where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified

or representations by, counsel, unless such Officer knows, or in the exercise of

instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action

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

writing, or the authority of the Person executing the same, may also be proved

<PAGE>

therein mentioned such Person had on deposit with such depository, or exhibited
to it, the Bearer Securities therein described; or such facts may be proved by

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 (i) another such certificate or affidavit bearing a later date
issued in respect of the same Bearer Security is produced, (ii) such Bearer
Security is produced to the Trustee by some other Person, (iii) such Bearer
Security is surrendered in exchange for a Registered Security or (iv) such
Bearer Security is no longer Outstanding. The ownership of Bearer Securities may
also be proved in any other manner which the Trustee deems sufficient; and the
Trustee may in any instance require further proof with respect to any of the
matters referred to in this Section.

            (d) The ownership of Registered Securities shall be proved by the
Register.

            (e) 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.

            (f) If the Company shall solicit from the Holders of any series any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, by or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders of such series entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the Company shall have no obligation to do so, provided that
the Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the
requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date.

            (g) The Trustee may set any day as a record date for the purpose of
determining the Holders of any series entitled to join in the giving or making
of (i) any Notice of Default, (ii) any declaration of acceleration referred to
in Section

                                       12
<PAGE>

5.02, (iii) any direction referred to in Section 5.08 or (iv) any request to
institute proceedings referred to in Section 5.09(2), and (v) any waiver of past
defaults pursuant to Section 5.07, in each case with respect to Securities of
such series. If such a record date is fixed pursuant to this paragraph, the
relevant action may be taken or given before or after such record date, but only
the Holders of record at the close of business on such record date shall be
deemed to be holders of a series for the purpose of determining whether Holders
of the requisite proportion of Outstanding Securities of such series have
authorized or agreed or consented to such action, and for that purpose the
Outstanding Securities of such series shall be computed as of such record date;
provided that no such action by Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date and the proposed action by Holders to be given to the
Company in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 1.06.

            SECTION 1.05. NOTICES, ETC., TO TRUSTEE AND COMPANY. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

            (a) the Trustee by any Holder or by the Company shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) in
writing and mailed, first-class postage prepaid, to the Trustee at 2 N. LaSalle
Street, Suite 1020 Chicago, IL 60602, Attention:______ or

            (b) the Company by the Trustee or by any Holder shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at AmerUs Group Co., 699 Walnut Street, Des Moines, Iowa 50309, Attention:
General Counsel or at any other address previously furnished in writing to the
Trustee by the Company.

            SECTION 1.06. NOTICE TO HOLDERS; WAIVER. Where this Indenture
provides for notice to Holders of an event (i) if any of the Securities affected
by such event are Registered Securities, such notice to the Holders thereof
shall be sufficiently given unless otherwise herein expressly provided) if in
writing and mailed first-class postage prepaid to each such Holder affected by
such event, at his address as it appears in the Register within the time
prescribed for the giving of such notice and, (ii) if any of the Securities
affected by such event are Bearer Securities, notice to the Holders thereof
shall be sufficiently given (unless otherwise herein or in the terms of such
Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New York, and in such other city or cities, if any, as
may be specified as contemplated by Section 3.01.

            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 any case where notice is given to Holders of Bearer
Securities by publication, neither the failure to publish such notice, nor any
defect in any notice so published, shall affect the sufficiency of such notice
with respect to other Holders of Bearer Securities or the sufficiency of any
notice with respect to any Holders of Registered Securities given as provided
herein. Any notice mailed to a Holder in the manner herein prescribed shall be
conclusively deemed to have been received by such Holder, whether or not such
Holder actually receives such notice.

            If by reason of the suspension of regular mail service or by reason
of any other cause it shall be impracticable to give such notice as provided
above, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder with
respect to a Holder of Registered Securities. If it is impossible or, in the
opinion of the Trustee, impracticable to give any notice by publication in the
manner herein required, then such publication in lieu thereof as shall be made
with the approval of the Trustee shall constitute a sufficient publication of
such notice with respect to a Holder of Bearer Securities.

            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.

            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 equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

            SECTION 1.07. 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 1.08. 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 1.09. SEPARABILITY. In case any provision of this Indenture
or the Securities shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

            SECTION 1.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Securities, expressed or implied, shall give to any Person, other than the
parties hereto and their successors hereunder and the Holders, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

            SECTION 1.11. GOVERNING LAW. This Indenture, the Securities and any
coupons appertaining thereto 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. This Indenture is subject to the Trust Indenture Act and if any
provision hereof limits, qualifies or conflicts with any provision of the Trust
Indenture Act, which is required under such Act to be a part of and govern this
Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act which
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. Whether or
not this Indenture is required to be qualified under the Trust Indenture Act,
the provisions of the Trust Indenture Act required to be included in an
indenture in order for such indenture to be so qualified shall be deemed to be
included in this Indenture with the same effect as if such provisions were set
forth herein and any provisions hereof which may not be included in an indenture
which is so qualified shall be deemed to be deleted or modified to the extent
such provisions would be required to be deleted or modified in an indenture so
qualified.

            SECTION 1.12. LEGAL HOLIDAYS. In any case where any Interest Payment
Date, Redemption Date, sinking fund payment date, Stated Maturity or 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 any Security or
coupon other than a provision in the Securities of an series which specifically
states that such provision shall apply in lieu of this Section) payment of
principal, premium, if any, or interest 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 such date;
provided that to the extent such payment is made on such next succeeding
Business Day, no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date, Redemption Date, sinking fund payment
date, Stated Maturity or Maturity, as the case may be.

executing such Securities and coupons, if any, as evidenced by their execution
of the Securities and coupons, if any. If temporary Securities of any series are

as provided in the preceding sentence. If the forms of Securities and coupons,

such series may provide that it shall represent the aggregate or specified
amount of Outstanding Securities of such series from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be reduced or increased
to reflect exchanges. Any endorsement of a Security in global form to reflect
the amount, or any increase or decrease in the amount, or changes in the rights
of Holders, of Outstanding Securities represented thereby, shall be made in such
manner and 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 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. 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 hereof and need not be accompanied
by an Opinion of Counsel.

            The provisions of the last paragraph of Section 3.03 shall apply to
any 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 paragraph of Section 3.03.

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

these officers on the Securities may be manual or facsimile. The coupons, if
any, of Bearer Securities shall bear the facsimile signature of two Officers.

            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.

            At any time and from time to time, the Company may deliver
Securities, together with any coupons appertaining thereto, of any series
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 in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Company or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
delivered to the Trustee prior to the time of the first authentication of
Securities of such series.

            If the form or terms of the Securities of a series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 2.01 and 3.0l, in authenticating such Securities and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 315(a) through
(d) of the Trust Indenture Act) shall be fully protected in relying upon, an
Opinion of Counsel stating,

                  (1) if the forms of such Securities and any coupons have been
established by or pursuant to a Board Resolution as permitted by Section 2.01,
that such forms have been established in conformity with the provisions of this
Indenture;

                  (2) if the terms of such Securities and any coupons have been
established by or pursuant to a Board Resolution as permitted by Section 3.01,
that such terms have been, or in the case of Securities of a series offered in a
Periodic Offering, will be, established in conformity with the provisions of
this Indenture, subject in the case of Securities offered in a Periodic
Offering, to any conditions specified in such Opinion of Counsel; and

                                       22
<PAGE>

                  (3) 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, moratorium and other similar
laws of general applicability relating to or affecting the enforcement of
creditors' rights and to general equity principles and except further as
enforcement thereof may be limited by (A) requirements that a claim with respect
to any Securities denominated other than in Dollars (or a Foreign Currency or
currency unit judgment in respect of such claim) be converted into Dollars at a
rate of exchange prevailing on a date determined pursuant to applicable law or
(B) governmental authority to limit, delay or prohibit the making of payments in
Foreign Currencies or currency units or payments outside the United States.

            Notwithstanding that such form or terms have been so established,
the Trustee shall have the right to decline to authenticate such Securities if,
in the written opinion of counsel to the Trustee (which counsel may be an
employee of the Trustee) reasonably acceptable to the Company, the issue of such
Securities pursuant to this Indenture will adversely affect the Trustee's own
rights, duties or immunities under this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee. Notwithstanding the generality of
the foregoing, the Trustee will not be required to authenticate Securities
denominated in a Foreign Currency if the Trustee reasonably believes that it
would be unable to perform its duties with respect to such Securities.

            Notwithstanding the provisions of Section 3.01 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
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 the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

            With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of
such securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.01 and 3.01 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

            If the Company shall establish pursuant to Section 3.01 that the
Securities of a series are to be issued in whole or in part in global form, then
the Company shall execute and the Trustee shall, in accordance with this Section
and the Company Order with respect to such series, authenticate and deliver one
or more Securities of such series in global form that (i) shall represent and
shall be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be registered, if a Registered

                                       23
<PAGE>

Security, in the name of the Depository for such Security or Securities in
global form or the nominee of such Depository, (iii) shall be delivered by the
Trustee to such Depository or pursuant to such Depository's instruction and (iv)
shall bear the legends set forth in Section 2.04 and the terms of the Board
Resolution or supplemental indenture relating to such series.

            Each Depository designated pursuant to Section 3.01 for a Registered
Security in global form must, at the time of its designation and at all times
while it serves as Depository, be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, and any other applicable statute or
regulation. The Trustee shall have no responsibility to determine if the
Depository is so registered. Each Depository shall enter into an agreement with
the Trustee and the Company governing the respective duties and rights of such
Depository, the Company and the Trustee with regard to Securities issued in
global form.

            Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
as contemplated by Section 3.01.

            No Security or coupon appertaining thereto shall be entitled to any
benefits under this Indenture or be valid or obligatory for any purpose until
the certificate of authentication substantially in the form provided herein is
executed by the manual signature of one of the authorized signatories of the
Trustee or an Authenticating Agent and no coupon shall be valid until the
Security to which it appertains has been so authenticated. Such signature upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered under this Indenture and is
entitled to the benefits of this Indenture. Except as permitted by Section 3.06
or 3.07, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
canceled.

            Notwithstanding the foregoing, if any Security shall have been
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 not 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 of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without coupons, of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities and coupons, if
any. In the case of Securities of any series, such temporary Securities may be
in global form, representing all or a portion of the Outstanding Securities of
such series.

            Except in the case of temporary Securities in global form, each of
which shall be exchanged in accordance with the provisions thereof, if temporary
Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
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 pursuant to Section 9.02 in a Place of Payment for 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 principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor; provided, however, that no definitive Bearer Security, except as may be
provided pursuant to Section 3.01, shall be delivered in exchange for a
temporary Registered Security; and provided further that no definitive Bearer
Security shall be delivered in exchange for a temporary Bearer Security unless
the Trustee shall have received from the person entitled to receive the
definitive Bearer Security a certificate substantially in the form approved in
or pursuant to the Board Resolutions relating thereto and such delivery shall
occur only outside the United States. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series except as otherwise
specified as contemplated by Section 3.01.

