(1)	Based on the Company's EBT performance in 2012, 150% of the original award of 8,406 performance-based restricted stock units granted 2/21/12 were earned, resulting in an additional 4,204 units, for a total of 12,610 units. The restrictions will lapse with respect to 4,161 units on 2/21/14 and with respect to 4,289 units on 2/23/15, subject to continued employment by the Reporting Person on the remaining vesting dates.

(4)	The new grant is for 7,232 shares of common stock represented by performance-based restricted stock units, which may be adjusted up or down at the time the performance restriction lapses.
