SECTION 1.04  ACTS OF HOLDERS.

         (a)      Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or
taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by an
agent duly appointed in writing. If Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or
taken by Holders of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in
favor thereof, either in person or by proxies duly appointed in writing, at
any meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of ARTICLE FOURTEEN, or a combination of such
instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or
instruments or record or both are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments and
any such record (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the "ACT" of the Holders signing such
instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent or
proxy or of the holding by any Person of a Security, shall be sufficient for
any purpose of this Indenture and (subject to SECTION 6.01) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved
in the manner provided in SECTION 14.06.

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

         (c)      The Company may, in the circumstances permitted by the
Trust Indenture Act, fix any day as the record date for the purpose of
determining the Holders of Registered Securities of any series entitled to
give or take any request, demand, authorization, direction, notice, consent,
waiver or other action, or to vote on any action, authorized or permitted to
be given or taken by Holders of Securities of such series. If not set by the
Company prior to the first solicitation of a Holder of Securities of such
series made by any Person in respect of any such action, or, in the case of
any such vote, prior to such vote, the record date for any such action or
vote shall be the 30th day (or, if later, the date of the most recent list of
Holders required to be provided pursuant to SECTION 7.01) prior to such first
solicitation or vote, as the case may be. With regard to any record date for
action to be taken by the Holders of one or more series of Securities, only
the Holders of Securities of such series on such date (or their duly
designated proxies) shall be entitled to give or take, or vote on, the
relevant action.

         (d)      The principal amount and serial numbers of Registered
Securities held by any Person, and the date of holding the same, shall be
proved by the Security Register.


                                      11
<Page>

         (e)      The principal amount and serial numbers of Bearer
Securities held by any Person, and the date of holding the same, may be
proved by the production of such Bearer Securities or by a certificate
executed, as depositary, by any trust company, bank, banker or other
depositary, wherever situated, if such certificate shall be deemed by the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate
or affidavit of the Person holding such Bearer Securities, if such
certificate or affidavit is deemed by the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (1) another certificate or affidavit 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 Registered Security, or (4) such
Bearer Security is no longer Outstanding. The principal amount and serial
numbers of Bearer Securities held by any Person, and the date of holding the
same, may also be proved in any other manner which the Trustee deems
sufficient.

         (f)      Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such
action is made upon such Security. Any Holder or subsequent Holder may revoke
the request, demand, authorization, direction, notice, consent, waiver or
other Act as to his Security or portion of his Security; PROVIDED, HOWEVER,
that such revocation shall be effective only if the Trustee receives notice
of such revocation before the date the Act becomes effective.

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

Securities on a Business Day at least twice, the first such publication to be
not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
Holders of Registered Securities by mail, then such notification as shall be
made with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. In any case where notice to Holders
of Registered Securities is 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 to
Holders of Bearer Securities given as provided herein.

         In case by the reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause
it shall be impracticable to publish any notice to Holders of Bearer
Securities as provided above, then such notification to Holders of Bearer
Securities as shall be given with the approval of the Trustee shall
constitute sufficient notice to such Holders for every purpose hereunder.
Neither the 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 to Holders of Registered
Securities given as provided herein.

         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 of Securities 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.

SECTION 1.07  LANGUAGE OF NOTICES, ETC.

         Any request, demand, authorization, direction, notice, consent or
waiver 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 1.08  CONFLICT WITH TRUST INDENTURE ACT.

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

SECTION 1.09  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 1.10  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 1.11  SEPARABILITY CLAUSE.

         In case any provision in this Indenture or the Securities or 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 1.12  BENEFITS OF INDENTURE.

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

SECTION 1.13  GOVERNING LAW.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of laws.

SECTION 1.14  LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or of the
Securities or coupons other than a provision in the Securities of any series
which specifically states that such provision shall apply in lieu of this
Section) 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 or Redemption Date, or at the
Stated Maturity, as the case may be, provided that no interest shall accrue on
the amount so payable for the period from and after such date.

                                   ARTICLE II.
                                 SECURITY FORMS

SECTION 2.01  FORMS GENERALLY.

         The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons shall be in substantially
the form (including temporary or permanent global form) as shall be established
by or pursuant to a Board Resolution of the Company 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, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with law, or with the rules of any securities exchange or to conform to general
usage, all as may, consistently herewith, be determined by the officers
executing such Securities or coupons, as evidenced by their execution of the
Securities or coupons. If temporary Securities of any series are issued in
global form as permitted by SECTION 3.04, the form thereof shall be established
as provided in the preceding sentence. A copy of the Board Resolution of the
Company establishing the forms of Securities or coupons of any series (or any
such temporary global Security) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order contemplated by SECTION 3.03 for the
authentication and delivery of such Securities (or any such temporary global
Security) or coupons.

         Unless otherwise specified as contemplated by SECTION 3.01, Securities
in bearer form shall have interest coupons attached.

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

SECTION 2.02  FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION.

         The Trustee's certificate of authentication shall be in substantially
the following form:


                                       15

         "This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.


                                      BNY MIDWEST TRUST COMPANY,
                                      as Trustee


                                      By:_______________________________________
                                         Authorized Signatory.

SECTION 2.03  SECURITIES IN GLOBAL FORM.

         If Securities of a series are issuable in global form, as contemplated
by SECTION 3.01, then, notwithstanding CLAUSE (10) of SECTION 3.01 and the
provisions of SECTION 3.02, any such Security shall represent such of the
Outstanding Securities of such series as shall be specified therein and may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may be reduced to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee 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 3.03 or SECTION 3.04. Subject to the
provisions of SECTION 3.03 and, if applicable, SECTION 3.04, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to SECTION 3.03 or 3.04
has been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with SECTION 1.02 and need not be
accompanied by an Opinion of Counsel.

         The provisions of the last sentence of SECTION 3.03 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with SECTION 1.02 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of SECTION 3.03.

         Notwithstanding the provisions of SECTIONS 2.01 and 3.07, unless
otherwise specified as contemplated by SECTION 3.01, payment of principal of and
any premium and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein.

SECTION 2.04  FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Book-Entry Security authenticated and delivered hereunder shall
bear a legend in substantially the following form:


                                       16
<Page>

         "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee only
in the limited circumstances described in the Indenture, and no transfer of this
Security (other than a transfer of this Security as a whole by the Depository to
a nominee of the Depository or by a nominee of the Depository to the Depository
or another nominee of the Depository) may be registered except in such limited
circumstances."

                                  ARTICLE III.
                                 THE SECURITIES

         The aggregate principal amount of Securities which may be authenticated

series shall rank equally and PARI PASSU with each other series, but all
Securities issued hereunder shall be subordinate and junior in right of payment,
to the extent and in the manner set forth in ARTICLE SIXTEEN, to all Senior
Indebtedness. There shall be established in or pursuant to a Board Resolution of
the Company and, subject to SECTION 3.03, set forth, or determined in the manner
provided, in an Officers' Certificate, or established in one or more indentures
supplemental hereto, prior to the issuance of Securities of any series:

series pursuant to SECTION 3.04, 3.05, 3.06, 9.06 or 11.07 and except for any
Securities which, pursuant to SECTION 3.03, are deemed never to have been
authenticated and delivered hereunder);

                  (3)      whether Securities of the series are to be issuable
as Registered Securities, Bearer Securities or both, whether any Securities of
the series are to be issuable initially in temporary global form and whether any
Securities of the series are to be issuable in permanent global form, as Book
Entry Securities, or otherwise, with or without coupons and, if so, whether
beneficial owners of interests in any such permanent global Security may
exchange such interests for Securities of such series and of like tenor of any
authorized form and denomination and the circumstances under which any such
exchanges may occur, if other than in the manner provided in SECTION 3.05;

                  (4)      the Person to whom any interest on any Registered
Security of the series shall be payable, if other than the Person in whose name
that Security (or one or more Predecessor Securities) is registered at the close
of business on the Regular Record Date for such interest, the manner in which,
or the Person to whom, any interest on any Bearer Security of the series shall
be payable, if otherwise than upon presentation and surrender of the coupons


                                       17

                  (7)      the place or places where, subject to the
provisions of SECTION 10.02, the principal of and any premium and interest on
Securities of the series shall be payable, any Registered Securities of the
series may be surrendered for registration of transfer and notices and demands
to or upon the Company in respect of the Securities of the series and this
Indenture may be served;

purchase, or repay Securities of the series pursuant to any mandatory
redemption, sinking fund or analogous provisions or at the option of a Holder
thereof and the period or periods within which, the price or prices at which and
the terms and conditions upon which Securities of the series shall be redeemed,

SECTION 1.01;

