consent or waiver, only Securities which the Trustee actually knows to be so
owned shall

                  (a) a statement that each individual signing such certificate

            SECTION 1.03 FORMS OF DOCUMENTS DELIVERED TO TRUSTEE. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

            Any certificate or opinion of an Officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such Officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an Officer or Officers of the Company stating that the

<PAGE>

            Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

            SECTION 1.04 ACTS OF HOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders
in person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such Agent shall be
sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section.

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

                  (c) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed by any trust
company, bank, banker or other depository, wherever situated if such certificate
shall be deemed by the Trustee to be satisfactory, showing that at the date
therein mentioned such Person had on deposit with such depository, or exhibited
to it, the Bearer Securities therein described; or such facts may be proved by
the certificate or affidavit of the Person holding such Bearer Securities, if
such certificate or affidavit is deemed by the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (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

                                       11
<PAGE>

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 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

                                       12
<PAGE>

(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,

2 N.LaSalle Street, Suite 1020, Chicago, IL 60602, or

                  (b) the Company by the Trustee or by any Holder shall be

            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 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

                                       13
<PAGE>

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

                                       14
<PAGE>

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 a 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.

as provided in the preceding sentence. If the forms of Securities and coupons,
if any, of any series are established by, or by action taken pursuant to, a
Board Resolution, a copy of the Board Resolution together with an appropriate
record of any such action taken pursuant thereto, including a copy of the
approved form of Securities or coupons, if any, shall be certified by the

series are issuable in whole or in part in global form, any such Security of
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

limitation, the receipt by the Trustee of oral or electronic instructions from
the Company or its duly authorized agents, promptly confirmed in writing)

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

                        (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.

                                       22

            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 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 deliver, in the name of the designated transferee
or transferees, one or more new Registered Securities of the same

                                       24
<PAGE>

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 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,

                                       25
<PAGE>

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 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,

                                       26
<PAGE>

                        (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 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

                                       27
<PAGE>

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 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.

                                       28
<PAGE>

            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 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:

                                       29
<PAGE>

                        (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
      Company shall deposit with the Trustee an amount of money equal to the
      aggregate amount proposed to be paid in respect of such Defaulted Interest
      or shall make arrangements satisfactory to the Trustee for such deposit
      prior to the date of the proposed payment, such money when deposited to be
      held in trust for the benefit of the 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

                                       31
<PAGE>

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 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

                                       32
<PAGE>

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.

                  (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

                                       33
<PAGE>

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 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

                                       34
<PAGE>
      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.

            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

                                       35
<PAGE>

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
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 (including but not
limited to Article XII) 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

                                  36

            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 (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

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

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, 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

                                       38
<PAGE>

within a series, the Company shall be released from its obligations under
Sections 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(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 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

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

                  (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 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.

                  (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.

<PAGE>

                  (j) No event or condition shall exist that, pursuant to
Article XII, would prevent the Company from making payments of principal of,
premium, if any, interest, if any and any Additional Amounts on the Securities.

            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.

            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

                                       41
<PAGE>

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 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;

                  (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

                                    42
<PAGE>

      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 a 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

                                    43
<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 judgement 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

                                  44
<PAGE>

            rates prescribed therefor in such Securities and any Additional
            Amounts payable, and

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

and

                  (2) all 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

                                       45
<PAGE>

or other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.09.

            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 any trust or power conferred on

                                       46
<PAGE>

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

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

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

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

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.

            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.

                  (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 adequate
indemnity against such risk or liability is not reasonably assured to it.

                                       50
<PAGE>

                  (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, 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

                                       51
<PAGE>

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.

            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

                                       52
<PAGE>

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 or bad
faith.

                  (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.

            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

                                    53
<PAGE>

      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.

                  (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 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

                                       55
<PAGE>

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 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

                                       56
<PAGE>

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.

            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.

                  CONSOLIDATION, MERGER OR SALE BY THE COMPANY

            SECTION 7.01 CONSOLIDATION, MERGER OR SALE OF ASSETS PERMITTED. The
Company shall not consolidate with or merge with or into, or transfer or lease
all or substantially all of its assets to, any Person unless:

                  (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, in form 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
      treating any indebtedness which becomes an obligation of the Company or a
      Subsidiary of the Company as a result of such transaction as having been
      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
of the transaction under this Indenture have been met.

            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 any coupons
appertaining thereto and, except in the case of a lease, all such obligations of
the Company shall terminate.

                             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
indentures supplemental hereto, in form reasonably satisfactory to the Trustee,
for any of the following purposes:

                  (1) to evidence the succession of another corporation to the
      Company and the assumption by any such successor of the covenants and
      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 benefit of less than all series of Securities, stating that such
      Events of 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
      hereunder by a successor Trustee with respect to the Securities of one or
      more series and to add to or change any of the provisions of this
      Indenture as shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee, pursuant
      to the requirements of Section 6.11; or

                                       60
<PAGE>

                  (9) if allowed without penalty under applicable laws and
      regulations, to permit payment in the United states (including any of the
      States and District of Columbia), its territories, its possessions and
      other areas 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 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 redemption, repurchase or repayment thereof, or
      change the manner in which the amount of any principal thereof or premium,
      if any, or interest or Additional 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
      required for any such supplemental indenture, or the consent of whose
      Holders is required for any waiver (of compliance with certain provisions
      of this Indenture or certain defaults hereunder and their consequences)
      provided for in this Indenture;

                                       61
<PAGE>

                  (3) change any obligation of the Company to maintain an office
      or agency in the places and for the purposes specified in Section 9.02; or

                  (4) make any change in Section 5.07 or this 8.02 except to
      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 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

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.

                                       62

            SECTION 8.07 EFFECT ON SENIOR INDEBTEDNESS. No supplemental
indenture shall adversely affect the rights of any holder of Senior Indebtedness

                                   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.

            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 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

                                       63
<PAGE>

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;

                  (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.

                                       64
<PAGE>

            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 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 reports pursuant to either of such Sections, then to file with the
Trustee and 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 registered on a national securities exchange as may be prescribed

                                   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 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.

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;

                        (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.

                                       68
<PAGE>

            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 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

                                       69
<PAGE>

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.

            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

                                       70
<PAGE>

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.

                                  ARTICLE XII
                           SUBORDINATION OF SECURITIES

            SECTION 12.01 AGREEMENT TO SUBORDINATE. The Company, for itself, its
successors and assigns, covenants and agrees, and each Holder of Securities, by
his acceptance thereof, likewise covenants and agrees, that the payment of the
principal of (and premium, if any), interest on and any Additional Amounts
payable in respect of each and all of the Securities is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth in this
Article XII (subject to the provisions of Article IV), in right of payment to
the prior payment in full of all Senior Indebtedness.

            SECTION 12.02 DISTRIBUTION ON DISSOLUTION, LIQUIDATION AND
REORGANIZATION. In the event of (i) any insolvency, bankruptcy, receivership,
liquidation, reorganization, readjustment, composition or other similar
proceeding relating to the Company or its property, (ii) any proceeding for the
liquidation, dissolution or other winding-up of the Company, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings,
(iii) any assignment by the Company for the benefit of creditors or (iv) any
other marshaling of the assets and liabilities of the Company then, and in any
such event specified in (i), (ii), (iii) or (iv) (each such event, if any,
herein sometimes referred to as a "Proceeding") (subject to the power of a court
of competent jurisdiction to make other equitable provision reflecting the
rights conferred in this Indenture upon the Senior Indebtedness and the holders
thereof with respect to the Securities and the Holders thereof by a lawful plan
or reorganization under applicable Bankruptcy Law),

                  (a) the holders of all Senior Indebtedness shall first be
entitled to receive payment in full of the principal thereof, premium, if any,
any interest or any additional amounts required in respect of certain taxes, and
any interest thereon, due thereon or provision must first be made for such
payment in cash or cash equivalents or any other manner acceptable to the
holders of such Senior Indebtedness before any payment or distribution, whether
in cash, securities or property (including any payment or distribution which may
be payable or

                                       71
<PAGE>

deliverable by reason of the payment of any other indebtedness of the Company
subordinated to the payment of the Securities, such payment or distribution
being referred to as a "Junior Subordinated Payment", but excluding any payment
or distribution of securities of the Company provided for by a plan of
reorganization or readjustment authorized by an order or decree of a court of
competent jurisdiction in a reorganization proceeding under any applicable
Bankruptcy Law or of any other corporation provided for by such plan of
reorganization or readjustment which securities are subordinated in right of
payment to all then outstanding Senior Indebtedness to substantially the same
extent as the Securities are so subordinated as provided in this Article), shall
be made by the Company on account of principal, premium, interest or Additional
Amounts of or on the Securities or interest on overdue amounts thereof; and

                  (b) any payment or distribution of assets of the Company of
any kind or character, whether in cash, property or securities, including any
Junior Subordinated Payment, to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article (and
excluding any payment or distribution of securities of the Company provided for
by a plan of reorganization or readjustment authorized by an order or decree of
a court of competent jurisdiction in a reorganization proceeding under any
applicable Bankruptcy Law or of any other corporation provided for by such plan
of reorganization or readjustment which securities are subordinated in right of
payment to all then outstanding Senior Indebtedness to substantially the same
extent as the Securities are so subordinated as provided in this Article) shall
be paid by the liquidating trustee or agent or other person making such payment
or distribution, whether a trustee in bankruptcy, a receiver or liquidating
trustee or otherwise, directly to the holders of Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, ratably according to the aggregate amounts remaining
unpaid on account of the principal of, premium, if any, interest or additional
amounts required in respect of certain taxes, and any interest thereon, on the
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in full of all Senior Indebtedness remaining unpaid, after giving effect
to any concurrent payment or distribution to the holders of such Senior
Indebtedness; and

                  (c) in the event that, notwithstanding the foregoing, any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, shall be received by the Trustee or the
Holders of the Securities before all Senior Indebtedness is paid in full, then,
and in such event such payment or distribution shall be paid over to the holders
of such Senior Indebtedness or their representative or representatives or to the
trustee or trustees under any indenture under which any instruments evidencing
any of such Senior Indebtedness may have been issued, ratably as aforesaid, for
application to the payment of all Senior Indebtedness remaining unpaid until all
such Senior Indebtedness shall have been paid in full, after giving effect to
any concurrent payment or distribution to the holders of such Senior
Indebtedness. As used in this Article, the phrase "payment in full" (or any
similar phrase), when used to refer to the payment of Senior Indebtedness, shall
mean payment in full of the aggregate amount of such Senior Indebtedness then
outstanding in cash, securities or other property.

            The consolidation of the Company with, or the merger of the Company
with or into, another Person or the liquidation or dissolution of the Company
following the conveyance or transfer of all or substantially all of its
properties and assets as an entirety to another Person

                                       72
<PAGE>

upon the terms and conditions set forth in Article VII shall not be deemed a
Proceeding for the purposes of this Section if the Person formed by such
consolidation with or into which the Company is merged or the Person which
acquires by conveyance or transfer such properties and assets as an entirety, as
the case may be, shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions set forth in Article VII.

            SECTION 12.03 PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION
OF SECURITIES. In the event that any Securities of a series are declared due and
payable before their Stated Maturity, then and in such event the holders of the
Senior Indebtedness outstanding at the time such Securities so become due and
payable shall be entitled to receive payment in full of all amounts due on or in
respect of such Senior Indebtedness (including any amounts due upon
acceleration), or provision shall be made for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character, whether in cash, properties or
securities (including any Junior Subordinated Payment) by the Company on account
of the principal of, or premium, if any, or any interest or Additional Amounts
on such Securities or on account of the purchase or other acquisition of such
Securities by the Company or any Subsidiary of the Company.

            In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, then and in such event such payment shall
be paid over and delivered forthwith to the Company.

            The provisions of this Section shall not apply to any payment with
respect to which Section 12.02 would be applicable.

            SECTION 12.04 NO PAYMENT ON SECURITIES IN EVENT OF DEFAULT ON SENIOR
INDEBTEDNESS. In the event and during the continuation of (i) a Company default
in the payment of any principal, interest, if any or premium, if any, or any
Additional Amounts on any Senior Indebtedness when the same becomes due and
payable, whether at maturity or at a date fixed for prepayment or declaration or
otherwise or (ii) an event of default with respect to any Senior Indebtedness
permitting the holders thereof to accelerate the maturity thereof and written
notice of such event of default (requesting that payments on the Securities
cease) is given to the Company by the holders of Senior Indebtedness, then
unless and until such default in payment or event of default shall have been
cured or waived or shall have ceased to exist, no direct or indirect payment (in
cash, property or securities, by set-off or otherwise) shall be made or agreed
to be made on account of the Junior Subordinated Debt or interest thereon or in
respect of any repayment, redemption, retirement, purchase or other acquisition
of Junior Subordinated Debt.

            In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

                                       73
<PAGE>

            The provisions of this Section shall not apply to any payment with
respect to which Section 12.02 would be applicable.

            SECTION 12.05 PAYMENTS ON SECURITIES PERMITTED. Nothing contained in
this Indenture or in any of the Securities shall (a) affect the obligation of
the Company to make, or prevent the Company from making, at any time except
during the pendency of any Proceeding referred to in Section 12.02 or under the
conditions described in Sections 12.03 and 12.04, payments of principal,
premium, interest or Additional Amounts, and any interest thereon, of or on the
Securities or (b) prevent the application by the Trustee of any moneys deposited
with it hereunder to the payment of or on account of the principal, premium,
interest or Additional Amounts, and any interest thereon, of or on the
Securities unless the Trustee shall have received at its Corporate Trust Office
written notice of any event prohibiting the making of such payment more than two
Business Days prior to the date fixed for such payment or prior to the execution
of an instrument to satisfy and discharge this Indenture based upon the deposit
of funds under Section 4.01(l)(B).

            SECTION 12.06 SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR
INDEBTEDNESS. Subject to the payment in full of all amounts due or to become due
on all Senior Indebtedness, or the provision for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, the Holders of the Securities shall be subrogated to the extent of
the payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article (equally and ratably with the holders
of all indebtedness of the Company which by its express terms is subordinated to
Senior Indebtedness of the Company to substantially the same extent as the
Securities are subordinated to the Senior Indebtedness and is entitled to like
rights of subrogation by reason of any payments or distributions made to holders
of such Senior Indebtedness) to all of the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of (and
premium, if any) and any interest and Additional Amounts on the Securities shall
be paid in full. For purposes of such subrogation or assignment, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebtedness
by Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

            SECTION 12.07 PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities any series on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in any Securities of
any series is intended to or shall (a) impair, as between the Company and the
Holders of the Securities of a series, the obligations of the Company, which are
absolute and unconditional, to pay to the Holders of the Securities the
principal of , premium, if any, and any interest and Additional Amounts on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than their rights
in relation to

                                       74

the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture including, without limitation, filing and
voting claims in any Proceeding, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

            SECTION 12.08 AUTHORIZATION OF HOLDERS OF SECURITIES TO TRUSTEE TO
EFFECT SUBORDINATION. Each Holder of Securities by his acceptance thereof
authorizes and directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article and appoints the Trustee his attorney-in-fact for any and all such
purposes.

            SECTION 12.09 NOTICES TO TRUSTEE. The Company shall give prompt
written notice to a Responsible Officer of the Trustee located at the Corporate
Trust Office of the Trustee of any fact known to the Company which would prevent
the making of any payment to or by the Trustee in respect of the Securities.
Notwithstanding the provisions of this Article or any other provisions of this
Indenture, neither the Trustee nor any Paying Agent (other than the Company)
shall be charged with knowledge of the existence of any Senior Indebtedness or
of any event which would prohibit the making of any payment of moneys to or by
the Trustee or such Paying Agent, unless and until the Trustee or such Paying
Agent shall have received (in the case of the Trustee, at its Corporate Trust
Office) written notice thereof from the Company or from the holder of any Senior
Indebtedness or from the trustee for any such holder, together with proof
satisfactory to the Trustee of such holding of Senior Indebtedness or of the
authority of such trustee; provided, however, that if at least two Business Days
prior to the date upon which by the terms hereof any such moneys may become
payable for any purpose (including, without limitation, the payment of the
principal, premium, interest or Additional Amounts, of or on any Security, or
any interest thereon) or the date on which the Trustee shall execute an
instrument acknowledging satisfaction and discharge of this Indenture, the
Trustee shall not have received with respect to such moneys or the moneys
deposited with it as a condition to such satisfaction and discharge the notice
provided for in this Section 12.09, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary, which may be
received by it on or after such two Business Days prior to such date. The
Trustee shall be entitled to rely on the delivery to it of a written notice by a
person representing himself to be a holder of Senior Indebtedness (or a trustee
on behalf of such holder) to establish that such a notice has been given by a
holder of Senior Indebtedness or a trustee on behalf of any such holder. In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

            SECTION 12.10 TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS. The Trustee
shall be entitled to all the rights set forth in this Article in respect of any
Senior Indebtedness at any time held by it to the same extent as any other
holder of Senior Indebtedness and nothing in this Indenture shall be construed
to deprive the Trustee of any of its rights as such holder.

            SECTION 12.11 NO WAIVER OF SUBORDINATION PROVISIONS. No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

            Without in any way limiting the generality of the immediately
preceding paragraph, the holders of Senior Indebtedness may, at any time and
from time to time, without the consent of or notice to the Trustee or the
Holders of the Securities, without incurring responsibility to such Holders of
the Securities and without impairing or releasing the subordination provided in
this Article or the obligations hereunder of such Holders of the Securities to
the holders of Senior Indebtedness, do any one or more of the following: (i)
change the manner, place or terms of payment or extend the time of payment of,
or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (iii) release any Person liable in any manner for
the collection of Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

            SECTION 12.12 RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF
LIQUIDATING AGENT. Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee, subject to the provisions of Article
VI, and the Holders of the Securities shall be entitled to rely upon any order
or decree entered by any court of competent jurisdiction in which such
Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

            SECTION 12.13 TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS. The Trustee, in its capacity as trustee under this Indenture,
shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness and shall not be liable to any such holders if it shall in good
faith mistakenly pay over or distribute to Holders of Securities or to the
Company or to any other Person cash, property or securities to which any holders
of Senior Indebtedness shall be entitled by virtue of this Article or otherwise.

            SECTION 12.14 ARTICLE APPLICABLE TO PAYING AGENTS. In case at any
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee.

            SECTION 12.15 CERTAIN CONVERSIONS OR EXCHANGES DEEMED PAYMENT. For
the purposes of this Article only, (a) the issuance and delivery of junior
securities upon exchange of Securities shall not be deemed to constitute a
payment or distribution on account of the principal of , premium, if any, or any
interest or Additional Amounts, on Securities or on account of the purchase or
other acquisition of Securities, and (b) the payment, issuance or delivery of
cash, property or securities (other than junior securities) upon exchange of a
Security shall be deemed to constitute payment on account of the principal of
such security. For the purposes of this Section, the term "junior securities"
means (i) shares of any stock of any class of the Company and (ii) securities of
the Company which are subordinated in right of payment to all Senior
Indebtedness which may be outstanding at the time of issuance or delivery of
such securities to substantially the same extent as, or to a greater extent
than, Securities are so subordinated as provided in this Article.

            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.

passu with, or subordinated to, the Securities, provided, however, that Senior

            SECTION 1.04. Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given to or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments is or are
delivered to the Trustee, and, where it is hereby expressly required, to the
Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Company and any agent of the Trustee or the Company, if made
in the manner provided in this Section.

such instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any 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 Person acting in other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority.

                  (c) The fact and date of the execution by any Person of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which the Trustee deems sufficient and in
accordance with such reasonable rules as the Trustee may determine.

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

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done 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) The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled to take any
action under this Indenture by vote or consent. Except as otherwise provided
herein, such record date shall be the later of 30 days prior to the first
solicitation of such consent or vote or the date of the most recent list of
Securityholders furnished to the Trustee pursuant to Section 701 prior to such
solicitation. If a record date is fixed, those persons who were Securityholders
at such record date (or their duly designated proxies), and only those persons,
shall be entitled to take such action by vote or consent or to revoke any vote
or consent previously given, whether or not such persons continue to be Holders
after such record date, provided, however, that unless such vote or consent is
obtained from the Holders (or their duly designated proxies) of the requisite
principal amount of Outstanding Securities prior to the date which is the 120th
day after such record date, any such vote or consent previously given shall
automatically and without further action by any Holder be canceled and of no
further effect.

