ARTICLE II

GENERAL TERMS AND CONDITIONS OF THE NOTES

SECTION 2.01.Designation and Principal Amount. The Notes are hereby authorized and are designated the 5.875% Senior Notes due 2023, initially limited in aggregate principal amount to $500,000,000. The Notes issued on the date hereof pursuant to the terms of this Indenture shall be in an aggregate principal amount of $500,000,000, which amount shall be set forth in the Company Order for the authentication and delivery of the Notes pursuant to Section 3.03 of the Base Indenture. In addition, the Company may issue, from time to time in accordance with the provisions of this Indenture, additional Notes having the same terms and

conditions as the Notes issued on the date hereof in all respects (except for the payment of interest accruing prior to the issue date of such additional Notes), so that such additional Notes shall be consolidated and form a single series with the Notes issued on the date hereof and shall be governed by the terms of the Indenture.

SECTION 2.02.Maturity. The principal amount of the Notes shall be due and payable on August 15, 2023.

SECTION 2.03.Form and Payment.

The Notes shall be issued in substantially the form set forth on Exhibit A hereto and shall have the terms set forth in such form and shall initially be Global Securities for purposes of the Base Indenture. The Notes shall be issued in fully registered
book-entry form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Depositary in respect of the Notes represented by Global Securities shall be The Depository Trust Company. The Global Securities representing the Notes shall be deposited with, or on behalf of, the Depositary and shall be registered in the name of its nominee, Cede & Co. Except as otherwise set forth in Section 3.05 of the Base Indenture, the Global Securities may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee.

The Trustee shall act as Paying Agent for the Notes. The Company may choose to pay interest by mailing checks or making wire or other electronic funds transfers. All money paid by the Company to any Paying Agent that remains unclaimed at the end of two years after the amount is due to Holders shall be repaid to the Company, subject to any applicable abandoned property laws. After such two-year period, Holders may look only to the Company for payment and not to the Trustee, any other Paying Agent or anyone else. The Company may also arrange for additional payment offices, and may cancel or change these offices, including any use of the Trustee’s Corporate Trust Office. The Company may appoint and change the Paying Agent without prior notice to the Holders.

SECTION 2.04.Interest. Interest on the Notes shall accrue at the rate of 5.875% per annum, subject to adjustment pursuant to Section 2.05. Interest on the Notes shall accrue from July 12, 2013 or the most recent Interest Payment Date to which interest was paid or duly provided for. Interest on the Notes shall be payable semiannually in arrears on February 15 and August 15, commencing on February 15, 2014 (each an “Interest Payment Date”), to the Holders in whose names the Notes are registered at the close of business on the February 1 and August 1, as the case may be, immediately preceding such Interest Payment Date (each a “Regular Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 2.05.Payment of Additional Interst Based on Rating Events. The interest rate payable on the Notes will be subject to adjustments from time to time if either Moody’s or S&P or, in either case, any Substitute Rating Agency thereof downgrades (or subsequently upgrades) the debt rating assigned to the Notes, in the manner described below. It shall be the obligation of the Company to promptly notify the Trustee of any change in interest

rate payable on the Notes pursuant to this Section 2.05. Such notice shall be given by delivery to the Trustee of an Officers’ Certificate, on which the Trustee may conclusively rely. The Officers’ Certificate shall state that the interest rate borne by the Notes has been adjusted in accordance with this Section 2.05 and shall set forth (a) the amount of the related increase or decrease of interest rate, (b) the new interest rate borne by the Notes, and (c) the amount of interest that shall be due and payable on the next succeeding Interest Payment Date. The Trustee shall have no obligation (i) to monitor the debt rating assigned to the Notes, (ii) to determine whether any change to the interest rate payable on the Notes is required by this Section 2.05, or (iii) to determine the interest rates applicable to the Notes.

If the rating from Moody’s (or any Substitute Rating Agency thereof) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase such that it will equal the interest rate payable on the Notes on the Issue Date of the Notes plus the percentage set forth opposite the applicable rating from the table below:


Moody’s Rating*	Percentage
Ba1		0.25	%
Ba2		0.50	%
Ba3		0.75	%
B1 or below		1.00	%

*	Including the equivalent ratings of any Substitute Rating Agency.

