 (FORM OF REVERSE OF SECURITY) 

 

	1.	INDENTURE 

 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 19, 2007, as supplemented and amended from time to
time (herein called the “Indenture”), among the Company, the Subsidiary Guarantors and The Bank of New York Mellon (as successor to The Bank of New York), 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, any Subsidiary
Guarantor and 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 U.S.$250,000,000; provided, however, that the Company may create and issue further securities ranking pari passu with the Securities in all respects or in all respects except for the payment of interest accruing prior to the
issue date of such further securities and except for the first payment of interest following the issue date of such further securities. The Company may consolidate such further securities with the Securities to form a single series, having the same
terms as to status, redemption or otherwise as the Securities. 
 All terms used in this Security that are defined in the
Indenture shall have the meaning assigned to them in the Indenture. 
  

	2.	OPTIONAL REDEMPTION 

 The
Securities of this series are redeemable only in accordance with the following provision: 
 (A) The Securities of this series
are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time, in whole or in part, at the election of the Company at a redemption price equal to:the greater of (a) 100% of the principal amount of the
Securities and (b) as determined by the Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on the Securities (not including any portion of the payment of
interest accrued as of the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Adjusted Treasury Rate, plus 50 basis points.

 “Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the
semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

 “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment
Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt of
comparable maturity to the remaining term of such Securities. 

  
 A-4

 “Comparable Treasury Price” means, with respect to any redemption date, the
average of the Reference Treasury Dealer Quotations for the redemption date. 
 “Independent Investment Banker”
means one of the Reference Treasury Dealers selected by the Company. 
 “Reference Treasury Dealer” means
(1) each of J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC and RBC Capital Markets, LLC (or their respective affiliates that are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the
foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute for it another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer
selected by the Trustee after consultation with the Company. 
 “Reference Treasury Dealer Quotation” means,
with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted by the Reference Treasury Dealer at 5:00 p.m. on the third business day preceding that redemption date. 
 In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof. 
 Installments of accrued and unpaid interest whose Stated Maturity is on or prior to the Redemption Date
will be payable to the Holders of the Securities of this series, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provision of the Indenture.

  

	3.	MANDATORY REDEMPTION 

 The
Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Securities. 
  

	4.	OFFER TO PURCHASE 

 If a
Change of Control occurs, unless the Company has exercised its right to redeem all of the Securities, then the Company shall offer to repurchase from each Holder all or any part (equal to U.S.$1,000 or an integral multiple thereof) of such
Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to but excluding the date of repurchase (subject to the right of Holders of record on the relevant Regular
Record Date to receive interest due on the relevant Interest Payment Date) as provided in, and subject to the terms of, the Indenture. 

  
 A-5

	5.	SATISFACTION, DISCHARGE AND DEFEASANCE 

 The Indenture contains provisions for satisfaction, discharge and defeasance of (a) the entire indebtedness on this Security and (b) certain restrictive covenants and the related Events of
Default, upon compliance by the Company with certain conditions set forth therein. 
  

	6.	DEFAULTS AND REMEDIES 

The Events of Default relating to the Securities of this series are set forth in the Indenture. If an Event of Default with respect to
Securities of this series shall occur and be continuing, an amount of principal, premium, if any, accrued but unpaid interest and any other monetary obligations of the Securities of this series may be declared due and payable in the manner and with
the effect provided in the Indenture. 
 If any Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then Outstanding Securities of this series by written notice to the Company (and to the Trustee if given by Holders) may declare the principal of, premium, if any, accrued but unpaid interest and any other
monetary obligations on all the then Outstanding Securities of this series to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all Outstanding
Securities of this series will automatically become due and payable immediately without further action or notice on part of the Trustee or any Holder. 
 Upon payment of the amount of principal so declared due and payable, of premium, if any, and of overdue interest (to the extent that the payment of such interest shall be legally enforceable), all of the
Company’s obligations in respect of the payment of the principal of, premium, if any, and interest, if any, on the Securities of this series shall terminate. 
  

