the common stock of Acquisition Company; and

     B.   USB is the beneficial and record owner of one hundred

     C.   The Shareholders are the beneficial or record owners of
approximately 91.6% of the issued and outstanding common stock of
USB ("USB Common Stock"); and

     D.   Exchange desires to acquire one hundred percent (100%)
of the issued and outstanding shares of USB Common Stock; and
     
     E.   The Shareholders desire to sell their shares of USB

and

     H.   The Exchange Entities, Sellers and Hockenberry desire

<PAGE>



                           ARTICLE I
                  THE ACQUISITION TRANSACTION

     1.01 The Acquisition Transaction.  Subject to the terms and
conditions of this Agreement, Acquisition Company will merge with
and into USB (the "Merger") under the terms set forth in the
related Merger Agreement (the "Merger Agreement") to be executed
prior to the Closing Date by and between USB and Acquisition
Company in substantially the form set forth in Exhibit A to this
Agreement, whereby the shareholders of USB will receive the
consideration as set forth in this Agreement and the Merger
Agreement.  Exchange hereby undertakes to pay and to execute and
deliver or cause to be paid and delivered all cash and promissory
notes of Exchange required to be paid and delivered to the
shareholders of USB pursuant to this Agreement and the Merger
Agreement.

          The shareholders of USB will receive the amount of cash
and promissory notes of Exchange that will equal their respective
percentage ownership interest in the outstanding shares of USB
Common Stock as of the Effective Time multiplied by the total
amount of consideration payable in the Merger as set forth in
Section 1.07 of this Agreement (as defined therein, the "Merger
Consideration"); provided, however, that only the shareholders
designated in Section 1.07(a)(i) shall receive both cash and
promissory notes in the Merger and the amount of cash to be paid
to each USB shareholder shall be proportionately adjusted so that
the total consideration received by each, valuing the promissory
notes at face value, shall be in proportion to their respective
stock interests.

          Upon consummation of the Merger, the separate corporate
existence of Acquisition Company will cease and USB will be the
surviving corporation in the Merger (the "Surviving
Corporation").

     1.02 Closing.  The closing (the "Closing") of the Merger,
unless the parties hereto shall otherwise mutually agree, shall
take place at the offices of Exchange's counsel in Kansas City,
Missouri, at 10:00 a.m., local time, on a date designated by
Exchange (the "Closing Date"), which shall be at least two (2)
business days and not more than ten (10) business days following
the last to occur of the following events:  (a) the receipt of
the requisite approval of the Merger by the shareholders of USB
as set forth in Section 2.02 of this Agreement and (b) the
approval of the Merger by the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board"), Division of Finance
of the Department of Economic Development ("Missouri Director of
Finance") and any other bank regulatory agency that may be
necessary or appropriate, and the expiration of any required
waiting period.

     1.03 Method of Effecting Merger and Effective Time.  On the
Closing Date, the parties hereto will cause the Merger to be
consummated by delivering to the Missouri Secretary of State, for
filing, copies of the Merger Agreement and related articles of
merger in such form as is required by, and executed in accordance
with, the relevant provisions of Chapter 351 of the Missouri
Revised Statutes (the "Missouri Corporate Law").  The Merger
shall be effective on the <PAGE> date and at the time (the "Effective
Time") that the Missouri Secretary of State issues a certificate
of merger with respect to the Merger.

     1.04 Articles and Bylaws.  The articles of incorporation and
bylaws of USB in effect immediately prior to the Effective Time
shall be the articles of incorporation and bylaws of the
Surviving Corporation, in each case until amended in accordance
with their respective provisions and applicable law.

     1.05 Board of Directors and Officers.

          (a)  At the Effective Time, the members of the Board of
Directors of the Surviving Corporation and the terms of these
directors shall be as designated by Exchange immediately prior to
the Effective Time.

          (b)  At the Effective Time, the officers of the
Surviving Corporation shall be the persons designated by Exchange
immediately prior to the Effective Time, and such persons will
serve in their designated offices, thereafter, until their
respective successors are duly elected and qualified.

     1.06 Additional Actions.  If, at any time after the
Effective Time, the Surviving Corporation shall consider or be
advised that any further deeds, assignments or assurances in law
or any other acts are necessary or desirable to (a) vest, perfect
or confirm, of record or otherwise, in the Surviving Corporation
its right, title or interest in, to, or under any of the rights,
properties or assets of USB, or (b) otherwise carry out the
purposes of this Agreement or the Merger Agreement, USB and its
officers and directors shall be deemed to have granted to the
Surviving Corporation an irrevocable power of attorney to execute
and deliver all such deeds, assignments or assurances in law and
to do all acts necessary or proper to vest, perfect or confirm
title to and possession of such rights, properties or assets in
the Surviving Corporation and otherwise to carry out the purposes
of this Agreement or the Merger Agreement, and the officers and
directors of the Surviving Corporation are authorized in the name
of USB or otherwise to take any and all such action.

     1.07 Payment and Delivery of Consideration.

          (a)  At the closing, Exchange will pay to the
shareholders of USB consideration equal to $20,100,000 (subject
to adjustment pursuant to Section 1.07(c) hereof) (the "Merger
Consideration") in exchange for 100% of the USB Common Stock. 
Such Merger Consideration shall be paid as follows:

          (collectively, the "Notes", each, a "Note") to be
          executed and delivered by Exchange in favor of each of
          the designated shareholders, respectively.    The Notes
          shall be in the form attached as Exhibit B hereto and
          shall bear interest at a rate of 7% per annum, shall,

          interest only until maturity, shall provide for
          quarterly payments of accrued interest and shall, at

          Date, permit prepayment of principal and accrued
          interest by Exchange upon 60 days' notice to the
          holders of such Notes.  The Notes shall be secured by
          all of the Bank Common Stock pursuant to a Stock Pledge
          Agreement in the form attached as Exhibit B1 hereto;
          provided, however, that the holders of such Notes may,
          anytime at their option, upon 30 days' notice, demand
          that Exchange obtain and substitute in lieu of such
          security interest an irrevocable standby letter of
          credit in the face amount of the Notes, having an
          expiration date at least thirty (30) days after the
          maturity date of the Notes and otherwise reasonably
          acceptable in form and substance to Exchange and such
          holders, the cost of which shall be borne by the
          holders of the Notes in an amount not to exceed 0.5%
          per annum; and

               (ii) The balance of the Merger Consideration in
          cash.  

The shareholders designated in Section 1.07(a)(i) above shall
have the right to reallocate the total consideration to be
received by each such shareholder between cash and the principal
amount of the Note in favor of such shareholder by giving notice
thereof to Exchange at least 30 days prior to Closing.

          (b)  At the Closing, Exchange shall deliver to each of
the shareholders of USB such amount of cash and Notes as such
shareholder shall be entitled to receive pursuant to Sections
1.01 and 1.07(a) hereof, and each of the shareholders of USB
shall surrender to the Surviving Corporation certificates
representing the total number of shares of USB Common Stock owned
by such shareholder.

          (c)  The Merger Consideration shall be adjusted as
follows: 

               (i)  the Merger Consideration shall be decreased
          by an amount equal to the parent company indebtedness
          and other liabilities not taken into account in
          computing 1997 consolidated results of operations of
          USB as of the last day of the month next preceding the
          month in which the Closing occurs; and 

               (ii) the Merger Consideration shall be increased
          (or decreased, if a negative number) in an amount equal
          to (a) USB's consolidated results of operations,
          without any adjustment for taxes other than taxes
          actually incurred and not passed through to
          shareholders pursuant to Subchapter S, excluding
          realized and unrealized securities gains and losses
          ("Net Income"), for the period from <PAGE> January 1, 1997
          through the earlier of September 30, 1997 or the last
          day of the month next preceding the month in which the
          Closing occurs, as determined by USB's accountants and
          subject to reasonable approval of KPMG Peat Marwick
          LLP, and (b) forty percent (40%) of Net Income (if any)
          for the period from October 1, 1997 through the earlier
          of December 31, 1997 or the last day of the month next
          preceding the month in which the Closing occurs, less
          (x) dividends declared or paid by USB after December
          31, 1996 and prior to Closing, (y) any principal
          repayments of USB's indebtedness made after December
          31, 1996 and prior to closing and (z) any expenses
          related to negotiation and consummation of the Merger
          which may be paid or incurred by USB or the Bank; and

               (iii)     the Merger Consideration shall be
          increased (or decreased, if a negative number) in an
          amount equal to USB's consolidated results of
          operations, after taxes, excluding realized and
          unrealized securities gains and losses, for the period
          from January 1, 1998 through the earlier of March 31,
          1998 or the last day of the month next preceding the
          month in which the Closing occurs, as determined by
          USB's accountants and subject to reasonable approval of
          KPMG Peat Marwick LLP, less (x) dividends paid by USB
          after December 31, 1996 and prior to Closing (y) any
          principal repayments of USB's indebtedness made after
          December 31, 1996 and prior to Closing and (z) any
          expenses related to negotiation and consummation of the
          Merger which may be paid or incurred by USB or the
          Bank.  

Any negative adjustment of the Merger Consideration shall be an
adjustment to the amount payable by Notes pursuant to Section
1.07(a)(ii).

     1.08 Dissenting Shares.

          (a)  "Dissenting Shares" means any shares of USB Common
Stock held by any holder who becomes entitled to payment of the
value of such shares under Section 351.455 of the Missouri
Revised Statutes ("Section 351.455").  Any holders of Dissenting
Shares shall be entitled to payment for such shares only to the
extent permitted by and in accordance with the provisions of such

          (b)  The allowance for loan losses contained in the
balance sheet of the Bank as of March 31, 1997 was established in
accordance with the past practices and experiences of the <PAGE> Bank
and such allowance was adequate in all material respects under
applicable regulatory requirements to provide for possible losses
on loans and leases (including, without limitation, accrued
interest receivable) and credit commitments (including, without
limitation, stand-by letters of credit) as of the date of such
balance sheet; provided, however, nothing herein contained shall
be construed as a warranty of the collectibility of any loan or
that the actual loan losses incurred will not exceed the amount
of the allowance.  The reserve for loan losses as of the Closing
Date shall be equal to or greater than the amount of the reserve
for loan losses reflected on the financial statements of USB as
of March 31, 1997.

          (c)  Schedule 2.12(c) sets forth as of the date of this
Agreement all assets classified as real estate acquired through
foreclosure, including in-substance foreclosed real estate ("Non-
Performing Assets").

     2.13 Taxes.  

          (a)  Each of USB and the Bank has timely filed or will
timely file (including all extensions) all tax returns required
to be filed at or prior to the Closing Date ("Union Returns"). 
To the best knowledge of Sellers, each of USB and the Bank has
paid, or has set up adequate reserves on the Union Financial
Statements for the payment of, all taxes required to be paid in
respect of the periods covered by such returns and has set up
adequate reserves on the Union Financial Statements for the
payment of all taxes anticipated to be payable in respect of the
period subsequent to the last of said periods (treating for this
purpose the Closing Date as the last day of an applicable period,
whether or not it is in fact the last day of a taxable period). 
Neither USB nor the Bank will have any liability for any such
taxes in excess of the amounts so paid or reserves so
established, and no deficiencies for any tax, assessment or
governmental charge have been proposed, asserted or assessed
(tentatively or definitively) against USB or the Bank which would
not be covered by existing reserves.  To the best knowledge of
Sellers, neither USB nor the Bank is delinquent in the payment of
any tax, assessment or governmental charge, nor has it requested
any extension of time within which to file any tax returns in
respect of any fiscal year which have not since been filed and no
requests for waivers of the time to assess any tax are pending. 
The federal, state and foreign income tax returns of each of USB
and the Bank have not been audited by the Internal Revenue
Service (the "IRS") or the state or foreign taxing authority
during the previous seven years.  Neither USB nor the Bank has
made any election under Income Tax Regulation Sections 1.1502-
33(d)(3) or 1.1552-1(c), each of which relates to the allocation
of the consolidated federal income tax liability, and, other than
the Tax Sharing Agreement dated August 9, 1984 by and between USB
and the Bank (the "Tax Sharing Agreement"), neither USB nor the
Bank is a party to or bound by any tax indemnity, tax sharing or
tax allocation agreement, or any other contractual obligation to
pay or contribute to the tax obligations of any other person. 
There is no deficiency or presently pending refund litigation or
matter in controversy with respect to Union Returns.  Neither USB
nor the Bank has extended or waived any statute of limitations on
the assessment of any tax due that is currently in effect.

