                    INFORMATION ABOUT THE MEETING AND VOTING

PURPOSE OF THE MEETING

     The purposes of the annual meeting are:

     -    to elect three Class II directors to hold office for a term expiring
          at the 2009 annual meeting of the shareholders of our Company;

     -    to consider and vote upon ratification and approval of the selection
          of the accounting firm of KPMG LLP as the independent auditors of our
          Company for the current year; and

     -    to transaction such other business as may properly come before the
          annual meeting, including a proposal to adjourn or postpone the
          meeting.

SHAREHOLDERS ENTITLED TO VOTE AT THE MEETING

     Shareholders of record as of the close of business on the April 7, 2006
record date are entitled to notice of, and to vote at, the annual meeting or any
adjournment or adjournments thereof. As of the record date, 4,169,847 shares of
our Company's common stock were issued and outstanding and an additional 128,506
shares were issued and held in treasury. Each issued and outstanding share of
common stock as of the record date is entitled to one vote on each matter
properly to come before the annual meeting.

ATTENDING THE MEETING AND VOTING IN PERSON

     If you plan to attend the annual meeting and vote in person, we will give
you a ballot when you arrive. However, if your shares are held in the name of
your broker, bank or other nominee (commonly referred to as being held in
"street" name), proof of ownership may be required for you to be admitted to the
meeting. A recent brokerage statement or letter from a bank or broker are
examples of proof of ownership. If you want to vote your shares of common stock
held in street name in person at the meeting, you will have to get a written
proxy in your name from the broker, bank or other nominee who holds your shares.



VOTING BY PROXY

     This proxy statement is being sent to you by our board of directors for the
purpose of requesting that you allow your shares of common stock to be
represented at the annual meeting by the persons named in the enclosed proxy
card. You may complete, date and sign the enclosed form of proxy and return it
promptly in the enclosed postage prepaid envelope. Alternatively, you may direct
how your shares are to be voted by telephone or Internet. In that event, please
follow the instructions accompanying the enclosed form of proxy. If you properly
complete and sign your proxy card and send it to us in time to vote or properly
provide your voting instructions by telephone or Internet prior to the annual
meeting, your shares will be voted as you have directed. If you sign the proxy
card but do not make specific voting instructions, your shares will be voted as
follows:

     -    "FOR" the election of the nominees for director named in this proxy
          statement, and

     -    "FOR" ratification of the selection of the accounting firm of KPMG LLP
          as our Company's independent auditors for the current year.

     If any other matter is properly brought before the annual meeting, your
shares will be voted in accordance with the discretion and judgment of the
appointed proxies. A shareholder who has given a proxy may revoke it at any time
before it is exercised at the annual meeting by filing written notice of
revocation with the Secretary of our Company, by executing and delivering to the
Secretary of our Company a proxy bearing a later date, or by appearing at the
annual meeting and voting in person.

     If your shares of common stock are held in street name, you will receive
instructions from your broker, bank or other nominee that you must follow in
order to have your shares voted. Your broker or bank may allow you to deliver
your voting instructions via the telephone or the Internet.

QUORUM REQUIREMENT

     A quorum of shareholders is necessary to hold a valid meeting. The presence
in person or by proxy of shareholders holding a majority of the total
outstanding shares of our Company's common stock will constitute a quorum at the
annual meeting. Shares of common stock represented by a proxy which directs that
the shares be voted to abstain or to withhold a vote on any matter will be
counted in determining whether a quorum is present. Shares of common stock as to
which there is a broker non-vote (i.e., when a broker holding shares for clients
in street name is not permitted to vote on certain matters without instruction)
also will be counted for quorum purposes. If a quorum should not be present, the
annual meeting may be adjourned from time to time until a quorum is obtained.

REQUIRED VOTE TO APPROVE EACH PROPOSAL

     Election of Directors. Directors are elected by a majority of the votes
cast, in person or by proxy, of shareholders entitled to vote at the annual
meeting for that purpose. Shareholders can withhold authority to vote for one or
more nominees for director. Votes withheld from a particular nominee will have
the same effect as a vote against the nominee. Shareholders do not have
cumulative voting rights in the election of directors.

     Selection of Auditors and Other Matters. The affirmative vote of a majority
of the shares of our Company's common stock, represented in person or by proxy
and entitled to vote at the annual meeting, is required for (i) the ratification
of the selection of KPMG LLP as our Company's independent auditors, and (ii) the
approval of such other matters as properly may come before the annual meeting or
any adjournment thereof. Shareholders can abstain from voting on these
proposals. If you abstain from voting on any of these proposals, it has the same
effect as a vote against the proposal.

     Effect of Broker Non-Votes. If your broker does not vote your shares on any
proposal, such "broker non-votes" do not count as shares present for purposes of
such proposal. This means that a broker non-vote would reduce the number of
affirmative votes that are necessary to approve the proposal.


                                        2



SOLICITATION OF PROXIES

     This solicitation of proxies for the annual meeting is being made by our
Company's board of directors. Our Company will bear all costs of such
solicitation, including the cost of preparing and mailing this proxy statement
and the enclosed form of proxy. After the initial mailing of this proxy
statement, proxies may be solicited by mail, telephone, facsimile transmission
or personally by directors, officers, employees or agents of our Company,
Exchange National Bank, Citizens Union State Bank, Osage Valley Bank or Bank 10.
Brokerage houses and other custodians, nominees and fiduciaries will be
requested to forward soliciting materials to beneficial owners of shares held of
record by them, and their reasonable out-of-pocket expenses, together with those
of our Company's transfer agent, will be paid by our Company.

     A list of shareholders entitled to vote at the annual meeting will be
available for examination at least ten days prior to the date of the annual
meeting during normal business hours at the registered office of our Company
located at 132 East High Street, Jefferson City, Missouri. The list also will be
available at the annual meeting.

