THE RIG

2.1 Rig Construction

(a) Contractor warrants that the Rig shall be constructed and delivered by Builder in accordance with the Specifications.

(b) If, after the Effective Date, ABS or a Governmental Authority makes any revisions or additions to its requirements applicable to the Rig, compliance with which is required to preserve the Rig in the class certification of “DPS-3” “Maltese Cross A1E” or for the continued efficient use of the Rig under this Drilling Contract, Contractor undertakes to notify Operator of (i) the nature and extent of such change, (ii) the latest date (taking into account, with respect to Governmental Authority or classification society requirements, any extension available to Contractor) by which such compliance with such change will be necessary, and (iii) the estimated time which will be required for carrying out such change.

(c) Contractor shall notify Operator of any request by Builder, Rowan Gibraltar or Contractor to make any material change in Specifications for the Rig. Contractor shall prepare a request which describes (i) the nature and extent of such change, (ii) the estimated time which will be required for carrying out such change, and (iii) the impact such change is reasonably likely to have on the Earliest Acceptance Date and/or the Latest Delivery Date. Such changes shall be carried out only with the consent of Operator (such consent not to be unreasonably withheld, conditioned or delayed) and shall not reduce or modify any of Contractor’s obligations hereunder with respect to delivery or performance of the Rig unless otherwise agreed upon by Operator.

(d) During the construction period (including during all sea trials and DP trials), Operator’s representatives shall be entitled to access the Rig, at Operator’s risk, cost and expense, except to the extent prohibited by the contract governing the construction and delivery of the Rig by Builder, including attendance at all tests and trials of the Rig, her equipment, appurtenances, and components. Contractor shall promptly notify Operator of all such tests and trials and cause Builder and Rowan Gibraltar to provide Operator’s representatives with access to attend. Operator’s representatives shall not interfere with such tests or trials. All communications between Operator and Builder shall be through Contractor or Rowan Gibraltar. Contractor shall also provide Operator’s representatives with access to the worksites and representatives of the BOP manufacturer at Operator’s risk, cost and expense.

(e) Contractor shall provide Operator with periodic progress reports advising of progress on the planning and construction of the Rig and the BOPs. The first such report shall be provided within three (3) months after the Effective Date. Thereafter, Contractor shall provide Operator with progress reports at least once every month until Contractor accepts delivery, respectively, of the Rig from Builder and the owner-furnished BOP from the BOP manufacturer. Each progress report shall be in writing in a form from time to time proposed by Contractor and approved by Operator and shall include statements of any events or circumstances which may cause the Earliest Acceptance Date and/or the Latest Delivery Date to be delayed and the estimated period of such delay. Contractor shall also deliver to Operator from time to time copies of construction progress certificates (i) of Builder (which certificates shall include percentages of completion of the Rig and other major components) as and when issued by Builder and (ii) of the BOP manufacturer (which certificates shall include percentages of completion of the Builder-furnished BOP and the owner-furnished BOP) as and when issued by the BOP manufacturer.

(f) Not later than the Earliest Acceptance Date, Contractor will provide to Operator, at no cost to Operator, a Builder’s model (with a scale of no less than 1:200) of the Rig.

(g) As and when requested in writing by Operator, Contractor shall meet with Operator at Contractor’s facilities or at Builder’s shipyard (or such other place mutually acceptable to the Parties) for the purpose of evaluating the progress of the Rig’s construction. Contractor shall cause Builder and Rowan Gibraltar to permit Operator and a reasonable number of Operator’s representatives to be present at Builder’s shipyard for such purposes at Operator’s risk, cost and expense; provided that any such meetings at Builder’s shipyard shall occur during ordinary working hours and shall not obstruct the normal or orderly construction of the Rig.

(h) Notwithstanding anything to the contrary in this Drilling Contract (but subject always to Section 17.3), the rig construction contract for the Rig, or the procurement contracts for the BOPs, neither the exercise nor the non-exercise (nor anything done or not done in the exercise or non-exercise) by Operator of any respective right to monitor the Rig or her construction, or the BOPs or their construction, or any right of inspection or attendance or otherwise (including the receipt and review of any plans, drawings or instruction manuals relating to the Rig or any parts thereof, including the BOPs) in relation thereto shall (i) create or impose any obligation or liability whatsoever on any member of Operator Group with respect to the Rig or her construction, or the BOPs or their construction, (ii) in any way affect or alter Operator’s obligations or liabilities under this Drilling Contract, or (iii) in any way affect Contractor’s responsibility and liability under this Drilling Contract; provided, however, that Operator agrees to keep any such plans, drawings and manuals confidential in accordance with Section 17.3.

2.2 Arrival of Rig on Location

(a) Rowan Gibraltar intends to take delivery of the Rig ex-Builder’s yard in South Korea on or about October 31, 2014. Contractor shall then cause the mobilization of the Rig to the Area of Operations. No later than seven (7) days after the Effective Date, Contractor, Novatee and Operator shall execute and deliver the Deed of Novation, to be effective as of the date of the Rig’s arrival in the Area of Operations, assigning and transferring specified Contractor’s rights, obligations and liabilities under this Drilling Contract in respect of the Work to be performed in the Area of Operations to Novatee. Contractor shall obtain and maintain, and cause Novatee to obtain and maintain, any permits, approvals and authorizations from Governmental Authorities necessary or desirable to import the Rig into, and export the Rig out of, the Area of Operations and to move and operate the Rig within the Area of Operations which are to be obtained by Contractor in its name and by Novatee in its name under applicable laws, rules and regulations.

