Item 1.01.  Entry into a Material Definitive Agreement.

         In compliance with a Frequently Asked Questions Bulletin on Form 8-K
issued on November 23, 2004 by the Division of Corporate Finance of the
Securities and Exchange Commission ("SEC"), Terex Corporation ("Terex" or the
"Company") is disclosing the following items which the SEC may deem to be
material definitive agreements.

         The Board and the stockholders of Terex previously adopted the Terex
Corporation 2004 Annual Incentive Compensation Plan (the "Annual Plan"), which
provides for incentive compensation in the form of an annual bonus to key
executives of Terex upon satisfaction of certain performance measures. Terex has
previously filed the Annual Plan with the SEC as an exhibit to its Form 10-Q for
the quarter ended March 31, 2004. In 2004, the Board approved the performance
targets to be applied under the Annual Plan for determining bonuses for all
Annual Plan participants with respect to the Company's 2004 fiscal year.

         A summary of the material terms of the performance targets to be
applied under the Annual Plan for determining bonuses for Annual Plan
participants (other than Terex's Chief Executive Officer) with respect to the
Company's 2004 fiscal year is filed as Exhibit 10.1 to this Form 8-K. A summary
of the material terms of the performance targets to be applied under the Annual
Plan for determining the bonus for Ronald M. DeFeo, the Company's Chief
Executive Officer, with respect to the Company's 2004 fiscal year is filed as
Exhibit 10.2 to this Form 8-K. The material terms of the performance targets to
be applied under the Annual Plan for determining bonuses for all Annual Plan
participants with respect to the Company's 2005 fiscal year were previously
filed with the SEC on Forms 8-K on January 6, 2005 and April 6, 2005.

         Bonuses for the Company's 2004 fiscal year were delayed in being paid
to the Company's named executive officers (as defined in the regulations to the
Securities and Exchange Act of 1934) pending the completion of the Company's
financial restatement process. On October 6, 2005, a partial bonus for the
Company's 2004 fiscal year was paid to one of the named executive officers of
the Company consistent with the performance targets described in Exhibit 10.1.
It is anticipated that bonuses for the Company's 2004 fiscal year will be paid
to the other named executive officers in the future. When such bonuses are paid,
the payments will be consistent with the performance targets described in
Exhibits 10.1 and 10.2, as applicable.