                          ITEM 1: ELECTION OF DIRECTORS

THE BOARD OF DIRECTORS

     Our Company's board of directors consists of eight directors. The articles
of incorporation of our Company divides the board of directors into three
classes of directors, with the directors serving staggered terms of three years
and until their respective successors are duly elected and qualified or until
their respective earlier resignation or removal. The present terms of David R.
Goller, James R. Loyd and Gus S. Wetzel, II, the three directors in Class II,
expire at this annual meeting. Directors in Class I (Charles G. Dudenhoeffer,
Jr., Philip D. Freeman and James E. Smith) and Class III (Kevin L. Riley and
David T. Turner) have been elected to terms expiring at the time of the annual
meeting of shareholders in 2008 and 2007, respectively.

     One of the purposes of this annual meeting is to elect three directors in
Class II to serve for a three-year term expiring at the annual meeting of
shareholders in 2009 and until their respective successors are duly elected and
qualified or until their respective earlier resignation or removal. The
Nominating and Corporate Governance Committee of our board of directors has
designated David R. Goller, James R. Loyd and Gus S. Wetzel, II as the three
nominees proposed for election at the annual meeting. Unless authority to vote
for the nominees or a particular nominee is withheld, it is intended that the
shares represented by properly executed proxies in the form enclosed will be
voted for the election as directors of these three nominees. In the event that
one or more of the nominees should become unavailable for election, it is
intended that the shares represented by the proxies will be voted for the
election of such substitute nominee or nominees as may be designated by the
Nominating and Corporate Governance Committee, unless the authority to vote for
all nominees or for the particular nominee who has ceased to be a candidate has
been withheld. Each of the nominees has indicated his willingness to serve as a
director if elected, and the board of directors has no reason to believe that
any nominee will be unavailable for election.

     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF DAVID
R. GOLLER, JAMES R. LOYD AND GUS S. WETZEL, II AS CLASS II DIRECTORS.

NOMINEES AND DIRECTORS CONTINUING IN OFFICE

     The following table sets forth certain information with respect to each
person nominated by the board of directors for election as a Class II director

COMPENSATION OF DIRECTORS

     Only outside (non-employee) members of our Company's board of directors
receive compensation for their service to our Company as a director. Each of
these outside (non-employee) directors receives $600 for each meeting of the
Board attended. Each member of our Company's Audit Committee receives $700 for
each committee meeting attended. Each member of our Company's Compensation
Committee receives $300 for each meeting attended. Each member of our Company's
Nominating and Corporate Governance Committee receives $300 for each meeting
attended.

     All directors of our Company (other than Mr. Wetzel) are also directors of
Exchange National Bank, and in that capacity may receive compensation from
Exchange National Bank. Each of Exchange National Bank's outside (non-employee)
directors is paid a monthly $500 retainer and $300 for each meeting of the Board
attended in person. In addition, these directors are eligible for a $2,400 bonus
if Exchange National Bank meets certain financial goals and the director attends
at least 80% of the Board meetings held (which could include one telephone
conference meeting). With the exception of Mr. Goller, all of Exchange National
Bank's non-employee directors received this bonus for 2005. Currently, any
director deferring receipt of this bonus will have 124 shares of Exchange
National Bank stock imputed to his account under the Exchange National Bank's
Director Deferred Compensation Plan on the last day of the year. These imputed
shares accumulate from year to year but do not represent actual shares or the
right to receive payment of the value of such shares. Each year the director is
credited an amount in his Plan account equal to Exchange National Bank's net
income per share multiplied by the number of imputed shares in the director's
Plan account as of the beginning of the year.

     Three of our Company's directors -- Mr. Smith, Mr. Turner and Mr. Wetzel --
also are directors of Citizens Union State Bank. Mr. Smith and Mr. Turner are
not eligible to receive compensation for their service to Citizens Union State
Bank as a director. For his service to Citizens Union State Bank as a director,
Mr. Wetzel is paid a quarterly $300 retainer plus $300 for each meeting of the
Board that he attends in person. Mr. Wetzel also receives $100 for each meeting

MEETINGS OF THE BOARD AND COMMITTEES

     BOARD OF DIRECTORS. During 2005 the board of directors of our Company held
4 regular, 3 special and 1 reorganization meeting. During 2005, each director
attended at least 75% of the regular meetings of the board of directors and of
the committees of the board on which he served. Our Company's directors
discharge their responsibilities throughout the year, not only at such board of
directors and committee meetings, but through personal meetings and other
communications with members of management and others regarding matters of
interest and concern to our Company.

     Directors are encouraged by our Company to attend our annual meeting of
shareholders if their schedules permit, but our Company does not otherwise have
a policy regarding such attendance. All directors were present at the annual
meeting of the shareholders held in June 2005. The board of directors typically
meets immediately following the annual meeting of shareholders, which
facilitates the directors' ability to attend the annual meeting of shareholders.

     COMMITTEES. Our Company's board of directors has established an Audit
Committee, a Compensation Committee and a Nominating and Corporate Governance
Committee. There currently are no other standing compensation, executive,
nominating or other committees of our Company's board of directors, or
committees performing similar functions of the Board.

     Audit Committee. The Audit Committee assists the Board in fulfilling its
responsibilities with respect to accounting and financial reporting practices
and the scope and expense of audit and related services provided by external
auditors, among others. The Audit Committee is responsible for apprising the
Board of management's compliance with Board mandated policies, internal
procedures and applicable laws and regulations. The committee works with the
internal audit department and external auditors and supervises the internal
audit function directly, reviews and approves the hiring of audit personnel and
evaluates the performance of the internal audit function and the external
auditors. The committee also has the duty to make, or cause to be made, a
suitable examination and audit of the financial affairs of our Company and its
subsidiaries at least annually, and to report thereon to the board of directors.
A more complete description of the Audit Committee's functions is provided in
its charter, a copy of which was attached to the proxy statement with respect to
the 2004 annual meeting of shareholders. A copy of the charter also is available
on our internet website (www.exchangebancshares.com) under "Governance
Documents." Members of the Audit Committee currently are Messrs. Freeman,
Goller, Loyd, Riley and Wetzel, each of whom satisfies the definition of an
"independent" director as established in the National Association of Securities
Dealers listing standards. The Board of Directors has determined that Messrs.
Goller and Loyd qualify as "audit committee financial experts" within the
meaning of the rules and regulations of the Securities and Exchange Commission.
The Audit Committee met 10 times during 2005.

