Report of Independent Registered Public Accounting Firm


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


We have audited the accompanying Statements of Net Assets Available for Benefits of the Terex Corporation and Affiliates’ 401(k) Retirement Savings Plan (the “Plan”), as of December 31, 2010 and 2009, and the related Statement of Changes in Net Assets Available for Benefits for the year ended December 31, 2010.  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 in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards 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.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the Net Assets Available for Benefits of the Plan, as of December 31, 2010 and 2009, and the Changes in Net Assets Available for Benefits for the year ended December 31, 2010, in conformity with U.S. Generally Accepted Accounting Principles.

Our audits were conducted for the purpose of forming an opinion on the basic 2010 financial statements taken as a whole. The supplemental Schedule H, Line 4i – Schedule of Assets (Held at End of Year) 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 Savings 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 (the “Company”) meeting minimum eligibility requirements. The investments of the Plan are held in a trust account by Fidelity Management Trust Company (“Fidelity”), the trustee of the Plan.

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

A committee, consisting of at least three members appointed by the Company's Board of Directors, administers the benefit structure of the Plan ("Administrative Committee"). The Administrative Committee is considered the plan administrator for purposes of ERISA.

The Plan permits participants to irrevocably designate some or all of their elective contributions under the Plan as designated Roth contributions. Designated Roth contributions are elective contributions that, unlike pre-tax elective contributions, are currently includible in the participant's gross income. The Roth contributions are made in lieu of all or a portion of the elective contribution the participant is otherwise eligible to make under the Plan.

In July 2009, the Plan was amended to allow each participating employer to make profit sharing contributions as applicable to its employees which may differ between participating employers. The definition of employee was amended to include as eligible employees, individuals providing service for more than 180 days from their employment commencement date.

In December 2009, the Plan was timely amended to comply with provisions of the Pension Protection Act of 2006, Worker, Retiree and Employer Recovery Act and certain other provisions of applicable law that were effective after December 31, 2006.

During 2009, Terex Cranes Wilmington, Inc. and Koehring Cranes, Inc. were merged into Terex USA, LLC. Provisions specific to the employees under these former entities were maintained under the new entity.

On February 19, 2010, the Company sold its mining business and as a result, the participating employers related to the mining business, which included Terex Reedrill (“Reedrill”) and Halco America Inc. (“Halco”), are no longer participating employers in the Plan. The Company has determined that this transaction did not result in a partial plan termination.

In December 2010, the Plan was amended to change the maximum amount of the Company's matching contribution to 5% of the participants compensation effective January 1, 2011, except for certain participants of Powerscreen USA, LLC d/b/a Simplicity Engineering, Inc. (“Simplicity”) and of Terex USA, LLC, who are subject to collective bargaining agreements ("Represented"). The Plan was amended to change the Company matching contribution for Simplicity Represented participants to 100% of the first 3% of a participant's contribution to the Plan effective January 1, 2011. The Plan was amended to change the Company matching contribution for certain Represented Terex USA, LLC participants to 100% of the first 5% of a participant's contribution to the Plan effective March 6, 2011. The Plan was amended to change a participating employer name from Powerscreen USA, LLC d/b/a Simplicity Engineering, Inc. to Simplicity Engineering, Inc. The amendment also added a section regarding Roth conversions for all Plan participants.

Participant Eligibility - Permanent employees may begin participation on the first day of the month following their hiring, with the exception of Simplicity Represented employees, who are eligible to participate in the Plan after 120 days of service. Represented employees of Reedrill and Halco were eligible after completion of six months of service.
    
Contributions - Participants may contribute a maximum of 80% of their compensation to the Plan in any combination of pre-tax, Roth or post-tax contributions. The maximum pre-tax contribution permitted under Internal Revenue Service (“IRS”) regulations in 2010 was $16,500. Participants age 50 and older can elect to make additional pre-tax and Roth contributions (“catch-up contributions”) up to the limits prescribed by IRS regulations. These additional catch-up contributions are not eligible for matching Company contributions.