(b) Contractor shall provide the Rig to Operator, at the Operator’s designated location in the Area of Operations, in Rig Ready Condition, and ready to commence the Rig load-out on or after December 1, 2014 (the “Earliest Acceptance Date”), but on or before August 1, 2015 (the “Latest Delivery Date”), unless otherwise mutually agreed by the Parties in writing. The Latest Delivery Date shall be extended for documented periods of Force Majeure, delays caused solely by Operator Group, and changes to the Rig requested by Operator.

(c) After the Rig has arrived in the Area of Operations and is presented in Rig Ready Condition, Contractor shall conduct the Rig load-out (the “Load-Out Period”) at a suitable location within the Area of Operations determined by Operator in its sole discretion. The Load-Out Period shall be no longer than [***] days, unless extended by Operator in its sole discretion. Contractor shall be paid the Standby Rate for each day during the Load-Out Period; provided that Contractor does not cause any interruption to or suspension of the Rig load-out, in which case the Zero Rate shall apply during any such interruption or suspension.

(d) After the Load-Out Period is complete, Operator shall have [***] days (the “Rig Acceptance Period”) to perform the Rig Acceptance Testing. The Rig Acceptance Testing will be conducted at a suitable location within the Area of Operations determined by Operator in its sole discretion. Contractor shall provide Operator’s representatives with all access rights to the Rig and her equipment necessary for Operator to conduct the Rig Acceptance Testing. Contractor shall be paid the Zero Rate for each day of the Rig Acceptance Period. If Operator fails to complete the Rig Acceptance Testing during the Rig Acceptance Period, Contractor shall be paid the Standby Rate for such additional time Operator requires to complete the Rig Acceptance Testing; provided that if (i) Operator has not received sufficient access to the Rig or her equipment to conduct the Rig Acceptance Testing, or (ii) Contractor fails to assist Operator as necessary to

complete the Rig Acceptance Testing, or otherwise causes any undue delay or hindrance to the Rig Acceptance Testing, then Contractor shall receive the Zero Rate during the period that the Rig Acceptance Testing has been delayed due to any such delay or hindrance. Operator shall notify Contractor as soon as reasonably practical of each Critical Item and Non-critical Item that requires repair or remediation by Contractor. All repairs and remediation for Critical Items shall be at Contractor’s cost. Prior to the Term Commencement Date, Contractor shall repair or remediate all Critical Items to the Specifications and prepare a plan to repair or remediate all Non-critical Items to the Specifications. For the avoidance of doubt, prior to the Term Commencement Date, Contractor shall be paid the Standby Rate only during (x) the Load-Out Period, in accordance with Section 2.2(c), and (y) any such time in excess of the Rig Acceptance Period if Operator fails to complete the Rig Acceptance Testing during the Rig Acceptance Period for reasons other than those stated in Section 2.2(d)(i) and (ii) above. Subject to the foregoing and without prejudice to payment of the Mobilization Fee pursuant to Section 2.7(a), Contractor shall be paid the Zero Rate at all other times prior to the Term Commencement Date, including the time required to repair or remediate Critical Items to the Specifications and prepare a plan to repair or remediate Non-critical Items to the Specifications. To the extent practicable, Operator agrees to conduct certain aspects of the Rig Acceptance Testing during the trials and testing to be carried out by Builder and Rowan Gibraltar in conjunction with Rowan Gibraltar’s acceptance of the Rig from Builder.

(e) Delay in Arrival

(i) Should the Rig not arrive and be in Rig Ready Condition at the Operator’s designated location in the Area of Operations on or before the Latest Delivery Date, Operator will have the right to terminate this Drilling Contract in accordance with Section 13.2(c) at any time thereafter; provided, however, that Operator’s right to terminate pursuant to this Section 2.2(e)(i) shall expire (if not previously exercised) upon the Rig’s arrival and presentment in Rig Ready Condition at the Operator’s designated location in the Area of Operations. If the Rig has not arrived and been presented in Rig Ready Condition at the Operator’s designated location in the Area of Operations on or before May 1, 2015 (which date shall be extended for documented periods of Force Majeure, delays caused solely by Operator Group, and changes to the Rig requested by Operator), then for each period of seven (7) days thereafter until the Term Commencement Date, Contractor shall grant Operator one (1) free Rig day when the Operating Rate would otherwise apply following the Term Commencement Date (any such free Rig days, collectively, the “Delay Damages”). The Parties agree that Delay Damages are not a penalty and shall apply as a limitation on Contractor’s liability for failure of the Rig to

arrive and be in Rig Ready Condition at the Operator’s designated location in the Area of Operations on or before May 1, 2015 (as may be extended pursuant to this Section 2.2(e)(i)), regardless of fault. The Parties hereby acknowledge and agree that the amounts fixed pursuant to this Section 2.2(e)(i) are a genuine and reasonable estimation of the losses and damages that Operator will incur in the event of Contractor’s failure to procure the Rig’s arrival and presentment in Rig Ready Condition at the Operator’s designated location in the Area of Operations on or before May 1, 2015 (as may be extended pursuant to this Section 2.2(e)(i)) in accordance with this Drilling Contract. If such provisions (or any part thereof) in this Section 2.2(e)(i) are found for any reason to be void, invalid or otherwise inoperative, such provisions (or any part thereof) shall be deleted from this Drilling Contract and the balance of this Drilling Contract shall remain in full force and effect. Without prejudice to the foregoing, in such an event Contractor shall be liable for damages at law for any failure to comply with its obligations to procure the Rig’s arrival and presentment in Rig Ready Condition at the Operator’s designated location in the Area of Operations on or before May 1, 2015 (as may be extended pursuant to this Section 2.2(e)(i)) in accordance with this Drilling Contract; provided that such damages shall, regardless of fault, be limited to the amount which would have been payable had these provisions (or part thereof) in this Section not been void, invalid or otherwise inoperative.

