State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR,
or the transition report or portion thereof, could not be filed within the
prescribed time period.

As previously disclosed in Current Reports on Form 8-K furnished to the
Securities and Exchange Commission on October 27, 2004, November 10, 2004,
January 13, 2005 and March 4, 2005, Terex Corporation ("Terex" or the "Company")
has commenced a detailed examination of its intercompany transactions in an
effort to reconcile imbalances in certain of the Company's accounts. Based on
the results of its review, the Company concluded that the financial statements
of Terex for the years ended December 31, 2000, 2001, 2002 and 2003 need to be
restated to correct certain errors. The Company's internal review activities
have not yet been completed and the Company is currently working to complete its
financial statements for the year ended December 31, 2004. In addition, the
Company has not yet completed its assessment of effectiveness of internal
control over financial reporting as of December 31, 2004. Once the Company's
Annual Report on Form 10-K for the year ended December 31, 2004 and its
Quarterly Report on Form 10-Q for the period ended September 30, 2004 are filed,
the Company will file its Quarterly Report for the quarter ended March 31, 2005,
as soon thereafter as possible. The Company also will be filing a further
Current Report on Form 8-K shortly with an additional discussion on the status
of these matters.
