reduce the Participants Compensation by any percentage up to 15 percent,
in increments of one half percent, and to have the amount by which the
Participants Compensation is reduced contributed on the Participants

the Employee becomes eligible to participate and notifies the Plan Administrator

earned as of the effective date of the election.
