 AMEREN ILLINOIS COMPANY, a corporation of the State of Illinois (the “COMPANY”), for value

Issue Date specified above or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on March 1 and September 1 in each year, commencing March 1, 2013,
and on the Maturity Date, at the per annum Interest Rate set forth above until the principal hereof is paid or made available for payment. No interest shall accrue on the Maturity Date, so long as the principal amount of this Note is paid on the
Maturity Date. The interest so payable and punctually paid or duly provided for on any such Interest Payment Date (except for interest payable on the Maturity Date set forth above or, if applicable, upon redemption or acceleration), will, as
provided in the Indenture (as defined below), be paid to the Person in whose name this Note is registered at the close of business on the Regular Record Date for such interest, which shall be February 15 or August 15, as the case may be,
next

applicable Interest Payment Date, shall be the Interest Payment Date following the next succeeding Regular Record Date; and provided, that interest payable on the Maturity Date set forth above or, if applicable, upon redemption or acceleration,
shall be payable to the Person to whom principal shall be payable. Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record
Date and shall be paid to the Person in whose name this Note is registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Noteholders not more
than fifteen days nor fewer than ten days prior to such Special Record Date. Payment of the principal of and interest and premium on this Note shall be payable pursuant to Section 2.12(a) of the Indenture. 

This Note is a Global Note in respect of a duly authorized issue of 2.70% Senior Secured Notes due 2022 (the “NOTES OF THIS
SERIES”, which term includes any Global Notes representing such Notes) of the Company issued and to be issued under an Indenture dated as of June 1, 2006 between the Company (as successor to Illinois Power Company) and The Bank of New York
Mellon Trust Company, N.A., as trustee (herein called the “TRUSTEE”, which term includes any successor Trustee under the Indenture) and indentures supplemental thereto (collectively, the “INDENTURE”). Under the Indenture, one or
more series of notes may be issued and, as used herein, the term “Notes” refers to the Notes of this Series and any other outstanding series of Notes. Reference is hereby made to the Indenture for a more complete statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Noteholders and of the terms upon which the Notes are and are to be authenticated and delivered. This Note has been issued in respect of
the series designated on the first page hereof, issued in the initial aggregate principal amount of $400,000,000. 
 The Notes
will be secured by first mortgage bonds (the “SENIOR NOTE MORTGAGE BONDS”) delivered by the Company to the Trustee for the benefit of the Holders of the Notes, issued under the General Mortgage Indenture and Deed of Trust, dated as of
November 1, 1992 between the Company and The Bank of New York Mellon Trust Company, N.A., as successor trustee (the “MORTGAGE TRUSTEE”), as supplemented and modified (collectively, the “MORTGAGE”). Reference is made to the
Mortgage and the Indenture for a description of the rights of the Trustee as holder of the Senior Note Mortgage Bonds, the property mortgaged and pledged, the nature and extent of the security and the rights of the holders of first mortgage bonds
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
circumstances under which additional first mortgage bonds may be issued. 
 So long as any of the Notes of this Series are
outstanding, the Company will not permit a Release Date to occur. 
 Each Note of this Series shall be dated and issued as of
the date of its authentication by the Trustee and shall bear an Original Issue Date. Each Note of this Series issued upon transfer, exchange or substitution of such Note shall bear the Original Issue Date of such transferred, exchanged or
substituted Note, as the case may be. 

  
 2 

 Interest on this Note will accrue from and including the Original Issue Date specified above
to, but excluding, March 1, 2013, and thereafter, from and including each Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, the Maturity Date or any redemption date, as the case may be. 

All or a portion of the Notes of this Series may be redeemed at the option of the Company at any time or from time to time. The
redemption price for the Notes of this Series to be redeemed on any redemption date prior to June 1, 2022 (three months prior to the Maturity Date) will be equal to the greater of the following amounts: (a) 100% of the principal amount of
the Notes of this Series being redeemed on the redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes of this Series being redeemed on that redemption date (not including
any portion of any payments of interest accrued to the redemption date) discounted to the redemption date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Reference Treasury Dealer (as
defined below), plus, in each case, accrued and unpaid interest thereon to the redemption date. The redemption price for the Notes of this Series to be redeemed on any redemption date on or after June 1, 2022 will be equal to 100% of the
principal amount of the Notes of this Series being redeemed on the redemption date plus accrued and unpaid interest thereon to the redemption date. Notwithstanding the foregoing, installments of interest on Notes of this Series that are due and
payable on Interest Payment Dates falling on or prior to a redemption date will be payable on the Interest Payment Date to the Holder of this Note as of the close of business on the relevant Regular Record Date. The redemption price will be
calculated on the basis of a 360-day year consisting of twelve 30-day months. 
 The Company shall mail notice of any redemption
at least 30 days but not more than 60 days before the redemption date to each Holder of the Notes of this Series to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to
accrue on the Notes of this Series or portions thereof called for redemption. 
 Any notice of redemption at the Company’s
option may state that such redemption will be conditional upon receipt by the Trustee, on or prior to the redemption date, of money sufficient to pay the principal of and premium, if any, and interest on, the Notes of this Series or portions thereof
called for redemption, and that if such money has not been so received, such notice will be of no force and effect and the Company will not be required to redeem such Notes or portions thereof. 

