TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

     This prospectus is part of a shelf registration statement that CSX Corporation filed with the Securities and Exchange Commission. Under the shelf registration statement, CSX may sell, separately or in units, any combination of the securities described in this prospectus in one or more offerings up to a total dollar amount of $1,200,000,000. For further information about our business and the securities, you should refer to the registration statement and its exhibits. The exhibits to the registration statement and the documents we incorporate by reference contain the full text of certain contracts and other important documents summarized in this prospectus. Since these summaries may not contain all the information that you may find important in deciding whether to purchase the securities CSX may offer, you should review the full text of those documents. The registration statement can be obtained from the SEC as indicated under the heading “Where You Can Find More Information.”

     This prospectus provides you with a general description of the securities CSX may offer. Each time CSX sells securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. Any material United States federal income tax considerations will also be discussed in the applicable prospectus supplement. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.” In this prospectus, unless otherwise indicated, the words “CSX,” “we,” “our” and “us” refer to CSX Corporation, a Virginia corporation, and our subsidiaries.

CSX CORPORATION

     CSX, incorporated in Virginia in 1978 and headquartered in Jacksonville, Florida, operates one of the largest rail networks in the United States and also arranges for and provides integrated rail and truck (“intermodal”) transportation services across the United States and key markets in Canada and Mexico. Our marine operations include an international terminal services company, which operates and develops container terminals, distribution facilities and related terminal activities.

Operating Segments

     Set forth below are CSX’s operating revenue and operating income by segment for the fiscal year ended December 26, 2003:

Surface Transportation

     CSX Transportation Inc. (“CSXT”) operates the largest rail network in the eastern United States, providing rail freight transportation over a network of more than 23,000 route miles in 23 states, the District of Columbia and two Canadian provinces. Headquartered in Jacksonville, Florida, CSXT accounted for 79% of CSX’s operating revenue and 86% of operating income in 2003.

     CSX Intermodal Inc. (“CSXI”) is the nation’s only transcontinental intermodal transportation service provider, operating a network of dedicated intermodal facilities across North America. The CSXI network runs approximately 450 dedicated trains between its 45 terminals weekly. CSXI accounted for 16% of CSX’s operating revenue and 18% of operating income in 2003. Its headquarters are located in Jacksonville, Florida.

International Terminals

     CSX World Terminals LLC (“CSXWT”) operates container-freight terminal facilities in Asia, Europe, Australia, Latin America and the United States. CSXWT accounted for 3% of CSX’s operating revenues and 11% of operating income in 2003. CSXWT is headquartered in Charlotte, North Carolina.

Non-Transportation

     Our non-transportation holdings include: The Greenbrier, a AAA Five-Diamond resort in White Sulphur Springs, West Virginia; and CSX Real Property Inc., which is responsible for sales, leasing and development of CSX-owned properties and is headquartered in Jacksonville, Florida.

CSX CAPITAL TRUST I

     CSX Capital Trust I, which is referred to in this prospectus as the “Trust,” is a statutory trust formed under Delaware law by us, as sponsor for the Trust, and Chase Manhattan Bank USA, National Association, who will serve as trustee in the State of Delaware for the purpose of complying with the provisions of the Delaware Statutory Trust Act. The trust agreement for the Trust will be amended and restated substantially in the form filed as an exhibit to the registration statement, effective when securities of the Trust are initially issued. The amended trust agreement will be qualified as an indenture under the Trust Indenture Act of 1939. The Trust exists for the exclusive purposes of:

     Subordinated debt securities of CSX will be the sole assets of the Trust, and our payments under those subordinated debt securities and the agreement as to expenses and liabilities will be the sole revenue of the Trust. No separate financial statements of the Trust are included in this prospectus. CSX considers that those financial statements would not be material to holders of the trust preferred securities because the Trust has no independent

4

operations and the purpose of the Trust is as described above. The Trust is not required to file annual, quarterly or special reports with the SEC.

     The principal place of business of the Trust will be c/o CSX Corporation, 500 Water Street, 15th Floor, Jacksonville, Florida 32202, telephone number (904) 359-3200.

FORWARD-LOOKING STATEMENTS

     This prospectus, including documents incorporated by reference, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Exchange Act with respect to, among other items:

     Forward-looking statements are subject to a number of risks and uncertainties, and actual performance or results could differ materially from those anticipated by these forward-looking statements. Forward-looking statements are typically identified by words or phrases such as “believe,” “expect,” “anticipate,” “project,” and similar expressions.

     Factors that may cause actual results to differ materially from those contemplated by these forward-looking statements include, among others:

     Other important assumptions and factors that could cause actual results to differ materially from those in the forward-looking statements are specified elsewhere in this prospectus and in our Annual Report on Form 10-K and our other SEC reports, accessible on the SEC’s website at www.sec.gov and our website at www.csx.com.

5

     Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update or revise any forward-looking statement. If we do update any forward-looking statement, no inference should be drawn that we will make additional updates with respect to that statement or any other forward-looking statements.

RATIO OF EARNINGS TO FIXED CHARGES

     CSX’s consolidated ratio of earnings to fixed charges for each of the fiscal periods indicated is as follows:

USE OF PROCEEDS

     CSX will use the net proceeds from the sale of the securities for general corporate purposes, which may include reduction or refinancing of outstanding indebtedness, capital expenditures, working capital requirements, implementation of work force reductions, improvements in productivity and other cost reductions at our major surface transportation and international terminals units, and redemptions and repurchases of certain outstanding securities. CSX has not specifically allocated the proceeds to those purposes as of the date of this prospectus. The precise amount and timing of the application of proceeds from the sale of securities will depend upon the funding requirements of CSX and the availability and cost of other funds at the time of the sale. Allocation of the proceeds of a particular series of securities, or the principal reasons for the offering if no allocation has been made, will be described in the applicable prospectus supplement.

6

DESCRIPTION OF DEBT SECURITIES

     CSX may issue debt securities either separately, or together with, or upon the conversion of or in exchange for, other securities. The debt securities will be either senior unsecured obligations or subordinated unsecured obligations of CSX. Senior debt securities will be issued under a senior indenture dated as of August 1, 1990 between CSX and JPMorgan Chase Bank, formerly The Chase Manhattan Bank, as trustee, as currently supplemented and amended and as further supplemented and amended from time to time. Subordinated debt securities will be issued under a subordinated indenture to be entered into between CSX and JPMorgan Chase Bank, as trustee, as further supplemented and amended from time to time. Copies of the senior indenture and a form of the subordinated indenture have been incorporated by reference in, or filed as exhibits to, the registration statement of which this prospectus is a part. The senior indenture and the subordinated indenture are sometimes referred to collectively as the “indentures.” The trustee under the senior indenture and the trustee under the subordinated indenture are sometimes referred to collectively as the “trustees.”

     The summary of certain provisions of the indentures and the debt securities set forth below and the summary of certain terms of a particular series of debt securities set forth in the applicable prospectus supplement do not purport to be complete and are subject to and are qualified in their entirety by reference to all of the provisions of the indentures, which provisions of the indentures (including defined terms) are incorporated in this description of debt securities by reference.

     The debt securities may be issued from time to time in one or more series of senior debt securities and one or more series of subordinated debt securities. Neither indenture limits the aggregate principal amount of debt securities that may be issued under it. Unless otherwise provided in the terms of a series, a series may be reopened, without notice to or consent of any holder of outstanding debt securities, for issuances of additional debt securities of that series. The terms of each series of debt securities will be established by or pursuant to a resolution of our Board of Directors and set forth or determined in the manner provided in an officer’s certificate or by a supplemental indenture. The following description of debt securities summarizes certain general terms and provisions of the series of debt securities to which any prospectus supplement may relate. The particular terms of each series of debt securities offered by a prospectus supplement or prospectus supplements will be described in the prospectus supplement or prospectus supplements relating to that series.

     Unless otherwise indicated, currency amounts in this prospectus and any prospectus supplement are stated in United States dollars.

General

     The prospectus supplement for a particular series of debt securities will describe the specific terms of that series, including (where applicable):

7

8

     The prospectus supplement will also describe any special provisions for the payment of additional amounts relating to specified taxes, assessments or other governmental charges in respect of the debt securities of that series and whether CSX has the option to redeem the affected debt securities rather than pay those additional amounts.

     As used in this prospectus and any prospectus supplement relating to the offering of any debt securities, references to the principal of and premium, if any, and interest, if any, on the debt securities will be deemed to include mention of the payment of additional amounts, if any, required by the terms of the debt securities.

     If the purchase price of any debt securities is payable in a currency other than U.S. dollars or if principal of, or premium, if any, or interest, if any, on any of the debt securities is payable in any currency other than U.S. dollars, the specific terms and other information with respect to those debt securities and that currency will be specified in the related prospectus supplement.

     Debt securities of a series may also be issued under the indenture upon the exercise of debt warrants issued by CSX. See “Description of Debt Warrants.”

