          “ Comparable Treasury Price ” means, with respect to any Redemption Date, as determined by the Company (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (ii) 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 appointed by the Trustee after consultation with the Company.

          “ 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 3:30 p.m., New York time on the third Business Day preceding such Redemption Date.

          “ Reference Treasury Dealers ” means J.P. Morgan Securities Inc., Banc of America Securities LLC and the Primary Treasury Dealer selected by Wachovia Capital Markets, LLC and their affiliates which are primary U.S. Government securities dealers, and their respective successors; provided, however, that if any of J.P.

          “ Treasury Rate ” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated yield (on a day count basis) 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 such Redemption Date.

          Unless the Company defaults in the payment of the Redemption Price and accrued interest, on and after the Redemption Date interest will cease to accrue on the Notes thereof called for redemption. In the event that any Redemption Date is not a Business Day, the Company will pay the Redemption Price on the next Business Day without any interest or other payment due to the delay.

     2.09 Change of Control Repurchase Event . If a Change of Control Repurchase Event (as defined below) occurs with respect to a series of Notes, unless the Company has exercised its right to redeem the Notes pursuant to Section 2.08 hereof, the Company will make an offer to each Holder of such Notes to repurchase all or any part (in amounts of $2,000 and integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of repurchase (the “ Change of Control Payment ”). Within 30 days following the consummation of any Change of Control Repurchase Event or, at the Company’s option, prior to the consummation of any Change of Control (as defined below), but after the public announcement of an impending Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase such Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “ Change of Control Payment Date ”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

          The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the “ Exchange Act ”), and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of Notes of such series as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

          On the Change of Control Repurchase Payment Date, the Company will, to the extent lawful: (i) accept for payment all Notes or portions of Notes (in amounts of $2,000 and integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Company’s Change of Control Offer; (ii) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered and not withdrawn; and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company.

          The Paying Agent will promptly mail to each Holder of properly tendered Notes the repurchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided , that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 above that amount.

          The Company will not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control Offer made by the Company, and such third party purchases all Notes properly tendered and not withdrawn under its Change of Control Offer. In the event that such third party terminates or defaults on its Change of Control Offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default by such third party as though it were the date of the Change of Control Repurchase Event.

nomination, election or appointment (either by a specific vote or by approval of the Company’s proxy statement in which such member was named as a nominee for election as a director).

          “ Investment Grade ” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Company.

          “ Moody’s ” means Moody’s Investors Service Inc.

          “ Rating Agency ” means (1) each of Moody’s and S&P; and (2) if any of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company as a replacement agency for Moody’s or S&P, as the case may be, and that is reasonably acceptable to the Trustee.