(ii) Should Operator terminate this Drilling Contract pursuant to Section 2.2(e)(i), then such termination shall be the sole and exclusive remedy of Operator under this Drilling Contract for such delay in delivery.

(iii) Contractor’s delivery and provision of the Rig to Operator in accordance with Section 2.2(b) is a condition of this Drilling Contract and a fundamental obligation of Contractor and, except as expressly provided in this Drilling Contract, Contractor shall not be excused from performance of its obligations in Section 2.2(b) for any reason whatsoever.

Except with respect to the liabilities assumed by Contractor under Section 8.8(a), Operator shall assume all responsibility for and shall protect, indemnify, defend, release and hold harmless Contractor Group from and against all Claims, including Claims of Third Parties, regardless of fault, (including Claims for the cost of control, clean-up, removal, restoration and remediation) caused by contamination (including radioactive contamination) or pollution, including fines or penalties directly assessed against Operator and levied by any Governmental Authority, from:

(i) the discharge, disposal, release or escape of oil emulsion, oil based or chemically treated drilling fluids, contaminated cuttings, lost circulation and fish recovery materials and fluids not in the possession and control of any member of Contractor Group, including mud returns before the drilling solids treatment equipment; and

(ii) fire, blowout, cratering, seepage or any other uncontrolled flow of oil, gas, water or other substance emanating from a well or a reservoir.

The assumptions of liability by Operator under this Section 8.8(b) do not apply to loss or destruction of, or damage to, the property of, or injuries to or death of, any member of Operator Group or Contractor Group caused by such contamination or pollution, and shall, in no event, alter, lessen, or affect the liabilities or responsibilities of Operator specified in Sections 8.4, 8.5, 8.6, 8.7, 8.10 and 8.14 herein.

Without relieving Contractor of any of its obligations herein provided, the Parties agree that Operator may take part, to any extent it deems necessary, in the control and removal of any contamination or pollution which is the responsibility of Contractor under the foregoing provisions; and Contractor shall reimburse

Operator for the reasonable and customary documented cost thereof, subject to any limitation above provided, within thirty (30) days of receipt of a statement from Operator.

(d) Oilfield Waste Handling Procedure

Contractor shall comply with all applicable laws, rules and regulations regarding the handling of oilfield waste for which it is responsible pursuant to the HSSE Bridging Agreement. Contractor shall be responsible for used engine oil, oil filters, empty drums and hazardous waste generated by its operations, including without limitation, the proper handling of the used oil and the manifesting, reclaiming/recycling or disposal of the oil. The oil is to be transported in U.S. Coast Guard approved containers, not in used drums. Used drums are to be empty per specifications of the U.S. Department of Transportation, properly labeled, and have bungs in place prior to shipping to shore. Contractor will pick up and properly recycle or dispose of the empty drums. Oil filters, after being totally and properly drained, shall be disposed of as trash. Without prejudice to this Section 8.8, including without limitation, Operator’s indemnity obligation in Section 8.8(b) above, Contractor shall release, defend, indemnify and hold harmless Operator Group from any penalties or fines directly assessed against Contractor resulting from Contractor’s failure to comply with the obligations it has expressly assumed in this Section 8.8(d). Except as expressly assumed by Contractor in this Section 8.8(d), Operator assumes sole responsibility for the transport and disposal of all other waste as required in the HSSE Bridging Agreement, and Operator shall defend, indemnify and hold harmless Contractor Group from and against any penalties or fines directly assessed against Operator resulting from Operator’s failure to comply with its obligations in this Section 8.8(d). Notwithstanding anything to the contrary set forth elsewhere in this Drilling Contract, Contractor shall be solely responsible for obtaining coverage (including, but not limited to, submitting the Notice of Intent (“NOI”) and supplemental NOI) and complying with all applicable requirements of the National Pollutant Discharge Elimination System permit, including but not limited to all regulated discharges from the Rig such as the cooling water intake structure, maintenance wastes such as blasting and painting, deck drainage and domestic/consumer waste.

8.9 Contractor Indemnification — Personnel

Contractor shall protect, defend, indemnify, release and hold harmless Operator Group from and against all Claims for bodily injury, illness, disease, or death of any member of Contractor Group, regardless of fault; provided, however, that Contractor’s obligation to indemnify and hold harmless Operator’s other contractors providing helicopter services from and against all Claims for any loss or destruction of, or damage to, the property of Contractor Group shall exclude such Claims to the extent caused by the negligence or fault of such helicopter service providers (except where Operator’s

contract with its helicopter service provider requires Operator to indemnify such helicopter service provider for any loss or destruction of, or damage to, the property of Contractor Group, then the full terms of the indemnity in this Section 8.9 shall apply).

8.10 Operator Indemnification — Personnel

Operator shall protect, defend, indemnify, release and hold harmless Contractor Group and Builder from and against all Claims for bodily injury, illness, disease, or death of any member of Operator Group, regardless of fault.

8.11 Personnel and Property of Third Parties

(a) Subject to Sections 8.7, 8.8 and 8.15, Contractor shall protect, defend, indemnify, release and hold harmless Operator Group from and against all Claims (including those for bodily injury, personal injury, illness, disease, maintenance, cure, loss of consortium, loss of support, death, property damage, and wrongful termination of employment) by or in favor of or incurred or sustained by any Third Party, directly or indirectly arising out of, or incident to or in connection with this Drilling Contract, or the performance or non-performance of the Work (including without limitation Work involving ingress and egress, loading and unloading, presence on any platform, vessel, aircraft or other premises leased, chartered, owned, provided or rented by any Party), or any obligation under this Drilling Contract, to the extent such Claim is the result of the negligence (whether sole, joint, or concurrent), Gross Negligence, strict liability, Willful Misconduct, or other legal fault or breach of legal duty of any member of Contractor Group.

