Item 5. Other Events

     On December 20, 1996, the Registrant completed the sale of $200 million of
7.94% Capital Securities, Series A (the "Capital Securities") issued by State
Street Institutional Capital A (the "Trust"), a newly created subsidiary
business trust of the Registrant.  The Capital Securities are fully guaranteed
by the Registrant.  In connection with the sale of the Capital Securities, the
Registrant issued and sold to the Trust $206 million of its 7.94% Junior

     Neither the Capital Securities nor the Debentures have been registered
under the Securities Act of 1933, as amended (the "Securities Act"), and may not
be offered or sold in the United States absent registration under, or an
applicable exemption from, the registration requirements of the Securities Act
and applicable state securities laws.

     Section 1.2. Compliance Certificate and Opinions.

     Upon any application or request by the Corporation to the Trustee to take
any action under any provision of this Indenture, the Corporation shall furnish
to the Trustee an Officers' Certificate stating that all conditions precedent
(including covenants compliance with which constitutes a condition precedent),
if any, provided for in this Indenture relating to the proposed action have been
complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent (including covenants compliance with which
constitutes a condition precedent), if any, have been complied with, except that
in the case of any such application or request as to which the furnishing of
such documents is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or
opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (other than the certificates provided
pursuant to Section 10.4) shall include:

     (1)  a statement by each individual signing such certificate or opinion
that such individual has read such covenant or condition and the definitions
herein relating thereto;

     (2)  a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions of such individual contained
in such certificate or opinion are based;

     (3)  a statement that, in the opinion of such individual, he or she has
made such examination or investigation as is necessary to enable him or her to
express an informed opinion as to whether or not such covenant or condition has
been complied with; and

     (4)  a statement as to whether, in the opinion of such individual, such
condition or covenant has been complied with.

     Section 1.3. 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 Corporation 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 matters upon which his or her 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 Corporation stating that the
information with respect to such factual matters is in the possession of the
Corporation, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

     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 1.4. 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 Corporation. 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 6.1) conclusive in favor of the Trustee and
the Corporation, 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 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 or her the execution thereof.
Where such execution is by a Person acting in other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her 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 that 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 Corporation in reliance thereon,
whether or not notation of such action is made upon such Security.

     (f)  The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Corporation 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 succeeding paragraph.
If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date, provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
(as defined below) by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph

                                      -11-
<PAGE>
 
shall be construed to prevent the Corporation from setting a new record date for
any action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Corporation, at its own expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities 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 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(2), or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date, provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding 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 Corporation's expense, shall
cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Corporation in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section
1.6.

     With respect to any record date set pursuant to this Section, the party
hereto that sets such record date may designate any day as the "Expiration Date"
and from time to time may change the Expiration Date to any earlier or later
day, provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

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

     Section 1.5. Notices, Etc. to Trustee and Corporation.

     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, any holder of Capital Securities or the
Corporation shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at its Corporate Trust
office, or

     (2)  the Corporation by the Trustee, any Holder or any holder of Capital
Securities shall be sufficient for every purpose (except as otherwise provided
in Section 5.1) hereunder if in writing and mailed, first class, postage
prepaid, to the Corporation 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 Corporation.

     Section 1.6. 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. If, by reason of the suspension
of or irregularities in regular mail service or for any other reason, it shall
be impossible or impracticable to mail notice of any event to Holders when said
notice is required to be given pursuant to any provision of this Indenture or of
the relevant Securities, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice. In any case where notice to Holders 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 1.7. Conflict with Trust Indenture Act.

     Except as otherwise expressly provided herein, the Trust Indenture Act
shall apply as a matter of contract to this Indenture for purposes of
interpretation, construction and defining the rights and obligations hereunder,
and this Indenture, the Corporation, and the Trustee shall be deemed for all
purposes hereof to be subject to and governed by the Trust Indenture Act to the
same extent as would be the case if this Indenture were qualified under that Act
on the date hereof. Except as otherwise provided herein, if and to the extent
that any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by any of Sections 310 to 317, inclusive, of the Trust Indenture
Act through operation of Section 318(c) thereof, such imposed duties shall
control.

     Section 1.8. Effect of Headings and Table of Contents.

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

     Section 1.9. Successors and Assigns.

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

     Section 1.10. Separability Clause.

     If 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 and their successors and
assigns, the holders of Senior Indebtedness, the Holders of the Securities and,
to the extent expressly provided in Sections 5.1, 5.2, 5.8, 5.9, 5.11, 5.13, 9.1
and 9.2, the holders of Capital Securities, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

     Section 1.12. Governing Law.

     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     Section 1.13. Non-Business Days.

     If any Interest Payment Date, Redemption 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 (and
premium, if any) or other amounts in respect of such Security need not be made
on such date, but may be made on the next succeeding Business Day (and no
interest shall accrue in respect of the amounts whose payment is so delayed for
the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, until such next succeeding Business Day) except
that, if such Business Day falls in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day (in each case
with the same force and effect as if made on the Interest Payment Date or
Redemption Date or at the Stated Maturity).

as may be required to comply with applicable tax laws or the rules of any
securities exchange or as may, consistently herewith, be determined by the

action shall be certified by the Secretary or an Assistant Secretary of the
Corporation and delivered to the Trustee at or prior to the delivery of the
Corporation Order contemplated by Section 3.3 with respect to the authentication

includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to _______________, or registered
assigns, the principal sum of __________ Dollars on __________ __, [if the
Security is a Global Security, then insert, if applicable--, or such other
principal amount represented hereby as may be set forth in the records of the
Securities Registrar hereinafter referred to in accordance with the Indenture,]

principal of this Security to a date not earlier than __________, and (ii)
extend the Stated Maturity of the principal of this Security at any time on one
or more occasions, subject to certain conditions specified in Section 3.15 of

further promises to pay interest on said principal sum from _______________, ___
or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, [monthly] [quarterly] [semi-annually] [if applicable, 
insert--(subject to deferral as set forth herein)] in arrears on [insert
applicable Interest Payment Dates] of each year, commencing _______________,
___, at the rate of ___% per annum, [if applicable insert--together with
Additional Sums, if any, as provided in Section 10.6 of the Indenture] until the

Sums and any overdue installment of interest shall bear Additional Interest at
the rate of____% per annum (to the extent that the payment of such interest
shall be legally enforceable), compounded [monthly] [quarterly] [semi-annually],
from the dates such amounts are due until they are paid or made available for
payment, and such interest shall be payable on demand]. The amount of interest
payable for any period less than a full interest period shall be computed on the
basis of a 360-day year of twelve 30-day months and the actual days elapsed in a

     [If applicable, insert--So long as no Event of Default has occurred and is
continuing, the Corporation shall have the right, at any time during the term of
this Security, from time to time to defer the payment of interest on this
Security for up to ______ consecutive [monthly] [quarterly] [semi-annual]
interest payment periods with respect to each deferral period (each an
"Extension Period") [If applicable, insert--, during which Extension Periods the
Corporation shall have the right to make partial payments of interest on any
Interest Payment Date, and] at the end of which the Corporation shall pay all
interest then accrued and unpaid including any Additional Interest, as provided
below; provided, however, that no Extension Period shall extend beyond the
Stated Maturity of the principal of this Security [If Stated Maturity can be
shortened or extended, insert--, as then in effect,] and no such Extension
Period may end on a date other than an Interest Payment Date; and provided,
further, however, that during any such Extension Period, the Corporation shall
not (i) make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities of the Corporation that rank
pari passu in all respects with or junior in interest to this Security, or (ii)
declare or pay any dividends or distributions on, or redeem, purchase, acquire
or make a liquidation payment with respect to, any of the Corporation's capital
stock (other than (a) repurchases, redemptions or other acquisitions of shares
of capital stock of the Corporation in connection with any employment contract,
benefit plan or other similar arrangement with or for the benefit of any one or
more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Corporation (or securities convertible into
or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a Subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any Rights Plan, or the issuance of
rights, stock or other property under any Rights Plan, or the redemption or
repurchase of rights pursuant thereto, or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock). Prior to the termination of any such Extension Period, the
Corporation may further defer the payment of interest, provided that no
Extension Period shall exceed ______ consecutive [monthly] [quarterly] [semi-
annual] interest payment periods, extend beyond the Stated Maturity of the
principal of this Security or end on a date other than an Interest Payment Date.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due on any Interest
Payment Date, the Corporation may elect to begin a new Extension Period, subject
to the above conditions. No interest shall be due and payable during an
Extension Period, except at the end thereof, but each installment of interest
that would otherwise have been due and payable during such Extension shall bear
Additional Interest (to the extent that the payment of such interest shall be
legally enforceable) at the rate of ____% per annum, compounded [monthly]
[quarterly] [semi-annually] and calculated as set forth in the first paragraph
of this Security, from the dates on which amounts would otherwise have been due
and payable until paid or made available for payment. The Corporation shall give
the Holder of this Security and the Trustee notice of its election to begin any
Extension Period at least one Business Day prior to the next succeeding Interest
Payment Date on which interest on this Security would be payable but for such
deferral [if applicable, insert--or so long as such Securities are held by
[insert name of applicable Issuer Trust], at least one Business Day prior to the
earlier of (i) the next succeeding date on which Distributions on the Capital
Securities of such Issuer Trust would be payable but for such deferral,

                                      -17-

and (ii) the date on which the Property Trustee of such Issuer Trust is required
to give notice to holders of such Capital Securities of the record date or the
date such Distributions are payable].

     Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Corporation maintained for
that purpose in the [insert Place of Payment], 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 Corporation 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 junior in right of payment to the prior payment
in full of all Senior Indebtedness, 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 or her behalf to take such actions as
may be necessary or appropriate to effectuate the subordination so provided, and
(c) appoints the Trustee his or her attorney-in-fact for any and all such
purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice
of the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly
executed under its corporate seal.

specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Corporation with certain provisions of the Indenture

interest on any overdue principal, premium and interest (in each case to the
extent that the payment of such interest shall be legally enforceable), all of
the Corporation's obligations in respect of the payment of the principal of and
premium and interest, if any, on this Security shall terminate.]

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Corporation, which
is absolute and unconditional, to pay the principal of (and premium, if any) and

such purpose, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Corporation and the Securities Registrar
duly executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Securities of this series, of like tenor,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $____________ and any integral multiple of
$____________ in excess thereof. As provided in the Indenture and subject to
certain limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series
and of like tenor of a different authorized denomination, as requested by the
Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Corporation may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security be overdue, and neither the
Corporation, the Trustee nor any such agent shall be affected by notice to the
contrary.

     The Corporation and, by its acceptance of this Security or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Security agree that for United States Federal, state and local
tax purposes it is intended that this Security constitute indebtedness.

     THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE

     The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced or impressed thereon
and attested by its Secretary or one of its Assistant Secretaries. The signature
of any of these officers on the Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Corporation shall bind the
Corporation, 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 Corporation
may deliver Securities of any series executed 

                                      -25-
<PAGE>
 
by the Corporation to the Trustee for authentication, together with a
Corporation Order for the authentication and delivery of such Securities, and
the Trustee in accordance with the Corporation Order shall authenticate and
deliver such Securities. If the form or terms of the Securities of the series
have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 2.1 and 3.1, 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 6.1) shall be fully protected in relying upon, an Opinion of Counsel
stating,

          (1)  if the form of such Securities has been established by or
     pursuant to Board Resolution as permitted by Section 2.1, that such form
     has been established in conformity with the provisions of this Indenture;

          (2)  if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 3.1, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

          (3)  that such Securities, when authenticated and delivered by the
     Trustee and issued by the Corporation in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Corporation, subject to bankruptcy,
     insolvency, fraudulent transfer, reorganization, moratorium and similar
     laws of general applicability relating to or affecting creditors' rights
     and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner that
is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Corporation Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

     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. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 3.10, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

     SECTION 3.4. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Corporation Order the Trustee shall
authenticate and deliver, temporary Securities that 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 Corporation 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 Corporation designated for that
purpose without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities, the Corporation shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any 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 of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.


     SECTION 3.5. Global Securities.

     (a)  Each Global Security issued under this Indenture shall be registered
in the name of the Depositary designated by the Corporation for such Global
Security or a nominee thereof and delivered to such Depositary or a nominee
thereof or custodian therefor, and each such Global Security shall constitute a
single Security for all purposes of this Indenture.

     (b)  Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (i) such Depositary advises the Trustee in writing that such
Depositary is no longer willing or able to properly discharge its
responsibilities as Depositary with respect to such Global Security, and the
Corporation is unable to locate a qualified successor, (ii) the Corporation
executes and delivers to the Trustee a Corporation Order stating that the
Corporation elects to terminate the book-entry system through the Depositary,
(iii) there shall have occurred and be continuing an Event of Default, or (iv)
in the case of a transfer of a beneficial interest in such Security to a Person
that is not a "qualified institutional buyer" within the meaning of Rule 144A
under the Securities Act, upon reasonable prior notice of such transfer by the
Depositary or its authorized representative to the Securities Registrar and
delivery to the Securities Registrar of a Restricted Securities Certificate duly
authorized by the Depositary or its authorized representative to the Securities
Registrar and delivery to the Securities Registrar of a Restricted Securities
Certificate duly authorized by the Depositary or its authorized representatives.

     (c)  If any Global Security is to be exchanged for other Securities or
cancelled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Securities Registrar for exchange or cancellation as provided
in this Article III. If any Global Security is to be exchanged for other
Securities or cancelled in part, or if another Security is to be exchanged in
whole or in part for a

                                      -27-

beneficial interest in any Global Security, then either (i) such Global Security
shall be so surrendered for exchange or cancellation as provided in this Article
III or (ii) the principal amount thereof shall be reduced, subject to Section
3.6(b)(v), or increased by an amount equal to the portion thereof to be so
exchanged or cancelled, or equal to the principal amount of such other Security
to be so exchanged for a beneficial interest therein, as the case may be, by
means of an appropriate adjustment made on the records of the Securities
Registrar, whereupon the Trustee, in accordance with the Applicable Procedures,
shall instruct the Depositary or its authorized representative to make a
corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Security by the Depositary, accompanied by registration
instructions, the Trustee shall, subject to Section 3.5(b) and as otherwise
provided in this Article III, authenticate and deliver any Securities issuable
in exchange for such Global Security (or any portion thereof) in accordance with
the instructions of the Depositary. The Trustee shall not be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be fully protected in relying on, such instructions.

     (d)  Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article III, Section 9.6 or 11.6 or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof.

     (e)  Securities distributed to holders of Book-Entry Capital Securities (as
defined in the applicable Trust Agreement) upon the dissolution of an Issuer
Trust shall be distributed in the form of one or more Global Securities
registered in the name of a Depositary or its nominee, and deposited with the
Securities Registrar, as custodian for such Depositary, or with such Depositary,
for credit by the Depositary to the respective accounts of the beneficial owners
of the Securities represented thereby (or such other accounts as they may
direct). Securities distributed to holders of Capital Securities other than 
Book-Entry Capital Securities upon the dissolution of an Issuer Trust shall not
be issued in the form of a Global Security or any other form intended to
facilitate book-entry trading in beneficial interests in such Securities.

     (f)  The Depositary or its nominee, as the registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under
this Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security shall be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members.
Neither the Trustee nor the Securities Registrar shall have any liability in
respect of any transfers effected by the Depositary.

     (g)  The rights of owners of beneficial interests in a Global Security
shall be exercised only through the Depositary and shall be limited to those
established by law and agreements between such owners and the Depositary and/or
its Agent Members.

     SECTION 3.6. Registration, Transfer and Exchange Generally; Certain
Transfers and Exchanges; Securities Act Legends.

     (a)  The Corporation 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 Corporation shall provide for the registration of Securities
and of transfers of Securities. Such register is herein sometimes referred to

                                      -28-
<PAGE>
 
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 offices
or agencies of the Corporation designated for that purpose the Corporation shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series of any authorized denominations of like tenor and aggregate principal
amount and bearing such restrictive legends as may be required by this
Indenture.

     At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of like tenor and
aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any securities are so surrendered for exchange,
the Corporation shall execute, and the Trustee shall authenticate and deliver,
the Securities that 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 Corporation, 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 Corporation or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Corporation and the Securities Registrar, duly executed by the Holder thereof or
such Holder's attorney duly authorized in writing.

     No service charge shall be made to a Holder for any transfer or exchange of
Securities, but the Corporation 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.

     Neither the Corporation nor the Trustee shall be required, pursuant to the
provisions of this Section, (i) to issue, register the transfer of 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 of that series
pursuant to Article XI and ending at the close of business on the day of mailing
of the notice of redemption, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except, in the case of
any such Security to be redeemed in part, any portion thereof not to be
redeemed.

     (b)  Certain Transfers and Exchanges. Notwithstanding any other provision
of this Indenture, transfers and exchanges of Securities and beneficial
interests in a Global Security shall be made only in accordance with this
Section 3.6(b).

     (i)  Restricted Non-Global Security to Global Security. If the Holder of a
Restricted Security (other than a Global Security) wishes at any time to
transfer all or any portion of such Security to a Person who wishes to take
delivery thereof in the form of a beneficial interest in a Global Security, such
transfer may be effected only in accordance with the provisions of this Clause
(b)(i) and subject to the Applicable Procedures. Upon receipt by the Securities
Registrar of (A) such Security as provided in Section 3.6(a) and instructions
satisfactory to the Securities Registrar directing that a beneficial interest in
the Global

                                      -29-
<PAGE>
 
Security in a specified principal amount not greater than the principal amount
of such Security be credited to a specified Agent Member's account and (B) a
Restricted Securities Certificate duly executed by such Holder or such Holder's
attorney duly authorized in writing, then the Securities Registrar shall cancel
such Security (and issue a new Security in respect of any untransferred portion
thereof) as provided in Section 3.6(a) and increase the aggregate principal
amount of the Global Security by the specified principal amount as provided as
provided in Section 3.5(c).