                  (12)     if the amount of payments of principal of and any

reference to an index, the manner in which such amounts shall be determined;

                  (13)     if other than the principal amount thereof, the
portion of the principal amount of any Securities of the series which shall be

the Securities of the series are to be payable, at the election of the Company
or a Holder thereof, in a currency or currencies, including composite
currencies, other than that or those in which the Securities are stated to be
payable, the currency or currencies in which payment of the principal of and any
premium and interest on Securities of such series as to which such election is

                  (15)     whether the Securities of the series shall be issued
upon original issuance in whole or in part in the form of one or more Book-Entry
Securities and, in such case, (a) the Depository with respect to such Book-
Entry Security or Securities and (b) the circumstances under which any such
Book-Entry Security may be exchanged for Securities registered in the name of,
and any transfer of such Book-Entry Security may be registered to, a Person
other than such Depository or its nominee, if other than as set forth in SECTION
3.05;

                  (16)     if either or both of the provisions of SECTION 13.02
or 13.03 are applicable to the Securities of such series and any additional
means of discharge pursuant to SECTION 13.02 or 13.03 and any additional
conditions to the provisions of SECTION 13.02 or 13.03;

                  (17)     any other Events of Default or covenants with respect
to the Securities of such series;

be inconsistent with the provisions of this Indenture except as permitted by
SECTION 9.01(5)).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be

SECTION 3.02  DENOMINATIONS.

         Unless otherwise provided as contemplated by SECTION 3.01 with respect
to any series of Securities, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in the denomination of $5,000.

SECTION 3.03  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President, its Treasurer or its Chief Financial
Officer, attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or
facsimile. Coupons shall bear the facsimile signature of the Treasurer or any
Assistant Treasurer of the Company.

         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 Securities or
did not hold such offices at the date of such Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupons appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
unless otherwise provided with respect to such series, in connection with its
original issuance, during the "restricted period" (as defined in Section
1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations) (the
"RESTRICTED PERIOD") no Bearer Security shall be mailed or otherwise delivered
to any location in the United States; and PROVIDED, FURTHER, that, unless
otherwise provided with respect to such series, a Bearer Security may be
delivered in connection with its original issuance only if the Person entitled
to receive such Bearer Security shall have furnished a certificate in the form
set forth in Exhibit A to this Indenture, dated no earlier than the
Certification Date. If any Security shall be represented by a permanent global
Bearer Security, then, for purposes of this Section and SECTION 3.04, the
notation of a beneficial owner's interest therein upon original issuance of such
Security or upon exchange of a portion of a temporary global Security shall be
deemed to be delivery in connection with its original issuance during the
restricted period of such beneficial owner's interest in such permanent global
Security. Except as permitted by SECTION 3.06, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant coupons for
interest then matured have been detached and cancelled.

         In authenticating Securities, the Trustee shall be entitled to receive,
and (subject to SECTION 6.01) shall be fully protected in relying upon, an
Opinion of Counsel stating:


                                       20
<Page>

         (a)      that the forms of such Securities and coupons established by
or pursuant to a Board Resolution of the Company as contemplated by SECTION 2.01
have been established in conformity with the provisions of this Indenture;

         (b)      if the terms of such Securities and any coupons have been
established by or pursuant to a Board Resolution of the Company as permitted by
SECTION 3.01, that such terms have been established in conformity with the
provisions of this Indenture; and

         (c)      that such Securities, together with any coupons appertaining
thereto, when authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute valid and legally binding obligations of the Company
enforceable in accordance with their terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization and other laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

         Such Opinion of Counsel shall also cover such other matters as the
Trustee may reasonably request.

         The Trustee shall not be required to authenticate such Securities the
forms or terms of which have been established by or pursuant to a Board
Resolution of the Company if the issue of such Securities pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee.

         Notwithstanding the provisions of SECTION 3.01 and of the two preceding
paragraphs, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to SECTION 3.01 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraphs at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon issuance of the first Security
of such series to be issued.

         After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to SECTION 6.01, the Trustee shall
be fully protected in conclusively relying on) that it is in compliance with
all conditions precedent provided for in this Indenture relating to the
authentication and delivery of such Securities.

         Each Registered Security shall be dated the date of its authentication;
and each Bearer Security shall be dated as of the date of original issuance of
the first Security of such series to be issued.

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


                                       21
<Page>

authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in SECTION 3.09 together with a written statement
(which need not comply with SECTION 1.02 and need not be accompanied by an
Opinion of Counsel) stating that such Security has never been issued and sold
by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

SECTION 3.04  TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive 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 Securities may determine, as
evidenced by their execution of such Securities. In the case of any series
issuable as Bearer Securities, such temporary Securities may be in global form.
A temporary Bearer Security shall be delivered only in compliance with the
conditions set forth in SECTION 3.03.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company maintained pursuant to SECTION 10.02 in a Place of Payment for such
series for the purpose of exchanges of Securities of such series without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured coupons appertaining
thereto) the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like aggregate principal amount of definitive
Securities of the same series and of like tenor of authorized denominations;
PROVIDED, HOWEVER, that no definitive Bearer Security shall be issued in
exchange for a temporary Registered Security.

         If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "COMMON
DEPOSITARY"), for the benefit of Euro-clear and CLEARSTREAM, for credit to
the respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         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 of a series (the "EXCHANGE DATE"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount equal
to the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Security shall


                                       22
<Page>

be surrendered by the Common Depositary to the Trustee, as the Company's
agent for such purpose, to be exchanged, in whole or from time to time in
part, for definitive Securities of that series without charge and the Trustee
shall authenticate and deliver, in exchange for each portion of such
temporary global Security, a like aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor
as the portion of such temporary global Security to be exchanged; PROVIDED,
HOWEVER, that, unless otherwise specified in such temporary global Security,
upon such presentation by the Common Depositary, such temporary global
Security is accompanied by a certificate dated the Exchange

         Date or a subsequent date and signed by Euro-clear as to the portion
of such temporary global Security held for its account then to be exchanged
and a certificate dated the Exchange Date or a subsequent date and signed by
CLEARSTREAM as to the portion of such temporary global Security held for its
account then to be exchanged, each in the form set forth in Exhibit B to this
Indenture. The definitive Securities to be delivered in exchange for any such
temporary global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by SECTION 3.01, and if any combination
thereof is so specified, as requested by the beneficial owner thereof;
PROVIDED, HOWEVER, that no definitive Bearer Security or permanent global
Security shall be delivered in exchange for a temporary Bearer Security except
in compliance with the conditions set forth in SECTION 3.03.

         Unless otherwise specified in the temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged on the Exchange Date for definitive Securities
(and where the form of the definitive Securities is not specified by the
Holder for an interest in a permanent global Security) of the same series and
of like tenor unless, on or prior to the Exchange Date, such beneficial owner
has not delivered to Euro- clear or CLEARSTREAM, as the case may be, a
certificate in the form set forth in Exhibit A to this Indenture dated no
earlier than the Certification Date, copies of which certificate shall be
available from the offices of Euro-clear and CLEARSTREAM, the Trustee, any
Authenticating Agent appointed for such series of Securities and each Paying
Agent and after the Exchange Date, the interest of a beneficial owner of
Securities of a series in a temporary global Security shall be exchanged for
definitive Securities (and where the form of the definitive Securities is not
specified by the Holder for an interest in a permanent global Security) of the
same series and of like tenor following such beneficial owner's delivery to
Euro-clear or CLEARSTREAM, as the case may be, of a certificate in the form
set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date. Unless otherwise specified in such temporary global
Security, any exchange shall be made free of charge to the beneficial owners
of such temporary global Security, except that a Person receiving definitive
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
Securities in person at the offices of Euro-clear or CLEARSTREAM Definitive
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.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by SECTION 3.01, interest payable on a temporary
global


                                       23
<Page>

Security on an Interest Payment Date for Securities of such series shall be
payable to Euro-clear and CLEARSTREAM on such Interest Payment Date upon
delivery by Euro- clear and CLEARSTREAM to the Trustee of a certificate or
certificates in the form set forth in Exhibit B to this Indenture, for credit
without further interest on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such
temporary global Security on such Interest Payment Date and who have each
delivered to Euro-clear or CLEARSTREAM, as the case may be, a certificate in
the form set forth in Exhibit A to this Indenture. Any interest so received by
Euro-clear and CLEARSTREAM and not paid as herein provided shall be returned to
the Trustee immediately prior to the expiration of two years after such
Interest Payment Date in order to be repaid to the Company in accordance with
SECTION 10.03.

