(c) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the Federal Reserve Board, the Federal Reserve Bank of New York or any regulator of Discover Bank announcing that the Benchmark is no longer representative of the underlying market or economic reality, may no longer be used or is otherwise no longer an appropriate or reliable Benchmark for floating rate debt; or

(d) either (i) the Calculation Agent determines in its sole discretion and in good faith that LIBOR is no longer an appropriate or reliable Benchmark for the Class A(2019-2) Notes or (ii) the Calculation Agent has determined in good faith that LIBOR is no longer being used as a benchmark for lending and borrowing activities generally.

(b) If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Class A(2019-2) Notes in respect of such determination on such date and all determinations on all subsequent dates; provided that the Calculation Agent may in its sole discretion delay the date on which the Benchmark Replacement will apply to a date not later than the first day of the second occurring full Interest Accrual Period following the related Benchmark Replacement Date. However, if the initial Benchmark Replacement is any rate other than Term SOFR and the Calculation Agent later determines that Term SOFR can be determined, at the option of the Calculation Agent, Term

13

SOFR shall become the new Unadjusted Benchmark Replacement and will, together with a new Benchmark Replacement Adjustment for Term SOFR, replace the then-current Benchmark on the next Interest Rate Determination Date for Term SOFR. If the Calculation Agent does not provide a Benchmark Replacement for any Interest Accrual Period after the occurrence of a Benchmark Transition Event and its related Benchmark Replacement Date, then, for purposes of calculating the Note Interest Rate for any Interest Accrual Period, the Benchmark shall be LIBOR, which shall be calculated pursuant to the definition set forth in Section 1.01.

(c) In connection with the implementation of a Benchmark Replacement, the Calculation Agent shall have the right to make Benchmark Replacement Conforming Changes from time to time.

(d) Promptly following the determination of a Benchmark Replacement and/or the making of any Benchmark Replacement Conforming Changes, the Calculation Agent will notify the Issuer, and will provide to the Issuer the relevant information regarding the Unadjusted Benchmark Replacement, the Benchmark Replacement Adjustment and any such Benchmark Replacement Conforming Changes for inclusion in the monthly noteholders’ statement. Notwithstanding anything in this Terms Document or the other transaction documents to the contrary, upon the delivery of such notice and the inclusion of such information in the monthly noteholders’ statement, this Terms Document and/or any other relevant transaction document will be deemed to have been amended to reflect such Unadjusted Benchmark Replacement, Benchmark Replacement Adjustment and/or Benchmark Replacement Conforming Changes without further compliance with the provisions of Article X of the Indenture or the amendment provisions of any other relevant transaction document.

(e) Any determination, decision or election that may be made by the Calculation Agent in connection with Section 2.04 (or pursuant to any capitalized term used in Section 2.04 or in any such capitalized term), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, shall be conclusive and binding absent manifest error, may be made in the Calculation Agent’s sole discretion, and, notwithstanding anything to the contrary in the transaction documents, will become effective without consent from any other party. None of the Issuer, the Owner Trustee, the Indenture Trustee, the Calculation Agent, Discover Bank, the Depositor, the Master Trust, the Master Trust Trustee, the Servicer or the underwriters of the Class A(2019-2) Notes shall have any liability for any determination made by or on behalf of the Calculation Agent pursuant to Section 2.04 (or pursuant to any capitalized term used in Section 2.04 or in any such capitalized term), and each Class A(2019-2) Noteholder, by its acceptance of a Class A(2019-2) Note or a beneficial interest in a Class A(2019-2) Note, will be deemed to waive and release any and all claims against the Issuer, the Owner Trustee, the Indenture Trustee, the Calculation Agent, Discover Bank, the Depositor, the Master Trust, the Master Trust Trustee, the Servicer or the underwriters of the Class A(2019-2) Notes relating to any such determinations.

(f) For the avoidance of doubt: (i) in no event will the Indenture Trustee be responsible for (A) other than as set forth in the definition of LIBOR, determining LIBOR or any substitute for LIBOR if such rate does not appear on the Reuters Screen LIBOR01 page or on a comparable system as is customarily used to quote LIBOR or such substitute for LIBOR or (B)

14

making any adjustments to the alternative Benchmark or the spread thereon, the business day convention, interest determination dates and any related provisions and definitions or any other relevant methodology for calculating such substitute or successor Benchmark; and (ii) in connection with any of the matters referenced in clause (i) of this sentence, the Indenture Trustee will be entitled to conclusively rely on any determinations made by the Calculation Agent in regards to such matters and will have no liability for such actions taken at the direction of the Calculation Agent.

As described above, the entire unpaid principal amount of this Class A(2019-2) Note shall be due and payable on the Legal Maturity Date. Notwithstanding the foregoing, the entire unpaid principal amount of the Class A(2019-2) Notes shall be due and payable on the date on which an Event of Default relating to the Class A(2019-2) Notes shall have occurred and be continuing and, except in the event of an insolvency related default, the Indenture Trustee or the Majority Holders of the applicable Series, Class or Tranche of Outstanding Dollar Principal Amount of the Outstanding Notes have declared the Class A(2019-2) Notes to be immediately due and payable in the manner provided in Section 702 of the Indenture; provided, however, that such acceleration of the entire unpaid principal amount of the Notes may be rescinded by the Majority Holders of such applicable Series, Class or Tranche of Notes.

this Class A(2019-2) Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Class A(2019-2) Note.
