compensation in the event the undersigned, any member of the family of the undersigned or any Affiliate of the undersigned originates a Business Combination.

 SECURITIES ESCROW AGREEMENT 
 THIS SECURITIES ESCROW AGREEMENT, dated as of
                        , 2007 (this “Agreement”), by and among Heckmann Corporation, a Delaware
corporation (the “Company”), each of the parties set forth on Exhibit A annexed hereto (collectively the “Private Investors”) and American Stock Transfer & Trust Company (the “Escrow
Agent”). 
 WHEREAS, the Company has entered into an Underwriting Agreement, dated
                        , 2007 (the “Underwriting Agreement”), with Credit Suisse Securities (USA) LLC
(“Credit Suisse”) and Roth Capital Partners, LLC acting as underwriters (collectively, the “Underwriters”), pursuant to which, among other matters, the Underwriters have agreed to purchase 50,000,000 units of the
Company plus an additional 7,500,000 units if the Underwriters exercise their over-allotment option in full. The Company’s units (the “Units”) each consist of one share of the Company’s common stock, par value $0.001 per share
(the “Common Stock”), and one warrant (the “Warrant”) exercisable to purchase one share of Common Stock, all as more fully described in the Company’s final Prospectus, dated __________, 2007, comprising part of
the Company’s Registration Statement on Form S-1 (File No. 333-144056) (the “Registration Statement”) filed under the Securities Act of 1933, as amended, and declared effective by the Securities and Exchange Commission on
                        , 2007 (the “Effective Date”); 
 WHEREAS, each of the Private Investors has agreed as a condition of the Underwriters’ purchase of the Units to deposit its Units purchased on
June 21, 2007, as set forth opposite each Private Investor’s name on Exhibit A attached hereto (the “Founders’ Units”), in escrow as hereinafter provided; 
 WHEREAS, the Private Investors have agreed as a condition of the Underwriters’ purchase of the Units to purchase an aggregate of 7,000,000 Warrants
for $1.00 per Warrant (the “Sponsors’ Warrants” and, collectively with the Founders’ Units, the shares of Common Stock underlying the Founders’ Units and the Warrants underlying the Founders’ Units, the
“Escrow Securities”) immediately prior to and subject to the Closing and to deposit such Sponsors’ Warrants in escrow as hereinafter provided; and 
 WHEREAS, the Company and the Private Investors desire that the Escrow Agent accept the Escrow Securities, in escrow, to be held and disbursed as hereinafter provided. 
 IT IS AGREED: 
 1. Appointment of Escrow Agent. The
Company and the Private Investors hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such
terms. 
  

	2.	 	Deposit of Escrow Securities. 

 2.1.
Founders’ Units. On or before the Effective Date, each of the Private Investors shall deliver to the Escrow Agent certificates representing such Private Investor’s respective Founders’ Units as set forth opposite their
respective names on Exhibit A hereto, which certificates shall remain in the name of such Private Investor, to be held and disbursed subject to the terms and conditions of this Agreement. Each Private Investor acknowledges that the certificate
representing such Private Investor’s Founders’ Units bears a legend to reflect the deposit of such Founders’ Units under this Agreement. 
  

