Each of Bucyrus and its Subsidiaries has all requisite corporate or other power and authority to own its assets and to carry on its business as now being conducted and is duly qualified or licensed to do business and is in good standing in the jurisdictions in which the ownership of its property or the conduct of its business requires such qualification or license except where the failure to be so qualified or licensed would not reasonably be expected, individually or in the aggregate, to have a Bucyrus Material Adverse Effect. For purposes of this Agreement, the term “Bucyrus Material Adverse Effect” means any change, effect, occurrence, circumstance or development that has a material adverse effect on the business, properties, assets, results of operations or financial condition of Bucyrus and its Subsidiaries, taken as a whole, but shall exclude any effects resulting from or relating to (i) events affecting the United States, Canada, Europe, Asia, Australia or global economy or capital or financial markets generally; (ii) events that generally affect the industries in which Bucyrus and its Subsidiaries or their customers conduct business; (iii) changes in Law, U.S. GAAP, or in the authoritative interpretations thereof applicable to Bucyrus and its Subsidiaries; (iv) earthquakes or similar catastrophes, or acts of war (whether declared or undeclared), sabotage, terrorism, military action or any material escalation or worsening thereof; or (v) the execution, announcement or existence of this Agreement or the transactions contemplated hereby; provided, however, that in each case of (i), (ii), (iii) and (iv), in the event such change, effect, occurrence, state of facts, circumstance or development has, or would have reasonably be expected to have, a materially disproportionate adverse effect on Bucyrus and its Subsidiaries, relative to other Persons manufacturing and selling the same products made by Bucyrus and its Subsidiaries in the industries in which Bucyrus and its Subsidiaries operate then it shall be a Bucyrus Material Adverse Effect.

SECTION 2.2. Authorization; Enforceability.

(b) This Agreement constitutes, and the Stockholders Agreement when executed and delivered will constitute, a valid and binding obligation of Bucyrus, enforceable against Bucyrus in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar Laws affecting creditors’ rights generally or by general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or Law).

SECTION 2.3. Non-Contravention; Consents. (a) The execution, delivery and performance by Bucyrus of this Agreement and the Stockholders Agreement and the consummation of the transactions contemplated hereby and thereby, do not and will not (i) violate any provision of the certificate or articles of incorporation, bylaws or comparable organizational documents of Bucyrus or any Subsidiary thereof; (ii) conflict with, result in a breach of, constitute a default under, result in the termination, cancellation or acceleration with respect to, any term or provision of any contract, commitment, right or other obligation to which Bucyrus, its Subsidiaries or any of its Affiliates is a Party or is subject; or (iii) violate or result in a breach of or constitute a default under any Law or other restriction of any Governmental Authority to which Bucyrus or any Subsidiary thereof is subject, except with respect to clauses (ii) and (iii), for violations, breaches, conflicts, defaults, terminations, cancellations or accelerations as would not reasonably be expected, individually or in the aggregate, to have a Bucyrus Material Adverse Effect.

(b) The execution, delivery and performance of this Agreement and the Stockholders Agreement and the consummation of the transactions contemplated hereby do not require any consent, authorization or approval from any third party or any Governmental Authority on the part of Bucyrus or its Subsidiaries or Affiliates.

SECTION 2.4. Capitalization.

(a) As of December 31, 2009, the authorized capital stock of Bucyrus consisted of 200,000,000 shares of Bucyrus Stock, of which there were 75,096,761 shares issued and outstanding, and 10,000,000 shares of preferred stock, par value $0.01 per share, of which there are no shares issued or outstanding. All outstanding shares of Bucyrus Stock issued and outstanding as of December 31, 2009 were duly authorized and validly issued and are fully paid and nonassessable.

- 3-

refusal, preemptive right, right of participation, or any similar right to participate in the transactions contemplated by this Agreement. The issue and sale of the Consideration Shares will not obligate Bucyrus to issue shares of Bucyrus Stock or other securities to any Person (other than Terex) and will not result in a right of any holder of Bucyrus securities to adjust the exercise, conversion, exchange or reset price under any option, right or warrant to acquire (or any similar instrument), or any securities convertible into or exchangeable for, Bucyrus Stock.

SECTION 2.5. Bucyrus Stock. The Consideration Shares will be, when issued in accordance with the terms hereof, duly authorized, validly issued, fully paid and nonassessable, free and clear of any lien, charge, encumbrance, security interest, right of first refusal or other restrictions of any kind, other than as created by the Stockholders Agreement.

SECTION 2.6. SEC Reports; Financial Statements.

(a) Bucyrus has filed or furnished all forms, reports and documents required to be filed or furnished by Bucyrus with the SEC since January 1, 2008 on a timely basis or has timely filed a valid extension of such time of filing and has filed any such Bucyrus SEC Reports prior to the expiration of any such extension. All such required forms, reports and documents (including those that Bucyrus may file subsequent to the date hereof) are referred to herein as the “Bucyrus SEC Reports”. As of the time of their respective filing or furnishing (or if amended or superseded by a later filing prior to the date hereof, then on the date of later such filing), the Bucyrus SEC Reports (i) were or will be prepared in accordance with and complied or will comply with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the SEC thereunder applicable to such Bucyrus SEC Reports, and (ii) did not or will not (or if amended or superseded by a later filing prior to the date hereof, then on the date of such later filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made not misleading.

