The Company's obligation to make any further payments, provide benefits, or continue to employ Employee under this Agreement shall cease in the event that Employee revokes his execution of this Agreement or fails to comply with the terms of this Agreement.  




		
	2.2
	From the Effective Date until 31 December 2015 (the "Employment Period"), Employee shall continue to serve as Executive Vice President and Chief Financial Officer of the Company, subject to the terms of this Agreement.  If the Company and Employee mutually agree that Employee’s employment shall terminate prior to 31 December 2015, Employee shall cease to serve as Executive Vice President and Chief Financial Officer of the Company on the effective date of that termination but the last day of the Employment Period shall still be considered to be 31 December 2015.  If the Company and Employee mutually agree in writing on or prior to 1 December 2015, the parties may extend the Employment Period by such amount of time as is agreed, provided that for as long as Employee shall remain employed after 31 December 2015 Employee shall continue to be paid his base salary on a daily rate computed based on the monthly rate set forth in Section 2.6, and shall continue to be entitled to (i) all payments and benefits described in Section 2.7, (ii) his bonus as provided in Section 3.2(i), and (iii) provided his continued employment is not terminated for “Cause,” receive a pro-rated bonus as provided in Section 3.2(ii). 




		
	2.3
	During the Employment Period, Employee agrees that he will at all times faithfully, industriously and to the best of his ability, experience and talents, perform all of the duties that may be required of and from him by the Company.  Employee shall office in Houston, Texas.













		
	2.4
	During and after the Employment Period, Employee agrees not to make any disparaging comments about the Company, or any current or former officer, director, or employee of the Company, or any affiliate, or to take any action (or assist any person in taking any other action), in each case, that is materially adverse to the interests of the Company or any affiliate or inconsistent with fostering the goodwill of the Company; provided, however, that nothing in this Agreement shall apply to restrict in any way the communication of information by Employee to any state or federal law enforcement agency or require notice to the Company thereof, and Employee will not be in breach of the covenant contained above solely by reason of his testimony which is compelled by process of law.  During and after the Employment Period, the Company and its managing agents authorized to speak on its behalf agree to refrain from making any disparaging comments about Employee; provided, however, that nothing in this Agreement shall apply to restrict in any way the communication of information by the Company to any state or federal law enforcement agency or require notice to Employee thereof, and the Company  will not be in breach of the covenant contained above solely by reason of the testimony of the Company's managing agents which is compelled by process of law.  




		
	2.5
	During the Employment Period, Employee shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by Employee in the performance of his duties hereunder in accordance with the policies of the Company.  Notwithstanding anything to the contrary in this Agreement or in any Company policy with respect to such payments, in-kind benefits and reimbursements provided under this Agreement that would result in taxable compensation income to Employee during any tax year of Employee shall not affect in-kind benefits or reimbursements to be provided in any other tax year of Employee and are not subject to liquidation or exchange for another benefit.  Notwithstanding anything to the contrary in this Agreement, reimbursement requests must be timely submitted by Employee and, if timely submitted, reimbursement payments shall be made to Employee as soon as administratively practicable following such submission in accordance with the Company’s policies regarding reimbursements, but in no event later than the last day of Employee's taxable year following the taxable year in which the expense was incurred.  




		
	2.6
	During the Employment Period, the Company shall pay Employee base salary of $47,916.67 per month. 




		
	2.7
	During the Employment Period, Employee shall continue to be eligible for, and to receive, all compensation and benefits available to executive officers, including, but not limited to, all contributions under the 2005 Supplemental Executive Retirement Plan (the “SERP”), the Ensco Savings Plan (including, but not limited to, the profit sharing provisions thereof), and medical, life and disability insurance and other benefits and insurance coverage, on the same basis as other executive officers.  For the avoidance of doubt, the Company confirms that Employee has fully nonforfeitable interests in his accrued benefits earned under the SERP and the Ensco Savings Plan, including in all cases any deferrals or Company contributions thereunder made through the end of the Employment Period.




		
	2.8
	Effective on the last day of the Employment Period, Employee shall be terminated as an employee of the Company, and, upon compliance with the provisions of this Agreement, Employee shall be entitled to the payments and benefits provided in this Agreement.













