EMPLOYEES

309 full-time and 68 part-time employees. None of its employees is presently
represented by any union or collective bargaining group, and our Company
considers its employee relations to be satisfactory.

COMPETITION

     Bank holding companies and their subsidiaries and affiliates encounter
intense competition from nonbanking as well as banking sources in all of their
activities. Our Banks' competitors include other commercial banks, thrifts,
savings banks, credit unions and money market mutual funds. Thrifts and credit
unions now have the authority to offer checking accounts and to make corporate
and agricultural loans and were granted expanded investment authority by recent
federal regulations. In addition, large national and multinational corporations
have in recent years become increasingly visible in offering a broad range of
financial services to all types of commercial and consumer customers. In our
Banks' respective service areas, new competitors, as well as the expanding
operations of existing competitors, have had, and are expected to continue to
have, an adverse impact on our Banks' market share of deposits and loans in such
service areas.

     Exchange National Bank experiences substantial competition for deposits and
loans within both its primary service area of Jefferson City and its secondary
service area of the nearby communities in Cole, Moniteau, and Pulaski Counties.
Exchange National Bank's principal competition for deposits and loans comes from
eleven other banks within its primary service area of Jefferson City and, to an
increasing extent, thirteen other banks in nearby communities. Based on publicly
available information, management believes that Exchange National Bank is the
second largest (in terms of deposits) of the banks within Cole County. The main
competition for Exchange National Bank's trust services is from other commercial
banks.


                                        4



     The areas in which Citizens Union State Bank competes for deposits and
loans are its primary service areas of Clinton, Springfield, Branson, Collins,
Lee's Summit, Osceola and Windsor, Missouri and its secondary service area of
the nearby communities in Henry, St. Clair, Greene and Jackson Counties.
Citizens Union State Bank's principal competition for deposits and loans comes
from seven other banks within its primary service area and, to an increasing
extent, sixty-four other banks in nearby communities. Based on publicly
available information, management believes that Citizens Union State Bank is the
largest (in terms of deposits) of the banks within Henry County. The main
competition for Citizens Union State Bank's trust services is from the trust
departments of other commercial banks in the Kansas City area.

     Osage Valley Bank competes for deposits and loans in its primary service
area of Warsaw, Missouri and its secondary service area of the nearby
communities in Benton County. Osage Valley Bank's principal competition for
deposits and loans comes from banks within its primary service area of Warsaw
and in nearby communities. Based on publicly available information, management
believes that Osage Valley Bank is the largest (in terms of deposits) of the
five banks within Benton County.

     Bank 10 competes for deposits and loans in its primary service area of
Belton, Drexel, Harrisonville, Independence and Raymore, Missouri and its
secondary service area of nearby communities in Cass and Jackson counties. Bank
10's principal competition for deposits and loans comes from banks within its
primary service area of Belton and in nearby communities. Based on publicly
available information, management believes that Bank 10 is the largest (in terms
of deposits) of the eighteen banks within Cass County.

REGULATION APPLICABLE TO BANK HOLDING COMPANIES

     GENERAL. As a registered bank holding company and a financial holding
company under the Bank Holding Company Act (the "BHC Act") and the
Gramm-Leach-Bliley Act (the "GLB Act"), Exchange is subject to supervision and
examination by the Federal Reserve Board (the "FRB"). The FRB has authority to
issue cease and desist orders against bank holding companies if it determines
that their actions represent unsafe and unsound practices or violations of law.
In addition, the FRB is empowered to impose civil money penalties for violations
of banking statutes and regulations. Regulation by the FRB is intended to
protect depositors of our Banks, not the shareholders of Exchange.

     LIMITATION ON ACQUISITIONS. The BHC Act requires a bank holding company to
obtain prior approval of the FRB before:

     -    taking any action that causes a bank to become a controlled subsidiary
          of the bank holding company;

     -    acquiring direct or indirect ownership or control of voting shares of
          any bank or bank holding company, if the acquisition results in the
          acquiring bank holding company having control of more than 5% of the
          outstanding shares of any class of voting securities of such bank or
          bank holding company, and such bank or bank holding company is not
          majority-owned by the acquiring bank holding company prior to the
          acquisition;

     -    acquiring substantially all of the assets of a bank; or

     -    merging or consolidating with another bank holding company.

     LIMITATION ON ACTIVITIES. The activities of bank holding companies are
generally limited to the business of banking, managing or controlling banks, and
other activities that the FRB has determined to be so closely related to banking
or managing or controlling banks as to be a proper incident thereto. In
addition, under the GLB Act, a bank holding company, all of whose controlled
depository institutions are "well capitalized" and "well managed" (as defined in
federal banking regulations) and which obtains "satisfactory" Community
Reinvestment Act ratings, may declare itself to be a "financial holding company"
and engage in a broader range of activities.


                                        5



     A financial holding company may affiliate with securities firms and
insurance companies and engage in other activities that are financial in nature
or incidental or complementary to activities that are financial in nature.
"Financial in nature" activities include:

     -    securities underwriting, dealing and market making;

     -    sponsoring mutual funds and investment companies;

     -    insurance underwriting and insurance agency activities;

     -    merchant banking; and

     -    activities that the FRB determines to be financial in nature or
          incidental to a financial activity; or which is complementary to a
          financial activity and does not pose a safety and soundness risk.

