    Statement Under Oath of Principal Executive Officer Regarding Facts and
                 Circumstances Relating to Exchange Act Filings

I,   Ronald M. DeFeo, Chairman, President and Chief Executive Officer of Terex
Corporation, state and attest that:

     (1) To the best of my knowledge, based upon a review of the covered reports
     of Terex  Corporation,  and,  except  as  corrected  or  supplemented  in a
     subsequent covered report:

     o    no covered report  contained an untrue statement of a material fact as
          of the end of the period  covered by such  report (or in the case of a
          report on Form 8-K or definitive  proxy  materials,  as of the date on
          which it was filed); and

     o    no covered  report  omitted to state a material fact necessary to make
          the statements in the covered  report,  in light of the  circumstances
          under which they were made, not misleading as of the end of the period
          covered  by such  report  (or in the case of a  report  on Form 8-K or
          definitive proxy materials, as of the date on which it was filed).

     (2) I have reviewed the contents of this statement with the Company's audit
     committee.

     (3) In this statement  under oath,  each of the  following,  if filed on or
     before the date of this statement, is a "covered report":

     o    the Terex  Corporation  Annual  Report on Form 10-K for the year ended
          December 31, 2001;

     o    all reports on Form 10-Q,  all reports on Form 8-K and all  definitive
          proxy  materials  of  Terex  Corporation  filed  with  the  Commission
          subsequent to the filing of the Form 10-K identified above; and

     o    any amendments to any of the foregoing.


                                        Subscribed and sworn to
/s/ Ronald M. DeFeo                     before me this 9th day of