If the rating from S&P (or any Substitute Rating Agency thereof) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase such that it will equal the interest rate payable on the Notes on the Issue Date of the Notes plus the percentage set forth opposite the applicable rating from the table below:


S&P’s Rating*	Percentage
BB+		0.25	%
BB		0.50	%
BB-		0.75	%
B+ or below		1.00	%

*	Including the equivalent ratings of any Substitute Rating Agency.

If at any time the interest rate on the Notes has been adjusted upward and either Moody’s or S&P (or, in either case, a Substitute Rating Agency thereof), as the case may be, subsequently increases its rating of the Notes to any of the threshold ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the Notes equals the interest rate payable on the Notes on the Issue Date of the Notes plus the percentages set forth opposite the applicable ratings from the tables above in effect immediately following the increase. If Moody’s (or any Substitute Rating Agency thereof) subsequently increases its rating of the Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, and S&P (or any Substitute Rating Agency thereof) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Notes will be decreased to the interest rate payable on the Notes on the Issue Date. In addition, the interest rates on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by either or both Rating Agencies) if the Notes become rated

A3 and A- (or the equivalent of either such rating, in the case of a Substitute Rating Agency) or higher by Moody’s and S&P (or, in either case, a Substitute Rating Agency thereof), respectively (or one of these ratings if the Notes are only rated by one Rating Agency).

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s or S&P (or, in either case, a Substitute Rating Agency thereof), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Notes be reduced to below the interest rate payable on the Notes on the Issue Date or (2) the total increase in the interest rate on the Notes exceed 2.00% above the interest rate payable on the Notes on the Issue Date.

No adjustments in the interest rate of the Notes shall be made solely as a result of a Rating Agency ceasing to provide a rating of the Notes. If at any time fewer than two Rating Agencies provide a rating of the Notes for a reason beyond the Company’s control, the Company will use its commercially reasonable efforts to obtain a rating of such Notes from a Substitute Rating Agency, to the extent one exists, and if a Substitute Rating Agency exists, for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative rating scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an Independent Investment Banker appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate on the Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate payable on the Notes on the Issue Date plus the appropriate percentage, if any, set forth opposite the rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other Rating Agency). For so long as only one Rating Agency provides a rating of the Notes, any subsequent increase or decrease in the interest rate of such Notes necessitated by a reduction or increase in the rating by the Rating Agency providing the rating shall be twice the percentage set forth in the applicable table above. For so long as none of Moody’s, S&P or a Substitute Rating Agency provides a rating of the Notes, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Notes on the Issue Date.

Any interest rate increase or decrease described above will take effect from the first day of the interest period during which a rating change requires an adjustment in the interest rate. If Moody’s or S&P (or, in either case, a Substitute Rating Agency thereof) changes its rating of the Notes more than once during any particular interest period, the last change by such Rating Agency will control for purposes of any interest rate increase or decrease with respect to the Notes pursuant to this Section 2.05 relating to such Rating Agency’s action.

If the interest rate payable on the Notes is increased as described in this Section 2.05 the term “interest,” as used with respect to the Notes, will be deemed to include any such additional interest unless the context otherwise requires.

SECTION 2.06.No Sinking Fund. The provisions of Article XII of the Base Indenture shall not be applicable to the Notes.

ARTICLE III

ADDITIONAL COVENANTS

In addition to the covenants set forth in Article X of the Base Indenture, the Company also covenants and agrees for the benefit of Notes, but not Securities of any other series, as follows:

SECTION 3.01.Limitation on Liens. The Company shall not, and will not permit any of its Domestic Subsidiaries, directly or indirectly, to issue, assume or guarantee any Debt if that Debt is secured by any Lien upon any Principal Property (or portion thereof) of the Company or of any Domestic Subsidiary of the Company or any shares of stock or Debt of any of its Domestic Subsidiaries, whether owned on June 1, 2009 or thereafter acquired, without effectively securing the Notes equally and ratably with that Debt, so long as such Debt is so secured. The foregoing restriction does not apply to:

