1.4(d) in the event that Buyer achieves EBITDA equal to an amount set forth in column A on Schedule 1.4(d) during the fiscal year ending December 31, 2010 (the “2010 Performance Target”), the additional amount in Heckmann Common Stock set forth in column B on Schedule 1.4(d) (the “2010 Earn-Out”). 80% of the Heckmann Common Stock arising out of the 2010 Earn-Out shall be issued to the Members and 20% of the Heckmann Common Stock shall be issued to Silversword V, L.P.

1.5(b) Recipients shall have 15 days after the receipt of the Buyer EBITDA Schedule (the “Review Period”) to review the Buyer EBITDA Schedule and the EBITDA Calculation set forth therein. Recipients may elect to accept or object to the EBITDA Calculation set forth in the Buyer EBITDA Schedule by delivering a written notice of such acceptance (an “Acceptance Notice”) or of such objection in reasonable detail (an “Objection Notice”) to the Buyer prior to the expiration of the Review Period. If Recipients timely deliver an Acceptance Notice, the Buyer EBITDA Schedule and the EBITDA Calculation set forth therein shall be binding and conclusive upon the parties on the date of delivery of such Acceptance Notice. If Recipients timely deliver an Objection Notice, Recipients and Buyer will follow the procedures for resolution of disputes set forth in Section 1.5(d).

1.5(c) During the Review Period, Recipients will have the right to communicate with Buyer, and, to the extent reasonably required by Recipients to complete their review of the EBITDA

Calculation set forth in the Buyer EBITDA Schedule, review the work papers, books and records, schedules, memoranda and other documents Buyer prepared or reviewed in preparing the Buyer EBITDA Schedule and determining the EBITDA Calculation set forth therein.

1.5(d) If Recipients deliver an Objection Notice, then (i) for 20 days after the date Buyer receives the Objection Notice, Recipients and Buyer will use their best efforts to agree on the EBITDA Calculation, (ii) if the Buyers and Recipients are unable to agree on the EBITDA Calculation within such 20 day period, the matter will be referred to a mutually agreed upon independent national accounting firm (the “Accounting Firm”) for determination, and (iii) any Heckmann Common Stock arising out of the 2010 Earn-Out or 2011 Earn-Out, as applicable, will be issuable no later than the later to occur of (A) March 31, or (B) 5 days after the Objection Notice is resolved pursuant to this Section 1.5(d). The Accounting Firm shall act as an arbitrator to determine, based solely upon the provisions of this Agreement and the submissions of Buyer and Recipients, and not by independent review, those issues in dispute. The Accounting Firm shall deliver a written report within 15 days of its appointment setting forth its determination of the EBITDA Calculation and, upon the issuance of such report, the Accounting Firm’s determination shall be binding and conclusive upon the parties. The fees and expenses of the Accounting Firm shall be shared equally by Buyer and Recipients.

Any Heckmann Common Stock issuable to the Members that arises out of the First Earn-Out Accelerated Amount shall be allocated among the Members as set forth on Schedule 1.4. The number of shares of Heckmann Common Stock comprising the First Earn-Out Accelerated Amount shall be computed at the average of the closing market price on the New York Stock Exchange, or such other national securities exchange on which Heckmann Common Stock may then be listed, for the last ten trading days immediately prior to the consummation of the Earn-Out Acceleration Event. Notwithstanding the foregoing, if the Earn-Out Acceleration Event giving rise to the obligation to deliver the First Earn-Out Accelerated Amount occurs subsequent to December 31, 2010 and (A) the 2010 Performance Target has not been achieved, or (B) Heckmann has issued the Heckmann Common Stock arising out of the 2010 Earn-Out, then the First Earn-Out Accelerated Amount shall be reduced by $5.0 million. Any Heckmann Common Stock arising out of the First Earn-Out Accelerated Amount shall be issued by Heckmann within two business days after the later of (y) the consummation of the Earn-Out Acceleration Event giving rise to the obligation to deliver the First Earn-Out Accelerated Amount, and (z) final resolution of the EBITDA Calculation for fiscal year 2010 pursuant to Section 1.5, subject to Section 8.7. In any event, if an Earn-Out Acceleration Event has not occurred prior to March 31, 2011, this Section 1.6(a) will terminate and be of no further effect.

