Agreement”) proposed to be entered into by and among Heckmann Corporation, a Delaware corporation (the “Company”), Credit Suisse Securities (USA) LLC, Roth Capital Partners, LLC and Morgan Joseph & Co. Inc. (together,
the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of the Company’s units (the “Units”), each Unit comprised of one share of the Company’s Common Stock,
par value $0.001 per share (the “Common Stock”), and one warrant, which is exercisable for one share of Common Stock. Certain capitalized terms used herein are defined in paragraph 13 hereof. 
 In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the
benefit that such IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company and
the Underwriters as follows: 
 1. If the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all Insider
Shares owned by the undersigned in accordance with the majority of the votes cast by the holders of the IPO Shares. The undersigned will not vote in favor of any amendment to Articles Fifth and Sixth of the Amended and Restated Certificate of
Incorporation of the Company proposed to be filed with the Secretary of State of the State of Delaware on the Effective Date. 
 2. In the event that the
Company fails to consummate a Business Combination within twenty four (24) months from the effective date (the “Effective Date”) of the Registration Statement, the undersigned will take all reasonable actions within the
undersigned’s power to (i) cause the Trust Account to be liquidated and distributed to the holders of IPO Shares in accordance with that Investment Management Trust Agreement to be entered into by and between the Company and American Stock
Transfer & Trust Company, as Trustee (the “Trust Agreement”); and (ii) cause the Company to liquidate as soon as reasonably practicable. The undersigned agrees that in connection with any cessation of the corporate
existence of the Company, he will take all reasonable steps to cause the Company to adopt a plan of distribution in accordance with Section 281(b) of the General Corporation Law of the State of Delaware or any successor provision thereto. The
undersigned hereby waives any and all right, title, interest or claim of any kind (each a “Claim”) in or to (x) any distribution of the Trust Account with respect to the undersigned’s Insider Shares in connection with a
liquidation and (y) any remaining net assets of the Company after such liquidation. The undersigned hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts 








 
or agreements with the Company and will not seek recourse against the funds held in or distributed from the Trust Account for any reason. The undersigned
acknowledges and agrees that there will be no distribution from the Trust Account with respect to any warrants, all rights of which will terminate on the Company’s liquidation. 
 3. Except as disclosed in the Registration Statement, none of the undersigned, any member of the family of the undersigned, nor any Affiliate of the undersigned will be entitled to receive and will not accept any
