Dear Ladies and Gentlemen:

This opinion is submitted pursuant to Item 601(b)(5) of Regulation S-K under the Securities Act of 1933 with respect to the registration of 10,500,000 shares of Class A common stock, par value $0.001, being offered by two (2) selling stockholders, and 51,700,000 shares of Class C common stock, par value $0.001 being offered by one hundred seventy-eight (178) selling securityholders (the “Shares”) on the terms and conditions set forth in the Registration Statement.

In that connection, I have examined original copies, certified or otherwise identified to my satisfaction, of such documents and corporate records, and have examined such laws or regulations, as have deemed necessary or appropriate for the purposes of the opinions hereinafter set forth.

In all such examinations, I have assumed the genuineness of all signatures on original documents, and the conformity to the originals of all copies submitted to me by the parties herein. 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 the Shares, when issued as contained in this registration statement, will be duly and validly issued, duly authorized, fully paid and non-assessable.

This opinion is limited to the laws of the State of Delaware and federal law as in effect on the date of the effectiveness of the registration statement, exclusive of state securities and blue-sky laws, rules and regulations, and to all facts as they presently exist.

I consent to the prospectus discussion of this opinion contained in the Registration Statement, the reproduction of this opinion as an exhibit to the Registration Statement, and to being named under the caption “Legal Matters” in the Registration Statement. In giving this consent, I do not hereby admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act.

Sincerely,
