Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 5(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 securities to which this filing relates are held directly by PFS Trust ("PFS Trust") and Glenbrook Capital Management Inc. Employee Profit-Sharing Plan ("GCM EPSP"). Glenbrook Capital Management (the "Reporting Person") serves as the investment manager to each of PFS Trust and GCM EPSP. The Reporting Person disclaims beneficial ownership of the securities to which this filing relates for purposes of Section 16 of the Securities and Exchange Act of 1934, as amended, except to the extent of his or its pecuniary interest therein, if any.
(2)	Pursuant to the terms of the Series I Common Stock Warrants (the "Warrants"), the Reporting Person cannot exercise any of the Warrants to the extent the Reporting Person would beneficially own, after any such exercise, more than 4.99% of the outstanding Common Stock (the "4.99% Blocker") for the Warrants held by GCM EPSP, or 9.99% of the outstanding Common Stock (the "9.99% Blocker") for the Warrants held by PFS Trust. Consequently, at this time, the Reporting Person is not able to exercise the Warrants reported herein due to the 4.99% Blocker and the 9.99% Blocker.

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.
