and its financing subsidiary, Exchange National Statutory Trust II, a Delaware
statutory trust (the "Trust," and hereinafter together with the Company, the
"Offerors"), hereby confirm their agreement (this "Agreement") with you as

SECTION 1. ISSUANCE AND SALE OF SECURITIES.

     1.1. INTRODUCTION. The Offerors propose to issue and sell at the Closing

Capital Securities, with a liquidation amount of $1,000.00 per capital security
(the "Capital Securities"), to Preferred Term Securities XVII, Ltd., a company
with limited liability established under the laws of the Cayman Islands (the
"Purchaser") pursuant to the terms of a Subscription Agreement entered into, or
to be entered into on or prior to the Closing Date (as defined in Section 2.3.1
hereof), between the Offerors and the Purchaser (the "Subscription Agreement"),
the form of which is attached hereto as Exhibit A and incorporated herein by

     1.2. OPERATIVE AGREEMENTS. The Capital Securities shall be fully and
unconditionally guaranteed on a subordinated basis by the Company with respect
to distributions and amounts payable upon liquidation, redemption or repayment
(the "Guarantee") pursuant and subject to the Guarantee Agreement (the
"Guarantee Agreement"), to be dated as of the Closing Date and executed and
delivered by the Company and Wilmington Trust Company ("WTC"), as trustee (the
"Guarantee Trustee"), for the benefit from time to time of the holders of the
Capital Securities. The entire proceeds from the sale by the Trust to the
holders of the Capital Securities shall be combined with the entire proceeds
from the sale by
<PAGE>
the Trust to the Company of its common securities (the "Common Securities"), and
shall be used by the Trust to purchase $23,712,000.00 in principal amount of the
Fixed/Floating Rate Junior Subordinated Deferrable Interest Debentures (the
"Debentures") of the Company. The Capital Securities and the Common Securities
for the Trust shall be issued pursuant to an Amended and Restated Declaration of
Trust among WTC, as Delaware trustee (the "Delaware Trustee"), WTC, as
institutional trustee (the "Institutional Trustee"), the Administrators named
therein, and the Company, to be dated as of the Closing Date and in

Agreement"). The Debentures shall be issued pursuant to an Indenture (the
"Indenture"), to be dated as of the Closing Date, between the Company and WTC,

Section 1.2 and in Section 1.1 are referred to herein as the "Operative
Documents."

     1.3. RIGHTS OF PURCHASER. The Capital Securities shall be offered and sold
by the Trust directly to the Purchaser without registration of any of the
Capital Securities, the Debentures or the Guarantee under the Securities Act of
1933, as amended (the "Securities Act"), or any other applicable securities laws
in reliance upon exemptions from the registration requirements of the Securities
Act and other applicable securities laws. The Offerors agree that this Agreement
shall be incorporated by reference into the Subscription Agreement and the
Purchaser shall be entitled to each of the benefits of the Placement Agents and
the Purchaser under this Agreement and shall be entitled to enforce obligations
of the Offerors under this Agreement as fully as if the Purchaser were a party
to this Agreement. The Offerors and the Placement Agents have entered into this
Agreement to set forth their understanding as to their relationship and their
respective rights, duties and obligations.

     1.4. LEGENDS. Upon original issuance thereof, and until such time as the
same is no longer required under the applicable requirements of the Securities
Act, the Capital Securities and Debentures certificates shall each contain a
legend as required pursuant to any of the Operative Documents.

however, that in no event shall the Closing Date occur later than March 31, 2005
unless consented to by the Purchaser. Payment by the Purchaser shall be payable
in the manner set forth in the Subscription Agreement and shall be made prior to
or on the Closing Date.

          2.3.2. DELIVERY. The certificate for the Capital Securities shall be

this Agreement shall not have been fulfilled to the satisfaction of the
Placement Agents or if the Closing shall not have occurred on or before 10:00
a.m. (St. Louis time) on March 31, 2005, then each party hereto, notwithstanding
anything to the contrary in this Agreement, shall be relieved of all further
obligations under this Agreement without thereby waiving any rights it may have
by reason of such nonfulfillment or failure; provided, however, that the
obligations of the parties under Sections 2.4, 7.5 and 9 shall not be so
relieved and shall continue in full force and effect.

SECTION 3. CLOSING CONDITIONS. The obligations of the Purchaser and the
Placement Agents on the Closing Date shall be subject to the accuracy, at and as
of the Closing Date, of the representations and warranties of the Offerors
contained in this Agreement, to the accuracy, at and as of the Closing Date, of
the statements of the Offerors made in any certificates pursuant to this
Agreement, to the performance by the Offerors of their respective obligations
under this Agreement, to compliance, at and as of the Closing Date, by the
Offerors with their respective agreements herein contained, and to the following
further conditions:

     3.1. OPINIONS OF COUNSEL. On the Closing Date, the Placement Agents shall
have received the following favorable opinions, each dated as of the Closing
Date: (a) from Stinson Morrison Hecker LLP, counsel for the Offerors and
addressed to the Purchaser, the Placement Agents and WTC in substantially the
form set forth on Exhibit B-1 attached hereto and incorporated herein by this
reference, (b) from Richards, Layton & Finger, P.A., special Delaware counsel to
the Offerors and addressed to the Purchaser, the Placement Agents and the
Offerors, in substantially the form set forth on Exhibit B-2 attached hereto and
incorporated herein by this reference and (c) from Lewis, Rice & Fingersh, L.C.,
special tax counsel to the Offerors, and addressed to the Placement Agents and
the Offerors, in substantially the form set forth on Exhibit B-3 attached hereto
and incorporated herein by this reference, subject to the receipt by Lewis, Rice
& Fingersh, L.C. of a representation letter from the Company in the form set
forth in Exhibit B-3 completed in a manner reasonably satisfactory to Lewis,
Rice & Fingersh, L.C. (collectively, the "Offerors' Counsel Opinions"). In
rendering the Offerors' Counsel Opinions, counsel to the Offerors may rely as to
factual matters upon certificates or other documents furnished by officers,
directors and trustees of the Offerors (copies of which shall be delivered to
the Placement Agents and the Purchaser) and by government officials, and upon
such other documents as counsel to the Offerors may, in their reasonable
opinion, deem appropriate as a basis for the Offerors' Counsel Opinions. Counsel
to the Offerors may specify the jurisdictions in which they are admitted to
practice and that they are not admitted to practice in any other jurisdiction
and are not experts in the law of any other jurisdiction. If the Offerors'
counsel is not admitted to practice in the State of New York, the opinion of
Offerors' counsel may assume, for purposes of the opinion, that the laws of the
State of New York are substantively identical, in all respects material to the
opinion, to the internal laws of the state in which such counsel is admitted to
practice. Such Offerors' Counsel Opinions shall not state that they are to be
governed or qualified by, or that they are otherwise subject to, any treatise,
written policy or other


                                       3
<PAGE>
document relating to legal opinions, including, without limitation, the Legal

the Company, dated as of the Closing Date, stating that (i) the representations
and warranties of the Offerors set forth in Section 5 hereof are true and
correct as of the Closing Date and that the Offerors have complied with all
agreements and satisfied all conditions on their part to be performed or
satisfied at or prior to the Closing Date, (ii) since the date of this Agreement
the Offerors have not incurred any liability or obligation, direct or
contingent, or entered into any material transactions, other than in the
ordinary course of business, which is material to the Offerors, and (iii)
covering such other matters as the Placement Agents may reasonably request.

     3.3. ADMINISTRATOR'S CERTIFICATE. At the Closing Date, the Purchaser and
the Placement Agents shall have received a certificate of one or more
Administrators of the Trust, dated as of the Closing Date, stating that the
representations and warranties of the Trust set forth in Section 5 are true and

agreements and satisfied all conditions on its part to be performed or satisfied
at or prior to the Closing Date.

     3.4. PURCHASE PERMITTED BY APPLICABLE LAWS; LEGAL INVESTMENT. The purchase
of and payment for the Capital Securities as described in this Agreement and
pursuant to the Subscription Agreement shall (a) not be prohibited by any
applicable law or governmental regulation, (b) not subject the Purchaser or the
Placement Agents to any penalty or, in the reasonable judgment of the Purchaser
and the Placement Agents, other onerous conditions under or pursuant to any
applicable law or governmental regulation, and (c) be permitted by the laws and
regulations of the jurisdictions to which the Purchaser and the Placement Agents
are subject.

     3.5. CONSENTS AND PERMITS. The Company and the Trust shall have received
all consents, permits and other authorizations, and made all such filings and
declarations, as may be required from any person or entity pursuant to any law,
statute, regulation or rule (federal, state, local and foreign), or pursuant to
any agreement, order or decree to which the Company or the Trust is a party or
to which either is subject, in connection with the transactions contemplated by
this Agreement.

     3.6. SALE OF PURCHASER SECURITIES. The Purchaser shall have sold securities
issued by the Purchaser in an amount such that the net proceeds of such sale
shall be (i) available on the Closing Date and (ii) in an amount sufficient to
purchase the Capital Securities and all other capital or similar securities
contemplated in agreements similar to this Agreement and the Subscription
Agreement.

     3.7. INFORMATION. Prior to or on the Closing Date, the Offerors shall have
furnished to the Placement Agents such further information, certificates,
opinions and documents addressed to the Purchaser and the Placement Agents,
which the Placement Agents may reasonably request, including, without
limitation, a complete set of the Operative Documents or any other documents or
certificates required by this Section 3; and all proceedings taken by the
Offerors in connection with the issuance, offer and sale of the Capital
Securities as herein contemplated shall be reasonably satisfactory in form and
substance to the Placement Agents.