	7.	AMENDMENTS AND WAIVERS 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
obligations of the Company, any Subsidiary Guarantor and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company, any Subsidiary Guarantor 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. Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of this series (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such series of Securities) may, on behalf of the Holders of all the Securities of this series, waive compliance with any term, provision, covenant
or condition of the Indenture, any Subsidiary Guarantee or the Securities of this series. Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of this series (including, without limitation, by consent
obtained in connection with a purchase of, or tender offer or exchange offer for, such series of Securities) may, on behalf of the Holders of all the Securities of this series, waive past defaults under certain covenants of the Indenture which
relate to this series. However, a default in the payment of the principal of, premium, if any, or interest on, any of the Securities of this series or relating to a provision which under the Indenture cannot be modified or amended without the
consent of the Holders of each Outstanding Security of this series affected cannot be so waived. 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. 

  
 A-6

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, 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 U.S.$2,000 and any integral of U.S.$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 of any authorized denomination, as requested by the Holder surrendering the same. 
 No service charge

 Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal

the other identification numbers placed thereon and any such notice shall not be affected by any defect in or omission of such numbers. 
  

	13.	NO RECOURSE AGAINST OTHERS 

No recourse under or upon any obligation, covenant or agreement contained in this Security, or because of any indebtedness evidenced
thereby, shall be had against any incorporator, as such or against any past, present or future shareholder, officer or director, as such, of the Company, any Subsidiary Guarantor or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the enforcement or any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the

 ELEVENTH SUPPLEMENTAL INDENTURE, dated as of August 23, 2012 (this
“Supplemental Indenture”), between Burlington Northern Santa Fe, LLC, a limited liability company duly formed and existing under the laws of the State of Delaware (as successor in interest to Burlington Northern Santa Fe
Corporation), having its principal office at 2650 Lou Menk Drive, Fort Worth, Texas 76131-2830 (the “Company”), and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.), a
national banking association, as successor in interest to J.P. Morgan Trust Company, National Association, as successor in interest to Bank One Trust Company, N.A., as successor in interest to The First National Bank of Chicago, as trustee, having a
corporate trust office at 601 Travis Street, 16th Floor, Houston, Texas 77002 (the “Trustee”). 
 WHEREAS, the
Company executed and delivered the indenture, dated as of December 1, 1995, to the Trustee, as supplemented by the Fifth Supplemental Indenture, dated as of February 11, 2010 (as heretofore supplemented, the “Indenture”),
to provide for the issuance of the Company’s debentures, notes or other evidences of indebtedness (the “Securities”), to be issued in one or more series; 
 WHEREAS, pursuant to the terms of the Indenture, the Company desires to provide for the establishment of two new series of Securities under the Indenture to be known as its “3.050% Debentures due
September 1, 2022” (the “2022 Debentures”) and “4.375% Debentures due September 1, 2042” (the “2042 Debentures” and, together with the 2022 Debentures, the “Debentures”),
the form and substance of each such series and the terms, provisions and conditions thereof to be set forth as provided in the Indenture and this Supplemental Indenture; 
 WHEREAS, the Board of Managers of the Company, pursuant to the resolutions duly adopted on March 1, 2011, January 24, 2012 and July 12, 2012, has duly authorized the issuance of the
2022 Debentures and the 2042 Debentures, and has authorized the proper officers of the Company to execute any and all appropriate documents necessary or appropriate to effect each such issuance; 

WHEREAS, this Supplemental Indenture is being entered into pursuant to the provisions of Section 901(7) of the Indenture;

 WHEREAS, the Company has requested that the Trustee execute and deliver this Supplemental Indenture; and 

