                  death, you (or your estate) will have five years from your
                  termination date to exercise your option, unless the option

                  permanently terminating your employment, with no intention of
                  engaging in a full-time job, after reaching age 65, or after
                  reaching age 55 if your age plus your years of service equals
                  65 or more. This definition of retirement is used only for
                  purposes of this agreement.

                  All other cases. If your employment terminates because you
                  quit, or for any other reason other than retirement, permanent
                  disability or death, you (or your estate, if you die within
                  the period) will have 90 days from your termination date to
                  exercise your option, unless the option term ends earlier, in
                  which case you (or your estate) will have until the end of the
                  term to exercise.

                  Regardless of the cause of your termination, you (or your
                  estate) can exercise your option only to the extent it is
                  vested on your termination date.

TRANSFERABILITY   Your option is not transferable except by will or the laws of
                  descent and distribution. During your lifetime only you can
                  exercise your option. This option shall not be subject to
                  attachment or similar process. Any attempted sale, pledge,
                  assignment, transfer or other disposition of your option
                  contrary to the provisions of this agreement, or the levy of
                  any attachment or similar process upon your option, shall be
                  null and void without effect.
