose
     payment such money or Government Obligations have been deposited with the
     Trustee.

          (b)    The Trustee shall deliver or pay to the Company from time to
     time upon Company Request any Government Obligations or money held by it as
     provided in Section 403 or 1501 which, in the opinion of a nationally
     recognized firm of independent public accountants expressed in a written
     certification thereof delivered to the Trustee, are then in excess of the
     amount thereof which then would have been required to be deposited for the
     purpose for which such Government Obligations or money were deposited or
     received.

          (c)    The Trustee shall deliver to the Company from time to time upon
     Company Request any Government Obligations held by it as provided in
     Section 403 or 1501, provided that the Company in substitution therefor
     simultaneously delivers to the Trustee, money or other Government
     Obligations which, in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee, would then be sufficient to satisfy the Company's
     payment obligations in respect of the Debt Securities in the manner
     contemplated by Section 403 or 1501.

     Section 403.   SATISFACTION, DISCHARGE AND DEFEASANCE OF DEBT SECURITIES OF
ANY SERIES.

     If this Section 403 is specified, as contemplated by Section 301, to be
applicable to Debt Securities of any series, then, notwithstanding Section 401,
(i) the Company shall be deemed to have paid and discharged the entire
indebtedness on all the Outstanding Debt Securities of any such series and
related coupons; (ii) the provisions of this Indenture as it relates to such
Outstanding Debt Securities and related coupons shall no longer be in effect
(except as to (A) the rights of Holders of Debt Securities to receive, from the
trust fund described in subparagraph (1) below, payment of (x) the principal of
(and premium, if any) and any installment of principal of

                                      -34-
<Page>

(and premium, if any) or interest on such Debt Securities and related coupons on
the Stated Maturity of such principal (and premium, if any) or installment of
principal (and premium, if any) or interest or (y) any mandatory sinking fund,
repayment or analogous payments applicable to the Debt Securities of that series
on that day on which such payments are due and payable in accordance with the
terms of this Indenture and of such Debt Securities, (B) the Company's
obligations with respect to such Debt Securities under Sections 304, 305, 306,
1002, 1003 and 1006, and (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, including those under Section 607 hereof); and (iii)
the Trustee, at the expense of the Company, shall, upon Company Order, execute
proper instruments acknowledging satisfaction and discharge of such
indebtedness, when

          (1)    either

          (A)    with respect to all Outstanding Debt Securities of such series
     and related coupons, with reference to this Section 403, the Company has
     deposited or caused to be deposited with the Trustee irrevocably, as trust
     funds in trust, money and/or Government Obligations the payments of
     principal and interest on which when due (and without reinvestment) will
     provide money in such amounts as will (together with any money irrevocably
     deposited in trust with the Trustee, without investment) be sufficient to
     pay and discharge (i) the principal of (and premium, if any) and interest
     on the Outstanding Debt Securities of that series on the Stated Maturity of
     such principal or interest or, if such series may be redeemed by the
     Company prior to the Stated Maturity thereof and the Company shall have
     given irrevocable instructions to the Trustee to effect such redemption, at
     the date fixed for such redemption pursuant to Article Eleven, and (ii) any
     mandatory sinking fund payments or analogous payments applicable to Debt
     Securities of such series on the date on which such payments are due and
     payable in accordance with the terms of this Indenture and of such Debt
     Securities; or

          (B)    the Company has properly fulfilled such other means of
     satisfaction and discharge as is specified, as contemplated by Section 301,
     to be applicable to the Debt Securities of such series;

          (2)    Company has paid or caused to be paid all sums payable with
     respect to the Outstanding Debt Securities of such series and related
     coupons;

          (3)    such deposit will not result in a breach of, or constitute a
     default under, this Indenture or any other agreement or instrument to which
     the Company is a party or by which it is bound;

          (4)    no Event of Default or event which, with the giving of notice
     or lapse of time, or both, would become an Event of Default pursuant to
     Section 501(1), (2), (3), (6) or (7) with respect to the Debt Securities of
     such series shall have occurred and be continuing on the date of such
     deposit and no Event of Default under Section 501(6) or Section 501(7) or
     event which, with the giving of notice or lapse of time, or both, would
     become an Event of Default under Section 501(6) or Section 501(7) shall
     have occurred and be continuing on the 91st day after such date; provided,
     however, that should that

                                      -35-
<Page>

     condition fail to be satisfied on or before such 91st day, the Trustee
     shall promptly, upon satisfactory receipt of evidence of such failure,
     return such deposit to the Company;

          (5)    if the Debt Securities of that series are then listed on any
     domestic or foreign securities exchange, the Company shall have delivered
     to the Trustee an Opinion of Counsel to the effect that such deposit,
     defeasance and discharge will not cause such Debt Securities to be
     delisted; and

          (6)    the Company has delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the satisfaction and discharge of
     the entire indebtedness of all Outstanding Debt Securities and related
     coupons have been complied with.

     Any deposits with the Trustee referred to in Section 403(1)(A) above shall
be irrevocable and shall be made under the terms of an escrow or trust agreement
in form and substance satisfactory to the Trustee. If any Outstanding Debt
Securities of such series are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with any
mandatory sinking fund requirement, the applicable escrow or trust agreement
shall provide therefor and the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company.

     Upon the satisfaction of the conditions set forth in this Section 403 with
respect to all the Outstanding Debt Securities of any series, the terms and
conditions of such series, including the terms and conditions with respect
thereto set forth in this Indenture, shall no longer be binding upon, or
applicable to, the Company; provided that the Company shall not be discharged
from any payment obligations in respect of Debt Securities of such series which
are deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law.

     Notwithstanding the cessation, termination and discharge of all
obligations, covenants and agreements (except as provided above in this Section
403) of the Company under this Indenture with respect to any series of Debt
Securities, the obligations of the Company to the Trustee under Section 607, and
the obligations of the Trustee under Section 402 and the last paragraph of
Section 1003, shall survive with respect to such series of Debt Securities.

                                  ARTICLE FIVE

                                    REMEDIES

     Section 501.   EVENTS OF DEFAULT.

     "Event of Default", wherever used herein with respect to Debt Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law, pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                                      -36-
<Page>

          (1)    default in the payment of any interest upon any Debt Security
     of such series when it becomes due and payable, and continuance of such
     default for a period of 30 days; or

          (2)    default in the payment of the principal of (or premium, if any,
     on) any Debt Security of such series at its Maturity; or

          (3)    default in the deposit of any sinking fund payment, when and as
     due by the terms of a Debt Security of such series; or

          (4)    default in the performance, or breach, of any covenant or
     warranty of the Company in this Indenture (other than a covenant or
     warranty a default in whose performance or whose breach is elsewhere in
     this Section specifically dealt with or which has expressly been included
     in this Indenture solely for the benefit of Debt Securities of a series
     other than such series), and continuance of such default or breach for a
     period of 90 days after there has been given by registered or certified
     mail, to the Company by the Trustee, or to the Company and the Trustee by
     the Holders of at least 25% in principal amount of the Outstanding Debt
     Securities of such series, a written notice specifying such default or

     which there may be issued or by which there may be secured or evidenced any
     Debt by the Company or any Subsidiary (including this Indenture), whether
     such Debt now exists or shall hereafter be created, which default shall
     have resulted in such Debt in an outstanding principal amount in excess of
     $50 million becoming or being declared due and payable prior to the date on
     which it would otherwise have become due and payable, without such
     acceleration having been rescinded or annulled, or such Debt having been
     discharged, within a period of 10 days after there shall have been given,
     by registered or certified mail, to the Company by the Trustee or to the
     Company and the Trustee by the Holders of at least 25% in principal amount
     of the Outstanding Securities of that series a written notice specifying
     such default and requiring the Company to cause such acceleration to be

     such notice is a "Notice of Default" hereunder; or

          (6)    the entry by a court having jurisdiction in the premises of (A)
     a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or state bankruptcy,
     insolvency, reorganization or other similar law or (B) a decree or order
     adjudging the Company a bankrupt or insolvent, or approving as properly
     filed a petition seeking reorganization, arrangement, adjustment or
     composition of or in respect of the Company under any applicable Federal or
     State law, or appointing a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or other similar official of the Company or of any
     substantial part of its property, or ordering the winding up or liquidation
     of its affairs, and 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 90
     consecutive days; or

                                      -37-
<Page>

          (7)    the commencement by the Company of a voluntary case or
     proceeding under any applicable Federal or state bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or state bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or State law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a

     official of the Company or of any substantial part of its property, or the
     making by it of an assignment for the benefit of creditors, or the
     admission by it in writing of its inability to pay its debts generally as
     they become due, or the taking of corporate action by the Company in
     furtherance of any such action; or

          (8)    any other Event of Default, if any, provided with respect to
     Debt Securities of such series specified as contemplated by Section 301.