          (b)  Neither Sellers' election to convert USB to
Subchapter S status nor the termination of such status as a
result of the transactions contemplated by this Agreement and the


<PAGE> 



Merger Agreement shall cause USB or the Bank to incur any
liability for income taxes which shall  not be accrued or paid
during the period from January 1, 1997 through the earlier of
September 30, 1997 or the last day of the month next preceding
the month in which the Closing occurs.  

     2.14 Material Adverse Change.  Since March 31, 1997, there
has been no material adverse change in the financial condition,
results of operations, business, assets, prospects or operations
of USB or the Bank taken as a whole, other than changes in
banking laws or regulations, or interpretations thereof, or other
conditions that affect the banking industry generally, or changes
in the general level of interest rates.

     2.15 Litigation and Other Proceedings.  Except as set forth

to any order, judgment or decree, except for matters which, in
the aggregate, will not have, or cannot reasonably be expected to
have, a material adverse effect on the business, financial
condition, results of operations or prospects of USB or the Bank. 
Without limiting the generality of the foregoing, except as set
forth in Schedule 2.15, there are no actions, suits or
proceedings pending or, to the best knowledge of the Sellers,
threatened against USB or the Bank or any of their respective
officers or directors by any shareholder of USB or the Bank (or
any former shareholder) or involving claims under the Community
Reinvestment Act of 1977, Bank Secrecy Act, the fair lending laws
or any other laws applicable to the Bank.

     2.16 Compliance with Laws.

          (a)  To the best knowledge of the Sellers, USB and the
Bank have all permits, licenses, authorizations, orders and
approvals of, and have made all filings, applications and
registrations with, all Regulatory Authorities that are required
in order to permit them to own or lease their respective
properties and assets and to carry on their respective businesses
as presently conducted; all such permits, licenses, certificates
of authority, orders and approvals are in full force and effect
and no suspension or cancellation of any of them is threatened;
and, to the best knowledge of Sellers, all such filings,
applications and registrations are current; in each case except
for permits, licenses, authorizations, orders, approvals,
filings, applications and registrations the failure to have (or
have made) would not have a material adverse effect on the
financial condition, results of operations, business or prospects
of USB or the Bank.

          (b)  Each of USB and the Bank has complied with all

statements pertaining to the conduct of a banking, deposit-
taking, lending or related business, or to the exercise of trust

be expected to have a material adverse effect on the financial
condition, results of operations, business or prospects of USB or
the Bank, and neither USB nor the Bank is in default <PAGE> under, and
no event has occurred which, with the lapse of time or notice or
both, could result in the default under, the terms of any

below) of USB or the Bank (whether directly or as a consequence
of such Property being part of the investment portfolio of the

related materials, including, without limitation, asbestos, PCBs,
pesticides, herbicides and any other substance or waste that is

has been stored, disposed of, placed, or used in the construction
thereof.  "Property" shall include all property (real or
personal, tangible or intangible) owned or controlled by USB or
the Bank, including, without limitation, property under
foreclosure and property in which any venture capital or similar
unit of the Bank has an ownership or possessory interest.  No
claim, action, suit or proceeding is pending against USB or the
Bank relating to the Property before any court or other
Regulatory Authority or arbitration tribunal relating to
Hazardous Substances, pollution or the environment, and there is
no outstanding judgment, order, writ, injunction, decree or award
against or affecting USB or the Bank with respect to the same. 
Except for statutory or regulatory restrictions of general
application, no Regulatory Authority has placed any restriction
on the business of USB or the Bank which reasonably could be
expected to have a material adverse effect on the condition of
USB or the Bank.

          (d)  Since December 31, 1993, neither USB nor the Bank
has received any notification or communication which has not been
favorably resolved from any Regulatory Authority (i) asserting
that USB or the Bank is not in substantial compliance with any of
the statutes, regulations or ordinances that such Regulatory
Authority enforces, except with respect to matters which (A) are

to have a material adverse effect on the condition of the Bank,

governmental authorization that is material to the condition of
the Bank including, without limitation, the Bank's status as an

Bank, including, without limitation, any restriction on the
payment of dividends.  No such cease and desist order, agreement
or memorandum of understanding or other agreement is currently in

contrary, the Exchange Due Diligence Review shall not limit,
restrict or preclude, or be construed to limit, restrict or
preclude, Exchange, at any time or from time to time thereafter,
from conducting further such reviews or from exercising any
rights available to it hereunder as a result of the existence or
occurrence prior to the Exchange Due Diligence Period of any
event or condition which was not detected in the Exchange Due
Diligence Review by Exchange and which would constitute a breach
of any material representation, warranty or agreement of USB or
the Bank under this Agreement.

     5.02 Regulatory Matters.  Each of the parties hereto shall
cooperate and use their respective best efforts to prepare all
documentation, to effect all filings, and to obtain all permits,
consents, approvals and authorizations of all third parties and

     5.03 Shareholder Approvals.  USB shall call a special
meeting of its shareholders to be held as soon as is reasonably
practicable for the purpose of voting upon this Agreement and the

for the approval and adoption of the matters contemplated hereby. 
Each of the Shareholders agrees to vote all shares of USB Common

Consideration that such Shareholder would be entitled to receive

confer on a regular and frequent basis with representatives of
the other party.  Each party shall promptly notify the other
parties of the following events immediately upon learning of the
occurrence thereof, describing the same and, if applicable, the

material change in its business, financial condition, results of
operations or prospects; (c) the issuance or commencement of any

of such Real Property consistent with ASTM practices (excluding
space in retail or similar establishments leased by the Bank for
automatic teller machines or bank branch facilities where the
space leased comprises less than 20% of the total space leased to
all tenants of such property).  If required by the phase one
report with respect to any parcel of real property referred to

phase two investigation report on such designated parcels as soon
as practicable.  The Exchange Entities shall have fifteen (15)
business days from the receipt of any such phase two
investigation report to notify the Sellers of any dissatisfaction
with the contents of such report.  If the Exchange Entities are
dissatisfied with the contents of such report due to the fact
that: (i) the estimated costs of all remedial or other corrective
actions or measures with regard to the real property referred to
above required by applicable law (the "Remediation Costs") exceed
$250,000 in the aggregate, as reasonably estimated by an
environmental expert retained for such purpose by the Exchange
Entities, or (ii) the costs of such remedial or other corrective
actions cannot be reasonably estimated by such expert to be
$250,000 or less with any reasonable degree of certainty, then
the Exchange Entities, at its sole discretion, shall have the
right to terminate this Agreement upon <PAGE> fifteen (15) days' notice
to Sellers unless Sellers, upon receipt of such notice, elect
within fifteen (15) days thereafter to reduce the Merger
Consideration by an amount equal to the Remediation Costs (or in
the case of an inability to estimate such costs, by an amount
equal to the actual costs of such required remedial or other
corrective actions), in which case the Merger Consideration shall
be so reduced and this Agreement shall not be terminated pursuant
to this Section. 

     5.06 Expenses.  Each party hereto shall bear its own costs
and expenses incident to preparing, entering into and carrying
out this Agreement, the Merger Agreement and the transactions
contemplated hereby and thereby, whether or not the Merger shall

terms and conditions herein provided, each of the parties hereto
agrees to use its best efforts to take, or cause to be taken, all
action, and to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by
this Agreement and the Merger Agreement as expeditiously as

proposed press release or other proposed public disclosure of
matters related to this Agreement, the Merger Agreement or any of
the transactions contemplated hereby or thereby.  Unless in the
reasonable opinion of Exchange's counsel an announcement is
required by the securities laws, no announcement shall be made by
either party without the consent of the other party unless and
until either: (i) the Due Diligence Period shall have expired,
and (ii) Exchange has notified USB that Exchange waives its
termination right pursuant to Section 7.01(d) and Section
7.01(f).  

     5.09 Indemnification of USB and The Bank's Directors,
Officers and Employees.  

          (a)  Exchange agrees that the Merger shall not affect
or diminish any of the Bank's or Surviving Corporation's (with
respect to USB and the Bank) duties and obligations of
indemnification existing at the Effective Time of the Merger in
favor of employees, agents, director or officers of the Bank or
Surviving Corporation arising by virtue of its charter or Bylaws
in the form in effect at the date hereof or arising by operation
of law or arising by virtue of any contract, resolution, or other
agreement or document existing at the date hereof, and such
duties and obligations shall continue in full force and effect
for so long as they would otherwise survive and continue in full
force and effect.  To the extent that the Bank's or Surviving
Corporation's existing directors' and officers' liability
insurance policy would provide coverage for any action or
omission occurring prior to the Effective Time, the Sellers agree
to give proper notice to the <PAGE> insurance carrier and to the
Exchange Entities of a potential claim thereunder so as to
preserve the Bank's or Surviving Corporation's rights to such
insurance coverage.

          (b)  If after the Effective Time, the Surviving
Corporation or the Bank or any of their respective successors or
assigns (i) shall consolidate with or merge into any other
corporation or entity and shall not be the continuing or
surviving corporation or entity of such consolidation or merger
or (ii) shall transfer all or substantially all of its properties
and assets to any individual, corporation or entity, that in each
such case, proper provisions shall be made so that the successors
and assigns of this Surviving Corporation or the Bank shall
assume any remaining obligations of such surviving corporation or
the Bank set forth in this Section 5.09.  If the Bank or the
Surviving Corporation shall liquidate, dissolve or otherwise wind
up its business, then the Exchange Entities shall indemnify,
defend and hold harmless each Indemnified Party to the same
extent and on the same terms that the Surviving Corporation or
the Bank was so obligated pursuant to this Section 5.09.

          (c)  For a period of three (3) years after the
Effective Time, Exchange will continue the Bank's and the
Surviving Corporation's directors' and officers' liability
insurance coverage with respect to actions occurring prior to the
Effective Time.

     5.10 Employee Benefit Plans.

          (a)  Following the Effective Time, the Exchange
Entities shall cause the Surviving Corporation to honor in
accordance with their terms all employment, severance and other
compensation contracts set forth on Schedule 5.10 between the
Bank and any current or former director, officer, employee or
agent thereof, and all provisions for vested benefits or other
vested amounts earned or accrued through the Effective Time under
the Sellers Employee Plans.

          (b)  The provisions of any plan, program or arrangement
providing for the issuance or grant of any other interest in
respect of the capital stock of the Bank or USB shall be
terminated as of the Effective Time, so that following the
Effective Time no person shall have any right to acquire any
securities of the Bank or USB.

          (c)  Unless otherwise agreed by USB and Exchange, as of
the Effective Time USB and Exchange shall take the following
actions to the extent practicable:

               (i)  By amendment to the Union State Bank & Trust
          of Clinton Profit Sharing Plan, which shall be
          effective as of the Effective Time, all participants
          shall be 100% vested, and such Plan shall be merged
          into the Exchange Profit Sharing Trust or a new Bank
          Profit Sharing Plan  or the Union State Bank & Trust of
          Clinton Profit Sharing Plan shall be frozen.  

