 THIRD SUPPLEMENTAL INDENTURE dated as of June 3, 2016 (this “Third

WHEREAS, the Company executed and delivered the indenture, dated as of June 2, 2015, to the Trustee (the “Base
Indenture” and, as hereby amended by this Third Supplemental Indenture, the “Indenture”), to provide for the issuance of the Company’s unsubordinated and unsecured debt securities to be issued in one or more series;

 WHEREAS, pursuant to the terms of the Base Indenture, the Company desires to provide for the establishment of a new series of
Securities under the Base Indenture to be known as its “2.900% Senior Notes due 2026” (the “Notes”), the form and substance and the terms, provisions and conditions thereof to be set forth as provided in the Base Indenture
and this Third Supplemental Indenture; 
 WHEREAS, the execution and delivery of this Third Supplemental Indenture and the
issuance of the Notes have been authorized by a Board Resolution and the Board of Directors has authorized the proper officers of the Company to execute and deliver any and all appropriate documents necessary or appropriate to effect such issuance;
 
 WHEREAS, this Third Supplemental Indenture is being entered into pursuant to the provisions of Section 9.01 of the
Base Indenture; 
 WHEREAS, the Company has requested that the Trustee execute and deliver this Third Supplemental Indenture;
and 
 WHEREAS, all things necessary to make this Third Supplemental Indenture a valid agreement of the Company and the Trustee, in
accordance with its terms, and to make the Notes, 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 Third Supplemental
Indenture has been duly authorized in all respects; 
 NOW THEREFORE, in consideration of the premises and the purchase and
acceptance of the Notes by the Holders thereof and other valuable consideration receipt of which is hereby acknowledged by the Company, and for the purpose of setting forth, as provided in the Base Indenture, the form, terms and conditions of the
Notes, the Company covenants and agrees with the Trustee for the benefit of the Holders of the Notes, as follows: 

 ARTICLE I 

Definitions 
 SECTION 1.01.
Definitions. Unless the context otherwise requires, capitalized terms used but not defined herein or in the recitals above have the respective meanings set forth in the Base Indenture. The following additional terms are hereby established for
purposes of this Third Supplemental Indenture and shall have the meaning set forth in this Third Supplemental Indenture only for purposes of this Third Supplemental Indenture. 

“Notes” has the meaning set forth in the recitals above. 

“Below Investment Grade Ratings Event” means, with respect to the Notes, on any day within the 60-day period (which period
shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any Rating Agency) after the earlier of (1) the occurrence of a Change of Control; or (2) public notice of the
occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Notes are rated below investment grade by each and every Rating Agency. 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 at the Company’s request
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 the Below Investment Grade Ratings Event). 
 “Change of Control” means the consummation of any transaction
(including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Securities Exchange Act of 1934 (the “Exchange
Act”)), other than the Company or its subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company’s
Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed measured by voting power rather than number of shares. 

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Ratings
Event with respect to the Notes. 
 “DTC” means The Depository Trust Company. 

“Global Note” means a Security evidencing all or a part of a series of Securities, issued to the Depositary for such series
in accordance with Section 2.12 of the Base Indenture. 

  
 2 

 “Interest Payment Date” means, with respect to the payment of interest on the
Notes, June 15 and December 15 of each year. 
 “investment grade” means, with respect to Moody’s, a rating
of Baa3 or better (or its equivalent under any successor rating categories of Moody’s); with respect to S&P, a rating of BBB- or better (or its equivalent under any successor rating categories of S&P); and, with respect to any
additional Rating Agency or Rating Agencies selected by the Company, the equivalent investment grade credit rating. 

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors. 

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to
rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the
Exchange Act, selected by the Company (as certified by a Board Resolution) as a replacement agency for Moody’s or S&P, or both of them, as the case may be. 

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and its
successors. 
 “Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the
Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 

The words “herein,” “hereof,” and “hereunder” and other words of similar import refer to this Third Supplemental
Indenture as a whole and not to any particular Article, Section or other subdivision. The rules of construction set forth in Section 1.04 of the Base Indenture shall apply to this Third Supplemental Indenture. 

