In addition, to the exchange described in Paragraph B below, the Company has also offered to issue until January 31, 2015 (i) to the Series B Preferred shareholders in exchange for the Series B Preferred shares together with all accrued and unpaid dividends thereon through the date of the exchange shares of Common Stock of the Company (the number of shares of Common Stock to be issued is derived by dividing (x) the sum of the total cash paid by the Series B Preferred holder to the Company for its initial investment in the Series B Units (comprised of Series B Preferred shares and a warrant) plus the accrued and unpaid dividends on the Series B Preferred shares by (y) $1.75 and (ii) to the Series B Preferred shareholders as well as the bridge warrant holders that invested in the Company a warrant in exchange for their existing warrant with terms substantially similar to their existing warrants; however, the new warrant terms will provide for a reduction in exercise price, the elimination of the anti-dilution rights for new stock issuances at per share prices lower than the exercise price, the addition of assignment rights for the warrant holders and the addition of certain buy-in–rights for the warrants that previously did not have buy-in rights in the event of the Company’s failure to timely deliver the shares of Common Stock underlying the warrant but in no event later than January 31, 2015.

B. The Securityholder owns a warrant exercisable for ________ shares of Common Stock of the Company (the “Existing Warrant”) that was issued as partial consideration for the services provided to the Company by the Placement Agent in its offering that was consummated in 2013 and desires to exchange the Existing Warrant for a warrant in the form attached hereto as Exhibit A (the “New Warrant”) initially exercisable for ________ shares of Common Stock (the “Underlying Shares”), which warrant substantially similar to the Existing Warrant; however, the new warrant terms will provide for a reduction in exercise price to $1.925 per share, the elimination of the anti-dilution rights for new stock issuances at per share prices lower than the exercise price, the addition of assignment rights for the warrant holders and the addition of certain buy-in–rights for the warrants that previously did not have buy-in rights in the event of our failure to timely deliver the shares of Common Stock underlying the warrant.

C. The exchange of the Existing Warrant for the New Warrant (the “Exchange”) will be made in reliance upon the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”).