     If any condition specified in this Section 3 shall not have been fulfilled
when and as required in this Agreement, or if any of the opinions or
certificates mentioned above or elsewhere in this Agreement shall not be
reasonably satisfactory in form and substance to the Placement Agents, this

          (A) Neither the Company nor the Trust, nor any of their "Affiliates"
(as defined in Rule 501(b) of Regulation D under the Securities Act ("Regulation
D")), nor any person acting on any of their behalf has, directly or indirectly,
made offers or sales of any security, or solicited offers to buy any security,
under circumstances that would require the registration under the Securities Act
of any of the Capital Securities, the Guarantee or the Debentures (collectively,
the "Securities") or any other securities to be issued, or which may be issued,
by the Purchaser.

          (B) Neither the Company nor the Trust, nor any of their Affiliates,

"Investment Company Act"), without regard to Section 3(c) of the Investment
Company Act.

          (E) Neither the Company nor the Trust has paid or agreed to pay to any
person or entity (other than the Placement Agents) any compensation for
soliciting another to purchase any of the Securities.

been duly created and is validly existing in good standing as a statutory trust
under the Delaware Statutory Trust Act (the "Statutory Trust Act") with the
power and authority to own property and to conduct the business it transacts and
proposes to transact and to enter into and perform its obligations under the
Operative Documents. The Trust is duly qualified to transact business as a
foreign entity and is in good standing in each jurisdiction in which such
qualification is necessary, except where the failure to so qualify or be in good
standing would not have a material adverse effect on the Trust. The Trust is not
a party to or


                                        5
<PAGE>
otherwise bound by any agreement other than the Operative Documents. The Trust
is and will, under current law, be classified for federal income tax purposes as
a grantor trust and not as an association taxable as a corporation.

     5.3. TRUST AGREEMENT. The Trust Agreement has been duly authorized by the
Company and, on the Closing Date, will have been duly executed and delivered by
the Company and the Administrators of the Trust, and, assuming due
authorization, execution and delivery by the Delaware Trustee and the

such Administrators, enforceable against them in accordance with its terms,
subject to (a) applicable bankruptcy, insolvency, moratorium, receivership,
reorganization, liquidation and other laws relating to or affecting creditors'
rights generally, and (b) general principles of equity (regardless of whether
considered and applied in a proceeding in equity or at law) ("Bankruptcy and
Equity"). Each of the Administrators of the Trust is an employee or a director
of the Company or of a financial institution subsidiary of the Company and has
been duly authorized by the Company to execute and deliver the Trust Agreement.

     5.4. GUARANTEE AGREEMENT AND THE INDENTURE. Each of the Guarantee and the
Indenture has been duly authorized by the Company and, on the Closing Date will
have been duly executed and delivered by the Company, and, assuming due
authorization, execution and delivery by the Guarantee Trustee, in the case of
the Guarantee, and by the Indenture Trustee, in the case of the Indenture, will
be a valid and binding obligation of the Company enforceable against it in
accordance with its terms, subject to Bankruptcy and Equity.

     5.5. CAPITAL SECURITIES AND COMMON SECURITIES. The Capital Securities and
the Common Securities have been duly authorized by the Trust Agreement and, when
issued and delivered against payment therefor on the Closing Date to the
Purchaser, in the case of the Capital Securities, and to the Company, in the
case of the Common Securities, will be validly issued and represent undivided
beneficial interests in the assets of the Trust. None of the Capital Securities
or the Common Securities is subject to preemptive or other similar rights. On
the Closing Date, all of the issued and outstanding Common Securities will be
directly owned by the Company free and clear of any pledge, security interest,
claim, lien or other encumbrance.

     5.6. DEBENTURES. The Debentures have been duly authorized by the Company
and, at the Closing Date, will have been duly executed and delivered to the
Indenture Trustee for authentication in accordance with the Indenture, and, when
authenticated in the manner provided for in the Indenture and delivered against
payment therefor by the Trust, will constitute valid and binding obligations of
the Company entitled to the benefits of the Indenture enforceable against the
Company in accordance with their terms, subject to Bankruptcy and Equity.

     5.7. POWER AND AUTHORITY. This Agreement has been duly authorized, executed
and delivered by the Company and the Trust and constitutes the valid and binding
obligation of the Company and the Trust, enforceable against the Company and the
Trust in accordance with its terms, subject to Bankruptcy and Equity.

     5.8. NO DEFAULTS. The Trust is not in violation of the Trust Agreement or,
to the knowledge of the Administrators, any provision of the Statutory Trust
Act. The execution, delivery and performance by the Company or the Trust of this
Agreement or the Operative Documents to which it is a party, and the
consummation of the transactions contemplated herein or therein and the use of
the proceeds therefrom, will not conflict with or constitute a breach of, or a
default under, or result in the creation or imposition of any lien, charge or
other encumbrance upon any property or assets of the Trust, the Company or any
of the Company's Subsidiaries (as defined in Section 5.11 hereof) pursuant to
any contract, indenture, mortgage, loan agreement, note, lease or other
instrument to which the Trust, the Company or any of its Subsidiaries is a party
or by which it or any of them may be bound, or to which any of the property or


                                        6
<PAGE>
assets of any of them is subject, except for a conflict, breach, default, lien,
charge or encumbrance which could not, singly or in the aggregate, reasonably be
expected to have a Material Adverse Effect nor will such action result in any
violation of the Trust Agreement or the Statutory Trust Act or require the
consent, approval, authorization or order of any court or governmental agency or
body. As used herein, the term "Material Adverse Effect" means any one or more
effects that individually or in the aggregate are material and adverse to the
Offerors' ability to consummate the transactions contemplated herein or in the
Operative Documents or any one or more effects that individually or in the
aggregate are material and adverse to the condition (financial or otherwise),
earnings, affairs, business, prospects or results of operations of the Company
and its Subsidiaries taken as whole, whether or not occurring in the ordinary
course of business.

     5.9. ORGANIZATION, STANDING AND QUALIFICATION OF THE COMPANY. The Company
has been duly incorporated and is validly existing as a corporation in good
standing under the laws of Missouri, with all requisite corporate power and
authority to own its properties and conduct the business it transacts and
proposes to transact, and is duly qualified to transact business and is in good
standing as a foreign corporation in each jurisdiction where the nature of its
activities requires such qualification, except where the failure of the Company
to be so qualified would not, singly or in the aggregate, have a Material
Adverse Effect.

     5.10. SUBSIDIARIES OF THE COMPANY. Each of the Company's significant
subsidiaries (as defined in Section 1-02(w) of Regulation S-X to the Securities
Act (the "Significant Subsidiaries")) is listed in Exhibit C attached hereto and
incorporated herein by this reference. Each Significant Subsidiary has been duly
organized and is validly existing and in good standing under the laws of the
jurisdiction in which it is chartered or organized, with all requisite power and
authority to own its properties and conduct the business it transacts and
proposes to transact, and is duly qualified to transact business and is in good
standing as a foreign entity in each jurisdiction where the nature of its
activities requires such qualification, except where the failure of any such
Significant Subsidiary to be so qualified would not, singly or in the aggregate,
have a Material Adverse Effect. All of the issued and outstanding shares of
capital stock of the Significant Subsidiaries (a) have been duly authorized and
are validly issued, (b) are fully paid and nonassessable, and (c) are wholly
owned, directly or indirectly, by the Company free and clear of any security
interest, mortgage, pledge, lien, encumbrance, restriction upon voting or
transfer, preemptive rights, claim, equity or other defect.

     5.11. PERMITS. The Company and each of its subsidiaries (as defined in
Section 1-02(x) of Regulation S-X to the Securities Act) (the "Subsidiaries")
have all requisite power and authority, and all necessary authorizations,

governmental officials, bodies and tribunals, to own or lease their respective
properties and to conduct their respective businesses as now being conducted,
except such authorizations, approvals, orders, licenses, certificates and
permits which, if not obtained and maintained, would not, singly or in the
aggregate, have a Material Adverse Effect, and neither the Company nor any of
its Subsidiaries has received any notice of proceedings relating to the
revocation or modification of any such authorizations, approvals, orders,
licenses, certificates or permits which, singly or in the aggregate, if the
failure to be so licensed or approved is the subject of an unfavorable decision,
ruling or finding, would, singly or in the aggregate, have a Material Adverse
Effect; and the Company and its Subsidiaries are in compliance with all
applicable laws, rules, regulations and orders and consents, the violation of
which would, singly or in the aggregate, have a Material Adverse Effect.

     5.12. CONFLICTS, AUTHORIZATIONS AND APPROVALS. Neither the Company nor any
of its Subsidiaries is in violation of its respective articles or certificate of
incorporation, charter or by-laws or similar organizational documents or in
default in the performance or observance of any obligation, agreement, covenant
or condition contained in any contract, indenture, mortgage, loan agreement,
note,

lease or other agreement or instrument to which either the Company or any of its
Subsidiaries is a party, or by which it or any of them may be bound or to which
any of the property or assets of the Company or any of its Subsidiaries is

policies, their ability or authority to pay dividends or make distributions to
their


                                        8
<PAGE>
shareholders or make payments of principal or interest on their debt
obligations, their management or their business (each, a "Regulatory
Agreement"), nor has the Company or any of its Subsidiaries been advised since
January 1, 2002, by any Regulatory Agency that it is considering issuing or
requesting any such Regulatory Agreement. There is no material unresolved
violation, criticism or exception by any Regulatory Agency with respect to any
report or statement relating to any examinations of the Company or any of its
Subsidiaries. As used herein, the term "Regulatory Agency" means any federal or
state agency charged with the supervision or regulation of depository
institutions, bank, financial or savings and loan holding companies, or engaged
in the insurance of depository institution deposits, or any court,
administrative agency or commission or other governmental agency, authority or
instrumentality having supervisory or regulatory authority with respect to the
Company or any of its Subsidiaries. Neither the Company nor any of the
Subsidiaries is currently unable to pay dividends or make distributions to its
shareholders with respect to any class of its equity securities, or prohibited
from paying principal or interest on its debt obligations, due to a restriction
or limitation, whether by statute, contract or otherwise, and, in the reasonable
judgment of the Company's management, neither the Company nor any of the
Subsidiaries will be unable in the foreseeable future to pay dividends or make
distributions with respect to any class of equity securities, or be prohibited
from paying principal or interest on its debt obligations, due to a restriction
or limitation, whether by statute, contract or otherwise.

