                       EXCHANGE NATIONAL BANCSHARES, INC.
                     ANNOUNCES AGREEMENT TO ACQUIRE BANK 10

                                  News Release

     JEFFERSON CITY, MO., February 28, 2005. Exchange National Bancshares, Inc.
(Nasdaq: EXJF), a multi-bank holding company headquartered in Jefferson City and
having bank subsidiary offices in Jefferson City, Clinton, Warsaw and other
locations in central and western Missouri, has entered into an agreement to
purchase Bank 10, Belton, Missouri, for approximately $32 million. Bank 10, with
assets of approximately $171 million, has offices in Belton, Drexel,
Harrisonville, Independence and Raymore. When consummated, the transaction will
bring the total assets of the Exchange organization to approximately $1.123
billion.

     James E. Smith, Chairman of Exchange, in making the joint announcement with
Bank 10 CEO Joe Balentine, stated that Exchange was delighted to be expanding
into some of the fastest growing areas surrounding Kansas City. Smith commented
that "The double bonus in the transaction for us is to join with the outstanding
board, officers and employees of Bank 10. I have known Joe Balentine for a long
time and his approach to banking closely mirrors our own." Smith said that
Exchange's plans were for Bank 10 to continue to operate as an independent
entity under its own name and with Joe Balentine as CEO.

     Balentine said that he purposefully did not place his bank on the market,
but indicated to Exchange last fall that if they were interested he might be
willing to listen. Balentine said "In deference to our employees and customers,
if we were to sell, I wanted to affiliate with an out-of-market community
banking group that would be interested in our organization, and not just our
customers. The other criterion was that we were only interested in joining a
quality group whose culture and philosophy are compatible with those we have
developed at Bank 10. Exchange easily met both requirements."

     Bank 10's capital accounts at December 31 totaled $13.64 million, and its
2004 pretax Subchapter S income was $2.88 million. Restated on an after-tax
basis, Bank 10 would have had net income for the year of approximately $1.87
million. Smith said that he expected the transaction to be immediately accretive
to Exchange's earnings per share.

     Bank 10 was been one of the faster growing banks in the Kansas City area in
recent years, growing from approximately $98.52 million in assets at the end of
1999 to $171.74 million on December 31, 2004. The transaction is subject to
Federal Reserve approval and certain other conditions and is expected to be
consummated on or about May 1.