     The indentures do not contain any provisions that may afford the holders of debt securities of any series protection in the event of a highly leveraged transaction or other transaction that may occur in connection with a takeover attempt resulting in a decline in the credit rating of the debt securities. Those provisions, if applicable to the debt securities of any series, will be described in the related prospectus supplement.

Form, Exchange, Registration and Transfer

     Unless otherwise indicated in the applicable prospectus supplement, each series of debt securities will be issued in registered form only, without coupons. The indentures, however, provide that CSX may also issue debt securities in bearer form only, or in both registered and bearer form. Bearer debt securities will not be offered, sold, resold or delivered in connection with their original issuance in the United States or to any United States person other than offices located outside the United States of certain United States financial institutions. Purchasers of bearer debt securities will be subject to certification procedures and may be affected by certain limitations under United States tax laws. Those procedures and limitations will be described in the prospectus supplement relating to the offering of the bearer debt securities. Unless otherwise indicated in an applicable prospectus supplement or prospectus supplements, bearer debt securities will have interest coupons attached. The indentures also will provide that debt securities of a series may be issuable in temporary or permanent global form. See “Global Debt Securities.”

     At the option of the holder, subject to the terms of the relevant indenture, registered debt securities of any series will be exchangeable for other registered debt securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor. In addition, if debt securities of any series are issuable as both registered debt securities and bearer debt securities, at the option of the holder, subject to the terms of the relevant indenture, bearer debt securities (with all unmatured coupons, except as provided below, and with all matured coupons in default) of that series will be exchangeable for registered debt securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor. Bearer debt securities surrendered in exchange for registered debt securities between a regular record date or a special record date and the relevant date for payment of interest will be surrendered without the coupon relating to that date for payment of interest and interest will not be payable in respect of the registered debt security issued in exchange for that bearer debt security, but will be payable only to the holder of the coupon when due in accordance with the terms of the indenture. Registered debt securities, including registered debt securities received in exchange for bearer debt securities, may not be exchanged for bearer debt securities. Each bearer debt security and coupon will bear a legend to the following effect:

“Any United States person who holds this obligation will be subject to limitations under the United States income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code.”

     Debt securities may be presented for exchange as provided above, and registered debt securities may be presented for registration of transfer (with the form of transfer duly executed), at the office of the security registrar

9

or at the office of any transfer agent designated by CSX for that purpose with respect to any series of debt securities and referred to in an applicable prospectus supplement, without a service charge and upon payment of any taxes and other governmental charges as described in the relevant indenture. The transfer or exchange will be effected upon the records of the security registrar or the transfer agent, as the case may be, being satisfied with the documents of title and identity of the person making the request. CSX has appointed the trustee as security registrar. If a prospectus supplement refers to any transfer agent (in addition to the security registrar) initially designated by CSX with respect to any series of debt securities, CSX may at any time rescind the designation of that transfer agent or approve a change in the location through which that transfer agent acts, except that, if debt securities of a series are issuable solely as registered debt securities, CSX will be required to maintain a transfer agent in each place of payment for that series and, if debt securities of a series are issuable as bearer debt securities, CSX will be required to maintain (in addition to the security registrar) a transfer agent in a place of payment for that series located outside the United States and its possessions. CSX may at any time designate additional transfer agents with respect to any series of debt securities.

In the event of any partial redemption, CSX will not be required to:

Payment and Paying Agents

     Unless otherwise indicated in an applicable prospectus supplement, principal of and any premium and interest on bearer debt securities will be payable, subject to any applicable laws and regulations, at the offices of paying agents outside the United States and its possessions that CSX may designate from time to time or, at the option of the holder, by check or by transfer to an account maintained by the payee with a financial institution located outside the United States and its possessions. Unless otherwise indicated in an applicable prospectus supplement, payment of interest on a bearer debt security on any interest payment date will be made only against surrender to the paying agent of the coupon relating to that interest payment date. No payment with respect to any bearer debt security will be made at any office or agency of CSX in the United States or its possessions or by check mailed to any address in the United States or its possessions or by transfer to any account maintained with a financial institution located in the United States or its possessions. However, payments of principal of and any premium and interest on bearer debt securities denominated and payable in U.S. dollars will be made at the office of the paying agent in the Borough of Manhattan, The City of New York, if (but only if) payment of the full amount in U.S. dollars at all offices or agencies outside the United States and its possessions is illegal or effectively precluded by exchange controls or other similar restrictions.

     Unless otherwise indicated in an applicable prospectus supplement, principal of and any premium and interest on registered debt securities will be payable, subject to any applicable laws and regulations, at the office of the paying agent or paying agents that CSX may designate from time to time, except that at our option payment of any interest may be made by check mailed to the address of the person entitled to that payment as that address appears in the security register. Unless otherwise indicated in an applicable prospectus supplement, payment of interest on a registered debt security on any interest payment date will be made to the person in whose name that registered debt security (or predecessor debt security) is registered at the close of business on the regular record date for that interest.

10

     Unless otherwise indicated in an applicable prospectus supplement, the corporate trust office of the trustee in The City of New York will be designated as a paying agent for CSX for payments with respect to debt securities of each series which are issuable solely as registered debt securities and as a paying agent for payments with respect to debt securities of each series (subject to the limitations described above in the case of bearer debt securities) which are issuable solely as bearer debt securities or as both registered debt securities and bearer debt securities. Any paying agents outside the United States and its possessions and any other paying agents in the United States or its possessions initially designated by CSX for the debt securities of each series will be named in the applicable prospectus supplement. CSX may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that if debt securities of a series are issuable solely as registered debt securities, CSX will be required to maintain a paying agent in each place of payment for that series and, if debt securities of a series are issuable as bearer debt securities, CSX will be required to maintain:

provided, however, that if the debt securities of that series are listed on The International Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange located outside the United States and its possessions and that stock exchange requires CSX to do so, CSX will maintain a paying agent in London, Luxembourg or any other required city located outside the United States and its possessions, as the case may be, for the debt securities of that series.

     All moneys paid by CSX to a paying agent for the payment of the principal of and any premium or interest on any debt security of any series which remain unclaimed at the end of two years after that principal, premium or interest has become due and payable will be repaid to CSX and the holder of that debt security or any related coupon will after that time look only to CSX for payment of that principal, premium or interest.

Ranking of Debt Securities; Holding Company Structure

     The senior debt securities will be unsecured unsubordinated obligations of CSX and will rank on a parity in right of payment with all other unsecured and unsubordinated indebtedness of CSX. The subordinated debt securities will be unsecured obligations of CSX and will be subordinated in right of payment to all existing and future senior indebtedness (as defined below) of CSX. See “Additional Terms of Subordinated Debt Securities – Subordination.”

     The debt securities are obligations exclusively of CSX. CSX is a holding company, substantially all of whose consolidated assets are held by our subsidiaries. Accordingly, the cash flow of CSX and the consequent ability to service our debt, including the debt securities, are largely dependent upon the earnings of those subsidiaries.

     Because CSX is a holding company, the debt securities will be effectively subordinated to all existing and future indebtedness, trade payables, guarantees, lease obligations and letter of credit obligations of CSX’s subsidiaries. Therefore, CSX’s rights and the rights of our creditors, including the holders of the debt securities, to participate in the assets of any subsidiary upon the latter’s liquidation or reorganization will be subject to the prior claims of that subsidiary’s creditors, except to the extent that CSX may itself be a creditor with recognized claims against the subsidiary, in which case the claims of CSX would still be effectively subordinate to any security interest in, or mortgages or other liens on, the assets of that subsidiary and would be subordinate to any indebtedness of that subsidiary senior to that held by CSX. Although certain debt instruments to which CSX and our subsidiaries are parties impose limitations on the incurrence of additional indebtedness, both CSX and our subsidiaries retain the ability to incur substantial additional indebtedness and lease and letter of credit obligations.

11

Global Debt Securities

     The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the prospectus supplement relating to that series. Global debt securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for individual certificates evidencing debt securities in definitive form, a global debt security may not be transferred except as a whole by the depositary for that global debt security to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any nominee to a successor of the depositary or a nominee of the successor.

     The specific terms of the depositary arrangement with respect to a series of global debt securities and certain limitations and restrictions relating to a series of global bearer debt securities will be described in the prospectus supplement relating to that series.

Redemption and Repurchase

     The debt securities of any series may be redeemable at our option, may be subject to mandatory redemption pursuant to a sinking fund or otherwise, or may be subject to repurchase by us at the option of the holders, in each case upon the terms, at the times and at the prices set forth in the applicable prospectus supplement.

Conversion and Exchange

     The terms, if any, on which debt securities of any series are convertible into or exchangeable for our common stock, preferred stock, depositary shares or other debt securities will be set forth in the applicable prospectus supplement. Those terms may include provisions for conversion or exchange, either mandatory, at the option of the holders or at our option.