     (ii)  Non-Global Security to Non-Global Security. A Security that is not a
Global Security may be transferred, in whole or in part, to a Person who takes
delivery in the form of another Security that is not a Global Security as
provided in Section 3.6(a), provided that if the Security to be transferred in
whole or in part is a Restricted Security, the Securities Registrar shall have
received a Restricted Securities Certificate duly executed by the transferor
Holder or such Holder's attorney duly authorized in writing.

     (iii) Exchanges Between Global Security and Non-Global Security. A
beneficial interest in a Global Security may be exchanged for a Security that is
not a Global Security as provided in Section 3.5.

     (iv)  Certain Initial Transfers of Non-Global Securities. In the case of
Securities initially issued other than in global form, an initial transfer or
exchange of such Securities that does not involve any change in beneficial
ownership may be made to an Institutional Accredited Investor or Investors as if
such transfer or exchange were not an initial transfer or exchange; provided
that written certification shall be provided by the transferee and transferor of
such Securities to the Securities Registrar that such transfer or exchange does
not involve a change in beneficial ownership.

     (v)   Limitations relating to Principal Amount. Notwithstanding any other
provision of this Indenture and unless otherwise specified as permitted by
Section 3.1, Securities or portions thereof may be transferred or exchanged only
in principal amounts of not less than $100,000. Any transfer, exchange or other
disposition of Securities in contravention of this Section 3.6(b)(v) shall be
deemed to be void and of no legal effect whatsoever, any such transferee shall
be deemed not to be the Holder or owner of any beneficial interest in such
Securities for any purpose, including but not limited to the receipt of interest
payable on such Securities, and such transferee shall be deemed to have no
interest whatsoever in such Securities.

     (c)   Restricted Securities Legend. Except as set forth below, all
Securities shall bear a Restricted Securities Legend:

     (i)   subject to the following Clauses of this Section 3.6(c), a Security
or any portion thereof that is exchanged, upon transfer or otherwise, for a
Global Security or any portion thereof shall bear the Restricted Securities
Legend while represented thereby;

     (ii)  subject to the following Clauses of this Section 3.6(c), a new
Security which is not a Global Security and is issued in exchange for another
Security (including a Global Security) or any portion thereof, upon transfer or
otherwise, shall bear a Restricted Securities Legend;

     (iii) a new Security (other than a Global Security) that does not bear a
Restricted Securities Legend may be issued in exchange for or in lieu of a
Restricted Security or any portion thereof that bears such a legend if, in the
Corporation's judgment, placing such a legend upon such new Security is not

                                      -30-
<PAGE>
 
necessary to ensure compliance with the registration requirements of the
Securities Act, and the Trustee, at the written direction of the Corporation in
the form of an Officers' Certificate, shall authenticate and deliver such a new
Security as provided in this Article III;

     (iv)  notwithstanding the foregoing provisions of this Section 3.6(c), a
Successor Security of a Security that does not bear a Restricted Securities
Legend shall not bear such form of legend unless the Corporation has reasonable
cause to believe that such Successor Security is a "restricted security" within
the meaning of Rule 144, in which case the Trustee, at the written direction of
the Corporation in the form of an Officers' Certificate, shall authenticate and
deliver a new Security bearing a Restricted Securities Legend in exchange for
such Successor Security as provided in this Article III; and

     (v)   Securities distributed to a holder of Capital Securities upon
dissolution of an Issuer Trust shall bear a Restricted Securities Legend if the
Capital Securities so held bear a similar legend.

     SECTION 3.7. 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 Corporation or the Trustee to
save each of them harmless, the Corporation shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series,
of like tenor and aggregate principal amount, bearing the same legends, and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Corporation 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 Corporation or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Corporation 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 series, of like tenor and aggregate principal amount and
bearing the same legends as such destroyed, lost or stolen Security, and bearing
a number not contemporaneously outstanding.

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

     Upon the issuance of any new Security under this Section, the Corporation
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 Corporation, 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 of the same series duly issued hereunder.

                                      -31-
<PAGE>
 
     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 3.8. Payment of Interest and Additional Interest; Interest Rights
Preserved.

     Interest and Additional Interest on any Security of any series that 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 and
any Additional Interest payable on the Stated Maturity of the principal 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 that 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 3.1
with respect to the related series of Securities.

     Any interest on any Security that is due and 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 Corporation, at
its election in each case, as provided in Clause (1) or (2) below:

     (1) The Corporation 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
Corporation 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 Corporation 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
Corporation of such Special Record Date and, in the name and at the expense of
the Corporation, 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 Corporation, 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).

                                      -32-
<PAGE>
 
     (2) The Corporation 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
Corporation 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, that were carried by such other Security.

     SECTION 3.9. Persons Deemed Owners.

     The Corporation, the Trustee and any agent of the Corporation or the
Trustee shall 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 3.8) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation or the Trustee shall
be affected by notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such Global Security, and such Depositary may be treated by the Corporation,
the Trustee and any agent of the Corporation or the Trustee as the owner of such
Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Corporation, the Trustee or any agent of the
Corporation or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by a Depositary or impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary (or its
nominee) as Holder of any Security.

     SECTION 3.10. 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 Corporation
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder that the Corporation 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 destroyed by the Trustee and the Trustee shall deliver to the Corporation a
certificate of such destruction.

     SECTION 3.11. Computation of Interest.

     Except as otherwise specified as contemplated by Section 3.1 for Securities
of any series, interest on the Securities of each series for any partial period
shall be computed on the basis of a 360-day year of twelve 30-day months and the
actual number of days elapsed in any partial month in such period, and interest
on the Securities of each series for a full period shall be computed by dividing
the rate per annum by the number of interest periods that together constitute a
full twelve months.

                                      -33-
<PAGE>
 
     SECTION 3.12. Deferrals of Interest Payment Dates.

     If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Corporation shall have the right, at any time
during the term of such series, from time to time to defer the payment of
interest on such Securities for such period or periods as may be specified as
contemplated by Section 3.1 (each, an "Extension Period"), during which
Extension Periods the Corporation shall, if so specified as contemplated by
Section 3.1, have the right to make partial payments of interest on any Interest
Payment Date. No Extension Period shall end on a date other than an Interest
Payment Date. At the end of any such Extension Period the Corporation shall pay
all interest then accrued and unpaid on the Securities (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 no
Extension Period shall extend beyond the Stated Maturity of the principal of the
Securities of such series; and provided further, however that during any such
Extension Period, the Corporation shall not (i) make any payment of principal of
or interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Corporation that rank pari passu in all respects with or
junior in interest to the Securities of such series, or (ii) declare or pay any
dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Corporation's capital stock
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Corporation in connection with any employment contract,
benefit plan or other similar arrangement with or for the benefit of any one or
more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Corporation (or securities convertible into
or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a Subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any Rights Plan, or the issuance of
rights, stock or other property under any Rights Plan, or the redemption or
repurchase of rights pursuant thereto, or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock). Prior to the termination of any such Extension Period, the
Corporation may further defer the payment of interest, provided that no Event of
Default has occurred and is continuing, and provided, further that no Extension
Period shall exceed the period or periods specified in such Securities, extend
beyond the Stated Maturity of the principal of such Securities or end on a date
other than an Interest Payment Date. Upon the termination of any such Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Corporation may
elect to begin a new Extension Period, subject to the above conditions. No
interest or Additional Interest shall be due and payable during an Extension
Period, except at the end thereof, but each installment of interest that would
otherwise have been due and payable during such Extension Period shall bear
Additional Interest as and to the extent as may be specified as contemplated by
Section 3.1. The Corporation shall give the Holders of the Securities of such
series and the Trustee notice of its election to begin any such Extension Period
at least one Business Day prior to the next succeeding Interest Payment Date on
which interest on Securities of such series would be payable but for such
deferral or, with respect to any Securities of a series issued to an Issuer
Trust, so long as any such Securities are held

                                      -34-
<PAGE>
 
by such Issuer Trust, at least one Business Day prior to the earlier of (i) the
next succeeding date on which Distributions on the Capital Securities of such
Issuer Trust would be payable but for such deferral, and (ii) the date on which
the Property Trustee of such Issuer Trust is required to give notice to holders
of such Capital Securities of the record date or the date such Distributions are
payable.

     The Trustee shall promptly give notice of the Corporation's election to
begin any such Extension Period to the Holders of the Outstanding Securities of
such series.

     SECTION 3.13. Right of Set-Off.

     With respect to the Securities of a series initially issued to an Issuer
Trust, notwithstanding anything to the contrary herein, the Corporation shall
have the right to set off any payment it is otherwise required to make in
respect of any such Security to the extent the Corporation has theretofore made,
or is concurrently on the date of such payment making, a payment under the
Guarantee Agreement relating to such Security or to a holder of Capital
Securities pursuant to an action undertaken under Section 5.8 of this Indenture.

     SECTION 3.14. Agreed Tax Treatment.

     Each Security issued hereunder shall provide that the Corporation 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 constitutes indebtedness.

     SECTION 3.15. Shortening or Extension of Stated Maturity.

     If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, the Corporation shall have the right to
(i) shorten the Stated Maturity of the principal of the Securities of such
series at any time to any date, and (ii) extend the Stated Maturity of the
principal of the Securities of such series at any time at its election for one
or more periods, provided that, if the Corporation elects to exercise its right
to extend the Stated Maturity of the principal of the Securities of such series
pursuant to Clause (ii) above, at the time such election is made and at the time
of extension, such conditions as may be specified in such Securities shall have
been satisfied.

     SECTION 3.16. CUSIP Numbers.

     The Corporation 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 and other similar or related materials as a convenience to
Holders; provided that any such notice or other materials 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 redemption or other materials
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.

                          SATISFACTION AND DISCHARGE

     SECTION 4.1. Satisfaction and Discharge of Indenture.

     This Indenture shall, upon Corporation Request, cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for and as otherwise provided
in this Section 4.1) and the Trustee, on demand of and at the expense of the
Corporation, 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 that have been destroyed, lost or stolen and that have
     been replaced or paid as provided in Section 3.7 and (ii) Securities for
     whose payment money has theretofore been deposited in trust or segregated
     and held in trust by the Corporation and thereafter repaid to the
     Corporation or discharged from such trust, as provided in Section 10.3)
     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, or

          (iii) are to be called for redemption within one year under
                arrangements satisfactory to the Trustee for the giving of
                notice of redemption by the Trustee in the name, and at the
                expense, of the Corporation,

     and the Corporation, in the case of subclause (B)(i), (ii) or (iii) 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 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 that have become due and payable) or to the Stated
     Maturity or Redemption Date, as the case may be;

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

     (3)  the Corporation 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.

                                      -36-

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Corporation to the Trustee under Section 6.7, the obligations
of the Trustee to any Authenticating Agent under Section 6.14 and, if money
shall have been deposited with the Trustee pursuant to subclause (B) of Clause
(1) of this Section, the obligations of the Trustee under Section 4.2 and the

     SECTION 4.2. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.3, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by the Trustee, in accordance with the provisions of the Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Corporation 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 (including any Additional Interest) for the payment of which

                                   ARTICLE V

                                   REMEDIES

     SECTION 5.1. 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) except
as may be specified pursuant to Section 3.1:

     (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 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)  failure on the part of the Corporation duly to observe or perform any
other of the covenants or agreements on the part of the Corporation in the
Securities of that series or in this Indenture for a period of 90 days after the
date on which written notice of such failure, requiring the Corporation to
remedy the same, shall have been given to the Corporation by the Trustee by
registered or certified mail or to the Corporation and the Trustee by the
Holders of at least 25% in aggregate principal amount of the Outstanding
Securities of that series; or

     (4)  the entry of a decree or order by a court having jurisdiction in the
premises adjudging the Corporation a bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization of the Corporation under the
Bankruptcy Code or any other similar applicable Federal or State law, which
decree or order shall have continued undischarged and unstayed for a period of
60 days; or the entry of

                                      -37-
<PAGE>
 
a decree or order of a court having jurisdiction in the premises for the
appointment of a receiver or liquidator or trustee or assignee in bankruptcy or
insolvency of the Corporation or of its property, or for the winding up or
liquidation of its affairs, which decree or order shall have continued
undischarged and unstayed for a period of 60 days; or

     (5)  the commencement by the Corporation of voluntary proceedings to be
adjudicated a bankrupt, or consent by the Corporation to the filing of a
bankruptcy proceeding against it, or the filing by the Corporation of a petition
or answer or consent seeking reorganization under the Bankruptcy Code or any
other similar Federal or State law, or consent by the Corporation to the filing
of any such petition, or the consent by the Corporation to the appointment of a
receiver or liquidator or trustee or assignee in bankruptcy or insolvency of it
or of its property, or the making by the Corporation of an assignment for the
benefit of creditors, or the admission by the Corporation in writing of its
inability to pay its debts generally as they become due; or

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

     SECTION 5.2. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
5.1(4) or 5.1(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 aggregate principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
the Securities of that series are 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 Corporation (and to the Trustee if given by Holders), provided
that, in the case of the Securities of a series issued to an Issuer 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 such series fail to declare
the principal of all the Outstanding Securities of such series to be immediately
due and payable, the holders of at least 25% in aggregate Liquidation Amount (as
defined in the related Trust Agreement) of the related series of Capital
Securities issued by such Issuer Trust then outstanding shall have the right to
make such declaration by a notice in writing to the Corporation and the Trustee;
and upon any such declaration such principal amount (or specified portion
thereof) of and the accrued interest (including any Additional Interest) on all
the Securities of such series shall become immediately due and payable. If an
Event of Default specified in Section 5.1(4) or 5.1(5) with respect to
Securities of any series at the time Outstanding occurs, the principal amount of
all the Securities of such series (or, if the Securities of such series are
Discount Securities, such portion of the principal amount of such Securities as
may be specified by the terms of that series) shall automatically, and without
any declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable. Payment of principal and interest (including any
Additional Interest) on such Securities shall remain subordinated to the extent
provided in Article XIII notwithstanding that such amount shall become
immediately due and payable as herein provided.

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

                                      -38-
<PAGE>
 
     (1)  the Corporation has paid or deposited with the Trustee a sum
sufficient to pay:

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

     (B)  any accrued Additional Interest on all Securities of such series,

     (C)  the principal of (and premium, if any, on) any Securities of such
series that have become due otherwise than by such declaration of acceleration
and interest and Additional Interest thereon 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 that has
become due solely by such acceleration, have been cured or waived as provided in
Section 5.13.

     In the case of Securities of a series initially issued to an Issuer Trust,
if the Holders of such Securities fail to annul such declaration and waive such
default, the holders of a majority in aggregate Liquidation Amount (as defined
in the related Trust Agreement) of the related series of Capital Securities
issued by such Issuer Trust then outstanding shall also have the right to
rescind and annul such declaration and its consequences by written notice to the
Corporation and the Trustee, subject to the satisfaction of the conditions set
forth in Clauses (1) and (2) above of this Section 5.2.

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

     SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by
Trustee.

     The Corporation covenants that if:

     (1)  default is made in the payment of any installment of interest
(including any Additional Interest) on any Security of any series 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 Corporation will, upon demand of the Trustee, pay to the Trustee, 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), and, in addition thereto, all amounts owing the Trustee
under Section 6.7.

     If the Corporation 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 Corporation or any other obligor upon such Securities and collect
the moneys adjudged 

                                      -39-
<PAGE>
 
or decreed to be payable in the manner provided by law out of the property of
the Corporation 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.

     Section 5.4. Trustee May File Proofs of Claim.

     In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Corporation or any other obligor upon the Securities
or the property of the Corporation 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 Corporation 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 6.7 allowed in any such judicial proceedings;
          and

               (ii) 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 5.6;
          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 5.6, 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 6.7.

     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; 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 5.5. Trustee May Enforce Claim 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, subject to
Article XIII and after provision for the payment of all the amounts owing the
Trustee and any predecessor Trustee under Section 6.7, 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 5.6. 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 (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 6.7;

     SECOND: Subject to Article XIII, to the payment of the amounts then due and
unpaid upon Securities of such series 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 Person or Persons entitled thereto.

     Section 5.7. Limitation on Suits.

     Subject to Section 5.8, 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 aggregate 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
against the costs, expenses and liabilities to be incurred in compliance with
such request;

                                      -41-
<PAGE>
 
     (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 aggregate
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 itself 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 5.8. Unconditional Right of Holders to Receive Principal, Premium
and Interest; Direct Action by Holders of Capital Securities.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security of any series shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and
(subject to Sections 3.8 and 3.12) interest (including any Additional Interest)
on such Security on the respective Stated Maturities expressed in such Security
(or, in the case of redemption, on the Redemption Date) 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 an Issuer Trust, any registered holder of the series of Capital Securities
issued by such Issuer Trust shall have the right, upon the occurrence of an
Event of Default described in Section 5.1(1) or 5.1(2), to institute a suit
directly against the Corporation for enforcement of payment to such holder of
principal of (premium, if any) and (subject to Sections 3.8 and 3.12) interest
(including any Additional Interest) on the Securities having a principal amount
equal to the aggregate Liquidation Amount (as defined in the related Trust
Agreement) of such Capital Securities held by such holder.

     Section 5.9. Restoration of Rights and Remedies.

     If the Trustee, any Holder or any holder of Capital Securities issued by
any Issuer Trust 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, such Holder or such
holder of Capital Securities, then and in every such case the Corporation, the
Trustee, such Holders and such holder of Capital Securities 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, such Holder and such holder of Capital Securities 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 3.7, 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

                                      -42-
<PAGE>
 
or otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 5.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee, any Holder of any Security with
respect to the Securities of the related Series or any holder of any Capital
Security to exercise any right or remedy accruing upon any Event of Default with
respect to the Securities of the related series 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 and the right and remedy given to the holders of Capital Securities
by Section 5.8 may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee, the Holders or the holders of Capital Securities, as
the case may be.

     Section 5.12. Control by Holders.

     The Holders of not less than a majority in aggregate 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 that
is not inconsistent with such direction, and

     (3) subject to the provisions of Section 6.1, the Trustee shall have the
right to decline to follow such direction if a Responsible Officer or Officers
of the Trustee shall, in good faith, 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.

