      Fixed/Floating Rate Junior Subordinated Deferrable Interest Debenture

                                       of

                       Exchange National Bancshares, Inc.

                                  March 17,2005

     Exchange National Bancshares, Inc., a Missouri corporation (the "Company"
which term includes any successor Person under the Indenture hereinafter
referred to), for value received promises to pay to Wilmington Trust Company,
not in its individual capacity but solely as Institutional Trustee for Exchange
National Statutory Trust II (the "Holder") or registered assigns, the principal
sum of twenty-three million seven hundred twelve thousand dollars
($23,712,000.00) on March 17, 2035, and to pay interest on said principal sum
from March 17, 2005, or from the most recent Interest Payment Date (as defined
below) to which interest has been paid or duly provided for, quarterly (subject
to deferral as set forth herein) in arrears on March 17, June 17, September 17
and December 17 of each year or if such day is not a Business Day, then the next
succeeding Business Day (each such date, an "Interest Payment Date") (it being
understood that interest accrues for any such non-Business Day), commencing on
the Interest Payment Date in June 2005, at an annual rate equal to 6.30%
beginning on (and including) the date of original issuance and ending on (but
excluding) the Interest Payment Date in March 2010 and at an annual rate for
each successive period beginning on (and including) the Interest Payment Date in
March 2010, and each succeeding Interest Payment Date, and ending on (but
excluding) the next succeeding Interest Payment Date (each a "Distribution
Period"), equal to 3-Month LIBOR, determined as described below, plus 1.83% (the
"Coupon Rate"), applied to the principal amount hereof, until the principal
hereof is paid or duly provided for or made available for payment, and on any
overdue principal and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest (including Additional Interest) at the Interest Rate in effect for each
applicable period, compounded quarterly, from the dates such amounts are due
until they are paid or made available for payment. The amount of interest
payable (i) for any Distribution Period commencing on or after the date of
original issuance but before the Interest Payment Date in March 2010 will be
computed

on the basis of a 360-day year of twelve 30-day months, and (ii) for the
Distribution Period commencing on or after the Interest Payment Date in March
2010 and each succeeding Distribution Period will be computed on the basis of
the actual number of days in the Distribution Period concerned divided by 360.
The interest installment so payable, and punctually paid or duly provided for,
on any Interest Payment Date will, as provided in the Indenture, be paid to the
Person in whose name this Debenture (or one or more Predecessor Securities) is
registered at the close of business on the regular record date for such interest
installment, which shall be fifteen Business Days prior to the day on which the
relevant Interest Payment Date occurs. Any such interest installment not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such regular record date and may be paid to the Person in whose name
this Debenture (or one or more Predecessor Securities) is registered at the
close of business on a special record date.

     "3-Month LIBOR" as used herein, means the London interbank offered interest
rate for three-month U.S. dollar deposits determined by the Trustee in the
following order of priority: (i) the rate (expressed as a percentage per annum)
for U.S. dollar deposits having a three-month maturity that appears on Telerate
Page 3750 as of 11:00 a.m. (London time) on the related Determination Date
("Telerate Page 3750" means the display designated as "Page 3750" on the
Moneyline Telerate Service or such other page as may replace Page 3750 on that
service or such other service or services as may be nominated by the British
Bankers' Association as the information vendor for the purpose of displaying
London interbank offered rates for U.S. dollar deposits); (ii) if such rate
cannot be identified on the related Determination Date, the Trustee will request
the principal London offices of four leading banks in the London interbank
market to provide such banks' offered quotations (expressed as percentages per
annum) to prime banks in the London interbank market for U.S. dollar deposits
having a three-month maturity as of 11:00 a.m. (London time) on such
Determination Date. If at least two quotations are provided, 3-Month LIBOR will
be the arithmetic mean of such quotations; (iii) if fewer than two such
quotations are provided as requested in clause (ii) above, the Trustee will
request four major New York City banks to provide such banks' offered quotations
(expressed as percentages per annum) to leading European banks for loans in U.S.
dollars as of 11:00 a.m. (London time) on such Determination Date. If at least
two such quotations are provided, 3-Month LIBOR will be the arithmetic mean of
such quotations; and (iv) if fewer than two such quotations are provided as
requested in clause (iii) above, 3-Month LIBOR will be a 3-Month LIBOR
determined with respect to the Distribution Period immediately preceding such
current Distribution Period. If the rate for U.S. dollar deposits having a
three-month maturity that initially appears on Telerate Page 3750 as of 11:00
a.m. (London time) on the related Determination Date is superseded on the
Telerate Page 3750 by a corrected rate by 12:00 noon (London time) on such
Determination Date, then the corrected rate as so substituted on the applicable
page will be the applicable 3-Month LIBOR for such Determination Date. As used
herein, "Determination Date" means the date that is two London Banking Days
(i.e., a business day in which dealings in deposits in U.S. dollars are
transacted in the London interbank market) preceding the commencement of the
relevant Distribution Period.

