responsibilities under this Indenture in relation to such Debentures, the
Trustee shall be entitled to receive, and (subject to Section 9.1) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form
and terms thereof have been established in conformity with the provisions of
this Indenture.

         (d) The Trustee shall not be required to authenticate such
Debentures if the issue of such Debentures pursuant to this Indenture shall
affect the Trustee's own rights, duties or immunities under the Debentures
and this Indenture or otherwise in a manner that is not reasonably acceptable
to the Trustee.

SECTION 2.7    REGISTRATION OF TRANSFER AND EXCHANGE.

         (a) Debentures may be exchanged upon presentation thereof at the
office or agency of the Company designated for such purpose in New York, New
York, Wilmington, Delaware or at the office of the Debenture Registrar, for
other Debentures and for a like aggregate principal amount in denominations
of integral multiples of $25, upon payment of a sum sufficient to cover any
tax or other governmental charge in relation thereto, all as provided in this
Section 2.7. In respect of any Debentures so surrendered for exchange, the
Company shall execute, the Trustee shall authenticate and such office or
agency shall deliver in exchange therefor the Debenture or Debentures that
the Debentureholder making the exchange shall be entitled to receive, bearing
numbers not contemporaneously outstanding.


                                       12


         (b) The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in New York, New York or Wilmington,
Delaware or at the office of the Debenture Registrar or such other location
designated by the Company a register or registers (herein referred to as the
"Debenture Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall register the Debentures and the transfers of
Debentures as in this Article II provided and which at all reasonable times
shall be open for inspection by the Trustee. The registrar for the purpose of
registering Debentures and transfer of Debentures as herein provided shall
initially be the Trustee and thereafter as may be appointed by the Company as
authorized by Board Resolution (the "Debenture Registrar"). Upon surrender
for transfer of any Debenture at the office or agency of the Company
designated for such purpose, the Company shall execute, the Trustee shall
authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Debenture or Debentures for a like aggregate
principal amount. All Debentures presented or surrendered for exchange or
registration of transfer, as provided in this Section 2.7, shall be
accompanied (if so required by the Company or the Debenture Registrar) by a
written instrument or instruments of transfer, in form satisfactory to the
Company or the Debenture Registrar, duly executed by the registered holder or
by such holder's duly authorized attorney in writing.

         (c) No service charge shall be made for any exchange or registration
of transfer of Debentures, or issue of new Debentures in case of partial
redemption, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge in relation thereto, other than
exchanges pursuant to Section 2.8, the second paragraph of Section 3.5 and
Section 11.4 not involving any transfer.

         (d) The Company shall not be required (i) to issue, exchange or
register the transfer of any Debentures during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of less than all the Outstanding Debentures and ending at the
close of business on the day of such mailing; nor (ii) to register the
transfer of or exchange any Debentures or portions thereof called for
redemption.

         (e) Debentures may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Indenture. Any
transfer or purported transfer of any Debenture not made in accordance with
this Indenture shall be null and void.

SECTION 2.8    TEMPORARY DEBENTURES.

         Pending the preparation of definitive Debentures, the Company may
execute, and the Trustee shall authenticate and deliver, temporary Debentures
(printed, lithographed, or typewritten). Such temporary Debentures shall be
substantially in the form of the definitive Debentures in lieu of which they
are issued, but with such omissions, insertions and variations as may be
appropriate for temporary Debentures, all as may be determined by the
Company. Every temporary Debenture shall be executed by the Company and be
authenticated by the Trustee upon the same conditions and in substantially
the same manner, and with like effect, as the definitive Debentures. Without
unnecessary delay the Company shall execute and shall furnish definitive
Debentures and thereupon any or all temporary Debentures may be surrendered
in exchange therefor (without charge to the holders), at the office or agency
of the Company designated for the purpose in New York, New York


                                       13


or Wilmington, Delaware and the Trustee shall authenticate and such office or
agency shall deliver in exchange for such temporary Debentures an equal
aggregate principal amount of definitive Debentures, unless the Company
advises the Trustee to the effect that definitive Debentures need not be
executed and furnished until further notice from the Company. Until so
exchanged, the temporary Debentures shall be entitled to the same benefits
under this Indenture as definitive Debentures authenticated and delivered
hereunder.

SECTION 2.9    MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.

         (a) In case any temporary or definitive Debenture shall become
mutilated or be destroyed, lost or stolen, the Company (subject to the next
succeeding sentence) shall execute, and upon the Company's request the
Trustee (subject as aforesaid) shall authenticate and deliver, a new
Debenture bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Debenture, or in lieu of and in substitution
for the Debenture so destroyed, lost, stolen or mutilated. In every case the
applicant for a substituted Debenture shall furnish to the Company and the
Trustee such security or indemnity as may be required by them to save each of
them harmless, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company and the Trustee evidence to their
satisfaction of the destruction, loss or theft of the applicant's Debenture
and of the ownership thereof. The Trustee may authenticate any such
substituted Debenture and deliver the same upon the written request or
authorization of the Chairman, President or any Vice President and the
Treasurer or any Assistant Treasurer of the Company. Upon the issuance of any
substituted Debenture, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses
of the Trustee) connected therewith. In case any Debenture that has matured
or is about to mature shall become mutilated or be destroyed, lost or stolen,
the Company may, instead of issuing a substitute Debenture, pay or authorize
the payment of the same (without surrender thereof except in the case of a
mutilated Debenture) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to
save them harmless, and, in case of destruction, loss or theft, evidence to
the satisfaction of the Company and the Trustee of the destruction, loss or
theft of such Debenture and of the ownership thereof.

         (b) Every replacement Debenture issued pursuant to the provisions of
this Section 2.9 shall constitute an additional contractual obligation of the
Company whether or not the mutilated, destroyed, lost or stolen Debenture
shall be found at any time, or be enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately
with any and all other Debentures duly issued hereunder. All Debentures shall
be held and owned upon the express condition that the foregoing provisions
are exclusive with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Debentures, and shall preclude (to the extent
lawful) any and all other rights or remedies, notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.


                                       14


SECTION 2.10   CANCELLATION.

         All Debentures surrendered for the purpose of payment, redemption,
exchange or registration of transfer shall, if surrendered to the Company or
any paying agent, be delivered to the Trustee for cancellation, or, if
surrendered to the Trustee, shall be canceled by it, and no Debentures shall
be issued in lieu thereof except as expressly required or permitted by any of
the provisions of this Indenture. On request of the Company at the time of
such surrender, the Trustee shall deliver to the Company canceled Debentures
held by the Trustee. In the absence of such request the Trustee may dispose
of canceled Debentures in accordance with its standard procedures and deliver
a certificate of disposition to the Company. If the Company shall otherwise
acquire any of the Debentures, however, such acquisition shall not operate as
a redemption or satisfaction of the indebtedness represented by such
Debentures unless and until the same are delivered to the Trustee for
cancellation.

SECTION 2.11   BENEFIT OF INDENTURE.

         Nothing in this Indenture or in the Debentures, express or implied,
shall give or be construed to give to any Person, other than the parties
hereto and the holders of the Debentures (and, with respect to the provisions
of Article XVI, the holders of Senior Indebtedness) any legal or equitable
right, remedy or claim under or in respect of this Indenture, or under any
covenant, condition or provision herein contained; all such covenants,
conditions and provisions being for the sole benefit of the parties hereto
and of the holders of the Debentures (and, with respect to the provisions of
Article XVI, the holders of Senior Indebtedness).

SECTION 2.12   AUTHENTICATION AGENT.

         (a) So long as any of the Debentures remain Outstanding there may be
an Authenticating Agent for any or all such Debentures, which the Trustee
shall have the right to appoint. Said Authenticating Agent shall be
authorized to act on behalf of the Trustee to authenticate Debentures issued
upon exchange, transfer or partial redemption thereof, and Debentures 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. All references in this Indenture to the authentication of
Debentures by the Trustee shall be deemed to include authentication by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall be a corporation that has a combined capital and surplus,
as most recently reported or determined by it, sufficient under the laws of
any jurisdiction under which it is organized or in which it is doing business
to conduct a trust business, and that is otherwise authorized under such laws
to conduct such business and is subject to supervision or examination by
federal or state authorities. If at any time any Authenticating Agent shall
cease to be eligible in accordance with these provisions, it shall resign
immediately.

         (b) Any Authenticating Agent may at any time resign by giving
written notice of resignation to the Trustee and to the Company. The Trustee
may at any time (and upon request by the Company shall) terminate the agency
of any Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint
an eligible successor


                                       15


Authenticating Agent acceptable to the Company. Any successor Authenticating
Agent, upon acceptance of its appointment hereunder, shall become vested with
all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

                                   ARTICLE III

                            REDEMPTION OF DEBENTURES

SECTION 3.1    REDEMPTION.

         Subject to the Company having received prior approval of the Federal
Reserve, if then required under the applicable capital guidelines, policies
or regulations of the Federal Reserve, the Company may redeem the Debentures
issued hereunder on and after the dates set forth in and in accordance with
the terms of this Article III.

SECTION 3.2    SPECIAL EVENT REDEMPTION.

