(d) Maturity: The entire outstanding principal of the Notes shall be payable in a single installment on March 17, 2017 (the “Stated Maturity”).

(e) Interest:

(i) Interest shall accrue on the Notes at a floating rate equal to the three-month U.S. dollar LIBOR (as defined below) for the applicable Interest Reset Period or Initial Interest Period (each as defined below) plus 2.360% until all required amounts due in respect of the Notes have been paid. All interest shall be paid by the Company to the Trustee and distributed by the Trustee in accordance with this Indenture quarterly in arrears on March 17, June 17, September 17 and December 17 of each year during which any portion of the Notes shall be Outstanding (each, an “Interest Payment Date”), commencing on June 17, 2014, and will initially accrue from and including the date of issuance and thereafter from the last Interest Payment Date to which interest has been paid. Interest shall be paid to the Person in whose name a Note is registered at the close of business on the preceding Regular Record Date (which shall mean, with respect to any payment to be made on an Interest Payment Date, the Business Day preceding the relevant Interest Payment Date). Interest accrued with respect to the Notes shall be calculated on the basis of the actual number of days in the relevant interest period divided by 360. As provided in the Original Indenture, (i) payment of principal and interest and other amounts on the Notes will be made at the Corporate Trust Office of the Trustee in New York City, or such other paying agent office in the United States as the Company appoints, in the form provided for in Section 10.08 of the Original Indenture, (ii) all such

payments to the Trustee shall be made by the Company by depositing immediately available funds in U.S. Dollars prior to 3:00 p.m., New York City time, one Business Day prior to the relevant Interest Payment Date to the Payment Account and (iii) so long as any of the Notes remain Outstanding, the Company shall maintain a paying agent in New York City.

(ii) The interest rate on the Notes shall be reset quarterly on March 17, June 17, September 17 and December 17 of each year, as applicable, commencing June 17, 2014 (each, an “Interest Reset Date”). The “Initial Interest Period” will be the period from and including the original issue date to but excluding the initial Interest Reset Date. Thereafter, each “Interest Reset Period” will be the period from and including an Interest Reset Date to but excluding the immediately succeeding Interest Reset Date; provided that the final Interest Reset Period for the Notes will be the period from and including the Interest Reset Date immediately preceding the Maturity date of such Notes to but excluding the Maturity date. The interest rate in effect on each day will be (i) if that day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding such Interest Reset Date or (ii) if that day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date or the original issue date, as the case may be. The interest rate applicable to each Interest Reset Period commencing on the related Interest Reset Date, or the original issue date in the case of the Initial Interest Period, will be the rate determined as of the applicable Interest Determination Date. The “Interest Determination Date” will be the second LIBOR Business Day immediately preceding the original issue date, in the case of the initial Interest Reset Period, or thereafter the applicable Interest Reset Date.

(iii) Three-month LIBOR shall be determined by the Calculation Agent as of the applicable Interest Determination Date in accordance with the following provisions:

(A) LIBOR is the rate (expressed as a percentage per annum) for deposits in U.S. dollars having a maturity of three months commencing on the related interest reset date that appears on Bloomberg L.P.’s page “BBAM” as of 11:00 a.m., London time, on the applicable Interest Determination Date. “Bloomberg L.P.’s page “BBAM” means the display that appears on Bloomberg L.P.’s page “BBAM” or any page as may replace such page on such service (or any successor service) for the purpose of displaying London interbank offered rates of major banks for U.S. dollars. If no rate appears on Bloomberg L.P.’s page “BBAM” , LIBOR for such Interest Determination Date will be determined in accordance with the provisions of Section 2.01(e)(iii)(B) below.

(B) With respect to an Interest Determination Date on which no rate appears on Bloomberg L.P.’s page “BBAM”, the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market (which may include affiliates of the underwriters), as selected by the Calculation Agent (after consultation with the Company), to provide its offered quotation (expressed as a percentage per annum) for deposits in U.S. dollars for the period of three months, commencing on the related Interest Reset

Date, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two quotations are provided, then LIBOR on such Interest Determination Date will be the arithmetic mean of those quotations. If fewer than two quotations are provided, then LIBOR on such Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in the City of New York, on the Interest Determination Date date by three major banks in The City of New York (which may include affiliates of the underwriters) selected by the Calculation Agent (after consultation with the Company) for loans in U.S. dollars to leading European banks, for a period of three months, commencing on the related Interest Reset Date, and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two such rates are so provided, LIBOR on the Interest Determination Date date will be the arithmetic mean of such rates. If fewer than two such rates are so provided, LIBOR on the Interest Determination Date will be LIBOR in effect with respect to the immediately preceding Interest Determination Date.

(iv) All percentages resulting from any calculation of any interest rate for the Notes will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

(v) Promptly upon such determination, the Calculation Agent shall notify the Company and the Trustee (if the Calculation Agent is not the Trustee) of the interest rate for the new Interest Reset Period. Upon request of a Holder of the Notes, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Reset Period. All calculations made by the Calculation Agent for the purposes of calculating interest on the Notes shall be conclusive and binding on the Holder and the Company, absent manifest errors.

(vii) For purposes of Section 2.01(e) of this Eighteenth Supplemental Indenture, the term “Calculation Agent” means The Bank of New York Mellon, or its successor appointed by the Company. All of the benefits, protections, privileges, immunities, indemnities, and rights under the Indenture that apply to the Trustee also apply to The Bank of New York Mellon, in its individual capacity and in its capacity as Calculation Agent hereunder.

(f) Default Rate: Upon the occurrence and during the continuation of an Event of Default, (i) interest on the outstanding principal amount of the Notes shall accrue on the Notes at a rate equal to 0.5% per annum above the interest rate on the Notes at that time (the “Default Rate”) and (ii) to the fullest extent permitted by law, interest

shall accrue on the amount of any interest, fee, Additional Amounts, or other amount payable under the Indenture and the Notes that is not paid when due, from the date such amount was due until such amount shall be paid in full, excluding the date of such payment, at the Default Rate.

The Company agrees that the Payment Account shall be maintained in the name of the Trustee and under its sole dominion and control (acting on behalf of the Holders of the Notes) and used solely to make payments of principal, interest and other amounts from time to time due and owing on, or with respect to, the Notes. No funds contained in the Payment Account shall be used for any other purpose or in any manner not expressly provided for herein nor shall the Company or any other Person have an interest therein or amounts on deposit therein.