(i) Liens on any property acquired, constructed or improved by the Company or any Domestic Subsidiary of the Company after June 1, 2009, which are created or assumed contemporaneously with or within three years after its acquisition, or completion of construction or improvement (or within six months thereafter pursuant to a firm commitment for financing arrangements entered into within that three-year period) to secure or provide for the payment of the Purchase Price or cost thereof, or Liens existing on any property at the time of its acquisition;

(ii) Liens existing on any property, shares of stock or indebtedness acquired from a Person merged with or into the Company or a Domestic Subsidiary of the Company after June 1, 2009;

(iii) with respect to any corporation that becomes a Domestic Subsidiary of the Company after June 1, 2009, Liens on property of, or shares of stock or indebtedness issued by, any such corporation existing at the time it becomes a Domestic Subsidiary and not incurred in connection with or in anticipation of such corporation becoming a Domestic Subsidiary;

(iv) Liens to secure Debt of a Domestic Subsidiary owed to the Company or Debt of one of the Domestic Subsidiaries of the Company owed to another Domestic Subsidiary of the Company;

(v) Liens in favor of governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or statute;

(vi) any Lien existing on June 1, 2009; or

(vii) Liens for the sole purpose of extending, renewing or replacing Debt, in whole or in part, secured by any Lien referred to in the foregoing clauses (i) to (vi),

inclusive;provided,however, that the principal amount of Debt secured by that Lien shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to the property that secured the Lien so extended, renewed or replaced (plus improvements on such property).

The limitation on Liens described in this Section 3.01 shall not apply to the issuance, assumption or guarantee by the Company or any Domestic Subsidiary of the Company of Debt secured by a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount which, together with all other Debt of the Company and of the Domestic Subsidiaries of the Company secured by Liens (not including Liens permitted under the foregoing exceptions) and the Attributable Debt with respect to Sale and Leaseback Transactions existing at that time (other than Sale and Leaseback Transactions in which the property involved would have been permitted to be subject to a Lien under clause (i) above), does not exceed 10% of Consolidated Net Tangible Assets.

SECTION 3.02.Limitation on Sale and Leaseback Transactions. The Company and the Domestic Subsidiaries of the Company are prohibited from entering into Sale and Leaseback Transactions unless:

(i) the Company or such Domestic Subsidiary of the Company would be entitled to incur Debt secured by a Lien on the Principal Property to be leased without equally and ratably securing the Notes, pursuant to clauses (i) - (vii) under Section 3.01 above; or the Attributable Debt with respect thereto would be an amount permitted under the last paragraph of Section 3.01 above; or

(ii) the Company or such Domestic Subsidiary of the Company shall, within 180 days of the effective date of any such arrangement, apply an amount equal to the proceeds from such Sale and Leaseback Transaction to the payment or other retirement of Debt that ranks senior to or equal with the Notes (other than, in either case, Debt owed by the Company or any Subsidiary), or to the purchase of other Principal Property.

SECTION 3.03.Limitation on Guarantees. The Company and the Domestic Subsidiaries of the Company are prohibited from entering into any agreement pursuant to which any such Domestic Subsidiary of the Company guarantees the payment of Debt incurred by the Company without providing that the Notes be equally and ratably guaranteed by such Domestic Subsidiary of the Company.

ARTICLE IV

REDEMPTION OF THE NOTES

SECTION 4.01.Optional Redemption. The Company may redeem the Notes, at its option, at any time in whole, or from time to time in part. If the Notes are redeemed prior to May 15, 2023, the redemption price for the Notes to be redeemed will equal the greater of:

(i) 100% of the principal amount of the Notes to be redeemed; or

(ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed, exclusive of interest accrued to the date of redemption, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 50 basis points,

plus, in each case, accrued interest to the date the Notes are redeemed (the “Redemption Date”).

If the Notes are redeemed on or after May 15, 2023, the redemption price for the Notes to be redeemed will equal 100% of the principal amount of such Notes, plus accrued interest to the Redemption Date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (the “Remaining Life”) of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of the Reference Treasury Dealer Quotations obtained by the Company for that Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Company is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Company.

