If funds are expected to be available, as provided in the Indenture, for payment in full of the then-remaining unpaid principal amount of this Series 2022-A Bond on a Payment Date, then the Indenture Trustee, in the name of and on behalf of the Issuer, will notify the Person who was the Registered Holder hereof as of the Record Date preceding such Payment Date by notice sent no later than five (5) days prior to such final Payment Date and shall specify that such final installment will be payable only upon presentation and surrender of this Series 2022-A Bond and shall specify the place where this Series 2022-A Bond may be presented and surrendered for payment of such installment.

Each Holder, by acceptance of a Series 2022-A Bond, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer or the Indenture Trustee on the Series 2022-A Bonds or under the Indenture or any certificate or other writing delivered in connection therewith, against (a) any owner of a membership interest in the Issuer (including KGS) or (b) any shareholder, partner, owner, beneficiary, agent, officer or employee of the Indenture Trustee, the Managers or any owner of a membership interest in the Issuer (including KGS) in its respective individual or corporate capacities, or of any successor or assign of any of them in their individual or corporate capacities, except as any such Person may have expressly agreed in writing. Each Holder by accepting a Series 2022-A Bond specifically confirms the nonrecourse nature of these obligations and waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Series 2022-A Bonds.

Prior to the due presentment for registration of transfer of this Series 2022-A Bond, the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Series 2022-A Bond is registered (as of the day of determination) as the owner hereof for the purpose of receiving payments of principal of and premium, if any, and interest on this Series 2022-A Bond and for all other purposes whatsoever, whether or not this Series 2022-A Bond be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected by notice to the contrary.

Any such consent or waiver by the Holder of this Series 2022-A Bond (or any one of more Predecessor Series 2022-A Bonds) shall be conclusive and binding upon such Holder and upon all future Holders of this Series 2022-A Bond and of any Series 2022-A Bond 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 Series 2022-A Bond. 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 issued thereunder, but with the satisfaction of the Kansas Commission Condition.