Certain Covenants and Agreements of CSX

     The indentures do not limit the amount of indebtedness or lease obligations that may be incurred by CSX and our subsidiaries. The indentures do not contain provisions that would give holders of the debt securities the right to require CSX to repurchase their debt securities in the event of a decline in the credit rating of our debt securities resulting from a takeover, recapitalization or similar restructuring.

     Covenant in the Senior Indenture–Limitation on Liens on Stock of Our Principal Subsidiaries.

     The following covenant will be applicable to senior debt securities but not to subordinated debt securities. The senior indenture provides that CSX may not, nor may it permit any subsidiary to, create, assume, incur or suffer to exist any mortgage, pledge, lien, encumbrance, charge or security interest of any kind upon any stock or indebtedness, whether owned on the date of the senior indenture or acquired later, of any principal subsidiary, to secure any obligation (other than the senior debt securities) of CSX, any subsidiary or any other person, unless all of the outstanding senior debt securities (and other outstanding debt securities issued from time to time pursuant to the senior indenture) will be directly secured equally and ratably with that obligation. This provision does not restrict any other property of CSX or our subsidiaries. The senior indenture defines “obligation” as indebtedness for money borrowed or indebtedness evidenced by a bond, note, debenture or other evidence of indebtedness; “principal subsidiary” as CSXT; and “subsidiary” as a corporation a majority of the outstanding voting stock of which is owned, directly or indirectly, by CSX or one or more subsidiaries, or by CSX and one or more subsidiaries. The indentures do not prohibit the sale by CSX or any subsidiary of any stock or indebtedness of any subsidiary, including any principal subsidiary.

     Provision in Both Indentures–Consolidation, Merger and Sale of Assets.

     The following provision will be applicable to both senior debt securities and subordinated debt securities. Each indenture provides that CSX may, without the consent of the holders of any of the outstanding debt securities

12

of a series, consolidate with, merge into or transfer our assets substantially as an entirety to any corporation organized under the laws of any domestic or foreign jurisdiction, provided that:

Events of Default

     An “event of default” with respect to the debt securities of any series is defined in the relevant indenture as being:

     No event of default with respect to any particular series of debt securities necessarily constitutes an event of default with respect to any other series of debt securities. Each indenture provides that the trustee may withhold notice to the holders of the debt securities of any series of the occurrence of a default with respect to the debt securities of that series (except a default in payment of principal, premium, if any, interest, if any, or sinking fund payments, if any) if the trustee considers it in the interest of the holders to do so.

     Subject to the provisions of the Trust Indenture Act requiring each trustee, during an event of default under the relevant indenture, to act with the requisite standard of care, and to the provisions of the relevant indenture relating to the duties of the trustee in case an event of default occurs and is continuing, a trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of debt securities of any series or any related coupons unless those holders offer to the trustee reasonable indemnity. Subject to the provisions for the indemnification of the relevant trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the relevant trustee, or exercising any trust or power conferred on the trustee, with respect to debt securities of that series.

     If an event of default with respect to debt securities of any series at the time outstanding occurs and is continuing, either the relevant trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal of all those outstanding debt securities to be due and payable immediately. At any time after a declaration of acceleration with respect to debt securities of any series has been made but before a judgment or decree for payment of money due has been obtained by the relevant trustee, the holders of a majority in aggregate principal amount of outstanding debt securities of that series may rescind any

13

declaration of acceleration and its consequences, if all payments due (other than those due as a result of acceleration) have been made and all events of default have been cured or waived.

     No holder of any debt securities of any series or any related coupons will have any right to institute any proceeding with respect to the relevant indenture or for any remedy under the indenture, unless that holder has previously given to the relevant trustee written notice of a continuing event of default with respect to debt securities of that series, the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and offered reasonable indemnity, to the relevant trustee to institute the proceeding as trustee, and the trustee has not received from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series a direction inconsistent with that request and has failed to institute the proceeding within 60 days. However, these limitations do not apply to a suit instituted by a holder of an outstanding debt security of that series for enforcement of payment of the principal of, or any premium or interest on, that debt security on or after the respective due dates expressed in that debt security.

     CSX is required to furnish to the relevant trustee annually a statement as to performance or fulfillment of covenants, agreements or conditions in the relevant indenture and as to the absence of default.

Meetings, Modification and Waiver

     Each indenture contains provisions permitting CSX and the relevant trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of each series issued under that indenture and affected by a modification or amendment (voting as one class), to modify or amend any of the provisions of that indenture or of those debt securities or the rights of the holders of those debt securities under that indenture, provided that no modification or amendment will, without the consent of each holder of each outstanding debt security affected by that modification or amendment:

     Each indenture also contains provisions permitting CSX and the relevant trustee, without the consent of the holders of the debt securities issued under the indenture, to modify or amend the indenture in order, among other things:

14

     The holders of at least a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of the holders of all the debt securities of that series, waive, insofar as that series is concerned, compliance by CSX with certain restrictive provisions of the indenture, including the covenant described above under “–Certain Covenants and Agreements of CSX–Covenant in the Senior Indenture–Limitation on Liens on Stock of Our Principal Subsidiaries.” The holders of not less than a majority in aggregate principal amount of the outstanding debt securities of a series may, on behalf of all holders of debt securities of that series and any related coupons, waive any past default under the indenture with respect to debt securities of that series, except a default (a) in the payment of principal of or any premium or interest on any debt security of that series or (b) in respect of a covenant or provision of the indenture which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected.

     Each indenture provides that in determining whether the holders of the requisite principal amount of the outstanding debt securities have given any request, demand, authorization, direction, notice, consent or waiver under that indenture or are present at a meeting of holders of debt securities for quorum purposes:

     Each indenture contains provisions for convening meetings of the holders of debt securities of any or all series. A meeting may be called at any time by the relevant trustee, and also, upon request, by CSX or the holders of at least 10% in aggregate principal amount of the outstanding debt securities of that series, in each case upon notice given in accordance with “Notices” below and the provisions of the relevant indenture. Except for any consent which must be given by the holder of each outstanding debt security that would be affected as described above, any resolution presented at a meeting, or adjourned meeting duly reconvened, at which a quorum (as described below) is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series; provided, however, that, except for any consent which must be given by the holder of each outstanding debt security that would be affected, as described above, any resolution with respect to any consent, waiver, request, demand, notice, authorization, direction or other action which may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of a series may be adopted at a meeting, or an adjourned meeting duly reconvened, at which a quorum is present only by the

15

affirmative vote of the holders of not less than the specified percentage in principal amount of the outstanding debt securities of that series.

     Any resolution passed or action taken at any meeting of holders of debt securities of any series duly held in accordance with the relevant indenture will be binding on all holders of debt securities of that series and the related coupons. The quorum required for any meeting called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the outstanding debt securities of a series; provided, however, that if any action is to be taken at that meeting with respect to a consent, waiver, request, demand, notice, authorization, direction or other action which may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of a series, the persons holding or representing that specified percentage in principal amount of the outstanding debt securities of the series will constitute a quorum.

Notices

     Except as otherwise provided in the indenture, notices to holders of bearer debt securities will be given by publication at least twice in a daily newspaper of general circulation in The City of New York and in any other city or cities as may be specified in those debt securities. Notices to holders of registered debt securities will be given by mail to the addresses of those holders as they appear in the security register.

Title

     Title to any bearer debt securities (including bearer debt securities in temporary global form and in permanent global form) and any related coupons will pass by delivery. CSX, the trustee and any agent of CSX or the trustee may treat the bearer of any bearer debt security and the bearer of any coupon and the registered owner of any registered debt security as the absolute owner (whether or not that debt security or coupon is overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

Replacement of Debt Securities

     Any mutilated debt security or a debt security with a mutilated coupon will be replaced by CSX at the expense of the holder upon surrender of that debt security to the relevant trustee. Debt securities or coupons that become destroyed, lost or stolen will be replaced by CSX at the expense of the holder upon delivery to the relevant trustee of evidence of the destruction, loss or theft satisfactory to CSX and the relevant trustee; in the case of any coupon which becomes destroyed, lost or stolen, that coupon will be replaced by issuance of a new debt security in exchange for the debt security to which the coupon appertains. In the case of a destroyed, lost or stolen debt security or coupon, an indemnity satisfactory to the trustee and CSX may be required at the expense of the holder of that debt security or coupon before a replacement debt security will be issued.

Discharge, Defeasance and Covenant Defeasance

     Upon the direction of CSX, either indenture will generally cease to be of further effect with respect to any series of debt securities issued under that indenture specified by CSX (subject to the survival of certain provisions of that indenture) when:

16

     In addition, unless otherwise provided in an applicable prospectus supplement, CSX may elect with respect to any series of debt securities either

     If we exercise our defeasance option with respect to any series of debt securities, payment of those debt securities may not be accelerated because of an event of default. If we exercise our covenant defeasance option with respect to any series of debt securities, payment of those debt securities may not be accelerated because of an event of default related to the covenants noted under clause (2) of the immediately preceding paragraph. We may exercise our defeasance option with respect to those debt securities even though we may have previously exercised our covenant defeasance option.