     Section 502.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default with respect to Debt Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of Outstanding
Debt Securities of such series may declare the principal amount (or, if the Debt
Securities of such series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of such series) of and
all accrued but unpaid interest on all the Debt Securities of such series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by such Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable. Upon
payment of such amount, all obligations of the Company in respect of the payment
of principal of the Debt Securities of such series shall terminate.

     At any time after such a declaration of acceleration with respect to Debt
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Debt Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

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

          (A)    all overdue installments of interest on all Debt Securities of
     such series,

          (B)    the principal of (and premium, if any, on) any Debt Securities
     of such series which have become due otherwise than by such declaration of
     acceleration and interest thereon at the rate or rates prescribed therefor
     in such Debt Securities,

                                      -38-
<Page>

          (C)    to the extent that payment of such interest is lawful, interest
     upon overdue installments of interest at the rate or rates prescribed
     therefor in such Debt Securities, and

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

          (2)    all Events of Default with respect to Debt Securities of such
     series, other than the non-payment of the principal of Debt Securities of
     such series which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 513.

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

     Section 503.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

     The Company covenants that if:

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

          (2)    default is made in the payment of the principal of (or premium,
     if any, on) any Debt Security at the Maturity thereof, the Company will,
     upon demand of the Trustee, pay to it, for the benefit of the Holders of
     such Debt Securities and any related coupons, the amount then due and
     payable on such Debt Securities and coupons for principal (and premium, if
     any) and interest and, to the extent that payment of such interest shall be
     legally enforceable, interest upon the overdue principal (and premium, if
     any) and upon overdue installments of interest, at the rate or rates
     prescribed therefor in such Debt Securities, and, in addition thereto, such
     further amount as shall be sufficient to cover the costs and expenses of
     collection, including the reasonable compensation, expenses, disbursements
     and advances of the Trustee, its agents and counsel.

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

     If an Event of Default with respect to Debt Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Debt Securities of such
series and any related coupons by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this

                                      -39-
<Page>

Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

     Section 504.   TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceedings, or any voluntary or involuntary case under the Federal
bankruptcy laws as now or hereafter constituted, relative to the Company or any
other obligor upon the Debt Securities of a particular series or any related
coupons or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of such Debt
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal or interest) shall be
entitled and empowered, by intervention in such proceedings or otherwise,

          (1)    to file and prove a claim for the whole amount of principal
     (and premium, if any) and interest owing and unpaid in respect of the Debt
     Securities of such series and any appurtenant coupons and to file such
     other papers or documents as may be necessary or advisable in order to have
     the claims of the Trustee (including any claim for the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel) and of the Holders allowed in such judicial proceeding,
     and

          (2)    to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

     and any receiver, assignee, trustee, custodian, 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 it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

     Nothing herein contained 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 Debt
Securities or any coupons 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 505.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBT
SECURITIES OR COUPONS.

     All rights of action and claims under this Indenture or the Debt Securities
or coupons may be prosecuted and enforced by the Trustee without the possession
of any of the Debt Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name, as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be

                                      -40-
<Page>

for the ratable benefit of the Holders of the Debt Securities and coupons in
respect of which such judgment has been recovered.

     Section 506.   APPLICATION OF MONEY COLLECTED.

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

     FIRST: To the payment of all amounts due the Trustee under Section 607;

     SECOND: To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Debt Securities and any coupons, in
respect of which or for the benefit of which such money has been collected
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Debt Securities and any coupons for principal (and
premium, if any) and interest, respectively. The Holders of each series of Debt
Securities denominated in Euro, any other composite currency or a Foreign
Currency and any matured coupons relating thereto shall be entitled to receive a
ratable portion of the amount determined by the Exchange Rate Agent by
converting the principal amount Outstanding of such series of Debt Securities
and matured but unpaid interest on such series of Debt Securities in the
currency in which such series of Debt Securities is denominated into Dollars at
the Exchange Rate as of the date of declaration of acceleration of the Maturity
of the Debt Securities; and

     THIRD: The balance, if any, to the Company.

     Section 507.   LIMITATION ON SUITS.

     No Holder of any Debt Securities of any series or any related coupons shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless

          (1)    such Holder has previously given written notice to the Trustee
     of a continuing Event of Default with respect to the Debt Securities of
     such series;

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

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

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

                                      -41-
<Page>

          (5)    no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Debt Securities of such series; it
     being understood and intended that no one or more of such Holders shall
     have any right in any manner whatever by virtue of, or by availing of, any
     provision of this Indenture to affect, disturb or prejudice the rights of
     any other such Holders (it being understood that the Trustee does not have
     an affirmative duty to ascertain whether or not such actions or
     forebearances are unduly prejudicial to such Holders), or to obtain or to
     seek to obtain priority or preference over any other of such Holders or to
     enforce any right under this Indenture, except in the manner herein
     provided and for the equal and ratable benefit of all of such Holders.

     Section 508.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
AND INTEREST.

     Notwithstanding any other provision in this Indenture, the Holder of any
Debt Security or coupon shall have the right which is absolute and unconditional
to receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Debt Security or payment of such coupon on the
respective Stated Maturity or Maturities expressed in such Debt Security or
coupon (or, in the case of redemption or repayment, on the Redemption Date or
the Repayment Date, as the case may be) and to institute suit for the
enforcement of any such payment, and such right shall not be impaired without
the consent of such Holder.

     Section 509.   RESTORATION OF RIGHTS AND REMEDIES.

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

     Section 510.   RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided in Section 306, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 511.   DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee or of any Holder of any Debt Security
or coupon to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be

                                      -42-
<Page>

exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

     Section 512.   CONTROL BY HOLDERS OF DEBT SECURITIES.

     The Holders of a majority in principal amount of the Outstanding Debt
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee with respect to the Debt
Securities of such series, provided, that

          (1)    such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (2)    subject to the provisions of Section 601, the Trustee shall
     have the right to decline to follow any such direction if the Trustee in
     good faith shall, by a Responsible Officer or Responsible Officers of the
     Trustee, determine that the proceedings so directed would be unjustly
     prejudicial to the Holders of Debt Securities of such series not joining in
     any such direction; and

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

     Section 513.   WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in principal amount of the
Outstanding Debt Securities of any series may on behalf of the Holders of all
the Debt Securities of any such series and any related coupons waive any past
default hereunder with respect to such series and its consequences, except a
default

          (1)    in the payment of the principal of (or premium, if any) or
     interest on any Debt Security of such series, or

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

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

     Section 514.   UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Debt Security
or coupon by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant

                                      -43-
<Page>

in such suit, having a due regard to the merits and good faith of the claims or
defenses made by such party litigant, but the provisions of this Section shall
not apply to any suit instituted by the Company or the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 25% in principal amount of the Outstanding Debt Securities of any series,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of (or premium, if any) or interest on any Debt Security or the
payment of any coupons on or after the respective Stated Maturity or Maturities
expressed in such Debt Security or coupon (or, in the case of redemption or
repayment, on or after the Redemption Date or Repayment Date, as the case may
be).

