                                    ARTICLE I

                                   DEFINITIONS

         Section 1.1. Definitions of Terms. The terms defined in this Section
1.1 (except as in this Indenture otherwise expressly provided or unless the
context otherwise requires) for all purposes of this Indenture and of any
indenture supplemental hereto shall have the respective meanings specified in
this Section 1.1 and shall include the plural as well as the singular. All other
terms used in this Indenture that are defined in the Trust Indenture Act, or
that are by reference in the Trust Indenture Act defined in the Securities Act
(except as herein otherwise expressly provided or unless the context otherwise
requires), shall have the meanings assigned to such terms in the Trust Indenture
Act and in the Securities Act as in force at the date of the execution of this
instrument. All accounting terms used herein and not expressly defined shall
have the meanings assigned to such terms in accordance with Generally Accepted
Accounting Principles.

         "Accelerated Maturity Date" means if the Company elects to accelerate

or other securities that are intended to qualify for Tier 1 capital treatment
(or the then equivalent thereof) for purposes of the capital adequacy guidelines
of the Federal Reserve, as then in effect and applicable to the Company, other
than the Debentures; provided, however, that the inability of the Company to
treat all or any portion of the Additional Junior Indebtedness as Tier 1 capital
shall not disqualify it as Additional Junior Indebtedness if such inability
results from the Company having cumulative preferred stock, minority interests
in consolidated subsidiaries, or any other class of security or interest which
the Federal Reserve now or may hereafter accord Tier 1 capital treatment
(including the Debentures) in excess of the amount which may qualify for
treatment as Tier 1 capital under applicable capital adequacy guidelines of the
Federal Reserve, (b) that is junior or otherwise subordinate in right of payment
to Senior Indebtedness of the Company, and (c) that has a maturity or is
otherwise due and payable by the Company on a date twelve (12) months or more
after its date of original issuance, other than the Debentures.

         "Additional Payments" shall have the meaning set forth in Section
2.5(c).

         "Additional Senior Obligations" means all indebtedness of the Company
whether incurred on or prior to the date of this Indenture or thereafter

respect of Senior Debt or Subordinated Debt or obligations which, by their


                                      -2-
<PAGE>   9


terms, are expressly stated to be not superior in right of payment to the
Debentures or to rank pari passu in right of payment with the Debentures. For
purposes of this definition, "claim" shall have the meaning assigned thereto in
Section 101(4) of the United States Bankruptcy Code of 1978, as amended.

         "Administrative Trustees" shall have the meaning set forth in the Trust
Agreement.

         "Affiliate" means, with respect to a specified Person, (a) any Person
directly or indirectly owning, controlling or holding with power to vote 10% or
more of the outstanding voting securities or other ownership interests of the
specified Person; (b) any Person 10% or more of whose outstanding voting

Treasurer, and the Trustee in accordance with such written order shall
authenticate and deliver such Debentures.

         (d) In authenticating such Debentures and accepting the additional
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.


                                      -12-

         (e) 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 the State of 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 $10, 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.

         (b) The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in the State of 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 the Debenture Registrar (as defined
below) 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, Section 3.5(b) 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.


                                      -13-
<PAGE>   20


         (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 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 authenticated 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 shall authenticate any such substituted Debenture and deliver the same
upon the written request or authorization of the Chief Executive Officer,
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.


                                      -14-
<PAGE>   21


         (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.

         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 the 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 the 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 Authenticating Agent 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


                                      -15-
<PAGE>   22


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 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) but 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
180 days following the occurrence of such Special Event (the "180-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 180-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, and, provided further, that the Company shall have no
right to redeem the Debentures pursuant to this Section 3.2 while it is pursuing
any Ministerial Action pursuant to its obligations hereunder, and, provided
further, that, if it is determined that the taking of a Ministerial Action would
not eliminate the Tax Event within the 180 Day Period, the Company's right to
redeem the Debentures pursuant to this Section 3.2 shall be restored and it
shall have no further obligations to pursue the Ministerial Action. 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.


