         will be deemed duly served if in the case of one addressed to the
         Company it is sent by registered post or left at the Company's
         registered office, or in the case of one sent to the Vice President it
         is handed to him personally or is delivered to his last known
         residential address in the Cayman Islands. A notice sent by post will
         be deemed to be served on the third day following the date on which it

Previous Agreements Superseded

21       This Agreement supersedes all prior contracts and understandings
         between the parties and may not be changed or terminated orally, and no
         change, termination or attempted waiver of any of its provisions will
         be binding unless in writing and signed by the party against whom it is
         sought to be enforced.

Clause Headings

22       The clause headings are included for convenience only and have no legal
         effect.

Applicable Law and Jurisdiction;

23       This Agreement will be construed and the legal relations between the
         parties determined in accordance with the laws of the Cayman Islands
         and the parties agree to submit to the jurisdiction of the Cayman
         Islands Courts. Whenever possible, each provision of this Agreement
         will be interpreted in such a manner as to be effective and valid, but
         if any provision of this Agreement or the application of it is
         prohibited or held to be invalid, that prohibition or invalidity will
         not affect any other provision, or the application of any other
         provision which can be given effect without the invalid provision or
         application, and to this end the provisions of this Agreement are
         declared to be severable.
