To the Participants and Administrative Committee of the
Terex Corporation and Affiliates'
401(k) Retirement Savings Plan


In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of the Terex  Corporation and Affiliates'  401(k)  Retirement  Savings Plan (the
"Plan") at December 31, 2002 and 2001,  and the changes in net assets  available
for benefits for the year ended December 31, 2002, in conformity with accounting
principles  generally accepted in the United States of America.  These financial
statements are the responsibility of the Plan's  management;  our responsibility
is to express an opinion on these financial  statements based on our audits.  We
conducted our audits of these  statements in accordance with auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements taken as a whole.  The supplemental  schedule of nonexempt
transactions  is presented for the purpose of  additional  analysis and is not a
required part of the basic financial statements but is supplementary information
required by the  Department of Labor's Rules and  Regulations  for Reporting and
Disclosure  under the Employee  Retirement  Income  Security  Act of 1974.  This
supplemental  schedule  is the  responsibility  of the  Plan's  management.  The
supplemental  schedule has been subjected to the auditing  procedures applied in
the audits of the basic  financial  statements  and, in our  opinion,  is fairly
stated in all material  respects in relation to the basic  financial  statements
taken as a whole.

TEREX CORPORATION AND AFFILIATES'
401(k) RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------


1.   DESCRIPTION OF THE PLAN

     The following  description of the Terex Corporation and Affiliates'  401(k)
     Retirement  Saving Plan (the "Plan")  provides  only  general  information.
     Participants  should  refer  to  the  Plan  document  for a  more  complete
     description of the Plan's provisions.

     General  - The Plan is a defined  contribution  plan  that  covers  certain
     salaried and hourly  employees of Terex  Corporation  and its  subsidiaries
     ("Terex"  or  the  "Company")  meeting  minimum  eligibility  requirements.
     Certain  officers of Terex serve as trustees of the Plan (the  "Trustees").
     The investments of the Plan are held by Fidelity  Management  Trust Company
     ("Fidelity")   and    Massachusetts    Mutual   Life   Insurance    Company
     ("MassMutual").

     The Plan is subject to the  provisions  of the Employee  Retirement  Income
     Security Act of 1974 ("ERISA").

     An Administrative Committee, consisting of at least three members appointed
     by the Company's Board of Directors,  administers the benefit  structure of
     the Plan. The Company is considered the Plan  Administrator for purposes of
     ERISA.

     On  October  1,  2001,  the  Company   completed  the  acquisition  of  CMI
     Corporation  and  its  affiliates  ("CMI").  The  employees  of CMI  became
     eligible for  participation in the Plan effective  October 1, 2002.  Assets
     valued  at  $14,222,443  were  transferred  into  the  Plan  from  the  CMI
     Corporation 401(k) Plan in October 2002.

     On January 15,  2002,  the Company  completed  the  acquisition  of Utility
     Equipment,  Inc.,  which does  business as Pacific  Utility  Equipment  Co.
     ("Utility Equipment"). Effective December 1, 2002, the employees of Utility
     Equipment became eligible for  participation in the Plan.  Assets valued at
     $5,179,122 were transferred into the Plan from the Utility Equipment,  Inc.
     Employees Savings and Security Plan in December 2002.

     On April 11, 2002, the Company  acquired  certain assets and liabilities of
     Advance Mixer,  Inc.  ("Advance  Mixer") in the  bankruptcy  proceedings of
     Advance Mixer.  Effective  June 1, 2002,  employees of Advance Mixer became
     eligible for participation in the Plan.

     Effective  December 31, 2002, the Terex Corporation and Affiliates'  401(k)
     Retirement Savings Plan for Represented Employees (the "Union Plan") merged
     into the Plan.  Assets valued at $4,397,926 were  transferred into the Plan
     from the Union Plan on December  31, 2002.  Participants  of the Union Plan
     were the  hourly-rate  employees of the Company's PPM Cranes  ("PPM") Unit,
     Unit Rig  division  ("Unit  Rig"),  the  Terex  Parts  Distribution  Center
     ("Southaven"),   The  American  Crane   Corporation   ("American   Crane"),
     Cedarapids, Inc. ("Cedarapids"), and the former Bowerston Division of Simon
     Access ("Bowerston"), which was closed subsequent to the acquisition of the
     business on April 7, 1997.  Investments of the former  Bowerston  employees
     remain in the Plan;  however,  there are no additional employee or employer
     contributions being made. Terms for each subsidiary location are negotiated
     under separate collective  bargaining agreements and differ with respect to
     participant   eligibility,    participant    contributions   and   employer
     contributions.

     Participant  Eligibility  - Permanent  non-represented  employees may begin
     participation  on the  first  day  of the  month  following  their  hiring.
     Eligibility  for represented  employees is as follows:  Unit Rig after they
     complete  six  months  of  service;  Southaven  and  PPM  are  eligible  to
     participate  after  three  months  of  service;   and  American  Crane  and
     Cedarapids  are eligible to participate in the Plan on the first day of the
     month following their hiring.

