                                  PRESS RELEASE
FOR RELEASE July 26, 2005, at 11:00 a.m. Central Standard Time

               Iowa First Bancshares Corp. Reports Second Quarter
               --------------------------------------------------
                     Financial Results and Dividend Payment
                     --------------------------------------

Iowa First Bancshares  Corp.  (OTCBB IFST) today reported net income of $923,000
for the quarter ended June 30, 2005,  compared to net income of $988,000 for the
quarter ended June 30, 2004, a decrease of $65,000 or 6.6%. This decrease in net
income resulted from increased  operating  expenses and lower other income which
more than offset  improved net interest  income and a lower  provision  for loan
losses.

Basic and diluted  earnings  per share were $.67 for the three months ended June
30,  2005,  $.04 or 5.6%  less  than the same  period  in  2004.  The  Company's
annualized  return on average  assets  for the  second  quarter of 2005 was .97%
compared to 1.04%  during the second  quarter of the prior year.  The  Company's
annualized return on average equity for the three months ended June 30, 2005 and
June 30, 2004 was 14.0% and 15.7%, respectively.

The Company  recorded net income of $1,689,000 for the six months ended June 30,
2005, compared with net income of $1,811,000 for the two quarters ended June 30,
2004,  a decrease  of  $122,000 or 6.7%.  This  decrease in net income  resulted
primarily  from higher  operating  expenses and  provisions for loan losses more
than offsetting an increase in net interest income.

Basic and diluted  earnings  per share were $1.22 for the six months  ended June
30,  2005,  $.07 or 5.4%  less  than the same  period  in  2004.  The  Company's
annualized  return on average assets for the first two quarters of 2005 was .90%
compared to .96%  during the same  quarters  of the prior  year.  The  Company's
annualized  return on average  equity for the six months ended June 30, 2005 and
June 30, 2004 was 13.0% and 14.4%, respectively.

The  Company's  assets at June 30,  2005  totaled  $376,429,000,  an increase of
$12,246,000  or  3.4%  from  December  31,  2004.  Net  loans  outstanding  grew
$6,930,000 (2.5%) and total deposits increased $12,598,000 million (4.5%) during
the first six months of 2005.  Approximately  six million  dollars of loans were
sold into the  secondary  market over the six months  ended June 30,  2005.  The
allowance for loan losses totaled  $3,456,000 at June 30, 2005, or 1.2% of gross
loans outstanding.

The net interest margin increased to 3.55% during the first two quarters of 2005
compared to 3.40% during the first two  quarters of 2004.  The return on average
interest-earning  assets  increased 29 basis points (from 5.39% in 2004 to 5.68%
in 2005) while interest paid on average  interest-bearing  liabilities increased
20 basis points (from 2.33% in 2004 to 2.53% in 2005).

The board of directors declared a $.25 per common share cash dividend to be paid
to  shareholders of record June 28, 2005. This dividend will be paid on July 26,
2005 and results in an  annualized  yield of 2.8% on the December 31, 2004 stock
price.