                                      -16-
<PAGE>   23


         Section 3.3. Optional Redemption by the Company. (a) Subject to the
provisions of Section 3.3(c), 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 _________, 2006, 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(a), 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 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) Subject to the provisions of Section 3.3(c), the Company shall have
the right to redeem Debentures at any time and from time to time in a principal
amount equal to the Liquidation Amount (as defined in the Trust Agreement) of
any Preferred Securities purchased and beneficially owned by the Company, plus
an additional principal amount of Debentures equal to the Liquidation Amount (as
defined in the Trust Agreement) of that number of Common Securities that bears
the same proportion to the total number of Common Securities then outstanding as
the number of Preferred Securities to be redeemed bears to the total number of
Preferred Securities then outstanding. Such Debentures shall be redeemed
pursuant to this Section 3.3(b) only in exchange for and upon surrender by the
Company to the Property Trustee of the Preferred Securities and a proportionate
amount of Common Securities, whereupon the Property Trustee shall cancel the
Preferred Securities and Common Securities so surrendered and a Like Amount (as
defined in the Trust Agreement) of Debentures shall be extinguished by the
Trustee and shall no longer be deemed Outstanding.

         (c) If a partial redemption of the Debentures would result in the
exclusion of the Preferred Securities issued by the Trust from the Nasdaq
National Market or the delisting or exclusion of the Preferred Securities from
any national securities exchange or other organization on which the Preferred
Securities are then listed or quoted, 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) Except in the case of a
redemption pursuant to Section 3.3(b), 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 Preferred Securities as described in Section 3.3(c) 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


                                      -17-
<PAGE>   24


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 in the
State of Delaware 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) Except in the case of a redemption pursuant to Section 3.3(b), if
less than all the Debentures are to be redeemed, the Company shall give the
Trustee at least 45 days' written 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 $10 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 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 Chief Executive Officer, 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


                                      -18-
<PAGE>   25


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. So long as no Event
of Default has occurred and is continuing, the Company shall have the right, at
any time and from time to time during the term of the Debentures, to defer
payments of interest by extending the interest payment period of such Debentures
for a period not exceeding 20 consecutive quarters (the "Extension Period"),
during which Extension Period no interest shall be due and payable; provided
that no Extension 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
Extension Period ("Compounded Interest"). At the end of the Extension 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
Payments and Compounded Interest (together, "Deferred Payments") 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 Extension Period. Before the termination of any Extension 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 Extension Period and upon the
payment of all Deferred Payments then due, the Company may commence a new
Extension Period, subject to the foregoing requirements. No interest shall be
due and payable during an Extension Period, except at the end thereof, but the
Company may prepay at any time all or any portion of the interest accrued during
an Extension 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
Extension Period, the Company shall give written notice to the Administrative
Trustees, the Property Trustee and the Trustee of its selection of such
Extension 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;


                                      -19-
<PAGE>   26


or (ii) the date the Trust is required to give notice of the record date, or the
date such Distributions are payable, to the Nasdaq National Market or other
applicable self-regulatory organization or to holders of the Preferred
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 Extension Period, the Company shall give the
holders of the Debentures and the Trustee written notice of its selection of
such Extension 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
Nasdaq National Market 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 Extension Period permitted under Section 4.1.

         Section 4.3. Limitation on Transactions. If (a) the Company shall
exercise its right to defer payment of interest as provided in Section 4.1; or
(b) there shall have occurred any Event of Default, then (i) neither the Company
nor any of its Subsidiaries shall 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 (A)
dividends or distributions in common stock of the Company or such Subsidiary, as
the case may be, or any declaration of a non-cash dividend in connection with
the implementation of a shareholder rights plan, or the issuance of stock under
any such plan in the future, or the redemption or repurchase of any such rights
pursuant thereto, (B) purchases of common stock of the Company related to the
rights under any of the Company's benefit plans for its directors, officers or
employees, (C) as a result of a reclassification of its capital stock for
another class of its capital stock or (D) dividends payable by such Subsidiary
to the Company or any of its Subsidiaries); (ii) the Company shall not 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 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 to the Debentures; provided,
however, that notwithstanding the foregoing the Company may make payments
pursuant to its obligations under the Preferred Securities Guarantee; and (iii)
the Company shall not redeem, purchase or acquire less than all of the
Outstanding Debentures or any of the Preferred 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. Each such
payment of the principal of and interest on the Debentures shall relate only to
the Debentures, shall not be combined with any other payment of


                                      -20-
<PAGE>   27


the principal of or interest on any other obligation of the Company, and shall
be clearly and unmistakably identified as pertaining to the Debentures.

         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 the State of Delaware and at such other location or
locations as may be designated as provided in this Section 5.2, where (a)
Debentures may be presented for payment; (b) Debentures may be presented as
hereinabove authorized for registration of transfer and exchange; and (c)
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 a 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 the State of Delaware 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 the State of 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 Trustee 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 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, upon the
         written request of the Trustee, forthwith pay to the Trustee all sums
         so held in trust by such Paying Agent; and

                 (iv) that it shall perform all other duties of Paying Agent as
         set forth in this Indenture.