     Participant  Contributions  - Participants  may contribute a maximum of 80%
     (20% prior to January  1,  2002) of their  compensation  to the Plan in any
     combination  of  pre-tax  or  post-tax   earnings.   The  maximum   pre-tax
     contribution  permitted under Internal Revenue Service ("IRS")  regulations
     in 2002  was  $11,000.  Participants  age 50 and  older  can  elect to make

TEREX CORPORATION AND AFFILIATES'
401(k) RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

     additional  pre-tax  contributions  ("catch-up  contributions")  up to  the
     limits   prescribed  by  IRS   regulations.   These   additional   catch-up
     contributions are not eligible for matching employer contributions.

     Employer  Contributions  - With  the  exception  of  employees  at CMI  and
     employees   represented  by  collective   bargaining   units,  the  Company
     contributes  50% of the first 8% of base  compensation  that a  participant
     contributes to the Plan. The Company  contributes  15% of the amount that a
     CMI employee contributes to the Plan, subject to IRS limits.

     For represented  employees,  the employer contributions are as follow: Unit
     Rig  provides  that Terex will match 50% of the first 6% of the  employee's
     salary that is contributed to the Plan;  Southaven provides that Terex will
     match 50% of the first 8% of the  employee's  salary that is contributed to
     the Plan;  PPM  provides  that  Terex will match 50% of the first 6% of the
     employee's salary that is contributed to the Plan;  American Crane provides
     that Terex will match 50% of the first 8% of the  employee's  contribution;
     and  Cedarapids  provides that Terex will match 100% of the first 4% of the
     employee's salary that is contributed to the Plan. The Company may make, in
     its sole discretion, supplementary contributions.

     All  Company  contributions  are  restricted  and are made in Terex  Common
     Stock.  However, each calendar year on the first business day of the second
     quarter,  all restricted  Company  matching  contributions  in Terex Common
     Stock will be reclassified to unrestricted,  thereby allowing  participants
     to exchange the value of Terex Common Stock into other investment  options.
     All Company  matching  contributions  posted  thereafter will once again be
     restricted  and invested in Terex Common  Stock until the  following  first
     business day of the second quarter.

     Contribution  Limits -  Contributions  are  limited  in that the sum of: a)
     total employer  contributions  and b) total employee pre-tax  contributions
     and c) total employee post-tax contributions,  cannot exceed the lesser of:
     i) $40,000 or ii) 100% (25% for years  prior to 2002) of the  participant's
     total  compensation  for the year.  Participants are able to direct current
     contributions  and  redistribute  accumulated  contributions  and  earnings
     between investment funds.

     Vesting -  Participants  are  immediately  fully vested in their  voluntary
     contributions  plus any actual earnings  thereon.  Participants vest in the
     employer contribution after one year of eligible service.

     Forfeitures  - Nonvested  employer  contributions  of  employees  that have
     separated  from the Company become  forfeitures  and are held in a separate
     account  and  shall  be  used  to  reduce  future  employer  contributions.
     Effective  January 1, 2002,  forfeitures can also be used to pay the Plan's
     administrative expenses.  However,  employees that return to service within
     five years from their  separation date will be entitled to continue vesting
     on the employer contributions which were previously forfeited.

     Allocation  of  Earnings  - Each  participant's  account is  credited  with
     contributions and an allocation of earnings from the respective  investment
     funds. A  participant's  contributions  are used to purchase  shares in the
     various  investment  funds.  The value of and the  earnings  credited  to a
     participant's account are based on the proportionate number of shares owned
     by the  participant  and the fair value of the  investment on the valuation
     date.

     Payment of  Benefits - Upon  retirement,  disability  or death,  the entire
     balance of the participant's  account becomes payable to the participant or
     designated  beneficiary.  Upon any other  termination  of  employment,  the
     participant receives the vested portion of his/her account; however, if the
     vested portion of the participant's  account is greater than $5,000 ($3,500
     prior to January 1, 2002) he/she can elect to keep the  investments  in the
     Plan.  Withdrawals are also permitted for financial hardship, as defined in
     the Plan, or upon attainment of age 59-1/2.

     Participant  Loans -  Participants  may obtain loans in an amount up to the
     lesser of $50,000 or 50% of the vested  portion of their  account  balance,
     subject to the  discretion  of the Plan  Administrator  and  certain  other
     restrictions. Terms of all loans are established by the Plan Administrator.

2.   SIGNIFICANT ACCOUNTING POLICIES

     Basis of  Accounting  - The  accompanying  financial  statements  have been
     prepared on the accrual basis.

     Investments - Plan  investments are stated at fair value based on published
     market prices or other independent sources. Net appreciation (depreciation)
     in  aggregate  fair value of  investments  is comprised of all realized and
     unrealized gains and losses during the year.

     Expenses  - Fees  and  expenses  related  to  administering  the  Plan  are
     generally paid by Terex.

     Withdrawals - Withdrawals are recognized at the time of distribution to the
     participant.

