Explanation of Responses:
(1)  Represents withholding of shares to satisfy tax obligations upon the vesting of restricted stock
(2)  Each Restricted Stock Unit ("RSU") represents the right to receive one share of the common stock of the Issuer.
(3)  On February 26, 2019, 4,576 RSUs were granted to the reporting person. 1,526 of these RSUs vested on February 26, 2020, another 1,525 RSUs vested on February 26, 2021, and the remaining 1,525 RSUs will vest on February 26, 2022.
(4)  On February 26, 2020, 4,635 RSUs were granted to the reporting person. One-third of these RSUs will vest on each of the first, second and third anniversaries of the grant date.
(5)  On February 27, 2018, 6,000 Restricted Stock Units ("RSUs") were granted to the reporting person. One-third of these RSUs vested on each of the first, second, and third anniversaries of the grant date.
(6)  Each Performance Share Unit ("PSU") represents the contingent right to receive one share of the Issuer's common stock based on certain vesting conditions.
(7)  On February 27, 2018, 3,000 PSUs were granted and the vesting and award of Issuer's common stock was contingent upon achievement of specified performance targets over the three year period from 2018 through 2020, with potential to earn a number of shares of common stock between 0% and 200% of the number of target PSUs awarded. The Issuer determined that the maximum performance conditions were fully satisfied, and as a result, 6,000 PSUs vested.
