                           Account;

                  (iv)     in a joint and survivor life annuity with monthly

                           life of the Participant's survivor; and, if both the
                           Participant and the Participant's survivor die before
                           the total amount paid equals the Participant's Prior
                           Employer Account, payments continue to the
                           Participant's beneficiary until the total amount paid
                           equals the Participant's Prior Employer Account;

                  (v)      in installment payments made monthly for a fixed
                           period of time equal to or greater than 60 months; or

                  (vi)     in a series of flexible income payments for an amount
                           each year equal to that elected by the Participant
                           which, in the year the Participant attains age 70
                           1/2, must be equal to or greater than a minimum
                           amount."

                                       3.
