9.2 Procedure for arbitration

(a) The arbitral tribunal shall consist of three arbitrators. The claimant(s), irrespective of number, shall nominate jointly one arbitrator; the respondent(s), irrespective of number, shall nominate jointly the second arbitrator; and a third arbitrator, who shall serve as chairman (who shall be a lawyer currently qualified in England and Wales and be admitted to the Bar of England and Wales), shall be appointed by the LCIA within 15 days of the appointment of the second arbitrator.

10 JURISDICTION

10.1 Jurisdiction of English courts

(a) The courts of England have exclusive jurisdiction to settle all Disputes.

(b) The Parties agree that the courts of England are the most appropriate and convenient courts to settle Disputes and accordingly no Party will argue to the contrary.

(c) This Clause 10.1 is for the benefit of the Finance Parties only. As a result, no Finance Party shall be prevented from taking proceedings relating to a Dispute in any other courts with jurisdiction. To the extent allowed by law, the Finance Parties may take concurrent proceedings in any number of jurisdictions.

10.2 Service of process

Without prejudice to any other mode of service allowed under any relevant law, the Borrower:

(b) agrees that failure by a process agent to notify it of the process will not invalidate the proceedings concerned.

10.3 Waiver of damages

In no event shall any Finance Party be liable on any theory of liability for any special, indirect, consequential or punitive damages and the Borrower hereby waives, releases and agrees (for itself and on behalf of its Subsidiaries) not to xxx upon any such claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favour.

10.4 Waiver of immunity

The Borrower irrevocably agrees that, should any party take any proceedings anywhere (whether for an injunction, specific performance, damages or otherwise), no immunity (to the extent that it may at any time exist, whether on the grounds of sovereignty or otherwise) from those proceedings, from attachment (whether in aid of execution, before judgment or otherwise) of its assets or from execution of judgment shall be claimed by it or on behalf of it or with respect to its assets, any such immunity being irrevocably waived.
