Item 5.  Other Events
- ---------------------

On February 24, 1999, CFSB Bancorp, Inc., a Delaware corporation
("CFSB"), entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Old Kent Financial Corporation, a
Michigan corporation, pursuant to which CFSB will merge with and
into Old Kent (the "Merger").  As a result of the Merger, each
outstanding share of CFSB's common stock, par value $0.01 per
share ("CFSB Common Stock"), will be converted into the right to
receive 0.6222 shares of common stock of Old Kent, par value $1
per share ("Old Kent Common Stock").  The Merger is conditioned
upon, among other things, approval by holders of a majority of
CFSB Common Stock and the receipt of certain regulatory and
governmental approvals.  It is intended that the Merger will be
treated as a pooling-of-interests for accounting and financial
reporting purposes.  For more information, reference is made to
the Merger Agreement attached as Exhibit 2.1 hereof.

Concurrently with their execution and delivery of the Merger
Agreement, CFSB and Old Kent entered into a stock option
agreement (the "Stock Option Agreement") pursuant to which CFSB
granted Old Kent the right, upon the terms and subject to the
conditions set forth in the Stock Option Agreement, to purchase
up to 1,645,364 shares (or 19.99%) of CFSB Common Stock at a
price of $21.00 per share, subject to certain adjustments.  For
more information, reference is made to the Stock Option
Agreement attached as Exhibit 2.2.

For more information, a copy of a Press Release, dated February
24, 1999, issued by CFSB and Old Kent relating to the Merger is
attached as Exhibit 99.1 and is incorporated herein by
