        <footnote id="F1">Based on performance in 2003, the filing individual earned incentive income.  Under the terms of the Company's Executive Annual Incentive Plan, the filing individual chose to defer 25% of her 2003 incentive income into phantom stock units purchased at 80% of the market value of Entergy Corporation common stock on 12/31/03 and held in a brokerage account.  Entergy Corporation common stock closed at 57.13 on 12/31/03.  On March 11, 2004, the amount of 2003 incentive income under the Executive Annual Incentive Plan was determined with finality for the filing individual, and the phantom stock units were placed in the brokerage account.  The deferral period is until the earlier of January 2, 2006 or retirement from the Company.</footnote>
        <footnote id="F2">These represent restricted phantom stock units under the Company's 2001-2003 Long Term Incentive Plan.  On March 11, 2004, the filing individual received a cash pay-out for the 7,500 units earned under the LTIP.</footnote>
