| F1 | Includes dividend equivalents earned with respect to the vested restricted stock units. |
| F2 | This amount reflects a reduction of 20 shares that were over-reported on the Reporting Person's last Form 4 (as determined by a reconciliation to the Reporting Person's records). |
| F3 | SARs become exercisable and vest only upon the achievement of both price and time requirements. To vest, each one-third of the grant must attain 10%, 15% and 20% stock appreciation, respectively (which must be maintained for a minimum of thirty consecutive trading days) from the grant date closing price of $24.98 per share and no more than one-third of the grant can vest per year during the first three years. |