               (ii) The employees of Bank who continue to work
          for the Bank after the Effective Time shall participate
          in the Exchange Profit Sharing Plan or a Bank Profit
          Sharing Plan under the terms of such Plan as amended
          from time to time.  <PAGE> The service of such employees while
          employed by Bank prior to the Effective Time shall be
          counted for eligibility and vesting purposes but not
          for benefit accrual purposes in such Plan.  The level
          of contribution to the Exchange Profit Sharing Plan or
          a Bank Profit Sharing Plan for the benefit of the Bank
          employees need not be the same as that for other
          Exchange employees, but shall not be less than Bank's
          current contribution to the Union State Bank & Trust of
          Clinton Profit Sharing Plan.

               (iii)     Whether and when the employees of Bank
          who continue to work for the Bank after the Effective
          Time shall participate in the Exchange Pension Plan as
          amended from time to time or a new Bank Pension Plan,

          legal requirements, be determined by Exchange after the
          Effective Time.

               (iv) Exchange shall, with respect to each employee
          of the Bank who continues to work for the Bank after
          the Effective Time, provide the benefits described in
          this Section 5.10(c)(iv).  Subject to the right of
          subsequent amendment, modification or termination in
          Exchange's sole discretion, each such employee shall be
          entitled to receive fringe benefits on terms no less
          favorable to such employees than provided by their
          current terms of employment with the Bank. 

     5.11 Consulting/Noncompetition Agreements.  At the Closing,
Exchange will enter into a Consulting/Noncompetition Agreement
with each of Wetzel and Thomason in the form attached hereto as

will continue to serve on the Board of Directors of the Bank, <PAGE> and
Exchange represents that its present intention is to continue to
elect each of the Individual Shareholders as directors of the
Bank so long as they are able to serve in such capacity.  Each of
the Individual Shareholders agrees, if elected, to serve as a
director of the Bank, if able to do so, for a period of six years
following the Closing.  

     5.16 Notes Held Solely for Investment Purposes.  The
Individual Shareholders agree and acknowledge that they will hold
their respective Notes solely for purposes of investment and
without any intent to distribute such Notes.

     5.17 Shareholders Purchase of Property.  On or before the
Effective Date, Shareholders shall be entitled to purchase from
the Bank that portion of the real property and improvements
thereon located at 125 N. Main Street, Clinton, Missouri

contained or referred to herein, give prompt written notice
thereof to Sellers and use its best efforts to prevent or
promptly remedy the same.

time prior to the Closing Date, whether before or after approval
by the shareholders of USB,

          (a)  by mutual consent by the Board of Directors of
Exchange and the Board of Directors of USB;

          (b)  by the Board of Directors of Exchange or the Board
of Directors of USB hereto at any time after March 31, 1998 if
the Merger shall not theretofore have been consummated;



<PAGE> 



          (c)  by the Board of Directors of Exchange or the Board
of Directors of USB if the Federal Reserve, the Missouri Director
of Finance or any other federal and/or state regulatory agency
whose approval is required for the consummation of the Merger
shall have denied approval of such transaction;

          (d)  by the Board of Directors of Exchange, at any time
prior to the completion of the Exchange Due Diligence Period, in
the event any situation, event, circumstance or other matter
shall come to the attention of Exchange during the course of 
Exchange Due Diligence Review conducted pursuant to Section
5.01(b) hereof which Exchange shall, in its sole discretion,
determine to be of a type or nature which causes it to believe
that proceeding with the Merger is not in the best interests of
Exchange or its shareholders;

          (e)  by the Board of Directors of Exchange, on the one
hand, or by the Board of Directors of USB, on the other hand, in
the event of a breach by the other of any representation,
warranty or agreement contained in this Agreement, which breach
is of such a magnitude as to be materially adverse to the
business, financial condition, results of operations or prospects
of the breaching party and its subsidiaries taken as a whole and
is not cured after 30 days' written notice thereof is given to
the party committing such breach or waived by such other party or
parties;

          (f)  by the Board of Directors of Exchange pursuant to
and in accordance with the provisions of Section 5.05 hereof; or

          (g)  by the Board of Directors of Exchange in the event
that it reasonably determines that a material adverse change in
the financial position or business of USB or the Bank shall have
occurred or if USB or the Bank shall have suffered a material
loss or damage to any of their properties or assets, which loss
or damage materially adversely affects or impairs their ability
to conduct their businesses, or if any suit or similar proceeding
shall be instituted or threatened by any party which in the
opinion of counsel to Exchange may result in the restraint,
prohibition or obtaining of damages or other relief in connection
with this Agreement or the consummation of the transactions
contemplated thereby; or

     7.02 Effect of Termination.  In the event of termination of
this Agreement as provided in Section 7.01 above, this Agreement
shall forthwith become void and without further effect and there
shall be no liability on the part of any party hereto or the
respective officers and directors of each, except as set forth in
the second sentence of Section 5.01(a), Section 5.06 and Article
VIII, and, except that no termination of this Agreement pursuant
to subsection (e) of Section 7.01 shall relieve the non-
performing party of any liability to any other party hereto
arising from the breach or non-performance of any warranty or
covenant herein, after the giving of notice and the opportunity
to cure.  The parties recognize that the remedies at law of
Exchange for a breach by any Seller are inadequate and that in
addition to other remedies, Exchange shall be entitled to
specific performance in other equitable remedies. 
Notwithstanding the foregoing, in the event that <PAGE> this Agreement
is terminated pursuant to Section 7.01(e) hereof on the account
of a willful breach of any of the representations and warranties
set forth herein or any breach of any of the agreements set forth
herein, then the non-breaching party shall be entitled to recover
appropriate damages from the breaching party; provided, however,
that no party shall be liable for a breach of such representation
or warranty unless such party had actual knowledge of the
inaccuracy or breach of such representation or warranty which
results in the termination of this Agreement at the time that it
was made.  For the purposes of the foregoing, "actual knowledge"
in the case of Sellers shall mean the knowledge of any director,
Chief Executive Officer or Chief Financial Officer of Bank or
USB.

     7.03 Amendment.  This Agreement, the Exhibits and the
Schedules hereto may be amended by the parties hereto, by action
taken by or on behalf of the respective Boards of Directors of
Exchange and USB, at any time before or after approval of this
Agreement and the Merger Agreement by the shareholders of USB;
provided, however, that no such modification shall (A) alter the
amount or change the form of the Merger Consideration
contemplated by this Agreement to be received by the shareholders
of USB, (B) adversely affect the tax treatment of the
Shareholders, (C) alter or change any of the terms of this
Agreement if such alteration or change would adversely affect the
shareholders of USB or (D) impede or delay receipt of any
approvals referred to in Section 6.01(b) or the consummation of
the transactions contemplated by this Agreement and the Merger
Agreement.  This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties
hereto.

     7.04 Waiver.  Any term, condition or provision of this
Agreement may be waived in writing at any time by the party which
is, or whose shareholders are, entitled to the benefits thereof.


                          ARTICLE VIII
                        INDEMNIFICATION

     8.01 Indemnification.  The Shareholders, jointly and
severally, and Exchange (individually, the "Indemnifying Party")
agree to defend, indemnify and hold harmless the other party or
parties (the "Indemnitee") and its or their officers, directors,
employees, agents, representatives, successors and assigns from,
against and in respect of any and all loss, liability and expense
resulting from:

          (a)  Any and all loss, diminution in value, damage or
deficiency resulting from any misrepresentation or breach of
warranty or nonfulfillment of any obligation by Indemnifying
Party under this Agreement or from any misrepresentation in or
omission from any certificate or other instrument furnished or to
be furnished by Indemnifying Party pursuant to this Agreement;
and



<PAGE> 



          (b)  Any and all actions, suits, proceedings, claims,
demands, assessments, judgments, costs and expenses (including
legal expenses) incident to any of the foregoing provisions.

     8.02 Claims.  If any Indemnitee receives notice of any claim
or the commencement of any action or proceeding with respect to
which the Indemnifying Party is obligated to provide
indemnification pursuant to Section 8.01, the Indemnitee shall
promptly give the Indemnifying Party notice thereof.  Such notice
shall be a condition precedent to any liability of the
Indemnifying Party under the provisions for indemnification
contained in this Agreement and shall describe the claim in
reasonable detail and shall indicate the amount (estimated if
necessary) of the loss that has been or may be sustained by the
Indemnitee.  The Indemnifying Party may elect to compromise or
defend, at such Indemnifying Party's own expense and by such
Indemnifying Party's own counsel, any such matter involving the
asserted liability of the Indemnitee; provided, however, that to
the satisfaction of the Indemnitee, the Indemnifying Party shall
indemnify and secure the Indemnitee against such contested claims
and for the expenses of contesting and defending the claims.  If
the Indemnifying Party elects to compromise or defend such
asserted liability, it shall within 30 days (or sooner, if the
nature of the asserted liability so requires) notify the
Indemnitee of its intent to do so, and the Indemnitee shall
cooperate, at the expense of the Indemnifying Party, in the
compromise of, or defense against, any such asserted liability. 
If the Indemnifying Party elects not to notify the Indemnitee of
its election as herein provided, the Indemnitee may, if acting in
accordance with its good faith business judgment, pay, compromise
or defend such asserted liability, and such settlement shall be
binding on the Indemnifying Party for purposes of this
Article VIII.  Notwithstanding the foregoing, neither the
Indemnifying Party nor the Indemnitee may settle or compromise
any claim over the objection of the other; provided, however,
that consent to settlement or compromise shall not be
unreasonably withheld.  In any event, the Indemnitee and the
Indemnifying Party may each participate, at its own expense, in
the defense of such asserted liability.  If the Indemnifying
Party chooses to defend any claim, the Indemnitee shall make
available to the Indemnifying Party any books, records or other
documents within its control that are necessary or appropriate
for such defense.

     8.03 Costs.  If any legal action or other proceeding is
brought by any party to this Agreement against any other party to
this Agreement for the enforcement or interpretation of any of
the rights or provisions of this Agreement, or because of an
alleged dispute, breach, default or misrepresentation in
connection with any of the provisions of this Agreement, the
successful or prevailing party shall be entitled to recover
reasonable attorneys' fees and all other costs and expenses
incurred in that action or proceeding, in addition to any other
relief to which it may be entitled.



<PAGE> 



     8.04 Reimbursement.  Subject to the provisions of
Section 8.03, the Indemnitee shall be reimbursed on demand for
loss, damage, cost or expense suffered by such party at any time
after the Closing Date in respect to any liability to which the
foregoing indemnity relates.

     8.05 Net Loss and De Minimis.  Except for any knowing and
intentional breach hereof by any party, no indemnity shall be due
hereunder until such time as the actual net loss or damage (i.e.,
reduced by any recovery from any third party, such as an insurer)
suffered by the Indemnitee exceeds a cumulative aggregate amount
(as to all indemnifiable claims to the date of determination
combined) equal to $25,000.  After cumulative aggregate losses
equal $100,000, Indemnitee shall be entitled to full and complete
recovery of all losses incurred.

     8.06 Limitations.  Notwithstanding any provision of this
Article VIII to the contrary, the extent of indemnification
herein to an Indemnitee by each Indemnifying Party who is also a
Shareholder shall be limited to that portion of the Merger
Consideration that such Shareholder would be entitled to received
under this Agreement.  Notwithstanding any provision of this
Agreement, no Indemnitee shall be entitled to any reimbursement
hereunder from an Indemnifying Party with respect to any claim
initially made against such Indemnifying Party more than one year
after the Closing Date. 


