Notice of any redemption will be mailed (or, in the case of notes held in book-entry form,
be transmitted electronically in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each registered holder of the notes to be redeemed, except that redemption notices may be
delivered more than 60 days prior to a redemption if the notice is issued in connection with a legal or covenant defeasance of the notes or a satisfaction and discharge of the Indenture as described under “Description of Debt
Securities—Discharge, Defeasance and Covenant Defeasance” in the accompanying prospectus.

condition, and if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was sent, including