                                      -21-
<PAGE>   28


         (b) If the Company shall act as its own Paying Agent with respect to
the Debentures, it shall on or before each due date of the principal of or
interest on such Debentures, set aside, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay such principal
or interest so becoming due on Debentures until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and shall promptly notify
the Trustee of such action, or any failure (by it or any other obligor on such
Debentures) to take such action. Whenever the Company shall have one or more
Paying Agents for the Debentures, it shall, prior to each due date of the
principal of or interest on any Debentures, deposit with the Paying Agent a sum
sufficient to pay the principal or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal or interest,
and (unless such Paying Agent is the Trustee) the Company shall promptly notify
the Trustee of this action or failure so to act.

         (c) Notwithstanding anything in this Section 5.3 to the contrary, (i)
the agreement to hold sums in trust as provided in this Section 5.3 is subject
to the provisions of Section 13.3 and 13.4; and (ii) the Company may at any
time, for the purpose of obtaining the satisfaction and discharge of this
Indenture or for any other purpose, pay, or direct any Paying Agent to pay, to
the Trustee all sums held in trust by the Company or such Paying Agent, such
sums to be held by the Trustee upon the same terms 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 the Trustee. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
shall appoint, in the manner provided in Section 9.11, a Trustee, so that there
shall at all times be a Trustee hereunder.

         Section 5.5. Compliance with Consolidation Provisions. The Company
shall not, while any of the Debentures remain Outstanding, consolidate with, or
merge into, or merge into itself, or sell or convey all or substantially all of
its property to any other company unless the provisions of Article XII hereof
are complied with.

         Section 5.6. Limitation on Transactions. If Debentures are issued to
the Trust or a trustee of the Trust in connection with the issuance of Trust
Securities by the Trust and (a) there shall have occurred an Event of Default;
(b) the Company shall be in default with respect to its payment of any
obligations under the Preferred Securities Guarantee relating to the Trust; or
(c) if the Company shall have given notice of its election to defer payments of
interest on such Debentures by extending the interest payment period as provided
in this Indenture and such Extension Period, or any extension thereof, shall be
continuing, then (i) neither the Company nor any of its Subsidiaries shall
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 (A) dividends or distributions in common stock of
the Company or such Subsidiary, as the case may be, or any declaration of a
non-cash dividend in connection with the implementation of a shareholder rights
plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (B) purchases of
common stock of the Company related to the rights under any of the Company's
benefit plans for its directors, officers or employees, (C) as a result of a
reclassification of its capital stock or


                                      -22-
<PAGE>   29


(D) dividends payable by such Subsidiary to the Company or any of its
Subsidiaries); (ii) the Company shall not make any payment of principal,
interest or premium, if any, or repay, repurchase or redeem any debt securities
issued by the Company which rank pari passu with or junior in interest to the
Debentures; provided, however, that the Company may make payments pursuant to
its obligations under the Preferred Securities Guarantee; and (iii) the Company
shall not redeem, purchase or acquire less than all of the Outstanding
Debentures or any of the Preferred Securities.

         Section 5.7. Covenants as to the Trust. For so long as the Trust
Securities of the Trust remain outstanding, the Company (a) shall maintain 100%
direct or indirect ownership of the Common Securities of the Trust; provided,
however, that any permitted successor of the Company under this Indenture may
succeed to the Company's ownership of the Common Securities; (b) shall not
voluntarily terminate, wind up or liquidate the Trust, except upon prior
approval of the Federal Reserve if then so required under applicable capital
guidelines, policies or regulations of the Federal Reserve; (c) shall use its
reasonable efforts to cause the Trust (i) to remain a business trust (and to
avoid involuntary 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 (ii) to otherwise continue not to be
treated as an association taxable as a corporation or partnership for United
States federal income tax purposes; (d) shall use its reasonable efforts to
cause each holder of Trust Securities to be treated as owning an individual
beneficial interest in the Debentures; and (e) any successor to the Company,
shall use reasonable efforts to maintain the eligibility of the Preferred
Securities for quotation or listing on any national securities exchange or other
organization on which the Preferred Securities are then quoted or listed
(including, if applicable, the Nasdaq National Market) and shall use reasonable
efforts to keep the Preferred Securities so quoted or listed for so long as the
Preferred Securities remain outstanding. In connection with the distribution of
the Debentures to the holders of the Preferred Securities issued by the Trust
upon a Dissolution Event, the Company shall use its best efforts to list such
Debentures on the Nasdaq National Market or on such other exchange as the
Preferred Securities are then listed.

