*	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 represents the number of Common Shares beneficially owned less the shares sold on November 17, 2009 in the amount of 114,129 shares. The Common Shares beneficially owned represent the underlying to the Senior Redeemable Convertible Preferred Stock (the "Preferred Stock") which converts to 123,628,032 Common Shares plus an additional 9,767,640 Common Shares received as a result of converting a portion of the Preferred Stock.
(2)	As of November 17, 2009 each share of Preferred Stock converts into 571.43 Common Shares plus a make-whole premium which amounted to approximately 912 additional common shares for 1 share of Preferred Stock.
(3)	The make whole premium is equal to the discounted net present value of future dividends (until June 2010) divided by the Volume Weighted Average Price of the common stock for the last 10 trading days prior to the conversion date discounted 10%. Therefore, the make whole premium fluctuates with the changes in the price of the Common Shares and the amount of future dividends.