WHEREAS, all things necessary to make this Supplemental Indenture a valid agreement of the Company, in accordance with its terms, and to
make each of the 2022 Debentures and the 2042 Debentures, each when executed by the Company and authenticated and delivered by the Trustee, the valid obligations of the Company, have been performed, and the execution and delivery of this
Supplemental Indenture has been duly authorized in all respects; 

 NOW THEREFORE, in consideration of the premises and the purchase and acceptance of each of
the 2022 Debentures and the 2042 Debentures by the Holders thereof, and for the purpose of setting forth, as provided in the Indenture, the forms and terms of each of the 2022 Debentures and the 2042 Debentures, the Company covenants and agrees with
the Trustee, as follows: 
 ARTICLE I 
 Definitions 
 SECTION 1.01. Definition of Terms. Unless the context
otherwise requires: 
 (a) each term defined in the Indenture has the same meaning when used in this Supplemental
Indenture; 
 (b) the singular includes the plural and vice versa; and 

(c) headings are for convenience of reference only and do not affect interpretation. 

ARTICLE II 

General Terms and Conditions of the 2022 Debentures 
 SECTION 2.01. Designation and Principal Amount. There is hereby authorized and established a series of Securities under the Indenture, designated as the “3.050% Debentures due
September 1, 2022”, which is not limited in aggregate principal amount. The aggregate principal amount of the 2022 Debentures to be issued shall be as set forth in any Company Order for the authentication and delivery of the 2022
Debentures, pursuant to Section 303 of the Indenture. 
 SECTION 2.02. Maturity. The Stated Maturity of principal
for the 2022 Debentures will be September 1, 2022. 
 SECTION 2.03. Further Issues. The Company may from time to
time, without the consent of the Holders of the 2022 Debentures, issue additional debentures of that series. Any such additional debentures will have the same ranking, interest rate, maturity date and other terms as the 2022 Debentures, except for
the issue date and, if applicable, the initial interest accrual date and the initial Interest Payment Date. Any such additional debentures, together with the 2022 Debentures herein provided for, will constitute a single series of Securities under
the Indenture. 
 SECTION 2.04. Form and Payment. Payment of the principal of (and premium, if any) and interest on the
2022 Debentures will be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

  
 2 

 SECTION 2.05. Global Securities. Upon the original issuance, the 2022 Debentures will
be represented by one or more Global Securities registered in the name of Cede & Co., the nominee of The Depository Trust Company (“DTC”). The Company will issue the 2022 Debentures in denominations of $2,000 and integral
multiples of $1,000 in excess thereof and will deposit the Global Securities with DTC or its custodian and register the Global Securities in the name of Cede & Co. DTC shall be the initial Depositary for the 2022 Debentures. 

SECTION 2.06. Definitive Form. If (a) (i) the Depositary is at any time unwilling or unable to continue as depositary
for the 2022 Debentures or (ii) the Depositary has ceased to be a clearing agency registered under the Exchange Act, and in either case a successor Depositary is not appointed by the Company within 90 days of notice thereof, (b) an Event
of Default has occurred with regard to the 2022 Debentures and has not been cured or waived, or (c) the Company at any time and in its sole discretion and subject to the procedures of the Depositary determines not to have the 2022 Debentures
represented by Global Securities, the Company may issue the 2022 Debentures in definitive form in exchange for such Global Securities. In any such instance, an owner of a beneficial interest in 2022 Debentures will be entitled to physical delivery
in definitive form of 2022 Debentures, equal in principal amount to such beneficial interest and to have 2022 Debentures registered in its name as shall be established in a Company Order. 

SECTION 2.07. Interest. The 2022 Debentures will bear interest (computed on the basis of a 360-day year consisting of twelve
30-day months) from August 23, 2012 at the rate of 3.050% per annum, payable semi-annually; interest payable on each Interest Payment Date will include interest accrued from August 23, 2012, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for; the Interest Payment Dates on which such interest shall be payable are March 1 and September 1, commencing on March 1, 2013; and the Regular Record Date for the interest
payable on any Interest Payment Date is the close of business on the February 15 or August 15, as the case may be, next preceding the relevant Interest Payment Date, whether or not that day is a Business Day. 

