at the option of the Company on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2036 Notes to be redeemed and (ii) the sum of the present values of the principal
amount of the 2036 Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their
respective scheduled payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as

comparable maturity with the Remaining Life.

substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotation” 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., The City of New York time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate”
means, with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any
successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury
Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

Notwithstanding Section 1104 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the
Redemption Price but only the manner of calculation thereof. 
 The Company shall notify the Trustee of the Redemption Price with respect to the foregoing
redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price. 
 If less than all of the
2036 Notes are to be redeemed, the Trustee shall select the 2036 Notes or portions of 2036 Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption 2036 Notes and portions of 2036
Notes in amounts of whole multiples of $ 1,000. 
 The 2036 Notes shall not have a sinking fund.

successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate
principal amount of a 144A Global Note may from time to time be increased or decreased by adjustments made on the, records of the Security Custodian as hereinafter provided, subject in each case to compliance with the applicable procedures of the
Security Custodian and the Depositary. 
 (ii) 2036 Notes offered and sold in reliance on Regulation S shall be issued initially in the form

time after expiration of the Restricted Period, the Regulation S Temporary Global Note will be exchanged for the Regulation S Permanent Global Note upon the receipt by the Trustee of (A) a written certificate from the Depositary in the form
determined by the Company to be required pursuant to Rule 903 under the Securities Act, together with copies of certificates in the form determined by the Company to be required pursuant to Rule 903 under the Securities Act from Euroclear and
Clearstream certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent
of any beneficial owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in the 144A Global
Note), and (B) an Officers’ Certificate from the Company to the effect that such certificates are in the proper form. Following receipt of such certificates, beneficial interests in the Regulation S Temporary Global Note shall be exchanged
for beneficial interests in the Regulation S Permanent Global Note pursuant to the applicable procedures of the Security Custodian, the Depositary, Euroclear and/or Clearstream. Simultaneously with the authentication of the Regulation S Permanent
Global Note, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by
adjustments made on the records of the Security Custodian and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided, subject in each case to compliance with the applicable procedures of
the Security Custodian, the Depositary, Euroclear and/or Clearstream. 

  
 7 

 (b) Book-Entry Provisions. Each Global Note shall represent such of the Outstanding 2036 Notes as shall be
specified therein and each shall provide that it shall represent the aggregate amount of Outstanding 2036 Notes from time to time endorsed thereon and that the aggregate amount of Outstanding 2036 Notes represented thereby may from time to time be
reduced or increased, as appropriate, to reflect exchanges, redemptions or purchases of such 2036 Notes. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the principal amount of Outstanding 2036 Notes represented
thereby shall be made by the Security Custodian in accordance with the standing instructions and procedures existing among (i) the Depositary (and Euroclear or Clearstream in the case of a Regulation S Global Note) and (ii) the Security
Custodian. 
 Members of, or Participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any Global
Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) 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 (B) impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise
of the rights of a Holder of any 2036 Notes. 
 (c) Certificated Notes. Except as provided in this Section 206 or Section 207 hereof,
owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of Certificated Notes. 
 (i) A Global Note
deposited with the Depositary or with the Trustee as custodian for the Depositary pursuant to Section 206(a) shall be transferred to the beneficial owners thereof in the form of Certificated Notes in an aggregate principal amount equal to the
principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 207 hereof and (A) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such
Global Note, (B) at any time such Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by the Company within 90 days of such notice, or (C) the Company, in its
sole discretion and subject to the procedures of the Depositary, notifies the Trustee in writing that it elects to cause the issuance of Certificated Notes under the Indenture; provided that in no event shall the Regulation S Temporary Global Note
be exchanged by the Company for Certificated Notes prior to (x) the expiration of the Restricted Period and (y) the receipt by the Registrar of any certificates determined by the Company to be required pursuant to Rule 903 under the
Securities Act. 

  
 8 

 (ii) Any Global Note that is transferred to the beneficial owners thereof pursuant to this
Section 206 shall be surrendered by the Depositary to the Trustee at its office located in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 206 shall
be executed, authenticated and delivered only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any Certificated Note delivered in exchange for an interest
in a Global Note that is a Transfer Restricted Note shall, except as otherwise provided by Section 207(b)(i)(B), bear the Transfer Restricted Notes legend set forth in Section 207(b)(i)(A). 