ARTICLE II

Establishment of the Notes 

SECTION 2.01. Designation and Establishment. Pursuant to the terms hereof and Section 2.01 of the Base Indenture, the Company
hereby establishes a new series of Securities designated as the “2.900% Senior Notes due 2026.” The series of Notes may be reopened, from time to time, for issuances of additional Securities of such series. Any such additional Securities
shall have the same ranking, interest rate, Stated Maturity and other terms as the Notes (other than the issue date, issue price and payment of interest accruing prior to the issue date of such additional Securities). Any such additional Securities,
together with the Notes herein provided for, shall constitute a single series of Securities under the Indenture. 
 SECTION 2.02. Form of
the Notes. The Notes shall be issued in substantially the form set forth in Exhibit A hereto. 

  
 3 

 SECTION 2.03. Principal Amount of the Notes. The Notes shall be initially issued in an
aggregate principal amount of $600,000,000. 
 SECTION 2.04. Interest Rates; Stated Maturity. The Notes issued pursuant to this Third
Supplemental Indenture shall bear interest (computed on the basis of a 360-day year consisting of twelve 30-day months) from June 3, 2016 at the rate of 2.900% per annum payable semiannually in arrears; interest payable on each Interest
Payment Date shall include interest accrued from June 3, 2016, or from the most recent date to which interest has been paid or duly provided for; the Interest Payment Dates on which such interest shall be payable are June 15 and
December 15, commencing on December 15, 2016; and the record date for the interest payable on any Interest Payment Date is the close of business on the June 1 or December 1, as the case may be, next preceding the relevant
Interest Payment Date. The Notes shall have a Stated Maturity of June 15, 2026. 
 SECTION 2.05. No Sinking Fund. No sinking
fund is provided for the Notes. 
 SECTION 2.06. Global Notes and Denomination of the Notes. Upon the original issuance, the Notes
shall be represented by one or more Global Notes. The Company shall issue the Notes in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof and shall deposit the Global Notes with the Trustee as Custodian for DTC in
New York, New York, and register the Global Notes in the name of DTC or its nominee. 
 SECTION 2.07. Optional Redemption. The Notes
are subject to redemption at the option of the Company as set forth in the form of Note attached hereto as Exhibit A. 
 SECTION
2.08. Change of Control Repurchase Event. (a) If a Change of Control Repurchase Event occurs with respect to the Notes, unless the Company has exercised its right to redeem the Notes pursuant to paragraph 5 of the Notes, the Company will
make an offer to each Holder of Notes to repurchase all or any part (in integral multiples of $1,000) of that Holder’s Notes at a repurchase price (the “Repurchase Price”) in cash equal to 101% of the aggregate principal amount
of such Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the Repurchase Date (defined below). Within 30 days following a Change of Control Repurchase Event or, at the Company’s option, prior
to a Change of Control, but after the public announcement of a Change of Control, the Company will mail, or cause to be mailed, a notice to each Holder of Notes, with a copy to the Trustee, describing the transaction or transactions that constitute
or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the payment date specified in the notice (such offer the “Repurchase Offer” and such date the “Repurchase Date”),
which Repurchase Date will be a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the
Repurchase Offer is conditioned on a Change of Control Repurchase Event occurring on or prior to the Repurchase Date. 
 (b) The Company will
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 Notes as a result of a
Change of Control Repurchase Event. To the extent that the provisions of any securities laws or 

  
 4 

 
regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

(3) deliver, or cause to be delivered, to the Trustee the Notes properly accepted, together with an Officers’ Certificate
stating the aggregate principal amount of Notes being repurchased by the Company pursuant to the Repurchase Offer and that all conditions precedent to the repurchase by the Company of Notes pursuant to the Repurchase Offer have been complied with.

 (d) The Trustee will promptly mail, or cause the Paying Agent to promptly mail, to each Holder of Notes, or portions of Notes, properly
tendered the Repurchase Price for such Notes, or portions of Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any
Notes surrendered, as applicable; provided that each new Note will be in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof. 

(e) The Company will not be required to make a Repurchase Offer 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 such an offer made by the Company and such third party purchases all Notes or portions of Notes properly tendered and not withdrawn under its offer.