     A financial holding company that desires to engage in activities that are
financial in nature or incidental to a financial activity but not previously
authorized by the FRB must obtain approval from the FRB before engaging in such
activity. Also, a financial holding company may seek FRB approval to engage in
an activity that is complementary to a financial activity, if it shows that the
activity does not pose a substantial risk to the safety and soundness of its
insured depository institutions or the financial system.

     A financial holding company may acquire a company (other than a bank
holding company, bank or savings association) engaged in activities that are
financial in nature or incidental to activities that are financial in nature
without prior approval from the FRB. Prior FRB approval is required, however,
before the financial holding company may acquire control of more than 5% of the
voting shares or substantially all of the assets of a bank holding company, bank
or savings association. In addition, under the FRB's merchant banking
regulations, a financial holding company is authorized to invest in companies
that engage in activities that are not financial in nature, as long as the
financial holding company makes its investment with the intention of limiting
the duration of the investment, does not manage the company on a day-to-day
basis, and the company does not cross-market its products or services with any
of the financial holding company's controlled depository institutions.

     If any subsidiary bank of a financial holding company ceases to be
"well-capitalized" or "well-managed," the FRB has authority to order the
financial holding company to divest its subsidiary banks. Alternatively, the
financial holding company may elect to limit its activities and the activities
of its subsidiaries to those permissible for a bank holding company that is not
a financial holding company. If any subsidiary bank of a financial holding
company receives a rating under the Community Reinvestment Act (the "CRA") of
less than "satisfactory", then the financial holding company is prohibited from
engaging in new activities or acquiring companies other than bank holding
companies, banks or savings associations until the rating is raised to
"satisfactory" or better.

     REGULATORY CAPITAL REQUIREMENTS. The FRB has promulgated capital adequacy
guidelines for use in its examination and supervision of bank holding companies.
If a bank holding company's capital falls below minimum required levels, then
the bank holding company must implement a plan to increase its capital, and its
ability to pay dividends and make acquisitions of new bank subsidiaries may be
restricted or prohibited.

     The FRB's capital adequacy guidelines provide for the following types of
capital:

Tier 1 capital, also referred to as core capital, calculated as:

          -    common stockholders' equity;

          -    plus, perpetual preferred stock and any related surplus (limited
               to a maximum of 25% of Tier 1 capital elements);

          -    plus, minority interests in the equity accounts of consolidated
               subsidiaries.;


                                        6



          -    less, all intangible assets (other than certain mortgage
               servicing assets, non-mortgage servicing assets and purchased
               credit card relationships);

          -    less, certain credit-enhanced interest only strips and
               nonfinancial equity investments required to be deducted from
               capital; and

          -    less, certain deferred tax assets.

Tier 2 capital, also referred to as supplementary capital, calculated as:

          -    allowances for loan and lease losses (limited to 1.25% of
               risk-weighted assets);

          -    plus, unrealized gains on certain equity securities (limited to
               45% of pre-tax net unrealized gains);

          -    plus, cumulative perpetual and long-term preferred stock
               (original maturity of 20 years or more) and any related surplus
               (noncumulative and cumulative, without percentage limits);

          -    plus, auction rate and similar preferred stock (both cumulative
               and non-cumulative);

          -    plus, hybrid capital instruments (including mandatory convertible
               debt securities); and

          -    plus, term subordinated debt and intermediate-term preferred
               stock with an original weighted average maturity of five years or
               more (limited to 50% of Tier 1 capital).

     The maximum amount of supplementary capital that qualifies as Tier 2
     capital is limited to 100% of Tier 1 capital.

Total capital, calculated as:

          -    Tier 1 capital;

          -    plus, qualifying Tier 2 capital;

          -    less, investments in banking and finance subsidiaries that are
               not consolidated for regulatory capital purposes;

          -    less, intentional, reciprocal cross-holdings of capital
               securities issued by banks; and

          -    less, other deductions (such as investments in other subsidiaries
               and joint ventures) as determined by supervising authority.

     The FRB's capital adequacy guidelines require that a bank holding company
maintain a Tier 1 leverage ratio equal to at least 4% of its average total
consolidated assets, a Tier 1 risk-based capital ratio equal to 4% of its
risk-weighted assets and a total risk-based capital ratio equal to 8% of its
risk-weighted assets.

     On December 31, 2005, Exchange was in compliance with all of the FRB's
capital adequacy guidelines. Exchange's capital ratios on December 31, 2005 are
shown below:



                                    Tier 1 Risk-Based    Total Risk-Based Capital
            Leverage Ratio (3%      Capital Ratio (4%        Ratio (8% minimum
           minimum requirement)   minimum requirement)          requirement)
           --------------------   --------------------   ------------------------
                                                
Exchange           7.88%                  9.83%                   12.70%


     INTERSTATE BANKING AND BRANCHING. Under the Riegle-Neal Interstate Banking
and Branching Efficiency Act of 1994 (the "Riegle-Neal Act"), a bank holding
company is permitted to acquire the stock or substantially all of the assets of
banks located in any state regardless of whether such transaction is prohibited
under the laws of any state. The FRB will not approve an interstate acquisition
if, as a result of the


                                        7



acquisition, the bank holding company would control more than 10% of the total
amount of insured deposits in the United States or would control more than 30%
of the insured deposits in the home state of the acquired bank. The 30% of
insured deposits state limit does not apply if the acquisition is the initial
entry into a state by a bank holding company or if the home state waives such
limit. The Riegle-Neal Act also authorizes banks to merge across state lines,
thereby creating interstate branches. Banks are also permitted to acquire and to
establish de novo branches in other states where authorized under the laws of
those states.