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

NOTES TO FINANCIAL STATEMENTS


The Company provides safe harbor matching contributions of 100% of the first 4% (5% after December 31, 2010) of the participant's contributions, except for certain Represented participants of Simplicity and Terex USA, LLC. For Simplicity Represented participants, the Company contributions are 50% of the first 4% of a participant's contribution to the Plan (effective January 1, 2011, 100% of the first 3% of a Simplicity participants' contribution to the Plan). For certain Terex USA, LLC Represented participants, the Company contributions are 100% of the first 4% (5% after March 6, 2011) of the participant's contributions. For Represented employees of Reedrill and Halco, the Company matched 33.33% of the first 6% of the participant's contribution.

The Company may make, in its sole discretion, supplementary contributions.

Company contributions were made exclusively in Terex Corporation common stock, $.01 par value per share (“Common Stock”) through August 31, 2010. Company matching contributions in Common Stock are unrestricted, thereby allowing participants to exchange the value of Common Stock into other investment options. As of September 1, 2010, participants were given the option of directing their Company matching contributions based on their participant contribution elections.

Contributions (excluding catch-up contributions) are limited in that the sum of: a) total Company contributions; b) total participant pre-tax contributions; c) total participant Roth contributions and d) total participant post-tax contributions, cannot exceed the lesser of: i) $49,000 or ii) 100% of the participant's total compensation for the year. Participants are able to direct current contributions and redistribute accumulated contributions and earnings between investment alternatives.

All employees under the Plan are subject to automatic enrollment of 2% of compensation, except for certain Represented employees in Terex USA, LLC. Effective August 1, 2011, certain Represented employees of Terex USA, LLC are also subject to automatic enrollment of 2% of compensation.

Vesting - Participants are fully vested immediately in their voluntary contributions and all Company safe harbor matching contributions, plus any actual earnings thereon, except for Represented employees of Reedrill and Halco, who vested in all Company contributions after one year of eligible service.

Forfeitures - Nonvested (prior to safe harbor matching provisions) Company contributions of participants that have separated from the Company become forfeitures and are held in a separate account and may be used to reduce future Company contributions or to pay the Plan's administrative fees. However, participants that return to service within five years from their separation date will be entitled to continue vesting in the Company contributions which were previously forfeited. At December 31, 2010 and 2009, respectively, forfeited nonvested accounts totaled $125,589 and $170,018. These accounts will be used to offset future Company contributions or pay the Plan's administrative fees. During the year ended December 31, 2010, $77,586 of the forfeiture account was used to offset Company contributions or for payment of the Plan's expenses.

Allocation of Earnings - Each participant's account is credited with contributions and an allocation of earnings (losses) from the respective investment funds. A participant's contributions and related Company's contributions are used to purchase shares in the various investment alternatives. 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 the participant can elect to keep the investments in the Plan. Withdrawals are also permitted for financial hardship, rollover and after-tax contributions, as defined in the Plan document, or upon attainment of age 59-1/2.

In the event the participant does not direct the distribution, the Administrative Committee is allowed to designate an individual retirement plan for a mandatory distribution greater than $1,000.

Notes Receivable from Participants - Participants may obtain loans between $1,000 and 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. As of December 31, 2010, interest

401(k) RETIREMENT SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

rates on participant loans ranged from 4.25% to 10.50% with maturities at various dates through 2026.

Participant-Directed Investments - As of September 1, 2010, the Company matching contributions became participant-directed and, therefore, all assets of the Plan became participant-directed investments. Participants have the option of directing their account balance to one or more different investment options. The investment options include various mutual funds, a common collective trust and Company common stock. Prior to September 1, 2010, the Company matching contribution was not participant-directed.

2.
SIGNIFICANT ACCOUNTING POLICIES

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

Expenses - Fees and expenses related to administering the Plan are generally paid by the Company. Investment management fees and loan administration fees are paid by participants.

Payment of Benefits - Benefits are recorded when paid.

Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of investment income and expenses during the reporting period. Actual results could differ significantly from those estimates.

Investment Valuation and Income Recognition - The Plan's investments are stated at fair value (see Note 3). Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Net appreciation in the aggregate fair value of investments is comprised of all realized and unrealized gains and losses during the year. Dividends are recorded on the ex-dividend date.

Investment contracts held by a defined contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The Plan invests in investment contracts through a common collective trust. The Statement of Net Assets Available for Benefits presents the fair value of the investment in the collective trust as well as the adjustment of the investment in the collective trust from fair value to contract value relating to the investment contracts. The Statement of Changes in Net Assets Available for Benefits has been prepared using the contract value of fully benefit-responsive investment contracts.

