(the "Company") believes that the threat or occurrence of a Change in Control (as defined in the Appendix) of the Company may cause you undue concern for your financial security and distract your attention from the operations of our businesses, which would be detrimental to the Company and its shareholders.

For any fiscal year during which you are in the employ of the Company on the date of occurrence of a Change in Control, you shall be guaranteed an annual bonus for that fiscal year (the "Change in Control Year") in an amount no less than the annual bonus that was paid or payable to you for the most recently ended fiscal year prior to a Change in Control (the "Bonus") provided that you are in the employ of Company (or its successor) on the last day of the Change in Control Year.
