your individual objectives. I will meet with you during the first few weeks of your employment to
agree on your individual objectives for FY 2005. The performance-based bonus plan will be
structured in such a way that should you, your team and the Company exceed certain objectives

any management performance-based bonus determined to be payable to you for the full FY 2005. If
your FY05 bonus is calculated to be less than $150,000, you will not be required to repay the
difference. Mr. Warren Kocmond