     Section 515.   WAIVER OF STAY OR EXTENSION LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law whenever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefits or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

     Section 601.   CERTAIN DUTIES AND RESPONSIBILITIES.

          (a)    Except during the continuance of an Event of Default,

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

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

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

                                      -44-
<Page>

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

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

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

          (3)    the Trustee shall not be liable with respect to any action
     taken or omitted to be taken by it in good faith in accordance with the
     direction of the Holders of a majority in principal amount of the
     Outstanding Securities of any series, determined as provided in Sections
     101, 104 and 512, relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred upon the Trustee, under this Indenture with respect to
     the Debt Securities of such series; and

          (4)    no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

     Section 602.   NOTICE OF DEFAULT.

     If a default occurs hereunder with respect to Debt Securities of any series
the Trustee shall transmit by mail to all Holders of Debt Securities of such
series notice of such default as and to the extent provided by the Trust
Indenture Act; provided, however, that in the case of any default of the
character specified in Section 501(4) with respect to Debt Securities of such
series no such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Debt Securities of such series.

     Section 603.   CERTAIN RIGHTS OF TRUSTEE.

     Except as otherwise provided in Section 601:

          (a)    the Trustee may conclusively rely and shall be protected in
     acting or refraining from acting upon any signature, resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     direction, consent, order, bond, debenture, note, coupon or other paper or
     document believed by it to be genuine and to have been signed or presented
     by the proper party or parties;

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

                                      -45-
<Page>

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

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

          (e)    the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders of Debt Securities of such series or any related
     coupons pursuant to this Indenture, unless such Holders shall have offered
     to the Trustee security or indemnity satisfactory to the Trustee against
     the costs, expenses and liabilities which might be incurred by it in
     compliance with such request or direction;

          (f)    the Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, coupon, other evidence of indebtedness or other
     paper or document, but the Trustee, in its discretion, may make such
     further inquiry or investigation into such facts or matters as it may see
     fit, and, if the Trustee shall determine to make such further inquiry or
     investigation, it shall be entitled to examine the books, records and
     premises of the Company, personally or by agent or attorney, other than any
     such books or records containing information as to the affairs of the
     customers of the Company or any of its subsidiaries; provided that the
     Trustee may examine such books and records relating to customers to the
     extent that such books and records contain information as to any payments
     made to such customers in their capacity as Holders of Debt Securities;
     provided, further, that the Trustee shall treat all information regarding
     the Company which it receives pursuant to this Indenture and its duties
     hereunder as confidential and shall not disclose such information unless
     necessary in order to fulfill its duties under this Indenture or the Trust
     Indenture Act;

          (g)    the Trustee may execute any of the trusts or powers hereunder
     or perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; no Exchange Rate Agent, Global Exchange Agent, Depositary or
     Paying Agent shall be deemed an agent of the Trustee and the Trustee shall
     not be responsible for any act or omission by any of them;

          (h)    the Trustee shall not be liable for any action taken, suffered,
     or omitted to be taken by it in good faith and reasonably believed by it to
     be authorized or within the discretion or rights or powers conferred upon
     it by this Indenture;

          (i)    in no event shall the Trustee be responsible or liable for
     special, indirect, or consequential loss or damage of any kind whatsoever
     (including, but not limited to,

                                      -46-

     loss of profit) irrespective of whether the Trustee has been advised of the
     likelihood of such loss or damage and regardless of the form of action;

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

          (k)    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 each agent, custodian and other
     Person employed to act hereunder; and

          (l)    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 604.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBT SECURITIES.

     The recitals contained herein and in the Debt Securities, except the
Trustee's certificates of authentication, and in any coupons, and the
information in any registration statement, including all attachments thereto,
except information provided by the Trustee therein, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debt Securities of any series or any
coupons. The Trustee shall not be accountable for the use or application by the
Company of any Debt Securities or the proceeds thereof. The Trustee shall not be
responsible for and makes no representations as to the Company's ability or
authority to issue Bearer Securities or the lawfulness thereof.

     Section 605.   MAY HOLD DEBT SECURITIES OR COUPONS.

     The Trustee, any Paying Agent, the Security Registrar or any other agent of
the Company or the Trustee, in its individual or any other capacity, may become

     Section 606.   MONEY HELD IN TRUST.

     Money held by the Trustee or any Paying Agent in trust hereunder need not
be segregated from other funds except to the extent required by law. Neither the
Trustee nor any Paying Agent shall be under any liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.

     Section 607.   COMPENSATION AND REIMBURSEMENT.

                                      -47-
<Page>

     The Company agrees

          (1)    to pay to the Trustee from time to time compensation for all
     services rendered by it hereunder which shall have from time to time been
     separately agreed to by the Company and the Trustee in writing (which
     compensation shall not be limited by any provision of law in regard to the
     compensation of a trustee of an express trust);

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

          (3)    to indemnify each of the Trustee or any predecessor Trustee and
     their agents for, and to hold them harmless against, any and all loss,
     damage, claims, liability or expense, including taxes (other than taxes
     based upon, measured by or determined by the income of the Trustee),
     arising out of or in connection with the acceptance or administration of
     the trust or trusts hereunder, including the costs and expenses of
     defending itself against any claim (whether asserted by the Company, or any
     Holder or any other Person) or liability in connection with the exercise or
     performance of any of its powers or duties hereunder, or in connection with
     enforcing the provisions of this Section, except to the extent that such
     loss, damage, claim, liability or expense is due to its own negligence or
     bad faith.

     The Trustee shall promptly notify the Company of any claim for which it may
seek indemnification pursuant to the provisions of this Indenture. The Company
shall be entitled to participate in, and to the extent that it shall wish, to
assume the defense of such claim, with counsel satisfactory to the Trustee (and
the Trustee shall cooperate in the defense thereof), and after notice from the
Company to the Trustee of the Company's election so to assume the defense
thereof, the Company shall not be liable to the Trustee under this Indenture for
any legal or other expenses subsequently incurred by the Trustee in connection
with the defense thereof other than reasonable costs of investigation; provided,
however, that the Trustee may only employ separate counsel at the expense of the
Company if in the judgment of the Trustee (i) a conflict of interest exists by
reason of common representation or (ii) there are legal defenses available to
the Trustee that are different from or are in addition to those available to the
Company or if all parties commonly represented do not agree as to the action (or
inaction) of counsel. The Company shall not be obligated under any settlement
agreement relating to any claim under this Indenture to which it has not agreed
in writing.

     As security for the performance of the obligations of the Company under
this Section the Trustee shall have a claim prior to the Debt Securities and any
coupons upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (and premium, if any)
or interest on particular Debt Securities or any coupons.

     The provisions of this Section 607 shall survive the resignation or removal
of the Trustee and the termination of this Indenture.

                                      -48-

     Section 608.   DISQUALIFICATION; CONFLICTING INTERESTS.

     If the Trustee has or shall acquire any conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest with respect to Debt Securities of any series by virtue of being a
trustee under this Indenture with respect to any particular series of Debt
Securities.

     Section 609.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be a Trustee hereunder which shall be a
corporation that is eligible pursuant to the Trust Indenture Act to act as such
and organized and doing business under the laws of the United States, any State
thereof or the District of Columbia, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000, and subject to supervision or examination by Federal or State
authority; provided, however, that if Section 310(a) of the Trust Indenture Act
or the rules and regulations of the Commission under the Trust Indenture Act at
any time permit a corporation organized and doing business under the laws of any
other jurisdiction to serve as trustee of an indenture qualified under the Trust
Indenture Act, this Section 609 shall be automatically amended to permit a
corporation organized and doing business under the laws of any such other
jurisdiction to serve as Trustee hereunder. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

     Section 610.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

          (a)    No resignation or removal of the Trustee and no appointment of
     a successor Trustee pursuant to this Article shall become effective until
     the acceptance of appointment by the successor Trustee under Section 611.

