The 2029 Debentures will have an initial conversion price of $28.8656, which is equal to 125% of the Average VWAP. The initial conversion rate for the 2029 Debentures will be 34.6433 per $1,000 principal amount of 2029 Debentures, or 1,000 divided by the initial conversion price.

The initial conversion price and initial conversion rate for the 2029 Debentures has been determined based on the "Average VWAP". The "Average VWAP" means the arithmetic average, as determined by the Company, of the Daily VWAP for each trading day during the ten trading day period ending on and including August 21, 2009, rounded to four decimal places. The "Daily VWAP" for any trading day means the per share volume weighted average price of the Company's common stock on that day as displayed under the heading Bloomberg VWAP on Bloomberg Page WCC.N<Equity>AQR (or its equivalent successor page if such page is not available) in respect of the period from the scheduled open of trading on the relevant trading day until the scheduled close of trading on the relevant trading day (or if such volume weighted average price is unavailable, the market price of one share of the Company's common stock on such trading day determined, using a volume weighted average method, by a nationally recognized investment banking firm retained by the Company for this purpose). The Average VWAP has been determined to be $23.0925.

As a result of the determination of the Average VWAP, the "Reference Price" for the purposes of calculating the adjustment to the conversion rate applicable in the case of certain non-stock change of control transactions is $23.0925. In addition, the "Initial Conversion Value" for the purposes of calculating the amount payable by the Company upon a tax related redemption of the 2029 Debentures is $800.0004.