         Section 5.8. Covenants as to Purchases. Except upon the exercise by the
Company of its right to redeem the Debentures pursuant to Section 3.2 upon the
occurrence and continuation of a Special Event, the Company shall not purchase
any Debentures, in whole or in part, from the Trust prior to ____________, 2006.

         Section 5.9. Waiver of Usury, Stay or Extension Laws. The Company shall
not at any time insist upon, or plead, or in any manner whatsoever claim or take
the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performances of this Indenture, and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

         interest upon any of the Debentures, as and when the same shall become
         due and payable, and continuance of such default for a period of 30
         days; provided, however, that a valid 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 Debentures as and when the same shall become due and payable
         whether at maturity, upon redemption, by declaration or otherwise;

                 (iii) the Company fails to observe or perform any other of its
         covenants or agreements with respect to the Debentures for a period of
         90 days after the date on which


                                      -25-
<PAGE>   32


         written notice of such failure, requiring the same to be remedied and
         stating that such notice is a "Notice of Default" hereunder, shall have
         been given to the Company by the Trustee, by registered or certified
         mail, or to the Company and the Trustee by the holders of at least 25%
         in principal amount of the Debentures at the time Outstanding;

         substantially all of its property; or (D) makes a general assignment
         for the benefit of its creditors;

                  (v) a court of competent jurisdiction enters an order under
         any Bankruptcy Law that (A) is for relief against the Company in an
         involuntary case; (B) appoints a Custodian of the Company for all or
         substantially all of its property; or (C) orders the liquidation of the
         Company, and the order or decree remains unstayed and in effect for 90
         days; or

                  (vi) the Trust shall have voluntarily or involuntarily
         dissolved, wound-up its business or otherwise terminated its existence
         except in connection with (A) the distribution of Debentures to holders

         the redemption of all of the outstanding Trust Securities of the Trust;
         or (C) certain mergers, consolidations or amalgamations, each as
         permitted by the Trust Agreement.

         (b) In each and every such case referred to in items (i) through (vi)
of Section 7.1(a), unless the principal of all the Debentures shall have already
become due and payable, either the Trustee or the holders of not less than 25%
in aggregate principal amount of the Debentures then Outstanding hereunder, by
notice in writing to the Company (and to the Trustee if given by such
Debentureholders) may declare the principal of all the Debentures to be due and
payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, notwithstanding anything contained in this
Indenture or in the Debentures.

         (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 money 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 principal of any and
all Debentures that shall have become due otherwise than by acceleration (with
interest upon such principal, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Debentures to the date of such payment or
deposit) and the amount payable to the Trustee under Section 9.7; 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 their terms, shall
have been remedied or waived as provided in Section 7.6. No such


                                      -26-
<PAGE>   33


rescission and annulment shall 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
the Trustee. (a) The Company covenants that (i) in case it shall default in the
payment of any installment of interest on any of the Debentures, and such
default shall have continued for a period of 30 days; or (ii) in case 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 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 set forth in Section
7.2(a) 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 money 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, the Trust, or the creditors or property of either, the
Trustee shall have power to intervene in such proceedings and take any action
therein that may be permitted by the court and shall (except 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 have the claims of the
Trustee and of the holders of the Debentures allowed for the entire amount due
and payable by the Company under this Indenture at 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 money or other
property payable or deliverable on any such claim, and to distribute the same
after the deduction of the amount payable to the Trustee under Section 9.7; and
any receiver,


                                      -27-
<PAGE>   34


assignee or trustee in 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.

         (d) All rights of action and of asserting claims under this Indenture,
or under any of the terms established with respect to the Debentures, may be
enforced by the Trustee without the possession of any of such Debentures, or the
production thereof at any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for 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 which is continuing, 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. Nothing contained herein
shall be deemed to authorize the Trustee to 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 proceeding.

         Section 7.3. Application of Money Collected. Any money or other assets
collected by the Trustee pursuant to this Article VII with respect to the
Debentures shall be applied in the following order, at the date or dates fixed
by the Trustee and, in case of the distribution of such money or other assets on
account of principal or interest, upon presentation of the Debentures, and
notation thereon of the payment, if only partially paid, and upon surrender
thereof if fully paid:

                  FIRST: To the payment of costs and expenses of collection and
         of all amounts payable to the Trustee under Section 9.7;

                  SECTION: To the payment of all Senior Indebtedness if and to
         the extent required by Article XVI; and

                  THIRD: To the payment of the amounts then due and unpaid upon
         the Debentures for principal and interest, in respect of which or for
         the benefit of which such money has been collected, ratably, without
         preference or priority of any kind, according to the amounts due and
         payable on such Debentures for principal and interest, respectively.