                           ARTICLE IX
                       GENERAL PROVISIONS

     9.01 Non-Survival of Representations, Warranties and
Agreements.  No investigation by the parties hereto made
heretofore or hereafter shall affect the representations and
warranties of the parties which are contained herein and each
such representation and warranty shall survive such
investigation.  Except for and to the extent provided in this
Section 9.01, no representation, warranty, covenant or agreement
contained in this Agreement shall survive the Effective Time or
the earlier termination of this Agreement.  The agreements set
forth in Articles I and VIII and in Sections 5.09, 5.10, 5.11,
5.12, 5.13, 5.14, 5.15, 5.16 and 5.17, and all of the
representations and warranties of Sellers or the Exchange
Entities, shall survive until the first anniversary of the
Closing Date.   The agreements set forth in Section 7.02 shall
survive the Effective Time or the earlier termination of this
Agreement.  

     9.02 No Assignment; Successors and Assigns.  This Agreement
shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns, but neither
this Agreement nor any right or obligation set forth in any
provision hereof may be transferred or assigned by any party
hereto without the prior written consent of all other parties,
and any purported transfer or assignment in violation of this
Section 9.02 shall be void and of no effect.  There shall not be
any third party beneficiaries of any provisions hereof.



<PAGE> 



     9.03 Severability.  Whenever possible, each provision of
this Agreement shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of
this Agreement shall be held to be prohibited by or invalid under
applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating
the remaining provisions of this Agreement.

     9.04 No Implied Waiver.  No failure or delay on the part of
either party hereto to exercise any right, power or privilege
hereunder or under any instrument executed pursuant hereto shall
operate as a waiver nor shall any single or partial exercise of
any right, power or privilege preclude any other or further
exercise thereof or the exercise of any other right, power or
privilege.

     9.05 Headings.  Article, section, subsection and paragraph
titles, captions and headings herein are inserted only as a
matter of convenience and for reference, and in no way define,
limit, extend or describe the scope of this Agreement or the
intent or meaning of any provision hereof.

     9.06 Entire Agreement.  This Agreement and the Appendices
and Schedules hereto constitutes the entire agreement between the
parties with respect to the subject matter hereof, supersedes all
prior negotiations, representations, warranties, commitments,
offers, letters of interest or intent, proposal letters,
contracts, writings or other agreements or understandings with
respect thereto.  No waiver, and no modification or amendment of
any provision of this Agreement shall be effective unless
specifically made in writing and duly signed by all parties
thereto.

     9.07 Counterparts.  This Agreement may be executed in one or
more counterparts, and any party to this Agreement may execute
and deliver this Agreement by executing and delivering any of
such counterparts, each of which when executed and delivered
shall be deemed to be an original and all of which taken together
shall constitute one and the same instrument.

surplus accounts shall equal the combined capital accounts and
surplus accounts, respectively, of USB and of Acquisition Company
immediately prior to the Merger.



<PAGE> 



          Section 3.     At the Effective Time, the members of
the Board of Directors and the terms of these directors shall be
as designated by Exchange immediately prior to the Effective
Time.

          Section 4.     At the Effective Time, the officers of
the Surviving Corporation shall be the persons designated by
Exchange immediately prior to the Effective Time, and such
persons will serve in their designated offices, thereafter, until
their respective successors are duly elected and qualified.

                           ARTICLE III
              Manner and Basis of Converting Shares

          The manner and basis of converting the shares of USB
into the right to receive cash and notes of Exchange and the mode
of carrying the Merger into effect are as follows:

          Section 1.     Conversion of Acquisition Company Common
Stock

          At the Effective Time, the 1,000 shares of Acquisition
Company Common Stock outstanding shall be converted into 100
shares of Surviving Corporation common stock.

          Section 2.     Conversion of USB Common Stock

          (a)  At the Effective Time, Exchange will pay cash and
issue and deliver its promissory notes as provided in the
Acquisition Agreement pursuant to the Merger (hereinafter such
promissory notes and cash shall be referred to in the aggregate
as the "Merger Consideration").  Each of the shareholders of USB
will be entitled to receive the proportion of the Merger
Consideration that is determined by multiplying such Merger
Consideration by such shareholders' respective percentage
ownership interests in USB, adjusted as between cash and notes as
provided in the Acquisition Agreement.

          (b)  At the Effective Time, by virtue of the Merger and
without any action on the part of Exchange, Acquisition Company,
USB or any USB shareholder, each share of USB Common Stock issued
and outstanding at the Effective Time, other than any shares held
by Exchange by virtue of Section 2(a) or any holder who becomes
entitled to payment of the fair value of such shares under
Section 351.455 of the Missouri Revised Statutes, shall cease to
be outstanding and shall be converted into and become the right
to receive his or her share of the Merger Consideration as
determined in Section 2(a) hereof.

          Section 3.     Dissenting USB Shareholders

          The Constituent Corporations agree that the Surviving
Corporation will comply with the provisions of Section 351.455,
as amended, and will promptly pay to the dissenting <PAGE> shareholders
of USB the amount, if any, to which they shall be entitled under
the provisions of said section.

          Section 4.     USB Common Stock Certificates

          After the Effective Time, each holder of an outstanding
certificate which prior thereto represented shares of USB Common
Stock shall be entitled, upon surrender thereof to Exchange or
its designee, to receive in exchange therefor the proportion of
the Merger Consideration into which it is entitled to be
exchanged or converted.  Until so surrendered, each such
outstanding certificate which, prior to the Effective Time,
represented shares of USB Common Stock shall for all purposes
evidence solely the right to receive the Merger Consideration for
which such shares shall be entitled to be exchanged or converted.

          The Merger Consideration shall be paid or issued in
full satisfaction of all rights pertaining to all USB shares
outstanding at the Effective Time.

                            ARTICLE IV
             Other Provisions with Respect to Merger

          Section 1.     This Merger Agreement shall be submitted
to the shareholders of each Constituent Corporation as provided
by Chapter 351 of the Missouri Revised Statutes (the "Missouri
Corporate Law").  After the approval or adoption thereof by the
shareholders of each Constituent Corporation in accordance with
the requirements of the Missouri Corporate Law, and after all
conditions to the consummation of the Merger pursuant to the
Acquisition Agreement have been satisfied or waived by the party
or parties entitled to waive such conditions, all required
documents shall be executed, filed and recorded and all required
acts shall be done in order to accomplish the Merger pursuant to
the Missouri Corporate Law.

          Section 2.     If the Acquisition Agreement is
terminated, then this Merger Agreement shall simultaneously
terminate without further action by the Constituent Corporations. 
In the event of such termination, the Board of Directors of each
of the Constituent Corporations shall direct its officers not to
file this Merger Agreement as provided above notwithstanding
favorable action on this Merger Agreement by the shareholders of
each Constituent Corporation.

                            ARTICLE V
   Approval and Effective Time of Merger; Miscellaneous Matters

          Section 1.  The Merger shall become effective when this
Merger Agreement has been (a) authorized, adopted and approved on
behalf of each Constituent Corporation in accordance with the
Missouri Corporate Law, and (b) filed with the Missouri Secretary
of State.  The time at which such actions are completed and the
required certificate of merger is issued by the Missouri
Secretary of State is herein referred to as the "Effective Time."



<PAGE> 



          Section 2.  If at any time the Surviving Corporation
shall deem or be advised that any further grants, assignments,
confirmations or assurances are necessary or desirable to vest,
perfect or confirm, of record or otherwise, in the Surviving
Corporation the title to any property of USB acquired or to be
acquired by or as a result of the Merger, the officers and
directors of the Surviving Corporation shall be and they hereby
are severally and fully authorized to execute and deliver any and
all such deeds, assignments, confirmations and assurances and to
do all things necessary or proper so as to best prove, confirm
and ratify title to such property in the Surviving Corporation
and otherwise carry out the purposes of the Merger and the terms
of this Merger Agreement.

          Section 3.  For the convenience of the parties, and to
facilitate the filing and recording of this Merger Agreement, any
number of counterparts hereof may be executed, and each such
counterpart shall be deemed to be an original instrument, and all
such counterparts together shall be considered one instrument.

          Section 4.  This Merger Agreement cannot be altered or
amended except pursuant to an instrument in writing signed on
behalf of the parties hereto.
          
          IN WITNESS WHEREOF, each Constituent Corporation has

                        PROMISSORY NOTE

$__________                                   __________, 1997


          FOR VALUE RECEIVED, the undersigned, Exchange National
Bancshares, Inc., a Missouri corporation (the "Maker"), hereby
promises to pay to the order of _______________, his successors,
heirs or assigns (the "Holder") the principal sum of
_________________ Dollars ($__________) on ___________, 2002,
together with interest on the unpaid principal balance hereof at
the rate of seven percent (7%) per annum.  Quarterly installments
of accrued interest only shall be made commencing _________, 1997
and each _________, ________ and ________ thereafter until this
Note is fully paid.  Interest shall be computed for the actual
days elapsed over a year deemed to consist of 365 days.  

          If any installment of this Note becomes due and payable
on a Saturday, Sunday or business holiday in the State of
Missouri, payment shall be made on the next successive business
day with the same effect as though made on the due date. 

          Maker reserves the right to prepay all or any portion
of this Note at any time and from time to time without premium or
penalty of any kind upon 60 days' notice to Holder; provided,
however, that no prepayment of the principal balance of this Note
may be prepaid on or before _______, 2000. 

          If (i) Maker or any other person liable hereon should
make an assignment for the benefit of creditors, (ii) attachment
or garnishment proceedings are commenced against Maker or any
other person liable hereon, (iii) a receiver, trustee or
liquidator is appointed over or execution levied upon any
property of Maker, (iv) proceedings are instituted by or against
Maker or any other person liable hereon under any bankruptcy,
insolvency, reorganization, receivership or other law relating to
the relief of debtors from time to time in effect, including
without limitation the United States Bankruptcy Code, as amended,
(v) Maker liquidates or dissolves, (vi) Maker fails to pay any
principal or interest when due hereunder, (vii) Maker fails to
maintain the collateral described herein, perform or pay any
covenant or obligation in this Note or in any other obligation of
Maker to the Holder hereof in any agreement that secures this
Note or has been executed and delivered to the Holder hereof in
connection with the indebtedness evidenced by this Note,
(viii) Maker breaches any representation or warranty made to
Holder under the Acquisition Agreement (as hereinafter defined),
or (ix) Maker's tangible equity capital at any time is less than
seven percent of its assets, then, and in each such event, Holder
may, at its option, and without notice or demand of any kind
except as provided below, declare the remaining unpaid principal
balance of this Note and all accrued interest thereon immediately
due and payable in full; provided, however, that prior to
declaring a default pursuant to clauses (vi), (vii), (viii) or
(ix), Holder shall give Maker fifteen (15) days' prior notice and
allow an opportunity to cure during such period.  



<PAGE> 



          Any amount hereunder which is not paid when due,
whether at stated maturity, by acceleration or otherwise, shall
bear interest from the date when due until paid at the lesser of
(i) the rate of nine percent (9%) per annum or (ii) the maximum
rate permitted by law, said interest to be compounded annually
and shall be payable to Holder on demand.

          All payments made hereunder shall be made in lawful
currency of the United States of America and paid to Holder at
____________________, or at such other place as Holder may
designate in writing.  All payments made hereunder, whether a
scheduled installment, prepayment or payment as a result of
acceleration, shall be allocated first to accrued but unpaid
interest and then to the principal balance remaining outstanding
hereunder.  

          If default be made, whether by failure to make payment
of any amount when due, or by any other default as defined above,
the Holder of this Note may, at the option of said Holder and
without notice to Maker, declare all unpaid indebtedness
evidenced by this Note or any other obligation of Maker to the
holder hereof immediately due and payable.  Failure to do so at
any time shall not constitute a waiver of the right of the Holder
hereof to do so at any other time.  Upon default, Maker agrees to
pay all costs of collection together with costs of any case or
proceedings under the Bankruptcy laws of the United States.  Such
costs shall include reasonable attorneys' fees incurred in
connection with such collection, whether or not litigation should
be commenced in aid thereof, and such fees incurred in connection
with any such bankruptcy case or proceeding.

