Item 1.01.  Entry into a Material Definitive Agreement.

         Terex Corporation ("Terex" or the "Company") and Colin Robertson, the
newly appointed Executive Vice President, Operations of Terex, have entered into
an Offer Letter dated as of January 5, 2006 (the "Robertson Letter"). A copy of
the Robertson Letter is filed as Exhibit 10.1 to this Form 8-K. The following

         Pursuant to the Robertson Letter, Mr. Robertson's employment with Terex
as Executive Vice President, Operations, reporting to Ronald M. DeFeo, the
Chairman, President and Chief Executive Officer of Terex, is strictly at will.
However, termination of employment by Mr. Robertson is subject to twelve (12)
months written notice from him to the Company.

         Under the Robertson Letter, Mr. Robertson is to receive an initial
annual base salary of $525,000, subject to review periodically by the

long-term incentive compensation in accordance with any plan or plans
established by the Company. Mr. Robertson will continue to be eligible to
participate in the Terex Supplemental Executive Retirement Plan and will receive
additional benefits, including reimbursement of certain relocation expenses and
a company car.

         As soon as practicable and to the extent permitted by law, Mr.
Robertson will receive a grant of 10,000 shares of Terex common stock as well as
an option to purchase 5,000 shares of Terex common stock at the closing price of
a share of Terex common stock on the trading day immediately preceding the date
of the award. All shares and options will typically vest ratably over a
four-year period.

         If Terex appoints a new Chief Operating Officer of the Company, other
than Mr. Robertson, on or before December 31, 2008, then under certain
circumstances Mr. Robertson will be entitled to receive a severance benefit
equal to his annual base salary.

         The Robertson Letter requires Mr. Robertson to keep certain information
of the Company confidential during his employment and thereafter. The Robertson
Letter also contains an agreement by Mr. Robertson not to compete with the
business of the Company during his term of employment with the Company and for a
period of twelve (12) months thereafter. In addition, Mr. Robertson agrees that
he will not at any time during the period of his employment with the Company and
for a period of eighteen (18) months thereafter, directly or indirectly, engage
in any business or own or control any interest in, or act as a director,
officer, employee, agent or consultant of certain specified competitors of the
Company.
