 (REVERSE OF SECURITY) 
 7.000% Notes due 2024 
 This Security 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 November 8, 2000 (herein called the “Indenture”, which term shall have the meaning assigned to it in such
instrument), as supplemented, between the Company and The Bank of New York Mellon Trust Company, N.A. (successor to JPMorgan Chase Bank, N.A., formerly The Chase Manhattan Bank), 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, limited in aggregate principal amount to $100,000,000. 
 The Securities of this series are subject to redemption as follows: 
 The Securities will be redeemable in whole at any time or in part from time to time, at the option of the Company, at a redemption price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed; or
(ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual
basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 50 basis points. 
 The Company
will pay accrued and unpaid interest on the principal amount being redeemed to the date of redemption. 







 In connection with such optional redemption, the following defined terms apply: 
 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of the Securities 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. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average
of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the
average of all such quotations. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers that the Company
appoints to act as the Independent Investment Banker from time to time. 
 “Redemption Date” means the date fixed for redemption of
the Security by or pursuant to the Indenture. 
 “Reference Treasury Dealer” means each of J.P. Morgan Securities Inc. and Deutsche
Bank Securities Inc. and their respective successors, and three other firms that are primary U.S. Government securities dealers (each a “Primary Treasury Dealer”) which the Company specifies from time to time; provided, however, that if
any of them ceases to be a Primary Treasury Dealer, the Company will substitute 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 such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 







 “Treasury Rate” means, with respect to any Redemption Date, the rate per year 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 such Redemption Date.
The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 
 If the Company decides to redeem less than
all of the Outstanding Securities, the Trustee will select the Securities to be redeemed: 
  

	 	•	 	 by lot, 


  

	 	•	 	 pro rata, or 


  

	 	•	 	 by any other method the Trustee considers fair and appropriate. 


 Notice of redemption will be mailed at least 30 but not more than 60 days before the Redemption Date to each Holder of record of the Securities to be redeemed at its registered address. The notice of redemption for
the Securities will state, among other things, the amount of Securities to be redeemed, the Redemption Date, the manner in which the redemption price will be calculated and the place or places that payment will be made upon presentation and
surrender of Securities to be redeemed. Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on any Securities that have been called for redemption at the 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 Holders hereof upon the cancellation hereof. 







 Repurchase upon a Change of Control Triggering Event 
 If a Change of Control Triggering Event (as defined below) occurs, unless the Company has exercised its right to redeem the Securities as described above,
it will be required to make an offer to each Holder to repurchase all or, at the Holder’s option, any part (equal to $2,000 or any multiple of $1,000 in excess thereof), of each Holder’s Securities pursuant to the offer described below
(the “Change of Control Offer”) on the terms set forth in the Securities. In the Change of Control Offer, the Company will be required to offer to repurchase each Holder’s Securities in cash at a price equal to 101% of the aggregate
principal amount of Securities repurchased, plus any accrued and unpaid interest on the Securities repurchased to, but not including, the date of repurchase (the “Change of Control Payment”). 
 Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control (as defined below), but
after the public announcement of a pending Change of Control, the Company will be required to send to each Holder of Securities, a notice describing the transaction that constitutes or may constitute the Change of Control Triggering Event and
offering to repurchase such Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “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 Triggering Event occurring on or prior to the Change of Control Payment Date.

 On the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 
  

	 	•	 	 accept for payment all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer; 










	 	•	 	 deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered; and



  

	 	•	 	 deliver or cause to be delivered to the Trustee the Securities properly accepted together with an officer’s certificate stating the aggregate principal amount
of Securities or portions of Securities being purchased by the Company. 


 The paying agent will be required to promptly
mail, to each Holder who properly tendered Securities, the Change of Control Payment for such Securities, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new note
equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each new note will be in a principal amount of $2,000 or a multiple of $1,000 in excess thereof. 
 The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes an offer to purchase
the Securities in the manner, at the times and otherwise in compliance with the requirements for an offer to purchase made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer. In the event
that such third party terminates or defaults its offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event. 

The Company will not repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an event of default under
the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 
 To the
extent that we are required to offer to repurchase the notes upon the occurrence of a Change of Control Triggering Event, we may not have sufficient funds to repurchase the notes in cash at such time. In addition, our ability to repurchase the notes
for cash may be limited by law or the terms of other agreements relating to our indebtedness outstanding at the time. The failure to make such repurchase would result in a default under the notes. 
 We will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (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 provision of any such
securities laws or regulations conflicts with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer
provisions of the notes by virtue of any such conflict. 
 The definition of Change of Control includes a phrase relating to the direct or
indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase
“substantially all”, there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require us to repurchase its notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of our assets and those of our subsidiaries, taken as a whole, to another person or group may be uncertain. In such case, holders of the notes may not be able to resolve this uncertainty without resorting to legal
action 
 The provisions in the Indenture and the notes relating to change of control transactions will not necessarily afford you protection
in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, restructuring, merger or other similar transaction involving us. These transactions may not involve a change in voting power or beneficial
ownership or, even if they do, may not involve a change of the magnitude or on the terms required under the definition of Change of Control Triggering Event. 







