Explanatory Paragraph:

The Company is de-registering 285,080 shares from 601,005 shares of common stock
underlying certain warrants previously issued to its placement agent, C.P. Baker
Securities, Inc., which shares are registered on the current effective Form S-1
registration statement. After the de-registration of such shares, 315,925
shares of common stock underlying C.P. Baker Securities, Inc.'s warrants will
remain registered under the registration statement.

In connection with the Series A Preferred Stock transactions and the bridge loan
with Sotomar - Empreendimentos Industriais e Imobiliarios (occurring between
February, 2006 and April, 2006, and unrelated to the Company's public offering
of securities), described in the Form S-1 registration statement, the Company
issued to its placement agent, C.P. Baker Securities, Inc., warrants (i) to
purchase up to an aggregate 150,335 shares of the Company's common stock at an
exercise price of $2.125 per share; (ii) to purchase up to an aggregate 30,067
shares of the Company's Series A Preferred Stock at an exercise price of $17.00
per share; and (iii) to purchase up to 150,000 shares of the Company's common
stock at an exercise price of $1.27. All 601,005 shares of common stock
underlying the above warrants are registered on the current effective Form S-1
registration statement.

As part of its NASD approval process, the placement agent specifically requested
that the Company de-register 285,080 shares of common stock underlying its
warrant to purchase 33,085 shares of the Company's common stock, its warrant to
purchase 48,675 shares of the Company's common stock, its warrant to purchase up
to 6,617 shares of the Company's preferred stock and its warrant to purchase up
to 13,715 shares of the Company's preferred stock.

In addition, as part of the NASD approval, the Company confirms that the maximum
commission or discount to be received by any NASD member or independent
broker/dealer will not be greater than eight (8) percent for the sale of any
securities registered under the Form S-1 registration statement pursuant to SEC
Rule 415.