         Subject to the Company having received the prior approval of the
Federal Reserve, if then required under the applicable capital guidelines,
policies or regulations of the Federal Reserve, if a Special Event has
occurred and is continuing, then, notwithstanding Section 3.3(a) yet subject
to Section 3.3(b), the Company shall have the right upon not less than 30
days nor more than 60 days notice to the holders of the Debentures to redeem
the Debentures, in whole but not in part, for cash within 90 days following
the occurrence of such Special Event (the "90-Day Period") at a redemption
price equal to 100% of the principal amount to be redeemed plus any accrued
and unpaid interest thereon to the date of such redemption (the "Redemption
Price"), provided that if at the time there is available to the Company the
opportunity to eliminate, within the 90-Day Period, a Tax Event by taking
some ministerial action (a "Ministerial Action"), such as filing a form or
making an election, or pursuing some other similar reasonable measure which
has no adverse effect on the Company, the Trust or the holders of the Trust
Securities issued by the Trust, the Company shall pursue such Ministerial
Action in lieu of redemption. The Redemption Price shall be paid prior to
12:00 noon, New York time, on the date of such redemption or such earlier
time as the Company determines, provided that the Company shall deposit with
the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m.,
New York time, on the date such Redemption Price is to be paid.

SECTION 3.3    OPTIONAL REDEMPTION BY COMPANY.

         (a) Subject to the provisions of Section 3.3(b), except as otherwise
may be specified in this Indenture, the Company shall have the right to
redeem the Debentures, in whole or in part, from time to time, on or after
September 30, 2004, at a Redemption Price equal to 100% of the principal
amount to be redeemed plus any accrued and unpaid interest thereon to the
date of such redemption. Any redemption pursuant to this Section 3.3(a) shall
be made upon not less than 30 days' nor more than 60 days' notice to the
holder of the Debentures, at the Redemption Price. If the Debentures are only
partially redeemed pursuant to this Section 3.3, the Debentures shall be
redeemed pro rata or by lot or in such other manner as the Trustee shall deem
appropriate and fair in its discretion. The


                                       16


Redemption Price shall be paid prior to 12:00 noon, New York time, on the
date of such redemption or at such earlier time as the Company determines
provided that the Company shall deposit with the Trustee an amount sufficient
to pay the Redemption Price by 10:00 a.m., New York time, on the date such
Redemption Price is to be paid.

         (b) If a partial redemption of the Debentures would result in the
delisting of the Capital Securities issued by the Trust from American Stock
Exchange or any national securities exchange or other organization on which
the Capital Securities are then listed, the Company shall not be permitted to
effect such partial redemption and may only redeem the Debentures in whole.

SECTION 3.4    NOTICE OF REDEMPTION.

         (a) In case the Company shall desire to exercise such right to
redeem all or, as the case may be, a portion of the Debentures in accordance
with the right reserved so to do, the Company shall, or shall cause the
Trustee to upon receipt of 45 days' written notice from the Company (which
notice shall, in the event of a partial redemption, include a representation
to the effect that such partial redemption will not result in the delisting
of the Capital Securities as described in Section 3.3(b) above), give notice
of such redemption to holders of the Debentures to be redeemed by mailing,
first class postage prepaid, a notice of such redemption not less than 30
days and not more than 60 days before the date fixed for redemption to such
holders at their last addresses as they shall appear upon the Debenture
Register unless a shorter period is specified in the Debentures to be
redeemed. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered
holder receives the notice. In any case, failure duly to give such notice to
the holder of any Debenture designated for redemption in whole or in part, or
any defect in the notice, shall not affect the validity of the proceedings
for the redemption of any other Debentures. In the case of any redemption of
Debentures prior to the expiration of any restriction on such redemption
provided in the terms of such Debentures or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with any such restriction. Each such notice of redemption shall
specify the date fixed for redemption and the Redemption Price and shall
state that payment of the Redemption Price shall be made at the office or
agency of the Company or at the Corporate Trust Office, upon presentation and
surrender of such Debentures, that interest accrued to the date fixed for
redemption shall be paid as specified in said notice and that from and after
said date interest shall cease to accrue. If less than all the Debentures are
to be redeemed, the notice to the holders of the Debentures shall specify the
particular Debentures to be redeemed. If the Debentures are to be redeemed in
part only, the notice shall state the portion of the principal amount thereof
to be redeemed and shall state that on and after the redemption date, upon
surrender of such Debenture, a new Debenture or Debentures in principal
amount equal to the unredeemed portion thereof shall be issued.

         (b) If less than all the Debentures are to be redeemed, the Company
shall give the Trustee at least 45 days' notice in advance of the date fixed
for redemption as to the aggregate principal amount of Debentures to be
redeemed, and thereupon the Trustee shall select, pro rata or by lot or in
such other manner as it shall deem appropriate and fair in its discretion,
the portion or portions (equal to $25 or any integral multiple thereof) of
the Debentures to be redeemed and shall thereafter promptly notify the
Company in writing of the numbers of the Debentures to be redeemed, in whole


                                       17


or in part. The Company may, if and whenever it shall so elect pursuant to
the terms hereof, by delivery of instructions signed on its behalf by its
Chairman, its President or any Vice President, instruct the Trustee or any
paying agent to call all or any part of the Debentures for redemption and to
give notice of redemption in the manner set forth in this Section 3.4, such
notice to be in the name of the Company or its own name as the Trustee or
such paying agent may deem advisable. In any case in which notice of
redemption is to be given by the Trustee or any such paying agent, the
Company shall deliver or cause to be delivered to, or permit to remain with,
the Trustee or such paying agent, as the case may be, such Debenture
Register, transfer books or other records, or suitable copies or extracts
therefrom, sufficient to enable the Trustee or such paying agent to give any
notice by mail that may be required under the provisions of this Section 3.4.

SECTION 3.5    PAYMENT UPON REDEMPTION.

         (a) If the giving of notice of redemption shall have been completed
as above provided, the Debentures or portions of Debentures to be redeemed
specified in such notice shall become due and payable on the date and at the
place stated in such notice at the applicable Redemption Price, and interest
on such Debentures or portions of Debentures shall cease to accrue on and
after the date fixed for redemption, unless the Company shall default in the
payment of such Redemption Price with respect to any such Debenture or
portion thereof. On presentation and surrender of such Debentures on or after
the date fixed for redemption at the place of payment specified in the
notice, said Debentures shall be paid and redeemed at the Redemption Price
(but if the date fixed for redemption is an interest payment date, the
interest installment payable on such date shall be payable to the registered
holder at the close of business on the applicable record date pursuant to
Section 3.3).

         (b) Upon presentation of any Debenture that is to be redeemed in
part only, the Company shall execute and the Trustee shall authenticate and
the office or agency where the Debenture is presented shall deliver to the
holder thereof, at the expense of the Company, a new Debenture of authorized
denomination in principal amount equal to the unredeemed portion of the
Debenture so presented.

SECTION 3.6    NO SINKING FUND.

         The Debentures are not entitled to the benefit of any sinking fund.


                                   ARTICLE IV

                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1    EXTENSION OF INTEREST PAYMENT PERIOD.

         The Company shall have the right, at any time and from time to time
during the term of the Debentures so long as no Event of Default has occurred
and is continuing, to defer payments of interest by extending the interest
payment period of such Debentures for a period not exceeding 20


                                       18


consecutive quarters (the "Extended Interest Payment Period"), during which
Extended Interest Payment Period no interest shall be due and payable;
provided that no Extended Interest Payment Period may extend beyond the
Maturity Date or end on a date other than an Interest Payment Date. To the
extent permitted by applicable law, interest, the payment of which has been
deferred because of the extension of the interest payment period pursuant to
this Section 4.1, shall bear interest thereon at the Coupon Rate compounded
quarterly for each quarter of the Extended Interest Payment Period
("Compounded Interest"). At the end of the Extended Interest Payment Period,
the Company shall calculate (and deliver such calculation to the Trustee) and
pay all interest accrued and unpaid on the Debentures, including any
Additional Interest and Compounded Interest (together, "Deferred Interest")
that shall be payable to the holders of the Debentures in whose names the
Debentures are registered in the Debenture Register on the first record date
after the end of the Extended Interest Payment Period. Before the termination
of any Extended Interest Payment Period, the Company may further extend such
period so long as no Event of Default has occurred and is continuing,
provided that such period together with all such further extensions thereof
shall not exceed 20 consecutive quarters, or extend beyond the Maturity Date
of the Debentures or end on a date other than an Interest Payment Date. Upon
the termination of any Extended Interest Payment Period and upon the payment
of all Deferred Interest then due, the Company may commence a new Extended
Interest Payment Period, subject to the foregoing requirements. No interest
shall be due and payable during an Extended Interest Payment Period, except
at the end thereof, but the Company may prepay at any time all or any portion
of the interest accrued during an Extended Interest Payment Period.

SECTION 4.2    NOTICE OF EXTENSION.

         (a) If the Property Trustee is the only registered holder of the
Debentures at the time the Company selects an Extended Interest Payment
Period, the Company shall give written notice to the Administrative Trustees,
the Property Trustee and the Trustee of its selection of such Extended
Interest Payment Period two Business Days before the earlier of (i) the next
succeeding date on which Distributions on the Trust Securities issued by the
Trust are payable; or (ii) the date the Trust is required to give notice of
the record date, or the date such Distributions are payable, to the American
Stock Exchange or other applicable self-regulatory organization or to holders
of the Capital Securities issued by the Trust, but in any event at least one
Business Day before such record date.

         (b) If the Property Trustee is not the only holder of the Debentures
at the time the Company selects an Extended Interest Payment Period, the
Company shall give the holders of the Debentures and the Trustee written
notice of its selection of such Extended Interest Payment Period at least two
Business Days before the earlier of (i) the next succeeding Interest Payment
Date; or (ii) the date the Company is required to give notice of the record
or payment date of such interest payment to the American Stock Exchange or
other applicable self-regulatory organization or to holders of the Debentures.

         (c) The quarter in which any notice is given pursuant to paragraphs
(a) or (b) of this Section 4.2 shall be counted as one of the 20 quarters
permitted in the maximum Extended Interest Payment Period permitted under
Section 4.1.


                                       19


SECTION 4.3    LIMITATION ON TRANSACTIONS.

