| | (1) | Represents the weighted average contractual life remaining in years. |
| | (2) | Aggregate intrinsic value represents the total pre-tax intrinsic value (i.e., the difference between the Company’s average of the high and low stock price on the last trading day of the quarter and the option exercise price, multiplied by the number of shares) that would have been received by the option holders if they had exercised their options on the last day of the quarter. This amount will change based on the fair market value of the Company’s stock. |