     5.16. NO MATERIAL CHANGE. Since December 31, 2004, there has been no
material adverse change or development with respect to the condition (financial
or otherwise), earnings, affairs, business, prospects or results of operations
of the Company or its Subsidiaries on a consolidated basis, whether or not
arising in the ordinary course of business.

     5.17. NO UNDISCLOSED LIABILITIES. Neither the Company nor any of its
Subsidiaries has any material liability, whether known or unknown, whether
asserted or unasserted, whether absolute or contingent, whether accrued or
unaccrued, whether liquidated or unliquidated, and whether due or to become due,
including any liability for taxes (and there is no past or present fact,
situation, circumstance, condition or other basis for any present or future
action, suit, proceeding, hearing, charge, complaint, claim or demand against
the Company or its Subsidiaries giving rise to any such liability), except (i)
for liabilities set forth in the Financial Statements and (ii) normal
fluctuation in the amount of the liabilities referred to in clause (i) above
occurring in the ordinary course of business of the Company and all of its
Subsidiaries since the date of the most recent balance sheet included in the
Financial Statements.

     5.18. LITIGATION. No charge, investigation, action, suit or proceeding is
pending or, to the knowledge of the Offerors, threatened against or affecting
the Company or its Subsidiaries or any of their respective properties before or
by any courts or any regulatory, administrative or governmental official,
commission, board, agency or other authority or body, or any arbitrator, wherein
an unfavorable decision, ruling or finding could have, singly or in the
aggregate, a Material Adverse Effect.

     5.19. DEFERRAL OF INTEREST PAYMENTS ON DEBENTURES. The Company has no
present intention to exercise its option to defer payments of interest on the
Debentures as provided in the Indenture. The Company believes that the
likelihood that it would exercise its right to defer payments of interest on the
Debentures as provided in the Indenture at any time during which the Debentures
are outstanding is remote because of the restrictions that would be imposed on
the Company's ability to declare or pay dividends or distributions on, or to
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Company's capital stock and on the Company's ability to make any payments of
principal, interest or premium on, or repay, repurchase or redeem, any of its
debt securities that rank pari passu in all respects with, or junior in interest
to, the Debentures.

SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE PLACEMENT AGENTS. Each
Placement Agent represents and warrants to the Offerors as to itself (but not as
to the other Placement Agent) as follows:


                                        9
<PAGE>
     6.1. ORGANIZATION, STANDING AND QUALIFICATION.

          (A) FTN Financial Capital Markets is a division of First Tennessee
Bank National Association, a national banking association duly organized,
validly existing and in good standing under the laws of the United States, with
full power and authority to own, lease and operate its properties and conduct
its business as currently being conducted. FTN Financial Capital Markets is duly
qualified to transact business as a foreign corporation and is in good standing
in each other jurisdiction in which it owns or leases property or conducts its
business so as to require such qualification and in which the failure to so
qualify would, individually or in the aggregate, have a material adverse effect
on the condition (financial or otherwise), earnings, business, prospects or
results of operations of FTN Financial Capital Markets.

          (B) Keefe, Bruyette & Woods, Inc. is a corporation duly organized,
validly existing and in good standing under the laws of the State of New York,
with full power and authority to own, lease and operate its properties and
conduct its business as currently being conducted. Keefe, Bruyette & Woods, Inc.
is duly qualified to transact business as a foreign corporation and is in good
standing in each other jurisdiction in which it owns or leases property or
conducts its business so as to require such qualification and in which the
failure to so qualify would, individually or in the aggregate, have a material
adverse effect on the condition (financial or otherwise), earnings, business,
prospects or results of operations of Keefe, Bruyette & Woods, Inc.

     6.2. POWER AND AUTHORITY. The Placement Agent has all requisite power and
authority to enter into this Agreement, and this Agreement has been duly and
validly authorized, executed and delivered by the Placement Agent and
constitutes the legal, valid and binding agreement of the Placement Agent,
enforceable against the Placement Agent in accordance with its terms, subject to
Bankruptcy and Equity and except as any indemnification or contribution
provisions thereof may be limited under applicable securities laws.

     6.3. GENERAL SOLICITATION. In the case of the offer and sale of the Capital
Securities, no form of general solicitation or general advertising was used by
the Placement Agent or its representatives including, but not limited to,
advertisements, articles, notices or other communications published in any
newspaper, magazine or similar medium or broadcast over television or radio or
any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising. Neither the Placement Agent nor its
representatives have engaged or will engage in any "directed selling efforts"
within the meaning of Regulation S with respect to the Capital Securities.

     6.4. PURCHASER. The Placement Agent has made such reasonable inquiry as is
necessary to determine that the Purchaser is acquiring the Capital Securities
for its own account, that the Purchaser does not intend to distribute the
Capital Securities in contravention of the Securities Act or any other
applicable securities laws, and that the Purchaser is not a "U.S. person" as
that term is defined under Rule 902 of the Securities Act.

     6.5. QUALIFIED PURCHASERS. The Placement Agent has not offered or sold and
will not arrange for the offer or sale of the Capital Securities except (i) in
an offshore transaction complying with Rule 903 of Regulation S, or (ii) to
those the Placement Agent reasonably believes are "accredited investors" (as
defined in Rule 501 of Regulation D), or (iii) in any other manner that does not
require registration of the Capital Securities under the Securities Act. In
connection with each such sale, the Placement Agent has taken or will take
reasonable steps to ensure that the Purchaser is aware that (a) such sale is
being made in reliance on an exemption under the Securities Act and (b) future
transfers of the Capital Securities will not be made except in compliance with
applicable securities laws.


                                       10
<PAGE>
     6.6. OFFERING CIRCULARS. Neither the Placement Agent nor its
representatives will include any non-public information about the Company, the
Trust or any of their Affiliates in any registration statement, prospectus,
offering circular or private placement memorandum used in connection with any
purchase of Capital Securities without the prior written consent of the Trust
and the Company.

SECTION 7. COVENANTS OF THE OFFERORS. The Offerors covenant and agree with the
Placement Agents and the Purchaser as follows:

     7.1. COMPLIANCE WITH REPRESENTATIONS AND WARRANTIES. During the period from
the date of this Agreement to the Closing Date, the Offerors shall use their
best efforts and take all action necessary or appropriate to cause their
representations and warranties contained in Section 5 hereof to be true as of
the Closing Date, after giving effect to the transactions contemplated by this
Agreement, as if made on and as of the Closing Date.

     7.2. SALE AND REGISTRATION OF SECURITIES. The Offerors and their Affiliates
shall not nor shall any of them permit any person acting on their behalf (other
than the Placement Agents), to directly or indirectly (i) sell, offer for sale
or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in the Securities Act) that would or could be integrated with the sale
of the Capital Securities in a manner that would require the registration under
the Securities Act of the Securities or (ii) make offers or sales of any such
Security, or solicit offers to buy any such Security, under circumstances that
would require the registration of any of such Securities under the Securities
Act.

     7.3. USE OF PROCEEDS. The Trust shall use the proceeds from the sale of the
Capital Securities and the Common Securities to purchase the Debentures from the
Company.

     7.4. INVESTMENT COMPANY. The Offerors shall not engage, or permit any
Subsidiary to engage, in any activity which would cause it or any Subsidiary to
be an "investment company" under the provisions of the Investment Company Act.

     7.5. REIMBURSEMENT OF EXPENSES. If the sale of the Capital Securities
provided for herein is not consummated (i) because any condition set forth in
Section 3 hereof is not satisfied, or (ii) because of any refusal, inability or
failure on the part of the Company or the Trust to perform any agreement herein
or comply with any provision hereof other than by reason of a breach by the
Placement Agents, the Company shall reimburse the Placement Agents upon demand
for all of their pro rata share of out-of-pocket expenses (including reasonable
fees and disbursements of counsel) in an amount not to exceed $50,000.00 that
shall have been incurred by them in connection with the proposed purchase and
sale of the Capital Securities. Notwithstanding the foregoing, the Company shall
have no obligation to reimburse the Placement Agents for their out-of-pocket
expenses if the sale of the Capital Securities fails to occur because the
condition set forth in Section 3.6 is not satisfied or because either of the
Placement Agents fails to fulfill a condition set forth in Section 4 or the
Purchaser fails to purchase the Capital Securities.

     7.6. DIRECTED SELLING EFFORTS, SOLICITATION AND ADVERTISING. In connection
with any offer or sale of any of the Securities, the Offerors shall not, nor
shall either of them permit any of their Affiliates or any person acting on
their behalf, other than the Placement Agents, to, (i) engage in any "directed
selling efforts" within the meaning of Regulation S, or (ii) engage in any form
of general solicitation or general advertising (as defined in Regulation D).