“Independent Investment Banker” means J.P. Morgan Securities LLC or Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors, as selected by the Company or, if such firms are unwilling or unable to select the applicable Comparable Treasury Issue or the applicable ratings scale for any Substitute Rating Agency, an independent investment banking institution of national standing appointed by the Company.

“Reference Treasury Dealer” means J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors, and two other independent investment banking institutions of national standing appointed by the Company (each, a “Primary Treasury Dealer”);provided,however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the Notes, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities”, for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounded to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding such Redemption Date.

SECTION 4.02.Purchase of Notes Upon a Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described under Section 4.01 above, the Company will be required to make an offer to each Holder of the Notes to repurchase all or any part (in a principal amount of $2,000 and in integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a repurchase price (the “Purchase Price”) in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the payment date specified in the notice (the “Repurchase Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Repurchase Date following a Change of Control Repurchase Event, the Company will, to the extent lawful:

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Company’s offer;

(ii) deposit with the Paying Agent an amount equal to the aggregate Purchase Price in respect of all the Notes or portions of the Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company.

The Paying Agent will promptly deliver to each Holder of Notes properly tendered, the Purchase Price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered.

The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.

For purposes hereof, the following definitions are applicable:

5.875% Senior Note due 2023

1.	Principal and Interest.

The Company promises to pay the principal of this Note on August 15, 2023.

The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth on the face of this Note, at the rate of 5.875% per annum. The rate at which the Company shall pay interest on the principal amount of this Note on each Interest Payment Date will be subject to adjustment in accordance with Section 2.05 of the Fourth Supplemental Indenture, dated as of July 12, 2013 (the “Supplemental Indenture”), between the Company and The Bank of New York Mellon, as Trustee.

Interest will be payable semiannually (to the Holders of record of the Notes at the close of business on each Regular Record Date, as set forth on the face of this Note, immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing February 15, 2014.

Interest on this Note will accrue from the most recent date to which interest has been paid on this Note (or, if there is no existing default in the payment of interest and if this Note is authenticated between a Regular Record Date and the next Interest Payment Date, from such Interest Payment Date) or, if no interest has been paid, from July 12, 2013. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2.	Indenture.

This Global Security is one of a duly authorized issue of securities of the Company (herein called the “Notes”) issued under the Indenture, dated as of June 1, 2009 (the “Base Indenture”, and, together with the Supplemental Indenture, the “Indenture”), between the Company and The Bank of New York Mellon, as Trustee, as supplemented by the Supplemental Indenture. Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture will control.

The Notes are general unsecured obligations of the Company. The Indenture limits the original aggregate principal amount of the Notes to $500,000,000, but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote together for all purposes as a single class.

3.	Redemption and Repurchase; Discharge Prior to Redemption or Maturity.

This Note is subject to redemption by the Company at any time, as further described in the Indenture. This Note is subject to repurchase by the Company at the option of the holder upon the occurrence of a Change of Control Repurchase Event (as defined in the Supplemental Indenture). There is no sinking fund or mandatory redemption applicable to this Note.

If the Company deposits with the Trustee money or U.S. Government Securities sufficient to pay the then Outstanding principal of, premium, if any, and accrued interest on the Notes to redemption or maturity, the Company may in certain circumstances be discharged from the Indenture and the Notes or may be discharged from certain of its obligations under certain provisions of the Indenture.

4.	Registered Form; Denominations; Transfer; Exchange.

The Notes are in registered form without coupons in denominations of $2,000 principal amount and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Company or Security Registrar may require a Holder to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Company will not be required to issue, register the transfer of or exchange any Note or certain portions of a Note.

5.	Defaults and Remedies.

If an Event of Default (other than certain bankruptcy defaults), as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes then Outstanding may declare all the Notes to be due and payable. If certain bankruptcy defaults with respect to the Company occur and are continuing, the Notes automatically become due and payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes then Outstanding may direct the Trustee in its exercise of remedies.

6.	Amendment and Waiver.

Subject to certain exceptions, the Indenture and the Notes may be amended, or default may be waived, with the consent of the Holders of a majority in principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency.

7.	Authentication.

This Note is not valid until the Trustee signs the certificate of authentication on the other side of this Note.
