securities legend and the applicable restricted securities legend set forth in Exhibit A hereto, which shall be deposited on behalf of the purchasers of the 7.5% Initial Securities represented thereby with the Securities Custodian and
registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as provided in the Indenture. Except as set forth in this Section 2.11(a), beneficial ownership interests in
the Temporary Regulation S Global Security will not be exchangeable for interests in the Rule 144A Global Security, a permanent global security (the “Permanent Regulation S Global Security”, and together with the Temporary
Regulation S Global Security, the “Regulation S Global Security”) or any other 7.5% Security prior to the expiration of the Distribution Compliance Period and then, after the expiration of the Distribution Compliance Period, may be
exchanged for interests in a Rule 144A Global Security or the Permanent Regulation S Global Security only upon certification in form reasonably satisfactory to the Trustee that beneficial ownership interests in such Temporary Regulation S
Global Security are owned either by non-U.S. persons or U.S. persons who purchased such interests in a transaction that did not require registration under the Securities Act. 
 Beneficial interests in Temporary Regulation S Global Securities may be exchanged for interests in Rule 144A Global Securities if (1) such
exchange occurs in connection with a transfer of 7.5% Securities in compliance with Rule 144A and (2) the transferor of the beneficial interest in the Temporary Regulation S Global Security first delivers to the Trustee a written certificate
(in a form satisfactory to the Trustee) to the effect that the beneficial interest in the Temporary Regulation S Global Security is being transferred to a Person (a) who the transferor reasonably believes to be a QIB, (b) purchasing for
its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A, and (c) in accordance with all applicable securities laws of the States of the United States and other jurisdictions. 
 Beneficial interests in a Rule 144A Global Security may be transferred to a Person who takes delivery in the form of an interest in a
Regulation S Global Security, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in the Indenture) to the effect that
such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if applicable) and that, if such transfer occurs prior to the expiration of the Distribution Compliance Period, the interest transferred will
be held immediately thereafter through Euroclear or Clearstream. 
 The Rule 144A Global Security, the Temporary Regulation S Global Security
and the Permanent Regulation S Global Security are collectively referred to herein as “Global Securities”. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made
on the records of the Trustee and the Depository or its nominee as hereinafter provided.

 (b) Book-Entry Provisions. This Section 2.11(b) shall apply only to a Global Security
deposited with or on behalf of the Depository. 
 The Company shall execute and the Trustee shall, in accordance with this
Section 2.11(b), authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depository for such Global Security or Global Securities or the nominee of such Depository and (b) shall
be delivered by the Trustee to such Depository or pursuant to such Depository’s instructions or held by the Trustee as custodian for the Depository. 
 Members of, or Participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee
as the custodian of the Depository or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, 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 Depository or
impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Security. 
 (c) Definitive Securities. Except as provided in this Section 2.11 or Article IV, owners of beneficial interests in Global Securities shall
not be entitled to receive physical delivery of Definitive Securities. 
 SECTION 2.12. Defeasance and Covenant Defeasance. For the
avoidance of doubt, Article Thirteen of the Original Indenture shall be applicable to the 7.5% Securities. 
 SECTION 2.13. Additional
Event of Default. In addition to the Events of Default described in Section 5.01 of the Original Indenture, the acceleration of the maturity of any indebtedness for borrowed money of the Company or any Subsidiary (other than the 7.5%
Securities) having an aggregate principal amount outstanding in excess of an amount equal to 5% of the Company’s Net Tangible Assets (if such acceleration is not rescinded or annulled, or such indebtedness shall not have been discharged, within
15 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding 7.5% Securities a written notice
specifying such default or breach and requiring it to be remedied and stating that such notice is a Notice of Default), shall also constitute an Event of Default with respect of the 7.5% Securities.