            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,

                        (1) the Trustee by any Holder or by the Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing (which may be via facsimile) to or with the Trustee at its
      Corporate Trust office, or

                        (2) the Company by the Trustee or by any Holder shall be
      sufficient for every purpose (except as otherwise provided in Section 5.01
      hereof) hereunder if in writing and mailed, first class, postage prepaid,
      to the Company addressed to it at the address of its principal office
      specified in the first paragraph of this instrument or at any other
      address previously furnished in writing to the Trustee by the Company.

            SECTION 1.06. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed,
first class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Securities Register, not later than
the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

            SECTION 1.07. Conflict With Trust Indenture Act. If any provision of
this Indenture limits, qualifies or conflicts with the duties imposed by any of
Sections 3.10 to 3.17, inclusive, of the Trust Indenture Act through operation
of Section 3.18(c) thereof, such imposed duties shall control.

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

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

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

be governed by and construed in accordance with the laws of the State of New
York.

            SECTION 1.13. Non-Business Days. In any case where any Interest
Payment Date or Stated Maturity of any Security shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or the Securities)
payment of interest or principal need not be made on such date, but may be made
on the next succeeding Business Day and no interest shall accrue for the period
from and after such Interest Payment Date or Stated Maturity, as the case may
be, until the next succeeding Business Day, in each case with the same force and
effect as if made on the Interest Payment Date or at the Stated Maturity, except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day.

30-day months and a 360-day year. The amount of interest payable for any partial
period shall be computed on the basis of the number of days elapsed in a 360-day
year of twelve 30-day months. In the event that any date on which interest is
payable on this Security is not a Business Day, then a payment of the interest
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case

payable. A "Business Day" shall mean any day other than a day on which banking
institutions in the City of New York are authorized or required by law or
executive order to remain closed or a day on which the Corporate Trust Office of
the Trustee [if applicable, insert-, or the principal office of the Property
Trustee under the Trust Agreement hereinafter referred to for AmerUs Capital

[close of business on the Business Day] next preceding such Interest Payment
Date. Any such interest installment not so punctually paid or duly provided for

and may either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

            [If applicable, insert- The Company shall have the right at any time
during the term of this Security, from time to time, to extend the interest
payment period of such Security for up to __ consecutive [months] [quarters]
with respect to each deferral period (each an "Extension Period"), during which
periods the Company shall have the right to make partial payments of interest on
any Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided that during any such Extension
Period, the Company will not, and will not permit any Subsidiary of the Company
to (i) declare or pay any dividends or distributions or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the Company's
outstanding capital stock or (ii) make any payment of principal, interest or

under any employee or agent benefit plans or its satisfaction of its obligations
pursuant to any contract or security outstanding on the date of the event

reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the Company's capital stock for another class or series
of its capital stock, (3) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of the
capital stock or the security being converted or exchanged, (4) dividends or
distributions in our common stock (or rights to acquire capital stock) or
repurchases or redemptions of capital stock solely from the issuance or exchange
of capital stock, or (5) redemptions or repurchases of any rights outstanding
under a shareholder rights plan. Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period, provided
that such Extension Period together with all such previous and further
extensions of such Extension Period, shall not exceed __ consecutive [months]
[quarters] or extend beyond the Maturity of this Security. Upon the termination
of any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due, the Company may select a new
Extension Period, subject to the above requirements. No interest shall be due
and payable during an Extension Period except at the end thereof. The Company
shall give the Holder of this Security and the Trustee notice of its selection
of an Extension Period at least one Business Day prior to the Interest Payment
Date [if applicable, insert- the earlier of (i) the date the Distributions on
the Preferred Securities are payable or (ii) the date the Administrative
Trustees are required to give notice to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date.

this Security will be made at the office or agency of the Company maintained for
that purpose in the United States, in such coin or currency of the United States
of America as at the time of payment is legal tender for payment of public and
private debts [if applicable, insert-; provided, however, that at the option of
the Company payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Securities
Register or (ii) by wire transfer in immediately available funds at such place
and to such account as may be designated by the Person entitled thereto as
specified in the Securities Register].

            The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and subject in right of payments to the
prior payment in full of all Senior Debt, and this Security is issued subject to
the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Debt, whether now outstanding or hereafter incurred,
and waives reliance by each such holder upon said provisions.

<PAGE>

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

            Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the 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 after the execution and delivery of this Indenture, the Company may deliver
Securities executed by the Company to the Trustee for authentication. Securities
may be authenticated on original issuance from time to time and delivered
pursuant to such procedures acceptable to the Trustee ("Procedures") as may be
specified from time to time by Company Order. Procedures may authorize
authentication and delivery pursuant to oral instructions of the Company or a
duly authorized agent, which instructions shall be promptly confirmed in
writing.

            Prior to the delivery of a Security in any such form to the Trustee
for authentication, the Company shall deliver to the Trustee the following:

                  (a) A Company Order requesting the Trustee's authentication
and delivery of all or a portion of the Securities of such series, and if less
than all, setting forth procedures for such authentication;

                  (b) The Board Resolution by or pursuant to which such form of
Security has been approved, and the Board Resolution, if any, by or pursuant to

taken;

                  (c) An Officers' Certificate dated the date such certificate
is delivered to the Trustee, stating that all conditions precedent provided for
in this Indenture relating to the authentication and delivery of Securities in
such form and with such terms have been complied with; and

                  (d) An Opinion of Counsel stating that (i) the form of such
Securities has been duly authorized and approved in conformity with the
provisions of this Indenture; (ii) the terms of such Securities have been duly
authorized and determined in conformity with the provisions of this Indenture,
or, if such terms are to be determined pursuant to Procedures, when so
determined such terms shall have been duly authorized and determined in
conformity with the provisions of this Indenture; and (iii) Securities in such
form when completed by appropriate insertions and executed and delivered by the
Company to the Trustee for authentication in accordance with this Indenture,
authenticated and delivered by the Trustee in accordance with this Indenture
within the authorization as to aggregate principal amount established from time

opinion of Counsel, will be the legal, valid and binding obligations of the
Company entitled to the benefits of this Indenture, subject to applicable
bankruptcy, reorganization, insolvency and similar laws generally affecting
creditors' rights, to general equitable principles except 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

                                       22

<PAGE>

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 and subject to such other qualifications as such counsel shall
conclude do not materially affect the rights of Holders of such Securities;
provided, however, that the Trustee shall be entitled to receive the documents
referred to in Clauses (b), (c) and (d) above only at or prior to the first
request of the Company to the Trustee to authenticate Securities of such series.

            Each Security shall be dated the date of its authentication.

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

            SECTION 3.04. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute, and upon Company
Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
denomination, substantially of the tenor of the definitive Securities of such
series in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities.

            If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay. After the preparation of definitive Securities, the temporary Securities
shall be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, 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 having the
same Original Issue Date and Stated Maturity and having the same terms as such
temporary Securities. Until so exchanged, the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

            SECTION 3.05. Registration, Transfer and Exchange. The Company shall
cause to be kept at the Corporate Trust Office of the Trustee a register in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities.
Such register is herein sometimes referred to as the "Securities Register." The
Trustee is hereby appointed "Securities Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

            Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new

                                       23

<PAGE>

Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same original Issue Date and Stated Maturity
and having the same terms.

            At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any securities are so surrendered for exchange,
the Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

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

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

            No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities, other than exchanges pursuant to
Section 304, 906 or 1106.

            Notwithstanding any of the foregoing, any Global Security of a
series shall be exchangeable pursuant to this Section 305 for Securities
registered in the names of Persons other than the Depositary for such Security
or its nominee only if (i) such Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Security or if at
any time such Depositary ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (ii) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series. Any Global Security that
is exchangeable pursuant to the preceding sentence shall be exchangeable for
Securities registered in such names as such Depositary shall direct.

            Notwithstanding any other provision in this Indenture, a Global
Security may not be transferred except as a whole by the Depositary with respect
to such Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

            Neither the Company nor the Trustee shall be required, pursuant to
the provisions of this Section, (a) to issue, transfer or exchange any Security
of any series during a period beginning at the opening of business 15 days
before the day of selection for redemption of Securities pursuant to Article
Eleven and ending at the close of business on the day of mailing of notice of
redemption or (b) to transfer or exchange any Security so selected for
redemption in whole or in part, except, in the case of any Security to be
redeemed in part, any portion thereof not to be redeemed.

            SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities. If
any mutilated Security is surrendered to the Trustee together with 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 in exchange therefor a new Security of the same issue and series of like
tenor and principal amount, having the same Original Issue Date and Stated
Maturity and bearing the same Interest Rate as such mutilated Security, and
bearing a number not contemporaneously outstanding.

            If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
issuing Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same issue and series of like tenor and
principal amount, having the same Original Issue Date and Stated Maturity and
bearing the same Interest Rate as such destroyed, lost or stolen Security, and
bearing a number not contemporaneously outstanding.

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

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

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

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

            SECTION 3.07. Payment of Interest; Interest Rights Preserved.
Interest on any Security of any series which is payable, and is punctually paid
or duly provided for, on any Interest Payment Date, shall be paid to the Person
in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest
in respect of Securities of such series, except that, unless otherwise provided
in the Securities of such series, interest payable on the Stated Maturity of a
Security shall be paid to the Person to whom principal is paid. The initial
payment of interest on any Security of any series which is issued between a
Regular Record Date and the related Interest Payment Date shall be payable as
provided in such Security or in the Board Resolution pursuant to Section 3.01
with respect to the related series of Securities.

                                       25

<PAGE>

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

                        (1) The Company may elect to make payment of any
      Defaulted Interest to the Persons in whose names the Securities of such
      series in respect of which interest is in default (or their respective
      Predecessor Securities) are registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security and the date of the proposed payment, and at the same
      time the Company shall deposit with the Trustee an amount of money equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest or shall make arrangements satisfactory to the Trustee for such
      deposit prior to the date of the proposed payment, such money when
      deposited to be held in trust for the benefit of the Persons entitled to
      such Defaulted Interest as in this Clause provided. Thereupon the Trustee
      shall fix a Special Record Date for the payment of such Defaulted Interest
      which shall be not more than 15 days and not less than 10 days prior to
      the date of the proposed payment and not less than 10 days after the
      receipt by the Trustee of the notice of the proposed payment. The Trustee
      shall promptly notify the Company of such Special Record Date and, in the
      name and at the expense of the Company, shall cause notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor to
      be mailed, first class, postage prepaid, to each Holder of a Security of
      such series at the address of such Holder as it appears in the Securities
      Register not less than 10 days prior to such Special Record Date. The
      Trustee may, in its discretion, in the name and at the expense of the
      Company, cause a similar notice to be published at least once in a
      newspaper, customarily published in the English language on each Business
      Day and of general circulation in the Borough of Manhattan, The City of
      New York, but such publication shall not be a condition precedent to the
      establishment of such Special Record Date. Notice of the proposed payment
      of such Defaulted Interest and the Special Record Date therefor having
      been mailed as aforesaid, such Defaulted Interest shall be paid to the
      Persons in whose names the Securities of such series (or their respective
      Predecessor Securities) are registered on such Special Record Date and
      shall no longer be payable pursuant to the following Clause (2).

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

            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon 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.

                                       26

            SECTION 3.08. Persons Deemed Owners. The Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name any
Security is registered as the owner of such Security for the purpose of
receiving payment of principal of and (subject to Section 3.07) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

            SECTION 3.09. Cancellation. All Securities surrendered for payment,
redemption, transfer or exchange shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee, and any such Securities and Securities
surrendered directly to the Trustee for any such purpose shall be promptly
canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities shall be disposed of by the Trustee and upon written request therefor
the Trustee shall deliver to the Company a certificate of such disposal.

            SECTION 3.10. Computation of Interest. Except as otherwise specified
as contemplated by Section 3.01 for Securities of any series, interest on the
Securities of each series shall be computed on the basis of a 360-day year of
twelve 30-day months and interest on the Securities of each series for any
partial period shall be computed on the basis of the number of days elapsed in a
360-day year of twelve 30-day months.

            SECTION 3.11. Deferrals of Interest Payment Dates. If specified as
contemplated by Section 301 with respect to the Securities of a particular
series, the Company shall have the right, at any time during the term of such
series, from time to time to extend the interest payment period for such
Securities for such period or periods as may be specified as contemplated by
Section 301 (each, an "Extension Period") during which periods the Company shall
have the right to make partial payments of interest on any Interest Payment
Date, and at the end of such Extension Period the Company shall pay all interest
then accrued and unpaid thereon (together with Additional Interest thereon, if
any, at the rate specified for the Securities of such series to the extent
permitted by applicable law), provided, however, that during any such Extension
Period, the Company shall not, and shall cause any Subsidiary not to, (i)
declare or pay any dividends or distributions on, or redeem, purchase, acquire
or make a liquidation payment with respect to, any of the Company's capital
stock, or (ii) make any payment of principal, interest or premium, if any, on or
repay, repurchase or redeem any debt securities that rank pari passu with or
junior in interest to the Securities of such series or make any guarantee
payments with respect to the foregoing (other than (a) purchases or acquisitions
of our common stock in connection with our satisfaction of our obligations under
any employee or agent benefit plans or our satisfaction of our obligations
pursuant to any contract or security outstanding on the date of the event
requiring us to purchase our common stock, (b) as a result of a reclassification
of our capital stock or the exchange or conversion of one class or series of our
capital stock for another class or series of our capital stock, (c) the purchase
of fractional interests in shares of our capital stock pursuant to the
conversion or exchange provisions of the capital stock or the security being
converted or exchanged, (d) dividends or distributions in our common stock (or
rights to acquire capital stock) or repurchases or redemptions of capital stock
solely from the issuance or exchange of capital stock or

                                       27

<PAGE>

(e) redemptions or repurchases of any rights outstanding under a shareholder
rights plan). Prior to the termination of any such Extension Period, the Company
may further extend the interest payment period, provided that such Extension
Period together with all such previous and further extensions of such Extension
Period shall not exceed the period or periods so specified or extend beyond the
Maturity of such Securities. Upon termination of any Extension Period and upon
the payment of all accrued and unpaid interest and any Additional Interest then
due, the Company may select a new Extension Period, subject to the above
requirements. No interest shall be due and payable during an Extension Period,
except at the end thereof. The Company shall give the Holders of the Securities
of such series and the Trustee notice of its selection of such Extension Period
at least one Business Day prior to the Interest Payment Date or, with respect to
the Securities of a series issued to an AmerUs Trust, prior to the earlier of
(i) the date the Distributions on the Preferred Securities of such AmerUs Trust
are payable or (ii) the date the Administrative Trustees of such AmerUs Trust
are required to give notice to the New York Stock Exchange or other applicable
self-regulatory organization or to holders of such Preferred Securities of the
record date or the date such Distributions are payable, but in any event not
less than one Business Day prior to such record date.

            The Trustee shall promptly give notice of the Company's selection of
such Extension Period to the Holders of the outstanding Securities of such
series.

            SECTION 3.12. Right of Set-Off. With respect to the Securities of a
series issued to an AmerUs Trust, notwithstanding anything to the contrary in
the Indenture, the Company shall have the right to set-off any payment it is
otherwise required to make thereunder in respect of any such Security to the
extent the Company has theretofore made, or is concurrently on the date of such
payment making, a payment under the AmerUs Guarantee relating to such Security
or a payment to any Holder of a corresponding series of Preferred Securities in
connection with a suit instituted pursuant to Section 5.08.

            SECTION 3.13. Agreed Tax Treatment. Each Security issued hereunder
shall provide that the Company and, by its acceptance of a Security or a
beneficial interest therein, the Holder of, and any Person that acquires a
beneficial interest in, such Security agree that for United States Federal,
state and local tax purposes it is intended that such Security constitute
indebtedness.

            SECTION 3.14. Extension of Stated Maturity; Adjustment of Stated
Maturity Upon an Exchange. If specified as contemplated by Section 202 with
respect to the Securities of a particular series, the Company shall have the
right to (a) change the Maturity Date of the Securities of such series upon the
liquidation of an AmerUs Trust and the exchange of such Securities for the
Preferred Securities of such AmerUs Trust and (b) extend the Stated Maturity for
the Securities of such series; provided, that at time any election to extend the
Maturity Date is made and at the time of such extension, (i) the Company is not
in bankruptcy, otherwise insolvent or in liquidation, (ii) the Company is not in
default in the payment of any interest or principal on the Securities of such
series and no deferred interest payments thereon have accrued, (iii) the
applicable AmerUs Trust is not in arrears on payments of Distributions on its
Preferred Securities and no deferred Distributions thereon are accumulated, (iv)
the Securities are rated not less than ____ by Standard & Poor's Ratings
Services or ____ by Moody's Investors Service, Inc. or the equivalent by any
other nationally recognized statistical rating organization and (v) the extended
Stated Maturity

                                       28
<PAGE>
is no later than the 49th anniversary of the initial issuance of the Preferred
Securities of the applicable AmerUs Trust; provided, further, that, if the
Company exercises its right to liquidate the AmerUs Trust and exchange the
Securities of such series for the Preferred Securities of such AmerUs Trust as
specified in clause (a) above, any changed Stated Maturity of the Securities of
such series shall be no earlier than the date that is five years after the
issuance of the Preferred Securities and no later than the date 30 years (plus
an extended term of up to an additional 19 years if the above-referenced
conditions are satisfied) after the date of the initial issuance of the
Preferred Securities of the applicable AmerUs Trust.

            SECTION 3.15. CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to 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.

                                   ARTICLE IV
                     SATISFACTION, DISCHARGE AND DEFEASANCE

            SECTION 4.01. Satisfaction and Discharge of Indenture. This
Indenture shall cease to be of further effect (except as to (i) any surviving
rights of transfer, substitution and exchange of Securities, (ii) rights
hereunder of Holders to receive payments of principal of (and premium, if any)
and interest on the Securities and other rights, duties and obligations of the
Holders as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (iii) the rights and obligations of the Trustee
hereunder), and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture, when

                        (1) either

                              (A) all Securities theretofore authenticated and
      delivered (other than (i) Securities which have been destroyed, lost or
      stolen and which have been replaced or paid as provided in Section 306 and
      (ii) Securities 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 1003)
      have been delivered to the Trustee for cancellation; or

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

                        (i) have become due and payable, or (ii) will become due
      and payable at their Stated Maturity within one year of the date of
      deposit, and the Company, in the case of (i) or (ii) above, has deposited
      or caused to be deposited with the Trustee as trust funds in trust for
      such purpose an amount in the currency or currencies in which the
      Securities of such series are payable sufficient

                                       29

<PAGE>
      to pay and discharge the entire indebtedness on such Securities not
      theretofore delivered to the Trustee for cancellation, for principal (and
      premium, if any) and interest (including any Additional Interest) to the
      date of such deposit (in the case of Securities which have become due and
      payable) or to the Stated Maturity;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07 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 10.03 shall survive such satisfaction and discharge.

            SECTION 4.02. Application of Trust Money. Subject to the provisions
of the last paragraph of Section 10.03, all money deposited with the Trustee
pursuant to Section 4.01 or money or government Obligations deposited with the
Trustee pursuant to Section 4.03, or received by the Trustee in respect of
Government Obligations deposited with the Trustee pursuant to Section 403, shall
be held in trust and applied by it, in accordance with the provisions of the
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money or obligations have
been deposited with or received by the Trustee; provided, however, such moneys
need not be segregated from other funds except to the extent required by law.

