Explanation of Responses:

( 1 )This acquisition represents shares received under the Company's short-term incentive bonus plan. ( 2 )Each market stock unit represents a right to receive one share of the Issuer's common stock. ( 3 )This award represents market stock units with vesting based on performance of the Company's common stock compared to the Nasdaq Composite Index over a period of three years. Depending on the level of performance actually achieved, the number of shares that may vest under this award will vary. The amount included in the table above represents a portion of the grant originally made to the Reporting Person on March 2, 2017, but was contingent upon the approval of an amendment to the Company's equity incentive plan at our 2017 annual meeting of stockholders. The market stock units included in the table above will only be eligible to vest if performance is above-target. ( 4 )These units were received as a grant or award for no consideration.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