     Compensation Committee. In January 2000, our Company established a
Compensation Committee which assumed the responsibility to make recommendations
to the board of directors regarding the compensation and benefits of our
executive officers and directors and the establishment and administration of our
Company's executive compensation program. In June 2003, our board of directors
expanded the responsibilities of the Compensation Committee to include the
construction, interpretation and administration of our Incentive Stock Option
Plan, and to exercise exclusive authority over the grant of options under the
Plan. A more complete description of the Compensation Committee's functions is
provided in its charter, a copy of which is available on our internet website
(www.exchangebancshares.com) under "Governance Documents." Members of the
Compensation Committee currently are Messrs. Freeman, Goller, Loyd, Riley and
Wetzel. The Compensation Committee met 8 times during 2005.

     Nominating and Corporate Governance Committee. In May 2004, our board of
directors authorized the establishment of a Nominating and Corporate Governance
Committee, although the members of this committee were not appointed until June
2005. This committee is responsible for the director nomination process,
including evaluating and recommending director nominees and Board committee
appointments, and is responsible for various other governance related matters,
including an annual Board assessment. A more complete description of the
committee's functions is provided in its charter, a copy of which is available
on our internet website (www.exchangebancshares.com) under "Governance
Documents." Members of the Nominating and Corporate Governance Committee
currently are Messrs. Dudenhoeffer, Freeman, Goller, Loyd, Riley and Wetzel,
each of


                                        6



whom satisfies the definition of an "independent" director as established in the
National Association of Securities Dealers listing standards. The Nominating and
Corporate Governance Committee met 2 times during 2005.

SELECTION OF NOMINEES FOR THE BOARD OF DIRECTORS

     In identifying and evaluating director nominees, the Nominating and
Corporate Governance Committee may receive recommendations from management, from
other directors and from shareholders (in accordance with the procedures
described under "Advance Notice of Shareholder Proposals"). The committee
reviews information on each candidate and evaluates it in light of the needs and
requirements of our Company. The committee believes that the Board and its
committees should be comprised of persons who are of high character and
integrity, who have a personal and professional reputation that is consistent
with the image and reputation of our Company, and who have expertise that may be
useful to our Company. The committee considers various factors, including the
independence of the candidate, as well as his or her education or special
skills, areas of expertise, experience, age, business associations, reputation
and other characteristics and qualities that the committee believes are likely
to enhance the effectiveness of the Board and its committees. In determining
whether a director should be retained and stand for re-election, the committee
also considers the director's past attendance at meetings and participation in
and contributions to the activities of the Board.

     As more fully described under "Advance Notice of Shareholder Proposals,"
our Company's articles of incorporation and bylaws provide a mechanism for
shareholders to use in submitting nominations for Board membership. The
Nominating and Corporate Governance Committee's policy is to consider nominees
who are submitted in accordance with that mechanism. Each such nominee will be
considered on a case by case basis. All nominees, including those submitted by
shareholders, will be evaluated using generally the same methods and criteria
described above, although those methods and criteria are not standardized and
may vary from time to time.

SHAREHOLDER COMMUNICATIONS WITH DIRECTORS

     Our board of directors has not established a formal process for
shareholders to follow to send communications to the Board or its members, as
our Company's policy has been to forward to the directors any shareholder
correspondence it receives that is addressed to them. Shareholders who wish to
communicate with our directors may do so by sending their correspondence
addressed to the director or directors at our Company's headquarters at 132 East
High Street, Jefferson City, Missouri 65101.

                  EXECUTIVE COMPENSATION AND OTHER INFORMATION

REPORT ON EXECUTIVE COMPENSATION

     This report has been prepared by the Compensation Committee of our
Company's board of directors (the "Committee") which has general responsibility
for the establishment, direction and administration of all aspects of the
compensation policies and programs for the executive officers of our Company and
its affiliate banks. Under agreements between our Company and subsidiary banks,
individuals who are employees of both our Company and one of our subsidiary
banks are compensated as such by the appropriate subsidiary bank. Our Company's
executive compensation program, insofar as it pertains to the Chairman of the
Board and Chief Executive Officer (the "Chief Executive Officer") and the
President (the "President") of our Company, is administered by the Committee.
The Committee is composed of five independent outside directors, none of whom is
an officer or employee of our Company or any affiliate bank. Our Company's
executive compensation program, insofar as it pertains to executive officers
other than the Chief Executive Officer and the President, is administered by the
Chief Executive Officer and the President. Mr. James Smith, the Chief Executive
Officer, and certain other executive officers of our Company and affiliate
banks, may attend meetings of the Committee, but are not present during
discussions or deliberations regarding their own compensation.

     COMPENSATION POLICY. Our Company's executive compensation policy is
premised upon three basic goals: (1) to attract and retain qualified individuals
who provide the skills and leadership necessary to enable our Company and its
affiliate banks to achieve earnings growth, capital compliance and return on
investment objectives, while maintaining a commitment to equal employment
opportunity and affirmative action guidelines and practices; (2) to create
incentives to achieve company and individual performance objectives through the
use of performance-based


                                        7



compensation programs; and (3) to create a mutuality of interest between
executive officers and shareholders through compensation structures that create
a direct link between executive compensation and shareholder return.

     In determining the structure and levels of each of the components of
executive compensation needed to achieve these goals, all elements of the
compensation package are considered in total, rather than any one component in
isolation. As more fully described below, the determination of such levels of
executive compensation is a subjective process in which many factors are
considered, including our Company's and/or affiliate banks' performance and the
individual executive's specific responsibilities, historical and anticipated
personal contribution to our business, and length of service with our Company or
affiliate banks.

