               WINTRUST FINANCIAL CORPORATION ANNOUNCES CLOSING OF
                ACQUISITION OF ADVANTAGE NATIONAL BANCORP, INC.
               ---------------------------------------------------

         LAKE FOREST, ILLINOIS - Wintrust Financial Corporation ("Wintrust")
(Nasdaq: WTFC) announced today the completion of its previously announced
acquisition of 100% of the ownership interest of Advantage National Bancorp,
Inc. ("Advantage") in a stock merger transaction. Advantage is the parent
company of Advantage National Bank that has locations in Elk Grove Village and
Roselle, Illinois.

         Advantage National Bank is a de novo bank that began operations in
January, 2001 and had total assets of approximately $107.5 million as of June
30, 2003. Advantage National Bank is being operated as a separately chartered
bank subsidiary of Wintrust. The merger allows Wintrust to expand into the
desirable northwest Chicago metropolitan area through a bank that has a
dedicated board of directors and management team and an operating culture that
has proven successful and is well positioned for future growth.

         Edward J. Wehmer, President and CEO of Wintrust, and Gary E. Umlauf,
Advantage's President and CEO, indicated "This transaction is a win-win
situation for both companies and more importantly for our customers. In both
firms, the clients' interests always come first and both organizations share a
common market philosophy of community banking. As we have worked together since
announcing the





transaction, we have become even more convinced about the excellent fit of this
merger for our two companies."

         Under the terms of the merger agreement, each share of Advantage common
stock outstanding was converted into the right to receive 0.757 shares of
Wintrust's common stock. The purchase price consists of approximately 670,900
shares of Wintrust's common stock to be issued in exchange for Advantage common
stock and $0.4 million of cash paid for outstanding Advantage warrants. The
shares issued in the transaction have been registered under the Securities Act
of 1933. Consummation of the transaction is not expected to have a material
impact on Wintrust's 2003 or 2004 earnings per share.