		
	2.9
	Because Employee is a United States citizen who has been performing services in the United Kingdom, Employee may be subject to personal income taxation in both the United States and the United Kingdom.  In order to protect Employee from double taxation, Employee shall be entitled to a tax equalization payment compensating Employee for any excess of foreign taxes over the amount of U.S. federal and state taxes Employee would have paid if he had remained an employee in the United States such that the after tax amount actually retained by Employee is equal to the after tax amount Employee would have retained if he had been an employee in the United States (“Tax Equalization Payment”).  The Company shall pay for the cost associated with the preparation of Employee’s tax returns and the resolution of any tax issues that may result from payment received as a result of Employee’s employment with the Company in the United Kingdom in the same manner and to the same extent that the Company provides this benefit to other executives of the Company.  It is Employee’s responsibility to file returns and provide any required documentation on a timely basis to comply with U.S. expatriate tax laws as well as the tax laws of the United Kingdom.  The Company shall neither be responsible nor reimburse Employee for any penalties or interest assessed to or incurred by Employee resulting from or attributable to Employee’s failure to timely file any return or timely provide any required information or documentation.  Notwithstanding anything herein to the contrary, the Tax Equalization Payment provided in this Section 2.9 will only apply with respect to payments and other compensation Employee has received and will receive from the Company and will apply as to (i) any tax periods in which Employee has received or will receive any such payments or other compensation from the Company and (ii) any tax periods in which Employee is subject to taxation in the United Kingdom in respect of his employment with the Company.  For the avoidance of doubt, Employee will be entitled to the Tax Equalization Payment under this Section 2.9 without regard to the reason his employment terminates.  Notwithstanding anything in this Section 2.9 or otherwise in this Agreement, all payments under this Section 2.9 shall be paid no later than the end of the second taxable year of Employee beginning after the taxable year of Employee in which Employee's U.S. Federal income tax return is required to be flied (including any extensions) for the year to  which the compensation subject to the Tax Equalization Payment relates, or, if later, the second taxable year of Employee beginning after the latest such taxable year in which Employee's foreign tax return or payment is required to be filed or made for the year to which the compensation subject to the Tax Equalization Payment relates.  This Section 2.9 is intended to comply with the requirements of Treas. Reg. section 1.409A-1(b)(8)(iii) to cause all payments made under this Section 2.9 to not be treated as a deferral of compensation for purposes of I.R.C. §409A, and the terms of this Section 2.9 shall be implemented in a manner to result in such treatment. 




		
	2.10
	If, prior to the last day of the Employment Period, Employee’s employment with the Company is terminated due to death or Permanent and Total Disability, then the Company shall be obligated to pay and provide all of the payments on benefits specified in this Article II and in Article III hereof to Employee (or to Employee’s spouse and eligible dependents in the event of his death) pursuant to the terms of this Agreement.




		
	2.11
	Notwithstanding any provision in this Agreement to the contrary, if, prior to 31 December 2015, Employee voluntarily resigns his employment with the Company or the Company terminates Employee for Cause, then the Company shall not be obligated to pay or provide further any of the payments and benefits specified in this Article II or any of the payments or benefits specified in Article III hereof.















III. RETIREMENT PACKAGE


		
	3.1
	Not later than fifteen (15) business days after the last day of the Employment Period, the Company will pay Employee all regular pay due through his last day of employment, less withholdings required by state and/or federal law.  Employee agrees that this payment includes all accrued employment benefits payable to Employee, including without limitation all salary, wages, compensation, accrued and unpaid vacation leave, and any other paid time off earned and owed through his last day of employment. 


 
		
	3.2
	Provided that Employee executes and does not revoke a release, in the form attached as Exhibit A, effective on the last day of the Employment Period, the Company represents to Employee that the Committee will take all actions pursuant to the provisions of the 2005 ECIP necessary to consider Employee to have retired on or after his “normal retirement age” under the 2005 ECIP and (i) to determine Employee's 2015 target annual performance bonus under the 2005 ECIP without any proration in accordance with Section 7(c) thereof, which amount will be payable at the time specified in the 2005 ECIP, and (ii) if the last day of the Employment Period is after 31 December 2015, Employee will be entitled to payment within thirty (30) days of that date of one hundred percent (100%) of his 2016 target annual performance bonus subject to proration under the 2005 ECIP of $460,000 (which is consistent with the amount of his 2015 target annual performance bonus).  Employee agrees that he shall not be eligible to receive a severance benefit under any Company severance plan, policy, or program.