         If (i) the Company shall exercise its right to defer payment of
interest as provided in Section 4.1; (ii) there shall have occurred and be
continuing any Event of Default; or (iii) the Company is in default with
respect to its obligations under the Capital Securities Guarantee, then (a)
the Company will not, and will not permit any Subsidiary to, declare or pay
any dividend on, make any distributions with respect to, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of its capital
stock (other than (I) as a result of a reclassification of its capital stock
for another class of its capital stock or (II) declarations or payments of
dividends or distributions on capital stock by a Subsidiary of the Company to
the Company); (b) the Company shall not and will not permit any Subsidiary to
make any payment of interest, principal or premium, if any, or repay,
repurchase or redeem any debt securities issued by the Company which rank
pari passu with or junior to the Debentures or make any guarantee payment
with respect to any guarantee by the Company of the debt securities of any
Subsidiary of the Company if such guarantee ranks pari passu with or junior
to the Debentures; provided, however, that notwithstanding the foregoing the
Company may make payments pursuant to its obligations under the Capital
Securities Guarantee; and (c) the Company shall not redeem, purchase or
acquire less than all of the outstanding Debentures or any of the Capital
Securities.


                                    ARTICLE V

                       PARTICULAR COVENANTS OF THE COMPANY

SECTION 5.1    PAYMENT OF PRINCIPAL AND INTEREST.

         The Company shall duly and punctually pay or cause to be paid the
principal of and interest on the Debentures at the time and place and in the
manner provided herein.

SECTION 5.2    MAINTENANCE OF AGENCY.

         So long as any of the Debentures remain Outstanding, the Company
shall maintain, or shall cause to be maintained, an office or agency in New
York, New York or Wilmington, Delaware, and at such other location or
locations as may be designated as provided in this Section 5.2, where (i)
Debentures may be presented for payment; (ii) Debentures may be presented as
hereinabove authorized for registration of transfer and exchange; and (iii)
notices and demands to or upon the Company in respect of the Debentures and
this Indenture may be given or served, such designation to continue with
respect to such office or agency until the Company shall, by written notice
signed by its President or an Executive Vice President and delivered to the
Trustee, designate some other office or agency for such purposes or any of
them. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, notices and demands.
In addition to any such office or agency, the Company may from time to time
designate one or more offices or agencies outside of New York, New York or
Wilmington, Delaware


                                       20


where the Debentures may be presented for registration or transfer and for
exchange in the manner provided herein, and the Company may from time to time
rescind such designation as the Company may deem desirable or expedient;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain any such office or agency
in New York, New York or Wilmington, Delaware for the purposes above
mentioned. The Company shall give the Trustee prompt written notice of any
such designation or rescission thereof.

SECTION 5.3    PAYING AGENTS.

         (a) The Company shall be the initial paying agent. If the Company
shall appoint one or more paying agents for the Debentures, other than the
Trustee, the Company shall cause each such paying agent to execute and
deliver to the Trustee an instrument in which such agent shall agree with the
Trustee, subject to the provisions of this Section 5.3:

         (i)      that it shall hold all sums held by it as such agent for the
                  payment of the principal of or interest on the Debentures
                  (whether such sums have been paid to it by the Company or by
                  any other obligor of such Debentures) in trust for the
                  benefit of the Persons entitled thereto;

         (ii)     that it shall give the Trustee prompt written notice of any
                  failure by the Company (or by any other obligor of such
                  Debentures) to make any payment of the principal of or
                  interest on the Debentures when the same shall be due and
                  payable;

         (iii)    that it shall, at any time during the continuance of any
                  failure referred to in the preceding paragraph (a)(ii) above,

                  Trustee all sums so held in trust by such paying agent; and

held in trust by the Company or such paying agent, such sums to be held by
the Trustee upon the same terms and conditions as those upon which such sums
were held by the Company or such paying agent; and, upon such payment by any
paying agent to the Trustee, such paying agent shall be released from all
further liability with respect to such money.

SECTION 5.4    APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

Debentures by extending the interest payment period as provided in this
Indenture and such period, or any extension thereof, shall be continuing,
then (a) the Company shall not and will not permit any Subsidiary to declare

debt securities issued by the Company which rank pari passu with or junior to
the Debentures or make any guarantee payments with respect to any guarantee
by the Company of the debt securities of any Subsidiary of the Company if
such guarantee ranks pari passu with or junior in interest to the Debentures;
provided, however, that the Company may make payments pursuant to its

Company's ownership of the Common Securities; (ii) not voluntarily terminate,
wind up or liquidate the Trust, except upon prior approval of the Federal

termination, winding up or liquidation), except in connection with a
distribution of Debentures, the redemption of all of the Trust Securities of
the Trust or certain mergers, consolidations or amalgamations, each as
permitted by the Trust Agreement; and (b) to otherwise continue not to be
treated as an association taxable as a corporation or partnership for United
States federal income tax purposes; and (iii) use its reasonable efforts to
cause each holder of Trust Securities to be treated as owning an individual
beneficial interest in the Debentures. In connection with the distribution of

Debentures on the American Stock Exchange or on such exchange or self
regulatory organization as the Capital Securities are then listed.

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.

                  extension of an interest payment period by the Company in
                  accordance with the terms of this Indenture shall not
                  constitute a default in the payment of interest for this
                  purpose;

         (ii)     the Company defaults in the payment of the principal on the

         (c) At any time after the principal of the Debentures shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the holders of a majority in aggregate principal amount of the
Debentures then Outstanding hereunder, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if:
(i) the Company has paid or deposited with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Debentures and the

such payment or deposit) and the amount payable to the Trustee under Section
9.6; and (ii) any and all Events of Default under this Indenture, other than
the nonpayment of principal on Debentures that shall not have become due by

extend to or shall affect any subsequent default or impair any right
consequent thereon.

         (d) In case the Trustee shall have proceeded to enforce any right
with respect to Debentures under this Indenture and such proceedings shall
have been discontinued or abandoned because of such rescission or annulment
or for any other reason or shall have been determined adversely to the
Trustee, then and in every such case the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company and the Trustee shall continue as
though no such proceedings had been taken.

SECTION 7.2    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         (a) The Company covenants that (1) in case it shall default in the
payment of any installment of interest on any of the Debentures, and such

it shall default in the payment of the principal of any of the Debentures
when the same shall have become due and payable, whether upon maturity of the
Debentures or upon redemption or upon declaration or otherwise, then, upon
demand of the Trustee, the Company shall pay to the Trustee, for the benefit
of the holders of the Debentures, the whole amount that then shall have been
become due and payable on all such Debentures for principal or interest, or
both, as the case may be, with interest upon the overdue principal and (to
the extent that payment of such interest is enforceable under applicable law
and, if the Debentures are held by the Trust or a trustee of the Trust,
without duplication of any other amounts paid by the Trust or trustee in
respect thereof) upon overdue installments of interest at the rate per annum
expressed in the Debentures; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 9.7.

         (b) If the Company shall fail to pay such amounts forthwith upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any action or proceedings at law
or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Company or other
obligor upon the Debentures and collect the moneys adjudged or decreed to be
payable in the manner provided by law out of the property of the Company or
other obligor upon the Debentures, wherever situated.

         (c) In case of any receivership, insolvency, liquidation,
bankruptcy, reorganization, readjustment, arrangement, composition or
judicial proceedings affecting the Company or the creditors or property of
either, the Trustee shall have power to intervene in such proceedings and

as may be otherwise provided by law) be entitled to file such proofs of claim
and other papers and documents as may be necessary or advisable in order to

the date of institution of such proceedings and for any additional amount
that may become due and payable by the Company after such date, and to
collect and receive any moneys or other property payable or deliverable on
any such claim, and to distribute the same after the deduction of the amount
payable


                                       27

bankruptcy or reorganization is hereby authorized by each of the holders of
the Debentures to make such payments to the Trustee, and, in the event that
the Trustee shall consent to the making of such payments directly to such
Debentureholders, to pay to the Trustee any amount due it under Section 9.7.

shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for payment to the Trustee of any
amounts due under Section 9.7, be for the ratable benefit of the holders of
the Debentures. In case of an Event of Default hereunder, the Trustee may in
its discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law.

authorize or consent to or accept or adopt on behalf of any Debentureholder
any plan of reorganization, arrangement, adjustment or composition affecting
the Debentures or the rights of any holder thereof or to authorize the
Trustee to vote in respect of the claim of any Debentureholder in any such

10.4, 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; provided, however, that such
direction shall not be in conflict with any rule of law or with this
Indenture. Subject to the provisions of Section 9.1, the Trustee shall have
the right to decline to follow any such direction if the Trustee in good
faith shall, by a Responsible Officer or Officers of the Trustee, determine
that the proceeding so directed would involve the Trustee in personal
liability. The holders of a majority in aggregate principal amount of the
Debentures at the time Outstanding affected thereby, determined in accordance
with Section 10.4, may on behalf of the holders of all of the Debentures
waive any past default in the performance of any of the covenants contained
herein and its consequences, except (i) a default in the payment of the
principal of or interest on, any of the Debentures as and when the same shall
become due by the terms of such Debentures otherwise than by acceleration
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest and principal has been deposited with the Trustee
(in accordance with Section 7.1(c)); (ii) a default in the covenants
contained in Section 5.7; or (iii) in respect of a covenant or provision
hereof which cannot be modified or amended without the consent of the holder
of each Outstanding Debenture affected; provided, however, that if the
Debentures are held by the Trust or a trustee of the Trust, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in liquidation preference of Trust Securities of the Trust shall
have consented to such waiver or modification to such waiver; provided
further, that if the consent of the holder of each Outstanding Debenture is
required, such waiver shall not be effective until each holder of the Trust
Securities of the Trust shall have consented to such waiver. Upon any such
waiver, the default covered thereby shall be deemed to be cured for all
purposes of this Indenture and the Company, the Trustee and the holders of
the Debentures shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 7.7    UNDERTAKING TO PAY COSTS.

