 (a) The Issuing Entity hereby agrees that for so long as any Class A(2007-12) Notes are Outstanding, there shall at all times be an agent appointed to
calculate LIBOR for each Interest Period (the “Calculation Agent”). The Issuing Entity 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 Issuing Entity at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuing Entity, or if the Calculation Agent fails to determine LIBOR for an Interest Period, the Issuing

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 Reuters Screen LIBO Page 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 Reuters Screen LIBO Page 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

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 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 (612) 667-8058 or such other telephone

The right of the Class A(2007-12) Noteholders to receive payments from the Issuing Entity will terminate on the first Business Day following the Class A(2007-12) Termination Date. 
 Section 2.06 Form of Delivery of Class A(2007-12) Notes; Depository; Denominations. 
 (a) The Class A(2007-12) Notes shall be delivered in the form of a global Registered Note as provided in Sections 2.02 and 3.01(i) of the Indenture,

 Section 2.08 Supplemental Indenture The Issuing Entity may enter into a supplemental indenture with respect to the Class A(2007-12) 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(2007-12) 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(2007-12) Notes for so long as the Class A(2007-12) Notes are listed on the Luxembourg Stock Exchange. Any