		
	3.3
	In exchange for the mutual promises contained herein, effective on the last day of the Employment Period, the Company represents to Employee that the Committee will take all actions pursuant to the provisions of the 2012 LTIP necessary to (i) provide for acceleration (full vesting) as of the last day of the Employment Period of all unvested restricted share awards and restricted share unit awards heretofore granted to Employee, and (ii) consider Employee to have retired on or after his “normal retirement age” under the 2012 LTIP and determine the performance unit awards granted after 2012 to Employee under the 2012 LTIP in accordance with Section 15(b) thereof; provided, however, that any restricted share units that vest upon the last day of the Employment Period pursuant to clause (i) shall not be paid or settled until the original vesting date specified in the award agreement under which they were granted and payment under the performance unit awards referred to in clause (ii), and the accrued aggregate dividend equivalents attributable to each such amount, shall be made at the time specified in the applicable performance unit award agreements.  Employee shall not be eligible for the grant of any additional award or awards under the 2012 LTIP. 




		
	3.4
	Employee may exercise, trade or otherwise divest vested NSOs in accordance with the 2005 LTIP and the specific NSO award agreements, provided that each NSO shall remain exercisable by Employee for a period ending on the earlier of (i) the second anniversary of the last day of the Employment Period, or (ii) the last day of the term of the NSO.  




		
	3.5
	The parties acknowledge that the Retirement Package described in this Article III constitutes a reasonable settlement or compromise to any amount which Employee may claim or be entitled to as part of Employee's employment and/or as a result of the termination of Employee's employment with the Company, and the parties acknowledge that the 











consideration set forth in this Agreement constitutes additional consideration above and beyond which Employee is or otherwise would be entitled.

	5.4
	Employee is not releasing any rights or claims arising after the date that Employee executes this Agreement; provided, however, that Employee acknowledges and agrees that the release contained herein includes any claims related to his separation from employment with the Company.  













		
	5.5
	Notwithstanding anything to the contrary provided in this Article V, Employee is not releasing any right to: (i) any vested benefit under any employee benefit plan, as defined by the Employee Retirement Income Security Act of 1974, as amended, (ii) any rights to COBRA continuation coverage, or (iii) any rights provided in this Agreement.  Further, nothing in this Agreement shall affect the Equal Employment Opportunity Commission's ("EEOC") rights and responsibilities to enforce any law under its jurisdiction, nor shall anything in this Agreement be construed as a basis for interfering with Employee's right to file a timely charge with, or participate in an investigation or proceeding conducted by, the EEOC or any other fair employment practices agency; provided, however, if the EEOC or any other agency or person  commences an investigation or pursues any type of claim on Employee's behalf, Employee specifically waives and releases his right, if any, to recover any monetary or other benefits of any sort whatsoever arising from any such investigation or claim, nor will Employee seek or accept reinstatement to his former position with the Company.




		
	5.6
	Employee stipulates and agrees that: (i) Employee has no work‐related physical or mental injury incurred or sustained during Employee's employment with the Company, or any other "injury" as defined in the Texas Labor Code; (ii) Employee is not a "prevailing party" under 42 U.S.C. 2000e‐5(k), 42 U.S.C. 1988, the Texas Labor Code, or any other federal, state or local law; and (iii) Employee has not filed or authorized the filing of any complaints, charges, or lawsuits against the Company with any court or agency, nor has Employee assigned to any third party or member of Employee's family any right of Employee to pursue any complaint, charge, lawsuit or claim against the Company.