(iii) Subject to the provisions of Section 207(b), the registered Holder of a Global Note may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the 2036 Notes. 

(iv) If any of the events specified in Section 206(c)(i) occurs, the Company shall promptly make available to the Trustee a reasonable supply
of Certificated Notes in definitive, fully registered form without interest coupons. 
 (v) If a Certificated Note issued pursuant to this
Section 206(c) is exchanged for another Certificated Note, such 2036 Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of: (A) Section 207(a)(iii) (including the certification and
other requirements set forth on the reverse of the 2036 Notes intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be, or are otherwise in compliance with the requirements of the Securities Act) and such
other procedures as may from time to time be adopted by the Company and (B) Section 207(b).

Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor; provided, however, that transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to,
or for the account or benefit of, a U.S. Person (other than an Initial Purchaser) prior to (x) the expiration of the Restricted Period and (y) the receipt by the Registrar of any certificates determined by the Company to be required

(ii) Notwithstanding any other provisions of the Indenture (other than the provisions set forth in Section 206(c)), a Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee

CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO IT. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. 

(B) Upon any sale or transfer of a Transfer Restricted Note (including any Transfer Restricted Note represented by a Global Note) pursuant to
Rule 144 under the Securities Act, the Security Registrar shall permit the Holder thereof to exchange such Transfer Restricted Note for a Certificated Note that does not bear the legend set forth above and rescind any restriction on the transfer of
such Transfer Restricted Note, if the Holder certifies in writing to the Security Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the 2036 Note). 

(ii) Global Notes Legend. Each Global Note shall bear a legend in substantially the following form: 

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY

                    , or registered assigns, the principal sum of

 (Reverse Side of Security) 

This Security is one of a duly authorized issue of Securities of the Company (the “Securities”), issued and issuable in one or more series under an
Indenture, dated as of August 16, 2000, as supplemented and amended to date, including without limitation by the Fifth Supplemental Indenture thereto dated as of October 27, 2006 (the “Indenture”), between the Company and The
Bank of New York (as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as Trustee (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, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities issued thereunder and of the terms upon
which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated as the 6.450% Notes due 2036 (the “2036 Notes”). Capitalized terms used herein for which no definitions are provided
herein shall have the meanings set forth in the Indenture. 
 The 2036 Notes shall be redeemable, in whole or in part at any time, at the option of the
Company on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2036 Notes to be redeemed and (ii) the sum of the present values of the principal amount of the 2036
Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined)
plus 25 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such Redemption Date. 
 “Comparable
Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (the “Remaining Life”) 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 with the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of two Reference Treasury Dealer Quotations for such Redemption
Date. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means each of J.P. Morgan Securities Inc. and Greenwich Capital Markets, Inc., and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer.

 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined
by the Trustee, of the bid 

  
 A-6 

 
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., The City of New York time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means, with respect to any
Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which
is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,”
for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

The Trustee shall initially serve as the principal Paying Agent with respect to the Securities of this series, and the principal Place of Payment shall
initially be at the office of the Paying Agent in the Borough of Manhattan, The City of New York. 
 Notice of any redemption by the Company will be mailed
at least 30 days but not more than 60 days before any Redemption Date to each Holder of the 2036 Notes to be redeemed. If less than all the 2036 Notes are to be redeemed at the option of the Company, the Trustee shall select, in such manner as it
shall deem fair and appropriate, the 2036 Notes to be redeemed in whole or in part. The Trustee may select for redemption the 2036 Notes and portions of the 2036 Notes in amounts of whole multiples of $1,000. 

If an Event of Default with respect to the 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, with the effect and subject to the conditions 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 all series affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Outstanding Securities of all series with respect to which a default under the Indenture shall have occurred and be continuing (voting as one 

  
 A-7 

 
class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such default under the Indenture and its consequences. The Indenture also permits the
Holders of not less than a majority in 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
affecting such series. 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 hereof 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 a majority 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 reasonable indemnity, 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 interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Securities of this series or of any Securities of this series
and for covenant defeasance at any time of certain covenants in the Indenture upon compliance with certain conditions set forth in the Indenture. 
 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. 
 The 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 of $2,000. As provided in the Indenture and subject to the limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series of like tenor of a different authorized denomination, as requested by the Holder surrendering the same upon surrender of the Security or Securities to be exchanged at
the office or agency of the Company. 

