WHEREAS, the Borrowers, Agent, and Lenders are parties to that certain Second Amended and Restated Credit Agreement dated as of June 28, 2016 (as amended, restated, supplemented or otherwise modified from time to time, the "Credit Agreement");

WHEREAS, an Event of Default under Section 8.14 of the Credit Agreement arising as a result of the occurrence of an "Event of Default" under Section 7(c) of the Term Loan Credit Agreement due to the Borrowers' failure to meet the minimum EBITDA required for the month ending October 31, 2016 (the "Minimum EBITDA EOD"); and

WHEREAS, Borrowers, Agent and Lenders have agreed to modify the Credit Agreement and waive the Minimum EBITDA EOD as provided herein, in each case subject to the terms and provisions hereof;

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

(a) The defined term "Borrowing Base" set forth in Schedule 1.1 to the Credit Agreement is hereby amended and restated in its entirety as follows:

"Borrowing Base" means, as of any date of determination, the lesser of (a) the ABL Borrowing Base and (b) the result of (i) the Term Loan Borrowing Base minus (ii) the outstanding principal balance of the Term Loan Debt (excluding the fee payable pursuant to that certain First Amendment Fee Letter dated August 22, 2016 among Borrowers, Term Loan Agent and Term Loan Lenders and the Fee payable pursuant to Section 4 of that certain Amended and Restated Fee Letter dated December 19, 2016 among Borrowers, Term Loan Agent and Term Loan Lenders);

3. Waiver. Subject to the satisfaction of the conditions set forth in Section 6 below and in reliance upon the representations and warranties set forth in Section 7 below, Agent and Lenders hereby waive the Minimum EBITDA EOD.

4. Continuing Effect.

5. Reaffirmation and Confirmation. Each Loan Party hereby ratifies, affirms, acknowledges and agrees that the Credit Agreement and the other Loan Documents represent the valid, enforceable and collectible obligations of such Loan Party, and further acknowledges that there are no existing claims, defenses, personal or otherwise, or rights of setoff whatsoever with respect to the Credit Agreement or any other Loan Document. Each Loan Party 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 the Loan Parties in all respects.

6. Conditions to Effectiveness of Amendment. This Amendment shall become effective as of the date first written above upon the satisfaction of the following conditions precedent:

(b) Agent shall have received an executed waiver and amendment to the Term Loan Credit Agreement, in form and substance acceptable to Agent;

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

(d) Counterparts. This Amendment may be executed in any number of counterparts, and by the parties hereto on the same or separate counterparts, and each such counterpart, when executed and delivered, shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Amendment. Delivery of an executed signature page of this Amendment by facsimile transmission or electronic photocopy (i.e. "pdf") shall be effective as delivery of a manually executed counterpart hereof.
