Item 1.01. Entry into a Material Definitive Agreement

On November 9, 2009, ENSCO International Incorporated, a Delaware corporation (the “Company”), announced a plan to reorganize its corporate structure and relocate its headquarters to the United Kingdom. In connection with the restructuring, the Company entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with ENSCO Newcastle LLC, a newly formed Delaware limited liability company (“Ensco Mergeco”) and wholly owned subsidiary of ENSCO Global Limited, a newly formed Cayman Islands exempted company (“Ensco Cayman”) and wholly owned subsidiary of the Company. Under the Merger Agreement, Ensco Mergeco will merge with and into the Company, with the Company being the surviving company (the “Merger”) and an indirect subsidiary of a newly formed public limited company to be named “Ensco International plc” or a similar name (“Ensco UK”), incorporated under English law. Ensco UK is currently a private limited company named “ENSCO International Limited” and is a wholly owned subsidiary of the Company.

If approved by the stockholders, subject to certain conditions and upon consummation of the Merger, each stockholder of the Company will have the right to receive a number of American depositary shares (collectively, the “ADSs”), representing Class A Ordinary Shares of Ensco UK, equal to the number of shares of common stock of the Company that the stockholder holds at the effective time of the Merger. Upon completion of the Merger, Ensco UK and its subsidiaries will own and continue to conduct in substantially the same manner the business that the Company and its subsidiaries currently conduct.

Ensco UK has filed a registration statement on Form S-4, which includes a proxy statement/prospectus and other relevant materials in connection with the proposed Merger. The proxy statement/prospectus will be mailed to the Company’s stockholders once the registration statement has been declared effective by the Securities and Exchange Commission.

The foregoing description of the Merger and related transactions does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, filed as Exhibit 2.1 and incorporated into this report by reference.