     COMPENSATION COMPONENTS. The Committee, as well as the Chief Executive
Officer and the President, reviews our Company's compensation program annually
to ensure that compensation levels and incentive opportunities are competitive
and reflect the performance of our Company and its affiliate banks as well as
performance of the individual executive officer. The particular elements of the
compensation program for executive officers are base salary, incentive
compensation and periodic stock option grants. The Committee believes that these
compensation components together advance both the short- and long-term interests
of our shareholders. In this regard, the Committee believes that the long-term
interests of our shareholders are advanced by designating a portion of executive
compensation to be at risk: namely, incentive compensation (which permits
individual performance to be recognized on an annual and long-term basis based,
in part, on an evaluation of the executive's contribution to our Company's
and/or affiliate bank's performance) and the grant of stock options (which
directly ties a portion of the executive's long-term remuneration to stock price
appreciation realized by shareholders). Each of the components of the
compensation program is addressed separately below.

     Base Salary. The base salary for each executive officer is reviewed from
the previous year. In determining whether to adjust base salary levels,
management's recommendations and subjective assessments of each executive's
growth and effectiveness in the performance of his or her duties are taken into
account. In addition, the performance of our Company and/or the affiliate bank
is considered. The increases in the base salaries of executives of our Company
and affiliate banks for 2005 were based primarily upon a subjective analysis of
our Company's and/or the banks' performance during the period since the last
salary increase and the individual executive's role in generating that
performance. In this regard, the analysis of performance included a review of
our Company's and/or affiliate bank's earnings and return on investment for the
prior year. The analysis of the role played by each individual executive in
generating our Company's and/or bank's performance included a consideration of
the executive's specific responsibilities, contributions to our Company's and/or
bank's business, and length of service. The factors impacting base salary levels
are not independently assigned specific weights. Rather, all of these factors
are reviewed, and specific base pay recommendations are made which reflect an
analysis of the aggregate impact of these factors. The Committee and the Chief
Executive Officer and the President believe that base pay levels for the
executive officers are maintained within a range that is considered to be
appropriate and necessary.

     Incentive Compensation. After careful analysis of our Company's needs and
an examination of the competitive practices among peer companies, the Committee
recommended, and the full board of directors approved, the adoption of an
incentive bonus program. As a result, our Company's and affiliate banks'
officers are eligible to receive incentive bonus awards. Each of the officers
who are eligible to receive bonus awards are assigned to one of four bonus
tiers, which assignments are made primarily according to job category. Tier one
consists of the Chief Executive Officer. Tier two consists of our Company's
President and affiliate bank presidents. Tier three consists of senior officers
of our Company and affiliate banks. Tier four includes officers of affiliate
banks.

     Officers identified by the Chief Executive Officer and the President and
the Committee are eligible to receive incentive bonuses. These officers may earn
annual awards only upon the achievement of performance objectives which are
established at the beginning of the year. Threshold, target and maximum levels
of awards are established, and no awards are paid if the threshold is not met.
The performance objectives are weighted based upon their relative importance to
each individual. The performance objectives for participants may include
corporate performance objectives and personal targeted objectives for
performance. The performance objectives may include functional or operating unit
objectives. Each participant's target bonus is expressed as a percentage of his
or her base salary, dependent on responsibility and function. The target award
is 30% of base salary in the case of the Chief Executive Officer, and in the
case of the Presidents, senior officers and other officers, the target award
ranges


                                        8



from 10% to 20% of base pay. Earned awards may range from 0% to 150% of the
target award. In 2005, the Committee granted an incentive bonus award of
$75,000, or 27.6% of base pay, to Mr. Smith for 2004.

     Incentive bonus awards to the Presidents are allocated based upon the
recommendation of the Chief Executive Officer. In allocating bonus awards among
the other participants, the Chief Executive Officer and our Company's President
exercise their discretion and judgment after considering the individual
participant's performance, responsibilities and contributions to our Company
and/or affiliate banks, and subjectively analyzing the basis of their aggregate
impact on the success of our Company and/or affiliate banks for the preceding
year.

     Stock Options. The Committee believes that in order to enhance long-term
shareholder value it must provide incentives that provide motivation beyond
short-term results. In February 2000, our board of directors adopted, and our
shareholders subsequently approved, a stock option plan. The objective of stock
option grants is to advance the longer term interests of our Company and its
shareholders and complement incentives tied to annual performance by rewarding
executives upon the creation of incremental shareholder value. Stock options
only produce value to executives if the price of our Company' common stock
appreciates, thereby directly linking the interests of executives with those of
shareholders. Therefore, in order to provide long-term incentives to executive
officers and other employees related to long-term growth in the value of our
Company's common stock, it is intended that stock options be granted to such
persons under our Company' stock option plan. The selection of the persons
eligible to receive stock options and the designation of the number of stock
options to be granted to such persons are made by our Company's Compensation
Committee after taking into account management's assessment of each person's
relative level of authority and responsibility with the Bank, years of service
and base salary, among other factors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Members of the Compensation Committee are Mr. Freeman, the Chairman, Mr.
Goller, Mr. Loyd, Mr. Riley and Dr. Wetzel, II. As discussed above under "Report
on Executive Compensation", in 2005 Mr. Smith, the Chief Executive Officer,
administered the executive compensation program insofar as it pertained to
executive officers other than the Chief Executive Officer. All decisions
relating to the compensation of executive officers are reviewed by, and subject
to the approval of, the Compensation Committee. Among the members of the banks'
board of directors, Mr. Smith and Mr. Turner are officers and employees of the
Company and affiliate banks.

     None of the members of the Committee were an officer or employee of our
Company or any of its subsidiaries during 2005. Messrs. Loyd, Riley and Wetzel,
and certain corporations and firms in which such persons have interests, have
obtained loans from the affiliate banks. Each of such loans are believed to have
been made to such persons, corporations or firms in the ordinary course of
business, on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
other persons, and did not involve more than the normal risk of collectability
or present other unfavorable features.

(1)  All stock options are incentive stock options.