	 	(y)	to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations, 

 the Security Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided,
however, that the Definitive Securities surrendered for transfer or exchange: 
 (i) shall be duly endorsed or
accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Security Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 
 (ii) if such Definitive Securities are required to bear a restricted securities legend, they are being transferred or exchanged pursuant
to an effective registration statement under the Securities Act, pursuant to Section 4.02 of this 

  

 10 

 
Third Supplemental Indenture or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and
documents, as applicable: 
 (A) if such Definitive Securities are being delivered to the Security Registrar by a Holder for
registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or 
 (B) if such
Definitive Securities are being transferred to the Company, a certification to that effect; or 
 (C) if such Definitive
Securities are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the
Securities Act: (i) a certification to that effect (in the form set forth on the reverse of the 7.5% Security) and (ii) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance
with the restrictions set forth in the legend set forth in Section 4.05(a) of this Third Supplemental Indenture. 
 SECTION 4.02.
Restrictions on Transfer of a Definitive Security for a Beneficial Interest in a Global Security. A Definitive Security may not be exchanged for a beneficial interest in a Rule 144A Global Security or a Permanent Regulation S Global Security
except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 

(i) certification, in the form set forth on the reverse of the 7.5% Security, that such Definitive Security is either (A) being
transferred to a QIB in accordance with Rule 144A, or (B) being transferred after expiration of the Distribution Compliance Period by a Person who initially purchased such 7.5% Security in reliance on Regulation S to a buyer who elects to hold
its interest in such 7.5% Security in the form of a beneficial interest in the Permanent Regulation S Global Security; and 
 (ii) written instructions directing the Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause
(i)(A)) or Permanent Regulation S Global Security (in the case of a transfer pursuant to clause (i)(B)) to reflect an increase in the aggregate principal amount of the 7.5% Securities represented by the Rule 144A Global Security or Permanent
Regulation S Global Security, as applicable, such instructions to contain information regarding the Depository account to be credited with such increase, 

  

 11 

 
then the Trustee shall cancel such Definitive Security and cause, or direct the Securities Custodian to cause, in accordance with the standing instructions
and procedures existing between the Depository and the Securities Custodian, the aggregate principal amount of 7.5% Securities represented by the Rule 144A Global Security or Permanent Regulation S Global Security, as applicable, to be increased by
the aggregate principal amount of the Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security or Permanent
Regulation S Global Security, as applicable, equal to the principal amount of the Definitive Security so canceled. If no Rule 144A Global Securities or Permanent Regulation S Global Securities, as applicable, are then outstanding, the Company shall
issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers’ Certificate of the Company, a new Rule 144A Global Security or Permanent Regulation S Global Security, as applicable, in the appropriate
principal amount. 
 SECTION 4.03. Transfer and Exchange of Global Securities. (a) The transfer and exchange of Global Securities

beneficial interest in a Global Security shall deliver to the Security Registrar a written order given in accordance with the Depository’s procedures containing information regarding the Participant account of the Depository to be credited with
a beneficial interest in the Global Security. The Security Registrar shall, in accordance with such instructions, instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global
Security and to debit the account of the Person making the transfer the beneficial interest in the Global Security being transferred. 
 (b)
If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Security Registrar shall reflect on its books and records the date and an increase in the principal
amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Security Registrar shall reflect on its books and records the date and a corresponding
decrease in the principal amount of the Global Security from which such interest is being transferred. 
 (c) Notwithstanding any other
provisions of the Indenture (other than the provisions set forth in Section 4.08 of this Third Supplemental Indenture), a Global Security may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee
of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. 
 (d) In the event that a Global Security is exchanged for Definitive Securities pursuant to Section 4.08 of this Third Supplemental Indenture, prior
to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such 7.5% Securities, such 7.5% Securities may be 

  

 12 

 
exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 4.03 (including the certification
requirements set forth on the reverse of the 7.5% Initial Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures

certificate evidencing the Global Securities (and all 7.5% Securities issued in exchange therefor or in substitution thereof): 
 (i) in the case of 7.5% Securities offered otherwise than in reliance on Regulation S, shall bear a legend in substantially the following form: 
 THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS NOTE MAY NOT BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF
SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
 THE HOLDER OF THIS NOTE AGREES FOR THE BENEFIT OF THE COMPANY
THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) TO THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN

PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT. 
 Each Definitive Security shall also bear the following additional legend: 
 IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE SECURITY REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER
COMPLIES WITH THE FOREGOING RESTRICTIONS. 
 (b) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer
Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Security Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated 7.5% Security that does
not bear the legends set forth above and rescind any restriction on the transfer of such 

  