     The Interest Rate for any Distribution Period will at no time be higher
than the maximum rate then permitted by New York law as the same may be modified
by United States law.

     All percentages resulting from any calculations on the Debentures will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upward (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655), and all dollar
amounts used in or resulting from such calculation will be rounded to the
nearest cent (with one-half cent being rounded upward)).

     The principal of and interest on this Debenture shall be payable at the
office or agency of the Trustee (or other paying agent appointed by the Company)
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 by check mailed to the registered holder at such address
as shall appear in the Debenture Register if a request for a wire transfer by
such holder has not been received by the Company or by wire transfer to an
account appropriately designated by the holder hereof. Notwithstanding the
foregoing, so long as the holder of this Debenture is the Institutional Trustee,
the payment of the principal of and interest on this Debenture will be made in
immediately available funds at such place and to such account as may be
designated by the Trustee.

     So long as no Acceleration Event of Default has occurred and is continuing,
the Company shall have the right, from time to time, and without causing an
Event of Default, to defer payments of interest on the Debentures by extending
the interest payment period on the Debentures at any time and from time to time
during the term of the Debentures, for up to 20 consecutive quarterly periods
(each such extended interest payment period, an "Extension Period"), during
which Extension Period no interest (including Additional Interest) shall be due
and payable (except any Additional Sums that may be due and payable). No
Extension Period may end on a date other than an Interest Payment Date. During
an Extension Period, interest will continue to accrue on the Debentures, and
interest on such accrued interest will accrue at an annual rate equal to the
Interest Rate in effect for such Extension Period, compounded quarterly from the
date such interest would have been payable were it not for the Extension Period,
to the extent permitted by law (such interest referred to herein as "Additional
Interest"). At the end of any such Extension Period the Company shall pay all
interest then accrued and unpaid on the Debentures (together with Additional
Interest thereon); provided, however, that no Extension Period may extend beyond
the Maturity Date; provided further, however, that during any such Extension
Period, the Company shall not and shall not permit any Affiliate to engage in
any of the activities or transactions described on the reverse side hereof and
in the Indenture. Prior to the termination of any Extension Period, the Company
may further extend such period, provided that such period together with all such
previous and further consecutive extensions thereof shall not exceed 20
consecutive quarterly periods, or extend beyond the Maturity Date. Upon the
termination of any Extension Period and upon the payment of all accrued and
unpaid interest and Additional Interest, the Company may commence a new
Extension Period, subject to the foregoing requirements. No interest or
Additional Interest shall be due and payable during an Extension Period, except
at the end thereof, but each installment of interest that would otherwise have
been due and payable during such Extension Period shall bear Additional
Interest. The Company must give the Trustee notice of its election to begin or
extend an Extension Period by the close of business at least 15 Business Days
prior to the Interest Payment Date with respect to which interest on the
Debentures would have been payable except for the election to begin or extend
such Extension Period.

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

     This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
certificate of authentication hereon shall have been signed by or on behalf of
the Trustee.

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

     IN WITNESS WHEREOF, the Company has duly executed this certificate.

                                              ----------------------------------

                              REVERSE OF DEBENTURE

     This Debenture is one of the fixed/floating rate junior subordinated
deferrable interest debentures of the Company, all issued or to be issued under
and pursuant to the Indenture dated as of March 17, 2005 (the "Indenture"), duly
executed and delivered between the Company and 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.

