Unless otherwise defined herein, capitalised terms have the meanings assigned to them in the Registration Statement.

LIMITATIONS

Our opinion is limited to, and should be construed in accordance with, the laws of Bermuda at the date of this opinion. We express no opinion on the laws of any other jurisdiction.
