SECTION 1.Amendments to the Series 2017-VF1 Indenture Supplement.

(a)Section 2 of the Series 2017-VF1 Indenture Supplement is hereby amended by adding the following definitions in proper alphabetical order:

“Adjusted Daily Simple SOFR” means an interest rate per annum equal to (i) the Daily Simple SOFR, plus (ii) the applicable Benchmark Adjustment.  The Calculation Agent shall not be responsible for calculating the Adjusted Daily Simple SOFR.

“Daily Simple SOFR” means, for any day, SOFR, with conventions (including, without limitation, a lookback) established by the Administrative Agent in its sole and good faith discretion; provided that, if the Administrative Agent determines that any such convention is not administratively, operationally, or technically feasible for the Administrative Agent, then the Administrative Agent may establish another convention in its sole and good faith discretion.

“Benchmark Adjustment” means, for any day, the spread adjustment for such Interest Accrual Period that has been selected or recommended by the Relevant Governmental Body for the tenor of 1 month. For the avoidance of doubt, the “Benchmark Adjustment” means, for any day, the value as reported on the display designated as “YUS0001M” on Bloomberg, or such other display as may replace “YUS0001M.”

“Benchmark Administration Changes” means, with respect to the Benchmark (including any Benchmark Replacement Rate), any technical, administrative or operational changes (including without limitation changes to the timing and frequency of determining rates and making payments of interest, length of lookback periods, and other administrative matters as may be appropriate, in the sole and good faith discretion of Administrative Agent, to reflect the adoption and implementation of such Benchmark and to permit the administration thereof by Administrative Agent in a manner substantially consistent with market practice (or, if Administrative Agent determines that adoption of any portion of such market practice is not administratively feasible or that no market practice for the administration of such Benchmark exists, in such other manner of administration as Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement).

“Benchmark Replacement Rate” means with respect to any Benchmark Transition Event, the sum of: (i) the alternate benchmark rate that has been selected in the sole and good faith discretion of Administrative Agent, giving due consideration to (A) any selection or recommendation of a replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (B) any evolving or then-prevailing market convention for

3

determining a benchmark rate as a replacement to the then-current Benchmark for Dollar-denominated repurchase facilities and (ii) the related Benchmark Administration Changes; provided that, no such Benchmark Replacement Rate as so determined would be less than 0%.

(b)The Series 2017-VF1 Indenture Supplement is hereby amended by deleting the definitions of “Benchmark,” “Benchmark Transition Event” and “Note Interest Rate” from Section 2 thereof in their entirety and replacing them with the following:

“Benchmark” means, with respect to any date of determination, the Adjusted Daily Simple SOFR or, if applicable, a Benchmark Replacement Rate.  It is understood that the Benchmark shall be adjusted on a daily basis; provided, that, Benchmark for the three (3) Business Days prior to the related Payment Date shall be fixed at Benchmark for the third (3rd) Business Day prior to the related Payment Date.

“Benchmark Transition Event” means a determination by Administrative Agent in its sole and good faith discretion that, by reason of circumstances affecting the relevant market, (i) adequate and reasonable means do not exist for ascertaining the Benchmark, (ii) the applicable Benchmark is permanently or indefinitely no longer in existence, (iii) continued implementation of the Benchmark is no longer administratively feasible or no significant market practice for the administration of the Benchmark exists, (iv) the Benchmark will not adequately and fairly reflect the cost to Noteholder of purchasing or maintaining Note (including increases in the balance thereof) going forward or (v) the administrator of the applicable Benchmark or a Relevant Governmental Body having jurisdiction over Noteholder or Administrative Agent has made a public statement identifying a specific date after which the Benchmark shall no longer be made available or used for determining the interest rate of loans or other extensions of credit.

“Note Interest Rate” means, for the Series 2017-VF1 Notes, with respect to any Interest Accrual Period, the sum of (a) the greater of (i) the Benchmark (as determined by the Administrative Agent) and (ii) 0.50% plus (b) the Margin.

(c)Section 2 of the Series 2017-VF1 Indenture Supplement is hereby amended by deleting the definitions of “Benchmark Determination Date,” “Benchmark Rate,” “Benchmark Reference Agreement,” “Benchmark Reference Time,” “Benchmark Replacement,” “Benchmark Replacement Adjustment,” “Benchmark Replacement Conforming Changes,” “Benchmark Replacement Date,” “Compounded SOFR,” “Corresponding Tenor,” “Designated Transaction Representative,” “Early Opt-in Effective Date,” “Early Opt-in Election,” “ISDA Definition,” “ISDA Fallback Adjustment,” “ISDA Fallback Rate,” “LIBOR,” “LIBOR Index Rate,” “LIBOR01 Page,” “London Banking Day” “Term SOFR” and “Unadjusted Benchmark Replacement” in their entirety.

(d)Section 8 of the Series 2017-VF1 Indenture Supplement is hereby amended by deleting in its entirety and replacing it with the following:

Section 8.Determination of Note Interest Rate and Benchmark.

(a)Two (2) Business Days immediately preceding the related Payment Date, the Administrative Agent will provide to the Calculation Agent the Benchmark for each day of the related Interest Accrual Period for the Series 2017-VF1 Notes on the basis of the procedures specified in the definition of Benchmark.

4

(b)The Calculation Agent shall calculate the Note Interest Rate for the related Interest Accrual Period and the Interest Payment Amount for the Series 2017-VF1 Notes on each Payment Date, and include a report of such amount in the related Payment Date Report.

(c)The establishment of the Benchmark by the Administrative Agent and the Calculation Agent’s subsequent calculation of the Note Interest Rate and the Interest Payment Amount on the Series 2017-VF1 Notes for the relevant Interest Accrual Period, in the absence of manifest error, will be final and binding.

(d)For purposes of calculating the Required Reserve Amount under the PC Repurchase Agreement, the “Pricing Rate” with respect to any “MRA Payment Date” thereunder will be calculated using the Benchmark as reported by the Administrative Agent for the immediately preceding Payment Date.

(e)Section 15 of the Series 2017-VF1 Indenture Supplement is hereby amended by deleting in its entirety and replacing it with the following:
