             TEREX PROVIDES FIRST QUARTER 2005 PRELIMINARY RESULTS;
             FILES FORM 12B-25 REGARDING ITS FIRST QUARTER FORM 10-Q

     WESTPORT, CT, May 10, 2005 -- Terex Corporation (NYSE: TEX) today announced
it expects  total  revenues  for the  quarter  ended March 31, 2005 to be in the
range of $1.40-$1.45  billion,  an increase of over 35% versus the first quarter
of 2004.  Additionally,  at this time, Terex  anticipates fully diluted earnings
per share,  before special items,  for the quarter ended March 31, 2005 to be in
the  range  of  $0.50 to  $0.55.  Net debt  (total  debt  less  cash)  increased
approximately  $100 million in the first quarter of 2005,  slightly  better than
Terex's previous guidance of $125 million.  The increase in the outstanding debt
balances  reflects  an  investment  in working  capital in  anticipation  of the
seasonally strong second quarter selling activities. Terex will be releasing its
first quarter 2005 financial  results before the end of May 2005, and intends on
hosting a  conference  call to  review  its first  quarter  performance  shortly
thereafter.  No  update  on  earnings  guidance  will be  provided  prior to the
publication of the first quarter 2005 financial results.

     Terex also announced today that it has filed a Form 12b-25  Notification of
Late Filing with the Securities and Exchange Commission,  notifying the SEC that
the Company is delaying  the filing of its Form 10-Q for the period  ended March
31, 2005. As previously announced, Terex has not yet finalized its third quarter
2004 and full year 2004 results  pending  completion  of its  detailed  internal
accounting review, the restatement of Terex's financial statements for the years
ended December 31, 2000,  2001, 2002 and 2003, and the completion of its audited
financial  statements for 2004. Terex will delay the filing of its Form 10-Q for
the first quarter of 2005 until it completes this review,  restatement and audit
for the earlier periods and files the  appropriate  documents with the SEC. This
delay in filing the Form 10-Q for the first  quarter of 2005 will extend  beyond
the due date for the Form 10-Q,  including the five-day extension period.  Terex
continues to work diligently to complete its  restatement,  audit and assessment
of internal control over financial reporting.  Terex believes that it is nearing
completion of this process,  and currently  anticipates  filing all  appropriate
documents,  including applicable financial statements,  with the SEC in the near
future.
