The sale of up to 500,000 Units is being made pursuant to an underwriting agreement, dated as of July 23, 2013 (the “Underwriting Agreement”), by and between the Company and Global Hunter Securities, LLC, as representative of the several underwriters identified therein (the “Underwriters”), including up to 188,893 Units being offered in cancellation of up to $4.3 million of the Company’s outstanding indebtedness. For purposes of this opinion, shares of Common Stock issuable upon exercise of the Warrants are referred to as “Warrant Shares.”

This opinion is being furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), promulgated under the Securities Act, in connection with the Registration Statement.
