Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	This Form 4 is filed jointly by Raging Capital Management, LLC ("Raging Capital") and William C. Martin (collectively, the "Reporting Persons"). The Reporting Persons previously collectively beneficially owned more than 10% of the Issuer's outstanding shares of Common Stock. Each of the Reporting Persons disclaims beneficial ownership of the securities of the Issuer previously reported by them except to the extent of his or its pecuniary interest therein.
(2)	This Form 4 relates to securities of the Issuer previously 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 securities held by Raging Master pursuant to an Investment Management Agreement, dated November 9, 2012 (the "IMA"). 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 securities held by Raging Master. Raging Master specifically disclaims beneficial ownership of securities held by it by virtue of its inability to vote or dispose of such securities as a result of the IMA.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
