[REVERSE OF NOTE]

1. INDENTURE. (a) This Note is one of a duly authorized issue of senior debt securities of the Company (hereinafter called the “Notes”), all issued or to be issued under and pursuant to the Indenture, dated as of June 5, 2012 (the “Indenture”), between the Company and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), as Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. The Company has appointed the Trustee as the paying agent (the “Paying Agent,” which term includes any additional or successor Paying Agent appointed by the Company) with respect to the Notes. To the extent not inconsistent herewith, the terms of the Indenture are hereby incorporated by reference herein. This Note is one of the series designated on the face hereof initially limited in aggregate principal amount to $500,000,000; provided that the Company may from time to time, without notice to or the consent of the Holders of the Notes, create and issue additional Notes (the “Additional Notes”) having the same terms and ranking equally and ratably with the existing Notes, in all respects and with the same CUSIP number as the existing Notes, or in all respects except for any differences in the issue price and the payment of interest accruing prior to the issue date of the Additional Notes or for the first payment of interest following the issue date of such Additional Notes. Any Additional Notes will be consolidated and form a single series with the existing Notes and shall have the same terms as to status, redemption and otherwise as such Notes. Any Additional Notes may be issued pursuant to authorization provided by a resolution of the Board of Directors of the Company, a supplement to the Indenture, or under an Officers’ Certificate pursuant to the Indenture. No Additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the existing Notes. If such Additional Notes are not fungible for purposes of U.S. federal income tax purposes, such Additional Notes shall have a different CUSIP number. (b) All capitalized terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

2. AMENDMENTS AND WAIVERS. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes of any series and the Trustee with the consent of the Holders of a majority in aggregate principal amount of all of the Notes of each applicable series then Outstanding affected by such amendment or modification (treated as a single class). The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of all of the Notes of each applicable series then Outstanding affected thereby (treated as a single class) to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. For the avoidance of doubt, with respect to any series of Notes, the consent or waiver, as the case may be, of Holders of Notes of such series required or permitted under the Indenture, as the case may be, if the Company so determines, may also be obtained from the Holders of a majority in principal amount of the Notes of that series.

3. OBLIGATION TO PAY PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company or any other obligor on the Notes, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note in the manner, at the respective times, at the rate, and in the coin or currency herein prescribed.

4. OPTIONAL REDEMPTION. Prior to July 1, 2029 (one month prior to this Note’s maturity date (the “Par Call Date”)), the Company may redeem this Note at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of:

(1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming this Note matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of this Note to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Company may redeem this Note, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of this Note being redeemed plus accrued and unpaid interest thereon to the redemption date.

For purposes of Section 4 of this Note, the following definitions are applicable:

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC’s (or any successor depositary’s) procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed.

Notice of any redemption of Notes may, at the Company’s discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness or an acquisition or other strategic transaction involving a change of control in the Company or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the Business Day immediately preceding the relevant redemption date.

The Company shall notify holders of any such rescission as soon as practicable after the Company determines that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent, in each case subject to policies and procedures of DTC (or any successor depositary). In any event, the Company shall provide written notice to the Trustee prior to the close of business on the Business Day prior to the relevant redemption date if any such redemption has been rescinded or delayed, and upon receipt of such notice the Trustee, at the expense of the Company, shall provide such notice to each holder of the Notes in the same manner in which the notice of redemption was given. Once notice of redemption is mailed or sent, subject to the satisfaction of any conditions precedent provided in the notice of redemption, the Notes called for redemption will become due and payable on the redemption date and at the applicable redemption price.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed and the CUSIP number of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of this Note shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on this Note or the portion of this Note called for redemption.