  
 A-8 

 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 any office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory
to the Company and the Security Registrar and duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and of like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 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. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT
TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

the Person entitled thereto as such address shall appear in the Security Register or (B) by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least
sixteen (16) days prior to the date for payment by the Person entitled thereto.

 (Reverse Side of Security) 

This Security is one of a duly authorized issue of Securities of the Company (the “Securities”), issued and issuable in one or more series under an
Indenture, dated as of August 16, 2000, as supplemented and amended to date, including without limitation by the Fifth Supplemental Indenture thereto dated as of October 27, 2006 (the “Indenture”), between the Company and The
Bank of New York (as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as Trustee (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, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities issued thereunder and of the terms upon
which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated as the 6.450% Notes due 2036 (the “2036 Notes”). Capitalized terms used herein for which no definitions are provided
herein shall have the meanings set forth in the Indenture. 
 The 2036 Notes shall be redeemable, in whole or in part at any time, at the option of the
Company on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2036 Notes to be redeemed and (ii) the sum of the present values of the principal amount of the 2036
Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined)
plus 25 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such Redemption Date. 
 “Comparable
Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (the “Remaining Life”) 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 with the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of two Reference Treasury Dealer Quotations for such Redemption
Date. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means each of J.P. Morgan Securities Inc. and Greenwich Capital Markets, Inc., and their respective successors;
provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer.

 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined
by the Trustee, of the bid 

  
 B-6 

 
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., The City of New York time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means, with respect to any
Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which
is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,”
for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

The Trustee shall initially serve as the principal Paying Agent with respect to the Securities of this series, and the principal Place of Payment shall
initially be at the office of the Paying Agent in the Borough of Manhattan, The City of New York. 
 Notice of any redemption by the Company will be mailed
at least 30 days but not more than 60 days before any Redemption Date to each Holder of the 2036 Notes to be redeemed. If less than all the 2036 Notes are to be redeemed at the option of the Company, the Trustee shall select, in such manner as it
shall deem fair and appropriate, the 2036 Notes to be redeemed in whole or in part. The Trustee may select for redemption the 2036 Notes and portions of the 2036 Notes in amounts of whole multiples of $1,000. 

If an Event of Default with respect to the 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, with the effect and subject to the conditions 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 all series affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Outstanding Securities of all series with respect to which a default under the Indenture shall have occurred and be continuing (voting as one 

  
 B-7 

 
class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such default under the Indenture and its consequences. The Indenture also permits the
Holders of not less than a majority in 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
affecting such series. 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 hereof 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 a majority 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 reasonable indemnity, 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 interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Securities of this series or of any Securities of this series
and for covenant defeasance at any time of certain covenants in the Indenture upon compliance with certain conditions set forth in the Indenture. 
 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. 
 The 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 of $2,000. As provided in the Indenture and subject to the limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series of like tenor of a different authorized denomination, as requested by the Holder surrendering the same upon surrender of the Security or Securities to be exchanged at
the office or agency of the Company. 

  
 B-8 

 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 any office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory
to the Company and the Security Registrar and duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and of like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 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. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT
TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
 This
Security shall be governed by, and construed in accordance with, the laws of the State of New York.

Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined)

successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury
Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

Notwithstanding Section 1104 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the
Redemption Price but only the manner of calculation thereof. 
 The Company shall notify the Trustee of the Redemption Price with respect to the foregoing
redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price. 
 If less than all of the
2037 Notes are to be redeemed, the Trustee shall select the 2037 Notes or portions of 2037 Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption 2037 Notes and portions of 2037

Global Note, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by
adjustments made on the records of the Security Custodian and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided, subject in each case to compliance with the applicable procedures of
the Security Custodian, the Depositary, Euroclear and/or Clearstream.

Custodian. 
 Members of, or Participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any Global
Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) 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 (B) impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise
of the rights of a Holder of any 2037 Notes.

owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of Certificated Notes.

principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.07 hereof and (A) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such
Global Note and a successor depositary is not appointed by the Company within 90 days of such notice, (B) at any time such Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not
appointed by the Company within 90 days after it becomes aware of such cessation, or (C) the Company, in its sole discretion and subject to the procedures of the Depositary, notifies the Trustee in writing that it elects to cause the issuance
of Certificated Notes under the Indenture; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Certificated Notes prior to (x) the expiration of the Restricted Period and (y) the receipt
by the Registrar of any certificates determined by the Company to be required pursuant to Rule 903 under the Securities Act. 