     Section 5.13. Waiver of Past Defaults.

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Securities of any series affected thereby and, in the case of
any Securities of a series initially issued to an Issuer Trust, the holders of a
majority in aggregate Liquidation Amount (as defined in the related Trust
Agreement) of the Capital Securities issued by such Issuer Trust may waive any
past default hereunder and its consequences with respect to such series 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 (unless such
default has been cured and the Corporation has paid to or deposited with the
Trustee a sum sufficient to pay all matured installments of interest (including
any Additional Interest) and all principal of (and premium, if any, on) all
Securities of that series due otherwise than by acceleration), or

                                      -43-
<PAGE>
 
     (2) in respect of a covenant or provision hereof that under Article IX
cannot be modified or amended without the consent of each Holder of any
Outstanding Security of such series affected.

     Any such waiver shall be deemed to be on behalf of the Holders of all the
Securities of such series or, in the case of a waiver by holders of Capital
Securities issued by such Issuer Trust, by all holders of Capital Securities
issued by such Issuer Trust.

     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,
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 of Holders, holding in
the aggregate more than 10% in aggregate 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 Usury, Stay or Extension Laws.

     The Corporation 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 Corporation (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 6.1. Certain Duties and Responsibilities.

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

                                      -44-
<PAGE>
 
     (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 that 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.

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

     (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

     (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 a 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 6.2. 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, 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

                                      -45-
<PAGE>
 
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 5.1(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 that is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

     Section 6.3. Certain Rights of Trustee.

     Subject to the provisions of Section 6.1:

     (a) the Trustee may rely and shall be protected in acting or refraining

other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

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

liabilities that 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 Corporation,
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.

     Section 6.4. 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
Corporation, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Corporation of the Securities or the proceeds thereof.

     Section 6.5. May Hold Securities.

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

     Section 6.6. 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 Corporation.

     Section 6.7. Compensation and Reimbursement.

     The Corporation 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 Corporation 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 negligence or bad faith;
and

     (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability 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
Indenture.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or 5.1(5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

     Section 6.8. Disqualification; Conflicting Interests.

     (a) The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act. Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of said Section 310(b).

     (b) The Trust Agreement and the Guarantee Agreement with respect to each
Issuer Trust shall be deemed to be specifically described in this Indenture for
the purposes of clause (i) of the first proviso contained in Section 310(b) of
the Trust Indenture Act.

     Section 6.9. 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 or 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 purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Corporation nor any Person directly or indirectly
controlling, controlled by or under common control with the Corporation 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 Corporation. 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 any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

                                      -48-
<PAGE>
 
     (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 aggregate principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Corporation.

     (d) If at any time:

     (1) the Trustee shall fail to comply with Section 6.8 after written request
therefor by the Corporation 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 6.9 and shall fail
to resign after written request therefor by the Corporation 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 Corporation, acting pursuant to the authority of
a Board Resolution, may remove the Trustee with respect to the Securities of all
series issued hereunder, 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
such Holder and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to the Securities of
all series issued hereunder and the appointment of a successor Trustee or
Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause with respect
to the Securities of one or more series, the Corporation, 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 aggregate principal amount of the Outstanding Securities of
such series delivered to the Corporation 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 Corporation. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Corporation or the Holders and accepted appointment in the
manner hereinafter provided, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, subject to Section 5.14, on
behalf of such Holder 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 Corporation 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 Corporation 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 Corporation 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 Corporation,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees 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 Corporation 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 Corporation 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

                                      -50-
<PAGE>
 
Trustee shall be a party, or any corporation succeeding to all or substantially
all of the corporate trust business of the Trustee, shall be the successor of
the Trustee hereunder, provided such corporation shall be otherwise qualified
and eligible under this Article, without the 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 Corporation.

     If and when the Trustee shall be or become a creditor of the Corporation
(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 Corporation (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 or
pursuant to Section 3.6, 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
Corporation 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 or Territory
thereof 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 Corporation. The Trustee may at any time
terminate the agency of an Authenticating Agent

                                      -51-
<PAGE>
 
by giving written notice thereof to such Authenticating Agent and to the
Corporation. 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
Corporation and shall give notice of such appointment in the manner provided in
Section 1.6 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 6.7.

     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 of the series designated therein referred to
in the within mentioned Indenture.

Registrar. The Trustee may destroy any list furnished to it as provided in

     (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 Corporation and the Trustee that neither the Corporation 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 7.3. Reports by Trustee.

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

     Section 7.4. Reports by Corporation.

     The Corporation shall file with the Trustee and with the Commission, and
transmit to Holders, such information, documents and other reports, and such
summaries thereof, as may be required pursuant to the Trust Indenture Act at the

such information, documents or reports required to be filed with the Commission

the Trustee within 15 days after the same is required to be filed with the

Security, the Corporation shall promptly furnish Rule 144A Information, or cause
such information to be furnished, to such Holder or beneficial owner or to a
prospective purchaser of such Security designated by such Holder or beneficial
owner in order to permit compliance by such Holder or beneficial owner with Rule

     Section 8.1. Corporation May Consolidate, Etc., Only on Certain Terms.

     The Corporation shall not consolidate with or merge into any other Person
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
Corporation or convey, transfer or lease its properties and assets substantially
as an entirety to the Corporation, unless:

     (1)  if the Corporation shall consolidate with or merge into another Person
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 Corporation is merged or the Person that acquires by conveyance or
transfer, or that leases, the properties and assets of the Corporation
substantially as an entirety shall be a corporation, partnership or trust
organized and existing under the laws of the United States of America or any
State thereof 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

Indenture on the part of the Corporation to be performed or observed;

                                      -54-

     (2)  immediately after giving effect to such transaction, no Event of
Default, and no event that, after notice or lapse of time, or both, would
constitute an Event of Default, shall have happened and be continuing; and

     (3)  the Corporation 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 comply 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
6.1, may rely upon such Officers' Certificate and Opinion of Counsel as
conclusive evidence that such transaction complies with this Section 8.1.

     Section 8.2. Successor Corporation Substituted.

     Upon any consolidation or merger by the Corporation with or into any other
Person, or any conveyance, transfer or lease by the Corporation of its
properties and assets substantially as an entirety to any Person in accordance
with Section 8.1, the successor corporation formed by such consolidation or into
which the Corporation 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 Corporation under this Indenture with the same effect as if
such successor Person had been named as the Corporation herein; and in the event
of any such conveyance, transfer or lease the Corporation shall be discharged
from all obligations and covenants under the Indenture and the Securities.

     Such successor Person may cause to be executed, and may issue either in its
own name or in the name of the Corporation, any or all of the Securities
issuable hereunder that theretofore shall not have been signed by the
Corporation and delivered to the Trustee; and, upon the order of such successor
Person instead of the Corporation and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Securities that previously shall have been signed and
delivered by the officers of the Corporation to the Trustee for authentication
pursuant to such provisions and any Securities that such successor Person
thereafter shall cause to be executed 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.

     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.

     for the benefit of less than all series of Securities, stating that such
     covenants are expressly being included solely for the benefit of the series
     specified) or to surrender any right or power herein conferred upon the
     Corporation; or

          (5)  to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events

     only when there is no Security Outstanding of any series created prior to
     the execution of such supplemental indenture that is entitled to the
     benefit of such provision or (b) not apply to any Outstanding Securities;
     or

     herein that may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture, provided that such action pursuant
     to this clause (7) shall not adversely affect the interest of the Holders
     of Securities of any series in any material respect or, in the case of the
     Securities of a series issued to an Issuer Trust and for so long as any of
     the corresponding series of Capital Securities issued by such Issuer Trust

and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights 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 of each series affected
thereby,

     (1)  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 any premium payable
upon the redemption thereof, or reduce the amount of principal of a Discount
Security that would be due and payable upon a declaration of acceleration of the
Maturity thereof pursuant to Section 5.2, 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 Redemption Date), or

     (2)  reduce the percentage in aggregate 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
10.5, 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;

provided, further, that, in the case of the Securities of a series issued to an
Issuer Trust, so long as any of the corresponding series of Capital Securities
issued by such Issuer Trust remains outstanding, (i) no such amendment shall be
made that adversely affects the holders of such Capital Securities in any
material respect, 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 Amount (as defined in the related
Trust Agreement) of such Capital Securities then outstanding unless and until
the principal of (and premium, if any, on) the Securities of such series and all
accrued and (subject to Section 3.8) unpaid interest (including any Additional
Interest) thereon have been paid in full, and (ii) no amendment shall be made to
Section 5.8 of this Indenture that would impair the rights of the holders of
Capital Securities issued by any Issuer Trust provided therein without the prior
consent of the holders of each such Capital Security then outstanding unless and
until the principal of (and premium, if any, on) the Securities of such series
and all accrued and (subject to Section 3.8) 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 any corresponding
series of Capital Securities of an Issuer Trust that holds the Securities of any
series, or that modifies the rights of the Holders of Securities of such series
or holders of such Capital Securities of such corresponding 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 or holders
of Capital Securities of any other such corresponding 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 9.3. Execution of Supplemental Indentures.

     In executing or accepting the additional trusts created by any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 6.1) 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 herein provided for relating to such action have been
complied with. The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture that affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

     Section 9.4. 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

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

                                   Covenants

     Section 10.1. Payment of Principal, Premium and Interest.

     The Corporation 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 (including any Additional Interest) on the Securities of
that series in accordance with the terms of such Securities and this Indenture.

     Section 10.2. Maintenance of Office or Agency.

     The Corporation 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 Corporation in respect of the Securities of that series and this
Indenture may be served. The Corporation initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The
Corporation 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 Corporation 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 Corporation
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

     The Corporation 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 Corporation of its obligation to maintain an office or agency in
each Place of Payment for Securities of any series for such purposes. The
Corporation 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 10.3. Money for Security Payments to be Held in Trust.

     If the Corporation 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, an) 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 Corporation shall have one or more Paying Agents, it will,
prior to 10:00 a.m., New York City time, on each due date of the principal of
(or premium, if any) or interest (including any Additional Interest) on any
Securities, deposit with a Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest (including any Additional 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 (including any
Additional Interest), and (unless such Paying Agent is the Trustee) the
Corporation will promptly notify the Trustee of its failure so to act.

     The Corporation 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 (including any Additional Interest) on the
     Securities of a 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;

                                      -59-
<PAGE>
 
          (2)  give the Trustee notice of any default by the Corporation (or any
     other obligor upon such Securities) in the making of any payment of
     principal (and premium, if any) or interest (including any Additional
     Interest) in respect of any Security of any Series;

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

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

     The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Corporation Order direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Corporation 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
Corporation 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 Corporation in trust for the payment of the principal of (and premium, if
any) or interest (including any Additional 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 Corporation Request to the Corporation, or (if then held by the
Corporation) 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 Corporation for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Corporation 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 Corporation 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 to the Corporation.

     Section 10.4. Statement as to Compliance.

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

     Section 10.5. Waiver of Certain Covenants.

     Subject to the rights of holders of Capital Securities specified in Section
9.2, if any, the Corporation may omit in any particular instance to comply with
any covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4)
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 aggregate 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 Corporation in respect of
any such covenant or condition shall remain in full force and effect.

     Section 10.6. Additional Sums.

     In the case of the Securities of a series initially issued to an Issuer
Trust, so long as no Event of Default has occurred and is continuing and except
as otherwise specified as contemplated by Section 2.1 or Section 3.1, if (i) an
Issuer Trust is the Holder of all of the Outstanding Securities of such series,
and (ii) a Tax Event has occurred and is continuing in respect of such Issuer
Trust, the Corporation shall pay to such Issuer Trust (and its permitted
successors or assigns under the related Trust Agreement) for so long as such
Issuer Trust (or its permitted successor or assignee) is the registered holder
of the Outstanding Securities of such series, such additional sums as may be
necessary in order that the amount of Distributions (including any Additional
Amounts (as defined in such Trust Agreement)) then due and payable by such
Issuer Trust on the related Capital 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 arising from such Tax Event;
provided, however, that Additional Sums shall not include any withholding taxes
arising after the occurrence of a Tax Event and which have been withheld from
payments to Holders of Trust Securities and for which Holders are liable (the
"Additional Sums"). 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 deferral of the payment
of interest pursuant to Section 3.12 or the Securities shall not defer the
payment of any Additional Sums that may be due and payable.

     Section 10.7. Additional Covenants.

     The Corporation covenants and agrees with each Holder of Securities of each
series that it shall not (x) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Corporation that rank pari passu in all respects with or junior in interest to
the Securities of such series, or (y) declare or pay any dividends or
distributions on, or redeem purchase, acquire or make a liquidation payment with
respect to, any shares of the Corporation's capital stock (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Corporation in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants, in connection with

                                      -61-
<PAGE>
 
a dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Corporation (or securities convertible into
or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a Subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any Rights Plan, or the issuance of
rights, stock or other property under any Rights Plan, or the redemption or
repurchase of rights pursuant thereto, or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock) if at such time (i) there shall have occurred any event (A) of which
the Corporation has actual knowledge that with the giving of notice or the lapse
of time, or both, would constitute an Event of Default with respect to the
Securities of such series, and (B) which the Corporation shall not have taken
reasonable steps to cure, (ii) if the Securities of such series are held by an
Issuer Trust, the Corporation shall be in default with respect to its payment of
any obligations under the Guarantee Agreement relating to the Capital Securities
issued by such Issuer Trust, or (iii) the Corporation shall have given notice of
its election to begin an Extension Period with respect to the Securities of such
series as provided herein and shall not have rescinded such notice, or such
Extension Period, or any extension thereof, shall be continuing.

     The Corporation also covenants with each Holder of Securities of a series
issued to an Issuer Trust (i) to hold, directly or indirectly, 100% of the
Common Securities of such Issuer Trust, provided that any permitted successor of
the Corporation hereunder may succeed to the Corporation's ownership of such
Common Securities, (ii) as holder of such Common Securities, not to voluntarily
terminate, wind-up or liquidate such Issuer Trust, other than (a) in connection
with a distribution of the Securities of such series to the holders of the
related Capital Securities in liquidation of such Issuer Trust, or (b) in
connection with certain mergers, consolidations or amalgamations 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 Issuer
Trust to continue not to be taxable as a corporation for United States federal
income tax purposes.

     Section 10.8.   Original Issue Discount.

     For each year during which any Securities that were issued with original
issue discount are Outstanding, the Corporation shall furnish to each Paying
Agent in a timely fashion such information as may be reasonably requested by
each Paying Agent in order that each Paying Agent may prepare the information
which it is required to report for such year on Internal Revenue Service Forms
1096 and 1099 pursuant to Section 6049 of the Internal Revenue Code of 1986, as
amended.  Such information shall include the amount of original issue discount
includible in income for each $1,000 of principal amount at Stated Maturity of
outstanding Securities during such year.

                           Redemption of Securities

     Section 11.1 Applicability of This Article.

     Redemption of Securities of any series (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 of a series shall be
subject to partial redemption only in the amount of $1,000 or any integral
multiples thereof.

     Section 11.2. Election to Redeem; Notice to Trustee.

     The election of the Corporation to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Corporation, the Corporation shall, at least 45 days prior to the
Redemption Date (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee and, in the case of Securities of a series held by an Issuer
Trust, the Property Trustee under the related Trust Agreement, of such date and
of the principal amount of Securities of the applicable series to be redeemed
and provide the additional information required to be included in the notice or
notices contemplated by Section 11.4; provided that in the case of any series of
Securities initially issued to an Issuer Trust, for so long as such Securities
are held by such Issuer Trust, such notice shall be given not less than 45 nor
more than 75 days prior to such Redemption Date (unless a shorter notice shall
be satisfactory to the Property Trustee under the related Trust Agreement). 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
Corporation shall furnish the Trustee with an Officers' Certificate and an
Opinion of Counsel evidencing compliance with such restriction.

     Section 11.3. Selection of Securities to be Redeemed.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of 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 promptly notify the Corporation 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 that has been or is to be
redeemed.

     Section 11.4. 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 Redemption Date, to each Holder of Securities to be redeemed, at
the address of such Holder as it appears in the Securities Register, provided
that in the case of any series of Securities initially issued to an Issuer
Trust, for so long as such Securities are held by such Issuer Trust, such notice
shall be given not less than 45 nor more than 75 days prior to such Redemption
Date (unless a shorter notice shall be satisfactory to the Property Trustee
under the related Trust Agreement).

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

     (a) the Redemption Date;

     (b) the Redemption Price or, if the Redemption Price cannot be calculated
prior to the time the notice is required to be sent, the estimate of the
Redemption Price together with a statement that it is an estimate and that the
actual Redemption Price will be calculated on the third Business Day prior to
the Redemption Date (and if an estimate is provided, a further notice shall be
sent of the actual Redemption Price on the date that such Redemption Price is
calculated);

     (c) if less than all Outstanding Securities of such particular series 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 Redemption Date, the Redemption Price will become due and
payable upon each such Security or portion thereof, and that interest (including
any Additional 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;

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

     (g) such other provisions as may be required in respect of the terms of a
particular series of Securities.

     Notice of redemption of Securities to be redeemed at the election of the
Corporation shall be given by the Corporation or, at the Corporation's request,
by the Trustee in the name and at the expense of the Corporation and shall be
irrevocable. The notice if mailed in the manner provided above 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 11.5. Deposit of Redemption Price.

     Prior to 10:00 a.m., New York City time, on the Redemption Date specified
in the notice of redemption given as provided in Section 11.4, the Corporation
will deposit with the Trustee or with one or more Paying Agents (or if the
Corporation is acting as its own Paying Agent, the Corporation will segregate
and hold in trust as provided in Section 10.3) an amount of money sufficient to
pay the Redemption Price of, and any accrued interest (including any Additional
Interest) on, all the Securities (or portions thereof) that are to be redeemed
on that date.

     Section 11.6. Payment of Securities Called for Redemption.

