(1)	Based on the Company's EBT performance in 2012, 150% of the original award of 8,369 performance-based restricted stock units granted 2/21/12 were earned, resulting in an additional 4,185 units, for a total of 12,554 units. The restrictions will lapse with respect to 4,143 units on 2/21/14 and with respect to 4,269 units on 2/23/15, subject to continued employment by the Reporting Person on the remaining vesting dates.
(2)	Shares withheld by the Company to satisfy the Reporting Person's tax withholding obligation upon the vesting of restricted stock units.
(3)	The new grant is for 1,565 shares of common stock represented by time-based restricted stock units. The restrictions will lapse on 516 units on each of 2/21/14 and 2/23/15 and on 533 units on 2/21/16, subject to continued employment by the Reporting Person on the vesting dates.
(4)	The new grant is for 6,263 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.