SECTION 2.08. Authorized Denominations. The 2022 Debentures shall be issuable in denominations of $2,000 and integral multiples of
$1,000 in excess thereof. 
 SECTION 2.09. Redemption. At any time before June 1, 2022, the 2022 Debentures are
subject to redemption upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2022
Debentures to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such interest accrued as of the Redemption Date) discounted to the Redemption
Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 20 basis points, plus in either case any accrued and unpaid interest thereon to the Redemption Date. The
Independent Investment Banker (as defined below) will calculate the Redemption Price. 

  
 3 

 At any time on or after June 1, 2022, the 2022 Debentures are subject to redemption
upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal amount of the 2022 Debentures to be redeemed plus accrued and unpaid
interest thereon to the Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date, the
rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming 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. 
 “Comparable Treasury Issue” means the United States Treasury security selected by the
Independent Investment Banker as having a maturity comparable to the remaining term of the 2022 Debentures that would be used, 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 term of the 2022 Debentures. 
 “Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if
the Independent Investment Banker 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 appointed by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m. on the third Business
Day preceding such Redemption Date. 
 “Reference Treasury Dealer” means each of Citigroup Global Markets Inc.,
Goldman, Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors and one other nationally recognized investment banking firm that is a primary U.S. Government securities dealer in New York
City (a “Primary Treasury Dealer”) specified from time to time by the Company; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company shall replace that former dealer with another
Primary Treasury Dealer. 

  
 4 

 Notice of any redemption will be mailed at least 30 days but not more than 60 days before
the Redemption Date to each Holder of the 2022 Debentures to be redeemed. Notwithstanding Section 1104 of the Indenture, such notice, if relating to a redemption under the first paragraph of this Section, need not set forth the Redemption Price
but only the manner of calculation thereof. The Company shall give the Trustee notice of such Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the
2022 Debentures or portions thereof called for redemption. 
 SECTION 2.10. Change of Control. (a) Upon the
occurrence of a Change of Control Repurchase Event, unless the Company has exercised its right to redeem all 2022 Debentures in accordance with the redemption terms as set forth in the 2022 Debentures by giving notice of such redemption to the
Holders of the 2022 Debentures pursuant to Section 1104 of the Indenture prior to the 30th day following the Change of Control Repurchase Event, the Company shall make an irrevocable offer to each Holder of 2022 Debentures to repurchase all or
any part (in integral multiples of $1,000) of such Holder’s 2022 Debentures at a repurchase price in cash equal to 101% of the aggregate principal amount of 2022 Debentures repurchased plus any accrued and unpaid interest on the 2022 Debentures
repurchased to, but not including, the date of repurchase (the “Repurchase Price”). 
 (b) Within 30 days
following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but in either case, after the public announcement of the transaction that constitutes or may constitute the Change of Control, the
Company shall mail to each Holder of 2022 Debentures, with a copy to the Trustee, a notice: 
 (i) describing the
transaction or transactions that constitute or may constitute the Change of Control Repurchase Event; 
 (ii)
offering to repurchase all 2022 Debentures tendered; 
 (iii) setting forth the payment date for the repurchase
of the 2022 Debentures, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Repurchase Date”); 

(iv) if mailed prior to the date of consummation of the Change of Control, stating that the offer to repurchase is
conditioned on a Change of Control Repurchase Event occurring on or prior to the Repurchase Date; 
 (v)
disclosing that any 2022 Debenture not tendered for repurchase will continue to accrue interest; and 
 (vi)
specifying the procedures for tendering 2022 Debentures. 