            SECTION 3.05. REGISTRATION, TRANSFER AND EXCHANGE. The Company shall
cause to be kept at the Corporate Trust Office of the Trustee or in any office
or agency to be maintained by the Company in accordance with Section 9.02 in a
Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby appointed "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 maintained pursuant to Section
9.02 in a Place of Payment for that series, the Company shall execute and the
Trustee shall authenticate and

                                       25
<PAGE>

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 containing identical terms and
provisions.

            Bearer Securities or any coupons appertaining thereto shall be
transferable by delivery.

            At the option of the Holder, Registered Securities of any series
(except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations and of
a like aggregate principal amount containing identical terms and provisions,
upon surrender of the Registered Securities to be exchanged at such office or
agency. Whenever any Registered Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Registered Securities which the Holder making the exchange is entitled to
receive. Unless otherwise specified as contemplated by Section 3.01, Bearer
Securities may not be issued in exchange for Registered Securities.

            Unless otherwise specified as contemplated by Section 3.01, at the
option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations and of like tenor
and aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any such office or agency, with all unmatured coupons and all
matured coupons in default thereto appertaining. If the Holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or matured
coupon or coupons in default, such exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company and the
Trustee in an amount equal to the face amount of such missing coupon or coupons,
or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there be furnished to them such security or indemnity as they
may require to save each of them and any Paying Agent harmless. If thereafter
the Holder of such Security shall surrender to any Paying Agent any such missing
coupon in respect of which such a payment shall have been made, such Holder
shall be entitled to receive the amount of such payment; provided, however,
that, except as otherwise provided in Section 9.02, 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 any Bearer Security of any
series is surrendered at any such office or agency in exchange for a Registered
Security of the same series after the close of business at such office or agency
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and before the opening of business at such office or agency on the related date
for payment of Defaulted Interest, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date or proposed date of
payment, as the case may be (or, if such coupon is so surrendered with such
Bearer Security, such coupon shall be returned to the person so surrendering

                                       26
<PAGE>

the Bearer Security), 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.

            Each Security issued in global form authenticated under this
Indenture shall be registered in the name of the Depository designated for such
series or a nominee thereof and delivered to such Depository or a nominee
thereof or custodian therefor, and each such Security issued in global form
shall constitute a single Security for all purposes of this Indenture.

            Notwithstanding any other provision of this Section, unless and
until it is exchanged in whole or in part for Securities in certificated form in
the circumstances described below, a Security in global form representing all or
a portion of the Securities of a series may not be transferred except as a whole
by the Depository for such series to a nominee of such Depository or by a
nominee of such Depository to such Depository or another nominee of such
Depository or by such Depository or any such nominee to a successor Depository
for such series or a nominee of such successor Depository.

            If at any time the Depository for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depository
for the Securities of such series or defaults in the performance of its duties
as Depository or if at any time the Depository for the Securities of such series
shall no longer be eligible under Section 3.03, the Company shall appoint a
successor Depository with respect to the Securities of such series. If a
successor Depository for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company selection pursuant to Section 3.01(b)(24)
shall no longer be effective with respect to the Securities of such series and
the Company shall execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of certificated Securities of such series of
like tenor, shall authenticate and deliver Securities of such series of like
tenor in certificated form, in authorized denominations and in an aggregate
principal amount equal to the principal amount of the Security or Securities of
such series of like tenor in global form in exchange for such Security or
Securities in global form.

            The Company may at any time in its sole discretion determine that
Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate principal
amount equal to the principal amount of the Security or Securities of such
series of like tenor in global form in exchange for such Security or Securities
in global form.

            If specified by the Company pursuant to Section 3.01 with respect to
a series of Securities, the Depository for such series may surrender a Security
in global

                                       27
<PAGE>

form of such series in exchange in whole or in part for Securities of such
series in certificated form on such terms as are acceptable to the Company and
such Depository. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge,

         (i)   to each Person specified by such Depository a new certificated
Security or Securities of the same series of like tenor, of any authorized
denomination as requested by such Person in aggregate principal amount equal to
and in exchange for such Person's beneficial interest in the Security in global
form; and

         (ii)  to such Depository a new Security in global form of like tenor in
a denomination equal to the difference, if any, between the principal amount of
the surrendered Security in global form and the aggregate principal amount of
certificated Securities delivered to Holders thereof.

            Upon the exchange of a Security in global form for Securities in
certificated form, such Security in global form shall be canceled by the
Trustee. Unless expressly provided with respect to the Securities of any series
that such Security may be exchanged for Bearer Securities, Securities in
certificated form issued in exchange for a Security in global form pursuant to
this Section shall be registered in such names and in such authorized
denominations as the Depository for such Security in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the Persons
in whose names such Securities are so registered.

            Whenever any Securities are 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.

            All Securities issued upon any registration of transfer or upon any
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 for exchange shall (if so required by the Company, the Registrar
or the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company, the Registrar and the Trustee 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
for any 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 or transfer or exchange of Securities, other
than exchanges pursuant to Section 3.04, 8.06 or 10.07 not involving any
transfer.

            If the Securities of any series (or of any series and specified
tenor) are to be redeemed in part, the Company shall not be required (i) to
issue, register the transfer

                                       28
<PAGE>

of, or exchange any Securities of that series for a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 10.03
and ending at the close of business on the day of such mailing; (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 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.

            The foregoing provisions relating to registration, transfer and
exchange may be modified, supplemented or superseded with respect to any series
of Securities by a Board Resolution or in one or more indentures supplemental
hereto.

            SECTION 3.06. REPLACEMENT SECURITIES. If a mutilated Security or a
Security with a mutilated coupon appertaining to it is surrendered to the
Trustee, together with, in proper cases, such security or indemnity as may be
required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with coupons corresponding to the
coupons appertaining to the surrendered Security, if such surrendered Security
was a Bearer Security, of the same series and date of maturity, if the Trustee's
requirements are met, containing identical terms and of like tenor and of like
principal amount.

            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 replacement Registered Security, if such Holder's Claim appertains to a
Registered Security, or a replacement Bearer Security with coupons corresponding
to the coupons appertaining to the destroyed, lost or stolen Bearer Security or
the Bearer Security to which such lost, destroyed or stolen coupon appertains,
if such Holder's claim appertains to a Bearer Security, of the same series and
principal amount, containing identical terms and provisions and bearing a number
not contemporaneously outstanding with coupons corresponding to the coupons, if
any, appertaining to the destroyed, lost or stolen Security.

            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 or coupon, pay such Security
or coupon; provided, however, that payment of principal of and any premium or
interest on Bearer Securities shall, except as otherwise provided in Section
9.02, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated

                                       29
<PAGE>

by Section 3.01, any interest on Bearer Securities shall be payable only upon
presentation and surrender of the coupons appertaining thereto.

            Upon the issuance of any new Security under this Section, the
Company may require that 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, its agents and
counsel) 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
coupon, if any, or the destroyed, lost or stolen coupon, shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities 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. (a)
Unless otherwise provided as contemplated by Section 3.01 with respect to any
series of Securities, interest, if any, 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.

            Unless otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, (i) interest, if any, on Bearer Securities
shall be paid only against presentation and surrender of the coupons for such
interest installments as are evidenced thereby as they mature and (ii) original
issue discount, if any, on Bearer Securities shall be paid only against
presentation and surrender of such Securities; in either case at the office of a
Paying Agent located outside the United States, unless the Company shall have
otherwise instructed the Trustee in writing, provided that any such instruction
for payment in the United States does not cause any Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations. The interest, if any, on any temporary Bearer Security shall be
paid, as to any installment of interest evidenced by a coupon attached thereto
only upon presentation and surrender of such coupon and, as to other
installments of interest, only upon presentation of such Security for notation
thereon of the payment of such interest. If at the time a payment of principal
of or interest, if any, on a Bearer Security or coupon shall become due, the
payment of the full amount so payable at the office or offices of all the Paying
Agents outside the United States is illegal or effectively precluded because of
the imposition of exchange controls or other similar restrictions on the payment
of such amount in Dollars, then the Company may instruct the Trustee in writing
to make such payments at a Paying Agent located in the United States, provided
that provision for such payment in the

                                       30
<PAGE>

United States would not cause such Bearer Security to be treated as a
"registration-required obligation" under United States laws and regulations.

            (b) Unless otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, any interest on Registered Securities of
any series which is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date for such Registered Securities (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holders on the
relevant Regular Record Date by virtue of their having been such Holders, 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 such Defaulted
Interest to the Persons in whose names such Registered Securities (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this clause (1) 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 such Registered Securities at his
address as it appears in the Register, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been so mailed, such Defaulted
Interest shall be paid to the Persons in whose names such Registered Securities
(or their respective Predecessor Securities) are registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to
the following clause (2). In case a Bearer Security of any series is surrendered
at the office or agency in a Place of Payment for such series in exchange for a
Registered Security of such series after the close of business at such office or
agency on the related proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
proposed date of payment in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

                  (2) The Company may make payment of such Defaulted Interest to
the Persons in whose names such Registered Securities (or their respective
Predecessor Securities) are registered at the close of business on a specified
date in any other lawful manner not inconsistent with the requirements of any
securities exchange on which such Registered Securities may be listed, and upon
such notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed

payment pursuant to this clause (2), such manner of payment shall be deemed
practicable by the Trustee.

                  (c) 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 any
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, premium, if any, and (subject
to Sections 3.05 and 3.07) interest on and Additional Amounts with respect to
such Registered Security and for all other purposes whatsoever, whether or not
such Registered Security be overdue, and neither the Company, the Trustee nor
any agent of the Company or the Trustee shall be affected by notice to the
contrary.

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

            None of the Company, the Trustee or any agent of the Company or the
Trustee shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests. Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Company or the Trustee, or any agent of the Company or the Trustee,
from giving effect to any written certification, proxy or other authorization
furnished by any Depository (or its nominee) as a Holder, with respect to such
Security in global form or impair, as between such Depository and owners of
beneficial interests in such Security in global form, the operation of customary
practices governing the exercise of the rights of such Depository (or its
nominee) as Holder of such Security in global form.

            SECTION 3.09. CANCELLATION. The Company at any time may deliver
Securities and coupons to the Trustee for cancellation. The Registrar and any
Paying Agent shall forward to the Trustee any Securities and coupons surrendered
to them for replacement, for registration of transfer, or for exchange or
payment. The Trustee shall cancel all Securities and coupons surrendered for
replacement, for registration of transfer, or for exchange, payment, redemption
or cancellation. All canceled Securities shall be disposed of by the Trustee and
upon written request therefor, the Trustee shall deliver to the Company a
certificate of disposal. The Company may not issue new Securities to replace
Securities that it has paid or delivered to the Trustee for cancellation.