         All parties to this Indenture agree, and each holder of any
Debentures by such holder's 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 7.7
shall not apply to any suit instituted by the Trustee, to any suit instituted
by any Debentureholder, or group of Debentureholders holding more than 10% in
aggregate principal amount of the Outstanding Debentures, or to any suit
instituted by any


                                       30


Debentureholder for the enforcement of the payment of the principal of or
interest on the Debentures, on or after the respective due dates expressed in
such Debenture or established pursuant to this Indenture.

SECTION 7.8    DIRECT ACTION; RIGHT OF SET-OFF.

         In the event that an Event of Default has occurred and is continuing
and such event is attributable to the failure of the Company to pay interest
on or principal of the Debentures on the payment date on which such payment
is due and payable, then a holder of Capital Securities may institute a legal
proceeding directly against the Company for enforcement of payment to such
holder of the principal of or interest on such Debentures having a principal
amount equal to the aggregate Liquidation Amount of the Capital Securities of
such holder (a "Direct Action"). In connection with such Direct Action, the
Company will have a right of set-off under this Indenture to the extent of
any payment made by the Company to such holder of the Capital Securities with
respect to such Direct Action. The Company may not amend this Indenture to
remove this right to institute a suit directly against the Company without
the prior consent of the holders of all the Capital Securities.

to this Indenture, attached hereto and incorporated herein by reference.

SECTION 8.2    ORIGINAL ISSUE OF DEBENTURES.

         Debentures in the aggregate principal amount of $__________ may,

                                   ARTICLE IX

                             CONCERNING THE TRUSTEE

SECTION 9.1    CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

         (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform with respect to the Debentures such duties and only such
duties as are specifically set forth in this Indenture, and no implied


                                       31


covenants shall be read into this Indenture against the Trustee. In case an
Event of Default has occurred that has not been cured or waived, 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 its
own affairs.

         (b) 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:

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

                  (1) the duties and obligations of the Trustee shall with
                  respect to the Debentures be determined solely by the express
                  provisions of this Indenture, and the Trustee shall not be
                  liable with respect to the Debentures except for the
                  performance of such duties and obligations 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 the part of the Trustee,
                  the Trustee may with respect to the Debentures 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 Trustee and conforming to the
                  requirements of this Indenture; but in the case of any such
                  certificates or opinions that by any provision hereof are
                  specifically required to be furnished to the Trustee, the
                  Trustee shall be under a duty to examine the same to determine
                  whether or not they conform to the requirements of this
                  Indenture;

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

         (iii)    the Trustee shall not be liable with respect to any action
                  taken or omitted to be taken by it in good faith in accordance
                  with the direction of the holders of not less than a majority
                  in principal amount of the Debentures at the time Outstanding
                  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 Debentures; and

         (iv)     none of the provisions contained in this Indenture shall
                  require the 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 there is reasonable ground for
                  believing that the repayment of such funds or liability is not
                  reasonably assured to it under the terms of this Indenture or
                  adequate indemnity against such risk is not reasonably assured
                  to it.


                                       32


SECTION 9.2    NOTICE OF DEFAULTS.

         Within five business days after actual knowledge by a Responsible
Officer of the Trustee of the occurrence of any default hereunder with
respect to the Debentures, the Trustee shall transmit by mail to all holders
of the Debentures, as their names and addresses appear in the Debenture
Register, notice of such default, unless such default shall have been cured
or waived; provided, however, that, except in the case default in the payment
of the principal or interest (including any Additional Interest and
Compounded Interest, if any) on any Debenture, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee or a trust committee of the directors and/or Responsible
Officers of the Trustee determines in good faith that the withholding of such
notice is in the interests of the holders of such Debentures; and provided,
further, that in the case of any default of the character specified in
Section 7.1(a)(iii), no such notice to holders of Debentures need be sent
until at least 30 days after the occurrence thereof. For the purposes of this
Section 9.2, the term "default" means any event which is, or after notice or
lapse of time or both, would become, an Event of Default with respect to the
Debentures.

SECTION 9.3    CERTAIN RIGHTS OF TRUSTEE.

         Except as otherwise provided in Section 9.1:

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

         (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by its President or any Vice President and
by the Secretary or an Assistant Secretary or the Treasurer or an Assistant
Treasurer thereof (unless other evidence in respect thereof is specifically
prescribed herein);

         (c) The Trustee shall not be deemed to have knowledge of a default
or an Event of Default, other than an Event of Default specified in Section
7.1(a)(i); or (ii), unless and until it receives written notification of such
Event of Default from the Company or by holders of at least 25% of the
principal amount of the Debentures at the time Outstanding;

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

         (e) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Debentureholders, pursuant to the provisions of this
Indenture, unless such Debentureholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that may be incurred therein or thereby; nothing contained herein shall,
however, relieve the Trustee of the obligation,


                                       33


upon the occurrence of an Event of Default (that has not been cured or
waived) to exercise with respect to the Debentures such of the rights and
powers vested in it by this Indenture, and to use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs;

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

         (g) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
security, or other papers or documents, unless requested in writing to do so
by the holders of not less than a majority in principal amount of the
Outstanding Debentures (determined as provided in Section 10.4); provided,
however, that if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of
such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding. The reasonable expense of every
such examination shall be paid by the Company or, if paid by the Trustee,
shall be repaid by the Company upon demand; and

         (h) 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 9.4    TRUSTEE NOT RESPONSIBLE FOR RECITALS, ETC.

         (a) The Recitals contained herein and in the Debentures shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.

         (b) The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debentures.

         (c) The Trustee shall not be accountable for the use or application
by the Company of any of the Debentures or of the proceeds of such
Debentures, or for the use or application of any moneys paid over by the
Trustee in accordance with any provision of this Indenture, or for the use or
application of any moneys received by any paying agent other than the Trustee.

SECTION 9.5    MAY HOLD DEBENTURES.

         The Trustee or any paying agent or registrar for the Debentures, in
its individual or any other capacity, may become the owner or pledgee of
Debentures with the same rights it would have if it were not Trustee, paying
agent or Debenture Registrar.


                                       34


SECTION 9.6    MONEYS HELD IN TRUST.

         Subject to the provisions of Section 13.5, all moneys received by
the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received, but 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 moneys received by it hereunder except
such as it may agree with the Company to pay thereon.

SECTION 9.7    COMPENSATION AND REIMBURSEMENT.

         (a) The Company covenants and agrees to pay to the Trustee, and the
Trustee shall be entitled to, such compensation (which shall not be limited
by any provision of law in regard to the compensation of a trustee of an
express trust), as the Company and the Trustee may from time to time agree in
writing, for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee, and, except as otherwise expressly provided
herein, the Company shall pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith. The
Company also covenants to indemnify the Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any loss,
liability, claim, action, suit, cost or expense incurred without negligence
or bad faith on the part of the Trustee and arising out of or in connection
with the acceptance or administration of this trust, including the costs and
expenses of defending itself against any claim of liability in the premises.

         (b) The obligations of the Company under this Section 9.7 to
compensate and indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to
that of the Debentures upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the holders of
particular Debentures.

SECTION 9.8    RELIANCE ON OFFICERS' CERTIFICATE.

         Except as otherwise provided in Section 9.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking
or suffering or omitting to take any action hereunder, such matter (unless
other evidence in respect thereof be herein specifically prescribed) may, in
the absence of negligence or bad faith on the part of the Trustee, be deemed
to be conclusively proved and established by an Officers' Certificate
delivered to the Trustee and such certificate, in the absence of negligence
or bad faith on the part of the Trustee, shall be full warrant to the Trustee
for any action taken, suffered or omitted to be taken by it under the
provisions of this Indenture upon the faith thereof.


                                       35


SECTION 9.9    DISQUALIFICATION: CONFLICTING INTERESTS.

         If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee
and the Company shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act.

SECTION 9.10   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee with respect to the Debentures
issued hereunder which shall at all times be a corporation organized and
doing business under the laws of the United States of America or any State or
Territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Commission, authorized under such
laws to exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000, and subject to supervision or examination by
federal, state, territorial, or District of Columbia 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 9.10, 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. The Company
may not, nor may any Person directly or indirectly controlling, controlled
by, or under common control with the Company, serve as Trustee. In case at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 9.10, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.11.

SECTION 9.11   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) The Trustee or any successor hereafter appointed, may at any
time resign by giving written notice thereof to the Company and by
transmitting notice of resignation by mail, first class postage prepaid, to
the Debentureholders, as their names and addresses appear upon the Debenture
Register. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee with respect to Debentures by written
instrument, in duplicate, executed by order of the Board of Directors, one
copy of which instrument shall be delivered to the resigning Trustee and one
copy to the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the mailing 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 Debentures, or any Debentureholder who has been a bona fide holder
of a Debenture or Debentures for at least six months may, subject to the
provisions of Section 9.9, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee.
Such court may thereupon after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

         (b) In case at any time any one of the following shall occur


                                       36


         (i)      the Trustee shall fail to comply with the provisions of
                  Section 9.9 after written request therefor by the Company or
                  by any Debentureholder who has been a bona fide holder of a
                  Debenture or Debentures for at least six months; or

         (ii)     the Trustee shall cease to be eligible in accordance with
                  the provisions of Section 9.10 and shall fail to resign
                  after written request therefor by the Company or by any
                  such Debentureholder; or the Trustee shall become incapable
                  of acting, or shall be adjudged a bankrupt or insolvent, or
                  commence a voluntary bankruptcy proceeding, or a receiver
                  of the Trustee or of its property shall be appointed or
                  consented to, 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, the Company may remove the Trustee
                  with respect to all Debentures and appoint a successor
                  trustee by written instrument, in duplicate, executed by
                  order of the Board of Directors, one copy of which
                  instrument shall be delivered to the Trustee so removed and
                  one copy to the successor trustee, or, subject to the
                  provisions of Section 9.9, unless the Trustee's duty to
                  resign is stayed as provided herein, any Debentureholder
                  who has been a bona fide holder of a Debenture or
                  Debentures for at least six months may, on behalf of that
                  holder and all others similarly situated, petition any
                  court of competent jurisdiction for the removal of the
                  Trustee and the appointment of a successor trustee.  Such
                  court may thereupon after such notice, if any, as it may
                  deem proper and prescribe, remove the Trustee and appoint a
                  successor trustee.