     If CSX effects covenant defeasance with respect to any debt securities and those debt securities are declared due and payable because of the occurrence of any event of default other than an event of default with respect to the covenant described above under “–Certain Covenants and Agreements of CSX–Covenant in the Senior Indenture–Limitation on Liens on Stock of Our Principal Subsidiaries” (which covenant appears only in the senior indenture and which would no longer be applicable to those debt securities after the covenant defeasance) or with respect to any other covenant as to which there has been covenant defeasance, the amount of monies and/or government obligations deposited with the applicable trustee to effect the covenant defeasance may not be sufficient to pay amounts due on those debt securities at the time of any acceleration resulting from the event of default. However, we would remain liable to make payment of those amounts due at the time of acceleration.

     We may exercise our defeasance option or our covenant defeasance option with respect to any series of debt securities, only if:

17

     The opinion of counsel, with respect to defeasance, referred to in clause (5) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the relevant indenture.

     The trustee must hold in trust cash or U.S. government obligations deposited with it as described above and must apply the deposited cash and the proceeds from deposited U.S. government obligations to the payment of principal, premium, if any, and interest with respect to the debt securities.

     The applicable prospectus supplement may further describe the provisions, if any, permitting or restricting defeasance or covenant defeasance with respect to the debt securities of a particular series.

Governing Law

     The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustees

     The Trust Indenture Act of 1939 contains limitations on the rights of a trustee, should it become a creditor of CSX, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of those claims, as security or otherwise. Each trustee is permitted to engage in other transactions with CSX and our subsidiaries from time to time, provided that if the trustee acquires any conflicting interest it must eliminate the conflict upon the occurrence of an event of default under the relevant indenture, or else resign.

     CSX and certain of our subsidiaries may from time to time maintain lines of credit, and have other customary banking and commercial relationships, with JPMorgan Chase Bank, the senior trustee and the subordinated trustee, and its affiliates. JPMorgan Chase Bank acts as trustee under the senior indenture and another indenture pursuant to which we issued our Series A Medium-Term Notes, Series B Medium-Term Notes, Series C Medium Term Notes 7.25% Debentures due 2004, 2.75% Notes due 2006, 9.00% Debentures due 2006, 7.45% Debentures due 2007, 6.25% Notes due 2008, 4.875% Notes due 2009, 6.75% Notes due 2011, 6.30% Notes due 2012, 5 1/2% Notes due 2013, 5.30% Notes due 2014, 7.90% Debentures due 2017, Zero Coupon Convertible Debentures due October 30, 2021, 8.625% Debentures due 2022, 8.10% Debentures due 2022, 7.95% Debentures due 2027, 7.25% Debentures due 2027 and 8.30% Debentures due 2032.

ADDITIONAL TERMS OF SUBORDINATED DEBT SECURITIES

Additional Covenants Applicable to Subordinated Debt Securities

     Under the subordinated indenture, or under one or more supplemental indentures to the subordinated indenture, we will:

Option to Extend Interest Payment Period

     If so indicated in the prospectus supplement, we can defer interest payments by extending the interest payment period for the number of consecutive extension periods specified in the applicable prospectus supplement. Other details regarding the extension period will also be specified in the applicable prospectus supplement. No extension period may extend beyond the maturity of the applicable subordinated debt securities. At the end of the extension period(s), we will pay all interest then accrued and unpaid, together with interest compounded quarterly at the rate for the applicable subordinated debt securities, to the extent permitted by applicable law.

     During any extension period, we will not make distributions related to our capital stock, including dividends, redemptions, repurchases, liquidation payments, or guarantee payments. Also, we will not make any payments, redeem or repurchase any debt securities of equal or junior rank to the subordinated debt securities or make any guarantee payments on any such debt securities. We may, however, make the following types of distributions:

Subordination

     The payment of the principal of, premium, if any, and interest, if any, on the subordinated debt securities will be subordinated, to the extent and in the manner set forth in the subordinated indenture, in right of payment to the prior payment in full of all senior indebtedness which may at any time and from time to time be outstanding. Unless otherwise provided in the applicable prospectus supplement with respect to an issue of subordinated debt securities, in the event of any distribution of our assets upon any dissolution, winding up, liquidation, reorganization or other similar proceedings of CSX:

19

     Subject to the payment in full of all senior indebtedness upon any distribution of our assets, the holders of the subordinated debt securities will be subrogated to the rights of the holders of the senior indebtedness to the extent of payments made to the holders of senior indebtedness out of the distributive share of the subordinated debt securities.

     By reason of subordination of the subordinated debt securities, if there is any distribution of our assets upon dissolution, winding up, liquidation, reorganization or other similar proceedings of CSX,

Furthermore, subordination may result in a reduction or elimination of payments to the holders of subordinated debt securities. The subordinated indenture provides that the subordination provisions in the subordinated indenture will not apply to any money and securities held in trust pursuant to the discharge, defeasance and covenant defeasance provisions of the subordinated indenture (see “–Discharge, Defeasance and Covenant Defeasance” above).

     The subordinated indenture also provides that no payment on account of the principal of, or premium, if any, sinking funds, if any, or interest, if any, on the subordinated debt securities will be made unless full payment of amounts then due for the principal of, premium, if any, sinking funds, if any, and interest, if any, on senior indebtedness has been made or duly provided for.

     Senior indebtedness means, with respect to any series of subordinated debt securities, the principal, premium, interest and any other payment in respect of any of the following:

20

unless, in the instrument creating or evidencing any liability referred to in clause (1) or (2) above or any deferral, renewal, extension or refunding referred to in clause (3) above or pursuant to which the same is outstanding, it is expressly provided that the liability, deferral, renewal, extension or refunding is subordinate in right of payment to all other indebtedness of CSX or is not senior or prior in right of payment to the subordinated debt securities or ranks pari passu with or subordinate to the subordinated debt securities in right of payment; and provided that the subordinated debt securities will not constitute senior indebtedness. Swap agreements are defined as any financial agreement designed to manage our exposure to fluctuations in interest rates, currency exchange rates or commodity prices, including without limitation swap agreements, option agreements, cap agreements, floor agreements, collar agreements and forward purchase agreements.

     Senior indebtedness will be entitled to the benefits of the subordination provisions in the subordinated indenture irrespective of the amendment, modification or waiver of any term of the senior indebtedness. We may not amend the subordinated indenture to change the subordination of any outstanding subordinated debt securities without the consent of each holder of senior indebtedness that the amendment would adversely affect.

     If this prospectus is being delivered in connection with the offering of a series of subordinated debt securities, the accompanying prospectus supplement or the information incorporated by reference in this prospectus will set forth the approximate amount of senior indebtedness outstanding as of a recent date. The subordinated indenture does not limit the amount of senior indebtedness that we may issue.

DESCRIPTION OF THE TRUST PREFERRED SECURITIES

     The following is a summary of the principal terms of the trust preferred securities. The form of amended trust agreement is filed as an exhibit to the registration statement of which this prospectus forms a part, or is incorporated by reference. The terms of the trust preferred securities will include those stated in the amended trust agreement and those made part of the amended trust agreement by the Trust Indenture Act.

General

     The Trust will exist until terminated as provided in its amended trust agreement. Except under certain circumstances, CSX will be entitled to appoint, remove, or replace trustees, who will conduct the business and affairs of the Trust. The trustees of the Trust will consist of:

     The amended trust agreement will authorize the administrative trustees to issue, on behalf of the Trust, two classes of trust securities, trust preferred securities and trust common securities, each of which will have the terms described in this prospectus and in the applicable prospectus supplement. CSX will own all of the trust common securities. The trust common securities will rank equally in right of payment, and payments will be made on the trust common securities, proportionately with the trust preferred securities. However, if an event of default occurs and is continuing under the amended trust agreement, the rights of the holders of the trust common securities to payment of distributions and payments upon liquidation, redemption and otherwise, will be subordinated to the rights of the holders of the trust preferred securities. CSX will acquire, directly or indirectly, trust common securities in a total liquidation amount of approximately 3% of the total capital of the Trust.

     The proceeds from the sale of the trust preferred securities will be used by the Trust to purchase our subordinated debt securities. These subordinated debt securities will be held in trust by the property trustee for the benefit of the holders of the trust securities. CSX will guarantee the payments of distributions and payments on

21

redemption or liquidation with respect to the trust preferred securities, but only to the extent the Trust has funds available to make those payments and has not made the payments. See “Description of the Guarantee.”

     The assets of the Trust available for distribution to the holders of trust preferred securities will be limited to payments from us under the subordinated debt securities held by the Trust. If we fail to make a payment on the subordinated debt securities, the Trust will not have sufficient funds to make related payments, including distributions, on its trust preferred securities.

     The guarantee, when taken together with our obligations under the subordinated debt securities, the subordinated indenture and the amended trust agreement, will provide a full and unconditional guarantee of amounts due on the trust preferred securities issued by the Trust.