            SECTION 3.10. COMPUTATION OF INTEREST. Except as otherwise specified
as contemplated by Section 3.01, 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, in such case, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company shall promptly notify the Trustee of any change in the CUSIP
Numbers.

            SECTION 3.12. CURRENCY AND MANNER OF PAYMENT IN RESPECT OF
SECURITIES. (a) Unless otherwise specified with respect to any Securities
pursuant to Section 3.01, with respect to Registered Securities of any series
not permitting the election provided for in paragraph (b) below or the Holders
of which have not made the election provided for in paragraph (b) below, and
with respect to Bearer Securities of any series, except as provided in paragraph
(d) below, payment of the principal of, premium, if any, and interest, if any,
on any Registered or Bearer Security of such series will be made in the currency
or currencies or currency unit or units in which such Registered Security or
Bearer Security, as the case may be, is payable. The provisions of this Section
3.12 may be modified or superseded pursuant to Section 3.01 with respect to any
Securities.

            (b) It may be provided pursuant to Section 3.01, with respect to
Registered Securities of any series, that Holders shall have the option, subject
to paragraphs (d) and (e) below, to receive payments of principal of, premium,
if any, or interest, if any, on such Registered Securities in any of the
currencies or currency units which may be designated for such election by
delivering to the Trustee (or the applicable Paying Agent) a written election
with signature guarantees and in the applicable form established pursuant to
Section 3.01, not later than the close of business on the Election Date
immediately preceding the applicable payment date. If a Holder so elects to
receive such payments in any such currency or currency unit, such election will
remain in effect for such Holder or any transferee of such Holder until changed
by such Holder or such transferee

                                       33
<PAGE>

by written notice to the Trustee (or any applicable Paying Agent) for such
series of Registered Securities (but any such change must be made not later than
the close of business on the Election Date immediately preceding the next
payment date to be effective for the payment to be made on such payment date,
and no such change of election may be made with respect to payments to be made
on any Registered Security of such series with respect to which an Event of
Default has occurred or with respect to which the Company has deposited funds
pursuant to Article IV or with respect to which a notice of redemption has been
given by or on behalf of the Company pursuant to Article X). Any Holder of any
such Registered Security who shall not have delivered any such Election to the
Trustee (or any applicable Paying Agent) not later than the close of business on
the applicable Election Date will be paid the amount due on the applicable
payment date in the relevant currency or currency unit as provided in Section
3.12(a). The Trustee (or the applicable Paying Agent) shall notify the Exchange
Rate Agent as soon as practicable after the Election Date of the aggregate
principal amount of Registered Securities for which Holders have made such
written election.

            (c) If the election referred to in paragraph (b) above has been
provided for with respect to any Registered Securities of a series pursuant to
Section 3.01, then, unless otherwise specified pursuant to Section 3.01 with
respect to any such Registered Securities, not later than the fourth Business
Day after the Election Date for each payment date for such Registered
Securities, the Exchange Rate Agent will deliver to the Company a written notice
specifying, in the currency or currencies or currency unit or units in which
Registered Securities of such series are payable, the respective aggregate
amounts of principal of, premium, if any, and interest, if any, on such
Registered Securities to be paid on such payment date, and specifying the
amounts in such currency or currencies or currency unit or units so payable in
respect of such Registered Securities as to which the Holders of Registered
Securities denominated in any currency or currencies or currency unit or units
shall have elected to be paid in another currency or currency unit as provided
in paragraph (b) above. If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.01, and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 3.01, on the second Business Day
immediately preceding such payment date the Company will deliver to the Trustee
(or the applicable Paying Agent) an Exchange Rate Officers' Certificate in
respect of the Dollar, Foreign Currency or Currencies, ECU or other currency
unit payments to be made on such payment date. Unless otherwise specified
pursuant to Section 3.01, the Dollar, Foreign Currency or Currencies, ECU or
other currency unit amount receivable by Holders of Registered Securities who
have elected payment in a currency or currency unit as provided in paragraph (b)
above shall be determined by the Company on the basis of the applicable Market
Exchange Rate in effect on the second Business Day (the "Valuation Date")
immediately preceding each payment date, and such determination shall be
conclusive and binding for all purposes, absent manifest error.

                                       34
<PAGE>

            (d) If a Conversion Event occurs with respect to a Foreign Currency,
ECU or any other currency unit in which any of the Securities are denominated or
payable otherwise than pursuant to an election provided for pursuant to
paragraph (b) above, then, with respect to each date for the payment of
principal of, premium, if any, and interest, if any, on the applicable
Securities denominated or payable in such Foreign Currency, ECU or such other
currency unit occurring after the last date on which such Foreign Currency, ECU
or such other currency unit was used (the "Conversion Date"), the Dollar shall
be the currency of payment for use on each such payment date (but such Foreign
Currency, ECU or such other currency unit that was previously the currency of
payment shall, at the Company's election, resume being the currency of payment
on the first such payment date preceded by 15 Business Days during which the
circumstances which gave rise to the Dollar becoming such currency no longer
prevail). Unless otherwise specified pursuant to Section 3.01, the Dollar amount
to be paid by the Company to the Trustee or any applicable Paying Agent and by
the Trustee or any applicable Paying Agent to the Holders of such Securities
with respect to such payment date shall be, in the case of a Foreign Currency
other than a currency unit, the Dollar Equivalent of the Foreign Currency or in
the case of a Foreign Currency that is a currency unit, the Dollar Equivalent of
the Currency limit, in each case as determined by the Exchange Rate Agent in the
manner provided in paragraph (f) or (g) below.

            (e) Unless otherwise specified pursuant to Section 3.01, if the
Holder of a Registered Security denominated in any currency or currency unit
shall have elected to be paid in another currency or currency unit or in other
currencies as provided in paragraph (b) above, and (i) a Conversion Event occurs
with respect to any such elected currency or currency unit, such Holder shall
receive payment in the currency or currency unit in which payment would have
been made in the absence of such election and (ii) if a Conversion Event occurs
with respect to the currency or currency unit in which payment would have been
made in the absence of such election, such Holder shall receive payment in
Dollars as provided in paragraph (d) of this Section 3.12 (but, subject to any
contravening valid election pursuant to paragraph (b) above, the elected payment
currency or currency unit, in the case of the circumstances described in clause
(i) above, or the payment currency or currency unit in the absence of such
election, in the case of the circumstances described in clause (ii) above,
shall, at the Company's election, resume being the currency or currency unit of
payment with respect to Holders who have so elected, but only with respect to
payments on payment dates preceded by 15 Business Days during which the
circumstances which gave rise to such currency or currency unit, in the case of
the circumstances described in clause (i) above, or the Dollar, in the case of
the circumstances described in clause (ii) above, as applicable, becoming the
currency or currency unit of payment, no longer prevail).

            (f) The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by the Exchange Rate Agent by converting the specified

                                       35
<PAGE>

Foreign Currency into Dollars at the Market Exchange Rate on the Conversion
Date.

            (g) The "Dollar Equivalent of the Currency Unit" shall be determined
by the Exchange Rate Agent and, subject to the provisions of paragraph (h)
below, shall be the sum of each amount obtained by converting the specified
amount of each Component Currency (as each such term is defined in paragraph (h)
below) into Dollars at the Market Exchange Rate for such Component Currency on
the Valuation Date with respect to each payment.

            (h) For purposes of this Section 3.12 the following terms shall have
the following meanings:

            A "Component Currency" shall mean any currency which, on the
Conversion Date, was a component currency of the relevant currency unit,
including, but not limited to, ECU.

            "Election Date" shall mean the Regular Record Date for the
applicable series of Registered Securities as specified pursuant to Section 3.01
by which the written election referred to in Section 3.12(b) may be made.

            A "Specified Amount" of a Component Currency shall mean the number
of units of such Component Currency or fractions thereof which such Component
Currency represented in the relevant currency unit, including, but not limited
to, ECU, on the Conversion Date. If after the Conversion Date the official unit
of any Component Currency is altered by way of combination or subdivision, the
Specified Amount of such Component Currency shall be divided or multiplied in
the same proportion. If after the Conversion Date two or more Component
Currencies are consolidated into a single currency, the respective Specified
Amounts of such Component Currencies shall be replaced by an amount in such
single currency equal to the sum of the respective specified Amounts of such
consolidated Component Currencies expressed in such single currency, and such
amount shall thereafter be a Specified Amount and such single currency shall
thereafter be a Component Currency. If after the Conversion Date any Component
Currency shall be divided into two or more currencies, the Specified Amount of
such Component Currency shall be replaced by specified amounts of such two or
more currencies, the sum of which, at the Market Exchange Rate of such two or
more currencies on the date of such replacement, shall be equal to the Specified
Amount of such former Component Currency and such amounts shall thereafter be
Specified Amounts and such currencies shall thereafter be Component Currencies.
If, after the Conversion Date of the relevant currency unit, including, but not
limited to, ECU, a Conversion Event (other than any event referred to above in
this definition of "Specified Amount") occurs with respect to any Component
Currency of such currency unit and is continuing on the applicable Valuation
Date, the Specified Amount of such Component Currency shall, for purposes of
calculating the Dollar Equivalent of the Currency Unit, be converted into
Dollars at the Market Exchange Rate in effect on the Conversion Date of such
Component Currency.

                                       36
<PAGE>

            All decisions and determinations of the Exchange Rate Agent
regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit, the Market Exchange Rate and changes in the Specified
Amounts as specified above shall be in its sole discretion and shall, in the
absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company, the Trustee (and any applicable Paying Agent) and all
Holders of Securities denominated or payable in the relevant currency,
currencies or currency units. The Exchange Rate Agent shall promptly give
written notice to the Company and the Trustee of any such decision or
determination.

            In the event that the Company determines in good faith that a
Conversion Event has occurred with respect to a Foreign Currency, the Company
will promptly give written notice thereof to the Trustee of the appropriate
series of Securities (or any applicable Paying Agent) and to the Exchange Rate
Agent (and the Trustee (or such Paying Agent) will promptly thereafter give
notice in the manner provided in Section 1.06 to the affected Holders)
specifying the Conversion Date. In the event the Company so determines that a
Conversion Event has occurred with respect to ECU or any other currency unit in
which Securities are denominated or payable, the Company will promptly give
written notice thereof to the Trustee (or any applicable Paying Agent) and to
the Exchange Rate Agent (and the Trustee (or such Paying Agent) will promptly
thereafter give notice in the manner provided in Section 1.06 to the affected
Holders) specifying the Conversion Date and the Specified Amount of each
Component Currency on the Conversion Date. In the event the Company determines
in good faith that any subsequent change in any Component Currency as set forth
in the definition of Specified Amount above has occurred, the Company will
similarly give written notice to the Trustee (or any applicable Paying Agent)
and to the Exchange Rate Agent.