     7.7. COMPLIANCE WITH RULE 144A(D)(4) UNDER THE SECURITIES ACT. So long as
any of the Securities are outstanding and are "restricted securities" within the
meaning of Rule 144(a)(3) under the Securities Act, the Offerors will, during
any period in which they are not subject to and in compliance with Section 13 or
15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
or


                                       11
<PAGE>
the Offerors are not exempt from such reporting requirements pursuant to and in
compliance with Rule 12g3-2(b) under the Exchange Act, provide to each holder of
such restricted securities and to each prospective purchaser (as designated by
such holder) of such restricted securities, upon the request of such holder or
prospective purchaser in connection with any proposed transfer, any information
required to be provided by Rule 144A(d)(4) under the Securities Act, if
applicable. This covenant is intended to be for the benefit of the holders, and
the prospective purchasers designated by such holders, from time to time of such
restricted securities. The information provided by the Offerors pursuant to this
Section 7.7 will not, at the date thereof, contain any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

     7.8. QUARTERLY REPORTS. Within 50 days of the end of each calendar year
quarter and within 100 days of the end of each calendar year during which the
Debentures are issued and outstanding, the Offerors shall submit to The Bank of
New York a completed quarterly report in the form attached hereto as Exhibit D.
The Offerors acknowledge and agree that The Bank of New York and its successors
and assigns are third party beneficiaries of this Section 7.8.

SECTION 8. COVENANTS OF THE PLACEMENT AGENTS. The Placement Agents covenant and
agree with the Offerors that, during the period from the date of this Agreement
to the Closing Date, the Placement Agents shall use their best efforts and take
all action necessary or appropriate to cause their representations and
warranties contained in Section 6 to be true as of Closing Date, after giving
effect to the transactions contemplated by this Agreement, as if made on and as
of the Closing Date. The Placement Agents further covenant and agree not to
engage in hedging transactions with respect to the Capital Securities unless
such transactions are conducted in compliance with the Securities Act.

SECTION 9. INDEMNIFICATION.

     9.1. INDEMNIFICATION OBLIGATION. The Offerors shall jointly and severally
indemnify and hold harmless the Placement Agents and the Purchaser and each of
their respective agents, employees, officers and directors and each person that
controls either of the Placement Agents or the Purchaser within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, and agents,
employees, officers and directors or any such controlling person of either of
the Placement Agents or the Purchaser (each such person or entity, an
"Indemnified Party") from and against any and all losses, claims, damages,
judgments, liabilities or expenses, joint or several, to which such Indemnified
Party may become subject under the Securities Act, the Exchange Act or other
federal or state statutory law or regulation, or at common law or otherwise
(including in settlement of any litigation, if such settlement is effected with
the written consent of the Offerors), insofar as such losses, claims, damages,
judgments, liabilities or expenses (or actions in respect thereof) arise out of,
or are based upon, or relate to, in whole or in part, (a) any untrue statement
or alleged untrue statement of a material fact contained in any information
(whether written or oral) or documents executed in favor of, furnished or made
available to the Placement Agents or the Purchaser by the Offerors, or (b) any
omission or alleged omission to state in any information (whether written or
oral) or documents executed in favor of, furnished or made available to the
Placement Agents or the Purchaser by the Offerors a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
shall reimburse each Indemnified Party for any legal and other expenses as such
expenses are reasonably incurred by such Indemnified Party in connection with
investigating, defending, settling, compromising or paying any such loss, claim,
damage, judgments, liability, expense or action described in this Section 9.1.
In addition to their other obligations under this Section 9, the Offerors hereby
agree that, as an interim measure during the pendency of any claim, action,
investigation, inquiry or other proceeding arising out of, or based upon, or
related to the matters described above in this Section 9.1, they shall reimburse
each Indemnified Party on a quarterly basis for all reasonable legal or other
expenses incurred in connection with investigating or defending any


                                       12
<PAGE>
such claim, action, investigation, inquiry or other proceeding, notwithstanding
the absence of a judicial determination as to the propriety and enforceability
of the possibility that such payments might later be held to have been improper
by a court of competent jurisdiction. To the extent that any such interim
reimbursement payment is so held to have been improper, each Indemnified Party
shall promptly return such amounts to the Offerors together with interest,
determined on the basis of the prime rate (or other commercial lending rate for
borrowers of the highest credit standing) announced from time to time by First
Tennessee Bank National Association (the "Prime Rate"). Any such interim
reimbursement payments which are not made to an Indemnified Party within 30 days
of a request for reimbursement shall bear interest at the Prime Rate from the
date of such request.

     9.2. CONDUCT OF INDEMNIFICATION PROCEEDINGS. Promptly after receipt by an
Indemnified Party under this Section 9 of notice of the commencement of any
action, such Indemnified Party shall, if a claim in respect thereof is to be
made against the Offerors under this Section 9, notify the Offerors in writing
of the commencement thereof; but, subject to Section 9.4, the omission to so
notify the Offerors shall not relieve them from any liability pursuant to
Section 9.1 which the Offerors may have to any Indemnified Party unless and to
the extent that the Offerors did not otherwise learn of such action and such
failure by the Indemnified Party results in the forfeiture by the Offerors of
substantial rights and defenses. In case any such action is brought against any
Indemnified Party and such Indemnified Party seeks or intends to seek indemnity
from the Offerors, the Offerors shall be entitled to participate in, and, to the
extent that they may wish, to assume the defense thereof with counsel reasonably
satisfactory to such Indemnified Party; provided, however, if the defendants in
any such action include both the Indemnified Party and the Offerors and the
Indemnified Party shall have reasonably concluded that there may be a conflict
between the positions of the Offerors and the Indemnified Party in conducting
the defense of any such action or that there may be legal defenses available to
it and/or other Indemnified Parties which are different from or additional to
those available to the Offerors, the Indemnified Party shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such Indemnified Party.
Upon receipt of notice from the Offerors to such Indemnified Party of their
election to so assume the defense of such action and approval by the Indemnified
Party of counsel, the Offerors shall not be liable to such Indemnified Party
under this Section 9 for any legal or other expenses subsequently incurred by
such Indemnified Party in connection with the defense thereof unless (i) the
Indemnified Party shall have employed such counsel in connection with the
assumption of legal defenses in accordance with the proviso in the preceding
sentence (it being understood, however, that the Offerors shall not be liable
for the expenses of more than one separate counsel representing the Indemnified
Parties who are parties to such action), or (ii) the Offerors shall not have
employed counsel reasonably satisfactory to the Indemnified Party to represent
the Indemnified Party within a reasonable time after notice of commencement of
the action, in each of which cases the fees and expenses of counsel of such
Indemnified Party shall be at the expense of the Offerors.

     9.3. CONTRIBUTION. If the indemnification provided for in this Section 9 is
required by its terms, but is for any reason held to be unavailable to or
otherwise insufficient to hold harmless an Indemnified Party under Section 9.1
in respect of any losses, claims, damages, liabilities or expenses referred to
herein or therein, then the Offerors shall contribute to the amount paid or
payable by such Indemnified Party as a result of any losses, claims, damages,
judgments, liabilities or expenses referred to herein (i) in such proportion as
is appropriate to reflect the relative benefits received by the Offerors, on the
one hand, and the Indemnified Party, on the other hand, from the offering of
such Capital Securities, or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Offerors, on the one hand, and the Placement Agents,
on the other hand, in connection with the statements or omissions or
inaccuracies in the representations and warranties herein or other breaches
which resulted in such losses, claims, damages, judgments, liabilities or
expenses, as well as any other relevant equitable considerations. The respective
relative benefits received by the Offerors, on the one


                                       13
<PAGE>
hand, and the Placement Agents, on the other hand, shall be deemed to be in the
same proportion, in the case of the Offerors, as the total price paid to the
Offerors for the Capital Securities sold by the Offerors to the Purchaser (net
of the compensation paid to the Placement Agents hereunder, but before deducting
expenses), and in the case of the Placement Agents, as the compensation received
by them, bears to the total of such amounts paid to the Offerors and received by
the Placement Agents as compensation. The relative fault of the Offerors and the
Placement Agents shall be determined by reference to, among other things,
whether the untrue statement or alleged untrue statement of a material fact or
the omission or alleged omission of a material fact or the inaccurate or the
alleged inaccurate representation and/or warranty relates to information
supplied by the Offerors or the Placement Agents and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The provisions set forth in Section 9.2 with respect
to notice of commencement of any action shall apply if a claim for contribution
is made under this Section 9.3; provided, however, that no additional notice
shall be required with respect to any action for which notice has been given
under Section 9.2 for purposes of indemnification. The Offerors and the
Placement Agents agree that it would not be just and equitable if contribution
pursuant to this Section 9.3 were determined by pro rata allocation or by any
other method of allocation that does not take account of the equitable
considerations referred to in this Section 9.3. The amount paid or payable by an
Indemnified Party as a result of the losses, claims, damages, judgments,
liabilities or expenses referred to in this Section 9.3 shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim. In no event shall the liability of the
Placement Agents hereunder be greater in amount than the dollar amount of the
compensation (net of payment of all expenses) received by the Placement Agents
upon the sale of the Capital Securities giving rise to such obligation. No
person found guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not found guilty of such fraudulent misrepresentation.

     9.4. ADDITIONAL REMEDIES. The indemnity and contribution agreements
contained in this Section 9 are in addition to any liability that the Offerors
may otherwise have to any Indemnified Party.

     9.5. ADDITIONAL INDEMNIFICATION. The Company shall indemnify and hold
harmless the Trust against all loss, liability, claim, damage and expense
whatsoever, as due from the Trust under Sections 9.1 through 9.4 hereof.

SECTION 10. RIGHTS AND RESPONSIBILITIES OF PLACEMENT AGENTS.

     10.1. RELIANCE. In performing their duties under this Agreement, the
Placement Agents shall be entitled to rely upon any notice, signature or writing
which they shall in good faith believe to be genuine and to be signed or
presented by a proper party or parties. The Placement Agents may rely upon any
opinions or certificates or other documents delivered by the Offerors or their
counsel or designees to either the Placement Agents or the Purchaser.