  
 5 

 (c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange
Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the 2022 Debentures as a result of a Change of Control Repurchase Event. To the extent that
the provisions of any securities laws or regulations conflict with the provisions of this Section 2.10, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under
this Section 2.10 by virtue of such conflict. 
 (d) On the Repurchase Date following a Change of Control Repurchase Event,
the Company shall, to the extent lawful: 
 (i) accept for payment all 2022 Debentures or portions thereof
properly tendered pursuant to such offer; 
 (ii) deposit with the Trustee an amount equal to the aggregate
Repurchase Price in respect of all 2022 Debentures or portions thereof properly tendered; and 
 (iii) deliver or
cause to be delivered to the Trustee the 2022 Debentures properly accepted, together with an Officers’ Certificate of the Company stating the aggregate principal amount of 2022 Debentures or portions thereof being repurchased by the Company.

 (e) The Trustee will promptly transmit to each Holder of 2022 Debentures properly tendered, the Repurchase Price for such 2022
Debentures, and the Trustee, upon the execution and delivery by the Company of such 2022 Debentures, will promptly authenticate and cause to be transferred by book-entry to each Holder a new 2022 Debenture equal in principal amount to any
unpurchased portion of any 2022 Debentures surrendered; provided that each new 2022 Debenture will be in a principal amount of a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof. 

(f) The Company shall not be required to make an offer to repurchase the 2022 Debentures upon a Change of Control Repurchase Event if a
third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all 2022 Debentures properly tendered and not withdrawn under its offer.

 (g) Solely for purposes of this Section 2.10 in connection with the 2022 Debentures, the following terms shall have the
following meanings: 
 “Below Investment Grade Ratings Event” means that on any day within the 60-day period
(which period shall be extended so long as the rating of the 2022 Debentures is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (i) the occurrence of a Change of Control; or
(ii) public notice of the occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the 2022 Debentures are rated below Investment Grade by each of the Rating Agencies. Notwithstanding the foregoing, a
Below Investment Grade Ratings Event otherwise arising by virtue of a particular reduction in 

  
 6 

 
rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Ratings Event for purposes of the definition of
Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing that the reduction was the

reduction).

category of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor ratings category of S&P); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by
the Company.

Section 3(a)(62) of the Exchange Act, selected by the Company (as certified by a written consent or resolution of the Company’s board of managers) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

 SECTION 3.01. Designation and Principal Amount. There is hereby authorized and established a series of Securities
under the Indenture, designated as the “4.375% Debentures due September 1, 2042”, which is not limited in aggregate principal amount. The aggregate principal amount of the 2042 Debentures to be issued shall be as set forth in any

SECTION 3.02. Maturity. The Stated Maturity of principal for the 2042 Debentures will be September 1, 2042. 

SECTION 3.03. Further Issues. The Company may from time to time, without the consent of the Holders of the 2042 Debentures, issue
additional debentures of that series. Any such additional debentures will have the same ranking, interest rate, maturity date and other terms as the 2042 Debentures, except for the issue date and, if applicable, the initial interest accrual date and
the initial Interest Payment Date. Any such additional debentures, together with the 2042 Debentures herein provided for, will constitute a single series of Securities under the Indenture. 

SECTION 3.04. Form and Payment. Payment of the principal of (and premium, if any) and interest on the 2042 Debentures will be made
at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 

SECTION 3.05. Global Securities. Upon the original issuance, the 2042 Debentures will be represented by one or more Global
Securities registered in the name of Cede & Co., the nominee of The Depository Trust Company (“DTC”). The Company will issue the 2042 Debentures in denominations of $2,000 and integral multiples of $1,000 in excess thereof
and will deposit the Global Securities with DTC or its custodian and register the Global Securities in the name of Cede & Co. DTC shall be the initial Depositary for the 2042 Debentures. 

