                Computation Period for purposes of applying the vesting rules
                under this Plan so long as that Participant continues to be
                employed with the Employer as of December 31, 2003. For all

                percentage may vary (i) among Participants employed by different
                Employers; or (ii) with the Participant's rate of deferral, but
                must be uniform for Participants with equal rates of Elective
