            OLD KENT WILL ACQUIRE CFSB BANCORP, INC.

   Old Kent to Become Number One in Deposit Market Share and
Residential Mortgage Lending in Michigan's State Capital

   Grand Rapids, Michigan - David J. Wagner, Chairman, President
and CEO of Old Kent Financial Corporation, and Robert H. Becker,
President and CEO of CFSB Bancorp, Inc., announced today that
they have signed a definitive agreement for the merger of CFSB
Bancorp into Old Kent.

   CFSB Bancorp is a holding company headquartered in Lansing,
Michigan, with assets of $880 million and deposits of $587
million as of December 31, 1998.  It is the parent of Community
First Bank.  CFSB Bancorp provides banking services in the
greater Lansing area through 16 offices in Ingham, Clinton,
Eaton, and Ionia Counties.

   This acquisition will triple Old Kent's deposit market share
in Lansing, making Old Kent the leading provider of financial
services in Michigan's fourth largest market.  Wagner stated,
"This acquisition underscores Old Kent's commitment to growth
and our confidence in this market.  Community First is a quality
banking organization with a culture that is very similar to
ours.  We look forward to providing Lansing area customers with
an even broader array of services and the additional convenience
of over 230 offices and 400 ATMs throughout Michigan, Illinois,
and Indiana."

   The merger is subject to approval by CFSB Bancorp
shareholders and regulatory agencies.  It is expected to be
completed in the third quarter of 1999.


    Mr. Becker commented, "We're very pleased to be affiliating
with Old Kent.  Their ability to deliver a wide variety of
financial products and services will bring added value to our
customers.  Our shareholders will benefit as they become owners
of one of the largest and most reputable financial service
organizations in the country, an organization with a 40 year
history of consecutive annual increases in per share earnings
and dividends."
 
    The merger is intended to be structured as a "pooling-of-
interests" for accounting purposes and as a tax free exchange of
shares.  CFSB Bancorp shareholders will receive 5.4 million
shares of Old Kent stock, using an exchange ratio of 0.6222 for
each share of CFSB Bancorp.  Old Kent anticipates approximately
$10 million of one-time merger related charges.  Based on the
current market value of Old Kent stock, the total value of the
transaction would be $242 million, which represents
approximately $28.00 per share.  The combined company is
expected to have a market capitalization of nearly $5 billion.

    The merger agreement contains a provision which would allow
CFSB Bancorp the right to terminate the planned merger, if Old
Kent's average common stock price falls below certain
predetermined levels, prior to closing.  The merger agreement
also provides Old Kent with an option to purchase 19.99% of CFSB
Bancorp shares under certain specified circumstances.

    Old Kent also noted that its stock repurchase program would
be unaffected by this proposed transaction.  This program was
authorized in June 1998.  Through February 23, 1999, the
Corporation had repurchased approximately 4.2 million shares of
Old Kent Common Stock, or about 70% of the total 6 million
shares authorized for reacquisition.  Under this program, shares
intended for anticipated future stock dividends are reacquired
ratably on a quarterly basis.  Also, shares intended for reissue
in connection with dividend reinvestment and employee stock
plans are reacquired quarterly as needed to maintain shares
reserved for those purposes at a level consistent with
anticipated permissible needs.  At February 19, 1999, Old Kent
had remaining authorization to repurchase approximately 1.8
million of shares of its stock over the next five months.

    Old Kent is a financial services company headquartered in
Grand Rapids, Michigan.  It operates 235 banking offices in
Michigan, Illinois, and Indiana as well as over 140 mortgage
lending sites throughout the United States.  At December 31,
1998, Old Kent assets totaled $16.6 billion.
