 This security (the
“Security”) is one of a duly authorized issue of securities (herein called the “Securities”) of CSX Corporation, a Virginia corporation (hereinafter called the “Company,” which term includes any successor corporation
under the Indenture hereinafter referred to), issued and to be issued in one or more series under an indenture, unlimited as to aggregate principal amount, dated as of August 1, 1990 between the Company and JPMorgan Chase Bank, formerly known as The
Chase Manhattan Bank, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture (as hereinafter defined)), as supplemented by a First Supplemental Indenture dated as of June 15, 1991, a Second
Supplemental Indenture dated as of May 6, 1997, a Third Supplemental Indenture dated as of April 22, 1998 and a Fourth Supplemental Indenture dated as of October 30, 2001, to which indenture and all indentures supplemental thereto (the indenture, as
supplemented being herein called the “Indenture”) reference is hereby made for a statement of the respective rights 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, which series has been issued in an initial aggregate principal amount of $300,000,000 (THREE HUNDRED MILLION DOLLARS). All Securities of
this series need not be issued at the same time and such series may be reopened at any time, without the consent of any Holder, for issuances of additional Securities of this series. Any such additional Securities of this series will have the same
interest rate, maturity and other terms as those initially issued. Further Securities of this series may also be authenticated and delivered as provided by Sections 304, 305, 306 or 906 of the Indenture. This Security represents an aggregate initial
principal amount of $· (·) (as adjusted from
time to time in accordance with 







 the terms and provisions hereof and as set forth on Exhibit A hereto, the “Principal Amount”) of the Securities
of such series, with the Interest Payment Dates, date of original issuance, and date of Maturity specified herein and bearing interest on said Principal Amount at the interest rate specified herein. 
  
 The Company, for value received, hereby promises to pay CEDE & CO., or
its registered assigns, the principal sum of $· (·) on August 1, 2013 and to pay interest (computed on the basis of a 360-day year of twelve 30-day months) thereon from August 5, 2003 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, or, if
the date of this Security is an Interest Payment Date to which interest has been paid or duly provided for, then from the date hereof, semiannually in arrears on February 1 and August 1 of each year, commencing February 1, 2004, and at Maturity at
the rate of 5 1/2% per annum, until the principal hereof is paid or duly made available for payment. The Company
shall pay interest on overdue principal and premium, if any, and (to the extent lawful) interest on overdue installments of interest at the rate per annum borne by the Security. The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall
be the January 15 or July 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for shall forthwith
cease to be payable to the Holder on such Regular Record Date and may be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the
Trustee for the payment of such Defaulted Interest, notice whereof shall be given to the Holder of this Security not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange or automated quotation system on which the Securities of this series may be listed or quoted, and upon such notice as may be required by such exchange or system, all as more fully provided in such Indenture.
Notwithstanding the foregoing, interest payable on this Security at Maturity will be payable to the person to whom principal is payable. 
  
 This Security is exchangeable in whole or from time to time in part for definitive Registered Securities of this series only as provided in this
paragraph. If (x) the Depository with respect to the Securities of this series (the “Depository”) notifies the Company that it is unwilling, unable or ineligible to continue as Depository for this Security or if at any time the Depository
ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor Depository is not appointed by the Company within 90 days, (y) the Company in its sole discretion determines that this Security shall be
exchangeable for definitive Registered Securities and executes and delivers to the Trustee a Company Order providing that this Security shall be so exchangeable or (z) there shall have happened and be continuing an Event of Default or any event
which, after notice or lapse of time, or both, would become an Event of Default with respect to the Securities of the series of which this Security is a part, this Security or any portion hereof shall, in the case of clause (x) above, be exchanged
for definitive Registered Securities of this series, and in the case of clauses (y) and (z) above, be exchangeable for definitive Registered Securities of this series, provided that the definitive Security so issued in exchange for this Security
shall be in authorized denominations and be of like tenor and of an equal aggregate principal amount as the portion of the Security to be exchanged, and provided 
  

 2 








 further that, in the case of clauses (y) and (z) above, definitive Registered Securities of this series will be issued in
exchange for this Security, or any portion hereof, only if such definitive Registered Securities were requested by written notice to the Security Registrar by or on behalf of a Person who is a beneficial owner of an interest herein given through the
Holder hereof. Any definitive Registered Security of this series issued in exchange for this Security, or any portion hereof, shall be registered in the name or names of such Person or Persons as the Holder hereof shall instruct the Security
Registrar. Except as provided above, owners of beneficial interests in this Security will not be entitled to receive physical delivery of Securities in definitive form and will not be considered the Holders thereof for any purpose under the
Indenture. 
  
 Any exchange of this Security or portion hereof for
one or more definitive Registered Securities of this series will be made at the New York office of the Security Registrar. Upon exchange of any portion of this Security for one or more definitive Registered Securities of this series, the Trustee
shall endorse Exhibit A of this Security to reflect the reduction of its Principal Amount by an amount equal to the aggregate principal amount of the definitive Registered Securities of this series so issued in exchange, whereupon the Principal
Amount hereof shall be reduced for all purposes by the amount so exchanged and noted. Except as otherwise provided herein or in the Indenture, until exchanged in full for one or more definitive Registered Securities of this series, this Security
shall in all respects be subject to and entitled to the same benefits and conditions under the Indenture as a duly authenticated and delivered definitive Registered Security of this series. 
  
