Explanation of Responses:

Id Content
F1 The sale reported on this Form 4 represents shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. The sale occurred automatically to satisfy the tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the Reporting Person.
F2 The amount of securities beneficially owned by the Reporting Person, as reported in Forms 4 filed by the Reporting Person subsequent to the Transaction Date but prior to the date of this Form 4, did not reflect this sell to cover transaction.