         (c) The holders of a majority in aggregate principal amount of the
Debentures at the time Outstanding may at any time remove the Trustee by so
notifying the Trustee and the Company and may appoint a successor Trustee
with the consent of the Company.

         (d) Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Debentures pursuant to any of the
provisions of this Section 9.11 shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 9.12.

         (e) Any successor trustee appointed pursuant to this Section 9.11
may be appointed with respect to the Debentures, and at any time there shall
be only one Trustee with respect to the Debentures.

SECTION 9.12   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) In case of the appointment hereunder of a successor trustee with
respect to the Debentures, every successor trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested
with all the rights, powers, trusts and duties of the retiring Trustee; but,
on the request of the Company or the successor trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor trustee all the rights, powers, and trusts of
the retiring Trustee and shall duly


                                       37


assign, transfer and deliver to such successor trustee all property and money
held by such retiring Trustee hereunder.

         (b) Upon request of any successor trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and
confirming to such successor trustee all such rights, powers and trusts
referred to in paragraph (a) of this Section 9.12.

         (c) 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 IX.

         (d) Upon acceptance of appointment by a successor trustee as
provided in this Section 9.12, the Company shall transmit notice of the
succession of such trustee hereunder by mail, first class postage prepaid, to
the Debentureholders, as their names and addresses appear upon the Debenture
Register. If the Company fails to transmit such notice within ten days after
acceptance of appointment by the successor trustee, the successor trustee
shall cause such notice to be transmitted at the expense of the Company.

SECTION 9.13   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided that such
corporation shall be qualified under the provisions of Section 9.9 and
eligible under the provisions of Section 9.10, without the execution or
filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding. In case any
Debentures 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
Debentures so authenticated with the same effect as if such successor Trustee
had itself authenticated such Debentures.

SECTION 9.14   PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

         The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship described in Section 311(b) of the
Trust Indenture Act. A Trustee who has resigned or been removed shall be
subject to Section 311(a) of the Trust Indenture Act to the extent included
therein.

                                    ARTICLE X

                         CONCERNING THE DEBENTUREHOLDERS

SECTION 10.1   EVIDENCE OF ACTION BY HOLDERS.

         (a) Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of the
Debentures may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action the
holders of such majority or specified percentage have joined therein may be
evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Debentures in Person or by agent or proxy
appointed in writing.

         (b) If the Company shall solicit from the Debentureholders any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for the determination of
Debentureholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall
have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other action may
be given before or after the record date, but only the Debentureholders of
record at the close of business on the record date shall be deemed to be
Debentureholders for the purposes of determining whether Debentureholders of
the requisite proportion of Outstanding Debentures have authorized or agreed
or consented to such request, demand, authorization, direction, notice,
consent, waiver or other action, and for that purpose the Outstanding
Debentures shall be computed as of the record date; provided, however, that
no such authorization, agreement or consent by such Debentureholders on the
record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after
the record date.

SECTION 10.2   PROOF OF EXECUTION BY DEBENTUREHOLDERS.

         Subject to the provisions of Section 9.1, proof of the execution of
any instrument by a Debentureholder (such proof shall not require
notarization) or his agent or proxy and proof of the holding by any Person of
any of the Debentures shall be sufficient if made in the following manner:

         (a) The fact and date of the execution by any such Person of any
instrument may be proved in any reasonable manner acceptable to the Trustee.

         (b) The ownership of Debentures shall be proved by the Debenture
Register of such Debentures or by a certificate of the Debenture Registrar
thereof.

         (c) The Trustee may require such additional proof of any matter
referred to in this Section 10.2 as it shall deem necessary.


                                       39


SECTION 10.3   WHO MAY BE DEEMED OWNERS.

         Prior to the due presentment for registration of transfer of any
Debenture, the Company, the Trustee, any paying agent, any Authenticating
Agent and any Debenture Registrar may deem and treat the Person in whose name
such Debenture shall be registered upon the books of the Company as the
absolute owner of such Debenture (whether or not such Debenture shall be
overdue and notwithstanding any notice of ownership or writing thereon made
by anyone other than the Debenture Registrar) for the purpose of receiving
payment of or on account of the principal of and interest on such Debenture
(subject to Section 2.3) and for all other purposes; and neither the Company
nor the Trustee nor any paying agent nor any Authenticating Agent nor any
Debenture Registrar shall be affected by any notice to the contrary.

SECTION 10.4   CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED.

         In determining whether the holders of the requisite aggregate
principal amount of Debentures have concurred in any direction, consent or
waiver under this Indenture, the Debentures that are owned by the Company or
any other obligor on the Debentures or by any Person directly or indirectly
controlling or controlled by or under common control with the Company or any
other obligor on the Debentures shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the
purpose of determining whether the Trustee shall be protected in relying on
any such direction, consent or waiver, only Debentures that the Trustee
actually knows are so owned shall be so disregarded. The Debentures so owned
that have been pledged in good faith may be regarded as Outstanding for the
purposes of this Section 10.4, if the pledgee shall establish to the
satisfaction of the Trustee the pledgee's right so to act with respect to
such Debentures and that the pledgee is not a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any such other obligor. In case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

SECTION 10.5   ACTIONS BINDING ON FUTURE DEBENTUREHOLDERS.

         At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 10.1, of the taking of any action by the holders of
the majority or percentage in aggregate principal amount of the Debentures
specified in this Indenture in connection with such action, any holder of a
Debenture that is shown by the evidence to be included in the Debentures the
holders of which have consented to such action may, by filing written notice
with the Trustee, and upon proof of holding as provided in Section 10.2,
revoke such action so far as concerns such Debenture. Except as aforesaid any
such action taken by the holder of any Debenture shall be conclusive and
binding upon such holder and upon all future holders and owners of such
Debenture, and of any Debenture issued in exchange therefor, on registration
of transfer thereof or in place thereof, irrespective of whether or not any
notation in regard thereto is made upon such Debenture. Any action taken by
the holders of the majority or percentage in aggregate principal amount of
the Debentures specified in this Indenture in connection with such action
shall be conclusively binding upon the Company, the Trustee and the holders
of all the Debentures.


                                       40


                                   ARTICLE XI

                             SUPPLEMENTAL INDENTURES

SECTION 11.1   SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF DEBENTUREHOLDERS.

         In addition to any supplemental indenture otherwise authorized by
this Indenture, the Company and the Trustee may from time to time and at any
time enter into an indenture or indentures supplemental hereto (which shall
conform to the provisions of the Trust Indenture Act as then in effect),
without the consent of the Debentureholders, for one or more of the following
purposes:

         (a) to cure any ambiguity, defect, or inconsistency herein, in the
Debentures;

         (b) to comply with Article X;

         (c) to provide for uncertificated Debentures in addition to or in
place of certificated Debentures;

         (d) to add to the covenants of the Company for the benefit of the
holders of all or any of the Debentures or to surrender any right or power
herein conferred upon the Company;

         (e) to add to, delete from, or revise the conditions, limitations,
and restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of Debentures, only as herein set forth;

         (f) to make any change that does not adversely affect the rights of
any Debentureholder in any material respect;

         (g) to provide for the issuance of and establish the form and terms
and conditions of the Debentures, to establish the form of any certifications
required to be furnished pursuant to the terms of this Indenture or of the
Debentures, or to add to the rights of the holders of the Debentures; or

         (h) qualify or maintain the qualification of this Indenture under
the Trust Indenture Act. The Trustee is hereby authorized to join with the
Company in the execution of any such supplemental indenture, and to make any
further appropriate agreements and stipulations that may be therein
contained, but the Trustee 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. Any supplemental indenture
authorized by the provisions of this Section 11.1 may be executed by the
Company and the Trustee without the consent of the holders of any of the
Debentures at the time Outstanding, notwithstanding any of the provisions of
Section 11.2.


                                       41


SECTION 11.2   SUPPLEMENTAL INDENTURES WITH CONSENT OF DEBENTUREHOLDERS.

         With the consent (evidenced as provided in Section 10.1) of the
holders of not less than a majority in aggregate principal amount of the
Debentures at the time Outstanding, the Company, when authorized by Board
Resolutions, and the Trustee may from time to time and at any time enter into
an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act as then in effect) for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying
in any manner not covered by Section 11.1 the rights of the holders of the
Debentures under this Indenture; provided, however, that no such supplemental
indenture shall without the consent of the holders of each Debenture then
Outstanding and affected thereby, (i) extend the fixed maturity of any
Debentures, reduce the principal amount thereof, or reduce the rate or extend
the time of payment of interest thereon, without the consent of the holder of
each Debenture so affected; or (ii) reduce the aforesaid percentage of
Debentures, the holders of which are required to consent to any such
supplemental indenture; provided further, that if the Debentures are held by
the Trust or a trustee of the Trust, such supplemental indenture shall not be
effective until the holders of a majority in liquidation preference of Trust
Securities of the Trust shall have consented to such supplemental indenture;
provided further, that if the consent of the holder of each Outstanding
Debenture is required, such supplemental indenture shall not be effective
until each holder of the Trust Securities of the Trust shall have consented
to such supplemental indenture. It shall not be necessary for the consent of
the Debentureholders affected thereby under this Section 11.2 to approve the
particular form of any proposed supplemental indenture, but it shall be
sufficient if such consent shall approve the substance thereof.

