Item 1.01		Entry into a Material Definitive Agreement

On March 1, 2011, Pride International, Inc. (“Pride”) entered into an Amendment (the “Amendment”) to the Agreement and Plan of Merger (the “Merger Agreement”), dated February 6, 2011, among Pride, Ensco plc (“Ensco”), ENSCO International Incorporated, an indirect, wholly-owned subsidiary of Ensco, and ENSCO Ventures LLC, an indirect, wholly-owned subsidiary of Ensco.

The Amendment revised the certification, exchange and settlement procedures under the Merger Agreement. Under the terms of the Merger Agreement, as amended, shares of Pride common stock held by persons who are unable or fail to timely certify that they are not U.K. residents or, if so, are “qualified investors” within the meaning of Section 86(7) of the U.K. Financial Services and Markets Act 2000 will not receive Ensco American depositary shares (“Ensco ADSs”) (each whole ADS representing one Ensco Class A ordinary share) as part of the merger consideration but will instead be converted into the right to receive for each share of Pride common stock an amount of cash equal to the $15.60 cash component of the merger consideration plus an additional amount equal to the net proceeds of the sale by the exchange agent, Citibank, N.A., of 0.4778 Ensco ADSs. These Pride shares are referred to as cash-only shares. As soon as reasonably practicable after the effective time of the merger, but in any event not later than the second business day after the merger, the exchange agent will send to each record holder of shares of Pride common stock a letter of transmittal, which will include the form of such certification. The exchange agent will also arrange for a comparable certification process using the “agent’s message” system to be established in respect of the book entry Pride shares held in the facilities of The Depository Trust Company. To be considered timely, such certifications must be delivered to the exchange agent no later than ten business days after the exchange agent provides notice and means after the closing date of the merger to deliver such certifications through the facilities of the Depository Trust Company in the case of book entry Pride shares and six months after the closing date of the merger in the case of certificated Pride shares. With respect to book entry Pride shares, if the exchange agent receives certifications for less than 90% of the book entry Pride shares by the end of the initial 10 business day period, Ensco will extend the certification period by up to two additional 10 business day periods.