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

          (c)    The Trustee may be removed at any time with respect to the Debt
     Securities of any series by the Company or by Act of the Holders of a
     majority in principal amount of the Outstanding Debt Securities of such
     series, delivered to the Trustee and to the Company.

          (d)    If at any time:

                                      -49-
<Page>

          (1)    the Trustee shall fail to comply with Section 608 with respect
     to the Debt Securities of any series after written request therefor by the
     Company or by any Holder who has been a bona fide Holder of a Debt Security
     of such series for at least six months, or

          (2)    the Trustee shall cease to be eligible under Section 609 with
     respect to any series of Debt Securities and shall fail to resign after
     written request therefor by the Company or by any such Holder, or

          (3)    the Trustee shall become incapable of acting with respect to
     any series of Debt Securities or a decree or order for relief by a court
     having jurisdiction in the premises shall have been entered in respect of
     the Trustee in an involuntary case under the Federal bankruptcy laws, as
     now or hereafter constituted, or any other applicable Federal or State
     bankruptcy, insolvency or similar law; or a decree or order by a court
     having jurisdiction in the premises shall have been entered for the
     appointment of a receiver, custodian, liquidator, assignee, trustee,
     sequestrator or other similar official of the Trustee or of its property or
     affairs, or any public officer shall take charge or control of the Trustee
     or of its property or affairs for the purpose of rehabilitation,
     conservation, winding up or liquidation, or

          (4)    the Trustee shall commence a voluntary case under the Federal
     bankruptcy laws, as now or hereafter constituted, or any other applicable
     Federal or State bankruptcy, insolvency or similar law or shall consent to
     the appointment of or taking possession by a receiver, custodian,
     liquidator, assignee, trustee, sequestrator or other similar official of
     the Trustee or its property or affairs, or shall make an assignment for the
     benefit of creditors, or shall admit in writing its inability to pay its
     debts generally as they become due, or shall take corporate action in
     furtherance of any such action,

          then, in any such case, (i) the Company by a Board Resolution may
          remove the Trustee with respect to such series at any time or (ii)
          subject to Section 514, any Holder who has been a bona fide Holder of
          a Debt Security of any series for at least six months may, on behalf
          of himself and all others similarly situated, petition any court of
          competent jurisdiction for the removal of the Trustee for the Debt
          Securities of such series and the appointment of a successor Trustee.
          In addition, the Company may remove the Trustee if the Company shall
          determine by a Board Resolution that the services provided by the
          Trustee hereunder may be obtained at a substantially lower cost to the
          Company. If an instrument of acceptance by a successor Trustee shall
          not have been delivered to the Trustee within 30 days after the giving
          of such notice of removal, the Trustee that is to be removed may, at
          the expense of the Company, petition any court of competent
          jurisdiction for the appointment of a successor Trustee with respect
          to the Debt Securities of such series.

          (e)    If the Trustee shall resign, be removed or become incapable of
     acting with respect to any series of Debt Securities, or if a vacancy shall
     occur in the office of Trustee for any cause, with respect to the Debt
     Securities of one or more series, the Company, by a Board Resolution, shall
     promptly appoint a successor Trustee or Trustees with respect

                                      -50-
<Page>

     to the Debt Securities of that or those series (it being understood that
     any such successor Trustee may be appointed with respect to the Debt
     Securities of one or more or all of such series and that at any time there
     shall be only one Trustee with respect to the Debt Securities of any
     particular series) and shall comply with the applicable requirements of
     Section 611. If, within one year after such resignation, removal or
     incapability, or the occurrence of such vacancy, a successor Trustee with
     respect to the Debt Securities of any series shall be appointed by Act of
     the Holders of a majority in principal amount of the Outstanding Debt
     Securities of such series delivered to the Company and the retiring
     Trustee, the successor Trustee so appointed shall, forthwith upon its
     acceptance of such appointment, become the successor Trustee with respect
     to the Debt Securities of such series and to that extent supersede the
     successor Trustee appointed by the Company. If no successor Trustee with
     respect to the Debt Securities of any series shall have been so appointed
     by the Company or the Holders and accepted appointment in the manner
     hereinafter provided, any Holder who has been a bona fide Holder of a Debt
     Security of such series for at least six months may, subject to Section
     514, on behalf of himself and all others similarly situated, petition any
     court of competent jurisdiction for the appointment of a successor Trustee
     with respect to the Debt Securities of such series.

          (f)    The Company shall give notice of each resignation and each
     removal of the Trustee with respect to the Debt Securities of any series
     and each appointment of a successor Trustee with respect to the Debt
     Securities of any series by mailing written notice of such event by
     first-class mail, postage prepaid, to the Holders of Registered Securities,
     if any, of such series as their names and addresses appear in the Security
     Register and, if Debt Securities of such series are issuable as Bearer
     Securities, by publishing notice of such event once in an Authorized
     Newspaper in each Place of Payment located outside the United States. Each
     notice shall include the name of the successor Trustee with respect to the
     Debt Securities of such series and the address of its Corporate Trust
     Office.

     Section 611.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

          (a)    In the case of an appointment hereunder of a successor Trustee
     with respect to all Debt Securities, every such successor Trustee so
     appointed shall execute, acknowledge and deliver to the Company and to the
     retiring Trustee an instrument accepting such appointment, and thereupon
     the resignation or removal of the retiring Trustee shall become effective
     and such successor Trustee, without any further act, deed or conveyance,
     shall become vested with all the rights, powers, trusts and duties of the
     retiring Trustee; but, on request of the Company or the successor Trustee,
     such retiring Trustee shall, upon payment of its charges due under Section
     607 hereof, execute and deliver an instrument transferring to such
     successor Trustee all the rights, powers and trusts of the retiring
     Trustee, and shall duly assign, transfer and deliver to such successor
     Trustee all property and money held by such retiring Trustee hereunder.

          (b)    In the case of the appointment hereunder of a successor Trustee
     with respect to the Debt Securities of one or more (but not all) series,
     the Company, the retiring Trustee upon payment of its charges and each
     successor Trustee with respect to the Debt Securities of one or more series
     shall execute and deliver an indenture

                                      -51-
<Page>

     supplemental hereto wherein each successor Trustee shall accept such
     appointment and which (1) shall contain such provisions as shall be
     necessary or desirable to transfer and confirm to, and to vest in, each
     successor Trustee all the rights, powers, trusts and duties of the retiring
     Trustee with respect to the Debt Securities of that or those series to
     which the appointment of such successor Trustee relates, (2) if the
     retiring Trustee is not retiring with respect to all Debt Securities, shall
     contain such provisions as shall be deemed necessary or desirable to
     confirm that all the rights, powers, trusts and duties of the retiring
     Trustee with respect to the Debt Securities of that or those series as to
     which the retiring Trustee is not retiring shall continue to be vested in
     the retiring Trustee, and (3) shall add to or change any of the provisions
     of this Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee, it being
     understood that nothing herein or in such supplemental indenture shall
     constitute such Trustees co-trustees of the same trust and that each such
     Trustee shall be trustee of a trust or trusts hereunder separate and apart
     from any trust or trusts hereunder administered by any other such Trustee;
     and upon the execution and delivery of such supplemental indenture, the
     resignation or removal of the retiring Trustee shall become effective to
     the extent provided therein and each such successor Trustee, without any
     further act, deed or conveyance, shall become vested with all the rights,
     powers, trusts and duties of the retiring Trustee with respect to the Debt
     Securities of that or those series to which the appointment of such
     successor Trustee relates; but, on the request of the Company or any
     successor Trustee, such retiring Trustee shall duly assign, transfer and
     deliver to such successor Trustee all property and money held by such
     retiring Trustee hereunder with respect to the Debt Securities of that or
     those series to which the appointment of such successor Trustee relates.

