To the extent that a Shareholder makes a capital contribution to the Company, that Shareholder shall revise Exhibit A hereto. 11. Management and Control. (a) The Company shall be managed exclusively by the Shareholders. The Shareholders shall have the right, power, authority and discretion to conduct the business and affairs of the Company to take any and all actions (including, without limitation, executing, delivering and performing on behalf of the Company any and all agreements, instruments, certificates or other documents) and do any and all things necessary, desirable, convenient or

5 incidental to carry on the business and purposes of the Company, and shall have and may exercise all of the powers and rights conferred upon a manager of a limited liability company formed pursuant to the Act. (b) The initial officers (the “Officers” or, individually, an “Officer”) of the Company as designated by ENSCO Holding are listed on Schedule A hereto. Any successor Officers of the Company shall be chosen by the Shareholders and may consist of one or more persons as a chairman, president, vice president, secretary, treasurer and/or any other title of an Officer of the Company, as determined by the Shareholders, to act on behalf of the Company with respect to any matter or matters delegated to such person by the Shareholders. No such delegee or Officer need be a resident of the State of Delaware. Any number of offices may be held by the same person. The Shareholders may appoint such other Officers and agents as they shall deem necessary or advisable, who shall hold their offices for such terms and shall exercise such powers and perform such duties as shall be determined from time to time by the Shareholders. The Officers of the Company shall hold office until (i) their successors are chosen and qualified or (ii) they are removed by the Shareholders. Any Officer may be removed at any time, with or without cause, by the Shareholders. The Officers are agents of the Company for the purpose of the Company’s business and the actions of the Officers taken in accordance with such powers shall bind the Company. 12. Exculpation and Indemnification. No Shareholder, director, Officer or other authorized agent of the Company shall be liable to the Company, or any other person or entity who has an interest in the Company, for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of the authority conferred on such person by this Agreement, except that such person shall be liable for any such loss, damage or claim incurred by reason of such person’s willful misfeasance. In the event that the Shareholders, or any of their direct or indirect members, partners, directors, managing directors, officers, stockholders, employees, agents, affiliates or controlling persons, or any director or officer of the Company (collectively, the “Indemnified Persons”; and each an “Indemnified Person”), becomes involved, in any capacity, in any threatened, pending or completed, action, suit proceeding or investigation, in connection with any matter arising out of or relating to the Company’s business or affairs, to the fullest extent permitted by applicable law, any legal and other expenses (including the cost of any investigation and preparation) incurred by such Indemnified Person in connection therewith shall, from time to time, be advanced by the Company prior to the final disposition of such action, suit, proceeding or investigation upon receipt by the Company of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall ultimately be determined that such Indemnified Person is not entitled to be indemnified by the Company in connection with such action, suit proceeding or investigation as provided in the exception contained in the next succeeding sentence. To the fullest extent permitted by law, the Company also will indemnify and hold harmless an Indemnified Person against any losses, claims, damages, liabilities, obligations, penalties, actions, judgments, suits, proceedings, costs, expenses and disbursements of any kind or nature whatsoever (collectively, “Costs”), to which such an Indemnified Person may become subject in connection with any matter arising out of or in connection with the Company’s business or affairs, except to the extent that any such Costs result solely from the willful misfeasance of such Indemnified Person. If for any reason (other than the willful misfeasance of such Indemnified Person) the foregoing indemnification is

