Explanation of Responses:

1. Each restricted stock or performance unit represents a contingent right to receive one share of Issuer's common stock. The units were awarded at no cost to Reporting Person.

2. 6.25% of the stock units subject to the award will vest on May 20, 2016 and 6.25% of the shares subject to the award will vest in equal quarterly installments thereafter, provided that Reporting Person remains in continuous service through each vest date. The quarterly vest dates are February 20, May 20, August 20 and November 20.

3. 1/3 of the units will vest quarterly over approximately 4 years from the date on which the average closing price per share of the Company's common stock ("ACP") has been at or above $11.91 for any period of 90 consecutive calendar days ("90-day Period"); 1/3 of the units will vest quarterly over approximately 4 years from the date on which the ACP has been at or above $12.82 for any 90-day Period; 1/3 of the units will vest quarterly over approximately 4 years from the date on which the ACP has been at or above $13.74 for any 90-day Period. The vesting conditions will not be deemed to be satisfied until and unless the Company's Compensation Committee certifies they are satisfied, at which time the units will vest on the next established quarterly vest date following such certification. Reporting Person must remain in continuous service through each vest date.
