     Adjustment to Shares Delivered upon Conversion upon Certain Fundamental Changes.

     If holder elects to convert notes in connection with a make-whole fundamental change, we will increase the conversion rate for the notes surrendered for conversion by a number of additional shares of our common stock, as described below.

     The following table sets forth the hypothetical stock price and the number of additional shares to be received per $1,000 principal amount of notes:

Stock price on fundamental change date

Effective date		$32.15				$40.00				$50.00				$60.00				$70.00				$80.00				$90.00				$100.00				$110.00				$120.00				$130.00				$140.00				$150.00
6/2/2009			7.1778				6.3989				4.0680				2.7512				1.9456				1.4227				1.0672				0.8162				0.6336				0.4974				0.3936				0.3131				0.2498
6/1/2010			7.1778				6.3021				3.8812				2.5482				1.7544				1.2527				0.9200				0.6905				0.5271				0.4073				0.3176				0.2491				0.1958
6/1/2011			7.1778				5.9720				3.4948				2.1858				1.4404				0.9897				0.7031				0.5131				0.3822				0.2891				0.2210				0.1701				0.1312

6/1/2013			7.1778				4.1101				1.7098				0.7437				0.3503				0.1849				0.1111				0.0749				0.0547				0.0418				0.0326				0.0253				0.0193

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

	(1)		If the stock price is between two stock price amounts 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 price amounts and the two dates, as applicable, based on a 365-day year.
	(2)		If the stock price is greater than $150.00 per share (subject to adjustment), no additional shares will be added to the conversion rate.
	(3)		If the stock price is less than $32.15 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 the notes exceed 31.1041 per $1,000 principal amount of notes, subject to adjustments in the same manner as the conversion rate as set forth under “—Conversion Rate Adjustments.”

     In addition, if a holder of notes elects to convert its notes prior to the effective date of any fundamental change, and the fundamental change does not occur, such holder will not be entitled to an increased conversion rate in connection with such conversion.

     Our obligation to satisfy the additional shares requirement could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.
