Certificated Debt Securities

We will issue debt securities to you in certificated
registered form only if:

| · | Clearstream or Euroclear is no longer willing or able to discharge its responsibilities properly, and 
 neither the trustee nor we have appointed a qualified successor within 90 days; or                    |

| · | we, at our option, notify the trustee that we elect to cause the issuance of certificated debt securities; 
 or                                                                                                         |

| · | certain other events provided in the indenture should occur, including the occurrence and continuance 
 of an event of default with respect to the debt securities.                                           |

If any of these three events occurs, the trustee
will reissue the debt securities in fully certificated registered form and will recognize the registered holders of the certificated debt
securities as holders under the indenture.

In the event that we issue certificated securities
under the limited circumstances described above, then holders of certificated securities may transfer their debt securities in whole or
in part upon the surrender of the certificate to be transferred, together with a completed and executed assignment form endorsed on the
definitive debt security, at the offices of the transfer agent in New York City. Copies of this assignment form may be obtained at the
offices of the transfer agent in New York City. Each time that we transfer or exchange a new debt security in certificated form for another
debt security in certificated form, and after the transfer agent receives a properly completed assignment form, we will make available
for delivery the new definitive debt security at the offices of the transfer agent in New York City. Alternatively, at the option of the
person requesting the transfer or exchange, we will mail, at that person’s risk, the new definitive debt security to the address
of that person that is specified in the assignment form. In addition, if we issue debt securities in certificated form, then we will make
payments interest on and any other amounts payable under the debt securities to holders in whose names the debt securities in certificated
form are registered at the close of business on the record date for these payments. If the debt securities are issued in certificated
form, we will make payments of principal and any redemption payments against the surrender of these cert