SECTION 3.06. Definitive Form. If (a) (i) the Depositary is at any time unwilling or unable to continue as depositary
for the 2042 Debentures or (ii) the Depositary has ceased to be a clearing agency registered under the Exchange Act, and in either case a successor Depositary is not appointed by the Company within 90 days of

  
 8 

 
notice thereof, (b) an Event of Default has occurred with regard to the 2042 Debentures and has not been cured or waived, or (c) the Company at any time and in its sole discretion and
subject to the procedures of the Depositary determines not to have the 2042 Debentures represented by Global Securities, the Company may issue the 2042 Debentures in definitive form in exchange for such Global Securities. In any such instance, an
owner of a beneficial interest in 2042 Debentures will be entitled to physical delivery in definitive form of 2042 Debentures, equal in principal amount to such beneficial interest and to have 2042 Debentures registered in its name as shall be
established in a Company Order. 
 SECTION 3.07. Interest. The 2042 Debentures will bear interest (computed on the basis
of a 360-day year consisting of twelve 30-day months) from August 23, 2012 at the rate of 4.375% per annum, payable semi-annually; interest payable on each Interest Payment Date will include interest accrued from August 23, 2012, or
from the most recent Interest Payment Date to which interest has been paid or duly provided for; the Interest Payment Dates on which such interest shall be payable are March 1 and September 1, commencing on March 1, 2013; and the
Regular Record Date for the interest payable on any Interest Payment Date is the close of business on the February 15 or August 15, as the case may be, next preceding the relevant Interest Payment Date, whether or not that day is a
Business Day. 
 SECTION 3.08. Authorized Denominations. The 2042 Debentures shall be issuable in denominations of $2,000
and integral multiples of $1,000 in excess thereof. 
 SECTION 3.09. Redemption. At any time before March 1, 2042,
the 2042 Debentures are subject to redemption upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal
amount of the 2042 Debentures to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such interest accrued as of the Redemption Date) discounted
to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus in either case any accrued and unpaid interest thereon to the Redemption
Date. The Independent Investment Banker (as defined below) will calculate the Redemption Price. 
 At any time on or after
March 1, 2042, the 2042 Debentures are subject to redemption upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal
amount of the 2042 Debentures to be redeemed plus accrued and unpaid interest thereon to the Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield
to maturity of the Comparable Treasury Issue, assuming 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. 

  
 9 

 “Comparable Treasury Issue” means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the 2042 Debentures that would be used, 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 term of the 2042 Debentures. 
 “Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if
the Independent Investment Banker 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 appointed by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m. on the third Business
Day preceding such Redemption Date. 
 “Reference Treasury Dealer” means each of Citigroup Global Markets Inc.,
Goldman, Sachs & Co. and Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors and one other nationally recognized investment banking firm that is a primary U.S. Government securities dealer in New York
City (a “Primary Treasury Dealer”) specified from time to time by the Company; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company shall replace that former dealer with another
Primary Treasury Dealer. 
 Notice of any redemption will be mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of the 2042 Debentures to be redeemed. Notwithstanding Section 1104 of the Indenture, such notice, if relating to a redemption under the first paragraph of this Section, need not set forth the Redemption Price but
only the manner of calculation thereof. The Company shall give the Trustee notice of such Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the
2042 Debentures or portions thereof called for redemption. 
 SECTION 3.10. Change of Control. (a) Upon the
occurrence of a Change of Control Repurchase Event, unless the Company has exercised its right to redeem all 2042 Debentures in accordance with the redemption terms as set forth in the 2042 Debentures by giving notice of such redemption to the
Holders of the 2042 Debentures pursuant to Section 1104 of the Indenture prior to the 30th day following the 

  
 10 

 
Change of Control Repurchase Event, the Company shall make an irrevocable offer to each Holder of 2042 Debentures to repurchase all or any part (in integral multiples of $1,000) of such
Holder’s 2042 Debentures at a repurchase price in cash equal to 101% of the aggregate principal amount of 2042 Debentures repurchased plus any accrued and unpaid interest on the 2042 Debentures repurchased to, but not including, the date of
repurchase (the “Repurchase Price”). 
 (b) Within 30 days following any Change of Control Repurchase Event or,
at the Company’s option, prior to any Change of Control, but in either case, after the public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall mail to each Holder of 2042 Debentures,
with a copy to the Trustee, a notice: 
 (i) describing the transaction or transactions that constitute or may
constitute the Change of Control Repurchase Event; 
 (ii) offering to repurchase all 2042 Debentures tendered;