          This Note is made pursuant to the provisions of that
certain Acquisition Agreement, dated as of July ___, 1997, among
Maker, ENBUSB Acquisition Company, Union State Bank & Trust of
Clinton (the "Bank"), Union State Bancshares, Inc. ("USB"),
Holder and certain other parties.  This Note is secured by all of
Maker's/USB's interest in and to the common stock of the Bank, as
described in that certain Stock Pledge Agreement, dated as of
_________, 1997, among Maker, Holder and certain other persons
holding similar notes whose obligations are also secured thereby,
and reference to the Stock Pledge Agreement is made for a
statement of the rights of Holder with respect to such
collateral.  The Holder hereof shall also have all of the rights
and may pursue and obtain all of the remedies of a secured party
under the Uniform Commercial Code then effective in the State of
Missouri, and the Holder hereof may immediately dispose of any
part or all of the Collateral held by it as security under such
security documents.

          Maker, for itself and for any guarantors, sureties,
endorsers and/or any other person or persons now or hereafter
liable hereon, if any, hereby waives demand of payment,
presentment for payment, protest, notice of nonpayment or
dishonor and any and all other notices and demands whatsoever,
and any and all delays or lack of diligence in the collection
hereof, and expressly consents and agrees to any and all
extensions or postponements of the time of payment hereof from
time to time at or after maturity and any other indulgence and
waives all notice thereof.



<PAGE> 



          All rights and powers of the Holder hereof shall inure
to its successors or assigns, and all agreements herein shall
bind the successors and assigns of Maker.

          By executing this Note on behalf of Maker, the
undersigned officer of Maker, in his personal and individual
capacity, represents to Holder that such officer is duly
authorized and empowered to execute and deliver this Note on
behalf of Maker and that this Note constitutes the legal, valid
and binding obligation of Maker, enforceable against Maker in
accordance with its terms.

          This Note shall be governed by and construed and
enforced in accordance with the laws of the State of Missouri.

and [list all recipients of Promissory Notes under Acquisition

                             RECITALS

          A.   Pursuant to that certain Acquisition Agreement
dated as of July 11, 1997, as amended, among Exchange National
Bancshares, Inc. ("Borrower"), ENBUSB Acquisition Company, Inc.,
Union State Bancshares, Inc. ("USB"), Union State Bank & Trust of

issued and outstanding capital stock of Subsidiary, as hereafter

<PAGE> 



3.        PLEDGE AND GRANT OF SECURITY INTEREST.

          3.1. To secure the full and prompt payment and
performance of all the obligations of Borrower to each and every
Pledgee under the Notes (the "Secured Obligations"), Pledgor
hereby grants to Pledgee a security interest under the UCC in all
of the Shares.  The Shares are represented by certificates which
are delivered with this Agreement, together with a stock power
attached to each such certificate executed in blank by Pledgor,
to Pledgee or to an escrow agent reasonably satisfactory to each
of Borrower, Pledgor and Pledgee.  The cost of any such escrow
agent shall be borne by Borrower.

          3.2. In addition, Pledgor hereby grants to Pledgee a
security interest in the following (which are deemed to be
included in the term "Shares"): (i) all dividends, cash,
securities, instruments and other property from time to time
paid, payable or otherwise distributed in respect of or in
exchange for any or all of such Shares, (ii) any and all
warrants, options, subscriptions or other contractual
arrangements for the purchase of stock or securities convertible
into stock, (iii) any and all distributions made by Borrower with
respect to the Shares, whether in cash or in kind, by way of
dividends or stock splits, or pursuant to a merger or
consolidation or otherwise, or any substitute security issued
upon conversion, reorganization or otherwise, (iv) any and all
other property hereafter delivered to Pledgor or Pledgee in
substitution for or in addition to any of the foregoing
(including all securities issued pursuant to any shareholder
agreement, stock purchase agreement, stock purchase rights or
other agreement with respect to stock of Borrower to which
Pledgor may now or hereafter be a party), all certificates and
instruments representing or evidencing such property and all
cash, securities, interest, dividends, rights, and other property
at any time and from time to time received, receivable or
otherwise distributed in respect of or in exchange for any or all
thereof, and (v) any and all proceeds of any of the foregoing. 
If any of the foregoing is received by Pledgor, Pledgor will
immediately deliver the same to Pledgee or its designated
nominee, accompanied, if appropriate, by proper instruments of
assignment and/or stock powers executed by Pledgor in accordance
with Pledgee's instructions, to be held subject to the terms of
this Agreement; provided, however, that, if no default then
exists, Pledgor may retain all cash dividends in respect of the
Shares.  If Pledgor fails to make delivery to Pledgor in
compliance with the preceding sentence, all such property shall
be deemed received by Pledgor in trust for the benefit of Pledgee
and shall be segregated from the other property and funds of
Pledgor.

4.        REPRESENTATIONS AND WARRANTIES.  Pledgor represents and
warrants that:

          4.1. Pledgor owns the Shares, free of all security
interests, liens and encumbrances, other than in favor of
Pledgee.

          4.2. There are no outstanding warrants, options,
subscriptions or other contractual arrangements for the purchase
of any other shares of stock or any securities convertible into
shares of stock of Subsidiary.

          4.3. The delivery of the Shares to Pledgee (or escrow
agent) pursuant to this Agreement and the filing of the financing
statement(s), which have been, or contemporaneously with the
execution of this Agreement will be, delivered to Pledgee, in the
offices shown thereon, create a valid and fully perfected first
priority security interest in the Shares, securing the payment of
the Secured Obligations.

          4.4. No consent of any other party (including any
stockholder or creditor of Pledgor) and no governmental approval
is required for the exercise by Pledgee of the voting rights or
other rights <PAGE> or remedies granted in this Agreement with respect
to the Shares (except as may be required in connection with the
disposition of the Shares by laws affecting the offering and sale
of securities generally and by laws regulating the sale of banks
generally and Missouri state trust companies specifically).

          4.5. Pledgor is duly authorized to execute and deliver
this Agreement to Pledgee, and this Agreement constitutes the
legal, valid and binding obligation of Pledgor, enforceable
against Pledgor in accordance with its terms.

          4.6.  Pledgor owns 100% of the issued and outstanding
stock of Subsidiary.

5.        DILUTION OF STOCK.  Pledgor agrees that it will not
cause or permit Subsidiary to issue any stock or other securities
(including any warrants, options, subscriptions or other
contractual arrangements for the purchase of stock or securities
convertible into stock) in addition to or in substitution for the
Shares.  Pledgor will deliver hereunder, immediately upon its
acquisition (directly or indirectly) thereof, any and all
writings evidencing any additional Shares together with executed
stock powers duly endorsed in blank.

6.   ADDITIONAL SECURITY INTERESTS.  Pledgor agrees that it will
not (i) sell or otherwise dispose of, or grant any option with
respect to, any of the Shares, (ii) create or permit to exist any
security interest upon or with respect to any of the Shares,
except for the security interest created by this Agreement, or
(iii) enter into any other contractual obligations which may
restrict or inhibit Pledgee's right or ability to sell or
otherwise dispose of the Shares or any part thereof after the
occurrence of a Default hereunder.

7.   CUSTODY AND PRESERVATION OF THE COLLATERAL.  The powers
conferred on Pledgee hereunder are solely to protect Pledgee's
interest in the Shares and shall not impose any duty on it to
exercise any such powers.  Except for the safe custody of the
Shares in its possession and the accounting for monies actually
received by it hereunder, Pledgee shall have no duty as to the
Shares.  It is expressly agreed that Pledgee shall not have
responsibility for (i) ascertaining or taking action with respect
to calls, conversions, exchanges, maturities, tenders or other
matters relative to the Shares, whether or not Pledgee has or is
deemed to have knowledge of such matters, or (ii) taking any
necessary steps to preserve rights against any third parties with
respect to the Shares.  Pledgee shall be deemed to have exercised
reasonable care in the custody and preservation of any Collateral
in its possession (including the Shares) even if it fails to sell
or convert Collateral which is failing in market value, but
Pledgee may do so at its option and all reasonable expenses
incurred in connection therewith shall be for the sole account of
the Pledgor.  The failure of Pledgee to preserve or protect any
rights with respect to any of the Shares against other parties
will not be deemed a failure to exercise reasonable care in the
custody or preservation of such Shares.

8.        MAINTENANCE OF GOOD STANDING; NO LIQUIDATION OR
DISSOLUTION.  Until Pledgee returns the certificates representing
the Shares to Pledgor and such Shares are released from the
security interest hereof in accordance with Section 15 below,
Pledgor shall cause Subsidiary to maintain in good standing its
corporate existence and its right to transact business in those
states in which it is now or hereafter doing business.  Pledgor
shall not at any time liquidate, merge or dissolve the
Subsidiary, or cause the same to occur, without the prior written
consent of Pledgee.

9.        DEFAULT.  Any one or more of the following constitutes
a "Default" hereunder:



<PAGE> 



          9.1. any representation or warranty made by Pledgor
herein proves to have been untrue or misleading in any material
respect when made;

          9.2. a violation by Pledgor of any of the provisions or
conditions of this Agreement;

          9.3. a change in the stock structure of Subsidiary
which would cause Pledgor, upon liquidation of Subsidiary, to be
entitled to receive less than 100% of the net assets of
Subsidiary; or

          9.4. the occurrence of any default under the Notes, to
the extent not otherwise
described above.

10.       REMEDIES.  Upon the occurrence and during the
continuation of any Default, in addition to all other rights and
remedies of Pledgee under the Notes, at law or in equity, and
subject to applicable law relative to the stock of banks
generally and Missouri trust companies specifically:

          10.1.     Pledgee may at any time exercise any and all
of its rights and pursue any and all of its remedies under the
UCC, under any other applicable Law, and pursuant to this
Agreement and the Notes, including selling some or all of the
Shares at any public sale or, at private sale without
advertisement if in Pledgee's reasonable judgment such private
sale would result in a greater sale price than a public sale.  In
the event Pledgee elects to proceed with respect to some or all
of the Shares, whenever applicable provisions of the UCC require
that notice be reasonable, ten (10) calendar days notice will be
deemed reasonable.  Pledgee will not be obligated to make any
sale of any of the Shares regardless of notice of sale having
been given.  Pledgee may adjourn any public or private sale from
time to time by announcement at the time and place fixed
therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned.  Pledgee may bid
and become a purchaser at any such sale, if public, and upon any
such sale Pledgee may collect, receive, and hold and apply, as
provided herein, the proceeds thereof to the payment of the
Secured Obligations, and assign and deliver some or all of the
Shares and the certificates therefor to the purchaser at any such
sale.  The proceeds from any such sale will be applied first to
the payment of expenses incurred in enforcement and collection of
the Secured Obligations and then to the payment of the Secured
Obligations.

          10.2.     Pledgee may, at any time in its discretion
and without notice to Pledgor, transfer any or all of the Shares
to, or register any or all of the Shares in the name of, Pledgee
or any of its nominees.

          10.3.     In the event that Pledgee determines that it
is advisable to register under or otherwise comply in any way
with the Securities Act of 1933 or any similar federal or state
law, or if such registration or compliance is required with
respect to any or all of the Shares prior to the sale thereof by
Pledgee, Pledgor will use its best efforts to -cause such
registration to be effectively made, at no expense to Pledgee,
and to continue such registration effective for such time as may
be reasonably necessary in the opinion of Pledgee, and will
reimburse Pledgee for any reasonable expense incurred by Pledgee
including reasonable attorneys' and accountants' fees and
expenses in connection therewith; and should Pledgee determine
that, prior to any public offering of any of the Shares, such
securities should be registered under the Securities Act of 1933
and/or registered or qualified under any other federal or state
law, and that such registration and/or qualification is not
practical, then Pledgor agrees that it will cooperate in a
commercially reasonable manner to arrange a private sale so as to
avoid a public offering, even though the sales price established
and/or obtained may be substantially less than might have been
obtained through a public offering.  Pledgor further acknowledges
the impossibility of ascertaining the <PAGE> amount of damages which
would be suffered by Pledgee by reason of the failure by Pledgor
to perform any of the covenants contained in this Section and,
consequently, agrees that, if Pledgor fails to perform any of
such covenants, Pledgor will pay, as damages and not as a
penalty, an amount equal to the value of the Shares on the date
Pledgee demands compliance herewith.

