PART III -- NARRATIVE

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, Terex Corporation ("Terex" or the "Company")
has commenced a detailed examination 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 and for the quarters ended March 31, 2004
and June 30, 2004 need to be restated to correct certain errors. In addition,
Terex is also reviewing other historical accounting issues, including historical
revenue recognition practices, certain reserve balances and certain transactions
with United Rentals, Inc. 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, although, as previously disclosed
in Current Reports on Form 8-K, the Company has determined that material
weaknesses existed in the Company's internal control over financial reporting
which contributed to the occurrence of these errors. The Company anticipates
filing all appropriate documents, including applicable financial statements, for
the year ended December 31, 2004 and prior periods with the SEC as soon as
practicable. Once these reports are filed, the Company will file its Quarterly
Reports for the quarters ended March 31, 2005, June 30, 2005 and September 30,
2005 as soon thereafter as possible. The Company has received a waiver from its
bank lending group with respect to delivery of financial statements until
February 15, 2006.