 For purposes of the repurchase provisions of the Securities, the following terms will be applicable:

 “Change of Control” means the occurrence of any one of the following: (1) the direct or indirect sale, lease,
transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s properties or assets and those of its
subsidiaries, taken as a whole, to one or more persons, other than to the Company or one of its subsidiaries; (2) the first day on which a majority of the members of the Company’s board of directors is not composed of Continuing Directors
(as defined below); (3) the consummation of any transaction including, without limitation, any merger, amalgamation, arrangement or consolidation the result of which is that any person becomes the beneficial owner, directly or indirectly, of
more than 50% of the Company’s Voting Stock , measured by voting power rather than number of shares; (4) the Company consolidates with, or merge 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 outstanding Voting Stock of the Company or of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the
shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the
surviving person immediately after giving effect to such transaction; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution (other than its liquidation into a newly formed holding company). Notwithstanding the
foregoing, a transaction described in clause (3) above will not be deemed to involve a Change of Control if (1) the Company becomes a direct or indirect wholly-owned subsidiary of a holding 








 
company (which shall include a direct or indirect parent company of such holding company) and (2)(A) the direct or indirect Holders of the Voting Stock
of such holding company immediately following that transaction are substantially the same as, and hold in substantially the same proportions as, the Holders of the Company’s Voting Stock immediately prior to that transaction or
(B) immediately following that transaction no person, other than a holding company satisfying the requirements of this sentence, is the beneficial owner, directly or indirectly of more than 50% of the then outstanding Voting Stock, measured by
voting power, of such holding company or its parent company. Following any such transaction, references in this definition to the Company shall be deemed to refer to such holding company. For the purposes of this definition, “person” and
“beneficial owner” have the meanings used in Section 13(d) of the Exchange Act. 
 “Change of Control Triggering Event” means
the Securities cease to be rated Investment Grade by each of the Rating Agencies on any date during the 60-day period (the “Trigger Period”) following the earlier date of (1) the first public announcement of the Change of Control or
the Company’s intention to effect a Change of Control and (2) the consummation of such Change of Control, which Trigger Period will be extended following consummation of a Change of Control for so long as the rating of the Securities is
under publicly announced consideration for possible downgrade by any of the Rating Agencies. Unless at least one Rating Agency is providing a rating for the long-term unsecured debt of the Company at the commencement of any Trigger Period, the
Securities will be deemed to have ceased to be rated Investment Grade during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of
Control unless and until such Change of Control has actually been consummated. 







 “Continuing Directors” means, as of any date of determination, any member of the
Company’s board of directors who (1) was a member of the Company’s board of directors on the date the Securities were issued; or (2) was nominated for election, elected or appointed to the Company’s board of directors with
the approval of a majority of the Continuing Directors who were members of the Company’s board of directors at the time of such nomination, election or appointment (either by specific action of the board of directors or by approval by such
directors of the Company’s proxy statement in which such member was named as a nominee for election as a director). 
 “Fitch”
means Fitch Inc., and its successors. 
 “Investment Grade” means a rating equal to or higher than BBB- (or the equivalent)
by Fitch, Baa3 (or the equivalent) by Moody’s or BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company. 
 “Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors. 
 “Rating Agencies” means (a) each of Fitch, Moody’s and S&P; and (b) if any of the Rating Agencies ceases to provide
rating services to issuers or investors, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act that is selected by the Company (as certified by the
Company’s chief executive officer or chief financial officer) as a replacement for Fitch, Moody’s or S&P, or all of them, as the case may be. 
 “S&P” means Standard & Poor’s Rating Services, a division of The McGraw-Hill Companies, Inc., and its successors. 







 “Voting Stock” of any specified person as of any date means the capital stock of such
person that is at the time entitled to vote generally in the election of the board of directors of such person. 
 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.

 No sinking fund is provided for the Securities. 
 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 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 as Trustee and
offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment
of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 
 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 any premium 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 any premium 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 in denominations of $2,000 and integral multiples of
$1,000. 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 be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Security is a Global Security and is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 305 thereof on transfers and exchanges of Global
Securities. 







 This Security and the Indenture shall be governed by and construed in accordance with the laws of the
State of New York. 
 All terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the
Indenture.
