WHEREAS, Nuverra Environmental Solutions, Inc., a Delaware corporation (“Borrower”), Agent, and Lenders are parties to that certain Amended and Restated Credit Agreement dated as of February 3, 2014 (as amended, restated, modified or supplemented from time to time, the “Credit Agreement”);

WHEREAS, to guarantee and secure payment and performance of the Obligations under the Credit Agreement, the Loan Parties and Agent entered into that certain Amended and Restated Guaranty and Security Agreement, dated as of February 3, 2014 (as amended, restated, supplemented or otherwise modified from time to time, the “Security Agreement”), pursuant to which each Guarantor guaranteed the Obligations and each Loan Party granted to Agent, for the benefit of the Lenders, a security interest in substantially all of each Loan Party’s assets;

WHEREAS, Borrower has sold all of the issued and outstanding shares of common stock (the “Shares”) of Heckmann Environmental Services, Inc., a Delaware corporation (“Heckmann”), and Heckmann is a holding company that owns all of the issued and outstanding shares of common stock of Thermo Fluids, Inc., a Delaware corporation (“Thermo Fluids”);

WHEREAS, in connection with such sale, Agent and the Lenders have (i) released Agent’s Lien on the Shares; (ii) released Agent’s Lien on the assets of Heckmann and Thermo Fluids; and (iii) released each of Heckmann and Thermo Fluids from its obligations under the Security Agreement and each other Loan Document;

WHEREAS, Agent and the Loan Parties have agreed to amend the Security Agreement in certain respects.

NOW THEREFORE, in consideration of the premises and mutual agreements herein contained, the parties hereto agree as follows:

1. Defined Terms. Unless otherwise defined herein, capitalized terms used herein and not otherwise defined shall have the meanings ascribed to such terms in the Security Agreement.

2. Amendment. In reliance upon the representations and warranties of the Grantors set forth in Section 6 below and subject to the satisfaction of the conditions to effectiveness set forth in Section 5 below:

(a) Section 1(a) of the Security Agreement is hereby amended by amending and restating the following defined term in its entirety as follows:

(lxxv) “Triggering Event” means, as of any date of determination, that (A) an Event of Default has occurred as of such date or (B) Excess Availability is less than the greater of (i) $24,375,000 and (ii) 12.5% of the Maximum Revolver Amount as of such date.

(b) Section 7(k)(ii) of the Security Agreement is hereby amended and restated as follows:

(ii) Each Grantor shall establish and maintain Controlled Account Agreements with Agent and the applicable Controlled Account Bank, in form and substance reasonably acceptable to Agent. Unless otherwise agreed to by Agent, each such Controlled Account Agreement shall provide, among other things, that (A) the Controlled Account Bank will comply with any instructions originated by Agent directing the disposition of the funds in such Controlled Account without further consent by the applicable Grantor, (B) the Controlled Account Bank waives, subordinates, or agrees not to exercise any rights of setoff or recoupment or any other claim against the applicable Controlled Account other than for payment of its service fees and other charges directly related to the administration of such Controlled Account and for returned checks or other items of payment, and (C) upon the instruction of Agent (an “Activation Instruction”), the Controlled Account Bank will forward by daily sweep all amounts in the applicable Controlled Account to the Agent’s Account. Agent agrees not to issue an Activation Instruction with respect to the Controlled Accounts unless a Triggering Event has occurred and is continuing at the time such Activation Instruction is issued. If a Triggering Event has occurred and is continuing, Agent may in its discretion issue an Activation Instruction, provided that if the Triggering Event exists as a result of Excess Availability being less than the greater of (i) $24,375,000 and (ii) 12.5% of the Maximum Revolver Amount, Agent shall issue such Activation Instruction. Agent agrees to use commercially reasonable efforts to rescind an Activation Instruction (the “Rescission”) if, after the occurrence of such Triggering Event, (x) ninety (90) consecutive days have passed during which Excess Availability has exceeded the greater of (i) $24,375,000 and (ii) 12.5% of the Maximum Revolver Amount and (y) no Event of Default has occurred and is continuing.

(c) Schedules 5, 6, 7, 8, 9, 10 and 11 to the Security Agreement are hereby replaced with Schedules 5, 6, 7, 8, 9, 10 and 11, respectively, attached hereto.

3. Effectiveness of Amendment; Continuing Effect. Except as expressly set forth in Section 2 above, nothing in this Amendment shall constitute a modification or alteration of the terms, conditions or covenants of the Security Agreement, the Credit Agreement or any other Loan Document, or a waiver of any other terms or provisions thereof, and the Security Agreement, the Credit Agreement and the other Loan Documents shall remain unchanged and shall continue in full force and effect, in each case as amended hereby. This Amendment is a Loan Document.

4. Reaffirmation and Confirmation; Covenant. Each Grantor hereby ratifies, affirms, acknowledges and agrees that the Security Agreement and the other Loan Documents to which it is a party represent the valid, enforceable and collectible obligations of such Grantor (except as may be limited by equitable principles or by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or limiting creditors’ rights generally), and further acknowledges that there are no existing claims, defenses, personal or otherwise, or rights of setoff whatsoever with respect to the Security Agreement or any other Loan Document. Each Grantor hereby agrees that this Amendment in no way acts as a release or relinquishment of the Liens and rights securing payments of the Obligations. The Liens and rights securing payment of the Obligations are hereby ratified and confirmed by each Grantor in all respects.

(a) after giving effect to this Amendment, all representations and warranties contained in the Loan Documents to which such Grantor is a party are true, correct and complete in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) on and as of the date of this Amendment, as though made on and as of such date (except to the extent that such representations and warranties relate solely to an earlier date, in which case such representations and warranties shall be true, correct and complete in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof) on and as of such earlier date);

(b) no Default or Event of Default has occurred and is continuing; and

(c) this Amendment and the Loan Documents, as amended hereby, constitute legal, valid and binding obligations of each Grantor and are enforceable against such Grantor in accordance with their respective terms, except as enforcement may be limited by equitable principles or by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or limiting creditors’ rights generally.

7. Miscellaneous.

(b) Choice of Law and Venue; Jury Trial Waiver; Reference Provision.
