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 Tranche A-1 Securitization 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 Tranche A-1 Securitization Bond and shall specify the place where this Tranche A-1 Securitization Bond may be presented and surrendered for payment of such installment.

This Tranche A-1 Securitization Bond is a “securitization bond” as such term is defined in the Securitization Act. Principal and interest on this Tranche A-1 Securitization Bond are payable from and secured primarily by the Securitization Property authorized by the Financing Order.

(1) take or permit any action that would impair the value of securitization property; or

-14-

(2) reduce or alter, except as authorized by section 12(c) of this chapter, or impair securitization charges to be imposed, collected, and remitted to financing parties under this chapter;

until the principal, interest and premium, and other charges incurred, or contracts to be performed, in connection with the related securitization bonds have been paid or performed in full.”

In addition, the Financing Order provides that “the Indiana Commission affirms the pledge of the State of Indiana set forth in Indiana Code § 8-1-40.5-16(b) and will not, unless otherwise permitted by the Securitization Act:

until the principal, interest and premium, and other charges incurred, or contracts to be performed, in connection with the Securitization Bonds have been paid or performed in full.”

The Issuer acknowledges that the purchase of this Tranche A-1 Securitization Bond by the Holder hereof or the purchase of any beneficial interest herein by any Person are made in reliance on the foregoing pledges by the State of Indiana and the Indiana Commission.

No service charge will be charged for any registration of transfer or exchange of this Tranche A-1 Securitization Bond, but the transferor may be required to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 2.04 or Section 2.06 of the Indenture not involving any transfer.

Each Holder, by acceptance of a Tranche A-1 Securitization 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 Tranche A-1 Securitization 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 CEI South) 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 CEI South) 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 Tranche A-1 Securitization 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 Tranche A-1 Securitization Bonds.

Prior to the due presentment for registration of transfer of this Tranche A-1 Securitization Bond, the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Tranche A-1 Securitization 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 Tranche A-1 Securitization Bond and for all other purposes whatsoever, whether or not this Tranche A-1 Securitization Bond be overdue, and none of the Issuer, the Indenture Trustee or any such agent shall be affected by notice to the contrary.
