ILLINOIS COMPANY, a corporation organized and existing under the laws of the State of Illinois (the “Company”), which term shall include any successor corporation within the meaning of the Indenture hereinafter referred to, for value
received, hereby promises to pay to The Bank of New York Mellon Trust Company, N.A., as trustee (the “CIPS Trustee”) under the Indenture dated as of December 1, 1998 (as amended and supplemented, the “CIPS Indenture”),
relating to the Company’s 6.625% Senior Notes due 2011 (the “2011 Notes”) in the aggregate principal amount of $150,000,000, between the Company and the CIPS Trustee, or registered assigns, the principal sum of $150,000,000 on
June 15, 2011, in any coin or currency of the United States of America, which at the time of payment is legal tender for public and private debts, and to pay interest thereon in like coin or currency from the date of issuance (and thereafter
from the dates set forth in the 2011 Notes), and at the same rate of interest as the 2011 Notes. Interest on overdue principal, premium, if any, and, to the extent permitted by law, on overdue interest, shall be payable at the interest rate
payable on the 2011 Notes. Interest on this Note is payable on the same dates as interest on the 2011 Notes is paid, until the principal sum of this Note is paid in full. Pursuant to Article XVI of the CIPS Indenture, this Note is
issued to the CIPS Trustee to secure any and all obligations of the Company under the 2011 Notes and any other series of senior notes from time to time outstanding under the CIPS Indenture. Payment of principal of, or premium, if any, or
interest on, the 2011 Notes shall constitute payments on this Note as further provided herein and in the Supplemental Indenture of October 1, 2010 (as hereinafter defined) pursuant to which this Note has been issued. Both the principal of,
premium, if any, and the interest on, this Note are payable at the office of the CIPS Trustee. 
 Upon any payment of the
principal of, premium, if any, and interest on, all or any portion of the 2011 Notes, whether at maturity or prior to maturity by redemption or otherwise or upon provision for the payment thereof having been made in accordance with
Section 5.01(a) of the CIPS Indenture, a principal amount of this Note equal to the principal amount of such 2011 Notes shall, to the extent of such payment of principal, premium, if any, and interest, be deemed paid and the obligation of
the Company thereunder to make such payment shall be discharged to such extent and, in the case of the payment of principal (and premium, if any), such Notes shall be surrendered to the Company for cancellation as provided in Section 16.08 of
the CIPS Indenture. The Trustee (as hereinafter defined) may at any time and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of, premium, if any, and interest on, the 2011 Notes,
so far as such payments at the time have become due, has been fully satisfied and discharged pursuant to the foregoing sentence unless and until the Trustee shall have received a written notice from the CIPS Trustee signed by one of its officers
stating (i) that timely payment of principal of, premium, if any, or interest on, the 2011 Notes has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the CIPS Trustee pursuant to the CIPS
Indenture, and (iii) the amount of the arrearage. 
 For purposes of Section 16.09 of the CIPS Indenture, this Note
shall be deemed to be the “Related Series of IP Senior Notes” in respect of the 2011 Notes. 







 This Note shall not be entitled to any benefit under the Indenture or any indenture
supplemental thereto, or become valid or obligatory for any purpose, until the form of certificate endorsed hereon shall have been signed by or on behalf of The Bank of New York Mellon Trust Company, N.A. as the trustee under the Indenture, or a
successor trustee thereto under the Indenture (the “Trustee”). 
 The provisions of this Note are continued on the
reverse hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place. 







 IN WITNESS WHEREOF, Ameren Illinois Company has caused this instrument to be duly executed.

under the Mortgage and the rights of the Company and of the Mortgage Trustee in respect thereof, the duties and immunities of the Mortgage Trustee and the terms and conditions upon which the Senior Note Mortgage Bonds are secured and the

 This Series CIPS-BB Note is subject to redemption in
