SECTION 2.2. Authorization; Enforceability. (a) Bucyrus has all requisite corporate power and authority to execute and deliver this Agreement and the Stockholders

(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.

The issue and sale of the Consideration Shares

-3-

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 parties hereto hereby irrevocably and unconditionally waive trial by jury in any legal action or proceeding relating to this Agreement or any other agreement entered into in connection therewith and for any counterclaim with respect thereto.

SECTION 6.12. Enforcement of Agreement. Each Party acknowledges and agrees that, prior to Closing, the other Party would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement by a Party could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which any Party may be entitled at law or in equity, prior to Closing it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.