Pledgor hereby appoints Pledgee as Pledgor's attorney-in-fact
effective upon the occurrence of a Default, with full authority
in the place and stead of the Pledgor and in the name of the
Pledgor or otherwise, from time to time in Pledgee's discretion
to take any action and to execute any instrument which Pledgee
may deem necessary or advisable to accomplish the purposes of
this Agreement.

11.       RIGHT TO VOTE SHARES.  Until the Secured Obligations
have been fully and irrevocably paid, Pledgee has the sole right
to vote the Shares with regard to any proposed amendment to the
Articles of Agreement of Subsidiary which would result in a
change in the preferences, qualifications, limitations,
restrictions, or the special or relative rights with respect to
the Shares.  Otherwise, Pledgor has the sole right to vote the
Shares unless there is a Default hereunder.  Upon the occurrence
of a Default, all rights of the Pledgor to exercise the voting
and other consensual rights which it would otherwise be entitled
to exercise pursuant hereto shall cease, and all such rights
shall, upon notice by Pledgee to Pledgor, become vested in
Pledgee who thereupon shall have the sole right to exercise such
voting and other consensual rights and the sole right to receive
and hold as Collateral any dividends (and to the extent
permissible, apply them to the Secured Obligations).

12.       PRESERVATION AND PERFECTION OF SECURITY INTERESTS. 
Pledgor will promptly, upon the request of Pledgee and at
Pledgor's expense, execute, acknowledge and deliver, or cause the
execution, acknowledgment and delivery of, and thereafter, if
applicable, register, file or record in an appropriate
governmental office, any document or instrument supplemental to
or confirmatory of this Agreement, and give such further
assurances as may otherwise be necessary or desirable for the
creation, preservation and/or perfection of the security
interests described in this Agreement.

13.       RELEASES.  In the event all of the Secured Obligations
have been fully and irrevocably paid, and Pledgee has received a
written request from Pledgor in connection therewith, Pledgee
will, at Pledgor's sole cost and expense, return to Pledgor all
certificates representing the Shares that have not been sold,
disposed of, retained, or applied to the Secured Obligations,
with the stock powers executed by Pledgor attached, and such
Shares will be deemed released from any security interest
hereunder.  Notwithstanding the foregoing, if Pledgor or Borrower
shall deliver to Pledgee, at Borrower's cost, an irrevocable
standby letter of credit in form and substance acceptable to
Pledgee, which fully secures the amounts outstanding under the
Notes, then Pledgee will, at Pledgor's sole cost and expense,
return to Pledgor all certificates representing the Shares that
have not been sold, disposed of, retained, or applied to the
Secured Obligations, with the stock powers executed by Pledgor
attached, and such Shares will be deemed released from any
security interest hereunder.

14.       SURVIVAL OF PROVISIONS.  All representations,
warranties, and covenants of Pledgor contained herein survive the
execution and delivery of this Agreement, and terminate only upon
the full and irrevocable payment of all of the Secured
Obligations.

pages hereof or when deposited in the United States mail, postage
prepaid, or, in the case of telegraphic notice, or the overnight
courier services, when delivered to the telegraph company or
overnight courier service, or in the case of telex or telecopy
notice, when sent, verification received, in each case addressed
as set forth on the signature pages hereof, or to such other
address as either party may designate by notice to the other in
accordance with the terms of this Section.  No notice given to or
demand made on Pledgor by Pledgee in any instance entities
Pledgor to notice or demand in any other instance.

          15.2.     AMENDMENTS AND WAIVERS.  No amendment to,
waiver of, or departure from full compliance with any provision
of this Agreement, or consent to any departure by Pledgor
herefrom, will be effective unless it is in writing and signed by
authorized officers of Pledgor and Pledgee; provided, however,
that any such waiver or consent will be effective only in the
specific instance and for the purpose for which given.  No
failure by Pledgee to exercise, and no delay by Pledgee in
exercising, any right, remedy, power or privilege hereunder will
operate as a waiver thereof, nor will any single or partial
exercise by Pledgee of any right, remedy, power or privilege
hereunder preclude any other exercise thereof, or the exercise of
any other right, remedy, power or privilege.

          15.3.     RIGHTS CUMULATIVE.  Each of the rights and
remedies of Pledgee under this Agreement is in addition to all of
their other rights and remedies under applicable law, and nothing
in this Agreement may be construed as limiting any such rights or
remedies.

          15.4.     SUCCESSORS AND ASSIGNS.  This Agreement binds
Pledgor and its successors and assigns and inures to the benefit
of Pledgee, and each of their successors, transferees,
participants and assignees.  Pledgor may not delegate or transfer
any of its obligations under this Agreement without the prior
written consent of Pledgee, except that in the event that
Borrower elects to dissolve Pledgor, Borrower or the then holder
of the Shares shall assume, in a writing delivered to Pledgee,
all of the obligations of Pledgor hereunder.  With respect to
Pledgor's successors and assigns, such successors and assigns
include any receiver, trustee or debtor-in-possession of or for
Pledgor.

          15.5.     SEVERABILITY.  Any provision of this
Agreement which is prohibited, unenforceable or not authorized in
any jurisdiction is, as to such jurisdiction, ineffective to the
extent of such prohibition, unenforceability or nonauthorization
without invalidating the remaining provisions hereof or affecting
the validity, enforceability or legality of such provision in any
other jurisdiction unless the ineffectiveness of such provision
would result in such a material change as to cause completion of
the transactions contemplated hereby to be unreasonable.

          15.6.     GOVERNING LAW; NO THIRD PARTY RIGHTS.  This
Agreement is to be governed by and construed and interpreted in
accordance with the internal Laws of the State of Missouri
applicable to contracts made and to be performed wholly within
such state, without regard to choice or conflicts of law
principles.  This Agreement is solely for the benefit of the
parties hereto and their respective successors and assigns, and
no other Person has any right, benefit, priority or interest
under, or because of the existence of, this Agreement.



<PAGE> 



          15.7.     COUNTERPARTS.  This Agreement may be executed
by the parties hereto on any number of separate counterparts, and
all such counterparts taken together constitute one and the same
instrument.  It is not necessary in making proof of this
Agreement to produce or account for more than one counterpart
signed by the party to be charged.

          15.8.     COUNTERPART FACSIMILE EXECUTION.  For
purposes of this Agreement, a document (or signature page
thereto) signed and transmitted by facsimile machine or
telecopier is to be treated as an original document.  The
signature of any Person thereon, for purposes hereof, is to be
considered as an original signature, and the document transmitted
is to be considered to have the same binding effect as an
original signature on an original document.  At the request of
any party hereto, any facsimile or telecopy document is to be
re-executed in original form by the Persons who executed the
facsimile or telecopy document.  No party hereto may raise the
use of a facsimile machine or telecopier or the fact that any
signature was transmitted through the use of a facsimile or
telecopier machine as a defense to the enforcement of this
Agreement or any amendment or other document executed in
compliance with this Section.

          15.9.     FINAL EXPRESSION; NO COURSE OF DEALING.  This
Agreement, together with the Notes and any other agreement
executed in connection herewith or therewith, is intended by the
parties as a final expression of their agreement and is intended
as a complete and exclusive statement of the terms and conditions
thereof.  Acceptance of or acquiescence in a course of
performance or course of dealing rendered or taken under or with
respect to this Agreement or the Notes will not be relevant to
determine the meaning of this Agreement or the Notes even though
the accepting or acquiescing party had knowledge of the nature of
the performance and opportunity for objection.

          15.10.    NEGOTIATED TRANSACTION.  Pledgor and Pledgee
each represent to the other that in the negotiation and drafting
of this Agreement each has been represented by and has relied
upon the advice of counsel of its choice.  Each of Pledgor and
Pledgee affirm that its counsel has had a substantial role in the
drafting and negotiation of this Agreement; therefore, this
Agreement will be deemed drafted by each of Pledgor and Pledgee,
and the rule of construction to the effect that any ambiguities
are to be resolved against the drafter will not be employed in
the interpretation of this Agreement.

          15.11.    ATTORNEY'S FEES AND OTHER COSTS.  Pledgor
will reimburse Pledgee for all expenses incurred by Pledgee in
seeking to collect or enforce the Secured Obligations and any
other rights under this Agreement or any of the other instrument,
document or agreement evidencing or executed in connection with
any of the Secured Obligations, including reasonable attorneys'
fees and actual attorneys' expenses (whether or not there is
litigation), court costs and all costs in connection with any
proceedings under the United States Bankruptcy Code, and any
expenses incurred on account of damage to any property to which
any of the Collateral may be affixed.

          15.12.    ASSIGNMENT BY PLEDGEE.  Pledgee may assign or
transfer to another Person any instrument, document or agreement
evidencing any of the Secured Obligations and Pledgee's rights
under this Agreement, and may deliver all the property which is
part of the Collateral and in its possession to the participant,
assignee or transferee or to any Person acting as agent for
Pledgee.

          15.13.    REINSTATEMENT.  This Agreement and any and
all security interests created or evidenced hereby will continue
to be effective or be reinstated, as the case may be, as though
such payments had not been made, if at any time any amount
received by Pledgee in respect of the Secured Obligations is
rescinded or must otherwise be restored or returned by Pledgee,
including upon the <PAGE> insolvency, bankruptcy, dissolution,
liquidation or reorganization of Pledgor or upon the appointment
of any intervenor or conservator of, or trustee or similar
official for, Pledgor, any substantial part of its assets, or
otherwise.

          IN WITNESS WHEREOF, this Agreement has been duly
executed as of the date first above written.

period commencing on the date hereof and terminating on the date
six (6) years thereafter. 

          5.  Compensation.

     Company shall pay to Consultant the aggregate sum of
     three hundred thousand dollars ($300,000), without

<PAGE> 



          (b) In the event of the death of Consultant during

          6.  Judicial Modification.  Although the parties hereto
consider the restrictions contained in Section 3 of this
Agreement to be reasonable for the purposes set forth herein, if
a final judicial determination is made by a court of competent
jurisdiction that the time, territory, scope or other restriction
contained in Section 3 of this Agreement is an unreasonable or
otherwise unenforceable restriction against Consultant, neither
this Agreement nor the provisions of such Section shall be
rendered void, but shall be deemed amended to apply as to such
maximum time, territory, scope and to such other extent as such
court may judicially determine or indicate to be reasonable or,
if such court does not so determine or indicate, to the maximum
extent which any pertinent statute or judicial decision may
indicate to be a reasonable restriction under the circumstances
involved.

          7.  Remedies.  Consultant acknowledges and agrees that
the Company's remedy at law for a breach or threatened breach of
any of the provisions of Section 3 of this Agreement would be
inadequate and, in recognition of that fact, in the event of any
such breach or threatened breach, it is agreed that, in addition
to its remedy at law, the Company shall be entitled to, and
Consultant agrees not to oppose the Company's request for,
equitable relief in the form of specific performance, temporary
restraining order, temporary or permanent injunction or any other
equitable remedy which may then be available.  Nothing herein
contained shall be construed as prohibiting the Company from
pursuing any other remedies available to it for such breach or
threatened breach. 

