IOWA FIRST BANCSHARES CORP. ANNOUNCES PLAN TO END SEC REPORTING

(Muscatine,  Iowa) - July 22, 2005 - Iowa First Bancshares Corp. announced today
that its Board of Directors  has approved a plan to proceed with a going private
transaction.  If the proposed  transaction  is completed,  Iowa First expects to
have fewer than 300 shareholders of record.  As a result,  Iowa First Bancshares
Corp. would no longer be required to file periodic reports and other information
with the Securities  and Exchange  Commission,  although Iowa First  anticipates
that its stock will continue to be traded on the Over the Counter Market.

"In addition to anticipated  cost savings  resulting from the elimination of our
SEC reporting requirements, we expect that the reduced burden on management will
allow our  officers to focus more  attention  on serving our  customers  and the
communities  where we  operate.  We believe  this also will help us achieve  our
institution's  long-term goals for growth and profitability"  stated Chairman D.
Scott Ingstad.

The  terms of the  proposed  transaction  are  expected  to  provide  that  each
shareholder of record with less than 1,000 shares of Iowa First Bancshares Corp.
common stock will receive a cash payment equal to $38.00 per share. Shareholders
of record  holding  1,000 or more  shares of Iowa  First  common  stock will not
receive a cash payment and will continue to hold the same number of shares after
completion of the transaction.

The  Board of  Directors  has  received  from a  qualified  financial  advisor a
valuation report and a fairness  opinion that the cash  consideration to be paid
in the proposed split  transaction is fair,  from a financial  point of view, to
Iowa First's shareholders. The proposed split transaction is subject to approval
by the holders of a two-thirds  majority of the issued and outstanding shares of
Iowa First Bancshares Corp. common stock.  Shareholders will be asked to approve
the split transaction at a special meeting of shareholders,  currently  expected
to be held in the fourth-quarter of 2005.


Iowa First  Bancshares Corp.  intends to file a preliminary  proxy statement and
Schedule  13E-3 with the SEC outlining the  transaction.  All  shareholders  are
advised to read the definitive  proxy  statement and Schedule 13E-3 at the SEC's
web site at  www.sec.gov.  Iowa  First  will also mail a copy of the  definitive
proxy  statement prior to the special  meeting to its  shareholders  entitled to
vote at the meeting.

The directors, executive officers and certain other members of management of the
Company  may be  soliciting  proxies  in favor  of the  proposed  going  private
transaction  from  the  Company's  shareholders.  For  information  about  these
directors,  executive  officers and members of  management,  please refer to the
Company's  Annual  Report on Form 10-K for the fiscal  year ended  December  31,
2004,  which  is  available  at the  SEC's  website  (www.sec.gov)  and from the
Company.