1.6(b) If, subsequent to March 31, 2011 and prior to March 31, 2012, an Earn-Out Acceleration event occurs, then Heckmann will issue and deliver $5.0 million in Heckmann Common Stock (the “Second Earn-Out Accelerated Amount”) as follows: 80% of the Heckmann Common Stock arising out of the Second Earn-Out Accelerated Amount shall be issued to the Members and 20% of such Heckmann Common Stock shall be issued to Silversword V, L.P. Any Heckmann Common Stock issuable to the Members that arises out of the Second Earn-Out Accelerated Amount shall be allocated

among the Members as set forth on Schedule 1.4. The number of shares of Heckmann Common Stock comprising the Second Earn-Out Accelerated Amount shall be computed at the average of the closing market price on the New York Stock Exchange, or such other national securities exchange on which Heckmann Common Stock may then be listed, for the last ten trading days immediately prior to the consummation of the Earn-Out Acceleration Event. Notwithstanding the foregoing, if the Earn-Out Acceleration Event giving rise to the obligation to deliver the Second Earn-Out Accelerated Amount occurs subsequent to December 31, 2011 and (A) the 2011 Performance Target has not been achieved, or (B) Heckmann has issued the Heckmann Common Stock arising out of the 2011 Earn-Out, then Heckmann shall have no obligation to deliver the Second Earn-Out Accelerated Amount. Any Heckmann Common Stock arising out of the Second Earn-Out Accelerated Amount shall be issued by Heckmann within two business days after the later of (y) the consummation of the Earn-Out Acceleration Event giving rise to the obligation to deliver the Second Earn-Out Accelerated Amount, and (z) final resolution of the EBITDA Calculation for fiscal year 2011 pursuant to Section 1.5, subject to Section 8.7. In any event, if an Earn-Out Acceleration Event has not occurred prior to March 31, 2012, this Section 1.6(b) will terminate and be of no further effect.

1.7 Other Consideration. In addition to the foregoing, Buyer shall assume the Assumed Liabilities (as defined in Section 1.10), and shall reimburse Silversword at Closing for up to $300,000 of the amounts outstanding and advanced by it, if any, related to the Construction Project, including all amounts paid or incurred by Silversword for rights-of-way and construction materials, which amounts are set forth on Schedule 1.7.

1.8 Stock Limitation. In no event, under any circumstances, shall the Heckmann Common Stock to be issued under this Agreement exceed 19.9% of the common stock outstanding as of the Closing.

1.9 Purchase Price Review and Adjustments. In the event that, prior to the Closing, Buyer discovers any breach of any representation, warranty or agreement of Sellers or Owners, including any defect in title to the Purchased Assets, environmental hazard, violation of Environmental Laws or Saltwater Disposal Laws, failure to maintain the Purchased Assets (including the Contracts and Land Use Rights), failure to pay contractors timely, or otherwise, then Buyer shall have the option to (a) reduce the Cash Consideration by the amount necessary to cure any breaches, defaults or defects, which amount shall be subject to the post-closing dispute procedures in Section 1.5(d), or (b) terminate this Agreement under Section 9.1(f). Nothing herein shall relieve Sellers or Owners from, or constitute a waiver by Buyer of, any of their representations, warranties or obligatons under this Agreement, except only to the extent paid for by Sellers as provided in Section 1.9(a). If the amount required to cure all breaches, defaults and defects is in excess of $250,000, and if a Seller does not want to adjust the Purchase Price, the Seller may terminate this Agreement. Notwithstanding the foregoing, there shall be no purchase price adjustment in any amount related to the condition of the Existing Wells and Existing Pipelines except as may be agreed by Silversword.

1.10 Limited Assumption of Liabilities.

5.2 No Shop. No Seller, Owner, or any director, officer, manager or agent of any Seller, shall solicit, entertain or negotiate with respect to any offers for any of the capital stock or other equity interests of any Seller or (except in the Ordinary Course of Business) any of the properties or assets of any Seller prior to the earlier of the termination of this Agreement in accordance with its terms or the

5.3 Access to Information. Sellers shall make available to Buyer, its attorneys, accountants and representatives all records, books of account, documents and information (and shall cooperate with Buyer in communicating with relevant third parties) so that Buyer may investigate any and all aspects of the business, prospects, properties, assets, reserves and financial condition of Sellers.

