R E C I T A L S

A. The Borrower, the MLP, the Administrative Agent and the Lenders are parties to that certain Amended and Restated 5-Year Revolving Credit Agreement dated as of October 29, 2014 (as amended, modified or supplemented prior to the date hereof, the “Credit Agreement”), pursuant to which the Lenders have made certain extensions of credit available to the Borrower.

B. The Subsidiary Guarantor is a party to that certain Amended and Restated Subsidiary Guaranty Agreement dated as of October 29, 2014 made by each of the Guarantors (as defined therein) in favor of the Administrative Agent (the “Subsidiary Guaranty”).

C. The Borrower has requested and the Lenders have agreed to amend certain provisions of the Credit Agreement.

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

Section 1. Defined Terms. Each capitalized term used herein but not otherwise defined herein has the meaning given such term in the Credit Agreement. Unless otherwise indicated, all references to Sections in this Ninth Amendment refer to Sections of the Credit Agreement.

Section 2. Amendments to the Credit Agreement.

2.1 Section 1.01 is hereby amended as follows:

(a) The definition of “Consolidated EBITDA” is hereby amended by adding the following sentence at the end thereof: “Notwithstanding anything to the contrary set forth in this definition, all Non-Controlling Interest Income shall be excluded from Consolidated EBITDA (and none of the foregoing add-backs to Consolidated EBITDA shall be permitted in respect of any Non-Controlling Interest Income).”.

(b) The definition of “Consolidated Debt Coverage Ratio” is hereby amended by replacing the reference to “$200,000,000” therein with “$275,000,000”.

“Available Cash Netting Amount” means, as of the last day of any Rolling Period, the aggregate amount of Unrestricted Cash as of such date that is held in accounts of the Borrower maintained with one or more Lenders in excess of $25,000,000, but only to the extent that the Borrower, on such date, specifically intends to use such excess Unrestricted Cash to Redeem, during the period from and including the last day of such Rolling Period to but excluding the date that is 365 days thereafter (such period, when used in reference to Specified Redemption Indebtedness applicable to any Available Cash Netting Amount, the “Specified Redemption Period”), the principal amount of Indebtedness of the MLP or any of its Restricted Subsidiaries outstanding on the last day of such Rolling Period, as such Indebtedness (and the principal amount thereof) is specified in the compliance certificate delivered to the Administrative Agent and the Lenders for such Rolling Period pursuant to Section 5.01(c) (such Indebtedness applicable to any Available Cash Netting Amount, the “Specified Redemption Indebtedness”).

“Consolidated Interest Expense” means, for any Rolling Period, the sum (determined without duplication) of (a) the consolidated interest expense of the MLP and its Restricted Subsidiaries for such Rolling Period, whether paid or accrued, determined in accordance with GAAP, and (b) all cash dividend payments or other cash distributions in respect of any series of preferred equity of the MLP or its Restricted Subsidiaries made during such Rolling Period. Consolidated Interest Expense for any Rolling Period shall be calculated by the Borrower in good faith on a pro forma basis to give effect to any Indebtedness permanently repaid or extinguished, or any Indebtedness assumed or incurred, in each case at any time during such Rolling Period in connection with acquisitions, Investments (other than Joint Venture Interests), sales or other transfers of property (including any contributions of assets to joint ventures not otherwise prohibited hereby, but excluding any dispositions in the ordinary course of business) by the MLP and its Restricted Subsidiaries during such Rolling Period, in each case as if such repayment, extinguishment, assumption or incurrence had been effected on the first day of such Rolling Period; provided that any such pro forma adjustment with respect to a repayment or extinguishment of Indebtedness shall be permitted only if (x) the aggregate amount of Indebtedness of the MLP and its Restricted Subsidiaries on the last day of the fiscal quarter in which such repayment or extinguishment of Indebtedness occurred is less than or equal to (y) the aggregate amount of Indebtedness of the MLP and its Restricted Subsidiaries on the last day of the fiscal quarter immediately preceding the quarter in which such repayment or extinguishment of Indebtedness occurred. For purposes of any such pro forma adjustment with respect to any Indebtedness assumed or incurred that bears a floating rate of interest, the interest expense for the portion of the Rolling Period prior to the date on which such Indebtedness was assumed or incurred shall be calculated using the interest rate in effect on the last day of the Rolling Period.

“Consolidated Operating Income” means, as to the MLP and its Restricted Subsidiaries on a consolidated basis for each Rolling Period, the amount equal to gross margin minus operating expenses, general and administrative expenses, depreciation and amortization, taxes (other than income taxes) and Non-Controlling Interest Income, in each case for such period.

(d) Each of the following definitions is hereby added where alphabetically appropriate:

“Non-Controlling Interest” means any non-controlling equity interests or minority equity interests of unaffiliated third parties in any non-wholly owned Subsidiary.

“Non-Controlling Interest Income” means the amount of income attributable to any Non-Controlling Interest.

“Specified Redemption Indebtedness” has the meaning assigned to such term in the definition of “Available Cash Netting Amount”.

“Specified Redemption Period” has the meaning assigned to such term in the definition of “Available Cash Netting Amount”.

2.2 Amendment to Section 5.01(a)-(c). Sections 5.01(a), (b) and (c) are hereby amended and restated in their entirety to read as follows:
