        <footnote id="F1">Mr. Kennedy did not sell any of the 11,295 reported shares.  Rather, this amount represents shares withheld pursuant to the terms of a shareholder-approved stock plan for the payment of withholding taxes due upon the 1/10/10 vesting of 28,083 of the 84,250 shares of restricted stock Mr. Kennedy was granted on 12/8/08.  These withheld shares are not sold on the open market and become Revlon, Inc. treasury shares.</footnote>
        <footnote id="F2">Of these 142,698 shares reflected as beneficially owned, (a) 27,834 shares are unvested restricted shares that the reporting person was granted on 12/10/07 which vest on 1/2/11; (b) 56,167 shares are unvested restricted shares that the reporting person was granted on 12/8/08 which vest in substantially equal installments on 1/10/11 and 1/10/12; and (c) 20,000 shares are shares held in the reporting person's account under the Revlon Employees' Savings, Investment and Profit Sharing Plan.</footnote>