(2)  All grants were made at 100% of the fair market value as of the grant date.

(3)  The dollar amounts under these columns are the result of calculations at
     the 5% and 10% assumed annual growth rates mandated by the Securities and
     Exchange Commission and, therefore, are not intended to forecast possible
     future appreciation, if any, in the common stock price. The calculations
     were based on the exercise prices and the 10-year term of the options. No
     gain to the optionees is possible without an increase in stock price which
     will benefit all shareholders proportionately. The "Potential Realizable
     Value" to all Exchange shareholders as a group which would result from the
     application of the same assumptions to the 4,169,847 shares of common stock
     outstanding at December 31, 2005, at the $29.51 per share fair market value
     of our Company's common stock on the last trading day of 2005 is an
     incremental gain of $0, $77,392,360 and $196,107,904 for 0%, 5% and 10%,

PROFIT-SHARING 401(K) PLAN

     Exchange National Bank established a profit-sharing plan and trust in 1951
which has been amended and restated from time to time and was most recently
amended effective April 1, 2005.

     All employees of the controlled group of corporations (namely, Exchange
National Bancshares, Exchange National Bank, Citizens Union State Bank, Osage
Valley Bank and Bank 10) who have completed one year of service and attained age
21 are eligible to participate in the plan. The members of the controlled group
may make a discretionary contribution to the trust associated with the plan. In
general, the contributions by members of the controlled group to the trust for
any given year are allocated to the accounts of the participants in direct
proportion to the compensation of the participants for such year. The plan
permits eligible participants to make elective deferrals up to a maximum dollar
amount as set forth by law. These deferrals and earnings thereon are fully
vested. There is no employer match to such deferrals.

     Each participant may direct the trustee as to investment of his or her
account. At the direction of a participant, the trustee can "invest" assets in a
participant's account in our Company's common stock. Each participant may direct
the trustee with respect to the voting of shares of our Company's stock
allocated to his account on such matters upon which shareholders are entitled to
vote. As of March 1, 2006, the trust held 138,202 shares (or 3.31%) of our
Company's common stock.

     The interest of a participant in employer contributions is subject to
graded vesting over five years. After five years a participant becomes fully
vested in the value of his or her employer contribution account. A participant
whose employment terminates because of his or her normal retirement, death, or
permanent disability is also fully vested. Payments are made to participants
upon termination of service. A participant may withdraw his or her own
contributions, but a participant may not borrow from the trust. The plan and the
trust is administered by a retirement committee which is appointed by our
Company's board of directors. As of December 31, 2005, the trust held assets
with an aggregate market value of $11,888,080.

STOCK OPTION PLAN

     On February 29, 2000, our board of directors adopted the Exchange National
Bancshares, Inc. Incentive Stock Option Plan. The Plan is sponsored by our
Company for key employees of our Company and its subsidiaries, and is intended
to encourage such employees to participate in the ownership of our Company, and
to provide additional incentive for them to promote the success of our business
through sharing in the future growth of our business. As of March 1, 2006,
options to purchase a total of 161,556 shares of common stock pursuant to the
Plan were outstanding.

     The Plan is administered by a committee composed of Messrs. Freeman,
Goller, Riley, Loyd and Wetzel. The Plan committee has the power to determine in
its discretion the persons to whom options are granted under the Plan, the
number of shares covered by those options, and the time at which an option
becomes exercisable, subject in each case to the limitations set forth in the
Plan. Options can be granted under the Plan only to key employees of our Company
or any of its subsidiary corporations. The eligibility of the persons to whom
options may be granted under the Plan is limited to those persons whom the Plan
committee determines have made, or are expected to make, material contributions
to the successful performance of our Company. The period of up to ten years
during which an option may be exercised, and the time at which it becomes
exercisable, are fixed by the Plan committee at the time the option is granted.
No option granted under the Plan is transferable by the holder other than by
will or the laws of descent and distribution.

     The aggregate number of shares of our common stock that may be issued
pursuant to the exercise of options granted under the Plan is limited to 450,000
shares, subject to increase or decrease in the event of any change in our
Company's capital structure. As of March 1, 2006, options for 267,052 shares
remained available for


                                       12



grant under the Plan. Shares subject to options granted under the Plan which
expire or terminate without being exercised in full become available, to the
extent unexercised, for future grants under the Plan. No consideration is paid
to our Company by any optionee in exchange for the grant of an option. The per
share exercise price for an option granted under the Plan is determined by the
Plan committee but may not be less than the greater of the par value or the fair
market value of our common stock on the date that the option is granted. The
Plan provides for automatic adjustments to prevent dilution or enlargement of
the optionee's rights in the event of a stock split, stock dividend,
reorganization, merger, consolidation, liquidation, combination or exchange of
shares, or other change in the capital structure of our Company.

PENSION PLAN

     Concurrently with the creation of the profit-sharing plan and trust in
1951, Exchange National Bank established a defined benefit plan for its
employees, which has been amended and restated from time to time, and was most
recently amended and restated effective July 1, 2005. Under the plan, all
full-time employees become participants on the earlier of the first of June or
the first of December coincident with or immediately following the later to
occur of (i) the completion of one year of service or (ii) the attainment of the
age of 21, and continue to participate so long as they continue to be full-time
employees, until their retirement, death or termination of employment prior to
normal retirement date. The plan has a five-year vesting schedule under which a
participant becomes fully vested in his accrued benefit after completing five
years of service. This plan provides for the payment of retirement and death
benefits that are funded by investments which, at December 31, 2005, had an
aggregate market value of $5,772,553.

     Effective July 1, 2005, participation in the plan was expanded.
Participation in the plan had been limited to eligible employees of our Company
and Exchange National Bank. Effective July 1, 2005 the plan was amended and
restated so that participation was extended to eligible employees of Citizens
Union State Bank, Osage Valley Bank and Bank 10 - referred to as the "Adopting
Employers". Past service for employees of such Adopting Employers is counted for
eligibility, vesting and benefit accrual subject to limitations.