Notes Receivable from Participants - Notes receivable from participants are valued at unpaid principal balance plus accrued interest, which approximates fair value. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document.

Recent Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2010-06, “Improving Disclosures about Fair Value Measurements,” which amends Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”). This amendment requires new disclosures, including the reasons for and amounts of significant transfers in and out of Levels 1 and 2 fair value measurements and separate presentation of purchases, sales, issuances, and settlements in the reconciliation of activity for Level 3 fair value measurements. It also clarified guidance related to determining the appropriate classes of assets and liabilities and the information to be provided for valuation techniques used to measure fair value. This guidance is effective for reporting periods beginning after December 15, 2009, except for the Level 3 disclosure requirements, which will be effective for fiscal years beginning after December 15, 2010, and interim periods within those fiscal years. The Plan is evaluating the impact of the provisions of ASU 2010-06 that are not yet effective, but does not expect that it will have a significant impact on the determination or reporting of its financial results.


7

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

NOTES TO FINANCIAL STATEMENTS

In September 2010, the FASB issued ASU 2010-25, “Reporting Loans to Participants by Defined Contribution Pension Plans,” which amends ASC 962, "Plan Accounting - Defined Contribution Pension Plans." This guidance clarifies how loans to participants should be classified and measured by defined contribution pension plans. Participant loans are required to be classified as notes receivable from participants, which are segregated from plan investments and measured at their unpaid principal balance plus any accrued but unpaid interest. ASU 2010-25 is effective for periods ending after December 15, 2010, and requires retrospective application to all periods presented. The Plan adopted ASU 2010-25 in its Statement of Net Assets Available for Benefits as of December 31, 2010, and applied it retrospectively to December 31, 2009. The adoption of this guidance did not have a significant impact on the financial results of the Plan.

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends ASC 820. The amendment is the result of work by the FASB and the International Accounting Standards Board to develop common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles and International Financial Reporting Standards. The amendment clarifies that the concepts of highest and best use in a fair value measurement are relevant only when measuring the fair value of nonfinancial assets and are not relevant when measuring the fair value of financial assets or liabilities. The guidance expanded the disclosures for fair value measurements categorized within Level 3 of the fair value hierarchy to include the valuation processes used by the reporting entity and the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs, if any. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. The Plan is evaluating the adoption of ASU 2011-04, but does not expect that it will have a significant impact on the determination or reporting of its financial results.

3.
FAIR VALUE MEASUREMENT

The Plan performs fair value measurements in accordance with ASC 820. ASC 820 defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Plan considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

ASC 820 also establishes a fair value hierarchy that requires the Plan to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Determining which category an asset or liability falls within this hierarchy requires judgment. ASC 820 establishes three levels of inputs that may be used to measure fair value:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 - Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
The Plan's valuation methodology used to measure the fair value of common stock and mutual funds were derived from quoted market prices as all of these instruments have active markets. The Common Collective Trust value is determined by the contractual terms of the underlying guaranteed investment contracts (“GICs”) and is priced based on the market value of the underlying investments in the portfolio which may include U.S. Treasury bonds, corporate bonds, mortgage-backed securities, asset-backed securities, and derivative instruments, including futures, options, and swaps.

The Plan has an interest in Fidelity Managed Income Portfolio Class I (“MIP”), a common collective trust. The majority of this MIP is invested in synthetic GICs which are fully benefit-responsive. A synthetic GIC is comprised of two components, an underlying asset and a “wrapper” contract. Wrapper contracts generally change the investment characteristics of underlying securities (such as corporate debt or U.S. Government securities) to those of guaranteed investment contracts. As described in Note 2, Significant Accounting Policies - Investment Valuation and Income Recognition, contract value is the relevant measurement attribute for synthetic GICs. Contract value, as reported to the Plan, represents the principal balances of the contracts, plus accrued interest at the stated rate, less payments received and contract charges by the insurance company. There is no immediate recognition of investment gains and losses. Instead, the gain or loss is recognized over time by adjusting the interest rate credited to the MIP under the wrapper contract. The wrapper contract also provides for the payment of participant withdrawals and exchanges at contract value. The contract value as of December 31, 2010 and 2009, was $14,502,627 and $16,528,642 respectively; the fair value, as of December 31, 2010 and 2009, was $14,621,514 and $16,226,900, respectively.

