(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. In this case, the Board Year commenced on April 28, 2005 and will continue through April 26, 2006. A Non Employee Director is not eligible to make a withdrawl from his deferred acccount until such Director ceases to be a Board Member. This distribution 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.
(2) Mr. Lader elected the Stock Option Grant as a component of his Director Compensation for Board Year 2005-2006.