     The normal retirement benefits provided under the plan for an employee with
at least 25 years of continuous service are based upon 45% of his/her average
compensation over a ten-year period, less 50% of his social security benefit.
Compensation covered by the plan prior to January 1, 2005 included wages,
salaries and overtime pay and deferrals but excluded directors' fees,
commissions, bonuses, expense allowances and other extraordinary compensation.
For the plan years beginning on and after January 1, 2005 compensation covered
by the plan is an employee's W-2 compensation plus deferrals under the cafeteria
plan and 401(k) plan. Amounts reported in the compensation table include
salaries, directors' fees, commissions and bonuses. For employees with less than
25 years of continuous service, retirement benefits are reduced proportionally.
Provision is made for early or late retirement and optional payment provisions
are available.

     The table below illustrates the projected amount of annual retirement
income, based on a straight line annuity, available under the plan for a person
retiring at 65 years of age at various levels of average annual compensation and
years of service classifications, with an assumed annual social security benefit
of $10,000.



AVERAGE TEN-
YEAR ANNUAL    10 YEARS   15 YEARS   20 YEARS   25 YEARS
COMPENSATION    SERVICE    SERVICE    SERVICE    SERVICE
------------   --------   --------   --------   --------

 200,000         34,000     51,000     68,000    85,000


     The amounts shown above reflect benefits payable in the normal payment
form. For a married participant, payment is by monthly benefit to the
participant during his or her lifetime, and 50% of that amount is paid to the
spouse monthly during the spouse's life after the participant's death. For an
unmarried participant, payment is by a lifetime monthly benefit, with payments
guaranteed for the first 120 months.


                                       13



     Mr. Turner has 27 years of service under the plan. Mr. Smith has 8 years of
service under the plan. Mr. Rose has 8 years of service under the plan.

SMITH EMPLOYMENT AGREEMENT

     Our Company has entered into an employment agreement with James E. Smith.
The agreement had an initial three-year term which expired on November 3, 2000,
but is subject to automatic extensions of one additional year upon the
expiration of each year prior to Mr. Smith's 62nd birthday (unless either party
gives notice not to so extend the term). The agreement provides for an
annualized base salary of $110,000, and eligibility for merit-based increases.
In addition to base salary, the agreement also provides that Mr. Smith is
eligible to participate in bonus and other incentive compensation plans made
available to employees having responsibilities comparable to those of Mr. Smith.

     Mr. Smith's employment is subject to early termination in the event of his
death, disability or adjudication of legal incompetence, and otherwise may be
terminated only for cause (as defined). The employment agreement prevents Mr.
Smith from competing with our Company, soliciting customers or hiring employees
during the term of the agreement and for a period of two years thereafter. In
addition, the employment agreement requires Mr. Smith to maintain the
confidentiality of our Company's confidential information prior to its
disclosure by our Company.

CHANGE OF CONTROL AGREEMENT

     Our Company has entered into change of control agreements with 25 executive
officers, including Messrs. Smith, Turner and Rose. These agreements provide
that if, within two years after a change in control (as defined below), our
Company or any subsidiary that is the primary employer of the executive
terminates the executive's employment other than by reason of the executive's
death, disability or for cause (as defined) or if the executive terminates his
or her employment for good reason (as defined), the executive will be entitled
to receive:

     -    an amount equal to two to three years' of the executive's salary
          (based on the executive's highest monthly base salary for the
          preceding twelve-month period);

     -    an amount equal to two to three times the executive's incentive bonus
          for the preceding year;

     -    the proportionate amount of any incentive bonus and other
          compensation, payments and benefits which would otherwise have been
          received by the executive for the year in which employment was
          terminated; and

     -    any accrued and unpaid vacation pay.

The total payments made under the change of control agreements and under any
other agreements, plans or arrangements as a result of a change in control is
not permitted to be in excess of 5% of the aggregate cash consideration that our
shareholders would receive as a result of a change of control. Our Company will
reimburse the executive for any excise taxes that result from any of such
payments being considered "excess parachute payments" under Section 280G of the
Internal Revenue Code of 1986, and will make a gross-up payment to reimburse the
executive for any income or other tax attributable to the excess parachute
payment and to the tax reimbursement payments themselves. The change of control
agreements require the executives to maintain the confidentiality of our
confidential information prior to its disclosure by our Company.

     A "change in control" generally is defined to take place when (a) a person
or group (other than our Company and various affiliated persons or entities)
becomes the beneficial owner, directly or indirectly, of 50% or more of the
total voting power of our Company's outstanding securities, (b) our shareholders
approve a merger or consolidation involving our Company in which at least 50% of
the total voting power of the voting securities of the surviving corporation is
held by persons who were not previously shareholders of our Company, or (c) our
shareholders approve a plan of complete liquidation of our Company or an
agreement for the sale or disposition by our Company of all or substantially all
of its assets.

     The officers and directors of our Company and of its subsidiaries, some of
their family members and our Companies with which some of the directors are
associated, were customers of, and had banking transactions with, Exchange
National Bank, Citizens Union State Bank, Osage Valley Bank and Bank 10 in the
ordinary course of each Bank's respective businesses during 2005. During that
year Exchange National Bank, Citizens Union State Bank, Osage Valley Bank and
Bank 10 each continued its policy of making loans and loan commitments in the
ordinary course of business to its employees, officers and directors, and their
affiliates, only on substantially the same terms, including interest rates,
collateral and repayment terms, as those prevailing at the time for comparable
transactions with other persons. In the opinion of the board of directors of
Exchange National Bank, Citizens Union State Bank, Osage Valley Bank and Bank
10, respectively, none of its transactions with such persons involved more than
a normal risk of collectability or other unfavorable features.

     Jeffrey C. Smith, the son of James E. Smith, our Company's Chairman of the
Board and Chief Executive Officer, is employed by Citizens Union State Bank as
the Senior Vice President of its Lee's Summit branch. Sarah C. Wagoner, the
daughter of James E. Smith, also is employed by Citizens Union State Bank. The
salary, bonus and other benefits provided to Jeffrey Smith and Sarah Wagoner
during 2005 were comparable to those provided to other similarly situated
employees of our Company and its affiliated banks.

