Section 2.Amendments to Credit Agreement.

(a)    In reliance on the representations, warranties, covenants and agreements contained in this Amendment, but subject to the satisfaction of each condition precedent set forth in Section 5 hereof, the Credit Agreement shall be amended effective as of the Ninth Amendment Effective Date (i) to delete the red or green stricken text (indicated textually in the same manner as the following examples: stricken text and stricken text) and (ii) to add the blue or green text (indicated textually in the same manner as the following examples: double underline text and double underline text), in each case, as set forth in the marked copy of the Credit Agreement attached as Annex I hereto and made a part hereof for all purposes.

Upon the Ninth Amendment Effective Date, (i) each Lender who holds Loans in an aggregate amount less than its respective Pro Rata Share (after giving effect to this Amendment) of all Committed Loans shall advance new Committed Loans which shall be disbursed to the Administrative Agent and used to repay (x) the Committed Loans outstanding to each Lender (other than Exiting Lenders) who holds Committed Loans in an aggregate amount greater than its respective Pro Rata Share of all Committed Loans and (y) the Committed Loans outstanding immediately prior to the Ninth Amendment Effective Date held by each Exiting Lender, (ii) each Lender’s (including each Exiting Lender’s) participation in the L/C Obligations shall be automatically adjusted (x) with respect to each Lender other than an Exiting Lender, to equal its Pro Rata Share (after giving effect to this Amendment) and (y) with respect to each Exiting Lender, to zero, and (iii) such other adjustments shall be made as the Administrative Agent shall specify so that the amount of each Lender’s respective Outstanding Amount equals (x) with respect to each Lender other than an Exiting Lender, its Pro Rata Share (after giving effect to this Amendment) of the Outstanding Amount of all Committed Loans and L/C Obligations and (y) with respect to each Exiting Lender, zero.

Section 3.Exiting Lenders. Subject to the occurrence of the Ninth Amendment Effective Date, each of the Exiting Lenders hereby (a) consents to this Amendment as required under Section 10.01 of the Credit Agreement solely with respect to and to the extent such consent is necessary to effect the provisions of Section 2(b) above and this Section 3 and (b) acknowledges and agrees to Section 2(b) of this Amendment.

The Existing Lenders and the New Lender hereby waive any requirement of the Credit Agreement (including Section 2.03(e) of the Credit Agreement) that requires payments to Lenders to be made on a pro rata basis solely to the extent necessary to permit the payment to the Exiting Lenders of the amounts required by Section 2(b) and Section 5(h) of this Amendment. For the avoidance of doubt, in addition to the payments of principal, reallocations, adjustments and other actions contemplated under Section 2(b) of this Amendment and this Section 3, the Borrower shall pay (or cause to be paid) all interest, fees and other charges owed to the Exiting Lenders under the Loan Documents as of the Ninth Amendment Effective Date, including without limitation in connection with the payment in full of the Committed Loans held by, and the termination in full of all Commitments of, such Exiting Lenders contemplated hereby.
