3. Sections 3.5, 14.1 and 14.11(c) are hereby amended to replace any reference to Ensco ADSs with a reference to Ensco UK Shares.

4. Section 13.2 of the Plan is hereby amended by adding the following paragraph to the end thereof to read as follows:

If a Participant was a participant in the Pride 401(k) Plan on 31 December 2011 and became a Participant in the Plan on 1 January 2012 (a “Pride Participant”), then, notwithstanding the above vesting schedule in this Schedule 13.2, the entire Employer Account of each Pride Participant shall become nonforfeitable and fully vested on the date he attains age 55.

5. Section 20.6 of the Plan is hereby amended to read as follows:

Sec. 20.6 Voting of Ensco UK Share. The Trustee shall, upon receipt of notice to it of any meeting at which the holders of Ensco UK Shares are entitled to vote, promptly send (or cause a third party to send, at the expense of the Company) each Participant and Former Participant a copy of the proxy solicitation materials, together with a form requesting confidential voting instructions to the Trustee regarding the Ensco UK Shares allocated to his Individual Account. Each Participant and Former Participant shall be entitled to direct the Trustee as to the manner in which the Trustee is to vote all Ensco UK Shares (including fractional Ensco UK Shares) allocated to his Individual Account, provided he delivers instructions to the Trustee to vote the Ensco UK Shares at least five business days prior to the date such vote shall be required (or such other period of time as may be required by the Trustee). In the event a Participant or Former Participant delivers conflicting instructions, the instructions delivered last in time shall control. In the event a Participant or Former Participant fails to deliver such instructions, the Trustee shall vote, such Ensco UK Shares proportionately to the ratio of the votes of the Participants and Former Participants who have delivered voting instructions to the Trustee. Voting instructions may be given only in respect of a number of Ensco UK Shares representing an integral number of the Ensco UK Shares. All instructions shall be maintained by the Trustee to safeguard the confidentiality of the instructions.

6. Section 20.7 of the Plan is hereby amended to read as follows:

Sec. 20.7 Tender and Exchange Offers. The provisions of this Section 20.7 shall apply in the event that a tender offer (as defined below) is made for the Ensco UK Shares or an offer to exchange securities (as defined below) for the Ensco UK Shares which are subject to the U.S. Securities Act of 1933, as amended, is made.

(a) Definitions. A tender offer and an exchange offer or offer to exchange shall have the meanings set forth below:

(b) Notice and Directions. Upon such a tender or exchange offer occurring, the Company and the Trustee shall utilize their best efforts to notify each affected Participant and Former Participant and to cause to be distributed to him such information as will be distributed to the holders of the Ensco UK Shares, generally in connection with any such tender or exchange offer and a form by which the Participant or Former Participant may direct the Trustee in writing as to what action, as set forth below, to take on behalf of that Participant or Former Participant with respect to the Ensco UK Shares allocated to his Individual Account under the Plan. If the Trustee does not receive such written directions from a Participant or Former Participant, the Trustee shall not tender or deliver in acceptance of the exchange offer any of the Ensco UK Shares held in that Participant’s or Former Participant’s Individual Account.

(c) Cash Tender Offer. In connection with a cash tender offer for Ensco UK Shares, a Participant or Former Participant may direct the Trustee to tender any or all Ensco UK Shares held in the Participant’s or Former Participant’s Individual Account. Any cash received by the Trustee as a result of such tender shall be invested by the Trustee in such short-term interest bearing investments as it deems appropriate pending direction from Participants and Former Participants regarding the reinvestment of such cash in the Investment Funds then available under the Plan.

(d) Exchange Offer. In connection with an exchange offer for Ensco UK Shares, a Participant or Former Participant may direct the Trustee to deliver in acceptance of the exchange offer any or all Ensco UK Shares held in the Participant’s or Former Participant’s Individual Account. Any property received by the Trustee in connection with such exchange shall be held by the Trustee in separate accounts for the affected Participants and Former Participants pending directions from them regarding the reinvestment of such property in the Investment Funds that are available under the Plan.

(e) Tender and Exchange Offer. In connection with a combination tender and exchange offer for Ensco UK Shares, a Participant or Former Participant may direct the Trustee to tender and offer for exchange any or all Ensco UK Shares held in the Participant’s or Former Participant’s Individual Account with any cash received by the Trustee as a result of such tender treated as provided in subsection (c) above and any property received by the Trustee in connection with the exchange treated as provided in subsection (d) above.

(f) Revocation of Directions. A tender or exchange offer direction given by a Participant or Former Participant may be revoked by the Participant or Former Participant by completion of the form prescribed therefor by the Administrator, provided such form is filed with the Trustee at least two business days prior to the withdrawal-date-deadlines provided for in the regulations with respect to tender or exchange offers prescribed by the Securities and Exchange Commission or other applicable law.

(g) Best Efforts. The Trustee shall use its best efforts to effect on a uniform and nondiscriminatory basis the sale or exchange of the Ensco UK Shares as directed by the Participants and Former Participants. However, neither the Administrator, the Committee nor the Trustee insures that all or any part of the Ensco UK Shares directed by

-12-

a Participant or Former Participant to be tendered or exchanged will be accepted under the tender or exchange offer. Any such Ensco UK Shares not so accepted shall remain in the Participant’s or Former Participant’s Individual Account and the Participant or Former Participant shall continue to have the same rights with respect to such Ensco UK Shares as he had immediately prior to the Trustee’s tendering of the Ensco UK Shares.

(h) Conditional Obligations of the Trustee. Any obligation belonging to the Trustee under the foregoing provisions of this Section 20.7 is conditional upon the tender offer or exchange offer:

(ii) being carried out in compliance with any requirement to file a prospectus or other filing with, or obtain prior consent, approval, authorization from, or a license, order, registration, qualification or decree of any court or governmental authority or agency or supervisory body.

If the conditions above are not met, the Trustee will not be required to perform such obligation.

If a tender or exchange offer is made, the Administrator shall adopt such rules, prescribe the use of such special administrative forms and procedures, delegate such authority, take such action and execute such instruments or documents and do every other act or thing as shall be necessary or in its judgment proper for the implementation of this Section 20.7. All instructions from Participants and Former Participants regarding a tender or exchange offer shall be maintained by the Trustee to safeguard the confidentiality of the instructions.

Notwithstanding anything in the Plan to the contrary, in administering the tendering or exchange of Ensco UK Shares pursuant to the applicable provisions of the Plan, it is intended that the confidentiality of the tenders or exchanges, as the case may be, made by Participants or Former Participants pursuant to the provisions of the Plan shall be maintained by the Trustee as may be contemplated by applicable law.
