[1] The number of shares of time-based grants may, upon vesting, convert 50% into common stock and the remaining 50% into two incentive stock options for each RSU with an exercise price equal to the closing price of the Company's stock on that date for employees who have not met their stock ownership requirements. The number of shares of performance-based grants represents awards granted by the Company at the maximum achievement level of 130% of target payout. Actual shares that may be issued can range from 0% to 130% of target.
