The exact stock prices and effective dates may not be set forth in the table above, in which case:

•		if the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares by which the conversion rate will be increased will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year;
•		if the stock price is greater than $60.00 per share (subject to adjustment), no additional shares will be added to the conversion rate; and
•		If the stock price is less than $7.24 per share (subject to adjustment), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion of Notes exceed 138.1215 per $1,000 principal amount of such Notes, subject to adjustments in the same manner as the applicable conversion rate as set forth under “Description of the Notes—Conversion rate adjustments” in the preliminary prospectus supplement dated September 30, 2009.
