Re: Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as special counsel to United Business Holdings, Inc., a Nevada corporation (the “Company”), in connection with the Company’s registration statement on Form S-1 filed with the Securities and Exchange Commission on October 9, 2008 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Act”).

The Registration Statement covers the registration of (i) 2,970,000 shares of common stock, $0.01 par value per share (the “Common Stock”) of the Company (the “Shares”), (ii) warrants to purchase up to 246,194 shares of Common Stock (“Organizer Warrants”), (iii) the shares of Common Stock issuable upon the exercise of the Organizer Warrants, (iv) warrants to purchase up to 594,000 shares of Common Stock (“Shareholder Warrants”), and (v) the shares of Common Stock issuable upon the exercise of the Shareholder Warrants.

In this capacity, we have examined originals or copies of the following documents:

(1) the Registration Statement;

(2) the form of Organizer Warrant Agreement filed as an exhibit to the Registration Statement;

(3) the form of Shareholder Warrant Agreement filed as an exhibit to the Registration Statement (the documents identified in (2) and (3) are referred to, collectively, as the “Warrant Agreements”); and

(4) a certificate from an officer of the Company dated as of the date hereof, certifying: (a) the articles of incorporation of the Company, as amended; (b) the bylaws of the Company, as amended; (c) resolutions of the board of directors of the Company dated as of , 2008, authorizing the Registration Statement and other matters.

This opinion is based entirely on our review of the documents listed in the preceding paragraph, and we have made no other documentary review or investigation of any kind whatsoever for purposes of this opinion.

In conducting our examination, we have assumed: (i) the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies or forms and the authenticity of the originals of such documents; and (ii) that the Warrant Agreements will be executed and delivered by the Company and the warrantholders as in the forms filed as exhibits to the Registration Statement and, when so executed and delivered, will be the valid and binding obligations of the Company and the respective warrantholders.

Based upon the foregoing, and in reliance thereon, and subject to the limitations and qualifications set forth herein, we are of the opinion that (A) the Shares, Shareholder Warrants and Organizer Warrants are duly authorized; (B) when the Shares and Shareholder Warrants are issued and delivered to investors, and the Organizer Warrants are issued and delivered to the organizers, all as described and in exchange for the consideration described in the Registration Statement, the Shares, Shareholder Warrants and Organizer Warrants will be legally and validly issued; and (C) assuming that: (i) the shares of Common Stock to be issued pursuant to the Shareholder Warrants and the Organizer Warrants are issued pursuant to the terms thereof, (ii) the Company maintains an adequate number of authorized but unissued shares and/or treasury shares of Common Stock available for issuance to those persons who purchase shares through the exercise of Shareholder Warrants and/or Organizer Warrants, and (iii) the consideration for the shares of Common Stock issued pursuant to the Shareholder Warrants and Organizer Warrants is actually received by the Company as provided in the Shareholder Warrants and Organizer Warrants and exceeds the par value of such shares, then the shares of Common Stock issued upon the due and valid exercise of the Shareholder Warrants and Organizer Warrants will be duly and validly issued, fully paid and nonassessable.

We are attorneys admitted to practice in the State of Texas. We express no opinion concerning the laws of any jurisdiction other than the laws of the United States of America and the State of Texas.

This firm hereby consents to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and to references to our firm included in or made a part of the Registration Statement. In giving this consent, this firm does not admit that it comes within the
