                       EXCHANGE NATIONAL BANCSHARES, INC.
                     OF JEFFERSON CITY, MISSOURI, ANNOUNCES
                 1st QUARTER DILUTED EARNINGS OF $0.54 PER SHARE

JEFFERSON CITY, MO, May 6, 2004 - Today, Exchange National Bancshares, Inc.
(NASDAQ: EXJF) reported first quarter diluted earnings of $0.54 per share,
compared to $0.56 per share a year ago. Net income for the three months ended
March 31, 2004 of $2,294,000 decreased $61,000 when compared to the first
quarter of 2003.

In commenting on earnings performance, Chairman and CEO James E. Smith said
"While earnings were slightly less than the comparable quarter last year, we are
encouraged that net interest income increased $658,000 while non-interest
expense only increased $172,000. The decrease in net income resulted from a
decline in non-interest income of $525,000, which is primarily the result of a
decrease of loans sold into the secondary market. For the first quarter of 2004,
loans sold in the secondary market decreased from $30,973,000 to $13,032,000 and
that affected our gains on the sale of mortgage loans. This reflects the overall
decrease in the mortgage lending refinancing industry that is occurring
nationally.

Total assets at March 31, 2004 were $901 million, net loans were $575 million,
and total deposits were $680 million. During the quarter, the Company completed
a


                                       5

$25 million trust preferred security offering. Proceeds from the offering will
be used to finance expansion into growing metropolitan areas and to provide
capital for internal growth.
