NOW, THEREFORE, the parties hereto, in consideration of their mutual covenants hereinafter set forth and intending to be legally bound hereby, agree as follows:

SECTION 1.01    Capitalized Terms. Capitalized terms used in this Amendment and not otherwise defined herein shall have the meanings ascribed thereto in the RSA or the RPAA, as applicable.

SECTION 2.01    Amendment. Section 5.05 of the RSA is hereby deleted in its entirety and is hereby replaced with the following new Section 5.05 and Section 5.06:

Section 5.05    Credit Agreement Responsibility Transfers.

(a)Subject to the prohibition set forth in Section 5.05(c) below, in the event that that an Asset Base Deficiency under the Receivables Purchase and Administration Agreement would occur as a result of a Transferred Receivable becoming a Change of Responsibility Receivable thereunder and the Purchaser, pursuant to Section 2.15(d)(i) of the Receivables Purchase and Administration Agreement, replaces or repurchases Change of Responsibility Receivables and other Purchased Assets, such Receivables and other Purchased Assets shall immediately thereafter be replaced or repurchased, as applicable, automatically, and without further action by the Purchaser or Finco, on the same date, for the same amount and on the same terms of the corresponding replacement or repurchase by the Purchaser, as applicable, to take place under Section 2.15(d) of the Receivables Purchase and Administration Agreement so that the Purchaser can fulfill its obligations thereunder.

(b)Subject to the prohibition set forth in Section 5.05(c) below, to the extent that an Asset Base Deficiency under the Receivables Purchase and Administration Agreement would not occur as a result of a Transferred Receivable becoming a Change of Responsibility Receivable thereunder, Finco shall have the right to direct the Purchaser to replace or repurchase such Change of Responsibility Receivable and other Purchased Assets pursuant to the terms set forth in Section 2.15(d)(ii) of the Receivables Purchase and Administration Agreement. In the event that Finco has directed the Purchaser, the Purchaser shall abide by such direction and replace or repurchase such Change of Responsibility Receivables and other Purchased Assets pursuant to the terms set forth in Section 2.15(d)(ii) of the Receivables Purchase and Administration Agreement, and such Receivables and other Purchased Assets shall immediately thereafter be replaced or repurchased, as applicable, automatically, and without further action by the Purchaser or Finco, on the same date, for the same amount and on the same terms of the corresponding replacement or repurchase by the Purchaser, as applicable, to take place under Section 2.15(d) of the Receivables Purchase and Administration Agreement.

(c)For purposes of this Section 5.05, Finco shall be prohibited from repurchasing or replacing Change of Responsibility Receivables pursuant to the terms hereof if at the time of such repurchase or replacement, as applicable, and after giving effect thereto, the aggregate Receivables Balances immediately prior to the repurchase or replacement, as applicable, for all Change of Responsibility Receivables repurchased or replaced by Finco during the past twelve (12) months would exceed 10.00% of the Aggregate Receivables Balance.  In the event that such prohibition applies, Finco will no longer consent to (or permit any of its Affiliates to consent to) any Receivable that has been transferred by Finco to the Purchaser pursuant to the terms hereof from becoming a Change of Responsibility Receivable.

(d)All of the retransfers of Receivables contemplated by this Section 5.05 shall occur without recourse to, and without warranty of any kind deemed to have been made by, the Purchaser, and all representations and warranties are hereby

expressly disclaimed. Upon the payment of the amounts or the transfer of the Receivables described in this Section 5.05, the Purchaser shall assign to Finco all of the Purchaser’s right, title and interest in the related Change in Responsibility Receivable and other Purchased Assets, in each case received and released from the Purchaser in accordance with the Receivables Purchase and Administration Agreement, without recourse, representation or warranty.