SECTION 3.05  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with SECTION 10.02 a register (being the
combined register of the Security Registrar and all transfer agents designated
pursuant to SECTION 10.02 for the purpose of registration of transfer of
Securities and sometimes collectively 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 each series of Registered Securities and
the registration of transfers of such Registered Securities. The Company shall
serve initially as "SECURITY REGISTRAR" for the purpose of registering
Registered Securities and transfers of Registered 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 pursuant to
SECTION 10.02 for such purpose in a Place of Payment for such series, 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 denominations and of a like
aggregate principal amount and tenor.

         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
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Securities to be exchanged at any such office or agency. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Unless otherwise provided with respect to
any series of Securities, Bearer Securities may not be issued in exchange for
Registered Securities.

         At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, 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 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 is furnished to them


                                      24
<Page>

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
10.02, 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 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 proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, 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.

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

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by SECTION 3.01, any permanent global Security shall be
exchangeable only as provided in this paragraph. If the beneficial owners of
interests in a permanent global Security are entitled to exchange such
interests for Securities of such series and of like tenor and principal amount
of another authorized form and denomination, as specified as contemplated by
SECTION 3.01, then without unnecessary delay but in any event not later than
the earliest date on which such interests may be so exchanged, the Company
shall deliver to the Trustee definitive Securities of that series in an
aggregate principal amount equal to the principal amount of such permanent
global Security, executed by the Company. On or after the earliest date on
which such interests may be so exchanged, such permanent global Security shall
be surrendered from time to time in accordance with instructions given to the
Trustee and the Common Depositary (which instructions shall be in writing but
need not comply with SECTION 1.02 or be accompanied by an Opinion of Counsel)
by the Common Depositary or such other depositary or Common Depositary as
shall be specified in the Company Order with respect thereto to the Trustee,
as the Company's agent for such purpose, to be exchanged, in whole or in part,
for definitive Securities of the same series without charge and the Trustee
shall authenticate and deliver, in exchange for each portion of such permanent
global Security, a like aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion
of such permanent global Security to be exchanged which, unless the Securities
of the series are not issuable both as Bearer Securities and as Registered
Securities, as specified as contemplated by SECTION 3.01, shall be in the form
of Bearer Securities or Registered Securities, or any combination thereof, as
shall be specified by the beneficial owner thereof; PROVIDED, HOWEVER, that no
such exchanges may occur during a period beginning at the opening of business
15 days before any selection of Securities of that series is to be redeemed
and ending on

                                      25
<Page>

the relevant Redemption Date; and PROVIDED, FURTHER, that no Bearer Security
delivered in exchange for a portion of a permanent global Security shall be
mailed or otherwise delivered to any location in the United States. Promptly
following any such exchange in part, such permanent global Security shall be
returned by the Trustee to the Common Depositary or such other depositary or
Common Depositary referred to above in accordance with the instructions of the
Company referred to above. If a Registered Security is issued in exchange for
any portion of a permanent global Security after the close of business at the
office or agency where such exchange occurs 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 proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent global
Security is payable in accordance with provisions of this Indenture.

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

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

         No service charge shall be made for any registration of transfer or
exchange of 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 registration of transfer or exchange of Securities, other than
exchanges pursuant to SECTION 3.04, 9.06 or 11.07 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the mailing or publication of a notice of redemption
of Securities of that series to be redeemed and ending at the close of
business on (A) if Securities of the series are issuable only as Registered
Securities, the day of the mailing of the relevant notice of redemption and
(B) if Securities of the series are issuable as Bearer Securities, the day of
the first publication of the relevant notice of redemption, or if Securities
of the series are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, 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 any
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 that series and like tenor, provided that
such Registered Security shall be simultaneously surrendered for redemption.

                                      26
<Page>

         Notwithstanding the foregoing and except as otherwise specified or
contemplated by SECTION 3.01, any Book-Entry Security shall be exchangeable
pursuant to this SECTION 3.05 or SECTIONS 3.04, 9.06 and 11.07 for Securities
registered in the name of, and a transfer of a Book-Entry Security of any series
may be registered to, any Person other than the Depository for such Security or
its nominee only if (i) such Depository notifies the Company that it is
unwilling or unable to continue as Depository for such Book-Entry Security or if
at any time such Depository ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (ii) the Company executes and
delivers to the Trustee a Company Order that such Book-Entry Security shall be
so exchangeable and the transfer thereof so registrable or (iii) there shall
have occurred and be continuing an Event of Default, with respect to the
Securities of such series. Upon the occurrence in respect of any Book-Entry
Security of any series of any one or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be
specified, such Book- Entry Security may be exchanged for Securities registered
in the names of, and the transfer of such Book-Entry Security may be registered
to, such Persons (including Persons other than the Depository with respect to
such series and its nominees) as such Depository shall direct. Notwithstanding
any other provision of this Indenture, any Security authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu of, any Book-
Entry Security shall also be a Book-Entry Security and shall bear the legend
specified in SECTION 2.04 except for any Security authenticated and delivered in
exchange for, or upon registration of transfer of, a Book-Entry Security
pursuant to the preceding sentence.

SECTION 3.06  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES AND COUPONS.

         If any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security or
coupon and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen coupon appertains.

         In case any such mutilated, destroyed, lost or stolen Security or
coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security or coupon
(without surrender thereof except in the case of a mutilated Security or
coupon); PROVIDED, HOWEVER, that the principal of and any premium and interest
on

                                      27
<Page>

Bearer Securities shall, except as otherwise provided in SECTION 10.02, be
payable only at an office or agency located outside the United States.

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

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security or in
exchange for a 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 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 Security and coupons, if any, shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, duly issued
hereunder.

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

SECTION 3.07  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Unless otherwise provided as contemplated by SECTION 3.01 with respect
to any series of Securities, 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 Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest. Unless otherwise so provided, at the option of
the Company, payment of interest on any Registered Security may be made by check
mailed on or before the due date to the address of the Person entitled thereto
as such address shall appear in the Security Register.

         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
Holder on the relevant Regular Record Date by virtue of 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 equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be


                                      28
<Page>

held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this Clause provided. Thereupon the Trustee shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be not more than 15
days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each Holder of Registered
Securities of such series at the address of such Holder as it appears in the
Security Register, not less than 10 days prior to such Special Record Date. The
Trustee shall, in the name and at the expense of the Company, cause a similar
notice to be published at least once in an Authorized Newspaper, provided
such publication shall not be a condition precedent to the establishment of
such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such
Defaulted Interest shall be paid 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).

                  (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 such
Securities may be then 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 and SECTION 3.05,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

SECTION 3.08  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to SECTIONS 3.05 and 3.07) any
interest on such Registered Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. 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 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 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.


                                      29
<Page>

         Notwithstanding the foregoing, with respect to any Book-Entry Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository (or its nominee) as Holder of such Book-Entry Security.

SECTION 3.09  CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
registration of transfer or for credit against any sinking fund payment shall,
if surrendered to any Person other than the Trustee, be delivered to the
Trustee. All Registered Securities and matured coupons so delivered shall be
promptly cancelled by the Trustee. All Bearer Securities and unmatured coupons
so delivered shall be held by the Trustee and, upon instruction by a Company
Order, shall be cancelled or held for reissuance. Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor or the related coupons pursuant to SECTION 3.06. All Bearer
Securities and unmatured coupons held by the Trustee pending such cancellation
or reissuance shall be deemed to be delivered for all purposes of this
Indenture and the Securities. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and
may deliver to the Trustee (or to any other Person for delivery to the
Trustee) for cancellation any Securities previously authenticated hereunder
which the Company has not issued and sold, and all Securities so delivered
shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Securities and coupons held by the Trustee shall be disposed of in
accordance with its customary practice.

SECTION 3.10  COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by SECTION 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.11 CUSIP NUMBERS.

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

                                   ARTICLE IV.
                           SATISFACTION AND DISCHARGE

SECTION 4.01  SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Company Request cease to be of further effect
with respect to Securities of a Series (except as to any surviving rights of
registration of transfer or exchange of Securities herein expressly provided
for, and any right to receive additional amounts, as provided in SECTION 10.04),
and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to
Securities of a Series, when

                  (1)      either


                                      30

Securities and coupons which have been destroyed, lost or stolen and which
have been replaced or paid as provided in SECTION 3.06, (iii) coupons
appertaining to Securities called for redemption and maturing after the
relevant Redemption Date, whose surrender has been waived as provided in
SECTION 11.06, and (iv) Securities and coupons for whose payment money has
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 10.03) have been delivered to the Trustee for
cancellation; or

                           (B)      with respect to all such Securities and, in
the case of (i) or (ii) below, any coupons appertaining thereto not theretofore
delivered to the Trustee for cancellation

                                    (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 (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for the purpose
an amount sufficient to pay and discharge the entire indebtedness on such
Securities and coupons not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and any interest to the date
of such deposit (in the case of Securities which have become due and payable) or
to the Stated Maturity or Redemption Date, as the case may be;

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

                  (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 6.07, the obligations of
the Company to any Authenticating Agent under SECTION 6.14 and, if money shall
have been deposited with the Trustee pursuant to CLAUSE (1)(B) of this Section,
the obligations of the Company under SECTIONS 3.06, 6.10(e) and 7.01 and the
obligations of the Trustee under SECTION 4.02 and the last paragraph of SECTION
10.03 shall survive.