SECTION 11.3   EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture pursuant to the
provisions of this Article XI, this Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Debentures shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and
conditions of any such supplemental indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes.

SECTION 11.4   DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES.

         Debentures affected by a supplemental indenture, authenticated and
delivered after the execution of such supplemental indenture pursuant to the
provisions of this Article XI, may bear a notation in form approved by the
Company, provided such form meets the requirements of any exchange upon which
the Debentures may be listed, as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Debentures so
modified as to conform, in the opinion of the Board of Directors of the
Company, to any modification of this Indenture contained in any such
supplemental indenture may be prepared by the Company, authenticated by the
Trustee and delivered in exchange for the Debentures then Outstanding.


                                       42


SECTION 11.5   EXECUTION OF SUPPLEMENTAL INDENTURES.

         (a) Upon the request of the Company, accompanied by their Board
Resolutions authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of
Debentureholders required to consent thereto as aforesaid, the Trustee shall
join with the Company in the execution of such supplemental indenture unless
such supplemental indenture affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may
in its discretion but shall not be obligated to enter into such supplemental
indenture. The Trustee, subject to the provisions of Section 9.1, may receive
an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article XI is authorized or permitted by, and
conforms to, the terms of this Article XI and that it is proper for the
Trustee under the provisions of this Article XI to join in the execution
thereof.

         (b) Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section 11.5,
the trustee shall transmit by mail, first class postage prepaid, a notice,
setting forth in general terms the substance of such supplemental indenture,
to the Debentureholders as their names and addresses appear upon the
Debenture Register. Any failure of the Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity
of any such supplemental indenture.


                                   ARTICLE XII

                              SUCCESSOR CORPORATION

SECTION 12.1   COMPANY MAY CONSOLIDATE, ETC.

         Nothing contained in this Indenture or in any of the Debentures
shall prevent any consolidation or merger of the Company with or into any
other corporation or corporations (whether or not affiliated with the
Company, as the case may be), or successive consolidations or mergers in
which the Company, as the case may be, or its successor or successors shall
be a party or parties, or shall prevent any sale, conveyance, transfer or
other disposition of the property of the Company, as the case may be, or its
successor or successors as an entirety, or substantially as an entirety, to
any other corporation (whether or not affiliated with the Company, as the
case may be, or its successor or successors) authorized to acquire and
operate the same; provided, however, the Company hereby covenants and agrees
that, (i) upon any such consolidation, merger, sale, conveyance, transfer or
other disposition, the due and punctual payment, in the case of the Company,
of the principal of and interest on all of the Debentures, according to their
tenor and the due and punctual performance and observance of all the
covenants and conditions of this Indenture to be kept or performed by the
Company as the case may be, shall be expressly assumed, by supplemental
indenture (which shall conform to the provisions of the Trust Indenture Act,
as then in effect) satisfactory in form to the Trustee executed and delivered
to the Trustee by the entity formed by such consolidation, or into which the
Company, as the case may be, shall have been merged, or by the entity which
shall have acquired such property; (ii) in case the Company consolidates with
or merges into another Person


                                       43


or conveys or transfers its properties and assets substantially then as an
entirety to any Person, the successor Person is organized under the laws of
the United States or any state or the District of Columbia; and (iii)
immediately after giving effect thereto, an Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of
Default, shall have occurred and be continuing.

SECTION 12.2   SUCCESSOR CORPORATION SUBSTITUTED.

         (a) In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition and upon the assumption by the successor
corporation, by supplemental indenture, executed and delivered to the Trustee
and satisfactory in form to the Trustee, of, in the case of the Company, the
due and punctual payment of the principal of and interest on all of the
Debentures Outstanding and the due and punctual performance of all of the
covenants and conditions of this Indenture to be performed by the Company, as
the case may be, such successor corporation shall succeed to and be
substituted for the Company, with the same effect as if it had been named as
the Company herein, and thereupon the predecessor corporation shall be
relieved of all obligations and covenants under this Indenture and the
Debentures.

         (b) In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition such changes in phraseology and form (but not
in substance) may be made in the Debentures thereafter to be issued as may be
appropriate.

         (c) Nothing contained in this Indenture or in any of the Debentures
shall prevent the Company from merging into itself or acquiring by purchase
or otherwise all or any part of the property of any other Person (whether or
not affiliated with the Company).

SECTION 12.3   EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

         The Trustee, subject to the provisions of Section 9.1, may receive
an Opinion of Counsel as conclusive evidence that any such consolidation,
merger, sale, conveyance, transfer or other disposition, and any such
assumption, comply with the provisions of this Article XII.

SECTION 13.1   SATISFACTION AND DISCHARGE OF INDENTURE.

         If at any time: (a) the Company shall have delivered to the Trustee
for cancellation all Debentures theretofore authenticated (other than any
Debentures that shall have been destroyed, lost or stolen and that shall have
been replaced or paid as provided in Section 2.9) and Debentures for whose
payment money or Governmental Obligations have theretofore been deposited in
trust or segregated and held in trust by the Company (and thereupon repaid to
the Company or discharged from such trust, as provided in Section 13.5); or
(b) all such Debentures not theretofore delivered


                                       44


to the Trustee for cancellation shall have become due and payable, or are by
their terms to become due and payable within one year or are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption, and the Company shall deposit or cause to
be deposited with the Trustee as trust funds the entire amount in moneys or
Governmental Obligations sufficient or a combination thereof, sufficient in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
at maturity or upon redemption all Debentures not theretofore delivered to
the Trustee for cancellation, including principal and interest due or to
become due to such date of maturity or date fixed for redemption, as the case
may be, and if the Company shall also pay or cause to be paid all other sums
payable hereunder by the Company; then this Indenture shall thereupon cease
to be of further effect except for the provisions of Sections 2.3, 2.7, 2.9,
5.1, 5.2, 5.3 and 9.7, that shall survive until the date of maturity or
redemption date, as the case may be, and Sections 9.7 and 13.5, that shall
survive to such date and thereafter, and the Trustee, on demand of the
Company and at the cost and expense of the Company, shall execute proper

with the Trustee as trust funds moneys or an amount of Governmental
Obligations sufficient in the opinion of a nationally recognized certified
public accounting firm to pay at maturity or upon redemption all Debentures
not theretofore delivered to the Trustee for cancellation, including
principal and interest due or to become due to such date of maturity or date
fixed for redemption, as the case may be, and if the Company shall also pay
or cause to be paid all other sums payable hereunder by the Company, then
after the date such moneys or Governmental Obligations, as the case may be,
are deposited with the Trustee, the obligations of the Company under this
Indenture shall cease to be of further effect except for the provisions of
Sections 2.3, 2.7, 2.9, 5.1, 5.2, 5.3, 9.6, 9.7 and 13.5 hereof that shall
survive until such Debentures shall mature and be paid. Thereafter, Sections
9.7 and 13.5 shall survive.

SECTION 13.3   DEPOSITED MONIES TO BE HELD IN TRUST.

         All monies or Governmental Obligations deposited with the Trustee
pursuant to Sections 13.1 or 13.2 shall be held in trust and shall be

(including the Company acting as its own paying agent), to the holders of the
Debentures for the payment or redemption of which such moneys or Governmental
Obligations have been deposited with the Trustee.


                                       45

         Any monies or Governmental Obligations deposited with any paying
agent or the Trustee, or then held by the Company in trust, for payment of
principal of or interest on the Debentures that are not applied but remain
unclaimed by the holders of such Debentures for at least two years after the
date upon which the principal of or interest on such Debentures shall have
respectively become due and payable, shall be repaid to the Company, as the
case may be, on May 31 of each year or (if then held by the Company) shall be
discharged from such trust; and thereupon the paying agent and the Trustee
shall be released from all further liability with respect to such monies or
Governmental Obligations, and the holder of any of the Debentures entitled to
receive such payment shall thereafter, as an unsecured general creditor, look
only to the Company for the payment thereof.

         In any case where the date of maturity of interest or principal of
any Debenture or the date of redemption of any Debenture shall not be a
Business Day, then payment of interest or principal may be made on the next
succeeding Business Day with the same force and effect as if made on the
nominal date of maturity or redemption, and no interest shall accrue for the
period after such nominal date.


                                       48


SECTION 15.9   CONFLICT WITH TRUST INDENTURE ACT.

         If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.

SECTION 15.10  COUNTERPARTS.

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

SECTION 15.11  SEPARABILITY.

         In case any one or more of the provisions contained in this
Indenture or in the Debentures shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Indenture or
of the Debentures, but this Indenture and the Debentures shall be construed
as if such invalid or illegal or unenforceable provision had never been
contained herein or therein.

SECTION 15.12  ASSIGNMENT.

         The Company shall have the right at all times to assign any of its
respective rights or obligations under this Indenture to a direct or indirect
wholly owned Subsidiary of the Company, provided that, in the event of any
such assignment, the Company shall remain liable for all such obligations.
Subject to the foregoing, this Indenture is binding upon and inures to the
benefit of the parties thereto and their respective successors and assigns.
This Indenture may not otherwise be assigned by the parties thereto.