         Section 7.4. Limitation on Suits. (a) Except as set forth in this
Indenture, no holder of any Debenture shall have any right by virtue or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless (i) such holder previously shall have given to the Trustee
written notice of an Event of


                                      -28-
<PAGE>   35


Default and of the continuance thereof with respect to the Debentures specifying
such Event of Default, as hereinbefore provided; (ii) the holders of not less
than 25% in aggregate principal amount of the Debentures then Outstanding shall
have made written request upon the Trustee to institute such action, suit or
proceeding in its own name as trustee hereunder; (iii) such holder or holders
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby;
and (iv) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity shall have failed to institute any such action, suit or
proceeding and during such 60 day period, the holders of a majority in principal
amount of the Debentures do not give the Trustee a direction inconsistent with
the request.

         (b) Notwithstanding anything contained herein to the contrary or any
other provisions of this Indenture, the right of any holder of the Debentures to
receive payment of the principal of and interest on the Debentures, as therein
provided, on or after the respective due dates expressed in such Debenture (or
in the case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and
by accepting a Debenture hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Debenture with every other such
taker and holder and the Trustee that no one or more holders of the Debentures
shall have any right in any manner whatsoever by virtue or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of the
holders of any other of such Debentures, or to obtain or seek to obtain priority
over or preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of the Debentures. For the protection and
enforcement of the provisions of this Section 7.4, each and every
Debentureholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

         Section 7.5. Rights and Remedies Cumulative; Delay or Omission not
Waiver. (a) Except as otherwise provided in Section 2.9(b), all powers and
remedies given by this Article VII to the Trustee or to the Debentureholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of
any other powers and remedies available to the Trustee or the holders of the
Debentures, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Debentures.

         (b) No delay or omission of the Trustee or of any holder of any of the
Debentures to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 7.4, every power and remedy
given by this Article VII or by law to the Trustee or the Debentureholders may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Debentureholders.

         Section 7.6. Control by the Debentureholders. The holders of a majority
in aggregate principal amount of the Debentures at the time Outstanding,
determined in accordance with Section 10.4, shall have the right to direct the
time, method and place of conducting any


                                      -29-

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 principal and interest 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 Debentures are
held by the Trust or a trustee of the Trust, and 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 the
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 the Debentureholders holding more
than 10% in aggregate principal amount of the Outstanding Debentures, or to any
suit instituted by any 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 an Interest Payment Date or Maturity Date, as applicable, then a holder of
Preferred 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


                                      -30-
<PAGE>   37


Preferred Securities of such holders (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 actually made by the Company to such
holder of the Preferred Securities with respect to such Direct Action.

                    FORM OF THE DEBENTURE AND ORIGINAL ISSUE

Certificate of Authentication to be endorsed thereon are to be substantially in
the forms contained as Exhibit A to this Indenture, attached hereto and
incorporated herein by reference.

         Section 8.2. Original Issue of the Debentures. Debentures in the
aggregate principal amount of $__________ may, upon execution of this Indenture,
be executed by the Company and delivered to the Trustee for authentication. If
the Underwriters exercise their Option and there is an Option Closing Date (as
such terms are defined in the Underwriting Agreement, dated _________, 2001, by

                                   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 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 its exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her 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:


                                      -31-
<PAGE>   38


                            (A) 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

                            (B) in the absence of bad faith on the part of the
                  Trustee, the Trustee may with respect to the Debentures and
                  this Indenture 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 provisions hereof are specifically required to be
                  furnished to the Trustee, the Trustee shall be under a duty to
                  examine the same to determine whether or not they conform to
                  the requirements of this Indenture;

                  (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.

         Section 9.2. Notice of Defaults. Within 90 days after actual knowledge
by a Responsible Officer of the Trustee of the occurrence of any Default
hereunder with respect to the 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 of a Default in the
payment of the principal or interest (including any Additional Payments) 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.

         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 aggregate 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, upon the occurrence of an Event of Default (that is
         continuing and has not been cured or waived) to exercise with respect
         to the Debentures and this Indenture such of the rights and powers
         vested in it by this Indenture, and to use the same degree of care and
         skill in its exercise, as a prudent person would exercise or use under
         the circumstances in the conduct of his or her 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 so to do 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


                                      -33-
<PAGE>   40


         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, and 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. The 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 money paid over by the Trustee in accordance
with any provision of this Indenture, or for the use or application of any money
received by any Paying Agent other than the Trustee.