 [FORM OF REVERSE SIDE OF INITIAL GLOBAL NOTE] 

2.900% Senior Note due 2026 
 1. Interest

 NORFOLK SOUTHERN CORPORATION, a Virginia corporation (such corporation, and its successors and assigns under the Indenture
hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will pay interest semiannually in arrears on June 15 and
December 15 of each year, commencing December 15, 2016. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 3, 2016. Interest shall be computed on the
basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate per annum borne by the Notes, and it shall pay interest on overdue installments of interest at the rate per annum borne by the Notes to
the extent lawful. 
 2. Method of Payment 

The Company will pay interest on the Notes (except defaulted interest) to the Persons who are Holders at the close of business on the
June 1 or December 1, as the case may be, next preceding the Interest Payment Date even if Notes are canceled after the record date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a
Global Note (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company will make all payments in respect of a definitive Note (including
principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes may also be made, in the case of a Holder of at least $1,000,000 aggregate
principal amount of Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 

3. Paying Agent and Registrar 
 Initially,
U.S. Bank National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice. The Company or any of its
domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 
 4. Indenture 

The Company issued the Notes under a Base Indenture, dated as of June 2, 2015, as supplemented by the Third Supplemental Indenture, dated
as of June 3, 2016 (together the 

 “Indenture”), between the Company and the Trustee. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”).
Terms defined in the Indenture and not defined in the Notes have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms. 

The Notes are unsubordinated, unsecured obligations of the Company. This Note is one of the Notes referred to in the Indenture initially
issued in an aggregate principal amount of $600,000,000. The Notes include such $600,000,000 aggregate principal amount of Notes and an unlimited aggregate principal amount of additional Notes that may be issued under the Indenture. Such Notes and
such additional Notes will be treated as a single series and class of Securities under the Indenture. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to create or incur Liens, the Restricted
Subsidiaries to create or incur Funded Debt and the Company to consolidate or merge with or into any other Person or sell, transfer, assign, lease, convey or otherwise dispose of all or substantially all of its assets to any Person. 

5. Optional Redemption 
 The Notes will be
redeemable as a whole at any time or in part from time to time, at the option of the Company as set forth in this paragraph 5. If the Notes are redeemed prior to the date that is three months prior to the Stated Maturity of the Notes, the Redemption
Price of the Notes to be redeemed will be equal to the greater of (i) 100% of the principal amount of such Notes or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of
interest accrued to, but not including, the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 20 basis points, plus in each case accrued
and unpaid interest on the principal amount being redeemed to, but not including, the Redemption Date. 
 If the Notes are redeemed on or
after the date that is three months prior to the Stated Maturity, the Redemption Price for the Notes to be redeemed will equal 100% of the principal amount of such Notes, plus accrued and unpaid interest to, but not including, the Redemption Date.

 “Treasury Yield” 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 will be determined and the Treasury Yield will 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 

  
 2 

 
date or does not contain such yields, the rate per annum equal to the semi-annual 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 of such Redemption Date. The Treasury Yield will be calculated on the third Business Day preceding the Redemption Date. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having
a maturity most comparable to the remaining term of the Notes 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 a maturity comparable to the
remaining term of the Notes. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by
the Company. 
 “Comparable Treasury Price” means (A) the average of five Reference Treasury Dealer Quotations for
such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (B) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such
quotations. 
 “Reference Treasury Dealer” means each of (i) Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Goldman, Sachs & Co. and Morgan Stanley & Co. LLC; and (ii) two other primary U.S. Government securities dealers in New York, New York (“Primary Treasury Dealers”) appointed by the Company and their
respective successors; provided, however, that if any of the foregoing ceases to be a Primary Treasury Dealer or otherwise fails to provide a Reference Treasury Dealer Quotation, the Company will substitute therefor another Primary Treasury Dealer.

 “Reference Treasury Dealer Quotation” means a quotation for a Comparable Treasury Issue provided by a Reference Treasury
Dealer. 
 6. Sinking Fund 
 The Notes
are not subject to any sinking fund. 
 7. Notice of Redemption 

Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date to each
Holder of Notes to be redeemed at his or her registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000. If the Company deposits with the Paying Agent money sufficient to pay the
Redemption Price of and accrued interest on all Notes (or portions thereof) to be redeemed on the Redemption Date by 10:00 a.m. New York City time on the Redemption Date and certain other conditions are satisfied, on and after such Redemption Date
interest ceases to accrue on such Notes (or such portions thereof) called for redemption. 

  
 3 

 8. Denominations; Transfer; Exchange 

The Notes are in registered form without coupons in minimum denominations of $2,000 and whole multiples of $1,000 in excess thereof. A Holder
may transfer or exchange Notes in accordance with the Indenture. Upon any transfer or exchange, the Company may require a Holder to cover any transfer tax or similar governmental charge payable in connection therewith. The Registrar need not
register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or to issue, register the transfer of or exchange any Notes for a period of
15 Business Days prior to the mailing of a notice of redemption of Notes to be redeemed. 
 9. Persons Deemed Owners 

The Holder of this Note may be treated as the owner of it for all purposes. 

