PREMIUMS. Premium shall be payable as provided in Item 6 of the Declarations. Underwriters shall be subrogated to all rights which the Assured may have against any person or other entity, other than Principal Assureds and Other Assureds, in respect of any claim or payment made under Section I or Section II of the Policy. The Assured shall execute all papers required by the Underwriters and shall co-operate with the Underwriters to secure their subrogation rights. Underwriters agree to waive rights of subrogation against any Principal Assured(s) and/or Other Assured(s). The Assureds shall not grant any waiver of subrogation to drilling contractors and/or their sub-contractors without obtaining Underwriters’ agreement to a specific endorsement to this Policy prior to the commencement of operations. As a condition precedent to their benefiting from the automatic waiver of subrogation in this clause, Other Assureds must perform their operations according to Quality Assurance/Quality Control system(s) that comply with the Quality Assurance/Quality Control provisions passed on by the Principal Assureds through each and every written contract awarded within the scope of insured works as scheduled under the Policy. All values, limits, deductibles and premiums contained in the Policy are in respect of a 100% interest and shall be reduced in proportion to the individual Principal Assured(s) interest as declared or as may be subsequently declared and agreed by Underwriters. All clauses incorporated into the Policy by reference (hereinafter the “Incorporated Clauses”) apply insofar as they do not conflict with the wording of the Policy. In the event that the Incorporated Clauses conflict with this Policy wording, this wording shall take precedence. It is understood and agreed that the Policy shall be governed by English law and practice. Any dispute, controversy or claim arising out of or relating to the Policy shall be submitted to and determined by the courts of England and Wales, which shall have exclusive jurisdiction of all such matters. Whereas the Policy is issued in US dollars, it is agreed that, if any Assured so elects after acceptance of a claim by Underwriters but before settlement of the claim, Underwriters may effect payment in US dollars or sterling, at rate of exchange at the mid point of the closing rates between sterling and US dollars as published in the Financial Times two working days before payment is issued by Underwriters.
