[1] Exercise prices exceed the average market price of the common shares or are anti-dilutive due to the impact of the unrecognized compensation cost on the calculation of assumed proceeds in the application of the treasury stock method.

[2] We issued $575 million of senior convertible notes in June 2007. The impact of a net share settlement of the conversion amount at maturity will begin to dilute earnings per share if and when our stock price reaches $53.40. The impact of stock that could be issued to settle share obligations we could have under the warrants we issued simultaneously with the convertible notes issuance will begin to dilute earnings per share when our stock price reaches $68.10. The potential receipt of MCBC stock from counterparties under our purchased call options when and if our stock price is between $53.40 and $68.10 would be anti-dilutive and excluded from any calculations of earnings per share.
