(“Eastern”), a New Jersey corporation, Hamburg Quarry Limited Liability Company (“Hamburg”), a New Jersey limited liability company, and Master Mix Concrete, LLC (“Master Mix Concrete”), a New Jersey limited liability company, 160 East 22nd Terminal LLC, a New Jersey limited liability company (“160 East”); Ferrara West LLC, a New Jersey limited liability company (“Ferrara West”); Colonial Concrete Co., a New Jersey corporation (“Colonial”); and Premco Organization, Inc., a New Jersey corporation (“Premco”) (collectively referred to as the “New Jersey Guarantors”), which are subsidiaries of U.S. Concrete, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission of a Registration Statement on Form S-4 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”).

Guarantees of the New Jersey Guarantors are referred to herein collectively as the “New Jersey Guarantees”. We refer to the Indenture and the New Jersey Guarantees collectively as the “Opinion Documents.” This opinion is being furnished at the Company’s request in connection with the opinion of Akin Gump Strauss Hauer & Feld LLP, counsel to the Company, whose opinion is being furnished to the Company in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act. We have not acted as general counsel of the New Jersey Guarantors; accordingly, you understand that, as more particularly hereinafter described, no inference as to our knowledge of any fact relevant to the opinions set forth herein should be drawn from our representation of the New Jersey Guarantors in this particular matter.

You are aware, and we hereby confirm, that we have not been involved in the negotiation or preparation of the Opinion Documents, or any of the related agreements executed or delivered in connection with the Exchange Notes. We have been retained solely for the purpose of rendering certain opinions pursuant to New Jersey law.

We have examined originals or certified copies of such corporate records of the Company and the New Jersey Guarantors and other certificates and documents of officials of the Company and the New Jersey Guarantors, public officials and others as we have deemed appropriate for purposes of this letter. We have assumed 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 authentic original documents of all copies submitted to us as conformed, certified or reproduced copies, and that the Exchange Notes have been or will be duly authenticated in accordance with the terms of the Indenture.

We have also assumed the due authorization of the Opinion Documents by the parties thereto other than the New Jersey Guarantors, and that each Opinion Document will constitute a valid and binding obligation of the Trustee, enforceable against the Trustee in accordance with its terms. As to various questions of fact relevant to this letter, we have relied, without independent investigation, upon certificates of public officials and certificates of officers of the Company and the New Jersey Guarantors, all of which we assume to be true, correct and complete. We express no opinion on whether the Guarantees will be valid and binding obligations of the New Jersey Guarantors.

In rendering our opinion, with your consent, we have assumed, without any independent investigation, that:

(i) Where we opine as to a future event, the facts and the laws in effect at such time are identical to the laws currently in effect;

(ii) The New Jersey Guarantors have received, or will receive, consideration provided for in, or contemplated by, the Opinion Documents; and

(iii) There are and will be no other understandings, agreements or documents between and among the parties to the Opinion Documents that would expand or otherwise modify the obligations of the respective parties with respect to the transaction or the Opinion Documents or that would otherwise have an effect on our opinion rendered herein.

We hereby consent to the filing of this letter with the Securities and Exchange Commission as an exhibit to the Registration Statement and to the use of our name in the Prospectus forming a part of the Registration Statement under the caption “Legal Matters”. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act and the rules and regulations thereunder. This letter is given as of the date hereof, in connection with the transactions referred to in the Opinion Documents, and except as otherwise provided herein, may not be circulated to, or by, any other person or entity.