         Section 9.5. May Hold the Debentures. The Trustee or any Paying Agent
or Debenture Registrar for the Debentures, in its individual or any other
capacity, may become the owner or pledgee of the Debentures with the same rights
it would have if it were not Trustee, Paying Agent or Debenture Registrar.

         Section 9.6. Money Held in Trust. Subject to the provisions of Section
13.5, all money 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 money 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
reasonable 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.


                                      -34-
<PAGE>   41


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 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 Indenture, 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.

         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 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


                                      -35-
<PAGE>   42


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 Sections 9.9 and 9.10, on behalf of himself or herself 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:

                  (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

                  (iii) 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 9.10, 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 the Debentures may not remove the Trustee.

         (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.


                                      -36-
<PAGE>   43


         (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 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


                                      -37-

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 the 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
(6) months after the record date.

         Section 10.2. Proof of Execution by the 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 such
Debentureholder's 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.


                                      -38-
<PAGE>   45


         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
the 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 (a) 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; and (b) for purposes of this Section 10.4, the Trust shall be
deemed not to be controlled by the Company. 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 the 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.

                                   ARTICLE XI

                             SUPPLEMENTAL INDENTURES

         Section 11.1. Supplemental Indentures without the Consent of the
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, or
         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, 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;

                  (h) to qualify or maintain the qualification of this Indenture
         under the Trust Indenture Act; or

                  (i) to evidence a consolidation or merger involving the
         Company as permitted under Section 12.1.

         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


                                      -40-
<PAGE>   47


holders of any of the Debentures at the time Outstanding, notwithstanding any of
the provisions of Section 11.2.

         Section 11.2. Supplemental Indentures with Consent of the
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, (a) 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; or (b) 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 Debentures are held by the Trust or a trustee of
the Trust and 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. The Debentures Affected by Supplemental Indentures. The
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 exchanges or automated quotation system
upon which the Debentures may be listed or quoted, 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.

         Section 11.5. Execution of Supplemental Indentures. (a) Upon the
request of the Company, accompanied by its Board Resolutions authorizing the
execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of the 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 Sections 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.

         Section 11.6. Preservation of Registered Debentures. No supplemental
indenture shall be entered into which alters the form of Debentures from
registered to coupon form without an Opinion of Counsel stating that such
alteration will not result in adverse federal income tax consequences to the
Company.

                                   ARTICLE XII

                              SUCCESSOR CORPORATION

         Section 12.1. The 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, that the Company hereby
covenants and agrees that (a) 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


                                      -42-
<PAGE>   49


acquired such property; (b) in case the Company consolidates with or merges into
another Person or conveys or transfers its properties and assets substantially
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 (c)
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.

         (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.

                                  ARTICLE XIII

                           SATISFACTION AND DISCHARGE

         Section 13.1. Satisfaction and Discharge of Indenture. If at any time:

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 all 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 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 money or Governmental Obligations sufficient, or a
combination thereof sufficient, in the opinion of a


                                      -43-
<PAGE>   50


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, 9.7 and
9.10, 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 instruments acknowledging
satisfaction of and discharging this Indenture.

         Section 13.2. Discharge of Obligations. If at any time all Debentures
not heretofore delivered to the Trustee for cancellation or that have not become
due and payable as described in Section 13.1 shall have been paid by the Company
by depositing irrevocably with the Trustee as trust funds money 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 money 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, that shall survive until such Debentures
shall mature and be paid. Thereafter, Sections 9.7 and 13.5 shall survive.

         Section 13.3. Deposited Money to be Held in Trust. All money or
Governmental Obligations deposited with the Trustee pursuant to Sections 13.1 or
13.2 shall be held in trust and shall be available for payment as due, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent), to the holders of the Debentures for the payment or redemption of
which such money or Governmental Obligations have been deposited with the
Trustee.

         Section 13.4. Payment of Money Held by Paying Agents. In connection
with the satisfaction and discharge of this Indenture, all money or Governmental
Obligations then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Company, be paid to the Trustee and thereupon such
Paying Agent shall be released from all further liability with respect to such
money or Governmental Obligations.

         Section 13.5. Repayment to the Company. Any money 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 ________ [30] of each year or (if then held
by the Company) shall be discharged from such trust; and thereupon the Paying
Agent and the Trustee


                                      -44-
<PAGE>   51


shall be released from all further liability with respect to such money 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.

