"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term ("Remaining Life") of the Notes to be redeemed 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 such Notes. "Comparable Treasury Price" means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. "Independent Investment Banker" means one of the Reference Treasury Dealers that the Company appoints to act as the Independent Investment Banker from time to time. "Reference Treasury Dealer" means Banc of America Securities LLC and J.P. Morgan Securities Inc. and their respective successors, and two other firms that are primary U.S. Government securities dealers (each a "Primary Treasury Dealer") which the Company specifies from time to time; provided, however, that if any of them ceases to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, 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 Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.