     Under the Riegle-Neal Act, individual states may restrict interstate
acquisitions in two ways. A state may prohibit an out-of-state bank holding
company from acquiring a bank located in the state unless the target bank has
been in existence for a specified minimum period of time (not to exceed five
years). A state may also establish limits on the total amount of insured
deposits within the state which are controlled by a single bank holding company,
provided that such deposit limit does not discriminate against out-of-state bank
holding companies.

     SOURCE OF STRENGTH. FRB policy requires a bank holding company to serve as
a source of financial and managerial strength to its subsidiary banks. Under
this "source of strength doctrine," a bank holding company is expected to stand
ready to use its available resources to provide adequate capital funds to its
subsidiary banks during periods of financial stress or adversity, and to
maintain resources and the capacity to raise capital which it can commit to its
subsidiary banks. Furthermore, the FRB has the right to order a bank holding
company to terminate any activity that the FRB believes is a serious risk to the
financial safety, soundness or stability of any subsidiary bank.

     LIABILITY OF COMMONLY CONTROLLED INSTITUTIONS. Under cross-guaranty
provisions of the Federal Deposit Insurance Act (the "FDIA"), bank subsidiaries
of a bank holding company are liable for any loss incurred by the Bank Insurance
Fund (the "BIF"), the federal deposit insurance fund for banks, in connection
with the failure of any other bank subsidiary of the bank holding company.

     MISSOURI BANK HOLDING COMPANY REGULATION. Missouri prohibits any bank
holding company from acquiring ownership or control of any bank or Missouri
depository trust company that has Missouri deposits if, after such acquisition,
the bank holding company would hold or control more than 13% of total Missouri
deposits. Because of this restriction, a bank holding company, prior to
acquiring control of a bank or depository trust company that has deposits in
Missouri, must receive the approval of the Missouri Division of Finance.

REGULATION APPLICABLE TO OUR BANKS

     GENERAL. Exchange National Bank, a national bank, is subject to regulation
and examination by the OCC and the FDIC. Citizens Union State Bank, a Missouri
state non-member depository trust company, is subject to the regulation of the
Missouri Division of Finance and the FDIC. Osage Valley Bank, a Missouri state
non-member bank, is subject to the regulation of the Missouri Division of
Finance and the FDIC. Bank 10, a Missouri state non-member bank, is subject to
the regulation of the Missouri Division of Finance and the FDIC. Each of the OCC
and the FDIC is empowered to issue cease and desist orders against our Banks if
it determines that activities of any of our Banks represents unsafe and unsound
banking practices or violations of law. In addition, the OCC and the FDIC have
the power to impose civil money penalties for violations of banking statutes and
regulations. Regulation by these agencies is designed to protect the depositors
of the bank, not shareholders of Exchange.

     BANK REGULATORY CAPITAL REQUIREMENTS. The OCC and the FDIC have adopted
minimum capital requirements applicable to national banks and state non-member
banks, respectively, which are similar to the capital adequacy guidelines
established by the FRB for bank holding companies. A special risk-based capital
requirement (including a Tier 3 capital component) applies to certain large
banks whose trading activity (on a worldwide consolidated basis) equals 10% or
more of their total assets or $1 billion or more. None of our Banks is subject
to such special capital requirement:


                                        8



     -    "well-capitalized" if it has a total Tier 1 leverage ratio of 5% or
          greater, a Tier 1 risk-based capital ratio of 6% or greater and a
          total risk-based capital ratio of 10% or greater (and is not subject
          to any order or written directive specifying any higher capital
          ratio);

     -    "adequately capitalized" if it has a total Tier 1 leverage ratio of 4%
          or greater (or a Tier 1 leverage ratio of 3% or greater, if the bank
          has a CAMELS rating of 1), a Tier 1 risk-based capital ratio of 4% or
          greater and a total risk-based capital ratio of 8% or greater;

     -    "undercapitalized" if it has a total Tier 1 leverage ratio that is
          less than 4% (or a Tier 1 leverage ratio that is less than 3%, if the
          bank has a CAMELS rating of 1), a Tier 1 risk-based capital ratio that
          is less than 4% or a total risk-based capital ratio that is less than
          8%;

     -    "significantly undercapitalized" if it has a total Tier 1 leverage
          ratio that is less than 3%, a Tier 1 risk based capital ratio that is
          less than 3% or a total risk-based capital ratio that is less than 6%;
          and

     -    "critically undercapitalized" if it has a Tier 1 leverage ratio that
          is equal to or less than 2%.

     Federal banking laws require the federal regulatory agencies to take prompt
corrective action against undercapitalized financial institutions.

     On December 31, 2005, each of our Banks was in compliance with its federal
banking agency's minimum capital requirements. The capital ratios and
classifications of each of our Banks as of December 31, 2005 is shown on the
following chart.