     Upon the occurrence and continuation of a Special Event prior to the
Interest Payment Date in March 2010, the Company shall have the right to redeem
the Debentures in whole, but not in part, at any Interest Payment Date, within
120 days following the occurrence of such Special Event, at the Special
Redemption Price.

     In addition, the Company shall have the right to redeem the Debentures, in
whole or in part, but in all cases in a principal amount with integral multiples
of $1,000.00, on any Interest Payment Date on or after the Interest Payment
Date in March 2010, at the Redemption Price.

     Prior to 10:00 a.m. New York City time on the Redemption Date or Special
Redemption Date, as applicable, the Company will deposit with the Trustee or
with one or more paying agents an amount of money sufficient to redeem on the
Redemption Date or the Special Redemption Date, as applicable, all the
Debentures so called for redemption at the appropriate Redemption Price or
Special Redemption Price.

     If all, or less than all, the Debentures are to be redeemed, the Company
will give the Trustee notice not less than 45 nor more than 60 days,
respectively, prior to the Redemption Date or Special Redemption Date, as
applicable, as to the aggregate principal amount of Debentures to be redeemed
and the Trustee shall select, in such manner as in its sole discretion it shall
deem appropriate and fair, the Debentures or portions thereof (in integral
multiples of $1,000.00) to be redeemed.

     Notwithstanding the foregoing, any redemption of Debentures by the Company
shall be subject to the receipt of any and all required regulatory approvals.

     In case an Acceleration Event of Default shall have occurred and be
continuing, upon demand of the Trustee, the principal of all of the Debentures
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, to execute
supplemental indentures 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 the rights of the holders
of the Debentures; provided, however, that no such supplemental indenture shall
without the consent of the holders of each Debenture then outstanding and
affected thereby (i) change the fixed maturity of any Debenture, or reduce the
principal amount thereof or any premium thereon, or reduce the rate or extend
the time of payment of interest thereon, or reduce any amount payable on
redemption thereof or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than that provided in the
Debentures, or impair or affect the right of any Securityholder to institute
suit for payment thereof or impair the right of repayment, if any, at the option
of the holder, or (ii) reduce the aforesaid percentage of Debentures the holders
of which are required to consent to any such supplemental indenture.

     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 the holders of all of the Debentures to waive (or modify any
previously granted waiver of) any past default or Event of Default, and its
consequences, except a default (a) in the payment of principal of, premium, if
any, or interest on any of the Debentures, (b) in respect of covenants or
provisions hereof or of the Indenture which cannot be modified or amended
without the consent of the holder of each Debenture affected, or (c) in respect
of the covenants contained in Section 3.9 of the Indenture; provided, however,
that if the Debentures are held by the Trust or a trustee of such trust, such
waiver or modification to such waiver shall not be effective until the holders
of a majority in Liquidation Amount of Trust Securities of the Trust shall have
consented to such waiver or modification to such waiver, provided, further, that
if the consent of the holder of each outstanding Debenture is required, such
waiver shall not be effective until each holder of the Trust Securities of the
Trust shall have consented to such waiver. Upon any such waiver, the default
covered thereby shall be deemed to be cured for all purposes of the 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 Event of Default or impair
any right consequent thereon. Whenever any default or Event of Default hereunder
shall have been waived as permitted by the Indenture, said default or Event of
Default shall for all purposes of the Debentures and the Indenture be deemed to
have been cured and to be not continuing.

     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 of and premium, if any, and
interest, including Additional Interest, on this Debenture at the time and place
and at the rate and in the money herein prescribed.

