WHEREAS, this Amendment No. 5 shall constitute a Loan Document, these Recitals shall be construed as part of this Amendment No. 5 and capitalized terms used but not otherwise defined in this Amendment No. 5 shall have the meanings ascribed to them in the Credit Agreement.

NOW, THEREFORE, for and in consideration of the premises and mutual agreements herein contained and for the purposes of setting forth the terms and conditions of this Amendment No. 5, the parties, intending to be bound, hereby agree as follows:

SECTION 1. Amendments. Subject to the satisfaction of the conditions set forth in Section 3 of this Amendment No. 5, and in reliance on the representations and warranties set forth in Section 5 of this Amendment No. 5, the Loan Parties, the Administrative Agent and the Required Lenders hereby agree to amend the Credit Agreement as of the Amendment No. 5 Effective Date as follows:

“Notwithstanding the foregoing, the LC Issuer may issue one or more Letters of Credit in U.S. Dollars with an expiration date which is later than the date otherwise permitted by this Section 1.3 but not later than the third anniversary of the scheduled Revolving Credit Termination Date (“Exception Letter of Credit”); provided that (a) the aggregate outstanding amount of the L/C Obligations with respect to all Exception Letters of Credit shall not at any time exceed Two Million Five Hundred Thousand Dollars ($2,500,000) and (b) Borrowers shall Cash Collateralize all Exception Letters of Credit on or prior to the Revolving Credit Termination Date (or such earlier date as may be requested by the LC Issuer or the Administrative Agent during the existence of an Event of Default).”

(b) Section 5.1 (Definitions – Amended and Restated). Section 5.1 of the Credit Agreement is hereby amended by amending and restating the following definitions:

“Alternative Currency Sublimit”: $0.00.

“Applicable Margin” means, with respect to Loans, Reimbursement Obligations, and the commitment fees and letter of credit fees payable under Section 2.1 hereof, until the Pricing Date with respect to the last day of Parent’s fiscal quarter March 2018, the rates per annum shown opposite Level II below, and thereafter from one Pricing Date to the next the Applicable Margin means the rates per annum determined in accordance with the following schedule:

For purposes hereof, the term “Pricing Date” means, for any measurement period of the Borrowers ending on or after the last day of Parent’s fiscal quarter March 2018, the date on which the Administrative Agent is in receipt of the Borrowers’ most recent financial statements (and, in the case of the year-end financial statements, audit report) for the fiscal quarter then ended, pursuant to Section 8.5 hereof. The Applicable Margin shall be established based on the Total Funded Debt/EBITDA Ratio for the most recently completed fiscal quarter and the Applicable Margin established on a Pricing Date shall remain in effect until the next Pricing Date. If the Borrowers have not delivered their financial statements by the date such financial statements (and, in the case of the year-end financial statements, audit report) are required to be delivered under Section 8.5 hereof, until such financial statements and audit report are delivered, the Applicable Margin shall be the highest Applicable Margin (i.e., Level II shall apply). If the Borrowers subsequently deliver such financial statements before the next Pricing Date, the Applicable Margin established by such late delivered financial statements shall take effect from the date of delivery until the next Pricing Date. In all other circumstances, the Applicable Margin established by such financial statements shall be in effect from the Pricing Date that occurs immediately after the end of the fiscal quarter covered by such financial statements until the next Pricing Date. Each determination of the Applicable Margin made by the Administrative Agent in accordance with the foregoing shall be conclusive and binding on the Borrowers and the Lenders if reasonably determined.