SECTION 4.02  APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of SECTION 10.03, all
money deposited with the Trustee pursuant to SECTION 4.01 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
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 any
premium and interest for whose payment such money has been deposited.

                                   ARTICLE V.
                                    REMEDIES

SECTION 5.01  EVENTS OF DEFAULT.

         "EVENT OF DEFAULT," wherever used herein with respect to Securities of

to any judgment, decree or order, rule or regulation of any administrative or
governmental body), unless it is either inapplicable to a particular series of
Securities or it is specifically deleted or modified in or pursuant to the terms
of such series or in the form of Security of such series:

                  (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 series of Securities other than that
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 33% in
principal amount of the Outstanding Securities of that series a written notice
specifying such default or breach and requiring it to be remedied and stating
that such notice is a "NOTICE OF DEFAULT" hereunder; or

                  (5)      the entry by a court having jurisdiction in the

insolvency, reorganization or other similar law or (B) a decree or order

petition seeking reorganization, arrangement, adjustment or composition of or in
respect of the Company under any applicable Federal or state law, or appointing

similar official of the Company or of any


                                      32
<Page>

substantial part of the property of the Company, 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

                  (6)      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 the commencement of any bankruptcy or
insolvency case or proceeding against the Company, or the filing by the Company
of a petition or answer or consent seeking reorganization or relief under any
applicable Federal or state law, or the consent by the Company to the filing of
such petition or to the appointment of or taking possession by a custodian,

Company or of any substantial part of the property of the Company, or the making
by the Company of an assignment for the benefit of creditors, or the admission
by the Company 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

                  (7)      any other Event of Default provided with respect to
Securities of that series.

SECTION 5.02 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 33% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
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 Securities of that 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 interest on, and any additional
amounts payable as set forth in SECTION 10.04 on, all Securities of that series
and any coupons appertaining thereto,

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


                                      33
<Page>


                           (C)      to the extent that payment of such
interest is lawful, interest upon overdue interest, and any additional
amounts payable as set forth in SECTION 10.04 on, at the rate or rates
prescribed therefor in such 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 Securities
of that series, other than the non-payment of the principal of Securities of
that series which have become due solely by such declaration of acceleration,
have been cured or waived as provided in SECTION 5.13.

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

SECTION 5.03  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

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

                  (2)      default is made in the payment of the principal of
(or premium, if any, on) any Security at the Maturity thereof, the Company
will, upon demand of the Trustee, pay to it, for the benefit of the Holders
of such Securities and coupons, the whole amount then due and payable on such
Securities and coupons for principal and any premium and interest and, to the
extent that payment of such interest shall be legally enforceable, interest
on any overdue principal and premium and on any overdue interest, at the rate
or rates prescribed therefor in such Securities (or, in the case of Original
Issue Discount Securities, the Securities' yield to maturity) 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, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such
Securities 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 Securities, wherever situated.

         If an Event of Default with respect to 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 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 Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy.


                                       34
<Page>

SECTION 5.04  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), or the property or the creditors of the
Company, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the
Trust Indenture Act in order to have claims of the Holders and the Trustee
allowed in any such proceeding. In particular, subject to ARTICLE FIFTEEN
hereof, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under SECTION
6.07.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding;
PROVIDED, HOWEVER, that the Trustee may, on behalf of Holders, vote for the
election of a trustee of bankruptcy or similar official and be a member of a
creditors' or other similar committee.

SECTION 5.05  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES OR
COUPONS.

         All rights of action and claims under this Indenture or the
Securities or coupons may be prosecuted and enforced by the Trustee without
the possession of any of the 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 reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

SECTION 5.06  APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal or any
premium or interest, upon presentation of the Securities or 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
6.07; and

         SECOND: Subject to ARTICLE FIFTEEN hereof, to the payment of the
amounts then due and unpaid for principal of and any premium and interest on the
Securities and coupons in respect of which or for the benefit of which such
money has been collected, ratably, without

                                       35

<Page>

preference or priority of any kind, according to the amounts due and payable
on such Securities and coupons for principal and any premium and interest,
respectively.

         THIRD: The balance, if any, to the Person or Persons entitled
thereto.

         In any case in which Securities are Outstanding that are denominated
in more than one currency and the Trustee is directed to make ratable
payments under this Section to Holders of such Securities, unless otherwise
provided with respect to any series of Securities, the Trustee shall
calculate the amount of such payments as follows: (i) as of the day the
Trustee collects an amount under this Article, the Trustee shall, as to each
Holder of a Security to whom an amount is due and payable under this Section
that is denominated in a foreign currency, determine that amount in Dollars
that would be obtained for the amount owing such Holder, using the rate of
exchange at which in accordance with normal banking procedures the Trustee
could purchase in The City of New York Dollars with such amount owing; (ii)
calculate the sum of all Dollar amounts determined under (i) and add thereto
any amounts due and payable in Dollars; and (iii) using the individual
amounts determined in (i) or any individual amounts due and payable in
Dollars, as the case may be, as a numerator, and the sum calculated in (ii)
as a denominator, calculate as to each Holder of a Security to whom an amount
is owed under this Section the fraction of the amount collected under this
Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities denominated in a
currency other than that in which any amount is collected under this Article
shall be likewise (in accordance with this paragraph) borne ratably by all
Holders of Securities to whom amounts are payable under this Section.

         To the fullest extent allowed under applicable law, if for the
purpose of obtaining judgment against the Company in any court it is
necessary to convert the sum due in respect of the principal of, or premium,
if any, or interest on, the Securities of any series (the "REQUIRED
CURRENCY") into a currency in which a judgment will be rendered (the
"JUDGMENT CURRENCY"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the
Business Day in the City of New York next preceding that on which final
judgment is given. Neither the Company nor the Trustee shall be liable for
any shortfall nor shall it benefit from any windfall in payments to Holders
of Securities under this Section caused by a change in exchange rates between
the time the amount of a judgment against the Company is calculated as above
and the time the Trustee converts the Judgment Currency into the Required
Currency to make payments under this Section to Holders of Securities, but
payment of such judgment shall discharge all amounts owed by the Company on
the claim or claims underlying such judgment.

SECTION 5.07  LIMITATION ON SUITS.

         No Holder of any Security 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 Securities
of that series;


                                       36
<Page>


                  (2)      the Holders of not less than 33% in principal
amount of the Outstanding Securities of that 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

                  (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 Securities of
that 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 of 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 such Holders.

SECTION 5.08  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
INTEREST.

         Notwithstanding any other provision in this Indenture (but subject to
ARTICLE FIFTEEN hereof), the Holder of any Security or coupon shall have the
right, which is absolute and unconditional, to receive payment of the
principal of and any premium and (subject to SECTIONS 3.05 and 3.07) any
interest on such Security or payment of such coupon on the Stated Maturity or
Maturities expressed in such Security or coupon (or, in the case of
redemption, on the Redemption Date), and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

SECTION 5.09  RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 5.10  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons in the
last paragraph of SECTION 3.06, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or coupons 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


                                       37
<Page>

remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any
other appropriate right or remedy.

SECTION 5.11  DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security
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 of Securities or
coupons may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.

SECTION 5.12  CONTROL BY HOLDERS OF SECURITIES.

         The Holders of a majority in principal amount of the Outstanding
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 Securities of such series, provided that

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

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

                  (3)      the Trustee shall not be obligated to take any
action unduly prejudicial to Holders not joining in such direction or
involving the Trustee in personal liability.

SECTION 5.13  WAIVER OF PAST DEFAULTS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities
of such series waive any past default hereunder with respect to the
Securities of such series and its consequences, except a default

                  (1)      in the payment of the principal of or any premium
or interest on any 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 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.


                                       38
<Page>

SECTION 5.14  UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered
or omitted by it as Trustee, a court may require any party litigant in such
suit to file an undertaking to pay the costs of such suit, including legal
fees and expenses, and may assess costs against any such party litigant, in
the manner and to the extent provided in the Trust Indenture Act; provided
that neither this Section nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Trustee or the Company.