     If any notice of redemption has been given as provided in Section 11.4, 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, together with accrued
interest (including any Additional Interest) to the Redemption Date. 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 Corporation at the applicable Redemption Price,
together with accrued interest (including any Additional Interest) to the
Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest (including any Additional
Interest) whose Stated Maturity is on or prior to the Redemption Date will 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 3.8.

     Upon presentation of any Security redeemed in part only, the Corporation
shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Corporation, 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 any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal of and premium, if any, on such Security
shall, until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

     Section 11.7. Right of Redemption of Securities Initially Issued to an
Issuer Trust.

     In the case of the Securities of a series initially issued to an Issuer
Trust, except as otherwise specified as contemplated by Section 3.1, the
Corporation, at its option, may redeem such Securities (i) on or after the date
specified in such Security, in whole at any time or in part from time to time,
or (ii) upon the occurrence and during the continuation of a Tax Event, an
Investment Company Event or a Capital Treatment Event, at any time within 90
days following the occurrence and during the continuation of such Tax Event,
Investment Company Event or Capital Treatment Event, in whole (but not in part),
in each case at a Redemption Price specified in such Security, together with
accrued interest (including any Additional Interest) to, but excluding, the
Redemption Date.

     If less than all the Securities of any such series are to be redeemed, the
aggregate principal amount of such Securities remaining Outstanding after giving
effect to such redemption shall be sufficient to satisfy any provisions of the
Trust Agreement related to the Issuer Trust to which such Securities were

                                      -65-

issued, including any requirement in such Trust Agreement as to the minimum
Liquidation Amount (as defined in such Trust Agreement) of Capital Securities
that may be held by a holder of Capital Securities thereunder.


                                  ARTICLE XII

                                 Sinking Funds

     Section 12.1. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any sinking fund payment in excess of such minimum amount that is
permitted to be made by the terms of such Securities of any series is herein
referred to as an "optional sinking fund payment". If provided for by the terms
of any Securities of any series, the cash amount of any sinking fund payment may
be subject to reduction as provided in Section 12.2. Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of such Securities.

     Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

     In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Securities of a series in cash, the Corporation may at its
option, at any time no more than 16 months and no less than 45 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series (together with the unmatured coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Corporation, except Securities of such series that have been redeemed through
the application of mandatory or optional sinking fund payments pursuant to the
terms of the Securities of such series, accompanied by a Corporation Order
instructing the Trustee to credit such obligations and stating that the
Securities of such series were originally issued by the Corporation by way of
bona fide sale or other negotiation for value; provided that the Securities to
be so credited have not been previously so credited. The Securities to be so
credited shall be received and credited for such purpose by the Trustee at the
redemption price for such Securities, as specified in the Securities so to be
redeemed, for redemption through operation of the sinking fund and the amount of
such sinking fund payment shall be reduced accordingly.

     Section 12.3. Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Corporation will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, that is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered. Such Officers' Certificate shall be
irrevocable and upon its

                                      -66-
<PAGE>
 
delivery the Corporation shall be obligated to make the cash payment or payments
therein referred to, if any, on or before the succeeding sinking fund payment
date. In the case of the failure of the Corporation to deliver such Officers'
Certificate (or, as required by this Indenture, the Securities and coupons, if
any, specified in such Officers' Certificate) by the due date therefor, the
sinking fund payment due on the succeeding sinking fund payment date for such
series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of the Securities of such series subject to a mandatory sinking
fund payment without the right to deliver or credit securities as provided in
Section 12.2 and without the right to make the optional sinking fund payment
with respect to such series at such time.

     Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made with respect
to the Securities of any particular series shall be applied by the Trustee (or
by the Corporation if the Corporation is acting as its own Paying Agent) on the
sinking fund payment date on which such payment is made (or, if such payment is
made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Corporation is acting as its own Paying Agent, segregated
and held in trust by the Corporation as provided in Section 10.3) for such
series and together with such payment (or such amount so segregated) shall be
applied in accordance with the provisions of this Section 12.3. Any and all
sinking fund moneys with respect to the Securities of any particular series held
by the Trustee (or if the Corporation is acting as its own Paying Agent,
segregated and held in trust as provided in Section 10.3) on the last sinking
fund payment date with respect to Securities of such series and not held for the
payment or redemption of particular Securities of such series shall be applied
by the Trustee (or by the Corporation if the Corporation is acting as its own
Paying Agent), together with other moneys, if necessary, to be deposited (or
segregated) sufficient for the purpose, to the payment of the principal of the
Securities of such series at Maturity. The Trustee shall select the Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 11.3 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Corporation in the manner provided in Section 11.4.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Section 11.6. On or before each
sinking fund payment date, the Corporation shall pay to the Trustee (or, if the
Corporation is acting as its own Paying Agent, the Corporation shall segregate
and hold in trust as provided in Section 10.3) in cash a sum in the currency in
which Securities of such series are payable (except as provided pursuant to
Section 3.1) equal to the principal (and premium, if any) and any interest
(including any Additional Interest) accrued to the Redemption Date for
Securities or portions thereof to be redeemed on such sinking fund payment date
pursuant to this Section 12.3.

     Neither the Trustee nor the Corporation shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Corporation, if the
Corporation is then acting as its own Paying Agent) shall redeem such Securities
if cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Corporation) for that purpose in accordance with the terms of
this Article XII. Except as aforesaid, any moneys in the sinking fund for

                                      -67-
<PAGE>
 
such series at the time when any such default or Event of Default shall occur
and any moneys thereafter paid into such sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of the Securities and coupons, if any, of such series; provided,
however, that in case such default or Event of Default shall have been cured or
waived herein, such moneys shall thereafter be applied on the next sinking fund
payment date for the Securities of such series on which such moneys may be
applied pursuant to the provisions of this Section 12.3.


                                  ARTICLE XIII

                          Subordination of Securities

     Section 13.1. Securities Subordinate to Senior Indebtedness.

     The Corporation 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 of each and every series are hereby expressly
made subordinate and subject in right of payment to the prior payment in full of
all Senior Indebtedness.

     Section 13.2. No Payment When Senior Indebtedness in Default; Payment Over
of Proceeds Upon Dissolution, Etc.

     If the Corporation shall default in the payment of any principal of (or
premium, if any) or interest on any Senior Indebtedness when the same becomes
due and payable, whether at maturity or at a date fixed for prepayment or by
declaration of acceleration or otherwise, then, upon written notice of such
default to the Corporation by the holders of Senior Indebtedness or any trustee
therefor, unless and until such default shall have been cured or waived or shall
have ceased to exist, no direct or indirect payment (in cash, property,
securities, by set-off or otherwise) shall be made or agreed to be made on
account of the principal of (or premium, if any) or interest (including any
Additional Interest) on any of the Securities, or in respect of any redemption,
repayment, retirement, purchase or other acquisition of any of the Securities.

     In the event of (a) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceedings relating
to the Corporation, its creditors or its property, (b) any proceeding for the
liquidation, dissolution or other winding up of the Corporation, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings, (c)
any assignment by the Corporation for the benefit of creditors or (d) any other
marshalling of the assets of the Corporation (each such event, if any, herein
sometimes referred to as a "Proceeding"), all Senior Indebtedness (including any
interest thereon accruing after the commencement of any such proceedings) shall
first be paid in full before any payment or distribution, whether in cash,
securities or other property, shall be made to any Holder of any of the
Securities on account thereof. Any payment or distribution, whether in cash,
securities or other property (other than securities of the Corporation or any
other corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Securities, to the payment of all Senior Indebtedness at the time outstanding
and to any securities issued in respect thereof under any such plan of
reorganization or readjustment), which would otherwise

                                      -68-
<PAGE>
 
(but for these subordination provisions) be payable or deliverable in respect of
the Securities of any series shall be paid or delivered directly to the holders
of Senior Indebtedness in accordance with the priorities then existing among
such holders until all Senior Indebtedness (including any interest thereon
accruing after the commencement of any Proceeding) shall have been paid in full.

     In the event of any Proceeding, after payment in full of all sums owing
with respect to Senior Indebtedness, the Holders of the Securities, together
with the holders of any obligations of the Corporation ranking on a parity with
the Securities, shall be entitled to be paid from the remaining assets of the
Corporation the amounts at the time due and owing on account of unpaid principal
of (and premium, if any) and interest on the Securities and such other
obligations before any payment or other distribution, whether in cash, property
or otherwise, shall be made on account of any capital stock or any obligations
of the Corporation ranking junior to the Securities and such other obligations.
If, notwithstanding the foregoing, any payment or distribution of any character
or any security, whether in cash, securities or other property (other than
securities of the Corporation or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the
indebtedness evidenced by the Securities, to the payment of all Senior
Indebtedness at the time outstanding and to any securities issued in respect
thereof under any such plan of reorganization or readjustment), shall be
received by the Trustee or any Holder in contravention of any of the terms
hereof and before all Senior Indebtedness shall have been paid in full, such
payment or distribution or security shall be received in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of the
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness in full. In the event of the failure of the Trustee or any Holder
to endorse or assign any such payment, distribution or security, each holder of
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the
same.

     The Trustee and the Holders shall take such action (including, without
limitation, the delivery of this Indenture to an agent for the holders of Senior
Indebtedness or consent to the filing of a financing statement with respect
hereto) as may, in the opinion of counsel designated by the holders of a
majority in principal amount of the Senior Indebtedness at the time outstanding,
be necessary or appropriate to assure the effectiveness of the subordination
effected by these provisions.

     The provisions of this Section 13.2 shall not impair any rights, interests,
remedies or powers of any secured creditor of the Corporation in respect of any
security interest the creation of which is not prohibited by the provisions of
this Indenture.

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

     Section 13.3. 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 Corporation, at any time, except during
the pendency of the conditions described in the first paragraph of Section 13.2
or of any Proceeding referred to in Section 13.2, from making payments

                                      -69-
<PAGE>
 
at any time of principal of (and premium, if any) or interest (including any
Additional Interest) on the Securities, or (b) the application by the Trustee of
any moneys 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 13.4. 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 Corporation that by its express terms is subordinated
to Senior Indebtedness of the Corporation 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 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 interest (including any Additional Interest) on the
Securities shall be paid in full. For purposes of such subrogation, 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 Corporation,
its creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Corporation to or
on account of the Senior Indebtedness.

     Section 13.5. 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 Indebtedness 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 Corporation and the Holders of the
Securities, the obligations of the Corporation, 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 Corporation of the
Holders of the Securities and creditors of the Corporation other than their
rights in relation to the holders of Senior Indebtedness; or (c) prevent the
Trustee or the Holder of any Security (or to the extent expressly provided
herein, the holder of any Capital Security) from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture,
including 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.

<PAGE>
 
     Section 13.6. 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 in this
Article and appoints the Trustee his or her attorney-in-fact for any and all
such purposes.

     Section 13.7. 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
Corporation or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Corporation 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.

     Without in any way limiting the generality of the immediately preceding
paragraph, the holders of Senior Indebtedness may, at any time and from to time,
without the consent of or notice to the Trustee or the Holders of the Securities
of any series, 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 Corporation and any other Person.

     Section 13.8. Notice to Trustee.

     The Corporation shall give prompt written notice to the Trustee of any fact
known to the Corporation that 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 that 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
Corporation or a holder of Senior Indebtedness or from any trustee, agent or
representative therefor; 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, the payment of the principal of (and premium, if
any, on) 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 that may be received by it within two Business Days prior to
such date.

     Subject to the provisions of Section 6.1, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
or herself to be a holder of Senior Indebtedness

                                      -71-
<PAGE>
 
(or a trustee or attorney-in-fact therefor) to establish that such notice has
been given by a holder of Senior Indebtedness (or a trustee or attorney-in-fact
therefor). 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 13.9. Reliance on Judicial Order or Certificate of Liquidating
Agent.

     Upon any payment or distribution of assets of the Corporation referred to
in this Article, the Trustee, subject to the provisions of Section 6.1, 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 Corporation, 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 13.10. 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 Corporation 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 13.11. Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness that may at
any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

     Section 13.12. Article Applicable to Paying Agents.

     If at any time any Paying Agent other than the Trustee shall have been
appointed by the Corporation 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.

          institutional buyer; and

               (B)  the Owner and any person acting on its behalf have taken

               person acting on its behalf reasonably believed that the
               Transferee was outside the United States, or

                    (ii)   the transaction is being executed in, on or through
               the facilities of the Eurobond market, as regulated by the
               Association of International Bond Dealers, or another designated
               offshore securities market and neither the Owner nor any person
               acting on its behalf knows that the transaction has been

Agreement, (ii) sell, assign, transfer, exchange, mortgage, pledge, set-off or
otherwise dispose of any of the Trust Property or interests therein, including

any of the Trust Property adverse to the interest of the Issuer Trust or the
Holders in their capacity as Holders.

     (c) In connection with the issue and sale of the Capital Securities, the
Depositor shall have the right and responsibility to assist the Issuer Trust
with respect to, or effect on behalf of the Issuer Trust, the following (and any
actions taken by the Depositor in furtherance of the following prior to the date
of this Trust Agreement are hereby ratified and confirmed in all respects):

                                       16
<PAGE>
 
          (i) the preparation by the Issuer Trust of an Offering Circular in
     relation to the Capital Securities, including any amendments thereto and
     the taking of any action necessary or desirable to sell the Capital
     Securities in a transaction or a series of transactions exempt from the
     registration requirements of the Securities Act of 1933, as amended;

          (ii) the determination of the States in which to take appropriate
     action to qualify or register for sale all or part of the Capital
     Securities and the determination of any and all such acts, other than
     actions that must be taken by or on behalf of the Issuer Trust, and the
     advice to the Issuer Trust of actions they must take on behalf of the
     Issuer Trust, and the preparation for execution and filing of any documents
     to be executed and filed by the Issuer Trust or on behalf of the Issuer
     Trust, as the Depositor deems necessary or advisable in order to comply
     with the applicable laws of any such States in connection with the sale of
     the Capital Securities;

          (iii) the negotiation of the terms of, and the execution and delivery
     of, the Purchase Agreement providing for the sale of the Capital
     Securities; and

          (iv) the taking of any other actions necessary or desirable to carry
     out any of the foregoing activities.

     (d) Notwithstanding anything herein to the contrary, the Administrators and
the Issuer Trustees are authorized and directed to conduct the affairs of the
Issuer Trust and to operate the Issuer Trust so that the Issuer Trust will not
be deemed to be an "investment company" required to be registered under the
Investment Company Act, and will not be taxable as a corporation or classified
as other than a grantor trust for United States Federal income tax purposes and
so that the Debentures will be treated as indebtedness of the Depositor for
United States Federal income tax purposes. In this connection, each
Administrator, the Property Trustee and the Holders of at least a Majority in
Liquidation Amount of the Common Securities are authorized to take any action,
not inconsistent with applicable law, the Certificate of Trust or this Trust
Agreement, that such Administrator, the Property Trustee or Holders of Common
Securities determine in their discretion to be necessary or desirable for such
purposes, as long as such action does not adversely affect in any material
respect the interests of the Holders of the Outstanding Capital Securities. In
no event shall the Administrators or the Issuer Trustees be liable to the Issuer
Trust or the Holders for any failure to comply with this section that results
from a change in law or regulation or in the interpretation thereof.

     Section 2.8.  Assets of Trust.

     The assets of the Issuer Trust shall consist of the Trust Property.

     Section 2.9.  Title to Trust Property.

     Legal title to all Trust Property shall be vested at all times in the
Property Trustee (in its capacity as such) and shall be held and administered by
the Property Trustee in trust for the benefit of the Issuer Trust and the
Holders in accordance with this Trust Agreement.


                                  ARTICLE III.

                                Payment Account

     Section 3.1.  Payment Account.

     (a) On or prior to the Closing Date, the Property Trustee shall establish
the Payment Account. The Property Trustee and its agents shall have exclusive
control and sole right of withdrawal with respect to the Payment Account for the
purpose of making deposits in and withdrawals from the Payment Account in
accordance with this Trust Agreement. All monies and other property deposited or
held from time to time in the Payment Account shall be held by the Property
Trustee in the Payment Account for the exclusive benefit of the Holders and for
distribution as herein provided, including (and subject to) any priority of
payments provided for herein.

     (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other
payments or proceeds with respect to, the Debentures. Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.


                                  ARTICLE IV.

                           Distributions; Redemption

     Section 4.1.  Distributions.

     (a) The Trust Securities represent undivided beneficial interests in the
Trust Property, and Distributions (including of Additional Amounts) will be made
on the Trust Securities at the rate and on the dates that payments of interest
(including of Additional Interest, as defined in the Indenture) are made on the
Debentures. Accordingly:

          (i) Distributions on the Issuer Trust Securities shall be cumulative,
     and will accumulate whether or not there are funds of the Trust available
     for the payment of Distributions. Distributions shall accumulate from
     December 20, 1996, and, except in the event (and to the extent) that the
     Depositor exercises its right to defer the payment

                                       18
<PAGE>
 
     of interest on the Debentures pursuant to the Indenture, shall be payable
     semi-annually in arrears on June 30 and December 30 of each year,
     commencing on June 30, 1997. If any date on which a Distribution is
     otherwise payable on the Trust Securities is not a Business Day, then the
     payment of such Distribution shall be made on the next succeeding day that
     is a Business Day (and without any interest or other payment in respect of
     any such delay), with the same force and effect as if made on the date on
     which such payment was originally payable (each date on which distributions
     are payable in accordance with this Section 4.1(a), a "Distribution Date").

          (ii) The Trust Securities shall be entitled to Distributions payable
     at a rate of 7.94% per annum of the Liquidation Amount of the Trust
     Securities. The amount of Distributions payable for any period less than a
     full Distribution period shall be computed on the basis of a 360-day year
     of twelve 30-day months and the actual number of days elapsed in a partial
     month in a period. Distributions payable for each full Distribution period
     will be computed by dividing the rate per annum by two. The amount of
     Distributions payable for any period shall include any Additional Amounts
     in respect of such period.

          (iii)  Distributions on the Trust Securities shall be made by the
     Property Trustee from the Payment Account and shall be payable on each
     Distribution Date only to the extent that the Issuer Trust has funds then
     on hand and available in the Payment Account for the payment of such
     Distributions.

