                              ANNOUNCE MERGER PLANS

                    OLD FLORIDA TO EXPAND TO NAPLES, FLORIDA

FORT MYERS, FL - - Old Florida Bankshares, Inc. ("Old Florida") and Marine
Bancshares, Inc. ("Marine") today jointly announced their intention to merge.
The companies have signed a definitive agreement, dated December 31, 2002,
calling for Old Florida to acquire the outstanding shares of Marine in the
merger. Under the terms of the definitive agreement, Marine shareholders would
receive .62 of a share of Old Florida common stock for each share of Marine
common stock, and Marine's subsidiary, Marine National Bank, would be merged
into Old Florida's subsidiary bank, Old Florida Bank.

Marine had assets of approximately $65 million at September 30, 2002. At
September 30, 2002, the two institutions, on a pro forma basis, had combined
total assets of approximately $171 million and four branches in Collier and Lee
Counties, Florida.

Larry Johnson, President and Chief Executive Officer of Old Florida, stated,
"The merger with Marine expands Old Florida into the attractive market of Naples
while, at the same time, achieving significant revenue enhancements and cost
savings in order to provide long term value to shareholders. We are very excited
about the prospects of sharing and expanding our Old Florida philosophy of
community banking in Naples. We are committed to providing the same level of
high quality products and services to all Marine customers while preserving the
inherent goodwill associated with community banking."

Pierce T. Neese, Chairman of Marine, stated, "We are delighted to have reached
this agreement to merge with Old Florida. Both organizations share the same
dedication to customer service, and I am very pleased that a strong community
bank will continue to serve the needs of our Naples market."

The transaction is structured as a tax-free exchange. The merger, which is
expected to be completed in the second quarter of 2003, is subject to approval
by the shareholders of Marine and regulatory authorities, among other things.