                                     Tier 1 Risk-Based   Total Risk-Based
                    Leverage Ratio     Capital Ratio       Capital Ratio     Classification
                    --------------   -----------------   ----------------   ----------------
                                                                
Exchange National
   Bank                  9.41%             11.63%             12.88%        Well-Capitalized
Citizens Union
   State Bank            8.29%              9.82%             10.73%        Well-Capitalized
Osage Valley Bank        6.31%             10.48%             11.43%        Well-Capitalized
Bank 10                  8.24%             10.05%             10.85%        Well-Capitalized


     All of our Banks must be well-capitalized for Exchange to remain a
financial holding company.

     DEPOSIT INSURANCE AND ASSESSMENTS. The deposits of our Banks are insured by
the BIF administered by the FDIC, in general up to a maximum of $100,000 per
insured depositor. Under federal banking regulations, insured banks are required
to pay semi-annual assessments to the FDIC for deposit insurance. The FDIC's
risk-based assessment system requires that BIF members pay varying assessment
rates depending upon the level of the institution's capital and the degree of
supervisory concern over the institution. The FDIC's assessment rates range from
zero cents to 27 cents per $100 of insured deposits. The FDIC has authority to
increase the annual assessment rate and there is no cap on the annual assessment
rate which the FDIC may impose. As of January 1, 2006, the assessment rate for
each of our banks was zero cents per $100 of insured deposits.

     LIMITATIONS ON INTEREST RATES AND LOANS TO ONE BORROWER. The rate of
interest a bank may charge on certain classes of loans is limited by state and
federal law. At certain times in the past, these limitations have resulted in
reductions of net interest margins on certain classes of loans. Federal and
state laws impose additional restrictions on the lending activities of banks.
The maximum amount that a Missouri state-chartered bank may lend to any one
person or entity is generally limited to 15% of the unimpaired capital of


                                        9



the bank located in a city having a population of 100,000 or more, 20% of the
unimpaired capital of the bank located in a city having a population of less
than 100,000 and over 7,000, and 25% of the unimpaired capital of the bank if
located elsewhere in the state.

     PAYMENT OF DIVIDENDS. Our Banks are subject to federal and state laws
limiting the payment of dividends. Under the FDIA, an FDIC-insured institution
may not pay dividends while it is undercapitalized or if payment would cause it
to become undercapitalized. The National Bank Act and Missouri banking law also
prohibit the declaration of a dividend out of the capital and surplus of the
bank. These laws and regulations are not expected to have a material effect upon
the current dividend policies of our Banks.

     COMMUNITY REINVESTMENT ACT. Our Banks are subject to the CRA and
implementing regulations. CRA regulations establish the framework and criteria
by which the bank regulatory agencies assess an institution's record of helping
to meet the credit needs of its community, including low- and moderate-income
neighborhoods. CRA ratings are taken into account by regulators in reviewing
certain applications made by Exchange and its banking subsidiaries.

     LIMITATIONS ON TRANSACTIONS WITH AFFILIATES. Exchange and its non-bank
subsidiaries are "affiliates" within the meaning of the Federal Reserve Act. The
amount of loans or extensions of credit which our Banks may make to non-bank
affiliates, or to third parties secured by securities or obligations of the
non-bank affiliates, are substantially limited by the Federal Reserve Act and
the FDIA. Such acts further restrict the range of permissible transactions
between a bank and an affiliated company. A bank and its subsidiaries may engage
in certain transactions, including loans and purchases of assets, with an
affiliated company only if the terms and conditions of the transaction,
including credit standards, are substantially the same as, or at least as
favorable to the bank as, those prevailing at the time for comparable
transactions with non-affiliated companies or, in the absence of comparable
transactions, on terms and conditions that would be offered to non-affiliated
companies.

     OTHER BANKING ACTIVITIES. The investments and activities of our Banks are
also subject to regulation by federal banking agencies regarding investments in
subsidiaries, investments for their own account (including limitations on
investments in junk bonds and equity securities), loans to officers, directors
and their affiliates, security requirements, anti-tying limitations, anti-money
laundering, financial privacy and customer identity verification requirements,
truth-in-lending, the types of interest bearing deposit accounts which it can
offer, trust department operations, brokered deposits, audit requirements,
issuance of securities, branching and mergers and acquisitions.

CHANGES IN LAWS AND MONETARY POLICIES

     RECENT LEGISLATION. On July 30, 2002, President Bush signed into law the
Sarbanes-Oxley Act of 2002. The stated goals of the Sarbanes-Oxley Act are to
increase corporate responsibility, to provide the enhanced penalties for
accounting and auditing improprieties at publicly traded companies and to
protect investors by improving the accuracy and reliability of corporate
disclosures made pursuant to the securities laws. The proposed changes are
intended to allow shareholders to monitor the performance of companies and
directors more easily and efficiently.

     The Sarbanes-Oxley Act generally applies to all companies that file or are
required to file periodic reports with the SEC under the Securities and Exchange
Act of 1934. Further, the Sarbanes-Oxley Act includes very specified additional
disclosure requirements and new corporate governance rules, requires the SEC,
securities exchanges and the NASDAQ Stock Market to adopt extensive additional
disclosure, corporate governance and other related rules and mandates further
studies of certain issues by the SEC and the Comptroller General. Given the
extensive SEC role in implementing rules relating to many of the Sarbanes-Oxley
Act's new requirements, the final scope of these requirements remains to be
determined.


