NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties agree as follows: 1. EXECUTIVE INCENTIVE COMPENSATION PLAN.

AMI shall be obligated to pay and hereby agrees to pay Executive any and all amounts due him pursuant hereto within 7 calendar days after the occurrence of any Change of Control. 2. SEVERANCE.
