EXHIBIT 10.40

EXCHANGE AND CONSENT AGREEMENT

This EXCHANGE AND CONSENT AGREEMENT (this “Agreement”) is dated December 20, 2012, by and between U.S. Concrete, Inc., a Delaware corporation (the “Company”), and each of the persons listed on Schedule I attached hereto as beneficial owners of the Notes referred to below (together with their respective successors, transferees and assigns, each a “Noteholder” and, collectively, the “Noteholders”).

WHEREAS, the Company desires to exchange (the “Exchange”) those certain 9.5% Convertible Secured Notes due 2015 (the “Notes”) issued pursuant to the Indenture, by and among the Company, the guarantors party thereto, and U.S. Bank National Association, as Trustee and Noteholder Collateral Agent (the “Trustee”), dated as of August 31, 2010 (the “Indenture”) for 9.5% Senior Secured Notes due 2015 (the “Exchange Notes”) on substantially the same terms as the terms described in the term sheet (the “Term Sheet”) attached hereto as Exhibit A;

WHEREAS, in order to facilitate the Exchange, the Company intends to deliver, in writing, to each holder of the Notes an Offer to Exchange and Consent Solicitation (the Solicitation”) offering the opportunity to it to tender its Notes in the Exchange and consent to the amendment of the Indenture, in accordance with the Term Sheet (the “Amendment”);

WHEREAS, in anticipation of the Solicitation, the Company desires to enter into this Agreement with the Noteholders, in order to, among other things, obtain their agreement to tender their Notes in the Exchange;

WHEREAS, the Noteholders desire to enter into this Agreement and confirm their agreement to tender their Notes in the Exchange and consent to the Amendment, subject to the terms and conditions hereof; and

WHEREAS, each of the Company and the Noteholders has reviewed, or has had the opportunity to review, with the assistance of professional and legal advisors of their choosing, the proposed terms of the transactions contemplated in the Term Sheet.

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained and intending to be legally bound, the parties hereto hereby agree as follows:

ARTICLE I.

THE EXCHANGE; AMENDMENT

Section 1.01    Exchange Offer. Each of the Noteholders agrees that, subject to any limitations in the Indenture, if this Agreement has not been terminated in accordance with its terms, it shall (i) within five (5) Business Days from the date it receives the written Solicitation materials complying with this Agreement, tender or cause to be tendered all of its Notes in the Exchange and

will not withdraw any of such Notes from the Exchange prior to the earlier of (A) the expiration of the Exchange or (B) the termination of this Agreement in accordance with its terms, (ii) vote to amend the Indenture and adopt the Amendment pursuant to the Solicitation, (iii) refrain from, directly or indirectly, supporting or consenting to any competing exchange offer, consent solicitation or similar transaction in respect of the Notes other than the Exchange and Solicitation, and (iv) not instruct or cause the Trustee to take any action that is inconsistent with the terms and conditions of this Agreement. The Company shall prepare the Solicitation, the Amendment and the other documents to be distributed to holders of the Notes in connection with the Exchange and any document required to be filed with the Securities and Exchange Commission (the “SEC”), including any registration statements required to be filed under the Securities Act of 1933, as amended, which documents shall be in form and substance reasonably satisfactory to the Noteholders and, except as otherwise may be consented to in writing by each of the Noteholders, consistent in all material respects with the Term Sheet and the terms of this Agreement. Each Noteholder shall, with reasonable promptness upon request by the Company, furnish to the Company all information about itself and its affiliates reasonably necessary or appropriate for inclusion in any documents prepared by the Company in connection with the Solicitation or otherwise distributed to holders of the Notes in connection with the Exchange or required to be filed with the SEC in connection therewith, including any registration statements required to be filed under the Securities Act of 1933, as amended, and hereby covenants that any such information furnished in writing by such Noteholder to the Company for inclusion in such documents shall be true and accurate in all material respects as of the time such information is provided, and shall promptly notify the Company in writing if any such information subsequently becomes untrue or inaccurate in any material respect. Each Noteholder agrees, so long as this Agreement remains in effect, that the Solicitation materials may reference the existence of this Agreement and similar agreements with other holders of Notes, provided however that such Noteholder may not be named or otherwise identified without the prior written consent of such Noteholder unless required by law or by a judicial, administrative, legislative or regulatory body. The Company covenants and represents and warrants that no exchange and consent agreement, or other agreement concerning the transactions contemplated hereby, with any other holder of Notes shall be more beneficial to such holder than the terms and conditions of this Agreement are to the Noteholders. If this Agreement is terminated in accordance with its terms prior to the consummation of the Exchange, the Company shall take all steps necessary to permit the Noteholders to withdraw the tender of their Notes and revoke all consents given pursuant to this Agreement and the Solicitation and shall treat such tenders and consents as having not been given.