     The trust preferred securities will have the terms, including distributions, redemption, voting, liquidation rights and other preferred, deferred or other special rights or restrictions that will be described in the amended trust agreement or made part of the amended trust agreement by the Trust Indenture Act or the Delaware Statutory Trust Act. The terms of the trust preferred securities will mirror the terms of the subordinated debt securities held by the Trust. In other words, the distribution rate and the distribution payment dates and other payment dates for the trust preferred securities will correspond to the interest rate and interest payment dates and other payment dates on the subordinated debt securities. Holders of trust preferred securities have no preemptive or similar rights.

Provisions of a Particular Series

     The Trust may issue only one series of trust preferred securities. The applicable prospectus supplement will set forth the principal terms of the trust preferred securities that will be offered, including:

     The interest rate and interest and other payment dates of each series of subordinated debt securities issued to a trust will correspond to the rate at which distributions will be paid and the distribution and other payment dates of the trust preferred securities of that trust.

22

Extensions

     CSX has the right under the subordinated indenture to defer payments of interest on the subordinated debt securities by extending the interest payment period from time to time on the subordinated debt securities. The administrative trustees will give the holders of the trust preferred securities notice of any extension period upon their receipt of notice from us. If distributions are deferred, the deferred distributions and accrued interest will be paid to holders of record of the trust preferred securities as they appear on the books and records of the Trust on the record date next following the termination of such deferral period. See “Additional Terms of Subordinated Debt Securities – Option To Extend Interest Payment Period.”

Distributions

     Distributions on the trust preferred securities will be made on the dates payable to the extent that the Trust has funds available for the payment of distributions in the property account held by the property trustee. The Trust’s funds available for distribution to the holders of the trust securities will be limited to payments received from us on the subordinated debt securities. CSX has guaranteed the payment of distributions out of monies held by the Trust to the extent set forth under “Description of the Guarantee.”

     Distributions on the trust preferred securities will be payable to the holders named on the securities register of the Trust at the close of business on the record dates, which, as long as the trust preferred securities remain in book-entry only form, will be one business day prior to the relevant payment dates. Distributions will be paid through the property trustee who will hold amounts received in respect of the subordinated debt securities in the property account for the benefit of the holders of the trust securities. In the event that the trust preferred securities do not continue to remain in book- entry only form, the relevant record dates will conform to the rules of any securities exchange on which the trust preferred securities are listed and, if none, the administrative trustees will have the right to select relevant record dates, which will be more than 14 days but less than 60 days prior to the relevant payment dates. In the event that any date on which distributions are to be made on the trust preferred securities is not a business day, then payment of the distributions payable on that date will be made on the next succeeding day which is a business day and without any interest or other payment in respect of that delay, except that, if that business day is in the next succeeding calendar year, the payment will be made on the immediately preceding business day, in each case with the same force and effect as if made on the record date.

Mandatory Redemption of Trust Preferred Securities

     The trust preferred securities have no stated maturity date, but will be redeemed upon the maturity of the subordinated debt securities or to the extent the subordinated debt securities are redeemed prior to maturity. The subordinated debt securities will mature on the date specified in the applicable prospectus supplement and may be redeemed at any time, in whole but not in part, in certain circumstances upon the occurrence of a Tax Event or an Investment Company Event as described under “Special Event Redemption.”

     Upon the maturity of the subordinated debt securities, the proceeds of their repayment will simultaneously be applied to redeem all the outstanding trust securities at the applicable redemption price. Upon the redemption of the subordinated debt securities, either at our option or as a result of a Tax Event or an Investment Company Event, the proceeds from the redemption will simultaneously be applied to redeem trust securities having a total liquidation amount equal to the total principal amount of the subordinated debt securities so redeemed at the redemption price; provided, that holders of trust securities will be given not less than 20 nor more than 60 days’ notice of the redemption. In the event that fewer than all of the outstanding trust securities are to be redeemed, the trust securities will be redeemed proportionately.

Special Event Redemption

     Both a Tax Event and an Investment Company Event constitute Special Events for purposes of the redemption provisions described in the preceding paragraph.

23

     A Tax Event means that the administrative trustees have received an opinion of independent tax counsel experienced in those matters to the effect that, as a result of any amendment to, change or announced proposed change in:

which amendment or change becomes effective or proposed change, pronouncement, action or decision is announced on or after the date the trust preferred securities are issued and sold, there is more than an insubstantial risk that:

     An Investment Company Event means that the administrative trustees have received an opinion of a nationally recognized independent counsel to the effect that, as a result of an amendment to or change in the Investment Company Act or regulations thereunder on or after the date the trust preferred securities are issued and sold, there is more than an insubstantial risk that the Trust is or will be considered an investment company and be required to be registered under the Investment Company Act.

Redemption Procedures

     The Trust may not redeem fewer than all the outstanding trust securities unless all accrued and unpaid distributions have been paid on all trust securities for all distribution periods terminating on or before the date of redemption. In the event that fewer than all of the outstanding trust securities are to be redeemed, the trust securities will be redeemed proportionately.

     If the Trust gives a notice of redemption in respect of the trust securities (which notice will be irrevocable), then, by 12:00 noon, New York City time, on the redemption date, and if CSX has paid to the property trustee a sufficient amount of cash in connection with the related redemption or maturity of the subordinated debt securities, the property trustee will irrevocably deposit with the depositary funds sufficient to pay the applicable redemption price and will give the depositary irrevocable instructions and authority to pay the redemption price to the holders of the trust preferred securities, and the paying agent will pay the applicable redemption price to the holders of the trust common securities by check. If notice of redemption has been given and funds deposited as required, then, immediately prior to the close of business on the date of the deposit, distributions will cease to accrue and all rights of holders of trust preferred securities called for redemption will cease, except the right of the holders of the trust preferred securities to receive the redemption price but without interest on the redemption price. In the event that any date fixed for redemption of trust preferred securities is not a business day, then payment of the redemption price payable on that date will be made on the next succeeding day that is a business day, without any interest or other payment in respect of any such delay, except that, if that business day falls in the next calendar year, payment will be made on the immediately preceding business day. In the event that payment of the redemption price in respect of trust preferred securities is improperly withheld or refused and not paid either by the Trust or by CSX under the guarantee, distributions on the trust preferred securities will continue to accrue at the then applicable rate from the original redemption date to the date of payment, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the redemption price.

24

     Subject to the foregoing and applicable law, including, without limitation, U.S. federal securities laws, we or our subsidiaries may at any time, and from time to time, purchase outstanding trust preferred securities by tender, in the open market or by private agreement.

Conversion or Exchange Rights

     The terms on which the trust preferred securities are convertible into or exchangeable for common stock or our other securities will be contained in the applicable prospectus supplement. Those terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option, and may include provisions under which the number of shares of common stock or our other securities to be received by the holders of trust preferred securities would be subject to adjustment.

Distribution of the Subordinated Debt Securities

     CSX will have the right at any time to dissolve the Trust and, after satisfaction of the liabilities of creditors of the Trust as provided by applicable law, to cause subordinated debt securities to be distributed to the holders of the trust preferred securities in a total stated principal amount equal to the total stated liquidation amount of the trust preferred securities then outstanding. Prior to any such dissolution, we will obtain any required regulatory approvals. The right to dissolve the Trust and distribute the subordinated debt securities will be conditioned on our receipt of an opinion rendered by an independent tax counsel that the distribution would not result in the recognition of gain or loss for federal income tax purposes by the holders.

Liquidation Distribution upon Dissolution

     The amended trust agreement will state that the Trust will be dissolved:

     In the event of a dissolution, after the Trust pays all amounts owed to creditors, the holders of the trust preferred securities will be entitled to receive:

     If the Trust cannot pay the full amount due on its trust securities because insufficient assets are available for payment, then the amounts payable by the Trust on its trust securities will be paid proportionately. However, if an event of default under the related amended trust agreement occurs, the total amounts due on the trust preferred

25

securities will be paid before any distribution on the trust common securities. Under certain circumstances involving the dissolution of the Trust, subject to obtaining any required regulatory approval, subordinated debt securities will be distributed to the holders of the trust securities in liquidation of the Trust.

Trust Enforcement Events

     An event of default under the subordinated indenture relating to the subordinated debt securities will be an event of default under the amended trust agreement (a “Trust Enforcement Event”). See “Description of Debt Securities – Events of Default.”

     In addition, the voluntary or involuntary dissolution, winding up or termination of the Trust is also a Trust Enforcement Event, except in connection with:

     Under the amended trust agreement, the holder of the trust common securities will be deemed to have waived any Trust Enforcement Event with respect to the trust common securities until all Trust Enforcement Events with respect to the trust preferred securities have been cured, waived or otherwise eliminated. Until all Trust Enforcement Events with respect to the trust preferred securities have been so cured, waived, or otherwise eliminated, the property trustee will be deemed to be acting solely on behalf of the holders of the trust preferred securities and only the holders of the trust preferred securities will have the right to direct the property trustee with respect to certain matters under the amended trust agreement and the subordinated indenture. In the event that any Trust Enforcement Event with respect to the trust preferred securities is waived by the holders of the trust preferred securities as provided in the amended trust agreement, under the amended trust agreement the holders of trust common securities have agreed that the waiver also constitutes a waiver of the Trust Enforcement Event with respect to the trust common securities for all purposes under the amended trust agreement without any further act, vote or consent of the holders of trust common securities.

