Company at an initial exchange rate of 30.6828 shares per $1,000 principal amount of Debentures. At the initial exchange rate, the Debentures are exchangeable for common stock of the Company at an exchange price of $32.5916 per share, representing
an approximately 18.0% premium over the last reported sale price of the common stock of the Company on August&nbsp;9, 2006, which was $27.62 per share. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
