WHEREAS, Director has advised the Board that the shares of Deferred Stock credited to his Deferred Stock Account are subject to taxation under the laws of Australia and has requested that the Board authorize the acceleration of a portion of such shares so that he may pay applicable taxes resulting from his participation in the directors compensation program;
