EXCHANGE NATIONAL BANCSHARES ANNOUNCES YEAR 2005 ANNUAL EARNINGS OF $2.36 PER
DILUTED SHARE

Jefferson City, MO
February 24, 2006

Exchange National Bancshares, Inc. of Jefferson City, MO (NASDAQ: EXJF)
announced today for the year ended December 31, 2005, Exchange National
Bancshares, Inc. earned $2.36 per diluted share, up 19.2% from diluted earnings
of $1.98 per share a year earlier. Net income for the year ended December 31,
2005 of $9,915,000 increased $1,610,000 when compared to the year ended 2004.

In commenting on earnings, James E. Smith, Chairman and CEO said, "We had a
strong year in 2005. On May 2, 2005, we completed the purchase of Bank 10 of
Belton, MO and that purchase enhanced our already strong balance sheet position
by providing $157 million in additional earning assets. Due to an increase in
our net interest margin and in the volume of earning assets, net interest income
increased $5,963,000 compared to the same period in 2004. The net interest
margin increased from 3.43% for 2004 to 3.50% for 2005." Mr. Smith added,
"Increases in net interest income were accompanied by additional increases in
noninterest income of $1,533,000, of which the majority of the increase is
attributed to the acquisition of Bank 10. The income growth was partially offset
by a $4,985,000 increase in noninterest expense, a $380,000 increase in the 2005
loan loss provision expense and a $520,000 increase in income tax expense."

For the year, return on average equity was 10.47% and the return on average
assets was 0.91% compared to 9.16% and 0.93%, respectively for 2004.

Comparing December 31, 2005 balances to December 31, 2004, total assets
increased 21.9% to $1,126,334,000. Loans net of allowance for loan losses grew
27.9% to $804,450,000, while investment securities increased 4.6% to
$179,692,000. Total deposits increased 21.3% to $881,455,000. Subordinated notes
increased 92.0% to $49,486,000. Proceeds from the increased debt were used to
finance the Bank 10 acquisition. During the same period, stockholders' equity
increased 5.4% to $96,733,000 or 8.6% of total assets.