SECTION 5.15  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 to take the benefit or advantage of, any stay or extension
law wherever enacted, now or at any time hereafter in force, which may affect
the covenants or the performance of this Indenture; and the Company (to the
extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had
been enacted.

                                   ARTICLE VI.
                                   THE TRUSTEE

SECTION 6.01  CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided
by the Trust Indenture Act. Notwithstanding the foregoing, no provision of
this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured
to it. Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

SECTION 6.02  NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of 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 5.01(4) with respect to 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 Securities of such series.

SECTION 6.03  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of SECTION 6.01:

(unless other evidence be herein specifically prescribed) may, in the absence
of bad faith on its part, rely upon an Officers' Certificate;

                  (4)      the Trustee may consult with counsel of its

SECTION 6.05  MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or
any other capacity, may become the owner or pledgee of Securities and coupons

with the same rights it would have if it were not Trustee, Authenticating
Agent, Paying Agent, Security Registrar or such other agent.

SECTION 6.06  MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated

SECTION 6.07  COMPENSATION AND REIMBURSEMENT.

         The Company agrees

                  (1)      to pay to the Trustee from time to time such

for all services rendered by it hereunder (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of
an express trust);

                  (2)      except as otherwise expressly provided herein, to
reimburse the Trustee and each predecessor 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

                  (3)      to indemnify the Trustee and each predecessor
Trustee for, and to hold it harmless against any and all loss, liability,
damage, claim or expense, including taxes (other than taxes based on the income

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, a Holder or any other Person) or
liability in connection with the exercise or performance of any of its powers
or duties hereunder.

         The obligations of the Company under this Section shall not be
subordinated to the payment of Senior Indebtedness pursuant to ARTICLE
FIFTEEN hereof, and as security for the performance of such obligations, the
Trustee shall have a lien prior to the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the Holders of particular Securities.

         Any expenses and compensation for any services rendered by the

SECTION 6.08  DISQUALIFICATION; CONFLICTING INTERESTS.

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

SECTION 6.09  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder which shall be a
corporation 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, subject to supervision or examination by Federal or state
authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined
capital and surplus of such 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. No
obligor upon any Security issued under this Indenture or a person directly or
indirectly controlling, controlled by or under common control with such
obligor shall serve as Trustee under this Indenture.

SECTION 6.10  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a)      No resignation or removal of the Trustee and no appointment
of a successor Trustee pursuant to this Article shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of SECTION 6.11.

         (b)      The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
SECTION 6.11 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 Securities of
such series.

         (c)      The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series delivered to the Trustee
and to the Company. If the instrument of acceptance by a successor Trustee
required by SECTION 6.11 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
Securities of such series.

         (d)      If at any time:

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

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


                                       42
<Page>

                  (3)      the Trustee shall become incapable of acting or
shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
its property shall be appointed or a public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, then, in any case, (i) the
Company by a Board Resolution may remove the Trustee with respect to all
Securities, or (ii) subject to SECTION 5.14, any Holder of a Security who has
been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities
and the appointment of a successor Trustee or Trustees.

         (e)      If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of the Trustee for any
cause, with respect to the Securities of one or more series, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood
that any such successor Trustee may be appointed with respect to the
Securities of one or more or all series and that at any time there shall be
only one Trustee with respect to the Securities of any particular series) and
shall comply with the applicable requirements of SECTION 6.11. If, within one
year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee with respect to the Securities of any
series shall be appointed by Act of the Holders of a majority in principal
amount of the Outstanding 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 in accordance with the applicable
requirements of SECTION 6.11, become the successor Trustee with respect to
the Securities of such series and to that extent supersede the successor
Trustee appointed by the Company. If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Company or the
Holders of Securities of such series and accepted appointment in the manner
required by SECTION 6.11, any Holder of a Security who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series. Such court may thereupon, after such notice, if
any, as it may deem proper, appoint a successor Trustee.

         (f)      The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any
series in the manner provided in SECTION 1.06. Each notice shall include the
name of the successor Trustee with respect to the Securities of such series
and the address of its Corporate Trust Office.

SECTION 6.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)      In case of the appointment hereunder of a successor Trustee
with respect to all 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 further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring
Trustee, with like effect as if originally named Trustee hereunder; but on
the request of the Company or the successor Trustee, such retiring


                                       43
<Page>

Trustee shall, upon payment of its charges, 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. Any Trustee ceasing to act shall, nevertheless, retain a prior
lien upon all property or funds held or collected by such Trustee to secure
any amounts then due it pursuant to the provisions of SECTION 6.07.

         (b)      In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture 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 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 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 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 as 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
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on 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 Securities of that or those series to which the appointment of
such successor Trustee relates.

         (c)      Upon request of any 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 6.12  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided


                                       44
<Page>

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

SECTION 6.13  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

SECTION 6.14  APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may, by an instrument in writing, appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which may be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue or upon exchange, registration of transfer or
partial redemption thereof or pursuant to SECTION 3.06, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States, any State thereof or the District of Columbia (or, if Bearer Securities,
organized and doing business under the laws of the country in which the Bearer
Securities are eligible), authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state authority (or, if
Bearer Securities, an authority of the country in which the Bearer Securities
are eligible). If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

                                       45
<Page>

         An Authenticating Agent may, and if it shall cease to be eligible
shall, resign at any time by giving written notice thereof to the Trustee and to
the Company. The Trustee may at any time terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company. Upon receiving such notice of resignation or upon such
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Registered Securities, if any, of the series
with respect to which such Authenticating Agent will serve, as their names and
addresses appear in the Security Register. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers, and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

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

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have been endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

         "This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.


                                     BNY Midwest Trust Company,
                                     As Trustee


                                     By:________________________________________
                                        As Authenticating Agent


                                     By:________________________________________
                                        Authorized Officer

         If all the Securities of a series may not be originally issued at one
time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which
writing need not comply with SECTION 1.02 and need not be accompanied by an
Opinion of Counsel), shall appoint in accordance with this Section an
Authenticating Agent (which, if so requested by the Company, shall be such
Affiliate of the Company) having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

with respect to their rights under this Indenture or under the Securities, and
the corresponding rights and privileges of the Trustee, shall be as provided by
the Trust Indenture Act.

         (c)      Every Holder of Securities or coupons, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any agent of any of them shall be held accountable

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

compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

                                  ARTICLE VIII.

                  (5)      to add to, change or eliminate any of the provisions
of this Indenture in respect of one or more series of Securities, provided that

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 6.11(b); or

                  (8)      to cure any ambiguity, to correct or supplement any
provision herein or in any supplemental indenture which may be defective or
inconsistent with any other provision herein or in any supplemental indenture,
or to make any other provisions with respect to matters or questions arising

affect the interests of the Holders of Securities of any series or any related
coupons in any material respect.

other provision of this Indenture which has expressly been included solely for

Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders of 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 9.07  SUBORDINATION UNIMPAIRED.

         This Indenture may not be amended to alter the subordination of any

                                   ARTICLE X.
                                   COVENANTS

SECTION 10.01 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by SECTION 3.01 with respect to any series
of Securities, any interest due on Bearer Securities on or before Maturity shall
be payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature.

SECTION 10.02 CORPORATE EXISTENCE AND MAINTENANCE OF OFFICE OR AGENCY.

         Except as expressly permitted by this Indenture, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect the corporate existence of the Company.

         If Securities of a series are issuable only as Registered Securities,
the Company will maintain in each Place of Payment for such series an office
or agency where Securities of that series may be presented or surrendered for
payment where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company will
maintain (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may
be surrendered for exchange, where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served
and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment in the circumstances described in the
following paragraph

                                       52
<Page>

(and not otherwise), (B) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where Securities of that series and related
coupons may be presented and surrendered for payment (including payment of any
additional amounts payable on Securities of that series pursuant to SECTION
10.04); PROVIDED, HOWEVER, that if the Securities of that series are listed on
The International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require,
the Company will maintain a Paying Agent for the Securities of that series in
London, Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of that series are
listed on such exchange, and (C) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States an office or agency where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for exchange and where notices and demands to
or upon the Company in respect of the Securities of that series, and this
Indenture may be served. The Company will give prompt written notice to the
Trustee and prompt notices to the Holders as provided in SECTION 1.06 of the
location, and any change in the location, of any such office or agency. If at
any time the Company shall fail to maintain any such required office or agency
in respect of any series of Securities or shall fail to furnish the Trustee
with the address thereof, such presentations and surrenders of Securities of
that series may be made and notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment
(including payment of any additional amounts payable on Bearer Securities of
that series pursuant to SECTION 10.04) at any Paying Agent for such series
located outside the United States, and the Company hereby appoints the same as
its agents to receive such respective presentations, surrenders, notices and
demands.