 (iii) setting forth the payment date for the repurchase of the 2042 Debentures, which date will be no earlier
than 30 days and no later than 60 days from the date such notice is mailed (the “Repurchase Date”); 
 (iv) if mailed prior to the date of consummation of the Change of Control, stating that the offer to repurchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the
Repurchase Date; 
 (v) disclosing that any 2042 Debenture not tendered for repurchase will continue to accrue
interest; and 
 (vi) specifying the procedures for tendering 2042 Debentures. 

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the 2042 Debentures as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 3.10, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.10 by virtue of such
conflict. 
 (d) On the Repurchase Date following a Change of Control Repurchase Event, the Company shall, to the extent lawful:

 (i) accept for payment all 2042 Debentures or portions thereof properly tendered pursuant to such offer;

  
 11 

 (ii) deposit with the Trustee an amount equal to the aggregate Repurchase
Price in respect of all 2042 Debentures or portions thereof properly tendered; and 
 (iii) deliver or cause to
be delivered to the Trustee the 2042 Debentures properly accepted, together with an Officers’ Certificate of the Company stating the aggregate principal amount of 2042 Debentures or portions thereof being repurchased by the Company. 

(e) The Trustee will promptly transmit to each Holder of 2042 Debentures properly tendered, the Repurchase Price for such 2042 Debentures,
and the Trustee, upon the execution and delivery by the Company of such 2042 Debentures, will promptly authenticate and cause to be transferred by book-entry to each Holder a new 2042 Debenture equal in principal amount to any unpurchased portion of
any 2042 Debentures surrendered; provided that each new 2042 Debenture will be in a principal amount of a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof. 

(f) The Company shall not be required to make an offer to repurchase the 2042 Debentures upon a Change of Control Repurchase Event if a
third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all 2042 Debentures properly tendered and not withdrawn under its offer.

 (g) Solely for purposes of this Section 3.10 in connection with the 2042 Debentures, the following terms shall have the
following meanings: 
 “Below Investment Grade Ratings Event” means that on any day within the 60-day period
(which period shall be extended so long as the rating of the 2042 Debentures is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (i) the occurrence of a Change of Control; or
(ii) public notice of the occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the 2042 Debentures are rated below Investment Grade by each of the Rating Agencies. Notwithstanding the foregoing, a
Below Investment Grade Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Ratings
Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in
writing that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have
occurred at the time of such ratings reduction).

known as The Bank of New York Trust Company, N.A.), as successor to J.P. Morgan Trust Company, National Association, as successor in interest to Bank One Trust Company, N.A., as successor to The First National Bank of Chicago, as Trustee (herein
called the “Trustee”, which term includes any successor trustee under the Indenture), as supplemented by the Eleventh Supplemental Indenture, dated as of August 23, 2012, between the Company and the Trustee (herein called the
“Indenture”, which term shall have the meaning assigned to it in such instrument), 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, initially limited in the
aggregate principal amount of $600,000,000. The Company may, without the consent of the Holders of the Securities of this series, issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms
and conditions and with the same CUSIP number as this Security, except as provided in said Eleventh Supplemental Indenture. 

At any time before June 1, 2022, the Securities of this series are subject to redemption upon not less than 30 and not more than 60
days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed or (ii) the sum of the present
values of the remaining scheduled payments of principal and interest thereon (not including any portion of such interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate (as defined in said Eleventh Supplemental Indenture), plus 20 basis points, plus in either case any accrued and unpaid interest thereon to the Redemption Date. The Independent Investment Banker (as
defined in said Eleventh Supplemental Indenture) will calculate the Redemption Price. 
 At any time on or after June 1,
2022, the Securities of this series are subject to redemption upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal amount of
the Securities of this series to be redeemed plus accrued and unpaid interest thereon to 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 Holder, upon the cancellation hereof. 

