is negative, such negative amount will adjust the EBITDA targets for the
following fiscal year(s), The Incentive Bonus shall be payable annually and as
soon as practicable following the Employer’s completion of its audited
financials for the fiscal year to which the Incentive Bonus applies. An
additional 7.5% of EBITDA generated by the International Nuclear Operations, as

of the Employer at the discretion of the Executive in consultation with the
Employer. Notwithstanding anything to the contrary in this Agreement, upon
Executive’s termination by the Employer without Cause (as defined below) or due

days between the beginning of the fiscal year in which such termination occurs
and the date of Employee’s termination of employment, divided by 365, which
