Ladies and Gentlemen:

Nuverra Environmental Solutions, Inc., a Delaware corporation (the “Company”), has advised each of the undersigned (collectively, the “Backstop Parties” and individually each a “Backstop Party”) that the Company intends to initiate a rights offering (the “Rights Offering”) to all of its common shareholders (“Common Shareholders”) as of the record date (the “Record Date”) to be set by the Board of Directors of the Company (the “Board of Directors”) pursuant to which the Company will distribute to such Common Stockholders on a pro rata basis at no charge purchase rights (each a “Basic Subscription Right”) to the holders of common stock (“Common Stock”) as of the Record Date. Each Common Shareholder that exercises its Basic Subscription Rights in full may subscribe for additional shares of Common Stock, to the extent available, on the terms set forth in the attached Exhibit A (the “Term Sheet”) (the “Over-Subscription Right” and, together with the Basic Subscription Rights, the “Subscription Rights”). The Company is proposing to offer and sell, pursuant to the Rights Offering, in the aggregate a minimum number of shares of Common Stock resulting in gross cash proceeds to the Company of at least $32,500,000 (the “Minimum Rights Offering Proceeds Amount”), on the terms described in the Term Sheet. This letter agreement (including the Term Sheet, this “Letter Agreement”) sets forth the terms and conditions under which the Backstop Parties have agreed to provide the Backstop Commitments referenced below. Capitalized terms used herein but not defined herein have the meaning given to them in the Term Sheet.

The term “Unsubscribed Shares” shall mean such number of shares of Common Stock equal to the excess, if any, of (i) the aggregate number of shares of Common Stock that may be purchased pursuant to all Subscription Rights issued by the Company in connection with the Rights Offering, over (ii) the aggregate number of shares of Common Stock that are purchased by participating Common Shareholders in the Rights Offering pursuant to Subscription Rights.

Each of the foregoing Basic Commitments and Backstop Commitments is further subject to (i) the Company filing with the SEC a registration statement containing a prospectus relating to the Rights Offering, in form and substance reasonably acceptable to the Backstop Parties (the “Rights Offering Registration Statement”), not later than the date that is twenty (20) calendar days following the date of execution of this Letter Agreement, (ii) the Company using its reasonable best efforts to cause the Rights Offering Registration Statement to become effective as promptly as practicable, and in no event later than the date that is twenty (20) calendar days prior to the Maturity Date of the Bridge Facility (as defined below), (iii) the Company entering into the Bridge Facility on terms satisfactory to the Backstop Parties in their sole discretion; (iv) no (a) default or event of default relating to payment obligations, bankruptcy or insolvency having occurred under the First Lien Credit Agreement dated as of August 7, 2017 or (b) default or event of default having occurred under the subordinated Bridge Term Loan Credit Agreement dated as of October 5, 2018 (as amended, restated, supplemented or otherwise modified from time to time) by and among the Company, as borrower, the lenders from time to time parties thereto, and Wilmington Savings Fund Society, FSB, as administrative agent (the “Bridge Facility”) and (v) the completion of the acquisition by the Company or its applicable subsidiaries of all of the membership interests of each of Clearwater Three, LLC, an Ohio limited liability company, Clearwater Five, LLC, an Ohio limited liability company and Clearwater Solutions, LLC, an Ohio limited liability company not later than October 12, 2018 (the “Clearwater Acquisition”).

2.    This Letter Agreement, including the undersigned’s obligations to fund the Backstop Commitment, terminates upon the earliest to occur of (a) the receipt by the Company of gross cash proceeds from the Rights Offering from participating Common Shareholders (including the Backstop Parties, pursuant to their exercise of their Subscription Rights received in the Rights Offering) in an aggregate amount of at least $32,500,000, (b) the date on which the Company provides written notice to the Backstop Parties that it is terminating this Letter Agreement, (c) the date on which the Backstop Parties have provided the Company with cash in the amount of the full amount of the Backstop Commitments on the terms set forth in this Letter Agreement, or (d) January 31, 2019.

6.    Notwithstanding anything to the contrary contained herein, the Company, in accepting the Backstop Commitments hereunder, agrees and acknowledges the liability and obligations of the Backstop Parties hereunder shall not exceed their respective Maximum Backstop Commitments. The Backstop Parties’ commitment, if any, to contribute or otherwise fund to the Company an amount determined pursuant to this Letter Agreement up to, but in no case exceeding, their respective Maximum Backstop Commitments shall be the sole and exclusive remedy of the Company against the Backstop Parties and their respective affiliates in respect of this Letter Agreement, and the Company, on behalf of itself and its affiliates, hereby waives all other rights and remedies it may have against the Backstop Parties and their respective affiliates (other than the Company), whether sounding in contract or tort, or whether at law or in equity, or otherwise, relating to this Letter Agreement.

In the case of an investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Company, its subsidiaries, its equityholders or creditors or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Rights Offering or other transactions contemplated by this Letter Agreement is consummated.

Notwithstanding any other provision of this Commitment Letter, no Indemnified Party shall be liable for any damages arising from the use by the Company of information or other materials relating to the Rights Offering communications by the Company through electronic telecommunications or other information transmission systems, other than for direct or actual damages resulting from the gross negligence or willful misconduct of such Indemnified Party as determined by a final and nonappealable judgment of a court of competent jurisdiction
