     WHEREAS, the Borrower has requested that the Lenders amend the Credit Agreement to allow certain payments relating to the Tax Receivable Agreement, and the Lenders are willing to amend the Credit Agreement on the terms, and subject to the conditions, set forth herein;

     NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

Section 1. Amendments. The Credit Agreement is hereby amended as follows:

     (a) Section 1.01 of the Credit Agreement is hereby amended by adding the following defined term in appropriate alphabetical order:

     “Permitted Tax Receivable Agreement Prepayment” means any prepayment made under the Tax Receivable Agreement; provided, that (a) such prepayment is made at a discount to the present value of all or a portion of the Borrower’s remaining obligations under the Tax Receivable Agreement, calculated in a manner reasonably satisfactory to the Administrative Agent, (b) such prepayment satisfies in full all or the applicable portion of the Borrower’s remaining obligations under the Tax Receivable Agreement, other than contingent indemnification obligations under the Tax Receivable Agreement for which no claim has been asserted, (c) such prepayment is made on or before September 30, 2009, (d) the terms and conditions of such prepayment are otherwise reasonably satisfactory to the Administrative Agent, and (e) both before and after giving effect to such prepayment, no Event of Default shall have occurred and be continuing, including, on a Pro Forma Basis, under Section 7.11.

     (b) Section 2.09(b) of the Credit Agreement is hereby amended by adding the following clause (iii) after clause (ii) thereof:

     “(iii) The Borrower shall pay to each Lender executing the Amendment to Credit Agreement, dated as of June 26, 2009, a fee equal to 0.25% of such Lender’s Commitment on such date. A portion of such fee equal to 0.05% of each Lender’s Commitment shall be due and

payable on the effective date of such amendment, and the balance of such fee shall be payable on the first date on which the Borrower makes a Permitted Tax Receivable Agreement Prepayment. Such fees shall be fully earned when due and shall not be refundable for any reason whatsoever.”

     (c) Section 7.14 of the Credit Agreement is hereby amended (i) by inserting the following text immediately after the word “Lenders” in clause (i) thereof:

“(and for the avoidance of doubt, agreements effecting Permitted Tax Receivable Agreement Prepayments that have been approved by the Administrative Agent, acting reasonably, are not materially disadvantageous to the Lenders)”

and (ii) by inserting the following text immediately after the word “Agreement” at the end of clause (ii) thereof:

     “, other than Permitted Tax Receivable Agreement Prepayments”

Section 2. Representations and Warranties. The Borrower represents and warrants as follows:

     (a) Before and after giving effect to this Amendment, all representations and warranties of the Loan Parties set forth in the Loan Documents are true and correct in all material respects on and as of the date hereof as if made on such date (except to the extent that such representations and warranties expressly relate to an earlier date).

     (b) After giving effect to this Amendment, the Loan Parties are in compliance with all of the terms and provisions set forth in the Loan Documents on their part to be observed or performed thereunder.

     (c) Both before and after giving effect to this Amendment, no Default or Event of Default shall have occurred and be continuing.

     (d) Both before and after Borrower makes any Permitted Tax Receivable Agreement Prepayment, no Default or Event of Default shall have occurred and be continuing.