          (c)    Upon request of any such successor Trustee, the Company shall
     execute any and all instruments for more fully and certainly vesting in and
     confirming to such successor Trustee all such rights, powers and trusts
     referred to in paragraph (a) or (b) of this Section, as the case may be.

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

     Section 612.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the executing or filing of any paper or any further act on the
part of any of the parties hereto. In case any Debt Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion, consolidation or sale to such authenticating Trustee may
adopt such authentication and deliver the Debt Securities so authenticated with
the same effect as if such successor Trustee had itself authenticated such Debt
Securities. In case any Debt Securities shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or that of its

                                      -52-
<Page>

predecessor Trustee, with the full force and effect which this Indenture
provides for the certificate of authentication of the Trustee.

     Section 613.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     If and when the Trustee shall be or shall become a creditor, directly or
indirectly, secured or unsecured, of the Company (or any other obligor upon the
Debt Securities), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding collection of claims against the Company (or any such
other obligor).

     Section 614.   AUTHENTICATING AGENT.

     The Trustee shall upon Company Request appoint one or more Authenticating
Agents (including, without limitation, the Company or any Affiliate thereof)
with respect to one or more series of Debt Securities which shall be authorized
on behalf of the Trustee in authenticating Debt Securities of such series in
connection with the issue, delivery, registration of transfer, exchange, partial
redemption or repayment of such Debt Securities. Wherever reference is made in
this Indenture to the authentication of Debt Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be acceptable to the
Company and, in the case of Registered Securities, must be a corporation
organized and doing business under the laws of the United States or of any State
or the District of Columbia, having a combined capital and surplus of at least
$50,000,000, authorized under such laws to do a trust business and subject to
supervision or examination by Federal or State authorities, and in the case of
Bearer Securities and an authenticating agent who is not organized and doing
business under the laws of the United States or of any State thereof or the
District of Columbia, is subject to supervision or examination by the
appropriate foreign authorities.

     Any corporation succeeding to the corporate agency business of an
authenticating agent shall continue to be an authenticating agent without the
execution or filing of any paper or any further act on the part of the Trustee
or such authenticating agent.

     An authenticating agent may at any time resign with respect to one or more
series of Debt Securities by giving written notice of resignation to the Trustee
and to the Company. The Trustee may at any time terminate the agency of any
authenticating agent with respect to one or more series of Debt Securities by
giving written notice of termination to such authenticating agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination,
or in case at any time an authenticating agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor authenticating agent. Any successor authenticating agent upon
acceptance of its appointment hereunder shall become vested with all rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an authenticating agent herein. No successor authenticating
agent shall be appointed unless eligible under the provisions of this Section.

     The Company agrees to pay to each authenticating agent from time to time
reasonable compensation for its services under this Section.

                                      -53-
<Page>

     The provisions of Sections 104, 111, 306, 309, 603, 604 and 605 shall be
applicable to any authenticating agent.

     Pursuant to each appointment made under this Section, the Debt Securities
of each series covered by such appointment may have endorsed thereon, in lieu of
the Trustee's certificate of authentication, an alternate certificate of
authentication in substantially the following form:

     This is one of the Debt Securities, of the series designated herein,
described in the within-mentioned Indenture.

     year, a list, in such form as the Trustee may reasonably require, of the
     names and addresses of the Holders of Registered Securities as of the

          (2)    at such other times as the Trustee may request in writing,
     within 30 days after the receipt by the Company of any such request, a list
     of similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

provided, however, that if and so long as the Trustee shall be the Security

     Section 702.   PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

          (a)    The Trustee shall preserve, in as current a form as is
     reasonably practicable, the names and addresses of Holders of Registered
     Securities contained in the most recent list furnished to the Trustee as
     provided in Section 701 and the names and addresses of Holders of
     Registered Securities received by the Trustee in its capacity as Paying

          (b)    The rights of Holders to communicate with other Holders with
     respect to their rights under this Indenture or under the Debt Securities,
     and the corresponding rights and privileges of the Trustee, shall be as
     provided by the Trust Indenture Act.

          (c)    Every Holder of Debt Securities or coupons, by receiving and
     holding the same, agrees with the Company and the Trustee that neither the
     Company nor the Trustee shall be held accountable by reason of any
     disclosure of information as to the names and addresses of the Holders made
     pursuant to the Trust Indenture Act.

     Section 703.   REPORTS BY TRUSTEE.

          (a)    The Trustee shall transmit to Holders such reports concerning

          (b)    A copy of each such report shall, at the time of such
     transmission to Holders, be filed by the Trustee with each stock exchange,

reports required to be filed with the Commission pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 shall be filed with the
Trustee within 15 days after the same is so required to be filed with the

     Delivery of such reports, information and documents to the Trustee is for

to which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under

first paragraph of this instrument or any successor corporation which shall
theretofore have become such in the manner presented in this Article) shall be
relieved of all obligations and covenants under this Indenture and the Debt
Securities and any coupons.

transfer.

                             SUPPLEMENTAL INDENTURES

     Section 901.   SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.

     Without the consent of any Holders, the Company, when authorized by a Board
Resolution, and the Trustee, at any time and from time to time, may enter into
one or more indentures supplemental hereto, in form satisfactory to the Trustee,
for any of the following purposes:

          (1)    to evidence the succession of another corporation to the
     Company, and the assumption by such successor of the covenants of the
     Company herein and in the Debt Securities contained; or

          (2)    to add to the covenants of the Company, for the benefit of the
     Holders of all or any series of Debt Securities (and if such covenants are
     to be for the benefit of less than all series of Debt Securities, stating
     that such covenants are expressly being included solely for the benefit of
     such series) or any coupons, to convey, transfer, assign, mortgage or
     pledge any property to or with the Trustee, or to surrender any right or
     power herein conferred upon the Company; or

          (3)    to add any additional Events of Default (and if such Events of
     Default are to be applicable to less than all series of Debt Securities,
     stating that such Events of Default are expressly being included solely to
     be applicable to such series); or

          (4)    to add to, change or eliminate any of the provisions of this
     Indenture to provide that Bearer Securities may be registrable as to
     principal, to change or eliminate any restrictions on the payment of
     principal of (or premium, if any, on) Registered Securities or of principal
     of (or premium, if any, on) or any interest on Bearer Securities, to permit
     Bearer Securities to be issued in exchange for Registered Securities of
     other authorized denominations or to permit or facilitate the issuance of
     Debt Securities in uncertificated form, provided any such action shall not
     adversely affect the interests of the Holders of Debt Securities of any
     series or any related coupons in any material respect; or

          (5)    to change or eliminate any of the provisions of this Indenture,
     provided that any such change or elimination (a) shall become effective
     only when there is no Debt Security Outstanding of any series created prior
     to the execution of such supplemental indenture which is entitled to the
     benefit of such provisions or (b) shall not apply to any Debt Security
     Outstanding; or

                                      -57-
<Page>

          (6)    to establish the form or terms of Debt Securities of any series
     as permitted by Sections 201 and 301; or

          (7)    to secure the Debt Securities; or

          (8)    to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Debt Securities of one
     or more series and to add to or change any of the provisions of this
     Indenture as shall be necessary to provide for or facilitate the
     administration of the trusts hereunder by more than one Trustee, pursuant
     to the requirements of Section 611(b); or

          (9)    to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture which shall not be inconsistent with
     any provision of this Indenture, provided such other provisions shall not
     adversely affect the interests of the Holders of Debt Securities of any
     series or any related coupons in any material respect; or

          (10)   to add to or change or eliminate any provision of this
     Indenture as shall be necessary or desirable in accordance with any
     amendments to the Trust Indenture Act, provided such action shall not
     adversely affect the interest of Holders of Debt Securities of any series
     or any related coupons in any material respect.