            The Trustee of the appropriate series of Securities shall be fully
justified and protected in relying and acting upon information received by it
from the Company and the Exchange Rate Agent and shall not otherwise have any
duty or obligation to determine the accuracy or validity of such information
independent of the Company or the Exchange Rate Agent.

            SECTION 3.13. APPOINTMENT AND RESIGNATION OF EXCHANGE RATE AGENT.
(a) Unless otherwise specified pursuant to Section 3.01, if and so long as the
Securities of any series (i) are denominated in a currency other than Dollars or
(ii) may be payable in a currency other than Dollars, or so long as it is
required under any other provision of this Indenture, then the Company will
maintain with respect to each such series of Securities, or as so required, at
least one Exchange Rate Agent. The Company will cause the Exchange Rate Agent to
make the necessary foreign exchange determinations at the time and in the manner
specified pursuant to Section 3.12 for the purpose of determining the applicable
rate of exchange and, if applicable, for the purpose of converting the issued
currency or currencies or currency unit or units into the applicable payment
currency or currency unit for the payment of principal, premium, if any, and
interest, if any, pursuant to Section 3.12.

            (b) No resignation of the Exchange Rate Agent and no appointment of
a successor Exchange Rate Agent pursuant to this Section shall

                                       37
<PAGE>

become effective until the acceptance of appointment by the successor Exchange
Rate Agent as evidenced by a written instrument delivered to the Company and the
Trustee of the appropriate series of Securities accepting such appointment
executed by the successor Exchange Rate Agent.

            (c) If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agency for any cause, with respect to the Securities of one or more series,
the Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 3.01 at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same currency or currencies or currency unit or units).

                                   ARTICLE IV

                     SATISFACTION, DISCHARGE AND DEFEASANCE

            SECTION 4.01. TERMINATION OF COMPANY'S OBLIGATIONS UNDER THE
INDENTURE. This Indenture shall upon a Company Request cease to be of further
effect with respect to Securities of or within any series and any coupons
appertaining thereto (except as to any surviving rights of registration of
transfer or exchange of such Securities and replacement of such Securities which
may have been lost, stolen or mutilated as herein expressly provided for) and
the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to such
Securities and any coupons appertaining thereto when (1) either

            (A) all such Securities previously authenticated and delivered and
all coupons appertaining thereto (other than (i) such coupons appertaining to
Bearer Securities surrendered in exchange for Registered Securities and maturing
after such exchange, surrender of which is not required or has been waived as
provided in Section 3.05, (ii) such Securities and coupons which have been
destroyed, lost or stolen and which have been replaced or paid, as provided in
Section 3.06, (iii) such coupons appertaining to Bearer Securities called for
redemption and maturing after the relevant Redemption Date, surrender of which
has been waived as provided in Section 10.06 and (iv) such 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 9.03) have been delivered
to the Trustee for cancellation; or

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

<PAGE>

(i) have become due and payable, or (ii) will become due and payable at their
Stated Maturity within one year, or (iii) if redeemable at the option of the
Company, 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 irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose an amount in
the currency or currencies or currency unit or units in which the Securities of
such series are payable, sufficient to pay and discharge the entire indebtedness
on such Securities and such coupons not theretofore delivered to the Trustee for
cancellation, for principal, premium, if any, and interest, and any Additional
Amounts payable as specified pursuant to Section 3.01(b)(17) with respect
thereto, 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 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 as to such series have been complied with.

            Notwithstanding the satisfaction and discharge of this Indenture,
the obligation of the Company to the Trustee and any predecessor Trustee under
Section 6.09, 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 subclause (B) of clause (1) of this Section, the obligations of the Trustee
under Section 4.02 and the last paragraph of Section 9.03 shall survive such
satisfaction and discharge.

            SECTION 4.02. APPLICATION OF TRUST FUNDS. Subject to the provisions
of the last paragraph of Section 9.03, 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, premium, if any, and any interest for whose
payment such money has been deposited with or received by the Trustee, but such
money need not be segregated from other funds except to the extent required by
law.

            SECTION 4.03. APPLICABILITY OF DEFEASANCE PROVISIONS; COMPANY'S
OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE. If pursuant to Section 3.01
provision is made for either or both of (i) defeasance of the Securities of or
within a series under Section 4.04 or (ii) covenant defeasance of the Securities
of or within a series under Section 4.05, then the provisions of such Section or
Sections, as the case may be, together with the provisions of Sections 4.06
through 4.09 inclusive, with such modifications thereto as may be specified
pursuant to Section 3.01 with respect to any Securities, shall be applicable to
such Securities and any coupons appertaining thereto,

                                       39
<PAGE>

and the Company may at its option by or pursuant to Board Resolution, at any
time, with respect to such Securities and any coupons appertaining thereto,
elect to have Section 4.04 (if applicable) or Section 4.05 (if applicable) be
applied to such Outstanding Securities and any coupons appertaining thereto upon
compliance with the conditions set forth below in this Article.

            SECTION 4.04. DEFEASANCE AND DISCHARGE. Upon the Company's exercise
of the option specified in Section 4.03 applicable to this Section with respect
to the Securities of or within a series, the Company shall be deemed to have
been discharged from its obligations with respect to such Securities and any
coupons appertaining thereto on and after the date the conditions set forth in
Section 4.06 are satisfied (hereinafter "defeasance"). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Securities and any coupons
appertaining thereto which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 4.07 and the other Sections of this Indenture
referred to in clause (ii) of this Section, and to have satisfied all its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall on a Company
Order execute proper instruments acknowledging the same), except the following
which shall survive until otherwise terminated or discharged hereunder: (i) the
rights of Holders of such Securities and any coupons appertaining thereto to
receive solely from the trust funds described in Section 4.06(a) and as more
fully set forth in such Section, payments in respect of the principal of,
premium, if any, and interest, if any, on such Securities or any coupons
appertaining thereto when such payments are due; (ii) the Company's obligations
with respect to such Securities under Sections 3.04, 3.05, 3.06, 9.02 and 9.03
and with respect to the payment of additional amounts, if any, payable with
respect to such Securities as specified pursuant to Section 3.01(b)(17); (iii)
the rights, powers trusts, duties and immunities of the Trustee hereunder and
(iv) this Article IV. Subject to compliance with this Article IV, the Company
may exercise its option under this Section notwithstanding the prior exercise of
its option under Section 4.05 with respect to such Securities and any coupons
appertaining thereto. Following a defeasance, payment of such Securities may not
be accelerated because of an Event of Default.

            SECTION 4.05. COVENANT DEFEASANCE. Upon the Company's exercise of
the option specified in Section 4.03 applicable to this Section with respect to
any Securities of or within a series, the Company shall be released from its
obligations under Sections 7.01(3), 7.01(4) and 9.07 and, if specified pursuant
to Section 3.01, its obligations under any other covenant, with respect to such
Securities and any coupons appertaining thereto on and after the date the
conditions set forth in Section 4.06 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 7.01(3), 7.01(4)and 9.07 or such other
covenant but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Securities and any coupons appertaining thereto, the Company may omit to
comply with and shall

                                       40
<PAGE>

have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 5.01(3) or
5.01(7), or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby.

            SECTION 4.06. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The
following shall be the conditions to application of Section 4.04 or Section 4.05
to any Securities of or within a series and any coupons appertaining thereto:

            (a) The Company shall have deposited or caused to be deposited
irrevocably with the Trustee (or another trustee satisfying the requirements of
Section 6.12 who shall agree to comply with and shall be entitled to the
benefits of, the provisions of Sections 4.03 through 4.09 inclusive and the last
paragraph of Section 9.03 applicable to the Trustee, for purposes of such
Sections also a "Trustee") as trust funds in trust for the purpose of making the
payments referred to in clauses (x) and (y) of this Section 4.06(a),
specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of such Securities and any coupons appertaining thereto, with
instructions to the Trustee as to the application thereof, (A) money in an
amount (in such currency, currencies or currency unit or units in which such
Securities and any coupons appertaining thereto are then specified as payable at
Maturity), or (B) if Securities of such series are not subject to repayment at
the option of Holders, Government Obligations which through the payment of
interest, principal, premium, if any, and any Additional Amounts in respect
thereof in accordance with their terms will provide not later than one day
before the due date of any payment referred to in clause (x) or (y) of this
Section 4.06(a), money in an amount or (C) a combination thereof in an amount,
sufficient, without reinvestment, in the opinion of a nationally recognized firm
of independent certified public accountants expressed in a written certification
thereof delivered to the Trustee, to pay and discharge, and which shall be
applied by the Trustee to pay and discharge (x) the principal of, premium, if
any, and interest, if any, and any Additional Amounts on such Securities and any
coupons appertaining thereto on the Maturity of such principal or installment of
principal or interest and (y) any mandatory sinking fund payments applicable to
such Securities on the day on which such payments are due and payable in
accordance with the terms of this Indenture and such Securities and any coupons
appertaining thereto. Before such a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date or
dates in accordance with Article X which shall be given effect in applying the
foregoing.

            (b) Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a Default or Event of Default under, this
Indenture or result in a breach or violation of, or constitute a default under,
any

                                       41
<PAGE>

other agreement or instrument to which the Company is a party or by which it is
bound.

            (c) In the case of an election under Section 4.04, the Company shall
have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel
to the effect that (i) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or (ii) since the date of
execution of this Indenture, there has been a change in the applicable Federal
income tax law, in either case to the effect that, and based thereon such
opinion shall confirm that, the Holders of such Securities and any coupons
appertaining thereto will not recognize income, gain or loss for Federal income
tax purposes as a result of such defeasance and will be subject to Federal
income tax on the same amount and in the same manner and at the same times, as
would have been the case if such deposit, defeasance and discharge had not
occurred.

            (d) In the case of an election under Section 4.05, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such covenant defeasance and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such covenant defeasance had not occurred.

            (e) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 4.04 or the covenant defeasance under
Section 4.05 (as the case may be) including those contained in this Section 4.06
other than the 90 day period specified in Section 4.06(g), have been complied
with.

            (f) The Company shall have delivered to the Trustee an Officer's
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

            (g) No event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit or,
with regard to any such event specified in Sections 5.01(5) and (6), at any time
on or prior to the 90th day after the date of such deposit (it being understood
that this condition shall not be deemed satisfied until after such 90th day).

            (h) Such defeasance or covenant defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act of 1940 unless such trust shall be
registered under such Act or exempt from registration thereunder.