SECTION 15.13  ACKNOWLEDGMENT OF RIGHTS.

         The Company acknowledges that, with respect to any Debentures held
by the Trust or a trustee of the Trust, if the Property Trustee fails to
enforce its rights under this Indenture as the holder of the Debentures held
as the assets of the Trust, any holder of Capital Securities may, to the
extent permitted under applicable law, institute legal proceedings directly
against the Company to enforce such Property Trustee's rights under this
Indenture without first instituting any legal proceedings against such
Property Trustee or any other person or entity. Notwithstanding the
foregoing, if an Event of Default has occurred and is continuing and such
event is attributable to the failure of the Company to pay interest or
principal on the Debentures on the date such interest or principal is
otherwise payable (or in the case of redemption, on the redemption date), the
Company acknowledges that a holder of Capital Securities may directly
institute a proceeding for enforcement of payment to such holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Capital Securities of such holder on
or after the respective due date specified in the Debentures.


                                       49


SECTION 15.14  ADDITIONAL PROVISIONS FOR THE PAYMENT OF EXPENSES.

         In connection with the offering, sale and issuance of the Debentures
to the Trust and in connection with the sale of the Trust Securities by the
Trust, the Company, in its capacity as borrower with respect to the
Debentures, and not in limitation of the provisions contained in the "Expense
Agreement" (as such term is defined in the Trust Agreement) or the other
provisions contained herein, agrees to pay the following:

                  (a) All debts and other obligations (other than with respect
         to the Capital Securities) of the Trust and all costs and expenses of
         the Trust (including costs and expenses relating to the organization of
         the Trust, the fees and expenses of the Property Trustee and the other
         costs and expenses relating to the operation of the Trust); and

                  (b) Any and all taxes and all costs and expenses with respect
         thereto (other than United States withholding taxes) to which the Trust
         might become subject.

The foregoing obligations of the Company are for the benefit of, and shall be
enforceable by, any person to whom such debts, obligations, costs, expenses
and liabilities are owed (a "Creditor") whether or not such Creditor has
received notice thereof. Not in limitation of the provisions of the Expense
Agreement, any such Creditor may enforce such obligations of the Company
directly against the Company, and the Company irrevocably waives any right or
remedy to require that any such Creditor take any action against the Trust or
any other person before proceeding against the Company. The Company also
agrees to execute such additional agreements as may be necessary or desirable
to give full effect to the foregoing.


                                   ARTICLE XVI

                           SUBORDINATION OF DEBENTURES

SECTION 16.1   AGREEMENT TO SUBORDINATE.

         The Company covenants and agrees, and each holder of Debentures
issued hereunder by such holder's acceptance thereof likewise covenants and
agrees, that all Debentures shall be issued subject to the provisions of this
Article XVI; and each holder of a Debenture, whether upon original issue or
upon transfer or assignment thereof, accepts and agrees to be bound by such
provisions. The payment by the Company of the principal of and interest on
all Debentures issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all Senior Debt, Subordinated Debt and Additional
Senior Obligations (collectively, "Senior Indebtedness") to the extent
provided herein, whether outstanding at the date of this Indenture or
thereafter incurred. No provision of this Article XVI shall prevent the
occurrence of any default or Event of Default hereunder.


                                       50


SECTION 16.2   DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR ADDITIONAL SENIOR
               OBLIGATIONS.

         In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment
due on any Senior Indebtedness of the Company, or in the event that the
maturity of any Senior Indebtedness of the Company has been accelerated
because of a default, then, in either case, no payment shall be made by the
Company with respect to the principal (including redemption payments) of or
interest on the Debentures. In the event that, notwithstanding the foregoing,
any payment shall be received by the Trustee when such payment is prohibited
by the preceding sentence of this Section 16.2, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders
of Senior Indebtedness or their respective representatives, or to the trustee
or trustees under any indenture pursuant to which any of such Senior
Indebtedness may have been issued, as their respective interests may appear,
but only to the extent that the holders of the Senior Indebtedness (or their
representative or representatives or a trustee) notify the Trustee in writing
within 90 days of such payment of the amounts then due and owing on the
Senior Indebtedness and only the amounts specified in such notice to the
Trustee shall be paid to the holders of Senior Indebtedness.

SECTION 16.3   LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         (a) Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due upon all
Senior Indebtedness of the Company shall first be paid in full, or payment
thereof provided for in money in accordance with its terms, before any
payment is made by the Company on account of the principal or interest on the
Debentures; and upon any such dissolution or winding-up or liquidation or
reorganization, any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
which the holders of the Debentures or the Trustee would be entitled to
receive from the Company, except for the provisions of this Article XVI,
shall be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or
distribution, or by the holders of the Debentures or by the Trustee under
this Indenture if received by them or it, directly to the holders of Senior
Indebtedness of the Company (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders, as calculated
by the Company) or their representative or representatives, or to the trustee
or trustees under any indenture pursuant to which any instruments evidencing
such Senior Indebtedness may have been issued, as their respective interests
may appear, to the extent necessary to pay such Senior Indebtedness in full,
in money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the holders of Debentures or to the
Trustee.

         (b) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received
by the Trustee before all Senior Indebtedness of the Company is paid


                                       51


in full, or provision is made for such payment in money in accordance with
its terms, such payment or distribution shall be held in trust for the
benefit of and shall be paid over or delivered to the holders of such Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing
such Senior Indebtedness may have been issued, and their respective interests
may appear, as calculated by the Company, for application to the payment of
all Senior Indebtedness of the Company, as the case may be, remaining unpaid
to the extent necessary to pay such Senior Indebtedness in full in money in
accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Senior Indebtedness.

         (c) For purposes of this Article XVI, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this
Article XVI with respect to the Debentures to the payment of all Senior
Indebtedness of the Company, as the case may be, that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment;
and (ii) the rights of the holders of such Senior Indebtedness are not,
without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Company with, or the merger of the
Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety,
or substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article XII shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section
16.3 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
XII. Nothing in Section 16.2 or in this Section 16.3 shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 9.7.

SECTION 16.4   SUBROGATION.

         (a) Subject to the payment in full of all Senior Indebtedness of the
Company, the rights of the holders of the Debentures shall be subrogated to
the rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Indebtedness until the principal of and
interest on the Debentures shall be paid in full; and, for the purposes of
such subrogation, no payments or distributions to the holders of such Senior
Indebtedness of any cash, property or securities to which the holders of the
Debentures or the Trustee would be entitled except for the provisions of this
Article XVI, and no payment over pursuant to the provisions of this Article
XVI to or for the benefit of the holders of such Senior Indebtedness by
holders of the Debentures or the Trustee, shall, as between the Company, its
creditors other than holders of Senior Indebtedness of the Company, and the
holders of the Debentures, be deemed to be a payment by the Company to or on
account of such Senior Indebtedness. It is understood that the provisions of
this Article XVI are and are intended solely for the purposes of defining the
relative rights of the holders of the Debentures, on the one hand, and the
holders of such Senior Indebtedness on the other hand.


                                       52


         (b) Nothing contained in this Article XVI or elsewhere in this
Indenture or in the Debentures is intended to or shall impair, as between the
Company, its creditors (other than the holders of Senior Indebtedness of the
Company), and the holders of the Debentures, the obligation of the Company,
which is absolute and unconditional, to pay to the holders of the Debentures
the principal of and interest on the Debentures as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the holders of the Debentures and
creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the Trustee or the holder of any Debenture from
exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article XVI
of the holders of such Senior Indebtedness in respect of cash, property or
securities of the Company, as the case may be, received upon the exercise of
any such remedy.

         (c) Upon any payment or distribution of assets of the Company
referred to in this Article XVI, the Trustee, subject to the provisions of
Article IX, and the holders of the Debentures shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the holders of the
Debentures, for the purposes of ascertaining the Persons entitled to
participate in such distribution, the holders of Senior Indebtedness and
other indebtedness of the Company, as the case may be, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this Article XVI.

SECTION 16.5   TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each holder of Debentures by such holder's acceptance thereof
authorizes and directs the Trustee on such holder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article XVI and appoints the Trustee such holder's
attorney-in-fact for any and all such purposes.

SECTION 16.6   NOTICE BY THE COMPANY.

         (a) The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Debentures pursuant to the provisions of this Article XVI. Notwithstanding
the provisions of this Article XVI 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 of monies to or by the Trustee
in respect of the Debentures pursuant to the provisions of this Article XVI,
unless and until a Responsible Officer of the Trustee shall have received
written notice thereof from the Company or a holder or holders of Senior
Indebtedness or from any trustee therefor; and before the receipt of any such
written notice, the Trustee, subject to the provisions of Section 9.1, shall
be entitled in all respects to assume that no such facts exist; provided,
however, that if the Trustee shall not have received the notice provided for
in this Section 16.6 at least two Business Days prior to the date upon which
by the terms hereof any money may


                                       53


become payable for any purpose (including, without limitation, the payment of
the principal of or interest on any Debenture), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power
and authority to receive such money and to apply the same to the purposes 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.

         (b) The Trustee, subject to the provisions of Section 9.1, shall be
entitled to conclusively rely on the delivery to it of a written notice by a
Person representing himself to be a holder of Senior Indebtedness of the
Company (or a trustee on behalf of such holder) to establish that such notice
has been given by a holder of such Senior Indebtedness or a trustee on behalf
of any such holder or holders. 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 such Senior Indebtedness to participate in any payment
or distribution pursuant to this Article XVI, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of such 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
XVI, 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 16.7   RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

         (a) The Trustee in its individual capacity shall be entitled to all
the rights set forth in this Article XVI in respect of any Senior
Indebtedness at any time held by it, to the same extent as any other holder
of Senior Indebtedness, and nothing in this Indenture shall deprive the
Trustee of any of its rights as such holder. The Trustee's right to
compensation and reimbursement of expenses as set forth in Section 9.7 shall
not be subject to the subordination provisions of this Article XVI.