          8.  Independent Contractor.  During the term of this
Agreement, Consultant shall act in the capacity of an independent
contractor and shall not be subject to the direction, control or
supervision of the Company with respect to the method or
performance of the consulting services hereunder.  Consultant
shall be solely responsible for the payment of any income or
payroll taxes applicable to the payments made under Section 4
hereof.



<PAGE> 


          9.  Miscellaneous.  

          (a)  This Agreement cancels and supersedes all
     previous agreements relating to the subject matter of
     this Agreement, written or oral, between the parties
     hereto and contains the entire understanding of the

     or supplemented in any manner whatsoever except as
     otherwise provided herein or in writing signed by each

          (b)  The waiver by either party, or the failure by
     either party to claim a breach (or give notice with

     subsequent breach, or deemed to affect in any way the
     effectiveness, of such provision.

     rights, duties or obligations of either party

     without the prior written consent of the other party
     hereto.  This Agreement shall be binding upon, and
     inure to the benefit of and be enforceable by, the
     parties hereto and their respective successors and
     permitted assigns.

          (d)  In the event a final judicial determination
     is made by a court of competent jurisdiction that any
     provision of this Agreement is illegal, invalid or
     unenforceable to any extent, the legality, validity and
     enforceability of the other provisions of this 
     Agreement shall not be affected thereby, said provision
     shall be modified by the court to the extent necessary
     to render it not illegal, invalid or unenforceable, and
     this Agreement shall continue in full force and effect
     as modified and shall be enforced to the fullest extent
     permitted by law.

          (e)  This Agreement may be executed in any number
     of counterparts, each of which shall be deemed to be an

     for the remainder of the term, but shall make such
     payments to Smith's estate or such other beneficiary as
     shall be designated by Smith from time to time in
     writing.

          3.  Judicial Modification.  Although the parties hereto
consider the restrictions contained in Section 1 of this
Agreement to be reasonable for the purposes set forth herein, if
a final judicial determination is made by a court of competent
jurisdiction that the time, territory, scope or other restriction
contained in Section 1 of this Agreement is an unreasonable or
otherwise unenforceable restriction against Smith, neither this
Agreement nor the provisions of such Section shall be rendered
void, but shall be deemed amended to apply as to such maximum
time, territory, scope and to such other extent as such court may
judicially determine or indicate to be reasonable or, if such
court does not so determine or indicate, to the maximum extent
which any pertinent statute or judicial decision may indicate to
be a reasonable restriction under the circumstances involved.

          4.  Remedies.  Smith acknowledges and agrees that the
Company's remedy at law for a breach or threatened breach of any
of the provisions of Section 1 of this Agreement would be
inadequate and, in recognition of that fact, in the event of any
such breach or threatened breach, it is agreed that, in addition
to its remedy at law, the Company shall be entitled to, and Smith
agrees not to oppose the Company's request for, equitable relief
in the form of specific performance, temporary restraining order,
temporary or permanent injunction or any other equitable remedy
which may then be available.  Nothing herein contained shall be
construed as prohibiting the Company from pursuing any other
remedies available to it for such breach or threatened breach. 

          5.  Miscellaneous.  

          (a)  This Agreement cancels and supersedes all
     previous agreements relating to the subject matter of
     this Agreement, written or oral, between the <PAGE> parties
     hereto and contains the entire understanding of the
     parties hereto with respect to the subject matter
     hereof.  This Agreement shall not be amended, modified 
     or supplemented in any manner whatsoever except as
     otherwise provided herein or in writing signed by each
     of the parties hereto.

          (b)  The waiver by either party, or the failure by
     either party to claim a breach (or give notice with
     respect thereto), of any provision of this Agreement
     shall not be, or be deemed to be, a waiver of any
     subsequent breach, or deemed to affect in any way the
     effectiveness, of such provision.

          (c)  Neither this Agreement, nor any of the
     rights, duties or obligations of either party
     hereunder, may be assigned (either voluntarily or by
     operation of law) or otherwise delegated by such party
     without the prior written consent of the other party
     hereto.  This Agreement shall be binding upon, and
     inure to the benefit of and be enforceable by, the
     parties hereto and their respective successors and
     permitted assigns.

          (d)  In the event a final judicial determination
     is made by a court of competent jurisdiction that any
     provision of this Agreement is illegal, invalid or
     unenforceable to any extent, the legality, validity and
     enforceability of the other provisions of this 
     Agreement shall not be affected thereby, said provision
     shall be modified by the court to the extent necessary
     to render it not illegal, invalid or unenforceable, and
     this Agreement shall continue in full force and effect
     as modified and shall be enforced to the fullest extent
     permitted by law.

          (e)  This Agreement may be executed in any number
     of counterparts, each of which shall be deemed to be an
     original and all of which together shall constitute one
     agreement which is binding upon all the parties hereto.

                       EMPLOYMENT AGREEMENT


          THIS AGREEMENT (this "Agreement") is entered into this
____ day of __________, 1997, between Exchange National
Bancshares, Inc., a Missouri corporation (the "Company"), and
James E. Smith (the "Employee").

                          WITNESSETH:

          WHEREAS, the Company is a bank holding company
controlling 100% of the issued and outstanding shares of common
stock of Union State Bank & Trust of Clinton, a Missouri trust
company (the "Bank"); and

          WHEREAS, Employee desires to become employed by the
Company in an executive capacity as President of the Bank for a
period of at least three years, and the Company desires to employ
Employee to serve in such capacity, for the compensation and in
accordance with the terms and provisions contained herein; and

          NOW, THEREFORE, in consideration of the foregoing and
the mutual promises and covenants contained herein, the Company
and Employee agree as follows:

          1.  Employment.  The Company agrees to employ the
Employee and the Employee agrees to be employed by the Company in
an executive capacity upon the terms and conditions of this
Agreement for a period of three (3) years from and after the date
of this Agreement, and any extensions thereafter, unless earlier
terminated as provided in Section 9 hereof.   At each anniversary
of the date of this Agreement prior to the sixty-second (62nd)
birthday of the Employee, this Agreement shall be automatically
extended for one additional year unless the Company  or the
Employee gives the other party written notice of such party's
intention not to extend this Agreement at least thirty (30) days
prior to such anniversary date.   Employee agrees that his
employment by the Bank shall satisfy the Company's employment
obligation hereunder and that he will accept employment as
President of the Bank, so long, during the term of this
Agreement, that the Bank's Board of Directors shall name him to
be elected to that position.  The Employee's primary location of
employment during the term of this Agreement shall be in Clinton,
Missouri unless the Employee consents in writing to relocate to
another geographic location. 

          2.  Compensation.  For all services rendered by the
Employee to the Bank and the Company, the Bank and the Company
shall pay the Employee a salary of not less than one hundred and
ten thousand dollars ($110,000) per year, payable in accordance
with the customary payroll practices of the Bank and the Company,
but in no event less frequently than monthly.  Salary payments
shall be subject to withholding and other applicable taxes. 
Employee shall be eligible for merit-based increases in
compensation on terms and conditions offered to employees of the
Company generally having responsibilities commensurate to that of
Employee.  Employee shall be eligible to <PAGE> participate in such
bonus or other incentive compensation plans as currently are or
may hereafter be established by the Company for employees
generally having responsibilities commensurate to that of
Employee, and which may relate to his contribution to the
profitability of the Bank.  Employee shall receive board of
directors fees for his service to the Bank's board, which in any
event shall not be less than three hundred dollars ($300.00) for
each board of directors' meeting attended.  Employee shall
receive the same board of directors fees for service on the
Company's board of directors or any other affiliated board as is
customarily paid to employees of the Bank and the Company serving
in such capacity.

          3.  Expenses. The Company shall reimburse the Employee
for all ordinary and necessary expenses incurred and paid by the
Employee in the course of the performance of the Employee's
duties pursuant to this Agreement and consistent with the
Company's policies in effect from time to time with respect to
travel, entertainment and other business expenses, and subject to
the Company's requirements with respect to the manner of
reporting such expenses.   

          4.  Additional Benefits.  The Employee shall be
eligible for such fringe benefits, if any, by way of insurance,
hospitalization and vacations normally provided to employees of
the Company generally having responsibility commensurate to that
of the Employee and such additional benefits as may be from time
to time agreed upon in writing between the Employee and the
Company.  The Company shall provide to the Employee a new Company
owned or leased automobile of a year, make and model selected by
the Company befitting the executive office held by Employee with
Bank not less than every three years, and the Company shall pay
the expenses related to the use and upkeep thereof and insurance
related thereto.  The tax treatment of all fringe benefits shall
be handled in a manner consistent with the customary practices of
the Bank and the Company.  

          5.  Duties.  The Employee agrees that so long as he is
employed under this Agreement he will (i) to the satisfaction of
the Company devote his best efforts and his entire business time
to further properly the interests of the Company, which shall
include all of Employee's current activities and participation in
the American Banker's Association, Missouri Banker's Association,
CSBS and other similar industry groups and organizations (and
such other additional activities and participation in such other
organizations as may be approved by the board of directors of the
Company), and the Company and the Bank acknowledge that such
listed activities shall, together with Employee's duties to the
Bank, constitute Employee's entire business time to further the
interests of the Company and the Bank, (ii) at all times be
subject to the direction and control of the Board of Directors of
his employer (which may be the Company or the Bank, as provided
in Section 1 hereof) with respect to his activities on behalf of
such employer, (iii) comply with all rules, orders and
regulations of the Company, (iv) truthfully and accurately
maintain and preserve such records and make all reports as the
Company may require, and (v) fully account for all monies and
other property of the Company of which he may from time to time
have custody and deliver the same to the Company whenever and
however directed to do so.

          6.  Covenant Not to Disclose Confidential Information. 
The Employee acknowledges that during the course of his
employment with the Company he has or will have access to and


<PAGE> 



knowledge of certain information and data which the Company
considers confidential and that the release of such information
or data to unauthorized persons would be extremely detrimental to
the Company.  As a consequence, the Employee hereby agrees and
acknowledges that he owes a duty to the Company not to disclose,
and agrees that, during or after the term of his employment,
without the prior written consent of the Company he will not
communicate, publish or disclose, to any person anywhere or use
any Confidential Information (as hereinafter defined) for any
purpose other than carrying out his duties as contemplated by
this Agreement.  The Employee will use his best efforts at all
times to hold in confidence and to safeguard any Confidential
Information from falling into the hands of any unauthorized
person and, in particular, will not permit any Confidential
Information to be read, duplicated or copied.  The Employee will
return to the Company all Confidential Information in the
Employee's possession or under the Employee's control when the
duties of the Employee no longer require the Employee's
possession thereof, or whenever the Company shall so request, and 
in any event will promptly return all such Confidential
Information if the Employee's relationship with the Company is
terminated for any or no reason and will not retain any copies
thereof.  For purposes hereof the term "Confidential Information"
shall mean any information or data used by or belonging or
relating to the Company that is not known generally to the
banking community, including without limitation, any and all
proprietary data and information relating to the Company's or the
Bank's past, present or future business plans, services offered,
financial information, customer lists, and other information
concerning customers, depositors and borrowers of the Company or
any subsidiary of the Company, whether or not reduced to writing,
or information or data which the Company advises the Employee
should be treated as confidential information.   

          7.  Covenant Not to Compete.  The Employee agrees that
during the term of his employment by the Company and for a period
of two (2) years from and after the voluntary or involuntary
termination of such employment for any reason other than a
termination by the Employee pursuant to Section 9(c), he will
not, directly or indirectly, without the express written consent
of the Company: 

          (a)  own, manage, operate, control or participate
     in the ownership, management, operation , control or
     financing of, or have any interest, financial or
     otherwise, in or act as an officer, director, partner,
     principal, employee, agent, representative, consultant
     or independent contractor of, or in any way assist any
     bank, savings and loan, savings bank or other financial
     institution (other than the Bank) that is located or
     has an office in or within fifteen (15) miles from any
     boundary of Henry or St. Clair County, Missouri; 

          (b) solicit for employment or hire any employees
     of the Bank; or

          (c) solicit, or interfere with, any contracts or
     business relationships with any customer, depositor or
     borrower of the Bank.