                                       42
<PAGE>

            (i) Such defeasance or covenant defeasance shall be effected in
compliance with any additional or substitute terms, conditions or limitations
which may be imposed on the Company in connection therewith as contemplated by
Section 3.01.

            SECTION 4.07. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST. Subject to the provisions of the last paragraph of Section 9.03, all
money and Government Obligations (or other property as may be provided pursuant
to Section 3.01) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.06 in respect of any Securities of any series and any
coupons appertaining thereto shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and any coupons
appertaining thereto 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 such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal, premium, if any, and interest, if any, and any Additional Amounts,
but such money need not be segregated from other funds except to the extent
required by law.

            Unless otherwise specified with respect to any Security pursuant to
Section 3.01, if, after a deposit referred to in Section 4.06(a) has been made,
(i) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 3.12(b) or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 4.06(a) has been made in respect of such
Security, or (ii) a Conversion Event occurs as contemplated in Section 3.12(d)
or 3.12(e) or by the terms of any Security in respect of indebtedness which the
deposit pursuant to Section 4.06(a) has been made, the indebtedness represented
by such Security and any coupons appertaining thereto shall be deemed to have
been, and will be, fully discharged and satisfied through the payment of the
principal of, premium, if any, and interest, if any, on such Security as the
same becomes due out of the proceeds yielded by converting (from time to time as
specified below in the case of any such election) the amount or other property
deposited in respect of such Security into the currency or currency unit in
which such Security becomes payable as a result of such election or Conversion
Event based on the applicable Market Exchange Rate for such currency or currency
unit in effect on the second Business Day prior to each payment date, except,
with respect to a Conversion Event, for such currency or currency unit in effect
(as nearly as feasible) at the time of the Conversion Event.

            SECTION 4.08. REPAYMENT TO COMPANY. Subject to the last paragraph of
Section 9.03, the Trustee (and any Paying Agent) shall promptly pay to the
Company upon Company Request any excess money or securities held by them at any
time.

            SECTION 4.09. INDEMNITY FOR GOVERNMENT OBLIGATIONS. The Company
shall pay, and shall indemnify the Trustee against, any tax, fee or other charge
imposed on or assessed against Government Obligations deposited pursuant to this
Article or the principal and interest and any other amount received on such
Government Obligations.

<PAGE>

            SECTION 4.10. REINSTATEMENT. If the Trustee or the Paying Agent is
unable to apply any money or Government Obligations, as the case may be, in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture, such Securities and any coupons appertaining thereto from which the
Company has been discharged or released pursuant to Section 4.04 or 4.05 shall
be revived and reinstated as though no deposit had occurred pursuant to this
Article with respect to such Securities, until such time as the Trustee or
Paying Agent is permitted to apply all money or Government Obligations, as the
case may be, held in trust pursuant to Section 4.07 with respect to such
Securities and any coupons appertaining thereto in accordance with this Article;
provided, however, that if the Company makes any payment of principal of or any
premium or interest on any such Security following such reinstatement of its
obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities or coupons to receive such payment from the money or
Government Obligations, as the case may be, so held in trust.

                                   ARTICLE V

                              DEFAULTS AND REMEDIES

            SECTION 5.01. EVENTS OF DEFAULT. An "Event of Default" occurs with
respect to the Securities of any series if (whatever the reason for such Event
of Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any payment, decree or order of any court or any
order, rule or regulation of any administrative or governmental body):

                  (1) the Company defaults in the payment of interest on any
Security of that series or any coupon appertaining thereto or any additional
amount payable with respect to any Security of that series as specified pursuant
to Section 3.01(b)(17) when the same becomes due and payable and such default
continues for a period of 30 days;

                  (2) the Company defaults in the payment of the principal of or
any premium on any Security of that series when the same becomes due and payable
at its Maturity or on redemption or otherwise, or in the payment of a mandatory
sinking fund payment when and as due by the terms of the Securities of that
series;

                  (3) the Company fails to comply in any material respect with
any of its agreements or covenants in, or any of the provisions of, this
Indenture with respect to any Security of that series (other than an agreement,
covenant or provision for which non-compliance is elsewhere in this Section
specifically dealt with), and such non-compliance continues for a period of 60
days after there has been given by registered or certified mail, to the Company
by the Trustee or to the Company and the Trustee by the Holders of at least 25%
in principal amount of the Outstanding Securities of the 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;

                                       44
<PAGE>

                  (4) a default under any mortgage, agreement, indenture or
instrument under which there may be issued, or by which there may be secured,
guaranteed or evidenced any Debt of the Company (including this Indenture)
whether such Debt now exists or shall hereafter be created, in an aggregate
principal amount then outstanding of $25,000,000 or more, which default (a)
shall constitute a failure to pay any portion of the principal of such Debt when
due and payable after the expiration of an applicable grace period with respect
thereto or (b) shall result in such Debt becoming or being declared due and
payable prior to the date on which it would otherwise become due and payable,
and such acceleration shall not be rescinded or annulled, or such Debt shall not
be paid in full within a period of 30 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in aggregate principal amount of
the Outstanding Securities of that series a written notice specifying such event
of default and requiring the Company to cause such acceleration to be rescinded
or annulled or to pay in full such Debt and stating that such notice is a
"Notice of Default" hereunder; (it being understood however, that the Trustee
shall not be deemed to have knowledge of such default under such agreement or
instrument unless either (A) a Responsible Officer of the Trustee shall have
actual knowledge of such default or (B) a Responsible Officer of the Trustee
shall have received written notice thereof from the Company, from any Holder,
from the holder of any such indebtedness or from the trustee under any such
agreement or other instrument); provided, however, that if such default under
such agreement or instrument is remedied or cured by the Company or waived by
the holders of such indebtedness, then the Event of Default hereunder by reason
thereof shall be deemed likewise to have been thereupon remedied, cured or
waived without further action upon the part of either the Trustee or any of such
Holders; provided, further, that the foregoing shall not apply to any secured
Debt under which the obligee has recourse (exclusive of recourse for ancillary
matters such as environmental indemnities, misapplication of funds, costs of
enforcement and the like) only to the collateral pledged for repayment so long
as the fair market value of such collateral does not exceed 2% of Total Assets
at the time of the default;

                  (5) the Company, pursuant to or within the meaning of any
Bankruptcy Law, (A) commences a voluntary case or proceeding, (B) consents to
the entry of an order for relief against it in an involuntary case or
proceeding, (C) consents to the appointment of a Custodian of it or for all or
substantially all of its property, (D) makes a general assignment for the
benefit of its creditors, (E) makes an admission in writing of its inability to
pay its debts generally as they become due or (F) takes corporate action in
furtherance of any such action;

                  (6) a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that (A) is for relief against the Company, in
an involuntary case, (B) adjudges the Company as bankrupt or insolvent, or
approves as properly filed a petition seeking reorganization, arrangement, and
adjustment or composition of or in respect of the Company, or appoints a
Custodian of the Company, or for all or substantially all of its property, or
(C) orders the liquidation of the Company and the decree remains unstayed and in
effect for 60 days; or

                                       45
<PAGE>

                  (7) any other Event of Default provided as contemplated by
Section 3.01 with respect to Securities of that series.

            The Company shall deliver to the Trustee, within 90 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any event which is or with the giving of notice or the lapse of time would
become an event which is or with the giving of notice or the lapse of time would
become an Event of Default, its status and what action the Company is taking or
proposes to take with respect thereto.

            As used in the Indenture, the term "Bankruptcy Law" means Title 11,
U.S. Code, or any similar federal or state bankruptcy, insolvency,
reorganization or other law for the relief of debtors. As used in the Indenture,
the term "Custodian" means any receiver, trustee, assignee, liquidator or
similar official under any Bankruptcy Law.

            SECTION 5.02. ACCELERATION; RESCISSION AND ANNULMENT. If an Event of
Default with respect to the Securities of any series at the time Outstanding
occurs and is continuing, the Trustee or the Holders of at least 25% in
aggregate principal amount of all of the Outstanding Securities of that series
by written notice to the Company (and if given by the Holders, to the Trustee),
may declare the principal (or, if the Securities of that series are Original
Issue Discount Securities or Indexed Securities, such portion of the Original
principal amount as may be specified in the terms of that series) of and accrued
interest, if any, on all the Securities of that series to be due and payable and
upon any such declaration such principal (or, in the case of Original Issue
Discount Securities or Indexed Securities, such specified amount) and interest,
if any, shall be 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 aggregate principal amount of the
Outstanding Securities of that series, by written notice to 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) in the currency or currency unit in which that series of
Securities is payable, all overdue interest on all Securities of that series and
any related coupons and any Additional Amounts,

            (B) in the currency or currency unit in which that series of
Securities is payable, 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,

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

                                       46
<PAGE>

            (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 existing Defaults and 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 5.07. 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 or coupon, if any, when such interest or any Additional Amounts 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, if any, the whole amount then due and payable on such
Securities and coupons for principal, premium, if any, and interest and any
Additional Amounts, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal, premium, if any, and on
any overdue interest and any Additional Amounts, at the rate or rates prescribed
therefor in such Securities or coupons, if any, 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 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 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 secure any other proper remedy.

            SECTION 5.04. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file
such proofs of claim and other papers or documents and take such actions
authorized under the Trust Indenture Act as may be necessary or advisable in
order to have the claims of the Trustee and the Holders of Securities allowed in
any judicial proceedings relating to the Company, its creditors or its property.
In particular, 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

                                       47
<PAGE>

authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.09.

            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 of
a Security or coupon 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 of a
Security or coupon in any such proceeding; provided, however, that the Trustee
may, on behalf of the Holders, vote for the election of a trustee in bankruptcy
or similar official and be a member of a creditors' or other similar committee.

            SECTION 5.05. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee, in its own name as an
express trust, without the possession of any of the Securities or coupons or the
production thereof in any proceeding relating thereto and any recovery of
judgment shall, after provision for the reasonable fees and expenses of the
Trustee and its counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect to which judgment was recovered.

            SECTION 5.06. DELAY OR OMISSION NOT WAIVER. No delay or omission by
the Trustee or any Holder of any Securities to exercise any right or remedy
accruing upon an Event of Default shall impair any such right or remedy or
constitute a waiver of or acquiescence in any such Event of Default. 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 5.07. WAIVER OF PAST DEFAULTS. The Holders of a majority in
aggregate principal amount of Outstanding Securities of any series by written
notice to the Trustee may waive on behalf of the Holders of all Securities of
such series and any related coupons a past Default or Event of Default with
respect to that series and its consequences except (i) a Default or Event of
Default in the payment of the principal of, premium, if any, or interest or any
Additional Amounts on any Security of such series or any coupon appertaining
thereto or (ii) in respect of a covenant or provision hereof which pursuant to
Section 8.02 cannot be amended or modified 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.

