In connection with such optional redemption the following defined terms apply:
	“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.
	“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.

Incorporated, Credit Suisse Securities (USA) LLC, Barclays Capital Inc., BNP Paribas Securities Corp., Citigroup Global Markets Inc., Credit Agricole Securities (USA) Inc., HSBC Securities (USA) Inc. and their respective successors and one other nationally recognized investment banking firm that is a Primary Treasury Dealer specified from time to time by the Company, provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding that redemption date.

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the remaining

	scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption, provided, however, that, if that redemption date is not an interest payment date with respect to such Notes, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to that redemption date.
	Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the Notes to be redeemed. On and after any redemption date, interest will cease to accrue on the Notes or any portion thereof called for redemption. On or before any redemption date, the Company shall deposit with a paying agent (or the Trustee) money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all the Notes are to be redeemed, the Notes to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate. The redemption price shall be calculated by the Independent Investment Banker and the Company and the Trustee and any paying agent for the Notes shall be entitled to rely on such calculation.
Further Issues:	The Company may from time to time without the consent of the holders of the Notes create and issue further notes having the same terms and conditions as the notes so that the further issue is consolidated and forms a single series with such notes, provided that such further issue constitutes a “qualified reopening” for U.S. federal income tax purposes or such further notes are issued with not more than a de minimis amount of original issue discount for U.S. federal income tax purposes.
