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)	Each share of the Senior Redeemable Convertible Preferred Stock ("SRCPS") was convertible into approximately 333.33 shares of common stock, subject to adjustment, at any time after May 15, 2007 and has no expiration date. Specifically, the SRCPS converts into a number of Common Shares equal to the number of shares of SRCPS multiplied by the quotient of the Liquidation Preference of $1,000 divided by the Conversion Price. On May 1, 2008, the Conversion Price was adjusted to $1.75, which means each SRCPS now converts into approximately 571.43 shares of common stock. This does not include shares which would be deliverable as a make-whole premium for conversions prior to June 1, 2010 to make whole for dividends that would have been payable absent the conversion. As of May 9, 2008, the make-whole premium amounted to 221 common shares for each share of SRCPS.
(2)	As set forth in Footnotes (1) and (2), on May 1, 2008, the Conversion Price was adjusted to $1.75.
(3)	As set forth in Footnotes (1) and (2), based on the revised adjusted conversion ratio, the number of shares underlying the SRCPS changed as of May 1, 2008.
(4)	There is no expiration date.