6 unavailable to such Indemnified Person, or insufficient to hold it harmless, then the Company shall contribute to the amount paid or payable by such Indemnified Person as a result of such Costs in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and such Indemnified Person on the other hand but also the relative fault of the Company and such Indemnified Person, as well as any relevant equitable considerations. The reimbursement, indemnity and contribution obligations of the Company under this Section 10 shall be in addition to any liability which the Company may otherwise have to any Indemnified Person and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company and any Indemnified Person. The reimbursement, indemnity and contribution obligations of the Company under this Section 10 shall be limited to the Company’s assets, and no Shareholder shall have any personal liability on account thereof. The foregoing provisions shall survive any termination of this Agreement. 13. Dissolution. (a) The Company shall dissolve, and its affairs shall be wound up upon the first to occur of the following: (i) the written consent of all the Shareholders to dissolve the Company and (ii) the entry of a decree of judicial dissolution under Section 18-802 of the Act. (b) The bankruptcy (as defined in Section 18-101(1) and 18-304 of the Act) of any Shareholder shall not cause that Shareholder to cease to be a member of the Company and upon the occurrence of such an event, the business of the Company shall continue without dissolution. (c) In the event of dissolution, the Company shall conduct only such activities as are necessary to wind up its affairs (including the sale of the assets of the Company in an orderly manner), and the assets of the Company shall be applied in such manner, and in such order of priority, as determined by the Shareholders, subject to any requirements of the Act. (d) In connection with the winding-up of the Company, any surplus assets of the Company shall be distributed to the Shareholders pro rata in accordance with their respective shareholdings. The Company shall terminate when (i) all of the assets of the Company, after payment of or due provision for all debts, liabilities and obligations of the Company shall have been distributed to the Shareholders in the manner provided for in this Agreement and (ii) the Certificate of Formation has been cancelled in the manner required by the Act. 14. Treatment for Tax Purposes. It is the intention of ENSCO Holding that the Company be treated as an entity disregarded from its owner for federal, state and local income tax purposes. 15. Capital Contributions. Without creating any rights in favor of any third party, the Shareholders may, from time to time, make contributions of cash or property to the capital of the Company, but shall have no obligation to do so. 16. Distributions. Distributions shall be made to the Shareholders at the times and in the aggregate amounts determined by the Shareholders. Once the aggregate amounts of such

7 distributions have been determined, such amounts shall be distributed to the Shareholders in accordance with the number of Shares then held by them. 17. Allocation of Profit and Losses. The Company's profits and losses shall be notionally allocated to the Shareholders pro rata in accordance with their respective shareholdings. Any notional allocation made pursuant to this section shall have effect for U.S. income tax purposes only, and no notional allocation made pursuant to this section shall give any Shareholder any personal or proprietary right to or in respect of the profits of the Company or any personal or proprietary right to receive any distribution of, or any other payment in respect of, such profits. 18. Title. Legal title to all assets, rights and property, whether real, personal or mixed, conveyed to, or held or acquired by, the Company shall reside in the Company and shall be conveyed only in the name of the Company. No Shareholder shall have any interest in any specific assets of the Company and no Shareholder shall have the status of a creditor with respect to any distribution pursuant to this Agreement. 19. No Fiduciary Duties. No Shareholder shall have any duties (including any fiduciary duties) to the Company, any subsidiary or any other Shareholder, whether or not such duties arise or exist at law or in equity, and each Shareholder hereby expressly waives any such duties (including any fiduciary duties). 20. Admission of Additional Shareholders. One or more additional persons or entities may be admitted as a Shareholder of the Company with the consent of all the Shareholders and in accordance with the provisions set out in this Agreement. 21. Amendments. This Agreement may not be modified, altered, supplemented or amended except pursuant to a written agreement executed, delivered, and agreed by all the Shareholders. 22. Limited Liability. Except as otherwise provided by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Shareholders shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Shareholder of the Company. 23. No Third Party Beneficiaries. The right or obligation of the Shareholders to call for any capital contribution or to make a capital contribution or otherwise to do, perform, satisfy or discharge any liability or obligation of the Shareholders hereunder, or to pursue any other right or remedy hereunder or at law or in equity, shall not confer any right or claim upon or otherwise inure to the benefit of any creditor or other third party having dealings with the Company; it being understood and agreed that the provisions of this Agreement shall be solely for the benefit of, and may be enforced solely by, the Shareholders and their successors and assigns except as may be otherwise agreed to by the Company in writing with the prior written approval of all the Shareholders. 24.
