Introductory Note

     On November 9, 2005, Gold Banc Corporation, Inc., a Kansas corporation (the
"Company"), entered into an Agreement and Plan of Merger, as amended (the
"Merger Agreement"), with Marshall & Ilsley Corporation, a Wisconsin corporation
("M&I"), pursuant to which the Company merged with and into M&I, with M&I being
the surviving corporation (the "Merger"), effective 12:01 a.m. April 1, 2006. In
connection with the Merger, each outstanding share of the Company's common stock
was converted into the right to receive $2.78 per share in cash and .3576 of a
share of M&I common stock.

Item 1.02  Termination of a Material Definitive Agreement

     Effective April 1, 2006, in connection with the Merger, the Company
terminated a $25,000,000 line of credit pursuant to a Loan Agreement, dated as
of October 1, 2004, between the Company and JPMorgan Chase Bank, N.A. (as
successor by merger to Bank One, NA).

     In connection with the completion of the Merger, the Company requested the