     10.2. RIGHTS OF PLACEMENT AGENTS. In connection with the performance of
their duties under this Agreement, the Placement Agents shall not be liable for
any error of judgment or any action taken or omitted to be taken unless the
Placement Agents were grossly negligent or engaged in willful misconduct in
connection with such performance or non-performance. No provision of this
Agreement shall require the Placement Agents to expend or risk their own funds
or otherwise incur any financial liability on behalf of the Purchaser in
connection with the performance of any of their duties hereunder. The Placement
Agents shall be under no obligation to exercise any of the rights or powers
vested in them by this Agreement.


                                       14
<PAGE>
SECTION 11. MISCELLANEOUS.

     11.1. DISCLOSURE SCHEDULE. The term "Disclosure Schedule," as used herein,
means the schedule, if any, attached to this Agreement that sets forth items the
disclosure of which is necessary or appropriate as an exception to one or more
representations or warranties contained in Section 5 hereof; provided, that any
item set forth in the Disclosure Schedule as an exception to a representation or
warranty shall be deemed an admission by the Offerors that such item represents
an exception, fact, event or circumstance that is reasonably likely to result in
a Material Adverse Effect. The Disclosure Schedule shall be arranged in
paragraphs corresponding to the section numbers contained in Section 5. Nothing
in the Disclosure Schedule shall be deemed adequate to disclose an exception to
a representation or warranty made herein unless the Disclosure Schedule
identifies the exception with reasonable particularity and describes the
relevant facts in reasonable detail. Without limiting the generality of the
immediately preceding sentence, the mere listing (or inclusion of a copy) of a
document or other item in the Disclosure Schedule shall not be deemed adequate
to disclose an exception to a representation or warranty made herein unless the
representation or warranty has to do with the existence of the document or other
item itself. Information provided by the Company in response to any due
diligence questionnaire shall not be deemed part of the Disclosure Schedule and
shall not be deemed to be an exception to one or more representations or
warranties contained in Section 5 hereof unless such information is specifically
included on the Disclosure Schedule in accordance with the provisions of this
Section 11.1.

     11.2. LEGAL EXPENSES. At Closing, the Placement Agents shall provide a
credit for the Offerors' transaction-related legal expenses in the amount of
$10,000.00.

     11.3. NON-DISCLOSURE. Except as required by applicable law, including
without limitation securities laws and regulations promulgated thereunder, (i)
the Offerors shall not, and will cause their advisors and representatives not
to, issue any press release or other public statement regarding the transactions
contemplated by this Agreement or the Operative Documents prior to or on the
Closing Date and (ii) following the Closing Date, the Offerors shall not include
in any press release, other public statement or other public communication
regarding the transactions contemplated by this Agreement or the Operative
Documents, any reference to the Placement Agents, WTC, the Purchaser, the term
"PreTS" or any derivations thereof. Notwithstanding anything to the contrary,
the Offerors may (1) consult any tax advisor regarding U.S. federal income tax
treatment or tax structure of the transaction contemplated under this Agreement
and the Operative Documents and (2) disclose to any and all persons, without
limitation of any kind, the U.S. Federal income tax structure (in each case,
within the meaning of Treasury Regulation Section 1.6011-4) of the transaction
contemplated under this Agreement and the Operative Documents and all materials
of any kind (including opinions or other tax analyses) that are provided to you
relating to such tax treatment and tax structure. For this purpose, "tax
structure" is limited to any facts relevant to the U.S. federal income tax
treatment of the transaction and does not include information relating to
identity of the parties.

     11.4. NOTICES. Prior to the Closing, and thereafter with respect to matters
pertaining to this Agreement only, all notices and other communications provided
for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telex, telecopier or overnight air courier guaranteeing next
day delivery:

                       EXCHANGE NATIONAL BANCSHARES, INC.

                             SUBSCRIPTION AGREEMENT

                                 MARCH 17, 2005

     THIS SUBSCRIPTION AGREEMENT (this "Agreement") made among Exchange National
Statutory Trust II (the "Trust"), a statutory trust created under the Delaware
Statutory Trust Act (Chapter 38 of Title 12 of the Delaware Code, 12 Del. C.
Sections 3801, et seq.), Exchange National Bancshares, Inc., a Missouri
corporation, with its principal offices located at 132 East High Street,
Jefferson City, Missouri 65102 (the "Company" and, collectively with the Trust,
the "Offerors"), and Preferred Term Securities XVII, Ltd. (the "Purchaser").

                                    RECITALS:

     A. The Trust desires to issue 23,000 of its Fixed/Floating Rate Capital
Securities (the "Capital Securities"), liquidation amount $1,000.00 per Capital
Security, representing an undivided beneficial interest in the assets of the
Trust (the "Offering"), to be issued pursuant to an Amended and Restated
Declaration of Trust (the "Declaration") by and among the Company, Wilmington
Trust Company ("WTC"), the administrators named therein, and the holders (as
defined therein), which Capital Securities are to be guaranteed by the Company
with respect to distributions and payments upon liquidation, redemption and
otherwise pursuant to the terms of a Guarantee Agreement between the Company and
WTC, as trustee (the "Guarantee"); and

     B. The proceeds from the sale of the Capital Securities will be combined
with the proceeds from the sale by the Trust to the Company of its common
securities, and will be used by the Trust to purchase an equivalent amount of
Fixed/Floating Rate Junior Subordinated Deferrable Interest Debentures of the
Company (the "Debentures") to be issued by the Company pursuant to an indenture
to be executed by the Company and WTC, as trustee (the "Indenture"); and

     C. In consideration of the premises and the mutual representations and
covenants hereinafter set forth, the parties hereto agree as follows:

                                    ARTICLE I

                     PURCHASE AND SALE OF CAPITAL SECURITIES

     1.1. Upon the execution of this Agreement, the Purchaser hereby agrees to
purchase from the Trust 23,000 Capital Securities at a price equal to $1,000.00
per Capital Security (the "Purchase Price") and the Trust agrees to sell such
Capital Securities to the Purchaser for said Purchase Price. The rights and
preferences of the Capital Securities are set forth in the Declaration. The
Purchase Price is payable in immediately available funds on March 17, 2005, or
such other business day as may be designated by the Purchaser, but in no event
later than March 31, 2005 (the "Closing Date"). The Offerors shall provide the
Purchaser wire transfer instructions no later than 1 day following the date
hereof.

     1.2. The certificate for the Capital Securities shall be delivered by the
Trust on the Closing Date to the Purchaser or its designee.

     1.3. The Placement Agreement, dated March 9, 2005 (the "Placement
Agreement"), among the Offerors and the Placement Agents identified therein
includes certain representations and warranties, covenants and conditions to
closing and certain other matters governing the Offering. The Placement
Agreement is hereby incorporated by reference into this Agreement and the
Purchaser shall be entitled to each of the benefits of the Placement Agents and
the Purchaser under the Placement Agreement and shall be entitled to enforce the
obligations of the Offerors under such Placement Agreement as fully as if the
Purchaser were a party to such Placement Agreement.

                                   ARTICLE II

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

     2.1. The Purchaser understands and acknowledges that neither the Capital
Securities, the Debentures nor the Guarantee have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), or any other
applicable securities law, are being offered for sale by the Trust in
transactions not requiring registration under the Securities Act, and may not be
offered, sold, pledged or otherwise transferred by the Purchaser except in
compliance with the registration requirements of the Securities Act or any other
applicable securities laws, pursuant to an exemption therefrom or in a
transaction not subject thereto.

     2.2. The Purchaser represents, warrants and certifies that (i) it is not a
"U.S. person" as such term is defined in Rule 902 under the Securities Act, (ii)
it is not acquiring the Capital Securities for the account or benefit of any
such U.S. person, (iii) the offer and sale of Capital Securities to the
Purchaser constitutes an "offshore transaction" under Regulation S of the
Securities Act, and (iv) it will not engage in hedging transactions with regard
to the Capital Securities unless such transactions are conducted in compliance
with the Securities Act and the Purchaser agrees to the legends and transfer
restrictions set forth on the Capital Securities certificate.

     2.3. The Purchaser represents and warrants that it is purchasing the
Capital Securities for its own account, for investment, and not with a view to,
or for offer or sale in connection with, any distribution thereof in violation
of the Securities Act or other applicable securities laws, subject to any
requirement of law that the disposition of its property be at all times within
its control and subject to its ability to resell such Capital Securities
pursuant to an effective registration statement under the Securities Act or
under Rule 144A or any other exemption from registration available under the
Securities Act or any other applicable Securities law.

     2.4. The Purchaser represents and warrants that it has full power and
authority to execute and deliver this Agreement, to make the representations and
warranties specified herein, and to consummate the transactions contemplated
herein and it has full right and power to subscribe for Capital Securities and
perform its obligations pursuant to this Agreement.

     2.5. The Purchaser, a Cayman Islands Company whose business includes
issuance of certain notes and acquiring the Capital Securities and other similar
securities, represents and warrants that it has such knowledge and experience in
financial and business matters that it is capable of evaluating the merits and
risks of purchasing the Capital Securities, has had the opportunity to ask
questions of, and receive answers and request additional information from, the
Offerors and is aware that it may be required to bear the economic risk of an
investment in the Capital Securities.

     2.6. The Purchaser represents and warrants that no filing with, or
authorization, approval, consent, license, order, registration, qualification or
decree of, any governmental body, agency or court having jurisdiction over the
Purchaser, other than those that have been made or obtained, is necessary or


                                      A-2
<PAGE>
required for the performance by the Purchaser of its obligations under this
Agreement or to consummate the transactions contemplated herein.

     2.7. The Purchaser represents and warrants that this Agreement has been
duly authorized, executed and delivered by the Purchaser.

