“Subject to the provisions of Section 4.14(d) hereof, at least two Business Days but not more than 60 days before a Redemption Date, the Issuers will send, or cause to be sent, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof, respectively.

The notice of redemption will identify the Notes to be redeemed and will state:

(1) the Redemption Date;

(2) the redemption price, if then determinable, and, if not, then a method for determination;

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note;

(4) the name and address of the Paying Agent;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(9) any conditions precedent with respect to such redemption.

At the Issuers’ request, the Trustee shall give the notice of redemption in the Issuers’ names and at their expense; provided, however, that the Issuers have delivered to the Trustee, at least five Business Days prior to the date of giving such notice (unless a shorter notice period shall be satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.
