The reporting person disposed of these shares directly to the issuer upon the vesting of previously awarded restricted stock. The purpose of the disposition was to enable the reporting person to satisfy tax withholding obligations that arose upon such vesting, which will be paid by the issuer to the Internal Revenue Service in cash. The reporting person disposed of these shares pursuant to the Agreement and Plan of Merger, dated as of February 6, 2011, as amended (the "Merger Agreement"), among Pride International, Inc. ("Pride"), Ensco plc ("Ensco"), ENSCO International Incorporated and ENSCO Ventures LLC, in exchange for $15.60 in cash and 0.4778 American Depositary Shares, representing Class A ordinary shares of Ensco (each an "Ensco ADS"), per share of Pride common stock. Any fractional shares will be paid in cash. The performance-based restricted stock units generally vest as to one-third annually over a three-year period in an amount ranging from 0-150% of the units awarded based upon company total shareholder return compared with the total shareholder return of a designated peer group over a performance period corresponding to the vesting periods. The units generally provide for payment of all earned shares in common stock following the end of the three-year period. In connection with the merger, all performance-based restricted stock units fully vest and earned shares are paid. Share amounts and exercise price reflect an anti-dilution adjustment made in connection with the August 24, 2009 spin-off of Seahawk Drilling, Inc. The options vested in four equal annual installments beginning on February 9, 2007. Pursuant to the Merger Agreement, Pride stock options fully vest and are assumed by Ensco in the merger and replaced with options to purchase Ensco ADSs, with the same terms and conditions as the original Pride stock options, except that (i) the number of Ensco ADSs purchasable upon exercise of each assumed option is equal to the number of shares of Pride common stock that were purchasable multiplied by 0.7617 and rounded down to the nearest whole Ensco ADS and (ii) the per share exercise price under such assumed option was adjusted by dividing the per share exercise price under such Pride stock option by 0.7617 and rounding up to the nearest whole cent. The options vested in four equal annual installments beginning on January 3, 2008. The options vest in four equal annual installments beginning on January 2, 2009. The options vest in three equal annual installments beginning on January 2, 2010. The options vest in three equal annual installments beginning on January 29, 2011. The options vest in three equal annual installments beginning on January 3, 2012. Elizabeth Wright, attorney-in-fact 2011-06-02
