Explanation of Responses:
( 1)	This Form 3 is filed jointly by Raging Capital Management, LLC ("Raging Capital") and William C. Martin (collectively, the "Reporting Persons"). Each of the Reporting Persons may be deemed to be a member of a Section 13(d) group that collectively owns more than 10% of the Issuer's outstanding shares of Common Stock. Each of the Reporting Persons disclaims beneficial ownership of the securities reported herein except to the extent of his or its pecuniaryinterest therein.
( 2)	Represents securities held directly by Raging Capital Master Fund, Ltd. ("Raging Master"). Raging Capital is the Investment Manager of Raging Master. William C. Martin is the Chairman, Chief Investment Officer and Managing Member of Raging Capital. Raging Master has delegated to Raging Capital the sole authority to vote and dispose of the securities held by Raging Master pursuant to an Investment Management Agreement, dated November 9, 2012, as amended and restated on December 21, 2016 (the "IMA").
( 3)	The IMA may be terminated by any party thereto effective at the close of business on the last day of any fiscal quarter by giving the other party not less than sixty-one days' written notice. As a result, each of Raging Capital and William C. Martin may be deemed to beneficially own the securities held by Raging Master. Raging Master specifically disclaims beneficial ownership of the securities held by it by virtue of its inability to vote or dispose of such securities as a result of the IMA.