10. Unclaimed Money 
 If money for the
payment of principal, premium, if any, or interest remains unclaimed for two years after such amount has become due and payable, the Trustee or Paying Agent shall pay the money back to the Company at its written request unless an applicable
abandoned property law designates another Person to receive such money. After any such payment, Holders entitled to the money must look only to the Company, and not to the Trustee or Paying Agent, for payment. 

11. Discharge; Defeasance 
 Subject to
certain conditions, the Company at any time may terminate certain or all of its Obligations under the Notes and the Indenture if the Company deposits with the Trustee money, U.S. Government Obligations or a combination thereof sufficient to pay and
discharge each installment of principal of, premium, if any, and interest on the Notes on the dates such installments of interest or principal and premium are due. The Company may also satisfy and discharge the Indenture by delivering to the Trustee
for cancellation all Notes that have theretofore been authenticated and delivered, subject to certain conditions. 
 12. Amendment, Waiver 

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in
principal amount of the Outstanding Notes affected, to amend or supplement the Indenture; provided, however, that no such amendment or supplement shall without the consent of each Holder of Notes (i) reduce the amount of Notes
whose Holders must consent to an amendment, supplement or waiver; (ii) reduce the rate of interest on any Notes; (iii) reduce the principal amount of or the premium, if any, on any Notes or change the Stated Maturity of any Notes;
(iv) change the place, manner, timing or Currency of payment of principal of, premium, if any, or interest on any Notes; or (v) make any change in the amendment and waiver provisions. The Indenture also contains provisions permitting the
Holders of not less than a majority in principal amount of the Outstanding Notes affected thereby, on behalf of all of the Holders of Notes, to waive compliance by the Company with any provision of the Indenture or the Notes, provided that
such waiver shall not affect the above provisions (i) – (v). 

  
 4 

 13. Defaults and Remedies 

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then
Outstanding, by a notice in writing to the Company (and to the Trustee if given by Holders), may declare the unpaid principal of (premium, if any) and accrued interest on, if any, Notes to be immediately due and payable. Certain events of bankruptcy
or insolvency are Events of Default. 
 Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The
Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes may direct the Trustee in its
exercise of any trust or power under the Indenture. The Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Company and the Trustee, may rescind and annul any declaration of acceleration and
its consequences if the Company has paid or deposited with the Trustee a sufficient sum under the Indenture and all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that has become due solely by
such declaration of acceleration, have been cured or waived. 
 14. Trustee Dealings with the Company 

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

15. No Recourse Against Others 
 A
director, officer, employee or stockholder of the Company or the Trustee, as such, shall not have any liability for any Obligations of the Company under the Notes or for any Obligations of the Company or the Trustee under the Indenture or for any
claim based on, in respect of or by reason of such Obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. 

16. Successors 
 Subject to certain
exceptions set forth in the Indenture, when a successor assumes all the Obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those Obligations.

and a successor depositary has not been appointed by the Corporation within 90 days of receipt by the Corporation of such notification, (B) if at any time the depositary ceases to be a clearing agency registered under the Exchange Act at a time
when the depositary is required to be so registered to act as such depositary and no successor depositary shall have been appointed by the Corporation within 90 days after it became aware of such cessation, (C) the Corporation, in its sole
discretion, executes and delivers to the Trustee a written order signed in the name of the Corporation by its Chairman of the Board, its President or a Vice President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant
Secretary to the effect that such Global Security, together with all other Global Securities of the same series, shall be exchangeable as described below, or (D) an event of default (as defined in Section 1.02 of the Indenture) has occurred and
is continuing with respect to the Series TT Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur, the beneficial owners of interests in the relevant Global Securities will be entitled to exchange those
interests for definitive bonds and, without unnecessary delay but in any event not later than the earliest date on which those interests may be so exchanged, the Corporation will deliver to the Trustee definitive bonds in such form and denominations
as are required by or pursuant to the Indenture, and of the same series, containing identical terms and in an aggregate principal amount equal to the principal amount of such Global Securities, such bonds to be duly executed by the Corporation. On
or after the earliest date on which such beneficial interests may be so exchanged, such Global Securities shall be surrendered from time to time by the depositary as shall be specified in the order from the Corporation with respect thereto (which
the Corporation agrees to deliver), and in accordance with any instructions given to the Trustee and the depositary (which instructions shall be in writing but need not be contained in or accompanied by an officers’ certificate or be
accompanied by an opinion of counsel), as shall be specified in the order from the Corporation with respect thereto to the Trustee, as the Corporation’s agent for such purpose, to be exchanged, in whole or in part, for definitive bonds as