     Section 902.   SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Debt Securities of all series affected by such
supplemental indenture, acting together as a class, by Act of said Holders
delivered to the Company and the Trustee, the Company, when authorized by a
Board Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights under this Indenture of the Holders of such
Debt Securities of such series and any related coupons; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Debt Security or coupon affected thereby,

          (1)    change the Stated Maturity of the principal or any installment
     of principal of, or any installment of interest on, any Debt Security, or
     reduce the principal amount thereof or the interest thereon or any premium
     payable upon redemption or repayment thereof, or change any obligation of
     the Company to pay additional amounts pursuant to Section 1006 (except as
     contemplated by Section 801(1) and permitted by Section 901(1)), or reduce
     the amount of the principal of an Original Issue Discount Security that
     would be due and payable upon a declaration of acceleration of the Maturity
     thereof pursuant to Section 502, or change any Place of Payment, or the
     coin or currency in which any Debt Security or the interest thereon or any
     coupon is payable, or impair the right to institute suit for the
     enforcement of any such payment on or after the Stated Maturity thereof
     (or, in the case of redemption or repayment, on or after the Redemption
     Date or Repayment Date, as the case may be), or

                                      -58-
<Page>

          (2)    reduce the percentage in principal amount of the Outstanding
     Debt Securities of any series, the consent of whose Holders is required for
     any such supplemental indenture, or the consent of whose Holders is
     required for any waiver (of compliance with certain provisions of this
     Indenture or certain defaults hereunder and their consequences) provided
     for in this Indenture, or reduce the requirements of Section 1404 for
     quorum or voting, or

          (3)    modify any of the provisions of this Section, Section 513 or
     Section 1009, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Debt Security
     affected thereby; provided, however, that this clause shall not be deemed
     to require the consent of any Holder with respect to changes in the
     references to "the Trustee" and concomitant changes in this Section and
     Section 1009, or the deletion of this proviso, in accordance with the
     requirements of Section 611(b) and 901(8), or

          (4)    adversely affect the right to repayment, if any, of Debt
     Securities of any series at the option of the Holders thereof.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Debt Securities, or which modifies
the rights of the Holders of Debt Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Debt Securities of any other series.

     It shall not be necessary for any Act of Holders of the Debt Securities
under this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

     Section 903.   EXECUTION OF SUPPLEMENTAL INDENTURES.

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

     Section 904.   EFFECT OF SUPPLEMENTAL INDENTURES.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Debt Securities theretofore or thereafter authenticated and delivered
hereunder and of any coupons appertaining thereto shall be bound thereby.

     Section 905.   CONFORMITY WITH TRUST INDENTURE ACT.

                                      -59-
<Page>

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

     Section 906.   REFERENCE IN DEBT SECURITIES TO SUPPLEMENTAL INDENTURES.

     Debt Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Debt Securities of any series and any appurtenant coupons so
modified as to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding Debt
Securities of such series and any appurtenant coupons.

                                   ARTICLE TEN

                                    COVENANTS

     Section 1001.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The Company covenants and agrees for the benefit of each series of Debt
Securities and any appurtenant coupons that it will duly and punctually pay the
principal of (and premium, if any) and interest on the Debt Securities in
accordance with the terms of the Debt Securities, any appurtenant coupons and
this Indenture. Any interest due on Bearer Securities on or before Maturity,
other than additional amounts, if any, payable as provided in Section 1006 in
respect of principal of (or premium, if any, on) such a Debt Security, shall be
payable only upon presentation and surrender of the coupon or coupons for such
interest installments as are evidenced thereby as they severally mature.

     Section 1002.  MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in each Place of Payment for any series of Debt
Securities an office or agency where Debt Securities (but, except as otherwise
provided below, unless such Place of Payment is located outside the United
States, not Bearer Securities or coupons) may be presented or surrendered for
payment, where Debt Securities may be surrendered for registration of transfer
or exchange and where notices and demands to or upon the Company in respect of
the Debt Securities and this Indenture may be served. If Debt Securities of a
series are issuable as Bearer Securities, the Company will maintain, subject to
any laws or regulations applicable thereto, an office or agency in a Place of
Payment for such series which is located outside the United States where Debt
Securities of such series and the related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Debt Securities of such series pursuant to Section 1006); provided, however,
that if the Debt Securities of such series are listed on a stock exchange
located outside the United States and such stock exchange shall so require, the
Company will maintain a Paying Agent in any required city located outside the
United States, as the case may be, so long as the Debt Securities of such series
are listed on such exchange. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of any such office or
agency. If at any time the

                                      -60-
<Page>

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 or demands may be made or served at the Corporate Trust Office, and the
Company hereby appoints __________________ its agent to receive all
presentations, surrenders, notices and demands, except that Bearer Securities of
that series and the related coupons may be resented and surrendered for payment
(including payment of any additional amounts payable on Bearer Securities of
that series pursuant to Section 1006) at the place specified for the purpose
pursuant to Section 301(5).

     No payment of principal of, or premium, if any, or interest on Bearer
Securities shall be made at any office or agency of the Company in the United
States or by check mailed to any address in the United States or by transfer to
an account maintained with a bank located in the United States; provided,
however, payment of principal of and any premium and interest (including
additional amounts payable in respect thereof) on any Bearer Security
denominated in Dollars may be made at an office or agency of, and designated by,
the Company located in the United States if (but only if) payment of the full
amount of such principal, premium, interest or additional amounts in Dollars at
all offices outside the United States maintained for the purpose by the Company
in accordance with this Indenture is illegal or effectively precluded by
exchange controls or other similar restrictions and the Trustee receives an
Opinion of Counsel that such payment within the United States is legal. Unless
otherwise provided as contemplated by Section 301 with respect to any series of
Debt Securities, at the option of the Holder of any Bearer Security or related
coupon, payment may be made by check in the currency designated for such payment
pursuant to the terms of such Bearer Security presented or mailed to an address
outside the United States or by transfer to an account in such currency
maintained by the payee with a bank located outside the United States.

     The Company may also from time to time designate one or more other offices
or agencies (in or outside of such Place of Payment) where the Debt Securities
of one or more series and any related coupons (subject to the preceding
paragraph) may be presented or surrendered for any or all such purposes, and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment for any
series of Debt Securities for such purposes. The Company will give prompt
written notice to the Trustee of any such designation and any change in the
location of any such other office or agency.

     Section 1003.  MONEY FOR DEBT SECURITIES PAYMENTS TO BE HELD IN TRUST.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Debt Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Debt Securities of
such series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
action or failure so to act.

     Whenever the Company shall have one or more Paying Agents with respect to
any series of Debt Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Debt Securities of
such series, deposit with a Paying Agent a sum sufficient

                                      -61-
<Page>

to pay the principal (and premium, if any) or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent with respect to any series of Debt
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will

hold all sums held by it for the payment of the principal of (and premium, if
any) or interest on Debt Securities of such series in trust for the benefit of
the Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided; give the Trustee notice of any default
by the Company (or any other obligor upon the Debt Securities of such series or
any appurtenant coupons) in the making of any payment of principal of (and
premium, if any) or interest on the Debt Securities of such series; and at any
time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying
Agent.

