                         treasury shares which have not been transferred or
                         cancelled shall be deducted.)

    The exercise price will not be adjusted in case of issuance of new common
    shares in connection with mergers.

8.  Issuance of Additional Options

    Upon the occurrence of the Company's capitalization of retained earnings or
    capital reserves, in addition to adjusting the exercise price in accordance
    with provisions set forth in Paragraph 7(1) above, the Company will issue
    additional options in proportion to the increase of paid-in capital (only
    integral options will be issued and any fractional options resulting
    therefrom will be disregarded) at the adjusted price to holders of existing
    unvested or unexercised options, provided that there are sufficient common
    shares reserved for granting the options as specified in the Articles of
    Incorporation of the Company.

9.  Procedures for Exercising Options

    (1) Except during a period in which the shareholders' book is closed in
        accordance with relevant laws; or, the period from three (3) business
        days prior to the date of public announcement to close shareholders'

        relevant authority within fifteen (15) days from each quarter end.