     (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date, which shall be at the close of business on the fifteenth day
(whether or not a Business Day) next preceding the relevant Distribution Date.

     Section 4.2.  Redemption.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Issuer Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

     (b) Notice of redemption shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior
to the Redemption Date to each Holder of Trust Securities to be redeemed, at
such Holder's address appearing in the Security Register. All notices of
redemption shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price or if the Redemption Price cannot be
     calculated prior to the time the notice is required to be sent, the
     estimate of the Redemption Price

                                       19
<PAGE>
 
     together with a statement that it is an estimate and that the actual
     Redemption Price will be calculated on the third Business Day prior to the
     Redemption Date (and if an estimate is provided, a further notice shall be
     sent of the actual Redemption Price on the date that such Redemption Price
     is calculated);

          (iii) the CUSIP number or CUSIP numbers of the Capital Securities
     affected;

          (iv) if less than all the Outstanding Trust Securities are to be
     redeemed, the identification and the aggregate Liquidation Amount of the
     particular Trust Securities to be redeemed;

          (v) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Trust Security to be redeemed and that
     Distributions thereon will cease to accumulate on and after said date,
     except as provided in Section 4.2(d) below; and

          (vi) the place or places where the Trust Securities are to be
     surrendered for the payment of the Redemption Price.

     The Trust in issuing the Trust Securities may use "CUSIP" or "private
placement" numbers (if then generally in use), and, if so, the Property Trustee
shall indicate the "CUSIP" or "private placement" numbers of the Trust
Securities in notices of redemption and related materials 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 Trust Securities
or as contained in any notice of redemption and related materials.

     (c) The Trust Securities redeemed on each Redemption Date shall be redeemed
at the Redemption Price with the proceeds from the contemporaneous redemption of
Debentures. Redemptions of the Trust Securities shall be made and the Redemption
Price shall be payable on each Redemption Date only to the extent that the
Issuer Trust has funds then on hand and available in the Payment Account for the
payment of such Redemption Price.

     (d) If the Property Trustee gives a notice of redemption in respect of any
Capital Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, with respect to
Book-Entry Capital Securities, irrevocably deposit with the Clearing Agency for
such Book-Entry Capital Securities, to the extent available therefor, funds
sufficient to pay the applicable Redemption Price and will give such Clearing
Agency irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Capital Securities. With respect to Capital Securities that are
not Book-Entry Capital Securities, the Property Trustee, subject to Section
4.2(c), will irrevocably deposit with the Paying Agent, to the extent available
therefor, 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 of the Capital Securities upon surrender of their Capital

                                       20
<PAGE>
 
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
Securities Register for the Trust Securities on the relevant record dates for
the related Distribution Dates. If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights
of Holders holding Trust Securities so called for redemption will cease, except
the right of such Holders to receive the Redemption Price and any Distribution
payable in respect of the Trust Securities on or prior to the Redemption Date,
but without interest, and such Securities will cease to be outstanding. In the
event that any date on which any Redemption Price is payable is not a Business
Day, then payment of the Redemption Price payable on such date will be made on
the next succeeding day that is a Business Day (without any interest or other
payment in respect of any such delay), except that, if such Business Day falls
in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case, with the same force and effect as if made
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 Issuer Trust or by the Depositor pursuant to the
Guarantee Agreement, Distributions on such Trust Securities will continue to
accumulate, as set forth in Section 4.1, from the Redemption Date originally
established by the Issuer 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) Subject to Section 4.3(a), 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 pro
rata to the Common Securities and the Capital Securities based upon the relative
Liquidation Amounts of such classes. The particular Capital Securities to be
redeemed shall be selected on a pro rata basis based upon their respective
Liquidation Amounts not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Capital Securities not previously called
for redemption, provided that so long as the Capital Securities are in book-
entry-only form, such selection shall be made in accordance with the customary
procedures for the Clearing Agency for the Capital Securities, and provided
further that, after giving effect to such redemption, no Holder shall hold
Capital Securities with an aggregate Liquidation Amount of less than $100,000.
The Property Trustee shall promptly notify the Securities Registrar in writing
of the Capital Securities selected for redemption and, in the case of any
Capital Securities selected for partial 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 Capital
Securities shall relate, in the case of any Capital Securities redeemed or to be
redeemed only in part, to the portion of the aggregate Liquidation Amount of
Capital Securities that has been or is to be redeemed.

     Section 4.3.  Subordination of Common Securities.

     (a) Payment of Distributions (including any Additional Amounts) on, the
Redemption Price of, and the Liquidation Distribution in respect of the Trust
Securities, as applicable, shall

                                       21
<PAGE>
 
be made, subject to Section 4.2(e), pro rata among the Common Securities and the
Capital Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date, Redemption Date or
Liquidation Date any Event of Default resulting from a Debenture Event of
Default specified in Section 5.1(1) or 5.1(2) of the Indenture shall have
occurred and be continuing, no payment of any Distribution (including any
Additional Amounts) on, Redemption Price of, or Liquidation Distribution in
respect 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
(including any Additional Amounts) on all Outstanding Capital 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 Capital Securities then called for redemption, or in the case of
payment of the Liquidation Distribution the full amount of such Liquidation
Distribution on all Outstanding Capital 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
any Additional Amounts) on, or the Redemption Price of, the Capital Securities
then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holders of the Common Securities shall have
no 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
Capital Securities have been cured, waived or otherwise eliminated. Until all
such Events of Default under this Trust Agreement with respect to the Capital
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the Holders of the Capital Securities and
not on behalf of the Holders of the Common Securities, and only the Holders of
the Capital Securities will have the right to direct the Property Trustee to act
on their behalf.

     Section 4.4.  Payment Procedures.

     Payments of Distributions (including any Additional Amounts) in respect of
the Capital Securities shall be made by check mailed to the address of the
Person entitled thereto as such address shall appear on the Securities Register
or, if the Capital Securities are held by a Clearing Agency, such Distributions
shall be made to the Clearing Agency in immediately available funds. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Holders of the Common
Securities.

     Section 4.5.  Tax Returns and Reports.

     The Administrators shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Issuer Trust. In this regard, the Administrators shall (a) prepare and file (or
cause to be prepared and filed) all Internal Revenue Service forms required to
be filed in respect of the Issuer Trust in each taxable year of the Issuer
Trust, and

                                       22
<PAGE>
 
(b) prepare and furnish (or cause to be prepared and furnished) to each Holder

willing or able to properly discharge its responsibilities with respect to the
Book-Entry Capital Securities Certificates, and the Property Trustee is unable
to locate a qualified successor, (b) the Issuer Trust at its option advises the
Depositary in writing that it elects to terminate the book-entry system through
the Clearing Agency, (c) a Debenture Event of Default has occurred and is

(b) or (c) above, the Administrators shall notify the Clearing Agency and
instruct the Clearing Agency to notify all Owners of Book-Entry Capital

such event and of the availability of the Definitive Capital Securities
Certificates to Owners of such class or classes, as applicable, requesting the

be issued in an amount representing less than 100 Capital Securities.

     (c) If any Book-Entry Capital Securities Certificate is to be exchanged for
other Capital Securities Certificates or cancelled in part, or if any other

Registrar, whereupon the Property Trustee, in accordance with the Applicable
Procedures, shall instruct the Clearing Agency or its authorized representative
to make a corresponding adjustment to its records. Upon surrender to the
Administrators or the Securities Registrar of the Book-Entry Capital Securities
Certificate or Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrators, or any one of them, shall execute the
Definitive Capital Securities Certificates in accordance with the instructions
of the Clearing Agency; provided, however, that no Definitive Capital Securities
Certificate shall be issued in an amount representing less than 100 Capital
Securities. None of the Securities Registrar, the Issuer Trustees or the
Administrators 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 Capital Securities Certificates,
the Issuer Trustees and Administrators shall recognize the Holders of the
Definitive Capital Securities Certificates as Holders. The Definitive Capital
Securities Certificates shall be printed, lithographed or engraved or may be
produced in any other manner as is reasonably acceptable to the Administrators,
as evidenced by the execution thereof by the Administrators or any one of them.

     (d) Every Capital Securities Certificate executed and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Book-Entry
Capital Securities Certificate or any portion thereof, whether pursuant to this
Article V or Article IV or otherwise, shall be executed and delivered in the
form of, and shall be, a Book-Entry Capital Securities Certificate, unless such
Capital Securities Certificate is registered in the name of a Person other than
the Clearing Agency for such Book-Entry Capital Securities Certificate or a
nominee thereof.

     (e) The Clearing Agency or its nominee, as registered owner of a Book-Entry
Capital Securities Certificate, shall be the Holder of such Book-Entry Capital
Securities Certificate for all purposes under this Agreement and the Book-Entry
Capital Securities Certificate, and Owners with respect to a Book-Entry Capital
Securities Certificate shall hold such interests pursuant to the Applicable
Procedures. The Securities Registrar, the Administrators and the Issuer Trustees
shall be entitled to deal with the Clearing Agency for all purposes of this
Trust Agreement relating to the Book-Entry Capital Securities Certificates
(including the payment of the Liquidation Amount of and Distributions on the
Book-Entry Capital Securities represented thereby and the giving of instructions
or directions by Owners of Book-Entry Capital Securities represented thereby) as
the sole Holder of the Book-Entry Capital Securities represented thereby and
shall have no obligations to the Owners thereof. None of the Property Trustee,
the Administrators nor the Securities Registrar shall have any liability in
respect of any transfers effected by the Clearing Agency.

     The rights of the Owners of the Book-Entry Capital Securities shall be
exercised only through the Clearing Agency and shall be limited to those
established by law, the Applicable Procedures 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 Capital Securities

     Section 5.5.  Registration of Transfer and Exchange of Capital Securities
Certificates; Restricted Capital Securities Legends.

     (a) The Property Trustee shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 5.9, a register or registers for the
purpose of registering Trust Securities Certificates and transfers and exchanges
of Trust Securities Certificates (the "Securities Register") in which the
registrar and transfer agent with respect to the Trust Securities (the
"Securities Registrar"), subject to such reasonable regulations as it may
prescribe, shall provide for the registration of Capital Securities Certificates
and Common Securities Certificates (subject to Section 5.11 in the case of the
Common Securities Certificates) and registration of transfers and exchanges of
Capital Securities Certificates as herein provided. The Person acting as the
Property Trustee shall at all times also be the Securities Registrar.

     Upon surrender for registration of transfer of any Capital Securities
Certificate at the office or agency maintained pursuant to Section 5.9, the
Administrators or any one of them shall execute and deliver to the Property
Trustee, and the Property Trustee shall deliver, in the name of the designated
transferee or transferees, one or more new Capital Securities Certificates in
authorized denominations of a like aggregate Liquidation Amount dated the date
of execution by such Administrator; provided that no Holder may transfer any
Capital Security if giving effect to such transfer would cause any Holder to
hold less than $100,000 aggregate Liquidation Amount of Capital Securities. Any
purported transfer prohibited by the preceding proviso shall be null and void
and of no force or effect and the purported transferee of the affected Capital
Securities shall be deemed to have no interest whatsoever in such Capital
Securities.

     The Securities Registrar shall not be required, (i) to issue, register the
transfer of or exchange any Capital Security during a period beginning at the
opening of business 15 days before the day of selection for redemption of such
Capital Securities pursuant to Article IV and ending at the close of business on
the day of mailing of the notice of redemption, or (ii) to register the transfer
of or exchange any Capital Security so selected for redemption in whole or in
part, except, in the case of any such Capital Security to be redeemed in part,
any portion thereof not to be redeemed.

     Every Capital 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 Securities Registrar duly
executed by the Holder or its attorney duly authorized in writing. Each Capital
Securities Certificate surrendered for registration of transfer or exchange
shall be cancelled and subsequently disposed of by the Property Trustee in
accordance with such Person's customary practice.

                                       27
<PAGE>
 
     No service charge shall be made for any registration of transfer or
exchange of Capital 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 Capital Securities
Certificates.

     (b) Notwithstanding any other provision of this Agreement, transfers and
exchanges of Capital Securities Certificates and beneficial interests in a Book-
Entry Capital Securities Certificate of the kinds specified in this Section
5.5(b) shall be made only in accordance with this Section 5.5(b).

     Certificate (other than a Book-Entry Capital Securities Certificate) wishes
     at any time to transfer all or any portion of such Capital Securities
     Certificate to a Person who wishes to take delivery thereof in the form of
     a beneficial interest in a Book-Entry Capital Securities Certificate, such
     transfer may be effected only in accordance with the provisions of this
     Clause (b)(i) and subject to the Applicable Procedures. Upon receipt by the
     Securities Registrar of (A) such Capital Securities Certificate as provided
     in Section 5.5(a) and instructions satisfactory to the Securities Registrar
     directing that a beneficial interest in the Book-Entry Capital Securities
     Certificate of a specified number of Capital Securities not greater than
     the number of Capital Securities represented by such Capital Securities
     Certificate be credited to a specified Clearing Agency Participant's
     account and (B) a Restricted Securities Certificate duly executed by such
     Holder or his attorney duly authorized in writing, then the Securities
     Registrar shall cancel such Capital Securities Certificate (and issue a new
     Capital Securities Certificate in respect of any untransferred portion
     thereof) as provided in Section 5.5(a) and increase the aggregate
     Liquidation Amount of the Book-Entry Capital Securities Certificate by the
     Liquidation Amount represented by such Capital Securities so transferred as
     provided in Section 5.4(c).

          (ii)  Non-Book-Entry Capital Securities Certificate to Non-Book-Entry

     not a Book-Entry Capital Securities Certificate may be transferred, in
     whole or in part, to a Person who takes delivery in the form of another
     Capital Securities Certificate that is not a Book-Entry Capital Securities
     Certificate as provided in Section 5.5(a), provided that if the Capital
                                                --------                    
     Securities Certificate evidences Restricted Securities Certificate, then
     the Securities Registrar shall have received a Restricted Securities
     Certificate duly executed by the transferor Holder or his attorney duly
     authorized in writing in which case the transferee Holder shall take
     delivery in the form of a Restricted Capital Securities Certificate
     (subject to Section 5.5(c)).

          (iii) Exchanges between Book-Entry Capital Securities Certificate and
                ---------------------------------------------------------------
     Non-Book- Entry Capital Securities Certificate. A beneficial interest in a
     ----------------------------------------------                            
     Book-Entry Capital Securities Certificate may be exchanged for a Capital
     Securities Certificate that is not a

     Book-Entry Capital Securities Certificate as provided in Section 5.4,
     provided that such interest shall be exchanged for a Restricted Capital
     --------
     Securities Certificate (subject in each case to Section 5.5(c)).

          (iv)  Certain Initial Transfers of Non-Book-Entry Capital Securities
                --------------------------------------------------------------
     Certificates. In the case of Capital Securities Certificates initially
     ------------                                                          
     issued other than in global form, an initial transfer or exchange of such
     Capital Securities Certificates that does not involve any change in
     beneficial ownership may be made to an Institutional Accredited Investor or
     Investors as if such transfer or exchange were not an initial transfer or
     exchange, provided that written certification shall be provided by the
     transferor and transferee of such Securities to the Securities Registrar
     that such transfer or exchange does not involve a change in beneficial
     ownership.

          (v)    Limitations Relating to Size of Blocks. Notwithstanding any
                 --------------------------------------
     other provision of this Trust Agreement, Capital Securities may only be
     transferred or exchanged in blocks having a Liquidation Amount of not less
     than $100,000. In addition, Capital Securities may not be transferred or
     exchanged by any Holder if, following such transfer or exchange, such
     Holder would have Capital Securities with an aggregate Liquidation Amount
     of less than $100,000. Any transfer, exchange or other disposition of
     Capital Securities in contravention of this Section 5.5(b)(v) shall be
     deemed to be void and of no legal effect whatsoever, any such transferee
     shall be deemed not to be the Holder or Owner of such Capital Security for
     any purpose, including but not limited to the receipt of Distributions on
     such Capital Securities, and such transferee shall be deemed to have no
     interest whatsoever in such Capital Securities.

          (c)   Restricted Capital Securities Legend. Certificates evidencing
                ------------------------------------
Rule 144A Capital Securities, Other Capital Securities and their respective
Successor Capital Securities shall bear a Restricted Capital Securities Legend,
subject to the following:

          (i) subject to the following Clauses of this Section 5.5(c), a Capital
     Securities Certificate or any portion thereof that is exchanged, upon
     transfer or otherwise, for a Book-Entry Capital Securities Certificate or
     any portion thereof shall bear a Restricted Capital Securities Legend;

          (ii) subject to the following Clauses of this Section 5.5(c), a new
     Capital Securities Certificate that is not a Book-Entry Capital Securities
     Certificate and is issued in exchange for another Capital Securities
     Certificate (including a Book-Entry Capital Securities Certificate) or any
     portion thereof, upon transfer or otherwise, shall, bear a Restricted
     Capital Securities Legend;

          (iii) a new Capital Securities Certificate that does not bear a
     Restricted Capital Securities Legend may be issued in exchange for or in
     lieu of a Capital Securities Certificate (other than a Book-Entry Capital
     Securities Certificate) or any portion thereof 

                                       29
<PAGE>
 
     that bears such a legend if, in the Depositor's judgment, placing such a
     legend upon such new Capital Securities Certificate is not necessary to
     ensure compliance with the registration requirements of the Securities Act,
     and the Administrators, at the direction of the Depositor, shall execute
     and deliver such a new Capital Securities Certificate as provided in this
     Article V; and

          (iv) notwithstanding the foregoing provisions of this Section 5.5(c),
     a Successor Capital Securities Certificate of a Capital Securities
     Certificate that does not bear a Restricted Capital Securities Legend shall
     not bear such form of legend unless the Depositor has reasonable cause to
     believe that such Successor Capital Securities Certificate is a "restricted
     security" within the meaning of Rule 144 under the Securities Act, in which
     case the Administrators, at the direction of the Depositor, shall execute
     and deliver a new Capital Securities Certificate bearing a Restricted
     Capital Securities Legend in exchange for such Successor Capital Securities
     Certificate as provided in this Article Five.