 14 

 
Transfer Restricted Security, if the transferor thereof certifies in writing to the Security Registrar that such sale or transfer was made in reliance on
Rule 144 (such certification to be in the form set forth on the reverse of the 7.5% Security). 
 (c) After a transfer of any 7.5%
Initial Securities or 7.5% Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such 7.5% Initial Securities or 7.5% Private Exchange Securities, as the case may be, all
requirements pertaining to legends on such 7.5% Initial Security or such 7.5% Private Exchange Security will cease to apply, the requirements requiring any such 7.5% Initial Security or such 7.5% Private Exchange Security issued to certain Holders
be issued in global form will cease to apply, and a certificated 7.5% Initial Security or 7.5% Private Exchange Security or an 7.5% Initial Security or 7.5% Private Exchange Security in global form, in each case without restrictive transfer legends,
will be available to the transferee of the Holder of such 7.5% Initial Securities or 7.5% Private Exchange Securities upon exchange of such transferring Holder’s certificated 7.5% Initial Security or 7.5% Private Exchange Security or directions
to transfer such Holder’s interest in the Global Security, as applicable. 
 (d) Upon the consummation of a Registered Exchange Offer
with respect to the 7.5% Initial Securities, all requirements pertaining to such 7.5% Initial Securities that 7.5% Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such 7.5% Initial
Securities that do not exchange their 7.5% Initial Securities, and 7.5% Exchange Securities in certificated or global form, in each case without the restricted securities legends set forth in Exhibit A hereto will be available to Holders that
exchange such 7.5% Initial Securities in such Registered Exchange Offer. 
 (e) Upon the consummation of a Private Exchange with respect to
the 7.5% Initial Securities, all requirements pertaining to such 7.5% Initial Securities that 7.5% Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such 7.5% Initial Securities that do
not exchange their 7.5% Initial Securities, and 7.5% Private Exchange Securities in global form with the global securities legend and the applicable restricted securities legend set forth in Exhibit A hereto will be available to Holders that
exchange such 7.5% Initial Securities in such Private Exchange. 
 SECTION 4.06. Cancellation or Adjustment of Global Security. At
such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, purchased or canceled, such Global Security shall be returned to the Depository for cancellation or retained and canceled by the
Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for certificated 7.5% Securities, purchased or canceled, the principal amount of 7.5% Securities represented by such Global Security shall
be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such
reduction. 
  

 15 

 SECTION 4.07. No Obligation of the Trustee. (a) The Trustee shall have no responsibility or
obligation to any beneficial owner of a Global Security, a member of, or a Participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any Participant or member thereof, with
respect to any ownership interest in the 7.5% Securities or with respect to the delivery to any Participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of
any amount, under or with respect to such 7.5% Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the 7.5% Securities shall be given or made only to or upon the order of the registered
Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the
Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, Participants and any beneficial owners. 
 (b) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the
Indenture or under applicable law with respect to any transfer of any interest in any 7.5% Security (including any transfers between or among Participants of the Depository, members or beneficial owners in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture, and to examine the same to determine substantial compliance as to form with
the express requirements hereof. 
 SECTION 4.08. Definitive Securities. (a) A Global Security is exchangeable for Definitive
Securities only if (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Exchange Act,
(ii) the Company executes and delivers to the Trustee a Company Order that such Global Security shall be so exchangeable and the transfer thereof so registrable or (iii) there shall have occurred and be continuing an “Event of
Default” with respect to the 7.5% Securities. 
 (b) Any Global Security that is exchangeable for Definitive Securities pursuant to
Section 4.08(a) above will be exchanged for Definitive Securities in authorized denominations and registered in such names as DTC or any successor depositary holding such Global Security may direct. Subject to the foregoing, a Global Security
is not exchangeable, except for a Global Security of like denomination to be registered in the name of DTC or any successor depositary or its nominee. In the event that a Global Security becomes exchangeable for Definitive Securities,
(i) Definitive Securities will be issued only in fully registered form in denominations of $2,000 and any integral multiple of $1,000 above that amount; (ii) payment of principal of, and premium, if any, and interest on, the Definitive
Securities will be payable, and the transfer of the Definitive Securities will be registerable, at the office or agency of the Company maintained for such purposes; and (iii) no service charge will be made for any registration of transfer or
exchange of the Definitive Securities, although the Company may require payment of a sum sufficient to cover any tax or governmental charge imposed in connection therewith. 
  

