Item 1.01. Entry into a Material Definitive Agreement

On March 18, 2014, Nuverra Environmental Solutions, Inc., a Delaware corporation (the “Company” or “Borrower”), entered into a Joinder and First Amendment to Amended and Restated Credit Agreement (the “Joinder and First Amendment”) by and among Wells Fargo Bank, National Association, as agent (“Agent”) for the Lenders (as named in the Existing Credit Agreement defined below) (the “Lenders”), the Lenders a party to the Joinder and First Amendment, the Borrower, Capital One Business Credit Corporation (“Capital One”) and CIT Finance LLC (“CIT”; and together with Capital One, collectively the “New Lenders” and each individually a “New Lender”). This agreement amends the Company’s existing Amended and Restated Credit Agreement, dated as of February 3, 2014, by and among the Borrower, the Agent, and certain lenders named therein (as amended, the “Existing Credit Agreement”).

The Joinder and First Amendment increases the maximum revolver availability from $200 million to $245 million and joins each New Lender as a Lender under the Existing Credit Agreement. This Joinder and First Amendment also expands the accordion feature in the Existing Credit Agreement, by increasing additional availability to up to $50 million, subject to the satisfaction of the same terms and conditions contained in the Existing Credit Agreement and related documentation.

The foregoing description of the Existing Credit Agreement and the Joinder and First Amendment is only a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the Joinder and First Amendment, a copy of which is attached hereto as Exhibit 10.1, and the Existing Credit Agreement, a copy of which is attached as Exhibit 10.1 to the Company’s Current Report on Form 8-K dated February 3, 2014.

Item 7.01. Regulation FD Disclosure

On March 19, 2014, the Company issued a press release announcing that it had entered into the Joinder and First Amendment described above. A copy of the press release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference.