     CSX and the administrative trustees must file annually with the property trustee a certificate evidencing compliance with all the applicable conditions and covenants under the amended trust agreement.

     Upon the occurrence of a Trust Enforcement Event the property trustee, as the sole holder of the subordinated debt securities, will have the right under the subordinated indenture to declare the principal of, interest and premium, if any, on the subordinated debt securities to be immediately due and payable.

     If a property trustee fails to enforce its rights under the amended trust agreement or the subordinated indenture to the fullest extent permitted by law and subject to the terms of the amended trust agreement and the subordinated indenture, any holder of trust preferred securities may sue us, or seek other remedies, to enforce the property trustee’s rights under the amended trust agreement or the subordinated indenture without first instituting a legal proceeding against the property trustee or any other person. If a Trust Enforcement Event occurs and is continuing as a result of our failure to pay principal of or interest or premium, if any, on the subordinated debt securities when payable, then a holder of the trust preferred securities may directly sue us or seek other remedies, to collect its proportionate share of payments owed. See “Relationship Among the Trust Preferred Securities, the Guarantee and the Subordinated Debt Securities Held by the Trust.”

Removal and Replacement of Trustees

     Only the holders of trust common securities have the right to remove or replace the trustees of the Trust, except that while an event of default in respect of the subordinated debt securities has occurred or is continuing, the holders of a majority of the trust preferred securities will have this right. The resignation or removal of any trustee

26

and the appointment of a successor trustee will be effective only on the acceptance of appointment by the successor trustee in accordance with the provisions of the amended trust agreement.

Mergers, Consolidations or Amalgamations of the Trust

     The Trust may not consolidate, amalgamate, merge with or into, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to any other corporation or other body (each, a “Merger Event”), except as described below. The Trust may, with the consent of a majority of its administrative trustees and without the consent of the holders of its trust securities, consolidate, amalgamate, merge with or into, or be replaced by another trust, provided that:

     In addition, unless all of the holders of the trust preferred securities and trust common securities approve otherwise, the Trust will not consolidate, amalgamate, merge with or into, or be replaced by any other entity or permit any other entity to consolidate, amalgamate, merge with or into, or replace it, if, in the opinion of a nationally recognized tax counsel experienced in such matters, the transaction would cause the Trust or the successor entity to be classified other than as a grantor trust for U.S. federal income tax purposes.

27

Voting Rights; Amendment of Trust Agreement

     The holders of trust preferred securities have no voting rights except as discussed under “Mergers, Consolidations or Amalgamations of the Trust” and “Description of the Guarantee – Amendments”, and as otherwise required by law and the amended trust agreement.

     The amended trust agreement may be amended if approved by a majority of the administrative trustees of the Trust. However, if any proposed amendment provides for, or the administrative trustees otherwise propose to effect,

then the holders of the trust preferred securities as a single class will be entitled to vote on the amendment or proposal. In that case, the amendment or proposal will only be effective if approved by at least a majority in liquidation amount of the trust preferred securities affected by the amendment or proposal.

     No amendment may be made to an amended trust agreement if that amendment would:

     The holders of a majority of the total liquidation amount of the trust preferred securities have the right to:

     In addition, before taking any of the foregoing actions, the property trustee must obtain an opinion of counsel stating that, as a result of that action, the Trust will continue to be classified as a grantor trust for U.S. federal income tax purposes.

     As described in the form of amended trust agreement, holders of trust preferred securities may vote on a change at a meeting or by written consent.

28

     If a vote by the holders of trust preferred securities is taken or a consent is obtained, any trust preferred securities owned by CSX or any of our affiliates will, for purposes of the vote or consent, be treated as if they were not outstanding, which will have the following consequences:

Information Concerning the Property Trustee

     JPMorgan Chase Bank will be the property trustee. JPMorgan Chase Bank will also be the guarantee trustee, the subordinated indenture trustee and the senior indenture trustee. CSX and certain of our affiliates may from time to time maintain deposit accounts and other banking relationships with JPMorgan Chase Bank. JPMorgan Chase Bank also serves as trustee under other indentures pursuant to which securities of CSX are outstanding. See “Description of Debt Securities – Concerning the Trustees.”

     For matters relating to compliance with the Trust Indenture Act, the property trustee will have all of the duties and responsibilities of an indenture trustee under the Trust Indenture Act. The property trustee, other than during the occurrence and continuance of a Trust Enforcement Event, undertakes to perform only the duties that are specifically described in the amended trust agreement and, upon a Trust Enforcement Event, must use the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the property trustee is under no obligation to exercise any of the powers given it by the applicable amended trust agreement at the request of any holder of trust preferred securities unless it is offered reasonable security or indemnity against the costs, expenses and liabilities that it might incur.

It is an affiliate of JPMorgan Chase Bank, which will serve as property trustee and in the other capacities described above under “Information Concerning the Property Trustee.”

Information Concerning the Administrative Trustees

     The administrative trustees are authorized and directed to conduct the affairs of and to operate the Trust in a way that:

     CSX and the administrative trustees are authorized to take any action, so long as it is not inconsistent with applicable law or the certificate of trust or amended trust agreement, that we and the administrative trustees determine to be necessary or desirable for those purposes.

DESCRIPTION OF THE GUARANTEE

     CSX will execute the guarantee from time to time for the benefit of the holders of the trust preferred securities.

     JPMorgan Chase Bank will act as guarantee trustee under the guarantee. The guarantee trustee will hold the guarantee for the benefit of the holders of the trust preferred securities.

     The following description of the guarantee is only a summary. The form of guarantee is an exhibit to the registration statement.

General

     CSX will irrevocably and unconditionally agree under the guarantee to pay the guarantee payments that are defined below, to the extent specified in the guarantee, to the holders of the trust preferred securities, to the extent that the guarantee payments are not paid by or on behalf of the Trust. We are required to pay the guarantee payments to the extent specified in the guarantee regardless of any defense, right of set-off or counterclaim that we may have or may assert against any person.

     The following payments and distributions on the trust preferred securities of the Trust are guarantee payments:

     We may satisfy our obligation to make a guarantee payment by making that payment directly to the holders of the related trust preferred securities or by causing the Trust to make the payment to those holders.

     The guarantee will be a full and unconditional guarantee, subject to certain subordination provisions, of the guarantee payments with respect to the trust preferred securities from the time of issuance of the trust preferred securities, except that the guarantee will only apply to the payment of distributions and other payments on the trust preferred securities when the Trust has sufficient funds legally and immediately available to make those distributions or other payments.

     If CSX does not make the required payments on the subordinated debt securities that the property trustee holds under the Trust, the Trust will not make the related payments on the trust preferred securities.

Subordination

     Our obligations under the guarantee will be unsecured obligations. Those obligations will rank:

30

     CSX has no subordinated debt securities outstanding that will rank equal in priority with the guarantee. CSX has common stock outstanding that will rank junior to the guarantee.

     The guarantee will be a guarantee of payment and not of collection. This means that the guaranteed party may institute a legal proceeding directly against us, as guarantor, to enforce its rights under the guarantee without first instituting a legal proceeding against any other person or entity.

     The terms of the trust preferred securities will provide that each holder of the trust preferred securities, by accepting those trust preferred securities, agrees to the subordination provisions and other terms of the guarantee.

Amendments

     CSX may amend the guarantee without the consent of any holder of the trust preferred securities to which the guarantee relates if the amendment does not materially and adversely affect the rights of those holders. We may otherwise amend the guarantee with the approval of the holders of at least 50% of the outstanding trust preferred securities to which the guarantee relates.

Termination

     The guarantee will terminate and be of no further effect when:

     The guarantee will remain in effect or will be reinstated if at any time any holder of the related trust preferred securities must restore payment of any sums paid to that holder with respect to those trust preferred securities or under the guarantee.

Material Covenants

     CSX will covenant that, so long as any trust preferred securities remain outstanding, if there is an event of default under the guarantee or under the subordinated indenture for the related subordinated debt securities or during an extension of the interest payment period for the related subordinated debt securities:

31

     We may, however, make the following types of distributions:

     Because we are a holding company that conducts all of our operations through our subsidiaries, our ability to meet our obligations under the guarantee is dependent on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends or to advance or repay funds to us. The Trust, as holder of the guarantee and the subordinated debt securities will generally have a junior position to claims of creditors of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and any preferred shareholders.