     The Company may at any time, for the purpose of terminating its obligations
under this Indenture with respect to Debt Securities of any series or for any
other purpose, pay, or by Company Order direct any Paying Agent to pay, to the
Trustee all sums held in trust by the Company or such Paying Agent, such sums to
be held by the Trustee upon the same trusts as those upon which such sums were
held by the Company or such Paying Agent; and, upon such payment by any Paying
Agent to the Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

     Any principal and interest received on the Government Obligations deposited
with the Trustee or any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest on any Debt Security of any series or any money on
deposit with the Trustee or any Paying Agent representing amounts deducted from
the Redemption Price or Repayment Price with respect to unmatured coupons not
presented upon redemption or exercise of the Holder's option for repayment
pursuant to Section 1106 or 1303 and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Debt
Security or any coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money
(including the principal and interest received on Government Obligations
deposited with the Trustee), and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense of the Company cause to be published once, in an Authorized Newspaper of
general circulation in the Borough of Manhattan, The City of New York, and each
Place of Payment or mailed to each such Holder, or both, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication or mailing, any unclaimed
balance of such money then remaining will be repaid to the Company.

                                      -62-

     Section 1004.  CORPORATE EXISTENCE.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises, provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and its
Subsidiaries, taken as a whole, and that the loss thereof is not disadvantageous
in any material respect to the Holders.

     Section 1005.  MAINTENANCE OF PROPERTIES.

     The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times, provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, in
the judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

     Section 1006.  PAYMENT OF ADDITIONAL AMOUNTS.

     If the Debt Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Debt Security of any series
or any coupon appertaining thereto additional amounts upon the terms and subject
to the conditions provided therein. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of (or premium, if any)
or interest on, or in respect of, any Debt Security of any series or the net
proceeds received on the sale or exchange of any Debt Security of any series,
such mention shall be deemed to include mention of the payment of additional
amounts provided for in the terms of such Debt Securities and this Section to
the extent that, in such context, additional amounts are, were or would be
payable in respect thereof pursuant to the provisions of this Section and
express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

     If the Debt Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Debt Securities (or if the Debt Securities of that series will
not bear interest prior to Maturity, the first day on which a payment of
principal (and premium, if any) is made), and at least 10 days prior to each
date of payment of principal (and premium, if any) or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Company will furnish the Trustee and the Company's
principal Paying Agent or Paying Agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of (and premium, if any) or interest on

coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Debt
Securities of that series. If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Debt Securities or coupons and
the Company will pay to the Trustee or such Paying Agent the additional amounts,
if any, required by the terms of such Debt Securities and the first paragraph of
this Section. The Company covenants to indemnify the Trustee and any Paying
Agent for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officers' Certificate furnished pursuant to this Section.

     Section 1007.  PAYMENT OF TAXES.

the same shall become delinquent, all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any 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 or charge whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings or where failure to pay or discharge any such tax, assessment or
charge would not have a material adverse effect on the Holders.

     Section 1008.  OFFICER'S CERTIFICATE AS TO COMPLIANCE.

     The Company will furnish to the Trustee not more than 120 days after the
end of the Company's fiscal year in each year (beginning with December 31, 2004)
a brief certificate from the principal executive, financial or accounting
officer of the Company as to his or her knowledge of the Company's compliance
with all conditions and covenants under this Indenture (such compliance to be

provided under this Indenture), and, if he or she has knowledge of any default,
specifying each such default of which the signer has knowledge and the nature
thereof.

     Section 1009.  STATEMENT BY OFFICERS AS TO DEFAULT.

     The Company shall deliver to the Trustee, as soon as possible and in any
event within five days after the Company becomes aware of the occurrence of any
Event of Default or an event which, with notice or the lapse of time or both,
would constitute an Event of Default, an Officers' Certificate setting forth the
details of such Event of Default or default and the action which the Company
proposes to take with respect thereto.

     Section 1010.  WAIVER OF CERTAIN COVENANTS.

     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Sections 1004, 1005 and 1007 inclusive with respect to
the Debt Securities of any series or any other covenant or condition applicable
to the Debt Securities of any series pursuant to Section 301 unless such
covenant or condition is determined pursuant to Section 301 not to be subject to
this provision if, before the time for such compliance the Holders of at least a
majority in principal amount of the Debt Securities at the time Outstanding to
which such

                                      -64-
<Page>

covenant or condition applies shall, acting together as a class by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such covenant or condition shall
remain in full force and effect.

     Section 1011.  CALCULATION OF ORIGINAL ISSUE DISCOUNT.

     The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on Outstanding Debt
Securities as of the end of such year and (ii) such other specific information
relating to such original issue discount as may then be relevant under the
Internal Revenue Code of 1986, as amended from time to time.

                                 ARTICLE ELEVEN

                          REDEMPTION OF DEBT SECURITIES

     Section 1101.  APPLICABILITY OF ARTICLE.

     Debt Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Debt Securities of any
series) in accordance with this Article.

     Section 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Debt Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company of less than all of the Debt Securities of any series, the Company
shall, at least 45 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee in writing of such Redemption Date and of the principal amount and the
tenor and terms of the Debt Securities of any series to be redeemed. In the case
of any redemption of Debt Securities prior to the expiration of any restriction
on such redemption provided in the terms of such Debt Securities or elsewhere in
this Indenture, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction.

     Section 1103.  SELECTION BY TRUSTEE OF DEBT SECURITIES TO BE REDEEMED.

     Except as otherwise specified as contemplated by Section 301 for Debt
Securities of any series, if less than all the Debt Securities of any series
with like tenor and terms are to be redeemed, the particular Debt Securities to
be redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the Outstanding Debt Securities of such series with like
tenor and terms not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Debt Securities of such series or any integral multiple thereof which is also an
authorized denomination) of the principal amount of Registered Securities or
Bearer Securities (if issued in more than one authorized

                                      -65-
<Page>

denomination) of such series of a denomination larger than the minimum
authorized denomination for Debt Securities of such series.

     The Trustee shall promptly notify the Company in writing of the Debt
Securities selected for redemption and, in the case of any Debt Securities
selected for partial redemption, the principal amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Debt Securities shall relate, in
the case of any Debt Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Debt Security which has been or is to be
redeemed.

     Section 1104.  NOTICE OF REDEMPTION.

     Notice of redemption shall be given in the manner provided in Section 106
not less than 30 nor more than 60 days prior to the Redemption Date, to each
Holder of Debt Securities to be redeemed.

          All notices of redemption shall state:

          (1)    the Redemption Date,

          (2)    the Redemption Price,

          (3)    if less than all Outstanding Debt Securities of any series are
     to be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Debt Securities to be redeemed,

          (4)    that on the Redemption Date the Redemption Price will become
     due and payable upon each such Debt Security to be redeemed, and that
     interest thereon shall cease to accrue on and after said date,

          (5)    the Place or Places of Payment where such Debt Securities,
     together in the case of Bearer Securities with all coupons, if any,
     appertaining thereto maturing after the Redemption Date, are to be
     surrendered for payment of the Redemption Price,

          (6)    that Bearer Securities may be surrendered for payment only at
     such place or places which are outside the United States, except as
     otherwise provided in Section 1002,

          (7)    that the redemption is for a sinking fund, if such is the case,
     and

          (8)    the CUSIP number, if any.

     A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

                                      -66-
<Page>

     Notice of redemption of Debt Securities to be redeemed at the election of
the Company shall be given by the Company, or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

     Section 1105.  DEPOSIT OF REDEMPTION PRICE.

     On or prior to any 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 1003) an amount of
money and/or Government Obligations the payments of principal and interest on
which when due (and without reinvestment) will provide money on or prior to the
Redemption Date in such amounts as will (together with any money irrevocably
deposited in trust with the Trustee, without investment) be sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Debt Securities or portions thereof
which are to be redeemed on that date; provided, however, that deposits with
respect to Bearer Securities shall be made with a Paying Agent or Paying Agents
located outside the United States except as otherwise provided in Section 1002,
unless otherwise specified as contemplated by Section 301.

