SUBSEQUENT EVENTS</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On October 5, 2010, we purchased all of the equity of Acute Technological Services, Inc. (“Acute”). Headquartered in Houston, Texas with additional operations in Brazil, Acute provides metallurgical and welding services to the oil and gas industry in support of critical, complex subsea component manufacturing and deepwater riser fabrication on a global basis. Subject to customary post-closing adjustments, total consideration for the transaction was $30.3 million, which was funded from cash on hand and borrowings under the Company’s existing credit facility. Acute’s operations will be reported as part of our offshore products segment. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On October 14, 2010, we agreed to a Scheme of Arrangement with The MAC Services Group Limited (“The MAC”), a leading provider of remote accommodations for the natural resource industry in Australia, pursuant to which we will acquire all of the ordinary shares of The MAC. Under the terms of the Scheme, each shareholder of The MAC will receive A$3.90 per share in cash, which will be reduced by any dividends declared or paid subsequent to October 15, 2010. This offer price represents a total purchase price of A$651 million, or approximately $644 million based on exchange rates as of October 14, 2010. The Board of The MAC unanimously recommended that The MAC shareholders vote their shares in favor of the Scheme. The Company expects the transaction to close by the end of the first quarter of 2011. The Company intends to fund the acquisition with cash on hand and borrowings expected to become available under a new five-year, $900 million senior secured bank facility for which it has an executed commitment letter with the lead underwriting bank. The transaction is subject to certain conditions precedent including approvals from the shareholders of The MAC, the court approval of the Scheme and other regulatory approvals. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Describes disclosed significant events or transactions that occurred after the balance sheet date, but before the issuance of the financial statements.