		
	5.7
	During the Employment Period, the Company promises to provide Employee, and Employee acknowledges and agrees that during his employment, he acquired Confidential Information and will continue to acquire Confidential Information during the Employment Period. Therefore, Employee agrees that in order to protect the Company's Confidential Information and the Company's legitimate business interests, it is necessary to enter into the restrictive covenants set forth in this Section 5.7 (collectively, the "Restrictive Covenants").  Employee may not circumvent the purpose of any restriction by participating in a Competing Business through remote means like telephone, facsimile, correspondence, or electronic communication.




		
	a.
	Employee agrees that (i) he will not at any time after the end of the Employment Period, directly or indirectly, divulge, disclose or communicate any Confidential Information to any person, firm, corporation or entity in any manner whatsoever, except for such disclosures by Employee that are required by law or any valid order or other process issued by any court or administrative agency or self-regulating organization; and (ii) he shall not fail to return to the Company all records, notes, files, drawings, documents, plans and like items, and all copies thereof, relating to or containing or disclosing Confidential Information that are in Employee’s possession or otherwise in his control, whether or not requested to do so by the Company.











		
	b.
	Employee agrees that for a period of one (1) year following the end of the Employment Period or for a period of one (1) year following termination with Cause, whichever is applicable, Employee will not, either directly or indirectly, hire, call on, solicit, divert, or take away, or attempt to call on, solicit, divert, or take away any of the employees, officers, subcontractors, suppliers or customers  of the Company, or the patronage of any employees, subcontractors, suppliers or customers of the Company, or encourage any employees, officers, subcontractors, suppliers or customers of the Company to terminate their relationship with the Company or otherwise interfere with or disturb the relationship existing between the Company and its employees or customers. Employee recognizes that such solicitation would constitute tortious interference with contract and tortious interference with a business relationship as well as a breach of this Agreement. 


		
	c.
	Employee agrees for a period of one (1) year following the end of the Employment Period or for a period of one (1) year following a termination with Cause, whichever is applicable, Employee will not participate in a Competing Business. For purposes of this Paragraph, "participate in" includes entering into, engaging in, participating in, or assisting a Competing Business, directly or indirectly, whether as an employee, agent, consultant, partner, owner, shareholder (other than through ownership of publicly-traded capital stock of a corporation which represents less than five percent (5%) of the outstanding capital stock of such corporation), lender, manager, officer, director, or in any other business capacity or relationship.  Employee agrees that competition in violation of these terms is intrinsically unfair to the Company because it would involve inevitable disclosure and misappropriation of Confidential Information.  In the event that Employee desires to pursue a business or employment opportunity which potentially violates this Section 5.7, he shall seek a written waiver from the Company by providing written notice to the Chief Executive Officer of the Company.  The Company may, in its sole discretion, refuse to waive its rights hereunder. 


		
	d.
	The Restrictive Covenants shall survive any expiration or termination of this Agreement and the termination of Employee's employment with the Company. If Employee violates any of the Restrictive Covenants, the restrictive period shall be suspended and will not run in favor of Employee from the time of the commencement of any such violation until the time when the Employee cures the violation to the Company's satisfaction. 


		
	e.
	Employee acknowledges that the Restrictive Covenants, in view of the nature of the Company's business, are reasonable and necessary to protect the Company's legitimate business interests and that any violation of the Restrictive Covenants would result in irreparable injury to the Company. In the event of a breach or a threatened breach by Employee of any Restrictive Covenant, the Company shall be entitled (without the necessity of posting bond in excess of $1,000 against such breach or threatened breach) to a temporary restraining order, temporary injunction, and permanent injunction restraining Employee from the commission of any breach, merely by proving (by a preponderance of the evidence) the existence of such breach, or threatened breach and without the necessity of proving either inadequate remedy at law or irreparable harm, and to recover the Company's attorneys' fees, costs and expenses related to the breach or threatened breach. Nothing contained in this Agreement shall be construed as prohibiting the Company from pursuing any other remedies available to it for any breach or threatened breach, including, without limitation, the recovery of money damages, specific performance, attorneys' fees, and costs. The Restrictive Covenants shall each be construed as independent of any 











other provisions in this Agreement, and the existence of any claim or cause of action by Employee against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the Restrictive Covenants. 
		
	f.
	The Parties agree that if a court should decline to enforce any of the Restrictive Covenants, such affected provisions shall be deemed to be modified to restrict the competitive activity to the maximum extent in time, scope, and geography, which the court shall find enforceable. 