          (d)    Before registering for transfer or exchange any Capital
Securities Certificates issued in certificated fully registered form as provided
in Sections 5.2, 5.4 or 5.5 of the Trust Agreement, the Property Trustee as
Securities Registrar may require an Opinion of Counsel or other evidence
satisfactory to it (which may include a certificate from such purchaser or
Holder) that such purchaser or Holder is eligible for the exemptive relief
available under U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 96-23, 95-60, 91-38, 90- 1 or 84-14 or another applicable exemption
with respect to such purchase or holding and, in the case of any purchaser or
Holder relying on any exemption other than PTCE 96-23, 95-60, 91-38, 90-1 or 84-
14, an opinion of counsel or other evidence satisfactory to the Property Trustee
with respect to the availability of such exemption. Any purchaser or Holder of
any Capital Securities or any interest therein will be deemed to have
represented by its purchase and holding thereof that it either (i) is not a Plan
or a Plan Asset Entity and is not purchasing such Capital Securities on behalf
of or with "plan assets" of any Plan, or (ii) is eligible for the exemptive
relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another
applicable exemption with respect to such purchase or holding.

     Section 5.6.  Mutilated, Destroyed, Lost or Stolen Trust Securities

     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, loss or theft of any Trust Securities
Certificate, and (b) there shall be delivered to the Securities Registrar and
the Administrators 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 bona fide purchaser, the
Administrators, or any one of them, on behalf of the Issuer 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 

                                       30
<PAGE>
 
of any new Trust Securities Certificate under this Section 5.6, the
Administrators 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 Issuer Trust corresponding to that evidenced by
the lost, stolen or destroyed Trust Securities Certificate, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

     Section 5.7.  Persons Deemed Holders.

     The Issuer Trustees, the Administrators and the Securities Registrar shall
each 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 none of the Issuer Trustees, the Administrators and the
Securities Registrar shall be bound by any notice to the contrary.

     Section 5.8.  Access to List of Holders' Names and Addresses.

     Each Holder and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee, the Delaware Trustee or the Administrators
accountable by reason of the disclosure of its name and address, regardless of
the source from which such information was derived.

     Section 5.9.  Maintenance of Office or Agency.

     The Property Trustee shall designate, with the consent of the
Administrators, which consent shall not be unreasonably withheld, an office or
offices or agency or agencies where Capital Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Issuer Trustees in respect of the Trust Securities
Certificates may be served. The Property Trustee initially designates The First
National Bank of Chicago, One First National Plaza, Suite 0126, Chicago,
Illinois 60670, Attention: Corporate Trust Administration, as its office and
agency for such purposes. The Property Trustee shall give prompt written notice
to the Depositor, the Administrators and to the Holders of any change in the
location of the Securities Register or any such office or agency.

     Section 5.10. Appointment of Paying Agent.

     The Paying Agent shall make Distributions to Holders from the Payment
Account and shall report the amounts of such Distributions to the Property
Trustee and the Administrators. Any Paying Agent shall have the revocable power
to withdraw funds from the Payment Account solely for the purpose of making the
Distributions referred to above. The Property Trustee may revoke such power and
remove the Paying Agent in its sole discretion. The Paying Agent shall initially
be the Bank. Any Person acting as Paying Agent shall be permitted to resign as
Paying 

                                       31
<PAGE>
 
Agent upon 30 days' written notice to the Administrators and the Property
Trustee. If the Bank shall no longer be the Paying Agent or a successor Paying
Agent shall resign or its authority to act be revoked, the Property Trustee
shall appoint a successor (which shall be a bank or trust company) that is
reasonably acceptable to the Administrators to act as Paying Agent. Such
successor Paying Agent or any additional Paying Agent shall execute and deliver
to the Issuer Trustees an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Issuer 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 Holders in trust for the benefit of
the Holders entitled thereto until such sums shall be paid to such Holders. 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
herein shall apply to the Bank also in its role as Paying Agent, for so long as
the Bank shall act as Paying Agent and, to the extent applicable, to any other
paying agent appointed hereunder. Any reference in this Agreement to the Paying
Agent shall include any co-paying agent unless the context requires otherwise.

     Section 5.11.  Ownership of Common Securities by Depositor.

     At the Time of Delivery, the Depositor shall acquire, and thereafter shall
retain, beneficial and record ownership of the Common Securities. The Depositor
may not transfer the Common Securities except (i) in connection with a
consolidation or merger of the Depositor into another corporation, or any
conveyance, transfer or lease by the Depositor of its properties and assets
substantially as an entirety to any Person, pursuant to Section 8.1 of the
Indenture, or (ii) to the Depositor or an Affiliate thereof in compliance with
applicable law (including the Securities Act of 1933, as amended, and applicable
state securities and blue sky laws), and in either case only upon an effective
assignment and delegation by the Holder of the Common Securities to its
transferee of all of its rights and obligations under the Expense Agreement. To
the fullest extent permitted by law, any attempted transfer of the Common
Securities other than as set forth in the next proceeding sentence shall be
void. The Administrators shall cause each Common Securities Certificate issued
to the Depositor to contain a legend stating substantially "THIS CERTIFICATE IS
NOT TRANSFERABLE EXCEPT TO THE DEPOSITOR OR AN AFFILIATE OF THE DEPOSITOR IN
COMPLIANCE WITH APPLICABLE LAW AND SECTION 5.11 OF THE TRUST AGREEMENT AND ONLY
IN CONNECTION WITH A SIMULTANEOUS DELEGATION AND ASSIGNMENT OF THE EXPENSE
AGREEMENT REFERRED TO THEREIN."

     Section 5.12.  Notices to Clearing Agency.

     To the extent that a notice or other communication to the Holders is
required under this Trust Agreement, for so long as Capital Securities are
represented by a Book-Entry Capital Securities Certificate, the Administrators
and the Issuer Trustee shall give all such notices and communications specified
herein to be given to the Clearing Agency, and shall have no obligations to the
Owners.

     Section 5.13.  Rights of Holders; Waivers of Past Defaults.

     (a) 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 Holders shall not have any right or title therein other than the undivided
beneficial interest in the assets of the Issuer 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 Issuer 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 Holders against
payment of the purchase price therefor will be fully paid and nonassessable by
the Issuer 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.

     (b) For so long as any Capital Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Capital Securities then
Outstanding shall have the right to make such declaration by a notice in writing
to the Property Trustee, the Depositor and the Debenture Trustee.

     At any time after a declaration of acceleration with respect to the
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, if the Property Trustee fails to annul any such declaration and waive
such default, the Holders of at least a Majority in Liquidation Amount of the
Capital Securities, by written notice to the Property Trustee, the Depositor and
the Debenture Trustee, may rescind and annul such declaration and its
consequences if:

          (i) the Depositor has paid or deposited with the Debenture Trustee a
     sum sufficient to pay

                 (A) all overdue installments of interest on all of the
          Debentures,

                 (B) any accrued Additional Interest on all of the Debentures,

                 (C) the principal of (and premium, if any, on) any Debentures
          that have become due otherwise than by such declaration of
          acceleration and interest and Additional Interest thereon at the rate
          borne by the Debentures, and

                 (D) all sums paid or advanced by the Debenture Trustee under
          the Indenture and the reasonable compensation, expenses, disbursements
          and advances of the Debenture Trustee and the Property Trustee, their
          agents and counsel; and

                                       33
<PAGE>
 
          (ii) all Events of Default with respect to the Debentures, other than
     the non- payment of the principal of the Debentures that has become due
     solely by such acceleration, have been cured or waived as provided in
     Section 5.13 of the Indenture.

     The Holders of at least a Majority in Liquidation Amount of the Capital
Securities may, on behalf of the Holders of all the Capital Securities, waive
any past default under the Indenture, except a default in the payment of
principal or interest (unless such default has been cured and a sum sufficient
to pay all matured installments of interest and principal due otherwise than by
acceleration has been deposited with the Debenture Trustee) or a default in
respect of a covenant or provision that under the Indenture cannot be modified
or amended without the consent of the holder of each outstanding Debenture. No
such rescission shall affect any subsequent default or impair any right
consequent thereon.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of any part of the
Capital Securities a record date shall be established for determining Holders of
Outstanding Capital Securities entitled to join in such notice, which record
date shall be at the close of business on the day the Property 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 that 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 that 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
5.13(b).

     (c) For so long as any Capital Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(1)
or 5.1(2) of the Indenture, any Holder of Capital Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of any
amounts payable in respect of Debentures having an aggregate principal amount
equal to the aggregate Liquidation Amount of the Capital Securities of such
Holder (a "Direct Action"). Except as set forth in Section 5.13(b) and this
Section 5.13(c), the Holders of Capital Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in respect
of, the Debentures.

     (d) Except as otherwise provided in paragraphs (a), (b) and (c) of this
Section 5.13, the Holders of at least a Majority in Liquidation Amount of the
Capital Securities may, on behalf 

                                       34
<PAGE>
 
of the Holders of all the Capital Securities, waive any past default or Event of
Default and its consequences. Upon such waiver, any such default or Event of
Default shall cease to exist, and any default or Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Trust
Agreement, but no such waiver shall extend to any subsequent or other default or
Event of Default or impair any right consequent thereon.


                                  ARTICLE VI.

                       Acts of Holders; Meetings; Voting

     Section 6.1.  Limitations on Voting Rights.

     (a) Except as expressly provided in this Trust Agreement and in the
Indenture and as otherwise required by law, no Holder of Capital Securities
shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Issuer 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
Holders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee on behalf of
the Issuer Trust, the Property Trustee shall not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or execute any trust or power conferred on the Debenture Trustee with
respect to the Debentures, (ii) waive any past default that may be waived 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 the Capital 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 Capital Securities.
The Property Trustee shall not revoke any action previously authorized or
approved by a vote of the Holders of the Capital Securities, except by a
subsequent vote of the Holders of the Capital Securities. The Property Trustee
shall notify all Holders of the Capital Securities of any notice of default
received with respect to the Debentures. In addition to obtaining the foregoing
approvals of the Holders of the Capital Securities, prior to taking any of the
foregoing actions, the Issuer Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that such
action shall not cause the Issuer Trust to be taxable as a corporation or
classified as other than a grantor trust for United States Federal income tax
purposes.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Issuer Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material 

                                       35
<PAGE>
 
respect the powers, preferences or special rights of the Capital Securities,
whether by way of amendment to the Trust Agreement or otherwise, or (ii) the
dissolution, winding-up or termination of the Issuer Trust, other than pursuant
to the terms of this Trust Agreement, then the Holders of Outstanding Capital
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 Capital
Securities. Notwithstanding any other provision of this Trust Agreement, no
amendment to this Trust Agreement may be made if, as a result of such amendment,
it would cause the Issuer Trust to be taxable as a corporation or classified as
other than a grantor trust for United States Federal income tax purposes.

     Section 6.2.  Notice of Meetings.

     Notice of all meetings of the Holders of the Capital Securities, stating
the time, place and purpose of the meeting, shall be given by the Property
Trustee pursuant to Section 10.8 to each Holder of Capital Securities, at such
Holder's 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 Holders of the Capital Securities.

     No annual meeting of Holders is required to be held. The Property Trustee,
however, shall call a meeting of the Holders of the Capital Securities to vote
on any matter upon the written request of the Holders of at least 25% in
aggregate Liquidation Amount of the Outstanding Capital Securities and the
Administrators or the Property Trustee may, at any time in their discretion,
call a meeting of the Holders of the Capital Securities to vote on any matters
as to which such Holders are entitled to vote.

     The Holders of at least a Majority in Liquidation Amount of the Capital
Securities, present in person or by proxy, shall constitute a quorum at any
meeting of the Holders of the Capital Securities.

     If a quorum is present at a meeting, an affirmative vote by the Holders
present, in person or by proxy, holding Capital Securities representing at least
a Majority in aggregate Liquidation Amount of the Capital Securities held by the
Holders present, either in person or by proxy, at such meeting shall constitute
the action of the Holders of the Capital Securities, unless this Trust Agreement
requires a greater number of affirmative votes.

                                       36
<PAGE>
 
     Section 6.4.  Voting Rights.

     Holders shall be entitled to one vote for each $1,000 of Liquidation Amount
represented by their Outstanding Trust Securities in respect of any matter as to
which such Holders are entitled to vote.

     Section 6.5.  Proxies, etc.

     At any meeting of Holders, any Holder 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 Property Trustee, or with such other officer or
agent of the Issuer Trust as the Property Trustee 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 Holders 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 Holder 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.  Holder Action by Written Consent.

     Any action that may be taken by Holders at a meeting may be taken without a
meeting if Holders holding at least a Majority in Liquidation Amount of all
Capital Securities entitled to vote in respect of such action (or such larger
proportion thereof as shall be required by any other provision of this Trust
Agreement) shall consent to the action in writing.

     Section 6.7.  Record Date for Voting and Other Purposes.

     For the purposes of determining the Holders 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, the Administrators or Property Trustee may from time to time fix a date,
not more than 90 days prior to the date of any meeting of Holders or the payment
of a distribution or other action, as the case may be, as a record date for the
determination of the identity of the Holders of record for such purposes.

     Section 6.8.  Acts of Holders.

     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 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 otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to the Property Trustee. 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 Trust Agreement and (subject to Section 8.1) conclusive
in favor of the Issuer Trustees and the Administrators, 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 that any Issuer Trustee or Administrator receiving the same deems
sufficient.

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

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

     Without limiting the foregoing, a Holder 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.

     If any dispute shall arise among the Holders, the Administrators or the
Issuer Trustees with respect to the authenticity, validity or binding nature of
any request, demand, authorization, direction, consent, waiver or other Act of
such Holder or Issuer Trustee under this Article VI, 

                                       38
<PAGE>
 
then the determination of such matter by the Property Trustee shall be
conclusive with respect to such matter.

     A Holder may institute a legal proceeding directly against the Depositor
under the Guarantee Agreement to enforce its rights under the Guarantee
Agreement without first instituting a legal proceeding against the Guarantee
Trustee (as defined in the Guarantee Agreement), the Issuer Trust, any Issuer
Trustee, any Administrator or any person or entity.

     Section 6.9.  Inspection of Records.

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


                                 ARTICLE VII.

                        Representations and Warranties

     Section 7.1.  Representations and Warranties of the Property Trustee and
the Delaware Trustee.

     The Property Trustee and the Delaware Trustee, each severally on behalf of
and as to itself, hereby represents and warrants for the benefit of the
Depositor and the Holders that:

     (a) the Property Trustee is a national banking association, duly organized,
validly existing and in good standing under the laws of the United States;

right to execute, deliver and perform its obligations under this Trust Agreement

Trustee enforceable against each of them in accordance with its terms, subject
to bankruptcy, insolvency, fraudulent transfer, 

                                       39

     (f) the execution, delivery and performance of this Trust Agreement has
been duly authorized by all necessary corporate or other action on the part of
the Property Trustee and the Delaware Trustee and does not require any approval
of stockholders of the Property Trustee and the Delaware Trustee and such

Trustee or the Delaware Trustee is a party or by which it is bound, or (iii)
violate any law, governmental rule or regulation of the United States or the
State of Delaware, as the case may be, governing the banking, trust or general
powers of the Property Trustee or the Delaware Trustee (as appropriate in
context) or any order, judgment or decree applicable to the Property Trustee or
the Delaware Trustee;

     (g) neither the authorization, execution or delivery by the Property
Trustee or the Delaware Trustee of this Trust Agreement nor the consummation of
any of the transactions by the Property Trustee or the Delaware Trustee (as

the giving of notice to, the registration with or the taking of any other action
with respect to any governmental authority or agency under any existing law of
the United States or the State of Delaware governing the banking, trust or
general powers of the Property Trustee or the Delaware Trustee (as appropriate
in context); and

     (h) there are no proceedings pending or, to the best of each of the
Property Trustee's and the Delaware Trustee's knowledge, threatened against or
affecting the Property Trustee or the Delaware Trustee in any court or before
any governmental authority, agency or arbitration board or tribunal that,
individually or in the aggregate, would materially and adversely affect the
Issuer Trust or would question the right, power and authority of the Property
Trustee or the Delaware Trustee, as the case may be, to enter into or perform
its obligations as one of the Trustees under this Trust Agreement.

     Section 7.2.  Representations and Warranties of Depositor.

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

     (a) the Trust Securities Certificates issued at the Time of Delivery on

terms and provisions of, and in accordance with the requirements of, this Trust
Agreement and the Holders will be, as of such date, entitled to the benefits of
this Trust Agreement; and

                                       40
<PAGE>
 
     (b) there are no taxes, fees or other governmental charges payable by the
Issuer Trust (or the Issuer Trustees on behalf of the Issuer Trust) under the
laws of the State of Delaware or any political subdivision thereof in connection
with the execution, delivery and performance by either Issuer Trustee of this
Trust Agreement.


                                 ARTICLE VIII.

                    The Issuer Trustees; The Administrators

     Section 8.1.  Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Issuer Trustees and the
Administrators shall be as provided by this Trust Agreement subject to Section
10.10 hereof. Notwithstanding the foregoing, but subject to Section 8.1(c), no
provision of this Trust Agreement shall require any of the Issuer Trustees or
Administrators to expend or risk its or their own funds or otherwise incur any
financial liability in the performance of any of its or their duties hereunder,
or in the exercise of any of its or their rights or powers, if it or 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 Issuer Trustees or the Administrators shall be subject to the
provisions of this Section 8.1. Nothing in this Trust Agreement shall be
construed to release an Administrator from liability for his or her own
negligent action, its own negligent failure to act, or his or her own willful
misconduct. To the extent that, at law or in equity, an Issuer Trustee or
Administrator has duties and liabilities relating to the Issuer Trust or to the
Holders, such Issuer Trustee or Administrator shall not be liable to the Issuer
Trust or to any Holder for such Issuer Trustee's or Administrator'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
Issuer Trustees and Administrators otherwise existing at law or in equity, are
agreed by the Depositor and the Holders to replace such other duties and
liabilities of the Issuer Trustees and Administrators.

