Item 5.07 Submission of Matters to a Vote of Security Holders.

A special meeting of the stockholders of Allis-Chalmers was held on February 23, 2011 (the “Special Meeting”). At the Special Meeting, Proposals 1 and 2 were approved by Allis-Chalmers’ stockholders. The proposals are described in detail in the definitive proxy statement/prospectus, as amended, filed by Allis-Chalmers with the SEC on January 25, 2011. At the Special Meeting, more than 50% percent of the shares of Allis-Chalmers’ common stock outstanding and 100% of the shares of Allis-Chalmers’ preferred stock entitled to vote as of the record date of January 14, 2011, were represented in person or by proxy. The voting results of the Special Meeting are set forth below.

Proposal 1 — Approval of Merger Agreement – Allis-Chalmers’ stockholders adopted the Merger Agreement. The voting results were 65,496,199 shares of common stock (including Allis-Chalmers’ preferred stock voting on an as-converted basis with the common stock as a single class, subject to the limitations described in the proxy statement) and 36,393 shares of preferred stock “FOR,” 568,500 shares of common stock and 0 shares of preferred stock “AGAINST,” and 61,466 abstentions.

Proposal 2 — Approval of Amendment to Certificate of Designations – Allis-Chalmers’ stockholders adopted the amendment to the Certificate of Designations. The voting results were 65,362,082 shares of common stock (including Allis-Chalmers’ preferred stock voting on an as-converted basis with the common stock as a single class, subject to the limitations described in the proxy statement) and 36,393 shares of preferred stock “FOR,” 568,085 shares of common stock and 0 shares of preferred stock “AGAINST,” and 177,998 abstentions.

Proposal 3 — Adjournment of Special Meeting to Solicit Additional Proxies if there is an Insufficient Number of Votes to Approve the Merger Agreement – Allis-Chalmers’ stockholders approved the proposal to adjourn the Special Meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if there had been an insufficient number of votes at the time of such adjournment to approve the Merger Agreement. The voting results were 62,538,132 shares of common stock (including Allis-Chalmers’ preferred stock voting on an as-converted basis with the common stock as a single class, subject to the limitations described in the proxy statement) and 36,393 shares of preferred stock “FOR,” 3,037,663 shares of common stock and 0 shares of preferred stock “AGAINST,” and 550,371 abstentions. Because sufficient proxies were returned, no proposal to adjourn or postpone the Special Meeting was made, and therefore no vote was held on this proposal.