Events of Default

     An event of default will occur under the guarantee if we fail to perform any of our payment obligations under the guarantee. The holders of a majority of the trust preferred securities of any series may waive any such event of default and its consequences on behalf of all of the holders of the trust preferred securities of that series. The guarantee trustee is entitled to enforce the guarantee for the benefit of the holders of the trust preferred securities of a series if an event of default occurs under the related guarantee. The holders of a majority of the trust preferred securities to which the guarantee relates have the right to direct the time, method and place of conducting any proceeding for any remedy available to the guarantee trustee with respect to the guarantee or to direct the exercise of any trust or power that the guarantee trustee holds under the guarantee. Any holder of the related trust preferred securities may institute a legal proceeding directly against us to enforce that holder’s rights under the guarantee without first instituting a legal proceeding against the guarantee trustee or any other person or entity.

Concerning the Guarantee Trustee

     JPMorgan Chase Bank will be the guarantee trustee. It will also serve as the property trustee, the subordinated indenture trustee and the senior indenture trustee. We and certain of our affiliates may from time to time maintain deposit accounts and other banking relationships with JPMorgan Chase Bank and its affiliates. JPMorgan Chase Bank also serves as trustee under another indenture pursuant to which securities of CSX are outstanding. See “Description of Debt Securities – Concerning the Trustees.” The guarantee trustee will perform only those duties that are specifically set forth in each guarantee unless an event of default under the guarantee occurs and is continuing. In case an event of default occurs and is continuing, the guarantee trustee will exercise the same degree of care as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. Subject to those provisions, the guarantee trustee is under no obligation to exercise any of its powers under any guarantee at the request of any holder of the related trust preferred securities unless that holder offers reasonable indemnity to the guarantee trustee against the costs, expenses and liabilities which it might incur as a result.

Agreement as to Expenses and Liabilities

     CSX will enter into an agreement as to expenses and liabilities as required under the trust agreement. The agreement as to expenses and liabilities will provide that we will, with certain exceptions, irrevocably and unconditionally guarantee the full payment of any indebtedness, expenses or liabilities of the Trust to each person or entity to whom the Trust becomes indebted or liable. The exceptions are the obligations of the Trust to pay to the holders of the trust common securities or other similar interests in the Trust the amounts due to the holders under the terms of the trust common securities or the similar interests.

32

RELATIONSHIP AMONG THE TRUST PREFERRED SECURITIES, THE GUARANTEE AND THE
SUBORDINATED DEBT SECURITIES HELD BY THE TRUST

     CSX will guarantee payments of distributions and redemption and liquidation payments due on the trust preferred securities, to the extent the Trust has funds available for the payments, as described under “Description of the Guarantee.” No single document executed by us in connection with the issuance of the trust preferred securities will provide for our full, irrevocable and unconditional guarantee of the trust preferred securities. It is only the combined operation of our obligations under the guarantee, the amended trust agreement and the subordinated indenture that has the effect of providing a full, irrevocable and unconditional guarantee of the Trust’s obligations under the trust preferred securities.

     As long as we make payments of interest and other payments when due on the subordinated debt securities held by the Trust, those payments will be sufficient to cover the payment of distributions and redemption and liquidation payments due on the trust preferred securities issued by the Trust, primarily because:

     If, and to the extent that, we do not make payments on the subordinated debt securities, the Trust will not have funds available to make payments of distributions or other amounts due on its trust preferred securities. In those circumstances, you will not be able to rely upon the guarantee for payment of these amounts. Instead, you may directly sue us or seek other remedies to collect your proportionate share of payments owed. If you sue us to collect payment, then we will assume your rights as a holder of trust preferred securities under the amended trust agreement to the extent we make a payment to you in any such legal action.

ACCOUNTING TREATMENT

     The Trust will be treated as a subsidiary of ours for financial reporting purposes. Accordingly, our consolidated financial statements will include the accounts of the Trust. The trust preferred securities, along with other trust preferred securities that we guarantee on an equivalent basis, will be presented as a separate line item in our consolidated balance sheets, and appropriate disclosures about the trust preferred securities, the guarantee and the subordinated debt securities will be included in the notes to the consolidated financial statements. We will record distributions that the Trust pays on the trust preferred securities as an expense in our consolidated statement of income.

DESCRIPTION OF CAPITAL STOCK

     As of the date of this prospectus, the authorized capital stock of CSX is (i) 300,000,000 shares of common stock, par value $1.00 per share, and (ii) 25,000,000 shares of preferred stock, without par value, issuable in series. As of March 5, 2004, 215,069,189 shares of common stock were issued and outstanding, and no shares of preferred stock were outstanding.

     The following summary of certain provisions of the common stock, preferred stock, Amended and Restated Articles of Incorporation and Bylaws of CSX do not purport to be complete and are qualified in their entirety by reference to the Amended and Restated Articles of Incorporation and the Bylaws, copies of which have been incorporated by reference as exhibits to the registration statement.

33

Common Stock

     CSX may issue shares of common stock, either separately, or together with, or upon the conversion of or in exchange for, other securities. If we offer common stock, the specific terms of the offering, including the number of shares offered and the initial public offering price, will be described in the applicable prospectus supplement.

     CSX common stock is listed on the New York Stock Exchange under the symbol “CSX.” All outstanding shares of common stock are fully-paid and non-assessable. Any additional shares of common stock we issue will also be fully-paid and non-assessable. Holders of common stock are entitled to one vote per share on all matters voted on by shareholders, including elections of directors, and, except as otherwise required by law or provided by the express provisions of any series of preferred stock, the holders of those shares exclusively possess all voting power of CSX. There is no cumulative voting in the election of directors, and no holder of common stock is entitled as such, as a matter of right, to subscribe for or purchase any shares of common stock or preferred stock. Subject to the preferential rights of any outstanding series of preferred stock, the holders of common stock are entitled to receive ratably dividends as may be declared from time to time by our Board of Directors from funds legally available for that purpose. In the event of a liquidation, dissolution or winding up of CSX, holders of common stock are entitled to share ratably in all assets remaining after payment or provision for liabilities and amounts owing in respect of any outstanding preferred stock.

     The transfer agent for CSX common stock is Computershare Investor Services (successor to Harris Trust Company), located in Chicago, Illinois.

Preferred Stock

     CSX may issue shares of our preferred stock, in one or more series, either separately, or together with, or upon the conversion of or in exchange for, other securities.

     The following description of preferred stock sets forth certain general terms and provisions of any series of preferred stock to which any prospectus supplement may relate. If we offer preferred stock, the terms of any particular series of preferred stock, including preferred stock to be represented by depositary shares, will be described in the applicable prospectus supplement, including (where applicable):

34

     The form of articles of amendment relating to a series of offered preferred stock will be filed as an exhibit to or incorporated by reference in the registration statement. The terms of the preferred stock offered under any prospectus supplement may differ from the general terms set forth in this prospectus.

     Preferred stock may be issued from time to time in one or more series. Subject to limitations prescribed by Virginia law and the Amended and Restated Articles of Incorporation, our Board of Directors, without further action by the shareholders, is authorized to designate and issue in series preferred stock and to fix as to any series:

     The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of common stock and, under certain circumstances, make it more difficult for a third party to gain control of CSX or remove present management and could have the effect of delaying or preventing a merger, tender offer or other attempted takeover of CSX. No holder of preferred stock will be entitled, as a matter of right, to subscribe for or purchase any shares of preferred stock or common stock.

     Preferred stock will, when issued, be fully-paid and non-assessable. Unless otherwise specified in the applicable prospectus supplement, any series of offered preferred stock will rank, with respect to dividends and the distribution of assets, senior to common stock, and on a parity with shares of any other outstanding series of preferred stock. Therefore, any preferred stock that may subsequently be issued may limit the rights of the holders of our common stock and preferred stock. In addition, under certain circumstance, preferred stock could also restrict dividend payments to our holders of common stock.

     The transfer agent and registrar for a series of preferred stock will be named in the applicable prospectus supplement.

Virginia Stock Corporation Act; Anti-takeover Effects

     The Virginia Stock Corporation Act contains provisions governing “Affiliated Transactions.” These provisions, with several exceptions discussed below, generally require approval of certain material transactions between a Virginia corporation and any beneficial holder of more than 10% of any class of its outstanding voting shares (an “Interested Shareholder”) by a majority of disinterested directors and by the holders of at least two-thirds of the remaining voting shares. Affiliated Transactions subject to this approval requirement include mergers, share

35

exchanges, material dispositions of corporate assets not in the ordinary course of business, any dissolution of the corporation proposed by or on behalf of an Interested Shareholder, or any reclassification, including reverse stock splits, recapitalization or merger of the corporation with its subsidiaries, which increases the percentage of voting shares owned beneficially by an Interested Shareholder by more than 5%.

     For three years following the time that an Interested Shareholder becomes an owner of 10% of the outstanding voting shares, a Virginia corporation cannot engage in an Affiliated Transaction with that Interested Shareholder without the approval of two-thirds of the voting shares other than those shares beneficially owned by the Interested Shareholder, and the approval of a majority of the Disinterested Directors. “Disinterested Director” means, with respect to a particular Interested Shareholder, a member of our Board of Directors who was:

After the expiration of the three-year period, the statute requires approval of Affiliated Transactions by two-thirds of the voting shares other than those beneficially owned by the Interested Shareholder.

