Company's 2006 Long-
Term Incentive Plan.

Under the terms of the Plan, the Management Development and Compensation
Committee of the Board
of Directors is required to make equitable adjustments to Stock Option grants if
there is a change in the
capital structure of the Company. As a result of the $4.50 special cash dividend
declared by the Board of
Directors on February 25, 2008, your Stock Option grant has been adjusted. The
exercise price has been
reduced by $12.50 per share. Your grant is now as follows:

All other terms and conditions of your Stock Option grant are unchanged. You
should file this Notice of
Stock Option Adjustments with your original grant documents.

Please call Scott Webster if you have questions.