     2.8. The Purchaser represents and warrants that (i) the Purchaser is not in
violation or default of any term of its Memorandum of Association or Articles of
Association, of any provision of any mortgage, indenture, contract, agreement,
instrument or contract to which it is a party or by which it is bound or of any
judgment, decree, order, writ or, to its knowledge, any statute, rule or
regulation applicable to the Purchaser which would prevent the Purchaser from
performing any material obligation set forth in this Agreement; and (ii) the
execution, delivery and performance of and compliance with this Agreement, and
the consummation of the transactions contemplated herein, will not, with or
without the passage of time or giving of notice, result in any such material
violation, or be in conflict with or constitute a default under any such term,
or the suspension, revocation, impairment, forfeiture or non-renewal of any
permit, license, authorization or approval applicable to the Purchaser, its
business or operations or any of its assets or properties which would prevent
the Purchaser from performing any material obligations set forth in this
Agreement.

     2.9. The Purchaser represents and warrants that the Purchaser is an
exempted company with limited liability duly incorporated, validly existing and
in good standing under the laws of the jurisdiction where it is organized, with
full power and authority to perform its obligations under this Agreement.

     2.10. The Purchaser understands and acknowledges that the Company will rely
upon the truth and accuracy of the foregoing acknowledgments, representations,
warranties and agreements and agrees that, if any of the acknowledgments,
representations, warranties or agreements deemed to have been made by it by its
purchase of the Capital Securities are no longer accurate, it shall promptly
notify the Company.

     2.11. The Purchaser understands that no public market exists for any of the
Capital Securities, and that it is unlikely that a public market will ever exist
for the Capital Securities.

                                   ARTICLE III

Ladies and Gentlemen:

     We have acted as counsel to Exchange National Bancshares, Inc. (the
"Company"), a Missouri corporation in connection with a certain Placement
Agreement, dated March 9, 2005, (the "Placement Agreement"), between the Company
and Exchange National Statutory Trust II (the "Trust"), on one hand, and FTN
Financial Capital Markets and Keefe, Bruyette & Woods, Inc. (the "Placement
Agents"), on the other hand. Pursuant to the Placement Agreement, and subject to
the terms and conditions stated therein, the Trust will issue and sell to
Preferred Term Securities XVII, Ltd. (the "Purchaser"), $23,000,000.00 aggregate
principal amount of Fixed/Floating Rate Capital Securities (liquidation amount
$1,000.00 per capital security) (the "Capital Securities").

     Capitalized terms used herein and not otherwise defined shall have the same
meanings ascribed to them in the Placement Agreement.

     The law covered by the opinions expressed herein is limited to the law of
the United States of America and of the State of Missouri.

     We have made such investigations of law as, in our judgment, were necessary
to render the following opinions. We have also reviewed (a) the Company's
Articles of Incorporation, as amended, and its By-Laws, as amended; and (b) such
corporate documents, records, information and certificates of the Company and
the Subsidiaries, certificates of public officials or government authorities and
other documents as we have deemed necessary or appropriate as a basis for the
opinions hereinafter expressed. As to certain facts material to our opinions, we
have relied, with your permission, upon statements, certificates or
representations, including those delivered or made in connection with the
above-referenced transaction, of officers and other representatives of the
Company and the Subsidiaries and the Trust.

     As used herein, the phrases "to the best of our knowledge" or "known to us"
or other similar phrases mean the actual knowledge of the attorneys who have had
active involvement in the transactions described above or who have prepared or
signed this opinion letter, or who otherwise have devoted substantial attention
to legal matters for the Company.


                                      B-1-1
<PAGE>
     Based upon and subject to the foregoing and the further qualifications set
forth below, we are of the opinion as of the date hereof that:

     1. The Company is validly existing and in good standing under the laws of
the State of Missouri and is duly registered as a bank holding company under the
Bank Holding Company Act of 1956, as amended. Each of the Significant
Subsidiaries is validly existing and in good standing under the laws of its
jurisdiction of organization. Each of the Company and the Significant
Subsidiaries has full corporate power and authority to own or lease its
properties and to conduct its business as such business is currently conducted
in all material respects. To the best of our knowledge, all outstanding shares
of capital stock of the Significant Subsidiaries have been duly authorized and
validly issued, and are fully paid and nonassessable except to the extent such
shares may be deemed assessable under 12 U.S.C. Section 1831o or 12 U.S.C.
Section 55, and are owned of record and beneficially, directly or indirectly, by
the Company.

     2. The issuance, sale and delivery of the Debentures in accordance with the
terms and conditions of the Placement Agreement and the Operative Documents have
been duly authorized by all necessary actions of the Company. The issuance, sale
and delivery of the Debentures by the Company and the issuance, sale and
delivery of the Capital Securities and the Common Securities by the Trust do not
give rise to any preemptive or other rights to subscribe for or to purchase any
shares of capital stock or equity securities of the Company or the Significant
Subsidiaries pursuant to the corporate Articles of Incorporation or Charter,
By-Laws or other governing documents of the Company or the Significant
Subsidiaries, or, to the best of our knowledge, any agreement or other
instrument to which either the Company or the Subsidiaries is a party or by
which the Company or the Significant Subsidiaries may be bound.

     3. The Company has all requisite corporate power to enter into and perform
its obligations under the Placement Agreement and the Subscription Agreement,
and the Placement Agreement and the Subscription Agreement have been duly and
validly authorized, executed and delivered by the Company and constitute the
legal, valid and binding obligations of the Company enforceable in accordance
with their terms, except as the enforcement thereof may be limited by general
principles of equity and by bankruptcy or other laws affecting creditors' rights
generally, and except as the indemnification and contribution provisions thereof
may be limited under applicable laws and certain remedies may not be available
in the case of a non-material breach.

     4. Each of the Indenture, the Trust Agreement and the Guarantee Agreement
has been duly authorized, executed and delivered by the Company, and is a valid
and legally binding obligation of the Company enforceable in accordance with its
terms, subject to the effect of bankruptcy, insolvency, reorganization,
receivership, moratorium and other laws affecting the rights and remedies of
creditors generally and of general principles of equity.

     5. The Debentures have been duly authorized, executed and delivered by the
Company, are entitled to the benefits of the Indenture and are legal, valid and
binding obligations of the Company enforceable against the Company in accordance
with their terms, subject to the effect of bankruptcy, insolvency,
reorganization, receivership, moratorium and other laws affecting the rights and
remedies of creditors generally and of general principles of equity.

     6. To the best of our knowledge, neither the Company, the Trust, nor any of
the Subsidiaries is in breach or violation of, or default under, with or without
notice or lapse of time or both, its Articles of Incorporation or Charter,
By-Laws or other governing documents (including without limitation, the Trust
Agreement). The execution, delivery and performance of the Placement Agreement
and the Operative Documents and the consummation of the transactions
contemplated by the Placement Agreement and the


                                      B-1-2
<PAGE>
Operative Documents do not and will not (i) result in the creation or imposition
of any material lien, claim, charge, encumbrance or restriction upon any
property or assets of the Company or the Subsidiaries, or (ii) conflict with,
constitute a material breach or violation of, or constitute a material default
under, with or without notice or lapse of time or both, any of the terms,
provisions or conditions of (A) the Articles of Incorporation or Charter,
By-Laws or other governing documents of the Company or the Subsidiaries, or (B)
to the best of our knowledge, any material contract, indenture, mortgage, deed
of trust, loan or credit agreement, note, lease, franchise, license or any other
agreement or instrument to which the Company or the Subsidiaries is a party or
by which any of them or any of their respective properties may be bound or (C)
any order, decree, judgment, franchise, license, permit, rule or regulation of
any court, arbitrator, government, or governmental agency or instrumentality,
domestic or foreign, known to us having jurisdiction over the Company or the
Subsidiaries or any of their respective properties which, in the case of each of
(i) or (ii) above, is material to the Company and the Subsidiaries on a
consolidated basis.

     7. Except for filings, registrations or qualifications that may be required
by applicable securities laws, no authorization, approval, consent or order of,
or filing, registration or qualification with, any person (including, without
limitation, any court, governmental body or authority) is required under the
laws of the State of Missouri in connection with the transactions contemplated
by the Placement Agreement and the Operative Documents in connection with the
offer and sale of the Capital Securities as contemplated by the Placement
Agreement and the Operative Documents.

     8. To the best of our knowledge (i) no action, suit or proceeding at law or
in equity is pending or threatened to which the Company, the Trust or the
Subsidiaries are or may be a party, and (ii) no action, suit or proceeding is
pending or threatened against or affecting the Company, the Trust or the
Subsidiaries or any of their properties, before or by any court or governmental
official, commission, board or other administrative agency, authority or body,
or any arbitrator, wherein an unfavorable decision, ruling or finding could
reasonably be expected to have a material adverse effect on the consummation of
the transactions contemplated by the Placement Agreement and the Operative
Documents or the issuance and sale of the Capital Securities as contemplated
therein or the condition (financial or otherwise), earnings, affairs, business,
or results of operations of the Company, the Trust and the Subsidiaries on a
consolidated basis.

     9. Assuming the truth and accuracy of the representations and warranties of
the Placement Agents in the Placement Agreement and the Purchaser in the
Subscription Agreement, it is not necessary in connection with the offering,
sale and delivery of the Capital Securities, the Debentures and the Guarantee
Agreement (or the Guarantee) to register the same under the Securities Act of
1933, as amended, under the circumstances contemplated in the Placement
Agreement and the Subscription Agreement.

     10. Neither the Company nor the Trust is or after giving effect to the
offering and sale of the Capital Securities and the consummation of the
transactions described in the Placement Agreement will be, an "investment
company" or an entity "controlled" by an "investment company," in each case
within the meaning of the Investment Company Act of 1940, as amended, without
regard to Section 3(c) of such Act.

     The opinion expressed in the first two sentences of numbered paragraph 1 of
this opinion is based solely upon certain certificates and confirmations issued
by the applicable governmental officer or authority with respect to each of the
Company and the Significant Subsidiaries.

