        <footnote id="F1">SARs are exercisable upon vesting.  Vesting occurs when the market price of the PolyOne common stock reaches pre-determined levels for three consecutive days as follows:  1/3 vests at a market price of $8 per share; an additional 1/3 vests at a market price of $9 per share; and the remaining 1/3 vests at a market price of $10 per share.</footnote>
        <footnote id="F2">The original filing, on 11/18/2004, incorrectly assigned a value of $8.90 to the price of the derivative security.  This field should have been $0, as shown on this amended filing.</footnote>
