                                         of the Company;

                                         policy and in consultation with the chairman and/or chief executive, as appropriate,
                                         determine the total individual remuneration package of the chairman of the Board, each
                                         executive director, Company secretary and other designated senior executives including
                                         bonuses, incentive payments and restricted share awards or other share awards; and

                                         chief executive’s compensation, the Committee shall consider the Company’s
                                         performance and relative shareholder return, the value of similar incentive awards to
                                         chief executive officers at comparable companies, and the awards given to the Company’s
                                         chief executive in past years.
