As described above, the entire unpaid principal amount of this Class A(2021-1) Note shall be due and payable on the Legal Maturity Date. Notwithstanding the foregoing, the entire unpaid principal amount of the Class A(2021-1) Notes shall be due and payable on the date on which an Event of Default relating to the Class A(2021-1) 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(2021-1) 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of the Indenture; provided, however, that such acceleration of the entire unpaid principal amount of the Notes may be rescinded by the Majority Holders of such applicable Series, Class or Tranche of Notes.

Such checks shall be mailed to the Person entitled thereto at the address of such Person as it appears on the Note Register as of the applicable Record Date without requiring that this Class A(2021-1) Note be submitted for notation of payment. Any reduction in the principal amount of this Class A(2021-1) Note (or any one or more Predecessor Notes) effected by any payments made on any Payment Date shall be binding upon all future Holders of this Class A(2021-1) Note and of any Class A(2021-1) Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon.

The Indenture also contains provisions permitting the Holders of Notes representing specified percentages of the Outstanding Dollar Principal Amount of the Notes, on behalf of the Holders of all the Notes, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Class A(2021-1) Note shall be conclusive and binding upon such Holder and upon all future Holders of this Class A(2021-1) 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(2021-1) Note. The Indenture also permits the Indenture Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of Holders of the Notes issued thereunder.
