Item 9. Regulation FD Disclosure

     On October 3, 2002, Mahaska Investment Company (the "Registrant") executed
a Stock Purchase Agreement to acquire all of the outstanding common and
preferred shares of Belle Plaine Service Corp. of Belle Plaine, Iowa in a 100%
cash transaction. Belle Plaine Service Corp. is the parent company of Citizens
Bank and Trust Company. The value of the all cash transaction is estimated to be
$6.8 million at closing.

     The transaction is subject to the approval of all of the shareholders of
Belle Plaine Service Corp. and the receipt of the required regulatory approvals.
The transaction will formally close when all of such approvals have been
received. The Registrant expects the transaction to be completed prior to
December 31, 2002.

     To finance the purchase, the Registrant recently issued $10 million in
Trust Preferred Securities through a pooled trust preferred which is co-managed
by Howe Barnes Investments, Inc. of Chicago, Illinois.

     The assets of Citizens Bank and Trust Company which are being indirectly
acquired through the acquisition of the common and preferred shares of Belle
Plaine Service Corp. constitute all of the material assets for continuation of
the existing banking operations. Citizens State Bank had total deposits of $65.8
million and total assets of $76.7 million as of June 30, 2002. The assets to be
acquired include the real estate, equipment and normal operating assets and
liabilities of Citizens Bank and Trust Company. Registrant intends to continue
to devote such assets for the continued banking operations of Citizens Bank and
Trust Company.

     When all conditions precedent to closing have been satisfied and the
transaction is closed, the Registrant contemplates filing an additional Form 8-K
disclosing the information required by Items 2 and 7 of Form 8-K.

     The information contained in this document and other financial reports may
contain forward-looking statements about the Registrant's growth and acquisition
strategies, new products and services, and future financial performance.
Forward-looking statements are encouraged by the Private Securities Litigation
Reform Act of 1995. Such forward-looking information is based upon certain
underlying assumptions, risks and uncertainties. Because of the possibility of
change in the underlying assumptions, actual results could differ materially
from these forward-looking statements. Risks and uncertainties that may affect
future results include: pricing pressures on loans and deposits, actions of bank
and non-bank competitors, changes in local and national economic conditions,
changes in regulatory requirements, actions of the Federal Reserve Board, and
customer's acceptance of the Registrant's products and services. The Registrant
undertakes no obligation to revise or update such statements to reflect current



events or circumstances after the date hereof or to reflect the occurrence of
unanticipated events.
