 [REVERSE OF FORM OF NOTE] 

THE AES CORPORATION 
 FLOATING
RATE NOTE DUE 2019 
 1. Interest. THE AES CORPORATION, a Delaware corporation (the “Company,” which definition
shall include any successor thereto in accordance with the Indenture (as defined below)), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on the reverse side hereof at a
rate per annum equal to the three-month LIBOR rate (as defined below), as determined on the applicable Interest Determination Date (as defined below) by the Calculation Agent (as defined below), plus 3.00%. 

Interest on the Notes will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid,
from May 20, 2014 through but excluding the date on which interest is paid. Interest shall be payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year (each an “Interest
Payment Date”), commencing September 1, 2014. 
 The rate of interest will be reset on the first day of each Interest Period
other than the Initial Interest Period (as defined below) (the date on which each such reset occurs, an “Interest Reset Date”). An “Interest Period” means the period commencing on an Interest Payment Date (or, in
the case of the Initial Interest Period, commencing on May 20, 2014) and ending on the day preceding the next following Interest Payment Date. The “Initial Interest Period” will be May 20, 2014 through August 31,
2014. The “Interest Determination Date” for an Interest Period will be the second London Business Day preceding the first day of such Interest Period (or, in the case of the Initial Interest Period, the second London Business Day
preceeding May 20, 2014 ). 
 If an Interest Payment Date, other than the Interest Payment Date that coincides with the Maturity Date,
falls on a day that is not a Business Day, the interest payment will be postponed to the next day that is a Business Day and no interest on such postponed payment will be due. If the Maturity Date falls on a day that is not a Business Day, the
payment of interest and principal will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the Maturity Date. 

The amount of interest for each day that the Notes are outstanding (the “Daily Interest Amount”) will be calculated by
dividing the interest rate for the applicable Interest Period by 360 and multiplying the result by the principal amount of the Notes outstanding on such day. The amount of the interest to be paid on the Notes for each interest period will be
calculated by adding such Daily Interest Amounts for each day in the Interest period. 
 Notwithstanding the foregoing, the interest rate of
the Notes in any Interest Period shall in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States laws of general application. 

  
 A-3 








 “Business Day” means any Monday, Tuesday, Wednesday, Thursday or Friday that is
not a day on which banking institutions in the City of New York are authorized or obligated by law or executive order to be closed that is also a London Business Day. 

“London Business Day” means any day on which dealings in United States dollars are transacted on the London interbank market.

 “LIBOR” will be determined by the Calculation Agent in accordance with the following provisions: 

(i) With respect to any Interest Determination Date, LIBOR will be the rate for deposits in United States dollars having a maturity of three
months commencing on the second London Business Day following such Interest Determination Date that appears on Reuters Screen LIBOR01 Page (as defined below) as of 11:00 a.m., London time, on that Interest Determination Date. If no rate appears,
then LIBOR, in respect of that Interest Determination Date, will be determined in accordance with the provisions described in (ii) below. 

(ii) With respect to an Interest Determination Date on which no rate appears on Reuters Screen LIBOR01 Page, as specified in (i) above,
the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Calculation Agent, to provide the Calculation Agent with its offered quotation for deposits in
United States dollars for the period of three months, commencing on the second London Business Day following such Interest Determination Date, to prime banks in the London interbank market at approximately 11 :00 a.m., London time, on that Interest
Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that Interest Determination Date will be the
arithmetic mean of those quotations. If fewer than two quotations are provided, then LIBOR on the Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11 :00 a.m., in the City of New York, on the Interest
Determination Date by three major banks in the City of New York selected by the Calculation Agent for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a
single transaction in United States dollars in that market at that time; provided, however, that if the banks selected by the Calculation Agent are not providing quotations in the manner described by this sentence, LIBOR will be the same as the rate
determined for the immediately preceding Interest Period. 
 “Reuters Screen LIBOR01 Page” means the display designated on
page “LIBOR01” on Reuters (or such other page as may replace the LIBOR01 page on that service or any successor service for the purpose of displaying London interbank offered rates for U.S. dollar deposits of major banks). 

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a
percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.986865% (or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all dollar amounts used in or resulting from such calculations will be rounded to
the nearest cent (with one-half cent being rounded upwards). 