  
 8 

 (ii) Any Global Note that is transferred to the beneficial owners thereof pursuant to this
Section 2,06 shall be surrendered by the Depositary to the Trustee at its office located in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall
authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.06
shall be executed, authenticated and delivered only in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof and registered in such names as the Depositary shall direct. Any Certificated Note delivered in exchange for

Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the 2037 Notes. 

(iv) If any of the events specified in Section 2.06(c)(i) occurs, the Company shall promptly make available to the Trustee a reasonable supply
of Certificated Notes in definitive, fully registered form without interest coupons.

Section 2.06(c) is exchanged for another Certificated Note, such 2037 Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of: (A) Section 2.07(a)(iii) (including the certification
and other requirements set forth on the reverse of the 2037 Notes intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be, or are otherwise in compliance with the requirements of the Securities Act) and such

DCP Midstream, LLC (formerly known as Duke Energy Field Services, LLC), a limited liability company duly organized and existing under the laws of the State of
Delaware (the “Company,” which term includes any successor company under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to
                    , or registered assigns, the principal sum of

respective Interest Payment Dates. Interest payments for this Security shall be computed and paid on the basis of a 360-day year of twelve 30-day months, to the event

any such delay) with the same force and effect as if made on the date the payment was originally payable. “Business Day” means a day other than (i) a Saturday or a Sunday, (ii) a day on which banking institutions in the Place of

 (Reverse Side of Security) 

This Security is one of a duly authorized issue of Securities of the Company (the “Securities”), issued and issuable in one or more series under an
Indenture, dated as of August 16, 2000, as supplemented and amended to date, including without limitation by the Sixth Supplemental Indenture thereto dated as of September 17, 2007 (the “Indenture”), between the Company and The
Bank of New York (as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as Trustee (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, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities issued thereunder and of the terms upon
which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated as the 6.750% Notes due 2037 (the “2037 Notes”). Capitalized terms used herein for which no definitions are provided
herein shall have the meanings set forth in the Indenture. 
 The 2037 Notes shall be redeemable, in whole or in part at any time, at the option of the
Company on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2037 Notes to be redeemed and (ii) the sum of the present values of the principal amount of the 2037
Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined)
plus 35 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such Redemption Date. 
 “Comparable
Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (the “Remaining Life”) 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 with the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of three Reference Treasury Dealer Quotations for such
Redemption Date. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means each of Greenwich Capital Markets, Inc., Barclays Capital Inc., J.P. Morgan Securities Inc. and their respective
successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury
Dealer. 
 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Quotation Agent, of 

  
 A-6 

 
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 Quotation Agent by such Reference Treasury
Dealer at 5:00 p.m., The City of New York time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means, with respect
to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor
publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant
Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not published during
the week preceding the calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

The Trustee shall initially serve as the principal Paying Agent with respect to the Securities of this series, and the principal Place of Payment shall
initially be at the office of the Paying Agent in the Borough of Manhattan, The City of New York. 
 Notice of any redemption by the Company will be mailed
at least 30 days but not more than 60 days before any Redemption Date to each Holder of the 2037 Notes to be redeemed. If less than all the 2037 Notes are to be redeemed at the option of the Company, the Trustee shall select, in such manner as it
shall deem fair and appropriate, the 2037 Notes to be redeemed in whole or in part. The Trustee may select for redemption the 2037 Notes and portions of the 2037 Notes in amounts of whole multiples of $1,000. 

If an Event of Default with respect to the 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, with the effect and subject to the conditions 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 all series affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Outstanding Securities of all series with respect to which a default under the Indenture shall have occurred and be continuing (voting as one 

  
 A-7 

 
class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such default under the Indenture and its consequences. The Indenture also permits the
Holders of not less than a majority in 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
affecting such series. 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 hereof 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 a majority 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 reasonable indemnity, 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 interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Securities of this series or of any Securities of this series
and for covenant defeasance at any time of certain covenants in the Indenture upon compliance with certain conditions set forth in the Indenture. 
 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. 
 The 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 of $2,000. As provided in the Indenture and subject to the limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series of like tenor of a different authorized denomination, as requested by the Holder surrendering the same upon surrender of the Security or Securities to be exchanged at
the office or agency of the Company. 

