In all such examinations, I have assumed the genuineness of all signatures on original documents, and the conformity to the originals or certified documents of all copies submitted to me as conformed, Photostat or other copies. In passing upon certain corporate records and documents of the Company, I have necessarily assumed the correctness and completeness of the statements made or included therein by the Company, and I express no opinion thereon. As to the various questions of fact material to this opinion, I have relied, to the extent I deemed reasonably appropriate, upon representations or certificates of officers or directors of the Company and upon documents, records and instruments furnished to me by the Company, without verification except where such verification was readily ascertainable.

Based on the foregoing, I am of the opinion that (i) the 1,500,000 shares to be offered by the company will when sold be legally issued, fully paid and non-assessable, are and will be when sold in this offering be legally issued, fully paid and non-assessable.

This opinion is limited to the laws of the State of Nevada and federal law as in effect on the date of the effectiveness of this registration statement.

I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of my name under the caption "Interests of Named Experts and Counsel" in the prospectus comprising part of the Registration Statement.
