“Trustee”), to the Indenture, dated as of August 29, 2012 (the “Original Indenture”, and as supplemented by the Amended and Restated Twenty-Fifth Supplemental Indenture and any further supplements thereto with
respect to the Notes, the “Indenture”), by and among the Issuer and the Trustee. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of interests, benefits, obligations and duties
thereunder of the Issuer, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. All capitalized terms used in this Note which are defined in the Indenture and not otherwise defined herein

 As provided for in the
Indenture, the Issuer promises to pay interest on the outstanding principal amount hereof, from the Closing Date, semi-annually in arrears on February 1 and August 1 of each year, (each such date, an “Interest Payment
Date”), commencing August 1, 2019 at a rate equal to 5.750% per annum, and will initially accrue from the date of issuance and thereafter from the last Interest Payment Date to which interest has been paid. Interest payable, and
punctually paid or duly provided for, on this Note on any Interest Payment Date will, as provided in the Indenture, be paid in U.S. dollars to the Person in whose name this Note (or one or more predecessor Notes) is registered at the close of

 Payment of the principal of and interest on this Note will be payable by wire transfer to a
U.S. dollar account maintained by the Holder of this Note as reflected in the Security Register of the Trustee. In the event the date for any payment of the principal of or interest on any Note is not a Business Day, then payment will be made on the
next Business Day with the same force and effect as if made on the nominal date of any such date for such payment and no additional interest will accrue on such payment as a result of such payment being made on the next succeeding Business Day.
Interest shall accrue on the Notes at the rate of 5.750% per annum until all required amounts due in respect of the Notes have been paid. Interest accrued with respect to this Note shall be calculated based on a
360-day year of twelve 30-day months. 
 The Notes are

 This Note does not purport to summarize the
Indenture, and reference is made to the Indenture for information with respect to the respective rights, limitations of interests, benefits, obligations and duties thereunder of the Issuer, the Trustee and the Holders. 

If an Event of Default shall occur and be continuing, the outstanding principal amount of all the Notes may become or may be declared due and
payable in the manner and with the effect provided in the Indenture. 
 Modifications of the Indenture may be made by the Issuer and the
Trustee only to the extent and in the circumstances permitted by the Indenture.