         (b) With respect to the holders of Senior Indebtedness of the
Company, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article XVI,
and no implied covenants or obligations with respect to the holders of such
Senior Indebtedness shall be read into this Indenture against the Trustee.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
such Senior Indebtedness and, subject to the provisions of Section 9.1, the
Trustee shall not be liable to any holder of such Senior Indebtedness if it
shall pay over or deliver to holders of Debentures, the Company or any other
Person money or assets to which any holder of such Senior Indebtedness shall
be entitled by virtue of this Article XVI or otherwise.

SECTION 16.8   SUBORDINATION MAY NOT BE IMPAIRED.

         (a) No right of any present or future holder of any Senior
Indebtedness of the Company to enforce subordination as herein provided shall
at any time in any way be prejudiced or impaired by any act or failure to act
on the part of the Company or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company with the terms,
provisions and


                                       54


covenants of this Indenture, regardless of any knowledge thereof that any
such holder may have or otherwise be charged with.

         (b) Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time
and from time to time, without the consent of or notice to the Trustee or the
holders of the Debentures, without incurring responsibility to the holders of
the Debentures and without impairing or releasing the subordination provided
in this Article XVI or the obligations hereunder of the holders of the
Debentures to the holders of such 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, such Senior Indebtedness, or otherwise
amend or supplement in any manner such Senior Indebtedness or any instrument
evidencing the same or any agreement under which such Senior Indebtedness is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii)
release any Person liable in any manner for the collection of such Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Company and any other Person.

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

         CUSIP No. ______ ___ __

         Heartland Financial USA, Inc., a Delaware corporation (the "Company,"
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to,
_________________________ or registered assigns, the principal sum of
_____________________________ ($) on September 30, 2029 (the "Stated Maturity"),
and to pay interest on said principal sum from ________ __, 1999, or from the
most recent interest payment date (each such date, an "Interest Payment Date")
to which interest has been paid or duly provided for, quarterly (subject to
deferral as set forth herein) in arrears on March 31, June 30, September 30 and
December 31 of each year commencing December 31, 1999, at the rate of ____% per
annum until the principal hereof shall have become due and payable, and on any
overdue principal and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum compounded quarterly. The amount of interest
payable on any Interest Payment Date shall be computed on the basis of a 360-day
year of twelve 30-day months. The amount of interest for any partial period
shall be computed on the basis of the number of days elapsed in a 360-day year
of twelve 30-day months. In the event that any date on which interest is payable
on this Debenture is not a business day, then payment of interest payable on
such date 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) except that,
if such business day is in the next succeeding calendar year, payment of such
interest will be made on the immediately preceding business day, in each case,
with the same force and effect as if made on such date. The interest installment
so payable, and punctually paid or duly provided for, on any Interest Payment
Date shall, as provided in the Indenture, be paid to the person in whose name
this Debenture (or one or more Predecessor Debentures, as defined in said
Indenture) is registered at the close of business on the regular record date for
such interest installment, which shall be the close of business on the business
day next preceding such Interest Payment Date unless otherwise provided in the
Indenture. Any such interest installment not punctually paid or duly provided
for shall forthwith cease to be payable to the registered holders on such
regular record date and may be paid to the Person in whose


                                       1


name this Debenture (or one or more Predecessor Debentures) is registered at
the close of business on a special record date to be fixed by the Trustee for
the payment of such defaulted interest, notice whereof shall be given to the
registered holders of the Debentures not less than 10 days prior to such
special record date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which
the Debentures may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. The principal of and
the interest on this Debenture shall be payable at the office or agency of
the Trustee maintained for that purpose in any coin or currency of the United
States of America that at the time of payment is legal tender for payment of
public and private debts; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the registered holder at
such address as shall appear in the Debenture Register. Notwithstanding the
foregoing, so long as the holder of this Debenture is the Property Trustee,
the payment of the principal of and interest on this Debenture shall be made
at such place and to such account as may be designated by the Trustee. The
Stated Maturity may be shortened at any time by the Company to any date not
earlier than September 30, 2004, subject to the Company having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines, policies or regulations of the Federal Reserve.

         The indebtedness evidenced by this Debenture 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 Debenture is
issued subject to the provisions of the Indenture with respect thereto. Each
holder of this Debenture, 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 action as may be necessary or appropriate to
acknowledge or 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, hereby 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.

         This Debenture shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any
purpose until the Certificate of Authentication hereon shall have been signed

                          ____% SUBORDINATED DEBENTURE

                                   (CONTINUED)


         This Debenture is one of the subordinated debentures of the Company
(herein sometimes referred to as the "Debentures"), specified in the
Indenture, all issued or to be issued under and pursuant to an Indenture
dated as of _________, 1999 (the "Indenture") duly executed and delivered
between the Company and First Union Trust Company, National Association, as
Trustee (the "Trustee"), to which Indenture reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the
Debentures. The Debentures are limited in aggregate principal amount as
specified in the Indenture.

         Because of the occurrence and continuation of a Special Event, in
certain circumstances, this Debenture may become due and payable at the
principal amount together with any interest accrued thereon (the "Redemption
Price"). The Redemption Price shall be paid prior to 12:00 noon, Eastern
Standard Time, time, on the date of such redemption or at such earlier time
as the Company determines. The Company shall have the right to redeem this
Debenture at the option of the Company, without premium or penalty, in whole
or in part at anytime on or after September 30, 2004 (an "Optional
Redemption"), or at any time in certain circumstances upon the occurrence of
a Special Event, at a Redemption Price equal to 100% of the principal amount
plus any accrued but unpaid interest, to the date of such redemption. Any
redemption pursuant to this paragraph shall be made upon not less than 30
days nor more than 60 days notice, at the Redemption Price. If the Debentures
are only partially redeemed by the Company pursuant to an Optional
Redemption, the Debentures shall be redeemed pro rata or by lot or by any
other method utilized by the Trustee. In the event of redemption of this
Debenture in part only, a new Debenture or Debentures for the unredeemed
portion hereof shall be issued in the name of the holder hereof upon the
cancellation hereof. In case an Event of Default, as defined in the
Indenture, shall have occurred and be continuing, the principal of all of the
Debentures may be declared, and upon such declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions
provided in the Indenture. The Indenture contains provisions permitting the
Company and the Trustee, with the consent of the holders of not less than a
majority in aggregate principal amount of the Debentures at the time
outstanding, as defined in the Indenture, to execute supplemental indentures
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or of modifying in any manner the rights of the holders of the
Debentures; provided, however, that no such supplemental indenture shall (i)
extend the fixed maturity of the Debentures except as provided in the
Indenture, or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, without the consent of the
holder of each Debenture so affected; or (ii) reduce the aforesaid percentage
of Debentures, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of each Debenture
then outstanding and affected thereby. The Indenture also contains provisions
permitting the holders of a majority in aggregate principal amount of the
Debentures at the time outstanding, on behalf of all of the holders of the
Debentures, to waive


                                       5


any past default in the performance of any of the covenants contained in the
Indenture, or established pursuant to the Indenture, and its consequences,
except a default in the payment of the principal of or interest on any of the
Debentures. Any such consent or waiver by the registered holder of this
Debenture (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders and owners of this
Debenture and of any Debenture issued in exchange herefor or in place hereof
(whether by registration of transfer or otherwise), irrespective of whether
or not any notation of such consent or waiver is made upon this Debenture. No
reference herein to the Indenture and no provision of this Debenture or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal and interest on this
Debenture at the time and place and at the rate and in the money herein
prescribed.

         Provided certain conditions are met, the Company shall have the
right at any time during the term of the Debentures and from time to time to
extend the interest payment period of such Debentures for up to 20
consecutive quarters (each, an "Extended Interest Payment Period"), at the
end of which period the Company shall pay all interest then accrued and
unpaid (together with interest thereon at the rate specified for the
Debentures to the extent that payment of such interest is enforceable under
applicable law). Before the termination of any such Extended Interest Payment
Period, so long as no Event of Default shall have occurred and be continuing,
the Company may further extend such Extended Interest Payment Period,
provided that such Extended Interest Payment Period together with all such
further extensions thereof shall not exceed 20 consecutive quarters, extend
beyond the Stated Maturity or end on a date other than an Interest Payment
Date. At the termination of any such Extended Interest Payment Period and
upon the payment of all accrued and unpaid interest and any additional
amounts then due and subject to the foregoing conditions, the Company may
commence a new Extended Interest Payment Period.

         As provided in the Indenture and subject to certain limitations
therein set forth, this Debenture is transferable by the registered holder
hereof on the Debenture Register of the Company, upon surrender of this
Debenture for registration of transfer at the office or agency of the Trustee
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company or the Trustee duly executed by the registered
holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Debentures of authorized denominations and for the same aggregate
principal amount shall be issued to the designated transferee or transferees.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in relation thereto.

         Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and the Debenture
Registrar may deem and treat the registered holder hereof as the absolute
owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone
other than the Debenture Registrar) for the purpose of receiving payment of
or on account of the principal hereof and interest due hereon and for all
other purposes, and neither the Company nor the Trustee nor any paying agent
nor any Debenture Registrar shall be affected by any notice to the contrary.


                                       6


         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether
by virtue of any constitution, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issuance hereof,
expressly waived and released.

         The Debentures are issuable only in registered form without coupons
in denominations of $25 and any integral multiple thereof.

         All terms used in this Debenture that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