     The principal exceptions to the special voting requirements apply to transactions proposed after the three-year period has expired and require either that the transaction be approved by a majority of CSX’s Disinterested Directors or that the transaction satisfy the fair-price requirements of the statute. In general, the fair-price requirement provides that in a two-step acquisition transaction, the Interested Shareholder must pay the shareholders in the second step either the same amount of cash or the same amount and type of consideration paid to acquire CSX’s shares in the first step.

     None of the limitations and special voting requirements described above applies to an Interested Shareholder whose acquisition of shares making that person an Interested Shareholder was approved by a majority of CSX’s Disinterested Directors.

     These provisions are designed to deter certain types of takeovers of Virginia corporations. The statute provides that, by affirmative vote of a majority of the voting shares other than shares owned by any Interested Shareholder, a corporation can adopt an amendment to its articles of incorporation or bylaws providing that the Affiliated Transactions provisions will not apply to the corporation. CSX has not “opted out” of the Affiliated Transactions provisions.

     Virginia law also generally provides that shares of a Virginia corporation acquired in a transaction that would cause the acquiring person’s voting strength to meet or exceed any of three thresholds (20%, 33-1/3% or 50%) have no voting rights with respect to those shares unless granted by a majority vote of shares not owned by the acquiring person or any officer or employee-director of the corporation. This provision empowers an acquiring person to require the Virginia corporation to hold a special meeting of shareholders to consider the matter within 50 days of its request. The Board of Directors of a Virginia corporation can opt out of this provision at any time before four days after receipt of a control share acquisition notice.

DESCRIPTION OF DEPOSITARY SHARES

     CSX may offer depositary shares (either separately or together with other securities) representing fractional interests in shares of our preferred stock of any series. In connection with the issuance of any depositary shares, CSX will enter into a deposit agreement with a bank or trust company, as depositary, which will be named in the applicable prospectus supplement. Depositary shares will be evidenced by depositary receipts issued pursuant to the related deposit agreement. Immediately following the issuance by CSX of the preferred stock related to the depositary shares, we will deposit the shares of preferred stock with the relevant preferred stock depositary and will cause the preferred stock depositary to issue, on our behalf, the related depositary receipts. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fraction of a share of preferred stock represented by the related depositary share, to all the rights, preferences and privileges of, and will

36

be subject to all of the limitations and restrictions on, the preferred stock represented by the depositary receipt (including, if applicable, dividend, voting, conversion, exchange, redemption and liquidation rights).

     The form of deposit agreement, together with the form of related depositary receipt, that will be entered into with respect to a particular offering of depositary shares will be filed as an exhibit to or incorporated by reference in the registration statement.

     The applicable prospectus supplement will describe the terms of the depositary shares and the related deposit agreement for a particular issue of depositary shares, which terms may include the following if applicable to those depositary shares:

DESCRIPTION OF SECURITIES WARRANTS

     CSX may issue, either separately or together with other securities, securities warrants for the purchase of debt securities, preferred stock or common stock. Each securities warrant will entitle the holder to purchase the principal amount of debt securities or number of shares of preferred stock or common stock, as the case may be, at the exercise price and in the manner specified in the prospectus supplement relating to those securities warrants. Securities warrants may be exercised at any time up to the date and time specified in the applicable prospectus supplement.

     Securities warrants will be issued under one or more warrant agreements to be entered into between CSX and a bank or trust company, as warrant agent. The material terms and provisions of the warrant agreement for a particular issue of securities warrants will be set forth in the applicable prospectus supplement. The form of securities warrant agreement, including the form of certificates representing the securities warrants, that will be entered into with respect to a particular offering of securities warrants will be filed as an exhibit to or incorporated by reference in the registration statement.

     The applicable prospectus supplement will describe the terms of the securities warrants for a particular issue of securities warrants, which terms may include the following if applicable to those securities warrants:

37

PLAN OF DISTRIBUTION

     CSX may sell securities to one or more underwriters for public offering and sale by them or may sell securities to institutional investors directly or through agents who solicit or receive offers on our behalf or through dealers or through a combination of any of these methods of sale. The prospectus supplement with respect to particular securities will set forth the terms of the offering of those securities, including the following:

     Underwriters may offer and sell the securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. We also may offer and sell securities in exchange for one or more of our outstanding issues of debt. We may, from time to time, authorize agents acting on a best or reasonable efforts basis as our agents to solicit or receive offers to purchase the securities upon the terms and conditions as are set forth in the applicable prospectus supplement. In connection with the sale of securities, underwriters or agents may be deemed to have received compensation from CSX in the form of underwriting discounts or commissions and may also receive commissions from purchasers of securities for whom they may act as agent. Underwriters may sell securities to or through

38

dealers, and dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent.

     Underwriters, dealers and agents who participate in the distribution of securities and their controlling persons may be entitled, under agreements that may be entered into with CSX, to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that the underwriters, dealers or agents and their controlling persons may be required to make in respect of those liabilities.

     If so indicated in the applicable prospectus supplement, we may authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to contracts providing for payment and delivery on a future date. Institutions with which those contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases those institutions must be approved by us. The obligations of any institutional purchaser under those contracts will not be subject to any conditions except:

     Each series of offered securities other than common stock will be a new issue of securities with no established trading market. Any underwriters to whom offered securities are sold by CSX for public offering and sale may make a market in such offered securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any offered securities.

     Any underwriter may engage in stabilizing and syndicate covering transactions in accordance with Rule 104 under the Exchange Act. Rule 104 permits stabilizing bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. The underwriters may over-allot offered securities, thereby creating a short position in the underwriters’ account. Syndicate covering transactions involve purchases of offered securities in the open market after the distribution has been completed to cover syndicate short positions. Stabilizing and syndicate covering transactions may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions. These transactions, if commenced, may be discontinued at any time.

     Certain of the underwriters, dealers or agents and their affiliates may engage in transactions with and perform services for CSX in the ordinary course of business.

LEGAL OPINIONS

     McGuireWoods LLP, Richmond, Virginia will issue an opinion concerning the validity of the offered securities for CSX. Robert L. Burrus, Jr., a partner of McGuireWoods LLP, is a director of CSX. Certain matters relating to the formation of the Trust and the issuance of the trust preferred securities under Delaware law and the trust agreements will be passed upon by Richards, Layton & Finger, P.A., special Delaware counsel to the Trust and CSX. Any underwriter, dealer or agent will be advised about other issues relating to any offering by its own legal counsel.

EXPERTS

     Ernst & Young LLP, independent auditors, have audited CSX’s consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 26, 2003, as set forth in their report, which is incorporated by reference in this prospectus and elsewhere in the registration statement.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution*

     The following table sets forth the expenses other than underwriting discounts and commissions (all of which will be paid by CSX) to be incurred in connection with the registration and sale of the securities:

Item 15. Indemnification of Directors and Officers

     Article 10 of the Virginia Stock Corporation Act allows, in general, for indemnification, in certain circumstances, by a corporation of any person threatened with or made a party to any action, suit or proceeding by reason of the fact that he or she is, or was, a director, officer, employee or agent of such corporation. Indemnification is also authorized with respect to a criminal action or proceeding where the person had no reasonable cause to believe that his or her conduct was unlawful. Article 9 of the Virginia Stock Corporation Act provides limitations on damages payable by officers and directors, except in cases of willful misconduct or knowing violation of criminal law or any federal or state securities law.

     Article VII of CSX’s Amended and Restated Articles of Incorporation provides for mandatory indemnification of any director or officer of CSX who is, was or is threatened to be made a party to any proceeding (including any proceeding by or on behalf of CSX) by reason of the fact that he or she is or was a director or officer of CSX against all liabilities and reasonable expenses incurred in the proceeding, except such liabilities and expenses as are incurred because of such director’s or officer’s willful misconduct or knowing violation of the criminal law.

     CSX’s Amended and Restated Articles of Incorporation also provide that in every instance permitted under Virginia corporate law in effect from time to time, the liability of a director or officer of CSX to CSX or our shareholders arising out of a single transaction, occurrence or course of conduct will be limited to one dollar.

     CSX maintains a standard policy of officers’ and directors’ liability insurance.

     The underwriting, distribution or similar agreements filed or to be filed as exhibits to the registration statement will contain provisions regarding indemnification of CSX’s officers, directors and controlling persons against certain liabilities.

Item 17. Undertakings

     Each of the undersigned registrants hereby undertakes:

     (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

provided, however, that subparagraphs (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those subparagraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement.

     (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

     Each of the undersigned registrants hereby undertakes that, for the purpose of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrants, pursuant to the provisions described under Item 15 or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification by it is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-4

     Each of the undersigned registrants hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     Each of the undersigned registrants hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)2 of the Act.