            SECTION 4.03. Satisfaction, Discharge and Defeasance of Securities
of Any Series. Unless otherwise provided in the Board Resolution adopted
pursuant to Section 3.1 establishing the terms of the Securities of any series,
the Company shall be deemed to have paid and discharged the entire indebtedness
on all the Outstanding Securities of any such series and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of such indebtedness, when

                        (1) with respect to all Outstanding Securities of such
      series,

                              (A) the Company has irrevocably deposited or
      caused to be irrevocably deposited with the Trustee as trust funds in
      trust for such purpose an amount sufficient to pay and discharge the
      entire indebtedness on all Outstanding Securities of such series for
      principal (and premium, if any) and interest (including any Additional
      Interest) to the Stated Maturity or any Redemption Date as contemplated by
      the penultimate paragraph of this Section 403, as the case may be; or

                              (B) the Company has irrevocably deposited or
      caused to be irrevocably deposited with the Trustee as obligations in
      trust for such purpose an amount of Government Obligations as will, in the
      written opinion of independent public accountants

                                       30
<PAGE>
      delivered to the Trustee, together with predetermined and certain income
      to accrue thereon, without consideration of any reinvestment thereof, be
      sufficient to pay and discharge when due the entire indebtedness on all
      Outstanding Securities of such series for principal (and premium, if any)
      and interest (including any Additional Interest) to the Stated Maturity or
      any Redemption Date as contemplated by the penultimate paragraph of this
      Section 403, as the case may be; and

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

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

            Any deposits with the Trustee referred to in Section 4.03(i) above
shall be irrevocable and shall be made under the terms of an escrow trust
agreement in form and substance reasonably satisfactory to the Trustee. If any
Outstanding Securities of such series are to be redeemed prior to their Stated
Maturity, whether pursuant to any optional redemption provisions or in
accordance with any mandatory sinking fund requirement, the applicable escrow
trust agreement shall provide therefor and the Company shall make such
arrangements as are satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company. If
the Securities of such series are not to become due and payable at their Stated
Maturity or upon call for redemption within one year of the date of deposit,
then the Company shall give, not later than the date of such deposit, notice of
such deposit to the Holders of Securities of such series.

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

                                    ARTICLE V
                                    REMEDIES

            SECTION 5.01. Events of Default. "Event of Default", wherever used
herein with respect to the Securities of any series, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):

                        (1) default in the payment of any interest upon any
      Security of that series, including any Additional Interest in respect
      thereof, when it becomes due and

                                       31

<PAGE>

      payable, and continuance of such default for a period of 30 days (subject
      to the deferral of any due date in the case of an Extension Period); or

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

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

                        (4) the entry of a decree or order by a court having
      jurisdiction in the premises adjudging the Company a bankrupt or
      insolvent, or approving as properly filed a petition seeking
      reorganization, arrangement, adjustment or composition of or in respect of
      the Company under any applicable Federal or State bankruptcy, insolvency,
      reorganization or other similar law, or appointing a receiver, liquidator,
      assignee, trustee, sequestrator (or other similar official) of the Company
      or of any substantial part of its property or ordering the winding up or
      liquidation of its affairs, and the continuance of any such decree or
      order unstayed and in effect for a period of 60 consecutive days; or

                        (5) the institution by the Company of proceedings to be
      adjudicated a bankrupt or insolvent, or the consent by it to the
      institution of bankruptcy or insolvency proceedings against it, or the
      filing by it of a petition or answer or consent seeking reorganization or
      relief under any applicable Federal or State bankruptcy, insolvency,
      reorganization or other similar law, or the consent by it to the filing of
      any such petition or to the appointment of a receiver, liquidator,
      assignee, trustee, sequestrator (or other similar official) of the Company
      or of any substantial part of its property, or the making by it of an
      assignment for the benefit of creditors, or the admission by it in writing
      of its inability to pay its debts generally as they become due and its
      willingness to be adjudicated a bankrupt, or the taking of corporate
      action by the Company in furtherance of any such action; or

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

            SECTION 5.02. Acceleration of Maturity; Rescission and Annulment. If
an Event of Default (other than an Event of Default specified in Section 5.01(4)
or 5.01(5)) with respect to Securities of any series at the time Outstanding
occurs and is continuing, then and in every such case the Trustee or the Holders
of not less than 25% in principal amount of the Outstanding Securities of that
series may declare the principal amount (or, if the Securities of that series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of that series) of all the Securities of that
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), provided that, in the

                                       32

<PAGE>

case of the Securities of a series issued to an AmerUs Trust, if upon an Event
of Default, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Securities of that series fail to declare the principal of
all the Securities of that series to be immediately due and payable, the holders
of at least 25% in aggregate liquidation amount of the corresponding series of
Preferred Securities then outstanding shall have such right by a notice in
writing to the Company and the Trustee; and upon any such declaration such
principal amount (or specified amount) of and the accrued interest (including
any Additional Interest) on all the Securities of such series shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on such Securities shall remain subordinated
to the extent provided in Article Thirteen. If an Event of Default specified in
Section 5.01(4) or 5.01(5) with respect to Securities at the time Outstanding
occurs, the principal amount on all the Securities shall automatically, and
without any declaration or other action on the part of the Trustee or any
Holder, become immediately due and payable.

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

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

                              (A) all overdue installments of interest
      (including any Additional Interest) on all Securities of that series,

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

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

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

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

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

            Upon receipt by the Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, with respect to Securities of
a series all or part of which is represented by a Global Security, a record date
shall be established for determining Holders of

                                       33

<PAGE>
Outstanding Securities of such series entitled to join in such notice, which
record date shall be at the close of business on the day the Trustee receives
such notice. The Holders on such record date, or their duly designated proxies,
and only such Persons, shall be entitled to join in such notice, whether or not
such Holders remain Holders after such record date; provided, that, unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having joined
in such notice prior to the day which is 90 days after such record date, such
notice of declaration of acceleration, or rescission and annulment, as the case
may be, shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
written notice of declaration of acceleration, or rescission and annulment
thereof, as the case may be, that is identical to a written notice which has
been canceled pursuant to the proviso to the preceding sentence, in which event
a new record date shall be established pursuant to the provisions of this
Section 5.02.

            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 installment of
      interest (including any Additional Interest) on any Security when such
      interest becomes due and payable and such default continues for a period
      of 30 days, or

                        (2) default is made in the payment of the principal of
      (and 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, the whole amount then due and payable on
      such Securities for principal, including any sinking fund payment or
      analogous obligations (and premium, if any) and interest (including any
      Additional Interest), including, to the extent that payment of such
      interest shall be lawful, interest on any overdue principal (and premium
      if any) and on any overdue installments of interest (including any
      Additional Interest) at the rate borne by the Securities; and, in addition
      thereto, all amounts owing the Trustee under Section 6.07.

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

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

                                       34

            SECTION 5.04. Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors,

                  (a) the Trustee (irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal (and
premium, if any) or interest (including any Additional Interest)) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

                        (i) to file and prove a claim for the whole amount of
      principal (and premium, if any) and interest (including any Additional
      Interest) owing and unpaid in respect to the Securities and to file such
      other papers or documents as may be necessary or advisable and to take any
      and all actions as are authorized under the Trust Indenture Act in order
      to have the claims of the Holders and any predecessor to the Trustee under
      Section 607 and of the Holders allowed in any such judicial proceedings;
      and

                        (ii) and 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 in accordance with Section
      506; and

                  (b) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.06, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.07.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

            SECTION 5.05. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.07, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

            SECTION 5.06. Application of Money Collected. Any money or property
collected or to be applied by the Trustee with respect to a series of Securities
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money or
property on account of principal (or premium, if any) or interest

                                       35

<PAGE>

(including any Additional Interest), upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

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

            SECOND: To the payment of the amounts then due and unpaid upon such
series of Securities for principal (and premium, if any) and interest (including
any Additional Interest), in respect of which or for the benefit of which such
money has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on such series of Securities for
principal (and premium, if any) and interest (including any Additional
Interest), respectively; and

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

            SECTION 5.07. Limitation on Suits. No Holder of any Securities of
any series shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture or for the appointment of a receiver,
assignee, trustee, liquidator, sequestrator (or other similar official) or for
any other remedy hereunder, unless:

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

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

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

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

                        (5) no direction inconsistent with such written request
      has been given to the Trustee during such 60-day period by the Holders of
      a majority in principal amount of the Outstanding Securities of that
      series; it being understood and intended that no one or more of such
      Holders shall have any right in any manner whatever by virtue of, or by
      availing of, any provision of this Indenture to affect, disturb or
      prejudice the rights of any other Holders of Securities, or to obtain or
      to seek to obtain priority or preference over any other of such Holders or
      to enforce any right under this Indenture, except in the manner herein
      provided and for the equal and ratable benefit of all such Holders.

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

                                       36

<PAGE>

such Security on the respective Stated Maturities expressed in such Security and
to institute suit for the enforcement of any such payment, and such right shall
not be impaired without the consent of such Holder. In the case of Securities of
a series issued to a AmerUs Trust, any holder of the corresponding series of
Preferred Securities shall have the right upon the occurrence of an Event of
Default described in Section 5.01(1) or 5.01(2) hereof, to institute a suit
directly against the Company for enforcement of payment to such Holder of
principal of (premium, if any) and (subject to Section 3.07) interest (including
any Additional Interest) on the Securities having a principal amount equal to
the aggregate liquidation preference of the Preferred Securities of the
corresponding series held by such Holder.

            SECTION 5.09. Restoration of Rights and Remedies. If the Trustee or
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case the Company, the Trustee and the Holders shall, subject
to any determination in such proceeding, be restored severally and respectively
to their former positions hereunder, and thereafter all rights and remedies of
the Trustee and the Holders shall continue as though no such proceeding had been
instituted.

            SECTION 5.10. Rights and Remedies Cumulative. Except as otherwise
provided in the last paragraph of Section 3.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

            SECTION 5.11. Delay or Omission Not Waiver. Except as otherwise
provided in the last paragraph of Section 3.06, no delay or omission of the
Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.

            Every right and remedy given by this Article or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Holders, as the case may be.

            SECTION 5.12. Control by Holders. The Holders of a majority in
principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee, with respect to the Securities of such series, provided that:

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

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

                                       37

<PAGE>

                        (3) subject to the provisions of Section 6.01, the
      Trustee shall have the right to decline to follow such direction if the
      Trustee in good faith shall, by a Responsible Officer or Officers of the
      Trustee, determine that the proceeding so directed would be unjustly
      prejudicial to the Holders not joining in any such direction or would
      involve the Trustee in personal liability.

            Upon receipt by the Trustee of any written notice directing the
time, method or place of conducting any such proceeding or exercising any such
trust or power, with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless the Holders of a majority in principal amount of the
Outstanding Securities of such series shall have joined in such notice prior to
the day which is 90 days after such record date, such notice shall automatically
and without further action by any Holder be canceled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new notice identical to a
notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 5.12.

            SECTION 5.13. Waiver of Past Defaults. The Holders of not less than
a majority in principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a
default:

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

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

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

            SECTION 5.14. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall
not apply to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group

                                       38

<PAGE>

of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on any Security on or after the
respective Stated Maturities expressed in such Security.

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

                                   ARTICLE VI
                                   THE TRUSTEE

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

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

                        (2) in the absence of bad faith on its part, the Trustee
      may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon certificates or
      opinions furnished to the Trustee and conforming to the requirements of
      this Indenture; but in the case of any such certificates or opinions which
      by any 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) In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

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

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

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

                                       39

<PAGE>

                        (3) the Trustee shall not be liable with respect to any
      action taken or omitted to be taken by it in good faith in accordance with
      the direction of Holders pursuant to Section 5.12 relating to the time,
      method and place of conducting any proceeding for any remedy available to
      the Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series.

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

                  (e) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

            SECTION 6.02. Notice of Defaults. Within 90 days after actual
knowledge by a Responsible Officer of the Trustee of the occurrence of any
default hereunder with respect to the Securities of any series, the Trustee
shall transmit by mail to all Holders of Securities of such series, as their
names and addresses appear in the Securities Register, notice of such default
hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest (including any Additional
Interest) on any Security of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of Securities of such series; and provided, further,
that, in the case of any default of the character specified in Section 5.01(3),
no such notice to Holders of Securities of such series shall be given until at
least 30 days after the occurrence thereof. For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.

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

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

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

                  (c) whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any

                                       40

<PAGE>

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

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

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

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
indenture, Security or other paper or document, but the Trustee in its
discretion may make such inquiry or investigation into such facts or matters as
it may see fit, and, if the Trustee shall determine to make such inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney; and

                  (g) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by it
hereunder.

                  (h) the Trustee shall not be 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;

                  (i) 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

                  (j) 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 6.04. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of the Securities or the proceeds thereof.

                                       41

<PAGE>

            SECTION 6.05. May Hold Securities. The Trustee, any Paying Agent,
Securities Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 6.08 and 6.13, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Paying Agent, Securities Registrar or such
other agent.

            SECTION 6.06. Money Held in Trust. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed with the Company.

            SECTION 6.07. Compensation and Reimbursement. The Company agrees

                        (1) to pay to the Trustee from time to time reasonable
      compensation for all services rendered by it hereunder in such amounts as
      the Company and the Trustee shall agree from time to time (which
      compensation shall not be limited by any provision of law in regard to the
      compensation of a trustee of an express trust);

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

                        (3) to indemnify the Trustee and its officers, directors
      and employees for, and to hold each harmless against, any loss, liability,
      claim, damage or expense (including the reasonable compensation and the
      expenses and disbursements of its agents and counsel) incurred without
      negligence or bad faith, arising out of or in connection with the
      acceptance or administration of this trust or the performance of its
      duties hereunder, including the 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. This indemnification
      shall survive the termination of this Agreement and resignation or removal
      of the Trustee.

            To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee. Such lien
shall survive the satisfaction and discharge of this Indenture.

            When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 5.01(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Reform Act of 1978 or a successor statute.

            SECTION 6.08. Disqualification; Conflicting Interests. The Trustee
for the Securities of any series issued hereunder shall be subject to the
provisions of Section 3.10(b) of the Trust Indenture Act. Nothing herein shall
prevent the Trustee from filing with the Commission

                                       42

<PAGE>

the application referred to in the second to last paragraph of Section 3.10(b)
of the Trust Indenture Act.

            SECTION 6.09. Corporate Trustee Required; Eligibility. There shall
at all times be a Trustee hereunder which shall be

                  (a) a corporation organized and doing business under the laws
of the United States of America or of any State, Territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by Federal, State, Territorial or District
of Columbia authority, or

                  (b) a corporation or other Person organized and doing business
under the laws of a foreign government that is permitted to act as Trustee
pursuant to a rule, regulation or order of the Commission, authorized under such
laws to exercise corporate trust powers, and subject to supervision or
examination by authority of such foreign government or a political subdivision
thereof substantially equivalent to supervision or examination applicable to
United States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purpose of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

            SECTION 6.10. Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee under
Section 6.11.

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

                  (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company. The Trustee may petition at the expense of the Company any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

                                       43
<PAGE>

                  (d) If at any time:

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

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

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

then, in any such case, (i) the Company by Board Resolution may remove the
Trustee, or (ii) subject to Section 5.14, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause with respect to the Securities of one or more series, the Company, by
a Board Resolution, shall promptly appoint a successor Trustee with respect to
the Securities of that or those series. 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, become the successor Trustee with respect to the Securities
of such series and 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 hereinafter provided, any Holder who has been a bona fide Holder of a
Security for at least six months may, subject to Section 514, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-class mail, postage prepaid, to
the Holders of Securities of such series as their names and addresses appear in
the Securities Register. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

            SECTION 6.11. Acceptance of Appointment by Successor.

                  (a) In case of the appointment hereunder of a successor
Trustee with respect to all Securities, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment,

                                       44
<PAGE>

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

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

            SECTION 6.12. Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such

                                       45
<PAGE>

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, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

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

            SECTION 6.14. Appointment of Authenticating Agent. The Trustee may
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 and upon
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. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, or of any State, Territory or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

            An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the

                                       46
<PAGE>

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 may appoint a
successor Authenticating Agent which shall be acceptable to the Company and
shall give notice of such appointment in the manner provided in Section 1.06 to
all Holders of Securities of the series with respect to which such
Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provision of this Section.

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

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

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

                                              THE BANK OF NEW YORK TRUST

such list is furnished, excluding from any such list names and addresses
received by the Trustee in its capacity as Securities Registrar.

<PAGE>

            SECTION 7.02. Company Preservation of Information, Communications to
Holders.

                  (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders contained in the most

and addresses of Holders received by the Trustee in its capacity as Securities
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished.

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

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

            SECTION 7.03. Reports by Trustee.

                  (a) The Trustee shall transmit to Holders such reports
concerning the Trustee and its actions under this Indenture as may be required
pursuant to the Trust Indenture Act, at the times and in the manner provided
pursuant thereto.

                  (b) Reports so required to be transmitted at stated intervals
of not more than 12 months shall be transmitted no later than July 15 in each
calendar year, commencing with the first July 15 after the first issuance of
Securities under this Indenture.

                  (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange upon
which the Securities are listed and also with the Commission. The Company will
notify the Trustee whenever the Securities are listed on any stock exchange.

            SECTION 7.04. Reports by Company. The Company shall

      Securities Exchange Act of 1934 shall be filed with the Trustee within 15

      Notwithstanding that the Company may not be required to remain subject to
      the reporting requirements of Section 13 or 15(d) of the Securities
      Exchange Act of 1934, the Company shall file with the Trustee and 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 Exchange

                        (4) Delivery of such reports, information and documents
      to the Trustee is for informational purposes only and the Trustee's

      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).

                                  ARTICLE VIII
              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

            SECTION 8.01. Company May Consolidate, Etc., Only on Certain Terms.
The Company shall not consolidate with or merge into any other corporation or
convey, transfer or lease its properties and assets substantially as an entirety
to any Person, and no Person shall consolidate with or merge into the Company or
convey, transfer or lease its properties and assets substantially as an entirety
to the Company, unless:

                        (1) in case the Company shall consolidate with or merge
      into another corporation or convey, transfer or lease its properties and
      assets substantially as an entirety to any Person, the corporation formed
      by such consolidation or into which the Company is merged or the Person
      which acquires by conveyance or transfer, or which leases, the properties
      and assets of the Company substantially as an entirety shall be a
      corporation organized and existing under the laws of the United States of
      America or any State or the District of Columbia, and shall expressly
      assume, by an indenture supplemental hereto, executed and delivered to the
      Trustee, in form satisfactory to the Trustee, the due and punctual payment
      of the principal of (and premium, if any) and interest (including any
      Additional Interest) on all the Securities and the performance of every
      covenant of this Indenture on the part of the Company to be performed or
      observed;

                        (2) immediately after giving effect to such transaction,
      no Event of Default, and no event which, after notice or lapse of time, or

<PAGE>

                        (3) in the case of the Securities of a series issued to
      a AmerUs Trust, such consolidation, merger, conveyance, transfer or lease
      is permitted under the related Trust Agreement and AmerUs Guarantee and
      does not give rise to any breach or violation of the related Trust
      Agreement or AmerUs Guarantee; and

                        (4) the Company has delivered to the Trustee an
      Officers' Certificate and an Opinion of Counsel each stating that such
      consolidation, merger, conveyance, transfer or lease and any such
      supplemental indenture complies with this Article and that all conditions
      precedent herein provided for relating to such transaction have been
      complied with; and the Trustee, subject to Section 6.01, may rely upon
      such Officers' Certificate and opinion of Counsel as conclusive evidence
      that such transaction complies with this Section 8.01.

            SECTION 8.02. Successor Corporation Substituted. Upon any
consolidation or merger by the Company with or into any other corporation, or
any conveyance, transfer or lease by the Company of its properties and assets
substantially as an entirety to any Person in accordance with Section 8.01, the
successor corporation formed by such consolidation or into which the Company is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
under this Indenture with the same effect as if such successor corporation had
been named as the Company herein; and in the event of any such conveyance,
transfer or lease the Company shall be discharged from all obligations and
covenants under the Indenture and the Securities and may be dissolved and
liquidated.

            Such successor corporation may cause to be signed, and may issue
either in its own name or in the name of the Company, any or all of the
Securities issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Securities which previously shall have been signed and
delivered by the officers of the Company to the Trustee for authentication
pursuant to such provisions and any Securities which such successor corporation
thereafter shall cause to be signed and delivered to the Trustee on its behalf
for the purpose pursuant to such provisions. All the Securities so issued shall
in all respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Securities had been issued at the date of the
execution hereof.