     (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 Holder, 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 neither the Issuer Trustees nor
the Administrators are 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 Issuer

                                       41
<PAGE>
 
Trustees expressly set forth elsewhere in this Trust Agreement or, in the case
of the Property Trustee, in the Trust Indenture Act.

     (c) If an Event of Default has occurred and is continuing, the Property
Trustee shall enforce this Trust Agreement for the benefit of the Holders.

     (d) The Property 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
Trust Agreement (including pursuant to Section 10.10), and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. If an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 5.13, the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust 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.

     (e) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee or the Delaware 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:

                 (A) the duties and obligations of the Property Trustee shall be
          determined solely by the express provisions of this Trust Agreement
          (including pursuant to Section 10.10), and the Property Trustee shall
          not be liable except for the performance of such duties and
          obligations as are specifically set forth in this Trust Agreement
          (including pursuant to Section 10.10); and

                 (B) in the absence of bad faith on the part of the Property
          Trustee, the Property 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 Property
          Trustee and conforming to the requirements of this Trust 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 Property Trustee, the Property Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Trust Agreement.

          (ii) 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;

                                       42
<PAGE>
 
          (iii) 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 at least a Majority in Liquidation Amount
     of the Capital 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;

          (iv)  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;

          (v)   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;
     and 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;

          (vi)  the Property Trustee shall not be responsible for monitoring the
     compliance by the Administrators or the Depositor with their respective
     duties under this Trust Agreement, nor shall the Property Trustee be liable
     for the default or misconduct of any other Issuer Trustee, the
     Administrators or the Depositor; and

          (vii) Subject to Section 8.1(c), no provision of this Trust Agreement
     shall require the Property 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
     Property 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 Trust Agreement or adequate indemnity against such risk
     or liability is not reasonably assured to it.

     (f) The Administrators shall not be responsible for monitoring the
compliance by the Issuer Trustees or the Depositor with their respective duties

as the Property Trustee shall deem advisable and in the best interests of the
Holders, 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 contemplated by this Trust

indemnity against the costs, expenses and liabilities that might be incurred by
it in compliance with such request or direction; provided that, nothing
contained in this Section 8.3(g) shall be taken to relieve the Property Trustee,
upon the occurrence of an Event of Default, of its obligation to exercise the
rights and powers vested in it by this Trust Agreement;

     (h) the Property Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,

may refrain from enforcing such remedy or right or taking such other action
until such instructions are received, and (iii) shall be protected in acting in

     (k) except as otherwise expressly provided by this Trust Agreement, the

duty or obligation conferred or imposed on it, in any jurisdiction in which it
shall be illegal, or in which such Person 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 any Issuer Trustee or Administrator 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 Issuer Trust and the Depositor, and the

Debentures.

     Section 8.5.  May Hold Securities.

     The Depositor agrees:

     (a) to pay to the Issuer Trustees from time to time such reasonable
compensation for all services rendered by them hereunder as may be agreed by the

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 Issuer
Trustees upon request for all reasonable expenses, disbursements and advances
incurred or made by the Issuer Trustees in accordance with any provision of this
Trust Agreement (including the reasonable compensation and the expenses and

disbursement or advance as may be attributable to their negligence, bad faith or
wilful misconduct; and

     (c) to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Issuer Trustee, (ii) each Administrator, (iii) any
Affiliate of any Issuer Trustee, (iv) any officer, director, shareholder,

                                       46
<PAGE>
 
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Issuer Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Issuer Trust
and in a manner such Indemnified Person reasonably believed to be within the
scope of authority conferred on such Indemnified Person by this Trust Agreement,
except that no Indemnified Person shall be entitled to be indemnified in respect
of any loss, damage or claim incurred by such Indemnified Person by reason of
negligence, bad faith or wilful misconduct with respect to such acts or
omissions.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement and the removal or resignation of any Issuer Trustee or
Administrator, as the case may be.

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

     The Depositor, any Administrator and any Issuer Trustee may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Issuer Trust, and the Issuer Trust and the Holders of Trust Securities shall
have no rights by virtue of this Trust Agreement in and to such independent
ventures or the income or profits derived therefrom, and the pursuit of any such
venture, even if competitive with the business of the Issuer Trust, shall not be
deemed wrongful or improper. Neither the Depositor, any Administrator nor any
Issuer Trustee shall be obligated to present any particular investment or other
opportunity to the Issuer Trust even if such opportunity is of a character that,
if presented to the Issuer Trust, could be taken by the Issuer Trust, and the
Depositor, any Administrator or any Issuer Trustee shall have the right to take
for its own account (individually or as a partner or fiduciary) or to recommend
to others any such particular investment or other opportunity. Any Issuer
Trustee may engage or be interested in any financial or other transaction with
the Depositor or any Affiliate of the Depositor, or may act as depository for,
trustee or agent for, or act on any committee or body of holders of, securities
or other obligations of the Depositor or its Affiliates.

     Section 8.7.  Corporate Property Trustee Required; Eligibility of Issuer
Trustees and Administrators.

to the Trust Securities. The Property Trustee shall be a Person that is a
national or state chartered bank and eligible pursuant to the Trust Indenture
Act to act as such and that 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 and to the extent permitted by
the Trust Indenture Act, 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 

                                       47

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.

     (b) The Guarantee Agreement and the Indenture shall be deemed to be
specifically described in this Trust Agreement for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

     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 Property Trustee shall have power to appoint, and
upon the written request of the Property Trustee, the Depositor and the
Administrators shall for such purpose join with the Property Trustee 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. Any co-trustee or

     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 by one or more Administrators,
and the Trust Securities shall be delivered by the Property Trustee, 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 Property Trustee specified hereunder shall be
exercised solely by the Property Trustee 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

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.

     (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 a Debenture Event of Default 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 resigning 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.

     Section 8.10.  Resignation and Removal; Appointment of Successor.

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

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Holders and by
appointing a successor Relevant Trustee. The Relevant Trustee shall appoint a
successor by requesting from at least three Persons meeting the eligibility
requirements its expenses and charges to serve as the Relevant Trustee on a form
provided by the Administrators, and selecting the Person who agrees to the
lowest expenses and charges. If the instrument of acceptance by the successor
Issuer Trustee required by Section 8.11 shall not have been delivered to the
Relevant Trustee within 60 days after the giving of such notice of resignation,
the Relevant Trustee may petition, at the expense of the, in the case of the
Property Trustee, Depositor, any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

     The Property Trustee or the Delaware Trustee, or both of them, may be
removed by Act of the Holders of at least a Majority in Liquidation Amount of
the Capital Securities, delivered to the Relevant Trustee (in its individual
capacity and, in the case of the Property Trustee, on behalf of the Issuer
Trust) (i) for cause (including upon the occurrence of an Event of Default
described in subparagraph (d) of the definition thereof with respect to the
Relevant Trustee), or (ii) if a Debenture Event of Default shall have occurred
and be continuing at any time.

     If a resigning Issuer Trustee shall fail to appoint a successor, or if an
Issuer Trustee shall be removed or become incapable of acting as Issuer Trustee,
or if a vacancy shall occur in the office of any Issuer Trustee for any cause,
the Holders of the Capital Securities, by Act of the Holders of not less than
25% in aggregate Liquidation Amount of the Capital Securities then Outstanding
delivered to such Relevant Trustee, may appoint a successor Relevant Trustee or
Trustees, and such successor Issuer Trustee shall comply with the applicable
requirements of Section 8.11. If no successor Relevant Trustee shall have been
so appointed by the Holders of the Capital Securities and accepted appointment
in the manner required by Section 8.11, any Holder, on behalf of such Holder and
all others similarly situated, or any other Issuer Trustee, may petition any
court of competent jurisdiction for the appointment of a successor Relevant
Trustee.

     The Property Trustee shall give notice of each resignation and each removal
of an Issuer Trustee and each appointment of a successor Issuer Trustee to all
Holders in the manner provided in Section 10.8 and shall give notice to the
Depositor and to the Administrators. 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, if any Delaware Trustee who is a natural person dies or becomes, in
the opinion of the Holders of the Common Securities, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by the Property Trustee following the procedures regarding expenses
and charges set forth above (with the successor being a Person who satisfies the
eligibility requirement for the Delaware Trustee set forth in Section 8.7).

     Section 8.11.  Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Relevant Trustee, the
retiring Relevant Trustee and each successor Relevant Trustee with respect to
the Trust Securities shall execute and deliver 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 Issuer 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 Issuer Trust by more than one Relevant
Trustee, it being understood that nothing herein or in such amendment shall
constitute such Relevant Trustees co-trustees 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; but, on request of the Issuer 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 Issuer 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 Business.

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

                                       51
<PAGE>
 
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
Issuer Trust.

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

     Section 8.14.  Trustee May File Proofs of Claim.

     In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Issuer Trust or any other obligor upon the Trust
Securities or the property of the Issuer Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable and irrespective of whether
the Property Trustee shall have made any demand on the Issuer Trust for the
payment of any past due Distributions) shall be entitled and empowered, to the
fullest extent permitted by law, by intervention in such proceeding or
otherwise:

     (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Trust Securities and to file such other
papers or documents as may be necessary or advisable in order to have the claims
of the Property Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

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

     has not previously reported and which in its opinion materially affects the
     Trust Securities.

accordance with Section 8.10.

     (c) The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of an Issuer Trustee shall not operate to
annul, dissolve or terminate the Issuer Trust.

     Section 8.19.  Delegation of Power.

     (a) Any Administrator may, by power of attorney consistent with applicable
law, delegate to any other natural person over the age of 21 his or her power

making any governmental filing; and

     (b) The Administrators shall have power to delegate from time to time to
such of their number the doing of such things and the execution of such
instruments either in the name of the Issuer Trust or the names of the
Administrators or otherwise as the Administrators may deem expedient, to the
extent such delegation is not prohibited by applicable law or contrary to the
provisions of this Trust Agreement.

     Section 8.20.  Appointment of Administrators.

     (a) The Administrators shall initially be Romano L. Peluso and James E.
Murphy, and their successors shall be appointed by the Holders of a Majority in
Liquidation Amount of the Common Securities and resign or be may be removed by
the Holders of a Majority in Liquidation Amount of the Common Securities at any
time. Upon any resignation or removal, the Depositor shall appoint a successor

with the terms of this Trust Agreement. If at any time there is no
Administrator, the Property Trustee or any Holder who has been a Holder of Trust
Securities for at least six months may petition any court of competent
jurisdiction for the appointment of one or more Administrators.

     (b) Whenever a vacancy in the number of Administrators shall occur, until
such vacancy is filled by the appointment of an Administrator in accordance with

                                       54
<PAGE>
 
of this Agreement), shall have all the powers granted to the Administrators and

Agreement, if any Administrator who is a natural person dies or becomes, in the

Securities, incompetent or incapacitated, the vacancy created by such death,
incompetence or incapacity may be filled by the unanimous acts of the remaining
Administrators, if there were at least two of them prior to such vacancy, and by
the Depositor, if there were not two such Administrators immediately prior to
such vacancy (with the successor being a Person who satisfies the eligibility
requirement for Administrators set forth in Section 8.7).


                                  ARTICLE IX.

                      Termination, Liquidation and Merger

     Section 9.1.  Termination Upon Expiration Date.

     Unless earlier terminated, the Issuer Trust shall automatically terminate
on December 30, 2027 (the "Expiration Date"), following the distribution of the
Trust Property in accordance with Section 9.4.

     Section 9.2.  Early Termination.

     The first to occur of any of the following events is an "Early Termination
Event":

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Depositor, in its capacity as the Holder of the Common
Securities, unless the Depositor shall transfer the Common Securities as
provided by Section 5.11, in which case this provision shall refer instead to
any such successor Holder of the Common Securities;

     (b) the written direction to the Property Trustee from all of the Holders
of the Common Securities at any time to terminate the Issuer Trust and to
distribute the Debentures to Holders in exchange for the Capital Securities
(which direction is optional and wholly within the discretion of the Holders of
the Common Securities);

     (c) the redemption of all of the Capital Securities in connection with the
redemption of all the Debentures; and

     (d) the entry of an order for dissolution of the Issuer Trust by a court of
competent jurisdiction.

                                       55
<PAGE>
 
     Section 9.3.  Termination.

     The respective obligations and responsibilities of the Issuer Trustees, the
Administrators and the Issuer Trust created and continued hereby shall terminate
upon the latest to occur of the following: (a) the distribution by the Property
Trustee to Holders of all amounts required to be distributed hereunder upon the
liquidation of the Issuer Trust pursuant to Section 9.4, or upon the redemption
of all of the Trust Securities pursuant to Section 4.2; (b) the payment of any
expenses owed by the Issuer Trust; and (c) the discharge of all administrative
duties of the Administrators, including the performance of any tax reporting
obligations with respect to the Issuer Trust or the Holders.

     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 Issuer Trust shall be
liquidated by the Property Trustee as expeditiously as the Property Trustee
determines to be possible by distributing, after satisfaction of liabilities to
creditors of the Issuer Trust as provided by applicable law, to each Holder 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 less 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 such notices of liquidation shall:

          (i) state the Liquidation Date;

          (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 Property
     Trustee (after consultation with the Administrators) shall deem
     appropriate.

     (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Issuer Trust and distribution of the Debentures to Holders,
the Property Trustee, either itself acting as exchange agent or through the
appointment of a separate exchange agent, shall establish a record date for such
distribution (which shall be not more than 30 days prior to the Liquidation
Date) and, 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 

                                       56
<PAGE>
 
of such Certificates to the exchange agent for exchange, (iii) any Trust
Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of bearing accrued and unpaid interest in an amount
equal to the accumulated and unpaid Distributions on such Trust Securities
Certificates until such certificates are so surrendered (and until such
certificates are so surrendered, no payments of interest or principal will be
made to Holders of Trust Securities Certificates with respect to such
Debentures) and (iv) all rights of Holders holding Trust Securities will cease,
except the right of such Holders to receive Debentures upon surrender of Trust
Securities Certificates.

     (d) If, 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, or if an Early
Termination Event specified in clause (c) of Section 9.2 occurs, the Trust
Property shall be liquidated, and the Issuer Trust shall be dissolved, wound-up
or terminated, by the Property Trustee in such manner as the Property Trustee
determines. In such event, on the date of the dissolution, winding-up or other
termination of the Issuer Trust, Holders will be entitled to receive out of the
assets of the Issuer Trust available for distribution to Holders, after
satisfaction of liabilities to creditors of the Issuer Trust as provided by
applicable law, an amount equal to the Liquidation Amount per Trust Security
plus accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution"). If, upon any such dissolution,
winding up or termination, the Liquidation Distribution can be paid only in part
because the Issuer 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 Issuer Trust on the Trust Securities shall
be paid on a pro rata basis (based upon Liquidation Amounts). The Holders 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 Capital Securities, except that, if a Debenture Event of Default
specified in Section 5.1(1) or 5.1(2) of the Indenture has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities as provided in Section 4.3.

     Section 9.5.  Mergers, Consolidations, Amalgamations or Replacements of
Issuer Trust.

     The Issuer Trust may not merge with or into, consolidate, amalgamate, 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. At the request of the Holders of the Common Securities,
with the consent of the Holders of at least a Majority in Liquidation Amount of
the Capital Securities, the Issuer Trust may merge with or into, consolidate,
amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to 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 Issuer Trust with respect to the Capital
Securities, or (b) substitutes for the Capital Securities other securities

                                       57
<PAGE>
 
having substantially the same terms as the Capital Securities (the "Successor
Securities") so long as the Successor Securities have the same priority as the
Capital Securities with respect to distributions and payments upon liquidation,
redemption and otherwise, (ii) a trustee of such successor entity possessing the
same powers and duties as the Property Trustee is appointed to hold the
Debentures, (iii) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause the Capital Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (iv) such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Capital Securities (including
any Successor Securities) in any material respect, (v) such successor entity has
a purpose substantially identical to that of the Issuer Trust, (vi) prior to
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease, the Property Trustee has received an Opinion of Counsel to the effect
that (a) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Capital Securities (including any Successor
Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Issuer Trust nor such successor entity will be required to register as an
"investment company" under the Investment Company Act, and (vii) the Depositor
or its permitted transferee 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 Agreement.
Notwithstanding the foregoing, the Issuer Trust shall not, except with the
consent of holders of all of the Capital Securities, consolidate, amalgamate,
merge with or into, or be replaced by or convey, transfer or lease its
properties and assets substantially as an entirety to any other entity or permit
any other entity to consolidate, amalgamate, merge with or into, or replace it
if such consolidation, amalgamation, merger, replacement, conveyance, transfer
or lease would cause the Issuer Trust or the successor entity to be taxable as a
corporation or classified as other than a grantor trust for United States
Federal income tax purposes.

     Section 10.1.  Limitation of Rights of Holders.

     Except as set forth in Section 9.2, 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 entitle the legal representatives

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.

     (a) This Trust Agreement may be amended from time to time by the Property
Trustee and the Holders of all of the Common Securities, without the consent of
any Holder of the Capital Securities, (i) to cure any ambiguity, correct or
supplement any provision herein that may be inconsistent with any other
provision herein, 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; provided, however, that such
action shall not adversely affect in any material respect the interests of any
Holder, 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 Issuer Trust
will not be taxable as a corporation or classified as other than a grantor trust
for United States Federal income tax purposes at all times that any Trust
Securities are outstanding or to ensure that the Issuer Trust will not be
required to register as an "investment company" under the Investment Company
Act.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Property Trustee, the Delaware Trustee and
the Holders of all of the Common Securities and with (i) the consent of Holders
of at least a Majority in Liquidation Amount of the Capital Securities, and (ii)
receipt by the Issuer Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees or the
Administrators in accordance with such amendment will not affect the Trust's
status as a grantor trust or cause the Issuer Trust to be taxable as a
corporation or as other than a grantor trust for United States Federal income
tax purposes or affect the Issuer Trust's exemption from status as an
"investment company" under the Investment Company Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Holder (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this Trust Agreement may
not be amended to (i) change the amount or timing of any Distribution on the
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 Holder to institute suit for the enforcement of
any such payment on or after such date; and notwithstanding any other provision
herein, without the unanimous consent of the Holders (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of
this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no Issuer
Trustee shall enter into or consent to any amendment to this Trust Agreement
that would cause the Issuer Trust to fail or cease to qualify for the exemption
from status as an "investment company" under the Investment Company Act or to be
taxable as a corporation or to be classified as other than a grantor trust for
United States Federal income tax purposes.