 Upon the occurrence of a Change of Control Repurchase Event (as defined in said Eleventh
Supplemental Indenture), unless the Company has exercised its right of redemption as described above by giving notice of such redemption to the Holders of the Securities of this series pursuant to Section 1104 of the Indenture prior to the 30th
day following the Change of Control Repurchase Event, each Holder of Securities of this series shall have the right to require the Company to repurchase all or any part (in integral multiples of $1,000) of such Holder’s Securities pursuant to
the Change of Control notice as provided in, and subject to the terms of, said Eleventh Supplemental Indenture at a purchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus accrued and
unpaid interest, if any, to, but not including, the date of repurchase. 
 The Indenture contains provisions for defeasance at
any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this
series may be declared 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 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 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 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
the Trustee 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 (or in the case of a redemption on or after the Redemption Date). 

  
 2 

 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 of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject
to certain limitations therein set forth, 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 neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 All
terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

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 December 1, 1995, between the Company, as successor in interest to Burlington Northern Santa Fe Corporation, and The Bank of New York Mellon Trust Company, N.A. (formerly
known as The Bank of New York Trust Company, N.A.), as successor to J.P. Morgan Trust Company, National Association, as successor in interest to Bank One Trust Company, N.A., as successor to The First National Bank of Chicago, as Trustee (herein
called the “Trustee”, which term includes any successor trustee under the Indenture), as supplemented by the Eleventh Supplemental Indenture, dated as of August 23, 2012, between the Company and the Trustee (herein called the
“Indenture”, which term shall have the meaning assigned to it in such instrument), 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, initially limited in the
aggregate principal amount of $650,000,000. The Company may, without the consent of the Holders of the Securities of this series, issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms
and conditions and with the same CUSIP number as this Security, except as provided in said Eleventh Supplemental Indenture. 

At any time before March 1, 2042, the Securities of this series are subject to redemption upon not less than 30 and not more than 60
days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed or (ii) the sum of the present
values of the remaining scheduled payments of principal and interest thereon (not including any portion of such interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate (as defined in said Eleventh Supplemental Indenture), plus 25 basis points, plus in either case any accrued and unpaid interest thereon to the Redemption Date. The Independent Investment Banker (as
defined in said Eleventh Supplemental Indenture) will calculate the Redemption Price. 
 At any time on or after March 1,
2042, the Securities of this series are subject to redemption upon not less than 30 and not more than 60 days’ notice by mail, as a whole or in part, at the election of the Company, at a Redemption Price equal to 100% of the principal amount of
the Securities of this series to be redeemed plus accrued and unpaid interest thereon to 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 Holder, upon the cancellation hereof. 

 Upon the occurrence of a Change of Control Repurchase Event (as defined in said Eleventh
Supplemental Indenture), unless the Company has exercised its right of redemption as described above by giving notice of such redemption to the Holders of the Securities of this series pursuant to Section 1104 of the Indenture prior to the 30th
day following the Change of Control Repurchase Event, each Holder of Securities of this series shall have the right to require the Company to repurchase all or any part (in integral multiples of $1,000) of such Holder’s Securities pursuant to
the Change of Control notice as provided in, and subject to the terms of, said Eleventh Supplemental Indenture at a purchase price in cash equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus accrued and
unpaid interest, if any, to, but not including, the date of repurchase. 
 The Indenture contains provisions for defeasance at
any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this
series may be declared 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 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 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 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
the Trustee shall have failed to institute any such proceeding, for 60 

  
 2 

 
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 (or in the case of a redemption on or after the Redemption Date). 
 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 of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject
to certain limitations therein set forth, 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 neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
