Mr. Andrews will not receive any shares of Common Stock if total shareholder return has decreased by more than 50% since the grant date. The number of shares of Common Stock that Mr. Andrews may receive is interpolated for total shareholder return falling between Threshold, Target, and Maximum levels.