Section 1.02    Prohibition on Transfer of Notes. Each Noteholder agrees that, during the term of this Agreement, it shall not sell, assign, pledge, transfer or otherwise dispose, nor permit the sale, assignment, pledge, transfer or other disposition, of the Notes it beneficially owns, in whole or in part, or any interest therein, other than to tender them pursuant to the Exchange, unless the transferee thereof accepts such Notes subject to this Agreement and agrees in writing to be bound by the terms of this Agreement as a Noteholder, and such writing is provided to the Company promptly. Furthermore, each Noteholder agrees that, during the term of this Agreement, any additional Notes that such Noteholder acquires, purchases or otherwise beneficially owns shall be subject to this Agreement. For the avoidance of doubt, “beneficially owns” means the power, whether by contract or otherwise, to direct the exercise of the voting rights and the disposition of

2

the Notes or the right to acquire such rights for no additional consideration within one Business Day, including without limitation pursuant to the terms of a swap agreement. “Business Day” means any day of the year other than a Saturday or Sunday or any day on which the Federal Reserve Bank of New York is closed.

Section 1.03    Conditions; Waiver of Conditions. The obligation of the Company to accept for exchange Notes properly tendered pursuant to the Exchange shall be subject to only the following conditions (the “Conditions”): (i) not less than 82.5% in outstanding principal amount of the Notes having been validly tendered and not withdrawn on or prior to the expiration time for the Exchange, (ii) the Amendment having been executed and being effective, (iii) any registration statement required under the Securities Act of 1933, as amended, in respect of the Exchange having been declared effective by the SEC and the indenture governing the Exchange Notes having been qualified under the Trust Indenture Act of 1939, as amended, and (iv) no order, statute, rule, regulation, executive order, stay, decree, judgment or injunction shall have been enacted, entered, issued, promulgated or enforced by any court or governmental authority that prohibits the consummation of the Exchange on, or consistent with, the terms and conditions of this Agreement shall have occurred and remain in effect. The Company shall use its commercially reasonable best efforts to ensure that each of the Conditions is satisfied in connection with the Exchange. The Company shall not (i) waive any of the foregoing conditions to the consummation of the Exchange or (ii) amend any of the terms or conditions of the Exchange or the form of Amendment approved by the Noteholders or (to the extent the Noteholders have elected to review and approve such portion of the Solicitation materials) other portions of the Solicitation materials relating to the terms and conditions of the Exchange approved by the Noteholders, in each case without the prior written consent of each of the Noteholders.

Section 1.04    Mutual Assurances. The Company and the Noteholders hereby covenant to one another to use their commercially reasonable best efforts, as expeditiously as possible and during the term of this Agreement, to perform their respective obligations under this Agreement and take such actions as may be reasonably necessary under this Agreement to consummate the Exchange. The parties further agree to take such other actions as are reasonably necessary and appropriate to carry out the foregoing and to effectuate the Exchange and evidence the Noteholders’ support of the Exchange and the Amendment including, but not limited to, the execution and delivery of any transmittal letters, written consents or other similar documents containing customary terms and provisions.

ARTICLE II.

(v) upon the occurrence of a Material Event; or

(vi) upon the occurrence or during the occurrence of an Event of Default under and as defined in the Indenture; or

(d)    as to any particular Noteholder, upon the transfer of all Notes subject to this agreement by such Noteholder pursuant to and in accordance with Section 1.02 of this Agreement; or

As used herein, “Material Event” means (i) the Company’s entry into of, or any agreement of the Company providing for, any individual transaction, or series of related transactions for (x) the acquisition of assets or equity securities of another person, or a merger with another person, in which the aggregate consideration for the transaction or series of related transactions is $25 million or more or (y) the disposition of assets of the Company or its subsidiaries in which the aggregate consideration for the transaction or series of related transactions is $25 million or more or (ii) the occurrence of, or the entry into of an agreement providing for, or the announcement by the Company of, a Specified Change of Control. As used herein, “Specified Change of Control” means:

(i)           The Company consolidates with or merges with or into another Person, or the Company sells, conveys, transfers or leases all or substantially all of its properties and assets to any Person;

(ii)          Any “person” or “group” is or becomes the “beneficial owner,” directly or indirectly, of more than 50% of the total voting power in the aggregate of all classes of the Company’s capital stock then outstanding and entitled to vote generally in elections of directors; provided, however, that (x) with respect to any “person,” such “person” is neither a Noteholder nor a person that has entered into a separate exchange and consent agreement with the Company on or about the date hereof with respect to the subject matter hereof, and (y) with respect to any “group,” such “group” does not include any of the “persons” set forth in the foregoing clause (x)

As conditions to the Exchange, (i) the lenders under Issuer’s Loan and Security Agreement (the “ABL Facility”), dated as of August 31, 2012, among Issuer, certain of its subsidiaries, the lenders party thereto and Bank of America, N.A. as agent (the “ABL Facility Agent”) must consent to the transactions and (ii) the ABL Facility Agent must consent to the amendment to the Intercreditor Agreement. The Exchange Offer shall include exit consents (subject to successful completion of the Exchange Offer) to strip all collateral and substantially all of the negative covenants and certain other provisions from the indenture governing the Existing Notes not tendered into the Exchange Offer and such other changes as Issuer determines are desirable to maximize participation in the Exchange Offer.
