This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related Prospectus, other than as expressly stated herein with respect to the issuance of the shares of Common Stock offered for sale by the Prospectus.

As such counsel, we have examined the Registration Statement and copies certified or otherwise, identified to our satisfaction of the Company’s Articles of Incorporation, as amended, and Amended and Restated Bylaws and such other documents, records, and instruments as we have deemed appropriate for purposes of the opinion set forth herein. We have relied upon certificates and other assurances of officers of the Company and others as to factual matters material to this opinion without having independently verified such factual matters.

We have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of the documents submitted to us as originals, the conformity with the originals of all documents submitted to us as certified or copies, and the authenticity of the originals of all documents submitted to us as copies.

The opinions expressed herein are limited to the corporate laws of the State of Nevada, as currently in effect, and we express no opinion as to the effect of any other law of the State of Nevada or the laws of any other jurisdiction.
