(1) The sales price is a weighted average for the transactions which took place on September 28, 2010. The sales prices range from a low of $12.20 per share to a high of $12.41 per share. Full information regarding the number of shares sold at each separate price is available upon request by the Commission staff, PolyOne Corporation, or a security holder of PolyOne Corporation.
(2) The information in this report is based on a PolyOne Retirement Savings Plan statement as of September 26, 2010. PolyOne common shares are held in a unitized fund that consists of stock and cash. The number of shares and the amount of cash may fluctuate daily depending on plan level activity in the fund. Even though no transaction has occured, this fluctuation may result in an increase or decrease in the number of shares held since the last report filed by the reporting person.
(3) SARs become exercisable and vest one-third on the attainment of 10%, 20% and 30% stock appreciation (which must be maintained for a minimum of three consecutive trading days) from the grant date closing price of $1.43 per share, with no more than one-third vesting per year during the first three years.