     Section 1106.  DEBT SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption having been given as aforesaid, the Debt Securities to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Debt Securities shall cease to bear interest and the coupons for
such interest appertaining to any Bearer Securities so to be redeemed, except to
the extent provided below, shall be void. Upon surrender of any such Debt
Security for redemption in accordance with said notice, such Debt Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only upon presentation and surrender of coupons for such
interest (at an office or agency located outside the United States except as
otherwise provided in Section 1002), and provided further, that installments of
interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Debt Securities, or one
or more Predecessor Securities, registered as such on the relevant Record Dates
according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Bearer
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted without
interest thereon; provided, however, that interest represented by coupons shall
be payable only upon presentation and surrender of those

                                      -67-
<Page>

coupons at an office or agency located outside of the United States except as
otherwise provided in Section 1002.

     If any Debt Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Debt Security.

     Section 1107.  DEBT SECURITIES REDEEMED IN PART.

     Any Registered Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company, the Security
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Debt Security without
service charge, a new Registered Security or Registered Securities of the same
series and of like tenor and terms, of any authorized denominations as requested
by such Holder in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Debt Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

     Section 1201.  APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Debt Securities of a series except as otherwise specified as
contemplated by Section 301 for Debt Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Debt Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Debt Securities of any series is herein referred to an "optional
sinking fund payment". If provided for by the terms of Debt Securities of any
series, the amount of any sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Debt Securities of any series as provided for by the terms of Debt
Securities of such series.

     Section 1202.  SATISFACTION OF SINKING FUND PAYMENTS WITH DEBT SECURITIES.

     The Company (1) may deliver Outstanding Debt Securities of a series (other
than any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Debt Securities of a series which have been redeemed
either at the election of the Company pursuant to the terms of such Debt
Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Debt Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Debt Securities of such series required to be made

                                      -68-
<Page>

pursuant to the terms of such Debt Securities as provided for by the terms of
such series; provided that such Debt Securities have not been previously so
credited. Such Debt Securities shall be received and credited for such purpose
by the Trustee at the Redemption Price specified in such Debt Securities for
redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly. If as a result of the delivery or
credit of Debt Securities in lieu of cash payments pursuant to this Section
1202, the principal amount of Debt Securities to be redeemed in order to exhaust
the aforesaid cash payment shall be less than $100,000, the Trustee need not
call Debt Securities for redemption, except upon Company Request, and such cash
payment shall be held by the Trustee or a Paying Agent and applied to the next
succeeding sinking fund payment, provided, however, that the Trustee or such
Paying Agent shall at the request of the Company from time to time pay over and
deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Debt Securities
purchased by the Company having an unpaid principal amount equal to the cash
payment requested to be released to the Company.

     Section 1203.  REDEMPTION OF DEBT SECURITIES FOR SINKING FUND.

     Not less than 45 days prior to each sinking fund payment date for any
series of Debt Securities (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash, the portion thereof, if any, which is to be
satisfied by crediting Debt Securities of that series pursuant to Section 1202
and the basis for any such credit and, prior to or concurrently with the
delivery of such Officers' Certificate, will also deliver to the Trustee any
Debt Securities to be so credited and not theretofore delivered to the Trustee.
Not less than 30 days (unless a shorter period shall be satisfactory to the
Trustee) before each such sinking fund payment date the Trustee shall select the
Debt Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such Debt
Securities shall be made upon the terms and in the manner stated in Sections
1105, 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

     Section 1301.  APPLICABILITY OF ARTICLE.

     Debt Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
their terms and (except as otherwise specified pursuant to Section 301 for Debt
Securities of such series) in accordance with this Article.

     Section 1302.  REPAYMENT OF DEBT SECURITIES.

                                      -69-
<Page>

     Each Debt Security which is subject to repayment in whole or in part at the
option of the Holder thereof on a Repayment Date shall be repaid at the
applicable Repayment Price together with interest accrued to such Repayment Date
as specified pursuant to Section 301.

     Section 1303.  EXERCISE OF OPTION; NOTICE.

     Each Holder desiring to exercise such Holder's option for repayment shall,
as conditions to such repayment, surrender the Debt Security to be repaid in
whole or in part together with written notice of the exercise of such option at
any office or agency of the Company in a Place of Payment, not less than 30 nor
more than 45 days prior to the Repayment Date; provided, however, that surrender
of Bearer Securities together with written notice of exercise of such option
shall be made at an office or agency located outside the United States except as
otherwise provided in Section 1002. Such notice, which shall be irrevocable,
shall specify the principal amount of such Debt Security to be repaid, which
shall be equal to the minimum authorized denomination for such Debt Security or
an integral multiple thereof, and shall identify the Debt Security to be repaid
and, in the case of a partial repayment of the Debt Security, shall specify the
denomination or denominations of the Debt Security or Debt Securities of the
same series to be issued to the Holder for the portion of the principal of the
Debt Security surrendered which is not to be repaid.

     If any Bearer Security surrendered for repayment shall not be accompanied
by all unmatured coupons and all matured coupons in default, such Bearer
Security may be paid after deducting from the Repayment Price an amount equal to
the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Repayment
Price, such Holder shall be entitled to receive the amount so deducted without
interest thereon; provided, however, that interest represented by coupons shall
be payable only at an office or agency located outside the United States except
as otherwise provided in Section 1002.

     The Company shall execute and the Trustee shall authenticate and deliver
without service charge to the Holder of any Registered Security so surrendered a
new Registered Security or Securities of the same series, of any authorized
denomination specified in the foregoing notice, in an aggregate principal amount
equal to any portion of the principal of the Registered Security so surrendered
which is not to be repaid.

     The Company shall execute and the Trustee shall authenticate and deliver
without service charge to the Holder of any Bearer Security so surrendered a new
Registered Security or Securities or new Bearer Security or Securities (and all
appurtenant unmatured coupons and matured coupons in default) or any combination
thereof of the same series of any authorized denomination or denominations
specified in the foregoing notice, in an aggregate principal amount equal to any
portion of the principal of the Debt Security so surrendered which is not to be
paid; provided, however, that the issuance of a Registered Security therefor
shall be subject to applicable laws and regulations, including provisions of the
United States Federal income tax laws and regulations in effect at the time of
the exchange; neither the Company, the Trustee nor

                                      -70-
<Page>

the Security Registrar shall issue Registered Securities for Bearer Securities
if it has received an Opinion of Counsel that as a result of such issuance the
Company would suffer adverse consequences under the United States Federal income
tax laws then in effect and the Company has delivered to the Trustee a Company
Order directing the Trustee not to make such issuances thereafter unless and
until the Trustee receives a subsequent Company Order to the contrary. The
Company shall deliver copies of such Company Order to the Security Registrar.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the repayment of Debt Securities shall relate, in the
case of any Debt Security repaid or to be repaid only in part, to the portion of
the principal of such Debt Security which has been or is to be repaid.

     Section 1304.  ELECTION OF REPAYMENT BY REMARKETING ENTITIES.

     The Company may elect, with respect to Debt Securities of any series which
are repayable at the option of the Holders thereof before their Stated Maturity,
at any time prior to any Repayment Date to designate one or more Remarketing
Entities to purchase, at a price equal to the Repayment Price, Debt Securities
of such series from the Holders thereof who give notice and surrender their Debt
Securities in accordance with Section 1303.

     Section 1305.  SECURITIES PAYABLE ON THE REPAYMENT DATE.

     Notice of exercise of the option of repayment having been given and the
Debt Securities so to be repaid having been surrendered as aforesaid, such Debt
Securities shall, unless purchased in accordance with Section 1304, on the
Repayment Date become due and payable at the price therein specified and from
and after the Repayment Date such Debt Securities shall cease to bear interest
and shall be paid on the Repayment Date, and the coupons for such interest
appertaining to Bearer Securities so to be repaid, except to the extent provided
above, shall be void, unless the Company shall default in the payment of such
price in which case the Company shall continue to be obligated for the principal
amount of such Debt Securities and shall be obligated to pay interest on such
principal amount at the rate borne by such Debt Securities from time to time
until payment in full of such principal amount.