(b) Subject to Sections 8.7, 8.8 and 8.15, Operator shall protect, defend, indemnify, release and hold harmless Contractor Group from and against all Claims (including those for bodily injury, personal injury, illness, disease, maintenance, cure, loss of consortium, loss of support, death, property damage, and wrongful termination of employment) by or in favor of or incurred or sustained by any Third Party, directly or indirectly arising out of, or incident to or in connection with this Drilling Contract, or the performance or non-performance of the Work (including without limitation Work involving ingress and egress, loading and unloading, presence on any platform, vessel, aircraft or other premises leased, chartered, owned, provided or rented by any Party), or any obligation under this Drilling Contract, to the extent such Claim is the result of the negligence (whether sole, joint, or concurrent), Gross Negligence, strict liability, Willful Misconduct, or other legal fault or breach of legal duty of any member of Operator Group.

8.12 Gross Negligence

Notwithstanding anything in this Drilling Contract to the contrary, where Operator is required to protect, defend, indemnify, release and hold harmless Contractor Group from and against any Claims pursuant to the provisions of Sections 8.6 and/or 8.8(b), Contractor shall be responsible for and protect, defend, indemnify, release and hold harmless Operator Group from and against all such Claims to the extent caused by the Gross Negligence of any member of Contractor Group, up to a total amount of Fifty Million Dollars ($50,000,000) in the annual aggregate (and including, in relation to Claims pursuant to the provisions of Section 8.6, an amount equal to (x) the difference between the Operating Rate and the reduced day rate set out in Section 8.6, multiplied by (y) the number of days in respect of Section 8.6 applied in the event of such Gross Negligence).

8.13 Consequential Damages

Notwithstanding anything in this Drilling Contract to the contrary (excepting Section 8.1(c)), each Party shall at all times be responsible for and protect, defend, indemnify, release, and hold harmless the other Party from and against the Party’s own (and its respective Group’s) Consequential Damages suffered in connection with this Drilling Contract, regardless of fault. “Consequential Damages” means (i) special, indirect or consequential losses and damages, and (ii) whether direct or indirect, any and all loss and/or deferral or diminution of or the benefit of profit or revenue; loss of profit or revenue resulting from business interruptions; overheads, loss of or delay in production; loss of or damage to the leasehold, concession, production sharing contract or other similar rights; loss of or delay in drilling or operating rights; Operator’s spread costs (including hire and other charges payable to owners of vessels or suppliers of equipment or services and the costs of keeping vessels and equipment on location); or the cost of hiring a replacement rig; in each case whether or not foreseeable or disclosed at inception of this Drilling Contract; provided always that Consequential Damages shall never be construed as including (x) compensation due and payable to Contractor pursuant to this Drilling Contract, including termination payments pursuant to Section 13.3, and (y) any damages suffered or incurred by Operator arising or resulting from Contractor’s breach in repudiation of this Drilling Contract to contract the Rig with another customer.

8.14 Debris and Wreck Removal

Contractor shall promptly remove all debris and/or wreckage of the Rig or other Contractor’s Items to the extent compulsorily required by legally constituted authority. Contractor shall protect, defend, indemnify, release and hold harmless Operator Group for the costs of removal of such debris and/or wreckage and from and against Claims arising out of Contractor’s obligation to remove said debris and/or wreckage as described above, regardless of fault.

If any debris and/or wreckage of the Rig is not compulsorily required by legally constituted authority, but constitutes an impediment or interference to any operations of Operator (in Operator’s sole reasonable opinion), then Contractor shall remove such

debris and/or wreckage at Operator’s written request. In the event of such request, Contractor’s responsibility and liability shall not in any event exceed Fifty Million Dollars ($50,000,000), and Operator shall be responsible for and shall protect, defend, indemnify, release and hold harmless Contractor Group from and against all Claims arising out of the removal of any such debris and/or wreckage of the Rig in excess of such amount.

8.15 Patent Infringement

(a) Contractor hereby represents to Operator Group that any and all tools, equipment, and services which may be used, constructed, or provided by Contractor Group hereunder, do not, to the best of Contractor’s knowledge, infringe any patent, copyright, or trademark or misappropriate any trade secrets, and with respect to any such tools, equipment, and services which are used, constructed, or so provided, Contractor shall protect, defend, indemnify, release and hold harmless Operator Group from and against any and all Claims, made by a claimant with regard thereto. Operator hereby represents to Contractor Group that any and all tools, equipment, and services which may be used, constructed, or provided by Operator Group hereunder, do not, to the best of Operator’s knowledge, infringe any patent, copyright, or trademark or misappropriate any trade secrets, and with respect to any such tools, equipment, and services which are used, constructed, or so provided, Operator shall protect, defend, indemnify, release and hold harmless Contractor Group from and against any and all Claims, made by a claimant with regard thereto.