                                     ITEM 2

                RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Audit Committee of our board of directors has selected the independent
registered public accounting firm of KPMG LLP as our Company's independent
auditors to audit the books, records and accounts of our Company for the year
ending December 31, 2006. In connection with the audit of the 2006 financial
statements, our Company entered into an engagement agreement with KPMG LLP which
set forth the terms by which KPMG LLP will perform audit services for our
Company. That agreement is subject to alternative dispute resolution procedures.
Shareholders will have an opportunity to vote at the annual meeting on whether
to ratify the Audit Committee's decision in this regard.

     KPMG LLP has served as our Company's independent auditors since our Company
commenced business operations in 1993. A representative of KPMG LLP is expected
to be present at the annual meeting. Such representative will have an
opportunity to make a statement if he or she desires to do so and will be
available to respond to appropriate questions.

     Submission of the selection of the independent auditors to the shareholders
for ratification will not limit the authority of the Audit Committee to appoint
another independent certified public accounting firm to serve as independent
auditors if the present auditors resign or their engagement otherwise is
terminated. Shareholder ratification of the Audit Committee's selection of KPMG
LLP as our Company's independent auditors is not required by any statute or
regulation or by our Company's bylaws. Nevertheless, if the shareholders do not
ratify the selection of KPMG LLP at the annual meeting, the selection of
independent auditors for the current year will be reconsidered by the Audit
Committee.

     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE
SELECTION OF KPMG LLP.

     The following table presents fees for professional audit services rendered

AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES

     Pursuant to its charter, the Audit Committee of our board of directors is
responsible for reviewing and approving, in advance, any audit and any
permissible non-audit engagement or relationship between our Company and its
independent auditors. Our engagement of KPMG LLP to conduct the audit of our
Company for 2005 was approved by the Audit Committee on March 11, 2005.
Additionally, each permissible non-audit engagement or relationship between our
Company and KPMG LLP entered into since January 1, 2005 has been reviewed and
approved by the Audit Committee. All audit-related tax and other fees were
pre-approved by the Audit Committee. We have been advised by KPMG LLP that
substantially all of the work done in conjunction with its audit of our
financial statements for the most recently completed fiscal year was performed
by permanent full time employees and partners of KPMG LLP.

AUDIT COMMITTEE REPORT TO SHAREHOLDERS

     The Audit Committee of our board of directors assists the Board in
fulfilling its responsibilities with respect to accounting and financial
reporting practices and the scope and expense of audit and related services
provided by external auditors, among others. The Audit Committee is composed of
five directors. All committee members satisfy the definition of an "independent"
director as established in the National Association of Securities Dealers
listing standards, and the Board of Directors has determined that Messrs. Goller
and Loyd qualify as "audit committee financial experts" within the meaning of
the rules and regulations of the Securities and Exchange Commission. The Audit
Committee has adopted a written charter. In connection with the review and
reassessment of the adequacy of the Audit Committee's charter by the members of
the Audit Committee and management, the Audit Committee revised the Audit
Committee charter on June 11, 2003. A copy of the revised Audit Committee
charter was attached to the proxy statement with respect to the 2004 annual
meeting of shareholders. On June 8, 2005, the charter was reviewed and approved
without change by the Audit Committee.

     In connection with these responsibilities, the Audit Committee reviewed,
and met with management to discuss, the December 31, 2005 financial statements.
The Audit Committee also discussed with the independent accountants the matters
required by Statement on Auditing Standards No. 61, Codification of Statements
on Auditing Standards. The Audit Committee received written disclosures from the
independent accountants required by Independence Standards Board Standard No. 1,
Independence Discussions with Audit Committees, and the Audit Committee
discussed with the independent accountants that firm's independence. The Audit
Committee has considered whether the services provided under other non-audit
services are compatible with maintaining the independence of KPMG LLP.


                                       18



     Based upon the Audit Committee's discussions with management and the
independent accountants, and the Audit Committee's review of the representations
of management, the Audit Committee recommended that the board of directors
include the audited consolidated financial statements in the Company's Annual
Report on Form 10-K for the year ended December 31, 2005, to be filed with the
Securities and Exchange Commission.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934 requires our Company's
directors and executive officers, and persons who own more than 10% of any class
of equity securities of our Company registered pursuant to Section 12 of the
Exchange Act, to file with the Securities and Exchange Commission initial
reports of ownership and reports of changes in ownership in such securities and
other equity securities of our Company. Securities and Exchange Commission
regulations require directors, executive officers and greater than 10%
shareholders to furnish our Company with copies of all Section 16(a) reports
they file.

     To our Company's knowledge, based solely on review of the copies of such
reports furnished to our Company and written representations that no other
reports were required, during the year ended December 31, 2005, all Section
16(a) filing requirements applicable to its directors, executive officers and
greater than 10% shareholders were complied with on a timely basis, except that
Mr. Taylor was late in filing a change in beneficial ownership on Form 4 which
reported two transactions totaling 200 shares.

                          OTHER BUSINESS OF THE MEETING

     The board of directors is not aware of, and does not intend to present, any
matter for action at the annual meeting other than those referred to in this
proxy statement. If, however, any other matter properly comes before the annual
meeting or any adjournment, it is intended that the holders of the proxies
solicited by the board of directors will vote on such matters in their
discretion in accordance with their best judgment.

                                  ANNUAL REPORT

     Our Company's Annual Report to Shareholders, containing consolidated
financial statements for the year ended December 31, 2005, is being mailed with
this proxy statement to all shareholders entitled to vote at the annual meeting.
Such Annual Report is not to be regarded as proxy solicitation material.