            In case of any such consolidation, merger, sale, conveyance or
lease, such changes in phraseology and form may be made in the Securities
thereafter to be issued as may be appropriate.

                             SUPPLEMENTAL INDENTURES

            SECTION 9.01. Supplemental Indentures Without Consent of Holders.
Without the consent of any Holders, the Company, when authorized by a Board
Resolution, and the Trustee,

                                       50
<PAGE>

at any time and from time to time, may enter into one or more indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the
following purposes:

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

                        (2) to convey, transfer, assign, mortgage or pledge any
      property to or with the Trustee or to surrender any right or power herein
      conferred upon the Company; or

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

                        (4) 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 of 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

                        (5) to add any additional Events of Default; or

                        (6) 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

                        (7) to cure any ambiguity, to correct or supplement any
      provision herein which may be inconsistent with any other provision
      herein, or to make any other provisions with respect to matters or
      questions arising under this Indenture, provided that such action pursuant
      to this clause (7) shall not materially adversely affect the interest of
      the Holders of Securities of any series or, in the case of the Securities
      of a series issued to an AmerUs Trust and for so long as any of the
      corresponding series of Preferred Securities shall remain outstanding, the
      holders of such Preferred Securities; or

                        (8) to evidence and provide for the acceptance of
      appointment hereunder by a successor Trustee with respect to the
      Securities of one or more series and to add to or change any of the
      provisions of this Indenture as shall be necessary to provide for or
      facilitate the administration of the trusts hereunder by more than one
      Trustee, pursuant to the requirements of Section 6.11(b); or

                        (9) to comply with the requirements of the Commission in
      order to effect or maintain the qualification of this Indenture under the
      Trust Indenture Act.

            SECTION 9.02. Supplemental Indentures with Consent of Holders. With
the consent of the Holders of not less than a majority in principal amount of
the Outstanding Securities of each series affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company, when authorized by a Board Resolution, and the Trustee

                                       51
<PAGE>

may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

                        (1) except to the extent permitted by Section 3.11 or as
      otherwise specified as contemplated by Section 3.01 with respect to the
      extension of the interest payment period of the Securities of any series,
      change the Stated Maturity of the principal of, or any installment of
      interest (including any Additional Interest) on, any Security, or reduce
      the principal amount thereof or the rate of interest thereon or reduce any
      premium payable upon the redemption thereof, or reduce the amount of
      principal of an Original Issue Discount Security that would be due and
      payable upon a declaration of acceleration of the Maturity thereof
      pursuant to Section 5.02, or change the place of payment where, or the
      coin or currency in which, any Security or interest thereon is payable, or
      impair the right to institute suit for the enforcement of any such payment
      on or after the Stated Maturity thereof (or, in the case of redemption, on
      or after the date fixed for redemption thereof), or

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

                        (3) modify any of the provisions of this Section,
      Section 5.13 or Section 10.06, except to increase any such percentage or
      to provide that certain other provisions of this Indenture cannot be
      modified or waived without the consent of the Holder of each Security
      affected thereby; or

                        (4) modify the provisions in Article Thirteen of this
      Indenture with respect to the subordination of Outstanding Securities of
      any series in a manner adverse to the Holders thereof;

provided that, in the case of the Securities of a series issued to an AmerUs
Trust, so long as any of the corresponding series of Preferred Securities
remains outstanding, no such amendment shall be made that adversely affects the
holders of such Preferred Securities, and no termination of this Indenture shall
occur, and no waiver of any Event of Default or compliance with any covenant
under this Indenture shall be effective, without the prior consent of the
holders of at least a majority of the aggregate liquidation preference of such
Preferred Securities then outstanding unless and until the principal (and
premium, if any) of the Securities of such series and all accrued and unpaid
interest (including any Additional Interest) thereon have been paid in full; and
provided further that in the case of the Securities of a series issued to an
AmerUs Trust, so long as any of the corresponding series of Preferred Securities
remain outstanding, no amendment shall be made to Section 5.08 of this Indenture
without the prior consent of the holders of each Preferred Security then
outstanding unless and until the principal (and premium, if any) of

                                       52
<PAGE>
the Securities of such series and all accrued and (subject to Section 3.07)
unpaid interest (including any Additional Interest) thereon have been paid in
full.

            A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit 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 shall not be necessary for any Act of Holders under this Section
to approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

            SECTION 9.03. Execution of Supplemental Indentures. In executing or
accepting the additional trusts created by any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be provided with, and (subject to Section 6.01)
shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture, and that all conditions precedent
have been complied with. The Trustee may, but shall not be obligated to, enter
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

            SECTION 9.04. Effect of Supplemental Indentures. Upon the execution
of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder shall be bound
thereby.

            SECTION 9.05. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

            SECTION 9.06. Reference in Securities to Supplemental Indentures.
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Securities
of any series so modified as to conform, in the opinion of the Trustee and the
Board of Directors, 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 of such series.

                                   ARTICLE X
                                   COVENANTS

            SECTION 10.01. Payment of Principal, Premium and Interest. The
Company covenants and agrees for the benefit of each series of securities that
it will duly and punctually pay the principal of (and premium, if any) and
interest on the Securities of that series in accordance with the terms of such
Securities and this Indenture.

                                       53
<PAGE>

            SECTION 10.02. Maintenance of Office or Agency. The Company will
maintain in each Place of Payment for any series, an office or agency where
Securities of that series may be presented or surrendered for payment and an
office or agency where Securities may be surrendered for transfer or exchange
and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The Company initially appoints the
Trustee, acting through its Corporate Trust Office, as its agent for said
purposes. The Company will give prompt written notice to the Trustee of any
change in the location of any such office or agency. If at any time the Company
shall fail to maintain such 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.

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

            SECTION 10.03. Money for Security Payments to be Held in Trust. If
the Company shall at any time act as its own Paying Agent with respect to any
series of Securities, it will, on or before each due date of the principal of
(and premium, if any) or interest on any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and will promptly notify the Trustee of its failure so to
act.

            Whenever the Company shall have one or more Paying Agents, it will,
prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal and premium (if any) or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its failure so to act.

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

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

                                       54
<PAGE>

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

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

                        (4) comply with the provisions of the Trust Indenture
      Act applicable to it as a Paying Agent.

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

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of (and premium,
if any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request to the Company,
or (if then held by the Company) shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be
discharged from such trust; and the Holder of such Security 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 Borough of
Manhattan, The City of New York, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid the Company.

            SECTION 10.04. Payment of Taxes and Other Claims. The Company will
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Restricted Subsidiary or upon the income,
profits or property of the Company or any Restricted Subsidiary, and (2) all
lawful claims for labor, materials and supplies which, if unpaid, might by law
become a lien upon the property of the Company or any Restricted Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.

                                       55
<PAGE>

            SECTION 10.05. Statement as to Compliance. The Company shall deliver
to the Trustee, within 120 days after the end of each calendar year of the
Company ending after the date hereof, an Officers' Certificate covering the
preceding fiscal year, stating whether or not to the knowledge of the signers
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 purpose of this Section 10.05, compliance shall be determined without regard
to any grace period or requirement of notice provided pursuant to the terms of
this Indenture.

            SECTION 10.06. Waiver of Certain Covenants. The Company may omit in
any particular instance to comply with any covenant or condition set forth in
Section 10.04 or as specified as contemplated by Section 3.01 with respect to
the Securities of any series, if before or after the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company in respect of any such covenant
or condition shall remain in full force and effect.

            SECTION 10.07. Additional Sums. In the case of the Securities of a
series issued to an AmerUs Trust, except as otherwise specified as contemplated
by Section 3.01, in the event that (i) an AmerUs Trust is the Holder of all of
the Outstanding Securities of such series, (ii) a Tax Event in respect of such
AmerUs Trust shall have occurred and be continuing and (iii) the Company shall
not have (i) redeemed the Securities of such series pursuant to Section 11.07(b)
or (ii) terminated such AmerUs Trust pursuant to section 9.02(b) of the related
Trust Agreement, the Company shall pay to such AmerUs Trust (and its permitted
successors or assigns under the related Trust Agreement) for so long as such
AmerUs Trust (or its permitted successor or assignee) is the registered holder
of any Securities of such series, such additional amounts as may be necessary in
order that the amount of distributions (including any Additional Amounts (as
defined in the Trust Agreement)) then due and payable by such AmerUs Trust on
the related Preferred Securities and Common Securities that at any time remain
outstanding in accordance with the terms thereof shall not be reduced as a
result of any Additional Taxes (the "Additional Sums"); provided that, if this
Indenture has not been qualified under the Trust Indenture Act, the Company
shall be required to pay such Additional Sums until this Indenture is so
qualified. Whenever in this Indenture or the Securities there is a reference in
any context to the payment of principal of or interest on the Securities, such
mention shall be deemed to include mention of the payments of the Additional
Sums provided for in this paragraph to the extent that, in such context,
Additional Sums are, were or would be payable in respect thereof pursuant to the
provisions of this paragraph and express mention of the payment of Additional
Sums (if applicable) in any provisions hereof shall not be construed as
excluding Additional Sums in those provisions hereof where such express mention
is not made, provided, however, that the extension of an interest payment period
pursuant to Section 3.11 of the Securities shall not extend the payment of any
Additional Sums that may be due and payable during such interest payment period.

            SECTION 10.08. Additional Covenants. The Company covenants and
agrees with each Holder of Securities of a series issued to an AmerUs Trust that
it will not, and it will not

                                       56
<PAGE>

permit any Subsidiary of the Company to, (a) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any shares of the Company's capital stock, or (b) make any
payment of principal, interest or premium, if any, on or repay, repurchase or
redeem any debt securities that rank pari passu with or junior to the Securities
of such series or make any guarantee payments with respect to the foregoing
(other than (a) dividends or distributions in common stock of the Company, (b)
redemptions or purchases of any rights pursuant to the Company's rights plan, if
any, or any successor to such rights plan, and the declaration of a dividend of
such rights in the future, and (c) payments under any AmerUs Guarantee) if at
such time (i) there shall have occurred any event of which the Company has
actual knowledge that (a) with the giving of notice or the lapse of time or
both, would constitute an Event of Default hereunder and (b) in respect of which
the Company shall not have taken reasonable steps to cure, (ii) the Company
shall be in default with respect to its payment of any obligations under the
related AmerUs Guarantee or (iii) the Company shall have given notice of its
selection of an Extension Period as provided herein and shall not have rescinded
such notice, or such period, or any extension thereof, shall be continuing.

            The Company also covenants with each Holder of Securities of a
series issued to an AmerUs Trust (i) to maintain directly or indirectly 100%
ownership of the Common Securities of such AmerUs Trust; provided, however, that
any permitted successor of the Company hereunder may succeed to the Company's
ownership of such Common Securities, (ii) not to voluntarily terminate, wind-up
or liquidate such AmerUs Trust, except (a) in connection with a distribution of
the Securities of such series to the holders of Preferred Securities in
liquidation of such AmerUs Trust or (b) in connection with certain mergers or
consolidations permitted by the related Trust Agreement and (iii) to use its
reasonable efforts, consistent with the terms and provisions of such Trust
Agreement, to cause such AmerUs Trust to remain a statutory trust and not to be
classified as an association taxable as a corporation for United States federal
income tax purposes.

            SECTION 10.09. 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 XI
                            REDEMPTION OF SECURITIES

            SECTION 11.01. Applicability of This Article. Redemption of
Securities (whether by operation of a sinking fund or otherwise) as permitted or
required by any form of Security issued pursuant to this Indenture shall be made
in accordance with such form of Security and this Article; provided, however,
that if any provision of any such form of Security shall conflict with any
provision of this Article, the provision of such form of Security shall govern.
Except as otherwise set forth in the form of Security for such series, each
Security shall be subject to partial redemption only in the amount of $25 or, in
the case of the Securities of a series issued to a AmerUs Trust, $25, or
integral multiples thereof.

                                       57
<PAGE>

            SECTION 11.02. Election to Redeem; Notice to Trustee. The election
of the Company to redeem any Securities 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 of the Securities of any particular series and having the same
terms, the Company shall, not less than 30 nor more than 60 days prior to the
date fixed for redemption (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such date and of the principal amount of
Securities of that series to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities, the Company shall furnish the Trustee
with an Officers' Certificate and an Opinion of Counsel evidencing compliance
with such restriction.

            SECTION 11.03. Selection of Securities to be Redeemed. If less than
all the Securities of a particular series and having the same terms are to be
redeemed, the Trustee shall select, not more than 60 days prior to the date
fixed for redemption, in such manner as in its sole discretion it shall deem
appropriate and fair, the Securities or portions thereof of such series to be
redeemed. The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and the principal amount thereof to
be redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is 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.

            SECTION 11.04. Notice of Redemption. Notice of redemption shall be
given by first-class mail, postage prepaid, mailed not later than the thirtieth
day, and not earlier than the sixtieth day, prior to the date fixed for
redemption, to each Holder of Securities to be redeemed, at the address of such
Holder as it appears in the Securities Register.

            With respect to Securities of each series to be redeemed, each
notice of redemption shall state:

                  (a) the date fixed for redemption for Securities of such
series;

                  (b) the redemption price at which Securities of such series
are to be redeemed;

                  (c) if less than all Outstanding Securities of such particular
series and having the same terms are to be redeemed, the identification (and, in
the case of partial redemption, the respective principal amounts) of the
particular Securities to be redeemed;

                  (d) that on the date fixed for redemption, the redemption
price at which such Securities are to be redeemed will become due and payable
upon each such Security or portion thereof, and that interest thereon, if any,
shall cease to accrue on and after said date;

                  (e) the place or places where such Securities are to be
surrendered for payment of the redemption price at which such Securities are to
be redeemed; and

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

                                       58
<PAGE>

            Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company. The notice if mailed in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives such notice. In any case, a failure to
give such notice by mail or any defect in the notice to the Holder of any
Security designated for redemption as a whole or in part shall not affect the
validity of the proceedings for the redemption of any other Security.

            SECTION 11.05. Deposit of Redemption Price. Prior to the redemption
date specified in the notice of redemption given as provided in Section 11.04,
the Company will deposit with the Trustee or with one or more paying agents an
amount of money sufficient to redeem on the redemption date all the Securities
so called for redemption at the applicable redemption price.

            SECTION 11.06. Payment of Securities Called for Redemption. If any
notice of redemption has been given as provided in Section 11.04, the Securities
or portion of Securities with respect to which such notice has been given shall
become due and payable on the date and at the place or places stated in such
notice at the applicable redemption price. On presentation and surrender of such
Securities at a place of payment in said notice specified, the said securities
or the specified portions thereof shall be paid and redeemed by the Company at
the applicable redemption price.

            Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Company, a new Security or Securities of the same
series, of authorized denominations, in aggregate principal amount equal to the
unredeemed portion of the Security so presented and having the same Original
Issue Date, Stated Maturity and terms. If a Global Security is so surrendered,
such new Security will also be a new Global Security.

            SECTION 11.07. Company's Right of Redemption. (a) Unless otherwise
specified as contemplated by Section 3.01 with respect to the Securities of a
particular series and notwithstanding any additional redemption rights that may
be so specified, the Company may, at its option, redeem the Securities of any
series after their date of issuance in whole or in part at any time and from
time to time, subject to the provisions of this clause (a) and the other
provisions of this Article Eleven. Unless otherwise specified as contemplated by
Section 301 with respect to the Securities of a particular series, the
redemption price for any Security so redeemed pursuant to this clause (a) shall
equal any accrued and unpaid interest, including any Additional Interest, to the
date fixed for redemption, plus the greater of (a) the principal amount thereof
and (b) an amount equal to (i) in respect of the Securities of any series
bearing interest at a fixed rate, the Discounted Remaining Fixed Amount Payments
or (ii) in respect of the Securities of any series bearing interest determined
by reference to a floating rate, the Discounted Swap Equivalent Payments. The
Company shall not redeem the Securities in part unless all accrued and unpaid
interest (including any Additional Interest) has been paid in full on all
Securities Outstanding for all interest periods terminating on or prior to the
date fixed for redemption. For purposes of this clause (a), the following terms
shall have the meanings set forth below:

            "Discounted Remaining Fixed Amount Payments" means, in respect of a
Security of any series bearing interest at a fixed rate, an amount equal to the
sum of the Current Values of

                                       59
<PAGE>

the amounts of interest and principal that would have been payable by the
Company pursuant to the terms of such Security on each Interest Payment Date
after the date fixed for redemption pursuant to this Section 11.07 and at the
Stated Maturity of the final payment of principal thereof (taking into account
any required sinking fund payments but otherwise assuming that the Company had
not redeemed such Security prior to such Stated Maturity).

            "Current Value" means, in respect of any amount, the present value
of that amount on the date fixed for redemption pursuant to this Section 11.07
after discounting that amount on a basis corresponding to the interest period of
the Securities to be redeemed from the originally scheduled date for payment on
the basis of the Treasury Rate, all computed in accordance with generally
accepted financial practice.

            "Treasury Rate" means a per annum rate (expressed as a decimal and,
in the case of United States Treasury bills, converted to a per annum yield)
determined on the date fixed for redemption pursuant to this Section 11.07 to be
the per annum rate equal to the semiannual bond equivalent yield to maturity
adjusted, in the case of Securities having monthly or quarterly Interest Payment
Dates, to reflect monthly or quarterly compounding in accordance with generally
accepted financial practice for United States Treasury securities maturing at
the Stated Maturity of the final payment of principal of any series of
Securities redeemed pursuant to this Section 1107, as determined (i) by
reference to the weekly average yield to maturity for United States Treasury
securities maturing on such Stated Maturity as reported in the most recent
Statistical Release H.15(519) of the Board of Governors of the Federal Reserve,
or (ii) if no such weekly average yield is so reported, by interpolation between
the most recent weekly average yields to maturity for two series of United
States Treasury securities, (a) one maturing as close as possible to, but
earlier than, such Stated Maturity and (b) the other maturing as close as
possible to, but later than, such Stated Maturity, in each case as published in
the most recent Statistical Release H.15(519) of the Board of Governors of the
Federal Reserve.

            "Discounted Swap Equivalent Payments" means, in respect of a
Security of any series bearing interest determined by reference to a floating
rate, an amount equal to the sum of (i) the Current Value of the amount of
principal that would have been payable by the Company pursuant to the terms of
such Security at the Stated Maturity of the final payment of the principal
thereof (taking into effect any required sinking fund payments but otherwise
assuming that the Company had not redeemed such Security prior to such Stated
Maturity) and (ii) the sum of the Current Values of the fixed rate payments that
Reference Market-Makers would require to be paid by an assumed fixed rate payer
having the same credit standing as the Company against floating rate payments to
be made by such Reference Market-Makers equal to the interest payments on the
Security being redeemed (taking into effect any required sinking fund payments
but otherwise assuming the Company had not redeemed such Security prior to such
Stated Maturity) under an interest rate swap agreement documented under standard
forms of the International Swap Dealers Association, Inc., and having a notional
principal amount equal to the principal amount of such Security, a termination
date set at the Stated Maturity of such Security and payment dates for both
fixed and floating rate payers set at each Interest Payment Date of such
Security. The Trustee (or its agent) will request each Reference Market-Maker to
provide its quotation of such fixed rate payments to the extent practicable as
of the same time (without regard to different time zones) on a date that is no
more than five Business Days prior to the date on which the notice of redemption
required by Section 11.04 is first mailed to the Holders of the Securities

                                       60
<PAGE>

being redeemed. If more than three such quotations are provided, the fixed rate
payments will be the arithmetic mean of the dollar equivalent of such quotations
without regard to the quotations having the highest and lowest values. If
exactly three such quotations are provided, the fixed rate payments will be the
quotation remaining after disregarding the quotations having the highest and
lowest values.

            "Reference Market-Makers" means four leading dealers in the market
for interest rate swaps selected by the Trustee (or its agent) in good faith
from among dealers of the highest credit standing which satisfy all the criteria
that the Trustee (or its agent) applies generally at the time in deciding
whether to offer or to make an extension of credit or, if quotations from four
such leading dealers are not reasonably obtainable, three such leading dealers.