 The principal and any interest in respect of any portion of this Security
payable in respect of an Interest Payment Date or at the Stated Maturity thereof, in each case occurring prior to the exchange of such portion for a definitive Registered Security or Securities of this series, will be paid, as provided herein, to
the Holder hereof which will undertake in such circumstances to credit any such principal and interest received by it in respect of this Security to the respective accounts of the Persons who are the beneficial owners of such interests on such
Interest Payment Date or at Stated Maturity. If a definitive Registered Security or Registered Securities of this series are issued in exchange for any portion of this Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, then interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Holder hereof, and the Holder hereof will undertake in such circumstances to credit such interest to the account or accounts of the Persons
who were the beneficial owners of such portion of this Security on such Regular Record Date or Special Record Date, as the case may be. 
  
 Payment of the principal of and any such interest on this Security will be made at the offices of JPMorgan Chase Bank, as Paying Agent, in the Borough of
Manhattan, The City of New York, or at such other office or agency of the Company as may be designated by it for such 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 shall be legal tender for the payment of public and private debts by check mailed to the registered Holders thereof; provided, however, 
  


 3 








 that at the option of the Holder, payment of interest may be made by wire transfer of immediately available funds to an
account of the Person entitled hereto as such account shall be provided to the Security Registrar and shall appear in the Security Register. 
  
 The Securities shall be redeemable, in whole or in part, at the Company’s option at any time. The Redemption Price for the Securities to be redeemed
shall equal the greater of the following amounts, plus, in each case, accrued interest thereon to the Redemption Date: 
  

	 	•	 	100% of the principal amount of such Securities; or 

  

	 	•	 	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 any payments of interest accrued from the most recent Interest Payment Date to which interest has been paid to the Redemption Date) discounted to the Redemption Date on a semiannual basis at the Adjusted Treasury Rate
(as defined below) plus 20 basis points. 

  
 The Redemption Price
shall be calculated by the Independent Investment Banker assuming a 360-day year consisting of twelve 30-day months. 
  
 “Adjusted Treasury Rate” means, with respect to any Redemption Date: 
  

	 	•	 	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 remaining term of the Securities, yields for the two published
maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or


  

	 	•	 	if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per 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 principal amount) equal to the Comparable Treasury Price for such Redemption Date.


  
 The Adjusted Treasury Rate shall be calculated
on the third Business Day preceding the Redemption Date. The Company shall notify the Trustee, in an Officers’ Certificate, of the Redemption Price no later than the second Business Day preceding the Redemption Date. The Officers’
Certificate shall set forth the Redemption Price both as an aggregate amount for all the 
  

 4 








 Securities to be redeemed and as an amount per $1,000 in principal amount of the Securities to be redeemed. 

 
 “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 Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Securities. 
  
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of five Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest such 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.

  
 “Independent Investment Banker” means J.P. Morgan
Securities Inc. and its successors, or if that firm is unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company. 
  
 “Reference Treasury Dealer” means: 
  

	 	•	 	J.P. Morgan Securities Inc. and its successors; provided that, if J.P. Morgan Securities Inc. ceases to be a primary U.S. Government securities dealer in New York City
(“Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and 

  

	 	•	 	up to four other Primary Treasury Dealers selected by 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 in writing to the Independent Investment Banker by such Reference Treasury
Dealer at 5:00 p.m. (New York City time) on the third business day preceding such Redemption Date. 
  
 Notice of redemption shall be given as provided in Section 1104 of the Indenture; provided, that such notice shall not be required to include the
Redemption Price but shall instead include the manner of calculation of the Redemption Price. If the Company elects to partially redeem the Securities, the Trustee will select in a fair and appropriate manner the Securities to be redeemed.

  
 Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date interest will cease to accrue on the Securities or portions thereof called for redemption. 
  
 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 (including
this Security and the interests 
  

 5 








 represented hereby) may be declared due and payable in the manner and with the effect provided in the Indenture. Upon
payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal and overdue interest (in each case 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 and any interest on the Securities of this series (including this Security and the interests represented hereby) shall terminate. 
  
 The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Security and (b) certain restrictive covenants and the related defaults and Events of Default, upon compliance with certain conditions set forth therein, which provisions shall apply to this Security.

  
 The provisions of Article Fourteen of the Indenture apply to
Securities of this series. 
  
 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 aggregate principal amount of the Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages
in aggregate principal amount of the Securities of each series at the time Outstanding on behalf of the Holders of all Securities of such series to waive compliance by the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and the Persons who are beneficial owners of
interests represented hereby, and of any Security issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security. 
  
 As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any
right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Securities of this
series, the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, and the
Trustee shall not have received from the Holders of a majority in aggregate principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of (and premium, if any) or interest on this Security on or after the respective due dates expressed
herein. 
  
 No reference herein to the Indenture and no provision
of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional to pay the principal of (and premium, if any) and interest on this Security at the time, place and rate, and in the coin or
currency, herein prescribed. 
  

 6 








 As provided in the Indenture and subject to certain limitations therein and herein set forth, the
transfer of Registered Securities of the series of which this Security is a part may be registered on the Security Register of the Company, upon surrender of such Securities for registration of transfer at the office of the Security Registrar, 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 thereof or his attorney duly authorized in writing, and thereupon one or two 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. 
  
 No service charge shall be made for any such registration of transfer or exchange of Securities as provided above, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
  
 Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
  
 The Securities of this series of which this Security is a part are issuable
only in registered form without coupons, in denominations of $1,000.00 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the 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. 
  
 The Securities of this series shall be dated the date of their authentication. 
  
 All terms used in this Security which are defined in the Indenture shall have
the meanings assigned to them in the Indenture. 
  
 Unless the
certificate of authentication hereon has been executed by or on behalf of JPMorgan Chase Bank, the Trustee under the Indenture, or its successor thereunder, by the manual signature of one of its authorized officers, this Security shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
