Explanation of responses

F1Each restricted stock unit (RSU) represents a right to receive one share of the Issuer's common stock.
F2These shares were withheld in order to meet the tax withholding obligations of the award holder in connection with the vesting of the holder's restricted stock unit awards.
F3Award vests in annual installments over 4 years as long as the holder remains in service to the Company. Vested shares will be delivered to the holder shortly after the vesting date.
F4These units do not expire.

Remarks

This amended Form 4 corrects an error in Table I (Non-Derivative Securities Acquired, Disposed of, or Beneficially Owned) reflected on the original Form 4 filed on March 14, 2018. The Issuer inadvertently triggered a sale in the open market of 4,502 shares at a price of $5.95 in order to meet the tax withholding obligations of the award holder in connection with the vesting of the holder's restricted stock unit award. Prior to settlement of the sale, the Issuer reacquired the shares in the open market at the request of and on behalf of the holder based on the holder electing to withhold shares in order to meet the tax withholding obligations in connection with the vesting of the holder's restricted stock unit award without a sale of Issuer shares.