                                       10



     The Sarbanes-Oxley Act addresses, among other matters: audit committees;
certification of financial statements by the chief executive officer and the
chief financial officer; the forfeiture of bonuses and profits made by directors
and senior officers in the twelve month period covered by restated financial
statements; a prohibition on insider trading during pension plan black out
periods; disclosure of off-balance sheet transactions; a prohibition on personal
loans to directors and officers (excluding federally insured financial
institutions); expedited filing requirements for stock transaction reports by
officers and directors; the formation of a public accounting oversight board;
auditor independence; and various increased criminal penalties for violations of
securities laws. Management has taken various measures to comply with the
requirements of the Sarbanes-Oxley Act.

     FUTURE LEGISLATION. Various pieces of legislation, including proposals to
change substantially the financial institution regulatory system, are from time
to time introduced and considered by the Missouri state legislature and the
United States Congress. This legislation may change banking statutes and the
operating environment of Exchange in substantial and unpredictable ways. If
enacted, this legislation could increase or decrease the cost of doing business,
limit or expand permissible activities or affect the competitive balance among
banks, savings associations, credit unions and other financial institutions.
Exchange cannot predict whether any of this potential legislation will be
enacted and, if enacted, the effect that it, or any implementing regulations,
could have on Exchange's business, results of operations or financial condition.

     FISCAL MONETARY POLICIES. Exchange's business and earnings are affected
significantly by the fiscal and monetary policies of the federal government and
its agencies. Exchange is particularly affected by the policies of the FRB,
which regulates the supply of money and credit in the United States. Among the
instruments of monetary policy available to the FRB are:

     -    conducting open market operations in United States government
          securities;

     -    changing the discount rates of borrowings of depository institutions;

     -    imposing or changing reserve requirements against depository
          institutions' deposits; and

     -    imposing or changing reserve requirements against certain borrowings
          by bank and their affiliates.

     These methods are used in varying degrees and combinations to directly
affect the availability of bank loans and deposits, as well as the interest
rates charged on loans and paid on deposits. The policies of the FRB have a
material effect on Exchange's business, results of operations and financial
condition.

and regulation are merely summaries, which do not purport to be complete and

regulations.

ITEM 1A. RISK FACTORS.

RISK FACTORS

     We are identifying important risks and uncertainties that could affect our
Company's results of operations, financial condition or business and that could
cause them to differ materially from our Company's historical results of
operations, financial condition or business, or those contemplated by
forward-looking statements made herein or elsewhere, by, or on behalf of, our
Company. Factors that could cause or contribute to such differences include, but
are not limited to, those factors described below. The risk factors highlighted
below are not the only ones that our Company faces.

     BECAUSE WE PRIMARILY SERVE MISSOURI, A DECLINE IN THE LOCAL ECONOMIC
CONDITIONS COULD LOWER EXCHANGE'S PROFITABILITY. The profitability of Exchange
is dependant on the profitability of its banking subsidiaries, which operate out
of central Missouri. The financial condition of these banks is affected by
fluctuations in the economic conditions prevailing in the portion of Missouri in
which their operations are located. Accordingly, the financial conditions of
both Exchange and its banking subsidiaries would be adversely affected by
deterioration in the general economic and real estate climate in Missouri.

     An increase in unemployment, a decrease in profitability of regional
businesses or real estate values or an increase in interest rates are among the
factors that could weaken the local economy. With a weaker local economy:

     -    customers may not want or need the products and services of Exchange's
          banking subsidiaries,

     -    borrowers may be unable to repay their loans,

     -    the value of the collateral security of our banks' loans to borrowers
          may decline, and

     -    the overall quality of our banks' loan portfolio may decline.

     Making mortgage loans and consumer loans is a significant source of profits
for Exchange's banking subsidiaries. If individual customers in the local area
do not want these loans, profits may decrease. Although our banks could make
other investments, our banks may earn less revenue on these investments than on
loans. Also, our banks' losses on loans may increase if borrowers are unable to
make payments on their loans.

     INTEREST RATE CHANGES MAY REDUCE OUR PROFITABILITY AND OUR BANKING
SUBSIDIARIES. The primary source of earnings for Exchange's banking subsidiaries
is net interest income. To be profitable, our banks have to earn more money in
interest and fees on loans and other interest-earning assets than they pay as
interest on deposits and other interest-bearing liabilities and as other
expenses. If prevailing interest rates decrease, as has already happened on
several occasions since January 2001, the amount of interest our banks earn on
loans and investment securities may decrease more rapidly than the amount of
interest our banks have to pay on deposits and other interest-bearing
liabilities. This would result in a decrease in the profitability of Exchange
and its banking subsidiaries, other factors remaining equal.


                                       12



     Changes in the level or structure of interest rates also affect

     -    our banks' ability to originate loans,

     -    the value of our banks' loan and securities portfolios,

     -    our banks' ability to realize gains from the sale of loans and
          securities,

     -    the average life of our banks' deposits, and

     -    our banks' ability to obtain deposits.

     Fluctuations in interest rates will ultimately affect both the level of
income and expense recorded on a large portion of our banks' assets and
liabilities, and the market value of all interest-earning assets, other than
interest-earning assets that mature in the short term. Our banks' interest rate
management strategy is designed to stabilize net interest income and preserve
capital over a broad range of interest rate movements by matching the interest
rate sensitivity of assets and liabilities. Although Exchange believes that its
banks' current mix of loans, mortgage-backed securities, investment securities
and deposits is reasonable, significant fluctuations in interest rates may have
a negative effect on the profitability of our banks.