     With respect to the foregoing opinions, since no member of this firm is
actively engaged in the practice of law in the States of Delaware or New York,
we do not express any opinions as to the laws of


                                      B-1-3
<PAGE>
such states and have (i) relied, with your approval, upon the opinion of
Richards, Layton & Finger, P.A. with respect to matters of Delaware law and (ii)
assumed, with your approval and without rendering any opinion to such effect,
that the laws of the State of New York, in all respects material to this
opinion, are substantively identical to the laws of the State of Missouri,
without regard to conflict of law provisions.

     The opinions expressed herein are rendered to you solely pursuant to
Section 3.1(a) of the Placement Agreement. As such, they may be relied upon by
you only and may not be used or relied upon by any other person for any purpose
whatsoever without our prior written consent.

                                        Very truly yours,

          Capitalized terms used herein and not otherwise defined are used as
defined in the Declaration of Trust, except that reference herein to any

is being delivered pursuant to Section 3.1 of the Placement Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (h) above. In particular, we
have not reviewed any document (other than the documents listed in paragraphs

the documents reviewed by us. We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein. We have conducted no independent factual investigation of our own
but rather have relied solely upon the foregoing documents, the statements and
information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or

operation, and termination of the Trust, and that the Declaration of Trust and
the Certificate of Trust are in full force and effect and have not been amended
further, (ii) that there are no proceedings pending or contemplated, for the
merger, consolidation, liquidation, dissolution or termination of the Trust,
(iii) except to the extent provided in paragraph 1 below, the due creation, due
formation or due organization, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, formation or organization, (iv) that each
party to the documents examined by us is qualified to do business in each
jurisdiction where such qualification is required generally or necessary in
order for such party to enforce its rights under the documents examined by us,
(v) the legal capacity of each natural person who is a party to the documents

parties to the documents examined by us has duly authorized, executed and
delivered such documents, (viii) the receipt by each Person to whom a Capital
Security is to be issued by the Trust (the "Capital Security Holders") of a
Capital Security Certificate for the Capital Security and the payment for the
Capital Securities acquired by it, in accordance with the Declaration of Trust
and the Subscription Agreement, (ix) that the Capital Securities are issued and
sold to the Holders of the Capital Securities in accordance with the Declaration
of Trust and the Subscription Agreement, (x) the receipt by the Person (the
"Common Securityholder") to whom the common securities of the Trust representing
common undivided beneficial interests in the assets of the Trust (the "Common
Securities" and, together with the Capital Securities, the "Trust Securities")
are to be issued by the Trust of a Common Security Certificate for the Common
Securities and the payment for the Common Securities acquired by it, in
accordance with the Declaration of Trust, (xi) that the Common Securities are
issued and sold to the Common Securityholder in accordance with the Declaration
of Trust, (xii) that each of the parties to the documents reviewed by us has
agreed to and received the stated consideration for the incurrence of its

                                      B-2-2

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

          We express no opinion as to (i) the effect of suretyship defenses, or
defenses in the nature thereof, with respect to the obligations of any
applicable guarantor, joint obligor, surety, accommodation party, or other
secondary obligor or any provisions of the Declaration of Trust with respect to
indemnification or contribution and (ii) the accuracy or completeness of any
exhibits or schedules to the Operative Documents. No opinion is given herein as
to the choice of law or internal substantive rules of law that any court or
other tribunal may apply to the transactions contemplated by the Operative
Documents.

          We express no opinion as to the enforceability of any particular
provision of the Declaration of Trust or the other Operative Documents relating
to remedies after default.

          We express no opinion as to the enforceability of any particular
provision of any of the Operative Documents relating to (i) waivers of rights to
object to jurisdiction or venue, or consents to jurisdiction or venue, (ii)
waivers of rights to (or methods of) service of process, or rights to trial by
jury, or other rights or benefits bestowed by operation of law, (iii) waivers of
any applicable defenses, setoffs, recoupments, or counterclaims, (iv) waivers or
variations of provisions which are not capable of waiver or variation under the
Uniform Commercial Code ("UCC") of the State, (v) the grant of powers of
attorney to any person or entity, or (vi) exculpation or exoneration clauses,
indemnity clauses, and clauses relating to releases or waivers of unmatured
claims or rights.

          We have made no examination of, and no opinion is given herein as to
the Trustee's or the Trust's title to or other ownership rights in, or the
existence of any liens, charges or encumbrances on, or adverse claims against,
any asset or property held by the Institutional Trustee or the Trust. We express
no opinion as to the creation, validity, attachment, perfection or priority of
any mortgage, security interest or lien in any asset or property held by the
Institutional Trustee or the Trust.

          We express no opinion as to the effect of events occurring,
circumstances arising, or changes of law becoming effective or occurring, after
the date hereof on the matters addressed in this opinion letter, and we assume
no responsibility to inform you of additional or changed facts, or changes in
law, of which we may become aware.

          We express no opinion as to any requirement that any party to the
Operative Documents (or any other persons or entities purportedly entitled to
the benefits thereof) qualify or register to do business in any jurisdiction in
order to be able to enforce its rights thereunder or obtain the benefits
thereof.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1. The Trust has been duly created and is validly existing in good
standing as a statutory trust under the Delaware Statutory Trust Act (12 Del. C.
Section 3801, et seq.) (the "Act"). All filings required under the laws of the
State of Delaware with respect to the creation and valid existence of the Trust
as a statutory trust have been made.


                                     B-2-3
<PAGE>
          2. Under the Declaration of Trust and the Act, the Trust has the trust
power and authority to (A) execute and deliver the Operative Documents, (B)
perform its obligations under such Operative Documents and (C) issue the Trust
Securities.

          3. The execution and delivery by the Trust of the Operative Documents,
and the performance by the Trust of its obligations thereunder, have been duly
authorized by all necessary trust action on the part of the Trust.

          4. The Declaration of Trust constitutes a legal, valid and binding
obligation of the Company, the Trustees and the Administrators, and is
enforceable against the Company, the Trustees and the Administrators, in
accordance with its terms.

          5. Each of the Operative Documents constitutes a legal, valid and
binding obligation of the Trust, enforceable against the Trust, in accordance
with its terms.

          6. The Capital Securities have been duly authorized for issuance by
the Declaration of Trust, and, when duly executed and delivered to and paid for
by the purchasers thereof in accordance with the Declaration of Trust, the
Subscription Agreement and the Placement Agreement, the Capital Securities will
be validly issued, fully paid and, subject to the qualifications set forth in
paragraph 8 below, nonassessable undivided beneficial interests in the assets of
the Trust and will entitle the Capital Securities Holders to the benefits of the
Declaration of Trust. The issuance of the Capital Securities is not subject to
preemptive or other similar rights under the Act or the Declaration of Trust.

          7. The Common Securities have been duly authorized for issuance by the
Declaration of Trust and, when duly executed and delivered to the Company as
Common Security Holder in accordance with the Declaration of Trust, will be
validly issued, fully paid and, subject to paragraph 8 below and Section 9.1(b)
of the Declaration of Trust (which provides that the Holder of the Common
Securities are liable for debts and obligations of Trust), nonassessable
undivided beneficial interests in the assets of the Trust and will entitle the
Common Security Holder to the benefits of the Declaration of Trust. The issuance
of the Common Securities is not subject to preemptive or other similar rights
under the Act or the Declaration of Trust.

          8. Under the Declaration of Trust and the Act, the Holders of the
Capital Securities, as beneficial owners of the Trust, will be entitled to the
same limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware. We note that the Holders of the Capital Securities and the Holder
of the Common Securities may be obligated, pursuant to the Declaration of Trust,
(A) to provide indemnity and/or security in connection with and pay taxes or
governmental charges arising from transfers or exchanges of Capital Security
Certificates and the issuance of replacement Capital Security Certificates, and
(B) to provide security or indemnity in connection with requests of or
directions to the Institutional Trustee to exercise its rights and powers under
the Declaration of Trust.

          9. Neither the execution, delivery and performance by the Trust of the
Operative Documents, nor the consummation by the Trust of any of the
transactions contemplated thereby, requires the consent or approval of, the
authorization of, the withholding of objection on the part of, the giving of
notice to, the filing, registration or qualification with, or the taking of any
other action in respect of, any governmental authority or agency of the State of
Delaware, other than the filing of the Certificate of Trust with the Secretary
of State (which Certificate of Trust has been duly filed).

          10. Neither the execution, delivery and performance by the Trust of
the Trust Documents, nor the consummation by the Trust of the transactions
contemplated thereby, (i) is in


                                     B-2-4
<PAGE>
violation of the Declaration of Trust or of any law, rule or regulation of the
State of Delaware applicable to the Trust or (ii) to the best of our knowledge,
without independent investigation, violates, contravenes or constitutes a
default under, or results in a breach of or in the creation of any lien (other
than as permitted by the Operative Documents) upon any property of the Trust
under any indenture, mortgage, chattel mortgage, deed of trust, conditional
sales contract, bank loan or credit agreement, license or other agreement or
instrument to which the Trust is a party or by which it is bound.

          11. Assuming that the Trust will not be taxable as a corporation for
federal income tax purposes, but rather will be classified for such purposes as
a grantor trust under Subpart E, Part I of Subchapter J of the Internal Revenue
Code of 1986, as amended, the Trust will not be subject to any tax, fee or
governmental charge under the laws of the State of Delaware.

          The opinions expressed in paragraph 4, 5, 6, 7 and 8 above are
subject, as to enforcement, to the effect upon the Declaration of Trust of (i)
bankruptcy, insolvency, moratorium, receivership, reorganization, liquidation,
fraudulent conveyance and transfer, and other similar laws relating to or
affecting the rights and remedies of creditors generally, (ii) principles of
equity, including applicable law relating to fiduciary duties (regardless of
whether considered and applied in a proceeding in equity or at law), and (iii)
the effect of applicable public policy on the enforceability of provisions
relating to indemnification or contribution.

