7.2 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 Court within 15 days of the appointment of the second arbitrator.

Before an arbitrator has been appointed by a Relevant Finance Party to determine a Dispute, the Agent may (and, if so instructed by the Relevant Majority Lenders, shall) by notice in writing to the Borrower require that all Disputes or a specific Dispute be heard by a court of law.

8 JURISDICTION

8.1 Jurisdiction of English courts

To the extent allowed by law, the Relevant Finance Parties may take concurrent proceedings in any number of jurisdictions.

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.

8.3 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.
