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)	The reporting persons are: (i) RBF Capital, LLC ("RBF"); and (ii) Richard B. Fullerton, RBF's managing member.
(2)	The securities reported on this Form 4 are beneficially held by Fullerton Capital Partners, L.P. ("FCP") and other investment limited partnerships for which RBF serves as the general partner and/or investment manager (the "Funds"). Other than FCP, none of the Funds is itself the beneficial owner of more than 10% of the issuer's common stock. As a greater than 10% beneficial owner, FCP is separately reporting its holdings on a Form 4.
(3)	RBF and Mr. Fullerton may be deemed to beneficially own the securities owned by FCP and the Funds insofar as they may be deemed to have the power to direct the voting or disposition of such securities. Each of RBF, Mr. Fullerton, FCP and the Funds disclaims beneficial ownership in these securities, however, except to the extent of their respective pecuniary interests therein.

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

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