          In basing the opinions set forth herein on "our knowledge," the words
"our knowledge" signify that no information has come to the attention of the
attorneys in the firm who are directly involved in the representation of the
Trust in this transaction that would give us actual knowledge that any such
opinions are not accurate. Except as otherwise stated herein, we have undertaken
no independent investigation or verification of such matters.

          We consent to your relying as to matters of Delaware law upon this
opinion in connection with the Placement Agreement. We also consent to Lewis,
Rice & Fingersh, L.C.'s and Stinson Morrison Hecker LLP's relying as to matters
of Delaware law upon this opinion in connection with opinions to be rendered by
them on the date hereof pursuant to the Placement Agreement. Except as stated
above, without our prior written consent, this opinion may not be furnished or
quoted to, or relied upon by, any other Person for any purpose.

                                Very truly yours,

Ladies and Gentlemen:

     We have acted as special tax counsel to Exchange National Bancshares, Inc.
and to Exchange National Statutory Trust II in connection with the proposed
issuance of (i) Fixed/Floating Rate Capital Securities, liquidation amount
$1,000.00 per Capital Security (the "Capital Securities") of Exchange National
Statutory Trust II, a statutory business trust created under the laws of
Delaware (the "Trust"), pursuant to the terms of the Amended and Restated
Declaration of Trust dated as of the date hereof by Exchange National
Bancshares, Inc., a Missouri corporation (the "Company"), Wilmington Trust
Company, as Delaware trustee, Wilmington Trust Company, as institutional
trustee, and Kathleen Bruegenhemke, James E. Smith and David T. Turner, as
Administrators (the "Trust Agreement"), (ii) Junior Subordinated Deferrable
Interest Debentures (the "Corresponding Debentures") of the Company issued
pursuant to the terms of an Indenture dated as of the date hereof from the
Company to Wilmington Trust Company, as trustee (the "Indenture"), which
Debentures are to be sold by the Company to the Trust, and (iii) the Guarantee
Agreement of the Company with respect to the Capital Securities dated as of the
date hereof (the "Guarantee") between the Company and Wilmington Trust Company,
as guarantee trustee. The Capital Securities and the Corresponding Debentures
are to be issued as contemplated by the Offering Circular (the "Offering
Circular") dated March 9, 2005 prepared by Preferred Term Securities XVII, Ltd.,
an entity formed under the Companies Law of the Cayman Islands, and Preferred
Term Securities XVII, Inc., a Delaware corporation.

     We have examined originals or copies, certified or otherwise identified to
our satisfaction, of documents, corporate records and other instruments as we
have deemed necessary or appropriate for purposes of this opinion including (i)
the Offering Circular, (ii) the Indenture, (iii) the form of the Corresponding
Debentures attached as an exhibit to the Indenture, (iv) the Trust Agreement,
(v) the Guarantee, and (vi) the form of Capital Securities Certificate attached
as an exhibit to the Trust Agreement (collectively the "Documents").
Furthermore, we have relied upon certain representations made by the Company and
upon the opinion of Richards, Layton & Finger, P.A. as to certain matters of
Delaware law. In such examination, we have assumed the authenticity of all
documents submitted to us


                                     B-3-1
<PAGE>
as originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies, the authenticity of the originals of such
latter documents, the genuineness of all signatures and the correctness of all
representations made therein. We have further assumed that there are no
agreements or understandings contemplated therein other than those contained in
the Documents.

     Based upon the foregoing, and assuming (i) that the final Documents will be
substantially identical to the forms examined, (ii) full compliance with all the
terms of the final Documents, and (iii) the accuracy of representations made by
the Company and delivered to us, we are of the opinion that:

     (a)  The Corresponding Debentures will be classified as indebtedness of the
          Company for U.S. federal income tax purposes.

     (b)  The Trust will be characterized as a grantor trust and not as an
          association taxable as a corporation for U.S. federal income tax
          purposes.

     The opinions expressed above are based on existing provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), existing Treasury
regulations, published interpretations by the Internal Revenue Service of the
Code and such Treasury regulations, and existing court decisions, any of which
could be changed at any time. Any such changes may or may not be retroactively
applied, and may result in federal income tax consequences that differ from
those reflected in the opinions set forth above. We note that there is no
authority directly on point dealing with securities such as the Capital
Securities or with transactions of the type described herein, and that the
authorities on which this opinion is based are subject to various
interpretations. Further, you should be aware that opinions of counsel have no
official status and are not binding on the Internal Revenue Service or the
courts. Accordingly, we can provide no assurance that the interpretation of the
federal income tax laws set forth in our opinions will prevail if challenged by
the IRS in an administrative or judicial proceeding.

     We have also assumed that each transaction contemplated herein will be
carried out strictly in accordance with the Documents. Any variance in the facts
may result in Federal income tax consequences that differ from those reflected
in the opinions set forth above.

     Additionally, we undertake no obligation to update this opinion in the
event there is either a change in the legal authorities, in the facts (including
the taking of any action by any party to any of the transactions described in
the Documents relating to such transactions) or in the Documents on which this
opinion is based, or an inaccuracy in any of the representations upon which we
have relied in rendering this opinion.

     We express no opinion with respect to any matter not specifically addressed
by the foregoing opinions, including state or local tax consequences, or any
federal, state, or local issue not specifically referred to and discussed above
including, without limitation, the effect on the matters covered by this opinion
of the laws of any other jurisdiction.

     This letter is delivered for the benefit of the specified addressees and
may not be relied upon by any other person. No portion of this letter may be
quoted or otherwise referred to in any document or delivered to any other person
or entity without the express written consent of Lewis, Rice & Fingersh, L.C.

     RE: REPRESENTATIONS CONCERNING THE ISSUANCE OF JUNIOR SUBORDINATED
         DEFERRABLE INTEREST DEBENTURES (THE "DEBENTURES") TO EXCHANGE NATIONAL
         STATUTORY TRUST II (THE "TRUST") AND SALE OF TRUST SECURITIES (THE
         "TRUST SECURITIES") OF THE TRUST

Ladies and Gentlemen:

     In accordance with your request, Exchange National Bancshares, Inc. (the
"Company") hereby makes the following representations in connection with the
preparation of your opinion letter as to the United States federal income tax
consequences of the issuance by the Company of the Debentures to the Trust and
the sale of the Trust Securities.

     Company hereby represents that:

     1. The sole assets of the Trust will be the Debentures, any interest paid
on the Debentures to the extent not distributed, proceeds of the Debentures, or
any of the foregoing.

     2. The Company intends to use the net proceeds from the sale of the
Debentures for general corporate purposes.

     3. The Trust was not formed to conduct any trade or business and is not
authorized to conduct any trade or business. The Trust exists for the exclusive
purposes of (i) issuing and selling the Trust Securities, (ii) using the
proceeds from the sale of Trust Securities to acquire the Debentures, and (iii)
engaging only in activities necessary or incidental thereto.

     4. The Trust was formed to facilitate direct investment in the assets of
the Trust, and the existence of multiple classes of ownership is incidental to
that purpose. There is no intent to provide holders of such interests in the
Trust with diverse interests in the assets of the Trust.

     5. The Company intends to create a debtor-creditor relationship between the
Company, as debtor, and the Trust, as a creditor, upon the issuance and sale of
the Debentures to the Trust by the Company. The Company will (i) record and at
all times continue to reflect the Debentures as indebtedness on its separate
books and records for financial accounting purposes, and (ii) treat the
Debentures as indebtedness for all United States tax purposes.

     6. During each year, the Trust's income will consist solely of payments
made by the Company with respect to the Debentures. Such payments will not be
derived from the active conduct of a financial business by the Trust. Both the
Company's obligation to make such payments and the measurement of the amounts
payable by the Company are defined by the terms of the Debentures. Neither the
Company's obligation to make such payments nor the measurement of the amounts
payable by the Company is dependent on income or profits of Company or any
affiliate of the Company.

     7. The Company expects that it will be able to make, and will make, timely
payment of amounts identified by the Debentures as principal and interest in
accordance with the terms of the Debentures with available capital or
accumulated earnings.


                                      B-3-3

     8. The Company presently has no intention to defer interest payments on the
Debentures, and it considers the likelihood of such a deferral to be remote
because, if it were to exercise its right to defer payments of interest with
respect to the Debentures, it would not be permitted to declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any capital stock of the Company or any
affiliate of the Company (other than payments of dividends or distributions to
the Company) or 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 of the Company that rank pari passu in all respects with or junior in
interest to the Debentures, in each case subject to limited exceptions stated in
Section 2.11 of the Indenture to be entered into in connection with the issuance
of the Debentures.

     9. Immediately after the issuance of the Debentures, the debt-to-equity
ratio of the Company (as determined for financial accounting purposes, but
excluding deposit liabilities from the Company's debt) will be within standard
depository institution industry norms and, in any event, will be no higher than
four to one (4 : 1).

     10. To the best of our knowledge, the Company is currently in compliance
with all federal, state, and local capital requirements, except to the extent
that failure to comply with any such requirements would not have a material
adverse effect on the Company and its affiliates.

     11. The Company will not issue any class of common stock or preferred stock
senior to the Debentures during their term.

     12. The Internal Revenue Service has not challenged the interest deduction
on any class of the Company's subordinated debt in the last ten (10) years on
the basis that such debt constitutes equity for federal income tax purposes.

     The above representations are accurate as of the date below and will
continue to be accurate through the issuance of the Trust Securities, unless you
are otherwise notified by us in writing. The undersigned understands that you
will rely on the foregoing in connection with rendering certain legal opinions,
and possesses the authority to make the representations set forth in this letter
on behalf of the Company.

                                        Very truly yours,

                                        EXCHANGE NATIONAL BANCSHARES, INC.