Buyer will prepare a preliminary purchase price allocation schedule for review prior to Closing.

5.7 Transitional Matters. Without further consideration, Sellers and Owners shall take all such actions and execute all such documents as may be necessary or appropriate to effect an orderly transition of the ownership and operation of the Purchased Assets or of the Charis Equity, as applicable. Without limitation of the foregoing, Sellers and Owners shall reasonably assist Buyer in notifying customers, suppliers, employees and other interested third parties, in attaining all necessary consents to the transactions contemplated hereby and in making appropriate transfers of the Governmental Authorizations listed on Schedule 1.1(h). Pending such transfers, Greer and Silversword hereby grant Buyer, as of the Effective Time, the exclusive use of all of their respective Governmental Authorizations to the extent such Sellers can grant such use.

5.8 Buyer Operation of Business. Following the Effective Time through December 31, 2011, Buyer shall use commercially reasonable efforts to conduct the Business in the Ordinary Course of

Business and not operate the Business in a manner intended to avoid achievement of the 2010 Performance Target or the 2011 Performance Target; provided, however, that nothing in this Section 5.8 is intended to or shall (a) limit the Buyer in any way in the exercise of its business judgment in operating the Business in a commercially reasonable manner following the Effective Time, (b) require the Buyer to continue any line of business conducted by the Business as of any date if the Buyer, in the exercise of its reasonable business judgment, believes that it is not commercially reasonably to continue such line of business, or (c) limit the Buyer from modifying any aspect of the Business in the exercise of its reasonable business judgment.

5.9 Heckmann Public Information. Heckmann will use commercially reasonable efforts to satisfy SEC Rule 144(c) or any successor SEC rule.

5.10 Non-Competition and Non-Solicitation.

5.10(a) For a period of three years (the “Restricted Period”), none of the Stockholder or the Members will, without the prior written consent of Buyer in its sole and absolute discretion, either alone or jointly with or on behalf of any Person, directly or indirectly, carry on or set up, or be employed or engaged by or in, or otherwise assist or be interested in, in any capacity (except as a stockholder of not more than three percent of the shares of any company whose shares are publicly traded on a national securities exchange), or disclose any trade secret, intellectual property, customer list, or other confidential or other information about the Business to, a business that is carried on in competition with the Business anywhere within the States of Texas and Louisiana (the “Restricted Area”).

5.10(b) During the Restricted Period, none of Greer, Silversword, the Stockholder or Members will, without the prior written consent of Buyer in its sole and absolute discretion, either alone or jointly with or on behalf of any Person, directly or indirectly, (i) solicit any customers or suppliers of the Business, (ii) solicit for employment, hire, or engage for services any Person employed or engaged by the Buyer after the Closing (or that was so employed or engaged during the 6-month period prior to the anticipated hiring).

5.10(c) The covenants contained in this Section 5.10 are intended to be separate and severable and enforceable as such, and to be enforceable to the fullest extent permissible under the laws of each jurisdiction in which enforcement is sought. If any restriction contained in this Section 5.10 is for any reason held by a court or arbitration tribunal to be excessively broad as to duration, activity, geographical scope, or subject, then such restriction shall be construed, reformed or judicially modified, as necessary in such jurisdiction so as to thereafter be limited or reduced to the extent required to be enforceable in such jurisdiction in accordance with applicable Legal Requirements. If any restriction in this Section 5.10 is held to be invalid, illegal or unenforceable in any respect under any applicable Legal Requirements in any jurisdiction, then such invalidity, illegality or unenforceability will not affect any other provision of this Section 5.10, but such restriction will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable restriction had never been contained in this Section 5.10.