(b) The Rig to be provided pursuant to this Drilling Contract will have a primary and an auxiliary drill center. Operator acknowledges that some potential uses of two drill centers may relate to the claims of Transocean’s United States Patent Nos. 6,085,851, 6,068,069, 6,056,071, and 6,047,781 and related Transocean patents in other jurisdictions (“Transocean’s dual-activity patents”). Notwithstanding any provision to the contrary, Contractor will not deliver the Rig to Operator in a condition that would infringe the valid and enforceable claims of Transocean’s dual-activity patents, if any, in effect in the jurisdiction(s) in which the Rig is contracted to Work, unless Contractor obtains a license from Transocean to operate in such jurisdiction(s), as described further below. Operator acknowledges that it may be necessary to install a “casing sleeve” in the auxiliary drill center or otherwise limit the capabilities of the Rig in order to avoid the coverage of Transocean’s dual-activity patents in the jurisdiction(s) in which the Rig is contracted to perform the Work, and that such casing sleeve or other limitations may be required to remain in place during certain operations unless the Work is performed in a jurisdiction which is not covered by Transocean’s dual-activity patents or where Transocean’s dual-activity patents are no longer in force. In the event that Operator desires to receive the Rig or use the Rig in a manner that would infringe upon Transocean’s dual-activity patents, Operator understands that it will be required to obtain a license from Transocean, and the Parties will

use commercially reasonable efforts to obtain such license. If Operator desires Contractor to enable the dual activity capability of the Rig, such dual activity shall only be enabled on the basis of the Parties entering into a written agreement that provides for the payment by Operator of (i) all costs incurred to enable the dual activity and (ii) all on-going royalties payable by Contractor under the patent license agreement from and after the date that such dual activity is activated, regardless of whether or not Operator discontinues the use of the dual activity after it is enabled. For the purpose of this Drilling Contract, “dual activity” shall be defined as a rig that has a ▇▇▇▇▇▇▇ or superstructure supporting two well centers, both of which are capable of running tubulars to the seabed.

8.16 Right to Participate in Defense

The indemnifying Party shall, at its sole cost and expense, investigate, handle, respond to and provide defense for any Claim for which it gives indemnity herein, provided that, at its expense, the Party being indemnified shall be afforded the right and opportunity to participate in any such investigation, defense or litigation regarding a Claim for which it is indemnified through counsel of its own choosing.

8.17 Attorneys’ Fees to Enforce Contract

In the event a Party, after receipt of notice of a Claim, fails to furnish a defense and indemnity as provided for herein or in the event either Party breaches an obligation in this Drilling Contract, the other Party shall be entitled to receive from the offending Party reasonable attorneys’ fees, costs, and expenses incurred in the enforcement of this Drilling Contract, including Claims for contractual indemnity and insurance coverage.

8.18 Taxes

(a) Except as provided herein, each Party shall be responsible for any taxes imposed on such Party by any Governmental Authority.

(b) If Operator requests Contractor to perform Work in state or territorial waters, other than as contemplated by this Drilling Contract, Operator shall assume all responsibility for and shall protect, defend, indemnify, release and hold harmless Contractor Group and the Rig from and against all Claims for any State, County or Parish, and/or other municipal or local tax or similar levy and attendant costs and expenses which may be applicable to or arise from operations or revenues earned by Contractor under this Drilling Contract, including the Rig and other Contractor’s Items; provided, however, that Contractor shall take all commercially reasonable steps to minimize any such taxes, and any reimbursement, indemnification or other payment made by Operator pursuant to this Section 8.18(b) shall be reduced to the extent that such Claim would result in a tax benefit to Contractor. Contractor shall notify Operator if (i) Contractor anticipates that a request made by Operator will result in taxes (and the extent of

such taxes) described in the preceding sentence, or (ii) any member of Contractor Group receives a notice from any Governmental Authority with regard to any such taxes. Contractor shall cooperate fully with Operator and Operator’s representatives at Operator’s expense should Operator choose to contest any such tax or levy.

(c) Except as otherwise provided in Section 3.3(c)(i) and Section 8.18(b), Contractor shall assume all responsibility for and shall protect, defend, indemnify, release and hold harmless Operator Group from and against all Claims relating to:

(i) all taxes, duties, levies, charges and contributions (and any interest or penalties thereon) for which Contractor (or any subcontractor or any other Person employed by Contractor or providing services relating to or in connection with this Drilling Contract to Contractor) is liable as imposed by any Governmental Authority; and

(ii) any statutory obligation imposed on Contractor (or any subcontractor or any other Person employed by Contractor or providing services relating to or in connection with this Drilling Contract to Contractor) to make deductions on account of tax and remit the required amounts to any Governmental Authority, including, but not limited to, income tax, national insurance, employee taxes, charges, social security costs, levies and contributions, whether or not they are measured by the wages, salaries or other remuneration or benefits paid to Persons employed by Contractor or providing services relating to or in connection with this Drilling Contract to Contractor.

(d) Operator shall assume all responsibility for and shall protect, defend, indemnify, release and hold harmless Contractor Group from and against all Claims relating to:

(i) all taxes, duties, levies, charges and contributions (and any interest or penalties thereon) for which Operator (or any subcontractor or any other Person employed by Operator or providing services relating to or in connection with this Drilling Contract to Operator, excluding any member of Contractor Group) is liable as imposed by any Governmental Authority; and

(ii) any statutory obligation imposed on Operator (or any subcontractor or any other Person employed by Operator or providing services relating to or in connection with this Drilling Contract to Operator, excluding any member of Contractor Group) to make deductions on account of tax and remit the required amounts to any Governmental Authority, including, but not limited to, income tax, national insurance, employee taxes, charges, social

security costs, levies and contributions, whether or not they are measured by the wages, salaries or other remuneration or benefits paid to Persons (excluding any member of Contractor Group) employed by Operator or providing services relating to or in connection with this Drilling Contract to Operator.