                  (b) In the case of the Securities of a series issued to an
AmerUs Trust, except as otherwise specified as contemplated by Section 301, if a
Special Event in respect of such AmerUs Trust shall occur and be continuing, the
Company may, at its option, redeem the Securities of such series, in whole but
not in part, subject to the provisions of this clause (b) and the other
provisions of this Article Eleven. The redemption price for any Security so
redeemed pursuant to this clause (b) shall be equal to 100% of the principal
amount of such Securities then Outstanding plus accrued and unpaid interest,
including any Additional Interest, to the date fixed for redemption.

            Notwithstanding any other provision of this Article 11, installments
of accrued and unpaid interest whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holders of the series of Securities to be
redeemed, or one or more Predecessor Securities, registered as such at the close
of business on the relevant Regular Record Dates according to their terms and
the provisions of Section 3.07.

                                  ARTICLE XII
                           SUBORDINATION OF SECURITIES

            SECTION 12.01. Securities Subordinate to Senior Debt. The Company
covenants and agrees, and each Holder of a Security, by its acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this Article, the payment of the principal of (and premium, if any)
and interest (including any Additional Interest) on each and all of the
Securities are hereby expressly made subordinate and subject in right of payment
to the prior payment in full of all amounts then due and payable in respect of
all Senior Debt.

            SECTION 12.02. Payment Over of Proceeds Upon Dissolution, Etc. In
case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company (each such event, if any, herein sometimes
referred to as a "Proceeding"), then the holders of Senior Debt shall be
entitled to receive payment in full of principal of (and premium, if any) and
interest, if any, on such Senior Debt, or provision shall be made for such
payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, before the Holders of the Securities are entitled to
receive or retain any payment or distribution of any kind or character, whether
in cash, property or securities (including any payment or distribution which may
be payable or deliverable by reason of the payment of any other Debt of the
Company (including any

                                       61
<PAGE>

series of the Securities) subordinated to the payment of the Securities, such
payment or distribution being hereinafter referred to as a "Junior Subordinated
Payment"), on account of principal of (or premium, if any) or interest
(including any Additional Interest) on the Securities or on account of the
purchase or other acquisition of Securities by the Company or any Subsidiary and
to that end the holders of Senior Debt shall be entitled to receive, for
application to the payment thereof, any payment or distribution of any kind of
character, whether in cash, property or securities, including any Junior
Subordinated Payment, which may be payable or deliverable in respect of the
Securities in any such Proceeding.

            In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any Junior Subordinated
Payment, before all Senior Debt is paid in full or payment thereof is provided
for in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, and if such fact shall, at or prior to the time of such
payment or distribution, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment or distribution shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

            For purposes of this Article only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which securities are subordinated in
right of payment to all then outstanding Senior Debt to substantially the same
extent as the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a Proceeding for the purposes of this Section if the Person formed by
such consolidation or into which the Company is merged or the Person which
acquires by sale such properties and assets as an entirety, as the case may be,
shall, as a part of such consolidation, merger, or sale comply with the
conditions set forth in Article Eight.

            SECTION 12.03. Prior Payment to Senior Debt Upon Acceleration of
Securities. In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Senior Debt
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts due on or in respect of such
Senior Debt (including any amounts due upon acceleration), or provision shall be
made for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Debt, before the Holders of the Securities
are entitled to receive any payment or distribution of any kind or character,
whether in cash, properties or securities (including any Junior Subordinated
Payment) by the Company on account of the principal of (or premium, if any) or
interest (including any Additional Interest) on the Securities or on account of
the purchase or other

                                       62
<PAGE>

acquisition of Securities by the Company or any Subsidiary; provided, however,
that nothing in this Section shall prevent the satisfaction of any sinking fund
payment in accordance with this Indenture or as otherwise specified as
contemplated by Section 3.01 for the Securities of any series by delivering and
crediting as contemplated by Section 3.01 for the Securities of any series
Securities which have been acquired (upon redemption or otherwise) prior to such
declaration of acceleration.

            In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

            The provisions of this Section shall not apply to any payment with
respect to which Section 12.02 would be applicable.

            SECTION 12.04. No Payment When Senior Debt in Default. (a) In the
event and during the continuation of any default in the payment of principal of
(or premium, if any) or interest on any Senior Debt, or in the event that any
event of default with respect to any Senior Debt shall have occurred and be
continuing and shall have resulted in such Senior Debt becoming or being
declared due and payable prior to the date on which it would otherwise have
become due and payable, unless and until such event of default shall have been
cured or waived or shall have ceased to exist and such acceleration shall have
been rescinded or annulled, or (b) in the event any judicial proceeding shall be
pending with respect to any such default in payment or such event or default,
then no payment or distribution of any kind or character, whether in cash,
properties or securities (including any Junior Subordinated Payment) shall be
made by the Company on account of principal of (or premium, if any) or interest
(including any Additional Interest), if any, on the Securities or on account of
the purchase or other acquisition of Securities by the Company or any
Subsidiary; provided, however, that nothing in this Section shall prevent the
satisfaction of any sinking fund payment in accordance with this Indenture or as
otherwise specified as contemplated by Section 3.01 for the Securities of any
series by delivering and crediting pursuant to Section 12.02 or as otherwise
specified as contemplated by Section 3.01 for the Securities of any series
Securities which have been acquired (upon redemption or otherwise) prior to such
default in payment or event of default.

            In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

            The provisions of this Section shall not apply to any payment with
respect to which Section 12.02 would be applicable.

            SECTION 12.05. Payment Permitted If No Default. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Securities shall
prevent (a) the Company, at any time except during the pendency of any
Proceeding referred to in Section 12.02 or under the

                                       63
<PAGE>

conditions described in Sections 12.03 and 12.04, from making payments at any
time of principal of (and premium, if any) or interest on the Securities, or (b)
the application by the Trustee of any money or Government Obligations deposited
with it hereunder to the payment of or on account of the principal of (and
premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

            SECTION 12.06. Subrogation to Rights of Holders of Senior
Indebtedness. Subject to the payment in full of all Senior Debt, or the
provision for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Debt, the Holders of the Securities shall
be subrogated to the extent of the payments or distributions made to the holders
of such Senior Debt pursuant to the provisions of this Article (equally and
ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to Senior Debt of the Company to substantially the same
extent as the Securities are subordinated to the Senior Debt and is entitled to
like rights of subrogation by reason of any payments or distributions made to
holders of such Senior Debt) to the rights of the holders of such Senior Debt to
receive payments and distributions of cash, property and securities applicable
to the Senior Debt until the principal of (and premium, if any) and interest on
the Securities shall be paid in full. For purposes of such subrogation or
assignment, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Debt by Holders of the Securities or the Trustee, shall, as among the
Company, its creditors other than holders of Senior Debt, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Debt.

            SECTION 12.07. Provisions Solely to Define Relative Rights. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Debt on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as between the Company and the Holders of the Securities, the
obligations of the Company, which are absolute and unconditional, to pay to the
Holders of the Securities the principal of (and premium, if any) and interest
(including any Additional Interest) on the Securities as and when the same shall
become due and payable in accordance with their terms; or (b) affect the
relative rights against the Company of the Holders of the Securities and
creditors of the Company other than their rights in relation to the holders of
Senior Debt; or (c) prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture including, without limitation, filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

            SECTION 12.08. Trustee to Effectuate Subordination. Each Holder of a
Security by his or her acceptance thereof authorizes and directs the Trustee on
his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination provided

                                       64
<PAGE>

in this Article and appoints the Trustee his or her attorney-in-fact for any and
all such purposes.

            SECTION 12.09. No Waiver of Subordination Provisions. No right of
any present or future holder of any Senior Debt to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or be otherwise charged with.

            SECTION 12.10. Notice to Trustee. The Company shall give prompt
written notice to the Trustee of any fact known to the Company which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities. Notwithstanding the provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of the Securities, unless and until the Trustee shall
have received written notice thereof from the Company or a holder of Senior Debt
or from any trustee, agent or representative therefor (whether or not the facts
contained in such notice are true); provided, however, that if the Trustee shall
not have received the notice provided for in this Section at least two Business
Days prior to the date upon which by the terms hereof any monies may become
payable for any purpose (including, without limitation, the payment of the
principal of (and premium, if any) or interest (including any Additional
Interest) on any Security), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
monies and to apply the same to the purpose for which they were received and
shall not be affected by any notice to the contrary which may be received by it
within two Business Days prior to such date.

            SECTION 12.11. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee, subject to the provisions of Article
Six, and the Holders of the Securities shall be entitled to rely upon any order
or decree entered by any court of competent jurisdiction in which such
Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee for the benefit of creditors, agent or
other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of the Senior Debt
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

            SECTION 12.12. Trustee Not Fiduciary for Holders of Senior Debt. The
Trustee, in its capacity as trustee under this Indenture, shall not be deemed to
owe any fiduciary duty to the holders of Senior Debt and shall not be liable to
any such holders if it shall in good faith mistakenly pay over or distribute to
Holders of Securities or to the Company or to any other Person ash, property or
securities to which any holders of Senior Debt shall be entitled by virtue of
this Article or otherwise.

            SECTION 12.13. Rights of Trustee as Holder of Senior Debt;
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in

                                       65
<PAGE>

this Article with respect to any Senior Debt which may at any time be held by
it, to the same extent as any other holder of Senior Debt, and nothing in this
Indenture shall deprive the Trustee of any of its rights as such holder.

            SECTION 12.14. Article Applicable to Paying Agents. In case at any
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee.

            SECTION 12.15. Certain Conversions or Exchanges Deemed Payment. For
the purposes of this Article only, (a) the issuance and delivery of junior
securities upon conversion or exchange of Securities shall not be deemed to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest (including any Additional Interest) on Securities or on
account of the purchase or other acquisition of Securities, and (b) the payment,
issuance or delivery of cash, property or securities (other than junior
securities) upon conversion or exchange of a Security shall be deemed to
constitute payment on account of the principal of such security. For the
purposes of this Section, the term "junior securities" means (i) shares of any
stock of any class of the Company and (ii) securities of the Company which are
subordinated in right of payment to all Senior Debt which may be outstanding at
the time of issuance or delivery of such securities to substantially the same
extent as, or to a greater extent than, the Securities are so subordinated as
provided in this Article.

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

                                 TRUST AGREEMENT

            This TRUST AGREEMENT, dated as of ___________, 2005, between AmerUs

(Delaware) a Delaware banking corporation as "Trustee". The Depositor and the

            1. The trust created hereby shall be known as AmerUs Capital _____,
in which name the Trustee, or the Depositor to the extent provided herein, may
conduct the business of the Trust, make and execute contracts, and sue and be
sued.

            2. The Depositor hereby assigns, transfers, conveys and sets over to
the Trustee the sum of $10. The Trustee hereby acknowledges receipt of such
amount in trust from the Depositor, which amount shall constitute the initial
trust estate. The Trustee hereby declares that it will hold the trust estate in

provisions of the Statutory Trust Act.

            3. The Depositor and the Trustee will enter into an amended and
restated Trust Agreement, satisfactory to each such party and substantially in
the form included as an exhibit to the 1933 Act Registration Statement (as
defined below), to provide for the contemplated operation of the Trust created
hereby and the issuance of the Preferred Securities and Common Securities
referred to therein. Prior to the execution and delivery of such amended and
restated Trust Agreement, the Trustee shall not have any duty or obligation
hereunder or with respect to the trust estate, and the Depositor shall take or
cause to be taken any action as may be required to obtain any licenses, consents
or approvals required by applicable law or otherwise. Notwithstanding the
foregoing, the Trustee may take all actions requested by the Depositor which the
Depositor deems necessary, convenient or incidental to effect the transactions
contemplated herein. Except as otherwise expressly required by Section 2 herein,
the Trustee shall not have any duty or obligation under or in connection with
this Trust Agreement or any document contemplated hereby, including, without
limitation, with respect to the administration of the Trust, and no implied
duties or obligations shall be inferred from or read into this Trust Agreement
against or with respect to the Trustee. The Trustee has no duty or obligation to
supervise or monitor the performance of, or compliance with this Trust
Agreement, by the Depositor or any other beneficiaries, any agents or
attorneys-in-fact of the Depositor, or any other trustee of the Trust. The
Trustee shall not be liable for the acts or omissions of the Depositor or any
other beneficiaries, any agents or attorneys-in-fact of the Depositor, or any
other trustee of the Trust nor shall the Trustee be liable for any act or
omission by it in good faith in accordance with the directions of the Depositor.
The right of the Trustee to perform any discretionary act enumerated herein
shall not be construed as a duty.

                                       1

            4. The Depositor is hereby authorized, (i) to file with the
Securities and Exchange Commission (the "Commission") and execute, in each case
on behalf of the Trust, (a) the Registration Statement on Form S-3 (the "1933
Act Registration Statement"), including any pre-effective or post-effective
amendments to such 1933 Act Registration Statement (including the prospectus and
the exhibits contained therein), relating to the registration under the
Securities Act of 1933, as amended, of the Preferred Securities of the Trust and
certain other securities and (b) a Registration Statement on Form 8-A (the "1934
Act Registration Statement") (including all pre-effective and post-effective
amendments thereto) relating to the registration of the Preferred Securities of
the Trust under Section 12(b) of the Securities Exchange Act of 1934, as
amended; (ii) to file with the New York Stock Exchange (the "Exchange") and
execute on behalf of the Trust a listing application and all other applications,
statements, certificates, agreements and other instruments as shall be necessary
or desirable to cause the Preferred Securities to be listed on the Exchange;
(iii) to file and execute on behalf of the Trust such applications, reports,
surety bonds, irrevocable consents, appointments of attorney for service of
process and other papers and documents as shall be necessary or desirable to
register the Preferred Securities under the securities or "Blue Sky" laws, and
to obtain any permits under the insurance laws of such jurisdictions as the
Depositor, on behalf of the Trust, may deem necessary or desirable and (iv) to
execute on behalf of the Trust one or more Underwriting Agreements with one or
more underwriters relating to the offering of the Preferred Securities. In the
event that any filing referred to in clauses (i), (ii) and (iii) above is
required by the rules and regulations of the Commission, the Exchange or state
securities or blue sky laws, to be executed on behalf of the Trust by a Trustee,
the Depositor and any Trustee appointed pursuant to Section 6 hereof are hereby
authorized to join in any such filing and to execute on behalf of the Trust any
and all of the foregoing. In connection with all of the foregoing, the Depositor
hereby constitutes and appoints Thomas C. Godlasky, Melinda S. Urion and James
A. Smallenberger, and each of them, as its true and lawful attorneys-in-fact and
agents, with full power of substitution and resubstitution, for the Depositor or
in the Depositor's name, place and stead, in any and all capacities, to sign any
and all amendments (including post-effective amendments) to the 1933 Act
Registration Statement and the 1934 Act Registration Statement and to file the
same, with all exhibits thereto, and other documents in connection therewith,
with the Commission, granting unto said attorneys-in-fact and agents full power
and authority to do and perform each and every act and thing requisite and
necessary to be done in connection therewith, as fully to all intents and
purposes as the Depositor might or could do in person, hereby ratifying and
confirming all that said attorneys-in-fact and agents or any of them, or their
respective substitute or substitutes, shall do or cause to be done by virtue
hereof.

            5. The Trustee is authorized to take such action or refrain from
taking such action under this Trust Agreement as it may be directed in writing
by the Depositor from time to time; provided, however, that the Trustee shall
not be required to take or refrain from taking any such action if it shall have
determined, or shall have been advised by counsel, that such performance is
likely to involve the Trustee in personal liability or is contrary to the terms
of this Trust Agreement or of any document contemplated hereby to which the
Trust or the Trustee is a party or is otherwise contrary to law. If at any time
the Trustee determines that it requires or desires guidance regarding the
application of any provision of this Trust Agreement or any other document, or
regarding compliance with any direction it received hereunder, then the Trustee
may deliver a notice to the Depositor requesting written instructions as to the
course of action desired by the Depositor, and such instructions by or on behalf
of the Depositor shall constitute full and complete authorization and protection
for actions taken and other performance by the Trustee in

                                       2
<PAGE>

reliance thereon. Until the Trustee has received such instructions after
delivering such notice, it may refrain from taking any action with respect to
the matters described in such notice.

            6. The Depositor hereby agrees to (i) reimburse the Trustee for all
reasonable expenses (including reasonable fees and expenses of counsel and other
experts), (ii) indemnify, defend and hold harmless the Trustee and the officers,
directors, employees and agents of the Trustee (collectively, including the
Trustee in its individual capacity, the "Indemnified Persons") from and against
any and all losses, damages, liabilities, claims, actions, suits, costs,
expenses, disbursements (including the reasonable fees and expenses of counsel),
taxes and penalties of any kind and nature whatsoever (collectively,
"Expenses"), to the extent that such Expenses arise out of or are imposed upon
or asserted at any time against such Indemnified Persons with respect to the
performance of this Trust Agreement, the creation, operation, administration or
termination of the Trust, or the transactions contemplated hereby; provided,
however, that the Depositor shall not be required to indemnify an Indemnified
Person for Expenses to the extent such Expenses result from the willful
misconduct, bad faith or negligence of such Indemnified Person, and (iii)
advance to each such Indemnified Person Expenses (including reasonable fees and
expenses of counsel) incurred by such Indemnified Person, in defending any
claim, demand, action, suit or proceeding prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Depositor of an
undertaking, by or on behalf of such Indemnified Person, to repay such amount if
it shall be determined that such Indemnified Person is not entitled to be
indemnified therefor under this Section 6. The obligations of the Depositor
under this Section 6 shall survive the resignation or removal of any Trustee,
shall survive the termination of this Trust Agreement, except by amendment and
restatement of this Trust Agreement, and shall survive the transfer by the
Depositor of any or all of its interest in the Trust.

            7. This Trust Agreement may be executed in one or more counterparts,
each of which shall be deemed an original but all of which together shall
constitute one and the same instrument.

            8. The number of Trustees initially shall be one (1) and thereafter
the number of Trustees shall be such number as shall be fixed from time to time
by a written instrument signed by the Depositor which may increase or decrease
the number of Trustees; provided, however, that to the extent required by the
Statutory Trust Act, one Trustee shall either be a natural person who is a
resident of the State of Delaware or, if not a natural person, an entity which
has its principal place of business in the State of Delaware and otherwise meets
the requirements of applicable Delaware law. Subject to the foregoing, the
Depositor is entitled to appoint or remove without cause any Trustee at any
time. The Trustee may resign upon thirty days' prior notice to the Depositor.

            9. This Trust Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware (without regard to conflict
of laws of principles).

         SECTION 4.2 REDEMPTION.

            (a) On each Debenture Redemption Date and on the stated maturity of

            (b) Notice of redemption shall be given by the Property Trustee by

                  (i) the Redemption Date;

                  (ii) the Redemption Price;

                  (iii) the CUSIP number;

                  (iv) if less than all the Outstanding Trust Securities are to

            (d) If the Property Trustee gives a notice of redemption in respect
of any Preferred Securities, then, by 12:00 noon, New York time, on the

as the Preferred Securities are in book-entry-only form, irrevocably deposit
with the Clearing Agency for the Preferred Securities funds sufficient to pay
the applicable Redemption Price and will give such Clearing Agency irrevocable
instructions

                                       16

and authority to pay the Redemption Price to the holders thereof. If the
Preferred Securities are no longer in book-entry-only form, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the holders thereof upon surrender of their Preferred Securities
Certificates. Notwithstanding the foregoing, Distributions payable on or prior
to the Redemption Date for any Trust Securities called for redemption shall be
payable to the Holders of such Trust Securities as they appear on the Register
for the Trust Securities on the relevant record dates for the related

payment in respect of any such delay), except that, if such Business Day falls

on such date. In the event that payment of the Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused and
not paid either by the Trust or by the Depositor pursuant to the Guarantee,
Distributions on such Trust Securities will continue to accrue, at the then
applicable rate, from the Redemption Date originally established by the Trust
for such Trust Securities to the date such Redemption Price is actually paid, in
which case the actual payment date will be the date fixed for redemption for
purposes of calculating the Redemption Price.

