This opinion is based exclusively on the Maryland General Corporation Law and the federal law of the United States of America.

Based upon and subject to the foregoing, it is our opinion that the Shares, when issued for payment as described in the Company’s Prospectuses offering the Shares and in accordance with the Company’s Articles of Incorporation for not less than $ 0.001 per share, will be legally issued, fully paid and non-assessable by the Company.

We consent to the filing of this opinion as an exhibit to the Amendment to the Company’s Registration Statement.

	Very truly yours,
