| Book-entry Issuance, Settlement and Clearance | We will issue the notes solely in book-entry form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will be represented by one or more global securities deposited with DTC and registered in the name 
 of Cede & Co., as nominee of DTC. You will hold beneficial interests in the notes through DTC, and DTC and its direct and indirect participants (including Euroclear and Clearstream, Luxembourg) will record your beneficial interest on their       
 books. We will not issue certificated notes except in limited circumstances that we explain under “Legal Ownership” in the attached prospectus. Settlement of the notes will occur through DTC in                                                     
 same-day funds. For information on DTC’s book-entry system, see “Clearance and Settlement” in the attached prospectus.                                                                                                                                |

| Additional Notes | We may, at our option, at any time and without giving notice to or seeking the consent of the then-existing noteholders issue additional notes in one or more transactions subsequent to the date of this prospectus supplement with terms (other  
 than the issuance date, the date upon which interest begins to accrue and, in some cases, the first interest payment date) identical to the notes offered hereby. These additional notes will be deemed to be part of the same series as the notes 
 offered hereby and will provide the holders of these additional notes the right to vote together with holders of the notes offered hereby. Such additional notes will be issued with no more than de minimis original issue discount for U.S.      
 federal income tax purposes or be part of a qualified reopening for U.S. federal income tax purposes.                                                                                                                                              |
