WHEREAS, the Borrower has requested a waiver of certain Events of Default that have occurred or are anticipated to occur under the Credit Agreement, and the Lenders have agreed to the requested waiver on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.                                       Defined Terms .  Capitalized terms defined in the Credit Agreement and used herein without other definition shall have the meanings ascribed to such terms in the Credit Agreement.

2.                                       Estoppel, Acknowledgement and Reaffirmation .  Each of the Loan Parties acknowledges and confirms that as of the date hereof (a) the aggregate outstanding principal amount of the Term A Loans is $199,687,500 and (b) the Total Revolving Usage is $136,300,000, each of which amounts constitutes a valid and subsisting obligation of the Loan Parties to the Lenders that is not subject to any credits, offsets, defenses, claims, counterclaims or adjustments of any kind (it being understood that the undrawn portion of the Stated Amount of outstanding Letters of Credit included in the Total Revolving Usage, if any, constitutes a contingent obligation for so long as the Loan Parties are not required to cash collateralize such obligation in accordance with the Credit Agreement).  Each of the Loan Parties hereby acknowledges its obligations under the respective Loan Documents to which it is a party, reaffirms that each of the Liens created and granted in or pursuant to the Collateral Documents is valid and subsisting and agrees that this Amendment shall in no manner impair or otherwise adversely affect such obligations or Liens, except as explicitly set forth herein.

3.2                                Anticipated Financial Information Events of Default .

(c)                                The execution and delivery by the Borrower of that certain Fifth Supplemental Indenture dated on or about December 11, 2015 did not violate the covenant set forth in Section 8.16 of the Credit Agreement.