  
 6 

 
described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount
of definitive bonds of the same series of authorized denominations and of like tenor and terms as the portion of such Global Security to be exchanged. Promptly following any such exchange in part, such Global Security shall be returned by the
Trustee to such depositary or its custodian. If a definitive bond is issued in exchange for any portion of a Global Security after the close of business at the place where such exchange occurs on or after (i) any regular record date for a date the
interest is due (an “Interest Payment Date”) for such bond and before the opening of business at that place of payment on such Interest Payment Date, or (ii) any special record date for the payment of interest for such bond and
before the opening of business at such place of payment on the related proposed date for the payment of the interest which was not punctually paid or duly provided for on any Interest Payment Date (“Defaulted Interest”), as the case
may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such definitive bond, but shall be payable on the Interest Payment Date or proposed date for payment, as the case may
be, only to the person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of the Indenture. 

(c) Subject to Clause (b) above, any exchange or transfer of a Global Security for other bonds may be made in whole
or in part, and all bonds issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the depositary for such Global Security shall direct. 

(d) Every bond authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global
Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is registered in the name of a person other than the depositary for such Global Security or a nominee thereof.

 Section 1.04. Unless otherwise specified as contemplated by Section 2.01 for the bonds evidenced thereby, every Global Security
authenticated and delivered hereunder shall bear a legend in substantially the following form: 
 THIS SECURITY IS A GLOBAL SECURITY WITHIN
THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE
OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.

 Section 1.05. The fully registered bonds without coupons and the certificate of authentication to
be endorsed on all Series TT Bonds shall be substantially in the form set forth on Exhibit A. 
 Section 1.06. The Series TT Bonds
may contain or have imprinted thereon such provisions or specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission, or to comply with usage
with respect thereto, and may bear such other appropriate endorsements or notations as are authorized or permitted by the Indenture. 

Section 1.07. The fully registered Series TT Bonds shall be issuable in denominations of $1,000, $5,000, $10,000, $25,000 or multiples of
$25,000 and shall be dated as provided in paragraph 1 of Section 2.01 of the Base Indenture. The definitive Series TT Bonds shall be numbered in such manner as the Corporation shall at any time or from time to time determine. 

Section 1.08. In the manner and subject to certain conditions and limitations specified herein and in the Indenture, Series TT Bonds may be
exchanged without a service charge for a like aggregate principal amount of such Series TT Bonds of other authorized denomination or denominations; provided that the Corporation may require payment of a sum or sums sufficient to reimburse it for any
stamp tax or other governmental charge payable in connection therewith. 
 Section 1.09. The Corporation shall maintain in the City and
County of San Francisco, State of California and in such other place or places as the Corporation may designate at any time or from time to time, an office or agency where Series TT Bonds may be presented for payment, registration, transfer and
exchange as provided therein or in the Indenture. Such office or agency in the City and County of San Francisco, State of California shall be the corporate trust office of the Trustee unless and until the Corporation shall designate another
office or agency by notice in writing delivered to the Trustee. The Corporation hereby also designates the corporate trust office of the Trustee in the City and County of Los Angeles, State of California as an office or agency where Series TT
Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture; provided, that the Corporation shall have no obligation to continue to maintain such agency in the City and County of Los Angeles, State
of California. Notwithstanding the foregoing, if and when definitive certificated Series TT Bonds are issued under the circumstances set forth in clause (b) of Section 1.03 of this Article I, the Corporation shall also maintain in the Borough of
Manhattan, City and County of New York, State of New York, an office or agency where Series TT Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. 

Section 1.10. No transfer or exchange of any Series TT Bonds pursuant to any of the provisions of this Article I shall be made except upon and
in accordance with all of the applicable terms, provisions and conditions of said bonds and of the Indenture.