 16

 Reverse of 7.5% Senior Unsecured Note 
 This Senior Unsecured Note is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and
to be issued in one or more series under an Indenture, dated as of September 26, 1996, and as amended and restated on March 23, 1998, and as further amended and restated on March 14, 2001 and as supplemented by the First Supplemental
Indenture dated as of July 25, 2003, the Second Supplemental Indenture dated as of April 12, 2006 and the Third Supplemental Indenture, dated as of May 24, 2007 (as so amended, restated and supplemented, the
“Indenture”), between the Company and Wilmington Trust Company (as successor to JPMorgan Chase Bank, N.A.), as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made 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, unlimited as to principal amount. 
 The Holder of this Security is entitled to the benefits of a Registration Rights Agreement, dated as of May 24, 2007, between the Company and the
initial purchasers named therein (the “Registration Rights Agreement”). Capitalized terms used in this paragraph but not defined herein have the meanings assigned to them in the Registration Rights Agreement. In the event that
(i) the Company fails to file an Exchange Offer Registration Statement with the Commission on or prior to the 90th day after the Issue Date, (ii) if the Exchange Offer Registration Statement is not declared effective by the SEC on or prior
to the 180th day after the Issue Date, (iii) if obligated to file a Shelf Registration Statement because applicable interpretations of the staff of the SEC do not permit the Company to effect a Registered Exchange Offer, a Shelf Registration
Statement is not declared effective by the SEC on or prior to the 180th day after the Issue Date, (iv) if the Exchange Offer is not consummated on or before the 40th day after the Exchange Offer Registration Statement is declared effective,
(v) if obligated to file the Shelf Registration Statement because of circumstances described in Section 2(a), 2(a)(iii), 2(a)(iv) of the Registration Rights Agreement, the Company fails to file the Shelf Registration Statement with the SEC
on or prior to the 30th day (the “Shelf Filing Date”) after the date on which the obligation to file a Shelf Registration Statement arises, or (vi) after the Exchange Offer Registration Statement or the Shelf Registration
Statement, as the case may be, is declared effective, such Registration Statement thereafter ceases to be effective or usable (subject to certain exceptions) (each such event referred to in the preceding clauses (i) through (vi) a
“Registration Default”), interest (the “Additional Interest”) shall accrue (in addition to stated interest on the Securities of this series) from and including the date on which the first such Registration Default
shall occur to but excluding the date on which all Registration Defaults have been cured, at a rate per annum equal to 0.25% of the principal amount of the Securities of this series; provided, however, that such rate per annum shall
increase by 0.25% per annum from and including the 90th day after the first such Registration Default (and each successive 90th day thereafter) unless and until all Registration Defaults have been cured; provided further,
however, that in no event shall the Additional Interest accrue at a rate in excess of 1.0% per annum. The Additional Interest will be payable in cash semiannually in arrears each June 1 and December 1. 
  

 A-9 

 The Securities of this series are not subject to any sinking fund. The Securities shall not be redeemable
at the option of any Holders thereof. 
 The Securities shall not be redeemable at the option of the Company prior to maturity;
provided, however, that the Company may, from time to time, purchase the Securities in the open market or otherwise from time to time. 
 The Indenture contains provisions for defeasance of (a) the entire indebtedness of the Company on this Security and (b) certain restrictive covenants upon compliance by the Company with certain conditions
set forth therein which provisions apply to this Security. 
 If an Event of Default with respect to the Securities of this series shall
occur and be continuing, the principal hereof 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, 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 each series to be affected. The Indenture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the
Indenture and 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 set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to this series, the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a
majority in principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of or interest on this Security on or after the respective due dates expressed herein. 
  

 A-10 

 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this 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 Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are
issuable only in registered form, without coupons, in denominations of $2,000 and any integral multiple of $1,000 above that amount. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and none of the Company, the Trustee
or any agent shall be affected by notice to the contrary. 
 Each Holder of this Security, by acceptance hereof, acknowledges and agrees to
the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein. 
 The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York, without regard to principles of
conflicts of laws. 
 Except as set forth in the second paragraph of this Reverse of 7.5% Senior Unsecured Notes, all terms used in this
Security which are defined in the Indenture shall have the same meanings assigned to them in the Indenture.