5.10(d) Greer, Silversword, Stockholder and Members acknowledge that the remedy at law for their breach of this Section 5.10 will be inadequate, and that the damages flowing from such breach will not be readily susceptible to being measured in monetary terms. Accordingly, upon a breach or threatened breach of this Section 5.10, Buyer will be entitled to immediate injunctive relief (or other equitable relief) and may obtain a temporary order restraining any breach or further breach. No bond or other security will be required to obtain such relief, and Greer, Silversword, Stockholder and Members consent to the issuance of such equitable relief. Nothing in this Section 5.10(d) will be deemed to limit

Buyer’s remedies at law or in equity that may be pursued or availed of by Buyer for any breach or threatened breach by any of Greer, Silversword, Stockholder or Members of any part of this Section 5.10.

5.10(e) The covenants contained in this Section 5.10 have been agreed to by Buyer, the Greer, Silversword, Stockholder and Members to be reasonable and in exchange for reasonable and mutually agreed consideration, including consideration under this Agreement and under employment agreements between Buyer on the one hand, and the Stockholder and the Members on the other hand. The Business is highly competitive, the terms of this Section 5.10 are material to the willingness of Buyer, Greer, Silversword, Stockholder and Members to enter into this Agreement, and the terms and conditions of this Section 5.10 are not more restrictive than is necessary to protect the legitimate interests of Buyer.

5.11 Transfer of Land. Silversword IV, L.P. shall acquire fee simple title to the Land, save and except any interest in oil, gas and other minerals in and under the Land, prior to the Closing, and, as of the Closing, shall have exclusive possession and Defensible Title to the Land, free and clear of all Liens.

5.12 Sellers’ Representations and Warranties. Heckmann shall advise Sellers if, prior to the Closing, Richard J. Heckmann or Donald G. Ezzell have actual knowledge of a breach by any Seller or Owner of any representation or warranty made herein that would result in Losses (as defined in Section 8.1) in excess of $150,000. For purposes of this Section 5.12, Richard J. Heckmann and Donald G. Ezzell shall be deemed to have actual knowledge of information that is specifically disclosed in the Disclosure Schedule. Their actual knowledge shall not include any imputation of knowledge, such as the knowledge that would arise by reasonable or other investigation, or the knowledge that could be gleaned from information provided to Heckmann by Sellers or Owners, unless the information provided clearly identifies the issue and potential Losses and is in fact understood by Richard J. Heckmann and Donald G. Ezzell.

5.13 Forms P-4. Within five business days after the Effective Time, Buyer shall file original Forms P-4 with the Texas Railroad Commission that effectively transfer operatorship of the Existing Wells to Buyer as of the Effective Time.

8.1(a) any breach or failure to satisfy any of the covenants, agreements, warranties or representations of such Seller Party contained in this Agreement provided that, with respect to the representations and warranties in the second sentence of Section 3.7(b) (but only to the extent that such representations and warranties relate to the Wells, the Pipeline and related equipment), the Owners shall be deemed to make them solely as to their Knowledge.

8.1(b) the liabilities or potential liabilities of such Seller Party described in the Disclosure Schedule.

8.1(c) the ownership and operation of the Business, Purchased Assets or Charis Equity relating to the period prior to the Effective Time.

Buyer, on its behalf and on behalf of its successors and assigns, agrees to defend, indemnify and hold the Seller Parties, and their respective Affiliates, stockholders or other equity holders, directors, managers, officers, employees and agents harmless from and against any and all Losses to which they or any of them become subject due to, or which results from, any of the following:

8.2(a) any breach or failure to satisfy any of the covenants, agreements, warranties or representations of Buyer or Heckmann contained in this Agreement.

8.2(b) the ownership and operation of the Business, Purchased Assets, or Charis Equity relating to the period after the Effective Time.

8.2(c) The liabilities, obligations and commitments of Greer and Silversword expressly assumed by Buyer hereunder.

8.3 Procedure for Indemnification. The party that is entitled to be indemnified hereunder (the “Indemnified Party”) by the party required to indemnify hereunder (the “Indemnifying Party”) shall follow the procedures set forth below.

8.3(a) The Indemnified Party will promptly give notice hereunder to the Indemnifying Party after obtaining notice of any claim as to which recovery may be sought against the Indemnifying Party. However, the right to indemnification hereunder will not be affected by any delay in or failure of an Indemnified Party to give any notice, unless, and then only to the extent that, the rights and remedies of the Indemnifying Party will have been prejudiced as a result of the failure to give, or delay in giving, notice.