8.19 Liens

Contractor shall keep Operator’s Items, the well(s), licenses and interest therein or production therefrom and the Work free and clear of all liens, claims, assessments, fines and levies created or committed by Contractor or by subcontractors or contractors of Contractor; provided that Operator makes payments of all liquidated and undisputed amounts due Contractor in accordance with Article IV (failing which Contractor may have the right to assert a lien against Operator’s Items, the well(s), licenses or interests therein or production therefrom or the Work, but only to the extent of any liquidated and undisputed amounts then past-due and payable by Operator hereunder). Operator may, subject to the prior written approval of Contractor, post on Contractor’s Items such notices as Operator and Contractor may mutually agree in order to ensure the reasonable protection of Operator against any liens, claims, assessments, fines and/or levies upon Operator’s assets. In the event any such liens are improperly filed by Contractor, its subcontractor or contractors against Operator or any of its ▇▇▇▇▇, property or equipment, Contractor shall assume all responsibility for and shall protect, defend, indemnify, release and hold harmless Operator Group from and against all Claims relating thereto.

ARTICLE IX
INSURANCE

9.1 Contractor’s Insurance

To support its indemnification obligations in this Drilling Contract, but as a separate and independent obligation, Contractor agrees to procure and maintain throughout the term of this Drilling Contract, at its sole cost and expense, insurance coverages of the type and in the amounts (through insurance, including self-insured retentions and/or deductibles in reasonable amounts consistent with customary industry practice) set forth in Appendix E, Part A.

(a) The indemnity obligations of Contractor, as set out in this Drilling Contract, are independent of any insurance requirements as set out in Article IX and Appendix E, Part A, and such indemnity obligations shall not be lessened or extinguished by reason of Contractor’s failure to obtain the required insurance coverage or by any defenses asserted by Contractor’s insurers. Moreover, the indemnity obligations of Operator, as set out in this Drilling Contract, are independent of any insurance requirements as set out in Article IX and Appendix E, Part B, and such indemnity obligations shall not be lessened or extinguished by reason of Operator’s failure to obtain the required insurance coverage or by any defenses asserted by Operator’s insurers.

(b) In the event that this Drilling Contract is interpreted under the laws of the State of Texas for a particular occurrence, then Article VIII shall apply, but for the purposes of Title 6, Chapter 127 of the Texas Civil Practice and Remedies Code, commonly known as the Texas Oilfield Anti-Indemnity Act, the indemnity and insurance provisions of this Drilling Contract applicable to property damage and the indemnity and insurance provisions applicable to personal injury, bodily injury, and death shall be deemed separate for interpretation, enforcement, and other purposes. If the laws of the State of Texas govern this Drilling Contract, then the Parties incorporate Title 6, Chapter 127 of the Texas Civil Practice and Remedies Code, and agree to the limits of that statute.

(c) In the event that this Drilling Contract is interpreted under the laws of the State of Louisiana for a particular occurrence, then Article VIII shall apply, but for the purposes of LA. R.S. 9:2780, commonly known as the Louisiana Oilfield Anti-Indemnity Act, the indemnity and insurance provisions of this Drilling Contract applicable to personal injury, bodily injury, and death shall be deemed separate for interpretation, enforcement, and other purposes. If the laws of the State of Louisiana govern this Agreement, then the Parties incorporate La. R.S. 9:2780 and agree to the limits of that statute.

9.4 Subcontractors

Contractor shall use all commercially reasonable efforts to cause its subcontractors to obtain, maintain and keep in force during the time in which they are performing services hereunder, insurance deemed necessary to cover the Work, and furnish Operator evidence of such insurance coverage upon request.

ARTICLE X
INDEPENDENT CONTRACTOR

10.1 It is expressly understood that Contractor is an independent contractor and neither Contractor, its contractors or subcontractors, nor any of their respective employees, representatives, or agents, are or shall be employees, representatives, or agents of Operator. The actual performance and superintendence of all Work hereunder shall be by Contractor, under the control and direction of Contractor, as to the details of the Work and Contractor shall take responsibility for the adequacy, stability and safety of all of its operations and methods necessary for the performance of the Work; provided, however, that Operator, being interested in the results to be obtained, is authorized to designate a representative or representatives who shall at all times have access to the Rig and related equipment for the purposes of observing tests or inspecting the Work performed hereunder by Contractor in furtherance of its interest.

ARTICLE XI
GOVERNING LAW AND DISPUTE RESOLUTION

11.1 This Drilling Contract (and all non-contractual obligations which may arise out of or in connection with it) shall be governed by and construed in accordance with the laws of England, not including any of its conflicts of law rules that would direct or refer to the laws of another jurisdiction. The Parties have allocated liability risk pursuant to this Drilling Contract and therefore intend and agree that no anti-indemnity law, rule or regulation apply hereto.

11.2 In the event of a dispute between the Parties hereto, including a commercial dispute or a dispute connected with a personal injury or property damage claim, disputes as to its existence, validity or termination or the consequences of its nullity, and disputes relating

to non-contractual obligations, arising out of or relating to this Drilling Contract, or the breach thereof, then:

(a) the Parties agree that Operator’s Chief Operating Officer and Contractor’s President or Chief Operating Officer, or their respective designees, will promptly consult and negotiate with each other and, recognizing their mutual interests, attempt to reach a prompt, just and equitable resolution satisfactory to the Parties;

(b) if no resolution satisfactory to the Parties has been reached within three (3) business days, either Party may make a written demand to submit the dispute to non-binding mediation. Such mediation shall be conducted at Houston, Texas, in an expedited manner by a mediator jointly appointed and agreed to by the Parties; and

