(b)                                 during any period after the Commencement Date (other than Mobilization or Demobilization) that the Drilling Unit is under tow, or under way.

705.         Standby Rate

The Standby Rate specified in Appendix A will be payable as follows:

16

(a)                                  during any period of delay when Contractor is unable to proceed because of adverse sea or weather conditions including but not limited to tropical disturbances, tropical depressions, tropical storms, hurricanes, and loop and eddy currents;

17

If operations are suspended as a result of breakdown or failure of Contractor’s Items to permit replacement, inspection, repair or maintenance of Contractor’s subsea equipment, the repair period shall commence and the Repair Rate of zero ($0) shall apply immediately upon such suspension of operations and shall cease when the BOP stack/LMRP has been rerun, latched, successfully tested and the BOP/LMRP test plug has been pulled to the surface.

707.         Force Majeure Rate

The Force Majeure Rate specified in Appendix A will be payable during any period in which operations are not being carried on because of Force Majeure as defined in Paragraph 1303, including periods required to repair damage caused by a Force Majeure event, up to a maximum of thirty (30) consecutive days, after which and during the continuous existence of the Force Majeure condition, no day rate will be payable and, subject to Paragraph 1303, the Contract may be terminated by either party upon written notice, subject to demobilization as provided in Paragraph 703; provided, however, that Operator may prevent such termination by continuing to pay the Force Majeure Rate.

1305.       Compliance with Laws

Each party hereto agrees to comply with all laws, rules and regulations of any federal, state or local government authority having jurisdiction over the Operating Area which are now or may become applicable to that party’s operations covered by or arising out of the performance of this

30

Contract.  In the event any provision of this Contract is inconsistent with or contrary to any applicable federal, state or local law, rule or regulation, said provision shall be deemed to be modified to the extent required to be consistent with said law, rule or regulation, and as so modified said provision and this Contract shall continue in full force and effect.

1306.       Waivers

It is fully understood and agreed that none of the requirements of this Contract shall be considered as waived by either party unless the same is done in writing, and then only by the persons executing this Contract, or other duly authorized agent or representative of the party.

1307.       Entire Agreement

This Contract supersedes and replaces any oral or written communications heretofore made between the parties relating to the subject matter hereof.

1309.       Conflicts of Interest

No director, employee or agent of Contractor or of any of its Affiliated Companies, or its or their subcontractors shall give to or receive from any director, employee or agent of Operator any commission, fee, rebate, or any gift or entertainment of significant cost or value in connection with the Work or this Contract, or enter into any business arrangement with any director, employee or agent of Operator other than as a representative of Operator, without prior written notification thereof to Operator. Contractor shall promptly notify Operator of any violation of this Paragraph 1309 and any consideration received as a result of such violation shall be paid over or credited to Operator.

In addition, Contractor shall comply with what is established in Law-Decree Nr. 17/09, of June 26 and the regulations, Law-Decree No. 127/03 of November 25 and the regulations, and all other applicable Angolan laws and regulations in respect of the local preference and employment and training of relevant personnel.

In performing the Work, Contractor shall:

(a)                                  contract with Angolan subcontractors as long as their performance is similar to that on the international market and the price of their services, when subject to the same tax charges, are no more than ten percent (10%) higher than the prices of international items, before Angolan customs duties, but after the respective costs of transportation and insurance have been included; and

This Contract shall be deemed a personal contract of Contractor and neither Contractor nor its underwriters shall be entitled to claim the benefits of any limitation of liability statute in respect of claims asserted by Operator or any member of Operator Group based on this Contract, whether under the Limitation of Liability Act, 46 U.S.C. App. Sections 181-189, or any other similar laws or treaties. The purpose of this provision is to insure by specific contractual agreement that Operator and the members of Operator Group are able to enforce all defense, release, indemnity, and insurance obligations and coverage for their benefit under this Contract without regard to any potential limitation of liability by Contractor. Subject to Contractor’s contractual obligations in this Contract, nothing in this provision is intended to prevent Contractor or its underwriters from asserting all applicable limitation of liability defenses against any tort claims by any person or entity.

1314.       Contracts (Rights of Third Parties) Act 1999

Operator and Contractor acknowledge that it is their intention to extend to those parties included in the definition of Operator Group and Contractor Group certain liability protection pursuant to the provisions of Paragraphs 606, 607 and 609 and Article IX of this Contract. 

32

However, except as provided in Paragraphs 606, 607 and 609 and Article IX of this Contract, a person or party who is not a party to this Contract (“other party”) shall have no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of the Contract (or any agreement amending the Contract or expressed to be supplemental hereto) notwithstanding that any such term may purport to confer or may be construed as conferring a benefit on such other party.

Notwithstanding the foregoing, Operator and Contractor may rescind and/or vary any of the terms of this Contract (including in respect of any relief from liability, hold harmless, indemnity or benefit given to any other party) without the consent of any party acquiring rights under this Paragraph 1314.

APPENDIX B

DRILLING UNIT AND EQUIPMENT TO BE PROVIDED BY CONTRACTOR

A.                    GENERAL DESCRIPTION

The Ocean Confidence is a deep-water self-propelled, dynamic positioned, semi-submersible drilling unit, which was built to operate in severe environment areas worldwide. Enhanced stability, structural strength, high performance and efficiency were Diamond Offshore’s guidelines in the development of this unit which includes the necessary winterization and deck load capacity to operate both in typical North Sea type environment conditions and in remote deep water areas for extended periods without constant logistic support. The Ocean Confidence has the capacity to drill to a depth of 35,000’ subject to the rated capacity of the equipment as specified in this Appendix B of the Contract.

B-1

NOTE: For locations in excess of 8,000 feet of water, Operator must provide Contractor with a minimum of three (3) months prior notice to ensure equipment availability, and such locations are subject to site-specific station keeping and riser analyses to determine limitations, if any.

B-2

Note that the above loads are individual maximum design loads for each area.  For details on allowable combined loadings, refer to the “Specification of Load Cases for Substructure Design”.

Quarters