5. RESTRICTIONS ON SECURED DEBT. The Company covenants and agrees for the benefit of the Holder of this Note that for so long as this Note is outstanding, the Company will not, and the Company will not permit any Restricted Subsidiary to, incur, issue, assume or guarantee any notes, bonds, debentures or other similar evidences of indebtedness for money borrowed (“Debt”), secured by pledge of, or mortgage or lien on, any Principal Property (as defined below) of the Company or any Restricted Subsidiary, or any shares of stock of or Debt of any Restricted Subsidiary (such pledges, mortgages and liens being called “Mortgage” or “Mortgages” and such debt secured by such Mortgages being called “Secured Debt”), without effectively providing that this Note (together with, if the Company shall so determine, any other indebtedness of the Company or such Restricted Subsidiary then existing or thereafter created which is not subordinate to this Note) shall be secured equally and ratably with (or prior to) such Secured Debt, so long as such Secured Debt shall be so secured, unless after giving effect thereto, the aggregate amount of all such Secured Debt plus all Attributable Debt of the Company and the Company’s Restricted Subsidiaries in respect of any Sale and Leaseback Transaction (as defined below) would not exceed 15% of Consolidated Net Tangible Assets calculated as of the date of the creation or incurrence of such Secured Debt; provided, however, that this restriction shall not apply to, and there shall be excluded from Secured Debt in any computation under such restriction, indebtedness secured by:

6. LIMITATIONS ON SALE LEASEBACK TRANSACTIONS. The Company will not, and the Company will not permit any Restricted Subsidiary to, enter into any arrangement with any bank, insurance company or other lender or investor (not including the Company or any Restricted Subsidiary) or to which any such lender or investor is a party, providing for the leasing by the Company or a Restricted Subsidiary for a period, including renewals, in excess of three years of any Principal Property the ownership of which has been or is to be sold or transferred, more than 180 days after the completion of construction and commencement of full operation thereof, by the Company or such Restricted Subsidiary to such lender or investor or to any Person to whom funds have been or are to be advanced by such lender or investor on the security of such Principal Property (referred to as a “Sale and Leaseback Transaction”) unless either:

No retirement referred to in clause (b) of Section 6 of this Note may be effected by payment.

“Principal Property” means any single parcel of real estate, any single manufacturing plant or any single warehouse owned or leased in connection with a Sale and Leaseback Transaction by the Company or any Subsidiary which is located within the U.S. and the net book value of which on the date as of which the determination is being made exceeds 1% of Consolidated Net Tangible Assets, other than any such manufacturing plant or warehouse or portion thereof (1) which is a pollution control or other facility financed by obligations issued by a state or local government unit and described in Sections 141(a), 142(a)(5), 142(a)(6), 142(a)(10) or 144(a) of the Internal Revenue Code (or their successor provisions) or by any other obligations the interest of which is excluded under Section 103 of the Internal Revenue Code (or its successor provision), or (2) which, in the opinion of the Company’s board of directors is not of material importance to the total business conducted by the Company and its Subsidiaries taken as a whole.

7. REPURCHASE AT OPTION OF HOLDER. Upon the occurrence of a Change of Control Triggering Event, and subject to certain conditions set forth in the Indenture, the Company will be required to offer to purchase all of the Outstanding Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase.

8. CERTAIN COVENANTS. The Indenture restricts, among other things, the ability of the Company to merge or consolidate with, or transfer all or substantially all of its assets to, other companies. These covenants, as well as the covenants set forth in this Note, are subject to the defeasance procedures outlined in the Indenture.

9. EFFECT OF EVENT OF DEFAULT. If an Event of Default shall have occurred and be continuing under the Indenture, the principal hereof may be declared immediately due and payable in the manner, with the effect and subject to the conditions provided in the Indenture.

10. DEFEASANCE. The Indenture contains provisions for legal defeasance and covenant defeasance at any time of the Indebtedness on this Note upon compliance by the Company with certain conditions set forth therein.

12. HOLDER AS OWNER. Prior to the due presentment of this Note for registration of transfer, the Company, the Trustee, any Registrar and any Paying Agent of the Company or the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions on the face hereof, interest hereon, and for all other purposes, and none of the Company, the Trustee, any Registrar or any Paying Agent of the Company or the Trustee shall be affected by any notice to the contrary.

13. NO LIABILITY OF CERTAIN PERSONS. No recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any Indebtedness represented thereby, shall be had against any past, present or future incorporator, shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company, or any successor corporation, under any constitution, statute or rule of law or by the enforcement of any assessment or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.