         No payment of principal, premium 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, that, if
the Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to SECTION
10.04) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, premium, interest or additional amounts, as the
case may be, at all offices or agencies 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.

         The Company may also from time to time designate one or more other
offices or agencies where Securities of one or more series 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 accordance with the requirements set forth above for Securities of any series
for such purposes. The Company will give prompt written notice to the Trustee
and the Holders of any such designation or rescission and of any other change in
the location of any such other office or agency.

SECTION 10.03 MONEY FOR 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 Securities and any coupons appertaining thereto, it
will, on or before each due date of the principal of and any premium or interest
on any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal
and any premium 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 to so act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
and any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal and any premium 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 to so act.

         The Company will cause each Paying Agent for any series of Securities
(other than the Company or 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 (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture 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 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 any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal and any premium or interest has become due and payable
shall be paid to the Company on Company Request (unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law), or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Security or any coupon appertaining thereto shall (unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property law) 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, 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 in each Place


                                       54
<Page>

of Payment, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

SECTION 10.04 ADDITIONAL AMOUNTS.

         If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein. Whenever
in this Indenture there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Security of
any series or payment of any related coupon or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of additional amounts provided for in 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 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 Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium 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 any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the 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 Securities or coupons and the Company will
pay to the Trustee or such Paying Agent the additional amounts required by 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 10.05 PURCHASE OF SECURITIES BY COMPANY OR SUBSIDIARY.

         If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and will
not permit any of its Subsidiaries to, purchase any Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the Securities of that
series as shown in The Stock Exchange Daily Official List for the last trading
day preceding the date of purchase.

         The Company, whenever necessary to avoid or fill a vacancy in the
office of the Trustee, will appoint, in the manner provided in SECTION 6.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

SECTION 10.07 STATEMENT BY OFFICER AS TO DEFAULT.

         (a) The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture. For purposes
of this SECTION 10.07, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture. Such certificate
shall comply with Section 314(a)(4) of the Trust Indenture Act.

         (b) The Company shall, so long as any of the Securities are
outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of
any Event of Default or event which, after notice or lapse of time or both,
would become an Event of Default, an Officers' Certificate specifying such Event
of Default or event and what action the Company proposes to take with respect
thereto.

SECTION 10.08 WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in SECTION 10.05 with respect to the
Securities of any series if before the time for such compliance the Holders of a
majority in principal amount of the Outstanding Securities of such series shall,
by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision 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
term, provision or condition shall remain in full force and effect.

SECTION 10.09 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
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 XI.
                            REDEMPTION OF SECURITIES

SECTION 11.01 APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable before their Stated

otherwise specified as contemplated by SECTION 3.01 for Securities of any
series) in accordance with this Article.

SECTION 11.02 ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. In the case of any redemption at the election of the
Company of the Securities of any series, the Company shall, at least 45 days
prior to the Redemption Date fixed


                                       56
<Page>

by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date, of the principal amount
of Securities of such series to be redeemed and, if applicable, of the tenor
of the Securities of such series to be redeemed. In the case of any
redemption of Securities (i) prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this
Indenture, or (ii) pursuant to an election of the Company which is subject to
a condition specified in the terms of such Securities, the Company shall
furnish the Trustee with an Officers' Certificate evidencing compliance with
such restriction or condition.

SECTION 11.03 SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series of a specified tenor are to be
redeemed) the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series 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 Securities of that series or any integral multiple thereof) of
the principal amount of Registered Securities of such series of a denomination
larger than the minimum authorized denomination for Securities of that series or
of the principal amount of global Securities of such series. If less than all of
the Securities of such series and of a specified tenor are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in
accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any 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 Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 11.04 NOTICE OF REDEMPTION.

         Notice of redemption shall be given in the manner provided in SECTION
1.06 to the Holders of Securities to be redeemed not less than 30 nor more than

                  (2)      the Redemption Price,

                  (3)      if less than all the Outstanding Securities of any
series are to be redeemed, the identification (and, in the case of partial
redemption of any Securities, the principal amounts) of the particular
Securities to be redeemed, and that on and after the Redemption Date, upon
surrender of the Securities, new Securities of such series in principal amount
equal to the unredeemed part thereof will be issued,

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

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

                  (6)      that the redemption is for a sinking fund, if such is
the case.

         A notice of redemption published as contemplated by SECTION 1.06 need
not identify particular Registered Securities to be redeemed.

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 11.05 DEPOSIT OF REDEMPTION PRICE.

         On or prior to 10:00 a.m., New York City time, on 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 10.03) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be
redeemed on that date.

SECTION 11.06  SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein


                                       58

specified, and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued interest) such 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 Security for redemption in
accordance with said notice, together with all coupons, if any, appertaining
thereto maturing after the Redemption Date, such 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 at an office or agency located outside the United States
(except as otherwise provided in SECTION 10.02) and, unless otherwise
specified as contemplated by SECTION 3.01, only upon presentation and
surrender of coupons for such interest, and PROVIDED, FURTHER, that, unless
otherwise specified as contemplated by SECTION 3.01, 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 Securities, or one or
more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of
SECTION 3.07.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
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 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; 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 10.02) and, unless otherwise specified as contemplated by SECTION 3.01,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security or, in the case of Original Issue Discount Securities, the
Securities' yield to maturity.

SECTION 11.07 SECURITIES REDEEMED IN PART.

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

                                  SINKING FUNDS

SECTION 12.01 APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by SECTION 3.01 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of 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 Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in SECTION 12.02. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 12.02 SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company (1) may deliver Outstanding 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 Securities of a series which have been redeemed
either at the election of the Company pursuant to the terms of such Securities
or through the application of permitted optional sinking fund payments
pursuant to the terms of such Securities, in each case in satisfaction of all
or any part of any sinking fund payment with respect to the Securities of such
series required to be made pursuant to the terms of such Securities as
provided for by the terms of such series; provided that such Securities have
not been previously so credited. Such Securities shall be received and
credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such sinking fund payment shall be reduced accordingly.

SECTION 12.03 REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
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 and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
SECTION 12.02 and will also deliver to the Trustee any Securities to be so
credited. Not less than 45 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in SECTION 11.03 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 11.04. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in SECTIONS 11.06 and 11.07.

condition or limitation set forth in any such Section or clause whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or
clause or by reason of any reference in any such Section or clause to any other

caused to be deposited with the Trustee (or another trustee satisfying the
requirements of SECTION 6.09 who shall agree to comply with the provisions of
this ARTICLE THIRTEEN applicable to it) as trust funds in trust for the purpose
of making the following payments specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of the Securities of such
series, (A) money in an amount, or (B) U.S. Government Obligations which through
the scheduled payment of principal and interest in respect thereof in accordance
with their terms will provide, not later than one day before the due date of any
payment, money in an amount, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, the principal of (and premium, if any) and each
installment of interest on the Securities and any coupons pertaining thereto on
the Stated Maturity of such principal (and premium, if any) or installment of
interest in accordance with the terms of this Indenture and of the Securities of

Government Obligation or a specific payment of principal of or interest on any
such U.S. Government Obligation held by such custodian for the account of the
holder of such depository receipt, provided that (except as required by law)
such custodian is not authorized to make any deduction from the amount payable
to the holder of such depository receipt from any amount received by the
custodian in respect of the U.S. Government Obligation or the specific payment
of principal of or interest on the U.S. Government Obligation evidenced by such
depository receipt.

                  (2)      In the case of an election under SECTION 13.02, the
Company shall have delivered to the Trustee an Opinion of Counsel stating that
(x) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling, or (y) since the date of this Indenture there has been
a change in the applicable United States Federal income tax law, in either case
to the effect that, and based thereon such opinion shall confirm that, the
Holders of the Outstanding Securities of such series will not recognize income,
gain or loss for United States Federal income tax purposes as a result of such
deposit, defeasance and discharge and will be subject to United States Federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such deposit, defeasance and discharge had not
occurred.

                  (3)      In the case of an election under SECTION 13.03, the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of the Outstanding Securities of such series will not recognize
gain or loss for United States Federal income tax purposes as a result of such
deposit and covenant defeasance and will be subject to United States Federal
income tax on the same amount, in the same manner and at the same times as would
have been the case if such deposit and covenant defeasance had not occurred.

                  (4)      No Event of Default or event which with notice or
lapse of time or both would become an Event of Default with respect to the
Securities of such series shall have occurred and be continuing on the date of
such deposit or, insofar as SECTIONS 5.01(5) and (6) are concerned, at any time
during the period ending on the 121st day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until the
expiration of such period).

                  (5)      Such defeasance or covenant defeasance shall not
cause the Trustee to have a conflicting interest within the meaning of the Trust
Indenture Act with respect to any securities of the Company.

