of Control Payment Event, the Company will contribute an amount equal to three (3) times the Participant's Overall Contribution Percentage (determined on a Plan Year basis) multiplied by the Participant's Compensation (determined on a Plan Year basis) and, for the avoidance of doubt, this contribution amount shall not be offset by the Offset Amount or any other offset."

"(b)Final Contribution Amount.