(c) in the event the Parties are unable to resolve their dispute through mediation pursuant to Section 11.2(b), within thirty (30) days from the failure to reach a satisfactory resolution pursuant to Section 11.2(a), such dispute shall be settled exclusively and finally by arbitration under the Arbitration Rules of the London Court of International Arbitration (“LCIA”) current at the time when the arbitration proceedings are commenced, which rules are deemed to be incorporated by reference into this Article XI. There shall be three (3) arbitrators, one nominated by the claimant Party, one nominated by the respondent Party within fourteen (14) days of the claimant Party’s nomination, and one nominated by the two Party-nominated arbitrators. If the two arbitrators fail to agree on the nomination of the third arbitrator within ten (10) days of the nomination of the respondent Party’s arbitrator, the LCIA Court shall make such appointment only. The inclusion of such nomination mechanism shall not exclude the powers of the LCIA Court under Article 9 of the LCIA Rules. Article 13.1 of the LCIA Rules shall be disapplied to the extent that each Party may communicate (without copy to any other Party) with its nominated arbitrator regarding the nomination of the chairman only, up until such time as agreement is reached on the nomination of the chairman. The seat and place of the arbitration shall be London, England. The language to be used in the arbitration shall be English. All arbitration notices and requests for arbitration shall be deemed properly given if sent in accordance with Section 15.1.

11.3 Any award shall be final and binding on the Parties and may be confirmed in, and judgment upon the award entered by, any court having jurisdiction.

11.4 Reference to specific articles of the LCIA Rules in this clause are references to the 1998 edition of such rules — should a subsequent edition of such rules be in force at the time any arbitration is commenced hereunder, then the references to specific articles should be updated mutatis mutandis to achieve the same result.

11.5 In any mediation or other legal proceeding arising out of or relating to this Drilling Contract, each Party agrees that all exemplary and punitive damages are expressly waived, except to the extent the same may be included in any Claim by a Third Party.

ARTICLE XII
FORCE MAJEURE

12.1 (a) A Party shall not be in default of its obligations hereunder to the extent its delay in performance results from an event of Force Majeure; provided that the Party affected by the Force Majeure uses all commercially reasonable efforts to: (i) proceed with its obligations under this Drilling Contract to the extent that it is not prevented from doing so by the event of Force Majeure; (ii) remove or relieve any event of Force Majeure and its consequences and minimize the effects of the delay caused thereby; and (iii) resume performance as soon as practicable after the event of Force Majeure. The occurrence of an event of Force Majeure shall not relieve the affected Party of its obligations to mitigate the effects thereof.

(b) Each Party shall exercise reasonable diligence to overcome any Force Majeure delaying the Work herein but shall not be obligated to settle any labor dispute except on terms acceptable to it and all such disputes shall be handled within the sole discretion of the affected Party. Notwithstanding anything to the contrary in this Drilling Contract, the Force Majeure Rate shall not be applicable until the Rig has arrived in the Area of Operations.

(c) The Force Majeure Rate shall be payable to Contractor during any period in which the Work is not being performed because of Force Majeure up to a maximum number of [***] consecutive days per occurrence. Following the expiry of such [***] day period, the Standby Rate shall apply until the earliest of such time as (i) this Drilling Contract is terminated in accordance with Article XIII (provided that Operator shall use commercially reasonable endeavours to procure a new Area of Operations before exercising its termination right pursuant to Section 13.2(b)), or (ii) the Rig commences mobilization to a new Area of Operations in accordance with a new agreement pursuant to Section 3.2, or (iii) the Force Majeure condition is abated.

ARTICLE XIII
TERMINATION

13.1 Termination Conditions for Contractor

(a) Subject to the provisions of Article IV, in the event that any liquidated and undisputed payments due by Operator are not paid when due, Contractor shall notify Operator of nonpayment and shall give Operator ten (10) days from receipt of said notice to pay amounts due with applicable interest. In the event Operator fails to pay within the said ten (10) day period, Contractor may terminate this

Drilling Contract by notifying Operator in writing to that effect and this Drilling Contract shall terminate fifteen (15) days after receipt of the notice unless payment with interest, of all invoices then overdue and not in dispute is received by Contractor prior to the expiration of said fifteen (15) day period. In this instance, Contractor shall not be obligated to finish any well or Work in progress by Operator, but shall be obligated to perform such further Work as may reasonably be required to secure the well in accordance with Good Industry Practices and all applicable laws, rules and regulations, in which case, the aforesaid termination shall be effective upon completion of such Work.

(b) This Drilling Contract shall terminate upon total loss or constructive total loss of the Rig.

(c) In the event of Operator becoming bankrupt or making a composition or arrangement with its creditors, or of a winding-up order of Operator being made, or (except for the purposes of amalgamation or reconstruction) a resolution for its voluntary winding-up being passed, or a receiver or other officer with like powers being appointed for Operator or any of its properties or assets, or should any equivalent act or thing be done or suffered under any applicable laws, this Drilling Contract shall terminate. In the event of termination under this Section 13.1(c), Contractor shall be entitled to payment of the Early Termination Fee under Section 13.3(a).

ARTICLE XVIII
GENERAL

18.1 This Drilling Contract has been jointly drafted by Operator and Contractor, and no portion of this Drilling Contract shall be construed against Operator or Contractor on the ground that Operator or Contractor supplied, amended, or deleted such portion or any other portion hereof. However, the obligations, undertakings, representations and warranties in the “Whereas” clauses of this Drilling Contract shall be considered as fully enforceable.

18.2 It is expressly understood that Contractor is an independent contractor and none of Contractor, its contractors and subcontractors, and any of their respective employees, representatives and agents, are or shall be employees, representatives or agents of Operator. As an independent contractor, neither Contractor nor anyone employed by Contractor will be eligible for the benefits provided to regular employees of Operator, including health and disability insurance. The actual performance and superintendence of all Work hereunder shall be by Contractor, under the control and direction of Contractor, as to the details of the Work and Contractor shall take responsibility for the adequacy, stability and safety of all of its operations and methods necessary for the performance of the Work; provided, however, that Operator, being interested in the results to be obtained, is authorized to designate a representative or representatives who shall at all times have

access to the Rig and related equipment for the purposes of observing tests or inspecting the Work performed hereunder by Contractor in furtherance of its interest.

