Additional Covenants

At any time when the Company is not subject to Section 13 or Section 15(d) of the Exchange Act, so long as any Notes remain outstanding, upon the request of a holder of the Notes, the Company will promptly furnish or cause to be furnished the information specified under Rule 144A(d)(4) of the Securities Act to such holder.

          SECTION 3.02. Restriction on Liens; Restriction on Sale and Lease-Back Transactions.

          (a) So long as any of the Notes remain outstanding, subject to Section 3.02(c) below, the Company will not, and will not permit any Restricted Subsidiary to, issue, assume or guarantee any debt for money borrowed (“debt”) if that debt is secured by a mortgage on any Principal Property, or on any shares of stock or indebtedness of any Restricted Subsidiary (whether the Principal Property, shares of stock or indebtedness is owned at or acquired after August 17, 2011), without in any such case effectively providing that the Notes shall be secured equally and ratably with or prior to such debt until such time as such debt is no longer so secured by such mortgage. This restriction, however, shall not apply to: (i) mortgages on property of any corporation or other Person existing at the time such corporation or other Person becomes a Restricted Subsidiary; (ii) mortgages on property of a corporation or other Person existing at the time that corporation or other Person is merged into or consolidated with the Company or a Restricted Subsidiary or at the time of a sale, transfer, conveyance or the disposition of all or substantially all of the properties or assets of that corporation or other Person to the Company or a Restricted Subsidiary; (iii) mortgages on any property the Company or any Restricted Subsidiary acquires, constructs or improves that secure debt issued, assumed or guaranteed (or issued, assumed or guaranteed pursuant to a commitment entered into) prior to, at the time of or within 12 months after the acquisition or completion of construction or improvement of the property (or, in the case of property constructed or improved, if later, the commencement of commercial operation of the property) for the purpose of financing all or any part of the purchase price of the property or the cost of the construction or improvement (together with, in the case of construction or improvement, mortgages on property previously owned by the Company or any Restricted Subsidiary to the extent constituting unimproved real property on which the property being constructed or the improvement is located); (iv) mortgages securing debt owing by the Company or any Restricted Subsidiary to the Company or another Restricted Subsidiary; (v) mortgages on property of the Company or a Restricted Subsidiary in favor of the United States of

America or any State thereof, or any department, agency or instrumentality or political subdivision of the United States of America or any State thereof, or in favor of any other country, or any political subdivision thereof, to secure any debt incurred for the purpose of financing all or any part of the purchase price or the cost of construction or improvement of the property subject to such mortgages, including mortgages incurred in connection with pollution control, industrial revenue or similar financings; (vi) mortgages existing at the Issue Date; (vii) mortgages on inventory to secure current liabilities of debt; and (viii) any extension, renewal or replacement or successive extensions, renewals or replacements, in whole or in part, of any mortgage referred to in the clauses immediately above if the amount of debt secured by the extended, renewed or replacement mortgage does not exceed the amount of the debt refinanced (plus accrued interest and premiums with respect thereto) plus transaction expenses related thereto and such mortgage is limited to the property secured by the original mortgage plus improvements thereon.

          (b) So long as any of the Notes remain outstanding, subject to Section 3.02(c) below, the Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction of any Principal Property unless (i) the Company or such Restricted Subsidiary would be entitled to issue, assume or guarantee debt secured by a mortgage upon the Principal Property involved in amount at least equal to the Attributable Debt for that transaction without equally and ratably securing the Notes, (ii) an amount in cash equal to the Attributable Debt for that transaction is applied prior to, at the time of or within 12 months after that transaction to the retirement of Notes or other debt of the Company or a Restricted Subsidiary, which by its terms matures at or is extendible or renewable at the option of the obligor to a date more than 12 months after its creation and which, in the case of such debt of the Company, is not subordinate in right of payment to the Notes or (iii) prior to, at the time of or within 12 months after such transaction, the Company or a Restricted Subsidiary uses an amount equal to the Attributable Debt for the purchase of any asset or any interest in an asset which would qualify, after purchase, as Principal Property. This Section 3.02(b) does not apply to any Sale and Leaseback Transaction (i) entered into in connection with an industrial revenue, pollution control or similar financing or any Sale and Leaseback Transaction or (ii) in which the only parties involved are the Company and any Subsidiary or Subsidiaries. When calculating the amount of Attributable Debt, any Attributable Debt for these Sale and Leaseback Transactions will be excluded.

          (c) In addition to the exceptions set forth under Sections 3.02(a) and 3.02(b) above, the Company and any Restricted Subsidiary may incur debt secured by mortgages and enter into additional Sale and Leaseback Transactions otherwise prohibited by (and not permitted under the exceptions to) Sections 3.02(a) or 3.02(b) as long as the total of such debt secured by mortgages plus the Attributable Debt in respect of such Sale and Leaseback Transactions does not exceed 15% of the Company’s Consolidated Net Tangible Assets.