     OUR PROFITABILITY DEPENDS ON THEIR ASSET QUALITY AND LENDING RISKS. Success
in the banking industry largely depends on the quality of loans and other
assets. The loan officers of Exchange's banking subsidiaries are actively
encouraged to identify deteriorating loans. Loans are also monitored and
categorized through an analysis of their payment status. A recent review by our
new credit officer identified areas of concern that resulted in heightened
attention being given to reducing concentrations of credit and, in particular,
to strengthening credit quality and administration. Our banks' failure to timely
and accurately monitor the quality of their loans and other assets could have a
materially adverse effect on the operations and financial condition of Exchange
and its banking subsidiaries. There is a degree of credit risk associated with
any lending activity. Our banks attempt to minimize their credit risk through
loan diversification. Although our banks' loan portfolios are varied, with no
undue concentration in any one industry, substantially all of the loans in the
portfolios have been made to borrowers in central and west central Missouri.
Therefore, the loan portfolios are susceptible to factors affecting the central
and west central Missouri area and the level of non-performing assets is heavily
dependant upon local conditions. There can be no assurance that the level of our
banks' non-performing assets will not increase above current levels. High levels
of non-performing assets could have a materially adverse effect on the
operations and financial condition of Exchange and its banking subsidiaries.

     OUR PROVISIONS FOR PROBABLE LOAN LOSSES MAY NEED TO BE INCREASED. Each of
Exchange's banking subsidiaries make a provision for loan losses based upon
management's analysis of probable losses in the loan portfolio and consideration
of prevailing economic conditions. Each of our banks may need to increase the
provision for loan losses through additional provisions in the future if the
financial condition of any of its borrowers deteriorates or if real estate
values decline. Furthermore, various regulatory agencies, as an integral part of
their examination process, periodically review the loan portfolio, provision for
loan losses, and real estate acquired by foreclosure of each of our banks. Such
agencies may require our banks to recognize additions to the provisions for loan
losses based on their judgments of information available to them at the time of
the examination. Any additional provisions for probable loan losses, whether
required as a result of regulatory review or initiated by Exchange itself, may
materially alter the financial outlook of Exchange and its banking subsidiaries.

     IF WE ARE UNABLE TO SUCCESSFULLY COMPETE FOR CUSTOMERS IN OUR MARKET AREA,
OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS COULD BE ADVERSELY AFFECTED.
Exchange's banking subsidiaries face substantial competition in making loans,
attracting deposits and providing other financial products and services. Our
banks have numerous competitors for customers in their market area. Such
competition for loans comes principally from:


                                       13



     -    other commercial banks

     -    savings banks

     -    savings and loan associations

     -    mortgage banking companies

     -    finance companies

     -    credit unions

Competition for deposits comes principally from:

     -    other commercial banks

     -    savings banks

     -    savings and loan associations

     -    credit unions

     -    brokerage firms

     -    insurance companies

     -    money market mutual funds

     -    mutual funds (such as corporate and government securities funds)

     Many of these competitors have greater financial resources and name
recognition, more locations, more advanced technology and more financial
products to offer than our banks. Competition from larger institutions may
increase due to an acceleration of bank mergers and consolidations in Missouri
and the rest of the nation. In addition, the Gramm-Leach-Bliley Act removes many
of the remaining restrictions in federal banking law against cross-ownership
between banks and other financial institutions, such as insurance companies and
securities firms. The law will likely increase the number and financial strength
of companies that compete directly with our banks. The profitability of our
banks depends of their continued ability to attract new customers and compete in
Missouri. New competitors, as well as the expanding operations of existing
competitors, have had, and are expected to continue to have, an adverse impact
on our banks' market share of deposits and loans in our banks' respective
service areas. If our banks are unable to successfully compete, their financial
condition and results of operations will be adversely affected.

     WE MAY EXPERIENCE DIFFICULTIES IN MANAGING OUR GROWTH AND IN EFFECTIVELY
INTEGRATING NEWLY ACQUIRED COMPANIES. As part of our general strategy, Exchange
may continue to acquire banks and businesses that it believes provide a
strategic fit with its business. To the extent that our company does grow, there
can be no assurances that we will be able to adequately and profitably manage
such growth. Acquiring other banks and businesses will involve risks commonly
associated with acquisitions, including:

     -    potential exposure to liabilities of the banks and businesses
          acquired;

     -    difficulty and expense of integrating the operations and personnel of
          the banks and businesses acquired;

     -    difficulty and expense of instituting the necessary systems and
          procedures, including accounting and financial reporting systems, to
          manage the combined enterprises on a profitable basis;

     -    potential disruption to our existing business and operations;

     -    potential diversion of the time and attention of our management; and

     -    impairment of relationships with and the possible loss of key
          employees and customers of the banks and businesses acquired.

The success of our internal growth strategy will depend primarily on the ability
of our banking subsidiaries to generate an increasing level of loans and
deposits at acceptable risk levels and on acceptable terms without significant
increases in non-interest expenses relative to revenues generated. There is no
assurance that we will be successful in implementing our internal growth
strategy.