            (e) Payment of the Redemption Price on the Trust Securities shall be
made to the recordholders thereof as they appear on the Securities Register for
the Trust Securities on the relevant record date, which shall be one Business
Day prior to the relevant Redemption Date; provided, however, that in the event
that the Preferred Securities do not remain in book-entry-only form, the
relevant record date shall be the fifteenth day prior to the Redemption Date.

            (f) If less than all the Outstanding Trust Securities are to be
redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust
Securities to be redeemed shall be allocated on a pro rata basis (based on
Liquidation Amounts) among the Common Securities and the Preferred Securities.
The particular Preferred Securities to be redeemed shall be selected on a pro
rata basis (based upon Liquidation Amounts) not more than 60 days prior to the
Redemption Date by the Property Trustee from the Outstanding Preferred
Securities not previously called for redemption, by such method as the Property
Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to $__ or an integral multiple of $__ in
excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $___. The Property Trustee shall promptly notify the
Security Registrar in writing of the Preferred Securities selected for

redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the Liquidation Amount of Preferred Securities which has been or is to be

            (a) Payment of Distributions (including Additional Amounts, if
applicable) on, and the Redemption Price of, the Trust Securities, as
applicable, shall be made pro rata based on the Liquidation Amount of the Trust
Securities; provided, however, that if on any Distribution Date or Redemption
Date a Debenture Event of Default shall have occurred and be continuing, no
payment of any Distribution (including Additional Amounts, if applicable) on, or
Redemption Price of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid Distributions

Securities for all distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities, shall have been made or provided
for, and all funds immediately available to the Property Trustee shall first be
applied to the payment in full in cash of all Distributions (including
Additional Amounts, if applicable) on, or Redemption Price of, Preferred
Securities then due and payable.

            (b) In the case of the occurrence of any Debenture Event of Default,
the Holder of Common Securities will be deemed to have waived any right to act
with respect to any such Event of Default under this Trust Agreement until the
effect of all such Events of Default with respect to the Preferred Securities
have been cured, waived or otherwise eliminated. Until any such Event of Default
under this Trust Agreement with respect to the Preferred Securities have been so
cured, waived or otherwise eliminated, the Property Trustee shall act solely on
behalf of the Holders of the Preferred Securities and not the Holder of the
Common Securities, and only the Holders of the Preferred Securities will have
the right to direct the Property Trustee to act on their behalf.

         SECTION 5.4 REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED
SECURITIES CERTIFICATES.

            The Securities Registrar shall keep or cause to be kept, at the
office or agency maintained pursuant to Section 5.8, a Securities Register in
which, subject to such reasonable regulations as it may prescribe, the
Securities Registrar shall provide for the registration of Preferred Securities
Certificates and Common Securities Certificates (subject to Section 5.10 in the
case of the Common Securities Certificates) and registration of transfers and
exchanges of Preferred Securities Certificates as herein provided. The Property
Trustee shall be the initial Securities Registrar. The provisions of Sections
8.1, 8.3 and 8.6 shall apply to the Property Trustee also in its role as
Securities Registrar, for so long as the Property Trustee shall act as
Securities Registrar and, to the extent applicable, to any other securities
registrar appointed hereunder. Any reference in this Trust Agreement to the
Securities Registrar shall include any co-securities registrar unless the
context requires otherwise.

            Upon surrender for registration of transfer of any Preferred
Securities Certificate at the office or agency maintained pursuant to Section
5.8, the Administrative Trustees or any one of them shall execute and deliver,
in the name of the designated transferee or transferees, one or more new
Preferred Securities Certificates in authorized denominations of a like
aggregate Liquidation Amount dated the date of execution by such Administrative
Trustee or Trustees. The Securities Registrar shall not be required to register
the transfer of any Preferred Securities that have been called for redemption.
At the option of a Holder, Preferred Securities Certificates may be exchanged
for other Preferred Securities Certificates in authorized denominations of the
same class and of a like aggregate Liquidation Amount upon surrender of the
Preferred Securities Certificates to be exchanged at the office or agency
maintained pursuant to Section 5.8.

            Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Administrative Trustees and
the Securities Registrar duly executed by the Holder or his attorney duly
authorized in writing. Each Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be cancelled and subsequently
disposed of by the Administrative Trustees in accordance with their customary
practice.

            No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

         SECTION 5.5 MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.

            If (a) any mutilated Trust Securities Certificate shall be
surrendered to the Securities Registrar, or if the Securities Registrar shall
receive evidence to its satisfaction of the destruction,

                                       20
<PAGE>

loss or theft of any Trust Securities Certificate and (b) there shall be
delivered to the Securities Registrar and the Administrative Trustees such
security or indemnity as may be required by them to save each of them harmless,
then in the absence of notice that such Trust Securities Certificate shall have
been acquired by a protected purchaser, the Administrative Trustees, or any one
of them, on behalf of the Trust shall execute and make available for delivery,
in exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Trust Securities Certificate, a new Trust Securities Certificate of like class,
tenor and denomination. In connection with the issuance of any new Trust
Securities Certificate under this Section, the Administrative Trustees or the
Securities Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection therewith.
Any duplicate Trust Securities Certificate issued pursuant to this Section shall
constitute conclusive evidence of an undivided beneficial interest in the assets
of the Trust, as if originally issued, whether or not the lost, stolen or
destroyed Trust Securities Certificate shall be found at any time.

         SECTION 5.6 PERSONS DEEMED SECURITYHOLDERS.

            The Administrative Trustees or the Securities Registrar shall treat
the Person in whose name any Trust Securities Certificate shall be registered in
the Securities Register as the owner of such Trust Securities Certificate for
the purpose of receiving distributions and for all other purposes whatsoever,
and neither the Trustees nor the Securities Registrar shall be bound by any
notice to the contrary.

         SECTION 5.7 ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

            The Administrative Trustees or the Depositor shall furnish or cause
to be furnished (a) to the Property Trustee, semi-annually on or before January
15 and July 15 in each year, a list, in such form as the Property Trustee may
reasonably require, of the names and addresses of the Securityholders as of the
most recent Record Date and (b) to the Property Trustee, promptly after receipt
by any Administrative Trustee or the Depositor of a request therefor from the
Property Trustee in order to enable the Property Trustee to discharge its
obligations under this Trust Agreement, in each case to the extent such
information is in the possession or control of the Administrative Trustees or
the Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar. The rights of Securityholders to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under
the Trust Securities, and the corresponding rights of the Trustee shall be as
provided in the Trust Indenture Act. Each Holder, by receiving and holding a
Trust Securities Certificate, and each Owner shall be deemed to have agreed not
to hold the Depositor, the Property Trustee or the Administrative Trustees
accountable by reason of the disclosure of its name and address, regardless of
the source from which such information was derived.

         SECTION 5.8 MAINTENANCE OF OFFICE OR AGENCY.

            The Administrative Trustees shall maintain in The City of New York,
an office or offices or agency or agencies where Preferred Securities
Certificates may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Trustees in respect of the Trust
Securities Certificates may be served. The Administrative Trustees initially

                                       21
<PAGE>

designate -, as its principal corporate trust office for such purposes. The
Property Trustee shall give prompt written notice to the Depositor and to the
Securityholders of any change in the location of the Securities Register or any
such office or agency.

         SECTION 5.9 APPOINTMENT OF PAYING AGENT.

            The Paying Agent shall make distributions to Securityholders from
the Payment Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Property Trustee, and any co-paying agent chosen by the
Property Trustee, and acceptable to the Administrative Trustees and the
Depositor. Any Person acting as Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Administrative Trustees, the
Property Trustee and the Depositor. In the event that the Property Trustee shall
no longer be the Paying Agent or a successor Paying Agent shall resign or its
authority to act be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Property Trustee and the Depositor to act as
Paying Agent (which shall be a bank or trust company). The Administrative
Trustees shall cause such successor Paying Agent or any additional Paying Agent
appointed by the Administrative Trustees to execute and deliver to the Trustees
an instrument in which such successor Paying Agent or additional Paying Agent
shall agree with the Trustees that as Paying Agent, such successor Paying Agent
or additional Paying Agent will hold all sums, if any, held by it for payment to
the Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders. The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to
the Property Trustee. The provisions of Sections 8.1, 8.3 and 8.6 shall apply to
the Property Trustee also in its role as Paying Agent, for so long as the
Property Trustee shall act as Paying Agent and, to the extent applicable, to any
other paying agent appointed hereunder. Any reference in this Trust Agreement to
the Paying Agent shall include any co-paying agent unless the context requires
otherwise.

         SECTION 5.10 OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

            On the Closing Date and on each other date provided for in Section
2.5, the Depositor shall acquire and retain beneficial and record ownership of
the Common Securities. To the fullest extent permitted by law, except as
otherwise permitted under the Indenture, any attempted transfer of the Common
Securities shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST AGREEMENT (AS
DEFINED BELOW)".

         SECTION 5.11 BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

                                       22

            (a) The Preferred Securities Certificates, upon original issuance,
will be issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Trust. Such Preferred Securities Certificate or Certificates
shall initially be registered on the Securities Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no beneficial owner will
receive a Definitive Preferred Securities Certificate representing such
beneficial owner's interest in such Preferred Securities, except as provided in
Section 5.13. Unless and until Definitive Preferred Securities Certificates have
been issued to beneficial owners pursuant to Section 5.13:

                  (i) the provisions of this Section 5.11(a) shall be in full
   force and effect;

                  (ii) the Securities Registrar and the Trustees shall be
   entitled to deal with the Clearing Agency for all purposes of this Trust
   Agreement relating to the Book-Entry Preferred Securities Certificates
   (including the payment of principal of and interest on the Book-Entry
   Preferred Securities and the giving of instructions or directions to Owners
   of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
   Preferred Securities and shall have no obligations to the Owners thereof;

                  (iii) to the extent that the provisions of this Section 5.11
   conflict with any other provisions of this Trust Agreement, the provisions of
   this Section 5.11 shall control; and

                  (iv) the rights of the Owners of the Book-Entry Preferred
   Securities Certificates shall be exercised only through the Clearing Agency
   and shall be limited to those established by law and agreements between such
   Owners and the Clearing Agency and/or the Clearing Agency Participants.
   Pursuant to the Certificate Depository Agreement, unless and until Definitive
   Preferred Securities Certificates are issued pursuant to Section 5.13, the
   initial Clearing Agency will make book-entry transfers among the Clearing
   Agency Participants and receive and transmit payments on the Preferred
   Securities to such Clearing Agency Participants.

            (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

         SECTION 5.12 NOTICES TO CLEARING AGENCY.

            To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

         SECTION 5.13 DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

            If (a) the Depositor advises the Trustees in writing that the
Clearing Agency is no longer willing or able to properly discharge its
responsibilities with respect to the Preferred Securities

                                       23
<PAGE>

Certificates, and the Depositor is unable to locate a qualified successor, (b)
the Depositor at its option advises the Trustees in writing that it elects to
terminate the book-entry system through the Clearing Agency or (c) after the
occurrence of a Debenture Event of Default, Owners of Preferred Securities
Certificates representing beneficial interests aggregating at least a majority
of the Liquidation Amount advise the Clearing Agency in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Preferred Securities Certificates, then the
Clearing Agency shall notify all Owners of Preferred Securities Certificates and
the Trustees of the occurrence of any such event and of the availability of the
Definitive Preferred Securities Certificates to Owners of such class or classes,
as applicable, requesting the same. Upon surrender to the Administrative
Trustees of the typewritten Preferred Securities Certificate or Certificates
representing the Book Entry Preferred Securities Certificates by the Clearing
Agency, accompanied by registration instructions, the Administrative Trustees,
or any one of them, shall execute the Definitive Preferred Securities
Certificates in accordance with the instructions of the Clearing Agency. Neither
the Securities Registrar nor the Trustees shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Preferred Securities Certificates, the Trustees shall recognize the Holders of
the Definitive Preferred Securities Certificates as Securityholders. The
Definitive Preferred Securities Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

         SECTION 5.14 RIGHTS OF SECURITYHOLDERS.

            The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Trust Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

                                   ARTICLE VI
                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

         SECTION 6.1 LIMITATIONS ON VOTING RIGHTS.

            (a) Except as provided in this Section, in Sections 8.10 and 10.2
and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

                                       24
<PAGE>

            (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
outstanding Preferred Securities; provided, however, that where a consent under
the Indenture would require the consent of each holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior written consent of each holder of Preferred Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the
Preferred Securities, except by a subsequent vote of the Preferred Securities.

            The Property Trustee shall notify all Holders of the Preferred
Securities of any notice of default received from the Debenture Trustee with
respect to the Debentures. In addition to obtaining the foregoing approvals of
the Holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion
of Counsel experienced in such matters to the effect that the Trust will not be
classified as an association taxable as a corporation or partnership for United
States federal income tax purposes on account of such action.

            (c) If any proposed amendment to the Trust Agreement provides for,
or the Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities.

         SECTION 6.2 NOTICE OF MEETINGS.

            Notice of all meetings of the Preferred Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
upon receipt of written notice of the calling of such meeting from the
Administrative Trustees pursuant to Section 10.8 to each Preferred
Securityholder of record, at his registered address, at least 15 days and not
more than 90 days before the meeting. At any such meeting, any business properly
before the meeting may be so considered whether or not stated in the notice of
the meeting. Any adjourned meeting may be held as adjourned without further
notice.

         SECTION 6.3 MEETINGS OF PREFERRED SECURITYHOLDERS.

            No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% of the Preferred Securities (based upon

                                       25
<PAGE>

their Liquidation Amount) and the Administrative Trustees or the Property
Trustee may, at any time in their discretion, call a meeting of Preferred
Securityholders to vote on any matters as to which Preferred Securityholders are
entitled to vote.

            Preferred Securityholders of record of 50% of the Preferred
Securities (based upon their Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

            If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their Liquidation
Amount) held by the Preferred Securityholders of record present, either in
person or by proxy, at such meeting shall constitute the action of the
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

         SECTION 6.4 VOTING RIGHTS.

            Securityholders shall be entitled to one vote for each $___ of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.

         SECTION 6.5 PROXIES, ETC.

            At any meeting of Securityholders, any Securityholder entitled to
vote thereat may vote by proxy, provided that no proxy shall be voted at any
meeting unless it shall have been placed on file with the Administrative
Trustees, or with such other officer or agent of the Trust as the Administrative
Trustees may direct, for verification prior to the time at which such vote shall
be taken. Pursuant to a resolution of the Property Trustee, proxies may be
solicited in the name of the Property Trustee or one or more officers of the
Property Trustee. Only Securityholders of record shall be entitled to vote. When
Trust Securities are held jointly by several persons, any one of them may vote
at any meeting in person or by proxy in respect of such Trust Securities, but if
more than one of them shall be present at such meeting in person or by proxy,
and such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Trust Securities. A
proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

         SECTION 6.6 SECURITYHOLDER ACTION BY WRITTEN CONSENT.

            Any action which may be taken by Securityholders at a meeting may be
taken without prior notice and without a meeting if Securityholders holding more
than a majority of all Outstanding Trust Securities (based upon their
Liquidation Amount) entitled to vote in respect of such action (or such larger
proportion thereof as shall be required by any express provision of this Trust
Agreement) shall consent to the action in writing.

         SECTION 6.7 RECORD DATE FOR VOTING AND OTHER PURPOSES.

                                       26
<PAGE>

            For the purposes of determining the Securityholders who are entitled
to notice of and to vote at any meeting or by written consent, or to participate
in any distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, Administrative Trustees may from time to time fix a date, not more
than 90 days prior to the date of any meeting of Securityholders or the payment
of distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

         SECTION 6.8 ACTS OF SECURITYHOLDERS.

            Any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Trust Agreement to be
given, made or taken by Securityholders or Owners may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Securityholders or Owners in person or by an agent duly appointed in
writing; and, except as otherwise expressly provided herein, such action shall
become effective when such instrument or instruments are delivered to an
Administrative Trustee. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Securityholders or Owners signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.1) conclusive in favor of the Trustees, if made in the manner provided in this
Section.

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

            The ownership of Preferred Securities shall be proved by the
Securities Register.

            Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Securityholder of any Trust Security shall bind every
future Securityholder of the same Trust Security and the Securityholder of every
Trust 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 Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

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

                                       27
<PAGE>

            If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the dispute shall be submitted to an
independent legal counsel which has not provided significant services to any of
the disputing parties in the past two years (the "Independent Legal Counsel"),
and reasonably satisfactory to the disputing parties, for determination of such
matter. The Independent Legal Counsel's determination shall be conclusive and
binding with respect to such matter.

         SECTION 6.9 INSPECTION OF RECORDS.

            Upon reasonable notice to the Administrative Trustees and the
Property Trustee, the records of the Trust shall be open to inspection by
Securityholders during normal business hours for any purpose reasonably related
to such Securityholder's interest as a Securityholder.

         SECTION 7.2 REPRESENTATIONS AND WARRANTIES OF DEPOSITOR.

            The Depositor hereby represents and warrants for the benefit of the
Securityholders that:

            (a) the Trust Securities Certificates issued on the Closing Date on
behalf of the Trust have been duly authorized and will have been, duly and
validly executed, issued and delivered by the Trustees pursuant to the terms and
provisions of, and in accordance with the requirements of, this Trust Agreement
and the Securityholders will be, as of such date, entitled to the benefits of
this Trust Agreement; and

            (b) there are no taxes, fees or other governmental charges payable
by the Trust (or the Trustees on behalf of the Trust) under the laws of the
State of Delaware or under the laws of the State of New York or any political
subdivision thereof in connection with the execution, delivery and performance
by the Bank, the Property Trustee or the Delaware Trustee, as the case may be,
of this Trust Agreement.

                                  ARTICLE VIII
                                  THE TRUSTEES

         SECTION 8.1 CERTAIN DUTIES AND RESPONSIBILITIES.

            (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Trustees shall be subject to the provisions of this Section.
Nothing in this Trust Agreement shall be construed to release the Property
Trustee from liability for its own negligent action, its own failure to act, or
its own willful misconduct. To the extent that, at law or in equity, an
Administrative Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Administrative
Trustee shall not be liable

                                       30
<PAGE>

to the Trust or to any Securityholder for such Trustee's good faith reliance on
the provisions of this Trust Agreement. The provisions of this Trust Agreement,
to the extent that they restrict the duties and liabilities of the
Administrative Trustees otherwise existing at law or in equity, are agreed by
the Depositor and the Securityholders to replace such other duties and
liabilities of the Administrative Trustees.

            (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof. Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the revenue and proceeds from the Trust Property to the extent legally
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security. This
Section 8.1(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

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

                  (i) the Property Trustee shall not be liable for any error of
   judgment made in good faith by an authorized officer of the Property Trustee,
   unless it shall be proved that the Property Trustee was negligent in
   ascertaining the pertinent facts;

                  (ii) the Property Trustee shall not be liable with respect to
   any action taken or omitted to be taken by it in good faith in accordance
   with the direction of the holders of not less than a majority in Liquidation
   Amount of the Trust Securities relating to the time, method and place of
   conducting any proceeding for any remedy available to the Property Trustee,
   or exercising any trust or power conferred upon the Property Trustee under
   this Trust Agreement;

                  (iii) the Property Trustee's sole duty with respect to the
   custody, safe keeping and physical preservation of the Debentures and the
   Payment Account shall be to deal with such Property in a similar manner as
   the Property Trustee deals with similar property for its own account, subject
   to the protections and limitations on liability afforded to the Property
   Trustee under this Trust Agreement and the Trust Indenture Act;

                  (iv) the Property Trustee shall not be liable for any interest
   on any money received by it except as it may otherwise agree with the
   Depositor. Money held by the Property Trustee need not be segregated from
   other funds held by it except in relation to the Payment Account maintained
   by the Property Trustee pursuant to Section 3.1 and except to the extent
   otherwise required by law; and

                  (v) the Property Trustee shall not be responsible for
   monitoring the compliance by the Administrative Trustees or the Depositor
   with their respective duties under

                                       31
<PAGE>

   this Trust Agreement, nor shall the Property Trustee be liable for the
   default or misconduct of the Administrative Trustees or the Depositor.

         SECTION 8.2 NOTICE OF DEFAULTS.