(b) Each of the consolidated financial statements (including, in each case, any related notes thereto) contained in any Bucyrus SEC Reports (the “Bucyrus Financials”), (i) complied or will comply in all material respects with the published rules and regulations of the SEC with respect thereto, (ii) was or will be prepared in accordance with U.S. GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Forms 10-Q, 8-K or any successor form under the Exchange Act) and conform with the SEC’s Regulation S-X and (iii) fairly presents or will fairly present in all material respects the consolidated financial position of Bucyrus and its Subsidiaries as at the respective dates thereof and the consolidated results of Bucyrus’s operations and cash flows for the periods indicated, except that the unaudited interim financial statements may contain condensed footnotes in accordance with Article 10 of Regulation S-X and were or are subject to recurring year-end adjustments.

(d) Bucyrus maintains a system of internal accounting and financial controls sufficient to provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP in all material respects.

SECTION 2.7. Certain Registration Matters. Assuming the accuracy of Terex’s representations and warranties set forth in Section 3.5, no registration under the Securities Act is required for the offer and sale of the Consideration Shares to Terex under this Agreement. Bucyrus is eligible to register the Bucyrus Stock for resale by Terex under Form S-3 promulgated under the Securities Act. Bucyrus has not granted or agreed to grant to any Person any rights (including “piggy-back” registration rights) to have any of its securities registered with the SEC or any other Governmental Authority that have not been satisfied.

SECTION 2.8. Listing Compliance. Bucyrus is in compliance in all respects with the requirements for continued listing of the Bucyrus Stock on the Trading Market on which the Bucyrus Stock is currently listed. The issuance and sale of the Consideration Shares under this Agreement does not contravene the rules and regulations of the Trading Market on which the Bucyrus Stock is currently listed, and no approval of the stockholders of Bucyrus thereunder is required for Bucyrus to issue and deliver to Terex the Consideration Shares contemplated by this Agreement.

SECTION 2.9. No Other Representations or Warranties. Except for the representations and warranties contained in this Article II, neither Bucyrus nor any other Person makes any other express or implied representation or warranty on behalf of Bucyrus or any Affiliate of Bucyrus with respect to the subject matter of this Agreement.

(a) The execution, delivery and performance by Terex of this Agreement and the Stockholders Agreement and the consummation of the transactions contemplated hereby and thereby, do not and will not (i) violate any provision of the certificate of incorporation or bylaws of Terex; (ii) result in a breach of, or default under, or right to accelerate with respect to, any term or provision of any contract, commitment or other obligation to which Terex or any of its Affiliates is a Party or is subject; or (iii) violate or result in a breach of or constitute a default under any Law or other restriction of any Governmental Authority to which Terex is subject, except with respect to clauses (ii) and (iii), for violations, breaches, defaults, or accelerations as would not reasonably be expected to, individually or in the aggregate, materially impede or delay the ability of Terex to consummate the transactions contemplated by this Agreement.

(b) Other than the Terex Consent, the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby do not require any consent, authorization or approval from any third party or any Governmental Authority on the part of Terex, except for consents, authorizations or approvals, the failure of which to obtain, would not reasonably be expected to, individually or in the aggregate, materially impede or delay the ability of Terex to consummate the transactions contemplated by this Agreement.

SECTION 3.4. No Brokers’ or Other Fees. Except for ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co., whose fees and expenses will be paid by Terex, no broker, finder or investment banker is entitled to any fee or commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of Terex.

Terex acknowledges that none of the Consideration Shares have been registered under the Securities Act or under any state or foreign securities laws, and Terex will not, and shall cause any of its Affiliates that acquire the Consideration Shares not to, sell, transfer or distribute any Consideration Shares except in compliance with the registration requirements or exemption provisions under the Securities Act and the rules and regulations

SECTION 4.2. Listing of the Consideration Shares.

SECTION 4.3. Indemnification. All claims for indemnification under this Agreement shall be made pursuant to, and shall be subject to the limitations and conditions of, Article IX of the ASPA as if such claims were made pursuant to the ASPA.

- 7-

and warranties made pursuant to the ASPA and the representations and warranties contained in Sections 2.1, 2.2, 2.5, 3.1 and 3.2 hereof shall remain in full force and effect and survive indefinitely, and the balance of the representations and warranties contained in this Agreement shall remain in full force and effect and survive for 18 months after the Closing Date.

SECTION 4.4. Conduct of Business Prior to the Closing.

(b) In the event of a merger or consolidation of Bucyrus into another company prior to the Closing as a result of which the outstanding Bucyrus Stock is converted into or exchanged for securities and/or other property or assets of the surviving corporation Terex, rather than being entitled to the Consideration Shares, will be entitled to receive at the Closing the kind and amount of securities and/or other property or assets of the surviving corporation that Terex would have received in respect of the Consideration Shares had it acquired the Consideration Shares immediately prior to the record date for determining the holders of Bucyrus Stock entitled to receive such securities and/or other property or assets in respect of such merger or consolidation.

SECTION 4.5. Further Assurances. Each Party shall use all commercially reasonable efforts to take, or cause to be taken, all appropriate action, do or cause to be done all things necessary, proper or advisable under applicable Law, and execute and delivery such documents and other papers, as reasonably requested by the other Party and necessary to consummate the transactions contemplated by this Agreement, including, but not limited to, satisfying the conditions set forth under Article V hereof.