            SECTION 5.08. CONTROL BY MAJORITY. The Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series affected
(with each such series voting as a class) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising

                                       48
<PAGE>

any trust or power conferred on it with respect to Securities of that series;
provided, however, that (i) the Trustee may refuse to follow any direction that
conflicts with law or this Indenture (ii) the Trustee may refuse to follow any
direction that is unduly prejudicial to the rights of the Holders of Securities
of such series not consenting or of any other series for which the Trustee is
trustee, or that would in the good faith judgment of the Trustee have a
substantial likelihood of involving the Trustee in personal liability and (iii)
the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. Prior to the taking of any action hereunder,
the Trustee shall be entitled to reasonable indemnification satisfactory to the
Trustee against all losses and expenses caused by taking or not taking such
action. This paragraph shall be in lieu of Section 316(a)(1)(A) of the Trust
Indenture Act and such Section 316(a)(1)(A) is hereby expressly excluded from
this Indenture, as permitted By the Trust Indenture Act.

            SECTION 5.09. LIMITATION ON SUITS BY HOLDERS. No Holder of any
Security of any series or any coupons appertaining thereto 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) the Holder has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities of that
series;

                  (2) the Holders of at least 25% in aggregate principal amount
of the Outstanding Securities of that series have made a 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 any loss, liability or expense to
be, or which may be, incurred by the Trustee in pursuing the remedy;

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

                  (5) during such 60 day period, the Holders of a majority in
aggregate principal amount of the Outstanding Securities of that series have not
given to the Trustee a direction inconsistent with such written request.

            No one or more Holders shall have any right in any manner whatever
by virtue of, or by availing of any provision of this Indenture to affect,
disturb or prejudice the rights of any other 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 of such Holders.

            SECTION 5.10. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding
any other provision of this Indenture, the right of any Holder of a Security or
coupon to receive payment of principal of, premium, if any, and, subject to
Sections 3.05 and 3.07, interest on the Security and any Additional Amounts, on
or after

<PAGE>

the respective due dates expressed in the Security (or, in case of redemption,
on the redemption dates), and the right of any Holder of a coupon to receive
payment of interest due as provided in such coupon, or, subject to Section 5.09,
to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

            SECTION 5.11. APPLICATION OF MONEY COLLECTED. If the Trustee
collects any money pursuant to this Article, it shall pay out the money 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, premium, if any, or
interest, and any Additional Amounts upon presentation of the Securities or
coupon or both and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

            FIRST: to the Trustee for amounts due under Section 6.09;

            SECOND: to Holders of Securities and coupons in respect of which or
for the benefit of which such money has been collected for amounts due and
unpaid on such Securities for principal of, premium, if any, and interest or any
Additional Amounts, ratably, without preference or priority of any kind,
according to the amounts due and payable on such Securities for principal,
premium, if any, and interest, respectively; and

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

            The Trustee may fix a record date and payment date for any payment
to Holders pursuant to this Section 5.11. At least 15 days before such record
date, the Trustee shall mail to each Holder and the Company a notice that states
the record date, the payment date and the amount to be paid.

            SECTION 5.12. 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 shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders of Securities and coupons
shall continue as though no such proceeding had been instituted.

            SECTION 5.13. 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 the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any existing right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

            SECTION 5.14. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, 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.

            SECTION 5.15. UNDERTAKING FOR COSTS. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorney's fees and expenses, against any party
litigant in the suit having due regard to the merits and good faith of the
claims or defenses made by the party litigant 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
Company or by the Trustee.

            SECTION 5.16. JUDGMENT CURRENCY. If, for the purpose of obtaining a
judgment in any court with respect to any obligation of the Company hereunder or
under any Security or any related coupon, it shall become necessary to convert
into any other currency or currency unit any amount in the currency or currency
unit due hereunder or under such Security or coupon, then such conversion shall
be made by the Exchange Rate Agent at the Market Exchange Rate as in effect on
the date of entry of the judgment (the "Judgment Date"). If pursuant to any such
judgment, conversion shall be made on a date (the "Substitute Date") other than
the Judgment Date and there shall occur a change between the Market Exchange
Rate as in effect on the Judgment Date and the Market Exchange Rate as in effect
on the Substitute Date, the Company agrees to pay such additional amounts (if
any) as may be necessary to ensure that the amount paid is equal to the amount
in such other currency or currency unit which, when converted at the Market
Exchange Rate as in effect on the Judgment Date, is the amount due hereunder or
under such Security or coupon. Any amount due from the Company, under this
Section 5.16 shall be due as a separate debt and is not to be affected by or
merged into any judgment being obtained for any other sums due hereunder or in
respect of any Security or coupon. In no event, however, shall the Company be
required to pay more in the currency or currency unit due hereunder under such
Security or coupon at the Market Exchange Rate as in effect on the Judgment Date
than the amount of currency or currency unit stated to be due hereunder or under
such Security or coupon so that in any event the Company's obligations hereunder
or under such Security or coupon will be effectively maintained as obligations
in such currency or currency unit, and the Company shall be entitled to withhold
(or be reimbursed for, as the case may be) any excess of the amount actually
realized upon any such conversion on the Substitute Date over the amount due and
payable on the Judgment Date.

                                   THE TRUSTEE

            SECTION 6.01. CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.
(a) The Trustee's duties and responsibilities under this Indenture shall be
governed by the Trust Indenture Act.

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

            SECTION 6.02. RIGHTS OF TRUSTEE. Subject to the provisions of the
Trust Indenture Act:

            (a) The Trustee may conclusively rely and shall be protected in
acting or refraining from acting upon any document believed by it to be genuine
and to have been signed or presented by the proper party or parties; but in the
case of any such documents which by any provisions hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture (but need not confirm or investigate the accuracy of any
mathematical calculations or other facts stated therein).

            (b) Any request or direction of the Company mentioned herein shall
be sufficiently evidenced by a Company Request or Company Order (other than
delivery of any Security, together with any coupons appertaining thereto, to the
Trustee for authentication and delivery pursuant to Section 3.03 which shall be
sufficiently evidenced as provided therein) and any resolution of the Board of
Directors may be sufficiently evidenced by a Board Resolution.

            (c) Before the Trustee acts or refrains from acting, it may consult
with counsel of its selection and/or require an Officers' Certificate. The
Trustee shall not be liable for any action it takes or omits to take in good
faith in reliance on a Board Resolution, the written or oral advice of counsel
reasonably acceptable to the Company and the Trustee (which advice, if oral,
counsel shall promptly confirm in writing to the Trustee), a certificate of an
Officer or Officers delivered pursuant to Section 1.02, an Officers' Certificate
or an Opinion of Counsel.

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

            (e) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers.

                                       52
<PAGE>

            (f) The Trustee shall not be required 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 its rights or powers if it shall
have reasonable grounds for believing that repayment of such funds or indemnity
satisfactory to it against such risk or liability is not reasonably assured to
it.

            (g) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may seem fit, and, if the Trustee shall
determine to make such further inquiry or investigation it shall be entitled to
examine the books, records and premises of the Company, personally or by agent
or attorney at the expense of the Company and shall incur no additional
liability of any kind by reason of such inquiry or investigation.

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

            (i) 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 6.02.

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

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

            (l) The Trustee may request that the Company deliver a certificate
setting forth the names of individuals and/or titles of officers authorized at
such time to take specified actions pursuant to this Indenture.

            SECTION 6.03. TRUSTEE MAY HOLD SECURITIES. The Trustee, any Paying
Agent, any Registrar or any other agent of the Company, in its in individual or
any other capacity, may become the owner or pledgee of Securities and coupons
and,

                                       53
<PAGE>

subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise
deal with the Company, an Affiliate or Subsidiary with the same rights it would
have if it were not Trustee, Paying Agent, Registrar or such other agent.

            SECTION 6.04. MONEY HELD IN TRUST. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed upon in writing with
the Company.

            SECTION 6.05. TRUSTEE'S DISCLAIMER. The recitals contained herein
and in the Securities, except the Trustee's certificate of authentication, shall
be taken as the statements of the Company, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representation as to
the validity or accuracy of this Indenture or the Securities or any coupon. The
Trustee shall not be accountable for the Company's use of the proceeds from the
Securities or for monies paid over to the Company pursuant to the Indenture.

            SECTION 6.06. NOTICE OF DEFAULTS. If a Default occurs and is
continuing with respect to the Securities of any series and if it is known to a
Responsible Officer of the Trustee, the Trustee shall, within 90 days after it
occurs, transmit by mail to the Holders of Securities of such series, in the
manner and to the extent provided in Section 313(c) of the Trust Indenture Act,
notice of all Defaults known to it unless such Default shall have been cured or
waived; provided, however, that except in the case of a Default in payment on
the Securities of any series, the Trustee may withhold the notice if and so long
as the board of directors, the executive committee or a committee of its
Responsible Officers in good faith determines that withholding such notice is in
the interests of Holders of Securities of that series; and provided, further,
that in the case of any Default of the character specified in Section 5.01(3)
with respect to Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof.

            SECTION 6.07. REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after
each May 15 of each year commencing with the first May 15 after the first
issuance of Securities pursuant to this Indenture, the Trustee shall transmit by
mail to all Holders of Securities as provided in Section 313(c) of the Trust
Indenture Act a brief report dated as of such May 15 if required by and in
compliance with Section 313(a) of the Trust Indenture Act. A copy of each such
report shall, at the time of such transmission to Holders, be filed by the
Trustee with each stock exchange, if any, upon which the Securities are listed,
with the Commission and with the Company. The Company will promptly notify the
Trustee when the Securities are listed on any stock exchange. Delivery of such
reports, information and documents to the Trustee is for informational purposes
only and the Trustee's receipt of such shall not constitute constructive notice
of any information relating to financial statements contained therein or
determinable from financial statements contained therein, including the
Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

                                       54
<PAGE>

            SECTION 6.08. SECURITYHOLDER LISTS. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders of Securities of each series. If the
Trustee is not the Registrar, the Company shall furnish to the Trustee
semiannually on or before the last day of June and December in each year, and at
such other times as the Trustee may request in writing, a list, in such form and
as of such date as the Trustee may reasonably require containing all the
information in the possession or control of the Registrar, the Company or any of
its Paying Agents other than the Trustee as to the names and addresses of
Holders of Securities of each such series. If there are Bearer Securities of any
series Outstanding, even if the Trustee is the Registrar, the Company shall
furnish to the Trustee such a list containing such information with respect to
Holders of such Bearer Securities only.

            SECTION 6.09. COMPENSATION AND INDEMNITY. (a) The Company shall pay
to the Trustee from time to time such reasonable compensation for its services
as the Company and the Trustee shall agree in writing from time to time. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred by it in connection
with the performance of its duties under this Indenture, except any such expense
as shall have been caused by its own negligence, bad faith or willful
misconduct. Such expenses shall include the reasonable compensation and expenses
of the Trustee's agents and counsel.

