NOW, THEREFORE:

For and in consideration of the premises and purchase of the Debt Securities of any series issued on or after the date hereof by the Holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of the Debt Securities of any such series, as follows:

ARTICLE I

CERTAIN PROVISIONS OF GENERAL APPLICATION

SECTION 101 Definitions.

For all purposes of the Indenture and this Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires:

(1) the terms defined in this Article I have the meanings assigned to them in this Article I;

(2) the words “herein,” “hereof” and “hereunder” and other words of similar import refer to the Indenture and this Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision; and

(3) capitalized terms used but not defined herein are used as they are defined in the Indenture.

“Attributable Indebtedness” with respect to a Sale/Leaseback Transaction means, as of the time of determination, (i) if the obligation with respect to such Sale/Leaseback Transaction is a Capitalized Lease Obligation, the amount of such obligation determined in accordance with GAAP and included in the financial statements of the lessee or (ii) if the obligation with respect to such Sale/Leaseback Transaction is not a Capitalized Lease Obligation, the total Net Amount of Rent required to be paid by the lessee under such lease during the remaining term thereof (including any period for which the lease has been extended), discounted from the respective due dates thereof to such determination date at the rate per annum borne by the Notes compounded semi-annually.

“Change of Control” means the occurrence of any of the following after the date of issuance of the Notes:

1. the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to the Company or one of its Subsidiaries;

2. the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of Voting Stock representing more than 50% of the voting power of the outstanding Voting Stock of the Company;

3. the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges with or into the Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock or Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the Voting Stock of the Company outstanding immediately prior to such transaction constitutes, or is converted into or exchanged for, Voting Stock representing at least a majority of the voting power of the Voting Stock of the surviving Person immediately after giving effect to such transaction;

4. the first day on which a majority of the members of the Company’s Board of Directors are not Continuing Directors; or

5. the adoption of a plan relating to the liquidation or dissolution of the Company.

THE NOTES

SECTION 201 Title and Terms.

There is hereby created under the Indenture a series of Debt Securities known and designated as the “6.50% Notes due 2020” of the Company. The aggregate principal amount of Notes that may be authenticated and delivered under this Supplemental Indenture is initially limited to $150,000,000, except for Notes authenticated and delivered upon reregistration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.07, 2.08, 2.09 or 9.04 of the Indenture.

The Company may without notice to or the consent of the Holders of the Notes, issue in separate offerings additional notes having the same ranking, interest rate, maturity and other terms as the Notes (other than the date of issuance and, under certain circumstances, the first interest payment date following the issue date of such additional notes). Any such additional notes, together with the Notes, will form a single series of Debt Securities under the Indenture.

The Stated Maturity for payment of principal of the Notes shall be April 15, 2020, and the Notes shall bear interest at the rate of 6.50% per annum, from April 13, 2010, or the most recent interest payment date to which interest has been paid or duly provided for, payable semi-annually in arrears on April 15 and October 15 of each year (commencing October 15, 2010, to the Persons in whose names the Notes are registered at the close of business on April 1 or October 1, as the case may be, next preceding such interest payment date, until principal thereof is paid or made available for payment.

The Notes shall be initially issued in the form of a Global Security and the depositary for the Notes shall be The Depository Trust Company, New York, New York (the “Depositary”).

The Notes shall not be subject to any sinking fund.

The Notes shall be in registered form without coupons and shall be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The form of Note attached hereto as Exhibit A is hereby adopted, pursuant to Section 9.01(j) of the Indenture, as a form of Debt Securities of a series that consists of the Notes.

SECTION 202 Optional Redemption.

(a) The provisions of Article III of the Indenture, as amended by the provisions of this Supplemental Indenture, shall apply to the Notes.

(b) The Notes are subject to redemption upon notice mailed at least 30 days but not more than 60 days prior to the redemption date to each Registered Holder. The Notes may be redeemed, as a whole or in part, at the option of the Company at a redemption price equal to the greater of:

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

(ii) the sum of the present values of the Remaining Scheduled Payments thereon discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 45 basis points,

plus, in either case, accrued interest on the principal amount being redeemed to the date of redemption.

Unless the Company defaults in payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

SECTION 203 Purchase upon a Change of Control Triggering Event.

(a) Upon the occurrence of a Change of Control Triggering Event with respect to the Notes, unless the Company has exercised its right to redeem the Notes in full as set forth in Section 202 of this Supplemental Indenture, by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of Notes will have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to the offer described in this Section 203 (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

(b) Unless the Company has exercised its right to redeem the Notes, within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to the Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to send, by first class mail, a notice to each Holder of Notes, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. The notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date the notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

(i) accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of 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 or portions of Notes being purchased and that all conditions precedent to the Change of Control Offer and to the purchase by the Company of Notes pursuant to the Change of Control Offer have been complied with.

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

(e) The Company will comply in all material respects 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 Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under this Section 203 by virtue of any such conflict.

SECTION 204 Limitation on Liens.