     Use of Estimates - The  preparation  of financial  statements in conformity
     with  accounting  principles  generally  accepted  in the United  States of
     America  requires  management to make estimates and assumptions that affect
     the reported amounts of assets and liabilities and disclosure of contingent
     assets and  liabilities  at the date of the  financial  statements  and the
     reported  amounts of revenues and  expenses  during the  reporting  period.
     Actual results could differ from those estimates.

3.   INVESTMENTS

     The following  presents the investments that represent 5 percent of more of
     the Plan's net assets:

         Retirement Savings Plan Master Trust          $70,707,321   $51,008,243


     During  2002  the  Plan's  investments   (including  gains  and  losses  on
     investments  bought and sold, as well as held during the year)  depreciated
     in value by $51,541 as follows:

      Mutual Funds                                     $    51,541


4.   INVESTMENT IN MASTER TRUST

     The Plan's assets are held in a trust account at Fidelity and consist of an
     interest in the Terex  Corporation  401(k)  Retirement  Savings Plan Master
     Trust (the "Master Trust").  The Master Trust was established to permit the
     commingling  of  the  trust  assets  for  similar  employee  benefit  plans
     sponsored  by the  Company.  At  December  31,  2002 and 2001,  the  Plan's
     interest in the net assets of the Master Trust was  approximately  100% and
     89.5%, respectively.

     Net  earnings of the Master Trust are  allocated  daily by Fidelity to each
     participant account balance. Net earnings include interest income, dividend
     income and net appreciation  (depreciation) of investments.  Contributions,
     benefit payments and expenses are made on a specific identification basis.

     The  Master  Trust  has  an  interest  in a  benefit-responsive  investment
     contract which is valued at contract value as determined by MassMutual, the
     holder of the  contract.  The contract  value at December 31, 2002 and 2001
     was $9,336,872 and $8,808,370,  respectively. The contract value represents
     contributions  made  under  contract,   plus  earnings,   less  participant
     withdrawals and administrative expenses. Participants may ordinarily direct
     the  withdrawal  or  transfer  of all or a  portion  of the  investment  at
     contract value. The guaranteed annual interest rate is 6 percent.

5.   NONPARTICIPANT-DIRECTED INVESTMENTS

     The  Company's  contributions  to the Plan  are  invested  solely  in Terex
     Corporation  Common  Stock.  Fidelity  holds all Terex  common stock in one
     investment  account and does not segregate  employer and employee purchased
     common stock activity.  As a result,  all Plan  investments in Terex common
     stock are  considered  nonparticipant-directed.  Information  about the net
     assets and the significant components of the changes in net assets relating
     to the nonparticipant-directed investments is as follows:

6.   PARTY-IN-INTEREST

     Certain  Plan and  Master  Trust  investments  are  shares of mutual  funds
     managed by Fidelity.  Fidelity also serves as a custodian  and,  therefore,
     these transactions qualify as party-in-interest  transactions. Fees paid by
     the Plan to Fidelity  for the  investment  management  services  amounts to
     $20,623 for the year ended December 31, 2002.

7.   INCOME TAX STATUS

     The Plan received a determination letter, dated April 21, 1998, that it met
     the  qualification  requirements  of  Sections  401(c)  and  401(k)  of the
     Internal  Revenue Code (the "IRC") and that the Plan is exempt from federal
     income  taxation.  Subsequently,  the  Plan  has  been  amended.  The  Plan
     Administrator believes that the Plan, as amended, continues to be qualified
     and exempt from tax under Sections 401(c) and 401(k) of the IRC.

     The Company filed for a new determination  letter on February 28, 2002. The
     IRS has acknowledged  receipt of the filing,  but has neither  commented on
     the request nor issued a determination letter.

8.   TERMINATION OF THE PLAN

     The Company believes that the Plan will continue  without  interruption but
     reserves  the  right to  discontinue  the  Plan.  In the  event  that  such
     discontinuance  results in the complete or partial termination of the Plan,
     the balance in each  participant's  account will be distributed as directed
     by the Trustees.

9.   NONEXEMPT TRANSACTION

     During 2002, the Company did not remit employee contributions timely in the
     case of one newly acquired  business unit. The Company has paid the related
     fines.  The  nonexempt  transaction  has no effect on the tax status of the
     Plan.

10.  SUBSEQUENT EVENTS

     On March 26, 2002,  the Company  acquired  EPAC  Holdings,  Inc.  which did
     business  under the names Telelect East and Eusco  ("Telelect  Southeast").
     Effective  April 1,  2003,  the  employees  of  Telelect  Southeast  became
     eligible for  participation  in the Plan.  Assets valued at $2,086,740 were
     transferred into the Plan on April 1, 2003.

     On September  18, 2002,  the Company  completed  the  acquisition  of Genie
     Holdings,  Inc. and its affiliates  ("Genie").  Effective February 1, 2003,
     the  employees of Genie  became  eligible  for  participation  in the Plan.
     Assets valued at $37,857,384  were transferred into the Plan on February 1,
     2003.
