In accordance with the Employee Share Incentive Plan (“the Preference Share Plan”), you are hereby advised that the Grant Date is July 14, 2005 for benefits you have accrued during the year ended 31 December 2004.

Accordingly you are granted 48 Preference Shares in the Company. You have the option to purchase an equal number of Preference Shares at a price of US$18.31 or CI$15.26 each, which has been calculated in accordance to the terms of the Preference Share Plan.

These options are exercisable in accordance to the terms of the Option Plan. You furthermore have the opportunity to obtain an equal amount of options to purchase Ordinary Shares of the Company, in accordance to the terms of the Option Plan, if you exercise your right to purchase the above additional Preference Shares before August 15, 2005.