         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

         Section 14.1. No Recourse. No recourse under or upon any obligation,
covenant or agreement of this Indenture, or of the Debentures, or for any claim

such, of the Company or of any predecessor or successor corporation, either
directly or through the Company or any such 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; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations, and that no such personal liability whatever, shall
attach to, or is or shall be incurred by, the incorporators, stockholders,
officers or directors as such, of the Company or of any predecessor or successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debentures or implied therefrom;
and that any and all such personal liability of every name and nature, either at
common law or in equity or by constitution or statute, and any and all such
rights and claims against, every such incorporator, stockholder, officer or
director as such, because of the creation of the indebtedness hereby authorized,
or under or by reason of the obligations, covenants or agreements contained in
this Indenture or in any of the Debentures or implied therefrom, are hereby
expressly waived and released as a condition of, and as a consideration for, the
execution of this Indenture and the issuance of such Debentures.


                                   ARTICLE XV


                            MISCELLANEOUS PROVISIONS

         Section 15.1. Effect on Successors and Assigns. All the covenants,
stipulations, promises and agreements in this Indenture contained by or on
behalf of the Company shall bind its respective successors and assigns, whether
so expressed or not.

         Section 15.2. Actions by Successor. Any act or proceeding by any
provision of this Indenture authorized or required to be done or performed by
any board, committee or officer of the Company shall and may be done and
performed with like force and effect by the corresponding board, committee or
officer of any corporation that shall at the time be the lawful sole successor
of the Company.

         Section 15.3. Surrender of the Company Powers. The Company by
instrument in writing executed by appropriate authority of its Board of
Directors and delivered to the Trustee may


                                      -45-
<PAGE>   52


surrender any of the powers reserved to the Company, and thereupon such power so
surrendered shall terminate both as to the Company, as the case may be, and as
to any successor corporation.

         Section 15.4. Notices. Except as otherwise expressly provided herein
any notice or demand that by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the holders of Debentures
to or on the Company may be given or served by being deposited first class
postage prepaid in a post-office letterbox addressed (until another address is
filed in writing by the Company with the Trustee), as follows: c/o Team
Financial, Inc., 8 West Peoria, Paola, Kansas 66071, Attention: Chief Executive
Officer. Any notice, election, request or demand by the Company or any

Trust Office of the Trustee.

         Section 15.5. Governing Law. This Indenture and each Debenture shall be
deemed to be a contract made under the internal laws of the State of Kansas and
for all purposes shall be construed in accordance with the laws of said State.

         Section 15.6. Treatment of the Debentures as Debt. It is intended that
the Debentures shall be treated as indebtedness and not as equity for federal
income tax purposes. The provisions of this Indenture shall be interpreted to
further this intention. The Company (with respect to its separate books and
records), the Trustee and, by acceptance of a Debenture, each holder of a
Debenture, agree to treat the Debentures as indebtedness of the Company and not
as equity for all tax (including without limitation, federal income tax) and
financial accounting purposes.

         Section 15.7. Compliance Certificates and Opinions. (a) Upon any
application or demand by the Company to the Trustee to take any action under any
of the provisions of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate stating that all conditions precedent provided for in this
Indenture relating to the proposed action have been complied with and an Opinion
of Counsel stating that in the opinion of such counsel all such conditions
precedent have been complied with, except that in the case of any such
application or demand as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or demand, no additional certificate or opinion need be
furnished.

         (b) Each certificate or opinion of the Company provided for in this
Indenture and delivered to the Trustee with respect to compliance with a
condition or covenant in this Indenture shall include (i) a statement that the
Person making such certificate or opinion has read such covenant or condition;
(ii) a brief statement as to the nature and scope of the examination or
investigation upon which the statements or opinions contained in such
certificate or opinion are based; (iii) a statement that, in the opinion of such
Person, he or she has made such examination or investigation as, in the opinion
of such Person, is necessary to enable him or her to express an informed opinion
as to whether or not such covenant or condition has been complied with; and (iv)
a statement as to whether or not, in the opinion of such Person, such condition

         Section 15.8. Payments on Business Days. 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 (subject to Section 2.5(b)) 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.

         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; Right of Setoff. (a) 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 Preferred Securities may 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, and
notwithstanding the provisions of Section 7.4(a) hereof, if an Event of Default
has occurred and is continuing and such event is attributable to the failure of
the Company to pay principal or interest on the Debentures on the date such
principal or interest is otherwise payable (or in the case of redemption, on the
redemption date), the Company acknowledges that a holder of Preferred 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 Preferred Securities of such holder
on or after the respective due date specified in the Debentures.