            Within five Business Days after the occurrence of any Event of
Default actually known to a Responsible Officer of the Property Trustee, the
Property Trustee shall transmit, in the manner and to the extent provided in
Section 10.8, notice of such Event of Default to the Securityholders, the
Administrative Trustees and the Depositor, unless such Event of Default shall
have been cured or waived.

            Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to extend the interest payment period for the
Debentures pursuant to the Indenture, the Administrative Trustee shall transmit,
in the manner and to the extent provided in Section 10.8, notice of such
exercise to the Securityholders and the Property Trustee, unless such exercise
shall have been revoked.

         SECTION 8.3 CERTAIN RIGHTS OF PROPERTY TRUSTEE.

            Subject to the provisions of Section 8.1:

            (a) the Property Trustee may rely and shall be protected in acting
or refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

            (b) if, (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions in this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the Preferred Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken. The Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;

            (c) any direction or act of the Depositor or the Administrative
Trustees contemplated by this Trust Agreement shall be sufficiently evidenced by
an Officer's Certificate;

                                       32
<PAGE>

            (d) whenever in the administration of this Trust Agreement, the
Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and rely upon an Officer's Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

            (e) the Property Trustee shall have no duty to see to any recording,
filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

            (f) the Property Trustee may consult with counsel and the advice of
such counsel shall be full and complete authorization and protection in respect
of any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon and in accordance with such advice, such counsel may be counsel
to the Depositor or any of its Affiliates, and may include any of its employees.
The Property Trustee shall have the right at any time to seek instructions
concerning the administration of this Trust Agreement from any court of
competent jurisdiction;

            (g) the Property Trustee shall be under no obligation to exercise
any of the rights or powers vested in it by this Trust Agreement at the request
or direction of any of the Securityholders pursuant to this Trust Agreement,
unless such Securityholders shall have offered to the Property Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

            (h) the Property 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, consent, order,
approval, bond, debenture, note or other evidence of indebtedness or other paper
or document, unless requested in writing to do so by one or more
Securityholders, but the Property Trustee may make such further inquiry or
investigation into such facts or matters as it may see fit;

            (i) the Property Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through its
agents or attorneys, and the Property Trustee shall not be responsible for any
misconduct or negligence on the part of or for the supervision of, any such
agent or attorney appointed with due care by it hereunder;

            (j) whenever in the administration of this Trust Agreement the
Property Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee

                  (i) may request instructions from the Holders of the Trust
   Securities which instructions may only be given by the Holders of the same
   proportion in Liquidation Amount of the Trust Securities as would be entitled
   to direct the Property Trustee under the terms of the Trust Securities in
   respect of such remedy, right or action,

                  (ii) may refrain from enforcing such remedy or right or taking
   such other action until such instructions are received, and

                                       33
<PAGE>

                  (iii) shall be fully protected in acting in accordance with
   such instructions;

            (k) except as otherwise expressly provided by this Trust Agreement,
the Property Trustee shall not be under any obligation to take any action that
is discretionary under the provisions of this Trust Agreement; and

            (l) the Property Trustee shall not be charged with knowledge of an
Event of Default unless a Responsible Officer of the Property Trustee obtains
actual knowledge of such event or the Property Trustee receives written notice
of such event from any Securityholder, the Depositor or the Debenture Trustee.

            No provision of this Trust Agreement shall be deemed to impose any
duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Property Trustee
shall be construed to be a duty.

         SECTION 8.4 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

            The recitals contained herein and in the Trust Securities
Certificates shall be taken as the statements of the Trust, and the Trustees do
not assume any responsibility for their correctness. The Trustees shall not be
accountable for the use or application by the Depositor of the proceeds of the
Debentures.

         SECTION 8.5 MAY HOLD SECURITIES.

            Any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, subject to Sections 8.8 and 8.13 and except as provided in the
definition of the term "Outstanding" in Article I, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

         SECTION 8.6 COMPENSATION; INDEMNITY; FEES.

            The Depositor agrees:

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

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

                                       34
<PAGE>

            (c) to indemnify each of the Trustees and their officers, directors
and employees or any predecessor Trustee for, and to hold the Trustees harmless
against, any loss, damage, claims, liability, penalty or expense incurred
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this Trust Agreement, including the
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 (collectively, "Expenses"); and

            (d) to the fullest extent permitted by law, the Expenses (including
reasonable attorneys' fees and expenses) incurred by a Trustee referred to in
paragraph (c) of this Section 8.6 shall be paid by the Depositor in advance upon
receipt of an undertaking by or on behalf of such Trustee to repay such amount
if it shall ultimately be determined that such Trustee is not entitled to be
indemnified by the Depositor as authorized in this Section 8.6.

            No Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

         SECTION 8.7 CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF
TRUSTEES.

            (a) There shall at all times be a Property Trustee hereunder with
respect to the Trust Securities. The Property Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

            (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities. Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind that
entity.

            (c) There shall at all times be a Delaware Trustee with respect to
the Trust Securities. The Delaware Trustee shall either be (i) a natural person
who is at least 21 years of age and a resident of the State of Delaware or (ii)
a legal entity with its principal place of business in the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

         SECTION 8.8 CONFLICTING INTERESTS.

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

                                       35
<PAGE>

         SECTION 8.9 CO-TRUSTEES AND SEPARATE TRUSTEE.

            Unless an Event of Default shall have occurred and be continuing, at
any time or times, for the purpose of meeting the legal requirements of the
Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Depositor and the Administrative
Trustees, by agreed action of the majority of such Trustees, shall have power to
appoint, and upon the written request of the Administrative Trustees, the
Depositor shall for such purpose join with the Administrative Trustees in the
execution, delivery, and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Property Trustee
either to act as co-trustee, jointly with the Property Trustee, of all or any
part of such Trust Property, or to the extent required by law to act as separate
trustee of any such property, in either case with such powers as may be provided
in the instrument of appointment, and to vest in such Person or Persons in the
capacity aforesaid, any property, title, right or power deemed necessary or
desirable, subject to the other provisions of this Section. If the Depositor
does not join in such appointment within 15 days after the receipt by it of a
request so to do, or in case a Debenture Event of Default has occurred and is
continuing, the Property Trustee alone shall have power to make such
appointment. Any co-trustee or separate trustee appointed pursuant to this
Section shall either be

                  (i) a natural person who is at least 21 years of age and a
   resident of the United States or

                  (ii) a legal entity with its principal place of business in
   the United States that shall act through one or more persons authorized to
   bond such entity.

            Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged, and delivered
by the Depositor.

            Every co-trustee or separate trustee shall, to the extent permitted
by law, but to such extent only, be appointed subject to the following terms,
namely:

            (a) The Trust Securities shall be executed and delivered and all
rights, powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

            (b) The rights, powers, duties, and obligations hereby conferred or
imposed upon the Property Trustee in respect of any property covered by such
appointment shall be conferred or imposed upon and exercised or performed by the
Property Trustee or by the Property Trustee and such co-trustee or separate
trustee jointly, as shall be provided in the instrument appointing such
co-trustee or separate trustee, except to the extent that under any law of any
jurisdiction in which any particular act is to be performed, the Property
Trustee shall be incompetent or unqualified to perform such act, in which event
such rights, powers, duties, and obligations shall be exercised and performed by
such co-trustee or separate trustee.

                                       36
<PAGE>

            (c) The Property Trustee at any time, by an instrument in writing
executed by it, with the written concurrence of the Depositor, may accept the
resignation of or remove any co-trustee or separate trustee appointed under this
Section, and, in case an Event of Default under the Indenture has occurred and
is continuing, the Property Trustee shall have power to accept the resignation
of, or remove, any such co-trustee or separate trustee without the concurrence
of the Depositor. Upon the written request of the Property Trustee, the
Depositor shall join with the Property Trustee in the execution, delivery, and
performance of all instruments and agreements necessary or proper to effectuate
such resignation or removal. A successor to any co-trustee or separate trustee
so resigned or removed may be appointed in the manner provided in this Section.

            (d) No co-trustee or separate trustee hereunder shall be personally
liable by reason of any act or omission of the Property Trustee, or any other
trustee hereunder.

            (e) The Property Trustee shall not be liable by reason of any act of
a co-trustee or separate trustee.

            (f) Any Act of Holders delivered to the Property Trustee shall be
deemed to have been delivered to each such co-trustee and separate trustee.

         SECTION 8.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

            No resignation or removal of any Trustee (the "Relevant Trustee")
and no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

            Any Trustee may resign at any time with respect to the Trust
Securities by giving written notice thereof to the Securityholders. If the
instrument of acceptance by the successor Trustee required by Section 8.11 shall
not have been delivered to the Relevant Trustee within 30 days after the giving
of such notice of resignation, the Relevant Trustee may petition, at the expense
of the Depositor, any court of competent jurisdiction for the appointment of a
successor Relevant Trustee with respect to the Trust Securities.

            Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time.

            If any Trustee shall resign, be removed or become incapable of
acting as Trustee, or if a vacancy shall occur in the office of any Trustee for
any cause, at a time when no Debenture Event of Default shall have occurred and
be continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees with respect to the Trust Securities and the Trust, and the retiring
Trustee shall comply with the applicable requirements of Section 8.11. If the
Property Trustee or the Delaware Trustee shall resign, be removed or become
incapable of continuing to act as the Property

                                       37
<PAGE>

Trustee or the Delaware Trustee, as the case may be, at a time when a Debenture
Event of Default is continuing, the Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the Preferred Securities
then Outstanding delivered to the retiring Relevant Trustee, shall promptly
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 8.11.

            If an Administrative Trustee shall resign, be removed or become
incapable of acting as Administrative Trustee, at a time when a Debenture Event
of Default shall have occurred and be continuing, the Common Securityholder
shall appoint a successor or Administrative Trustees. If no successor Relevant
Trustee with respect to the Trust Securities shall have been so appointed by the
Common Securityholder or the Preferred Securityholders and accepted appointment
in the manner required by Section 8.11, any Securityholder who has been a
Securityholder of Trust Securities 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 Relevant Trustee with respect to
the Trust Securities.

            The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.8 and shall give notice to
the Depositor, in each case promptly upon receipt by it of notice of such
resignation. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Property
Trustee.

            Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 8.7).

         SECTION 8.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

            In case of the appointment hereunder of a successor Trustee such
successor Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor 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 if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee hereunder.

            In case of the appointment hereunder of a successor Relevant Trustee
with respect to the Trust Securities and the Trust, the retiring Relevant
Trustee (if requested by the Depositor) and each successor Relevant Trustee with
respect to the Trust Securities shall execute and deliver

                                       38
<PAGE>

an amendment hereto wherein each successor Relevant Trustee shall accept such
appointment and which

            (a) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Relevant Trustee all
the rights, powers, trusts and duties of the retiring Relevant Trustee with
respect to the Trust Securities and the Trust and

            (b) shall add to or change any of the provisions of this Trust
Agreement as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Relevant Trustee, it being understood
that nothing herein or in such amendment shall constitute such Relevant Trustees
co-trustees of the same trust and that each such Relevant Trustee shall be
trustee of a trust or trusts hereunder separate and apart from any trust or
trusts hereunder administered by any other such Relevant Trustee and upon the
execution and delivery of such amendment the resignation or removal of the
retiring Relevant Trustee shall become effective to the extent provided therein
and each such successor Relevant Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Relevant Trustee with respect to the Trust Securities and the
Trust; but, on request of the Trust or any successor Relevant Trustee such
retiring Relevant Trustee shall duly assign, transfer and deliver to such
successor Relevant Trustee all Trust Property, all proceeds thereof and money
held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

            Upon request of any such successor Relevant Trustee, the Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the first or second preceding paragraph, as the case may be.

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

         SECTION 8.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO

it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which such Relevant Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of such Relevant Trustee, shall be the successor of such Relevant 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.

         SECTION 8.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR
TRUST.

            If and when the Property Trustee or the Delaware Trustee shall be or
become a creditor of the Depositor or the Trust (or any other obligor upon the

                                       39
<PAGE>

provisions of the Trust Indenture Act regarding the collection of claims against
the Depositor or Trust (or any such other obligor).

         SECTION 8.14 REPORTS BY PROPERTY TRUSTEE.

            (a) Within 60 days after December 31 of each year commencing with

                  (i) its eligibility under Section 8.7 or, in lieu thereof, if

   Section, a written statement to such effect;

                  (ii) a statement that the Property Trustee has complied with
   all of its obligations under this Trust Agreement during the twelve-month
   period (or, in the case of the initial report, the period since the Closing
   Date) ending with such December 31 or, if the Property Trustee has not
   complied in any material respect with such obligations, a description of such
   noncompliance; and

                  (iii) any change in the property and funds in its possession

   the Property Trustee in the performance of its duties hereunder which it has
   not previously reported and which in its opinion materially affects the Trust
   Securities.

            (b) In addition the Property Trustee shall transmit to
Securityholders and the Depositor such reports concerning the Property Trustee
and its actions under this Trust Agreement as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto.

            (c) A copy of each such report shall, at the time of such
transmission to the Depositor, be filed by the Depositor with each stock
exchange upon which the Trust Securities are listed and with the Commission.

of Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the
number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

            (c) The death, resignation, retirement, removal, bankruptcy,

appointment of an Administrative Trustee in accordance with Section 8.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Trust Agreement), shall have all the

                       DISSOLUTION, LIQUIDATION AND MERGER

         SECTION 9.1 DISSOLUTION UPON EXPIRATION DATE.

            Unless earlier dissolved, the Trust shall automatically dissolve on

         SECTION 9.2 EARLY DISSOLUTION.

                                       41
<PAGE>

            The first to occur of any of the following events is an "Early
Termination Event", upon the occurrence of which the Trust shall be dissolved:

            (a) the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor;

            (b) the occurrence of a Tax Event or an Investment Company Event
(each, a "Special Event"), or the Trust is or will not be taxed as a grantor
trust but a Tax Event has not occurred (a "Grantor Trust Event"), and written
direction is given to the Property Trustee from the Depositor within 45 days of
such Special Event or Grantor Trust Event (which direction is optional and
wholly within the discretion of the Depositor) to dissolve the Trust and
distribute Debentures to Securityholders in accordance with Section 9.4;

            (c) the redemption of all of the Preferred Securities; and

            (d) an order for dissolution of the Trust shall have been entered by
a court of competent jurisdiction.

         SECTION 9.3 TERMINATION.

            The respective obligations and responsibilities of the Trustees and
the Trust created and continued hereby shall terminate upon the latest to occur
of the following:

            (a) the distribution by the Property Trustee to Securityholders upon
the liquidation of the Trust pursuant to Section 9.4, or upon the redemption of
all of the Trust Securities pursuant to Section 4.2, of all amounts required to
be distributed hereunder upon the final payment of the Trust Securities;

            (b) the payment of any expenses owed by the Trust; and

            (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders.

         SECTION 9.4 LIQUIDATION.

            (a) If an Early Termination Event specified in clause (a), (b) or
(d) of Section 9.2 occurs or upon the Expiration Date, the Trust shall be
liquidated by the Trustees as expeditiously as the Trustees determine to be
possible by distributing, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, to each Securityholder a Like Amount of
Debentures, subject to Section 9.4(d). Notice of liquidation shall be given by
the Property Trustee by first-class mail, postage prepaid, mailed not later than
30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust
Securities at such Holder's address appearing in the Securities Register. All
notices of liquidation shall:

                  (i) state the Liquidation Date;

                                       42
<PAGE>

                  (ii) state that from and after the Liquidation Date, the Trust
   Securities will no longer be deemed to be outstanding and any Trust
   Securities Certificates not surrendered for exchange will be deemed to
   represent a Like Amount of Debentures; and

                  (iii) provide such information with respect to the mechanics
   by which Holders may exchange Trust Securities Certificates for Debentures,
   or if Section 9.4(d) applies receive a Liquidation Distribution, as the
   Administrative Trustees or the Property Trustee shall deem appropriate.

            (b) Except where Section 9.2(c) or 9.4(d) applies, in order to
effect the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

            (c) Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its reasonable efforts to have the Debentures listed on
the New York Stock Exchange or on such other exchange as the Preferred
Securities are then listed, (iv) any Trust Securities Certificates not so
surrendered for exchange will be deemed to represent a Like Amount of
Debentures, accruing interest at the rate provided for in the Debentures from
the last Distribution Date on which a Distribution was made on such Trust
Certificates until such certificates are so surrendered (and until such
certificates are so surrendered, no payments or interest or principal will be
made to holders of Trust Securities Certificates with respect to such
Debentures) and (iv) all rights of Securityholders holding Trust Securities will
cease, except the right of such Securityholders to receive Debentures upon
surrender of Trust Securities Certificates.

            (d) In the event that, notwithstanding the other provisions of this
Section 9.4, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
wound-up by the Property Trustee in such manner as the Property Trustee
determines. In such event, Securityholders will be entitled to receive out of
the assets of the Trust available for distribution to Securityholders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the Liquidation Amount per Trust Security plus accrued
and unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If, upon any such winding up the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then, subject
to the next succeeding sentence, the amounts payable by the Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The Holder of the Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution, winding-up or termination pro rata
(determined as aforesaid) with Holders of Preferred Securities, except that, if
a Debenture Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities.

         SECTION 9.5 MERGERS, CONSOLIDATIONS OR REPLACEMENTS OF THE TRUST.

            The Trust may not merge with or into, consolidate or be replaced by,
or convey, transfer or lease its properties and assets substantially as an
entirety to any corporation or other body, except pursuant to this Section 9.5
or Section 9.4. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the holders of the Preferred
Securities, the Trust may merge with or into, consolidate or be replaced by a
trust organized as such under the laws of any State; provided, that

            (i) such successor entity either

                  (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or

                  (b) substitutes for the Preferred Securities other securities
having substantially the same terms as the Preferred Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Preferred
Securities rank in priority with respect to distributions and payments upon
liquidation, redemption and otherwise,

            (ii) the Depositor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures,

            (iii) the Successor Securities are listed, or any Successor
Securities will be listed upon notification of issuance, on any national
securities exchange or other organization on which the Preferred Securities are
then listed, if any,

            (iv) such merger, consolidation or replacement does not cause the
Preferred Securities (including any Successor Securities) to be downgraded by
any nationally recognized statistical rating organization,

            (v) such merger, consolidation or replacement does not adversely
affect the rights, preferences and privilege of the holders of the Preferred
Securities (including any Successor Securities) in any material respect,

            (vi) such successor entity has a purpose substantially identical to
that of the Trust,

            (vii) prior to such merger, consolidation or replacement, the
Depositor has received an Opinion of Counsel to the effect that

                  (a) such merger, consolidation or replacement does not
adversely affect the rights, preferences and privileges of the holders of the
Preferred Securities (including any Successor Securities) in any material
respect, and

                  (b) following such merger, consolidation or replacement,
neither the Trust nor such successor entity will be required to register as an
investment company under the 1940 Act and

                                       44
<PAGE>

            (viii) the Depositor owns all of the common securities of such
successor entity and guarantees the obligations of such successor entity under
the Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
merge with or into, or be replaced by any other entity or permit any other
entity to consolidate, merge with or into, or replace it if such consolidation,
merger or replacement would cause the Trust or the successor entity to be
classified as other than a grantor trust for federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1 LIMITATION OF RIGHTS OF SECURITYHOLDERS.

            The death or incapacity of any Person having an interest, beneficial
or otherwise, in Trust Securities shall not operate to terminate this Trust
Agreement, nor annul, dissolve or terminate the Trust, nor entitle the legal
representatives or heirs of such person or any Securityholder for such person,
to claim an accounting, take any action or bring any proceeding in any court for
a partition or winding up of the arrangements contemplated hereby, nor otherwise
affect the rights, obligations and liabilities of the parties hereto or any of
them.

         SECTION 10.2 AMENDMENT.