          8.  Remedies.  Recognizing that irreparable damage will
result to the Company in the event of the breach or threatened
breach of any of the foregoing covenants and assurances by the


<PAGE> 



Employee contained in Sections 6 or 7 hereof, and that the
Company's remedies at law for any such breach or threatened
breach will be inadequate, the Company and its successors and
assigns, in addition to such other remedies which may be
available to them, shall be entitled to an injunction, including
a mandatory injunction, to be issued by any court of competent
jurisdiction ordering compliance with this Agreement or enjoining
and restraining the Employee, and each and every person, firm or
company acting in concert or participation with him, from the
continuation of such breach and, in addition thereto, he shall
pay to the Company all ascertainable damages, including costs and
reasonable attorneys' fees sustained by the Company by reason of
the breach or threatened breach of said covenants and assurances. 
The obligations of the Employee and the rights of the Company,
its successors and assigns under Sections 6 and 7 of this
Agreement shall survive the termination of this Agreement.  The
covenants and obligations of the Employee set forth in Sections 6
and 7 hereof are in addition to and not in lieu of or exclusive
of any other obligations and duties of the Employee to the
Company, whether express or implied in fact or in law.

          9.  Termination.

          (a)  This Agreement shall terminate immediately
     upon the death, disability or adjudication of legal
     incompetence of the Employee.  For purposes of this
     Agreement, the Employee shall be deemed to be disabled
     when the employee has become unable, by reason of
     physical or mental disability, to satisfactorily
     perform his essential job duties and there is no
     reasonable accommodation that can be provided to enable
     him to be a qualified individual with a disability
     under applicable law.  Such matters shall be determined
     by, or to the reasonable satisfaction of, the Board of
     Directors of the Company.

          (b)  This Agreement may be terminated by the
     Company upon notice to the Employee for "Cause." For
     purposes of this Agreement, "Cause" shall mean the
     occurrence of any of the following events:

               (i)  Performance by the Employee of
          illegal or fraudulent acts, criminal conduct
          or willful misconduct or gross negligence
          relating to the activities of the Company or
          the Bank;

               (ii) Performance by the Employee of any
          criminal acts involving moral turpitude
          having a material adverse effect upon the
          Company or the Bank, including, without
          limitation, upon their profitability,
          reputation or goodwill;

               (iii)  Failure by the Employee to
          perform his duties in a manner which he
          knows, or has reason to know, to be in the
          Company's or the Bank's best interests, which
          he fails to cure promptly after receiving
          written notice thereof;



<PAGE> 



               (iv)  Continued conduct by the Employee
          that is damaging to the business, employee or
          customer relations of the Company or the Bank
          after receiving written notice from the
          Company or the Bank to cease such conduct; or

               (v)  Any other material breach of the
          Employee's obligations hereunder which is
          incurable or which he fails to cure promptly
          after receiving written notice thereof.

          (c)    This Agreement may be terminated by the
     Employee upon written notice to the Company in the
     event of a material breach of the Company's obligations
     hereunder which is incurable or which the Company fails
     to cure within 15 days after receiving written notice
     thereof.

          (d)  In the event this Agreement is terminated,
     the parties' obligations under this Agreement shall
     terminate immediately (except as otherwise provided
     herein), and neither the Employee nor his estate,
     heirs, successors or assigns shall be entitled to any
     further compensation hereunder other than payment of
     any unpaid compensation  that accrued prior to such
     termination; provided, however, that the termination of
     this Agreement pursuant to subsections (b) or (c) of
     this Section shall not limit any other remedies to
     which the terminating party may be entitled in law or
     in equity as a result of any breach of this Agreement
     by the other party hereto.  

          10.  Waiver of Breach.  Failure of the Company to
demand strict compliance with any of the terms, covenants or
conditions hereof shall not be deemed a waiver of the term,
covenant or condition, nor shall any waiver or relinquishment by
the Company of any right or power hereunder at any one time or
more times be deemed a waiver or relinquishment of the right or
power at any other time or times.

          11.  No Conflicts.  The Employee represents and
warrants to the Company that neither the execution nor delivery
of this Agreement, nor the performance of the Employee's
obligations hereunder will conflict with, or result in a breach
of, any term, condition, or provision of, or constitute a default
under, any obligation, contract, agreement, covenant or
instrument to which the Employee is a party or under which the 
Employee is bound, including without limitation, the breach by
the Employee of a fiduciary duty to any former employers.

          12.  Entire Agreement; Amendment.  This Agreement
cancels and supersedes all previous agreements relating to the
subject matter of this Agreement, written or oral, between the
parties hereto and contains the entire understanding of the
parties hereto relating to the terms of the Employee's employment
and shall not be amended, modified or supplemented in any manner
whatsoever except as otherwise provided herein or in writing
signed by each of the parties hereto.



<PAGE> 



          13.  Headings.  The headings of the sections of this
Agreement have been inserted for convenience of reference only
and shall in no way restrict or otherwise modify any of the terms
or provisions hereof.

          14.  Governing Law.  This Agreement and all rights and
obligations of the parties hereunder shall be governed by, and
construed and interpreted in accordance with, the laws of the
State of Missouri applicable to agreements made and to be
performed entirely within the State, including all matters of
enforcement, validity and performance.

          15.  Arbitration.  Any dispute between any of the
parties hereto or claim by a party against another party arising
out of or in relation to this Agreement or in relation to any
alleged breach thereof shall be finally determined by arbitration
in accordance with the rules then in force of the American
Arbitration Association.  The arbitration proceedings shall take
place in Jefferson City, Missouri or such other location as the
parties in dispute hereafter may agree upon; and such proceedings
shall be governed by the laws of the State of Missouri as such
laws are applied to agreements between residents of such State
entered into and to be performed entirely within that State.  

          The parties shall agree upon one arbitrator, who shall
be an individual skilled in the legal and business aspects of the
subject matter of this Agreement and of the dispute.  If the
parties cannot agree upon one arbitrator, each party in dispute
shall select one arbitrator and the arbitrators so selected shall
select a third arbitrator.  In the event the arbitrators cannot
agree upon the selection of a third arbitrator, the third
arbitrator shall be appointed by the American Arbitration
Association at the request of any of the parties in dispute.  The
arbitrators shall, if possible, be individuals skilled in the
legal and business aspects of the subject matter of this
Agreement and of the dispute.

          The decision rendered by the arbitrator or arbitrators
shall be accompanied by a written opinion in support thereof. 
The decision shall be final and binding upon the parties in
dispute without right of appeal.  Judgment upon the decision may
be entered into in any court having jurisdiction thereof, or
application may be made to that court for a judicial acceptance
of the decision and an order of enforcement.  Costs of the
arbitration shall be assessed by the arbitrator or arbitrators
against any or all of the parties in dispute, and shall be paid
promptly by the party or parties so assessed.

          16.  Counterparts.  This Agreement may be executed in
any number of counterparts, each of which shall be deemed to be
an original and all of which together shall constitute one
agreement which is binding upon all the parties hereto.

superior supervisor with respect to his activities on behalf of
such employer, (iii) comply with all rules, orders and

          6.  Covenant Not to Disclose Confidential Information. 
The Employee acknowledges that during the course of his
employment with the Company he has or will have access to and
knowledge of certain information and data which the Company
considers confidential and that the release of such information
or data to unauthorized persons would be extremely detrimental to
the Company.  As a consequence, the Employee hereby agrees and
acknowledges that he owes a duty to the Company not to disclose,
and agrees that, during or after the term of his employment,
without the prior written consent of the Company he will not
communicate, publish or disclose, to any person anywhere or use
any Confidential Information (as hereinafter defined) for any
purpose other than carrying out his duties as contemplated by
this Agreement.  The Employee will use his best efforts at all
times to hold in confidence and to safeguard any Confidential
Information from falling into the hands of any unauthorized
person and, in particular, will not permit any Confidential
Information to be read, duplicated or copied.  The Employee will
return to the Company all Confidential Information in the
Employee's possession or under the Employee's control when the
duties of the Employee no longer require the Employee's
possession thereof, or whenever the Company shall so request, and 
in any event will promptly return all such Confidential
Information if the Employee's relationship with the Company is
terminated for any or no reason and will not retain any copies
thereof.  For purposes <PAGE> hereof the term "Confidential Information"
shall mean any information or data used by or belonging or
relating to the Company that is not known generally to the
banking community, including without limitation, any and all
proprietary data and information relating to the Company's or the
Bank's past, present or future business plans, services offered,

any subsidiary of the Company, whether or not reduced to writing,
or information or data which the Company advises the Employee
should be treated as confidential information.   

          7.  Covenant Not to Compete.  The Employee agrees that
during the term of his employment by the Company (whether or not
this agreement has expired or been terminated) and for a period
of two (2) years from and after the voluntary or involuntary
termination of such employment for any reason other than a
termination by the Employee pursuant to Section 9(c), he will
not, directly or indirectly, without the express written consent
of the Company: 

          (a)  own, manage, operate, control or participate
     in the ownership, management, operation , control or
     financing of, or have any interest, financial or
     otherwise, in or act as an officer, director, partner,
     principal, employee, agent, representative, consultant
     or independent contractor of, or in any way assist any
     bank, savings and loan, savings bank or other financial
     institution (other than the Bank) that is located or
     has an office in or within fifteen (15) miles from any
     boundary of Henry or St. Clair County, Missouri; 

          (b) solicit for employment or hire any employees

          8.  Remedies.  Recognizing that irreparable damage will
result to the Company in the event of the breach or threatened
breach of any of the foregoing covenants and assurances by the
Employee contained in Sections 6 or 7 hereof, and that the
Company's remedies at law for any such breach or threatened
breach will be inadequate, the Company and its successors and
assigns, in addition to such other remedies which may be
available to them, shall be entitled to an injunction, including
a mandatory injunction, to be issued by any court of competent
jurisdiction ordering compliance with this Agreement or enjoining
and restraining the Employee, and each and every person, firm or
company acting in concert or participation with him, from the
continuation of such breach and, in addition thereto, he shall
pay to the Company all ascertainable damages, including costs and
reasonable attorneys' fees sustained by the Company by reason of
the breach or threatened breach of said covenants and assurances. 
The obligations of the Employee and the rights of the Company,
its successors and assigns under Sections 6 and 7 of this
Agreement shall survive the termination of this Agreement.  The
covenants and obligations of the Employee set forth in Sections 6
and 7 hereof are in addition to and not in lieu of or exclusive
of any other obligations and duties of the Employee to the
Company, whether express or implied in fact or in law.

               (v)  Any other material breach of the
          Employee's obligations hereunder which is

     heirs, successors or assigns shall be entitled to any
     further compensation hereunder other than payment of
     any unpaid compensation  that accrued prior to such
     termination; provided, however, that the termination of
     this Agreement pursuant to subsections (b) or (c) of
     this Section shall not limit any other remedies to
     which the terminating party may be entitled in law or
     in equity as a result of any breach of this Agreement
     by the other party hereto.

          10.  Termination Following Expiration of Term.  In the

Company shall pay Employee six months' severance pay at a rate
equal to his salary at the time of such termination, payable on a

monthly severance payments to Employee so long as Employee
continues to comply with his obligations under Section 6 and 7
hereof.

demand strict compliance with any of the terms, covenants or
conditions hereof shall not be deemed a waiver of the term,

warrants to the Company that neither the execution nor delivery
of this Agreement, nor the performance of the Employee's

the Employee of a fiduciary duty to any former employers.