18.3 This Drilling Contract, including the Appendices, constitutes the entire agreement of the Parties. Each Party agrees that in entering into this Drilling Contract and the documents referred to therein, such Party is not relying on, and shall have no remedy in respect of, any statements, warranties, or representations given or made (whether negligently or innocently and whether express or implied), which are not expressly set out in this Drilling Contract. Nothing in this Section 18.3 operates to limit or exclude any liability for fraud. In the event of a conflict between the Appendices, on the one hand, and the body of this Drilling Contract, on the other, the body of this Drilling Contract shall prevail.

18.4 If any portion of this Drilling Contract is declared by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any applicable laws, this Drilling Contract shall nevertheless continue in force and effect as to those provisions remaining valid. The waiver or forbearance of any right hereunder shall not preclude the insistence of such right thereafter in any instance.

18.5 In the event of conflict between any provision or term hereof and the provisions or terms of any invoice, bid, price list, manifest, job order or other document between the Parties, the provisions and terms hereof shall prevail.

18.6 No amendment hereto shall be effective unless contained in an instrument in writing executed by Operator and Contractor.

18.7 None of the terms and conditions of this Drilling Contract shall be considered to be waived by either Operator or Contractor unless a waiver is given in writing by one Party to the other. No failure on the part of either Party to enforce any of the terms and conditions of this Drilling Contract shall constitute a waiver of such terms. A waiver shall not be a continuing waiver unless expressly stated.

18.8 Notwithstanding anything to the contrary in this Drilling Contract, the provisions of Section 2.7(b), Article III, Article IV, Article VIII, Article IX, Article XI, Article XIII, Article XVII, and this Section 18.8 and any other provision of this Drilling Contract providing for payment of sums due and payable or accruing on or after the termination date of this Drilling Contract shall survive the termination of this Drilling Contract.

18.9 This Drilling Contract shall be binding upon and inure solely to the benefit of each Party and their successors, assigns and transferees.

18.10 Communications; Language

(a) All instructions, notices, agreements, authorizations, approvals and acknowledgements issued pursuant to, relating to or arising out of this Drilling

Contract shall be in writing. All such documentation, together with all correspondence and other documents, shall be in English.

(b) Notwithstanding the foregoing, if for any reason it is considered necessary by Operator to give an instruction to Contractor orally in the first instance, Contractor shall comply with such instruction. Any such oral instruction shall be confirmed in writing as soon as is possible under the circumstances; provided that if Contractor confirms in writing any such oral instruction which is not contradicted in writing by Operator without undue delay, it shall be deemed to be an instruction in writing by Operator.

18.11 The Parties agree that this Drilling Contract may be executed in counterparts, including fax counterparts, and together with all counterpart executions shall be considered an original for all purposes hereunder.

18.12 Third Party Rights

(a) Subject to subsection (c) hereof, the Parties intend that no provision of this Drilling Contract shall, by virtue of the Contracts (Rights of Third Parties) Act 1999 (the “Act”) confer any benefit on, nor be enforceable by, any Person who is not a party to this Drilling Contract.

(b) For the purpose of this Section 18.12, “Third Party” shall include any member of Operator Group or Contractor Group, but exclude Operator, Contractor, and their respective permitted assignees and novatees.

(c) Subject to the provisions of this Drilling Contract, Article VIII and Article IX are intended to be enforceable by a Third Party by virtue of the Act.

(d) Notwithstanding subsection (c) hereof, this Drilling Contract may be rescinded, amended or varied by the Parties without notice to or the consent of any Third Party even if, as a result, that Third Party’s right to enforce a term of this Drilling Contract may be varied or extinguished.

(e) In enforcing any right to which it is entitled by virtue of the Act and under the provisions of this Drilling Contract, the remedies of a Third Party shall be limited to damages only and such Third Party shall not be entitled to any other remedies available at law or otherwise.

(f) A Third Party shall not be entitled to assign any benefit or right conferred on it under this Drilling Contract.

APPENDIX A

RIG ACCEPTANCE AND PERFORMANCE CRITERIA

Contractor shall demonstrate that the Rig and all marine, drilling, subsea, emergency, and other systems are acceptable to Operator through a series of tests (hereinafter, collectively, the “Acceptance Tests”) to be established by Operator, with the agreement of Contractor, such agreement not to be unreasonably withheld. The Acceptance Tests will be designed to load test and/or pressure test all major components, function test components where appropriate, and perform other tests as required herein prior to Operator accepting the Rig (“Acceptance”) for the performance of the Work under the Drilling Contract. The time of Acceptance will be determined by an Acceptance Letter provided by Operator to Contractor. The Acceptance Letter shall include:

· The date of Acceptance of the Rig by Operator;

· Operator’s confirmation that the Rig has passed all pressure, load, and function tests; such tests to include, without limitation, those listed in Sections A through M of this Appendix A; and

· Operator’s confirmation that the Rig is acceptable for use by Operator for the Primary Term of the Drilling Contract.

Notwithstanding anything to the contrary in this Appendix A, the demonstration of the Acceptance Tests listed under Section B.2S BOP Stack Subsea Tests — Secondary BOP Stack shall not be a condition of Acceptance pursuant to this Appendix A and such Acceptance Tests shall be performed following Acceptance of the Rig by Operator. In the event the Rig fails such Acceptance Tests listed under Section B.2S BOP Stack Subsea Tests — Secondary BOP Stack, such failure shall be deemed to be an event constituting BOP Unavailability and the provisions of Appendix I, Section B(3) shall apply.
