Optional Redemption:

The notes are redeemable, as a whole or in part, at our option, at any time or from time to time, upon notice mailed to the registered address of each holder of notes at least 30 days but not more than 60 days prior to the redemption date. The “make-whole premium” redemption price will be equal to the greater of (1) 100% of the principal amount of the notes to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) on such notes discounted to the date of redemption, on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the applicable Treasury Rate (as defined below) plus 50 basis points. Accrued interest will be paid to, but excluding, the redemption date.


  “Treasury Rate” means, with respect to any redemption date, the rate per year 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 (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for that redemption date.


  “Comparable Treasury Issue” means the United States Treasury security selected by a Reference Treasury Dealer (as defined below) as having an actual or interpolated maturity comparable to the remaining term of the notes called for redemption, 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 notes called for redemption.


  “Comparable Treasury Price” means, with respect to any redemption date, the average, as determined by us, of the Reference Treasury Dealer Quotations (as defined below) for that redemption date.


  “Reference Treasury Dealer” means Wells Fargo Securities, LLC and Barclays Capital Inc. and one other U.S. Government securities dealer selected by us, and each of their respective successors.


  “Reference Treasury Dealer Quotations” means, on any redemption date, the average, as determined by us, 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 us by each 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 the remaining scheduled payments of principal of and interest on the notes called for redemption that would be due after the related redemption date but for that redemption. If that redemption date is not an interest payment date with respect to the notes called for redemption, the amount of the next succeeding scheduled interest payment on such notes will be reduced by the amount of interest accrued to such redemption date.

  We will prepare and mail a notice of redemption to each holder of notes to be redeemed by first-class mail at least 30 and not more than 60 days prior to the date fixed for redemption. On and after a redemption date, interest will cease to accrue on the notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before a redemption date, we will 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 that date. If less than all of the notes are to be redeemed, the notes to be redeemed shall be selected by the trustee pro rata or by lot or by a method the trustee deems to be fair and appropriate.
