NEW YORK (AS SUCCESSOR TRUSTEE TO UNITED STATES TRUST COMPANY OF NEW YORK), a
New York corporation, as trustee (the "Trustee").

                  WHEREAS, the Company, and the Subsidiary Guarantors (as
defined therein) and the Trustee are parties to an Indenture, dated as of March
29, 2001, as amended by First Supplemental Indenture dated as of October 1,
2001, and as further amended by Second Supplemental Indenture as of September
30, 2002 (said Indenture, as it may heretofore or hereafter from time to time be
amended, the "Indenture") providing for the issuance of the Company's 10-3/8%
Senior Subordinated Notes due 2011 (the "Notes");

                  WHEREAS, the Company has acquired all of the outstanding
capital stock of Terex Financial Services, Inc., Commercial Body Corporation and
Combatel Distribution, Inc. (collectively referred to as the "New Guarantors"
and individually as a "New Guarantor");

                  WHEREAS, pursuant to the terms of the Indenture, the New
Guarantors have become Restricted Subsidiaries organized under the laws of the
United States and, as such, the Company is required to cause the New Guarantors
to execute and deliver a supplemental indenture and the Subsidiary Guarantee
endorsed on the Notes; and

                  WHEREAS, the Company, the Subsidiary Guarantors and the
Trustee desire to amend the Indenture to add the New Guarantors as a Subsidiary
Guarantor under the Indenture.

                  NOW, THEREFORE, the Company, the Subsidiary Guarantors, the
New Guarantors and the Trustee agree as follows for the equal and ratable
benefit of the Holders of the Notes.

                                    ARTICLE 1

                           AMENDMENT TO THE INDENTURE

         Section 1.01. Each New Guarantor shall hereby become a Subsidiary
Guarantor under the Indenture effective as of the date hereof, and as such shall
be entitled to all the benefits and be subject to all the obligations, of a
Subsidiary Guarantor thereunder. Each New Guarantor agrees to be bound by all
those provisions of the Indenture binding upon a Subsidiary Guarantor.

                                    ARTICLE 2

                                  MISCELLANEOUS

         Section 2.01. The supplement to the Indenture effected hereby shall be
binding upon all Holders of the Notes, their transferees and assigns. All Notes
issued and outstanding on the date hereof shall be deemed to incorporate by
reference or include the supplement to the Indenture effected hereby.



         Section 2.02. All terms used in this Supplemental Indenture which are
defined in the Indenture shall have the meanings specified in the Indenture,
unless the context of this Third Supplemental Indenture otherwise requires.

         Section 2.03. This Supplemental Indenture shall become a binding
agreement between the parties when counterparts hereof shall have been executed
and delivered by each of the parties hereto.

         Section 2.04. This Supplemental Indenture shall be construed,
interpreted and the rights of the parties determined in accordance with the laws
of the State of New York, as applied to contracts made and performed within the
State of New York, without regard to principles of conflicts of law.

         Section 2.05. This Supplemental Indenture may be executed in several
counterparts, each of which shall be an original and all of which shall
constitute but one and the same amendment.

         Section 2.06. The recitals contained in this Supplemental Indenture are
made by the Company and not by the Trustee and all of the provisions contained
in the Indenture, in respect of the rights, privileges, immunities, powers and
duties of the Trustee shall be applicable in respect thereof as fully and with
like effect as if set forth herein in full.

         IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed as of the date first above written.
