“Section 2.11 Security. The payments of principal of and interest on the Series 2023-A Notes and Series 2024-A Notes shall be secured by the Trust Estate, including an assignment by the Trustee to the Servicer of the Proceeds Disbursing Agreement, including all Obligor Payments and other amounts payable to the Trustee under the Proceeds Disbursing Agreement, the cash balances in the Payment Reserve Fund and other funds maintained by the Trustee. In addition, as provided in the Insurance Policy, to the extent other amounts are insufficient to pay debt service on the Series 2023-A Notes when due, payments made by the Insurer under the Insurance Policy may be used to make such payments. All funds established in this Indenture for the benefit of the Series 2023-A Notes are pledged and assigned under the Transaction Documents for the equal and proportionate benefit of the registered holders of the Series 2023-A Notes and, except as otherwise provided in the Transaction Documents, may be used for no purpose other than payment of the Series 2023-A Notes. All funds established in this Indenture for the benefit of the Series 2024-A Notes are pledged and assigned under the Transaction Documents for the equal and proportionate benefit of the registered holders of the Series 2024-A Notes and, except as otherwise provided in the Transaction Documents, may be used for no purpose other than payment of the Series 2024-A Notes. The obligation of the Issuer to abide by the terms of the Indenture, the Series 2023-A Notes and the Series 2024-A Notes shall be absolute and unconditional and shall not be subject to any defense or any right of set off, counterclaim or recoupment arising out of any breach by the Trustee or any Noteholder of any obligation to the Issuer or otherwise with respect to the Series 2023-A Notes, the Series 2024-A Notes, or out of any indebtedness or liability at any time owing to the Issuer by the Trustee. Until such time as all of the Series 2023-A Notes and Series 2024-A Notes shall have been fully paid or redeemed, the Issuer will not suspend or discontinue any payments provided for herein. Notwithstanding the foregoing, the Issuer’s obligation to make payments on the Series 2023-A Notes and Series 2024-A Notes is limited to the components of the Trust Estate. If the sources comprising the Trust Estate do not provide funds sufficient to make payments on the Series 2023-A Notes and Series 2024-A Notes, the Issuer is under no obligation to make such payments. For the avoidance of doubt, the Issuer has an obligation to make all payments in accordance with the Transaction Documents, including the outstanding principal and accrued interest on the Series 2023-A Notes and Series 2024-A Notes. Pursuant to the Trustee Services Agreement, the Trustee has assigned the Trust Estate to the Servicer, other than the Insurance Policy, which has been issued directly to the Trustee as Named Insured. For the avoidance of doubt, notwithstanding anything to the contrary herein, all amounts received under the Insurance Policy shall be applied solely to the payment of the Series 2023-A Notes.”

Notwithstanding any contrary provision hereof, any redemption of the Notes that is effected pursuant to this Indenture shall be made on a pro rata basis among all Noteholders of all Notes (including any Series 2023-A Notes and Series 2024-A Notes) based on the aggregate principal amount of Notes held by each Noteholder.

Upon any such transfer, a new Note or Notes in the same aggregate principal amount and of the same series, interest rate, and maturity will be issued to the transferee. The Issuer and the Trustee may deem and treat the person in whose name this Note is registered as the absolute Holder hereof (whether or not this Note shall be overdue) for the purpose of receiving payment of, or on account of, the principal of, and interest due on this Note and for all other purposes, and the Issuer and the Trustee shall not be affected by any notice to the contrary. Beneficial Ownership Interests in this Note may be transferred so long as the proposed resale, transfer, or other disposition of this Note is exempt from registration under the Securities Act.
