Further information regarding the identity and background of certain of the Reporting Persons is set forth in Exhibit B which is attached hereto.
	During the last five years, none of the Reporting Persons, nor, to the best knowledge of the Reporting Persons, any of their respective executive officers, their respective managing members or any persons controlling their respective managing members has: (1) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (2) been party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4.	Purpose of Transaction.
	The Reporting Persons have acquired the Shares for investment purposes and will continue to analyze their investment in the Issuer on an ongoing basis. As part of this investment analysis process, the Reporting Persons reserve the right to engage in discussions with management of the Issuer and with third parties that may have an interest in the business affairs of the Issuer in order to monitor their investment and consider possible strategic alternatives. In addition, the Reporting Persons may suggest changes to the composition of the Issuer’s Board of Directors as circumstances warrant.
	Depending upon such discussions and consideration of strategic alternatives, the Reporting Persons could support one or more of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
