In consideration for Employee entering into this Agreement, Company shall pay Employee the amounts indicated in Section 7(a) in that certain Executive Employment Agreement dated and effective as of April 2, 2004 made by and between Company and Employee (the “Employment Agreement”).

Such Claims include, but are not limited to, claims based upon any violation of Company’s policies and regulations or any written or oral
