                                    retirement pension and the Disability
                                    Pension of a Member who has retired,
                                    terminated his employment or became disabled
                                    as the case may be, before 2 September 2000,
                                    including the pension payable under any
                                    attached elected pension payment guarantee,
                                    either contingent or in payment, and the
                                    pension, either deferred or in payment, to a
                                    surviving spouse, shall be augmented on 1

                                    Notwithstanding the preceding, this pension
                                    augmentation is not applicable if a Member
                                    at his Commencement Date has less than 100%
                                    of the Company's contributions to his
                                    retirement income vested and has less than
                                    10 years of Credited Service.

                                   determined under subparagraph 19.06.2.3) x
                                   (1 + the augmentation factor determined under