            (b) The Company shall indemnify the Trustee and any Predecessor
Trustee, for and hold it harmless against, any loss or liability, damage, claim
or reasonable expense including taxes (other than taxes based upon or determined
or measured by the income of the Trustee) incurred by it arising out of or in
connection with its acceptance or administration of the trust or trusts
hereunder, including the reasonable costs and expenses of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld.

            (c) The Company need not reimburse any expense or indemnify against
any loss or liability incurred by the Trustee through negligence, bad faith or
willful misconduct.

            (d) To secure the payment obligations of the Company pursuant to
this Section, the Trustee shall have a lien prior to the Securities of any
series on all money or property held or collected by the Trustee, except that
held in trust to pay principal, premium, if any, any interest and any Additional
Amounts, on particular Securities.

                                       55
<PAGE>

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.01(5) or Section 5.01(6), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

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

            SECTION 6.10. REPLACEMENT OF TRUSTEE. (a) The resignation or removal
of the Trustee and the appointment of a successor Trustee shall become effective
only upon the successor Trustee's acceptance of appointment as provided in
Section 6.11.

            (b) The Trustee may resign at any time with respect to the
Securities of any series by giving written notice thereof to the Company.

            (c) The Holders of a majority in aggregate principal amount of the
Outstanding Securities of any series may remove the Trustee with respect to that
series by so notifying the Trustee and the Company and may appoint a successor
Trustee for such series with the Company's consent.

            (d) If at any time:

                  (1) the Trustee fails to comply with Section 310(b) of the
Trust Indenture Act after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Security for any least six months,
or

                  (2) the Trustee shall cease to be eligible under Section 6.12
of this Indenture or Section 310(a) of the Trust Indenture Act and shall fail to
resign 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

                  (3) the Trustee becomes incapable of acting, is adjudged a
bankrupt or an insolvent or a receiver or public officer takes charge of the
Trustee or its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (i) the Company by or
pursuant to a Board Resolution may remove the Trustee with respect to all
Securities, or (ii) subject to Section 315(e) of the Trust Indenture Act, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

            (e) 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 or removal, the Trustee resigning
or being removed may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

                                       56
<PAGE>

            (f) If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, with respect to Securities of one or more
series, the Company, by or pursuant to Board Resolution, shall promptly appoint
a successor Trustee with respect to the Securities to 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 of such 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 and accepted appointment in the manner required by Section 6.11, any
Holder 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.

            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 shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee, without further act, deed or conveyance,
shall become vested with all the rights, powers and duties of the retiring
Trustee; but, on the request of the Company or the successor Trustee, such
retiring 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.

            (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 such successor Trustee shall execute and deliver an
indenture supplemental hereto wherein such successor Trustee shall accept such
appointment and which (i) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, such 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, (ii) 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
or the retiring Trustee with respect to the Securities of that or those series
as to which the retiring Trustee is

                                       57
<PAGE>

not retiring shall continue to be vested in the retiring Trustee, and (iii)
shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
another such Trustee and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
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 such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to the 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 the Trust Indenture Act.

            (e) 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 for notices to the Holders of Securities 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 6.12. ELIGIBILITY; DISQUALIFICATION. There shall at all
times be a Trustee hereunder which shall be eligible to act as Trustee under
Section 310(a)(1) of the Trust Indenture Act and shall have a combined capital
and surplus of at least $100,000,000. If such Trustee publishes reports of
condition at least annually, pursuant to law or the requirements of Federal,
State, Territorial or District of Columbia supervising or examining authority,
then, for the purposes of this Section, the combined capital and surplus of such
Trustee 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 heretofore specified
in this Article.

            SECTION 6.13. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS. Any corporation into which the Trustee may be merged or converted or
with

                                       58
<PAGE>

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 to the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. 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 6.14. APPOINTMENT OF AUTHENTICATING AGENT. The Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue, exchange,
registration of transfer or partial redemption thereof, 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. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which Instrument shall
be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and, except as may otherwise be provided pursuant to
Section 3.01, shall at all times be a bank or trust company or corporation
organized and doing business and in good standing under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $50,000,000 and subject to supervision or examination by
Federal or State authorities. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid 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. In case at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

                                       59
<PAGE>

            An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 1.06. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

            The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
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 endorsed
thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication substantially in the
following form:

            This is one of the Securities of the series described in the
within-mentioned Indenture.

                  (1) the Person formed by or surviving any such consolidation
or any merger (if other than the Company), or to which such transfer or lease
shall have been made, is a corporation organized and existing under the laws of
the United States, any State thereof or the District of Columbia;

                  (2) the Person formed by or surviving any such consolidation
or merger (if other than the Company), or to which such transfer or lease shall
have been made, expressly assumes by supplemental indenture hereto executed and
delivered to the Trustee, inform satisfactory to the Trustee, the due and
punctual payment of the principal, premium, if any, interest, if any and any
Additional Amounts, with respect to all of the Securities and the performance or
observance of every covenant under this Indenture and the Securities on the part
of the Company to be performed under the Securities, the coupons and this
Indenture;

                  (3) immediately after giving effect to the transaction and

incurred by the Company or such Subsidiary at the time of such transaction no
Default or Event of Default exists and is continuing; and

                  (4) if, as a result of any such consolidation or merger or
such conveyance, transfer or lease, properties or assets of the Company would
become subject to a mortgage, pledge, lien, security interest or other
encumbrance which would not be permitted by the Securities of any series, the
Company or such successor Person, as the case may be, shall take such steps as
shall be necessary effectively to secure such Securities equally and ratably
with all indebtedness secured thereby.

            The Company shall deliver to the Trustee prior to the proposed
transaction an Officers' Certificate to the foregoing effect and an Opinion of
Counsel stating that the proposed transaction and such supplemental indenture
comply with this Indenture and that all conditions precedent to the consummation

            In the event of the assumption by a successor corporation as
provided in clause (2) above, such successor corporation shall succeed to and be
substituted for the Company hereunder and under the Securities with the same
effect as if it had been named hereunder and thereunder and, except in the case
of a lease, any coupons appertaining thereto and all such obligations of the
Company shall terminate.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

            SECTION 8.01. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.
Without the consent of any Holders, the Company, when authorized by a Board
Resolution, and the Trustee at any time and from time to time, may enter into

obligations of the Company herein and in the Securities; or

                  (2) to add to the covenants of the Company for the benefit of
the Holders of all or any series of Securities (and if such covenants are to be
for the benefit less than all series of Securities, stating that such covenants
are expressly being included solely for the benefit of such series) or to
surrender any right or power herein conferred upon the Company; or

                  (3) to add any additional Events of Default with respect to
all or any series of Securities (and if such Events of Default are to be for the

Default are expressly included solely for the benefit of such series); or

                  (4) to add to or change any of the provisions of this
Indenture to such extent as shall be necessary to facilitate the issuance of
Bearer Securities (including, without limitation to provide that Bearer
Securities may be registrable as to principal only) or to facilitate the
issuance of Securities in global form; or

                  (5) to change or eliminate any of the provisions of this
Indenture, provided that any such change or elimination shall become effective
only when there is no Security Outstanding of any series created prior to the
execution of such supplemental indenture which is entitled to the benefit of
such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
as permitted by Sections 2.01 and 3.01; or

                  (8) to evidence and provide for the acceptance of appointment

subject to its jurisdiction of principal, premium, if any, or interest, if any,
on Bearer Securities or coupons, if any; or

                  (10) to correct or supplement any provision herein which may
be inconsistent with any other provision herein or to make any other provisions
with

                                       62
<PAGE>

respect to matters or questions arising under this Indenture, provided such
action shall not adversely affect the interests of the Holders of Securities of
any series; or

                  (11) to cure an ambiguity or correct any mistake, provided
such action shall not adversely affect the interests of the Holders of
Securities of any series.

            SECTION 8.02. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS. With
the written consent of the Holders of a majority of the aggregate principal
amount of the Outstanding Securities of each series adversely affected by such
supplemental indenture (with the Securities of each series voting as a class),
the Company, when authorized by a Board Resolution, and the Trustee may enter
into an indenture or indentures supplemental hereto to add any provisions to or
to change or eliminate any provisions of this Indenture or of any other
indenture supplemental hereto or to modify the rights of the Holders of such
Securities; provided, however, that without the consent of the Holder of each
Outstanding Security affected thereby, a supplemental indenture under this
Section may not:

                  (1) change the Stated Maturity of the principal of, or
premium, if any, on, or any installment of principal of or premium, if any, or
interest on, or any Additional Amounts on, any Security, or reduce the principal
amount thereof or the rate of interest thereon or any premium payable upon the

Amounts thereon is determined or reduce the amount of the principal of any
Original Issue Discount Security or Indexed Security that would be due and
payable upon a declaration of acceleration of the Maturity thereof pursuant to
Section 5.02, or change the Place of Payment where or the currency in which any
Securities or any premium or the interest or Additional Amounts thereon is
payable, or impair the right to institute suit for the enforcement of any such
payment on or after the Stated Maturity thereof (or, in the case of redemption,
on or after the Redemption Date);

                  (2) reduce the percentage in principal amount of the
Outstanding Securities affected thereby, the consent of whose Holders is

Indenture;

                  (3) change any obligation of the Company to maintain an office

increase any percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived with the consent of the Holders of each
Outstanding Security affected thereby.

            A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit

                                       63
<PAGE>

of one or more particular series of Securities, or which modifies the rights of
the Holders of Securities of such series with respect to such covenant or other
provision shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series.

            It is not necessary under this Section 8.02 for the Holders to
consent to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

            SECTION 8.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment
to this Indenture or the Securities of one or more series shall be set forth in
a supplemental indenture that complies with the Trust Indenture Act as then in
effect.

            SECTION 8.04. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

            SECTION 8.05. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution
of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby.

            SECTION 8.06. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.
Securities, including any coupons, of any series authenticated and delivered
after the execution of any supplemental indenture pursuant to this Article may,
and shall if required by the Trustee, bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities including any coupons of any series
so modified as to conform, in the opinion of the Trustee and the Company, to any
such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities including any coupons of such series.

                                   ARTICLE IX

                                    COVENANTS

            SECTION 9.01. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST.
The Company covenants and agrees for the benefit of the Holders of each series
of Securities that it will duly and punctually pay the principal of, premium, if
any, and interest together with Additional Amounts, if any, on the Securities of
that series in accordance with the terms of the Securities of such series, any
coupons appertaining thereto and this Indenture. An installment of principal,
premium, if any, or interest, if any, of any Additional Amounts shall be
considered paid on the date it is due if the Trustee or Paying Agent holds on
that date money designated for and sufficient to pay the installment.

