(1) Pursuant to the Amended and Restated Deferred Compensation Plan for Directors of The AES Corporation (the "Company"), Non-Employee Directors may elect to defer receipt of compensation otherwise payable to such Director in the form of stock units, the basis of which is determined to be the closing stock price on the day that the Non-Employee Director is elected to the Board of Directors for the Plan Year for which a stock unit election is made. A Non-Employee Director is not eligible to make a withdrawl from his deferred account until such Director ceases to be a Board Member. This distribution (one share of stock for each stock unit) will be made as soon as practicable after the Director leaves the Company, and will be made in accordance with the Director's Distribution Election Notification. Ms. Emerson retired from The AES Corporation Board of Directors on April 27, 2005 and received distribution of her deferred account on May 2, 2005.
