("Inland") merged with and into Mittal Steel Company N.V.'s wholly owned U.S. operating subsidiary Mittal Steel USA ISG Inc.

Copies of each of the Merger Agreement and the related press release, dated January 3, 2006, are filed herewith as Exhibit 99.1 and Exhibit 99.2, respectively, and are incorporated by reference herein in their entirety. The Merger Agreement provides that the surviving corporation will be named "Mittal Steel USA Inc."; incorporates the Certificate of Incorporation and By-laws for the surviving corporation; provides that the members of the Board of Directors and the officers of the surviving corporation will be the same as the current Board of Directors and officers of Mittal ISG; and sets forth the conversion of shares pursuant to the Merger. In connection with the Merger, Mittal ISG also succeeded to and assumed the obligations of Inland under Inland's existing contracts, including Inland's obligations under (i) the First Mortgage Indenture, dated April 1, 1928, between Inland and First Trust and Savings Bank and Melvin A.
