        	(b)	
                The Obligors accept that the courts of England are the most appropriate and convenient courts to settle Disputes and accordingly no Obligor will argue to the
                    contrary.

              


      

    

    
      
        	(c)	
                This Clause 9.1 (Jurisdiction) is for the benefit of
                    the Lender only.  As a result, the Lender shall not be prevented from taking proceedings relating to a Dispute in any other courts with jurisdiction.  To the extent allowed by law, the Lender may take concurrent proceedings in any
                    number of jurisdictions.

        	(a)	
                Without prejudice to any other mode of service allowed under any relevant law, each Obligor:

              


      

    

    
      
        	

              	(i)	
                irrevocably appoints Messrs. E.J.C Album Solicitors, presently of Landmark House, 190 Willifield Way, London, NW11 GY1, England (Attention of Mr. Eduard Album
                    Fax +44 (0) 20 8457 5558, e-mail: ejca@mitgr.com) as its agent for service of process in relation to any proceedings before the English courts
                    in connection with any Finance Document; and

              


      

    

    
      
        	

              	(ii)	
                agrees that failure by a process agent to notify the relevant Obligor of the process will not invalidate the proceedings concerned.

              


      

    

    
      
        	(b)	
                If any person appointed as an agent for service of process is unable for any reason to act as agent for service of process, the Borrower (on behalf of the
                    other Obligors) must immediately (and in any event within 14 days of such event taking place) appoint another agent on terms acceptable to the Lender.  Failing this, the Lender may appoint another agent for this purpose.