          SECTION 3.03. Applicability. The covenants set forth in Sections 3.01 and 3.02 are applicable only to the Securities of the series of the Notes and are solely for the benefit of the Holders of the Notes.

Transfer and Exchange

          SECTION 4.01. Transfer and Exchange of Global Securities; Limited Rights of Beneficial Owners. (a) The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

          (1) Each Global Security authenticated under this First Supplemental Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Note for all purposes of the Indenture.

          (2) Notwithstanding any other provision in the Original Indenture or this First Supplemental Indenture, no Global Security may be exchanged in whole or in part for Notes registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless

     (A) such Depositary has notified the Company that it (i) is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, or

     (B) the Company has executed and delivered to the Trustee a Company Order stating that such Global Security shall be exchanged in whole for Definitive Securities.

If the Company receives a notice of the kind specified in clause (A) above, the Company may, in its sole discretion, designate a successor Depositary for such Global Security within 90 days after receiving such notice. If the Company designates a successor Depositary as aforesaid, such Global Security shall promptly be exchanged in whole for one or more other Global Securities registered in the name of the successor Depositary, whereupon such designated successor shall be the Depositary for such successor Global Security or Global Securities and the provisions of clauses (1), (2), (3) and (4) of this provision shall continue to apply thereto.

          (3) Subject in all cases to clause (2) above, any exchange of a Global Security for other Notes may be made in whole or in part, and all Notes issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

          (4) Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to Section 304, 306, 906 or 1107 of the Original Indenture or this Article IV or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless upon a Definitive Securities Issuance Date such Note is issued as a Definitive Security.

          (b) Upon the date 90 days after the Company has received notice from the Depositary pursuant to Section 4.01(a)(2)(A) and has not appointed a successor Depositary or

has delivered a Company Order to the Trustee pursuant to Section 401(a)(2)(B) or, in either case, such earlier date as the Company elects by written notice to the Trustee (the “Definitive Securities Issuance Date”), (x) the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons; (y) the Company shall execute, and upon a Company Order the Trustee shall authenticate and deliver, Definitive Securities in a like aggregate principal amount as the outstanding Global Securities registered, Definitive Securities in such names and authorized denominations as the Depositary shall instruct the Security Registrar in accordance with the Applicable Procedures; and (2) the Security Registrar shall cause the aggregate principal amount of such outstanding Global Securities to be reduced to zero pursuant to Section 4.08. The Trustee shall deliver such Definitive Securities to the Persons in whose names such Definitive Securities are so registered. Any Definitive Security issued in exchange for a beneficial interest in a Restricted Global Security pursuant to this Section 4.01 shall bear the Private Placement Legend and shall be subject to all restrictions on transfer contained therein. Notwithstanding the foregoing, a beneficial interest in the Regulation S Global Security may not be exchanged for a Definitive Security prior to the expiration of the Restricted Period. Neither the Company nor the Security Registrar will be liable for any delay by the Depositary in identifying the owners of beneficial interests in a Global Security, and each of the Company and the Security Registrar may conclusively rely on, and will be protected in relying on, instructions from the Depositary for all purposes of the Indenture.

          (c) The Company, the Trustee and every Person who takes or holds any beneficial interest in a Global Security agree that:

          (1) the Company and the Trustee may deal with the Depositary as sole owner of the Global Security and as the authorized representative of such Person;

          (2) such Person’s rights in the Global Security shall be exercised only through the Depositary and shall be limited to those established by law and agreement between such Person and the Depositary and/or Participants and Indirect Participants of the Depositary;

          (3) the Depositary and its participants make book-entry transfers of beneficial ownership among, and receive and transmit distributions of principal and interest on the Global Securities to, such Persons in accordance with the Applicable Procedures of the Depositary;

          (4) none of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests; and

          (5) notwithstanding the foregoing, (x) subject to the provisions of Section 4.01(c)(2), the Holder of a Global Security shall be entitled to grant proxies and otherwise authorize any Person, including Participants and Indirect Participants and Persons that may hold interests through Participants and Indirect Participants, to take any action which a Holder is entitled to take under the Indenture or the Notes; and (y) nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any

written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

The transfer and exchange of beneficial interests in the Global Securities shall be effected through the Depositary, in accordance with the provisions of this First Supplemental Indenture and the Applicable Procedures.

