Reference to the Indenture is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the Securityholders of the Securities. This Security is one of a series designated as the “Floating Rate Notes Due 2019” of the Company (hereinafter called the “Notes”), issued under the Indenture. Each Securityholder, by accepting a Note, agrees to be bound by all terms and provisions of the Indenture, as amended from time to time, applicable to the Notes.

The Notes issued under the Indenture are senior unsecured obligations of the Company and will mature on November 29, 2019. The Notes rank on parity with all other existing and future senior unsecured obligations of the Company from time to time outstanding.

The Notes are not redeemable.

The Notes are not entitled to any sinking fund, and no Securityholder of the Notes may require the Company to make any mandatory redemption of the Notes or purchase or make an offer to purchase the Notes.

The Notes are subject to satisfaction and discharge pursuant to Article XI of the Base Indenture.

In case an Event of Default shall have occurred and is continuing with respect to the Notes, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture provides that in certain circumstances such declaration and its consequences may be waived by the Securityholders of not less than a majority in aggregate principal amount of the Notes then Outstanding. However, any such consent or waiver by the Securityholder shall not affect any subsequent default or impair any right consequent thereon.

The Base Indenture permits the Company and the Trustee, without the consent of the Securityholders of the Notes for certain situations and with the consent of not less than a majority of the Securityholders in aggregate principal amount of the Outstanding Notes of each series affected by such supplemental indenture in other situations, to execute supplemental indentures adding to, modifying, or changing various provisions of, the Base Indenture; provided that no such supplemental indenture, without the consent of the Securityholder of each Outstanding Note affected thereby, shall (i) change the maturity date of any Securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of

interest thereon, or reduce any premium payable upon the redemption thereof, (ii) reduce the amount of principal of an Original Issue Discount Security or any other Security payable upon acceleration of maturity, (iii) change the currency in which any Security or any premium or interest is payable, (iv) impair the right to receive payment of principal of and interest on any Security (whether upon redemption, repurchase, maturity, or otherwise) or payment or delivery of any amounts due upon conversion of Securities of any series that are convertible into shares of common stock or other securities on or after the due dates or to institute suit for the enforcement of any payment on or with respect to any Security, (v) adversely change the right to convert or exchange, including decreasing the conversion rate or increasing the conversion price of, that Security (if applicable), (vi) if the Securities are secured, change the terms and conditions pursuant to which the Securities are secured in a manner adverse to the holders of the Securities, (vii) reduce the percentage in principal amount of outstanding Securities of any series, the consent of whose holders is required for modification or amendment of the Indenture or for waiver of compliance with any provision of the Indenture, (viii) reduce the requirements contained in the Indenture for a quorum for a meeting or for voting, (ix) change any obligations of the Company to maintain an office or agency in the places and for the purposes required by the Indenture, (x) in the case such series of Securities is subordinated to other indebtedness of the Company pursuant to a supplement indenture, modify the subordination provisions in such supplemental indenture in a manner adverse to the holders of such Securities, or (xi) modify Sections 9.1 or 9.2 of the Base Indenture.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of or interest on this Security at the respective times and at the rate herein prescribed.

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 and in integral multiples of $1,000 in excess thereof. A Securityholder may exchange the Notes for a like aggregate principal amount of Notes of other authorized denominations in the manner and subject to the limitations provided in the Indenture.

Upon due presentment for registration of transfer of the Notes at the office or agency for said purpose of the Company, a new Note or Notes of authorized denominations, for a like aggregate principal amount, will be issued to the transferee as provided in the Indenture. No service charge shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

Prior to due presentation of this Security for registration of transfer, the Company, the Trustee, and any agent of the Company or the Trustee, may deem and treat the Securityholder hereof as the owner of this Security (whether or not any payment with respect to this Security shall be overdue), for the purpose of receiving payment of principal of and (subject to the provisions of the Indenture) interest hereon and for all other purposes whatsoever, whether or not any payment with respect to this Security shall be overdue, and neither the Company, nor the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.