Wrapper contracts accrue interest using a formula called the “crediting rate.” The crediting rate is the discount rate that equates estimated future market value with the portfolio's contract value. The crediting rate is based on a formula agreed upon with the issuer of the wrapper contract with the requirement that interest rates may not be less than zero percent. Such interest rates are reviewed on a quarterly basis for resetting. The crediting rate may be affected by many factors, including purchases and redemptions by unitholders. Certain events limit the ability of the Plan to transact at contract value with the wrapper contract issuer. Such events include the following: (1) the failure of the Plan to qualify under Section 401(a) or Section 401(k) of the Internal Revenue Code, (2) establishment of a defined contribution plan that competes with the Plan for employee contributions, (3) any substantive modification to the Plan or administration of the Plan that is not consented to by the wrapper contract issuer, and (4) transfer of assets from the fund directly to a competing option. However, the Plan's management is not aware of the occurrence or likely occurrence of any such events, which would limit the Plan's ability to transact at contract value with participants. The wrapper contract issuer may terminate a wrapper contract for cause at any time.

The average yields earned by contracts held by the MIP were approximately 2.68% and 3.16% for the years ended December 31, 2010 and 2009, respectively. The average yields earned by the Plan for contracts held by the MIP based on the actual interest rates credited to participants were approximately 1.44% and 1.20% for the years ended December 31, 2010 and 2009, respectively.

RISKS AND UNCERTAINTIES

The Plan provides for various investment options in investment securities. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.

For details on risks facing the Company, see Item 1A in the Company's Annual Report on Form 10-K for the year ended December 31, 2010.

7.
CONTINGENCIES

During the first quarter of 2010, four putative class action lawsuits that generally cover the period between December 31, 2007 and February 2009, were filed in the United States District Court, District of Connecticut. The actions were consolidated by the court and the Company has received a consolidated complaint which was filed in the United States District Court, District of Connecticut on September 20, 2010, and is entitled In Re Terex Corp. ERISA Litigation. The complaint asserts claims under ERISA against the Company, the Plan's Administrative Committee, the Company's Board of Directors, and certain other individuals alleged to have fiduciary responsibility. These complaints, purportedly brought on behalf of all participants in the Plan and on behalf of the Plan, allege, among other things, that there were breaches

11

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

NOTES TO FINANCIAL STATEMENTS

of fiduciary duty related to investments in the Company's stock. The complaints all seek unspecified compensatory damages, costs and expenses from the Company and the named individuals. The lawsuit is at the very early stages. The Company and the named individuals believe that they have acted, and continue to act, in compliance with ERISA, and that the allegations are without merit. The Company and the named individuals will continue to vigorously defend against the action. Accordingly, on November 19, 2010, the Company filed a motion to dismiss the lawsuit. This motion is currently pending before the court.

For further details on these lawsuits, see Note R in the Company's Annual Report on Form 10-K for the year ended December 31, 2010.

8.
PARTY-IN-INTEREST

Certain Plan investments are shares of mutual funds managed by Fidelity. In addition to serving as trustee, Fidelity also serves as custodian and, therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan to Fidelity for the investment management services and loan administration were $148,237 for the year ended December 31, 2010. Fees paid for legal services were $24,307 for the year ended December 31, 2010. In addition, transactions in Common Stock and Notes receivable from participants qualify as party-in-interest transactions.

9.
INCOME TAX STATUS
The Plan received a determination letter, dated April 10, 2009, in which the IRS stated that the Plan met the qualification requirements of Sections 401(c) and 401(k) of the Internal Revenue Code and that the Plan is exempt from Federal income taxation. The Plan has been amended subsequent to receiving the determination letter. The plan administrator believes that the Plan is designed and is being operated in compliance with the applicable requirements of the IRS.
U.S. generally accepted accounting principles require Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The Plan administrator has analyzed the tax positions taken by the plan, and has concluded that as of December 31, 2010, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2007.

10.
TERMINATION OF THE PLAN

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. 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 trustee. In the event of Plan termination, Represented participants would become 100 percent vested in their Company contributions.

11.
