Terms used herein and not otherwise defined herein shall have the meanings assigned in the RPA.

The parties to the RPA enter into this Amendment to provide for certain modifications to the terms and provisions of the RPA as more particularly set forth hereinbelow.

NOW THEREFORE, in consideration of the premises herein contained, and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto hereby agree as follows:

1. Amendments to the RPA. Subject to the satisfaction of the conditions precedent set forth in Section 2 below, the RPA is hereby amended as set forth below:

1.1. Exhibit I to the RPA is amended to delete in its entirety the definition therein of “CP Rate” and to substitute the following definition therefor:

“CP Rate” means, for any day, for any Purchaser Interests funded by a Conduit through the issuance of Commercial Paper, the Daily/30 Day LIBOR Rate in respect of such day. “Daily/30 Day LIBOR Rate” shall mean, for any day, a

rate per annum equal to the thirty (30) day London-Interbank Offered Rate appearing on the Bloomberg BBAM (British Bankers Association) Page (or on any successor or substitute page of such service, providing rate quotations comparable to those currently provided on such page of such service, as determined by the Administrative Agent from time to time in accordance with its customary practices for purposes of providing quotations of interest rates applicable to U.S. Dollar deposits in the London interbank market) at approximately 11:00 a.m. (London time) on such day or, if such day is not a Business Day in London, the immediately preceding Business Day in London. In the event that such rate is not available on any day at such time for any reason, then the “Daily/30 Day LIBOR Rate” for such day shall be the rate at which thirty (30) day U.S. Dollar deposits of $5,000,000 are offered by the principal London office of the Administrative Agent in immediately available funds in the London interbank market at approximately 11:00 a.m. (London time) on such day; and if the Administrative Agent is for any reason unable to determine the Daily/30 Day LIBOR Rate in the foregoing manner or has determined in good faith that the Daily/ 30 Day LIBOR Rate determined in such manner does not accurately reflect the cost of acquiring, funding or maintaining a Purchaser Interest, the Daily/30 Day LIBOR Rate for such day shall be the Alternate Base Rate.

1.2.    Exhibit I to the RPA is amended to delete in its entirety the definition therein of “Liquidity Termination Date” and to substitute the following definition therefor:

“Liquidity Termination Date” means November 16, 2012.

1.3.    Schedule A to the RPA is replaced in its entirety with the Schedule A attached hereto.