  
 A-4 








 The Calculation Agent (defined below) shall calculate the interest rate in accordance with the
foregoing. On or before each Calculation Date (as defined below), the Calculation Agent will determine the interest rate and notify the Paying Agent. The Calculation Agent will, upon the request of any Holder of the Notes, provide the interest rate
then in effect with respect to the Notes. All calculations of the Calculation Agent, in the absence of manifest error, shall be conclusive for all purposes and binding on the Company and the Holders of the Notes and neither the Trustee nor the
Paying Agent shall have the duty to verify determinations of interest rates made by the Calculation Agent. 
 “Calculation
Date” pertaining to any Interest Determination Date on a Security will be the earlier of (i) the tenth calendar day after such Interest Determination Date, or, if any such day is not a Business Day, the next succeeding Business Day,
and (ii) the Business Day immediately preceding the applicable Interest Payment Date or the Maturity Date, as the case may be. 
 2.
Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the fifteenth calendar day prior to each Interest Payment Date (each, a
“Regular Record Date”), whether or not a Business Day. However, interest on the Notes paid on the Maturity Date will be payable to the person to whom the principal is payable. Holders must surrender Notes to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. At the Company’s option, interest may be paid by check
mailed to the registered address of the Holder of this Note. 
 3. Paying Agent and Registrar. Initially, Wells Fargo Bank, N.A. (the
“Trustee”) will act as Paying Agent, Registrar and Calculation Agent. The Company may change any Paying Agent, Registrar or co-Registrar or Calculation Agent without notice. 

4. Indenture. The Company issued the Notes under an Indenture dated as of December 8, 1998 between the Company and the Trustee as
supplemented by the Ninth Supplemental Indenture dated as of April 3, 2003 and the Eighteenth Supplemental Indenture dated as of May 20, 2014 between the Company and the Trustee (said Indenture, as so supplemented, the
“Indenture”). This Note is one of an issue of Securities of the Company issued under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) as amended from time to time. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture and such Act for a statement of them. Capitalized terms used
herein and not otherwise defined have the meanings set forth in the Indenture. The Notes are general unsecured and unsubordinated obligations of the Company ranking pari passu with all of the Company’s unsecured and unsubordinated obligations.
The Company may, subject to the terms of the Indenture and applicable law, issue Additional Notes under the Eighteenth Supplemental Indenture. The Notes issued on May 20, 2014 and any Additional Notes subsequently issued shall be treated as a
single class for all purposes of the Eighteenth Supplemental Indenture. The Indenture limits the ability of the Company to incur certain secured indebtedness and to enter into certain sale and leaseback transactions. 

  
 A-5

Additional Notes) at a redemption price equal to 100% of the aggregate principal amount of the Notes redeemed, plus a premium equal to the interest rate per annum on the Notes in effect on the date of the notice of redemption, plus accrued and

(B) all required remaining scheduled interest payments due on such Note through June 1, 2015, assuming that the rate of interest on the Notes for the period from the redemption date through June 1, 2015 will be equal to the rate of
interest on the Notes in effect on the date on which the applicable notice of redemption is given (excluding accrued but unpaid interest, if any, to, but not including, the redemption date) computed using a discount rate equal to the Treasury Rate

than 25% in aggregate principal amount of the outstanding Notes may, or the Trustee may, by written notice to the Company, and the Trustee at the request of not less than 25% in aggregate principal amount of the outstanding Notes will, declare the

accrued interest on all of the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities of
all series issued under the Indenture that are affected may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing default (except a default in payment of principal or
interest) if it determines in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 

14. Trustee Dealing with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 

15. No Recourse Against Others. A director, officer, employee, stockholder or beneficiary, as such, of the Company shall not have any
liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issue of the Notes. 
 16. Defeasance. The Indenture contains
provisions (which provisions apply to this Note) for defeasance at any time of (a) the entire indebtedness of the Company in respect of this Note and (b) certain restrictive covenants and Defaults and Events of Default, in each case upon
compliance by the Company with certain conditions set forth therein. 
 17. Authentication. This Note shall not be valid until the
Trustee signs the certificate of authentication on the other side of this Note. 
 18. Abbreviations. Customary abbreviations may be
used in the name of a Holder of Notes or an assignee, such as: TEN COM (= tenants in common), TENANT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and
