Explanation of Responses:
(1)	Each share is represented by a Restricted Stock Unit ("RSU"). 100% of the RSUs will vest upon the earlier of the one (1) year anniversary of the grant date or the day prior to the Issuer's 2020 Annual Meeting occurring after the grant date, in each case, subject to the Reporting Person's continued service as of the applicable vesting date and acceleration of vesting upon a change of control.
(2)	Each outstanding share of the Common Stock of the Issuer was converted into the right to receive $24.50 per share in cash, as described in the Merger Agreement.
(3)	Certain of these securities were RSUs that represented the Reporting Person's right to receive Common Stock shares of the Issuer. The RSUs were subject to acceleration of vesting, cancelled and converted automatically into the right to receive $24.50 per share in cash, as described in the Merger Agreement.
(4)	Shares held by Third Millennium Trust ("Millennium"). The Reporting Person is the trustee of Millennium, and has voting and investment power with respect to the shares held by Millennium.
