Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) These shares represent matching and profit sharing awards for year 2004. The 2004 profit sharing award was determined by the Board of Directors on 02-25-2005. The average stock price for the year was $9.9715.
(2) The restricted stock unit award, pursuant to The AES Corporation 2003 Long Term Compensation Plan, vests in three annual equal installments if certain performance criteria are achieved. They are subject to a deferred payment date, which is the fifth anniversary of the grant date. The payment amount of the award, if any, equals the market value of the stock on the fifth anniversary of the grant date.
(3) These units are awarded pursuant to the Restoration Supplemental Retirement Plan. Participants are eligible to receive a supplemental profit sharing award for each plan year in which the Company's contribution to The AES Corporation Profit Sharing and Stock Ownership Plan is limited by IRS Code requirements. Such an award was made to Mr. Hemphill on 02-25-2005 as determined by the Board of Directors. Benefits under this Plan shall be paid as soon as practicable following termination of employment. Each unit is equal to one share of stock.
(4) These units are awarded pursuant to the Restoration Supplemental Retirement Plan. Mr. Hemphill has elected to defer receipt of compensation otherwise payable to him in the form of stock units, the basis of which is determined to be the Company closing stock price on the last day of each month. The Plan allows for distribution of deferred amounts upon a date(s) specified by the participant, in the event of the participant's unforeseeable emergency, death or termination of employment. This amount represents Mr. Hemphill's February 2005 deferral.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