     WE MAY BE ADVERSELY AFFECTED BY CHANGES IN LAWS AND REGULATIONS AFFECTING
THE FINANCIAL SERVICES INDUSTRY. Banks and bank holding companies such as
Exchange are subject to regulation by both federal and state bank regulatory
agencies. The regulations, which are designed to protect borrowers and promote
certain social policies, include limitations on the operations of banks and bank
holding companies,


                                       14



such as minimum capital requirements and restrictions on dividend payments. The
regulatory authorities have extensive discretion in connection with their
supervision and enforcement activities and their examination policies, including
the imposition of restrictions on the operation of a bank, the classification of
assets by an institution and requiring an increase in a bank's allowance for
loan losses. These regulations are not necessarily designed to maximize the
profitability of banking institutions. Future changes in the banking laws and
regulations could have a material adverse effect on the operations and financial
condition of Exchange and its banking subsidiaries.

     OUR SUCCESS LARGELY DEPENDS ON THE EFFORTS OF OUR EXECUTIVE OFFICERS. The
success of Exchange and its banking subsidiaries has been largely dependant on
the efforts of James Smith, Chairman and CEO and David Turner, President and the
other executive officers. These individuals are expected to continue to perform
their services. However, the loss of the services of Messrs. Smith or Turner, or
any of the other key executive officers could have a materially adverse effect
on Exchange and its banks.

     WE CANNOT PREDICT HOW CHANGES IN TECHNOLOGY WILL AFFECT OUR BUSINESS. The
financial services market, including banking services, is increasingly affected
by advances in technology, including developments in:

     -    telecommunications

     -    data processing

     -    automation

     -    Internet-based banking

     -    telebanking

     -    debit cards and so-called "smart cards"

     Our ability to compete successfully in the future will depend on whether
they can anticipate and respond to technological changes. To develop these and
other new technologies our Banks will likely have to make additional capital
investments. Although our Banks continually invest in new technology, there can
be no assurance that our Banks will have sufficient resources or access to the
necessary proprietary technology to remain competitive in the future.

     ADDITIONAL FACTORS. Additional risks and uncertainties that may affect the
future results of operations, financial condition or business of our Company and
its banking subsidiaries include, but are not limited to: (i) adverse publicity,
news coverage by the media, or negative reports by brokerage firms, industry and
financial analysts regarding our Banks or our Company; and (ii) changes in
accounting policies and practices.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

     None.

ITEM 2. PROPERTIES.

     None of Exchange, Union, Mid Central Bancorp or ENB Holdings owns or leases
any property.

     The principal offices of Exchange, ENB Holdings and Exchange National Bank
are located at 132 East High Street in the central business district of
Jefferson City, Missouri. The building, which is owned by Exchange National
Bank, is a three-story structure constructed in 1927. A 1998 renovation and
expansion project increased usable office space from 14,000 square feet to
approximately 33,000 square feet. All of this office space is currently used by
Exchange and Exchange National Bank. Management believes that this facility is
adequately covered by insurance.

FORWARD-LOOKING STATEMENTS

     This report, including information included or incorporated by reference in
this report, contains certain forward-looking statements with respect to the
financial condition, results of operations, plans, objectives, strategy, future
performance and business of our Company and its subsidiaries, including, without
limitation:

     -    statements that are not historical in nature, and

     -    statements preceded by, followed by or that include the words
          "believes," "expects," "may," "will," "should," "could,"
          "anticipates," "estimates," "intends" or similar expressions.

     Forward-looking statements are not guarantees of future performance or
results. They involve risks, uncertainties and assumptions. Actual results may
differ materially from those contemplated by the forward-looking statements due
to, among others, the following factors:

     -    competitive pressures among financial services companies may increase
          significantly,

     -    costs or difficulties related to the integration of the business of
          Exchange and its acquisition targets may be greater than expected,

     -    changes in the interest rate environment may reduce interest margins,

     -    general economic conditions, either nationally or in Missouri, may be
          less favorable than expected,

     -    legislative or regulatory changes may adversely affect the business in
          which Exchange and its subsidiaries are engaged,

     -    technological changes may be more difficult or expensive than
          anticipated, and

     -    changes may occur in the securities markets.

We have described additional factors that could cause actual results to be
materially different from those described in the forward-looking statements,
which factors are identified in Item 1A of this report under the heading "Risk
Factors." Other factors that we have not identified in this report could also
have this effect. You are cautioned not to put undue reliance on any
forward-looking statement, which speak only as of the date such statement is
made. Except as otherwise required by law, we undertake no obligation to
publicly update or revise any forward-looking statement to reflect events or
circumstances after the date of this report or to reflect the occurrence of
unanticipated events.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Our Company's exposure to market risk is reviewed on a regular basis by our
Banks' Asset/Liability Committees and Boards of Directors. Interest rate risk is
the potential of economic losses due to future interest rate changes. These
economic losses can be reflected as a loss of future net interest income and/or
a loss of current fair market values. The objective is to measure the effect on
net interest income and to adjust the balance sheet to minimize the inherent
risk while at the same time maximizing income. Management realizes certain risks
are inherent and that the goal is to identify and minimize those risks. Tools
used by our Bank's management include the standard GAP report subject to
different rate shock scenarios. At December 31, 2005, the rate shock scenario
models indicated that annual net interest income could change by as much as
8.26% should interest rates rise or fall within 200 basis points from their
current level over a one year period. However there are no assurances that the
change will not be more or less than this estimate.

