Attention: D. West Griffin,     Executive Vice President and Chief Financial Officer

Ladies and Gentlemen:

Borrower Agent has advised Agent and Lenders that Obligors will not be able to deliver the financial statements for the Fiscal Quarter ended September 30, 2017 (the "9/30/17 Financial Statements") within the number of days after such Fiscal Quarter end required by Section 9.1.1(b) of the Credit Agreement. In accordance with Section 13.1.1 of the Credit Agreement, Borrower Agent has requested that Required Lenders consent to Obligors' departure from the requirements of Section 9.1.1(b) of the Credit Agreement with respect to the delivery of the 9/30/17 Financial Statements.

Each of the undersigned Lenders consents to Obligors' departure from Section 9.1.1(b) of the Credit Agreement with respect to the timely delivery of the 9/30/17 Financial Statements, which consent is subject to Obligors' compliance with the agreements set forth in this letter (this "Consent Letter") below.

To induce Agent and Required Lenders to agree to the terms of this Consent Letter, Borrowers (by their execution below) hereby agree as follows:

1.Obligors will deliver to Agent the 9/30/17 Financial Statements meeting the requirements of Section 9.1.1(b) of the Credit Agreement on or before December 31, 2017. The failure to deliver such financial statements by such date shall constitute an Event of Default.

2.The agreements of Lenders set forth herein shall not be deemed a consent to the departure from or a waiver of: (a) Section 9.1.1(b) of the Credit Agreement for any purpose other than as specifically set forth herein with respect to the 9/30/17 Financial Statements, (b) any other covenant or condition in any Credit Document, or (c) any Default that may otherwise arise or that may be reflected in the financial statements delivered pursuant to paragraph 1 above. The failure to comply fully with Section 9.1.1(b) of the Credit Agreement with respect to any other date, year, time or other matter shall constitute an Event of Default.

3.Except as specifically set forth herein, all terms and provisions of the Credit Documents, all rights of Agent and Lenders thereunder and all obligations of Obligors thereunder shall remain in full force and effect and are ratified and confirmed in all respects.

4.The Credit Agreement and the other Credit Documents shall continue to be legal, valid, binding and enforceable in accordance with their respective terms.

Each Borrower also represents and warrants to Agent and each Lender that the following statements are true, correct and complete: (a) no Default has occurred and is continuing and (b) the representations and warranties set forth in the Credit Documents are true and correct on and as of the date hereof with the same effect as though made on and as of such date (except for representations and warranties that expressly relate only to an earlier date, which shall be true and correct on such date).

This Consent Letter embodies the final, entire agreement among the parties hereto and supersedes any and all prior commitments, agreements, representations and understandings, whether written or oral, relating to the subject matter hereof, and may not be contradicted or varied by evidence of prior, contemporaneous or subsequent oral agreements or discussions of the parties hereto. This Consent Letter is to be governed by and construed in accordance with the applicable law pertaining in the State of New York, other than those conflict of law provisions that would defer to the substantive laws of another jurisdiction. This governing law election has been made by the parties in reliance (at least in part) on Section 5-1401 of the General Obligations Law of the State of New York, as amended (as and to the extent applicable), and other applicable law. This Consent Letter may be executed in one or more counterparts and on telecopied or other electronically reproduced counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same agreement.

The consent contemplated by this Consent Letter may be granted with the agreement of Required Lenders, which term is defined in the Credit Agreement to mean Lenders having more than fifty percent (50%) of the Revolving Commitments (such percentage applicable to a Lender, herein such Lender's "Required Lender Percentage"). For purposes of determining the effectiveness of this Consent Letter, each Lender's Required Lender Percentage is set forth on Schedule 1 attached hereto.

Very truly yours,