 [REVERSE SIDE OF 2.600% FIRST MORTGAGE BOND, SERIES TT, DUE 2026] 

This bond is one of a duly authorized issue of bonds of the Corporation (herein called the “bonds”), of the series
hereinafter specified, all issued and to be issued under and all equally and ratably secured by a First Mortgage Indenture dated October 1, 1940, between the Corporation and U.S. Bank National Association, as successor trustee, to which
indenture and all indentures supplemental thereto, including Supplemental Indentures dated, respectively, as of July 1, 1947, August 1, 1955, June 1, 1956, December 1, 1956, June 1, 1965, August 1, 1972, May 1,
1976, September 15, 1981, May 18, 1984, November 15, 1986, January 15, 1988, August 15, 1992, October 17, 2003, November 18, 2005, November 18, 2010, September 21, 2012, March 13, 2014, September 11, 2014, June 18, 2015,
June 18, 2015 and June 3, 2016 (herein collectively referred to, and as the same may be further amended or supplemented from time to time, as the “Indenture”), reference is hereby made for a description of the property conveyed in
trust, mortgaged and pledged, the nature and extent of the security, the rights of the registered owners of the bonds and of the trustee or trustees in respect thereof, the terms and conditions upon which the bonds are, and are to be, secured and
the circumstances under which additional bonds may be issued. The bonds may be issued for various principal sums, and may be issued in series, which may mature at different times, may bear interest at different times, may bear interest at different
rates and may otherwise vary as in the Indenture provided. This bond is one of a series designated as the “First Mortgage Bonds, Series TT, due 2026” (herein called “Series TT Bonds”) of the Corporation, issued under and
secured by the Indenture. The Supplemental Indenture dated as of June 3, 2016 relating to the Series TT Bonds is sometimes herein called the “Series TT Supplemental Indenture.” Terms used but not defined herein shall have the
respective meanings assigned thereto in the Indenture. 
 As provided in the Indenture, by any indenture or indentures supplemental thereto
executed by the Corporation and the trustee and consented to by the holders of not less than two-thirds ( 2⁄3) in principal amount of the bonds at the time
outstanding, and, in case one or more, but less than all, of the series of bonds then outstanding are affected by such supplemental indenture, consented to by the holders of at least two-thirds ( 2⁄3) in principal amount of the bonds of such series so affected, the Indenture or any indenture supplemental thereto and the rights and obligations of the Corporation and the holders of bonds, may be modified or
altered from time to time, as provided in the Indenture; provided, however, (a) that the right of any holder of any bond to receive payment of the principal of and premium, if any, and interest on such bond, on or after the respective due dates
expressed in such bond, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected by any such supplemental indenture without the consent of such holder, and (b) that no
such modification or alteration shall reduce the proportions of bondholders’ consents required as aforesaid; such proportions to be determined in each case as provided in the Indenture. 

The Series TT Bonds are entitled to the benefits of the Renewal Fund as provided in the Indenture. 

All or any portion of the Series TT Bonds may be redeemed at the Corporation’s option at any time or from time to time pursuant to this
paragraph. The price at which the Series TT Bonds will be redeemed (the “Redemption Price”) on any date fixed for such redemption (a “Redemption Date”) will be equal to (A) in the case of any Redemption Date prior
to March 15, 

  
 A-3 

 
2026 (the “Par Call Date”), the greater of the following amounts: (a) 100% of the principal amount of the Series TT Bonds being redeemed on the Redemption Date; or (b) the sum of
the present values of the remaining scheduled payments of principal and interest on the Series TT Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to the Redemption Date) that
would be due if the Series TT Bonds matured, and accrued and unpaid interest was payable, on the Par Call Date discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as
determined by the Independent Investment Banker (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption Date, or (B) in the case of any Redemption Date on or after the Par Call Date, 100% of the principal amount
of the Series TT Bonds to be redeemed on the Redemption Date, plus accrued and unpaid interest thereon to the Redemption Date. Notwithstanding the foregoing, installments of interest on Series TT Bonds that are due and payable on any Interest
Payment Dates falling on or prior to a Redemption Date will be payable on such Interest Payment Dates to the registered holders of such Series TT Bonds as of the close of business on the relevant record dates according to the terms of the Series TT
Bonds and the Indenture. The Redemption Price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months. 

Notice of any such redemption will be mailed at least 30 days, but not more than 60 days, before the Redemption Date to each registered holder
of the Series TT Bonds to be redeemed. Once notice of redemption is mailed, the Series TT Bonds called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus, if applicable, accrued and
unpaid interest to the Redemption Date. Redemption will not be conditional upon receipt by the paying agent or the trustee of monies sufficient to pay the Redemption Price. 

Unless the Corporation defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the
Series TT Bonds or portions thereof called for redemption. The Corporation will pay the Redemption Price and any accrued interest once the Series TT Bonds are surrendered for redemption. If only a portion of any Series TT Bonds is
redeemed, the trustee will deliver new Series TT Bonds for the remaining portion without charge. 
 “Adjusted Treasury
Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its
