Item 1.01.

Entry Into a Material Definitive Agreement.

On November 9, 2005, Marshall & Ilsley Corporation, a Wisconsin corporation (“M&I”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Gold Banc Corporation, Inc., a Kansas corporation (“Gold Banc”).  Subject to the terms and conditions of the Merger Agreement, Gold Banc will merge with and into M&I (the “Merger”), with M&I being the surviving corporation in the Merger.

Under the terms of the Merger Agreement, assuming that M&I common stock trades within a certain range as described in the Merger Agreement, each Gold Banc stockholder will receive $18.50 per share, consisting of $2.78 per share in cash and $15.72 in M&I common stock.  The total transaction value is approximately $700 million.

The boards of directors of M&I and Gold Banc have each approved the Merger Agreement.  The transactions contemplated by the Merger Agreement are subject to customary closing conditions, including regulatory approvals and approval of the Gold Banc stockholders, and are expected to be completed in the second quarter of 2006.

A copy of the Merger Agreement is attached hereto as Exhibit 10.1 and incorporated herein by reference.  The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement.

Concurrently with the execution of the Merger Agreement, M&I entered into a Stockholder Voting Agreement (the “Voting Agreement”) with Malcolm M. Aslin, Richard J. Tremblay, Donald C. McNeill, J. Gary Russ, Allen D. Petersen, William Randon, D. Patrick Curran, Daniel P. Connealy, Robert J. Gourley, and Jerry L. Neff (each, a “Stockholder,” and together, the “Stockholders”) pursuant to which each Stockholder has agreed to vote his shares of Gold Banc common stock in favor of the Merger Agreement and the transactions contemplated thereby, including the Merger.  The Stockholders individually own approximately 2.5% of the outstanding Gold Banc common stock.

A copy of the Voting Agreement is attached hereto as Exhibit 10.2 and incorporated herein by reference.  The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Voting Agreement.
