Explanation of Responses:

1. The acquired shares vested upon certification of a performance target on December 31, 2017 for a performance award previously granted to the executive officer.

2. Executive Officer elected to satisfy his tax withholding obligations upon vesting by having the issuer withhold a number of vested shares equal to that of the officer's tax liability.

3. On December 31, 2017, performance targets were achieved for an RSU grant that was previously made to the executive officer. 50% of these RSUs will vest on January 3, 2019 and the remaining RSUs will vest on January 3, 2020, subject to the executive officer's continued service to the Company.