8.3(b) If the indemnity claim arises from the claim of a third-party who is not then doing business with the Buyer, the Indemnified Party will permit the Indemnifying Party to assume the defense of any such claim and any litigation resulting from such claim. If the Indemnifying Party fails to notify an Indemnified Party of its election to defend any such claim or action by a third party with respect to which it has the option to defend within 30 days after the Indemnifying Party receives notice of such claim or action, then the Indemnifying Party will be deemed to have waived its right to defend such claim or action. If the Indemnifying Party assumes the defense of a third-party claim, the obligations of the Indemnifying Party as to such claim will include taking all steps necessary in the defense or settlement of such claim or litigation and holding the Indemnified Party harmless from and against any and all damages caused by or arising out of any settlement approved by the Indemnifying Party or any judgment in connection with such claim or litigation. The Indemnifying Party shall not, in the defense of such claim or any litigation resulting therefrom, consent to entry of any judgment (other than a judgment of dismissal on the merits without costs) except with the written consent of the Indemnified Party, or enter into any settlement (except with the written consent of the Indemnified Party) which does not include as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a release from all liability in respect of such claim or litigation. The non-defending party may, with counsel of its choice and at its expense, participate in the defense of any such claim or litigation.

8.3(c) If the Indemnifying Party does not assume the defense of any such claim or litigation by a third-party, the Indemnified Party may defend against such claim or litigation in such manner as it deems appropriate. Unless the Indemnifying Party deposits with the Indemnified Party a sum equivalent to the total amount demanded in such claim or litigation plus the Indemnified Party’s estimate of the costs of defending the same, the Indemnified Party may settle such claim or litigation on such terms as it may deem appropriate and the Indemnifying Party will promptly pay or reimburse the Indemnified Party for all expenses in defending any claim, for the amount of any settlement, and for all damages incurred by the Indemnified Party in connection with such claim or litigation.

8.4 Control of Claims and Remedial Work. Notwithstanding the foregoing, in the event any liability or condition for which Buyer may seek indemnification hereunder requires the performance of any investigatory, reclamation or remedial work, or in the event that any claim relates to a Person with whom Buyer maintains an ongoing relationship, then Buyer shall conduct and control the work or defense of the claim, as the case may be, at the expense of the Seller Parties, subject to their consent to any monetary settlement in excess of $50,000 pertaining thereto, which consent shall not be unreasonably withheld.

8.5 Limitation of Liability. No claim for Losses may be brought under this Section 8 unless and until the aggregate amount of all claims for Losses of an Indemnified Party is at least $150,000 (the

“Indemnification Threshold”) whereupon all claims (from dollar one) for Losses of such Indemnified Party may be brought by such Indemnified Party. The Indemnification Threshold will not apply to Losses (a) giving rise to a reduction of the Cash Consideration pursuant to Section 1.9(a), or (b) relating to any contingent liabilities that are disclosed, or that should have been disclosed, on the Disclosure Schedule pursuant to Section 3. Notwithstanding anything else in this Agreement, the liability of each Seller Party under this Section 8 shall be limited to the value of the consideration received by such Seller Party under this Agreement, absent fraud or knowing misrepresentation or omission. Heckmann or Buyer may only seek recovery for Losses against the Seller Parties responsible therefor, provided that it may pursue any Seller Party if it is not patently clear that the Loss is attributable to the representations, warranties, covenants, agreements, indemnities for actions or omissions of particular Seller Parties, unless specific Seller Parties admit in writing responsibility for the Loss (or, reserving their rights, admit that if there is a Loss that is subject to recovery, that they would be the responsible party), it is logical that such party would be the responsible party, and such party has the wherewithal to fund any Loss. Each Seller Party shall be jointly and not severally liable as to the representations, warranties and agreements that apply to their entity or an Owner thereof.

8.6 Equitable Remedies. Each party acknowledges that their rights under this Agreement are special, unique and of an extraordinary character and that such party could not be adequately compensated by money damages for a breach of the provisions of this Agreement by the other party. In the event this Agreement is breached, the other party shall be entitled to an injunction restraining such breach (or any threatened breach) and to specific performance of any provision of this Agreement, without bond or other security therefor, in addition to any other right or remedy available to such party.

8.7 Offset.
