     Based upon the foregoing, we are of the opinion that to the extent that the Shares of Common Stock are issuable upon conversion of the series A preferred stock, when issued in accordance with the conversion in accordance with the conversion provisions of the Certificate of Designation filed with the Nevada Secretary of State on May 27, 2010, they will be legally and validly issued, fully paid and nonassessable, and to the extent the Shares are issuable upon exercise of the Warrants, when issued in accordance with the exercise provisions of such Warrants, will be duly authorized and legally issued by the Company and fully paid and nonassessable. This opinion is limited to matters governed by the laws of the State of Nevada.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the use of our name under the caption “Legal Matters” in the Registration Statement and in the Prospectus included therein. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Securities and Exchange Commission promulgated thereunder.