[Form of Reverse of Global Note]

This Debt Security is one of a duly authorized issue of securities of the Issuer (herein called the “Debt Securities”), issued and to be issued in one or more series under an Indenture dated as of April 13, 2010 (the “Base Indenture”) as supplemented by the First Supplemental Indenture dated as of April 13, 2010 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Issuer and U.S. Bank National Association, as trustee (herein called the “Trustee”), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Trustee and the Registered Holders of the Debt Securities and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. This Debt Security is one of the series designated on the face hereof.

This Debt Security is subject to redemption upon notice mailed at least 30 days but not more than 60 days prior to the redemption date to each Registered Holder. This Debt Security may be redeemed, as a whole or in part, at the option of the Issuer at a redemption price equal to the greater of (a) 100% of the principal amount to be redeemed and (b) the sum of the present values of the Remaining Scheduled Payments (as defined in the Supplemental Indenture) thereon discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 45 basis points, plus, in either case, accrued interest on the principal amount being redeemed to the date of redemption. Unless the Issuer defaults in payment of the redemption price, on and after the applicable redemption date, interest will cease to accrue on the Debt Securities or portions thereof called for redemption.

Upon the occurrence of a Change of Control Triggering Event with respect to this Debt Security, unless the Issuer has exercised its right to redeem this Debt Security in full as set forth in Section 202 of the Supplemental Indenture, by giving irrevocable notice to the Trustee in accordance with the Indenture, each Holder of this Debt Security will have the right to require the Issuer to purchase all or a portion of such Holder’s Debt Security pursuant to a Change of Control Offer, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of this Debt Security on the relevant record date to receive interest due on the relevant interest payment date.

Unless the Issuer has exercised its right to redeem this Debt Security, within 30 days following the date upon which the Change of Control Triggering Event occurred with respect to this Debt Security or, at the Issuer’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Issuer will be required to send, by first class mail, a notice to each Holder of this Debt Security, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. The notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days after the date the notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(i) accept or cause a third party to accept for payment all Debt Securities of this series or portions of Debt Securities of this series properly tendered pursuant to the Change of Control Offer;

(ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Debt Securities of this series or portions of Debt Securities of this series properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Debt Securities of this series properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Debt Securities of this series or portions of Debt Securities of this series being purchased and that all conditions precedent to the Change of Control Offer and to the purchase by the Issuer of the Debt Securities of this series pursuant to the Change of Control Offer have been complied with.

The Issuer will not be required to make a Change of Control Offer with respect to this Debt Security if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Issuer and such third party purchases all the Debt Securities of this series properly tendered and not withdrawn under its offer.

The Issuer will comply in all material respects 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 this Debt Security as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of this Debt Security, the Issuer will comply with those securities laws and regulations and will not be deemed to have breached its obligations under Section 203 of the Supplemental Indenture by virtue of any such conflict.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Debt Security or certain restrictive covenants and Events of Default with respect to this Debt Security, in each case upon compliance with certain conditions set forth in the Indenture. Such provisions shall be applicable to this Debt Security.

If an Event of Default with respect to this Debt Security shall occur and be continuing, the principal of and interest on this Debt Security may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, without notice to any Holder but with the consent of Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such supplemental indenture, the Issuer and the Trustee at any time to enter into an indenture or supplemental indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series. The Indenture also permits, with certain exceptions as therein provided, prior to the acceleration of the maturity of the Debt Securities of any series, the Holders of specified percentages in aggregate principal amount of the Debt Securities of that series at the time Outstanding may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series specified in the terms thereof. Any such consent or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and of any Debt Security issued upon the registration of transfer hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Debt Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Debt Security shall not have the right to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to the Debt Securities of this series and of the continuance thereof and unless the Holders of not less than 25% in aggregate principal amount of the Outstanding Debt Securities of this series shall have made written request upon the Trustee to institute such action or proceedings in respect of such Event of Default in its own name as Trustee thereunder and shall have offered to the Trustee such reasonable indemnity, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustee by the Holders of a majority in aggregate principal amount of the Debt Securities of this series at the time Outstanding. The foregoing shall not apply to any suit instituted by the Holder of this Debt Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Debt Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Debt Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Debt Security is registrable in the Debt Security Register, upon surrender of this Debt Security for registration of transfer at the office or agency of the Issuer in any Place of Payment, duly endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Issuer, the Trustee and the Registrar duly executed by the Registered Holder or the Registered Holder’s attorney duly authorized in writing, and thereupon the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Debt Security or Debt Securities of authorized denominations for a like aggregate principal amount.

The Debt Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debt Securities of this series are exchangeable in whole or in part for a like aggregate principal amount of Debt Securities of this series and of like tenor and terms of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, no service charge shall be made for any such registration of transfer of Debt Securities, but the Issuer 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 for registration of transfer of this Debt Security, the Issuer, the Trustee, any paying agent or any Registrar may deem and treat the Person in whose name this Debt Security is registered as the absolute owner hereof for all purposes, whether or not this Debt Security shall be overdue, and none of the Issuer, the Trustee, any paying agent or any Registrar shall be affected by notice to the contrary.

All terms used in this Debt Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
