The following constitutes Amendment No. 3 to the statement on Schedule 13D previously filed by the undersigned on January 3, 2012, as amended by Amendment No. 1 thereto filed on February 27, 2012 and by Amendment No. 2 thereto filed on February 28, 2012 (the “Schedule 13D”). Information reported in the Schedule 13D remains in effect except to the extent that it is amended, restated, or supplemented by information contained in this Amendment No. 3. Capitalized terms used but not defined in this Amendment have the respective meanings set forth in the Schedule 13D.

Item 4 of the Schedule 13D is hereby amended and restated as follows:

The Common Shares and Convertible Notes covered by this statement were purchased for investment by the Accounts (as defined below).

(a) On December 20, 2012, Whippoorwill entered into an Exchange and Consent Agreement with the Issuer (“Exchange Agreement”) pursuant to which Whippoorwill has agreed, subject to the terms of the Exchange Agreement, to tender all its Convertible Notes in an exchange offer (the “Exchange Offer”) proposed to be made by the Issuer as contemplated in the Term Sheet attached as Exhibit A to the Exchange Agreement (the “Term Sheet”). Pursuant to the Exchange Agreement, Whippoorwill has also agreed to consent to certain amendments to the Indenture relating to the Convertible Notes that are expected to be proposed by the Issuer in connection with the Exchange Offer as described in the Term Sheet. If the Exchange Offer is successfully consummated, Whippoorwill expects to receive new non-convertible debt securities of the Issuer (the “9.5% Senior Secured Notes”) as described in the Term Sheet in exchange for its Convertible Notes in the Exchange Offer. The information provided and incorporated by reference in Item 6 is hereby incorporated by reference in this Item 4.

Except as described herein, none of the Reporting Persons or, to the best of their knowledge, any of the Whippoorwill Covered Persons, have a present plan or proposal that relates to or would result in any of the actions specified in clauses (b) through (j) of Item 4 of Schedule 13D.

The Reporting Persons may from time to time acquire beneficial ownership of additional equity or non-equity securities of the Issuer and may from time to time cease to have beneficial ownership of Common Shares or of other equity or non-equity securities of the Issuer, depending upon price, market conditions, availability of funds, evaluation of alternative investments and other factors.  Without limiting the foregoing, the Reporting Persons’ intention generally is to explore means to realize favorable returns upon their investment in the Common Shares and accordingly, on an on-going basis, the Reporting Persons may seek, evaluate or respond to offers to sell or otherwise dispose of the Common Shares beneficially owned by them, either through open market or privately negotiated transactions.  The Reporting Persons reserve the right to take any action with respect to the Issuer or any of its equity securities or non-equity securities in any manner permitted by law.

The information previously provided and incorporated by reference in Item 3 is hereby incorporated by reference in this Item 4.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) Based upon the Issuer’s Quarterly Report on Form 10-Q, filed on November 9, 2012, there were 13,372,114 Common Shares outstanding as of November 8, 2012.

As of December 20, 2012, Whippoorwill may be deemed to be the beneficial owner of an aggregate of 4,776,341 Common Shares, representing 30.74% of the Common Shares. Of such beneficially owned Common Shares, 2,612,817 were held as Common Shares and 2,163,524 are issuable upon conversion of U.S. Concrete’s 9.5% Convertible Secured Notes (“Convertible Notes”). The calculation of the number of Common Shares issuable upon conversion of the Convertible Notes is based on the conversion price of $10.50 per share and $22,717,000 aggregate principal amount of Convertible Notes that may be deemed beneficially owned by Whippoorwill.

The Common Shares and Convertible Notes disclosed herein as beneficially owned by Whippoorwill are held for the account of various funds and third party accounts (the “Accounts”) for which Whippoorwill has discretionary authority and acts as general partner or investment manager.

Each of Mr. Greenhaus, as President and Principal of Whippoorwill, and Mr. Gendal, as Principal of Whippoorwill, may be deemed to beneficially own all the Common Shares and Convertible Notes beneficially owned by Whippoorwill.

(b) See Items 7 through 10 of the cover page for each Reporting Person.

(c) Not applicable.

(d) The Accounts have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Shares reported as beneficially owned by Whippoorwill. The following Accounts beneficially own more than 5% of the Common Shares: (1) WellPoint, Inc., an Indiana corporation, (2) Whippoorwill Distressed Opportunity Fund, L.P., a Delaware limited partnership; and (3) Whippoorwill Offshore Distressed Opportunity Fund, Ltd., a Cayman Islands exempted company limited by shares.

(e) Not applicable.

Item 6 of the Schedule 13D is hereby amended and supplemented to include the following:

Pursuant to the Exchange Agreement, Whippoorwill is obligated to tender all its Convertible Notes in the Exchange and may not transfer the Convertible Notes it currently holds outside of the Exchange Offer except as provided in the terms and conditions of the Exchange Agreement.

The foregoing description of the Exchange Agreement is qualified in its entirety by reference to the full text of the Exchange Agreement, which is attached as Exhibit B hereto and is incorporated herein by reference.