                  (6)      Such defeasance or covenant defeasance shall not
result in a breach or violation of, or constitute a default under, any other
agreement or instrument to which the Company is a party or by which it is bound.

                  (7)      The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for relating to either the defeasance under
SECTION 13.02 or the covenant defeasance under SECTION 13.03 (as the case may
be) have been complied with.

                  (8)      Such defeasance or covenant defeasance shall not
result in the trust arising from such deposit constituting an investment company
as defined in the Investment Company Act of 1940, as amended, or such trust
shall be qualified under such Act or exempt from regulation thereunder.

SECTION 13.05 DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of SECTION 10.03, all

with the Trustee (or other qualifying trustee -- collectively, for purposes of
this SECTION 13.05, the "TRUSTEE") pursuant to SECTION 13.04 in respect of the
Securities of such series shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities of such series 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 Holders of the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to SECTION 13.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

         Anything in this ARTICLE THIRTEEN to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
SECTION 13.04 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification


                                       63
<Page>

thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect an equivalent defeasance or
covenant defeasance.

SECTION 13.06 REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with SECTION 13.02 or 13.03 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Indenture and the Securities of such series shall be revived and reinstated
as though no deposit had occurred pursuant to this ARTICLE THIRTEEN until
such time as the Trustee or Paying Agent is permitted to apply all such money
in accordance with SECTION 13.02 or 13.03; PROVIDED, HOWEVER, that if the
Company makes any payment of principal of or any premium or interest on any
Security following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of the Securities of such series to
receive such payment from the money held by the Trustee or the Paying Agent.

                                  ARTICLE XIV.

proof specified in SECTION 1.04 or other proof.

         (b)      The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called
by the Company or by Holders of Bearer Securities as provided in SECTION

Outstanding Securities of such series held or represented by him; PROVIDED,
HOWEVER, that no vote shall be cast or counted at any meeting in respect of
any Bearer Security challenged as not Outstanding and ruled by the chairman
of the meeting to be not Outstanding. The chairman of the meeting shall have

delivered to the Company, and another to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the

                                  ARTICLE XV.
                                  SUBORDINATION

SECTION 15.01 SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         The Company covenants and agrees that anything in this Indenture to
the contrary notwithstanding, the indebtedness evidenced by the Securities of
each series is subordinate and junior in right of payment to all Senior
Indebtedness to the extent provided herein or, if so provided in a Board
Resolution, Officers' Certificate or executed supplemental indenture referred
to in SECTIONS 2.01 and 3.01 by or pursuant to which the form and terms of
the Securities of such series were established, as and to the extent provided
by the terms of the Securities of such series, and each Holder of Securities
of each series, by his acceptance thereof, likewise covenants and agrees to
the subordination herein or therein provided and shall be bound by the
provisions hereof or thereof.

         This ARTICLE FIFTEEN shall constitute a continuing offer to all
Persons who, in reliance upon such provisions, become holders of, or continue
to hold, Senior Indebtedness, and such provisions are made for the benefit of
the holders of Senior Indebtedness, and such holders are made obligees
hereunder and any one or more of them may enforce such provisions.

         No payment may be made by the Company on account of the principal of
or any premium or interest on the Securities, or to acquire any of the
Securities (including repurchases of Securities at the option of the Holders)
for cash or property (other than Junior Securities), or on account of any
redemption provisions of the Securities, (i) upon the maturity of any Senior
Indebtedness of the Company by lapse of time, acceleration (unless waived) or
otherwise, unless and until all principal of and any premium and interest on
such Senior Indebtedness are first paid in full (or such payment is duly
provided for) or (ii) in the event of a default in the payment of any
principal of or any premium or interest on any Senior Indebtedness when it
becomes due and payable, whether at stated maturity or at a date fixed for
prepayment or by declaration or otherwise (a "PAYMENT DEFAULT"), unless and
until such Payment Default has been cured or waived or otherwise has ceased
to exist.

         Upon (i) the happening of an event of default (other than a Payment
Default) that permits the holders of Senior Indebtedness or their
representative immediately to accelerate its maturity, and (ii) written
notice of such event of default given to the Company and the Trustee by the
holders of at least 33% in aggregate principal amount outstanding of such
Senior Indebtedness or their representative (a "PAYMENT NOTICE"), then,
unless and until such event of default has been cured or waived or otherwise
has ceased to exist, no payment (by set off or otherwise) may be made by or
on behalf of the Company on account of the principal of or any premium or
interest on the Securities, or to acquire or repurchase any of the Securities
for cash or property, or on account of any redemption provisions of the
Securities, in any such case other than payments made with Junior Securities
of the Company. Notwithstanding the foregoing, unless (i) the Senior
Indebtedness in respect of which such event of default exists has been
declared due and payable in its entirety within 179 days after the Payment
Notice is delivered as set forth above (the "PAYMENT BLOCKAGE PERIOD"), and
(ii) such declaration has not been rescinded or waived, at the end of the
Payment Blockage Period, the Company shall be required to pay all sums not
paid to the Holders of the Securities during the Payment Blockage Period due
to the foregoing prohibitions and to resume all other payments as and when
due on the Securities. Any number of Payment Notices may be given; PROVIDED,
HOWEVER, that (i) not more than one Payment Notice shall be given within a
period of any 360 consecutive days, and (ii) no event of default that existed
upon the date of such Payment Notice or the commencement of such Payment
Blockage Period (whether or not such event of default is on the same issue of
Senior Indebtedness) shall be made the basis for the commencement of any
other Payment Blockage Period.

                                      67

         Upon any distribution of assets of the Company upon any dissolution,
winding-up, liquidation or reorganization, whether voluntary of involuntary,
in bankruptcy, insolvency, receivership or a similar proceeding or upon
assignment for the benefit of creditors or any marshaling of assets or
liabilities: (i) the holders of all Senior Indebtedness shall first be
entitled to receive payments in full (or have such payment duly provided for)
before the Holders are entitled to receive any payment on account of the
principal of or any premium or interest on the Securities (other than Junior
Securities); and (ii) any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities (other than
Junior Securities), to which the Holders or the Trustee on behalf of the
Holders would be entitled (by set off or otherwise), except for the
provisions of this ARTICLE FIFTEEN, shall be paid by the liquidating trustee
or agent or other Person making such a payment or distribution directly to
the holders of Senior Indebtedness or their representative to the extent
necessary to make payment in full of all such Senior Indebtedness remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness.

         In the event that, notwithstanding the foregoing provisions of this
SECTION 15.01, any payment or distribution of assets of the Company (other
than Junior Securities) shall be received by the Trustee or the Holders at a
time when such payment or distribution is prohibited by the provisions of
this SECTION 15.01, then such payment or distribution (subject to the
provisions of SECTION 15.03 shall be received and held in trust by the
Trustee or such Holders for the benefit of the holders of Senior
Indebtedness, and shall be paid or delivered by the Trustee or such Holders,
as the case may be, to the holders of Senior Indebtedness remaining unpaid or
unprovided for, or their representative or representatives, or to the trustee
or trustees under any indenture pursuant to which any instruments evidencing
any of such Senior Indebtedness may have been issued, ratably according to
the aggregate amounts remaining unpaid on account of the Senior Indebtedness
held or represented by each, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay or to provide
for the payment of all such Senior Indebtedness in full after giving effect
to any concurrent payment and distribution to the holders of such Senior
Indebtedness.

         The failure to make a payment on account of principal of or any
premium or interest on the Securities of any series by reason of any
provision of this ARTICLE FIFTEEN shall not be construed as preventing the
occurrence of an Event of Default. Nothing contained herein shall impair, as
between the Company and the Holders of Securities of each series, the
obligation of the Company, which is absolute and unconditional, to pay to
such Holders the principal of and any premium and interest on such Securities
as and when the same shall become due and payable in accordance with their
terms or prevent the Trustee or any Holder from exercising all rights, powers
and remedies otherwise permitted by applicable law or hereunder upon a
default or Event of Default hereunder, all subject to the rights of the
holders of the Senior Indebtedness to receive cash, securities or other
property otherwise payable or deliverable to the Holders.

         Senior Indebtedness shall not be deemed to have been paid in full
unless the holders thereof shall have received cash, securities or other
property equal to the amount of such Senior Indebtedness then outstanding.
Upon the payment in full of all Senior Indebtedness, the Holders of
Securities of each series shall be subrogated to all rights of any holders of
Senior Indebtedness to receive any further payments or distributions
applicable to the Senior Indebtedness until the indebtedness evidenced by the
Securities of such series shall have been paid in full, and such


                                      68
<Page>

payments or distributions received by such Holders, by reason of such
subrogation, of cash, securities or other property which otherwise would be
paid or distributed to the holders of Senior Indebtedness, shall, as between
the Company and its creditors other than the holders of Senior Indebtedness,
on the one hand, and such Holders, on the other hand, be deemed to be a
payment by the Company on account of Senior Indebtedness, and not on account
of the Securities of such series.