     A COPY OF OUR COMPANY'S ANNUAL REPORT ON FORM 10-K FOR THE YEAR ENDED
DECEMBER 31, 2005, EXCLUDING EXHIBITS, WILL BE FURNISHED WITHOUT CHARGE TO ANY
SHAREHOLDER OF RECORD AS OF APRIL 7, 2006, UPON WRITTEN REQUEST TO KATHLEEN L.
BRUEGENHEMKE, EXCHANGE NATIONAL BANCSHARES, INC., 132 EAST HIGH STREET,
JEFFERSON CITY, MISSOURI 65101. Our Company will provide a copy of any exhibit
to the Form 10-K report to any such person upon written request and the payment
of our Company's reasonable expenses in furnishing such exhibits. You may read
and download our Form 10-K, including exhibits, as well as our other SEC filings
over the internet from several commercial document retrieval services as well as
at the SEC's internet website (www.sec.gov).

                         HOUSEHOLDING OF PROXY MATERIALS

     The SEC has adopted rules that permit companies and intermediaries
(including brokers) to satisfy the delivery requirements for proxy statements
and annual reports with respect to two or more shareholders sharing the same
address by delivering a single proxy statement addressed to those shareholders.
This process, which is commonly referred to as "householding," potentially means
extra convenience for shareholders and cost savings for companies.


                                       19



     This year, a number of brokers with account holders who are shareholders of
our Company will be "householding" our proxy materials. A single proxy statement
may be delivered to multiple shareholders sharing an address unless contrary
instructions have been received from one or more of the affected shareholders.
Once you have received notice from your broker that it will be "householding"
communications to your address, "householding" will continue until you are
notified otherwise or until you notify your broker or us that you no longer wish
to participate in "householding." If, at any time, you no longer wish to
participate in "householding" and would prefer to receive a separate proxy
statement and annual report in the future you may (1) notify your broker, (2)
direct your written request to: Kathleen L. Bruegenhemke, Exchange National
Bancshares, Inc., 132 East High Street, Jefferson City, MO 65101, or (3) contact
Kathleen L. Bruegenhemke at (573) 761-6179. Shareholders who currently receive
multiple copies of the proxy statement at their address and would like to
request "householding" of their communications should contact their broker. In
addition, we will promptly deliver, upon written or oral request to the address
or telephone number above, a separate copy of the annual report and proxy
statement to a shareholder at a shared address to which a single copy of the
documents was delivered.

                  SHAREHOLDER PROPOSALS FOR 2007 ANNUAL MEETING

     It is anticipated that the 2007 annual meeting of shareholders will be held
on June 13, 2007. Any shareholder who intends to present a proposal at the 2007
annual meeting must deliver the proposal to our Company at 132 East High Street,
Jefferson City, Missouri 65101, Attention: President by the applicable deadline
below:

-    If the shareholder proposal is intended for inclusion in our Company's
     proxy materials for that meeting pursuant to Rule 14a-8 under the
     Securities Exchange Act of 1934, our Company must receive the proposal no
     event later than December 28, 2006. Such proposal must also comply with the
     other requirements of the proxy solicitation rules of the Securities and
     Exchange Commission.

-    If the shareholder proposal is to be presented without inclusion in our
     Company's proxy materials for that meeting, our Company must receive the
     proposal no event later than April 15, 2007 in accordance with the advance
     notice provisions of our Company's articles of incorporation and bylaws.
     See "Advance Notice of Shareholder Proposals."

Proxies solicited in connection with the 2007 annual meeting of shareholders
will confer on the appointed proxies discretionary voting authority to vote on
shareholder proposals that are not presented for inclusion in the proxy
materials unless the proposing shareholder notifies our Company by April 15,
2007 that such proposal will be made at the meeting.

                     ADVANCE NOTICE OF SHAREHOLDER PROPOSALS

     Our Company's articles of incorporation and bylaws provide that advance
notice of shareholder nominations for the election of directors or other
business must be given. With respect to this annual meeting, written notice of
the shareholder's intent to make a nomination at the meeting must be received by
our Company's Secretary at Exchange National Bancshares, Inc., 132 East High
Street, Jefferson City, MO 65101 not later than the close of business on May 9,
2006. At future meetings of shareholders, notice of nominations or other
business to be brought before the meeting must be delivered to our Company's
Secretary at the same address not less than 60 days (30 days in the case of
nominations for the election of directors) prior to the first anniversary of the
previous year's annual meeting. In the event that the date of the annual meeting
of shareholders is advanced by more than 30 days or delayed by more than 60 days
from such anniversary date, however, notice by the shareholder to be timely must
be so delivered not later than the close of business on the later of (i) the
60th day (in the case of nominations, the 30th day) prior to such annual meeting
or (ii) the tenth day following the date on which public announcement of the
date of such meeting is first made.

     The shareholder's notice of nomination must contain (i) the name and
address of the nominating shareholder, of each person to be nominated and of the
beneficial owner (as defined in the articles of incorporation), if any, on whose
behalf the nomination is made, (ii) a representation that the nominating
shareholder is the holder of record of our Company's common stock entitled to
vote in the election of directors at the meeting and intends to appear at the
meeting to nominate the person or persons specified in the notice, (iii) the
number of shares of our Company's common stock owned beneficially and of record
by the nominating shareholder and by each person to be


                                       20



nominated, (iv) a description of all arrangements or understandings between the
nominating shareholder and each nominee and any other person or persons (naming
such person or persons) pursuant to which the nomination or nominations are to
be made by the shareholder, (v) the consent of each nominee to serve as a
director if so elected, and (vi) such other information regarding each nominee
proposed by the nominating shareholder as would be required to be included in a
proxy statement filed pursuant to the proxy rules of the Securities and Exchange
Commission, as then in effect, if our Company were soliciting proxies for the
election of such nominees. If no such notice has been received, the chairman of
the annual meeting is entitled to refuse to acknowledge the nomination of any
person which is not made in compliance with the foregoing procedure. The board
of directors does not know if, and has no reason to believe that, anyone will
attempt to nominate another candidate for director at this annual meeting.

                                        By Order of the Board of Directors