            SECTION 9.02. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a
series are issued as Registered Securities, the Company will maintain in each
Place of Payment for any series of Securities 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, (i) subject
to any laws or regulations applicable thereto, an office or agency in a Place of
Payment for that series which is located outside the United States where
Securities of that series and related coupons may be presented and surrendered
for payment; 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 (ii) subject to any laws or regulations applicable thereto, an
office or agency in a Place by Payment for that series which is located outside
the United States, 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 maybe served. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of any such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

            Unless otherwise specified as contemplated by Section 3.01, 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, by check mailed to any
address in United States, by transfer to an account located in the United States
or upon presentation or surrender in the United States of a Bearer Security or
coupon for payment, even if the

                                       65
<PAGE>

payment would be credited to an account located outside 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 or interest on any
such Bearer Security shall be made at the office of the Company's Paying Agent
located within the United States, if (but only if) payment in Dollars of the
full amount of such principal, premium or interest, 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 the Securities (including any coupons, if any) 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 an agency in each Place of Payment for
Securities (including any coupons, if any) of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency. Unless otherwise specified as contemplated by Section 3.01, the Trustee
shall initially serve as Paying Agent.

            If and so long as the Securities of any series (i) are denominated
in a currency other than Dollars or (ii) may be payable in currency other than
Dollars, or so long as it is required under any other provision of this
Indenture, then the Company will maintain with respect to each such series of
Securities or as so required, an Exchange Rate Agent.

            SECTION 9.03. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST;
UNCLAIMED MONEY. If the Company shall at any time act as its own Paying Agent
with respect to any series of Securities, it will, on or before each due date of
the principal of, premium, if any, or interest or any Additional Amount, 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, premium, if
any, or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
in writing of its action or failure so to act.

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

                  (1) hold all sums held by it for the payment of the principal
of, premium, if any, or interest or Additional Amounts on Securities of that
series in trust for the benefit of the Persons entitled thereto until such sums
shall be paid to such Persons or otherwise disposed of as herein provided;

                                       66
<PAGE>

                  (2) give the Trustee notice of any default by the Company (or
any other obligor upon the Securities of that series) in the making to any
payment of principal, premium, if any, or interest or Additional Amounts on the
Securities; and

                  (3) at any time during the continuance of any such default,
upon the written request of the Trustee, forthwith pay to the Trustee all sums
so held in trust by such Paying Agent.

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge or defeasance 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 terms 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 any principal, premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium, if any, or interest or Additional Amount has
become due and payable shall be paid to the Company on Company Request or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security and coupon, if any, shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, 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, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in The City of New York, or cause to be
mailed to such Holder, 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 9.04. CORPORATE EXISTENCE. Subject to Article VII, the
Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.04 shall prevent
the abandonment or termination of any right or franchise of the Company if, in
the opinion of the Company, such abandonment or termination is in the best
interests of the Company and not prejudicial in any material respect to the
Holders of the Securities.

            SECTION 9.05. REPORTS BY THE COMPANY. The Company covenants:

            (a) to file with the Trustee, within 30 days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and
regulations

                                       67
<PAGE>

prescribe) which the Company may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934,
as amended; or, if the Company is not required to file information, documents or

the Commission, in accordance with rules and regulations prescribed from time to
time by the Commission, such of the supplementary and periodic information,
documents and reports which may be required pursuant to Section 13 of the
Securities Exchange Act of 1934, as amended, in respect of a security listed and

time in such rules and regulations;

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

            (c) to transmit to all Holders of Securities, within 30 days after
the filing thereof with the Trustee, in the manner and to the extent provided in
Section 313(c) of the Trust Indenture Act, such summaries of any information,
documents and reports required to be filed by the Company pursuant to
subsections (a) and (b) of this Section 9.05, as may be required by rules and
regulations prescribed from time to time by the Commission.

Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including information
concerning the Company's compliance with any of its covenants hereunder,
provided that the foregoing shall not relieve the Trustee of any of its
responsibilities hereunder.

            SECTION 9.06. ANNUAL REVIEW CERTIFICATE; NOTICE OF DEFAULTS OR
EVENTS OF DEFAULT. The Company covenants and agrees to deliver to the Trustee,
within 120 days after the end of each fiscal year of the Company ending after
the date hereof, a certificate from the principal executive officer, principal
financial officer or principal accounting officer of the Company, covering the
preceding calendar year, stating whether or not to the best knowledge of the
signer(s) thereof the Company is in default in the performance, observance or
fulfillment of or compliance with any of the terms, provisions, covenants and
conditions of this Indenture, and if the Company shall be in default, specifying
all such defaults and the nature and status thereof of which they may have
knowledge. For the purposes of this Section 9.06, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

            SECTION 9.07. BOOKS OF RECORD AND ACCOUNT. The Company will keep
proper books of record and account, either on a consolidated or individual
basis. The Company shall cause its books of record and account to be examined
either on a

                                       68
<PAGE>

consolidated or individual basis, by one or more firms of independent public
accountants not less frequently than annually. The Company shall prepare its
financial statements in accordance with GAAP.

            SECTION 9.08. STATEMENT BY OFFICERS AS TO DEFAULT. The Company shall
deliver to the Trustee, as soon as possible and in any event within five days
after the Company becomes aware of the occurrence of any Event of Default or an
event which, with notice or the lapse of time or both, would constitute an Event
of Default, an Officers' Certificate setting forth the details of such Event of
Default or default and the action which the Company proposes to take with
respect thereto.

                                   ARTICLE X

                                   REDEMPTION

            SECTION 10.01. APPLICABILITY OF ARTICLE. Securities (including
coupons, if any) of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 3.01 for Securities of any series) in
accordance with this Article.

            SECTION 10.02. ELECTION TO REDEEM NOTICE TO TRUSTEE. The election of
the Company to redeem any Securities, including coupons, if any, shall be
evidenced by or pursuant to a Board Resolution. In case of any redemption at the
election of the Company of less than all the Securities or coupons, if any, of
any series, the Company shall, at least 60 days prior to the Redemption Date
fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and Redemption Price, of
the principal amount of Securities of such series to be redeemed and, if
applicable, of the tenor of the Securities 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 10.03. SELECTION OF SECURITIES TO BE REDEEMED. Unless
otherwise specified as contemplated by Section 3.01, if less than all the
Securities (including coupons, if any) of a series with the same terms are to be
redeemed, the Trustee, not more than 45 days prior to the redemption date, shall
select the Securities of the series to be redeemed in such manner as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. The Trustee shall make the selection
from Securities of the series that are Outstanding and that have not previously
been called for redemption and may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities, including
coupons, if any, of that series or any integral multiple thereof) of the
principal amount of

                                       69
<PAGE>

Securities, including coupons, if any, of such series of a denomination larger
than the minimum authorized denomination for Securities of that series. The
Trustee shall promptly notify the Company in writing of the Securities selected
by the Trustee for redemption and, in the case of any Securities selected for
partial redemption, the principal amount thereof to be redeemed. If the Company
shall so direct, Securities registered in the name of the Company, any Affiliate
or any Subsidiary thereof shall not be included in the Securities selected for
redemption. If less than all the Securities of any series with differing issue
dates, interest rates and stated maturities are to be redeemed, the Company in
its sole discretion shall select the particular Securities to be redeemed and
shall notify the Trustee in writing thereof at least 45 days prior to the
relevant redemption date.

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

            SECTION 10.04. NOTICE OF REDEMPTION. Unless otherwise specified as
contemplated by Section 3.01, notice of redemption shall be given in the manner
provided in Section 1.06 not less than 30 days nor more than 60 days prior to
the Redemption Date to the Holders of the Securities to be redeemed. Depositor
shall give 5 days advance written notice or such shorter time as may be
agreeable to the Trustee. All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

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

                  (4) in case any Security is to be redeemed in part only, the
notice which relates to such Security shall state that on and after the
Redemption Date, upon surrender of such Security, the Holder will receive,
without a charge, a new Security or Securities of authorized denominations for
the principal amount thereof remaining unredeemed;

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

                  (6) that Securities of the series called for redemption and
all unmatured coupons, if any, appertaining thereto must be surrendered to the
Paying Agent to collect the Redemption Price;

<PAGE>

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

                  (8) that the redemption is for a sinking fund, if such is the
case;

                  (9) that unless otherwise specified in such notice, Bearer
Securities of any series, if any, surrendered for redemption must be accompanied
by all coupons maturing subsequent to the Redemption Date or the amount of any
such missing coupon or coupons will be deducted from the Redemption Price,
unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished; and

                  (10) the CUSIP number, if any, of the Securities.

            Notice of redemption of Securities to be redeemed 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 10.05. DEPOSIT OF REDEMPTION PRICE. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article XI, segregate and hold in
trust as provided in Section 9.03) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.01 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

            Unless any Security by its terms prohibits any sinking fund payment
obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

            SECTION 10.06. 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 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 any such interest
appertaining to any Bearer Security so to be redeemed, except to the extent
provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including coupons, if any, for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest (and any
Additional Amounts) to the Redemption Date; provided, however, that installments
of interest on Bearer

                                       71
<PAGE>

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 and its
possessions (except as otherwise provided in Section 9.02) and, unless otherwise
specified as contemplated by Section 3.01, only upon presentation and surrender
to 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
Bearer Security may be paid after deducting from the Redemption Price an amount
equal to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest (and any Additional Amounts) represented by
coupons shall be payable only at an office or agency located outside of the
United States (except as otherwise specified pursuant to Section 9.02) and,
unless otherwise provided 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 premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

            SECTION 10.07. SECURITIES REDEEMED IN PART. Upon surrender of a
Registered Security that is redeemed in part at any Place of Payment therefor
(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), the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of that Security, without service charge a new Registered
Security or Securities of the same series, having the same form, terms and
Stated Maturity, in any authorized denomination equal in aggregate principal
amount to the unredeemed portion of the principal amount of the Security
surrendered.

                                   ARTICLE XI

                                  SINKING FUNDS

            SECTION 11.01. 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.

                                       72
<PAGE>

            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 11.02. 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 11.02. SATISFACTION OF SINKING FUND PAYMENTS WITH
SECURITIES. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured coupons appertaining
thereto and (ii) 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 11.03. 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 an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied be delivering and crediting Securities of that series pursuant to
Section 11.02 and will also deliver to the Trustee any Securities to be so
delivered to the extent it has not previously done so. Not less than 30 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 10.03 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 10.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
10.06 and 10.07.

            This Indenture may be executed in any number of counterparts, each
of which shall be an original, but such counterparts shall together constitute
but one instrument.

            IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, all as of the day and year first above written.