         The provisions of this SECTION 15.01 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in
respect of any security interest the creation of which is not prohibited by
the provisions of this Indenture.

         The securing of any obligations of the Company, otherwise ranking on
a parity with the Securities or ranking junior to the Securities, shall not
be deemed to prevent such obligations from constituting, respectively,
obligations ranking on a parity with the Securities or ranking junior to the
Securities.

SECTION 15.02 RELIANCE ON CERTIFICATE OF LIQUIDATING AGENT; FURTHER EVIDENCE
AS TO OWNERSHIP OF SENIOR INDEBTEDNESS.

         Upon any payment or distribution of assets of the Company, the
Trustee and the Holders shall be entitled to rely upon an order or decree
issued by any court of competent jurisdiction in which such dissolution or
winding-up or liquidation or reorganization proceedings are pending or upon a
certificate of the trustee in bankruptcy, receiver, assignee for the benefit
of creditors or other Person making such payment or distribution, delivered
to the Trustee or to the Holders, for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this ARTICLE FIFTEEN. In the absence of
any such bankruptcy trustee, receiver, assignee or other Person, the Trustee
shall be entitled to rely upon a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee or representative
on behalf of such holder) as evidence that such Person is a holder of Senior
Indebtedness (or is such a trustee or representative). If the Trustee
determines, in good faith, that further evidence is required with respect to
the right of any Person as a holder of Senior Indebtedness to participate in
any payment or distribution pursuant to this ARTICLE FIFTEEN, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness held by such Person, as to
the extent to which such Person is entitled to participate in such payment or
distribution, and as to other facts pertinent to the rights of such Person
under this ARTICLE FIFTEEN, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination
as to the right of such Person to receive such payment.

SECTION 15.03 APPLICATION BY TRUSTEE OF ASSETS DEPOSITED WITH IT.

         Amounts deposited in trust with the Trustee pursuant to and in
accordance with ARTICLE THIRTEEN shall be for the sole benefit of Holders of
Securities of each series subject thereto and, to the extent allocated for
the payment of such Securities, shall not be subject to the subordination
provisions of this ARTICLE FIFTEEN. Otherwise, any deposit of assets with the


                                      69
<Page>

Trustee (whether or not in trust) for the payment of the principal of or any
premium or interest on any Securities shall be subject to the provisions of
this ARTICLE FIFTEEN; PROVIDED, HOWEVER, if prior to one Business Day
preceding the date on which by the terms of this Indenture any such assets
may become distributable for any purpose (including, without limitation, the
payment of the principal of or any premium or interest on any Security) the
Trustee shall not have received with respect to such assets the Officers'
Certificate or written notice provided for in SECTION 15.05, then the Trustee
shall have full power and authority to receive such assets and to apply the
same to the purpose for which they were received.

SECTION 15.04 DISPUTES WITH HOLDERS OF CERTAIN SENIOR INDEBTEDNESS.

         Any failure by the Company to make any payment on or under any
Senior Indebtedness, other than any Senior Indebtedness as to which the
provisions of this SECTION 15.04 shall have been waived by the Company in the
instrument or instruments by which the Company incurred, assumed, guaranteed
or otherwise created such Senior Indebtedness, shall not be deemed a default
under SECTION 15.01 if (i) the Company shall be disputing its obligation to
make such payment or perform such obligation, and (ii) either (A) no final
judgment relating to such dispute shall have been issued against the Company
which is in full force and effect and is not subject to further review,
including a judgment that has become final by reason of the expiration of the
time within which a party may seek further appeal or review, or (B) in the
event of a judgment that is subject to further review or appeal has been
issued, the Company shall in good faith be prosecuting an appeal or other
proceeding for review, and a stay of execution shall have been obtained
pending such appeal or review.

SECTION 15.05 TRUSTEE NOT CHARGED WITH KNOWLEDGE OF PROHIBITION.

         Anything in this ARTICLE FIFTEEN or elsewhere in this Indenture
contained to the contrary notwithstanding, the Trustee shall not at any time
be charged with knowledge of the existence of any facts which would prohibit
the making of any payment of moneys to or by Trustee and shall be entitled to
assume conclusively that no such facts exist, unless and until the Trustee
shall have received an Officers' Certificate to that effect or notice in
writing to that effect signed by or on behalf of the holder or holders, or
their representatives, of Senior Indebtedness who shall have been certified
by the Company or otherwise established to the reasonable satisfaction of the
Trustee to be such holder or holders or representatives or from any trustee
under any indenture pursuant to which such Senior Indebtedness shall be
outstanding; PROVIDED, HOWEVER, that, if the Trustee shall not have received
the Officers' Certificate or notice provided for in this SECTION 15.05 at
least one Business Day preceding the date upon which by the terms hereof any
such moneys may become payable for any purpose (including, without
limitation, the payment of the principal of or any premium or interest on any
Security), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such moneys and
apply the same to the purpose for which they were received and shall not be
affected by any notice to the contrary which may be received by it within one
Business Day preceding such date. The Company shall give prompt written
notice to the Trustee and to each Paying Agent of any facts which would
prohibit any payment of moneys to or by the Trustee or any Paying Agent, and
the Trustee shall not be charged with knowledge of the curing of any default
or the elimination of any other fact or condition preventing such payment or
distribution unless and until the Trustee shall have received an Officers'
Certificate to such effect.

SECTION 15.06 TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of Securities by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as between such Holder and
holders of Senior Indebtedness as provided in this ARTICLE FIFTEEN and
appoints the Trustee its attorney-in-fact for any and all such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Company (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors
of the Company), the immediate filing of a claim for the unpaid balance of
his Securities in the form required in said proceedings and cause said claim
to be approved. If the Trustee does not file a proper claim or proof of debt
in the form required in such proceeding prior to 30 days before the
expiration of the time to file such claim or claims, then the holders of the
Senior Indebtedness or their representative is hereby authorized to have the
right to file and is hereby authorized to file an appropriate claim for and
on behalf of the Holders of said Securities. Nothing herein contained shall
be deemed to authorize the Trustee or the holders of Senior Indebtedness or
their representative to authorize or consent to or accept or adopt on behalf
of any Security holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or
to authorize the Trustee or the holders of Senior Indebtedness or their
representative to vote in respect of the claim of any Security holder in any
such proceeding.

SECTION 15.07 RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS.

         The Trustee shall be entitled to all the rights set forth in this
ARTICLE FIFTEEN with respect to any Senior Indebtedness which may at the time
be held by it, to the same extent as any other holder of Senior Indebtedness
and nothing in this Indenture shall deprive the Trustee of any of its rights
as such holder. Nothing in this ARTICLE FIFTEEN shall apply to claims of, or
payments to, the Trustee under or pursuant to SECTION 6.07.

SECTION 15.08 ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"TRUSTEE" as used in this ARTICLE FIFTEEN shall in such case (unless the
context shall otherwise require) be construed as extending to and including
such Paying Agent within its meaning as fully for all intents and purposes as
if the Paying Agent were named in this ARTICLE FIFTEEN in addition to or in
place of the Trustee; PROVIDED, HOWEVER, that SECTIONS 15.05 and 15.07 shall
not apply to the Company if its acts as Paying Agent.

SECTION 15.09 SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF THE
COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS.

         No right of any present or future holders of any Senior Indebtedness
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the
Company or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof which any
such holder may


                                      71
<Page>

have or be otherwise charged with. The holders of Senior Indebtedness may, at
any time or from time to time and in their absolute discretion, change the
manner, place or terms of payment, change or extend the time of payment of,
or renew or alter, any such Senior Indebtedness, or amend or supplement any
instrument pursuant to which any such Senior Indebtedness is issued or by
which it may be secured, or release any security therefor, or exercise or
refrain from exercising any other of their rights under the Senior
Indebtedness, including, without limitation, the waiver of default
thereunder, all without notice to or assent from the Holders of the
Securities or the Trustee and without affecting the obligations of the
Company, the Trustee or the Holders of Securities under this ARTICLE FIFTEEN.

SECTION 15.10 HOLDERS OF SENIOR INDEBTEDNESS.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of the Senior Indebtedness, and shall not be liable to any such
holders if it shall mistakenly pay over or distribute money or assets to
Security holders or the Company.

         This instrument may be executed in any number of counterparts, each
of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.
