Item 5.  Other Events

On November 10, 1998, United Security Bancorporation (USBN)
entered into an Agreement and Plan of Merger (Merger
Agreement) with Bancwest Financial Corporation (Bancwest)
and its wholly-owned subsidiary, Bank of the West (Bank).
Under the terms of the Merger Agreement, Bancwest will be
merged with and into USBN, and the Bank will become a wholly-
owned subsidiary of USBN.

The Merger Agreement provides that USBN's common stock will
be exchanged for shares of Bancwest's common stock pursuant
to a fixed exchange ratio, which will be adjusted to account
for any net income Bancwest generates between January 1,
1999 and the date on which the merger is consummated.  The
aggregate value of the consideration is approximately $33.3
million.

In connection with the acquisition, USBN and Bancwest also
entered into a Stock Option Agreement dated November 10,
1998 (Option Agreement) whereby Bancwest granted USBN an
option to purchase 19.9% of Bancwest's common stock at a
price of $45 per share.  The Option Agreement is exercisable
upon the occurrence of certain transactions, all of which
generally involve significant sales of Bancwest's assets
and/or voting control to third parties.

Consummation of the transaction is subject to several
conditions, including receipt of applicable regulatory
approvals and approval by shareholders of USBN and Bancwest.
For information regarding the terms of the proposed
transaction, reference is made to the Merger Agreement, the
Option Agreement and the press release dated November 10,
1998, which are attached to this Report as Exhibits 2, 10
and 99, respectively, and incorporated by reference.
