share (the "FBS Common Stock"), and (ii) each outstanding share of USBC 8 1/8%
Cumulative Preferred Stock, liquidation preference $25 per share, would be
converted into one share of new preferred stock of FBS with substantially
identical terms.  Pursuant to the Merger Agreement, FBS has agreed to change its
name to U.S. Bancorp as of the effective time of the Merger.

     John F. Grundhofer will continue as President and Chief Executive Officer
of the combined company.  Gerry B. Cameron, Chairman and Chief Executive Officer
of USBC, will become Chairman of the combined company for a term extending
through December 31, 1998.  The combined company will continue to be
headquartered in Minneapolis, Minnesota.