     The Company has agreed that if Debentures are initially issued to the Trust
or a trustee of such Trust in connection with the issuance of Trust Securities
by the Trust (regardless of whether Debentures continue to be held by such
Trust) and (i) there shall have occurred and be continuing an Event of Default,
(ii) the Company shall be in default with respect to its payment of any
obligations under the Capital Securities Guarantee, or (iii) the Company shall
have given notice of its election to defer payments of interest on the
Debentures by extending the interest payment period as provided herein and such
Extension Period, or any extension thereof, shall be continuing, then the
Company shall not, and shall not allow any Affiliate of the Company to, (x)
declare or pay any dividends or distributions on, or redeem, purchase, acquire,
or make a liquidation payment with respect to, any of the Company's capital
stock or its Affiliates' capital stock (other than payments of dividends or
distributions to the Company) or make any guarantee payments with respect to the
foregoing or (y) make any payment of principal of or interest or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company or any
Affiliate that rank pari passu in all respects with or junior in interest to the
Debentures (other than, with respect to clauses (x) and (y) above, (1)
repurchases, redemptions or other acquisitions of

shares of capital stock of the Company in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
one or more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Company (or securities convertible into or
exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, if any, (2)
as a result of any exchange or conversion of any class or series of the
Company's capital stock (or any capital stock of a subsidiary of the Company)
for any class or series of the Company's capital stock or of any class or series
of the Company's indebtedness for any class or series of the Company's capital
stock, (3) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (4) any declaration of a
dividend in connection with any stockholders' rights plan, or the issuance of
rights, stock or other property under any stockholders' rights plan, or the
redemption or repurchase of rights pursuant thereto, (5) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock and any cash payments in lieu of fractional shares
issued in connection therewith, or (6) payments under the Capital Securities
Guarantee).

     The Debentures are issuable only in registered, certificated form without
coupons and in minimum denominations of $100,000.00 and any multiple of
$1,000.00 in excess thereof. As provided in the Indenture and subject to the
transfer restrictions and limitations as may be contained herein and therein
from time to time, this Debenture is transferable by the holder hereof on the
Debenture Register of the Company. Upon due presentment for registration of
transfer of any Debenture at the Principal Office of the Trustee or at any
office or agency of the Company maintained for such purpose as provided in
Section 3.2 of the Indenture, the Company shall execute, the Company or the
Trustee shall register and the Trustee or the Authenticating Agent shall
authenticate and make available for delivery in the name of the transferee or
transferees a new Debenture for a like aggregate principal amount. All
Debentures presented for registration of transfer or for exchange or payment
shall (if so required by the Company or the Trustee or the Authenticating Agent)
be duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to, the Company and the Trustee or the
Authenticating Agent duly executed by the holder or his attorney duly authorized
in writing. No service charge shall be made for any exchange or registration of
transfer of Debentures, but the Company or the Trustee may require payment of a
sum sufficient to cover any tax, fee or other governmental charge that may be
imposed in connection therewith.

     Prior to due presentment for registration of transfer of any Debenture, the
Company, the Trustee, any Authenticating Agent, any paying agent, any transfer
agent and any Debenture registrar may deem the Person in whose name such
Debenture shall be registered upon the Debenture Register to be, and may treat
him as, the absolute owner of such Debenture (whether or not such Debenture
shall be overdue) for the purpose of receiving payment of or on account of the
principal of, premium, if any, and interest on such Debenture and for all other
purposes; and neither the Company nor the Trustee nor any Authenticating Agent
nor any paying agent nor any transfer agent nor any Debenture registrar shall be
affected by any notice to the contrary. All such payments so made to any holder
for the time being or upon his order shall be valid, and, to the extent of the
sum or sums so paid, effectual to satisfy and discharge the liability for moneys
payable upon any such Debenture.

     No recourse for the payment of the principal of or premium, if any, or
interest on any Debenture, or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture or in any supplemental indenture, or
in any such Debenture, or because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, stockholder,
employee, officer or director, as such, past, present or future, of the Company
or of any successor Person of the Company, either directly or through the
Company or any successor Person of the Company, 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 all such liability is
hereby expressly waived and released as a condition of, and as a consideration
for, the execution of the Indenture and the issue of the Debentures.

     Capitalized terms used and not defined in this Debenture shall have the
meanings assigned in the Indenture dated as of the date of original issuance of
this Debenture between the Trustee and the Company.

     THE INDENTURE AND THE DEBENTURES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF
LAW PRINCIPLES THEREOF.
