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 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, although, as previously disclosed in Current Reports on Form
8-K, the Company has determined that a material weakness existed in the
Company's internal control over financial reporting which contributed to the
occurrence of these errors. The Company believes that it is nearing completion
of this process, and currently anticipates filing all appropriate documents,
including applicable financial statements, for the year ended December 31, 2004
and prior periods with the SEC in the near future. Once these reports are filed,
the Company will file its Quarterly Reports for the quarters ended March 31,
2005 and June 30, 2005 as soon thereafter as possible.

quarter ended June 30, 2005 to be $1.54, as compared to $1.17 for the fiscal
quarter ended June 30, 2004.
