Explanation of Responses:

( 1 )On August 19, 2019, the reporting person filed a Form 4 reporting the vesting of restricted stock units ("RSUs") and performance stock units("PSUs"); however, the Form 4 failed to report in Table I (i) the acquisition of the RSUs that vested and (ii) the shares withheld for the payment of applicable income and payroll withholding taxes due on release. This acquisition and withholding is reported in this amended Form 4. ( 2 )On April 23, 2019, the reporting person mistakenly reported within Table I of a Form 4 an acquisition of 112,500 shares of common stock. This transaction, which represented the vesting of 112,500 restricted stock units, was not a reportable event, as the acquisition of those shares was reflected on a Form 4 previously filed by the reporting person on May 12, 2015.

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

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