Transfers of beneficial interests in the Global Securities also shall require compliance with either subparagraph (a) or (b) below, as applicable, as well as one or more of the other following provisions of this Article IV, as applicable:

          (a) Transfer of Beneficial Interests in the Same Global Security. Beneficial interests in any Restricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Security in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Security may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser), except pursuant to Rule 144A. Beneficial interests in any Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in such Unrestricted Global Security. No written orders or instructions shall be required to be delivered to the Security Registrar to effect the transfers described in the preceding sentence of this Section 4.02(a).

          (b) All Other Transfers and Exchanges of Beneficial Interests in Global Securities. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 4.02(a) above, the transferor of such beneficial interest must deliver to the Security Registrar either:

     (A) (i) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged; and

      (ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

Upon consummation of a Registered Exchange Offer by the Company in accordance with Section 4.06, the requirements of this Section 4.02(b) shall be deemed to have been satisfied upon receipt by the Security Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial interests in the Restricted Global Securities (or transmitted to the Security Registrar via the Depositary’s book-entry system). Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Securities contained in the Indenture, the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of each relevant Global Security pursuant to Section 4.08.

          (c) Transfer of Beneficial Interests to Another Restricted Global Security. A beneficial interest in any Restricted Global Security may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Security if the transfer complies with the requirements of Section 4.02(b) above and the Security Registrar receives the following:

     (i) if the transferee will take delivery in the form of a beneficial interest in the 144A Global Security, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; and

     (ii) if the transferee will take delivery in the form of a beneficial interest in the Regulation S Global Security, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof.

          (d) Transfer and Exchange of Beneficial Interests in a Restricted Global Security for Beneficial Interests in the Unrestricted Global Security.

          (i) such exchange or transfer is effected pursuant to a Registered Exchange Offer in accordance with the applicable Registration Rights Agreement and the holder of the beneficial interest to be transferred, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable Letter of Transmittal (or via the Depositary’s book-entry system) that, among other things, it is not (i) a Person participating in the distribution of the Exchange Securities or (ii) an affiliate (as defined in Rule 144) of the Company and that any Exchange Securities to be acquired by such holder will be acquired in the ordinary course of its business;

          (ii) such transfer is effected pursuant to a Shelf Registration Statement in accordance with the applicable Registration Rights Agreement;

          (iii) such transfer is effected by an Exchanging Dealer pursuant to an Exchange Offer Registration Statement in accordance with the applicable Registration Rights Agreement; or

If any such transfer is effected pursuant to subparagraph (ii) or (iv) above at a time when an Unrestricted Global Security has not yet been issued, the Company shall issue and, upon receipt of a Company Order in accordance with Section 303 of the Original Indenture, the Trustee shall authenticate one or more Unrestricted Global Securities in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to subparagraph (ii) or (iv) above.

From and after any Definitive Securities Issuance Date, upon request by a Holder of Definitive Securities and such Holder’s compliance with the provisions of this Section 4.05, the Security Registrar shall register the transfer of, in the name of the designated transferee or transferees, one or more new Definitive Securities, or exchange Definitive Securities for other Definitive Securities, in each case, of any authorized denominations and of like aggregate principal amount. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Security Registrar the Definitive Securities to be transferred or exchanged duly endorsed, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or such Holder’s attorney duly authorized in writing.

THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

     BY ITS ACQUISITION AND HOLDING OF THIS SECURITY THE HOLDER THEREOF WILL BE DEEMED TO HAVE REPRESENTED, WARRANTED AND AGREED THAT EITHER (I) IT IS NOT AND WILL NOT BE FOR SO LONG AS IT HOLDS ANY SECURITY (OR INTEREST IN A SECURITY) AN EMPLOYEE BENEFIT PLAN OR ARRANGEMENT SUBJECT TO THE FIDUCIARY RESPONSIBILITY REQUIREMENT OF TITLE I OF U.S. EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (“ERISA”), A “PLAN” OR ARRANGEMENT SUBJECT TO SECTION 4975 OF THE U.S. INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), OR AN ENTITY WHOSE UNDERLYING ASSETS INCLUDE PLAN ASSETS BY REASON OF SUCH EMPLOYEE BENEFIT PLAN OR PLAN’S INVESTMENT IN THE ENTITY, OR A GOVERNMENTAL, NON-U.S., CHURCH OR OTHER PLAN WHICH IS SUBJECT TO ANY FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SUBSTANTIALLY SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (“SIMILAR LAWS”), OR (II) THE PURCHASE, HOLDING AND DISPOSITION OF THIS SECURITY WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR, IN THE CASE OF A GOVERNMENTAL, NON-U.S., CHURCH OR OTHER PLAN, A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS.

