by a combination of such methods of payment. Payment instructions will be
received subject to collection.

      Option shall be exercisable by the Optionee, subject to paragraph 3(d)
      above, only within one year after such termination and only to the extent
      the Option was exercisable on the date of termination of director status.

            (b) If, however, any termination of director status is due to
      retirement or permanent disability, the Option shall be fully exercisable
      by the Optionee within three (3) years, subject to paragraph 3(d) above,
      after such termination of director status.

            (c) If the Optionee shall die while entitled to exercise the Option,
      the Optionee's estate, personal representative or beneficiary, as the case
      may be, shall have the right to fully exercise the Option within three (3)
      years, subject to the provisions of paragraph 3(d) above, after the
      Optionee's death.