            (a) This Trust Agreement may be amended from time to time by the
Administrative Trustees and the Depositor, without the consent of any
Securityholders,

                  (i) to cure any ambiguity, correct or supplement any provision
   herein or therein which may be inconsistent with any other provision herein
   or therein, or to make any other provisions with respect to matters or
   questions arising under this Trust Agreement, which shall not be inconsistent
   with the other provisions of this Trust Agreement, or

                  (ii) to modify, eliminate or add to any provisions of this
   Trust Agreement to such extent as shall be necessary to ensure that the Trust
   will be classified for Federal income tax purposes as a grantor trust at all
   times that any Trust Securities are outstanding or to ensure that the Trust
   will not be required to register as an "investment company" under the 1940
   Act; provided, however, that in the case of clause (i), such action shall not
   adversely affect in any material respect the interests of any Securityholder,
   and any such amendments of this Trust Agreement shall become effective when
   notice thereof is given to the Securityholders.

            (b) Except as provided in Section 10.2(c) hereof, any provision of
this Trust Agreement may be amended by the Administrative Trustees and the
Depositor with

                  (i) the consent of Trust Securityholders representing not less
   than a majority (based upon Liquidation Amounts) of the Trust Securities then
   Outstanding and

                  (ii) receipt by the Trustees of an Opinion of Counsel to the
   effect that such amendment or the exercise of any power granted to the
   Trustees in accordance with

                                       45
<PAGE>

   such amendment will not affect the Trust's status as a grantor trust for
   federal income tax purposes or the Trust's exemption from status of an
   "investment company" under the 1940 Act.

            (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder, this Trust
Agreement may not be amended to

   Trust Securities or otherwise adversely affect the amount of any Distribution
   required to be made in respect of the Trust Securities as of a specified date
   or

                  (ii) restrict the right of a Securityholder to institute suit
   for the enforcement of any such payment on or after such date;
   notwithstanding any other provision herein without the unanimous consent of
   the Securityholders, this paragraph (c) of this Section 10.2 may not be
   amended.

            (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an "investment company" under the 1940 Act.

            (e) Notwithstanding anything in this Trust Agreement to the
contrary, without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

            (f) In the event that any amendment to this Trust Agreement is made,
the Administrative Trustees shall promptly provide to the Depositor a copy of
such amendment.

            (g) No amendment to this Trust Agreement shall be adopted that
affects the Property Trustee's or the Delaware Trustee's rights, duties or
immunities under this Trust Agreement without the consent of the Property
Trustee or the Delaware Trustee, as the case may be. The Property Trustee shall
be entitled to receive and conclusively rely on an Opinion of Counsel and an
Officer's Certificate stating that any amendment to this Trust Agreement is in
compliance with this Trust Agreement.

         SECTION 10.3 SEPARABILITY.

            In case any provision in this Trust Agreement or in the Trust
Securities Certificates shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

         SECTION 10.4 GOVERNING LAW.

or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded

Agreement by any of the provisions of the Trust Indenture Act, such required
provision shall control. If any provision of this Trust Agreement 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 Trust Agreement
as so modified or to be excluded, as the case may be.

            (d) The application of the Trust Indenture Act to this Trust
Agreement shall not affect the nature of the Securities as equity securities

Re: AmerUs Capital _____ Preferred Securities

Ladies and Gentlemen:

            The purpose of this letter is to set forth certain matters relating
to the issuance and deposit with The Depository Trust Company ("DTC") of the
AmerUs Capital _____ _________% Preferred Securities, Series A (the "Preferred
Securities"), of AmerUs Capital _____, a Delaware statutory trust (the
"Issuer"), formed pursuant to a Trust Agreement between AmerUs Group Co.
("AmerUs") and The Bank of New York Trust Company, N.A., as Trustee. The payment
of distributions on the Preferred Securities to the extent the Issuer has funds
available for the payment thereof, and payments due upon liquidation of Issuer
or redemption of the Preferred Securities are guaranteed by AmerUs to the extent
set forth in a Guarantee Agreement, dated -, 200-, by AmerUs with respect to the
Preferred Securities. AmerUs and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated -, 200-, by and among the Underwriters, the Issuer
and AmerUs dated -, 200- and the Underwriters wish to take delivery of the
Preferred Securities through DTC. __________ is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

            To induce DTC to accept the Preferred Securities as eligible for
deposit at DTC, and to act in accordance with DTC's rules with respect to the
Preferred Securities, the Issuer, the Transfer Agent and Registrar and DTC agree
among each other as follows:

            1. Prior to the closing of the sale of the Preferred Securities to
the Underwriters, which is expected to occur on or about _____, 200-, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's
Preferred Securities nominee, Cede & Co., representing an aggregate of
_____________ Preferred Securities and bearing the following legend:

Unless this certificate is presented by an authorized representative of DTC, to
Issuer or its agent for registration of transfer, exchange, or payment, and any
certificate issued is registered in the name of Cede & Co. or in such other name
as is requested by an authorized representative of DTC (and any payment is made
to Cede & Co. or to such other entity as is requested by an authorized
representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

<PAGE>

            2. The Amended and Restated Trust Agreement of the Issuer provides
for the voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

            3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

            4. In the event of distribution on, or an offering or issuance of
rights with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212)
855-4555. Such notices by mail or by any other means shall be sent to:

Manager, Announcements
Dividend Department
The Depository Trust Company
55 Water Street, 25th Floor

            The Issuer or the Transfer Agent and Registrar shall confirm DTC's
receipt of such telecopy by telephoning the Dividend Department at (212)
855-4550.

            5. In the event of a redemption by the Issuer of the Preferred
Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4. Such redemption notice shall be
sent to DTC's Call Notification Department at (212)855-7232, (212) 855-7233 or
(212)

                                        2

855-7234 and receipt of such notice shall be confirmed by telephoning (212)
855-7207. Notice by mail or by any other means shall be sent to:

Call Notification Department
The Depository Trust Company
55 Water Street, 50th Floor
New York, New York 10041

            6. In the event of any invitation to tender the Preferred
Securities, notice specifying the terms of the tender and the Publication Date
of such notice shall be sent by the Issuer or the Transfer Agent and Registrar
to DTC by a secure means and in a timely manner as described in paragraph 4.
Notices to DTC pursuant to this paragraph and notices of other corporate actions
(including mandatory tenders, exchanges and capital changes), shall be sent,
unless notification to another department is expressly provided for herein, by
telecopy to DTC's Reorganization Department at (212) 855-5240 or (212) 855-5488
and receipt of such notice shall be confirmed by telephoning (212) 855-5235 or
(212) 855-5489, or by mail or any other means to:

Manager, Reorganization Department
Reorganization Window
The Depository Trust Company
55 Water Street, 50th Floor
New York, New York 10041

            7. All notices and payment advices sent to DTC shall contain the
CUSIP number or numbers of the Preferred Securities and the accompanying
designation of the Preferred Securities, which, as of the date of this letter is
"AmerUs Capital _____ _____% Preferred Securities."

            8. Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in next day funds on
each payment date (or in accordance with existing arrangements between the
Issuer or the Transfer Agent and Registrar and DTC). Such payments shall be made
payable to the order of Cede & Co., and shall be addressed as follows:

NDFS Redemption Department
The Depository Trust Company
55 Water Street, 25th Floor
New York, New York 10041

            9. DTC may by prior written notice direct the Issuer and the
Transfer Agent and Registrar to use any other telecopy number or address of DTC
as the number or address to which notices or payments may be sent.

            10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion: (a) may request the Issuer or the

                                        3
<PAGE>

Transfer Agent and Registrar to issue and countersign a new Global Certificate;
or (b) may make an appropriate notation on the Global Certificate indicating the
date and amount of such reduction.

            11. DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

            12. In the event that the Issuer determines that beneficial owners
of Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates. In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

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

Nothing herein shall be deemed to require the Transfer Agent and Registrar to
advance funds on behalf of AmerUs Capital _____.

Guarantee Agreement that relate to any of the matters set forth in Section
3.14(c) of the Trust Indenture Act. Any certificate or opinion required to be
given by an officer pursuant to Section 3.14(c)(1) may be given in the form of
an Officers' Certificate.

            Section 2.6 Events of Default; Waiver.

            The Holders of a Majority in liquidation preference of the Preferred
Securities may, by vote, on behalf of the Holders, waive any past Event of
Default and its consequences. Upon such waiver, any such Event of Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured, for every purpose of this Guarantee Agreement, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent therefrom.

            Section 2.7 Event of Default; Notice.

            (a) The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders, notices of all Events of Default actually known to a Responsible
Officer of the Guarantee Trustee, unless such defaults have been cured before
the giving of such notice, provided, that, except in the case of a default in
the payment of a Guarantee Payment, the Guarantee Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a

                                       5
<PAGE>

trust committee of directors and/or Responsible Officers of the Guarantee
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders.

            (b) The Guarantee Trustee shall not be deemed to have knowledge of
any Event of Default unless a Responsible Officer of the Guarantee Trustee shall
have received written notice of such Event of Default.

            Section 2.8 Conflicting Interests.

            The Trust Agreement shall be deemed to be specifically described in
this Guarantee Agreement for the purposes of clause (i) of the first proviso
contained in Section 3.10(b) of the Trust Indenture Act.

                                   ARTICLE III
               POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

            Section 3.1 Powers and Duties of the Guarantee Trustee.

            (a) This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.04(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder, and
such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

            (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall, promptly upon receipt of written notice of such Event
of Default, enforce this Guarantee Agreement for the benefit of the Holders.

            (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied duties or covenants shall be read into
this Guarantee Agreement against the Guarantee Trustee. In case an Event of
Default has occurred (that has not been cured or waived pursuant to Section
2.6), the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Guarantee Agreement, and use the same degree of care and skill in
its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

                  (i) prior to the occurrence of any Event of Default and after
      the curing or waiving of all such Events of Default that may have
      occurred:

<PAGE>

                        (A) the duties and obligations of the Guarantee Trustee
            shall be determined solely by the express provisions of this
            Guarantee Agreement, and the Guarantee Trustee shall not be liable
            except for the performance of such duties and obligations as are
            specifically set forth in this Guarantee Agreement; and

                        (B) in the absence of bad faith on the part of the
            Guarantee Trustee, the Guarantee Trustee may conclusively rely, as
            to the truth of the statements and the correctness of the opinions
            expressed therein, upon any certificates or opinions furnished to
            the Guarantee Trustee and conforming to the requirements of this
            Guarantee Agreement; but in the case of any such certificates or
            opinions that by any provision hereof or of the Trust Indenture Act
            are specifically required to be furnished to the Guarantee Trustee,
            the Guarantee Trustee shall be under a duty to examine the same to
            determine whether or not they conform on their face to the
            requirements of this Guarantee Agreement;

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

                  (iii) the Guarantee Trustee shall not be liable with respect
      to any action taken or omitted to be taken by it in good faith in
      accordance with the direction of the Holders of not less than a Majority
      in liquidation preference of the Preferred Securities relating to the
      time, method and place of conducting any proceeding for any remedy
      available to the Guarantee Trustee, or exercising any trust or power
      conferred upon the Guarantee Trustee under this Guarantee Agreement; and

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

            Section 3.2 Certain Rights of Guarantee Trustee.

            (a) Subject to the provisions of Section 3.01:

                  (i) The Guarantee Trustee may rely and shall be fully
      protected in acting or refraining from acting upon any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      direction, consent, order, bond, debenture, note, other evidence of
      indebtedness or other paper or document believed by it to be genuine and
      to have been signed, sent or presented by the proper party or parties.

                  (ii) Any direction or act of the Guarantor contemplated by
      this Guarantee Agreement shall be sufficiently evidenced by an Officers'
      Certificate unless otherwise prescribed herein.

                                       7
<PAGE>

                  (iii) Whenever, in the administration of this Guarantee
      Agreement, the Guarantee Trustee shall deem it desirable that a matter be
      proved or established before taking, suffering or omitting to take any
      action hereunder, the Guarantee Trustee (unless other evidence is herein
      specifically prescribed) may, in the absence of bad faith on its part,
      request and rely upon an Officers' Certificate which, upon receipt of such
      request from the Guarantee Trustee, shall be promptly delivered by the
      Guarantor.

                  (iv) The Guarantee Trustee may consult with legal counsel, and
      the written advice or opinion of such legal counsel with respect to legal
      matters shall be full and complete authorization and protection in respect
      of any action taken, suffered or omitted to be taken by it hereunder in
      good faith and in accordance with such advice or opinion. Such legal
      counsel may be legal counsel to the Guarantor or any of its Affiliates and
      may be one of its employees. The Guarantee Trustee shall have the right at
      any time to seek instructions concerning the administration of this
      Guarantee Agreement from any court of competent jurisdiction.

                  (v) The Guarantee Trustee shall be under no obligation to
      exercise any of the rights or powers vested in it by this Guarantee
      Agreement at the request or direction of any Holder, unless such Holder
      shall have provided to the Guarantee Trustee such adequate security and
      indemnity as would satisfy a reasonable person in the position of the
      Guarantee Trustee, against the costs, expenses (including attorneys' fees
      and expenses) and liabilities that might be incurred by it in complying
      with such request or direction, including such reasonable advances as may
      be requested by the Guarantee Trustee; provided that, nothing contained in
      this Section 3.2(a)(v) shall be taken to relieve the Guarantee Trustee,
      upon the occurrence of an Event of Default, of its obligation to exercise
      the rights and powers vested in it by this Guarantee Agreement.

                  (vi) The Guarantee 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 Guarantee Trustee, in its
      discretion, may make such further inquiry or investigation into such facts
      or matters as it may see fit.

                  (vii) The Guarantee Trustee may execute any of the trusts or
      powers hereunder or perform any duties hereunder either directly or by or
      through its agents or attorneys, and the Guarantee Trustee shall not be
      responsible for any misconduct or negligence on the part of, or for the
      supervision of, any such agent or attorney appointed with due care by it
      hereunder.

                  (viii) Whenever in the administration of this Guarantee
      Agreement the Guarantee Trustee shall deem it desirable to receive
      instructions with respect to enforcing any remedy or right or taking any
      other action hereunder, the Guarantee Trustee (A) may request instructions
      from the Holders, (B) may refrain from enforcing such remedy or right or
      taking such other action until such instructions are received, and (C)
      shall be protected in acting in accordance with such instructions.

                                       8
<PAGE>

            (b) No provision of this Guarantee Agreement shall be deemed to
impose any duty or obligation on the Guarantee Trustee to perform any act or
acts or exercise any right, power, duty or obligation conferred or imposed on it
in any jurisdiction in which it shall be illegal, or in which the Guarantee
Trustee shall be unqualified or incompetent in accordance with applicable law,
to perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

            Section 3.3 Indemnity.

            The Guarantor agrees to indemnify the Guarantee Trustee and its
officers, directors and employees for, and to hold each harmless against, any
loss, liability or expense incurred without negligence or bad faith on the part
of the Guarantee Trustee, arising out of or in connection with the acceptance or
administration of this Guarantee Agreement, including the 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 (collectively,
"Expenses"). The Guarantee Trustee will not claim or exact any lien or charge on
any Guarantee Payments as a result of any amount due to it under this Guarantee
Agreement. To the fullest extent permitted by law, the Expenses incurred by the
Guarantee Trustee referred to above shall be paid by the Guarantor in advance
upon receipt of an undertaking by or on behalf of the Guarantee Trustee to repay
such amount if it shall ultimately be determined that the Guarantee Trustee is
not entitled to be indemnified by the Guarantor as authorized in this Section
3.3. The obligations of the Guarantor under this Section 3.3 shall survive
termination of this Guarantee Agreement and the removal or resignation of any
Guarantee Trustee.

                                GUARANTEE TRUSTEE

            Section 4.1 Guarantee Trustee; Eligibility.

            (a) There shall at all times be a Guarantee Trustee which shall:

                  (i) not be an Affiliate of the Guarantor; and

                  (ii) be a Person that is eligible pursuant to the Trust
      Indenture Act to act as such and has a combined capital and surplus of at
      least 50 million U.S. dollars ($50,000,000), and shall be a corporation
      meeting the requirements of Section 3.10(c) of the Trust Indenture Act. If
      such corporation publishes reports of condition at least annually,
      pursuant to law or to the requirements of the supervising or examining
      authority, then, for the purposes of this Section and to the extent
      permitted by the Trust Indenture Act, the combined capital and surplus of
      such corporation shall be deemed to be its combined capital and surplus as
      set forth in its most recent report of condition so published.

            (b) If at any time the Guarantee Trustee shall cease to be eligible
to so act under Section 4.1(a), the Guarantee Trustee shall immediately resign
in the manner and with the effect set out in Section 4.2(c).

                                       9
<PAGE>

            (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 3.10(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the provisions
of Section 3.10(b) of the Trust Indenture Act.

            Section 4.2 Appointment, Removal and Resignation of the Guarantee
Trustee.

            (a) Subject to Section 4.2(b), the Guarantee Trustee may be
appointed or removed without cause at any time by the Guarantor.

            (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered to
the Guarantor.

            (c) The Guarantee Trustee appointed hereunder shall hold office
until a Successor Guarantee Trustee shall have been appointed or until its
removal or resignation. The Guarantee Trustee may resign from office (without
need for prior or subsequent accounting) by an instrument in writing executed by
the Guarantee Trustee and delivered to the Guarantor, which resignation shall
not take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

            (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

            The Guarantor irrevocably and unconditionally agrees to pay in full
to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by or on behalf of the Issuer), as and when due, regardless of
any defense, right of set-off or counterclaim which the Issuer may have or
assert. The Guarantor's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

            Section 5.2 Waiver of Notice and Demand.

            The Guarantor hereby waives notice of acceptance of the Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the
Guarantee Trustee, Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

            (b) the extension of time for the payment by the Issuer of all or
any portion of the Distributions (other than an extension of time for payment of
Distributions that results from the extension of any interest payment period on
the Debentures as so provided in the Indenture), Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Preferred
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Preferred Securities;

            (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer granting indulgence or extension of any
kind;

            (d) the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of debt
of, or other similar proceedings affecting, the Issuer or any of the assets of
the Issuer;

            (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

            (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

            (g) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the
consent of, the Guarantor with respect to the happening of any of the foregoing.

            Section 5.4 Rights of Holders.

            The Guarantor expressly acknowledges that: (i) this Guarantee
Agreement will be deposited with the Guarantee Trustee to be held for the
benefit of the Holders; (ii) the Guarantee Trustee has the right to enforce this
Guarantee Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Preferred Securities have the right to direct the

<PAGE>

upon the Guarantee Trustee under this Guarantee Agreement; and (iv) any Holder
may institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Guarantee Trustee, the Issuer or any other Person.

            Section 5.5 Guarantee of Payment.

            This Guarantee Agreement creates a guarantee of payment and not of
collection. This Guarantee Agreement will not be discharged except by payment of
the Guarantee Payments in full (without duplication of amounts theretofore paid
by the Issuer) or upon distribution of Debentures to Holders as provided in the
Trust Agreement.

            Section 5.6 Subrogation.

            The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

            The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Preferred
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

            Section 6.1 Subordination.

            This Guarantee Agreement will constitute an unsecured obligation of
the Guarantor and will rank subordinate and junior in right of payment to all
Senior Debt of the Guarantor.

            Section 6.2 Pari Passu Guarantees.

            This Guarantee Agreement shall rank pari passu with any similar

            Section 7.1 Termination.

            This Guarantee Agreement shall terminate and be of no further force
and effect upon (i) full payment of the Redemption Price of all Preferred
Securities, (ii) the distribution of Debentures to the Holders in exchange for
all of the Preferred Securities or (iii) full payment of the amounts payable in
accordance with the Trust Agreement upon liquidation of the Issuer.
Notwithstanding the foregoing, this Guarantee Agreement will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
must restore payment of any sums paid with respect to Preferred Securities or
this Guarantee Agreement.

                                  ARTICLE VIII

            Section 8.2 Amendments.

            Any amendment to this Guarantee Agreement shall be in writing and
executed by the Guarantor and Guarantee Trustee. Except with respect to any
changes which do not adversely affect the rights of the Holders in any material
respect (in which case no consent of the Holders will be required), this
Guarantee Agreement may only be amended with the prior approval of the Holders
of not less than a Majority in liquidation preference of all the outstanding
Preferred Securities. The provisions of Article VI of the Trust Agreement
concerning meetings of the Holders shall apply to the giving of such approval.
The Guarantee Trustee shall not be required to enter into any amendment to this