     (ii) Notwithstanding the foregoing, any Global Security or Definitive Security issued pursuant to Sections 4.02(d), 4.05(b), 4.05(c) or 4.06 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

          (b) (i) The Company, acting in its discretion, may remove (and, at the request of any Holder in accordance with Sections 4.07(b)(v) or (vi), as applicable, will remove) the Private Placement Legend from any Restricted Security at any time on or after the Resale Restriction Termination Date applicable to such Restricted Security. Without limiting the generality of the preceding sentence, the Company may effect such removal by issuing and delivering, in exchange for any Restricted Security, an Unrestricted Security without the Private Placement Legend, registered to the same Holder and in an equal principal amount and constituting a Global Security (if the exchanged Security was a Restricted Global Security) or a Definitive Security (if the exchanged Security was a Restricted Definitive Security) or, in lieu of issuance and delivery of a new Unrestricted Global Security for a Restricted Global Security, causing the Trustee to endorse an increase in aggregate principal amount of any then outstanding Unrestricted Global Security equal to the aggregate principal amount of such Restricted Global Security; and upon receipt by the Trustee of a Company Order stating that the Resale Restriction Termination Date applicable to such Restricted Security has occurred and requesting the authentication and delivery of an Unrestricted Security (or endorsement of an increase in aggregate principal amount of any then outstanding Unrestricted Global Security as aforesaid) in exchange therefor (which Company Order shall not be required to be accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date),

CERTIFICATE OF AUTHENTICATION

     This is one of the Securities of the series designated herein and referred to in the within-mentioned Indenture.

Dated:                     

     This Security is one of a duly authorized issue of senior securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of October 28, 2008, as supplemented by the First Supplemental Indenture (herein so called) thereto, dated as of August 17, 2011 (herein called the “Indenture”, which term shall have the meaning assigned to it in such First Supplemental Indenture), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, the aggregate principal amount of which is not limited. The aggregate principal amount of Securities of this series authorized for issuance pursuant to the Indenture is limited to the $750,000,000 in aggregate principal amount of Securities of this series initially authorized for issuance on the Issue Date plus such additional amounts of Securities of this series as may be authorized for issuance from time to time thereafter in accordance with the provisions of the Indenture (except for Securities of this series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this series pursuant to the Indenture).

     The Securities of this series are subject to redemption upon prior notice, as provided below, at any time, as a whole or in part, at the election of the Company. If the Securities of this series are redeemed prior to May 15, 2021, the Redemption Price will be equal to the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series to be redeemed from the Redemption Date to the Stated Maturity of the Securities of this series to be redeemed (exclusive of any interest accrued to the Redemption Date), discounted to the date on which the Securities of this series are to be redeemed on a semi-annual basis assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 15 basis points, plus any interest accrued but not paid on the Securities of this series to be redeemed to the date on which the Securities of this series are to be redeemed (subject to the right of Holders on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date). If the Securities of this series are redeemed on or after May 15, 2021, the Redemption Price will be equal to 100% of the principal amount of the Securities of this series to be redeemed, plus any interest accrued but not paid on the Securities of this series to be redeemed to the date on which the Securities of this series are to be redeemed (subject to the right of Holders on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date). Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Securities of this series or portions thereof called for redemption. If less than all of the Securities of this series are to be redeemed at any time, the Trustee will select Securities of this series for redemption on a pro rata basis. No Securities of this series of $2,000 or less can be redeemed in part. Notices of redemption will be delivered at least 30 but not more than 60 days before the Redemption Date to each Holder of Securities of this series to be redeemed at its registered address, except that notices may be mailed more than 60 days prior to a Redemption Date if the notice is

issued in connection with a Covenant Defeasance or Defeasance with respect to the Securities of this series or a satisfaction and discharge of the Indenture with respect to Securities of this series. Notice of any redemption, may, at the Company’s discretion, be subject to one or more conditions precedent. A notice of redemption need not set forth the exact Redemption Price but only the manner of calculation thereof.

     “Treasury Rate” means, with respect to any Redemption Date for the Securities of this series, (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 with respect to Securities of this series (if no maturity is within three months before or after the Stated Maturity for the Securities of this series, 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, rounding to the nearest month) or (ii) if that 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 semiannual 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 that Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

     “Comparable Treasury Issue” means, with respect to the Securities of this series, the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series to be redeemed 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 Securities of this series to be redeemed. “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company.

     “Comparable Treasury Price” means with respect to any Redemption Date for any Securities of this series (i) the average of four Reference Treasury Dealer Quotations for that Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

     “Reference Treasury Dealer” means each of J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated and four other primary U.S. Government securities dealers in the United States (each, a “Primary Treasury Dealer”) appointed by the Trustee in consultation with the Company; 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, the average, as determined by the Trustee, 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 that Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day preceding that Redemption Date.

     In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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

     If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared, or shall automatically become, due and payable in the manner and with the effect provided in the Indenture.

     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 Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