         (b) Notwithstanding anything to the contrary contained in this
Indenture, the Company shall have the right to setoff any payment it is
otherwise required to make hereunder in respect of any Trust Securities to the
extent that the Company has previously made, or is concurrently


                                      -47-

making, a payment to the holder of such Trust Securities under the Preferred
Securities Guarantee or in connection with a proceeding for enforcement of
payment of the principal of or interest on the Debentures directly brought by
holders of any Trust Securities.

                                   ARTICLE XVI

                         SUBORDINATION OF THE DEBENTURES

         Section 16.1. Agreement to Subordinate. The Company covenants and
agrees, and each holder of the Debentures issued hereunder by such holder's
acceptance thereof likewise covenants and agrees, that all the 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 the 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 of the Company
(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. In no event shall the Debentures be subordinate to the
Company's: (i) trade accounts payable, (ii) accrued liabilities arising in the
ordinary course of business, or (iii) debt to any employee of the Company.

         Section 16.2. Default on Senior Indebtedness. 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, or in the
event that the maturity of any Senior Indebtedness 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 the 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 shall first be
paid in full, or payment thereof provided for in money in accordance with its
terms, before any


                                      -48-
<PAGE>   55


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 (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 the 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 is paid 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,
as their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Indebtedness, 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, 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, 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.

         (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), 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, 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. The 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 money 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 money 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 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 or herself to be a holder of Senior Indebtedness (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 the 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 Article XVI.

         (b) With respect to the holders of the Senior Indebtedness, 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


                                      -51-
<PAGE>   58


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 to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

         (b) Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the holders of the
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.

         Team Financial, Inc., a Kansas corporation (the "Company," which term

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 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 thereof shall be fixed by the
Trustee for the payment of such defaulted interest, notice thereof 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 or quotation system on or in which the
Debentures may be listed or quoted, 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 ___________ __, 2006, 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 (as defined in the Indenture). 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 by or on behalf of
the Trustee.

         The provisions of this Debenture are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

                         [Form of Reverse of Debenture]



                      ___% SUBORDINATED DEBENTURE DUE 2031
                                   (continued)

         This Debenture is one of the subordinated debentures of the Company
(herein sometimes referred to as the "Debentures"), all issued or to be issued
under and pursuant to an Indenture dated as of __________ __, 2001 (the
"Indenture") duly executed and delivered between the Company and Wilmington
Trust Company, 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 (as
defined in the Indenture), 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, on the date of such redemption or at such
earlier time as the Company determines. The Company shall have the right as set
forth in the Indenture to redeem this Debenture at the option of the Company,
without premium or penalty, in whole or in part at any time on or after
__________ __, 2006 (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 hereof plus any accrued but unpaid
interest hereon, 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. The Redemption Price shall be paid at the time
and in the manner provided therefor in the Indenture. 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 as described in the Indenture. In the event of an Optional
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, except as provided in the Indenture, (i) extend
the fixed maturity of the 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 thereby; or (ii) reduce the


                                      -5-
<PAGE>   66


aforesaid percentage of the Debentures, the holders of which are required to
consent to any such supplemental indenture, without the consent of the holder of
each Debenture then Outstanding and so 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 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.

         The Company, as further described in the Indenture, shall have the
right at any time during the term of the Debentures and from time to time to
defer payments of interest by extending the interest payment period of such
Debentures for up to 20 consecutive quarters (each, an "Extension Period"), at
the end of which period the Company shall pay all interest then accrued
(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 Extension Period, so long as no Event of
Default shall have occurred and be continuing, the Company may further extend
such Extension Period, provided that such Extension Period together with all
such further extensions thereof shall not exceed 20 consecutive quarters, extend
beyond __________ __, 2031, or end on a date other than an Interest Payment
Date. At the termination of any such Extension Period and upon the payment of
all Deferred Payments then due and subject to the foregoing conditions, the
Company may commence a new Extension 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 (as defined in the Indenture) 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 or her 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 (as defined in the
Indenture) and the Debenture Registrar may deem and treat the registered holder
hereof as the absolute owner hereof (whether or not this Debenture

                                      -6-
<PAGE>   67

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.

         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 $10 and any integral multiple thereof (or such other
denominations and any integral multiple thereof as may be deemed necessary by
the Company for the purpose of maintaining the eligibility of the Debentures for
listing on the Nasdaq National Market or any successor thereto).

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