		
	g.
	The Parties agree and stipulate that: (i) the Restrictive Covenants are fair and reasonable in light of all of the facts and circumstances of the relationship between Employee and the Company and do not impose a greater restraint than is necessary to protect the legitimate business interests of the Company; (ii) the consideration and Confidential Information provided by the Company to Employee is not illusory; and (iii) the Company would not have entered into this Agreement but for the agreement of Employee to be bound by the Restrictive Covenants.


		
	h.
	If it is determined by a court of competent jurisdiction in a final, non-appealable order that Employee has willfully and materially engaged in an activity in violation of Section 2.4 and/or 5.7 during or within one year after the end of the Employment Period, then Employee shall repay to the Company, or its designee, within five (5) business days of receipt of written demand therefor, an amount in good funds equal to any cash payments received by Employee pursuant to Sections 3.2 and 3.3.  




		
	5.8
	Should Employee in any manner materially, whether directly or indirectly, fail to perform any covenant of Employee provided herein or otherwise materially breach this Agreement in any respect, the Company shall have no further or continuing obligation to perform any covenants of the Company for which this Agreement provides, including payment of any sums for which this Agreement provides.  If, however, Employee’s Employment Period is extended beyond 31 December 2015 by mutual agreement pursuant to Section 2.2, Employee shall be entitled to payment of his bonus provided in Section 3.2(i) regardless of whether his continued employment is terminated for Cause during 2016.  






VI. MISCELLANEOUS


		
	6.1
	Employee acknowledges that he has carefully read this Agreement and that he has had a reasonable opportunity to review its terms with legal counsel of his choice.

	•
	In exchange for receiving the consideration in Sections 3.2 and 3.3 of the Retirement Agreement, you agree to irrevocably and unconditionally release the Company (as defined in the Retirement Agreement) from any and all claims, (a) any claim for any wages, salary, compensation, vacation pay, paid leave or other remuneration of any kind; (b) any claim for additional or different compensation or benefits of any sort; (c) any claim of retaliation or discrimination on the basis of race, sex, religion, marital status, sexual preference, age, national origin, handicap or disability, veteran status, or special disabled veteran status; (d) any claim arising under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Equal Pay Act, the Age Discrimination in Employment Act of 1967, the Employee Retirement Income Security Act of 1974, the Americans with Disabilities Act, the Family and Medical Leave Act, the Fair Labor Standards Act of 1938, the Sarbanes-Oxley Act, the Dodd-Frank Act, the Texas Commission on Human Rights and/or the Equal Employment Opportunity Commission, and any amendments to such statutes; (e) any and all state wage payment and unemployment laws; (f) any claim arising out of or related to an express or implied employment contract, any other contract affecting terms and conditions of employment, or a covenant of good faith and fair dealing; (g) any claim for personal injury or property damage; (h) any claim for defamation, invasion of privacy, negligence, breach of fiduciary duty, fraud or misrepresentation; (i) any claim arising under any anti-retaliation or whistleblower provisions of any state or federal law; (j) any claim based on any other federal and/or state laws and/or regulations related to and/or addressing employment and separation from employment; and (k) any claim based on any other statutory prohibition or any other tort.  Notwithstanding any other provision of this Agreement, the Deed of Indemnity signed by you on 22 December 2009 shall continue in effect in all respects during your continued employment and for such period of time following the termination of employment as are established in section 15 of such Deed of Indemnity. Further, you will be entitled to the benefit of any insurance policies the Company maintains for the benefit of its officers and directors against all liabilities, claims, costs, charges and expenses incurred in connection with any action, suit or proceeding to which you may be made, or threatened to be made, a party, witness or other participant by reason of being an officer or employee of the Company.




		
	•
	You further agree that this Agreement specifically incorporates all Sections of the Retirement Agreement and that you continue to be obligated to follow those terms.  













		
	•
	You may revoke this Agreement by notice to the Company, in writing, within seven (7) days of the date of its execution by you (the “Revocation Period”). You agree that you will not receive the consideration provided by in Sections 3.2 and 3.3 of the Retirement Agreement if you revoke this Agreement.  You also acknowledge and agree that if the Company has not received from you notice of your revocation of this Agreement prior to the expiration of the Revocation Period, you will have forever waived your right to revoke this Agreement and this Agreement shall thereafter be enforceable and have full force and effect.