ITEM 9A. CONTROLS AND PROCEDURES.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES.

     Our Company's management has evaluated, with the participation of our
principal executive and principal financial officers, the effectiveness of our
disclosure controls and procedures as of December 31, 2005. Based upon and as of
the date of that evaluation, our principal executive officer and principal
financial officer concluded that our disclosure controls and procedures were
effective to ensure that information required to be disclosed in the reports we
file and submit under the Securities Exchange Act of 1934 is recorded,
processed, summarized and reported as and when required. It should be noted that
any system of disclosure controls and procedures, however well designed and
operated, can provide only reasonable, and not absolute, assurance that the
objectives of the system are met. In addition, the design of any system of
disclosure controls and procedures is based in part upon assumptions about the
likelihood of future events. Because of these and other inherent limitations of
any such system, there can be no assurance that any design will always succeed
in achieving its stated goals under all potential future conditions, regardless
of how remote.

INTERNAL CONTROLS OVER FINANCIAL REPORTING.

     MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING.

          Our Company's management is responsible for establishing and
     maintaining adequate internal control over financial reporting, as such
     term is defined in Securities Exchange Act Rules 13a-15(f). Under the
     supervision and with the participation of our management, including our
     principal executive officer and principal financial officer, we conducted
     an evaluation of the effectiveness of our internal control over financial
     reporting based on the framework in Internal Control - Integrated Framework
     issued by the Committee of Sponsoring Organizations of the Treadway
     Commission. Based on our evaluation under the framework in Internal Control
     - Integrated Framework, our Company's management concluded that our
     internal control over financial reporting was effective as of December 31,
     2005. Our management's assessment of the effectiveness of our internal
     control over financial reporting as of December 31, 2005 has been audited
     by KPMG LLP, an independent registered public accounting firm, as stated in
     their report which is included herein.

     REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

     The Board of Directors and Shareholders
     Exchange National Bancshares, Inc.:

     We have audited management's assessment, as set forth above, that Exchange
     National Bancshares, Inc. and subsidiaries (the Company) maintained
     effective internal control over financial reporting as of December 31,
     2005, based on criteria established in Internal Control--Integrated
     Framework issued by the Committee of Sponsoring Organizations of the
     Treadway Commission (COSO). The Company's management is responsible for
     maintaining effective internal control over financial reporting and for its
     assessment of the effectiveness of internal control over financial
     reporting. Our responsibility is to express an opinion on management's
     assessment and an opinion on the effectiveness of the Company's internal
     control over financial reporting based on our audit.

     We conducted our audit in accordance with the standards of the Public
     Company Accounting Oversight Board (PCAOB) (United States). Those standards
     require that we plan and perform the audit to obtain reasonable assurance
     about whether effective internal control over financial reporting was
     maintained in all material respects. Our audit included obtaining an
     understanding of internal control over financial reporting, evaluating
     management's assessment, testing and evaluating the design and operating
     effectiveness of internal control, and performing such other procedures as
     we considered necessary in the circumstances. We believe that our audit
     provides a reasonable basis for our opinion.

     A company's internal control over financial reporting is a process designed
     to provide reasonable assurance regarding the reliability of financial
     reporting and the preparation of financial statements for external purposes
     in accordance with generally accepted accounting principles. A company's
     internal control over financial reporting includes those policies and
     procedures that (1) pertain to the maintenance of records that, in
     reasonable detail, accurately and fairly reflect the transactions and
     dispositions of the assets of the company; (2) provide reasonable assurance
     that transactions are recorded as necessary to permit preparation of
     financial statements in accordance with generally accepted accounting
     principles, and that receipts and expenditures of the company are being
     made only in accordance with authorizations of management and directors of
     the company; and (3) provide reasonable assurance regarding prevention or
     timely detection of unauthorized acquisition, use, or disposition of the
     company's assets that could have a material effect on the financial
     statements.

     Because of its inherent limitations, internal control over financial
     reporting may not prevent or detect misstatements. Also, projections of any
     evaluation of effectiveness to future periods are subject to the risk that
     controls may become inadequate because of changes in conditions, or that
     the degree of compliance with the policies or procedures may deteriorate.

     In our opinion, management's assessment that Exchange National Bancshares,
     Inc. maintained effective internal control over financial reporting as of
     December 31, 2005 is fairly stated, in all material respects, based on
     criteria established in Internal Control--Integrated Framework issued by
     COSO. Also, in our opinion, Exchange National Bancshares, Inc. maintained,
     in all material respects, effective internal control over financial
     reporting as of December 31, 2005, based on criteria established in
     Internal Control-- Integrated Framework issued by COSO.

     We also have audited, in accordance with the standards of the PCAOB (United
     States), the consolidated balance sheets of Exchange National Bancshares,
     Inc. and subsidiaries as of December 31, 2005 and 2004, and the related
     consolidated statements of income, stockholders' equity


                                       21



     and comprehensive income, and cash flows for each of the years in the
     three-year period ended December 31, 2005, and our report dated March 13,
     2006 expressed an unqualified opinion on those consolidated financial
     statements.

     CHANGES IN INTERNAL CONTROLS.

          There has been no change in our Company's internal control over
     financial reporting that occurred during the fiscal quarter ended December
     31, 2005 that has materially affected, or is reasonably likely to
     materially affect, our internal control over financial reporting.