                                       59

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

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

     (g) Neither the Property Trustee nor the Delaware Trustee shall be required

entitled to receive an Opinion of Counsel and an Officers' Certificate stating
that any amendment to this Trust Agreement is in compliance with this Trust
Agreement.

     Section 10.9.  Agreement Not to Petition.

     Each of the Issuer Trustees and the Depositor agree for the benefit of the

Property Trustee agrees, for the benefit of Holders, that at the expense of the
Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Issuer
Trust or the commencement of such action and raise the defense that the

     (b) The Property Trustee shall be the only Issuer Trustee that is a trustee
for the purposes of the Trust Indenture Act.

     (d) The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Trust Securities as equity securities
representing undivided beneficial interests in the assets of the Issuer Trust.

     Section 10.11.  Acceptance of Terms of Trust Agreement, Guarantee Agreement
and Indenture.

          Re:  State Street Institutional Capital A
               7.94% Capital Securities, Series A
               CUSIP 85748FAA2 (144A)
               --------------------------------------

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 book-
entry-only portion of the 7.94% Capital Securities, Series A (the "Capital
Securities"), of State Street Institutional Capital A, a statutory business
trust formed under the laws of the State of Delaware (the "Issuer"), governed by
the Amended and Restated Trust Agreement, dated as of December 15, 1996, between
State Street Boston Corporation ("the Corporation"), as Depositor, The First
National Bank of Chicago, as Property Trustee, and First Chicago Delaware Inc.,
as Delaware Trustee. The payment of distributions on the Capital Securities and
payments due upon liquidation of the Issuer or redemption of the Capital
Securities, to the extent the Issuer has funds available for the payment
thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of December 15, 1996, between the Corporation and
The First National Bank of Chicago, as Guarantee Trustee with respect to the
Capital Securities.  The Corporation and the Issuer propose to sell the Capital
Securities to Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated (the
"Initial Purchasers") pursuant to a Purchase Agreement, dated December 13, 1996,
by and among the Initial Purchasers, the Issuer and the Corporation, and the
Initial Purchasers wish to take delivery of the Capital Securities through DTC.
The First National Bank of Chicago is acting as transfer agent and registrar
with respect to the Capital Securities (the "Transfer Agent and Registrar").

          To induce DTC to accept the Capital Securities as eligible for deposit
at DTC, and to act in accordance with DTC's rules with respect to the Capital
Securities, the Issuer and the Transfer Agent and Registrar make the following
representations to DTC:

          (d)  Prior to the closing of the sale of the Capital Securities to the
Initial Purchasers on December 20, 1996, there shall be deposited with, or held
by the Transfer Agent and Registrar as custodian for, DTC one or more global
certificates (individually and collectively, the "Global Certificate")
registered in the name of DTC's nominee, Cede & Co., representing an aggregate
of 200,000 Capital Securities and bearing the following legend:

     Unless this certificate is presented by an authorized representative of The
     Depository Trust Company, a New York corporation ("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.

          (e)  The Amended and Restated Trust Agreement of the Issuer provides
for the voting by holders (with no provision for revocation of consents or votes
by subsequent holders) of the Capital 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.

          (f)  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 Capital Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event as soon as
possible but, at least 5 business days prior to the effective date of such
event.

          (g)  In the event of any distribution on, or an offering or issuance
of rights with respect to, the Capital 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
Capital Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Capital Securities or
published by or on behalf of the Issuer (whether by

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 Capital Securities. After establishing
the amount of payment to be made on the Capital 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) 709-1723. Such notices by mail or

          The Issuer or the Transfer Agent and Registrar shall confirm DTC's
receipt of such telecopy by telephoning the Dividend Department at (212) 709-

          (h)  In the event of a redemption by the Issuer of the Capital
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

          (i)  In the event of any invitation to tender the Capital 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

notification to another department is expressly provided for herein, by telecopy
to DTC's Reorganization Department at (212) 709-1093 or (212) 709-1094 and
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

          (j)  All notices and payment advices sent to DTC shall contain the
CUSIP number or numbers of the Capital Securities and the accompanying
designation of the Capital Securities, which, as of the date of this letter, is
"State Street Institutional Capital A, 7.94% Capital Securities, Series A".

          8.   Distribution payments or other cash payments with respect to the
Capital Securities shall be governed by DTC's current Principal and Income
Payments Rider, a copy of which is attached hereto as Annex I.  For purposes of
this letter, the term "Agent" used in Annex I shall be deemed to refer to The
First National Bank of Chicago or any successor Property Trustee under the
Amended and Restated Trust Agreement.

          9.   DTC may 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 Capital Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion:  (a) may request the Issuer or the 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 Capital Securities at any time by giving reasonable 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 Capital 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 Capital Securities, make available one or more
separate global certificates evidencing Capital Securities to any Participant
having Capital Securities credited to its DTC account, or issue definitive
Capital 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
Capital Securities shall be able to obtain definitive Capital 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.

payment, when and as due, of any and all Obligations (as hereinafter defined) to
such Beneficiaries. As used herein, "Obligations" means any costs, expenses or

<PAGE>
 
     Section 1.2. Subordination of Guarantee.   The guarantee and other
liabilities and obligations of the Common Securityholder under this Agreement
shall constitute unsecured obligations of the Common Securityholder and shall
rank subordinate and junior in right of payment to all Senior Indebtedness (as
defined in the Indenture) of the Common Securityholder to the extent and in the
manner set forth in the Indenture with respect to the Debentures, and the
provisions of Article XIII of the Indenture will apply, mutatis mutandis, to the
obligations of the Common Securityholder hereunder. The obligations of the
Common Securityholder hereunder do not constitute Senior Indebtedness (as
defined in the Indenture) of the Common Securityholder.

     Section 1.3. Term of Agreement. This Agreement shall terminate and be of no
further force and effect upon the later of (a) the date on which full payment
has been made of all amounts payable to all holders of all the Capital
Securities (whether upon redemption, liquidation, exchange or otherwise), and
(b) the date on which the Debentures shall have been distributed to the Holders
of the Trust Securities as provided in Article IX; provided, however, that this
Agreement shall continue to be effective or shall be reinstated, as the case may
be, if at any time any holder of Capital Securities or any Beneficiary must
restore payment of any sums paid under the Capital Securities, under any
Obligation, under the Guarantee Agreement dated the date hereof by the Common
Securityholder and The First National Bank of Chicago as guarantee trustee, or
under this Agreement for any reason whatsoever. This Agreement is continuing,
irrevocable, unconditional and absolute.

     Section 1.4. Waiver of Notice. The  Common Securityholder hereby waives
notice of acceptance of this Agreement and of any Obligation to which it applies
or may apply, and the Common Securityholder hereby waives presentment, demand
for payment, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

     Section 1.5. No Impairment. The obligations, covenants, agreements and
duties of the Common Securityholder under this Agreement shall in no way be
affected or impaired by reason of the happening from time to time of any of the
following:

     (a) the extension of time for the payment by the Issuer Trust of all or any
portion of the Obligations or for the performance of any other obligation under,
arising out of, or in connection with, the Obligations;

     (b) any failure, omission, delay or lack of diligence on the part of the
Beneficiaries to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Beneficiaries with respect to the Obligations or any
action on the part of the Issuer Trust granting indulgence or extension of any
kind; or

                                      D-2

     (c) 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 Trust or any of the assets of
the Issuer Trust (other than the liquidation of the Trust in accordance with the
terms thereof).

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

     Section 1.6. Enforcement. A Beneficiary may enforce this Agreement directly
against the Common Securityholder and the Common Securityholder waives any right
or remedy to require that any action be brought against the Issuer Trust or any
other person or entity before proceeding against the Common Securityholder.

     Section 1.7. Subrogation. The Common Securityholder shall be subrogated to
all rights (if any) of the Trust in respect of any amounts paid to the
Beneficiaries by the Common Securityholder under this Agreement; provided,
however, that the Common Securityholder 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 Agreement, if,
at the time of any such payment, any amounts are due and unpaid under this
Agreement.


                                   ARTICLE II

     Section 2.1. Assignment. This Agreement may not be assigned by either party
hereto without the consent of the other, and any purported assignment without
such consent shall be void; except that upon any transfer of the Common
                            ------                                     
Securities, this Agreement shall be assigned and delegated by the Common
Securityholder to its successor with such transfer without any action by either
party hereto.

     Section 2.2. Binding Effect. All guarantees and agreements contained in
this Agreement shall bind the successors, assigns, receivers, trustees and
representatives of the Common Securityholder and shall inure to the benefit of
the Beneficiaries.

     Section 2.3. Amendment. So long as there remains any Beneficiary or any
Capital Securities are outstanding, this Agreement shall not be modified or
amended in any manner adverse to such Beneficiary or to the holders of the
Capital Securities without the consent of such Beneficiary or the holders of the
Capital Securities, as the case may be.

   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 to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Guarantee Trustee hereunder. The right, title and interest of the Guarantee
Trustee, as such, hereunder 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 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 (including pursuant to Section 2.1), and no implied
covenants shall be read into this Guarantee Agreement against the Guarantee
Trustee. If 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.

                                      -6-
<PAGE>
 
   (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 wilful 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:

               (A) the duties and obligations of the Guarantee Trustee shall be
          determined solely by the express provisions of this Guarantee
          Agreement (including pursuant to Section 2.1), 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 (including pursuant to Section 2.1); 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 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
     Amount of the Capital 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.

          (iv) Subject to Section 3.1(b), 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 3.1:

          (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 

                                      -7-
<PAGE>
 
     paper or document reasonably 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.

          (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 any such agent or attorney
     appointed by it with due care 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 

                                      -8-
<PAGE>
 
     such instructions are received, and (C) shall be protected in acting in
     accordance with such instructions.

     (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. Compensation; Indemnity; Fees.

     The Guarantor agrees:

          (a)  to pay to the Guarantee Trustee from time to time such reasonable
     compensation for all services rendered by it hereunder as may be agreed by
     the Guarantor and the Guarantee Trustee 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);

          (b) except as otherwise expressly provided herein, to reimburse the
     Guarantee Trustee upon request for all reasonable expenses, disbursements
     and advances incurred or made by the Guarantee Trustee in accordance with
     any provision of this Guarantee 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; and

          (c) to indemnify the Guarantee Trustee for, and to hold it harmless
     against, any loss, liability or expense incurred without negligence, wilful
     misconduct 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.

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.

                               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

                                      -9-
<PAGE>
 
          (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
     $50,000,000, and shall be a corporation meeting the requirements of Section
     310(a) of the Trust Indenture Act. If such corporation 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
     4.1 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) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the provisions
of Section 310(b) of the Trust Indenture Act.

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

     (a) Subject to Section 4.2(c), the Guarantee Trustee may be appointed or
removed at any time by the action of the Holders of a Majority in Liquidation
Amount of the Capital Securities delivered to the Guarantee Trustee and the
Guarantor (i) for cause or (ii) if a Debenture Event of Default (as defined in
the Trust Agreement) shall have occurred and be continuing at any time.

     (b) Subject to Section 4.2(c), the Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by giving written notice
thereof to the Holders and the Guarantor and by appointing a successor Guarantee
Trustee. The Guarantee Trustee shall appoint a successor by requesting from at
least three Persons meeting the requirements of Section 4.1(a) their expenses
and charges to serve as the Guarantee Trustee, and selecting the Person who
agrees to the lowest expenses and charges.

     (c) The Guarantee Trustee appointed hereunder shall hold office until a
Successor Guarantee Trustee shall have been appointed and shall have accepted
such appointment. No removal or resignation of a Guarantee Trustee shall be
effective 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 and, in the case of any
resignation, 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 Holders and the Guarantor of a notice 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.

     (e) If a resigning Guarantee Trustee shall fail to appoint a successor, or
if a Guarantee Trustee shall be removed or become incapable of acting as
Guarantee Trustee and a replacement shall not be appointed prior to such
resignation or removal, or if a vacancy shall occur in the office of Guarantee
Trustee for any cause, the Holders of the Capital Securities, by the action of
the Holders of record of not less than 25% in aggregate Liquidation Amount (as
defined in the Trust Agreement) of the Capital Securities then Outstanding (as
defined in the Trust Agreement) delivered to such Guarantee Trustee, may 

                                      -10-
<PAGE>
 
appoint a Successor Guarantee Trustee or Trustees. If no successor Guarantee
Trustee shall have been so appointed by the Holders of the Capital Securities
and accepted appointment, any Holder, on behalf of such Holder and all others
similarly situated, or any other Guarantee Trustee, may petition any court of
competent jurisdiction for the appointment of a successor Guarantee Trustee.

                                   ARTICLE V

                                   Guarantee

     Section 5.1. Guarantee.

     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 Trust), as and when due, regardless of any
defense, right of set-off or counterclaim that the Issuer Trust may have or
assert, except the defense of payment. 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 Trust to pay such amounts
to the Holders.

     Section 5.2. Waiver of Notice and Demand.

     The Guarantor hereby waives notice of acceptance of this 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, the Issuer Trust 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.

     Section 5.3. Obligations Not Affected.

     The obligations, covenants, agreements and duties of the Guarantor under
this Guarantee Agreement shall in no way be affected or impaired by reason of
the happening from time to time of any of the following:

          (a) the release or waiver, by operation of law or otherwise, of the
     performance or observance by the Issuer Trust of any express or implied
     agreement, covenant, term or condition relating to the Capital Securities
     to be performed or observed by the Issuer Trust;

          (b) the extension of time for the payment by the Issuer Trust 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 provided in the Indenture), Redemption
     Price, Liquidation Distribution or any other sums payable under the terms
     of the Capital Securities or the extension of time for the performance of
     any other obligation under, arising out of, or in connection with, the
     Capital 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 Capital
     Securities, or any action on the part of the Issuer Trust granting
     indulgence or extension of any kind;

                                      -11-
<PAGE>
 
          (d)  the voluntary or involuntary liquidation, dissolution,
     receivership, insolvency, bankruptcy, assignment for the benefit of
     creditors, reorganization, arrangement, composition or readjustment of debt
     of, or other similar proceedings affecting, the Issuer Trust or any of the
     assets of the Issuer Trust;

          (e) any invalidity of, or defect or deficiency in, the Capital
     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 (other than
     payment of the underlying obligation), 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 Amount of the Capital Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of this Guarantee Agreement or exercising any trust
or power conferred 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 Trust
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 Trust) or upon the distribution of Debentures to Holders as
provided in the Trust Agreement.

     Section 5.6. Subrogation.

     The Guarantor shall be subrogated to all rights (if any) of the Holders
against the Issuer Trust in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement; 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 

                                      -12-
<PAGE>
 
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

     Section 5.7. Independent Obligations.

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer Trust with respect to the Capital 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.

                                   ARTICLE VI

                          Covenants and Subordination

     Section 6.1. Subordination.

     The obligations of the Guarantor under this Guarantee Agreement will
constitute unsecured obligations of the Guarantor and will rank subordinate and
junior in right of payment to all Senior Indebtedness (as defined in the
Indenture) of the Guarantor to the extent and in the manner set forth in the
Indenture with respect to the Debentures, and the provisions of Article XIII of
the Indenture will apply, mutatis mutandis, to the obligations of the Guarantor
hereunder. The obligations of the Guarantor hereunder do not constitute Senior
Indebtedness (as defined in the Indenture) of the Guarantor.

     Section 6.2. Pari Passu Guarantees.

     The obligations of the Guarantor under this Guarantee Agreement shall rank
pari passu with the obligations of the Guarantor under (i) any similar guarantee
agreements issued by the Guarantor on behalf of the holders of preferred or
capital securities issued by any Issuer Trust (as defined in the Indenture),
(ii) the Indenture and the Securities (as defined therein) issued thereunder;
(iii) the Expense Agreement (as defined in the Trust Agreement) and any similar
expense agreements entered into by the Guarantor in connection with the offering
of Capital Securities (as defined in the Indenture) by any Issuer Trust (as
defined in the Indenture), and (iv) any other security, guarantee or other
agreement or obligation that is expressly stated to rank pari passu with the
obligations of the Guarantor under this Guarantee Agreement or with any
obligation that ranks pari passu with the obligations of the Guarantor under
this Guarantee Agreement.

                                  ARTICLE VII

                                  Termination

     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 (as defined in the Trust
Agreement) of all Capital Securities, (ii) the distribution of Debentures to the
Holders in exchange for all of the Capital Securities or (iii) full payment of
the amounts payable in accordance with Article IX of the Trust Agreement upon
liquidation of the 

                                      -13-
<PAGE>
 
Issuer Trust. 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 is required to repay any sums paid with respect to Capital
Securities or this Guarantee Agreement.

                                  ARTICLE VIII

                                 Miscellaneous

     Section 8.1. Successors and Assigns.

     All guarantees and agreements contained in this Guarantee Agreement shall
bind the successors, assigns, receivers, trustees and representatives of the
Guarantor and shall inure to the benefit of the Holders of the Capital
Securities then outstanding. Except in connection with a consolidation, merger
or sale involving the Guarantor that is permitted under Article VIII of the
Indenture and pursuant to which the successor or assignee agrees in writing to
perform the Guarantor's obligations hereunder, the Guarantor shall not assign
its obligations hereunder, and any purported assignment other than in accordance
with this provision shall be void.

     Section 8.2. Amendments.

     Except with respect to any changes that 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 Amount of the
Capital Securities. The provisions of Article VI of the Trust Agreement
concerning meetings of the Holders shall apply to the giving of such approval.
