(c) The Issuer may change the percentages or the formulas set forth in either clause (a) or (b) above without the consent of any Noteholder so long as the Issuer has (i) received written confirmation from each Note Rating Agency that has rated any Outstanding Class A(2005-9) Notes that the change in either of such percentages or formulas, as applicable, will not result in a Ratings Effect with respect to any Outstanding Class A(2005-9) Notes and (ii) delivered to the Indenture Trustee and the Note Rating Agencies a Master Trust Tax Opinion and an Issuer Tax Opinion.

(a) For each Interest Payment Date, the amount of interest due with respect to the Class A(2005-9) Notes shall be an amount equal to the product of (i)(A) a fraction, the numerator of which is the actual number of days in the related

5

Interest Period and the denominator of which is 360, times (B) the Note Interest Rate in effect with respect to the related Interest Period, times, (ii) the Outstanding Dollar Principal Amount of the Class A(2005-9) Notes determined as of the close of business on the Interest Payment Date preceding the related Note Transfer Date for the Class A(2005-9) Notes; provided, however, that for the first Interest Payment Date, the amount of interest due with respect to the Class A(2005-9) Notes shall be an amount equal to the product of (x) the Outstanding Dollar Principal Amount of the Class A(2005-9) Notes on the Issuance Date, (y) 27 divided by 360 and (z) the Note Interest Rate in effect with respect to the Class A(2005-9) Notes determined on September 16, 2005.

Section 2.04 Calculation Agent; Determination of LIBOR.

(a) The Issuer hereby agrees that for so long as any Class A(2005-9) Notes are Outstanding, there shall at all times be an agent appointed to calculate LIBOR for each Interest Period (the “Calculation Agent”). The Issuer hereby initially appoints the Indenture Trustee as the Calculation Agent for purposes of determining LIBOR for each Interest Period. The Calculation Agent may be removed by the Issuer at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuer, or if the Calculation Agent fails to determine LIBOR for an Interest Period, the Issuer shall promptly appoint a replacement Calculation Agent that does not control or is not controlled by or under common control with the Issuer or its Affiliates. The Calculation Agent may not resign its duties, and the Issuer may not remove the Calculation Agent, without a successor having been duly appointed.

(b) On each LIBOR Determination Date, the Calculation Agent shall determine LIBOR on the basis of the rate for deposits in United States dollars for a one-month period which appears on Telerate Page 3750 or on such comparable system as is customarily used to quote LIBOR as of 11:00 a.m., London time, on such date. If such rate does not appear on Telerate Page 3750 or on a comparable system as is customarily used to quote LIBOR the rate for that LIBOR Determination Date shall be determined on the basis of the rates at which deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The Calculation Agent shall request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date shall be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the

6

Beneficiary, at approximately 11:00 a.m., New York City time, on that day for loans in United States dollars to leading European banks for a one-month period.

(c) The Note Interest Rate applicable to the then current and the immediately preceding Interest Periods may be obtained by telephoning the Indenture Trustee at its corporate trust office at ###-###-#### or such other telephone number as shall be designated by the Indenture Trustee for such purpose by prior written notice by the Indenture Trustee to each Noteholder from time to time.

(d) On each LIBOR Determination Date, the Calculation Agent shall send to the Indenture Trustee and the Beneficiary, by facsimile transmission, notification of LIBOR for the following Interest Period.

Section 2.05 Payments of Interest and Principal.

(a) Any installment of interest or principal payable on any Class A(2005-9) Note which is punctually paid or duly provided for by the Issuer and the Indenture Trustee on the applicable Interest Payment Date or Principal Payment Date shall be paid by the Paying Agent to the Person in whose name such Class A(2005-9) Note (or one or more Predecessor Notes) is registered on the Record Date, by wire transfer of immediately available funds to such Person’s account as has been designated by written instructions received by the Paying Agent from such Person not later than the close of business on the third Business Day preceding the date of payment or, if no such account has been so designated, by check mailed first-class, postage prepaid to such Person’s address as it appears on the Note Register on such Record Date, except that with respect to Notes registered on the Record Date in the name of the nominee of Cede & Co., payment shall be made by wire transfer in immediately available funds to the account designated by such nominee.

Section 2.08 Supplemental Indenture. The Issuer may enter into a supplemental indenture with respect to the Class A(2005-9) Notes as provided in Section 9.01 of the Indenture; provided, however, that any supplemental indenture which provides for an additional or alternative form of credit enhancement for the Class A(2005-9) Notes shall, in addition to the requirements set forth in Section 9.01 of the Indenture, require confirmation from the Note Rating Agencies that have rated any Outstanding Notes of the CHASEseries that such change in credit enhancement will not result in a Ratings Effect with respect to any Outstanding Notes of the CHASEseries.

Section 2.09 Appointment of co-Paying Agent and co-Transfer Agent. BDL is appointed as co-paying agent and as co-transfer agent in Luxembourg with respect to the Class A(2005-9) Notes for so long as the Class A(2005-9) Notes are listed on the Luxembourg Stock Exchange.