“ADJUSTED TREASURY RATE” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 

  
 3 

 “COMPARABLE TREASURY ISSUE” means the United States Treasury security selected by
the Reference Treasury Dealer as having a maturity comparable to the remaining term of the Notes of this Series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term of such Notes of this Series. 

“COMPARABLE TREASURY PRICE” means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer
Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such
quotations, or (C) if only one Reference Treasury Dealer Quotation is received, such quotation. 
 “REFERENCE TREASURY
DEALER” means (A) Deutsche Bank Securities Inc., J.P. Morgan Securities LLC or UBS Securities LLC or their respective affiliates which are primary U.S. Government securities dealers in the United States (each, a “Primary Treasury
Dealer”), and their respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer; and (B) any other Primary
Treasury Dealer(s) selected by the Company. 
 “REFERENCE TREASURY DEALER QUOTATIONS” means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Company by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding such redemption date. 
 Interest payments for this Note shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months (and for any partial periods shall be calculated on the basis of the number of
days elapsed in a 360-day year of twelve 30 day months). If any Interest Payment Date falls on a day that is not a Business Day, the Interest Payment Date will be the next succeeding Business Day (and without any interest or other payment in respect
of any such delay). If the Maturity Date of this Note or any redemption date falls on a day that is not a Business Day, the payment of principal, premium, if any, and interest will be made on the next succeeding Business Day with the same force and
effect as if made on such Maturity Date or redemption date, and no interest on such payment shall accrue for the period from and after the Maturity Date or such redemption date. 

The Company, at its option, and subject to the terms and conditions provided in the Indenture, will be discharged from any and all
obligations in respect of the Notes of this Series (except for certain obligations including obligations to register the transfer or exchange of Notes of this Series, replace stolen, lost or mutilated Notes of this Series, maintain paying agencies
and hold monies for payment in trust, all as set forth in the Indenture) if the Company deposits with the Trustee money, U.S. Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms
will provide money, or a combination of money and U.S. Government Obligations, in any event in an amount sufficient, without reinvestment, to pay all the principal of and any premium and interest on the Notes of this Series on the dates such
payments are due in accordance with the terms of the Notes of this Series. 

  
 4 

 If an Event of Default shall occur and be continuing with respect to the Notes, the
principal of and interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture and, upon such declaration, the Trustee shall demand the redemption of the Senior Note Mortgage Bonds to the extent
provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modifications of the rights and obligations of the Company and the rights of the Noteholders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the
outstanding Notes. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange
therefor or in lieu thereof whether or not notation of such consent or waiver is made upon this Note. 
 As set forth in and
subject to the provisions of the Indenture, no Holder of any Notes will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written
notice of a continuing Event of Default with respect to such Notes, the Holders of a majority in aggregate principal amount of the outstanding Notes affected by such Event of Default shall have made written request and offered reasonable indemnity
to the Trustee to institute such proceeding as Trustee and the Trustee shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement
of payment of the principal of and any premium or interest on this Note on or after the respective due dates expressed herein. 

No reference herein to the Indenture and to provisions of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the times, places and rates and the coin or currency prescribed in the Indenture. 

As provided in the Indenture and subject to certain limitations therein set forth, this Note may be transferred only as permitted by the
legend hereto and the provisions of the Indenture. 
 The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the State of New York without regard to conflicts of law principles thereof. 
 Unless the
certificate of authentication hereon has been executed by the Trustee, directly or through an Authenticating Agent by manual signature of an authorized officer, this Note shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose. 
 All terms used in this Note that are defined in the Indenture shall have the meanings assigned to
them in the Indenture unless otherwise indicated herein.