  
 A-8 

 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 any office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory
to the Company and the Security Registrar and duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and of like tenor and for the same
aggregate principal amount, will be issued to the designated transferee or transferees. 
 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. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), IT
TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

DCP Midstream, LLC (formerly known as Duke Energy Field Services, LLC), a limited liability company duly organized and existing under the laws of the State of

York 10286, upon surrender of such Securities to the Paying Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (B) by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen
(16) days prior to the date for payment by the Person entitled thereto. 
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

 (Reverse Side of Security) 

This Security is one of a duly authorized issue of Securities of the Company (the “Securities”), issued and issuable in one or more series under an
Indenture, dated as of August 16, 2000, as supplemented and amended to date, including without limitation by the Sixth Supplemental Indenture thereto dated as of September 17, 2007 (the “Indenture”), between the Company and The
Bank of New York (as successor to JPMorgan Chase Bank, N.A., formerly known as The Chase Manhattan Bank), as Trustee (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, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities issued thereunder and of the terms upon
which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated as the 6.750% Notes due 2037 (the “2037 Notes”). Capitalized terms used herein for which no definitions are provided
herein shall have the meanings set forth in the Indenture. 
 The 2037 Notes shall be redeemable, in whole or in part at any time, at the option of the
Company on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2037 Notes to be redeemed and (ii) the sum of the present values of the principal amount of the 2037
Notes to be redeemed and the remaining scheduled payments of interest thereon (exclusive of interest accrued to the Redemption Date) from the Redemption Date to the respective scheduled payment dates discounted from their respective scheduled
payment dates to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined)
plus 35 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such Redemption Date. 
 “Comparable
Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the term between the Redemption Date and the Stated Maturity (the “Remaining Life”) 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 with the Remaining Life. 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of three Reference Treasury Dealer Quotations for such
Redemption Date. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means each of Greenwich Capital Markets, Inc., Barclays Capital Inc., J.P. Morgan Securities Inc, and their respective
successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury
Dealer. 
 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Quotation Agent, of 

  
 B-6 

 
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 Quotation Agent by such Reference Treasury
Dealer at 5:00 p.m., The City of New York time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate” means, with respect
to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor
publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant
Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, 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 (2) if such release (or any successor release) is not published during
the week preceding the calculation date or does not contain such yields, the rate per 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 the Redemption Date. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

The Trustee shall initially serve as the principal Paying Agent with respect to the Securities of this series, and the principal Place of Payment shall
initially be at the office of the Paying Agent in the Borough of Manhattan, The City of New York. 
 Notice of any redemption by the Company will be mailed
at least 30 days but not more than 60 days before any Redemption Date to each Holder of the 2037 Notes to be redeemed. If less than all the 2037 Notes are to be redeemed at the option of the Company, the Trustee shall select, in such manner as it
shall deem fair and appropriate, the 2037 Notes to be redeemed in whole or in part The Trustee may select for redemption the 2037 Notes and portions of the 2037 Notes in amounts of whole multiples of $1,000. 

If an Event of Default with respect to the 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, with the effect and subject to the conditions 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 all series affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Outstanding Securities of all series with respect to which a default under the Indenture shall have occurred and be continuing (voting as one 

  
 B-7 

 
class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such default under the Indenture and its consequences. The Indenture also permits the
Holders of not less than a majority in 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
affecting such series. 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 hereof 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 a majority 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 reasonable indemnity, 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 interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Securities of this series or of any Securities of this series
and for covenant defeasance at any time of certain covenants in the Indenture upon compliance with certain conditions set forth in the Indenture.

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.

series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. As provided in the Indenture and subject to the limitations therein set forth, Securities of this series are
exchangeable for a like aggregate principal amount of Securities of this series of like tenor of a different authorized denomination, as requested by the Holder surrendering the same upon surrender of the Security or Securities to be exchanged at
the office or agency of the Company. 

  
 B-8

aggregate principal amount, will be issued to the designated transferee or transferees. 
 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. 

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), IT