 1 

 2.2 Private Placement Securities. Promptly following the consummation of the Offering, each of the
Private Investors shall deliver to the Escrow Agent certificates representing such Private Investor’s respective Sponsors’ Warrants as set forth opposite their respective names on Exhibit A attached hereto, which certificates shall remain
in the name of such Private Investor or such Private Investor’s Permitted Transferee, as applicable, to be held and disbursed subject to the terms and conditions of this Agreement. Each Private Investor acknowledges that the certificates
representing such Private Investor’s Sponsors’ Warrants shall bear a legend to reflect the deposit of such securities under this Agreement. 
 3. Disbursement of the Escrow Securities. The Escrow Agent shall hold the Founders’ Units until the
first anniversary of the consummation of a Business Combination (as such term is defined in the Amended and Restated Articles of Incorporation of the Company) and shall hold the Sponsors’ Warrants until the 90th day after the consummation of a Business Combination (each such period, an “Escrow Period”); provided, however, that if the over-allotment granted to the
Underwriters pursuant to the Underwriting Agreement is not exercised in full prior to the expiration of the over-allotment option, then the Escrow Agent shall release to the Company such number of Founders’ Units as directed in writing by the
Company. The Company shall promptly provide notice of the consummation of a Business Combination to the Escrow Agent. Upon the completion of each Escrow Period, the Escrow Agent shall automatically disburse the applicable Escrow Securities to each
Private Investor upon receipt of written request therefor from the Company; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company has been liquidated at any time during the
Escrow Period, then the Escrow Agent shall promptly destroy the certificates representing the Escrow Securities; provided further, however, that if the consummation of a Business Combination takes the form of a merger, stock exchange or other
similar transaction which results in any of the security holders of the Company having the right to exchange their securities for other securities, then the Escrow Agent shall, upon receipt of a certificate in form reasonably acceptable to the
Escrow Agent, executed by the Chief Executive Officer of the Company, release the Escrow Securities to the Private Investors immediately prior and subject to consummation of the Business Combination so that they can similarly participate, and upon
receipt of the securities issued in respect thereof in connection with the Business Combination, the Private Investors shall deposit such securities into escrow with the Escrow Agent for the remainder of the applicable Escrow Periods; and
provided further, however, that if, after the Company consummates a Business Combination and the Company or the surviving entity of such Business Combination subsequently consummates a liquidation, merger, stock exchange or other similar
transaction which results in any of the security holders of the Company or such entity having the right to exchange their securities for cash, securities or other property, then the Escrow Agent shall, upon receipt of a certificate in form
reasonably acceptable to the Escrow Agent, executed by the Chief Executive Officer of the Company, that such transaction is then being consummated, release the Escrow Securities to the Private Investors immediately prior and subject to consummation
of the transaction so that they can similarly participate. The Escrow Agent shall act as soon as reasonably possible following the receipt of the certificate, and shall not be held liable for any delay in sending the Escrow Securities caused by the
late receipt of the certificate. The Escrow Agent shall have no further duties hereunder with respect to the Escrow Securities after the disbursement or destruction of the Escrow Securities in accordance with this Section 3.

the terms of this Agreement. 
 4.2. Dividends and other Distributions in Respect of the Escrow Securities. During the Escrow Period
with respect to the Escrow Securities, all dividends payable in cash with respect to the Escrow Securities shall be paid to the Private Investors, but all dividends payable in stock or other non-cash property (the “Non-Cash

which is the Private Investor or a member of the Private Investor’s immediate family, (ii) if the Private Investor is not a natural person, by gift to a member of the immediate family of such Private Investor’s controlling person for
estate planning purposes or to a trust, the beneficiary of which is such Private Investor’s controlling person or a member of the immediate family of such Private Investor’s controlling person, (iii) by virtue of the laws of descent
and distribution upon death of the Private Investor, or (iv) pursuant to a qualified domestic relations order (each such transferee, a “Permitted Transferee”); provided, however, that such permitted Transfers may be
implemented only upon the respective Permitted Transferee’s written agreement to be bound by the terms and conditions of this Agreement and of the Insider Letter signed by such Private Investor transferring such Escrow Securities and such other
documents as the Company or Credit Suisse may reasonably require. During the Escrow Period, no Private Investor shall pledge or grant a security interest in such Private Investor’s Escrow Securities or grant a security interest in such Private
Investor’s rights under this Agreement.

relates to this Agreement, the services of the Escrow Agent hereunder, or the Escrow Securities held by it hereunder, other than expenses or losses arising from the gross negligence or willful misconduct of the Escrow Agent. Promptly after the
receipt by the Escrow Agent of notice of any demand or claim or the commencement of any action, suit or proceeding, the Escrow Agent shall notify the other parties hereto in writing. In the event of the receipt of such notice, the Escrow Agent, in

the Escrow Agent may submit an application to deposit the Escrow Securities with the United States District Court for the Southern District of New York, provided the Escrow Agent provides notice of such deposit to the Company and the Private
Investors in accordance with Section 6.7 hereof. 
 5.6. Discharge of Escrow Agent. The Escrow Agent shall resign and be
discharged from its duties as escrow agent hereunder if so requested in writing at any time by the other parties hereto, jointly; provided, however, that such resignation shall become effective only upon acceptance of appointment by a
